Humor and Laughter may Influence Health. I. History and Background
Mary Payne Bennett,Cecile A. Lengacher
Evidence-Based Complementary and Alternative Medicine , 2006, DOI: 10.1093/ecam/nek015
Abstract: Articles in both the lay and professional literature have extolled the virtues of humor, many giving the impression that the health benefits of humor are well documented by the scientific and medical community. The concept that humor or laughter can be therapeutic goes back to biblical times and this belief has received varying levels of support from the scientific community at different points in its history. Current research indicates that using humor is well accepted by the public and is frequently used as a coping mechanism. However, the scientific evidence of the benefits of using humor on various health related outcomes still leaves many questions unanswered.

Humor and Laughter May Influence Health: II. Complementary Therapies and Humor in a Clinical Population
Mary Payne Bennett,Cecile Lengacher
Evidence-Based Complementary and Alternative Medicine , 2006, DOI: 10.1093/ecam/nel014
Abstract: Our results support a connection between sense of humor and self-reported physical health, however, it is difficult to determine the relationship to any specific disease process. Whereas relationships between sense of humor and self-reported measures of physical well-being appear to be supported, more research is required to determine interrelationships between sense of humor and well-being.

Abstract: Post-Traumatic Stress Disorder (PTSD) is a prevalent, disabling anxiety disorder. This prospective cohort study reports on a new exposure-based therapy known as Accelerated Resolution Therapy (ART ?) that incorporates the use of eye movements administered in a brief treatment period (1–5 one-hour sessions within three weeks). Eighty adults aged 21–60 years with symptoms of PTSD were recruited from the Tampa Bay area. The ART-based psychotherapy was designed to minimize anxiety and body sensations associated with recall of traumatic memories and to replace distressing images with favorable ones. Participants’ mean age was 40 years, 77% were female, and 29% were Hispanic. Participants underwent a median of three ART sessions, 66 of 80 (82.5%) completed treatment, and 54 of 66 (81.8%) provided 2-month follow-up data. Mean scores pre- and post-ART and at 2-month follow-up were: PTSD Checklist: 54.5 ± 12.2 vs. 31.2 ± 11.4 vs. 30.0 ± 12.4; Brief Symptom Inventory: 30.8 ± 14.6 vs. 10.1 ± 10.8 vs. 10.1 ± 12.1; Center for Epidemiologic Studies Depression Scale: 29.5 ± 10.9 vs. 11.8 ± 11.1 vs. 13.5 ± 12.1; Trauma Related Growth Inventory-Distress scale: 18.9 ± 4.1 vs. 7.4 ± 5.9 vs. 8.2 ± 5.9 ( p < 0.0001 for all pre-ART vs. post-ART and 2-month comparisons). No serious adverse events were reported. ART appears to be a brief, safe, and effective treatment for symptoms of PTSD.
Alcohol Mixed with Energy Drinks: Consumption Patterns and Motivations for Use in U.S. College Students
Cecile A. Marczinski
International Journal of Environmental Research and Public Health , 2011, DOI: 10.3390/ijerph8083232
Abstract: Binge drinking in college students is widespread and known to cause significant harms and health hazards for the drinker. One factor that may be exacerbating hazardous drinking in young people is the new popular trend of consuming alcohol mixed with energy drinks (AmED). However, rates of AmED use and motivations for AmED consumption in college students have not been well established. In this study, 706 undergraduate college students from a university in the United States participated in a web-based survey that queried self-reported alcohol, energy drink, and AmED use. In addition, motivations for using AmEDs were assessed. The results indicated that for all participants, 81% reported that they have tried at least one energy drink in the past and 36% reported consumption of at least one energy drink in the past 2 weeks. Alcohol consumption patterns were similar to findings from U.S. national surveys of college drinking, as 37% of respondents were classified as binge drinkers and 23% abstained from drinking. In the whole sample (including the alcohol abstainers), 44% reported trying AmED at least once and 9% reported AmED consumption at least once in the past 2 weeks. 78% of respondents agreed with the statement that AmEDs appeal to underage drinkers. When AmED users were asked about various motivations for consuming AmEDs, users reported that they consumed these beverages to get drunk and reduce sedation compared to alcohol alone. In conclusion, the consumption of AmEDs is common in U.S. college students. Motivations for using AmEDs include the reduction of the sedative effects of alcohol, an important interoceptive cue that one should stop drinking.

A Two-Phase Data Envelopment Analysis Model for Portfolio Selection
David Lengacher,Craig Cammarata
Advances in Decision Sciences , 2012, DOI: 10.1155/2012/869128
Abstract: When organizations do not have well defined goals and constraints, traditional mixed integer programming (MIP) models are ineffective for portfolio selection. In such cases, some organizations revert to building project portfolios based on data envelopment analysis (DEA) relative efficiency scores. However, implementing the most efficient projects until resources are expended will not always result in the most efficient portfolio. This is because relative efficiency scores are not additive. Instead, the efficiency of each candidate portfolio must be evaluated against all possible portfolios, making for a computationally intensive task. This paper has two main contributions to the literature. First, we introduce a new DEA-MIP model which can identify the most efficient portfolio capable of meeting organizational goals at incremental resource levels. Second, by utilizing a second-stage DEA model to calculate the relative effectiveness of each most efficient portfolio, we provide managers, a tool for justifying budget increases or defending existing budget levels. 1. Introduction A critical aspect of management is the decision whereby the best set of projects, or investments, is selected from many competing proposals. In many cases the stakes are high because selecting projects is a significant resource allocation decision that can materially affect the operational competitive advantage of a business [1]. What makes project selection challenging is that the valuation process is oftentimes plagued with high degrees of uncertainty due to long payback periods and changing business conditions. As a result, many researchers have used data envelopment analysis (DEA) as a method by which to evaluate large sets of competing projects [2–6]. DEA was initially developed by Charnes, Cooper, and Rhodes [7] as an efficiency analysis tool and quickly became a popular area in operations research. DEA measures the relative efficiency of decision making units (DMUs) which can represent projects, processes, policies, or organizations. Although all DMUs must be defined in terms of a common set of inputs and outputs, they do not need to have the same units of measurement. DEA scores efficiency on a scale from 0 to 1 and is thus capable of discriminating among the inefficient units, allowing one to rank projects from most to least efficient. Although project efficiency scores provide an appropriate basis on which to compare individual projects, the scores cannot necessary be used to assemble most efficient portfolios. The reason behind this is clear. When two or more projects
