Environmental influence on the seasonal movements of satellite-tracked ocean sunfish Mola mola in the north-east Atlantic

Determining the habitat use of mobile marine species is important for understanding responses to climate change and aids the implementation of management and conservation measures. Inference of preferred habitat use has been greatly improved by combining satellite-based oceanographic data with animal tracking techniques. Although there have been several satellite-tracking studies on ocean sunfish Mola mola, limited information is available about either horizontal or vertical environmental preferences. In this study, both geographical movements and diving behaviour of ocean sunfish were explored together with the environmental factors influencing this species’ space use in the north-east Atlantic.

The Internet as opportunity and challenge in contemporary social movements

This paper explores the relationship between the rise of “new” social movements (15-M and Occupy) and the Internet. The new social media gives rise to new kinds of social movements  which embed this technology from the moment of conception. The future of social movements will be characterised by movinets, which will have the effect of developing new efficient ways of activism. The movinets, with their embedded technology and capacity to circulate ideas among different spheres of reality, have a potential to alter the dynamics of social mobilisation.

On processing GPS tracking data of spatiotemporal car movements : a case study

The advancement of GPS technology has made it possible to use GPS devices as orientation and navigation tools, but also as tools to track spatiotemporal information. GPS tracking data can be broadly applied in location-based services, such as spatial distribution of the economy, transportation routing and planning, traffic management and environmental control. Therefore, knowledge of how to process the data from a standard GPS device is crucial for further use. Previous studies have considered various issues of the data processing at the time. This paper, however, aims to outline a general procedure for processing GPS tracking data. The procedure is illustrated step-by-step by the processing of real-world GPS data of car movements in Borlänge in the centre of Sweden.

Fetal Movements in late Pregnancy : Categorization, Self-assessment, and Prenatal Attachment in relation to women’s experiences

Aim: To explore how pregnant women experience fetal movements in late pregnancy. Specific aims were:  to study women’s experiences during the time prior to receiving news that their unborn baby had died in utero (I), to investigate women’s descriptions of fetal movements (II), investigate the association between the magnitude of fetal movements and level of prenatal attachment (III), and to study women’s experiences using two different self-assessment methods (IV). Methods: Interviews, questionnaires, and observations were used. Results: Premonition that something had happened to their unborn baby, based on a lack of fetal movements, was experienced by the participants. The overall theme “something is wrong” describes the women’s insight that the baby’s life was threatened (I). Fetal movements that were sorted into the domain “powerful movements” were perceived in late pregnancy by 96 % of the participants (II). Perceiving frequent fetal movements on at least three occasions per 24 hours was associated with higher scores of prenatal attachment in all the three subscales on PAI-R. The majority (55%) of the 456 participants reported average occasions of frequent fetal movements, 26% several occasions and 18% reported few occasions of frequent fetal movements, during the current gestational week.  (III). Only one of the 40 participants did not find at least one method for monitoring fetal movements suitable. Fifteen of the 39 participants reported a preference for the mindfetalness method and five for the count-to-ten method. The women described the observation of the movements as a safe and reassuring moment for communication with their unborn baby (IV). Conclusion:  In full-term and uncomplicated pregnancies, women usually perceive fetal movements as powerful. Furthermore, women in late pregnancy who reported frequent fetal movements on several occasions during a 24-hour period seem to have a high level of prenatal attachment. Women who used self-assessment methods for monitoring fetal movements felt calm and relaxed when observing the movements of their babies. They had a high compliance for both self-assessment methods. Women that had experienced a stillbirth in late pregnancy described that they had a premonition before they were told that their baby had died in utero. 

On the Movements of the North Atlantic Subpolar Front in the Preinstrumental Past*

Three sediment records of sea surface temperature (SST) are analyzed that originate from distant locations in the North Atlantic, have centennial-to-multicentennial resolution, are based on the same reconstruction method and chronological assumptions, and span the past 15 000 yr. Using recursive least squares techniques, an estimate of the time-dependent North Atlantic SST field over the last 15 kyr is sought that is consistent with both the SST records and a surface ocean circulation model, given estimates of their respective error (co)variances. Under the authors' assumptions about data and model errors, it is found that the 10 degrees C mixed layer isotherm, which approximately traces the modern Subpolar Front, would have moved by ~15 degrees of latitude southward (northward) in the eastern North Atlantic at the onset (termination) of the Younger Dryas cold interval (YD), a result significant at the level of two standard deviations in the isotherm position. In contrast, meridional movements of the isotherm in the Newfoundland basin are estimated to be small and not significant. Thus, the isotherm would have pivoted twice around a region southeast of the Grand Banks, with a southwest-northeast orientation during the warm intervals of the Bolling-Allerod and the Holocene and a more zonal orientation and southerly position during the cold interval of the YD. This study provides an assessment of the significance of similar previous inferences and illustrates the potential of recursive least squares in paleoceanography.

Accidents at work by excessive efforts / inappropriate movements in nurses

Nurses continuously develop various activities that expose them to excessive force and inappropriate movements. Characterize the accidents reported by overexertion and inappropriate movements in Portuguese nurses during 2009 and 2010. Retrospective cross-sectional study, covering the period from January 1, 2009 to December 31, 2010. Were defined as inclusion criteria, be nurse and having notified by excessive straining and improper motion accident. The information was obtained by reference to the computer record of accidents at work General Administration of Health Services, relating to 672 nurses. There were 672 notifications of accidents by overexertion/ inappropriate moves in Portuguese nurses. The higher prevalence of these accidents was in nurses with over 10 years of service 277 (41.2%), 565 were female (42.6%) in the age group 25-29 (29.9%) and practice time for 555 shifts (82.6%). At admission there were 387 (57.3%) within 3 hours of work 330 (49.1%) and the third day after weekly rest 216 (32.1%). The Mobilization of patients was the most frequent cause of this accident 430 (64.0%). The main effects were the sprains and strains 321 (47.8%), mainly the trunk reached 367 (54.7%) and absenteeism caused 373 (55.5%). On average 17.7 days missed a total of 12.054 days. There was a high prevalence of accidents during the mobilization of prayer on patients so importante to invest in the implementation of mechanical equipment for the mobilization and transport of patients.
