Composition and change of maritime hammock flora in east-central Florida after 20 years

The vegetation of eight east-central Florida maritime hammocks studied in 1997 were compared to similar data collected over 20 years ago. Study sites are located in the northern half of the Indian River Lagoon system mostly within Canaveral National Seashore and Merritt Island National Wildlife Refuge. The upland hammock vegetation throughout the state generally has an oak-palm association, but here these species dominate. Results show that sabal palm, live oak, laurel oak, and pignut hickory, the four dominant tree species in 1976-77, are still dominant in 1997; however, there has been a loss in tree species richness. Most shrub species found during both studies increased in dominance over the 20 years and there was almost a complete turnover in the composition of herbs. Variability in winter freeze events has caused a unique mixture of plant species to occur here. Many of the maritime hammock’s tropical plants are in the northern limit of their range, giving these hammocks a unique ecotonal character. Tropical invasive exotics have increased in frequency, density, and basal area and pose a threat to this diverse floral complex

Intra-arterial thrombolysis of embolic middle cerebral artery using collateral pathways

Background and purpose: Cervical internal carotid artery (ICA) occlusion associated with middle cerebral artery (MCA) embolic occlusion requires prompt revascularization to prevent devastating stroke. With the advent of endovascular techniques for chemical and mechanical thrombolysis, the clinical outcome of patients with major arterial occlusions will improve. Finding the most expedient pathway to the site of end organ occlusion for thrombolysis is important. Methods: We present two cases of acute stroke secondary to thrombotic occlusion of the cervical ICA associated with MCA embolic occlusion treated with intra-arterial thrombolysis via catheter navigation through the posterior communicating artery to the site of MCA arterial occlusion. No attempt was made to transverse the occluded ICA. Results: Near complete restoration of flow was achieved in one patient and minimal vessel reopening was observed in the other patient. Both patients had good outcomes. Conclusion: Intra-arterial thrombolysis via Circle of Willis collaterals such as the posterior communicating artery for the treatment of acute thrombotic occlusion of the cervical internal carotid artery associated with embolic occlusion of the middle cerebral artery is a therapeutic option. This treatment option avoids the potential complications of navigating through an occluded proximal internal carotid artery and may expedite reopening of the MCA

Design fiction for mixed-reality performances

Designing for mixed-reality performances is challenging both in terms of technology design, and in terms of understanding the interplay between technology, narration, and (the outcomes of) audience interactions. This complexity also stems from the variety of roles in the creative team often entailing technology designers, artists, directors, producers, set-designers and performers. In this multidisciplinary, one-day workshop, we seek to bring together HCI scholars, designers, artists, and curators to explore the potential provided by Design Fiction as a method to generate ideas for Mixed-Reality Performance (MRP) through various archetypes including scripts, programs, and posters. By drawing attention to novel interactive technologies, such as bio-sensors and environmental IoT, we seek to generate design fiction scenarios capturing the aesthetic and interactive potential for mixed-reality performances, as well as the challenges to gain access to audience members’ data – i.e. physiological states, daily routines, conversations, etc

Co-Designing Flavor-Based Memory Cues with Older Adults

This initial study explores the design of flavor-based cues with older adults for their self-defining memories. It proposes using food to leverage the connections between odor and memory to develop new multisensory memory cues. Working with 4 older adults, we identified 6 self-defining autobiographical memories for each participant, 3 related to food, 3 unrelated to food. Flavor-based cues were then created for each memory through a co-design process. Findings indicate the dominance of relationship themes in the identified self-defining memories and that flavor-based cues related mostly to multiple ingredient dishes. We discuss how these findings can support further research and design into flavor-based memory cues through 3D food printing
