CONSTRUÇÃO E VALIDAÇÃO DE UMA ESCALA DOS ATRIBUTOS PESSOAIS DA RESILIÊNCIA

Resiliência é um termo relativamente novo no campo da psicologia e nos debates acadêmicos e que tem suscitado muito interesse por parte dos pesquisadores, em especial os do campo da Psicologia da Saúde, pois se trata de um conceito que carrega grande potencial em termos de prevenção de doenças e promoção da saúde, seja focado no plano social, comunitário ou individual. Em resumo, resiliência consiste na capacidade dos seres humanos de superarem as adversidades da vida e, além disso, saírem fortalecidos após uma situação problema. Estudos têm mostrado que pessoas consideradas resilientes possuem atributos pessoais que as ajudam a obter êxito diante das adversidades. No entanto, as medidas do construto não representam essa abrangência. Por isso, o objetivo deste estudo foi construir e validar uma escala que avalie as características pessoais mais referenciadas na literatura. No total, foram identificados 15 atributos pessoais da resiliência mencionados por mais de cinco autores. Com base neles foi construída a Escala dos Pilares da Resiliência (EPR) com 150 itens. Participaram da coleta de dados 833 estudantes e trabalhadores do Estado de São Paulo e Santa Catarina, com idade média de 30,70 (DP= 10,58), sendo a maioria do gênero feminino (70,5%) e solteiros(as) (59,8%) com escolaridade de ensino fundamental até pós-graduação. Por meio de um questionário coletaram-se dados sociodemográficos dos participantes. Foram calculadas estatísticas descritivas, análise fatorial, correlação item-total e alfa de Cronbach. Os resultados revelaram um modelo de 11 fatores que reuniram 90 itens com boas cargas fatoriais. As correlações item-total tiveram valores considerados satisfatórios e os fatores apresentaram bons índices de precisão. A EPR reuniu o maior número de atributos pessoais da resiliência dentre os instrumentos encontrados na revisão deste trabalho. A escala pode ser utilizada em novos estudos e será normatizada em futuro próximo.

Evaluating zero error noise thresholds by replica method for Gallager code ensembles

The replica method, developed in statistical physics, is employed in conjunction with Gallager's methodology to accurately evaluate zero error noise thresholds for Gallager code ensembles. Our approach generally provides more optimistic evaluations than those reported in the information theory literature for sparse matrices; the difference vanishes as the parity check matrix becomes dense.

Retrospective reports of child feeding practices, current eating behaviors, and BMI in college students

Research concerning child feeding practices has focused on children and adolescents, and little is known about how feeding practices used in childhood relate to eating behaviors and weight status in early adulthood. We assessed college students' and their parents' retrospective reports of child feeding practices used when the students were in middle childhood. We also assessed the college students' current reports of their eating behaviors using the Dutch Eating Behavior Questionnaire (DEBQ) and the Intuitive Eating Scale (IES), and measured their current BMI. Results showed that college students' and their parents' reports about previous parental use of child feeding practices were not correlated. Parent reports of their own use of child feeding practices were more related to students' eating behaviors and BMI than were students' recollections about feeding practices used by their parents. An analysis of gender effects showed that there were positive correlations between parental child feeding practices, BMI, and emotional eating for female students. These relationships did not exist for male students. The results suggest that child feeding practices recollected by parents are linked to the development of emotional eating and weight status of women in early adulthood.

Mechanical properties and the evolution of matrix molecules in PTFE upon irradiation with MeV alpha particles

The morphology, chemical composition, and mechanical properties in the surface region of α-irradiated polytetrafluoroethylene (PTFE) have been examined and compared to unirradiated specimens. Samples were irradiated with 5.5 MeV 4He2+ ions from a tandem accelerator to doses between 1 × 106 and 5 × 1010 Rad. Static time-of-flight secondary ion mass spectrometry (ToF-SIMS), using a 20 keV C60+ source, was employed to probe chemical changes as a function of a dose. Chemical images and high resolution spectra were collected and analyzed to reveal the effects of a particle radiation on the chemical structure. Residual gas analysis (RGA) was utilized to monitor the evolution of volatile species during vacuum irradiation of the samples. Scanning electron microscopy (SEM) was used to observe the morphological variation of samples with increasing a particle dose, and nanoindentation was engaged to determine the hardness and elastic modulus as a function of a dose. The data show that PTFE nominally retains its innate chemical structure and morphology at a doses <109 Rad. At α doses ≥109 Rad the polymer matrix experiences increased chemical degradation and morphological roughening which are accompanied by increased hardness and declining elasticity. At  α doses >1010 Rad the polymer matrix suffers severe chemical degradation and material loss. Chemical degradation is observed in ToF-SIMS by detection of ions that are indicative of fragmentation, unsaturation, and functionalization of molecules in the PTFE matrix. The mass spectra also expose the subtle trends of crosslinking within the α-irradiated polymer matrix. ToF-SIMS images support the assertion that chemical degradation is the result of a particle irradiation and show morphological roughening of the sample with increased a dose. High resolution SEM images more clearly illustrate the morphological roughening and the mass loss that accompanies high doses of a particles. RGA confirms the supposition that the outcome of chemical degradation in the PTFE matrix with continuing irradiation is evolution of volatile species resulting in morphological roughening and mass loss. Finally, we reveal and discuss relationships between chemical structure and mechanical properties such as hardness and elastic modulus.

Microwave photonic filtering using Gaussian-profiled superstructured fibre Bragg grating and dispersive fibre

Microwave photonic filtering is realised using a superstructured fibre Bragg grating. The time delay of the optical taps is precisely controlled by the grating characteristics and fibre dispersion. A bandpass response with a rejection level of >45 dB is achieved.

Alkuegyensúlyok és stabil halmazok

A játékelmélet egy fontos kutatási területe a Nash-program, amely a kooperatív és nemkooperatív megoldáskoncepciók között próbál kapcsolatot teremteni. Dolgozatomban az egyik első kooperatív megoldást vizsgálom, a stabil halmazokat. Harsányi egy 1974-ben megjelent cikkében foglalkozott a témával, megfogalmazta a nehézségeket a stabil halmazok nemkooperatív játékokba ültetésével kapcsolatban, valamint megadta a játékok egy olyan részhalmazát, ahol ez probléma nem áll fenn. Ezen az osztályon a stabil halmazok előállnak úgy, mint egy nemkooperatív alkujáték egyensúlyi stratégiáinak fixpontjai. Ezt az alkujátékot változtatom meg, és megmutatom, hogy így már a hozzárendelési játékok (amelyek csak nagyon speciális esetben voltak a Harsányi-féle osztályban) stabil halmazai is előállnak egyensúlyként.

Market Characteristics in Economy/Budget Lodging

With so many economy/budget lodging brands and rooms added to the market, it is difficult for consumers to identify differences in the services offered. In addition, industry practitioners need to understand what is expected of them by the consumers they serve. The authors review the economy budget lodging in general and empirically examine this issue.

Determining polarization dependent diffraction coefficients from building edges using FDTD method

Electromagnetic waves in suburban environment encounter multiple obstructions that shadow the signal. These waves are scattered and random in polarization. They take multiple paths that add as vectors at the portable device. Buildings have vertical and horizontal edges. Diffraction from edges has polarization dependent characteristics. In practical case, a signal transmitted from a vertically polarized high antenna will result in a significant fraction of total power in the horizontal polarization at the street level. Signal reception can be improved whenever there is a probability of receiving the signal in at least two independent ways or branches. The Finite-Difference Time-Domain (FDTD) method was applied to obtain the two and three-dimensional dyadic diffraction coefficients (soft and hard) of right-angle perfect electric conductor (PEC) wedges illuminated by a plane wave. The FDTD results were in good agreement with the asymptotic solutions obtained using Uniform Theory of Diffraction (UTD). Further, a material wedge replaced the PEC wedge and the dyadic diffraction coefficient for the same was obtained.

KOSMOS Finland 2012 mesocosm study: primary production and respiration

Anthropogenic carbon dioxide (CO2) emissions are reducing the pH in the world's oceans. The plankton community is a key component driving biogeochemical fluxes, and the effect of increased CO2 on plankton is critical for understanding the ramifications of ocean acidification on global carbon fluxes. We determined the plankton community composition and measured primary production, respiration rates and carbon export (defined here as carbon sinking out of a shallow, coastal area) during an ocean acidification experiment. Mesocosms (~ 55 m3) were set up in the Baltic Sea with a gradient of CO2 levels initially ranging from ambient (~ 240 µatm), used as control, to high CO2 (up to ~ 1330 µatm). The phytoplankton community was dominated by dinoflagellates, diatoms, cyanobacteria and chlorophytes, and the zooplankton community by protozoans, heterotrophic dinoflagellates and cladocerans. The plankton community composition was relatively homogenous between treatments. Community respiration rates were lower at high CO2 levels. The carbon-normalized respiration was approximately 40 % lower in the high CO2 environment compared with the controls during the latter phase of the experiment. We did not, however, detect any effect of increased CO2 on primary production. This could be due to measurement uncertainty, as the measured total particular carbon (TPC) and combined results presented in this special issue suggest that the reduced respiration rate translated into higher net carbon fixation. The percent carbon derived from microscopy counts (both phyto- and zooplankton), of the measured total particular carbon (TPC) decreased from ~ 26 % at t0 to ~ 8 % at t31, probably driven by a shift towards smaller plankton (< 4 µm) not enumerated by microscopy. Our results suggest that reduced respiration lead to increased net carbon fixation at high CO2. However, the increased primary production did not translate into increased carbon export, and did consequently not work as a negative feedback mechanism for increasing atmospheric CO2 concentration.
