- A New E-Commerce Protocol: Proposing
a New Model for Facilitating Business to Consumer E-Commerce
Transactions
- By comparing the dominant entries in the B2C e-commerce marketplace
in terms of their security features, ease of implementation,
flexibility for merchants, and ease of use in day-to-day operations,
significant weaknesses in both security and convenience were
found. Many of these weaknesses can be mitigated using an XML
document to represent the transaction between merchant and acquirer.
This XML document can then be authenticated with a signed hash
shared between the acquirer and merchant. Many of the design
details required to implement such a system are specified and
discussed.

- Great Plains Free-Net User Management System
(UMS)
- The GPFN is embarking on a comprehensive modernization strategy.
As part of this strategy, GPFN is offering a number of new services
and adopting a more member-centric philosophy. One problem with
the existing User Management system is that very few volunteers
understand or can manage it. It relies on an inter-related set
of some 300 shell scripts and flat file tables from which to
manage its database. The new design utilizes a relational database
engine for the back-end and a secure, web-enabled interface
from which members, users, guests and volunteers can apply for
accounts, upgrade accounts and approve, reject or revoke applications
and accounts.
The system is designed to use a volunteer pool of developers
to develop and implement the new system.

- An Introduction to Bayesian
Networks and their Contemporary Applications
- Bayesian Networks are becoming an increasingly important
area for research and application in the entire field of Artificial
Intelligence. This paper explores the nature and implications
for Bayesian Networks beginning with an overview and comparison
of inferential statistics and Bayes' Theorem. The nature, relevance
and applicability of Bayesian Network theory for issues of advanced
computability forms the core of the current discussion. A number
of current applications using Bayesian networks is examined.
The paper concludes with a brief discussion of the appropriateness
and limitations of Bayesian Networks for human-computer interaction
and automated learning.

- The Disease Model of Alcoholism
Revisited: Why People Drink
- The view of alcoholism which currently boasts wide acceptance
is the disease model approach. This approach views alcohol as
a disease of the individual. Compared to a view of alcoholism
as moral degeneration, a personal weakness or failure, the disease
perspective is a more desirable approach in that it provides
both an impetus for treatment, assigns a profession to respond
to the problem, creates social sympathy and empathy for the
alcoholic, and removes or at least minimizes the guilt and reluctance
to seek treatment which the alcoholic experiences.
- But is it a disease? The medical model seems incapable of
"curing" this disease, offering instead only life-long
treatment combined with abstinence. This paper reviews the existing
literature supporting a disease model and then contrasts the
benefits and problems with this model against that of viewing
alcoholism as a learned behaviour using the paradigm of learning
psychology. A more comprehensive view of alcoholism, its causes
and possible treatment strategies results.

A
Community's Response to Free-Nets:
Implications for the Community-Based Telecomputing Movement in
Regina
A survey in May 1995 was conducted by the Great Plains Free-Net
Inc. The survey was intended to assist Great Plains Free-Net
in better understanding the needs of the community as well as
helping Great Plains Free-Net understand how to better communicate
its concept to the community as a whole and helping recruit
prospective information providers and determine interests among
the community. Also considered were questions related to the
demographics of prospective users, potential commitment by the
community to Great Plains Free-Net, and the times of anticipated
peak system usage.
A survey of Regina calling area homes resulted in 774 contacts
and 235 completed surveys.
These surveys found a strong interest in Great Plains Free-Net
as an information and connection service. 22% of the respondents
had heard about Great Plains Free-Net prior to the survey although
most of these had obtained their knowledge through friends,
colleagues or the newspaper.

Recovering the Divine Union through our Sexuality
- In the summer of 2005, the Evangelical Lutheran Church in
convention deliberates the question of how to respond to homosexual
or same sex couples and whether to bless these unions.
-
- This paper marks my contribution to the discussion of how
we understand Scripture and sexuality and how we must authentically
respond to gay, lesbian, bisexual and transgender people within
our churches.

- Brief on Interim Ministry
- In 2004, the Saskatchewan Synod of the Evangelical Lutheran
Church in Canada (ELCIC) began to draft a new policy on the
practice of Interim Ministry within the territory of the synod.
While this proposal seems to have started out as a practical
response to the particular issues faced by the synod (and to
a wider extent the Evangelical Lutheran Church in Canada at
a national level), the direction of this policy hints at some
more significant implications.
-
- In particular, the policy effectively redefines the Canadian
Lutheran understanding of ministry, ecclesial call, ordination,
and the role and division of powers between congregations and
their judicatory bodies. If left unaddressed, we may end up
with a church that is exists in stark contrast to the nature
of church first defined by the reformers. We may also end up
with a church that is even more impotent in any ability to proclaim
the Gospel within our modern milieu.
