Survey Of Aquatic Invasive Species In Selected Umpqua National Forest Lakes And Ponds, Mark D. Sytsma, Rich Miller

Center for Lakes and Reservoirs Publications and Presentations

Eleven lakes and ponds within the Umpqua National Forest were surveyed for invasive aquatic macrophytes, snails, bivalves, and crayfish during the summer of 2011. Yellow floating heart (Nymphoides peltata), an invasive floating leaf macrophyte species, was detected in Willow Sump within the Little River drainage. European ear snails (Radix auricularia), an invasive species present in several Umpqua National Forest waterbodies, were detected in Beaver Pond within the Steamboat Creek drainage. One native crayfish species, the signal crayfish (Pacifastacus leniusculus), was observed in Crayfish Lake within the Brice Creek drainage. Diverse assemblages of native plant species were observed in the lakes …

Changing The Narrative Of Child Welfare, Matthew I. Fraidin

Georgetown Law Faculty Publications and Other Works

In child welfare, the difference we can make as lawyers for parents, children, and the state, and as judges, is to prevent children from entering foster care unnecessarily. And we can end a child’s stay in foster care as quickly as possible. To do that, we have to fight against a powerful narrative of child welfare and against the accepted “top-down” paradigm of legal services.

In this essay, Professor Fraidin suggests that we can achieve our goals of limiting entries to foster care and speeding exits from it by looking for the strengths of the people involved in our cases, …

Concrete Private Interest In Regulatory Enforcement: Tradable Environmental Resource Rights As A Basis For Standing, Danieli Evans

Articles

This Note proposes a novel solution to standing problems faced by environmental plaintifs seeking to enforce, or to compel agencies to enforce, environmental regulation. It argues that environmental plaintifs should be able to obtain standing to bring an Administrative Procedure Act (APA) review action or a citizen suit based on ownership of private tradable environmental resource rights, created by increasingly popular environmental privatization programs. These rights should operate as a basis for standing even for plaintifs who would otherwise be unable to meet standing requirements of individual injury, causation, and redressability. Relying on tradable rights to environmental resources as a …

Auditory Recall In Normal Children And Children With A Diagnosis Of Central Auditory Processing Disorder, Kara J. Nunziato

Theses and Dissertations

The purpose of this study was to investigate the differences in level of performance on auditory memory tasks between individuals with and without a diagnosis of Central Auditory Processing Disorder (CAPD). The study was also designed to examine the differences in performance among different auditory memory tasks. A total of ten participants were recruited for the study. Five typically developing individuals served in the control group and five individuals with a clinical diagnosis of CAPD served in the experimental group. Results from the study indicated that individuals with a diagnosis of CAPD performed significantly lower than the control group on …

Non-Traditional Distance Learners: Student Persistence In A Rural Remote Community, Paula Ann Sundet Wolf

Theses and Dissertations

Cook County Higher Education (CCHE), a non-profit distance education resource center located in rural northeastern Minnesota, has student completion rates of 90% and higher. CCHE has attributed the student persistence to its external support services, such as mentoring, technology support, study skills, attitude, and financial resources. With the national call for increased degrees per capita, there is also increased incentive for higher education institutions to become more creative in offering external support services to their non-traditional distance learning students. This grounded theory method research project explored rural students' perceptions of what motivates them to persist in distance learning programs. Thick, …

The Five-Factor Model As Predictor Of Performance On Decision-Making Tasks, Darci Van Dyke

Theses and Dissertations

Prior research on personality and decision-making has failed to use adequate measurement of both constructs. The current research extended the previous literature by incorporating multiple measures of decision-making as well as the NEO-PI-3, a psychometrically sound measure of the five-factor model of personality. Five measures of decision-making were used which addressed various aspects of adequate decision-making. The current research also included a measure of cognitive ability (WAIS-IV Vocabulary) as previous research has noted a strong correlation between cognitive ability and decision-making. Results indicated that cognitive ability significantly predicted performance on three decision-making tasks. In regard to personality, Agreeableness was the …

The Urotsa Bladder Cell Model For Heavy Metal Carcinogenesis: Characterization With Respect To The Role Of Beclin-1 And Sparc Expression, Jennifer Larson

Theses and Dissertations

The development of bladder cancer is known to have a strong association with environmental toxins. This laboratory employs the human Urotsa cell line model to explore the relationship between As+3 and Cd+2 exposure and the development of urothelial cancer.

The parental Urotsa cells and their As+3 and Cd+2 transformed counterparts have been used to define the mechanism of cell death (apoptosis and/or necrosis). A third mechanism of cell death, autophagy, has not yet been investigated. The hypothesis for the current study is that the autophagy pathway involving beclin-1plays a role in Urotsa cell death mechanisms. A combination of real time …

'Reel' Gangs Or 'Real' Gangs: A Qualitative Media Analysis Of Street Gangs Portrayed In Hollywood Films, 1960-2009, Christopher J. Przemieniecki

Theses and Dissertations

The purpose of this qualitative study is to explore the portrayals of street gangs as presented by a select sample of Hollywood films from 1960 to 2009. Using the theoretical framework of social constructionism and cinematic realism, a content analysis of 25 `street gang' films was conducted to (a) determine the comparability of depictions of street gangs in Hollywood films with those characteristics of defining a street gang in the law enforcement and academic literature, (b) identify emergent themes and patterns, including changes over time, and (c) address the representations of realism in the portrayal of street gangs as depicted …

Roles Of Ccaat/Enhancer-Binding Protein [Beta] And [-Delta] In Immunoglobulin G Immune Complex-Induced Inflammation, Chunguang Yan

Theses and Dissertations

CCAAT/enhancer-binding protein (C/EBP) &beta and C/EBP&delta are known to participate in the regulation of many genes associated with inflammation. However, little is known about the activation and function of C/EBP&beta and -&delta in inflammatory responses elicited by Fc&gamma receptor (Fc&gammaR) activation. Here I showed that C/EBP&beta and -&delta activation were induced in immunoglobulin G immune complex (IgG IC)-treated macrophages by using gel shift assays. The increased expression of C/EBP&beta and -&delta occurred at both mRNA and protein levels. Furthermore, induction of C/EBP&beta and -&delta was mediated, to a large extent, by activating Fc&gammaRs. Using small interfering RNA (siRNA)-mediated knockdown as …

Evaluation Of A Low Corrosion Method To Increase Mercury Oxidation And Scrubber Capture, Shuchita Sanjay Patwardhan

Theses and Dissertations

The taconite industry located in the Mesabi iron range has been identified as one of the major contributors of the atmospheric mercury in the Lake Superior basin by the Lake Superior Lakewide Management Plan (LaMP). Mercury is a leading concern among air toxic metals due to its volatility, persistence and bioaccumulation as methylmercury in the environment, and its neurological health impacts.

Previous research work performed at taconite processing plants by Minnesota Department of Natural Resources (DNR) identified the taconite ore as the main source of mercury during the taconite processing. Magentite iron ore pellets are produced by balling moist concentrates …

A Phenomenological Exploration Of The Childfree Choice In A Sample Of Australian Women, Joanne Doyle, Julie Ann Pooley, Lauren Breen

Research outputs 2012

Choosing not to have children is considered a deviation from cultural norms, particularly the dominant pronatalist discourse; this is especially so for women. However, little research has documented the experience of Australian women who have consciously chosen to remain childless. Ten voluntarily childfree women participated in unstructured interviews about their choice and its ramifications. The data analysis revealed three broad themes – the experiences and processes of making the choice; the ongoing effects of their choice, ranging from support and acceptance to pressure and discrimination; and no regret as the women described engaging in meaningful, generative activities that contributed to …

The Use Of Naltrexone In Pregnancy In Opiate-Dependent Mothers, Sadie Geraghty, Carly Dixon

Research outputs 2012

There is an absence of sufficient evidence regarding naltrexone use in pregnancy due to the limited range of human studies. Naltrexone implants are being used in Western Australia as a treatment for opioid dependency, and although contraindicated for insertion during pregnancy, there are a number of women who conceive while undergoing treatment. A review of the available data revealed that naltrexone is associated with improved maternal and fetal outcomes. Extensive research into this area in the form of large, multicentre trials is required to confirm the results of the current research.

Two Maximal Isometric Contractions Attenuate The Magnitude Of Eccentric Exercise-Induced Muscle Damage, Hsin-Lian Chen, Kazunori Nosaka, Alan Pearce, Trevor C Chen

Research outputs 2012

This study investigated whether maximal voluntary isometric contractions (MVC-ISO) would attenuate the magnitude of eccentric exercise-induced muscle damage. Young untrained men were placed into one of the two experimental groups or one control group (n = 13 per group). Subjects in the experimental groups performed either two or 10 MVC-ISO of the elbow flexors at a long muscle length (20° flexion) 2 days prior to 30 maximal isokinetic eccentric contractions of the elbow flexors. Subjects in the control group performed the eccentric contractions without MVC-ISO. No significant changes in maximal voluntary concentric contraction peak torque, peak torque angle, range of …

Role Of Food Availability In The Bathymetric Distribution Of The Starfish Marthasterias Glacialis (Lamk.)On Reefs Of Northern Portugal [Efecto De La Disponibilidad Alimenticia Sobre La Distribución Batimétrica De La Estrella De Mar Marthasterias Glacialis (Lamk.) En Arrecifes Del Norte De Portugal], Fernando Tuya, Pedro Duarte

Research outputs 2012

We examined whether the abundance and size of the starfish Marthasterias glacialis (Lamk.) exhibit a depth-dependent partitioning on subtidal reefs. We tested the hypothesis that differences in food availability can result in habitat partitioning along a depth gradient. The abundance and size of M. glacialis was registered at 4 depth strata: 0-4 m, 4-8 m, 8-12 m, and >12 m; we also recorded the number of food items that they were preying on. The abundance and size of M. glacialis decreased with depth. Mussels (Mytilus galloprivincialis) were the most preyed food item across all depth strata, followed by …

A Theory Of The Mind As A Complex System, Craig Speelman, Kim Kirsner, Stephan Halloy

Research outputs 2012

Five principles of skill acquisition are presented based on a review of research on human learning and expertise. Essentially these principles state that practice leads to faster and more efficient uses of knowledge. This enables faster performance and results in less demand on mental resources. In turn these outcomes enable higher level behaviours to be attempted. Ultimately skills are developed through refinement of many component processes. A theory of the mind is proposed that borrows from theories of complex adaptive systems. In this theory, the mind is conceived of as consisting of agents that compete for resources associated with processing …

Lsk Derived Lsk– Cells Have A High Apoptotic Rate Related To Survival Regulation Of Hematopoietic And Leukemic Stem Cells, Cong Peng, Yaoyu Chen, Yi Shan, Haojian Zhang, Zhiru Guo, Dongguang Li, Shaoguang Li

Research outputs 2012

A balanced pool of hematopoietic stem cells (HSCs) in bone marrow is tightly regulated, and this regulation is disturbed in hematopoietic malignancies such as chronic myeloid leukemia (CML). The underlying mechanisms are largely unknown. Here we show that the Lin⁻Sca-1⁺c-Kit^- (LSK⁻) cell population derived from HSC-containing Lin⁻Sca-1⁺c-Kit⁺ (LSK) cells has significantly higher numbers of apoptotic cells. Depletion of LSK cells by radiation or the cytotoxic chemical 5-fluorouracil results in an expansion of the LSK⁻ population. In contrast, the LSK⁻ population is reduced in CML mice, and …

Ethical Dilemmas During Mergers, Acquisitions And Takeovers, Edmond La Vertu, Llandis Barratt-Pugh

Research outputs 2012

The organisational world is still shaking from the impact of individual and organisational actions that are contrary to the open-ended community standards of ethics. Yet, ethical values have to fight continually for organisational space as the conflict between many differing corporate values problematises the workplace environment and decision-making for managers. This paper is based on a study that is investigating the relations between such values at times of significant organisational stress, when organisations merge, are acquired, or are taken-over, and the ethical dilemmas that arise from these events within the framework provided by Kidder (2009). The paper concludes by summarising …

Press Any Key: Repositioning Digital Literacy As An Enabler For Self-Regulated Learning, Joo Jung, Mark Mcmahon

Research outputs 2012

Millennial students are often seen as digital experts. This generalisation implicitly assumes that millennial students are equipped with necessary digital literacy skills to undertake their university learning such as searching curriculum-based information. But are they? And what is digital literacy and how can it be embed in teaching and learning? This paper examines the key characteristics of a contemporary view and multiplicity of digital literacy. An implementation of digital literacies in a first year undergraduate unit is described.

Learning In Transformational Computer Games: Exploring Design Principles For A Nanotechnology Game, Martin Masek, Karen Murcia, Jason Morrison, Christopher Newhouse, Mark Hackling

Research outputs 2012

Transformational games are digital computer and video applications purposefully designed to create engaging and immersive learning environments for delivering specified learning goals, outcomes and experiences. The virtual world of a transformational game becomes the social environment within which learning occurs as an outcome of the complex interaction of persons and digital resources. Engaging individuals with learning in these societal situations means concepts and skills are connected to the context and remain a powerful tool for decision making and problem solving in the world. Yet, a range of barriers need to be overcome to make a game effective for its educational …

Ethical Research In Indigenous Australian Contexts And Its Practical Implementation, Graeme Gower

Research outputs 2012

This paper is based on a three year longitudinal case study involving a number of Indigenous Australian communities in metropolitan, rural and remote settings. It will briefly discuss current ethical guidelines which have been developed by the National Health & Medical Research Council (NHMRC) for the conduct of research involving Indigenous Australian subjects (2003). These guidelines are in addition to the National Statement on ethical conduct in research involving humans (1999) and are aimed at incorporating values and principles of Aboriginal & Torres Strait Islander cultures in the conduct of research. In the case of Indigenous communities, research has historically …

Remembering Rhetoric: Recalling A Tradition Of Explicit Instruction In Writing, Brian Moon

Research outputs 2012

Modern secondary courses in English differ from classical tradition in their tendency to avoid direct instruction in the content and style of writing. Such avoidance is partly a function of anxieties about the role of English in students' personal development and a fear of limiting their self expression. Neither of the dominant writing pedagogies from the last 50 years wholly escapes this problem. A historical consideration of the issue suggests that fears surrounding explicit instruction arise from a range of misperceptions about writing and English. Modern writing pedagogy may therefore be improved by an acquaintance with traditions of explicit instruction, …

Impacts Of Urbanisation On The Native Avifauna Of Perth, Western Australia, Robert A. Davis, Cheryl Gole, J Dale Roberts

Research outputs 2013

Urban development either eliminates, or severely fragments, native vegetation, and therefore alters the distribution and abundance of species that depend on it for habitat. We assessed the impact of urban development on bird communities at 121 sites in and around Perth, Western Australia. Based on data from community surveys, at least 83 % of 65 landbirds were found to be dependent, in some way, on the presence of native vegetation. For three groups of species defined by specific patterns of habitat use (bushland birds), there were sufficient data to show that species occurrences declined as the landscape changed from variegated …

Evidence For A Non-Genomic Action Of Testosterone In Skeletal Muscle Which May Improve Athletic Performance: Implications For The Female Athlete, J R Dent, D K Fletcher, Michael Mcguigan

Research outputs 2012

This review will focus on the proposed second mode of testosterone action (now termed non-genomic) that appears to occur independently of the traditional transcriptional mechanism in mammalian skeletal muscle cells which may enhance skeletal muscle contractile properties. This mechanism of testosterone action differs from the traditional pathway, originating at the cell membrane, having a rapid onset of action, requiring second messengers to execute its effects and is insensitive to inhibitors of traditional androgen receptor action, transcription and protein synthesis. Importantly, unlike the traditional action of testosterone in skeletal muscle, this non-genomic pathway is shown to have a direct acute effect …

A Meta-Analysis Of Seaweed Impacts On Seagrasses: Generalities And Knowledge Gaps, Mads Thomsen, Thomas Wernberg, Aschwin H. Engelen, Fernando Tuya, Mat A. Vanderklift, Marianne Holmer, Karen J. Mcglathery, Francisco Arenas, Jonne Kotta, Brian R. Silliman

Research outputs 2012

Seagrasses are important habitat-formers and ecosystem engineers that are under threat from bloom-forming seaweeds. These seaweeds have been suggested to outcompete the seagrasses, particularly when facilitated by eutrophication, causing regime shifts where green meadows and clear waters are replaced with unstable sediments, turbid waters, hypoxia, and poor habitat conditions for fishes and invertebrates. Understanding the situations under which seaweeds impact seagrasses on local patch scales can help proactive management and prevent losses at greater scales. Here, we provide a quantitative review of available published manipulative experiments (all conducted at the patch-scale), to test which attributes of seaweeds and seagrasses (e.g., …

Assessing The Accessibility Of E-Learning, Morten Goodwin, Iain Sutherland, Frode Roarson, Tom Drange

Research outputs 2012

Equal participation for people with special needs is an important objective in education politics. Governments have a strong emphasis on enabling education for all citizens. The trend of using e-learning both for on campus and remote delivery of students has the potential of enabling new opportunities for people who previously faced challenges following education. On the other hand, providing online education bears the risk of creating new barriers. This paper examines different stages of providing educational content and delivering teaching material online. This is based on practical experiences from Noroff University College providing a bachelor degree in a security related …
