Factor Structure and Construct Validity of the Youth Psychopathic Traits Inventory and Its Shorten Version in Chinese Detained Boys
2019
The Youth Psychopathic Traits Inventory (YPI) was designed to assess psychopathic traits in adolescents. However, there exists limited evidence for the factor structure and psychometric properties of the YPI when used with Chinese detained juveniles. The present study aimed to examine the factor structure and construct validity of the YPI and its shortened version (YPI-S) in a sample of 607 Chinese 14- to 22-year-old detained boys (M = 17.15, SD = 1.09). Confirmatory factor analyses revealed a bifactor model which best fit the data at the subscale level for the YPI, and at the item level for the YPI-S. The internal consistency of the YPI and YPI-S scores ranged from marginal to good. Both t…
School Bullying Through Graphic Vignettes : Developing a New Arts-Based Method to Study a Sensitive Topic
2020
The purpose of this study was to develop a new arts-based measure assessing school bullying and to test it within a pilot study involving 19 schoolchildren (mean age = 15.4; range = 1.00). The researchers designed the new methodological tool (referred to as graphic vignettes) as a set of incomplete comic strips, which participants were asked to complete in a creative way. Researchers then invited participants to engage in follow-up interviews using completed comic strips as individualized interview prompts. The authors detail the design and administration of the graphic vignettes and discuss their efficacy, limitations, and potential applications. The researchers argue that studies on sensi…
The ecological success of a social parasite increases with manipulation of collective host behaviour.
2015
Many parasites alter the behaviour of their host to their own advantage, yet hosts often vary in their susceptibility to manipulation. The ecological and evolutionary implications of such variation can be profound, as resistant host populations may suffer lower parasite pressures than those susceptible to manipulation. To test this prediction, we assessed parasite-induced aggressive behaviours across 16 populations of two Temnothorax ant species, many of which harbour the slavemaker ant Protomognathus americanus. This social parasite uses its Dufour's gland secretions to manipulate its hosts into attacking nestmates, which may deter defenders away from itself during invasion. We indeed find…
Aggression and violence among drivers
2001
The invention of assembly line manufacturing, together with the generalised and massive use of the private automobile, has transformed motor vehicles from simply being a mode of transportation to encompass and symbolise a new lifestyle and social order1. Unfortunately, as in many other facets of modern society, the driving environment is not exempt from the expression of violent behaviour2–3. Because the root of driving is found in the lifestyle of a society, this way of life not only dictates the use of motor vehicles but also the way in which they are used4.
The Story of Aggressive and Violent Peasant Elites in the North
2016
All over early modern Fennoscandia—in the areas of modern-day Norway, Sweden, and Finland—there were peasants who occupied wealthy farmsteads, held positions of trust, and had kinship networks with members of higher status groups such as local priests and state officials, burghers, and other gentry. Even though they served as a link between the rest of the peasantry and the state authorities, it is evident that early modern peasant resistance was also often led by the wealthy. There is abundant evidence in court records that these respected and leading members of the local community could practically terrorise their neighbourhood with violence and aggression. Why was there this seeming cont…
Aggression in television programs in Finland
1993
A detailed coding system was constructed to study the frequency and salience of aggression in TV programs broadcast on Finnish television. Salience of aggression was measured by the brutality index which consisted of ratings concerning the 1) program context, 2) seriousness, 3) justification, and 4) dramatization of aggressive acts. When compared to previous studies of TV-violence, the rate of aggression in Finnish TV was moderate with 3.5 aggressive acts per program hour. Only 14% of aggressive acts portrayed brutal aggression, which was mostly seen in fictional films and serials. A clear 9 pm watershed was not seen in Finland, since aggressive acts were distributed quite evenly during the…
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…
Gender discrimination in physics and astronomy: Graduate student experiences of sexism and gender microaggressions
2016
[This paper is part of the Focused Collection on Gender in Physics.] Sexism occurs when men are believed to be superior to women, and is thought to be one of the reasons for women’s underrepresentation in physics and astronomy. The issue of sexism in physics and astronomy has not been thoroughly explored in the physics education literature and there is currently no clear language for discussing sexism in the field. This article seeks to begin a conversation on sexism in physics and astronomy and offer a starting point for language to discuss sexism in research groups and departments. Interviews with 21 women in graduate physics and astronomy programs are analyzed for their individual experi…
Facing the Pandemic in Italy: Personality Profiles and Their Associations With Adaptive and Maladaptive Outcomes
2022
The negative impact of the COVID-19 pandemic on individuals’ psychosocial functioning was widely attested during the last year. However, the extent to which individual differences are associated with adaptive and maladaptive outcomes during quarantine in Italy remains largely unexplored. Using a person-oriented approach, the present study explored the association of personality profiles, based on three broad individual dispositions (i.e., positivity, irritability, and hostile rumination) and two self-efficacy beliefs in the emotional area (i.e., expressing positive emotions and regulating anger emotion), with adaptive and maladaptive outcomes during the first Italian lockdown (March–June 20…
Patterns of Boys' Social Adjustment in Two Cultures and at Different Ages: A Longitudinal Perspective
1992
In the comparison of two longitudinal studies, patterns of boys' social adjustment were identified by using aggression, hyperactivity, inattentiveness, anxiety, and lack of prosocial behaviour as clustering variables. Eight comparable clusters were obtained across two cultures, French Canada and Finland; three age groups, 6, 8, and 10 years; and two decades, the 1960s and 1980s. The clusters confirmed three frequently used categories of behaviour: (1) normal (for no adjustment problems); (2) anxious; and (3) inattentive; two infrequently used categories: (1) passive; and (2) nervous; and the importance of subcategorising aggressive-hyperactive boys into three categories: (1) bully; (2) unc…
