Sensitive plant (Mimosa pudica) hiding time depends on individual and state.

The decisions animals make to adjust their antipredator behavior to rapidly changing conditions have been well studied. Inducible defenses in plants are an antipredator behavior that acts on a longer time scale, but sensitive plants, Mimosa pudica, have a much more rapid antipredator response; they temporarily close their leaves when touched. The time they remain closed is defined as hiding time. We studied hiding time in sensitive plants and found that individual plants differed significantly in their hiding times. We then showed that the effect of individual explained substantial variation in hiding time on a short time scale. Finally, on a longer time scale, individuality persisted but the amount of variation attributed to individual decreased. We hypothesized that variation in plant condition might explain this change. We therefore manipulated sunlight availability and quantified hiding time. When deprived of light for 6 h, sensitive plants significantly shortened their hiding times. But when only half a plant was deprived of light, hiding times on the deprived half and light exposed half were not significantly different. This suggests that overall condition best explains variation in sensitive plant antipredator behavior. Just like in animals, sensitive plant antipredator behavior is condition dependent, and, just like in animals, a substantial amount of the remaining variation is explained by individual differences between plants. Thus, models designed to predict plasticity in animal behavior may be successfully applied to understand behavior in other organisms, including plants

Historical analysis of depreciation accounting -- The United States Steel experience

This paper examines the magnitude of the reporting bias inherent in the historical cost accounting of a firm\u27s physical capital. Reported depreciation data pertaining to U.S. Steel Corporation (currently USX) between 1939 and 1987 are compared with standardized historical cost figures and replacement cost estimates. The findings suggest that replacement cost depreciation would have provided more information about U.S. Steel\u27s ability to maintain its productive capacity than historical cost depreciation did. Thus, this analysis provides an illustration of one of the primary arguments for replacement cost accounting

Skipped breeding in common guillemots in a changing climate: restraint or constraint?

Climate change may have demographic consequences for marine top predators if it leads to altered rates of skipped breeding. Here we examine variation in skipping propensity at both the population and individual levels in common guillemots Uria aalge in relation to climate and oceanographic variables and explore the extent to which skipping may be adaptive or an unavoidable consequence of ecological or social constraints. We assumed a detection probability for birds present in the colony of 1.00 and skipping events were defined to include both resightings of non-breeders and failures to resight individuals known to be alive (not present at the colony but resighted in future years). Skipping frequency was higher in years where sea surface temperatures (SST) were higher in winter (both in the current and previous year), when guillemots from our study colony disperse widely across the southern North Sea. Individuals differed consistently in their average skipping propensity and their responses to SST. Males and females were equally likely to skip on average and the frequency of skipping increased in the oldest age classes. Birds that skipped in year t had lower breeding success in year t+1 if they laid an egg, compared to birds that did not skip in year t. Lifetime reproductive output was negatively related to individual skipping frequency. These results imply that skipping is driven more by individual-specific constraints, although we cannot rule out the possibility that birds benefit from skipping when environmental (or internal) signals indicate that breeding in poor years could be detrimental to their residual reproductive value. While future climate change might lead to guillemots skipping more often due to carry-over effects from wintering to breeding periods, the net demographic impacts may be subtle as the absolute frequency of skipping may remain low and individuals will not be equally affected

Instructional Alignment of Workplace Readiness Skills in Marketing Education

This study examined high school marketing education teachers’ knowledge of workplace readiness skills and whether that knowledge had an impact on student workplace readiness skill achievement. Further, this study examined the usage of Virginia’s 13 Workplace Readiness Skills curriculum and identified the teaching methods and instructional strategies used to disseminate the skills to students. Three sets of data were used for this study: teacher workplace readiness skills data, teacher survey data, and student workplace readiness skills post-test data. Pearson’s correlation was used to determine whether teacher knowledge of workplace readiness skills had an impact on student attainment of the same. The results showed that while overall teacher scores did not show a statistical significance on overall student scores, there were four individual skill areas in which there was a relationship between teacher and student scores

A Case Study of Tu and Vous Use in the French Dubbing and Subtitling in an American Film

Translation and subtitling has always been a complicated dimension of the motion picture industry for years. The problem of dealing with linguistic elements in films and conveying them to audiences of different languages across the globe encompasses many difficulties regarding forms and structures of other languages. One of the more highly researched topics in French linguistic studies has been the use of address pronouns and a range of aspects related to their use and interpretation. Many studies have been conducted over the last sixty years in order to determine and understand these variables. An analysis of several of these studies reveals the many complexities involved in second-person pronoun choice in the French language and the development of the idea of pronoun choice as an act of social identity. The focus of this study is to provide an analysis of the use of formal and informal address pronoun use in the French subtitling and dubbing of an American film, Maid in Manhattan, in order to add, on a broader level, a way to differentially examine perceived norms in a variety of contexts within this medium
