"Voyage through death/to life upon these shores": the living dead of the Middle Passage

While historical studies of the Atlantic slave trade have amply demonstrated the magnitude of slave mortality during the Middle Passage, only recently have they started to examine how the captives might have endured and coped with this traumatic experience. Although it constitutes a major topos in African diasporic culture, the Middle Passage has only occasionally been represented directly and in details in novels and in films. This article examines three recent narratives of the Middle Passage, Fred D'Aguiar's novel Feeding the Ghosts (1998), Guy Deslauriers's film Passage du milieu (2000), and Stephanie Smallwood's historical study Saltwater Slavery: A Middle Passage from Africa to American Diaspora (2007). Beyond their individual poetic, aesthetic, and scholarly qualities, what is most striking about these three texts is that they all use the figure of the living dead in order to explore the captives' experience of the transatlantic journey. If the ghastly quality of the living dead powerfully captures the life-threatening material and physical conditions the captives endured on the voyage, its dual, liminal character also allows D'Aguiar, Deslauriers, and Smallwood to represent the metaphysical, psychological, social, and cultural journey they were forced to undertake. Through their use of the trope of the living dead, these three texts show that if death is indeed a central aspect of the experience of the Middle Passage, it impacts the captives in ways that go well beyond the issue of mortality.

Transferring control demands across incidental learning tasks - Stronger sequence usage in serial reaction task after shortcut option in letter string checking

After incidentally learning about a hidden regularity, participants can either continue to solve the task as instructed or, alternatively, apply a shortcut. Past research suggests that the amount of conflict implied by adopting a shortcut seems to bias the decision for vs. against continuing instruction-coherent task processing. We explored whether this decision might transfer from one incidental learning task to the next. Theories that conceptualize strategy change in incidental learning as a learning-plus-decision phenomenon suggest that high demands to adhere to instruction-coherent task processing in Task 1 will impede shortcut usage in Task 2, whereas low control demands will foster it. We sequentially applied two established incidental learning tasks differing in stimuli, responses and hidden regularity (the alphabet verification task followed by the serial reaction task, SRT). While some participants experienced a complete redundancy in the task material of the alphabet verification task (low demands to adhere to instructions), for others the redundancy was only partial. Thus, shortcut application would have led to errors (high demands to follow instructions). The low control demand condition showed the strongest usage of the fixed and repeating sequence of responses in the SRT. The transfer results are in line with the learning-plus-decision view of strategy change in incidental learning, rather than with resource theories of self-control.

First-passage and escape problems in the Feller process

The Feller process is an one-dimensional diffusion process with linear drift and state-dependent diffusion coefficient vanishing at the origin. The process is positive definite and it is this property along with its linear character that have made Feller process a convenient candidate for the modeling of a number of phenomena ranging from single-neuron firing to volatility of financial assets. While general properties of the process have long been well known, less known are properties related to level crossing such as the first-passage and the escape problems. In this work we thoroughly address these questions.

Editorial: Serial Fecal Calprotectin and Lactoferrin Measurements for Early Diagnosis of Pouchitis After Proctocolectomy for Ulcerative Colitis: Is Pouchoscopy No Longer Needed?

This editorial discusses the role of serial measurements of fecal calprotectin or fecal lactoferrin for the early detection of pouchitis in patients with ulcerative colitis having undergone procto-colectomy with ileo-pouch-anal anastomosis. Furthermore, the role of fecal calprotectin and fecal lactoferrin for the monitoring of pouchitis is highlighted.

Orofacial pain of cardiac origin, serial of clinical cases

Objective: To determine the clinical characteristics of the orofacial pain of cardiac origin in patients visited when doing a treadmill exercise test, at the cardiology service of the Can Ruti Hospital in Badalona (Barcelona, Spain). Study design: The sample of that study included thirty patients visiteding when doing a treadmill exercise test, at the cardiology service. The questionnaire has been asked to a sample of 30 patients. Results: Eleven of the 30 patients included in this study presented craniofacial pain before or during the cardiac seizure. The location of the pain was bilateral, non-irradiated at the mandible in all cases. The intensity of the pain was from slight to severe. The frequency of the appearance of the pain was paroxysmal in 8 cases and constant in three cases, and the duration was from a few hours to a maximum of 14 days. Discussion: The cardiac pain in craniofacial structures is usually bilateral, compared to odontogenic pain which is always unilateral. The pain of cardiac origin is considered atypical because of its location, but about the 10 % of the cases, the cardiac ischemia has its primary manifestation in orofacial structures. Conclusions: Eleven patients referred a bilateral non-irradiated mandibular pain, with intensity from slight to severe, and with a paroxystic frequency in eight cases and a constant frequency in three cases. Just one patient referred pain during the treadmill exercise test. In all cases the pain disappeared after the cardiac surgery or the administration of vasodilators.
