TORSIONALLY COUPLED DYNAMIC ANALYSIS OF ASYMMETRIC OFFSHORE PLATFORM SUBJECTED TO WAVE AND EARTHQUAKE LOADINGS

Mass eccentricity and stiffness eccentricity are two key forms of asymmetric structures.Based on the general dynamic equation of one-storey asymmetric offshore platform subjected to wave and earthquake loadings, the vibration equation considering different eccentricity forms is deduced in this paper.At different water depths, the performances of asymmetric platforms subjected to earthquake load, wave load, or simultaneously both, are numerically analyzed.The torsionally coupled effects are studied considering the variation in eccentricity form, eccentric ratio and target component's location.In addition, the influence of environmental action intensity on torsionally coupled effect is analyzed.The numerical results show that eccentricity form, eccentric ratio and target position have non-negligible influence on torsionally coupled effects.Furthermore, the influences of combined environmental actions are different for asymmetric platforms with different periods or in different foundation conditions.

An Analysis of Peer Assessment through Many Facet Rasch Model

This study analyses peer assessment through many facet Rasch model (MFRM). The research was performed with 91 undergraduate students and with lecturer teaching the course. The research data were collected with holistic rubric employed by 6 peers and the lecturer in rating the projects prepared by 85 students taking the course. This study analyses raters, measurements for students who are rated, criteria used in rating and extent to which rubrics fulfil their function. Moreover, it also investigates effects of peers’ levels of achievement on the process. In consequence, it was found that raters differed in the levels of strictness and generosity in rating, and that students were distinguished adequately in terms of the property measured. Besides, a very high level of reliability value was estimated in relation to the criteria in the study.  This was interpreted as that they functioned in a reliable way in distinguishing between students’ performances. It was found in the analyses of achievement levels of peers taking part in peer assessment that ratings made by students with high levels of achievement differed significantly from those made by students with medium or low level of achievement. Finally, the views about peer assessment were generally positive.  peer assessment, many facet Rasch model, levels of peer achievement, rubric

Discussing mentorship: An ongoing study for the development of a mentorship program in Saskatchewan.

To identify the essential components of a mentorship program as the first step in the ongoing development of a mentorship program for primary care physicians.



Mixed-methods study.



Saskatchewan.



Forty-nine of 170 physicians responded positively to a letter of invitation. Of these, 25 physicians were purposively sampled based on location, sex, and experience. Fourteen participants practised in urban areas and 11 in rural settings; 11 were men and 14 were women; and 10 were junior physicians and 15 were senior. Junior physicians were defined as those who had graduated from medical school after 1995, and senior physicians were those who had graduated before 1980.



This study employed qualitative, in-depth, semistructured interviews. Interview questions, based on an environmental scan, were developed then pilot-tested with a family physician. Interviews lasted approximately 60 minutes and were audiotaped. Digital audio files were transcribed verbatim and analyzed thematically.



Family physicians described positive and negative aspects of mentoring, or having a lack of experience with mentoring. They also outlined key components of a potential mentorship program: matching mentees with mentors; integrating formal and informal mentorship; and the evaluation process of the mentorship relationship and program.



Based on the feedback from family physicians, mentorship is viewed as an important and meaningful program of action that regional health stakeholders and medical educators in Saskatchewan could implement. A pilot test of a mentorship program model will be the culmination of this study. Further research will be undertaken to evaluate the model once it is implemented. This will have important implications for establishing a national mentorship program for family physicians across the country.

CONTROLLED IN VITRO ENVIRONMENT FOR STAGE II MiCROPROPAGATION OF BUDDLEIA ALTERNIFOLIA (BUTTERFLY BUSH)

Optimal light, sucrose, and CO2 levels were determined for Stage II micropropagation of Buddleia alternifolia (Butterfly Bush). Five levels each of light (50, 75, 100, 125, 150 ixmol m-2s-l PPF), of sucrose (0, 1, 2, 3, and 4%), and of force-ventilated CO2 (0, 350, 600, 900, 1200 ppm) were compared through one-way factorial experiments. Three levels of each factor were then selected for a 3x3x4 factorial experiment of the same culture. Free-ventilated CO2 of 350 ppm, serving as control, constituted the fourth level of CO2. The results showed that the observed optimum points were 2% sucrose, 125 |xmol m-2s-l PPF, and 600 ppm force-ventilated CO2. Based on the lack of interactive effects between the factors, the general absence of statistical differences between the levels within each optimum factor range, and considerations of economic benefits, the preferred factor levels were chosen to be 3% sucrose, 350 ppm free-ventilated CO2, and 75 |imol m-2s-i PPF. The study also revealed that elevated in vitro light and CO2 levels, in the absence of sucrose, did not promote the growth of the culture.

Algorithm Fusing Gabor Feature Based on Random Dot Product Graph

In order to improve face recognition accuracy by using random graph theory,this paper presents a algorithm fusing Gabor feature based on random dot product graph. First use Gabor filter to extract Gabor feature from the training set. In order to reduce data redundancy,these features require some pre-treatment. Then access node assignment by reconstructing the training set of face images with random graph. According to the cosine of the assignment vector angle and their category information,calculated penalty value for each node. The identification image is projected to the subspaces which is reconstructed by the random dot product graph,classified based on the nearest neighbor node's penalty value. Experimentation on the ORL face image database indicate the effectiveness of the algorithm.

Autobiography of Edward R. Christophersen

presentations and publications have paved the way for other psychologists to contribute to the care of pediatric patients in medical settings, and to children’s health and safety in daily life as well. With one foot firmly planted in pediatric medicine and the other in child and adolescent psychology, his outstanding record is hard to match. Few psychologists have done as much as Dr. Christophersen to facilitate the acceptance and incorporation of behavioral strategies into the work of our pediatric colleagues. Beyond these professionally-oriented contributions, we also note Dr. Christophersen’s tireless work in disseminating valid, empiricallybased information and guidelines on parenting behavior, both to parents and to the general public.

The influence of microwave pulse repetition frequency on the thermal burnout effect of a PIN diode limiting-amplifying system

This paper analyzes the influence of the microwave pulse repetition frequency on the thermal burnout effect of a PIN diode limiting-amplifying system. Based on the study of the single-shot microwave pulse thermal burnout effect and by introducing a new assumption that the heat dissipation of the electric field energy and the nonequilibrium carrier energy during the microwave pulse intervals can be neglected, the theoretical thermal burnout model in our previous study is extended to be suitable for repetitive microwave pulses. The theoretical relationship among the pulse number, the pulse repetition frequency, the pulse width and the thermal burnout power threshold is obtained by theoretical derivation. Because the assumptions are introduced, the theoretical relationship requires that both the whole length of a repetitive microwave pulse and the pulse width in a cycle of a repetitive microwave pulse should be between 10 ns and 10 μs. The results obtained by the theoretical relationship are in good agreement with the simulation results obtained by our self-designed device-circuit joint simulator, which verifies the correctness of the theoretical analyses, modeling and derivation. By fitting at least two sets of simulation or experimental data, the theoretical relationship can be used to predict the thermal burnout power thresholds of PIN diode limiting-amplifying systems under microwave pulse injections with different pulse parameters. It can greatly reduce the simulation or experimental costs and could be helpful for the design of a radio frequency receiver.

To Reconstruct the Poeticized Pedagogy

"Poetization" is a phenomenon and trend deserved attention of contemporary humanities study.In order to get out of the trap from scientism and integrate with life world and lives,humanities like philosophy try to combining literature and poetics,with the help of poetic language and poetic realm.In history,pedagogy has a poeticized body,which fades rapidly with accelerating scientific steps of modern pedagogy.To reconstruct the poeticized pedagogy is a turn of the contemporary pedagogy in linguistics.It could promote the revolution of pedagogical language expression and the epistemology change,making it closer to education life world.And also,the poeticized pedagogy can lead education to shake off instrumentalism values gradually,heading for an ideal poetic condition.

A case study of stakeholder perspective and experience with wild American ginseng (Panax quinquefolius) conservation efforts in Pennsylvania, U.S.A.: limitations to a CITES driven, top-down regulatory approach

Following its inclusion in Appendix II of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the harvest, sale and trade of wild ginseng (Panax quinquefolius) for international commerce has been restricted by law in Pennsylvania since the late 1980s. Since then, exports from the state have declined driving the need to better understand the impact of CITES listing and related state and federal laws. Between 2004 and 2010, we conducted a mixed-methods study in Pennsylvania of stakeholder perspectives on state and federal government conservation efforts and experiences relating to enforcement of harvest and trade restrictions. Results from a survey, key informant interviews, and facilitated group discussions indicate widespread support for ginseng conservation efforts but, not with the CITES driven, top-down regulatory approach. It was widely asserted that ginseng stewardship has been, and will continue to be, governed by personal experience, family teachings, and industry norms and not CITES driven restrictions per se. Moreover, study participants were unable to cite instances where prosecution for ginseng-related “crimes” had occurred within their networks and most believed laws are an ineffective deterrent to “bad behavior.” This emic is externally validated by the fact that agency enforcement is constrained by limited personnel and jurisdictional boundaries, not least of which is an inability to enforce on private lands in the state. These findings suggest that a CITES driven regulatory approach has limitations in actually conserving wild ginseng in Pennsylvania, and suggests that this approach should be complemented by stakeholder supported “bottom-up” partnerships involving greater stakeholder participation, such as government-sponsored or supported ginseng planting programs to counter over-exploitation by collectors and/or extirpation resulting from habitat loss.

Judging by color in the early history of geology and paleontology

This paper presents an overview on some significant historical sources, particularly from 17th to 18th century Italian scientific literature, in order to understand how color was used as one of the ‘external’ features for identifying rock formations, also including fossils, regarded as having formed in different times by different causes or events. The reference to color was also considered the main feature used for lithostratigraphical purposes within the so called ‘classifications’ of mountains in the second half of the 18th century. Later geologists and mineralogists involved in the early development of stratigraphy referred to color when a rock formation or specimen appeared to be less distinguishable by other main characters (for example chemical and morphological features).

Research on multi-parameter characteristics of a PCF sensor modified by GO composite films.

We propose a photonic crystal fiber (PCF) sensor based on graphene oxide (GO) composite film modification to simultaneously measure the multi-parameter sensing characteristics of humidity, temperature, and glucose concentration. The GO-polyvinyl alcohol (PVA) composite film is used to measure the humidity-sensing characteristics of the sensor, and the glucose oxidase composite film is used to measure the sensing characteristics of the glucose concentration, respectively. Experiment results show that the sensitivities of the temperature of the GO-PVA coating structure are 0.037 nm/°C, 0.047 nm/°C, and 0.031 nm/°C; the sensitivities of humidity are 0.059 nm/%RH, 0.121 nm/%RH, and 0.047 nm/%RH; and the sensitivities of the glucose concentration of the GO-GOD coating structure are 0.028 nm/(g/L), 0.049 nm/(g/L), and 0.010 nm/(g/L) for three interference dips, respectively. The structure is simple to manufacture and can be used as a sensor for detecting multiple parameters. It can be widely used in biomedicine, environmental monitoring, and other fields.

Differences in functional connectivity profiles as a predictor of response to anterior thalamic nucleus deep brain stimulation for epilepsy: a hypothesis for the mechanism of action and a potential biomarker for outcomes.

Deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) is a promising therapy for refractory epilepsy. Unfortunately, the variability in outcomes from ANT DBS is not fully understood. In this pilot study, the authors assess potential differences in functional connectivity related to the volume of tissue activated (VTA) in ANT DBS responders and nonresponders as a means for better understanding the mechanism of action and potentially improving DBS targeting.  This retrospective analysis consisted of 6 patients who underwent ANT DBS for refractory epilepsy. Patients were classified as responders (n = 3) if their seizure frequency decreased by at least 50%. The DBS electrodes were localized postoperatively and VTAs were computationally generated based on DBS programming settings. VTAs were used as seed points for resting-state functional MRI connectivity analysis performed using a control dataset. Differences in cortical connectivity to the VTA were assessed between the responder and nonresponder groups.  The ANT DBS responders showed greater positive connectivity with the default mode network compared to nonresponders, including the posterior cingulate cortex, medial prefrontal cortex, inferior parietal lobule, and precuneus. Interestingly, there was also a consistent anticorrelation with the hippocampus seen in responders that was not present in nonresponders.  Based on their pilot study, the authors observed that successful ANT DBS in patients with epilepsy produces increased connectivity in the default mode network, which the authors hypothesize increases the threshold for seizure propagation. Additionally, an inhibitory effect on the hippocampus mediated through increased hippocampal γ-aminobutyric acid (GABA) concentration may contribute to seizure suppression. Future studies are planned to confirm these findings.

New World News, Ancient Echoes: A Cortés Letter and a Vernacular Livy for a New King and His Wary Subjects (1520–23)*

Empire building converges with print innovations in the rare Zaragoza edition (1523) of the landmark “Second Letter from Mexico” of Hernán Cortés. The Aragonese print shop owned by German immigrant George Coçi advertised what, to its first interpreters, was stunning news from a still mysterious place overseas with woodblocks drawn from their 1520 edition of Livy's History of Rome. An examination of the political, social, and editorial contexts that informed these two books addressed to Charles V casts light on concerns about how the new Spanish king would communicate with his subjects in an age of imperial expansion.

Self-organizing map algorithm and distortion measure

We study the statistical meaning of the minimization of distortion measure and the relation between the equilibrium points of the SOM algorithm and the minima of the distortion measure. If we assume that the observations and the map lie in a compact Euclidean space, we prove the strong consistency of the map which almost minimizes the empirical distortion. Moreover, after calculating the derivatives of the theoretical distortion measure, we show that the points minimizing this measure and the equilibria of the Kohonen map do not match in general. We illustrate, with a simple example, how this occurs.

Effect of 1-MCP treatment on the quality of broccolis in cold storage

This paper was conducted to investigated the effect of different concentrations(1.5,2.5 μL/L) of 1-MCP on the quality of broccolis during 0 ℃ storage conditions.The physical and chemical indexes of broccolis were detected every 10 days.The results showed that:after treatment used 1-MCP,broccoli's soluble solids,Vc and chlorophyll content decreased less than ordinary -MCP inhibited the increase of respiratory intensity,increased peroxidase(POD),superoxide dismutase(SOD) activities and slowed down polyphenol oxidase(PPO) activity.Additionally,treatment of 1-MCP also decreased the MDA content and cell membrane permeability,so delayed ripening of broccoli.1-MCP treatment could delay ripening of broccoli,but 2.5 μL/L 1-MCP treatment is better than 1.5 μL/L treatment.Therefore,the storage effect of broccolis with 1-MCP treatment is superior to that of with only ordinary -MCP still played normal function at low temperature.

Global predictability of temperature extremes

Extreme temperatures are one of the leading causes of death and disease in both developed and developing countries, and heat extremes are projected to rise in many regions. To reduce risk, heatwave plans and cold weather plans have been effectively implemented around the world. However, much of the world’s population is not yet protected by such systems, including many data-scarce but also highly vulnerable regions. In this study, we assess at a global level where such systems have the potential to be effective at reducing risk from temperature extremes, characterizing (1) long-term average occurrence of heatwaves and coldwaves, (2) seasonality of these extremes, and (3) short-term predictability of these extreme events three to ten days in advance. Using both the NOAA and ECMWF weather forecast models, we develop global maps indicating a first approximation of the locations that are likely to benefit from the development of seasonal preparedness plans and/or short-term early warning systems for extreme temperature. The extratropics generally show both short-term skill as well as strong seasonality; in the tropics, most locations do also demonstrate one or both. In fact, almost 5 billion people live in regions that have seasonality and predictability of heatwaves and/or coldwaves. Climate adaptation investments in these regions can take advantage of seasonality and predictability to reduce risks to vulnerable populations.

Responding on concurrent-chains schedules in open and closed economies.

Pigeons' key pecks were reinforced according to concurrent-chains schedules of reinforcement. The programmed average time from the onset of the initial links to a terminal link entry was held constant across conditions while the value of variable-interval schedules in the terminal links was varied. Performance was assessed under two economic conditions: (a) an open economy in which session duration was limited to 1 hr and subjects were maintained at 80% of their free-feeding body weights with postsession food when necessary; and (b) a closed economy in which sessions were 23.5 hr long and no deprivation regimen was in effect. In all cases, the relative rate of responding in the initial links matched the reduction in overall delay to primary reinforcement correlated with entry into one terminal link relative to the reduction in delay correlated with entry into the other terminal link. Although the sum of responses made in the initial links and terminal links was found to increase, then decrease, as the rate of food presentation decreased in the closed economy, there was no consistent effect of overall rate of food presentation on total responding in the open economy. The choice data suggest that relative delay reduction predicts choice accurately, regardless of economic context.

Bifurcation analysis of the fully symmetric language dynamical equation.

In this paper, I study a continuous dynamical system that describes language acquisition and communication in a group of individuals. Children inherit from their parents a mechanism to learn their language. This mechanism is constrained by a universal grammar which specifies a restricted set of candidate languages. Language acquisition is not error-free. Children may or may not succeed in acquiring exactly the language of their parents. Individuals talk to each other, and successful communication contributes to biological (or cultural) fitness. I provide a full bifurcation analysis of the case where the parameters are chosen to yield a highly symmetric dynamical system. Populations approach either an incoherent steady state, where many different candidate languages are represented in the population, or a coherent steady state, where the majority of the population speaks a single language. The main result of the paper is a description of how learning reliability affects the stability of these two kinds of equilibria. I rigorously find all fixed points, determine their stabilities, and prove that all populations tend to some fixed point. I also demonstrate that the fixed point representing an incoherent steady state becomes unstable in an S (n)-symmetric transcritical bifurcation as learning becomes more reliable.
