Reframing Campus Climate Data to Advocate for Institutional Transformation, Praxis, and Activism for LGBQQ+ College Students

In this chapter, Hoffman and Pryor use SERU data to show how LGBQQ+ students perceive campus climate and propose ways scholars and practitioners might reframe these data to advocate for institutional transformation and imagine new ways of being for LGBQQ+ students. The authors use the traditionally heterogendered institution critical conceptual framework to show how a reliance on institutions as the solutions to LGBQQ+ students’ problems may, in fact, constrain ways of being for students and inadvertently uphold existing hierarchies of gender and sexuality. We advocate for scholars and practitioners to use campus climate data to push for institutional transformation, improve praxis, and create avenues for activism that extend beyond the walls of the institution

A multifunction and bidirectional valve-less rectification micropump based on bifurcation geometry

In this paper, we introduce a novel valve-less rectification micropump based on bifurcation geometry. Three micropumps based on three different bifurcation configurations were designed, fabricated and experimentally investigated. These designs demonstrate the potentials of developing bidirectional micropumps and multifunction microfluidic devices (combined functions of micro pumping and mixing). Polydimethylsiloxane (PDMS) was employed to fabricate the micropumps. Circular piezoelectric transducers (PZT) were used as flow actuators. Detailed fabrication procedures are illustrated. The micropumps were tested against two ranges of actuator frequencies. The first test was conducted in a frequency range between 0 and 100 Hz with small increments of 5 Hz, while the second test was conducted in a frequency range between 0 and 300 Hz with increments of 50 Hz. Ethanol was used as the working fluid in all experiments. A new dimensionless parameter was introduced to evaluate the efficiency of valve-less rectification micropumps and determine the optimum operational frequency. The flow rate and maximum back pressure were measured. Results of experiments confirmed and demonstrated the feasibility of valve-less rectification micropumps based on bifurcation geometry at a low frequency range. Additionally, results showed the potentials of multifunctional, bidirectional, and self-priming micropumps
