Personality As Correlates Of Paternal Postnatal Depression
Authors: Shintya Lea Andy 
Published: March 2020

During pregnancy and birth, for mother and newborn baby are the focuses of attention. Many times fathers are left out. This study aimed to determine if personality correlates to paternal postnatal depression. The study used descriptive correlational design, where in data from 177 respondents gathered through purposive sampling. Personality in term of extraversion and neuroticism were significantly related to paternal postnatal depression. Neuroticism was positively correlated to paternal postnatal depression but agreeableness, conscientiousness, openness were not significantly correlated to paternal postnatal depression. This implies that those fathers who scored high in extraversion have low tendency to experience paternal postnatal depression. However, the higher the score in neuroticism the higher in the tendency to experience paternal postnatal depression. From result of this study, researcher have recommendations for nurse educator should emphasize to the future nurse and to the professional nurse that fathers experiences postnatal depression like mothers. When giving health teaching both in the community and in the hospital, nurse educator should consider discussing the topic of postnatal depression. They too should encourage the husbands or fathers to attend the health education activity. Another study can be done comparing the postnatal depression experience by the wife and husband.

Two-component Jets of GRB 160623A as Shocked Jet Cocoon Afterglow
Authors: Chen Wei Ju , Urata Yuji , Huang Kuiyun , Takahashi Satoko , Petitpas Glen , Asada Keiichi 
Published: March 2020

Abstract
Two components of jets associated with the afterglow of the gamma-ray burst (GRB) 160623A were observed with multifrequency observations including long-term monitoring in a submillimeter range (230 GHz) using the Submillimeter Array. The observed light curves with temporal breaks suggest on the basis of the standard forward-shock synchrotron-radiation model that the X-ray radiation is narrowly collimated with an opening angle

, whereas the radio radiation originated from wider jets (∼27°). The temporal and spectral evolutions of the radio afterglow agree with those expected from a synchrotron-radiation modeling with typical physical parameters, except for the fact that the observed wide jet opening angle for the radio emission is significantly larger than the theoretical maximum opening angle. By contrast, the opening angle of the X-ray afterglow is consistent with the typical value of GRB jets. Since the theory of the relativistic cocoon afterglow emission is similar to that of a regular afterglow with an opening angle of ∼30°, the observed radio emission can be interpreted as the shocked jet cocoon emission. This result therefore indicates that the two components of the jets observed in the GRB 160623A afterglow are caused by the jet and the shocked jet cocoon afterglows.

Authors: Lee Daphne S.K. , Abdullah Khatijah Lim , Chinna Karuthan , Subramanian Pathmawathi , Bachmann Robert Thomas 
Published: March 2020

Background:
Previous studies of nurses' critical thinking skills that included demographic characteristics as determinants have been inconclusive. This study explored demographic determinants of critical thinking skills among nurses from public hospitals in Peninsular Malaysia.

Method:
This cross-sectional study included 549 nurses recruited via multistage cluster sampling. Nurses completed the demographic questionnaire and Health Sciences Reasoning Test (HSRT).

Results:

The majority of respondents failed to demonstrate critical thinking skills with a mean overall HSRT score of 13.8 (
SD
= 3.4). Educational qualifications (
p
= .003) and clinical specialties (
p
= .022) were significantly related to nurses' critical thinking skills. Years of clinical experience, age, and job ranking were not significant

Conclusion:

The findings indicate a need to address the present curriculum in nursing education and to reinforce critical thinking skills in the nursing workforce. Future research on how nurses in Malaysia acquire critical thinking skills is needed.

Walking a Fine Line: Graduate Nurses' Transition Experiences During Orientation
Authors: Delaney Colleen 
Published: March 2020

ABSTRACT
A phenomenological study was conducted to investigate graduate nurses' transition experiences during orientation. A purposive sample of 10 graduate nurses participated. Ten theme clusters emerged when the formulated meanings were organized into categories. Graduates experienced mixed emotions as they began orientation. Preceptors played a key role in the transition process, affecting participants' thoughts and progress. Graduates quickly realized the many differences between work and school, and were surrounded by feelings of stress as they assumed the new role of RN. For some, coping with death and dying was an emotionally difficult experience for which they felt unprepared. Finding a rhythm brought graduates confidence and feelings of accomplishment, and self-reflection emerged as an important and integral part of the transition process. Despite the challenges and stress of orientation, graduates found great meaning in their work, and most expressed readiness to be on their own by the end of 12 weeks.

Published: March 2020

ABSTRACT
The goal of the present study was to determine whether dietary supply of ω-3 essential fatty acid (EFA) influences visual development in healthy pre-term and full-term infants. Visual status was examined in human milk-fed infants (ample dietary ω-3 EFA supply) and corn oil-based formula-fed infants (no dietary ω-3 EFA; standard formula prior to 1987). At 57 weeks postconception (4 months adjusted age), both pre-term and full-term human milk-fed infants had significantly better visual evoked potential (VEP) and forced-choice preferentiallooking (FPL) acuity than formula-fed infants. Acuity was correlated with a dietary ω-3 sufficiency index from red blood cell membranes obtained at 57 weeks postconception. At 36 months, full-term human milk-fed children had significantly better random dot stereo acuity and letter matching ability than formula-fed children. Stereo acuity and performance on the letter matching test were correlated with a dietary ω-3 sufficiency index from red blood cell membranes obtained at 4 months. These results suggest that dietary ω-3 fatty acids play an important role in visual development.
Karst‐induced sinkhole detection using an integrated geophysical survey: a case study along the Riyadh Metro Line 3 (Saudi Arabia)

Published: March 2020

ABSTRACTNowadays, most planned large infrastructure projects increasingly use multi‐technique geophysical methods integrated with geotechnical surveys to assess detection and exploration of karst‐related systems. This article focuses on the case of a large sinkhole found during the geophysical surveys that were carried out along Riyadh’s new Metro Line 3 (Saudi Arabia). This line is the longest (41 km) of the six that are currently under construction in the framework of the largest public rail infrastructure project, the Riyadh Metro Project (176 km).A multi‐technique geophysical survey combining seismic (1040 m of seismic refraction tomography and four downhole tests), electrical (1035 m of electrical resistivity tomography), and electromagnetic methods (1040 m of ground penetration radar) was conducted to shed light on the subsurface geology along the section of this case study. The combination of the geophysical methods led to early identification of a subsurface area of lower resistivity and seismic velocity than the background values of the carbonate bedrock. It also revealed smaller fractures that could lead to future sinkhole formation. A subsequent dense investigatory borehole grid (14 boreholes, five probeholes, 38 standard penetration tests, nine TV‐logging, and five pressuremeter tests) further confirmed the presence of a buried sinkhole.This paper shows the results of each individual geophysical method as well as the final geotechnical interpretation based on the combination of geophysical methods with borehole drilling. It concludes that the use of a single method for karst assessment, whether a geophysical method or borehole drilling, does not allow a sufficiently detailed geotechnical profile of the ground. This case study provides basic guidance on the most suitable and accurate techniques to detect similar karstic features across Riyadh.
Geophysical pre‐investigation for a Stockholm tunnel project: joint inversion and interpretation of geoelectric and seismic refraction data in an urban environment
Authors: Ronczka Mathias , Wisén Roger , Dahlin Tbrleif 
Published: March 2020

ABSTRACTUnderground constructions for public traffic purposes are becoming increasingly important for urban areas in order to use the limited space more efficiently. Several electric resistivity tomography and seismic refraction tomography measurements were performed crossing a water passage near Stockholm during the pre‐investigation phase of a tunnel building project. The objective was to determine the bedrock interface and qualitatively assess the rock quality. The scope of this study is to present a field case in an urban environment and show improvements of geophysical results due to additional model constraints by a joint inversion. Results of individual inversions show a large transition zone below the seabed from electric resistivity tomography. Some parts of the seismic refraction tomography have a low model resolution, due to gas‐bearing sediments with a low velocity together with a high noise level, which leads to insufficient investigation depth that makes it difficult to determine the bedrock interface. However, the bedrock interface could be reconstructed in the resistivity model by performing a joint inversion, using the seismic velocity model to constrain the electric resistivity tomography model and vice versa. Adjacent geotechnical soundings support the joint inversion results. A vertical low resistive zone could be identified as a dominant fracture zone in the southern part of the investigated area. In general, the joint inversion approach significantly improved the electric resistivity tomography results and provided a more reliable bedrock estimation.
Shear‐wave velocity structure from MASW and SPAC methods: The case of Adra town, SE Spain

Published: March 2020

ABSTRACTThe damage distribution in the town of Adra (south‐eastern Spain) during the 1993 and 1994 Adra earthquakes of magnitude Mw~5.0 and maximum intensity degree of VII (European Macroseismic Scale) was mainly concentrated in the southeast sector, where the low‐diagenetic (soft) sediments outcrop. As new urbanizations are being planned in this sector, a soil classification based on the shallow shear‐wave velocity () structure is needed. For the purpose of earthquake disaster mitigation, the Spatial Autocorrelation (SPAC) and the Multichannel Analysis of Surface Waves (MASW) methods were used to propose integrated 2D models for the seismic response characterization of the shallow geology. Joint inversion of H/V spectral ratios of ambient noise, interpreted under the Diffuse Field Approach and the dispersion curves derived from the SPAC method allowed us to obtain more constrained models. Both SPAC and MASW methods provided similar results for the surveyed geological formations. From these models, a classification of the geological formations was carried out in terms of values and Eurocode 8 (European Committee for Standardization ) classes. Lower values in the 180‐360 m/s range were found in the southeastern sector of the town, where soft sediments outcrop and some building damage was reported during the 1993‐1994 earthquakes. The highest values exceeding 800 m/s appear in the northern sector, where the hardest rocks outcrop and no building damage was reported. The combination of the well‐suited database prepared for different geological formations with the 1:5,000 scale geological mapping was an important step to obtain the detailed soil microzonation map of Adra. This approach offered a new predictive insight into the building damage distribution, which would contribute to the appropriate urban planning for the future growth of the town.

Abstract
Dendritic cells (DCs) participate in the pathogenesis of several diseases. We investigated DCs and the connection between mucosa and joints in a murine model of Yersinia enterocolitica O:3–induced reactive arthritis (ReA) in TNFRp55−/− mice. DCs of mesenteric lymph nodes (MLN) and joint regional lymph nodes (RLN) were analyzed in TNFRp55−/− and wild-type mice. On day 14 after Y. enterocolitica infection (arthritis onset), we found that under TNFRp55 deficiency, migratory (MHChighCD11c+) DCs increased significantly in RLN. Within these RLN, resident (MHCintCD11c+) DCs increased on days 14 and 21. Similar changes in both migratory and resident DCs were also detected on day 14 in MLN of TNFRp55−/− mice. In vitro, LPS-stimulated migratory TNFRp55−/− DCs of MLN increased IL-12/23p40 compared with wild-type mice. In addition, TNFRp55−/− bone marrow–derived DCs in a TNFRp55−/− MLN microenvironment exhibited higher expression of CCR7 after Y. enterocolitica infection. The major intestinal DC subsets (CD103+CD11b−, CD103−CD11b+, and CD103+CD11b+) were found in the RLN of Y. enterocolitica–infected TNFRp55−/− mice. Fingolimod (FTY720) treatment of Y. enterocolitica–infected mice reduced the CD11b− subset of migratory DCs in RLN of TNFRp55−/− mice and significantly suppressed the severity of ReA in these mice. This result was associated with decreased articular IL-12/23p40 and IFN-γ levels. In vitro FTY720 treatment downregulated CCR7 on Y. enterocolitica–infected bone marrow–derived DCs and purified MLN DCs, which may explain the mechanism underlying the impairment of DCs in RLN induced by FTY720. Taken together, data indicate the migration of intestinal DCs to RLN and the contribution of these cells in the immunopathogenesis of ReA, which may provide evidence for controlling this disease.

Abstract
T cell epitopes are mostly nonmodified peptides, although posttranslationally modified peptide epitopes have been described, but they originated from viral or self-proteins. In this study, we provide evidence of a bacterial methylated T cell peptide epitope. The mycobacterial heparin-binding hemagglutinin (HBHA) is a protein Ag with a complex C-terminal methylation pattern and is recognized by T cells from humans latently infected with Mycobacterium tuberculosis. By comparing native HBHA with recombinant HBHA produced in Mycobacterium smegmatis (rHBHA-Ms), we could link antigenic differences to differences in the methylation profile. Peptide scan analyses led to the discovery of a peptide containing methyl lysines recognized by a mAb that binds to native HBHA ∼100-fold better than to rHBHA-Ms. This peptide was also recognized by T cells from latently infected humans, as evidenced by IFN-γ release upon peptide stimulation. The nonmethylated peptide did not induce IFN-γ, arguing that the methyl lysines are part of the T cell epitope.
On the relation between avalanche occurrence and avalanche danger level
Authors: Schweizer Jürg , Mitterer Christoph , Techel Frank , Stoffel Andreas , Reuter Benjamin 
Published: March 2020

Abstract. In many countries with seasonally snow-covered mountain
ranges warnings are issued to alert the public about imminent avalanche
danger, mostly employing an ordinal, five-level danger scale. However, as
avalanche danger cannot be measured, the characterization of avalanche
danger remains qualitative. The probability of avalanche occurrence in
combination with the expected avalanche type and size decide on the degree
of danger in a given forecast region (≳100 km2). To describe
avalanche occurrence probability, the snowpack stability and its spatial
distribution need to be assessed. To quantify the relation between avalanche
occurrence and avalanche danger level, we analyzed a large data set of
visually observed avalanches (13 918 in total) from the region of Davos
(eastern Swiss Alps, ∼300 km2), all with mapped
outlines, and we compared the avalanche activity to the forecast danger level
on the day of occurrence (3533 danger ratings). The number of avalanches per
day strongly increased with increasing danger level, confirming that not only
the release probability but also the frequency of locations with a weakness
in the snowpack where avalanches may initiate from increase within a
region. Avalanche size did not generally increase with increasing avalanche
danger level, suggesting that avalanche size may be of secondary importance
compared to snowpack stability and its distribution when assessing the
danger level. Moreover, the frequency of wet-snow avalanches was found to be
higher than the frequency of dry-snow avalanches for a given day and danger
level; also, wet-snow avalanches tended to be larger. This finding may
indicate that the danger scale is not used consistently with regard to
avalanche type. Even though observed avalanche occurrence and avalanche danger
level are subject to uncertainties, our findings on the characteristics of
avalanche activity suggest reworking the definitions of the European
avalanche danger scale. The description of the danger levels can be
improved, in particular by quantifying some of the many proportional
quantifiers. For instance, based on our analyses, “many avalanches”, expected
at danger level 4-High, means on the order of at least 10 avalanches per
100 km2. Whereas our data set is one of the most comprehensive,
visually observed avalanche records are known to be inherently incomplete so
that our results often refer to a lower limit and should be confirmed using
other similarly comprehensive data sets.
Variability scaling and consistency in airborne and satellite altimetry measurements of Arctic sea ice
Authors: Xu Shiming , Zhou Lu , Wang Bin 
Published: March 2020

Abstract. Satellite and airborne remote sensing provide complementary capabilities for the observation of the sea ice cover.
However, due to the differences in footprint sizes and noise levels of the measurement techniques, as well as sea ice's variability across scales, it is challenging to carry out inter-comparison or consistently study these observations.
In this study we focus on the remote sensing of sea ice thickness parameters and carry out the following: (1) the analysis of variability and its statistical scaling for typical parameters and (2) the consistency study between airborne and satellite measurements.
By using collocating data between Operation IceBridge and CryoSat-2 (CS-2) in the Arctic, we show that consistency exists between the variability in radar freeboard estimations, although CryoSat-2 has higher noise levels.
Specifically, we notice that the noise levels vary among different CryoSat-2 products, and for the European Space Agency (ESA) CryoSat-2 freeboard product the noise levels are at about 14 and 20 cm for first-year ice (FYI) and multi-year ice (MYI), respectively.
On the other hand, for Operation IceBridge and NASA's Ice, Cloud, and land Elevation Satellite (ICESat), it is shown that the variability in snow (or total) freeboard is quantitatively comparable despite more than a 5-year time difference between the two datasets.
Furthermore, by using Operation IceBridge data, we also find widespread negative covariance between ice freeboard and snow depth, which only manifests on small spatial scales (40 m for first-year ice and about 80 to 120 m for multi-year ice).
This statistical relationship highlights that the snow cover reduces the overall topography of the ice cover.
Besides this, there is prevalent positive covariability between snow depth and snow freeboard across a wide range of spatial scales.
The variability and consistency analysis calls for more process-oriented observations and modeling activities to elucidate key processes governing snow–ice interaction and sea ice variability on various spatial scales.
The statistical results can also be utilized in improving both radar and laser altimetry as well as the validation of sea ice and snow prognostic models.
Digital nomads, coworking, and other expressions of mobile work on Twitter

Published: March 2020

We analyze a set of Twitter hashtags to ascertain how contemporary parlance in social media can illuminate the rich cultural intersections between modern forms of work, use of technology, and physical mobility. We use network word co-occurrence analysis and topic modeling to reveal several thematic areas of discourse present in Twitter, each with its own affiliated terms and distinctive emphases. The first theme centers on worker identity and is currently dominated by the experiences of digital nomads. The second theme focuses on the practicalities of working in a physical location and is currently dominated by issues related to co-working spaces. Finally, the third theme is a loose and speculative set of ideas around the evolution of work in the future, predicting how enterprises may have to adapt to new ways of working. Our contribution is twofold. First, we contribute to scholarship on social media methods by showing how a robust analysis of Twitter data can help scholars find subthematic nuance within a complex discussion space by identifying the existence and boundaries of topical sub-themes. Second, we contribute to scholarship on the future of work by providing empirical evidence for the ways that the myriad terms related to mobility and work relate to one another and, most importantly, how these relations signal semantic centrality among those who share their thoughts on these types of work.
El difícil camino a la ordenación urbana del Área Metropolitana de San Salvador: una revisión crítica a los planes urbanos del AMSS 1953-1997
Authors: Chicas Molina Juan Carlos 
Published: March 2020

Se analizan tres de los principales planes urbanos elaborados para el Área Metropolitana de San Salvador (AMSS), identificando aquellos elementos componentes que configuraron la metrópolis salvadoreña. Se inicia con la propuesta de 1953, donde se propuso la estructuración de la ciudad por un sistema articulado de centros de barrio interconectado por un sistema vial moderno. Seguidamente, se examina METROPLAN 80 (1968), el cual abordó la estructuración de la ciudad desde una visión económica imperante en la época de fuerte planificación estatal. Finalmente, se revisa el plan PLAMADUR-AMSSA (1996), el cual propuso una redensificación del núcleo central de la ciudad, con miras a una ciudad compacta. Se concluye que el camino de gestión urbana del AMSS, ha seguido la dinámica al igual que la mayoría de las ciudades de la región, signada por las particularidades económicas, sociales y ambientales propias.
