Accelerated Share Repurchases

Accelerated share repurchases (ASRs) are credible commitments by firms to repurchase shares immediately. Including an ASR in a repurchase program reduces the flexibility that firms have to alter an announced program in response to subsequent changes in the price and liquidity of its shares, unexpected shocks to cash flow and/or investment, etc. Thus, we investigate whether firms’ decisions to include ASRs in their repurchase programs are associated with factors expected to influence the costs of lost flexibility and the benefits of enhanced credibility and immediacy. We find robust evidence consistent with the costs of lost flexibility and the benefits of credibility and immediacy being important determinants of ASR adoption. Additionally, we find that ASR announcements are associated with positive average abnormal stock returns

Two leaf beetles new to Florida (Coleoptera: Chrysomelidae)

Specimens recently submitted to the first author for identification turned out to represent two species of leaf beetles previously unknown from Florida, one of which is new to the eastern United States and the other new to the continental United States

Psychometric properties and factor structure of the computerized PTSD scale -multimedia version among adult samples reporting trauma

This study investigated the psychometric properties of the Computerized PTSD Scale-Multimedia Version (CPS-M: Richard, Mayo, Bohn, Haynes, & lll Kolman, 1997), a self-administered adaptation of the Clinician-Administered PTSD Scale (CAPS: Blake, Weathers, Nagy, Kaloupek, Klauminzer, Charney, & Keane, 1990). The sample included 161 participants from both a veteran\u27s hospital and from a large urban outpatient HMO system who reported a history of trauma. Indices of internal consistency reliability (i.e., inter-item correlations, item-scale correlations, coefficient alpha) and temporal stability fell in satisfactory ranges. To assess convergent and discriminant validity, correlations were calculated between the CPSM and the following instruments: Purdue PTSD Scale, Beck Depression Inventory II (BDI-II), Hospital Anxiety and Depression Scale (HADS), Yale-Brown Obsessive Compulsive Scale (YBOCS), and Antisocial Behavior Inventory (ASBI). As hypothesized, the CMS-M was most strongly correlated with another measure of PTSD (r = .90) followed by the BDI-II (r = .85), HADS (r = .79), YBOCS (r = .71), and ASBI (r = .25). Confirmatory factor analysis procedures were used to assess fit of a set of nested measurement models. The fit of four different measurement models was tested. An oblique four-factor, first order model composed of reexperiencing (Bl-B5), avoidance (Cl-C2), dysphoria (C3-C7 & Dl-D3), and hyperarousal (D4- D5) provided the best fit to the data

Ecological Process and the Blister Rust Epidemic: Cone Production, Cone Predation, and Seed Dispersal in Whitebark Pine (Pinus albicaulis)

Whitebark pine (Pinus albicaulis), a high elevation foundation species, is experiencing population declines throughout the northern part of its range. The introduced fungal pathogen, Cronartium ribicola (white pine blister rust), infects whitebark pine and kills cone-bearing branches and trees. Blister rust has spread nearly rangewide and damage and mortality are highest in the northwest US and southwest Canada. Mortality caused by mountain pine beetle (Dendroctonus ponderosae) population upsurges, and successional replacement and loss of regeneration opportunities from fire suppression, are also impacting some whitebark pine populations. Within this dissertation, I present three manuscripts that address the impact of whitebark pine\u27s decline on species interactions and ecological processes within subalpine forests. Research was conducted in three ecosystems in the Rocky Mountains USA that are distinct in whitebark pine health conditions (rust infection and mortality) and abundance. In the first manuscript, I explore how the relationship between whitebark pine and Clark\u27s Nutcracker (Nucifraga columbiana), its primary seed disperser, is being affected by whitebark\u27s decline. Nutcrackers were less likely to use and disperse seeds from forests where cone production is below a threshold. In the second manuscript, I describe habitat use of whitebark pine forests by red squirrels (Tamiasciurus hudsonicus). Squirrel residency and impact of cone predation increased with decreasing whitebark pine abundance. The third manuscript focuses on the tree-level ecological process, predispersal cone survival, as a function of coarse scale whitebark pine abundance. Surviving trees in high mortality forests were found to have a lower rate and higher variability of cone survival, suggesting that the putative levels of rust-resistance in surviving trees of high mortality forests may not be passed on to future generations. At the ecosystem level, the Northern Divide had the highest levels of rust infection and tree mortality and lowest nutcracker interaction and regeneration levels; the Greater Yellowstone had the lowest infection and mortality levels and nutcrackers were present and dispersing seeds at all research sites in all years, while the Bitterroot Mountains were intermediate in these comparisons. These findings provide important components for developing a long-term strategy to conserve and restore whitebark pine ecosystems in the Rocky Mountains

Strategies and Internal Control Procedures for Decreasing Fraud in Faith-Based Nonprofit Organizations

This study addressed the problem regarding the lack of strategies and internal controls in faith-based nonprofit organizations which resulted in a higher risk of fraud, waste of funds, or abuse of funds in charities, churches, and other related ministries. This risk was the result of trust by organizations that employees would not commit fraud and due to a lack of sufficient resources. This study specifically researched faith-based nonprofit organizations that are located in Texas. This qualitative case study included two faith-based nonprofit organizations located in or near Houston, Texas. The research found several themes including: frauds occur, segregation of duties, approval controls, review process, and policies and procedures. The study also found several internal controls, policies, and procedures that these organizations could implement to decrease the risk of fraud, such as a whistleblower policy, background checks, segregation of duties, review of financials, and limited access to accounting procedures. Further research could be conducted on the implementation of internal controls after a fraud was discovered and the restoration of donor trust

Individual Differences in Perceptions of Health-Related Behaviors

When provided an opportunity for thought, individuals experience a strengthening of their already moderate attitude toward some attitude object. This process was studied in the context of variables – attitudes toward behavior, norms about behavior, and perceived behavioral control – known to predict intentions to engage in health-related behavior. A potential moderator of this process – locus of control beliefs – was also investigated. In this study, 195 participants indicated their attitudes toward eight health-related behaviors. Participants were randomly assigned to either a high or low opportunity for thought during which time they were asked to focus their thoughts on the health behavior getting 8 hours of sleep a night. Participants then responded to 18 items measuring Theory of Planned Behavior constructs and the 18-item Multidimensional Health Locus of Control scale. Although self-generated attitude polarization was not observed in this study, evidence was found which supports previous Theory of Planned Behavior and Multidimensional Health Locus of Control research findings. Study limitations and implications are discussed. Keywords: attitudes, attitude change, health locus of control, theory of planned behavio

Cardio-Protection Afforded by Β-Blockade Is Maintained During Resistance Exercise

Objectives Whether or not the cardio-protective effect of β-adrenergic blockade is retained during resistance exercise has not been systematically evaluated. Therefore the purpose of this study was to measure selected cardiorespiratory responses to isometric exercise involving hand-gripping, single-leg extension, or double-leg dead-lift, under placebo (control), β1-selective (atenolol), and non-selective (propranolol) adrenergic blockade conditions. Design Eleven young male adults were evaluated in a randomized, double-blinded, repeated measures study design and performed all three exercise modalities at 30% of maximal voluntary contraction under placebo, atenolol and propranolol conditions. Methods Heart rate, systolic and diastolic blood pressure, rate-pressure product, oxygen uptake, cardiac output, stroke volume and total peripheral resistance were directly measured or calculated at rest and during the third minute of each of the three exercise modes. Results Irrespective of drug condition, a graded pressor response was observed going from rest to exercise so that rest \u3c handgrip \u3c leg extension \u3c dead-lift for heart rate, systolic and diastolic blood pressures, rate-pressure product and oxygen uptake (p \u3c 0.05 for all). Cardiac output only increased with the dead-lift mode of exercise (p \u3c 0.01). Importantly β-adrenergic blockade with either atenolol or propranolol similarly attenuated the rise in heart rate, and systolic blood pressure; thus rate-pressure product demonstrated a mode-of-exercise by drug interaction effect (p \u3c 0.001) with the greatest reductions seen with the dead-lift procedure. Conclusions The findings indicate that cardio-protection afforded by selective or non-selective β-blockade at rest is preserved during isometric exercise and even enhanced once heart rate increases above 100 beats min−1

Psoriasis Vulgaris Successfully Treated with Goeckerman Treatment at Home: A Patient and Physician's Experience.

Goeckerman therapy is a highly effective treatment regimen for moderate-to-severe psoriasis. It involves regular exposure to ultraviolet B radiation and the application of crude coal tar. To our knowledge, only three centers in the USA currently offer a formal Goeckerman therapy treatment program; thus, access to this therapy is geographically limited. In this article, a motivated patient discusses his experience with generalized plaque psoriasis. This patient, while living in a Goeckerman-inaccessible area, deferred treatment with biologics and outpatient phototherapy to develop a modified Goeckerman regimen for at-home use. This home regimen, which did not involve the use of prescription-strength medications, resulted in full clearance of his psoriasis. We also discuss the patient's case from the perspective of a dermatology treatment team that has reviewed his experience
