Metaanalysis Of The Relationship Between Violent Video Game Play And Physical Aggression Over Time, Anna T. Prescott, James Sargent, Jay G. Hull
Metaanalysis Of The Relationship Between Violent Video Game Play And Physical Aggression Over Time, Anna T. Prescott, James Sargent, Jay G. Hull
Dartmouth Scholarship
To clarify and quantify the influence of video game violence (VGV) on aggressive behavior, we conducted a metaanalysis of all prospective studies to date that assessed the relation between exposure to VGV and subsequent overt physical aggression. The search strategy identified 24 studies with over 17,000 participants and time lags ranging from 3 months to 4 years. The samples comprised various nationalities and ethnicities with mean ages from 9 to 19 years. For each study we obtained the standardized regression coefficient for the prospective effect of VGV on subsequent aggression, controlling for baseline aggression. VGV was related to aggression using …
Orecchio: Extending Body-Language Through Actuated Static And Dynamic Auricular Postures, Da-Yuan Huang, Teddy Seyed, Jun Gong, Zhihao Yao, Yuchen Jiao, Xiang Anthony Chen, Xing-Dong Yang
Orecchio: Extending Body-Language Through Actuated Static And Dynamic Auricular Postures, Da-Yuan Huang, Teddy Seyed, Jun Gong, Zhihao Yao, Yuchen Jiao, Xiang Anthony Chen, Xing-Dong Yang

In this paper, we propose using the auricle – the visible part of the ear – as a means of expressive output to extend body language to convey emotional states. With an initial exploratory study, we provide an initial set of dynamic and static auricular postures. Using these results, we examined the relationship between emotions and auricular postures, noting that dynamic postures involving stretching the top helix in fast (e.g., 2Hz) and slow speeds (1Hz) conveyed intense and mild pleasantness while static postures involving bending the side or top helix towards the center of the ear were associated with intense …
Small-Scale Forestry And Carbon Offset Markets: An Empirical Study Of Vermont Current Use Forest Landowner Willingness To Accept Carbon Credit Programs, Alisa E. White, David A. Lutz, Richard B. Howarth, José R. Soto
Small-Scale Forestry And Carbon Offset Markets: An Empirical Study Of Vermont Current Use Forest Landowner Willingness To Accept Carbon Credit Programs, Alisa E. White, David A. Lutz, Richard B. Howarth, José R. Soto
Dartmouth Scholarship
This study investigates the preferences of small forest landowners regarding forest carbon credit programs while documenting characteristics of potentially successful frameworks. We designed hypothetical carbon credit programs with aggregated carbon offset projects and requirements of existing voluntary and compliance protocols in mind. We administered a mail survey to 992 forest landowners in Vermont’s Current Use Program utilizing best-worst choice, a novel preference elicitation technique, to elicit their preferences about these programs. We found that small forest landowners see revenue as the most important factor in a carbon credit program and the duration of the program as the least important factor. …
Spatial Heterogeneity In The Abundance And Fecundity Of Arctic Mosquitoes, Lauren E. Culler, Matthew P. Ayres, Ross A. Virginia
Spatial Heterogeneity In The Abundance And Fecundity Of Arctic Mosquitoes, Lauren E. Culler, Matthew P. Ayres, Ross A. Virginia
Dartmouth Scholarship
The abundance of mosquitoes is strongly influenced by biotic and abiotic factors that act on the immature (aquatic) and adult (terrestrial) life stages. Rapid changes in land use and climate, which impact aquatic and terrestrial mosquito habitat, necessitate studying the ecological mechanisms, and their interplay with the changing environment, that affect mosquito abundance. These data are crucial for anticipating how environmental change will impact their roles as pests, disease vectors, and in food webs. We studied a population of Arctic mosquitoes (Aedes nigripes, Diptera: Culicidae) in western Greenland, a region experiencing rapid environmental change, to quantify spatial variation …
A Nearly Complete Foot From Dikika, Ethiopia And Its Implications For The Ontogeny And Function Of Australopithecus Afarensis, Jeremy Desilva, Corey M. Gill, Thomas C. Prang, Miriam A. Bredella, Zeresenay Alemseged
A Nearly Complete Foot From Dikika, Ethiopia And Its Implications For The Ontogeny And Function Of Australopithecus Afarensis, Jeremy Desilva, Corey M. Gill, Thomas C. Prang, Miriam A. Bredella, Zeresenay Alemseged
Dartmouth Scholarship
The functional and evolutionary implications of primitive retentions in early hominin feet have been under debate since the discovery of Australopithecus afarensis. Ontogeny can provide insight into adult phenotypes, but juvenile early hominin foot fossils are exceptionally rare. We analyze a nearly complete, 3.32-million-year-old juvenile foot of A. afarensis (DIK-1-1f). We show that juvenile A. afarensis individuals already had many of the bipedal features found in adult specimens. However, they also had medial cuneiform traits associated with increased hallucal mobility and a more gracile calcaneal tuber, which is unexpected on the basis of known adult morphologies. Selection for traits …

Propensity To Patent And Firm Size For Small R&D-Intensive Firms, Albert N. Link, John T. Scott
Propensity To Patent And Firm Size For Small R&D-Intensive Firms, Albert N. Link, John T. Scott
Dartmouth Scholarship
The Schumpeterian hypothesis about the effect of firm size on research and development (R&D) output is studied for a sample of R&D projects for R&D-intensive firms that are small but have substantial variance in their sizes. Across the distribution of firm sizes, the elasticity of patenting with respect to R&D ranged from 0.41 to 0.55, with the elasticities being largest for intermediate levels of firm size and also varying directly with the extent to which the projects are Schumpeterian in the cost or value senses. The paper’s findings at the R&D project level are compared with the literature’s findings at …
