This paper examines the relationship between crime rates and aggregate economic conditions for 57 small social areas. The principal analyses address a continuing controversy—are community crime rates
The impact of gun control and gun ownership levels on violence rates
What effects do gun control restrictions and gun prevalence have on rates of violence and crime? Data were gathered for all 170 U.S. cities with a 1980 population of at least 100,000. The cities were
Latent-variable models in criminological research: Applications and a generalization of Joreskog's LISREL model
This paper examines issues in LISREL models involving latent, or unobserved, variables. We discuss estimating parameters in multiple-indicator models, various approaches to assessing goodness of fit,
A swine dysentery model for evaluation of drug prophylaxis: efficacy of various drugs in the control of swine dysentery.
A swine dysentery (SD) model that produces consistent, homogeneous, and severe SD was used in 2 experiments to compare the prophylactic effectiveness of 5 commercially available swine feed additive

Oxytetracycline concentrations in plasma and lung of healthy and pneumonic calves, using two oxytetracycline preparations.
Drug concentrations in lung tissue and plasma pharmacokinetics of a long-acting preparation of oxytetracycline were compared with those of a standard preparation given to healthy and pneumonic calves and a difference in pharmacokinetic values was not observed.
A swine dysentery model for evaluation of drug prophylaxis: development of a model involving oral infection plus pen contamination.
A model has been developed that produces SD comparable with natural infections that are frequently encountered in commercial pig production facilities, and it produced consistent, homogeneous, and severe SD with 100% morbidity and 92% mortality.
Applications and a Generalization of Mimic Models to Criminological Research
This article examines models involving multiple causes of a single latent endogenous variable. Such models, known as MIMIC models, combine psychometric and econometric features into a single unifying
