RETRACTED ARTICLE: Likelihood-based GNSS positioning using LOS/NLOS predictions from 3D mapping and pseudoranges
Authors: Groves Paul D. , Adjrad Mounir 
Published: July 2017

Abstract The accuracy of conventional global navigation satellite systems (GNSS) positioning in dense urban areas is severely degraded due to blockage and reflection of the signals by the surrounding buildings. By using 3D mapping of the buildings to aid GNSS positioning, the accuracy can be substantially improved. However, positioning performance must be balanced against computational load. Here, a likelihood-based 3D-mapping-aided (3DMA) GNSS ranging algorithm is demonstrated that enables signals predicted to be non-line-of-sight (NLOS) to contribute to the position solution without explicitly computing the additional path delay due to NLOS reception, which is computationally expensive. Likelihoods for an array of candidate positions are computed based on the difference between the measured and predicted pseudoranges. However, a skewed distribution is assumed for those signals predicted to be NLOS on the basis that the ensuing ranging errors are always positive. An overall position solution is then extracted from the likelihood surface. GNSS measurement data have been collected at several locations in both traditional and modern dense urban environments. Horizontal root-mean-square single-epoch position accuracies of 4.7, 5.6 and 6.5 m are obtained using, respectively, a Leica Viva geodetic receiver, a u-blox EVK M8T consumer-grade receiver and a Nexus 9 tablet incorporating a smartphone GNSS antenna and a GNSS chipset that outputs pseudoranges. The corresponding accuracies using single-epoch conventional GNSS positioning are 20.5, 23.0 and 28.4 m, about a factor of four larger. The 3DMA GNSS algorithms have also been implemented in real time on a Raspberry Pi 3 at a 1-Hz update rate.
Ecological Instability and Children’s Classroom Behavior in Kindergarten
Authors: Fomby Paula , Mollborn Stefanie 
Published: July 2017

AbstractWe engage the concept of ecological instability to assess whether children’s exposure to frequent change in multiple contexts is associated with teacher reports of students’ overall behavior, externalizing behavior, and approach to learning during kindergarten. We operationalize multiple dimensions of children’s exposure to repeated change—including the frequency, concurrency, chronicity, timing, and types of changes children experience—in a nationally representative longitudinal cohort of U.S.-born children (Early Childhood Longitudinal Study-Birth Cohort, N ~ 4,750). We focus on early childhood, a period of substantial flux in children’s family and neighborhood contexts. Predicted behavior scores differ by approximately one-fifth of a standard deviation for children who experienced high or chronic exposure to ecological change compared with those who experienced little or no change. These findings emphasize the distinctiveness of multidomain ecological instability as a risk factor for healthy development that should be conceptualized differently from the broader concept of normative levels of change in early childhood environments.

ABSTRACTThis study tested whether there are linear or nonlinear relations between prenatal/birth cumulative risk and psychosocial outcomes during adolescence. Participants (n = 6963) were taken from the Northern Finland Birth Cohort Study 1986. The majority of participants did not experience any contextual risk factors around the time of the target child's birth (58.1%). Even in this low‐risk sample, cumulative contextual risk assessed around the time of birth was related to seven different psychosocial outcomes 16 years later. There was some evidence for nonlinear effects, but only for substance‐related outcomes; however, the form of the association depended on how the cumulative risk index was calculated. Gender did not moderate the relation between cumulative risk and any of the adolescent psychosocial outcomes. Results highlight the potential value of using the cumulative risk framework for identifying children at birth who are at risk for a range of poor psychosocial outcomes during adolescence.
Professional Development Strategies to Enhance Nurses’ Knowledge and Maintain Safe Practice
Authors: Bindon Susan L. 
Published: July 2017

AbstractMaintaining competence is a professional responsibility for nurses. Individual nurses are accountable for their practice, as outlined in the American Nurses Association's Nursing: Scope and Standards of Practice. Nurses across clinical settings face the sometimes daunting challenge of staying abreast of regulatory mandates, practice changes, equipment updates, and other workplace expectations. In the complex, evolving perioperative setting, professional development is a priority, and the need for ongoing education is critical. However, nurses’ efforts to engage in their own development can be hampered by a lack of time, limited access to educational resources, or cost concerns. This article provides an overview of nursing professional development and offers some resources to help individual nurses maintain or enhance their knowledge, skills, and attitudes.
Introducing Perioperative Nursing as a Foundation for Clinical Practice
Authors: Tschirch Poldi , Leyden Kristina , Dufrene Claudine , Land Sharon 
Published: July 2017

AbstractThis article describes one school's experience in providing a perioperative nursing course as a first clinical course in a bachelor of science in nursing curriculum. This innovation reframes the perspective on perioperative nursing from that of an elective clinical specialty that is not essential to basic nursing education to a practice setting that provides key foundational clinical learning experiences for the novice nursing student. A strong academic‐practice partnership; effective preparation for key stakeholders including nursing staff members, preceptors, and students; and collaboration with AORN were essential elements in the success of this clinical learning innovation. We describe learning outcomes, lessons learned, and future plans for enhancing and expanding this course.
Transitioning From Perioperative Staff Nurse to Perioperative Educator
Authors: Mower Juliana 
Published: July 2017

AbstractPerioperative nurses who enjoy teaching may wish to become staff development educators. The shift to this new role requires a transition period during which the new educator acquires the knowledge, skills, and attitudes integral to mastering the job. A systematic approach to achieving baseline competencies in the educator role helps to ensure a successful conversion from providing direct patient care to supporting the educational needs of staff members.

Colonial Archives or Archival Colonialism?
Authors: Whittington Stephen L. 
Published: July 2017

ABSTRACTDocuments from Oaxaca, Mexico, in archives and museums in Mexico, the United States, and former European colonial powers are stimulating archaeological projects and other research in the areas where they originated. The Teozacoalco Archaeological Project was inspired by colonial-period documents housed in the Nettie Lee Benson Latin American Library at the University of Texas at Austin. Chiyo Cahnu, a Mixtec kingdom better known as Teozacoalco, was the scene of Aztec and Spanish colonial incursions. The archiving in Texas of the famous Mapa de Teozacoalco and associated documents pertaining to the kingdom/municipality, as well as other documents related to Teozacoalco, neighboring Mixtec kingdoms, and other indigenous Oaxacan communities housed in libraries, archives, and museums distant from those communities, invites us to consider some important issues: how and why they left their original homes and arrived in their present locations and legal and ethical ramifications of housing them outside of their homeland. Included in the latter topic are questions about decolonizing documents, whether documents should be repatriated, and best practices for archaeologists whose projects are inspired by them.
From Archaeologist to Archivist
Authors: Wiltshire Kelly 
Published: July 2017

ABSTRACTMoving image archives—like many other archives—are considered a passive repository of knowledge extraction, rather than an active site of knowledge production. Following the premise that archives are indeed a source of knowledge production, this article explores how moving image archives have the potential to produce new and alternative knowledges by bringing to light factors that may have influenced archaeological practice, factors captured within a moving image archive but obscured or marginalized within linear accounts of this practice. While such an archive may exist unevenly, the Australian Institute of Aboriginal and Torres Strait Islander Studies (AIATSIS) has been historically positioned to develop a moving image archive that features a number of well-known archaeological investigations. Yet this archive and similar moving image archives remain overlooked and underutilized resources. In order to address this, emphasis is placed on producing detailed, searchable, and retrievable content description for moving image archives. In doing so, this article maintains that the knowledge and experience brought to the management of this archive following the author's transition “from archaeologist to archivist,” is key to promoting the discoverability and accessibility of this archive with potential clients in the archaeological, academic, and broader community.
The Role of Victimization in Shaping Households’ Preparedness for Armed Conflicts in Israel

Published: July 2017

ABSTRACTObjectivesOne of the most prominent threats to the Israeli population is the risk from armed conflicts. Yet, promoting preparedness behavior proves to be highly difficult. Arguably, this is partially due to the chronic exposure of the Israeli public to this threat, a.k.a. “Victimization.” The purpose of this study was to examine whether victimization plays a prominent role in shaping preparedness behavior toward armed conflicts in Israel.MethodsAn online survey of 502 participants representing the adult Jewish population in Israel was carried out. A set of questionnaires designed to assess public perception of preparedness-affecting factors was used. The list of preparedness-affecting factors was conceptualized by an expert panel before the survey.ResultsThe results suggest that low prioritization and ignoring of civil-defense instructions during routine times are leading causes for non-compliance with preparedness recommendations. Ignoring instructions is also negatively correlated with reported preparedness. Misunderstanding the threat and fearing it also seem to be important factors.ConclusionsThe results of this study support the hypothesis that victimization plays an important role in shaping preparedness behavior toward armed conflicts among Jews in Israel. The findings demonstrate the complexity of the socio-psychological perspective of preparedness behavior in victimized populations. (Disaster Med Public Health Preparedness. 2018;12:67–75)

BackgroundMalaria elimination is on global agendas following successful transmission reductions. Nevertheless moving from low to zero transmission is challenging. South Africa has an elimination target of 2018, which may or may not be realised in its hypoendemic areas.MethodsThe Agincourt Health and Demographic Surveillance System has monitored population health in north-eastern South Africa since 1992. Malaria deaths were analysed against individual factors, socioeconomic status, labour migration and weather over a 21-year period, eliciting trends over time and associations with covariates.ResultsOf 13 251 registered deaths over 1.58 million person-years, 1.2% were attributed to malaria. Malaria mortality rates increased from 1992 to 2013, while mean daily maximum temperature rose by 1.5 °C. Travel to endemic Mozambique became easier, and malaria mortality increased in higher socioeconomic groups. Overall, malaria mortality was significantly associated with age, socioeconomic status, labour migration and employment, yearly rainfall and higher rainfall/temperature shortly before death.ConclusionsMalaria persists as a small but important cause of death in this semi-rural South African population. Detailed longitudinal population data were crucial for these analyses. The findings highlight practical political, socioeconomic and environmental difficulties that may also be encountered elsewhere in moving from low-transmission scenarios to malaria elimination.

SummaryThe oxidation (rancidity) of fat is a very common feed quality issue, which can negatively affect growth performance and meat quality of broilers. Besides other factors, metal ions such as Zn, Cu and Fe can facilitate lipid peroxidation in feed. The objective of the current study was to investigate the effect of feeding corn soy diets containing fresh or oxidised soybean oil with different forms of microminerals on production performance of broiler chicks. Dietary treatments consisted of a 2 × 2 factorial structure with two kinds of soybean oil (oxidised or fresh) and two forms of microminerals (inorganic or organic). Mineral proteinate (Bioplex®, Alltech Inc.) including Zn, Mn, Cu and Fe was used as the organic source and was supplemented at the level equivalent to 25% of an inorganic source in the control diets. Organic selenium (Sel-Plex®, Alltech Inc.) at 0.3 mg/kg of diet was used to replace sodium selenite used at 0.3 mg/kg of diet in control diet. Oxidised soybean oil was prepared by convection heat (90°C for a period of seven days in a convection oven). A total of 1152 one-day old chicks were allotted randomly to the four dietary treatments using 12 replicates of 24 chicks per pen. Chicks were raised in floor pens for 42 days in an environmentally controlled room with free access to feed and water. There was no statistical interaction between oil source and mineral form on performance or mineral content of breast meat. Feeding oxidised oil increased (P < 0.05) feed intake and decreased gain to feed ratio (FCE) of chicks. Supplementation with organic minerals improved (P < 0.05) weight gain and FCE of chicks. The breast meat of chicks fed organic mineral had higher (P < 0.01) Se content than those from the control group. The results indicated that the addition of organic minerals to broiler diets can minimise the negative impact of oxidised oil on the performance of broiler chicks.
Identification and characterization of ace1-type acetylcholinesterase in insecticide-resistant and -susceptible Propylaea japonica (Thunberg)
Authors: Wang M.M. , Xing L.Y. , Ni Z.W. , Wu G. 
Published: July 2017

AbstractCharacterization and gene cloning of acetylecholinesterase (AChE) in the insecticide-resistant (R) and -susceptible (S) insects have been reported in the past. However, the studies focused mostly on herbivorous pests, rather than predacious species, such as ladybird beetles. Using R and S Propylaea japonica (thunberg), a full-length cDNA sequence (2928 bp) of the ace1-type AChE gene was determined for the first time. The ace1 encoding a protein of 645 amino acids contained typical conserved motifs, such as FGESAG domains, catalytic triad, acyl pocket, oxyanino hole, choline binding site, peripheral anionic site, omega loop and conserved aromatic residues. R P. japonica displayed 50-times greater resistance to chlorpyrifos or mathamidophos with a significantly lower AChE sensitivity to paraoxon, malaoxon, chlorpyrifos or methamidophos than its S counterpart. Five amino acids in the ace1 of R P. japonica differed from those found in S P. japonica. One of them, F358S, located in the acyl-binding pocket, might play a crucial role in the resistance of the insect to organophosphates (OPs). Whereas, K493E and I538V, which were close to some of the conserved aromatic amino acids (i.e., H509, Y511, and W499) in the gorge, and G571R and T576A near C593 that formed the disulfide bonds with C471, might also involve in the change of insecticide resistance in P. japonica. AChE insensitivity and amino acid replacements, particularly F358S, might be the determining factors in the alteration of OPs-resistance in P. japonica.
The status of snow leopards Panthera uncia, and high altitude use by common leopards P. pardus, in north-west Yunnan, China
Authors: Buzzard Paul J. , Li Xueyou , Bleisch William V. 
Published: July 2017

AbstractThe Endangered snow leopard Panthera uncia is a flagship species of mountainous Asia and a conservation priority. China is the most important country for the species’ conservation because it has the most potential habitat and the largest population of snow leopards. North-west Yunnan province in south-west China is at the edge of the snow leopard's range, and a biodiversity hotspot, where three major Asian rivers, the Yangtze, Mekong and Salween, flow off the Tibetan plateau and cut deep valleys through the Hengduan Mountains. The snow leopard's status in north-west Yunnan is uncertain. We conducted interviews and camera-trapping surveys to assess the species’ status at multiple sites: two east of the Yangtze River and two between the Yangtze and Mekong Rivers. Thirty-eight herders/nature reserve officials interviewed claimed that snow leopards were present, but in 6,300 camera-trap days we did not obtain any photographs of snow leopards, so if the species is present, it is rare. However, we obtained many photographs of potential prey, such as blue sheep Pseudois nayaur, as well as photographs of common leopards Panthera pardus, at high elevations (3,000–4,500 m). More study is necessary in Yunnan and other areas of south-west China to investigate the status and resource overlap of snow leopards and common leopards, especially as climate change is resulting in increases in common leopard habitat and decreases in snow leopard habitat.

Aim
The study purpose was to provide evidence of validity for the Primary Health Care Engagement (PHCE) Scale, based on exploratory factor analysis and reliability findings from a large national survey of regulated nurses residing and working in rural and remote Canadian communities.

Background
There are currently no published provider-level instruments to adequately assess delivery of community-based primary health care, relevant to ongoing primary health care (PHC) reform strategies across Canada and elsewhere. The PHCE Scale reflects a contemporary approach that emphasizes community-oriented and community-based elements of PHC delivery.

Methods
Data from the pan-Canadian Nursing Practice in Rural and Remote Canada II (RRNII) survey were used to conduct an exploratory factor analysis and evaluate the internal consistency reliability of the final PHCE Scale.

Findings
The RRNII survey sample included 1587 registered nurses, nurse practitioners, licensed practical nurses, and registered psychiatric nurses residing and working in rural and remote Canada. Exploratory factor analysis identified an eight-factor structure across 28 items overall, and good internal consistency reliability was indicated by an α estimate of 0.89 for the final scale. The final 28-item PHCE Scale includes three of four elements in a contemporary approach to PHC (accessibility/availability, community participation, and intersectoral team) and most community-oriented/based elements of PHC (interdisciplinary collaboration, person-centred, continuity, population orientation, and quality improvement). We recommend additional psychometric testing in a range of health care providers and settings, as the PHCE Scale shows promise as a tool for health care planners and researchers to test interventions and track progress in primary health care reform.
