Effects Of Feedback

The effects of feedback, prior judging experience and the level of the performance being judged on individual and group ratings of the performances were determined. 36 experienced and 36 inexperienced gymnastic judges viewed a film containing 20 gymnastic performances of low, moderate and high caliber under conditions of complete, partial, and no feedback of information as to the ratings of the other judges in their respective groups. On the basis of conformity theory it was hypothesized that groups rating performances in an open system are more reliable and accurate in their ratings than are groups operating in partial or no-feedback conditions. Further, this tendency was hypothesized to become manifest more if performances are of low caliber as opposed to moderate or high caliber and if the observers are experienced at rating performances as opposed to inexperienced. While the data supported these hypotheses, only partial support was achieved for the hypothesis that intraindividual variability will be greatest among no-feedback and inexperienced groups. It was found that inexperienced judges were individually more variable in their ratings than experienced judges and that more intraindividual variability was displayed among ratings of low-level performances. Judges' ratings were compared to absolute criterion scores derived by a group of experts through various film analysis techniques.

Workflow management promises a new solution to an age-old problem: controlling, monitoring, optimizing and supporting business processes. What is new about workflow management is the explicit representation of the business process logic which allows for computerized support. This paper discusses the use of Petri nets in the context of workflow management. Petri nets are an established tool for modeling and analyzing processes. On the one hand, Petri nets can be used as a design language for the specification of complex workflows. On the other hand, Petri net theory provides for powerful analysis techniques which can be used to verify the correctness of workflow procedures. This paper introduces workflow management as an application domain for Petri nets, presents state-of-the-art results with respect to the verification of workflows, and highlights some Petri-net-based workflow tools.

The text attempts to analyse the GDR Ministry of State Security’s offensive operations using the instruments of radio-electronic intelligence against the PPR in 1981. The situation in Poland, the emergence of Solidarność and possible, uncontrolled spreading of a wave of democratisation onto the East Germany’s territory as well, drove the leaders of the latter state to undertake actions aimed at ensuring it access to information on the on-going situation in the PRP. Apart from the data obtained officially, they also intended to resort to independent methods for its acquisition, most of all by employing the secret services. The author focuses on just one aspects of such operations, that is, radio-electronic intelligence. Apart from describing the structure and the working methods of the MfS’ III Directorate responsible for this type of reconnaissance, he presents the guidelines received by this organisation, its modus operandi and forms of work both on the territory of the GDR and the PPR, as well as on that of the other states. He also points to the effects and all the problems resulting from implementing intelligence operations, including those in the context of official co-operation between the secret services of the PPR and GDR. According to the author, the manner of carrying out offensive MfS operations by radio-electronic intelligence allows for a certain scepticism with regard to the thesis that the GDR services had unlimited opportunities to work in Poland. Based on the available archive sources, the observation that the MfS found it difficult to process and apply information obtained as a result of the services’ operations, is warranted. The shortage of competent staff can be clearly seen and not all the available technical instruments could perform their role. What was also important was the lack of understanding at the MfS of the different philosophy of life in the PPR, which determined the reception of its image obtained from the monitoring in place. Moreover, archive searches provide circumstantial evidence indicating that the Polish counter-intelligence was aware of what type of operations were being carried out by the GDR against Poland. The need for co-operation between the MfS and the MSW in the context of the radio-electronic intelligence against other states, as well as the awareness of the risk related to the possible discovery of illegal radio-electronic operations, led to their closing down. This failed, however, to change the belief that the fundamental operating principles of the secret services are to distrust one’s partners and to protect one’s own interests.

The Relationship

This study focuses on particles To and Ni as case particles that function to express the relationship between nouns and predicates in a sentence focusing on the comparative analysis of the two case particles. Based on Tsujimura's opinion, it can be said that in Japanese, case particles are part of a phrase. Case particle is related to the function of the words in the sentence. The method used to analyze the data is Agih method (distributional method). Advanced analysis techniques with substitution techniques were applied in this study. This technique is used to study a case particle in the Japanese sentence structure. This research produces several things that are expected to be helpful to readers. To and Ni case particles can replace each other for the context of sentences that have the following meanings: Pairs Meaning, Translative Meaning, Accusative Meaning, and Ablative Meaning. But on the other hand, To and Ni as case particles can not substitution each other. Especially sentences with the following meanings:  accusative meaning, commitative meaning, partner meaning, citation meaning, alatif meaning, purpose meaning, time markers meaning, diathesis on passive sentences, diathesis on causative sentences, dative meaning, and locative meaning.

In this work, we focus on the application of text mining and sentiment analysis techniques for analyzing Tunisian users' statuses updates on Facebook. We aim to extract useful information, about their sentiment and behavior, especially during the “Arabic spring” era. To achieve this task, we describe a method for sentiment analysis using Support Vector Machine and Naïve Bayes algorithms, and applying a combination of more than two features. The output of this work consists, on one hand, on the construction of a sentiment lexicon based on the Emoticons and Acronyms' lexicons that we developed based on the extracted statuses updates; and on the other hand, it consists on the realization of detailed comparative experiments between the above algorithms by creating a training model for sentiment classification.

The Bonfils and Levitan FPS™ scopes are rigid fibreoptic stylets that may assist routine or difficult intubation. This study compared the effectiveness of each in patients with predicted normal airways when used by specialist anaesthetists with no prior experience using optical stylets. Twelve anaesthetists and 324 elective surgical patients participated. Six anaesthetists were randomised to first intubate 20 patients with the Levitan scope (Phase 1) followed by a further seven patients with the Bonfils scope (Phase 2). The other six participating anaesthetists undertook their first 20 intubations with the Bonfils (Phase 1), followed by seven intubations with the Levitan (Phase 2). Outcomes recorded were success rate, total time to intubation, number of attempts, ease of intubation score and incidence of complications. Overall failure rates were similar for the two scopes with 5.6% of patients not intubated after three attempts. Median total times to intubation were similar for the Levitan (44 seconds) and Bonfils (36 seconds) (P=0.11). Participants using the Bonfils in Phase 1 had significantly higher chance of success on first attempt (73%) compared to Levitan users during Phase 1 (57%) (P=0.008). These differences were not significant in the second phase and ease of intubation scores were similar for both scopes (P=0.9). This study showed the two scopes were comparable but the high failure rate amongst novice users demonstrated the importance of familiarity and skill development prior to their introduction to a difficult airway cart.

Three groups of rats were each given 14 days of lever-press training under different conditions. One group was allowed to press only on a FR3 schedule, a second only on a CRF schedule, and a third received alternate-day training on CRF and FR3 schedules. Following training, 4 days of choice tests were given during which animals were allowed to choose between the two schedules of responding. Rats trained on the FR3 schedule both preferred to respond and obtained more rewards on that schedule, while rats in the other 2 groups preferred the CRF schedules. Results indicated that the degree of rats' preference for effortful responding is a function of the conditions of prior training.

Low Computational Cost

Analysis techniques and numerical formulations are available in a variety for mooring and riser designers. They are applied in the different stages of the design processes of floating production systems (FPS) by taking advantage of both the accuracy of results and the computational costs. In early design stages, the low computational cost is more valued with the aim of obtaining fast results and taking decisions. So in these stages it is common to use uncoupled analysis. On the other hand, in more advanced design stages, the accuracy of results is more valued, for which the use of coupled analysis is adequate. However, it can lead to excessive computing times. To overcome such high computational costs, new formulations have been proposed with the aim of obtaining results similar to a coupled analysis, but with low computational costs. One of these formulations is referred as the semi-coupled scheme (S-C). Its main characteristic is that it combines the advantages of uncoupled and coupled analysis techniques. In this way, analyses can be performed with very fast execution times and results are superior to those obtained by the classical uncoupled analysis. This work presents an evaluation of the S-C scheme. The evaluation is made by comparing their results with the results of coupled analyses. Both type of analysis were applied in a representative deep water platform. The results show that the S-C scheme have the potentially to provide results with appropriate precision with very low computational times. In this way, the S-C scheme represents an attractive procedure to be applied in early and intermediate stages of the design process of FPS.

Shift Change

Two freshman psychology classes were presented a series of factual statements and asked to respond either true or false both individually and collectively to determine the importance of individual performance preceding group performance and vice versa in terms of shift (change of an answer given to a statement in one situation from an answer previously given to the same statement in another situation), the influence on accuracy of one situation preceding the other and the amount of shift observed in students with high grades and those with low grades. The data indicated that students at the extreme lower grade level (quartile IV) tended to shift more than students at the extreme upper level (quartile I), but no clear-cut differentiation appeared in central areas (quartiles II and III). No significant difference in shift occurred when group performance preceded individual performance or vice versa. Group performance preceding individual performance did prove to have a beneficial influence upon the individual's performance in that Ss conform somewhat to the performance of the group. The accuracy of the group performance was superior to that of the individuals.

The purpose of this experiment was to compare the learning performance on a discrete second order control task between an experienced group of subjects, who had generated both accurate and inaccurate internal models through prior experience, to a group of subjects who had little prior experience and no model of the system dynamics. The 48 subjects were divided into six groups of eight subjects each. Three of the groups, the experienced groups, had previous training in a continuous control task and the other three groups, the no experience groups, had only a few trials on the continuous control task. The results showed that all three experienced groups learned the new discrete task faster than the no experience groups; the no experience groups actually got slightly worse with practice. It was concluded that an internal model, even an inaccurate one, provides a reference for subjects which can be used to analyze and improve their performance.
