Authors: Gdanetz Lorraine M. , Hamer Mika K. , Thomas Eileen , Tarasenko Lindsey M. , Horton-Deutsch Sara , Jones Jacqueline 
Published: April 2018

Background:
A main concern that remains with the continued growth of online nursing education programs is the way educator and student relationships can be affected by new technologies. This interpretive study aims to gain an understanding of how technology influences the development of interpersonal relationships between the student and faculty in a virtual learning environment.

Method:
Using an established structured approach to qualitative metasynthesis, a search was conducted using PubMed, EBSCO, CINAHL, Medline, ProQuest, Ovid Nursing databases, and Google Scholar, focused on caring and relational aspects of online nursing education.

Results:
Technology alters communication, thereby positioning the intentionality of the educator at the heart of interpersonal relationship development in virtual learning spaces.

Conclusion:

This interpretive synthesis of prior qualitative research supports the development of a framework for online nursing courses, the need for continuing education of nursing faculty, the value of caring intentions, and enhancement of the educator's technological proficiency. [

Diagnostic Reasoning and Cognitive Biases of Nurse Practitioners
Authors: Lawson Thomas N. 
Published: April 2018

Background:
Diagnostic reasoning is often used colloquially to describe the process by which nurse practitioners and physicians come to the correct diagnosis, but a rich definition and description of this process has been lacking in the nursing literature.

Method:
A literature review was conducted with theoretical sampling seeking conceptual insight into diagnostic reasoning.

Results:
Four common themes emerged: Cognitive Biases and Debiasing Strategies, the Dual Process Theory, Diagnostic Error, and Patient Harm. Relevant cognitive biases are discussed, followed by debiasing strategies and application of the dual process theory to reduce diagnostic error and harm.

Conclusion:

The accuracy of diagnostic reasoning of nurse practitioners may be improved by incorporating these items into nurse practitioner education and practice. [

Learning About Conflict and Conflict Management Through Drama in Nursing Education
Authors: Arveklev Susanna H. , Berg Linda , Wigert Helena , Morrison-Helme Morag , Lepp Margret 
Published: April 2018

Background:
In the health care settings in which nurses work, involvement in some form of conflict is inevitable. The ability to manage conflicts is therefore necessary for nursing students to learn during their education.

Method:
A qualitative analysis of 43 written group assignments was undertaken using a content analysis approach.

Results:
Three main categories emerged in the analysis—to approach and integrate with the theoretical content, to step back and get an overview, and to concretize and practice—together with the overall theme, to learn by oscillating between closeness and distance.

Conclusion:

Learning about conflict and conflict management through drama enables nursing students to form new knowledge by oscillating between closeness and distance, to engage in both the fictional world and the real world at the same time. This helps students to form a personal understanding of theoretical concepts and a readiness about how to manage future conflicts. [

Standardized Patient Simulation to Facilitate Learning in Evidence-Based Oncology Symptom Management
Authors: Ross Jennifer Gunberg , Burrell Sherry A. 
Published: April 2018

Background:
New graduate nurses lack the specialty knowledge and skills necessary to provide effective symptom management to oncology patients. The purpose of this article is to describe the development of a simulation-based learning experience using standardized patients to enhance undergraduate nursing students' ability to apply evidence-based principles learned in the classroom to oncology symptom management practice.

Method:
Faculty developed two standardized patient simulations for a 7-week senior seminar in evidence-based oncology symptom management.

Results:
Faculty, students, and standardized patients provided positive feedback. Students appreciated the realism and innovation of using simulation in a seminar-style course. Faculty and students identified that more time was needed for the simulations, and revisions are planned for the next offering of the seminar to address this concern.

Conclusion:

The integration of standardized patients is a feasible learning strategy to facilitate learning of evidence-based oncology symptom management principles among undergraduate nursing students. [

Published: April 2018

AbstractOmmatissus lybicusde Bergevin (Hemiptera: Tropiduchidae) is a key pest of date palm (Phoenix dactyliferaLinnaeus; Arecaceae) with worldwide distribution and various management strategies. To study genetic diversity of date palm hopper, a series of experiments was conducted on genetic structure and genetic diversity of 15 geographic populations ofO.lybicus(Abu Musa, Bam, Bushehr, Behbahan, Tezerj, Fin, Jiroft, Shahdad, Jahrom, Ghire Karzin, Ghasre Shirin, Iran; Pakistan; Oman; Egypt; and Tunisia) by amplified fragment length polymorphism, cytochromecoxidase subunit I (COI), and 28S rRNA markers. Analysis of molecular variance analysis of amplified fragment length polymorphism data and COI sequences revealed a significant variation amongO.lybicuspopulations (94.12% and 65.08% similarities for amplified fragment length polymorphism and COI, respectively). The 28S rDNA sequences from different populations were identical. Phylogenetic network inferred from amplified fragment length polymorphism data and COI sequences grouped two geographically close populations (Tezerj and Bam) in the two distinct clades while far apart geographical populations bunched in the same or close clades. These two populations experience repeated exposure to heavy pesticide applications annually. In conclusion, study of the genetic structure revealed a considerable variation betweenO.lybicuspopulations under intensive chemical strategies.
Distribution of non-myelinating Schwann cells and their associations with leukocytes in mouse spleen revealed by immunofluorescence staining

Published: April 2018

The nervous system and the immune system communicate extensively with each other in order to maintain homeostasis and to regulate the immune response. The peripheral nervous system (PNS) communicates specifically with the immune system according to local interactions, including the “hardwiring” of sympathetic/parasympathetic (efferent) and sensory nerves (afferent) to lymphoid tissue and organs. To reveal this type of bidirectional neuroimmune interaction at the microscopic level, we used immunofluorescent staining of glial fibrillary acidic protein (GFAP) coupled with confocal microscopy/3D reconstruction to reveal the distribution of non-myelinating Schwann cells (NMSCs) and their interactions with immune cells inside mouse spleen. Our results demonstrate i) the presence of an extensive network of NMSC processes in all splenic compartments including the splenic nodules, periarteriolar lymphoid sheath (PALS), marginal zone, trabecula, and red pulp; ii) the close association of NMSC processes with blood vessels (including central artries and their branches, marginal sinuses, penicillar arterioles and splenic sinuses); iii) the close “synapse-like” interaction/association of NMSC processes with various subsets of dendritic cells (DCs; e.g., CD4+CD11c+ DCs, B220+CD11c+ DCs, and F4/80+ CD11c+ DCs), macrophages (F4/80+), and lymphocytes (B cells, CD4+ T helper cells). Our novel findings concerning the distribution of NMSCs and NMSC-leukocytes interactions inside mouse spleen should improve our understanding of the mechanisms through which the PNS affects cellular- and humoral-mediated immune responses in a variety of health conditions and infectious/non-infectious diseases.

Published: April 2018

Abstract. This work presents new results about sporadic E-layers (Es layers) using
GPS (global positioning system) radio occultation (RO) measurements obtained
from the FORMOSAT-3/COSMIC satellites and digisonde data. The RO profiles are
used to study the Es layer occurrence as well as its intensity of the
signal-to-noise ratio (SNR) of the 50 Hz GPS L1 signal. The methodology was
applied to identify the Es layer on RO measurements over Cachoeira Paulista, a
low-latitude station in the Brazilian region, in which the Es layer
development is not driven tidal winds only as it is at middle latitudes. The
coincident events were analyzed using the RO technique and ionosonde observations during the
year 2014 to 2016. We used the electron density obtained using
the blanketing frequency parameter (fbEs) and the Es layer height
(h'Es) acquired from the ionograms to validate the satellite measurements.
The comparative results show that the Es layer characteristics extracted
from the RO measurements are in good agreement with the Es layer parameters
from the digisonde. Keywords. Ionosphere (ionosphere–atmosphere interactions)
A case study of developmental palaeontology in &lt;i&gt;Stereosternum tumidum&lt;/i&gt; (Mesosauridae, Parareptilia)
Authors: Bickelmann Constanze , Tsuji Linda A. 
Published: April 2018

Abstract. Ontogenetic series of extinct taxa are rare. However, if preserved, fossil
embryos and juveniles can provide evidence of developmental plasticity as
related to ecological specialization. Here, we describe articulated and
isolated juvenile material found in close association with an adult
mesosaurid Stereosternum tumidum (MB.R.2089) from Lower Permian
sediments in Brazil, housed in the collection of the Museum für
Naturkunde Berlin. Stylopodial, zeugopodial, and autopodial elements are not
yet completely ossified in the juveniles, as indicated by compression
artifacts on the surface of the bone. These correspond to internal
ossification processes, which have been demonstrated in other aquatic taxa.
Quantitative analysis of measurements in juvenile and adult material reveals
differing growth rates between limb elements: hind limb zeugopodia, which are
massive and elongate in the adult as needed for propulsion, are already
comparatively larger in the juvenile than the humeri, femora, and also the
zeugopodia of the forelimb. This pattern differs from that seen in another
extinct aquatic reptile, Hovasaurus boulei. Nevertheless, we
attribute the accelerated growth rate or earlier onset of ossification to be
a potential developmental pathway generating limb element variation in the
adult present in 280 million year old mesosaurs, which are known for their
fully aquatic lifestyle, in which the hind limbs play a more prominent role
than the forelimbs.
Benefits of subcomponent over full-scale blade testing elaborated on a trailing-edge bond line design validation
Authors: Rosemeier Malo , Basters Gregor , Antoniou Alexandros 
Published: April 2018

Abstract. Wind turbine rotor blades are designed and certified according to the current
IEC (2012) (International Electrotechnical Commission) and DNV GL AS (2015)
(Det Norske Veritas Germanischer Lloyd Aksjeselskap) standards, which include
the final full-scale experiment. The experiment is used to validate the
assumptions made in the design models. In this work the drawbacks of
traditional static and fatigue full-scale testing are elaborated, i.e., the
replication of realistic loading and structural response. Subcomponent
testing is proposed as a potential method to mitigate some of the drawbacks.
Compared to the actual loading that a rotor blade is subjected to under field
conditions, the full-scale test loading is subjected to the following
simplifications and constraints: first, the full-scale fatigue test is
conducted as a cyclic test, wherein the load time series obtained from
aeroservoelastic simulations are simplified to a damage-equivalent load
range. Second, the load directions are typically applied solely in two
directions, often pure lead–lag and flapwise directions which are not
necessarily the most critical load directions for a particular blade segment.
Third, parts of the blade are overloaded by up to 20 % to achieve
the target load along the whole span. Fourth, parts of the blade are not
tested due to load introduction via load frames. Finally, another downside of
a state-of-the-art, uni-axial, resonant, full-scale testing method is that
dynamic testing at the eigenfrequencies of today's blades with respect to the
first flapwise mode between 0.4 and 1.0 Hz results in
long test times. Testing usually takes several months. In contrast, the
subcomponent fatigue testing time can be substantially shorter than the
full-scale blade test since (a) the load can be introduced with higher
frequencies which are not constrained by the blade's eigenfrequency, and (b) the
stress ratio between the minimum and the maximum stress exposure to which
the structure is subjected can be increased to more realistic values.
Furthermore, subcomponent testing could increase the structural reliability
by focusing on the critical areas and replicating the design loads more
accurately in the most critical directions. In this work, the comparison of
the two testing methods is elaborated by way of example on a trailing-edge
bond line design.

Verkeer als stelsel met stelselverantwoordelijkheid voor veiligheid?

Reduction of traffic unsafety from a systems point of view: a role for co-responsibility?
Lack of safety leading to death or injury has many aspects: personal violence, traffic, accidents at home or the work place, not to mention other external sources as radiation and fine dust or internal sources like diseases. In this paper we restrict ourselves to the lack of safety in traffic as a system, and address the following questions: (1) Is traffic a system with one dominant responsible actor (Ministry of Traffic)? (2) What explanations are offered for the lack of safety? (3) Who is responsible for safety? (4) What sort of interventions are suitable for enhancing safety? and (5) What type of process/consultancy is most appropriate for answer the preceding questions?The paper arrives at its conclusions via an indirect way, namely a short analysis of what a system comprises and what constitutes an explanation, responsibility and effectiveness. It appears that we are all causally involved in the lack of safety, and we are all responsible at all levels of society: micro-individual, meso-organizational and macro-societal. Therefore a promising route to maximize safety is a governance perspective comprising multiple stakeholder co-responsibility. It remains to be seen whether this perspective should replace the predominant command and control governance or complement it.

Managing incidents in education
Incidents in organizations are inevitable. Sometimes these incidents get out of hand and reach the newspapers. But there are also incidents that are addressed in a timely and effective manner and do not escalate to become serious failures. Based on six concrete ‘near misses’ within the education sector, we have investigated how appropriate actions can prevent serious omissions and which mechanisms play a role in this.

Over frauderende slachtoffers en WAM-verzekeraars. En de vraag of civielrechtelijke sanctionering mogelijk, of zelfs gewenst is
Bij fraude door hun verzekerden kunnen verzekeraars ontkomen aan hun dekkingsplicht. Kan dat ook in de verhouding tussen WAM-verzekeraars en verkeersslachtoffers die ageren op grond van artikel 6 WAM? De kantonrechter te Amsterdam zag geen grond voor (analoge) toepassing van artikel 7:941 lid 5 BW of voor verval van het recht op uitkering via de band van de redelijkheid en billijkheid. Naar aanleiding van het kantonvonnis bespreken de auteurs in deze bijdrage of het verval van het recht op uitkering het door verzekeraars gewenste effect sorteert en of fraude in de aansprakelijkheidsverhouding kan derogeren aan het recht op schadevergoeding.

Published: April 2018

O objetivo desse estudo foi avaliar a qualidade do solo sob povoamentos florestais homogêneos (Acacia mangium - acácia, Mimosa artemisiana - mimosa e Eucalyptus grandis x Eucalyptus urophylla - eucalipto) em comparação com área de pastagem de Brachiaria sp. (pasto) e floresta secundária. O trabalho foi conduzido na Fazenda Cachoeirão, em Além Paraíba - MG. A amostragem foi realizada nas camadas de 0,00 - 0,05 m e 0,05 - 0,10 m. Foram analisados os atributos químicos tais como teor de nutrientes, pH, acidez potencial (H + Al) e teor de carbono orgânico (COT), e os atributos físicos densidade do solo (Ds), volume total de poros (VTP) e a estabilidade de agregados. Os valores de saturação por bases foram muito baixos em todas as áreas. Dentre os povoamentos florestais, as áreas de mimosa e eucalipto proporcionaram maior adição de COT ao solo. Não houve diferença significativa para as variáveis Ds e VTP em nenhuma das camadas analisadas. O atributo químico que possibilitou melhor diferenciação entre as áreas foi o teor de carbono orgânico (COT). As florestas de mimosa e acácia foram as que mais contribuíram para a estabilização dos agregados do solo na camada de 0,00 - 0,05 m. Esta camada foi a que apresentou melhor diferenciação entre as áreas em relação à estabilidade de agregados. A área de pastagem foi a que mais se assemelhou à floresta secundária quanto à estabilidade de agregados nas camadas de 0,00 - 0,05 m e 0,05 - 0,10 m. Para a profundidade de 0,05 - 0,10 m, não foram verificadas diferenças estatísticas entre as áreas para as variáveis físicas estudadas.
The effect of pointing on spatial working memory in a 3D virtual environment
Authors: Liu Xiaoxing , Thomas Geb W. , Cook Susan W. 
Published: April 2018

SummaryPointing to locations can either help or hinder people's ability to recall spatial information. Prior research has focused on two‐dimensional spatial memory and pointing in real world tasks. The effect of pointing on three‐dimensional spatial memory in virtual environments remains unexplored. We examine this effect by comparing participants' recall when they point to and memorize a series of three‐dimensional locations using a gesture interface, and when they only passively view and memorize the spatial array. Thirty‐three participants completed 50 trials in both conditions. The results reveal that pointing has a negative effect on memory in the three‐dimensional virtual environment. These findings held across memory in the x–y plane of the computer screen as well as memory in the virtual third dimension. When they pointed during encoding, participants also responded more slowly, suggesting a higher cognitive load. Thus, active pointing may cause interference when users are simultaneously performing spatial memorization tasks.
Long‐Range Nonvolatile Electric Field Effect in Epitaxial Fe/Pb(Mg1/3Nb2/3)0.7Ti0.3O3 Heterostructures

Published: April 2018

AbstractOne of the ideal candidates of using electric field to manipulate magnetism is the recently developed multiferroics with emergent coupling of magnetism and electricity, particularly in synthesizing artificial nanoscale ferroelectric and ferromagnetic materials. Here, a long‐range nonvolatile electric field effect is investigated in Fe/Pb(Mg1/3Nb2/3)0.7Ti0.3O3 heterostructure using the dependence of the magnon‐driven magnetoelectric coupling on the epitaxial Fe thin film (4–30 nm) thickness at room temperature using measurements based on the ferromagnetic resonance. The magnon‐driven magnetoelectric coupling tuning of the ferromagnetic resonance field shows a linear response to the electric field, with a resonance field shift that occurs under both positive and negative remanent polarizations, and demonstrates nonvolatile behavior. Moreover, the spin diffusion length of the epitaxial Fe thin film of ≈9 nm is obtained from the results that the change of the cubic magnetocrystalline anisotropy field under different electric fields varies with Fe thickness. These results are promising for the design of future multiferroic devices.
