The Relationship between Adult Students' Instructional Technology Competency and Self-Directed Learning Ability in an Online Course

The main purpose of this research was to examine the relationship between adult students' self-directed learning (SDL) ability and instructional technology (IT) competency in an online course. The study also investigated motivation and learning strategies that the students used to learn IT. The research involved surveying 198 continuing education professionals who took online courses at a large Midwest state university. The results indicate a statistically significant positive correlation between SDL ability and IT competency in students with above average SDL ability. The results also indicate that motivation is an important factor for learning technology in an online course regardless of the students' SDL ability. Additionally, the results show that students with higher level of SDL ability are likely to exhibit higher level of self-efficacy for learning and performance, and higher level of effort regulation.     

Graphical and Numerical Methods for Detecting Influential Observations in Complex Bingham Data

We describe methods to detect influential observations in a sample of pre-shapes when the underlying distribution is assumed to be complex Bingham. One of these methods is based on Cook's distance, which is derived from the likelihood of the complex Bingham distribution. Other method is related to the tangent space, which is based on the local influence for the multivariate normal distribution. A method to detect outliers is also explained. The application of the methods is illustrated in both a real dataset and a simulated sample.

Politics of Sex Appeal in Advertising

This article is an ethnographic exploration of how gender ideologies were negotiated in the South Korea of the 2000s, in advertising texts and in advertising workplaces. Advertising has been criticized for reproducing gender stereotypes, and it is easy to assume that it is men within advertising agencies who are responsible for the objectifying and sexualizing portrayals of women. Yet behind some of the raciest South Korean advertising campaigns were ambitious women, who not only eagerly repeated the marketing adage that “sex sells” but also, provocatively, attempted to obliterate the lingering patriarchal norms and double sexual standards—with sexualized advertising. This article examines the politics of sex appeal in contemporary South Korean advertising by drawing on participant observation at an advertising agency, interviews, and public discourse analysis. Having situated the women's interventions within the cultural–historical context of South Korea, I, first, show how women's embrace of the sex-appeal aesthetic was a strategy to succeed in a male-dominated work environment and, second, detail how fighting gender discrimination with sex-appeal advertising was a profoundly contradictory project. I suggest that the politics of sex appeal in advertising was symptomatic of how women's struggles for equality were collapsing into neoliberal post-feminist sensibility.     

Inclusion as Social Practice: Views of Children with Autism

This study illuminates the social realities of inclusion of 16 high functioning children with autism (HFA) in public schools in the United States. The study suggests that the practice of inclusion rests primarily on unaffected schoolmates rather than teachers, who typically are occupied monitoring academic progress and disciplinary transgressions across a range of children. Utilizing ethnographic observations and video recordings of quotidian classroom and playground activities, the analysis elucidates how classmates employ a range of positive and negative inclusion practices that either integrate or distance autistic children. Ethnographic observations of the study population indicate that the children whose diagnosis was fully disclosed enjoyed more consistent social support in the classroom and on the school playground. The study further suggests that high functioning children with autism exhibit a range of reactions to negative inclusion practices such as rejection and scorn. Such reactions include oblivion, immediate behavioral response, and emotionally charged accounts of disturbing school incidents shared after-the-fact with family members. Significantly, these observations indicate that HFA children can be cognizant of and distressed by others' derisive stances and acts, despite symptomatic difficulties in interpreting others' intentions and feelings.     

Infant Nutrition and 12 and 18 Months Secure Base Behavior: An Exploratory Study

A notable omission in studies of developmental links to early nutritional deficiencies is infant attachment. In those few studies investigating associations between infant nutrition and attachment, nutrition was defined solely by physical growth, and infants had moderate–severe growth retardation. In this study, we utilized multiple markers of infant nutrition. Our sample consisted of 172 12‐month‐old Peruvian infants and their mothers from low‐income families, with a follow‐up assessment on 77 infants at 18 months. Infants were not severely malnourished, but did have micronutrient deficiencies. Anthropometry, dietary intake, and iron status were used as measures of infant nutrition. Based on infant behavior in a structured laboratory situation, Q‐sort techniques were used to rate three attachment markers: infant secure base behavior, interaction quality, and negative emotionality with mother. At 12 months, infant weight was positively related to interaction quality. At 18 months, infant iron status was positively related to secure base behavior. This pattern of findings remained even after statistically controlling for family socioeconomic status and maternal education. Our findings indicate that infant nutritional status is associated with markers of infant attachment and these associations are not restricted just to severely malnourished infants.
