The Influence of Explicit, Implicit, and Contrastive Lexical Approaches on Pragmatic Competence: The Case of Iranian EFL Learners
Authors: Ziafar Meisam
Published: June 2018

Research literature suggests the positive role of lexical chunks and translation in teaching and learning pragmatics (Ketko, H. 2000. Importance of multi-word chunks in facilitating communicative competence and its pedagogic implications.The Language Teacher 24(12). 5–11; Rose, K. R. 1999. Teachers and students learning about requests in Hong Kong. In E. Hinkel (Ed.),Culture in second language teaching and learning, 167–180. Cambridge: Cambridge University Press.). Accordingly, the present study aimed at investigating the influence of contrastive lexical approach (CLA), in comparison with explicit and implicit approaches, on Iranian EFL learners’ pragmatic competence. Sixty-three participants were randomly assigned to three treatment groups and received dissimilar instructional treatments for ten 30-minute sessions. A pretest-posttest equivalent-groups research design was carried out and pretest scores were used as the covariate in a one-way ANCOVA data analysis. CLA showed no significant advantage over the other two methods. Previous studies have often combined a contrastive method with explicit teaching. Confounding variables in this way may have made interpretation of results problematic. In the present research explicit and contrastive instructions were kept separate and no significant difference was found between the three treatments, although all instruction types enhanced the language learners’ pragmatic competence. As a result, a pragmatic teaching course is recommended which incorporates the useful teaching techniques and practices of these three approaches to teaching pragmatic competence.
The Rise and Fall of the German IPO Market, 1870-1938
Authors: Burhop Carsten , Chambers David , Cheffins Brian
Published: June 2018

This study of over 1,000 initial public offerings (IPOs) on the Berlin stock exchange from German unification to the eve of World War II draws attention to the importance of regulation and deepens our understanding of German stock market development. An increasingly exacting regulatory environment from the early 1880s to 1914 made a vital contribution to the higher likelihood of firms going public surviving. In the inhospitable regulatory setting of the 1930s, IPO activity drew to a halt and the development in the German stock market over the preceding decades reversed. As a complement to our analysis of the impact of regulation, we document the increased involvement of leading universal banks (D-banks) in the IPO market over the whole period.

Analysis of a long-term Forest Accountancy Network to Support Management and Controlling
Authors: Dög Markus , Wildberg Johannes , Möhring Bernhard
Published: June 2018

Multifunctional forestry in Germany is characterized by long production periods and complex biological-technical processes. Private forest enterprises are complex systems which are closely interwoven with the economic environment. To ensure their economic success, forest landowners need to take the economic development into consideration and adapt their management strategies. Management accounting is an important source for information needed to fulfil main tasks of accounting that help to manage forest enterprises: ‘description’, ‘explanation’ and ‘decision making’. To get general data, long time series data, taken from Forest Accountancy Networks (FAN), can be analysed. For more than 45 years, data from the FAN Westfalen-Lippe in Germany has been collected and analysed by the department of Forest Economics and Forest Management at the University of Göttingen. The long-term development and adaptation strategies of defined groups of private forest enterprises can be illustrated using this data. These valuable time series can support decision-making processes for private forest landowners and provide tools for forest policy. The data shows that private forest enterprises, with spruce as the dominating tree species, have performed above average in terms of operating revenues and profit margins, but are also more susceptible to calamities resulting in higher involuntary timber harvests.

Published: June 2018

Foodborne illnesses have been a heavy burden in the United States and globally. Many medicinal herbs have been cultivated in the US and many of which contain antimicrobial compounds with the potential to be used for food preservation. Methanol/water extracts of pomegranate peel (“PP”, Punica Granatum L.), Chinese gallnut (“CG”, Galla chinensis), Forsythia fruit (“FF”, Forsythia suspensa) and Baikal skullcap root (“BS”, Scutellaria baicalensis) were tested for antimicrobial activity using the agar diffusion assay on tryptic soy agar (TSA) and microdilution assay in tryptic soy broth (TSB). CG and PP extracts showed good to excellent inhibitory effect against Vibrio parahaemolyticus and Listeria monocytogenes in both assays, with a minimum inhibitory concentration (MIC) range from 0.04 to 5 mg/mL. BS had moderate inhibitory effects against V. parahaemolyticus with an MIC of 5 mg/mL in TSB, and against L. monocytogenes with an MIC of 20 mg/mL on TSA. CG was analyzed using LC-MS and fractionated using HPLC. The major components were identified as gallic acid, digallic acid, methyl gallate, and gallotannins (oligo-galloyl-D-glucose, nGG, n = 1~10). Six fractions (I - VI) were collected and their antibacterial activities were tested against L. monocytogenes, and V. parahaemolyticus both on TSA and in TSB. On TSA, fraction III, IV and V inhibited V. parahaemolyticus but no fraction inhibited L. monocytogenes. In TSB, all fractions inhibited V. parahaemolyticus and fractions II - V inhibited L. monocytogenes. Future studies are needed to investigate the effects of medicinal plants on food products.
The Complexities of Metal Detecting Policy and Practice: A Response to Samuel Hardy, ‘Quantitative Analysis of Open-Source Data on Metal Detecting for Cultural Property’ (Cogent Social Sciences 3, 2017)
Authors: Deckers Pieterjan , Dobat Andres , Ferguson Natasha , Heeren Stijn , Lewis Michael , Thomas Suzie
Published: June 2018

In his paper ‘Quantitative analysis of open-source data on metal detecting for cultural property’, Samuel Hardy suggested that permissive policy is ineffective in minimizing the damage done to cultural heritage by non-professional metal detecting. This response paper contests the basic assumptions upon which this analysis is based. While Hardy‘s comparative, quantitative approach is laudable, it is founded in a biased and simplistic outlook on the metal detecting phenomenon.
Frequency independent AC electrical conductivity and dielectric properties of polyaniline-based conductive thermosetting composite
Authors: Kumar Vipin , Das Sukanta , Yokozeki Tomohiro
Published: June 2018

Electrical impedance characteristics of polyaniline (PANI)-dodecylbenzenesulfonic acid (DBSA)/divinylbenzene (DVB) composite were evaluated as a function of PANI content in the frequency range of 102–108 Hz. Polymer composites were prepared by a one-step thermal process where doping of the PANI and curing of the polymer matrix DVB have occurred simultaneously in the presence of a strong protonic acid, i.e. DBSA. The alternating current (AC) conductivity value with respect to frequency of the PANI-DBSA/DVB composite shows a direct current (DC) plateau up to an extensive frequency range. Almost metal-like behavior is obtained with such highly conductive plastic material. In all frequency regions, composites with higher PANI concentration showed a frequency independent behavior, while in the case of neat composites without PANI, a frequency dependent behavior is observed. A plot of the real part of complex impedance vs. frequency and a plot of AC conductivity of the composites indicate that the high electrical conductivity in high PANI concentration composites is because of the direct contacts between filler PANI particles. In this work, AC conductivity behavior and dielectric properties of very highly conductive thermoset composites are presented, and it is shown that conductivity is frequency independent for a very high frequency range (up to 108 Hz).

Published: June 2018

A series of magnetically recyclable NiFe2O4/ZnO nanocomposites have been successfully fabricated by a facile two-step route. The as-prepared NiFe2O4/ZnO nanocomposites were characterized by X-ray diffraction, field-emission scanning electron microscopy, vibrating sample magnetometer, ultraviolet-visible diffuse reflectance spectroscopy and photoluminescence spectroscopy. The results demonstrate that the NiFe2O4/ZnO nanocomposites are composed of ZnO particles (50–120 nm) integrated with NiFe2O4 particles (30–80 nm). Compared with bare ZnO, the NiFe2O4/ZnO nanocomposites exhibit evidently enhanced visible light absorption and decreased recombination of photo-generated electron-hole pairs. Moreover, the nanocomposites exhibit enhanced photocatalytic performance for the degradation of methylene blue under simulated solar light irradiation when compared with bare ZnO, and the 20%-NiFe2O4/ZnO nanocomposite is observed as the optimal composite. This is ascribed to the more efficient separation of photo-generated electron-hole pairs and generation of hydroxyl (˙OH) radicals in the 20%-NiFe2O4/ZnO nanocomposite. Furthermore, the NiFe2O4/ZnO nanocomposites have a high saturation magnetization, indicating that they can be magnetically separated and recycled from organic dye wastewater.
L’alitta dal γυμνάσιον alla spezieria
Authors: Zamuner Ilaria
Published: June 2018

In Italian language there are two words, alitta and alipta, derived from the same latin etymon alipta, shaped on gr. ἀλείπτης ‘who anoint’; however, the two terms have different categories and meanings: alitta (f.) ‘mixture of aromatic substances’ and alipta (m.) ‘who anoint’. The story of ‘alipta’ is traced from ancient Greece until contemporary age – through the middle ages – to clarify the passages that have determined the independent origin of the two terms in the Italian language.

Tok, S, Dal, N, Zekioğlu, A, Çatıkkaş, F, Balıkçı, İ, and Doğan, E. Autonomic cardiac activity among novice archers during baseline, shooting and recovery. J Strength Cond Res 34(9): 2627–2635, 2020—In the present study, we aimed to investigate whether heart rate variability (HRV) of novice archers may vary during baseline, shooting, and recovery periods. In addition, we aimed to explore whether HRV may have different patterns between successful and less successful archers and man and woman archers. The sample consisted of 39 (12 woman) novice archers ranging in age from 21 to 27. Baseline HRV activity was measured in the first stage of the experiment. Then, participants shot 10 arrows, from 18 m to an 80 cm diameter target, whereas their HRV was measured. Lastly, HRV recovery response was measured immediately after shooting. HRV was represented as low frequency (LF), high frequency (HF), and LF/HF ratio. When considering the entire sample, repeated measures of analysis of variance (ANOVA) indicated that only HF power differed among baseline, shooting, and recovery periods [F(2, 76) = 6.90, p = 0.002, ω2 = 0.15]. When the data partitioned, based on the median split of the shooting scores, repeated measures of ANOVA demonstrated that none of the HRV components differed in the less successful group from baseline to recovery. However, in the successful group, both LF [F(1.47, 30.98) = 4.75, p = 0.024, ω2 = 0.18] and HF [F(1.54, 32.37) = 6.61, p = 0.007, ω2 = 0.24] power significantly differed among baseline, shooting, and recovery. No differences were found between man and woman archers in terms of HRV indices. The results of the present study indicated that physical activities requiring the use of perceptual motor skills, in addition to physical qualities, may lead to different HRV responses. Moreover, coaches aiming to develop archers' shooting accuracy may take into account LF power measured during an arrow shooting session.

Takeuchi, K, Takemura, M, Nakamura, M, Tsukuda, F, and Miyakawa, S. Effects of active and passive warm-ups on range of motion, strength, and muscle passive properties in ankle plantarflexor muscles. J Strength Cond Res 35(1): 141–146, 2021—The purpose of this study was to examine the effects of active and passive warm-ups on flexibility and strength of calf muscles. Fourteen healthy males (age: 23.1 ± 2.6 years, height: 172.7 ± 5.6 cm, and body mass: 64.5 ± 7.0 kg) performed 3 types of warm-ups respectively for 10 minutes in a random order: an active warm-up by pedaling a cycling ergometer, an active warm-up doing repeated isometric contractions, and a passive warm-up in a hot water bath. To assess flexibility, range of motion (ROM) of ankle dorsiflexion, passive torque of ankle plantarflexion, and muscle tendon junction (MTJ) displacement were measured and then muscle tendon unit (MTU) stiffness was calculated. After the flexibility assessment, peak torque during maximum voluntary isometric contraction was measured to assess the isometric strength. These data were compared before and after each warm-up. As a result, all 3 types of warm-ups increased ROM (p < 0.05) and passive torque at terminal ROM (p < 0.01), but there were no significant changes in MTU stiffness or MTJ displacement. The active warm-up by pedaling a cycling ergometer increased peak torque during isometric contraction (p < 0.05), whereas the other warm-ups did not show significant alterations. In conclusion, the active warm-up with aerobic exercise increased flexibility and strength of the calf muscles.

Furr, HN, Nessler, JA, and Newcomer, SC. Characterization of heart rate responses, duration, and distances traveled in youth participating in recreational skateboarding at community skateparks. J Strength Cond Res 35(2): 542–548, 2021—Recreational skateboarding continues to gain popularity in youth within the United States and abroad. Surprisingly, there is a paucity of research regarding the cardiovascular responses of youth participating in recreational skateboarding. Therefore, the purpose of this study was to test the hypothesis that skateboarding would elicit heart rates and durations consistent with the American College of Sports Medicine (ACSM) and Center for Disease Control and Prevention (CDC) recommendations for cardiovascular fitness in youth. Seventy-one recreational skateboarders (boys: 63 and girls: 8) between the ages of 6 and 17 years participated in this study. Data were acquired at 9 skateparks in the local community. After parental consent, subjects completed a questionnaire and were instrumented with a heart rate monitor (Polar V800 GPS Sports Watch), which recorded heart rate, duration, and distance traveled. Subjects were instructed to engage in typical skateboarding activities, with the duration and intensity of activity determined by the individual. Subjects were 10.6 ± 2.9 years old and had participated in skateboarding for 3.1 ± 2.4 years. On average, subjects skateboarded 55.5 ± 28.4 minutes, at an average heart rate of 140.4 ± 16.1 b·min−1, and traveled an average distance of 2.65 ± 1.87 km. Results from this study suggest that youth participating in recreational skateboarding at community skateparks attain exercise intensities and durations that are comparable with the ACSM's and CDC's exercise recommendations for cardiovascular fitness in youth. These findings may hold implications for city planners considering the impact of community skateparks on physical activity in youth and overall public health.

Čular, D, Dhahbi, W, Kolak, I, Iacono, AD, Bešlija, T, Laffaye, G, and Padulo, J. Reliability, sensitivity, and minimal detectable change of a new specific climbing test for assessing asymmetry in reach technique. J Strength Cond Res 35(2): 527–534, 2021—The aims of this study were to establish intertrial and intersession reliability, sensitivity, and minimal detectable change of a new climbing test specifically for assessing asymmetry in reach technique (TEST). Twenty-four young climbers (16 males and 8 females) participated in this study. The protocol consisted of performing, in counterbalanced random order, 3 tests; TEST, maximum handgrip force, and squat on the bench, in 2 sessions (with 3 trials for each session). TEST performance was expressed as: TEST performance for left hand (TESTL), TEST performance for right hand (TESTR), and absolute symmetry index (ASI). For intertrial and intersession reliability assessment, TESTL and TESTR showed excellent reliability (intraclass correlation coefficients ranged: 0.96–1.00; SEM% ranged: 0.07–1.23; and coefficient of variation—CV%: 1.28–2.53). In addition, SEMs were smaller than the smallest worthwhile change (SWC) values (SWC% = 1.07 and 0.99 for TESTL and TESTR, respectively), and the minimal detectable change (MDC95) for both sides was small (<4.36 cm). An exception was ASI, which showed low absolute reliability and marginal sensitivity (SEM% = 15.13 > SWC% = 8.40 and CV% = 41.98). Pairwise test comparisons revealed no difference between sides. Considering the high reliability and the satisfactory sensitivity, TEST can be used to define individual asymmetry in the performance of the reach technique to the left or the right body side in climbers. However, interpreting data using the ASI index requires caution because it had poor absolute reliability and marginal sensitivity.

Baiget, E, Iglesias, X, and Rodríguez, FA. Validity of heart rate-based models for estimating oxygen uptake during tennis play. J Strength Cond Res 34(11): 3208–3216, 2020—This study aimed to assess the validity of an on-court tennis test (specific endurance tennis test [SET-Test]) and 2 heart rate (HR)-based methods for estimating oxygen uptake (V̇o
2) in competitive tennis players. Thirty-five male players performed a SET-Test to relate test duration (minutes) and V̇o
2. Two weeks later, 16 players performed a simulated match play set where HR and V̇o
2 (V̇o
2-PLAY, criterion value) were measured and then compared with V̇o
2 values predicted from the HR/V̇o
2 linear regression equations derived from the SET-Test (pV̇o
2-TEST) and from the one set match play (pV̇o
2-PLAY). Test duration and V̇o
2-TEST were strongly correlated (r
2 = 0.821, p < 0.001, SE
E = 5.6 ml·kg−1·min−1), indicating that SET-Test outcome is a somewhat good indicator of aerobic fitness in tennis players, likely to be useful for training purposes. pV̇o
2-PLAY and V̇o
2-PLAY (criterion value) were strongly correlated (r
2 = 0.832, p < 0.001) and SE
E was moderate (3.5 ml·kg−1·min−1 = 11.5%). pV̇o
2-TEST differed from the criterion (32.4 ± 10.7 vs. 30.8 ± 8.6 ml·kg−1·min−1, p < 0.001) and, although strongly correlated (r
2 = 0.689, p < 0.001), an overestimation occurred (mean Δ = 1.6 ml·kg−1·min−1 = 4.9%), yielding a high SE
E (4.8 ml·kg−1·min−1 = 15.6%). We conclude that (a) SET-Test performance is a valid and moderately accurate predictor of V̇o
2; and (b) the individual HR-V̇o
2 regression equation generated during tennis match play predicts V̇o
2 with greater accuracy than the regression derived from the SET-Test.

Safarimosavi, S, Mohebbi, H, and Rohani, H. High-intensity interval vs. continuous endurance training: Preventive effects on hormonal changes and physiological adaptations in prediabetes patients. J Strength Cond Res 35(3): 731–738, 2021—The aim of this study was to examine the effects of a 12-week high-intensity interval training (HIIT) intervention, or an isocaloric continuous endurance training (CET) intervention on insulin resistance indices and change in irisin and preptin in patients with prediabetes. Thirty-two prediabetic male patients (age = 38.7 ± 4; body mass index = 26.9 ± 1.4 kg·m−2; and V̇o
2peak = 2.49 ± 0.22 L·min−1) were randomly assigned into 3 training groups (N = 8). These groups were matched based on the required energy expenditure (EE) for completing each protocol: (a) HIIT (10 × 60 seconds at 90% peak oxygen uptake [V̇o
2peak], 1: 1 work to recovery at 50 W), (b) CET at an intensity equivalent to maximal fat oxidation (Fatmax) (CETFAT) (pedaling for a duration that expends an equivalent EE to an HIIT session [E ≈ HIIT]), (c) CET at an intensity equivalent to anaerobic threshold (CETAT) (E ≈ HIIT), and (d) the control group (CON): continued to perform their daily activities. After intervention, blood glucose levels were significantly (p < 0.05) lower in the HIIT group compared with CETAT group. Exercise training improved the insulin resistance index by 35, 28, and 37% in CETFAT, CETAT, and HIIT groups, respectively. Irisin concentrations in the HIIT and CETAT groups was significantly (p < 0.05) decreased compared with the pre-training values. Also, HIIT and CETFAT resulted in significant (p < 0.05) changes in preptin concentration compared with baseline. This study demonstrated that both HIIT and CETFAT protocols had similar effects on the insulin resistance index of prediabetic patients. Also, the intensity and type of exercise were effective factors in changing irisin and preptin concentrations.

Robertson, C, Lodin-Sundström, A, O'Hara, J, King, R, Wainwright, B, and Barlow, M. Effects of pre-race apneas on 400-m freestyle swimming performance. J Strength Cond Res 34(3): 828–837, 2020—This study aimed to establish whether a series of 3 apneas before a 400-m freestyle time-trial affected swimming performance when compared with and combined with a warm-up. Nine (6 males and 3 females) regional to national standard swimmers completed four 400-m freestyle time-trials in 4 randomized conditions: without warm-up or apneas (CON), warm-up only (WU), apneas only (AP), and warm-up and apneas (WUAP). Time-trial performance was significantly improved after WUAP (275.79 ± 12.88 seconds) compared with CON (278.66 ± 13.31 seconds, p = 0.035) and AP (278.64 ± 4.10 seconds, p = 0.015). However, there were no significant differences between the WU (276.01 ± 13.52 seconds, p > 0.05) and other interventions. Spleen volume compared with baseline was significantly reduced after the apneas by a maximum of ∼45% in the WUAP and by ∼20% in WU. This study showed that the combination of a warm-up with apneas could significantly improve 400-m freestyle swim performance compared with a control and apnea intervention. Further investigation into whether long-term apnea training can enhance this response is justified.
Ciudadanía y elecciones en la Nueva Granada. Las definiciones y su reglamentación, 1821 – 1853
Authors: Ospina Echeverri Martha Cecilia , Marín Suarez Juan Felipe
Published: June 2018

El proceso de consolidación de la ciudadanía en las primeras décadas de la era republicana del siglo XIX, ha implicado la tensión que se registra cuando se entrecruzan variables tan particulares como sus connotaciones civil y política, los debates en el contexto del ordenamiento jurídico y las demandas de la sociedad. El objetivo del artículo es examinar las prácticas y su reglamentación electoral en los inicios de la vida republicana de la Nueva Granada entre 1821 a 1853. De esta manera, el análisis de la participación se propone desde la Nueva Historia Política, perspectiva que además del estudio de los datos electorales y su reglamentación, busca relacionar elementos sociales para comprender la noción de ciudadanía. Así, las distintas expresiones y circunstancias son consideradas para entender la correlación entre individuo y estructura política, así como para retomar algunos aspectos de lo social, entre los que están la opinión pública, las sociabilidades y las variaciones discursivas en torno a la ciudadanía.

Published: June 2018

La investigación en salud puede producir conocimientos valiosos para orientar las intervenciones de este tipo ofrecidas a individuos y grupos humanos. No obstante, requiere de especificidades para preservar del daño a sujetos de especial protección ante la ley, tales como las poblaciones pertenecientes a etnias indígenas. Por parte de las autoridades internacionales encargadas de trazar normas éticas para proyectos de investigación, se han reconocido conductas científicas poco éticas en investigaciones que involucran a pueblos indígenas. Por esta razon, se han proclamado principios sobre bioética de aplicación internacional para estos grupos poblacionales. Este artículo presenta, analiza y discute posicionamientos del orden nacional e internacional al respecto.En suma, el respeto por la autonomía y la defensa del conocimiento propio son derechos que deben cumplirse y ser tenidos en cuenta al momento de realizar investigaciones científicas con pueblos indígenas. Además del consentimiento informado individual y comunitario, el uso del proceso de consulta previa y concertación permite obtener una adecuada contextualización respecto a las perspectivas, marcos y conceptos a partir de los cuales se realizará la investigación; así como las problemáticas, necesidades y beneficios de la investigación en estos grupos poblacionales.
Trabajo y salud: La Corte Constitucional frente a la tutela por accidentes y enfermedades laborales
Authors: Torres Tovar Mauricio , Torres Echeverry Nicolás
Published: June 2018

Objetivo Describir la forma en que la Corte Constitucional de Colombia ha interpretado el uso de la tutela en riesgos laborales. Se presenta en qué casos ha defendido el uso de la tutela y las líneas jurisprudenciales principales del tema.Método Análisis de una muestra representativa de las decisiones de la Corte Constitucional en tutelas en riesgos laborales durante el periodo 1992-2014. Se sistematizaron 58 tutelas con estadísticas descriptivas y se analizaron las principales líneas jurisprudenciales.Resultados La Corte ha asumido una posición proteccionista del trabajador. En 79,3 % de los casos revocó la decisión de primera o segunda instancia y concedió las pretensiones de la tutela. Ha sostenido que no se puede despedir a trabajadores que han sufrido un accidente o una enfermedad laboral sin permiso de la oficina del trabajo, y deben ser reincorporados y reubicados si es el caso. Además, ha sostenido que los trabajadores no deben soportar la incertidumbre sobre quién debe cubrir sus prestaciones, que deben ser otorgadas mientras estas discusiones se libran.Discusión La estructura institucional en donde las empresas promotoras de salud (EPS) atienden las enfermedades y accidentes de origen común y las administradoras de riesgos laborales (ARL) las de origen laboral, incentiva la negación de sus servicios y como efecto el uso de la tutela en este campo. A pesar de la claridad de las líneas jurisprudenciales, los mismos problemas jurídicos se siguen presentando a través de los años y los jueces de instancia siguen incumpliendo los precedentes establecidos por la Corte.

Published: June 2018

La revisión se propuso identificar en la literatura la prevalencia y factores asociados con la violencia sexual (VS) contra las mujeres adolescentes y adultas. Se revisaron estudios poblacionales, publicados entre 2011 y 2016, en inglés, portugués y español, en las bases de datos PubMed/Medline, Lilacs y SciELO. Los estudios fueron descritos y analizados, detallando sus características e informaciones sobre prevalencia y factores asociados a la VS. Entre los 3 002 artículos encontrados, de acuerdo con los criterios de inclusión, 15 estudios fueron objetos de esta revisión. La mayoría de los estudios se concentran en Asia y África, que también presentan las mayores prevalencias de VS. El grupo de edad predominante fue de 15 a 49 años. Se observó una gran variación de la prevalencia de VS entre los países. Con respecto a la VS cometida por una persona íntima, ésta varió del 1 % en Alemania al 92 % en Zimbabue. En cuanto a los factores asociados, se destacan la baja escolaridad, la juventud, las condiciones de salud mental y la salud sexual y reproductiva, así como el uso de alcohol y otras drogas. La revisión muestra la necesidad de profundizar en estudios sobre la violencia sexual, para contribuir a las políticas públicas, a detener la violencia contra las mujeres y la equidad de género.

Se trabajó con seis mujeres inmigrantes de primera generación que pertenecían al circuito migratorio de Puebla-Nueva York. Se aplicaron entrevistas a profundidad, el desarrollo de trayectorias migratorias e itinerarios terapéuticos.Finalmente, se realizaron entrevistas con familiares de las informantes principales para controlar sesgos u omisiones de información.Resultados Se identificó que la violencia estaba relacionada con la salud mental de las mujeres. Esta se presentó en diversas etapas de su vida y se presentaron en los  espacios que habitan y desarrollaban su vida cotidiana. La violencia se acentuaba por las relaciones jerárquicas en el grupo doméstico y espacio laboral. Además, las crisis económicas y arreglos familiares enmarcaban dicho proceso. Los arreglos familiares para salir adelante y dar continuidad al modelo de familia a pesar de la migración por motivos económicos, también tuvieron relación con las tensiones que se viven en sus hogares.Discusión Discutimos las condiciones de las vidas de las mujeres y su desarrollo de padecimientos mentales con respecto a otros estudios que desde la salud pública hanexplicado los problemas en salud mental y la migración por medio de conceptos como la aculturación y la asimilación.

Authors: Hai Tran Duy
Published: June 2018

Fluid flow profile is a dominate role in the performance of packed bed reactor. In small ratio of column-to-particle diameter, velocity pattern is strongly affected by voidage distribution, which depends on radial coordinate, flow rate and bed height. In this study, effects of voidage distribution to gas velocity profile in a packed bed with pellet particles was empirically investigated. Uniformity of local velocity at the top of the bed was clearly observed with decreasing of bed height and flow rate. For 400 mm of bed height, the measured velocities are a well fitting to Fahien and Stankovich model for any expected flow rate.
APPLICATION OF A TRANSIENT HEAT CONDUCTION MODEL FOR DESIGN OF UREA PRILLING TOWER
Authors: Tien Vu Dinh
Published: June 2018

Urea has highest nitrogen content up to 46.65 % in comparison with other fertilizers. Therefore, it is used widely in agriculture, forestry and additives for animal feed. Recently, Vietnam has 04 urea manufacturing plants in Bac Giang, Ninh Binh, Phu My and Ca Mau with total production estimated in 2014 to be 2,660 million Ton/year. Except for Ca Mau plant using granulator to produce urea granular, other plants are using prilling tower to produce prill urea. In a prilling tower, molten urea is sprayed form the top distributor. The droplets fall along the tower to exchange heat with countercurrent air flow for cooling and solidification. Until now, there is not any Vietnam engineering company having ability to design a prilling tower due to lack fundamental knowledge. In this paper, a transient heat conduction model was applied to determine the engineering parameters like cooling time and prilling tower high.

Authors: Xuan Minh Nguyen Truong
Published: June 2018

Silver nanowires with one-dimensional structures have attracted much research interest due to their potential applications in several areas. It is well-known that their properties strongly depend on the size and morphology of the silver nanostructures. Therefore, in our work, silver nanostructures were prepared using a polyol process and the effects of synthesis conditions on the formation and morphology of silver nanowires were investigated. The structure and morphology of the synthesized silver nanostructures were characterized using transmission electron microscopy (TEM) and X-ray powder diffraction (XRD). The results showed that the morphology of the silver nanowires can be effectively controlled via adjusting parameters of the synthesis process.

Authors: Uyen Nguyen Thai Ngoc
Published: June 2018

In this study, the bio-nanocomposite composed of chitosan and nanoclay was prepared by solution intercalation method. The membrane was subsequently fabricated by dry/wet phase separation technique. The structure of bio-nanocomposite was characterized by Fourier-transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) and scanning electron microscope (SEM). The membrane was applied to adsorb methylene blue (MB) for water treatment. The adsorption of MB was monitored through UV-Vis spectroscopy. The results showed that bionanocomposite membrane could adsorb MB up to 97.9 % in 150 min. The MB adsorption of bionanocomposite membrane was 234 times as high as the adsorption of the conventional chitosan films that is promising for environmental applications.
Determinantes das taxas de lucro e de acumulação no Brasil: os fatores estruturais da deterioração conjuntural de 2014-2015
Authors: BRUNO MIGUEL ANTONIO PINHO , CAFFE ANTONIO RICARDO DANTAS
Published: June 2018

RESUMO As tendências das taxas de lucro e de acumulação são indicadores fundamentais nas análises das crises econômicas. Essas variáveis respondem pelas trajetórias de crescimento econômico e são condicionadas pela distribuição funcional da renda. A deterioração da conjuntura macroeconômica a partir de 2014, no Brasil, tem sido frequentemente atribuída pela ortodoxia a erros inerentes à chamada “nova matriz de política econômica”. Entretanto, o exame das taxas de lucro e de acumulação, imediatamente após o impacto da crise americana em 2009, aponta para a reafirmação de fatores estruturais, característicos da economia brasileira atual, que não poderiam ser superados por medidas anticíclicas.
Tensões Residuais em Soldagem a Arco: Uma Visão Holística
Authors: Mishchenko Andrii , Scotti Américo
Published: June 2018

Resumo Encontram-se muitos exemplos na literatura onde se faz suposições relativas às tensões residuais que raramente são confirmadas na prática. Para validar esse enunciado, neste trabalho é apresentada uma visão crítica sobre o assunto através de uma revisão bibliográfica. Verificou-se uma série de resultados antagônicos quando pesquisadores tentaram, tanto experimentalmente, como por simulação, definir, quantificar, ou mesmo qualificar, o efeito separado de cada fator sobre a geração de tensões residuais. Concluiu-se que a razão para tal seria a falta de uma visão holística para estudar o assunto. Por isto, é proposto um diagrama que lista e classifica os fatores governantes na geração de tensões residuais como independentes e secundários, visando facilitar o entendimento do efeito de cada fator. Verificou-se também uma não harmonização, tanto na simbologia, como na terminologia, dos eixos e componentes das tensões residuais nas publicações. Dessa forma, se apresenta também uma proposta de simbologia e terminologia, com a intenção de facilitar a compreensão e transportabilidade de resultados. Espera-se, assim, ter este trabalho contribuído para um melhor entendimento das razões para que as suposições da literatura nem sempre sejam confirmadas na prática

ABSTRACT Objective This study investigates ultrasonography as an effective tool for localizing and measuring the depth and size of wooden foreign bodies to perform less invasive and easier surgery without the need for any additional radiological techniques. Methods Fifteen patients were operated to remove foreign bodies in the extremities in 2016. The side of the affected extremity, the material, size, and location of the foreign body and time of admission after injury were noted, along with CRP, WBC, and erythrocyte sedimentation rate; length of incision, surgery duration, and complications were evaluated. Results The mean patient age was 39.66 (range: 6 to 68). Of the total, 8 of the foreign bodies were in the plantar surfaces of the feet, 3 were in the cruris, 2 were in the palm of the hand, and 2 were in the fingers. All patients underwent ultrasound evaluation before surgery. The surgeries lasted less than 10 min in 13 (87%) of the cases and from 10 to 20 min in 2 cases. No complications were observed in any of the patients. Conclusion Delayed extraction of foreign bodies can lead to local infections. Ultrasonography can be a reliable option for diagnosing and localizing radiolucent foreign bodies such as wooden objects. Level of Evidence IV; Case series.

ABSTRACT Objective To clinically and radiologically evaluate patients who received meniscal suture using the outside-in technique, comparing magnetic resonance imaging (MRI), arthro-magnetic resonance imaging (arthro-MRI), and arthro-computed tomography (arthro-CT) to evaluate the healing of meniscal sutures. Methods We evaluated eight patients with an average follow-up of 15 months. The evaluation analyzed clinical parameters using the Lysholm and IKDC scores as well as MRI, arthro-MRI, and arthro-CT imaging. Results At the end of the follow-up period, mean Lysholm score was 89.5 and mean IKDC score was 78.6. In the MRI, signs of meniscal healing were observed in 50% of the cases. The arthro-MRI and arthro-CT showed signs of healing in 75% of cases. There was a positive correlation between arthro-MRI and arthro-CT results in all the cases studied (kappa correlation index=1). Conclusion Meniscal suture using the outside-in technique presented good or excellent results in 87.5% of our patients. The arthro-CT and arthro-MRI showed the same level of accuracy in detecting healing of the sutured region of the meniscus. Level of Evidence IV; Case series.

Abstract Synthetic polyploids are key breeding materials for watermelon. Compared with diploid watermelon, the tetraploid watermelon often exhibit wide phenotypic differences and differential gene expression. Digital gene expression (DGE) profile technique was performed in this study to present gene expression patterns in an autotetraploid and its progenitor diploid watermelon, and deferentially expressed genes (DEGs) related to the abiotic and biotic stress were also addressed. Altogether, 4,985 DEGs were obtained in the autotetraploid against its progenitor diploid, and 66.02% DEGs is up-regulated. GO analysis shows that these DEGs mainly distributed in ‘metabolic process’, ‘cell’ and ‘catalytic activity’. KEGG analysis revealed that these DEGs mainly cover ‘metabolic pathways’, ‘secondary metabolites’ and ‘ribosome’. Moreover, 134 tolerance related DEGs were identified which cover osmotic adjustment substance, protective enzymes/protein, signaling proteins and pathogenesis-related proteins. This study present the differential expression of stress related genes and global gene expression patterns at background level in autotetraploid watermelons. These new evidences could supplement the molecular theoretical basis for the better resistance after the genome doubling in the gourd family.

ABSTRACT Chile has strong interest in biomass production for the purpose of generating bioenergy to accomplish environmental standards for clean energy production. However, no yield or productivity information is available about forest crop plantations established at high-initial planting densities dedicated to energy production. The objective of the present study was to provide long-term results of short-rotation forest crops research trials, investigating first cutting cycle most promising species biomass production. Plantations of Acacia melanoxylon, Eucalyptus camaldulensis, Eucalyptus globulus, and Eucalyptus nitens were established at initial stockings of 5,000; 7,500 and 10,000 trees ha-1 on marginal sites with important nutritional and hydric limitations in the Biobío Region, Chile. After 48 months, E. camaldulensis reached the highest biomass yield at initial stocking of 7,500 trees ha-1 (22.5 Mg ha-1) on dry land granitic soils, and E. nitens reached 35.2 Mg ha-1 on sandy soils. Initial stockings and biomass yields were directly related, but strongly conditioned by mortality, where greater initial stocking concurred with greater mortality after 4 years. The collar diameter and total height growth was lower at higher stockings.
Subjetividades femininas na ópera oitocentista: notas sobre Norma, La Traviata e Carmen
Authors: Liblik Carmem Kummer
Published: June 2018

Resumo: Além da importância musical e teatral, as óperas oitocentistas representam, na cultura ocidental, uma inestimável importância narrativo-textual que proporcionou, junto com a cultura literária e artística da época, a configuração de subjetividades de gênero, especialmente aquelas relacionadas ao feminino. As análises de Norma, La Traviata e Carmen permitem avaliar as subjetividades femininas que eram representadas por suas protagonistas e como elas se relacionavam com seus desejos, afetos e pares amorosos. Partimos de uma leitura feminista e de gênero que tem por objetivo estudar as múltiplas possibilidades que o feminino foi representado nesta arte, vinculando-o com as principais agências que se tornaram responsáveis pela produção das subjetividades das mulheres do século XIX e que se estendem até os dias atuais: sexualidade, amor, filhos e matrimônio.
