Fired for Being Too Attractive

Journal of case studies (2014)

Mark A. Johnson James P. Jolly

Dr. James Knight had a small dental practice. One of his employees, Melissa Nelson, had worked for the facility for approximately ten years. Dr. Knight and Nelson became quite close and shared with each other a lot of personal information and even at times made comments about their sex lives. Dr. Knight’s wife also was an employee at the dental office and she suspected that her husband might be having an affair with Nelson. When Mrs. Knight learned that her husband and Nelson had been texting one another while he was out of town on a trip, she demanded that he terminate Nelson’s employment. Dr. Knight complied with his wife’s demands and discharged Nelson. She subsequently filed sex discrimination charges in an Iowa District Court. Dr. Knight knew he needed to contact his attorney to discuss whether they could win the case and if so how.

Can Changes in the Purchasing Managers’ IndexForetell Stock Returns? An Additional Forward-LookingSentiment Indicator

The Journal of Investing (2011)

Mark A. Johnson Kevin Watson

This article studies whether the Purchasing Managers’ Index (PMI) can lend itself usefully to the forecasting of future stock returns. Utilizing time-series regression analyses, we find a positive relationship between changes in PMI and stock returns. This suggests that optimism (pessimism) as indicated by changes in the PMI translate into higher (lower) subsequent stock returns. Additionally, after controlling for macroeconomic conditions such as the strength of the U.S. dollar, inflation, and the current state of the U.S. economy, these results persist. The results show PMI changes have a greater impact on the stocks of smaller market capitalization firms and industries such as precious metals, computer technology, textiles, and automobiles. The article examines how PMI’s forecasting role has evolved over time using rolling regressions and including changes in PMI as an additional factor in Fama and French’s popular three-factor model.

Perceiving and Acting in a World of Objects

Developmental Cognitive Neuroscience (2023)

Michelle de Haan Mark A. Johnson Iroise Dumontheil

Objects are special in sensory world since they are both recognized and manipulated. It is important to know what objects are, and where they are, in order to act on them. Neuroscience evidence suggests that these two “what and where” functions are computed by two different pathways: a ventral recognition pathway and a dorsal sensorimotor action pathway. A different approach to understanding the relation between dorsal and ventral stream processing is to examine developmental disorders in which one component is particularly affected. This approach has led to the proposal that there is a “dorsal stream vulnerability” across several developmental disorders. Bursts of high-frequency neural oscillations have been related to the binding of features to compose objects and to the retention of objects following occlusion. Recent studies have used these neural oscillations to study object processing in infants and may provide a direct marker for active representations of occluded objects in infants.

A Rejoinder to Thomas Shannon

Theological Studies (1997)

Mark A. Johnson

The A.'s note continue the discussion raised in this journal last year between himself and Thomas A. Shannon on the preimplantation embryo. Johnson is concerned that Shannon's manner of interpreting the biological data, incorrectly, he judges, leads him to deny the embryo's unity because of his misplaced dependence upon totipotency

Predicted and observed sizes of dystrophin in some patients with gene deletions that disrupt the open reading frame.

Journal of Medical Genetics (1992)

L. V. B. Nicholson Kate Bushby Mark A. Johnson Johan T. den Dunnen Ieke B. Ginjaar

Among 85 patients with Duchenne and Becker muscular dystrophy, 29 were found to have mutations which disrupted the open reading frame for dystrophin. Thus any dystrophin detected in this group of patients should consist of the severely truncated polypeptides that represent prematurely terminated translation products. Dystrophin was detected in blots from 17/29 biopsies and the observed sizes of the polypeptides were compared with predicted sizes calculated in two ways: if translation was terminated at the stop codon generated by each frameshifting deletion, and if the reading frame was restored and translation proceeded. In every case the observed size matched the size predicted on the basis of a restored reading frame. This was in accord with immunocytochemical labelling of scattered dystrophin positive fibres which were found on serial sections labelled with antibodies to both the rod and C-terminal domains. Thus analysis at the protein level supports genetic evidence of exon skipping as a mechanism which restores frameshifting mutations in some fibres.
