Disability And Accessibility In The Library And Information Science Literature: A Content Analysis, Heather Hill

Heather Hill

The library profession is often a strong and vocal proponent of increased access for persons with disabilities. With the profession's long-standing interest in the subject of services to persons with disabilities come questions that get to how the profession perceives the phenomenon. How is library and information science (LIS), as a field, conceptualizing disability and accessibility? The space for examining this question is a content analysis of the LIS literature. The literature provides a fertile ground for study as it reflects the profession's approaches to, and perceptions of, a topic. This research identifies the major issues and trends in the …

A New Species Of Euscorpius Thorell, 1876 From Peloponnese, Greece (Scorpiones: Euscorpiidae, Gioele Tropea, Victor Fet, Aristeidis Parmakelis, Panayiota Kotsakiozi, Iasmi Stathi

Victor Fet

A new scorpion species, Euscorpius (Euscorpius) erymanthius sp. n., is described from Peloponnese, Greece (Erymanthos Mts.), based on genetic and morphological evidence. It is characterized by small size, light brown to reddish color, and a standard trichobothrial pattern (Pv = 8–9, et = 7–6, em = 4 and eb = 4). In a phylogeny based on multiple DNA markers, the new species groups close with E. corcyraeus Tropea et Rossi, 2012 from Corfu (Kerkyra) Island.

Beyond Bivariate Correlations: Three-Block Partial Least Squares Illustrated With Vegetation, Soil, And Topography, Daehyun Kim, Thomas J. Dewitt, César S. B. Costa, John A. Kupfer, Ryan W. Mcewan, J. Anthony Stallins

Ryan McEwan

Ecologists, particularly those engaged in biogeomorphic studies, often seek to connect data from three or more domains. Using three-block partial least squares regression, we present a procedure to quantify and define bi-variance and tri-variance of data blocks related to plant communities, their soil parameters, and topography. Bi-variance indicates the total amount of covariation between these three domains taken in pairs, whereas tri-variance refers to the common variance shared by all domains. We characterized relationships among three domains (plant communities, soil properties, topography) for a salt marsh, four coastal dunes, and two temperate forests spanning several regions in the world. We …

Rapid Recovery Of A Coral Reef At Darwin Island, Galapagos Island, Peter W. Glynn, Bernhard Riegl, Adrienne M. S. Correa, Iliana B. Baums

Bernhard Riegl

Surveys at Darwin Island in 2006 and 2007 have demonstrated that this northernmost Galapagos Islands coral reef has recovered significantly since the 1982-3 El Nino event. When first surveyed in 1975, this structural reef exhibited actively accreting frameworks of pocilloporid and poritid corals. The coral suffered severe mortality in 1983, resulting in the near total loss of pocilloporids and extensive partial mortality of poritid corals. Large sections of the reef had not recovered by 1992 and dead frameworks were subject to bio-erosion, although small numbers of sexual recruits of pocilloporid corals and numerous recruits plus regenerating patches of Porites lobata …

Environmental Impacts Of Dredging And Other Sediment Disturbances On Corals: A Review, Paul. L. A. Erftemeijer, Bernhard Riegl, Bert W. Hoeksema, Peter A. Todd

Bernhard Riegl

A review of published literature on the sensitivity of corals to turbidity and sedimentation is presented, with an emphasis on the effects of dredging. The risks and severity of impact from dredging (and other sediment disturbances) on corals are primarily related to the intensity, duration and frequency of exposure to increased turbidity and sedimentation. The sensitivity of a coral reef to dredging impacts and its ability to recover depend on the antecedent ecological conditions of the reef, its resilience and the ambient conditions normally experienced. Effects of sediment stress have so far been investigated in 89 coral species (∼10% of …

Animal Minds, Cognitive Ethology, And Ethics, Colin Allen, Marc Bekoff

Marc Bekoff, PhD

Our goal in this paper is to provide enough of an account of the origins of cognitive ethology and the controversy surrounding it to help ethicists to gauge for themselves how to balance skepticism and credulity about animal minds when communicating with scientists. We believe that ethicists’ arguments would benefit from better understanding of the historical roots of ongoing controversies. It is not appropriate to treat some widely reported results in animal cognition as if their interpretations are a matter of scientific consensus. It is especially important to understand why loose references to ‘‘cognitive ethology’’ by philosophers can signal ignorance …

Agency In The Anthropocene: Goethe, Radical Reality, And The New Materialisms, Heather I. Sullivan

Heather I Sullivan

Our current era has been termed the Age of the “Anthropocene,” or the human- inflected geological era. This essay addresses the implications of human impact on the Earth as a form of “radical reality” by addressing the broad spectrum of human and non-human agency. The analysis follows a three-step process: it begins with an introduction to the new materialisms and distributed agency in contrast to Howard Tuttle’s notion of “radical reality” based on human consciousness. It then explores the agency of nature’s “vibrancy” in the debate occurring early in the Anthropocene (during Goethe’s lifetime) between “vitalism” and “mechanism.” Finally, I …

Microhabitat Use Affects Brain Size And Structure In Intertidal Gobies, Gemma E. White, Culum Brown

Culum Brown, PhD

The ecological cognition hypothesis poses that the brains and behaviours of individuals are largely shaped by the environments in which they live and the associated challenges they must overcome during their lives. Here we examine the effect of environmental complexity on relative brain size in 4 species of intertidal gobies from differing habitats. Two species were rock pool specialists that lived on spatially complex rocky shores, while the remainder lived on dynamic, but structurally simple, sandy shores. We found that rock pool-dwelling species had relatively larger brains and telencephalons in particular, while sand-dwelling species had a larger optic tectum and …

The Role Of The Primary School Principal In Developing Student Leadership, Gregory S.C. Hine, Shane D. Lavery

Gregory S.C. Hine

The development of student leadership potential is an important issue to investigate (Archard, 2009; Author, 2013; McNae, 2011). Yet to date, little research efforts have focussed on student leadership development programs within primary schools (K - 6). This research examined three aspects of student leadership within eight Catholic primary schools in metropolitan Perth, Western Australia. These aspects included the principals’ understanding of the term ‘student leadership’, their perception of the most appropriate form of student leadership in Catholic schools, and how they envisaged their role within a student leadership program. Qualitative data were collected through the exercise of semi-structured interviews …

Investigating Gastropod Habitat Associations In Saltmarsh, Joanne Green, Amanda J. Reichelt-Brushett, S Wl Jacobs

Associate Professor Amanda Reichelt-Brushett

Recent studies have provided new information on the taxonomy of gastropods snails in Australian saltmarsh but little is known of their ecology. For fauna colonisation to be used as a measure of the success of restoration or rehabilitation of degraded saltmarsh, a detailed understanding of the microhabitat associations of the target species in ‘reference’ locations across a range of latitudes is necessary. This study measured the densities of saltmarsh gastropods in two locations in northern New South Wales to determine microhabitat associations that could influence the results of rehabilitation assessment using fauna colonisation in Australian saltmarsh. In this study, Ophicardelus …

Accounting For Uncertainty In Ecological Analysis: The Strengths And Limitations Of Hierarchical Statistical Modeling, Noel Cressie, Catherine A. Calder, James S. Clark, Jay M. Ver Hoef, Christopher K. Wikle

Professor Noel Cressie

Analyses of ecological data should account for the uncertainty in the process(es) that generated the data. However, accounting for these uncertainties is a difficult task, since ecology is known for its complexity. Measurement and/or process errors are often the only sources of uncertainty modeled when addressing complex ecological problems, yet analyses should also account for uncertainty in sampling design, in model specification, in parameters governing the specified model, and in initial and boundary conditions. Only then can we be confident in the scientific inferences and forecasts made from an analysis. Probability and statistics provide a framework that accounts for multiple …

The Friesner Herbarium (But) Of Butler University, Rebecca Dolan

Rebecca W. Dolan

The Friesner Herbarium (BUT) of Butler University is a collection of over 100,000 specimens built from the personal herbarium of Ray C. Friesner. He and other botanists at Butler amassed one of the largest and most complete collections of Indiana plants. Active exchange from the 1920’s through the 1940’s increased the holdings of plants from other states. Although the collection does not contain many type specimens, it is rich in vouchers from floristic and ecological studies conducted in the first half of the 20th century and published in the scientific journal,Butler University Botanical Studies.

Changes In Orthodontic Treatment Modalities In The Past 20 Years: Exploring The Link Between Technology And Scientific Evidence, T. Gerard Bradley

T. Gerard Bradley

Statement of the issue: Is there a link between the many perceived advances in orthodontic techniques/therapy and science in the past 20 years? The purpose of this paper is to take five topics and match the perceptions with the scientific evidence. The variety of appliances and the swings in treatment philosophy have been dramatic, including the swing from extraction to non-extraction therapy, the introduction of space-age wires, appliances that grow mandibles, the introduction and extraordinary growth of Invisalign, and reduced friction brackets to reduce treatment time, all with claims by manufacturers of better results than ever before. The focus is …

Physiological And Genetic Correlates Of Boldness: Characterising The Mechanisms Of Behavioural Variation In Rainbow Trout, Oncorhynchus Mykiss, Jack S. Thomson, Phillip C. Watts, Tom G. Pottinger, Lynne U. Sneddon

Lynne Sneddon, PhD

Bold, risk-taking animals have previously been putatively linked with a proactive stress coping style whereas it is suggested shyer, risk-averse animals exhibit a reactive coping style. The aim of this study was to investigate whether differences in the expression of bold-type behaviour were evident within and between two lines of rainbow trout, Oncorhynchus mykiss, selectively bred for a low (LR) or high (HR) endocrine response to stress, and to link boldness and stress responsiveness with the expression of related candidate genes. Boldness was determined in individual fish over two trials by measuring the latency to approach a novel object. Differences …

Tb126: Vertical Trends In The Chemistry Of Forest Soil Microcosms Following Experimental Acidification, Ivan J. Fernandez

Ivan J. Fernandez

A soil microcosm experiment was conducted (a) to compare dilute H2SO4, NH4NO3 fertilizer, and prilled S as possible experimental soil-acidifying treatments and (b) to observe soil chemical response to simulated throughfall and acidifying treatments. Simulated throughfall had a significant effect on soil chemistry, resulting in increased exchangeable bases and pH in the mineral soil horizons but little effect on the O horizon. Of the acidification treatments only simulated acid rain had significant effects on soil chemistry when compared to the control and the dry treatments. This reflected the relatively slow dissolution rate of the dry treatments coupled with the short …

An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson

Philip J. Nyhus

Human-caused biodiversity loss is a global problem, large carnivores are particularly threatened, and the tiger (Panthera tigris) is among the world’s most endangered large carnivores. The South China tiger (Panthera tigris amoyensis) is the most critically endangered tiger subspecies and is considered functionally extinct in the wild. The government of China has expressed its intent to reintroduce a small population of South China tigers into a portion of their historic range as part of a larger goal to recover wild tiger populations in China. This would be the world’s first major tiger reintroduction program. A free-ranging population of 15–20 tigers …

Why You Should Care About The Threatened Middle Class, Jill Littrell, Fred Brooks, Jan Ivery, Mary Ohmer

jill l littrell Dr.

In the last two decades, the income and security of the individual middle class worker has declined and the gap between the middle class and the wealthy has widened. We explain how this is bad for democracy, the economy, and the aggregate health of the nation. We examine the governmental policies and interventions that increased the middle class following the depression and maintained its vigor through the post-World War II period. The impetus for these changes in governmental policies in the 1930s was to end the Great Depression. We pose the question of whether a nation can recover from a …

Health Professionals’ Roles In Animal Agriculture, Climate Change, And Human Health, Aysha Z. Akhtar, Michael Greger, Hope Ferdowsian, Erica Frank

Michael Greger, MD, FACLM

What we eat is rapidly becoming an issue of global concern. With food shortages, the rise in chronic disease, and global warming, the impact of our dietary choices seems more relevant today than ever. Globally, a transition is taking place toward greater consumption of foods of animal origin, in lieu of plantbased diets. With this transition comes intensification of animal agriculture that in turn is associated with the emergence of zoonotic infectious diseases, environmental degradation, and the epidemics of chronic disease and obesity. Health professionals should be aware of these trends and consider them as they promote healthier and more …

What Can We Learn From Confusing Olivella Columellaris And O. Semistriata (Olivellidae, Gastropoda), Two Key Species In Panamic Sandy Beach Ecosystems?, Allison I. Troost, Samantha D. Rupert, Ariel Z. Cyrus, Frank V. Paladino, Benjamin F. Dattilo, Winfried S. Peters

Benjamin F. Dattilo

Olivella columellaris (Sowerby 1825) and O. semistriata (Gray 1839) are suspension-feeding, swash-surfing snails on tropical sandy beaches of the east Pacific. While they often are the numerically dominant macrofaunal element in their habitats, their biology is poorly understood; the two species actually have been confused in all of the few publications that address their ecology. Frequent misidentifications in publications and collections contributed also to an overestimation of the geographic overlap of the two species. To provide a sound taxonomic basis for further functional, ecological, and evolutionary investigations, we evaluated the validity of diagnostic traits in wild populations and museum collections, …
