Researching Rudeness: The Past, Present, and Future of the Science of Incivility

Incivility refers to rude, condescending, and ostracizing acts that violate workplace norms of respect, but otherwise appear mundane. Organizations sometimes dismiss these routine slights and indignities—which lack overt malice—as inconsequential. However, science has shown that incivility is a real stressor with real consequences: though the conduct is subtle, the consequences are not. We now know a great deal about how common incivility is, who gets targeted with it, under what conditions, and with what effects. The first half of this article reviews and synthesizes the last 15 years of workplace incivility research. In the second half, we look beyond that body of scholarship to pose novel questions and nudge the field in novel directions. We also point to thorny topics that call for caution, even course correction. Incivility in organizations is as important now as ever. Our goal is to motivate new science on incivility, new ways to think about it and, ultimately, new solutions.
Fast pixel-box for pedestrian detection

Inspired by regression for detection task, We propose a new method called Pixel-Box. Prior work on regression for object detection can not match small pedestrian. Instead, Pixel-Box is only uses one feature map pixel of each channel to regress offset of boxes and then uses all feature map to predict which position has object. The model has two sibling network at the end of convolution output, but simply forward and backward once for both training and testing. It is an end to end system can directly optimized by loss function. To improve accuracy, we present a new backward method directly impact the model input and appropriate change the input image to re-forward the network. We evaluate this method on Caltech benchmark, also presenting competitive speed.
Meso-and Nanostructuring of Industrial Cu / ZnO / ( Al 2 O 3 ) Catalysts

A concept is presented, which helps to rationalize the success of the industrially applied preparation route for Cu/ZnO/(Al2O3) catalysts. Many studies can be found in the open literature, which describe the critical dependency of the final catalyst’s properties on precursor chemistry. In line with previous reports, this concept identifies zincian malachite as the relevant precursor phase and includes a simple relation of precursor crystal structure and final Cu surface area. It comprises two hierarchical microstructure-directing effects, for which particle morphology and degree of Cu substitution by Zn in the zincian malachite phase are the key properties: (i) meso-structuring of the precursor phase upon ageing of the coprecipitate in the mother liquor and (ii) nano-structuring of the oxide phase upon decomposition. Consequences for further optimization of the Cu,Zn,Al system are discussed.
Online power management using DVFS for RTOS

Power management is essential in microprocessor-based system design to avoid heat dissipation and preserve battery life time. In mobile devices running real time applications, the power consumed by the CPU can be more than the needed amount of power for best performance. At first glance, one can think of reducing the power budget of the system. Although this may seem an appealing easy solution, it can cause a huge degradation in performance if not controlled properly. Also a real time application's requirements vary with time, which implies that the power budget should also be variable. There must be a trade-off between power management and performance such that, the power consumed is always proportional to the required performance level. DVFS (Dynamic Voltage and Frequency Scaling) can be used to change the operating point (voltage-frequency pair) of the CPU according to the application's power requirement. In this paper, we present an implementation of a negative feedback control algorithm that uses DVFS for power saving in soft real-time systems that runs on Mentor Graphics® Nucleus® RTOS. A monitor periodically calculates the CPU utilization in runtime and reports it to the controller which adjusts the CPU operating point online such that the best performance is achieved with least power consumption. Our experimental results show that power savings up to 24% can be achieved just by using the proposed DVFS on a platform that supports only frequency scaling.
A Bipolar High-Voltage Pulsed-Power Supply Based on Capacitor-Switch Voltage Multiplier

This paper presents a power electronics converter to generate bipolar high-voltage pulses using low-voltage dc source. Converter is designed based on charging of different capacitors by a predetermined switching pattern and their discharging on the load for pulsed power applications. Low number of power electronics devices and bulky transformer elimination are main advantages of the proposed converter. According to new findings, bipolar high-voltage pulses may lead to higher efficiency in many applications, such as food sterilization industry. The proposed pulse generator generates bipolar controllable pulses with a modular circuit structure based on a capacitor-switched network. Experimental results are presented to verify the analysis.
Age 17 language and reading outcomes in late-talking toddlers: support for a dimensional perspective on language delay.

PURPOSE This study examined whether late talkers identified at 24-31 months continued to have weaker language and reading skills at 17 years of age than typically developing peers. METHOD Language and reading outcomes at 17 years of age were examined in 26 children identified as late talkers with normal nonverbal ability and normal receptive language at intake and in 23 typically developing children matched at intake on age, socioeconomic status (SES), and nonverbal ability. RESULTS Although late talkers performed in the average range on all language and reading tasks at 17 years of age, they obtained significantly lower Vocabulary/Grammar and Verbal Memory factor scores than SES-matched peers. The age 17 Vocabulary/Grammar factor had large correlations with the age 17 Verbal Memory and Reading/Writing factors. The age 17 Vocabulary/Grammar and Reading/Writing factors were strongly predicted by comparable factors at 13 years of age. Age 2 Language Development Survey (L. Rescorla, 1989) vocabulary score explained 17% of the variance in the age 17 Vocabulary/Grammar and Verbal Memory factors. CONCLUSIONS Results suggest that slow language development at 24-31 months is associated with a weakness in language-related skills into adolescence relative to skills manifested by typically developing peers--findings that are consistent with a dimensional perspective on language delay.
Evaluation of antimicrobial and antioxidant properties of Mondia whytei roots extracts.

Extracts of Mondia whytei (M. whytei) root barks were screened for their inhibitory effects against Staphylococcus aureus (S. aureus) (ATCC 25923), Escherichia coli (E. coli) 0157:H7 (PSSCMI 0032), Bacillus subtilis, Candida albicans and Aspergillus niger were used as test organisms. From the results it was concluded that activity varied with the solvent used. Contrary to previous reports, the plant seems to lack significant antibacterial activity except against E. coli. The popularity of a herbal recipe is not always a measure for its potency. However, M. whytei had antifungal activity since the ethanol and methanol extracts showed significant activity against the tested strains of fungi. The antioxidant activity of the extracts was also evaluated using the DPPH free radical scavenging assay. M. whytei exhibited substantial inhibition of the DPPH activity with EC50 of 413mg/l for the crude extracts. This antioxidant activity of the crude extracts can be attributed to the presence of 2-Hydroxy-4-Methoxybenzaldehyde that is a known antioxidant in the root extracts.
Numerical research on a dual-mode sampled-grating quantum-dot-based InP/InGaAs/InGaAsP DFB laser for W-band RoF application

In this paper, we design and simulate an InP/InGaAs/InGaAsP dual-mode sampled Bragg grating quantum-dot (QD) based distributed feedback (DFB) laser constituted with alternating grating and FP sections in both COMSOL Multiphysics 4.3 and VPI Transmission Maker 8.9. Sampled grating (SG) reflection spectrum is simulated based on transfer matrix method. 2D and 3D optical mode analysis is implemented in COMSOL. In theory, the Coupled-Mode Equation (CME) is used to numerically description the dynamic behavior of this DFB laser. At the meantime, QD laser space and mode model is simulated and verified in COMSOL Multiphysics 4.3. The design QD Laser emitting wavelength is 1550 nm. The mode spacing in W-band millimetre-wave domain (75GHz) and side-mode-suppression-ratio (SMSR) as high as 50dB are achieved. Finally, a spectral pure and stable 75GHz mm-wave signal with 3-dB linewidth of 10MHz is observed on an electrical spectrum analyser after beating on a wideband photodiode in VPI Transmission Maker 8.9 software.
Assessing Financial Education: Evidence from Boot Camp

This study estimates the effects of Personal Financial Management Course attendance and enrollment assistance using a natural experiment in the US Army. New enlistees' course attendance reduces the probability of having credit account balances, average balances, delinquencies, and adverse legal actions in the first year after the course, but it has no effects on accounts in the second year or credit scores in either year. The course and its enrollment assistance substantially increase retirement savings rates and average monthly contributions, with effects that persist through at least two years. The course has no significant effects on military labor market outcomes. (JEL D14, I21, J45)
A compact dual-band filtering microstrip antenna with the same polarization planes

A novel compact dual-band filtering antenna operated in WLAN bands is presented. The proposed design is composed of a slot-loaded patch and a half-wavelength stepped-impedance resonator with the same apertured ground. Full-wave simulator HFSS is used to extract the coupling coefficients in order to determine the physical dimension of the apertures. The antenna provides good selectivity and the same polarization planes in 2.4 GHz and 5.2 GHz bands. The measurement results agree with the simulated ones.
Electron-electron interactions and doping dependence of the two-phonon Raman intensity in graphene

Raman spectroscopy is a fast and nondestructive means to characterize graphene samples. In particular, the Raman spectra are strongly affected by doping. While the resulting change in position and width of the $G$ peak can be explained by the nonadiabatic Kohn anomaly at $\ensuremath{\Gamma}$, the significant doping dependence of the $2D$ peak intensity has not been understood yet. Here we show that this is due to a combination of electron-phonon and electron-electron scattering. Under full resonance, the photogenerated electron-hole pairs can scatter not just with phonons but also with doping-induced electrons or holes, and this changes the intensity. We explain the doping dependence and show how it can be used to determine the corresponding electron-phonon coupling. This is higher than predicted by density-functional theory, as a consequence of renormalization by Coulomb interactions.
Collaborative Research : Further Developments in the Global Resolution of Convex Programs with Complementary Constraints Final Report 2011 – 2014

We have developed methods for finding globally optimal solutions to various classes of nonconvex optimization problems. We have shown that any nonconvex conic quadratically constrained quadratic program can be lifted to a convex conic optimization problem. We have shown that a complementarity approach can be used to find sparse solutions to optimization problems, with promising initial theoretical and computational results. We have investigated various relaxation approaches to several classes of problems with complementarity constraints, including linear programs with complementarity constraints, support vector regression parameter selection, bi-parametric linear complementarity constrained linear programs, quadratic programs with complementarity constraints, and nonconvex quadratically constrained quadratic programs, proving various theoretical results for each of these problems as well as demonstrating the computational effectiveness of our approaches.
An Exploratory Study of Mobile Collaborative Learning in Developing Regions

Researchers have studied how game-based approaches to education might have impact in resource-constrained regions. However, the use of mobile technology, which allows freedom of movement and thus potentially enables more natural game-play behaviour, has not been extensively explored in the context of collaborative learning. In this paper, we explore two mobile-based approaches for using collaborative game-play to supplement ESL (English as a Secondary Language) education in developing regions: (1) Mobile Single Display Groupware: a pico-projector connected to a cell phone, with a handheld controller for each child to interact, and (2) Mobile Multiple Display Groupware: a cell phone for each child. Our exploration considers the types of interaction that occur in both of these conditions, and the impact on learning outcomes. Our observations also provide insights for the future design of games in this context.
On the Degradation of MEMS Gyroscope Performance in the Presence of High Power Acoustic Noise

Due to their reduced size, cost, and power requirements relative to traditional gyroscopes, MEMS gyroscopic sensors are finding increasing use in many applications. It is well known that unshielded MEMS gyroscopes can be vulnerable to both mechanical shock and high frequency vibrations. The results of this investigation indicate that MEMS gyroscopes are also susceptible to high power, high frequency content acoustic noise. Acoustic energy frequency components that are close to the resonating frequency of the proof mass in the MEMS gyroscope can produce undesirable motion of the proof mass, resulting in corruption in the angular rate measurement. If the acoustic signals possess enough power in the vicinity of the sensor resonating frequency, the resulting degradation in sensor performance can be severe enough to render the angular rate measurements useless.
Design of a wearable sensing system for a lower extremity exoskeleton

Assistive type lower extremity exoskeletons (ASLEE) which serve the lower limb disabilities always operate under a customized gait to achieve the dream of walking again. However, the customized gait is rigid that cannot provide stable motion for variation of terrain features. For the purpose of realizing intelligent control for an ASLEE named AIDER, a novel wearable sensing system which can realize posture and ground reaction force detection is proposed. The wearable sensing system employs 7 force sensors as a sensing matrix to achieve high accuracy of ground reaction force detection. One more IMU sensor is integrated into the wearable sensing system to realize 6-DOF posture capture.
Wage–size relation and the structure of work-force composition in Italian manufacturing firms

In this paper we study the impact of firms' productivity and scale of activity on the cost of labour for Italian manufacturing firms, investigating how the work-force composition affects the total expenditures for wages. Our analysis reveals that once productivity differences among firms are accounted for, size still retains a positive effect on cost of labour. We show that the source of this phenomenon is the relatively higher proportion of non-production workers in bigger firms, which results in a cost of labour for white collar workers that increases with increasing firm size.

Glyphosate and aminomethylphosphonic acid are not detectable in human milk.

BACKGROUND Although animal studies have shown that exposure to glyphosate (a commonly used herbicide) does not result in glyphosate bioaccumulation in tissues, to our knowledge there are no published data on whether it is detectable in human milk and therefore consumed by breastfed infants. OBJECTIVE We sought to determine whether glyphosate and its metabolite aminomethylphosphonic acid (AMPA) could be detected in milk and urine produced by lactating women and, if so, to quantify typical consumption by breastfed infants. DESIGN We collected milk (n = 41) and urine (n = 40) samples from healthy lactating women living in and around Moscow, Idaho and Pullman, Washington. Milk and urine samples were analyzed for glyphosate and AMPA with the use of highly sensitive liquid chromatography-tandem mass spectrometry methods validated for and optimized to each sample matrix. RESULTS Our milk assay, which was sensitive down to 1 μg/L for both analytes, detected neither glyphosate nor AMPA in any milk sample. Mean ± SD glyphosate and AMPA concentrations in urine were 0.28 ± 0.38 and 0.30 ± 0.33 μg/L, respectively. Because of the complex nature of milk matrixes, these samples required more dilution before analysis than did urine, thus decreasing the sensitivity of the assay in milk compared with urine. No difference was found in urine glyphosate and AMPA concentrations between subjects consuming organic compared with conventionally grown foods or between women living on or near a farm/ranch and those living in an urban or suburban nonfarming area. CONCLUSIONS Our data provide evidence that glyphosate and AMPA are not detectable in milk produced by women living in this region of the US Pacific Northwest. By extension, our results therefore suggest that dietary glyphosate exposure is not a health concern for breastfed infants. This study was registered at clinicaltrials.gov as NCT02670278.
Hysteresis current control of induction motor drives using dSPACE DSP controller

Hysteresis current control is relatively a simple method for PWM technique with comparatively good current loop response. This paper presents the hardware implementation of hysteresis current control for vector controlled induction motor drives using dSPACE DSP. The analysis is focused on the effect of hysteresis bandwidth to the motor current quality. The hysteresis technique is implemented by using MATLAB/Simulink. The software is linked to the hardware by using dSPACE Real-Time Interface. The experimental rig consists of voltage source inverter, current sensor, induction motor equipped with encoder and PMDC motor coupled with resistor bank as a load. The speed response under various operating conditions and load disturbances are presented to evaluate the drive performance. In order to analyze the performance of hysteresis current controller, the size of the hysteresis band are varied and harmonic content within the stator current is measured in terms of Total Harmonic Distortion (THD). Based on the results, the hysteresis bandwidth has no major effect on the speed response but significantly affects the quality of the motor stator current. Therefore, the small hysteresis bandwidth is desired with consideration on the drives limitation.
Next generation sequencing and molecular imaging identify EGFR mutation and amplification in a glioblastoma multiforme patient treated with an EGFR inhibitor: a case report

Epidermal growth factor receptor (EGFR) mutations and amplifications are frequently reported in glioblastoma multiforme (GBM) patients. In this case report, we utilize next-generation sequencing (NGS) and EGFR molecular imaging to investigate intratumoral heterogeneity in a male patient presenting with GBM. Further, we describe the patient's clinical course as well as outcomes of targeted EGFR therapy with erlotinib, an EGFR tyrosine kinase inhibitor (TKI). NGS demonstrated the presence of an EGFR mutation and amplification in our patient. Molecular imaging revealed a heterogeneous expression pattern of EGFR in the frontal and temporal lobes. This patient briefly responded to erlotinib therapy. However, the patient relapsed and died from progressive neurological deterioration. Partial response and acquired secondary resistance may be attributed to intratumoral heterogeneity. Combination of NGS and EGFR molecular imaging may be helpful in understanding intratumoral molecular heterogeneity and may aid in developing individualized GBM treatments, thereby improving outcomes.
EDGE Detection of MRI Images using Mathematical Morphology and Traditional Techniques

Edge detection is the important step in processing of any digital images for improving the information in the picture so that it can be easily understand by human and to make it suitable and readable for any further processing which works on those images. For Computer vision and Image processing systems to interpret an image, they first must be able to detect the edges of each object in the image. Edge representation of an image drastically reduces the amount of data to be processed, yet it retains important information about the shapes of objects in the scene. In this paper, it has been shown that proposed algorithms using Mathematical Morphology and traditional edge detection algorithms perform better than all these operators under almost all scenarios.
