Experience-Sampling Methodology with a Mobile Device in Fibromyalgia
Castilla Diana,Botella Cristina,García-Palacios Azucena,Farfallini Luis,Miralles Ignacio
International Journal of Telemedicine and Applications , 2012, DOI: 10.1155/2012/162673
Abstract: This work describes the usability studies conducted in the development of an experience-sampling methodology (ESM) system running in a mobile device. The goal of the system is to improve the accuracy and ecology in gathering daily self-report data in individuals suffering a chronic pain condition, fibromyalgia. The usability studies showed that the developed software to conduct ESM with mobile devices (smartphones, cell phones) can be successfully used by individuals with fibromyalgia of different ages and with low level of expertise in the use of information and communication technologies. 100% of users completed the tasks successfully, although some have completely illiterate. Also there seems to be a clear difference in the way of interaction obtained in the two studies carried out. 1. Introduction Chronic pain is one of the most common causes of disability, affecting millions of people around the world. Fibromyalgia (FM) is a chronic musculoskeletal pain condition with unknown etiology, characterized by widespread pain accompanied by fatigue and disturbed sleep and mood [1]. Patients remain symptomatic and do not improve over long periods of time. There is a growing interest in the study of fibromyalgia in order to understand the mechanisms underlying this condition and to offer a better treatment response to the individuals who suffer this impairing disease. In order to achieve this goal it is important to improve the assessment of key variables like pain and fatigue intensity and mood, among others. One methodology that could be very useful in this field is experience-sampling methodology (ESM) aimed to explore the daily experience of individuals suffering different pathologies (in our case fibromyalgia). ESM is a within-day self-assessment technique in which participants are prompted at established or random intervals to report on relevant variables related to their health condition. This method presents several advantages over traditional assessment. Some authors [2–5] highlight the main advantages of ESM, including: (a) enhances ecological validity because it assesses participants in their normal daily environment; (b) minimizes retrospective bias by assessing the participant’s experience in the moment; (c) allows for an examination of the context of experiences. Ecological momentary assessment (EMA) is a repeated sampling of behaviors and experiences of the subject in real time and in real environment. EMA reduces the effects of retrospective biases and provides ecological information to a better understanding of the processes of psychiatric
Introducing Engineering Students to Historical/Cultural Perspectives through Story-Centered On-Line Learning  [PDF]
Luis A Godoy
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.22009
Abstract: Several authors argued that history of science should be an integral part of science education; however, there are many obstacles to carry out an implementation within this approach, including that lecturers normally lack a necessary historical background (a situation that is largely aggravated in engineering faculties), and the impossi- bility of including new courses or credits in an already tight curriculum. The development of on-line modules that engineering students can work outside their normal schedule of classes, introducing historical/cultural per- spectives, is presented in this paper. E-learning and knowledge management strategies are used in the context of science education at undergraduate and graduate levels. The approach is based on learning-by-doing in a virtual environment, and specifically presents story-centered activities, in which the student is faced with a problem and plays the role of an expert to provide a solution to the case. The specific case considered develops in the form of a controversy concerning the origin of the studies of column buckling. Two sets of information are available for navigation in the module: specific information that the student can explore (containing historical material di- rectly connected to the case provided), and more general information (providing the historical/cultural context to the problem). A first application has been made with civil engineering students, who had to write a two-page white paper as a consequence of their work on the problem. The interest generated in the participating students and the positive evaluation of their experience seems to indicate that this type of activity can serve to enhance traditional engineering lectures by incorporating a historical dimension. The present web-based approach could be extended to tackle similar conflicts in fields for which there is ample documentation available in the literature or in other historical episodes which may lead to rich discussions.

Processing Facilitation Strategies in OV and VO Languages: A Corpus Study  [PDF]
Luis Pastor, Itziar Laka
Open Journal of Modern Linguistics (OJML) , 2013, DOI: 10.4236/ojml.2013.33033

The present corpus study aimed to examine whether Basque (OV) resorts more often than Spanish (VO) to certain grammatical operations, in order to minimize the number of arguments to be processed before the verb. Ueno & Polinsky (2009) argue that VO/OV languages use certain grammatical resources with different frequencies in order to facilitate real-time processing. They observe that both OV and VO languages in their sample (Japanese, Turkish and Spanish) have a similar frequency of use of subject pro-drop; however, they find that OV languages (Japanese, Turkish) use more intransitive sentences than VO languages (English, Spanish), and conclude this is an OV-specific strategy to facilitate processing. We conducted a comparative corpus study of Spanish (VO) and Basque (OV). Results show (a) that the frequency of use of subject pro-drop is higher in Basque than in Spanish; and (b) Basque does not use more intransitive sentences than Spanish; both languages have a similar frequency of intransitive sentences. Based on these findings, we conclude that the frequency of use of grammatical resources to facilitate the processing does not depend on a single typological trait (VO/OV) but it is modulated by the concurrence of other grammatical features.

Past, Present and Future Climate of Antarctica  [PDF]
Alvarinho J. Luis
International Journal of Geosciences (IJG) , 2013, DOI: 10.4236/ijg.2013.46089

Anthropogenic warming of near-surface atmosphere in the last 50 years is dominant over the west Antarctic Peninsula. Ozone depletion has led to partly cooling of the stratosphere. The positive polarity of the Southern Hemisphere Annular Mode (SAM) index and its enhancement over the past 50 years have intensified the westerlies over the Southern Ocean, and induced warming of Antarctic Peninsula. Dictated by local ocean-atmosphere processes and remote forcing, the Antarctic sea ice extent is increasing, contrary to climate model predictions for the 21st century, and this increase has strong regional and seasonal signatures. Models incorporating doubling of present day CO2 predict warming of the Antarctic sea ice zone, a reduction in sea ice cover, and warming of the Antarctic Plateau, accompanied by increased snowfall.

An Extended Model of Currency Options Applicable as Policy Tool for Central Banks with Inflation Targeting and Dollarized Economies  [PDF]
Luis-Felipe Arizmendi
Theoretical Economics Letters (TEL) , 2013, DOI: 10.4236/tel.2013.33027

The purpose of this paper is to provide a new set of tools for policy makers at central banks. Based on the Garman-Kohlhagen [1] formula for currency options, this research extends it with the Taylor-rule expression used for inflation targeting, thus obtaining the corresponding Call and Put options and the first and higher-degree partial derivatives known as “Greeks” for key variables such as the policy target domestic interest rate and the output gap.

New Evidence on Rotational Dynamics  [PDF]
Luis Alberto Pérez
World Journal of Mechanics (WJM) , 2013, DOI: 10.4236/wjm.2013.33016

In this paper, the author confirmed a new theory to explain the mechanical behavior of macroscopic bodies. The confirmed hypothesis is the Theory of Dynamics Interaction by the Professor Gabriel Barceló. Barceló explained his theory in an article called “Analysis of Dynamics Fields in Noninertial Systems”, World Journal of Mechanics, Vol. 2, No. 3, 2012, pp. 175-180. This hypothesis holds that the mechanical behavior of macroscopic bodies in a non-inertial environment opens new assumptions on inertial fields and rotational dynamics. An associated experiment was presented to support the discussion in the paper. The author first became aware of the proposals of Professor Gabriel Barceló’s Theory of Dynamics Interaction through his 2006 article on Saturn planet rings, which suggested unsolved phenomena in rotational dynamics and the inception of a novel theory [1]. Intuitively, the author realized himself about the fact that the cosmos is mechanical from its smallest to its widest comprehensible appreciation. If material behavior is mechanical everywhere and every time, from a subatomic particle, wave or string, to a cluster of galaxies, then our understandable solutions must comply with the Laws of Motion, it could be believed.

The Cardiovascular Benefits of Polyphenol Compounds  [PDF]
Anthony San Luis
Advances in Anthropology (AA) , 2013, DOI: 10.4236/aa.2013.34025

In comparison, polyphenols are one of the most diverse to most other groups of bioactive phytochemicals. Polyphenols can be found in a wide range of foods that are derived from plants. Polyphenols are made up of various subgroups, but it’s the phenolics, stillbenes, and flavonoids that engender positive impacts on cardiovascular health. These three phytochemical compounds can reduce cardiovascular conditions such as hypertension and coronary heart disease. Remarkably, polyphenols and its subgroups can be found ubiquitously in most human diets. As a result, many studies have effectively illustrated the positive impacts polyphenols can induce when processed by the human body. Furthermore, research efforts have shown that modern diets and more “traditional” diets have unknowingly promoted the consumption of foods rife with polyphenols. These findings are starting to be incorporated into the public health discipline as a more practical option for more sustainable nutritional interventions. In all, polyphenols can produce a myriad of positive developments on at the micro and macro level.

Trends and Interannual Variability of Winds and Turbulent Heat Flux in the Indian Ocean Sector of Southern Ocean during 2000-2009  [PDF]
Alvarinho J. Luis
Atmospheric and Climate Sciences (ACS) , 2014, DOI: 10.4236/acs.2014.42030
Abstract: Using satellite-based wind and sea surface temperature (SST) observations, linear trend and inter-annual variability of wind stress, turbulent heat flux (Q) and wind stress curl are addressed for the Indian Ocean sector of the Southern Ocean (ISO, 0°E - 155°E) for the period 2000-2009. The analysis reveals that spatial mean of Q varies between 70 and 73 Wm-2 in the austral summer and winter, respectively, while the mean wind stress is nearly same at 0.22 Nm-2 for both seasons. The anticyclonic curl dominates the ISO, which increases from 0.15 × 10-7 to 0.35 × 10-7 Nm-3 during the austral summer. The detrended box-mean time series of Q, wind stress, and wind stress curl exhibits a decreasing trend of –6.3 ± 1.6 Wm-2·decade-1, -0.012 ± 0.004 Nm-2·decade-1 and -0.48 ± 0.6 × 10-8 Nm-3·decade-1, respectively. The Empirical Orthogonal Function (EOF) analysis was carried out to study inter-annual variability. EOF-1 of Q captures 25% of the total variance, which mimics the austral summer pattern; its time coefficient is highly and negatively correlated with a 2-month lagged Nino3.4 SST index (r =-0.8 at 95% confidence). EOF-1 of wind stress accounts for 35% of the total variance and its time coefficient is strongly correlated with the Antarctic Oscillation (r= 0.86 at 95% confidence). EOF-1 of wind stress curl captures 15% of the total variance; its time coefficient is correlated to the Nino3.4 SST index (r= 0.65 at 95% confidence) with the former lagging the latter by two years. The repercussions of the weakening trends of the climatic parameters on
