Based on the common credit evaluation indexes system of the sellers for C2C, a fuzzy evaluating model is constructed based on Larsen criterion and the related algorithm is designed to evaluate the sellers. In this model, the indexes values are defined in continuous intervals and the internal relation between the overall evaluation and the sub-indexes is fully considered. So the credit characterization is close to the nature of the trading practices. Since the effect of the subjective factors on credit rating is efficiently eliminated in the calculation scheme, the credit grade got by the fuzzy algorithm is more reliable than the ones obtained by traditional methods. Finally, a numerical experiment is given to verify the effectiveness of the method.

THE CONTRACT OF PARTNERSHIP AS A BASE OF IN SOLIDUM LIABILITY IN ROMAN LAWSummary In the modern civil law joint and several liability of partners in a partnership is a rule rather than an exception. According to the common opinion this concept did not originate in the Roman law but was first invented in the medieval times by glossators and commentators. The Roman partnership created only a private relation between partners (who, due to a conclusion of that contract were reciprocally obliged to act together in accordance with a good faith in order to conduct common business and to divide profits and bear losses in proportion to their respective shares) and its conclusion did not affect their liability against third parties. The partners had no right to bind themselves contractually to any third parties, unless they all acted jointly (in this case, however, their joint representation was derived from their expressed declarations and not the existence of a contract o f partnership). Thus, any commitment made by an individual partner, even if made within the scope of a partnership having obtained other partners’ consent, was treated as a personal debt of this partner and the remaining partners were not liable against his contractor. Then, of course, the partner who made a commitment (acting within the partnership’s business) could claim a part of what he had paid to a third party from other partners in proportion to their respective shares in the common enterprise.Such a solution was necessary because of the purely consensual character o f the Roman partnership and the lack of any formal procedure of its conclusion and dissolution. The existence of that contract could not affect the model of the external liability of partners, because it would be too risky for third parties, which had no possibility to make sure if a contract of partnership between some persons had been actually concluded or not. Thus, the role of a contract of partnership in the Roman law was only limited to determine a mutual liability o f partners, to specify their respective rights and obligations and to define the scope of their liability against other partners.There are only a few written sources concerning so called specific kinds of partnership characterized by untypical joint and several responsibility of partners. Moreover these texts are not very clear and are difficult to interpret, so the issue of specific kinds of a partnership is a matter of doubts among Romanists. Some authors even believe that the specific types of partnership did not exist in the Roman law at all.It should be firstly observed that the texts regarding a contract of partnership itself (the texts included in the title pro socio of Justinian’ Digest) did not raise the question of the external liability of partners because they were devoted to internal settlement o f accounts within sociu Thus, taking into account only these texts one cannot ascertain that a conclusion of a contract of partnership could not affect in any way the model of the partners’ liability against third parties.Secondly, the other texts concerning the regulation of conducting an economic activity in the Roman law (actio institoria, actio exercitoria and actio de peculio) present some regularity in an introduction of joint and several liability of debtors.On the one hand that model of the liability was introduced in situations in which protecting safety of trade required that the creditor be able to claim a whole amount o f the debt from one person only.On the other hand this model of liability could be introduced only in these cases in which some internal relation existed between several debtors. On the grounds of such relations the debtor who satisfied in full the creditor’s claim could sue other debtors in order to recover their respective parts in the debt. In the Roman law that internal relation that guaranteed the possibility of a recourse could be either a joint-ownership or a partnership.Having considered that, one may say that the texts concerning specific kinds o f partnership do not prove existence of any special type of societas. These sources regard only the situations when a joint and several liability between several debtors was introduced because it was justified by the circumstances: that is the necessity to protect the safety of trade on one hand and the existence of the contract of partnership that guaranteed a possibility to realize the recourse, on the other.In conclusion one may say that although a closing of a contract of partnership did not create a joint and several liability of partners, in some cases its existence was decisive for introducing this model of liability since it guaranteed to every party a possibility to act against the others to obtain the recourse. Thus, Roman jurisprudence made an important step towards the future introduction o f joint and several liability of partners as a rule of a civil law.

To assist researchers to identify Environmental Microorganisms (EMs) effectively, a Multiscale CNN-CRF (MSCC) framework for the EM image segmentation is proposed in this paper. There are two parts in this framework: The first is a novel pixel-level segmentation approach, using a newly introduced Convolutional Neural Network (CNN), namely, “mU-Net-B3”, with a dense Conditional Random Field (CRF) postprocessing. The second is a VGG-16 based patch-level segmentation method with a novel “buffer” strategy, which further improves the segmentation quality of the details of the EMs. In the experiment, compared with the state-of-the-art methods on 420 EM images, the proposed MSCC method reduces the memory requirement from 355 MB to 103 MB, improves the overall evaluation indexes (Dice, Jaccard, Recall, Accuracy) from 85.24%, 77.42%, 82.27%, and 96.76% to 87.13%, 79.74%, 87.12%, and 96.91%, respectively, and reduces the volume overlap error from 22.58% to 20.26%. Therefore, the MSCC method shows great potential in the EM segmentation field.

Speaking as a productive skill is one of the very first obstacles that foreign language users face when using the language. Knowledge of a language does not refer to the correct and proper pronunciation however, being able to produce sounds, words or utterances in their proper way does not refer to proficiency of a language nor can it assess the overall level of the user of that particular language. The aim of this study is to present the components of speaking as a productive skill emphasizing the role of acquiring proper pronunciation as a factor for effective communication. The study also presents the most significant "common core" of English pronunciation as a lingua franca, details of the requested phonological competence as knowledge set by the Common European Framework of Languages: Learning, Teaching and Assessment and viewpoints of EFL teachers and authors. Additionally, the study includes data from EFL self- assessments from University students in Macedonia regarding their speaking and pronunciation skills and overall evaluation from their assessor –an English language instructor.

For lack of flexible description and the increasing complexity of data input, traditional modeling methods can not meet the demand of fast modeling for complicated bridge structures. Traditional methods are classified into the data based modeling and the graphic based modeling, and their disadvantages are discussed. On this condition, a new modeling method based on design drawings of AutoCAD is presented in this paper, which could fulfill the requirement of fast modeling and reflect the mechanic properties and internal relation of the structures. Especially, it can draw data from the AutoCAD lines automatically for analysis. The efficiency and reliability of the method has been proved by our software system WXQ developed for curved-skew bridges through a practical project.

Aiming at the limitation to the credit evaluating system of C2C, a multi-variables fuzzy reasoning model is constructed and the calculating scheme is designed to evaluate the sellers credit of C2C referring to the evaluating indexes of Taobao net. The score of credit indexes is defined by the form of continuous interval in the model based on the interdependent relationship between the global assessment and the secondary evaluation indexes. Since the effect of the subjective factors on credit rating is efficiently eliminating in the algorithm and the credit description is more close to the transaction fact, the rating results of credit got by fuzzy calculation is more reliable than the ones obtained by traditional evaluation method. To verify the effectiveness of the fuzzy method, an applied example is given under the background of Taobao transaction.

This paper aims to identify and analyze the advantages and disadvantages associated with building plan shape considering engineering and architectural needs and to quantify them in terms of the common language of costs and benefits. Parameters that measure the overall seismic response of a given plan shape were defined. Seismic behavior of the irregular shapes can be improved by means of special engineering efforts that provide enough in-plane slab stiffness and a distribution of lateral stiffness and strength so that torsion and distortion can be minimized. The proposed procedure of integral evaluation of buildings was applied to two specific examples, one regular and one irregular building, both with similar characteristics. The irregular building was seismically adequate by means of several dynamic analyses and a careful structural design so that it reached an acceptable level of seismic performance. For this example, the irregular building offers long-term benefits that exceed the initial investment required to improve its seismic behavior.
