Moving beyond panaceas in fisheries governance.

In fisheries management-as in environmental governance more generally-regulatory arrangements that are thought to be helpful in some contexts frequently become panaceas or, in other words, simple formulaic policy prescriptions believed to solve a given problem in a wide range of contexts, regardless of their actual consequences. When this happens, management is likely to fail, and negative side effects are common. We focus on the case of individual transferable quotas to explore the panacea mindset, a set of factors that promote the spread and persistence of panaceas. These include conceptual narratives that make easy answers like panaceas seem plausible, power disconnects that create vested interests in panaceas, and heuristics and biases that prevent people from accurately assessing panaceas. Analysts have suggested many approaches to avoiding panaceas, but most fail to conquer the underlying panacea mindset. Here, we suggest the codevelopment of an institutional diagnostics toolkit to distill the vast amount of information on fisheries governance into an easily accessible, open, on-line database of checklists, case studies, and related resources. Toolkits like this could be used in many governance settings to challenge users' understandings of a policy's impacts and help them develop solutions better tailored to their particular context. They would not replace the more comprehensive approaches found in the literature but would rather be an intermediate step away from the problem of panaceas.

Modeling the Spatial Dynamics of International Tuna Fleets.

We developed an iterative sequential random utility model to investigate the social and environmental determinants of the spatiotemporal decision process of tuna purse-seine fishery fishing effort in the eastern Pacific Ocean. Operations of the fishing gear mark checkpoints in a continuous complex decision-making process. Individual fisher behavior is modeled by identifying diversified choices over decision-space for an entire fishing trip, which allows inclusion of prior and current vessel locations and conditions among the explanatory variables. Among these factors are vessel capacity; departure and arrival port; duration of the fishing trip; daily and cumulative distance travelled, which provides a proxy for operation costs; expected revenue; oceanographic conditions; and tons of fish on board. The model uses a two-step decision process to capture the probability of a vessel choosing a specific fishing region for the first set and the probability of switching to (or staying in) a specific region to fish before returning to its landing port. The model provides a means to anticipate the success of marine resource management, and it can be used to evaluate fleet diversity in fisher behavior, the impact of climate variability, and the stability and resilience of complex coupled human and natural systems.

Effects of estrus, estrogen-progesterone priming, and vaginal stimulation on tonic immobility, dorsal immobility, and lordosis in the female rat.

Three complex inhibitory responses, tonic immobility, the dorsal immobility response, and lordosis, were studied in the intact female rat during estrus and diestrus and in ovariectomized rats with estrogen-progesterone treatment or controls. In each condition, the effects of vaginal-cervical stimulation were also studied. The results of two experiments indicate that estrus and estrogen-progesterone treatment significantly potentiate lordosis and the dorsal immobility response with or without vaginal-cervical stimulation. Tonic immobility was also potentiated by estrus and estrogen-progesterone treatment, but only if vaginal-cervical stimulation was applied. Vaginal-cervical stimulation potentiated both tonic immobility and the dorsal immobility response, but not lordosis, which was already at a high level.

Emotional memories: the relationship between age of memory and the corresponding psychophysiological responses.

The recollection of emotional memories has been used as a method of emotion induction for much of the research concerning the psychophysiological sequelae of emotions. The instructions used in most of these investigations have simply required the participants to recollect or imagine an emotional memory, with no constraint being placed on the age of the memory. Research has indicated that the specific instructions for inducing emotions can have a profound effect on the resulting patterns of psychophysiological arousal. The present investigation concerned whether the age of the emotional memory has an influence on the resulting psychophysiological arousal. Heart rate and skin conductance was recorded from 10 female graduate students while they recollected emotional memories concerning mirth and anger. The results indicated a significant positive correlation between skin conductance and age of both the angry (0.6395) and the mirthful (0.8460) memories. The results are discussed and explained within the framework of the somatic marker hypothesis and the spreading activation model of memories.

Public perceptions of environmental quality: a survey study of beach use and perceptions in Los Angeles County.

Despite documented successes in the battle to clean up the coastal waters of Southern California, Los Angeles County residents continue to view the ocean more as a place of pollution than a vibrant and healthy place for bathing and swimming. This study shows that residents of Los Angeles County tend to hold perceptions of marine water quality that are at odds with data on bacteriological measures of water quality collected by local sanitation districts (and reported by not-for-profit Heal the Bay). Summary results of a survey of 400 randomly chosen households in Los Angeles County are given. Respondents were asked about their beach use and perceptions of environmental quality: both coastal water quality and air quality. The results suggest that perceptions of coastal water quality may be influenced less by "current coastal education campaigns" and more by the media and other factors.
