完善审美个性——“语文教学中的审美教育实践”专题七

审美的共通性是美育的基础和前提,而审美的个性化是美育的目标和境界。个性是个体生命的本质所在,审美个性的参差多态正是人类幸福的本源。教师应当以明识催生明识,促进学生将审美偏见转化为审美个性;在感受想象力的“自由”的同时,发现文学创作的“限制”———在语言文字运用方面的审美规律。在保持个体独立性的同时,促进个体与群体的和谐:自身的分寸感、与他者的呼应。

A Location Privacy Preserving Solution to Resist Passive and Active Attacks in VANET

Existing location privacy- preserving methods, without a trusted third party, cannot resist conspiracy attacks and active attacks. This paper proposes a novel solution for location based service （LBS） in vehicular ad hoc network （VANET）. Firstly, the relationship among anonymity degree, expected company area and vehicle density is discussed. Then, a companion set F is set up by k neighbor vehicles. Based on secure multi-party computation, each vehicle in V can compute the centroid, not revealing its location to each other. The centroid as a cloaking location is sent to LBS provider （P） and P returns a point of interest （POI）. Due to a distributed secret sharing structure, P cannot obtain the positions of non-complicity vehicles by colluding with multiple internal vehicles. To detect fake data from dishonest vehicles, zero knowledge proof is adopted. Comparing with other related methods, our solution can resist passive and active attacks from internal and external nodes. It provides strong privacy protection for LBS in VANET.

Natural Philosophy, Inventions and Religion in the Correspondence between John Locke and Nicolas Toinard （1678-1704）

The paper examines the copious correspondence between the English philosopher John Locke （1632-1704） and the French intellectual Nicolas Toinard （1629-1706）; Locke made the acquaintance of Toinard in Paris in 1677 or early in 1678, and the latter remained his lifelong friend and most assiduous correspondent. An Orl6anais and a devout Catholic, Toinard combined an intense interest in the Scriptures with an enthusiasm for experimental science and inventions of every kind; he introduced Locke to all the French official institutions and to a number of private laboratories. Toinard＇s principal work, Evangeliorum Harmonia Graeco-Latina, was greatly appreciated by Locke for its new method. The paper attempts at exploring the bulk of this correspondence in detail, giving an account of the wide range of topics dealt with in the two hundred letters; it is divided into four paragraphs referring, respectively, to the years 1678-1679, 1679-1681, 1681-1686, and1686-1704. The perspective is diachronic; in some occasions, the focus is on a peculiar topic which is the object of prolonged discussion between the two correspondents. In the conclusion, attention is drawn to the relevance of this correspondence in the context of the 17th century and of Locke＇s philosophical thought.

Shared Ideas,Divergent Approaches:The Hydromethods of the Great West(Taixi shuifa泰西水法)and the Question on Tides

One of the questions about natural phenomena asked in the Hydromethods of the Great West(Taixi shuifa泰西水法;1612)(hereafter TXSF),composed by the Italian Jesuit Sabatino de Ursis with the support of the Chinese official Xu Guangqi徐光啟,concerns the causes of sea tides.The idiosyncratic answer given in the TXSF serves as an example for the Jesuit missionaries,strategically motivated approach to the transfer of knowledge through the translation of Western scientific thought into Chinese.From a chronological overview of the attempts made both in the East and in the West to theoretically conceptualize the causes of the cyclical occurrence of ebb and flow,the comparison reveals that despite being based on totally different cosmologies,the related insights were virtually on a par.The aim to nevertheless convince the audience of the TXSF of the superiority of Western sciences resulted in a particular rhetoric and a division of tasks in the composition of the tides paragraph.In order to verify the success of this joint effort of de Ursis and Xu Guangqi,a change of perspective from the transmitter to the receiver side is necessary.Thus,the paper also explores the work's reception in later Chinese works dealing with this topic.

The Decisive Moment as an Event in Photographic Discourse

We propose using the concept of decisive moment in order to deconstruct the obvious ideological effects found in discourse. The subject is constituted in enunciation, and its polysemic discourse clashes with the transparency of meaning. According to Pêcheux （1988）, the contradictions in discourse simultaneously establish regularity and instability of meanings, leading it to misunderstanding, to the event. Photography destabilizes that which is already formulated and brings out that which is new, the unexpected meaning, the decisive moment. We analyze this process in the picture by Sebastiao Salgado---＂The cradle of inequality lies in the inequality of the cradle＂. （CAPES-BEX 4394/10-0, FAPESP 09/54417-4, CNPq.）

Recognition of human face based on improved multi-sample

In order to solve the problem caused by variation illumination in human face recognition,we bring forward a face recognition algorithm based on the improved multi-sample. In this algorithm,the face image is processed with Retinex theory,meanwhile,the Gabor filter is adopted to perform the feature extraction. The experimental results show that the application of Retinex theory improves the recognition accuracy,and makes the algorithm more robust to the variation illumination. The Gabor filter is more effective and accurate for extracting more useable facial local features. It is proved that the proposed algorithm has good recognition accuracy and it is stable under variation illumination.

Study on RFID Authentication Protocol Theory

Secure and private authentication protocol is important in Radio Frequency Identification (RFID) technology.To date,researchers have proposed many RFID authentication protocols.However,these protocols have many flaws due to lack of theoretical support in designing these protocols.In this work,first we present the security and privacy requirements in RFID authentication protocols.Then we examine related works and point out problems in designing RFID authentication protocols.To solve these problems,we propose and briefly prove three theorems.We also give necessary examples for better understanding these theorems with concrete protocols.At last,we give our suggestions on designing secure and private authentication protocols.The security and privacy requirements,theorems,and suggestions will facilitate better understanding and designing of RFID authentication protocols in the future.

The Relation between Theory and Practice in Muslim Sages＇ Thoughts in the Third and Fourth Hijra Centuries and Its Effects on Concept of Craft （Sana＇at） and Art in Islamic Civilization

Farabi defines ＂Ilm al-Hiyal＂ （mechanic） in Ihsa al-Ulum as ＂knowing a way by which, human can adjust all of the concepts that have been proved in mathematics with verification to exotic objects, and helps their states in exotic objects to be carried＂. He believes this will be recognized and be attained by craft （sana＇at, art）. This was the common view in Islamic wisdom and philosophy in third and fourth Hijra centuries （9 ＆ 10 CE）. Researchers believe that the unique emphasis on parallelism between theoretical science and practical work is an important feature of Baghdad school and affected Islamic visual culture. Baghdad school had been affected by translation. In this way, Ikhwan-al-Safa, whom wrote the first encyclopedia of science in Islamic culture, had a very efficient role. They devised geometry into intellectual and sensual ones in the second part of their book, al-Rasa-el, and considered intellectual geometry as one of the middle philosophy and recognition and understanding factor for meaning of sensual geometry evidences. They insisted on basic situation of intellectual geometry in guidance of whom, want to learn intellectual things from sensual ones. They knew intellectual geometry as the factor for requiring skill in scientific crafts （sana＇at）, and sensual geometry as the factor of practical crafts, and made a vast relation between them. They also defined end of intellectual geometry understanding the base of all sciences and the main factor of wise, essence of self （nafs）. Important feature of Ikhwan-al-Safa＇s wisdom is omitting the gap between theory and practice, making a vast relation between them, which affected the meaning of crafts in Islamic culture, and rendered a spiritual feature to crafts and arts. It seems this relation has created the concept of traditional arts, and integrating wisdom and crafts in Iranian-Islamic culture constructed all of the Fotowat-Nam e （book of Chivalry）. This article reviews the concept, which affiliates theory and practice in third and fourth centuries and has a deep effect on recognition of art and craft in Islamic culture.

Art and Design in context of the new economic era

Human beings realize we have entered a modem society because of their awareness and understanding of social responsibility, recognizing that art is not only as a mirror to reflect the results of the present social processes, but also as a necessary means to promote social progress, that is to say that there is no modern society without modenl art. Modem design is closely related to human life. With twenty-first century the process of globalization accelerating, modem design in the promotion of modern human civilization takes responsibility, and also raises the batmer of human civilization, standing on high level of awareness of globalization and development of modem design.

Mathematics Knowledge of Proof in Geometry： Pre-Service Teachers＇ Perspectives

This article is based on research on pre-service teachers＇ perspectives on their mathematics knowledge of proof in geometry. The study was framed using tile mathematical knowledge for teaching framework. This qualitative study employed the use of a task-based worksheet, focus group sessions and semi-structured individual interviews. The task-based worksheet was completed by 180 pre-service mathematics teachers （second, third and fourth year mathematics education students）. Pre-service mathematics teachers are student teachers who have not yet completed their training to become teachers. After the analysis of the task-based worksheet, 20 participants were invited to participate in focus group sessions and individual interviews. The findings of the study reveal that the participants possess peripheral mathematics knowledge of proof in geometry. The study aims at assisting pre-service teachers and interested educationists to explore innovative methods of acquiring and imparting mathematics knowledge of proof in geometry. The study proposes possible changes in curriculum at school and university level.

An Analysis of Japan＇s Interpretation of History over the Seven Postwar Decades

During the seven decades since the war ended, Japan has undergone ＂changes of direction＂ involving group expressions of regret, accompanied by the intellectual ＂soul- searching＂ of quite a few academics. Ultimately, however, the country has been unable to complete the ＂transformation＂ of its political values. Its consciousness of superiority, dating back to the Meiji era, and its dream of being restored to the status of a ＂normal country＂ have distorted Japan＇s idea of the war and its interpretation of history. As a result, at the critical postwar moment when Japan most needed to develop a truthful view of its history, its national will expressed itself in the rejection of this possibility. Japan has manufactured Sino-Japanese friction and manipulated the United States, on the pretext of a supposed ＂China threat＂ into relaxing the constraints upon Japan, and has attempted to abandon the thought and deeds of the postwar international order. Not only has this repeatedly subverted the standards by which the intemational ＂left＂ and ＂right＂ assess Japan; it has also once again placed the Asia-Pacific region in a precarious position.

Identity-based Broadcast Encryption with Shorter Transmissions

This paper describes two identity-based broadcast encryption （IBBE） schemes for mobile ad hoc networks. The first scheme proposed achieves sub-linear size cipertexts and the second scheme achieves O（1）- size ciphertexts. Furthermore, when the public keys are transmitted, the two schemes have short transmissions and achieve O（1） user storage cost, which are important for a mobile ad hoc network. Finally, the proposed schemes are provable security under the decision generalized bilinear Diffi-Hellman （GBDH） assumption in the random oracles model.

Adaptive Illumination Normalization Approach Based on Denoising Technique for Face Recognition

A novel adaptive illumination normalization approach is proposed to eliminate the effects caused by illumination variations for face recognition. The proposed method divides an image into blocks and performs discrete cosine transform(DCT) in blocks independently in the logarithm domain. For each block-DCT coefficient except the direct current(DC) component, we take the illumination as main signal and take the reflectance as "noise". A data-driven and adaptive soft-thresholding denoising technique is employed in each block-DCT coefficient except the DC component. Illumination is estimated by applying the inverse DCT in the block-DCT coefficients, and the indirectly obtained reflectance can be used in further recognition task. Experimental results show that the proposed approach outperforms other existing methods. Moreover, the proposed method does not need any prior information, and none of the parameters can be determined by experience.

Precise Zero-Knowledge Arguments with Poly-logarithmic Efficiency

Precise zero-knowledge was introduced by Micali and Pass in STOC06. This notion captures the idea that the view of a verifier can be reconstructed in almost same time. Following the notion, they constructed some precise zero-knowledge proofs and arguments, in which the communicated messages are polynomial bits. In this paper, we employ the new simulation technique introduced by them to provide a precise simulator for a modified Kilian＇s zero-knowledge arguments with poly-logarithmic efficiency （this modification addressed by Rosen）, and as a result we show this protocol is a precise zero-knowledge argument with poly-logaxithmic efficiency. We also present an alternative construction of the desired protocols.

The Animals of China in the Eighteenth-Century British Imagination

In eighteenth-century Britain, knowledge about animals from around the world was rapidly increasing. This paper focuses on what the British knew and imagined about the animals of China from reading the works of European travellers and natural historians. Whereas the animals of Africa and America served to foster a growing sense of European mastery of less civilized parts of the world through trade and possession, those of China were understood as embedded in a highly advanced civilization and therefore as sources of knowledge about that civilization. This paper examines the way in which British understandings of China were mediated through accounts of Chinese animals and of human-animal relations in China. Looking at works of popular natural history and at Oliver Goldsmith＇s fictional letters of a ＂Chinese philosopher＂ in The Citizen of the World （1762）, I argue that the animals of China bore several messages about their country. Focusing on the particular examples of the golden pheasant, the horse, the cormorant, and the cat, I suggest that British writing about Chinese animals served as a way of expressing mixed feelings about the value of advanced civilizations, whether Chinese or European.

Filling the Gap between Voters and Cryptography in e-Voting

Cryptography is an important tool in the design and implementation of e-voting schemes since it can provide verifiability, which is not provided in the traditional voting. But in the real life, most voters can neither understand the profound theory of cryptography nor perform the complicated cryptographic computation. An e-voting system is presented in this paper to leverage the use of cryptography. It combines the advantages of voting scheme of Moran-Naor and voting scheme based on homomorphic encryption. It makes use of the cryptographic technique, but it hides the details of cryptographic computation from voters. Compared with voting scheme of Moran-Naor, the new system has three advantages: the ballots can be recovered when the voting machine breaks down, the costly cut-and-choose zero-knowledge proofs for shuffling votes made by the voting machine are avoided and the partial tally result in each voting machine can be kept secret.

SEVERAL CRYPTOGRAPHIC APPLICATIONS OF ∑-PROTOCOL

∑-protocol has been proved to be a very powerful cryptographic tool and widely used in nnmerous important cryptographic applications. In this paper, the authors make use of ∑-protocol as a main tool to resolve the following difficult problems 1-3 and to construct three ettlcient cryptographic protocols 4 6：1） How to construct a protocol for proving a secret integer to be a Blum integer with form PQ, where P, Q are two different primes and both -- 3（mod 4）;2） How to construct a protocol for proving a secret polynomial with exact degree t - 1 iil a （t, n）- threshold secret sharing scheme：3） How to construct witness indistinguishable and witness hiding protocol not from zero-knowledge proof;4） A publicly verifiable secret sharing scheme with information-theoretic security;5） A delegateable signature scheme under the existence of one-way permutations;6） Non-interactive universal designated verifier signature schemes.

Unbiased Condition of the Dispersion Effects Estimator in Unreplicated Two-Level Factorial Experiments

This article presents a general form of the estimator for identifying dispersion effects from unreplicated two-level factorial experiments,and shows that the widely used estimators such as the BH,MH,and AMH estimators are all special cases of the proposed one,designated as the G estimator.The unbiased condition of the G estimator is proved,and a lower bound of variance of the G estimator is provided.A simulation based on a realistic design illustrates the variation of the variance and MSE(mean square error) of the G estimator on different coefficients.This estimator may be more flexible and has better performance than other methods such as the BH and MH estimators by appropriately selecting the coefficients.

The Many Sounds of Civilization

British-American historian Bernard Lewis famously condemned Arab and Islamic civilization for not having a polyphonic sense of music,even accusing them of accepting totalitarian ideologies and regimes because of their taste for"monophonic"music.That is,having one single singer with all the music following the ups and downs of his or her voice.Polyphonic music,by contrast,is when a piece of music has two or more independent melodies in it.As for the related notion of counterpoint,this is from many voices present in the chorus of a classical Greek drama and a reference to the coordination evident in choir singing.
