Reducing Hardships: Student Motivations, Educational Workflows, and Technology Choices in Academic Settings
Objective – This study examines The University of Manitoba student attitudes toward technology’s role in University study spaces and in their own educational workflows.
Methods - A series of semi-structured group interviews were conducted with current undergraduate and graduate students at The University of Manitoba. Three group interviews were conducted with questions about individual technology and space use while studying in the library, and three group interviews were conducted with questions about group collaboration using technologies and tools in group study spaces. Transcripts were coded iteratively and separately by the researchers, analyzed for interrater reliability, categorized, and reviewed using axial coding to identify major themes. Through continued examination of these themes, a single theory emerged.
Results - The participants expressed a strong need for independence and feelings of control over their workflows, technological tools, and environments. They discussed how interpersonal concerns and anxieties motivated their workflow choices and acknowledged the (often conflicting) motivational forces of personal necessity and personal preference. When examining the motivations behind the selection of technologies and work practices, it became clear that the respondents make technology and workflow decisions in an attempt to minimize their experience of perceived hardships. These perceived hardships could be social, emotional, educational, environmental, or temporal in nature, and the weight of any one hardship on decision making varied according to the individual.
Conclusions - Libraries should be aware of this foundational user motivation and make choices accordingly - identifying and minimizing hardships whenever possible, unless they are necessary to achieve learning or service-specific goals. Additional research is required to help articulate the nuances experienced by particular student demographics. Librarians and future researchers should also consider investigating the potential disconnect between librarian and user attitudes toward technology, the prioritization of user-centered decision-making, and whether or not systematically disadvantaged social groups have different attitudes toward technology and its place in library spaces and academic work.https://journal.lib.uoguelph.ca/index.php/perj/article/view/545
Fast Variations of Gamma-Ray Emission in Blazars
The largest group of sources identified by EGRET are Blazars. This sub-class
of AGN is well known to vary in flux in all energy bands on time-scales ranging
from a few minutes (in the optical and X-ray bands) up to decades (radio and
optical regimes). In addition to variations of the gamma-ray flux between
different viewing periods, the brightest of these sources showed a few
remarkable gamma-ray flares on time-scales of about one day, confirming the
extension of the ``Intraday-Variability (IDV)'' phenomenon into the GeV range.
We present first results of a systematic approach to study fast variability
with EGRET data. This statistical approach confirms the existence of IDV even
during epochs when no strong flares are detected. This provides additional
constraints on the site of the gamma-ray emission and allows cross-correlation
analyses with light curves obtained at other frequencies even during periods of
low flux. We also find that some stronger sources have fluxes systematically
above threshold even during quiescent states. Despite the low count rates this
allows explicit comparisons of flare amplitudes with other energy bands.Comment: 5 pages including figures, LaTex, uses aipproc.sty, to appear in the

Modula-2*: An extension of Modula-2 for highly parallel programs
Parallel programs should be machine-independent, i.e., independent of properties that are likely to differ from one parallel computer to the next. Extensions are described of Modula-2 for writing highly parallel, portable programs meeting these requirements. The extensions are: synchronous and asynchronous forms of forall statement; and control of the allocation of data to processors. Sample programs written with the extensions demonstrate the clarity of parallel programs when machine-dependent details are omitted. The principles of efficiently implementing the extensions on SIMD, MIMD, and MSIMD machines are discussed. The extensions are small enough to be integrated easily into other imperative languages
A comprehensive literature review of juvenile programs, policies, and monitoring systems
This paper investigates past literature on juvenile-based programs, policies, and monitoring systems. It shows what strides practitioners have taken to reduce recidivism and how programs have tried to limit past failures. By showing what has worked and what has failed, we can develop future research and designs, measure the effects of different theories, and even add more important categories to future programs. This research presents information that may assist practitioners who work directly with juveniles and those who are involved in researching and developing future juvenile programs and policies
Loopless Gray Code Enumeration and the Tower of Bucharest
We give new algorithms for generating all n-tuples over an alphabet of m letters, changing only one letter at a time (Gray codes). These algorithms are based on the connection with variations of the Towers of Hanoi game. Our algorithms are loopless, in the sense that the next change can be determined in a constant number of steps, and they can be implemented in hardware. We also give another family of loopless algorithms that is based on the idea of working ahead and saving the work in a buffer
