Commentary: Integrating Diagnostic Ultrasound into Athletic Training Education Programs
Authors: Bliven Kellie C. Huxel , Anderson Barton E. , Makin Inder Raj S.
Published: January 2019

Context:

The use of point-of-care ultrasound (POCUS) is increasingly becoming a standard of care for sports medicine and orthopedic physicians. As such, there will be increased demand for athletic trainers to have knowledge and skills in diagnostic ultrasound.

Objective:

To provide key considerations for integration of diagnostic ultrasound into athletic training education and address challenges and barriers to such integration.

Background:

Advancements in designing portable, user-friendly ultrasound units have enabled clinicians to perform POCUS as an adjunct to the physical exam, resulting in improved patient care. Increased demands for POCUS across medicine have prompted medical schools to integrate diagnostic ultrasound throughout the curriculum, providing athletic training education programs a framework to consider within their curriculum.

Synthesis:

Integrating diagnostic ultrasound throughout the curriculum provides focused experiences to prepare, conduct, and link imaging to clinical and physical exam skills. Diagnostic ultrasound has a role in visualizing structures in an anatomy course, as an adjunct to physical exam in medical conditions, orthopedic exam, and diagnosis courses, and as a visual feedback tool in rehabilitation courses, thus enabling it to be integrated throughout existing curriculum. Barriers to diagnostic ultrasound include cost, time, and faculty expertise.

Results:

Cost sharing or use of ultrasound simulators can overcome cost barriers. Use of online educational modules to deliver content virtually is effective and allows face-to-face time to be spent in hands-on experiential learning. Finally, developing interprofessional partnerships to “teach the teacher” is an effective model in teaching faculty about diagnostic ultrasound.

Recommendation(s):

Educational programs should consider ways to overcome barriers and integrate diagnostic ultrasound into curriculum equipping future athletic trainers with knowledge and skills for POCUS, thus increasing their effectiveness on a health care team.

Conclusion(s):

Proactive integration of diagnostic ultrasound into athletic training education will equip graduates to add value to a health care team.
Educational Technique: Using a Phased Approach to Integrate Diagnostic Ultrasound into Athletic Training Education
Authors: Bliven Kellie C. Huxel , Anderson Barton E. , Richter Saskia D. , Makin Inder Raj S.
Published: January 2019

Context:

The use of point-of-care diagnostic ultrasound is increasing in health care, specifically among sports medicine clinicians as an adjunct to the physical exam. Given the role of athletic trainers in interdisciplinary sports medicine teams, athletic training educational programs should consider integrating this noninvasive imaging modality into curricula.

Objective:

To provide a framework for integrating diagnostic ultrasound imaging content into existing athletic training curricula.

Background:

A phased approach to incorporating ultrasound imaging into existing courses with minimal disruption is important for adoption. Foundational knowledge for skill performance begins with early exposure to ultrasound concepts and is followed by phased integration of hands-on ultrasound imaging into athletic training courses.

Description:

Content delivery considerations, such as online modules and technology needs, to enhance hands-on learning is discussed. Examples of integrating diagnostic ultrasound imaging throughout the curriculum, including anatomy, clinical assessment, and manual therapy courses, are provided.

Clinical Advantage(s):

Integrating ultrasound throughout curricula teaches students how to use and interpret ultrasound images as an adjunct to physical exam, enhancing the athletic trainer's value on a health care team and improving clinical practice. Ultrasound imaging can also be used as a valuable feedback mechanism during the performance of hands-on athletic training skills, including special tissue tests and manual therapy techniques.

Conclusion(s):

Following initial exposure to ultrasound imaging, the inclusion of diagnostic ultrasound instruction in athletic training curricula can expose students to ultrasound imaging, basic concepts, transducer characteristics, and image interpretation, which is a valuable adjunct to clinical practice.
Diseñando Mundos Transmedia: el caso Plot 28 (2013)
Authors: Hernández Ruiz Javier
Published: January 2019

A la hora de configurar universos transmediáticos es necesario diseñar un mapa de contenidos acompasado a un diseño de plataformas y canales con su potencial incidencia en la audiencia. Para ello se debe operar paralelamente entre los despliegues narrativos y el diseño de producción, que incluye la línea estética, los dispositivos tecnológicos y el diseño de audiencias potenciales. En este artículo convergen esas dos amplias perspectivas, la del diseñador de producción y la del storyteller, indagando en los procesos conjuntos que operan a la hora de construir una arquitectura de contenidos transmediales, operación en la que hay que ir de la mano de las consiguientes soluciones tecnológicas. Todo ello se concreta en el caso de estudio Plot 28, un universo transmedia pionero en lengua española que se lanzó en enero de 2013 asociado a un formato de creación transmedial (Ficción total). La experiencia creadora interactúa con la aproximación analítica y teórica para ofrecer una poco frecuente perspectiva enriquecida al estudio del caso. De esa manera se abordarán, desde una praxis creadora ya contrastada pero justificada por las más últimas aproximaciones teóricas y hermenéuticas, las estrategias narrativas, de interacción y de gamificación, la gestión de los contenidos y su escalabilidad, el diseño de los mapas de navegación, la búsqueda de la empatía de la audiencia con el mundo diegético diseñado. Todo ello acompañados de datos extraídos de fuentes directas en esta experiencia de producción y de difusión que puede iluminar proyectos futuros.

Etanercept to Control Inflammation in the Treatment of Complicated Neurocysticercosis
Authors: Nash Theodore E. , Ware JeanAnne M. , Coyle Christina M. , Mahanty Siddhartha
Published: January 2019

Manifestations of neurocysticercosis (NCC) are primarily due to host inflammatory responses directed at drug-damaged or naturally degenerating metacestodes (cysts) of the tapeworm Taenia solium. Prolonged high-dose corticosteroids are frequently required to control this inflammation in complicated disease, often causing severe side effects. Studies evaluating alternatives to corticosteroids are lacking. Here, we describe the clinical course of NCC in 16 patients prescribed etanercept (ETN), a tumor necrosis factor-alpha inhibitor to control inflammation resulting from anthelmintic treatment. Twelve patients with extraparenchymal NCC were administered ETN with corticosteroids (11/12, 91.7%) and/or methotrexate (9/12, 75.0%). The median age of the subgroup with extraparenchymal NCC was 40 years (range 26–57 years) and 66.7% were male. They were administered ETN for a median period of 311 days (range 31–461 days) and then followed for a median of 3.4 years (range 0.3–6.6 years). Among nine assessable patients, all improved clinically after starting ETN and one deteriorated transiently. Of the remaining three, one was lost to follow-up and two patients have improved but had not completed their assigned course. Four additional persons with recurrent perilesional edema (PE) episodes were given ETN for a median of 400.5 days (range 366–854 days) and followed post-ETN for a median of 1.7 years (range 0.2–2.4 years). All PE patients improved and two successfully tapered corticosteroids. Etanercept administration was associated with clinical improvement, stable disease, absence of recurrence, and lack of serious side effects. Etanercept appears to contribute to the control of inflammation and facilitate corticosteroid taper.

Za celotno območje je značilen pretočni kras, kjer podzemni tokovi, ki ponikajo na Duvanjskem polju, odtekajo v smeri izvirov na Livanjskem polju. V tej raziskavi smo izdelali morfografske in morfometrične analize površinskih in podzemskih oblik, predvsem udornic, denudiranih jam ter aktivnih in reliktnih jamskih sistemov. Interpretirali smo morfogenezo in preteklo hidrološko delovanje proučevanega območja.
The Role of Motion Verbs in Conveying Path-Related Information in English and Slovene Fictive Motion Expressions
Authors: Lipovšek Frančiška
Published: January 2019

The paper presents a study on fictive motion (FM) uses of motion verbs in English and slovene from the point of view of conveying path-related information. An FM expression describes a static scene in terms of motion (e.g. The road weaves through a range of hills). Motion verbs in FM uses do not describe actual motion events, but may refer to certain properties of the path by virtue of their meanings. English and slovene FM expressions exhibit different behaviours in this respect. Many English verbs display meaning components that can be metonymically mapped onto the properties of the path. The meanings of slovene verbs are less specific, so that such properties need to be expressed verb-externally in slovene FM expressions.
Developing EFL Writing with Year 5 Pupils by Writing Summaries
Authors: Puhner Nataša , Dagarin Fojkar Mateja
Published: January 2019

Developing EFL writing skills in primary school pupils is one of the most demanding and time consuming challenges that foreign language teachers face. The main aim of this study was thus to analyse 64 written summaries of Year 5 pupils in terms of content, structure, length and most often used words. In order to achieve the aim of pupils being able to write a summary of a story individually and in a given time frame, the task was approached gradually and systematically throughout the school year. The results show that most of the pupils managed to finish a structurally organized summary and most of them wrote a summary which included the most important aspects regarding the content of the story. The results of the survey indicate that a systematic approach to writing summaries helps pupils in developing their writing skills.
Toponimsko popotovanje po Sloveniji na primeru nemškega turističnega vodnika
Authors: Rieger Mladen
Published: January 2019

Dobrih 35 let po izdaji prvega in do danes edinega sistematičnega dela, posvečenega prevajanju slovenskih toponimov v nemščino, je treba na novo analizirati rabo kulturnospecifičnih izrazov v turističnih vodnikih po Sloveniji, primerjati rabo toponimov z dognanji prevodne stroke ter opozoriti na neustrezne prevodne rešitve. Izsledke take raziskave je mogoče s pridom uporabiti tudi pri izobraževanju študentov prevajalstva.Toponimi so še bolj kot druge realije vezani na kraje in pokrajine; z njimi namreč skušamo poimenovati pojme, v katerih se prepletajo zgodovinske, kulturne in družbene niti tako kolektivnega kot tudi individualnega spomina. Torej bi bilo napačno pričakovati, da je gradnja in urejanje slovarja toponimov, če se le-ti pojavijo v prevodih ali tujejezičnih besedilih, zgolj naloga ciljnega jezika in kulture. V pričujočem prispevku skušam s pomočjo primerov analizirati neustrezne ali manj ustrezne prevodne rešitve, opozoriti na značilne težave in nakazati možne strategije pri prevajanju tujejezičnih toponimov.
Analiza odgovorov z imenskimi kolokacijami v hrvaščini kot J2
Authors: Ordulj Antonia
Published: January 2019

Prispevki, ki obravnavajo razvoj kolokacijske kompetence v hrvaščini kot drugem in tujem jeziku (J2), niso številni, zato še ni narejena tipologija kolokacijskih odstopanj kot tudi ne tipologija različnih vrst v preverjanjih dobljenih odgovorov. Prav zato je cilj prispevka analiza različnih vrst odgovorov pri produktivnih nalogah, s katerimi preverjamo poznavanje imenskih kolokacij glede na njihovo pogostost, asociativno moč in raven znanja jezika. V analizi odgovorov smo zajeli tri produktivne naloge: 1) izolirane stavke s kolokacijami v imenovalniku, 2) izolirane stavke s kolokacijami v odvisnih sklonih in 3) kolokacije v širšem kontekstu. Odgovori sodelujočih v raziskavi so razvrščeni v tri kategorije (leksikalno, slovnično in kombinirano), znotraj katerih smo razlikovali različna odstopanja. Analizo smo na vzorcu 70 tujih govorcev hrvaščine, ki imajo raven znanja B2 in B1, izvedli za imenske kolokacije, kjer je osnova samostalnik, kolokat pa pridevnik. Preden smo izdelali analitična orodja, smo naredili dve predhodni raziskavi: analizo kolokacij v dveh korpusih (CROLTEC in hrWaC) ter določitev asociativne moči kolokacij na vzorcu rojenih govorcev hrvaščine. Ugotovimo lahko, da na obeh ravneh znanja prevladuje visok odstotek napačnih odgovorov in kolokatorjev v nalogah, kjer ni podan kontekst (KIK). Kljub temu je potrebno omeniti, da je, ne glede na pogostost in asociativno moč kolokacij, odstotek pravilnih odgovorov pri vseh nalogah višji na ravni B2 kot na ravni B1.
Uporaba logičnih konektorjev v akademskem pisanju makedonskih učencev angleščine
Authors: Stojanovska-Ilievska Natasha
Published: January 2019

V besedilu raziskujemo, kako makedonski študenti angleščine v akademskem pisanju uporabljajo logične konektorje. Logični konektorji so v tem besedilu določeni kot vrsta kohezivnih sredstev “ki sami zelo malo prispevajo ali sploh ne prispevajo k propozicionalni vsebini, ampak pomagajo določiti odnose med stavki v ustnem in pisnem diskurzu” (Celce-Murcia & Larsen-Freeman, 1999: 519). V članku predstavljamo analizo besedil makedonskih študentov angleščine, ki v drugem letniku študija kot del študijskega programa obiskujejo predavanja iz akademskega pisanja. Osredotočamo se zlasti na naslednje tipe logičnih konektorjev: dodajalne, protivne, vzročne ter časovne. Namen študije je analiza pogostosti logičnih konektorjev, njihove razporeditve v omenjene štiri kategorije, pa tudi analiza ustreznosti njihove uporabe v določenem kontekstu. V članku analiziramo rezultate in skušamo predstaviti morebitne vzroke pogoste oziroma nepogoste rabe posameznih konektorjev. Rezultate primerjamo z rezultati podobnih študij, opravljenih na vzorcih akademskih pisnih izdelkov rojenih in tujih govorcev angleščine. V zadnjem delu predstavljamo tudi pedagoške implikacije študije.
Preverjanje in ocenjevanje ustnih in pisnih jezikovnih kompetenc pri zgodnjem pouku tujega jezika
Authors: Jazbec Saša , Kacjan Brigita
Published: January 2019

Zgodnje učenje tujega jezika je v večini evropskih držav postalo paradigma šolskega vsakdanjika. Medtem ko je bilo zgodnje učenje tujega jezika še pred desetletji označeno za sporno in diskutabilno, danes vemo, da ima bistveno več prednosti kot slabosti. Stroka pa še vedno razpravlja o relevantnih metodah, ki vodijo, upoštevajoč specifiko in okoliščine ter spremenljivke zgodnjega pouka tujega jezika (izhodiščni, ciljni jezik, trajanje pouka, število učencev itd.), k optimalnim rezultatom. Namen tega prispevka je obravnava pomembne teme v okviru zgodnjega učenja, to sta preverjanje in ocenjevanje kot obvezna dela zgodnjega učenja tujega jezika, katerih izvajanje je še posebno subtilno. V prispevku bodo predstavljeni in analizirani praktični primeri oz. instrumenti za ocenjevanje in preverjanje ustnih in pisnih jezikovnih kompetenc pri zgodnjem pouku tujega jezika, obenem pa bodo izpostavljene njihove prednosti in slabosti.
Hrepenenje in ljubezen v Lancelot und Ginover
Authors: Ponikvar Carmen Bianca
Published: January 2019

Hrepenenje in ljubezen sta emociji, ki se pojavljata v mnogo romanih o kralju Arturju. Na like lahko učinkujeta tako pozitivno kot negativno. Po eni strani ljubezen spodbuja viteze k boju in služenju svoji dami, saj si s svojimi bojnimi dejanji poskušajo pridobiti njeno naklonjenost, po drugi strani pa jih ločitev od ljubljene ali hrepenenje po njeni ljubezni »spravlja ob pamet«, jih slabi, odvrača od boja, kar se pogosto konča z boleznijo. Ta dualistični značaj ljubezni in hrepenenja v Prosalancelotu analiziramo ob ljubezenskem razmerju med Lancelotom in Ginover ter ob prijateljstvu med Lancelotom in Galahotom. Analiza vključuje razpravo, kako ti dve emociji vplivata na like in v kakšni meri usmerjata njihovo ravnanje. Lancelot je še posebej izstopajoč lik, ker nanj čustva močno vplivajo. Strastna ljubezen in hrepenenje po kraljici Ginover usmerjata njegovo celotno življenje in hkrati vplivata na to, kako ga zaznavajo drugi liki.
Praksa ocenjevanja znanja pri tujem jeziku stroke v slovenskem visokošolskem prostoru
Authors: Svetlin Gvardjančič Polona
Published: January 2019

Zanimanje za ocenjevanje znanja se je v zadnjih desetletjih povečalo, tako na področju terciarnega izobraževanja kot na področju tujih jezikov stroke. V teoretičnem delu smo osvetlili razloge za ta premik in opozorili na ključne teme, ki zanimajo raziskovalce na omenjenem področju. Z raziskavo smo opravili posnetek stanja pri ocenjevanju znanja tujega jezika stroke na visokošolskih ustanovah v Sloveniji. Rezultati potrjujejo osrednjo vlogo učitelja tujega jezika stroke pri vseh opravilih, ki zadevajo ocenjevanje znanja: odločanje o načinih, priprava testov in podelitev ocene. Praksa ocenjevanja znanja kaže na to, da učitelji v ocenjevanje znanja pozorno vključujejo teme, ki so relevantne za stroko, katere jezik predavajo, v izvedbenem delu pa sledijo trendom v pedagoški stroki, kar se odraža v uporabi različnih oblik ocenjevanja. Kljub temu, da se jim zdi primerno, da sami odločajo o ocenjevanju znanja, pa si želijo več sodelovanja in izmenjave izkušenj s kolegi.

Percepcija in definicija: rdeče (rouge) in infrardeče (infrarouge) v francoskih slovarjih
Authors: Paolini Michele
Published: January 2019

V prispevku obravnavamo definicije leksemov rdeče (rouge) in infrardeče (infrarouge), ki sta si navidezno blizu na ravni označenca in označevalca. Kar razlikuje pomen obeh besed, ni le raba in sprejemanje (splošno védenje proti ekspertnemu znanju), pač pa tudi drugačen način razumevanja, saj se pomen leksema infrardeče (infrarouge) nanaša na realnost, ki je z vidom ne moremo zaznati. V primeru infrarouge se znanstvena definicija zdi nujna, pomen leksema rdeče pa pripada splošnemu besedišču. Definicija besede rdeče (rouge) pravzaprav predmetom pripisuje kromatične lastnosti, ki jih z znanstvenega vidika nimajo; v fiziki namreč barva ni lastnost predmeta, pač pa dolžina valov.
Thermal structure of the mesopause region during the WADIS-2 rocket campaign

Published: January 2019

Abstract. This paper presents simultaneous temperature measurements by three
independent instruments during the WADIS-2 rocket campaign in northern Norway
(69∘ N, 14∘ E) on 5 March 2015. Vertical profiles
were measured in situ with the CONE instrument. Continuous mobile IAP Fe lidar (Fe
lidar) measurements during a period of 24 h, as well as horizontally resolved temperature maps by the Utah State University (USU) Advanced
Mesospheric Temperature Mapper (AMTM) in the mesopause region, are analysed.
Vertical and horizontal temperature profiles by all three instruments are in
good agreement. A harmonic analysis of the Fe lidar measurements shows the
presence of waves with periods of 24, 12, 8, and 6 h.
Strong waves with amplitudes of up to 10 K at 8 and
6 h are found. The 24 and 12 h components play only a
minor role during these observations. In contrast only a few short periodic
gravity waves are found. Horizontally resolved temperatures measured with the
AMTM in the hydroxyl (OH) layer are used to connect the vertical temperature profiles.
In the field of view of 200 km×160 km only small deviations from
the horizontal mean of the order of 5 K are found. Therefore only weak
gravity wave signatures occurred. This suggests horizontal structures of more
than 200 km. A comparison of Fe lidar, rocket-borne measurements, and
AMTM temperatures indicates an OH centroid altitude of about 85 km.
Atmospheric bending effects in GNSS tomography
Authors: Möller Gregor , Landskron Daniel
Published: January 2019

Abstract. In Global Navigation Satellite System (GNSS) tomography, precise information about the tropospheric water vapor
distribution is derived from integral measurements like ground-based GNSS
slant wet delays (SWDs). Therefore, the functional relation between
observations and unknowns, i.e., the signal paths through the atmosphere, have
to be accurately known for each station–satellite pair involved. For GNSS
signals observed above a 15∘ elevation angle, the signal path is well
approximated by a straight line. However, since electromagnetic waves are
prone to atmospheric bending effects, this assumption is not sufficient
anymore for lower elevation angles. Thus, in the following, a mixed 2-D
piecewise linear ray-tracing approach is introduced and possible error
sources in the reconstruction of the bended signal paths are analyzed in more
detail. Especially if low elevation observations are considered, unmodeled
bending effects can introduce a systematic error of up to 10–20 ppm, on
average 1–2 ppm, into the tomography solution. Thereby, not only the
ray-tracing method but also the quality of the a priori field can have a
significant impact on the reconstructed signal paths, if not reduced by
iterative processing. In order to keep the processing time within acceptable
limits, a bending model is applied for the upper part of the neutral
atmosphere. It helps to reduce the number of processing steps by up to 85 %
without significant degradation in accuracy. Therefore, the developed
mixed ray-tracing approach allows not only for the correct treatment of low
elevation observations but is also fast and applicable for near-real-time
applications.

Abstract. Radiometric calibration of space-based elastic backscatter lidars is
accomplished by comparing the measured backscatter signals to theoretically
expected signals computed for some well-characterized calibration target. For
any given system and wavelength, the choice of calibration target is dictated
by several considerations, including signal-to-noise ratio (SNR) and target
availability. This paper describes the newly implemented procedures used to
calibrate the 1064 nm measurements acquired by CALIOP (i.e., the
Cloud-Aerosol Lidar with Orthogonal Polarization), the two-wavelength (532
and 1064 nm) elastic backscatter lidar currently flying on the Cloud-Aerosol
Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) mission.
CALIOP's 532 nm channel is accurately calibrated by normalizing the
molecular backscatter from the uppermost aerosol-free altitudes of the CALIOP
measurement region to molecular model data obtained from NASA's Global
Modeling and Assimilation Office. However, because CALIOP's SNR for molecular
backscatter measurements is prohibitively lower at 1064 nm than at 532 nm,
the direct high-altitude molecular normalization method is not a viable
option at 1064 nm. Instead, CALIOP's 1064 nm channel is calibrated relative
to the 532 nm channel using the backscatter from a carefully selected subset
of cirrus cloud measurements. In this paper we deliver a full account of the
revised 1064 nm calibration algorithms implemented for the version 4.1 (V4)
release of the CALIPSO lidar data products, with particular emphases on the
physical basis for the selection of “calibration quality” cirrus clouds and
on the new averaging scheme required to characterize intra-orbit calibration
variability. The V4 procedures introduce latitudinally varying changes in the
1064 nm calibration coefficients of 25 % or more, relative to previous
data releases, and are shown to substantially improve the accuracy of the V4
1064 nm attenuated backscatter coefficients. By evaluating calibration
coefficients derived using both water clouds and ocean surfaces as alternate
calibration targets, and through comparisons to independent, collocated
measurements made by airborne high spectral resolution
lidar, we conclude that the CALIOP V4 1064 nm calibration
coefficients are accurate to within 3 %.
Stand age and species composition effects on surface albedo in a
mixedwood boreal forest

Published: January 2019

Abstract. Surface albedo is one of the most important processes governing climate forcing in the boreal forest and is directly affected by management activities such as harvesting and natural disturbances such as forest fires. Empirical data on effects of these disturbances on boreal forest albedo are sparse. We conducted ground-based measurements of surface albedo from a series of instrument towers over four years in a replicated chronosequence of mixedwood boreal forest sites differing in stand age (year since disturbance) in both post-harvest and post-fire stands. We investigated the effects of stand age, canopy height, tree species composition, and ground vegetation cover on surface albedo through stand development. Our results indicate that winter and spring albedo values were 63 and 24 % higher, respectively, in post-harvest stands than in post-fire stands. Winter and summer albedos saturated at ~ 50 years of stand age in both post-harvest and post-fire stands. Albedo differences between post-harvest and post-fire stands were most pronounced during winter and spring in young stands (0–19 years post-disturbance). The proportion of deciduous broadleaf species showed a strong positive relationship with seasonal albedo in both post-harvest and post-fire stands. Given that stand composition in mixedwood boreal forests generally shows a gradual replacement of deciduous trees by conifers, our results suggest that successional changes in species composition are likely a key driver of age-related patterns in albedo. Our findings also suggest the efficacy of increasing the proportion of deciduous broadleaf species as a silvicultural option for climate-friendly management of boreal forest.
Floodwater Impact on Galveston Bay Phytoplankton Taxonomy, Pigment Composition
and Photo-Physiological State following Hurricane Harvey from Field and Ocean Color (Sentinel-3A OLCI) Observations

Published: January 2019

Abstract. Phytoplankton taxonomy, pigment composition and photo-physiological state were studied in Galveston Bay (GB), Texas (USA) following the extreme flooding associated with Hurricane Harvey (August 25–29, 2017) using field and satellite ocean color observations. Percentage of chlorophyll a (Chl a) in different phytoplankton groups were determined from a semi-analytical IOP (inherent optical property) inversion algorithm. The IOP inversion algorithm revealed the dominance of freshwater species (cyanobacteria and green algae) in the bay following the hurricane passage (September 29, 2017) under low salinity conditions associated with the discharge of floodwaters into GB; 2 months after the hurricane (October 29–30, 2017), under more seasonal salinity conditions, the phytoplankton community transitioned to an increase in small sized groups such as haptophyte and prochlorophyte. Sentinel-3A OLCI-derived Chl a obtained using a red/NIR band ratio algorithm for the turbid estuarine waters was highly correlated (R2 > 0.90) to HPLC-derived Chl a concentrations. A Non-Negative Least Square (NNLS) inversion model was then applied to OLCI-derived Chl a maps of GB to obtain spatiotemporal distributions of phytoplankton diagnostic pigments; results appeared consistent with extracted phytoplankton taxonomic composition derived from the IOP inversion algorithm. OLCI-derived diagnostic pigment distributions also exhibited good agreement with HPLC measurements, with mean R2 ranging from 0.39 for violaxanthin to 0.98 for Chl a. Environmental factors (e.g. floodwaters) combined with phytoplankton taxonomy also strongly modulated phytoplankton physiology in the bay as indicated by measurements of photosynthetic parameters with a Fluorescence Induction and Relaxation (FIRe) system. Phytoplankton in well-mixed waters (mid-bay area) exhibited maximum PSII photochemical efficiency (FV/FM) and low effective absorption cross section (δPSII), while the areas adjacent to the shelf (likely nutrient-limited) showed low FV/FM and elevated values. Overall, the approach using field and ocean color data combined with inversion models allowed, for the first time, an assessment of phytoplankton response to a large hurricane-related floodwater perturbation in a turbid estuarine environment based on its taxonomy, pigment composition and physiological state.
Implications of water management representations for watershed hydrologic modeling in the Yakima River basin

Published: January 2019

Abstract. Water management substantially alters natural regimes of
streamflow through modifying retention time and water exchanges among
different components of the terrestrial water cycle. Accurate simulation of
water cycling in intensively managed watersheds, such as the Yakima River basin (YRB) in the Pacific Northwest of the US, faces challenges in
reliably characterizing influences of management practices (e.g., reservoir
operation and cropland irrigation) on the watershed hydrology. Using the Soil
and Water Assessment Tool (SWAT) model, we evaluated streamflow simulations
in the YRB based on different reservoir operation and irrigation schemes.
Simulated streamflow with the reservoir operation scheme optimized by the
RiverWare model better reproduced measured streamflow than the simulation
using the default SWAT reservoir operation scheme. Scenarios with irrigation
practices demonstrated higher water losses through evapotranspiration (ET)
and matched benchmark data better than the scenario that only considered
reservoir operations. Results of this study highlight the importance of
reliably representing reservoir operations and irrigation management for
credible modeling of watershed hydrology. The methods and findings presented
here hold promise to
enhance water resources assessment that can be applied to other intensively managed watersheds.

El pintor que escribe en un muro de papel: David Alfaro Siqueiros en la Revista Multicolor de los Sábados (1933)
Authors: Mascioto María de los Ángeles
Published: January 2019

El artículo se centra en la participación de David Alfaro Siqueiros en la Revista Multicolor de los Sábados(Argentina). Por un lado, se estudiará la apropiación y resignificación que hace esta publicación periódica de la idea predominante en la propuesta de Siqueiros de “sacar el arte a la calle”; y por otro, se analiza el modo en que en la producción literaria del muralista mexicano, su propuesta política queda opacada por los condicionamientos de la prensa masiva.
Selección y digestión en “revistas de revistas” latinoamericanas (1930-1950)
Authors: Viu Antonia
Published: January 2019

Este trabajo propone que las “revistas de revistas” latinoamericanas de la primera mitad del siglo XX pueden pensarse como sistemas de “digestión” en un sentido material, en tanto digestsde la prensa mundial. Este sistema de “digestión”, basado en el recorte y transposición de materiales de una revista a otra, incluye una variedad de operaciones y exige una metodología de análisis particular. En este artículo se propone una discusión teórico-crítica para pensar cómo opera dicho sistema en estas revistas y una descripción de la metodología desde la que podrían estudiarse, que luego se grafica a partir de dos ejemplos puntuales: en Babel. Revista de revistas (1939-1940), durante su época chilena editada por Enrique Espinoza, y en Ultra. Revista de revistas (1936-1947), la revista cubana dirigida por el etnógrafo Fernando Ortiz.
Algo más sobre el Meridiano editorial hispanoamericano (1927-1928)

Published: January 2019

Given the growth of the elderly population, it is essential that online social networks consider aspects of quality of use to address the unique needs of this audience. Unfortunately, networks, such as Facebook, have been designed largely for younger users, leading to challenges for the elderly in the use of their interfaces.Some human–computer interaction (HCI) research has explored the usability and accessibility of Facebook and its functionalities, including for the elderly. However, there has not been a great deal of research exploring communicability of this social network Facebook for older users. This paper presents the results of a 2015 case study completed in Brazil, in which Facebook’s accessibility and communicability for the elderly were analyzed. As a result of this research, checkpoints are presented to support designers in the construction of virtual spaces for social interaction.
Twenty-first century digital skills for the creative industries workforce: Perspectives from industry experts

Published: January 2019

The creative industries workforce requires employees that use ICT applications to solve the knowledge related tasks at work. The aim of this research is twofold: (1) to see if previously cited twenty-first century digital skills are suited to the creative industries workforce and (2) to investigate the extent to which skill development get attention in current organizational practices. In-depth interviews were conducted with a sample of 24 managers and senior executives of creative organizations based in the Netherlands. As a guideline for the interviews, a conceptual twenty-first century digital skills framework was used. This framework presented the following seven core skills supported by the use of ICT: technical, information management, communication, collaboration, creativity, critical thinking, and problem solving. The following five contextual skills that play a role when using ICT were also presented: ethical awareness, cultural awareness, flexibility, self-direction, and lifelong learning. The results support the importance of twenty-first century digital skills, however, there seems to be insufficient attention to the levels of these skills; they play a minor role during the selection and evaluation procedures. Often it is assumed that existing digital skills are sufficient. Managers are encouraged to improve on developing requirements necessary for future employees as well as measurements to ensure current employees skill levels. The developed framework might be used as a management tool for indicating skills that need to be assessed among professionals working in the creative industries.

Authors: Gachugi Florence Gathoni
Published: January 2019

This paper examines the polysemy that exists in the semantic field of perception verbs in Gĩkũyũ which is a Bantu Language of the Niger – Congo group spoken in Kenya. These verbs do not only convey the meanings that are related to the physical perception of each sense modality but they are extended to express varieties of meanings in other semantic fields. The paper also examines the link between the concrete and the abstract meanings within perception verbs in GĩKũYũ through conceptual metaphor.
The Effect of Organizational Justice on Employees’ Affective Commitment
Authors: Suifan Taghrid S.
Published: January 2019

This study aims to examine the indirect relationship between organizational justice and employees’ affective organizational commitment via the mediating effect of job satisfaction. In the research design, all three dimensions of organizational justice – distributional, procedural, and interactional – were considered. A questionnaire was distributed to 361 employees of pharmaceutical companies in Jordan, with a response rate of 93%. Data from the questionnaires were then analyzed and the study’s hypotheses were tested with structural equation modeling using Amos 20. The results confirmed that job satisfaction plays a mediating role between organizational justice and affective commitment. This accords with the findings of similar studies in developed countries, emphasizing the vital role of organizational justice in shaping employees’ behaviors and attitudes. This study is unique in investigating a concept that has been rarely explored in developing countries. It will help improve the scarcity of such research, especially in the Middle East. The study also urges that future research further tests this model in additional developing contexts to enable more generalized conclusions.

Published: January 2019

This paper presents parents’ views of their young children’s access and use of technological devices, the duration spent on technological devices and the benefits and risks associated with that. 500 parents completed a questionnaire and findings suggest that parents hold positive beliefs about technology with smartphones being the most used among their children and the most effective device, while e-reading was the least used. Findings indicated that parents believe technology benefits their children in developing intellectually, socially, physically and emotionally respectively, thus it enhances children’s educational development through educational activities while they interact with peers at the same time; physical development was number 1 risk on children which was associated to health and mental development. Recommendations were given at the end of the paper to examine in depth how technological devices can used in educational settings in favour of children.
Effects of the geometric shape and placing length of a fiber post on the stress distribution in a mandibular premolar tooth: A finite element analysis study
Authors: Aslan Tuğrul , Esim Emir , Kılıç Kerem , Er Özgür , Yıldırım Şahin
Published: January 2019

Aim: The aim of this study was to evaluate the effects of two geometrically different fiber post systems and two different placing lengths on the stress distribution of endodontically treated teeth.

Methodology: Four different mandibular premolar tooth models were created. These models were restored using oval or circular fiber posts with two different placing lengths. An oblique force of 300 N was applied to the top of the tooth, and von Mises stress evaluations were carried out on the dentin tissue, luting cement, and fiber posts.

Results: The maximum von Mises stresses were observed in the 10-mm long circular fiber post model, while the minimum stresses were seen in the 5-mm long oval fiber post model. In general, the oval fiber post models presented more homogeneous stresses than the circular fiber post models. Moreover, the 10-mm long fiber post models generated greater von Mises stresses than the 5-mm long fiber post models in the dentin tissue and luting cement.

Conclusion: According to the study findings, the use of oval fiber posts at both placing lengths is suggested for oval shaped root canals due to the lower stress concentrations.
