Análisis de los discursos de los y las jóvenes sobre la violencia en las relaciones de pareja

La violencia en las relaciones de pareja es actualmente uno de los problemas sociales serios con los que se enfrenta esta sociedad. La gravedad de esta problematica se intensifica a la luz de los datos que configuran que la violencia que se ejerce en las primeras relaciones de pareja entre adolescentes, comienzan cada vez a una edad mas temprana, situando los primeros episodios violentos entre 11 y 17 anos. Esta violencia en las relaciones de pareja abarca tanto aquellas que se producen en parejas que llevan juntas mucho tiempo como en parejas que estan empezando su relacion de noviazgo. La mayoria de los estudios de violencia en las relaciones de pareja de los/as adolescentes son de corte cuantitativo y se centran en determinar la prevalencia del problema. El objetivo de nuestro estudio basado en una metodologia cualitativa, consiste en analizar la violencia en las relaciones de pareja de los/as adolescentes a traves de sus propios discursos a traves de grupos de discusion. Para ello, se llevo a cabo un total de cuatro grupos de discusion, dos en el segundo ciclo de la Educacion Secundaria Obligatoria y otros dos en Bachillerato en un Instituto de Educacion Secundaria de la ciudad de Ourense. En total participaron 40 estudiantes con edades comprendidas entre 15 y 18 anos, de los cuales 21 son chicos y 19 son chicas. Todos/as los/as adolescentes de la muestra accedieron a participar de forma voluntaria en el estudio tras previa comunicacion a los padres/madres por parte del tutor o jefe de estudios. En el grupo de discusion se les plantearon cuestiones relativa a que significa una relacion de pareja, que entendian por violencia en las relaciones de pareja o noviazgo entre adolescentes, si conocian algun amigo/a que sufriera este tipo de violencia de pareja, se les pregunto tambien sobre cuales creian que eran las razones por las que se puede actuar con violencia hacia la parece. Los resultados nos evidencian que chicos y chicas muestran percepciones de las relaciones de pareja, las chicas siguen mostrando en sus discursos visiones mas romanticas del amor, y siguen considerando los celos como una muestra de amor. En cuanto a la violencia ejercida en las parejas de adolescentes, son muchas chicas las que afirman conocer distintos casos de amigas que sufren violencia fisica leve y violencia psicologica/verbal. Tambien los chicos manifiestan conocer casos de violencia verbal por parte de sus parejas femeninas. En cuanto a las razones que senalan para que algunos/as actuen con violencia hacia sus parejas, son principalmente los celos y el consumo excesivo de alcohol u otras drogas. Destacar que un par de chicas manifestaron que cuando una chica “insulta” a su pareja es para defenderse de los ataques de su pareja. Por lo tanto, estos resultados evidencian que la violencia de genero tambien esta presente en la vida de los/as adolescentes, con lo cual es importante trabajar con este colectivo desde una perspectiva coeducativa que fomente el buen trato y una educacion sin violencia.
Determining factors for carotid mean/max intima-media thickness and brachial flow-mediated dilation in healthy young women

Background: Many factors can contribute to atherosclerotic-type vascular changes in older individuals or men. Thus, confining the investigation to young women with no clinical evidence of the condition could enhance understanding of the early stages of cardiovascular disease. The aim of this study was to determine whether carotid mean/max intima-media thickness (IMT) and brachial flow-mediated dilation (FMD) values, which are well-known event-related indices, are associated with laboratory data and the other vascular indices of atherosclerosis in healthy young women. Methods: Carotid mean/max IMT and brachial FMD were measured in young women with no clinical evidence of atherosclerosis (n = 110; mean age, 39 years) who were instructed not to eat, drink or smoke after 9 PM the evening before testing. All participants also underwent laboratory assessment, including simultaneous measurements of arterial stiffness such as augmentation index (AI), cardioankle vascular index (CAVI) and brachial-ankle pulse wave velocity (baPWV). Results: Mean IMT was signifi-cantly and positively associated with age (p = 0.002), CAVI (p = 0.044), low-density lipoprotein-cholesterol (LDL-C, p = 0.047) and high-sensitive C-reactive protein (hs-CRP, p = 0.002) values but was not related to FMD, AI, baPWV or triglycerides (TG) in the multivariate regression analysis. Similarly, max IMT was positively associated with age (p p = 0.003) and hs-CRP (p = 0.005) values but was not related to FMD, AI, CAVI, baPWV, TG or blood pressure level in the multivariate regression analysis. The association between LDL-C and max IMT was much stronger than that between LDL-C and mean IMT. Brachial FMD was positively associated only with heart rate in the multivariate regression analysis. Conclusions: These results suggest that mean IMT more closely represents the sclerotic aspect of vascular change, whereas max IMT represents the atherotic aspect in healthy young women. Although the relationship between the autonomic nervous system and heart rate is well-known, there may be a complex interaction between the autonomic nervous system and endothelial function.
Exposure to direct and scatter radiation with use of mini-C-arm fluoroscopy.

To The Editor: We commend Giordano et al. on their excellent work in quantifying the risk of radiation when using a mini-C-arm fluoroscopy unit, as reported in their study entitled “Exposure to Direct and Scatter Radiation with Use of Mini-C-Arm Fluoroscopy” (2007;89:948-52). Their methodology, however, does not accommodate for the measurement of increased radiation exposure when the C-arm is used in the conventional method, with the image …

Seulement 3 especes (environ 6%) ont ete echantillonnees en foret. Les especes exploitees renferment pres de 42% d’herbacees et de 58% de ligneux. Les fragments ou organes les plus utilises comprennent les feuilles, les fruits, les graines et les ecorces.
The Automatic Classification of Fault Trigger Based Bug Report

Understanding the types of defects is of practical interest, which could help developers adopt proper measures in current and future software releases. As the amount of bug reports increasing, manual classification brings a heavy burden to developers. In this paper, we propose a word2vec based framework of multi-granularity automatic classification for bug reports based on fault triggers. Except classifying bug reports into bug/non-bug and Bohrbug/Mandelbug, the classification of Mandelbugs is the focus of this paper. Characteristic representation of common classification methods suffer from data sparsity and high dimensionality, thus we use word2vec, which can express words as low-dimensional word vectors with semantic relations in this paper. Furthermore, in order to improve the quality of classification, we analyzed the impact factors of classification. The results show that our method performs well in automatic classifying bugs into fault trigger classes.
The variable choice set logit model applied to the 2004 Canadian election

Formal work on the electoral model often suggests that parties should locate at the electoral mean. Recent research has found no evidence of such convergence. In order to explain non-convergence, the stochastic electoral model is extended by including a competence and sociodemographic valance in a country where regional and national parties compete in the election. That is, the model allows voters to face different sets of parties in different regions. We introduce the notion of a convergence coefficient, c for regional and national parties and show that when c is high there is a significant centrifugal tendency acting on parties. An electoral survey of the 2004 election in Canada is used to construct a stochastic electoral model of the election with two regions: Québec and the rest of Canada. The survey allows us to estimate voter positions in the policy space. The variable choice set logit model is used to built a relationship between party position and vote share. We find that in the local Nash equilibrium for the election the two main parties with high competence valence, the Liberals and Conservatives, locate at the national electoral mean and the Bloc Québécois, with the highest competence valence, locates at the Québec electoral mean. The New Democratic Party has a low competence valence but remains at the national mean. The Greens, with lowest competence valence, locate away from the national mean to increase its vote share.
Is cardiac rehabilitation fit for purpose in the NHS: maybe not

The scientific evidence for cardiac rehabilitation is strong with reductions in total and cardiac mortality of 13% and 26% respectively in randomised controlled trials comparing rehabilitation to usual care.1 However, this evidence largely pre-dates acute revascularisation, initially by thrombolysis and then angioplasty, and the widespread use of cardioprotective medications, also reducing total mortality.2 So RAMIT (Rehabilitation after myocardial infarction trial) asked the seminal question does cardiac rehabilitation, as provided by the NHS, further reduce total mortality and morbidity and improve health related quality of life in the context of cardiology practice in the late 90s? 3 It did not ( see page 637 ). In this multicentre parallel group trial hospitals already running a cardiac rehabilitation programme, fourteen of them, agreed to randomise patients following myocardial infarction to their own programme or to usual care. These programmes reportedly conformed to guidelines issued by the British Association for Cardiac Rehabilitation and comprised exercise training, health education about heart disease, risk factors and treatment, counselling for recovery and advice for long term secondary prevention.4 Exercise training was described as the largest component using equipment in physiotherapy gyms. The primary endpoint was total mortality at 2 years and a sample size of 8000 patients was required to detect a 20% RR reduction compared to usual care. In the event only 1813 patients were randomised between 1997 and 2000, before the money ran out, with 903 allocated to rehabilitation and 910 to usual care. Baseline characteristics were almost identical. With less than a quarter of patients recruited out of the total originally planned the trial was far too weak to assess the primary endpoint. At 2 years the number of deaths in cardiac rehabilitation and usual care were almost identical. So this complete cohort of trial patients was carefully followed up for all cause …
Models to Study Ischemia in Chronic Wounds

Wound healing is a complex immune response designed to achieve tissue repair following injury. Imbalance of stimulating and inhibiting factors cause failure of healing. Ischemia is a major cause of wound repair dysregulation and may be limb and life threatening. Investigating ischemic wound healing using animal models minimizes the complex accompanying factors that are usually present in humans, such as age or diabetes. This paper presents a limited review on normal physiological healing and on models that are used to study compromised healing under ischemic conditions.
Topology bounds energy of knots and links

In this paper, we determine two quantities, of geometric and topological character, that were left undetermined in two previous results obtained by Arnold (Arnold 1974 In Proc. Summer School in Diff. Eqs. at Dilizhan, pp. 229–256.) and Moffatt (Moffatt 1990 Nature 347, 367–369) on lower bounds for the magnetic energy of knots and links in ideal fluids. For dissipative systems, a lower bound on magnetic helicity in terms of the average crossing number and a new relationship between rates of change of these two quantities are also determined.
Effects of Pituitary Adenylate Cyclase‐Activating Polypeptide and Vasoactive Intestinal Polypeptide on Food Intake and Locomotor Activity in the Goldfish, Carassius auratus

Abstract: We investigated the effects of intracerebroventricular (ICV) and intraperitoneal (IP) administration of pituitary adenylate cyclase‐activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP) on food intake in the goldfish, Carassius auratus. Cumulative food intake was significantly decreased by ICV injection of PACAP or VIP. Similarly, IP administration of PACAP or VIP induced a significant decrease in food intake. ICV injection of PACAP or VIP also induced a significant decrease in locomotor activity. These results suggest that PACAP and VIP may be involved in the regulation of feeding in goldfish.
Synthesis of mot and che gene products of Escherichia coli programmed by hybrid ColE1 plasmids in minicells

Hybrid Escherichia coli ColE1 plasmids carrying the genes for motility (mot) and chemotaxis (che) were transferred to a minicell-producing strain. The mot and che genes on the hybrid plasmid directed protein synthesis in minicells. Polypeptides synthesized in minicells were identical to the products of the motA, motB, cheA, cheW, cheM, cheX, cheB, cheY, and cheZ genes previously identified by using hybrid lambda and ultraviolet-irradiated host cells (Silverman and Simon, J. Bacteriol. 130:1317-1325, 1977), thus confirming these gene product assignments. The products of some che genes (cheA and cheM) appeared as more than one band on polyacrylamide gel electrophoresis, but analysis of partial peptide digests of these polypeptides suggested that the multiple forms were coded for by a single gene. Measurement of the physical length of the hybrid plasmids allowed an estimate of the amount of coding capacity of the cloned deoxyribonucleic acid, which was devoted to the synthesis of the mot and che gene products. These estimates were also consistent with the hypothesis that the multiple polypeptides corresponding to cheA and cheM were the products of single genes.
Location, Location, Location: An Analysis of Profitability of Position in Online Advertising Markets

The authors evaluate the impact of ad placement on revenues and profits generated from sponsored search. Their approach uses data generated through a field experiment for several keywords from an online retailer's ad campaign. Using a hierarchical Bayesian model, the authors measure the impact of ad placement on both click-through and conversion rates. They find that while click-through rate decreases with position, conversion rate increases with position and is even higher for more specific keywords. The net effect is that, contrary to the conventional wisdom in the industry, the topmost position is not necessarily the revenue-or profit-maximizing position. The authors’ results inform the advertising strategies of firms participating in sponsored search auctions and provide insight into consumer behavior in these environments. Specifically, they help correct a significant misunderstanding among advertisers regarding the value of the top position. Furthermore, they reveal potential inefficiencies in current auction mechanisms that search engines use. The authors’ results also reveal the information search strategies that consumers use in sponsored search and provide evidence of recency bias for immediate purchases.
Smoking Reduction for Smokers Not Able or Motivated to Quit?

Smoking reduction, i.e. a sustained decrease in the number of cigarettes smoked daily, is a highly controversial area. Results from population studies are reported as well as from the few randomized controlled studies published. The effect with regard to smoking reduction seems small and there is only limited evidence that smoking reduction is followed by improvement in some health-related parameters. More biomarkers of smoking reduction need to be examined specially with regard to carcinogenic biomarkers. Smoking reduction seems to be of interest for smokers not motivated or able to quit, as a small percent of this group quit smoking during reduction trials. Further research is needed to evaluate the value of this concept. However, smoking cessation is still the ultimate goal.
Identifying multiplanar knee laxity profiles and associated physical characteristics.

CONTEXT A single measure of knee laxity (ie, measurement of laxity in a single plane of motion) is probably inadequate to fully describe how knee joint laxity is associated with anterior cruciate ligament injury. OBJECTIVE To characterize interparticipant differences in the absolute and relative magnitudes of multiplanar knee laxity (ie, sagittal, frontal, and transverse planes) and examine physical characteristics that may contribute to these differences. DESIGN Descriptive laboratory study. SETTING University research laboratory. PATIENTS OR OTHER PARTICIPANTS 140 participants (90 women, 50 men). MAIN OUTCOME MEASURE(S) Using cluster analysis, we grouped participants into distinct multiplanar knee laxity profiles based on the absolute and relative magnitudes of their anterior knee laxity (AKL), genu recurvatum (GR), and varusvalgus (VV) and internal-external rotation (IER) knee laxity. Using multinomial logistic regression, we then examined associations between the different laxity profile clusters and physical characteristics of sex, age, activity level, general joint laxity, body mass index, thigh strength, and 8 measures of lower extremity anatomical alignment. RESULTS Six clusters were identified: low (LOW), moderate (MOD) and high (HIGH) laxity overall and disproportionally higher VV/IER (MOD(VV/IER)), GR (HIGH(GR)), and AKL (HIGH(AKL)) laxity. Once all other physical characteristics were accounted for, the LOW cluster was more likely to be older, with longer femur length. Clusters with greater magnitudes of VV and IER laxity were more likely to be younger and to have lower body mass index, smaller Q-angle, and shorter femur length (MOD, HIGH, MOD(VV/IER)) and less thigh strength (HIGH). The HIGH(GR) cluster was more likely to be female and to have a smaller tibiofemoral angle and longer femur length. The HIGH(AKL) cluster was more likely to have greater hip anteversion and navicular drop. CONCLUSIONS The absolute and relative magnitudes of a person's multiplanar knee laxity are not always uniform across planes of motion and can be influenced by age, body composition, thigh strength, and structural alignment. Except in HIGH(GR), sex was not a significant predictor of cluster membership once other physical characteristics were taken into account.
Self–Criticism, Goal Motivation, and Goal Progress

The current research examined the relations among self-criticism, autonomous versus controlled motivations, and goal progress. Recent researchers have suggested that self-critics are less autonomously motivated, that is, that their goals are less tied to their interests and personal meaning than is true for other individuals, and that the effects of self-criticism on goal progress are mediated by lower levels of autonomous motivation. The results of two short-term, prospective studies conducted in the United States and Canada indicated that self-criticism was negatively associated with goal progress, while autonomous motivation was positively associated with goal progress in one study and marginally associated in the other. The results demonstrated an association between self-criticism and controlled motivation but not autonomous motivation, and they suggest that self-criticism and autonomy act independently on goal progress. In addition, the results indicated an association between self-criticism and rumination and procrastination that appears to mediate the impact of self-criticism on goal progress. These results highlight the need for consideration of both personality and motivational influences in the study of goal pursuits.
Abfraction and Anisotropy--Effects of Prism Orientation on Stress Distribution

This work discusses the effect of enamel anisotropy in the stress concentration at the cement-enamel junction (CEJ), a probable cause of fracture in enamel leading to abfraction. Usual simplifications when developing computer models in dentistry are to consider enamel isotropic, or that the direction of the prisms is orthogonal to either the dentine-enamel interface or the tooth outer surface. In this paper, a more refined model for the material behavior is described, based on laboratory observation and on the work of Fernandes and Chevitarese [1] . The material description is used in a two-dimensional (2D) finite element model of the first upper premolar, and the analysis is performed for two different situations: vertical loads, typical of normal mastication and horizontal loads, dominant in bruxism. The analyses were performed using a unit load, which under the hypothesis of linear response of the tooth, allows the combinations described in the text to simulate different functional and parafunctional loads. The results indicate that a realistic enamel description in terms of mechanical properties and spatial distribution of its prisms alters significantly the resulting stress distribution. For all cases included in this study, the detailed description of prism orientation and resulting anisotropy led to improved response in terms of stress distribution, even when loading was horizontal.
