We investigated whether female zebra finches (Taeniopygia guttata) would alter their mate preferences after observing the choices of other females. Experimental trials consisted of four 30-min stages: (A) acclimation, (B) observer female chooses between two males, (C) observer female watches a model female interact with her nonpreferred male from stage B, and (D) observer female again chooses between the two males. Control trials were identical except that there was no model female in stage C. Females in both experimental and control trials spent significantly more time with the nonpreferred male in stage D than they had in stage B; thus, our experiment appeared to reveal no evidence of mate choice copying. There was, however, a significant positive relationship between the increase in the time that an observer female in experimental trials spent with her nonpreferred male in stage D and the number of interactions that she had previously observed between the model female and that male in stage C. A second experiment of similar design, where observer females were prevented from observing the model female and nonpreferred male interact in stage B, demonstrated that the behaviour of the observer female in the first experiment was not simply a response to changes in male behaviour in stage D. While our experiment does not support the hypothesis that female zebra finches copy each other's mate preferences, our findings suggest that public information may influence the behaviour of female zebra finches toward potential mates.

Social learning enables adaptive information acquisition provided that it is not random but selective. To understand species typical decision-making and to trace the evolutionary origins of social learning, the heuristics social learners use need to be identified. Here, we experimentally tested the nature of majority influence in the zebra finch. Subjects simultaneously observed two demonstrator groups differing in relative and absolute numbers (ratios 1 : 2/2 : 4/3 : 3/1 : 5) foraging from two novel food sources (black and white feeders). We find that demonstrator groups influenced observers' feeder choices (social learning), but that zebra finches did not copy the majority of individuals. Instead, observers were influenced by the foraging activity (pecks) of the demonstrators and in an anti-conformist fashion. These results indicate that zebra finches are not conformist, but are public information users.

Love is more than a close friendship. It acts as a major facilitator of interpersonal relationship. Love is positive in nature and leaves a positive affect on every individual. An individual in love not only feels positive but spreads positivity around. They smile, be kind to other people, behave compassionately with everyone. If the person is happy then he is likely to be psychologically and emotionally healthy. The current study aimed at understanding the relationship between love, affect and wellbeing among young females aged between 20-25 years. The study reported a significant positive relationship between love and positive affect with the significant correlation of 0.29 at 0.05 levels (p<0.05). It was also found a significant positive relationship between love and wellbeing with the significant correlation of 0.58 at 0.01 level (p<0.01). This means that people in love experience positive emotions and healthy wellbeing. The correlation between love and negative affect came out to be insignificant. The correlation turned out to be -0.13. This means that people in love do not experience negative emotions.

The 2 types of exchange relationship perceptions—social exchange relationship perceptions (SERPs) and economic exchange relationship perceptions (EERPs)—constitute the primary concept for understanding individual behavior in the workplace. Using a sample of 581 employees from Mainland China, I explored the effects of SERPs and EERPs on employee extrarole behavior (ERB), as well as the moderating effect of organization-based self-esteem (OBSE) on the relationships between SERPs and ERB, and between EERPs and ERB. The results revealed a significant positive relationship between SERPs and ERB, a significant negative relationship between EERPs and ERB, and a significant moderating effect for OBSE. Theoretical and practical implications of these findings are discussed.

Abstract In this research on the one hand we analyzed the relationship that exists in terms of motivational persistence and the Big Five dimensions and, on the other hand, organizational citizenship behavior (OCB). The results show that the conscientiousness has been identified as being in a significant positive relationship with OCB. This result is consistent with the data provided by previous researchers. The results also indicate that three conscientiousness facets are in a positive relationship with OCB. These three conscientiousness facets are self-efficacy, cautiousness and orderliness. Agreeableness was not identified as being associated with OCB. At the level of the relationship between motivational persistence factors and OCB, we have identified a significant positive relationship with only one factor: current purpose pursuing. The OCB model has two variables that work best as predictors: high scores with regard to current purpose in terms of the pursuing-motivational persistence factor, and low scores in terms of the imagination-facet of openness to experience.

Total dissolved solids (TDS) and chlorophyll a were not related in 25 lakes which were all off the Precambrian Shield. Both on-shield and off-shield lakes were included in the previous reports which showed a significant relationship between TDS and productivity. When data from on-shield and off-shield lakes were analyzed separately, there was no significant positive relationship between TDS and lake biomass or productivity. It was also shown that mean depth ([Formula: see text]) was as good a predictor of fish production as the TDS: [Formula: see text] ratio, the morphoedaphic index.Key words: TDS, biomass, productivity, morphoedaphic index, chlorophyll a, lakes
