Incentive Pay and Product Market Competition

This paper examines the influence that product market competition has on the use of incentive payment schemes. We use data from a large representative cross-section survey which allows us to control for other influences. We show that the degree of product market competition that an establishment faces has a significantly positive effect on the likelihood that it will use a performance-related pay system. This relates to earlier theoretical results of Holmstrom and Hart among others. Interestingly, this effect holds for non-managers as well as managers. JEL Classification: D21, J33
Validation and Revision of a German Version of the Balanced Measure of Psychological Needs Scale

Abstract. In this study we tested the psychometric properties of a German version of the Balanced Measure of Psychological Needs scale (BMNP; Sheldon & Hilpert, 2012), a questionnaire to assess the degree of fulfillment of the three basic psychological needs for autonomy, competence, and relatedness. In Study 1, 251 participants completed this questionnaire, as well as measures of life satisfaction, self-esteem, depression, loneliness, and personality traits via online assessment. Results indicate that a six-dimensional structure fit the data adequately well. Furthermore, all three needs independently predicted life satisfaction and depression over and above personality traits. Self-esteem was only predicted by relatedness satisfaction and competence dissatisfaction, and loneliness was only predicted by relatedness. In Study 2, we revised the BMPN by replacing one item and largely replicated the results obtained in Study 1. Study 3 showed that the subscales of the BMPN are only moderately stable over 1 we.
Exploring a Proximity-Coupled Co Chain on Pb(110) as a Possible Majorana Platform

Linear chains of magnetic atoms proximity coupled to an s-wave superconductor are predicted to host Majorana zero modes at the chain ends in the presence of strong spin–orbit coupling. Specifically, iron (Fe) chains on Pb(110) have been explored as a possible system to exhibit topological superconductivity and host Majorana zero modes [Nadj-PergeS. et al., Science2014, 346, 602−60725278507]. Here, we study chains of the transition metal cobalt (Co) on Pb(110) and check for topological signatures. Using spin-polarized scanning tunneling spectroscopy, we resolve ferromagnetic order in the d bands of the chains. Interestingly, also the subgap Yu–Shiba–Rusinov (YSR) bands carry a spin polarization as was predicted decades ago. Superconducting tips allow us to resolve further details of the YSR bands and in particular resonances at zero energy. We map the spatial distribution of the zero-energy signal and find it delocalized along the chain. Hence, despite the ferromagnetic coupling within the chains and the strong spin-orbit coupling in the superconductor, we do not find clear evidence of Majorana modes. Simple tight-binding calculations suggest that the spin–orbit–split bands may cross the Fermi level four times which suppresses the zero-energy modes.
Which exercise prescriptions improve quality of life and physical function in patients with cancer during and following treatment? A systematic review and meta-analysis of randomised controlled trials

Objective Certain exercise prescriptions for patients with cancer may improve self-reported quality of life (QoL) and self-reported physical function (PF). We investigated the effects of exercise on QoL and PF in patients with cancer and studied differences in effects between different intervention-related and exercise-related characteristics. Design We searched four electronic databases to identify randomised controlled trials investigating exercise effects on QoL and PF in patients with cancer. Pooled effects (Hedges’ g) were calculated using Comprehensive Meta-Analysis software. Subgroup analyses were conducted based on intervention dimensions, including timing, duration and delivery mode, and exercise dimensions, including frequency, intensity, type and time (FITT factors). Results We included 74 exercise arms. Patients who were randomised to exercise interventions had significantly improved QoL (g=0.15, 95% CI (0.10 to 0.20), n=67 exercise arms) and PF (g=0.21, 95% CI (0.15 to 0.27), n=59 exercise arms) compared with patients in control groups. We found a significant between-group difference for exercise delivery mode, with significant beneficial effects for supervised exercise interventions (g=0.20, 95% CI (0.14 to 0.26) for QoL and g=0.27, 95% CI (0.20 to 0.33) for PF), but not for unsupervised interventions (g=0.04, 95% CI (−0.06 to 0.13) for QoL and g=0.09, 95% CI (−0.01 to 0.19) for PF). No statistically significant differences in intervention effects were found for variations in intervention timing, duration or exercise FITT factors. Unsupervised exercise with higher weekly energy expenditure was more effective than unsupervised exercise with lower energy expenditure (z=2.34, p=0.02). Conclusions Exercise interventions, especially when supervised, have statistically significant and small clinical benefit on self-reported QoL and PF in patients with cancer. Unsupervised exercise intervention effects on PF were larger when prescribed at a higher weekly energy expenditure.
The differences in intestinal viscosity produced by barley and beta-glucanase alter digesta enzyme activities and ileal nutrient digestibilities more in broiler chicks than in cocks.

The objectives of this study were to determine whether intestinal viscosity caused by mixed linked barley beta-glucan depresses ileal nutrient digestibility and digestive enzyme activities and to determine the interaction of intestinal viscosity, digestive enzyme activities and ileal nutrient digestibility in different ages of poultry. In Experiments 1 and 2, 1-d-old broiler chicks and 1-y-old cocks, respectively, were fed diets with 60% corn, low and high viscosity barley with or without beta-glucanase, for 3 wk. A 3 x 2 factorial design was used. Comparisons were made only within the same age group. In Experiment 3, 1-d-old broiler chicks were fed high viscosity barley with and without beta-glucanase to measure fecal nutrient and ileal and fecal amino acid digestibility. Broiler chicks fed barley ate less and gained less weight than those fed corn; added beta-glucanase resulted in increases in both food consumption and weight gain for the barley-fed chicks (P < 0.05). Relative pancreas weight was higher (P < 0.05) in chicks fed barley than in those fed corn, and lower with beta-glucanase (P < 0.05). Digesta from barley-fed birds had the highest viscosities, which were decreased (P < 0.05) by beta-glucanase. Amylase and lipase were lower in broiler chicks fed high viscosity barley compared with corn (P < 0.05), and beta-glucanase increased both activities and that of trypsin as well (P < 0.05).

Dietary fiber intake in relation to coronary heart disease and all-cause mortality over 40 y: the Zutphen Study.

BACKGROUND Little is known about the effects of dietary fiber intake on long-term mortality. OBJECTIVE We aimed to study recent and long-term dietary fiber intake in relation to coronary heart disease and all-cause mortality. DESIGN The effects of recent and long-term dietary fiber intakes on mortality were investigated in the Zutphen Study, a cohort of 1,373 men born between 1900 and 1920 and examined repeatedly between 1960 and 2000. During that period, 1,130 men died, 348 as a result of coronary heart disease. Hazard ratios were obtained from time-dependent Cox regression models. RESULTS Every additional 10 g of recent dietary fiber intake per day reduced coronary heart disease mortality by 17% (95% CI: 2%, 30%) and all-cause mortality by 9% (0%, 18%). The strength of the association between long-term dietary fiber intake and all-cause mortality decreased from age 50 y (hazard ratio: 0.71; 95% CI: 0.55, 0.93) until age 80 y (0.99; 0.87, 1.12). We observed no clear associations for different types of dietary fiber. CONCLUSIONS A higher recent dietary fiber intake was associated with a lower risk of both coronary heart disease and all-cause mortality. For long-term intake, the strength of the association between dietary fiber and all-cause mortality decreased with increasing age.
Good Semi-supervised Learning That Requires a Bad GAN

Semi-supervised learning methods based on generative adversarial networks (GANs) obtained strong empirical results, but it is not clear 1) how the discriminator benefits from joint training with a generator, and 2) why good semi-supervised classification performance and a good generator cannot be obtained at the same time. Theoretically, we show that given the discriminator objective, good semisupervised learning indeed requires a bad generator, and propose the definition of a preferred generator. Empirically, we derive a novel formulation based on our analysis that substantially improves over feature matching GANs, obtaining state-of-the-art results on multiple benchmark datasets.
Demographics and Psychological Factors Associated with Adiposity in Nurses

Adiposity-based chronic disease (ABCD), overweight-Ow- or obesity-Ob-) in health personnel is as frequent as in the general population, even though they understand well the importance of maintaining a healthy weight. Thus, it is highly likely that certain demographic and psychological conditions, independently of knowledge, are contributing to develop ABCD. The aim of this study was to examine the association between these factors and ABCD in nurses. Data were collected from a cross-sectional study conducted in a tertiary level institute in Mexico City from 2012 to 2013. All the nurses of the institute of any age, shift, service area and seniority were invited to participate and 55% (265) accepted. We found that ABCD was present in 79.6%, and low self-esteem and emotional distress in 26% and 10%, respectively. Working in the night shift (p = 0.031), labor seniority ≥15 years (p = 0.006), having 1 or more children (p = 0.021) and sessions of physical activity <30 min (p = 0.03) were associated with ABCD. Low self-esteem (OR = 2, 95% CI 1.150–3.07, p = 0.023) and emotional distress (OR = 4, 95% CI 1.472–13.078, p = 0.012) were associated with unhealthy lifestyle (less of 3 days per week and/or less of 30 min per session of physical activity and poor dietary habits). Therefore, strategies to prevent and treat ABCD must consider each context among nurses and psychological disorders need be identified to avoid an unhealthy lifestyle.
Comparative Evaluation of the Effect of a Herbal Dentifrice and a Regular Dentifrice on Beneficial Oral Microflora - A Clinico- Microbiologic Study

Background and Objectives Herbal dentifrices are fast gaining popularity in most parts of Asia and Europe. Although effects of dentifrices on pathogenic plaque microorganisms has been documented, little or no evidence exists with regard to their effects on the useful microflora, which help to keep the pathogenic strains at bay. The present study was attempted to evaluate and compare these effects of herbal and conventional dentifrice. Methods 60 student participants in the age group of 18 to 28 years with good oral hygiene (OHI score = 0) were randomly divided into two groups, test and control. The test group used herbal dentifrice and the control group, a regular dentifrice. Plaque and saliva samples were collected at baseline, immediately after brushing, 12 hours after brushing, at 1 week and at 1 month, and cultured. The Streptococcus mitis and Lactobacillus counts along with total microbial counts were estimated at the various time intervals. Results Day 1 showed no significant difference between test and control groups with regard to Streptococcus mitis and Lactobacillus counts as well as total CFU (P>0.05), but at one week control group showed significant increase in streptococcus count in plaque and saliva(P>0.01). Whereas, the test group showed significant increase in L. bacillus and total CFU count in saliva, 12 hrs after brushing, when evaluated at one month (p>0.01). Conclusion Herbal dentifrices may be slightly more effective in preservation of beneficial oral microflora when compared to regular dentifrices, although both are equally effective in inhibiting the pathogenic microorganisms.
Reduction of the radiofrequency heating of metallic devices using a dual‐drive birdcage coil

In this work, it is demonstrated that a dual‐drive birdcage coil can be used to reduce the radiofrequency heating of metallic devices during magnetic resonance imaging. By controlling the excitation currents of the two channels of a birdcage coil, the radiofrequency current that is induced near the lead tip could be set to zero. To monitor the current, the image artifacts near the lead tips were measured. The electric field distribution was controlled using a dual‐drive birdcage coil. With this method, the lead currents and the lead tip temperatures were reduced substantially [<0.3°C for an applied 4.4 W/kg SAR compared to >4.9°C using quadrature excitation], as demonstrated by phantom and animal experiments. The homogeneity of the flip angle distribution was preserved, as shown by volunteer experiments. The normalized root‐mean‐square error of the flip angle distribution was less than 10% for all excitations. The average specific absorption rate increased as a trade‐off for using different excitation patterns. Magn Reson Med, 2013. © 2012 Wiley Periodicals, Inc.
Spatial Rice Yield Estimation Based on MODIS and Sentinel-1 SAR Data and ORYZA Crop Growth Model

Crop insurance is a viable solution to reduce the vulnerability of smallholder farmers to risks from pest and disease outbreaks, extreme weather events, and market shocks that threaten their household food and income security. In developing and emerging countries, the implementation of area yield-based insurance, the form of crop insurance preferred by clients and industry, is constrained by the limited availability of detailed historical yield records. Remote-sensing technology can help to fill this gap by providing an unbiased and replicable source of the needed data. This study is dedicated to demonstrating and validating the methodology of remote sensing and crop growth model-based rice yield estimation with the intention of historical yield data generation for application in crop insurance. The developed system combines MODIS and SAR-based remote-sensing data to generate spatially explicit inputs for rice using a crop growth model. MODIS reflectance data were used to generate multitemporal LAI maps using the inverted Radiative Transfer Model (RTM). SAR data were used to generate rice area maps using MAPScape-RICE to mask LAI map products for further processing, including smoothing with logistic function and running yield simulation using the ORYZA crop growth model facilitated by the Rice Yield Estimation System (Rice-YES). Results from this study indicate that the approach of assimilating MODIS and SAR data into a crop growth model can generate well-adjusted yield estimates that adequately describe spatial yield distribution in the study area while reliably replicating official yield data with root mean square error, RMSE, of 0.30 and 0.46 t ha−1 (normalized root mean square error, NRMSE of 5% and 8%) for the 2016 spring and summer seasons, respectively, in the Red River Delta of Vietnam, as evaluated at district level aggregation. The information from remote-sensing technology was also useful for identifying geographic locations with peculiarity in the timing of rice establishment, leaf growth, and yield level, and thus contributing to the spatial targeting of further investigation and interventions needed to reduce yield gaps.
THE RELATIVE IMPORTANCE OF STRENGTH AND POWER QUALITIES TO VERTICAL JUMP HEIGHT OF ELITE BEACH VOLLEYBALL PLAYERS DURING THE COUNTER-MOVEMENT AND SQUAT JUMP

Despite the inclusion of beach volleyball as an Olympic discipline with a fully professional world tour, little research has been published that has examined the physical qualities of internationally competitive athletes. Thirty international-standard beach volleyball athletes (14 male, 16 female) performed countermovement jumps (CMJ) and squat jumps (SJ) on a force platform. Ground reaction force (GRF) was collected from three SJ separated by 30 seconds passive rest, followed by three CMJ separated by 30 seconds passive rest. Significant differences (P<0.01) between male and female groups were found for all measured GRF characteristics of the SJ and CMJ, with the exception of peak rate of force development, relative peak force, power and relative average power for the CMJ test. For centre of mass displacement (jump height) the male mean was 8.33cm greater than the female mean. The strongest positive correlations with female jump height were SJ: Relative Peak Power (r=0.90); CMJ: Relative Average Power (r=0.67) The strongest positive correlations with male jump height were SJ: Relative Peak Power (r=0.94); Male CMJ: Relative Peak Power (r=0.83). No significant difference (P<0.05) was shown between male and female stretch shortening cycle (SSC) performance as examined by a prestretch augmentation and eccentric utilisation ratios for jump height and peak power. The findings of this study suggest that relative peak and average power outputs are factors highly associated with vertical jump height in elite male and female beach volleyball players
Validity and public health implications of maternal perception of the onset of lactation: an international analytical overview.

The main objective of this analytical overview is to assess the validity of maternal perception of the onset of lactation (OL) as an indicator of lactogenesis stage II (LS-II). Prospective studies that assessed OL and/or LS-II [based on test-weighing milk volume (MV) and/or breast milk biomarkers (BMB)] were identified. OL is a clearly defined and easily identified event across cultures, with the overwhelming majority of women being able to report when they experience it. Mean OL ranges from 50 to 73 h postpartum across studies and from 1 to 148 h postpartum within studies. The wide range detected within samples is fully consistent with the wide within sample LS-II variability as determined by BMB or MV. Studies have identified similar risk factors for delayed LS-II, such as labor and delivery stress, primiparity and insulin-dependent diabetes mellitus, regardless of marker used (i.e., OL, MV or BMB). The correlation between OL and MV (r = -0.60) is of similar magnitude to that between OL and BMB (r = 0.50) and that between BMB and MV (r = 0.47-0.69). In conclusion, OL is a valid clinical indicator of LS-II. This has public health relevance because studies have identified delayed OL (i.e., >72 h postpartum) as a risk factor for shorter breastfeeding duration and for greater infant weight loss by d 3 postpartum. Multidisciplinary studies are needed to standardize the definition of OL and to confirm its validity in different sociocultural contexts.
The Origin of Biases in Face Perception

Experience with certain types of faces during the first year of development defines which types of faces are more efficiently recognized later in life. In work described here, we found that infants who learned to recognize six monkey faces individually (i.e., each face was individually labeled) over a 3-month period maintained the ability to discriminate monkey faces. However, infants who learned these same six faces categorically (i.e., all faces were labeled “monkey”) or were simply exposed to these faces (i.e., faces were not labeled) showed a decline in the ability to discriminate monkey faces. These results suggest that experience individuating faces from 6 to 9 months of age, via labeling, critically shapes the perceptual representation that is responsible for later recognition and discrimination of faces.
Quantitative dynamic cardiac 82Rb PET using generalized factor and compartment analyses.

UNLABELLED We have addressed 2 major challenges of (82)Rb cardiac PET, noninvasive estimation of an accurate input function and absolute quantitation of myocardial perfusion, using a generalized form of least-squares factor analysis of dynamic sequences (GFADS) and a novel compartment analysis approach. METHODS Left and right ventricular (LV + RV) time-activity curves (TACs) were generated from 10 rest/stress studies, and 30 myocardial TACs were modeled to cover a range of clinical values. Two-dimensional PET Monte Carlo simulations of the LV, RV, myocardium, and other organs were generated separately and combined using the above TACs to form 30 realistic dynamic (82)Rb studies. LV and RV TACs were estimated by GFADS and used as input to a 2-compartment kinetic analysis that estimates parametric maps of myocardial tissue extraction (k(1)) and egress (k(2)), as well as LV + RV contributions (f(v), r(v)), by orthogonal voxel grouping. In addition, 13 patients were injected with 2.22 +/- 0.19 GBq (60 +/- 5 mCi) of (82)Rb and imaged dynamically for 6 min at rest and during dipyridamole stress. RESULTS In Monte Carlo simulations, GFADS yielded estimates of the 3 factors and corresponding factor images, with average errors of -4.2% +/- 6.3%, 3.5% +/- 4.3%, and 2.0% +/- 5.5% in the LV, RV, and myocardial factor estimates, respectively. The estimates were significantly more accurate and robust to noise than those obtained using TACs based on manually drawn volumes of interest (P < 0.01). The 2-compartment approach yielded accurate k(1), k(2), f(v), and r(v) parametric maps; the average error of estimates of k(1) was 6.8% +/- 3.6%. In all patient studies, our approach yielded robust estimates of k(1), k(2), f(v), and r(v), which correlated very well with the status of the subject and the catheterization results. CONCLUSION Quantitative dynamic (82)Rb PET using generalized factor analysis of dynamic sequences and compartmental modeling yields estimates of parameters of absolute myocardial perfusion and kinetics with errors of <9%.
A follow-up study of nutrient intake, nutritional status, and growth in infants with cow milk allergy fed either a soy formula or an extensively hydrolyzed whey formula.

BACKGROUND Infants with cow milk allergy (CMA) are reported to have reduced growth and special nutritional needs. OBJECTIVE The aim of the present study was to compare nutrient intake, nutritional status, and growth in infants with CMA who were fed either a soy formula or an extensively hydrolyzed whey formula. DESIGN The study group comprised 168 double-blind challenge-proven infants with CMA. Eighty-four of the infants were fed a soy formula (mean starting age: 7.8 mo), and the other 84 infants were fed an extensively hydrolyzed whey formula (mean starting age: 7.5 mo). RESULTS The length (SD score) of the infants was close to the mean Finnish reference growth by age 2 y in both groups. Weight-for-length measurements continued to reach the 50th percentile by age 4 y in both study groups. The mean nutrient intake followed the recommended intake in both groups, although most of the infants were supplemented with calcium and vitamin D. The observed serum transferrin receptor concentrations indicated a greater iron inadequacy in the tissue of infants in the soy formula group than in the hydrolyzed whey formula group (P = 0.08). However, there were no significant differences between the groups either in the percentages of abnormally low laboratory values (mean cell volume, hemoglobin, zinc, and ferritin) or in the percentages of high alkaline phosphatase activity, which indicates the comparable safety and effectiveness of the formulas studied. CONCLUSIONS Both nutritional status and growth were well within reference values in the 2 groups, and the selection of a formula can largely be made on the basis of infant tolerance to the formulas.
