Dounas-Frazer, Dimitri R.; Stanley, Jacob T.; Lewandowski, H. J.

2017-12-01

We investigate students' sense of ownership of multiweek final projects in an upper-division optics lab course. Using a multiple case study approach, we describe three student projects in detail. Within-case analyses focused on identifying key issues in each project, and constructing chronological descriptions of those events. Cross-case analysis focused on identifying emergent themes with respect to five dimensions of project ownership: student agency, instructor mentorship, peer collaboration, interest and value, and affective responses. Our within- and cross-case analyses yielded three major findings. First, coupling division of labor with collective brainstorming can help balance student agency, instructor mentorship, and peer collaboration. Second, students' interest in the project and perceptions of its value can increase over time; initial student interest in the project topic is not a necessary condition for student ownership of the project. Third, student ownership is characterized by a wide range of emotions that fluctuate as students alternate between extended periods of struggle and moments of success while working on their projects. These findings not only extend the literature on student ownership into a new educational domain—namely, upper-division physics labs—they also have concrete implications for the design of experimental physics projects in courses for which student ownership is a desired learning outcome. We describe the course and projects in sufficient detail that others can adapt our results to their particular contexts.

A Deliberate Practice Instructional Approach for Upper Division Physics Courses

Science.gov (United States)

Jones, David

2015-05-01

In upper division physics courses, an overarching educational goal is to have students think about and use the material much as a practicing physicist in the field does. Specifically, this would include knowledge (such as concepts, formalism, and instruments), approaches, and metacognitive skills that physicists use in solving ``typical'' (research context) problems to both understand and predict physical observations and accompanying models. Using an interactive instructional approach known as deliberate practice (described earlier in this session) we will discuss our work on how to provide students with the necessary practice and feedback to achieve these skills in a core DAMOP course of modern optics. We present the results of a direct and explicit comparison between this approach and traditional lecture-based instruction revealing evidence that a significant improvement of the students' mastery of these skills occurs when deliberate practice is employed. Our work was supported by the University of British Columbia through the CWSEI.

Upper-division student difficulties with the Dirac delta function

Directory of Open Access Journals (Sweden)

Bethany R. Wilcox

2015-03-01

Full Text Available The Dirac delta function is a standard mathematical tool that appears repeatedly in the undergraduate physics curriculum in multiple topical areas including electrostatics, and quantum mechanics. While Dirac delta functions are often introduced in order to simplify a problem mathematically, students still struggle to manipulate and interpret them. To characterize student difficulties with the delta function at the upper-division level, we examined students’ responses to traditional exam questions and a standardized conceptual assessment, and conducted think-aloud interviews. Our analysis was guided by an analytical framework that focuses on how students activate, construct, execute, and reflect on the Dirac delta function in the context of problem solving in physics. Here, we focus on student difficulties using the delta function to express charge distributions in the context of junior-level electrostatics. Common challenges included invoking the delta function spontaneously, translating a description of a charge distribution into a mathematical expression using delta functions, integrating 3D or non-Cartesian delta function expressions, and recognizing that the delta function can have units. We also briefly discuss implications of these difficulties for instruction.

Caballero, Marcos D.; Wilcox, Bethany R.; Pepper, Rachel E.; Pollock, Steven J.

2013-01-01

At the University of Colorado Boulder, as part of our broader efforts to transform middle- and upper-division physics courses, we research students' difficulties with particular concepts, methods, and tools in classical mechanics, electromagnetism, and quantum mechanics. Unsurprisingly, a number of difficulties are related to students' use of mathematical tools (e.g., approximation methods). Previous work has documented a number of challenges that students must overcome to use mathematical tools fluently in introductory physics (e.g., mapping meaning onto mathematical symbols). We have developed a theoretical framework to facilitate connecting students' difficulties to challenges with specific mathematical and physical concepts. In this paper, we motivate the need for this framework and demonstrate its utility for both researchers and course instructors by applying it to frame results from interview data on students' use of Taylor approximations.

Prokopy, Max P; Ingersoll, Christopher D; Nordenschild, Edwin; Katch, Frank I; Gaesser, Glenn A; Weltman, Arthur

2008-11-01

Closed-kinetic chain resistance training (CKCRT) of the lower body is superior to open-kinetic chain resistance training (OKCRT) to improve performance parameters (e.g., vertical jump), but the effects of upper-body CKCRT on throwing performance remain unknown. This study compared shoulder strength, power, and throwing velocity changes in athletes training the upper body exclusively with either CKCRT (using a system of ropes and slings) or OKCRT. Fourteen female National Collegiate Athletic Association Division I softball player volunteers were blocked and randomly placed into two groups: CKCRT and OKCRT. Blocking ensured the same number of veteran players and rookies in each training group. Training occurred three times weekly for 12 weeks during the team's supervised off-season program. Olympic, lower-body, core training, and upper-body intensity and volume in OKCRT and CKCRT were equalized between groups. Criterion variables pre- and posttraining included throwing velocity, bench press one-repetition maximum (1RM), dynamic single-leg balance, and isokinetic peak torque and power (PWR) (at 180 degrees x s(-1)) for shoulder flexion, extension, internal rotation, and external rotation (ER). The CKCRT group significantly improved throwing velocity by 2.0 mph (3.4%, p performance. Strength coaches can incorporate upper-body CKCRT without sacrificing gains in maximal strength or performance criteria associated with an athletic open-chain movement such as throwing.

The current impact of entry-level associate and baccalaureate degree education on the diversity of respiratory therapists.

Science.gov (United States)

Becker, Ellen A; Nguyen, Xuan T

2014-12-01

Transitioning from an associate degree to a baccalaureate degree for respiratory therapists has been suggested as a new entry-level educational standard. One potential risk for this change is that it may limit the diversity of potential applicants for entry-level education. A diverse workforce is important to achieve the goal of reducing healthcare disparities. This study evaluated characteristics of therapists who completed associate and baccalaureate degree entry-level education. A secondary analysis of data collected from the 2009 AARC Respiratory Therapist Human Resource Survey explored relationships between the choice of entry-level associate or baccalaureate education and variables of gender, race, salary, career advancement, and job satisfaction. There were no differences between therapists with entry-level associate and baccalaureate degrees in gender, race, number of additional healthcare credentials, numbers of life support credentials, wages, delivering respiratory care by protocol, and job satisfaction. There were significantly higher percentages of advanced academic degrees, desire to pursue a higher academic degree, registered respiratory therapist credentials, total National Board for Respiratory Care credentials, and leadership roles for therapists with baccalaureate entry-level degrees. Current entry-level associate and baccalaureate degree graduates have similar gender and race proportions. This finding challenges concerns that an entry-level baccalaureate degree would decrease the diversity of the respiratory therapist workforce. Copyright © 2014 by Daedalus Enterprises.

Burke, Mary S

2009-01-01

The concept of technology-related stress was first introduced in the 1980s when computers became more prevalent in the business and academic world. Nurse educators have been impacted by the rapid changes in technology in recent years. A review of the literature revealed no research studies that have been conducted to investigate the incidence of technological stress among nurse educators. The purpose of this descriptive-correlational study was to describe the technological stressors that Louisiana baccalaureate nurse educators experienced while teaching nursing theory courses. A researcher-developed questionnaire, the nurse educator technostress scale (NETS) was administered to a census sample of 311 baccalaureate nurse educators in Louisiana. Findings revealed that Louisiana baccalaureate nurse educators are experiencing technological stress. The variable, perceived administrative support for use of technology in the classroom, was a significant predictor in a regression model predicting Louisiana baccalaureate nurse educators' technological stress (F=14.157, p<.001).

Baccalaureate nursing education at extension sites: a survey.

Science.gov (United States)

Tiffany, J C; Burson, J Z

1986-03-01

The use of extension sites in baccalaureate nursing education has increased significantly since 1978. This survey found that the majority of extension sites were developed for RNs although large numbers of generic students are also served. The use of extension sites ranges from delivering selected courses away from the lead campus to delivering an entire program. Extension sites may be located on other university campuses or may be found in a store front setting or other community agency. Administrative control of extension sites emanates from the lead campus. Faculty participation in faculty activities, such as school of nursing or university committees, is expected. The degree to which this is accomplished, however, may vary. In order to maintain program integrity, the curriculum must remain the same regardless of where it is implemented. One of the primary ways of doing this is to use the same syllabi, texts and, in many cases, the same exams. Faculty may be stationary at established extended sites or may travel from the lead campus to teach, carrying with them educational materials. Extension sites are a phenomenon of the here and now. They provide a way of delivering baccalaureate nursing education to students who might otherwise be denied this level of education. Extension sites may be operationally cumbersome, challenging, and costly, but they are meeting a need. With the advent of more sophisticated telecommunications and the continued demand for baccalaureate level education, the possibility exists for even greater variation and potential for this type of program.

2015-01-01

The purpose of this national study was to explore the vision of chief academic officers for baccalaureate nursing education. We invited chief academic nursing officers, randomly selected from a representative sample of accredited baccalaureate nursing programs to participate in the study. Audiotaped interviews were conducted in focus groups at professional meetings or by telephone and were transcribed verbatim. Data collection continued until thematic saturation was reached (N = 29). Analysis of the findings revealed themes that described future vision for baccalaureate education that provides guidance to faculty as they develop curriculum. An overarching theme "We are all Stewards of the Profession" and three supporting themes emerged: "Learning Pathways are Varied," "Faculty Need to Grow," and "New Pedagogies Need to Focus on the Development of 'Who I Am' as a Clinical Scholar." Findings point to a future where diverse learning pathways are integrated throughout the curriculum. The curriculum of tomorrow will place greater emphasis on the development of professional identity as a nurse and calls for expanded stewardship for nursing education. Deans recommended that investing time and resources into well-designed faculty development programs will help all faculty, regardless of appointment, to adapt to changing student needs and rapidly evolving practice environments.

Kanji, Zul; Sunell, Susanne; Boschma, Geertje; Imai, Pauline; Craig, Bonnie J

2011-03-01

There is little published literature about the outcomes of dental hygiene baccalaureate degree education, particularly in Canada. Since there are various dental hygiene entry-to-practice educational models in Canada, exploring baccalaureate dental hygiene education is becoming an increasingly important subject. The purpose of this study was to explore the personal outcomes and dental hygiene practice outcomes of dental hygiene degree-completion education in Canada from the perspectives of diploma dental hygienists who have continued their education to the bachelor's degree level. This study employed a qualitative phenomenological design, using a maximum variation purposeful sampling strategy. Data generation occurred with sixteen dental hygienists across Canada through individual semistructured interviews. Interviews were audiorecorded, transcribed verbatim, and coded for data analysis, involving pattern recognition and thematic development. Themes that emerged included changes in self-perception, values, and knowledge base. Changes in self-perception were reflected in a reported increase in self-confidence and perceived credibility. Changes in values included a greater appreciation for lifelong learning. Advancements in knowledge strengthened the development of specific abilities that ultimately influenced participants' dental hygiene practice. These abilities included an increased ability to think critically, to make evidence-based decisions, and to provide more comprehensive care. Participants also commented on having more career opportunities available to them outside of the private clinical practice setting. These results reveal important insights into the impact of earning a dental hygiene baccalaureate degree on oneself and one's dental hygiene practice.

Role of the Land Valuation Division in Property Rating by District Assemblies in Ghana's Upper East Region

Directory of Open Access Journals (Sweden)

Maxwell Kwotua Petio

2013-05-01

Full Text Available District Assemblies in Ghana are charged with the responsibility of developing their areas of jurisdiction mainly through internally mobilised revenue. As a consequence, the assemblies are empowered by various pieces of legislation to impose local taxes within their jurisdiction. The local taxes include property rates which are a form of tax that only the District Assemblies may levy. The study therefore looked at the levying of property rates in the Upper East Region and assessed the role and institutional capacity of the Land Valuation Division of the Lands Commission in the tax administration. Findings included limited coverage of the tax, use of flat rates due to absence of up-to-date property values, inadequate technical personnel and logistics for the Land Valuation Division (LVD and lack of political will to levy the rates fully. Relevant suggestions are made, such as the need to introduce mass valuation, widen the tax coverage, establish a fund for revaluation and revive the Valuation Training School, as well as provide requisite logistics for efficient performance of the LVD.

Dunagan, Pamela B; Kimble, Laura P; Gunby, Susan Sweat; Andrews, Margaret M

2016-06-01

Attitudes of prejudice in nursing students have the potential to impact patient care and ultimately may contribute to culturally based health disparities. The purpose of this study was to describe attitudes of prejudice reported by baccalaureate nursing students. Baccalaureate nursing students were recruited through Web networking and e-mailing. Participants responded to a Web-based survey that contained an open-ended item requesting them to describe a time when they held an attitude of prejudice. Qualitative data were coded and analyzed for themes. The majority of participants (N = 50) were women (86%) and White (68%). Qualitative data analysis revealed two major themes: Prejudice Against Obese Individuals, and Prejudice Against Someone of Another Race. Many of the participants had insight that prejudice was wrong and they wanted to change. Acknowledging prejudice, as an explicit bias, is an important step toward cultural competence. Teaching strategies focused on addressing explicit and implicit bias are warranted. [J Nurs Educ. 2016;55(6):345-348.]. Copyright 2016, SLACK Incorporated.

Advancing Pre-Health Humanities as Intensive Research Practice: Principles and Recommendations from a Cross-Divisional Baccalaureate Setting.

Science.gov (United States)

Singer, Sarah Ann; Weed, Kym; Edwell, Jennifer; Jack, Jordynn; Thrailkill, Jane F

2017-12-01

This essay argues that pre-health humanities programs should focus on intensive research practice for baccalaureate students and provides three guiding principles for implementing it. Although the interdisciplinary nature of health humanities permits baccalaureate students to use research methods from the natural sciences, social sciences, and humanities, pre-health humanities coursework tends to force students to adopt only one of many disciplinary identities. Alternatively, an intensive research approach invites students to critically select and combine methods from multiple (and seemingly opposing) disciplines to ask and answer questions about health problems more innovatively. Using the authors' experiences with implementing health humanities baccalaureate research initiatives at The University of North Carolina at Chapel Hill, the authors contend that pre-health humanities programs should teach and study multiple disciplinary research methods and their values; examine how health humanities research might transfer across disciplines; and focus on mentoring opportunities for funding, presenting, and publishing research. These recommendations have the potential to create unprecedented research experiences for baccalaureate students as they prepare to enter careers within and beyond the allied health professions.

Validation and analysis of the coupled multiple response Colorado upper-division electrostatics diagnostic

Directory of Open Access Journals (Sweden)

Bethany R. Wilcox

2015-11-01

Full Text Available Standardized conceptual assessment represents a widely used tool for educational researchers interested in student learning within the standard undergraduate physics curriculum. For example, these assessments are often used to measure student learning across educational contexts and instructional strategies. However, to support the large-scale implementation often required for cross-institutional testing, it is necessary for these instruments to have question formats that facilitate easy grading. Previously, we created a multiple-response version of an existing, validated, upper-division electrostatics diagnostic with the goal of increasing the instrument’s potential for large-scale implementation. Here, we report on the validity and reliability of this new version as an independent instrument. These findings establish the validity of the multiple-response version as measured by multiple test statistics including item difficulty, item discrimination, and internal consistency. Moreover, we demonstrate that the majority of student responses to the new version are internally consistent even when they are incorrect and provide an example of how the new format can be used to gain insight into student difficulties with specific content in electrostatics.

Differences between diploma and baccalaureate dental hygiene education in British Columbia: a qualitative perspective.

Sunell, S; McFarlane, Rdd; Biggar, H C

2017-08-01

The British Columbia Ministry of Health in Canada approved a new registration category for dental hygienists in 2012. This category included four abilities that registrants were required to demonstrate at a 4th-year baccalaureate degree level. To identify the differences, if any, between diploma and bachelor's degree education with regard to the 4 legislated abilities focused on the process of care for clients with complex needs and/or disabling conditions including client safety, referrals and interprofessional collaboration. Registrants who had entered practice with a diploma and then gained a baccalaureate degree were invited to participate in an online survey including closed- and open-ended questions. The study was a mixed-method design where the qualitative data were nested concurrently in the open-ended questions; the data were analysed through thematic analysis using grounded theory methods. Respondents (n = 123; 51%) indicated their client care had improved with baccalaureate education due to increased knowledge, increased understanding and increased abilities to make judgements with a particular emphasis on evidence-based decisions. These more advanced abilities provided them with increased confidence for taking action particularly in interprofessional contexts and increased the quality of their decision-making thus leading to better care for clients. Respondents described their dental hygiene services as generally being of a higher standard and specifically in the 4 legislated abilities as a direct result of baccalaureate education. © 2016 John Wiley & Sons A/S.

2018-02-01

The study aim was to identify the perceived perspectives of baccalaureate nursing students toward the peer tutoring in the simulation laboratory. Insight into the nursing students' experiences and baseline data related to their perception of peer tutoring will assist to improve nursing education. Q methodology was applied to explore the students' perspectives of peer tutoring in the simulation laboratory. A convenience P-sample of 40 baccalaureate nursing students was used. Fifty-eight selected Q statements from each participant were classified into the shape of a normal distribution using an 11-point bipolar scale form with a range from -5 to +5. PQ Method software analyzed the collected data. Three discrete factors emerged: Factor I ("Facilitate or empower" knowledge acquisition), Factor II ("Safety Net" Support environment), and Factor III ("Mentoring" learn how to learn). The findings of this study support and indicate that peer tutoring is an effective supplementary strategy to promote baccalaureate students' knowledge acquisition, establishing a supportive safety net and facilitating their abilities to learn in the simulation laboratory.

Gazza, Elizabeth A; Shellenbarger, Teresa

2010-01-01

Hiring part-time nursing faculty may impact students, faculty careers, and the institution. Yet, little has been studied, particularly in nursing, regarding the experiences of these faculty. This hermeneutic phenomenological study seeks to understand the lived experience of being a part-time faculty member in a baccalaureate nursing program. Through purposive and snowball sampling, nine nursing faculty in part-time positions in northeastern baccalaureate nursing programs participated in in-depth personal interviews. Four themes were uncovered during data analysis, including achieving the dream, a group divided, for the love of the students, and jump in and figure it out. Results of the study seem to indicate that the experience of being a part-time faculty differs in several ways from being a full-time faculty. Understanding part-time faculty experiences provides insight into faculty needs, issues, and concerns while facilitating the development of research-based recruitment and retention strategies. Recommendations for those involved in nursing education, including nursing faculty and administrators, are provided. Copyright © 2010 Elsevier Inc. All rights reserved.

Liu, Jing-Ying; Liu, Yan-Hui; Yang, Ji-Peng

2014-01-01

The aim of this study was to explore the relationships among study engagement, learning adaptability, and time management disposition in a sample of Chinese baccalaureate nursing students. A convenient sample of 467 baccalaureate nursing students was surveyed in two universities in Tianjin, China. Students completed a questionnaire that included their demographic information, Chinese Utrecht Work Engagement Scale-Student Questionnaire, Learning Adaptability Scale, and Adolescence Time Management Disposition Scale. One-way analysis of variance tests were used to assess the relationship between certain characteristics of baccalaureate nursing students. Pearson correlation was performed to test the correlation among study engagement, learning adaptability, and time management disposition. Hierarchical linear regression analyses were performed to explore the mediating role of time management disposition. The results revealed that study engagement (F = 7.20, P < .01) and learning adaptability (F = 4.41, P < .01) differed across grade groups. Learning adaptability (r = 0.382, P < .01) and time management disposition (r = 0.741, P < .01) were positively related with study engagement. Time management disposition had a partially mediating effect on the relationship between study engagement and learning adaptability. The findings implicate that educators should not only promote interventions to increase engagement of baccalaureate nursing students but also focus on development, investment in adaptability, and time management.

To understand perceptions of faculty and students about attendance policies in baccalaureate nursing programs. Classroom attendance is an issue of debate across academic disciplines. A mixed-methods study was conducted using qualitative data from a stratified random sample of 65 accredited baccalaureate nursing programs; 591 students and 91 faculty from 19 schools responded. Sixty-two percent of faculty thought students who missed class exhibited unprofessional behavior; 69 percent believed students who missed class were less successful in the clinical setting. Students (57 percent) and faculty (66 percent) believed there should be an attendance policy. Twenty-nine students reported needing a break in workload (16.8 percent) or did not find class time valuable (11.8 percent). Variability exists in student and faculty beliefs regarding attendance policies. Understanding these viewpoints and utilizing creative teaching approaches will facilitate learning and create an environment of teamwork and mutual respect.

Johnston, Sandra; Fox, Amanda; Coyer, Fiona Maree

2018-06-01

Transition of nursing student to new graduate depends on successful completion of clinical work placement during an undergraduate course. Supporting students during the clinical placement is imperative. This study examined associations between grade point average, domestic or international status, course entry qualification, and single or dual nursing degree to successful completion of clinical placement. A retrospective audit of 665 students in a baccalaureate nursing program was conducted to examine factors influencing clinical performance of baccalaureate nursing students. A significant association between entry qualification, lower grade point average, international status, and receipt of a constructive note was found: χ 2 = 8.678, df = 3, p = .034, t(3.862), df = 663, p ⩽ .001, and Fisher's exact test = 8.581, df = 1, p = .003, respectively. Understanding factors that affect clinical performance may help early identification of students at risk and allow for supportive intervention during placement and subsequent program completion.

Zhang, Huan; Lambert, Vickie

2008-09-01

Although considerable information exists regarding the learning styles and critical thinking dispositions of nursing students from Western countries, limited comparable information exists within China. The purposes of this study were to assess the learning styles and critical thinking dispositions of Chinese baccalaureate nursing students and to identify the relationships among the learning styles, critical thinking dispositions, and demographics. The sample consisted of 100 Chinese baccalaureate nursing students enrolled at two universities. The data were obtained through a Demographic Data Questionnaire, the California Critical Thinking Disposition Inventory, and the Index of Learning Styles. The primary learning style dimensions were found to be reflective, sensing, visual, and global, while the critically thinking abilities was found to be weak. A number of positive and negative correlations were found among the demographics, learning styles, and critical thinking dispositions. These findings suggest further examination on how to increase nursing students' critical thinking skills based upon their preferred learning styles.

We studied the comprehension abilities of healthy participants with a French version of the Chapman-Cook Speed of Reading Test. The objective was to assess the effect of gender, age and educational level on chronometric performances and errors. In this test, the task is to cross out an inappropriate word within short passages. In the original version, the participant is told to perform as quickly as possible during 150 seconds. The score is usually the number of passages correctly completed within this time limit. In the present study, we measured the time to achieve the first 10 passages, the first 14 passages corresponding to the first page and the total (29 passages) corresponding to the two pages. The number of errors was also considered. The normative sample included 150 participants (63 males; 87 females) with three educational level (47: superior to baccalaureate; 21: baccalaureate and 78: inferior to baccalaureate). Age was between 20 and 69 years old, divided in 5 age groups, without neurological or psychiatric disease, or cognitive abnormal development. All were French native speaking and have been schooling in France. For time completion, no effect of gender was found, but a significant and unexpected effect of age was shown according to educational level. Whereas the age groups obtained similar times for educational levels superior to baccalaureate, an age effect was demonstrated for the educational level inferior to baccalaureate. Participants over 40 years of age were faster than younger participants with the same educational level and similar than all age groups of higher educational level. On the contrary, young participants were slower compared to those with high educational levels and all older participants without baccalaureate. This surprising result is discussed.

2009-01-01

This descriptive and multivariate correlational study identifies work-related situations that were perceived as stressful in a sample of part-time clinical affiliate nursing faculty (n = 91) from a western state who teach in baccalaureate programs. The most stressful conditions include being physically and emotionally drained; working outside regular hours; dealing with the number of role expectations; and receiving inadequate monetary compensation. Subjects reported other specific stressful situations related to their work with clinical agencies, universities, and students. The researcher also examined the relationships between selected background factors (number of years of clinical teaching experience, clinical teacher education, and holding a second job), role stress, and job satisfaction. Even though this sample had a high job satisfaction rating, the variable, role stress, was shown to significantly predict job satisfaction. Lastly, implications for nurse educators in baccalaureate programs are explored.

The Impact of Baccalaureate Medical Humanities on Subsequent Medical Training and Practice: A Physician-Educator's Perspective.

Science.gov (United States)

Barron, Lauren

2017-12-01

This reflective essay is an attempt to organize trends in feedback I have observed during ten years of coursework, conversations, and correspondence with former students associated with the Medical Humanities Program at Baylor University. Over the years, recurrent themes arise when speaking with alumni about whether and how their medical humanities experience intersects with their current training. I have identified five particular domains in which baccalaureate medical humanities training affects students' subsequent healthcare professions training and practice: context and complementarity, clinical relevance, reflective practice, professional preparedness and vocational calling. I created an instrument of open-ended questions for each of these categories and posted it to social media with an invitation for alumni to respond. This informal survey was conceived as an exploratory exercise with the intent to help generate a foundation for more formal qualitative research in these five domains. In this essay, I offer my own reflections together with those of former students on the impact of baccalaureate-level medical humanities training in order to illustrate the benefits in each domain for subsequent healthcare training and practice. The need for qualitative research that explores the impact of baccalaureate medical humanities merits collaboration between multiple centers of investigation across many disciplines, and across the divide between premedical and medical educators.

2016-01-01

The need for greater involvement of the nursing profession in cost containment efforts has been documented extensively. More thorough education of nurses in the subject of health economics (HE) is one of the factors that could contribute toward achievement of that goal. The project's main contribution is the development of the unique list of essential HE competencies for baccalaureate nursing students. The proposed competencies were developed and validated using the protocol by Lynn (1986) for two-stage content validation of psychometric instruments. An additional validation step that included a nationwide survey of nurse administrators was conducted to measure the value they place on the health economics-related skills and knowledge of their employees. A set of six HE competencies was developed. Their validity was unanimously approved by the panel of five experts and additionally supported by the survey results (with individual competencies' approval rates of 67% or higher). The incorporation of economic thinking into the nationwide standards of baccalaureate nursing education, and professional nursing competencies, will enhance the capacity of the nursing workforce to lead essential change in the delivery of high-value affordable health care nationwide.

Escolar-Chua, Rowena L

2018-06-01

Moral distress, moral sensitivity, and moral courage among healthcare professionals have been explored considerably in recent years. However, there is a paucity of studies exploring these topics among baccalaureate nursing students. The purpose of this study was to explore the relationship between and among moral distress, moral sensitivity, and moral courage of undergraduate baccalaureate nursing students. The research employed a descriptive-correlational design to explore the relationships between and among moral distress, moral sensitivity, and moral courage of undergraduate nursing students. Participants and research context: A total of 293 baccalaureate Filipino nursing students who have been exposed to various clinical areas participated in the study. Ethical considerations: Institutional review board approval was sought prior to the conduct of the study. Self-determination was assured and anonymity and confidentiality were guaranteed to all participants. Results indicate that a majority of the nursing students in the clinical areas encounter morally distressing situations that compromise quality patient care. However, despite the fact that they want to do what is in the best interest of their patients, their perception of being the inexperienced among the healthcare team drives the majority of them to ignore morally distressing situations to avoid conflict and confrontation. Another interesting finding is that 79.20% of the respondents hardly consider quitting the nursing profession even if they frequently encounter morally distressing situations. Analysis also shows associations between moral distress intensity and frequency ( r = 0.13, p < 0.05) and moral distress intensity and moral sensitivity ( r = 0.25, p < 0.05). The dimensions of moral courage are also related to both moral distress and moral sensitivity. Results of the study imply that moral distress is a reality among all healthcare professionals including nursing students and requires more

Nursing students are valuable human resources. Detection of potential depression among nursing students is crucial since depression can lead to low productivity, minimized quality of life, and suicidal ideas. Identifying factors affecting depression among students can help nursing educators to find ways to decrease depression. The purpose of this study was to examine rates of depression and the associations between depression and stress, emotional support, and self-esteem among baccalaureate nursing students in Thailand. This correlational, cross-sectional study recruited 331 baccalaureate Thai nursing students. Students completed three instruments that had been translated into Thai: The Center for Epidemiology Studies Depression Scale, Perceived Stress Questionnaire, and Rosenberg Self-Esteem Scale. Another instrument created in Thai was used to measure emotional support. Results revealed that, when using the standard definition, 50.1% of the students were depressed. Stress was positively related to depression, whereas emotional support and self-esteem were negatively related to depression.

Full Text Available OBJECTIVE: The purpose of this study was to evaluate the morphological changes of upper airway after Twin Block (TB treatment in growing patients with Class II division 1 malocclusion and mandibular retrusion compared with untreated Class II patients by cone beam computed tomography (CBCT. MATERIALS AND METHODS: Thirty growing patients who have completed TB treatment were recruited into TB group. The control group (n = 30 was selected from the patients with the same diagnosis and without TB treatment. CBCT scans of the pre-treatment (T1 and post-treatment (T2 data of TB group and control data were collected. After three-dimensional (3D reconstruction and registration of T1 and T2 data, the morphological changes of upper airway during TB treatment were measured. The statistical differences between T1 and T2 data of TB group as well as T2 and control data were accessed by t-test. RESULTS: During the TB treatment, the mandible moved advanced by 3.52 ± 2.14 mm in the horizontal direction and 3.77 ± 2.10 mm in the vertical direction. The hyoid bone was in a more forward and inferior place. The upper airway showed a significant enlargement in nasopharynx, oropharynx and hypopharynx. In addition, the nasopharynx turned more circular, and the oropharynx became more elliptic in transverse shape. However, the transverse shape of the hypopharynx showed no significant difference. After comparison between T2 and control data, only the horizontal movement of the hyoid bone, the volumetric expansion of the oropharynx and hypopharynx, and changes of the oropharyngeal transverse shape showed significant difference. CONCLUSION: Compared to the untreated Class II patients, the upper airway of growing patients with Class II division 1 malocclusion and mandibular retrusion showed a significant enlargement in the oropharynx and hypopharynx as well as a more elliptic transverse shape in the oropharynx, and the hyoid bone moved to an anterior position after TB

This study presents the results of a survey of academic institutions offering nuclear-related training and education at the less than baccalaureate degree level. The scope of the survey includes only those programs which have a nuclear power industry application, and excludes all programs which are affiliated with nuclear medicine. The survey instrument was distributed by the Institute of Nuclear Power Operations to 262 academic institutions. The survey universe was compiled from a number of publications that listed nuclear-related academic programs. Since the initial mailing in May 1981, ten of the institutions have been determined to no longer exist and eight other listings have been identified as duplications, thus reducing the universe to 244 institutions. Fifty-five percent of the survey population (134 institutions) responded to the questionnaire, of which 45 percent (109) were out of the survey scope and 10 percent (25) indicated they offered less than baccalaureate degree, nuclear-related programs

2013-08-15

Purpose: The aim of this study was to describe the CT findings of a displaced left upper division bronchus (DLUDB) in adults. Materials and methods: Ten patients with DLUDB were identified. The following CT features were assessed: origin of the DLUDB; distance between the origin of the DLUDB and the origin of the left upper lobe (LUL) bronchus; height of the origin of the DLUDB against the left pulmonary artery (LPA); difference of the main bronchial length; ventilated segment; course of the left pulmonary artery against the DLUDB; and presence of an accessory fissure or other anomalies. Results: DLUDB arose from the posterolateral or lateral aspect of the left main bronchus immediately proximal to the origin of the LUL bronchus. It tended to course along the posterior wall of the LPA and to ventilate the apicoposterior segment with or without the anterior segment. The LPA passed between the displaced bronchus and the lingular bronchus. The origin of the DLUDB was located lower than the inferior wall of the proximal LPA in 6 patients. The accessory fissure between the associated segment and remaining part of the LUL and right tracheal bronchus coexisted in 7 and 3 patients respectively. Conclusion: DLUDB has characteristic findings on CT. Radiologists should be aware of this entity and inform the surgeon as it can prevent serious complications in a patient who may undergo lobectomy of the left lung.

2015-08-01

The literature describing successful pedagogies for teaching ostomy care to baccalaureate nursing students is limited. This qualitative study investigated the potential benefits of participating in an immersive simulation that allowed baccalaureate nursing students to explore the physical and psychosocial impact of ostomy surgery. Junior-level nursing students attended a 2-hour interactive session during which they learned about preoperative stoma site marking and practiced the maneuvers on a peer. Students then wore an ostomy appliance for the next 24 hours, completed tasks simulating ostomy self-care, and submitted a three- to four-page reflection on the experience. These data were coded using the iterative process of constant comparison described by Glaser. Six major themes were identified: Accommodation for Activities of Daily Living, Coping with Annoyances, Body Image and Feelings, Disclosure, Insights for Teaching, and Empathy. Each participant affirmed the value of the experience. Suggestions for future research studies are discussed. Copyright 2015, SLACK Incorporated.

Coupled multiple-response versus free-response conceptual assessment: An example from upper-division physics

Directory of Open Access Journals (Sweden)

Bethany R. Wilcox

2014-10-01

Full Text Available Free-response research-based assessments, like the Colorado Upper-division Electrostatics Diagnostic (CUE, provide rich, fine-grained information about students’ reasoning. However, because of the difficulties inherent in scoring these assessments, the majority of the large-scale conceptual assessments in physics are multiple choice. To increase the scalability and usability of the CUE, we set out to create a new version of the assessment that preserves the insights afforded by a free-response format while exploiting the logistical advantages of a multiple-choice assessment. We used our extensive database of responses to the free-response CUE to construct distractors for a new version where students can select multiple responses and receive partial credit based on the accuracy and consistency of their selections. Here, we describe the development of this modified CUE format, which we call coupled multiple response (CMR, and present data from direct comparisons of both versions. We find that the two formats have the same average score and perform similarly on multiple measures of validity and reliability, suggesting that the new version is a potentially viable alternative to the original CUE for the purpose of large-scale research-based assessment. We also compare the details of student responses on each of the two versions. While the CMR version does not capture the full scope of potential student responses, nearly three-quarters of our students’ responses to the free-response version contained one or more elements that matched options provided on the CMR version.

Pain affects approximately 76 million adults in the US. Though pain management has been targeted as a top priority, it continues to be inadequately addressed. Nursing faculty are in a unique position to significantly address the problem through facilitating the acquisition and utilization of knowledge by student nurses. The purpose of this study was to determine the knowledge of and attitudes toward pain in baccalaureate nursing students and faculty to establish a foundation for a systematic and comprehensive integration of pain content in the curricula. The descriptive design included a sample of 162 junior and senior students enrolled in a baccalaureate nursing program in Texas and 16 nursing faculty. The Knowledge and Attitudes Survey Regarding Pain (KASRP) was used to measure knowledge and attitudes toward pain. A direct correlation was found between the level of education and the percentage correct score. Differences found in knowledge and attitudes among the three levels of students and faculty were significant (df = 3.173; F = 14.07, p pain through case scenarios of a patient who was smiling and talking as compared to a patient who was lying quietly and grimacing (X2 = 37.13, p pain assessment and treatment are taught is indicated. Further studies are needed to assess changes in knowledge and attitudes toward pain as curricular revisions are made. Copyright © 2013 American Society for Pain Management Nursing.

The artery blood supply variant of the upper limb

Science.gov (United States)

MASLARSKI, IVAN

2015-01-01

Variations of arterial patterns in the upper limb have represented the most common subject of vascular anatomy. Different types of artery branching pattern of the upper limb are very important for orthopedists in angiographic and microvascular surgical practice. The brachial artery (BA) is the most important vessel in the normal vascular anatomy of the upper limb. The classical pattern of the palmar hand region distribution shows the superficial palmar arch. Normally this arch is formed by the superficial branch of the ulnar artery and completed on the lateral side by one of these arteries: the superficial palmar branch of the radial artery, the princeps pollicis artery, the superficial palmar branch of the radial artery or the median artery. After the routine dissection of the right upper limb of an adult male cadaver, we found a very rare variant of the superficial arch artery – a division in a higher level brachial artery. We found this division at 10.4 cm from the beginning of the brachial artery. This superficial brachial artery became a radial artery and was not involved in the formation of the palm arch. In the forearm region, the artery variant was present with the median artery and the ulnar artery, which form the superficial palm arch. PMID:26733754

Couch, Brian A; Wood, William B; Knight, Jennifer K

2015-03-02

Measuring students' conceptual understandings has become increasingly important to biology faculty members involved in evaluating and improving departmental programs. We developed the Molecular Biology Capstone Assessment (MBCA) to gauge comprehension of fundamental concepts in molecular and cell biology and the ability to apply these concepts in novel scenarios. Targeted at graduating students, the MBCA consists of 18 multiple-true/false (T/F) questions. Each question consists of a narrative stem followed by four T/F statements, which allows a more detailed assessment of student understanding than the traditional multiple-choice format. Questions were iteratively developed with extensive faculty and student feedback, including validation through faculty reviews and response validation through student interviews. The final assessment was taken online by 504 students in upper-division courses at seven institutions. Data from this administration indicate that the MBCA has acceptable levels of internal reliability (α=0.80) and test-retest stability (r=0.93). Students achieved a wide range of scores with a 67% overall average. Performance results suggest that students have an incomplete understanding of many molecular biology concepts and continue to hold incorrect conceptions previously documented among introductory-level students. By pinpointing areas of conceptual difficulty, the MBCA can provide faculty members with guidance for improving undergraduate biology programs. © 2015 B. A. Couch et al.

The objective of the project were: (1) to conduct a needs assessment utilizing the concepts of marketing in health planning, and (2) to identify health needs of a community based on active participation by members of the community. Through a collaborative effort with a community health agency, students were able to integrate the principles of marketing and participative decision-making into a learning experience. The results of the needs assessment provided the agency with valuable information for strategic planning.

Phase division multiplexed EIT for enhanced temporal resolution.

Science.gov (United States)

Dowrick, T; Holder, D

2018-03-29

The most commonly used EIT paradigm (time division multiplexing) limits the temporal resolution of impedance images due to the need to switch between injection electrodes. Advances have previously been made using frequency division multiplexing (FDM) to increase temporal resolution, but in cases where a fixed range of frequencies is available, such as imaging fast neural activity, an upper limit is placed on the total number of simultaneous injections. The use of phase division multiplexing (PDM) where multiple out of phase signals can be injected at each frequency is investigated to increase temporal resolution. TDM, FDM and PDM were compared in head tank experiments, to compare transfer impedance measurements and spatial resolution between the three techniques. A resistor phantom paradigm was established to investigate the imaging of one-off impedance changes, of magnitude 1% and with durations as low as 500 µs (similar to those seen in nerve bundles), using both PDM and TDM approaches. In head tank experiments, a strong correlation (r  >  0.85 and p  EIT injections.

PROJECTING PRINCIPLES OF «MATHEMATICAL AND PHYSICAL BASICS IN INFORMATICS» MODULE AS PART OF A UNIVERSAL BACCALAUREATE PROGRAM

Directory of Open Access Journals (Sweden)

E. K. Samerkhanova

2016-01-01

Full Text Available This article is a presentation of “Mathematical and Physical Basics in Informatics” Module projected as part of universal baccalaureate model realized in Minin State Pedagogical University, Nizhny Novgorod, within the educational program for an extended group of qualifications “Informatics and Calculating Machines”. Module authors defined a strategy for baccalaureates preparation in the field of informational technology, which is realized due to a bunch of principles: education fundamentalization, learning systematization, activity, integration and student-centration. The principle of education fundamentalization requires consolidation of scientific and methodological preparation of students. The principle of learning systematization guarantees formation of students’ holistic ideology. The principle of integration is directed onto qualitative interdisciplinary conversion based on mutual enrichment of knowledge and skills. The principle of activity considers student personality, its formation and growth with respect to practical activity as a special form of psychical activity. The principle of student-centration is displayed as social-humanistic purpose of the educational process.

Given the increasing incidence of adverse events and medication errors in healthcare settings, a greater emphasis is being placed on the integration of patient safety competencies into health professional education. Nurses play an important role in preventing and minimizing harm in the healthcare setting. Although patient safety concepts are generally incorporated within many undergraduate nursing programs, the level of students' confidence in learning about patient safety remains unclear. Self-reported patient safety competence has been operationalized as confidence in learning about various dimensions of patient safety. The present study explores nursing students' self-reported confidence in learning about patient safety during their undergraduate baccalaureate nursing program. Cross-sectional study with a nested cohort component conducted annually from 2010 to 2013. Participants were recruited from one Canadian university with a four-year baccalaureate of nursing science program. All students enrolled in the program were eligible to participate. The Health Professional Education in Patient Safety Survey was administered annually. The Health Professional Education in Patient Safety Survey captures how the six dimensions of the Canadian Patient Safety Institute Safety Competencies Framework and broader patient safety issues are addressed in health professional education, as well as respondents' self-reported comfort in speaking up about patient safety issues. In general, nursing students were relatively confident in what they were learning about the clinical dimensions of patient safety, but they were less confident about the sociocultural aspects of patient safety. Confidence in what they were learning in the clinical setting about working in teams, managing adverse events and responding to adverse events declined in upper years. The majority of students did not feel comfortable speaking up about patient safety issues. The nested cohort analysis confirmed these

2012-01-01

Appropriate and effective critical thinking and problem solving is necessary for all nurses in order to make complex decisions that improve patient outcomes, safety, and quality of nursing care. With the current emphasis on quality improvement, critical thinking ability is a noteworthy concern within the nursing profession. An in-depth review of literature related to critical thinking was performed. The use of nursing care plans and concept mapping to improve critical thinking skills was among the recommendations identified. This study compares the use of nursing care plans and concept mapping as a teaching strategy for the enhancement of critical thinking skills in baccalaureate level nursing students. The California Critical Thinking Skills Test was used as a method of comparison and evaluation. Results indicate that concept mapping enhances critical thinking skills in baccalaureate nursing students.

Stressors, academic performance, and learned resourcefulness in baccalaureate nursing students.

Science.gov (United States)

Goff, Anne-Marie

2011-01-01

High stress levels in nursing students may affect memory, concentration, and problem-solving ability, and may lead to decreased learning, coping, academic performance, and retention. College students with higher levels of learned resourcefulness develop greater self-confidence, motivation, and academic persistence, and are less likely to become anxious, depressed, and frustrated, but no studies specifically involve nursing students. This explanatory correlational study used Gadzella's Student-life Stress Inventory (SSI) and Rosenbaum's Self Control Scale (SCS) to explore learned resourcefulness, stressors, and academic performance in 53 baccalaureate nursing students. High levels of personal and academic stressors were evident, but not significant predictors of academic performance (p = .90). Age was a significant predictor of academic performance (p = learned resourcefulness scores than females and Caucasians. Studies in larger, more diverse samples are necessary to validate these findings.

Stanley, Jacob T.; Su, Weifeng; Lewandowski, H. J.

2017-12-01

We demonstrate how students' use of modeling can be examined and assessed using student notebooks collected from an upper-division electronics lab course. The use of models is a ubiquitous practice in undergraduate physics education, but the process of constructing, testing, and refining these models is much less common. We focus our attention on a lab course that has been transformed to engage students in this modeling process during lab activities. The design of the lab activities was guided by a framework that captures the different components of model-based reasoning, called the Modeling Framework for Experimental Physics. We demonstrate how this framework can be used to assess students' written work and to identify how students' model-based reasoning differed from activity to activity. Broadly speaking, we were able to identify the different steps of students' model-based reasoning and assess the completeness of their reasoning. Varying degrees of scaffolding present across the activities had an impact on how thoroughly students would engage in the full modeling process, with more scaffolded activities resulting in more thorough engagement with the process. Finally, we identified that the step in the process with which students had the most difficulty was the comparison between their interpreted data and their model prediction. Students did not use sufficiently sophisticated criteria in evaluating such comparisons, which had the effect of halting the modeling process. This may indicate that in order to engage students further in using model-based reasoning during lab activities, the instructor needs to provide further scaffolding for how students make these types of experimental comparisons. This is an important design consideration for other such courses attempting to incorporate modeling as a learning goal.

2014-03-04

The need to provide humanistic care in the contemporary healthcare system is more imperative now and the importance of cultivating caring in nursing education is urgent. Caring as the primary work of nursing has been discussed extensively, such as the meaning of caring, and teaching and learning strategies to improve nursing students' caring ability. Yet attempts to understand students' perspectives on learning about caring and to know their learning needs are seldom presented. The aim of this qualitative descriptive study was to explore the baccalaureate nursing students' perspectives on learning about caring in China. A qualitative descriptive study using focus group interviews were undertaken in two colleges in Yunnan Province, China from February 2010 to April 2010. Purposeful sampling of 20 baccalaureate nursing students were recruited. Content analysis of the transcribed data was adopted to identify the themes. Four categories with some sub-categories related to students' perspectives on learning about caring were identified from the data: 1) Learning caring by role model; 2) conducive learning environment as the incentive to the learning about caring; 3) lack of directive substantive way of learning as the hindrance to the learning about caring; 4) lack of cultural competency as the barrier to the learning about caring. Both caring and uncaring experiences can promote the learning about caring in a way of reflective practice. The formal, informal and hidden curricula play an important role in the learning about caring. Cultural awareness, sensitivity and humility are important in the process of learning to care in a multicultural area.

Developing skills for youth in the 21st century: The role of elite International Baccalaureate Diploma Programme schools in China

Science.gov (United States)

Wright, Ewan; Lee, Moosung

2014-04-01

There is a growing body of research suggesting that schools need to respond to changing social and economic dynamics by prioritising "21st-century skills". Proponents of this view, who have been termed "the 21st century skills movement", have called for greater emphasis on cognitive and non-cognitive skills development, alongside the learning of subject content and technical skills. This paper explores the potential of International Baccalaureate Diploma Programme (IBDP) schools to respond to this mandate in China, one of the fastest-growing markets for International Baccalaureate® (IB) schools globally. The authors' research team undertook a multi-site case study of five elite IBDP schools in China. Their findings revealed confidence among interviewees that the IB educational philosophy was conducive to 21st-century skills development, especially through the provision of the three IBDP "Core Requirements", which are Creativity, Action, Service (CAS), Extended Essay (EE) and Theory of Knowledge (TOK). Despite this confidence, concerns remain about the implementation of the IB educational philosophy in the context of IBDP schools in China.

For this, it should firstly be assessment personal values of nursing students. The purpose of the study was to determine the personal values of nursing students with respect to certain variables. The population of the study, which had a cross-sectional design, included all undergraduate students (n = 525) attending the nursing school. The sample group comprised 397 nursing students selected from among the nursing students attending a baccalaureate programme in Turkey using the disproportional cluster sampling method. Data were collected utilizing the Personal Information Form and Value Preferences Scale. The personal values of the students were found to be moral, social, financial/economic, aesthetic, political, religious and scientific/theoretical values. The study suggested that the age, year at school and economic level of the family affected the students' values. Values influence behaviours that are an essential component of humanistic nursing care. They are integral to professional socialization, evident in nursing care and fundamental decisions that affect practice. © 2012 Wiley Publishing Asia Pty Ltd.

Professional identity and competent ethical behaviors of nursing students are commonly developed through curricular inclusion of professional nursing values education. Despite the enactment of this approach, nursing students continue to express difficulty in managing ethical conflicts encountered in their practice. This descriptive correlational study explores the relationships between professional nursing values, self-esteem, and ethical decision making among senior baccalaureate nursing students. A convenience sample of 47 senior nursing students from the United States were surveyed for their level of internalized professional nursing values (Revised Professional Nursing Values Scale), level of self-esteem (Rosenberg's Self-Esteem Scale), and perceived level of confidence in ethical decision making. A significant positive relationship (p self-esteem. The results of this study can be useful to nursing educators whose efforts are focused on promoting professional identity development and competent ethical behaviors of future nurses.

This paper reports an investigation into the critical thinking disposition of students enrolled in a baccalaureate nursing programme at a university in Korea. Critical thinking may be summarized as a skilled process that conceptualizes and applies information from observation, experience, reflection, inference and communication in a technical manner. It is more of a rational act used as an instrument rather than as a result. Critical thinking is a core competency in nursing and has been widely discussed in nursing education. However, the results of previous research on the effectiveness of nursing education in improving students' critical thinking have been inconsistent. A longitudinal design was used with a convenience sample of 60 nursing students; 32 students participated four times in completing a questionnaire each March from 1999 to 2002. The California Critical Thinking Disposition Inventory was administered to measure disposition to critical thinking. There was a statistically significant improvement in critical thinking disposition score by academic year (F = 7.54, P = 0.0001). Among the subscales, open-mindedness, self-confidence, and maturity also showed a statistically significant difference by academic year (P = 0.0194, 0.0041, 0.0044). Teaching strategies to enhance critical thinking should be developed, in addition to further research on the effect of the nursing curriculum on students' critical thinking. Moreover, survey instruments could be adjusted to incorporate characteristics of the Korean culture.

Full Text Available Purpose: This study aimed to evaluate the program outcome in nursing baccalaureate in Korea. The analysis based on course embedded assessment. The concrete objectives were establishment of program outcome assessment, confirmation of student competency through weighting of program outcomes, and using the results of the evaluation in the circular feedback process in a nursing school in Korea. Methods: This study was conducted with a nursing education curriculum in a Korean nursing school. Data were collected through 28 students’ program outcome measurement from January 2013 to December 2014. Data were analyzed using a pairwise comparison method and analytic hierarchy process. Results: There were 1 to 3 direct and indirect assessment tools and for each program outcomes and each tool had measurable rubrics. There were 1 to 3 direct assessment tools for each program outcome, and each tool had measurable rubrics. This model derived rank of program outcomes from "care integration" to "global perception" through weight calculation. All direct assessment results were over 70%. The indirect assessment results were over the cutoff except for program outcomes 4 and 7. Conclusion: Each step of course embedded assessment was adaptive in nursing program outcome measure. The achievement of learning outcome provided reasonable tools for faculty and students.

Predicting students' aptitude for post-secondary success remains a widely studied topic. This descriptive study explored demographic variables contributing to success in quantitative courses required by the nursing degree plan. Identification of an "at risk" student profile may inform interventions with which to support attainment of an academic degree. The purpose of this study was to examine the associations between demographic characteristics and successful completion of baccalaureate nursing courses thought to enhance quantitative reasoning skills: first-year math, first-year chemistry, and second-year pathopharmacology nursing. This retrospective analysis accessed 4521 academic records of students who took these three courses at a United States university sometime between Fall 2008 and Fall 2015. De-identified student data included course grades, gender, full-time study, income, marital status, first generation, secondary school (also known as high school) location, dual credit, and high school and university grade point averages. Descriptive statistical analysis was conducted to describe the important features of the data. Of the 4521 records, 2556 undergraduates (57%) passed the courses in which they were enrolled. Among successful students, females outnumbered males (66%), ages ranged from 20 to 24 years, 86% were classified as low income, 54% fit the designation of first generation, and 12% earned dual credit (university credit during secondary school). Our data demonstrate a positive relationship between dual credit and success, with the strongest correlation (0.62) noted for students in pathopharmacology. In the baccalaureate-nursing plan of study, courses thought to enhance students' quantitative reasoning skills remain difficult for some to successfully complete. We conclude that the more successful students tend to be older, have a higher income, and a higher high school grade point average, while those less successful are directly out of high

Development of Instructional Competencies for Assessing and Managing Suicide Risk for Baccalaureate Nursing Education: A Modified Delphi Study.

Kotowski, Abigail; Roye, Carol

2017-03-01

Suicide is a major health problem and a leading cause of death throughout the world. A primary goal for suicide prevention is reforming health professional education in order to increase the competence of health professionals in assessing and managing suicide risk. Nursing leadership is involved in this reform, yet nurses frequently lack the competence to care for patients in suicidal crisis. An identified gap in baccalaureate nursing education is instructional competencies for assessing and managing suicide risk. A modified Delphi study was used. The study began with a focus group which was conducted in order to develop the Round I Survey which included forty-four competencies. After scoring these competencies, thirty-four were scored for inclusion, two were dropped and eight were revised according to panel members' comments. The Round II Survey comprised the eight revised competencies which were scored for inclusion, resulting in forty-two competencies in the final set of instructional competencies. Forty-two instructional competencies were developed: fourteen pre-assessment instructional competencies, fifteen assessment instructional competencies, and thirteen management instructional competencies. Incorporating these instructional competencies into baccalaureate nursing education might increase the competence of nursing students, and thus new nurses, in caring for patients at risk for suicide. These instructional competencies provide a first step to address the challenging task of intervening with patients at risk for suicide.

2010-01-01

The objectives of this study were: 1) to evaluate the associations between an increased overjet (IO) and other dentoskeletal characteristics of Class II division 1 malocclusions in the mixed dentition; 2) to assess whether Class II division 1 malocclusions or rather an increased overjet per se is a risk factor for upper incisor trauma (UIT). A sample of 900 mixed dentition subjects, was observed by clinical inspection, analysis of dental casts, and lateral cephalograms. The diagnostic performance of IO (overjet ≥ 7 mm) was evaluated in relation to other Class II dentoskeletal features (Class II molar and canine relationships, and skeletal Class II relationships). Secondly, the diagnostic performance of IO and of the other Class II dentoskeletal components was tested with regard to the prevalence of UIT. Diagnostic performance was assessed by odds ratio and positive likelihood ratio. The diagnostic performance of IO with regard to the other dentoskeletal components of Class II malocclusions was not significant. The only Class II features associated significantly with an increased risk of UIT was IO. When used as an isolated occlusal feature, IO is not a valid diagnostic indicator for Class II division 1 malocclusions. An increased overjet per se, and not Class II malocclusions, appears to be a significant risk factor for UIT. These findings recommend discrimination between clinical conditions showing an isolated IO from comprehensive Class II malocclusions during diagnosis, analysis of treatment outcomes, and evaluation of the risk of upper incisor trauma.

Newton, Sarah E; Moore, Gary

2013-01-01

The purpose of this study was to describe the critical thinking (CT) skills of basic baccalaureate (basic-BSN) and accelerated second-degree (ASD) nursing students at nursing program entry. Many authors propose that CT in nursing should be viewed as a developmental process that increases as students' experiences with it change. However, there is a dearth of literature that describes basic-BSN and ASD students' CT skills from an evolutionary perspective. The study design was exploratory descriptive. The results indicated thatASD students had higher CT scores on a quantitative critical thinking assessment at program entry than basic-BSN students. CT data are needed across the nursing curriculum from basic-BSN and ASD students in order for nurse educators to develop cohort-specific pedagogical approaches that facilitate critical thinking in nursing and produce nurses with good CT skills for the future.

Mueller, J.R.

1989-01-01

In the early 1980s, Wisconsin Public Service Corporation (WPSC) made a firm commitment to pursue development and subsequent delivery of an appropriate, academically accredited program leading to a baccalaureate degree in nuclear science for its nuclear operations personnel. Recognizing the formidable tasks to be accomplished, WPSC worked closely with the University of Maryland University College (UMUC) in curriculum definition, specific courseware development for delivery by computer-aided instruction, individual student evaluation, and overall program implementation. Instruction began on our nuclear plant site in the fall of 1984. The university anticipates conferring the first degrees from this program at WPSC in the fall of 1989. There are several notable results that WPSC achieved from this degree program. First and most importantly, an increase in the level of education of our employees. It should be stated that this program has been well received by WPSC operator personnel. These employees, now armed with plant experience, a formal degree in nuclear science, and professional education in management are real candidates for advancement in our nuclear organization

Establishing a strong foundation for the development of clinical reasoning in nursing students is essential to ensure safe and effective patient care. This study explored prelicensure baccalaureate nursing students' perceptions of their development of clinical reasoning, as well as their perceptions of how it is taught. In this phenomenological study, individual semistructured interviews were conducted to gather data related to participants' perceptions of their development of clinical reasoning. Data were analyzed using procedural steps delineated by Giorgi. Data analysis revealed three main themes: Instructor Characteristics, Importance of Clinical Reasoning, and Best Place to Learn Clinical Reasoning. Students recognized how clinical reasoning enhances safe and effective clinical practice and indicated the clinical arena was the most beneficial environment in which to learn clinical reasoning. Understanding students' perceptions of learning benefits nurse educators in planning nursing program curricula to enhance and facilitate the development of clinical reasoning.

Andreou, Christos; Papastavrou, Evridiki; Merkouris, Anastasios

2014-03-01

Critical thinking is a desirable competency for contemporary nurses although there are growing concerns supporting a disturbing paucity in its achievement. Learning styles reflect habitual behaviors which determine distinct preferences within learning situations. Evidence suggests that critical thinking could evolve through learning processes. Variances in critical thinking achievement by nursing students might therefore be influenced by individual learning preferences. The concepts "learning styles" and "critical thinking" have been independently examined in the nursing literature. No reviews were found however exploring their association in nursing education. To identify the potential relationships between learning styles and critical thinking in baccalaureate nursing students. Systematic review. Eleven electronic databases were utilized without geographical and time publishing filters. Hand-searching journals and scanning references from retrieved studies were also performed. Databases were searched for descriptive correlational studies which considered the relationship between learning styles and critical thinking in baccalaureate nursing students. The authors independently progressed three stage screening. Retrieved articles were reviewed at title, abstract and full text levels according to predetermined criteria. All included studies were quality appraised using a rating tool for descriptive studies. Six studies were finally included. Findings were grouped under four key themes: predominant learning styles, critical thinking scoring, critical thinking evolution across academic progress and learning styles-critical thinking correlations. Learning styles' diversities, weak critical thinking and inconsistent evolution through academic progress were revealed across studies. Critical thinking differed significantly between learning styles. Commonly accepted models in nursing education were lacking in both learning styles and critical thinking. Within studies

Computational Fair Division

DEFF Research Database (Denmark)

Fair division is a fundamental problem in economic theory and one of the oldest questions faced through the history of human society. The high level scenario is that of several participants having to divide a collection of resources such that everyone is satisfied with their allocation -- e.g. two...... heirs dividing a car, house, and piece of land inherited. The literature on fair division was developed in the 20th century in mathematics and economics, but computational work on fair division is still sparse. This thesis can be seen as an excursion in computational fair division divided in two parts....... The first part tackles the cake cutting problem, where the cake is a metaphor for a heterogeneous divisible resource such as land, time, mineral deposits, and computer memory.

Thompson, Cheryl W; Bucher, Julia A

2013-01-01

The purpose of this article is to describe how community health competencies for baccalaureate nursing education have been met by locating clinical experiences in nurse-managed wellness centers. Such centers are an ideal setting for students to integrate theoretical concepts into clinical practice while building on previous learning. Students are able to develop skills in community health nursing practice at individual, family, and population level. In addition, the practice setting provides other advantages. Clients who represent a vulnerable population group receive valuable health services. Students gain learning opportunities that are broader than community health competencies, and faculty are provided clinical practice, research, and scholarship opportunities. The challenges to year-round sustainability of nurse-managed centers are burdensome; however, the benefits outweigh the difficulty of those challenges. Copyright © 2013 Elsevier Inc.

Dunagan, Pamela B; Kimble, Laura P; Gunby, Susan Sweat; Andrews, Margaret M

2014-06-01

The purpose of this study was to explore the relationship between attitudes of prejudice and cultural competence among nursing students. Using a mixed-methods design, a convenience sample of students (N = 129) currently enrolled in a baccalaureate nursing program was recruited via Web networking. Data regarding attitudes of prejudice, cultural competence, prior cultural experience, and integration of cultural competence were obtained via a Web-based survey. Multiple linear regression was used to predict cultural knowledge, attitudes, and consciousness. Although all three regression models were statistically significant, the significant predictors varied within each model. Greater prejudice was a significant predictor of less culturally competent attitudes toward providing nursing care. Existing prejudice among nursing students needs to be addressed to help promote positive cultural attitudes and, ultimately, cultural competent nursing care.

to non Gaussian infinitely divisible processes. First we show that the class of infinitely divisible semimartingales is so large that the natural analog of Stricker's theorem fails to hold. Then, as the main result, we prove that an infinitely divisible semimartingale relative to the filtration generated...... by a random measure admits a unique decomposition into an independent increment process and an infinitely divisible process of finite variation. Consequently, the natural analog of Stricker's theorem holds for all strictly representable processes (as defined in this paper). Since Gaussian processes...... are strictly representable due to Hida's multiplicity theorem, the classical Stricker's theorem follows from our result. Another consequence is that the question when an infinitely divisible process is a semimartingale can often be reduced to a path property, when a certain associated infinitely divisible...

Preliminary stratigraphy and facies analysis of the Upper Cretaceous Kaguyak Formation, including a brief summary of newly discovered oil stain, upper Alaska Peninsula

The Alaska Division of Geological and Geophysical Surveys has an ongoing program aimed at evaluating the Mesozoic forearc stratigraphy, structure, and petroleum systems of lower Cook Inlet. Most of our field studies have focused on the Jurassic component of the petroleum system (this report). However, in late July and early August of 2012, we initiated a study of the stratigraphy and reservoir potential of the Upper Cretaceous Kaguyak Formation. The Kaguyak Formation is locally well exposed on the upper Alaska Peninsula (fig. 25) and was named by Keller and Reiser (1959) for a sequence of interbedded siltstone and sandstone of upper Campanian to Maastrichtian age that they estimated to be 1,450 m thick.Subsequent work by Detterman and Miller (1985) examined 900 m of section and interpreted the unit as the record of a prograding submarine fan.This interpretation of deep-water deposition contrasts with other Upper Cretaceous rocks exposed along the Alaska Peninsula and lower Cook Inlet that are generally described as nonmarine to shallow marine (Detterman and others, 1996; LePain and others, 2012).Based on foraminifera and palynomorphs from the COST No. 1 well, Magoon (1986) concluded that the Upper Cretaceous rocks were deposited in a variety of water depths and environments ranging from upper bathyal to nonmarine. During our recent fieldwork west and south of Fourpeaked Mountain, we similarly encountered markedly varying lithofacies in the Kaguyak Formation (fig. 25), and we also found oil-stained rocks that are consistent with the existence of an active petroleum system in Upper Cretaceous rocks on the upper Alaska Peninsula and in lower Cook Inlet. These field observations are summarized below.

Current projections indicate that in addition to the 10,100 technician positions and 6100 existing operator positions in the nuclear power industry, another 9100 technicians and 9700 operators will be required over the next decade. With 56 nuclear plants currently in operation and an additional 35 plants under construction, it is essential that trained technical personnel be available for employment in the nuclear utilities. Because of the growing demand for technicians in the nuclear utility industry, this report has been prepared to identify the nuclear-related, less-than-baccalaureate, technical educational programs provided by academic institutions and to ascertain both the current number of students and the maximum number that could be trained, given present staff and facilities. The data serve as a gauge for the proportion of technician training required by the nuclear industry that can be provided by academic institutions

Payne, Leslie K; Glaspie, Tina

2014-06-01

Students' perceptions of their educational environment have been found to be related to their approaches to learning and learning outcomes. Educational environment is just beginning to be researched in nursing education with the vast majority of studies focusing on the clinical educational environment. Perception of educational environment has been shown to influence student implementation of a specific learning style and influences educational outcomes such as program completion and GPA. There is a need for sound research that explores the relationship, if any, between perceptions of environment and outcomes. To explore the relationship between baccalaureate nursing student (BSN) perception of educational environment (SPEE) and objective learning outcomes. Retrospective correlational descriptive study. Private School of Nursing in the Southwest. Convenience sample of 62 graduating baccalaureate students. All graduating BSN students were invited to complete the Dundee Ready Education Environment Measure (DREEM) through the online survey application Qualtrics. A total of 62 students completed the DREEM survey. These results were compared with each student's GPA and HESI score. A total of 62 students completed the survey for an overall response rate of 57%. There was no correlation between total SPEE and nursing grade point average (NGPA) or HESI exit scores. Based on this study at this institution, it appears that students' performance was not influenced by SPEE. One of the major implications of this study is the possibility that an "acceptable" SPEE (one that is neither exceptional nor terrible) may not significantly influence student outcomes. Exploring this relationship has theoretical as well as practical implications as educators seek to determine the effectiveness of educational interventions. Student perception of learning environment is measured in various ways at the majority of institutions. It has been assumed that an educational environment that is

Grade-related differences in strategy use in multidigit division in two instructional settings.

We aimed to investigate upper elementary children's strategy use in the domain of multidigit division in two instructional settings: the Netherlands and Flanders (Belgium). A cross-sectional sample of 119 Dutch and 122 Flemish fourth to sixth graders solved a varied set of multidigit division problems. With latent class analysis, three distinct strategy profiles were identified: children consistently using number-based strategies, children combining the use of column-based and number-based strategies, and children combining the use of digit-based and number-based strategies. The relation between children's strategy profiles and their instructional setting (country) and grade were generally in line with instructional differences, but large individual differences remained. Furthermore, Dutch children more frequently made adaptive strategy choices and realistic solutions than their Flemish peers. These results complement and refine previous findings on children's strategy use in relation to mathematics instruction. Statement of contribution What is already known? Mathematics education reform emphasizes variety, adaptivity, and insight in arithmetic strategies. Countries have different instructional trajectories for multidigit division. Mixed results on the impact of instruction on children's strategy use in multidigit division. What does this study add? Latent class analysis identified three meaningful strategy profiles in children from grades 4-6. These strategy profiles substantially differed between children. Dutch and Flemish children's strategy use is related to their instructional trajectory. © 2017 The Authors.

In October 1999, the two divisions of the Advanced Photon Source (APS), the Accelerator Systems Division (ASD) and the Experimental Facilities Division (XFD), were reorganized into four divisions (see high-level APS organizational chart, Fig. 1.1). In addition to ASD and XFD, two new divisions were created, the APS Operations Division (AOD), to oversee APS operations, and the User Program Division (UPD), to serve the APS user community by developing and maintaining the highest quality user technical and administration support. Previous XFD Progress Reports (ANL/APS/TB-30 and ANL/APS/TB-34) covered a much broader base, including APS user administrative support and what was previously XFD operations (front ends, interlocks, etc.) This Progress Report summarizes the main scientific and technical activities of XFD, and the technical support, research and development (R and D) activities of UPD from October 1998 through November 2000. The report is divided into four major sections, (1) Introduction, (2) SRI-CAT Beamlines, Technical Developments, and Scientific Applications, (3) User Technical Support, and (4) Major Plans for the Future. Sections 2 and 3 describe the technical activities and research accomplishments of the XFD and UPD personnel in supporting the synchrotron radiation instrumentation (SRI) collaborative access team (CAT) and the general APS user community. Also included in this report is a comprehensive list of publications (Appendix 1) and presentations (Appendix 2) by XFD and UPD staff during the time period covered by this report. The organization of section 2, SRI CAT Beamlines, Technical Developments, and Scientific Applications has been made along scientific techniques/disciplines and not ''geographical'' boundaries of the sectors in which the work was performed. Therefore items under the subsection X-ray Imaging and Microfocusing could have been (and were) performed on several different beamlines by staff in different divisions. The management of

Many collegiate schools of nursing are attempting to meet the needs of ever increasing numbers of RNs who are returning to school for the purpose of earning the baccalaureate degree. As non-traditional learners their professional and personal needs vary. Mechanisms have been developed and evaluated to assist the assessment of prior knowledge and skills. Support systems and program changes have been put in place to facilitate accomplishment of the goals of the RN student. The authors discuss ten years' experience with one RN-BSN program, and describe procedures for advance placement credit and special RN courses. Descriptive data and success measures of the 198 graduates of the original curriculum are presented as well as support systems and program changes that proved helpful. More than half of the graduates assumed positions with managerial responsibility. They were more active in professional organizations and nearly half had completed or were enrolled in graduate study. Nearly two-thirds responded positively about their derived benefits of the program listing specific courses, self-confidence, and improvement in critical thinking as some of the gains. Many noted an increased awareness of the need for nurses to work collectively in the pursuit of professional issues. This potential for development of strong leadership from this group in nursing is seen as an asset to our profession.

Maximum opening of the mouth by mouth prop during dental procedures increases the risk of upper airway constriction

Full Text Available Hiroshi Ito1, Hiroyoshi Kawaai1, Shinya Yamazaki1, Yosuke Suzuki21Division of Systemic Management, Department of Oral Function, 2Division of Radiology and Diagnosis, Department of Medical Sciences, Ohu University, Post Graduate School of Dentistry, Koriyama City, Fukushima Prefecture, JapanAbstract: From a retrospective evaluation of data on accidents and deaths during dental procedures, it has been shown that several patients who refused dental treatment died of asphyxia during dental procedures. We speculated that forcible maximum opening of the mouth by using a mouth prop triggers this asphyxia by affecting the upper airway. Therefore, we assessed the morphological changes of the upper airway following maximal opening of the mouth. In 13 healthy adult volunteers, the sagittal diameter of the upper airway on lateral cephalogram was measured between the two conditions; closed mouth and maximally open mouth. The dyspnea in each state was evaluated by a visual analog scale. In one subject, a computed tomograph (CT was taken to assess the three-dimensional changes in the upper airway. A significant difference was detected in the mean sagittal diameter of the upper airway following use of the prop (closed mouth: 18.5 ± 3.8 mm, maximally open mouth: 10.4 ± 3.0 mm. All subjects indicated upper airway constriction and significant dyspnea when their mouth was maximally open. Although a CT scan indicated upper airway constriction when the mouth was maximally open, muscular compensation was admitted. Our results further indicate that the maximal opening of the mouth narrows the upper airway diameter and leads to dyspnea. The use of a prop for the patient who has communication problems or poor neuromuscular function can lead to asphyxia. When the prop is used for patient refusal in dentistry, the respiratory condition should be monitored strictly, and it should be kept in mind that the “sniffing position” is effective for avoiding upper airway

2011-01-01

Nebraska's Upper Loup Natural Resources District is currently (2011) participating in the Elkhorn-Loup Model to understand the effect of various groundwater-management scenarios on surface-water resources. During Phase 1 of the Elkhorn-Loup Model, a lack of subsurface geological information in the Upper Loup Natural Resources District, hereafter referred to as the upper Loup study area, was identified as a gap in current knowledge that needed to be addressed. To improve the understanding of the hydrogeology of the upper Loup study area, the U.S. Geological Survey, in cooperation with the Upper Loup Natural Resources District and the University of Nebraska Conservation and Survey Division, collected and described the lithology of drill cuttings from nine test holes, and concurrently collected borehole geophysical data to identify the base of the High Plains aquifer. Surface geophysical data also were collected using time-domain electromagnetic (TDEM) and audio-magnetotelluric (AMT) methods at test-hole locations and between test holes, as a quick, non-invasive means of identifying the base of the High Plains aquifer.

Low Back Pain in Student Nurses: Literature Review and Prospective Cohort Study.

Menzel, Nancy; Feng, Du; Doolen, Jessica

2016-05-13

There is consensus that registered nurses worldwide have a high prevalence of work-related musculoskeletal disorders, particularly of the back. Patient handling activities such as lifting present the highest risk of injury, activities that begin in nursing school. A literature review identified 21 studies of back pain in nursing students, indicating a wide range of prevalence rates. A prospective cohort study of nursing students in a United States baccalaureate program followed 119 students who completed the Nordic Musculoskeletal Questionnaire upon beginning the 16 month upper division major and then a year later. There was no statistically significant change in low back pain prevalence over time. While nursing students have intermittent and brief exposure to patient handling activities, nursing schools must nevertheless protect them before they enter the high risk profession of nursing by teaching evidence-based safe patient handling techniques, empowering students to refuse unsafe manual lifts, and ensuring that the clinical settings with which they affiliate have adequate mechanical equipment available.

The Maryland nuclear science baccalaureate degree program: The university perspective

Nuclear utilities' efforts in response to industry-wide pressures to provide operations staff with degree opportunities have encountered formidable barriers. This paper describes, from the university's perspective, the development and operation of the University of Maryland University College (UMUC) special baccalaureate program in nuclear science. This program has successfully overcome these problems to provide degree education on-site, on-line, and on time. Program delivery began in 1984 with one utility and a single site. It is currently delivered at eight sites under contract to six utilities with a total active student count of over 500. The first graduates are expected in 1989. The program is an accredited university program and enjoys licensure approval from the six states within which it operates. In addition to meeting US Nuclear Regulatory Commission proposed guidelines for degreed operators, the program increasingly appears as part of utility management development programs for all plant personnel and a factor in employee retention. The owner utilities, the University of Maryland, and the growing user's group are committed to the academic integrity, technical capability, and responsiveness of the program. The full support of this partnership speaks well for the long-term service of the Bachelor of Science in Nuclear Science program to the nuclear power industry

The number of accelerated second baccalaureate degree nursing (ASBSN) programs has mushroomed over recent decades, with more than 225 currently in existence. Scholars have described students and programs, but research examining the faculty experience is limited. The purpose of this study was to describe the experiences and emotions of faculty teaching students in ASBSN programs. Using a descriptive qualitative survey design, faculty (N = 138) from 25 randomly selected programs in 11 midwestern states were surveyed using an instrument developed for this study and distributed online. Ten themes emerged, including (a) Engaging With Motivated, Mature, and Diverse Students, (b) Students Choosing Nursing for the "Wrong Reasons," (c) Too Much Work, Too Little Time for Students and Faculty, (d) Amazement, (e) Pride, and (f) Frustration. These findings will help novice and seasoned ASBSN faculty interpret their experiences, strengthen precepting and mentoring activities, and support administrators in determining staffing plans and designing ASBSN programs.

Chan, Christine K L; So, Winnie K W; Fong, Daniel Y T

2009-01-01

This study examined Hong Kong baccalaureate nursing students' stress and their coping strategies in clinical practice. Two hundred five nursing students completed a self-administrative survey including demographics, Perceived Stress Scale, and Coping Behavior Inventory. Results showed that students perceived a moderate level of stress (M = 2.10, SD =0.44). The most common stressor was lack of professional knowledge and skills. Among the four types of coping strategies (transference, stay optimistic, problem solving, and avoidance), transference was the most frequently used. Furthermore, senior students who perceived a higher level of stress from taking care of patients were more likely to choose problem-solving strategies. Senior students who had no religious belief and perceived a higher level of stress from teachers and nursing staff were more likely to use avoidance strategies. The results provided valuable information for clinical educators in identifying students' needs, facilitating their learning in the clinical setting, and developing effective interventions to reduce stress.

1998-01-01

Using Leininger's Theory of Culture Care Diversity and Universality as a framework, this research examined transcultural practices of nurses and students. A survey was administered to a convenience sample of registered nurses and senior baccalaureate students with 767 usable questionnaires returned. Neither group expressed confidence in their ability to care for culturally-diverse patients. Registered nurses (RNs) reported assessing cultural factors and modifying practices more frequently than did students. Respondents reported their beliefs about transcultural nursing were influenced by being with people of other cultures, their own personal values, and education. Analysis of the open-ended questions revealed two major themes. First, both nurses and students perceive an overwhelming need for transcultural nursing. Second, nurses and students respond to cultural challenges by modifying their care. Modifications are based on language and communication, pain perception and relief, religious and spiritual dimensions, gender and family roles, and other values. Results suggest that nurses and students are aware of culture, recognize that culture influences the care they provide, and modify their health teaching and nursing care based on culture. The use of a conceptual framework to help make modifications in care was not mentioned.

Full Text Available Mentorship has been shown to enhance engagement, participation, and understanding of the workplace through the development of soft-skills and leadership capacity. This research identifies and describes the social representations of second and third year Baccalaureate accounting students relating to their experiences in mentoring first year accounting students. We used an exploratory research method based on a qualitative analysis of 34 semi-structured interviews. Our research intends to answer these question: To what extent is a mandatory Student Peer Mentorship Project useful for second and third year Baccalaureate accounting students in developing their interpersonal and communication skills and leadership capacity?; and How can this experience be transferable to the workplace? The main results show that the mentoring experience has provided Baccalaureate students’ with the opportunity to develop their soft-skills, both interpersonal and communication skills, and has improved their leadership capacity. They took diverse actions to motivate their mentees to succeed, drawing on their own past experience of the school, program, courses, and their professors. They provided mentees with information on what to expect in the first semester in their courses as well as where, how, and when to study. These students mentioned that their intrinsic motivation, their personal satisfaction, and their leadership capacity had increased by helping and supporting their mentees. Also, they felt that they improved their communication skills through the ability to provide information and meet and support new accounting students. Finally, their experience seems as valuable for them as for their mentees and is transferable to the workplace. Il a été démontré que le mentorat améliorait l’engagement, la participation et la compréhension dans le milieu de travail grâce au développement de compétences non techniques et de capacités d’encadrement.

1994-01-01

This study compared differences in role conception (professional, bureaucratic, and service), role deprivation, and self-esteem among baccalaureate students enrolled in specially designed professional development seminars. More than 100 students participated in the pretests, given on entry to the program, of which 63 completed both the pretest and the posttest given on program exit. The Corwin Role Conception Scale assessed role conceptions and role deprivation and the Coopersmith Adult Form Self-Esteem Inventory assessed self-esteem. Statistically significant differences were found within groups in bureaucratic role conceptions (P = .0009) and self-esteem (P = .0019) and between groups in professional role conception (P = .0057). No differences were found between or within groups for service role conception or role deprivation.

Full Text Available Abstract Background In a previous study of computer operators we have demonstrated the relation of upper limb pain to individual and patterns of neurological findings (reduced function of muscles, sensory deviations from normal and mechanical allodynia of nerve trunks. The identified patterns were in accordance with neural afflictions at three specific locations (brachial plexus at chord level, posterior interosseous and median nerve on elbow level. We have introduced an intervention program aiming to mobilize nerves at these locations and tested its efficacy. Methods 125 and 59, respectively, computer operators in two divisions of an engineering consultancy company were invited to answer a questionnaire on upper limb symptoms and to undergo a blinded neurological examination. Participants in one division were subsequently instructed to participate in an upper limb stretching course at least three times during workdays in a six month period. Subjects from the other division served as controls. At the end of the intervention both groups were invited to a second identical evaluation by questionnaire and physical examination. Symptoms and findings were studied in the right upper limb. Perceived changes of pain were recorded and individual and patterns of physical findings assessed for both groups at baseline and at follow-up. In subjects with no or minimal preceding pain we additionally studied the relation of incident pain to the summarized findings for parameters contained in the definition of nerve affliction at the three locations. Results Summarized pain was significantly reduced in the intervention group but unchanged in controls. After the intervention, fewer neurological abnormalities in accordance with nerve affliction were recorded for the whole material but no conclusion could be drawn regarding the relation to the intervention of this reduction. Incident pain correlated to findings in accordance with the three locations of nerve

Examinations related to divisional differences in the incidence of sports-related concussions (SRC) in collegiate ice hockey are limited. To compare the epidemiologic patterns of concussion in National Collegiate Athletic Association (NCAA) ice hockey by sex and division. Descriptive epidemiology study. A convenience sample of men's and women's ice hockey teams in Divisions I and III provided SRC data via the NCAA Injury Surveillance Program during the 2009-2010 to 2014-2015 academic years. Concussion counts, rates, and distributions were examined by factors including injury activity and position. Injury rate ratios (IRRs) and injury proportion ratios (IPRs) with 95% confidence intervals (CIs) were used to compare concussion rates and distributions, respectively. Overall, 415 concussions were reported for men's and women's ice hockey combined. The highest concussion rate was found in Division I men (0.83 per 1000 athlete-exposures [AEs]), followed by Division III women (0.78/1000 AEs), Division I women (0.65/1000 AEs), and Division III men (0.64/1000 AEs). However, the only significant IRR was that the concussion rate was higher in Division I men than Division III men (IRR = 1.29; 95% CI, 1.02-1.65). The proportion of concussions from checking was higher in men than women (28.5% vs 9.4%; IPR = 3.02; 95% CI, 1.63-5.59); however, this proportion was higher in Division I women than Division III women (18.4% vs 1.8%; IPR = 10.47; 95% CI, 1.37-79.75). The proportion of concussions sustained by goalkeepers was higher in women than men (14.2% vs 2.9%; IPR = 4.86; 95% CI, 2.19-10.77), with findings consistent within each division. Concussion rates did not vary by sex but differed by division among men. Checking-related concussions were less common in women than men overall but more common in Division I women than Division III women. Findings highlight the need to better understand the reasons underlying divisional differences within men's and women's ice hockey and the

This integrative review synthesized baccalaureate minority nursing students' perceptions of their clinical experiences. The diversity of the nursing workforce does not mirror the United States population. Attrition rates of minority nursing students remain higher than rates for White students. Literature examining facilitators and barriers to minority student success predominantly focuses on academic factors, excluding those relevant to clinical education. An integrative review using literature from nursing and education. Three common perceived barriers were identified: discrimination from faculty, peers, nursing staff, and patients; bias in faculty grading practices; and isolation. Although little is known about the relationship between clinical failures and overall attrition, this review provides evidence that minority students encounter significant barriers in clinical education. To increase the diversity of the nursing workforce, faculty must address these issues and make modifications to ensure an equal opportunity at a quality education for all students.

Since introduction of multislice CT scanners into clinical practice, virtual brochoscopy has gained a lot of quality and diagnostic potential. Nevertheless it does not have established place in diagnostics of tracheal and bronchi disorders and its potential has not been examined enough. Nowadays a majority of bronchial tree variants and lesions are revealed by bronchofiberoscopy, which is an objective and a relatively safe method, but has side effects, especially in higher-risk subjects. Therefore noninvasive techniques enabling evaluation of airways should be consistently developed and updated. Material consisted of 100 adults (45 female, 55 male) aged between 18 and 65 years (mean 40 years, median 40.5 years, SD 14.02), who underwent chest CT examination by means of a 16-slice scanner. Every patient had normal appearance of chest organs, with the exception of minor abnormalities that did not alter airways route. Divisions of bronchial tree to segmental level were evaluated and assigned to particular types by means of virtual bronchoscopy projection. In case of difficulties MPR or MinIP projection was used. The frequency of lobar bronchi divisions other than the typical ones was in: right upper lobar bronchi 45%, left 55%; middle lobar bronchi 21%, lingula 26%; right lower lobar bronchi 28%, left 29%. Subsuperior bronchus or bronchi were found on the right side in 44% and on the left side in 37%. No dependency between types of bronchial divisions on different levels was found

The increasing complexity of the healthcare environment calls for increasing emotional intelligence (EI) competence in nurses. This study assessed the EI competence of 164 baccalaureate nursing alumni who graduated during the years 2007-2010 from three Benedictine institutions located in the Midwestern United States to see if there was growth of EI with experience as a registered nurse (RN), and to determine if age, gender, grade point average (GPA), and years of total healthcare work experience prior to graduation predicted EI. Participants completed the web-based Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and a demographic survey. Findings indicated 79.4% of participants were competent or higher on the MSCEIT total EI score. Percentages of nurses scoring in the competent or higher range on each of the four branch scores of perceiving, using, understanding and managing emotions were 80.6%, 72.7%, 84.2%, and 84.9% respectively. There were no significant differences on EI scores between graduates with 1-2 years compared to 3-5 years of experience as a RN. Results of a linear stepwise regression indicated being female was a significant predictor on the MSCEIT total EI score ( P = 0.015) and using emotions branch ( P = 0.047). Findings also indicated GPA ( P nursing graduates. Continued research on the topic of EI and nursing is needed to build the knowledge base on how to promote positive patient outcomes.

In Canada, nurse educators from five postsecondary institutions in the province of British Columbia established a collaborative nursing education initiative in 1989, with a vision to transform RN college diploma programs to baccalaureate degree programs. The principles, processes, and structures that served to develop and sustain this nursing education initiative are briefly reviewed. Curriculum, scholarship, and education legislation serve as platforms to critically explore a 25-year history (1989-2014) of successes, challenges, and transitions within this unique nursing education collaboration. The importance of curriculum development as faculty development, program evaluation as an adjunct to pedagogical scholarship, diversity of cross-institutional mandates, political interplay in nursing education, collegiality, and courageous leadership are highlighted. Nurse educators seeking to create successful collaborations must draw upon well-defined principles and organizational structures and processes to guide pedagogical practices and inquiry while remaining mindful of and engaged in professional and societal developments.

A series of three baccalaureate Nursing Leadership and Patient-Centered Care (NLPCC) courses were developed to strengthen students' perceptions and preparation as leaders in the delivery of patient-centered care through more effective professional socialization. A mixed-methods design was used, administering two surveys to students at the start of the junior year and the end of their senior year, plus two qualitative questions were administered after the second-semester junior and senior years. Qualitative data reflected a growing awareness of the professional nurse's role and responsibilities beyond the bedside. Graduating senior students demonstrated a heightened awareness for the socialization and realities of practice and a growing sense of readiness and empowerment to embrace the professional role of an RN. Through role modeling, scripted conversations, and focused dialogue, the infusion of knowledge, skills, and attitudes from the Quality and Safety Education for Nurses competencies allowed students to hone their socialization skills prior to entering the workforce.

Integrating Spiritual Care into a Baccalaureate Nursing Program in Mainland China.

Yuan, Hua; Porr, Caroline

2014-09-01

Holistic nursing care takes into account individual, family, community and population well-being. At the level of individual well-being, the nurse considers biological, psychological, social, and spiritual factors. However, in Mainland China spiritual factors are not well understood by nursing students. And accordingly, nursing faculty and students are reluctant to broach the topic of spirituality because it is either unknown to students or students believe that the provision of spiritual care is beyond their capabilities. We wonder then, what can we do as nurse educators to integrate spiritual care into a baccalaureate nursing program in Mainland China? The purpose of this article is to propose the integration of Chinese sociocultural traditions (namely religious/spiritual practices) into undergraduate nursing curricula as a means to enter into dialogue about spiritual well-being, to promote spiritual care; and to fulfill the requirements of holistic nursing care. However, prior to discussing recommendations, an overview of the cultural context is in order. Thus, this article is constructed as follows: first, the complexity of Chinese society is briefly described; second, the historical evolution of nursing education in Mainland China is presented; and, third, strategies to integrate Chinese religious/spiritual practices into curricula are proposed. © The Author(s) 2014.

Gray, Mary Tod

2010-05-01

This longitudinal descriptive study evaluates the implementation of an innovative teaching strategy: a research partnership between baccalaureate nursing students and nurses in two acute care hospitals. The impetus for this partnership was to introduce a concrete, clinical dimension to a junior level introductory nursing research course. Formative analysis was used to evaluate the success and weaknesses of this innovative strategy over 3 years. Following each year, an evaluation by students and nursing unit managers led to refinement of the partnership goals and logistics for the following year. The third year culminates in a comparison between student responses to the partnership in the small community hospital and those assigned to a larger magnet status hospital. Conclusions, based on content and descriptive analysis indicate the partnership's educational benefits for students and a few logistical concerns. Future directions for this educational strategy are presented. Copyright 2009 Elsevier Ltd. All rights reserved.

Upper facial port-wine stain (PWS) is a feature of Sturge-Weber syndrome (SWS). Recent studies suggest that the distribution of the PWS corresponds to genetic mosaicism rather than to trigeminal nerve impairment. We sought to refine the cutaneous distribution of upper facial PWS at risk for SWS. This was a prospective multicenter study of consecutive cases of upper facial PWS larger than 1 cm² located in the ophthalmic division of trigeminal nerve distribution in infants aged less than 1 year, seen in 8 French pediatric dermatology departments between 2006 and 2012. Clinical data, magnetic resonance imaging, and photographs were systematically collected and studied. PWS were classified into 6 distinct patterns. In all, 66 patients were included. Eleven presented with SWS (magnetic resonance imaging signs and seizure). Four additional infants had suspected SWS without neurologic manifestations. Hemifacial (odds ratio 7.7, P = .003) and median (odds ratio 17.08, P = .008) PWS patterns were found to be at high risk for SWS. A nonmedian linear pattern was not associated with SWS. Small number of patients translated to limited power of the study. Specific PWS distribution patterns are associated with an increased risk of SWS. These PWS patterns conform to areas of somatic mosaicism. Terminology stipulating ophthalmic division of trigeminal nerve territory involvement in SWS should be abandoned.

Ebersbach, Gitte; Galli, Elizabeth; Møller-Jensen, Jakob

2008-01-01

Formation of the Z ring is the first known event in bacterial cell division. However, it is not yet known how the assembly and contraction of the Z ring is regulated. Here, we identify a novel cell division factor ZapB in Escherichia coli that simultaneously stimulates Z ring assembly and cell...... division. Deletion of zapB resulted in delayed cell division and the formation of ectopic Z rings and spirals whereas overexpression of ZapB resulted in nucleoid condensation and aberrant cell divisions. Localization of ZapB to the divisome depended on FtsZ but not FtsA, ZipA or FtsI and ZapB interacted...... with FtsZ in a bacterial two-hybrid analysis. The simultaneous inactivation of FtsA and ZipA prevented Z ring assembly and ZapB localization. Time lapse microscopy showed that ZapB-GFP is present at mid-cell in a pattern very similar to that of FtsZ. Cells carrying a zapB deletion and the ftsZ84ts allele...

Gastrointestinal (GI) bleeding is a common surgical problem. The aim of this study was to evaluate how insertion of the nasogastric tube may enable differentiation between upper and lower GI bleeding in patients with melena. A retrospective study involving patients admitted to our surgery division with a melena was carried out between the years 2010 and 2012. A total of 386 patients were included in the study. Of these, 279 (72.2%) patients had negative nasogastric aspirate. The sensitivity of examination of nasogastric aspirate to establish the upper GI as the source of bleeding was only 28% and the negative predictive value of a negative nasogastric aspirate was less than 1%. Most patients who initially presented with melena and were found to have upper GI bleeding had a negative nasogastric aspirate. Insertion of a nasogastric tube does not affect the clinical decision to perform upper endoscopy and should not be routinely carried out.

Factors affecting the social problem-solving ability of baccalaureate nursing students.

Science.gov (United States)

Lau, Ying

2014-01-01

The hospital environment is characterized by time pressure, uncertain information, conflicting goals, high stakes, stress, and dynamic conditions. These demands mean there is a need for nurses with social problem-solving skills. This study set out to (1) investigate the social problem-solving ability of Chinese baccalaureate nursing students in Macao and (2) identify the association between communication skill, clinical interaction, interpersonal dysfunction, and social problem-solving ability. All nursing students were recruited in one public institute through the census method. The research design was exploratory, cross-sectional, and quantitative. The study used the Chinese version of the Social Problem Solving Inventory short form (C-SPSI-R), Communication Ability Scale (CAS), Clinical Interactive Scale (CIS), and Interpersonal Dysfunction Checklist (IDC). Macao nursing students were more likely to use the two constructive or adaptive dimensions rather than the three dysfunctional dimensions of the C-SPSI-R to solve their problems. Multiple linear regression analysis revealed that communication ability (ß=.305, pproblem-solving after controlling for covariates. Macao has had no problem-solving training in its educational curriculum; an effective problem-solving training should be implemented as part of the curriculum. With so many changes in healthcare today, nurses must be good social problem-solvers in order to deliver holistic care. Copyright © 2012 Elsevier Ltd. All rights reserved.

Collaborative testing: assessing teamwork and critical thinking behaviors in baccalaureate nursing students.

Science.gov (United States)

Wiggs, Carol M

2011-04-01

The purpose of this study was to foster teamwork and critical thinking behaviors in baccalaureate nursing students using a collaborative testing environment. Collaborative testing affords the nurse educator a unique opportunity to actively influence the development of critical thinking skills directly influencing the nursing student's ability to solve complex patient problems. Using a quasi-experimental approach exam scores from students in prior semesters were compared to students in several semesters using collaborative testing in one undergraduate course taught by the same faculty. In the experimental group collaborative testing was used in the two unit examinations, while the final examination remained individual. For collaborative testing the students were grouped by random assignment. They were not allowed the use of notes, textbooks, or other resource materials. Any student who wished to work alone was allowed do so and any student coming late (within 15 min of examination beginning) was required to work alone. Each student submitted individual examination answer forms, and groups were not required to reach consensus. Collaborative testing is one means to foster critical thinking by allowing students to solve complex patient problems within an examination environment. This better prepares them for national certification exams. Copyright © 2010 Elsevier Ltd. All rights reserved.

Impetus and Creation of an Accelerated Second-Degree Baccalaureate Nursing Program Readmission Policy

Directory of Open Access Journals (Sweden)

Joanne Schwartz PhD, PMHNP-BC, CNE

2017-04-01

Full Text Available An accelerated second-degree baccalaureate nursing (ASDBN is an academic plan of study typically 12 to 24 months in duration. ASDBN students make many changes when entering this type of program. Some of the major changes ASDBN students make when entering an ASDBN program include leaving jobs, incurring debt, draining financial resources, forgoing time with children, spouses, and significant others, and, in some cases, relocating far from family and support systems. Because of the nature and scope of the many sacrifices ASDBN students typically make, academic program dismissal is particularly traumatic and devastating. It is not uncommon for an ASDBN student to seek program readmission when they are dismissed for academic reasons. Many academically dismissed ASDBN students seek program readmission. Administrators face a challenging decision in program readmission requests. The key issue with program readmission of ASDBN students is having a rigorous and comprehensive policy to determine which ASDBN students should be readmitted. This article examines one large, private, urban university’s ASDBN program’s readmission policy design and how the policy is applied to manage and determine ASDBN program readmission requests.

Insights into the Mechanisms of Chloroplast Division

Directory of Open Access Journals (Sweden)

Yamato Yoshida

2018-03-01

Full Text Available The endosymbiosis of a free-living cyanobacterium into an ancestral eukaryote led to the evolution of the chloroplast (plastid more than one billion years ago. Given their independent origins, plastid proliferation is restricted to the binary fission of pre-existing plastids within a cell. In the last 25 years, the structure of the supramolecular machinery regulating plastid division has been discovered, and some of its component proteins identified. More recently, isolated plastid-division machineries have been examined to elucidate their structural and mechanistic details. Furthermore, complex studies have revealed how the plastid-division machinery morphologically transforms during plastid division, and which of its component proteins play a critical role in generating the contractile force. Identifying the three-dimensional structures and putative functional domains of the component proteins has given us hints about the mechanisms driving the machinery. Surprisingly, the mechanisms driving plastid division resemble those of mitochondrial division, indicating that these division machineries likely developed from the same evolutionary origin, providing a key insight into how endosymbiotic organelles were established. These findings have opened new avenues of research into organelle proliferation mechanisms and the evolution of organelles.

Capmany, J; Pastor, D; Sales, S; Ortega, B

2002-06-01

We present a closed-form expression for computation of the output pulse's rms time width in an optical fiber link with up to fourth-order dispersion (FOD) by use of an optical source with arbitrary linewidth and chirp parameters. We then specialize the expression to analyze the effect of FOD on the transmission of very high-speed linear optical time-division multiplexing systems. By suitable source chirping, FOD can be compensated for to an upper link-length limit above which other techniques must be employed. Finally, a design formula to estimate the maximum attainable bit rate limited by FOD as a function of the link length is also presented.

Identification of cognitive and non-cognitive predictive variables related to attrition in baccalaureate nursing education programs in Mississippi

Science.gov (United States)

Hayes, Catherine

2005-07-01

This study sought to identify a variable or variables predictive of attrition among baccalaureate nursing students. The study was quantitative in design and multivariate correlational statistics and discriminant statistical analysis were used to identify a model for prediction of attrition. The analysis then weighted variables according to their predictive value to determine the most parsimonious model with the greatest predictive value. Three public university nursing education programs in Mississippi offering a Bachelors Degree in Nursing were selected for the study. The population consisted of students accepted and enrolled in these three programs for the years 2001 and 2002 and graduating in the years 2003 and 2004 (N = 195). The categorical dependent variable was attrition (includes academic failure or withdrawal) from the program of nursing education. The ten independent variables selected for the study and considered to have possible predictive value were: Grade Point Average for Pre-requisite Course Work; ACT Composite Score, ACT Reading Subscore, and ACT Mathematics Subscore; Letter Grades in the Courses: Anatomy & Physiology and Lab I, Algebra I, English I (101), Chemistry & Lab I, and Microbiology & Lab I; and Number of Institutions Attended (Universities, Colleges, Junior Colleges or Community Colleges). Descriptive analysis was performed and the means of each of the ten independent variables was compared for students who attrited and those who were retained in the population. The discriminant statistical analysis performed created a matrix using the ten variable model that was able to correctly predicted attrition in the study's population in 77.6% of the cases. Variables were then combined and recombined to produce the most efficient and parsimonious model for prediction. A six variable model resulted which weighted each variable according to predictive value: GPA for Prerequisite Coursework, ACT Composite, English I, Chemistry & Lab I, Microbiology

We have previously examined the professional self-image of practicing nurses in Belgium and its association with various professional decisions, however there is limited knowledge about the professional self-image of nurses-to-be. Despite prior research on nursing students' perceptions of nursing or their self-esteem, students' professional image, defined as "the way students perceive themselves in their clinical practice environment and their anticipated work environment", has not been described nor compared to that of practicing nurses. To describe the professional nursing self-image among students in their final year of baccalaureate education. Cross-sectional survey. Nine geographically spread baccalaureate programs in the Flemish region of Belgium. 427 evaluable students from 455 recruited from 663 potential. Data collected in each school during regular hours using an adapted version of the BELIMAGE (Belgian professional self-image instrument for hospital nurses) including questions on personal demographics, education and competence, nursing care, team and practice environment. Voluntary participation with returned questionnaire deemed informed consent. Respondents identified several curricular components as contributing to their perceived competence. They also identified several skills deemed important to professional nursing, however did not feel competent in all of these. Important nursing care aspects included individualizing patient care, detecting care problems and potential complications, and promoting patient well-being; within a care environment with open interdisciplinary communication, where care problems could be discussed with nursing colleagues, where one cares for the same patient regularly, and led by a team leader with vision. Society's view of nursing was generally more negative than students'. Most students planned on working in nursing after their studies and many had thought about additional education at some point. Most were proud of

Review of student difficulties in upper-level quantum mechanics

Full Text Available [This paper is part of the Focused Collection on Upper Division Physics Courses.] Learning advanced physics, in general, is challenging not only due to the increased mathematical sophistication but also because one must continue to build on all of the prior knowledge acquired at the introductory and intermediate levels. In addition, learning quantum mechanics can be especially challenging because the paradigms of classical mechanics and quantum mechanics are very different. Here, we review research on student reasoning difficulties in learning upper-level quantum mechanics and research on students’ problem-solving and metacognitive skills in these courses. Some of these studies were multiuniversity investigations. The investigations suggest that there is large diversity in student performance in upper-level quantum mechanics regardless of the university, textbook, or instructor, and many students in these courses have not acquired a functional understanding of the fundamental concepts. The nature of reasoning difficulties in learning quantum mechanics is analogous to reasoning difficulties found via research in introductory physics courses. The reasoning difficulties were often due to overgeneralizations of concepts learned in one context to another context where they are not directly applicable. Reasoning difficulties in distinguishing between closely related concepts and in making sense of the formalism of quantum mechanics were common. We conclude with a brief summary of the research-based approaches that take advantage of research on student difficulties in order to improve teaching and learning of quantum mechanics.

Impact of energy development on water resources in the Upper Colorado River Basin. Completion report

International Nuclear Information System (INIS)

Flug, M.; Walker, W.R.; Skogerboe, G.V.; Smith, S.W.

1977-08-01

The Upper Colorado River Basin contains appreciable amounts of undeveloped coal, oil shale, and uranium resources, which are important in the national energy demand system. A mathematical model, which simulates the salt and water exchange phase of potential fuel conversions, has been developed, based on a subbasin analysis identifying available mineral and water resources. Potential energy developments are evaluated with respect to the resulting impacts upon both the quantity and salinity of the waters in the Colorado River. Model solutions are generated by use of a multilevel minimum cost linear programming algorithm, minimum cost referring to the cost of developing predetermined levels of energy output. Level one in the model analysis represents an aggregation of subbasins along state boundaries and thereby optimizes energy developments over the five states of the Upper Colorado River Basin. In each of the five second level problems, energy developments over a subbasin division within the respective states are optimized. Development policies which use high salinity waters of the Upper Colorado River enable a net salinity reduction to be realized in the Colorado River at Lee Ferry, Arizona

2009-07-01

Research supports the use of preactivity warm-up and stretching, and the purpose of this study was to determine whether college football programs follow these guidelines. Questionnaires designed to gather demographic, professional, and educational information, as well as specific pre- and postactivity practices, were distributed via e-mail to midwestern collegiate programs from NCAA Division I and III conferences. Twenty-three male coaches (12 from Division IA schools and 11 from Division III schools) participated in the study. Division I schools employed certified strength coaches (CSCS; 100%), whereas Division III schools used mainly strength coordinators (73%), with only 25% CSCS. All programs used preactivity warm-up, with the majority employing 2-5 minutes of sport-specific jogging/running drills. Pre stretching (5-10 minutes) was performed in 19 programs (91%), with 2 (9%) performing no pre stretching. Thirteen respondents used a combination of static/proprioceptive neuromuscular facilitation/ballistic and dynamic flexibility, 5 used only dynamic flexibility, and 1 used only static stretching. All 12 Division I coaches used stretching, whereas only 9 of the 11 Division III coaches did (p = 0.22). The results indicate that younger coaches did not use pre stretching (p = 0.30). The majority of the coaches indicated that they did use post stretching, with 11 of the 12 Division I coaches using stretching, whereas only 5 of the 11 Division III coaches used stretching postactivity (p = 0.027). Divisional results show that the majority of Division I coaches use static-style stretching (p = 0.049). The results of this study indicate that divisional status, age, and certification may influence how well research guidelines are followed. Further research is needed to delineate how these factors affect coaching decisions.

Sustainability Science as a Transdisciplinary Framework for Institutional Transformation at Unity College

Science.gov (United States)

Mulkey, S. S.

2012-12-01

Interdisciplinary programming in higher education is accepted as necessary for effective instructional delivery of complex environmental problems. Difficulties in sharing resources among disciplinary units and the need for students to sequentially access information from different disciplines limit the effectiveness of this approach. In contrast, transdisciplinary programming requires that the perspectives of various disciplines be simultaneously integrated in problem-focused pedagogy. Unity College, an environmental college in Maine, has recently adopted Sustainability Science (sensu U.S. National Academy of Science) as a framework for transdisciplinary pedagogy throughout all of its degree programs. Sustainability Science is a promising alternative framework that focuses on the dynamics of coupled human-natural systems and is defined by the problems that it addresses rather than by the disciplines it employs. Students are empowered to become brokers of knowledge, while faculty perform a curatorial role to provide students with networked resources generally external to the classroom. Although the transdisciplinary framework is effective for delivery of Sustainability Science in upper division and capstone courses, we propose this approach also for elements of our general education curriculum during the first two years of our baccalaureate programs. Classroom time is liberated for experiential student engagement and recitation. Our experience suggests that transdisciplinary programming can provide students with critical thinking skills and thus enhance the postgraduate value of their baccalaureate degree. We are coordinating the development of this distinctive curriculum delivery with a marketing program that will make Unity College accessible to a wider range of clientele. Our implementation of transdisciplinary programming will occur over a four-year period and requires explicit and fundamental change in essentially all aspects of College administration and

BACKGROUND Persons with class II division 2 malocclusion are characterized by a very specific dento-skeletal and soft-tissue profile (a profile in which a protruding nose and chin, retruding lips, concave and shortened lower third of the face, and gummy smile are dominant), which is the opposite of the currently modern profiles (convex profile of protruding lips and small chin). The aim of this research was to determine the differences in parameters of harmonies of facial profiles between persons with class II division 2 malocclusions and class I, and to establish the significance of those differences. MATERIAL AND METHODS For this study, 50 patients with class II division 2 malocclusions and 50 patients with class I were selected; profile photos were recorded and a photometric analysis was done: a type of profile according to Schwarz, the shape of a nose, the prominence of chin, biometrical field, the position of lips in relation to the tangent Sn-Pg, S-line (Steiner), E-line (Riketts) and a facial angle according to Arnett. RESULTS The significant differences in profiles of persons with class II division 2 compared to class I were: position and prominence of the chin, the position of the lower and upper lip in relation to the S-line, and smaller value of a facial angle in relation to persons with class I. CONCLUSIONS The differences seen in skeletal profiles were not associated with significant differences in the profiled facial contours of the examined groups. The compensatory role of the fullness of soft tissues of the lips is probably the reason why there were not significant deviations in all the examined parameters.

This study investigated the critical thinking dispositions and skills of senior nursing students. Study participants were students enrolled in associate (n = 137), baccalaureate (n = 102), and RN-to-BSN (n = 66) programs accredited by the Korean Ministry of Education. The California Critical Thinking Disposition Inventory (CCTDI) and California Critical Thinking Skills Test (CCTST) were used. A comparison of the CCTDI scores revealed a statistically significant difference between the students enrolled in different programs (F = 4.159, p = 0.017), as did a comparison of the CCTST scores (F = 24.205, p critical thinking skills to make the decisions required of them in their nursing practice. In line with this, when conducting a survey of the effectiveness of nursing education, the necessity of critical thinking skills cannot be overlooked. In fact, the National League for Nursing Accrediting Commission (NLNAC) (1999) and American Association of Colleges of Nursing (AACN) (1998) require the concept of critical thinking be included as one of the core elements of curricula and that it be measured as an outcome when evaluating nursing education. In 1998, during the evaluation of colleges of nursing conducted by the South Korean Council for University Education, several universities presented the fostering of critical thinking as one of the terminal learning goals of nursing education based on the idea that critical thinking is important not only in the nursing workplace, but also in nursing education. To evaluate the effectiveness of Korea's current nursing education curriculum, focus was placed on current students in South Korea's three systems of nursing education. Each curriculum's effectiveness can be evaluated by indexing critical thinking dispositions and skills. This article intends to offer insight into the first steps necessary in reorganizing nursing education by comparing these evaluations of each of the three systems. To this end, we conducted a comparative

FtsZ-less prokaryotic cell division as well as FtsZ- and dynamin-less chloroplast and non-photosynthetic plastid division

Directory of Open Access Journals (Sweden)

Shin-Ya eMiyagishima

2014-09-01

Full Text Available The chloroplast division machinery is a mixture of a stromal FtsZ-based complex descended from a cyanobacterial ancestor of chloroplasts and a cytosolic dynamin-related protein (DRP 5B-based complex derived from the eukaryotic host. Molecular genetic studies have shown that each component of the division machinery is normally essential for normal chloroplast division. However, several exceptions have been found. In the absence of the FtsZ ring, nonphotosynthetic plastids are able to proliferate, likely by elongation and budding. Depletion of DRP5B impairs, but does not stop chloroplast division. Chloroplasts in glaucophytes, which possesses a peptidoglycan (PG layer, divide without DRP5B. Certain parasitic eukaryotes possess nonphotosynthetic plastids of secondary endosymbiotic origin, but neither FtsZ nor DRP5B is encoded in their genomes. Elucidation of the FtsZ- and/or DRP5B-less chloroplast division mechanism will lead to a better understanding of the function and evolution of the chloroplast division machinery and the finding of the as-yet-unknown mechanism that is likely involved in chloroplast division. Recent studies have shown that FtsZ was lost from a variety of prokaryotes, many of which lost PG by regressive evolution. In addition, even some of the FtsZ-bearing bacteria are able to divide when FtsZ and PG are depleted experimentally. In some cases, alternative mechanisms for cell division, such as budding by an increase of the cell surface-to-volume ratio, are proposed. Although PG is believed to have been lost from chloroplasts other than in glaucophytes, there is some indirect evidence for the existence of PG in chloroplasts. Such information is also useful for understanding how nonphotosynthetic plastids are able to divide in FtsZ-depleted cells and the reason for the retention of FtsZ in chloroplast division. Here we summarize information to facilitate analyses of FtsZ- and/or DRP5B-less chloroplast and nonphotosynthetic plastid

Full Text Available The aim of this article is to present the International Baccalaureate (IB Programme and briefly outline its core components, followed by a review of what authoritative reports identify as skills for the future, esteemed by universities and the job market. There is a striking match between these skills and IB outcomes; thus, DP graduates perform well in higher education and add to the reputation of those institutions. After a review of the literature, the authors found the IB Diploma Programme has been studied in many countries by both consultants and educational agencies, and also by a wide array of universities themselves; however, there are fewer qualitative studies concerning the degree to which IB graduates display attitudes, values, and behaviours in line with the IB Learner Profile. This is why the authors stress the claims made are supported by examples of significant research, noting that there is a dearth of qualitative longitudinal studies to sufficiently substantiate the affective domain claims that currently rely more on anecdotal evidence. The authors conclude by pointing out more research is needed in order to substantiate anecdotal evidence regarding future employment success for IB Diploma Programme graduates.  DOI: 10.18870/hlrc.v4i3.123

Full Text Available Objective: The increasing complexity of the healthcare environment calls for increasing emotional intelligence (EI competence in nurses. This study assessed the EI competence of 164 baccalaureate nursing alumni who graduated during the years 2007-2010 from three Benedictine institutions located in the Midwestern United States to see if there was growth of EI with experience as a registered nurse (RN, and to determine if age, gender, grade point average (GPA, and years of total healthcare work experience prior to graduation predicted EI. Methods: Participants completed the web-based Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT and a demographic survey. Results: Findings indicated 79.4% of participants were competent or higher on the MSCEIT total EI score. Percentages of nurses scoring in the competent or higher range on each of the four branch scores of perceiving, using, understanding and managing emotions were 80.6%, 72.7%, 84.2%, and 84.9% respectively. There were no significant differences on EI scores between graduates with 1-2 years compared to 3-5 years of experience as a RN. Results of a linear stepwise regression indicated being female was a significant predictor on the MSCEIT total EI score (P = 0.015 and using emotions branch (P = 0.047. Findings also indicated GPA (P < 0.001 and being female (P = 0.023 were significant predictors of EI on the understanding emotions branch. Conclusions: The findings indicate there is work to be done to improve the EI competence of nursing graduates. Continued research on the topic of EI and nursing is needed to build the knowledge base on how to promote positive patient outcomes.

The division was formed in 1946 at the suggestion of Dr. Eugene P. Wigner to attack the problem of the distortion of graphite in the early reactors due to exposure to reactor neutrons, and the consequent radiation damage. It was called the Metallurgy Division and assembled the metallurgical and solid state physics activities of the time which were not directly related to nuclear weapons production. William A. Johnson, a Westinghouse employee, was named Division Director in 1946. In 1949 he was replaced by John H Frye Jr. when the Division consisted of 45 people. He was director during most of what is called the Reactor Project Years until 1973 and his retirement. During this period the Division evolved into three organizational areas: basic research, applied research in nuclear reactor materials, and reactor programs directly related to a specific reactor(s) being designed or built. The Division (Metals and Ceramics) consisted of 204 staff members in 1973 when James R. Weir, Jr., became Director. This was the period of the oil embargo, the formation of the Energy Research and Development Administration (ERDA) by combining the Atomic Energy Commission (AEC) with the Office of Coal Research, and subsequent formation of the Department of Energy (DOE). The diversification process continued when James O. Stiegler became Director in 1984, partially as a result of the pressure of legislation encouraging the national laboratories to work with U.S. industries on their problems. During that time the Division staff grew from 265 to 330. Douglas F. Craig became Director in 1992.

Simulation With Debriefing and Guided Reflective Journaling to Stimulate Critical Thinking in Prelicensure Baccalaureate Degree Nursing Students.

Science.gov (United States)

Padden-Denmead, Mary L; Scaffidi, Rose M; Kerley, Regina M; Farside, Amy Lee

2016-11-01

Simulation and guided reflective journaling have been identified as effective teaching and learning methods to develop critical thinking (CT) and clinical reasoning skills in nursing students. A descriptive correlational design was used to determine the relationship between CT and level of reflection using the Holistic Critical Thinking Skills Rubric (HCTSR) and the level of reflection on action assessment (LORAA), respectively, to evaluate 23 baccalaureate student-guided reflective journal entries after a simulation exercise with guided debriefing and after two subsequent clinical experiences. A statistically significant positive relationship (p < .01) was found between mean HCTSR and LORAA scores on all three journal entries, but no relationship to CT during simulation or on standardized test scores. The results also indicated support for use of the guided reflection after significant learning experiences. The LORAA and the HCTSR are effective measures of level of reflection and CT to evaluate learning from simulation and clinical experiences. [J Nurs Educ. 2016;55(11):645-650.].

Research funded primarily by the NRC is directed toward assessing the roles of cyclic fatigue, intergranular stress corrosion cracking, and irradiation-assisted stress corrosion cracking on failures in light water reactor (LWR) piping systems, pressure vessels, and various core components. In support of the fast reactor program, the Division has responsibility for fuel-performance modeling and irradiation testing. The Division has major responsibilities in several design areas of the proposed International Thermonuclear Experimental Reactor (ITER). The Division supports the DOE in ensuring safe shipment of nuclear materials by providing extensive review of the Safety Analysis Reports for Packaging (SARPs). Finally, in the nuclear area they are investigating the safe disposal of spent fuel and waste. In work funded by DOE`s Energy Efficiency and Renewable Energy, the high-temperature superconductivity program continues to be a major focal point for industrial interactions. Coatings and lubricants developed in the division`s Tribology Section are intended for use in transportation systems of the future. Continuous fiber ceramic composites are being developed for high-performance heat engines. Nondestructive testing techniques are being developed to evaluate fiber distribution and to detect flaws. A wide variety of coatings for corrosion protection of metal alloys are being studied. These can increase lifetimes significant in a wide variety of coal combustion and gasification environments.

2015-04-01

Persistently high medical error rates, caregiver dissatisfaction, and compromised patient safety often result from poorly coordinated, increasingly complex health care. Barriers to interprofessional health professions education persist despite the urgent calls for improved quality and safety. Investigators explored the effects of a problem-based learning (PBL) strategy between prelicensure doctorate of pharmacy (PharmD) and baccalaureate nursing (BSN) students. A descriptive design was used to compare the learning gains and satisfaction with a PBL hybrid approach for BSN and PharmD prelicensure student groups over three academic terms. Consistent with earlier works, content-based learning gains and student satisfaction were not significantly different between groups. Narrative data provide insight into perceived benefits, barriers, and perspectives of participating students and facilitators. Attributes of this pedagogical approach provide opportunity for prelicensure students to explore professional interdependence while adequately mastering fact-based content.

The stem cell division theory of cancer.

Science.gov (United States)

López-Lázaro, Miguel

2018-03-01

All cancer registries constantly show striking differences in cancer incidence by age and among tissues. For example, lung cancer is diagnosed hundreds of times more often at age 70 than at age 20, and lung cancer in nonsmokers occurs thousands of times more frequently than heart cancer in smokers. An analysis of these differences using basic concepts in cell biology indicates that cancer is the end-result of the accumulation of cell divisions in stem cells. In other words, the main determinant of carcinogenesis is the number of cell divisions that the DNA of a stem cell has accumulated in any type of cell from the zygote. Cell division, process by which a cell copies and separates its cellular components to finally split into two cells, is necessary to produce the large number of cells required for living. However, cell division can lead to a variety of cancer-promoting errors, such as mutations and epigenetic mistakes occurring during DNA replication, chromosome aberrations arising during mitosis, errors in the distribution of cell-fate determinants between the daughter cells, and failures to restore physical interactions with other tissue components. Some of these errors are spontaneous, others are promoted by endogenous DNA damage occurring during quiescence, and others are influenced by pathological and environmental factors. The cell divisions required for carcinogenesis are primarily caused by multiple local and systemic physiological signals rather than by errors in the DNA of the cells. As carcinogenesis progresses, the accumulation of DNA errors promotes cell division and eventually triggers cell division under permissive extracellular environments. The accumulation of cell divisions in stem cells drives not only the accumulation of the DNA alterations required for carcinogenesis, but also the formation and growth of the abnormal cell populations that characterize the disease. This model of carcinogenesis provides a new framework for understanding the

The Chemical Technology Division (CMT) is one of eight engineering research divisions within Argonne National Laboratory (ANL), one of the U.S. government's oldest and largest research laboratories. The University of Chicago oversees the laboratory on behalf of the U.S. Department of Energy (DOE). Argonne's mission is to conduct basic scientific research, to operate national scientific facilities, to enhance the nation's energy resources, and to develop better ways to manage environmental problems. Argonne has the further responsibility of strengthening the nation's technology base through developing industrial technology and transferring that technology to industry. The Chemical Technology Division is a diverse early-stage engineering organization, specializing in the treatment of spent nuclear fuel, development of advanced power sources, and management of both high- and low-level nuclear wastes. Although this work is often indistinguishable from basic research, our efforts are directed toward the practical devices and processes that are covered by ANL's mission. Additionally, the Division operates the Analytical Chemistry Laboratory, which provides a broad range of analytical services to ANL and other organizations. The Division is multi-disciplinary. Its people have formal training as ceramists; physicists; material scientists; electrical, mechanical, chemical, and nuclear engineers; and chemists. They have experience working in academia, urban planning, and the petroleum, aluminum, and automotive industries. Their skills include catalysis, ceramics, electrochemistry, metallurgy, nuclear magnetic resonance spectroscopy, and petroleum refining, as well as the development of nuclear waste forms, batteries, and high-temperature superconductors. In this annual report we present an overview of the technical programs together with representative highlights. The report is not intended to be comprehensive or encyclopedic, but to serve as an indication of the condition

Nuclear size and cell division delay

International Nuclear Information System (INIS)

Bird, R.P.

1986-01-01

Radiation-induced division delay has been linked to damage at the nuclear envelope. Further, cells in G 2 phase are drastically arrested by high LET radiation such that single particles traversing cell nuclei may produce measurable division delay. A modest effort was initiated using two related cell lines of different size, near-diploid cells and near-tetraploid cells of Chinese hamster origin, to compare their sensitivity for radiation-induced division delay. If the nuclear surface is the critical target, then a larger nuclear cross-section presented to an alpha-particle beam should exhibit delay induced by a lesser particle fluence. Preliminary estimates of the extent of delay in asynchronous cultures following low doses of gamma-irradiation or of alpha-irradiation were made by in-situ observation of the time of onset of mitosis and by fixation and staining of cultures to determine the mitotic index as a function of time after irradiation. The basic approach to evaluating division delay will be to use Colecemid to accumulate mitotic cells over a period of time

Parallel optoelectronic trinary signed-digit division

Science.gov (United States)

Alam, Mohammad S.

1999-03-01

The trinary signed-digit (TSD) number system has been found to be very useful for parallel addition and subtraction of any arbitrary length operands in constant time. Using the TSD addition and multiplication modules as the basic building blocks, we develop an efficient algorithm for performing parallel TSD division in constant time. The proposed division technique uses one TSD subtraction and two TSD multiplication steps. An optoelectronic correlator based architecture is suggested for implementation of the proposed TSD division algorithm, which fully exploits the parallelism and high processing speed of optics. An efficient spatial encoding scheme is used to ensure better utilization of space bandwidth product of the spatial light modulators used in the optoelectronic implementation.

The first assignment of DNA polymerases at the eukaryotic replication fork was possible after the in vitro reconstitution of the simian virus 40 (SV40) replication system. In this system, DNA polymerase α (Pol α) provides both leading and lagging strands with RNA-DNA primers that are extended by DNA polymerase δ (Pol δ). Extrapolating the architecture of the replication fork from the SV40 model system to an actual eukaryotic cell has been challenged by the discovery of a third DNA polymerase in Saccharomyces cerevisiae, DNA polymerase ε (Pol ε). A division of labor has been proposed for the eukaryotic replication fork whereby Pol ε replicates the leading strand and Pol δ replicates the lagging strand. However, an alternative model of unequal division of labor in which Pol δ can still participate in leading-strand synthesis is plausible.

This article is a report of a Neuman Systems Model-guided correlational study of the relations of stress resiliency, psychological empowerment, selected demographic characteristics (age, ethnicity, semester in school) and conflict management styles. Emerging evidence suggests that stress resiliency and psychological empowerment can strengthen student nurses in academic achievement and coping with stress. Little is known about conflict management styles of students and the relationship to empowerment, resiliency and the implications for managing workplace conflict. A correlational study was conducted in Spring 2010 with 166 baccalaureate students. Most participants were female, single, Hispanic and 25 years old. The data collection instruments included the Stress Resiliency Profile, the Psychological Empowerment Instrument, the Conflict Mode Instrument and a demographic inventory. Descriptive and inferential correlational statistics were used to analyse the data. Students scored in the high range for focusing on their deficiencies in conflict situations; they scored above the 60th percentile for avoiding and accommodating behaviours and were less likely to use competing or collaborating strategies to manage conflict. Empowerment scores were significantly correlated with stress resiliency scores. Students with high scores on empowerment had high scores on the skill recognition subscale of the Stress Resiliency Profile suggesting more resilience; high scores on empowerment were related to high necessitating subscale scores of the Stress Resiliency Profile suggesting a predisposition to stress. Neuman Systems Model may provide guidance for educators to strengthen student nurses' management of stressors in the workplace. © 2011 Blackwell Publishing Ltd.

2016-01-10

The ACS Division of Nuclear Chemistry and Technology was initiated in 1955 as a subdivision of the Division of Industrial and Engineering Chemistry. Probationary divisional status was lifted in 1965. The Division’s first symposium was held in Denver in 1964 and it is fitting that we kicked-off the 50th Anniversary in Denver in the spring of 2015. Listed as a small ACS Division with only about 1,000 members, NUCL’s impact over the past fifty years has been remarkable. National ACS meetings have had many symposia sponsored or cosponsored by NUCL that included Nobel Laureates, U.S. Senators, other high-ranking officials and many students as speakers. The range of subjects has been exceptional as are the various prestigious awards established by the Division. Of major impact has been the past 30 years of the NUCL Nuclear Chemistry Summer Schools to help fill the void of qualified nuclear scientists and technicians. In celebrating the 50th Anniversary we honor the past, celebrate the present and shape the future of the Division and nuclear science and technology. To celebrate this auspicious occasion a commemorative lapel pin has been designed for distribution to NUCL Division members.

Lead from the center. How to manage divisions dynamically.

Science.gov (United States)

Raynor, M E; Bower, J L

2001-05-01

Conventional wisdom holds that a company's divisions should be given almost total autonomy--especially under conditions of uncertainty--because they are closer to emerging technologies, customers, and competitors than corporate headquarters could ever be. But research from Michael Raynor and Joseph Bower suggests that the corporate office should be more, not less, directive in turbulent markets. Rapid changes in an industry make it difficult to predict where and when synergies among divisions might emerge. With so many possibilities and such uncertainty, companies can't afford to sacrifice their ability to flexibly execute business strategy. Corporate headquarters must play an active role in defining the scope of division-level strategy, the authors say, so that divisions do not act in ways that undermine opportunities to collaborate in the future. But neither can companies afford to sacrifice the competitiveness of their divisions as stand-alone businesses. In creating corporate-level strategic flexibility, a corporate office must balance the need for divisional autonomy now with the potential need for cooperation in the future. Through an examination of four corporations--Sprint, WPP, Teradyne, and Viacom--the authors challenge traditional approaches to diversification in which a company's divisions are either related (they share resources and collaborate) or unrelated (they compete for resources and operate as stand-alone businesses). They argue that companies should adopt a dynamic approach to cooperation among divisions, enabling varying degrees of relatedness between divisions depending on strategic circumstances. The authors offer four tactics to help executives manage divisions dynamically.

Division of labour between different specialized cell types is a central part of how we describe complexity in multicellular organisms. However, it is increasingly being recognized that division of labour also plays an important role in the lives of predominantly unicellular organisms. Saccharomyces cerevisiae displays several phenotypes that could be considered a division of labour, including quiescence, apoptosis and biofilm formation, but they have not been explicitly treated as such. We discuss each of these examples, using a definition of division of labour that involves phenotypic variation between cells within a population, cooperation between cells performing different tasks and maximization of the inclusive fitness of all cells involved. We then propose future research directions and possible experimental tests using S. cerevisiae as a model organism for understanding the genetic mechanisms and selective pressures that can lead to the evolution of the very first stages of a division of labour.

Quantitative regulation of B cell division destiny by signal strength.

Science.gov (United States)

Turner, Marian L; Hawkins, Edwin D; Hodgkin, Philip D

2008-07-01

Differentiation to Ab secreting and isotype-switched effector cells is tightly linked to cell division and therefore the degree of proliferation strongly influences the nature of the immune response. The maximum number of divisions reached, termed the population division destiny, is stochastically distributed in the population and is an important parameter in the quantitative outcome of lymphocyte responses. In this study, we further assessed the variables that regulate B cell division destiny in vitro in response to T cell- and TLR-dependent stimuli. Both the concentration and duration of stimulation were able to regulate the average maximum number of divisions undergone for each stimulus. Notably, a maximum division destiny was reached during provision of repeated saturating stimulation, revealing that an intrinsic limit to proliferation exists even under these conditions. This limit was linked directly to division number rather than time of exposure to stimulation and operated independently of the survival regulation of the cells. These results demonstrate that a B cell population's division destiny is regulable by the stimulatory conditions up to an inherent maximum value. Division destiny is a crucial parameter in regulating the extent of B cell responses and thereby also the nature of the immune response mounted.

The cycle of mitochondrial division and fusion disconnect and reconnect individual mitochondria in cells to remodel this energy-producing organelle. Although dynamin-related protein 1 (Drp1) plays a major role in mitochondrial division in cells, a reduced level of mitochondrial division still persists even in the absence of Drp1. It is unknown how much Drp1-mediated mitochondrial division accounts for the connectivity of mitochondria. The role of a Parkinson’s disease-associated protein—parkin, which biochemically and genetically interacts with Drp1—in mitochondrial connectivity also remains poorly understood. Here, we quantified the number and connectivity of mitochondria using mitochondria-targeted photoactivatable GFP in cells. We show that the loss of Drp1 increases the connectivity of mitochondria by 15-fold in mouse embryonic fibroblasts (MEFs). While a single loss of parkin does not affect the connectivity of mitochondria, the connectivity of mitochondria significantly decreased compared with a single loss of Drp1 when parkin was lost in the absence of Drp1. Furthermore, the loss of parkin decreased the frequency of depolarization of the mitochondrial inner membrane that is caused by increased mitochondrial connectivity in Drp1-knockout MEFs. Therefore, our data suggest that parkin negatively regulates Drp1-indendent mitochondrial division. -- Highlights: •A Drp1-mediated mechanism accounts for ∼95% of mitochondrial division. •Parkin controls the connectivity of mitochondria via a mechanism that is independent of Drp1. •In the absence of Drp1, connected mitochondria transiently depolarize. •The transient depolarization is independent of calcium signaling and uncoupling protein 2.

The cycle of mitochondrial division and fusion disconnect and reconnect individual mitochondria in cells to remodel this energy-producing organelle. Although dynamin-related protein 1 (Drp1) plays a major role in mitochondrial division in cells, a reduced level of mitochondrial division still persists even in the absence of Drp1.

Mapping Urban Social Divisions

Full Text Available Against the background of increased levels of interest in space and images beyond the field of geography, this article (re- introduces earlier work on the semiotics of maps undertaken by geographers in the 1960s. The data limitations, purpose and cultural context in which a user interprets a map's codes and conventions are highlighted in this work, which remains relevant to the interpretation of maps—new and old—forty years later. By means of drawing on geography's contribution to the semiotics of maps, the article goes on to examine the concept of urban social divisions as represented in map images. Using a small number of map images, including two of the most widely known maps of urban social division in Europe and North America, the roles of context, data and purpose in the production and interpretation of maps are discussed. By presenting the examples chronologically the article shows that although advances in data collection and manipulation have allowed researchers to combine different social variables in maps of social division, and to interact with map images, work by geographers on the semiotics of maps is no less relevant today than when it was first proposed forty years ago.

Cancers of the esophagus, stomach, pancreas, liver, and biliary tree have dismal 5-year survival, and very modest improvements in this rate have been made in recent times. Oncolytic viruses are being developed to address these malignancies, with a focus on high safety profiles and low off-target toxicities. Each viral platform has evolved to enhance oncolytic potency and the clinical response to either single-agent viral therapy or combined viral treatment with radiotherapy and chemotherapy. A panel of genomic alterations, chimeric proteins, and pseudotyped capsids are the breakthroughs for vector success. This article revisits developments for each viral platform to each tumor type, in an attempt to achieve maximum tumor selectivity. From the bench to clinical trials, the scope of this review is to highlight the beginnings of translational oncolytic virotherapy research in upper gastrointestinal tract malignancies and provide a bioengineering perspective of the most promising platforms. Keywords: oncolytic viruses, hepatopancreatobiliary, gastric cancer, pancreatic cancer, liver cancer, biliary cancer

Research funded primarily by the NRC is directed toward assessing the roles of cyclic fatigue, intergranular stress corrosion cracking, and irradiation-assisted stress corrosion cracking on failures in light water reactor (LWR) piping systems, pressure vessels, and various core components. In support of the fast reactor program, the Division has responsibility for fuel-performance modeling and irradiation testing. The Division has major responsibilities in several design areas of the proposed International Thermonuclear Experimental Reactor (ITER). The Division supports the DOE in ensuring safe shipment of nuclear materials by providing extensive review of the Safety Analysis Reports for Packaging (SARPs). Finally, in the nuclear area they are investigating the safe disposal of spent fuel and waste. In work funded by DOE's Energy Efficiency and Renewable Energy, the high-temperature superconductivity program continues to be a major focal point for industrial interactions. Coatings and lubricants developed in the division's Tribology Section are intended for use in transportation systems of the future. Continuous fiber ceramic composites are being developed for high-performance heat engines. Nondestructive testing techniques are being developed to evaluate fiber distribution and to detect flaws. A wide variety of coatings for corrosion protection of metal alloys are being studied. These can increase lifetimes significant in a wide variety of coal combustion and gasification environments

Based on the classical time division multi-channel communication theory, we present a scheme of quantum time-division multi-channel communication (QTDMC). Moreover, the model of quantum time division switch (QTDS) and correlative protocol of QTDMC are proposed. The quantum bit error rate (QBER) is analyzed and the QBER simulation test is performed. The scheme shows that the QTDS can carry out multi-user communication through quantum channel, the QBER can also reach the reliability requirement of communication, and the protocol of QTDMC has high practicability and transplantable. The scheme of QTDS may play an important role in the establishment of quantum communication in a large scale in the future. (general)

This paper reviews recent studies of the impact of medical and health humanities coursework in pre-health professions education and describes a pilot study of baccalaureate students who completed semester-long medical humanities courses in the Division of Medical Humanities & Bioethics at the University of Rochester. The study format was an email survey. All participants were current or former baccalaureate students who had taken one or more courses in literature and narrative in medicine, bioethics, history of medicine, and/or visual arts and healthcare during the past four years. The survey gathered numerical data in several areas: demographic information, career plans, self-reported influence of coursework on educational and career plans, and self-reported influence of coursework on intellectual skills and abilities. It also gathered narrative commentary that elaborated on students' responses to the numerically-based questions. Notable findings from preliminary analysis of the data include higher scores of self-reported impact of the coursework on specific habits of mind and on preparedness for intended career rather than on gaining admission to future educational programs. Discussion of the results focuses on several potential future directions this type of study might take, including multi-center, longitudinal, and sequential approaches.

A connection between free and classical infinite divisibility

DEFF Research Database (Denmark)

Barndorff-Nielsen, Ole Eiler; Thorbjørnsen, Steen

2004-01-01

In this paper we continue our studies, initiated in Refs. 2–4, of the connections between the classes of infinitely divisible probability measures in classical and in free probability. We show that the free cumulant transform of any freely infinitely divisible probability measure equals...... the classical cumulant transform of a certain classically infinitely divisible probability measure, and we give several characterizations of the latter measure, including an interpretation in terms of stochastic integration. We find, furthermore, an alternative definition of the Bercovici–Pata bijection, which...

Onset of cell division in maize germination: action of auxins

International Nuclear Information System (INIS)

de Jimenez, E.S.; Baiza, A.; Aguilar, R.

1987-01-01

Seed germination implies metabolic reactivation, synthesis of macromolecules and onset of cell division. During maize germination, meristematic tissues of embryos re-initiate cell division asynchronically. Since auxins are known to stimulate cell division, they asked how auxins might regulate cell cycle re-initiation. Embryonic tissues were incubated with and without auxins. A pulse of either 3 H-thymidine or 32 P-ortophosphate was given to the tissues. Mitotic indexes were determined and % of labeled mitotic cells recorded. Results indicated that meristematic cells re-initiate cell division either from G 1 or G 2 phases. Auxin stimulated differentially the cell division process of these cells. 32 P incorporation into cytoplasmic or nucleic histones was measured. Auxins stimulated this incorporation. Active turnover of histone phosphorylation occurred simultaneously to the cell division process. It is suggested that auxins might regulate the cell cycle by phosphorylation-dephosphorylation of histones

Cell-Division Behavior in a Heterogeneous Swarm Environment.

Science.gov (United States)

Erskine, Adam; Herrmann, J Michael

2015-01-01

We present a system of virtual particles that interact using simple kinetic rules. It is known that heterogeneous mixtures of particles can produce particularly interesting behaviors. Here we present a two-species three-dimensional swarm in which a behavior emerges that resembles cell division. We show that the dividing behavior exists across a narrow but finite band of parameters and for a wide range of population sizes. When executed in a two-dimensional environment the swarm's characteristics and dynamism manifest differently. In further experiments we show that repeated divisions can occur if the system is extended by a biased equilibrium process to control the split of populations. We propose that this repeated division behavior provides a simple model for cell-division mechanisms and is of interest for the formation of morphological structure and to swarm robotics.

High-Fidelity Simulation of Pediatric Emergency Care: An Eye-Opening Experience for Baccalaureate Nursing Students.

Small, Sandra P; Colbourne, Peggy A; Murray, Cynthia L

2018-01-01

Background Little attention has been given to in-depth examination of what high-fidelity simulation is like for nursing students within the context of a pediatric emergency, such as a cardiopulmonary arrest. It is possible that such high-fidelity simulation could provoke in nursing students intense psychological reactions. Purpose The purpose of this study was to learn about baccalaureate nursing students' lived experience of high-fidelity simulation of pediatric cardiopulmonary arrest. Method Phenomenological methods were used. Twenty-four interviews were conducted with 12 students and were analyzed for themes. Results The essence of the experience is that it was eye-opening. The students found the simulation to be a surprisingly realistic nursing experience as reflected in their perceiving the manikin as a real patient, thinking that they were saving their patient's life, feeling like a real nurse, and feeling relief after mounting stress. It was a surprisingly valuable learning experience in that the students had an increased awareness of the art and science of nursing and increased understanding of the importance of teamwork and were feeling more prepared for clinical practice and wanting more simulation experiences. Conclusion Educators should capitalize on the benefits of high-fidelity simulation as a pedagogy, while endeavoring to provide psychologically safe learning.

A review of the literature showed that the core competencies needed by newly graduated Chinese nurses were not as of yet undocumented. To develop a psychometrically sound instrument for identifying and measuring the core competencies needed by Chinese nursing baccalaureate graduates. Descriptive correlational and multicentre study. Seven major tertiary teaching hospitals and three major medical universities in Beijing. 790 subjects, including patients, nursing faculty members, doctors and nurses. A reliable and valid self-report instrument, consisting of 58 items, was developed using multiple methods. It was then distributed to 790 subjects to measure nursing competency in a broader Chinese context. The psychometric characteristics of reliability and validity were supported by descriptive and inferential analyses. The final instrument consists of six dimensions with 47 items. The content validity index was 0.90. The overall scale reliability was 0.97 with dimensions range from 0.87 to 0.94. Six domains of core competencies were identified: professionalism; direct care; support and communication; application of professional knowledge; personal traits; and critical thinking and innovation. The findings of this study provide valuable evidence for a psychometrically sound measurement tool, as well as for competency-based nursing curriculum reform. Copyright © 2013 Elsevier Ltd.

To enhance the Critical Thinking skills of educators associated with the nursing baccalaureate programmes in Pakistan. By focusing on the type and level of questions asked by the educators. Ninety-one faculty members from 14 out of 17 schools participated in the study. Data on the faculty's questioning skills was obtained through classroom observations and field notes. The duration of the observations was 45-60 minutes. Using Bloom's Taxonomy for cognitive thinking, questions were categorised into high and low categories. Most of the questions (68.9 %) asked by the participants were of lower levels, while some (5.37 %) were ambiguous. In many instances, the participants did not allow a sufficient wait-time for students to think and respond. The findings suggest that educators must learn to use the questioning strategy effectively. They should ask higher level questions if they wish to inculcate Critical Thinking in students.

Towers of generalized divisible quantum codes

Science.gov (United States)

Haah, Jeongwan

2018-04-01

A divisible binary classical code is one in which every code word has weight divisible by a fixed integer. If the divisor is 2ν for a positive integer ν , then one can construct a Calderbank-Shor-Steane (CSS) code, where X -stabilizer space is the divisible classical code, that admits a transversal gate in the ν th level of Clifford hierarchy. We consider a generalization of the divisibility by allowing a coefficient vector of odd integers with which every code word has zero dot product modulo the divisor. In this generalized sense, we construct a CSS code with divisor 2ν +1 and code distance d from any CSS code of code distance d and divisor 2ν where the transversal X is a nontrivial logical operator. The encoding rate of the new code is approximately d times smaller than that of the old code. In particular, for large d and ν ≥2 , our construction yields a CSS code of parameters [[O (dν -1) ,Ω (d ) ,d ] ] admitting a transversal gate at the ν th level of Clifford hierarchy. For our construction we introduce a conversion from magic state distillation protocols based on Clifford measurements to those based on codes with transversal T gates. Our tower contains, as a subclass, generalized triply even CSS codes that have appeared in so-called gauge fixing or code switching methods.

1991-06-01

This Annual Report presents summaries of selected representative research activities grouped according to the principal disciplines of the Earth Sciences Division: Reservoir Engineering and Hydrogeology, Geology and Geochemistry, and Geophysics and Geomechanics. Much of the Division`s research deals with the physical and chemical properties and processes in the earth`s crust, from the partially saturated, low-temperature near-surface environment to the high-temperature environments characteristic of regions where magmatic-hydrothermal processes are active. Strengths in laboratory and field instrumentation, numerical modeling, and in situ measurement allow study of the transport of mass and heat through geologic media -- studies that now include the appropriate chemical reactions and the hydraulic-mechanical complexities of fractured rock systems. Of particular note are three major Division efforts addressing problems in the discovery and recovery of petroleum, the application of isotope geochemistry to the study of geodynamic processes and earth history, and the development of borehole methods for high-resolution imaging of the subsurface using seismic and electromagnetic waves. In 1989 a major DOE-wide effort was launched in the areas of Environmental Restoration and Waste Management. Many of the methods previously developed for and applied to deeper regions of the earth will in the coming years be turned toward process definition and characterization of the very shallow subsurface, where man-induced contaminants now intrude and where remedial action is required.

Peptidoglycan architecture can specify division planes in Staphylococcus aureus.

Division in Staphylococci occurs equatorially and on specific sequentially orthogonal planes in three dimensions, resulting, after incomplete cell separation, in the 'bunch of grapes' cluster organization that defines the genus. The shape of Staphylococci is principally maintained by peptidoglycan. In this study, we use Atomic Force Microscopy (AFM) and fluorescence microscopy with vancomycin labelling to examine purified peptidoglycan architecture and its dynamics in Staphylococcus aureus and correlate these with the cell cycle. At the presumptive septum, cells were found to form a large belt of peptidoglycan in the division plane before the centripetal formation of the septal disc; this often had a 'piecrust' texture. After division, the structures remain as orthogonal ribs, encoding the location of past division planes in the cell wall. We propose that this epigenetic information is used to enable S. aureus to divide in sequentially orthogonal planes, explaining how a spherical organism can maintain division plane localization with fidelity over many generations.

Evolutionary dynamics of division of labor games with selfish agents

Science.gov (United States)

Zhang, Jianlei; Li, Qiaoyu; Zhang, Chunyan

2017-11-01

The division of labor is one of the most basic and widely studied aspects of collective behavior in natural systems. Studies of division of labor are concerned with the integration of the individual worker behavior into a colony level task organization and with the question of how the regulation of the division of labor may contribute to the colony efficiency. This paper investigates the evolution of the division of labor with three strategies by employing the evolutionary game theory. Thus, these available strategies are, respectively, strategy A (performing task A), strategy B (performing task B), and strategy D (not performing any task but only free riding others' contributions). And, two typical networks (i.e., BA scale-free network and lattice network) are employed here for describing the interaction structure among agents. The theoretical analysis together with simulation results reveal that the division of labor can evolve and leads to players that differ in their tendency to take on a given task. The conditions under which the division of labor evolves depend on the costs for performing the task, the benefits led by performing the task, and the interaction structures among the players who are involved with division of labor games.

HISTORY OF THE ENGINEERING PHYSICS AND MATHEMATICS DIVISION 1955-1993

2001-09-14

A review of division progress reports noting significant events and findings of the Applied Nuclear Physics, Neutron Physics, Engineering Physics, and then Engineering Physics and Mathematics divisions from 1955 to 1993 was prepared for use in developing a history of the Oak Ridge National Laboratory in celebration of its 50th year. The research resulted in an accumulation of historic material and photographs covering 38 years of effort, and the decision was made to publish a brief history of the division. The history begins with a detailed account of the founding of the Applied Nuclear Physics Division in 1955 and continues through the name change to the Neutron Physics Division in the late 1950s. The material thereafter is presented in decades--the sixties, seventies, and eighties--and ends as we enter the nineties.

Geochemical Identification of Windblown Dust Deposits in the Upper Permian Brushy Canyon Formation, Southern New Mexico

Science.gov (United States)

Tice, M. M.; Motanated, K.; Weiss, R.

2009-12-01

Windblown dust is a potentially important but difficult-to-quantify source of siliciclastics for sedimentary basins worldwide. Positively identifying windblown deposits requires distinguishing them from other low density suspension transport deposits. For instance, laminated very fine grained sandstones and siltstones of the Upper Permian Brushy Canyon Formation have been variously interpreted as 1) the deposits of slow-moving, low-density turbidity currents, 2) distal overbank deposits of turbidity currents, 3) the deposits of turbulent suspensions transported across a pycnocline (interflows), and 4) windblown dust. This facies forms the bulk of Brushy Canyon Formation slope deposits, so understanding its origin is critical to understanding the evolution of the basin as a whole. We use a geochemical mapping technique (x-ray fluorescence microscopy) to show that these rocks are up to two times enriched in very fine sand sized zircon and rutile grains relative to Bouma A divisions of interbedded turbidites, suggesting substantial turbulence during transport. However, in contrast with the A divisions, the laminated sandstones and siltstones never show evidence of scour or amalgamation, implying that flow turbulence did not interact with underlying beds. Moreover, proximal loess deposits are often characterized by elevated Zr/Al2O3. These observations are most consistent with windblown interpretations for Brushy Canyon Formation slope sediments, and suggest that evolution of this early deepwater slope system was controlled largely by short-distance aeolian transport of very fine sand and silt from the coast. Heavy mineral incorporation into Brushy Canyon Formation slope deposits as reflected in laminae-scale bulk Zr and Ti abundances may preserve a long-term record of local wind intensity during the Upper Permian.

A division algebra classification of generalized supersymmetries

Toppan, Francesco

2004-10-01

Generalized supersymmetries admitting bosonic tensor central charges are classified in accordance with their division algebra properties. Division algebra consistent constraints lead (in the complex and quaternionic cases) to the classes of hermitian and holomorphic generalized supersymmetries. Applications to the analytic continuation of the M-algebra to the Euclidean and the systematic investigation of certain classes of models in generic space-times are briefly mentioned. (author)

Cell Division and Evolution of Biological Tissues

Science.gov (United States)

Rivier, Nicolas; Arcenegui-Siemens, Xavier; Schliecker, Gudrun

A tissue is a geometrical, space-filling, random cellular network; it remains in this steady state while individual cells divide. Cell division (fragmentation) is a local, elementary topological transformation which establishes statistical equilibrium of the structure. Statistical equilibrium is characterized by observable relations (Lewis, Aboav) between cell shapes, sizes and those of their neighbours, obtained through maximum entropy and topological correlation extending to nearest neighbours only, i.e. maximal randomness. For a two-dimensional tissue (epithelium), the distribution of cell shapes and that of mother and daughter cells can be obtained from elementary geometrical and physical arguments, except for an exponential factor favouring division of larger cells, and exponential and combinatorial factors encouraging a most symmetric division. The resulting distributions are very narrow, and stationarity severely restricts the range of an adjustable structural parameter

Division of labour and the evolution of extreme specialization.

Science.gov (United States)

Cooper, Guy A; West, Stuart A

2018-05-28

Division of labour is a common feature of social groups, from biofilms to complex animal societies. However, we lack a theoretical framework that can explain why division of labour has evolved on certain branches of the tree of life but not others. Here, we model the division of labour over a cooperative behaviour, considering both when it should evolve and the extent to which the different types should become specialized. We found that: (1) division of labour is usually-but not always-favoured by high efficiency benefits to specialization and low within-group conflict; and (2) natural selection favours extreme specialization, where some individuals are completely dependent on the helping behaviour of others. We make a number of predictions, several of which are supported by the existing empirical data, from microbes and animals, while others suggest novel directions for empirical work. More generally, we show how division of labour can lead to mutual dependence between different individuals and hence drive major evolutionary transitions, such as those to multicellularity and eusociality.

Effects of auxin as plant hormones are widespread; in fact in almost all aspects of plant growth and development auxin plays a pivotal role. Although auxin is required for propagating cell division in plant cells, its effect upon cell division is least understood. If auxin is depleted from the culture medium, cultured cells cease to divide. It has been demonstrated in this context that the addition of auxin to auxin-starved nondividing tobacco BY-2 cells induced semisynchronous cell division. On the other hand, there are some cell lines, named habituated cells, that can grow without auxin. The cause and reason for the habituated cells have not been clarified. A habituated cell line named 2B-13 is derived from the tobacco BY-2 cell line, which has been most intensively studied among plant cell lines. When we tried to find the difference between two cell lines of BY-2 and 2B-13 cells, we found that the addition of culture filtrated from the auxin-habituated 2B-13 cells induced semisynchronous cell division in auxin-starved BY-2 cells. The cell division factor (CDF) that is responsible for inducing cell division in auxin-starved BY-2 cells was purified to near-homogeneity by sequential passage through a hydroxyapatite column, a ConA Sepharose column and a Sephadex gel filtration column. The resulting purified fraction appeared as a single band of high molecular weight on sodium dodecyl sulfate-polyacrylamide gel electrophoresis gels by silver staining and was able to induce cell division in auxin-starved BY-2 cells. Identification of the protein by MALD-TOF-MS/MS revealed that it is structurally related to P-glycoprotein from Gossypioides kirkii, which belongs to ATP-binding cassette (ABC)-transporters. The significance of CDF as a possible ABC-transporter is discussed in relationship to auxin-autotrophic growth and auxin-signaling pathway.

The research activities of the Division at the Petten Establishment have the aims of characterising the properties of high temperature materials in industrial process environments and of understanding the structures involved in order to gain an insight into behavioural mechanisms. Metallic materials fall within the scope of the programme; the activities are, at present, almost entirely concerned with austenitic steels and nickel based alloys. Starting in 1984, advanced ceramic materials will be studied as well. The equipment available permits the study of mechanical properties in controlled gaseous environments, of the rates and mechanisms of corrosive reactions between materials and those environments, and of the surface and bulk structures by advanced physical techniques. Special preparation and treatment techniques are available. The Division has developed a Data Bank on high temperature alloys. It also operates an information Centre, the activities of which include the organisation of scientific meetings, the commissioning of ''state of the art'' studies on topics in the field of high temperature materials and their applications and the development of a inventory of current research activities in the field in Europe. This booklet is intended to present the facilities and services of the Division to the organizations which are interested in its programmes of work

Walsh, Mark S; Waters, Jeff A; Böhm, Harald; Potteiger, Jeff A

The purposes of this study are to examine gender differences in the contribution of the arm swing to jump height in men and women basketball players and to examine the role of upper-body strength in the contribution of arm swing to jump height. National Collegiate Athletic Association Division I basketball players (men n = 13, women n = 12) performed 4 jumping movements: squat jumps with hands on hips (SNA) and with arm swings (SA) and countermovement jumps with hands on hips and with arm swings (CMA). Differences were found between the jump heights of men and women. Use of the arms increased the jump height of men more than women. Compared with the SNA, the SA allowed an increase of 7 cm (23%) for men and 4 cm (17%) for women. The CMA allowed for an increase of 10 cm (30%) for men and 6 cm (24%) for women. General upper-body strength measures did not correlate strongly with the effect of arms on jumping, but peak power did. As in previous studies, peak power had a high correlation with jumping performance. These results show that the arm swing contributes significantly to jump performance in both men and women basketball players and that strength training for jumping should focus on power production and lifting exercises that are jump specific.

Genes involved in cell division in mycoplasmas

Directory of Open Access Journals (Sweden)

2007-01-01

Full Text Available Bacterial cell division has been studied mainly in model systems such as Escherichia coli and Bacillus subtilis, where it is described as a complex process with the participation of a group of proteins which assemble into a multiprotein complex called the septal ring. Mycoplasmas are cell wall-less bacteria presenting a reduced genome. Thus, it was important to compare their genomes to analyze putative genes involved in cell division processes. The division and cell wall (dcw cluster, which in E. coli and B. subtilis is composed of 16 and 17 genes, respectively, is represented by only three to four genes in mycoplasmas. Even the most conserved protein, FtsZ, is not present in all mycoplasma genomes analyzed so far. A model for the FtsZ protein from Mycoplasma hyopneumoniae and Mycoplasma synoviae has been constructed. The conserved residues, essential for GTP/GDP binding, are present in FtsZ from both species. A strong conservation of hydrophobic amino acid patterns is observed, and is probably necessary for the structural stability of the protein when active. M. synoviae FtsZ presents an extended amino acid sequence at the C-terminal portion of the protein, which may participate in interactions with other still unknown proteins crucial for the cell division process.

Reliable and validated assessments of introductory physics have been instrumental in driving curricular and pedagogical reforms that lead to improved student learning. As part of an effort to systematically improve our sophomore-level classical mechanics and math methods course (CM 1) at CU Boulder, we have developed a tool to assess student learning of CM 1 concepts in the upper division. The Colorado Classical Mechanics and Math Methods Instrument (CCMI) builds on faculty consensus learning goals and systematic observations of student difficulties. The result is a 9-question open-ended post test that probes student learning in the first half of a two-semester classical mechanics and math methods sequence. In this paper, we describe the design and development of this instrument, its validation, and measurements made in classes at CU Boulder and elsewhere.

Tumors located in the upper/upper inner quadrant of the breast warrant more attention. A small lesion relative to the size of breast in this location may be resolved by performing a level I oncoplastic technique. However, a wide excision may significantly reduce the overall quality of the breast shape by distorting the visible breast line. From June 2012 to April 2015, 36 patients with breast cancer located in the upper/upper inner quadrant underwent breast-conservation surgery with matrix rotation mammoplasty. According to the size and location of the tumor relative to the nipple-areola complex, 11 patients underwent matrix rotation with periareolar de-epithelialization (donut group) and the other 25 underwent matrix rotation only (non-donut group). The cosmetic results were self-assessed by questionnaires. The average weights of the excised breast lumps in the donut and non-donut groups were 104.1 and 84.5 g, respectively. During the 3-year follow-up period, local recurrence was observed in one case and was managed with nipple-sparing mastectomy followed by breast reconstruction with prosthetic implants. In total, 31 patients (88.6%) ranked their postoperative result as either acceptable or satisfactory. The treated breasts were also self-evaluated by 27 patients (77.1%) to be nearly identical to or just slightly different from the untreated side. Matrix rotation is an easy breast-preserving technique for treating breast cancer located in the upper/upper inner quadrant of the breast that requires a relatively wide excision. With this technique, a larger breast tumor could be removed without compromising the breast appearance.

Full Text Available This design research aims to develop a learning activity which supports the fifth-grade students to understand measurement fraction division problems (A whole number divided by a fraction that result in a whole number answer conceptually. Furthermore, how students solve the fraction division problem using models is also analyzed.  Data for the retrospective analysis is collected through two teaching experiments in the form of students’ work, field notes, and some part of classroom discussions. The important findings in this research are: 1 the developed learning activity namely Motivation Cards support students understand that  3 divided by one-half means how many one-half are in 3 through models. However, when the divisor is not a unit fraction they could not directly relate the unshaded part in area model for example. 2 area model is proper model to be firstly introduced when the students work on fraction division. 3 understanding this kind of fraction division help students understand other measurement fraction division where both divisor and dividend are fractions. 4 the learning activity supports the development of character values for students.    

Student learning of upper-level thermal and statistical physics: The derivation and use of the Boltzmann factor

Science.gov (United States)

Thompson, John

2015-04-01

As the Physical Review Focused Collection demonstrates, recent frontiers in physics education research include systematic investigations at the upper division. As part of a collaborative project, we have examined student understanding of several topics in upper-division thermal and statistical physics. A fruitful context for research is the Boltzmann factor in statistical mechanics: the standard derivation involves several physically justified mathematical steps as well as the invocation of a Taylor series expansion. We have investigated student understanding of the physical significance of the Boltzmann factor as well as its utility in various circumstances, and identified various lines of student reasoning related to the use of the Boltzmann factor. Results from written data as well as teaching interviews suggest that many students do not use the Boltzmann factor when answering questions related to probability in applicable physical situations, even after lecture instruction. We designed an inquiry-based tutorial activity to guide students through a derivation of the Boltzmann factor and to encourage deep connections between the physical quantities involved and the mathematics. Observations of students working through the tutorial suggest that many students at this level can recognize and interpret Taylor series expansions, but they often lack fluency in creating and using Taylor series appropriately, despite previous exposure in both calculus and physics courses. Our findings also suggest that tutorial participation not only increases the prevalence of relevant invocation of the Boltzmann factor, but also helps students gain an appreciation of the physical implications and meaning of the mathematical formalism behind the formula.

Wavefront division digital holography

Zhang, Wenhui; Cao, Liangcai; Li, Rujia; Zhang, Hua; Zhang, Hao; Jiang, Qiang; Jin, Guofan

2018-05-01

Digital holography (DH), mostly Mach-Zehnder configuration based, belongs to non-common path amplitude splitting interference imaging whose stability and fringe contrast are environmental sensitive. This paper presents a wavefront division DH configuration with both high stability and high-contrast fringes benefitting from quasi common path wavefront-splitting interference. In our proposal, two spherical waves with similar curvature coming from the same wavefront are used, which makes full use of the physical sampling capacity of the detectors. The interference fringe spacing can be adjusted flexibly for both in-line and off-axis mode due to the independent modulation to these two waves. Only a few optical elements, including the mirror-beam splitter interference component, are used without strict alignments, which makes it robust and easy-to-implement. The proposed wavefront division DH promotes interference imaging physics into the practical and miniaturized a step forward. The feasibility of this method is proved by the imaging of a resolution target and a water flea.

Introduction. Mentoring relationships have been shown to support academicians in areas of research, work/life balance, and promotion. Methods. General pediatric division chiefs accessed an electronic survey asking about mentorship relationships, their ability to create a mentorship program, and resources needed. Results. Dyadic mentorship programs were available at 53% of divisions. Peer mentorship programs were available at 27% of divisions. Overall, 84% of chiefs believed that dyadic mentorship would benefit their faculty. 91% of chiefs believed that peer mentorship would benefit their faculty. Chiefs were interested in starting peer (57%) or dyadic (55%) mentorship programs. Few divisions had a peer mentorship program available, whereas 24% already had a dyadic program. 43% of chiefs felt that they had the tools to start a program. Many tools are needed to create a program. Discussion. General pediatric division chiefs acknowledge the benefits of mentoring relationships, and some have programs in place. Many need tools to create them. Pediatric societies could facilitate this critical area of professional development.

Stationary Size Distributions of Growing Cells with Binary and Multiple Cell Division

Science.gov (United States)

Rading, M. M.; Engel, T. A.; Lipowsky, R.; Valleriani, A.

2011-10-01

Populations of unicellular organisms that grow under constant environmental conditions are considered theoretically. The size distribution of these cells is calculated analytically, both for the usual process of binary division, in which one mother cell produces always two daughter cells, and for the more complex process of multiple division, in which one mother cell can produce 2 n daughter cells with n=1,2,3,… . The latter mode of division is inspired by the unicellular algae Chlamydomonas reinhardtii. The uniform response of the whole population to different environmental conditions is encoded in the individual rates of growth and division of the cells. The analytical treatment of the problem is based on size-dependent rules for cell growth and stochastic transition processes for cell division. The comparison between binary and multiple division shows that these different division processes lead to qualitatively different results for the size distribution and the population growth rates.

Li, Yupeng; Ding, Ding

2017-09-01

Benefiting from the high spectral efficiency and low peak-to-average power ratio, constant envelope orthogonal frequency division multiplexing (OFDM) is a promising technique in coherent optical communication. Polarization-division multiplexing (PDM) has been employed as an effective way to double the transmission capacity in the commercial 100 Gb/s PDM-QPSK system. We investigated constant envelope OFDM together with PDM. Simulation results show that the acceptable maximum launch power into the fiber improves 10 and 6 dB for 80- and 320-km transmission, respectively (compared with the conventional PDM OFDM system). The maximum reachable distance of the constant envelope OFDM system is able to reach 800 km, and even 1200 km is reachable if an ideal erbium doped fiber amplifier is employed.

Directory of Open Access Journals (Sweden)

Joseph Lin

Full Text Available Tumors located in the upper/upper inner quadrant of the breast warrant more attention. A small lesion relative to the size of breast in this location may be resolved by performing a level I oncoplastic technique. However, a wide excision may significantly reduce the overall quality of the breast shape by distorting the visible breast line. From June 2012 to April 2015, 36 patients with breast cancer located in the upper/upper inner quadrant underwent breast-conservation surgery with matrix rotation mammoplasty. According to the size and location of the tumor relative to the nipple-areola complex, 11 patients underwent matrix rotation with periareolar de-epithelialization (donut group and the other 25 underwent matrix rotation only (non-donut group. The cosmetic results were self-assessed by questionnaires. The average weights of the excised breast lumps in the donut and non-donut groups were 104.1 and 84.5 g, respectively. During the 3-year follow-up period, local recurrence was observed in one case and was managed with nipple-sparing mastectomy followed by breast reconstruction with prosthetic implants. In total, 31 patients (88.6% ranked their postoperative result as either acceptable or satisfactory. The treated breasts were also self-evaluated by 27 patients (77.1% to be nearly identical to or just slightly different from the untreated side. Matrix rotation is an easy breast-preserving technique for treating breast cancer located in the upper/upper inner quadrant of the breast that requires a relatively wide excision. With this technique, a larger breast tumor could be removed without compromising the breast appearance.

1984-08-01

This report summarizes the research performed in the Physics, Computer Science and Mathematics Division of the Lawrence Berkeley Laboratory during calendar year 1983. The major activity of the Division is research in high-energy physics, both experimental and theoretical, and research and development in associated technologies. A smaller, but still significant, program is in computer science and applied mathematics. During 1983 there were approximately 160 people in the Division active in or supporting high-energy physics research, including about 40 graduate students. In computer science and mathematics, the total staff, including students and faculty, was roughly 50. Because of the creation in late 1983 of a Computing Division at LBL and the transfer of the Computer Science activities to the new Division, this annual report is the last from the Physics, Computer Science and Mathematics Division. In December 1983 the Division reverted to its historic name, the Physics Division. Its future annual reports will document high energy physics activities and also those of its Mathematics Department.

Krol, Mark F.; Boncek, Raymond K.; Johns, Steven T.; Stacy, John L.

1991-12-01

This report describes the development of an optical Time-Division Multiple-Access (TDMA) interconnect suitable for applications in local-area and micro-area networks. The advantages of using time-division techniques instead of frequency-division, wavelength-division, or code-division techniques in a shared-medium environment are discussed in detail. Furthermore, a detailed description of the TDMA architecture is presented along with various experiments pertaining to the actual components needed to implement the system. Finally, experimental data is presented for an actual optical TDMA test bed. The experimental data demonstrates the feasibility of the architecture, and shows that currently the system has the capability to accommodate up to 50 channels. The bit-error-rate per channel was measured to be less than 10(exp -9) for pseudo-random bit-sequences.

Bribe-proof Rules in the Division Problem

OpenAIRE

Jordi MassóAuthor-Email:; Alejandro Neme

2003-01-01

The division problem consists of allocating an amount of a perfectly divisible good among a group of n agents with single-peaked preferences. A rule maps preference profiles into n shares of the amount to be allocated. A rule is bribe-proof if no group of agents can compensate another agent to misrepresent his preference and, after an appropriate redistribution of their shares, each obtain a strictly preferred share. We characterize all bribe-proof rules as the class of efficient, strategy-pr...

Its goals and accomplishments are described in this annual progress report for FY 1992. Energy Division`s total expenditures in FY 1992 were $42.8 million. The work is supported by the US Department of Energy, the US Department of Defense, many other federal agencies, and some private organizations. Disciplines of the 116.5 technical staff members include engineering, social sciences, physical and life sciences, and mathematics and statistics. The division`s programmatic activities cover three main areas: (1) analysis and assessment, (2) energy conservation technologies, and (3) military transportation systems. Analysis and assessment activities involve energy and resource analysis, preparation of environmental assessments and impact statements, research on waste management, technology transfer, analysis of energy and environmental needs in developing countries, and civilian transportation analysis. Energy conservation technologies focus on electric power systems, building envelopes (walls, foundations, roofs, attics, and materials), and methods to improve energy efficiency in existing buildings. Military transportation systems conduct research for sponsors within the US military to improve the efficiency of military deployment, scheduling, and transportation coordination. Much of Energy Division`s research is valuable to other organizations as well as to sponsors. This information is disseminated by the staff`s involvement in professional and trade organizations and workshops; joint research with universities and private-sector firms; collaboration with state and local governments; presentation of work at conferences; and publication of research results in journals, reports, and conference proceedings.

On the interrelation of multiplication and division in secondary school children

Directory of Open Access Journals (Sweden)

Stefan eHuber

2013-10-01

Full Text Available Multiplication and division are conceptually inversely related: Each division problem can be transformed into as a multiplication problem and vice versa. Recent research has indicated strong developmental parallels between multiplication and division in primary school children. In this study, we were interested in (i whether these developmental parallels persist into secondary school, (ii whether similar developmental parallels can be observed for simple and complex problems, (iii whether skill level modulates this relationship, and (iv whether the correlations are specific and not driven by general cognitive or arithmetic abilities.Therefore, we assessed performance of 5th and 6th graders attending two secondary school types of the German educational system in simple and complex multiplication as well as division while controlling for nonverbal intelligence, short-term memory, and other arithmetic abilities. Accordingly, we collected data from students differing in skills levels due to either age (5th and 6th grade or school type (general and intermediate secondary school.We observed moderate to strong bivariate and partial correlations between multiplication and division with correlations being higher for simple tasks but nevertheless reliable for complex tasks. Moreover, the association between simple multiplication and division depended on students’ skill levels as reflected by school types, but not by age. Partial correlations were higher for intermediate than for general secondary school children.In sum, these findings emphasize the importance of the inverse relationship between multiplication and division which persists into later developmental stages. However, evidence for skill-related differences in the relationship between multiplication and division was restricted to the differences for school types.

2017-04-01

Full Text Available Reliable and validated assessments of introductory physics have been instrumental in driving curricular and pedagogical reforms that lead to improved student learning. As part of an effort to systematically improve our sophomore-level classical mechanics and math methods course (CM 1 at CU Boulder, we have developed a tool to assess student learning of CM 1 concepts in the upper division. The Colorado Classical Mechanics and Math Methods Instrument (CCMI builds on faculty consensus learning goals and systematic observations of student difficulties. The result is a 9-question open-ended post test that probes student learning in the first half of a two-semester classical mechanics and math methods sequence. In this paper, we describe the design and development of this instrument, its validation, and measurements made in classes at CU Boulder and elsewhere.

Wade, C [comp.

1992-01-01

The primary responsibility of the Health, Safety, and Environmental (HSE) Division at the Los Alamos National Laboratory is to provide comprehensive occupational health and safety programs, waste processing, and environmental protection. These activities are designed to protect the worker, the public, and the environment. Meeting these responsibilities requires expertise in many disciplines, including radiation protection, industrial hygiene, safety, occupational medicine, environmental science and engineering, analytical chemistry, epidemiology, and waste management. New and challenging health, safety, and environmental problems occasionally arise from the diverse research and development work of the Laboratory, and research programs in HSE Division often stem from these applied needs. These programs continue but are also extended, as needed, to study specific problems for the Department of Energy. The results of these programs help develop better practices in occupational health and safety, radiation protection, and environmental science.

The Chemical Technology Division (CMT) is one of eight engineering research divisions within Argonne National Laboratory, one of the U.S. government's oldest and largest research laboratories. The University of Chicago oversees the laboratory on behalf of the U.S. Department of Energy (DOE). Argonne's mission is to conduct basic scientific research, to operate national scientific facilities, to enhance the nation's energy resources, and to develop better ways to manage environmental problems. Argonne has the further responsibility of strengthening the nation's technology base by developing innovative technology and transferring it to industry. CMT is a diverse early-stage engineering organization, specializing in the treatment of spent nuclear fuel, development of advanced electrochemical power sources, and management of both high- and low-level nuclear wastes. Although this work is often indistinguishable from basic research, our efforts are directed toward the practical devices and processes that are covered by Argonne's mission. Additionally, the Division operates the Analytical Chemistry Laboratory and Environment, Safety, and Health Analytical Chemistry services, which provide a broad range of analytical services to Argonne and other organizations. The Division is multidisciplinary. Its people have formal training as ceramists; physicists; material scientists; electrical, mechanical, chemical, and nuclear engineers; and chemists. They have experience working in academia; urban planning; and the petroleum, aluminum, and automotive industries. Their skills include catalysis, ceramics, electrochemistry, metallurgy, nuclear magnetic resonance spectroscopy, and petroleum refining, as well as the development of nuclear waste forms, batteries, and high-temperature superconductors

The ANL Physics Division traces its roots to nuclear physics research at the University of Chicago around the time of the second world war. Following the move from the University of Chicago out to the present Argonne site and the formation of Argonne National Laboratory: the Physics Division has had a tradition of research into fundamental aspects of nuclear and atomic physics. Initially, the emphasis was on areas such as neutron physics, mass spectrometry, and theoretical studies of the nuclear shell model. Maria Goeppert Maier was an employee in the Physics Division during the time she did her Nobel-Prize-winning work on the nuclear shell model. These interests diversified and at the present time the research addresses a wide range of current problems in nuclear and atomic physics. The major emphasis of the current experimental nuclear physics research is in heavy-ion physics, centered around the ATLAS facility (Argonne Tandem-Linac Accelerator System) with its new injector providing intense, energetic ion beams over the fill mass range up to uranium. ATLAS is a designated National User Facility and is based on superconducting radio-frequency technology developed in the Physics Division. A small program continues in accelerator development. In addition, the Division has a strong program in medium-energy nuclear physics carried out at a variety of major national and international facilities. The nuclear theory research in the Division spans a wide range of interests including nuclear dynamics with subnucleonic degrees of freedom, dynamics of many-nucleon systems, nuclear structure, and heavy-ion interactions. This research makes contact with experimental research programs in intermediate-energy and heavy-ion physics, both within the Division and on the national and international scale. The Physics Division traditionally has strong connections with the nation's universities. We have many visiting faculty members and we encourage students to participate in our

One of 17 research divisions at Oak Ridge National Laboratory, Energy Division`s mission is to provide innovative solutions to energy and related issues of national and global importance through interdisciplinary research and development. Its goals and accomplishments are described in this annual progress report for FY1993. Energy Division is committed to (1) understanding the mechanisms by which societies make choices in energy use; (2) improving society`s understanding of the environmental, social, and economic implications of technological change; (3) developing and transferring energy-efficient technologies; (4) improving transportation policy and planning; (5) enhancing basic knowledge in the social sciences as related to energy and associated issues. Energy Division`s expenditures in FY1993 totaled $42 million. The work was supported by the US DOE, DOD, many other federal agencies, and some private organizations. Disciplines of the 126.5 technical staff members include engineering, social sciences, physical and life sciences, and computer sciences and data systems. The division`s programmatic activities cover three main areas: (1) analysis and assessment, (2) energy use and delivery technologies, and (3) transportation systems. Analysis and assessment activities involve energy and resource analysis, preparation of environmental assessments and impact statements, research on emergency preparedness, transportation analysis, and analysis of energy and environmental needs in developing countries. Energy use and delivery technologies focus on electric power systems, building equipment, building envelopes (walls, foundations, roofs, attics, and materials), and methods to improve energy efficiency in existing buildings. Transportation systems research is conducted both to improve the quality of civilian transportation and for sponsors within the US military to improve the efficiency of deployment, scheduling, and transportation coordination.

The aim of this retrospective study was to analyse and compare the post-treatment occlusal changes of Class II division 2 treatment with the Herbst appliance in early adolescent, late adolescent, and adult subjects. The subjects were 37 Class II division 2 patients (19 females and 18 males) treated at the Orthodontic Department, University of Giessen, Germany. All were in the late mixed or permanent dentition and exhibited a Class II molar relationship > or =0.5 cusp width (CW) bilaterally or > or =1.0 CW unilaterally, an overbite (OB) >3.0 mm, and two upper central incisors retroclined. The subjects were divided into three skeletal maturity groups based on evaluation of hand wrist radiographs: early adolescent (n = 10, stages MP3-E to MP3-FG at start of treatment, age range: 11.3-13.2 years), late adolescent (n = 14, stages MP3-G to MP3-I at start of treatment, age range: 14.1-16.4 years), and adult (n = 13, stages R-I to R-J at the start of treatment, age range: 16.3-25.6 years). Study casts from before treatment (T1), after Herbst-Tip-Edge-Multibracket appliance treatment (T2), and after an average retention time of 27 months (T3) were analysed. Statistical analysis was undertaken using t-tests for paired and unpaired samples. For the whole sample, the molar relationship at T3 was stable in 82.4 per cent, the canine relationship in 82.9 per cent, and OB in 75.7 per cent of the cases. In the different skeletal maturity groups, the stability of the molars, canines, and overbite was as follows: early adolescents: 95.0, 100.0, and 70.0 per cent, respectively; late adolescents: 92.9, 74.1, and 85.7 per cent, respectively; and adults 61.5, 80.8, 69.2 per cent, respectively. Occlusal correction of Class II division 2 malocclusions with Herbst treatment was relatively stable 2 years post-treatment. The outcome of treatment of adolescents was more stable than that of adults.

This study examines the prevalence of depression, anxiety and symptoms of stress among baccalaureate nursing students in Hong Kong. Recent epidemiological data suggest that the prevalence of mild to severe depression, anxiety and stress among qualified nurses in Hong Kong stands at 35.8%, 37.3% and 41.1%, respectively. A total of 661 nursing students were recruited to participate in our cross-sectional mental health survey using the Depression, Anxiety and Stress Scale 21. Multiple logistic regression was used to determine significant relationships between variables. Working in general medicine, being in financial difficulty, having sleep problems, not having leisure activity and perceiving oneself in poor mental health were significant correlates of past-week depression, anxiety and stress. Year of study, physical inactivity and family crisis in the past year correlated significantly with depression. Imbalanced diets significantly correlated with anxiety. Stress was significantly associated with a lack of alone time. This is the first study to confirm empirically that clinical specialty, financial difficulties and lifestyle factors can increase nursing students' levels of depression and anxiety and symptoms of stress. Prevention, including the early detection and treatment of mental disorder, promises to reduce the prevalence of these indicators among this group.

In 1970, when the Solar Physics Division was established, the invitation to become a founding member of the Division was extended by the Organizing Committee to a group of 61 solar scientists of which 4 were women (6.6%). At the first SPD meeting in Huntsville AL (1970), 11% of the papers were given by women. Near that time (1973), women accounted for 8% of all AAS members. The representation of women in the SPD has more than doubled in percentage since the first years. Currently, women comprise about 15.5% of SPD members which, however, is less than the percentage in the AAS general membership (18%) in March 2007. In the 37 years that the SPD has existed, women have frequently held the office of Treasurer and Secretary of the Division and made notable contributions. Elske V.P. Smith was elected the first Treasurer of the SPD and that began a long tradition. Women appear to be considered exceptionally trustworthy since they have been reelected and occupied the position of Treasurer for 75% of the available terms. The Office of SPD Secretary has seen a woman for 13% of the terms. Yet women are practically absent among those in the top leadership positions and in the lists of prize winners of the SPD. Among the 21 SPD Chairs, only 1 woman, Judith T. Karpen, has held that office. The Hale Prize has been awarded 19 times in almost 3 decades, and all of the awardees have been men. Several aspects of the participation of women and their contributions to the Solar Physics Division of the AAS will be reviewed, and compared to that of the AAS and astronomy in general.

The division of labor is an important component of the organization of human society. However, why this division evolved in hominids requires further investigation. Archeological evidence suggests that it appeared after the emergence of Homo sapiens and contributed to the great success of our species. We develop a mathematical model to investigate under what conditions division of labor should evolve. We assume two types of resources the acquisition of which demands different skills, and study the evolution of the strategy that an individual should use to divide its lifetime into learning and using each skill. We show that division of labor likely evolves when group size is large, skill learning is important for acquiring resources, and there is food sharing within a group. We also investigate division of labor by gender under the assumption that the genders have different efficiencies in acquiring each resource. We show that division of labor by gender likely evolves when skill learning is important and the difference in efficiencies between genders in acquiring resources is large. We discuss how the results of our analysis might apply to the evolution of division of labor in hominids. Copyright © 2014 Elsevier Ltd. All rights reserved.

Today's students are the nurses of tomorrow. They need appropriate clinical learning opportunities in order to shape their professional identity, attitudes and values. Despite undeniable progresses of nursing education in Iran, the quality of the clinical education in Iran is not favorable. There is a need to explore the environment of clinical baccalaureate nursing students' education for developing, maintaining and enhancing the quality of clinical program. This is a qualitative study and was conducted based on content analysis multimethod design. Data were collected by individual interviews, focus groups and direct observations. 54 nursing students and 8 clinical educators from the four geographically diverse universities in the Iran composed the study sample. A purposive sampling was used. Five themes were emerged from data analysis including; ambiguity in the nursing care role, routine-based nursing care, uncritical and dependent thinking climate, incompetency of clinical educators and patient education as important component of nursing. The findings of this study describe a clearer understanding of the real environment of the clinical education in Iran. All of themes that emerged from the study play an important role in student learning and nursing education. It is crucial to pay more attention to reconsider care concept as an operational component of nursing, maximize meaningful learning opportunities, reevaluate clinical instructor as role models and prepare effective operational plan to combine theoretical and evidence based knowledge with clinical practice.

Characterization of dependencies between growth and division in budding yeast.

Cell growth and division are processes vital to the proliferation and development of life. Coordination between these two processes has been recognized for decades in a variety of organisms. In the budding yeast Saccharomyces cerevisiae , this coordination or 'size control' appears as an inverse correlation between cell size and the rate of cell-cycle progression, routinely observed in G 1 prior to cell division commitment. Beyond this point, cells are presumed to complete S/G 2 /M at similar rates and in a size-independent manner. As such, studies of dependence between growth and division have focused on G 1 Moreover, in unicellular organisms, coordination between growth and division has commonly been analysed within the cycle of a single cell without accounting for correlations in growth and division characteristics between cycles of related cells. In a comprehensive analysis of three published time-lapse microscopy datasets, we analyse both intra- and inter-cycle dependencies between growth and division, revisiting assumptions about the coordination between these two processes. Interestingly, we find evidence (i) that S/G 2 /M durations are systematically longer in daughters than in mothers, (ii) of dependencies between S/G 2 /M and size at budding that echo the classical G 1 dependencies, and (iii) in contrast with recent bacterial studies, of negative dependencies between size at birth and size accumulated during the cell cycle. In addition, we develop a novel hierarchical model to uncover inter-cycle dependencies, and we find evidence for such dependencies in cells growing in sugar-poor environments. Our analysis highlights the need for experimentalists and modellers to account for new sources of cell-to-cell variation in growth and division, and our model provides a formal statistical framework for the continued study of dependencies between biological processes. © 2017 The Author(s).

The cell division cycle 20, a key component of spindle assembly checkpoint, is an essential activator of the anaphase-promoting complex. Aberrant expression of cell division cycle 20 has been detected in various human cancers. However, its clinical significance has never been deeply investigated in non-small-cell lung cancer. By analyzing The Cancer Genome Atlas database and using some certain online databases, we validated overexpression of cell division cycle 20 in both messenger RNA and protein levels, explored its clinical significance, and evaluated the prognostic role of cell division cycle 20 in non-small-cell lung cancer. Cell division cycle 20 expression was significantly correlated with sex (p = 0.003), histological classification (p overexpression of cell division cycle 20 was significantly associated with bigger primary tumor size (p = 0.0023), higher MKI67 level (r = 0.7618, p Overexpression of cell division cycle 20 is associated with poor prognosis in lung adenocarcinoma patients, and its overexpression can also be used to identify high-risk groups. In conclusion, cell division cycle 20 might serve as a potential biomarker for lung adenocarcinoma patients.

Uncovering the link between malfunctions in Drosophila neuroblast asymmetric cell division and tumorigenesis

Directory of Open Access Journals (Sweden)

Kelsom Corey

2012-11-01

Full Text Available Abstract Asymmetric cell division is a developmental process utilized by several organisms. On the most basic level, an asymmetric division produces two daughter cells, each possessing a different identity or fate. Drosophila melanogaster progenitor cells, referred to as neuroblasts, undergo asymmetric division to produce a daughter neuroblast and another cell known as a ganglion mother cell (GMC. There are several features of asymmetric division in Drosophila that make it a very complex process, and these aspects will be discussed at length. The cell fate determinants that play a role in specifying daughter cell fate, as well as the mechanisms behind setting up cortical polarity within neuroblasts, have proved to be essential to ensuring that neurogenesis occurs properly. The role that mitotic spindle orientation plays in coordinating asymmetric division, as well as how cell cycle regulators influence asymmetric division machinery, will also be addressed. Most significantly, malfunctions during asymmetric cell division have shown to be causally linked with neoplastic growth and tumor formation. Therefore, it is imperative that the developmental repercussions as a result of asymmetric cell division gone awry be understood.

Human blood from normal donors was irradiated with 200 R during the G/sub 0/ phase, and the X-ray sensitivity of early and late dividing lymphocytes in culture was expressed as percentage of induced dicentrics. Cells in first or subsequent divisions were individualized by BrdU-Giemsa techniques. Lymphocytes in the first division at 40, 44 and 72 h after the start of culture had a lower sensitivity to radiation than lymphocytes making their first division at 48, 52 and 56 h. It was observed that: (a) the combination of radiation followed by BrdU did not increase the clastoyenic action of X-rays, (b)X-rays in the dose and duration used in our cultures did not increase the frequency of SCEs, and (c) minor changes in culture conditions probably influenced the frequency of SCEs.

2015-08-01

Full Text Available Background Research to date has investigated the potential factors that influence students’ decisions in opting to study certain subjects during their upper secondary education. Trends in subject selection at this level (Key Stage 4 have been maintained over time and have consistently displayed comparable differences for males and females. It is recognised that males typically opt for subjects such as physical education and science, while females are traditionally noted as favouring the arts and humanities. These educational decisions may impact on future occupational directions. In light of recent initiatives, such as the English Baccalaureate, it is of interest to explore whether such measures have had an influence on this noted gender gap. Participants and procedure The present study investigates the potential predictors of subject selection, while controlling for gender, offering a specific focus on the education system in England. Attention is given to students’ perceived academic ability and attitude toward school, and how such factors may guide subject choice. Participants (N = 276 were students currently in the process of selecting optional modules for Key Stage 4 study. Results The findings demonstrate that female students are less likely than their male counterparts to opt for physical education (PE and business studies/information and communication technology (ICT as preferred modules, in comparison to ‘creative and performance’ subjects (reference category. Higher levels of reported masculinity were also shown to relate to the up-take of PE at Key Stage 4. Conclusions The implications of these findings are discussed in relation to existing research and practical contributions to the educational arena.

PDV2 has a dosage effect on chloroplast division in Arabidopsis thaliana , but this effect may vary in different plants. Chloroplasts have to be divided as plants grow to maintain an optimized number in the cell. Chloroplasts are divided by protein complexes across the double membranes from the stroma side to the cytosolic side. PDV2 is a chloroplast division protein on the chloroplast outer membrane. It recruits the dynamin-related GTPase ARC5 to the division site. The C-terminus of PDV2 and the C-terminus of ARC6 interact in the intermembrane space, which is important for the localization of PDV2. Previously, it was shown that overexpression of PDV2 can increase the division of chloroplasts in Arabidopsis and moss, so the authors concluded that PDV2 determines the rate of chloroplast division in land plants. PDV2 was also shown to inhibit the GTPase activity of ARC5 by in vitro experiment. These results look to be contradictory. Here, we identified a null allele of PDV2 in Arabidopsis and studied plants with different levels of PDV2. Our results suggested that the chloroplast division phenotype in Arabidopsis is sensitive to the level of PDV2, while this is not the case for ARC6. The level of PDV2 protein is reduced sharply in fast-growing leaves, while the level of ARC6 is not. The levels of PDV2 and ARC6 in several other plant species at different developmental stages were also investigated. The results indicated that their expression pattern varies in different species. Thus, PDV2 is an important positive factor of chloroplast division with an apparent dosage effect in Arabidopsis, but this effect for different chloroplast division proteins in different plants may vary.

Growth-arrest-specific protein 2 inhibits cell division in Xenopus embryos.

Directory of Open Access Journals (Sweden)

Tong Zhang

Full Text Available Growth-arrest-specific 2 gene was originally identified in murine fibroblasts under growth arrest conditions. Furthermore, serum stimulation of quiescent, non-dividing cells leads to the down-regulation of gas2 and results in re-entry into the cell cycle. Cytoskeleton rearrangements are critical for cell cycle progression and cell division and the Gas2 protein has been shown to co-localize with actin and microtubules in interphase mammalian cells. Despite these findings, direct evidence supporting a role for Gas2 in the mechanism of cell division has not been reported.To determine whether the Gas2 protein plays a role in cell division, we over-expressed the full-length Gas2 protein and Gas2 truncations containing either the actin-binding CH domain or the tubulin-binding Gas2 domain in Xenopus laevis embryos. We found that both the full-length Gas2 protein and the Gas2 domain, but not the CH domain, inhibited cell division and resulted in multinucleated cells. The observation that Gas2 domain alone can arrest cell division suggests that Gas2 function is mediated by microtubule binding. Gas2 co-localized with microtubules at the cell cortex of Gas2-injected Xenopus embryos using cryo-confocal microscopy and co-sedimented with microtubules in cytoskeleton co-sedimentation assays. To investigate the mechanism of Gas2-induced cell division arrest, we showed, using a wound-induced contractile array assay, that Gas2 stabilized microtubules. Finally, electron microscopy studies demonstrated that Gas2 bundled microtubules into higher-order structures.Our experiments show that Gas2 inhibits cell division in Xenopus embryos. We propose that Gas2 function is mediated by binding and bundling microtubules, leading to cell division arrest.

It has become apparent that bacteria possess ancestors of the major eukaryotic cytoskeletal proteins. FtsZ, the ancestral homologue of tubulin, assembles into a cytoskeletal structure associated with cell division, designated the Z ring. Formation of the Z ring represents a major point of both spatial and temporal regulation of cell division. Here we discuss findings concerning the structure and the formation of the ring as well as its spatial and temporal regulation.

New graduate nurses' (NGNs) transition into the nursing workforce is characterized as stressful and challenging. Consequently, a high percentage of them leave their first place of employment or the profession entirely within one year of graduation. Nursing literature describes this complicated shift from student to registered nurse, however, limited attention has focused on strategies that could be implemented during students' academic programs to prepare them for this difficult transition period. Therefore, a longitudinal intervention study was conducted to examine the influence of a career planning and development (CPD) program on the development of career resilience in baccalaureate nursing students and at 12 months post-graduation (NGN). The findings support including structured and progressive curriculum-based CPD opportunities in academic programs, not only for the positive outcomes that accrue to students, but also because of the benefits they extend to NGNs as they make the transition to their first professional nursing role.

Full Text Available Background The prevalence of stunting in Indonesia is high, with particularly negative impacts on health during childhood as well as adolescence. Stunting impacts the health of children as well as adults, especially with  regards to future obesity. Therefore, evaluating body composition of stunted children before 2 years of age is necessary. Objective To compare upper arm fat and muscle measurements in stunted and non-stunted children aged 0-24 months of age. Methods We analyzed secondary data of the Division of Nutrition and Metabolic Disease, Department of Child Health, Universitas Gadjah Mada Medical School, Yogyakarta which were collected using cluster random sampling from the Yogyakarta Special Province. We compared upper arm fat area (UFA, including the upper arm fat area estimate (UFE and the upper arm fat percentage (UFP, as well as upper arm muscle area (UMA and upper arm muscle area estimate (UME, among stunted and non-stunted children aged 0-24 months. Results We analyzed 2,195 children. The prevalence of stunting was 354/2,195 (16.1%. The UFA, UFE, and UFP among stunted children were significantly lower compared to non-stunted children aged 7-12 months [UFA: 4.48 vs. 5.05 cm2 (P <0.001, respectively; UFE: 4.88 vs. 5.55 cm2 (P <0.001, respectively; and UFP: 30.82 vs. 32.58% (P = 0.03, respectively]. The UMA in children aged 7-12 months was also significantly lower in stunted than in non-stunted children [11.31 vs. 11.79 cm2 (P = 0.02, respectively], as well as in children aged 13-24 months [11.05 vs. 11.75 cm2 (P <0.001, respectively]. In addition, the UME in children aged 13-24 months was significantly lower in stunted compared to non-stunted children [10.50 vs. 11.18 cm2 (P <0.001, respectively]. Conclusion The UFA in children aged 7-12 months is smaller in stunted than in non-stunted children, whereas UMA in children aged 7-12 months and 13-24 months was smaller in stunted compared to non-stunted children.

Asymmetric cell division of stem cells in the lung and other systems

2014-07-01

Full Text Available New insights have been added to identification, behavior and cellular properties of embryonic and tissue-specific stem cells over the last few years. The modes of stem cell division, asymmetric versus symmetric, are tightly regulated during development and regeneration. The proper choice of a stem cell to divide asymmetrically or symmetrically has great consequences for development and disease because inappropriate asymmetric division disrupts organ morphogenesis, whereas uncontrolled symmetric division induces tumorigenesis. Therefore, understanding the behavior of lung stem cells could identify innovative solutions for restoring normal morphogenesis and/or regeneration of different organs. In this concise review, we describe recent studies in our laboratory about the mode of division of lung epithelial stem cells. We also compare asymmetric cell division in the lung stem cells with other tissues in different organisms.

A crucial open problem inS large-scale quantum networks is how to efficiently transmit quantum data among many pairs of users via a common data-transmission medium. We propose a solution by developing a quantum code division multiple access (q-CDMA) approach in which quantum information is chaotically encoded to spread its spectral content, and then decoded via chaos synchronization to separate different sender-receiver pairs. In comparison to other existing approaches, such as frequency division multiple access (FDMA), the proposed q-CDMA can greatly increase the information rates per channel used, especially for very noisy quantum channels.

The morphological symmetry of the division process of Escherichia coli is well-known. Recent studies verified that, in optimal growth conditions, most divisions are symmetric, although there are exceptions. We investigate whether such morphological asymmetries in division introduce functional asymmetries between sister cells, and assess the robustness of the symmetry in division to mild chemical stresses and sub-optimal temperatures. First, we show that the difference in size between daughter cells at birth is positively correlated to the difference between the numbers of fluorescent protein complexes inherited from the parent cell. Next, we show that the degree of symmetry in division observed in optimal conditions is robust to mild acidic shift and to mild oxidative stress, but not to sub-optimal temperatures, in that the variance of the difference between the sizes of sister cells at birth is minimized at 37 °C. This increased variance affects the functionality of the cells in that, at sub-optimal temperatures, larger/smaller cells arising from asymmetric divisions exhibit faster/slower division times than the mean population division time, respectively. On the other hand, cells dividing faster do not do so at the cost of morphological symmetry in division. Finally we show that at suboptimal temperatures the mean distance between the nucleoids increases, explaining the increased variance in division. We conclude that the functionality of E. coli cells is not immune to morphological asymmetries at birth, and that the effectiveness of the mechanism responsible for ensuring the symmetry in division weakens at sub-optimal temperatures.

Although the tools of complexity research have been applied to the phenomenon of labor division, its underlying mechanisms are still unclear. Researchers have used evolutionary models to study labor division in terms of global optimization, but focusing on individual optimization is a more realistic, real-world approach. We do this by first developing a multi-agent model that takes into account information-sharing and learning-by-doing and by using simulations to demonstrate the emergence of labor division. We then use a master equation method and find that the computational results are consistent with the results of the simulation. Finally we find that the core underlying mechanisms that cause labor division are learning-by-doing, information cost, and random fluctuation.

Security analysis of orthogonal-frequency-division-multiplexing-based continuous-variable quantum key distribution with imperfect modulation

Science.gov (United States)

Zhang, Hang; Mao, Yu; Huang, Duan; Li, Jiawei; Zhang, Ling; Guo, Ying

2018-05-01

We introduce a reliable scheme for continuous-variable quantum key distribution (CV-QKD) by using orthogonal frequency division multiplexing (OFDM). As a spectrally efficient multiplexing technique, OFDM allows a large number of closely spaced orthogonal subcarrier signals used to carry data on several parallel data streams or channels. We place emphasis on modulator impairments which would inevitably arise in the OFDM system and analyze how these impairments affect the OFDM-based CV-QKD system. Moreover, we also evaluate the security in the asymptotic limit and the Pirandola-Laurenza-Ottaviani-Banchi upper bound. Results indicate that although the emergence of imperfect modulation would bring about a slight decrease in the secret key bit rate of each subcarrier, the multiplexing technique combined with CV-QKD results in a desirable improvement on the total secret key bit rate which can raise the numerical value about an order of magnitude.

Education evolution: a historical perspective of associate degree nursing.

2009-05-01

Exploring the inception and growth of associate degree nursing education informs our understanding of what led to such explosive growth so that most of the nursing workforce is currently educated at the associate degree level. The success of associate degree nursing programs led to many divisive years in nursing education of differentiation of practice debates that were hardly productive. Work world practices and patient needs are creating pressures on community colleges to join forces with universities to increase the percentage of baccalaureate-educated nurses. Associate degree nursing education continues to evolve to meet the demands of a higher educated nursing workforce.

Earth Sciences Division annual report 1990

International Nuclear Information System (INIS)

1991-06-01

This Annual Report presents summaries of selected representative research activities grouped according to the principal disciplines of the Earth Sciences Division: Reservoir Engineering and Hydrogeology, Geology and Geochemistry, and Geophysics and Geomechanics. Much of the Division's research deals with the physical and chemical properties and processes in the earth's crust, from the partially saturated, low-temperature near-surface environment to the high-temperature environments characteristic of regions where magmatic-hydrothermal processes are active. Strengths in laboratory and field instrumentation, numerical modeling, and in situ measurement allow study of the transport of mass and heat through geologic media -- studies that now include the appropriate chemical reactions and the hydraulic-mechanical complexities of fractured rock systems. Of particular note are three major Division efforts addressing problems in the discovery and recovery of petroleum, the application of isotope geochemistry to the study of geodynamic processes and earth history, and the development of borehole methods for high-resolution imaging of the subsurface using seismic and electromagnetic waves. In 1989 a major DOE-wide effort was launched in the areas of Environmental Restoration and Waste Management. Many of the methods previously developed for and applied to deeper regions of the earth will in the coming years be turned toward process definition and characterization of the very shallow subsurface, where man-induced contaminants now intrude and where remedial action is required

Normal and sonographic anatomy of selected peripheral nerves. Part II: Peripheral nerves of the upper limb

2012-06-01

Full Text Available The ultrasonographic examination is frequently used for imaging peripheral nerves. It serves to supplement the physical examination, electromyography, and magnetic resonance imaging. As in the case of other USG imaging studies, the examination of peripheral nerves is non-invasive, well-tolerated by patients, and relatively inexpensive. Part I of this article series described in detail the characteristic USG picture of peripheral nerves and the proper examination technique, following the example of the median nerve. This nerve is among the most often examined peripheral nerves of the upper limb. This part presents describes the normal anatomy and ultrasound picture of the remaining large nerve branches in the upper extremity and neck – the spinal accessory nerve, the brachial plexus, the suprascapular, axillary, musculocutaneous, radial and ulnar nerves. Their normal anatomy and ultrasonographic appearance have been described, including the division into individual branches. For each of them, specific reference points have been presented, to facilitate the location of the set trunk and its further monitoring. Sites for the application of the ultrasonographic probe at each reference point have been indicated. In the case of the ulnar nerve, the dynamic component of the examination was emphasized. The text is illustrated with images of probe positioning, diagrams of the normal course of the nerves as well as a series of ultrasonographic pictures of normal nerves of the upper limb. This article aims to serve as a guide in the ultrasound examination of the peripheral nerves of the upper extremity. It should be remembered that a thorough knowledge of the area’s topographic anatomy is required for this type of examination.

Interface control document between PUREX/UO3 Plant Transition and Solid Waste Disposal Division

Duncan, D.R.

1994-01-01

This interface control document (ICD) between PUREX/UO 3 Plant Transition (PPT) and Solid Waste Disposal Division (SWD) establishes at a top level the functional responsibilities of each division where interfaces exist between the two divisions. Since the PUREX Transition and Solid Waste Disposal divisions operate autonomously, it is important that each division has a clear understanding of the other division's expectations regarding these interfaces. This ICD primarily deals with solid wastes generated by the PPT. In addition to delineating functional responsibilities, the ICD includes a baseline description of those wastes that will require management as part of the interface between the divisions. The baseline description of wastes includes waste volumes and timing for use in planning the proper waste management capabilities: the primary purpose of this ICD is to ensure defensibility of expected waste stream volumes and Characteristics for future waste management facilities. Waste descriptions must be as complete as-possible to ensure adequate treatment, storage, and disposal capability will exist. The ICD also facilitates integration of existing or planned waste management capabilities of the PUREX. Transition and Solid Waste Disposal divisions. The ICD does not impact or affect the existing processes or procedures for shipping, packaging, or approval for shipping wastes by generators to the Solid Waste Division

those with minimum sizes, such as rock lumps. They reflect primarily the degradation of megablocks as a result of their destruction due to high stresses in excess of the tensile strength of the medium. This group may also include blocks which formation is related to convection in the upper mantle layer, asthenosphere. There are grounds to assume that through the vast intermediate interval of geologic time, including supercycles of Kenorlend, Rodin, and and partically Pangea, the formation of the large lithospheric blocks was controlled by convection, and later on, they were 'fragmented' under the physical laws of destruction of solid bodies. However, it is difficult to clearly distinguish between the processes that predetermine the hierarchy of formation of the block structures of various origins – sizes of ancient lithospheric blocks cannot be estimated unambiguously.Thus, mantle convection is a genetic endogenous source of initial divisibility of the cooling upper cover of the Earth and megablock divisibility of the lithosphere in the subsequent and recent geodynamic development stages. At the present stage, regular patterns of the lithospheric block divisibility of various scales are observed at all the hierarchic levels. The areas of the lithospheric megaplates result from regular changes of convective processes in the mantle, which influenced the formation of plates and plate kinematics. Fragmentation of the megaplates into smaller ones is a result of destruction of the solid lithosphere under the physical laws of destruction of solid bodies under the impact of high stresses.

Parenthood and Domestic Division of Labour in Spain, 2002-2010

2015-01-01

Full Text Available The literature on the division of domestic work has revealed the influence of the life cycle on family organization. Concretely, the arrival of children seems to have a signifi cant impact on the division of domestic tasks. This article looks at the effect of parenthood in the Spanish case, examining whether couples with children have a more traditional division of work than couples without children, and if so, in what way, and whether there have been changes in this trend over time. For this purpose, we follow the the empirical strategy of Dribe and Stanfors (2009 for the Swedish case, analyzing the time devoted to different activities using data from time use surveys from 2002-2003 and 2009-2010. The results show that couples with children have a more traditional division of labor than couples without children, and that it is also affected by the age of the children. In addition, our fi ndings show this trend was less pronounced in 2009-10.

Asymmetric cell division requires specific mechanisms for adjusting global transcription.

Most cells divide symmetrically into two approximately identical cells. There are many examples, however, of asymmetric cell division that can generate sibling cell size differences. Whereas physical asymmetric division mechanisms and cell fate consequences have been investigated, the specific problem caused by asymmetric division at the transcription level has not yet been addressed. In symmetrically dividing cells the nascent transcription rate increases in parallel to cell volume to compensate it by keeping the actual mRNA synthesis rate constant. This cannot apply to the yeast Saccharomyces cerevisiae, where this mechanism would provoke a never-ending increasing mRNA synthesis rate in smaller daughter cells. We show here that, contrarily to other eukaryotes with symmetric division, budding yeast keeps the nascent transcription rates of its RNA polymerases constant and increases mRNA stability. This control on RNA pol II-dependent transcription rate is obtained by controlling the cellular concentration of this enzyme. © The Author(s) 2017.

Under the mandate contained in the FY 1976 NASA Authorization Act, the National Aeronautics and Space Administration (NASA) has developed and is implementing a comprehensive program of research, technology development, and monitoring of the Earth's upper atmosphere, with emphasis on the upper troposphere and stratosphere. This program aims at expanding our chemical and physical understanding to permit both the quantitative analysis of current perturbations as well as the assessment of possible future changes in this important region of our environment. It is carried out jointly by the Upper Atmosphere Research Program (UARP) and the Atmospheric Chemistry Modeling and Analysis Program (ACMAP), both managed within the Research Division in the Office of Earth Science at NASA. Significant contributions to this effort have also been provided by the Atmospheric Effects of Aviation Project (AEAP) of NASA's Office of Aero-Space Technology. The long-term objectives of the present program are to perform research to: understand the physics, chemistry, and transport processes of the upper troposphere and the stratosphere and their control on the distribution of atmospheric chemical species such as ozone; assess possible perturbations to the composition of the atmosphere caused by human activities and natural phenomena (with a specific emphasis on trace gas geographical distributions, sources, and sinks and the role of trace gases in defining the chemical composition of the upper atmosphere); understand the processes affecting the distributions of radiatively active species in the atmosphere, and the importance of chemical-radiative-dynamical feedbacks on the meteorology and climatology of the stratosphere and troposphere; and understand ozone production, loss, and recovery in an atmosphere with increasing abundances of greenhouse gases. The current report is composed of two parts. Part 1 summarizes the objectives, status, and accomplishments of the research tasks supported
