Forecasting World Tuna Catches with ARIMA-Spline and ARIMA-Neural Networks Models
Authors: LEE Boonmee , SUHARTONO Suhartono , LIM Apiradee , AHN Sung Keuk
Published: August 2021

Tuna is a renewable resource that has been managed regionally, but its worldwide capacity for regeneration is still little known. A time-series dataset of tuna catches was used to develop nonlinear univariate models for monitoring the sustainability of tuna catches. Two approaches were compared: 1) fitting an ARIMA-spline model to the volume of annual tuna catches and 2) combining neural networks with an ARIMA model to fit the annual changes in volume. These models offer competitive forecasting performance with small percentage errors. By averaging results of the best model developed in each of these approaches, our ensemble forecast predicts that world tuna catches will reach the optimal level of 5.09 million tons in 2025, remain stable thereafter until 2033, and start decreasing about 0.78 % annually. These models could be used by regional fishery management groups to discover discrepancies between such projections and other science-based estimations of the maximum sustainable output.
HIGHLIGHTS

AnARIMA-spline model is practical for forecasting time series with uncertainties and complex interaction of variables
The plausibility of forecasts is essential as the goodness of fit for statistical model validation
The ensemble forecasts of results from modelling both catches and the changes of catches offer an alternative view for monitoring trend of fishery practices

Clustering Pandemic COVID-19 and Relationship to Temperature and Relative Humidity Among the Tropic and Subtropic Region
Authors: Giarno Giarno
Published: August 2021

The outbreak of Novel Corona Virus (COVID-19) has been spreading almost in all countries of the world and become a deadly pandemic. The infections and deaths vary from high in some countries and low in others. The weather conditions significantly affect life, including viruses. In low temperature and humidity the spreading of coronavirus is expected to be fast and massive, and on the other hand, high temperature and humidity decreases the virus. However, recent data of COVID-19 shows that in tropical region infection and deaths vary of which there is a need of thorough spreading analysis. The clustering of infections and mortality at the beginning of COVID-19 outbreak was group based on the country’s profile similarity, and associated with the meteorological factors. The result shows that countries such as China, Spain, Italy and the United States have very severe attacks of COVID-19 infection. Furthermore, countries with the potential real threats of COVID-19 infections are Austria, Australia, Azerbaijan, Belgium, Bahrain, Brazil, Belarus, Canada, Switzerland, Czech Germany, Denmark, Dominican Republic, Algeria, Ecuador, Estonia, Egypt, Finland, France, Georgia, Croatia, Indonesia, Ireland, Israel, India, Iraq, Iran, Japan, Cambodia, South Korea, Kuwait, Lebanon, Sri Lanka, Lithuania, Monaco, Macedonia, Mexico, Malaysia, Nigeria, Netherlands, Norway, Nepal, New Zealand , Oman, Philippines, Pakistan, Qatar, Romania, Russia, Sweden, Singapore and Thailand. The threat of COVID-19 is not only in dry and humid sub-tropical countries, but it cannot be undermined the effect to some warm and humid tropical countries such as Brazil, Ecuador, Indonesia, Malaysia and the Philippines, which are massively infected, and the mortality rate compared to the population are very high. The study also found that dynamic humidity is a factor that must be considered, especially in the tropics.
HIGHLIGHTS

The COVID-19 pandemic that originated in Wuhan, China spreads rapidly around the world
Demographics and weather are thought to influence the spreading and death of COVID-19
Clustering of demographic and weather factors on COVID-19 shows that countries such as China, Spain, Italy, and the United States are experiencing severe attacks of COVID-19 infection
Covid threatens countries with high population density or large populations
Although warm and humid temperatures in the tropics such as Brazil, Ecuador, Indonesia, Malaysia, and the Philippines can a little slow the spreading of infection, the risk of COVID-19 infection remains high

Modersmålsämnets legitimitet i ett förändrat politiskt landskap - En analys av svensk riksdagsdebatt under 2010-talet
Authors: Hedman Christina , Rosén Jenny
Published: August 2021

The legitimacy of the mother tongue subject in a changing political landscape: An analysis of Swedish parliamentary debate in the twenty-tens. This paper highlights and discusses the arguments in favor of, or against Mother Tongue Instruction (MTI) in Swedish parliamentary debate between 2010 and 2020. New to this decade is the entrance of yet another nationalist and populist party with the abolishment of MTI on its political agenda. Building on a critical discourse analytical frame and argumentation analysis, we discuss this party’s rhetoric on MTI – based in an Othering discourse and the construction of MTI as a path to alienation – and the parliamentary counter-voices. The latter mainly concern the role of MTI for development of Swedish and learning in other school subjects, implying that MTI in its own right is subordinated. We argue that this counter-discourse represents a shift in how MTI is legitimized – and in fact plays into assimilationists’ hands – compared to the pluralistic ideology that initially made way for MTI. The importance of scrutinizing political rhetoric is stressed to anticipate political action.

Leadership in motion - close/leadership in practice. The article discusses events from the project ”Leadership in motion”, where the researchers co-walked ten directors in early childhood centers in a big municipality after reorganization of leader teams. The events are impulses used to explore close leadership. Inspired by such post-human perspectives and concepts as diffractions, entanglements and the not-yet-seen, we undertake diffractive readings of events. Through confabulations between researchers and directors, various understandings of close leadership implications are produced and explored. We discuss how close leadership is expressed in the practice of early childhood centers, where everything is entangled and at the same time in motion. When encountering new leader team organization, for example the not-yet-seen, the leaders point to listening, doubt, resistance, and insecurity as part of close/leadership. They are alert to the situations, present in thought, time, and space, with openness and interest for what is coming.
Serum concentrations of Thymidine kinase 1 measured using a novel antibody-based assay in patients with Hodgkin Lymphoma
Authors: Mattsson Ulfstedt Johan , Venge Per , Holmgren Sofia , Enblad Gunilla , Eriksson Staffan , Molin Daniel
Published: August 2021

Background: Thymidine kinase 1 (TK1) is an intracellular protein associated with DNA synthesis, expressed during the G1 phase and remained elevated through the M phase, with a potential as a biomarker for cell proliferation. In this study, we explore the possible use of TK1 in Hodgkin lymphoma (HL).

Methods: Serum concentrations of TK1 (S-TK1) were measured in 46 newly diagnosed HL patients using prospectively collected biobanked serum samples. The samples were analyzed using a novel antibody-based TK1 immunosorbent assay (ELISA).

Results: The concentrations of S-TK1 were elevated in HL patients compared with healthy controls (median 0.32 μg/L vs. 0.24 μg/L, P = 0.003). A further increase in S-TK1 was observed during the treatment. The S-TK1 concentrations were higher in patients with advanced stage disease, low B-Hb, elevated P-LD and in those with B-symptoms. A high ESR correlated with low S-TK1.

Conclusions: The study results suggest that S-TK1, measured using a novel antibody-based assay, has the potential to be a biomarker in HL. However, while S-TK1 levels are elevated at baseline compared with healthy controls, a limited number of patients and comparatively short follow-up time render reliable conclusions difficult.
Epistemologia de Certeau e sua Contribuição para os Estudos Baseados em Prática em Organizações
Authors: Machado Rafael Carvalho , Chropacz Franciely , Bulgacov Yara Lucia Mazzioti
Published: August 2021

O enfoque deste ensaio teórico é apresentar contribuições para possibilidades de pesquisa, sob a perspectiva epistemológica apresentada na obra A Invenção do Cotidiano, de Michel de Certeau, para os estudos organizacionais, especialmente para os estudos baseados em prática. A compreensão de fundamentos ontoepistemológicos associados à leitura retrospectiva dessa obra permitiu estabelecer uma agenda de pesquisa para os estudos baseados em práticas na perspectiva certeauniana. Escolheu-se essa obra porque nela o filósofo destina o seu olhar para as práticas cotidianas, o que o coloca entre os teóricos da “virada da prática”. Nela, as ocorrências diárias revelam como a sociedade recebe e consome aquilo que lhe é dado. A contribuição de Certeau para a compreensão do processo de mudança organizacional, em especial nos campos de aprendizagem organizacional e cultura, revelam a importância das micro-ocorrências do cotidiano e como sua perspectiva atribui agência a atores organizacionais a quem a literatura tradicional só atribui papel de reprodução. Ao identificar algumas contribuições e possibilidades da perspectiva do filósofo francês no campo dos estudos organizacionais, este ensaio propõe suas aplicações em estudos de mudança organizacional e organizações não tradicionais, além de conceitos sensibilizadores para a compreensão da lógica da prática social.

Published: August 2021

O conceito de cocriação de valor tem ganhado força no contexto empresarial como mecanismo para obtenção de vantagem competitiva. Compreender como os elementos da cocriação de valor são estimulados ou se desenvolvem na empresa é um gap na literatura. Este trabalho visa analisar de que modo os elementos presentes nos modelos de cocriação de valor e nas abordagens de diálogo entre stakeholders se apresentam numa empresa fornecedora de tecnologia para empresas do setor de turismo e hospitalidade. O trabalho está baseado, principalmente, nos estudos de Seppa e Tanev (2011); Ranjan e Read (2016); Prahalad e Ramaswamy (2004); Vargo, Akaka e Maglio (2008); Grissemann e Sauer (2012); Grõnross (2006); Raja e Yazdanifard (2015). Caracteriza-se como uma pesquisa exploratória, qualitativa e estudo de caso. Conclui-se que a cocriação de valor se faz presente, para que produtos e serviços se mantenham atualizados e para que a empresa se mantenha no mercado, a partir de um conjunto de práticas, como: colaboração, engajamento, transparência, reciprocidade, uso dos recursos mútuos, diálogo, interatividade e compartilhamento de aprendizado entre os stakeholders. Tais ações validam a cocriação de valor como uma estratégia para empresas do setor de turismo e hospitalidade. Por fim, entender como os elementos da cocriação emergem ou são utilizados na empresa pode criar um caminho para a replicação das ações.
Materializing the Bible
Authors: Bielo James S.
Published: August 2021

What happens when the written words of biblical scripture are transformed into experiential, choreographed environments? To answer this question, anthropologist James Bielo explores a diverse range of practices and places that “materialize the Bible”: gardens, theme parks, shrines, museums, memorials, exhibitions, theatrical productions, and other forms of replication. Integrating ethnographic, archival, and mass media data, case studies focus primarily on U.S. Christianity from the late 19th century to the present.

Composed as 20 short chapters that may be read in any order, the book is divided into three sections. Section I, “Variations on Replication,” examines examples that recontextualize elements from the (actual or imagined) biblical past. Section II, “The Power of Nature,” turns to the natural world associated with Christian scripture and how it is mobilized as a privileged media. Section III, “Choreographing Experience,” examines lived interactions with the affordances of materializing the Bible. Through processes of circulation, design, and classification, these chapters demonstrate how these performances are oriented and engineered.

Materializing the Bible is a comparative and thoroughly interdisciplinary work, engaging scholarship in material religion, the anthropology of religion, pilgrimage and tourism studies, folklore, linguistic anthropology, and social theory. Bielo argues that materializing the Bible works as an authorizing practice to intensify intimacies with scripture and circulate potent ideologies. Performed through the sensory experience of bodies, physical technologies, and infrastructures of place, Bielo illustrates how this phenomenon is always, ultimately, about expressions of power.

Fashion imagery has existed for hundreds of years and yet the methods used by scholars to understand it have remained mostly historical and descriptive. The belief informing these approaches may be that fashion imagery is designed for one purpose: to depict a garment and how to wear it. In this interdisciplinary book, Sanda Miller suggests a radical alternative to these well-practiced approaches, proposing that fashion imagery has stories to tell and meanings to uncover. The methodology she has developed is an iconography of fashion imagery, based on the same theory which has been key to the History of Art for centuries.

Applying Panofsky’s theory of iconography to illustrations from books, magazines and fashion plates, as well as to fashion photography and even live fashion events, Miller uncovers three levels of meaning: descriptive, secondary (or conventional) and tertiary or ‘symbolic’. In doing so, she answers questions such as: who is the model; what did people wear and why; and how did people live? She proves that fashion imagery, far from being purely descriptive, is ripe with meaning and can be used to shed light on society, class, culture and the history of dress.

Introdução: O trabalho do psicólogo no ambulatório objetiva oferecer suporte ao paciente durante todo o processo de adoecimento, auxiliar na compreensão da vivência do adoecimento, fortalecer o enfrentamento a doença, suscitar maior adesão ao tratamento e promover saúde mental como forma de potencializar as possibilidades de autocuidado. Objetivo: Descrever as percepções de residentes de diversas áreas acerca da atuação do psicólogo na equipe multiprofissional. Metodologia: Trata-se de um relato de experiência que descreve percepções de residentes de diferentes áreas de formação a respeito do papel do psicólogo na equipe. A experiência ocorreu de março a junho de 2021 em um ambulatório multiprofissional especializado em saúde da mulher, de um Hospital Universitário. O ambulatório oferece consultas multiprofissionais contando com a presença de psicólogo, farmacêutico, nutricionista e profissional de educação física. A atuação do psicólogo se estende também a realização de triagens estendidas com algumas pacientes e intervenções pontuais com a equipe. Resultados: A participação do psicólogo nas consultas multiprofissionais contribuiu para uma maior organização psíquica das pacientes, de forma que puderam elaborar melhor seus relatos e receber as orientações mais satisfatoriamente. Ao realizar intervenções diretamente com a equipe, o profissional contribuiu para a prática de atendimentos mais humanizados. Já nas consultas de triagem estendida, foi possível identificar demandas psíquicas, oferecendo então escuta e encaminhamentos adequados. Considerações Finais: A presença do psicólogo na equipe multiprofissional contribuiu para uma visão integral da saúde das pacientes, considerando os fatores psíquicos inerentes ao processo saúde-doença. Ao contar com a perspectiva deste profissional a equipe tornou-se mais humanizada em seus atendimentos e mais atenta a sinais de risco que alertem para o adoecimento psíquico das mulheres atendidas.
Not All NGOs are Treated Equally: Selectivity in Civil Society Management in China and Russia
Authors: Plantan Elizabeth
Published: August 2021

How do autocrats manage civil society? I develop a typology of authoritarian responses to civil society and show how leaders employ selective policies to adjudicate among risks and benefits in the third sector. Using data on laws managing foreign support of civil society in China and
Russia, I find evidence of selective implementation that reveals which groups are seen as threatening or beneficial. While there are some similarities across the two countries, I find a divergence in their response to environmental groups, who are selectively repressed or neglected in Russia
but selectively encouraged or co-opted in China. Using fieldwork interviews, I conduct a case study to show that while environmental groups in both countries pose some risk, the key difference is their perceived benefit.

“Isto é meu corpo” (que é dado por vós): o grotesco, a tortura e o sacrifício no romance Agá, de Hermilo Borba Filho"
Authors: Farias Luiz Roberto Leite
Published: August 2021

Neste artigo, baseado no romance Agá, de Hermilo Borba Filho, propomos um olhar crítico sobre os corpos dos torturados, que os confunde com o corpo deformado de Cristo, além de que essa analogia torna o chão da cela da prisão também em uma verdadeira mesa de dissecação. Assim, o olhar sobre os corpos dos torturados confunde-se com o olhar de um anatomista que mapeia a ação do poder sobre os corpos como forma de erigir um memorial da tortura, um testemunho que preserve a memória dos que perderam a vida nos porões da repressão no Brasil.
The hidden sell : subversive advertising of fashion products in social media
Authors:   , Smith Helen
Published: August 2021

With the exorbitant growth in technological presence and the introduction of social media, a whole new realm of advertising and marketing possibilities has been opened to businesses. This study investigated people’s perceptions of the use of social media for advertising fashion products under the guise of social media interaction. In other words, online marketing is seen as “subversive” as it is a deceptive form of advertising using celebrity allure to attract prospective clients. The target population comprised females between the ages of eighteen and twenty-nine as this population was found to represent the majority of social media users. The purpose of the study was to establish whether the social media users canvassed were aware of this subversive type of advertising, whether they responded by buying the products, and how effective they found this type of marketing overall. The research was carried out within a social constructivist framework, using a nested/embedded strategy in a mixed-methods approach. Users of social networking in South Africa were recruited by means of an Instagram post which introduced the idea of the “subversive sell” and gave them the option of participating in an online survey on the topic. Respondents were also offered the option of participating in two focus groups in the Durban area in order to obtain more in-depth feedback on this marketing strategy. Results showed that participants were aware of the fact that they were being targeted, and that they saw it as an inevitable outcome of using social media. However, it irritated them when realising that social media were saturated with advertisements, and that they should be importuned incessantly with such. They also reported that they would not necessarily purchase fashion products advertised in this way and would rather rely on word-of-mouth recommendations on social media from people using these products. Respondents did, however, comment on the immediacy and novelty of this form of advertising. It was concluded that subversive advertising via social media was not that different from the celebrity endorsements found in traditional media, and that people were responding to this strategy in similar ways.
Continuity of Unconstitutional and Illegal Action on the Political Scene in Bosnia and Herzegovina from the End of the Xix Century to the Present Day – Reality or Imagination
Authors: Huseinspahić Ajdin , Dedić Sedad
Published: August 2021

From the time of the Austro-Hungarian occupation of Bosnia and Herzegovina (BiH) until today, there have been occasional but continuous attacks on the territory, the population, and sovereignty of Bosnia and Herzegovina. No matter how the agreements of the Novi Pazar Convention, the Sangermen Peace Treaty, the Vidovdan Constitution, or the Zavnobih principles were violated and circumvented, the attack on the independent, sovereign, and complete BiH, a country of equal peoples and others, ie citizens, continued with equal intensity after the 1990s. XX century until today. The paper presents the continuity of fraud in terms of legal regulations, ie the legal order of Bosnia and Herzegovina.
We are witnessing continuous unconstitutional and illegal activities in BiH, and whose political mentors and tutors almost always came from outside BiH, while the concrete action was carried out and is still carried out by certain Bosnian Serb and Croat political entities who often behave completely servilely concerning the national policies of neighboring countries: Croatia and Serbia, but also certain international factors due to the consequences of Islamophobia are often willing to ignore the rule of law and human rights in Bosnia and Herzegovina, what they jealously protect in their countries.
The example of promoting the unconstitutional Day of the Republika Srpska entity and the overall state of legal unfoundedness and political hysteria created around it testifies to the claim that the political destiny of this country is still largely conditioned by local servility, and not by correct political-partnership relations with Serbia and Croatia.
Given this, it is quite certain that the constitutional consistency and consociational model of democracy as well as the principle of the constituency of the people, although a big noose around the neck of this country on the path to a civil state and full realization of human rights, is extremely important legal and political support in Bosniak and all other patriotic forces in Bosnia and Herzegovina, which should be used properly in an insincere and ill-intentioned environment.
The work in front of you contains two interrelated parts, the first part which refers to several historically important legal documents, from the end of the 19th century, which are mala fide the activity of different
subjects, who initially proclaimed them and even stood behind them, played or derogated fraus legis, and the second part indicates the continuity of these actions, both domestically and internationally when it comes to the current time and recent history of political and legal relations in BiH.
Interpreting estimated observation error statistics of weather radar measurements using the ICON-LAM-KENDA system

Published: August 2021

Abstract. Assimilation of weather radar measurements including radar reflectivity and radial wind data has been operational at the Deutscher Wetterdienst,
with a diagonal observation error (OE) covariance matrix. For an implementation of a full OE covariance matrix,
the statistics of the OE have to be a priori estimated, for which the Desroziers method has been often used.
However, the resulted statistics consists of contributions from different error sources and are difficult to interpret.
In this work, we use an approach that is based on samples for truncation error in radar observation space to approximate the representation error due to unresolved scales and processes (RE)
and compare its statistics with the OE statistics estimated by the Desroziers method. It is found that
the statistics of the RE help the understanding of several important features in the variances and correlation length scales of the OE for both reflectivity and radial wind data
and the other error sources from the microphysical scheme, radar observation operator and the superobbing technique may also contribute,
for instance, to differences among different elevations and observation types.
The statistics presented here can serve as a guideline for selecting which observations are assimilated and for assignment of the OE covariance matrix that can be diagonal or full and correlated.
Automated detection of atmospheric NO2 plumes from satellite data: a tool to help infer anthropogenic combustion emissions
Authors: Finch Douglas , Palmer Paul , Zhang Tianran
Published: August 2021

Abstract. We use a convolutional neural network (CNN) to identify plumes of nitrogen dioxide (NO2), a tracer of incomplete combustion, from NO2 column data collected by the TROPOspheric Monitoring Instrument (TROPOMI). This approach allows us to exploit efficiently the growing volume of satellite data available to characterize Earth’s climate. For the purposes of demonstration, we focus on data collected between July 2018 and June 2020. We train the deep learning model using six thousand 28 × 28-pixel images of TROPOMI data (corresponding to 266 × 133 km2) and find that the model can identify plumes with a success rate of 90 %. Over our study period, we find over 310,000 individual NO2 plumes of which 9 % are found over mainland China. We have attempted to remove the influence of open biomass burning using correlative high-resolution thermal infrared data from the Visible Infrared Imaging Radiometer Suite (VIIRS). We relate the remaining NO2 plumes to large urban centres, oil and gas production, and major power plants. We find no correlation between NO2 plumes and the location of natural gas flaring. We also find persistent NO2 plumes from regions where inventories do not currently include emissions. Using an established anthropogenic CO2 emission inventory, we find that our NO2 plume distribution captures 92 % of total CO2 emissions, with the remaining 8 % mostly due to a large number of small sources < 0.2 gC/m2/day for which our NO2 plume model is less sensitive. We argue the underlying CNN approach could form the basis of a Bayesian framework to estimate anthropogenic combustion emissions.

Abstract. Across the Qinghai–Tibet Plateau (QTP) there is a narrow
engineering corridor with widely distributed slopes called the
Qinghai–Tibet Engineering Corridor (QTEC), where a variety of important
infrastructures are concentrated. These facilities are transportation routes
for people, materials, energy, etc. from inland China to the Tibet Autonomous Region. From
Golmud to Lhasa, the engineering corridor covers 632 km of permafrost
containing the densely developed Qinghai–Tibet Railway and Qinghai–Tibet Highway, as well
as power and communication towers. Slope failure in permafrost regions, caused
by permafrost degradation, ground ice melting, etc., affects the engineering
construction and permafrost environments in the QTEC. We implement a variety
of sensors to monitor the hydrological and thermal deformation between
permafrost slopes and permafrost engineering projects in the corridor. In
addition to soil temperature and moisture sensors, the global navigation
satellite system (GNSS), terrestrial laser scanning (TLS), and unmanned
aerial vehicles (UAVs) were adopted to monitor the spatial distribution and
changes in thermal deformation. An integrated dataset of
hydrological and thermal deformation in permafrost engineering and slopes in the
QTEC from the 1950s to 2020, including meteorological and ground
observations, TLS point cloud data, and RGB and thermal infrared (TIR)
images, can be of great value for estimating the hydrological and thermal impact
and stability between engineering and slopes under the influence of climate
change and engineering disturbance. The dataset and code were uploaded to
the Zenodo repository and can be accessed through
https://zenodo.org/communities/qtec (last access: 23 June 2021), including meteorological and ground

Abstract. We present the first incorporation of the Common Representative
Intermediates version 2.2 tropospheric chemistry mechanism, CRI v2.2,
combined with stratospheric chemistry, into the global chemistry–climate
United Kingdom Chemistry and Aerosols (UKCA) model to give the CRI-Strat 2
mechanism. A rigorous comparison of CRI-Strat 2 with the earlier version,
CRI-Strat, is performed in UKCA in addition to an evaluation of three
mechanisms, CRI-Strat 2, CRI-Strat and the standard UKCA chemical mechanism,
StratTrop v1.0, against a wide array of surface and airborne chemical data. CRI-Strat 2 comprises a state-of-the-art isoprene scheme, optimized against
the Master Chemical Mechanism v3.3.1, which includes isoprene peroxy radical isomerization,
HOx recycling through the addition of photolabile hydroperoxy aldehydes
(HPALDs), and isoprene epoxy diol (IEPOX) formation. CRI-Strat 2 also features updates to several
rate constants for the inorganic chemistry, including the reactions of
inorganic nitrogen and O(1D). The update to the isoprene chemistry in CRI-Strat 2 increases OH over the
lowest 500 m in tropical forested regions by 30 %–50 % relative to
CRI-Strat, leading to an improvement in model–observation comparisons for
surface OH and isoprene relative to CRI-Strat and StratTrop. Enhanced
oxidants also cause a 25 % reduction in isoprene burden and an increase in
oxidation fluxes of isoprene and other biogenic volatile organic compounds
(BVOCs) at low altitudes with likely impacts on subsequent aerosol formation, atmospheric
lifetime, and climate. By contrast, updates to the rate constants of O(1D) with its main
reactants relative to CRI-Strat reduces OH in much of the free troposphere,
producing a 2 % increase in the methane lifetime, and increases the
tropospheric ozone burden by 8 %, primarily from reduced loss via
O(1D)+H2O. The changes to inorganic nitrogen reaction rate
constants increase the NOx burden by 4 % and shift the distribution
of nitrated species closer to that simulated by StratTrop. CRI-Strat 2 is suitable for multi-decadal model integrations and the
improved representation of isoprene chemistry provides an opportunity to
explore the consequences of HOx recycling in the United Kingdom Earth
System Model (UKESM1). This new mechanism will enable a re-evaluation of the
impact of BVOCs on the chemical composition of the atmosphere and further probe
the feedback between the biosphere and the climate.

GEE TIMESERIES EXPLORER FOR QGIS – INSTANT ACCESS TO PETABYTES OF EARTH OBSERVATION DATA
Authors: Rufin P. , Rabe A. , Nill L. , Hostert P.
Published: August 2021

Abstract. Earth observation analysis workflows commonly require mass processing of time series data, with data volumes easily exceeding terabyte magnitude, even for relatively small areas of interest. Cloud processing platforms such as Google Earth Engine (GEE) leverage accessibility to satellite image archives and thus facilitate time series analysis workflows. Instant visualization of time series data and integration with local data sources is, however, currently not implemented or requires coding customized scripts or applications. Here, we present the GEE Timeseries Explorer plugin which grants instant access to GEE from within QGIS. It seamlessly integrates the QGIS user interface with a compact widget for visualizing time series from any predefined or customized GEE image collection. Users can visualize time series profiles for a given coordinate as an interactive plot or visualize images with customized band rendering within the QGIS map canvas. The plugin is available through the QGIS plugin repository and detailed documentation is available online (https://geetimeseriesexplorer.readthedocs.io/).
TOWARDS THE INTEGRATION OF AUTHORITATIVE AND OPENSTREETMAP GEOSPATIAL DATASETS IN SUPPORT OF THE EUROPEAN STRATEGY FOR DATA
Authors: Sarretta A. , Minghini M.
Published: August 2021

Abstract. Digital transformation is at core of Europe’s future and the importance of data is well highlighted by the recently published European strategy for data, which envisions the establishment of so-called European data spaces enabling seamless data flows across actors and sectors to ultimately boost the economy and generate innovation. Integrating datasets produced by multiple actors, including citizen-generated data, is a key objective of the strategy. This study focuses on OpenStreetMap (OSM), the most popular crowdsourced geographic information project, and is the first step towards an exploration of pros and cons of integrating its open-licensed data with authoritative geospatial datasets from European National Mapping Agencies. In contrast to previous work, which has only tested data integration at the local or regional level, an experiment was presented to integrate the national address dataset published by the National Land Survey (NLS) of Finland with the corresponding dataset from OSM. The process included the analysis of the two datasets, a mapping between their data models and a set of processing steps – performed using the open source QGIS software – to transform and finally combine their content. The resulting dataset confirms that, while addresses from the NLS are in general more complete across Finland, in some areas OSM addresses provide a higher detail and more up-to-date information to usefully complement the authoritative one. Whilst the analysis confirms that an integration between OSM and authoritative geospatial datasets is technically and semantically feasible, future work is needed to evaluate enablers and barriers that also exist at the legal and organisational level.

Abstract. In this work we present an orbital correction workflow developed with FOSS tools to compensate for orbital errors present in Synthetic Aperture Radar (SAR) interferograms. The technique is tested in forested areas in Argentina, using full polarimetric images from the argentinean SAR constellation SAOCOM-1 (Satélite Argentino Con Microondas). The results are contrasted with field measurements of canopy height provided by local producers, and the results show that the Root Mean Square Error (RMSE) of the satellite measurements is significantly reduced after the orbital correction. Moreover, forest plantation become more distinguishable in the retrieved Digital Surface Models, especially in those pairs with larger spatial baseline. A section of this article is also dedicated to the discussion on which are the best parameters to run the module, and how different configurations can affect the result.

Abstract. Natural hazards such as landslides, whether they are driven by meteorologic or seismic processes, are constantly shaping Earth’s surface. In large percentage of the slope failures, they are also causing huge human and economic losses. As the problem is complex in its nature, proper mitigation and prevention strategies are not straightforward to implement. One important step in the correct direction is the integration of different fields; as such, in this work, we are providing a general overview of approaches and techniques which are adopted and integrated for landslide monitoring and mapping, as both activities are important in the risk prevention strategies. Detailed landslide inventory is important for providing the correct information of the phenomena suitable for further modelling, analysing and implementing suitable mitigation measures. On the other hand, timely monitoring of active landslides could provide priceless insights which can be sufficient for reducing damages. Therefore, in this work popular methods are discussed that use remotely-sensed datasets with a particular focus on the implementation of machine learning into landslide detection, susceptibility modelling and its implementation in early-warning systems. Moreover, it is reviewed how Citizen Science is adopted by scholars for providing valuable landslide-specific information, as well as couple of well-known platforms for Volunteered Geographic Information which have the potential to contribute and be used also in the landslide studies. In addition to proving an overview of the most popular techniques, this paper aims to highlight the importance of implementing interdisciplinary approaches.

Abstract. Climate, together with human activities, is changing the natural dynamics in lake ecosystems and adding new challenges to the management of water resources. Recent studies on Lake Lugano, in Switzerland, showed for instance that the increased water temperature influence other processes such as lake stratification and mixing dynamics, algal blooms, colonisation by alien species, affecting the lake ecosystem as a whole. In such situation, real-time systems with high frequency measurements, together with the traditional discrete monitoring, can help in understanding dynamics and processes occurring on short time scales. To this aim, an open monitoring system largely composed by open source components is being developed for the high frequency monitoring of Lake Lugano. The system relies on the open source software istSOS either on the server and node sides applying the edge computing paradigm which is more and more adopted in the Internet of Things field. The implementation collects temperature and dissolved oxygen data from sensors positioned at six different depths of the lake and transmits them using the LoRa radio frequency to a data warehouse. At server side, the software architecture adopts the evolving technology based on containers where services can be grouped in a compose and easily deployed on a server. This paper aims to describe the adopted open source technology and demonstrate that it can be successfully used also in environmental monitoring where the accessibility is limited and the weather conditions can be unpredictable.

Abstract. Collaborative projects imply a wide variety of skills, ranging from technical abilities to teamwork and problem-solving attitudes. Innovative teaching programmes focused on the use and promotion of open-source geospatial tools represent a key element in developing such transversal abilities. OpenStreetMap (OSM) brings into play open and collaborative dynamics that build a critical ecosystem where single contributions are part of collective intelligence. This initiative led to the foundation of structured contributors groups such as PoliMappers, the first European YouthMappers chapter based in Politecnico di Milano (Italy). Pursuing the objective to build a responsible student-led community of Free and Open Source Software users, in 2021 PoliMappers organised the course entitled “Collaborative and Humanitarian Mapping”. The programme is structured into 7 meetings and aims to introduce university students to the OSM environment with a focus on the potential of open data and related geospatial tools, especially in the humanitarian field. It has seen the participation of the World Food Programme, Open Knowledge Foundation, TECHO Colombia, IMM Design Lab, Map for Future, UN Mappers, Spazio Vita Niguarda Onlus, Ledha Milano, AUS Niguarda Onlus and Humanitarian OpenStreetMap Team. Enrolled attendants’ contributions have been assessed with tools for quality review and statistics. Also, Q&As and suggestions to the attendants have been collected to detect common issues. The paper presents the course, from the design to the assessment of the students’ activities, and the lessons learned in this experience in such a way to provide some guidance to those who want to organize similar initiatives.
Vectors to ore in replacive volcanogenic massive sulfide (VMS) deposits of the northern Iberian Pyrite Belt: mineral zoning, whole rock geochemistry, and application of portable X-ray fluorescence

Abstract. In this work we have performed a detailed study of
vectors to ore to a representative volcanic-rock-hosted replacive volcanogenic massive sulfide (VMS)
deposit located in the northern Iberian Pyrite Belt (Spain), the Aguas
Teñidas deposit. The investigated vectors include the following: (1) mineralogical
zoning, (2) host sequence characterization and mineralized unit
identification based on whole rock geochemistry discrimination diagrams, (3)
study of the characteristics and behaviour of whole rock geochemical
anomalies around the ore (e.g. alteration-related compositional changes,
characteristics and extent of geochemical halos of indicative elements such
as Cu, Zn, Pb, Sb, Tl, and Ba around the deposit), and (4) application of
portable X-ray fluorescence (p-XRF) analysis to the detection of the
previous vectors. In the footwall, a concentric cone-shaped hydrothermal alteration zone
bearing the stockwork passes laterally, from core to edge, from quartz (only
local) to chlorite–quartz, sericite–chlorite–quartz, and sericite–quartz
alteration zones. The hydrothermal alteration is also found in the hanging
wall despite being tectonically allochthonous to the orebody: a proximal
sericite alteration zone is followed by a more distal albite-rich one. Whole rock
major elements show an increase in alteration indexes (e.g. AI, CCPI)
towards the mineralization, a general SiO2 enrichment, and FeO
enrichment as well as K2O and Na2O depletion towards the centre of the
hydrothermal system, with MgO showing a less systematic behaviour. K2O
and Na2O leached from the centre of the system are transported and
deposited in more external areas. Copper, Pb, and Zn produce proximal
anomalies around mineralized areas, with the more mobile Sb, Tl, and Ba
generating wider halos. Whereas Sb and Tl halos form around all mineralized
areas, Ba anomalies are restricted to areas around the massive sulfide
body. Our results show that proposed vectors, or adaptations designed to
overcome p-XRF limitations, can be confidently used by analysing unprepared
hand specimens, including the external rough curved surface of drill cores. The data presented in this work are not only applicable to VMS exploration
in the Iberian Pyrite Belt, but on a broader scale they will also contribute to improving our
general understanding of vectors to ore in replacive-type VMS deposits.
The distribution and evolution of supraglacial lakes on 79° N Glacier (north-eastern Greenland) and interannual climatic controls

Abstract. The Nioghalvfjerdsfjorden glacier (also known as the 79∘ North Glacier) drains approximately 8 % of the Greenland Ice Sheet. Supraglacial lakes (SGLs), or surface melt ponds, are a persistent summertime feature and are
thought to drain rapidly to the base of the glacier and influence seasonal ice
velocity. However, seasonal development and spatial distribution of SGLs in
the north-east of Greenland are poorly understood, leaving a substantial error in the estimate of meltwater and its impacts on ice velocity. Using results from an automated detection of melt ponds, atmospheric and surface mass
balance modelling, and reanalysis products, we investigate the role of specific climatic conditions in melt onset, extent, and duration from 2016 to 2019. The summers of 2016 and 2019 were characterised by above-average air temperatures, particularly in June, as well as a number of rainfall events, which led to
extensive melt ponds to elevations up to 1600 m. Conversely, 2018 was
particularly cold, with a large accumulated snowpack, which limited the
development of lakes to altitudes less than 800 m. There is evidence
of inland expansion and increases in the total area of lakes compared to the
early 2000s, as projected by future global warming scenarios.
