The Myth of Neutrality: Linguistic Influence in the Integration of Nonbinary Identities in English and German
Get PDFGrammatical structures that differ among languages can affect the way people of different cultures think, speak, and behave. Because of its close ties with identity, language also has the ability to manipulate the way people view themselves and others. Ethnographic research among English and German speakers shows that these differing grammatical structures affect the integration into society of nonbinary, intersex, and agender individuals through a grammatical predisposition for gender neutral language. As such, the means of increasing social integration of these groups also differs between linguistic and cultural borders
Effects of Climate and Land-Use Changes on Fish Catches Across Lakes at a Global Scale
Get PDFGlobally, our knowledge on lake fisheries is still limited despite their importance to food security and livelihoods. Here we show that fish catches can respond either positively or negatively to climate and land-use changes, by analyzing time-series data (1970–2014) for 31 lakes across five continents. We find that effects of a climate or land-use driver (e.g., air temperature) on lake environment could be relatively consistent in directions, but consequential changes in a lake-environmental factor (e.g., water temperature) could result in either increases or decreases in fish catch in a given lake. A subsequent correlation analysis indicates that reductions in fish catch was less likely to occur in response to potential climate and land-use changes if a lake is located in a region with greater access to clean water. This finding suggests that adequate investments for water-quality protection and water-use efficiency can provide additional benefits to lake fisheries and food security
Testing a Thermodynamic Approach to Collective Animal Behavior in Laboratory Fish Schools
Get PDFCollective behaviors displayed by groups of social animals are observed frequently in nature. Understanding and predicting the behavior of complex biological systems is dependent on developing effective descriptions and models. While collective animal systems are characteristically nonequilibrium, we can employ concepts from equilibrium statistical mechanics to motivate the measurement of material-like properties in laboratory animal aggregates. Here, we present results from a new set of experiments that utilize high speed footage of two-dimensional schooling events, particle tracking, and projected static and dynamic light fields to observe and control the behavior of negatively phototaxic fish schools (Hemigrammus bleheri). First, we use static light fields consisting of dark circular regions to produce visual stimuli that confine the schools to a range of areas. We find that schools have a maximum density which is independent of group size, and that a swim pressurelike quantity, Π increases linearly with number density, suggesting that unperturbed schools exist on an isotherm. Next, we use dynamic light fields where the radius of the dark region shrinks linearly with time to compress the schools. We find that an effective temperature parameter depends on the compression time and our results are thus consistent with the school having a constant heat flux. These findings further evidence the utility of effective thermodynamic descriptions of nonequilibrium systems in collective animal behavior
Using a Student Textbook Survey to Advance an OER Initiative
Get PDFLearn how one library created, administered, and used the results of a student textbook survey in order to advance an OER initiative. We will cover fundamental details, including how we modified an existing survey, chose an administration tool, and promoted the survey. Additionally, we will share our approach to analyzing data and sharing results with various campus stakeholders. This session will focus on the practical aspects of the project in hopes that other libraries will feel empowered to conduct local surveys that support programmatic goals
