Judgment time and sensory ability of inspector

Introduction: The ischemic stroke is one of the main causes of death and disability in Brazil. Among the main risk factors are age, atrial fibrillation (AF), diabetes, dyslipidemia and physical inactivity. The main etiology of stroke is cardioembolic, resulting in obstruction of the cerebral arteries by a thrombus of cardiac origin. The artery most affected in ischemic strokes is the middle cerebral artery. The stroke has main characteristics, with emphasis on the sudden onset of symptoms, involvement of a focal area, ischemia caused by obstruction of a vessel and neurological deficits depending on the affected area. Graphesthesia is defined as a cutaneous sensory ability to recognize letters or numbers traced on the skin. The loss of this sensory ability is known as agraphesthesia. Case Report: M.A.F.O. female, 78a, arrived at the UPA complaining of mental confusion. Patient denies previous stroke. Personal history of systemic arterial hypertension. Upon physical examination, the patient was conscious, self and disoriented and inattentive. He was able to repeat and evoke words, without measurable motor déficits. Left upper limb with agraphestesia. Computed tomography was requested, which showed an extensive hypodense area in the right parietoccipital region, which leads to the erasure of the furrows between the adjacent gyres, which may correspond to a recent ischemic event. Magnetic resonance imaging, diffusion-restricted area with correspondence on the ADC map, located in the right temporoparietal region inferring an acute ischemic event. An electrocardiogram was also requested, which showed an irregular rhythm, characteristic of atrial fibrillation, resulting in a diagnostic hypothesis of cardioembolic ischemic stroke. Discussion: The involvement of post-central ischemic gyrus lesions may correspond to paresthesia, anesthesia, hypoesthesia; the involvement of secondary and terciary areas of sensitivity in the upper parietal lobe, especially in the active movements of the hand and in the modalities of integrated sensitivity, their lesions may be clinically affected by: apraxias, dysgraphias, hemineglect, agraphestesia, stereoagnosia and spacial disorientation.

The emergence of crowdsourcing as an important mode of information production has attracted increasing research attention. In this article, the authors review crowdsourcing research in the data management field. Most research in this domain can be termed tasked-based, focusing on micro-tasks that exploit scale and redundancy in crowds. The authors' review points to another important type of crowdsourcing – which they term observational – that can expand the scope of extant crowdsourcing data management research. Observational crowdsourcing consists of projects that harness human sensory ability to support long-term data acquisition. The authors consider the challenges in this domain, review approaches to data management for crowdsourcing, and suggest directions for future research that bridges the gaps between the two research streams.

Sensory Ability

AbstractJellyfish locomotion and orientation have been studied in the past both in the laboratory, testing mostly small jellyfish, and in the field, where it was impossible to control the seawater currents. Utilizing an outdoor water flume, we tested the locomotion of jellyfish when swimming against and with currents of up to 4.5 cm s−1. We used adult jellyfish from two of the most abundant species in the eastern Mediterranean, Rhopilema nomadica and Rhizostoma pulmo, and measured their pulsation frequency and swimming speed relative to the water. While pulsation frequency was not affected by the water velocity, jellyfish swam faster against the current than with it. This finding suggests that jellyfish possess a sensory ability, whose mechanism is currently unknown, enabling them to gauge the flow and react to it, possibly in order to reduce the risk of stranding.
