Abstract. The study assesses the possible benefit of assimilating aerosol optical depth
(AOD) from the future space-borne sensor FCI (Flexible Combined Imager) for
air quality monitoring in Europe. An observing system simulation experiment
(OSSE) was designed and applied over a 4-month period, which includes a severe-pollution episode. The study focuses on the FCI channel centred at 444 nm,
which is the shortest wavelength of FCI. A nature run (NR) and four different
control runs of the MOCAGE chemistry transport model were designed and
evaluated to guarantee the robustness of the OSSE results. The synthetic AOD
observations from the NR were disturbed by errors that are typical of the
FCI. The variance of the FCI AOD at 444 nm was deduced from a global
sensitivity analysis that took into account the aerosol type, surface
reflectance and different atmospheric optical properties. The experiments
show a general benefit to all statistical indicators of the assimilation of
the FCI AOD at 444 nm for aerosol concentrations at the surface over Europe, and
also a positive impact during the severe-pollution event. The simulations
with data assimilation reproduced spatial and temporal patterns of PM10
concentrations at the surface better than those without assimilation all along the
simulations and especially during the pollution event. The advantage of
assimilating AODs from a geostationary platform over a low Earth orbit
satellite has also been quantified. This work demonstrates the capability of
data from the future FCI sensor to bring added value to the MOCAGE aerosol
simulations, and in general, to other chemistry transport models.
How much solar wind data are sufficient for accurate fluxgate magnetometer offset determinations?
Authors: Plaschke Ferdinand
Published: March 2019

Abstract. Accurate magnetic field measurements by fluxgate magnetometers on-board spacecraft require ground and regular in-flight calibrations activities. Therewith, the parameters of a coupling matrix and an offset vector are adjusted; they are needed to transform raw magnetometer outputs into calibrated magnetic field measurements. The components of the offset vector are typically determined by analyzing Alfvénic fluctuations in the solar wind, if solar wind measurements are available. These are characterized by changes in the field components, while the magnetic field modulus stays constant. In this paper, the following question is answered: How much solar wind data are sufficient for accurate fluxgate magnetometer offset determinations? It is found that approximately 50 hours of solar wind data are sufficient to achieve offset accuracies of 0.2 nT, and about 20 hours suffice for accuracies of 0.3 nT or better, if the magnetometer offsets do not drift within these time intervals and if the spacecraft fields do not vary at the sensor position. Offset determinations with uncertainties lower than 0.1 nT, however, would require at least hundreds of hours of solar wind data.
Dew frequency across the US from a network of in situ radiometers
Authors: Ritter François , Berkelhammer Max , Beysens Daniel
Published: March 2019

Abstract. Dew formation is a ubiquitous process, but its importance to energy budgets or
ecosystem health is difficult to constrain. This uncertainty arises largely
because of a lack of continuous quantitative measurements on dew across
ecosystems with varying climate states and surface characteristics. This
study analyzes dew frequency from the National Ecological Observatory Network
(NEON), which includes 11 grasslands and 19 forest sites from 2015 to 2017.
Dew formation is determined at 30 min intervals using in situ radiometric
surface temperatures from multiple heights within the canopy along with
meteorological measurements. Dew frequency in the grasslands ranges from
15 % to 95 % of the nights with a strong linear
dependency on the nighttime relative humidity (RH), while dew frequency in
the forests is less frequent and more homogeneous (25±14 %, 1
standard deviation – SD). Dew mostly forms at the top of the canopy for the
grasslands due to more effective radiative cooling and within the canopy for the
forests because of higher within the canopy RH. The high temporal resolution of
our data showed that dew duration reaches maximum values
(∼6–15 h) for RH∼96 % and for a
wind speed of ∼0.5ms-1, independent of the ecosystem type.
While dew duration can be inferred from the observations, dew yield needs to
be estimated based on the Monin–Obukhov similarity theory. We find yields of
0.14±0.12mmnight-1 (1 SD from nine grasslands) similar to
previous studies, and dew yield and duration are related by a quadratic
relationship. The latent heat flux released by dew formation is estimated to
be non-negligible (∼10Wm-2), associated with a Bowen ratio
of ∼3. The radiometers used here provide canopy-averaged surface
temperatures, which may underestimate dew frequency because of localized cold
points in the canopy that fall below the dew point. A statistical model is
used to test this effect and shows that dew frequency can increase by an
additional ∼5 % for both ecosystems by considering a reasonable
distribution around the mean canopy temperature. The mean dew duration is
almost unaffected by this sensitivity analysis. In situ radiometric surface
temperatures provide a continuous, non-invasive and robust tool for studying
dew frequency and duration on a fine temporal scale.
MAPPING SPATIAL ACCURACY OF FOREST TYPE CLASSIFICATION IN JAXA’s HIGH-RESOLUTION LAND USE AND LAND COVER MAP

Published: March 2019

Abstract. Accuracy assessment of forest type maps is essential to evaluate the classification of forest ecosystems quantitatively. However, map users do not understand in which regions those forest types are well classified from conventional static accuracy measures. Hence, the objective of this study is to unveil spatial heterogeneities of accuracies of forest type classification in a map. Four forest types (deciduous broadleaf forest (DBF), deciduous needleleaf forest (DNF), evergreen broadleaf forest (EBF), and evergreen needleleaf forest (ENF)) found in the JAXA’s land use / cover map of Japan were assessed by a volunteered Site-based dataset for Assessment of Changing LAnd cover by JAXA (SACLAJ). A geographically weighted (GW) correspondence matrix was applied to them to calculate the degree of overall agreements of forest type classes (forest overall accuracy), and the degree of accuracy for each forest class (forest user’s and producer’s accuracies) in a spatially varying way. This study compared spatial surfaces of these measures with static ones of them. The results show that the forest overall accuracy of the forest map tends to be relatively more accurate in the central Japan, while less in the Kansai and Chubu regions and the northern edge of Hokkaido. Static forest user’s accuracy measures for DBF, DNF, and ENF are better than forest producer’s accuracy ones, while the GW approach tells us such characteristics vary spatially and some areas have opposite trends. This kind of spatial accuracy assessment provides a more informative description of the accuracy than the simple use of conventional accuracy measures.
DEVELOPMENT OF METHODOLOGY FOR PLANT PHENOLOGY MONITORING BY GROUND-BASED OBSERVATION USING DIGITAL CAMERA
Authors: Yamashita M. , Shinomiya Y. , Yoshimura M.
Published: March 2019

Abstract. When monitoring phenology at ground level, it would be more important to continue observations in long terms and to detect the timing of various phenological events such as leafing, flowering and autumn senescence. In this study, to develop the methodology for plant phenology monitoring by using digital camera, we examined how multiple image indices, which are derived from multi-temporal visible images, respond to the changes of colors of leaves and flowers for several target species of plants, and tried to detect various phenology events by tracing time series changes of the coordinate in the feature spaces of two indices. As a result, we found out that it was possible to understand the characteristics of the phenological events for different species from each image index. Also, it was identified that the utility of combination with two indices would be effective to detect the timing of phenology events in the feature space of two indices. In the actual phenology monitoring, it would be effective to use a single index for understanding the seasonal characteristics and to use the combination of two indices for detection of the timing of phenology events by tracing the time series changes in the feature space.

Abstract. Oceanic emissions of the climate relevant trace gases carbonyl sulfide (OCS) and carbon disulfide (CS2) are a major source to their atmospheric budget. Their current and future emission estimates are still uncertain due to incomplete process understanding and, therefore, inexact quantification across different biogeochemical regimes. Here we present the first concurrent measurements of both gases together with related fractions of the dissolved organic matter (DOM) pool, i.e. solid-phase extractable dissolved organic sulfur (DOSSPE), chromophoric (CDOM) and fluorescent dissolved organic matter (FDOM) from the Eastern Tropical South Pacific (ETSP). These observations are used to estimate in-situ production rates and identify their drivers. We find different limiting factors of marine photoproduction: while OCS production is limited by the humic-like DOM fraction that can act as a photosensitizer, high CS2 production coincides with high DOSSPE concentration. The lack of correlation between OCS production and DOSSPE may be explained by the active cycling of sulfur between OCS and dissolved inorganic sulfide via OCS photoproduction and hydrolysis. In addition, the only existing parameterization for OCS dark production is validated and updated with new rates from the ETSP and the Indian Ocean. Our results will help to predict oceanic concentrations and emissions of both gases on regional and, potentially, global scales.
Single super-vortex as a proxy for ocean surface flow fields
Authors: Jánosi Imre M. , Vincze Miklós , Tóth Gábor , Gallas Jason A. C.
Published: March 2019

Abstract. Empirical flow field data evaluation in a well studied ocean region along the U.S. West Coast revealed a surprisingly strong relationship between the surface integrals of kinetic energy and enstrophy (squared vorticity). This relationship defines a single isolated Gaussian super-vortex, whose fitted size parameter is related to the mean eddy size, and the square of the fitted height parameter is proportional to the sum of the square of all individual eddy amplitudes obtained by standard vortex census. This finding allows a very effective coarse-grained eddy statistics with minimal computational efforts. As an illustrative example, the westward drift velocity of eddies is determined from a simple cross correlation analysis of kinetic energy integrals.
Crustal-scale depth imaging via joint FWI of OBS data and PSDM of MCS data: a case study from the eastern Nankai Trough
Authors: Górszczyk Andrzej , Operto Stephane , Schenini Laure , Yamada Yasuhiro
Published: March 2019

Abstract. Imaging via Pre-Stack Depth Migration (PSDM) from reflection towed-streamer Multi-Channel Seismic (MCS) data at the scale of the whole crust is inherently difficult. This mainly results because the depth-penetration of the seismic wavefield is controlled, firstly (i) by the acquisition design, like streamer length and air-gun source configuration, and secondly (ii) by the complexity of the crustal structure. Indeed, the limited length of the streamer makes the estimation of velocities from deep targets challenging due to the velocity-depth ambiguity. The problem is even more pronounced when processing 2D seismic data, due to the lack of multi-azimuthal coverage. Therefore, in order to broaden our knowledge about the deep crust using seismic methods, one shall target the development of specific imaging workflows integrating different seismic data. Here we propose the combination of velocity model-building using (i) first-arrival traveltime tomography (FAT) and full-waveform inversion (FWI) of wide-angle/long-offset data collected by stationary Ocean Bottom Seismometers (OBS) and (ii) PSDM of short-spread towed-streamer MCS data for reflectivity imaging, using the former velocity model as background model. We present an application of such workflow to seismic data collected by Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and Institut Français de Recherche pour l’Exploitation de la Mer (IFREMER) in the eastern Nankai Trough (Tokai area) during the 2000/2001 SFJ experiment. We show that the FWI model, although derived from OBS data, provides yet an acceptable background velocity field for the PSDM of the MCS data. Furthermore, from the initial PSDM, we first refine the FWI background velocity model by minimizing the residual moveouts (RMO) picked in the prestack migrated volume through slope tomography (ST), from which we generate a better focused migrated image. Such integration of different seismic data sets and leading-edge imaging techniques led to optimal imaging results at different resolution levels. That is, the large-to-intermediate scale crustal units identified in the high-resolution FWI velocity model extensively complement the short-scale reflectivity inferred from the MCS data to better constrain the structural factors controlling the geodynamics of the Nankai Trough area.
Degree of Observance of Ease of Doing Business and Efficient Government Service Delivery Act in the Department of Education in Nueva Ecija in the Philippines

Published: March 2019

Implementation of laws intended to prevent commission of negative bureaucratic behavior is a challenge to most government agencies. Republic Act No. 11032, otherwise known as Ease of Doing Business and Efficient Government Service Delivery Act of 2018, aims to strengthen the Anti-Red Tape Act (ARTA) of 2007 that lessens the perennial problem of bureaucratic red tape which causes graft and corruption. This study aims to determine the degree of observance on the three core components of ARTA namely citizen’s charter, access to government service through frontline services, and report card survey. In addition, zero-contact policy is also observed which is an amendment to the existing law. Based on the results, the core components of Republic Act No. 11032 are always observed in the Department of Education Division of Nueva Ecija but the presence of queuing is observed regardless of the institution’s effort to eliminate red tapes. The success of policy implementation can be fully achieved when coupled with a change of behavior on both part of the service providers and public clientele. Bureaucratic equity followed by inculcation of core values by the service providers with the embodiment of the norms of conduct and ethical standards contribute in the delivery of an efficient government service.
Creating a Playable Academic Edition of Mourning Dove’s Cogewea or How Games can Decolonize
Authors: Humphreys Sara
Published: February 2019

Digital games have the tools and capacity to build interactive worlds that can both share knowledge and decolonize. Even though games have been accused of reinforcing white supremacist systems that tend to privilege profit over humanity, digital games by Indigenous and Indigenist artists and scholars provide evidence that games have the tools to facilitate decolonization. Along these lines, this paper is an exploration of how digital games can help to decolonize and reframe how Indigenous literature is read in the postsecondary classroom, specifically academic editions of Indigenous literatures.

Published: March 2019

Aims: A bibliometric analysis identifies the major publications that influence the clinical management of Hepatocellular Carcinoma (HCC). Within this study, the 100 most cited HCC articles are noted and analysed.

Methods: The search terminology “Hepatocellular carcinoma” and “HCC” were used to search through the Thomson Reuters Web of Science database. The inclusion criteria consisted of English language full articles. The subject matter, author and institution details, year of publication and journal were recorded for the 100 most cited HCC articles. Citation rate index was calculated by dividing the number of citations by the number of years since publication.

Results: The search through the Thomson Reuters Web of Science database identified 39,518 eligible papers. The median (range) citation number was 909 (4419 to 458). The most cited article (produced by Llovet et al) discussed the role of Sorafenib in advanced HCC (4419 citations). Hepatology published the most articles (n=20, 20,533 citations), however the Lancet had the overall highest citation number of 39219, across 9 published articles. The most discussed topic was HCC management (n=31), followed by prognosis (n=18) and aetiology (n=15).

Conclusion: This bibliometric analysis has identified the 100 most cited HCC articles. Through integrating new knowledge into clinical practice, this has enabled novel treatment strategies to be utilised for patients with HCC. This study highlights what makes a citable article and may aid in the development for future HCC research themes.

Workshifting – a tool to manage shortage of nurses? A content analysis at a medical ward at a university hospital in Sweden
Authors: Nyman Tove , Trinh Susanne , Rosengren Kristina
Published: March 2019

Background: Workshifting is a new model for redistributing tasks due to the shortage of health professionals such as registered nurses (RNs). Therefore, this study aim to describe registered nurses' experiences with workshifting in a medical ward at a university hospital in Sweden.Methods: Manifest qualitative content analysis with an inductive approach was used based on seven semi-structured interviews with RNs working in a medical ward at Sahlgrenska University Hospital in Gothenburg, Sweden.Results: One category, communication skills for increased cooperation, and three subcategories, Manage different skills, Changed work content and Lack of holistic nursing, were described. A healthy work environment (reasonable workload, interesting work tasks/content) is an important factor for attracting health professionals such as RNs.Conclusion: Workshifting redistributes tasks to added staff members such as pharmacists and assistant nurses, which decreases the RN workload; however, task-oriented work results in the lack of a holistic view of nursing. Moreover, enlarged teams need well-developed communication arenas to ensure patient safety and efficient work organization.

Introduction: The recognized association between erectile dysfunction (ED) with lower urinary tract symptoms (LUTS) from high-income countries is unreported from Africa. Authentic figures on prevalence of ED and LUTS from Africa are scarce in the literature. This study was conducted to quantify sexual function and satisfaction among Ugandan men in relation to LUTS severity.

Methods: A convenience sample of men participating in a parallel, cross-sectional survey was used. The population, men >55 years living in Sheema district, Uganda, were recruited into two cohorts: those living in the community and those seeking clinic care due to bother from LUTS. This was to ensure inclusion of a full spectrum of LUTS. The instruments were the International Prostate Symptom Score (IPSS) to quantify LUTS and the Epstein Inventory (EI) to assess four measures of sexual functioning. Bivariate analysis compared community and clinic cohort participants, LUTS severity, and each sexual functioning item with two-sample t-tests for means and Chi-square tests of independence for categorical versions.

Results: Participants included 415 men (238 community and 177 clinic) at mean age of 67.5 years vs. 62.9 (p<0.001) with mean IPSS of 9.32 vs. 17.07 (p≤0.001). Lower mean satisfaction with sexual activity and frequency of erections occurred in the clinic cohort (p≤0.001). Overall, all four questions assessing dissatisfaction with sexual function were significantly correlated with worsening LUTS; sexual satisfaction and frequency of sexual drive were also influenced by age and low levels of education.

Conclusions: These are the first data describing the severity relationship between LUTS and ED in African men. Respondents reported dissatisfaction in the past year with the level of their sexual activity, frequency of sexual drive, ability to have erections, and sexual performance that related statistically to the severity of their LUTS.

Published: February 2019

Introduction: Natesto®, testosterone nasal gel (TNG) is an intranasal testosterone therapy (TTh) used to restore testosterone levels and improve symptoms of hypogonadism. Treatment requires application two (bid) or three (tid) times daily. The Treatment Satisfaction Questionnaire for Medication (TSQM) and a Patient Preference and Use (PPU) Questionnaire were used to obtain patient feedback on the use of TNG and compare to experience with topical TTh.

Methods: The study enrolled 24 TTh-naive (TThN) and 93 TTh-experienced (TThE) hypogonadal men. Treatment lasted up to 120 days, with titration at day 90 to determine the most appropriate dose for restoration of testosterone levels (11 mg bid or tid). Patient satisfaction and symptom changes were measured at days 0, 30, 60, 90, and 120. The PPU Questionnaire was performed at study entry and study completion.

Results: Symptoms improved from baseline (30.6) to day 90 (35.1) (p<0.0001; +15%), consistent with testosterone replacement. TNG increased scores for effectiveness (+20%), convenience (+30%), and global satisfaction (+3%) as compared to their previous topical TTh. TThE patients reported ease of use, convenience, efficacy/effectiveness, and travel friendliness as “likes” of TNG therapy. Overall, 67.2% of patients agreed or strongly agreed that they preferred TNG over topical TTh and 59% sought a prescription to continue treatment with TNG.

Conclusions: Patients switching from topical TTh to TNG reported significant improvements in symptoms and patient satisfaction compared to their previous topical TTh. Patients also reported a significant improvement in convenience with TNG despite two to three times daily application. Preference, satisfaction, and convenience may translate to better treatment compliance.
Seeing is Predicting: Water Clarity-Based Nowcast Models for E. coli Prediction in Surface Water
Authors: Dada Christopher A.
Published: March 2019

Given the 24–48 h turn-around time of conventional surveillance approaches, methods are needed that improve the timeliness and accuracy of recreational water quality risk assessments. Although one useful approach is to combine existing monitoring programmes with predictive faecal indicator bacteria (FIB) models, these models are largely ‘top-down’ in their approach to safeguarding public health. Beyond being simply ‘advised when to avoid swimming’, there is an increasing awareness amongst the general public regarding the role they can play in water quality monitoring. Using quantile, maximum value and optimized incremental modelling approaches, this study reports on the possibility of developing intuitive, public-friendly models that are based on the physical appearance of water (clarity), to estimate 8103 nation-wide E. coli concentrations in rivers, and to assess whether water is safe to swim in. If swimmers were to avoid river waters with <1.1 m black disc visibility during autumn and summer, and river waters with values <0.5 m black disc visibility during spring and winter, they would also avoid microbial hazards that are associated with exceedances of the 540 CFU/100 mL single sample bathing water standard. Regardless of the climatic season, stream order classification, catchment land cover or geology of streams considered, the clarity-based E. coli models performed well as they presented with sensitivity, specificity and accuracy values of at least 72%. The developed models offer the benefit of providing a faster method for estimating E. coli concentration, potentially engaging the public in water monitoring, and allowing them to make informed decisions on whether it is safe to swim.

Empirical studies show that market concentration and pricing policies regulation have an important impact on price transmission. These factors lead to an asymmetric price transmission, particularly in agricultural commodities markets. This paper investigates farm-retail price transmission along the Canadian dairy and pork values chains using Threshold Autoregressive, Momentum Threshold Autoregressive, Error Correction Models and Granger causality test. Using monthly price data, we found that farm-retail price transmission is asymmetric in short and long-term between raw milk and butter price while it is symmetric in the cheese case. In the pork sector, price transmission is asymmetric in long-term and symmetric in short-term between farm price and respectively pork chops and bacon prices. Because of processor and retailer concentration, consumer prices respond more quickly to upward than downward of farm prices. The processors, retailers and distributors concentration along the value chain in Canadian dairy and pork sectors and the supply management regulation policies as well as income stabilization insurance program are the main factors generating this market structure. Consideration of the characteristics of farmers, processors, and retailers in the value chain and the actors’ potential reactions to the agricultural policy could better protect consumers and producers from market distortion.

Published: March 2019

Objetivo: Os investimentos em Business Intelligence and Analytics (BIA) são cada vez mais essenciais para a competitividade das empresas. Apoiado na Visão Baseada em Recursos (VBR), este estudo analisou a implementação de um sistema de BIA no Banco Nacional de Desenvolvimento Econômico e Social (BNDES) para avaliar a geração de valor para a organização. Método: Coletamos dados qualitativos por meio de entrevistas, observação participante e em documentos internos e comunicações.  A análise dos dados seguiu o processo usual de codificação, agregação e síntese, com auxílio do Atlas.ti, um software de análise de dados qualitativos. Originalidade: As abordagens tradicionais de avaliação de investimentos em Tecnologia da Informação (TI), especialmente no caso de sistemas de BIA, negligenciam a natureza dinâmica e as influências mútuas dos ativos e capacidades de TI e as capacidades sócio-organizacionais complementares, no processo de geração de valor para o negócio. Além disso, a Visão Baseada em Recursos tem sido pouco empregada no estudo do impacto de sistemas de BIA nas organizações. Resultados: Os resultados do estudo revelaram o papel fundamental desempenhado pelos recursos e capacidades organizacionais e de TI no processo de adoção de BIA, bem como a importância da dinâmica de complementaridade e seus resultados positivos. Contribuições teóricas: Nesta pesquisa, fornecemos evidências do potencial da VBR para elucidar as complexidades envolvidas no uso da TI para a geração de valor para o negócio sustentável, e, portanto, para explicar os diferentes resultados obtidos por organizações que adotam sistemas de BIA.
