Die lewe en werk van Karl Barth (1886–1968): ŉ Leksikografiese bydrae tot Reformasie 500
Authors: Van Wyk Gabriël M.J.
Published: August 2017

Karl Barth was a leading thinker within an influential theological direction that arose in Europeafter the First World War, known as dialectical theology. Comprehensive introductions to thelife and work of Barth in the South African theological journals, written in Afrikaans, eitherdoes not exist, or are difficult to trace for the Afrikaans readership. This article on Barth aims tofill the gap by offering a lexicographical contribution on the life and work of Barth. The focus ofthis article is on Barth as a Reformed theologian. The theme of the New Testament and systematictheology is essentially the same, namely to explain the concept of Christian self-understandingas an eschatological event in which faith is expressed for the sake of faith in God and only inGod. Barth explained the same theological concepts with his theology as those that wereexplained by the church reformers of the 16th century, but under radically new circumstances.The so-called modern and postmodern people of our time not only broke ties with the past, butin the process they also lost their ability for using historical-critical patterns of thought that triesto bridge historical distances, and therefore, sacrificed all efforts to think systematically on thealtar of relativism. We can learn from Barth what systematic reformed theology really is.

Mission as breaking down walls, opening gates and empowering traders: From contextualisation to deep contextualisation
Authors: Niemandt Cornelius J.P.
Published: August 2017

The research addressed the issue of symbolic walls that divide, segregate, preserve and institutionalise. The way in which institutions and especially the Faculty of Theology at the University of Pretoria facilitated symbolic ‘walls’ was discussed in the overview of the Department of Science of Religion and Missiology in the first century of the Faculty of Theology. The concepts of ‘gatekeepers’ and ‘traders’ were then applied because walls, paradoxically, need gates to facilitate control, movement and, eventually, life. Gatekeepers were described as the guardians of the status quo, and traders as agents who, in one way or another, facilitate movement, trade, flow and life in the midst of the shadows of walls. Missionaries are, by the very nature of the missionary enterprise, more traders than gatekeepers. Here, the work of Bosch – specifically his ground-breaking work on mission as contextualisation – provides an explanation of the art of mission as breaking down walls, opening gates and empowering traders. That is precisely why Missiology is particularly well suited to assist the church and theology in the art of breaking down walls. The theological imperative of contextualisation means that the life of the church, theology, and  thus theological training, cannot do without Missiology. The concept of ‘deep contextualisation’ was discussed as a particularly relevant approach to include a post-anthropomorphic discourse in Missiology. It can assist with the reorientation of the history of mission on the whole of history and, thus, also deep history. The concept also provides a way to address the discourses on colonialisation and includes a reorientation on the future and embracing hope.
(Confessional) Lutheran perspectives on the unity of the church
Authors: Reinstorf Dieter H.
Published: August 2017

From personal experience, this article shares to what degree the Faculty of Theology at the University of Pretoria was and continues to be a gateway to the future, challenging among others the divisions that characterise the Church of Christ worldwide. The article argues that for the 16th-century Reformers the unity of the church was a given and that the  (Lutheran) confessions were written to establish such a unity through agreement in confession and joint rejection of false doctrines. However, such statements of faith did not overcome the divisions, but institutionalised them, leading to a divided Church of Christ. Political intervention to work unity between Lutherans and Reformers deepened divisions more than ever, leading among others to a break of fellowship at the Lord’s Supper. Applying Luther’s hermeneutical principle of was Christum treibet (what drives Christ), the author seeks to rediscover a way of interpreting Scripture by focusing not on literal differences, but on that which is foundational to Scripture, namely the Christ event. This is applied in particular to the topic of table fellowship and divisions in Corinth with regard to the Lord’s Supper, addressed in 1 Corinthians 11, culminating in a critical deconstruction of past practices in confessional Lutheran churches. In view of doctrinal differences, a hermeneutics of conversation is proposed that can vigorously debate differences of understanding, without threatening the unity that is worked by Christ himself.
Seroprevalence and risk factors for Coxiella burnetii, the causative agent of Q fever in the dromedary camel (Camelus dromedarius) population in Algeria

Published: August 2017

Query (Q) fever is a globally distributed zoonotic disease caused by Coxiella burnetii, a bacterial agent for which ruminants are the most prevalent natural reservoir. Data regarding Q fever infection in camels in Algeria are limited. Therefore, a survey to detect seroprevalence of C. burnetii antibodies was conducted among healthy camel populations in a vast area in southeastern Algeria to determine distribution of the Q fever causative organism and to identify risk factors associated with infection. Between January and March 2016, blood samples were collected from 184 camels and serum samples were subsequently analysed using a commercial Enzyme-Linked Immunosorbent Assay (ELISA) kit. At the time of blood collection, a questionnaire investigating 13 potential predisposing factors associated with C. burnetii seropositivity was completed for every dromedary camel and herd. Results were analysed by a chi-square (χ2) test and multivariate logistic regression. The seroprevalence of C. burnetii at the animal level was 71.2% (95% CI: 65.2–78.3) and 85.3% (95% CI: 72.8–97.8) at the herd level. At the animal level, differences in seroprevalence were observed because of herd size, animal age, animal sex, presence of ticks and contact with other herds. A multivariable logistic regression model identified three main risk factors associated with individual seropositivity: (1) age class > 11 years (OR = 8.81, 95% CI: 2.55–30.41), (2) herd size > 50 head (OR = 4.46, 95% CI: 1.01–19.59) and (3) infestation with ticks (OR 2.2; 95% CI: 1.1–4.5). This study of seroprevalence of C. burnetii infection in camels in Algeria revealed a high seroprevalence of Q fever in camel populations in southeastern Algeria and provided strong evidence that Q fever represents an economic, public health and veterinary concern. Appropriate measures should be taken to prevent the spread of C. burnetii and to reduce the risk of Q fever in farm animals and humans in this agro-ecologically and strategically important region of North Africa.
Insomnia and risk of nonalcoholic fatty liver disease
Authors: Wijarnpreecha K , Thongprayoon C , Panjawatanan P , Ungprasert P
Published: August 2017

Aim:

This sudy aims to investigate the association between insomnia or excessive daytime sleepiness (EDS) and risk of nonalcoholic fatty liver disease (NAFLD).

Methods:

We searched published studies indexed in MEDLINE and EMBASE database from inception to December 2015. Studies that reported odds ratios (ORs), risk ratios, hazard ratios or standardized incidence ratio with 95% confidence intervals (CI) comparing the risk of NAFLD among participants who had insomnia or EDS versus those without insomnia or EDS were included. Pooled ORs and 95% CI were calculated using a random-effect, generic inverse variance method of DerSimonian and Laird. Cochran's Q test and I
2 statistic were used to determine the between-study heterogeneity.

Results:

Our search strategy yielded 2117 potentially relevant articles (781 articles from MEDLINE and 1336 articles from EMBASE). After comprehensive review, seven studies (three cross-sectional studies and four case–control studies) were found to be eligible and were included in the meta-analysis. The risk of NAFLD in participants who had insomnia was significantly higher with the pooled OR of 1.13 (95% CI, 1.00–1.27). The statistical heterogeneity was moderate with an I
2 of 62%. Elevated risk of NAFLD was also observed among participants with EDS even though the 95% CI was wider and did not reach statistical significance (pooled OR 2.21; 95% CI, 0.84–5.82). The statistical heterogeneity was moderate with an I
2 of 62%.

Conclusions:

Our study demonstrated an increased risk of NAFLD among participants who had insomnia or EDS. Whether this association is causal needs further investigations.
Acute myocardial infarction in yellow oleander poisoning
Authors: Anandhi D , Prakash Raju KNJ , Basha MH , Pandit VR
Published: August 2017

Self-harm by consuming yellow oleander seeds has become more frequent in South Asian countries, especially Sri Lanka and in southern parts of India. Yellow oleander poisoning usually presents with gastrointestinal, cardiovascular, and neurological manifestations as well as electrolyte abnormalities. Cardiac effects can manifest as nearly any type of dysrhythmia and sudden death with very few premonitory signs. To our knowledge yellow oleander poisoning related acute myocardial infarction has not yet been reported. We report a 37-year-old man with yellow oleander poisoning who had normal sinus rhythm at presentation but within few hours developed acute ST-segment myocardial infarction.
Association of anti-CLIC2 and anti-HMGB1 autoantibodies with higher disease activity in systemic lupus erythematosus patients
Authors: Syahidatulamali CS , Wan Syamimee WG , Azwany Y Nor , Wong KK , Che Maraina CH
Published: August 2017

Background:

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by numerous autoantibodies. In this study, we investigated the presence of anti-chloride intracellular channel 2 (anti-CLIC2) and anti-high mobility group box 1 (anti-HMGB1) autoantibodies in SLE patients (n = 43) versus healthy controls ([HCs] n = 43), and their association with serological parameters (antinuclear antibody [ANA], anti-double-stranded DNA [anti-dsDNA], and C-reactive protein [CRP]) and disease activity using Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score (active or inactive).

Settings and Design:

Case–control study at Rheumatology Clinic of Universiti Sains Malaysia Hospital.

Subjects and Methods:

The sera of SLE patients and HCs were tested for the presence of anti-CLIC2 and anti-HMGB1 autoantibodies using human recombinant proteins and ELISA methodologies. Other serological parameters were evaluated according to routine procedures, and patients’ demographic and clinical data were obtained.

Statistical Analysis:

Mann–Whitney U-test, Chi-square test, Fisher's exact test, and receiver operating characteristic analysis.

Results:

Anti-CLIC2 autoantibody levels were significantly higher in SLE patients compared to HCs (P = 0.0035), whereas anti-HMGB1 autoantibody levels were not significantly elevated (P = 0.7702). Anti-CLIC2 and anti-HMGB1 autoantibody levels were not associated with ANA pattern, anti-dsDNA, and CRP. Interestingly, SLEDAI score (≥6) was associated with anti-CLIC2 (P = 0.0046) and with anti-HMGB1 (P = 0.0091) autoantibody levels.

Conclusion:

Our findings support the potential of using anti-CLIC2 autoantibodies as a novel biomarker for SLE patients. Both anti-CLIC2 and anti-HMGB1 autoantibody levels demonstrated potential in monitoring SLE disease activity.
Isolated left-sided pulmonary artery agenesis with left lung hypoplasia
Authors: Govindaraj V , Joseph J , Kumar B Nagamalli , Soman R
Published: August 2017

Unilateral absence of pulmonary artery or pulmonary artery agenesis (UAPA) is a rare congenital malformation that can present as an isolated lesion or in association with other cardiac anomalies. Though congenital, presentation in adults are also reported. Most common presentation in adults is of exercise intolerance. The developing lung on the affected side is hypoplastic. Diagnosis of UAPA is established by imaging methods like CT and MRI. There is no specific treatment for this condition. Treatment depends on patients symptomatology, presence of pulmonary hypertension and collateral circulation. Presence of pulmonary hypertension carries a bad prognosis. We present two adult patients with isolated left sided unilateral pulmonary artery agenesis with ipsilateral lung hypoplasia. The diagnosis was confirmed by CT chest and perfusion scan.
Hypereosinophilia
Authors: Narayanan G , Soman LV , Kumar R
Published: August 2017

Acute lymphoblastic leukaemia (ALL) presenting as peripheral blood hypereosinophilia is very rare and the incidence is <1%. The characteristic feature of patients with ALL and hypereosinophilia is the absence of blasts in peripheral blood, and this might lead to misdiagnosis of ALL. It is important for clinicians and pathologists to be aware of this uncommon initial presentation of ALL to avoid delay in diagnosis. We report a 37-year-old man who presented with fever and respiratory symptoms and was found to have hypereosinophilia in peripheral blood. His bone marrow and lymph node biopsies were diagnostic of ALL.

MEP (Maps for Easy Paths) is a project for the enrichment of geographical maps with information about accessibility of urban pedestrian pathways, targeted at people with mobility problems. In this paper, we describe the tools developed to collect data along the paths travelled by target people and the algorithms for a good quality reconstruction of the path developed to overcome the intrinsic limitation of the sensors available on mobile devices. Experimental results show the feasibility of the approach.
All-sky photogrammetry techniques to georeference a cloud field
Authors: Crispel Pierre , Roberts Gregory
Published: August 2017

Abstract. In this study, we present a novel method of identifying and geolocalizing cloud field elements from a portable all-sky camera stereo network based on the ground and oriented towards zenith. The methodology is mainly based on stereophotogrammetry which is a 3D reconstruction technique based on triangulation from corresponding stereo pixels in rectified images. In cases where clouds are horizontally separated, identifying individual positions is performed with segmentation techniques based on hue filtering and contour detection algorithms. Macroscopic cloud field characteristics such as cloud layer base heights and velocity fields are also deduced. In addition, the methodology is fitted to the context of measurement campaigns which impose simplicity of implementation, auto-calibration, and portability. Camera internal geometry models are achieved a priori in the laboratory and validated to ensure a certain accuracy in the peripheral parts of the all-sky image. Then, stereophotogrammetry with dense 3D reconstruction is applied with cameras spaced 150 m apart for two validation cases. The first validation case is carried out with cumulus clouds having a cloud base height at 1500 m a.g.l. The second validation case is carried out with two cloud layers: a cumulus fractus layer with a base height at 1000 m a.g.l. and an altocumulus stratiformis layer with a base height of 2300 m a.g.l. Velocity fields at cloud base are computed by tracking image rectangular patterns through successive shots. The height uncertainty is estimated by comparison with a Vaïsala CL31 ceilometer located on the site. The uncertainty on the horizontal coordinates and on the velocity field are theoretically quantified by using the experimental uncertainties of the cloud base height and camera orientation. In the first cumulus case, segmentation of the image is performed to identify individuals clouds in the cloud field and determine the horizontal positions of the cloud centers.
Effects of the planetary waves on the MLT airglow
Authors: Egito Fabio , Takahashi Hisao , Miyoshi Yasunobu
Published: August 2017

Abstract. The planetary-wave-induced airglow variability in the mesosphere and lower thermosphere (MLT) is investigated using simulations with the general circulation model (GCM) of Kyushu University. The model capabilities enable us to simulate the MLT OI557.7 nm, O2b(0–1), and OH(6–2) emissions. The simulations were performed for the lower-boundary meteorological conditions of 2005. The spectral analysis reveals that at middle latitudes, oscillations of the emission rates with the period of 2–20 days appear throughout the year. The 2-day oscillations are prominent in the summer and the 5-, 10-, and 16-day oscillations dominate from the autumn to spring equinoxes. The maximal amplitude of the variations induced by the planetary waves was 34 % in OI557.7 nm, 17 % in O2b(0–1), and 8 % in OH(6–2). The results were compared to those observed in the middle latitudes. The GCM simulations also enabled us to investigate vertical transport processes and their effects on the emission layers. The vertical transport of atomic oxygen exhibits similar periodic variations to those observed in the emission layers induced by the planetary waves. The results also show that the vertical advection of atomic oxygen due to the wave motion is an important factor in the signatures of the planetary waves in the emission rates.
Post-depositional vivianite formation alters sediment phosphorus records
Authors: Dijkstra Nikki , Hagens Mathilde , Egger Matthias , Slomp Caroline P.
Published: August 2017

Abstract. Phosphorus (P) concentrations in sediments are frequently used to reconstruct past environmental conditions in freshwater and marine systems, with high values thought to be indicative of a high biological productivity. Recent studies suggest that the post-depositional formation of vivianite, an iron(II)-phosphate mineral, might significantly alter trends in P with sediment depth. To assess its importance, we investigate a sediment record from the Bornholm Basin that was retrieved during the IODP Baltic Sea Paleoenvironment Expedition 347 in 2013, consisting of lake sediments overlain by brackish-marine deposits. Combining bulk sediment geochemistry with micro-analysis using scanning electron microscope energy dispersive spectroscopy (SEM-EDS) and synchrotron-based X-ray absorption spectroscopy (XAS), we demonstrate that manganese- and magnesium-rich vivianite is present in the lake deposits just below the transition to the brackish-marine sediments (at 11.5 to 12 m sediment depth). In this depth interval, phosphate that diffuses down from the organic-rich, brackish-marine sediments meets porewaters rich in dissolved iron in the lake sediments, resulting in vivianite precipitation. Results from a reactive transport model suggest that the peak in vivianite originally occurred at the lake-marine transition (9 to 10 m) and moved downwards due to changes in the depth of a sulfidization front. However, its current position relative to the lake-marine transition is stable as the vivianite and active sulfidization fronts have been spatially separated over time. Experiments in which vivianite was subjected to sulfidic conditions demonstrate that incorporation of manganese or magnesium in vivianite does not affect its susceptibility to sulfide-induced dissolution. Our work highlights that post-depositional vivianite formation has the potential to strongly alter sedimentary P records particularly in systems that are subject to environmental perturbation, such as a change in primary productivity, which can be associated with a lake-marine transition.
Global Inventory of Gas Geochemistry Data from Fossil Fuel, Microbial and Burning Sources, version 2017
Authors: Sherwood Owen A. , Schwietzke Stefan , Arling Victoria A. , Etiope Giuseppe
Published: August 2017

Abstract. The concentration of atmospheric methane (CH4) has more than doubled over the industrial era. To help constrain global and regional CH4 budgets, inverse (top-down) models incorporate data on the concentration and stable carbon (δ13C) and hydrogen (δ2H) isotopic ratios of atmospheric CH4. These models depend on accurate δ13C and δ2H end-member source signatures for each of the main emissions categories. Compared with meticulous measurement and calibration of isotopic CH4 in the atmosphere, there has been relatively less effort to characterize globally representative isotopic source signatures, particularly for fossil fuel sources. Most global CH4 budget models have so far relied on outdated source signature values derived from globally nonrepresentative data. To correct this deficiency, we present a comprehensive, globally representative end-member database of the δ13C and δ2H of CH4 from fossil fuel (conventional natural gas, shale gas, and coal), modern microbial (wetlands, rice paddies, ruminants, termites, and landfills and/or waste) and biomass burning sources. Gas molecular compositional data for fossil fuel categories are also included with the database. The database comprises 10 706 samples (8734 fossil fuel, 1972 non-fossil) from 190 published references. Mean (unweighted) δ13C signatures for fossil fuel CH4 are significantly lighter than values commonly used in CH4 budget models, thus highlighting potential underestimation of fossil fuel CH4 emissions in previous CH4 budget models. This living database will be updated every 2–3 years to provide the atmospheric modeling community with the most complete CH4 source signature data possible.

END-TO-END DEPTH FROM MOTION WITH STABILIZED MONOCULAR VIDEOS
Authors: Pinard C. , Chevalley L. , Manzanera A. , Filliat D.
Published: August 2017

Abstract. We propose a depth map inference system from monocular videos based on a novel dataset for navigation that mimics aerial footage from gimbal stabilized monocular camera in rigid scenes. Unlike most navigation datasets, the lack of rotation implies an easier structure from motion problem which can be leveraged for different kinds of tasks such as depth inference and obstacle avoidance. We also propose an architecture for end-to-end depth inference with a fully convolutional network. Results show that although tied to camera inner parameters, the problem is locally solvable and leads to good quality depth prediction.
PERFORMANCE ASSESSMENT OF INTEGRATED SENSOR ORIENTATION WITH A LOW-COST GNSS RECEIVER
Authors: Rehak M. , Skaloud J.
Published: August 2017

Abstract. Mapping with Micro Aerial Vehicles (MAVs whose weight does not exceed 5 kg) is gaining importance in applications such as corridor mapping, road and pipeline inspections, or mapping of large areas with homogeneous surface structure, e.g. forest or agricultural fields. In these challenging scenarios, integrated sensor orientation (ISO) improves effectiveness and accuracy. Furthermore, in block geometry configurations, this mode of operation allows mapping without ground control points (GCPs). Accurate camera positions are traditionally determined by carrier-phase GNSS (Global Navigation Satellite System) positioning. However, such mode of positioning has strong requirements on receiver’s and antenna’s performance. In this article, we present a mapping project in which we employ a single-frequency, low-cost (
ON THE QUALITY AND EFFICIENCY OF APPROXIMATE SOLUTIONS TO BUNDLE ADJUSTMENT WITH EPIPOLAR AND TRIFOCAL CONSTRAINTS
Authors: Schneider J. , Stachniss C. , Förstner W.
Published: August 2017

Abstract. Bundle adjustment is a central part of most visual SLAM and Structure from Motion systems and thus a relevant component of UAVs equipped with cameras. This paper makes two contributions to bundle adjustment. First, we present a novel approach which exploits trifocal constraints, i.e., constraints resulting from corresponding points observed in three camera images, which allows to estimate the camera pose parameters without 3D point estimation. Second, we analyze the quality loss compared to the optimal bundle adjustment solution when applying different types of approximations to the constrained optimization problem to increase efficiency. We implemented and thoroughly evaluated our approach using a UAV performing mapping tasks in outdoor environments. Our results indicate that the complexity of the constraint bundle adjustment can be decreased without loosing too much accuracy.
PRECISE POSITIONING OF UAVS – DEALING WITH CHALLENGING RTK-GPS MEASUREMENT CONDITIONS DURING AUTOMATED UAV FLIGHTS
Authors: Zimmermann F. , Eling C. , Klingbeil L. , Kuhlmann H.
Published: August 2017

Abstract. For some years now, UAVs (unmanned aerial vehicles) are commonly used for different mobile mapping applications, such as in the fields of surveying, mining or archeology. To improve the efficiency of these applications an automation of the flight as well as the processing of the collected data is currently aimed at. One precondition for an automated mapping with UAVs is that the georeferencing is performed directly with cm-accuracies or better. Usually, a cm-accurate direct positioning of UAVs is based on an onboard multi-sensor system, which consists of an RTK-capable (real-time kinematic) GPS (global positioning system) receiver and additional sensors (e.g. inertial sensors). In this case, the absolute positioning accuracy essentially depends on the local GPS measurement conditions. Especially during mobile mapping applications in urban areas, these conditions can be very challenging, due to a satellite shadowing, non-line-of sight receptions, signal diffraction or multipath effects. In this paper, two straightforward and easy to implement strategies will be described and analyzed, which improve the direct positioning accuracies for UAV-based mapping and surveying applications under challenging GPS measurement conditions. Based on a 3D model of the surrounding buildings and vegetation in the area of interest, a GPS geometry map is determined, which can be integrated in the flight planning process, to avoid GPS challenging environments as far as possible. If these challenging environments cannot be avoided, the GPS positioning solution is improved by using obstruction adaptive elevation masks, to mitigate systematic GPS errors in the RTK-GPS positioning. Simulations and results of field tests demonstrate the profit of both strategies.
ASSESSING CHANGES IN POTATO CANOPY CAUSED BY LATE BLIGHT IN ORGANIC PRODUCTION SYSTEMS THROUGH UAV-BASED PUSHBROOM IMAGING SPECTROMETER

Published: August 2017

Abstract. Productivity of cropping systems can be constrained simultaneously by different limiting factors and approaches allowing to indicate and identify plants under stress in field conditions can be valuable for farmers and breeders. In organic production systems, sensing solutions are not frequently studied, despite their potential for crop traits retrieval and stress assessment. In this study, spectral data in the optical domain acquired using a pushbroom spectrometer on board of a unmanned aerial vehicle is used to evaluate the potential of this information for assessment of late blight (Phytophthora infestans) incidence on potato (Solanum tuberosum) under organic cultivation. Vegetation indices formulations with two and three spectral bands were tested for the complete range of the spectral information acquired (i.e., from 450 to 900 nm, with 10 nm of spectral resolution). This evaluation concerned the discrimination between plots cultivated with only one resistant potato variety in contrast with plots with a variety mixture, with resistant and susceptible cultivars. Results indicated that indices based on three spectral bands performed better and optimal wavelengths (i.e., near 490, 530 and 670 nm) are not only related to chlorophyll content but also to other leaf pigments like carotenoids.
POTENTIAL OF MULTI-TEMPORAL UAV-BORNE LIDAR IN ASSESSING EFFECTIVENESS OF SILVICULTURAL TREATMENTS
Authors: Vepakomma U. , Cormier D.
Published: August 2017

Abstract. Silvicultural treatments are practiced to control resource competition and direct forest stand development to meet management objectives. Effective tracking of thinning and partial cutting treatments help in timely mitigation and ensuring future stand productivity. Based on a study conducted in autumn 2015, our findings in a white pine dominant forest stand in Petawawa (Ontario, Canada) showed that almost all individual trees were detectable, structure of individual trees and undergrowth was well pronounced and underlying terrain below dense undisturbed canopy was well captured with UAS based Riegl Vux-1 lidar even at a range of 150 m. Thereafter, the site was re-scanned the following summer with the same system. Besides understanding the difference in distribution patterns due to foliage conditions, co-registering the two datasets, in the current study, we tested the potential of quantifying effectiveness of a partial cutting silvicultural system especially in terms of filling of 3D spaces through vertical or lateral growth and mortality in a very short period of time.
DISTRIBUTED UAV-SWARM-BASED REAL-TIME GEOMATIC DATA COLLECTION UNDER DYNAMICALLY CHANGING RESOLUTION REQUIREMENTS
Authors: Almeida M. , Hildmann H. , Solmaz G.
Published: August 2017

Abstract. Unmanned Aerial Vehicles (UAVs) have been used for reconnaissance and surveillance missions as far back as the Vietnam War, but with the recent rapid increase in autonomy, precision and performance capabilities – and due to the massive reduction in cost and size – UAVs have become pervasive products, available and affordable for the general public. The use cases for UAVs are in the areas of disaster recovery, environmental mapping & protection and increasingly also as extended eyes and ears of civil security forces such as fire-fighters and emergency response units. In this paper we present a swarm algorithm that enables a fleet of autonomous UAVs to collectively perform sensing tasks related to environmental and rescue operations and to dynamically adapt to e.g. changing resolution requirements. We discuss the hardware used to build our own drones and the settings under which we validate the proposed approach.
Review Article: Validation of flood risk models: current practice and
innovations
Authors: Molinari Daniela , De Bruijn Karin , Castillo Jessica , Aronica Giuseppe T. , Bouwer Laurens M.
Published: August 2017

Abstract. Although often neglected, model validation is a key topic in flood risk analysis, as flood risk estimates are characterised by significant levels of uncertainty. In this paper, we discuss the state of art of flood risk models validation, as concluded from the discussion among more than 50 experts at two main scientific events. The events aimed at identifying policy and research recommendations towards promoting more common practice of validation, and an improvement of flood risk models reliability. We pay specific attention to the different components of the risk modelling chain (i.e. flood hazard, defence failure and flood damage analysis) as well as to their role into risk estimates, to highlight specificities and commonalities with respect to implemented techniques and research needs. The main conclusions from this review can be summarised as the need of higher quality data to perform validation and of benchmark solutions to be followed in different contexts, along with a greater involvement of end-users in the debate on flood risk models validation.

Analisamos sob a ótica da interculturalidade, a política de formação continuada dos professores indígenas, entendida aqui como uma educação diferenciada direcionada a esses professores, como parte de um projeto estatal de formação para a autonomia e a cidadania. A perspectiva pós-colonial permite-nos reforçar a importância de análises que conjuguem os aspectos da dominação e da resistência. Abordamos a perspectiva crítica da interculturalidade na educação indígena que considera as identidades culturais de cada povo como possibilidade de deslocamento epistêmico em sua formação. O trabalho tem como fio condutor o conceito da interculturalidade, e destaca autores que dão sustentação teórica a este caminho investigativo: Walsh (2009), Fleuri (2003), Mato (2009), Bhabha (2003) entre outros. Adotou-se como procedimento técnico-metodológico para este caminho investigativo  a revisão bibliográfica, assim como a possibilidade de privilegiar  entrevistas com professores indígenas, trazendo algumas inquietações desses sujeitos formados pelo programa de educação intercultural e a Ação ‘Saberes Indígenas na Escola’. Este estudo procura demonstrar o aspecto complexo e ambivalente da construção de uma educação intercultural em MS, indicando como as relações de poder, saber, ser são indicativos da produtividade no campo educacional. Apontamos a interculturalidade como possibilidade de relações menos assimétricas na educação, como uma possibilidade de descolonização epistêmica em busca de uma forma de ser, viver e saber outra, o que indica uma flexibilização epistêmica, possibilitando estratégias políticas pedagógicas outras. Assim propomos uma formação intercultural em todos espaços tempos como possibilidade de se respeitar as diferenças e alteridade. Palavras-chave: Interculturalidade. Educação indígena.

A TRANSMISSÃO DE NOMES GAVIÃO: FABRICANDO PESSOAS E COLETIVIDADES (GAVIÃO PYHCOPCATI JI – AMAZÔNIA MARANHENSE)
Authors: Melo Maycon , Gavião Paulo Belizário
Published: August 2017

RESUMOOs Gavião Pyhcopcati ji são um povo falante do tronco linguístico MacroJê, que vive na parte sudoeste do Estado do Maranhão, na Amazônia maranhense. Quando uma criança nasce, um conjunto de nomes pessoais lhe é transmitido, criando relações sociais com diferentes pessoas e grupos que irão perpassar toda sua vida e morte. O nome também vincula o indivíduo à esfera cerimonial, lhe atribuindo funções e posições específicas nas performances realizadas no pátio. Atualmente, muitos nomes são substituídos nas conversas cotidianas pelos nomes em português, o que parece ter colocado uma questão de ordem sócio-cosmológica e não apenas linguística aos Gavião. O artigo discute a transmissão de nomes entre os Gavião e a forma como está relacionada à construção de pessoas e de coletivos a partir de momentos ritualizados e fundamentais para a continuidade da vida.Palavras Chave: Gavião Pyhcopcatiji.

Ética e técnica em Jonas e Levinas: diferenciações e aproximações
Authors: Carrara Ozanan Vicente
Published: August 2017

O presente artigo aborda, a partir de alguns textos e passagens dos filósofos Jonas e Levinas, sobretudo Technologie et Responsabilité, do primeiro, e Heidegger, Gagarine et nous, do segundo, a questão da relação entre ética e técnica. Jonas funda a ética em uma ontologia, sendo a técnica, em sua concepção, parte constitutiva da natureza humana, aquilo mesmo que instala o homem na humanidade, ligando-a o autor à preservação e à continuidade da existência em todos os níveis: o da existência humana e o da existência não humana. Para Levinas, a ética dispensa uma ontologia que a prepare, sendo ela mesma a filosofia primeira. Sendo sua ética um esforço de buscar o humano em toda sua profundidade, concebe a técnica como aquilo que permite perceber o humano em toda sua intensidade, libertando-o do mundo e do contexto, abrindo a possibilidade de uma subjetividade que é habitação, acolhimento e aceitação de outrem. Após caracterizar o pensamento da ética em ambos os autores e de situar a técnica e a tecnologia dentro de seus projetos éticos, o artigo busca os elementos comuns nos dois pensadores que ajudam a pensar a ética ambiental e suas questões fundamentais, como as da humanidade e animalidade, encontrando um elemento comum na noção de responsabilidade tão fundamental às formas de os dois autores pensarem a ética. É pela responsabilidade que éticas tão diferentes conservam uma abertura à alteridade, seja na forma das futuras gerações (Jonas), seja ao outro, na figura do Rosto (Levinas), que, alargada, pode incluir também os seres não humanos.
Motivações socioeconômicas para a conservação e exploração sustentável do bioma Caatinga

Published: August 2017

Nesse trabalho propõe-se contribuir com as discussões sobre a exploração sustentável da Caatinga através de uma atualização bibliográfica sobre o tema, destacando a importância desse bioma, suas potencialidades e a necessidade de sua preservação e conservação. Foram abordadas a importância socioeconômica do bioma, as estratégias de subsistência e geração de renda (como o extrativismo e bioprodutos de valor econômico), as políticas públicas e ameaças, além de avaliar o seu uso sustentável. Com base no exposto, compreende-se que o manejo sustentável é uma possibilidade real, tecnicamente comprovada. Faz-se necessário um intenso processo de conscientização e capacitação de todos os atores envolvidos por meio da formulação de políticas públicas, que priorizem a realidade ambiental e socioeconômica do bioma, da geração, sistematização e disseminação de informações, da construção de uma matriz de incentivos adaptados à realidade local e do fortalecimento institucional, como forma de garantir a sobrevivência do ecossistema.
ÍNDICE DE POSIÇÃO TOPOGRÁFICA (IPT) PARA CLASSIFICAÇÃO GEOMORFOMÉTRICA DAS FORMAS DE RELEVO NO ESTADO DO PARANÁ - BRASIL
Authors: Silveira Claudinei Taborda , Silveira Ricardo Michael Pinheiro
Published: August 2017

A geomorfometria tem favorecido o tratamento quantitativo nos estudos e representação das formas do relevo, sobretudo a partir de parâmetros calculados de Modelos Digitais do Terreno (MDTs). Nessa perspectiva, o trabalho teve como objetivo realizar a classificação geomorfométrica automatizada das formas de relevo do Paraná, Brasil, por meio da aplicação do Índice de Posição Topográfica (IPT), seguido da avaliação de sua distribuição nas subunidades morfoesculturais do Mapa Geomorfológico do Paraná e análise da fidedignidade classificatória do método apoiado no reconhecimento de campo em cinco áreas amostrais distribuídas no território paranaense. O MDT com resolução de 20m, foi interpolado pelo método Topogrid da base planialtimétrica nas escalas 1:50.000 e 1:25.000. Conforme proposta aplicada, o IPT foi derivado da mensuração entre a diferença da elevação de um ponto central com a média da elevação do seu entorno a partir de um raio predeterminado. As dez formas de relevo resultantes são decorrentes da discretização amparada pelos valores de desvio padrão e da combinação de dois IPTs (um de detalhe, com janela circular de leitura com raio de 8 células, e outro generalizado com raio de 79 células). Os resultados demonstraram, numa perspectiva regional, que o emprego do IPT permitiu identificar arranjos distintos com padrões de formas de relevo predominantes que foram coincidentes com os limites pré-estabelecidos das subunidades morfoesculturais do estado. Na perspectiva local, as dez formas de relevo mapeadas foram condizentes com a realidade de campo em quatro recortes, sendo que um deles demonstrou limitação na representação do planalto de baixa declividade da região noroeste com as planícies, o que retrata a dificuldade da plena representação do relevo considerando os mesmos parâmetros indistintamente em todo o Paraná.
ANÁLISE GEOMORFOLÓGICA APLICADA AOS ESTUDOS DE VIAS DE TRANSPORTE TERRESTRE
Authors: Sampaio Tony Vinicius Moreira , Sopchaki Carlos Henrique
Published: August 2017

Estudos envolvendo geomorfologia são utilizados em diversas áreas, possibilitando o entendimento dos processos ambientais que modelam a superfície da Terra e afetam a segurança e o desenvolvimento humano. A análise geomorfológica é fundamental para o planejamento territorial e ambiental, devendo subsidiar a realização de projetos e obras em qualquer escala espacial de análise. Neste sentido, a análise geomorfológica integra os estudos relativos à caracterização do meio físico no que concerne à vias de transporte terrestre, como rodovias e ferrovias. Destaca-se que a análise geomorfológica é parte obrigatória dos estudos sobre vias de transporte terrestre em território brasileiro, sendo a responsável pela caracterização dos processos, materiais e formas que afetam a segurança destas. Sendo assim, o objetivo deste artigo é propor uma reflexão acerca do potencial da análise geomorfológica aplicada ao planejamento, implantação e recuperação de vias de transporte terrestre de variadas dimensões (centenas de metros a centenas de quilômetros), abordando temas como fontes de dados, inventário de campo, diversidade metodológica, condicionantes para escolha da abordagem metodológica, limitações impostas pela escala, utilização de modelos digitais de representação do relevo e adequação das áreas de influência direta e indireta.
A Reflection on Parents’ Responsibility for Harmful Acts of Major, Foolish and Physically Disabled Children in the Islamic Jurisprudence and Iranian Law
Authors: Heidari Siroos , Khodaie Amir Ali , Janbazi Davood
Published: August 2017

In this research, we seek to talk about civil responsibility of parents for acts of their children with juridical and legal approach. The main problem is that whether the parents have civil responsibility for harmful acts of their major and foolish children or not. The parents have civil responsibility for harmful acts of their foolish children (minor or mature) until they have custody on them. In the opinion of most of Islamic jurists, the parents’ right and duty of custody on their children will be expired by majority and mental maturity of the child. In addition, the parents will be liable for damages derived from the acts of their minor or insane children until they have protection and supervision duty on them. In all of the cases, failure to take care of the incapable person constitutes the legal basis of the parents’ liability. It may be said that the parents have responsibility for any losses arising from their failure to protect and take care of their physical disable children.
