Some communication patterns observed in families using an identified patient as a scapegoat.

According to Vogel and Bell (I960), scapegoating is a social process in which tensions between or among group members are projected either onto a member of the group or onto an outsider. They suggest that the scapegoat serves the function of alleviating or channeling group tensions by taking the blame. On the basis of the intensive study of a small group of families, each with an emotionally disturbed child, and a matched sample of well families, none of which manifested any disturbance, Vogel and Bell (1960) suggest that scapegoating within their sample of families is characterized by the following features: the scapegoat is an identified patient (usually a child) who is in some way different or exceptional, discipline is inconsistent (especially with reference to the patient\u27s presenting problem) , tension and value-conflict exist between the parents, and affect-expression is minimal between the parents

The development of baryon asymmetry in the early universe

The development of an excess of baryons over antibaryons due to CP and baryon number violating reactions during the very early stages of the big bang is calculated in simple models using the Boltzmann equation. We show that it is necessary to solve the coupled Boltzmann equations in order to determine the final baryon number in any specific model

Elliptic flow from partially thermalized heavy-ion collisions

We study to what extent the measured elliptic flow at RHIC constrains viscous deviations from ideal hydrodynamics. We solve a toy model where only transverse momenta are thermalized while the system undergoes longitudinal free-streaming. We show that RHIC data exclude such a model and thus require fast 3-dimensional thermalization.Comment: 4 pages (incl. 2 postscript figures); uses espcrc1.sty (included in submission). Talk given at Quark Matter 2002, Nantes, June 18-24, 2002, to appear in the proceedings in Nucl. Phys.

Conversion detection for improved online ad selection

Online ads sometimes continue unchanged even after the ad had resulted in a conversion, e.g., after a user has purchased the advertised product. Many users find such continued presence of the ad annoying. Also, not refreshing the ad with a different product represents lost revenue for the website publisher and the ad network. This disclosure describes techniques to detect if the user has purchased a given product by analyzing, with user consent and permission, user data such as emails and other data. Upon detecting conversion, display of ads relating to the product or similar products is discontinued

Physiological response to groundwater depth varies among species and with river flow regulation

We investigated the physiological response of two native riparian tree species (Populus fremontii and Salix gooddingii) and one exotic species (Tamarix chinensis) to groundwater availability along gradients of depth to groundwater at two rivers in Arizona. Depth to groundwater (DGW) at the dam-regulated Bill Williams River (BWR) was relatively constant and shallow (,4 m). Populus fremontii at BWR did not experience reduced water availability at deeper groundwater depths, as evidenced by high predawn water potential. However, leaf gas exchange of P. fremontii was sensitive to high vapor pressure deficit where surface flow was ephemeral at BWR. Lower predawn water potentials of S. gooddingii at BWR suggested reduced water availability at deeper groundwater depths, but these reductions did not adversely affect net photosynthetic rate. Along the range of depth to groundwater at BWR, all three species suffered little canopy dieback, and dieback was not related to depth to groundwater. Depth to groundwater at the free-flowing Hassayampa River (HRP) was much greater and declined more rapidly in the ephemeral reaches than at BWR. Both P. fremontii and S. gooddingii experienced reduced water availability at deeper groundwater depths at HRP, as evidenced by lower predawn water potential. Both species also experienced reduced leaf gas exchange at deeper groundwater depths. Canopy dieback of all species was higher at HRP than at BWR and increased with increasing DGW, especially when DGW fell below 3 m. There was evidence to support branch sacrifice in these three riparian tree species as a means of improving water status in the surviving shoot. However, branch sacrifice was insufficient to prevent mortality in some of the native trees where DGW fell below 3 m at HRP. In contrast to the native species, T. chinensis showed no change in water availability, leaf gas exchange, or canopy dieback with increasing DGW at either river. Leaf gas exchange was lower and dieback was greater for T. chinensis at HRP where depth to groundwater was greater than at BWR, but there was no mortality at either river. Our results show that deep groundwater is more detrimental to the physiological condition of P. fremontii and S. gooddingii than it is to T. chinensis. Also, the pronounced differences in DGW and tree physiological performance between BWR and HRP suggest that dam regulation can increase water availability to mature trees in some desert riparian ecosystems. Finally, our study also provides estimates of the range of DGW that can maintain healthy, mature P. fremontii and S. gooddingii trees

Facial Onset Sensory and Motor Neuronopathy: A Case Series and Literature Review

Introduction: Facial Onset Sensory and Motor Neuronopathy (FOSMN) typically presents with paresthesias in the trigeminal nerve distribution and weakness that progresses rostro-caudally. Objective: To present two new cases of FOSMN, summarize the current literature, and address areas for future study. Methods: Observational data was collected from two patients with FOSMN from our institution. A literature review of FOSMN was completed using PubMed. Results: We identified 100 cases of FOSMN, including our two new cases. 93% presented with facial paresthesias. 97% had bulbar symptoms. Five had family history of ALS. Abnormal Blink reflex was most common on EMG/NCS. CSF was typically normal, but a rare severe case showed elevated protein. Mutations included: TARDBP, OPMD, D90A-SOD1, CHCHD10, VCP, and SQSTM1. Neuropathological studies showed neurodegenerative changes without inflammation. Some cases have reported transient stabilization or improvement to immunomodulatory therapy. Case Reports: A 72-year-old man presented with right-sided trigeminal paresthesias that progressed in a rostro-caudal fashion, dysphagia, and hand weakness. He died 4-5 years after symptom onset. A 69-year-old man presented with left-sided jaw paresthesias, dysphagia and dysarthria. He was trialed on IVIG for 1.5 years without improvement and died 2.6 years after symptom onset. Conclusion: FOSMN is a rare disorder with a unique clinical and electrophysiological phenotype. The pathophysiology has been associated with neurodegeneration and multiple gene mutations have correlated to FOSMN. Some reports suggest transient response to immunomodulatory therapy, though prospective studies are lacking. CSF protein elevation may be seen in severe disease. Future studies will help further elucidate the approach to diagnosis, treatment, and prognostic counseling (biomarkers). &nbsp
