A Descriptive Study on the Preparation of Student Teachers to Work with Diverse Populations

If the agricultural education profession is to attract a more diverse audience to pursue agriculture as a viable career path, the secondary teacher education pathway must be reevaluated. The purpose of the study was to describe the degree to which the involved agricultural education programs prepared their students to work with diverse populations. The study also examined attitudes and beliefs of the student teachers regarding diversity. The results of the study suggest that this group of student teachers was not adequately exposed to diversity neither in their student teaching experience nor in their university preparation. To assist the national agricultural education goal of diversity in agriculture, a national study should be conducted to determine if there is a correlation between minority enrollment in agriculture and the race and gender of the teacher educator

Decreased Serum Hepatocyte Growth Factor (HGF) in Autistic Children with Severe Gastrointestinal Disease

Aim To assess serum Hepatocyte Growth Factor (HGF) levels in autistic children with severe gastrointestinal (GI) disease and to test the hypothesis that there is a relationship between GI pathology and HGF concentration. Subjects and Methods Serum from 29 autistic children with chronic digestive disease (symptoms for a minimum of 6–12 months), most with ileo-colonic lymphoid nodular hyperplasia (LNH—markedly enlarged lymphoid nodules) and inflammation of the colorectum, small bowel and/or stomach), and 31 controls (11 age matched autistic children with no GI disease, 11 age matched non autistic children without GI disease and 9 age matched non autistic children with GI disease) were tested for HGF using ELISAs. HGF concentration of autistic children with GI disease was compared to GI disease severity. Results Autistic children with GI disease had significantly lower serum levels of HGF compared to controls (autistic without GI disease; p = 0.0005, non autistic with no GI disease; p = 0.0001, and non autistic with GI disease; p = 0.001). Collectively, all autistic children had significantly lower HGF levels when compared to non autistic children (p < 0.0001). We did not find any relationship between severity of GI disease and HGF concentration in autistic children with GI disease. Discussion These results suggest an association between HGF serum levels and the presence of GI disease in autistic children and explain a potential functional connection between the Met gene and autism. The concentration of serum HGF may be a useful biomarker for autistic children, especially those with severe GI disease

Identifying the Roles and Challenges of Female Agricultural Teachers Employed in Illinois: A Descriptive Study

In 1980, one of the first female high school agriculture teachers opened the door to her classroom at Arthur High School, Arthur, Illinois. Since that time, the number of female high school agriculture teachers has grown significantly. A descriptive study was conducted to identify and describe the roles and challenges of female high school agricultural teachers employed in Illinois. The results of the study can be used as a preparation tool for those females who decide to pursue agricultural education as a career, and can be used to encourage more female students to enter this challenging career. This study also describes the demographics, background, and support given to female teachers of agriculture in Illinois prior to and after college. Almost half the current female high school agriculture teachers are under the age of 30, and 52% of these teachers are instructors of Agricultural Mechanization, a once male-dominated area of instruction

Space tug propulsion system failure mode, effects and criticality analysis

For purposes of the study, the propulsion system was considered as consisting of the following: (1) main engine system, (2) auxiliary propulsion system, (3) pneumatic system, (4) hydrogen feed, fill, drain and vent system, (5) oxygen feed, fill, drain and vent system, and (6) helium reentry purge system. Each component was critically examined to identify possible failure modes and the subsequent effect on mission success. Each space tug mission consists of three phases: launch to separation from shuttle, separation to redocking, and redocking to landing. The analysis considered the results of failure of a component during each phase of the mission. After the failure modes of each component were tabulated, those components whose failure would result in possible or certain loss of mission or inability to return the Tug to ground were identified as critical components and a criticality number determined for each. The criticality number of a component denotes the number of mission failures in one million missions due to the loss of that component. A total of 68 components were identified as critical with criticality numbers ranging from 1 to 2990

Learning Disabled Student Needs Met Through Curriculum Redesign of the Illinois Agricultural Education Core Curriculum

This quasi–experimental pilot study included agricultural education students with Specific Learning Disabilities (SLD) in five high schools in the federally designated economically distressed area called the Illinois Delta Region. A unit of instruction taken from the existing 165 units of The Illinois Core Curriculum for Agriculture was redesigned in a manner appropriate to SLD students. Students from the five selected programs were randomly assigned to treatment and control groups. Results from pre– and posttests in this study found the redesigned curriculum for SLD students effectively increased learning for both SLD and traditional students

Application of Q-methodology in studying construction stakeholders&#039; perceptions of OSH risks - An introduction to the preliminary stage

There is increasing recognition that many construction occupational health and safety (OSH) hazards arise as a result of activities in the planning and design stage. Improvement of construction OSH performance can be influenced by various stakeholder groups, not just the appointed construction contractor. It is important for stakeholder groups to take each other&#039;s perspective when considering OSH risks. However, different stakeholder groups may have different perceptions of OSH risk, leading to difficulty in establishing a common strategy to eliminate hazards and/or and reduce risk. This study aims to map the similarity/difference between stakeholder groups&#039; OSH risk perceptions. An innovative Q-methodology is adopted for data collection. Q-methodology involves a number of procedures by which respondents sort a set of sample objects (known as a Q-set) into certain order, according to their subjective judgements. Photographs will be used as stimuli for the Q-sort in this study. This paper introduces the rationale of Q-methodology, and describes the process of developing and validating the Q-sort instrument for this construction application

Exploring the link between early constructor involvement in project decision-making and the efficacy of health and safety risk control

The position of the constructor in communication networks, including those before the commencement of construction, is likely related to the quality of work health and safety (WHS) outcomes realized. In order to examine the extent of this relationship, 23 cases were drawn from 10 participating construction projects in Australia and New Zealand. Social network analysis was used to mathematically and graphically model information exchanges in 13 of these cases. For each case, the quality of WHS risk control outcomes was measured. This measurement was based on an established &#039;hierarchy of control&#039; in which risk controls are classified in descending order of effectiveness from the elimination of a hazard (the most effective) to the reliance on personal protective equipment (the least effective). Social network metrics were calculated reflecting: (1) the ratio of actual links among parties in the project network relative to the maximum number of links possible (network density); and (2) the extent to which the constructor communicated with other parties in pre-project planning and design stages (the constructors&#039; degree centrality). Network metrics were compared for cases in which the risk control scores were higher and lower than average. The results showed a significant difference in constructors&#039; pre-construction degree centrality for cases with high and low risk control scores. The results provide preliminary evidence as to the potential WHS benefits of ensuring that constructors&#039; knowledge about construction methods, materials, WHS risks and means of risk control, are integrated into pre-construction decision-makin

When groups help and when groups harm: origins, developments, and future directions of the 'social cure' perspective of group dynamics

A substantial literature supports the important role that social group memberships play in enhancing health. While the processes through which group memberships constitute a ‘Social Cure’ are becoming increasingly well-defined, the mechanisms through which these groups contribute to vulnerability and act as a ‘Social Curse’ are less understood. We present an overview of the Social Cure literature, and then go beyond this to show how the processes underpinning the health benefits of group membership can also negatively affect individuals through their absence. First, we provide an overview of early Social Cure research. We then describe later research concerning the potential health benefits of identifying with multiple groups, before moving on to consider the ‘darker side’ of the Social Cure by exploring how intra-group dynamics can foster Curse processes. Finally, we synthesise evidence from both the Cure and Curse literatures to highlight the complex interplay between these phenomena, and how they are influenced by both intra- and inter-group processes. We conclude by considering areas we deem vital for future investigation within the discipline
