Abstract. The two concerted
field campaigns, Arctic CLoud Observations Using airborne measurements during
polar Day (ACLOUD) and the Physical feedbacks of Arctic planetary boundary
level Sea ice, Cloud and AerosoL (PASCAL), took place near Svalbard from
23 May to 26 June 2017. They were focused on studying Arctic mixed-phase
clouds and involved observations from two airplanes (ACLOUD), an icebreaker
(PASCAL) and a tethered balloon, as well as ground-based stations. Here, we
present the synoptic development during the 35-day period of the campaigns,
using near-surface and upper-air meteorological observations, as well as
operational satellite, analysis, and reanalysis data. Over the campaign
period, short-term synoptic variability was substantial, dominating over the
seasonal cycle. During the first campaign week, cold and dry Arctic air from
the north persisted, with a distinct but seasonally unusual cold air
outbreak. Cloudy conditions with mostly low-level clouds prevailed. The
subsequent 2 weeks were characterized by warm and moist maritime air from
the south and east, which included two events of warm air advection. These
synoptical disturbances caused lower cloud cover fractions and
higher-reaching cloud systems. In the final 2 weeks, adiabatically warmed
air from the west dominated, with cloud properties strongly varying within the range of the two other periods. Results presented here provide
synoptic information needed to analyze and interpret data of upcoming studies
from ACLOUD/PASCAL, while also offering unprecedented measurements in a
sparsely observed region.

Published: December 2018

Abstract. Aerosols that serve as ice nucleating particles (INPs) have the potential to
modulate cloud microphysical properties and can therefore impact cloud
radiative forcing (CRF) and precipitation formation processes. In remote
regions such as the Arctic, aerosol–cloud interactions are severely
understudied yet may have significant implications for the surface energy
budget and its impact on sea ice and snow surfaces. Further, uncertainties in
model representations of heterogeneous ice nucleation are a significant
hindrance to simulating Arctic mixed-phase cloud processes. We present
results from a campaign called INPOP (Ice Nucleating Particles at Oliktok
Point), which took place at a US Department of Energy Atmospheric Radiation
Measurement (DOE ARM) facility in the northern Alaskan Arctic. Three time-
and size-resolved aerosol impactors were deployed from 1 March to 31 May 2017
for offline ice nucleation and chemical analyses and were co-located with
routine measurements of aerosol number and size. The largest particles (i.e.,
≥ 3 µm or “coarse mode”) were the most efficient INPs by
inducing freezing at the warmest temperatures. During periods with snow- and
ice-covered surfaces, coarse mode INP concentrations were very low (maximum
of 6 × 10−4 L−1 at −15 ∘C), but higher
concentrations of warm-temperature INPs were observed during late May
(maximum of 2 × 10−2 L−1 at −15 ∘C). These
higher concentrations were attributed to air masses originating from over
open Arctic Ocean water and tundra surfaces. To our knowledge, these results
represent the first INP characterization measurements in an Arctic oilfield
location and demonstrate strong influences from mineral and marine sources
despite the relatively high springtime pollution levels. Ultimately, these
results can be used to evaluate the anthropogenic and natural influences on
aerosol composition and Arctic cloud properties.
Deglacial to postglacial history of Nares Strait, Northwest Greenland: a marine perspective from Kane Basin
Authors: Georgiadis Eleanor , Giraudeau Jacques , Martinez Philippe , Lajeunesse Patrick , St-Onge Guillaume , Schmidt Sabine , Massé Guillaume 
Published: December 2018

Abstract. A radiocarbon-dated marine sediment core retrieved in Kane Basin, central
Nares Strait, was analysed to constrain the timing of the postglacial opening
of this Arctic gateway and its Holocene evolution. This study is based on a
set of sedimentological and geochemical proxies of changing sedimentary
processes and sources that provide new insight into the evolution of ice
sheet configuration in Nares Strait. Proglacial marine sedimentation at the
core site initiated ca. 9.0 cal ka BP following the retreat of
grounded ice. Varying contributions of sand and clasts suggest unstable sea
ice conditions and glacial activity, which subsisted until ca. 7.5 cal ka BP under the combined influence of warm atmospheric temperatures and
proglacial cooling induced by the nearby Innuitian (IIS) and Greenland (GIS)
ice sheets. An interval rich in ice-rafted debris (IRD) is interpreted as the collapse of the ice
saddle in Kennedy Channel ca. 8.3 cal ka BP that marks the complete
opening of Nares Strait and the initial connection between the Lincoln Sea
and northernmost Baffin Bay. Delivery of sediment by icebergs was
strengthened between ca. 8.3 and ca. 7.5 cal ka BP
following the collapse of the buttress of glacial ice in Kennedy Channel that
triggered the acceleration of GIS and IIS fluxes toward Nares Strait. The
destabilisation in glacial ice eventually led to the rapid retreat of the GIS
in eastern Kane Basin at about 8.1 cal ka BP as evidenced by a noticeable
change in sediment geochemistry in our core. The gradual decrease in
carbonate inputs to Kane Basin between ∼8.1 and
∼4.1 cal ka BP reflects the late deglaciation of Washington
Land. The shoaling of Kane Basin can be observed in our record by the
increased winnowing of lighter particles as the glacio-isostatic rebound
brought the seabed closer to subsurface currents. Reduced iceberg delivery
from 7.5 to 1.9 cal ka BP inferred by our dataset may be linked to the
retreat of the bordering ice sheets on land that decreased their number of
marine termini.
A database of water and heat observations over grassland in the north-east of Japan
Authors: Ma Wenchao , Asanuma Jun , Xu Jianqing , Onda Yuichi 
Published: December 2018

Abstract. A highly valuable database of long-term hydrometeorological measurements is
presented, containing in situ observations for a period of 37 years from a
well-maintained grassland in the north-east of Japan. The observations
include shortwave radiation, net radiation, air and dew point temperatures at
three elevations, soil temperature at four depths, sensible heat flux, soil
heat flux, wind speed, relative humidity, air pressure and precipitation. The
heights of measurements are 1.6, 12.5 and 29.5 m above ground, with the
soil-layer observations at depths of 0.02, 0.1, 0.5 and 1 m. This
high-quality database includes four temporal resolutions of 10 s, 0.5 h,
1 h and 24 h, with the hourly data
presented here. Monthly and annual statistics are presented at the database
web page of the Center for Research in Isotopes and Environmental Dynamics
and Prediction of the University of Tsukuba,
http://doi.org/10.24575/0001.198108. We validated the data by comparing
them with published data from the local meteorological agency in Tateno operated
by the Japan Metrological Agency, including the average, maximum and minimum
values of air temperature, shortwave radiation, wind speed, relative
humidity and precipitation. We have generated a daily downward longwave
radiation time series with a method developed by Kondo and Xu (1997) based on
the observations from the database. This constructed time series agrees well
with observations collected between 2002 and 2006, as evaluated based on the
values of the Nash–Sutcliffe efficiency (=0.947) and percent bias (=1.486). For the whole database, annually averaged values show a positive
trend in precipitation, air temperature, shortwave radiation, net radiation
and sensible heat flux over the past 37 years, with a negative trend detected
for wind speed, soil heat flux and soil temperature.

Abstract. Temporal series maps of irrigated areas, and the
corresponding irrigation water requirements based on remote sensing, is a
recognized tool contributing to water governance at different scales, from
water user associations to whole river basin districts. These thematic
cartographies offer a first estimation of the crop irrigation requirements,
and a biophysical based approach of the temporal and spatial distribution of
the crop water use in the cultivated areas. This work describes the
operational application of these methodologies, providing valuable
information for water governance and management purposes. The basic products
obtained in the whole Spanish part of the Iberian Peninsula during the
period 2014–2017 were: (i) annual maps of irrigated crops based on time
series of multispectral satellite imagery; and (ii) the direct remote
sensing-based water accounting, by quantifying agricultural water flows
(e.g. rainfall, irrigation, evapotranspiration, drainage and recharge),
through a remote sensing-based soil water balance. Hence this paper provides
a remote sensing based water accounting approach, which relies on dense time
series of multispectral imagery acquired by the multisensor constellation
arranged by Landsat 8 and Sentinel-2 satellites, jointly with meteorological
data and agronomic knowledge. Then, based on these purpose and approach,
annual and monthly maps of net irrigation water requirements have been
elaborated at the most practical spatial and temporal scales for water
governance purposes over big areas such river basin districts. This work
summarizes the methodologies used and discuss the technical and
non-technical feasibility of the proposed approach.
Remote sensing vegetation index methods to evaluate changes in greenness and evapotranspiration in riparian vegetation in response to the Minute 319 environmental pulse flow to Mexico
Authors: Nagler Pamela L. , Jarchow Christopher J. , Glenn Edward P. 
Published: December 2018

Abstract. During the spring of 2014, 130 million m3 of water were
released from the United States' Morelos Dam on the lower Colorado River to
Mexico, allowing water to reach the Gulf of California for the first time in
13 years. Our study assessed the effects of water transfer or ecological
environmental flows from one nation to another, using remote sensing.
Spatial applications for water resource evaluation are important for
binational, integrated water resources management and planning for the
Colorado River, which includes seven basin states in the US plus two
states in Mexico. Our study examined the effects of the historic binational
experiment (the Minute 319 agreement) on vegetative response along the
riparian corridor. We used 250 m Moderate Resolution Imaging
Spectroradiometer (MODIS), Enhanced Vegetation Index (EVI) and 30 m Landsat 8 satellite imagery to track
evapotranspiration (ET) and the normalized difference vegetation index
(NDVI). Our analysis showed an overall increase in NDVI and
evapotranspiration (ET) in the year following the 2014 pulse, which reversed
a decline in those metrics since the last major flood in 2000. NDVI and ET
levels decreased in 2015, but were still significantly higher (P < 0.001) than pre-pulse (2013) levels. Preliminary findings show that the
decline in 2015 persisted into 2016 and 2017. We continue to analyse results
for 2018 in comparison to short-term (2013–2018) and long-term (2000–2018)
trends. Our results support the conclusion that these environmental flows
from the US to Mexico via the Minute 319 “pulse” had a positive, but
short-lived (1 year), impact on vegetation growth in the delta.
Markers of Agency in Preservice Music Teachers: A Directed Content Analysis of Written Coursework
Authors: Rathgeber Jesse , Mantie Roger 
Published: December 2018

Abstract
The purpose of this study was to examine agentic thinking among preservice music teachers through a “directed content analysis” (Hsieh & Shannon, 2005) of the written coursework of 2 cohorts of preservice music teachers (N = 66) enrolled in an introduction to music education course in order to advance knowledge of agentic thinking in music teacher education research and practice. We used a theoretical framework informed by Emirbayer and Mische’s (1998) triadic conception of agency that positions human agency at the nexus of 3 temporally oriented elements: iteration (past), projectivity (future), and practical evaluation (present). We investigated the agentic temporalities of different assignment types and analyzed the agentic vocabulary usage in premidterm and postmidterm assignments by cohort, identified gender, year in school, residency status, major, and applied instrument. We found slight differences in overall agentic vocabulary and vocabulary by agentic element between cohorts. Unexpectedly, we noted a marked decline in overall agentic vocabulary usage in postmidterm written assignments compared to premidterm written assignments. Analysis of change over time by agentic element found decreases in iterative and practical evaluative vocabulary and an increase in projective vocabulary usage in postmidterm written assignments. Findings from key-word-in-context analysis, however, suggest that a decline in agentic vocabulary may be related to a refinement in agentic vocabulary usage and an increased openness to different perspectives and career options. Based on our results, we argue that Emirbayer and Mische’s framework may provide music teacher educators and researchers with a nuanced tool by which to investigate, understand, and foster music teacher agency.
De twitterende wijkagent, veiligheidsbeleving en het beeld van de politie

Twitter, perceptions of safety and police image
This article reports briefly on research into the relationship between Twitter use by community police officers and citizens’ perceived safety. To this end, multiple relevant determinants of safety perceptions were included in the study: assessment of objective safety, perceptions of quality of life and social capital, risk perception and opinion on the police. The use of Twitter proved to have a modest, yet significant impact: followers on Twitter report a lower assessment of objective safety and a more positive opinion on the police. No direct, significant relation was found between the use of Twitter by the neighbourhood police officer and citizens’ perceived safety.

It could have been your daughter
Three cases of sexual violence with two teenagers and one young woman as dead victims have put – besides the indescribable sufferings of themselves, their families, friends and acquaintances – a heavy burden on Dutch collective memories of the year 2017. Dutch society commiserated on a massive scale: volunteers helped searching, thousands united in silent marches and more than 400 thousand citizens signed an online petition that emotionally called for a firm revision of the ‘failing justice system’. In this article we explore the deeper social, personal and cultural elements that gave media messages their strong emotional impact in Dutch society.
Terugkoppeling door de rechter, wat moet de wetgever daarvan vinden?

Terugkoppeling door de rechter, wat moet de wetgever daarvan vinden?
In deze bijdrage staat centraal wat de terugkoppeling van de rechter aan de wetgever vraagt van de wetgever. Allereerst wordt geconcludeerd dat ook zonder expliciete terugkoppeling de rechter zich wendt tot de wetgever en dat een expliciete terugkoppeling als zodanig geen verandering in de verhouding tussen rechter en wetgever met zich brengt. Er lijken echter wel tekenen te zijn dat de verhouding tussen rechtspraak en wetgever in beweging is. Daar hoeft de wetgever niet bij te staan kijken. Hij kan door een actieve houding de beweging beïnvloeden. Verschillende mogelijkheden die de wetgever heeft om met inachtneming van de staatsrechtelijke verhoudingen te reageren op rechtspraak en het belang van het tijdig maken van duidelijke keuzes in maatschappelijk gevoelige kwesties door de wetgever zelf, passeren de revue. Ten slotte wordt een oproep gedaan om met elkaar in gesprek te gaan over de kwaliteit van de wetgeving, de betekenis van de jurisprudentie, de overlap tussen politieke afwegingen en rechtsvinding en over de vraag waar de grenzen nu precies liggen.

Is terugkoppeling naar de wetgever een taak van de bestuursrechter? Ja, maar op het juiste moment en op transparante wijze
In welke mate moet de rechter – meer in het bijzonder de Centrale Raad van Beroep (CRvB) – zijn ervaringen met wetgeving rechtstreeks terugkoppelen naar de wetgever? Bij ervaringen valt te denken aan geconstateerde leemtes of tegenstrijdigheden in wet- en regelgeving, aan strijd met hoger recht, aan problemen met overgangsrecht, of meer fundamenteel, aan de gevolgen van (grote) wetgevingsoperaties zoals de ‘decentralisaties’ in het sociaal domein.

Conflict management as an added value in care organisations: a practical story
The hospital sector is not only confronted with the challenges of technical and digital medicine (AI), but also with the expectations of increasingly more talkative patients and their relatives. Luc Van Bauwel introduces you to and testifies about the way in which the ombudsman service of an important hospital group in Antwerp evolved from mere complaint handling as an ombudsservice on the basis of principles of mediation to anchoring the ideas in the liars of management, doctors and other employees; he gives an overview of how the professional ombudsman organized his self and how the surrounding other stakeholders perceived this relatively new ‘ombudsman’ service, which was established by law; how patients have experienced this form of conflict management in the past 15 years, which has been monitored inside the care institution twice in the last 15 years; in the end, he testifies how the acquired/gained trust has grown, as a result of which he now participates on board level in an active role from the very beginning of developing and implementing changes, in the ever-present processes of change, in particular aimed at the doctors associated with the organization.
Effect of Seasonal Variation on the Levels and Behaviours of Formaldehyde in the Atmosphere of a Suburban Area in Cairo, Egypt

Published: December 2018

Abstract
Formaldehyde (HCHO) is a carcinogenic pollutant, has an active role in tropospheric photochemistry, and can be affected by seasonal variations. To our knowledge, this is the first comprehensive study of the effect of seasonal variation on the levels and behaviours of HCHO in the atmosphere of a suburban area (15 May City) in Cairo. Daytime and nighttime measurements of HCHO were performed from March 2014 to February 2015. The highest average daily concentrations of HCHO were found in summer and the lowest in winter. The difference was statistically significant (p≤0.001). Daily average HCHO concentrations in spring, summer, autumn and winter were higher than the corresponding values in many polluted cities in the world. This was true for both weekdays and weekends. HCHO was higher in daytime than nighttime on weekdays and weekends, and the differences in mean concentrations were statistically significant (p ≤0.001), except during the autumn and winter on weekends. Therefore, the contribution of photochemical reactions in the observed levels of HCHO might be greater than that of traffic emissions. This was further proved by the significant positive correlation found between daytime HCHO concentrations and temperature. HCHO concentrations were higher on weekdays than weekends, the differences in mean concentrations were statistically significant (p≤0.001). This may be attributed to higher emission of HCHO from higher traffic intensity during daytime. Significant positive correlations (p≤0.001) were found between daytime and nighttime HCHO concentrations, both on weekdays and weekends suggesting that HCHO comes from the same sources.
High-Performance Liquid Chromatography (HPLC) as a Tool for Standardization of Complex Herbal Drugs
Authors: Govindarajan Raghavan , Tejas Vyas , Pushpangadan Palpu 
Published: December 2018

Abstract
Background: Herbal formulations have reached tremendous acceptability as therapeutic agents for several diseases mainly due to the indiscriminate use of modern medicine such as antibiotics, steroids and other synthetic drugs. The increasing popularity in plant-based drugs is leading to a fast growing market for plant-based drugs pharmaceuticals, nutraceuticals, functional foods, and even cosmeceuticals. Objective: The development of authentic analytical methods for complex herbal drugs, especially poly herbal formulations which can reliably profile the phytochemical composition, including quantitative analyses of marker/bioactive compounds and other major constituents, is a major challenge to scientists. Standardization is an important step for the establishment of a consistent biological activity, a consistent chemical profile, or simply a quality assurance program for production and manufacturing of herbal drugs. Methods/Results: HPLC as a tool has been widely used in the standardization of complex herbal drugs because of its ability to estimate the presence of active (chemical or biological) markers both qualitatively and quantitatively. Conclusions: An overview of various HPLC techniques that can be used for standardization of herbal drugs has been presented.
