Time series analysis for determining ecologically acceptable Cu concentration from species sensitivity distribution with biotic ligand models in soil pore water
Authors: Jeong Buyun , An Jinsung , Nam Kyoungphile
Published: April 2020

A site-specific, ecologically acceptable concentration of Cu in soil pore water was determined with four trophic levels of soil-residing organisms. Specifically, soil pore water was periodically collected from a site contaminated with heavy metals using in-situ samplers. Dissolved Cu concentration, Ca2+, Mg2+, Na+, K+, Cl-, SO42-, NO3-, dissolved organic carbon, pH, and temperature were analyzed to derive a half-maximal effective concentration of Cu (EC50[Cu]T) using a biotic ligand model (BLM). The BLM parameters, such as binding constants (logKXBL) and the fraction of biotic ligand sites occupied by Cu ions (f), were adapted from previous studies. The EC50{Cu2+,} values were used to construct a species sensitivity distribution (SSD) curve from which the hazardous concentration, protecting 95% of the soil-residing organisms (HC5), was determined. Using ten BLM-based acceptable concentrations of Cu obtained by combining BLM and SSD, time series analysis was conducted with the fixed monitoring benchmark method to obtain maximum Cu concentration as an endpoint exhibiting no-adverse-effect which was found to be 0.084 mg/L of Cu in soil pore water at the test site. This study provides a systematic tool for determining an ecologically acceptable concentration of Cu in the soil by incorporating soil pore water chemistry and time series analysis.

Fixed poin sets in digital topology, 1
Authors: Boxer Laurence , Staecker P. Christopher
Published: April 2020

In this paper, we examine some properties of the fixed point set of a digitally continuous function. The digital setting requires new methods that are not analogous to those of classical topological fixed point theory, and we obtain results that often differ greatly from standard results in classical topology.

We introduce several measures related to fixed points for continuous self-maps on digital images, and study their properties. Perhaps the most important of these is the fixed point spectrum F(X) of a digital image: that is, the set of all numbers that can appear as the number of fixed points for some continuous self-map. We give a complete computation of F(Cn) where Cn is the digital cycle of n points. For other digital images, we show that, if X has at least 4 points, then F(X) always contains the numbers 0, 1, 2, 3, and the cardinality of X. We give several examples, including Cn, in which F(X) does not equal {0, 1, . . . , #X}.

We examine how fixed point sets are affected by rigidity, retraction, deformation retraction, and the formation of wedges and Cartesian products. We also study how fixed point sets in digital images can be arranged; e.g., for some digital images the fixed point set is always connected.

Abstract. Dissolved iron (dFe) is essential for multiple biogeochemical
reactions in oceans, such as photosynthesis, respiration and nitrogen
fixation. Currently, large uncertainties remain regarding the input of
riverine dFe into coastal oceans, especially in tropical rivers in southeastern
Asia. In the present study, the concentrations of dFe and distribution
patterns of dFe were determined along the salinity gradient in the Rajang
River and three blackwater rivers that drain from peatlands, including the
Maludam River, the Sebuyau River and the Simunjan River. In the Rajang
River, the dFe concentration in freshwater samples (salinity <1 PSU – practical salinity units) in
the wet season (March 2017) was higher than that in the dry season (August
2016), which might be related to the resuspension of sediment particles and
soil erosion from cropland. In the Rajang estuary, an intense removal of dFe
in low-salinity waters (salinity <15 PSU) was observed, which was likely
due to salt-induced flocculation and absorption of dFe onto suspended
particulate matter (SPM). However, increases in the dFe concentration in the
wet season were also found, which may be related to dFe desorption from SPM
and the influences of agricultural activities. In the blackwater rivers, the
dFe concentration reached 44.2 µmol L−1, indicating a strong
contribution to the dFe budget from peatland leaching. The dFe flux derived
from the Rajang estuary to the South China Sea was estimated to be
6.4±2.3×105 kg yr−1. For blackwater rivers, the
dFe flux was approximately 1.1±0.5×105 kg yr−1 in the Maludam River. Anthropogenic activities may play an important role
in the dFe yield, such as in the Serendeng tributary of the Rajang River and
Simunjan River, where intensive oil palm plantations were observed.
CO2, CH4 and N2O fluxes along an altitudinal gradient in the northern Ecuadorean Andes: N2O consumption at higher altitudes

Published: April 2020

Abstract. Tropical forest soils are an important contributor to the global greenhouse (GHG) budget and understanding this ecosystem function is of vital importance for future global change and climate research. In this study, we quantified soil fluxes of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) of four tropical forest sites located along an altitudinal gradient from 400 to 3010 m a.s.l. on the western flanks of the Andes in northern Ecuador. We assessed the physicochemical soil properties influencing these fluxes during the dry season, as well as the bulk isotopic signature of N2O. The CO2 fluxes ranged between 55.3±12.1 and 137.6 ± 32.8 mg C m−2 h−1, with the highest and lowest emissions at the highest strata, at 3010 and 2200 m a.s.l., respectively. CH4 fluxes at all sites exhibited a net consumption of atmospheric CH4 and ranged between −74.4 ± 25.0 µg C m−2 h−1 at 2200 m a.s.l. to −46.7 ± 14.7 µg C m−2 h−1 at 3010 m a.s.l. Net fluxes of N2O ranged between −5.1 ± 1.9 and 13.2 ± 31.3 µg N m−2 h−1, with a marked net sink at 2200 and 3010 m a.s.l., whereas a net source at 400 m. pHwater and nitrate (NO3−) content at 5 cm depth were able to explain 83 % of the observed temporal (daily measurements) and spatial (four forest sites) variability of the CO2 fluxes; indicating that an increase in pHwater and NO3− contents lead to an increase in CO2 emissions. For CH4 fluxes, it was not possible to obtain a statistically significant model to identify the physicochemical soil drivers responsible for the CH4 consumption. For N2O, bulk density and pHwater at 5 cm depth were negatively correlated to the N2O fluxes, but able to explain only 36 % of the temporal and spatial variability. In addition, the bulk isotope N2O data confirmed that N2O reduction was at the basis of the observed net soil sink at higher altitudes. Finally, the soil GHG budget showed that all studied soils were net sources of GHG's. CO2 emissions represented the largest component of the total soil GHG budget, CH4 consumption was quite consistent along the elevation gradient, whereas N2O was highly variable, and the transition from sources to net sinks at higher altitudes represented the biggest change in the net GHG balance. Overall, for non-CO2 GHGs, we noticed a transition from a net source to a net GHG sink along altitude.
On the validation of K-index values at Italian geomagnetic observatories
Authors: Regi Mauro , Bagiacchi Paolo , Di Mauro Domenico , Lepidi Stefania , Cafarella Lili
Published: April 2020

Abstract. The local K index and the consequent global Kp index are well-established 3 h range indices used to characterize geomagnetic
activity. The K index is one of the parameters that INTERMAGNET observatories
can provide, and it has been widely used for several decades, although many other
activity indices have been proposed in the meanwhile. The method for
determining the K values has to be the same for all observatories.
The INTERMAGNET consortium recommends the use of one of the four methods endorsed
by the International Service of Geomagnetic Indices (ISGI) in close
cooperation and agreement with the ad hoc working group of the International
Association of Geomagnetism and Aeronomy (IAGA). INTERMAGNET provides the
software code KASM, designed for an automatic calculation of the K index
according to the adaptive smoothed method. K values should be independent of
the local dynamic response, and therefore for their determination each
observatory has its own specific scale regulated by the L9 lower limit,
which represents the main input parameter for KASM. The determination of an
appropriate L9 value for any geomagnetic observatory is then fundamental. In
this work we statistically analyze the K values estimated by means of KASM
code for the Italian geomagnetic observatories of Duronia (corrected
geomagnetic latitude λ∼36∘ N) and
Lampedusa (λ∼28∘ N) by comparing them with
the German observatories of Wingst and Niemegk. Our comparative analysis is
finalized to establish the best estimation of the L9 lower limit for these
two stations. A comparison of L9 lower limits found for the Italian
observatories with results from a previous empirical method was also applied
and used to verify the consistency and reliability of our outcomes.
Evaluation of soil moisture from CCAM-CABLE simulation, satellite-based models estimates and satellite observations: a case study of Skukuza and Malopeni flux towers
Authors: Khosa Floyd Vukosi , Mateyisi Mohau Jacob , van der Merwe Martina Reynita , Feig Gregor Timothy , Engelbrecht Francois Alwyn , Savage Michael John
Published: April 2020

Abstract. Reliable estimates of daily, monthly and seasonal soil moisture are useful
in a variety of disciplines. The availability of continuous in situ soil
moisture observations in southern Africa barely exists; hence, process-based
simulation model outputs are a valuable source of climate information,
needed for guiding farming practices and policy interventions at various
spatio-temporal scales. The aim of this study is to evaluate soil moisture
outputs from simulated and satellite-based soil moisture products, and to
compare modelled soil moisture across different landscapes. The simulation
model consists of a global circulation model known as the conformal-cubic
atmospheric model (CCAM), coupled with the CSIRO Atmosphere Biosphere Land
Exchange model (CABLE). The satellite-based soil moisture data products
include satellite observations from the European Space Agency (ESA) and
satellite-observation-based model estimates from the Global Land Evaporation
Amsterdam Model (GLEAM). The evaluation is done for both the surface (0–10 cm) and root zone (10–100 cm) using in situ soil moisture measurements
collected from two study sites. The results indicate that both the
simulation- and satellite-derived models produce outputs that are higher
in magnitude range compared to in situ soil moisture observations at the two
study sites, especially at the surface. The correlation coefficient ranges
from 0.7 to 0.8 (at the root zone) and 0.7 to 0.9 (at the surface),
suggesting that models mostly are in an acceptable phase agreement at the
surface than at the root zone, and this was further confirmed by the root mean
squared error and the standard deviation values. The models mostly show a
bias towards overestimation of the observed soil moisture at both the
surface and root zone, with the CCAM-CABLE showing the least bias. An
analysis evaluating phase agreement using the cross-wavelet analysis has
shown that, despite the models' outputs being in phase with the in situ
observations, there are time lags in some instances. An analysis of soil
moisture mutual information (MI) between CCAM-CABLE and the GLEAM models has
successfully revealed that both the simulation and model estimates have a
high MI at the root zone as opposed to the surface. The MI mostly ranges
between 0.5 and 1.5 at both the surface and root zone. The MI is
predominantly high for low-lying relative to high-lying areas.

Published: April 2020

Abstract. An integrated modeling approach for simulating flood events is presented in the current study. An advanced flood forecasting model, which is based on the coupling of hydrological and atmospheric components, was used for a twofold objective: first to investigate the potential of a coupled hydrometeorological model to be used for flood forecasting at two drainage basins in the area of Attica (Greece) and second to investigate the influence of the use of the coupled hydrometeorological model on the improvement of the precipitation forecast skill. For this reason, we used precipitation and hydrometric in-situ data for 7 events at two selected drainage regions of Attica. The simulations were carried out with WRF-Hydro model, which is an enhanced version of the Weather Research and Forecasting (WRF) model complemented with the feedback of terrestrial hydrology on the atmosphere, where surface and subsurface runoff were computed at a fine resolution grid of 95 m. Results showed that WRF-Hydro is capable to produce the observed discharge after the adequate calibration method at the studied basins. Besides, the WRF-Hydro has the tendency to slightly improve the simulated precipitation in comparison to the simulated precipitation produced the atmospheric only version of the model. These outcomes provide confidence that the model configuration is robust and, thus, can be used for flood research and operational forecasting purposes in the area of Attica.
Extractive stripping voltammetry at a glassy carbon paste electrode for analysis of cow's milk and cream
Authors: Jashari Granit , Frühbauerová Michaela , Sýs Milan , Červenka Libor
Published: April 2020

In this paper, a procedure based on extractive accumulation of milk fat globules (MFGs) into a pasting liquid (lipophilic binder) of glassy carbon paste electrode (GCPE) with subsequent electrochemical detection by square-wave voltammetry (SWV) in 0.1 mol L-1 Britton-Robinson buffer of pH 4.0 has been tested to find out whether it can be utilized as a simple screening analytical method for cow's milk and cream nutrition control. Since there is assumption that the necessary alkaline hydrolysis of cow's milk and subsequent extraction of lipophilic vitamins into an organic solvent could be avoided, several GCPEs differing in type (atactic polypropylene, paraffin oil, paraffin wax, silicone oil, and vaseline) and content (5, 10, 15, 20, and 25%; w/w) of pasting liquid used were tested as part of complex optimization. The obtained results show that MFGs contain predominantly vitamin A (carotenoids and retinoids), especially all-trans-retinol, which could serve as significant marker of the fat content. However, their individual forms were not possible to distinguish due to the considerable anodic peak broadening (overlapping).

Published: April 2020

Aim of study: To investigate the impact of Croatia’s accession to the EU on its agricultural sector, its market outlook and the EU’s key agricultural products up to 2030.Area of study: Croatia and European Union member statesMaterial and methods: Comparative approach was used in order to identify similarities of the changes that took place when other Central and Eastern European Countries (CEEC) acceded to the EU (results of previously conducted research) with the changes that happened in Croatia (historical data between 2010 and 2016). The second approach involved the AGMEMOD partial equilibrium model, which has been used as a comprehensive tool to model the complex outlook of Croatian agricultural markets. The results of the Croatian outlook were compared to the EU’s AGMEMOD outlook results in order to identify future trends in key agricultural market development (production, yield and net trade) and whether these newly established trends were comparable with EU trends.Main results: The changes that took place in the Croatian agricultural sector during and after the EU accession period are not significantly different from the trends and changes observed in other Central and Eastern EU member states. Similarities can especially be found in neighbouring CEEC countries (Hungary and Slovenia), which kept their producer prices close to EU levels prior to accession. Furthermore, the results indicate a similarity with CEEC trends in terms of the strengthening of crop production compared to livestock.Research highlights: Positive effects of EU integration on the Croatian agricultural sector took place after a few years of adjustment. Simulations of future market developments indicate many similarities between Croatia and EU 13 member states.

Published: April 2020

Aim of study: We investigated water evaporation of the soil surface and the soil water distribution under different mulching techniques using subsurface drip irrigation (SDI) system.Area of study: The experiment was conducted at the Agricultural Research and Experimental Farm in Dirab, Riyadh, Saudi Arabia, locating 24.4195° N, 46.65° E, and 552 m altitude.Material and methods: The two types of soil surface mulching were black plastic film (BPF) and palm tree waste (PTW), with no mulching (NM) as control. The two drip line depths from the soil surface (DL) were 15 cm and 25 cm, and surface drip irrigation (DI) was the control.Main results: In SDI, the use of BPF or PTW mulching resulted in enhanced water retention capacity of the soil and an approximately 6% water saving, compared with NM. The amounts of water saved at DL of 15 cm (19-24 mm) were greater than those at DL of 25 cm (15-20 mm), whereas the DI used the highest amount of applied water. The distribution of soil water content for BPF and PTW were found to be more uniform than NM.Research highlights: It is advised to mulch the soil with PTW due to lower costs and through a DL of 15 cm.
Categorization of Boranes Into Clan Series
Authors: Kiremire Enos Masheija Rwantale , Lule Ivan
Published: April 2020

Boranes, despite their instability in nature, can be regarded as hydrocarbon relatives since a [BH] fragment corresponds to a carbon [C] skeletal element in terms of the number of valence electrons. The borane formula which can be expressed as BnHm usually appears in such a way that when (n) is even, then (m) is even and when (n) is odd, (m) is odd as well. Through the study of cluster series, it appears that the cluster number K which represents skeletal linkages is usually a whole number. This inherent characteristic confers unique order within borane clusters with nodal connectivity of 5 and the polyhedral nature of the borane clusters. The orderliness of the borane clusters is reflected by the ease of their categorization into clan series and their readily constructed geometrical isomeric structures. The cluster valence electrons can easily be calculated using one of the six recently discovered fundamental equations.

Published: April 2020

The objective of this research was to analyze the effect of gamification on intention to use online training from the partial validation of the UTAUT model for qualification of members and servers of the Regional Labor Court of the 2nd Region (TRT-2). The study analyzed the relationship between constructs performance expectancy, effort expectancy, facilitating conditions, and familiarity with the intention to use gaming in distance media.  This was conducted through an empirical application, which used the Structural Equation Modeling (SEM) for data analysis. The research was a single cross-sectional survey, carried out with TRT-2 members and servers who participated in the distance-feeding course ‘Healthy Living’ in 2015. Of the four hypotheses, only familiarity (F) was not significant as it did not serve as a behavioral intentions (BI) predictor of gamification for distance learning courses. Some explanations for such phenomenon may be career promotion and additional qualifications, learning by doing and sample size. The results confirmed that most hypotheses have a high statistical significance of the structural paths and have demonstrated that the model proposed in this study is consistent and can be applied in future studies with appropriate adjustments.

Authors: Silva José Kennedy Lopes , Siena Osmar
Published: April 2020

Environmental organizations actively take part in the proposition of strategies, studies and environmental practices that aim at reducing the environmental degradation of the planet. These organizations have conceptions and commitments that guide their actions. The objective of the research that led to this article was to understand the environmental conceptions and the ideological commitments that guide the actions and the management of the environmental organizations. The research focused on three environmental organizations, two located in the state of Mato Grosso and one in the state of Rondônia, all of them belonging to the Brazilian Legal Amazon region. A qualitative research with multiple case study was carried out. Participant observation, semi-structured interviews and documentary analysis were used as strategies. Several environmental conceptions that influence the performance and management of organizations were identified, with a greater presence of the socio-environmentalist and of the environmental justice conceptions. However, the latter is not discussed strategically. Regarding the ideological commitments, the eco-socialist vision is the one that seems to have more influence over organizations.

Published: April 2020

Considering the benefits of investing in foreign stocks, and, in contrast, the occurrence of the home bias phenomenon, this research aimed to analyze the relationship between home bias and performance. The sample of the study is comprised of 488 Brazilian mutual funds. We employed a multivariate regression model to analyze the relationship among the variables. As a performance proxy, we adopted the Sharpe index for the period from January, 2010 to December, 2015. The average level of investments in foreign stocks was the independent variable of interest. The main results indicated that home bias seems to be costly and probably it occurs due behavioral biases. In a second regression model, we also found that the mutual funds designed for qualified investors and those requiring higher levels of minimum value for investment tend to present lower levels of home bias.

Published: April 2020

The changes that have taken place in recent years in Brazil have affected the structure of families, allowing children to play an important role in the purchasing decisions of the family group. Thus, the children's public has become a significant influence on the acquisition of goods and products, as well as the brands and models acquired by the families. Faced with this reality, the present study sought to identify the influence of the child on the family consumption decision in shopping at supermarkets in the city of Sant'Ana do Livramento / RS. For that, a quantitative approach was carried out, with descriptive character and Survey method. The data were collected with 115 parents of children aged between two and twelve years, with the collection of supermarkets and state schools in the city of Sant'Ana do Livramento. The results show that the children accompany their parents in shopping at the supermarket and participate in them, influencing the acquisition of certain products. In the same way, one can perceive the influence of the media in deciding what the children want to consume.

In 2018, the American singer Lady Gaga celebrates a decade of the release of her first pop album, The Fame. Ten years ago, the world through a series of more successful and awarded songs of the new generation, capable of breaking records in the disputed music industry. As every product has its lifecycle, Lady Gaga's music has come to decline, but the singer has been able to react and maintain her competitive edge. In the ups and downs of the market, Lady Gaga is a strong analogy of product changes, amalgamating itself to revitalize her sector, articulating the internal activities, repositioning herself; an image of the challenge that is accomplished in reinventing herself. Thus, from this historical analysis in which the organisation is viewed as a persona, this work reflects on survival strategies in an environment of rapid change and that requires at the same time, identity and constant adaptation. The approach is qualitative and descriptive, based on real cases of the corporate context that work as parallel to the storytelling created from the Gaga case. As a result, a conceptual model on business strategy in competitive environments is presented, which aggregates different schools of thought of the organizational strategy and that can be verified in future researches.

The objective of this article is to analyze the content of environmental disclosure of industrial companies participating in the Corporate Sustainability Index (ISE) of the Brazilian Stock Exchange (B3) from 2009 to 2016, based on the Stakeholders’ Theory perspective. We adopt a descriptive approach, with qualitative and quantitative analysis of secondary data that we analyze by means of content analysis and statistical techniques. The data collection took place from the institutional site of each organization to obtain the Annual Sustainability Reports. The reports went through text analysis, which resulted in an inventory of words related to the concept of sustainability. The results indicate that the analyzed companies have  similarities with regard to the content disclosed in the Annual Sustainability Reports. Such similarities occur in spite of the fact that companies operate in different industrial segments (petrochemical, food, wood, pulp and paper products and personal use products) and probably come from a homogeneous perception of the segments interested in the information, which would be in reduced number. Although the surveyed companies operate in different segments, they are subject to similar pressures by stakeholders and that imposes an apparent homogeneity to their reports.

Published: April 2020

Sustainable Innovation is strategically associated with Corporate Social Responsibility (CSR), integrating the economic, social and environmental dimensions in a joint and integrated manner. As a way of verifying this association and its implications for business performance (BP), the models of Maturity in Sustainable Innovation (MSI) and Maturity of Corporate Social Responsibility (MCSR) allow us to identify how companies are evolving in a certain area and, from there, create business value and gain competitive advantage. Based on Resource-Based Theory, the present study examines the influence of MSI on MCSR and the mediator effect of MCSR on the relationship between MSI and BP. The analysis is based on Structural Equations Modeling, considering a sample of 58 companies based in the Amazon region, Brazil. The results indicate a strong relationship between MSI and MCSR; that MCSR positively influences BP; and that MCSR exerts a positive mediator effect on the relationship between MSI and BP. These results allow us to advance our strategy studies, providing mechanisms for managing sustainability-related practices as possible sources for analyzing value generation and promoting competitive advantages for companies.

Nowadays companies are under pressure from the globalized market to have a sustainable, quality and value added attitude. The micro-enterprises along with the ones of small size are the most representative in the world, highlighting the importance of their role in the society according to the Brazilian Support Service for Micro and Small Enterprises - SEBRAE (2017). Therefore, this research aims to analyze the sustainable practices used by microenterprises from the industrial region of the central state of Rio Grande do Sul. To do so, the nature of research is classified as qualitative and quantitative, exploratory, and the methodology used was the multiple case study. The research was applied in five micro-companies of the industrial sector that make up the Metal Centro cluster, through semi-structured interviews with the managers. The obtained data were processed in the software Sphinx Léxica - v5, to aid in the interpretation, after analyzing the quantitative data, the content analysis of the results obtained with the theory approached was performed. .From the research it was evidenced that the micro companies have basic attitudes about sustainable practices, that is, they use those methodologies that are within their reach, because the practices that require a greater degree of dedication, commitment and investment, are not executed. Given this, the results achieved in this research indicate that the development of sustainable practices is not the priority in the business of companies, except in cases of legal norms or government requirements.

Este artigo tem o intuito de socializar, como recorte de um projeto de tese, a reflexão sobre a criação e estruturação de disposições inseridas na modalidade de dança de salão desde a sua criação, a manutenção dessas disposições pelos processos formativos e de aprendizagem e de que forma esses elementos codificados são responsáveis por “moldar” os corpos dos sujeitos envolvidos nessa prática, reforçando, dessa forma, conceitos heteronormativos, binários e sexistas. Para essa reflexão, são abordados, a trajetória da dança de salão em seus processos civilizatórios, em articulação com os aportes teóricos de Pierre Bourdieu sobre corpo social e o capital corporal, com o objetivo de identificar como o corpo, como um agente social portador de um habitus, transita no campo em que está inserido e se relaciona com os fatores culturais e temporais. Na pretensão de abrirmos uma discussão sobre o quanto a manutenção desses conceitos pode significar uma violência simbólica e uma relação de poder, impossibilitando que a dança de salão seja uma atividade verdadeiramente aberta a todos.

Published: April 2020

Neste artigo propomos produzir e analisar narrativas sobre experiências de escrita no ensino superior universitário, explorando e ampliando práticas de escrita narrativa dialógica. Realizada a oito mãos, a narrativa que se constrói e, subsequentemente, se procura analisar é submetida a uma reflexão contínua, polivalente, que exprime uma procura metodológica de exploração e ampliação das possibilidades da escrita formativa em educação artística. Por escrita dialógica, pretende-se frisar as potencialidades da construção de um texto que seja poliédrica, não hierarquizada, mas suficientemente fragmentada e entrecruzada para poder ser o reflexo de cada uma das autoras. Assume-se a narrativa como forma de pesquisa enquanto se escreve, uma escrita em devir e em diálogo pela qual se vai transformando a compreensão dos processos em análise e recriando os próprios processos de análise. Para além de uma reflexão teórica sobre a escrita e sobre as narrativas como processos de formação e investigação e de uma breve contextualização e apresentação metodológica, o artigo organiza as narrativas por temas, numa sucessão dialógica de textos de autoria individual, onde se mesclam discursos em prosa e poesia, comentados dialeticamente em textos conjuntos e posteriormente interpretadas do ponto de vista da formação e da investigação.

O presente estudo abordou a temática da inclusão de pessoas surdas, pretendeu-se, entre outros, identificar quais as dificuldades que os surdos encontram para se inserirem no mundo do trabalho. Realizou-se uma pesquisa bibliográfica sobre esse assunto, e na sequência, uma pesquisa exploratória em seis empresas de um município do Centro-Oeste do estado de Goiás, Brasil, na tentativa de localizar os surdos que estavam empregados, o que não se concretizou. Durante a visita a essas organizações aplicamos um questionário com os responsáveis pelo departamento de Recursos Humanos (RH) e se constatou a presença de vagas ociosas a esse público, na região, o que constata que essas pessoas não estejam empregadas. Posteriormente, foram localizados três surdos em uma empresa da região circunvizinha a esta cidade e aplicou-se uma entrevista com eles, com auxílio de uma intérprete da Língua Brasileira de Sinais (LIBRAS). A análise dos dados se deu de maneira discursiva, tendo uma abordagem qualitativa, sendo possível evidenciar que existem barreiras antes e após a inclusão do surdo no mercado de trabalho, pois esses indivíduos não recebem o auxílio e orientação necessária para a sua inserção e permanência nessa empresa.

Em 2015 ocorreu estado de emergência sanitária nacional devido a um surto em Pernambuco de neonatos com microcefalia. O objetivo desse estudo foi analisar as ações acerca do processo de inclusão de crianças com microcefalia no ensino regular. Foram selecionados estudos disponíveis nas bases de dados da SciELO e Google Acadêmico, no idioma português. Localizados 203 estudos, desses 196 não responderam à questão norteadora o que resultou na seleção de sete estudos. Observou-se nos estudos que a inclusão escolar desses alunos perpassa por diversos problemas: inadequação do ambiente físico, falta de recursos pedagógicos, materiais escolares necessários e profissionais especializados.  Ainda constatou-se a necessidade dos municípios e estados definirem políticas educacionais que possam garantir desde a matrícula em creche e pré-escolas à oferta de Atendimento Educacional Especializado. E, por fim, observou-se que os estudos sobre a inclusão escolar dos alunos com microcefalia ainda se encontram com pouca representatividade, sendo necessário um maior fomento em pesquisas que deem visibilidade a esse público, mas, também, é imprescindível investimento na formação dos recursos humanos para contribuírem na construção de melhores resultados frente ao processo de inclusão.
The Right Angle: Validating a standardised protocol for the use of infra-red thermography of eye temperature as a welfare indicator

Infra-red thermography (IRT) is a non-invasive tool for measuring eye temperature as an indicator of stress and welfare in animals. Previous studies state that images are taken from 90° but do not specify a reference point or method of standardisation. The aims of the current study were to determine whether the position of the IRT camera has an impact on recorded temperature and which camera position is optimal for indicating stress in a mammal with anterolateral eyes. IRT images were taken from 90° to the nasal plane, eye and sagittal plane on the left side of the horses’ faces (n = 14) at eye level before and after exposure to a novel object. Distance and angle of measurement was standardised using ground markers. Temperature at each point of measurement was compared against heart rate variability. A significant difference was found between recorded temperature at all three of the points of measurement, both before and after the novel object test, suggesting that IRT camera position has an impact on eye temperature results. There was a significant strong positive correlation between eye temperature taken from 90° to the sagittal plane and heart rate variability, but no such correlation was observed from 90° to the nasal plane or eye. This suggests that a 90° angle in relation to the sagittal plane is the optimal position for taking eye temperature measurements using IRT, whereas 90° to the eye is commonly used. This study offers a validated protocol for using IRT to measure stress and welfare in mammals with anterolateral eyes.
Trough half empty: Pregnant sows are fed under half of their ad libitum intake

Pregnant (dry) sows (Sus scrofa) are fed a rationed amount of feed to maintain healthy weight and production but this does not satisfy their hunger. This study measured the extent of feed restriction compared to sows’ desired intake. Forty-seven Large White × Landrace sows were housed in small groups with straw bedding and individual feeding stalls. Following three days on a standard ration of 2.5 kg, they were offered 10 kg a day of commercial dry sow feed for three days, split into four 2.5-kg meals a day which enabled individual intakes to be measured. This quantity was effectively ad libitum (maximum daily intake 9.4 kg). Mean (± SEM) intake per day over the three ad libitum days was 5.67 (± 0.24) kg, compared to the 2.5-kg standard ration. The ration thus provides less than half (44.1%) of sows’ desired intake. Behaviour on their third rationed day was compared with behaviour on the third day of ad libitum. Eating rate and the display of hunger-related behaviours, particularly following the morning feed, was greater under ration feeding; sows spent more time in the food stall and less in the straw bed, and more time active rather than resting. During ration-feeding sows also chewed and nosed more at straw bedding and pen equipment and used the drinker more after their morning meal than when they were fed ad libitum. Eating rate on the last rationed day was positively correlated with feed intake on each of the ad libitum days. Despite an EU requirement for fibre to be added to diets to ameliorate this problem, and the provision of straw bedding, hunger resulting from food restriction remains a welfare concern for dry sows.

This study aimed to identify current weak points in animal welfare in Danish dairy production at herd level using the Welfare Quality® (WQ) protocol, and at national level using the Danish Animal Welfare Index (DAWIN) protocol. The DAWIN was developed as a monitoring tool for the welfare of the Danish dairy cow population, derived from the aggregation of DAWIN assessments at herd level. The DAWIN dairy cow protocol covers 29 measures (13 resource- and 16 animal-based measures) that were weighted and aggregated into a final overall population welfare score. A total of 3,591 cows from 60 dairy herds were assessed throughout 2015. Results from both the WQ and DAWIN were presented at six criteria levels in order to identify specific areas of concern relating to animal welfare at herd versus population level. Both protocols indicated a good general level of welfare across study herds, but also identified insufficient water supply as the main area of concern. In addition, resting comfort (ie time needed to lie down, collisions with barn equipment, cleanliness of rear body parts, animals lying outside of the designated lying area) and disease (in terms of the proportion of cows with chronically elevated somatic cell counts) were identified as problematic areas. The two assessment protocols both identified behavioural deficits, but in the WQ it was due to zero-grazing systems in contrast to the insufficient numbers of cow brushes in the DAWIN protocol. Despite differences in the aggregation, similar areas of concern were identified at criteria level.
Do rabbits need each other? Effects of single versus paired housing on rabbit body temperature and behaviour in a UK shelter
Authors: Burn CC , Shields P
Published: April 2020

In the wild, rabbits (Oryctolagus cuniculus) are social but territorial. Recent surveys suggest that over half of pet rabbits are housed singly. We aimed to compare welfare in single versus paired rabbits. We predicted singletons would show more abnormal or escape behaviour, greater stress responses to handling, and reduced body temperature (being unable to huddle with another individual when cold), but that pairs may show aggression. This study was conducted during winter at a rabbit-only rescue centre, and included 45 rabbits, comprising 15 housed singly and 15 pairs. Like most pet rabbits, they were housed either outdoors or in unheated outbuildings. Singletons were mostly in smaller enclosures than pairs. Home-pen observations (40 min) revealed bar-biting in 8/15 single rabbits compared with 0/30 of the paired ones. No other behavioural effects of social housing reached significance, and enclosure size showed no significant effects. Body temperature was significantly lower in singletons than pairs, with at least 0.5°C mean difference. On colder days, rabbits adopted compact postures more, and relaxed postures less frequently. After handling, pairs resumed normal behaviour significantly more quickly than singletons in the home-pen (3.0 [± 0.3] versus 8.3 [± 1.3] s, respectively). Aggression was never observed. The results indicate that social housing reduces bar-biting, aids thermoregulation, and may help buffer stress. Rabbit owners should be encouraged to meet the need for rabbits to be housed with an appropriate conspecific in a suitably large, sheltered enclosure.
