    The breakfast series

    The purpose of this project was to produce visual work that examined a possible nostalgia that unfolds around the breakfast meal. The method of examination involved creating a process breakfast that was followed thirty times. The result of following this process was the taking of three hundred Polaroids that were then edited for their potential to visually reconstruct the ideal process breakfast. This process of discovery has resulted in a number of significant insight into the narrative of breakfast: that an idealized narrative could exist in the visualization of the process breakfast; that elements of nostalgia that may exist within the work are contingent on the viewer; and the level of authenticity of the project affects the nature of the idealization in effect

    Effect of type of otolith and preparation technique on age estimation of larval and juvenile spot (Leiostomus xanthurus)

    Otoliths of larval and juvenile fish provide a record of age, size, growth, and development (Campana and Neilson, 1985; Thorrold and Hare, 2002). However, determining the time of first increment formation in otoliths (Campana, 2001) and assessing the accuracy (deviation from real age) and precision (repeatability of increment counts from the same otolith) of increment counts are prerequisites for using otoliths to study the life history of fish (Campana and Moksness, 1991). For most fish species, first increment deposition occurs either at hatching, a day after hatching, or after first feeding and yolksac absorption (Jones, 1986; Thorrold and Hare, 2002). Increment deposition before hatching also occurs (Barkmann and Beck, 1976; Radtke and Dean, 1982). If first increment deposition does not occur at hatching, the standard procedure is to add a predetermined number to increment counts to estimate fish age (Campana and Neilson, 1985)

    Multiple Mating Results in Multiple Paternity in Richardson's Ground Squirrels, Spermophilus richardsonii

    Microsatellite DNA primers developed from Columbian Ground Squirrels (Spermophilus columbianus) were used to establish paternity in a Manitoba population of Richardsonā€™s Ground Squirrels (Spermophilus richardsonii). Primers resolving variation at six microsatellite loci allowed ascription of paternity to 32 of 85 offspring born among litters of 15 breeding females sampled. While the failure to unambiguously document paternity for all juveniles precludes the use of these data to address questions of sperm competition and male mating success, the results do provide direct evidence that multiple mating by female Richardsonā€™s Ground Squirrels results in multiple paternity within litters

    Family-Centered Early Intervention in North America: Have Home-based Programmes Lived up to their Promise for High-risk Families?

    Get PDF
    While early intervention programming is not new in North America, such programs have gone through a rapid expansion in recent years. This has been motivated by the recognition of the need for timely intervention, the development of a family rather than a child focused practice philosophy and the desire on the part of funding organizations to save money by promoting less expensive programming. This article reviews the various components of early intervention programmes in North America while also questioning aspects of current practice. There is a clear need for family-centered intervention. This should not be in question. However, the fundamental question should not be whether family centered intervention is necessary but rather how can empirical research inform best practices? It is the conclusion of the authors that this will be the key challenge in the coming years
