Are nurses protected? Observing the risk of skin contamination when donning and doffing personal protective equipment, using a Canadian protocol.
No full textThis study aimed to determine whether the Public Services Health and Safety Association’s
donning and doffing protocol for Ebola are effective in the prevention of skin and clothing
contamination. Ten third-year nursing students performed a donning and doffing simulation,
which included donning personal protective equipment (PPE), being sprayed with GloGerm,
performing eight simulated movements, and doffing PPE. Fluorescent stains were observed
using an ultraviolet scan and were documented by their location and size. Four participants (N=4)
experienced at least one contamination event following the doffing of PPE. Contaminations were
observed on: the left dorsal lower leg (41.3mm; 64.0mm); the right dorsal lower leg (77.9mm); the
left plantar (9.5mm); the left index finger (2.8mm); the right middle finger (1.6mm); the left scapula
(38.1mm); and the right buttock (57.2mm). Areas of difficulty in the protocol included donning and
doffing: the gown, N95 respirator, and the outer footwear. Failures with the equipment, including
breaches and punctures, also contributed to the documented contamination. Near-miss incidents were
observed in nine of the twenty-four steps in the protocols and occurred a total of twenty times.
Revisions to the protocols were completed and included additional information for the following
protocol steps: hang hygiene, N95 respirator, gown, outer footwear, verification process
“Let’s Keep Ontario a Province of Opportunity for All Kids:” The Hall-Dennis Report, Ernie Checkeris, and the question of equality in Northern Ontario
No full textThis essay will demonstrate the impact of the Hall-Dennis report on Ernie Chcekeris' life in order to understand how he shaped the themes of multiculturalism, Indigenous rights and French-language schooling as they came to fruition in Ontario’s education system.
This paper will not assess the impact of the Hall-Dennis Report on the education system but rather explain how the Report was influenced by Checkeris and how his experiences on the Committee would reappear in other areas of his professional life. The first line of the Hall-Dennis Report explained that “the underlying aim of education is to further man’s unending search for truth. Once he possesses the means to truth, all else is within his grasp
Ground electromagnetic experiments to investigate the possibility of using an airborne electromagnetic system to detect nuclear magnetic resonance associated with unbound water in the subsurface
Get PDFGround-based geophysical experiments were undertaken to test the possibility of de-
tecting groundwater using nuclear magnetic resonance from an airborne electromagnetic
prospecting system. Two experimental surveys were conducted: One over an ice-covered
lake, containing a large volume of freshwater, and the other over an equal volume of
land, with little to no freshwater in the subsurface. If exposed to a radio-frequency pulse
at the Larmor frequency, protons in water molecules create a magnetic eld oscillating
at the Larmor frequency. Both surveys used a 120-second long frequency sweep from
2300 to 2400 Hz. It was initially hypothesized that as the frequency passed over the
Larmor frequency, 2348 Hz, there would be phase shift between the transmitter and
receiver signals. Phase measurements, using the heterodyne method, between the lake
and land data proved to be inconclusive, although the lake data showed an oscillatory
decay in the o -time, not equal to the Larmor frequency
Adapting methodologies from the forestry industry to measure the productivity of underground hard rock mining equipment
No full textThe purpose of this dissertation is to develop and apply a framework to characterize the ground
support installation component of the mining development cycle in underground hard rock mines
for the purposes of comparing equipment. A secondary goal is to identify opportunities to
improve the productivity of the ground support installation process.
It was found that the forestry industry faces similar challenges as the mining industry when
measuring equipment output in a variable environment where equipment productivity is affected
by a range of external conditions. Despite this challenge, forestry researchers successfully
developed and applied a standardized methodology and nomenclature to measure the
productivity of equipment for the purposes of equipment and process comparison in variable
external conditions. The methodology used in the forestry industry was modified to measure mechanized and semimechanized
ground support installation productivity in three Canadian underground hard rock
mines. Furthermore, opportunities to improve the ground support installation process were
identified. This framework can be modified to measure and compare other types of mining
equipment. By using a standardized methodology to measure, compare and improve mining
processes, development and production rates can be increased in underground hard rock mines.
In summary, a framework was adapted from the forestry industry to measure and compare the
productivity of the ground support installation cycle in three Canadian hard rock mines, and
opportunities to improve the process were found
The impact of professional experience on teaching conceptions in university -case studies from Tunisia
Get PDFHigher education is a contract between professor and student; which
specifies what each pole can expect from the other (Johnson, 1995). The
strategies, techniques and devices used by teachers to achieve their personal,
scientific and technical purposes during their lessons are the subject of various
researches in didactics. This research is in line with the scientific orientation
of clinical didactics, which is characterized by a double theoretical and
epistemological affiliation: didactics and clinical psychoanalytic inspiration.
We are interested in the singularity of the subject teachers taken in didactics.
In Tunisia, most higher education teachers do not have professional and
continuous education in pedagogy and didactics, and no follow-up in their
careers. As if the question did not arise and the ability to accompany students,
to develop their critical thinking skills and to promote their learning was self-evident. The aim of this work is to insist on the importance of continuing
education and professional development of experienced university teachers
Relational aggression, antisocial behaviour, and psychopathy in Canadian female offenders.
Get PDFInterest in the expression of female aggression, antisocial behaviour, and psychopathy
has grown in recent years as a result of steadily increasing incarceration rates of women in
Canada (38.6% over the past 10 years). Previous research suggests that the relational nature of
female aggression, in offender and non-offender samples, differentiates women from their male
counterparts. Whereas males tend to be physically aggressive, relational aggression is the most
common form of aggression employed by women, is associated with psychopathic traits, and has
been found to predict criminal activity. As research pertaining to these factors in adult female
offenders is in its infancy, it is imperative that the role of relational aggression in incarcerated
women, both violent and non-violent, be further explored. To this end, a mixed method design
was implemented, including 56 female offenders recruited from three correctional facilities in Ontario, Canada. All participants completed a series of questionnaires measuring relational
aggression, antisocial behaviour, and psychopathy. Sixteen participants also participated in
semi-structured interviews querying their lived experiences of relational aggression in a custodial
setting. All participants, regardless of being identified as violent or non-violent offenders,
disclosed experiencing victimization by way of relational aggression while serving their sentence
and the majority acknowledged acting as perpetrators. Emerging from the results was a fivestage
descriptive model detailing the process through which dominant female inmates employ
relationally aggressive tactics (e.g., gossiping/rumour spreading, guilt induction, malicious
humour, social exclusion, and social manipulation) to establish and maintain social hierarchies
on their respective units. The presence of several psychopathic traits also emerged that prove useful in social hierarchy development; more specifically, both violent and non-violent women
exhibited a certain level of machiavellianism, callousness, social influence, rebelliousness, and impulsivity. Callousness, specifically, was found to significantly predict relational aggression
perpetration in those who also have more substantial histories of victimization by way of the
same relationally aggressive tactics. Additional results pertaining to female antisocial behaviour
and the observed psychopathic traits in the current sample are reported. Recommendations for
future research, training, and assessment are proposed
Applying teeline shorthand using leap motion controller
Get PDFA hand gesture recognition program was developed to recognize users’ Teeline
shorthand gestures as English letters, words and sentences using Leap Motion
Controller. The program is intended to provide a novel way for the users to interact
with electronics by waving gestures in the air to input texts instead of using keyboards.
In the recognition mode, the dynamic time warping algorithm is used to compare the
similarities between different templates and gesture inputs and summarize the
recognition results; in the edit process, users are able to build their own gestures to
customize the commands. A series of experiment results show that the program can
achieve a considerable recognition accuracy, and it has consistent performance in face
of different user groups
The effects of perfectionism on decisional delay under conditions of perceived risk
Get PDFThe present study sought to explore and expand the knowledge regarding the fairly novel body of literature looking at perfectionism and the decision-making process called decisional delay. More specifically, this study begins to examine the potential influence of perfectionism on indicators of decisional delay, selection difficulty, and stress reactivity involved in decision-making processes. This study examined the predictive relationships between perfectionism, decisional delay, selection difficulty and stress reactivity in a sample of undergraduate students (N = 90) following random assignment to one of two (low, high) risk conditions on a reward selection decision-making task. Overall, analyses showed that dimensions of perfectionism carried mixed predictive abilities for selection difficulty and stress reactivity on a decision-making task. Patterns of results indicated that those higher in dimensions that encompass critical self-evaluations, concerns with error, and threat of failure, were predictive of increases in difficulties deciding and heightened stress. Moreover, results showed that the perfectionism dimension characterized by personal standards, which arguably contains adaptive capacities, was not predictive of selection difficulty and stress reactivity. Finally, findings demonstrated that perfectionism was not predictive of the reaction time decisional delay indicator. The results are discussed in terms of practical implications, as well as future directions
Establishing user immersion of consumer virtual reality products through qualitative measurement
Get PDFNew consumer technologies such as the Oculus Rift and other head-mounted displays
(HMDs) in the field of virtual reality (VR) have introduced another method of
experiencing immersive content. The effectiveness of these new mediums can be compared
to more traditional products that are currently in use; such as televisions, desktop
monitors, and variations which include 3D display capabilities. This raises the question of
whether there is a notable difference between the immersive experiences each medium can
offer. This study hypothesized that a significant difference in immersion could be
identified between consumer devices. Also, using qualitative analysis, an attempt to identify
what consumers believe comprises immersion could be devised. Data from 30 participants
indicated that the immersive potential of consumer devices can be differentiated and
compared. In addition the understanding of the term “immersion” is not clearly
understood or shared by consumers
How does reading support resilience? An interdisciplinary narrative study with children and adults
No full textAnecdotal evidence suggests that adults are very much influenced by what they read as children.
This interdisciplinary thesis examines the effect that reading books and stories can have to
support resilience strategies. It centers on the following research question: How does the reading
of text-based narratives (in children’s literature) support the development of resilience in
children (ages 10 – 13 years)? In this question, reading refers to recreational reading; narrative
refers to a textual story; and resilience refers to the ability of the reader to adapt to situations.
This thesis reviews and combines key concepts about how readers engage with narratives and the
act of reading. It examines literatures from education, literary theory, reader-response theory,
bibliotherapy, human development and library science. Fifteen children between the ages of 10
and 13 years and sixteen adults between the ages of 18 and 91 years were interviewed. Analysis
of the data, both thematic and narrative results, indicate that both the act of reading for pleasure
and the narrative being read support positive coping strategies (such as self-regulation). Such
strategies help to build resilience in human beings. Responses from participants assisted in
providing a model of coping skills and positive behaviour. For example, the act of reading itself becomes a recovery mechanism in response to coping with stressful situations. Implications for
further research into reading and mood-management and the benefits of re-reading are presented
