Sovansky, E. E., Wieth, M. B., Francis, A. P., & McIlhagga, S. D. (2014). Not all musicians are creative: Creativity requires more than simply playing music. Psychology of Music.

Abstract: Musical training has been found to be associated with increased creativity. However, it is not clear whether increased creativity, particularly divergent thinking, is associated with music expertise due to knowledge and skill, or if increased creativity arises from participation in the creation of music through practices such as improvisation and composition. This study investigated how level of music expertise and engagement in the creation of music relate to divergent thinking in musically trained adults (musicians). Sixty participants of varying music expertise were tested for divergent thinking using a modified version of Guilford’s (1967) alternative uses task, in which participants listed creative uses for two music items and two non-music items. Results indicate that musicians who create music listed more creative uses for music items than non-musicians and musicians who do not create music. For non-music items, participants did not display differences in divergent thinking.

Abstract: This paper seeks to further investigate the quandary of closed-end fund discounts known as the “four-piece puzzle.” While other researchers have taken a behavior approach (investor sentiment, etc.), this study will explore empirical data on several variables, including some Fama-French factors. Using a fixed effects model, the effects of turnover, three-year-beta, price/book, median market capitalization, expenses and income were measured in this study.

Hill, E., Terrell, H., Arellano, A., Schuetz, B., & Nagoshi, C. (2014). A Good Story: Using Future Life Narratives to Predict Present Well-Being. Journal of Happiness Studies, 1-20.

Abstract: The present research examined the predictive and nomological validity of a narrative method for assessing goals. College students (N = 337, 158 women, M age = 19.08) from a large, public university wrote short narratives about their best possible selves in the future, imagining that they had realized all of their life dreams. Narratives were coded in terms of the number of statements reflecting each of fourteen types of goals. Intercoder reliability was strong. With regard to predictive validity, intrinsic goals, particularly spiritual and intimacy goals were positively related to well-being. Extrinsic goals, power goals in particular, tended to be negatively related to well-being. With regard to nomological validity, the spiritual goals-well-being relationship was mediated by frequency of religious service attendance and self-report measures of religiosity. Interestingly, intrinsic goals were negatively related to life satisfaction. Results are discussed in the context of self-determination theory and the internalization of extrinsic motivations.

Abstract: Indigenous bacterial assemblages with putative hydrocarbon-degrading capabilities were isolated, characterized and screened for the presence of the catechol-2,3-dioxygenase (C23O) gene after exposure to toluene in two different (i.e., pristine and conditioned) soil communities. The indigenous bacterial populations were exposed to the hydrocarbon substrate by the addition of toluene concentrations, ranging from 0.5 % to 10 % V/W in 10 g of each soil and incubated at 30 °C for upwards of 12 days. In total, 25 isolates (11 in pristine soil and 14 in conditioned soil) were phenotypically characterized according to standard microbiological methods and also screened for the 238-bp C23O gene fragment. Additionally, 16S rRNA analysis of the isolates identified some of them as belonging to the genera Bacillus, Exiguobacterium, Enterobacter, Pseudomonas and Stenotrophomonas. Furthermore, the two clone libraries that were constructed from these toluene-contaminated soils also revealed somewhat disparate phylotypes (i.e., 70 % Actinobacteria and Firmicutes to 30 % Proteobacteria in conditioned soil, whereas in pristine soil: 66 % Actinobacteria and Firmicutes; 21 % Proteobacteria and 13 % Bacteroidetes). The differences observed in bacterial phylotypes between these two soil communities may probably be associated with previous exposure to hydrocarbon sources by indigenous populations in the conditioned soil as compared to the pristine soil.

Wilson, W. J., Ferrara, N. C., Blaker, A. L., & Giddings, C. E. (2014). Escape and avoidance learning in the earthworm Eisenia hortensis. PeerJ, 2, e250.

Abstract: Interest in instrumental learning in earthworms dates back to 1912 when Yerkes concluded that they can learn a spatial discrimination in a T-maze. Rosenkoetter and Boice determined in the 1970s that the “learning” that Yerkes observed was probably chemotaxis and not learning at all. We examined a different form of instrumental learning: the ability to learn both to escape and to avoid an aversive stimulus. Freely moving “master” worms could turn off an aversive white light by increasing their movement; the behavior of yoked controls had no effect on the light. We demonstrate that in as few as 12 trials the behavior of the master worms comes under the control of this contingency.

Abstract: Sugars of extraterrestrial origin have been observed in the interstellar medium (ISM), in at least one comet spectrum, and in several carbonaceous chondritic meteorites that have been recovered from the surface of the Earth. The origins of these sugars within the meteorites have been debated. To explore the possibility that sugars could be generated during shock events, this paper reports on the results of the first laboratory impact experiments wherein glycolaldehyde, found in the ISM, as well as glycolaldehyde mixed with montmorillonite clay, have been subjected to reverberated shocks from ~5 to >25 GPa. New biologically relevant molecules, including threose, erythrose and ethylene glycol, were identified in the resulting samples. These results show that sugar molecules can not only survive but also become more complex during impact delivery to planetary bodies.

Abstract: Nanoscience is one of the fast growing fields in science and engineering. Curricular materials ranging from laboratory experiments to entire courses have been developed for undergraduate science majors. However, little material has been developed for the nonmajor students. Here we present a semester-long laboratory sequence developed for a nonmajors course, where students investigate the potential environmental impacts of nanoscience. Students synthesize and characterize silver nanoparticles using green synthetic methods. They then use the suspension of silver nanoparticles to “water” Wisconsin Fast Plants, Brassica rapa, over a three to four week period to simulate environmental exposure. Possible impacts are examined throughout the growth period, and silver uptake by the plants is quantified at the end of the growth period. This lab requires design input from the student, making it an open-ended experiment. Although designed for nonmajors, this lab could easily be adapted for an environmental chemistry or chemical nanoscience course.
