Social Context-Dependent Activity In Marmoset Frontal Cortex Populations During Natural Conversations, Samuel U. Nummela, Vladimir Jovanovic, Lisa De La Mothe, Cory T. Miller

Psychology Faculty Research

Communication is an inherently interactive process that weaves together the fabric of both human and nonhuman primate societies. To investigate the properties of the primate brain during active social signaling, we recorded the responses of frontal cortex neurons as freely moving marmosets engaged in conversational exchanges with a visually occluded virtual marmoset. We found that small changes in firing rate (∼1 Hz) occurred across a broadly distributed population of frontal cortex neurons when marmosets heard a conspecific vocalization, and that these changes corresponded to subjects' likelihood of producing or withholding a vocal reply. Although the contributions of individual neurons were …

Smoking, Depression, And Hospital Costs Of Respiratory Cancers: Examining Race And Sex Variation, Baqar A. Husaini, Robert S. Levine, Phillip Lammers, Pam Hull, Meggan Novotny, Majaz Moonis

Center for Prevention Research Publications

Objective To investigate the effect of smoking and depression on hospital costs for lung cancer (LC).

Methods We extracted data on depression, smoking history, demographics, and hospital charges for patients with respiratory cancers (ICD-9 codes 161–163, 165) from the 2008 Tennessee Hospital Discharge Data System. The sample (n=6665) was mostly white (86%) and male (57%). Age-adjusted rates were developed in accordance with Centers for Disease Control and Prevention methods, and hospital costs were compared for patients with LC with versus without depression and a smoking history.

Results Three findings (P<0.001) emerged: (1) the LC rate was higher among blacks than among whites, and higher among men than among women; (2) while 66% of LC patients smoked (more men than women without racial variation), 24% had depression (more females and whites were depressed); (3) the LC hospital cost was 54% higher than the non-LC hospital cost, and this cost doubled for patients with LC with depression and smoking versus those without such characteristics.

Conclusion While LC is more prevalent among …

Socioeconomic, Environmental, And Geographic Factors And Us Lung Cancer Mortality, 1999–2009, Maria Carmenza Mejia De Grubb, Barbara J. Kilbourne, Katy Kilbourne, Michael Langston, Lisa Gittner, Roger J. Zoorob, Robert S. Levine

Sociology Faculty Research

Background The American Cancer Society estimates that about 25% of all US cancer deaths will be due to lung cancer – more than from cancers of the colon, breast, and prostate combined.

Methods We ascertained county-level age-adjusted and age-specific death rates and 95% confidence intervals from the Centers for Disease Control and Prevention Compressed Mortality File. Multiple regression analyses were used to estimate the strength and direction of relationships between county poverty, smoking, fine particulate matter (PM2.5) air pollution, and US Census divisions and race- and sex-specific lung cancer deaths.

Results Poverty, smoking, and particulate matter air pollution were positively …

Collective Litigation Of Environmental Rights In Colombia: An Empirical Study, Ángela María Páez-Murcia, Everaldo Lamprea-Montealegre, Catalina Vallejo-Piedrahita

Public Administration Faculty Research

This paper presents the results of an empirical study that systematized environmental judicial opinions handed down by Colombia’s highest administrative Court —Consejo de Estado— over a 17-year period (1998-2015). Thanks to a research grant, the authors and a team of coders systematized, using state-of-the art content analysis methodologies, more than 250 opinions handed down by Colombia’s highest administrative Court. The results presented in this paper show the most important trends of collective environmental litigation in Colombia: types of plaintiffs and defendants; type of environmental resources involved in the case; plaintiffs’ success rates; most litigious regions and cities; overall effects of …
