ABSTRACT
OBJECTIVE: We examine relationships between workplace harassment (WH) and onset of health conditions over a 23-year period. METHODS: Participants were surveyed at seven points between 1997-2006 and again in 2020. Regression analyses (n = 921) assessed effects of chronic WH exposure on onset or recent health conditions by 2020. RESULTS: Growth mixture modeling revealed infrequent and chronic classes of generalized workplace harassment (GWH; 33.39% chronic) and sexual harassment (SH; 32.32% chronic). Prevalence of health conditions ranged from 3.71% for myocardial infarction to 43.06% for hypertension. Analysis via propensity score matching showed chronic WH class membership increased odds of coronary heart disease (GWH, odds ratio [OR] = 3.42, P < 0.05), arthritic/rheumatic conditions (SH, OR = 1.56, P < 0.05), and recent migraine (SH, OR = 1.68, P < 0.05). CONCLUSIONS: Workplace harassment is associated with coronary heart disease, arthritic/rheumatic conditions, and migraine. Worker health can be protected through strengthening and enforcing organizational and social antiharassment policies and laws.

A new thermometric sensor, which is a transistor (OC71), has been introduced to follow thermometric titrations successfully to clear end points. The sensor was suitable in both normal and differential modes of titration. It is possible to titrate down to 1.32micromol of HCl and 26.4micromol of H(3)BO(3)in a final 20ml solution with accuracy and precision of 1%, 2.2% and 1.4%, 2.2%, respectively. The sensor, in association with a pH glass electrode, was used for the determination of pK values of some well established weak acids such as, acetic acid (4.77), phosphoric acid (pK(1)=2.18, pK(2)=7.20 and pK(3)=12.32) as well as for a very weak acid of uncertain pK values H(3)BO(3) (pK(1)=9.20, pK(2)=12.7 and pK(3)=13.80). The sensor was also examined for kinetic catalytic determination of iron(III) in water, milk and pharmaceuticals.
