Critical Reflections on Teaching ESP through Constructivist, Communicative and Collaborative Technological Integrated Procedures
AbstractAccording to the constructivist approach, that considers learning an active process of construction in which the student occupies a central position, this paper is an attempt to critically reflect on the approaches of teaching English for Specific Purposes (ESP) carrying out real practices in internet and using different multimedia tools. Taking into account that the acquisition of a foreign language implies training in real contexts and social interaction, this study analyses the use of new pedagogical tendencies such as the Web 2.0. (Wikis, Blogs, Blackboard, etc.) and internet (online dictionaries, YouTube, Google search, etc.) as effective resources to carry out communicative and task-based activities for teaching ESP. This study, based on the impressions and experiences of developing constructive real tasks related to a professional subject using new technologies, reviews not only current language teaching paradigms related to social participation, but also how the technical integration of the different linguistic skills promotes communicative learning in real contexts. The findings from this exploratory study provide a better understanding on the efficiency of technology in teaching English for Specific Purposes
Determining the best set of seismicity indicators to predict earthquakes. Two case studies: Chile and the Iberian Peninsula
This work explores the use of different seismicity indicators as inputs for artificial neural networks. The combination of
multiple indicators that have already been successfully used in different seismic zones by the application of feature
selection techniques is proposed. These techniques evaluate every input and propose the best combination of them in
terms of information gain. Once these sets have been obtained, artificial neural networks are applied to four Chilean zones
(the most seismic country in the world) and to two zones of the Iberian Peninsula (a moderate seismicity area). To make
the comparison to other models possible, the prediction problem has been turned into one of classification, thus allowing
the application of other machine learning classifiers. Comparisons with original sets of inputs and different classifiers are
reported to support the degree of success achieved. Statistical tests have also been applied to confirm that the results are
significantly different than those of other classifiers. The main novelty of this work stems from the use of feature selection
techniques for improving earthquake prediction methods. So, the infor-mation gain of different seismic indicators has been
determined. Low ranked or null contribution seismic indicators have been removed, optimizing the method. The optimized
prediction method proposed has a high performance. Finally, four Chilean zones and two zones of the Iberian Peninsula
have been charac-terized by means of an information gain analysis obtained from different seismic indicators. The results
confirm the methodology proposed as the best features in terms of information gain are the same for both regions.Ministerio de Ciencia y Tecnología BIA2004-01302Ministerio de Ciencia y Tecnología TIN2011-28956-C02-01Junta de Andalucía P11-TIC-752
Speed and road accidents: behaviors, motives, and assessment of the effectiveness of penalties for speeding
When dealing with the duality of mobility and safety, speed is one of the main factors causing deaths, so this is the reason why speed is one of the most studied topics related to road safety. The main objective of this research was to identify the aspects that modulate the speed-accidents relation. Specifically, the frequency and reasons why drivers speed. On the other hand, it was also considered the perception of drivers regarding the probability of penalty, the penalties imposed, and their severity. Finally, drivers¿ opinion on the effectiveness of such penalty in order to change speeding behavior was also studied. A sample of 1,100 Spanish drivers over 14 years old and having any kind of driving license was used. The results showed that approximately the third part of drivers always or sometimes sped. Among the specific reasons, the hurry, not having noticed, that the limits are too low or that the conditions allow doing so were the most frequent. Likewise, drivers considered as limited the probability of being caught. Finally, more than half of the drivers considered that the penalty they received was appropriate. Moreover, half of the drivers that received a penalty claimed that they changed their speeding habits as a result of such penalty. Drivers who speed are completely aware of the fact that they are breaking the traffic rules. Their speeding behavior is intentional in 80% of the cases. They are not aware of the risks of speeding since they justified their behavior by saying the speed limits are too low, the conditions on the roads allow doing so, or that it was a habit
Consistency between the subjective perception of feeling indisposed, the decision to drive and driving performance
Drivers' health and fitness are essential issues in order to predict traffic crashes, taking into account that these characteristics are essential to perform this task correctly and safety. The purpose of this research was to analyze the frequency in which drivers who feel physically or emotionally unable to drive decide to perform this task, or not, under states of indisposition, as well as the perception of the effect that this indisposition had on driving. This cross-sectional study used a total sample of n=1200 (666 [56%] men and 534 [44%] women) Spanish drivers, who answered a questionnaire designed to collect data about their psychosocial characteristics, driving habits and perceptions about their driving performance and safety behaviors related with physical and mental health. The main selection criteria were to be in possession of any type of driving license for vehicles other than motorcycles and to drive frequently. The results showed that 62.5% of the participants that were not in perfect con- ditions to drive at times decided not to drive and 37.5% decided to use the vehicle. Furthermore, 16.5% of the starting sample experienced inappropriate psychophysical conditions while driving. In the group of drivers who decided to use the vehicle, 46.9% admitted that their driving was affected. It was determined that there is a substantial lack of correspondence between driver's perceptions and behaviors with respect to the impact of health conditions on crash risk, and a growing need to raise people's awareness regarding this fact. A large number of drivers continue driving even when they are not in condition to do so, which is clearly a risky behavior. It seems necessary to implement preventive actions and measures oriented to raise appropriate public awareness about the risks derived from driving under an altered physical or emotional stat
Smoking while Driving: Frequency, Motives, Perceived Risk and Punishment
When dealing with the duality of traffic accidents and road safety, smoking while driving is one of the factors that, despite the social beliefs and/or misconceptions, causes a large number of injuries and deaths worldwide. Although smoking is a well-known harmful behavior for people's health, it affects health and safety in many ways, perhaps more than some segments of the population can imagine. This is the specific case of drivers. The main objective of this study was to describe the behavioral and representational aspects of drivers that modulate the smoking-accidents relation. Specifically, it focuses in the frequency and reasons why drivers smoke while driving. On the other hand, it was also considered the perception of drivers regarding the probability of penalty, the penalties imposed, and their severity. Finally, drivers' opinion on the effectiveness of such penalty in order to change this behavior was also studied. A sample of 1100 Spanish drivers was obtained from a national sampling process. The results showed that approximately the 11% of drivers circulate regularly smoking. Among the specific reasons, the most common is that constitutes a habit of the interviewed driver. Regarding punishment, drivers considered as limited the probability of being caught. Moreover, there has been no respondents who have been fined for this behavior while driving. In general, it seems that drivers are aware of the risk implied by this behavior. However, there are very few drivers who value this as a high-risk behavior. This agrees with the respondents' opinion that it is, in other words, driving under a low sense of responsibility. This, it results logical that the sanction that the respondents believe more appropriate for the behavior of smoking while driving is an economic penalty. As a conclusion, it has been remarked that there is a clear lack of correspondence between the risk perceived in this misbehavior and the frequency and motives argued to perform it while driving. It is worth mentioning that it makes important to improve the awareness and monitoring of this behavior among Spanish drivers as a manner to, first, promote healthy habits among key sectors of population, and, second, to prevent potential road crasher related to the psychomotor impairments that this behavior implies on driving performance
Is there a predisposition towards the use of new technologies within the traffic field of emerging countries? The case of the Dominican Republic
Technological devices are becoming more and more integrated in the management and control of traffic in big cities. The population perceives the benefits provided by these systems, and, therefore, citizens usually have a favorable opinion of them. However, emerging countries, which have fewer available infrastructures, could present a certain lack of trust. The objective of this work is to detect the level of knowledge and predisposition towards the use of new technologies in the transportation field of the Dominican Republic. For this study, the National Survey on Mobility was administered to a sample of Dominican citizens, proportional to the ONE census and to sex, age and province. The knowledge of ITS topics, as well as the use of mobile applications for mobility, are scarce; however, there was a significant increase that can be observed in only one year. Moreover, technology is, in general, positively assessed for what concerns the improvement of the traffic field, even though there is a lack of predisposition to provide one's personal data, which is necessary for these devices. The process of technological development in the country must be backed up by laws that protect the citizens' privacy. Thus, technologies that can improve road safety, mobility and sustainability can be implemented in the country
Education for Road Safety: What is the State of Affairs in Three Groups of Vulnerable Road Users in Spain?
RSE (Road Safety Education) is well recognized as a reliable predictor of future safety and health outcomes. However, most countries have been slow to develop it, which has contributed to the sensitivity of the situation, as traffic accidents continue to be a major concern for community health. This paper aims to describe and compare key variables related to the RSE among three critical segments of the population, using the data provided by: 477 high school students, 843 university students and 476 older adults. Differential coverage rates were found. Perceived quality, aroused interest and attributed utility for RSE interventions were also compared among groups, finding substantial differences among them in terms of these three aspects of the intervention. Although coverage of RSE-related programs has grown considerably during the last years, substantial difficulties are still evident
Perception of the impact of certain health conditions on driving performance
Driving task requires the joint performance of many abilities which can be altered by several psychophysical conditions. Furthermore, a large number of recent studies on driving has found that there are several conditions that may affect the ability to operate safely motor vehicles and to prevent road crashes. The objective of this study was to describe the perception of drivers about the effect of certain health conditions on driving performance. This cross-sectional study used a total sample of n=1200 (666 [56%] men and 534 [44%] women) Spanish drivers, who answered a questionnaire designed to collect data about their psychosocial characteristics, driving habits and perceptions about the driving task. One-way ANOVA and Bonferroni's Post-hoc tests were performed to compare data among groups of drivers. Results showed that that drivers consider that the influence of alcohol, drugs, drowsiness and medicine consumption may impair their driving, but do not take into account certain health conditions that may be common among the population of drivers, such as diabetes, allergies, joint pains, myopia, heart or post-heart-attack problems, as well as headaches and migraines, as risk-related, regarding its potential negative impact on driving performance. In short, there is a substantial lack of correspondence between driver's perceptions and behaviors with respect to the impact of health conditions on crash risk, and a growing need to raise people's awareness regarding certain health conditions that may impair driving through road safety formation and media campaigns. Furthermore, taking into account the frequency of the health conditions analyzed and their high impact on driving, this research suggests implementing systems that fulfill two basic requirements: to improve the flow of preventive information for drivers, and strengthen the control and monitoring of their health through a joint action of the health care system and the traffic syste
Prevalence and perception of depressive symptomatology among Spanish drivers and its relation to driving safety
Depression is currently the most frequent mental disorder and one of the main causes of losing years of healthy life. This disorder entails a cognitive and motor deterioration that is seriously detrimental to driving. From the analysis of the interviewed drivers' attitudes, knowledge and behaviors, the objective of this paper was the following one: detect the impact of depressive symptoms on a driver's sample and its relationship with several variables related to driving and road safety. A sample of 1.200 Spanish drivers ranging from 18 to 64 years was used, 666 men and 534 women were asked to answer a questionnaire composed by a set of items structured in different sections. The only selection criteria were to be in possession of any type of driving license for vehicles other than motorcycles and drive frequently. 21.9% of the drivers showed signs or symptoms linked with a depressive disorder. There were found significant contingences between the presence of depressive symptoms and a lower risk-taking while driving. It is necessary to propose establishing systems that fulfil two essential requirements: on the one hand, to inform, train and make the drivers aware of detecting and managing the symptoms linked to depression; on the other hand, to detect the drivers that show cognitive and motor deterioration linked to depressive symptoms, and to promote their self-regulation, taking into account the negative implications of driving under depressive symptomatology for performance and road safety in general
