Species composition, demographics, and ecosystem services of residential trees in Louisville, Kentucky.

Trees in urban residential neighborhoods provide valuable ecosystem services. Urban trees also face threats from disturbances, such as storms. In 2008, the Urban Forest Effects model was used to estimate abundance and species composition of residential trees and their ecosystem services in 10 of 26 council districts in Louisville, Kentucky. Ten tree species were found to compose half of the estimated 822,576 residential trees in the ten districts, with Celtis occidentalis being most numerous. The ability of sociodemographic and housing variables to predict the distribution of trees and ecosystem services was weak. The strongest relationships were found between % single home and % owner resident and tree number, species richness, and Shannon diversity. After two record-breaking storms in 2008 and 2009, tree canopy losses were found to be 7.9 % with concomitant decreases in ecosystem services. A survey showed only 33% of residents intended to replant lost trees

Characteristics of the Romanian Entrepreneurial Prototype

The objective of this paper is to portray the Romanians’ entrepreneurial current prototype, following to their cultural background and entrepreneurial education – as result of the authors’ own research, and compared to previous similar studies. The research methodology includes both secondary and primary research. The landscape of the entrepreneurial activity in Romania is centred on the profile of the Romanian entrepreneur as offered by “The Global Entrepreneurship Monitor”. The results of two studies completed in Romania, based on Hofstede’s model of cultural dimensions, are analyzed too. As primary research, the paper presents the results of the authors’ investigations around two focus groups which were conducted in Romania. Consequently, the Romanian Entrepreneurial Prototype was developed (2008-2009). In this context, the importance of entrepreneurial higher education is highlighted as well. The research results are important for entrepreneurs and business consultants as well as for strategists and education policy makers – aiming at developing entrepreneurship.cultural dimensions; entrepreneurship; entrepreneurial prototype; entrepreneurial profile; entrepreneurial education; Romanian entrepreneurs.

Employee Tenure Moderates the Effect of HRM Practices and Fit on Retention

Person-Organization (P-O) and Person-Job (P-J) fit are critical in retaining talent. Research has focused on the earliest time in an employee’s life with the company. The current research expanded this scope, to explore the role of fit perceptions and the HRM practices driving them, as moderated by employee tenure. The moderating effect of employee tenure on the relationships between HRM practices, fit perceptions, and retention related attitudes was examined. Results indicate tenure moderates the effects, such that for employees of very low or high tenure, P-O fit yields stronger predictive relationships with retention, whereas for employees of moderate tenure, P-J fit yields stronger predictive relationships

Elevated Chemokine C-C motif ligand 2 (CCL2) early in pregnancy is associated with increased risk of preeclampsia in obese parturients

The objective of this study is to measure plasma CCl2 and leptin early in control and obese women and associate pregnancy outcomes with these levels. We hypothesize that early elevations of plasma CCL2 will be predictive of the development of poor pregnancy outcomes

Private Landowners’ Willingness to Enroll Their Properties in a Public Hunting Access Program in Northeast Missouri

State wildlife agencies have successfully used public hunting access fees to increase hunting opportunity and to provide a financial incentive to private landowners for maintaining habitat. Typical payments per hectare (ac) include $3.29 ($1.25) on average in Kansas, $2.47-$3.71($1-$1.50) for pheasant hunting in Colorado, $2.47-$12.36 ($1–$5) in North Dakota for pheasant hunting, and $4.45 ($1.80) on average in South Dakota. We studied the USDA Conservation Reserve Program (CRP) in 2004 in Adair, Knox, Macon, Monroe, Ralls, Randolph, Schuyler, and Scotland counties in northeast Missouri as part of a quail and songbird habitat restoration initiative. CRP is prominent in these counties with 83,040 ha (205,197 ac) enrolled. We conducted a mail-back survey of all CRP contract holders, totaling 3,283 landowners to study their willingness to enroll their properties in a hypothetical public- access hunting program. The survey was designed to provide information about landowner demographics, attitudes toward wildlife and hunting, and knowledge of wildlife habitat management aspects of the CRP. We used the Kansas Department of Wildlife and Parks Walk-In Hunting Access Program as an example for questions related to the concept of public-access hunting, and presented landowners with hypothetical annual lease payments for enrolling, using a discrete-choice modeling framework. Survey response rate was relatively high at 59.5%. The average respondent had 34.6 ha (85.5 ac) enrolled in CRP, and field size averaged 6.47 ha (16.0 ac), ranging from 0.04 to 84.9 ha (0.1–209.7 ac). Wildlife as a product of the CRP was ‘very’ or ‘somewhat important’ to 89% of respondents and, among a list of wildlife species and native plants, northern bobwhite (Colinus virginianus) was most popular with 80% of respondents checking ‘very’ or ‘somewhat important’ on the survey. The corresponding values were 53–66% for wild turkey (Meleagris gallopavo), deer, rabbit, pheasant, and songbirds. We asked if landowners would enroll any of their CRP land in a public-access hunting program (PAHP). We used 8 different versions of the survey, each with a different ‘offer’ level in the question to evaluate the potential costs of a PAHP program. The structure of the survey specified whether landowners would accept payment of $X/ac, where X was one value randomly selected from the set of$1, $2,$3, $4,$5, $7,$10, or $20. None of respondents chose ‘yes’ at a PAHP value of$0, 91.9% chose ‘no’, and 8.1% chose ‘don’t know’; respective values ($) and choices ($1-1.7%, 91.3%, and 6.9%; $2-3.0$3-4.0%, 84.9%, and 11.2%; $4-3.4$5- 4.7%, 83.4%, and 11.9%; $7-7.1$10-8.4%, 77.0%, and 14.7%; and $20-14.8$2/ac ($4.94/ha), ~ 3$10,500. About 1,012 ha (2,500 ac) would be designated for quail hunting of this hypothetical PAHP area, based on respondents’ answers to what type of hunting they would allow. We estimate that 5,261 ha (13,000 ac) would be enrolled with 2,489 ha (6,150 ac) open for quail hunting at an annual cost of about $90,000 if the payment level was raised to$7/ac ($17.30/ha). There is potential to improve the feasibility of CRP lands for bobwhite hunting in northeast Missouri by adding a public-access hunting incentive, but managers will be challenged to use this approach successfully. Landowners’ inclination to allow access for deer hunting, but not for quail hunting, reduces an agency’s justification for using quail hunting access as an approach to improve conservation of bobwhites, in addition to the relatively high cost

Cadherin-26 (CDH26) regulates airway epithelial cell cytoskeletal structure and polarity.

Polarization of the airway epithelial cells (AECs) in the airway lumen is critical to the proper function of the mucociliary escalator and maintenance of lung health, but the cellular requirements for polarization of AECs are poorly understood. Using human AECs and cell lines, we demonstrate that cadherin-26 (CDH26) is abundantly expressed in differentiated AECs, localizes to the cell apices near ciliary membranes, and has functional cadherin domains with homotypic binding. We find a unique and non-redundant role for CDH26, previously uncharacterized in AECs, in regulation of cell-cell contact and cell integrity through maintaining cytoskeletal structures. Overexpression of CDH26 in cells with a fibroblastoid phenotype increases contact inhibition and promotes monolayer formation and cortical actin structures. CDH26 expression is also important for localization of planar cell polarity proteins. Knockdown of CDH26 in AECs results in loss of cortical actin and disruption of CRB3 and other proteins associated with apical polarity. Together, our findings uncover previously unrecognized functions for CDH26 in the maintenance of actin cytoskeleton and apicobasal polarity of AECs

Global fetal DNA methylation and birth outcomes in obese women

Pregnant women who are obese are more likely to have gestational diabetes, gestational hypertension, pre-eclampsia, macrosomia, operative vaginal delivery, and cesarean delivery. Obesity also has adverse implications for the neonate. Congenital anomalies are more common in children born to obese women. These include neural tube defects, gastroschisis, cardiovascular anomalies, and others. Although the connection between maternal obesity and chronic health conditions has been described, the mechanism by which this occurs is less well understood. Changes to the epigenetic structure of offspring DNA have been proposed as one such mechanism

Vasopressin, depression, pain & preeclampsia

Preeclampsia (PreE) is a prevalent hypertensive disorder of pregnancy leading to a death every minute worldwide. Predictive and preventative challenges in PreE stems from its unclear early-pregnancy etiology. Arginine vasopressin (AVP) secretion, as measured by copeptin, activates the stress response system and is a novel, early pregnancy predictor of PreE. In addition, elevated AVP is associated with stress, depression and pain. Our Precision Healthcare goal is to understand how AVP-associated changes in depression and pain affect the phenotype of PreE to develop preventative and therapeutic modalities against it. We hypothesize that in humans, antecedent depression and pain affects early pregnancy AVP secretion/copeptin which will be differentially predictive of PreE. To address this hypothesis we aim to 1) determine the association of maternal plasma copeptin and measures of depression and pain throughout human gestation and 2) determine how depression and pain through gestation affects an early pregnancy copeptin based prediction model of preeclampsia

Effects of biological factors on the expression of arginine vasopressin receptors

Arginine vasopressin (AVP) is a hormone that functions to regulate blood pressure and bodily fluid homeostasis. Vasopressin has three main receptors AVPR1a, AVPR1b, and AVPR2 which were investigated in this project along with OXTR, LNPEP, and CUL5. AVPR1a functions in the smooth muscle and causes vasoconstriction, AVPR1b functions in the pituitary helping to regulate adrenocorticotropic hormone release, and AVPR2 is expressed highly in the kidneys and works to concentrate urine. This project investigates how these various receptors are expressed with different factors related to pregnancy such as, sex of the baby, chronically hypertensive mothers, and gestational age at deliver
