Authors: Tchuifon Tchuifon Donald Raoul , Fu Hui-Zhen , Ho Yuh-Shan
Published: November 2017

Cameroon is one of the six countries of Central Africa with more than 20 000 000 residents. To characterize the Cameroon research performance, Cameroonians publications in the Science Citation Index Expanded during the period of 1936-2015, indexed in the Thomson Reuters SCI-EXPANDED database, were studied in this work. All documents of that period with Cameroon in the address field were included in the study. The document type, language, trend and collaborations were analyzed, as well as the output of different subject categories. Performances of countries, institutions and authors, including total, single, collaborative, first author, and corresponding author publications were also analyzed. Articles were analyzed by the scientific output and research performances of individuals, institutions and collaborative countries with Cameroon. Analyses included 8 457 articles (85 % of 10 591 Cameroonian publications). These bibliometric analyses of Cameroonian publications provided interesting insights concerning authors, institutions and collaboration patterns. Results showed that research in Cameroon was highly dependent on foreign collaborations, and the international collaboration was responsible for the increasing number of publications over the years. It was found that the articles with either first authors or corresponding authors from outside Cameroon got more citations than the others, and that the articles without any international collaboration had lower citations. The number of articles indexed by SCI-EXPANDED has seen an increase in terms of Cameroonian articles that is considerably greater that the increase in number of all articles in SCI-EXPANDED. Articles were more frequent than other types of publication and they were mostly in English. The University of Yaoundé I ranked top one in inter-institutionally collaborative articles, the rank of the total inter-institutionally collaborative articles, and the rank of first author articles and corresponding author articles. The University of Yaoundé I also was in an absolute leading position from 1970s to 2015, followed far away by the other institutions. The categories of tropical medicine, plant sciences, environmental and occupational public health, and infectious diseases, represented the largest number of published articles. Even though physics and chemistry dominated the ranking of the top 20 best Cameroonian authors, an independent mathematics article was the most cited, with 60 citations in 2015 to a Cameroonian author. The top three productive researchers were T. C. Kofane, B. T. Ngadjui, P. Woafo, all from University of Yaoundé I. France and the USA dominated the ranking of countries with strong scientific collaboration with Cameroon.

Authors: Juárez-Hernández Luis Gibran , Tapia-García Margarito
Published: November 2017

Coral reef fish may adapt to their habitat characteristics, and the particular system intrinsic factors, may cause different fish compositions and structures. The present study aimed to determine the variation in number of species, abundance and diversity of fish communities in Huatulco bays of San Agustin, Riscalillo, Chachacual, Cacaluta, Maguey, Organo, Violín and La Entrega, from Oaxaca, Mexico. Fish communities were characterized between January 2009 and December 2010, with the use of visual census techniques. A total of 351 transects (10 x 2.5 m) were made, and for each one we analyzed the ichthyofauna species number, abundance and diversity. The analysis showed that for all variables, the highest values corresponded to Maguey, La Entrega, Órgano and Violín bays, while the lowest values corresponded to the San Agustín, Riscalillo, Chachacual and Cacaluta bays. The study identified significant differences in diversity (Kruskal-Wallis=18.71, P= 0.0091), and in the composition and structure of fish communities in the bays (ANOSIM= 0.278, P= 0.001). We observed a relationship between the number of fish species and number of coral species (Spearman=0.591, P< 0.05), while no relationship was found between the coral reef area and the number of fish species or their abundances. The number of coral species and the patchy arrangement of the coral cover created habitats that are structurally more complex, which affects the number of fish species. In areas with developed tourist infrastructure, recreational aquatic activities were found to affect the ichthyofauna behavior, abundance and diversity. The new information of this study may contribute to create and improve management, conservation and protection strategies for this important area as a whole interconnected complex.
Spatio-temporal variation of roadkills show mass mortality events for amphibians in a highly trafficked road adjacent to a national park, Costa Rica
Authors: Arevalo Jose Edgardo , Honda Wataru , Arce-Arias Adrián , Häger Achim
Published: November 2017

Roads have detrimental impacts on wildlife populations around the world. Specifically, roads pose direct and indirect threats to wildlife by limiting dispersal movements or through vehicle-related mortality. The rate of wildlife mortality varies both in time and space depending on the landscape composition and the type and use of road infrastructure. The objective of this study was to investigate spatiotemporal variation of vertebrate mortality in a 4km segment of the 34 national road, adjacent to Carara National Park, Costa Rica. We conducted 81 roadkill surveys by car and bicycle from June 2010 to May 2011, georeferenced the locations of the kills and identified them to the lowest possible taxonomic level. We recorded a total of 4 709 road-killed animals of at least 58 species of vertebrates during the whole study. Amphibians accounted for 93.5 % of all the vertebrate losses and showed strong spatiotemporal variation of mass mortality events. Reptiles, especially snakes, were the second most affected taxon followed by mammals and birds. Relative mortality per day in the 4 km segment was 125.4 amphibians, 4.6 reptiles, 2.7 mammals, 1 bird and 0.46 undetermined. Road proximity to the border of the park, traffic volumes and lack of enforcement of speed limits may influence the high rate of roadkills found. We suggest the reinforcement of speed limits, wildlife crossing signage and the retrofitting of the existing culverts as under passes for animals to minimize vertebrate mortality at the road adjacent to Carara National Park.
A mentális rugalmasság idegtudománya
Authors: Janka Zoltán
Published: November 2017

Abstract:

Mental flexibility enabling shifts from the usual prepotent behaviour to new strategies and solutions is a significant factor in the successful adaptation to the changing environment. Components of mental flexibility comprise attention, salience detection, inhibition, working memory and switch processes which can be measured by neurocognitive tests. Data derived from examinations by the methods of cognitive neuroscience can be compared to the features, observed under resting state and during task performance, of brain structures and functions. Studying central nervous system correlates of mental flexibility by imaging, neurobiological, and pharmacological techniques revealed that certain cerebral regions (prefrontal cortex, anterior cingulate and insula, striatum, inferior parietal lobule) with their network connectivities, and some neurotransmitters (e.g. dopamine) have profound roles in this respect. Flexibility shares some similarities with artistic/scientific/everyday creativity and openness as a personality trait and this is also reflected in neurobiological parameters. According to precedents in art history, the public reception and acceptance of nonconform avant-garde artistic products are also dependent on flexibility and openness. Alterations of mental flexibility have been found in diseases (psychiatric and others), and in stress situations. Although flexible switch is generally considered as positive and beneficial, under certain conditions advantages might arise from keeping stability maintaining customs, conventions, and traditions.

A nervus alveolaris inferior védelmében: alsó bölcsességfogak coronectomiája. Irodalmi áttekintés
Authors: Szalma József , Lempel Edina
Published: November 2017

Abstract:

Coronectomy of lower impacted wisdom teeth is the partial removal of third molars, aiming to avoid inferior alveolar nerve injuries. The coronectomy procedure has several crucial points, such as the pulpal, periapical preoperative conditions of the tooth, the way of crown sectioning and decoronation, the wound closure and the length of patients’ follow up. In addition it is important to identify and manage possible intraoperative or postoperative complications correctly. According to the literature, the complication rate of coronectomy is usually lower, than that of total teeth removal, furthermore considering inferior alveolar nerve injuries, coronectomy is significantly the safer procedure. The aim of the authors was to review the relevant literature, defining the indications, contraindications and the correct implementation of the coronectomy and to demonstrate the causes and incidences of failures and complications. Further aim was to promote the domestic acceptance of this procedure. Orv Hetil. 2017; 158(45): 1787–1793.
Centrifuge modelling of traffic simulation on a construction waste layer
Authors: Lukiantchuki Juliana Azoia , de Oliveira Jose Renato Moreira da Silva , Pessin Juliana , de Almeida Marcio de Souza Soares
Published: November 2017

This paper describes a set of physical modelling laboratory tests on recycled construction and demolition waste (RCDW) in Paraná, Brazil. The physical modelling tests were conducted in the geotechnical beam centrifuge at the Federal University of Rio de Janeiro. The main idea of the tests was to run a wheel cyclically forward and backward on a strip over the RCDW layer applying a constant force corresponding to approximately 1 and 2 t in prototype scale. The force was kept constant through a specially designed control system that moves the actuator up and down in order to compensate for force variations due to horizontal movements. A total cell placed at the bottom of the RCDW layer, just above the middle of the track where the wheel runs, measured the increase in vertical stress. Comparison with a simplified analytical solution results in a slight underestimation of the total stress in the RCDW layer, whereas comparison with a classical elastic solution results in overestimation of the total stress. The permanent wheel track deformation due to the applied load was also measured during the cycles. The deformations observed in the centrifuge tests were higher than those obtained in the cyclic triaxial test.
Behaviour of geocell–geogrid reinforced foundations on clay subgrades of varying strengths
Authors: Biswas Arghadeep , Krishna A. Murali
Published: November 2017

This paper reports a laboratory model investigation performed on circular footing rested on geocell–geogrid reinforced foundations of different configurations. The model foundations comprised of geocell–sand mattresses (with an additional planer geogrid at the bottom) of varying thicknesses (H = 0·63–2·19D; where D is the footing diameter) placed on clay subgrades of different undrained shear strengths, ranged over very soft (cu = 7 kPa) to stiff (cu = 60 kPa). Responses of model tests have indicated significant influences of base-geogrid on the performance of geocell reinforced foundations, in terms of bearing pressure and surface deformation variations. An enhanced bearing capacity and uniform deformations at the foundation surfaces were noticed due to the inclusion of base geogrid. However, the beneficial effects were limited to shorter geocells (h ≤ 1·05D) and softer clay subgrades (cu ≤ 15 kPa); while, adverse effects were noticed for thicker geocells (h ≥ 1·57D) and foundations on comparatively stiff clay (cu ≥ 30 kPa). In general, improvements in bearing pressure were observed with an increase in footing settlement; about 40–70% enhancements in bearing pressures compared with geocell-alone systems, and maximum about 12-fold overall improvement (compared with corresponding homogeneous clay bed) were obtained in the experimental programme.

Authors: Robbins Bryant A. , van Beek Vera M. , López-Soto Jamie F. , Montalvo-Bartolomei Axel M. , Murphy John
Published: November 2017

A new type of laboratory test has been developed for measuring the local hydraulic conditions required for the progression of backward erosion piping, an internal erosion mechanism for water-retaining structures. The device consists of clear acrylic cylinders in which soil samples can be subjected to unidirectional, horizontal flow. The cylindrical sample shape ensures that the eroding pipe passes along the top of the sample allowing for pressure, pipe flow velocity and pipe geometry to be accurately measured in time. Experimental results are presented for tests conducted on two uniformly graded sands. The test results indicate that the critical hydraulic conditions for progression of backward erosion piping remain constant for all scales tested when defined over a distance of 10 cm upstream of the pipe tip. Additionally, the rate of pipe progression was found to be proportional to the seepage velocity upstream of the eroding pipe.

Preview of Ballast Water Treatment System Market Status
Authors:   University of Dubrovnik, Maritime department, Hasanspahić Nermin , Zec Damir
Published: November 2017

The International Convention for the Control and Management of Ships’ Ballast Water and Sediments was adopted in February 2004 and it was ratified by a sufficient number of countries in September 2016. The most important part of the Convention is Regulation D-2. One way to meet D-2 is to retrofit Ballast Water Treatment Systems (BWTS) on existing ships and their fitting on newbuildings. The market consists of the following stakeholders: shipowners, equipment manufacturers, shipyards, recognized organizations, laboratories for testing the efficacy of the BWTS and coastal countries’ administrations in charge for implementing Convention standards. In order to enable enough time to comply with the Convention, shipowners are granted maximum 5 year period, i.e. system retrofitting is connected to the first renewal of the International Oil Pollution Prevention certificate after September 2017. Some shipowners will postpone retrofitting for five years since they will renew IOPP certificates in advance, which is approved by many flag States and stated in their circular letters. More than 60 systems received flag State type approvals, but only few systems are approved by United States Maritime Administration (MARAD). That is one of the reasons why most of the shipowners are still waiting with planning and retrofitting, which leads to requests for more postponement. However, many manufacturers claim that they will be ready for increased demand for BWTS and will cope with and try to satisfy market demand by hiring additional work force, by expanding existing manufacturing facilities and maintain good cooperation with shipyards.

While the development of anti-vascular endothelial growth factor (anti-VEGF) as a therapy for neovascular age-related macular degeneration (AMD) was a great success, the pathologic processes underlying dry AMD that eventually leads to photoreceptor dysfunction, death, and vision loss remain elusive to date, with a lack of effective therapies and increasing prevalence of the disease. There is an overwhelming need to improve the classification system of AMD, to increase our understanding of cell death mechanisms involved in both neovascular and non-neovascular AMD, and to develop better biomarkers and clinical endpoints to eventually be able to identify better therapeutic targets—especially early in the disease process. There is no doubt that it is a matter of time before progress will be made and better therapies will be developed for non-neovascular AMD.

La identificación de factores de riesgo para cáncer de cuello uterino es determinante a la hora de establecer diagnósticos efectivos que, en un momento dado, pueden ser determinantes para salvar vidas. Desde esta perspectiva se realizó este estudio en una muestra constituida por 105 pacientes, que circunscribió a todas las mujeres que concurrieron a la consulta ginecológica en una campaña desarrollada por la Secretaría de Salud del Departamento del Atlántico. Se utilizaron dos instrumentos para la recolección de los datos: aquellos vinculados a cáncer de cuello uterino se registraron en un formulario elaborado para tales efectos. En el estudio fue considerada como variable dependiente el Cáncer de cuello uterino (CCU) y como variables independientes los factores relacionados con la paridad (Edad (ED), Número de Hijos Nacidos Vivos (NHV), Número de Hijos Nacidos Muertos (NHM), tipo de parto (TP) y tipo de embarazo (TE)). Finalmente, también se incluyeron las características de la conducta sexual [Enfermedades venéreas (EV): sífilis, herpes, gonorrea u otras]. De manera general se observa que el riesgo de tener cáncer de cuello uterino es mayor cuando aumenta el número de hijos en partos por cesárea y se ha perdido un hijo.

Published: November 2017

Background: Osteonecrosis of hip is a pathological condition that affects usually young adults. Articular surface replacement (ASR) is considered to be a viable option in young patients. The study was done with the aim to analyse and to recommend the management of osteonecrosis of femoral head in young patients by surface replacement of femoral head as ideal procedure.

Methods: The present study was conducted in 30 patients with osteonecrosis of the femoral head who attended to OPD at Santhiram Medical College and General Hospital, Nandyal, A.P during the period of April 2016 to September 2017. Articular surface replacement of the femoral head was the surgical procedure done in all the patients. The success of the treatment was analysed by Harris hip scoring.

Results: Maximum number of patients (60%) was below 40 years of age. Male dominance (77%) was seen in the study. According to Ficat and Arlet classification 12 cases (40%) were under the category of stage II-B and 18 cases (60%) were of stage III. Postoperatively about 90% of patients had postoperative Harris hip score of >80 points. Surgery was succeeded in 10 hips of stage II-B and 15 hips in stage III. According to Harris hip scoring excellent results were obtained in 15 (50%), good in 12 (40%), fair in 2 (6.67%) and poor result 1 (3.3%) patient.

Conclusion: The study concludes that the surface replacement is an anatomical hip arthroplasty with preservations of more than 70% of bone stock of femoral head and the ability of the patients to sit cross-legged and squat, which is the desire of the Indian population.

RESUMO - Fungos do gênero Curvularia são amplamente distribuídos ao redor do mundo, podendo estar associados a espécies vegetais, na forma saprofítica, endofítica ou como parasita. Espécies do referido gênero são responsáveis por diversas doenças em plantas cultivadas, causando principalmente manchas foliares. A correta identificação das espécies é importante para o conhecimento e manejo das doenças, sendo essas identificações baseadas principalmente em características morfológicas, como aspectos dos micélios, morfologia das hifas, formas e tamanho dos conídios. Entretanto, técnicas moleculares como a amplificação de genes específicos, além de análises do padrão de digestão de regiões ITS através de enzimas de restrição, têm contribuído para a identificação e diferenciação genética entre espécies. No presente trabalho foi realizada a caracterização morfológica e molecular de isolados de Curvularia oriundos de plantas de milho infectadas. Os isolados foram agrupados de acordo com a identificação morfológica e molecular, sendo que todos apresentaram o mesmo perfil de amplificação do DNA. As técnicas morfológicas e moleculares possibilitaram a caracterização de uma única espécie, Curvularia lunata.Palavras–chave: Zea mays L., Curvularia lunata, morfologia, DNA, perfil de restrição.MORPHOLOGICAL AND MOLECULAR IDENTIFICATION OF Curvularia sp.CAUSAL AGENT OF CORN LEAF STAINABSTRACT - Fungi of the genus Curvularia are widely distributed around the world and may be associated with plant species, in the saprophytic, endophytic or parasitic form. Species of this genus are responsible for several diseases in cultivated plants, causing mainly foliar stains. The correct identification of the species is important for the diseases knowledge and management, being these identifications based mainly on morphological characteristics as aspects of the mycelia, conidia forms and size, hyphae morphology. However, molecular techniques such as the amplification of specific genes, as well as digestion pattern analyzes of ITS regions through restriction enzymes, have contributed to the identification and genetic differentiation between species. In the present study, the morphological and molecular characterizations of Curvularia isolates from infected corn plants were realized. The isolates were grouped according to the morphological and molecular identification, all of which presented the same DNA amplification profile. Morphological and molecular techniques allowed the characterization of a single species, Curvularia lunata. Keywords: Zea mays L. Curvularia lunata, morphology, DNA, restriction profile.
An Empirical Examination of the Relationship Between Dating Abuse and Entitlement Within a College Population
Authors: Warrener Corinne D. , Tasso Anthony
Published: November 2017

Although partner abuse is well established as destructive societal problem, partner abuse among adolescents and young adults has only recently gained attention. Entitlement is a concept regularly evoked in the dating abuse literature. Much of the literature on dating partner abuse focuses on adolescent/young adult victimization, whereas perpetration is less well understood. This study examined sense of entitlement and its relationship to various types of abuse, including economic, emotional, physical, and sexual. Sense of entitlement was positively correlated with all types of abuse and was a better predictor of abusive behaviors than other variables in the regression model. Implications address how, including how assessing and addressing entitlement can enhance both partner abuse prevention and intervention efforts.

Past studies on the relationship between dividend policy and firm performance continue being an unresolved predicament with few studies interrogating the causality relationship between financial performance and dividend policy. The purpose of this study was to establish the nature of relationship between financial performance and dividend policy of firms listed at the Nairobi securities exchange. The study applied positivism research philosophy and descriptive causal research design. The study was anchored on hypothetical view that the relationship between financial performance and dividend policy of firms listed at the Nairobi securities exchange is not significant which was tested against a sample size of 31 firms listed at the Nairobi securities exchange selected using purposive sampling technique. The research findings were as follows: There was a statistically significant direct association between return on equity and dividend policy. This implies that as firm profitability improve; a corresponding proportionate change in dividend payout ratio is initiated by management. In addition, it was established that there was a statistically significant positive linkage between operating cash flows and dividend policy which denotes that as cash flow levels from operating activities change, dividend payout ratio will change in the same direction leading to increased distribution of cash dividend to investors. Also, a statistically significant direct connection between price earnings and dividend policy was established. This relationship shows that increase in share market value positively prompts increased dividend payout ratio whereby the management follow a more acceptable dividend policy by the shareholders. However, market to book value depicted a weak insignificant inverse relationship with dividend policy and was dropped. In general it was concluded that the link between financial performance and dividend policy of firms listed at the Nairobi securities exchange was significant. The study outcome augment existing knowledge on financial performance and dividend policy for it is evident that firms with ability to generate income directly influence dividend payout ratio and therefore, top management should focus on financial performance strategies and not dividend policy which is irrelevant. Regulatory bodies such as Capital Market Authority and Centre for Corporate Governance use these research findings to improve their financial viability assessment approach of firms listed at the Nairobi securities exchange.

In general it was concluded that the link between financial performance and dividend policy of firms listed at the Nairobi securities exchange was significant. The study outcome augment existing knowledge on financial performance and dividend policy for it is evident that firms with ability to generate income directly influence dividend payout ratio and therefore, top management should enhance financial performance and not dividend policy which is irrelevant. Cash holdings intervenes this relationship hence the level of cash balances maintained by the firm explain more on the reason why some firms pay more dividend on increase of profitability levels while others does not. Regulatory bodies such as Capital Market Authority and Centre for Corporate Governance use these research findings to improve their financial viability assessment approach of firms listed at the Nairobi securities exchange.

Authors: V. N. Eboatu,
Published: November 2017

This study investigated the impact of the practice of class repetition and mass promotion of failed JSS1 students on their academic achievement in Anambra State. The causal comparative or ex-post-facto type of the survey research design was adopted with four research questions and four hypotheses guiding the study. The population of the study consisted of all failed Junior Secondary School (JSS1) students in Anambra State secondary schools in the base year (2004/2005), from which a sample of 636 was drawn. A researcher designed form was used to collect the students’ results. The statistical analysis of frequencies, range of scores, percentages and Pearson Product Moment Correlation were used to answer the research questions, while t-test was used to test the hypotheses. Findings of the study, among other things, show that the repeated students made a significant positive change in their repeated JSS1 and that the repeated students’ results were significantly better than those of the mass promoted group JSS2 results. Based on the findings, the researcher recommends that educational policy makers adopt an eclectic promotion policy that will enable the school managers repeat students in cases where it is felt that class repetition will enhance students’ learning and academic achievement.

The main aim of this study is to empirically examine ,investigate and test the relationship between unemployment rate and economic growth within Jordanian economy over the period of time (1982-2016), in order to examine the validity of Okun’s law, which suggests a negative relationship between unemployment rate and economic growth, several economic methods are employed by using descriptive statistics, as well as some econometric tests, in order to analyze the variables under study . The empirical results of this study show a negative relationship between unemployment and GDP in the period 1982-2016 in Jordanian economy, which is consistent with Okun’s law. In other word, this study offered an additional empirical evidence to confirm the validity of the Okun’s law in the case of Jordan over the period 1982-2016.So any attempt to increase economic growth through some economic policies such as expansion in spending would reduce unemployment rate, where the Okun’s coefficient of GDP with respect to unemployment rate is- 0.004, such that an increase of 100 million Jordanian Dinars in the Real GDP will cause 40% decrease in the unemployment rate, which is about half percent in unemployment rate in the next. The findings of this thesis may help economists and policymakers when adapting policies in order to adjust unemployment level in the economy.

Arquitetura Rural e o espaço não-urbano
Authors: Argollo Ferrão André Munhoz de
Published: November 2017

Este trabalho enfoca o ambiente construído rural a partir de diversas áreas do conhecimento, procurando integrar conceitos e caracterizar o que se poderia chamar de “espaço não-urbano”. No campo da Engenharia, o Planejamento Regional já reconhece os aspectos intrínsecos ao espaço não-urbano. No campo da Arquitetura e Urbanismo, o ambiente rural chama a atenção para o patrimônio cultural rural, sua sustentabilidade e valorização. Empreendimentos de turismo no espaço rural, assim como as áreas de construções rurais e ambiência, no âmbito das ciências agrárias, além da tradicional área de assistência técnica e extensão rural mostram-se cada vez mais abertas aos estudos sobre os diversos aspectos do ambiente construído rural com base no que propomos chamar “Arquitetura Rural”, que assim poderia ser considerada uma área de estudos capaz de abranger todos os aspectos relacionados ao ambiente agrícola construído, voltados direta ou indiretamente para a produção, no âmbito dos diversos complexos produtivos que compõem o Complexo Agro-industrial-comercial. Para além dos aspectos intrínsecos ao ambiente agrícola, a Arquitetura Rural propõe um enfoque transdisciplinar para os estudos de paisagem e ordenação territorial, tratando principalmente do chamado “espaço não-urbano” – aqui denominado “espaço nu” – distinto em sua essência do “espaço urbano” e também do “espaço rural”.

Orientalisme Romantis: Imajinasi Tentang Timur Sebelum Edward Said
Authors: Irfanullah Gumillar
Published: November 2017

Orientalism is a 1978 book by Edward W. Said, in which Said studies the cultural representations that are the bases of Orientalism, the West's patronizing perceptions and fictional depictions of "The East" â€” the societies and peoples who inhabit the places of Asia, North Africa, and the Middle East. Orientalism, the Western scholarship about the Eastern World, was and remains inextricably tied to the imperialist societies who produced it, which makes much Orientalist work inherently political and servile to power, and thus intellectually suspect.Orientalism is the exaggeration of difference, the presumption of Western superiority, and the application of clichÃ©d analytical models for perceiving the Oriental world. As such, Orientalism is the source of the inaccurate, cultural representations that are the foundations of Western thought and perception of the Eastern world, specifically about the region of the Middle East. The principal characteristic of Orientalism is a â€œsubtle and persistent Eurocentric prejudice against Arabâ€“Islamic peoples and their cultureâ€, which prejudice derives from Western images of what is Oriental (cultural representations) that reduce the Orient to the fictional essences of â€œOriental peoplesâ€ and â€œthe places of the Orientâ€; such cultural representations dominate the communications (discourse) of Western peoples with nonâ€“Western peoples. Orientalism proposes that much of the Western study of Islamic civilization was an exercise in political intellectualism; a psychological exercise in the self-affirmation of â€œEuropean identityâ€; not an objective exercise of intellectual enquiry and the academic study of Eastern cultures. Therefore, Orientalism was a method of practical and cultural discrimination that was applied to non-European societies and peoples in order to establish European imperial domination.
Simultaneous Ipsilateral Dislocation of the Hip and the Knee
Authors: Arenas Miquelez Antonio , Familiari Filippo , Arbeloa Lucas , D’Arrigo Azzarelli Andrea
Published: November 2017

Case:

A patient was struck by an agricultural vehicle and sustained ipsilateral hip and knee dislocations. Closed reduction of the hip was accomplished in the emergency department; the patient required general anesthesia in the operating room to reduce the knee dislocation. Nonoperative treatment was used for both injuries, with a good long-term outcome.

Conclusion:

Simultaneous ipsilateral hip and knee dislocations are rare and complex injuries that usually result from high-energy trauma. In order to avoid severe neurovascular complications, they need prompt management. Nonoperative treatment followed by an intensive rehabilitation program should be considered as an alternative treatment to surgery in older patients with a low-demand lifestyle.
