    Non-Linear Interactions between Consumers and Flow Determine the Probability of Plant Community Dominance on Maine Rocky Shores

    Although consumers can strongly influence community recovery from disturbance, few studies have explored the effects of consumer identity and density and how they may vary across abiotic gradients. On rocky shores in Maine, recent experiments suggest that recovery of plant- or animal- dominated community states is governed by rates of water movement and consumer pressure. To further elucidate the mechanisms of consumer control, we examined the species-specific and density-dependent effects of rocky shore consumers (crabs and snails) on community recovery under both high (mussel dominated) and low flow (plant dominated) conditions. By partitioning the direct impacts of predators (crabs) and grazers (snails) on community recovery across a flow gradient, we found that grazers, but not predators, are likely the primary agent of consumer control and that their impact is highly non-linear. Manipulating snail densities revealed that herbivorous and bull-dozing snails (Littorina littorea) alone can control recovery of high and low flow communities. After ∼1.5 years of recovery, snail density explained a significant amount of the variation in macroalgal coverage at low flow sites and also mussel recovery at high flow sites. These density-dependent grazer effects were were both non-linear and flow-dependent, with low abundance thresholds needed to suppress plant community recovery, and much higher levels needed to control mussel bed development. Our study suggests that consumer density and identity are key in regulating both plant and animal community recovery and that physical conditions can determine the functional forms of these consumer effects

    Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

    Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

    Addressing crises of order: judicial state-building in the wake of conflict

    Promoting the rule of law is vital for the success of domestic and international postconflict state-building efforts. Yet in post-conflict settings, non-state justice systems handle most disputes, retaining substantial autonomy and authority. Legal pluralism's importance, however, is rarely recognized and dramatically under-theorized. This thesis demonstrates that multiple justice systems can co-exist and contribute to the development of a democratic state bound by the rule of law. Domestic and international efforts, however, must be cognizant of the overarching legal pluralism paradigm that exists when trying to build the rule of law and tailor their strategies accordingly. By drawing on two divergent case studies, Timor-Leste and Afghanistan, this dissertation examines the conditions under which the rule of law can be advanced in post-conflict settings featuring a high degree of legal pluralism and substantial international involvement. Four distinct legal pluralism paradigms are proposed â combative, competitive, cooperative, and benign â in order to understand how legal pluralism functions in practice. Timor-Leste successfully advanced the rule of law because the major parties remained committed to democracy and developed institutions promoting accountability, inclusivity, and legality. The state meaningfully collaborated with key non-state actors. While the process was imperfect, Timorese state-officials effectively mediated between the international community and local-level figures. This contributed to the effective transformation of a competitive legal pluralist environment into a cooperative one. The international community largely reinforced these positive trends. Conversely, Afghanistan's post-2001 regime squandered the opportunity to build a democratic state bound by the rule of law. Simultaneously, it failed to mediate between the international community and the tribal and religious authorities essential for legitimate rule. Despite international actor's substantial influence, external aid did little good and was often counter-productive. These divergent approaches helps explain judicial state-building's failure and the corresponding slide from competitive into combative legal pluralism against the Taliban.</p
