Students' and teachers' misapplication of le chatelier's principle: Implications for the teaching of chemical equilibrium

Science.gov (United States)

Quílez-Pardo, Juan; Solaz-Portolés, Joan Josep

The aim of this article was to study the reasons, strategies, and procedures that both students and teachers use to solve some chemical equilibrium questions and problems. Inappropriate conceptions on teaching and a lack of knowledge regarding the limited usefulness of Le Chatelier's principle, with its vague and ambiguous formulation and textbook presentation, may be some of the sources of misconceptions about the prediction of the effect of changing conditions on chemical equilibrium. To diagnose misconceptions and their possible sources, a written test was developed and administered to 170 1st-year university chemistry students. A chemical equilibrium problem, relating to the students' test, was solved by 40 chemistry teachers. First, we ascertained that teacher's conceptions might influence the problem-solving strategies of the learner. Based on this first aspect, our discussion also concerns students' and teachers' misconceptions related to the Le Chatelier's principle. Misconceptions emerged through: (a) misapplication and misunderstanding of Le Chatelier's principle; (b) use of rote-learning recall and algorithmic procedures; (c) incorrect control of the variables involved; (d) limited use of the chemical equilibrium law; (e) a lack of mastery of chemical equilibrium principles and difficulty in transferring such principles to new situations. To avoid chemical equilibrium misconceptions, a specific pattern of conceptual and methodological change may be considered.Received: 16 November 1993; Revised: 21 September 1994;

The use of Information and Communication Technology (ICT) in mathematics instruction will help students in building conceptual understanding. One of the software products used in mathematics instruction is GeoGebra. The program enables simple visualization of complex geometric concepts and helps improve students' understanding of geometric concepts. Instruction applying brain-based learning principles is one oriented at the efforts of naturally empowering the brain potentials which enable students to build their own knowledge. One of the goals of mathematics instruction in school is to develop mathematical communication ability. Mathematical representation is regarded as a part of mathematical communication. It is a description, expression, symbolization, or modeling of mathematical ideas/concepts as an attempt of clarifying meanings or seeking for solutions to the problems encountered by students. The research aims to develop a learning model and teaching materials by applying the principles of brain-based learning aided by GeoGebra to improve junior high school students' mathematical representation ability. It adopted a quasi-experimental method with the non-randomized control group pretest-posttest design and the 2x3 factorial model. Based on analysis of the data, it is found that the increase in the mathematical representation ability of students who were treated with mathematics instruction applying the brain-based learning principles aided by GeoGebra was greater than the increase of the students given conventional instruction, both as a whole and based on the categories of students' initial mathematical ability.

Tam, Greta; Liu, Sida

2018-01-01

Background Web-based public health courses are becoming increasingly popular. “Public Health Principles in Disaster and Medical Humanitarian Response” is a unique Web-based course in Hong Kong. This course aimed to fill a public health training gap by reaching out to postgraduates who are unable to access face-to-face learning. Objective The aim of this paper was to use a structured framework to objectively evaluate the effectiveness of a Web-based course according to Greenhalgh et al’s quality framework and the Donabedian model to make recommendations for program improvement. Methods An interim evaluation of the first cohort of students in 2014 was conducted according to the Donabedian model and a quality framework by Greenhalgh et al using objective and self-reported data. Results Students who registered for the first cohort (n=1152) from June 16, 2014 to December 15, 2014 (6 months) were surveyed. Two tutors and the course director were interviewed. The Web-based course was effective in using technology to deliver suitable course materials and assessment and to enhance student communication, support, and learning. Of the total number of students registered, 59.00% (680/1152) were nonlocal, originating from 6 continents, and 72.50% (835/1152) possessed a bachelor’s or postgraduate degree. The completion rate was 20.00% (230/1152). The chi-square test comparing students who completed the course with dropouts showed no significant difference in gender (P=.40), age (P=.98), occupation (P=.43), or qualification (P=.17). The cost (HK $272 per student) was lower than that of conducting a face-to-face course (HK $4000 per student). Conclusions The Web-based course was effective in using technology to deliver a suitable course and reaching an intended audience. It had a higher completion rate than other Web-based courses. However, sustainable sources of funding may be needed to maintain the free Web-based course. PMID:29374007

The base rate principle and the fairness principle in social judgment.

Science.gov (United States)

Cao, Jack; Banaji, Mahzarin R

2016-07-05

Meet Jonathan and Elizabeth. One person is a doctor and the other is a nurse. Who is the doctor? When nothing else is known, the base rate principle favors Jonathan to be the doctor and the fairness principle favors both individuals equally. However, when individuating facts reveal who is actually the doctor, base rates and fairness become irrelevant, as the facts make the correct answer clear. In three experiments, explicit and implicit beliefs were measured before and after individuating facts were learned. These facts were either stereotypic (e.g., Jonathan is the doctor, Elizabeth is the nurse) or counterstereotypic (e.g., Elizabeth is the doctor, Jonathan is the nurse). Results showed that before individuating facts were learned, explicit beliefs followed the fairness principle, whereas implicit beliefs followed the base rate principle. After individuating facts were learned, explicit beliefs correctly aligned with stereotypic and counterstereotypic facts. Implicit beliefs, however, were immune to counterstereotypic facts and continued to follow the base rate principle. Having established the robustness and generality of these results, a fourth experiment verified that gender stereotypes played a causal role: when both individuals were male, explicit and implicit beliefs alike correctly converged with individuating facts. Taken together, these experiments demonstrate that explicit beliefs uphold fairness and incorporate obvious and relevant facts, but implicit beliefs uphold base rates and appear relatively impervious to counterstereotypic facts.

The Principle-Based Method of Practical Ethics.

Science.gov (United States)

Spielthenner, Georg

2017-09-01

This paper is about the methodology of doing practical ethics. There is a variety of methods employed in ethics. One of them is the principle-based approach, which has an established place in ethical reasoning. In everyday life, we often judge the rightness and wrongness of actions by their conformity to principles, and the appeal to principles plays a significant role in practical ethics, too. In this paper, I try to provide a better understanding of the nature of principle-based reasoning. To accomplish this, I show in the first section that these principles can be applied to cases in a meaningful and sufficiently precise way. The second section discusses the question how relevant applying principles is to the resolution of ethical issues. This depends on their nature. I argue that the principles under consideration in this paper should be interpreted as presumptive principles and I conclude that although they cannot be expected to bear the weight of definitely resolving ethical problems, these principles can nevertheless play a considerable role in ethical research.

2015-04-01

We surveyed European medical schools regarding teaching of prudent antibiotic prescribing in the undergraduate curriculum. We performed a cross-sectional survey in 13 European countries (Belgium, Croatia, Denmark, France, Germany, Italy, Netherlands, Norway, Serbia, Slovenia, Spain, Switzerland, United Kingdom) in 2013. Proportional sampling was used, resulting in the selection of two to four medical schools per country. A standardized questionnaire based on literature review and validated by a panel of experts was sent to lecturers in infectious diseases, medical microbiology and clinical pharmacology. In-depth interviews were conducted with four lecturers. Thirty-five of 37 medical schools were included in the study. Prudent antibiotic use principles were taught in all but one medical school, but only four of 13 countries had a national programme. Interactive teaching formats were used less frequently than passive formats. The teaching was mandatory for 53% of the courses and started before clinical training in 71%. We observed wide variations in exposure of students to important principles of prudent antibiotic use among countries and within the same country. Some major principles were poorly covered (e.g. reassessment and duration of antibiotic therapy, communication skills). Whereas 77% of the respondents fully agreed that the teaching of these principles should be prioritized, lack of time, mainly due to rigid curriculum policies, was the main reported barrier to implementation. Given the study design, these are probably optimistic results. Teaching of prudent antibiotic prescribing principles should be improved. National and European programmes for development of specific learning outcomes or competencies are urgently needed. Copyright © 2014 European Society of Clinical Microbiology and Infectious Diseases.

This study examined students' perceptions of interprofessional practice within a framework of servant leadership principles, applied in the care of rural older adults utilizing a service learning model. Mobile wellness services were provided through the Idaho State University Senior Health Mobile project in a collaborative team approach in the community-based setting. Students from varied health professional programs were placed in teams for the provision of wellness care, with communication among team members facilitated by a health professions faculty member serving as field coordinator. The Interdisciplinary Education Perception Scale (IEPS) was used to measure students' perceptions of interprofessional practice using a pretest post-test research design. Multivariate analysis was performed revealing a significant pretest to post-test effect on students' perceptions as measured by factors inherent in the IEPS and deemed essential to effective interprofessional practice. Univariate analysis revealed a significant change in students' perception of professional competence and autonomy, actual cooperation and resource sharing within and across professions, and an understanding of the value and contributions of other professionals from pretest to post-test.

Elucidating the hard/soft acid/base principle: A perspective based on half-reactions

International Nuclear Information System (INIS)

Ayers, Paul W.; Parr, Robert G.; Pearson, Ralph G.

2006-01-01

A comprehensive analysis is presented for the acid-base double-exchange reaction as well as the associated acid-displacement and base-displacement 'half-reactions' with the goal of elucidating the meaning of the hard/soft acid/base (HSAB) principle and the conditions for its validity. When electron-transfer effects are important and other effects are negligible, the HSAB principle is driven by the surpassing stability of the soft acid/soft base product. When electrostatic effects dominate the reactivity, the HSAB principle is driven by the surpassing stability of the hard acid/hard base product. Because electron-transfer effects favor soft/soft interactions, while electrostatic effects favor hard/hard interactions, acid-base exchange reactions may be used to determine whether a reagent's reactivity is dominated by electron-transfer or by electrostatic effects. Because electron-transfer and electrostatic considerations separately favor the HSAB principle whenever the electronic chemical potentials of the acids and bases involved in the reaction are similar, our analysis provides strong support for the HSAB principle. The electronic chemical potential measures the intrinsic strength of acids and bases

I find that students have difficulty with Hamilton's principle, at least the first time they come into contact with it, and therefore it is worth designing some examples to help students grasp its complex meaning. This paper supplies the simplest example to consolidate the learning of the quoted principle: that of a free particle moving along a line. Next, students are challenged to add gravity to reinforce the argument and, finally, a two-dimensional motion in a vertical plane is considered. Furthermore these examples force us to be very clear about such an abstract principle

The effectiveness of signaling principle in virtual reality courseware towards achievement of transfer learning among students with different spatial ability

Past research revealed that students and society, in general, are relatively under-skilled in performing the practice of Islamic funeral management which is one of the "ibadah fardu kifayah" (a legal obligation that must be discharged by the Muslim community as a whole) in Islam. Participation among youth in managing funerals is relatively low, partly due to the ineffectiveness of the instructional approach. This paper aims to examine the effectiveness of the signaling principle in virtual reality courseware pertaining to the topic of Islamic Funeral Management in the Islamic Education subject to ensure the accomplishment of transfer learning among students with different spatial abilities. The study comprises of two phases namely the courseware development phase and treatment phase. The courseware development employs the Instructional Design Model by Alessi and Trollip. Besides that, the courseware is integrated with components of CLE, principles in Theory of CATLM and signaling principle in multimedia learning. The sample consisted of 130 Form Two students who were selected randomly from four Malaysian secondary schools. They were divided into two experimental groups with 63 students in group one and 67 students in group two. The experimental group one used VR courseware without the signaling principle (VRTI) while experimental group two used the VR courseware with the signaling principle (VRDI). The experiment lasted for three weeks. ANOVA was utilised to analyse the data from this research. The findings showed significant differences between students who used VRDI in the transfer of learning compared to students who used VRTI.

2016-01-01

Full Text Available The aim of the publication is to demonstrate the implementation of general methodological principles of optional elementary school online foreign languages learning on an example of a virtual course for students of the second and third grades.Methods. The methods involve pedagogical modeling and projecting; the experience of foreign and Russian methodists, teachers and researchers is analysed, generalized and adjusted to the modern realias.Results and scientific novelty. On the basis of the requirements of the state educational standard and interest of pupils in computer games, the author’s technique of the combined facultative educational activities integrated to training in English at elementary school is developed. Online training in the form of games (additional to the major classroom activities gives a possibility of the choice of tasks interesting to children, studying the material at optimum comfortable and individual speed; it is possible to perform the tasks at home excluding the stressful situations that are specific to school examination, and allows pupils to master most effectively personal, metasubject and object competences. In general context of quality improvement of the general education, the modernization of educational process assumes not only justification of its new maintenance, but also restructuring of scientific and methodical support which has to meet essential needs of teachers and pupils, to facilitate access to necessary specific information. The lack of methodical base of creation of electronic distance resources for foreign-language education of younger school students has motivated the author to create own methodical concept of online training taking into account age of pupils. The complex of the general methodical principles is thoroughly considered; based on the general methodical principles, the proposed modular technique of the organization of an online class is created and implemented.

2013-12-16

To assist administrators and faculty members in colleges and schools of pharmacy by gathering expert opinion to frame, direct, and support investments in student leadership development. Twenty-six leadership instructors participated in a 3-round, online, modified Delphi process to define doctor of pharmacy (PharmD) student leadership instruction. Round 1 asked open-ended questions about leadership knowledge, skills, and attitudes to begin the generation of student leadership development guiding principles and competencies. Statements were identified as guiding principles when they were perceived as foundational to the instructional approach. Round 2 grouped responses for agreement rating and comment. Group consensus with a statement as a guiding principle was set prospectively at 80%. Round 3 allowed rating and comment on guidelines, modified from feedback in round 2, that did not meet consensus. The principles were verified by identifying common contemporary leadership development approaches in the literature. Twelve guiding principles, related to concepts of leadership and educational philosophy, were defined and could be linked to contemporary leadership development thought. These guiding principles describe the motivation for teaching leadership, the fundamental precepts of student leadership development, and the core tenets for leadership instruction. Expert opinion gathered using a Delphi process resulted in guiding principles that help to address many of the fundamental questions that arise when implementing or refining leadership curricula. The principles identified are supported by common contemporary leadership development thought.

Ethnographic research with adolescent students: situated fieldwork ethics and ethical principles governing human research.

Science.gov (United States)

Hemmings, Annette

2009-12-01

This paper explores ethical dilemmas in situated fieldwork ethics concerning ethnographic studies of adolescent students. While consequentialist and deontological ethics form the basis of the ethical stances shared by ethnographers and research ethics committees, the interpretation of those principles may diverge in school-based ethnography with adolescent students because of the particular role of the adult ethnographer vis-à-vis developmentally immature adolescents not held legally responsible for many of their actions. School ethnographers attempt to build trust with adolescent participants in order to learn about their hidden cultural worlds, which may involve activities that are very harmful to the youths involved. They face many difficult and sometimes unexpected choices, including whether to intervene and how to represent events and adolescents in published findings. Scenarios with examples drawn from research conducted in public high schools are used to illustrate and explicate dilemmas in formal research and latent insider/outsider roles and relations involving harmful adolescent behaviors, advocacy, and psychological trauma. Also examined are analytical procedures used to construct interpretations leading to representations of research participants in the resulting publication.

Time-advance algorithms based on Hamilton's principle

International Nuclear Information System (INIS)

Lewis, H.R.; Kostelec, P.J.

1993-01-01

Time-advance algorithms based on Hamilton's variational principle are being developed for application to problems in plasma physics and other areas. Hamilton's principle was applied previously to derive a system of ordinary differential equations in time whose solution provides an approximation to the evolution of a plasma described by the Vlasov-Maxwell equations. However, the variational principle was not used to obtain an algorithm for solving the ordinary differential equations numerically. The present research addresses the numerical solution of systems of ordinary differential equations via Hamilton's principle. The basic idea is first to choose a class of functions for approximating the solution of the ordinary differential equations over a specific time interval. Then the parameters in the approximating function are determined by applying Hamilton's principle exactly within the class of approximating functions. For example, if an approximate solution is desired between time t and time t + Δ t, the class of approximating functions could be polynomials in time up to some degree. The issue of how to choose time-advance algorithms is very important for achieving efficient, physically meaningful computer simulations. The objective is to reliably simulate those characteristics of an evolving system that are scientifically most relevant. Preliminary numerical results are presented, including comparisons with other computational methods

This study examines the perceived impact of a novel clinical teaching method based on FAIR principles (feedback, activity, individuality and relevance) on students' learning on clinical placement. This was a qualitative research study. Participants were third year and final year medical students attached to one UK vascular firm over a four-year period (N=108). Students were asked to write a reflective essay on how FAIRness approach differs from previous clinical placement, and its advantages and disadvantages. Essays were thematically analysed and globally rated (positive, negative or neutral) by two independent researchers. Over 90% of essays reported positive experiences of feedback, activity, individuality and relevance model. The model provided multifaceted feedback; active participation; longitudinal improvement; relevance to stage of learning and future goals; structured teaching; professional development; safe learning environment; consultant involvement in teaching. Students perceived preparation for tutorials to be time intensive for tutors/students; a lack of teaching on medical sciences and direct observation of performance; more than once weekly sessions would be beneficial; some issues with peer and public feedback, relevance to upcoming exam and large group sizes. Students described negative experiences of "standard" clinical teaching. Progressive teaching programmes based on the FAIRness principles, feedback, activity, individuality and relevance, could be used as a model to improve current undergraduate clinical teaching.

2015-06-01

This paper starts with discussing the principle based on which the celebrated orthogonal frequency division multiplexing (OFDM) signals are constructed. It then extends the same principle to construct the newly introduced generalized frequency division multiplexing (GFDM) signals. This novel derivation sheds light on some interesting properties of GFDM. In particular, our derivation seamlessly leads to an implementation of GFDM transmitter which has significantly lower complexity than what has been reported so far. Our derivation also facilitates a trivial understanding of how GFDM (similar to OFDM) can be applied in MIMO channels.

In 1968, Wilson and Jungner published 10 principles of screening that often represent the de facto starting point for screening decisions today; 50 years on, are these principles still the right ones? Our objectives were to review published work that presents principles for population-based screening decisions since Wilson and Jungner's seminal publication, and to conduct a Delphi consensus process to assess the review results. We conducted a systematic review and modified Delphi consensus process. We searched multiple databases for articles published in English in 1968 or later that were intended to guide population-based screening decisions, described development and modification of principles, and presented principles as a set or list. Identified sets were compared for basic characteristics (e.g., number, categorization), a citation analysis was conducted, and principles were iteratively synthesized and consolidated into categories to assess evolution. Participants in the consensus process assessed the level of agreement with the importance and interpretability of the consolidated screening principles. We identified 41 sets and 367 unique principles. Each unique principle was coded to 12 consolidated decision principles that were further categorized as disease/condition, test/intervention or program/system principles. Program or system issues were the focus of 3 of Wilson and Jungner's 10 principles, but comprised almost half of all unique principles identified in the review. The 12 consolidated principles were assessed through 2 rounds of the consensus process, leading to specific refinements to improve their relevance and interpretability. No gaps or missing principles were identified. Wilson and Jungner's principles are remarkably enduring, but increasingly reflect a truncated version of contemporary thinking on screening that does not fully capture subsequent focus on program or system principles. Ultimately, this review and consensus process provides a

2015-03-25

To develop, implement, and evaluate a course-based, cross-cultural student interaction using real-time videoconferencing between universities in Canada and Qatar. A professional skills simulation practice session on smoking cessation was run for students in Qatar (n=22) and Canada (n=22). Students role played cases in small group situations and then interacted with colleagues from the other country regarding culturally challenging situations and communication strategies. Students were assessed on analytical content and communication skills through faculty member and peer evaluation. Cultural competency outcomes were assessed using a postsession survey. Overall, 92.3% of respondents agreed that learning was enhanced through the cross-cultural exchange, and 94.9% agreed that insight was gained into the health-related issues and needs of people from another culture. A course-based, cross-cultural interaction was an effective method to incorporate cultural competency principles into student learning. Future initiatives should increase direct student interaction and focus on culturally sensitive topics.

Changing from a Rules-based to a Principles-based Accounting Logic: A Review

Directory of Open Access Journals (Sweden)

Marta Silva Guerreiro

2014-06-01

Full Text Available We explore influences on unlisted companies when Portugal moved from a code law, rules-based accounting system, to a principles-based accounting system of adapted International Financial Reporting Standards (IFRS. Institutionalisation of the new principles-based system was generally facilitated by a socio-economic and political context that increasingly supported IFRS logic. This helped central actors gain political opportunity, mobilise important allies, and accommodate major protagonists. The preparedness of unlisted companies to adopt the new IFRS-based accounting system voluntarily was explained by their desire to maintain social legitimacy. However, it was affected negatively by the embeddedness of rule-based practices in the ‘old’ prevailing institutional logic.

Do medical students with A-level mathematics have a better understanding of the principles behind evidence-based medicine?

Science.gov (United States)

Ben-Shlomo, Y; Fallon, U; Sterne, J; Brookes, S

2004-12-01

With the advent of evidence-based medicine, medical students, doctors and other healthcare professionals are required to be more skilled in the interpretation and manipulation of numerical data. The authors observed that undergraduate students without A-level mathematics expressed concern as to their ability to cope with an epidemiology and biostatistics course. It was hypothesized that these anxieties reflected differences in attitudes to numerical manipulation rather than any real lack of competence. Mean exam performance scores were compared for 498 first-year medical students between 2000 and 2002 depending on whether the students did or did not have A-level mathematics. The data revealed no difference in performance. Students without mathematics A-level scored marginally worse (-1.1%, 95% CI -3.1% to 0.8%, p=0.20) but were no more likely to fail the exam (odds ratio=0.98, 95% CI 0.40 to 2.6, p=0.9). It is concluded that some students experience 'numerophobia'-- a perceived and, it is thought, disproportionate fear of numbers and simple mathematical manipulation. This may act as a psychological barrier for future evidence-based practitioners.

The importance and value of the principles of evidence-based practice (EBP) in the decision-making process is recognized by speech-language therapists (SLTs) worldwide and as a result curricula for speech-language therapy students incorporated EBP principles. However, the willingness actually to use EBP principles in their future profession not only depends on EBP knowledge and skills, but also on self-efficacy and task value students perceive towards EBP. To investigate the relation between EBP knowledge and skills, and EBP self-efficacy and task value in different year groups of Dutch SLT students. Students from three year groups filled in a tool that measured EBP knowledge and skills: the Dutch Modified Fresno (DMF). EBP self-efficacy and task value were assessed by using a 20-item questionnaire. Both tools were validated for this population. Mean scores for the three year groups were calculated and tested for group differences using a one-way analysis of variance (ANOVA) with a post-hoc Games-Howell procedure. With a multiple linear regression technique it was assessed whether EBP self-efficacy and task value predict learning achievement scores on the DMF. Other possible predictors included in the model were: level of prior education, standard of English, having had mathematics in prior education and the SLT study year. A total of 149 students filled in both measurement tools. Mean scores on EBP knowledge and skills were significantly different for the three year groups, with students who were further along their studies scoring higher on the DMF. Mean scores on the EBP self-efficacy and task value questionnaire were the same for the three year groups: all students valued EBP positive but self-efficacy was low in all groups. Of the possible predictors, only the year in which students study and EBP self-efficacy were significant predictors for learning achievements in EBP. Despite a significant increase in EBP knowledge and skills over the years as assessed by

Full Text Available Medical students must understand the principles of ultrasonography (US, because US examinations are an important component of patient care in clinical practice. Pocket-sized ultrasound devices have the benefits of accessibility and ease of use. The primary objective of the present study was to evaluate the educational value of these devices in terms of improving medical student interest and understanding of US and sonographic anatomy.We added a US training program comprised of a self-study learning module and a hands-on training session to a two-week block curriculum of medical imaging for first year medical students (n = 40. Multiple pocket-sized US devices were used on a small-group basis during a single afternoon. Students were asked to complete a questionnaire before and after the US training session; these two questionnaires contained 6 and 10 questions, respectively, which were rated by students using a five-point Likert scale. In addition, understanding of sonographic anatomy was tested before and after the training program.Forty students completed the two questionnaires and the anatomy-related tests. Students found the program educationally valuable (4.37 ± 0.54 of 5 and reported that US practice was useful for improving their understanding of the principles of US examinations (4.23 ± 0.66 of 5 and sonographic anatomy (4.40 ± 0.55 of 5. Overall confidence at performing US examinations and understanding of sonographic anatomy were significantly increased after US training (increased overall confidence score, 1.87 ± 0.91 and improvement in sonographic anatomy score, 6.55 ± 1.55, p values < 0.001.US training using pocket-sized ultrasound devices was found to be educationally valuable for medical students in terms of improving understanding of US principles and familiarizing students with sonographic anatomy.

F. Anufrieva, the principle of objectivity. The study involved 30 future psychologists. After performing the exercises in the course "Psychodiagnostics" the students solved the task, which simulates diagnostic work of the psychologist with decriminalised teenager with deviant behavior. Students were asked to solve a problem in professional discourse – to put forward hypotheses about the causes of deviant behavior in everyday life is to point out the culprits of the situation. Additionally, students assessed their similarity with the hero of the diagnostic event. The results show that students who have managed to build up diagnostic skills to identify psychological causes of deviant behavior, both professionally and in everyday discourse grappled with the task model, regardless of the number of subjective similarities with her character. Students who have not sufficiently developed diagnostic skills, to avoid bias failed.

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.

New Student-Centered and Data-Based Approaches to Hydrology Education

Science.gov (United States)

Bloeschl, G.; Troch, P. A. A.; Sivapalan, M.

2014-12-01

Hydrology as a science has evolved over the last century. The knowledge base has significantly expanded, and there are requirements to meet with the new expectations of a science where the connections between the parts are just as important as the parts themselves. In this new environment, what should we teach, and how should we teach it? Given the limited time we have in an undergraduate (and even graduate) curriculum, what should we include, and what should we leave out? What new material and new methods are essential, as compared to textbooks? Past practices have assumed certain basics as being essential to undergraduate teaching. Depending on the professor's background, these include basic process descriptions (infiltration, runoff generation, evaporation etc.) and basic techniques (unit hydrographs, flood frequency analysis, pumping tests). These are taught using idealized (textbook) examples and examined to test this basic competence. The main idea behind this "reductionist" approach to teaching is that the students will do the rest of the learning during practice and apprenticeship in their workplaces. Much of current hydrology teaching follows this paradigm, and the books provide the backdrop to this approach. Our view is that this approach is less than optimum, as it does not prepare the students to face up to the new challenges of the changing world. It is our view that the basics of hydrologic science are not just a collection of individual processes and techniques, but process interactions and underlying concepts or principles, and a collection of techniques that highlights these, combined with student-driven and data-based learning that enables the students to see the manifestations of these process interactions and principles in action in real world situations. While the actual number of items that can be taught in the classroom by this approach in a limited period of time may be lower than in the traditional approach, it will help the students make

Shariah stock investing has become a widely discussed topic in financial industry as part of today's investment strategy. The strategy primarily applies market capitalization allocations. However, some researchers have argued that market capitalization weighting is inherently flawed and have advocated replacing market capitalization allocations with factor allocations. In this paper, we discuss the rationale for factor investing based on Musharakah principle. The essential elements or factors of Musharakah principle such as business sector, management capability, profitability growth and capital efficiency are embedded in the Shariah-compliant stock. We then transform these factors into indexation for better analysis and performance measurement. Investment universe for this research covers Malaysian stocks for the period of January 2009 to December 2013. We found out that these factor indexes have historically earned excess returns over market capitalization weighted indexes and experienced higher Sharpe Ratios.

Principle-Based Ethics and the Clean Development Mechanism

Bay, Ingrid; Oughton, Deborah

2003-01-01

Search for common values can go a long way resolving international political and social differences, and represents an area where ethical evaluation can offer an input to international legislation. This paper argues that a principle-based, normative approach should be applied to evaluation of Clean Development Mechanism (CDM) projects and the goal of sustainable development (SD). Primafacie ethical principles to promote weil-being, dignity and justice can be defined and supported from international agreements on sustainable developments. To promote coherency, these principles should then be specifled according to particular CDM-projects, to produce a set of norms that covers: 1) the different dimension to sustainable development, 2) the distribution of costs and benefits across time and place, and 3) consequences for different affected parties, including future generations and the environment

Lukin, Kara

2013-03-01

High school students in the United States are apathetic about science, technology, engineering and mathematics (STEM), and the workforce pipeline in these areas is collapsing. The lack of understanding of basic principles of biology means that students are unable to make educated decisions concerning their personal health. To address these issues, we have developed a simple, inquiry-based outreach lesson centered on a mouse dissection. Students learn key concepts in immunology and enhance their understanding of human organ systems. The experiment highlights aspects of the scientific method and authentic data collection and analysis. This hands-on activity stimulates interest in biology, personal health and careers in STEM fields. Here, we present all the information necessary to execute the lesson effectively with middle and high school students.

Chemical libraries contain thousands of compounds that need screening, which increases the need for computational methods that can rank or prioritize compounds. The tools of virtual screening are widely exploited to enhance the cost effectiveness of lead drug discovery programs by ranking chemical compounds databases in decreasing probability of biological activity based upon probability ranking principle (PRP). In this paper, we developed a novel ranking approach for molecular compounds inspired by quantum mechanics, called quantum probability ranking principle (QPRP). The QPRP ranking criteria would make an attempt to draw an analogy between the physical experiment and molecular structure ranking process for 2D fingerprints in ligand based virtual screening (LBVS). The development of QPRP criteria in LBVS has employed the concepts of quantum at three different levels, firstly at representation level, this model makes an effort to develop a new framework of molecular representation by connecting the molecular compounds with mathematical quantum space. Secondly, estimate the similarity between chemical libraries and references based on quantum-based similarity searching method. Finally, rank the molecules using QPRP approach. Simulated virtual screening experiments with MDL drug data report (MDDR) data sets showed that QPRP outperformed the classical ranking principle (PRP) for molecular chemical compounds.

Ocean and coastal practitioners work within existing financial constraints, jurisdictions, and legislative authorities to manage coastal and marine resources while seeking to promote and maintain a healthy and productive coastal economy. Fulfilling this mandate necessitates incorporation of best available science, including ecosystem-based management (EBM) into coastal and ocean management decisions. To do this, many agencies seek ways to apply lessons from ecological theory into their decision processes. However, making direct connections between science and management can be challenging, in part because there is no process for linking ecological principles (e.g., maintaining species diversity, habitat diversity, connectivity and populations of key species) with available data. Here we explore how incorporating emerging data and methods into resource management at a local scale can improve the overall health of our coastal and marine ecosystems. We introduce a new web-based interface, EcoPrinciples Connect, that links marine managers to scientific and geospatial information through the lens of these ecological principles, ultimately helping managers become more efficient, more consistent, and advance the integration of EBM. The EcoPrinciples Connect tool grew directly out of needs identified in response to a Center for Ocean Solutions reference guide, Incorporating Ecological Principles into California Ocean and Coastal Management: Examples from Practice. Here we illustrate how we have worked to translate the information in this guide into a co-developed, user-centric tool for agency staff. Specifically, we present a pilot project where we match publicly available data to the ecological principles for the California San Francisco Bay Conservation and Development Commission. We will share early lessons learned from pilot development and highlight opportunities for future transferability to an expanded group of practitioners.

The networked student: A design-based research case study of student constructed personal learning environments in a middle school science course

Science.gov (United States)

Drexler, Wendy

This design-based research case study applied a networked learning approach to a seventh grade science class at a public school in the southeastern United States. Students adapted emerging Web applications to construct personal learning environments for in-depth scientific inquiry of poisonous and venomous life forms. The personal learning environments constructed used Application Programming Interface (API) widgets to access, organize, and synthesize content from a number of educational Internet resources and social network connections. This study examined the nature of personal learning environments; the processes students go through during construction, and patterns that emerged. The project was documented from both an instructional and student-design perspective. Findings revealed that students applied the processes of: practicing digital responsibility; practicing digital literacy; organizing content; collaborating and socializing; and synthesizing and creating. These processes informed a model of the networked student that will serve as a framework for future instructional designs. A networked learning approach that incorporates these processes into future designs has implications for student learning, teacher roles, professional development, administrative policies, and delivery. This work is significant in that it shifts the focus from technology innovations based on tools to student empowerment based on the processes required to support learning. It affirms the need for greater attention to digital literacy and responsibility in K12 schools as well as consideration for those skills students will need to achieve success in the 21st century. The design-based research case study provides a set of design principles for teachers to follow when facilitating student construction of personal learning environments.

Dennis Coates

2001-04-01

Full Text Available Despite increasing use, little is known about the effectiveness of web-based instructional material. This study assesses the effectiveness of supplementary web-based materials and activities in introductory economics courses. We have collected data on 66 students from three principles sections that describe demographic characteristics, use of web-based instructional resources, and performance on graded quizzes and examinations. We use this data to statistically assess the effectiveness of the web-based material. Student utilization of web-based material was extensive. Students frequently used on-line practice quizzes and accessed the web-based material often. A sizable fraction of the students actively posted and read threaded discussions on the course bulletin board. The statistical analysis shows that both on-line computer graded practice quizzes and posting to the class bulletin board are positively correlated with student performance on the quizzes and exams, but use of web-based content and passive reading of bulletin board posts ("lurking" is not. These results suggest that faculty should focus more on developing self-test quizzes and effective bulletin board discussion projects and less on generating on-line content.

Can active learning principles be applied to the bioscience assessments of nursing students? A review of the literature.

Science.gov (United States)

Bakon, Shannon; Craft, Judy; Christensen, Martin; Wirihana, Lisa

2016-02-01

To explore if active learning principles be applied to nursing bioscience assessments and will this influence student perception of confidence in applying theory to practice? A review of the literature utilising searches of various databases including CINAHL, PUBMED, Google Scholar and Mosby's Journal Index. The literature search identified research from twenty-six original articles, two electronic books, one published book and one conference proceedings paper. Bioscience has been identified as an area that nurses struggle to learn in tertiary institutions and then apply to clinical practice. A number of problems have been identified and explored that may contribute to this poor understanding and retention. University academics need to be knowledgeable of innovative teaching and assessing modalities that focus on enhancing student learning and address the integration issues associated with the theory practice gap. Increased bioscience education is associated with improved patient outcomes therefore by addressing this "bioscience problem" and improving the integration of bioscience in clinical practice there will subsequently be an improvement in health care outcomes. From the literature several themes were identified. First there are many problems with teaching nursing students bioscience education. These include class sizes, motivation, concentration, delivery mode, lecturer perspectives, student's previous knowledge, anxiety, and a lack of confidence. Among these influences the type of assessment employed by the educator has not been explored or identified as a contributor to student learning specifically in nursing bioscience instruction. Second that educating could be achieved more effectively if active learning principles were applied and the needs and expectations of the student were met. Lastly, assessment influences student retention and the student experience and as such assessment should be congruent with the subject content, align with the learning

King, L; Gill, T; Allender, S; Swinburn, B

2011-05-01

Best practice in obesity prevention has generally been defined in terms of 'what' needs to be done while neglecting 'how'. A multifaceted definition of best practice, which combines available evidence on what actions to take, with an established process for interpreting this information in a specific community context, provides a more appropriate basis for defining the principles of best practice in community-based obesity prevention. Based on analysis of a range of literature, a preliminary set of principles was drafted and progressively revised through further analyses of published literature and a series of consultations. The framework for best practice principles comprises: community engagement, programme design and planning, evaluation, implementation and sustainability, and governance. Specific principles were formulated within this framework. While many principles were generic, distinctive features of obesity prevention were also covered. The engagement of end-users influenced the design of the formatting of the outputs, which represent three levels of knowledge transfer: detailed evidence summaries, guiding questions for programme planners and a briefer set of questions for simpler communication purposes. The best practice principles provide a valuable mechanism for the translation of existing evidence and experience into the decision-making processes for planning, implementing and evaluating the complex community-based interventions needed for successful obesity prevention. © 2010 The Authors. obesity reviews © 2010 International Association for the Study of Obesity.

Principles of Fourier analysis

CERN Document Server

Howell, Kenneth B

2001-01-01

Fourier analysis is one of the most useful and widely employed sets of tools for the engineer, the scientist, and the applied mathematician. As such, students and practitioners in these disciplines need a practical and mathematically solid introduction to its principles. They need straightforward verifications of its results and formulas, and they need clear indications of the limitations of those results and formulas.Principles of Fourier Analysis furnishes all this and more. It provides a comprehensive overview of the mathematical theory of Fourier analysis, including the development of Fourier series, "classical" Fourier transforms, generalized Fourier transforms and analysis, and the discrete theory. Much of the author''s development is strikingly different from typical presentations. His approach to defining the classical Fourier transform results in a much cleaner, more coherent theory that leads naturally to a starting point for the generalized theory. He also introduces a new generalized theory based ...

Koivisto, J-M; Haavisto, E; Niemi, H; Haho, P; Nylund, S; Multisilta, J

2018-01-01

Nurses sometimes lack the competence needed for recognising deterioration in patient conditions and this is often due to poor clinical reasoning. There is a need to develop new possibilities for learning this crucial competence area. In addition, educators need to be future oriented; they need to be able to design and adopt new pedagogical innovations. The purpose of the study is to describe the development process and to generate principles for the design of nursing simulation games. A design-based research methodology is applied in this study. Iterative cycles of analysis, design, development, testing and refinement were conducted via collaboration among researchers, educators, students, and game designers. The study facilitated the generation of reusable design principles for simulation games to guide future designers when designing and developing simulation games for learning clinical reasoning. This study makes a major contribution to research on simulation game development in the field of nursing education. The results of this study provide important insights into the significance of involving nurse educators in the design and development process of educational simulation games for the purpose of nursing education.

2016-01-01

The application of ethical principles within the teaching profession and nursing practice forms the core of the nurse educator's professional ethics. However, research focusing on the professional ethics of nurse educators is scarce. To describe ethical principles and issues relating to the work of nurse educators from the perspectives of both nurse educators themselves and nursing students. A descriptive study using cross-sectional data and content analysis. Nursing education program involving students from nine polytechnics in Finland. Nursing students (n=202) and nurse educators (n=342). Data were derived from an online survey, with two open-ended questions: Nursing students and nurse educators were asked to name the three main ethical principles that guide the work of nurse educators and also to describe ethical issues involved in the work. Students most often named professionalism, justice, and equality as the main ethical principles for a nurse educator. Nurse educators considered justice, equality, and honesty as the main ethical principles. The content analysis showed that professionalism and the relationship between educator and student were the key categories for ethical issues as perceived by nursing students. Nursing students most often identified inequality between the nurse educator and nursing student as the ethical issue faced by the nurse educator. Nursing students and nurse educators differed somewhat both in their views of the ethical principles guiding an educator's work and in the ethical issues arising in the work.

Full Text Available Shift report is an essential method for nursing staff to carry out health care communication. The most important purpose of the shift report is to ensure the safety of patients and to provide continuous care. Nursing students are inadequate of clinical experience and rational organization during patient care. They may not be able to handle the critically ill patients and pass the messages to the following nursing staff. ISBAR (Identify, Situation, Background, Assessment and Recommendation tool is increasingly being utilized as a format for structured shift report communication. In this study, a scale of ISBAR principles is designed to provide students with self-assessment and teachers with evaluation, in a way to improve nursing students’ self-awareness of shift report. Hopefully, with the use of the scale of ISBAR, nursing students are able to complete shift report in systemic integrity and orderliness during clinical placement.

2018-03-01

It is crucial that nursing students develop skills and confidence in using Evidence-Based Practice principles early in their education. This should be assessed with valid tools however, to date, few measures have been developed and applied to the student population. To examine the structural validity of the Student Evidence-Based Practice Questionnaire (S-EBPQ), with an Australian online nursing student cohort. A cross-sectional study for constructing validity. Three hundred and forty-five undergraduate nursing students from an Australian regional university were recruited across two semesters. Confirmatory Factor Analysis was used to examine the structural validity. Confirmatory Factor Analysis was applied which resulted in a good fitting model, based on a revised 20-item tool. The S-EBPQ tool remains a psychometrically robust measure of evidence-based practice use, attitudes, and knowledge and skills and can be applied in an online Australian student context. The findings of this study provided further evidence of the reliability and four factor structure of the S-EBPQ. Opportunities for further refinement of the tool may result in improvements in structural validity. Copyright © 2018 Elsevier Ltd. All rights reserved.

2011-08-01

The Association of American Medical Colleges' Institute for Improving Medical Education's report entitled 'Effective Use of Educational Technology' called on researchers to study the effectiveness of multimedia design principles. These principles were empirically shown to result in superior learning when used with college students in laboratory studies, but have not been studied with undergraduate medical students as participants. A pre-test/post-test control group design was used, in which the traditional-learning group received a lecture on shock using traditionally designed slides and the modified-design group received the same lecture using slides modified in accord with Mayer's principles of multimedia design. Participants included Year 3 medical students at a private, midwestern medical school progressing through their surgery clerkship during the academic year 2009-2010. The medical school divides students into four groups; each group attends the surgery clerkship during one of the four quarters of the academic year. Students in the second and third quarters served as the modified-design group (n=91) and students in the fourth-quarter clerkship served as the traditional-design group (n=39). Both student cohorts had similar levels of pre-lecture knowledge. Both groups showed significant improvements in retention (paffect transfer of learning. Further research on applying the principles of multimedia design to medical education is needed to verify the impact it has on the long-term learning of medical students, as well as its impact on other forms of multimedia instructional programmes used in the education of medical students. © Blackwell Publishing Ltd 2011.

Assessing participants' perceptions on group-based principles for action in community-based health enhancing physical activity programmes: The APEF tool.

Science.gov (United States)

Herens, Marion; Wagemakers, Annemarie

2017-12-01

In community-based health enhancing physical activity (CBHEPA) programmes, group-based principles for action such as active participation, enjoyment, and fostering group processes are widely advocated. However, not much is known about participants' perceptions of these principles as there are no assessment tools available. Therefore, this article describes the development of the APEF (Active Participation, Enjoyment, and Fostering group processes) tool and reports on its implementation in a Dutch CBHEPA programme. Indicators for the principles have been identified from literature research, interviews with professionals, and secondary analysis of three group interviews with 11 practitioners. To address the identified indicators, the APEF tool was developed, pretested, and used in 10 focus groups with 76 participants. The APEF tool consists of eight statements about group-based principles for action, on which CBHEPA participants vote, followed by in-depth discussion. The voting procedure engages participants. Spider diagrams visualise participants' perceptions of group-based principles. The APEF tool addresses the challenge of relating group level outcomes to individual outcomes such as physical activity behaviour. The tool facilitates as well as evaluates group-based principles for action, it stimulates dialogue and is culturally sensitive, but it needs strong facilitating skills to manage group dynamics.

Computer-based teaching module design: principles derived from learning theories.

Science.gov (United States)

Lau, K H Vincent

2014-03-01

The computer-based teaching module (CBTM), which has recently gained prominence in medical education, is a teaching format in which a multimedia program serves as a single source for knowledge acquisition rather than playing an adjunctive role as it does in computer-assisted learning (CAL). Despite empirical validation in the past decade, there is limited research into the optimisation of CBTM design. This review aims to summarise research in classic and modern multimedia-specific learning theories applied to computer learning, and to collapse the findings into a set of design principles to guide the development of CBTMs. Scopus was searched for: (i) studies of classic cognitivism, constructivism and behaviourism theories (search terms: 'cognitive theory' OR 'constructivism theory' OR 'behaviourism theory' AND 'e-learning' OR 'web-based learning') and their sub-theories applied to computer learning, and (ii) recent studies of modern learning theories applied to computer learning (search terms: 'learning theory' AND 'e-learning' OR 'web-based learning') for articles published between 1990 and 2012. The first search identified 29 studies, dominated in topic by the cognitive load, elaboration and scaffolding theories. The second search identified 139 studies, with diverse topics in connectivism, discovery and technical scaffolding. Based on their relative representation in the literature, the applications of these theories were collapsed into a list of CBTM design principles. Ten principles were identified and categorised into three levels of design: the global level (managing objectives, framing, minimising technical load); the rhetoric level (optimising modality, making modality explicit, scaffolding, elaboration, spaced repeating), and the detail level (managing text, managing devices). This review examined the literature in the application of learning theories to CAL to develop a set of principles that guide CBTM design. Further research will enable educators to

Introduction: In recent years, medical education has changed dramatically and many medical schools in the world have been trying for expand modern training methods. Purpose of the research is to appraise the medical students of teacher-based and student-based teaching methods in Infectious diseases course, in the Medical School of Hormozgan Medical Sciences University. Methods: In this interventional study, a total of 52 medical scholars that used Section in this Infectious diseases course were included. About 50% of this course was presented by a teacher-based teaching method (lecture) and 50% by a student-based teaching method (problem-based learning). The satisfaction of students regarding these methods was assessed by a questionnaire and a test was used to measure their learning. information are examined with using SPSS 19 and paired t-test. Results: The satisfaction of students of student-based teaching method (problem-based learning) was more positive than their satisfaction of teacher-based teaching method (lecture).The mean score of students in teacher-based teaching method was 12.03 (SD=4.08) and in the student-based teaching method it was 15.50 (SD=4.26) and where is a considerable variation among them (p<0.001). Conclusion: The use of the student-based teaching method (problem-based learning) in comparison with the teacher-based teaching method (lecture) to present the Infectious diseases course led to the student satisfaction and provided additional learning opportunities.

This book reflects the latest advances in nonlinear optics. Besides the simple, strict mathematical deduction, it also discusses the experimental verification and possible future applications, such as the all-optical switches. It consistently uses the practical unit system throughout. It employs simple physical images, such as "light waves" and "photons" to systematically explain the main principles of nonlinear optical effects. It uses the first-order nonlinear wave equation in frequency domain under the condition of “slowly varying amplitude approximation" and the classical model of the interaction between the light and electric dipole. At the same time, it also uses the rate equations based on the energy-level transition of particle systems excited by photons and the energy and momentum conservation principles to explain the nonlinear optical phenomenon. The book is intended for researchers, engineers and graduate students in the field of the optics, optoelectronics, fiber communication, information tech...

Development of geometry materials based on scientific approach for junior high school students

Nurafni; Siswanto, R. D.; Azhar, E.

2018-01-01

A scientific approach is a learning process designed so that learners can actively construct concepts, encourage learners to find out from various sources through observation, and not just be told. Therefore, learning by scientific approach offers a solution, because the goals, principles, and stages of the scientific approach allow for a good understanding of the students. Because of the absence of teaching materials “polyhedron geometry based on scientific approach” which is widely published in Indonesia, then we need to develop the teaching materials. The results obtained in this study are the tasks presented on teaching materials with a scientific approach both in defining the cube and the beam, identify and solve problems related to the properties and elements of cubes and beams, making cube and beam nets, solving problems related to cube and beam nets, solving problems related to cube and beam surface area. Beginning with the difficulties students face. Then, based on the results of interviews with teachers and analysis of student difficulties on each indicator, researchers revise the teaching materials as needed. Teaching materials that have not found any more student difficulties then the teaching materials are considered valid and ready for use by teachers and students.

2002-01-01

This study identifies the conceptual underpinnings of effective school-based drug education practice in light of contemporary research evidence and the practical experience of a broad range of drug education stakeholders. The research involved a review of the literature, a national survey of 210 Australian teachers and others involved in drug education, and structured interviews with 22 key Australian drug education policy stakeholders. The findings from this research have been distilled and presented as a list of 16 principles that underpin effective drug education. In broad terms, drug education should be evidence-based, developmentally appropriate, sequential, and contextual. Programs should be initiated before drug use commences. Strategies should be linked to goals and should incorporate harm minimization. Teaching should be interactive and use peer leaders. The role of the classroom teacher is central. Certain program content is important, as is social and resistance skills training. Community values, the social context of use, and the nature of drug harm have to be addressed. Coverage needs to be adequate and supported by follow-up. It is envisaged that these principles will provide all those involved in the drug education field with a set of up-to-date, research-based guidelines against which to reference decisions on program design, selection, implementation, and evaluation.

Health technology assessment (HTA) carried out for policy decision making has well-established principles unlike hospital-based HTA (HB-HTA), which differs from the former in the context characteristics and ways of operation. This study proposes principles for good practices in HB-HTA units. A framework for good practice criteria was built inspired by the EFQM excellence business model and information from six literature reviews, 107 face-to-face interviews, forty case studies, large-scale survey, focus group, Delphi survey, as well as local and international validation. In total, 385 people from twenty countries have participated in defining the principles for good practices in HB-HTA units. Fifteen guiding principles for good practices in HB-HTA units are grouped in four dimensions. Dimension 1 deals with principles of the assessment process aimed at providing contextualized information for hospital decision makers. Dimension 2 describes leadership, strategy and partnerships of HB-HTA units which govern and facilitate the assessment process. Dimension 3 focuses on adequate resources that ensure the operation of HB-HTA units. Dimension 4 deals with measuring the short- and long-term impact of the overall performance of HB-HTA units. Finally, nine core guiding principles were selected as essential requirements for HB-HTA units based on the expertise of the HB-HTA units participating in the project. Guiding principles for good practices set up a benchmark for HB-HTA because they represent the ideal performance of HB-HTA units; nevertheless, when performing HTA at hospital level, context also matters; therefore, they should be adapted to ensure their applicability in the local context.

Bicking Kinsey, Cara; Hupcey, Judith E

2013-12-01

to provide a principle-based analysis of the concept of maternal-infant bonding. principle-based method of concept analysis for which the data set included 44 articles published in the last decade from Pubmed, CINAHL, and PyschINFO/PsychARTICLES. literature inclusion criteria were English language, articles published in the last decade, peer-reviewed journal articles and commentary on published work, and human populations. after a brief review of the history of maternal-infant bonding, a principle-based concept analysis was completed to examine the state of the science with regard to this concept. The concept was critically examined according to the clarity of definition (epistemological principle), applicability of the concept (pragmatic principle), consistency in use and meaning (linguistic principle), and differentiation of the concept from related concepts (logical principle). Analysis of the concept revealed: (1) Maternal-infant bonding describes maternal feelings and emotions towards her infant. Evidence that the concept encompasses behavioural or biological components was limited. (2) The concept is clearly operationalised in the affective domain. (3) Maternal-infant bonding is linguistically confused with attachment, although the boundaries between the concepts are clearly delineated. despite widespread use of the concept, maternal-infant bonding is at times superficially developed and subject to confusion with related concepts. Concept clarification is warranted. A theoretical definition of the concept of maternal-infant bonding was developed to aid in the clarification, but more research is necessary to further clarify and advance the concept. nurse midwives and other practitioners should use the theoretical definition of maternal-infant bonding as a preliminary guide to identification and understanding of the concept in clinical practice.

The measurement of principled morality by the Kohlberg Moral Dilemma Questionnaire.

Science.gov (United States)

Heilbrun, A B; Georges, M

1990-01-01

The four stages preceding the postconventional level in the Kohlberg (1958, 1971, 1976) system of moral development are described as involving moral judgments that conform to external conditions of punishment, reward, social expectation, and conformity to the law. No special level of self-control seems necessary to behave in keeping with these conditions of external reinforcement. In contrast, the two stages of postconventional (principled) mortality involve defiance of majority opinion and defiance of the law--actions that would seem to require greater self-control. This study was concerned with whether postconventional moral reasoning, as measured by the Kohlberg Moral Dilemma Questionnaire (MDQ), can be associated with higher self-control. If so, prediction of principled moral behavior from the MDQ would be based not only on postconventional moral reasoning but bolstered by the necessary level of self-control as well. College students who came the closest to postconventional moral reasoning showed better self-control than college students who were more conventional or preconventional in their moral judgments. These results support the validity of the MDQ for predicting principled moral behavior.

Is principle based legislation smart choice for capital market’s regulation

Full Text Available Global financial crisis in 2008 posted numerous questions about the reasons and triggers. In past three years world’s economic literature has been full of academic articles analysing each reason or trigger and scientific explanations of possible connections. Majority outcome was, that key factor was excessive use of derivatives and synthetic financial products, which were under regulated or not regulated at all. The outcome was that countries with developed financial markets introduced new regulations and controls in the field of derivatives and synthetic financial products. Term “systemic risk” was introduced in global financial market. But will this approach really prevent such global crisis? Submission is divided in three parts. First part deals with the theory of principle based regulation. Principle based regulation was firstly introduced in UK and latter accepted by European Union in the field of capital markets. It was a way, together with the Lamfalussy process, to make EU regulation acceptable for all member states. Instead of detailed prescribed behaviour, legislation texts prescribe only desirable goals. Implementation is left to each state or, even worse, to each supervised subject. So the implementation should depend on the capital market’s development, capital product’s structure, tradition, investment companies’ size etc. From a distant view, principle based legislation could be seen as a great legislation writing’s technique. It could be seen as an effective solution to regulate a fast developing field without need to change the regulation. But is it true? Second part of the submission addresses the legal questions and problems, connected to the principle based regulation starting with the validity of regulations. Broad definitions in Market in financial instruments Directive (MiFID, introduced for fast adaptation to new financial products and instruments, are now turning into dinosaurs. Contrary to US’s fast

CCD-based thermoreflectance microscopy has emerged as a high resolution, non-contact imaging technique for thermal profiling and performance and reliability analysis of numerous electronic and optoelectronic devices at the micro-scale. This thermography technique, which is based on measuring the relative change in reflectivity of the device surface as a function of change in temperature, provides high-resolution thermal images that are useful for hot spot detection and failure analysis, mapping of temperature distribution, measurement of thermal transient, optical characterization of photonic devices and measurement of thermal conductivity in thin films. In this paper we review the basic physical principle behind thermoreflectance as a thermography tool, discuss the experimental setup, resolutions achieved, signal processing procedures and calibration techniques, and review the current applications of CCD-based thermoreflectance microscopy in various devices.

2011-02-10

To describe the development and assessment of monographs as an assignment to incorporate evidence-based medicine (EBM) and pharmacoeconomic principles into a third-year pharmacoeconomic course. Eight newly FDA-approved drugs were assigned to 16 teams of students, where each drug was assigned to 2 teams. Teams had to research their drug, write a professional monograph, deliver an oral presentation, and answer questions posed by faculty judges. One team was asked to present evidence for inclusion of the drug into a formulary, while another team presented evidence against inclusion. The teams' average score on the written report was 99.1%; on the oral presentation, 92.5%, and on the online quiz given at the end of the presentations, 77%. Monographs are a successful method of incorporating and integrating learning across different concepts, as well as increasing relevance of pharmacoeconomics in the PharmD curriculum.

Colonic transit time and pressure based on Bernoulli's principle.

Science.gov (United States)

Uno, Yoshiharu

2018-01-01

Variations in the caliber of human large intestinal tract causes changes in pressure and the velocity of its contents, depending on flow volume, gravity, and density, which are all variables of Bernoulli's principle. Therefore, it was hypothesized that constipation and diarrhea can occur due to changes in the colonic transit time (CTT), according to Bernoulli's principle. In addition, it was hypothesized that high amplitude peristaltic contractions (HAPC), which are considered to be involved in defecation in healthy subjects, occur because of cecum pressure based on Bernoulli's principle. A virtual healthy model (VHM), a virtual constipation model and a virtual diarrhea model were set up. For each model, the CTT was decided according to the length of each part of the colon, and then calculating the velocity due to the cecum inflow volume. In the VHM, the pressure change was calculated, then its consistency with HAPC was verified. The CTT changed according to the difference between the cecum inflow volume and the caliber of the intestinal tract, and was inversely proportional to the cecum inflow volume. Compared with VHM, the CTT was prolonged in the virtual constipation model, and shortened in the virtual diarrhea model. The calculated pressure of the VHM and the gradient of the interlocked graph were similar to that of HAPC. The CTT and HAPC can be explained by Bernoulli's principle, and constipation and diarrhea may be fundamentally influenced by flow dynamics.

A critique of the molecular target-based drug discovery paradigm based on principles of metabolic control: advantages of pathway-based discovery.

Science.gov (United States)

Hellerstein, Marc K

2008-01-01

Contemporary drug discovery and development (DDD) is dominated by a molecular target-based paradigm. Molecular targets that are potentially important in disease are physically characterized; chemical entities that interact with these targets are identified by ex vivo high-throughput screening assays, and optimized lead compounds enter testing as drugs. Contrary to highly publicized claims, the ascendance of this approach has in fact resulted in the lowest rate of new drug approvals in a generation. The primary explanation for low rates of new drugs is attrition, or the failure of candidates identified by molecular target-based methods to advance successfully through the DDD process. In this essay, I advance the thesis that this failure was predictable, based on modern principles of metabolic control that have emerged and been applied most forcefully in the field of metabolic engineering. These principles, such as the robustness of flux distributions, address connectivity relationships in complex metabolic networks and make it unlikely a priori that modulating most molecular targets will have predictable, beneficial functional outcomes. These same principles also suggest, however, that unexpected therapeutic actions will be common for agents that have any effect (i.e., that complexity can be exploited therapeutically). A potential operational solution (pathway-based DDD), based on observability rather than predictability, is described, focusing on emergent properties of key metabolic pathways in vivo. Recent examples of pathway-based DDD are described. In summary, the molecular target-based DDD paradigm is built on a naïve and misleading model of biologic control and is not heuristically adequate for advancing the mission of modern therapeutics. New approaches that take account of and are built on principles described by metabolic engineers are needed for the next generation of DDD.

In this brief essay, I describe my approach to the principles course. I emphasize three themes. First, in teaching microeconomics, the tools of welfare economics should play a larger role than they have in the past. Second, in teaching macroeconomics, classical ideas should play a larger role than they have in the past. Third, in teaching all parts of the course, we instructors should be sure to stress the important principles and be careful not to overwhelm students with an excess of details.

Cognitive overload can inhibit learning, and cognitive load theory-based instructional design principles can be used to optimize learning situations. This study aims to investigate the effect of implementing cognitive load theory-based design principles in virtual reality simulation training of mastoidectomy. Eighteen novice medical students received 1 h of self-directed virtual reality simulation training of the mastoidectomy procedure randomized for standard instructions (control) or cognitive load theory-based instructions with a worked example followed by a problem completion exercise (intervention). Participants then completed two post-training virtual procedures for assessment and comparison. Cognitive load during the post-training procedures was estimated by reaction time testing on an integrated secondary task. Final-product analysis by two blinded expert raters was used to assess the virtual mastoidectomy performances. Participants in the intervention group had a significantly increased cognitive load during the post-training procedures compared with the control group (52 vs. 41 %, p  = 0.02). This was also reflected in the final-product performance: the intervention group had a significantly lower final-product score than the control group (13.0 vs. 15.4, p  virtual reality surgical simulation training of novices.

If students are not customers, what are they?

Science.gov (United States)

D'Eon, M F; Harris, C

2000-12-01

The answers to questions about the relationship between faculty and students-including medical students-depend on an understanding of the nature of teaching and the underlying ethical principles of our society. The authors maintain that teaching is purposive, rational, communal, and moral. They assert that Western society is based on the values of liberal democracy and that the key ethical principles for the professions that are derived from those values are autonomy, standard of care, and respect for democratic institutions. There are three candidates for ethical models on which to base the relationship between students and faculty. Two of them (clientism and paternalism) the authors reject. The one that they favor (the fiduciary model) is based on mutual trust and respect, which both students and faculty have responsibilities to maintain. Using that model, the authors conclude that students are, in some aspects, customers of faculty. This student-centered approach is balanced by treating society and other faculty as customers as well. Pathologies in medical education attributed to clientism (such as an obsession with marks and overemphasis on memorization) existed well before medical students were purportedly being treated as customers; perhaps it is not the student who is "broken" but the system in which the student is made to function. Whether students are called customers, clients, knowledge workers, or simply students, faculty must involve them more in shaping their education and in dealing with enduring problems that profoundly affect their learning.

Student-centered and ability training-oriented curriculum reform in teaching Microcontroller Principles and Interface Techniques

2017-08-01

Courses are an important way of cultivating talents in college education. Advanced training schemes and the course system are implemented through course teaching. Advanced teaching notions and methods also rely on course teaching. Therefore, the quality of course teaching is the fundamental guarantor for grooming talent. The teachers of the course "Microcontroller Principles and Interface Techniques" in the Optical Science and Engineering College of Zhejiang University insist on course teaching becoming student centered and ability-training-oriented. They pay attention to students'all-round development in terms of learning ability, practical ability, innovation ability, and exploring spirit. They actively carried out course reforms in four aspects, namely teaching, learning, evaluation, and experimentation. This paper mainly introduced these reforms. First, the teaching method was reformed by introducing case analysis and the notion of a flipped classroom to shift the course focus from the teacher to the students. Second, the learning method was reformed through the use of techniques such as peer learning and project design to promote students' sense of enquiry and learning initiative. Third, the evaluation method was reformed through the use of process assessment and diversity evaluation to encourage students to develop logical thinking and a down-to-earth manner. Fourth, the experimentation method was reformed by introducing hierarchical content, process management, and diversification of examination to change students'learning attitude from "dependence, passivity, and imitation" to "independence, active involvement, and creation."In general, the teaching method reform promoted reforms in learning, evaluation, and experimentation methods and further improved the style of study. These reforms improved teachers' teaching abilities and enabled course teaching to transform from being teacher centered to student centered. Years of exploration and practice results have

Verrinder, Joy M; Ostini, Remo; Phillips, Clive J C

2016-01-01

Moral judgment in relation to animal ethics issues has rarely been investigated. Among the research that has been conducted, studies of veterinary students have shown greater use of reasoning based on universal principles for animal than human ethics issues. This study aimed to identify if this was unique to students of veterinary and other animal-related professions. The moral reasoning of first year students of veterinary medicine, veterinary technology, and production animal science was compared with that of students in non-animal related disciplines of human medicine and arts. All students (n = 531) completed a moral reasoning test, the VetDIT, with animal and human scenarios. When compared with reasoning on human ethics issues, the combined group of students evaluating animal ethics issues showed higher levels of Universal Principles reasoning, lower levels of Personal Interest reasoning and similar levels of Maintaining Norms reasoning. Arts students showed more personal interest reasoning than students in most animal-related programs on both animal and human ethics issues, and less norms-based reasoning on animal ethics issues. Medical students showed more norms-based reasoning on animal ethics issues than all of the animal-related groups. There were no differences in principled reasoning on animal ethics issues between program groups. This has implications for animal-related professions and education programs showing that students' preference for principled reasoning on animal ethics issues is not unique to animal-related disciplines, and highlighting the need to develop student (and professional) capacity to apply principled reasoning to address ethics issues in animal industries to reduce the risk of moral distress.

Beach, Dale L; Alvarez, Consuelo J

2015-12-01

Synthetic biology offers an ideal opportunity to promote undergraduate laboratory courses with research-style projects, immersing students in an inquiry-based program that enhances the experience of the scientific process. We designed a semester-long, project-based laboratory curriculum using synthetic biology principles to develop a novel sensory device. Students develop subject matter knowledge of molecular genetics and practical skills relevant to molecular biology, recombinant DNA techniques, and information literacy. During the spring semesters of 2014 and 2015, the Synthetic Biology Laboratory Project was delivered to sophomore genetics courses. Using a cloning strategy based on standardized BioBrick genetic "parts," students construct a "reporter plasmid" expressing a reporter gene (GFP) controlled by a hybrid promoter regulated by the lac-repressor protein (lacI). In combination with a "sensor plasmid," the production of the reporter phenotype is inhibited in the presence of a target environmental agent, arabinose. When arabinose is absent, constitutive GFP expression makes cells glow green. But the presence of arabinose activates a second promoter (pBAD) to produce a lac-repressor protein that will inhibit GFP production. Student learning was assessed relative to five learning objectives, using a student survey administered at the beginning (pre-survey) and end (post-survey) of the course, and an additional 15 open-ended questions from five graded Progress Report assignments collected throughout the course. Students demonstrated significant learning gains (p Biology Laboratory Project enhanced their understanding of molecular genetics. The laboratory project is highly adaptable for both introductory and advanced courses.

Recommendations to improve self-management support and health outcomes for people with chronic conditions in primary care settings are provided on the basis of expert opinion supported by evidence for practices and processes. Practices and processes that could improve self-management support in primary care were identified through a nominal group process. In a targeted search strategy, reviews and meta-analyses were then identifed using terms from a wide range of chronic conditions and behavioral risk factors in combination with Self-Care, Self-Management, and Primary Care. On the basis of these reviews, evidence-based principles for self-management support were developed. The evidence is organized within the framework of the Chronic Care Model. Evidence-based principles in 12 areas were associated with improved patient self-management and/or health outcomes: (1) brief targeted assessment, (2) evidence-based information to guide shared decision-making, (3) use of a nonjudgmental approach, (4) collaborative priority and goal setting, (5) collaborative problem solving, (6) self-management support by diverse providers, (7) self-management interventions delivered by diverse formats, (8) patient self-efficacy, (9) active followup, (10) guideline-based case management for selected patients, (11) linkages to evidence-based community programs, and (12) multifaceted interventions. A framework is provided for implementing these principles in three phases of the primary care visit: enhanced previsit assessment, a focused clinical encounter, and expanded postvisit options. There is a growing evidence base for how self-management support for chronic conditions can be integrated into routine health care.

How "moral" are the principles of biomedical ethics?--a cross-domain evaluation of the common morality hypothesis.

Science.gov (United States)

Christen, Markus; Ineichen, Christian; Tanner, Carmen

2014-06-17

The principles of biomedical ethics - autonomy, non-maleficence, beneficence, and justice - are of paradigmatic importance for framing ethical problems in medicine and for teaching ethics to medical students and professionals. In order to underline this significance, Tom L. Beauchamp and James F. Childress base the principles in the common morality, i.e. they claim that the principles represent basic moral values shared by all persons committed to morality and are thus grounded in human moral psychology. We empirically investigated the relationship of the principles to other moral and non-moral values that provide orientations in medicine. By way of comparison, we performed a similar analysis for the business & finance domain. We evaluated the perceived degree of "morality" of 14 values relevant to medicine (n1 = 317, students and professionals) and 14 values relevant to business & finance (n2 = 247, students and professionals). Ratings were made along four dimensions intended to characterize different aspects of morality. We found that compared to other values, the principles-related values received lower ratings across several dimensions that characterize morality. By interpreting our finding using a clustering and a network analysis approach, we suggest that the principles can be understood as "bridge values" that are connected both to moral and non-moral aspects of ethical dilemmas in medicine. We also found that the social domain (medicine vs. business & finance) influences the degree of perceived morality of values. Our results are in conflict with the common morality hypothesis of Beauchamp and Childress, which would imply domain-independent high morality ratings of the principles. Our findings support the suggestions by other scholars that the principles of biomedical ethics serve primarily as instruments in deliberated justifications, but lack grounding in a universal "common morality". We propose that the specific manner in which the principles

PRINCIPLES- AND RULES-BASED ACCOUNTING DEBATE. IMPLICATIONS FOR AN EMERGENT COUNTRY

Directory of Open Access Journals (Sweden)

Deaconu Adela

2011-07-01

Full Text Available By a qualitative analysis, this research observes whether a principles-based system or a mixed version of it with the rules-based system, applied in Romania - an emergent country - is appropriate taking into account the mentalities, the traditions, and other cultural elements that were typical of a rules-based system. We support the statement that, even if certain contextual variables are common to other developed countries, their environments significantly differ. To be effective, financial reporting must reflect the firm's context in which it is functioning. The research has a deductive approach based on the analysis of the cultural factors and their influence in the last years. For Romania it is argue a lower accounting professionalism associated with a low level of ambiguity tolerance. For the stage analysed in this study (after the year 2005 the professional reasoning - a proxy for the accounting professional behaviour - took into consideration the fiscal and legal requirements rather than the accounting principles and judgments. The research suggest that the Romanian accounting practice and the professionals are not fully prepared for a principles-based system environment, associated with the ability to find undisclosed events, facing ambiguity, identifying inferred relationships and using intuition, respectively working with uncertainty. We therefore reach the conclusion that in Romania institutional amendments affecting the professional expertise would be needed. The accounting regulations must be chosen with great caution and they must answer and/ or be adjusted, even if the process would be delayed, to national values, behaviour of companies and individual expertise and beliefs. Secondly, the benefits of applying accounting reasoning in this country may be enhanced through a better understanding of their content and through practical exercise. Here regulatory bodies may intervene for organizing professional training programs and acting

Transcranial electrical neuromodulation based on the reciprocity principle

Directory of Open Access Journals (Sweden)

Mariano eFernandez Corazza

2016-05-01

Full Text Available A key challenge in multi-electrode transcranial electrical stimulation (TES or transcranial direct current stimulation (tDCS is to find a current injection pattern that delivers the necessary current density at a target and minimizes it in the rest of the head, which is mathematically modelled as an optimization problem. Such an optimization with the Least Squares (LS or Linearly Constrained Minimum Variance (LCMV algorithms is generally computationally expensive and requires multiple independent current sources. Based on the reciprocity principle in electroencephalography (EEG and TES, it could be possible to find the optimal TES patterns quickly whenever the solution of the forward EEG problem is available for a brain region of interest. Here, we investigate the reciprocity principle as a guideline for finding optimal current injection patterns in TES that comply with safety constraints. We define four different trial cortical targets in a detailed seven-tissue finite element head model, and analyze the performance of the reciprocity family of TES methods in terms of electrode density, targeting error, focality, intensity, and directionality using the LS and LCMV solutions as the reference standards. It is found that the reciprocity algorithms show good performance comparable to the LCMV and LS solutions. Comparing the 128 and 256 electrode cases, we found that use of greater electrode density improves focality, directionality, and intensity parameters. The results show that reciprocity principle can be used to quickly determine optimal current injection patterns in TES and help to simplify TES protocols that are consistent with hardware and software availability and with safety constraints.

A key challenge in multi-electrode transcranial electrical stimulation (TES) or transcranial direct current stimulation (tDCS) is to find a current injection pattern that delivers the necessary current density at a target and minimizes it in the rest of the head, which is mathematically modeled as an optimization problem. Such an optimization with the Least Squares (LS) or Linearly Constrained Minimum Variance (LCMV) algorithms is generally computationally expensive and requires multiple independent current sources. Based on the reciprocity principle in electroencephalography (EEG) and TES, it could be possible to find the optimal TES patterns quickly whenever the solution of the forward EEG problem is available for a brain region of interest. Here, we investigate the reciprocity principle as a guideline for finding optimal current injection patterns in TES that comply with safety constraints.

Students built upon their knowledge of phase changes, immiscible mixture, and the relationship between vapor pressure and boiling point to complete a project of modifications steam distillation apparatus. The research method is a qualitative case study, which aims to describe how (1) the creative thinking skills of students emerged during six weeks of theproject, (2) students built steam distillation apparatus characteristics as the project product and (3) students response to the project-based learning model. The results showed that the students had successfully constructed a steam distillation apparatus using plastic kettle as steam generator and distillation flask. A Plastic tubewas used to drain water vapor from steam generator to distillation flask and to drain steam containing essential oil to the condenser. A biscuit tin filled with ice was used as a condenser. The time required until resulting distillate was fifteen minutes. The production of essential was conductive qualitatively by a very strong smell typical of essential oil and two phases of distillate. Throughout the project, students formulated the relevant and varied problem, formulated the goals, proposed the ideas of the apparatus and materials, draw apparatus design, constructed apparatus, tested apparatus, evaluated, and reported the project. Student response was generally positive. They were pleased, interested, more understanding the concepts and work apparatus principles, also implemented new ideas. These results indicate that project-based learning can develop students' creative thinking skills. Based on these results, it is necessary to conduct research and implemented project-based learning to other concepts.

The increasing complexity of medical curricula would benefit from adaptive computer supported collaborative learning systems that support study management using instructional design and learning object principles. However, to our knowledge, there are scarce reports regarding applications developed to meet this goal and encompass the complete medical curriculum. The aim of ths study was to develop and assess the usability of an adaptive computer supported collaborative learning system for medical students to manage study sessions. A study platform named ALERT STUDENT was built as a free web application. Content chunks are represented as Flashcards that hold knowledge and open ended questions. These can be created in a collaborative fashion. Multiple Flashcards can be combined into custom stacks called Notebooks that can be accessed in study Groups that belong to the user institution. The system provides a Study Mode that features text markers, text notes, timers and color-coded content prioritization based on self-assessment of open ended questions presented in a Quiz Mode. Time spent studying and Perception of knowledge are displayed for each student and peers using charts. Computer supported collaborative learning is achieved by allowing for simultaneous creation of Notebooks and self-assessment questions by many users in a pre-defined Group. Past personal performance data is retrieved when studying new Notebooks containing previously studied Flashcards. Self-report surveys showed that students highly agreed that the system was useful and were willing to use it as a reference tool. The platform employs various instructional design and learning object principles in a computer supported collaborative learning platform for medical students that allows for study management. The application broadens student insight over learning results and supports informed decisions based on past learning performance. It serves as a potential educational model for the medical

Full Text Available This study assesses the quality of distance learning (DL in higher education assessed by considering the Seven Principles of Good Practice (SPGP. The participants were 77 second-year students from the Computer and Instructional Technologies Program (CEIT of a Faculty of Education in Turkey. A questionnaire was developed in line with the SPGP and administered to collect data after 14 weeks of teaching. The author's observations were added to a discussion of the connections between student perspectives and the SPGP. The lessons were delivered in a virtual classroom. It is a synchronous online learning environment with online meetings, chat, forums, whiteboards, desktop sharing, document sharing and other online features. The analysis of the results of the questionnaire indicate that this questionnaire as it has been developed in this study can be effective in understanding and evaluating the perspectives of learners on the quality of distance learning in virtual classrooms. This study also presents some new evidence on the potential of virtual classrooms for teaching, learning and learner interaction. Finally, some suggestions regarding the expectations of distance learners were also provided for instructors who wish to utilize virtual classrooms in their teaching.

2016-12-01

Research has shown that web-based interventions concerning mental health can be effective, although there is a broad range in effect sizes. Why some interventions are more effective than others is not clear. Persuasive technology is one of the aspects which has a positive influence on changing attitude and/or behavior, and can contribute to better outcomes. According to the Persuasive Systems Design Model there are various principles that can be deployed. It is unknown whether the number and combinations of principles used in a web-based intervention affect the effectiveness. Another issue in web-based interventions is adherence. Little is known about the relationship of adherence on the effectiveness of web-based interventions. This study examines whether there is a relationship between the number and combinations of persuasive technology principles used in web-based interventions and the effectiveness. Also the influence of adherence on effectiveness of web-based interventions is investigated. This study elaborates on the systematic review by [37] and therefore the articles were derived from that study. Only web-based interventions were included that were intended to be used on more than one occasion and studies were excluded when no information on adherence was provided. 48 interventions targeted at mental health were selected for the current study. A within-group (WG) and between-group (BG) meta-analysis were performed and subsequently subgroup analyses regarding the relationship between the number and combinations of persuasive technology principles and effectiveness. The influence of adherence on the effectiveness was examined through a meta-regression analysis. For the WG meta-analysis 40 treatment groups were included. The BG meta-analysis included 19 studies. The mean pooled effect size in the WG meta-analysis was large and significant (Hedges' g=0.94), while for the BG meta-analysis this was moderate to large and significant (Hedges' g=0.78) in favor of

2018-01-01

Purpose Variations in the caliber of human large intestinal tract causes changes in pressure and the velocity of its contents, depending on flow volume, gravity, and density, which are all variables of Bernoulli’s principle. Therefore, it was hypothesized that constipation and diarrhea can occur due to changes in the colonic transit time (CTT), according to Bernoulli’s principle. In addition, it was hypothesized that high amplitude peristaltic contractions (HAPC), which are considered to be involved in defecation in healthy subjects, occur because of cecum pressure based on Bernoulli’s principle. Methods A virtual healthy model (VHM), a virtual constipation model and a virtual diarrhea model were set up. For each model, the CTT was decided according to the length of each part of the colon, and then calculating the velocity due to the cecum inflow volume. In the VHM, the pressure change was calculated, then its consistency with HAPC was verified. Results The CTT changed according to the difference between the cecum inflow volume and the caliber of the intestinal tract, and was inversely proportional to the cecum inflow volume. Compared with VHM, the CTT was prolonged in the virtual constipation model, and shortened in the virtual diarrhea model. The calculated pressure of the VHM and the gradient of the interlocked graph were similar to that of HAPC. Conclusion The CTT and HAPC can be explained by Bernoulli’s principle, and constipation and diarrhea may be fundamentally influenced by flow dynamics. PMID:29670388

Teaching recovery to medical students.

LENUS (Irish Health Repository)

Feeney, Larkin

2013-03-01

Community mental health services are evolving toward more holistic, patient-centered, recovery-based practices. This change necessitates an attitudinal shift from mental health workers, and training in recovery principles is helpful in achieving this change. Medical students often have narrow, doctor-centered concepts of mental health care. Traditional clinical placements in psychiatry do little to address this. We evaluated a recovery-focused teaching program for medical students in psychiatry.

Perez-Cruz, Angel; Stiharu, Ion; Dominguez-Gonzalez, Aurelio

2017-07-20

In recent years paper-based microfluidic systems have emerged as versatile tools for developing sensors in different areas. In this work; we report a novel physical sensing principle for the characterization of liquids using a paper-based hygro-mechanical system (PB-HMS). The PB-HMS is formed by the interaction of liquid droplets and paper-based mini-structures such as cantilever beams. The proposed principle takes advantage of the hygroscopic properties of paper to produce hygro-mechanical motion. The dynamic response of the PB-HMS reveals information about the tested liquid that can be applied to characterize certain properties of liquids. A suggested method to characterize liquids by means of the proposed principle is introduced. The experimental results show the feasibility of such a method. It is expected that the proposed principle may be applied to sense properties of liquids in different applications where both disposability and portability are of extreme importance.

Principle-based concept analysis: intentionality in holistic nursing theories.

Aghebati, Nahid; Mohammadi, Eesa; Ahmadi, Fazlollah; Noaparast, Khosrow Bagheri

2015-03-01

This is a report of a principle-based concept analysis of intentionality in holistic nursing theories. A principle-based concept analysis method was used to analyze seven holistic theories. The data included eight books and 31 articles (1998-2011), which were retrieved through MEDLINE and CINAHL. Erickson, Kriger, Parse, Watson, and Zahourek define intentionality as a capacity, a focused consciousness, and a pattern of human being. Rogers and Newman do not explicitly mention intentionality; however, they do explain pattern and consciousness (epistemology). Intentionality has been operationalized as a core concept of nurse-client relationships (pragmatic). The theories are consistent on intentionality as a noun and as an attribute of the person-intentionality is different from intent and intention (linguistic). There is ambiguity concerning the boundaries between intentionality and consciousness (logic). Theoretically, intentionality is an evolutionary capacity to integrate human awareness and experience. Because intentionality is an individualized concept, we introduced it as "a matrix of continuous known changes" that emerges in two forms: as a capacity of human being and as a capacity of transpersonal caring. This study has produced a theoretical definition of intentionality and provides a foundation for future research to further investigate intentionality to better delineate its boundaries. © The Author(s) 2014.

Full Text Available The main purpose of this paper is to provide an analysis that with the reconstruction of the contract that is based on sharing profits and losses it will form a model contract that has Islamic values, maslahat and justice. In the practice of sharia banking in Indonesia, the financing agreement based on the principle of profit and loss sharing in form standard does not fully reflect the characteristic of the contract. Approach used is legislation approach, conceptual approach and contract approach. Legal materials consist of primary legal materials and secondary legal materials. The study is helpful in practice sharia banking, namely the model of financing contract based on the principle of profit and sharing. Standard contracts in sharia banking serve as a form of legal frame that can be reconstructed. The characteristics of the contract is based on the principle of profit and loss sharing which state is that no one is justified to get a profit without having to bear the business risk.

The purpose of this study was to compare the clinical outcomes of classic massage to massage based on the tensegrity principle for patients with chronic idiopathic shoulder pain. Thirty subjects with chronic shoulder pain symptoms were divided into 2 groups, 15 subjects received classic (Swedish) massage to tissues surrounding the glenohumeral joint and 15 subjects received the massage using techniques based on the tensegrity principle. The tensegrity principle is based on directing treatment to the painful area and the tissues (muscles, fascia, and ligaments) that structurally support the painful area, thus treating tissues that have direct and indirect influence on the motion segment. Both treatment groups received 10 sessions over 2 weeks, each session lasted 20 minutes. The McGill Pain Questionnaire and glenohumeral ranges of motion were measured immediately before the first massage session, on the day the therapy ended 2 weeks after therapy started, and 1 month after the last massage. Subjects receiving massage based on the tensegrity principle demonstrated statistically significance improvement in the passive and active ranges of flexion and abduction of the glenohumeral joint. Pain decreased in both massage groups. This study showed increases in passive and active ranges of motion for flexion and abduction in patients who had massage based on the tensegrity principle. For pain outcomes, both classic and tensegrity massage groups demonstrated improvement. Copyright © 2013 National University of Health Sciences. Published by Mosby, Inc. All rights reserved.

Technological advances in the quality, availability and linkage potential of health data for research make the need to develop robust and effective information governance mechanisms more pressing than ever before; they also lead us to question the utility of governance devices used hitherto such as consent and anonymisation. This article assesses and advocates a principles-based approach, contrasting this with traditional rule-based approaches, and proposes a model of principled proportionate governance . It is suggested that the approach not only serves as the basis for good governance in contemporary data linkage but also that it provides a platform to assess legal reforms such as the draft Data Protection Regulation.

Laser-induced breakdown spectroscopy (LIBS) and the principle component analysis (PCA) were combined to study aluminum alloy classification in the present article. Classification experiments were done on thirteen different kinds of standard samples of aluminum alloy which belong to 4 different types, and the results suggested that the LIBS-PCA method can be used to aluminum alloy fast classification. PCA was used to analyze the spectrum data from LIBS experiments, three principle components were figured out that contribute the most, the principle component scores of the spectrums were calculated, and the scores of the spectrums data in three-dimensional coordinates were plotted. It was found that the spectrum sample points show clear convergence phenomenon according to the type of aluminum alloy they belong to. This result ensured the three principle components and the preliminary aluminum alloy type zoning. In order to verify its accuracy, 20 different aluminum alloy samples were used to do the same experiments to verify the aluminum alloy type zoning. The experimental result showed that the spectrum sample points all located in their corresponding area of the aluminum alloy type, and this proved the correctness of the earlier aluminum alloy standard sample type zoning method. Based on this, the identification of unknown type of aluminum alloy can be done. All the experimental results showed that the accuracy of principle component analyses method based on laser-induced breakdown spectroscopy is more than 97.14%, and it can classify the different type effectively. Compared to commonly used chemical methods, laser-induced breakdown spectroscopy can do the detection of the sample in situ and fast with little sample preparation, therefore, using the method of the combination of LIBS and PCA in the areas such as quality testing and on-line industrial controlling can save a lot of time and cost, and improve the efficiency of detection greatly.

Thermodynamic modeling of the Ca-Sn system based on finite temperature quantities from first-principles and experiment

International Nuclear Information System (INIS)

Ohno, M.; Kozlov, A.; Arroyave, R.; Liu, Z.K.; Schmid-Fetzer, R.

2006-01-01

The thermodynamic model of the Ca-Sn system was obtained, utilizing the first-principles total energies and heat capacities calculated from 0 K to the melting points of the major phases. Since the first-principles result for the formation energy of the dominating Ca 2 Sn intermetallic phase is drastically different from the reported experimental data, we performed two types of thermodynamic modeling: one based on the first-principles output and the other based on the experimental data. In the former modeling, the Gibbs energies of the intermetallic compounds were fully quantified from the first-principles finite temperature properties and the superiority of the former thermodynamic description is demonstrated. It is shown that it is the combination of finite temperature first-principle calculations and the Calphad modeling tool that provides a sound basis for identifying and deciding on conflicting key thermodynamic data in the Ca-Sn system

Internet-based guided self-help for university students with anxiety, depression and stress: a randomized controlled clinical trial.

Day, Victor; McGrath, Patrick J; Wojtowicz, Magdalena

2013-07-01

Anxiety, depression and stress, often co-occurring, are the psychological problems for which university students most often seek help. Moreover there are many distressed students who cannot, or choose not to, access professional help. The present study evaluated the efficacy of an internet-based guided self-help program for moderate anxiety, depression and stress. The program was based on standard cognitive behavior therapy principles and included 5 core modules, some of which involved options for focusing on anxiety and/or depression and/or stress. Trained student coaches provided encouragement and advice about using the program via e-mail or brief weekly phone calls. Sixty-six distressed university students were randomly assigned to either Immediate Access or a 6-week Delayed Access condition. Sixty-one percent of Immediate Access participants completed all 5 core modules, and 80% of all participants completed the second assessment. On the Depression, Anxiety and Stress Scales-21, Immediate Access participants reported significantly greater reductions in depression (ηp(2)=. 07), anxiety (ηp(2)=. 08) and stress (ηp(2)=. 12) in comparison to participants waiting to do the program, and these improvements were maintained at a six month follow-up. The results suggest that the provision of individually-adaptable, internet-based, self-help programs can reduce psychological distress in university students. Copyright © 2013 Elsevier Ltd.

From geometry to algebra and vice versa: Realistic mathematics education principles for analyzing geometry tasks

Science.gov (United States)

Jupri, Al

2017-04-01

In this article we address how Realistic Mathematics Education (RME) principles, including the intertwinement and the reality principles, are used to analyze geometry tasks. To do so, we carried out three phases of a small-scale study. First we analyzed four geometry problems - considered as tasks inviting the use of problem solving and reasoning skills - theoretically in the light of the RME principles. Second, we tested two problems to 31 undergraduate students of mathematics education program and other two problems to 16 master students of primary mathematics education program. Finally, we analyzed student written work and compared these empirical to the theoretical results. We found that there are discrepancies between what we expected theoretically and what occurred empirically in terms of mathematization and of intertwinement of mathematical concepts from geometry to algebra and vice versa. We conclude that the RME principles provide a fruitful framework for analyzing geometry tasks that, for instance, are intended for assessing student problem solving and reasoning skills.

Full Text Available This study reports on the development of a reading comprehension course based on Critical Pedagogy principles, and the result of its application on EFL learners' reading comprehension competence, their motivation to read English materials, their democratic attitudes towards their English classrooms, and also their attitudes towards the critical course. The present study is, in fact, a step forward to scrutinize the outcomes of the beginning phases of a dissertation which was intended to develop a tentative model of Critical Pedagogy for English language teaching practice in Iran. Sixty one sophomore students (in two groups were the participants of the present study. One group was randomly assigned to the control group (n=31 who received instruction based on the conventional method of teaching reading comprehension practiced in most reading comprehension courses in Iran, while the other one made the experimental group (n=30 who received instruction based on the Critical Pedagogy course. Results of the statistical analyses comparing the participants' performance on pre- and post-tests regarding reading comprehension, a questionnaire on motivation, and a democratic attitude questionnaire which were administered before and after the treatment, besides the qualitative data from a semi-structured interview, suggested that despite some problem issues rising while practicing the principles of Critical Pedagogy, the developed course proved to have a significant positive impact on EFL learners’ reading comprehension ability, developing a positive democratic attitude towards their English classroom and also their motivation towards reading English materials. Students’ attitude towards the critical reading comprehension course was also discussed in terms of four emerging themes driven out of the qualitative data analysis. The most important message, however, may be the applicability of Critical Pedagogy principles in Iran, which had been reported

Highly accurate symplectic element based on two variational principles

Science.gov (United States)

Qing, Guanghui; Tian, Jia

2018-02-01

For the stability requirement of numerical resultants, the mathematical theory of classical mixed methods are relatively complex. However, generalized mixed methods are automatically stable, and their building process is simple and straightforward. In this paper, based on the seminal idea of the generalized mixed methods, a simple, stable, and highly accurate 8-node noncompatible symplectic element (NCSE8) was developed by the combination of the modified Hellinger-Reissner mixed variational principle and the minimum energy principle. To ensure the accuracy of in-plane stress results, a simultaneous equation approach was also suggested. Numerical experimentation shows that the accuracy of stress results of NCSE8 are nearly the same as that of displacement methods, and they are in good agreement with the exact solutions when the mesh is relatively fine. NCSE8 has advantages of the clearing concept, easy calculation by a finite element computer program, higher accuracy and wide applicability for various linear elasticity compressible and nearly incompressible material problems. It is possible that NCSE8 becomes even more advantageous for the fracture problems due to its better accuracy of stresses.

Game Design Principles based on Human Error

Guilherme Zaffari

2016-03-01

Full Text Available This paper displays the result of the authors’ research regarding to the incorporation of Human Error, through design principles, to video game design. In a general way, designers must consider Human Error factors throughout video game interface development; however, when related to its core design, adaptations are in need, since challenge is an important factor for fun and under the perspective of Human Error, challenge can be considered as a flaw in the system. The research utilized Human Error classifications, data triangulation via predictive human error analysis, and the expanded flow theory to allow the design of a set of principles in order to match the design of playful challenges with the principles of Human Error. From the results, it was possible to conclude that the application of Human Error in game design has a positive effect on player experience, allowing it to interact only with errors associated with the intended aesthetics of the game.

Design Principles for Serious Video Games in Mathematics Education: From Theory to Practice

Directory of Open Access Journals (Sweden)

Konstantinos Chorianopoulos

2014-09-01

Full Text Available There is growing interest in the employment of serious video games in science education, but there are no clear design principles. After surveying previous work in serious video game design, we highlighted the following design principles: 1 engage the students with narrative (hero, story, 2 employ familiar gameplay mechanics from popular video games, 3 engage students into constructive trial and error game-play and 4 situate collaborative learning. As illustrated examples we designed two math video games targeted to primary education students. The gameplay of the math video games embeds addition operations in a seamless way, which has been inspired by that of classic platform games. In this way, the students are adding numbers as part of popular gameplay mechanics and as a means to reach the video game objective, rather than as an end in itself. The employment of well-defined principles in the design of math video games should facilitate the evaluation of learning effectiveness by researchers. Moreover, educators can deploy alternative versions of the games in order to engage students with diverse learning styles. For example, some students might be motived and benefited by narrative, while others by collaboration, because it is unlikely that one type of serious video game might fit all learning styles. The proposed principles are not meant to be an exhaustive list, but a starting point for extending the list and applying them in other cases of serious video games beyond mathematics and learning.

Tony Bailetti

2011-10-01

Full Text Available A student spinoff company strives to transform knowledge acquired by students into an income-generating business. This article outlines how a university can increase the number of spinoff companies created by its student entrepreneurs. Student spinoff companies are of interest to all forward-thinking universities, particularly those that support research and teaching programs in the field of entrepreneurship. The spinoff companies provide tangible evidence that students acquire viable entrepreneurial skills while studying at the university. In addition, student spinoff companies contribute to regional economic development, commercialize knowledge that otherwise would go undeveloped, help universities attain and expand their core missions, and increase the return on the investments in university R&D. University policies developed specifically for student spinoff companies significantly affect the growth potential of such ventures. This article provides a model and a set of principles that universities can use to support and increase the number of student entrepreneurs at their institutions. The model and principles are grounded in research findings and practical experience. In addition, the article suggests that universities adopt a results-based management approach to plan and deploy initiatives to support student entrepreneurs. The approach is widely used by government agencies interested in increasing the outcomes from their investments.

General principles of radiotherapy

International Nuclear Information System (INIS)

Easson, E.C.

1985-01-01

The daily practice of any established branch of medicine should be based on some acceptable principles. This chapter is concerned with the general principles on which the radiotherapy of the Manchester school is based. Though many radiotherapists in other centres would doubtless accept these principles, there are sufficiently wide differences in practice throughout the world to suggest that some therapists adhere to a fundamentally different philosophy. The authors believe it is important, especially for those beginning their formal training in radiotherapy, to subscribe to an internally consistent school of thought, employing methods of treatment for each type of lesion in each anatomical site that are based on accepted principles and subjected to continuous rigorous scrutiny to test their effectiveness. Not only must each therapeutic technique be evaluated, but the underlying principles too must be questioned if and when this seems indicated. It is a feature of this hospital that similar lesions are all treated by the same technique, so long as statistical evidence justifies such a policy. All members of the staff adhere to the accepted policy until or unless reliable reasons are adduced to change this policy

Riggs, Nathaniel; Tewari, Abha; Stigler, Melissa; Rodrigues, Lindsay; Arora, Monika; Khubchandani, Jagdish; Simmons, Rob; Pentz, Mary Ann

2013-11-01

Childhood obesity has recently been reported as a growing problem in low- and middle-income countries. One potential prevention strategy is to apply effective obesity prevention approaches from the United States and/or other Western countries into programs that can be implemented in developing countries such as India. The purpose of this study was to explore Indian students' perceptions of social-contextual factors related to obesity and whether they perceived a role for school-based obesity prevention. This study was conducted as a first step in a model to translate interventions from one culture to another. A total of 183 fourth- and fifth-grade students of middle socioeconomic status participated in focus group discussions. Analyses were guided by the essential principles of qualitative research and informed by social cognitive and social ecological theories. Results yielded five relevant themes: (a) student health behavior knowledge, (b) parental influence on health behavior, (c) school influence on health behavior, (d) media influence on health behavior, and (e) contexts for health promotion intervention. We found that students had moderate knowledge related to health behaviors (i.e., food intake and physical activity); that parents, schools, and the media are all important contributors to healthy and unhealthy behavior; and that schools can play an important role in the prevention of obesity. Results suggest that Indian middle socioeconomic status students are already moderately aware of the health benefits to nutritious food intake and physical activity, but parents, schools, and the media can influence unhealthy behaviors.

To evaluate pharmacy student perceptions of team-based learning (TBL) vs traditional lecture-based learning formats. First professional year pharmacy students (N=111) at two universities used TBL in different courses during different semesters (fall vs spring). Students completed a 22-item team perceptions instrument before and after the fall semester. A 14-item teaching style preference instrument was completed at the end of the spring semester. Data were analyzed using Wilcoxon signed rank test and Mann-Whitney U test. Students who experienced TBL in the fall and went back to traditional format in the spring reported improved perceptions of teams and preferred TBL format over a traditional format more than students who experienced a traditional format followed by TBL. Students at both universities agreed that the TBL format assists with critical-thinking, problem-solving, and examination preparation. Students also agreed that teams should consist of individuals with different personalities and learning styles. When building teams, faculty members should consider ways to diversify teams by considering different views, perspectives, and strengths. Offering TBL early in the curriculum prior to traditional lecture-based formats is better received by students, as evidenced by anecdotal reports from students possibly because it allows students time to realize the benefits and assist them in building teamwork-related skills.

A new method for multi-dimensional stellar structures is proposed in this study. As for stellar evolution calculations, the Heney method is the defacto standard now, but basically assumed to be spherical symmetric. It is one of the difficulties for deformed stellar-evolution calculations to trace the potentially complex movements of each fluid element. On the other hand, our new method is very suitable to follow such movements, since it is based on the Lagrange coordinate. This scheme is also based on the variational principle, which is adopted to the studies for the pasta structures inside of neutron stars. Our scheme could be a major break through for evolution calculations of any types of deformed stars: proto-planets, proto-stars, and proto-neutron stars, etc. (paper)

Zou, Xueli

2007-11-01

To help students develop the scientific abilities desired in the 21st century workplace, four different types of student design tasks—observation, verification, application, and investigation experiments—have been developed and implemented in our calculus-based introductory courses. Students working in small groups are engaged in designing and conducting their own experiments to observe some physical phenomena, test a physical principle, build a real-life device, solve a complex problem, or conduct an open-inquiry investigation. A preliminary study has shown that, probed by a performance-based task, the identified scientific abilities are more explicitly demonstrated by design-lab students than non-design lab students. In this paper, detailed examples of the design tasks and assessment results will be reported.

Development of a Knowledge Base of Ti-Alloys From First-Principles and Thermodynamic Modeling

Science.gov (United States)

Marker, Cassie

An aging population with an active lifestyle requires the development of better load-bearing implants, which have high levels of biocompatibility and a low elastic modulus. Titanium alloys, in the body centered cubic phase, are great implant candidates, due to their mechanical properties and biocompatibility. The present work aims at investigating the thermodynamic and elastic properties of bcc Tialloys, using the integrated first-principles based on Density Functional Theory (DFT) and the CALculation of PHAse Diagrams (CALPHAD) method. The use of integrated first-principles calculations based on DFT and CALPHAD modeling has greatly reduced the need for trial and error metallurgy, which is ineffective and costly. The phase stability of Ti-alloys has been shown to greatly affect their elastic properties. Traditionally, CALPHAD modeling has been used to predict the equilibrium phase formation, but in the case of Ti-alloys, predicting the formation of two metastable phases o and alpha" is of great importance as these phases also drastically effect the elastic properties. To build a knowledge base of Ti-alloys, for biomedical load-bearing implants, the Ti-Mo-Nb-Sn-Ta-Zr system was studied because of the biocompatibility and the bcc stabilizing effects of some of the elements. With the focus on bcc Ti-rich alloys, a database of thermodynamic descriptions of each phase for the pure elements, binary and Ti-rich ternary alloys was developed in the present work. Previous thermodynamic descriptions for the pure elements were adopted from the widely used SGTE database for global compatibility. The previous binary and ternary models from the literature were evaluated for accuracy and new thermodynamic descriptions were developed when necessary. The models were evaluated using available experimental data, as well as the enthalpy of formation of the bcc phase obtained from first-principles calculations based on DFT. The thermodynamic descriptions were combined into a database

2007-03-01

The size of introductory physics lectures often inhibits personal homework assistance and timely corrective feedback. Andes, an intelligent homework help system designed for two semesters of introductory physics, can fill this need by encouraging students to use sound problem solving techniques and providing immediate feedback on each step of a solution. On request, Andes provides principles-based hints based on previous student actions. A multi-year study at the U.S. Naval Academy demonstrates that students using Andes perform better than students working the same problems as graded pencil and paper homeworks. In addition, student attitude surveys show that Andes is preferred over other homework systems. These findings have implications for student attitudes toward, and mastery of, physics.

A Variation on Uncertainty Principle and Logarithmic Uncertainty Principle for Continuous Quaternion Wavelet Transforms

Directory of Open Access Journals (Sweden)

Mawardi Bahri

2017-01-01

Full Text Available The continuous quaternion wavelet transform (CQWT is a generalization of the classical continuous wavelet transform within the context of quaternion algebra. First of all, we show that the directional quaternion Fourier transform (QFT uncertainty principle can be obtained using the component-wise QFT uncertainty principle. Based on this method, the directional QFT uncertainty principle using representation of polar coordinate form is easily derived. We derive a variation on uncertainty principle related to the QFT. We state that the CQWT of a quaternion function can be written in terms of the QFT and obtain a variation on uncertainty principle related to the CQWT. Finally, we apply the extended uncertainty principles and properties of the CQWT to establish logarithmic uncertainty principles related to generalized transform.

"How do I say that?": Using communication principles to enhance medication therapy management instruction.

Denvir, Paul M; Cardone, Katie E; Parker, Wendy M; Cerulli, Jennifer

2018-02-01

Medication therapy management (MTM) is a comprehensive, patient-centered approach to improving medication use, reducing the risk of adverse events and improving medication adherence. Given the service delivery model and required outputs of MTM services, communication skills are of utmost importance. The objectives of this study were to identify and describe communication principles and instructional practices to enhance MTM training. Drawing on formative assessment data from interviews of both pharmacy educators and alumni, this article identifies and describes communication principles and instructional practices that pharmacy educators can use to enhance MTM training initiatives to develop student communication strategies. Analysis revealed five key communication challenges of MTM service delivery, two communication principles that pharmacy teachers and learners can use to address those challenges, and a range of specific strategies, derived from communication principles, that students can use when challenges emerge. Implications of the analysis for pharmacy educators and researchers are described. Proactive communication training provided during MTM advanced pharmacy practice experiences enabled students to apply the principles and instructional strategies to specific patient interactions during the advanced pharmacy practice experiences and in their post-graduation practice settings.

How “moral” are the principles of biomedical ethics? – a cross-domain evaluation of the common morality hypothesis

Science.gov (United States)

2014-01-01

Background The principles of biomedical ethics – autonomy, non-maleficence, beneficence, and justice – are of paradigmatic importance for framing ethical problems in medicine and for teaching ethics to medical students and professionals. In order to underline this significance, Tom L. Beauchamp and James F. Childress base the principles in the common morality, i.e. they claim that the principles represent basic moral values shared by all persons committed to morality and are thus grounded in human moral psychology. We empirically investigated the relationship of the principles to other moral and non-moral values that provide orientations in medicine. By way of comparison, we performed a similar analysis for the business & finance domain. Methods We evaluated the perceived degree of “morality” of 14 values relevant to medicine (n1 = 317, students and professionals) and 14 values relevant to business & finance (n2 = 247, students and professionals). Ratings were made along four dimensions intended to characterize different aspects of morality. Results We found that compared to other values, the principles-related values received lower ratings across several dimensions that characterize morality. By interpreting our finding using a clustering and a network analysis approach, we suggest that the principles can be understood as “bridge values” that are connected both to moral and non-moral aspects of ethical dilemmas in medicine. We also found that the social domain (medicine vs. business & finance) influences the degree of perceived morality of values. Conclusions Our results are in conflict with the common morality hypothesis of Beauchamp and Childress, which would imply domain-independent high morality ratings of the principles. Our findings support the suggestions by other scholars that the principles of biomedical ethics serve primarily as instruments in deliberated justifications, but lack grounding in a universal “common morality”.

Operationalizing Principle-Based Standards for Animal Welfare-Indicators for Climate Problems in Pig Houses.

Science.gov (United States)

Vermeer, Herman M; Hopster, Hans

2018-03-23

The Dutch animal welfare law includes so-called principle-based standards. This means that the objective is described in abstract terms, enabling farmers to comply with the law in their own way. Principle-based standards are, however, difficult for the inspection agency to enforce because strict limits are missing. This pilot project aimed at developing indicators (measurements) to assess the climate in pig houses, thus enabling the enforcement of principle-based standards. In total, 64 farms with weaners and 32 farms with growing-finishing pigs were visited. On each farm, a set of climate-related measurements was collected in six pens. For each of these measurements, a threshold value was set, and exceeding this threshold indicated a welfare risk. Farm inspections were carried out during winter and spring, thus excluding situations with heat stress. Assessment of the variation and correlation between measurements reduced the dataset from 39 to 12 measurements. Using a principal components analysis helped to select five major measurements as warning signals. The number of exceeded thresholds per pen and per farm was calculated for both the large (12) and small (five) sets of measurements. CO₂ and NH₃ concentrations were related to the outside temperature. On colder days, there was less ventilation, and thus CO₂ and NH₃ concentrations increased. Air quality, reflected in the CO₂ and NH₃ concentrations, was associated with respiratory problems. Eye scores were positively correlated with both pig and pen fouling, and pig and pen fouling were closely related. We selected five signal indicators: CO₂, NH₃, and tail and eye score for weaners and finishers, and added ear score for weaners and pig fouling for growing-finishing pigs. The results indicate that pig farms can be ranked based on five signal indicators related to reduced animal welfare caused by climatic conditions. This approach could be adopted to other principle-based standards for pigs as well

Investigating Students' Reasoning about Acid-Base Reactions

Acid-base chemistry is central to a wide range of reactions. If students are able to understand how and why acid-base reactions occur, it should provide a basis for reasoning about a host of other reactions. Here, we report the development of a method to characterize student reasoning about acid-base reactions based on their description of…

Derek Holton

2003-01-01

Full Text Available This paper describes a study, which explored students' responses and reactions to a Web-based tertiary statistics course supporting problem-based learning. The study was undertaken among postgraduate students in a Malaysian university. The findings revealed that the majority of the students were satisfied with their learning experience and achieved comparable learning outcomes to students in the face-to-face version of the course. Students appreciated the flexibility of anytime, anywhere learning. The majority of the students was motivated to learn and had adequate technical support to complete the course. Improvement in computer skills was an incidental learning outcome from the course. The student-student and student-teacher communication was satisfactory but a few students felt isolated learning in the Web environment. These students expressed a need for some face-to-face lectures. While the majority of the students saw value in learning in a problem-based setting, around a third of the students expressed no opinion on, or were dissatisfied with, the problem-based environment. They were satisfied with the group facilitators and learning materials but were unhappy with the group dynamics. Some of the students felt unable to contribute to or learn from the asynchronous Web-based conferences using problem-based approach. Some of the students were not punctual and were not prepared to take part in the Web-based conferences. The findings have suggested a need to explicitly design an organising strategy in the asynchronous Web-based conferences using problem-based approach to aid students in completing the problem-based learning process.

Virus-inspired design principles of nanoparticle-based bioagents.

Directory of Open Access Journals (Sweden)

Hongyan Yuan

Full Text Available The highly effectiveness and robustness of receptor-mediated viral invasion of living cells shed lights on the biomimetic design of nanoparticle(NP-based therapeutics. Through thermodynamic analysis, we elucidate that the mechanisms governing both the endocytic time of a single NP and the cellular uptake can be unified into a general energy-balance framework of NP-membrane adhesion and membrane deformation. Yet the NP-membrane adhesion strength is a globally variable quantity that effectively regulates the NP uptake rate. Our analysis shows that the uptake rate interrelatedly depends on the particle size and ligand density, in contrast to the widely reported size effect. Our model predicts that the optimal radius of NPs for maximal uptake rate falls in the range of 25-30 nm, and optimally several tens of ligands should be coated onto NPs. These findings are supported by both recent experiments and typical viral structures, and serve as fundamental principles for the rational design of NP-based nanomedicine.

Abstract: As the health care delivery landscape changes, medical schools must develop creative strategies for preparing future physicians to provide quality care in this new environment. Despite the growing prominence of the patient-centered medical home (PCMH as an effective model for health care delivery, few medical schools have integrated formal education on the PCMH into their curricula. Incorporating the PCMH model into medical school curricula is important to ensure that students have a comprehensive understanding of the different models of health care delivery and can operate effectively as physicians. The authors provide a detailed description of the process by which the Weill Cornell Community Clinic (WCCC, a student-run free clinic, has integrated PCMH principles into a service-learning initiative. The authors assessed patient demographics, diagnoses, and satisfaction along with student satisfaction. During the year after a PCMH model was adopted, 112 students and 19 licensed physicians volunteered their time. A review of the 174 patients seen from July 2011 to June 2012 found that the most common medical reasons for visits included management of hypertension, hyperlipidemia, diabetes, gastrointestinal conditions, arthritis, anxiety, and depression. During the year after the adoption of the PCMH model, 87

Folkins, John Wm; Brackenbury, Tim; Krause, Miriam; Haviland, Allison

2016-02-01

This article considers the potential benefits that applying design principles from contemporary video games may have on enhancing therapy experiences. Six principles of video game design are presented, and their relevance for enriching clinical experiences is discussed. The motivational and learning benefits of each design principle have been discussed in the education literature as having positive impacts on student motivation and learning and are related here to aspects of clinical practice. The essential experience principle suggests connecting all aspects of the experience around a central emotion or cognitive connection. The discovery principle promotes indirect learning in focused environments. The risk-taking principle addresses the uncertainties clients face when attempting newly learned skills in novel situations. The generalization principle encourages multiple opportunities for skill transfer. The reward system principle directly relates to the scaffolding of frequent and varied feedback in treatment. Last, the identity principle can assist clients in using their newly learned communication skills to redefine self-perceptions. These principles highlight areas for research and interventions that may be used to reinforce or advance current practice.

A survey of variational principles

International Nuclear Information System (INIS)

Lewins, J.D.

1993-01-01

The survey of variational principles has ranged widely from its starting point in the Lagrange multiplier to optimisation principles. In an age of digital computation, these classic methods can be adapted to improve such calculations. We emphasize particularly the advantage of basing finite element methods on variational principles, especially if, as maximum and minimum principles, these can provide bounds and hence estimates of accuracy. The non-symmetric (and hence stationary rather than extremum principles) are seen however to play a significant role in optimisation theory. (Orig./A.B.)

Mentoring medical students in your general practice.

Science.gov (United States)

Fraser, John

2016-05-01

Mentoring medical students in general practices is becoming more common in Australia due to formalised scholarship programs and informal approaches by students. This paper defines mentoring in Australian general practice. Practical suggestions are made on how to structure a mentorship program in your practice. Mentoring differs from leadership and teaching. It is a long-term relationship between a student and an experienced general practitioner. Avoiding summative assessment in mentorship is important to its success. Mentoring is about forming a safe place to confidentially discuss personal and professional issues between a mentor and student. This is based on defining roles and mutual trust. At the same time, students crave formative feedback. Unfortunately, present feedback models are based on teaching principles that can blur the differences between assessor, teacher and mentor. Mentorship can provide students with orientation and learning experiences so that they are prepared for practice as an intern.

Students have a low mathematical ability because they are used to learning to hear the teacher's explanation. For that students are given activities to sharpen his ability in math. One way to do that is to create discovery learning based work sheet. The development of this worksheet took into account specific student learning styles including in schools that have classified students based on multiple intelligences. The dominant learning styles in the classroom were intrapersonal and interpersonal. The purpose of this study was to discover students’ responses to the mathematics work sheets of the junior high school with a discovery learning approach suitable for students with Intrapersonal and Interpersonal Intelligence. This tool was developed using a development model adapted from the Plomp model. The development process of this tools consists of 3 phases: front-end analysis/preliminary research, development/prototype phase and assessment phase. From the results of the research, it is found that students have good response to the resulting work sheet. The worksheet was understood well by students and its helps student in understanding the concept learned.

Gimpel, Nora; Kindratt, Tiffany; Dawson, Alvin; Pagels, Patti

2018-04-01

Community-based participatory research (CBPR) and service-learning are unique experiential approaches designed to train medical students how to provide individualized patient care from a population perspective. Medical schools in the US are required to provide support for service-learning and community projects. Despite this requirement, few medical schools offer structured service-learning. We developed the Community Action Research Track (CART) to integrate population medicine, health promotion/disease prevention and the social determinants of health into the medical school curriculum through CBPR and service-learning experiences. This article provides an overview of CART and reports the program impact based on students' participation, preliminary evaluations and accomplishments. CART is an optional 4‑year service-learning experience for medical students interested in community health. The curriculum includes a coordinated longitudinal program of electives, community service-learning and lecture-based instruction. From 2009-2015, 146 CART students participated. Interests in public health (93%), community service (73%), primary care (73%), CBPR (60%) and community medicine (60%) were the top reasons for enrolment. Significant improvements in mean knowledge were found when measuring the principles of CBPR, levels of prevention, determining health literacy and patient communication strategies (all p's Projects were disseminated by at least 65 posters and four oral presentations at local, national and international professional meetings. Six manuscripts were published in peer-reviewed journals. CART is an innovative curriculum for training future physicians to be community-responsive physicians. CART can be replicated by other medical schools interested in offering a longitudinal CBPR and service-learning track in an urban metropolitan setting.

Although the role of theories in design research is recognized, we show that little attention has been paid on how to use theories when designing new artifacts. We introduce design principles as a new methodological approach to address this problem. Design principles extend the notion of design rationales that document how a design decision emerged. We extend the concept of design rationales by using theoretical hypotheses to support or object to design decisions. At the example of developing...

Manley, J.; Ellins, K. K.; Conte, M. H.

2011-12-01

In summer 2010, as a participant in the TXESS Revolution, a National Science Foundation (NSF)-sponsored professional development program for teachers in support of Earth and Space Science, I participated in a scientific research cruise led by Dr. Maureen Conte of the Bermuda Institute of Ocean Sciences (BIOS). The primary purpose of the cruise was to collect water samples from different ocean depths, make temperature and conductivity measurements, and retrieve biologic particle debris collection equipment deployed as part of the NSF-sponsored Oceanic Flux Program to measure particle fluxes in the deep Sargasso Sea. A secondary objective involved the collection of plastic debris floating within the sargassum grass trapped in the North Atlantic gyre in order to investigate plastic pollution. As a member of the science team I worked alongside of Dr. Conte, scientists and graduate students, giving me a personal experience to inspire my students' interest in the marine ecosystem. In the classroom, I used a Project Based Learning (PBL) approach to translate my experience and knowledge gained into productive learning for my students. With Project Based Learning, teams of students solve a real world, open-ended challenge problem through research and experimentation. In this Problem, the challenge was to design a virtual product to motivate ordinary people to change their habits regarding their use and improper disposal of plastics. Team products included websites, social network pages, and in-school announcements to create awareness about plastic pollution in the ocean. Fulfilling one of the basic principles of the PBL approach to provide student access to experts, cruise participant and University of North Carolina graduate student Bonnie Monteleone dedicated an entire day to speak with each of my classes about her experiences studying ocean plastics and answer their questions via SKYPE. In addition, Ms. Monteleone used her extensive contacts to post the best of my

Perfect Form: Variational Principles, Methods, and Applications in Elementary Physics

International Nuclear Information System (INIS)

Isenberg, C

1997-01-01

This short book is concerned with the physical applications of variational principles of the calculus. It is intended for undergraduate students who have taken some introductory lectures on the subject and have been exposed to Lagrangian and Hamiltonian mechanics. Throughout the book the author emphasizes the historical background to the subject and provides numerous problems, mainly from the fields of mechanics and optics. Some of these problems are provided with an answer, while others, regretfully, are not. It would have been an added help to the undergraduate reader if complete solutions could have been provided in an appendix. The introductory chapter is concerned with Fermat's Principle and image formation. This is followed by the derivation of the Euler - Lagrange equation. The third chapter returns to the subject of optical paths without making the link with a mechanical variational principle - that comes later. Chapters on the subjects of minimum potential energy, least action and Hamilton's principle follow. This volume provides an 'easy read' for a student keen to learn more about the subject. It is well illustrated and will make a useful addition to all undergraduate physics libraries. (book review)

Principles governing heart failure therapy re-examined relative to standard evidence-based medicine-driven guidelines.

2011-09-01

Although all aspects of clinical work nowadays are modified by the pervading influence of evidence-based medicine (EBM) and multiplicative guidelines, not many clinicians realize that the underlying premise of EBM-driven guidelines is a particular strain of consequentialist ideology. Subservience to this ideology has transformed modern medical practice, but there is a real risk of distorting good medical practice, of belittling clinical judgement, of disempowering clinicians, and subjecting patients to skewed medical reality and treatment options. With so many heart failure (HF) guidelines issued by various august bodies, it is therefore timely to reappraise principles governing modern HF therapy with a fresh examination of the hierarchy of medical imperatives, the role of alternatives to consequentialism including deontological principles in HF therapy. In addition, other ideology worth re-examining, aside from EBM, are the principle of appropriate definition of HF underlying therapeutic goals and the principle of prioritizing objectives of HF therapy. Even within standard EBM, there are many questions to reconsider: about what types of evidence are admissible, different interpretations of available evidence, emphasizing patient-centered outcome measures instead of randomized controlled trials quantifiable therapeutic outcomes, how to prescribe drugs for prognostic versus symptomatic benefits, and how to deliver HF therapy based on pathophysiological features through mechanistic considerations and not just confined to randomized controlled trials or meta-analytical statistical imperatives. Through re-examination of these fundamental principles of HF therapy, it is hoped that clinicians will be empowered to manage HF patients more holistically and better deliver HF therapies in the best interest of each individual patient.

Concordance behavior of TB management is a form of collaboration among doctors, personnel, and patients in treating TB. Approvalamong them could be achieved if credibility and policy occur. This study is aimed to analyze the influence of TB medical personnel’s concordance behaviour principle to patient obedience at primary health care in Medan.The design of this study was quasi experimental, focusing on interventional primary health care, which is those who applied concordance behaviour principle to non-interventionalprimary health care. The population is TB patients, starting from 18 years old, TB category I with positive Acid Fast Bacilli Smear Test (AFBST), and taking TB regimens at Medan. Seventy- four patients were selected to be samples. They had undergone interview based on validated concordance principle, knowledge, behavior, and treatment. Data were analyzed using chi- square. The percentage of knowledge, behavior of TB patient to the treatment is higher on interventional primary health care than noninterventional ones. Treatment awareness based on concordance principle is expected to planish DOTS-based TB programs.

The development of new technologies has provided medical education with the ability to enhance the student learning experience and meet the needs of changing curricula. Students quickly adapt to using multimedia learning resources, but these need to be well designed, learner-centred and interactive for students to become significantly engaged. One way to ensure that students become committed users and that resources become distinct elements of the learning cycle is to involve students in resource design and production. Such an approach enables resources to accommodate student needs and preferences, but also provides opportunities for them to develop their own teaching and training skills. The aim of the medical student research project was to design and produce an electronic resource that was focused on a particular anatomical region. The views of other medical students were used to decide what features were suitable for inclusion and the resulting package contained basic principles and clinical relevance, and used a variety of approaches such as images of cadaveric material, living anatomy movies and quizzes. The completed package was assessed using a survey matrix and found to compare well with commercially available products. Given the ever-diversifying arena of multimedia instruction and the ability of students to be fully conversant with technology, this project demonstrates that students are ideal participants and creators of multimedia resources. It is hoped that such an approach will help to further develop the skill base of students, but will also provide an avenue of developing packages that are student user friendly, and that are focused towards particular curricula requirements. © Blackwell Publishing Ltd 2012.

Ecosystem-based management in the Wadden Sea: Principles for the governance of knowledge

Science.gov (United States)

Giebels, Diana; van Buuren, Arwin; Edelenbos, Jurian

2013-09-01

The governance of the Wadden Sea has to contend with a complex interplay of social and ecological systems. Social systems tend to be characterized by pluralism of - often conflicting - norms and values, and ecological systems are characterized by high complexity and natural and human-induced variability, leading to unpredictable and nonlinear behavior. This highly volatile situation challenges traditional forms of management as well as traditional ways of organizing knowledge for decision-making processes. Ecosystem-based management approaches have been developed to find more effective, holistic, and evidence-based strategies to deal with the challenges of complex socio-ecological systems. They also require another way of dealing with (scientific) knowledge, the way it is produced and applied. In this paper, from the perspective of ecosystem-based management, we define the specific principles that apply to the way knowledge is mobilized and applied within decision-making processes. We illuminate these principles by examining three empirical cases of ecosystem-based management within, or related to, the Wadden Sea area. Finally, we reflect upon our findings and elaborate on the extent to which our theoretical framework is capable of describing and assessing the interaction between knowledge and decision making within ecosystem-based management approaches.

Conceptual understanding is one of the most important aspects in the study of Physics because of it useful to understand principles behind certain phenomenon which happened. An innovative method was needed to strengthen and enhance student's conceptual understanding, especially regarding the abstract subject such as magnetic field. For this reason, worksheet and exploration sheet based on PDEODE*E (Predict, Discuss, Explain, Observe, Discuss, Explore, and Explain) that uses Gauss Meter application as the smartphone technology has been designed to answer the problem. The magnetic field strength in different mediums is the physics subject which covered in this research. The research was conducted with the aim to know how effective smartphone technology-based PDEODE*E could be implemented as a physics learning strategy. The result of this research shows that students could show improvements in conceptual understanding that shown by the conclusion that was constructed during the learning process. Based on this result, PDEODE*E could become a solution to strengthen students' conceptual understanding regarding physics subject, especially those that requires abstract thinking. This result also has shown that the application ofsmartphone technology could be used to support physics learning processes in the classroom, such as Gauss Meter in this research which used to measure the magnetic field, Light Meter which could be used in the concept of light, and Harmonicity Meter for the context of the sound wave.

Identifying students' difficulties in learning concept of probability is important for teachers to prepare the appropriate learning processes and can overcome obstacles that may arise in the next learning processes. This study revealed the level of students' understanding of the concept of probability and identified their difficulties as a part of the epistemological obstacles identification of the concept of probability. This study employed a qualitative approach that tends to be the character of descriptive research involving 55 students of class XII. In this case, the writer used the diagnostic test of probability concept learning difficulty, observation, and interview as the techniques to collect the data needed. The data was used to determine levels of understanding and the learning difficulties experienced by the students. From the result of students' test result and learning observation, it was found that the mean cognitive level was at level 2. The findings indicated that students had appropriate quantitative information of probability concept but it might be incomplete or incorrectly used. The difficulties found are the ones in arranging sample space, events, and mathematical models related to probability problems. Besides, students had difficulties in understanding the principles of events and prerequisite concept.

Controlling Chaos in Neuron Based on Lasalle Invariance Principle

2011-01-01

A new control law is proposed to asymptotically stabilize the chaotic neuron system based on LaSalle invariant principle. The control technique does not require analytical knowledge of the system dynamics and operates without an explicit knowledge of the desired steady-state position. The well-known modified Hodgkin-Huxley (MHH) and Hindmarsh-Rose (HR) model neurons are taken as examples to verify the implementation of our method. Simulation results show the proposed control law is effective. The outcome of this study is significant since it is helpful to understand the learning process of a human brain towards the information processing, memory and abnormal discharge of the brain neurons.

Teaching Statistical Principles with a Roulette Simulation

Directory of Open Access Journals (Sweden)

Graham D Barr

2013-03-01

Full Text Available This paper uses the game of roulette in a simulation setting to teach students in an introductory Stats course some basic issues in theoretical and empirical probability. Using an Excel spreadsheet with embedded VBA (Visual Basic for Applications, one can simulate the empirical return and empirical standard deviation for a range of bets in Roulette over some predetermined number of plays. In particular, the paper illustrates the difference between different playing strategies by contrasting a low payout bet (say a bet on “red” and a high payout bet (say a bet on a particular number by considering the expected return and volatility associated with the bets. The paper includes an Excel VBA based simulation of the Roulette wheel where students can make bets and monitor the return on the bets for one play or multiple plays. In addition it includes a simulation of the casino house advantage for repeated multiple plays; that is, it allows students to see how casinos may derive a new certain return equal to the house advantage by entertaining large numbers of bets which will systematically drive the volatility of the house advantage down to zero. This simulation has been shown to be especially effective at theUniversityofCape Townfor teaching first year Statistics students the subtler points of probability, as well as encouraging discussions around the risk-return trade-off facing gamblers. The program has also been shown to be useful for teaching students the principles of theoretical and empirical probabilities as well as an understanding of volatility.

Full Text Available XML (Extensible Markup Language represents one of flexible platforms for processing enterprise documents. Its simple syntax and powerful software infrastructure for processing this type of documents is a guarantee for high interoperability of individual documents. XML is today one of technologies influencing all aspects of ICT area.In the paper questions and basic principles of reusing XML-based documents are described in the field of enterprise documents. If we use XML databases or XML data types for storing these types of documents then partial redundancy could be expected due to possible documents’ similarity. This similarity can be found especially in documents’ structure and also in documents’ content and its elimination is necessary part of data optimization.The main idea of the paper is focused to possibilities how to think about dividing complex XML docu­ments into independent fragments that can be used as standalone documents and how to process them.Conclusions could be applied within software tools working with XML-based structured data and documents as document management systems or content management systems.

Mach's principle and rotating universes

International Nuclear Information System (INIS)

King, D.H.

1990-01-01

It is shown that the Bianchi 9 model universe satisfies the Mach principle. These closed rotating universes were previously thought to be counter-examples to the principle. The Mach principle is satisfied because the angular momentum of the rotating matter is compensated by the effective angular momentum of gravitational waves. A new formulation of the Mach principle is given that is based on the field theory interpretation of general relativity. Every closed universe with 3-sphere topology is shown to satisfy this formulation of the Mach principle. It is shown that the total angular momentum of the matter and gravitational waves in a closed 3-sphere topology universe is zero

Nagmoti, Jyoti Mahantesh

2017-01-01

PowerPoint (PPT™) presentation has become an integral part of day-to-day teaching in medicine. Most often, PPT™ is used in its default mode which in fact, is known to cause boredom and ineffective learning. Research has shown improved short-term memory by applying multimedia principles for designing and delivering lectures. However, such evidence in medical education is scarce. Therefore, we attempted to evaluate the effect of multimedia principles on enhanced learning of parasitology. Second-year medical students received a series of lectures, half of the lectures used traditionally designed PPT™ and the rest used slides designed by Mayer's multimedia principles. Students answered pre and post-tests at the end of each lecture (test-I) and an essay test after six months (test-II) which assessed their short and long term knowledge retention respectively. Students' feedback on quality and content of lectures were collected. Statistically significant difference was found between post test scores of traditional and modified lectures (P = 0.019) indicating, improved short-term memory after modified lectures. Similarly, students scored better in test II on the contents learnt through modified lectures indicating, enhanced comprehension and improved long-term memory (P learning through multimedia designed PPT™ and suggested for their continued use. It is time to depart from default PPT™ and adopt multimedia principles to enhance comprehension and improve short and long term knowledge retention. Further, medical educators may be trained and encouraged to apply multimedia principles for designing and delivering effective lectures.

Full Text Available One of the prominent theory was the goal-setting theory which was widely been used in educational setting. It is an approach than can enhance the teaching and learning activities in the classroom. This is a report paper about a simple study of the implementation of the goal-setting principle in the classroom. A clinical data of the teaching and learning session was then analysed to address several issues highlighted. It is found that the goal-setting principles if understood clearly by the teachers can enhance the teaching and learning activities. Failed to see the needs of the session will revoke the students learning interest. It is suggested that goal-setting learning principles could become a powerful aid for the teachers in the classroom.

The principle of least action history and physics

CERN Document Server

Rojo, Alberto

2018-01-01

The principle of least action originates in the idea that, if nature has a purpose, it should follow a minimum or critical path. This simple principle, and its variants and generalizations, applies to optics, mechanics, electromagnetism, relativity, and quantum mechanics, and provides an essential guide to understanding the beauty of physics. This unique text provides an accessible introduction to the action principle across these various fields of physics, and examines its history and fundamental role in science. It includes - with varying levels of mathematical sophistication - explanations from historical sources, discussion of classic papers, and original worked examples. The result is a story that is understandable to those with a modest mathematical background, as well as to researchers and students in physics and the history of physics.

A Principle of Intentionality.

Science.gov (United States)

Turner, Charles K

2017-01-01

The mainstream theories and models of the physical sciences, including neuroscience, are all consistent with the principle of causality. Wholly causal explanations make sense of how things go, but are inherently value-neutral, providing no objective basis for true beliefs being better than false beliefs, nor for it being better to intend wisely than foolishly. Dennett (1987) makes a related point in calling the brain a syntactic (procedure-based) engine. He says that you cannot get to a semantic (meaning-based) engine from there. He suggests that folk psychology revolves around an intentional stance that is independent of the causal theories of the brain, and accounts for constructs such as meanings, agency, true belief, and wise desire. Dennett proposes that the intentional stance is so powerful that it can be developed into a valid intentional theory. This article expands Dennett's model into a principle of intentionality that revolves around the construct of objective wisdom. This principle provides a structure that can account for all mental processes, and for the scientific understanding of objective value. It is suggested that science can develop a far more complete worldview with a combination of the principles of causality and intentionality than would be possible with scientific theories that are consistent with the principle of causality alone.

Conduct a pilot trial testing whether a new cognitive-behavioral (CB) group prevention program that incorporated cognitive-dissonance change principles was feasible and appeared effective in reducing depressive symptoms and major depressive disorder onset relative to a brochure control condition in college students with elevated depressive symptoms. 59 college students (M age = 21.8, SD = 2.3; 68% female, 70% White) were randomized to the 6-session Change Ahead group or educational brochure control condition, completing assessments at pretest, posttest, and 3-month follow-up. Recruitment and screening methods were effective and intervention attendance was high (86% attended all 6 sessions). Change Ahead participants showed medium-large reductions in depressive symptoms at posttest (M d = 0.64), though the effect attenuated by 3-month follow-up. Incidence of major depression onset at 3-month follow-up was 4% for Change Ahead participants versus 13% (difference ns). Change Ahead appears highly feasible and showed positive indications of reduced acute phase depressive symptoms and MDD onset relative to a minimal intervention control in this initial pilot. Given the brevity of the intervention, its apparent feasibility, and the lack of evidence-based depression prevention programs for college students, continued evaluation of Change Ahead appears warranted.

Moral reasoning is a vital skill in the nursing profession. Teaching moral reasoning to students is necessary toward promoting nursing ethics. The aim of this study was to compare the effectiveness of problem-based learning and lecture-based methods in ethics education in improving (1) moral decision-making, (2) moral reasoning, (3) moral development, and (4) practical reasoning among nursing students. This is a repeated measurement quasi-experimental study. Participants and research context: The participants were nursing students in a University of Medical Sciences in west of Iran who were randomly assigned to the lecture-based (n = 33) or the problem-based learning (n = 33) groups. The subjects were provided nursing ethics education in four 2-h sessions. The educational content was similar, but the training methods were different. The subjects completed the Nursing Dilemma Test before, immediately after, and 1 month after the training. The data were analyzed and compared using the SPSS-16 software. Ethical considerations: The program was explained to the students, all of whom signed an informed consent form at the baseline. The two groups were similar in personal characteristics (p > 0.05). A significant improvement was observed in the mean scores on moral development in the problem-based learning compared with the lecture-based group (p ethics education enhances moral development among nursing students. However, further studies are needed to determine whether such method improves moral decision-making, moral reasoning, practical considerations, and familiarity with the ethical issues among nursing students.

Self-directed learning readiness of Asian students: students perspective on a hybrid problem based learning curriculum.

Leatemia, Lukas D; Susilo, Astrid P; van Berkel, Henk

2016-12-03

To identify the student's readiness to perform self-directed learning and the underlying factors influencing it on the hybrid problem based learning curriculum. A combination of quantitative and qualitative studies was conducted in five medical schools in Indonesia. In the quantitative study, the Self Directed Learning Readiness Scale was distributed to all students in all batches, who had experience with the hybrid problem based curriculum. They were categorized into low- and high -level based on the score of the questionnaire. Three focus group discussions (low-, high-, and mixed level) were conducted in the qualitative study with six to twelve students chosen randomly from each group to find the factors influencing their self-directed learning readiness. Two researchers analysed the qualitative data as a measure of triangulation. The quantitative study showed only half of the students had a high-level of self-directed learning readiness, and a similar trend also occurred in each batch. The proportion of students with a high level of self-directed learning readiness was lower in the senior students compared to more junior students. The qualitative study showed that problem based learning processes, assessments, learning environment, students' life styles, students' perceptions of the topics, and mood, were factors influencing their self-directed learning. A hybrid problem based curriculum may not fully affect the students' self-directed learning. The curriculum system, teacher's experiences, student's background and cultural factors might contribute to the difficulties for the student's in conducting self-directed learning.

Problem-based learning: Developing resilience in nursing students

Directory of Open Access Journals (Sweden)

Jih-Yuan Chen

2011-06-01

Full Text Available A society needs mature and confident nurse practitioners, who are able to think analytically and flexibly, recognize needs for further preparation, and willing to engage in self-development. Concern is raised regarding how educators will build the capacity of resilient students with a knowledge base and a minimum set of skills in responding to various issues and for engaging in self-reflection. Drawing on the framework of nursing competencies and global standards for the education of professional nurses, resilient students may contribute through their social competence, problem-solving ability, sense of purpose, and persistence in the process to achieve the goal of the project. Educators should know how to build the resilient attribute in students by encouraging them to engage in self-reflection. This article discusses four areas that help students build resilience from project-based learning of a small group: the impact of problem-based learning at clinical practice, project/problem-based learning, resilient nursing student, and developing nursing students’ resilience. Self-assessment to check the promoting skills for teaching in a problem-based learning program helps the faculty holding the empowerment to encourage or support the students to face the challenge within the small team.

Kirsch, Daniel J; Pinder-Amaker, Stephanie L; Morse, Charles; Ellison, Marsha L; Doerfler, Leonard A; Riba, Michelle B

2014-12-01

College students' need for mental health care has increased dramatically, leaving campus counseling and mental health centers struggling to meet the demand. This has led to the investigation and development of extra-center, population-based interventions. Student-to-student support programs are but one example. Students themselves are a plentiful, often-untapped resource that extends the reach of mental health services on campus. Student-to-student programs capitalize on students' natural inclination to assist their peers. A brief review of the prevalence and effects of mental disorders in the college population is provided, followed by a broad overview of the range of peer-to-peer programs that can be available on college campuses. Two innovative programs are highlighted: (1) a hospital- and community-based program, the College Mental Health Program (CMHP) at McLean Hospital, and 2) the Student Support Network (SSN) at Worcester Polytechnic Institute. The subsequent section reviews the literature on peer-to-peer programs for students with serious and persistent mental illness for which there is a small but generally positive body of research. This lack of an empirical basis in college mental health leads the authors to argue for development of broad practice-research networks.

PLAYGROUND: preparing students for the cyber battleground

Science.gov (United States)

Nielson, Seth James

2016-12-01

Attempting to educate practitioners of computer security can be difficult if for no other reason than the breadth of knowledge required today. The security profession includes widely diverse subfields including cryptography, network architectures, programming, programming languages, design, coding practices, software testing, pattern recognition, economic analysis, and even human psychology. While an individual may choose to specialize in one of these more narrow elements, there is a pressing need for practitioners that have a solid understanding of the unifying principles of the whole. We created the Playground network simulation tool and used it in the instruction of a network security course to graduate students. This tool was created for three specific purposes. First, it provides simulation sufficiently powerful to permit rigorous study of desired principles while simultaneously reducing or eliminating unnecessary and distracting complexities. Second, it permitted the students to rapidly prototype a suite of security protocols and mechanisms. Finally, with equal rapidity, the students were able to develop attacks against the protocols that they themselves had created. Based on our own observations and student reviews, we believe that these three features combine to create a powerful pedagogical tool that provides students with a significant amount of breadth and intense emotional connection to computer security in a single semester.

Shifting to Value-Based Principles in Sickness Insurance: Challenges in Changing Roles and Culture.

Science.gov (United States)

Ståhl, Christian; Andersson, Frieda

2018-02-12

Purpose Management principles in insurance agencies influence how benefits are administered, and how return to work processes for clients are managed and supported. This study analyses a change in managerial principles within the Swedish Sickness Insurance Agency, and how this has influenced the role of insurance officials in relation to discretion and accountability, and their relationship to clients. Methods The study is based on a qualitative approach comprising 57 interviews with officials and managers in four insurance offices. Results The reforms have led to a change in how public and professional accountability is defined, where the focus is shifted from routines and performance measurements toward professional discretion and the quality of encounters. However, the results show how these changes are interpreted differently across different layers of the organization, where New Public Management principles prevail in how line managers give feedback on and reward the work of officials. Conclusions The study illustrates how the introduction of new principles to promote officials' discretion does not easily bypass longstanding management strategies, in this case managing accountability through top-down performance measures. The study points out the importance for public organizations to reconcile new organizational principles with the current organizational culture and how this is manifested through managerial styles, which may be resistant to change. Promoting client-oriented and value-driven approaches in client work hence needs to acknowledge the importance of organizational culture, and to secure that changes are reflected in organizational procedures and routines.

Slamet Wahyudi Yulianto

2015-12-01

Full Text Available This study attempts to reveal how the use of critical pedagogy principles in teaching English as a Foreign Language (EFL reading facilitates students to think critically. Additionally, it investigates and elaborates the benefits and challenges of using critical pedagogy principles in teaching EFL reading. The three critical pedagogy principles used in this study were dialogic education, democratic classroom, and reading the world and the word. Critical thinking skills and dispositions expected to be performed by the participants were analysis and evaluation skills, open-mindedness, and making reasoned decision. This is a case study design which was conducted in the form of teaching program. The teaching program which consisted of eight meetings was given to 59 EFL sophomores in the Reading in Professional Context class at a private teacher education in Bandung. Data in the form of classroom talks and activities and students‟ responses as well as their critical thinking skills self-assessment were collected by using video recordings, observation notes, interview guideline, students‟ learning journals, and questionnaires. It is revealed that the teaching program has facilitated students to think critically by providing four categories of activity. They are (1 offering problematic topics and reading materials that are linked to the students‟ lives, (2 encouraging students to read between the lines, (3 distributing classroom power, and (4 creating space for students‟ voices to be heard. Meanwhile, there are two benefits of the teaching program, namely (1 language development and (2 new knowledge as well as experience acquisition. However, there are three major challenges in conducting the teaching program that are (1 the lack of classroom-friendly authentic controversial reading materials, (2 the passive culture, and (3 the unpredictable classroom.

Full Text Available Research Question (RQ: Future managers are faced daily with a variety of ethical dilemmas in traffic that need to be balanced by the interests of all participants. The question is whether a new innovative model of ethical principles could be developed that would increase road safety.Purpose: The a im is to raise the level of social responsibility and relationship of participants in traffic as well as warn all participants on the importance of safety. In addition, the purpose is to share suggestions to other researchers for further research studies in the area of increasing traffic safety.Method: We carried out a quantitative study (survey among first year post-graduate students studying at a higher education school focused on quality management in south-eastern Slovenia. The article presents five different ethical scenarios.Results: The participants have very similar views on judging individual ethical dilemmas. The desire to increase road safety, have led to new useful suggestions for further study of innovative new ethical principles in the field of safety, such as: no death victims annually, adequate road infrastructure, improved vehicle technology, video surveillance systems, and so on.Organization: Relevant authorities should promote models of ethical thinking and the introduction of codes of conduct at an early age. As such, the state, police, rescuers, fire departments, hospitals, and so on, would have fewer deaths due to serious traffic accidents.Society: By taking these results and further research suggestions into account, society would gain a new model that would be based on zero accidents annually.Originality: Research in the field of ethics and innovative ethical principles of traffic safety is limited. The article presents practical examples of ethical and moral decision-making that we encounter in daily traffic. But nothing much is done to make it better ("every day the same story".Limitations/Future Research: The research study

Einstein's Elevator in Class: A Self-Construction by Students for the Study of the Equivalence Principle

Science.gov (United States)

Kapotis, Efstratios; Kalkanis, George

2016-10-01

According to the principle of equivalence, it is impossible to distinguish between gravity and inertial forces that a noninertial observer experiences in his own frame of reference. For example, let's consider an elevator in space that is being accelerated in one direction. An observer inside it would feel as if there was gravity force pulling him toward the opposite direction. The same holds for a person in a stationary elevator located in Earth's gravitational field. No experiment enables us to distinguish between the accelerating elevator in space and the motionless elevator near Earth's surface. Strictly speaking, when the gravitational field is non-uniform (like Earth's), the equivalence principle holds only for experiments in elevators that are small enough and that take place over a short enough period of time (Fig. 1). However, performing an experiment in an elevator in space is impractical. On the other hand, it is easy to combine both forces on the same observer, i.e., gravity and a fictitious inertial force due to acceleration. Imagine an observer in an elevator that falls freely within Earth's gravitational field. The observer experiences gravity pulling him down while it might be said that the inertial force due to gravity acceleration g pulls him up. Gravity and inertial force cancel each other, (mis)leading the observer to believe there is no gravitational field. This study outlines our implementation of a self-construction idea that we have found useful in teaching introductory physics students (undergraduate, non-majors).

Quantum principles in field interactions

International Nuclear Information System (INIS)

Shirkov, D.V.

1986-01-01

The concept of quantum principle is intruduced as a principle whosee formulation is based on specific quantum ideas and notions. We consider three such principles, viz. those of quantizability, local gauge symmetry, and supersymmetry, and their role in the development of the quantum field theory (QFT). Concerning the first of these, we analyze the formal aspects and physical contents of the renormalization procedure in QFT and its relation to ultraviolet divergences and the renorm group. The quantizability principle is formulated as an existence condition of a self-consistent quantum version with a given mechanism of the field interaction. It is shown that the consecutive (from a historial point of view) use of these quantum principles puts still larger limitations on possible forms of field interactions

Radatz, Dana L; Wright, Emily M

2016-01-01

The majority of batterer intervention program (BIP) evaluations have indicated they are marginally effective in reducing domestic violence recidivism. Meanwhile, correctional programs used to treat a variety of offenders (e.g., substance users, violent offenders, and so forth) that adhere to the "principles of effective intervention" (PEI) have reported significant reductions in recidivism. This article introduces the PEI-the principles on which evidence-based practices in correctional rehabilitation are based-and identifies the degree to which they are currently integrated into BIPs. The case is made that batterer programs could be more effective if they incorporate the PEI. Recommendations for further integration of the principles into BIPs are also provided. © The Author(s) 2015.

This study investigated characteristics of medical teachers who have adopted student-centered teaching methods into their teaching. A 24-item questionnaire consisted of respondent backgrounds, his or her use of student-centered teaching methods, and awareness of the school's educational objectives and curricular principles was administered of faculty members at a private medical school in Korea. Descriptive statistics and chi-square analysis were conducted to compare faculty use of student-centered approaches across different backgrounds and awareness of curricular principles. Overall response rate was 70% (N=140/200), approximately 25% (n=34) of whom were using student-centered teaching methods. Distributions in the faculty use of student-centered teaching methods were significantly higher among basic sciences faculty (versus clinical sciences faculty), with teaching experiences of over 10 years (versus less than 10 years), and who were aware of the school's educational objectives and curricular principles. Our study indicates differences in medical faculty's practice of student-centered teaching across disciplines, teaching experiences, and their understanding of the school's educational objectives curricular principles. These findings have implications for faculty development and institutional support to better promote faculty use of student-centered teaching approaches.

Wang, Su; Liu, Xiufeng; Zhao, Yandong

2012-09-01

As the breadth and depth of economic reforms increase in China, growing attention is being paid to equalities in opportunities to learn science by students of various backgrounds. In early 2009, the Chinese Ministry of Education and Ministry of Science and Technology jointly sponsored a national survey of urban eighth-grade students' science literacy along with their family and school backgrounds. The present study focused on students' understanding of basic science concepts and principles (BSCP), a subset of science literacy. The sample analyzed included 3,031 students from 109 randomly selected classes/schools. Correlation analysis, one-way analysis of variance, and two-level linear regression were conducted. The results showed that having a refrigerator, internet, more books, parents purchasing books and magazines related to school work, higher father's education level, and parents' higher expectation of the education level of their child significantly predicted higher BSCP scores; having siblings at home, owning an apartment, and frequently contacting teachers about the child significantly predicted lower BSCP scores. At the school level, the results showed that being in the first-tier or key schools, having school libraries, science popularization galleries, computer labs, adequate equipment for teaching, special budget for teacher training, special budget for science equipment, and mutual trust between teachers and students significantly predicated higher BSCP scores; and having science and technology rooms, offering science and technology interest clubs, special budget for science curriculum development, and special budget for science social practice activities significantly predicted lower BSCP scores. The implications of the above findings are discussed.

An 'ADC-Memory' system based on a new principle in data access

International Nuclear Information System (INIS)

Pan Dajing; Wu Yongqing; Wang Shibo

1990-01-01

A new kind of 'ADC-Memory' (ADC-M) with real time correction of counting loss in dead time is now used in a multiuser data acquisition and processing system based on DUAL/68000 microcomputer. In data access, it replaces the 'DMA + 1' in classical MCA with the new method 'DMA + N', where N is weight factor of correction. The new method is based on the principle of virtual pulse generator. This method is superior to the correction by the software because the correction needn't take the computer time. Thus, this ADC-M can be used in the counting of high rate pulses

2015-01-01

Competency-based education is known to improve the match between educational performance and employment opportunities. This study examined the effects of competency-based education on the learning outcomes of undergraduate nursing students. The study used a quasi-experimental design. A convenience sample of 312 second-year undergraduate nursing students from northern and southern Taiwan participated in the study. The experimental group (n=163) received competency-based education and the control group received traditional instruction (n=149) in a medical-surgical nursing course. Outcome measures included students' scores on the Objective Structured Clinical Examination, Self-Evaluated Core Competencies Scale, Metacognitive Inventory for Nursing Students questionnaire, and academic performance. Students who received competency-based education had significantly higher academic performance in the medical-surgical nursing course and practicum than did the control group. Required core competencies and metacognitive abilities improved significantly in the competency-based education group as compared to the control group after adjusting for covariates. Competency-based education is worth implementing and may close the gap between education and the ever-changing work environment. Copyright © 2014 Elsevier Ltd. All rights reserved.

Good, Christopher J

2009-01-01

When students create teaching materials, learning can be enhanced. Therefore, a project was designed based on the traditional clinical case report and the chiropractic technique and principles curriculum at the University of Bridgeport College of Chiropractic. The objectives were to increase mastery in a clinical topic, increase awareness of different patient presentations and management options, and enhance information technology skills. Following lectures about the components of a case report and neurological reflexes related to visceral comorbidities and subluxation and joint dysfunction, students created a case report based on a template provided by the instructor. A survey gathered student perspectives on the exercise. More than 70% of the surveyed students felt the project was at least moderately helpful in improving understanding of a case report, the condition investigated, their clinical reasoning, and the ability to integrate information. Most felt that they improved their understanding of neurological reflexes, use of the literature, and the practice of evidence-based care. The majority believed that they identified weakness in knowledge, improved self-learning skills, and increased confidence in managing patients. Most enjoyed it at least somewhat and 70% agreed that the project should be continued. Many believed that they were better prepared for national boards and had improved their writing skills.

Maximum principles and sharp constants for solutions of elliptic and parabolic systems

CERN Document Server

Kresin, Gershon

2012-01-01

The main goal of this book is to present results pertaining to various versions of the maximum principle for elliptic and parabolic systems of arbitrary order. In particular, the authors present necessary and sufficient conditions for validity of the classical maximum modulus principles for systems of second order and obtain sharp constants in inequalities of Miranda-Agmon type and in many other inequalities of a similar nature. Somewhat related to this topic are explicit formulas for the norms and the essential norms of boundary integral operators. The proofs are based on a unified approach using, on one hand, representations of the norms of matrix-valued integral operators whose target spaces are linear and finite dimensional, and, on the other hand, on solving certain finite dimensional optimization problems. This book reflects results obtained by the authors, and can be useful to research mathematicians and graduate students interested in partial differential equations.

The Rethinking of the Economic Activity Based on Principles of Eco-Efficiency

Directory of Open Access Journals (Sweden)

Daniela VÎRJAN

2011-07-01

Full Text Available Drought, floods, damaging storms, heat waves, acid rain, climate changes are but a few of the consequences of human action upon the environment. Can we possibly live against the environment? The answer is NO, and as such we must run an economy which respects the principles of eco-efficiency because only so can economic progress go on. Green economy is a great opportunity for all of the world’s countries, and is a real economy which keeps the resource-needs and environment relation in balance, aims towards quality and not quantity, lays emphasis on regeneration, recycling, reuse and creativity. Eco-efficiency implies both innovation towards a high degree of product dematerialization, services and systems, alongside with greatly changing current production and consumption practices. If we produce based on the principle of eco-efficiency we can reduce the effects of the profound economic, ecological, socio-political and cultural-spiritual crisis which marks our planet and countries.

PROCESS-BASED LEARNING: TOWARDS THEORETICAL AND LECTURE-BASED COURSEWORK IN STUDIO STYLE

Directory of Open Access Journals (Sweden)

Hatem Ezzat Nabih

2010-07-01

Full Text Available This article presents a process-based learning approach to design education where theoretical coursework is taught in studio-style. Lecture-based coursework is sometimes regarded as lacking in challenge and broadening the gap between theory and practice. Furthermore, lecture-based curricula tend to be detached from the studio and deny students from applying their theoretically gained knowledge. Following the belief that student motivation is increased by establishing a higher level of autonomy in the learning process, I argue for a design education that links theory with applied design work within the studio setting. By synthesizing principles of Constructivist Learning and Problem-Based Learning, PBL students are given greater autonomy by being actively involved in their education. Accordingly, I argue for a studio setting that incorporates learning in studio style by presenting three design applications involving students in investigation and experimentation in order to self-experience the design process.

2014-01-01

Hundreds of validated evidence-based intervention programs (EBIP) aim to improve families' well-being; however, most are not broadly adopted. As an alternative diffusion strategy, we created wellness centers to reach families' everyday lives with a prevention framework. At two wellness centers, one in a middle-class neighborhood and one in a low-income neighborhood, popular local activity leaders (instructors of martial arts, yoga, sports, music, dancing, Zumba), and motivated parents were trained to be Family Mentors. Trainings focused on a framework that taught synthesized, foundational prevention science theory, practice elements, and principles, applied to specific content areas (parenting, social skills, and obesity). Family Mentors were then allowed to adapt scripts and activities based on their cultural experiences but were closely monitored and supervised over time. The framework was implemented in a range of activities (summer camps, coaching) aimed at improving social, emotional, and behavioral outcomes. Successes and challenges are discussed for (a) engaging parents and communities; (b) identifying and training Family Mentors to promote children and families' well-being; and (c) gathering data for supervision, outcome evaluation, and continuous quality improvement. To broadly diffuse prevention to families, far more experimentation is needed with alternative and engaging implementation strategies that are enhanced with knowledge harvested from researchers' past 30 years of experience creating EBIP. One strategy is to train local parents and popular activity leaders in applying robust prevention science theory, common practice elements, and principles of EBIP. More systematic evaluation of such innovations is needed.

The Leibniz principle in quantum logic

The principle of the identity of indiscernibles (Leibniz Principle) is investigated within the framework of the formal language of quantum physics, which is given by an orthomodular lattice. The authors show that the validity of this principle is based on very strong preconditions (concerning the existence of convenient predicates) which are given in the language of classical physics but which cannot be fulfilled in orthomodular quantum logic

Effect of scaffolding on helping introductory physics students solve quantitative problems involving strong alternative conceptions

Science.gov (United States)

Lin, Shih-Yin; Singh, Chandralekha

2015-12-01

It is well known that introductory physics students often have alternative conceptions that are inconsistent with established physical principles and concepts. Invoking alternative conceptions in the quantitative problem-solving process can derail the entire process. In order to help students solve quantitative problems involving strong alternative conceptions correctly, appropriate scaffolding support can be helpful. The goal of this study is to examine how different scaffolding supports involving analogical problem-solving influence introductory physics students' performance on a target quantitative problem in a situation where many students' solution process is derailed due to alternative conceptions. Three different scaffolding supports were designed and implemented in calculus-based and algebra-based introductory physics courses involving 410 students to evaluate the level of scaffolding needed to help students learn from an analogical problem that is similar in the underlying principles involved but for which the problem-solving process is not derailed by alternative conceptions. We found that for the quantitative problem involving strong alternative conceptions, simply guiding students to work through the solution of the analogical problem first was not enough to help most students discern the similarity between the two problems. However, if additional scaffolding supports that directly helped students examine and repair their knowledge elements involving alternative conceptions were provided, e.g., by guiding students to contemplate related issues and asking them to solve the targeted problem on their own first before learning from the analogical problem provided, students were more likely to discern the underlying similarities between the problems and avoid getting derailed by alternative conceptions when solving the targeted problem. We also found that some scaffolding supports were more effective in the calculus-based course than in the algebra-based

Supporting middle school students' construction of evidence-based arguments: Impact of and student interactions with computer-based argumentation scaffolds

Science.gov (United States)

Belland, Brian Robert

Middle school students have difficulty creating evidence-based arguments (EBAs) during problem-based learning (PBL) units due to challenges (a) adequately representing the unit's central problem (Ge & Land, 2004; Liu & Bera, 2005), (b) determining and obtaining the most relevant evidence (Pedersen & Liu, 2002-2003), and (c) synthesizing gathered information to construct a sound argument (Cho & Jonassen, 2002). I designed and developed the Connection Log to support middle school students in this process. This study addressed (1) the Connection Log's impact on (a) argument evaluation ability, and (b) group argument quality and (2) how and why middle school science students used the Connection Log. Four sections of a 7th-grade science class participated. Student groups selected a stakeholder position related to the Human Genome Project (HGP) and needed to decide on and promote a plan to use $3 million to further their position as pertains to the HGP. I randomly assigned one higher-achieving and one lower-achieving class to Connection Log or no Connection Log conditions. Students completed an argument evaluation test, and impact on argument evaluation ability was determined using nested ANOVA. Two graduate students, blind to treatment conditions, rated group arguments, and impact on group argument quality was determined using nested MANOVA. To determine how and why students used the Connection Log, I videotaped and interviewed one small group from each class in the experimental condition. I coded transcripts and generated themes, triangulating the two data sources with informal observations during all class sessions and what students wrote in the Connection Log. I detected no significant differences on claim, evidence, or connection of claim to evidence ratings of debate performances. However, students used the Connection Log to counter different difficulties, and I found a significant main effect of the Connection Log on argument evaluation ability, as well as a

Original science-based music and student learning

Science.gov (United States)

Smolinski, Keith

American middle school student science scores have been stagnating for several years, demonstrating a need for better learning strategies to aid teachers in instruction and students in content learning. It has also been suggested by researchers that music can be used to aid students in their learning and memory. Employing the theoretical framework of brain-based learning, the purpose of this study was to examine the impact of original, science-based music on student content learning and student perceptions of the music and its impact on learning. Students in the treatment group at a public middle school learned songs with lyrics related to the content of a 4-week cells unit in science; whereas an equally sized control group was taught the same material using existing methods. The content retention and learning experiences of the students in this study were examined using a concurrent triangulation, mixed-methods study. Independent sample t test and ANOVA analyses were employed to determine that the science posttest scores of students in the treatment group (N = 93) were significantly higher than the posttest scores of students in the control group (N = 93), and that the relative gains of the boys in the treatment group exceeded those of the girls. The qualitative analysis of 10 individual interviews and 3 focus group interviews followed Patton's method of a priori coding, cross checking, and thematic analysis to examine the perceptions of the treatment group. These results confirmed that the majority of the students thought the music served as an effective learning tool and enhanced recall. This study promoted social change because students and teachers gained insight into how music can be used in science classrooms to aid in the learning of science content. Researchers could also utilize the findings for continued investigation of the interdisciplinary use of music in educational settings.

Pedagogical principles underpinning undergraduate Nurse Education in the UK: A review.

Science.gov (United States)

Mackintosh-Franklin, Carolyn

2016-05-01

This review provides a contextual report of the current use of pedagogy in undergraduate nursing programmes run by Higher Education Institutes (HEIs) in the United Kingdom (UK). Pedagogy provides the framework for educators to add shape and structure to the educational process, and to support student learning and programme development. Traditionally nurse education has used a behaviourist approach focusing on learning outcomes and competency based education, although there is also increasing support for the cognitive/student learning focused pedagogic approach. The keywords andragogy, pedagogy and student centred learning were used in a systematic stepwise descriptive content analysis of the programme specifications and programme handbooks of 40 current undergraduate programme documents, leading to an undergraduate award and professional registration as a nurse. 42% (17) of documents contained reference to the words, pedagogy and student centred learning, whilst no documents used the word andragogy. Where identified, pedagogy was used in a superficial manner, with only three documents identifying a specific pedagogical philosophy: one HEI citing a value based curriculum and two HEIs referencing social constructionism. Nine HEIs made reference to student centred learning but with no additional pedagogic information. A review of teaching, learning and assessment strategies indicated no difference between the documented strategies used by HEIs when comparing those with an espoused pedagogy and those without. Although educational literature supports the use of pedagogic principles in curriculum design, this is not explicit in undergraduate nursing programme documentation, and suggests that nurse educators do not view pedagogy as important to their programmes. Instead programmes appear to be developed based on operational and functional requirements with a focus on acquisition of knowledge and skills, and the fitness to practice of graduates entering the nursing

Why internet-based education?

2014-01-01

This essay illustrates five ways that Internet-based higher education can capitalize on fundamental principles of learning. Internet-based education can enable better mastery through distributed (shorter, more frequent) practice rather than massed (longer, less frequent) practice; it can optimize performance because it allows students to learn at their peak time of their day; it can deepen memory because it requires cheat-proof assignments and tests; it can promote critical thinking because it necessitates intellectual winnowing and sifting; and it can enhance writing skills by requiring students to write frequently and for a broad audience.

Principle-based ethics and nurses' attitudes towards artificial feeding.

Science.gov (United States)

Day, L; Drought, T; Davis, A J

1995-02-01

Nurses often institute artificial feeding for patients who would otherwise starve. Recently, the courts in the United States have favoured withholding or withdrawing feedings from patients who currently refuse or previously gave some indication they would refuse artificial nutrition and hydration. This paper investigates under what circumstances nurses feel justified in withholding artificial nutrition and hydration. Structured interviews were conducted with 40 cancer care nurses from two sites, and 40 dementia care nurses from two sites. The interviews were based on two vignettes, one involving an alert patient with terminal cancer, the other a patient suffering end-stage Alzheimer's dementia, and were analysed for themes coinciding with principles of deontological ethics. Investigators found that autonomy, beneficence and non-maleficence most often guided nurses' decisions to withhold or implement artificial feeding.

The supplemental instruction program: Student perceptions of the learning environment and impact on student academic achievement in college science at California State University, San Marcos

Science.gov (United States)

Hizer, Suzanne Elizabeth

Higher education in science has been criticized and calls to increase student learning and persistence to degree has been recognized as a national problem by the Department of Education, the National Science Foundation, the National Research Council, and the National Academy of Sciences. One mode of academic assistance that may directly address this issue is the implementation of Supplemental Instruction (SI) in science courses. SI is a specific model of academic assistance designed to help students in historically difficult science classes master course content, thus increasing their academic achievement and retention. This study assessed the SI program at California State University, San Marcos, in supported science courses. Specifically, academic achievement based on final course grades were compared between SI participating and nonparticipating students, multiple affective factors were measured at the beginning and end of the semester, and students' perceptions of the classroom and SI session learning environments recorded. Overall, students who attended five or more SI sessions achieved higher final course grades. Students who chose to participate in SI had higher initial levels of responsibility and anxiety. Additionally, SI participants experienced a reduction in anxiety over the semester whereas nonparticipants experienced an increase in anxiety from beginning to the end of the semester. The learning environment of SI embodies higher levels of constructivist principles of active learning such as cooperation, cohesiveness, innovation, and personalization---with one exception for the physics course, which is a based on problem-based learning. Structural equation modeling of variables indicates that high self-efficacy at the end of the semester is directly related to high final course grades; this is mediated by cohesion in the classroom and the cooperation evidenced in SI sessions. These findings are elaborated by student descriptions of what happened in SI

Teaching Tree-Thinking to Undergraduate Biology Students.

Science.gov (United States)

Meisel, Richard P

2010-07-27

Evolution is the unifying principle of all biology, and understanding how evolutionary relationships are represented is critical for a complete understanding of evolution. Phylogenetic trees are the most conventional tool for displaying evolutionary relationships, and "tree-thinking" has been coined as a term to describe the ability to conceptualize evolutionary relationships. Students often lack tree-thinking skills, and developing those skills should be a priority of biology curricula. Many common student misconceptions have been described, and a successful instructor needs a suite of tools for correcting those misconceptions. I review the literature on teaching tree-thinking to undergraduate students and suggest how this material can be presented within an inquiry-based framework.

Maximum principle and convergence of central schemes based on slope limiters

KAUST Repository

Mehmetoglu, Orhan; Popov, Bojan

2012-01-01

A maximum principle and convergence of second order central schemes is proven for scalar conservation laws in dimension one. It is well known that to establish a maximum principle a nonlinear piecewise linear reconstruction is needed and a typical choice is the minmod limiter. Unfortunately, this implies that the scheme uses a first order reconstruction at local extrema. The novelty here is that we allow local nonlinear reconstructions which do not reduce to first order at local extrema and still prove maximum principle and convergence. © 2011 American Mathematical Society.

A structured policy review of the principles of professional self-regulation.

Science.gov (United States)

Benton, D C; González-Jurado, M A; Beneit-Montesinos, J V

2013-03-01

The International Council of Nurses (ICN) has, for many years, based its work on professional self-regulation on a set of 12 principles. These principles are research based and were identified nearly three decades ago. ICN has conducted a number of reviews of the principles; however, changes have been minimal. In the past 5-10 years, a number of authors and governments, often as part of the review of regulatory systems, have started to propose principles to guide the way regulatory frameworks are designed and implemented. These principles vary in number and content. This study examines the current policy literature on principle-based regulation and compares this with the set of principles advocated by the ICN. A systematic search of the literature on principle-based regulation is used as the basis for a qualitative thematic analysis to compare and contrast the 12 principles of self-regulation with more recently published work. A mapping of terms based on a detailed description of the principles used in the various research and policy documents was generated. This mapping forms the basis of a critique of the current ICN principles. A professional self-regulation advocated by the ICN were identified. A revised and extended set of 13 principles is needed if contemporary developments in the field of regulatory frameworks are to be accommodated. These revised principles should be considered for adoption by the ICN to underpin their advocacy work on professional self-regulation. © 2013 The Authors.

Technology in Note Taking and Assessment: The Effects of Congruence on Student Performance

Directory of Open Access Journals (Sweden)

Matthew E. Barrett

2014-01-01

Full Text Available This study examined the encoding specificity principle in relation to traditional and computer-based note taking and assessment formats in higher education. Students (N = 79 took lecture notes either by hand (n = 40 or by computer (n = 39 and then completed either a computer or a paper-based assessment. When note taking and assessment formats were congruent, students scored significantly higher on the assessment when compared to students whose note taking and assessment format were incongruent. These findings highlight the importance of research on how in-class technology may affect student performance, and suggest that faculty and administrators seek to coordinate and standardize the use of assessment and note taking technologies where possible.

EDUCATION IN SEARCH OF THE ADEQUACY PRINCIPLE

Y. V. Larin

2014-01-01

Full Text Available The paper discusses the acute methodology problem: elicitation of the fundamental principle of modern education. In the course of retrospective analysis, the author attempts to trace the essence and comparative historical specificity of the principle in question, and find out whether the currently declared one actually corresponds with the society demands and time requirements.Consequently, the author singles out three successive historical types of education, each of them based on the respective ideological and methodological assumptions. The first one (the 17th – mid-19th century, based on the ontological system of the «Man and Nature», regards the man as a natural creature and proclaims a fundamental educational principle of adequacy to nature. The second type, formed by the end of the 19th century and based on the ontological system of the «Man and Society», takes the man as a social creature and puts forward a fundamental educational principle of adequacy to society. And finally, the multi-dimensional ontological system of the «ManNature-Culture-Society», developed in the mid-20th century, defines the man as a bio-socio-cultural creature and forms a basis for a new fundamental educational principle of adequacy to culture.The paper maintains that the principle of adequacy to nature corresponds with the classical period of education history; orientation on the social adequacy represents its non-classical stage; and consequently, the principle of cultural adequacy signifies the post-non-classical phase. In conclusion, the author argues that resumption of the initial educational principle of adequacy to nature can be regarded as moving backward.

Basic principles simulators - concept training simulators

International Nuclear Information System (INIS)

Benkert, J.

1986-01-01

Basic Principles Simulators have the purpose of teaching general concepts, demonstrating and displaying the fundamental physical processes of a plant. They are used to illustrate theory to students and also to provide a preliminary training to the operators, to aquaint them with the basic dynamic interactions of the various systems during the normal operation of a plant, and to show the consequences of the most important and common transients and malfunctions. Basic principles simulators may vary in size from small desk cabinets to large panels. They represent with a certain detail the nuclear and thermohydraulic part of the plant. The availability of video displays allows to present detailed information about process parameters which are not shown on the control panels. In general the overall plant behaviour is represented well. Limitations are mostly found in the areas of logic and control. (orig./HP)

Full Text Available This study involved a class of serving teachers in their second year of a Bachelor of Education degree programme, in which one of the pre-requisite courses covered during first year was ‘Principles of Material Science (PMS. At the time of study, they were studying ‘Machine-shop Practice’ (MsP; a course based on the Design and Technology (D&T approach, in terms of teaching and learning. They were required to solve practical-technical problems through hands-on practical activities, supported by relevant ancillary theory. In practice, during such activities, students are expected to demonstrate the ability to apply their knowledge of Material Science (MS in various ways; for example, in the choice of materials for given projects aimed at solving specific problems and in the methods of working such materials. Now given this background, the problem was therefore to determine the extent to which students applied their knowledge of MS in solving selected problems under MsP. Data were gathered through interviews, discussions, observations and document analysis. Findings showed students being able to apply their knowledge of MS effectively during problem-solving under MsP; thereby, qualifying their learning as having been outcome-based in nature.

Measures of Coupling between Neural Populations Based on Granger Causality Principle.

Science.gov (United States)

Kaminski, Maciej; Brzezicka, Aneta; Kaminski, Jan; Blinowska, Katarzyna J

2016-01-01

This paper shortly reviews the measures used to estimate neural synchronization in experimental settings. Our focus is on multivariate measures of dependence based on the Granger causality (G-causality) principle, their applications and performance in respect of robustness to noise, volume conduction, common driving, and presence of a "weak node." Application of G-causality measures to EEG, intracranial signals and fMRI time series is addressed. G-causality based measures defined in the frequency domain allow the synchronization between neural populations and the directed propagation of their electrical activity to be determined. The time-varying G-causality based measure Short-time Directed Transfer Function (SDTF) supplies information on the dynamics of synchronization and the organization of neural networks. Inspection of effective connectivity patterns indicates a modular structure of neural networks, with a stronger coupling within modules than between them. The hypothetical plausible mechanism of information processing, suggested by the identified synchronization patterns, is communication between tightly coupled modules intermitted by sparser interactions providing synchronization of distant structures.

Personal profile of medical students selected through a knowledge-based exam only: are we missing suitable students?

2016-04-01

Full Text Available Introduction: A consistent body of literature highlights the importance of a broader approach to select medical school candidates both assessing cognitive capacity and individual characteristics. However, selection in a great number of medical schools worldwide is still based on knowledge exams, a procedure that might neglect students with needed personal characteristics for future medical practice. We investigated whether the personal profile of students selected through a knowledge-based exam differed from those not selected. Methods: Students applying for medical school (N=311 completed questionnaires assessing motivations for becoming a doctor, learning approaches, personality traits, empathy, and coping styles. Selection was based on the results of MCQ tests. Principal component analysis was used to draw a profile of the students. Differences between selected and non-selected students were examined by Multivariate ANOVAs, and their impact on selection by logistic regression analysis. Results: Students demonstrating a profile of diligence with higher conscientiousness, deep learning approach, and task-focused coping were more frequently selected (p=0.01. Other personal characteristics such as motivation, sociability, and empathy did not significantly differ, comparing selected and non-selected students. Conclusion: Selection through a knowledge-based exam privileged diligent students. It did neither advantage nor preclude candidates with a more humane profile.

Objective: Stimulating communication is an important workplace issue. We investigated the effects of a brief communication skills training (CST) program based on the principles of cognitive behavioral therapy (CBT). Methods: A randomized controlled trial was conducted on 206 white-collar workers. The intervention group underwent a 2-hour CST group training conducted by an occupational physician. Result: The results of the intention-to-treat analysis using a mixed-effects model showed that there was a significant interaction between group and time observed for the item “thinking together to solve problems and issues” (P = 0.02). The effect size (Cohen d) was 0.35 (95% confidence interval, 0.07 to 0.62). Conclusions: The present study suggests that a brief CST based on the principles of CBT could improve the communication behavior of workers. PMID:28045799
