Changes in follicular size (in diameter) were studied by laparotomy under various photoperiodic regimes in the domesticated ring doves that have been kept under standard laboratory conditions for generations. Follicular response shows two distinct patterns: 1. a shift from standard laboratory photoperiodic regime (LD 14:10) to extra long day (LD 20:4) accelerated the follicular development in the spring as well as in the autumn; 2. a shift from the standard laboratory photoperiodic regime (LD 14:10) to short day (LD 8:16 or LD 1/2:23 1/2) induced follicular regressions in the autumn but not in the spring. We propose that there is a responsive phase (spring) and nonresponsive phase (autumn) of hypothalamo-hypophyseal-ovarian system in the ring doves. Comparison of radioimmunoassay of pituitary and plasma LH value suggests that the responsive and non-responsive phase involves mainly release mechanisms. In the autumn, the release mechanism becomes insensitive to stimuli below certain thresholds. Our ring doves are kept in responsive phase throughout the year under the long photoperiodicity (LD 14:10). However, the effect of long day does not appear to override completely the seasonal effect.

A short introduction into Bayesian evaluation of informative hypotheses as an alternative to exploratory comparisons of multiple group means

in Tutorials in Quantitative Methods for Psychology (2012), 8

This paper presents an introduction into Bayesian evaluation of informative hypotheses, that is, hypotheses representing explicit expectations about multiple group means (Hoijtink, 2011; Hoijtink, Klugkist & Boelen, 2008). The authors begin by discussing some limits of exploratory methods before presenting a non-technical overview of the Bayesian approach. References are provided for the technical details. A particular effort is made to illustrate the method with an example from psychology. References to software, more elaborate textbooks and tutorials enable researchers to apply this novel method to their own data. [less ▲]

In this paper, a bibliographical review of current sustainable development indicators used at regional and global level is presented. This review was undertaken as part of an analysis on the status quo on how to measure sustainable development and the ways to quantify results regarding set goals. Its purpose is to establish if the results of the actions taken in order to achieve the targets of the Millennium Development Goals (MDG) and those that will be taken in order to reach the target of the Sustainable Development Goals (SDG).

A short Survey of Methods for Voltage Instability Detection

This paper shortly surveys existing and proposed methods for voltage instability detection. The emphasis is on methods relying on real-time measurements as well as on long-term voltage instability. Methods are classified according to the required measurement configuration: local vs. wide-area, standard SCADA-type vs. synchronized phasor measurements, etc. In the various categories, some of the features are summarized, and what appears to the authors as advantages or limitations is shortly discussed. An important feature is the ability to anticipate instability. Some tracks for further work on the subject are also outlined. [less ▲]

The short time-scale light variability of HD 153919 revisited

Using Fourier analysis techniques, the available sets of visual photometric data concerning the X-ray binary HD 153919 are analyzed in order to clear up the controversy on the possible existence or absence of the small-amplitude light variability (T = about 90 min). In this work, great effort has been made to keep a good level of homogeneity and objectivity. The main conclusion is that at the 99.4-percent confidence level, a periodicty (v = 15.5/day) is detected in one data set. In this case, it is possible to conclude that the short time-scale variability does exist. No other self-conclusive detection can be definitely reported; nevertheless, at the 90-percent confidence level, the star has a tendency to vary with characteristic frequencies of about 15/day, 30/day, and possibly higher multiples.
