Egg arrangement in avian clutches covaries with the rejection of foreign eggs

In birds, the colour, maculation, shape, and size of their eggs play critical roles in discrimination of foreign eggs in the clutch. So far, however, no study has examined the role of egg arrangement within a clutch on host rejection responses. We predicted that individual females which maintain consistent egg arrangements within their clutch would be better able to detect and reject foreign eggs than females without a consistent egg arrangement (i.e. whose eggs change positions more often across incubation). We tested this “egg arrangement hypothesis” in blackbirds (Turdus merula) and song thrush (T. philomelos). Both species are suitable candidates for research on egg rejection, because they show high inter-individual variation and individual repeatability in egg rejection responses. As predicted, using our custom-defined metrics of egg arrangement, rejecter females’ clutches showed significantly more consistent patterns in egg arrangement than acceptor females’ clutches. Only parameters related to blunt pole showed consistent differences between rejecters and acceptors. This finding makes biological sense because it is already known that song thrush use blunt pole cues to reject foreign eggs. We propose that a disturbance of the original egg arrangement pattern by the laying parasite may alert host females that maintain a consistent egg arrangement to the risk of having been parasitized. Once alerted, these hosts may shift their discrimination thresholds to be more restrictive so as to reject a foreign egg with higher probability. Future studies will benefit from experimentally testing whether these two and other parasitized rejecter host species may rely on the use of consistent egg arrangements as a component of their anti-parasitic defence mechanisms.     

An Analysis of a Cross-Cultural Personality Inventory: The IPIP Big-Five Factor Markers in Croatia

We investigated the psychometric properties of the Oregon Vocational Interest Scales (ORVIS), a brief public-domain alternative to commercial inventories, in a large community sample and in a college sample. In both samples, we examined the factor structure, scale intercorrelations, and personality correlates of the ORVIS, and in the community sample, we also examined the correlations of the ORVIS scales with cognitive abilities and with the scales of a longer, proprietary interest survey. In both samples, all 8 scales—Leadership, Organization, Altruism, Creativity, Analysis, Producing, Adventuring, and Erudition—showed wide variation in scores, high internal-consistency reliabilities, and a pattern of high convergent and low discriminant correlations with the scales of the proprietary interest survey. Overall, the results support the construct validity of the scales, which are recommended for use in research on vocational interests and other individual differences.     

How challenging was your work today? The role of autonomous work motivation

The main aim of this study was to investigate whether autonomous motivation for work can explain the distinctive associations between hindrance and challenge demands and work-related well-being (i.e., positive affect and work engagement) on a within-person level. Autonomous work motivation represents the degree to which motivation for putting effort in work is intrinsic (i.e., with a sense of volition and personal choice) or has been internalized (i.e., without feelings of internal or external pressure). In order to test our hypotheses, we employed a diary methodology and followed 153 secondary school teachers throughout five consecutive working days. The results of multilevel modelling provided support for the hypothesized research model. On days when teachers experienced more challenges, they also experienced more positive affect and more engagement in their work on the same day, and this relationship could be explained by (higher) autonomous work motivation on that day. In contrast, on days when teachers experienced more hindrance demands, they experienced less positive affect and less work engagement, and this process was explained by (reduced) autonomous work motivation that day. Our findings add to the literature by showing that daily autonomous motivation as a motivational process can explain why daily challenge and hindrance demands are differentially related to positive well-being at work.     

Emotional Detachment of Partners and the Sanctity of the Relationship with the Analyst as the Most Powerful Curative Factor

The relationship between partners and the analyst is considered the most basic means for healing in contemporary psychoanalytic theories and analyses. It also holds as one of the most fundamental phenomenon’s of psychoanalysis, so it comes as no surprise that it has always been deliberated over as an object of great interest as well as immense controversy. This same relationship, mutually co-created by the analyst and each individual and partner in analysis, represents also the core of sanctity and sacred space in contemporary psychoanalysis.     

Metacognitive Habits: Contradiction in Terms or Valid Theoretical Concept? The Role of Metacognition in Habitual Behavior

The aim of the present article is to present data showing that habitual actions might be conceptualized as metacognitive habits. The study is based on 3 data collections assessing smoking and school attendance. Habits were measured by a self-report habit index (SRHI) scale that assesses the level in which given behaviors are performed without self-awareness. Metacognitions were measured by the Mental Constructions (MCs) scale that assesses the level of awareness in performing behaviors in question. The results show that MCs and SRHI have (a) moderate to strong positive correlations and (b) similar relations to dependent variables. The study concludes that the further explorations of metacognitive habits are warranted.     

How people see others is different from how people see themselves: a replicable pattern across cultures

Consensus studies from 4 cultures--in Belgium, the Czech Republic, Estonia, and Germany--as well as secondary analyses of self- and observer-reported Revised NEO Personality Inventory (NEO PI-R) data from 29 cultures suggest that there is a cross-culturally replicable pattern of difference between internal and external perspectives for the Big Five personality traits. People see themselves as more neurotic and open to experience compared to how they are seen by other people. External observers generally hold a higher opinion of an individual's conscientiousness than he or she does about him- or herself. As a rule, people think that they have more positive emotions and excitement seeking but much less assertiveness than it seems from the vantage point of an external observer. This cross-culturally replicable disparity between internal and external perspectives was not consistent with predictions based on the actor-observer hypothesis because the size of the disparity was unrelated to the visibility of personality traits. A relatively strong negative correlation (r = -.53) between the average self-minus-observer profile and social desirability ratings suggests that people in most studied cultures view themselves less favorably than they are perceived by others.     

A Categorical Approach to Probability Theory

First, we discuss basic probability notions from the viewpoint of category theory. Our approach is based on the following four “sine quibus non” conditions: 1. (elementary) category theory is efficient (and suffices); 2. random variables, observables, probability measures, and states are morphisms; 3. classical probability theory and fuzzy probability theory in the sense of S. Gudder and S. Bugajski are special cases of a more general model; 4. a good model allows natural modifications. Second, we show that the category ID of D-posets of fuzzy sets and sequentially continuous D-homomorphisms allows to characterize the passage from classical to fuzzy events as the minimal generalization having nontrivial quantum character: a degenerated state can be transported to a nondegenerated one. Third, we describe a general model of probability theory based on the category ID so that the classical and fuzzy probability theories become special cases and the model allows natural modifications. Finally, we present a modification in which the closed unit interval [0,1] as the domain of traditional states is replaced by a suitable simplex.     

Is intrinsic religious orientation a culturally specific American Protestant concept? The fusion of intrinsic and extrinsic religious orientation among non‐Protestants

The relationship between intrinsic and personal extrinsic religious orientation as suggested by Gorsuch and McPherson is studied within four denominational samples of university students in four different cultural environments. Results show that intrinsic and extrinsic personal religious orientation form two separate dimensions only within the American Protestant sample. In three different European religious environments (one Eastern Orthodox, one Islamic, and one Roman Catholic), all extrinsic personal and intrinsic items can be combined into a single dimension. It is speculated that the intrinsic orientation may be culturally tied to Protestantism. Copyright © 2007 John Wiley & Sons, Ltd.     

Authority-based Argumentative Strategies: A Model for their Evaluation

In this paper, I try to develop an informal model for the analysis and evaluation of argumentative strategies based on active authorities. The explanations necessary to understand the idea of the model and what is modelled are given through the development of the paper. I first give an example of argumentative activities. After that, the main assumption of the model is given. In the third part, the relevant aspects of the argumentative activity are analysed, while the principles of the evaluation are explained in the fourth part. The informal model is presented in the fifth part. In the final remarks, the suggestions for further work are given, as well as a comparison with some related recent works in argumentation theory.
