Learning Differences in E-Commerce I Online Classes in Public Secondary Schools in North Carolina.

The purpose of this study was to measure differences in learning styles in an online E-Commerce I class in public secondary schools in North Carolina. Students\u27 observations and achievements were evaluated by gender, grade level, course of study, online experience, and expected grade. This type of study could identify relationships between the online model and the four areas evaluated. This information may aid designers of online curricula as well as the teachers. The literature review covered several topics including technology, online learning, gender-based education, learning styles, maturity, and expectations. Each topic was related to the success of students in an online environment. This quantitative study was conducted using a survey-design method. The survey was designed using online survey software. Specifically, the survey concentrated on the differences and successes in an online class. With online education growing in popularity, educators need to evaluate the reasons behind success or failure. Independent sample t tests and a one way ANOVA were used to determine the significance of each research question. The survey dealt with 3 different dimensions, the learning style dimension, the experience dimension, and the opinion dimension. Findings showed significant differences in 2 areas, age and expected grade. The data showed a significant difference between juniors and seniors in all 3 dimensions of the survey. The findings also showed significant findings in all 3 dimensions of the survey in regard to expected grade. Recommendations for future research, conclusions, and recommendations for practice are also included

Australian universities, generic skills and lifelong learning

The concept of lifelong learning implies a cycle where the learner contributes prior learning into a new learning environment and sees that learning upgraded. In recent years, a range of internal and external pressures have encouraged Australian universities to identify the meta or generic skills embedded in tertiary study. Using a content analysis of relevant university policy documents, this study assesses how the Australian higher education sector has presented this discussion through the notion of ‘graduate attributes’ and then analyses the implications of this conceptual transition. This article argues that the shift from a notion of generic skills to graduate attributes both reinforces and encourages universities to concentrate their participation in lifelong learning at one particular end of the cycle. This study suggests that, whilst informal experience is increasingly incorporated into university admission processes and even into credit for courses, progression towards a more equitable and accessible higher education sector remains patchy at best

Posterior cricoid region fluoroscopic findings: the posterior cricoid plication.

The region posterior to the cricoid cartilage is challenging to assess fluoroscopically. The purpose of this investigation is to critically evaluate the posterior cricoid (PC) region on fluoroscopy and describe patterns of common findings. This was a case control study. All fluoroscopic swallowing studies performed between June 16, 2009, and February 9, 2010, were reviewed for features seen in the PC region. These findings were categorized into distinct patterns and compared to fluoroscopic studies performed in a cohort of normal volunteers. Two hundred patient studies and 149 healthy volunteer studies were reviewed. The mean age of the referred patient cohort and the volunteer cohort was 57 years (±19) and 61 years (±16), respectively (p > 0.05). The patient cohort was 53% male and the control cohort was 56% female (p > 0.05). Four groups were identified. Pharyngoesophageal webs were seen in 7% (10/149) of controls and 14% (28/200) of patients (p = 0.03). A PC arch impression was seen in 16% of patients (32/200) and controls (24/149) (p = 1). A PC plication was demonstrated in 23% (34/149) of controls and 30% (60/200) of patients (p = 0.13). No distinctive PC region findings were seen in 54% (81/149) of controls and 42% (84/200) of referred patients (p = 0.02). Four patients (2%) had both a web and a PC plication. Four categories of PC region findings were identified (unremarkable PC region, web, PC arch impression, and PC plication). Both patients referred for swallowing studies and healthy volunteers demonstrated esophageal webs, PC arch impressions, and PC plications. Only webs were more common in patients than in control subjects (p = 0.03). The PC impression and PC plication are likely to represent normal variants that may be identified on fluoroscopic swallow studies

A Gamefied Synthetic Environment for Evaluation of Counter-Disinformation Solutions

This paper presents a simulation-based approach to countering online dis/misinformation. This disruptive technology experiment incorporated a synthetic environment component, based on adapted SIR epidemiological model to evaluate and visualize the effectiveness of suggested solutions to the issue. The participants in the simulation were given a realistic scenario depicting a dis/misinformation threat and were asked to select a number of solutions, described in IoS (Ideas-of-Systems) cards. During the event, the qualitative and quantitative characteristics of the IoS cards, were tested in a synthetic environment (SEN), built after a Susceptible-Infected-Resistant (SIR) model. The participants, divided into teams, presented and justified their dis/misinformation strategy which included three IoS card selections. A jury of subject matter experts, announced the winning team, based on the merits of the proposed strategies and the compatibility of the different cards, grouped together

The relationship between Hippocampal asymmetry and working memory processing in combat-related PTSD: a monozygotic twin study

BACKGROUND: PTSD is associated with reduction in hippocampal volume and abnormalities in hippocampal function. Hippocampal asymmetry has received less attention, but potentially could indicate lateralised differences in vulnerability to trauma. The P300 event-related potential component reflects the immediate processing of significant environmental stimuli and has generators in several brain regions including the hippocampus. P300 amplitude is generally reduced in people with PTSD. METHODS: Our study examined hippocampal volume asymmetry and the relationship between hippocampal asymmetry and P300 amplitude in male monozygotic twins discordant for Vietnam combat exposure. Lateralised hippocampal volume and P300 data were obtained from 70 male participants, of whom 12 had PTSD. We were able to compare (1) combat veterans with current PTSD; (2) their non-combat-exposed co-twins; (3) combat veterans without current PTSD and (4) their non-combat-exposed co-twins. RESULTS: There were no significant differences between groups in hippocampal asymmetry. There were no group differences in performance of an auditory oddball target detection task or in P300 amplitude. There was a significant positive correlation between P300 amplitude and the magnitude of hippocampal asymmetry in participants with PTSD. CONCLUSIONS: These findings suggest that greater hippocampal asymmetry in PTSD is associated with a need to allocate more attentional resources when processing significant environmental stimuli.Timothy Hall, Cherrie Galletly, C.R.
