We studied three patients with spontaneous dorsal mesencephalic hemorrhages. One patient had Parinaud's syndrome with a unilateral hemorrhage confined to the rostral tectal plate. The second patient had vertical gaze palsy, skew deviation, and bilateral Horner's syndrome due to a unilateral hemorrhage that involved the superior colliculus and extended anteriorly into the midbrain tegmentum and inferiorly to the rostral dorsal pons. The third patient had a hemorrhage in the caudal tectal plate, with bilateral fourth cranial nerve palsies, unilateral Horner's syndrome, and ataxia. There was hydrocephalus due to obstruction of the aqueduct in two patients. The patients recovered, but with some degree of disability.
This study investigates whether organisational commitment is associated with organisations‘CSR performance within sustainability aspects of their internal process. A structural equation model (SEM) tested two sequential direct associations between: (1) senior management employees‘ affective and continuance organisational commitment and organisations‘ conventional value-creating internal processes; (2) conventional value-creating internal processes and organisations‘ CSR performance within sustainability value-creating internal process. The SEM results show an indirect association between affective commitment and CSR performance within sustainability value-creating internal process, which is mediated by the conventional value-creating internal processes. The findings support an integrated sustainability internal process within a sustainability balanced scorecard (SBSC) as depicted in Kaplan and Norton‘s strategy map. Organisations may develop internal processes that promote CSR outcome characteristics when employees possess higher levels of affective organisational commitment. Future research could investigate a broader range of environmental outcomes within CSR performance.
A small satellite in a low-Earth orbit (e.g., approximately a 300 to 400 km altitude) has an orbital velocity in the range of 8.5 km/s and completes an orbit approximately every 90 minutes. For a satellite with minimal attitude control, this presents a significant challenge in obtaining multiple images of a target region. Presuming an inclination in the range of 50 to 65 degrees, a limited number of opportunities to image a given target or communicate with a given ground station are available, over the course of a 24-hour period. For imaging needs (where solar illumination is required), the number of opportunities is further reduced. Given these short windows of opportunity for imaging, data transfer, and sending commands, scheduling must be optimized. In addition to the high-level scheduling performed for spacecraft operations, payload-level scheduling is also required. The mission requires that images be post-processed to maximize spatial resolution and minimize data transfer (through removing overlapping regions). The payload unit includes GPS and inertial measurement unit (IMU) hardware to aid in image alignment for the aforementioned. The payload scheduler must, thus, split its energy and computing-cycle budgets between determining an imaging sequence (required to capture the highly-overlapping data required for super-resolution and adjacent areas required for mosaicking), processing the imagery (to perform the super-resolution and mosaicking) and preparing the data for transmission (compressing it, etc.). This paper presents an approach for satellite control, scheduling and operations that allows the cameras, GPS and IMU to be used in conjunction to acquire higher-resolution imagery of a target region.
Nonbacterial thrombotic endocarditis (NBTE) is a presentation of an occult malignancy. The clinical, laboratory and postmortem findings of a 44-year-old man with osteopetrosis and NBTE are reported. A small apical bronchogenic carcinoma was found on postmortem examination. A thorough search for malignancy should be made in patients with unexplained cerebral emboli, especially if hematologic abnormalities are present. There is presently no evidence that anticoagulation or other treatment is beneficial.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
