Broadband imaging via direct inversion of blended dispersed source array data
Authors: Caporal Matteo , Blacquière Gerrit , Davydenko Mikhail 
Published: September 2017

ABSTRACTAlthough seismic sources typically consist of identical broadband units alone, no physical constraint dictates the use of only one kind of device. We propose an acquisition method that involves the simultaneous exploitation of multiple types of sources during seismic surveys. It is suggested to replace (or support) traditional broadband sources with several devices individually transmitting diverse and reduced frequency bands and covering together the entire temporal and spatial bandwidth of interest. Together, these devices represent a so‐called dispersed source array.As a consequence, the use of simpler sources becomes a practical proposition for seismic acquisition. In fact, the devices dedicated to the generation of the higher frequencies may be smaller and less powerful than the conventional sources, providing the acquisition system with increased operational flexibility and decreasing its environmental impact. Offshore, we can think of more manageable boats carrying air guns of different volumes or marine vibrators generating sweeps with different frequency ranges. On land, vibrator trucks of different sizes, specifically designed for the emission of particular frequency bands, are preferred. From a manufacturing point of view, such source units guarantee a more efficient acoustic energy transmission than today's complex broadband alternatives, relaxing the low‐ versus high‐frequency compromise. Furthermore, specific attention can be addressed to choose shot densities that are optimum for different devices according to their emitted bandwidth. In fact, since the sampling requirements depend on the maximum transmitted frequencies, the appropriate number of sources dedicated to the lower frequencies is relatively small, provided the signal‐to‐noise ratio requirements are met. Additionally, the method allows to rethink the way to address the ghost problem in marine seismic acquisition, permitting to tow different sources at different depths based on the devices' individual central frequencies. As a consequence, the destructive interference of the ghost notches, including the one at 0 Hz, is largely mitigated. Furthermore, blended acquisition (also known as simultaneous source acquisition) is part of the dispersed source array concept, improving the operational flexibility, cost efficiency, and signal‐to‐noise ratio.Based on theoretical considerations and numerical data examples, the advantages of this approach and its feasibility are demonstrated.

SummaryBacteriophages infecting major groups of freshwater heterotrophic bacteria have been rarely isolated, hampering analyses of freshwater viromes. Here, we report the isolation and genomic characterization of P19250A, the first phage that infects the LD28 clade, an abundant freshwater methylotrophic bacterial group. P19250A was isolated from Lake Soyang, an oligotrophic reservoir, using an LD28 strain as a host. Morphological and genomic analyses revealed that P19250A is a lytic siphovirus with a ∼38.6‐kb genome. To analyze the distribution of P19250A genome within its habitat, six seasonal viral metagenome (virome) samples were prepared from Lake Soyang. Through binning analysis of freshwater viromes, P19250A was shown to be the most highly assigned freshwater phage that infects heterotrophic bacteria (up to 8.21%) in five viromes. Furthermore, when freshwater virome data collected worldwide were analyzed, P19250A genome also showed high abundance, especially in Lough Neagh, UK, where P19250A genome was recorded as the most abundant bacteriophage. From metagenome analysis, the proportion of P19250A‐assigned reads showed seasonal fluctuation following the abundance of the LD28 clade in Lake Soyang. These results showed that P19250A would be an essential resource for analyses of freshwater viromes, and also suggest that phages of other abundant freshwater bacteria need to be isolated for better understanding of freshwater viruses.

PURPOSETo determine the acceptability, usefulness, and ease of use for four nursing clinical decision support interface prototypes.METHODSIn a simulated hospital environment, 60 registered nurses (48 female; mean age = 33.7 ± 10.8; mean years of experience = 8.1 ± 9.7) participated in a randomized study with four study groups. Measures included acceptability, usefulness, and ease of use scales.FINDINGSMean scores were high for acceptability, usefulness, and the ease of use for all four groups. Inexperienced participants (<1 year) reported higher perceived ease of use (p = .05) and perceived usefulness (p = .01) than those with experience of 1 year or more.CONCLUSIONSParticipants completed the protocol and reported that all four interfaces, including the control (HANDS), were acceptable, easy to use, and useful.IMPLICATIONS FOR NURSING KNOWLEDGEFurther study is warranted before clinical implementation within the electronic health record.
Maternal intelligence quotient (IQ) predicts IQ and language in very preterm children at age 5 years

Published: September 2017

BackgroundSociodemographic factors are linked to cognitive outcomes in children born very preterm (VPT; ≤30 weeks gestation). The influence of maternal intellectual ability, a heritable trait, is unknown. Also undetermined is the extent to which associations between maternal and child intellectual ability vary according to parenting behaviors that target cognitive stimulation in the home.MethodsAt age 5 years, 84 VPT and 38 demographically matched full‐term (FT) children underwent neurodevelopmental assessment. Children's intellectual ability was assessed using The Wechsler Preschool Primary Scale of Intelligence‐III, and language was assessed with the Clinical Evaluation of Language Fundamentals Preschool‐2. The Wechsler Test of Adult Reading estimated maternal intellectual ability. The StimQ‐Preschool questionnaire provided a measure of cognitive stimulation in the home. Linear mixed‐effects models examined independent effects and interactions between maternal intellectual ability and cognitive stimulation on children's outcomes.ResultsAfter covariate adjustment, maternal intellectual ability was associated with child intellectual (p < .001) and language (p = .002) abilities. Stronger associations were observed in FT mother–child dyads (B = .63, p = .04) than VPT dyads (B = .42, p = .01). Mothers of VPT children reported lower levels of Parental Involvement in Developmental Advance (p = .007) and Parental Verbal Responsiveness (p = .04). Group differences in Parental Involvement in Developmental Advance, but not Parental Verbal Responsivity, persisted after adjusting for social background (p = .03). There was no evidence of an interaction between maternal intellectual ability and Parental Involvement in Developmental Advance (p = .34). Instead, maternal intellectual ability (p < .001) and Parental Involvement in Developmental Advance (p = .05) independently predicted VPT children's outcomes.ConclusionsMaternal intellectual ability is an important trait linked to VPT and FT children's intellectual and language outcomes. Prematurity increases variation in the heritability of intellectual ability and shifts children from the expected range based on maternal ability. Parental involvement in activities that help children master new skills may promote cognitive development in VPT children born to mothers of lower intellectual ability.
Using the robust design framework and relative abundance to predict the population size of pallid sturgeon Scaphirhynchus albus in the lower Missouri River

Published: September 2017

Several population viability models were constructed to aid recovery in endangered Scaphirhynchus albus, but these models are dependent upon accurate and precise input parameters that are not provided with standard catch per unit effort (CPUE) indices. Nine years of sampling efforts, under the robust design framework, provided 1223 unique captures with an 18·3% recapture rate. The annual population estimates varied from 4·0–7·3 fish rkm−1 for wild and 8·4–18·4 fish rkm−1 for hatchery‐reared S. albus. The relationship between abundance (N) and annual trot‐line CPUE indices (x = 70.726y + 2·533, R2 = 0·91, P < 0·001) was used to predict an abundance of 13 616 ± 7142 s.e. S. albus in the lower Missouri River. The use of small‐scale intensive sampling to develop a relationship with relative abundance indices reported here, may provide a framework for other fisheries management applications where large‐scale intensive sampling is not feasible, but catch data are available.

PurposeThe aim of this research is to adapt and validate a perinatal depression and anxiety screening tool in Mali, West Africa for use in community‐based maternal mental health prevention interventions.Research QuestionsHow do standardized screening tools for depression and anxiety align with maternal depression and anxiety symptomatology in Mali? Is the adapted depression and anxiety screening tool valid and reliable?SignificanceMidwives in low‐resource settings such as Mali provide the majority of maternal health services with few resources. As with other threats to maternal and newborn well‐being, perinatal depression is a significant cause of morbidity and mortality including poor perinatal outcomes and infant development. However, mental health issues are rarely included in maternal health programming, and local midwives have few tools to address the issue. An important component of maternal care is screening for depression and anxiety with a tool based on local ethnomedical understandings of mental health. Western screening tools have been adapted and validated in other low‐income contexts but not in the Malian context. Such a tool has the potential to provide midwives with a way to identify women who need mental health support.MethodsWe are using a mixed‐methods study to adapt and validate a postpartum depression and anxiety screening tool using the DIME Program Research Model: Design, Implementation, Monitoring, and Evaluation. Focus groups and interviews conducted in Sélingué, Mali in 2016 provided local terms and symptomatology upon which to base the adaptation of screening tools. A pretest was conducted among local midwives in Sélingué in June 2016, and additional pretests with community women are ongoing; additional interviews to establish reliability and validity with childbearing women took place in September of 2016.ResultsTo date, multiple elements of the Edinburgh Postnatal Depression Scale and Hopkins Symptom Checklist were expressed locally. Some elements from established screeners were not locally relevant, and new elements were added to the adapted tool.DiscussionPerinatal depression in low‐resource settings requires locally relevant screening tools. Such tools are necessary for community‐based efforts to integrate perinatal depression screening, prevention, and intervention into routine care in Mali.

Published: September 2017

PurposeTo identify and compare the perception of professional empowerment among midwifery students according to the type of curriculum.Research QuestionDuring 2009, a Competence Based Education (CBE) curriculum was implemented in the School of Midwifery, University of Chile to determine if this curriculum is effective in improving professional empowerment.SignificanceStudies of health care professionals note that the quality and safety of patient care is directly related to the degree of provider empowerment. Provider empowerment influences plans of care and contributes to the decision‐making outcomes of the multidisciplinary team. Studies carried out in Chile revealed that midwifery professionals employed in maternity units do not feel empowered enough to face a hierarchical and medicalized health system; moreover, midwifery students reported lack of self‐confidence among midwives working at Primary Health Care (PHC) clinics to address the prevalent and complex psychosocial problems affecting many women. Empowerment must be addressed during preservice education, and it is therefore a central aspect of curricula.MethodsA structured online interview was conducted among a sample of 147 midwifery graduates of 2 different curricula (content and competency based vs CBE) of the School of Midwifery at the University of Chile, through an adaptation of the Perceptions Midwifery Empowerment Scale (PEMS) developed by Matthews (2009), translated by the backward‐translation technique, and tested in 10 midwives working in the maternity unit at the Clinical Hospital of the University of Chile, selected by convenience. This instrument comprises 3 domains: autonomous practice, effective management, and women‐centered practice. The study was approved by the ethics committee at the Faculty of Medicine, University of Chile.ResultsGlobally, over 80% of the respondents revealed optimal levels of professional empowerment. According to the domains, those providing woman‐centered care reported the higher scores, and those who graduated from the CBE curriculum scored equally well at one‐year post graduation in comparison to those graduates with 5 years or more of clinical experience.DiscussionStudying empowerment becomes very useful in the development of a competent professional to promote woman‐centered practice. These findings suggest the positive influence of CBE in enhancing professional empowerment; however, further and accurate assessment is required to complement these outcomes.
Drug repurposing may generate novel approaches to treating depression
Authors: Ebada Mohamed Elsaed 
Published: September 2017

Abstract

Objectives
The breakthrough advancements in scientific medical research have greatly improved our understanding of the pathogenesis of depression, encouraging drug discoverers to take a shorter path than ever through drug repurposing to generate new antidepressant medications. In addition to reduced noradrenergic and serotonergic neurotransmission in the brain, other coincidence features such as glutamate neurotoxicity, inflammation and/or cerebrovascular insufficiency are implicated in the pathogenesis of major depressive disorder and late-life depression. This short review discusses the progress made in repurposing drugs for antidepressant actions.

Key findings
Drugs being repurposed as antidepressants act on novel drug targets, thereby treating resistant depression and improving remission rate. Drugs such as ketamine, dextromethorphan/quinidine and scopolamine are rapidly acting antidepressants targeting glutamate receptors. Nimodipine and quetiapine are efficient add-on therapy for late-life depression. Anti-inflammatory drugs, statins, insulin sensitizers, minocycline could remarkably contribute to treating refractory depression.

Summary
Drug repurposing represents an alternative approach to cope with major obstacles, including financial insufficiency and unavoidable long lag evaluation time, undermining the classical pathway of developing new hit compounds into clinically approved antidepressants.
Cladocera assemblages from reservoirs in Sri Lanka and their relationship to measured limnological variables
Authors: Yatigammana S. K. , Cumming B. F. 
Published: September 2017

AbstractThe potential of using surface‐sediment assemblages of Cladocera as bioindicators for reservoirs in Sri Lanka was assessed for their subfossil remains, along with contemporary physical and chemical measurements from each reservoir. The reservoirs span five climatic regions, from extremely arid environments to tropical montane forests, as well as three orders of magnitude changes in many physical and chemical variables. In total, although the remains of 39 Cladocera taxa from 21 genera were identified, only 31 taxa from 37 sites were present at sufficiently high abundances to assess their relation to measured environmental variables. Canonical correspondence analysis (CCA) identified surface area, maximum depth and chloride as the three most important measured environmental variables that could account for the variation in the cladoceran assemblages. Taxa such as Chydorus sphaericus, Alona aff. verrucosa and Leydigia acanthocercoides were more abundant in generally deeper, larger reservoirs, whereas Alonella excisa, Euryalona orientalis, Notoalona globulosa and Chydorus eurynotus were more abundant in shallow smaller reservoirs. Although there was a strong separation between climatic zones in terms of factors related to specific conductance, this factor only appears marginally important in separating cladoceran assemblages. Quantitative inference models developed to assess the strength of inferring environmental variables using partial least squares regression and calibration were all relatively weak, with jackknifed coefficient of determination values of 0.40, 0.28 and 0.27 for surface area, maximum depth and chloride, respectively. These results, in conjunction with large differences in eigenvalues between constrained and unconstrained ordinations, suggest that unmeasured environmental variables are also important in structuring cladoceran assemblages.

Published: September 2017

AbstractGillnet selectivity is crucial for the effective and sustainable management of fisheries. However, there is inadequate information on gillnet selectivity for commercially important species in Tono Reservoir. To facilitate the sustainable exploitation of fish species, this study was conducted to estimate the selectivity parameters of commonly used monofilament gillnets for commercially important fish species in Tono Reservoir from January 2015 to June 2016. Two common nylon monofilament gillnets used by fishermen in Tono Reservoir with stretched mesh sizes 5 and 7 cm and equal dimensions were placed in the same fishing area and retrieved within 12 h. The fish catches were assessed, and selectivity parameters for Sarotherodon galilaeus, Oreochromis niloticus, Coptodon zillii, Clarias gariepinus and Auchenoglanis occidentalis were estimated using the Holt model. The catch per unit effort of the two gillnets exhibited no significant difference. The optimum total lengths of capture of four fish species excluding C. zillii ranged from 13.53 to 25.43 cm for the 5 cm gillnet, and 18.95 to 35.60 cm for the 7 cm gillnet. Common selection factors varied from 2.71 to 5.09. The mean total length at first sexual maturity for all five fish species ranged from 8.60 to 28.86 cm. Both the 5 and 7 cm gillnets were found to be inappropriate for use in the reservoir. Accordingly, their use should be discouraged to protect juvenile fish so that the sustainable exploitation and conservation of fish species in this multispecies fishery can be achieved.
ACA Exchange Competitiveness in Florida
Authors: Born Patricia 
Published: September 2017

AbstractFlorida chose not to develop its own marketplace and therefore hosts the federally facilitated marketplace, HealthCare.gov. While the state may have had an opportunity to define rating areas, it defaulted to the county level, which is the level at which agents and carriers are licensed to conduct business. This resulted in 67 rating areas, which is significantly more than most other states. South Carolina has 46 rating areas, and Texas has 26. All other states have fewer than 20.

We report on associations of retrospectively reported temporally prior mental disorders and Army career characteristics with subsequent first onset of suicidal behaviors in a large, representative sample of US Army soldiers who participated in the Consolidated All‐Army Survey of the Army Study to Assess Risk and Resilience in Servicemembers (N = 29,982). Results reveal that among men and women, all self‐reported lifetime disorders measured (some assessed with screening scales) are associated with subsequent onset of suicide ideation. Among men, three disorders characterized by agitation and impulsiveness (intermittent explosive disorder, panic disorder, and substance disorders) predict the transition from suicide ideation to attempt. For both men and women, being in the Regular Army (vs. National Guard or Army Reserve) predicts suicide attempts in the total sample. For men, a history of deployment and junior rank are predictors of suicide attempts after adjusting for preenlistment disorders but not accounting for pre‐ and postenlistment disorders, suggesting that postenlistment disorders account for some of the increased suicide risk among these career characteristics. Overall, these results highlight associations between mental disorders and suicidal behaviors, but underscore limitations predicting which people with ideation attempt suicide.
