Published: July 2017

PurposeThe purpose of this paper is to identify the arbitrage opportunities between US industry-level credit and stock markets with a focus on dynamic lead-lag relationships given that these markets involve heterogeneous agents operating over various time horizons.Design/methodology/approachThe authors use daily data of 11 US industries stock markets and their credit counterparts to model the dynamic dependence and casual nexuses using time-frequency approach, namely, wavelet squared coherence (WTC).FindingsThe WTC estimation results show that credit and stock markets are out of phase (counter cyclical) and stock markets lead their credit counterparts. The coherence between two markets increases during financial crises. The banks (utilities) industry credit and stock markets have relatively high (low) dependence.Research limitations/implicationsThe casual nexuses between stock and credit markets have multilateral dimensions. Greater interest in examining the relationship between stock markets and credit default swap (CDS) spreads emerged as an important albeit a complex area of research, and gained prominence especially at the onset and following the global financial crises of 2007-2008 which clearly showed that the positive views of CDSs contribution in creating a resilient and efficient financial sector was nothing further from the truth.Practical implicationsThe arbitrage and hedging opportunities between stock and credit markets are industry dependent and vary over investment time horizons. The utilities industry seems attractive for the investment with the objective to exploit arbitrage, but not for hedging.Originality/valueThe paper, for the first time, employs time-frequency approach to assess the arbitrage opportunities between US industry-level credit and stock markets.
Mindfulness as substitute for transformational leadership
Authors: Kroon Brigitte , van Woerkom Marianne , Menting Charlotte 
Published: July 2017

PurposeTransformational leaders spark the intrinsic motivation of employees, thereby stimulating their extra-role performance. However, not all employees are lucky enough to have a transformational leader. The purpose of this paper is to investigate to what extent mindfulness can function as a substitute for transformational leadership. By being attentive to and aware of what is taking place in the present, mindfulness provides employees with a source of intrinsic motivation that lies within the person, thereby possibly making employees less dependent on transformational leadership.Design/methodology/approachAn online survey was used to collect data of 382 employees working in diverse sectors in the Netherlands.FindingsModerated mediation analyses indicated that mindfulness partly compensates for a low levels of transformational leadership in fostering intrinsic motivation and in turn extra-role performance, thereby providing evidence for the substitutes for leadership theory. Moreover, the findings extend previous research on the contribution of mindfulness to in-role performance by showing its additional value for intrinsic motivation and extra-role performance.Research limitations/implicationsDespite the use of validated measures and the presence of an interaction effect, common-source bias cannot be out ruled completely.Practical implicationsSince mindfulness can be developed, the results suggest a training intervention to make employees less dependent on their leaders for their motivation.Originality/valueThis paper is the first to show that mindful people are more resilient against the absence of transformational leadership. Given the frequent changes in management layers in organizations, knowledge about resources for individual resilience and self-management is sorely needed.
Effect of layer thickness on irreversible thermal expansion and interlayer strength in fused deposition modeling
Authors: D’Amico Anthony A. , Debaie Analise , Peterson Amy M. 
Published: July 2017

Purpose
The aim of this paper is to examine the impact of layer thickness on irreversible thermal expansion, residual stress and mechanical properties of additively manufactured parts.

Design/methodology/approach
Samples were printed at several layer thicknesses, and their irreversible thermal expansion, tensile strength and flexural strength were determined.

Findings
Irreversible thermal strain increases with decreasing layer thickness, up to 22 per cent strain. Tensile and flexural strengths exhibited a peak at a layer thickness of 200 μm although the maximum was not statistically significant at a 95 per cent confidence interval. Tensile strength was 54 to 97 per cent of reported values for injection molded acrylonitrile butadiene styrene (ABS) and 29 to 73 per cent of those reported for bulk ABS. Flexural strength was 18 to 41 per cent of reported flexural strength for bulk ABS.

Practical implications
The large irreversible thermal strain exhibited that corresponding residual stresses could lead to failure of additively manufactured parts over time. Additionally, the observed irreversible thermal strains could enable thermally responsive shape in additively manufactured parts. Variation in mechanical properties with layer thickness will also affect manufactured parts.

Originality/value
Tailorable irreversible thermal strain of this magnitude has not been previously reported for additively manufactured parts. This strain occurs in parts made with both high-end and consumer grade fused deposition modeling machines. Additionally, the impact of layer thickness on tensile and flexural properties of additively manufactured parts has received limited attention in the literature.

AbstractSacran, a polysaccharide isolated from Aphanothece sacrum (Suizenji‐nori) alga, has unique characteristics in terms of its physiological properties and effects on the skin, and has recently become a focus of attention as a novel biomaterial. In a previous study, we reported the unique physical characteristics of sacran, which forms a gel‐like film containing water in the presence of polyols. This film resists penetration by water and chemicals. We expected this unique physical characteristic to act as an artificial barrier upon the application of sacran to the skin. In the present study, we tested the efficacy of sacran application in healthy individuals who reported previous symptoms of dry or inflamed skin, to evaluate the potential benefits of sacran for skin care in patients with mild atopic dermatitis. Compared with placebo, sacran‐containing serum did not significantly alter either the water content of the skin surface or transepidermal water loss. However, subjects using the serum showed improvements in corneocyte parameters including size, percentage of thick abrasion, ratio of SH to SS groups, ratio of interleukin (IL)‐1 receptor antagonist to IL‐1α, and carbonylated protein level. These results indicate that the sulfated polysaccharide sacran is an effective agent for improving or maintaining the skin conditions.
Full waveform inversion using oriented time‐domain imaging method for vertical transverse isotropic media
Authors: Zhang Zhen‐dong , Alkhalifah Tariq 
Published: July 2017

ABSTRACTFull waveform inversion for reflection events is limited by its linearised update requirements given by a process equivalent to migration. Unless the background velocity model is reasonably accurate, the resulting gradient can have an inaccurate update direction leading the inversion to converge what we refer to as local minima of the objective function. In our approach, we consider mild lateral variation in the model and, thus, use a gradient given by the oriented time‐domain imaging method. Specifically, we apply the oriented time‐domain imaging on the data residual to obtain the geometrical features of the velocity perturbation. After updating the model in the time domain, we convert the perturbation from the time domain to depth using the average velocity. Considering density is constant, we can expand the conventional 1D impedance inversion method to two‐dimensional or three‐dimensional velocity inversion within the process of full waveform inversion. This method is not only capable of inverting for velocity, but it is also capable of retrieving anisotropic parameters relying on linearised representations of the reflection response. To eliminate the crosstalk artifacts between different parameters, we utilise what we consider being an optimal parametrisation for this step. To do so, we extend the prestack time‐domain migration image in incident angle dimension to incorporate angular dependence needed by the multiparameter inversion. For simple models, this approach provides an efficient and stable way to do full waveform inversion or modified seismic inversion and makes the anisotropic inversion more practicable. The proposed method still needs kinematically accurate initial models since it only recovers the high‐wavenumber part as conventional full waveform inversion method does. Results on synthetic data of isotropic and anisotropic cases illustrate the benefits and limitations of this method.

Published: July 2017

AbstractDetection of aged fingerprints is difficult because they can degrade over time with exposure to light, moisture, and temperature. In this study, aging fingerprints were visualized by time‐resolved spectroscopy with an ultraviolet‐pulsed laser. Fingerprints were prepared on glass slides and paper and then stored under three lighting conditions and two humidity conditions for up to a year. The fluorescence intensities of the fingerprints decreased with time. Samples were stored in the dark degraded less than in sunlight or under a fluorescent lamp. Samples were stored under low humidity degraded less than under moderate humidity. As the storage period increased, a fluorescence emission peak appeared that was at a longer wavelength than the peak visible in earlier spectra. This peak was used for visualization of an aged fingerprint over time. An image of the fingerprint was not initially visible, but an image appeared as the time since deposition of the fingerprint increased.

ObjectiveThe 11th version of the International Classification of Diseases (ICD‐11) has proposed two related trauma diagnoses: Post‐traumatic stress disorder (PTSD) and ComplexPTSD(CPTSD). Using a newly developed, disorder‐specific measure ofPTSDandCPTSDcalled theInternational Trauma Questionnaire(ITQ) the current study will (i) assess the factorial validity ofICD‐11PTSDandCPTSD; (ii) provide the first test of the discriminant validity of these constructs; and (iii) provide the first comparison ofICD‐11, and Diagnostic and Statistical Manual, Fifth Edition (DSM‐5),PTSDdiagnostic rates using disorder‐specific measures.MethodICD‐11 andDSM‐5PTSD‐specific measures were completed by a British clinical sample of trauma‐exposed patients (N =171). The structure and validity ofICD‐11PTSDandCPTSDwere assessed by means of factor analysis and assessing relationships with criterion variables.ResultsDiagnostic rates underICD‐11 were significantly lower than those underDSM‐5. A two‐factor second‐order model reflecting the distinction betweenPTSDandCPTSDbest represented the data from theITQ; and thePTSDandCPTSDfactors differentially predicted multiple psychological variables.ConclusionThe factorial and discriminant validity ofICD‐11PTSDandCPTSDwas supported, andICD‐11 produces fewer diagnostic cases thanDSM‐5.
Electoral Ambiguity and Political Representation
Authors: Kartik Navin , Van Weelden Richard , Wolton Stephane 
Published: July 2017

AbstractWe introduce a Downsian model in which policy‐relevant information is revealed to the elected politician after the election. The electorate benefits from giving the elected politician discretion to adapt policies to his information. But limits on discretion are desirable when politicians do not share the electorate's policy preferences. Optimal political representation generally consists of a mixture of the delegate (no discretion) and trustee (full discretion) models. Ambiguous electoral platforms are essential for achieving beneficial representation. Nevertheless, electoral competition does not ensure optimal representation: The winning candidate's platform is generally overly ambiguous. While our theory rationalizes a positive correlation between ambiguity and electoral success, it shows that the relationship need not be causal.
Measurement centration and zone diameter in anterior, posterior and total corneal astigmatism in keratoconus
Authors: Fredriksson Anneli , Behndig Anders 
Published: July 2017

AbstractPurposeTo investigate the central and paracentral astigmatism and the significance of centration and measurement zone diameter compared to a 3‐mm pupil‐centred measurement zone in keratoconus and in healthy eyes.MethodsTwenty‐eight right eyes from 28 KC patients with an inferotemporal cone were selected according to specified criteria based on Oculus Pentacam HR® measurements and were matched with healthy control eyes. The flat (K1) and steep (K2) keratometry readings were registered from the ‘Total Corneal Refractive Power’ (TCRP) display as well as the anterior and posterior corneal astigmatism displays (ACA and PCA, respectively). Astigmatic power vectors KP0 and KP45 were calculated and analysed for a 6‐mm and two 3‐mm zones centred on the corneal apex and the pupil, and for 8 paracentral 3‐mm zones.ResultsThe astigmatism was generally higher in KC. Many astigmatic values in KC differed between the 3‐mm pupil‐centred and the 3‐ and 6‐mm apex‐centred zones in KC. In the controls, no corresponding differences between measurement zones were seen, apart from PCA, which differed. The magnitude and direction of KP0 and KP45 varied greatly between the paracentral measurements in KC.ConclusionCentration and measurement zone diameter have great impacts on the astigmatic values in KC. A small pupil‐centred measurement zone should be considered when evaluating the astigmatism in KC.

AbstractAimThis study examines parental satisfaction with care received in the context of a life‐limiting foetal diagnosis and subsequent birth.MethodsSurvey methods were utilised to embed the Quality Indicators (QI) and Parental Satisfaction of Perinatal Palliative Care Instrument in a survey: ‘The Voice of Parents’.ResultsThe web‐based survey had a final sample of N = 405 parent responders. Overall, parents reported satisfaction with care (80.2%; n = 393). Parents satisfied with care reported higher agreement with quality indicator items for all subscales. In total, 17 items from the 41‐item instrument revealed the ability to predict higher parental satisfaction when particular QI are reported.ConclusionThis study has led to credible insights into parental satisfaction with care given after the birth of an infant with a life‐limiting condition. The findings contribute to development of a model with a good fit in ascertaining the importance of compassion, unhurried provider–patient communication and bereavement interventions.
Neonatal therapeutic hypothermia outside of standard guidelines: a survey of U.S. neonatologists
Authors: Burnsed Jennifer , Zanelli Santina A. 
Published: July 2017

AbstractAimTherapeutic hypothermia is standard of care in term infants with moderate‐to‐severe hypoxic–ischaemic encephalopathy (HIE). The goal of this survey was to explore the attitudes of U.S. neonatologists caring for infants with HIE who fall outside of current guidelines.MethodsCase‐based survey administered to members of the Section on Neonatal‐Perinatal Medicine of the American Academy of Pediatrics.ResultsA total of 447 responses were analysed, a response rate of 19%. We found significant variability amongst U.S. neonatologists with regard to the use of therapeutic hypothermia for infants with HIE who fall outside standard inclusion criteria. Scenarios with the most variability included HIE in a late preterm infant and HIE following a postnatal code. Provision of therapeutic hypothermia outside of standard guidelines was not influenced by number of years in practice, neonatal intensive care type (NICU) or NICU size.ConclusionSignificant variability in practice exists when caring for infants with HIE who do not meet standard inclusion criteria, emphasizing the need for continued and rigorous research in this area.

Published: July 2017

AbstractAimToll‐like receptors (TLR) are innate immunity molecules and our previous studies found that TLR1 gene polymorphism was associated with postbronchiolitis asthma at one to six years of age, as was TLR10 at five to seven years of age. This study examined any associations at 11–13 years of age.MethodsThis prospective follow‐up study was part of an ongoing evaluation of children admitted to Tampere University Hospital, Finland, for bronchiolitis in 2001–2004 at less than six months of age. We evaluated the association of TLR1 rs5743618 and TLR10 rs4129009 polymorphisms with asthma and asthma medication in 125 children aged 11–13 years.ResultsAssociations were measured as adjusted odd ratios (aOR) with 95% confidence intervals (95% CI). The variant TLR1 rs5743618 (aOR 4.04, 95% CI 0.99–13.01) and TLR10 rs4129009 (aOR 7.02, 95% CI 1.56–31.53) genotypes increased the risk of needing inhaled corticosteroids (ICSs) at 11–13 years of age. The variant TLR10 genotype (aOR 7.69, 95% CI 1.35–43.95) increased the risk of persistent asthma continuing from five to seven years of age until 11–13 years of age. The results were similar when the combined genotypes were analysed. [Correction added on 3 October 2017, after online publication: The data in the variant TRL1 rs5743618 genotype were incorrect and have been corrected in this version.]ConclusionPolymorphisms in both the TLR1 and TLR10 genes may increase the risk of asthma at 11–13 years after infant bronchiolitis.
Crotalus atrox Venom Exposed to Carbon Monoxide Has Decreased Fibrinogenolytic Activity In Vivo in Rabbits
Authors: Nielsen Vance G. 
Published: July 2017

AbstractEnvenomation by haemotoxic enzymes remains a significant source of human morbidity and mortality worldwide, with administration of long‐acting or multiple doses of antivenom first‐line therapy. However, coagulopathy can still occur and recur. Of interest, it has been recently demonstrated that direct, isolated exposure of snake venom enzymes with fibrinogenolytic activity to carbon monoxide (CO) abrogates venom‐mediated loss of coagulation in human plasma. These observations of CO inhibition of venom fibrinogenolytic activity were subsequently repeated in rabbit whole blood. This study sought to translate these findings in an in vivo rabbit model of envenomation with fibrinogenolytic Crotalus atrox venom. Sedated rabbits were intravenously administered C. atrox venom (400 μg/kg) pre‐exposed to 0 or 1000 μM carbon monoxide‐releasing molecule‐2 (CORM‐2) in vitro. Arterial whole‐blood samples demonstrated that compared to pre‐envenomation values, the CORM‐2‐naïve venom significantly prolonged the onset of coagulation, decreased the velocity of clot growth and decreased clot strength as determined by thromboelastography an hour after venom injection. In contrast, CORM‐2 pre‐exposure prevented or attenuated C. atrox venom effects on coagulation kinetics. Future studies to determine whether rabbits injected with such venom subcutaneously/intramuscularly can have consequent coagulopathy abrogated by injection of carbon monoxide‐releasing molecules into the ‘bite site’ are justified.

ObjectivesBipolar Disorder (BD) is associated with cognitive impairment even during remission periods. Nonetheless, this impairment seems to adjust to different profiles of severity. Our aim was to examine the potential impact of childhood trauma (CT) on cognitive performance and, more specifically, on neurocognitive profile membership.MethodsUsing a data‐driven strategy, 113 euthymic bipolar patients were grouped according to their cognitive performance using a hierarchical clustering technique. Patients from the three resulting clusters, the so‐called “low”, “average”, and “high performance” groups, were then compared in terms of main sociodemographic, clinical and functioning variables, including CT measures. One‐way ANOVA, a chi‐square test and partial correlations were used for this purpose, as appropriate. A multinomial logistic regression model was used to determine which variables contributed to neurocognitive clustering membership.ResultsPatients from the three neurocognitive clusters differed in terms of sociodemographic, clinical, functioning and CT variables. Scores on the Childhood Trauma Questionnaire (CTQ), especially on the physical negligence subscale, were also associated with a poor cognitive performance. The multinomial regression model indicated that CTQ total scores and the estimated intelligence quotient (IQ) significantly contributed to differentiation among the three neurocognitive groups.ConclusionsOur results confirmed that CT significantly impacts on cognitive performance during adulthood in BD. The data obtained suggest that a history of CT could act as a liability marker for cognitive impairment. A higher estimated IQ may act as a protective factor against cognitive decline in this group of patients.
