Revolution ohne Kiel und ohne Revolution – Die quantitativ-theoretische Geographie in Erlangen
Authors: Paulus Katharina
Published: October 2017

Abstract. This article aims at expanding the predominant narrative of a Quantitative Revolution in German-speaking geography, to develop a more complex and multifaceted perspective on this chapter of the discipline's history. For this purpose, I take a closer look at the institute of geography in Erlangen. Eugen Wirth, the long-term chair holder in Erlangen, argued that here, in contrast to the majority of other institutes, the implementation of quantitative methods started in 1932, when Walter Christaller submitted his thesis: Central Places in Southern Germany. According to Wirth a dissertation supervised by him in 1969 was a further step towards the use of quantitative methods. I argue that Wirth made a significant contribution to the debate on quantitative theoretical geography in Germany with his textbook Theoretical Geography published in 1979, although the book was subsequently criticised and strongly rejected by Bartels and others as a conservative embrace. By examining this local negotiation process, I develop one of many narratives, that stand opposed to a unified account with which the general assembly of geographers in 1969 and Bartels' Geographie des Menschen uniquely motivated the abandonment of the concept of Länderkunde.
DEM GENERATION FROM CLOSE-RANGE PHOTOGRAMMETRY USING EXTENDED PYTHON PHOTOGRAMMETRY TOOLBOX
Authors: Belmonte A. A. , Biong M. M. P. , Macatulad E. G.
Published: October 2017

Abstract. Digital elevation models (DEMs) are widely used raster data for different applications concerning terrain, such as for flood modelling, viewshed analysis, mining, land development, engineering design projects, to name a few. DEMs can be obtained through various methods, including topographic survey, LiDAR or photogrammetry, and internet sources. Terrestrial close-range photogrammetry is one of the alternative methods to produce DEMs through the processing of images using photogrammetry software. There are already powerful photogrammetry software that are commercially-available and can produce high-accuracy DEMs. However, this entails corresponding cost. Although, some of these software have free or demo trials, these trials have limits in their usable features and usage time. One alternative is the use of free and open-source software (FOSS), such as the Python Photogrammetry Toolbox (PPT), which provides an interface for performing photogrammetric processes implemented through python script. For relatively small areas such as in mining or construction excavation, a relatively inexpensive, fast and accurate method would be advantageous. In this study, PPT was used to generate 3D point cloud data from images of an open pit excavation. The PPT was extended to add an algorithm converting the generated point cloud data into a usable DEM.

Published: October 2017

Abstract. This paper presents the development of TM model by using the radiosonde stations from Peninsular Malaysia. Two types of TM model were developed; site-specific and regional models. The result revealed that the estimation from site-specific model has small improvement compared to the regional model, indicating that the regional model is adequately to use in estimation of GPS-derived IWV over Peninsular Malaysia. Meanwhile, this study found that the diurnal cycle of TS has influenced the TM–TS relationship. The separation between daytime and nighttime observation can improve the relationship of TM–TS. However, the impact of diurnal cycle to IWV estimation is less than 1 %. The TM model from Global and Tropic also been evaluated. The Tropic TM model is superior to be utilized as compared to the Global TM model.

Published: October 2017

Abstract. Over the years, the acquisition technique of bathymetric data has evolved from a shipborne platform to airborne and presently, utilising space-borne acquisition. The extensive development of remote sensing technology has brought in the new revolution to the hydrographic surveying. Satellite-Derived Bathymetry (SDB), a space-borne acquisition technique which derives bathymetric data from high-resolution multispectral satellite imagery for various purposes recently considered as a new promising technology in the hydrographic surveying industry. Inspiring by this latest developments, a comprehensive study was initiated by National Hydrographic Centre (NHC) and Universiti Teknologi Malaysia (UTM) to analyse SDB as a means for shallow water area acquisition. By adopting additional adjustment in calibration stage, a marginal improvement discovered on the outcomes from both Stumpf and Lyzenga algorithms where the RMSE values for the derived (predicted) depths were 1.432 meters and 1.728 meters respectively. This paper would deliberate in detail the findings from the study especially on the accuracy level and practicality of SDB over the tropical environmental setting in Malaysia.
EFFECT OF LONG TERM TIDAL CONSTITUENTS ON MEAN SEA LEVEL TREND DURING EL-NINO AND LA-NINA PHENOMENA
Authors: Yusof N. H. M. , Mahmud M. R. , Abdullah M. H.
Published: October 2017

Abstract. There are many factors that influence the change of the tidal constituent pattern. The factors can be classified as astronomical factors and non- astronomical factors. The astronomical factors involve the gravitational force attraction by the moon and sun. The distance of sun and moon influence the gravitational attractions that are produced by the moon and sun towards earth surface. Non-astronomical factors involved the movements of currents, waves, temperature and so on which is cause by the phenomenon such as El-Nino, La-Nina. This study was conducted to investigate the effect of these phenomena towards the pattern of tidal constituent during the phenomenon on several stations that have been chosen. The difference stations were chose due to the change in the position of celestial body. In addition, tidal data for several stations were processed using the UTM Tidal Analysis and Prediction Software (μ-TAPS). Based on the tidal data that has been processed, the graphs were plotted for the predicted data and observed data to compare the different pattern between the data. The tidal data that has been processed were used to analyse the pattern of tidal constituents based on the changing amplitude of M2, S2, K1, O1, Sa, Ssa, Mm, Mf and MSf.
PERCEPTION MODELLING OF VISITORS IN VARGAS MUSEUM USING AGENT-BASED SIMULATION AND VISIBILITY ANALYSIS
Authors: Carcellar III B. G.
Published: October 2017

Abstract. Museum exhibit management is one of the usual undertakings of museum facilitators. Art works must be strategically placed to achieve maximum viewing from the visitors. The positioning of the artworks also highly influences the quality of experience of the visitors. One solution in such problems is to utilize GIS and Agent-Based Modelling (ABM). In ABM, persistent interacting objects are modelled as agents. These agents are given attributes and behaviors that describe their properties as well as their motion. In this study, ABM approach that incorporates GIS is utilized to perform analyticcal assessment on the placement of the artworks in the Vargas Museum. GIS serves as the backbone for the spatial aspect of the simulation such as the placement of the artwork exhibits, as well as possible obstructions to perception such as the columns, walls, and panel boards. Visibility Analysis is also done to the model in GIS to assess the overall visibility of the artworks. The ABM is done using the initial GIS outputs and GAMA, an open source ABM software. Visitors are modelled as agents, moving inside the museum following a specific decision tree. The simulation is done in three use cases: the 10 %, 20 %, and 30 % chance of having a visitor in the next minute. For the case of the said museum, the 10 % chance is determined to be the closest simulation case to the actual and the recommended minimum time to achieve a maximum artwork perception is 1 hour and 40 minutes. Initial assessment of the results shows that even after 3 hours of simulation, small parts of the exhibit show lack of viewers, due to its distance from the entrance. A more detailed decision tree for the visitor agents can be incorporated to have a more realistic simulation.
VARIATION OF CHART DATUM TOWARDS MARITIME DELIMITATION DUE TO RISING SEA LEVEL
Authors: Faizuddin A. R. M. , Razali M. M.
Published: October 2017

Abstract. The importance of Chart Datum in hydrographic surveying is inarguable because its determination is part of the process to obtain the actual depth of bathymetry. The Chart Datum has a relationship with the determination of base points because any uncertainty of the base points would definitely cause uncertainty to the determination of the maritime baseline. If there is any doubt on the baselines, it will then cause doubt on the maritime zones as well which includes the equidistant line that forms the border between the two countries. However, due to the ongoing rising sea level, there has been some variations of the Chart Datum in some areas in Malaysia. This research discusses about the variation of Mean Sea Level and Chart Datum for the tide gauge stations at Geting, Cendering, Sedili and Tioman at East Coast and Kukup, Langkawi, Lumut and Penang at the West Coast of Peninsular Malaysia. The tidal analysis was carried out by using the 23 years of data beginning at 1993 to 2015. The observed tidal data for 23 years were processed and analysed by using GeoTide software. In this research, the Harmonic Analysis technique was used in order to calculate the values of Mean Sea Level and the Chart Datum while the slope of the shoreline is modelled by using Global Mapper. The linear trend of the Mean Sea Level and the Chart Datum was analysed to determine the increase of the annual sea level in millimetres accuracy and also to determine the variation of the Chart Datum for each tidal station and its impact towards maritime baseline. The result has shown that the linear trend of sea level rise varies from 24 millimetres per year up to 168 millimetres per year at the East Coast and 24 millimetres per year up to 96 millimetres per year at the West Coast of Peninsular Malaysia. As for the maritime baseline, results has indicated that there exist shifting in the horizontal which are varies from 1.564 metres per year to 3.299 metres per year at the East Coast and from 1.331 metres per year up to 5.857 metres per year at the West Cost of Peninsular Malaysia. From the analysis, it can be stated that the horizontal shift occur greater at the East Coast rather than at the West Coast of Peninsular Malaysia. As a conclusion, the sea level rise does have significant impact towards maritime baseline. Furthermore, the determination of a stable Chart Datum is important to define the maritime baseline in other to avoid conflict with other neighbouring countries.
ARSENIC-SAFE AQUIFERS IN COASTAL BANGLADESH: AN INVESTIGATION WITH ORDINARY KRIGING ESTIMATION
Authors: Hassan M. M. , Ahamed R.
Published: October 2017

Abstract. Spatial point pattern is one of the most suitable methods for analysing groundwater arsenic concentrations. Groundwater arsenic poisoning in Bangladesh has been one of the biggest environmental health disasters in recent times. About 85 million people are exposed to arsenic more than 50 μg/L in drinking water. The paper seeks to identify the existing suitable aquifers for arsenic-safe drinking water along with “spatial arsenic discontinuity” using GIS-based spatial geostatistical analysis in a small study site (12.69 km2) in the coastal belt of southwest Bangladesh (Dhopakhali union of Bagerhat district). The relevant spatial data were collected with Geographical Positioning Systems (GPS), arsenic data with field testing kits, tubewell attributes with observation and questionnaire survey. Geostatistics with kriging methods can design water quality monitoring in different aquifers with hydrochemical evaluation by spatial mapping. The paper presents the interpolation of the regional estimates of arsenic data for spatial discontinuity mapping with Ordinary Kriging (OK) method that overcomes the areal bias problem for administrative boundary. This paper also demonstrates the suitability of isopleth maps that is easier to read than choropleth maps. The OK method investigated that around 80 percent of the study site are contaminated following the Bangladesh Drinking Water Standards (BDWS) of 50 μg/L. The study identified a very few scattered “pockets” of arsenic-safe zone at the shallow aquifer.
Development and assessment of uni- and multi-variable flood loss models for Emilia-Romagna (Italy)
Authors: Carisi Francesca , Schröter Kai , Domeneghetti Alessio , Kreibich Heidi , Castellarin Attilio
Published: October 2017

Abstract. Simplified flood loss models are one important source of uncertainty in flood risk assessments. Many countries experience sparseness or absence of comprehensive high-quality flood loss data sets which is often rooted in a lack of protocols and reference procedures for compiling loss data sets after flood events. Such data are an important reference for developing and validating flood loss models. We consider the Secchia river flood event of January 2014, when a sudden levee-breach caused the inundation of nearly 52 km2 in Northern Italy. For this event we compiled a comprehensive flood loss data set of affected private households including buildings footprint, economic value, damages to contents, etc. based on information collected by local authorities after the event. By analysing this data set we tackle the problem of flood damage estimation in Emilia-Romagna (Italy) by identifying empirical uni- and multi-variable loss models for residential buildings and contents. The accuracy of the proposed models is compared with those of several flood-damage models reported in the literature, providing additional insights on the transferability of the models between different contexts. Our results show that (1) even simple uni-variable damage models based on local data are significantly more accurate than literature models derived for different contexts; (2) multi-variable models that consider several explanatory variables outperform uni-variable models which use only water depth. However, multi-variable models can only be effectively developed and applied if sufficient and detailed information is available.

Abstract. The orientations and densities of fractures in the foliated hanging-wall of the Alpine Fault provide insights into the role of a mechanical anisotropy in upper crustal deformation, and the extent to which existing models of fault zone structure can be applied to active plate-boundary faults. Three datasets were used to quantify fracture damage at different distances from the Alpine Fault principal slip zones (PSZs): (1) X-ray computed tomography (CT) images of drill-core collected within 25 m of the PSZs during the first phase of the Deep Fault Drilling Project that were reoriented with respect to borehole televiewer images, (2) field measurements from creek sections at

Published: October 2017

Abstract. Sea ice thickness evolution within the Canadian Arctic Archipelago (CAA) is of great interest. In this study, based on the NEMO numerical frame work including the LIM2 sea ice module, simulations at both 1/4° and 1/12° horizontal resolution were conducted from 2002 to 2016. The model captures well the general spatial distribution of ice thickness in the CAA region, with very thick sea ice (∼&rthinsp;4 m and thicker) in the northern CAA, thick sea ice (2.5 m to 3 m) in the west-central Parry Channel and M'Clintock Channel, and thin (
Fluctuating dental asymmetry in rabbits with familial nonsyndromic coronal suture synostosis
Authors: Hyre Mae A. , Weinberg Seth M. , Cooper Gregory M. , Gilbert James , Siegel Michael I. , Mooney Mark P.
Published: October 2017

Fluctuating dental asymmetry has been linked to conditions of unstable pre- and peri-natal development. Familial, nonsyndromic craniosynostosis disrupts early craniofacial development through localized excessive calvarial ossification leading to the premature fusion of the calvarial sutures. Such abnormal gene expression may also produce systemic stress resulting in developmental instability, thereby affecting normal trait symmetry. The present study was designed to test this hypothesis by examining fluctuating dental asymmetry in an inbred strain of rabbits with familial, nonsyndromic coronal craniosynostosis.  The mesiodistal (MD) and buccolingual (BL) dimensions of the right and left maxillary first molars were measured in four groups of New Zealand white rabbits (N=176; n=40 with early-onset synostosis, n=65 with delayed-onset synostosis, n=46 in-colony, phenotypically normal rabbits, and n=25 wild-type normal controls). For each variable, raw signed asymmetry was calculated (left-right) and tested for assumptions of fluctuating asymmetry (i.e., normality and non-directionality). Any group that did not meet these assumptions was excluded from further analysis. Using a standard size-adjusted, fluctuating asymmetry index, mean fluctuating asymmetry was calculated and compared across groups with non-parametric statistics.  For the MD dimension, no significant (p > 0.05) group differences in mean fluctuating asymmetry were observed among groups. In contrast, rabbits with early-onset synostosis had significantly (p < 0.05) more fluctuating asymmetry in the BL dimension compared to wild-type controls.  Results demonstrate increased fluctuating dental asymmetry in rabbits with nonsyndromic, early-onset coronal suture synostosis and suggest that the molecular events producing suture synostosis locally may have also have systemic effects. Knowledge of these systemic interactions may contribute to a fuller understanding of the phenotypic spectrum observed in individuals with nonsyndromic craniosynostosis.
RECALQUES EM FUNDAÇÕES PROFUNDAS – ANÁLISE EM ESTACAS HÉLICE CONTÍNUA
Authors: Prununciati Pedro Lucas , Garcia Jean Rodrigo , Rodriguez Tiago Garcia
Published: October 2017

RESUMO:  O recalque em fundações profundas e sua influência numa edificação tem se mostrado um parâmetro crítico, já que em diversos projetos a capacidade de carga não é o fator limitante, mas sim o recalque que a estrutura pode suportar em seu estado limite de serviço (ELS). Neste trabalho, são analisados resultados de deslocamento para uma estaca, estimados a partir dos métodos de Poulos e Davis (1980), Vésic (1969, 1975a) e Cintra e Aoki (2010), comparando-os com o valor recalque obtido por ensaios de prova de carga. Para tal, se apresentam três ensaios com carregamento do tipo lento, seguindo instruções da NBR12131 (ABNT, 2006), executados em estacas hélice contínua instrumentadas, com comprimentos de 14,75 m, 12,85 m e 21,80 m e diâmetros de 70 cm, 60 cm e 70 cm, respectivamente. Essas estacas foram ensaiadas no munícipio de Itatiba, em uma região onde sondagens à percussão demonstram a predominância de areia e silte. Para as estacas analisadas, o método proposto por Cintra e Aoki (2010) mostrou melhor resultado para a estimativa do recalque, quando comparado aos resultados de recalque obtidos em prova de carga. O método Poulos e Davis (1980) obteve desempenho menos satisfatório, resultando uma margem de erro de 16%, para mais ou para menos. O método de Vésic (1969, 1975a) se mostrou conservador e, nos casos analisados, resultou uma superestimativa de 138%, quando comparados aos valores de prova de carga.ABSTRACT: The settlement in deep foundations and its influence appears to be a critical parameter, as in many projects, the load capacity of a pile is not the limiting factor, but the settlement which the structure can suffer on its serviceability limit state (SLS) is. In this research, the settlement results of a pile, estimated by the methods of Poulos e Davis (1980), Vésic (1969, 1975a) and Cintra e Aoki (2010) will be analyzed, to be compared with the value of settlement obtained from load tests. Three slow type load tests, following the instructions of NBR12131 (ABNT, 2006) are presented, carried out in instrumented continuous flight augers, with lengths of 14,75 m, 12,85 m and 21,80 m and diameters of 70 cm, 60 cm and 70 cm, respectively. Those piles were tested in the city of Itatiba, in a region where standard penetration tests evidenced the predominance of sand and silt. In the analyzed piles, the Cintra e Aoki (2010) method has shown the best result for a settlement estimate, when compared with the value obtained by a load test. The Poulos e Davis method (1980) obtained a less satisfactory performance, resulting a margin of sampling error of plus or minus 16%. The Vésic method (1969, 1975a) has shown to be conservative, resulting, in the analyzed cases, an overestimate of 138%, when compared with the load tests values.

Published: October 2017

The relevant literature suggests that ownership structure is one of the main corporate governance mechanisms influencing the scope of financial performance. The aim of this study is to investigate the relationship between ownership structure and financial performance of listed beverage food and tobacco companies for the period of 2010-2015. This study also examines the impact of ownership structure on financial performance. The sample consists of 10 listed beverage food and tobacco companies in Sri Lanka. In this study, data was collected from secondary sources and hypotheses are examined by using Pearson’s correlation and regression analysis. The results reveal that ownership concentration and foreign ownership structure are positively correlated with financial performance of listed beverage food and tobacco companies while institutional ownership structure isn’t significantly correlated with financial performance. It is also found that there is a significant impact of foreign ownership structure on financial performance. Higher the foreign ownership structure in listed beverage food and tobacco companies, the higher the financial performance which is preferable for the shareholders and it improves the wealth of companies.
Does Sustainability Increase Financial Performance? A Quantitative Comparison between the S&P 500 and S&P 500 ESG Factor Weighted Index
Authors: Stein Smith Sean
Published: October 2017

As the business environment continues to be influenced by stakeholder forces, including sustainability reporting and sustainable operations, a question that continues to be asked is if such a mindset delivers financial returns. While there is increased interest and attention on the areas of sustainability reporting and financial returns, quantitatively addressing this question is a complicated task. Leveraging the proliferation of ETFs, this analysis compares the performance of the S&P 500 ESG Factor Weighted Index versus the S&P 500 during the period 2014-2016. As business decisions are driven in large part by the financial performance of the organizations, this research is applicable to both practitioner and academic members of the accounting community. Additionally, the second aspect of this research attempts to establish a connection between sustainability, integrated reporting, and begin the analysis whether or not there appears to be a connection between performance and integrated reporting.
Value Relevance of DuPont Identity
Authors: Gupta Pradeep Kumar
Published: October 2017

This study provides an empirical support to the relevance of very prevalent and well-established almost a century ago the DuPont Identity in the context of India, one of big 10 emerging markets (Garten, 1997). The DuPont Identity, a familiar form of financial statement analysis (Soliman, 2008) for use in equity valuation (Nissim and Penman, 2001), decomposes the return on equity (ROE) into three multiplicative components: net profit margin (operating efficiency), assets turnover ratio (asset use efficiency) and equity multiplier (financial leverage). The present study is based on the valuation theory which considers the viewpoint of equity investors to empirical investigate the value relevance of accounting information (Beisland, 2009). In this study, value relevance of three measures of accounting information used in the DuPont Identity is investigated for 228 manufacturing firms listed in National Stock Exchange (NSE) of India over a period of ten years from 2006-07 to 2015-2016. The findings indicate that the firms should focus on asset use efficiency and financial leverage components of DuPont Identity since a statistically significant impact of these two components on the stock returns is found. The strategic use of asset efficiency and financial leverage inevitably ensures the operating efficiency of the firms. This empirical investigation is an addition to the value relevance literature with an important insight to the firms and the participants of stock market about the usefulness of DuPont Identity in the context of India.
Assessing Teaching Format as it Applies to Motivation and Perceptions of Teaching and Learning in Geological Sciences Education
Authors: Merchant William , Dees David
Published: October 2017

Objective: This study sought to compare the motivation and classroom level perceptions of students participating in three different classroom formats (i.e. lecture only, data/lecture, lab/data/lecture). Method: A Multivariate Analysis of Variance (MANOVA) was used to compare subscales from the Motivation Strategies and Learning Questionnaire (MSLQ) and Experiences of Teaching and Learning Questionnaire (ETLQ) across the three teaching formats. A correlational analysis was then conducted examining relationships within and between MSLQ and ETLQ subscales and select student outcomes. Results: Teaching format was not found to be a significant factor in relation to student motivation or class level perceptions except for the perception of choice which was higher for the lecture only format. A strong collection of correlations suggest that classroom and teacher level variables are positively related to deep learning. Conclusion: This study found that class format is not as impactful on student level outcomes as is their perception of the learning environment and teacher interactions.

Joe Keller's Motivation for Suicide inAll My Sons: A New Reading
Authors: Casper Vivian
Published: October 2017

Although various motivations have been analyzed for Joe Keller's suicide in All My Sons, this essay argues for a new motivation by reexamining Joe's psychology, dialogic consistency, symbolism in the play, suicides in other Miller plays, and Miller's Chekhovian technique. Joe's motivation for suicide is to preserve his manufacturing business and pass it to Chris. To live, once Joe's secret is exposed, would endanger his mission. In his final practical, psychological, and philosophical battle with Chris, Joe wins, that is, achieves his goal, in the only way he knows how. If all elements of the play and their cohesiveness are considered, All My Sons then does not have a flawed ending, puzzling previous interpreters, but is a well-crafted, coherent work of art.

As características químicas em conjunto com a estrutura de bosques de mangue são informações fundamentais para compreender a dinâmica deste ambiente. O objetivo foi analisar parâmetros químicos e a estrutura de bosque em manguezais com diferente pressão antrópica, um deles localizado próximo a um complexo industrial e ao porto de Paranaguá na vila Becker, e o segundo, situado em uma Unidade de Conservação na Floresta Estadual do Palmito. Foi avaliado o teor de fósforo, matéria orgânica, amônio, nitrato e nitrogênio disponível, assim como a densidade e diâmetro na altura do peito de Rizhophorae mangle, Laguncularia racemosa e Aviscenia schaueriana. O manguezal da Vila Becker apresentou maiores concentrações de fósforo, amônio e nitrogênio total. Não houve diferenças entre os manguezais com relação a estrutura de bosque, a Rizophorae mangle apresentou a maior densidade entre as espécies, independente do manguezal avaliado. A proximidade destes ambientes ao meio urbano e industrial pode pôr em risco suas características naturais e assim promover alterações na sua dinâmica.

A qualidade estrutural dos solos vem sendo avaliada por indicadores físicos obtidos em condições laboratoriais, que embora sejam os mais aceitos, têm obtenção onerosa, além do tempo necessário para transporte das amostras e demora na apresentação dos resultados. A análise visual da estrutura obtida em campo vem sendo apontada como opção viável para o diagnóstico da qualidade física do solo, constituindo uma importante ferramenta para identificar ou monitorar práticas de manejo sustentáveis. Assim, este trabalho teve por objetivo analisar a relação entre análise visual e laboratorial da estrutura objetivando diagnóstico da qualidade física de diferentes solos. Utilizou-se delineamento experimental inteiramente casualizado em esquema fatorial duplo, sendo os fatores as classes de solos (LVd, CXbd e NXd), avaliadas em diferentes profundidades (amontoa; 0,05-0,15 m; 0,25-0,35 m; e 0,45-0,55 m ), em triplicata. A avaliação se apoiou na aparência visual da estrutura dos solos após 5 anos da implantação de um sistema de manejo conservacionista, sendo avaliadas a resistência e outros atributos das unidades estruturais dos solos, categorizados por 5 Scores visuais (Ev) utilizados na classificação da qualidade da estrutura, variando de Ev =1 (melhor qualidade) a Ev =5 (pior qualidade). Nas profundidades de 0,25-0,35 m e 0,45-0,55 m, o LVd apresentou Score visual menor quando comparado ao NXd e CXbd, indicando sua melhor condição estrutural nestas profundidades. A análise de componentes principais  demonstrou que a quantificação dos atributos densidade do solo, microporosidade, teor de silte e poros da classe de diâmetro < 0,6 µm contribuíram para justificar o aumento do Ev.

O objetivo foi avaliar a influência dos tipos de uso e manejo do solo sobre a fauna edáfica em diferentes épocas do ano. O delineamento experimental foi de blocos ao acaso com parcelas subdivididas, em três repetições, sendo instaladas duas armadilhas por subparcela, totalizando 36 armadilhas. Os sistemas de preparo do solo foram o plantio direto com cobertura hibernal de aveia, o plantio direto com o uso de consórcio de aveia + ervilhaca + nabo e o preparo convencional do solo com cobertura de aveia. Nas subparcelas foram implantadas as culturas de abóbora e abobrinha de tronco como culturas comerciais. A abundância da fauna do solo foi analisada pelos índices de diversidade de Shannon, Simpson e Pielou. Adicionalmente os dados analisados como ordens foram submetidos à análise multivariada de Componentes Principais (ACP). A fauna edáfica sofre influência dos sistemas de manejo, mostrando-se bem mais diversa no sistema de plantio direto. As plantas de cobertura influenciam na diversidade e abundancia da fauna edáfica. Consequentemente, as diferentes épocas de coletas influenciam a fauna do solo, principalmente pela diferente oferta de alimento em cada época amostral. Os organismos mais frequentes foram os Collembola, independente dos tratamentos e época de coleta.

Atualmente, os penetrômetros mais utilizados classificam-se em função do seu princípio de penetração. Porém, independentemente do modo de operação, é importante que a determinação da resistência mecânica a penetração seja de forma precisa e, de preferência, que haja confiabilidade e proximidade de seus resultados. O presente trabalho objetivou comparar os valores da resistência do solo à penetração, por meio dos penetrômetros de impacto e eletrônico, e avaliar sua eficiência correlacionando-os com os atributos de qualidade física do solo. Os estudos foram realizados em Neossolo sob transição a um Cambissolo, em manejo convencional de integração lavoura pecuária em sucessão soja-aveia preta, no município de Jardim Alegre, Paraná. A avaliação da resistência mecânica a penetração ocorreu mediante ao penetrômetro de impacto IAAPLANALSUCAR/STOLF e penetrômetro eletrônico PLG 1020 penetroLOG2. Foi realizado um delineamento inteiramente casualizado, com quatro repetições em parcelas de 10.000 m², avaliando-se 30 pontos amostrais por repetição nas profundidades de 0-5 cm; 5-10 cm; 10-20 cm; 20-30 cm; 0-30 cm. Em conjunto, foram coletadas amostras deformadas e indeformadas para avaliação de densidade aparente e porosidade total, umidade gravimétrica e textura do solo. A partir dos resultados obtidos, constatou-se que os penetrômetros de impacto e eletrônico apresentam similaridade no comportamento, entretanto, o penetrômetro de impacto representa melhor as condições do solo.

Há uma carência de informações sobre formas de propagação sexuada da pitombeira (Talisia esculenta), quanto ao seu desenvolvimento inicial em ambientes salinos. Neste sentido, objetivou-se avaliar o efeito da irrigação com águas salinas associada à aplicação de biofertilizante bovino e cobertura vegetal morta em mudas de pitombeira. Adotou-se o delineamento experimental inteiramente casualizado, no esquema fatorial de 5 x 2 x 2, com 6 repetições. Foram estudadas cinco condutividades elétricas da água de irrigação (1;2;3;4 e 5 dS m-1) com e sem aplicação de biofertilizante bovino e cobertura morta. Avaliaram-se: altura da planta, número de folhas, diâmetro do caule, área foliar, taxa de crescimento absoluto e relativo de altura da planta, diâmetro de caule e área foliar, comprimento da raiz, massa da matéria seca da raiz, caule, parte aérea e total e índice de qualidade de Dickson. Os dados obtidos foram avaliados mediante análise de variância pelo teste F em nível de 0,05 e 0,01 de probabilidade e nos casos de significância, realizou-se análise de regressão. A irrigação com água salinas afeta a morfologia e a qualidade de mudas de pitombeira. O biofertilizante possui ação positiva na redução dos efeitos salinos da água de irrigação nas mudas de pitombeira, enquanto que o uso de cobertura morta não influenciou na qualidade de mudas de pitombeira.
Changing the ward culture in a clinic during the implementation of person-centred care

Objective: The purpose of this study was to explore the impact of an intervention on the organizational culture in five hospital wards in Sweden. The organizational culture was measured at the start of the project and compared with data collected five years later. The intervention was aimed at changing activities towards a new evidenced-based care model called the Gothenburg Person-centred Care model (PCC).Methods: In total, 230 registered nurses and assistant nurses participated in this cross-sectional health-care culture survey during 2009 and 2014. The Organizational Values Questionnaire was used.Results: The results indicated cultural change in all five wards at the clinic. A dominating culture of flexibility decreased and a culture of routines and structure increased. The wards moved towards a higher degree of cultural uniformity. The combination of cultural dimensions also seems to have become more equal during the study period.Conclusions: Few studies have focussed on the development of organizational culture in health-care contexts over time. The results suggest that the implementation of a new model of care has an impact on organizational culture. This implies that health-care managers should have confidence in the outcomes from change projects. It seems that systems of dual logic can develop over time to facilitate change and sustainability. However, if a new working model is to change the culture profoundly, it requires years of zealous implementation.
Sovereign Democratic Transformation in Ecuador (2007-2016)
Authors: Echavarria Ricardo Restrepo
Published: October 2017

Between 1981 and 2007, Ecuador experienced neoliberal reforms coupled with an elite form of democracy. These led to slow growth, upwards redistribution, and political and economic instability. Since then, Ecuador adopted a Citizens’ Revolution to counteract these economic and political forms of domination. This paper advances a few elements of the theoretical understanding of democratic justice inspired by the constitutional vision of Buen Vivir, and their policy applications in reconfiguring the political institutions that shape the state and its international relations. The application in the Citizens’ Revolution movement and historical phase has helped advance the democratization of the Constitution, the Executive, the Legislative, the Judicial system, political rights, the right to life, freedom of expression, national natural resources and investments, external public debt, as well as social rights and the welfare state.

The use of herbicides amongst smallholder farmers is minimal because herbicides are expensive and they require specialized application equipments. Weeds are problematic in conservation agriculture where herbicides are expensive for smallholder farmers. The use of cover crops can help to suppress weed growth and development by creating an environment which is not suitable for weeds survival. Cowpea (Vigna unguiculata (L.) Walp) dolichos lablab (Lablab purpureus L.) and velvet bean (Mucuna pruriens (L.) DC) were evaluated for biomass accumulation and weed suppression under conservation agriculture system in two contrasting experimental sites: Ukulinga and Bergville in KwaZulu-Natal. Bare plot and herbicide treatments served as controls. Treatments were laid in a randomized complete block design, replicated three times. Mucuna pruriens (L.) DC had the highest biomass accumulation in both sites Bergville (0.72 t/ha) and Ukulinga (1.59 t/ha). Cowpea had the lowest biomass accumulation in Bergville (0.59 t/ha) and lablab was the lowest in Ukulinga (0.88 t/ha). Lablab was effective in suppressing weed biomass in Bergville (P < 0.05). Cowpea performed best in suppressing weed biomass in Ukulinga (P < 0.05). The results suggest that cowpea and lablab can be effective for weed suppression and therefore can be recommended for use in conservation agricultural systems.

Published: October 2017

The main objective of the study is to assess the variation of agriculture in the Podkarpackie Voivodeship, both in terms of the production potential and the productivity of the factors of production. The purpose of the analysis is to measure the variation of the level of agriculture in the regions of the Podkarpackie Voivodship using a synthetic measure. The application of the synthetic measure will allow for the ordering of objects (counties of Podkarpackie Voivodeship, excluding four cities with district status) in terms of achieved level of agricultural development and indication of poorest and least developed districts from the point of view of the examined phenomenon. At the next stage, cluster analysis was carried out to isolate the typological groups. Based on cluster analysis, five internally homogeneous and externally distinct groups of poorest. Results of the research proved that the best production potential of agriculture is characterized by the following counties: mielecki, dębicki, ropczycko-sędziszowski, przeworski, lubaczowski, jarosławski, łańcucki and leżajski. On the other hand, the worst situation of agriculture, because of the analyzed characteristics, can be indicated in poviats: bieszczadzki, stalowowolski and leski.
