Engineering students’ perceptions of engineering specialties

The field of engineering is defined by a number of specialty areas, thus most engineering students must decide upon an educational specialty track within the engineering major. Data on familiarity with, and perceptions of similarity among 11 engineering specialties were collected from 129 undergraduate engineering students from a public urban university. Similarity data were collected by way of a paired comparison task, and multidimensional scaling techniques were used to map these data into spatial representations. A three-dimensional solution was selected. Analysis of variance procedures also were used to examine differences in perceptions of engineering specialties by gender, ethnicity, commitment to career choice, and career decision-making self-efficacy. Results indicated that female students rated engineering specialties as more prestigious than male students, and students with a more dogmatic stance towards career rated engineering as relatively exclusive to men.     

Stability of interests across ethnicity and gender: A longitudinal examination of grades 8 through 12

RIASEC interests were assessed in grades 8, 10, and 12 on a large national sample of 69,987 college bound students. Random samples of 1000 were drawn to represent each of the major US ethnic groups (African, Asian, Native, Mexican, Latino (non Mexican), Anglo, and Multiracial Americans) and interests were examined as they varied across time, ethnicity, and gender with respect to structure, mean changes, stability, clarity, and interest-occupational choice congruence. Results indicate that the structure of interests did not vary as a function of time, gender or ethnicity. The pattern of interests was fairly stable and similar across all ethnic groups and both genders. Congruence and clarity increased in 10th grade but both decreased in 12th grade suggesting a time of re-examination.     

Permanent Housing for Child Welfare‐Involved Families: Impact on Child Maltreatment Overview

A longitudinal randomized controlled trial tested whether access to permanent housing reduces child maltreatment among inadequately housed families under investigation for child abuse and neglect. The study followed homeless and child welfare‐involved families randomly assigned to receive a referral for housing subsidies plus housing case management (n = 75, 196 children) or housing case management alone (n = 75, 186 children). Latent growth models examined change in caregiver‐reported frequencies of psychological aggression, physical abuse, and neglect toward children at five time points across 2.5 years. Intent‐to‐treat analyses suggested treatment differences for minor assault and neglect that approached significance; families randomly assigned to permanent housing plus case management exhibited marginally greater declines compared to families referred for housing case management only. Caregiver psychological aggression remained high over time, regardless of treatment condition. No evidence indicated higher risk families benefitted more from permanent housing. Results show some promise of permanent housing and highlight the complex needs of homeless families under investigation for child maltreatment. Findings emphasize the importance of continued involvement from the child welfare system to connect families with important resources.     

Behavioral landscapes and earth mover’s distance: A new approach for studying individual differences in density distributions

Contemporary views of personality highlight intraindividual variability. We forward a general method for quantifying individual differences in behavioral tendencies based on Earth Mover’s Distance. Using data from 150 individuals who reported on their and others’ interpersonal behavior in 64,112 social interactions, we illustrate how this new approach can advance notions of personality as density distributions. Results provide independent confirmation and establish validity of existing representations of individual differences in interpersonal behavior, and identify new dimensions and profiles of personality and well-being. Benefits of the EMD method include freedom from assumptions about the shape and form of density distributions, generality of application to n-dimensional behavior captured in experience sampling studies, and natural integration of personality structure and dynamics.     

Bidirectional pathways between relational aggression and temperament from late childhood to adolescence

Relational aggression is linked to numerous adverse consequences. However, we know little about how temperament leads individuals to become perpetrators/victims of relational aggression, or how being a perpetrator/victim influences the development of temperament. We used longitudinal data from 674 Mexican-origin youth to examine relations between relational aggression and mother- and child-reported temperament from 5th grade (M_age = 10.8; SD = 0.60) through 11th grade (M_age = 16.8; SD = 0.50). Results show that: (a) high Negative Emotionality and low Effortful Control predicted increases in victimization; (b) low Effortful Control predicted increases in perpetration; (c) victims increased in Negative Emotionality and decreased in Effortful Control; and (d) perpetrators increased in Negative Emotionality and Surgency. Thus, temperament serves as both an antecedent to and a consequence of relational aggression.     

心理测量学模型在学习进阶中的应用:理论、途径和突破

学习进阶是对学生在一段时间内,关于某一主题连续发展、逐渐复杂思维的描述,它的建立是以假设性学习进阶为起点到收集证据验证假设性学习进阶不断迭代的过程。心理测量学模型能够使学习进阶与评价结合起来,既为验证学习进阶的有效性提供证据,又能对学生做出诊断,当前应用到学习进阶中的心理测量学模型有单维项目反应模型、多维项目反应模型和认知诊断模型。学习进阶还能为垂直量尺化、自适应学习提供新的研究视角,但应注意项目功能差异等问题。     

Do Early Difficult Temperament and Harsh Parenting Differentially Predict Reactive and Proactive Aggression?

The goal of this study was to examine the links between difficult temperament (i.e., negative emotionality) and harsh parental discipline during toddlerhood, and reactive and proactive aggression in kindergarten. These links were assessed on a longitudinal population-based study of 1516 boys and girls followed longitudinally from the age of 17 months through the age of 72 months. Two possible models were tested to examine the interplay between negative emotionality and harsh parenting in predicting later reactive aggression compared to proactive aggression. The first was an additive model where both aspects make unique contributions in predicting later reactive aggression. The second model was an interactive model where harsh parenting exacerbates the link between negative emotionality and reactive aggression. Results showed a specific contribution of negative emotionality to reactive aggression. The results relative to harsh parenting are more mixed but nonetheless in line with developmental models stressing different pathways to reactive and proactive aggression.     

Effects of iron deficiency in infancy on patterns of motor development over time

This longitudinal study of the effects of iron deficiency in infancy assessed motor development over time in 185 healthy Costa Rican children who varied in iron status at 12-23 months. Longitudinal analyses (hierarchical linear modeling) used the Bayley Psychomotor Index before and both 1 week and 3 months after iron treatment in infancy and the Bruninks-Oseretsky Test of Motor Proficiency - long form at 5 years and short form at 11-14 years. Children with chronic severe iron deficiency in infancy had lower motor scores at the beginning of the study and a lower but parallel trajectory for motor scores through early adolescence. Thus, there was no evidence of catch-up in motor development, despite iron therapy in infancy that corrected iron deficiency anemia in all cases.     

A longitudinal investigation of the role of perceived autonomy support from coaches in reducing athletes’ experiential avoidance: The mediating role of subjective vitality

Experiential avoidance, a personality trait that refers to individuals’ tendency to avoid negative experiences, can have a negative impact on athletes’ goal achievement. For this reason, it is crucial to identify the factors that can mitigate such a tendency. Drawing on self-determination theory and referring specifically to the function of subjective vitality, we first hypothesize that perceived autonomy support from coaches is positively associated with athletes’ subjective vitality, which in turn is negatively associated with athletes’ experiential avoidance. Data were collected from one hundred eighty-five high school athletes in Taiwan using a three-wave, time-lagged survey design spanning a period of seven months. These athletes were drawn from ten senior high schools and were in their second year of high school. The results of regression analysis showed that perceived autonomy support from coaches at Time 1 was associated with higher vitality among athletes at Time 2, which was, in turn, associated with lower levels of experiential avoidance at Time 3, conditional on the athletes’ experiential avoidance at Time 2. While perceived autonomy support from coaches at Time 1 was also associated with lower experiential avoidance at Time 2, experiential avoidance at Time 2 was not associated with vitality at Time 3 after controlling for vitality at Time 2. The results of mediation analysis further supported the claim that vitality is a critical mediator of the relationship between perceived autonomy support from coaches and athletes’ experiential avoidance. Implications concerning the identification of this mediator are discussed.
