Published: February 2015

ABSTRACTBeavers (Castor canadensis) influence habitat for many species and pose challenges in developed landscapes. They are increasingly viewed as a cost‐efficient means of riparian habitat restoration and water storage. Still, information on their status is rare, particularly in western North America. We used aerial photography to evaluate changes in beaver occupancy between 1942–1968 and 2009 in upper portions of 2 large watersheds in Oregon, USA. We used multiple observers and occupancy modeling to account for bias related to photo quality, observers, and imperfect detection of beaver impoundments. Our analysis suggested a slightly higher rate of beaver occupancy in the upper Deschutes than the upper Klamath basin. We found weak evidence for beaver increases in the west and declines in eastern parts of the study area. Our study presents a method for dealing with observer variation in photo interpretation and provides the first assessment of the extent of beaver influence in 2 basins with major water‐use challenges.

AbstractThe aim of this guidance paper of the European Psychiatric Association is to provide evidence-based recommendations on the early detection of a clinical high risk (CHR) for psychosis in patients with mental problems. To this aim, we conducted a meta-analysis of studies reporting on conversion rates to psychosis in non-overlapping samples meeting any at least any one of the main CHR criteria: ultra-high risk (UHR) and/or basic symptoms criteria. Further, effects of potential moderators (different UHR criteria definitions, single UHR criteria and age) on conversion rates were examined. Conversion rates in the identified 42 samples with altogether more than 4000 CHR patients who had mainly been identified by UHR criteria and/or the basic symptom criterion ‘cognitive disturbances’ (COGDIS) showed considerable heterogeneity. While UHR criteria and COGDIS were related to similar conversion rates until 2-year follow-up, conversion rates of COGDIS were significantly higher thereafter. Differences in onset and frequency requirements of symptomatic UHR criteria or in their different consideration of functional decline, substance use and co-morbidity did not seem to impact on conversion rates. The ‘genetic risk and functional decline’ UHR criterion was rarely met and only showed an insignificant pooled sample effect. However, age significantly affected UHR conversion rates with lower rates in children and adolescents. Although more research into potential sources of heterogeneity in conversion rates is needed to facilitate improvement of CHR criteria, six evidence-based recommendations for an early detection of psychosis were developed as a basis for the EPA guidance on early intervention in CHR states.

AbstractPsychiatry is that branch of the medical profession, which deals with the origin, diagnosis, prevention, and management of mental disorders or mental illness, emotional and behavioural disturbances. Thus, a psychiatrist is a trained doctor who has received further training in the field of diagnosing and managing mental illnesses, mental disorders and emotional and behavioural disturbances. This EPA Guidance document was developed following consultation and literature searches as well as grey literature and was approved by the EPA Guidance Committee. The role and responsibilities of the psychiatrist include planning and delivering high quality services within the resources available and to advocate for the patients and the services. The European Psychiatric Association seeks to rise to the challenge of articulating these roles and responsibilities. This EPA Guidance is directed towards psychiatrists and the medical profession as a whole, towards other members of the multidisciplinary teams as well as to employers and other stakeholders such as policy makers and patients and their families.
Cancer of the cervix: Early detection and cost‐effective solutions
Authors: Denny Lynette , Prendiville Walter 
Published: February 2015

AbstractCervical cancer is known to be a preventable disease through the detection of cervical cancer precursors, historically using cytology of the cervix as the primary screening test. Over 85% of cervical cancer cases and deaths occur in low‐resource countries. Alternatives to cytology have been investigated with the strongest possibilities being visual inspection with acetic acid (VIA) and HPV DNA testing. HPV DNA testing has been shown in randomized trials to be significantly more sensitive for the detection of cervical cancer precursors than either cytology or VIA. In this paper we argue that prevention really does cost less than cure, or that prevention and treatment of cancer costs less than no prevention, in effect just treatment, of cancer. The true cost savings of prevention will include a more difficult assessment of the socioeconomic savings associated with longer, healthier lives for women in their prime who have a major role in supporting their families.
Food, Obesity Discourses and the Subjugation of Environmental Knowledge
Authors: O’Flynn Gabrielle 
Published: February 2015

AbstractIn this article, I critically analyse how meanings of health and food, tied to obesity reduction, ‘subjugate’ environmental priorities and knowledges of food. To do this, I explore the meanings of health and food constructed in the NSW Health Munch & Move program. I examine the use of language to construct notions of food and health that are not only difficult to challenge, but difficult to think otherwise, including in relation to environmental perspectives of food. I argue that as calculative and individualised conceptualisations of food and health become more and more ‘common sense’ (Mudry, 2009), there is a ‘closing off’ of what is thinkable and doable in relation to food and health. The subjugation of environmental priorities of food takes place both through their marginalisation and through how we are invited to define the place of food in our lives.
Optimal control of energy extraction in wind-farm boundary layers
Authors: Goit Jay P. , Meyers Johan 
Published: February 2015

In very large wind farms, the vertical interaction with the atmospheric boundary layer plays an important role, i.e. the total energy extraction is governed by the vertical transport of kinetic energy from higher regions in the boundary layer towards the turbine level. In the current study, we investigate optimal control of wind-farm boundary layers, considering the individual wind turbines as flow actuators, whose energy extraction can be dynamically regulated in time so as to optimally influence the flow field and the vertical energy transport. To this end, we use large-eddy simulations of a fully developed pressure-driven wind-farm boundary layer in a receding-horizon optimal control framework. For the optimization of the wind-turbine controls, a conjugate-gradient optimization method is used in combination with adjoint large-eddy simulations for the determination of the gradients of the cost functional. In a first control study, wind-farm energy extraction is optimized in an aligned wind farm. Results are accumulated over one hour of operation. We find that the energy extraction is increased by 16 % compared to the uncontrolled reference. This is directly related to an increase of the vertical fluxes of energy towards the wind turbines, and vertical shear stresses increase considerably. A further analysis, decomposing the total stresses into dispersive and Reynolds stresses, shows that the dispersive stresses increase drastically, and that the Reynolds stresses decrease on average, but increase in the wake region, leading to better wake recovery. We further observe also that turbulent dissipation levels in the boundary layer increase, and overall the outer layer of the boundary layer enters into a transient decelerating regime, while the inner layer and the turbine region attain a new statistically steady equilibrium within approximately one wind-farm through-flow time. Two additional optimal control cases study penalization of turbulent dissipation. For the current wind-farm geometry, it is found that the ratio between wind-farm energy extraction and turbulent boundary-layer dissipation remains roughly around 70 %, but can be slightly increased by a few per cent by penalizing the dissipation in the optimization objective. For a pressure-driven boundary layer in equilibrium, we estimate that such a shift can lead to an increase in wind-farm energy extraction of 6 %.

AbstractThe science cases for incorporating high time resolution capabilities into modern radio telescopes are as numerous as they are compelling. Science targets range from exotic sources such as pulsars, to our Sun, to recently detected possible extragalactic bursts of radio emission, the so-called fast radio bursts (FRBs). Originally conceived purely as an imaging telescope, the initial design of the Murchison Widefield Array (MWA) did not include the ability to access high time and frequency resolution voltage data. However, the flexibility of the MWA’s software correlator allowed an off-the-shelf solution for adding this capability. This paper describes the system that records the 100 μs and 10 kHz resolution voltage data from the MWA. Example science applications, where this capability is critical, are presented, as well as accompanying commissioning results from this mode to demonstrate verification.
Microbiological bioassay usingBacillus pumilusto detect tetracycline in milk
Authors: Tumini Melisa , Nagel Orlando Guillermo , Althaus Rafael Lisandro 
Published: February 2015

The tetracyclines (TCs) are widely used in the treatment of several diseases of cattle and their residues may be present in milk. To control these residues it is necessary to have available inexpensive screening methods, user-friendly and capable of analysing a high number of samples. The purpose of this study was to design a bioassay of microbiological inhibition in microtiter plates with spores ofBacillus pumilusto detect TCs at concentrations corresponding to the Maximum Residue Limits (MRLs). Several complementary experiments were performed to design the bioassay. In the first study, we determined the concentration of spores that produce a change in the bioassay's relative absorbance in a short time period. Subsequently, we assessed the concentration of chloramphenicol required to decrease the detection limit (DL) of TCs at MRLs levels. Thereafter, specificity, DL and cross-specificity of the bioassay were estimated. The most appropriate microbiological inhibition assay had aB. pumilusconcentration of 1·6 × 109 spores/ml, fortified with 2500 μg chloramphenicol/l (CAP) in Mueller Hinton culture medium using brilliant black and toluidine blue as redox indicator. This bioassay detected 117 μg chlortetracycline/l, 142 μg oxytetracycline/l and 105 μg tetracycline/l by means of a change in the indicator's colour in a period of 5 h. The method showed good specificity (97·9%) which decreased slightly (93·3%) in milk samples with high somatic cell counts (>250 000 cells/ml). Furthermore, other antimicrobials studied (except neomycin) must be present in milk at high concentrations (from >5 to >100 MRLs) to produce positive results in this assay, indicating a low cross specificity.
Acute neonatal respiratory distress caused by a lingual thyroid: the role of nasendoscopy and medical treatment
Authors: Lane L , Prudon S , Cheetham T , Powell S 
Published: February 2015

AbstractBackground:A lingual thyroid is a known cause of oropharyngeal obstruction in the neonate. It can be asymptomatic, or present as stridor, dysphonia, dysphagia or dyspnoea with faltering growth. The therapeutic options include surgical resection.Case report:A 6-day-old female neonate, born at 36 weeks gestation, presented with stridulous breathing and poor feeding. Although the cause was initially thought to be laryngomalacia, nasendoscopy revealed a lingual thyroid. The baby had deranged thyroid function, as detected on neonatal screening, but this result was not available until a later date. Despite being symptomatic, the patient was managed medically; thyroxine therapy was associated with resolution of the respiratory symptoms.Conclusion:Nasendoscopy provides valuable information about an ectopic thyroid gland. Thyroid replacement therapy may help to suppress the size of the ectopic gland and ultimately prevent an unnecessary surgical procedure.
Ethics of Nature in Indian Environmental History: A Review Article
Authors: SIVARAMAKRISHNAN K. 
Published: February 2015

AbstractThis article considers the formation of moral and ethical worlds in India, drawing largely on cases reporting on modern times, as people interact with or imagine the landscapes in which they live. Questions of ethics, and how they are animated in practical existence through the experience of emotional ties and affective attachments to nature, near and far, have not always informed the writing of environmental history in India. In contrast, scholars in disciplines other than history have often paid attention to ethical and religious ideas about landscape and nature. This review argues that ethics of nature are developed in historical processes of community formation and identity-expression or self-making that occur in and through the imagination and experience of the natural world in religious and political action. Historical perspectives on these topics are useful and necessary, even as careful examination of how affect and worship shape attitudes to being in particular landscapes can enrich the understanding of meaningful relations to landscape and nature in environmental history. The argument is developed by a close examination of a handful of recent studies that have provided an empirical basis for this synthesis, review, and conceptual elaboration of the ethics of nature in India. The article considers the formation of ethical ideas and practical values of nature in realms of worship, natural resources management, rural development, conservation science, natural resources policy, and legal disputes relating to nature protection in India.

AbstractIntroductionThere is no consensus on where automated external defibrillators (AEDs) should be placed in rural communities to maximize impact on survival from cardiac arrest. In the community of Stokes County, North Carolina (USA) the Emergency Medical Services (EMS) system promotes cardiopulmonary resuscitation (CPR) public education and AED use with public access defibrillators (PADs) placed mainly in public schools, churches, and government buildings.Hypothesis/ProblemThis study tested the utilization of AEDs assigned to first responders (FRs) in their private-owned-vehicle (POV) compared to AEDs in fixed locations.MethodsThe authors performed a prospective, observational study measuring utilization of AEDs carried by FRs in their POV compared to utilization of AEDs in fixed locations. Automated external defibrillator utilization is activation with pads placed on the patient and analysis of heart rhythm to determine if shock/no-shock is indicated. The Institutional Review Board of Wake Forest University Baptist Health System approved the study and written informed consent was waived. The study began on December 01, 2012 at midnight and ended on December 01, 2013 at midnight.ResultsDuring the 12-month study period, 81 community AEDs were in place, 66 in fixed locations and 15 assigned to FRs in their POVs. No utilizations of the 66 fixed location AEDs were reported (0.0 utilizations/AED/year) while 19 utilizations occurred in the FR POV AED study group (1.27 utilizations/AED/year; P<.0001). Odds ratio of using a FR POV located AED was 172 times more likely than using a community fixed-location AED in this rural community.DiscussionPlacing AEDs in a rural community poses many challenges for optimal utilization in terms of cardiac arrest occurrences. Few studies exist to direct rural community efforts in placing AEDs where they can be most effective, and it has been postulated that placing them directly with FRs may be advantageous.ConclusionsIn this rural community, the authors found that placing AED devices with FRs in their POVs resulted in a statistically significant increase in utilizations over AED fixed locations.NelsonRD, BozemanW, CollinsG, BooeB, BakerT, AlsonR.

Abstract. Cognitive fusion can be defined as the inability to view thoughts as just thoughts, which is hypothesized to increase the impact of those thoughts on behavior. Cognitive fusion is a core concept of Acceptance and Commitment Therapy, a therapeutic approach that is being increasingly studied as a treatment for a plethora of chronic health problems. The objective of this study was to evaluate the psychometric properties of the Cognitive Fusion Questionnaire (CFQ) in a sample of adolescents. Three hundred eight adolescents (11–20 years) completed the Catalan version of the questionnaire (CFQ-C) as well as measures assessing anxiety sensitivity and acceptance. The results supported a one-factor solution for the CFQ-C, and indicated an adequate level of internal consistency (Cronbach’s α = 0.79). The validity of the CFQ-C was supported by a significant positive association between the CFQ-C total score and the measure of anxiety sensitivity and by a significant negative association with the measure of acceptance. The findings support the psychometric properties of the CFQ to study the role that cognitive fusion may play in functioning among adolescents.

AbstractThe Three Gorges Dam has significantly altered ecological and environmental conditions within the reservoir region, but how these changes affect bacterioplankton structure and function is unknown. Here, three widely accepted metagenomic tools were employed to study the impact of damming on the bacterioplankton community in the Xiangxi River. Our results indicated that bacterioplankton communities were both taxonomically and functionally different between backwater and riverine sites, which represent communities with and without direct dam effects, respectively. There were many more nitrogen cycling Betaproteobacteria (e.g., Limnohabitans) and a higher abundance of functional genes and KEGG orthology (KO) groups involved in nitrogen cycling in the riverine sites, suggesting a higher level of bacterial activity involved in generating more nitrogenous nutrients for the growth of phytoplankton. Additionally, the KO categories involved in carbon and sulfur metabolism, as well as most of the detected functional genes also showed clear backwater and riverine patterns. As expected, these diversity patterns all significantly correlated with environmental characteristics, confirming that the bacterioplankton communities in the Xiangxi River were really affected by environmental changes from the Three Gorges Dam. This study provides a first comparative metagenomic insight for evaluating the impacts of the large dam on microbial function.
Analysis of the effects of evaporative cooling on the evaporation of liquid droplets using a combined field approach
Authors: Xu Xuefeng , Ma Liran 
Published: February 2015

AbstractDuring liquid evaporation, the equations for the vapor concentration in the atmosphere and for the temperature in the liquid are coupled and must be solved in an iterative manner. In the present paper, a combined field approach which unifies the coupled fields into one single hybrid field and thus makes the iteration unnecessary is proposed. By using this approach, the influences of the evaporative cooling on the evaporation of pinned sessile droplets are investigated and its predictions are found in good agreement with the previous theoretical and experimental results. A dimensionless number Ec which can evaluate the strength of the evaporative cooling is then introduced and the results show that both the evaporation flux along the droplet surface and the total evaporation rate of the droplet decrease as the evaporative cooling number Ec increases. For drying droplets, there exists a critical value EcCrit below which the evaporative cooling effect can be neglected and above which the significance of the effect increases dramatically. The present work may also have more general applications to coupled field problems in which all the fields have the same governing equation.
