Professor Martin Milkeco_mimman in the Economics and Finance department at Murray State University is this week’s #RacerScholar. His article, “Writing Across the Curriculum in Elective Economics Classes,” is included in volume 46, issue 1, of National Social Science Journal.

Abstract

This paper presents the methods and results of a Writing Across the Curriculum (WAC) study conducted at Murray State University in two elective economics classes. While there is plenty of literature about WAC, I hope that this paper will be interesting as it offers some suggestions to instructors who would be interested using WAC in their classrooms. After a very brief review of the literature, the paper describes how WAC was used in the two classes and the results of the program.

mmb_roaAlexander Rose, Ph.D., Assistant Professor of Marketing, at Murray State University is this week’s #RacerScholar. He co-authored to the article, “Mutuality: Critique and substitute for Belk’s “sharing”,’ which was published in the March 2016 edition of Marketing Theory.

 

 

Abstract

The recently introduced construct of consumer sharing is represented as a nonreciprocal, pro-social distribution of resources given without expectation of reciprocity (Belk, 2010, Sharing’, Journal of Consumer Research 36: 715-34). The approach adopted rests on shaky ontological and epistemological grounds and reproduces an array of problematic modernist dichotomies (e.g., agency/structure, nurturing family/instrumental public, gift/market, and altruism/self-interest) that significantly constrain the analytical enterprise. This work redresses some of the conceptual problems in the current formulation. The critique highlights a focus on resource distribution based on a more holistic, socially grounded perspective on circulation. We offer the alternative concept of mutuality or generalized exchange and the metaphor of inclusion rather than exchange as central to this perspective. We argue this may provide a more sound basis for understanding alternative modes of circulation.

Paul R. Gagnon, Ph.D. is this week’s #RacerScholar

prgagnonheadnshoulders_1Professor Gagnon is this week’s #RacerScholar for contributing to the article, “How livestock and flooding mediate the ecological integrity of working forests in Amazon River floodplains,” in the January 2016 edition of Ecological Applications.

Abstract:

The contribution of working forests to tropical conservation and
development depends upon the maintenance of ecological integrity under
ongoing land use. Assessment of ecological integrity requires an
understanding of the structure, composition, and function and major
drivers that govern their variability. Working forests in tropical river
floodplains provide many goods and services, yet the data on the
ecological processes that sustain these services is scant. In flooded
forests of riverside Amazonian communities, we established 46 0.1-ha
plots varying in flood duration, use by cattle and water buffalo, and
time since agricultural abandonment (30-90 yr). We monitored three
aspects of ecological integrity (stand structure, species composition,
and dynamics of trees and seedlings) to evaluate the impacts of
different trajectories of livestock activity (alleviation, stasis, and
intensification) over nine years. Negative effects of livestock
intensification were solely evident in the forest understory, and plots
alleviated from past heavy disturbance increased in seedling density but
had higher abundance of thorny species than plots maintaining low
activity. Stand structure, dynamics, and tree species composition were
strongly influenced by the natural pulse of seasonal floods, such that
the defining characteristics of integrity were dependent upon flood
duration (3-200 d). Forests with prolonged floods >= 140 d had not only
lower species richness but also lower rates of recruitment and species
turnover relative to forests with short floods < 70 d. Overall, the
combined effects of livestock intensification and prolonged flooding
hindered forest regeneration, but overall forest integrity was largely
related to the hydrological regime and age. Given this disjunction
between factors mediating canopy and understory integrity, we present a
subset of metrics for regeneration and recruitment to distinguish forest
condition by livestock trajectory. Although our study design includes
confounded factors that preclude a definitive assessment of the major
drivers of ecological change, we provide much-needed data on the
regrowth of a critical but poorly studied ecosystem. In addition to its
emphasis on the dynamics of tropical wetland forests undergoing
anthropogenic and environmental change, our case study is an important
example for how to assess of ecological integrity in working forests of
tropical ecosystems.

Research and Instruction Librarians Elizabeth Price and Rebecca Richardson are this week’s #RacerScholars. Their paper, “Integrating the thematic approach into information literacy courses,” was published in the February 2015 edition of Reference Services Review, an Emerald publication.

 

Abstract:

Purpose – The purpose of this paper is to review selected publications in library-related literature and discuss the thematic approach to course design in colleges and universities and how it has been implemented into information literacy (IL) courses.

Design/methodology/approach – A literature review of peer-reviewed journals, professional journals, magazines and blogs contextualizes the thematic approach to instruction at the college and university levels. Search terms included “thematic approach”, “thematic approach in education” and “theme-based instruction”; the search was restricted to articles published in the past 20 years. Findings – In addition to the IL courses, thematic-based instruction has been used in biology, chemistry, English, French literature, history, mathematics, philosophy and sociology courses in college and university campuses. While instructors report that the thematic approach enhances student learning, few studies have directly tested the impact. No studies have been published within the library science literature.

Originality/value – Thematic approach is a newer concept in the world of IL instruction. While many professional journal articles and blog posts provide in-depth case studies of how thematic-based instruction has been implemented, this article draws from all disciplines and features a succinct summary of what works, what does not work and how to best implement a thematic approach in an IL course.

Professor Laura Liljequist in the Department of Psychology at Murray State University is this week’s #RacerScholar. She co-authored the article, “Determining the Accuracy of Self-Report Versus Informant-Report Using the Conners’ Adult ADHD Rating Scale,” which appeared in the April 2016 issue of Journal of Attention Disorders.

Abstract

Objective: The present research examined the validity of self-report versus informant-report in relation to a performance-based indicator of adult ADHD.

Method: Archival data from 118 participants (52 males, 66 females) were used to compare Conners’ Adult ADHD Rating Scale–Self-Report: Long Format (CAARS-S:L) and Conners’ Adult ADHD Rating Scale–Observer Report: Long Format (CAARS-O:L) with discrepancy scores calculated between the Wechsler Adult Intelligence Scale–Third Edition (WAIS-III) Verbal Comprehension Index – Working Memory Index (VCI – WMI) and Perceptual-Organizational Index – Processing Speed Index (POI – PSI) scaled scores.

Results: Neither the self- nor informant-report formats of the CAARS were better predictors of discrepancies between WAIS-III Index scores. Intercorrelations between the CAARS-S:L and CAARS-O:L revealed generally higher correlations between the same scales of different formats and among scales measuring externally visible symptoms. Furthermore, regression analysis indicated that both the CAARS-S:L and CAARS-O:L clinical scales contributed a significant proportion of variance in WAIS-III VCI – WMI discrepancy scores (14.7% and 16.4%, respectively). Conclusion: Results did not establish greater accuracy of self-report versus informant-report of ADHD symptomatology, rather demonstrate the need for multimodal assessment of ADHD in adults.

 Abstract

Cannibalism is widespread in size-structured populations. If cannibals and victims are in different life stages, dominant cohorts of cannibals can regulate recruitment. Arizona Tiger Salamanders, Ambystoma tigrinum nebulosum, exhibit facultative paedomorphosis in which salamander larvae either metamorphose into terrestrial adults or become sexually mature while still in their larval form. Although many salamanders exhibit cannibalism of larvae, the Arizona Tiger Salamander also exhibits cannibalism of young by the aquatic adults. We formulate a differential equations model of this system under the assumption that the terrestrial adults do not impact the system beyond their contribution to the birth of young larvae. We establish non-negativity, boundedness and persistence of the salamander population under certain assumptions. We consider the equilibrium states of the system in the presence or absence of a birth contribution from the terrestrial or metamorph adults. Constant per capita paedomorphosis leads to asymptotically stable equilibria. The per capita paedomorphosis rate of the larvae must be density dependent in order for periodic solutions to exist. Furthermore, the stage transition rate must be sufficiently decreasing in order to guarantee the existence of an unstable equilibrium. Periodic solutions are only possible in the presence of a unique nontrivial unstable equilibrium. Our results conform to previous theory on paedomorphosis which suggests general applicability of our results to similar systems.

Abstract

This study examined the concerns of regular elementary school teachers in Gurgaon, India, in order to work with students with disabilities in inclusive education settings. A total of 175 teachers responded to a two-part questionnaire. Data were analyzed using descriptive and inferential statistics. The data indicated that the teachers in Gurgaon, overall, were a little concerned about implementing inclusive education in their schools. Significant difference existed in teacher concerns whether they taught in government versus privately managed schools. Implications are discussed to address teacher concerns for inclusive education in India.

The paper he contributed to, “Benchmarking Optical/Thermal Satellite Imagery for Estimating Evapotranspiration and Soil Moisture in Decision Support Tools,” appeared in the February 2016 issue of the Journal of the American Water Resources Association.

Abstract

Generally, one expects evapotranspiration (ET) maps derived from optical/thermal Landsat and MODIS satellite imagery to improve decision support tools and lead to superior decisions regarding water resources management. However, there is lack of supportive evidence to accept or reject this expectation. We benchmark three existing hydrologic decision support tools with the following benchmarks: annual ET for the ET Toolbox developed by the United States Bureau of Reclamation, predicted rainfall-runoff hydrographs for the Gridded Surface/Subsurface Hydrologic Analysis model developed by the U.S. Army Corps of Engineers, and the average annual groundwater recharge for the Distributed Parameter Watershed Model used by Daniel B. Stephens & Associates. The conclusion of this benchmark study is that the use of NASA/USGS optical/thermal satellite imagery can considerably improve hydrologic decision support tools compared to their traditional implementations. The benefits of improved decision making, resulting from more accurate results of hydrologic support systems using optical/thermal satellite imagery, should substantially exceed the costs for acquiring such imagery and implementing the remote sensing algorithms. In fact, the value of reduced error in estimating average annual groundwater recharge in the San Gabriel Mountains, California alone, in terms of value of water, may be as large as $1 billion, more than sufficient to pay for one new Landsat satellite.

Mike Bordieri, Ph.D. contributed to the paper, “Basic Properties of Coherence: Testing a Core Assumption of Relational Frame Theory,” which appears in the March 2016 issue of Psychological Record.

Abstract

Introduction
Relational frame theory contains a foundational assumption that coherence (i.e., making sense) is reinforcing for verbally competent humans. That is, it is assumed that humans relate ambiguous stimuli together because they have an extensive learning history where doing so resulted in both effective environmental action and socially mediated reinforcement (e.g., praise, positive attention).

Methods
This investigation tested this core assumption of relational frame theory by analyzing response patterns to ambiguous stimuli in a matching-to-sample task (Study 1) and by assessing whether participants displayed a preference toward coherent contexts in a concurrent chains preparation (Study 2).

Results
The majority of participants responded to ambiguous stimuli in ways that were internally consistent and congruent with their previous learning histories in the absence of any programmed contingencies. Many participants also displayed a preference toward contexts where coherent responding was possible, and there was a trend toward switching away in preference when it became increasingly costly to access the coherent context.

Discussion
The major theoretical contributions of these findings are discussed.

‘Internal Medicine: a Doctor’s Stories’ is our #NewBookoftheWeek

Internal Medicine pbk.inddOur #NewBookoftheWeek is Terrence Holt’s Internal Medicine: A Doctor’s Stories. You can find the book on the “New Book Shelf” in Waterfield Library.

Summary

In this “artful, unfailingly human, and understandable” (Boston Globe) account inspired by his own experiences becoming a doctor, Terrence Holt puts readers on the front lines of the harrowing crucible of a medical residency. A medical classic in the making, hailed by critics as capturing “the feelings of a young doctor’s three-year hospital residency . . . better than anything else I have ever read” (Susan Okie, Washington Post), Holt brings a writer’s touch and a doctor’s eye to nine unforgettable stories where the intricacies of modern medicine confront the mysteries of the human spirit. Internal Medicine captures the “stark moments of success and failure, pride and shame, courage and cowardice, self-reflection and obtuse blindness that mark the years of clinical training” (Jerome Groopman, New York Review of Books), portraying not only a doctor’s struggle with sickness and suffering but also the fears and frailties each of us—doctor and patient—bring to the bedside. —W.

Abstract

A series of 1-alkyl-3-methyl-1,2,3-triazolium bis(trifluoromethylsulfonyl)imide [NTf2] ionic liquids were prepared synthetically using azide–alkyne ‘click’ cyclization chemistry and their physicochemical and thermal properties were determined. Increasing the alkyl chain length resulted in increased viscosities and higher thermal transitions (Tg or Tm) with depressed molar conductivities. Walden plot analysis indicated that the ionicity of 1-butyl-3-methyl-1,2,3-triazolium [NTf2] was comparable to the analogous imidazolium system and higher than the 1,2,4-triazolium equivalent.

This article was published in volume 52, issue 1 of In Vitro Cellular & Developmental Biology – Animal.

Abstract

We have investigated the role chondroitin sulfate has on cell interactions during neural plate formation in the early chick embryo. Using tissue culture isolates from the prospective neural plate, we have measured neural gene expression profiles associated with neural stem cell differentiation. Removal of chondroitin sulfate from stage 4 neural plate tissue leads to altered associations of N-cadherin-positive neural progenitors and causes changes in the normal sequence of neural marker gene expression. Absence of chondroitin sulfate in the neural plate leads to reduced Sox2 expression and is accompanied by an increase in the expression of anterior markers of neural regionalization. Results obtained in this study suggest that the presence of chondroitin sulfate in the anterior chick embryo is instrumental in maintaining cells in the neural precursor state.

Abstract

Cueva Victoria has provided remains of more than 90 species of fossil vertebrates, including a hominin phalanx, and the only specimens of the African cercopithecid Theropithecus oswaldi in Europe. To constrain the age of the vertebrate remains we used paleomagnetism, vertebrate biostratigraphy and Th-230/U dating. Normal polarity was identified in the non-fossiliferous lowest and highest stratigraphic units (red clay and capping flowstones) while reverse polarity was found in the intermediate strati graphic unit (fossiliferous breccia). A lower polarity change occurred during the deposition of the decalcification clay, when the cave was closed and karstification was active. A second polarity change occurred during the capping flowstone formation, when the upper galleries were filled with breccia. The mammal association indicates a post-Jaramillo age, which allows us to correlate this upper reversal with the Brunhes-Matuyama boundary (0.78 Ma). Consequently, the lower reversal (N-R) is interpreted as the end of the Jaramillo magnetochron (0.99 Ma). These ages bracket the age of the fossiliferous breccia between 0.99 and 0.78 Ma, suggesting that the capping flowstone was formed during the wet Marine Isotopic Stage 19, which includes the Brunhes-Matuyama boundary. Fossil remains of Theropithecus have been only found in situ similar to 1 m below the B/M boundary, which allows us to place the arrival of Theropithecus to Cueva Victoria at similar to 0.9-0.85 Ma. The fauna of Cueva Victoria lived during a period of important climatic change, known as the Early-Middle Pleistocene Climatic Transition. The occurrence of the oldest European Acheulean tools at the contemporaneous nearby site of Cueva Negra suggest an African dispersal into SE Iberia through the Strait of Gibraltar during MIS 22, when sea-level was 100 m below its present position, allowing the passage into Europe of, at least, Theropithecus and Homo bearing Acheulean technology.

flinnOur #RacerScholar this week is Professor Michael B. Flinn in the Department of Biology. He contributed to the article, “Baseflow physical characteristics differ at multiple spatial scales in stream networks across diverse biomes,” which appeared in volume 31, issue 1 of Landscape Ecology.

Abstract

Context
Spatial scaling of ecological processes is facilitated by quantifying underlying habitat attributes. Physical and ecological patterns are often measured at disparate spatial scales limiting our ability to quantify ecological processes at broader spatial scales using physical attributes.

Objective
We characterized variation of physical stream attributes during periods of high biological activity (i.e., baseflow) to match physical and ecological measurements and to identify the spatial scales exhibiting and predicting heterogeneity.

Methods
We measured canopy cover, wetted width, water depth, and sediment size along transects of 1st-5th order reaches in five stream networks located in biomes from tropical forest to arctic tundra. We used hierarchical analysis of variance with three nested scales (watersheds, stream orders, reaches) to identify scales exhibiting significant heterogeneity in attributes and regression analyses to characterize gradients within and across stream networks.

Results
Heterogeneity was evident at one or multiple spatial scales: canopy cover and water depth varied significantly at all three spatial scales while wetted width varied at two scales (stream order and reach) and sediment size remained largely unexplained. Similarly, prediction by drainage area depended on the attribute considered: depending on the watershed, increases in wetted width and water depth with drainage area were best fit with a linear, logarithmic, or power function. Variation in sediment size was independent of drainage area.

Conclusions
The scaling of ecologically relevant baseflow physical characteristics will require study beyond the traditional bankfull geomorphology since predictions of baseflow physical attributes by drainage area were not always best explained by geomorphic power laws.

Abstract

We consider the impact of the Brazilian crisis of 1999 on the extensive and intensive margin of exporters versus non-exporters through the open economy balance sheet channel. Using an open economy balance sheet channel model with firm heterogeneity, we explore predictors that firms will engage in global markets. Our results based on a detailed firm-level panel of data for Brazilian 10,573 firms for the period 1996–2007, show that the decision to export and overall growth of sales for exporting firms is driven by size, the debt ratio, the current ratio and operating costs as well as the direct impact of the crisis itself. The findings suggest that the mechanism is driven by the response of the credit market to the creditworthiness of firms as it is by changing terms of trade.

Abstract

The aim of this interpretive study was to examine the perceptions and beliefs of general education teachers in Delhi, India, about the inclusion of students with disabilities (SWDs) in regular education classrooms. In this study, with hermeneutic phenomenology as its methodological framework, 15 semi-structured interviews of public school teachers in Delhi were conducted. Each interview, lasting from 30 to 45 min, was recorded and transcribed. The data were analyzed using a constant comparative method. The following conclusions were drawn: (1) Sociocultural ideologies on disability have affected the education of SWDs, and (2) systematic institutional barriers have led teachers to accept inclusion only “in theory.”

Abstract

In this article we introduce the Internet of Things to the broad managerial community and explore one of its central tensions: convenience vs. privacy and secrecy. We clarify the ways in which IoT differs from Web 2.0 and then highlight opportunities, challenges, and managerial guidance. In addition, we explore the prominent issue of privacy and secrecy. Due to substantial increases in amounts of consumer-related data and their accessibility as well as potential tradeoffs in benefits associated with IoT and in properties of humanness associated with the consumer experience, the managerial issue of privacy is elevated to a level never before realized—perhaps on par with, or worthy of inclusion as an element of, the classic marketing mix.

home_coverProfessor Laura Liljequist in the Department of Psychology at Murray State University is this week’s #RacerScholar. She co-authored the article, “Specificity of the CAARS in Discriminating ADHD Symptoms in Adults From Other Axis I Symptoms,” which appeared in a special issue on the Assesment of ADHD in the Journal of Attention Disorders.

Abstract

Objective: In this study, we examined the sensitivity and specificity of the Conners’ Adult ADHD Rating Scale-Self-Report: Long Version (CAARS) in 113 adult clinical archival records.

Method: Forty-five clients had requested evaluation for ADHD, suggesting problems with attention, and 68 requested other services. To examine the CAARS’ ability to differentiate ADHD symptoms from other Axis I symptoms, it was compared with the Personality Assessment Inventory. Results: The two groups differed significantly on the weighted linear combination of the eight subscales of the CAARS, Wilks’s Lambda = .565, F(7, 105) = 11.56, p < .0001, with higher mean scores found among those requesting evaluation of ADHD. z-tests revealed the eight CAARS subscales were more highly correlated with each other, based on the average intercorrelation, than the nine selected clinical scales of the Personality Assessment Inventory (PAI; Somatic Complaints [SOM], Mania [MAN], Paranoia [PAR], Schizophrenia [SCZ], Anxiety [ANX], Anxiety-Related Disorders [ARD], Depression [DEP], Borderline Features [BOR], and Antisocial Features [ANT]). Some unexpectedly high correlations were found between the CAARS and PAI clinical scales (MAN and SCZ).

Conclusion: The results of the present study were mixed, with some analyses yielding positive results with respect to the CAARS’ sensitivity and others suggesting poor specificity.

Abstract

Free-Press/Fair-Trial contests now happen in a new media age. Judicial remedies such as change-of-venue, sequestration, jury admonitions, and gag orders were fashioned in an era that included broadcast radio and television, an emerging cable television industry, and the traditional print media of newspapers and magazines. That content was, to some degree, geographically bound and temporary. Now those judicial remedies are applied in a new media age that extends the reach of traditional media in time and space while offering interactive capability. The efficacy of these remedies is in question. This paper provides an historical overview of how judicial remedies for pre-trial and trial publicity have developed along with the media industries that provide such publicity. A case study will provide insight into a recent Free Press-Fair Trial contest in which traditional judicial remedies were sought. Finally, the results of an experiment using exposure to media reports in the case study will be discussed. Specifically, reaction to a standard voir dire question regarding pre-trial publicity is measured on a traditional yes/no categorical response and on a semantic differential between not guilty and guilty. The mass media theories of hypodermic needle, two-step flow of communication and uses and gratification theories are compared to contemporaneous judicial estimation of the effects of publicity on the rights of the criminally accused.

Assistant Professor Eric D. Smith from the Department of Psychology co-authored the paper, “How is theory of mind useful? Perhaps to enable social pretend play.” You can read the article in volume six of the open-access journal, Frontiers in Psychology.

Abstract

It is often claimed that theory of mind (ToM) is facilitated by pretend play (PP), or by a particular type of PP, social pretend play (SPP). Here we challenge that view, proposing instead that ToM might be useful for driving SPP, rather than the reverse. We discuss background theory, review pertinent studies, and explain why the “ToM first” view is at least equally likely. -from the article

beckersThis week’s #RacerScholar is Professor Oliver M. Beckers in the Department of Biological Sciences at Murray State University. He contributed to the article, “Differentiation of Ovarian Development and the Evolution of Fecundity in Rapidly Diverging Exotic Beetle Populations,” which appeared in the Nov. 2015 edition of Journal of Experimental Zoology Part A: Ecological Genetics and Physiology.

Abstract

Fecundity is a fundamental determinant of fitness, yet the proximate developmental and physiological mechanisms that enable its often rapid evolution in natural populations are poorly understood. Here, we investigated two populations of the dung beetle Onthophagus taurus that were established in exotic ranges in the early 1970s. These populations are subject to drastically different levels of resource competition in the field, and have diverged dramatically in female fecundity. Specifically, Western Australian O. taurus experience high levels of resource competition, and exhibit greatly elevated reproductive output compared to beetles from the Eastern US, where resource competition is minimal and female fecundity is low. We compared patterns of ovarian maturation, relative investment into and timing of egg production, and potential trade-offs between ovarian investment and the duration of larval development and adult body size between populations representative of both exotic ranges. We found that the rapid divergence in fecundity between exotic populations is associated with striking differences in several aspects of ovarian development: (1) Western Australian females exhibit accelerated ovarian development, (2) produce more eggs, (3) bigger eggs, and (4) start laying eggs earlier compared to their Eastern US counterparts. At the same time, divergence in ovarian maturation patterns occurred alongside changes in (5) larval developmental time, and (6) adult body size, and (7) mass. Western Australian females take longer to complete larval development and, surprisingly, emerge into smaller yet heavier adults than size-matched Eastern US females. We discuss our results in the context of the evolutionary developmental biology of fecundity in exotic populations.
