Effects of intervention on differential treatment of boys and girls in elementary physical education lessons
No full textThis study examined the effects of verbal and graphic feedback: on the distribution of
teacher verbal behaviors (positive and corrective feedback, praise, desist, and questioning)
and the teacher's use of student demonstrators during elementary coeducation
physical education lessons. Data were collected over a 3·month period on two female
nonphysical education specialist elementary teachers. A multiple baseline design was
used to show the efficacy of the treatment. The results indicated that in baseline both
teachers interacted with boys and girls inequitably on all variables. The intervention
package and daily follow-up were influential in establishing more equitable teacher
interaction patterns with boys and girls, The teachers' use of demonstrators was also
distributed more equitably between boys and girls following the intervention
Improving school lighting for video display units
No full textSchool lighting has in the past been relatively straightforward since the
predominant occupation has been one of reading dark letters (print) on a light (paper) background. However, with the prolific installation of video display units (VDU's) in schools and colleges, presently and anticipated in the future, the task now becomes one of reading light text on a dark screen. Thus the level and technique of lighting needs to be reassessed in order that VDU screen problems can be reduced or effectively eliminated. Problems arise not just from a bad or inefficient lighting system, but also from its interaction with the surrounding environment, i.e. wall surfaces, windows and furniture. Whether the terminals are installed in existing classrooms or designed for new ones, this article will allow the computer studies instructor to identify and implement the key characteristics which contribute to an efficient and comfortable VDU lighting installation
Comparison of infrared coagulation and rubber band ligation for first and second degree haemorrhoids: a randomised prospective clinical trial
No full textOne hundred and thirty seven previously untreated outpatients
with first and second degree haemorrhoids were
allocated at random to treatment by infrared coagulation
(n=66) or rubber band ligation (n= 71). Complete follow
up was obtained in 122 patients (60 who had undergone
infrared coagulation (group 1), and 62 rubber band
ligation (group 2)) at periods from three months to one
year after completion of treatment.
Infrared coagulation produced a satisfactory outcome
in 51 patients (85%): 34 were rendered asymptomatic and
17 improved. Rubber band ligation produced a satisfactory
outcome in 57 patients (92%): 33 were rendered
asymptomatic and 24 improved. Both methods were
equally effective in first and second degree haemorrhoids.
The incidence of side effects, particularly discomfort,
during and after treatment was significantly higher in
those treated by rubber band ligation (p <0 001). This
appeared to be an appreciable deterrent to future patient
compliance. The number of patients losing more than 24
hours from work was higher after rubber band ligation
than after infrared coagulation. The number of treatments
necessary to cure symptoms did not differ significantly
between the two methods. Infrared coagulation was significantly faster than rubber band ligation (p <0-001).
Infrared coagulation is a simple, fast, and effective
outpatient method for the treatment of first and second
degree haemorrhoids with fewer troublesome side effects
and higher patient acceptability than rubber band
ligation
The child ballad in Canada: a survey
No full textWhile many folklorists might find the tabulation of Child
ballad statistics a tedious and somewhat anachronistic exercise, few
would deny the historical value of describing in detail the results of
one phase of Canadian folksong research. It is our contention,
however, that such an exercise serves deeper scholarly concerns. As
an examination of a regional classical ballad repertoire, this survey
provides a base for comparison with other regions. Given the broad
geographic distribution and time depth represented by this genre,
the Child ballads are well suited for such comparative study. Moreover,
as the oldest level of the Anglo-Canadian song tradition, the
national Child ballad repertoire forms an important base for folksong
study within this country. An examination of maintenance
and loss of story types within the Child corpus, as well as analysis
of transformations undergone by individual ballads, could reveal
culturally-specific concerns which may be reflected throughout the
entire Canadian folksong repertoire
Invoice #31415 attached: Automated analysis of malicious Microsoft Office documents
No full textMicrosoft Office may be by far the most widely used suite for processing documents, spreadsheets, and
presentations. Due to its popularity, it is continuously utilised to carry out malicious campaigns. Threat
actors, exploiting the platform’s dynamic features, use it to launch their attacks and penetrate millions of
hosts in their campaigns.
This work explores the modern landscape of malicious Microsoft Office documents, exposing the means
that malware authors use. We leverage a taxonomy of the tools used to weaponise Microsoft Office documents and explore the modus operandi of malicious actors. Moreover, we generated and publicly shared
a specially crafted dataset, which relies on incorporating benign and malicious documents containing
many dynamic features such as VBA macros and DDE. The latter is crucial for a fair and realistic analysis,
an open issue in the current state of the art. This allows us to draw safe conclusions on the malicious
features and behaviour. More precisely, we extract the necessary features with an automated analysis
pipeline to efficiently and accurately classify a document as benign or malicious using machine learning
with an F1 score above 0.98, outperforming the current state of the art detection algorithms
