The importance of medication reviews in a primary care setting
Authors: Shepherd Alison Burton
Published: June 2018

Medication reviews are important in primary care and help prevent adverse reactions from medications, improve the medical condition of the patient and reduce the usage of medicines to save money in the NHS.

A medication review can be conducted by a suitably qualified nurse, doctor or pharmacist either as part of a meeting or medical consultation with a patient. Where possible, it is suggested that medication reviews be tailored to suit individual patient needs and held in conjunction with medicine reconciliation as both of these factors are important in prevention of hospital admission. The aim of this article is to identify which patient groups may benefit from a medication review and will provide insight into the process using an anonymised example from clinical practice.

Published: June 2018

Quantum chemical calculations were performed on amitrole used as herbicide in agriculture to investigate its interaction with humic substances which are the main components of soil organic matter. They contain carboxylic, phenolic, amine and quinonic groups as well as specific structural configurations. Global and local reactivity have been studied to predict reactive centers and to determine the favorable site for interaction with surface. The results suggest us that hydrogen bonds are formed between this compound and the amino acids of soil organic matter. The effect of water as solvent is considered since adsorption of pesticide commonly occurs in aqueous environment.

Authors: Masyithah Z. , Ginting A.
Published: June 2018

The present study deals with the oxidative cleavage of oleic acid (OA) using hydrogen peroxide and tungstic acid as a catalyst to produce azelaic acid. A two-step method has been expanded for the optimization of a new route of azelaic acid synthesis with the addition of sodium hypochlorite as the co-oxidation. The Central Composite Design (CCD) and Response Surface Methodology (RSM) were performed to optimize the production of azelaic acid. The interaction effect among catalyst concentration, substrate molar ratio and temperature were done for optimization the conversion of oleic acid. Maximum oleic acid conversion of 99.11% was reached at substrate molar ratio of 4/1 (H2O2/OA), a catalyst concentration of 1.5% (w/wOA) and temperature of 70oC. The GC analysis shows that the yield of azelaic acid is 44.54% and pelargonic acid is 34.12%. These results indicate that the proposed process show a good strategy for the synthesis of azelaic acid from oxidative cleavage of oleic acid.

Published: June 2018

Abstract. This study assesses greenhouse gas (GHG) mitigation options for the agriculture sector. The Long-range Energy Alternatives Planning (LEAP) model was used to develop a framework to assess future trends in energy demand and associated GHG emissions for the agriculture sector and to assess various GHG mitigation options associated with energy consumption. A business-as-usual (reference) scenario and 32 GHG mitigation scenarios were developed for the years 2009-2050 using the LEAP model. A case study for Alberta, Canada, was conducted. In the model, GHG mitigation scenarios were developed for the energy demand side (e.g., farm machines, farm transportation, lighting, and ventilation) based on efficiency improvements and the use of renewable energy. The mitigation scenarios were divided into two planning horizons based on technology penetration: slow penetration (2009-2050) and fast penetration (2009-2030). For each planning horizon, 16 scenarios were assessed. Of all farm machines, efficient diesel tractors have the highest GHG mitigation potential: 12.35 MT of CO2 equivalent by 2050 and 4.7 MT of CO2 equivalent by 2030. In addition, GHG abatement cost curves show that biodiesel tractors and efficient diesel tractors have the highest GHG mitigation potential, with attractive abatement costs of -$62 and -$11 tonne-1 of CO2 mitigated by 2050, respectively. Keywords: Abatement cost, Agriculture sector, Energy efficiency, GHG mitigation, LEAP model.
Carbon Footprint Assessment of a Large-Scale Pig Production System in Northern China: A Case Study
Authors: Zhou Yuanqing , Dong Hongmin , Xin Hongwei , Zhu Zhiping , Huang Wenqiang , Wang Yue
Published: June 2018

Abstract. China raises 50% of global live pigs. However, few studies on the carbon footprint (CF) of large-scale pig production based on China’s actual production conditions have been carried out. In this study, life cycle assessment (LCA) and actual production data of a typical large-scale pig farm in northern China were used to assess the greenhouse gas (GHG) emissions or CF associated with the whole process of pig production, including feed production (crop planting, feed processing, and transportation), enteric fermentation, manure management, and energy consumption. The results showed a CF of 3.39 kg CO2-eq per kg of live market pig and relative contributions of 55%, 28%, 13%, and 4% to the total CF by feed production, manure management, farm energy consumption, and enteric fermentation, respectively. Crop planting accounted for 66% of the feed production CF, while feed processing and transportation accounted for the remaining 34%. Long-distance transport of semi-raw feed materials caused by planting-feeding separation and over-fertilization in feed crop planting were two main reasons for the largest contribution of GHG emissions from feed production to the total CF. The CF from nitrogen fertilizer application accounted for 33% to 44% of crop planting and contributed to 16% of the total CF. The CF from the transport of feed ingredients accounted for 17% of the total CF. If the amount of nitrogen fertilizer used for producing the main feed ingredients is reduced from 209 kg hm-2 (for corn) and 216 kg hm-2 (for wheat) to 140 kg hm-2 (corn) and 180 kg hm-2 (wheat), the total CF would be reduced by 7%. If the transport distance for feed materials decreased from 325 to 493 km to 30 km, along with reducing the number of empty vehicles for transport, the total CF would be reduced by 18%. The combined CF mitigation potential for over-fertilization and transport distance is 26%. In addition, the use of pit storage, anaerobic digestion, and lagoon for manure management can reduce GHG emissions from manure management by 76% as compared to the traditional practice of pit storage and lagoon. This case study reveals the impact of planting-feeding separation and over-fertilization on the CF of the pig supply chain in China. The manure management practice of pit storage, anaerobic digestion, and lagoon is much more conductive to reducing the CF as compared to the traditional practice of pit storage and lagoon. Keywords: Greenhouse gas, Life cycle assessment, Mitigation, Pig.

Grey theory based evaluation of importersâ€™ strategies for hedging the price risk in the Tanzanian oil supply chain: a focus on derivative products
Authors: P. Massami Erick , M. Manyas Malima , M. Myamba Benitha
Published: June 2018

The landed cost for oil products in local markets is very often affected by the fluctuation of price related to the international purchasing from oil markets. As a result, oil products are primarily procured via term contracts i.e. derivatives as wholesalers are typically loath to rely heavily on spot supplies as these may be unreliable and exhibit high price volatility. In this study, we apply Grey Theory to evaluate the derivatives based strategies of the Tanzanian oil products imports for hedging the price risk in the local market. After comprehensive evaluation, we find that the applicability of oil derivatives by the Tanzanian importers is high. Thus, the government (i.e. Ministry of Finance and Planning, Ministry of Trade and Industry) and other stakeholders have the obligation to continue bringing awareness on the benefits of the derivative instruments in the purchasing of oil products, which ultimately upon application would bring a relief to all consumers of the oil products in the country. Moreover, as the grey theory can deal with vague and incomplete data, the proposed model can be applied as an evaluation tool for quantifying qualitative data in any industry.Â Â

Authors: Radhika Sajja , Chaparala Aparna
Published: June 2018

Optimization is necessary for finding appropriate solutions to a range of real life problems. Evolutionary-approach-based meta-heuristics have gained prominence in recent years for solving Multi Objective Optimization Problems (MOOP). Multi Objective Evolutionary Approaches (MOEA) has substantial success across a variety of real-world engineering applications. The present paper attempts to provide a general overview of a few selected algorithms, including genetic algorithms, ant colony optimization, particle swarm optimization, and simulated annealing techniques. Additionally, the review is extended to present differential evolution and teaching-learning-based optimization. Few applications of the said algorithms are also presented. This review intends to serve as a reference for further work in this domain.
Biomechanical characteristics of Taekwondo athletes: kicks and punches vs. laboratory tests
Authors: Buśko Krzysztof , Nikolaidis Pantelis T.
Published: June 2018

Study aim: The aim of the study was to examine biomechanical characteristics of taekwondo athletes comparing kicks and punches with laboratory tests of muscle strength and power. Material and methods: Six male taekwondo athletes participated in this study. Measurements of maximal punching with the rear hand (hook and straight punches) and kicking (Apdolio and Dwit Chagi) force were performed on a boxing dynamometer. Also, the following laboratory tests were performed: jump height and power output in counter movement jump (CMJ) and spike jump (SPJ), muscle strength for 10 muscle groups and force-velocity (F-v) relationship. Results: Mean maximal straight and hook punching forces were 1659.2 ± 254.2 N and 1843.8 ± 453.3 N, respectively. Maxi­mal Apdolio rear leg, Apdolio lead leg and Dwit Chagi rear leg kicking forces were 3541.3 ± 1130.3 N, 3205.3 ± 965.1 N and 3568.0 ± 1306.0 N, respectively. The heights of jumps were 0.501 ± 0.040 m (CMJ) and 0.554 ± 0.034 m (SPJ). A strong cor­relation between the maximal force of a punch and maximal joint torques was observed. Conclusions: The values of kicking forces developed in a simulated fight were lower than the forces developed in the test of individual kicks. Strong relationships were observed between leg power developed in the SPJ and force of individual Apdolio kicks performed with the lead (r = 0.87, p < 0.05) and rear leg (r = 0.74). Based on these findings, it was concluded that maxi­mal joint torques and height of the SPJ could be used as a proxy of kicking force.
Improving energy efficiency of supercomputer systems through software-aided liquid cooling management
Authors: Januszewski Radosław , Różycki Rafał , Waligóra Grzegorz
Published: June 2018

Many fields of modern science rely more and more on the immense computing power of supercomputers. Modern, multi-thousand node systems can consume megawatts of electrical energy in highly uneven manner, challenging the data center infrastructure, both power and cooling coils. The traditional way of managing the infrastructure makes each subsystem of a data center (e.g. cooling) independent from all other in the way it relies only on local sensors to manage the infrastructure. The erratic nature of computing in a large data center makes this approach suboptimal. In the paper we show that by challenging the traditional split between the infrastructure and the computing equipment, one can gain significant boost in energy efficiency of the entire ecosystem. A solution that predicts cooling power demand basing on the information from a supercomputer resource manager, and then sets up the parameters of the cooling loop, is presented along with potential benefits in terms of reduction of the power draw.
Architecture Enabling Adaptation of Data Integration Processes for a Research Information System
Authors: Solodovnikova Darja , Niedrite Laila , Niedritis Aivars
Published: June 2018

Today, many efforts have been made to implement information systems for supporting research evaluation activities. To produce a good framework for research evaluation, the selection of appropriate measures is important. Quality aspects of the systems’ implementation should also not be overlooked. Incomplete or faulty data should not be used and metric computation formulas should be discussed and valid. Correctly integrated data from different information sources provide a complete picture of the scientific activity of an institution. Knowledge from the data integration field can be adapted in research information management. In this paper, we propose a research information system for bibliometric indicator analysis that is incorporated into the adaptive integration architecture based on ideas from the data warehousing framework for change support. A data model of the integrated dataset is also presented. This paper also provides a change management solution as a part of the data integration framework to keep the data integration process up to date. This framework is applied for the implementation of a publication data integration system for excellence-based research analysis at the University of Latvia.

Published: June 2018

Flavonoid structures, found in nature or obtained by synthesis, may be very complex. These Recommendations provide a guide for flavonoid aglycone names. This will also allow the construction of the names for their polyglycosylated species with clarity and conciseness. A joint working party of IUPAC/IUBMB members has prepared these recommendations, which establish rules for the general nomenclature of flavonoids, providing examples of acceptable trivial names, and names derived from trivial names, together with semi-systematic and fully systematic names that follow the published IUPAC recommendations.

Here, I am particularly dealing with the question of human person and their relations with others, as well as the humanities. I show globalization, the growth of cancerous mass culture and secularization as a background of the crisis of civilization. In this context, I try to show the importance of Chiara Lubich and her work.
From the Charism to Action in Educational, Organizational and Social Aspect on the Example of Religious Congregations Formed in Poland in the Nineteenth/Twentieth Century
Authors: Opiela Maria Loyola
Published: June 2018

The charism of the congregation expresses some selected and implemented aspect of the mystery of Christ and the life of the Church, and its specificity is the determinant of the identity of the institute. From it follows a specific pattern of relationship with God and with the environment, the characteristics of spirituality, various forms of the practice of the evangelical counsels, business forms and certificates of members, leading to the formation of a particular tradition. An important dimension in the formation and development of religious congregations are the socio-cultural conditions. In business meetings is visible specific aspect resulting from its own charisma, but its implementation are multiple activities forming an integral approach to the needs of people and the environment. Thanks to the dynamics of dialogue educational activities, organizational and social formed in the nineteenth/twentieth century in Poland, active congregations today continues and is still valid.
Living the Threshold. The Kairos of World Person and New Perspective for Hospitality
Authors: Almeida Gabriel Antunes Ferreira de
Published: June 2018

Starting from the analysis of a phenomenological reading of the parable of the Good Samaritan and arriving at the idea of the World Person in Chiara Lubich, this article will discuss two topics: union in difference and the model of the neighbor in the Gospel. For Christians this is the confirmation that the meeting with the stranger is possible. Christ founded a community that co-exists with the stranger. It is within this path that the intuition the figure of the World Person in Chiara Lubich arises. In the tension between interpretation and Truth, Lubich puts the question: was there anyone that went through the trial of doubt about the Truth, but has been able to create a new world? She says that was Jesus Forsaken, who opens up the possibility of differentiation without exclusion.
Toward a Transdisciplinary Integration of the Health Disciplines: The Case of the Fibromyalgia Syndrome
Authors: Giusti Emanuele Maria
Published: June 2018

Fibromyalgia is a chronic pain disorder with a multifaceted nature and its biological, psychological and social aspects are strongly interconnected. Therefore, the integration of the different health disciplines is strongly recommended for its care. There is a growing number of interventions based on this principle but each of them is heterogeneous with regards to how the included disciplines are integrated with each other. With this regards, multidisciplinary and interdisciplinary programs are distinguished. The former are organized in order to treat the various aspects of the syndrome using different perspectives and their various treatment components are usually provided separately by the different care providers. Conversely, interdisciplinary treatments are planned in order to foster a dialogue between the operators by providing a joint conduction of the treatment or scheduling plenary discussions about the cases. In the field of chronic pain, some authors are suggesting to move beyond these approaches and to plan transdisciplinary treatments, which would allow the professionals to move across their disciplinary boundaries. Although no examples of these interventions have been proposed for the treatment of fibromyalgia, there is a visible trend in the literature toward more holistic forms of care.
A green determination of an equilibrium constant: teaching new skills
Authors: Bachofer Steven J. , Lingwood Mark D.
Published: June 2018

The spectroscopic determination of an equilibrium constant is a classic experiment in the general chemistry laboratory curriculum. Here we describe a new version of this experiment, incorporating green chemistry practices into the general chemistry lab curriculum and directly teaching students about the principles of green chemistry. This lab studies the formation of the iron(III) salicylate complex ion, which is a more benign chemical system than the traditional iron(III) thiocyanate complex. A microtiter plate reader is used to reduce sample volumes, also giving students important experience using research-grade instrumentation. In addition, students gain more experience using adjustable manual micropipettors. Students responded positively to the lab, appreciating the green nature of the lab and the introduction of the plate reader, and student comments suggested that this lab successfully introduces green chemistry concepts to the general chemistry curriculum.

Gehen Sanktionen mit einem höheren Stigmabewusstsein bei Arbeitslosen einher?
Authors: Gurr Thomas , Unger Stefanie , Jungbauer-Gans Monika
Published: June 2018

Das Stigmabewusstsein Arbeitsloser ist ein bisher weitgehend unerforschtes Feld. Dieser Artikel untersucht unter Verwendung von quantitativen und qualitativen Daten (Mixed Methods) den Zusammenhang zwischen dem Erleben von Sanktionen im Vermittlungsprozess und dem Ausmaß, in dem die Betroffenen glauben, aufgrund von Arbeitslosigkeit stigmatisiert zu sein. Die quantitative Analyse zeigt, dass Sanktionen nicht mit dem Stigmabewusstsein aufgrund von Arbeitslosigkeit korrelieren. In anschließenden, komplementären Analysen von qualitativen Daten werden vier Mechanismen herausgearbeitet, die erklären können, warum erwartete signifikante Korrelationen zwischen der konkreten Sanktionierung und dem Stigmabewusstsein ausbleiben. Ein zentraler Faktor ist hier die weite Verbreitung und ständige Androhung von Sanktionen.
New Book Chronicle
Authors: Lawrence Dan
Published: June 2018

For this issue of NBC, we investigate a range of different approaches to the archaeology of ritual. The attribution of unexplained phenomena to ritual practice is something of a cliché in public perceptions of archaeology (just try googling ‘ritual archaeology cartoon’!), and even within the discipline there are those who remain sceptical that we can ascend Hawkes's ladder of inference (1954) to such dizzy heights. Yet several recent books coming in to the Antiquity office show how both theory and method are advancing our understanding of this complex concept. Sparked by the publication of two major volumes from Cambridge, we here take the pulse of the archaeology of ritual, and find it in rude health.

Diniz, R, Del Vecchio, FB, Schaun, GZ, Oliveira, HB, Portella, EG, da Silva, ES, Formalioni, A, Campelo, PCC, Peyré-Tartaruga, LA, and Pinto, SS. Kinematic comparison of the roundhouse kick between taekwondo, karate, and muaythai. J Strength Cond Res 35(1): 198–204, 2021—The roundhouse kick (RHK) is frequently executed in taekwondo, karate, and muaythai because of its high technical effectiveness during combat. The purpose of this study was to compare kinematic characteristics during RHK performance between taekwondo, karate, and muaythai athletes. Forty-seven male athletes (25.5 ± 4.7 years, 1.75 ± 0.1 m, and 75.8 ± 11.5 kg) volunteered to participate (taekwondo: 17; karate: 15; and muaythai: 15). Self-selected distance from target, mean and peak fifth metatarsus linear velocity (LV5mean; LV5peak), mean and peak hip (HAVmean; HAVpeak) and knee (KAVmean; KAVpeak) angular velocities, as well as target linear acceleration (TLA) were analyzed with a 3D video motion analysis system. Comparisons between modalities were performed with 1-way analysis of variances and Bonferroni's post hoc test (α = 0.05). Self-selected distance was lower in muaythai compared with taekwondo and karate (p < 0.001). Also, karate had greater LV5mean compared with muaythai (p = 0.001), and muaythai showed higher HAVmean than karate (p = 0.011). In addition, HAVpeak was greater in muaythai than in taekwondo and karate (p < 0.001). No differences were found for KAVmean, KAVpeak, and TLA. Although it is similarly described between modalities, RHK showed distinct kinematic characteristics between taekwondo, karate, and muaythai. Based on these results, coaches and athletes can improve their RHK technique according to the specificities of each combat sport. Specifically, it is suggested that combat strategies should aim to increase the distance from the opponent during combat for muaythai athletes, whereas taekwondo and karate athletes should focus on decreasing it.
Does Sea-Water pH Influence Carbon and Oxygen Isotopic Composition of Modern Planktic Foraminiferal Species Globigerina Bulloides in South West Indian Ocean?
Authors: N. Khare
Published: June 2018

Present study aims to understand the possible influence of changing sea-water pH on the isotopic composition (δ18O and δ13C) of modern planktic foraminiferal shell in twenty three surface sediment samples (including grab and core tops of piston and gravity cores), collected along a north-south trending transect in the western Indian Ocean. The results, though initial indicate that the isotopic values (δ18O and δ13C) in general increase as the sea-water becomes less alkaline. It suggests that the sea-water pH also appears to influence isotopic values of planktic foraminiferal species G. bulloides, besides other factors influencing isotopic values in planktic foraminiferal shell.
Investigating Relationships between Engineering Properties of Various Rock Types
Authors: Mehmet Sari
Published: June 2018

In the literature on rock mechanics several authors have proposed different constants and empirical equations for the physical and mechanical properties of various rock types. This is because researchers usually base their results on the limited number of test samples and/or lithological units. The research presented here has been primarily performed to solve this variation problem. It makes sense to have a general expression for all types of rocks. To accomplish this, a considerable amount of data comprising 4,991 datasets was collected through an extensive literature review. The results were statistically analyzed to determine the range, mean, standard deviation for each investigated rock property. The physical and mechanical properties of the rocks were also plotted against each other in order to estimate one property from the other. The correlation coefficients and best-fit equations were determined by the least squares curve fit method. Usually good correlations were found between index tests, and physico-mechanical properties. At the end, various regression equations are proposed particularly applicable to the whole rock types.
Quantification of Condensed Tannins in Sainfoin Powder (Onobrychisviciifolia) by FT-NIR Spectroscopy
Authors: Cédric Camps  , Werne Steffen  , Mélanie Quennoz  , Xavier Simonnet  , Céline Gilli
Published: June 2018

Models based on FT-NIR spectroscopy and PLS-regressions were developed over three harvest years to determine the condensed tannins contents (CT, %(w/w)) in sainfoin powders. The three data sets corresponding to the three harvest years were used as calibration and then validation sets, successively. Finally, a global model gathering all the three years data sets has been developed. The developed models predict CT in a range of 2.06 to 11.28 %(w/w). The accuracy of the models depended on the range of CT-values of the calibration and validation sets. Finally, it was possible to predict the CT with a SEP-value lower than 0.5% (w/w) and R2-value higher than 0.9. In the present study, some of the PLS-parameters such as bias, slope and SEP have been statistically evaluated using the international standard ISO 12099:2017. The final global model was very promising since bias was not significantly different from 0, the slope was not significantly different from 1, and obtained SEP was 0.49% (w/w) while the calculated SEP-limit was 0.47% (w/w). The presently developed model was robust over the three years and the global model presented very interesting values. Such approach would be very useful to develop a new quantitative, rapid and low cost method to assess the CT of sainfoin powders. This method will allow us to free ourselves from the traditional chemical method that consumes time, money and chemicals.

Published: June 2018

En este trabajo de investigación presentaremos la "Elección de portafolios óptimos de activos con y sin riesgo", donde planteamos un modelo de optimización de portafolios eficientes basado en la teoría de Markowitz (Activos con Riesgos), quien ganó el Premio Nobel de Economía en 1990 por sus aportes al análisis de portafolios de inversión y a los métodos de financiación corporativa. Markowitz basándose en su teoría, define que para un rendimiento dado el riesgo que le deparan sea mínimo, éste modelo es el más eficiente a la hora de reducir riesgos. Por otro lado, si optamos por un portafolio óptimo de acivos sin riesgo nos apoyaremos en el Modelo de Sharpe, que establece una fijación de precios de activos financieros, en el cual un inversionista puede elegir una exposición al riesgo a través de una combinación de valores de renta fija y un portafolio de renta variable.

DENTAL EROSION IN GASTRO-ESOPHAGEAL REFLUX DISEASE. A SYSTEMATIC REVIEW
Authors: Picos Andrei , Badea Mândra Eugenia , Dumitrascu Dan Lucian
Published: June 2018

The growing interest reflected in the studies on dental erosion is justified by the severe health problems it entails, i.e. esthetic, phonetic, masticatory disturbances and pulp complications. Most studies investigate the prevalence of dental erosion in adults and children, the severity of lesions and etiopathogenetic factors.Background and aim. Dental erosions (DE) are one of the extraesophageal complications of gastroesophageal reflux disease (GERD). An increasing amount of papers shed light on this topic. We carried out a systematic review on the association between GERD and DE.Methods. We studied the association between DE and GERD in adults and children. The search for published studies was performed in PubMed using search terms “dental erosion” and “gastro-esophageal reflux disease”. References published since 2007 were included and a systematic review was carried out. Articles not assessing DE in GERD patients were excluded, and also case presentations and articles in languages of limited circulation. The prevalence of DE in patients with GERD, extrinsic and intrinsic etiological factors of DE and the severity of dental erosion lesions were analyzed.Results. A total of 273 articles were found, 10 studies being retained for analysis. Correlations between DE and GERD, namely the prevalence and severity of dental erosion in GERD patients, were investigated. DE prevalence was between 10.6% - 42%, median 25.5%. Mean values of DE prevalence were 48.81% in GERD patients, compared to 20.48% in non-GERD controls. Comparative values of DE frequency in adults with GERD was 38.96%, compared to 98.1% in children with GERD.Conclusions. DE is a condition associated with GERD. DE prevalence is higher in GERD patients. Intrinsic pathogenetic factors with direct action on the hard dental tissues are GERD, while extrinsic factors are represented by diet. Among the patients diagnosed with GERD, youth under the age of 18 had a higher frequency compared to adults.

Background: Lung Cancer (LC) is one of the most common cancers in the international arena. The aim of this study was to investigate the geographical distribution of LC incidence and mortality in the world in 2012, as well as the trend of incidence and mortality of LC during 1975 to 2010 based on the gender.

Methods: In the present study, we extracted the information on the incidence and mortality of LC in 184 countries from the International Agency for Research on Cancer (IARC) (Project GLOBOCAN, 2012). The present study categorized and presented the information on the Age-Standardized Incidence Rate (ASIR) and Age Standardized Mortality Rate (ASMR) of LC based on the continents, world regions based on the development level and Human Development Index (HDI). ASIR and ASMR of LC expressed per 100,000 people.

Results: The highest ASIR and ASMR of LC occurred in North America (ASIR=38.3 and ASMR=28.6), more developed regions (ASIR=30.8 and ASMR=24.2), and the WPRO region of the WHO (ASIR=32.8 and ASMR=28.5), and those regions with very high HDI (ASIR=31 and ASMR=23.9). Furthermore, the lowest ASIR and ASMR of LC occurred in Africa (ASIR=5 and ASMR=4.5), the less developed regions (ASIR=20 and ASMR=18), the AFRO region (ASIR=3.9 and ASMR=3.5), and regions with low HDI (ASIR=5.4 and ASMR=4.8).

Conclusion: The highest ASIR and ASMR of LC occurred in North America, more developed regions, and the WPRO region of the WHO, and those regions with very high HDI. Most regions of the world had decreasing incidence and mortality of LC in men and increasing trend in women.

A paulada erudita d' um Leminski popular: o problema da língua na literatura brasileira pela perspectiva de dois poemas
Authors: Carvelli Keissy Guariento , Martins Ricardo André Ferreira
Published: June 2018

O artigo explora a atualização do problema da língua pela perspectiva de dois textos do poeta Paulo Leminski (1944-1989): o poema "Invernáculo" (1986) e o conto semiótico "O assassino era o escriba" (1985). Apresentam-se, inicialmente, as relações entre a formação do estado nação e das comunidades linguísticas, lançando mão dos conceitos de Pierre Bourdieu (1997) e da concepção histórica de Eric Hobsbawm (1990). Ainda, mobilizam-se os processos de gramatização da Língua Portuguesa no Brasil, tendo como foco as formulações do romancista José de Alencar, considerando as reivindicações por uma linguagem literária genuinamente brasileira. Assim, o problema da língua será apresentado em Paulo Leminski como grau máximo de atualização do tema, demonstrando pontos de contato com a tradição da ruptura, conceito caro à Literatura Brasileira.
Aproximaciones a la enseñanza del español como lengua de herencia
Authors: Fairclough Marta
Published: June 2018

El objetivo de este artículo es ofrecer una visión general de las prácticas pedagógicas actuales en la enseñanza del español como lengua heredada en Estados Unidos, incluyendo algunas de las prácticas más innovadoras del campo. Después de una breve introducción a la situación socio-demográfica y lingüística de la lengua española en dicho contexto, se describen algunas de las principales características que definen al estudiantado de lengua de herencia y se mencionan los modelos pedagógicos vigentes en los programas de herencia y su presencia en las instituciones terciarias. La segunda parte se enfoca en ciertas prácticas pedagógicas innovadoras en la enseñanza del español como lengua de herencia. Dichas innovaciones se basan en una pedagogía crítica de la lengua (Fairclough, 1995) cuyo propósito es fomentar la concientización y el pensamiento crítico por medio de la incorporación de contenido de orden sociolingüístico en el aula, la adquisición multidialectal, el translenguar, la multialfabetización cultural (New London Group, 1996) y la interacción con la comunidad. Las prácticas innovadoras conducen a forjar una conexión más estrecha entre el estudiante de lengua de herencia y la comunidad de habla, que a su vez conlleva el mantenimiento de la lengua minoritaria en una situación de contacto lingüístico.
