Temporal changes in the spatial variability of shear strength and stability.

Avalanche forecasting involves the prediction of spatial and temporal variability of the snowpack. To predict avalanches with more accuracy it is important to determine whether the snowpack is becoming more spatially variable or more spatially uniform. Greater variability increases uncertainty in extrapolation and prediction. Our results offer a look at the evolution of the spatial variability of shear strength and stability of a buried surface hoar layer in southwestern Montana, USA, from shortly after burial until it was no longer the weakest layer in the snowpack. We selected the study site for its 27- degree planar slope, uniform ground cover, and wind-sheltered location. This simplified the comparison of the plots by minimizing initial spatial differences so we could focus on temporal change. Within the site, we sampled four 14 m x 14 m arrays of more than 70 shear frame tests in a layout optimized for spatial analysis. Over a three-week period, the sampling of the four adjacent arrays showed temporal change. The variability of the shear strength of this layer initially decreased then became increasingly variable through time. This suggests that extrapolating test results to other locations becomes increasingly unreliable as layers age, a result that matches practical experience. The data also provide indications that shear strength has a correlation length, the distance at which test results are related, of just a few meters. This short correlation length demonstrates quantitatively why stability tests that are relatively close together can be quite different

Putting passion to work: Passionate labour in the fashion blogosphere

PurposeThis study aims to explore passionate labour in the fashion blogosphere and addresses two research questions: How does passion animate passionate labour? How does the emotion of passions and the discipline of labour fuse within passionate labour?Design/methodology/approachThis study presents a three-year netnographic fieldwork of replikate fashion blogger-preneurs. Data are based on in-depth interviews, blogs, social media posts and informed by the relationships developed across these platforms.FindingsThroughout the findings, this study unpacks the “little passions” that animate the passionate labour of blogger-preneurs. Passions include: passion for performing the royal lifestyle, the mobilisation of passion within strategic sociality and transformation and self-renewal through blogging. Lastly, the cycle of passion illustrates how passions can be recycled into new passionate projects.Research limitations/implicationsThis study offers insight on how passionate labour requires the negotiation and mobilisation of emotion alongside a calculated understanding of market logics.Practical implicationsThis study raises implications for aspiring blogger-preneurs, luxury brand managers and organisations beyond the blogging context.Originality/valueThe contribution of this study lies in the cultural understanding of passion as a form of labour where passion has become a way of life. The theorisation of passionate labour contributes to existing research in three ways. First, this study identifies social mimesis as a driver of passionate labour and its links to class distinction. Second, it offers insight on how passionate labour requires the negotiation and mobilisation of emotion alongside a calculated understanding of market logics. Third, it advances critical debate around exploitation and inequality within digital labour by demonstrating how passion is unequally distributed
