Analysis of organomercurials in environmental and biological samples by capillary column gas chromatography with atomic fluorescence detection

The general method for determining organomercurials in environmental and biological samples is gas chromatography with electron capture detection (GC-ECD). However, tedious sample work up protocols and poor chromatographic response show the need for the development of new methods. Here, Atomic Fluorescence-based methods are described, free from these deficiencies. The organomercurials in soil, sediment and tissue samples are first released from the matrices with acidic KBr and cupric ions and extracted into dichloromethane. The initial extracts are subjected to thiosulfate clean up and the organomercury species are isolated as their chloride derivatives by cupric chloride and subsequent extraction into a small volume of dichloromethane. In water samples the organomercurials are pre-concentrated using a sulfhydryl cotton fiber adsorbent, followed by elution with acidic KBr and CuSO 4 and extraction into dichloromethane. Analysis of the organomercurials is accomplished by capillary column chromatography with atomic fluorescence detection.

Relation of health related hardiness to health perception and psychosocial adaptation in adult hispanics with chronic hepatitis C

The purpose of this study was to investigate the role of hardiness in health perception and psychosocial adaptation in adult hispanics with chronic hepatitis C (n = 32). The Health Related Hardiness Scale and the Psychosocial Adaptation to Illness Scale were administered to 32 adult hispanics diagnosed with chronic heptitis C at a gastroenterology center. The results indicate that a comparison of subjects with low and high hardiness scores did not reveal significant differences on any of the PAIS domains (health care orientation, sexual relationships, psychological distress, vocational, domestic and social environments). Furthermore, hardiness subscales of control and committment did not have any influence on patient's psychosocial adaptation nor in its domains. However, a comparison of subjects with low and high challenge scores indicates that those with low challenge had lower total psychosocial adaptation scores (M = 5.55, SD = 2.13) than subjects with high challenge scores (M = 4.24, SD = .67) ,t = (1, 30) = 2.34, p < 0.05. Differences were also found for the domains of health care orientation, psychological distress, social and vocational environment. Lastly, there were significant differences on perceived health rating (poor, fair, and good) for the total hardiness score (F = (2,29) =5.49, p < 0.05), control (F =(2,29) = 4.09, p < 0.05), committment (F=(2,29) = 3.76, p < 0.05) and challenge (F=(2,29)= 4.92, p < 0.05). Thus, those patients who rated their health as poor had lower hardiness levels. Findings have implications for promoting hardiness for better health perception and in certain aspects of psychosocial adaptations in adult hispanics with chronic hepatitis C.

A comparative analysis of school satisfaction and dropout risk of middle school students attending programs for students with emotional handicaps, severe emotional disturbance and general education students attending center schools and satellite schools

This study evaluated school satisfaction as an indicator of dropout risk of students with Emotional Handicaps (EH) and students with Severe Emotional Disturbance (SED). The students attended two different kinds of middle schools in a largely urban school district in South Florida. One hundred eight students in grade 8 (ages 13-16) participated in this study. Participants were administered the National Dropout Prevention Assessment (NDPA). Forty participants with EH and SED attended a special center school. Thirty-one participants with EH and SED attended satellite programs in a regular middle school. Thirty-seven general education participants attended the same regular middle school. Overall school satisfaction scores were generated, as well as three primary factors (school, environment and personal) and 16 subscales (school atmosphere, future income, difficulty level of classwork, teacher relationships, peer relationships, intrinsic interest in classwork, school hours, classwork stress, general attitude towards school, family influence, perceived opportunity for career, future goals, travel distance, leisure time, self-appraisal of performance, and self-esteem).^ Comparison of students with EH and SED revealed that both groups of students were rated at "low risk" of becoming dropouts on the Environmental factor and the Difficulty of Schoolwork subscale. Students with EH were rated at "caution risk" risk on the Travel Distance subscale. Students with SED were rated at "high risk" on this subscale.^ There were no significant differences in school satisfaction and dropout risk between different program delivery models. There were also no significant differences for category of students (EH, SED) by school type (center school, satellite program). All students were rated at "low risk" of dropping out of school.^ There were significant differences between general education students and students with EH and SED attending satellite programs. Students with EH and SED were rated at "caution risk" for dropping out on the Travel Distance and the Leisure Time subscales. Discussion of results, implications for practice and recommendations for further research are included. ^

Characteristics of the Commission on Accreditation of Allied Health Education Programs or National Athletic Trainers' Association -accredited athletic training programs associated with first -attempt passing rates on the NATABOC examination

Athletic training is an allied health profession recognized by the American Medical Association requiring certification by examination. There are two routes towards certification as an athletic trainer: attending a university with an accredited athletic training program or with an internship program By 2004, the only route towards certification will be by attending a Commission on Accreditation of Allied Health Education Programs (CAAHEP) or National Athletic Trainers' Association (NATA) accredited athletic training program. CAAHEP looks at passing rates on the NATA Board of Certification (NATABOC) examination when granting accreditation. This study examined characteristics of programs associated with first time passing rates. ^ Directors from 39 CAAHEP or NATA accredited athletic training programs completed a descriptive 17-question survey regarding academic characteristics, faculty characteristics, and program characteristics. Analysis used Spearman's rho correlation coefficient, with significance of p = <.05. Four program directors were interviewed to gather additional insight. ^ There were three program characteristics that showed a significant positive association with first attempt passing rates: the number of full-time and part-time approved clinical instructors (ACIs), and the number of students in the program. Further investigation found a statistically significant association between a low ratio of ACIs to athletic training students and first time passing rates. ACIs are certified athletic trainers (ATCs) who have received special training in order to supervise athletic training students. CAAHEP mandates a 1:8 ratio of ATCs to athletic training student. This study showed that a smaller ratio of ATC to student in combination with ACI training was significantly associated with higher first time passing rates. The number of courses above the required 13 delineated by the Education Council showed a significant negative association with first attempt passing rates. ^ Universities seeking or maintaining accreditation should incorporate characteristics associated with a higher passing rate on the NATABOC examination. Characteristics include utilizing a large number of full-time and part-time ACIs, admitting a large number of students into the program while maintaining a low ACI to athletic training student ratio, and offering curricula that focuses on the 13 courses that have been deemed relevant to the athletic training curriculum by the Education Council. ^

The effects of health education on student health -related behaviors

During their transitional period from childhood to adulthood, adolescents engage in risk-taking behaviors that become public health concerns. It is important for school health education professionals to design instructional programs that focus on adolescents' developmental needs and foster healthier lifestyles. The goal of health education is to help students acquire health skills that are necessary to succeed in school and in life. This is especially important because the increase in teenagers' risky behaviors can affect their health, well being, and eventually the course of their lives. ^ This study examined the effects of health education on health-related behaviors of public high school students. A multivariate analysis of variance was conducted to determine whether the comprehensive approach based on The Jessors' Problem Behavior Theory (PBT) had a greater impact on adolescents' risk-taking behaviors than the traditional approach. After 18 weeks of health instruction using one of these approaches, the Youth Risk Behavior Survey (YRBS) was administered to measure the level of subjects' self-reported behaviors in six categories of adolescent risky behaviors: the use of tobacco; the use of alcohol and other drugs; engagement in injurious activities; consumption of unhealthy diet; an inadequate level of participation in physical activities; and engagement in risky sexual activities. ^ The results of this study did not support the hypothesis that using the comprehensive health education approach was more influential than the traditional health education approach in improving students' health-risk behaviors. Further research studies based on bio-psychosocial theories are needed to develop and evaluate methods of instruction and delivery of health skills. ^

Advanced Placement and American education: A Foucauldian analysis of the Advanced Placement Program of the college board

Advanced Placement is a series of courses and tests designed to determine mastery over introductory college material. It has become part of the American educational system. The changing conception of AP was examined using critical theory to determine what led to a view of continual success. The study utilized David Armstrong's variation of Michel Foucault's critical theory to construct an analytical framework. Black and Ubbes' data gathering techniques and Braun and Clark's data analysis were utilized as the analytical framework. Data included 1135 documents: 641 journal articles, 421 newspaper articles and 82 government documents. ^ The study revealed three historical ruptures correlated to three themes containing subthemes. The first rupture was the Sputnik launch in 1958. Its correlated theme was AP leading to school reform with subthemes of AP as reform for able students and AP's gaining of acceptance from secondary schools and higher education. The second rupture was the Nation at Risk report published in 1983. Its correlated theme was AP's shift in emphasis from the exam to the course with the subthemes of AP as a course, a shift in AP's target population, using AP courses to promote equity, and AP courses modifying curricula. The passage of the No Child Left Behind Act of 2001 was the third rupture. Its correlated theme was AP as a means to narrow the achievement gap with the subthemes of AP as a college preparatory program and the shifting of AP to an open access program. ^ The themes revealed a perception that progressively integrated the program into American education. The AP program changed emphasis from tests to curriculum, and is seen as the nation's premier academic program to promote reform and prepare students for college. It has become a major source of income for the College Board. In effect, AP has become an agent of privatization, spurring other private entities into competition for government funding. The change and growth of the program over the past 57 years resulted in a deep integration into American education. As such the program remains an intrinsic part of the system and continues to evolve within American education. ^

A frame analysis of the leadership styles of dental and medical school deans

The purpose of this study was to determine how dental and medical school deans perceived their own leadership styles and how many management/leadership perspectives they used when approaching a problem. A descriptive and correlational study was conducted which examined the leadership orientations or "frames" utilized by these deans. Four frames--the structural, the human resource, the political, and the symbolic--emerged from leadership studies which described the behavior of leaders in organizational actions and problem solving.^ Employing the repeated measures ANCOVA, it was found that there were no significant interactions between type of dean and perceptions or perspectives. However, the main effects of both leadership style perceptions and the use of perspectives were significant. This indicated that over the total sample of deans, both perceptions and perspectives were used differently; the deans perceived themselves and used perspectives the highest for the human resource frame and the lowest for the political frame. Also, dental deans' mean use overall of the four perspective frames was higher than the medical deans. In addition to the ANCOVA, t-tests performed on perceptions revealed that the deans perceived the frames differently in three human resource items. Pearson's correlations indicated that for the combined sample of deans, significant negative correlations existed when the human resource or symbolic frame was compared to the structural frame. All of the deans used multiple frames, allowing them to re-frame or combine frames according to the situation. ^
