Objectively measured sedentary time and physical activity time across the lifespan: a cross-sectional study in four age groups
Spittaels Heleen,Van Cauwenberghe Eveline,Verbestel Vera,De Meester Femke
International Journal of Behavioral Nutrition and Physical Activity , 2012, DOI: 10.1186/1479-5868-9-149
Abstract: Background From a health perspective it is suggested to promote a positive balance between time spent in light intensity physical activity (LIPA) and sedentary behaviour (SB) (i.e. spending more time in LIPA than time spent in SB). However, no studies have reported prevalence rates of the LIPA-SB balance yet. The aim of this study was to objectively investigate the time spent in SB, in LIPA and moderate-to-vigorous intensity physical activity (MVPA) in four Belgian age groups and to explore which proportion of the population had a favorable balance between LIPA and SB and combined this with recommended amount of MVPA. Methods Accelerometer data from 7 cross-sectional studies (N=2083) in four age groups (preschoolers, primary schoolchildren, secondary schoolchildren and adults) were aggregated. Differences in SB and PA between age groups and between men and women were determined by two-way MANCOVA. LIPA-SB balance was calculated and participants were categorized into one of four groups: (1) positive LIPA-SB balance (LIPA> SB) & sufficient MVPA (2) negative LIPA-SB balance & sufficient MVPA (3) positive LIPA-SB balance & insufficient MVPA (4) negative LIPA-SB balance & insufficient MVPA. Results For the total sample, 55% of the waking time was spent in SB, 39% in LIPA and 6% in MVPA. Differences in SB between age groups was dependent from gender (p<0.001). Further, a positive LIPA-SB balance was assessed in 18% of the total sample and only 10% combined this positive balance with recommended amount of MVPA. Secondary schoolgirls were most at risk, with only 1% of the sample combining a positive LIPA-SB balance with sufficient MVPA. Another risk group was the large proportion (43%) of adult men who combined sufficient MVPA with a negative LIPA-SB balance. Conclusion A high proportion of the Belgian population is at risk if taking into account both SB and PA levels. Secondary schoolgirls have the unhealthiest SB and PA profile and are therefore an important target group for interventions both increasing MVPA and decreasing SB. In men more attention should be given in promoting a positive LIPA-SB balance independently from their compliance with the MVPA guidelines.

Abstract: The intervention mapping protocol (IMP) was used to develop the community-based intervention for the prevention of childhood obesity in 3 to 10 years old children. It is a theory- and evidence-based tool for the structured planning and development of health promotion programs that requires the completion of six different steps. These steps were elaborated by two coordinating centers and discussed with the other participating centers until agreement was reached. Focus group research was performed in all participating centers to provide an informed basis for intervention development.The application of the IMP resulted in an overall intervention framework with ten intervention modules targeting environmental and personal factors through the family, the school and the community. The summary results of the focus group research were used to inform the development of the overall intervention. The cultural adaptation of the overall intervention was realised by using country specific focus group results. The need for cultural adaptation was considered during the entire process to improve program adoption and implementation. A plan was developed to evaluate program effectiveness and quality of implementation.The IDEFICS project developed a community-based intervention for the prevention of childhood obesity by using to the intervention mapping heuristic. The IDEFICS intervention consists of a general and standardized intervention framework that allows for cultural adaptation to make the intervention feasible and to enhance deliverability in all participating countries. The present manuscript demonstrates that the development of an intervention is a long process that needs to be done systematically. Time, human resources and finances need to be planned beforehand to make interventions evidence-based and culturally relevant.The prevalence of overweight and obesity in Europe has increased during the past decades [1,2] and is considered a significant public health problem [2].

Second Language Acquisition: Reconciling Theories  [PDF]
Vera Menezes
Open Journal of Applied Sciences (OJAppS) , 2013, DOI: 10.4236/ojapps.2013.37050
Abstract:

This article argues that previous attempts to explain SLA should not be disregarded. Instead, when they are put together, they provide a broader and deeper view of the acquisition process. There is evidence to support the claim that second language acquisition (SLA) is a complex adaptive system due to its inherent ability to adapt to different conditions present in both internal and external environments. Based on this understanding, widely discussed second language theories, including behaviorism, will be treated as explanations of parts of a whole, since each captures a different aspect of SLA. In order to justify this assumption, excerpts from some English language learning histories are provided to exemplify how learners describe their learning processes. The final claim is that SLA should be seen as a chaotic/complex system.

Improved Retrieval of Sea Ice Thickness and Density from Laser Altimeter  [PDF]
Vera Djepa
Atmospheric and Climate Sciences (ACS) , 2014, DOI: 10.4236/acs.2014.45080
Abstract: The sensitivity of weather and climate system to sea ice thickness (SIT) in the Arctic is recognised from various studies. Decrease of SIT will affect atmospheric circulation, temperature, precipitation and wind speed in the Arctic and remotely. Ice thermodynamics and dynamic properties depend strongly on ice and snow thickness. The heat transfer through ice critically depends on ice thickness. Long term accurate SIT records with corresponding uncertainties are required for improved seasonal weather forecast and estimate of the sea ice mass balance. Satellite radar and Laser Altimeter (LA) provide long term records of sea ice freeboard. Assuming isostatic equilibrium, SIT is retrieved from the freeboard, extracted from radar altimeter (RA) or LA, where the snow depth, density, ice and water density are input variables in the equation for hydrostatic equilibrium to derive SIT from LA or RA. Different input variables (snow depth, density, ice and water density) with unknown accuracy have been applied from various authors to retrieve SIT and Sea Ice Draft (SID) from RA or LA, leading to not comparative results. Sea ice density dependence on ice type, thermodynamic properties and freeboard is confirmed with different studies. Sensitivity analyses confirm the great impact of sea ice density, snow depth and density on accuracy of the retrieved SIT and the importance of inserting variable ice density (VID) in the equation for hydrostatic equilibrium for more accurate SIT retrieval, weather and climate forecast. The impact of sea ice density and snow depth and density on retrieved SIT from the freeboard derived from LA and RA have been analyzed in this study using the equation for hydrostatic equilibrium, statistical and sensitivity analyses. An algorithm is developed to convert the freeboard, derived from LA in SIT, inserting VID in the equation for hydrostatic equilibrium. The algorithm is validated with field, laboratory studies and collocated SIT retrieved from RA on board Envisat. The accuracy of the developed algorithm is analyzed, using statistical and uncertainty analyses. It is found that the uncertainty of the retrieved SIT from LA is decreased 7.6 times (from rhi = 59 cm for fixed ice density) if variable ice density is inserted in the equation for hydrostatic equilibrium. The SIT, which has been retrieved from the freeboard derived from LA is validated with collocated SIT derived from RA2 on Envisat, using variable ice density. The bias of the mean SIT derived from LA and RA has been reduced from -1.1 m to about one millimeter when VID is
Music, Eurocentrism and Identity: The Myth of the Discovery of America in Chilean Music History  [PDF]
Alejandro Vera
Advances in Historical Studies (AHS) , 2014, DOI: 10.4236/ahs.2014.35024
Abstract: During the past century, Edmundo O’Gorman, Tzvetan Todorov, Enrique Dussel and other scholars pointed out the Eurocentric perspective implied in traditional narratives about the discovery of America, most of which intended to confirm Europe as the center of world history and culture. At the same time, Claude Lévi-Strauss, Hayden White and others argued for the mythical character of history. According to them, even though historians attempted to assemble documentary evidence objectively, they constructed their narratives incorporating such evidence in preexisting stories, characters and categories with a mythical origin. This paper uses these viewpoints to analyze and criticize the way in which Chilean music history has been constructed, particularly during the republican era. The main hypothesis is that traditional discourses about that history have constantly recycled narratives on the discovery of America, which thus operates as a kind of founding myth for historical and musicological interpretations, especially when dealing with turning points such as the change of dynasty (1700), the beginning of independence (c. 1810) and the centenary of the republic (1910). A corollary would be that documentary evidence about music has been frequently hidden or distorted precisely in order to fit such a myth. That is why the present paper examines both bibliography and original documents found in different archives.
The Effect of a Mother’s Level of Attachment and Her Emotional Intelligence on a Child’s Health during Its First Year of Life  [PDF]
Elena Nikolaeva, Vera Merenkova
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.45068
Abstract:

The aim of this study was to investigate the possibility of predicting the health of a child during its first year by using the mother’s emotional intelligence and the level of her attachment to the child. Serving as test subjects were 50 mother-child pairs during the first year of life and 50 mother-child pairs during the second year of life (altogether 200 individuals). It was shown that the likelihood of dismissing a diagnosis given to a child at a maternity clinic depends on the level of the mother’s acceptance of the child and not on her emotional intelligence and anxiety.

Sem mágicas solu??es: a preven??o e o cuidado em HIV/ AIDS e o processo de emancipa??o psicossocial
Paiva, Vera;
Interface - Comunica??o, Saúde, Educa??o , 2002, DOI: 10.1590/S1414-32832002000200003
Abstract: this text discusses the need to politicize psycho-educational arenas and presents the idea of a "psycho-social emancipation" as one of the references for improved operationalization of the notion of vulnerability in the field of prevention of new hiv infections and of the organization of care for those who are aids carriers. reflecting on actions designed to encourage patients to take their medication and use condoms, it suggests that the prevention of hiv should overcome models devised for "hiv negative" people and that the prevent-assist continuum should be radicalized. to this end, it is pressing to: take into account the facts accumulated in the field of cultural analyses and of psychosocial research in the planning and organization of preventive actions and of providing assistance to hiv carriers, including, for instance, the ideas of oppressive social construction of two genders, masculine and feminine; overcome the notion of "individuals as consumers" (of services, educational programs, condoms and prescribed medication, of behaviors and safe practices to be practiced); foster the innovation of prevention and care actions. working with the idea of a "subject-citizen individual", co-participant in the psycho-educational arenas whose horizon consists of psychosocial emancipation, can enhance the quality of preventive actions and of integrated care of hiv and aids patients, so as to include "all" brazilians, according to the socio-cultural context of "each one", both men and women, testing positive or negative.
UNA NUEVA ESPECIE DE CHILENOPERLA (PLECOPTERA: GPJPOPTERYGIDAE) Y LAS CONSECUENCIAS TAXONóMICAS DEL DESCUBRIMIENTO DE SU NINFA
Vera,Alejandro;
Gayana (Concepción) , 2008, DOI: 10.4067/S0717-65382008000200005
Abstract: anew species of gripopterygidae (chilenoperla elongata sp. nov.) is described based on adults of both sexes and nymphs from chile. the nymph was associated by means of growing in controlled conditions. the nymph of the new species is similar to that oí pelurgoperla (sensu lilies, 1963). therefore, previous identifications and geographic distributions of these genera could be wrong. comments on the nymph of ch. puerilis are advanced at the light of this new finding.
