    Abstract The employers in our country are claiming students are graduating high school and college without the soft skills to succeed in this country’s workforce. This study examined what are soft skills and why are they missing from recent graduates. The study took an historical approach to trace how soft skills have been used and ignored in our nation’s educational history to the point where employers are claiming they are missing in today’s job applicants. The study then conducted focus groups with elementary, middle and high school teachers to assess they ideas on why soft skills are missing or if they believe these skills are missing at all. The study also contacted employers in the Western Kentucky area to assess do they agree with their national colleagues on whether soft skills are missing, who is to blame for them missing and what can be done to correct this problem. The results were transcribed and coded to recognize the main themes of these two groups. The results, analysis and recommendations were presented to the client, McCracken County Schools. This researcher will work with this school district to use these results to establish what can be done to improve soft skills in their graduates

    The Quest for an AIDS Vaccine

    More than fifty thousand cases of AIDS have been reported in the United States since the disease wasfirst described in 1981. Many times this number of people are infected with human immunodeficiency virus (HIV), which has been identified as the agent responsible for the illness. The seriousness of the disease, coupled with the relatively rapid spread of HIV, has fueled the effort for development of an effective vaccine. Much is now known about the life cycle of the virus, and about its structural components. This information, and information about methods of transmission of the virus, form the basis for a rational vaccine development program. A successful program depends both on technological advances and on the political will to create a climate in which interpretable vaccine trials can be undertaken. This review will focus on some of the impediments to rapid development and licensure of an AIDS vaccine

    Response of lizard community structure to desert grassland restoration mediated by a keystone rodent

    Many grasslands in the Chihuahuan Desert have transformed to shrublands dominated by creosotebush (Larrea tridentata). Grassland restoration efforts have been directed at controlling creosotebush by applying herbicide over large spatial scales. However, we have a limited understanding of how landscape-scale restoration affects biodiversity. We examined whether restoration treatments in southern New Mexico, USA have influenced the community structure of lizards, which are sensitive to shrub encroachment. We compared lizard community structure on 21 areas treated with herbicide from 7 to 29years ago with paired untreated areas that were dominated by shrubs and matched by geomorphology, soils, and elevation. To examine mechanisms underlying responses to restoration, we tested whether the abundance of a grassland specialist, Aspidoscelis uniparens, depended on time since treatment, treatment area and isolation, and local habitat quality. Because lizards use rodent burrows as habitat, we tested whether community structure and A. uniparens abundance depended on the abundance of the keystone rodent, Dipodomys spectabilis. Treated areas had reduced shrub cover and increased grass cover compared to untreated areas. Lizard community composition differed strongly between areas, with four species responding to treatments. Divergence in community composition between treated-untreated pairs was greatest for old treatments (≥22years), and community composition was influenced by D. spectabilis. In particular, the abundance of A. uniparens was greatest on old treatments with a high density of D. spectabilis. Overall, our results demonstrate lizard community structure responds to grassland restoration efforts, and keystone species can shape restoration outcomes. Reestablishment of keystone species may be a critical constraint on the recovery of animal biodiversity after habitat restoratio

    Molecular Detection of Leptospira spp. in Rodents Trapped in the Mozambique Island City, Nampula Province, Mozambique

    Introduction: Leptospirosis is a neglected zoonotic disease caused by a bacteria of the genus Leptospira. In Africa, it is frequently mistaken for frequently occurring conditions such as malaria. The aim of this study was to identify rodent species involved in the transmission of the disease, the prevalence of pathogenic Leptospira spp. in selected rodent species and risk factors for human leptospirosis. Material and Methods: We conducted a descriptive and exploratory epidemiological and molecular study in Mozambique Island city in 2015. Six neighborhoods, comprising 30 households each were randomly selected. People from the selected 180 households were interviewed regarding their awareness of the disease, the presence of rodents in their houses, chemicals used to eliminate them, sewage disposal, water supply system, and other key issues related to the disease. In each neighborhood, we trapped 10 rodents for a morphometric study to identify their species and for molecular isolation of Leptospira DNA. We extracted kidneys from 57/60 of rodents trapped and performed nested polymerase chain reaction targeting rrs 16S ribosomal RNA and lipL32 genes for identification of Leptospira genus and pathogenic Leptospira spp. respectively. Results: Of the 180 participants 92 (51%) reported having heard of leptospirosis;107 (59%) have had the disease; 151 (83%) reported the existence of rats in their house; 100 (56%) had latrines; 118 (66%) used chemicals to kill the rats; 102 (57%) used well water and 114 (63%) used trash containers. The most prevalent rodent species captured was Rattus norvegicus 36/60 (60%), followed by Rattus rattus 19/60 (31.67%) and Mus musculus 3/60 (5%). Sequences of rrs 16S rRNA gene were identified rrs 16S ribosomal DNA RNA was identified in 20/57 (35.%) rodents. Out these two were positive for lipL32 gene, giving an overall pathogenic Leptospira infection of 3.5% (2/57). The rodent species identified as carriers of pathogenic Leptospira were Rattus norvegicus (1) and R. rattus (1). Conclusion: This is the first study in Mozambique to identify the presence of pathogenic species of Leptospira using molecular tools. Leptospirosis risk factors in Mozambique Island city are rodent’s infestation, limited disease awareness, lack of access to clean water, insufficient resources for waste collection, greater clustering of households, poor sanitation environment and degradation of living conditions. Pathogenic Leptospira spp. are present in the area studied and at least two species of rodents, the R. rattus and R. norvegicus are potentially involved in the transmission of the causal agents of the disease.publishersversionpublishe

    Wetland Occupancy and Landscape Connectivity for Blanding’s and Western Painted Turtles in the Green River Valley

    We surveyed all wetlands in a 9277-ha area in Lee County, IL with the intention to use occupancy and least-cost modeling to assess how landscape structure affects the distribution and population connectivity of Emydoidea blandingii (state-threatened Blanding’s Turtle) and the locally common Chrysemys picta (Western Painted Turtle). Both species are members of the Family Emydidae. Originally dominated by open marshes and sand prairie, the Green River valley in Lee County is now characterized by agricultural fields, roads, and fragmented patches of natural habitat. Surveys by the Lee County Natural Area Guardians and Illinois Natural History Survey (INHS) personnel resulted in E. blandingii captures in this area as recent as 2006. However, the current extent and status of this population was unknown. This research was conducted to (1) identify important habitat features affecting the occupancy and connectivity of the threatened Blanding’s turtle and common Painted Turtle in and around managed sand prairie habitat, and (2) assess how occupancy and connectivity patterns vary for a species of conservation concern and a closely related, abundant species in the same landscape.unpublishednot peer reviewedOpe
