Walking The Talk On Sustainable Development Goals: The Case Of Community Foundations In Canada, Marta Rey-Garcia, Rosane Dal Magro

The Foundation Review

The United Nations 2030 Agenda creates an opportunity for philanthropic foundations to become more collaborative and transformative in their work toward global goals. Thus, since 2016, the extent to which foundations adopt the Sustainable Development Goals framework in their functioning has become a topic of interest. Although survey- and case-based research shows increased rates of self-reported adoption and several tools are available to help foundations to act toward the goals, there is a lack of systematic evidence about the purposes of and processes for adopting the goals among foundations.

This void is particularly relevant for community foundations, as they have …

Proof Positive: Applications Of Chemical Analysis Techniques In Art Forgery Detection, Joseph Fryc

Museum Studies Theses

In response to the subjective nature of older forgery detection techniques, modern forgery detection methods rely heavily on chemical analysis of the materials utilized in a given piece of work in order to make authenticity determinations. Chemical methods of detection at their core provide an objective determination of facts regarding the composition of materials utilized in contested pieces and provide a relative date of production for those materials. In this way, chemical analysis helps service the field of modern forgery detection as a direct compliment to traditional stylistic analysis, by providing extra data on the piece that can often be …

All Peer-Reviewed Publications

On a global scale, invasive grasses threaten biodiversity and ecosystem function. Nevertheless, the importation of forage grasses is a significant economic force driven by globalization. Pastureland and rangeland are of critical economic and ecological importance, but novel grass species may lead to invasion. Recognizing that economically important species can also be ecologically damaging creates a contentious debate for land managers, policymakers, and ecologists alike. Many Afrotropical perennial grass species have been intentionally introduced pantropically given their high forage production and resistance to stress. However, these traits may also confer competitive ability, increasing the possibility of unintended escape and invasion. Further, …

Root Exudate Chemical Cues Of An Invasive Plant Modulate Oviposition Behavior And Survivorship Of A Malaria Mosquito Vector, Trizah K. Milugo, David P. Tchouassi, Reginald A. Kavishe, Rhoel R. Dinglasan, Baldwyn Torto

All Peer-Reviewed Publications

Gravid female Anopheles gambiae mosquitoes identify suitable oviposition sites through a repertoire of cues, but the influence of allelochemicals, especially root phytochemicals in modulating this behavior and impacting subsequent progeny bionomics remains unexplored. We addressed these questions in the malaria vector Anopheles gambiae and its invasive host plant Parthenium hysterophorus. Using chemical analysis combined with laboratory behavioral assays, we demonstrate that a blend of terpenes, namely α-pinene, α-phellandrene, β-phellandrene, 3-carene and (E)-caryophyllene emitted from P. hysterophorus root exudate treated-water attracted gravid females. However, fewer eggs (55%) hatched in this treatment than in control water (66%). The sesquiterpene lactone parthenin, identified …

Exegesis: Mark 6:30-44, Younggwang Kim

Masters Theses

Jesus’ feeding the five thousand is the only miracle that the four Gospels commonly recorded among the miracles Jesus Himself performed. The feeding miracle episode is like the gem, which changes light colors slightly depending on how people see it. However, some scholars try to approach it only in a particular direction and partially understand it. Based on the literary-historical-theological methodology, this thesis has a focal point to disclose the compressive and multi-dimensional implications. The exegesis of Mark 6:30-44 begins with the refinement of interpretive methodology. The methodology of this thesis prudently considers both the traditional perspective and recent research. …

Serving Special Education Students In The Music Classroom: Accommodating And Advocating For Learners With Exceptionalities, Kathryn Lambert

Masters Theses

Music education programs positively impact the lives of students both socially and emotionally. As the following research suggests, music may have an even greater impact on students with disabilities or exceptionalities. Due to the lack of accessibility, funding, time, training, and other issues, opportunities in music education programs may be limited to groups of students who may not fit the standard music education student profile. As teachers of common core classes may struggle to accommodate students with exceptionalities and may feel as if they are lacking in resources or other needed preparation to adequately serve these students, these struggles are …

Eldre65: Creating A Website For Senior Adults Based Upon User Experience, Rebecca Joy Bozarth

Masters Theses

Geoffrey Chaucer wrote, “Time and tide wait for no man.” He was correct. Aging is universal. It affects all humans in positive and negative ways. From children becoming teens to adults becoming senior adults, each stage of life brings changes and challenges. In one’s forties, menus can become harder to read, hair can fall out, hearing in loud environments can become difficult. Then, in one’s mid-sixties, more difficult challenges can arrive. Health issues such as high blood pressure, diabetes, lung disease can become a regular part of one’s life. Cognition slowness, vision and hearing loss can create difficulties not only …
