Published: July 2019

Compelling evidence indicates that “active learning” (learning by doing) is an effective pedagogy regardless of discipline or class size, and can be particularly effective with diverse students. This study investigated active learning practices in 64 classes at the University of Hawai‘i at Mānoa, a US university with a highly diverse student body, using a “Passivity Indicator” (PI: ratio of class time spent in passive activities to total class time). For all classes, the mean PI was 43%. Statistical analysis reveals no significant differences in the PI of classes taught in STEM vs. non-STEM disciplines, or between upper vs. lower division courses. However, the PI in larger classes was found to be significantly greater than in small classes (64% vs. 39%, respectively; p=0.02). Moreover, classroom activities aligned with an active learning standard in Language and Literacy Development (e.g., students answering questions) occurred twice as often in small (24%) vs. large classes (12%, with p=0.02). Altogether, these findings indicate an opportunity for more active learning in large classes. We present a range of research-based pedagogical strategies that can be readily implemented in large classrooms, and encourage instructors to use their implementation as research opportunities to gather data on student success.
Variability of bulk water vapor content in the marine cloudy boundary layers from microwave and near-infrared imagery
Authors: Millán Luis F. , Lebsock Matthew D. , Teixeira Joao 
Published: July 2019

Abstract. This work uses the synergy of collocated microwave radiometry and near-infrared imagery to study the marine boundary layer water vapor. The Advanced Microwave Scanning Radiometer (AMSR) provides the total column water vapor, while the Moderate Resolution Imaging Spectroradiometer (MODIS) near-infrared imagery provides the water vapor above the cloud layers. The difference between the two gives the vapor between the surface and the cloud top, which may be interpreted as the boundary layer water vapor under certain conditions. As a by-product of this algorithm, we also store cloud top information of the MODIS pixels used, a proxy for the inversion height, as well as the sea surface temperature and total column water vapor from the AMSR measurements. Hence, the AMSR–MODIS dataset provides several of the variables associated with the boundary layer thermodynamic structure. Comparisons against radiosondes and GPS radio occultation (GPSRO) data demonstrate the robustness of these boundary layer water vapor estimates. We explore the annual cycle of the number of observations as a proxy for stratus cloud amount, in well-known stratus regions; we then exploit the 16 years of AMSR–MODIS synergy to study for the first time the annual variations of the boundary layer water vapor in comparison to the sea surface temperature and the boundary layer cloud top height (equivalent to the inversion height) climatologies, and lastly we explore the climatological behavior of these variables on stratocumulus-to-cumulus transitions.

Published: July 2019

Abstract. We describe a formaldehyde (HCHO) retrieval algorithm for
the Geostationary Environment Monitoring Spectrometer (GEMS) that will be
launched by the Korean Ministry of Environment in 2019. The algorithm
comprises three steps: preprocesses, radiance fitting, and postprocesses.
The preprocesses include a wavelength calibration, as well as interpolation and
convolution of absorption cross sections; radiance fitting is conducted
using a nonlinear fitting method referred to as basic optical absorption
spectroscopy (BOAS); and postprocesses include air mass factor calculations
and bias corrections. In this study, several sensitivity tests are conducted
to examine the retrieval uncertainties using the GEMS HCHO algorithm. We
evaluate the algorithm with the Ozone Monitoring Instrument (OMI) Level 1B irradiance/radiance data by
comparing our retrieved HCHO column densities with OMI HCHO products of the
Smithsonian Astrophysical Observatory (OMHCHO) and of the Quality Assurance
for Essential Climate Variables project (OMI QA4ECV). Results show that OMI
HCHO slant columns retrieved using the GEMS algorithm are in good agreement
with OMHCHO, with correlation coefficients of 0.77–0.91 and regression
slopes of 0.94–1.04 for March, June, September, and December 2005. Spatial
distributions of HCHO slant columns from the GEMS algorithm are consistent
with the OMI QA4ECV products, but relatively poorer correlation coefficients
of 0.52–0.76 are found compared to those against the OMHCHO products.
Also, we compare the satellite results with ground-based multi-axis differential optical absorption spectroscopy (MAX-DOAS)
observations. OMI GEMS HCHO vertical columns are 9 %–25 % lower than
those of MAX-DOAS at Haute-Provence Observatory (OHP) in France, Bremen in
Germany, and Xianghe in China. We find that the OMI GEMS retrievals have
less bias than the OMHCHO and OMI QA4ECV products at OHP and Bremen in
comparison with MAX-DOAS.
Tidal variability in the Hong Kong region
Authors: Devlin Adam T. , Pan Jiayi , Lin Hui 
Published: July 2019

Abstract. Mean sea level (MSL) is rising worldwide, and correlated changes in ocean
tides are also occurring. This combination may influence future extreme sea
levels, possibly increasing coastal inundation and nuisance flooding events
in sensitive regions. Analyses of a set of tide gauges in Hong Kong reveal
complex tidal behavior. Most prominent in the results are strong
correlations of MSL variability to tidal variability over the 31-year period
of 1986–2016; these tidal anomaly correlations (TACs) express the
sensitivity of tidal amplitudes and phases (M2, S2, K1,
O1) to MSL fluctuations and are widely observed across the Hong Kong
region. At a few important harbor locations, time series of approximations
of the parameter δ-HAT, computed from combinations of the major
tidal constituents, are found to be highly sensitive to MSL variability,
which may further increase local flood levels under future MSL rise. Other
open-water locations in Hong Kong only show TACs for some individual tidal
constituents but not for combined tidal amplitudes, suggesting that the
dynamics in enclosed harbor areas may be partially frequency dependent and
related to resonance or frictional changes. We also observe positive
correlations of the fluctuations of diurnal (D1) tides to semidiurnal (D2) tides at most locations in the region, which may lead to further
amplified tidal ranges under MSL. It is demonstrated here that tidal changes
in the Hong Kong coastal waters may be important in combination with MSL
rise in impacting future total water levels.
The internal structure and composition of a plate-boundary-scale serpentinite shear zone: the Livingstone Fault, New Zealand

Published: July 2019

Abstract. Deciphering the internal structure and composition of large serpentinite-dominated shear zones will lead to an improved understanding of the rheology of the lithosphere in a range of tectonic settings. The Livingstone Fault in New Zealand is a terrane-bounding structure that separates the basal portions (peridotite; serpentinised peridotite; metagabbros) of the Dun Mountain Ophiolite Belt from the quartzofeldspathic schists of the Caples and Aspiring Terrane. Field and microstructural observations from 11 localities along a strike length of ca. 140 km show that the Livingstone Fault is a steeply dipping, serpentinite-dominated shear zone tens of metres to several hundred metres wide. The bulk shear zone has a pervasive scaly fabric that wraps around fractured and faulted pods of massive serpentinite, rodingite and partially metasomatised quartzofeldspathic schist up to a few tens of metres long. S–C fabrics and lineations in the shear zone consistently indicate a steep east-side-up shear sense, with significant local dispersion in kinematics where the shear zone fabrics wrap around pods. The scaly fabric is dominated (>98 % vol) by fine-grained (≪10 µm) fibrous chrysotile and lizardite–polygonal serpentine, but infrequent (<1 % vol) lenticular relicts of antigorite are also preserved. Dissolution seams and foliation surfaces enriched in magnetite, as well as the widespread growth of fibrous chrysotile in veins and around porphyroclasts, suggest that bulk shear zone deformation involved pressure–solution. Syn-kinematic metasomatic reactions occurred along all boundaries between serpentinite, schist and rodingite, forming multigenerational networks of nephritic tremolite veins that are interpreted to have caused reaction hardening within metasomatised portions of the shear zone. We propose a conceptual model for plate-boundary-scale serpentinite shear zones which involves bulk-distributed deformation by pressure–solution creep, accompanied by a range of physical (e.g. faulting in pods and wall rocks; smearing of magnetite along fault surfaces) or chemical (e.g. metasomatism) processes that result in localised brittle deformation within creeping shear zone segments.
The transition problem in Hungary

Published: July 2019

The curricular background of the transition problem from highschool to universty is analysed in Hungary. While students finish their mathematical studies successfully at highschool, pass their final exams, this knowledge seems to disappear at their first year at university. We investigate the mathematical knowledge expected by the Hungarian universities and compare it to expectations of the National Core Curriculum. Based on the levelling tests of four universities we created a seven problem test for highschool students containing very basic problems required both by the universities and the National Core Curriculum. We analyse the results of the test.

Voorbij de controverse: het Nederlandse neoliberalisme als onderwerp van onderzoek
Authors: Oudenampsen Merijn , Mellink Bram 
Published: July 2019

Beyond the polemic. Dutch neoliberalism as a subject of research.
The word neoliberalism has often been the object of fierce controversy in the Dutch public debate. Prominent intellectuals have equated neoliberalism with extremism and fundamentalism, with some going as far as calling it a ‘totalitarian faith’. The opposite camp in the debate has argued that neoliberalism is largely a self-invented bogeyman of the left, a swearword used by critics to engage in an intellectual witch-hunt. Of course, neoliberalism is not the only social science term suffering from a polemical status. Common concepts such as populism, socialism, nationalism or conservatism have given rise to similar lasting disagreements and comparable accusations of their derogatory use. What does appear to be exceptional about neoliberalism in the Dutch debate, is that very few conceptual and historical studies have been published on the subject. While the word neoliberalism is commonly employed in Dutch mainstream social science, many scholars seem to use the term without much further qualification. This paper explores the controversy and looks for ways to proceed beyond it. Drawing on a recent wave of international scholarship, it outlines an ideational approach to neoliberalism. After tracing the origins of the term neoliberalism, it closes with a preliminary example of an ideational analysis of Dutch neoliberalism.

Klimaatspijbelen heeft wel zin

Published: July 2019

Skipping class for climate?
The most relevant part of a discussion is not what is discussed but what cannot be spoken of. The real taboos are those for which it is taboo to call them taboos. The status quo defines itself as non-ideological while denouncing any challenge to itself as radical. Therefore the column ‘De Blinde Vlek’ frames the framers, politicizes the status quo and articulates what is not heard of.

‘Wij staan op het punt om uit het peloton te demarreren naar de koplopers.’ Interview met Martijn Snoep door redactie Markt & Mededinging, 18 april 2019
Totdat hij in september 2018 voorzitter werd van de ACM, was Martijn Snoep naast advocaat bij De Brauw Blackstone Westbroek ook een van de vaste columnisten van Markt & Mededinging. Van 2013 tot in 2018 liet hij met enige regelmaat zijn licht schijnen over allerhande onderwerpen die het mededingingsrecht en -beleid raken. In verband met zijn benoeming tot voorzitter eindigde Martijn Snoep zijn bijdragen als columnist aan ons blad. Dat leek de redactie van Markt & Mededinging een goede reden om de columns van Martijn Snoep nog eens te herlezen en (mede) aan de hand daarvan hem in zijn nieuwe functie te interviewen over zijn kijk op de ontwikkelingen in het mededingingsrecht en de rol van de ACM.

Online uitbuiting van consumenten voorkomen: een zorgplicht voor dominante ondernemingen?
Online markten vormen een nieuwe uitdaging voor het mededingingsrecht. Alle voordelen van deze vorm van handel in termen van toegankelijkheid en keuzemogelijkheden ten spijt kunnen consumenten hier worden overschaduwd door ondernemingen die in een virtuele omgeving de persoonlijke data van hun tegenpartij kunnen benutten om deze uit te buiten of te discrimineren. Dit artikel behandelt de vraag of, en zo ja wanneer, deze tak van het recht gebruikt kan worden om door middel van het opleggen van een zorgplicht consumenten te beschermen tegen onbillijk ofwel oneerlijk gedrag door partijen die hun digitale machtspositie misbruiken.
Measurements on Stationary Source Emissions and Assessing Impact on Ambient Air Quality around Two Indian Refineries

Published: July 2019

Abstract
Emissions of particulate matter (PM), SO2 and NO2 from stationary sources and their concentration along with benzene and CO in ambient air around two Indian refineries were studied. Prediction of ground level concentration (GLC) of SO2, NO2 and PM was made by dispersion modeling. In Refinery 1, highest SO2 emission (646 mg Nm−3) were detected in Sulphur Recovery Unit while NOx emissions ranged from 57.8 to 445.0 mg Nm−3, respectively from various units. In Refinery 2, highest SO2 emission (935 mg Nm−3) was observed from Utility Boiler while NO2 emissions ranged from 13 to 235 mg Nm−3. Above emissions were within the stipulated emission standards prescribed by Central Pollution Control Board of India. Further, ambient concentrations of the above in the vicinity of these refineries were below their prescribed national ambient air quality standards. Air quality in terms of air quality index (AQI) was moderate or good at the study sites. Dispersion modelling exercise indicated that the observed GLC of SO2 and NO2 could be reasonably predicted by ISC-AERMOD model for both refineries while there was moderate to substantial difference between observed and modeled PM values due to presence of several sources of particulate emissions in the region that could not be considered in the model.

Abstract
In this study, we investigate the meteorological characteristics and the effect of local emissions during high PM10 concentrations in the Seoul Metropolitan Area (SMA) by utilizing data from a high-resolution urban meteorological observation system network (UMS-Seoul) and The Air Pollution Model (TAPM). For a detailed analysis, days with PM10 concentrations higher than 80 μg m−3 for daily average PM10 concentration (classified as unhealthy by the Korean Ministry of Environment) in the Seoul Metropolitan Area (SMA) were classified into 3 Cases. Case I was defined as when the prevailing effect was from outside the SMA. Case II was defined as when the prevailing effect was a local effect with outside. Case III was defined as when the prevailing effect was local. Overall, high PM10 concentrations in the SMA mostly occurred under weak migratory anticyclone systems over the Korean Peninsula during warm temperatures. Prior to the PM10 concentration reaching the peak concentration, the pattern in each case was distinctive. After peak concentrations, however, the pattern for the 3 cases became less distinct. This study showed that nearly 50% of the high PM10 concentrations in the SMA occurred in spring and were governed by the conditions for Case II more than these for Cases I and III. In spring, the main sources of the high PM10 concentrations in the SMA were local emissions due to the predominance of weak winds and local circulation. The simulation showed that the non-SMA emissions were about 63 to 73% contribution to the spring high PM10 concentrations in the SMA. Specifically, local point sources including industrial combustion, electric utility, incineration and cement production facilities scattered around the SMA and could account for PM10 concentrations more than 10μg m−3 in the SMA.
Propagation of Shock Waves in Two Rooms Communicating through an Opening
Authors: Sochet Isabelle , Gault Kevin , Hakenholz Luc 
Published: July 2019

Confined explosions represent a serious safety hazard as significant damage to humans and structures is observed, unlike in free-field explosions. An experimental small-scale study investigated the blast wave in a single-story building. The blast waves were generated by the detonation of a gaseous charge. The building was divided into two rooms by a movable wall which could be positioned at three different locations. The presence of an opening in this movable wall means that two rooms were considered: a transmitter room (TR) and a receptor room (RR). The configuration without the movable wall was also studied. Pressure profiles recorded with pressure gauges at ground level and on the wall presented numerous reflections. The damage effects were severe since the maximum overpressure never fell below 0.2 bar. Although this study is limited to a small scale and gaseous detonation charge, the results can be applied to a large scale and for a TNT charge.
Récits d’expériences de jeunes issus de l’immigration en situation de décrochage : quand l’école « ne marche pas » ou est un bad trip

Published: July 2019

Les résultats de recherche présentés dans cet article portent sur l’expérience socioscolaire de quatre jeunes en situation de décrochage scolaire. Ces jeunes sont d’origine haïtienne et sont inscrits dans des écoles de milieux défavorisés. Des entretiens biographiques ont documenté leur cheminement scolaire depuis la maternelle.Pour analyser ce cheminement, nous nous appuyons sur la perspective du rapport à l’école et aux savoirs scolaires. Celle-ci met en exergue le rôle de l’élève acteur tout en permettant de considérer le poids des contextes et des facteurs systémiques.La recherche montre la présence de difficultés scolaires dès le primaire chez les jeunes qui font qu’ils se démobilisent peu à peu dans les apprentissages. Elle montre également une mobilisation familiale freinée par un cumul de vulnérabilités sociales ainsi qu’un réseau de pairs expérimentant la même problématique du décrochage. Le rapport à l’école et aux savoirs est marqué du sceau de l’ennui, du non-sens et du désengagement.Une réflexion est menée sur les défis, inhérents aux cadres de référence et méthodologiques mobilisés, pour recueillir la parole de ces jeunes et rendre compte de la complexité de leur expérience, compte tenu de leur rapport douloureux à l’école et aux apprentissages scolaires.
Récits d’élèves du secondaire s’inscrivant dans un processus de résilience scolaire
Authors: Nadeau Sandy , Lessard Anne 
Published: July 2019

Maintes études ont permis de mettre en évidence de multiples facteurs augmentant le risque que l’élève abandonne ses études avant l’obtention du diplôme d’études secondaires (Fortin, Marcotte, Diallo, Potvin et Royer, 2013). Par contre, certains élèves pourtant exposés à ces facteurs obtiennent leur diplôme (Harvey, 2007). Il apparaît ainsi pertinent de se pencher sur les expériences ayant joué un rôle de prévention du décrochage scolaire. L’objectif de cette étude est de comprendre, à partir des processus interactionnels du milieu familial et de la classe, l’expérience d’élèves du secondaire s’inscrivant dans un processus de résilience scolaire. Un devis descriptif qualitatif est utilisé. Des entretiens semi-dirigés ont été menés auprès de 18 élèves s’étant adaptés positivement au cours de la première année du secondaire. Le compte rendu intégral a fait l’objet d’une analyse thématique et d’une construction de récits narratifs. Six processus interactionnels émergeant du discours des participants sont mis en récits. Bien que le discours de plusieurs élèves laisse paraître le fait que les processus interactionnels du milieu familial et de la classe favorisent leur adaptation positive, il semble que l’adaptation de certains soit plutôt due à leur volonté d’atteindre un objectif qu’ils ont eux-mêmes établi.
D’étudiant à « élève du son »
Authors: Boudreault-Fournier Alexandrine 
Published: July 2019

Cet article traite d’une approche pédagogique de l’enseignement du son selon une perspective anthropologique en prenant comme étude de cas le cours de premier cycle « Anthropologie du son » offert au département d’anthropologie de l’Université de Victoria depuis 2012, cours qui constitue, à notre connaissance, une première dans une université canadienne. L’article traite de la transformation d’étudiants en « élèves du son » grâce à l’« éveil sonore », qui résulte de l’attention particulière portée aux sons qui nous entourent. De plus, l’enseignement du son, tout comme les approches sensorielles en anthropologie, contribue à la déstabilisation de l’hégémonie du visuel souvent observée dans plusieurs sociétés modernes. L’anthropologie devrait s’intéresser davantage aux phénomènes sonores dans l’enseignement et lors des terrains ethnographiques. Une telle ouverture aurait pour avantage de stimuler de nouvelles manières d’analyser, de théoriser et de créer en anthropologie.
