Does foreign portfolio investment reach small listed firms ?

Using a unique dataset, the author examines the impact of foreign portfolio investment on the capital issuance behavior of small listed firms. The author finds that foreign portfolio investment is associated with an increased probability of small firm security issuance in all nations, regardless of property rights development. Evidence suggests the mechanism by which this occurs is a freeing up of capital in domestic markets when large firms utilize the foreign investment directly. Debt levels in nations where property rights are more developed increase, suggesting that foreign portfolio investment may reach small firms through the banking channel as well as capital markets in these nations.Debt Markets,Access to Finance,Economic Theory&Research,Emerging Markets,Investment and Investment Climate

Facile Synthesis, Characterization, and Antimicrobial Activity of Cellulose-Chitosan-Hydroxyapatite Composite Material: A Potential Material for Bone Tissue Engineering

Hydroxyapatite (HAp) is often used as a bone-implant material because it is biocompatible and osteoconductive. However, HAp possesses poor rheological properties and it is inactive against disease-causing microbes. To improve these properties, we developed a green method to synthesize multifunctional composites containing: (1) cellulose (CEL) to impart mechanical strength; (2) chitosan (CS) to induce antibacterial activity thereby maintaining a microbe-free wound site; and (3) HAp. In this method, CS and CEL were co-dissolved in an ionic liquid (IL) and then regenerated from water. HAp was subsequently formed in situ by alternately soaking [CEL+CS] composites in aqueous solutions of CaCl2 and Na2HPO4. At least 88% of IL used was recovered for reuse by distilling the aqueous washings of [CEL+CS]. The composites were characterized using FTIR, XRD, and SEM. These composites retained the desirable properties of their constituents. For example, the tensile strength of the composites was enhanced 1.9 times by increasing CEL loading from 20% to 80%. Incorporating CS in the composites resulted in composites which inhibited the growth of both Gram positive (MRSA, S. aureus and VRE) and Gram negative (E. coli and P. aeruginosa) bacteria. These findings highlight the potential use of [CEL+CS+HAp] composites as scaffolds in bone tissue engineering

Fraud Detection Protocol for Web-Based Research Among Men Who Have Sex With Men: Development and Descriptive Evaluation

Background: Internet is becoming an increasingly common tool for survey research, particularly among “hidden” or vulnerable populations, such as men who have sex with men (MSM). Web-based research has many advantages for participants and researchers, but fraud can present a significant threat to data integrity. Objective: The purpose of this analysis was to evaluate fraud detection strategies in a Web-based survey of young MSM and describe new protocols to improve fraud detection in Web-based survey research. Methods: This study involved a cross-sectional Web-based survey that examined individual- and network-level risk factors for HIV transmission and substance use among young MSM residing in 15 counties in Central Kentucky. Each survey entry, which was at least 50% complete, was evaluated by the study staff for fraud using an algorithm involving 8 criteria based on a combination of geolocation data, survey data, and personal information. Entries were classified as fraudulent, potentially fraudulent, or valid. Descriptive analyses were performed to describe each fraud detection criterion among entries. Results: Of the 414 survey entries, the final categorization resulted in 119 (28.7%) entries identified as fraud, 42 (10.1%) as potential fraud, and 253 (61.1%) as valid. Geolocation outside of the study area (164/414, 39.6%) was the most frequently violated criterion. However, 33.3% (82/246) of the entries that had ineligible geolocations belonged to participants who were in eligible locations (as verified by their request to mail payment to an address within the study area or participation at a local event). The second most frequently violated criterion was an invalid phone number (94/414, 22.7%), followed by mismatching names within an entry (43/414, 10.4%) and unusual email addresses (37/414, 8.9%). Less than 5% (18/414) of the entries had some combination of personal information items matching that of a previous entry. Conclusions: This study suggests that researchers conducting Web-based surveys of MSM should be vigilant about the potential for fraud. Researchers should have a fraud detection algorithm in place prior to data collection and should not rely on the Internet Protocol (IP) address or geolocation alone, but should rather use a combination of indicators

Protected species aerial survey data collection and analysis in waters underlying the R-5306A airspace: final report submitted to US Marine Corps, MCAS Cherry Point

To be in compliance with the Endangered Species Act and the Marine Mammal Protection Act, the United States Department of the Navy is required to assess the potential environmental impacts of conducting at-sea training operations on sea turtles and marine mammals. Limited recent and area-specific density data of sea turtles and dolphins exist for many of the Navy’s operations areas (OPAREAs), including the Marine Corps Air Station (MCAS) Cherry Point OPAREA, which encompasses portions of Core and Pamlico Sounds, North Carolina. Aerial surveys were conducted to document the seasonal distribution and estimated density of sea turtles and dolphins within Core Sound and portions of Pamlico Sound, and coastal waters extending one mile offshore. Sea Surface Temperature (SST) data for each survey were extracted from 1.4 km/pixel resolution Advanced Very High Resolution Radiometer remote images. A total of 92 turtles and 1,625 dolphins were sighted during 41 aerial surveys, conducted from July 2004 to April 2006. In the spring (March – May; 7.9°C to 21.7°C mean SST), the majority of turtles sighted were along the coast, mainly from the northern Core Banks northward to Cape Hatteras. By the summer (June – Aug.; 25.2°C to 30.8°C mean SST), turtles were fairly evenly dispersed along the entire survey range of the coast and Pamlico Sound, with only a few sightings in Core Sound. In the autumn (Sept. – Nov.; 9.6°C to 29.6°C mean SST), the majority of turtles sighted were along the coast and in eastern Pamlico Sound; however, fewer turtles were observed along the coast than in the summer. No turtles were seen during the winter surveys (Dec. – Feb.; 7.6°C to 11.2°C mean SST). The estimated mean surface density of turtles was highest along the coast in the summer of 2005 (0.615 turtles/km², SE = 0.220). In Core and Pamlico Sounds the highest mean surface density occurred during the autumn of 2005 (0.016 turtles/km², SE = 0.009). The mean seasonal abundance estimates were always highest in the coastal region, except in the winter when turtles were not sighted in either region. For Pamlico Sound, surface densities were always greater in the eastern than western section. The range of mean temperatures at which turtles were sighted was 9.68°C to 30.82°C. The majority of turtles sighted were within water ≥ 11°C. Dolphins were observed within estuarine waters and along the coast year-round; however, there were some general seasonal movements. In particular, during the summer sightings decreased along the coast and dolphins were distributed throughout Core and Pamlico Sounds, while in the winter the majority of dolphins were located along the coast and in southeastern Pamlico Sound. Although relative numbers changed seasonally between these areas, the estimated mean surface density of dolphins was highest along the coast in the spring of 2006 (9.564 dolphins/km², SE = 5.571). In Core and Pamlico Sounds the highest mean surface density occurred during the autumn of 2004 (0.192 dolphins/km², SE = 0.066). The estimated mean surface density of dolphins was lowest along the coast in the summer of 2004 (0.461 dolphins/km², SE = 0.294). The estimated mean surface density of dolphins was lowest in Core and Pamlico Sounds in the summer of 2005 (0.024 dolphins/km², SE = 0.011). In Pamlico Sound, estimated surface densities were greater in the eastern section except in the autumn. Dolphins were sighted throughout the entire range of mean SST (7.60°C to 30.82°C), with a tendency towards fewer dolphins sighted as water temperatures increased. Based on the findings of this study, sea turtles are most likely to be encountered within the OPAREAs when SST is ≥ 11°C. Since sea turtle distributions are generally limited by water temperature, knowing the SST of a given area is a useful predictor of sea turtle presence. Since dolphins were observed within estuarine waters year-round and throughout the entire range of mean SST’s, they likely could be encountered in the OPAREAs any time of the year. Although our findings indicated the greatest number of dolphins to be present in the winter and the least in the summer, their movements also may be related to other factors such as the availability of prey.

The Impact of Educational Policy on English Learners in a Rural Indiana School Corporation

Indiana English learners (ELs) constitute a rapidly growing portion of the state’s school-aged population, and those classified as limited English proficient are low performers on the state test. The purpose of this embedded mixed methods study was to understand how school personnel respond to accountability mandates, interpret test scores, and make decisions on behalf of ELs. Interviews were conducted with four administrators and three EL teachers from a rural Indiana school corporation (i.e., school district) with one of the state’s largest EL populations. In addition, four years of student test scores from the corporation were analyzed. Findings indicate that in response to accountability mandates, school personnel implemented numerous changes, including working together to collectively analyze student test scores and ending sheltered English instruction in two schools. This study illustrates the importance of examining both student test scores and the experiences of educational professionals to understand the intended and unintended results of educational policies

Can We Do It? : The Feasibility of Youth Restorative Justice Implementation in Worcester

This paper addresses the feasibility of implementing a restorative justice process in the juvenile justice system in Worcester, Massachusetts from a community stakeholder perspective. Strengths, barriers, process, and collective will in Worcester were explored. Findings of this research include that while Worcester has many strengths, the barriers and lack of collective will may interfere with any immediate attempts to implement restorative justice processes within the local juvenile justice system. It concludes that while restorative justice approaches may be feasible in the longer term, current implementation is unlikely

Admission criteria in the selection of graduate degree nurses

The purpose of this descriptive quantitative study was to obtain data about the admission criteria and its rank importance to graduate nursing programs used by all accredited nursing schools. Accredited schools of nursing were either National League for Nursing Accrediting Commission (NLNAC) or Commission on Collegiate Nursing Education (CCNE) accredited, or both. A three-page questionnaire designed by the researcher was mailed to the deans or their designees of these 339 accredited programs. There were a total of202 respondents for a response rate of 59.6% to the questionnaire. Data was collected and analyzed using the SPSS V -11 ® program. The findings of this study were that the following six admission criteria were critical for selection of graduate nurse applicants: grade point average (GPA); Graduate Record Examination (GRE); essay; interview; work history; and references. In addition, the top three in rank of importance with these criteria were GPA, references, and work history. The exception was nurse educator programs which ranked essay versus work history as the third most important criteria to admission. The conclusion of this study is that grades remain the most important criteria in the admission process. Further implications of this study include the potential to develop correlational studies based upon various graduate nurse programs and specific admission criteria

Advertising in a World Full of Human Trafficking: How Advertising and Human Trafficking Coincide

As a young woman, I have been groomed to worry about the consequences of what I wear, what I say, and how I interact with men. My grandma is constantly sending me emails with new information on sexual assault or kidnapping cases around the area in which I live. I see articles about human trafficking schemes on my news feed almost weekly. As a young woman, I am conditioned to be on guard at all times because the dangers of being abducted or attacked, specifically trafficked, are portrayed to be more likely than they truly are. Why is this? Why are young women, and some young men, so scared of something happening to them? Is it because of the crimes we see in the world on the news throughout the day? Is it because women are afraid they cannot gain justice if they are attacked? Is it because of the manipulative false advertising of human traffickers? So many of these factors contribute to the unforgiving fear many women hold onto for most of their lives
