“I (might be) just that good”: Honest and deceptive impression management in employment interviews
Authors: Bourdage Joshua S. , Roulin Nicolas , Tarraf Rima 
Published: June 2018

AbstractApplicant use of impression management (IM) tactics plays a central role in employment interviews. IM includes behaviors intended to create an impression of competence and likability, and avoid negative impressions. Applicants can influence interviewers’ impressions using both honest and deceptive IM, but measurement of IM has yet to distinguish these two constructs. The goal of the present research was to develop a self‐report Honest Interview Impression Management (HIIM) measure and use this to investigate differential antecedents and consequences of honest and deceptive IM. We report the results of five independent studies (total N = 1,470 interviewees). Studies 1–3 detail the creation of a self‐report measure of honest IM. Studies 4 and 5 utilize this measure to understand the relations between honest and deceptive IM, and their antecedents and consequences. Results demonstrate that honest and deceptive IM are positively related but distinct constructs that have unique antecedents (i.e., age, individual differences, attitudes, situational, and target characteristics) and differentially impact interview outcomes and ratings. Finally, we present a short measure of honest and deceptive IM to be used for time‐sensitive data collection.
Hemodialysis‐related amyloidosis: Is it still relevant?
Authors: Kaneko Shuzo , Yamagata Kunihiro 
Published: June 2018

AbstractAccumulation of amyloid fibrils from β2‐microglobulin (β2M) was first recognized as a characteristic osteoarticular complication in long‐term hemodialysis (HD) patients and called “HD‐related amyloidosis” (HRA). However, this syndrome can also be observed in end‐stage renal diseases (ESRD) patients undergoing peritoneal dialysis, and even in patients with chronic renal failure before the initiation of dialytic therapy, suggesting that HD is not a direct cause but that accumulation of β2M or some β2M‐associated molecules in the body is a common pathogenesis. Currently the term “dialysis‐related amyloidosis” (DRA) is widely used for β2M‐amyloid (Aβ2M) amyloidosis associated with ESRD, although DRA patients consist mostly of those undergoing long‐term HD. Factors other than β2M accumulation also play a role in the formation/local deposition of Aβ2M and disruption of tissue architecture. Conformational changes of β2M by misfolding/unfolding, and promoting/inhibitory effects induced by other coexisting molecules, advanced glycation and oxidation, and direct cell toxicity have also been documented. Two technological improvements of HD have been the keys to prevent the development and progression of DRA: the efficient removal of β2M by using high‐flux membranes, high‐volume convection and adsorptive column/membrane, as well as the use of biocompatible membranes and dialysates (eg, ultrapure and acetate‐free dialysates) have minimized both inflammation and β2M production. Epidemiologically, a decrease in the incidence of DRA has recently been reported; however, longer survival of HD patients may contribute to the development of more DRA, though with a delayed onset. In this article, we describe the pathogenesis of DRA, the strategies developed for its prevention and minimization, and the favorable epidemiological data achieved by these efforts.
Double bridge circuit for self‐validated structural health monitoring strain measurements
Authors: dos Reis J. , Oliveira Costa C. , Sá da Costa J. 
Published: June 2018

AbstractIn structural health monitoring (SHM) applications, sensor faults and structural damage need to be assuredly discriminated. A self‐diagnosis strain sensor operating in a continuous online SHM scenario is considered. The strain sensor is based on full electric resistance strain gauge Wheatstone bridges. The state of the art shows that such a sensor has not yet been developed. The loop current step response (LCSR) is a well‐known method to detect strain gauge debonding. However, applying the LCSR method to a full strain gauge Wheatstone bridge has some limitations analysed in this paper. To enable the use of the LCSR method in an online SHM scenario, the double bridge circuit is proposed in this work. Two new strain gauge debonding fault detection methods and a new debonding fault isolation method—based on the double bridge circuit measurements—are proposed and evaluated. Two new sensor fusion weighting approaches are also proposed and evaluated—to achieve strain gauge debonding fault tolerance on the double bridge circuit. The experimental results show that the proposed methods can detect, isolate, and tolerate a strain gauge grid debonding fault and can be applied in an online SHM self‐diagnosis sensor scenario.

Published: June 2018

AbstractObjectiveTo evaluate whether cell‐free DNA (cfDNA) concentrations are increased in dogs with exertional rhabdomyolysis and whether concentrations are correlated with serum myoglobin concentration and creatine kinase activity.DesignObservational cohort study.SettingYukon Quest 1,000‐mile International Sled Dog Race 2015.AnimalsTwelve normal competitive sled dogs; 5 dogs with rhabdomyolysis.InterventionsNone.Measurements and Main ResultsBlood was collected from all confirmed cases of exertional rhabdomyolysis and compared to the winning team at the midrace point. Results indicate that median cfDNA did not increase, but decreased by the race finish (prerace = 314.2 ng/mL versus midrace = 283.7 ng/mL versus postrace = 249.5 ng/mL). There were no rises in median cfDNA in dogs with rhabdomyolysis (255 ng/mL) negating its potential utility as a measure of acute skeletal muscle compromise. In contrast, myoglobin concentration and creatine kinase activity at the midrace point for normal dogs were significantly lower than dogs with rhabdomyolysis. Values for myoglobin and creatine kinase were strongly positively correlated (R = 0.91).ConclusionscfDNA is not a useful biomarker for exertional rhabdomyolysis in contrast to myoglobin and creatine kinase. Further evaluation of timing and clinical signs suggests that exertional rhabdomyolysis occurs early in endurance activities. Among the dogs with rhabdomyolysis, the dog that demonstrated clinical signs had the highest serum creatine kinase activity and myoglobin concentration.
Economic Uncertainty and Money Demand Stability in Uganda during Financial Liberalization: A GARCH and ARDL Approach
Authors: Kayongo Allan , Guloba Asumani 
Published: June 2018

This paper examines the impact of economic uncertainty on money demand stability in Uganda during financial liberalization. First, an economic uncertainty index is created using the Generalized autoregressive conditional heteroscedasticity method to measure uncertainty. Secondly, the Autoregressive Distributed Lag methodology is used to estimate three risk-augmented monetary aggregates: base money, broad money and broad money . The results show that economic uncertainty has no effect on real base money and real broad money in the short run; but has a negative effect on real broad money . However, economic uncertainty negatively affects all monetary aggregates after one quarter. This is because economic agents diversify their portfolio from just holding money, into other forms like: long term accounts; foreign accounts; treasury bills and bonds; property; mortgages and land. The three money demand balances are also stable.

IntroductionThe incidence of depression is high during the perinatal period. This mood disorder can have a significant impact on the mother, the child and the family.ObjectiveTo examine the effect of an exercise programme during pregnancy on the risk of perinatal depression.MethodsHealthy women who were <16 weeks pregnant were randomly assigned to two different groups. Women in the intervention group participated in a 60 min exercise programme throughout pregnancy, 3 days per week, which was conducted from October 2014 to December 2016. The Center for Epidemiological Studies-Depression Scale was used to measure the risk of depression at the beginning of the study (12–16 weeks), at gestational week 38 and at 6 weeks postpartum.ResultsOne hundred and twenty-four pregnant women were allocated to either the intervention (IG=70) or the control (CG=54) group. No differences were found in the percentage of depressed women at baseline (20% vs 18.5%) (χ2=0.043; p=0.836). A smaller percentage of depressed women were identified in the IG compared with the CG at 38 gestational weeks (18.6% vs 35.6%) (χ2=4.190; p=0.041) and at 6 weeks postpartum (14.5% vs 29.8%) (χ2=3.985; p=0.046) using the per-protocol analysis. No significant differences were found using the intention-to-treat analyses, except in the multiple imputation analysis at week 38 (18.6% vs 34.4%) (χ2=4.085; p=0.049).ConclusionAn exercise programme performed during pregnancy may reduce the prevalence of depression in late pregnancy and postpartum.Trial registration numberNCT02420288; Results.

ObjectivesTo estimate the frequency of patient-perceived potentially harmful problems occurring in primary care. To describe the type of problem, patient predictors of perceiving a problem, the primary care service involved, how the problem was discussed and patient suggestions as to how the problem might have been prevented. To describe clinician/public opinions regarding the likelihood that the patient-described scenario is potentially harmful.DesignPopulation-level survey.SettingGreat Britain.ParticipantsA nationally representative sample of 3975 members of the public aged ≥15 years interviewed during April 2016.Main outcome measuresCounts of patient-perceived potentially harmful problems in the last 12 months, descriptions of patient-described scenarios and review by clinicians/members of the public.Results3975 of 3996 participants in a nationally representative survey completed the relevant questions (99.5%). 300 (7.6%; 95% CI 6.7% to 8.4%) of respondents reported experiencing a potentially harmful preventable problem in primary care during the past 12 months and 145 (48%) discussed their concerns within primary care. This did not vary with age, gender or type of service used. A substantial minority (30%) of the patient-perceived problems occurred outside general practice, particularly the dental surgery, walk in clinic, out of hours care and pharmacy. Patients perceiving a potentially harmful preventable problem were eight times more likely to have ‘no confidence and trust in primary care’ compared with ‘yes, definitely’ (OR 7.9; 95% CI 5.9 to 10.7) but those who discussed their perceived-problem appeared to maintain higher trust and confidence. Generally, clinicians ranked the patient-described scenarios as unlikely to be potentially harmful.ConclusionsThis study highlights the importance of actively soliciting patient’s views about preventable harm in primary care as patients frequently perceive potentially harmful preventable problems and make useful suggestions for their prevention. Such engagement may also help to improve confidence and trust in primary care.
An Empirical Study on Software Defect Prediction Using Over-Sampling by SMOTE
Authors: Pak Cholmyong , Wang Tian Tian , Su Xiao Hong 
Published: June 2018

Software defect prediction suffers from the class-imbalance. Solving the class-imbalance is more important for improving the prediction performance. SMOTE is a useful over-sampling method which solves the class-imbalance. In this paper, we study about some problems that faced in software defect prediction using SMOTE algorithm. We perform experiments for investigating how they, the percentage of appended minority class and the number of nearest neighbors, influence the prediction performance, and compare the performance of classifiers. We use paired t-test to test the statistical significance of results. Also, we introduce the effectiveness and ineffectiveness of over-sampling, and evaluation criteria for evaluating if an over-sampling is effective or not. We use those concepts to evaluate the results in accordance with the evaluation criteria for the effectiveness of over-sampling. The results show that they, the percentage of appended minority class and the number of nearest neighbors, influence the prediction performance, and show that the over-sampling by SMOTE is effective in several classifiers.

Delay Scaling in Many-Sources Wireless Networks without Queue State Information
Authors: Borst Sem , Zubeldia Martin 
Published: June 2018

We examine a canonical scenario where several wireless data sources generate sporadic delay-sensitive messages that need to be transmitted to a common access point. The access point operates in a time-slotted fashion, and can instruct the various sources in each slot with what probability to transmit a message, if they have any. When several sources transmit simultaneously, the access point can detect a collision, but is unable to infer the identities of the sources involved. While the access point can use the channel activity observations to obtain estimates of the queue states at the various sources, it does not have any explicit queue length information otherwise.
We explore the achievable delay performance in a regime where the number of sources n grows large while the relative load remains fixed. This scaling is particularly pertinent in Internet of Things (IoT) scenarios, where a key challenge is to achieve low delay when the overall traffic activity is dispersed across massive numbers of highly intermittent sources.

We establish that, under any medium access algorithm without queue state information, the average delay must be at least of the order of n slots when the load exceeds some threshold λ* < 1$. This demonstrates that bounded delay can only be achieved if a positive fraction of the system capacity is sacrificed. Furthermore, we introduce a scalable Two-Phase algorithm for low-delay IoT applications which achieves a delay upper bounded uniformly in n when the load is below e
-1
, and a delay of the order of n slots when the load is between e
-1
and 1. Additionally, this algorithm provides robustness against correlated source activity, which is also prevalent in IoT scenarios.
Distinct cell types in the superficial superior colliculus project to the dorsal lateral geniculate and lateral posterior thalamic nuclei
Authors: Gale Samuel D. , Murphy Gabe J. 
Published: June 2018

The superficial layers of the superior colliculus (sSC) receive retinal input and project to thalamic regions, the dorsal lateral geniculate (dLGN) and lateral posterior (LP; or pulvinar) nuclei, that convey visual information to cortex. A critical step toward understanding the functional impact of sSC neurons on these parallel thalamo-cortical pathways is determining whether different classes of sSC neurons, which are known to respond to different features of visual stimuli, innervate overlapping or distinct thalamic targets. Here, we identified a transgenic mouse line that labels sSC neurons that project to dLGN but not LP. We utilized selective expression of fluorophores and channelrhodopsin in this and previously characterized mouse lines to demonstrate that distinct cell types give rise to sSC projections to dLGN and LP. We further show that the glutamatergic sSC cell type that projects to dLGN also provides input to the sSC cell type that projects to LP. These results clarify the cellular origin of parallel sSC-thalamo-cortical pathways and reveal an interaction between these pathways via local connections within the sSC. NEW & NOTEWORTHY The superficial layers of the superior colliculus (sSC) project to two visual thalamic targets: the dorsal lateral geniculate (dLGN) and lateral posterior (LP) nuclei. We show that distinct excitatory sSC cell types give rise to these projections; stellate cells project to dLGN and wide-field (WF) cells project to LP. Moreover, these pathways interact via a connection within the sSC from stellate to WF cells.

The current electrophysiological study investigated the functional roles of high- and low-voltage-activated Ca2+ channel subtypes on glutamatergic small mossy fiber nerve terminals (SMFTs) that synapse onto rat hippocampal CA3 neurons. Experiments combining both the “synapse bouton” preparation and single-pulse focal stimulation technique were performed using the conventional whole cell patch configuration under voltage-clamp conditions. Nifedipine, at a high concentration, and BAY K 8644 inhibited and facilitated the glutamatergic excitatory postsynaptic currents (eEPSCs) that were evoked by 0.2-Hz stimulation, respectively. However, these drugs had no effects on spontaneous EPSCs (sEPSCs). Following the use of a high stimulation frequency of 3 Hz, however, nifedipine markedly inhibited eEPSCs at the low concentration of 0.3 µM. Moreover, ω-conotoxin GVIA and ω-agatoxin IVA significantly inhibited both sEPSCs and eEPSCs. Furthermore, SNX-482 slightly inhibited eEPSCs. R(−)-efonidipine had no effects on either sEPSCs or eEPSCs. It was concluded that glutamate release from SMFTs depends largely on Ca2+ entry through N- and P/Q-type Ca2+ channels and, to a lesser extent, on R-type Ca2+ channels. The contribution of L-type Ca2+ channels to eEPSCs was small at low-firing SMFTs but more significant at high-firing SMFTs. T-type Ca2+ channels did not appear to be involved in neurotransmission at SMFTs. NEW & NOTEWORTHY Action potential-evoked glutamate release from small mossy fiber nerve terminals (SMFTs) that synapse onto rat hippocampal CA3 neurons is regulated by high-threshold but not low-threshold Ca2+ channel subtypes. The functional contribution mainly depends on N- and P/Q-type Ca2+ channels and, to a lesser extent, on R-type Ca2+ channels. However, in SMFTs stimulated at a high 3-Hz frequency, L-type Ca2+ channels contributed significantly to the currents. The present results are consistent with previous findings from fluorometric studies of large mossy fiber boutons.

Published: June 2018

Speed modulation requires spatiotemporal adjustments and altered neural drive to different muscles. The loss of certain muscles produces changes in the locomotor pattern and functional compensation. However, how the loss of specific muscles affects speed modulation has not been specifically investigated. Here, we denervated the lateral gastrocnemius and soleus muscles unilaterally in seven cats that had recovered hindlimb locomotion following complete spinal transection (spinal cats). Hindlimb locomotion was tested at 10 speeds, from 0.1 to 1.0 m/s, before, 1–2 days, and 1–8 wk after denervation. Six of seven cats performed hindlimb locomotion 1–2 days postdenervation at all speeds, with the exception of two out of those six cats that did not perform stable stepping at 0.9 and 1.0 m/s. All seven cats performed hindlimb locomotion 1–8 wk postdenervation at all speeds. In some cats, at 1–2 days postdenervation, the ipsilateral hindlimb performed more steps than the contralateral hindlimb, particularly at slow speeds. This 2:1 coordination disappeared over time. In three cats, the linear increase in the amplitude of the electromyography of the ipsilateral medial gastrocnemius was reduced with increasing speed early after denervation before recovering later on. Overall, the results indicate that spinal circuits interacting with sensory feedback from the hindlimbs compensate for the partial loss of ankle extensors, retaining the ability to modulate locomotor speed. NEW & NOTEWORTHY We investigated speed modulation after denervating 2 ankle extensors unilaterally at 10 treadmill speeds in spinal-transected cats. Although we observed new forms of left-right coordination and changes in muscle activity of a remaining synergist, modulation of spatiotemporal variables with increasing speed was largely maintained after denervation. The results indicate that spinal locomotor centers interacting with sensory feedback compensate for the loss of ankle extensors, allowing speed modulation.
