Simulation Learning and Transfer in Undergraduate Nursing Education: A Grounded Theory Study
Authors: Miles David A. 
Published: June 2018

Background:
Experiential learning through simulation allows students to improve their cognitive, affective, and psychomotor skills. Yet, the process of how simulation learning transfers to clinical learning remains unanswered.

Method:
The classical grounded theory method was used to conceptualize the process by which simulation learning transfers to the clinical environment.

Results:
A model emerged that explained the simulation learning transfer process. The core category was Acting Like a Nurse and the model had 10 categories. The beginning stages of the model included the categories: Being in Simulation and Being in Clinical. The middle stages of the model reflected interaction between the student and the simulation experience, and included the categories Being Able to Practice, Getting Feedback, Making Sense of My Learning, Fitting Together, and Applying My Learning. The final stages of the model were Gaining Confidence and Becoming More Comfortable, with the outcome category Knowing What to Do.

Conclusion:

Simulation learning enhanced transfer of learning, specifically allowing students to take on the role behaviors of what will be expected of them as a practicing nurse. [

From Military to Academic Nursing: Embracing an Untapped Leadership Resource
Authors: Chargualaf Katie A. , Elliott Brenda , Patterson Barbara 
Published: June 2018

Background:
Strong leaders are essential for nursing program success, yet few faculty are interested or qualified to assume leadership positions within academia. This generates concern over lingering shortages and lack of succession planning.

Method:
A qualitative, descriptive study examined the transition experience of military nurses who became nurse educators. Emerging from an analysis of interviews with 13 Veteran nurses, the subtheme of “using my leadership toolbox” is explored within the context of leadership development.

Results:
Grounded in their military leadership development, the participants modeled essential leader qualities. They demonstrated confidence, vision, humility, a strong work ethic, clear communication, and a willingness to assume risk.

Conclusion:

Veteran nurses may be a viable solution to bring leadership knowledge, behaviors, and experience to the faculty role. Current academic leaders should facilitate the translation of these leadership attributes to address ongoing challenges facing nursing education. [

Authors: Minnich Margo , Kirkpatrick Amanda J. , Goodman Joely T. , Whittaker Ali , Stanton Chapple Helen , Schoening Anne M. , Khanna Maya M. 
Published: June 2018

Background:
Rubrics positively affect student academic performance; however, accuracy and consistency of the rubric and its use is imperative. The researchers in this study developed a standardized rubric for use across an undergraduate nursing curriculum, then evaluated the interrater reliability and general usability of the tool.

Method:
Faculty raters graded papers using the standardized rubric, submitted their independent scoring for interrater reliability analyses, then participated in a focus group discussion regarding rubric use experience.

Results:
Quantitative analysis of the data showed a high interrater reliability (α = .998). Content analysis of transcription revealed several positive themes: Consistency, Emphasis on Writing Ability, and Ability to Use the Rubric as a Teaching Tool. Areas for improvement included use of value words and difficulty with point allocation.

Conclusion:

Investigators recommend effective faculty orientation for rubric use and future work in developing a rubric to assess reflective writing. [

A Grounded Theory of the Resilience Process in Postqualification Nursing Students
Authors: Jackson Jennifer 
Published: June 2018

Background:
Resilience is important for undergraduate nursing students. However, little is known about resilience for postqualification nursing students who return for graduate studies. The purpose of this study was to explore the process of resilience for nursing students in graduate programs.

Method:
Postqualification nursing students were interviewed once to learn about their experiences in graduate education in this grounded theory study. Ten participants formed a convenience sample that was voluntarily recruited through a research course.

Results:
Participants described their process of resilience as one of managing challenges that was facilitated by passion and support. Participants applied several metacognitive and practical strategies. In addition, participants reported that they enjoyed or struggled through their studies (often both in varying degrees). The participants' resilience strategies reflected the application of prior learning.

Conclusion:

The process of resilience for postqualification students can be outlined in a theoretical process centered on managing challenges. Educators can support resilience by providing support and enabling resilience strategies. [

SIMULATING THE IMPACTS OF INDOOR VERTICAL FLOW CONSTRUCTED WETLANDS ON HVAC PERFORMANCE USING eQUEST AT HAMPSHIRE COLLEGE'S R. W. KERN CENTER
Authors: Raymond Matthew , Hews Sarah , Cianfrani Christina 
Published: June 2018

INTRODUCTION Hampshire College, in Amherst, Massachusetts, is taking part in the green building movement with the construction of the R. W. Kern Center, which opened in the spring of 2016. The building was certified to meet the Living Building Challenge in spring 2018 and has satisfied building standards such as Net Zero energy and water. To meet these standards, the design of the building employs solar photovoltaic panels, a rain water catchment and purification system, a greywater treatment system, storm water infiltration rain gardens, composting toilets, and control monitoring systems to make the building more efficient and decrease its harmful impacts on the environment. The greywater treatment system utilizes both indoor vertical flow constructed wetlands (VFCW) and an outdoor horizontal flow constructed wetland (HFCW) to filter greywater effluent from sinks and a coffee bar, meeting the requirement to treat and handle all wastewater generated on site. Although the VFCW system performance has been shown to be effective in exterior environments (Sklarz et al., 2009), its use inside a building requires scrutiny to verify that the adoption of this system does not affect the operation of essential building systems. The green systems that the Kern Center and others like it are employing may have impacts on the building's environment, construction and operation. These modifications must be monitored, and their effects quantified. The alteration of the thermal and air quality characteristics of the interior building has a significant effect on occupant health and the heating, ventilation and air conditioning (HVAC) energy on consumption. Several studies have investigated the benefits of indoor plants for air filtration or for exterior greywater filtration.
Identification of the First Teleost CD5 Molecule: Additional Evidence on Phenotypical and Functional Similarities between Fish IgM+ B Cells and Mammalian B1 Cells

Published: June 2018

AbstractDespite teleost fish being the first animal group in which all elements of adaptive immunity are present, the lack of follicular structures, as well as the fact that systemic Ab responses rely exclusively on unswitched low-affinity IgM responses, strongly suggests that fish B cell responses resemble mammalian B1 cell responses rather than those of B2 cells. In line with this hypothesis, in the current study, we have identified a homolog of CD5 in teleost fish. This pan-T marker belonging to the scavenger receptor cysteine-rich family of receptors is commonly used in mammals to distinguish a subset of B1 cells. Subsequently, we have demonstrated that a very high percentage of teleost IgM+ B cells express this marker, in contrast to the limited population of CD5-expressing B1 cells found in most mammals. Furthermore, we demonstrate that fish IgM+ B cells share classical phenotypic features of mammalian B1 cells such as large size, high complexity, high surface IgM, and low surface IgD expression, regardless of CD5 expression. Additionally, fish IgM+ B cells, unlike murine B2 cells, also displayed extended survival in cell culture and did not proliferate after BCR engagement. Altogether, our results demonstrate that although fish are evolutionarily the first group in which all the elements of acquired immunity are present, in the absence of follicular structures, most teleost IgM+ B cells have retained phenotypical and functional characteristics of mammalian B1 cells.

Abstract
Lysosomes maintain immune homeostasis through the degradation of phagocytosed apoptotic debris; however, the signaling events regulating lysosomal maturation remain undefined. In this study, we show that lysosome acidification, key to the maturation process, relies on mTOR complex 2 (mTORC2), activation of caspase-1, and cleavage of Rab39a. Mechanistically, the localization of cofilin to the phagosome recruits caspase-11, which results in the localized activation of caspase-1. Caspase-1 subsequently cleaves Rab39a on the phagosomal membrane, promoting lysosome acidification. Although caspase-1 is critical for lysosome acidification, its activation is independent of inflammasomes and cell death mediated by apoptosis-associated speck-like protein containing a caspase recruitment domain, revealing a role beyond pyroptosis. In lupus-prone murine macrophages, chronic mTORC2 activity decouples the signaling pathway, leaving Rab39a intact. As a result, the lysosome does not acidify, and degradation is impaired, thereby heightening the burden of immune complexes that activate FcγRI and sustain mTORC2 activity. This feedforward loop promotes chronic immune activation, leading to multiple lupus-associated pathologies. In summary, these findings identify the key molecules in a previously unappreciated signaling pathway that promote lysosome acidification. It also shows that this pathway is disrupted in systemic lupus erythematosus.
Traspatios campesinos de Morelos
Authors: Cobo González Rosario , Paz Paredes Lorena 
Published: June 2018

En este artículo se analiza el carácter multifuncional del traspatio campesino en comunidades de varias regiones morelenses. El traspatio también llamado solar, huerta o calmile en náhuatl, es un área cercana a la vivienda donde se producen alimentos, condimentos, plantas medicinales y flores; que, dependiendo del ciclo agrícola, ritual y familiar, se usa para criar animales, como bodega, lugar de recreo, descanso, convivencia y alojamiento de peregrinos. Sitio ligado al universo femenino y extensión de las tareas domésticas y del cuidado, que conserva y potencia la biodiversidad de la zona, los saberes y prácticas locales. La variedad de especies animales y vegetales que albergan los traspatios se relaciona con sus dimensiones, el clima de la zona, el tipo de suelo y, sobre todo, con los gustos y tradiciones culturales de la familia y la comunidad. A pesar de la modernidad, la urbanización y el crecimiento poblacional de localidades cercanas a los centros urbanos, las familias, principalmente las mujeres, los han preservado, pues les proporcionan seguridad alimentaria y cierta autonomía del mercado, servicios ambientales (microclimas, retención de agua y mejoramiento de suelos, captura de carbono, etc.), plantas medicinales, ornamentales, y ocasionalmente algún ingreso por la ventas de sus productos en pequeña escala.

Abstract. Concentrations and
δ34S values for SO2 and size-segregated sulfate aerosols were determined for air monitoring station
13 (AMS 13) at Fort MacKay in the Athabasca oil sands region, northeastern
Alberta, Canada as part of the Joint Canada-Alberta Implementation Plan for
Oil Sands Monitoring (JOSM) campaign from 13 August to 5 September 2013.
Sulfate aerosols and SO2 were collected on filters using a
high-volume sampler, with 12 or 24 h time intervals. Sulfur dioxide (SO2) enriched in 34S was exhausted by a chemical
ionization mass spectrometer (CIMS) operated at the measurement site and
affected isotope samples for a portion of the sampling period. It was
realized that this could be a useful tracer and samples collected were
divided into two sets. The first set includes periods when the CIMS was not
running (CIMS-OFF) and no 34SO2 was emitted. The second set is for
periods when the CIMS was running (CIMS-ON) and 34SO2 was expected
to affect SO2 and sulfate high-volume filter samples. δ34S values for sulfate aerosols with diameter D>0.49 µm
during CIMS-OFF periods (no tracer 34SO2 present) indicate the
sulfur isotope characteristics of secondary sulfate in the region. Such
aerosols had δ34S values that were isotopically lighter (down to
−5.3 ‰) than what was expected according to potential sulfur
sources in the Athabasca oil sands region (+3.9 to +11.5 ‰).
Lighter δ34S values for larger aerosol size fractions are contrary
to expectations for primary unrefined sulfur from untreated oil sands
(+6.4 ‰) mixed with secondary sulfate from SO2 oxidation
and accompanied by isotope fractionation in gas phase reactions with OH or
the aqueous phase by H2O2 or O3. Furthermore, analysis of
34S enhancements of sulfate and SO2 during CIMS-ON periods
indicated rapid oxidation of SO2 from this local source at ground
level on the surface of aerosols before reaching the high-volume sampler or
on the collected aerosols on the filters in the high-volume sampler.
Anti-correlations between δ34S values of dominantly secondary
sulfate aerosols with D< 0.49 µm and the concentrations of Fe
and Mn (r = −0.80 and r = −0.76, respectively) were observed,
suggesting that SO2 was oxidized by a transition metal ion (TMI)
catalyzed pathway involving O2 and Fe3+ and/or
Mn2+, an oxidation pathway known to favor lighter sulfur isotopes. Correlations between SO2 to sulfate conversion ratio (F(s)) and the
concentrations of α-pinene (r = 0.85), β-pinene
(r = 0.87), and limonene (r = 0.82) during daytime suggests that
SO2 oxidation by Criegee biradicals may be a potential oxidation
pathway in the study region.

Published: June 2018

Abstract. The diameter growth factor (GF) of 100 nm haze particles at 85 % relative
humidity (RH) and their chemical characteristics were simultaneously monitored at
Singapore in October 2015 during a pervasive wildfire haze episode that was
caused by peatland burning in Indonesia. Non-refractory submicron
particles (NR-PM1) were dominated by organics (OA; approximating 77.1 % in
total mass), whereas sulfate was the most abundant inorganic constituent
(11.7 % on average). A statistical analysis of the organic mass spectra
showed that most organics (36.0 % of NR-PM1 mass) were highly
oxygenated. Diurnal variations of GF, number fractions of more hygroscopic
mode particles, mass fractions of sulfate, and mass fractions of oxygenated
organics (OOA) synchronized well, peaking during the day. The mean
hygroscopicity parameter (κ) of the haze particles was
0.189 ± 0.087, and the mean κ values of organics were
0.157 ± 0.108 (κorg, bulk organics) and
0.266 ± 0.184 (κOOA, OOA), demonstrating the important
roles of both sulfate and highly oxygenated organics in the hygroscopic
growth of organics-dominated wildfire haze particles.
κorg correlated with the water-soluble organic fraction
insignificantly, but it positively correlated with f44 (fraction of the
ion fragment at m∕z 44 in total organics) (R = 0.70), implying the
oxygenation degree of organics could be more critical for the water uptake of
organic compounds. These results further suggest the importance of sulfate
and secondary organic aerosol formation in promoting the hygroscopic growth
of wildfire haze particles. Further detailed size-resolved as well as
molecular-level chemical information about organics is necessary for the
profound exploration of water uptake by wildfire haze particles in equatorial Asia.

Abstract. Air quality observations are performed globally to monitor the status of the
atmosphere and its level of pollution and to assess mitigation strategies.
Regulations of air quality monitoring programmes in various countries demand
high-precision measurements for harmful substances often at low trace
concentrations. These requirements can only be achieved by using high-quality
calibration gases including high-purity zero gas. For volatile organic
compound (VOC) observations, zero gas is defined as being hydrocarbon-free
and can be, for example,
purified air, nitrogen or helium. It is essential for the characterisation of
the measurement devices and procedures, for instrument operation as well as
for calibrations. Two commercial and one self-built gas purifiers were tested
for their VOC removal efficiency following a standardised procedure. The
tested gas purifiers included one adsorption cartridge with an inorganic
media and two types of metal catalysts. A large range of VOCs were
investigated, including the most abundant species typically measured at air
monitoring stations. Both catalysts were able to remove a large range of VOCs
whilst the tested adsorption cartridge was not suitable to remove light
compounds up to C4. Memory effects occurred for the adsorption
cartridge when exposed to higher concentration. This study emphasises the
importance of explicitly examining a gas purifier for its intended application
before applying it in the field.
Methane-oxidizing seawater microbial communities from an Arctic shelf
Authors: Uhlig Christiane , Kirkpatrick John B. , D'Hondt Steven , Loose Brice 
Published: June 2018

Abstract. Marine microbial communities can consume dissolved methane
before it can escape to the atmosphere and contribute to global warming.
Seawater over the shallow Arctic shelf is characterized by excess methane
compared to atmospheric equilibrium. This methane originates in sediment,
permafrost, and hydrate. Particularly high concentrations are found beneath
sea ice. We studied the structure and methane oxidation potential of the
microbial communities from seawater collected close to Utqiagvik, Alaska, in
April 2016. The in situ methane concentrations were
16.3 ± 7.2 nmol L−1, approximately 4.8 times oversaturated
relative to atmospheric equilibrium. The group of methane-oxidizing bacteria
(MOB) in the natural seawater and incubated seawater was
> 97 % dominated by Methylococcales (γ-Proteobacteria). Incubations of seawater under a range of methane
concentrations led to loss of diversity in the bacterial community. The
abundance of MOB was low with maximal fractions of 2.5 % at 200 times
elevated methane concentration, while sequence reads of non-MOB methylotrophs
were 4 times more abundant than MOB in most incubations. The abundances of
MOB as well as non-MOB methylotroph sequences correlated tightly with the
rate constant (kox) for methane oxidation, indicating that
non-MOB methylotrophs might be coupled to MOB and involved in community
methane oxidation. In sea ice, where methane concentrations of
82 ± 35.8 nmol kg−1 were found, Methylobacterium
(α-Proteobacteria) was the dominant MOB with a relative abundance of
80 %. Total MOB abundances were very low in sea ice, with maximal
fractions found at the ice–snow interface (0.1 %), while
non-MOB methylotrophs were present in abundances similar to natural seawater
communities. The dissimilarities in MOB taxa, methane concentrations, and
stable isotope ratios between the sea ice and water column point toward different
methane dynamics in the two environments.
Farklı Profilaktik Parlatma İşlemlerinin Mikrohibrit ve Nanohibrit Kompozit Rezinlerin Yüzey Pürüzlülüğü Üzerine Etkisi
Authors: YAMANEL Kıvanç 
Published: June 2018

Amaç: Bu
çalışmanın amacı, farklı profesyonel dental profilaksi işlemlerinin bir
mikrohibrit (Charisma, Heraeus-Kulzer) ve bir nanohibrit (Ice, SDI Dental)
kompozit rezinin yüzey pürüzlülüğü üzerine etkisini değerlendirmektir.Gereç ve Yöntem: Her
restoratif materyalden 45 adet disk şekilli örnek (2 mm kalınlık ve 8 mm
çapında, toplam 90 örnek) plastik kalıplar kullanılarak hazırlandı. Örneklerin
bir yüzü orta, ince ve ultra ince grenli Sof-Lex (3M-ESPE) disklerle parlatıldı
ve her kompozitten 45 örnek rastgele beş gruba ayrıldı (n=9). İlk gruba
profilaksi işlemi uygulanmadı ve kontrol grubu olarak kullanıldı. Diğer
gruplar, Detartrine patı (Septodont), Gelato patı (Keystone Industries) ve
pomza-su karışımının dönen lastiklerle uygulandığı ve pomza-su karışımının
dönen fırçalarla uygulandığı profilaksi işlemlerine tabi tutuldu. Profilaksi
işlemlerinden sonra bütün örneklerin yüzey pürüzlülük değerleri bir optik
profilometre (Zygo New View 7200, Ametek) kullanılarak ölçüldü. Elde edilen
veriler Mann Whitney U ve Kruskal-Wallis testleriyle istatistiksel olarak
analiz edildi. Bulgular: Her
iki kompozit rezin için en pürüzsüz
yüzeyler kontrol gruplarında gözlemlendi (p&lt;0.05). Test edilen kompozit
rezinlerin kontrol gruplarının yüzey pürüzlülük değerleri birbirinden anlamlı
derecede farklıydı (p&lt;0.001). Bununla birlikte aynı profilaksi işlemlerinin
uygulandığı mikrohibrit ve nanohibrit kompozit
rezinlerin yüzey pürüzlülük değerleri arasında istatistiksel olarak anlamlı
derecede farklılık yoktu. Gelato patı, dönen lastik ve fırçayla uygulanan
pomza-su karışımı kontrol grubuna oranla anlamlı derecede yüksek Ra değerlerine
neden olmuştur fakat Detartrine ile elde edilen Ra değerleri her iki kompozitte
de kontrol grubundan anlamlı derecede farklı değildir.

Sonuç: Çalışmada
test edilen bütün profilaksi işlemleri, her iki kompozitte de yüzey pürüzlülük
değerlerini bakterilerin retansiyonuna neden olabilecek seviyeye kadar
yükseltmiştir. Bu sebeple diş hekimleri profilaksi işlemleri sırasında dikkatli
davranmalıdır aksi taktirde profilaksi sonrası kompozit rezinlerin yeniden
parlatılması veya nadiren de yenilenmesi gerekecektir.
