Tidal creek networks form the primary hydrologic link between estuaries and land-based activities on barrier islands. A possible impact from the excavation of drainage ditch systems on bacterial communities and biological contamination was studied in the water column and sediments of headwater, mid-stream, and mouth sites of the intertidal Oakdale Creek on Sapelo Island, GA. Community analysis was performed using the MiSeq Illumina platform and revealed that dredging was the cause of a significant rise in Proteobacteria, especially γ-proteobacteria. Targeted biological contaminants included fecal indicator bacteria, Enterococcus spp. (Entero-1), pathogens, Shigella spp. (ipaH), and Salmonella spp (invA), virulence associated genes (VG's) of pathogenic E. coli (eaeA, hlyD, stx1, stx2, and set1B), integrons (intI1, intI2), and tetracycline resistance genes (TRGs). Incidence and gene concentrations of Shigella spp., eaeA and set1B, and of TRGs increased 3–20 folds after the onset of dredging, and followed the dredging schedule. Principal Component Analysis suggested possible common carriers for Shigella spp., some TRGs, and the pathogenic E. coli eaeA gene. At the site of dredging, all of the above contaminants were detected at high concentrations. We concluded that excavation of roadside ditches caused significant changes in bacterial composition and a rise in incidence and concentrations of biological contaminants in the creek. The authors suggest a different approach for the maintenance of this material be explored. © 2017 Elsevier Ltd

Wetlands Ecology and Management | Year: 2017

Crayfish are important in wetland systems because of their function in soil nutrient turnover. Since many crayfishes are imperiled by anthropogenic activities, it is important to understand factors that are associated with their distribution within and among wetlands. This study investigated the soil and hydrogeological characteristics of a wetland and related them to the spatial distribution of crayfish burrows found within it. The study utilized field-collected soil cores, electrical resistivity, and ground penetrating radar to map subsurface characteristics at Bartram Forest, Baldwin County, Georgia. Wetland delineation was also conducted in the field to establish the wetland boundaries. Both 2D and 3D geophysical profiles were created. Soils samples were analyzed for grain size distribution, porosity, and hydraulic conductivity in the lab. Hydraulic conductivity of the wetland soils was also determined in the field using slug tests. Results show subsurface physical differences between crayfish inhabited zones of the wetland and those that do not have crayfish burrows.The Ambiguous Crayfish, Cambarus striatus was found in soils with a hydraulic conductivity of 0.01–0.4 m/day where soils outside of their colony boundary had a hydraulic conductivity of 0.4–1.2 m/day. Areas where C. striatus were located had a higher porosity (0.36) than areas without crayfish (0.26). Subsurface stratigraphy varied between the areas with and without burrows. C. striatus was found to live in a subsurface with relatively gradual stratigraphical boundaries when compared to surrounding areas. © 2017 Springer Science+Business Media Dordrecht

Arts education has been part of the United States K-12 educational system for over a century. However, recent administrative policy decisions addressed the economic bottom line and the 1983 report, A Nation at Risk, and complied with the No Child Left Behind (NCLB) Act of 2001 (U.S. Department of Education, 2001). These decisions resulted in standardisation of both core curricula and testing, leaving arts programs to function in a diminished capacity, curtailing both individuality and creative thinking. This study unpacks the role of the arts as change agents with the ability to: address current discourse; question ideologies and culture; convey complex problems in artistic form; engage the viewer in aesthetics; provide a perspective not found in regimented thinking; and empower creative problem solvers. This work also highlights the role of eco-art as a medium for addressing complex environmental challenges. The study also empirically examines, through a self-report survey, K-12 arts educators’ perceptions of integrating eco-arts into curricula. Findings revealed respondents’ desire to integrate eco-arts into the arts curricula and identified the most significantly perceived barriers to integration, as well as the role of policy on practicality. The authors also identify the study's limitations and recommend areas for future research. Copyright © The Author(s) 2017

Psychopathy has consistently been associated with antisocial outcomes. The three- and four-factor models have been best fitted to data relating to Korean serious offenders (N = 451), offering construct validity of the Korean Psychopathy Checklist-Revised (PCL-R). However, no study has yet tested the predictive power of the Korean PCL-R to explain two different types of antisocial outcomes: (1) risk of inmates measured by correctional officers during incarceration and (2) recidivism after release. By exploring these two forms of antisociality, here we sought to establish the predictive and construct validities of the Korean version of PCL-R. We found that the deviant lifestyle (Factor 3) performed best for predicting both antisocial forms (risk and recidivism) and that the deficits in interpersonal (Factor 1) and affective (Factor 2) abilities also uniquely predicted one subtype of risk, which suggests the three-factor model is better than the four-factor model in predictions. These findings will be useful for criminal justice experts and practitioners in Korea. © 2017 Informa UK Limited, trading as Taylor & Francis Group

Mindfulness-based strategies have received empirical support for improving coping with stress and reducing alcohol use. The present study presents a moderated mediation model to explain how mindfulness might promote healthier drinking patterns. This model posits that mindfulness reduces perceived stress, leading to less alcohol use, and also weakens the linkage between stress and alcohol use. African American smokers (

Understanding the performance of new-well oil production per rig over time and across oil-producing regions serves as an important indicator of current and future production capabilities. As such, this study examines the degree of persistence in response to shocks in new-well production per rig for the six major US oil-producing regions using modified panel ratio tests. The results indicate the instability of new-well production per rig as the degree of persistence changes over time. For companies engaged in the exploration and production of oil, the results highlight the price-taking nature of the industry that is heavily dependent on both physical and financial capital to expand and operate. © 2016 Taylor & Francis Group, LLC.

Moral enhancement can be an attractive proposal, but contrary to cognitive enhancement, it is hard to define what kind of intervention would constitute moral enhancement. In an ongoing debate about the subject, Douglas argued that biomedically decreasing countermoral emotions would do so and would be morally permissible in particular cases. Harris disagreed, and one of his arguments is that failing to address the intellectual aspects of moral decisions-and simply targeting countermoral emotions-would effectively undermine our freedom by reducing our options to act immorally. In a consequent paper, Douglas defended his position. In this paper, I examine Douglas' response to Harris concern about the loss of freedom with biomedical moral enhancement. I argue that Douglas' framework for moral reasoning on which he bases his argument that biomedical intervention is in some cases permissible lacks soundness, and that it apparently undermines morality. Harris insists that morality requires freedom of choice, yet Douglas and Harris have different conceptions of freedom of choice. Douglas' focus on quantity in his defence does not engage with Harris focus on quality of choice. Thus, the kind of biomedical enhancement that Douglas defends is not moral-nor immoral-but amoral enhancement. © 2016 by the BMJ Publishing Group Ltd & Institute of Medical Ethics.

The Princeton chert is one of the most completely studied permineralized floras of the Paleogene. Remains of over 30 plant taxa have been described in detail, along with a diverse assemblage of fungi that document a variety of ecological interactions with plants. As a flora of the Okanagan Highlands, the Princeton chert plants are an assemblage of higher elevation taxa of the latest early to earliest middle Eocene, with some components similar to those in the related compression floras. However, like the well-known floras of Clarno, Appian Way, the London Clay, and Messel, the Princeton chert provides an additional dimension of internal structure. In the present study, we outline the history of Princeton chert plant research, starting with Boneham and others, and extending into studies by Stockey and her students and colleagues. These studies were undertaken primarily at the University of Alberta, Edmonton. We then re-examine the individual elements of the Princeton chert flora, using the framework of the currently recognized Angiosperm Phylogeny Group (APG III) phylogeny and in light of recent fossil discoveries. We hope that this update will bring to mind new aspects of the significance of the Princeton chert flora to Paleogene paleobiology, biogeography, and plant evolution. © 2016, Canadian Science Publishing.

College years are a time young adults examine high-risk sexual behaviors, increasing their risk for sexually transmitted diseases (STDs). Fraternity/sorority membership has been identified as one factor contributing to increased risky sexual behavior in college students. This study measured the effectiveness of an educational intervention targeting STD prevention in fraternity and sorority members, and examined relationships between STD knowledge, attitudes, and demographics.A descriptive, correlational design was used. Pre- and posttest data were collected from fraternity and sorority members (N = 132). Instruments measured demographic characteristics, STD knowledge, and attitudes toward safe sex behaviors.There was a significant increase in STD knowledge from baseline (M = 13.03, SD = 6.5) to 1 week (M = 20.27, SD = 4.9) t (131) = -13.53, p = .000. Males were more likely to report attitudes toward risky sexual behavior rs(132) = .323, p = .000, and as knowledge increased, attitudes became more favorable to safe sex behaviors (pre-STD knowledge and preintervention attitudes, r(132) = -.249, p = .004; post-STD knowledge and postintervention attitudes, rs(132) = -.307, p = .000).Results support that brief STD educational interventions can increase STD knowledge. College health centers must aim to provide sexual health education to all students at every visit.

Pubic hair grooming and removal are common behaviors among men and women. However, little is known about the reasons for grooming, preferred pubic hairstyle of sexual partners, and symptoms associated with regular grooming.This study aims to assess pubic hair removal/grooming practices, pubic hairstyle preferences, and genital outcomes associated with pubic hair removal among men and women in a college sample.Data were gathered from 1,110 participants (671 women and 439 men) at a large public Midwestern university and a small Southern public university.Items assessed demographics, pubic hair grooming and removal practices in the past 4 weeks, reasons for pubic hair status, preference for pubic hairstyle of sexual partners, and symptoms associated with removal and grooming.Most (95%) participants had removed their pubic hair on at least one occasion in the past 4 weeks with shaving being the most commonly reported hair removal technique by women (82%) and men (49%). Women were significantly more likely to report their typical status as hair-free (50% vs. 19%; (2)=165.528, P<0.001) and men were significantly more likely to prefer a hair-free sexual partner (60% vs. 24%; (2)=211.712, P<0.001). Genital itching was experienced on at least one occasion by 80.3% of pubic hair groomers and was the most commonly reported side effect.Genital grooming and pubic hair removal are common practices among both men and women of college-age. Women are likely to report stronger associations with feelings of cleanliness, comfort, sex appeal, social norms of their peer group, and affordability as reasons for their chosen pubic hair style. Women also report more experiences with genital side effects of pubic hair removal, an expected result as women are removing pubic hair more frequently and more completely than their male counterparts.
