On the Margulis constant for Kleinian groups, I curvature
The Margulis constant for Kleinian groups is the smallest constant such
that for each discrete group and each point in the upper half space
, the group generated by the elements in which move less
than distance c is elementary. We take a first step towards determining this
constant by proving that if is nonelementary and discrete
with parabolic or elliptic of order , then every point in
is moved at least distance by or where
. This bound is sharp

Coping as a Mediator between Symptom Burden and Distress in Lung Cancer Patients
Lung cancer is considered the leading cause of cancer death worldwide. An estimated 224,390 new cases of lung cancer are expected to be diagnosed and 158,080 Americans are expected to die from lung cancer in 2016 (National Institutes of Health, 2016; Siegel, Miller, & Jemal, 2016). Lung cancer patients also report the highest levels of psychological distress and symptom burden than any other forms of cancer (Linden, Vodermaier, MacKenzie, & Greig, 2012). Given the prevalence and impact of lung cancer, it is imperative to address the emotional toll this diagnosis can have on those suffering with the disease to develop helpful strategies for those coping with lung cancer. The goal of this study is to determine how much lung cancer patients’ symptom burden affects their level of distress, and how much of this effect is mediated by approach and/or avoidance coping styles. Adults (N = 109, 57% female,) with an average age of 67 (SD = 10.1) diagnosed with lung cancer completed a questionnaire assessing for physical and psychological functioning at two medical centers in Southern California. Results: There was a significant positive relationship between total symptom burden and distress. Avoidance coping was a significant mediator of the relationship between total symptom burden and distress. Approach coping was not a significant mediator of this relationship. Conclusions: Results suggest that a patient experiences more distress as his/her symptom burden increases, and this effect is partially explained by engaging in avoidant coping. Therefore, it is important to find ways to help patients cope more effectively to reduce their levels of stress. The findings of this study show the importance of continued research to find effective coping strategies and as well to inhibit patients from engaging in an avoidant coping style
