Oregon Capital Scan: A Line is Drawn

This report was written with the primary intention of helping to educate entrepreneurs and growth company leaders with respect to the variety and scale of capital sources currently available in the State. It is not uncommon for those seeking to enter the capital markets as an entrepreneur to possess a limited understanding of where capital can be found. This knowledge gap leads to a level of perceived risk uncertainty that inhibits company formation and growth. This report is not intended to instruct entrepreneurs in the skills required to secure funding, rather it is intended as a catalog of source data to enlighten as to the many different types of capital available. This report is also intended for policy makers and those who work to support the development of a thriving growth company ecosystem in the State. This includes the sponsors of this report who seek to find new ways to bring together education and resources to enhance the ability of those who choose to build their companies in Oregon. This report can serve as a baseline of quantitative data that may help everyone to better understand where we are as a State now, with respect to the key ingredient of growth capital, and help us measure our progress and improvements over time

Fan-Linear Maps and Fan Algebras

Fan algebras arise from fan-linear maps, a special class of functions defined on partitions of the nonnegative integer lattice in the plane. These algebras are natural objects of study in commutative algebra as they include many classical examples of commutative rings. Additionally, the ubiquity of this structure has only recently been identified, therefore little is known regarding the properties of these algebras. We begin our study by classifying all fan-linear maps via the conditions imposed on them by their domains. This classification includes a general result regarding the universal group of cones in lattices of arbitrary dimension. We then go on to show that the set of all fan-linear maps on any fixed partition is necessarily a finitely-generated affine semigroup. Finally, this leads to the conclusion that the set of fan algebras corresponding to a fixed partition and a fixed set of ideals forms a finitely generated semigroup. This is accomplished through the identification of generating maps in the semigroup of all fan-linear maps with generating algebras and the description of a natural additive operation

Perceptions of Sexual Violence in Dating Relationships: Presentation Medium and Couple Characteristics

Undergraduate students evaluated scenarios depicting violence in a long-term dating relationship—in either video or written form, and involving either a male or female aggressor in either a same- or other-gender relationship. Other than the genders of the victims and assailants, the details of the scenarios were identical. Results showed that participants rated written scenarios as more powerful than video scenarios and believed that sexual assault was more likely to have happened in the written than in the video scenarios. Compared to men, women were more emotionally impacted by the scenarios, thought sexual assault was more likely to have happened, were more likely to think the aggressor wanted to have sex with the victim, and were less likely to think the victim wanted to have sex with the aggressor. Participants who rated other-sex scenarios thought sexual assault was more likely to have occurred, that the aggressor more likely wanted to have sex with the victim, and that the victim less likely wanted to have sex with the aggressor than those rating same-sex scenarios. When women were portrayed as the victims, regardless of relationship type, the scenario was more emotionally evocative. On average, participants strongly agreed that sexual assault had occurred in each of the scenarios

Framing a New Standard for Teaching in Alberta

A research panel asked to frame the discussion for a new Teaching Quality Standard in Alberta assumes this task requires a paradigm shift away from the status quo efficiency movement. As a member of the panel, the author provides an analysis of paradigm shifts in education and recounts important lessons to be learned. The author challenges the notion that the alternative paradigm posed by an emerging knowledge society provides the best framework to define quality teaching. To accentuate the centrality of relationships, the author offers culture-making as a preferred paradigm where who teachers are is valued as much as what teachers do. Un groupe de recherche à qui on a demandé de délimiter une discussion sur une nouvelle norme pour la qualité de l’enseignement en Alberta part du principe que la tâche exige que l’on délaisse le mouvement actuel prônant l’efficacité. L’auteur, membre de ce groupe de recherche, analyse les changements de paradigme en éducation et rappelle les leçons importantes à tirer de cette évolution. L’auteur conteste la notion que le paradigme alternatif que pose la société de la connaissance émergeante constitue la meilleure base sur laquelle axer l’enseignement de qualité. Il propose plutôt un paradigme reposant sur la création de la culture selon lequel les enseignants sont appréciés pour ce qu’ils sont autant que pour ce qu’ils font

Subfield-Compatible Polynomials over Finite Fields

Polynomial functions over finite fields are important in computer science and electrical engineering in that they present a mathematical representation of arithmetic circuits. This paper establishes necessary and sufficient conditions for polynomial functions with coefficients in a finite field and naturally restricted degrees to be compatible with given subfields. Most importantly, this is done for the case where the domain and codomain fields have differing cardinalities. These conditions, which are presented for polynomial rings in one and several variables, are developed via a universal permutation that depends only on the cardinalities of the given fields

Microstegium vimineum Spread Rate in Relation to Two Different Leaf Litter Disturbances and an Evaluation of Aboveground Biomass Accumulation and Photosynthetic Efficiency in Response to Four Light Treatments

Microstegium vimineum is a non-native invasive plant species classified as an annual, shade-tolerant C4 grass. There is limited research regarding variables affecting the spread of M. vimineum. Two studies were conducted to investigate the spread of M. vimineum. A field study was undertaken in 2009 to determine how M. vimineum spreads in relation to litter disturbance. In 2010, a greenhouse study was conducted to determine the impact light has on M. vimineum aboveground biomass, height growth, and photosynthetic efficiency. The field study consisted of three treatments, Undisturbed (Control), Stirring, and Removal of leaf litter, employed along the boundary of existing M. vimineum populations in ½-meter by 2-meter plots. Distance of spread from the existing population and percent cover were documented for one growing season. Plants were counted at the end of the study. Neither stirring nor removal of leaf litter had a significant impact on spread rate, percent cover, or the number of plants in a given treatment suggesting pre-growing season leaf litter disturbance does not influence M. vimineum spread, percent cover, or number of plants. The greenhouse study consisted of growing M. vimineum under four light treatments: 100, 70, 45, and 20 percent of full light. Heights were measured weekly while minimum, maximum, and variable fluorescence emission, non-photochemical and photochemical quenching, and maximum quantum yield of Photosystem II photochemistry (QYmax) were measured every 10 days. Aboveground biomass accumulation was calculated at the end of the study. Results indicate that M. viminuem aboveground biomass accumulation is highest in 70 percent to 100 percent light while photosynthetic efficiency is highest between 45 percent and 70 percent light. This research indicates that M. vimineum does not spread appreciably at low light levels (closed canopies) in areas with litter disturbances that do not change the light regime. M. vimineum has greater aboveground biomass and photosynthetic efficiencies at higher levels of light. Thus, forest disturbances that result in more light reaching the ground may influence the spread of M. vimineum by creating a more favorable environment
