Responding to mental health statutory drivers: experience of a low intensity cognitive behavioural therapy programme
Authors: Mills R. , Mowlds W. , Dyer K. F. W. , Corr P. , Kavanagh M.
Published: November 2015

Objectives

Stress control (SC), a brief psycho-education course, was implemented to increase access to psychological therapies in line with Northern Irish mental health service statutory drivers. The first aim of this study was to gauge the efficacy of SC in a robust manner with clinical significance testing. The second aim was to assess whether demographics traditionally ‘hard-to-reach’ – males, younger adults and those from deprived areas – accessed SC. The third aim was to elucidate what prompted their access and the experiences of attendees at SC.

Methods

Attendees at SC were 170 adults over six iterations of the course. Pre- and post-questionnaires included the Depression Anxiety Stress Scales – 21, captured demographic details and qualitative feedback, which was subject to a mixed-methods analysis.

Results

SC attendees reported significant decreases on depression, anxiety and stress sub-scales post-intervention. Moreover, 38.71% (n=36) of attendees who completed SC exhibited clinically significant improvement afterwards on one or more sub-scale. Attendance figures for males, younger adults and those classified as socioeconomically deprived were modest. Patterns within the data suggested prospective success for targeting these cohorts.

Conclusions

SC attracted people in need of mental healthcare input and affected quantifiable change within those people’s lives, while satisfying statutory demands for service delivery in an accessible community context. Recommendations to increase engagement with those traditionally ‘hard-to-reach’ for psychological services are provided, which, if implemented, have the potential to achieve further compliance with Northern Irish mental health statutory drivers.
Liquid toroidal drop in compressional Stokes flow
Authors: Zabarankin Michael , Lavrenteva Olga M. , Nir Avinoam
Published: November 2015

The deformation of an immiscible toroidal drop embedded in axisymmetric compressional Stokes flow is analysed via the boundary integral formulation in the case of equal viscosity. Numerical simulations are performed for the drop having initially the shape of a torus with circular cross-section. The quasi-stationary dynamic simulations reveal that, when the viscous forces, proportional to the intensity of the flow, are relatively weak compared with the surface tension (the ratio of these forces is characterized by the capillary number,$Ca$), three different scenarios of drop evolution are possible: indefinite expansion of the liquid torus, contraction to the centre and a stationary toroidal shape. When the intensity of the flow is low, the stationary shapes are shown to be close to circular tori. Once the outer flow strengthens, the cross-section of the stationary torus assumes first an elliptic and then an egg-like shape. For the capillary number greater than a critical value,$Ca_{cr}$, toroidal stationary shapes were not found. Remarkably,$Ca_{cr}$is close to the critical capillary number found previously for a simply connected drop flattened in compressional flow. Thus, a new example of non-uniqueness of stationary drop shape in viscous flow is obtained. Approximate stationary solutions in the form of tori with circular and elliptic cross-sections are obtained by minimizing the normal velocity over the drop interface. They are shown to be in good agreement with the stationary shapes from quasi-dynamic simulations for the corresponding intervals of the capillary number.
The stability of oceanic fronts in a shallow water model
Authors: Chanona Melanie , Poulin F. J. , Yawney J.
Published: November 2015

We investigate mechanisms through which energy cascades from the mesoscale, $O(100~\text{km})$, to the submesoscale, $O(10~\text{km})$, for oceanic fronts in a reduced gravity shallow water model using two different profiles. The first idealization of an ocean front has an interfacial depth that is a smooth hyperbolic tangent profile and is an extension of the piecewise constant potential vorticity profile studied in Boss et al. (J. Fluid Mech., vol. 315, 1996, pp. 65–84). By considering a range of minimum depths, all of which have the same velocity profile, we are better able to isolate the effect of vanishing layer depths. We find that the most unstable mode exists in a one-layer model and does not need two layers, as previously speculated. Moreover, we find that even without a vanishing layer depth there are other modes that appear at both larger and smaller length scales that have a gravity wave structure. The second profile is the parabolic double front from Scherer & Zeitlin (J. Fluid Mech., vol. 613, 2008, pp. 309–327). We find more unstable modes than previously presented and also categorize them based on the mode number. In particular, we find there are pairs of unstable modes that have equal growth rates. We also study the nonlinear evolution of these oceanic fronts. It is determined that vanishing layer depths have significant effects on the unstable dynamics that arise. First, stronger gravity wave fields are generated. Second, cyclonic fluid that moves into the deeper waters is stretched preferentially more in comparison to the deep water scenario and destabilizes more easily. This results in smaller scale vortices, both cyclones and anticyclones, that have length scales in the submesoscale regime. Our results suggest that the nonlinear dynamics of a front can be very efficient at generating submesoscale motions.
The stability of a rising droplet: an inertialess non-modal growth mechanism
Authors: Gallino Giacomo , Zhu Lailai , Gallaire François
Published: November 2015

Prior modal stability analysis (Kojimaet al.,Phys. Fluids, vol. 27, 1984, pp. 19–32) predicted that a rising or sedimenting droplet in a viscous fluid is stable in the presence of surface tension no matter how small, in contrast to experimental and numerical results. By performing a non-modal stability analysis, we demonstrate the potential for transient growth of the interfacial energy of a rising droplet in the limit of inertialess Stokes equations. The predicted critical capillary numbers for transient growth agree well with those for unstable shape evolution of droplets found in the direct numerical simulations of Koh & Leal (Phys. Fluids, vol. 1, 1989, pp. 1309–1313). Boundary integral simulations are used to delineate the critical amplitude of the most destabilizing perturbations. The critical amplitude is negatively correlated with the linear optimal energy growth, implying that the transient growth is responsible for reducing the necessary perturbation amplitude required to escape the basin of attraction of the spherical solution.
A NEW MAGNA CARTA FOR THE EARLY MODERN COMMON LAW: AN 800TH ANNIVERSARY ESSAY
Authors: Witte John
Published: November 2015

This article examines the influence of the Magna Carta on the development of rights and liberties in the Anglo-American common law tradition, especially in the seventeenth century. Originally issued by King John of England in 1215, the Magna Carta set forth numerous prototypical rights and liberties that helped to shape subsequent legal developments in England, America, and the broader Commonwealth. The Magna Carta served as an inspiration for seventeenth-century English jurists, like Sir Edward Coke, and Puritan pamphleteers, like John Lilburne, who advocated sweeping new rights reforms on the strength of the charter. It also inspired more directly the new bills of rights and liberties of several American colonies, most notably the expansive 1641 Body of Liberties of Massachusetts crafted by Nathaniel Ward, which anticipated many of the constitutional rights formulations of eighteenth- and nineteenth-century America.
Realization of Resonance of a Diaphragm at Any Desired Frequency
Authors: Zhang Y. , Huang L.
Published: November 2015

In noise control, the reactance of a mechanical system needs to be minimized while the resistance is chosen suitably. This work illustrates the possibility of and the ease at which such design tasks may be accomplished by utilizing strong electromechanical coupling. Moving-coil loudspeaker is chosen as the vehicle of illustration and it is considered as a simple spring-mass system when operated below its first diaphragm mode. It is shown that the system mechanical property may be tuned easily by a simple R-LC circuit. In addition to the assigned resonance frequency, there can be a maximum of two other resonances. It is argued that the ability to tune the system mechanical resonance to any frequency, such as the ones at very low frequencies, can be very useful for noise and vibration control applications.
Fuzzy Solutions for Two-Dimensional Navier-Stokes Equations
Authors: Chen Y.-Y. , Hsiao R.-J. , Huang M.-C.
Published: November 2015

A new methodology via using an adaptive fuzzy algorithm to obtain solutions of “Two-dimensional Navier-Stokes equations” (2-D NSE) is presented in this investigation. The design objective is to find two fuzzy solutions to satisfy precisely the 2-D NSE frequently encountered in practical applications. In this study, a rough fuzzy solution is formulated with adjustable parameters firstly, and then, a set of adaptive laws for optimally tuning the free parameters in the consequent parts of the proposed fuzzy solutions are derived from minimizing an error cost function which is the square summation of approximation errors of boundary conditions, continuum equation and Navier-Stokes equations. In addition, elegant approximated error bounds between the exact solution and the proposed fuzzy solution with respect to the number of fuzzy rules and solution errors have also been proven. Furthermore, the error equations in mesh points can be proven to converge to zero for the 2-D NSE with two sufficient conditions.

Authors: Zhang Wei-Ting , Shih Chung-Kun , Labandeira Conrad C. , Ren Dong
Published: November 2015

A new genus and species, Aclemus patulus n. gen. n. sp., is described based on a new specimen collected from the latest Middle Jurassic Jiulongshan Formation in Inner Mongolia, China. Based on a combination of characters from this fossil, including a homonomous fore- and hindwing, a 3-branched media vein, wings lacking long cilia on their margins; and a cross-vein absent between subcosta and radius, we establish a new genus assigned to the Eolepidopterigidae. In addition, the diagnosis of Longcapitalis excelsus Zhang, Shih, Labandeira and Ren 2013, is emended based on new fossil material.
Application of a continuous time delay-difference model for the population dynamics of winter-spring cohort of neon flying squid (Ommastrephes bartramii, Lesueur 1821) in the North-west Pacific Ocean

Published: November 2015

A continuous time delay-difference model (CD-DM) was applied to the Chinese neon flying squid (Ommastrephes bartramii) jigging fisheries data (2001–2004) in the north-west Pacific Ocean. The continuous time delay-difference model (CD-DM) was modified from the discrete-time delay-difference model (D-DM), in which recruitment, growth and mortality rates are treated as varying continuously over time. Some commercially important stocks, such as shrimp andO. bartramiwith recruitment, growth and mortality rates all varying continuously over time, may be better analysed by a continuous delay-difference model. We estimated the growth and recruitment ofO. bartramiion the basis of the CD-DM, and biological reference points (BRPs) and accuracy of estimates are discussed in this study. We obtained population sizes of 183.9–201.8 million squid during early September 2004. The status of the stock was not in a sustainable state at this time with the available data, which suggests that measures should be taken for the sustainable utilization of this stock. The ability to calculate reference points without need of a full age-structured data makes CD-DM an attractive option for data-poor fisheries. We provided an alternative method for assessingO. bartramiistock and bridged the gap between simple surplus production models and complex fully age-structured models.
Polyphenols and non-alcoholic fatty liver disease: impact and mechanisms
Authors: Rodriguez-Ramiro I. , Vauzour D. , Minihane A. M.
Published: November 2015

Non-alcoholic fatty liver disease (NAFLD) is considered to be the hepatic component of the metabolic syndrome and its prevalence is rapidly increasing due to its strong association with insulin resistance and obesity. At present, given that NAFLD is highly prevalent and therapies are limited, much attention is focused on identifying effective dietary strategies for the prevention and treatment of the disease. Polyphenols are a group of plant bioactive compounds whose regular consumption have been associated with a reduction in the risk of a number of metabolic disorders associated with NAFLD. Here we review the emerging and relatively consistent evidence from cell culture and rodent studies showing that select polyphenols positively modulate a variety of contributors to the NAFLD phenotype, through diverse and complementary mechanisms of action. In particular, the reduction ofde novolipogenesis (via sterol regulatory element-binding protein 1c) and increased fatty acid β-oxidation, presumably involving AMP-activated protein kinase activation, will be discussed. The indirect antioxidant and anti-inflammatory properties of polyphenols which have been reported to contribute to the amelioration of NAFLD will also be addressed. In addition to a direct study of the liver, rodent studies have provided insight into the impact of polyphenols on adipose tissue function and whole body insulin sensitivity, which are likely to in part modulate their impact on NAFLD development. Finally an overview of the limited data from clinical trials will be given along with a discussion of the dose extrapolation from animal studies to human subjects.

Published: November 2015

Giardia duodenalisis a common intestinal parasite infecting children attending daycare centres. This study aimed to verifyGiardiaoccurrence and the genotypes of isolates infecting children aged 0–6 years and workers at a daycare centre in the state of São Paulo, Brazil. The families of children who tested positive forGiardia, were asked to provide stool samples from household members and their dogs. Samples (123 children, 14 centre employees, 44 household members, 19 children after treatment, and 20 dogs) were examined for intestinal parasites using concentration methods. DNA extracted from all samples was submitted for polymerase chain reaction (PCR) testing and the amplicons generated were used for multilocus sequence typing of beta-giardin (bg), triose phosphate isomerase (tpi) and glutamate dehydrogenase (gdh) genes.Giardiawas detected in 15·9% and 28·6% of the 220 samples by microscopy and PCR, respectively. Analysis of sequences retrieved from 29 isolates revealed both assemblages A (31%) and B (69%). Sub-assemblages AII, BIII and BIV were identified and the alignment of thebg, gdhandtpisequences revealed the presence of some single nucleotide polymorphisms, especially in assemblage B sequences. The higher predominance of assemblage B and the identification of the AII type support the view that anthroponotic transmission appears to be an important route of transmission in environments that concentrate children at an age when poor hygiene practices make them more vulnerable to such infection.
Evaluation of Bag-Valve-Mask Ventilation by Paramedics in Simulated Chemical, Biological, Radiological, or Nuclear Environments
Authors: Schumacher Jan , Weidelt Lena , Gray Stuart A. , Brinker Andrea
Published: November 2015

Introduction:

Bag-valve-mask ventilation is a key component of life support, but only one handheld resuscitator is designed to operate in contaminated or toxic atmospheres.

Methods:

After Institutional Review Board approval, the efficacy of this device was evaluated. The distal trachea of a LaerdalTM Airway Management Trainer was connected to a mechanical Draeger Volumeter 3000TM to enable determination of the minute volume delivered by BVM ventilation. Nineteen paramedics wearing chemical, biological, radiological, or nuclear (CBRN) protective equipment were asked to ventilate this modified airway trainer, either with or without a CBRN filter attached to the inlet filtration system of the AMBUTM Mark III Resuscitator. The maximum levels of minute ventila-tion achieved were compared. Values are given as mean ±SD. A paired t-test was used to detect any differences between the two groups, p-values of <0.05 were defined to show statistical significance.

Results:

The described model allowed a reproducible and reliable measurement of the delivered minute ventilation. All paramedics were able to operate the device without prior CBRN training. The maximum minute volume achieved without the filter was 9.5 ±2.7 l/min. Use of the inlet CBRN filtra-tion system reduced the maximum minute volume to 6.3 ±2.0 l/min, reduction: 23%. The achieved maximum minute volumes ranged from 15 to 4.9 l/min in the controls and from 9.8 to 1.4 l/min in the CBRN group. Four paramedics were unable to achieve a minute volume >5 l/min in the CBRN group, one participant failed to achieve that value in the control group. The inherent breathing resistance of the CBRN filter appears to reduce the inflow of air into the self-inflatable bag. This delay in refilling may have resulted in a reduced achievable minute volume.

Conclusions:

The range of maximum minute volumes observed in both groups highlights the need for continuous BVM ventilator training.
A Reassessment and Review of the Bam Earthquake Five Years Onward: What Was Done Wrong?
Authors: Motamedi Mohammad Hosein Kalantar , Saghafinia Masoud , Bafarani Azadeh Hassani , Panahi Farzad
Published: November 2015

Introduction:

An earthquake measuring 6.6 on the Richter scale on 23 December 2003 devastated the city of Bam in southeastern Iran. During the response and recovery phases, considerable shortcomings were discovered. The dire situation in the affected area, a variety of urgently required interventions, and the large number of aid organizations involved brought about difficulties in management, coordination, and communication among authorities and aid organizations. This article highlights flaws in management in the var-ious aspects of this disaster in order to assess what was done, and what should be done to overcome these shortcomings in future disasters.

Methods:

A retrospective review of the various aspects of management related to the Bam disaster was done via the assessment of files, multi-center studies, governmental data, and available literature from 2003–2008.

Results:

A review of the available data relevant to search and rescue (S&R) operations and short-term aid provision revealed flaws in different aspects of disaster management including personnel, the transfer of the injured, availability medical supplies, treatment planning, problems concerning the composition of treatment forces dispatched to the region, distribution of tasks among treatment workers, transferring of equipment, availability of facilities, and lack of coordination among the organizations responsible for the management of the disaster. Most of the aforementioned issues have been addressed.

Conclusions:

A comprehensive disaster management plan must not be limited only to the response phase, but rather must include: preparedness, recovery with optimal legislation and budgeting, improvement of healthcare facilities, and organized communication channels between the different governmental departments. This important issue has been addressed, and a disaster management organization under the supervision of the President has been established, developing a national S&R strategy and protocol for unified managerial organization, an alert system, an international disaster command system (under which S&R and emergency medical service teams can be deployed, increasing the efficacy and coordination of the arrival of foreign teams and the con-struction field hospitals), and developing a flowchart to coordinate international agencies and the domestic authorities in charge. Continuous education, training of the general population, conducting periodic exercise drills, and provision for prepared task force mobilization in disaster management all are important aspects of the management of disasters due to natural hazards.
Evacuation and Sheltering of Hospitals in Emergencies: A Review of International Experience
Authors: Bagaria Jayshree , Heggie Caroline , Abrahams Jonathan , Murray Virginia
Published: November 2015

Objective:

A scoping exercise to establish how common hospital evacuations are, identify hospital evacuation policies and review case studies to identify trig-gers, processes and challenges involved in the evacuation of hospitals globally.

Design:

A systematic search of PubMed and disaster agency online resources, search of grey literature and media reports.

Results:

This study showed that hospitals are vulnerable to both natural and man made disasters and that hospital evacuations do occur globally. It highlighted the paucity of published data and policy on hospital evacuation and emphasised the vital need to collect data on triggers, reasons for evacuation, sheltering facilities and the process of evacuation.

Conclusions:

This study recommends the collection of case studies and the development of a database to assist with the research and development of well tailored hospital evacuation plans. These recommendations reflect and support the 2008-2009 World Disaster Reduction Campaign on Hospitals Safe from Disasters and the timely 2009 Global Platform priority that, ‘Critical services and infrastructure such as health facilities and schools must be safe from disasters.
Disaster Relief and Recovery after a Landslide at a Small, Rural Hospital in Guatemala
Authors: Peltan Ithan D.
Published: November 2015

Introduction:

Though many reports have assessed hospital emergency responses during a disaster that affected the facility's operations, relatively little work has been dedicated to identifying factors that aid or impede the recovery of such hospitals.

Problem:

On 05 October 2005, Hurricane Stan triggered landslides that buried an impoverished Mayan community in Santiago Atitlán, Guatemala. The six-bed Hospitalito Atitlán also was in the landslide's path. Though opened just months earlier, the institution maintained 24-hour services until reopening in a new facility only 15 days after the landslides.

Methods:

This qualitative study examined the Hospitalito Atitlán's disaster recovery using unstructured interviews with key hospital personnel and community members. Participant observation provided information about institutional and cultural dynamics affecting the hospital's recovery. Data were collected retrospectively during June–September 2006 and June 2007.

Results:

The Hospitalito's emergency responses and recovery were distinct endeavors that nonetheless overlapped in time. The initial 12 hours of disorganized emergency relief work was quickly succeeded by an organized effort by the institution to provide inpatient and clinic-based care to the few severely injured and many worried-well patients. As international aid started arriving 2–3 days post-landslide, the Hospitalito's 24-hour clinical services made it an integral organization in the comprehensive health response. Meanwhile, a subset of the Hospitalito's non-clinical staff initiated rebuilding efforts by Day 2 after the event, joined later by medical staff as outside aid allowed them to handoff clinical duties. Effective use of the Internet and conventional media promoted donations of money and supplies, which provided the raw materials used by a group determined to reopen their hospital.

Conclusions:

Early work by a recovery-focused team coupled with a shared understanding of the Hospitalito as an institution that transcended its damaged building drove the hospital's rapid post-emergency revival. Encouraging a similar sense of mission, emulating the Hospitalito's handling of funding and material procurement, and conducting rebuilding and relief efforts in parallel may aid recovery at other health facilities.
Polypeptide formation on polar mineral surfaces: possibility of complete chirality
Authors: Schrader Malcolm E.
Published: November 2015

In the present work, it is shown that thermodynamically feasible polymerization of cyanomethanol, which can be formed from formaldehyde and hydrogen cyanide, can lead to synthesis of polypeptides as well as to the previously reported synthesis of RNA. If the polymerization takes place on a one-dimensional feature of a mineral, such as for example a crack on its surface, the concept of quasi-chirality is introduced to describe the adsorbed polypeptide. This, in principle, would lead to formation of proteins that are completely homochiral in their alpha carbon groups. The concept of quasi-chirality can also be introduced in the condensation of glycine under similar conditions to form a polypeptide. This again leads to proteins completely chiral in their alpha carbon groups.
Promoting the utilization of plant, animal and microbial genetic resources for research and development in biotechnology: evidence on researchers' preferences for specific attributes from Korean genebanks
Authors: Sung Bongsuk , Hwang Kyungyun
Published: November 2015

With regard to the survey data of Korean researchers using genetic resources from three genebanks administered by the Korea Research Institute of Bioscience and Biotechnology, we conducted conjoint and cluster analyses to estimate the relative importance of genetic resource (microbial, plant and animal) attributes among the researchers. Our results indicate that Korean researchers view price (cost of acquiring an accession), high new functionality (functional properties of germplasms for specific applications and uses) and completely uncovered genomic information (about mutation, genetic transformation, genomic function and pathways) as far more important in decision-making about R&D use of microbial, plant and animal genetic resources, respectively, than other attributes. Furthermore, this study shows that researchers conducting R&D in the microbial and plant genetic resource sectors especially prefer resources from specific domestic environments and Korean indigenous species, respectively. The study also sheds light on different patterns of researcher segments in terms of utilities of attributes and subgroups of researchers who have common needs in the three genetic resource sectors. We proposed some policy and strategic implications based on the results of this study.
The Influence of Leadership Style on Subordinates’ Attachment to the Leader
Authors: Molero Fernando , Moriano Juan A. , Shaver Phillip R.
Published: November 2015

The aim of this research is to explore the extent to which employees establish attachment bonds with their leaders and the effects these bonds have on organizational outcomes. A sample of 225 participants reported on their supervisor’s leadership style (transformational, transactional, or passive-avoidant), their attachment bonds to this supervisor (anxious or avoidant), and four organizational variables (subordinate’s satisfaction, identification with the organization, extra effort, and perceived leadership effectiveness). Results, analyzed using a Partial Least Squares (PLS) approach, indicated that (a) transformational leadership was negatively associated with employees’ insecure (anxious or avoidant) attachment to their leader; (b) passive/avoidant leadership was positively associated with subordinates’ insecure attachment to their leader; (c) transactional leadership was positively associated with employee’s anxious attachment but not with their avoidant attachment; (d) avoidant, but not anxious, attachment to the leader was negatively associated with employee satisfaction, perceived leader effectiveness, employee’s extra effort, and organizational identification.
The Color Red Supports Avoidance Reactions to Unhealthy	Food
Authors: Rohr Michaela , Kamm Friederike , Koenigstorfer Joerg , Groeppel-Klein Andrea , Wentura Dirk
Published: November 2015

Abstract. Empirical evidence suggests that the color red acts like an implicit avoidance cue in food contexts. Thus specific colors seem to guide the implicit evaluation of food items. We built upon this research by investigating the implicit meaning of color (red vs. green) in an approach-avoidance task with healthy and unhealthy food items. Thus, we examined the joint evaluative effects of color and food: Participants had to categorize food items by approach-avoidance reactions, according to their healthfulness. Items were surrounded by task-irrelevant red or green circles. We found that the implicit meaning of the traffic light colors influenced participants’ reactions to the food items. The color red (compared to green) facilitated automatic avoidance reactions to unhealthy foods. By contrast, approach behavior toward healthy food items was not moderated by color. Our findings suggest that traffic light colors can act as implicit cues that guide automatic behavioral reactions to food.
Memorability in Context
Authors: Geurten Marie , Meulemans Thierry , Willems Sylvie
Published: November 2015

Abstract. We examined children’s ability to employ a metacognitive heuristic based on memorability expectations to reduce false recognitions, and explored whether these expectations depend on the context in which the items are presented. Specifically, 4-, 6-, and 9-year-old children were presented with high-, medium-, and low-memorability words, either mixed together (Experiment 1) or separated into two different lists (Experiment 2). Results revealed that only children with a higher level of executive functioning (9-year-olds) used the memorability-based heuristic when all types of items were presented within the same list. However, all children, regardless of age or executive level, implemented the metacognitive rule when high- and low-memorability words were presented in two separate lists. Moreover, the results of Experiment 2 showed that participants processed medium-memorability words more conservatively when they were presented in a low- than in a high-memorability list, suggesting that children’s memorability expectations are sensitive to list-context effects.
Retrospective Evaluations of Sequences
Authors: Aldrovandi Silvio , Poirier Marie , Kusev Petko , Ayton Peter
Published: November 2015

Abstract. Retrospective evaluation (RE) of event sequences is known to be biased in various ways. The present paper presents a series of studies that examined the suggestion that the moments that are the most accessible in memory at the point of RE contribute to these biases. As predicted by this memory-based analysis, Experiment 1 showed that pleasantness ratings of word lists were biased by the presentation position of a negative item and by how easy the negative information was to retrieve. Experiment 2 ruled out the hypothesis that these findings were due to the dual nature of the task called upon. Experiment 3 further manipulated the memorability of the negative items – and corresponding changes in RE were as predicted. Finally, Experiment 4 extended the findings to more complex stimuli involving event narratives. Overall, the results suggest that assessments were adjusted based on the retrieval of the most readily available information.
The Utility of Testing Noncognitive Aptitudes as Additional	Predictors of Graduation From US Air Force Air Traffic Controller	Training
Authors: Chappelle Wayne , Thompson William , Goodman Tanya , Bryan Craig J. , Reardon Laura
Published: November 2015

Abstract. The present study examined the utility of testing noncognitive aptitudes as a predictor of graduation from US Air Force air traffic controller (ATC) training. A total of 1,003 training candidates participated in the study. Results of logistic regression indicate that noncognitive areas of functioning at the start of training significantly predicted graduation beyond the effects of a measure of cognitive aptitude. Higher levels of emotional self-awareness, self-actualization, reality testing, stress tolerance, happiness, and approach to problem solving best differentiated graduates from nongraduates. The results of the study suggest such areas of functioning are important for training success.
Correlation of Changes in the Employment Costs and Average Task Load	With Rates of Accidents Attributed to Human Error
Authors: Karanikas Nektarios
Published: November 2015

Abstract. Market competition and global financial uncertainty have been the principal drivers that impel aviation companies to proceed to budget cuts, including decreases in salary and work force levels, in order to ensure viability and sustainability. Under the concepts of Maslow and Herzberg’s motivation theories, the current paper unfolds the influence of employment cost fluctuations on an aviation organization’s accidents attributed to human error. This study exploited financial and accident data over a period of 13 years, and explored whether rates of accidents attributed to human errors of flight, maintenance, and ramp crews, correlate with the average employment expenditures (N = 13). In addition, the study took into account the relationship between average task load (ratio of flying hours per employee) and accident rates related to human error since task load, as part of total workload, is a constraint of modern complex systems. The results revealed strong correlations among accident rates linked to human error with the average employment costs and task load. The use of more specific data per aviation organizational department and professional group may further validate the results of this study. Organizations that seek to explore the association between human error and employment budget and task load might appropriately adapt the approach proposed.
Integrative genomic mining for enzyme function to enable engineering of a non-natural biosynthetic pathway
Authors: Mak Wai Shun , Tran Stephen , Marcheschi Ryan , Bertolani Steve , Thompson James , Baker David , Liao James C. , Siegel Justin B.
Published: November 2015

The ability to biosynthetically produce chemicals beyond what is commonly found in Nature requires the discovery of novel enzyme function. Here we utilize two approaches to discover enzymes that enable specific production of longer-chain (C5–C8) alcohols from sugar. The first approach combines bioinformatics and molecular modelling to mine sequence databases, resulting in a diverse panel of enzymes capable of catalysing the targeted reaction. The median catalytic efficiency of the computationally selected enzymes is 75-fold greater than a panel of naively selected homologues. This integrative genomic mining approach establishes a unique avenue for enzyme function discovery in the rapidly expanding sequence databases. The second approach uses computational enzyme design to reprogramme specificity. Both approaches result in enzymes with >100-fold increase in specificity for the targeted reaction. When enzymes from either approach are integrated in vivo, longer-chain alcohol production increases over 10-fold and represents >95% of the total alcohol products.
Three-dimensional magnetic cloak working from d.c. to 250 kHz
Authors: Zhu Jianfei , Jiang Wei , Liu Yichao , Yin Ge , Yuan Jun , He Sailing , Ma Yungui
Published: November 2015

Invisible cloaking is one of the major outcomes of the metamaterial research, but the practical potential, in particular for high frequencies (for example, microwave to visible light), is fatally challenged by the complex material properties they usually demand. On the other hand, it will be advantageous and also technologically instrumental to design cloaking devices for applications at low frequencies where electromagnetic components are favourably uncoupled. In this work, we vastly develop the bilayer approach to create a three-dimensional magnetic cloak able to work in both static and dynamic fields. Under the quasi-static approximation, we demonstrate a perfect magnetic cloaking device with a large frequency band from 0 to 250 kHz. The practical potential of our device is experimentally verified by using a commercial metal detector, which may lead us to having a real cloaking application where the dynamic magnetic field can be manipulated in desired ways.
Searching for new ferroelectrics and multiferroics: A user’s point of view
Authors: Scott J F
Published: November 2015

A perspective on computational studies of ferroelectrics and multiferroics is given that emphasises what has yet to be done, along with some subtleties in previously studied systems. Beginning with the extensive data-mining studies of Abrahams and more recently, Rabe, a survey is given of magnetostrictive effects in antiferromagnetic antiferroelectrics (after Toledano and Toledano), which has an nonmagnetic analogy in the antiferroelectric phase of tris-sarcosine calcium chloride and a reminder of the unusual spin–phonon coupling of Holden et al. in systems such as KCoF3 and EuTiO3. Attention is also paid to field-temperature phase diagrams, finite non-periodic boundary conditions, and processing-dependent structures.
Replicating the benefits of Deutschian closed timelike curves without breaking causality

Published: November 2015

In general relativity, closed timelike curves can break causality with remarkable and unsettling consequences. At the classical level, they induce causal paradoxes disturbing enough to motivate conjectures that explicitly prevent their existence. At the quantum level such problems can be resolved through the Deutschian formalism, however this induces radical benefits—from cloning unknown quantum states to solving problems intractable to quantum computers. Instinctively, one expects these benefits to vanish if causality is respected. Here we show that in harnessing entanglement, we can efficiently solve NP-complete problems and clone arbitrary quantum states—even when all time-travelling systems are completely isolated from the past. Thus, the many defining benefits of Deutschian closed timelike curves can still be harnessed, even when causality is preserved. Our results unveil a subtle interplay between entanglement and general relativity, and significantly improve the potential of probing the radical effects that may exist at the interface between relativity and quantum theory.

Coral reefs are in decline worldwide due to a combination of local and global causes. Over 40% of the recent coral loss on Australia’s Great Barrier Reef (GBR) has been attributed to outbreaks of the coral-eating Crown-of-Thorns Seastar (CoTS). Testing of the hypotheses explaining these outbreaks is hampered by an inability to investigate the spatio-temporal distribution of larvae because they resemble other planktotrophic echinoderm larvae. We developed a genetic marker and tested it on 48 plankton samples collected during the 2014 spawning season in the northern GBR and verified the method by PCR amplification of single larva. Surprisingly, most samples collected contained CoTS larvae. Larvae were detected 100 km south of current outbreaks of adult seastars, highlighting the potential for rapid expansion of the outbreak. A minimum estimate suggested that larvae numbers in the outbreak area (>1010) are about 4 orders of magnitude higher than adults (~106) in the same area, implying that attempts to halt outbreaks by removing adults may be futile.

Tropical tuna fisheries are central to food security and economic development of many regions of the world. Contemporary population assessment and management generally assume these fisheries exploit a single mixed spawning population, within ocean basins. To date population genetics has lacked the required power to conclusively test this assumption. Here we demonstrate heterogeneous population structure among yellowfin tuna sampled at three locations across the Pacific Ocean (western, central and eastern) via analysis of double digest restriction-site associated DNA using Next Generation Sequencing technology. The differences among locations are such that individuals sampled from one of the three regions examined can be assigned with close to 100% accuracy demonstrating the power of this approach for providing practical markers for fishery independent verification of catch provenance in a way not achieved by previous techniques. Given these results, an extended pan-tropical survey of yellowfin tuna using this approach will not only help combat the largest threat to sustainable fisheries (i.e. illegal, unreported and unregulated fishing) but will also provide a basis to transform current monitoring, assessment and management approaches for this globally significant species.

Failure to close the neural tube results in birth defects, with severity ranging from spina bifida to lethal anencephaly. Few genetic risk factors for neural tube defects are known in humans, highlighting the critical role of environmental risk factors, such as maternal diabetes. Yet, it is not well understood how altered maternal metabolism interferes with embryonic development and with neurulation in particular. We present evidence from two independent mouse models of diabetic pregnancy that identifies impaired migration of nascent mesodermal cells in the primitive streak as the morphogenetic basis underlying the pathogenesis of neural tube defects. We conclude that perturbed gastrulation not only explains the neurulation defects, but also provides a unifying etiology for the broad spectrum of congenital malformations in diabetic pregnancies.

The thyroid imaging reporting and data system (TIRADS) and Bethesda system for reporting thyroid cytopathology (BSRTC) have been used for interpretation of ultrasound and fine-needle aspiration cytology (FNAC) results of thyroid nodules. BRAFV600Emutation analysis is a molecular tool in diagnosing thyroid carcinoma. Our objective was to compare the diagnostic value of these methods in differentiating high-risk thyroid nodules. Total 220 patients with high-risk thyroid nodules were recruited in this prospective study. They all underwent ultrasound, FNAC and BRAFV600Emutation analysis. The sensitivity and specificity of TIRADS were 73.1% and 88.4%. BSRTC had higher specificity (97.7%) and similar sensitivity (77.6%) compared with TIRADS. The sensitivity and specificity of BRAFV600Emutation (85.1%, 100%) were the highest. The combination of BSRTC and BRAFV600Emutation analysis significantly increased the efficiency, with 97.8% sensitivity, 97.7% specificity. In patients with BSRTC I-III, the mutation rate of BRAFV600Ewas 64.5% in nodules with TIRADS 4B compared with 8.4% in nodules with TIRADS 3 or 4A (P < 0.001). Our study indicated that combination of BSRTC and BRAFV600Emutation analysis bears a great value in differentiating high-risk thyroid nodules. The TIRADS is useful in selecting high-risk patients for FNAB and patients with BSRTC I-III for BRAFV600Emutation analysis.

Spin torque oscillators (STOs) are compact, tunable sources of microwave radiation that serve as a test bed for studies of nonlinear magnetization dynamics at the nanometer length scale. The spin torque in an STO can be created by spin-orbit interaction, but low spectral purity of the microwave signals generated by spin orbit torque oscillators hinders practical applications of these magnetic nanodevices. Here we demonstrate a method for decreasing the phase noise of spin orbit torque oscillators based on Pt/Ni80Fe20 nanowires. We experimentally demonstrate that tapering of the nanowire, which serves as the STO active region, significantly decreases the spectral linewidth of the generated signal. We explain the observed linewidth narrowing in the framework of the Ginzburg-Landau auto-oscillator model. The model reveals that spatial non-uniformity of the spin current density in the tapered nanowire geometry hinders the excitation of higher order spin-wave modes, thus stabilizing the single-mode generation regime. This non-uniformity also generates a restoring force acting on the excited self-oscillatory mode, which reduces thermal fluctuations of the mode spatial position along the wire. Both these effects improve the STO spectral purity.

The removal of eggs or chicks from wild populations to create captive populations, reinforce free-ranging populations or reintroduce species into the wild is a restoration tool that requires an assessment of potential detrimental effects upon the donor population. This is an absolute prerequisite when wild donor populations are scarce and small. Here, we forecast the population trend of the largest European population of the bearded vulture (Gypaetus barbatus) over the next 30 years under different demographic and management scenarios (removal of eggs, chicks or fledglings). Projections derived from the combination of a PDP model (Population Dynamic P-system) and a Box-Behnken design would lead to a decline in 77% of all 57 scenarios analysed. Among the 13 scenarios predicting a population increase, only 4 seem realistic in terms of growth rate (0.04%–1.01%), at least if current age at first breeding and productivity would remain constant over time. Our simulations thus suggest that most extraction scenarios would have detrimental effects on the demography of the donor population. Release of captive-born young or removal of only the second hatched chick for subsequent captive rearing and translocation into the wild appear to represent much better supplementation and reintroduction options in this threatened species.
