Failed and fragile states that result from intrastate war pose severe threats to the security of both the international system and individual states alike. In the post-Cold War era, the international community has come to recognize the reality of these threats and the difficulty involved in ending violence and building sustainable peace in failed and fragile states. This work focuses upon the development of a comprehensive strategy for sustainable peace-building by incorporating the tenets of the human security doctrine into the peace-building process. Through the use of case studies of The Former Yugoslav Republic of Macedonia and East Timor, the development and refinement of the doctrine of human security will occur, as well as, an understanding of how and where human security fits into the sustainable peace-building equation. The end result of the analysis is the development of a hierarchical pyramid formation that brings together human security and peace-building into one framework that ultimately creates the foundation and structure of sustainable peace-building. With the development of a sustainable peace-building structure based upon the human security doctrine, the role of Canada in the support of sustainable peace-building is analyzed in relation to the form and level of involvement that Canada undertakes and contributes to in the implementation and support of sustainable peace-building initiatives. Following from this, recommendations are provided regarding what role(s) Canada should undertake in the sustainable peace-building process that take into consideration the present and likely future capabilities of Canada to be involved in various aspects of the peace-building process. ii This paper outlines the need for a peace-building strategy that is designed to be sustainable in order that failed and fragile states resulting from intrastate conflict do not regress or collapse back into a condition of civil war, and subsequently designs such a strategy. The linking of peace-building and human security creates the required framework from which sustainable peace-building is derived. Creating sustainable peace is necessary in order to increase the likelihood that both present and future generations existing in failed and fragile states will be spared from the scourge of intrastate war.

The effects of manipulated augmented sensory feedback on error detection when using a touch screen

The purpose of the present study was to determine which augmented sensory modality would best develop subjective error-detection capabilities of learners performing a spatial-temporal task when using a touch screen monitor. Participants were required to learn a 5-digit key-pressing task in a goal time of 2550 ms over 100 acquisition trials on a touch screen. Participants were randomized into 1 of 4 groups: 1) visual-feedback (colour change of button when selected), 2) auditory-feedback (click sound when button was selected), 3) visual-auditory feedback (both colour change and click sound when button was selected), and 4) no-feedback (no colour change or click sound when button was selected). Following each trial, participants were required to provide a subjective estimate regarding their performance time in relation to the actual time it took for them complete the 5-digit sequence. A no-KR retention test was conducted approximately 24-hours after the last completed acquisition trial. Results showed that practicing a timing task on a touch screen augmented with both visual and auditory information may have differentially impacted motor skill acquisition such that removal of one or both sources of augmented feedback did not result in a severe detriment to timing performance or error detection capabilities of the learner. The present study reflects the importance of multimodal augmented feedback conditions to maximize cognitive abilities for developing a stronger motor memory for subjective error-detection and correction capabilities.

Cytosolic calcium levels and stress induced y-amino butyrate synthesis in asparagus mesophyll cells

Numerous investigations have demonstrated large increases in y-amino butyrate (GABA) levels in response to a variety of stresses such as touch or cold shock (Wallace et ale 1984) Circumstantial evidence indicating a role of Ca2 + in these increases includes elevated Ca2+ levels in response to touch and cold shock (Knight et ale 1991), and the demonstration of a calmodulin binding domain on glutamate decarboxylase (GAD), the enzyme responsible for GABA synthesis (Baum et al 1993) In the present study the possible role of Ca2+ and calmodulin in stimulation of GAD and subsequent GABA accumulation was examined using asparagus mesophyll cells. Images of cells loaded with the Ca2+ indicator Fluo-3 revealed a rapid and transient increase in cytosolic Ca2+ in response to cold shock. GABA levels increased by 106% within 15 min. of cold shock. This increase was inhibited 70% by the calmodulin antagonist W7, and 42% by the Ca2+ channel blocker La3+.. Artificial elevation of intracellular Ca2+ by the Ca2+ionophore A23187 resulted in an 61% increase in GABA levels. Stimulation of GABA synthesis by ABA resulted in an 83% increase in GABA levels which was inhibited 55% by W7. These results support the hypothesis that cold shock stimulates Ca2+ entry into the cytosol of the cells which results in Ca2+/calmodulin mediated activation of GAD and consequent GABA synthesis.

Photograph - William Bliss Carman and Miss M. B. Stevenson, September 1927

A photograph of poet William Bliss Carman and M. B. Stevenson in New Canaan, Connecticut. The photograph from September 1927 was sent to fellow poet Ethelwyn Wetherald in 1932. It was included in a four page letter from Carman to Wetherald. Carman, also Canadian, spent most of his years in the United States, but in his letter he mentions that he "regrets" he cannot keep in closer touch with his fellow Canadian poets.

Effects of Cerebral Blood Flow and PETCO2 on Cognitive Function During Passive Heat Stress

This thesis tested whether cognitive performance during passive heat stress may be affected by changes in cerebrovascular variables as opposed to strictly thermally-induced changes. A pharmacological reduction in cerebral blood flow (CBF) using indomethacin along with a hypocapnia-induced CBF reduction during passive heat stress (Tre ~1.5°C above baseline) were used to investigate any cerebrovascular-mediated changes in cognitive performance. Repeated measures analysis of variance indicated that One-Touch Stockings of Cambridge (OTS) performance was not affected by a significant reduction in CBF during passive heat stress. More specifically, OTS accuracy measures did not change as a result of either a reduction in CBF or increasing passive heat stress. However, it was found that OTS response time indices improved with increasing passive heat stress independent of CBF changes. In conclusion, a significant reduction in CBF does not cause additional changes in performance of an executive functioning task during severe passive heat stress.
