Instructor Fluency Correlates with Students’ Ratings of Their Learning and Their Instructor in an Actual Course

The experience of ease or fluency that occurs when learners acquire information is often highly related to their metacognitive judgments of learning for that information. Laboratory-based research indicates that fluency can contribute to students’ overconfident judgments of learning and predictions of future test performance. Such research, however, typically involves artificial learning situations presented for brief periods of time and without a strong investment on the part of the learners. In actual courses, the most likely source of fluency may be instructor fluency: the experience of fluency that stems from content-independent attributes of the instructor and his or her presentation of the information. To examine whether this form of fluency relates to students’ judgments of learning in actual academic courses, we include a measure of instructor fluency in a survey completed by college students (n = 606) answering questions about their course instructors. Students’ content-independent perceptions of instructor fluency (e.g., volume; eye contact) are related to their judgments of learning for the course content, to their ratings of various qualities of the instructor and the course, and to their self-reported interest and motivation in the course. Importantly, these relationships maintain when we control for students’ final grades in the course and despite the fact that students make these ratings at a long temporal delay from the classroom experience. Therefore, much as occurs in the laboratory, students’ metacognitive judgments of their learning and ratings of instructor attributes are related to content independent qualities of their course instructors in actual semester-long courses.
Numerical study of the ocean circulation on the East China Sea shelf and a Kuroshio bottom branch northeast of Taiwan in summer

Using the Regional Ocean Model System, the ocean circulation on the East China Sea (ECS) shelf was examined by a fine-resolution model which was nested in a coarse-resolution Pacific Ocean model. The high-resolution simulation shows an accurate volume transport of 2.70 Sv (Sv = 10(6) m(3)s(-1)) through the Tsushima Strait, which is more consistent with the previous 5.5 year observation value (2.64 Sv) than former model results. For the Taiwan Strait it also shows a close volume transport (1.03 Sv) to a recent estimate (1.20 Sv). At the same time the model results reproduced almost all of the known circulation structure on the ECS shelf. In addition, the hindcast of 2009 shows a Kuroshio Bottom Branch Current to the northeast of Taiwan (KBBCNT). The KBBCNT is confirmed by the observational bottom high-salinity water (from 15 August to 2 September 2009) whose distribution is also reproduced by the model results. Tracer and particle experiments were carried out to elucidate the formation of the high-salinity water and the pathway of the KBBCNT. In light of the field observation and numerical experiments, a new pathway of the KBBCNT is proposed: bifurcated from the subsurface water of Kuroshio northeast of Taiwan, it upwells northwestward gradually from 300 to 60 m, then turns to northeast in the region around 27.5 degrees N, 122 degrees E, and finally reaches 31 degrees N off the mouth of the Changjiang River along similar to 60 m isobaths, forming the bottom saline water off the coast of Zhejiang province, China.

Development of Verbal Expressive Skills Management Programme (VESMP) for Patients with Brocas Aphasia

Introduction: Disorders of communication, including aphasia (mainly post stroke) caused by the left hemisphere brain damage, is a major community health issue. The prevalence of aphasia after stroke is 25% in Pakistan in which Broca’s aphasia is predominant in stroke patients who have anterior lesion in the frontal lobe of the left hemispheres. The verbal expressive skills management programme (VESMP) is the software which developed augmented management for patients to enhance verbal expressive skills for patients with severe Broca’s aphasia from different geographic areas. Moreover, the software increases the independencies which are not observed in other traditional techniques. This study is the pathway for maintaining and improving the functional life of patients. Objectives: The main objective was to develop the verbal expressive skills management programme (VESMP) to enhance verbal expressive skills of patients with severe Broca’s aphasia. Methodology: Initially a pilot study with eight cases is carried out. The nonprobability purposive sampling technique was used to recruit the patients with severe aphasia who received therapy through VESMP programme on their smart phones. It contains seven domains: spontaneous speech, comprehension, naming, reading, writing, imitation, and automated speech. The programme was developed in Urdu language and its content was selected from grade three Urdu Punjab text books. The program was then updated with the help of guidance and feedback received from five experts of the relevant field. The patients scoring is recorded for each domain on basis of correct responses. The study was conducted in YUSRA general hospital and Pakistan Railway Hospital, Rawalpindi. The study includes patients that are 40+ years old, and have three months of post stroke with diagnosis of chronic Broca’s Aphasias, patients with severe cognitive impairment were excluded from the study. The pre-and post score was recorded for each domain for the measurement of change. The treatment protocol for each patient lasts for 8 weeks that includes 4 VESMP sessions per week with each session being 30-45 minutes long. Data for each patient was analyzed based on their pre-and post-intervention scores. Results: The scores were computed in terms of mean and standard deviation. The pre-and post-scores of each patient compares separately through which remarkably improvement in all domains. The results also illustrate significant difference (p=0.05) between the preand post-scores on each domain of the programme and show the vital improvement in verbal expressive skills of patients with severe Broca’s aphasia. Conclusion: It is concluded from the results that the development of VESMP programme improved verbal expressive skills of patients with severe Broca’s aphasia.
Talent Management Philosophies and Practices in the Chinese Multinational Corporations: An Empirical Study

A legacy of a centrally planned economy with a strong traditional bound culture, coupled with the dynamism injected by the arrival of international multinational corporations (MNCs), and even the rise of Chinese MNCs has created strong demands for talent in all spheres of China’s economic life. As Chinese companies extend their global reach, they increasingly face the complexities of personnel acquisition, including severe shortages of domestic managerial talent, international brain drain of educated Chinese youth, and migration of managers from domestic Chinese companies to global MNCs. Against this background, the present study explores ways in which Chinese MNCs strategically integrate resources at the international level to attain global business success. The study finding indicated there is a crossvergence of talent management practices in Chinese MNCs, and such finding has potential to contribute to understanding how to overcome the identified barriers to the internationalisation process, especially in locating managerial talents.
Production Efficiency of Physicians in Outpatient Consultation of Cardiovascular Cases

Background: We evaluated the production efficiency of physicians in outpatient consultation using Data Envelopment Analysis (DEA) to verify the applicability of this method in health care field. Methods: Clinical accomplishment by outpatient consultation (number of complex cases) and economic contribution to health service income (fee claims) were defined as the contributions of physicians in medical institutions. We investigated consultations and fee claims of 963 outpatients (all aged: 72.9 ± 11.8 years, males aged: 72.0 ± 11.7 years / females aged: 74.0 ± 12.0 years, hypertension: 17.5% / angina: 13.1%) consulted by 15 physicians in a week at a medical institution specialized in cardiovascular disease. The physician’s fee claim per practice time was used as an index in production efficiency of each cardiovascular case. We determined production efficiency of physicians using both of total fee claim and number of complex cases per consultation time using DEA. Results: There was no statistically significant difference between main disease of outpatients in consultation time (p=0.28). We showed a significant increment of physicians fee claim (point per min) according to the patient condition aggravated from mild to moderate cases in severity (71.4 ± 2.4: p=0.004). The production efficiency also significantly increased from the first consultation to follow-up (71.6 ± 2.4: p=0.048). There was a large variation among the 15 physicians in the consultations, and 4 physicians (26% of all subjects) formed a group with the most favorable production efficiency according to DEA. Conclusion: We demonstrated evaluation of production efficiency of physicians using clinical and economic accomplishments. The production efficiency is significantly influenced by disease severity and consultation step. Our finding suggests that DEA may be applicable for evaluation of health care services.
Text Mining in Archaeology : Extracting Information from Archaeological Reports

Archaeologists generate large quantities of text, ranging from unpublished technical fieldwork reports (the ‘grey literature’) to synthetic journal articles. However, the indexing and analysis of these documents can be time consuming and lacks consistency when done by hand. It is also rarely integrated with the wider archaeological information domain, with bibliographic searches having to be undertaken independently of database queries, for example. Text mining offers a means of extracting information from large volumes of text, providing researchers with an easy way of locating relevant texts and also of identifying patterns in the literature. In recent years techniques of Natural Language Processing (NLP) and its subfield, Information Extraction (IE), have been adopted to allow researchers to find, compare and analyse relevant documents, and to link them to other types of data. This chapter introduces the underpinning mathematics and provides a short presentation of the algorithms and distance measures used, from the point of view of artificial intelligence and computational logic. It describes the different NLP schools of thought and compares the pros and cons of rule-based vs machine learning approaches to information extraction. The role of ontologies and named entity recognition will be discussed and the chapter demonstrates how IE can provide the basis for semantic annotation and how it contributes to the construction of a semantic web for archaeology. The authors have worked on a number of projects that have employed techniques from NLP and IE in Archaeology, including Archaeotools, STAR and STELLAR. The chapter describes the archaeological user needs requirement, drawing examples from several countries, and the authors present examples drawn from their own projects, and previous work by others, of how NLP and IE can contribute to addressing this need. The problems and challenges of employing text mining in the archaeological domain are discussed, as well as the potential benefits.
Queueing Systems with Synergistic Servers

We consider tandem lines with finite buffers and flexible, heterogeneous servers that are synergistic in that they work more effectively in teams than on their own. Our objective is to determine how the servers should be assigned dynamically to tasks in order to maximize the long-run average throughput. In particular, we investigate when it is better to take advantage of synergy among servers, rather than exploiting the servers’ special skills, to achieve the best possible system throughput. We show that when there is no trade-off between server synergy and servers’ special skills (because the servers are generalists who are equally skilled at all tasks), the optimal policy has servers working in teams of two or more at all times. Moreover, for Markovian systems with two stations and two servers, we provide a complete characterization of the optimal policy and show that, depending on how well the servers work together, the optimal policy either takes full advantage of servers’ special skills, or full advantage of server synergy (and hence there is no middle ground in this case). Finally, for a class of larger Markovian systems, we provide sufficient conditions that guarantee that the optimal policy should take full advantage of server synergy at all times. Subject classifications: production/scheduling: flexible manufacturing/line balancing; dynamic programming/optimal control: applications; queues: tandem.
Use of Various Chelates as Soil Extractants

Four chelating agents—DTPA, EDTA, AB-DTPA and six molarities of sodium gluconate (0.005M, 0.01M, 0.015M, 0.02M, 0.025M and 0.03M) were compared as extractants for Cu, Fe, Zn, Mn, Pb, Ni, Cr and Cd in 5 diverse soils collected at different locations surrounding Peshawar from 0-30cm depth. Soil samples were also analyzed for soil chemical properties. The data of chemical analysis showed that soil pH was alkaline in nature. Electrical conductivity values of soil samples showed that the samples were non saline. Organic matter was found deficient and medium in 40 and 40 % samples respectively. AB-DTPA was the most effective extractant for Cu, Fe, Mn, Pb, Ni, and Cr whereas EDTA was the most effective extractant for Cd and Zn. An increasing trend in extractability of the nutrient was observed with an increase in the molarities of sodium gluconate. Keywords : DTPA, EDTA, AB-DTPA, soil pH, Electrical conductivity, mineral nutrients
Staying Longer in Unemployment Registry in Russia: Lack of Education, Bad Luck or Something Else? 1

Using individual-level data on registered unemployed collected by the Federal Employment Service in Voronezh province of Russia (1996-2000), we test some basic hypothesis on the influence of individual attributes (gender and education, in particular), working history, the specifics of the regulatory framework, and regional labor market characteristics on the hazard ratios, and hence, on duration of unemployment. We get empirical support to gender and educational differentials in unemployment duration: women tend to stay longer in the pool, and there are gender asymmetries in the influence of employment history on unemployment duration; those with junior professional education have significantly higher exit rates from unemployment as compared with those with secondary general education, while secondary professional and university degrees do not help you leave unemployment. There appears to be a “premium” in terms of higher exit rate for males with experience at private enterprise, but not for females, while the configuration of the local labor market does matter for both: those living in municipalities with highly concentrated labor market tend to have longer unemployment spells.
Function projective synchronization for four scroll attractor by nonlinear control

This paper presents a function projective synchronization of two identical four scroll attractor, when the parameters of the drive system are known and fully unknown of the response system. Based on Lyapunov stability theory a control law is designed to make the states of two identical four scroll attractor asymptotically synchronized. This method is efficient and easy to implement. The numerical simulations are presented to show the effectiveness of the proposed schemes.
Application of neurocomputing in the parametric identification using dynamic responses of structural elements – selected problems

Some problems of neurocomputing in the dynamics of structures are presented: 1) damage detection using wave propagation, 2) updating of portal frames finite element models, 3) detection of the void and additional mass in cantilever plates, 4) neural network modelling of an ''artificial boundary condition''. The analysed problems are related to both data prepared by computational systems and that taken from experimental evidence.
Dierences in Beliefs and Currency Options Markets

This paper investigates how heterogeneous beliefs of professional investors impacts on the currency options market. Using a unique data set with detailed information on the foreign-exchange forecasts of about 50 market participants over more than ten years, we construct an empirical proxy for dif- ferences in beliefs. We show that our proxy has a statistically and economically strong eect on the implied volatility of currency options, on the shape of the implied volatility smile, on the volatility risk-premia, and on future currency returns. We document that the volatility of macroeconomic fundamentals explains only a limited part of the dierence in beliefs dynamics. Furthermore, our …ndings cannot be explained by overcon…dence about priors or about a private signal. Our evi- dence demonstrates that a process largely unrelated to current macroeconomic fundamentals can have important asset pricing implications.
Estimating aid-growth equations: the case of Pacific island countries

The seminal and controversial work of Burnside and Dollar (2000) has been the basis for many subsequent empirical works on the growth effects of overseas development aid. This paper argues that the specifications used in these works are not consistent with the data and techniques used. We propose a modified production function in which total factor productivity depends on time as well as the aid ratio. Our empirical results show that the effect of aid on the steady state growth rate is insignificant in the selected Pacific Island countries. These countries are of interest because they receive the largest aid in per capita terms.
Early evolution of the compressible mixing layer issued from two turbulent streams

Direct numerical simulation of the spatially developing mixing layer issuing from two turbulent streams past a splitter plate is carried out under mild compressibility conditions. The study mainly focuses on the early evolution of the mixing region, where transition occurs from a wake-like to a canonical mixing-layer-like behaviour, corresponding to the filling-up of the initial momentum deficit. The mixing layer is found to initially grow faster than linearly, and then at a sub-linear rate further downstream. The Reynolds stress components are in close agreement with reference experiments and follow a continued slow decay till the end of the computational domain. These observations are suggestive of the occurrence of incomplete similarity in the developing turbulent mixing layer. Coherent eddies are found to form in the close proximity of the splitter plate trailing edge, that are mainly organized in bands, initially skewed and then parallel to the spanwise direction. Dynamic mode decomposition is used to educe the dynamically relevant features, and it is found to be capable of singling out the coherent eddies responsible for mixing layer development.
Attentional Demands of Locomotor and Balance Tasks in Individuals Aging with and without a Stroke

Background: The purpose of this study was to examine the cognitive-motor interference pattern while concurrently performing a higher cognitive task with three dynamic postural tasks – limits of stability (intentional balance), compensatory stepping during (reactive balance -RB) and walking tasks across younger adults (YA), older adults (OA) and older chronic stroke survivors. Methods: Thirty-six individuals in each group performed either of the three postural tasks – forward limits of stability (LOS, intentional balance), forward compensatory stepping (reactive balance - RB) and walking task (gait) with (dual-task) and without (single-task) performing a serial subtraction (SS) task. The SS tasks was also performed in isolation. Maximum center of pressure excursion (MXE) for LOS, center of mass position relative to base of support at step touchdown for RB, gait velocity and number of correct responses for SS task were measured. Motor and cognitive costs were calculated. Results: The healthy adults showed higher motor cost for more dynamic gait and RB tasks compared with the LOS task however, motor costs were similar for all the tasks in the stroke group. Although the motor cost for OA and stroke groups were more than YAs for all postural tasks, motor cost was significantly greater in stroke group than OA group only for the LOS task. Conclusion: The attentional demands are higher for postural task that are biomechanically unstable in healthy adults. Chronic stroke survivors show disproportionate ability to divide attention seen by higher motor cost during LOS task. Nevertheless, in chronic phase of recovery, stroke survivors may regain some dual-task function displaying similar strategies as healthy counterparts.
Comparison between femtosecond laser and fusion-arc inscribed long period gratings in photonic crystal fibre

The use of high intensity femtosecond laser sources for inscribing fibre gratings has attained significant interest. The principal advantage of high-energy pulses is their ability for grating inscription in any material type without preprocessing or special core doping. In the field of fibre optical sensing LPGs written in photonic crystal fibre have a distinct advantage of low temperature sensitivity over gratings written in conventional fibre and thus minimal temperature cross-sensitivity. Previous studies have indicated that LPGs written by a point-by-point inscription scheme using a low repetition femtosecond laser exhibit post-fabrication evolution leading to temporal instabilities at room temperatures with respect to spectral location, strength and birefringence of the attenuation bands. These spectral instabilities of LPGs are studied in photonic crystal fibres (endlessly single mode microstructure fibre) to moderately high temperatures 100°C to 200°C and their performance compared to fusion-arc fabricated LPG. Initial results suggest that the fusion-arc fabricated LPG demonstrate less spectral instability for a given constant and moderate temperature, and are similar to the results obtained when inscribed in a standard single mode fibre.
