Price, Travis Miles. "Emotional Intelligence in Medical Laboratory Science." DigitalCommons@USU, 2013. https://digitalcommons.usu.edu/etd/1711.
Full textAbstract:
The purpose of this study was to explore the role of emotional intelligence (EI) in medical laboratory science, as perceived by laboratory administrators. To collect and evaluate these perceptions, a survey was developed and distributed to over 1,400 medical laboratory administrators throughout the U.S. during January and February of 2013. In addition to demographic-based questions, the survey contained a list of 16 items, three skills traditionally considered important for successful work in the medical laboratory as well as 13 EI-related items. Laboratory administrators were asked to rate each item for its importance for job performance, their satisfaction with the item's demonstration among currently working medical laboratory scientists (MLS) and the amount of responsibility college-based medical laboratory science programs should assume for the development of each skill or attribute. Participants were also asked about EI training in their laboratories and were given the opportunity to express any thoughts or opinions about EI as it related to medical laboratory science. This study revealed that each EI item, as well as each of the three other items, was considered to be very or extremely important for successful job performance. Administrators conveyed that they were satisfied overall, but indicated room for improvement in all areas, especially those related to EI. Those surveyed emphasized that medical laboratory science programs should continue to carry the bulk of the responsibility for the development of technical skills and theoretical knowledge and expressed support for increased attention to EI concepts at the individual, laboratory, and program levels.

Full textAbstract:
Histology as a career offers many challenging and diverse job opportunities but few qualified applicants pursue this vocation. The purpose of this research was to collect data to identify factors impacting this problem. The study investigated the awareness, attitudes and perceptions of community college and university science students towards laboratory health science and histology as a career option. The goal was to develop strategies to identify and recruit potential individuals who are qualified for the histology profession. The researcher surveyed 15 undergraduate science classes from two community colleges and one university in the Midwest. The community colleges and university surveyed offer academic course work necessary for a student to pursue a career in histology. The survey was designed to collect data regarding the student's attitudes toward career preparedness, job opportunities, anticipated salary, and laboratory science employment. Results of this study support the hypothesis that undergraduate students pursuing science degrees are potential candidates for careers in histology but they are unaware of the profession. The study also provides a preliminary needs-assessment to support the development of programs that offer histology training for undergraduate and graduate students pursuing college science degrees.

Full textAbstract:
The goal of primary science education is to foster children’s interest, develop positive science attitudes and promote science process skills development. Learning by playing and discovering provides several opportunities for children to inquiry and understand science based on the first–hand experience. The current research was conducted in the children’s laboratory in Heureka, the Finnish science centre. Young children (aged 7 years) which came from 4 international schools did a set of chemistry experiments in the laboratory. From the results of the cognitive test, the pre-test, the post-test, supported by observation and interview, we could make the conclusion that children enjoyed studying in the laboratory. Chemistry science was interesting and fascinating for young children; no major gender differences were found between boys and girls learning in the science laboratory. Lab work not only encouraged children to explore and investigate science, but also stimulated children’s cognitive development.

Full textAbstract:
When viewed as a product rather than a process that aids in student learning, the lab report may become rote, busywork for both students and instructors. Students fail to see the purpose of the lab report, and instructors see them as a heavy grading load. If lab reports are taught as part of a process rather than a product that aims to "get the right answer," they may serve as pedagogical tools in college science courses. In response to these issues, an in-depth, web-based tutorial named LabWrite (www.ncsu.edu/labwrite) was developed to help students and instructors (www.ncsu.edu/labwrite/instructors) understand the purpose of the lab report as grounded in the written discourse and processes of science. The objective of this post-test only quasi-experimental study was to examine the role that in-depth instruction such as LabWrite plays in helping students to develop skills characteristic of scientifically literate individuals. Student lab reports from an introductory-level biology course at NC State University were scored for overall understanding of scientific concepts and scientific ways of thinking. The study also looked at students? attitudes toward science and lab report writing, as well as students? perceptions of lab reports in general. Significant statistical findings from this study show that students using LabWrite were able to write lab reports that showed a greater understanding of scientific investigations (p<.003) and scientific ways of thinking (p<.0001) than students receiving traditional lab report writing instruction. LabWrite also helped students develop positive attitudes toward lab reports as compared to non-LabWrite users (p<.01). Students using LabWrite seemed to perceive the lab report as a valuable tool for determining learning objectives, understanding science concepts, revisiting the lab experience, and documenting their learning.

Full textAbstract:
The purpose of this project is to create a measurement system aimed for a laboratory environment at Uppsala University. The measurement system will be used by students for laboratories of electrical science. It will include a measurement station and an application that will be used by the students. A specification of 16 channels of measuring data, 8 current and 8 voltage, was given by the client. Beside this specification there were 8 others to fulfil. The measurement station is connected to a compactRIO which will enable the possibility to graphically and numerically represent the results through an application created in Labview. The application will include time and phasor representations of both current and voltage. It will also include two power vectors for 6 channels each. The result of this project is a fully working measurement system which generates a good overview of measurements made on an electrical power system. All given specifications was fulfilled except one, which was not possible to achieve with the chosen methodology.

Full textAbstract:
Teachers for generations have struggled with the challenge of motivating students to learn in their classes. Literature suggests that a positive way to increase student motivation and academic achievement in science is with the laboratory experience. With the lack of adequate laboratory space in our schools, teachers are having to "make do" in science classes with limited space and budget. A need exists for 9th grade Earth Science laboratory activities that meet county course objectives and yet are simple enough to be used in a classroom setting, thereby eliminating the need for extra expenses for the science department. This project has developed a set of laboratory experiences appropriate for 9th grade Earth Science courses in Duval County.

Madan, Nilia M. "Predictors of Success: Medical Laboratory Associate in Science Degree Program." FIU Digital Commons, 2012. http://digitalcommons.fiu.edu/etd/672.
Full textAbstract:
Hospitals and healthcare facilities in the United States are facing serious shortages of medical laboratory personnel, which, if not addressed, stand to negatively impact patient care. The problem is compounded by a reduction in the numbers of academic programs and resulting decrease in the number of graduates to keep up with the increase in industry demands. Given these challenges, the purpose of this study was to identify predictors of success for students in a selected 2-year Medical Laboratory Technology Associate in Science Degree Program.
This study examined five academic factors (College Placement Test Math and Reading scores, Cumulative GPA, Science GPA, and Professional [first semester laboratory courses] GPA) and, demographic data to see if any of these factors could predict program completion. The researcher examined academic records for a 10-year period (N =158). Using a retrospective model, the correlational analysis between the variables and completion revealed a significant relationship (p < .05) for CGPA, SGPA, CPT Math, and PGPA indicating that students with higher CGPA, SGPA, CPT Math, and PGPA were more likely to complete their degree in 2 years. Binary logistic regression analysis with the same academic variables revealed PGPA was the best predictor of program completion (p < .001).
Additionally, the findings in this study are consistent with the academic part of the Bean and Metzner Conceptual Model of Nontraditional Student Attrition which points to academic outcome variables such as GPA as affecting attrition. Thus, the findings in this study are important to students and educators in the field of Medical Laboratory Technology since PGPA is a predictor that can be used to provide early in-program intervention to the at-risk student, thus increasing the chances of successful timely completion.

The reproducibility of a measurement in a laboratory test impacts on the power of that test to detect the small, but significant changes in an athlete's performance when determining the influence of a new training or nutritional intervention. Until recently, however, sport scientists have not been concerned with establishing the reliability of many of their testing protocols. Therefore, the purpose of this thesis was to examine the reliability of several laboratory tests of performance and to determine those factors which may impact on the reproducibility of those tests. Possible factors that could contribute to the reliability of a performance test include the type of exercise protocol employed (continuous, intermittent), the equipment on which the subject performs the test, the intensity and duration of the testing protocol, the subject's state of fitness and whether he is familiar with the testing conditions.

Full textAbstract:
Retiring baby boomers and the lack of interest and awareness among college students to enroll in an accredited Clinical Laboratory Science (CLS) program have created a shortage of CLS professionals in the 21st century. The U.S. Bureau of Labor Statistics predicts 18,000 CLS vacancies by 2018. However, only about 5,000 students graduate from accredited CLS programs each year. The purpose of this study was to explore students' perceptions of allied health professions and factors that influenced students and CLS professionals to select CLS as a profession. Bandura's social cognitive career theory served as the theoretical framework for this phenomenological study. Convenient purposeful sampling was used to select the 7 CLS professionals, 5 high school students, and 5 college students in the Chicago area. Participants took part in either a 30- to 60-minute group session or a 45- to 90-minute semi structured interview. Qualitative analysis included open axial coding to identify emerging patterns and themes from the transcripts. Findings revealed that the perceptions of both high school and college students' knew little about the CLS profession, and factors influencing CLS as a career choice included interests in science, health care, and family. CLS professionals indicated their interests in science and a high demand for CLS services in the workforce led them to pursue careers in the field. Implications for social change include improving professional-development programs for student awareness of allied health professions and mitigating the shortage of clinical laboratory scientists.

Full textAbstract:
The purpose of this action research was to study the effects of laboratory-based activities on student attitudes toward science. For the purpose of this study, fifth grade students were taught science over a five month period which included the regular science curriculum for the school district, labs from the science series, and additional labs corresponding to the topics in the curriculum that were developed by the teacher or other professionals. Students were given questionnaires and surveys at the beginning and end of the five month period. Surveys and questionnaires included questions about favorite subjects, what was best about science, and how the student understands science. Comments on what kind of lab/activity was most beneficial to increase understanding and what type of lab or activity was preferred were examined. Pre and post data were compared to determine whether or not student attitude toward science changed after the five month period. Although students entered this fifth grade classroom with a good attitude toward science, there was a noticeable increase in science attitude in regard to favorite subject and understanding of science at the end of the time period. The importance of using labs/activities to inspire and increase understanding of science in fifth grade was evident not only in survey results but from statements students made as well.

Based on the importance place of metacognition in education, the current study aimed to investigate whether the embedded metacognitive prompts in the manual lead a change in PSTs&rsquo<br>metacognitive knowledge and metacognitive skills. Throught 2009-2010 Fall semester, the data were collected from pre-service science teachers (PSTs) who enrolled in the Laboratory Applications in Science Education course. The course was offered as a must course in Elementary Science Education programme in one of the biggest universites in Ankara. The method selected for the study was mix method. Both quantitative and qualitative data were collected and analyzed. Quantitative data was collected from 28 PSTs and qualitative data was collected from 7 PSTs who were the members of the researcher&rsquo<br>s group. In accordance with the purpose of the current study, descriptive statistics and independent samples t-test was conducted for quantitative data. In terms of qualitative part, the study was case study and interviews which were conducted before and after the course were analyzed to observe the change of PSTs&rsquo<br>metacognition.
The result of the study revealed that before the course most of the PSTs did not report metacognitive skills. After the course it was observed that their metacognitive skills were developed. Among metacognitive skills, the most reported skill was monitoring skill after the course. It can be concluded from the study that metacognitive prompts embedded into the manual provided a metacognitively learning environment and a development in PSTs&rsquo<br>metacognition.

Full textAbstract:
Despite considerable research on cancer treatments and preventatives, poor outcomes in cancer patients are common. The vital search for effective cancer drugs often begins in the laboratory, where unfortunately the effects of a drug in humans cannot be perfectly modelled. Epidemiology can play a vital role in determining the real world efficacy of a drug currently used for other purposes before clinical trials begin. This thesis therefore used primarily laboratory evidence to identify potential anti-cancer uses for existing common drugs. The drugs and cancers studied were; tricyclic antidepressants and both incidence and survival in a number of cancer types, particularly glioma; aspirin and colorectal cancer survival; and angiotensin converting enzyme (ACE) inhibitors and hepatocellular carcinoma (HCC) incidence. A series of studies using The General Practice Research Database as a data source assessed any potential associations: A case-control study for tricyclic antidepressant use and cancer incidence; cohort studies to examine mortality in colorectal cancer and glioma in relation to tricyclic use, and for colorectal cancer mortality in aspirin users; and a case-control study in relation to ACE inhibitor use and HCC. A strong, cancer type specific, dose and time dependant protective effect was found for the incidence of glioma and colorectal cancer. This led to a further study examining mortality for these cancer types in tricyclic users. While no significant protective effects in all-cause mortality of tricyclic users were found, a larger study could still find such an effect in glioma. For aspirin and colorectal cancer mortality, a small but significant reduction in mortality was observed, though these effects were not entirely consistent throughout the study. There were no significant associations found between ACE inhibitors and HCC. These findings contribute to the knowledge of the anti-cancer effectiveness of these drugs, and may assist in designing future clinical studies.

Thesis (M. A. (English Studies)) --University of Limpopo, 2020<br>Conventional laboratory report writing skills present an enormous challenge to first
entering science students including the Bachelor of Science (BSc) students at Sefako
Makgatho Health Sciences University (SMHSU). First entering students are expected
to meet essential tertiary discourse requirements and standards consistent with their
scientific community. The purpose of this study was to explore how content lecturers
in cognate departments assess laboratory report writing skills of first entering BSc
students. The research design was exploratory and a mixed approach was used.
Students sat for a criterion-referenced test and interviews were conducted with content
lecturers to collect data; quantitative basic statistical interrogation of the basic data
points and post interview analysis were performed. Some of the key findings of this
exploration was that most first entering BSc students are in a dire situation regarding
the laboratory report writing genre; they are unable to communicate comprehensive
and intelligible information in the written laboratory reports. Thus, content lecturers
and English language lecturers from the Department of Language Proficiency (DLP)
need to strategically collaborate in order to improve the performance of first entering
BSc students.

This thesis is the product of a knowledge acquisition effort, whose objective was to obtain information essential to the modelling and simulation of a robotically operated laboratory on board the forthcoming space station "Freedom." The information is represented using the system entity structure, a knowledge representation scheme that utilizes artificial intelligence concepts. The system entity structure details the design information and associated knowledge required for the intelligent autonomous operation of the space-based laboratory. The approach is proven to be very beneficial for organizing and displaying the vast amounts of information that constitute this intricate system design. Knowledge management, representation, and the nature of a future software implementation are also addressed.

Full textAbstract:
<p>Achievement data from the 3<i>rd</i> International Mathematics and Sciences Study and Program for International Student Assessment in science have indicated that Black students from economically disadvantaged families underachieve at alarming rates in comparison to White and economically advantaged peer groups. The study site was a predominately Black, urban school district experiencing underachievement. The purpose of this correlational study was to examine the relationship between students’ use of inquiry-based laboratory investigations and their performance on the Biology End of Course Test, as well as to examine the relationship while partialling out the effects of student gender. Constructivist theory formed the theoretical foundation of the study. Students’ perceived levels of experience with inquiry-based laboratory investigations were measured using the Laboratory Program Variable Inventory (LPVI) survey. LPVI scores of 256 students were correlated with test scores and were examined by student gender. The Pearson correlation coefficient revealed a small direct correlation between students’ experience in inquiry-based laboratory investigation classes and standardized test scores on the Biology EOCT. A partial correlational analysis indicated that the correlation remained after controlling for gender. This study may prompt a change from teacher-centered to student-centered pedagogy at the local site in order to increase academic achievement for all students. The results of this study may also influence administrators and policy makers to initiate local, state, or nationwide curricular development. A change in curriculum may promote social change as students become more competent, and more able, to succeed in life beyond secondary school. </p>

Full textAbstract:
This thesis examines user interaction with instrumentation in the specific context of space science. It gathers together existing practice in machine interfaces with a look at potential future usage and recommends a new approach to space science projects with the intention of maximising their science return. It first takes a historical perspective on user interfaces and ways of defining and measuring the science return of a space instrument. Choices of research methodology are considered. Implementation details such as the concepts of usability, mental models, affordance and presentation of information are described, and examples of existing interfaces in space science are given. A set of parameters for use in analysing and synthesizing a user interface is derived by using a set of case studies of diverse failures and from previous work. A general space science user analysis is made by looking at typical practice, and an interview plus persona technique is used to group users with interface designs. An examination is made of designs in the field of astronomical instrumentation interfaces, showing the evolution of current concepts and including ideas capable of sustaining progress in the future. The parameters developed earlier are then tested against several established interfaces in the space science context to give a degree of confidence in their use. The concept of a simulator that is used to guide the development of an instrument over the whole lifecycle is described, and the idea is proposed that better instrumentation would result from more efficient use of the resources available. The previous ideas in this thesis are then brought together to describe a proposed new approach to a typical development programme, with an emphasis on user interaction. The conclusion shows that there is significant room for improvement in the science return from space instrumentation by attention to the user interface.

Full textAbstract:
<p> The increased surface melting of the outlet glaciers of the Vatnajökull Ice Cap has a profound affect on the dynamics of the ice-bed couple and landform genesis. Soft-bedded glaciers are largely inaccessible, which creates a problem. One challenge is to understand the complex interactions of the glacier bed and its resultant depositional and deformational landform systems. This study investigates an outlet glacier from the Vatnajökull Ice Cap, described herein as the Fláajökull glacier system. To circumvent some of these problems, three separate projects were conducted in this dissertation: (1) magnetic fabric study of effective pressure (difference between the ice-overburden pressure and pore-water pressure) and shear rate (glacier velocity) using a laboratory ring-shear device; (2) glaciological analysis of magnetic fabrics and c-axis orientations of dirty ice veins; and (3) investigation of drumlin formation using magnetic till fabrics and field relationships. Several hypotheses were addressed for each of these studies, which include: (1) to determine if fabric strength is independent of shear rate and effective pressure. This hypothesis was tested and the results confirmed that the fabric strength (S1 eigenvalue) was independent of shear rate and effective pressure. Based on these results, effective pressure and shear rate cannot be interpreted from fabric strength evidence from glacial deposits; (2) in the glaciological study, I hypothesized that the dirty ice veins were sub-vertically sheared from the bed near the ice front, but then moderately deformed. Results from the magnetic fabrics indicate that the maximum K1 susceptibility axis (77° plunge) is approximately parallel to the vein margins verify that the injection was sub-vertical. The long axes of the recrystallized ice grains (parallel to foliation plane defined by K<sub>1</sub> – K<sub>2</sub>) appeared to show a good correlation with the plunge of the maximum K<sub>1</sub> susceptibility. Also, the eigenvector plunge of the c-axes was approximately normal to the shear plane, which supports previous theory that c-axes rotate away from the shear plane toward the vertical. Multi-maximum girdle fabrics from the c-axes and associated textures from thin sections (e.g. nucleated grains, bulging of grain boundaries and slips band) suggest that some deformation likely occurred after emplacement; and (3) the Boulton hypothesis was tested using magnetic till fabrics and field relationships. According to this idea, drumlins form due to hydrologic heterogeneity (permeability differences in granular materials) causing a solid nucleus to form in the bed where sediment is accreted and sheared in the direction of ice flow. At Fláajökull, the magnetic fabrics from sites B and C mimicked the glacier flow direction with the longitudinal flow plane (K<sub>1</sub> – K<sub>3</sub>) approximately parallel to the NNW-SSE drumlin long axis. The drumlin cores consisted of outwash sand and gravels which likely acted as rigid obstacles in the bed. Ice overriding resulted in heterogeneous deformation of the drumlin cores following the deposition of the upper basal till carapace. These results support the Boulton hypothesis. </p><p> These studies demonstrate significant progress toward understanding fabric strength development of soft-bedded glaciers. In linking studies (1) and (3) the ring-shear device was used to provide insights into fabric strength development upon shear rate and effective pressure. In the third study previous ring-shear experiments, magnetic till fabrics and field relationships were used to understand modern drumlin genesis.</p>

Full textAbstract:
This study examined an innovative, project-based curriculum in a freshman biology laboratory by focusing on how students developed their conceptual understanding of a biological species. A model for learning was posed based on learners working in small groups. This model linked a sociocultural approach to teaching and learning to conceptual change theory. Qualitative research methods were employed to collect a variety of data. Documentation of this innovative curriculum is provided.
This investigative curriculum incorporated the research practices that scientists use. A wide range of dynamic interactions with students actively investigating problems and sharing both their findings and thoughts during this time occurred. This essentially modeled the authentic practices of scientists. A direct comparison was made with this learning environment and the model for learning. Peer tutoring, cooperative learning, and most importantly, peer collaboration were observed when students grappled with difficult problems for which there was no single right answer. Teachers served as guides in learning, shifting responsibility to the students.
Analysis of student writing revealed richer, more complex definitions of species after the experience of the laboratory project. Several of the students used knowledge gained directly from their experiences during the laboratory project to help elaborate their definitions.
The electronic discussions showed a range of social interactions and interactivity. High quality discussions were found to be rich in scientific thought, engaging discussants by offering information, questioning, and actively hypothesizing. Mediating and facilitating discussions by the participants was found to be an important factor in their success. Groups exhibiting high quality discussions also had a lower response time than other groups, indicating that more substantive dialogues which are rich in thought proceed at a slower pace.
Significantly, an important connection has been made between the socio-cultural approach to learning and conceptual change theory. A closer examination of how small groups of learners develop conceptual understanding is needed. This approach also needs to be extended into other settings where reform in science education is taking place.<br>Ph. D.
