Effect of localized oil spills on Atlantic loggerhead population dynamics  [PDF]
Margaret-Rose Leung, Melissa Marchand, Samantha Stykel, My Huynh, José D. Flores
Open Journal of Ecology (OJE) , 2012, DOI: 10.4236/oje.2012.23013
Abstract: The purpose of this study is to analyze the population dynamics of loggerhead sea turtles (Caretta caretta) affected by localized oil spills. Methods include development of a spatial, stage-classified matrix model parameterized for the following primary loggerhead populations: Gulf of Mexico, western North Atlantic Ocean, and Florida peninsula. Oil spills are simulated deterministically in each population's nesting region, with 1) oil-induced mortality ranging from 25% to 100% and 2) stage classes affected either proportionally or equally. A transient sensitivity analysis was performed to determine the parameters most influential to the population growth rate. Results suggest that increased protection and understanding of young sea turtles found in the Sargasso Sea is essential to the survival of the species. In addition, findings provide insights into the population dynamics of the At- lantic loggerhead turtles and identify conservation measures appropriate in each oil spill case.
CASE STUDY ON THE IMPLEMENTATION OF A VIDEO STORY-BASED INTERVENTI-ON WITH SELF-MODELING TREATMENT PACKAGE TO REDUCE STEREOTYPICAL SPITTING BEHAVIOR IN A YOUNG GIRL WITH AUTISM
Cindy NELSON-HEAD,Doris ADAMS HILL,Margaret FLORES
Journal of Special Education and Rehabilitation , 2012,
Abstract: The purpose of this study was to investigate the use of a video story-based intervention with self-modeling to decrease spitting behavior in a female pre-school student with autism during an extended school year ser-vices program. An A-B-A-B design was used to demonstrate a functional relation between a video story-based intervention with self-modeling and decreased spitting be-havior. The results showed that spitting behavior de-crea-sed as a result of the video-based in-ter-vention package. The implications of these re-sults will be explored.
Workplace mistreatment: Health, working environment and social and economic factors  [PDF]
Margaret Hodgins
Health (Health) , 2014, DOI: 10.4236/health.2014.65057
Abstract:

Objective: To explore patterns of workplace mistreatment, relationships with health and with selected workplace, economic and social factors in 34 countries. Methods: Secondary data analysis of the European Working Conditions Survey. Results: Patterns of ill treatment (across occupational groups, and sectors) were broadly consistent with smaller, less representative studies. Prevalence was lower than many studies but corresponds with estimates of serious mistreatment. Mistreatment increases the risk of both physical and mental ill health and is associated with a range of work environment factors. Mistreatment is more prevalent in countries with smaller gender gaps, better performance on the GINI index for income inequality and for countries with specific anti-bullying legislation. Conclusions: Mistreatment in work is complex, and interventions are required at the level of the organization. Implementation issues need to be addressed, as specific anti-bullying legislation does not appear to provide sufficient protection.

Genetics of a sex-linked recessive red eye color mutant of the tarnished plant bug, Lygus lineolaris  [PDF]
Margaret Louise Allen
Open Journal of Animal Sciences (OJAS) , 2013, DOI: 10.4236/ojas.2013.32A001
Abstract: An inbred colony of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Miridae: Hemiptera), was observed to contain specimens with abnormal traits including red eyes, deformed antennae, and deformed legs. These specimens were isolated and back crossed to create stable phenotypic strains. The only successful strain established was a red eyed strain named Cardinal. The trait was more prevalent and stable in males, suggesting that it could be sex linked. To test the hypothesis that the trait was based on a recessive sex linked allele, classical genetic crosses were performed. The hypothesis was confirmed, and the eye color phenotype was measured and characterized using color analysis software. The trait is similar to other red eyed phenotypes described in this species, but is clearly based on a different mutation since it is sex linked rather than autosomal. The results of crossing experiments also suggest that inbreeding in this species results in substantial fitness cost to laboratory insects.
Stroke and Constipation
—Coincidence or Interrelated?
 [PDF]

Jayaprada Kasaraneni, Margaret Hayes
Health (Health) , 2014, DOI: 10.4236/health.2014.619313
Abstract: Emile Gautier once said, “Freedom of the bowels is the most precious, perhaps even the most essential, of all freedoms—one without which little can be accomplished.” This paper will explore the neuronal physiology, pathophysiology, theories regarding the correlation between stroke and constipation along with a few treatment options. Patients often recovering from stroke complain of constipation and it is most likely attributed to changes in diet, ambulation, or fluid balance. However, there are not many studies to reflect the correlation between other less significant symptoms and stroke presentation.

The Impact of Encroachment on the Distribution of Tree Species in Cross River National Park, Oban Division, Nigeria  [PDF]
Margaret A. Yaro
Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.67068
Abstract: Increasing human activities around protected area pinpoint to looming degradation and alteration of the component of such areas, especially where adequate measures are not taken to forestall encroachment. The Oban division of the Cross River National Park is one of the oldest rainforests and has been identified as a biodiversity hotspot. However, communities settling around the park have been involved in some economic activities for their livelihood. Resource utilization at the edge of the park may alter the components of the park such as species diversity. Therefore this study is geared towards assessing the impact of human encroachment and the concomitant impact on the distribution of species within the park. The study adopted participatory research methods which included Focus Group Discussion and participatory mapping as well as a plot based survey which involved the laying of sample plots within two zones of the park designated as areas bounded by cultivated land and areas bounded by fallow. Three 40 m × 40 m square plots are laid along a 320 meter transect measured from the boundary of the park at each buffer zone. The plots are separated by 100 m gap. From the result obtained, it is discovered that Musanga cercropoides dominates the outer plots of the cultivated zones and fallow zones comprising 20.2 and 21.5 percent respectively while Terminalia ivorensis dominates the middle and inner areas of the park. Moreover the composition of species decreases inward to the inner part of the park. Diversity index decreases in the order of 2.566 < 2.348 < 2.163 at the cultivated zones and 2.443 < 2.376 < 2.366 at the fallow zones. It is concluded that human activities close to the park alters the species composition of the park. Hence, it’s recommended that adequate alternatives livelihood and incentive be provided to support zone communities to reduce their dependents on the edge of the park.
Gold: A Unique Pigmentation Defective Laboratory Strain of the Lady Beetle  [PDF]
Margaret Louise Allen
Advances in Entomology (AE) , 2016, DOI: 10.4236/ae.2016.41002
Abstract: A laboratory colony of Coleomegilla maculata (De Geer) was selected for a novel phenotypic color trait. The phenotype was paler in color than the wild type, although not as pale as a previously described mutant strain, yellow (ye), and retained dark pigmentation in the eyes. This selected strain was named gold. Mendelian breeding experiments indicate a recessive biallelic inheritance. The strain has decreased fitness characteristics based on measurements of egg production and pupa size.
