Experiential Learning in Graduate Education: Development, Delivery, and Analysis of an Evidence-Based Intervention  [PDF]
Samantha M. Harden, Kacie C. Allen, Clarice N. Chau, Serena L. Parks, Ashley L. Zanko
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.35095
Abstract: Certain expectations are outlined for a young professional with a recently earned doctoral degree. In academia, it is anticipated that graduates will demonstrate the ability to obtain funding, actively engage in an interdisciplinary work environment, and value experiences with critical thinking and problem solving. This paper outlines a unique learning experience of five graduate research students who progressed from the initial stage of research question conceptualization to dissemination of research results. The process included a written research design proposal, grant review process, physical activity program development, intervention delivery, data analysis, and publication of findings. Challenges overcome by these young investigators throughout the research process (i.e. intervention recruitment, development and delivery) are included within the manuscript, as well as other important findings from this process evaluation. The first-hand account of their learning experiences demonstrates the value of promoting internal competition (i.e., within a department, college, university), while working as a collaborative research team to prepare graduate students for ‘real-world’ research and work-related scenarios. Graduate student faculty mentors should incorporate more opportunities for their students to glean research experience described here.

Abstract: The article deals with one of the main streams in Danish contemporary literature, namely the realistic minimalism. Minimalism appeared in Danish contemporary literature at the beginning of the 1990-ties. It was developed by the first generation of writers, who graduated at that time from The Danish School of Writers (Forfatterskolen), founded in 1987 in Copenhagen by the Danish modernist poet and literary critic Poul Borum. The first graduates from The Danish School of Writers wrote mainly short stories, characterized by economy of words and focus on surface description. Due to their form as well as subject matter the works written by Danish minimalists are often called for snapshots of everyday life in nowadays Denmark. Soon after that great outburst of minimalism in Danish literature from the early 90’ties the critics proclaimed the so-called “return to reality” in Danish contemporary literature. Owing to that remarkable phenomenon minimalist literature composed by Danish contemporary writers is often described as a renewed version of realism, whose roots go back to the 70-ties and the 80-ties of the 19th century. The present article gives a brief characteristics of the main features typical of the Danish minimalist realism, which have been discussed in the light of the first wave of realistic literature that came to Denmark in the second half of 19th century. In this way the author compares two related, but though different literary techniques practised by the two generations of Danish realists: the contemporary on the one hand, among whom the author mentions such names as Christina Hesselholdt, Helle Helle and Solvej Balle, as well as their forefathers on the other, where the author respectively refers to Herman Bang, Jens Peter Jacobsen and Henrik Pontoppidan. On the basis of this comparison the author seeks to point out the similarities and the differences between the two series of literary accounts of the Danish reality with regard to their genre specification, form, language and themes. Finally, the author considers the role of minimalism in the contemporary Danish literature and mentions some possible sources of the great interest that minimalist literature still enjoys in Denmark.
Contraception and Venous Thromboembolism: Risk Factors and Clinical Considerations  [PDF]
Ashley Waddington, Carrie Ferguson, Robert L. Reid
Open Journal of Obstetrics and Gynecology (OJOG) , 2017, DOI: 10.4236/ojog.2017.71003
Abstract: Venous thromboembolism (VTE) is a known risk with some forms of hormonal contraception, and should be considered by health care providers when counselling patients about their contraceptive options. Various other risk factors exist for VTE, including family history of VTE and a personal history of VTE or thrombophilia. This article will summarize various known risk factors for VTE, as well as what is known about the VTE risk imparted by the use of different contraceptives.

Lead poisoning due to geophagia: The consumption of miniature pottery  [PDF]
Ashley Phipps, Heather Fels, Mackenzie S. Burns, Shawn L. Gerstenberger
Open Journal of Pediatrics (OJPed) , 2012, DOI: 10.4236/ojped.2012.21010
Abstract: Geophagia (the pica of pottery, clay, earth, or dirt) is practiced before and during pregnancy in several countries, including Mexico, Turkey, Australia, and some African countries, and has been linked with cultural fertility beliefs and the satisfaction of cravings. Unfortunately, consumption of contaminated pottery can represent a source of lead exposure. Concerns regarding ingested pottery are two-fold; first, that people consuming these pots might be exposed to high concentrations of lead, and, second, that ingestion of these pots by pregnant women could result in elevated in utero lead exposure for the fetus. Very few published articles exist on this topic. In an effort to investigate “pot eating”, this study aims to summarize published case studies on lead poisonings resulting from consumption of contaminated pottery. Additionally, several pottery items that are sold for the purpose of consumption were located and analyzed. This paper investigates the risk that “pot eating” poses by reviewing the literature, examining case studies, and analyzing the availability and lead concentration of edible pottery. Preliminary research indicates that although it is not common, “pot eating” can represent a high-risk lead exposure for pregnant women and their fetuses.
Contrasting Socio-Economic and Demographic Profiles of Two, Small Island, Economic Species: MIRAB versus PROFIT/SITE
Ashley Oberst,Jerome L. McElroy
Island Studies Journal , 2007,
Abstract: The MIRAB model developed by Bertram and Watters, based on remittances and aid, has dominated the small island economy literature for two decades. Recently, two challenges have surfaced: the PROFIT formulation emphasizing domestic policy flexibility - a so-called ‘resourcefulness of jurisdiction’ - and a dynamic private sector (Baldacchino, 2006); and the SITE model, stressing the role of tourism (McElroy, 2006). To date, there has been no comparative assessment of these different island models. This article addresses this gap. Its point of departure is to consider SITE islands as a subspecies of the PROFIT cluster. It constructs comprehensive profiles across 27 socio-economic and demographic variables for two island sub-groups with populations of less than three million: 23 MIRAB and 35 PROFIT-SITE. Results indicate PROFIT-SITE islands are much more affluent, socially advanced and demographically mature than their MIRAB counterparts.
The stability of abstract boundary essential singularities
Michael J. S. L. Ashley
Mathematics , 2002,
Abstract: The abstract boundary has, in recent years, proved a general and flexible way to define the singularities of space-time. In this approach an essential singularity is a non-regular boundary point of an embedding which is accessible by a chosen family of curves within finite parameter distance. Ashley and Scott proved the first theorem relating essential singularities in strongly causal space-times to causal geodesic incompleteness. Linking this with the work of Beem on the $C^{r}$-stability of geodesic incompleteness allows proof of the stability of these singularities. Here I present this result stating the conditions under which essential singularities are $C^{1}$-stable against perturbations of the metric.
Turbo Analog Error Correcting Codes Decodable By Linear Programming
Avi Zanko,Amir Leshem,Ephraim Zehavi
Mathematics , 2009,
Abstract: In this paper we present a new Turbo analog error correcting coding scheme for real valued signals that are corrupted by impulsive noise. This Turbo code improves Donoho's deterministic construction by using a probabilistic approach. More specifically, our construction corrects more errors than the matrices of Donoho by allowing a vanishingly small probability of error (with the increase in block size). The problem of decoding the long block code is decoupled into two sets of parallel Linear Programming problems. This leads to a significant reduction in decoding complexity as compared to one-step Linear Programming decoding.
Network coding for multicasting over Rayleigh fading multi access channels
Avi Zanko,Amir Leshem,Ephraim Zehavi
Computer Science , 2014,
Abstract: This paper examines the problem of rate allocation for multicasting over slow Rayleigh fading channels using network coding. In the proposed model, the network is treated as a collection of Rayleigh fading multiple access channels. In this model, rate allocation scheme that is based solely on the statistics of the channels is presented. The rate allocation scheme is aimed at minimizing the outage probability. An upper bound is presented for the probability of outage in the fading multiple access channel. A suboptimal solution based on this bound is given. A distributed primal-dual gradient algorithm is derived to solve the rate allocation problem.
Targeting viral infection by microRNA inhibition

Abstract: MicroRNAs (miRNAs) are gaining an increasingly prominent role as regulators of numerous cellular processes, including virus-host interactions. They are short (21-23 nucleotide) non-coding regulatory RNAs that influence gene expression at a post-transcriptional level [1]. miRNAs are encoded as part of long nuclear transcripts, which are processed in the nucleus by Drosha, then exported to the cytoplasm and further processed by Dicer. The resulting mature miRNA strand is loaded into the RNA-induced silencing complex (RISC), which acts as the effector of miRNA activity [1]. In animals, target specificity is usually determined by a 6-8mer 'seed' at the 5' end of the miRNA. Typically, miRNAs bind sites in the 3' untranslated regions (UTRs) of mRNAs that have perfect complementarity to the seed but imperfect complementarity to the remainder of the miRNA. The precise mechanism of miRNA-mediated repression is not fully defined; both translational repression and degradation of miRNA-RISC-bound mRNAs have been observed in different studies [1].Several viruses interact with the miRNA pathway. Certain viruses produce their own miRNAs, which regulate viral or cellular targets, whereas some viruses are regulated directly or indirectly by cellular miRNAs [2]. One important virus that has a requirement for a specific miRNA is hepatitis C virus (HCV). HCV infects the liver and is a major global health concern, with an estimated 170 million people infected worldwide [3]. In the majority of cases acute infection with HCV progresses to chronic infection, although infection can be cleared spontaneously in a minority of cases. Chronically infected individuals may then develop cirrhosis of the liver and may ultimately progress to hepatocellular carcinoma. HCV is predominantly spread through direct blood contact, although there is some evidence to suggest a possible (minor) route of sexual transmission [3]. A report recently published in Science [4] shows that inhibiting a specific miRNA i
