Published: February 2018

Abstract. The Precision Solar Spectroradiometer (PSR) is a new spectroradiometer
developed at Physikalisch-Meteorologisches Observatorium Davos – World
Radiation Center (PMOD–WRC), Davos, measuring direct solar irradiance at the
surface, in the 300–1020 nm spectral range and at high temporal resolution. The
purpose of this work is to investigate the instrument's potential to
retrieve integrated water vapour (IWV) using its spectral measurements. Two
different approaches were developed in order to retrieve IWV: the first one
uses single-channel and wavelength measurements, following a theoretical water
vapour high absorption wavelength, and the second one uses direct sun
irradiance integrated at a certain spectral region. IWV results have been
validated using a 2-year data set, consisting of an AERONET sun-photometer
Cimel CE318, a Global Positioning System (GPS), a microwave radiometer profiler (MWP) and radiosonde retrievals recorded at Meteorological
Observatorium Lindenberg, Germany. For the monochromatic approach, better
agreement with retrievals from other methods and instruments was achieved using
the 946 nm channel, while for the spectral approach the 934–948 nm
window was used. Compared to other instruments' retrievals, the monochromatic approach
leads to mean relative differences up to 3.3 % with the coefficient of
determination (R2) being in the region of 0.87–0.95, while for the
spectral approach mean relative differences up to 0.7 % were recorded
with R2 in the region of 0.96–0.98. Uncertainties related to IWV
retrieval methods were investigated and found to be less than 0.28 cm for
both methods. Absolute IWV deviations of differences between PSR and other
instruments were determined the range of 0.08–0.30 cm and only in extreme
cases would reach up to 15 %.

Published: February 2018

Abstract. The ultraviolet index (UVI) is an important tool to raise public awareness of the risks of solar radiation overexposure. However, solar ultraviolet radiation instruments are relatively expensive, and the deployment and maintenance of a large-scale network proved impractical. In this paper, we describe a simple method for UVI and daily erythemal dose retrieval from photosynthetically active radiation (PAR – 0.40–0.70 μm) measurements. These latter are generally performed by cheaper instruments and commonly found in any ordinary meteorological station. Despite the different interactions involving UV and PAR radiation with the atmospheric components, our method is based on the solar position and cloud modification factor (CMF) that exert a quite similar influence on these electromagnetic radiation bands. We also show that this method is not suitable for shortwave radiation sensors (0.25–4.00 μm). A large dataset was used to test this method and the comparisons between UVI measurements and inferences are comparable to the instrumental errors. Thus, in this paper we show a 2nd degree regression equation for obtaining erythemal UV from PAR measurements.

Published: February 2018

Abstract. In recent years, mobile dual-polarisation Doppler X-band radars have become a prevalent part of the atmospheric scientist’s toolkit for examining cloud dynamics and microphysics and making quantitative precipitation estimates. Here we describe the National Centre for Atmospheric Science (NCAS) mobile X-band Dual-polarisation Doppler weather radar (NXPol) and the infrastructure used to deploy the radar and provide an overview of the technical specifications. It is the first radar of its kind in the United Kingdom. The NXPol is a Meteor 50DX manufactured by Selex-Gematronik (Selex ES GmbH), modified to operate with a larger 2.4 m diameter antenna that produces a 0.98° half-power beam width and without a radome. We provide an overview of the technical specifications of the NXPol with emphasis given to the description of the aspects of the infrastructure developed to deploy the radar as an autonomous observing facility in remote locations. To demonstrate the radar’s capabilities, we also present examples of its use in three recent field campaigns and its ongoing observations at the Chilbolton Facility for Atmospheric and Radio Research (CFARR).
Unknown high-frequency (7–12 kHz) quasi-periodic VLF emissions observed on
the ground at L ~ 5.5
Authors: Manninen Jyrki , Kleimenova Natalia , Turunen Tauno , Gromova Liudmila
Published: February 2018

Abstract. We reveal previously unknown quasi-periodic (QP) VLF emissions at the unusual high-frequency band of ~ 7–11 kHz by applying the digital filtering of strong sferics to the ground-based VLF data recorded at Kannuslehto station (KAN). It is located in Northern Finland at L ~ 5.5. The frequencies of QP emissions are much higher than the equatorial electron gyrofrequency at L ~ 5.5. Thus, these emissions must have been generated at much lower L-shells than KAN. Two high-frequency QP emission events have been studied in detail. The emissions were right-hand polarized waves indicating an overhead location of the exit area of waves in the ionosphere. In one event, the spectral-temporal forms of the emissions looked like a series of giant bullets with the very abrupt cessation. Unfortunately, we could not explain such strange shape of the waves. In the second event, the modulation period was about 3 min under the absence of the simultaneous geomagnetic pulsations. The studied emissions lasted about 4 hours and were observed under the very quiet geomagnetic activity. The adequate mechanisms of the generation and propagation of the revealed high-frequency QP emissions have not yet been established. We speculate that studied QP emissions can be attributed to the auto-oscillations of the cyclotron instability in the magnetospheric plasma maser.
A refinement of coccolith separation methods: Measuring the sinking characters of coccoliths
Authors: Zhang Hongrui , Stoll Heather , Bolton Clara , Jin Xiaobo , Liu Chuanlian
Published: February 2018

Abstract. The sinking velocities of individual coccoliths are relevant for export of their CaCO3 from the surface ocean, and for laboratory methods to separate coccoliths of different sizes and species for geochemical analysis. In the laboratory, the repeat settling/decanting method was the earliest method to separate coccolith from sediments for geochemical analyses, and is still widely used. However, in the absence of estimates of settling velocity for non-spherical coccoliths, previous implementations have depended mainly on time consuming empirical method development by trial and error. In this study, the sinking velocities of coccoliths belonging to different species were carefully measured in a series of settling experiments for the first time. Settling velocities of modern coccoliths range from 0.154 to 10.67 cm h−1. We found that a quadratic relationship between coccolith length and sinking velocity fits well and coccolith sinking velocity can be estimated by measuring the coccolith length and using the length-velocity factor, ksv. We found a negligible difference in sinking velocities measured in different vessels. However, an appropriate choice of vessel must be made to avoid hindered settling in coccolith separations. The experimental data and theoretical calculations presented here will support and improve the repeat settling/decanting method.
Land-use change may exacerbate climate change impacts on water resources in the Ganges basin
Authors: Tsarouchi Gina , Buytaert Wouter
Published: February 2018

Abstract. Quantifying how land-use change and climate change affect water resources is
a challenge in hydrological science. This work aims to quantify how future
projections of land-use and climate change might affect the hydrological
response of the Upper Ganges river basin in northern India, which experiences
monsoon flooding almost every year. Three different sets of modelling
experiments were run using the Joint UK Land Environment Simulator (JULES) land surface model (LSM) and covering the
period 2000–2035: in the first set, only climate change is taken into
account, and JULES was driven by the CMIP5 (Coupled Model Intercomparison
Project Phase 5) outputs of 21 models, under two representative concentration
pathways (RCP4.5 and RCP8.5), whilst land use was held fixed at the year
2010. In the second set, only land-use change is taken into account, and
JULES was driven by a time series of 15 future land-use pathways, based on
Landsat satellite imagery and the Markov chain simulation, whilst the
meteorological boundary conditions were held fixed at years 2000–2005. In
the third set, both climate change and land-use change were taken into
consideration, as the CMIP5 model outputs were used in conjunction with the
15 future land-use pathways to force JULES. Variations in hydrological
variables (stream flow, evapotranspiration and soil moisture) are calculated
during the simulation period. Significant changes in the near-future (years 2030–2035) hydrologic fluxes
arise under future land-cover and climate change scenarios pointing towards a
severe increase in high extremes of flow: the multi-model mean of the 95th
percentile of streamflow (Q5) is projected to increase by 63 % under
the combined land-use and climate change high emissions scenario (RCP8.5).
The changes in all examined hydrological components are greater in the
combined land-use and climate change experiment. Results are further
presented in a water resources context, aiming to address potential
implications of climate change and land-use change from a water demand
perspective. We conclude that future water demands in the Upper Ganges region
for winter months may not be met.
Informing a hydrological model of the Ogooué with multi-mission remote sensing data
Authors: Kittel Cecile M. M. , Nielsen Karina , Tøttrup Christian , Bauer-Gottwein Peter
Published: February 2018

Abstract. Remote sensing provides a unique opportunity to inform and constrain a hydrological model and to increase its value as a decision-support tool. In this study, we applied a multi-mission approach to force, calibrate and validate a hydrological model of the ungauged Ogooué river basin in Africa with publicly available and free remote sensing observations. We used a rainfall–runoff model based on the Budyko framework coupled with a Muskingum routing approach. We parametrized the model using the Shuttle Radar Topography Mission digital elevation model (SRTM DEM) and forced it using precipitation from two satellite-based rainfall estimates, FEWS-RFE (Famine Early Warning System rainfall estimate) and the Tropical Rainfall Measuring Mission (TRMM) 3B42 v.7, and temperature from ECMWF ERA-Interim. We combined three different datasets to calibrate the model using an aggregated objective function with contributions from (1) historical in situ discharge observations from the period 1953–1984 at six locations in the basin, (2) radar altimetry measurements of river stages by Envisat and Jason-2 at 12 locations in the basin and (3) GRACE (Gravity Recovery and Climate Experiment) total water storage change (TWSC). Additionally, we extracted CryoSat-2 observations throughout the basin using a Sentinel-1 SAR (synthetic aperture radar) imagery water mask and used the observations for validation of the model. The use of new satellite missions, including Sentinel-1 and CryoSat-2, increased the spatial characterization of river stage. Throughout the basin, we achieved good agreement between observed and simulated discharge and the river stage, with an RMSD between simulated and observed water amplitudes at virtual stations of 0.74 m for the TRMM-forced model and 0.87 m for the FEWS-RFE-forced model. The hydrological model also captures overall total water storage change patterns, although the amplitude of storage change is generally underestimated. By combining hydrological modeling with multi-mission remote sensing from 10 different satellite missions, we obtain new information on an otherwise unstudied basin. The proposed model is the best current baseline characterization of hydrological conditions in the Ogooué in light of the available observations.

Short communication: Melatonin implantation during the non-growing period of cashmere increases the cashmere yield of female Inner Mongolian cashmere goats by increasing fiber length and density
Authors: Wu Ziyuan , Duan Chunhui , Li Yan , Duan Tao , Mo Fang , Zhang Wei
Published: February 2018

This study aimed to evaluate if melatonin implantation at the end of April and June was able to increase cashmere production in female Inner Mongolian cashmere goats and to search for contributing factors accounting for the melatonin increasing in cashmere production. One hundred and fifty female Inner Mongolian cashmere goats (initial body weight 37.2 ± 3.3 kg) were randomly assigned to either a control (n=75) or a treatment (n=75) group. Goats in the treatment group were implanted with melatonin (2 mg/kg of body weight) on April 30 and June 30, 2014 while goats in the control received no treatment. Melatonin implantation increased cashmere yield by 23.4% while increasing the length and density of the cashmere fiber by 19.8% and 11.4%, whereas it decreased cashmere fiber diameter by 4.4%. Melatonin treatment had no effect on doe growth, litter size or birth and weaning weights of kid. Melatonin implantation promoted cashmere yield by increasing fiber length and density without impacting the performance of goats and their offspring. Therefore, melatonin implantation during the cashmere non-growing period (late April and June) is an effective way to increase cashmere yield and improve cashmere characteristics of goats.
Short communication: Concentrate supplementation strategies in ryegrass pasture for productive performance in lambs

Published: February 2018

This study evaluated the effect of two concentrate supplementation strategies on performance, metabolic profile and economic evaluation of suckling lambs and ewes in ryegrass (Lolium multiflorum) pasture. Twenty-seven ewes and 45 lambs were divided into three groups: (1) ryegrass pasture without supplementation - control (CON); (2) CON plus supplemented ewes and lambs at 1% of live weight (SEL), and (3) CON plus creep feeding supplemented lambs at 1% of live weight (CSL). Concentrate use increased (p<0.05) average daily gain (ADG) by 19.95% over CON (21.6 and 18.3% for SEL and CSL, respectively). Concentrate use contributed to minimizing forage quality fluctuation and provided greater ADG stability, mainly when ryegrass nutritional content and digestibility decreased. Blood metabolites profiles did not differ between groups, with exception of phosphorus which was higher for CON than SEL, and calcium which was higher for CSL than CON (p<0.05). Compared to CON, stoking rate values were greater to SEL (p<0.05). Compared to CSL, ewe and total stocking rate were greater (p<0.05) to SEL. Considering the control group as break even feed investment, SEL strategy had a positive economic return, while CSL showed economic losses. Concentrate use increased ADG of lambs and decrease the impact of nutrient quality changes of forage on daily gains, but must be considered that supplemental strategy used could affect negatively economic return.
Debates in Teaching Bioethics

Published: February 2018

In this small scale study in higher education, a good educational practice on the teaching of Bioethics based ontransformative learning and accomplished by debates is presented. The research was carried out in June 2016 at theDepartment of Molecular Biology and Genetics, Democritus University of Thrace, Greece and it includes theassessment of the debating experience by the students participating in the course. The research followed thequalitative method and data was collected by free association through a single question posed to students, askingthem to critically reflect on their debating experience. Content analysis was used for analyzing their responses.Debates seem to be a good practice for teaching Bioethics, since it leads to transformative learning for the futurescientists, as it is highlighted by the students’ views. They strongly state that they were highly interested andmotivated by their participation in debates, an active teaching method that promotes the development of criticalthinking, questioning, processing and presentation of scientific data, as well as the improvement of communicationand cooperation skills. The most significant finding, though, was the critical reflection that young students reachedregarding the subtle, difficult ethical issues of Biosciences.
Efficiency of Authored Mixed Prediction Model with Application to the Labor Market
Authors: Hadas-Dyduch Monika
Published: February 2018

The aim of this article is to evaluate the prediction of time series using a model containing wavelets. The research hypothesis is: “Models that take into account wavelets are an effective tool for predicting employment”. To verify the hypothesis, an original model was devised. The model is based on wavelet analysis with Daubechies wavelets and an exponential alignment model. The exponential alignment model been appropriately modified by the introduction of wavelet functions. The results obtained show that a model that partially includes wavelets is an effective tool in the prediction and analysis of employment
Experimental Behavior of FRP Confined Concrete Cylinder Wrapped by Two Different FRPs
Authors: Rahman Ataur , Mallick Madhobi , Ghosh Shantanu
Published: February 2018

This paper presents the results of experimental investigation on concrete cylinders confined with two different types of fiber reinforced polymer (FRP) sheets, they are: synthetic high strength CFRP composites and composites using natural fiber like Jute. These two FRPs are very much distinct with respect to their strength and recycle properties. Conventional FRPs like CFRP possess superior mechanical strength than natural FRPs, but have got some serious drawbacks such as high density, high cost and poor recycling and non-biodegradable properties. On the other hand, the durability of the natural fibers can be enhanced by mummification of the fibers within the epoxy resin. An experimental study was conducted, where twenty six small scale cylindrical concrete specimens (100 × 200 mm) were subjected to uniaxial compression up o failure and the corresponding stress-strain behaviors were observed. The ultimate failure load and the deformation at peak load were the two important observations. The results demonstrate that a significant increase in the compressive strength can be achieved by confining the concrete with CFRP but both strength and ductility are compromised when concrete is wrapped with JUTE-FRP. However, JUTE-FRP shows reasonably good ductile behavior for the case of low strength concrete and can safely be used for brick masonry column. For low cost strengthening work, JUTE-FRP can be an alternative for low strength concrete and masonry works.

Published: February 2018

Nos estudos sobre bibliometria existe uma tendência de cientistas famosos obterem mais crédito do que cientistas não famosos, por trabalhos similares. O mesmo se aplica a revistas científicas, que obtém mais crédito que outras que divulgam trabalhos de relevância equivalente ou mesmo superior. Esta situação tende a perpetuar uma estrutura de incentivos e políticas que acabam por concentrar a publicação intelectual em poucos periódicos, provocando maior repercussão de suas edições e modificando a forma de se divulgar e produzir ciência. Este texto propõe uma reflexão sobre o processo de melhor qualificar as revistas da área de ciências sociais pelo que hoje se conhece como processo de indexação, explorando a complexa taxonomia sobre o tema.
Porquê Paulo Freire e Amílcar Cabral?
Authors: Cortesão Luiza
Published: February 2018

No presente texto salienta-se a proximidade teórica, ideológica e de formas de acção que se podem identificar em Paulo Freire e Amílcar Cabral. Discute-se em seguida como será possível entender que, no quadro de uma tão grande proximidade, Freire e Cabral tenham tomado posições bem diferentes relativamente ao problema da escolha do português como língua oficial e de aprendizagem. Uma reflexão sobre esta divergência permite, em seguida, explorar a questão da complexidade de factores em jogo, que sempre existe, nas situações de tomadas de decisão.
Uma introdução à pedagogia da correspondência em Paulo Freire
Authors: Coelho Edgar Pereira
Published: February 2018

Este texto discute o interesse de Paulo Freire pelo gênero literário carta e pelo
gênero de escrita carta. O autor desenvolve a partir da tese de doutorado defendida na
FEUSP em 2005, Cartas de Paulo Freire: o diálogo como caminho e pedagogia, que deu
origem à construção de Pedagogia da correspondência: Paulo Freire e a educação por cartas
e livros, publicado em 2011. A abordagem das cartas seguiu a ordem cronológica de sua
elaboração ou recepção, tendo sido distribuídas em três grandes conjuntos: de antes do
exílio, durante o exílio e após o exílio. A análise buscou verificar a centralidade de duas
categorias do pensamento freiriano: (i) o oprimido, como alvo de sua ação pedagógica
e política e (ii) o diálogo como instrumento de desalienação, libertação e promoção do
oprimido. Visa demonstrar que esse gênero de escrita (cartas), esse gênero literário (livros
em forma de carta) constituíam as formas preferidas de Paulo Freire.

Towards Socialist Architecture: Architectural Exhibitions at the Zachęta in the Years 1950–1955
Authors: Czapelski Marek
Published: February 2018

Exhibitions of contemporary designs accompanied by their public criticism and assessment
by a commission were meant to be a tool in implementing Socrealism in Polish architecture –
a process which had been announced in 1949. The First National Exposition of Architectural
Design (OPA, 22 January – 28 February 1951), housed in the Zachęta – National Gallery
of Art building in Warsaw, was one of the most widely advertised events of this kind. Its
discussion exposes the peculiar atmosphere of these events, the strategies of persuasion and
instruction as employed by the organisers in relation to ideological and aesthetic issues, and
the reactions of the architects participating in the debates, who generally tried to avoid the
aggressive tone of the polemic. In addition, the primacy of technocratic economics, which was
later to become one of the key elements of policies concerning the construction industry in
the People’s Republic of Poland, was fi rst revealed at the OPA, if only still in the background.
The exhibition at the Zachęta, treated as a production meeting in progress, was to be
a preparatory stage for a sweeping exhibition that would present an all-inclusive vision of
both historical and contemporary Polish architecture. Such an event accorded with the
universal schemata of rituals of social life structured in keeping in line with Stalinism, but
the path to the First General Exhibition of Architecture in the People’s Republic of Poland
(PWA, 8 March – 22 April 1953) turned out not to be easy. Problems concerning its fi nancing
and venue, as well as the lack of political support, resulted in its opening, in the Zachęta
building, soon after Stalin’s death. In general, the exhibition’s arrangement followed regional
divisions, i.e. both the historical and contemporary material were arranged according to
region. An analysis of this plan reveals that it was profoundly ill-suited to the realities of
producing architecture in the state-owned design offi ces when the emphasis on typicality
was increasing.
The initial stage of the critique of Socrealism is also inseparably linked with the PWA;
the essay appraising the exhibited designs as delivered at the First National Council of
Architects in April 1953 must be considered the fi rst text of this kind.
Both the OPA and the PWA are, above all, reminders of the practice of institutional
coercion and of the ideological approach to history that were typical of Stalinism. At the
same time, however, it should not be forgotten that the exhibition of 1953 resulted in the
publication of a series of valuable publications concerning history and art, while the Regional
Architectural Shows, instituted in order to select designs to be exhibited at the PWA,
evolved into recurring events which in some centres are still organised today.
“The War Brought Us Close and the Peace Will Not Divide Us”: Exhibitions of Art from Czechoslovakia in Warsaw in the Late 1940s
Authors: Skarupsky Petra
Published: February 2018

In his book Awangarda w cieniu Jałty (In the Shadow of Yalta: Art and the Avant-garde in
Eastern Europe, 1945–1989), Piotr Piotrowski mentioned that Polish and Czechoslovakian
artists were not working in mutual isolation and that they had opportunities to meet, for
instance at the Arguments 1962 exhibition in Warsaw in 1962. The extent, nature and
intensity of artistic contacts between Poland and Czechoslovakia during their coexistence
within the Eastern bloc still remain valid research problems. The archives of the National
Museum in Warsaw and the Zachęta – National Gallery of Art which I have investigated
yield information on thirty-fi ve exhibitions of art produced in Czechoslovakia that took
place in Warsaw in the period of the People’s Republic of Poland. The current essay focuses
on exhibitions organised in the late 1940s. The issue of offi cial cultural cooperation between
Poland and Czechoslovakia was regulated as early as in the fi rst years after the war. Institutions
intended to promote the culture of one country in the other one and associations
for international cooperation were established soon after. As early as in 1946, the National
Museum in Warsaw hosted an exhibition entitled Czechoslovakia 1939–1945. In 1947 the
same museum showed Contemporary Czechoslovakian Graphic Art. A few months after “Victorious
February”, i.e. the coup d’état carried out by the Communists in Czechoslovakia
in early 1948, the Young Czechoslovakian Art exhibition opened at the Young Artists and
Scientists’ Club, a Warsaw gallery supervised by Marian Bogusz. It showed the works of
leading artists of the post-war avant-garde, and their authors were invited to the vernissage.
Nine artists participated in both exhibitions, i.e. at the National Museum and at the
Young Artists and Scientists’ Club. A critical analysis of art produced in one country of
the Eastern bloc as exhibited in another country of that bloc enables an art historian to
outline a section of the complex history of artistic life. Archival research yields new valuable
materials that make it impossible to reduce the narration to a simple opposition
contrasting the avant-garde with offi cial institutions.
The Post-War History of Pictorialism as Exemplifi ed by Exhibitions at the Zachęta and the Kordegarda (1953–1970)
Authors: Kobylińska-Bunsch Weronika
Published: February 2018

Existing academic works examining Polish artistic photography in the 1950s and 1960s are
most often based on an analysis of the debates taking place within professional circles and
the views of specifi c artists as expressed in the specialist periodicals that were published
at that time. Such diagnoses are frequently based on a single and very particular source,
namely the monthly magazine Fotografi a. The pages of this periodical project an image of
an artistic society enjoying a relatively high degree of autonomy. The present study represents
a different research approach, inspired e.g. by the works of Bruce Altshuler and
Kenneth Luckhurst, who postulated the re-orientation of art history away from biographical
works focused on the individual subject towards a discipline understood as the history
of exhibitions. Following the course set by these scholars, one may come to the conclusion
that an analysis of the place which photography held in the offi cial exhibition strategy
implemented in the 1950s and 1960s in the prestigious Warsaw galleries of the Kordegarda
and the Central Bureau of Art Exhibitions (CBWA) may provide an interesting and new
contribution to the current state of research. A study based on an examination of the
history of exhibitions may help to answer the question whether all forms of photography
were equally approved by the authorities at a time when the rules of the cultural policy
of the People’s Republic of Poland became more lenient. It also makes it possible to evaluate
the degree to which autonomy and heterogeneity (features which may be associated
with the magazine Fotografi a) were legitimised through presentation in a state-owned,
politicised public space. Conducted from the perspective of exhibition history, the analysis
presented herein makes an important shift in the signifi cance of Pictorialism – from a topic
on the margins of academic interest to a harbinger of modernity, and thus a central subject
in the discourse on Polish photography in the post-war period. Rather surprisingly, it
appears to be the slogan that legitimised the more innovative and modern forms of photographic
art in the offi cial contexts of the day.
Exhibitions of Sculpture as a Sign of the Spatial Shift: From Spring Salon to Sculpture in the Garden
Authors: Leśniewska Anna Maria
Published: February 2018

A selection of exhibitions of sculpture held between the years 1946 and 1957 illustrates
the formal transformations and diversity of methods of exhibiting sculpted forms as identifi
ed through their manner of cooperating with space. The experiments, which commenced
during the First Exhibition of Modern Art (1948) and were later creatively developed at
the Krzywe Koło and Zachęta galleries, were based on ideas that had been formulated by
K. Kobro and W. Strzemiński in Kompozycja przestrzeni. Obliczenia rytmu-czasoprzestrzennego
(1931), produce a diversifi ed picture of intense formal exploration of sculpture, with the
category of “space” emerging as a crucial part of the research perspective. The integrated
gallery space and the setting for a work of art – which during the Sculpture in the Garden
show (1957) included outdoor space – defi ned a trend that was moving towards the concept
of an installation. Exhibitions indirectly connected with sculpture, e.g. Studium
przestrzeni (1957), were used as research instruments in the process of extending the boundaries
of sculptural forms to include their reaching into space.

The paper dwells on application of a vertical take-off/landing aerial observation drone that is equipped with a video camera to localise on testing range places of falling for experimental 120 mm inert mortar projectiles having head percussion fuse and filled with a black powder charge. The drone was flying at the height of 50-80 m and filming with the rate of 25 pictures per second when observing an area of predicted projectiles falls. A typical sequence of pictures taken by the drone camera and showing the terminal fragment of projectile trajectory with effects of hitting into the ground is presented. The falling sites of all (ten) fired projectiles were identified. Application of the drone for the range tests has also enhanced the level of their safety and allowed the monitoring of a fire threat.
Social Pedagogical Reflections in a Danish Version – Challenging an Individual Perspective in the Modern World
Authors: Nørgaard Britta
Published: February 2018

particularly over the last 40 years. In my way of understanding social pedagogy I draw on multiple sources of inspiration. Theoretically, I am inspired by German social philosophy and German pedagogical traditions. In this article I want to show how some of these inspirations could be transformed into practice in a way that both the community and the individual benefit. Drawing upon three different conceptual models of social pedagogy, I will discuss that the pedagogical approach in combination with a social and philosophical approach have a broader ethical and human potential than former models. Social pedagogical work is based on many different values related to attitudes among professionals, related to community and community building, and related to relations and social interaction. This calls for reflections on the relation between the individual and the group, on concepts of the ‘other’, on education and professionalism.
What is the Swedish Interpretation of Social Pedagogy. A Literature Review
Authors: Högström Mats
Published: February 2018

The concept of social pedagogy can be studied from different perspectives and with diverse foci. According to Eriksson & Markström (2000) there are three main ways to study the phenomenon of social pedagogy: as an area of expertise, academic subject or professional action. In this article the main focus is on social pedagogy as an area of expertise or in other words its knowledge field and territory. Alternatively, according to Brante (2003) the core, the periphery and limits of social pedagogy.
The Impact of Falling Crude Oil Price on Financial Markets of Advanced East Asian Countries
Authors: Sultonov Mirzosaid
Published: February 2018

We analysed the response of the financial markets of advanced East Asian countries to the significant decline in crude oil price which occurred in 2014. We used daily logarithmic returns of the representative exchange rates of national currencies and stock prices from 1 January, 2013 to 31 December, 2015. The empirical findings showed a significant change in both the dynamic correlation of exchange rates and stock prices and the causality relationship between the commodity, foreign exchange and stock markets during the period of declining crude oil price and instability. This paper highlights the response of the financial markets of advanced East Asian economies to a sharp decline in and instability of crude oil price, thereby contributing to the empirical literature and providing guidance for investment portfolio management.
The Effect of Tax System on Shareholder Decisions when Choosing a Accounting Principles
Authors: Hashimy Hisham Noori Hussain AL-
Published: February 2018

This paper aims to identify the factors that affect the decisions of the tax system to choose the accounting principles in Iraqi companies. The focus is on managing perceptions of the impact of the tax system on cost and the views of stakeholders in accounting principles. In a Real data, we pick Final budgets end of the year data of the 2 most important companies in Iraq, and the statement of their views on the impact of the figures reported by stakeholders in the companies and how to track companies specific targets linked to profit. According to the participants in the real data accounting figures and the impact of corporate perceptions of stakeholders and selection of accounting principles, tracking corporate goals for profit is not consistent with the objective of minimizing the tax system for companies.Despite taking some measures to reduce response bias, one cannot rule out the possibility of introducing some bias in the responses. It will provide more empirical investigations based on annual reports for more information on evidence of factors that affect the reporting policies of the companies. This study helps researchers to determine the tax systems that determine the accounting principles for companies operating in countries with similar environment to those in Iraq. In addition, the results of this study can facilitate professionals who are doing an international financial analysis. The results of this study can contribute to explain the contributions of Iraqi company's decisions. Given that the Iraqi tax system is similar to that prevailing in many neighboring Gulf countries, the Gulf States; this study can provide an insight into the factors affecting the financial reporting of companies operating in these countries.

FIRST-PRINCIPLES SIMULATION OF THE CERIUM TRIFLUORIDE INFRARED SPECTRUM BEYOND THE BORN–OPPENHEIMER APPROXIMATION
Authors: Vasilyev Oleg A. , Solomonik Viktor G.
Published: February 2018

The group-theoretical analysis was carried out to derive a spin-vibronic model Hamiltonian and a diabatic dipole moment operator for a cerium trihalide molecule, CeX3. The model comprises seven lowest-lying 4f1 electronic states coupled by six vibrational modes, (A2'' + E' + E'' + A1' + A2') × (a1' + a2'' + e' + e'), with an accounting for spin-orbit coupling. Multimode potential energy surfaces have been calculated for the CeF3 molecule at the multi-reference singles and doubles configuration interaction level of theory corrected for quadruple excitations, MRCISD+Q, and dipole moment surfaces at the MRCISD level. A hybrid approach employing a quasi-diabatization technique was utilized to determine the relevant model parameters up to forth order in power series of the Q1(a1'), Q3(e'), Q4(e') normal coordinates, and eighth order of the Q2(a2'') out-of-plane bending normal coordinate. Spin-orbit coupling was taken into account through zero-order, with the respective constants obtained from matrix elements of the Breit–Pauli operator in the basis of states generated at the MRCISD level. The spin-vibronic Hamiltonian and dipole moment operator obtained in this way has been utilized in the variational calculations to simulate the infrared absorption spectrum of CeF3. The resulting spectrum features a complex structure owing to an intricate interplay of the vibronic (Jahn–Teller and pseudo-Jahn–Teller) and spin-orbit coupling effects, and hence cannot be explained within the conventional Born–Oppenheimer (BO) approximation. The strongest absorption appearing in the simulated spectrum at about 500 cm–1, mostly associated with the Q3(e') stretching mode, is split into two bands by about 3 cm–1. This finding is in full agreement with the CeF3 matrix isolation infrared spectroscopy data. On the whole, the results of the calculations clearly indicate the vibronic rather than vibrational origin of the spectral bands, including the bands in the low-frequency region of the spectrum, and thus show the fallacy of the generally accepted assignment of the bands observed in the experiment to the fundamental vibrational transitions of the molecule made on the assumption of the admissibility of describing this within the Born–Oppenheimer approximation. The new assignment of the experimental IR spectrum of CeF3 is proposed.Forcitation:Vasilyev O.A., Solomonik V.G.

La recherche qualitative critique : la synergie des approches inductives et des approches critiques en recherche sociale
Authors: Caron Caroline
Published: February 2018

Les approches inductives et les approches critiques sont des termes génériques commodes qui n’ont cependant pas de signification univoque en sciences sociales. Les rapprocher présente donc un risque de confusion. Cet article théorique a pour but de problématiser leurs rapports en apportant une clarification terminologique et une remise en cause de leur prétendue opposition. La thèse défendue soutient qu’aucune antinomie constitutive ne prévient un rapprochement entre les approches inductives et critiques, mais que cette compatibilité ne va pas de soi pour autant. Les deux approches n’interviennent pas sur les mêmes éléments du processus de recherche et la posture épistémologique retenue leur confère également des inclinaisons variables. Dans cet article, le courant critique de la recherche qualitative est désigné comme un territoire propice à la synergie des approches inductives et critiques, car il permet notamment d’élargir le cadre courant des discussions méthodologiques en sciences sociales.
Une phénoménologie dialectique à la fois critique et compréhensive
Authors: Dumais Fabien
Published: February 2018

Cet article propose un regard croisé de la phénoménologie dialectique du penseur critique Michel Freitag et du constructivisme social de Peter Berger et Thomas Luckmann. En soutenant que le procès dialectique de production de sens est phénoménologiquement constitutif de la réalité, il devient possible de penser la coexistence des démarches critique et compréhensive pour les recherches en sciences humaines et sociales, et ainsi dépasser de faux dilemmes par l’explicitation de l’interdépendance de ces pôles.

Las representaciones del Estado del Bienestar y la formación ciudadana. Un estudio de caso
Authors: Asensi Silvestre Elvira
Published: February 2018

El objetivo de esta investigación es averiguar cuáles son las representaciones previas de los estudiantes universitarios sobre el Estado de Bienestar. A partir de esta temática se indaga en la concepción que tienen de ciudadanía y se muestra cómo problematizar y pensar históricamente un tema social de actualidad. Lo investigamos utilizando diferentes instrumentos como cuestionarios de ideas previas y grupos de discusión. Los resultados permiten concluir que el alumnado carece de la visión histórica del Estado del Bienestar pero que a medida que se reflexiona sobre su evolución histórica y su vigencia hoy en día la percepción cambia hacia una mayor concienciación sobre el modelo de ciudadanía crítica y éticamente responsable que se quiere promover.
