    Full Text Available This work discusses investment funds in Croatia, with a particular emphasis on openend investment funds. After a short review of the development of the funds, the perception of the funds is analysed, as are the trends in total assets and in average yields. The degree of concentration of open-end investment funds is shown with statistical measures of concentration (the Gini Coefficient, the Lorenz Curve and concentration ratios. All these indicators show that the concentration is moderate to strong. The greatest yields are given by the equity funds, but these are also the most risky.

    2018-01-01

    Feedback deals with giving information to students related to their task which is done through score of their achievement, reaction, and comments. Considering its hierarchy, task difficulty level consists of low, middle and high levels. The difficulty level of open-ended questions is middle to high. Open-ended question is a good way to train students’ knowledge. This research is a descriptive research which aims at describing teacher’s learning management, students’ activities, students’ learning achievement, and students’ responses in mathematic learning using OEQGF. The subject was a teacher of mathematics who teaches eighth graders, and students themselves. The research design used is one shot case study. The result shows that: management learning has been very well implemented by the teacher; every students’ activity has been carried out by students; the students’ learning achievement have reached the criteria of completeness, and the students’ responses can be considered as positive. Therefore, it can be concluded that mathematic learning using OEQGF is effective.

  10. The Physics of Open Ended Evolution

    Adams, Alyssa M.

    What makes living systems different than non-living ones? Unfortunately this question is impossible to answer, at least currently. Instead, we must face computationally tangible questions based on our current understanding of physics, computation, information, and biology. Yet we have few insights into how living systems might quantifiably differ from their non-living counterparts, as in a mathematical foundation to explain away our observations of biological evolution, emergence, innovation, and organization. The development of a theory of living systems, if at all possible, demands a mathematical understanding of how data generated by complex biological systems changes over time. In addition, this theory ought to be broad enough as to not be constrained to an Earth-based biochemistry. In this dissertation, the philosophy of studying living systems from the perspective of traditional physics is first explored as a motivating discussion for subsequent research. Traditionally, we have often thought of the physical world from a bottom-up approach: things happening on a smaller scale aggregate into things happening on a larger scale. In addition, the laws of physics are generally considered static over time. Research suggests that biological evolution may follow dynamic laws that (at least in part) change as a function of the state of the system. Of the three featured research projects, cellular automata (CA) are used as a model to study certain aspects of living systems in two of them. These aspects include self-reference, open-ended evolution, local physical universality, subjectivity, and information processing. Open-ended evolution and local physical universality are attributed to the vast amount of innovation observed throughout biological evolution. Biological systems may distinguish themselves in terms of information processing and storage, not outside the theory of computation. The final research project concretely explores real-world phenomenon by means of

    Conceptual design studies on fusion reactors based upon open-ended confinement schemes, such as the tandem mirror and rf plugged cusp, have been carried out in Japan. These studies may be classified into two categories: near-term devices (Fusion Engineering Test Facility), and long-term fusion power recators. In the first category, a two-component cusp neutron source was proposed. In the second category, the GAMMA-R, a tandem-mirror power reactor, and the RFC-R, an axisymetric mirror and cusp, reactor studies are being conducted at the University of Tsukuba and the Institute of Plasma Physics. Mirror Fusion Engineering Facility parameters and a schematic are shown. The GAMMA-R central-cell design schematic is also shown

    Differentiating characteristics of magnetic confinement systems having externally generated magnetic fields that are ''open'' are listed and discussed in the light of their several potential advantages for fusion power systems. It is pointed out that at this stage of fusion research ''high-Q'' (as deduced from long energy confinement times) is not necessarily the most relevant criterion by which to judge the potential of alternate fusion approaches for the economic generation of fusion power. An example is given of a hypothetical open-geometry fusion power system where low-Q operation is essential to meeting one of its main objectives (low neutron power flux)

    2014-01-01

    Introduction There are few studies on the experiences of spouses of military members, with most focused on adverse impacts of deployment. Responses to an open-ended question in a survey of spouses' health and wellbeing enabled access to perceptions and insights on a broad range of topics. The objective of this investigation was to examine how respondents used the open-ended question and what they discussed, in aim of informing support service agencies and spouses of military members. Methods Thematic analysis was conducted on responses to the open-ended question. Descriptive analysis was performed on the demographics, military member characteristics and self-reported health of respondents and non-respondents to the open-ended question. Findings Over a quarter (28.5%) of the 1,332 survey participants answered the open-ended question, with respondents having a significantly higher level of education than non–respondents. Respondents expressed negative and positive experiences and insights on military life, provided personal information, commented on the survey, and qualified their responses to closed-ended questions. Topics included ‘inadequate support’, ‘deployment impacts’, ‘suggestions for supporting agencies’, ‘appraisal of experiences’ and ‘coping strategies’. Conclusions This investigation uncovered issues of importance to spouses of military members that were not included or identified in a quantitative study. The findings provide a platform from which to explore these issues further, particularly the impact of military life on the non-serving spouse's career. The findings also provide support agencies with evidence to strengthen their services and they give spouses an opportunity to reflect on their own and others' feelings and evaluations of military life.

  17. Semi-automated categorization of open-ended questions

    Full Text Available Text data from open-ended questions in surveys are difficult to analyze and are frequently ignored. Yet open-ended questions are important because they do not constrain respondents’ answer choices. Where open-ended questions are necessary, sometimes multiple human coders hand-code answers into one of several categories. At the same time, computer scientists have made impressive advances in text mining that may allow automation of such coding. Automated algorithms do not achieve an overall accuracy high enough to entirely replace humans. We categorize open-ended questions soliciting narrative responses using text mining for easy-to-categorize answers and humans for the remainder using expected accuracies to guide the choice of the threshold delineating between “easy” and “hard”. Employing multinomial boosting avoids the common practice of converting machine learning “confidence scores” into pseudo-probabilities. This approach is illustrated with examples from open-ended questions related to respondents’ advice to a patient in a hypothetical dilemma, a follow-up probe related to respondents’ perception of disclosure/privacy risk, and from a question on reasons for quitting smoking from a follow-up survey from the Ontario Smoker’s Helpline. Targeting 80% combined accuracy, we found that 54%-80% of the data could be categorized automatically in research surveys.

    Post, R.F.; Ryutov, D.D.

    1995-05-01

    Magnetic confinement systems that use externally generated magnetic fields can be divided topologically into two classes: ''closed'' and 'open''. The tokamak, the stellarator, and the reversed-field-pinch approaches are representatives of the first category, while mirror-based systems and their variants are of the second category. While the recent thrust of magnetic fusion research, with its emphasis on the tokamak, has been concentrated on closed geometry, there are significant reasons for the continued pursuit of research into open-ended systems. The paper discusses these reasons, reviews the history and the present status of open-ended systems, and suggests some future directions for the research

    1989-01-01

    Percutaneous transvenous treatment has become the elective therapy for varicocele because it is a simple, safe, economic and reliable procedure. The presence of proximal anastomoses connecting a competent valved spermatic trunk with the renal vein can be responsible for a varicocele and make its treatment difficult. In such cases, the valve of the spermatic venous trunk can be bypassed using an open-ended guidewire with a removable mandril core, and then injecting the sclerosing agent through the guide. Moreover, the guidewire can facilitate the insertion of catheter through the competent valve, thus allowing the placement of Gianturco coils. During the past 12 months the authors have successfully treated 4 patients affected by varicocele with competent valved venous trunk using the open-ended guidewire

  9. A Computational Analysis Model for Open-ended Cognitions

    Science.gov (United States)

    Morita, Junya; Miwa, Kazuhisa

    In this paper, we propose a novel usage for computational cognitive models. In cognitive science, computational models have played a critical role of theories for human cognitions. Many computational models have simulated results of controlled psychological experiments successfully. However, there have been only a few attempts to apply the models to complex realistic phenomena. We call such a situation ``open-ended situation''. In this study, MAC/FAC (``many are called, but few are chosen''), proposed by [Forbus 95], that models two stages of analogical reasoning was applied to our open-ended psychological experiment. In our experiment, subjects were presented a cue story, and retrieved cases that had been learned in their everyday life. Following this, they rated inferential soundness (goodness as analogy) of each retrieved case. For each retrieved case, we computed two kinds of similarity scores (content vectors/structural evaluation scores) using the algorithms of the MAC/FAC. As a result, the computed content vectors explained the overall retrieval of cases well, whereas the structural evaluation scores had a strong relation to the rated scores. These results support the MAC/FAC's theoretical assumption - different similarities are involved on the two stages of analogical reasoning. Our study is an attempt to use a computational model as an analysis device for open-ended human cognitions.

  14. Vortex formation at the open end of an acoustic waveguide

    Martinez Del Rio, Leon; Rendon, Pablo L.; Malaga, Carlos; Zenit, Roberto

    2017-11-01

    For high enough levels of acoustic pressure inside a cylindrical tube, a nonlinear mechanism is responsible for the formation of annular vortices at the open end of the tube, which results in energy loss. Higher sound pressure levels in the tube lead, in turn, to larger values of the acoustic velocity at the exit, and thus to higher Reynolds numbers. It has been observed [Buick et al., 2011] that, provided the magnitude of the acoustic velocity is large enough, two nonlinear regimes are possible: in the first regime, the vorticity appears only in the immediate vicinity of the tube; for higher velocities, vortex rings are formed at the open end of the tube and are advected outwards. We use a Lattice Boltzmann Method (LBM) to simulate the velocity and the pressure fields at the exit of the tube in 3D, with Reynolds numbers based on the acoustic boundary layer thickness 18 >Rδ > 1.8 . We also conduct experiments with phase-locked particle image velocimetry (PL-PIV) 2D within a range of 25.5 >Rδ > 10.2 . Experimental and numerical results are compared for a range of Womersley numbers. The effects of varying both the tube geometry and the end shape are addressed.

    2015-01-01

    In this work we study on a 2D square lattice a recent version of the Naming Game, an agent-based model used for describing the emergence of linguistic structures. The system is open-ended and agents can invent new words throughout the evolution of the game, picking them up from a pool characterised by a Gaussian distribution with standard deviation σ. The model displays a nonequilibrium phase transition at a critical point σ c  ≈ 25.6, which separates an absorbing consensus state from an active fragmented state where agents continuously exchange different words. The finite-size scaling analysis of our simulations strongly suggests that the phase transition is discontinuous. (paper)

    SAMEER RANJAN SAHU

    2017-02-01

    Full Text Available The main approach behind the present numerical investigation is to estimate the mass flow rate of air sucked into a horizontal open-ended louvered pipe from the surrounding atmosphere. The present numerical investigation has been performed by solving the conservation equations for mass, momentum and energy along with two equation based k-ɛ model for a louvered horizontal cylindrical pipe by finite volume method. It has been found from the numerical investigation that mass suction rate of air into the pipe increases with increase in louvered opening area and the number of nozzles used. Keeping other parameters fixed, for a given mass flow rate there exists an optimum protrusion of nozzle for highest mass suction into the pipe. It was also found from the numerical investigation that increasing the pipe diameter the suction mass flow rate of air was increased.

  18. Microwave corrosion detection using open ended rectangular waveguide sensors

    2000-02-01

    The use of microwave and millimeter wave nondestructive testing methods utilizing open ended rectangular waveguide sensors has shown great potential for detecting minute thickness variations in laminate structures, in particular those backed by a conducting plate. Slight variations in the dielectric properties of materials may also be detected using a set of optimal parameters which include the standoff distance and the frequency of operation. In a recent investigation, on detecting rust under paint, the dielectric properties of rust were assumed to be similar to those of Fe{sub 2}O{sub 3} powder. These values were used in an electromagnetic model that simulates the interaction of fields radiated by a rectangular waveguide aperture with layered structures to obtain optimal parameters. The dielectric properties of Fe{sub 2}O{sub 3} were measured to be very similar to the properties of paint. Nevertheless, the presence of a simulated Fe{sub 2}O{sub 3} layer under a paint layer was detected. In this paper the dielectric properties of several different rust samples from different environments are measured. The measurements indicate that the nature of real rust is quite diverse and is different from Fe{sub 2}O{sub 3} and paint, indicating that the presence of rust under paint can be easily detected. The same electromagnetic model is also used (with the newly measured dielectric properties of real rust) to obtain an optimal standoff distance at a frequency of 24 GHz. The results indicate that variations in the magnitude as well as the phase of the reflection coefficient can be used to obtain information about the presence of rust. An experimental investigation on detecting the presence of very thin rust layers (2.5--5 x 10{sup {minus}2} mm [09--2.0 x 10{sup {minus}3} in.]) using an open ended rectangular waveguide probe is also conducted. Microwave images of rusted specimens, obtained at 24 GHz, are also presented.

    The detection of freeze/thaw (F/T) physical state of soil is one of the main objectives of the SMAP mission as well as one of the secondary objectives of the SMOS mission. Annual F/T cycles have substantial impacts on surface energy budgets, permafrost conditions, as well as forest water and carbon dynamics. It has been shown that spaceborne L-band passive radiometry is a promising tool to monitor F/T due to the substantial differences between the permittivity of water and ice at these frequencies. However, the decoupling of the signal between soil and vegetation components remains challenging for all microwave remote sensing applications at various spatial scales. Radiative transfer models in the microwave domain are generally poorly parameterized to consider the non-negligible contribution of vegetation. The main objective of this research is to assess the skill of a recently developed Open-Ended Coaxial Probe (OECP) to measure the complex microwave permittivity of vegetation and soils and to derive a relation between the impact of vegetation on the microwave signal and the vegetation permittivity that could serve as a validation tool for soil models especially in frozen state. Results show that the OECP is a suitable tool to infer the radial profile of the complex permittivity in L-band of trees. A clear distinction can be made between the dielectric characterization of the sapwood where the permittivity is high because of the high permittivity of water but decrease with depth, and the heartwood where the permittivity is low and relatively constant. The seasonal cycle of the F/T state of the vegetation can also be observed since it is strongly correlated with the permittivity of the wood. The permittivity of a tree over the winter season is very low and homogenous since the permittivity of ice is significantly lower than water and the sap flow is negligible. The fluctuation of the frozen and thawed permittivity for different tree species was evaluated, focusing

    Open-ended products that allow an HMO enrollee to use providers who are not affiliated with the HMO have become an important component of the Clinton administration's health reform proposal, because these products maintain consumer freedom of choice of any provider. However, little is known about the consequences of offering an open-ended product from an organizational standpoint. This paper uses a theory of "spatial competition" to examine the decisions of health maintenance organizations to offer an open-ended product and the effect of offering an open-ended product on their enrollment.

    1977-01-01

    Radiation pattern of open ended waveguide excited in circular symmetric mode (TM 01 ) in an air core having central conductor and surrounded by an annular plasma column is studied. The field distribution at the open end of the waveguide is considered to be equivalent to the vector sum of magnetic current rings of various radii, ranging from the outer radius of the inner conductor to the inner radius of the outer conductor of the waveguide at the open end. The radiation field is obtained as a vector sum of field components due to individual rings of current. Such a configuration gives rise to multiple narrow radiation beams away from the critical angle. (author)

    Percutaneous sclerotherapy of the internal spermatic vein through an open ended guide wire was performed in 50 patients with left sided variocele. The procedure was successful in 47 patients, without major complications. Percutaneous sclerotherapy through an open ended guide wire offers the advantage of very distal and superselective catheterization with complete embolization of the internal spermatic vein, its side branches and parallel collateral channels. Further follow-up hopefully will confirm the reduction of recurrence rate in our patients.

  15. Clad vent set cup open end (closure weld zone) wall-thickness study

    Energy Technology Data Exchange (ETDEWEB)

    Ulrich, G.B.; Sherrill, M.W.

    1994-09-01

    The wall thickness at the open end of Clad Vent Set (CVS) cups is a very important parameter for maintaining control of the fueled CVS closure weld process. Ideally, the wall thickness in the closure weld zone should be constant. The DOP-26 iridium alloy is very difficult to machine; therefore, key dimensional features are established during the two-draw warm-forming operation. Unfortunately, anisotropy in the forming blanks produces four ears at the open end of each cup. Formation of these ears produces axial and circumferential variations in wall thickness. The cup certification requirement is that the wall thickness in the closure weld zone, defined as the 2.5-mm band at the open end of a cup, measure from 0.63 to 0.73 mm. The wall thickness certification data for the open end of the CVS cups have been statistically evaluated. These data show that the cups recently produced for the Cassini mission have well-controlled open-end wall thicknesses.

    2017-01-01

    Crowdsourcing is the primary means to generate training data at scale, and when combined with sophisticated machine learning algorithms, crowdsourcing is an enabler for a variety of emergent automated applications impacting all spheres of our lives. This paper surveys the emerging field of formally reasoning about and optimizing open-ended crowdsourcing, a popular and crucially important, but severely understudied class of crowdsourcing—the next frontier in crowdsourced data management. The underlying challenges include distilling the right answer when none of the workers agree with each other, teasing apart the various perspectives adopted by workers when answering tasks, and effectively selecting between the many open-ended operators appropriate for a problem. We describe the approaches that we’ve found to be effective for open-ended crowdsourcing, drawing from our experiences in this space. PMID:28951893

    Full Text Available Teaching and learning is fundamentally a two-way affair the teacher transferring knowledge and the learner making meaning from the knowledge. Teaching becomes complete when the learner acquires the knowledge transferred and applies it appropriately to real life situations. However in Ghana teaching and learning has undergone a lot of alteration coupled with both negative and positive effects. In Wa Polytechnic teaching and learning has seen little or no improvement with regards to information and communication Technology ICT making it difficult for students to acquire 21st century skills and be part of the digitally connected ecosystem. Active classroom participation and engagement information sharing communication collaboration coupled with large class sizes have been a problem for teachers and students in Wa Polytechnic hence the need to conduct a study to identify productive solutions that enhance students participation and engagement in the classroom. The study investigates the role of ICT in augmenting active participation and engagement of students in the classroom via open-ended response systems. The study was conducted using Educational Design Research EDR methods. A critical analysis was done by studying the responses of the respondents which identified three forms of students classroom participation and engagement verbal classroom participation non-verbal classroom participation and after classroom teaching and learning activities. Smart phones laptop tablet iPad and regular cellular phone were the predominant devices used by students for other purpose rather than teacher-led class activities. When students were made to actively participate in the classroom using the devices as open-ended response system students engagement and their ability to contribute during lectures appreciated comparatively. It was however evident that open-ended response system was effective tool to manage large class sizes as students who were timid could

    Full Text Available Near the end of a web survey respondents are often asked whether they have further comments. Such final comments are usually ignored, in part because open-ended questions are challenging to analyse. We explored whether final comments are associated with next-wave attrition in survey panels. We categorized a random sample of final comments in the Longitudinal Studies for the Social Sciences (LISS panel and Dutch Immigrant panel into one of eight categories (neutral, positive, six subcategories of negative and regressed the indicator of next-wave attrition on comment length, comment category and socio-demographic variables. In the Immigrant panel we found shorter final comments (55 words with decreased next-wave attrition relative to making no comment. Comments about unclear survey questions quadruple the odds of attrition and “other” (uncategorized negative comments almost double the odds of attrition. In the LISS panel, making a comment (vs. not and comment length are not associated with attrition. However, when specifying individual comment categories, neutral comments are associated with half the odds of attrition relative to not making a comment.

    2017-09-01

    The use of computer software such as Cabri 3D for learning activities is very unlimited. Students can adjust their learning speed according to their level of ability. Open-ended approach strongly supports the use of computer software in learning, because the goal of open-ended learning is to help developing creative activities and mathematical mindset of students through problem solving simultaneously. In other words, creative activities and mathematical mindset of students should be developed as much as possible in accordance with the ability of spatial ability of each student. Spatial ability is the ability of students in constructing and representing geometry models. This study aims to determine the improvement of spatial ability of junior high school students who obtained learning with open-ended approach aided by Cabri 3D. It adopted a quasi-experimental method with the non-randomized control group pretest-posttest design and the 2×3 factorial model. The instrument of the study is spatial ability test. Based on analysis of the data, it is found that the improvement of spatial ability of students who received open-ended learning aided by Cabri 3D was greater than students who received expository learning, both as a whole and based on the categories of students’ initial mathematical ability.

    Full Text Available In “Why Libertarians Should Reject Positive Rights,” Joshua Katz offers a critical response to the argument developed by Nicolás Maloberti in “Libertarianism and the Possibility of the Legitimate State.” In this rejoinder, Maloberti argues that Katz’s response fails on two accounts. First, it fails to grasp the nature of the problem his article was ultimately concerned with. Second, it fails to present a solid case for the rejection of the type of positive right that it was argued libertarians should endorse as a solution to that problem.

  16. Transparency in Transcribing: Making Visible Theoretical Bases Impacting Knowledge Construction from Open-Ended Interview Records

    Directory of Open Access Journals (Sweden)

    Audra Skukauskaite

    2012-01-01

    Full Text Available This article presents a reflexive analysis of two transcripts of an open-ended interview and argues for transparency in transcribing processes and outcomes. By analyzing ways in which a researcher's theories become consequential in producing and using transcripts of an open-ended interview, this paper makes visible the importance of examining and presenting theoretical bases of transcribing decisions. While scholars across disciplines have argued that transcribing is a theoretically laden process (GREEN, FRANQUIZ & DIXON, 1997; KVALE & BRINKMAN, 2009, few have engaged in reflexive analyses of the data history to demonstrate the consequences particular theoretical and methodological approaches pose in producing knowledge claims and inciting dialogues across traditions. The article demonstrates how theory-method-claim relationships in transcribing influence research transparency and warrantability. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1201146

  17. The Solving of Problems in Chemistry: the more open-ended problems

    2002-01-01

    Most problem solving in chemistry tends to be algorithmic in nature, while problems in life tend to be very open ended. This paper offers a simple classification of problems and seeks to explore the many factors which may be important in the successful solving of problems. It considers the place of procedures and algorithms. It analyses the role of long-term memory, not only in terms of what is known, but how that knowledge was acquired. It notes the great importance of the limitations of working memory space and the importance of confidence which comes from experience. Finally, various psychological factors are discussed. This paper argues that solving open-ended problems is extremely important in education and that offering learners experience of this in a group work context is a helpful way forward.

    2012-01-01

    Full Text Available The purpose of this study was to identify and examine the themes in the written productions of 114 kindergarten students. Participants were from two schools in different regions in the United States and were given an open-ended opportunity to draw and subsequently dictate a story. Content analysis was performed and six themes emerged: (a family, (b inanimate objects/personal belongings, (c activities/events, (d fantasy stories, (e self-talk/reflection, and (f nature/outdoors. Comparative analysis was performed for both gender and ethnicity and few differences were found between boys’ and girls’ stories or across ethnicities. Recommendations were included for teachers and families to allow young children more open-ended literacy opportunities and future research to analyze children’s drawings and stories between classrooms and across grade levels were included.

    Full Text Available Most studies of volunteers’ motivations use standardized questionnaires with one of the most commonly-used being the Volunteer Function Inventory. Open-ended questions about what drives individuals to be volunteers are seldom used. We hypothesize that questionnaires tend to overestimate the number of motivations and to underestimate their variety. Therefore, in this paper we analyze the answers of 1515 volunteers to an open-ended question and categorize these answers. Results show that volunteers give an average of 2 motivations, fewer than the questionnaires, and that the Value motivation is the most frequently mentioned and the most important for volunteers. In addition, this motivation coexists with other motivations, which are lacking in the standard questionnaires, such as Organizational Commitment, Personal Development, Religiosity, Social Change or Interest in the Activity.

  20. Ambiguity towards Multiple Historical Performance Information Signals: Evidence from Indonesian Open-Ended Mutual Fund Investors

    2015-10-01

    Full Text Available This study focuses on the behavior of open-ended mutual fund investors when encountered with multiple information signals of mutual fund’s historical performance. The behavior of investors can be reflected on their decision to subscribe or redeem their funds from mutual funds. Moreover, we observe the presence of ambiguity within investors due to multiple information signals, and also their reaction towards it. Our finding shows that open-ended mutual fund investors do not only have sensitivity towards past performance information signals, but also have additional sensitivity towards the ambiguity of multiple information signals. Because of the presence of ambiguity, investors give more consideration to negative information signals and the worst information signal in their investment decisions.

    2015-01-01

    This study aims to examine whether funds with illiquid assets exhibit stronger sensitivity of redemption outflows to bad past performance than funds with liquid assets. An important aspect of our study is whether large outflows should damage future fund performance in illiquid funds more than in liquid funds. When redeemed in a large scale, the liquidity risk of open-end funds will increase, which in turn leads to a vicious circle between fund redemption and the net asset value decline. Accor...

    Miller, Rachel; Mason, Susan E

    2012-01-01

    The concept of open-ended groups is expanded to include an open-door model (OEOD) wherein members with severe mental illnesses, including schizophrenia disorders and bi-polar, can join, leave, and re-enter groups as their life circumstances dictate their availability and willingness for treatment. This model is grounded on the work of Schopler and Galinsky's (1984/2006) and Galinsky and Schopler's (1989) theses on the value and processes of open-ended groups and includes perspectives on mutual aid and group development. Groupwork with the OEOD format is illustrated with examples taken from a group of 79 participants diagnosed with first-episode schizophrenia/schizoaffective disorders, 40 of who had co-occurring substance abuse. Of the 79 participants in the OEOD group program, 70 (89%) remained in treatment for the maximum of 3 years. The over-all value of group treatment for this population is reviewed along with the small number of available publications on open-ended and open-door-type groups.

    This study aims to find out students metacognition difficulty during solving open-ended problem in mathematics. It focuses on analysing the metacognition difficulty of students with visual-spatial intelligence in solving open-ended problem. A qualitative research with case study strategy is used in this study. Data in the form of visual-spatial intelligence test result and recorded interview during solving open-ended problems were analysed qualitatively. The results show that: (1) students with high visual-spatial intelligence have no difficulty on each metacognition aspects, (2) students with medium visual-spatial intelligence have difficulty on knowledge aspect on strategy and cognitive tasks, (3) students with low visual-spatial intelligence have difficulty on three metacognition aspects, namely knowledge on strategy, cognitive tasks and self-knowledge. Even though, several researches about metacognition process and metacognition literature recommended the steps to know the characteristics. It is still important to discuss that the difficulties of metacognitive is happened because of several factors, one of which on the characteristics of student’ visual-spatial intelligence. Therefore, it is really important for mathematics educators to consider and pay more attention toward students’ visual-spatial intelligence and metacognition difficulty in designing better mathematics learning.

  6. Open-ended versus guided laboratory activities:Impact on students' beliefs about experimental physics

    Wilcox, Bethany R.; Lewandowski, H. J.

    2016-12-01

    Improving students' understanding of the nature of experimental physics is often an explicit or implicit goal of undergraduate laboratory physics courses. However, lab activities in traditional lab courses are typically characterized by highly structured, guided labs that often do not require or encourage students to engage authentically in the process of experimental physics. Alternatively, open-ended laboratory activities can provide a more authentic learning environment by, for example, allowing students to exercise greater autonomy in what and how physical phenomena are investigated. Engaging in authentic practices may be a critical part of improving students' beliefs around the nature of experimental physics. Here, we investigate the impact of open-ended activities in undergraduate lab courses on students' epistemologies and expectations about the nature of experimental physics, as well as their confidence and affect, as measured by the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS). Using a national data set of student responses to the E-CLASS, we find that the inclusion of some open-ended lab activities in a lab course correlates with more expertlike postinstruction responses relative to courses that include only traditional guided lab activities. This finding holds when examining postinstruction E-CLASS scores while controlling for the variance associated with preinstruction scores, course level, student major, and student gender.

  7. Determining the Response Behaviors of Middle School Students for Open-Ended Questions

    2017-04-01

    Full Text Available When the literature for measurement and evaluation in education is reviewed, research related to student achievement are mainly outcome-oriented rather than process-oriented. Researchers pay attention to the responses that a student constructs or chooses, and ignore the cognitive processes that forces students to construct or choose that specific response. Recognizing the cognitive processes a student uses in responding to a question affects the item construction process and psychometric audit on items. Response behavior is a result of a cognitive process used to respond to a question and is accepted as an indicator of student cognitive competence. This study aims to determine the students’ response behaviors for open-ended questions. The study group consisted of 70 students from the 5th grade studying during the 2015-2016 education year spring term in the Cankaya and Mamak districts of Ankara province, Turkey. An authentic achievement test which consisted of eight open-ended questions is used as the data collection tool. Students are asked to write in detail how they construct their response in their mind in the blank space set aside after each question. Data is analyzed via grouping students’ response behaviors and expert opinions. Research findings revealed that students perform 14 different response behaviors for open-ended questions. These behaviors are themed as responses constructed directly from the text, responses constructed by interpreting the text, and responses constructed by linking real life and the text.

  8. Undecidability and Irreducibility Conditions for Open-Ended Evolution and Emergence.

    2018-01-01

    Is undecidability a requirement for open-ended evolution (OEE)? Using methods derived from algorithmic complexity theory, we propose robust computational definitions of open-ended evolution and the adaptability of computable dynamical systems. Within this framework, we show that decidability imposes absolute limits on the stable growth of complexity in computable dynamical systems. Conversely, systems that exhibit (strong) open-ended evolution must be undecidable, establishing undecidability as a requirement for such systems. Complexity is assessed in terms of three measures: sophistication, coarse sophistication, and busy beaver logical depth. These three complexity measures assign low complexity values to random (incompressible) objects. As time grows, the stated complexity measures allow for the existence of complex states during the evolution of a computable dynamical system. We show, however, that finding these states involves undecidable computations. We conjecture that for similar complexity measures that assign low complexity values, decidability imposes comparable limits on the stable growth of complexity, and that such behavior is necessary for nontrivial evolutionary systems. We show that the undecidability of adapted states imposes novel and unpredictable behavior on the individuals or populations being modeled. Such behavior is irreducible. Finally, we offer an example of a system, first proposed by Chaitin, that exhibits strong OEE.

    Pop Izabela Luiza

    2017-01-01

    Full Text Available Despite the failures that investment funds have registered in Romania by the year 2000, they are a financial instrument chosen by more and more people to capitalize on their savings. Therefore, open-end investment funds have had a steady growth trend in Romania over the past 10 years; their net asset value increased by 24 times and the number of investors tripled. In this context, the purpose of our paper is to present possible factors that have caused this increase. Particularly, the empirical research focuses on studying the links that might exist between open-end investment funds, bank deposits and interest rates on bank deposits. The correlations between these variables were analysed by computing the Pearson's correlation coefficient. The results highlight a high negative relationship that exist between net asset value of investment funds and bank interest. Nevertheless, it has been found that bank deposits are related neither to the interest rate nor to the open-end investment funds.

    2014-07-01

    Full Text Available In this paper the problem of radiation from the open end of a semi-infinite circular metallic waveguide with perfectly conducting walls and a thin internal low-conducting metal coating is considered. Electromagnetic fields are generated by the ultrarelativistic point charge moving along the axis of the waveguide. The far fields of radiation are obtained using the near-field to far-field recovery technique. The technique is extended for the nonmonochromatic waves. It is shown that the radiation has a narrow-band and narrow-directional character.

    To evaluate the true necessity of open end ureteral catheter insertion in patients with moderate to severe pelvicalyceal system dilation treated with percutaneous nephrolithotomy (PNL) under sonographic guidance. 50 cases treated with PNL under sonographic guidance in prone position for solitary obstructing renal stones were evaluated. Patients were randomly divided into two groups; Group 1: Patients in whom a open end ureteral catheter was inserted prior to the procedure; Group 2: Patients receiving no catheter before PNL. In addition to the duration of the procedure as a whole and also all relevant stages as well, radiation exposure time, hospitalization period, mean nephrostomy tube duration, mean drop in Hb levels and all intra and postoperative complications have been evaluated. Mean size of the stones was 308.5 ± 133.2 mm2. Mean total duration of the PNL procedure in cases with open end ureteral catheter was significantly longer than the other cases (p < 0.001). Evaluation of the outcomes of the PNL procedures revealed no statistically significant difference between two groups regarding the stone-free rates (86% vs 84%). Additionally, there was no significant difference with respect to the duration of nephrostomy tube, hospitalization period and secondary procedures needed, complication rates as well as the post-operative Hb drop levels in both groups (p = 0.6830). Our results indicate that the placement of an open end ureteral catheter prior to a PNL procedure performed under sonographic access may not be indicated in selected cases presenting with solitary obstructing renal pelvic and/or calyceal stones.

    2018-01-01

    Critical thinking plays an important role for students in solving open-ended problems. This research aims at describing student’s critical thinking in solving open-ended problems based on Keirsey’s personality types, namely rational, idealist, guardian, and artisan. Four students, with the higher rank in the mathematics’ test and representing each type of Keirsey personality, were selected as the research subjects. The data were collected from the geometry problem and interviews. The student’s critical thinking is described based on the FRISCO criteria. The result underlines that rational and idealist students fulfilled all FRISCO criteria, and but not for guardian and artisan students. Related to the inference criteria, guardian and artisan students could not make reasonable conclusions and connect the concepts. Related to the reason of criteria, rational student performed critical thinking by providing logical reason that supported his strategy to solve the problem. In contrast, the idealist student provided subjective reason. This results suggest that teachers should frequently train the students’ logical thinkingin every lesson and activity to develop student’s critical thinking and take the student’s personality character into account, especially for guardian and artisan students.

  1. Temporal and Spatial Patterns of Neural Activity Associated with Information Selection in Open-ended Creativity.

    Novel information selection is a crucial process in creativity and was found to be associated with frontal-temporal functional connectivity in the right brain in closed-ended creativity. Since it has distinct cognitive processing from closed-ended creativity, the information selection in open-ended creativity might be underlain by different neural activity. To address this issue, a creative generation task of Chinese two-part allegorical sayings was adopted, and the trials were classified into novel and normal solutions according to participants' self-ratings. The results showed that (1) novel solutions induced a higher lower alpha power in the temporal area, which might be associated with the automatic, unconscious mental process of retrieving extensive semantic information, and (2) upper alpha power in both frontal and temporal areas and frontal-temporal alpha coherence were higher in novel solutions than in normal solutions, which might reflect the selective inhibition of semantic information. Furthermore, lower alpha power in the temporal area showed a reduction with time, while the frontal-temporal and temporal-temporal coherence in the upper alpha band appeared to increase from the early to the middle phase. These dynamic changes in neural activity might reflect the transformation from divergent thinking to convergent thinking in the creative progress. The advantage of the right brain in frontal-temporal connectivity was not found in the present work, which might result from the diversity of solutions in open-ended creativity.

  5. Effect of filling ratio on premixed methane/air explosion in an open-end pipe

    2016-06-01

    Full Text Available The propagation characteristics of premixed methane/air explosion under different filling ratios (20%, 30%, 40%, 50%, 60%, and 100% were studied using an experimental system. The results indicate that the peak overpressure showed a decreasing trend at the initial stage but then showed an increasing trend until reaching its maximum value under different filling ratios. As the explosion propagated to the open end, the overpressure showed a downtrend. At this point, the flame speed initially increased along the pipe but then dropped dramatically. In addition, the explosion overpressure and flame speed increased with the increase of filling ratio. However, when the filling ratio reached 50%, the explosion overpressure and flame speed tended to be stable and the increase was not obvious. These results will be of great importance in evaluating the explosive damage to equipment and human personnel working in coal mines or other chemical industries.

    Open-ended evolution (OEE) is relevant to a variety of biological, artificial and technological systems, but has been challenging to reproduce in silico. Most theoretical efforts focus on key aspects of open-ended evolution as it appears in biology. We recast the problem as a more general one in dynamical systems theory, providing simple criteria for open-ended evolution based on two hallmark features: unbounded evolution and innovation. We define unbounded evolution as patterns that are non-repeating within the expected Poincare recurrence time of an isolated system, and innovation as trajectories not observed in isolated systems. As a case study, we implement novel variants of cellular automata (CA) where the update rules are allowed to vary with time in three alternative ways. Each is capable of generating conditions for open-ended evolution, but vary in their ability to do so. We find that state-dependent dynamics, regarded as a hallmark of life, statistically out-performs other candidate mechanisms, and is the only mechanism to produce open-ended evolution in a scalable manner, essential to the notion of ongoing evolution. This analysis suggests a new framework for unifying mechanisms for generating OEE with features distinctive to life and its artifacts, with broad applicability to biological and artificial systems.

  7. The Cultural Evolution of Structured Languages in an Open-Ended, Continuous World.

    Carr, Jon W; Smith, Kenny; Cornish, Hannah; Kirby, Simon

    2017-05-01

    Language maps signals onto meanings through the use of two distinct types of structure. First, the space of meanings is discretized into categories that are shared by all users of the language. Second, the signals employed by the language are compositional: The meaning of the whole is a function of its parts and the way in which those parts are combined. In three iterated learning experiments using a vast, continuous, open-ended meaning space, we explore the conditions under which both structured categories and structured signals emerge ex nihilo. While previous experiments have been limited to either categorical structure in meanings or compositional structure in signals, these experiments demonstrate that when the meaning space lacks clear preexisting boundaries, more subtle morphological structure that lacks straightforward compositionality-as found in natural languages-may evolve as a solution to joint pressures from learning and communication.

    We present the theory and implementation of an open-ended framework for electric response properties at the level of Hartree-Fock and Kohn-Sham density functional theory that includes effects from the molecular environment modeled by the polarizable embedding (PE) model. With this new state-of-the-art multiscale functionality, electric response properties to any order can be calculated for molecules embedded in polarizable atomistic molecular environments ranging from solvents to complex heterogeneous macromolecules such as proteins. In addition, environmental effects on multiphoton absorption (MPA) properties can be studied by evaluating single residues of the response functions. The PE approach includes mutual polarization effects between the quantum and classical parts of the system through induced dipoles that are determined self-consistently with respect to the electronic density. The applicability of our approach is demonstrated by calculating MPA strengths up to four-photon absorption for the green fluorescent protein. We show how the size of the quantum region, as well as the treatment of the border between the quantum and classical regions, is crucial in order to obtain reliable MPA predictions.

    The patient is a 27-year-old previously healthy male with a diagnosis of viral encephalitis with a lymphocytic pleocytosis on cerebrospinal fluid examination. For 3 months, he has been in status epilepticus (SE) on high doses of barbiturates, benzodiazepines, and ketamine and a ketogenic feeding-tube formula. He remains in burst suppression on continuous electroencephalography (EEG). He is trached and has a percutaneous endoscopic gastrostomy (PEG) feeding tube. He has been treated several times for pneumonia, and he is on a warming blanket and is on vasopressors to maintain his blood pressure. His vitals are stable and his lab work is within limits. The sedation is decreased under EEG guidance every 72 hours, after which he goes back into SE and heavy sedation is resumed. The latest magnetic resonance imaging (MRI) shows edema but otherwise no obvious permanent cortical damage. The family wants a realistic assessment of the likely outcome. The neurologist tells them the literature suggests the outlook is poor but not 100% fatal. As long as all of his other organs are functioning on life support, there is always a chance the seizures will stop at some time in the future, and so the neurologist recommends an open-ended intensive care unit (ICU) plan and hopes for that outcome.

  10. Open-Ended Measurement of Whole-Body Movement: A Feasibility Study

    Finn, Michael T. M.

    2018-02-01

    Full Text Available As the importance of embodiment emerges for psychology, there is a need to advance methodology for measuring the dynamics of movement in an open-ended fashion. Such a tool should be versatile across contexts and track spontaneous and natural movement with minimal constraints. We test the feasibility of a method for measuring whole-body movement over time that attempts to meet this need. We use a motion capture system comprised of two Microsoft Kinect version 2.0 cameras and iPiSoft Motion Capture software, and compare its estimates of magnitude rotational velocity and whole-body movement complexity (multivariate multiscale sample entropy; MMSE to that of a gold standard motion capture system across a variety of movement sequences. The candidate system satisfactorily estimated the instantaneous velocity of 13 body segments in agreement with the gold standard system across movement sequences demonstrating initial feasibility of this process. Summary calculations of velocity by sequence and MMSE calculations were also in high agreement with the gold standard, crucially suggesting that the candidate system could pick up on the complex dynamics of movement over time. The candidate system was feasible and demonstrates preliminary validity for general use in the tracking of continuous human movement for clinical and experimental psychology. We also provide R code and sample data for the importing and processing of movement data exported from iPiSoft Motion Capture Studio.

    The vortex ring generated subsequent to the diffraction of a shock wave from the open end of a shock tube is studied using particle image velocimetry. We examine the early evolution of the compressible vortex ring for three-exit shock Mach numbers, 1.1, 1.2, and 1.3. For the three cases studied, the ring formation is complete at about tUb/D=2, where t is time, Ub is fluid velocity behind shock as it exits the tube and D is tube diameter. Unlike in the case of piston generated incompressible vortex rings where the piston velocity variation with time is usually trapezoidal, in the shock-generated vortex ring case the exit fluid velocity doubles from its initial value Ub before it slowly decays to zero. At the end of the ring formation, its translation speed is observed to be about 0.7 Ub. During initial formation and propagation, a jet-like flow exists behind the vortex ring. The vortex ring detachment from the tailing jet, commonly referred to as pinch-off, is briefly discussed.

  12. Experimental study on pressure wave propagation through the open end of pipe

    The steam generators of a double pool type liquid metal fast breeder reactor (LMFBR) are used in a large sodium pool which is formed between the primary vessel and the secondary vessel and accommodates the entire secondary heat transport system. Therefore, if there is a sodium-water reaction event in the steam generator, it becomes important to evaluate the pressure rises at the walls of the primary and secondary vessels as well as those at the other secondary components. An experimental study was performed, focusing on the propagation of the initial pressure spike of the-sodium-water reaction from the bottom end of the steam generator to the sodium pool. Pressure wave propagation from inside of a pipe to an open space through the pipe end was measured. Two kinds of pressure propagation media, water and air, ensured a wide range of experimental conditions. The experimental results revealed that the pressure attenuation at the open end of a pipe can be put in order using the concept of inertial length, and that the dimensionless inertial length, i.e., the inertial length divided by the half wave length of the pressure pulse, is proportional to the square of the dimensionless diameter. These results provide a prediction method for a pressure rise by the initial pressure spike in the secondary sodium pool of the Double Pool LMFBR

  13. Authentic Learning Enviroment in Analytical Chemistry Using Cooperative Methods and Open-Ended Laboratories in Large Lecture Courses

    Wright, John C.

    1996-09-01

    It is recognized that a need exists to move from the passive learning styles that have characterized chemistry courses to an active style in which students participate and assume responsibility for their learning (1 - 5). In addition, it is argued that course reform should be linked to authentic student achievement, so that students can actively experience the feelings of practicing professionals (6). Course experiments where such changes have been introduced have proven successful but the number of examples of such changes is limited in the higher level courses or courses with large enrollments (7 - 11). In this paper, a one-semester introductory analytical chemistry course is described that accomplishes this goal by the use of open-ended laboratories, cooperative learning, and spreadsheet programs. The course uses many of the ideas described by Walters (7). It is offered at the upperclass level to nonmajors and at the freshman level to students with solid chemistry backgrounds from high school. Typically there are 90 students, who are divided into 5 sections. A teaching assistant is assigned to each section. The course has two 4-hour laboratories and two or three lectures each week (depending on whether it is the upperclass or freshman course). The heart of the course changes is the use of open-ended laboratory experiments in the last half of the course. A sample group project is to have the students develop a mixture of acid-base indicators that can serve as a spectroscopic pH meter. These projects are enhanced by dividing the students into teams of four who take charge of all aspects of accomplishing the projects' goals. Since there are many skills required to make these projects work, the first half of the course is spent developing the individual conceptual, computational, laboratory, problem solving, and group skills so students are prepared for the last half. These changes have markedly improved the student attitudes towards each other and towards learning

  17. Using Negotiated Joining to Construct and Fill Open-ended Roles in Elite Culinary Groups.

    Science.gov (United States)

    Tan, Vaughn

    2015-03-01

    This qualitative study examines membership processes in groups operating in an uncertain environment that prevents them from fully predefining new members' roles. I describe how nine elite high-end, cutting-edge culinary groups in the U.S. and Europe, ranging from innovative restaurants to culinary R&D groups, use negotiated joining-a previously undocumented process-to systematically construct and fill these emergent, open-ended roles. I show that negotiated joining is a consistently patterned, iterative process that begins with a role that both aspirant and target group explicitly understand to be provisional. This provisional role is then jointly modified and constructed by the aspirant and target group through repeated iterations of proposition, validation through trial and evaluation, and selective integration of validated role components. The initially provisional role stabilizes and the aspirant achieves membership if enough role components are validated; otherwise the negotiated joining process is abandoned. Negotiated joining allows the aspirant and target group to learn if a mutually desirable role is likely and, if so, to construct such a role. In addition, the provisional roles in negotiated joining can support absorptive capacity by allowing novel role components to enter target groups through aspirants' efforts to construct stable roles for themselves, while the internal adjustment involved in integrating newly validated role components can have the unintended side effect of supporting adaptation by providing opportunities for the groups to use these novel role components to modify their role structure and goals to suit a changing and uncertain environment. Negotiated joining thus reveals role ambiguity's hitherto unexamined beneficial consequences and provides a foundation for a contingency theory of new-member acquisition.

    Karl W. Kosko

    2011-07-01

    Full Text Available Quantitative Literacy (QL has been described as the skill set an individual uses when interacting with the world in a quantitative manner. A necessary component of this interaction is communication. To this end, assessments of QL have included open-ended items as a means of including communicative aspects of QL. The present study sought to examine whether such open-ended items typically measured aspects of quantitative communication, as compared to mathematical communication, or mathematical skills. We focused on public-released items and rubrics from four of the most widely referenced assessments: the Third International Mathematics and Science Study (TIMSS-95: the National Adult Literacy Survey (NALS; now the National Assessment of Adult Literacy, NAAL in 1985 and 1992, the International Adult Literacy Skills (IALS beginning in 1994; and the Program for International Student Assessment (PISA beginning in 2000. We found that open-ended item rubrics in these QL assessments showed a strong tendency to assess answer-only responses. Therefore, while some open-ended items may have required certain levels of quantitative reasoning to find a solution, it is the solution rather than the reasoning that was often assessed.

    The sequence used for collecting quantitative and qualitative data in concurrent mixed-methods research may influence participants' responses. Empirical evidence is needed to determine if the order of data collection in concurrent mixed methods research biases participants' responses to closed and open-ended questions. To examine the influence of the quantitative-qualitative sequence on responses to closed and open-ended questions when assessing the same variables or aspects of a phenomenon simultaneously within the same study phase. A descriptive cross-sectional, concurrent mixed-methods design was used to collect quantitative (survey) and qualitative (interview) data. The setting was a large multi-site health care centre in Canada. A convenience sample of 50 registered nurses was selected and participated in the study. Participants were randomly assigned to one of two sequences for data collection, quantitative-qualitative or qualitative-quantitative. Independent t-tests were performed to compare the two groups' responses to the survey items. Directed content analysis was used to compare the participants' responses to the interview questions. The sequence of data collection did not greatly affect the participants' responses to the closed-ended questions (survey items) or the open-ended questions (interview questions). The sequencing of data collection, when using both survey and semi-structured interviews, may not bias participants' responses to closed or open-ended questions. Additional research is required to confirm these findings. Copyright © 2011 Elsevier Ltd. All rights reserved.

  9. Should essays and other "open-ended"-type questions retain a place in written summative assessment in clinical medicine?

    Science.gov (United States)

    Hift, Richard J

    2014-11-28

    Written assessments fall into two classes: constructed-response or open-ended questions, such as the essay and a number of variants of the short-answer question, and selected-response or closed-ended questions; typically in the form of multiple-choice. It is widely believed that constructed response written questions test higher order cognitive processes in a manner that multiple-choice questions cannot, and consequently have higher validity. An extensive review of the literature suggests that in summative assessment neither premise is evidence-based. Well-structured open-ended and multiple-choice questions appear equivalent in their ability to assess higher cognitive functions, and performance in multiple-choice assessments may correlate more highly than the open-ended format with competence demonstrated in clinical practice following graduation. Studies of construct validity suggest that both formats measure essentially the same dimension, at least in mathematics, the physical sciences, biology and medicine. The persistence of the open-ended format in summative assessment may be due to the intuitive appeal of the belief that synthesising an answer to an open-ended question must be both more cognitively taxing and similar to actual experience than is selecting a correct response. I suggest that cognitive-constructivist learning theory would predict that a well-constructed context-rich multiple-choice item represents a complex problem-solving exercise which activates a sequence of cognitive processes which closely parallel those required in clinical practice, hence explaining the high validity of the multiple-choice format. The evidence does not support the proposition that the open-ended assessment format is superior to the multiple-choice format, at least in exit-level summative assessment, in terms of either its ability to test higher-order cognitive functioning or its validity. This is explicable using a theory of mental models, which might predict that the

    2005-01-01

    Socioemotional selectivity theory (SST; Carstensen, 1995, Current Directions in Psychological Science, 4, 151-156) predicts that novel social partners are preferred in open-ended situations, whereas familiar social partners are preferred in future-limited situations. The authors attempted to generalize past research to new familiar and novel partner options. Studies 1 (N=144; undergraduates, community-dwelling adults ages 65 to 95) and 2 (N=336 community-dwelling participants ages 11 to 89) indicated that young and older participants in a future-limited situation preferred familiar partners. However, with different social partner options than have been used in previous research, young participants in an open-ended situation also preferred a familiar partner, contrary to the predictions of SST.

    2018-01-01

    Full Text Available In this paper, a planar printed hybrid short/open-ended slot antenna with capacitive coupling feed strips is proposed for hepta-band mobile applications. The proposed antenna is comprised of a slotted ground plane on the top plane and two capacitive coupling feed strips with a chip inductor on the bottom plane. At the low frequency band, the short-ended long slot fed by strip 1 generates its half-wavelength resonance mode, whereas the T-shaped open ended slot fed by strip 2 generates its quarter-wavelength resonance mode for the high frequency band. The antenna provides a wide bandwidth covering GSM850/GSM900/DCS/PCS/UMTS/LTE2300/LTE2500 operation bands. Moreover, the antenna occupies a small volume of 15 mm × 50 mm × 1 mm. The operating principle of the proposed antenna and the simulation/measurement results are presented and discussed.

During the panic only strategic complementarities drive withdrawals. Furtherm...

  16. A Possible Link between Supra-Second Open-Ended Timing Sensitivity and Obsessive-Compulsive Tendencies.

    2016-01-01

    One of the main characteristics of obsessive-compulsive disorder (OCD) is the persistent feeling of uncertainty, affecting many domains of actions and feelings. It was recently hypothesized that OCD uncertainty is related to attenuated access to internal states. As supra-second timing is associated with bodily and interoceptive awareness, we examined whether supra-second timing would be associated with OC tendencies. We measured supra-second (~9 s) and sub-second (~450 ms) timing along with control non-temporal perceptual tasks in a group of 60 university students. Supra-second timing was measured either with fixed criterion tasks requiring to temporally discriminate between two predefined fixed interval durations (9 vs. 9.9 s), or with an open-ended task requiring to discriminate between 9 s and longer intervals which were of varying durations that were not a priori known to the participants. The open-ended task employed an adaptive Bayesian procedure that efficiently estimated the duration difference required to discriminate 9 s from longer intervals. We also assessed symptoms of OCD, depression, and anxiety. Open-ended supra-second temporal sensitivity was correlated with OC tendencies, as predicted (even after controlling for depression and anxiety), whereas the other tasks were not. Higher OC tendencies were associated with lower timing sensitivity to 9 s intervals such that participants with higher OC tendency scores required longer interval differences to discriminate 9 s from longer intervals. While these results need to be substantiated in future research, they suggest that open-ended timing tasks, as those encountered in real-life (e.g., estimating how long it would take to complete a task), might be adversely affected in OCD.

    Graphical abstract: Thinned, open-ended, and defected carbon nanotubes were prepared by using hydrogen plasma processing. The processed carbon nanotubes have far better field emission performance than that of the pristine ones. - Highlights: • CVD prepared CNT arrays were processed by microwave hydrogen plasma. • Thinned, open-ended, and defected CNTs were obtained. • Processed CNTs have far better field emission performance than the pristine ones. • Processed CNTs have applicable emission stability after being perfectly aged. - Abstract: Ultralow field emission is achieved from carbon nanotubes (CNTs) by using microwave hydrogen plasma processing. After the processing, typical capped CNT tips are removed, with thinned, open-ended, and defected CNTs left. Structural analyses indicate that the processed CNTs have more SP{sup 3}-hybridized defects as compared to the pristine ones. The morphology of CNTs can be readily controlled by adjusting microwave powers, which change the shape of CNTs by means of hydrogen plasma etching. Processed CNTs with optimal morphology are found to have an ultralow turn-on field of 0.566 V/μm and threshold field of 0.896 V/μm, much better than 0.948 and 1.559 V/μm of the as-grown CNTs, respectively. This improved FE performance is ascribed to the structural changes of CNTs after the processing. The thinned and open-ended shape of CNTs can facilitate electron tunneling through barriers and additionally, the increased defects at tube walls can serve as new active emission sites. Furthermore, our plasma processed CNTs exhibit excellent field emission stability at a large emission current density of 10.36 mA/cm{sup 2} after being perfectly aged, showing promising prospects in applications as high-performance vacuum electron sources.

    Creativity is often seen as one of the fundamental aspects of character education. As one of the 21st century skills, creativity has also been considered as an important goal of education across the world. This paper reports a study on promoting mathematical creativity through the use of open-ended mathematics problems. A total of 53 undergraduate students participated in the study. These students worked on open-ended problems in two types, i.e. bare mathematics problem and contextual problem. The contextual problem was presented in the form of paper-based and Geogebra-based. The students’ works were analysed qualitatively in order to describe how students’ mathematical creativity developed. It was found that the open-ended problems successfully promote students’ creativity as indicated by various solutions or strategies that were used by students to solve the problems. The analysis of students’ works show that students’ creativity developed through three kinds of exploration, i. e. (1) exploration of contexts, (2) exploration of software features, and (3) exploration of mathematics concepts. The use of metacognitive questioning was found to be helpful to develop the first two explorations into mathematical exploration.

    schools and colleges are exploring electronic learning through the internet and virtual labs (see Steve Mellema's use of IT in his Lecture for the 21st Century). We aim to provide useful material for everybody at and in between the extremes. But some words of caution, sounded by Robertson in Stirling: today we might find that our classes are motivated and interested when we use computers, but how long will the excitement last? If every lesson faces children with computer screens will they soon get bored and demotivated? Individual learning, through worksheets, was a great success when it was developed in the 70s, but when every lesson faced a child with yet another worksheet, students were turned off. It became known as 'death by a thousand worksheets'. Let's not abuse computers in the same way. Physics for the beach and the igloo Physics is about being cool, as we are always trying to tell our students! In this 'summer' issue we have two papers which allow us to demonstrate this practically. I should also like to remind readers that Physics Education is available online (www.iop.org/Journals/pe) in addition to the paper version. The electronic version has the advantages of hotlinks to websites, search facilities and the ability to download teaching materials. My guess is that we haven't begun to explore the possibilities of the electronic journal as a teaching resource for teachers. If it can be stored electronically, we can include it as a multimedia clip pictures, worksheets, spreadsheets, videos, sounds... But there are also many advantages of paper—convenience and permanence being just two. Physics Education is a worthwhile publication and it feels like that in your hand. Having a journal like this, to put in my bag, or stack on my bookshelf, still feels good to me. And judging by readers' comments, you agree. IOPP will, no doubt, support both formats for a long time to come. So, this summer, enjoy the format you are reading, read Physics Education on screen or on

    2015-11-01

    Recently, there has been a trend towards adding a multidisciplinary or multicultural element to traditional monodisciplinary project courses in computing and engineering. In this article, we examine the implications of multidisciplinarity for students' learning experiences during a one-semester project course for real customers. We use a qualitative research approach and base our analysis on students' learning reports on three instances of a project course titled Multidisciplinary working life project. The main contribution of this article is the unified theoretical picture of the learning mechanisms stemming from multidisciplinarity. Our main conclusions are that (1) students generally have a positive view of multidisciplinarity; (2) multidisciplinary teams enable students to better identify their own expertise, which leads to increased occupational identity; and (3) learning experiences are not fixed, as team spirit and student attitude play an important role in how students react to challenging situations arising from introduction of the multidisciplinarity.

    Full Text Available A triple-band rectangular ring, open-ended monopole antenna with symmetric L strips for wireless local area network (WLAN/Worldwide Interoperability of Microwave Access (WiMAX applications is proposed. The proposed antenna consists of two symmetric folded arms and L strips. Based on the concept, a prototype of the proposed triple antenna has been designed, fabricated, and tested. The numerical and experimental results demonstrated that the proposed antenna satisfied the −10 dB impedance bandwidth requirement while simultaneously covering the WLAN and WiMAX bands. Furthermore, this paper presented and discussed the 2D radiation patterns and 3D gains according to the results of the experiment. The proposed antenna’s peak gain varied between 2.17 and 4.93 dBi, and its average gain varied between −2.97 and −0.53 dBi.

  12. Experimental Investigation of Damage and Fracture Mechanisms Controlling the Performance of Full Aperture Easy Open Ends for Food Containers

    2011-05-01

    Can manufacturers produce hundreds of millions of cans annually, increasingly, food cans are being opened by lifting a tab on the can end that initiates a fracture, which then propagates around a circumferential score. The damage and fracture mechanisms that lead to crack initiation and propagation in the opening process, however, are not fully understood, therefore optimisation of easy open end scores is largely based on trial and error. This paper presents an experimental analysis that concentrates on the combined shear and bending forces as applied to the particular industrial method concerning full aperture easy open ends. The influence of a gradually increasing gap measured between the score and shear force location on traditional groove geometries and depths are examined for two different packaging steels. Earlier studies have shown that the complete opening cycle depends on fracture modes I, II & III as well as their combination. Experimental results for Modes I, II & III will be presented, however attention will focus on the behaviour of the initial fracture point, whereby prior investigations have shown it to be influenced primarily by mode II shearing. After initial specimen manufacture, where the score is formed by pressing a punch into a thin steel sheet the predeformed scored specimens are loaded in shear to simulate the local stress field found during the initial opening phase. Experiments have been completed using a novel Mode II experimental technique that has been designed for use in the majority of commercially available tensile test machines. Experimental results indicate that opening forces can change radically with different gap sizes and that there is considerable potential for the industrialised process of can end manufacture to be optimised through the efficient management and control of the can ends dimensional parameters.

    A self clamping cutting tool which includes a handle attached to a C-shaped housing is described. Rotatably mounted within the housing is a C-shaped tool body carrying a set of clamping rolls, two support rolls, and an edged cutting roll (64). The support rolls are disposed to one side of the axis of a pipe and the cutting roll is disposed to the other side of a pipe axis so that these rolls contact a pipe at three circumferential points. Cutter advancing apparatus advance the cutting roll toward the support rollers. The support rolls and cutting roll are rotatable independently of the C-shaped housing. A one way ratchet mechanism disposed between the C-shaped housing and the C-shaped tool body permits operation by movement in one rotational direction about the pipe axis.

    The current study adopted a participant-informed, "bottom-up," qualitative approach to identifying perceived effects of pornography on the couple relationship. A large sample (N = 430) of men and women in heterosexual relationships in which pornography was used by at least one partner was recruited through online (e.g., Facebook, Twitter, etc.) and offline (e.g., newspapers, radio, etc.) sources. Participants responded to open-ended questions regarding perceived consequences of pornography use for each couple member and for their relationship in the context of an online survey. In the current sample of respondents, "no negative effects" was the most commonly reported impact of pornography use. Among remaining responses, positive perceived effects of pornography use on couple members and their relationship (e.g., improved sexual communication, more sexual experimentation, enhanced sexual comfort) were reported frequently; negative perceived effects of pornography (e.g., unrealistic expectations, decreased sexual interest in partner, increased insecurity) were also reported, albeit with considerably less frequency. The results of this work suggest new research directions that require more systematic attention.

    2013-01-01

    Using a generalized coordinate along with a proper invertible coordinate transformation, we show that the Euler–Lagrange equation used by Bagchi et al (2013 J. Phys. A: Math. Theor. 46 032001) is in clear violation of Hamilton’s principle. We also show that the Newton equation of motion they have used is not in a form that satisfies the dynamics of position-dependent mass (PDM) settings. The equivalence between the Euler–Lagrange equation and Newton’s equation is now proved and documented through the proper invertible coordinate transformation and the introduction of a new PDM byproducted reaction-type force. The total mechanical energy for the PDM is shown to be conservative (i.e., dE/dt = 0, unlike Bagchi et al's (2013) observation). (comment)

    Commenting on a recent editorial in this journal which presented four challenges global health networks will have to tackle to be effective, this essay discusses why this type of analysis is important for global health scholars and practitioners, and why it is worth understanding and critically engaging with the complexities behind these challenges. Focusing on the topics of problem definition and positioning, I outline additional insights from social science theory to demonstrate how networks and network researchers can evaluate these processes, and how these processes contribute to better organizing, advocacy, and public health outcomes. This essay also raises multiple questions regarding these processes for future research. © 2018 The Author(s); Published by Kerman University of Medical Sciences.

    Kunisetti, V. Praveen Kumar; Thippiripati, Vinay Kumar

    2018-01-01

    Open End Winding Induction Motors (OEWIM) are popular for electric vehicles, ship propulsion applications due to less DC link voltage. Electric vehicles, ship propulsions require ripple free torque. In this article, an enhanced three-level voltage switching state scheme for direct torque controlled OEWIM drive is implemented to reduce torque and flux ripples. The limitations of conventional Direct Torque Control (DTC) are: possible problems during low speeds and starting, it operates with variable switching frequency due to hysteresis controllers and produces higher torque and flux ripple. The proposed DTC scheme can abate the problems of conventional DTC with an enhanced voltage switching state scheme. The three-level inversion was obtained by operating inverters with equal DC-link voltages and it produces 18 voltage space vectors. These 18 vectors are divided into low and high frequencies of operation based on rotor speed. The hardware results prove the validity of proposed DTC scheme during steady-state and transients. From simulation and experimental results, proposed DTC scheme gives less torque and flux ripples on comparison to two-level DTC. The proposed DTC is implemented using dSPACE DS-1104 control board interface with MATLAB/SIMULINK-RTI model.

    Full Text Available This paper presents a new dual circularly polarized feed that provides good axial ratio over wide angles and low cross-polarized radiation in backward direction. A circular waveguide open end is fed with two orthogonally polarized waves in phase quadrature by a pair of printed crossed dipoles and a compact connectorized quadrature hybrid coupler. The waveguide aperture is loaded with a dielectric cylinder to reduce the cross-polarization beyond 90 degrees off the boresight. The fabricated feed has, at 5.5 GHz, 6.33-dBic copolarized gain, 3-dB beamwidth of 106°, 10-dB beamwidth of 195°, 3-dB axial ratio beamwidth of 215°, maximum cross-polarized gain of −21.4 dBic, and 27-dB port isolation. The reflection coefficient of the feed is less than −10 dB at 4.99–6.09 GHz.

    This study aimed at estimating the consumer's willingness to pay (WTP) more for value-added pomegranate juice using the contingent valuation method (CVM). The WTP was estimated applying the open-ended elicitation technique with 454 consumers in two supermarkets located in Rio de Janeiro, Brazil. The average consumer's WTP more for pomegranate juice was estimated in R$2.04 (Brazilian currency) and the income elasticity coefficient at the midpoint was 0.19, i.e., a 10% increase in consumer income will increase, on average, 1.9% the WTP of pomegranate juice (ceteris paribus). Therefore, the income elasticity coefficient was considered inelastic, once an increase in income would have low effect on the WTP for these consumers. The results indicated that the consumers were interested in acquiring a non-traditional juice processed using a technology that preserves vitamins and antioxidants, maintains the flavor of "fresh juice" without colorants and preservatives, despite the pomegranate is not part of the Brazilian diet.

    2016-01-01

    Job stress and emotional exhaustion have been shown to have a negative impact on the helping professional. The development and causal relations of job stress and emotional exhaustion are rather unclear in the chiropractic profession. The objective of this study is to understand the main sources of occupational stress and emotional exhaustion among doctors of chiropractic. Analysis of the written responses to web-based open-ended questionnaire was performed using an interpretive research methodology. Additionally, cross tabulation and Chi square statistical tests were conducted to match and couple the demographic data with the categorical themes. Fourteen professional stress categories emerged from the 970 completed surveys. "Managed Care Organization regulation", "Managed Care reimbursement" and "Scope of Practice Issues" were the most common stressors that negatively influenced chiropractors' professional and personal lives. The results of the categorical analysis suggests that age, marital status, number of years in practice and location of practice may have an influence on the category of stress reported by chiropractors. The qualitative approach revealed common, conventional and culture-specific job stressors in doctors of chiropractic. Notably, these findings suggest an association between third-party payer influences (increased regulation/decreased reimbursement) with that of increased job stress. Further research will be undertaken to refine the stress and satisfaction parameters and address stress interventions.

Over the years, I have come to appreciate the great opportunities created by allowing students investigative freedom in physics laboratories. I have realized that a laboratory environment in which students are free to conduct investigations using procedures of their own design can provide them with varied and rich opportunities for discovery. This paper describes what open-ended laboratory investigations have added to my high school physics classes. I will provide several examples of open-ended laboratories and discuss the benefits they conferred on students and teacher alike.

    Dielectric spectroscopy is a measurement technique to characterize the interaction between electromagnetic energy and macroscopic samples as a function of frequency. It is based on the measurement of complex permittivity plus conductivity and it has shown to be very useful to provide information about internal structure of matter. It has some advantages over others like optical or chemical analysis: it is very fast, easy to implement, requires little or no preparation of the sample, it can be non-destructive and/or minimally intrusive. In this paper the development of a dielectric spectroscopy system for the microwave frequency range (50 MHz-20 GHz), using an open-ended coaxial probe as sensor, is described. The complete system includes a vector network analyzer, a microwave coaxial cable, the probe, a sample holder and a computer to automate measurements and further data processing. This system has been used to measure some liquid and solid materials such as alcohol, water and Teflon. The real and imaginary parts of permittivity as function of frequency, for several sugarcane alcohol and deionised water mixtures, tequilas and Teflon samples are given. Measurement repeatability and accuracy considerations were taken and it was identified that uncertainty of reference standards and system repeatability are the most important error sources. Also, it was found that open-ended coaxial probe technique is appropriate for measuring not only liquids but also solid materials. Some of the obtained results were compared to those reported in literature and good convergence was observed.

    2006-10-01

    Full Text Available Abstract Background Long-menu questions (LMQs are viewed as an alternative method for answering open-ended questions (OEQs in computerized assessment. So far this question type and its influence on examination scores have not been studied sufficiently. However, the increasing use of computerized assessments will also lead to an increasing use of this question type. Using a summative online key feature (KF examination we evaluated whether LMQs can be compared with OEQs in regard to the level of difficulty, performance and response times. We also evaluated the content for its suitability for LMQs. Methods We randomized 146 fourth year medical students into two groups. For the purpose of this study we created 7 peer-reviewed KF-cases with a total of 25 questions. All questions had the same content in both groups, but nine questions had a different answer type. Group A answered 9 questions with an LM type, group B with an OE type. In addition to the LM answer, group A could give an OE answer if the appropriate answer was not included in the list. Results The average number of correct answers for LMQs and OEQs showed no significant difference (p = 0.93. Among all 630 LM answers only one correct term (0.32% was not included in the list of answers. The response time for LMQs did not significantly differ from that of OEQs (p = 0.65. Conclusion LMQs and OEQs do not differ significantly. Compared to standard multiple-choice questions (MCQs, the response time for LMQs and OEQs is longer. This is probably due to the fact that they require active problem solving skills and more practice. LMQs correspond more suitable to Short answer questions (SAQ then to OEQ and should only be used when the answers can be clearly phrased, using only a few, precise synonyms. LMQs can decrease cueing effects and significantly simplify the scoring in computerized assessment.

    Natural convection characteristics of a partially heated open ended square cavity have been investigated numerically by using an in-house computational flow solver based on the passive scalar thermal lattice Boltzmann method (PS-TLBM) with D2Q9 (two-dimensional and nine-velocity link) lattice model. The partial part of left wall of the cavity is heated isothermally at either of the three different (bottom, middle and top) locations for the fixed heating length as half of characteristic length (H/2) while the right wall is open to the ambient conditions. The other parts of the cavity are thermally isolated. In particular, the influences of partial heating locations and Rayleigh number (103≤ Ra≤106) in the laminar zone on the local and global natural convection characteristics (such as streamline, vorticity and isotherm contours; centerline variations of velocity and temperature; and local and average Nusselt numbers) have been presented and discussed for the fixed value of the Prandtl number (Pr=0.71). The streamline patterns show qualitatively similar nature for all the three heating cases and Rayleigh numbers, except the change in the recirculation zone which is found to be largest for middle heating case. Isotherm patterns are shifted towards a partially heated wall on increasing Rayleigh number and/or shifting of heating location from bottom to top. Both the local and average Nusselt numbers, as anticipated, shown proportional increase with Rayleigh number. The cavity with middle heating location shown higher heat transfer rate than that for the top and bottom heating cases. Finally, the functional dependence of the average Nusselt number on flow governing parameters is also presented as a closure relationship for the best possible utilization in engineering practices and design.

  13. Comparisons of an open-ended vs. forced-choice 'mind reading' task: implications for measuring perspective-taking and emotion recognition.

    Tracy G Cassels

    Full Text Available Perspective-taking and emotion recognition are essential for successful social development and have been the focus of developmental research for many years. Although the two abilities often overlap, they are distinct and our understanding of these abilities critically rests upon the efficacy of existing measures. Lessons from the literature differentiating recall versus recognition memory tasks led us to hypothesize that an open-ended emotion recognition measure would be less reliant on compensatory strategies and hence a more specific measure of emotion recognition abilities than a forced-choice task. To this end, we compared an open-ended version of the Reading the Mind in the Eyes Task with the original forced-choice version in two studies: 118 typically-developing 4- to 8-year-olds (Study 1 and 139 5- to 12-year-olds; 85 typically-developing and 54 with learning disorders (Study 2. We found that the open-ended version of the task was a better predictor of empathy and more reliably discriminated typically-developing children from those with learning disorders. As a whole, the results suggest that the open-ended version is a more sensitive measure of emotion recognition specifically.

    Beneduci, Amerigo; Chidichimo, Giuseppe

    2012-05-01

    Open-ended waveguide reflectometry is a promising tool for permittivity and other material properties calculation at mm-waves (30-300 GHz). Measurement of the reflection coefficient does not require sample manipulation, allowing in vivo and in vitro non destructive studies on cells. Here we used this technique for measuring the power reflection coefficient (reflectivity) of water and Petri dish supported human skin melanoma and keratinocyte cell cultures, in the 53-72 GHz frequency range. The dependence of the reflectivity on polystyrene or glass thickness of the Petri base plate and on the cell layer thickness was analyzed. Permittivity data were then easily retrieved by using a plane wave-dominant mode approach for formulating the reflectivity at the aperture of the flange-mounted open-ended rectangular waveguide probe. Limits and validity of such an approximate approach were analyzed and compared with full-wave near field formulations for which magnitude and phase of the reflection coefficient must be measured and solved using complicated systems of integral equations and extensive numerical calculation. Finally, Petri dish reflectivity measured by the open-ended waveguide method was compared with that numerically simulated under far-field exposure conditions used in a large number of in vitro studies. Such an analysis showed that, under certain conditions, open-ended reflectivity values approach the far field ones.

    Full Text Available Mathematics is globally valued for use by an individual and society. It plays a significant role in the development of modern science and technology. Despite its importance students motivation to learn and achievement at national examinations globally and at the KCSE mathematics examination in Kenya particularly has been dismal over the years. The learners low achievement in the subject has been attributed to the didactic teaching methods that the teachers use among other factors. The study of geometry in Mathematics poses a number of difficulties to learners which are different in nature from those of arithmetic and algebra. This is because geometry is primarily abstract in nature. The purpose of this study was to determine the effects of Open Ended Teaching and Learning Approach OETLA on Secondary School students mathematics achievement in learning Three Dimensional Geometry 3DG. The study employed Solomon four non-equivalent control group design. The two experimental groups E1amp E2 received OETLA treatment while the control groups C1ampC2 were taught using the conventional teaching and learning methods. Only E1amp C1 took a pre-test and a post test for all the groups. The target population for this study was form four 17 year old students of secondary schools in Marani Sub County in Kisii County. Purposive sampling was used to obtain the four county mixed-sex secondary schools for the study. A total of 152 students formed the sample size. Students Mathematics Achievement Test SMAT was used to collect data. The instruments were validated by three experts from the department of curriculum and instruction of Egerton University and three Secondary School Mathematics Heads of Department. The reliability of the instruments were established using Cronbachs Alpha. A reliability coefficient of 0.92 was obtained and thus considered acceptable. The SMAT was administered to two groups as a pretest before the treatment and as a posttest to all the four

  18. Geographic specificity and positionality of public input in transportation: a rural transportation planning case from Central Texas

    2014-01-01

    Full Text Available Current transportation planning processes often incorporate public input, but the types of engagement techniques can affect the ability of practitioners to meaningfully include local ideas. This study incorporates literature integrating communicative rationality with participatory mapping, supported by a case study focusing on two public engagement techniques. A transportation planning process in Central Texas is evaluated in terms of the geographic specificity and positionality of comments received from open-ended responses on a questionnaire and a facilitated mapping session, and reviews this input for relevance to developing a transportation plan. Although all input received from the public can be valuable in the process, location-based comments may be more actionable by transportation planners. Participants’ perceived roles likely affect their level of engagement, which planners can facilitate to maximize the quality of involvement. Planners are advised to understand the positionality of project stakeholders and professionals, designing involvement methods considering geographic specificity appropriate for each project.

    2012-07-01

    Full Text Available This article reports results from research on cultural models, and assesses the effects of computers on data quality by comparing open-ended questions asked in two formats—face-to-face interviewing (FTFI and computer-assisted, self-interviewing (CASI. We expected that for our non-sensitive topic, FTFI would generate fuller and richer accounts because the interviewer could facilitate the interview process. Although the interviewer indeed facilitated these interviews, which resulted in more words in less time, the number of underlying themes found within the texts for each interview mode was the same, thus resulting in the same models of national culture and innovation being built for each mode. Our results, although based on an imperfect research design, suggest that CASI can be beneficial when using open-ended questions because CASI is easy to administer, capable of reaching more efficiently a large sample, and able to avoid the need to transcribe the recorded responses.

    This study extends the debate on self-rated health by using different sources of data in the same study to explore the meanings of self-rated health among women who live in socio-economically disadvantaged communities in Beirut, Lebanon. Using data from the Urban Health Study, a cross-sectional household survey of 1,869 women between 15 and 59 years of age, multiple logistic regression models were developed to assess factors associated with self-rated health. Also, open-ended data was used to analyze women's explanations of their self-rated health ratings. Self-rated health was found to be a complex concept, associated not only with physical health but also with a combination of social, psychological, and behavioral factors. This open-ended analysis revealed new meanings of self-rated health that are often not included in self-rated health epidemiologic research, such as women's experiences with pain and fatigue, as well as exposure to financial stressors and the legacy of wars. We argue that triangulating survey and open-ended data provides a better understanding of the context-specific social and cultural meanings of self-rated health.

    The Discrete Choice Experiment (DCE) has become increasingly popular as a method for eliciting patient or population preferences. If DCE estimates are to inform health policy, it is crucial that the answers they provide are valid. Convergent validity is tested in this paper by comparing the results of a DCE exercise with the answers obtained from direct, open-ended questions. The two methods are compared in terms of preferred attribute levels and willingness to pay (WTP) values. Face-to-face interviews were held with 292 women in Calgary, Canada. Similar values were found between the two methods with respect to preferred levels for two out of three of the attributes examined. The DCE predicted less well for levels outside the range than for levels inside the range reaffirming the importance of extensive piloting to ensure appropriate level range in DCEs. The mean WTP derived from the open-ended question was substantially lower than the mean derived from the DCE. However, the two sets of willingness to pay estimates were consistent with each other in that individuals who were willing to pay more in the open-ended question were also willing to pay more in the DCE. The difference in mean WTP values between the two approaches (direct versus DCE) demonstrates the importance of continuing research into the different biases present across elicitation methods.

    Gaseous N,N-dimethylformamide (DMF), typical volatile organic compound exhausted from manufacturing factories, may damage the health of workers under long-term exposure even at low levels. The defined geometry, porous surface and highly ordered channels make the free-standing anodic TiO2 nanotube (TiNT) arrays particularly suitable for applications of practical air purification by flow-through photocatalysis. In the present work, crystallized doubly open-ended Ag/TiNT array membranes were designed and prepared by employing a lift-off process based on an anodization-annealing-anodization-etching sequence, followed by uniform Ag nanoparticles decoration. For the photocatalytic degradation of gaseous DMF at low concentration levels close to that found in realistic pollutant air, an analytical methodology for the monitoring and determination of degradation process was developed based on the coupling of headspace sampling with gas chromatography mass spectrometry (HS-GC-MS). The doubly open-ended Ag/TiNT arrays exhibited higher removal efficiency of gaseous DMF from air compared with conventional bottom-closed Ag/TiNT arrays and pure bottomless TiNT arrays. These results indicated that the photocatalytic properties of TiNT arrays were improved with the open-bottom morphology and the Ag nanoparticles decoration. Based on the analysis with GC-MS and high performance ion chromatography (HPIC), it was found that demethylation is the main pathway of DMF degradation in photocatalytic reactions. Furthermore, decontamination of actual polluted tannery waste gas collected in leather factory proved that the photocatalysis on doubly open-ended Ag/TiNT array membrane is an efficient way and a promising application to treat air contaminated by DMF despite the complexity of various volatile organic compounds.

    Nitrate (NO3 -) is an ergogenic nutritional supplement that is widely used to improve physical performance. However, the effectiveness of NO3 - supplementation has not been systematically investigated in individuals with different physical fitness levels. The present study analysed whether different fitness levels (non-athletes v. athletes or classification of performance levels), duration of the test used to measure performance (short v. long duration) and the test protocol (time trials v. open-ended tests v. graded-exercise tests) influence the effects of NO3 - supplementation on performance. This systematic review and meta-analysis was conducted and reported according to the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. A systematic search of electronic databases, including PubMed, Web of Science, SPORTDiscus and ProQuest, was performed in August 2017. On the basis of the search and inclusion criteria, fifty-four and fifty-three placebo-controlled studies evaluating the effects of NO3 - supplementation on performance in humans were included in the systematic review and meta-analysis, respectively. NO3 - supplementation was ergogenic in non-athletes (mean effect size (ES) 0·25; 95 % CI 0·11, 0·38), particularly in evaluations of performance using long-duration open-ended tests (ES 0·47; 95 % CI 0·23, 0·71). In contrast, NO3 - supplementation did not enhance the performance of athletes (ES 0·04; 95 % CI -0·05, 0·15). After objectively classifying the participants into different performance levels, the frequency of trials showing ergogenic effects in individuals classified at lower levels was higher than that in individuals classified at higher levels. Thus, the present study indicates that dietary NO3 - supplementation improves physical performance in non-athletes, particularly during long-duration open-ended tests.

    We report nonperturbing observation of the electric field in the sheet plasma for RF end-plugging on the RFC XX-M open-ended machine by using the Stark effect with a combined technique of beam-probe and laser-induced fluorescence. Under the optimum condition for the RF plugging, enhanced electric field is found in the sheet plasma by about 2.5 times with respect to the electric field when no plasma is produced. The field spatial profile is also measured, which is discussed in connection with the electrostatic eigenmode. (author)

    Full Text Available The present study investigated the extent to which an instructional framework of integrating strategy instruction (open-ended strategy and fill-in-the blanks strategy with motivation- support affected on reading result for young EFL learners. The central area of exploration included a comparison among three approaches to reading instruction: First, fill-in-the blanks strategy intervention; second, open-ended strategy intervention; and last, a control group which received the conventional reading strategies. The participants were sampled from amongst a group of seventy-seven pre-intermediate EFL learners in a language school in Tehran- Iran based on convenient sampling technique. For the sake of measurement, the researchers administered PET and CELT along with reading strategy based-test to quantify the participants’ current level of knowledge as well as the degree of achievement after treatment. For measurement’s sake, different types of tests such as PET, reading comprehension test (CELT, and reading strategy based- test were employed to quantify the participants’ current level of knowledge as well as the degree of achievement before and after instruction. The result of the present study indicated that the experimental groups had a significant improvement over the control group. Also, the level of learners’ reading engagement during classroom work mediated the instructional effects on reading outcomes. The results of this study can be to the benefit of both EFL and ESL teachers to teach reading comprehension using the student's critical mind as well as critical involvement in the reading tasks.

    In our Fundamentals of Genetics lab, students perform a wide variety of labs to reinforce and extend the topics covered in lecture. I developed an active-learning lab to augment the lecture topic of mutagenesis. In this lab exercise, students determine if a compound they bring from home is a mutagen. Students are required to read extensive background material, perform research to find a potential mutagen to test, develop a hypothesis, and bring to the lab their own suspected mutagen. This lab uses a specially developed strain of Saccharomyces cerevisiae, D7, to determine if a compound is a mutagen. Mutagenesis of the D7 genome can lead to a scorable alteration in the phenotypes of this strain. Students outline and carry out a protocol for treatment of the yeast tester strain, utilizing the concept of dose/response and positive and negative controls. Students report on their results using a PowerPoint presentation to simulate giving a scientific presentation. The students' self-assessment of their knowledge indicated that, in all cases, the students felt that they knew more about the assay, mutagenesis, and the relationship between genotype and phenotype (P exercise.

    Full Text Available Mutual funds are one of the key suppliers of liquidity in Romanian capital market. This paper uses quarterly data on Romanian open-end funds starting with 2006 until 2010. We find that significant negative flows (outflows were registered beginning with the end of 2007 (equity funds, during 2008 (equity funds, balanced funds, other funds and bond funds in the last 2 quarters of the year and from 2009 to 2010 (in the case of money market funds. There is evidence that the changing market conditions attract differently the incoming flows in these mutual funds. This is the reason why such perturbations affect investors’ confidence for these investment vehicles and impose the reorientation of the investment funds and of their investors to other alternatives in order to preserve their capital.

A comparative analysis was conducted based on the quartiles of the empirical distributions of the rates of return on selected funds and bank deposits. The empirical distributions were obtained using a moving window of observation. The results were largely influenced by very high interest rates on bank deposits in Poland in the years 1995–2001 (in the case of the oldest funds, and by the boom in the bond market in the years 2011–2012 (for the youngest funds. The investment horizon turned out to be significant. The best and worst funds were identified.

    We systematically investigated the charge transport properties of doubly or singly open-ended TiO2 nanotube arrays (DNT and SNT, respectively) for their utility as electrodes in dye-sensitized solar cells (DSCs). The SNT or DNT arrays were transferred in a bottom-up (B-up) or top-up (T-up) configuration onto a fluorine-doped tin oxide (FTO) substrate onto which had been deposited a 2 μm thick TiO2 nanoparticle (NP) interlayer. This process yielded four types of DSCs prepared with SNTs (B-up or T-up) or DNT (B-up or T-up). The photovoltaic performances of these DSCs were analyzed by measuring the dependence of the charge transport on the DSC geometry. High resolution scanning electron microscopy techniques were used to characterize the electrode cross sections, and electrochemical impedance spectroscopy was used to characterize the electrical connection at the interface between the NT array and the TiO2 NP interlayer. We examined the effects of decorating the DNT or SNT arrays with small NPs (sNP@DNT and sNP@SNT, respectively) in an effort to increase the extent of dye loading. The DNT arrays decorated with small NPs performed better than the decorated SNT arrays, most likely because the Ti(OH)4 precursor solution flowed freely into the array through the open ends of the NTs in the DNT case but not in the SNT case. The sNP@DNT-based DSC exhibited a better PCE (10%) compared to the sNP@SNT-based DSCs (6.8%) because the electrolyte solution flow was not restricted, direct electron transport though the NT arrays was possible, the electrical connection at the interface between the NT array and the TiO2 NP interlayer was good, and the array provided efficient light harvesting.

    267 undergraduate students in an interdisciplinary environmental sustainability course were divided into 66 groups for the duration of the semester. The formation of the groups proceeded by first assigning all of the science majors to groups in a random order. This was followed by assigning the engineering majors, the liberal arts majors, and finally the business majors in turn. After all of the students had been assigned to a group, every group had at least one engineering student and one science student. 11 groups had a liberal arts student but no business student. 26 groups had a business student but no liberal arts student. 29 groups were composed of students from all four majors. During the semester, the groups created an environmental action plan to address one of Singapore's major sustainability concerns: food. In service of the course's emphasis on interdisciplinary communication, the groups were required to create a video to support their environmental action plan. The evaluation method for the videos built on our prior work with rubrics (Hartman & Goodkin, 2016). While we provided a number of examples of videos communicating environmental action plans, students were not prescribed a particular format for their video. To the consternation of some students, the instructor deliberately left the video assessment open-ended. After the semester ended, a researcher coded all 66 videos for the food sustainability issues they identified, their proposed solutions, and their video approach. Approaches included animations, virtual handwriting/drawing, role-playing, PowerPoint presentations, and picture slideshows. Given the open-ended nature of the video project, we hypothesized that groups would converge on approaches that at least one team member was familiar with. We knew from prior work with the business school, that its students engage in role-play activities fairly frequently. Teams with a business major and without a liberal arts major adopted the role

    2012-02-01

    Full Text Available Use of open-ended Problem-Based Learning (PBL in biology classrooms has been limited by the difficulty in designing problem scenarios such that the content learned in a course can be predicted and controlled, the lack of familiarity of this method of instruction by faculty, and the difficulty in assessment. Here we present the results of a study in which we developed a team-based interdisciplinary course that combined the fields of biology and civil engineering across three years. We used PBL scenarios as the only learning tool, wrote the problem scenarios, and developed the means to assess these courses and the results of that assessment. Our data indicates that PBL changed students’ perception of their learning in content knowledge and promoted a change in students’ learning styles. Although no  statistically significant improvement in problem-solving skills and critical thinking skills was observed, students reported substantial changes in their problem-based learning strategies and critical thinking skills.

  1. Views from Within a Narrative: Evaluating Long-Term Human-Robot Interaction in a Naturalistic Environment Using Open-Ended Scenarios.

    This article describes the prototyping of human-robot interactions in the University of Hertfordshire (UH) Robot House. Twelve participants took part in a long-term study in which they interacted with robots in the UH Robot House once a week for a period of 10 weeks. A prototyping method using the narrative framing technique allowed participants to engage with the robots in episodic interactions that were framed using narrative to convey the impression of a continuous long-term interaction. The goal was to examine how participants responded to the scenarios and the robots as well as specific robot behaviours, such as agent migration and expressive behaviours. Evaluation of the robots and the scenarios were elicited using several measures, including the standardised System Usability Scale, an ad hoc Scenario Acceptance Scale, as well as single-item Likert scales, open-ended questionnaire items and a debriefing interview. Results suggest that participants felt that the use of this prototyping technique allowed them insight into the use of the robot, and that they accepted the use of the robot within the scenario.

    Findings conflict as to whether thin-ideal media affect women's body satisfaction. Meta-analyses of experimental studies reveal small or null effects, but many women endorse appearance-related media pressure in surveys. Using a novel approach, two samples of women (Ns=656, 770) were exposed to bikini models, fashion models, or control conditions and reported the effects of the images their body image. Many women reported the fashion/bikini models made them feel worse about their stomachs (57%, 64%), weight (50%, 56%), waist (50%, 56%), overall appearance (50%, 56%), muscle tone (46%, 52%), legs (45%, 48%), thighs (40%, 49%), buttocks (40%, 43%), and hips (40%, 46%). In contrast, few women (1-6%) reported negative effects of control images. In open-ended responses, approximately one-third of women explicitly described negative media effects on their body image. Findings revealed that many women perceive negative effects of thin-ideal media in the immediate aftermath of exposures in experimental settings. Copyright © 2017 Elsevier Ltd. All rights reserved.

    In November 2010 the United Nations General Assembly set up a working group to strengthen the protection of human rights for older persons (UN Open-ended Working Group on Ageing) with the United Nations Resolution A/C.3/65/L.8/Rev.1. In December 2016 the members of the working group met for the seventh time and discussed how they can approach the fulfillment of the mandate. In addition to better implementation, the strengthening of rights can consist of closing existing gaps or further differentiation of the rights in order to give the member states better guidance on how to implement them. To improve the human rights of older persons a task of the members of the working group would be to examine the existing rights and, where possible, adjust them to the real needs of the group. One of the major challenges facing the working group is already apparent: who belongs to the group of older persons and how could the group be described? This article deals with the presentation of the international process, new developments at the regional level and the attitudes of the member states and the civil society. A further aim is to present the possibilities and effects of a comprehensive legally binding instrument.

    The purpose of this study is to investigate the characteristics of mental health problems faced by young workers and the effectiveness of measures implemented for improving their mental health. We sent anonymous open-ended questionnaires to 386 occupational physicians in Japan, and received questionnaire responses from 109 of them. The questionnaire was comprised of two parts. The first part addressed the age-specific characteristics of workers with mental health problems. The second part focused on the mental health measures implemented for young workers and opinions on their effectiveness. The responses were entered in a database. Frequently appearing words were identified and the number of times of the appearance was counted for each question. We conducted statistical analysis to examine the association between word frequency and age group in the first part. Ten investigators and collaborators of this study arranged the descriptions of the mental health measures for young workers and the opinions on their effectiveness in the second part. For mentally ill subjects in their 20s, we identified a range of frequently occurring words using correspondence analysis. The frequently occurring words were: "personality", "immaturity", "extrapunitive", "developmental disorder", "schizophrenia," "new-type depression", "maladjustment", "entering a company", "society", "superior," and "co-worker", Work-related words, such as "qualitative workloads" and "quantitative workloads", were identified for those in their 30s, and greater numbers of words on life outside of the workplace, such as "home," "child" and "nursing care" were identified for those in their 40s. Among the responses about the types of measures implemented for young workers, education and interviews were most common, and most respondents indicated that the effectiveness of these measures was unknown. A few respondents indicated that coordination between young workers' families and the persons concerned in the

    Continuous patient feedback can give important information to hospitals about the quality of care they provide. The Patient Comment Card (PCC), a brief form that can be used to gather open-ended comments from patients and to measure quality, was developed during a two-year period and was extensively evaluated in a series of three pilot tests involving more than 2,000 patients discharged from five hospitals. Evaluation results demonstrate that the questionnaire elicits useful comments from patients and can generate statistically reliable scores and valid quality measures. However, in a field trial in four hospitals, low response rates (15%-27%) reflected, first, lack of follow-up of non-respondents, and second, the fact that most of the PCC quality scores were upwardly biased; these inflated scores were likely to reflect the low response rate. Tools such as the PCC should be used judiciously, given the possible abuses and misinterpretations of hospital quality scores.

  7. Opinion Summarizationof CustomerComments

    Science.gov (United States)

    Fan, Miao; Wu, Guoshi

    Web 2.0 technologies have enabled more and more customers to freely comment on different kinds of entities, such as sellers, products and services. The large scale of information poses the need and challenge of automatic summarization. In many cases, each of the user-generated short comments implies the opinions which rate the target entity. In this paper, we aim to mine and to summarize all the customer comments of a product. The algorithm proposed in this researchis more reliable on opinion identification because it is unsupervised and the accuracy of the result improves as the number of comments increases. Our research is performed in four steps: (1) mining the frequent aspects of a product that have been commented on by customers; (2) mining the infrequent aspects of a product which have been commented by customers (3) identifying opinion words in each comment and deciding whether each opinion word is positive, negative or neutral; (4) summarizing the comments. This paper proposes several novel techniques to perform these tasks. Our experimental results using comments of a number of products sold online demonstrate the effectiveness of the techniques.

    2004-01-01

    Full Text Available The focus of this text is on the multicultural condition, related to the foreignlanguage classroom as a possible arena for democratic experiences. However,due to the increasing ambiguity, to say the least, of the conceptions of “culture”and “multiculturalism” today, I will argue that, depending on how “multicul-turalism” is conceived, this focus may indeed either lead to a cultural andcommunicative closure, or open up the possibility of multi-vocal dialogue andcommunication. If, on the one hand, “multiculturalism” is understood asdifference, mainly constituted by a variety of categorized cultural groupings,you may end up essentializing culture to something that people “have”, andthat is imposed on them collectively from an outside position. If, on the otherhand, cultural differences are seen as constructed within human practices ofongoing narratives and negotiations between individuals and groups – acrossand beyond all kinds of cultural borders – then the hybrid, pluralistic condi-tion of a society, or even of a foreign language classroom, may offer at least anopportunity for cultural identities to co-construct a social space, where nor-mative conflicts and different viewpoints could be dealt with through multi-vocal deliberative communication.

    2017-05-01

    Full Text Available An open-end winding permanent magnet synchronous motor (PMSM has a larger range of speed regulation than normal PMSM with the same DC voltage, and the control method is more flexible. It can also manage energy distribution between two power sources without a DC/DC converter. This paper aims at an electric vehicle equipped with OW-PMSM drive system with dual power sources and dual inverters; based on analyzing the external characteristics of each winding mode, we propose a winding mode switching strategy whose torque saturation judgmental algorithm, which is insensitive to motor’s parameters, could automatically realize upswitching of the winding mode. The proposed multi-level current hysteresis modulation algorithm could set the major power source and switch it at any time in independent mode, which accomplishes energy distribution between two power sources; its two control methods, low switching frequency method and high power difference method, could achieve different energy distribution effects. Simulation results confirm the validity and effectiveness of the winding mode switching strategy and current modulation method. They also show that an electric vehicle under the proposed control methods has better efficiency than one equipped with a traditional OW-PMSM drive system under traditional control.

This study examined whether such evaluative comments with or without uncivil expressions influence evaluations by subsequent viewers. Results showed PSAs with positive (i.e. anti-smoking) comments were perceived by smokers as more effective than PSAs with negative (pro smoking) comments. Smokers in the no comment condition gave the highest perceived effectiveness score to PSAs. Smokers' readiness to quit smoking moderated the effect of comments on PSA evaluation. Smokers reading negative uncivil comments reported more negative attitude toward quitting and a lower level of perceived risk of smoking than those reading negative civil comments but positive civil and positive uncivil comments didn't elicit different responses.

  3. Comments on numerical simulations

    International Nuclear Information System (INIS)

    Sato, T.

    1984-01-01

    The author comments on a couple of things about numerical simulation. One is just about the philosophical discussion that is, spontaneous or driven. The other thing is the numerical or technical one. Frankly, the author didn't want to touch on the technical matter because this should be a common sense one for those who are working at numerical simulation. But since many people take numerical simulation results at their face value, he would like to remind you of the reality hidden behind them. First, he would point out that the meaning of ''driven'' in driven reconnection is different from that defined by Schindler or Akasofu. The author's definition is closer to Axford's definition. In the spontaneous case, for some unpredicted reason an excess energy of the system is suddenly released at a certain point. However, one does not answer how such an unstable state far beyond a stable limit is realized in the magnetotail. In the driven case, there is a definite energy buildup phase starting from a stable state; namely, energy in the black box increases from a stable level subject to an external source. When the state has reached a certain position, the energy is released suddenly. The difference between driven and spontaneous is whether the cause (plasma flow) to trigger reconnection is specified or reconnection is triggered unpredictably. Another difference is that in driven reconnection the reconnection rate is dependent on the speed of the external plasma flow, but in spontaneous reconnection the rate is dependent on the internal condition such as the resistivity

    When designing laboratory courses in a Physics Major we consider a range of objectives: teaching Physics; developing lab competencies; instrument control and data acquisition; learning about measurement errors and error propagation; an introduction to project management; team work skills and scientific writing. But nowadays we face pressure to decrease laboratory hours due to the cost involved. Many universities are replacing lab classes for simulation activities, hiring PhD. and master students to give first year lab classes, and reducing lab hours. This leads to formatted lab scripts and poor autonomy of the students, and failure to enhance creativity and autonomy. In this paper we present our eight year experience with a laboratory course that is mandatory in the third year of Physics and Physical Engineering degrees. Since the students had previously two standard laboratory courses, we focused on teaching instrumentation and giving students autonomy. The course is divided in two parts: one third is dedicated to learn computer controlled instrumentation and data acquisition (based in LabView); the final 2/3 is dedicated to a group project. In this project, the team (2 or 3 students) must develop a project and present it in a typical conference format at the end of the semester. The project assignments are usually not very detailed (about two or three lines long), giving only general guidelines pointing to a successful project (students often recycle objectives putting forward a very personal project); all of them require assembling some hardware. Due to our background, about one third of the projects are related to Optics.

  8. Control of open end plasma flow utilizing orbital stochasticity

    International Nuclear Information System (INIS)

    Hojo, Hitoshi

    1995-01-01

    It has been known that the control of plasma outside the confinement region of diverter plasma and others in a magnetic field confinement device is very important for improveing the confinement of bulk plasma. The control of plasma outside a confinement region bears two roles, one is the reduction of the thermal load on a diverter plate and others due to the plasma particles lost from the confinement region, and another is the restriction of the back flow of cold plasma and impurities generated outside the confinement region to a bulk plasma region. In this study, the new method of controlling plasma outside a confinement region called magnetic diverter is considered. To the plasma particles advancing along magnetic force lines, the reflection and capture of the plasma particles occur in the region of orbital stochasticity, and the thermal load on an end plate and the reverse flow to a bulk plasma region are restricted. The numerical computation model used regarding the particle control utilizing the orbital stochasticity and the results of calculating the orbit of plasma particles in a magnetic field are reported.

    User-centred design is a widely acknowledged practice.

The underlying driver is that the design team will be bett...... interpretations which lead to empathic understanding and engagement. Rather than communicating the final results, design in supporting collaboration is applied in a process of exploring what it is that will create value for specific people....... at designing if they have an empathic understanding of the people to design with and for.

    2004-01-01

    To realize design automation of mechatronic systems, there are two major issues to be dealt with: open-topology generation of mechatronic systems and simulation or analysis of those models. For the first issue, we exploit the strong topology exploration capability of genetic programming to create...... and evolve structures representing mechatronic systems. With the help of ERCs (ephemeral random constants) in genetic programming, we can also evolve the sizing of mechatronic system components along with the structures. The second issue, simulation and analysis of those system models, is made more complex...... when they represent mixed-energy-domain systems. We take advantage of bond graphs as a tool for multi- or mixed-domain modeling and simulation of mechatronic systems. Because there are many considerations in mechatronic system design that are not completely captured by a bond graph, we would like...

  12. Progress In Research On Open - Ended Magnetic Traps

    2006-01-01

    At present, three modern types of mirror machines for plasma confinement and heating exist in Novosibirsk (Multi-mirror,-GOL-3, Gas Dynamic Trap,-GDT, and Tandem Mirror,- AMBAL-M). From the engineering point of view all these systems are very attractive because of simple axisymmetric geometry of magnetic configurations. In this paper, the status of GOL-3 and GDT machines is presented. The most crucial experiments for the mirror concept are described such as a demonstration of different principles of suppression of longitudinal electron heat conductivity (GDT, GOL-3), finding of MHD stable regimes of confinement of high β (more than 0.4) plasma in axisymmetric geometry of magnetic field, an effective heating of a dense plasma (of order of 10 21 m-3) by high current relativistic electron beam (GOL-3), etc. In the case of multi-mirror geometry (GOL-3) significant increase of confinement time of hot plasma (up to several tens times) was obtained in comparison with single mirror geometry. Besides, electron heating (up to 2 keV) in result of high current electron beam -- plasma interaction, the heating of ions (up to 2 keV) was discovered in the multi-mirror geometry (55 mirror cells with total length of the trap equal to 12 meters). There was no any effect of ion heating in the single mirror geometry. The reasons of appearance of the ion heating in multi-mirror geometry are discussed. It should be mentioned that on the basis of the GOL-3 and GDT one can obtain an important information for ITER and for future fusion program. In the case of GOL-3 the longitudinal energy density flux of plasma after heating by REB can be so high as 50 MJ/m2. A lot of experiments can be made on plasma-wall interaction (evaporation, erosion and ionization of wall material, propagation of the impurity ions along magnetic field lines at long distances, etc). Some of these experiments are described in this paper. Using principle of confinement of 'warm' collisional plasma placed in gas dynamic trap (GDT) together with oblique injection of fast atoms of D and T one can create a powerful 14 MeV neutron source for constructed materials tests of future fusion reactors with a moderate irradiation area (about 1 square meter) and, accordingly, with low tritium consumption. It should be mentioned that there is no one candidate to the plasma based neutron source with such moderate consumption of tritium (about 150 gram/year) and electric power (60 MW). The experimental results with NB injection of 4 MW are described and the experiments of the next step (GDT-U) with 10 MW injection are discussed

    There are many commonplace examples of waves moving along a curved path in an inhomogeneous media. There are reports of a simple lecture demonstration of light bending in a sugar solution being used to motivate students in physics, geophysics, and acoustics courses. For those students who wish to pursue this topic we discuss many avenues of additional research. With relatively simple equipment one can measure the index of refraction n (y,t) and its first and second spatial derivatives as well as the time dependence. The analysis can be approached from a generalization of Snell's law, the equations for the eikonal, Fermat's principle, and the classical approximation and analogies with trajectories of particles

    Full Text Available Given the variation in human papillomavirus (HPV vaccine coverage across Canada, and debate regarding delivery of HPV vaccines in Catholic schools, we studied online comments on Canadian news websites to understand public perceptions of HPV and HPV vaccine.We searched English- and French-language Canadian news websites for 2012 articles that contained the terms "HPV" or "human papillomavirus." Articles about HPV vaccinations that contained at least one comment were included. Two researchers independently coded comments, analyzing them for emerging themes.We identified 3073 comments from 1198 individuals in response to 71 news articles; 630 (52.6% individuals expressed positive sentiments about HPV vaccination (2.5 comments/individual, 404 (33.7% were negative (3.0 comments/individual, 34 (2.8% were mixed (1.5 comments/individual and 130 (10.8% were neutral (1.6 comments/individual. Vaccine-supportive commenters believed the vaccine is safe and effective. Common themes in negative comments included concerns regarding HPV vaccine safety and efficacy, distrust of pharmaceutical companies and government, and belief that school-age children are too young for HPV vaccine. Many comments focused on whether the Catholic Church has the right to inform health policy for students, and discussion often evolved into debates regarding HPV and sexual behaviour. We noted that many individuals doubted the credibility of vaccine safety information.The majority of commenters do not appear to be against HPV vaccination, but public health messaging that focuses on both the vaccine's safety profile, and its use as a means to prevent cancer rather than sexually transmitted HPV infection may facilitate its acceptance.

  4. Comment: Reluctance to trade a risky position in oil market

    International Nuclear Information System (INIS)

    Thomas, M.

    1995-01-01

    The oil industry is re-engineering, restructuring, down-sizing, etc. as part of a draconian effort to reduce costs and enhance profit margins. Benchmarking of corporate results against the competition is in vogue, with a view to challenging performance at every level of management. The bold can do attitude behind today's oil industry revolution in management grinds to a halt when the subject is oil trading. Mention speculation, oil pricing mechanisms, market risk-taking, or derivative instruments, and many in senior management and the corporate boardroom lapse into worried silence. When an oil company finishes restructuring and reconcentrating business direction, setting new investment and performance criteria, it is still left with the huge variable of price. Any corporate management that fails to act aggressively in the trading sector by pursuing the best possible oil price as a buyer or seller isn't living up to its responsibilities to shareholders. This article discusses market retreat, market imperfections, winners and losers, the decision to trade, developing a program and issues currently attracting oil industry attention

    Galmarini, M V; Symoneaux, R; Chollet, S; Zamora, M C

    2013-03-01

    Apple consumers' expectations in Argentina and France were studied by comment analysis of open-ended questions. In an on-line survey consumers stated: attributes which defined quality in an apple; visual, flavor and texture characteristics they liked/did not like to find in an apple. Influence of country, consumption frequency and cultivar knowledge were analyzed by contingency tables, Chi-square per cell tests and Multiple Factor Analysis. Consumers' quality expectations were not the same in both countries. Argentineans and French consumers agreed that quality apples should be juicy (most used term in both countries), tasty, firm and fresh. However, for Argentineans quality was more related to visual characteristics, whereas for French it was driven by flavor. Argentineans used more words but French were more specific, particularly for flavour description. Moreover, frequency of consumption, varieties knowledge and the number of terms given were highly related. Frequent consumers knew more varieties and were more prolific in relation to flavour. Less frequent consumers knew fewer apple varieties and gave more words in the visual category. The use of comment analysis allowed identifying the terms that consumers used in their day to day life to describe apples, finding separately likes and dislikes, in spite of the different languages.

    Hefetz, Dan; Stojaković, Miloš; Szabó, Tibor

    2014-01-01

    This text serves as a thorough introduction to the rapidly developing field of positional games. This area constitutes an important branch of combinatorics, whose aim it is to systematically develop an extensive mathematical basis for a variety of two-player perfect information games. These range from such popular games as Tic-Tac-Toe and Hex to purely abstract games played on graphs and hypergraphs. The subject of positional games is strongly related to several other branches of combinatorics such as Ramsey theory, extremal graph and set theory, and the probabilistic method. These notes cover a variety of topics in positional games, including both classical results and recent important developments. They are presented in an accessible way and are accompanied by exercises of varying difficulty, helping the reader to better understand the theory. The text will benefit both researchers and graduate students in combinatorics and adjacent fields.

    Purpose: To enable to detect the position of an moving object in a control rod position detector, stably in a digital manner at a high accuracy and free from the undesired effects of circumstantial conditions such as the reactor temperature. Constitution: Coils connected in parallel with each other are disposed along the passage of a moving object and variable resistors and relays are connected in series with each of the coils respectively. Light emitting diodes is connected in series with the contacts of the respective relays. The resistance value of the variable resistors are adjusted depending on the changes in the circumstantial conditions and temperature distribution upon carrying out the positional detection. When the object is inserted into a coils, the relevant relay is deenergized, by which the relay contacts are closed to light up the diode. In the same manner, as the object is successively inserted into the coils, the diodes are lighted-up successively thereby enabling highly accurate and stable positional detection in a digital manner, free from the undesired effects of the circumstantial conditions.

    Yang Lei

    Full Text Available The aim of this study was to understand online public perceptions of the debate surrounding the choice of annual influenza vaccinations or wearing masks as a condition of employment for healthcare workers, such as the one enacted in British Columbia in August 2012.Four national and 82 local (British Columbia Canadian online news sites were searched for articles posted between August 2012 and May 2013 containing the words "healthcare workers" and "mandatory influenza vaccinations/immunizations" or "mandatory flu shots and healthcare workers." We included articles from sources that predominantly concerned our topic of interest and that generated reader comments. Two researchers coded the unedited comments using thematic analysis, categorizing codes to allow themes to emerge. In addition to themes, the comments were categorized by: 1 sentiment towards influenza vaccines; 2 support for mandatory vaccination policies; 3 citing of reference materials or statistics; 4 self-identified health-care worker status; and 5 sharing of a personal story.1163 comments made by 648 commenters responding to 36 articles were analyzed. Popular themes included concerns about freedom of choice, vaccine effectiveness, patient safety, and distrust in government, public health, and the pharmaceutical industry. Almost half (48% of commenters expressed a negative sentiment toward the influenza vaccine, 28% were positive, 20% were neutral, and 4% expressed mixed sentiment. Of those who commented on the policy, 75% did not support the condition to work policy, while 25% were in favour. Of the commenters, 11% self-identified as healthcare workers, 13% shared personal stories, and 18% cited a reference or statistic.The perception of the influenza vaccine in the comment sections of online news sites is fairly poor. Public health agencies should consider including online forums, comment sections, and social media sites as part of their communication channels to correct

    The covariance matrix of a scattered data set, x_i (i=1,n), must be symmetric and positive-definite. As one of WPEC/SG39 contributions to the SG40/CIELO project, several comments or recommendations on the covariance data are described here from the viewpoint of nuclear-data users. To make the comments concrete and useful for nuclear-data evaluators, the covariance data of the latest evaluated nuclear data library, JENDL-4.0 and ENDF/B-VII.1 are treated here as the representative materials. The surveyed nuclides are five isotopes that are most important for fast reactor application. The nuclides, reactions and energy regions dealt with are followings: Pu-239: fission (2.5∼10 keV) and capture (2.5∼10 keV), U-235: fission (500 eV∼10 keV) and capture (500 eV∼30 keV), U-238: fission (1∼10 MeV), capture (below 20 keV, 20∼150 keV), inelastic (above 100 keV) and elastic (above 20 keV), Fe-56: elastic (below 850 keV) and average scattering cosine (above 10 keV), and, Na-23: capture (600 eV∼600 keV), inelastic (above 1 MeV) and elastic (around 2 keV)

    The media has the ability to affect public opinion and policy direction. Prevalence of morbid obesity in Canada is increasing; as is the only effective long-term treatment, weight loss surgery (WLS). Limited research has explored media re/presentations of WLS. The purpose of this study was to examine national online news coverage (and reader comments) of WLS using content analysis. We sought to understand the dominant messages being conveyed within the news texts and reader comments, specifically whose voice was represented, who was the intended audience and what was the overall tone. Articles and comments were retrieved from the Canadian Broadcasting Corporation news web site and analysed using line-by-line techniques. Articles were predominantly 'positive/supportive' (63%) in tone and frequently presented the voices and opinions of 'experts' conveying a biomedical perspective. Comments were overwhelmingly 'negative' (56%) and often derogatory including such language as 'piggy' and 'fatty'. Comments were almost exclusively anonymous (99%) and were frequently directed at other commenters (33%) and 'fat' people (6%). The potentially problematic nature of media framing and reader comments, particularly as they could relate to weight-based stigmatization and discrimination is discussed. © 2012 The Authors.

  1. Comments on EPA's LLW preproposal

    International Nuclear Information System (INIS)

    Littleton, B.K.; Weinstock, L.

    1995-01-01

    The Environmental Protection Agency (EPA) is currently developing standards for the management, storage, and disposal of Low-Level Radioactive Waste (LLW). The Atomic Energy Act delegated EPA, among other provisions, the authority to establish generally applicable standards for the disposal of radioactive waste to ensure that the public and the environment are adequately protected from potential radiation impacts. As an initial effort to open communications on a standard for LLW, the Agency developed a preproposal draft (Preproposal Draft of 40 CFR Part 193 - 30 Nov 94) and circulated it to interested parties for review and comment. The extended comment period ended April 12, 1995. A summary of the comments received and analyzed to date follows. After all comments have been analyzed, the rule will undergo an Agency clearance process and be sent to the Office of Management and Budget for review. After that review, the formal process of publication of the proposed rule in the Federal Register and the formal public comment period will begin

    In a recent paper (Z. Banggu, Phys. Rev. A 42, 761 (1990)) it is argued that some solutions of the Boltzmann equation do not satisfy particle conservation as a consequence of the independence of velocity on position. In this comment, the arguments and conclusions of that paper are discussed. In particular, it is stressed that the temporal series used for solving the kinetic equation are generally divergent. A discussion about the particle conservation in its solutions is also provided. (author). 4 refs

    Parenting an LGBTQ (lesbian, gay, bisexual, transgender, or queer) identified child presents unique opportunities for growth and development. This study focused on self-reported perceptions of the positive aspects of being the parent of an LGBTQ child. Participants (N = 142) were mothers (83.8%) and fathers (16.2%) of LGBTQ identified individuals who responded to an open-ended online survey. Thematic analysis revealed five primary themes: Personal Growth (open mindedness, new perspectives, awareness of discrimination, and compassion), Positive Emotions (pride and unconditional love), Activism, Social Connection, and Closer Relationships (closer to child and family closeness). The practice implications of these findings for supporting parents in envisioning positive relationship outcomes for themselves and their children are highlighted in the discussion. © FPI, Inc.

    This study investigates how personality traits in combination with frequency of and emotional reaction to negative comments about appearance while growing up are related to appearance evaluation and orientation among adult women. Nine hundred and seven participants from a representative sample of Norwegian women aged 22-55, answered questions measuring body image, personality (Big Five), and history of experiencing negative comments about appearance. Results indicated that only emotional reaction to negative comments about appearance significantly predicted both appearance evaluation and orientation, while frequency of negative comments did not. Being extrovert predicted more positive appearance evaluation and being more appearance oriented than being introvert. Scoring high on neuroticism was related to negative appearance evaluation and high appearance orientation. The findings demonstrate the importance of differentiating between the frequency and the emotional impact of teasing as well as including personality traits when studying body image.

  7. Contagious comments: what was the online buzz about the 2011 Quebec measles outbreak?

    Directory of Open Access Journals (Sweden)

    Jennifer A Pereira

    Full Text Available BACKGROUND: Although interruption of endemic measles was achieved in the Americas in 2002, Quebec experienced an outbreak in 2011 of 776 reported cases; 80% of these individuals had not been fully vaccinated. We analyzed readers' online responses to Canadian news articles regarding the outbreak to better understand public perceptions of measles and vaccination. METHODS: We searched Canadian online English and French news sites for articles posted between April 2011 and March 2012 containing the words "measles" and "Quebec". We included articles that i concerned the outbreak or related vaccination strategies; and ii generated at least ten comments. Two English and two bilingual researchers coded the unedited comments, categorizing codes to allow themes to emerge. RESULTS: We analyzed 448 comments from 188 individuals, in response to three French articles and six English articles; 112 individuals expressed positive perceptions of measles vaccination (2.2 comments/person, 38 were negative (4.2 comments/person, 11 had mixed feelings (1.5 comments/person, and 27 expressed no opinion (1.1 comments/person. Vaccine-supportive themes involved the success of vaccination in preventing disease spread, societal responsibility to vaccinate for herd immunity, and refutation of the autism link. Those against measles vaccination felt it was a personal rather than societal choice, and conveyed a distrust of vaccine manufacturers, believing that measles infection is not only safe but safer than vaccination. Commenters with mixed feelings expressed uncertainty of the infection's severity, and varied in support of all vaccines based on perceived risk/benefit ratios. CONCLUSION: The anti-vaccine minority's volume of comments translates to a disproportionately high representation on online boards. Public health messages should address concerns by emphasizing that immunization is always a personal choice in Canada, and that the pharmaceutical industry is strictly

  10. A theorem on the methodology of positive economics

    Directory of Open Access Journals (Sweden)

    Eduardo Pol

    2015-12-01

    Full Text Available It has long been recognized that the Milton Friedman’s 1953 essay on economic methodology (or F53, for short displays open-ended unclarities. For example, the notion of “unrealistic assumption” plays a role of absolutely fundamental importance in his methodological framework, but the term itself was never unambiguously defined in any of the Friedman’s contributions to the economics discipline. As a result, F53 is appealing and liberating because the choice of premises in economic theorizing is not subject to any constraints concerning the degree of realisticness (or unrealisticness of the assumptions. The question: “Does the methodology of positive economics prevent the overlapping between economics and science fiction?” comes very naturally, indeed. In this paper, we show the following theorem: the Friedman’s methodology of positive economics does not exclude science fiction. This theorem is a positive statement, and consequently, it does not involve value judgements. However, it throws a wrench on the formulation of economic policy based on surreal models.

  15. They Came, They Liked, They Commented: Social Influence on Facebook News Channels.

    Winter, Stephan; Brückner, Caroline; Krämer, Nicole C

    2015-08-01

    Due to the increasing importance of social networking sites as sources of information, news media organizations have set up Facebook channels in which they publish news stories or links to articles. This research investigated how journalistic texts are perceived in this new context and how reactions of other users change the influence of the main articles. In an online experiment (N=197), a Facebook posting of a reputable news site and the corresponding article were shown. The type of user comments and the number of likes were systematically varied. Negative comments diminished the persuasive influence of the article, while there were no strengthening effects of positive comments. When readers perceived the topic as personally relevant, comments including relevant arguments were more influential than comments with subjective opinions, which can be explained by higher levels of elaboration. However, against expectations of bandwagon perceptions, a high number of likes did not lead to conformity effects, which suggests that exemplifying comments are more influential than statistical user representations. Results are discussed with regard to effects of news media content and the mechanisms of social influence in Web 2.0.

  16. [Comment on] Statistical discrimination

    Science.gov (United States)

    Chinn, Douglas

    In the December 8, 1981, issue of Eos, a news item reported the conclusion of a National Research Council study that sexual discrimination against women with Ph.D.'s exists in the field of geophysics. Basically, the item reported that even when allowances are made for motherhood the percentage of female Ph.D.'s holding high university and corporate positions is significantly lower than the percentage of male Ph.D.'s holding the same types of positions. The sexual discrimination conclusion, based only on these statistics, assumes that there are no basic psychological differences between men and women that might cause different populations in the employment group studied. Therefore, the reasoning goes, after taking into account possible effects from differences related to anatomy, such as women stopping their careers in order to bear and raise children, the statistical distributions of positions held by male and female Ph.D.'s ought to be very similar to one another. Any significant differences between the distributions must be caused primarily by sexual discrimination.

    International Nuclear Information System (INIS)

    Hawking, S.W.

    1979-01-01

    The cosmic censorship hypothesis and the closely related positive energy conjecture are the most important unsolved problems in classical general relativity. Roughly speaking the hypothesis is that nonsingular asymptotically flat initial data on a spacelike surface give rise to a solution in which any singularities that occur are not visible from infinity. Thus the solution near infinity would be unaffected by the breakdown of predictability associated with the singularities. A more precise formulation is given. The evidence for the censorship is mainly negative and this is discussed. The relationship of the hypothesis to quantum gravity and the quantum evaporation of black holes is also mentioned. (UK)

  20. Self-Governance on Trial: A Public Sphere Analysis of News Website Forum Comments

    Directory of Open Access Journals (Sweden)

    J. David Wolfgang

    2016-04-01

    Full Text Available The online public sphere offers society an opportunity to pursue self-governance through rational-critical discourse of public issues. However, testing the effectiveness of the sphere involves studying the structure of the online forum (e.g. whether the forum allows for pseudonymous comments or not and the quality of the content in the forum. This research studied online news forums on the topics of gun control and civil unions in Colorado to see what barriers to participating in the forum might exist in the structure of the forum and then what types of content was produced in the forum. The research showed that a forum allowing commenters to use a pseudonym led to comments with more exchange and critique of reasoned normative positions and use of supporting facts. However, neither the pseudonymous forum nor the identified forum had stronger levels of commitment to constructive dialogue in the forum. Also, commenters showed no reflexivity in their comments, meaning that participants were not assessing their own positions or changing their perspectives based on the arguments of others. While this shows that reducing barriers to accessing the forum helps to produce a public sphere environment, there is still work to be done in improving the level of constructive dialogue and stimulating negotiation and consensus building.

    With the development of e-commerce, various comments based on tags are generated, how to extract valuable information from these comment tags has become an important content of business management decisions. This study takes HUAWEI mobile phone tags as an example using the sentiment analysis and topic LDA mining method. The first step is data preprocessing and classification of comment tag topic mining. And then make the sentiment classification for comment tags. Finally, mine the comments again and analyze the emotional theme distribution under different sentiment classification. The results show that HUAWEI mobile phone has a good user experience in terms of fluency, cost performance, appearance, etc. Meanwhile, it should pay more attention to independent research and development, product design and development. In addition, battery and speed performance should be enhanced.

  8. Public comment sentiment on educational videos: Understanding the effects of presenter gender, video format, threading, and moderation on YouTube TED talk comments.

    Directory of Open Access Journals (Sweden)

    George Veletsianos

    Full Text Available Scholars, educators, and students are increasingly encouraged to participate in online spaces. While the current literature highlights the potential positive outcomes of such participation, little research exists on the sentiment that these individuals may face online and on the factors that may lead some people to face different types of sentiment than others. To investigate these issues, we examined the strength of positive and negative sentiment expressed in response to TEDx and TED-Ed talks posted on YouTube (n = 655, the effect of several variables on comment and reply sentiment (n = 774,939, and the projected effects that sentiment-based moderation would have had on posted content. We found that most comments and replies were neutral in nature and some topics were more likely than others to elicit positive or negative sentiment. Videos of male presenters showed greater neutrality, while videos of female presenters saw significantly greater positive and negative polarity in replies. Animations neutralized both the negativity and positivity of replies at a very high rate. Gender and video format influenced the sentiment of replies and not just the initial comments that were directed toward the video. Finally, we found that using sentiment as a way to moderate offensive content would have a significant effect on non-offensive content. These findings have far-reaching implications for social media platforms and for those who encourage or prepare students and scholars to participate online.

    2017-08-01

    Medical and public health societies advocate that healthcare providers (HCPs) counsel at-risk patients to reduce firearm injury risk. Anonymous online media comments often contain extreme viewpoints and may therefore help in understanding challenges of firearm safety counseling. To help inform injury prevention efforts, we sought to examine commenters' stated opinions regarding firearm safety counseling HCPs. Qualitative descriptive analysis of online comments posted following news items (in May-June, 2016) about a peer-reviewed publication addressing when and how HCPs should counsel patients regarding firearms. Among 871 comments posted by 522 individuals, most (57%) were generally negative toward firearm discussions, 17% were positive, and 26% were neutral/unclear. Two major categories and multiple themes emerged. "Areas of agreement" included that discussions may be valuable (1) when addressing risk of harm to self or others, (2) in pediatric injury prevention, and (3) as general safety education (without direct questioning), and that (4) HCPs lack gun safety and cultural knowledge. "Areas of tension" included whether (1) firearms are a public health issue, (2) counseling is effective prevention practice, (3) suicide could/should be prevented, and (4) firearm safety counseling is within HCPs' purview. Among this set of commenters with likely extreme viewpoints, opinions were generally negative toward firearm safety conversations, but with some support in specific situations. Providing education, counseling, or materials without asking about firearm ownership was encouraged. Engaging firearm advocates when developing materials may enhance the acceptability of prevention activities.

    Physics...fun? 'Physics is Fun' - it's a book, a course, a summer school... Physics, with a reputation for hard maths, nonsensical equations and crazy teachers living with a permanent bad hair day, yes, PHYSICS IS FUN! Maybe if we say it often enough our students will believe us. PHYSICS IS FUN! Keep saying it, and try to believe it. But we are scientists, and we have to look at the evidence and acknowledge the truth: when most people recall the fun times they had at school-how many think about their physics classes? Try asking them. Let's face it - although our students enjoy our exciting demonstrations, the well-structured development of concepts in our classes, and the cooperative and supportive atmosphere of our classrooms and laboratories, even when they find that their physics teachers are the most kind, considerate and approachable of people, even then, when we've done all we can to make physics pleasant, fun and exciting, our students have to fathom out physics... and that can be hard! 'Physics isn't fun in the trivial sense, it's hard work: but you get a fantastic sense of achievement when you make progress.' This is my counsel to most young people who come to discuss whether or not to opt for physics. We try our best to make the material accessible and interesting, but at the end of the day, struggling with something that intially you can't do, but eventually you can do, is part of developing in physics. But what about the teachers? November's meeting of physics teachers from across Europe, Physics on Stage, featured many of the best innovations in physics teaching from the 22 countries which sent delegations (see News). It is probably no surprise, but we need to take note that the most popular stands, talks and lectures were the ones which were most fun. And there is lots of fun to be had doing physics. Whether it is toys, music, poetry, or simply talking about the symmetry in particle physics-the most popular stands, workshops and lectures were those where teachers could enjoy the fun in physics again. Even physics teachers are human! It is so easy to get bogged down in the drudge of everyday teaching and forget the students, let alone ourselves. But if you think back to the good teachers you had at school - weren't they the ones who were enjoying themselves, and maybe not perfectly organized. There has to be a moment at which a good teacher says 'I'm going to do this, because I want to... it's fun physics!' No other justification is needed. Our new look for 2001 So here is the first issue of the new-look Physics Education - and we sincerely hope that you enjoy it. The Editorial Board and the publishing team have been working hard for the past few months to keep the best of the old format, but to make a fresher, more user-friendly publication. As incoming Editor I must acknowledge the excellent work done by Ken Dobson and Jill Membrey, the outgoing team. It is a tough act to follow, but a challenge I am privileged to undertake. As a physics teacher I know how difficult it can be to stay inspired and up-to-date, so as Editor of Physics Education I want to support your professional development as much as possible. Starting with support for student teachers (see Starting Out), through to teachers in charge of equipment and budgets (see Technical Trimmings and Reviews): we want to share good practice. Finally, let's laugh at ourselves-don't miss Signing Off: a humorous look at physics teaching. I've really enjoyed working on this new format, and I hope that you enjoy the read. Please give us lots of feedback and send in your own contributions. I'm very pleased that our first issue has two special features: to me they represent the potential and the purpose of physics education. Sport is an exciting growth area of science in which increasing numbers of students want to understand the basic laws of motion and the application of sophisticated technology; and communicating physics - well that's not just fun, it's fundamental.

    Our opening article in this issue celebrates the first operation, on 1 March, of the proton synchrotron at the National Accelerator Laboratory, Batavia, at its design energy of 200 GeV. The article gives a short description of the machine and some of its building and commissioning story. It is a great achievement to reach the highest energy in the world from a particle accelerator and NAL have done it in a style which is all their own.

    Virtual reality - whose reality? There is an old joke about a farmer who wanted to improve his milk yields and employed an engineer, a psychologist and a physicist to make suggestions. They all went away for a month and came back with their proposals. The engineer had measured the size of the milking stalls, the ambient temperature and the milking process. She suggested a modest rise in ambient temperature and an alteration in the pumping equipment. The psychologist decided to paint the stalls green and play a tape-recording of birdsong to the cows to make them feel more content and release their milk more easily. The physicist explained that he had decided to look at things more fundamentally: 'Let us assume that the cow is a sphere' ... he began. And that's the joke. Some people think that this is the funniest thing out - a physicist can't recognize a cow when they see one. What troubles me is that I didn't get the joke straight away. I am so used to the language and the often-ludicrous assumptions in physics that it did not seem particularly strange or funny. What did you think? The joke, for me, illustrates the essence of our problem in physics teaching. In a very real way, physics is about another world. It isn't about the real world in which ordinary people live, and they know it. Physics has its own language, its own laws and its own values. Depleted uranium has been in the news of late. It is interesting to compare the casual way in which physics teachers have discussed the possibilitiy that one atom of uranium can kill someone with the shock-horror reporting of this fact in the press. We are caricatured, sometimes for good reason, being callous, calculating, cold people - out of touch with the things that really matter. And then there's that other 'real world' - of really tough people who make serious money. Our friends who work out in the worlds of commerce and industry like to mutter, with some superiority, that teachers would never survive in the real world. So here we are, buffered from the 'reality' of commerce by kind managers, left to teach equations at the expense of moral standards ... Excuse me! Physics is the only subject that confronts real reality head on. Physics is all about how this world, this Universe, this reality works. Moral laws, government legislation and theories of economics are all well, and sometimes good, but they take place within this space we call Our Universe. Physics is real This issue of Physics Education contains lots of excellent suggestions for practical work - demonstrations of what happens, and suggestions for investigations. I hope that readers will find them useful and maybe share some good ideas of their own. We are dealing with stuff that actually happens, and that is what makes physics both significant and attractive. The joke I really hate runs 'If it moves it's biology, if it smells it's chemistry and if it doesn't work it's physics'. This is rubbish: gravity always works, in my experience, physics never gets it wrong. In the classroom, maybe a piece of equipment is broken, or the technician forgot the batteries, but we can never say truthfully that 'the experiment didn't work'. Virtual physics Last week a school governor challenged me to justify the cost of so much laboratory space and equipment when, nowadays, so much can be done using computers. Probably the best 'virtual physics' currently available is on CD-ROM. In this issue of Physics Education we have concentrated on CDs for our review section. There is lots of good material out there which can enhance our teaching with wonderful images, immediate feedback for students, and the possibility of continuously monitored differentiated work but, as I explained to the governor, I don't want to teach virtual physics - physics is very firmly, fairly and squarely in this real world (which may, of course, approximate to a sphere ... .).

    In the UK, the Chairwoman of the Family Planning Association (FPA) praises the staff and volunteers with whom she has worked for their incessant inability to meet the many challenges they face. During her 6 years, however, the FPA had to reduce the number of regional offices and staff. It did not need to reduce salaries, however. FPA membership directly elects the National Executive Council which is now smaller. FPA is exploring new sources of funding and is adapting to the purchaser/provider relationship in the statutory sector, resulting in its successful financial strategy. The Department of Health helps in maintaining FPA's ability to continue to operate. The Chairwoman sees indications of needing to fight old battles again, e.g., some officials have suggested limiting the range of oral contraceptives available from prescription by the National Health Services (NHS) which would be the end of almost 20 years of free contraception and free choice under the NHS. The government is not open to including sex education the school curriculum. The NHS gives the impression in its report "The Health of the Nation" that it is committed to reducing adolescent pregnancies among the youngest teenagers and to recognizing the importance of good policies on sexual health. Yet, its actions exhibit no compassion for single parents. Participants at FPA's 1992 conference agree that variety, quality, and sensitivity of family planning provisions are needed and that family planning clinics and general practitioners should work together. FPA has contributed to the UK the clinic network; the concept of family planning being an integral part of a comprehensive health service; and the notion that family planning includes contraception, empowerment of women, sexual health, rights, and responsibilities. FPA should reaffirm these ideas and secure the future for informed choice and planned pregnancy.

    We would like to thank all the experts for their insightful and very interesting comments that have been submitted in response to our review "Network science of biological systems at different scales" [1]. We are delighted with the number of comments that have been written, and even more so with the positive opinions that these comments communicate to the wider audience [2-9]. Although methods of network science have long proven their value in relevantly addressing various challenges in the biological sciences, such interdisciplinary research often still struggles for funding and recognition at many academic levels.

  18. Stylistic Features of Comment in Arabic Blogosphere

    Full Text Available One of the most important issues in the study of the functioning of the Internet language is the definition of the features of each Internet genre presented in online communication, taking into account the linguocultural features of the language in question. This paper studies the genre of the Internet comments of the Arabic-speaking blogosphere and reveals its stylistic features. The most common goal of the comment is gratitude, followed by praise. We created a corpus of comments from blogs of various subjects, and then conducted the tagging, having identified the group to which we attributed a comment, depending on the subject and the communicative goal. With the help of the Lexico 3 software, the most frequent lexical units were identified, the lexical features of the comments were described, the main one being the widespread use of religionyms, and the relationship between the blog subject and the stylistic characteristics of communication was revealed. The article traces the correlation between the literary and colloquial functional style in the comments, and also draws a conclusion that the comments are of a conversational, informal character. The main devices of expressiveness that are characteristic for both network and pre-network communication were revealed, and the tendency of the analysts to observe in the comments a stable three-part composition (greeting, message, final formula. The influence of traditional Arabic rhetoric, as well as the epistolary genre, was preserved. The results of the paper can be used when studying other genres of Internet communication in Arabic and in comparative studies to create the linguistic software.

    To understand current public perceptions of in vitro meat (IVM) in light of its potential to be a more environmentally sustainable alternative to conventional meat. A qualitative content analysis of the comments made on online news articles highlighting the development of IVM and the world's first IVM hamburger in August 2013. News article comment sections across seven US-based online news sources (The New York Times, The Los Angeles Times, The Washington Post, The Wall Street Journal, USA Today, Cable News Network and National Public Radio). Four hundred and sixty-two commenters who made eight hundred and fourteen publicly available online comments addressing IVM. Key themes in commenter perceptions of IVM included environmental and public health benefits, but also negative themes such as IVM's status as an unnatural and unappealing food. Overall, the tone of comments was more negative than positive. Findings suggest that while the environmental and public health motivations for developing and in turn consuming IVM resonate with some segments of the population, others find that reasoning both uncompelling and problematic. Concerns about IVM as an unnatural and risky product also appear to be a significant barrier to public acceptance of IVM. Supporters of IVM may wish to begin to develop a regulatory strategy for IVM to build public trust and explore messaging strategies that cast IVM as a new technology with benefits to individuals rather than primarily a solution to global challenges. Those in the public health nutrition field can make an important contribution to the emerging public discussion about IVM.

    The aim of this study was to better understand the utility of using the Parents' Evaluation of Developmental Status (PEDS) in well-child visits by analyzing themes and patterns in parents' written responses on the PEDS form. We reviewed a consecutive sample of medical records with PEDS forms for children aged 6 months to 9 years (site 1) and 3 to 5 years (site 2). We recorded the concerns that parents identified in response to the 10 PEDS questions along with demographic information. We then categorized parents' written comments about those concerns according to comment content. We used qualitative and quantitative methods for analysis. We collected 752 PEDS forms. Ninety percent of the parents endorsed at least 1 concern (94.6% on the English forms versus 69.7% on the Spanish forms; P Parents qualified 27.5% of their concerns with a written comment. In 23.9% of cases in which parents identified a concern and provided a written comment, the content of the comment did not match the question's intent; rates of mismatch were similar for the English and Spanish forms. Among comments regarding behavioral concerns, 12% reflected a misunderstanding of age-appropriate behavior. Medical concerns accounted for 14.1% of the comments; these concerns were more common on English forms (61.3%) than on Spanish forms (1.7%) (P Parents frequently used the PEDS forms to communicate additional concerns regarding their child or provide positive feedback on their child's progress. The inappropriate developmental expectations, limited health literacy, and culturally distinct comments on the PEDS forms reinforce the importance of using screening tools to enhance the care provided during visits but not to replace patient-provider communication.

    The purpose of this study was to explore the experiences of internationally educated nurses in management positions in United States health care organisations to understand the obstacles and support these individuals' experience when pursuing and working in managerial roles. Although internationally educated nurses are an integral part of the US health care industry, few work in managerial roles. Little is known about the experiences of internationally educated nurses who do obtain management positions. In this qualitative, phenomenological study, seven internationally educated nurses who were managers in Chicago, Illinois, responded to open-ended interview questions. Supervisors contributed to the participants' acceptance of management positions. The participants experienced challenges such as cultural differences, language, and communication. Despite these challenges, the participants had positive working relationships with staff and supervisors. Further, the participants had opportunities for education and professional growth. Internationally educated nurses benefit from participating in organisational committees. They face challenges related to work responsibilities, cultural differences and communication but can succeed in management roles through developing strategies to overcome the challenges and through receiving support from staff, colleagues and supervisors. More internationally educated nurses may obtain managerial positions if supervisors provide encouragement and support. © 2018 John Wiley & Sons Ltd.

  5. Engaging a state: Facebook comments on a large population biobank.

    Scholarship on newborn screening, dried bloodspot retention, and large population biobanking call consistently for improved public engagement. Communication with participants likely occurs only in the context of collection, consent, or notification, if at all. We ran an 11-week advertising campaign to inform Michigan Facebook users unlikely to know that their or their children's dried bloodspots (DBSs) were stored in a state biobank. We investigated the pattern and content of comments posted during the campaign, focusing on users' questions, attitudes and concerns, and the role the moderator played in addressing them. We used Facebook data to quantitatively assess engagement and employed conventional content analysis to investigate themes, attitudes, and social dynamics among user and moderator comments. Five ad sets elicited comments during campaign weeks 4-8, reaching ∼800,000 Facebook users ($6000). Gravitating around broad, underlying ethical, legal, and social issues, 180 posts from 129 unique users related to newborn screening or biobanking. Thirty six conveyed negative attitudes and 33 conveyed positive attitudes; 53 posed questions. The most prevalent themes identified were consent, privacy, bloodspot use, identifiability, inclusion criteria, research benefits, (mis)trust, genetics, DBS destruction, awareness, and the role of government. The moderator's 81 posts were responsive-answering questions, correcting or clarifying information, or providing information about opting out. Facebook ad campaigns can improve engagement by pushing out relevant content and creating dynamic, responsive, visible forums for discussion. Reduced control over messaging may be worth the trade-off for creating accessible, transparent, people-centered engagement on public health issues that are sensitive and complex.

  6. Downsizing of health-system pharmacist positions.

    1998-11-15

    The effects of downsizing on institutional pharmacists were studied. A national mail survey was sent to a random sample of 533 members of ASHP in January 1997. The questionnaire was designed to determine (1) the influence of selected factors on the downsizing of pharmacist positions and (2) pharmacists' attitudes about downsizing. A total of 256 usable questionnaires were received, for a net response rate of 48%. Forty-four pharmacists, or 17%, had personally been affected by downsizing. Sixty-one percent of the pharmacists affected by downsizing had had administrative positions. After downsizing, only 32% of the pharmacists had an administrative position. Most of the pharmacists were currently employed. Thirty-five (79%) described their current job responsibilities as substantially changed. Two thirds made the same salaries or higher salaries. Pharmacists who had been downsized rated mergers, the impact of managed care, and the profit motive as the most influential causes of downsizing of pharmacist positions. The three most common negative comments about the impact of downsizing cited reduction in the quality of patient care, increased stress, and lowered morale. Most of the pharmacists believed that communication skills, education, cross-training, and clinical skills are keys to surviving downsizing. Most pharmacists whose positions were downsized said they went on to jobs with similar or higher salaries and substantially different responsibilities.

  11. Conscious Augmentation of Creative State Enhances "Real" Creativity in Open-Ended Analogical Reasoning.

    Adam B Weinberger

    Full Text Available Humans have an impressive ability to augment their creative state (i.e., to consciously try and succeed at thinking more creatively. Though this "thinking cap" phenomenon is commonly experienced, the range of its potential has not been fully explored by creativity research, which has often focused instead on creativity as a trait. A key question concerns the extent to which conscious augmentation of state creativity can improve creative reasoning. Although artistic creativity is also of great interest, it is creative reasoning that frequently leads to innovative advances in science and industry. Here, we studied state creativity in analogical reasoning, a form of relational reasoning that spans the conceptual divide between intelligence and creativity and is a core mechanism for creative innovation. Participants performed a novel Analogy Finding Task paradigm in which they sought valid analogical connections in a matrix of word-pairs. An explicit creativity cue elicited formation of substantially more creative analogical connections (measured via latent semantic analysis. Critically, the increase in creative analogy formation was not due to a generally more liberal criterion for analogy formation (that is, it appeared to reflect "real" creativity rather than divergence at the expense of appropriateness. The use of an online sample provided evidence that state creativity augmentation can be successfully elicited by remote cuing in an online environment. Analysis of an intelligence measure provided preliminary indication that the influential "threshold hypothesis," which has been proposed to characterize the relationship between intelligence and trait creativity, may be extensible to the new domain of state creativity.

    2015-08-01

    Citizens’ opinions are crucial for action on climate change, but are, owing to the complexity of the issue, diverse and potentially unformed. We contribute to the understanding of public views on climate change and to knowledge needed by decision-makers by using a new approach to analyse answers to the open survey question `what comes to mind when you hear the words `climate change’?’. We apply automated text analysis, specifically structural topic modelling, which induces distinct topics based on the relative frequencies of the words used in 2,115 responses. From these data, originating from the new, nationally representative Norwegian Citizen Panel, four distinct topics emerge: Weather/Ice, Future/Impact, Money/Consumption and Attribution. We find that Norwegians emphasize societal aspects of climate change more than do respondents in previous US and UK studies. Furthermore, variables that explain variation in closed questions, such as gender and education, yield different and surprising results when employed to explain variation in what respondents emphasize. Finally, the sharp distinction between scepticism and acceptance of conventional climate science, often seen in previous studies, blurs in many textual responses as scepticism frequently turns into ambivalence.

  6. Node Primitives: an open end-user programming platform for social robots

    OpenAIRE

    Coronado, Enrique; Mastrogiovanni, Fulvio; Venture, Gentiane

    2017-01-01

    With the expected adoption of robots able to seamlessly and intuitively interact with people in real-world scenarios, the need arises to provide non-technically-skilled users with easy-to-understand paradigms for customising robot behaviors. In this paper, we present an interaction design robot programming platform for enabling multidisciplinary social robot research and applications. This platform is referred to Node Primitives (NEP) and consists of two main parts. On the one hand, a ZeroMQ ...

  7. Using Agent-Based Modeling to Assess Liquidity Mismatch in Open-End Bond Funds

    Directory of Open Access Journals (Sweden)

    Donald J. Berndt

    2017-12-01

    Full Text Available In this paper, we introduce a small-scale heterogeneous agent-based model of the US corporate bond market. The model includes a realistic micro-grounded ecology of investors that trade a set of bonds through dealers. Using the model, we simulate market dynamics that emerge from agent behaviors in response to basic exogenous factors (such as interest rate shocks and the introduction of regulatory policies and constraints. A first experiment focuses on the liquidity transformation provided by mutual funds and investigates the conditions under which redemption-driven bond sales may trigger market instability. We simulate the effects of increasing mutual fund market shares in the presence of market-wide repricing of risk (in the form of a 100 basis point increase in the expected returns. The simulations highlight robust-yet-fragile aspects of the growing liquidity transformation provided by mutual funds, with an inflection point beyond which redemption-driven negative feedback loops trigger market instability.

  8. IDENTITY IN TRANSITIONAL CONTEXT: OPEN-ENDED LOCAL ARCHITECTURE IN SAUDI ARABIA

    Directory of Open Access Journals (Sweden)

    Mashary Al-Naim

    2008-07-01

    Full Text Available This paper attempts to analyze the experience of change in Saudi contemporary architecture with special emphasis on the ways that people have used to adopt new forms in their home environment. The aim is to understand the general reactions of people towards the change over time. Identity is a social system, and unless we view it from this perspective we cannot understand how people realize it in their home environment. In this sense, we are looking for the relationship between people and their architecture rather than explaining the reasons behind any changes identified.

  10. Cross-border mergers and minority protection
    An open-ended harmonization

    Directory of Open Access Journals (Sweden)

    Marieke Wyckaert

    2008-03-01

    Full Text Available Minority protection is an important, though difficult, issue in company law, and a subtle balance must be struck between the legitimate interests of the majority and minority shareholder(s. The rules on minority protection in the context of the Cross-border Mergers Directive, which was recently adopted and should have been transposed into Member States’ national law towards the end of 2007, are examined in this paper. The authors analyse how minority shareholders are protected within the scope of this Directive and how some of the Member States (such as Germany, Italy, Belgium and the Netherlands have transposed or will transpose some of these protective provisions. The different levels of minority protection (information rights, consultation rights, rights to challenge majority decisions and other specific rights are considered, as well as which types of shareholders can benefit from such protection, and why they should be afforded protection. With respect to the last question, the authors conclude that the change in corporate law encountered especially by the shareholders of the disappearing company seems to be the major rationale underlying the European legislator's decision to introduce minority protection (but not oblige Member States to do so. The authors submit that this reflects too narrow a vision on the need for minority protection because it ignores the fact that the change of the corporate form as a consequence of a merger is in itself sufficient rationale for protecting minority shareholders. It remains somewhat of a mystery as to why the European legislator, while confirming that a cross-border merger should be subject to the same rules as a national merger, has created one possible and very vague exception to that rule.

  16. Comment on ``Communicating Government Science''

    Science.gov (United States)

    Lins, Harry F.

    2006-05-01

    Soroosh Sorooshian's editorial in the 18 April issue of Eos (87(16) 2005) is a timely reminder of the need for unambiguous guidelines governing the interactions between government scientists and the media. His comments implicitly recognize the central role that science plays in a modern democratic society, which includes informing policy at the highest levels of government and educating the general public about the world we inhabit. Federal research scientists, who constitute approximately 15 percent of the AGU's U.S. membership, have a unique public responsibility. They would welcome a consistent policy for the review and approval of publications, oral presentations, and media communications. An example of the value and success that such a policy can have to both science and the nation is evident in the operations of the U.S. Geological Survey (USGS). For more than a century, the USGS has had clear policies and procedures for ensuring the communication of accurate, high-quality, and impartial scientific information. These policies and procedures are set forth in the USGS Manual under sections entitled ``Approval by the director for outside publication and oral presentation,'' ``Review of USGS publications and abstracts of oral presentations for policy-sensitive issues,'' and ``News release and media relations policy.'' These policies are available online at http:// www.usgs.gov/usgs-manual/500/500-9.html (.../500-8.html and .../500 5.html).

  19. Positive aspects of being a heterosexual ally to lesbian, gay, bisexual and transgender (LGBT) people.

    Rostosky, Sharon S; Black, Whitney W; Riggle, Ellen D B; Rosenkrantz, Dani

    2015-07-01

    Research on heterosexual allies has focused on heterosexual identity development models and pathways to ally activism. The positive aspects or positive experiences of identifying as an ally to lesbian, gay, bisexual, and transgender (LGBT) identified individuals and communities have received little attention. Using an online survey of participants recruited from LGBT ally related social media, we collected open-ended responses to a question about the positive aspects of self-identifying as a heterosexual ally. A final analytic sample of 292 self-identified male and female heterosexual adults (age 18-71, M = 33.47, SD = 13.32) provided responses that generated 8 themes. Positive aspects of being a heterosexual ally were: (a) increased knowledge and awareness, (b) upholding values of justice, (c) beneficial individual relationships, (d) community belonging, (e) educating others, (f) being a role model, (g) using social privilege, and (h) speaking out and taking a stand. The findings suggest that being a heterosexual ally is rewarding and may enhance individual well-being. These findings provide information that may contribute to effective ally development efforts.

  9. Online News Sites and Journalism 2.0: Reader Comments on Al Jazeera Arabic

    Directory of Open Access Journals (Sweden)

    Muhammad M. Abdul-Mageed

    2008-12-01

    Full Text Available The current paper investigates reader commenting on news sites as one facet of journalism 2.0. Specifically, the themes, frequency, and regional coverage of readers’ comments—and in general, their activity levels and distribution—are considered, with a goal to increase knowledge of convergent media and computer-mediated communication (CMC, as well as shed light on the interactivity strategies adopted by influential news producers. The corpus is collected from the Arabic news site of the controversial Middle East-based, bilingual network Al Jazeera. Reader commenting was found to be a regular occurrence on the site but distributed unevenly across stories. The stories focused mostly on themes related to military and political violence, politics, and foreign relations, and covered events related to the Arab world more than other regions. Also, patterns of commenting varied according to day of the week and position of the story on the web page. Overall, these findings suggest that citizen journalism—journalism is performed by lay persons—on Al Jazeera tends to be shaped by the coverage and layout of the news site. Moreover, citizen participation in online news sites such as Al Jazeera is still far from ideal, in that commenters are given neither the access nor the facilitation to use modalities other than written text. These limitations are critiqued in light of contemporary discourses about media convergence and journalism 2.0.

  10. A community of curious souls: an analysis of commenting behavior on TED talks videos.

    Tsou, Andrew; Thelwall, Mike; Mongeon, Philippe; Sugimoto, Cassidy R

    2014-01-01

    The TED (Technology, Entertainment, Design) Talks website hosts video recordings of various experts, celebrities, academics, and others who discuss their topics of expertise. Funded by advertising and members but provided free online, TED Talks have been viewed over a billion times and are a science communication phenomenon. Although the organization has been derided for its populist slant and emphasis on entertainment value, no previous research has assessed audience reactions in order to determine the degree to which presenter characteristics and platform affect the reception of a video. This article addresses this issue via a content analysis of comments left on both the TED website and the YouTube platform (on which TED Talks videos are also posted). It was found that commenters were more likely to discuss the characteristics of a presenter on YouTube, whereas commenters tended to engage with the talk content on the TED website. In addition, people tended to be more emotional when the speaker was a woman (by leaving comments that were either positive or negative). The results can inform future efforts to popularize science amongst the public, as well as to provide insights for those looking to disseminate information via Internet videos.

  17. Positive criminology in practice.

    Science.gov (United States)

    Ronel, Natti; Segev, Dana

    2014-11-01

    The discourse regarding offender rehabilitation has been criticized by various scholars who have claimed that reducing negative causes and managing risk will not automatically prompt positive human development and elements that are associated with desistance. Positive criminology is an innovative concept that challenges the common preoccupation with negative elements, by placing emphasis on human encounters and forces of inclusion that are experienced positively by target individuals and that can promote crime desistance. However, as the concept is relatively new, there are still no guiding principles for the practice of positive criminology that could direct research and the criminal justice system. This article attempts to fill that gap by providing principles that could be practiced by criminal justice personnel and examples of different interventions that reflect positive criminology. The article also provides ideological explanations for adopting the concept of positive criminology in practice. © The Author(s) 2013.

  20. Proposed standby gasoline rationing plan: public comments

    Energy Technology Data Exchange (ETDEWEB)

    1978-12-01

    Under the proposed plan, DOE would allocate ration rights (rights to purchase gasoline) to owners of registered vehicles. All vehicles in a given class would receive the same entitlement. Essential services would receive supplemental allotments of ration rights as pririty firms. Once every 3 months, ration checks would be mailed out to all vehicle registrants, allotting them a certain amount of ration rights. These checks would then be cashed at Coupon Issuance Points, where the bearer would receive ration coupons to be used at gasoline stations. Large users of gasoline could deposit their allotment checks in accounts at ration banks. Coupons or checks would be freely exchangeable in a white market. A certain percentage of the gasoline supply would be set aside in reserve for use in national emergencies. When the plan was published in the Federal Register, public comments were requested. DOE also solicited comments from private citizens, public interest groups, business and industry, state and local governments. A total of 1126 responses were reveived and these are analyzed in this paper. The second part of the report describes how the comments were classified, and gives a statistical breakdown of the major responses. The last section is a discussion and analysis of theissue raised by commenting agencies, firms, associations, and individuals. (MCW)
