COMPUTER-ASSISTED INSTRUCTION OF MATHEMATICAL OPERATIONS IN ADHD AND TYPICAL STUDENTS – THE ONLINE LEARNING EXPERIENCE

This study examines the effectiveness of Computer – Assisted Instruction (CAI) on mathematical operations of addition and subtraction performance of students diagnosed with Attention Deficit / Hyperactivity Disorder and their typical peers, in the context of an online Learning Management System. The mathematical operation performance of students was assessed right before, just after and after three months’ time in “paper and pencil” and CAI conditions in order to determine maintenance of intervention’s effects. Six ADHD students diagnosed by public centers of diagnosis and attending 1st to 3rd grades of elementary school took part in the study. They were facing minor to major difficulties in mathematical operations of addition and subtraction. Twelve typical students of the same age and with no mathematical difficulties also took part. The research method was an experimental 2 (groups) X 4 (conditions) nonequivalent-control group design was created as students were different by ADHD existence. Typical students had significantly better performance in mathematical operations prior, after and in CAI implementation compared to the ADHD students with major problems. Their performance was actually in the same levels with students with ADHD with minor difficulties. Examination of within ADHD subjects revealed significant differences when CAI implemented. CAI found to be an effective instructional strategy on mathematical operations’ performance either of students with ADHD or non-disabled in a “working at home” educational setting. Although all students had gains from CAI implementation, a “Mathew” effect was revealed, as typical and ADHD students with minor difficulties had better performance gains which were maintained more after treatment and a follow up examination after three months.  Article visualizations

Airborne Advanced Reconfigurable Computer System (ARCS)

A digital computer subsystem fault-tolerant concept was defined, and the potential benefits and costs of such a subsystem were assessed when used as the central element of a new transport's flight control system. The derived advanced reconfigurable computer system (ARCS) is a triple-redundant computer subsystem that automatically reconfigures, under multiple fault conditions, from triplex to duplex to simplex operation, with redundancy recovery if the fault condition is transient. The study included criteria development covering factors at the aircraft's operation level that would influence the design of a fault-tolerant system for commercial airline use. A new reliability analysis tool was developed for evaluating redundant, fault-tolerant system availability and survivability; and a stringent digital system software design methodology was used to achieve design/implementation visibility

Exploratory analysis of Internet of Things (IoT): revolutionizing the grocery retail industry

This dissertation has investigated the consequences of implementing Internet of Things (IoT) technologies in grocery retailing by analyzing customers' perceptions of eight prominent technologies. The objective was to investigate and explore to what degree implementing these technologies would impact the customer experience. Based on secondary research, this thesis focuses on eight prominent technologies that presumably will encounter an increasing utilization in the visible future; Self-Scanning, Smart Robots, Smart Shelves, Smart Shopping Cart, Smart Fridge, Just Walk Out, Personalized Promotion/Pricing, and Mobile Apps. The technology distribution varies across different stages in the customer journey, and research indicates that IoT has the most significant impact in the pre-purchase stage. A comprehensive exploratory survey was conducted through Amazon mTurk with a wide range of respondents (n=204), giving valuable insight into demographic differences' influence on each technology perception. The investigation uncovered vast differences in several areas such as age, attitude, and privacy. Among other findings, the age segment 35-44 is more confident towards IoT technology than the age segment 55+, and shoppers with a positive attitude towards grocery shopping have higher confidence towards the technologies than shoppers with a negative attitude. On a widespread basis, the findings revealed that all eight technologies would positively affect customer experience to a certain level.

Personal computers and the liberating aspects for human creativity

This narrative inquiry study of selected adults from the UNCG faculty and staff focused on seeking out positive feelings which occur when this group of people use personal computers. A preliminary survey was mailed to identify participants who would be interviewed. The names had been gathered from C-TEP grant recipients, faculty, and staff on campus. Twenty-one adults ranging from 21 to 59 years of age were interviewed. Seven who were from different departments on campus were selected for description, including two females and five males. The interviews were transcribed and analyzed for recurring themes. The major themes which emerged were learning style, rising expectations, playfulness, liberation, and creativity. Each theme with the attained rich data is presented in narrative form
