Chatterjee, Anindya (School of Business) and Richard Parker (2012) “Consumer Preference for Bulk Purchasing: Evidence from Exploratory Surveys,” Global Business Review, 1(3), 173-178.
Abstract: Many consumers are willing to purchase goods in large quantities in exchange for lower prices. Marketers have responded by offering incentives for bulk purchases, and by developing new retail formats such as warehouse clubs. However, little research has been done to identify the characteristics of consumers interested in bulk purchasing. The present research based on surveys of American and Singaporean consumers, sheds some light on demographic and lifestyle characteristics of consumers that marketers may benefit from targeting with incentives for bulk purchases.
Emekter, Riza, Benjamas Jirasakuldech (School of Business), and Peter Went (2012) “Rational speculative bubbles and commodities markets: application of duration dependence test,” Applied Financial Economics, 22(7), 581-596.
Abstract: The presence of rational speculative bubbles in 28 commodities is investigated using the duration dependence test on the stochastic interest-adjusted basis. Eleven of 28 commodities experienced some episodes of rational speculative bubble. These commodities are West Texas Intermediate (WTI) crude oil, coffee, corn, soya bean No. 2, soya bean meal and oil, wheat No. 2 soft red and hard winter wheat, lean hogs, gold and platinum. Additionally, natural gas, propane, live cattle, and pork bellies exhibit mean-reversion in the interest-adjusted basis.
Getsay, Heather and Catherine Rudowsky (Bailey Library) (2013) “Identifying the serials librarian: Serials-related position titles in the United States and around the world,” The Serials Librarian, 65(3-4), 374-388. doi:10.1080/0361526X.2013.836463.
Abstract: Serials are a familiar academic job responsibility, but serials librarians are becoming difficult to identify. While serials continue to exist, the transition from print to electronic resources contributes to a trend in which the job titles of librarians who manage serials no longer include the word “serials.” A content analysis was conducted to examine the prevalence of the word “serials,” as well as common synonyms including “continuing resources” and “periodicals,” in U.S. and non-U.S. academic library job titles. In a sample of 98 U.S. national and regional universities and colleges, 18 librarian and 98 staff job titles were found that included the word “serials” or a synonym for serials. By comparison, a sample of 71 universities from 8 non-U.S. countries revealed 17 librarian and 85 staff job titles that included the word “serials” or a synonym for serials.
Holmstrup, Michael (Department of Exercise and Rehabilitative Sciences), AJ Bidwell, and TJ Fairchild (2014) “Body image does not predict caloric estimation accuracy,” Topics in Clinical Nutrition, 29(1), 15-21.
Abstract: The present study characterized caloric estimation accuracy of prepared, healthy meals, with the specific hypothesis that individuals with greater body-dissatisfaction will overestimate calorie content. Ninety-eight individuals estimated the number of calories in four separate healthy meals. Differences in the bias of caloric estimation were determined in relation to sex, BMI, body fat percentage, and body image dissatisfaction. Subjects, regardless of sex, weight status, and body image tended to overestimate the number of calories in prepared, healthy meals. Quantifying portion size makes the task of caloric estimation in prepared meals more difficult, and should be addressed to enhance accuracy.
Holmstrup, Michael (Department of Exercise and Rehabilitative Sciences), TJ Fairchild, S Keslacy, RS Weinstock, JA Kanaley (2013) “Multiple short bouts of exercise over 12-h period reduce glucose excursions more than an energy-matched single bout of exercise,” Metabolism, Accepted 11 December 2013, doi: 10.1016/j.metabol.2013.12.006.
Objective: Long, uninterrupted bouts of sedentary behavior are thought to negatively influence postprandial glucose and insulin concentrations. We examined the effects of a 1-h bout of morning exercise versus intermittent walking bouts of short duration on glucose excursions and insulin secretion over 12-h. Materials/Methods: Eleven young, obese individuals (18–35 years, BMI > 30 kg/m2) with impaired glucose tolerance were studied on three 12-h study days: 1) sedentary behavior (SED); 2) sedentary behavior with 1-h morning exercise (EX) at 60%–65% VO2peak; and 3) sedentary behavior with 12-hourly, 5-min intervals of exercise (INT) at 60%–65% VO2peak. Meals (1046 kJ/meal) were provided every 2-h. Blood samples were collected every 10 min and measured for glucose, insulin, and c-peptide concentrations. Results: Glucose iAUC (12-h) was attenuated in the INT and SED conditions compared to the EX condition (P < 0.05). Glucose concentrations were higher in the EX compared to the SED condition for ~ 150 min (20% of the study day), and comparison of the EX-INT study days revealed that glucose concentrations were greater for ~ 240 min (~ 1/3 of the 12-h day). In the SED condition, the 12-h insulin iAUC was ~ 15% higher (P < 0.05) compared to the INT and EX conditions. Insulin production rate was found to increase ~ 20% with INT exercise vs. the SED and EX condition (P < 0.05). Conclusions: Short, frequent periods of exercise attenuated glucose excursions and insulin concentrations in obese individuals to a greater degree than an equal amount of exercise performed continuously in the morning.

Schneider, and Reid Hayward (2013) “Switching to a low-fat diet attenuates the intensified doxorubicin cardiotoxicity associated with high-fat feeding,” Cancer Chemotherapy Pharmacology, 71(6), 1551-1560.
Abstract: A high-fat diet has been shown to exacerbate the cardiotoxicity associated with the chemotherapy drug doxorubicin (DOX); however, it is unknown whether switching from a high-fat diet to a low-fat diet can attenuate the intensified DOX cardiotoxicity. The purpose of this study was to investigate the effects of a low-fat diet on DOX-induced cardiotoxicity in rats previously fed a high-fat diet. Male rats were randomly assigned to consume a Western diet or a low-fat diet for 6 weeks. Western diet-fed rats were then further randomized to switch to the low-fat diet (WD-LF) or continue with the Western diet (WD). One week later, WD-LF and WD received 1 mg/kg DOX per day for 10 consecutive days and continued with their diets (WD-LF + DOX, WD + DOX). LF was further randomized to receive 1 mg/kg DOX per day for 10 consecutive days (LF + DOX) or saline injections as a control (LF + SAL). Four weeks following the first injection, cardiac function was analyzed, and left ventricles were analyzed for cardiotoxicity indices. When compared to LF + SAL and LF + DOX, WD + DOX exhibited an enhanced cardiotoxicity as evidenced by reduced septal wall thickness, fractional shortening, and sarco-endoplasmic reticulum Ca(2+) ATPase expression as well as increased left ventricular cavity dimensions, lipid peroxidation, and β-myosin heavy-chain expression. This exacerbated cardiotoxicity was not observed in WD-LF + DOX. Switching to a low-fat diet 1 week prior to, during, and following DOX treatment attenuated the exacerbated cardiotoxicity observed in the previously Western diet-fed rats.

Abstract: Doxorubicin (DOX) is an effective antineoplastic agent with well-characterized cardiotoxic effects. Although exercise has been shown to protect against DOX cardiotoxicity, a clear and concise mechanism to explain its cardioprotective effects is lacking. The purpose of this study was to determine if exercise training reduces cardiac DOX accumulation, thereby providing a possible mechanism to explain the cardioprotective effects of exercise against DOX toxicity. Sprague-Dawley rats were randomly assigned to 1 of 3 primary experimental groups: sedentary (n = 77), wheel running (n = 65), or treadmill (n = 65). Animals in wheel running and treadmill groups completed 10 weeks of exercise before DOX treatment. DOX was administered 24 hours after the last training session as a bolus intraperitoneal injection at 10 mg/kg. Subgroups of rats from each primary group were killed at 1, 3, 5, 7, and 9 days after DOX exposure to assess cardiac function and DOX accumulation. Ten weeks of exercise preconditioning reduced myocardial DOX accumulation, and this reduction in accumulation was associated with preserved cardiac function. These data suggest that the cardioprotective effects of exercise against DOX-induced injury may be due, in part, to a reduction in myocardial DOX accumulation.
Katsafanas, Jodi (Department of Special Education) (2014) “Pathways to Developing interculturally aware teachers,” The Field Journal, Spring 2014.
Abstract: The need to graduate well-prepared teachers to staff our culturally diverse and globally connected classrooms is a significant concern to all U.S. teacher education programs. Three pathways are presented for supporting intercultural field experiences that involve modeling, introducing knowledge and skills, and using on-going reflection activities. These activities, coupled with field experiences either internationally or in U.S. cultural minority communities, can help develop interculturally aware teachers.
Wang, Jianyu, Wenhao Liu, and Wei Bian (Department of Physical and Health and Education) (2013) “Relationship between perceived and actual motor competence among college students,” Perceptual & Motor Skills, 116(1), 272-279.
Abstract: The relationship between perceived and actual motor competence was examined among college students. Participants were 114 college students (55 men, 59 women; M age = 22.3 yr., SD = 3.9). All participants completed a short survey on perception of motor competence in basketball and took a Control Basketball Dribble Test to assess their actual motor skill. Perceived motor competence in basketball was significantly related to basketball dribbling performance. Given the positive relationship between actual motor competence and perceived competence, enhancing an individual's actual motor competence may contribute to their perceived competence, which may improve an individual's physical activity participation.
