The Bias of combining variables on fish's aggressive behavior studies.
2019

No. of bitstreams: 0 Previous issue date: 2019-07-01 Quantifying animal aggressive behavior by behavioral units, either displays or attacks, is a common practice in animal behavior studies. However, this practice can generate a bias in data analysis, especially when the variables have different temporal patterns. This study aims to use Bayesian Hierarchical Linear Models (B-HLMs) to analyze the feasibility of pooling the aggressive behavior variables of four cichlids species. Additionally, this paper discusses the feasibility of combining variables by examining the usage of different sample sizes and family distributions to aggressive …
A brief review about anxiety and aggressive behavior in pediatric age
2018
Anxiety can be considered a normal experience of the human being and as such also of the child. It manifests itself in different ways according to the level of development: in the smaller the child, the more anxiety is expressed with manifestations that involve the whole organism, becoming evident either with motor excitement or with physical discomfort. As the psychic apparatus is structured, anxiety is experienced as an inner phenomenon and is experienced as an unpleasant state. Fortunately, we are all a bit anxious, even if there are some people who are more, others less.
Sexism in adolescence: parenting styles, division of housework, prosocial behaviour and aggressive behaviour /Sexismo en la adolescencia: estilos de …
2017
AbstractThe aim of this study was to identify which factors were the best predictors of sexist attitudes. To achieve this aim, two groups of variables were analysed. The first group consisted of variables relating to parenting styles and the division of housework. The second group consisted of personal factors related to prosocial behaviour and physical and verbal aggression. The sample was made up of 732 adolescents aged 12–14 from Valencia (Spain). The analysis was conducted separately for boys and girls. Correlation analyses and multiple linear regression analyses were conducted on each subsample. The results show that the division of housework and parenting styles were related to sexist…
Cyberbullying aggressors among Spanish secondary education students: an exploratory study
2015
Purpose– This paper aims to explore the prevalence rate of adolescents engaging in aggressive behaviours towards their peers using the Internet and mobile phones, while examining the duration and intensity of this cyberbullying, and to analyse differences in cyberbullying behaviours based on gender and age (academic grades). Research on cyberbullying indicates that it is a global problem that is increasing dramatically among adolescents.Design/methodology/approach– The sample was composed of 1,415 Spanish adolescents of both sexes (760 boys and 655 girls) between 12 and 17 years old (M = 13.9 years old; SD = 1.4).Findings– The results indicated that the cyberbullying prevalence among adoles…
Response of captive seabass and seabream as behavioural indicator in aquaculture
2010
Welfare of cultivate fish at high-density represents an important concern for modern aquaculture. The behaviour of European seabass (Dicentrarchus labrax) and seabream (Sparus aurata) reared in cages was studied in a fish farm of northern Sardinia (Italy) in autumn 2006 to test whether captive condition had an effect on the movement patterns of these two species.Video images recorded before, during and after the manual feeding distribution allowed us to collect data on different behaviours of captive fish. Thus, behaviours indicating the position of fish in the water column, swimming direction and possible aggressive behaviours (aggression, direction change and collision) showed juveniles a…
