The competitive environment of pay per view

A field test was used to assess the efficacy of pay per view (PPV) and how PPV compared to pay cable programming and vidéocassette recorder (VCR) rentals. Owners of VCRs perceived PPV differently than did nonowners of VCRs. Differences were observed along the dimensions of convenience, ease of operation, control, and perceived value. PPV perceptions did not vary by those currently subscribing to pay cable.     

不妨除去银行的光芒

Thirty-plus years ago, when I was a graduate student in economics, only the least ambitious of my class-mates sought careers in the financial world.

Forced suffocation of infants with baby wipes: a previously undescribed form of child abuse

BACKGROUND: Foreign body aspiration in children is commonly seen in emergency departments and carries a significant mortality. Abusive foreign body suffocation is not well described. METHODS: We present a case-series of four infants who presented with aspiration of a baby wipe. RESULTS: Each child was found to be a victim of child physical abuse with substantial morbidity and mortality associated with the aspiration of the wipe and associated injuries. CONCLUSIONS: We recommend that infants who present with a baby wipe aspiration should be considered as likely victims of child abuse and physicians should evaluate each infant for associated injuries of the oropharynx, skin, skeleton, and head.
