No full textPhotocopy of letter written by Jitzchak Eisik Horowitz to his son on his wedding day (1840) describing the family ancestors, including the Vilna Gaon and rabbis from Worms, Strassburg, Krakow among others. Translated from the Hebrew in 1934 by Dr. M. N. Nathan, Rabbi of the Hamburg Jewish community, who certified the family letter was the possession of Maurice Ruebener.Ralph Ruebnerdigitize

Empirical validation of the Horowitz Multiple Systemic Infectious Disease Syndrome Questionnaire for suspected Lyme disease
No full textMaryalice Citera,1 Phyllis R Freeman,2 Richard I Horowitz2 1Department of Psychology, State University of New York at New Paltz, New Paltz, NY, 2Hudson Valley Healing Arts Center, Hyde Park, NY, USA Purpose: Lyme disease is spreading worldwide, with multiple Borrelia species causing a broad range of clinical symptoms that mimic other illnesses. A validated Lyme disease screening questionnaire would be clinically useful for both providers and patients. Three studies evaluated such a screening tool, namely the Horowitz Multiple Systemic Infectious Disease Syndrome (MSIDS) Questionnaire. The purpose was to see if the questionnaire could accurately distinguish between Lyme patients and healthy individuals.Methods: Study 1 examined the construct validity of the scale examining its factor structure and reliability of the questionnaire among 537 individuals being treated for Lyme disease. Study 2 involved an online sample of 999 participants, who self-identified as either healthy (N=217) or suffering from Lyme now (N=782) who completed the Horowitz MSIDS Questionnaire (HMQ) along with an outdoor activity survey. We examined convergent validity among components of the scale and evaluated discriminant validity with the Big Five personality characteristics. The third study compared a sample of 236 patients with confirmed Lyme disease with an online sample of 568 healthy individuals.Results: Factor analysis results identified six underlying latent dimensions; four of these overlapped with critical symptoms identified by Horowitz – neuropathy, cognitive dysfunction, musculoskeletal pain, and fatigue. The HMQ showed acceptable levels of internal reliability using Cronbach’s coefficient alpha and exhibited evidence of convergent and divergent validity. Components of the HMQ correlated more highly with each other than with unrelated traits.Discussion: The results consistently demonstrated that the HMQ accurately differentiated those with Lyme disease from healthy individuals. Three migratory pain survey items (persistent muscular pain, arthritic pain, and nerve pain/paresthesias) robustly identified individuals with verified Lyme disease. The results support the use of the HMQ as a valid, efficient, and low-cost screening tool for medical practitioners to decide if additional testing is warranted to distinguish between Lyme disease and other illnesses.

The Fate of Onsite Septic System Nitrogen Discharges in Groundwater of the Hood Canal Basin
No full textNitrogen loading from onsite septic systems (OSSs) may degrade the ecological health of aquatic systems by causing or accentuating eutrophication leading to hypoxia or anoxia. OSSs do not typically remove nitrogen within the septic tank; therefore, denitrification is the primary mechanism controlling nitrogen loading from OSSs to surface water systems. Hood Canal, located in the Puget Sound region of Washington, has been severely affected by low dissolved oxygen concentrations due to excess nitrogen loading. Onsite septic systems are the primary wastewater treatment process in this watershed and may be an important source of nitrogen to Hood Canal.
Horowitz describes a study in which she determined how much denitrification occurred in OSS effluents in the Hood Canal basin, a glacially-formed, geologically complex system. Shallow sampling wells (0.5 – 2 m) were installed around five OSS drainfields and deep sampling wells (6 m) at one OSS drainfield. Well samples were analyzed for nitrogen, chloride, bromide, and dissolved organic carbon concentrations. The extent of nitrogen reduction varied among the field sites and between two years at one field site. A study site, located in a riparian floodplain, was found to have nearly complete denitrification. Shoreline sites, located near rocky intertidal zones, were found to have little denitrification. And sites located in upland areas were found to have partial denitrification.William D. Ruckelshaus Center. Washington State University
Dynamic time series binary choice
No full textThis paper considers dynamic time series binary choice models. It shows in a time series setting the validity of the dynamic probit likelihood procedure when lags of the dependent binary variable are used as regressors, and it establishes the asymptotic validity of Horowitz' smoothed maximum score estimation of dynamic binary choice models with lags of the dependent variable as regressors. The latent error is explicitly allowed to be correlated. It turns out that no long-run variance estimator is needed for the validity of the smoothed maximum score procedure in the dynamic time series framework. One novel aspect of this paper is a proof that weak dependence properties hold for dynamic binary choice models with correlated errorsbinary choice; near epoch dependence; asymptotic theory; smoothed maximum score
Dynamic time series binary choice
No full textThis paper considers dynamic time series binary choice models. It proves near epoch dependence and strong mixing for the dynamic binary choice model with correlated errors. Using this result, it shows in a time series setting the validity of the dynamic probit likelihood procedure when lags of the dependent binary variable are used as regressors, and it establishes the asymptotic validity of Horowitz?smoothed maximum score estimation of dynamic binary choice models with lags of the dependent variable as regressors. For the semiparametric model, the latent error is explicitly allowed to be correlated. It turns out that no long-run variance estimator is needed for the validity of the smoothed maximum score procedure in the dynamic time series framework.
