El concepto de salud: Una explicación sobre su unicidad, multiplicidad y los modelos de salud. The concept of health: An explanation of its uniqueness, multiplicity and health models

It is showed a health perspective with multiple meanings and the need to use multiple models. From the ancient concept of negative health, which continues in full force, to models of positive health, there is a long road full of theoretical approaches and models, among which are the biopsychosocial model, the salutogenic model, the positive health model from positive psychology, the holistic model, the model of personal choice, the model of health as welfare, the model of health as maturity, the model of emotional intelligence as health, and the health model of resilience as health, among others. The use of these models, in a proper manner, enhances the professional work and makes more efficient use of health resources.
Understanding medical students’ views of chronic fatigue syndrome: A qualitative study

Chronic fatigue syndrome receives little attention in the medical curriculum. This study explores UK medical students’ knowledge of and attitudes towards chronic fatigue syndrome. Semi-structured interviews (average length 22 minutes) were conducted with 21 participants (7 females and 14 males) in years 3 (n = 4), 4 (n = 11) and 5 (n = 6) of their studies. Inductive thematic analysis taking a realist perspective produced three themes: limited knowledge, influences on attitudes and training needs. Students acquired their knowledge and attitudes largely from informal sources and expressed difficulty understanding chronic fatigue syndrome within a traditional biomedical framework. Incorporating teaching about chronic fatigue syndrome into the medical curriculum within the context of a biopsychosocial understanding of illness could encourage more positive attitudes towards chronic fatigue syndrome.
Sexuality Education and Desire: Still Missing after All These Years.

Nearly twenty years after the publication of Michelle Fine's essay "Sexuality, Schooling, and Adolescent Females: The Missing Discourse of Desire," the question of how sexuality education influences the development and health of adolescents remains just as relevant as it was in 1988. In this article, Michelle Fine and Sara McClelland examine the federal promotion of curricula advocating abstinence only until marriage in public schools and, in particular, how these policies constrict the development of "thick desire" in young women. Their findings highlight the fact that national policies have an uneven impact on young people and disproportionately place the burden on girls, youth of color, teens with disabilities, and lesbian/gay/bisexual/ transgender youth. With these findings in mind, the authors provide a set of research guidelines to encourage researchers, policymakers, and advocates as they collect data on, develop curricula for, and change the contexts in which young people are educated about sexual.
Knowing the Game: Integrating Speech and Action in Games Teaching Through TGfU

The “discursive turn” in the social sciences points to the potential in Teaching Games for Understanding pedagogy (TGfU) as a means of providing a holistic learning experience for students and a platform from which to reposition physical education among institutional forces that define boundaries between academic disciplines in the school curriculum. We argue that games taught in physical education using TGfU as a form educational conversation in which the mind, expressed in speech, and the body, expressed in action, embody the ideal holistic learning experience that simultaneously provides for cognitive, affective, social, and physical learning.
On resonant leptogenesis

It has been recently shown that the quantum Boltzmann equations may be relevant for the leptogenesis scenario. In particular, they lead to a time-dependent CP asymmetry which depends upon the previous dynamics of the system. This memory effect in the CP asymmetry is particularly important in resonant leptogenesis where the asymmetry is generated by the decays of nearly mass-degenerate right-handed neutrinos. We study the impact of the nontrivial time evolution of the CP asymmetry in resonant leptogenesis, both in the one-flavour case and with flavour effects included. We show that significant qualitative and quantitative differences arise with respect to the case in which the time dependence of the CP asymmetry is neglected.
A Case Study of SWIM: Optimization of Memory Intensive Application on GPGPU

Recently, GPGPU has been adopted well in the High Performance Computing (HPC) field. The limited global memory bandwidth poses a great challenge to many GPGPU programmers trying to exploit parallelism within the CPU-GPU heterogeneous platform. In this paper, we choose SWIM, a typical memory intensive application from the SPEC OMP 2001 benchmark suite, for case study. We attempt to optimize the performance and energy consumption of the application utilizing different memory access mechanisms and present optimization methods including matrix transposition and kernel fusion. The experimental results on the Intel Core TM i920 CPU plus GeForce GTX 295 platform shows that, the proposed optimizing methods achieve a speedup of 8.7X over the original OpenMP program and reduce the energy consumption by 83% for the problem size of 2048*2048.
Texplore- exploring expository texts via hierarchical representation

Exploring expository texts presents an interesting and important challenge. They are read routinely and extensively in the form of online newspapers, web-based articles, reports, technical and academic papers. We present a system, called Texplore, which assists readers in exploring the content of expository texts. The system provides two mechanisms for text exploration, an expandable outline that represents the hierarchical structure of the text, and a concept index, hot-linked to the concept references in the text. The hierarchical structure is discovered using lexical cohesion methods combined with hierarchical agglomerative clustering. The list of concepts are discovered by n-gram analysis filtered by part-of-speech patterns. Rather than the common presentation of documents by static abstracts, Texplore provides dynamic presentation of the text's content, where the user controls the level of detail.q. 1 I n t r o d u c t i o n Ever-faster computers, the Internet together with large information repositories linked by high-speed networks, are combined to provide immediate accessibility to large amounts of texts. The urgency of exploring these texts varies depending on the consumer students, researchers, professionals, decision makers, or just anybody. In any case the amounts of texts are beyond our ability to digest them. Research in information retrieval (IR) has been focused until now on the task of presenting relevant documents to the user. Commercial tools followed suit, as evident by the many powerful search engines now available on the Web. Typically, the relevant doo,ments are presented by some automatically computed abstract. Our work focuses on medium size and longer documents where the user needs some further assistance in exploring the content of the retrieved document. The idea then is to extend the applicability of IR methods, beyond the document retrieval, to the task of a reading assistant. We might expect from a reading assistant, or a text exploration tool, to provide us with two basic capabilities: 1. A controlled view of the content of the document. 2. The list of concepts discussed in the text. The first capability might be seen as an "electronic" table-of-contents, and is the key vehicle for efficient text exploration. The second can be seen as an "electronic" index, and provides an orthogonal access vehicle to the mechanism of a table-of-contents. We have implemented such a text exploration system in Texplore. It is designed for expository texts such as informative articles in magazines, technical reports and scientific papers. In Section 2 we discuss some characteristics of expository texts that make possible the development of the above text exploration capabilities. In Section 3 we focus on the importance of hierarchical representation of texts as a visualization tool. Section 4 details the Texplore system itself, ag~dn focusing on the hierarchical content representation. We conclude by discussing some shortcoming of the system and p]an.q for
Supersymmetric string waves.

We present plane-wave-type solutions of the lowest-order superstring effective action which have unbroken space-time supersymmetries. They are given by a stringy generalization of the Brinkmann metric, dilaton, axion, and gauge fields. Some conspiracy between the metric and the axion field is required. The alpha' stringy corrections to the effective on-shell action, to the equations of motion (and therefore to the solutions themselves), and to the supersymmetry transformations are shown to vanish for a special class of these solutions that we call supersymmetric string waves (SSW's). In the SSW solutions, there exists a conspiracy not only between the metric and the axion field, but also between the gauge fields and the metric, since the embedding of the spin connection in the gauge group is required.
Distributed Discovery in E-Science : Lessons from the Angle Project

We describe the design of a system called Angle that detects emergent and anomalous behavior in distributed IP packet data. Currently, Angle sensors are collecting IP packet data at four locations, removing identifying information, and building IP-based profiles in temporal windows. These profiles are then clustered to provide high-level summary information across time and across different locations. We associate meaningful changes in these cluster models with emergent or anomalous behavior. Emergent clusters identified in this way are then used to score the collected data in near real time. The system has a visual analytics interface, which allows different emergent clusters to be visualized, selected, and used for scoring of current or historical data. Each Angle sensor is paired with a node on a distributed computing platform running the Sector middleware. Using Sector, data can be easily transported for analysis or reanalysis.
A–Z of nutritional supplements: dietary supplements, sports nutrition foods and ergogenic aids for health and performance—Part 33

Quercetin was first introduced to our A–Z series in the article on flavonoids.1 In Part 33, the author of the flavonoid review, Dr Nieman, updates this topic. We also cover another intriguing plant-based compound with proposed benefits as an antioxidant and stimulator of mitochondrial biogenesis, resveratrol. Rhodiola rosea, a claimed adaptogen, concludes this issue. ### D C Nieman Epidemiological studies support multiple disease prevention benefits for individuals consuming foods rich in the flavonol quercetin. In vitro and animal studies indicate that quercetin is a strong antioxidant and anti-inflammatory agent, and exerts antipathogenic and immune regulatory influences.2 Quercetin supplementation studies in community-dwelling humans do not reflect these positive benefits, but research is continuing in order to determine the proper outcome measures, dosing regimen and adjuvants that may amplify any perceived bioactive effects of quercetin in vivo. Quercetin supplementation studies in athletes have focused on potential influences on post-exercise inflammation, oxidative stress and immune dysfunction, illness rates following periods of physiological stress and exercise performance. Results thus far have been negative for quercetin's countermeasure effects on postexercise physiological stress indicators, such as immune perturbations.3,–,5 However, when quercetin supplementation is combined with other polyphenols and food components such as green tea extract, isoquercetin and fish oil, a substantial reduction in exercise-induced inflammation and oxidative stress occurs in athletes, with augmentation of innate immune function.6 Quercetin exerts strong antiviral activities when cultured with a wide variety …
Combined endurance/resistance training reduces plasma TNF-alpha receptor levels in patients with chronic heart failure and coronary artery disease.

AIMS Physical reconditioning of patients with chronic heart failure (CHF) improves exercise capacity and restores endothelial function and skeletal muscle changes. The effects of 4 months combined endurance/resistance exercise training on cytokines and cytokine receptors in patients with CHF were studied. In addition, changes in submaximal and maximal exercise performance were addressed. METHODS AND RESULTS Twenty-three patients with stable CHF due to coronary artery disease (CAD, n=12) or idiopathic dilated cardiomyopathy (IDCM, n=11) were trained for 4 months. Blood sampling for measurement of plasma concentrations (ELISA) of interleukin (IL)-6, tumour necrosis factor (TNF)-alpha, soluble TNF receptor 1 (sTNFR1) and 2 (sTNFR2), as well as cardiopulmonary exercise testing were performed at baseline and after 4 months. Training induced a significant decrease in sTNFR1 (P=0.02) for the total population, and in both sTNFR1 (P=0.01) and sTNFR2 (P=0.02) concentrations for the CAD group only. IL-6 and TNF-alpha levels were not altered. Cytokine concentrations remained unchanged in an untrained age- and sex-matched control group. NYHA functional class, submaximal and maximal workrate were significantly improved in both patient groups. Oxygen uptake at the anaerobic threshold (P=0.002) and at peak exercise increased in the CAD patients only (P=0.008). CONCLUSION Besides an overall beneficial effect on exercise capacity, combined endurance/resistance exercise training has an anti-inflammatory effect in patients with CHD and CAD.
Control Points for Adaptive Parallel Performance Tuning

This paper describes a new parallel program tuning framework, with a new approach for tuning. The application exposes tuning parameters while an adaptive runtime system tunes the values of the parameters as the program executes. The parameters are allowed to vary throughout the duration of a run of a program. This provides two benefits over using a static set of parameters for each program run. The first is that parameters affecting performance may need to vary throughout the program run to achieve maximum performance. The second benefit is that many parameter configurations can be tested in a single run of an application. This approach amortizes the cost of startup across many evaluations of configurations in the parameter space. The framework can tune parameters across multiple modules in a parallel application. It can collectively optimize the parameters, called Control Points, exposed by the application, the runtime system, and libraries. This paper describes preliminary work using Control Points with two programs, a finite difference scheme, and a pipelined filtering application. Results from an exhaustive search of the configuration space are provided as a basis for determining which types of search strategies would be effective. The optimal configurations for control points vary between different parallel systems.
The Study of Design Research Methodology

Studies on design research methodology are infrequent, although there is a consensus that more effort is needed for improving design research quality. Previous calls for exercising better research methodology have been unsuccessful. As numerous studies reveal, there is no single scientific methodology that is exercised in science or in any other research practice. Rather, research methodologies are socially constructed. Since some constructions are better than others for different purposes, it becomes valuable to study different methodologies and their influence on research practice and results. Proposals for such studies are offered.
GEAS: Generic Adaptive Scheduling for High-Efficiency Context Inconsistency Detection

Context-aware applications adapt their behavior based on collected contexts. However, contexts can be inaccurate due to sensing noise, which might cause applications to misbehave. One promising approach is to check contexts against consistency constraints at runtime, so as to detect context inconsistencies for applications and resolve them in time. The checking is typically immediate upon each collected context change. Such a scheduling strategy is intuitive for avoiding missing context inconsistencies in the detection, but may cause low-efficiency problems for heavy-workload checking scenarios, even if equipped with existing incremental or parallel constraint checking techniques. One may choose to check contexts in a batch way to increase the efficiency by reducing the number of constraint checking. However, this can easily cause missed context inconsistencies, denying the purpose of inconsistency detection. In this paper, we propose a novel scheduling strategy GEAS of two nice properties: (1) adaptively tuning the batch window to avoid missing any context inconsistency; (2) generic to checking techniques with no or little adjustment. We experimentally evaluated GEAS against the immediate strategy with existing constraint checking techniques. The experimental results show that GEAS achieved 143-645% efficiency improvement without missing any context inconsistency, while alternatives caused 39.2-65.3% loss of detected context inconsistencies.
‘Steal me if you can!’ The impact of campaign messages on associative issue ownership

Whereas extant work on issue ownership treats voters’ issue ownership perceptions as independent variables to explain electoral choice or party behaviour, this article examines whether parties can, by communicating on an issue, turn voters' perceptions of issue ownership to their advantage. In contrast to most previous studies that have focused on competence ownership – measured as a party's capacity to handle an issue – this article analyses the short-term and long-term impact of campaign messages on voters' perceptions of associative ownership, which refers to the voters’ spontaneous party–issue association, regardless of whether or not voters consider the party as the most competent at dealing with the issue at hand. Based on an online experimental design in Belgium, we show that parties are unable to steal issues that are associated with another party. However, by communicating on their own issues, parties can reinforce their reputation as an associative owner – but only in the short run and only if their previous ownership reputation is not overly strong.
Analysis of Luteal Tissue Inhibitor of Metalloproteinase-1, -2, and -3 During Prostaglandin F2α-Induced Luteolysis1

Abstract Increased matrix metalloproteinase (MMP) expression and activities help to mediate tissue involution through increasing extracellular matrix remodeling and promoting dedifferentiation and, ultimately, apoptosis. Therefore, we hypothesized that prostaglandin (PG) F2α administration would decrease expression of the tissue inhibitor of metalloproteinase (TIMP)-1, -2, and -3 and effectively increase the MMP:TIMP ratio, leading to glandular involution. In experiment 1, we tested the effects of PGF2α administration (Day 10 postestrus; Day 0 = estrus) on luteal TIMP-1, -2, and -3 mRNA and protein expression. Corpora lutea were collected at 0, 15, or 30 min or at 1, 2, 4, 6, 12, 24, and 48 h following PGF2α administration (n = 3–9 animals/time point). Following PGF2α administration, TIMP-1 mRNA levels decreased (P < 0.05) at 1 and 2 h relative to 0 h (controls), then increased to levels greater than controls at 4 and 6 h. In contrast, TIMP-2 and -3 mRNA levels did not decrease following PGF2α administration. The TIMP-1, -2, and -3 proteins were localized to large luteal cells (LLCs) within control (untreated) tissues. However, histodepletion of TIMP-1 within LLCs was evident within 30 min (earliest time point collected) following PGF2α injection and continued through 48 h. Luteal concentration of TIMP-1, as determined by RIA, was decreased (P < 0.05) by 15 min (earliest time point collected) following PGF2α administration and remained low through 48 h. In contrast, TIMP-2 and -3 immunolocalization was not altered by PGF2α administration. Experiment 2 was conducted to determine if PGF2α could initiate the preceding changes in TIMP-1 in early (Day 3) corpora lutea that can bind PGF2α but are refractory to its luteolytic effects. Serum concentrations of progesterone and luteal concentrations of TIMP-1 mRNA and protein were similar at 0 and 6 h after PGF2α injection on Day 3 postestrus. These data suggest that an early and sustained effect of PGF2α is the specific depletion of TIMP-1 within LLCs that are capable of responding to the luteolytic action of PGF2α. This action may increase the MMP:TIMP-1 ratio, creating an environment that favors extracellular matrix degradation and, thereby, facilitates both functional and structural regression.
Design and Control of an EMG Driven IPMC Based Artificial Muscle Finger

The medical, rehabilitation and bio-mimetic technology demands human actuated devices which can support in the daily life activities such as functional assistance or functional substitution of human organs. These devices can be used in the form of prosthetic, skeletal and artificial muscles devices (Andreasen et al., 2005; Bitzer & Smagt, 2006; DoNascimento et al., 2008). However, we still have some difficulties in the practical use of these devices. The major challenges to overcome are the acquisition of the user’s intention from his or her bionic signals and to provide with an appropriate control signal for the device. Also, we need to consider the mechanical design issues such as lightweight and small size with flexible behavior etc (Arieta et al., 2006; Shenoy et al., 2008). For the bionic signals, the electromyography (EMG) signal can be used to control these devices, which reflect the muscles motion, and can be acquired from the body surface. We are familiar with the fact that ionic polymer metal composite (IPMC) has tremendous potential as an artificial muscle. This can be stimulated by supplying a small voltage of ±3V and shows evidence of a large bending behavior (Shahinpoor & Kim, 2001; 2002; 2004; Bar-Cohen, 2002). In place of the supply voltage from external source for actuating an IPMC, EMG signal can be used where EMG electrodes show a reliable approach to extract voltage signal from body (Jain et al. 2010a; 2010b; 2011). Using this voltage signal via EMG sensor, IPMC can illustrate the biomimetic behavior through the movement of human muscles. Therefore, an IPMC is used as an artificial muscle finger for the bio-mimetic/micro robot.
