TL;DR: In this paper, a metadata analysis of 563 direct gas tracer release experiments was conducted to examine scaling laws for the gas transfer velocity and the product of stream slope and velocity, which is in alignment with theory on stream energy dissipation.
Abstract: Scaling is an integral component of ecology and earth science. To date, the ability to determine the importance of air – water gas exchange across large spatial scales is hampered partly by our ability to scale the gas transfer velocity and stream hydraulics. Here we report on a metadata analysis of 563 direct gas tracer release experiments that examines scaling laws for the gas transfer velocity. We found that the gas transfer velocity scales with the product of stream slope and velocity, which is in alignment with theory on stream energy dissipation. In addition to providing equations that predict the gas transfer velocity based on stream hydraulics, we used our hydraulic data set to report a new set of hydraulic exponents and coefficients that allow the prediction of stream width, depth, and velocity based on discharge. Finally, we report a new table of gas Schmidt number dependencies to allow researchers to estimate a gas transfer velocity using our equation for many gasses of interest.

TL;DR: This article examined the belief that physical abuse of wives is strongly determined by drunkenness and socioeconomic status using interview data from a nationally representative sample of 5,159 families and found that excessive drinking is associated with higher wife abuse rates, but alcohol use is not an immediate antecedent of violence in the majority of families.
Abstract: We examine the belief that physical abuse of wives is strongly determined by drunkenness and socioeconomic status using interview data from a nationally representative sample of 5,159 families. Our findings show that excessive drinking is associated with higher wife abuse rates, but alcohol use is not an immediate antecedent ofviolence in the majority of families. The combination of blue-collar status, drinking, and approval of violence is significantly associated with the highest rate of wife abuse. Of the three factors, cultural approval of violence by men against women has the strongest association with wife abuse. Although our results provide support for the drunken bum theory of wife beating, they also demythologize the stereotype because they show that alcohol is far from being a necessary or sufficient cause of wife abuse.

TL;DR: In this paper, a variety of methods developed in the literature (in particular, the theory of weak Hopf algebras), are used to prove a number of general results about fusion categories in characteristic zero.
Abstract: Using a variety of methods developed in the literature (in particular, the theory of weak Hopf algebras), we prove a number of general results about fusion categories in characteristic zero. We show that the global dimension of a fusion category is always positive, and that the S-matrix of any modular category (not necessarily hermitian) is unitary. We also show that the category of module functors between two module categories over a fusion category is semisimple, and that fusion categories and tensor functors between them are undeformable (generalized Ocneanu rigidity). In particular the number of such categories (functors) realizing a given fusion datum is finite. Finally, we develop the theory of Frobenius-Perron dimensions in an arbitrary fusion category and classify categories of prime dimension.

TL;DR: In this article, the authors quantified the effects of both deforestation and selective logging, separately and combined, on forest fragmentation and edge effects over large regions, and contextualized the spatio-temporal dynamics of this forest fragmentation through a literature review of potential ecological repercussions of edge creation.

TL;DR: A review of the status and major challenges in representing the impacts of disturbances in modeling the carbon dynamics across North America revealed some major advances and challenges as mentioned in this paper, and significant advances have been made in representation, scaling, and characterization of disturbances that should be included in regional modeling efforts.
Abstract: [1] Forest disturbances greatly alter the carbon cycle at various spatial and temporal scales. It is critical to understand disturbance regimes and their impacts to better quantify regional and global carbon dynamics. This review of the status and major challenges in representing the impacts of disturbances in modeling the carbon dynamics across North America revealed some major advances and challenges. First, significant advances have been made in representation, scaling, and characterization of disturbances that should be included in regional modeling efforts. Second, there is a need to develop effective and comprehensive process‐based procedures and algorithms to quantify the immediate and long‐term impacts of disturbances on ecosystem succession, soils, microclimate, and cycles of carbon, water, and nutrients. Third, our capability to simulate the occurrences and severity of disturbances is very limited. Fourth, scaling issues have rarely been addressed in continental scale model applications. It is not fully understood which finer scale processes and properties need to be scaled to coarser spatial and temporal scales. Fifth, there are inadequate databases on disturbances at the continental scale to support the quantification of their effects on the carbon balance in North America. Finally, procedures are needed to quantify the uncertainty of model inputs, model parameters, and model structures, and thus to estimate their impacts on overall model uncertainty. Working together, the scientific community interested in disturbance and its impacts can identify the most uncertain issues surrounding the role of disturbance in the North American carbon budget and develop working hypotheses to reduce the uncertainty.
