Linking social identity, risk perception, and behavioral psychology to understand predator management by livestock producers
Authors: van Eeden Lily M. , Slagle Kristina , Crowther Mathew S. , Dickman Christopher R. , Newsome Thomas M.
Published: February 2020

Human behaviors can determine the success of efforts to restore predators to ecosystems. While behaviors such as lethal predator control may impede predator restoration, other land management practices can facilitate coexistence between predators and humans. Socio‐psychological theories provide useful tools for understanding and improving these human behaviors. We explore three frameworks to understand what shapes Australian livestock graziers' behaviors with regards to management of the threat that dingoes pose to livestock. These frameworks are the theory of reasoned action (incorporating values and beliefs about dingoes), the social identity approach, and perception of risk. We distributed a survey to Australian graziers by mail and online (n = 138) which allowed recording of information on these three frameworks and their engagement in lethal dingo control. Among the respondents, we found that all three frameworks were linked with lethal dingo control when assessed individually, but when combined in a hierarchical regression, only social identity (specifically, identifying as an “environmentalist” or “pest controller”) was significant in predicting behavior. This result reveals the strength of social norms and normative beliefs over perceived risk in shaping behavior. As such, social identity is a useful metric for predicting and understanding environmental management behavior. Determining what these social identities mean in a given context is important for identifying how to implement behavior change to promote evidence‐based management that facilitates restoration of wildlife such as predators to landscapes where conflict with humans occurs.
Power corrupts (or does it?): An examination of the boundary conditions of the antisocial effects of experienced power
Authors: Foulk Trevor A. , Chighizola Nicolais , Chen Gilad
Published: February 2020

One of the most common conclusions in the power literature is that when people feel powerful, they behave in selfish and antisocial ways. While this conclusion tends to permeate the literature, research also recognizes that there are factors that can mitigate the corrupting nature of power, and that the experience of power may also lead to more positive and prosocial outcomes. In this article, we review findings that illustrate how individual differences, the contexts in which people experience power, and their construal of power all help determine how powerful people will ultimately behave toward others. We then consider these findings in totality, and suggest that they may articulate a more complex conceptualization of power as it relates to social behaviors. Specifically, we suggest considering not only the amount of power one has but also focusing on the way individuals experience power may provide a way to reconcile the disparate findings in the social power literature. We argue that research should expand upon the possible dualistic nature of power, and how the existence of both positive and negative construals of power can influence behaviors.

Published: February 2020

Youth of today face a very challenging era. The excellent education provided to them will shape them into individuals with an excellent personality, where they can be the apprentice of good behaviour generation. However, the increase of misconduct amongst teenagers is reported to indirectly affect the role of parents as a main social agent. These social agents can contribute to the development of teenagers’ personality. Al Quran, as Manhaj Rabbani, provides solutions and guidance in shaping the personality of children and youth. Thus, this paper aims to study the excellent values and educational approaches practiced by Prophet Ya’cub a.s in handling the behaviour of his children and analyse those approaches to address the youth of today’s social problem. This study used a qualitative approach in the form of content analysis. The data analysis used a descriptive approach. The samples of study include Quranic verses in Surah Yusuf related to the values of Prophet Ya’cub a.s especially in the aspect of educating children. Excellent values such as good communication, useful advice, high level of patience, taqwa to Allah and willingness to forgive others shall be applied by parents in dealing with their children’s misconduct. The implication of this study is expected to encourage the effort and create a formula in nurturing youth with good values and a noble character in their action and interaction, thereby reduce their risk of performing misconduct and getting involved in social problems.

Published: February 2020

It is widely agreed that Malaysia will achieve sustainable prosperity when its citizen live together in harmony. Moreover, a good society derives from good families and good families derive from righteous individuals who transmit insight that builds good character. In Islam, the transmission of this insight is called aqidah (belief system), which continually plays an active role in the enhancement of personal accountability. This study took a qualitative approach using personal interviews to determine methods used to teach aqidah in Malaysia. Findings revealed four methods including multimedia, slide presentations, group discussions and teacher didactics.
Counting Higgs bundles and type quiver bundles
Authors: Mozgovoy Sergey , Schiffmann Olivier
Published: February 2020

We prove a closed formula counting semistable twisted (or meromorphic) Higgs bundles of fixed rank and degree over a smooth projective curve of genus$g$defined over a finite field, when the twisting line bundle degree is at least$2g-2$(this includes the case of usual Higgs bundles). This yields a closed expression for the Donaldson–Thomas invariants of the moduli spaces of twisted Higgs bundles. We similarly deal with twisted quiver sheaves of type $A$(finite or affine), obtaining in particular a Harder–Narasimhan-type formula counting semistable$U(p,q)$-Higgs bundles over a smooth projective curve defined over a finite field.

New Findings

What is the central question of this study?

How do locomotor muscle metabo‐ and mechanoreceptor expression compare in heart failure patients and controls? Do relationships exist between the protein expression and cardiopulmonary responses during exercise with locomotor muscle neural afferent feedback inhibition?

What is the main finding and its importance?

Heart failure patients exhibited greater protein expression of transient receptor potential vanilloid type 1 and cyclooxygenase‐2 than controls. These findings are important as they identify receptors that may underlie the augmented locomotor muscle neural afferent feedback in heart failure.

Heart failure patients with reduced ejection fraction (HFrEF) exhibit abnormal locomotor group III/IV afferent feedback during exercise; however, the underlying mechanisms are unclear. Therefore, the purpose of this study was to determine (1) metabo‐ and mechanoreceptor expression in HFrEF and controls and (2) relationships between receptor expression and changes in cardiopulmonary responses with afferent inhibition. Ten controls and six HFrEF performed 5 min of cycling exercise at 65% peak workload with lumbar intrathecal fentanyl (FENT) or placebo (PLA). Arterial blood pressure and catecholamines were measured via radial artery catheter. A vastus lateralis muscle biopsy was performed to quantify cyclooxygenase‐2 (COX‐2), purinergic 2X3 (P2X3), transient receptor potential vanilloid type 1 (TRPV1), acid‐sensing ion channel 3 (ASIC3), Piezo 1 and Piezo 2 protein expression. TRPV1 and COX‐2 protein expression was greater in HFrEF than controls (both P < 0.04), while P2X3, ASIC3, and Piezo 1 and 2 were not different between groups (all P > 0.16). In all participants, COX‐2 protein expression was related to the percentage change in ventilation (r = −0.66) and mean arterial pressure (MAP) (r = −0.82) (both P < 0.01) with FENT (relative to PLA) during exercise. In controls, TRPV1 protein expression was related to the percentage change in systolic blood pressure (r = −0.77, P = 0.02) and MAP (r = −0.72, P = 0.03) with FENT (relative to PLA) during exercise. TRPV1 and COX‐2 protein levels are elevated in HFrEF compared to controls. These findings suggest that the elevated TRPV1 and COX‐2 expression may contribute to the exaggerated locomotor muscle afferent feedback during cycling exercise in HFrEF.
Perfectly matched layer absorbing boundary conditions for Euler equations with oblique mean flows modeled with smoothed particle hydrodynamics
Authors: Yang Jie , Zhang Xinyu , Liu G. R. , Mao Zirui , Zhang Wenping
Published: February 2020

Absorbing boundary conditions (ABCs) play a critical role in the simulation of sound or wave propagation problems. This paper proposes a technique of space–time transformed perfectly matched layer (PML) boundary condition implemented in a widely used mesh-free method called smoothed particle hydrodynamic (SPH) method, to absorb the outgoing sound waves with oblique shear mean flow. Special consideration is given to the particle features of the SPH, and the PMLs are formulated to correct the truncation error of SPH and absorb the outgoing wave at the same time, aiming to reduce the storage and computational cost in the infinite computational domain. Because the group velocity and phase velocity of the outgoing sound waves in the PMLs may be in different directions, exponentially growing pseudo reflections can result. The authors thus employ space–time transformation to eliminate the reflections effectively in PML boundaries for stable solutions. Moreover, a uniform framework of PML absorbing boundary conditions for Euler equations in the cases of arbitrary oblique mean flow and static media is derived. Finally, the present PML-SPH method with this stable absorbing boundary is applied to simulate sound waves propagating with mean flow. The obtained numerical results agree very well with the reference results.

Learning to deal with dual use

Published: February 2020

Biological research is profoundly valuable but can carry profound risks. The coronavirus outbreak reminds us of our vulnerability to biological threats and that research on pathogens is vital to threat mitigation. But such research can lead to catastrophic safety and security incidents. A global proliferation of tools and capabilities, driven by economic and national security interests, is also generating risks that fall outside current governance frameworks. We must learn to manage risks as quickly as we learn to manipulate life, but it remains unclear how well we are doing. One opportunity to learn is found in a new charge to the U.S. National Science Advisory Board for Biosecurity (NSABB), which reconvened in January after a 2-year hiatus, to assess the effectiveness of U.S. dual-use research oversight policies. To meet the charge and suggest improvements, the NSABB must address a neglected need for an evidence base for adaptive risk management. Building this evidence base will require revisiting success criteria, creating data infrastructures, and fostering adaptive policies and testbeds.
What matters when managing childhood fever in the emergency department? A discrete-choice experiment comparing the preferences of parents and healthcare professionals in the UK
Authors: Leigh Simon , Robinson Jude , Yeung Shunmay , Coenen Frans , Carrol Enitan D , Niessen Louis W
Published: February 2020

Background

Fever among children is a leading cause of emergency department (ED) attendance and a diagnostic conundrum; yet robust quantitative evidence regarding the preferences of parents and healthcare providers (HCPs) for managing fever is scarce.

Objective

To determine parental and HCP preferences for the management of paediatric febrile illness in the ED.

Setting

Ten children’s centres and a children’s ED in England from June 2018 to January 2019.

Participants

98 parents of children aged 0–11 years, and 99 HCPs took part.

Methods

Nine focus-groups and coin-ranking exercises were conducted with parents, and a discrete-choice experiment (DCE) was conducted with both parents and HCPs, which asked respondents to choose their preferred option of several hypothetical management scenarios for paediatric febrile illness, with differing levels of visit time, out-of-pocket costs, antibiotic prescribing, HCP grade and pain/discomfort from investigations.

Results

The mean focus-group size was 4.4 participants (range 3–7), with a mean duration of 27.4 min (range 18–46 min). Response rates to the DCE among parents and HCPs were 94.2% and 98.2%, respectively. Avoiding pain from diagnostics, receiving a faster diagnosis and minimising wait times were major concerns for both parents and HCPs, with parents willing-to-pay £16.89 for every 1 hour reduction in waiting times. Both groups preferred treatment by consultants and nurse practitioners to treatment by doctors in postgraduate training. Parents were willing to trade-off considerable increases in waiting times (24.1 min) to be seen by consultants and to avoid additional pain from diagnostics (45.6 min). Reducing antibiotic prescribing was important to HCPs but not parents.

Conclusions

Both parents and HCPs care strongly about reducing visit time, avoiding pain from invasive investigations and receiving diagnostic insights faster when managing paediatric febrile illness. As such, overdue advances in diagnostic capabilities should improve child and carer experience and HCP satisfaction considerably in managing paediatric febrile illness.

Published: February 2020

Background

A consensus on an optical coherence tomography definition of lamellar macular hole (LMH) and similar conditions is needed.

Methods

The panel reviewed relevant peer-reviewed literature to reach an accord on LMH definition and to differentiate LMH from other similar conditions.

Results

The panel reached a consensus on the definition of three clinical entities: LMH, epiretinal membrane (ERM) foveoschisis and macular pseudohole (MPH). LMH definition is based on three mandatory criteria and three optional anatomical features. The three mandatory criteria are the presence of irregular foveal contour, the presence of a foveal cavity with undermined edges and the apparent loss of foveal tissue. Optional anatomical features include the presence of epiretinal proliferation, the presence of a central foveal bump and the disruption of the ellipsoid zone. ERM foveoschisis definition is based on two mandatory criteria: the presence of ERM and the presence of schisis at the level of Henle’s fibre layer. Three optional anatomical features can also be present: the presence of microcystoid spaces in the inner nuclear layer (INL), an increase of retinal thickness and the presence of retinal wrinkling. MPH definition is based on three mandatory criteria and two optional anatomical features. Mandatory criteria include the presence of a foveal sparing ERM, the presence of a steepened foveal profile and an increased central retinal thickness. Optional anatomical features are the presence of microcystoid spaces in the INL and a normal retinal thickness.

Conclusions

The use of the proposed definitions may provide uniform language for clinicians and future research.

Published: February 2020

Background/aims

Quantitative analysis of optical coherence tomography angiography (OCT-A) images requires a reproducible approach that accounts for sectoral loss. The objective of this study was to determine whether an index that accounts for both global (perfusion density, PD) and asymmetric loss of perfusion, rather than PD alone, more reliably measures loss of perfusion in patients with glaucoma.

Methods

We analysed macular OCT-A scans of 95 glaucoma patients and 59 control subjects. Two-dimensional projection images corresponding to the superficial vascular plexus were exported and analyses performed to calculate global PD and image asymmetry. An unsigned perfusion asymmetry index (PAI) that included PD and asymmetry (with 1:1 wt) was calculated. Perfusion density and PAI were compared with 10-2 visual field mean deviation and ganglion cell layer (GCL) thickness.

Results

Median (IQR) visual field mean deviation was −1.73 (−3.76, 0.30) dB for the glaucoma group and 0.67 (0.16, 1.18) dB for the control group. The strength of the correlation with mean deviation was stronger for PAI (r=0.47), compared with PD (r=0.35), whereas with GCL thickness they were comparable (r=0.45 and 0.43, respectively). Compared with controls, mean PD was 12% lower in patients with glaucoma (0.27 vs 0.30), while PAI was 17% lower (0.40 vs 0.48). However, diagnostic accuracy of either PD or PAI was worse than GCL thickness.

Conclusions

While PAI yielded better correlation with mean deviation and GCL thickness, and a slightly improved separation between patients with glaucoma and healthy controls, diagnostic accuracy was inferior compared with GCL thickness.
Identification of a new β-thalassaemia variant Term CD+32(HBB: c.32A>C) in two Chinese families
Authors: Zhuang Jianlong , Zheng Yu , Wang Yuanbai , Zhuang Qianmei , Jiang Yuying , Xie Qingyue , Zeng Shuhong , Zeng Jianxing
Published: February 2020

Aims

β-Thalassaemia is an inherited blood disorder caused by mutations in the β-globin gene cluster. Molecular characterisation of β-thalassaemia is essential for its diagnosis and management. More and more rare and novel mutations have been reported.

Methods

Two Chinese families with β-thalassaemia from Fujian Province were recruited in this study. The phenotypes of the probands were confirmed through haematological analysis. Routine molecular analysis of thalassaemia was employed to identify the common mutations of thalassaemia. The rare and novel mutations were detected by direct DNA sequencing.

Results

In family 1, the proband, a Chinese woman aged 31 years, showed elevated level of haemoglobin A2 (HbA2). No common mutations associated with β-thalassaemia were detected, whereas a rare mutation Term CD+32(HBB: c.32A>C) was identified through DNA sequencing. Subsequent investigation of the β-thalassaemia mutation in her family showed that her mother, her brother as well as her nephew also carried this mutation. In addition, both the proband’s husband and her son carrying the rare --THAImutation exhibited decreased levels of MCH, MCH and HbA2. In family 2, the proband, a child aged 1 year, showed elevated level of HbA2, but had no common mutations of β-thalassaemia. The proband was identified carrying the mutation Term CD+32(HBB: c.32A>C), which was inherited from his mother.

Conclusions

In this study, we first report a rare β-thalassaemia mutation in Fujian Province, Southeast China. Moreover, our study also identified this rare mutation in humans. This finding has helped broaden the spectrum of β-thalassaemia mutations in our region and suggested that this rare mutation may be more prevalent in the Chinese population.
Changes in work factors and concurrent changes in leisure time physical activity: a 12-year longitudinal analysis
Authors: Biswas Aviroop , Dobson Kathleen G , Gignac Monique A M , de Oliveira Claire , Smith Peter M
Published: February 2020

Objectives

There is a paucity of longitudinal population-based studies examining whether changes in work factors are associated with concurrent changes in leisure time physical activity (LTPA). This study examines this issue using 12 years of longitudinal survey data.

Methods

Data were drawn from the Canadian National Population Health Survey. The initial analytical sample in 1994 of 6407 working individuals was followed every 2 years from 2000 to 2010. Seven work factors were measured as independent variables: skill discretion, decision authority, psychological demands, physical exertion, number of jobs, hours at work and shift schedule. LTPA was categorised as inactive, moderately active or active based on metabolic equivalent task values. Fixed-effects multinomial logistic models were used to examine associations between work factors and LTPA controlling for time-invariant effects and adjusted for covariates.

Results

Workers with lower skill discretion (OR=0.96; 95% CI 0.92 to 0.99), higher psychological demands (OR=0.95; 95% CI 0.92 to 0.99), higher physical exertion (OR=0.93; 95% CI 0.88 to 0.99) and longer work hours (OR=0.97; 95% CI 0.95 to 098) were associated with a lower odds of transitioning from inactive to active and moderately active. There was no evidence of effect modification by age or sex.

Conclusion

Results suggest that as participants’ skill discretion decreased, and their physical and psychological demands, and work hours increased, their likelihood of becoming more active and moderately active also decreased, supporting the value of targeting improvements in these work factors for physical activity interventions.
E-cigarette and cigarette purchasing among young adults before and after implementation of California’s tobacco 21 policy
Authors: Schiff Sara , Liu Fei , Cruz Tess Boley , Unger Jennifer B , Cwalina Sam , Leventhal Adam , McConnell Rob , Barrington-Trimis Jessica
Published: February 2020

Background

Tobacco 21 (T21) laws, which raise the minimum legal age of sale of tobacco products to 21, have been proposed and implemented in states and cities across the USA. However, limited data are available on the effect of T21 laws on youth tobacco purchasing behaviours and access to tobacco products.

Methods

Participants in a population-based prospective cohort in southern California completed questionnaires before (n=1609, age=18–19 y) and after (n=1502, age=19–20 y) T21 was implemented in California (June 2016). We examined the prevalence of past 30-day cigarette and e-cigarette use, and among past 30-day users, purchase location of tobacco products before (pre-) versus after (post-) T21. We also examined whether, post-T21, participants were refused purchase of tobacco products due to their age, and the perceived relative ease of purchasing cigarettes and e-cigarettes (vs pre-T21).

Results

Negligible changes in cigarette and e-cigarette use were observed pre-T21 versus post-T21. At both time points, the majority of past 30-day users purchased cigarettes from gas stations and e-cigarettes from vape shops. Post-T21, the proportion of participants who reported purchasing cigarettes at gas stations decreased. Post-T21, most past 30-day cigarette or e-cigarette users were not refused purchase of cigarettes (65.4%) or e-cigarettes (82.0%) in the past 30 days, despite being under 21; half of the participants felt it was harder to purchase cigarettes (54.3%) and e-cigarettes (43.6%) post-T21.

Conclusion

Post-T21, few participants were refused purchase of any tobacco product, despite the illegality of such sales. Better enforcement of T21 is needed to improve the efficacy of T21 legislation.

Effect of the GUP on the Hawking radiation of black hole in 2 + 1 dimensions with quintessence and charged BTZ-like magnetic black hole
Authors: Babar R. , Javed W. , Övgün A.
Published: February 2020

In this paper, we investigate the Hawking radiation process by using the quantum tunneling phenomenon of massive spin-1 (W-bosons) and spin-0 particles by the black hole in 2 + 1 dimensions surrounded by quintessence as well as charged BTZ-like magnetic black hole. First of all, by using Hamilton–Jacobi ansatz and WKB approximation to the field equation of massive vector particles, we get the required tunneling rate of emitted particles and obtain the corresponding Hawking temperature [Formula: see text] for the black hole (BH) surrounded by quintessence. In order to study the quantum gravity effects, we utilize the generalized Proca and Klein–Gordan equations incorporating the generalized uncertainty principle (GUP) for these BHs and recover their modified tunneling probability as well as accompanying quantum corrected temperatures [Formula: see text].
Gravastars in f(𝕋,𝒯) gravity
Authors: Ghosh Shounak , Kanfon A. D. , Das Amit , Houndjo M. J. S. , Salako Ines G. , Ray Saibal
Published: February 2020

We propose a stellar model under the [Formula: see text] gravity following Mazur–Mottola’s conjecture[Formula: see text] known as gravastar which is generally believed as a viable alternative to black hole. The gravastar consists of three regions, viz., (I) interior region, (II) intermediate shell region, and (III) exterior region. The pressure within the interior core region is assumed to be equal to the constant negative matter-energy density which provides a constant repulsive force over the thin shell region. The shell is assumed to be made up of fluid of ultrarelativistic plasma and following the Zel’dovich’s conjecture of stiff fluid3 it is also assumed that the pressure which is directly proportional to the matter-energy density according to Zel’dovich’s conjecture, does cancel the repulsive force exerted by the interior region. The exterior region is completely vacuum and it can be described by the Schwarzschild solution. Under all these specifications, we find out a set of exact and singularity-free solutions of the gravastar presenting several physically valid features within the framework of alternative gravity, namely [Formula: see text] gravity,4 where the part of the gravitational Lagrangian in the corresponding action is taken as an arbitrary function of torsion scalar [Formula: see text] and the trace of the energy–momentum tensor [Formula: see text].

Two kinds of composite coatings, Zn[Formula: see text]Al[Formula: see text]Mg5ZnO[Formula: see text] and Zn[Formula: see text]Al[Formula: see text]Mg5ZnO[Formula: see text], were prepared on steel matrix (Q235) by cold spraying. The Zn, Al, Mg, and ZnO in raw materials were calculated by percentage of mass. The morphology of the original coating was observed by scanning electron microscopy (SEM) and characterized by energy dispersive spectroscopy (EDS). It was found that the microstructures of Zn[Formula: see text]Al[Formula: see text]Mg5ZnO[Formula: see text] and Zn[Formula: see text]Al[Formula: see text]Mg5ZnO[Formula: see text] composite coatings prepared by cold spraying were compact without oxidation products, and the plastic deformation of powder particles was significant. The friction and wear test data of the two coatings showed that the Zn[Formula: see text]Al[Formula: see text]Mg5ZnO[Formula: see text] coating had longer-lasting protective properties and wear resistance under the same conditions. Neutral salt spray test (NSS) and electrochemical accelerated corrosion test were carried out on samples at different time periods. The results of samples’ corrosion microstructure and electrochemical curves showed that Zn[Formula: see text]Al[Formula: see text]Mg5ZnO[Formula: see text] and Zn[Formula: see text]Al[Formula: see text]Mg5ZnO[Formula: see text] have good electrochemical protection performance, and Zn[Formula: see text]Al[Formula: see text]Mg5ZnO[Formula: see text] coating has better protection effect.

Peristaltic transport in an elastic tube under the influence of dilating forcing amplitudes
Authors: Pandey Sanjay Kumar , Singh Amirlal
Published: February 2020

We investigate flow through an elastic tube which is constrained to a prescribed external forcing consisting of a progressive travelling wave. Such a flow dynamics is closely related to that in the oesophageal tube. The mechanics of the tube is characterized by a relationship between transmural pressure difference and radial variation of the tube. Dimensionless radial variation, assumed to be small, is studied by perturbation techniques. Results demonstrate that the elasticity of the tube plays a significant role in the flow dynamics. An increment in the forcing amplitude of the inward radial force enhances pressure, time-averaged volume flow rate and hence axial and radial velocities. It is revealed that the elastic nature of the oesophageal tube favors swallowing.
