Bakgrund: Vilken roll har företag i vårt samhälle? Vilken funktion ska de fylla? Är företagens funktion att vara vinstmaximerande och enbart se till sitt eget bästa, eller har de ett större ansvar och skyldigheter mot samhället? Dessa frågor har diskuterats under lång tid och bilden av företag och företagande förändras kontinuerligt i takt med att samhället förändras. Tankarna om att företag har ett socialt ansvar, vid sidan av det ekonomiska, har spridit sig över världen och frågor som har dykt upp är om det finns någon motsättning mellan socialt ansvar och företagens vinstintresse. Eller kan det vara så att socialt ansvarstagande kan leda till ökad lönsamhet? Syfte: Att genom en empirisk undersökning ge en förklaring om svenska noterade bolags rapporterade arbete med CSR har en positiv inverkan på dess lönsamhet. Metod: För att uppnå syftet valdes en deduktiv kvantitativ metod för att kunna göra en statistisk generalisering. Det rapporterade CSR-arbetet operationaliseras med hjälp av Folksams rapport "Index för ansvarsfullt företagande" och lönsamhet mäts via avkastning på totalt kapital (ROA) samt vinstmarginal. Analysen genomförs med hjälp av multipla regressionsanalyser. Slutsats: Studiens resultat visar att företags rapporterade CSR-arbete har en positiv inverkan på svenska noterade företags lönsamhet, både mätt i avkastning på totalt kapital (ROA) och vinstmarginal.

On 28 July 2010, the Nigerian Federal Executive Council approved January 1, 2012 as the effective date for the convergence of Nigerian Statement of Accounting Standards (SAS) or Nigerian GAAP (NG-GAAP) with International Financial Reporting Standards (IFRS). By this pronouncement, all publicly listed companies and significant public interest entities in Nigeria were statutorily required to issue IFRS based financial statements for the year ended December, 2012. This study investigates the impact of the adoption of IFRS on the financial statements of Nigerian listed Oil and Gas entities using six years of data which covers three years before and three years after IFRS adoption in Nigeria and other African countries. First, the study evaluates the impact of IFRS adoption on the Exploration and Evaluation (E&E) expenditures of listed Oil and Gas companies. Second, it examines the impact of IFRS adoption on the provision for decommissioning of Oil and Gas installations and environmental rehabilitation expenditures. Third, the study analyses the impact of the adoption of IFRS on the average daily Crude Oil production cost per Barrel. Fourth, it examines the extent to which the adoption and implementation of IFRS affects the Key Performance Indicators (KPIs) of listed Oil and Gas companies. The study further explores the impact of IFRS adoption on the contractual relationships between Nigerian Government and Oil and Gas companies in terms of Joint Ventures (JVs) and Production Sharing Contracts (PSCs) as it relates to taxes, royalties, bonuses and Profit Oil Split. A Paired Samples t-test, Wilcoxon Signed Rank test and Gray’s (Gray, 1980) Index of Conservatism analyses were conducted simultaneously where the accounting numbers, financial ratios and industry specific performance measures of GAAP and IFRS were computed and analysed and the significance of the differences of the mean, median and Conservatism Index values were compared before and after IFRS adoption. Questionnaires were then administered to the key stakeholders in the adoption and implementation of IFRS and the responses collated and analysed. The results of the analyses reveal that most of the accounting numbers, financial ratios and industry specific performance measures examined changed significantly as a result of the transition from GAAP to IFRS. The E&E expenditures and the mean cost of Crude Oil production per barrel of Oil and Gas companies increased significantly. The GAAP values of inventories, GPM, ROA, Equity and TA were also significantly different from the IFRS values. However, the differences in the provision for decommissioning expenditures were not statistically significant. Gray’s (Gray, 1980) Conservatism Index shows that Oil and Gas companies were more conservative under GAAP when compared to the IFRS regime. The Questionnaire analyses reveal that IFRS based financial statements are of higher quality, easier to prepare and present to management and easier to compare among competitors across the Oil and Gas sector but slightly more difficult to audit compared to GAAP based financial statements. To my knowledge, this is the first empirical research to investigate the impact of IFRS adoption on the financial statements of listed Oil and Gas companies. The study will therefore make an enormous contribution to academic literature and body of knowledge and void the existing knowledge gap regarding the impact and implications of IFRS adoption on the financial statements of Oil and Gas companies.

La falta de claridad en relación a los modelos de desarrollo pertinentes para esta región amazónica, frente a los actuales escenarios de globalización, y la falta de voluntad política, han profundizado problemáticas estructurales (violencia, desempleo, pobreza, desigualdad, entre otros), reflejadas en sus bajos niveles de desarrollo; es así, como durante la historia, el departamento del Caquetá y por tanto sus municipios, se ha caracterizado por afrontar sus procesos de desarrollo en una forma espontánea y desordenada, con falencias en su planeación y mediada por iniciativa propia de los actores institucionales o impuesto por planes elaborados a nivel central o de instancias internacionales.

Esta monografía es el análisis financiero actual de la ebanistería JAR. Se propuso desde el principio conocer la situación real financiera de la ebanistería para dar una orientación a los dueños de la compañía, sobre que decisiones puedan tomar para mejorar los resultados de la empresa. Para llevar a cabo el análisis y el diagnóstico financiero de la ebanistería, se tomó como base los balances y estados financieros de los años 2011 hasta el 2014. Adicionalmente se recopilo información financiera de empresas del sector para compararlos con los resultados de la ebanistería JAR. En base a la información recopilada, se sacaron los indicadores de endeudamiento, liquidez, rentabilidad e inductores de valor. Toda esta información es analizó y cotejó para obtener las conclusiones y recomendaciones esperadas. La ebanistería JAR no se encuentra en una difícil situación financiera como los dueños de la ebanistería lo habían planteado en un comienzo. Más bien sus directivos están comparando épocas muy distintas de la historia de la ebanistería y de la historia económica de Colombia que los hace pensar que las cosas no están bien. Cuando se hace el análisis comparativo de los indicadores de rentabilidad de la ebanistería JAR contra las ebanisterías del sector, se encuentra que los indicadores de rentabilidad ROA y RONA, son incluso levemente superiores a los del sector para el año 2014.

In order to optimize frontal detection in sea surface temperature fields at 4 km resolution, a combined statistical and expert-based approach is applied to test different spatial smoothing of the data prior to the detection process. Fronts are usually detected at 1 km resolution using the histogram-based, single image edge detection (SIED) algorithm developed by Cayula and Cornillon in 1992, with a standard preliminary smoothing using a median filter and a 3 × 3 pixel kernel. Here, detections are performed in three study regions (off Morocco, the Mozambique Channel, and north-western Australia) and across the Indian Ocean basin using the combination of multiple windows (CMW) method developed by Nieto, Demarcq and McClatchie in 2012 which improves on the original Cayula and Cornillon algorithm. Detections at 4 km and 1 km of resolution are compared. Fronts are divided in two intensity classes (“weak” and “strong”) according to their thermal gradient. A preliminary smoothing is applied prior to the detection using different convolutions: three type of filters (median, average and Gaussian) combined with four kernel sizes (3 × 3, 5 × 5, 7 × 7, and 9 × 9 pixels) and three detection window sizes (16 × 16, 24 × 24 and 32 × 32 pixels) to test the effect of these smoothing combinations on reducing the background noise of the data and therefore on improving the frontal detection. The performance of the combinations on 4 km data are evaluated using two criteria: detection efficiency and front length. We find that the optimal combination of preliminary smoothing parameters in enhancing detection efficiency and preserving front length includes a median filter, a 16 × 16 pixel window size, and a 5 × 5 pixel kernel for strong fronts and a 7 × 7 pixel kernel for weak fronts. Results show an improvement in detection performance (from largest to smallest window size) of 71% for strong fronts and 120% for weak fronts. Despite the small window used (16 × 16 pixels), the length of the fronts has been preserved relative to that found with 1 km data. This optimal preliminary smoothing and the CMW detection algorithm on 4 km sea surface temperature data are then used to describe the spatial distribution of the monthly frequencies of occurrence for both strong and weak fronts across the Indian Ocean basin. In general strong fronts are observed in coastal areas whereas weak fronts, with some seasonal exceptions, are mainly located in the open ocean. This study shows that adequate noise reduction done by a preliminary smoothing of the data considerably improves the frontal detection efficiency as well as the global quality of the results. Consequently, the use of 4 km data enables frontal detections similar to 1 km data (using a standard median 3 × 3 convolution) in terms of detectability, length and location. This method, using 4 km data is easily applicable to large regions or at the global scale with far less constraints of data manipulation and processing time relative to 1 km data.

El objetivo del estudio es describir las prácticas sociales que el Estado, las escuelas y familias elaboran para abordar la inclusión de la discapacidad sensorial visual y auditiva en el contexto educativo de la ciudad de Copiapó. Participaron expertos en temáticas de inclusión sensorial, profesores y familias de niños y jóvenes con alguna discapacidad sensorial. Se realizó desde un enfoque cualitativo de tipo descriptivo, incorporando algunas de las fases analíticas propuestas por el método de la Teoría Fundamentada, utilizando entrevistas, observaciones participantes y análisis de documentos. Se concluyó que los informantes claves consideran la inclusión educativa deficiente en lo que respecta a los recursos materiales, acceso físico al establecimiento, recursos técnicos, humanos e infraestructura de los dispositivos educacionales. De esta manera existiría una distancia entre lo que declara el Estado chileno (leyes y decretos) y sus planes y programas, así como también entre lo que realiza la unidad educativa del establecimiento y lo que entienden las familias por inclusión al sistema educativo

Melanoma is a type of skin cancer and is caused by the uncontrolled growth of atypical melanocytes. In recent decades, computer aided diagnosis is used to support medical professionals; however, there is still no globally accepted tool. In this context, similar to state-of-the-art we propose a system that receives a dermatoscopy image and provides a diagnostic if the lesion is benign or malignant. This tool is composed with next modules: Preprocessing, Segmentation, Feature Extraction, and Classification. Preprocessing involves the removal of hairs. Segmentation is to isolate the lesion. Feature extraction is considering the ABCD dermoscopy rule. The classification is performed by the Support Vector Machine. Experimental evidence indicates that the proposal has 90.63 % accuracy, 95 % sensitivity, and 83.33 % specificity on a data-set of 104 dermatoscopy images. These results are favorable considering the performance of diagnosis by traditional progress in the area of dermatology

As sociedades enfrentam problemas cuja complexidade aumenta na razão direta do crescimento da população e dos impactos causados por uma demanda exponencial de recursos, energia, água e espaço físico na Terra. Embora seja desejável que cada cidadão contemporâneo participe ativamente na resolução dos problemas e na tomada de decisões coletivas, muitos se sentem incapazes de, ao menos, entender a magnitude das questões e correspondentes implicações em um mundo definitivamente imerso na ciência e na tecnologia. Assim, a concepção de tempo – especialmente a de tempo geológico – é crucial para fazer emergir a educação em ciência como instrumento capaz de permitir que todos, jovens e adultos, compreendam o mundo onde vivem. As taxas de derrubada de florestas tropicais na grande bacia hidrográfica amazônica aceleraram-se desde a metade do século XX, com alguns intervalos de redução. Os elementos revelam ser inadiável fortalecer e reintroduzir as Ciências da Terra na Educação, especialmente no Brasil. O conhecimento pode contribuir efetivamente para formar cidadãos conscientes e críticos, capazes de tomar decisões equilibradas e ponderadas sobre atividades humanas que envolvam ocupação e uso do ambiente, materiais naturais e fontes de energia. Neste artigo procuramos refletir sobre a importância do conhecimento geocientífico para formar cidadãos capazes de contribuir nos dias de hoje para plena adoção do conceito de desenvolvimento sustentável. Os dois elementos são fundamentais para que seja possível formular novas interseções e introduzir inovações no contexto da região Amazónica.
