AbstractBACKGROUNDIn order to reduce application dosage of carbendazim (CBD), the effects of different droplet sizes and application rate on initial deposition, retention rate, and field control efficacy of CBD in the pepper plant (Capsicum annuum L.) were studied under laboratory and field conditions.RESULTSBased on eight types of nozzles at six concentrations of 646.8, 582.2, 517.5, 414.0, 310.5, and 258.7 g a.i./hm2, the initial deposition amount of CBD in the pepper plant showed a first increased and then decreased trend with the increasing application dosages. The initial deposition amount of CBD in the pepper leaves and stems was highest when using the nozzle ST110‐03 at 200 μm volume median diameter (VMD) and 350 L/hm2 application rate. HPLC‐MS/MS analysis revealed that CBD was first converted to 2‐aminobenzimidazole, which then transformed into benzimidazole and 2‐hydroxybenzimidazole by deamination and hydroxylation, and ultimately mineralized to carbon dioxide and water via the cleavage of the imidazole ring in pepper plant. The dissipation rate of CBD was fruits > roots/stems > leaves > soils. After 7 days of application, the field efficacy of CBD at six concentrations on pepper anthracnose (Colletotrichum spp.) were 94.1%, 91.3%, 82.3%, 76.5%, 47.0%, and 41.2%, respectively.CONCLUSIONThe results revealed the deposition and dissipation characteristics of CBD, and the minimum effective dosage on pepper anthracnose decreased to 80% of the minimum recommended dose in the open field pepper ecosystem. The study will contribute to the CBD reduction by improving its utilization rate in the pepper‐field ecosystem. © 2019 Society of Chemical Industry
Electronic effect of β‐diketonato ligands on the redox potential of fac and mer tris(β‐diketonato) iron(III) complexes: A density functional theory study and molecular electrostatic potential analysis
Authors: Adeniyi Adebayo A. , Conradie Jeanet 
Published: August 2019

AbstractExperimental redox potentials of 16 derivatives of tris(β‐diketonato)iron(III) complexes (where β‐diketonato(R1COCHCOR2)─, with substituents R1 and R2 in different combinations of H, C4H3S, C4H3O, CH3, Ph, CF3, or C (CH3)3), and 11 additional isomers, were studied theoretically in terms of the electronic properties, substituent effects, electron affinity, and molecular electrostatic potential (MESP) analysis, using density functional theory methods. The computational methods reproduced the experimental reduction potential to a very high level of accuracy, especially when the M062X functional was used (with mean absolute deviation [MAD] = 0.054 and 0.093 and correlation R2 = 0.978 and 0.981 obtained by application of two slightly different free energy cycles, respectively). The most negative computed reduction potential corresponds to the most negative reported experimental reductions, which is indicative of the least favorable reduction potential, also in most cases the most stable molecules energetically. The calculated reduction potentials of the fac isomers of the molecules were generally higher (less negative) than that of the mer isomers when one of the ligand substituents R1 or R2 was CF3 (M062X results), indicating better ease of reduction, although in many cases, the experimental reduction potential agreed better with the calculated reduction potential of the mer isomer instead. The calculated reduction potentials were also affected by the substituents in the order of CF3 > H > C4H3S > C4H3O > Ph > CH3 > C(CH3)3 (the most negative value). The stronger the electron withdrawing tendency of the substituent, the more favorable (less negative value) the reduction potential becomes. In relation to the CH3‐substituted molecule 1 as a reference, the molecules with electron withdrawing substituents resulted in an electron‐deficient MESP iso‐surface, in both the neutral state and reduced state. All the molecules in their reduced state were characterized with an electron‐deficient MESP iso‐surface compared with the reduced CH3‐substituted molecule 1, with the deficiency increasing in mer compared with fac, for both the neutral and reduced molecules. The relative MESP values of ΔVFe in the reduced state of the molecules were able to predict the corresponding experimental reduction potential to a significant level of accuracy (with MAD = 0.091).

Published: August 2019

AbstractUnderstanding the interactions between contributory factors associated with accidents is important. However, the widely applied Swiss cheese model (SCM) and the human factors analysis and classification system (HFACS) oversimplify the causes of accidents and ignore the interactions among the various components of an entire system, which is the essence of systems thinking. A new systems‐based accident model that reflects the nature of the accidents and can be explained by the underlying accident model must therefore be developed. This study aims to create a new accident model that represents the interactions between the contributory factors, which can offer a systems approach to conducting a comprehensive examination of accidents. We use data obtained from the official accident reports on 94 extraordinary major coal mining catastrophes that took place from 1997 to 2011 in China. The results reveal that all latent conditions, including external factors, organizational influences, unsafe supervision, and preconditions for unsafe behaviours can influence active failures, that is, unsafe behaviours. However, only the preconditions for unsafe behaviours can influence unsafe behaviours within the SCM and HFACS frameworks. Furthermore, latent conditions can affect each other within the contributory factors interactions model. This study provides a new systems‐based accident model that allows us to examine and explain the relationships and linkages within and between complex sociotechnical systems and identify the common factors and interactions that cross human, external, and organizational factors.
Correlated‐replicate occupancy models for wild turkey gobbling call‐count surveys

Published: August 2019

ABSTRACTGobbling call‐count surveys have been frequently used as a means for monitoring distributions and population trends of eastern wild turkeys (Meleagris gallopavo silvestris). However, gobbling activity can be highly variable and potentially leads to biased estimates if detection probability is left unaccounted for. Occupancy modeling based on detection–nondetection data offers an effective way of exploring changes in species distribution and provides logistical flexibility with sampling design. Recent advances in occupancy modeling have enabled detection probability and inferences about occupancy dynamics to be estimated from transect sampling designs with spatially replicated survey stations, similar to those of gobbling call‐count surveys. We analyzed data collected from 1,815 gobbling call‐count surveys in northern Wisconsin, USA, 2014–2017, to compare multiseason correlated‐replicate occupancy models to standard multiseason models. Model selection results strongly supported multiseason correlated‐replicate models (Σwi = 1.00) over standard multiseason occupancy models. We observed evidence for spatial autocorrelation in local occupancy—probability of local availability was lower when turkeys were unavailable at the previous station ( = 0.18 ± 0.07 [SE]) compared with when turkeys were available ( = 0.79 ± 0.13). Probability of detection was imperfect and varied by time of day (β = −0.503) and wind speed (β = −0.362). Turkeys occurred throughout a variety of habitat conditions, but occupancy was greatest ( = 0.990 ± 0.03) along survey routes with 40–60% forest cover. We fit simulated data to standard occupancy models and correlated replicate models and found occupancy and detection estimates were underestimated by as much as 10% with standard occupancy models, but bias was negligible under the correlated replicate modeling approach. Our findings indicate that transect sampling designs that account for spatial correlation among adjacent survey stations can yield improved estimates of detection and occupancy, and such sampling designs could lead to greater ecological interest in factors that influence species occurrence and patterns of habitat use. Gobbling call‐count surveys in conjunction with occupancy‐based modeling may be useful for assessing reintroduced or natural expanding wild turkey populations at the edge of their range. Additionally, we suggest the combination of gobbling surveys and occupancy modeling is useful for evaluating habitat–occurrence relationships across large‐scale landscapes or state‐based wild turkey management units. © 2019 The Wildlife Society.
Money and credit during normal times and house price booms: evidence from time-frequency analysis
Authors: Ryczkowski Maciej 
Published: August 2019

AbstractI analyse the link between money and credit for twelve industrialized countries in the time period from 1970 to 2016. The euro area and Commonwealth Countries have rather strong co-movements between money and credit at longer frequencies. Denmark and Switzerland show weak and episodic effects. Scandinavian countries and the US are somewhere in between. I find strong and significant longer run co-movements especially around booming house prices for all of the sample countries. The analysis suggests the expansionary policy that cleans up after the burst of a bubble may exacerbate the risk of a new house price boom. The interrelation is hidden in the short run, because the co-movements are then rarely statistically significant. According to the wavelet evidence, developments of money and credit since the Great Recession or their decoupling in Japan suggest that it is more appropriate to examine the two variables separately in some circumstances.

Abstract
Whether subtle differences in the emotional context during threat perception can be detected by multi-voxel pattern analysis (MVPA) remains a topic of debate. To investigate this question, we compared the ability of pattern recognition analysis to discriminate between patterns of brain activity to a threatening versus a physically paired neutral stimulus in two different emotional contexts (the stimulus being directed towards or away from the viewer). The directionality of the stimuli is known to be an important factor in activating different defensive responses. Using multiple kernel learning (MKL) classification models, we accurately discriminated patterns of brain activation to threat versus neutral stimuli in the directed towards context but not during the directed away context. Furthermore, we investigated whether it was possible to decode an individual’s subjective threat perception from patterns of whole-brain activity to threatening stimuli in the different emotional contexts using MKL regression models. Interestingly, we were able to accurately predict the subjective threat perception index from the pattern of brain activation to threat only during the directed away context. These results show that subtle differences in the emotional context during threat perception can be detected by MVPA. In the directed towards context, the threat perception was more intense, potentially producing more homogeneous patterns of brain activation across individuals. In the directed away context, the threat perception was relatively less intense and more variable across individuals, enabling the regression model to successfully capture the individual differences and predict the subjective threat perception.
Making Archaeological Collections Available for Research: Recommendations for Repositories
Authors: King Julia A. , Samford Patricia 
Published: August 2019

AbstractArchaeological collections repositories have two principal aims: preserving collections while also making them accessible. This accessibility is critical for the growing number of researchers turning to collections to study the past. This article describes steps that repositories can take to enhance access to collections in their custody, based on the experience of the Maryland Archaeological Conservation Laboratory, the state's public archaeological curation facility. These steps include the identification of stakeholders—archaeologists, Native American tribes, and stakeholder communities; creation of a detailed and prioritized collection inventory including artifacts and records; development of finding aids; reconstruction of provenience systems; and exploration of the digital delivery of collection information. For repositories ill equipped to hold archaeological collections, consideration should be given to transferring the collection to one with the appropriate resources and expertise.
Is depression associated with pathways to care and diagnosis delay in people with tuberculosis in Ethiopia?

Published: August 2019

Background.Co-morbid depression is common in people with tuberculosis (TB). Symptoms of depression (low energy, impaired concentration, decreased motivation and hopelessness) may affect help-seeking; however, this impact has not been studied so far. The objectives of this study were to assess the impact of co-morbid depression on diagnostic delay, pathways to care, and to identify if it mediates other factors associated with diagnostic delay.Methods.We analyzed cross-sectional data collected from 592 adults with newly diagnosed TB. We assessed probable depression using Patient Health Questionnaire, nine items (PHQ-9) at a cut-off 10. Data on diagnosis delay, pathways to TB care, socio-demographic variables, stigma, types of TB, substance use, co-morbid chronic illnesses, and perception about TB were assessed using a structured questionnaire. Generalized structural equation modelling was used to analyze the data.Results.A total of 313 (52.9%) participants had probable depression. Pathway to TB care was direct for 512 (86.5%) of the participants and indirect for 80 (13.5%) of them. The median diagnosis delay was 12.0 weeks. Depression did not have a statistically significant association with pathways to TB care (β= −0.45; 95% CI−1.85 to 0.96) or diagnostic delay [adjusted odds ratio (AOR) = 0.90; 0.77–1.06]. Indirect pathway to TB care was positively associated with diagnosis delay (AOR = 2.72; 95% CI 1.25–5.91).Conclusions.People with TB who had co-morbid probable depression visited the modern health care as directly as and as soon as those without co-morbid depression. How socio-demographic factors influence pathways to care and diagnosis delay require qualitative exploration.

AbstractMore than 130 late Pleistocene trackway sites from the coastal eolianites and beach deposits of the Cape south coast, South Africa, have previously mostly yielded tracks of large mammals and birds. However, two sites east of Still Bay, and a third near Garden Route National Park, yield distinctive trackways of hatchling sea turtles, made during the short posthatching (postemergence) interval when the trackmakers headed for the sea. One assemblage of approximately parallel trackways indicates smaller loggerhead turtle hatchlings, with alternating gaits, and contrasts with a wider trackway indicating a leatherback turtle hatchling. These are the world's first reports of fossil traces that document this brief “run-for the-sea” phenomenon. They help delineate late Pleistocene sea turtle breeding ranges and indicate climatic conditions along the Cape south coast. Ichnotaxonomically defined swim tracks of large adult sea turtles are known from a few Mesozoic sites. Likewise, walking and swim traces of terrestrial freshwater turtles are also known from the Mesozoic and Cenozoic. However, as no ichnotaxonomy exists for these diagnostic hatchling trails, we assign the trackways of the inferred loggerheads to the new ichnotaxonAustralochelichnus agulhasiiichnogen. et ichnosp. nov., and the inferred leatherback trackway toMarinerichnus latusichnogen. et ichnosp. nov.

AbstractAimsRefugees are confronted with the task of adapting to the long-term erosion of psychosocial systems and institutions that in stable societies support psychological well-being and mental health. We provide an overview of the theoretical principles and practical steps taken to develop a novel psychotherapeutic approach, Integrative Adapt Therapy (IAT), which aims to assist refugees to adapt to these changes. This paper offers the background informing ongoing trials of IAT amongst refugees from Myanmar.MethodsA systematic process was followed in formulating the therapy and devising a treatment manual consistent with the principles of the Adaptation and Development After Persecution and Trauma (ADAPT) model. The process of development and refinement was based on qualitative research amongst 70 refugees (ten from West Papua and 60 Rohingya from Myanmar). The therapeutic process was then piloted by trained interventionists amongst a purposively selected sample of 20 Rohingya refugees in Malaysia.ResultsThe final formulation of IAT represented an integration of the principles of the ADAPT model and evidence-based techniques of modern therapies in the field, including a transdiagnostic approach and the selective use of cognitive behavioural treatment elements such as problem-solving and emotional regulation techniques. The steps outlined in refining the manual are outlined in relation to work amongst West Papuan refugees, and the process of cultural and contextual modifications described during early piloting with Rohingya refugees in Malaysia.ConclusionsIAT integrates universal principles of the ADAPT model with the particularities of the culture, history of conflict and living context of each refugee community; this synthesis of knowledge forms the basis for participants gaining insights into their personal patterns of psychosocial adaptation to the refugee experience. Participants then apply evidence-based techniques to improve their capacity to adapt to the serial psychosocial changes they have encountered in their lives as refugees. The overarching goal of IAT is to provide refugees with a coherent framework that assists in making sense of their experiences and their emotional and interpersonal reactions to the challenges they confront within the family and community context. As such, the principles of a general model (ADAPT) are used as a springboard for making concrete, manageable and meaningful life changes at the individual level, a potentially novel approach for psychosocial interventions in the field.

AbstractThe ionospheric electron temperature is important for determining the neutral/photochemical escape rate from the Martian atmosphere via the dissociative recombination of O2+. The Langmuir Probe and Waves instrument onboard MAVEN (Mars Atmosphere and Volatile EvolutioN) measures electron temperatures in the ionosphere. The current paper studies electron temperatures in the dayside for two regions where (1) crustal magnetic fields are dominant and (2) draped magnetic fields are dominant. Overall, the electron temperature is lower in the crustal‐field regions, namely, the strong magnetic field region, which is due to a transport of cold electrons along magnetic field lines from the lower to upper atmosphere. The electron temperature is also greater for high solar extreme ultraviolet conditions, which is associated with the local extreme ultraviolet energy deposition. The current models underestimate the electron temperature above 250‐km altitude in the crustal‐field region. Electron heat conduction associated with a photoelectron transport in the crustal‐field regions is altered due to kinetic effects, such the magnetic mirror and/or ambipolar electric field because the electron mean free path exceeds the relevant length scale for electron temperature. The mirror force can affect the electron and heat transport between low altitudes, where the neutral density and related electron cooling rates are the greatest, and high altitudes, while the ambipolar electric field decelerates the electron's upward motion. These effects have not been included in current models of the electron energetics, and consideration of such effects on the electron temperature in the crustal‐field region should be considered for future numerical simulations.
Sea Level Rise Explains Changing Carbon Accumulation Rates in a Salt Marsh Over the Past Two Millennia

Published: August 2019

AbstractHigh rates of carbon burial observed in wetland sediments have garnered attention as a potential “natural fix” to reduce the concentration of carbon dioxide (CO2) in Earth's atmosphere. A carbon accumulation rate (CAR) can be determined through various methods that integrate a carbon stock over different time periods, ranging from decades to millennia. Our goal was to assess how CAR changed over the lifespan of a salt marsh. We applied a geochronology to a series of salt marsh cores using both 14C and 210Pb markers to calculate CARs that were integrated between 35 and 2,460 years before present. CAR was 39 g C·m−2·year−1 when integrated over millennia but was upward of 148 g C·m−2·year−1 for the past century. We present additional evidence to account for this variability by linking it to changes in relative sea level rise (RSLR), where higher rates of RSLR were associated with higher CARs. Thus, the CAR calculated for a wetland should integrate timescales that capture the influence of contemporary RSLR. Therefore, caution should be exercised not to utilize a CAR calculated over inappropriately short or long timescales as a current assessment or forecasting tool for the climate change mitigation potential of a wetland.
