An Inquiry into Retention and Achievement Differences in Campus Based and Web Based AP Classes

A decade ago the Advanced Placement (AP) program was introduced into the Canadian province of Newfoundland and Labrador. Initially, schools embraced this opportunity to provide their students with opportunities that were previously unavailable. However, within a few years the AP program was relegated to urban and large regional high schools. Few smaller, and particularly rural schools, were able to offer AP courses only to the brightest one or two students taking it as an independent study. In 1997-98, schools began to delivery AP courses in a web-based method. The purpose of the study is to examine the retention rates and student achievement in AP courses in the province between different delivery models

Student Performance in Virtual Schooling: Looking Beyond the Numbers

Seven years ago the Centre for Distance Learning and Innovation began a virtual high school within the Canadian province of Newfoundland and Labrador. Designed primarily to provide courses in specialized areas to students in rural areas, where schools have difficulty in attracting these teachers, there is concern that the opportunities provided by this virtual school are “second rate.” The purpose of the study is to examine the student achievement in standardized public exams and final course scores in the province between different delivery models, geographic location and subject area to determine whether or not students are succeeding in the virtual high school environment at the same rate as their classroom counterparts

Beyond Volunteerism and Good Will: Examining the Commitment of Schoolbased Teachers to Distance Education

Two decades ago Newfoundland and Labrador introduced distance education in the K-12 environment. The program focused upon providing advanced-level courses to rural school students, and worked largely due to the widely known, but rarely documented significant amounts of content-based assistance from school based personnel. In the past seven years the province has moved to a virtual school model of distance education and more rural schools find that they must rely upon this virtual school to offer academic-level courses to students with a wide range of abilities. This has created many new responsibilities for teachers that have also gone undocumented. Studies that document the duties and time required to provide support for this new models of distance education are vital, as research is suggesting that this school-based personnel is vital to student success

How Are They Doing?: Examining Student Achievement in Virtual Schooling

Six years ago the Centre for Distance Learning and Innovation began a virtual high school within the Canadian province of Newfoundland and Labrador. Designed primarily to provide courses in specialized areas to students in rural areas, where schools have difficulty in attracting second language, mathematics and science teachers. However, there has been some concern that the opportunities provided by this virtual high school are second rate or only able to cater to independent, self-motivated students. The purpose of the study is to examine the student achievement in standardized public exams and final course scores in the province between different delivery models to determine whether or not students are succeeding in the virtual high school environment at the same rate as their classroom counterparts

The Straight Truth about Online Learning in the Straits: An Investigation into the Nature of Education in a Rural and Remote Region of Newfoundland and Labrador

This paper reports on a naturalistic research project that was conducted in response to the educational concerns of the coastal rural communities of Labrador Straits. The research project investigated the current provision of education available to the children and the youth of these communities and found that due to declining population, changing demographics, lack of qualified teaching staff in the region and several other interrelated factors, there was an increased reliance on online learning in the small rural schools of the Straits as well as other rural regions of the province

Interoceptive training to target anxiety in autistic adults (ADIE): a single-center, superiority randomized controlled trial

Background This trial tested if a novel therapy, Aligning Dimensions of Interoceptive Experience (ADIE), reduces anxiety in autistic adults. ADIE targets the association of anxiety with mismatch between subjective and behavioral measures of an individual's interoceptive sensitivity to bodily signals, including heartbeats. Methods In this superiority randomized controlled trial, autistic adults (18–65 years) from clinical and community settings in Southern England were randomly assigned (1:1) to receive six sessions of ADIE or an active ‘exteroceptive’ control therapy (emotional prosody identification). Researchers conducting outcome assessments were blind to allocation. ADIE combines two modified heartbeat detection tasks with performance feedback and physical activity manipulation that transiently increases cardiac arousal. Participants were followed-up one-week (T1) and 3-months post-intervention (T2). The primary outcome was Spielberger Trait Anxiety Score (STAI-T) at T2. Outcomes were assessed on an intention-to-treat basis using multiple imputation for dealing with missing values. This trial was registered at International Standard Randomized Controlled Trial Registry, ISRCTN14848787. Findings Between July 01, 2017, and December 31, 2019, 121 participants were randomly allocated to ADIE (n = 61) or prosody (n = 60) intervention groups. Data at T1 was provided by 85 (70%) participants (46 [75%] ADIE; 39 [65%] prosody). Data at T2 was provided by 61 (50%) participants (36 [59%] ADIE; 25 [42%] prosody). One adverse event (cardiac anxiety following ADIE) was recorded. A statistically significant group effect of ADIE on trait anxiety continued at T2 (estimated mean difference 3•23 [95% CI 1•13 to 5•29]; d = 0•30 [95% CI 0•09 to 0•51]; p = 0•005) with 31% of ADIE group participants meeting trial criteria for recovery (compared to 16% in the control group). Interpretation ADIE can reduce anxiety in autistic adults, putatively improving regulatory control over internal stimuli. With little reliance on language and emotional insight, ADIE may constitute an inclusive intervention

Sulfur trioxide formation/emissions in coal‐fired air‐ and oxy‐fuel combustion processes: a review

In oxy‐fuel combustion, fuel is burned using oxygen together with recycled flue gas, which is needed to control the combustion temperature. This leads to higher concentrations of sulfur dioxide and sulfur trioxide in the recycled gas, which can result in the formation of sulfuric acid and enhanced corrosion. Current experimental data on SO3 formation, reaction mechanisms, and mathematical modelling have indicated significant differences in SO3 formation between air‐ and oxy‐fuel combustion for both the wet and dry flue gas recycle options. This paper provides an extensive review of sulfur trioxide formation in air‐ and oxy‐fuel combustion environments, with an emphasis on coal‐fired systems. The first part summarizes recent findings on oxy‐fuel combustion experiments, as they affect sulfur trioxide formation. In the second part, the review focuses on sulfur trioxide formation mechanisms, and the influence of catalysis on sulfur trioxide formation. Finally, the current methods for measuring sulfur trioxide concentration are also reviewed along with the major difficulties associated with those measurements using data available from both bench‐ and pilot‐scale units

Determining the pharmacokinetics of nicotinic drugs in the endoplasmic reticulum using biosensors

Nicotine dependence is thought to arise in part because nicotine permeates into the endoplasmic reticulum (ER), where it binds to nicotinic receptors (nAChRs) and begins an “inside-out” pathway that leads to up-regulation of nAChRs on the plasma membrane. However, the dynamics of nicotine entry into the ER are unquantified. Here, we develop a family of genetically encoded fluorescent biosensors for nicotine, termed iNicSnFRs. The iNicSnFRs are fusions between two proteins: a circularly permutated GFP and a periplasmic choline-/betaine-binding protein engineered to bind nicotine. The biosensors iNicSnFR3a and iNicSnFR3b respond to nicotine by increasing fluorescence at [nicotine] 75%. Reducing nicotine intake by 10-fold decreases activation to ∼20%. iNicSnFR3a and iNicSnFR3b also sense the smoking cessation drug varenicline, revealing that varenicline also permeates into the ER within seconds. Our iNicSnFRs enable optical subcellular pharmacokinetics for nicotine and varenicline during an early event in the inside-out pathway
