BACKGROUND Previous research indicates that individuals with seasonal depression (SD) do not exhibit the memory biases for negative self-referent information that characterize non-seasonal depression (NSD). The current study extended this work by examining processing of self-referent emotional information concerning potential future events in SD. METHOD SD and NSD patients, along with never-d...

To determine the associations of fecundity and childlessness with month of conception and to find a causal mechanism for these associations, we reanalyzed some of our previous data according to the predictions of the seasonal optimal ripening oocyte (SOptRO) and seasonal preovulatory over-ripeness ovopathy (SPrOO) hypotheses. Prime and minor SOptRO months as well as high-risk, no-risk, and very...

BACKGROUND In animals, the circadian pacemaker regulates seasonal changes in behavior by transmitting a signal of day length to other sites in the organism. The signal is expressed reciprocally in the duration of nocturnal melatonin secretion, which is longer in winter than in summer. We investigated whether such a signal could mediate the effects of change of season on patients with seasonal a...

For close to 70 years, the Natural Resources Conservation Service (NRCS) has provided seasonal water supply outlooks for use by Western US water managers. These outlooks are a critical component in effective water management and are utilized by a broad spectrum of users for a variety of purposes, ranging from irrigated agriculture, flood control, municipal water supply, endangered species prote...

11 Shell fluxes of planktonic foraminifera species vary intra-annually in a pattern that appears to 12 follow the seasonal cycle. However, the variation in the timing and prominence of seasonal 13 flux maxima in space and among species remain poorly constrained. Thus, although 14 changing seasonality may result in a flux-weighted temperature offset of more than 5°C 15 within a species, this eff...

BACKGROUND Seasonal variation affects food availability. However, it is not clear if it affects dietary intake and nutritional status of children in Vietnam. OBJECTIVES This paper aims at examining the seasonal variation in nutrition status and dietary intake of children aged 24-59 months. DESIGN A repeated cross-sectional study design was used to collect data of changes in nutritional stat...

The European Space Agency has acquired 10 years of data on the temporal and spatial distribution of phytoplankton biomass from the MEdium Resolution Imaging Spectrometer (MERIS) sensor for ocean color. The phytoplankton biomass was estimated with the MERIS product Algal Pigment Index 1 (API 1). Seasonal-Trend decomposition of time series based on Loess (STL) identified the temporal variability ...

In southern Tibet, ongoing vertical and horizontal motions due to the collision between India and Eurasia are monitored by large numbers of global positioning system (GPS) continuous and campaign sites installed in the past decade. Displacements measured by GPS usually include tectonic deformation as well as non-tectonic, time-dependent signals. To estimate the regional long-term tectonic defor...

BACKGROUND Birth weight is known to fluctuate with season of birth, however, there is little information about seasonal variation in neonatal anthropometric measures. AIMS The aim of this study was to examine seasonal fluctuations in birth weight and selected anthropometric measures. STUDY DESIGN AND SUBJECTS The birth weight of singletons born after at least 37 weeks gestation was extracte...
