Un periódico anarquista olvidado: "El Obrero de Ferrocarriles y Tranvías" (1902-1904)
Authors: González Jurado Deborah
Published: August 2019

El movimiento obrero en España entre los empleados del ferrocarril fue sofocado, dirigido y reconducido por la patronal desde sus orígenes. Hasta comienzos del siglo XX no encontramos ninguna publicación periódica exponente de las reivindicaciones de los empleados de este sector. En 1902 apareció El Obrero de Ferrocarriles y Tranvías, una fuente olvidada hasta hoy día por los investigadores del anarquismo que, sin embargo, por su riqueza discursiva y el alto nivel de sus colaboradores merece ser traída a la luz.
Peligro en el aire: cobertura mediática del diario "Granma" sobre accidentes aéreos en Cuba
Authors: Muñiz Zúñiga Viviana
Published: August 2019

Desde el año 1960 Cuba ha vivido cerca de una decena de accidentes aéreos con un número considerable de víctimas. Este tipo de acontecimientos, considerados por la teoría de la agenda setting como events, acarrean consecuencias materiales y psicológicas, ante las cuales es preciso tomar actitudes inmediatas. Este estudio examina la cobertura mediática realizada por el diario cubano Granma a 4 accidentes aéreos que han sucedido en los últimos 28 años en el país. Al ser el primero en analizar la influencia de este tipo de events en un medio nacional cubano, brinda un esquema de funcionamiento del hecho a partir de la evaluación cuantitativa y cualitativa de la cobertura periodística realizada en cada caso.
Periodismo e interés público. Un análisis de la pluralidad y equilibrio de las fuentes en la producción noticiosa de la Agencia Câmara Notícias
Authors: Patrício Edgard , Viana Nogueira Leidyanne
Published: August 2019

En una realidad de extremismos, el acceso a la información es esencial para la deliberación. En ese contexto, se destaca la relación entre periodismo y democracia (McQuail, 2012). Para que se concretice esa relación, el interés público debe ser un principio de la producción periodística (Kovach y Rosenstiel, 2004). Rothberg (2011) y Serrano (2011) apuestan por la pluralidad y el equilibrio de las fuentes como factores del interés público en el periodismo. Este artículo analiza el contenido de interés público en la producción de la Agencia Câmara Notícias, vehículo de comunicación de la Cámara de Diputados, en Brasil. Los datos indican que la realización del interés público por medio de la pluralidad de fuentes difícilmente ocurre en al menos el 75,5% de las noticias y que las fuentes ligadas a la coalición de partidos en el poder aparecen cuatro veces más que las referentes a los partidos de oposición.
Empoderamiento y discurso femenino: el caso de la Reina Letizia de España
Authors: Peña Jiménez Palma
Published: August 2019

El feminismo ha cobrado en los últimos años una fuerza inusitada y el colectivo de mujeres ha obtenido logros evidentes. La Reina Letizia no ha sido ajena a esta realidad, aludiendo en sus intervenciones públicas a la lucha por la igualdad, contra el acoso sexual y la violencia doméstica. Este hecho resulta relevante porque no es usual que una Reina asuma en sus discursos tal nivel de concreción y compromiso. Sobre el contenido de los mensajes de doña Letizia, y sobre el mismo hecho de su emisión, versa este trabajo. Estudiamos además el grado de implicación que adquiere con sus palabras, con especial detenimiento en los temas relacionados con la mujer.

Encuadres informativos sobre drogas en prensa uruguaya 2004-2014. Un análisis longitudinal
Authors: Zaragoza Rodrigo , Elgueta Ruiz Álvaro
Published: August 2019

Se presentan los resultados de un estudio que analiza el contenido de informaciones sobre drogas publicadas por el diario El País de Uruguay entre 2004 y 2014, en un contexto político cambiante y con un proceso de regulación del cannabis por parte del gobierno, entre medio. A través de la teoría del framing se identifican los encuadres dominantes presentes en las publicaciones. Se comprobó que, en general, el medio estudiado difunde una imagen negativa de las drogas, dominando en sus publicaciones el género informativo, con textos de poca profundidad y de carácter marcadamente sensacionalista, siendo la policía, jueces, fiscales y políticos las fuentes dominantes, mayormente ligados a temas de tráfico y delito; invisibilizando o minimizando otras voces o posturas vinculadas a la ciencia, la salud o los derechos ciudadanos.

This study aimed to evaluate in microcosm condition, the survival of Aeromonas hydrophila and Enteropathogenic Escherichia coli (EPEC), in the presence of M. oleifera aqueous seeds extract at concentrations varying from 1 to 40 g/L, and under 4 °C and 23 °C incubation temperature. It has been noted that cell abundances decrease gradually with the increasing in the seeds extract concentration. However, a marked cells regrowth was sometimes noted. In monospecies cell incubation condition, under 4 °C, the EPEC cells inhibition percentages (CIP) values varied from 52.12 to 99.84%. Those of A. hydrophila varied from 13.2 to 96%. The lowest CIPs were noted at the extract concentration 1g/L for EPEC and A. hydrophila. The highest CIP value was registered at 10 and 40 g/L for EPEC and at 15 g/L for A. hydrophila. Under 23 °C incubation, the EPEC CIPs values varied from 74.04 to 99.9% and those of A. hydrophila varied from 21.2 to 97.8%. For E. coli, the lowest and the highest CIP were recorded at the extract concentration 1g/L and 30 g/L, respectively. In bispecies cells incubation condition, the CIPs were relatively different. These results show the potential exploitation of M. oleifera extracts in the microbiological treatment of potable water.

This aim of this research is to explore and analyze to what extent the strategies to which physical education didacticsin Tunisia contributed to address the duplication of gender stereotypes. A typical approach with binary choiceregression was applied to analyze data obtained from questionnaires completed by 1326 adolescent students (724girls and 602 boys) from Tunisia. Results relieved that sport opportunities are limited by the separate expectations ofmales and females in physical education and sport settings. The analysis reveals that gender stereotypes affect girls'sports activities and that is particularly true for sports suitable for boys. The effect of the appropriated stereotype wassignificantly higher for sports practices perceived as masculine. The research ends with imminent based on thedistinction between gender skills and gender interest and implications for sport activities in order to enhanceparticipation, enjoyment, and wellbeing of people in physical education and sport activities. Hence, the need todevelop an internal logic of practice of sports activities by repeating individual and sexual differences.

Published: August 2019

The irrigation technology for smallholder agriculture is an important instrument to increasing both productivity and income. However for the incorporation of this technology to succeed into small properties, there is a need for interlocution among the different spheres of coordination of these economic agents. In this way, the main objective of this work was to analyze the participation of the institutional and organizational environments of the district of Salto do Lontra, located in the southwestern region of Parana state, in both the dissemination and strengthening of irrigation. This region has the highest concentration of smallholders in the state, hence its relevance. A detailed analysis of the organizational environment was made, in which interviews to the representatives of the organizations werw inserted in the management process of this sector. In order to identify the efficiency of organizations and the accessibility of public credit policies, questionnaires were applied to 35 irrigating smallholders, considering local customs, values and skills. The results demonstrated that the credit policy obtained by the public authority corroborates for the permanence of this economic and social agent in the field. However, organizations work individually, without synchronizing the needs of the category. On the other hand highlighting the universities, which proved to be strong disseminators of irrigation technology locally.

The objective of this study was to select mathematical equations that best fit the estimation of the leaf area of pink pepper (Schinus terebinthifolius Raddi) from the linear leaflet dimensions. 500 leaflets with different physiological ages of a commercial plantation were collected, located in the region of Gameleira, municipality of São Mateus, North of the State of Espírito Santo, Brazil. Was measured the length (L) along the main midrib, the largest width (W) and the observed leaf area (OLA) of each sheet. The product of the multiplication between L and W of the leaflets (LW) was determined. For the modeling the measurements of 400 leaflets were used, where OLA was used in function of L, W or LW. Based on the models found, we obtained the estimated leaf area (ELA). A simple linear regression was fitted for each proposed model of OLA in function of ELA. We tested the hypotheses H0: β0 = 0 versus Ha: β0 ≠ 0 and H0: β1 = 1 versus Ha: β1 ≠ 1, using Student’s t test at 5% probability. The mean values of ELA and OLA were compared by Student’s t test 5% probability. It was determined the mean error (E), mean absolute error (MAE), root mean square error (RMSE) and Willmott d index. The best adjusted equation was chosen by linear coefficient (β0) not different from zero, angular coefficient (β1) not unlike one, non-significant values of ELA and OLA, E, EAM and RQME closer to zero and Willmott’s index d closer to one. In this way, the leaf area of leaflets of Schinus terebinthifolius Raddi can be estimated by the quadratic model equation ELA = -2.6646 + 2.2124W + 1.3953(W)2 , using only the width of the leaves as a measure.

Published: August 2019

The optimum plot size for ‘Gigante’ cactus pear can be estimated by several methods; thus, ultimately aiming for efficiency, simple use and high precision, the objective of this study was to compare methods for estimating plot sizes: modified maximum curvature method, Hatheway’s convenient plot size method, linear and quadratic response plateau models, and comparison of variances method for evaluating phenotypic characteristics in experiments with ‘Gigante’ cactus pear. Plot sizes were estimated by conducting a uniformity trial. Estimated optimum plot sizes varied with the method and vegetative characteristic. The quadratic response plateau regression estimated the largest plot sizes, whereas Hatheway’s method estimated the smallest plot sizes. Comparison of variances method estimated intermediate plot sizes in comparison with the other methods for most measured characteristics. Plots sizes estimated by modified maximum curvature method are more consistent with results reported by studies on ‘Gigante’ cactus pear. 10 basic unit plot sizes estimated by the linear response plateau model can be used with high precision and practical feasibility for growing cactus pear, thereby improving the use of resources.

Authors: Du Zhumei , Risu Na , Gentu Ge , Jia Yushan , Cai Yimin
Published: August 2019

Objective: To improve the utility of native grass resources as feed in China, we investigated the dynamics of protein and carbohydrate fractions among Inner Mongolian native grasses, during ensiling and the aerobic stage, using the Cornell Net Carbohydrate and Protein System.Methods: Silages were prepared without or with lactic acid bacteria (LAB) inoculant. We analyzed the protein and carbohydrate fractions and fermentation quality of silages at 0, 5, 15, 20, 30, and 60 d of ensiling, and the stability at 0.5, 2, 5, and 10 d during the aerobic stage.Results: Inner Mongolian native grass contained 10.8% crude protein (CP) and 3.6% water-soluble carbohydrates (WSC) on a dry matter basis. During ensiling, pH and CP and WSC content decreased (p<0.05), whereas lactic acid and ammonia nitrogen (N) content increased (p<0.05). Non-protein N (PA) content increased significantly, whereas rapidly degraded true protein (PB1), intermediately degraded true protein (PB2), total carbohydrate (CHO), sugars (CA), starch (CB1), and degradable cell wall carbohydrate (CB2) content decreased during ensiling (p<0.05). At 30 d of ensiling, control and LAB-treated silages were well preserved and had lower pH (<4.2) and ammonia-N content (<0.4 g/kg of fresh matter [FM]) and higher lactic acid content (>1.0% of FM). During the aerobic stage, CP, extract ether, WSC, lactic acid, acetic acid, PB1, PB2, true protein degraded slowly (PB3), CHO, CA, CB1, and CB2 content decreased significantly in all silages, whereas pH, ammonia-N, PA, and bound true protein (PC) content increased significantly.Conclusion: Control and LAB-treated silages produced similar results in terms of fermentation quality, aerobic stability, and protein and carbohydrate fractions. Inner Mongolian native grass produced good silage, nutrients were preserved during ensiling and protein and carbohydrate losses largely occurred during the aerobic stage.

Objective: Although the slaughter of cull sows (CS) for human consumption and meat products processing appears quite common throughout the world, relatively limited scientific information regarding the meat quality parameters of this pork type is available. The present study aimed at providing the technological quality characteristics and eating quality of CS meat, and comparing with those of commercial pork.Methods: Longissimus thoracis et lumborum muscle samples of CS and finisher pigs (FP) at 24 h postmortem were collected and used for investigation of the meat quality traits (pH, color, shear force, cooking loss, water holding capacity), fatty acids, flavor compounds and sensory characteristics.Results: The CS meat had significantly higher moisture content (p = 0.0312) and water holding capacity (p = 0.0213) together with lower cooking loss (p = 0.0366) compared to the FP meat. The CS meat also exhibited higher (p = 0.0409) contents of unsaturated fatty acids, especially polyunsaturated fatty acids (PUFA, p = 0.0213) and more desirable PUFA/total saturated fatty acids ratio (p = 0.0438) compared to the FP meat. A total of 56 flavor compounds were identified, amongst the amount of 16 compounds differed significantly between the two pork groups. Most of the PUFA-derived flavor compounds (e.g., hexanal, benzaldehyde, and hydrocarbons) showed higher amounts in the CS meat. While, 3-(methylthio)-propanal and 4-methylthiazole associated with pleasant aromas (meaty and roast odor notes) were only found in the FP meat. Furthermore, no differences were reported by panelists for flavor, juiciness, tenderness, and acceptability scores between the two pork groups studied.Conclusion: The sow meat exhibited better technological quality and its eating quality could be comparable to the commercial pork. This study provides meat processors and traders with valuably scientific information which may help to improve the utilization and consumption level of sow meat.

Published: August 2019

Objective: Pellet durability, particle size distribution, growth response, tibia bone characteristics and energy retention were measured to evaluate cassava as an alternative energy source to replace maize in broiler diets with or without Ronozyme (A+VP) enzyme composites.Methods: A total of 480 one-day broiler chicks were randomly assigned to 8 treatments in a 4×2 factorial arrangement. Four levels of cassava: (0%, 25%, 50%, 75%) and 2 levels of enzymes (0 and 500 g/tonne) were used. Each treatment was replicated six times, with ten birds per replicate.Results: The particle size distribution in the diets showed an increasing trend of small particles with increase in cassava level. Pellet durability decreased (p<0.05) with cassava inclusion. Feed intake was highest in birds fed diets with medium cassava level at 1 to 24 d and 1 to 35 d of age. The body weight gain of birds reduced (p<0.037) as cassava level increased, but it increased (p<0.017 when enzymes were added. The feed conversion ratio was high (p<0.05) when cassava level was increased, but it reduced (p<0.05) when enzymes were added. The dressing percentage (DP), and weight of drumsticks reduced (p<0.05) with increasing cassava level. Enzyme supplementation increased (p<0.05) DP, and weight of breast, thighs and drumsticks. Ash content, weight, length, width, and bone strength decreased (p<0.05) when cassava level was increased, however, they were increased with enzyme addition. The contents of Ca, K, and Zn were raised (p<0.001) with increasing cassava level. Enzyme inclusion increased (p<0.001) all mineral contents in tibia bones. Body fat and energy retained as fat decreased (p<0.001) as cassava level increased. Enzyme inclusion increased (p<0.05) body protein content and energy retained as protein.Conclusion: Although broiler performance was depressed by high levels of cassava inclusion, it was not affected by low levels, which further improved by enzyme supplementation.

Objective: We investigated the temporal expression profiles of long noncoding RNA (lncRNA) and mRNA in the peripheral blood of pigs during development and identified the lncRNAs that are related to the blood-based immune system.Methods: Peripheral blood samples were obtained from the pigs at 0, 7, 28, and 180 days and 2 years of age. RNA sequencing was performed to survey the lncRNA and mRNA transcriptomes in the samples. Short time-series expression miner (STEM) was used to show temporal expression patterns in the mRNAs and lncRNAs. Gene ontology and Kyoto encyclopedia of genes and genomes analyses were performed to assess the genes’ biological relevance. To predict the functions of the identified lncRNAs, we extracted mRNAs that were nearby loci and highly correlated with the lncRNAs.Results: In total of 5,946 lncRNA and 12,354 mRNA transcripts were identified among the samples. STEM showed that most lncRNAs and mRNAs had similar temporal expression patterns during development, indicating the expressional correlation and functional relatedness between them. The five stages were divided into two classes: the suckling period and the late developmental stage. Most genes were expressed at low level during the suckling period, but at higher level during the late stages. Expression of several T-cell-related genes increased continuously during the suckling period, indicating that these genes are crucial for establishing the adaptive immune system in piglets at this stage. Notably, lncRNA TCONS-00086451may promote blood-based immune system development by upregulating nuclear factor of activated T-cells cytoplasmic 2 expression.Conclusion: This study provides a catalog of porcine peripheral blood-related lncRNAs and mRNAs and reveals the characteristics and temporal expression profiles of these lncRNAs and mRNAs during peripheral blood development from the newborn to adult stages in pigs.
Regime Switch and Effect on Per Capita Food Security Issues in South Africa
Authors: Yiseyon Hosu Sunday , Qamata Lubabalo
Published: August 2019

This paper examines whether the food security situation in South Africa is sensitive to the past and present governance systems. The study was aimed at reviewing the performance of key indicators: per capita land utilization, price index and consumption of a major staple food commodity (maize) in the pre- and post-apartheid periods. It also aimed at validating the application of population growth and food advocacy theories on South African food security. Time series analysis involving variables such as per capital land cultivation, consumption/tons and price/tons of maize within the period of 1970 to 2010 was conducted. Threshold autoregressive model (TAR) approach was used to capture per capita food security status of South Africans and to monitor trends under apartheid and post-apartheid eras. We found that there is a declining trend in per capita land cultivation and mixed results of per capita consumption of maize. The study revealed that population growth in South Africa has not been harnessed and there is possibility of worsening food security in the country. The long-run effect between the variables was established. The study recommends per capita targeting policy strategies for the improvement of staple food production and dietary balancing to ensure sustainable food security.
What Does It Mean to Move for Black Lives?
Authors: Harris Kimberly Ann ,   DePaul University
Published: August 2019

I argue that the key ideas of the movement for Black lives have resonances with Frantz Fanon’s ideas particularly in Black Skin, White Masks. I first demonstrate how the mission to repudiate Black demise and affirm Black humanity captures Fanon’s critique of universal humanism. The fear of the Black body was central to the testimonies of Darren Wilson, Jeronimo Yanez, and George Zimmerman (the individuals that shot and killed Mike Brown, Philando Castile, and Trayvon Martin respectively). Fanon prioritized the role of the body in his account of racism. It is difficult to not see the relevance of Fanon’s analysis when one considers these testimonies. Lastly, I demonstrate how the chants “Black lives matter,” “Hands up, don’t shoot,” and “I can’t breathe” are acknowledgments of the significance of Black lives and serve as contemporary instances of Fanon’s sociodiagnostic approach.
Classification of Strategies for Dealing with Student Relativism and the Epistemic Conceptual Change Strategy
Authors: Pfister Jonas ,   Philosophy Documentation Center
Published: August 2019

Student relativism is a widespread phenomenon in introductory philosophy courses. It is a pressing issue for teachers because it seems to undermine the very purpose of philosophy. Since the 1980s there is a debate about how to understand and how to deal with student relativism. However, there is as yet no comprehensive presentation of the debate. The first aim of the article is to offer a classification of the strategies for dealing with student relativism and a presentation and short assessment of the main strategies from the debate. The second aim is to present a new strategy based on the theory of conceptual change and drawing on the results from empirical research in developmental psychology on epistemic cognition. I call it the epistemic conceptual change strategy.

Commercial biotechnology in Germany: An overview
Authors: Bialojan Siegfried , SchÃ¼ler Julia
Published: August 2019

The title of Ernst & Young's 2003 Biotechnology Report, 'At the Crossroad', describes the present situation of the German biotechnology industry. This paper discusses and analyses the major findings of the Report. Major drivers in the current development include external factors such as the general economic downturn, the closed capital markets and the resulting consequences with respect to the financing situation. In addition, the pharmaceutical industry â€“ the major client for the emerging biotechnology companies â€“ erects higher hurdles by refocusing on later stage products with blockbuster potential. These factors are mostly identical in all regions of the globe. However, they hit the biotechnology industry in Germany relatively harder as it is still relatively young and therefore more vulnerable.In fact, the maturation process of the German biotechnology industry has been abruptly stopped. Unfortunately, this takes place at a time when the dynamic development during the past five years has not yet created a substantial number of stable and mature companies. Critical mass has become a major issue.

Authors: Korchemnyj Petr A.
Published: August 2019

The research paper establishes that the efficient resolution of a situation of uncertainty is achieved due to the motivational mechanisms for the manifestation of professional competencies. The psychological essence of the condition of uncertainty, the role of needs, intentions and professional goals in the restructuring of energy in the mental apparatus of a person, the place of motive as a conscious impetus of a person to specific actions are revealed. The author proposed the concept of the relationship of psycho-physiological and motivational mechanisms for the actualization of professional competencies in a situation of unexpected changes in the professional goals and objectives of the activity. The topicality of the work is due to the need to study the effect of motivation to act on the manifestation of professional competencies in a situation of uncertainty. An important goal of the research paper is assessed - a theoretical-psychological analysis of the motivational mechanisms for the expression of professional competencies of a subject of activity internally motivated for success in an unexpected professional situation, taking into account his personal, professional skills. The theoretical significance of our work is in the theoretical-methodological substantiation of the motivational model for the manifestation of the abilities of an extreme profession specialist's personality to apply professional competence in the conditions of uncertainty. It has been proved that the motivational factor of actualization of professional competencies in a situation of risk is fundamental in deciding to cope with unforeseen difficulties.

The Relationship between Teaching Skills, Academic Emotion, Academic Stress and Mindset in University Student Academic Achievement Prediction: A PLS-SEM Approach
Authors: Nazari Nabi , Far Davod Mirzaei
Published: August 2019

This cross-sectional study conducted to develop a model for predicting academic achievement of university students by investigating the relationship between teaching skills, academic emotions (positive and negative), and academic stress associated with Mindset (growth and fixed) using structural equation modeling. The statistical population consisted of 360 students of the Islamic Azad University of Hamedan who were selected randomly using a relative stratified method. The study was descriptive and correlational. The data were analyzed by SPSS version 25 and SmartPLS version 3.2.8. First, the validity of the model was estimated using Cronbach's alpha, composite reliability, convergent validity, and divergent validity; then, the coefficient of determination, effect size, and Stone-Geisser criterion were calculated for evaluating the structural model. The results showed that the validity and adequacy of the suggested model were suitable. Thus, it could be used in different situations by experts in related areas. The relationship between growth Mindset and academic achievement was significant; growth Mindset moderated the effect of negative emotion and stress on academic achievement the crucial role of professor skills in the academic achievement of students was confirmed directly or through its effect on positive emotion. The effect of teaching skills was not significant on the academic achievement of students with fixed Mindset, while the effect of academic stress confirmed on these students. Therefore, the identification of students with fixed Mindset and psychological interventions for these students can be useful in their academic achievement and their mental health.

It is still unclear how humans control mediolateral (ML) stability in walking and even more so for running. Here, foot placement strategy as a main mechanism to control ML stability was compared between walking and running. Moreover, to verify the role of foot placement as a means to control ML stability in both modes of locomotion, this study investigated the effect of external lateral stabilization on foot placement control. Ten young adults participated in this study. Kinematic data of the trunk (T6) and feet (heels) were recorded during walking and running on a treadmill in normal and stabilized conditions. Correlation between ML trunk CoM state and subsequent ML foot placement, step width, and step width variability were assessed. Paired t-tests (either SPM1d or normal) were used to compare aforementioned parameters between normal walking and running. Two-way repeated measures ANOVAs (either SPM1d or normal) were used to test for effects of walking vs. running and of normal vs. stabilized condition. We found a stronger correlation between ML trunk CoM state and ML foot placement and significantly higher step width and step width variability in walking than in running. The correlation between ML trunk CoM state and ML foot placement, step width, and step width variability were significantly decreased by external lateral stabilization in walking and running, and this reduction was stronger in walking than in running. We conclude that ML foot placement is coordinated to ML trunk CoM state to stabilize both walking and running and this coordination is stronger in walking than in running.

Licensing of eukaryotic origins of replication requires DNA loading of two copies of the Mcm2-7 replicative helicase to form a head-to-head double-hexamer, ensuring activated helicases depart the origin bidirectionally. To understand the formation and importance of this double-hexamer, we identified mutations in a conserved and essential Mcm4 motif that permit loading of two Mcm2-7 complexes but are defective for double-hexamer formation. Single-molecule studies show mutant Mcm2-7 forms initial hexamer-hexamer interactions; however, the resulting complex is unstable. Kinetic analyses of wild-type and mutant Mcm2-7 reveal a limited time window for double-hexamer formation following second Mcm2-7 association, suggesting that this process is facilitated. Double-hexamer formation is required for extensive origin DNA unwinding but not initial DNA melting or recruitment of helicase-activation proteins (Cdc45, GINS, Mcm10). Our findings elucidate dynamic mechanisms of origin licensing, and identify the transition between initial DNA melting and extensive unwinding as the first initiation event requiring double-hexamer formation.

Background

Road traffic accidents are one of the serious disasters that cause public injury, fatality and great economic loss. They are a growing public health problem around the world.

Objectives

The aim of this study was to determine epidemiological characteristics, tendency and possible influencing factors of road traffic injuries (RTIs) in China, so as to give target suggestions on preventative measures.

Methods

Road traffic accident data were obtained from National Bureau of Statistics of China and Ministry of Transport of the People’s Republic of China. Descriptive statistic such as RTIs frequency, trends of different accident types from 2007 to 2016; the RTIs difference between different regions and road surfaces were compared; and the possible influencing factors of RTIs were also explored.

Results

Over the past decade, with the mileage of constructed highway increased, the frequency of road traffic accidents have declined substantially in China, and the death toll from road traffic accidents with motor vehicles has declined from 2007 to 2015, Conversely, the number of deaths from non-motor vehicle accidents has risen rapidly since 2012. Our study showed that the traffic accident related mortality in Guizhou province was different from the level of the whole nation, and the Eastern, Central and Western areas of China were all significantly different (P < 0.001). Linear regression suggested a significant affected of gross domestic product (GDP)-per-capita, education level, the number of health institutions, populations, and car ownership status on traffic accident death tolls (P < 0.001). Moreover, cement concrete pavement roads were associated with the highest occurrence rates of RTI, and RTIs was statistically significant (P < 0.001) on different road surfaces.

Conclusion

Even though the frequency of road traffic accidents has declined, RTIs remain an urgent public health problem in China. Thus, the government should give some target preventative measures to reduce RTIs, aiming at different regions, the increasing trend of the death toll related to non-motor vehicles and the highest occurrence on cement concrete pavement roads.

Este artigo analisa o processo de institucionalização – habitualização, objetivação e sedi-mentação (Berger e Luckmann, 1966) – das Estruturas Formais de Investigação em Tu-rismo/EFIT no Brasil, através da teoria institucional, em sua perspectiva histórica. Esta pes-quisa, descritiva e explicativa, é do tipo censo. Empiricamente, recorreu-se a apreensão de dados secundários, de todos os 234 grupos de pesquisa formalmente registrados desde 1964 e ativos em 2016 no diretório de grupos do CNPq, eleitos como o tipo mais represen-tativo de EFIT na pesquisa anterior (Pimentel, 2016a). Os dados foram tratados quantitati-vamente por meio do software SPSS e qualitativamente pela técnica de análise de conteúdo. Foram identificadas 3 etapas marcantes no processo de institucionalização das EFIT no Bra-sil: na primeira fase (1964-2001) de Habitualização, criaram-se cursos superiores para a formação em turismo, expandiu-se o tema “turismo” no ambiente acadêmico e observou-se sua inserção como linha de pesquisa. Na segunda fase, da Objetivação (2002-2009), o tema consolidou-se via criação de grupos específicos de pesquisa, em grande quantidade. Na terceira fase (2010-atual), sedimentam-se as EFIT, observa-se o contingente de egressos de graduações em turismo, com mestrado e doutorado, inseridos em IES como professores-pesquisadores e começa a formar-se novas gerações de pesquisadores. Todavia, uma plena institucionalização requer a transmissão intergeracional de estruturas objetivas e referen-cias simbólicas de geração de conhecimento.

Published: August 2019

Purpose: The current study aimed to assess the diet quality of urban and rural pregnant women in a south-western district (Jashore) in Bangladesh.

Methodology: It was a cross-sectional study which was conducted among pregnant women (Sample size, N= 154). The respondents were selected from urban and rural areas of Jashore district. Data was collected through a pre-tested questionnaire comprising of socio-demographic and economic data, data on different food groups consumption. The data concerning food consumption was used to assess the diet quality of the respondents. For statistical analysis, IBM SPSS Statistics version 21.0 was used in the study.

Results: Among all the respondents, mean Dietary Diversity Score (DDS) was 5.40±0.96. It was also seen that minimum DDS was 3.0 and maximum DDS was 7.0 among all the pregnant women. A significant difference was observed between the mean DDS of urban and rural pregnant women (P < .05). The mean DDS of urban pregnant women was 6.46±0.19 and mean DDS of rural

pregnant women was 4.61±0.56. Moreover, about 62% of urban respondents’ diet quality was of high level, 27% of urban respondents’ diet was of medium-quality and about 11% of urban respondents were found to have low diet quality. On the other hand, only 18% of rural respondents had high diet quality, 57% had a medium-quality diet and about 25% of rural pregnant women were found to have a low diet quality. 

Conclusion: It can be concluded from the study that the majority of the urban pregnant women of the study area had a higher quality diet than their rural counterparts.

Background: Hepatitis B virus (HBV) infection is endemic and well documented in different locations of Nigeria among different sub-groups. Information regarding the prevalence of HBV in HIV infected women is scarce especially in Abuja, the capital city of Nigeria.

Aim: This study aimed at determining the prevalence of Hepatitis B surface antigen (HBsAg) among HIV infected women seeking for antiretroviral therapy (ART) at the National Institute for Pharmaceutical Research and Development (NIPRD), Abuja, Nigeria.

Materials and Methods: A health facility-based cross-sectional study was carried out in our laboratory from May, 2017 to March, 2019 among 1,386 recruited HIV infected women that were screened for HBsAg. Positive samples were confirmed using ELISA. Their socio-demographic data were collected using a questionnaire and written informed consent was obtained prior to study. Data were analyzed using frequency distribution table and SPSS (version 20.0).

Results: Out of the 1,386 HIV infected women tested, 114 were seropositive for HBV infection giving an infection prevalence of 8.2%. The highest prevalence (2.2%) was observed at age group 25 – 29 years and followed by (1.7%) at age groups of 20 – 24 and 35 – 39 years.

Conclusion: This finding confirms high endemic of HBV infection. We recommend that HIV infected women should be routinely screened for HBV as part of ART commencement requirement.
