TL;DR: It was concluded that at 70% of vVO (2)max pace, barefoot running is more economical than running shod, both overground and on a treadmill.
Abstract: The purpose of this study was to investigate the oxygen cost of running barefoot vs. running shod on the treadmill as well as overground. 10 healthy recreational runners, 5 male and 5 female, whose mean age was 23.8±3.39 volunteered to participate in the study. Subjects participated in 4 experimental conditions: 1) barefoot on treadmill, 2) shod on treadmill, 3) barefoot overground, and 4) shod overground. For each condition, subjects ran for 6 min at 70% vVO 2 max pace while VO 2 , heart rate (HR), and rating of perceived exertion (RPE) were assessed. A 2 × 2 (shoe condition x surface) repeated measures ANOVA revealed that running with shoes showed significantly higher VO 2 values on both the treadmill and the overground track (p<0.05). HR and RPE were significantly higher in the shod condition as well (p<0.02 and p<0.01, respectively). For the overground and treadmill conditions, recorded VO 2 while running shod was 5.7% and 2.0% higher than running barefoot. It was concluded that at 70% of vVO 2 max pace, barefoot running is more economical than running shod, both overground and on a treadmill.

TL;DR: This paper examined employees' attitudes toward fun, their perceptions of what is (and is not) fun, and the role of trust in the supervisor and coworkers across three sectors: public, nonprofit, and private.
Abstract: This study examined the issue of "fun at work" across three sectors: public, nonprofit, and private. Specifically, we examined employees' attitudes toward fun, their perceptions of what is (and is not) fun, and the role of trust in the supervisor and coworkers. While there were no significant differences across the three sectors in their attitudes toward fun, there were significant differences across sectors in their ratings of the company-wide outings category and ten (of forty) individual fun activities. Public sector employees tended to rate the activities as less fun than at least one of the other two groups. Employees in all three sectors agreed that food-related activities were fun. In addition, attitudes toward fun were found to be positively related to trust in one's supervisor and trust in one's coworkers. The implications of these results and directions for future research are discussed.

TL;DR: In this paper, the relationship between engagement and intent to remain with the organization, based upon variations in the racial composition of the supervisor-employee dyad, was examined and found that at low levels of engagement, members of different-race dyads report a lower tendency to stay with their organization for at least one year than members of same race dyads.
Abstract: In this paper we review extant research findings on employee engagement. We then outline and test potential differences in the relationship between engagement and intent to remain with the organization, based upon variations in the racial composition of the supervisor-employee dyad. Our analyses revealed an interaction whereby at low levels of engagement, members of different-race dyads report a lower tendency to remain with their organization for at least one year than members of same-race dyads; at high levels of engagement, intent to remain was greater for members of different-race dyads. We discuss implications of our findings for organizational practice and research.

TL;DR: In this article, the authors employ a state-space model to model the dynamics of the log price-dividend ratio along with long-term and short-term interest rates, real dividend growth, and inflation.
Abstract: Previous analyses have concluded that expectations of future excess stock returns rather than future real dividend growth or real interest rates are responsible for most of the volatility in stock prices. In this paper, we employ a state-space model to model the dynamics of the log price-dividend ratio along with long-term and short-term interest rates, real dividend growth, and inflation. The advantage of the state-space approach is that we can parsimoniously model the low-frequency movements present in the data. We find that, if one allows permanent changes, even though very small, in real dividend growth, real interest rates, and inflation-but not excess stock returns-then expectations of real dividend growth and real interest rates become significant contributors to fluctuations in stock prices. However, we also show that stock price decompositions are very sensitive to assumptions about which unobserved market fundamentals have a permanent component. When we allow excess stock returns to have a perma...

TL;DR: A study that adapts a previously developed instrument to measure cognitive load to a new discipline, introductory computer science, and the results of measuring the cognitive load factors of specific lectures are reported.
Abstract: A student's capacity to learn a concept is directly related to how much cognitive load is used to comprehend the material. The central problem identified by Cognitive Load Theory is that learning is impaired when the total amount of processing requirements exceeds the limited capacity of working memory. Instruction can impose three different types of cognitive load on a student's working memory: intrinsic load, extraneous load, and germane load. Since working memory is a fixed size, instructional material should be designed to minimize the extraneous and intrinsic loads in order to increase the amount of memory available for the germane load. This will improve learning. To effectively design instruction to minimize cognitive load we must be able to measure the specific load components for any pedagogical intervention. This paper reports on a study that adapts a previously developed instrument to measure cognitive load. We report on the adaptation of the instrument to a new discipline, introductory computer science, and the results of measuring the cognitive load factors of specific lectures. We discuss the implications for the ability to measure specific cognitive load components and use of the tool in future studies.
