The authors develop and validate multidimensional and contextual profiles of competence among low-income, urban, middle adolescents (N = 560). The assessment of contextual competence was based on youth self-reports of involvement, performance, and relationship quality in the peer, school, athletic, employment, religious, and cultural contexts. A principal components analysis of these engagement indices revealed the six expected components with the addition of a component labeled self-in-context. To identify holistic, multidimensional profiles of contextual competence, scores along the seven domains were cluster analyzed. Nine clusters emerged, each representing a distinct constellation of youth experience. Profiles were associated with demographic variables and youth adjustment. Profiles reflecting high engagement in two or more contexts predicted higher self-esteem and lower depression. In contrast, profiles marked by high engagement in the contexts of athletics or employment predicted more serious delinquency. The authors discuss the implications of these findings for future research and intervention.  相似文献

Online impulse shopping is a growing industry. This paper uses the Stimulus-Organism-Response framework to model online impulse purchase behavior using a novel combination of stimuli and organism characteristics. The stimuli: social proof, limited-quantity scarcity, and high-demand, are three commonly used website features known as dark patterns. The organism characteristic personality is measured by the big 5 personality traits and persona generated through latent profile analysis. Using the machine learning algorithm XGBoost, impulse purchasing response was predicted separately for each dark pattern stimuli. Results show personality characteristics are important features when predicting consumer impulse purchasing in response to dark pattern messages. Moreover, the personality traits (and personas) most predictive of impulse shopping behavior varied by type of dark pattern. Findings suggest personality influences susceptibility to different dark patterns, indicating a need for tailored interventions to mitigate individual consumer vulnerabilities to impulse shopping.  相似文献

This paper examines degree of traumatisation, defence styles, coping strategies, symptomatology, and social support in a small sample of HIV-positive men and women in an effort to ascertain the psychological implications of living with Human Immunodeficiency Virus (HIV). Traumatisation and the potentially mediating effects of defence styles have only been the subject of a few studies of HIV positives. The study is based on a socio-demographic questionnaire, the Impact of Event Scale, the Defence Style Questionnaire, the Coping Styles Questionnaire, the Trauma Symptom Checklist, and the Crisis Support Scale. A degree of traumatisation that warrants treatment was found together with an association between particular coping strategies and symptomatology, and particular defence styles and symptomatology, respectively. Social support had increased over time, which is contrary to other research findings on social support.  相似文献

Home observations of mother-father-infant interaction and mother-infant interaction were contrasted in middle-class families in which the mother was employed or a full-time caregiver. First-born infants and their parents were observed at 3 months. The results indicate that when mother, father, and infant were together parents in the single wage-earner families provided more tactile stimulation to their babies; fathers in single wage-earner families tended to interact more with their infants than did mothers, while in dual wage-earner families mothers tended to interact more than fathers; and fathers in single wage-earner families exceeded fathers in dual wage-earner families in interactions with their infants. By contrast, mothers in the two groups showed very little difference in their interactions with their babies. No significant differences were found for maternal behavior in the three-person observation, and a single behavior differentiated between the groups in the mother-baby observation, with homemaker mothers more often making visual contact with their babies. The implications of these findings are discussed, both with respect to further research, and with regards to the development of children of employed mothers.  相似文献

What happens to education when the potential it helps realizing in the individual works against the formal purposes of the curriculum? What happens when education becomes a vehicle for its own subversion? As a subject-forming state apparatus working on ideological speciesism, formal education is engaged in both human and animal stratification in service of the capitalist knowledge economy. This seemingly stable condition is however insecured by the animal rights activist as undercover learner and??worker, who enters education and research laboratories under false premises in order to extract the knowledge necessary to dismantle the logic of animal utility on which the scientific-educational apparatus rests. The present article is based on a semi-structured interview with an undercover worker. It draws on a synthesis of critical education and posthumanist theories to configure knowledge creation and subjectification processes in the ??negative spaces?? of education. The techne of undercover work includes mnemotechnical and prosthetic devices, calculation of risk, and mimetic labor. The article argues that the agenda of the undercover worker generates a multi-strained mimetic complex that composes a parasitic educational subject-assemblage redirecting scientific knowledge away from the animal stratification logic of the knowledge economy into different viral circuits; different lines of flight. It invites a rearticulation of the formal education state apparatus in more indeterminate directions, provoking scientific-educational knowledge-practices to become a catalytic impulse for their own disintegration.  相似文献
