FAST, PARALLEL AND SECURE CRYPTOGRAPHY ALGORITHM USING LORENZ`S ATTRACTOR

A novel cryptography method based on the Lorenz`s attractor chaotic system is presented. The proposed algorithm is secure and fast, making it practical for general use. We introduce the chaotic operation mode, which provides an interaction among the password, message and a chaotic system. It ensures that the algorithm yields a secure codification, even if the nature of the chaotic system is known. The algorithm has been implemented in two versions: one sequential and slow and the other, parallel and fast. Our algorithm assures the integrity of the ciphertext (we know if it has been altered, which is not assured by traditional algorithms) and consequently its authenticity. Numerical experiments are presented, discussed and show the behavior of the method in terms of security and performance. The fast version of the algorithm has a performance comparable to AES, a popular cryptography program used commercially nowadays, but it is more secure, which makes it immediately suitable for general purpose cryptography applications. An internet page has been set up, which enables the readers to test the algorithm and also to try to break into the cipher.

Hesitations and repair in German

The occurrence of pauses and hesitations in spontaneous speech has been shown to occur systematically, for example, "between sentences, after discourse markers and conjunctions and before accented content words." (Hansson [15]) This is certainly plausible in English, where pauses and hesitations can and often do occur before content words such as nominals, for example, "uh, there's a … man." (Chafe [8]) However, if hesitations are, in fact, evidence of "deciding what to talk about next," (Chafe [8]) then the complex grammatical system of German should render this pausing position precarious, since pre-modifiers must account for the gender of the nominals they modify.In this paper, I present data to test the hypothesis that pre-nominal hesitation patterns in German are dissimilar to those in English. Hesitations in German will be shown, in fact, to occur within noun phrase units. Nevertheless, native speakers most often succeed in supplying a nominal which conforms to the gender indicated by the determiner or pre-modifier. Corrections, or repairs, of infelicitous pre-modifiers indicate that the speaker was unable to supply a nominal of the same gender which the choice of pre-modifier had committed him/her to. The frequency of such repairs is shown to vary according to task, with fewest repairs occurring in elicited speech which allows for linguistic freedom and therefore is most like spontaneous speech. The data sets indicate that among German native speakers, hesitations occurring before noun phrase units (pre-NPU hesitations) indicate deliberation of what to say, while hesitations within or before the head of the noun phrase (pre-NPH hesitations) indicate deliberation of how to say what has already been decided (cf. Chafe [8]).

Language Dominance in Early and Late Bilinguals

The proposed presentation is a progress report from a project which is aimed at establishing some phonetic correlates of language dominance in various kinds of bilingual situations. The current object of study is Swedish students starting in classes which prepare for the International Baccalaureate (IB) programme. The IB classes in Sweden are taught in English, except for classes in Swedish and foreign languages. This means that after they enter the programme the students are exposed to and speak a good deal more English than previously.The assumption made by many students that they will, on the one hand not “damage” their Swedish, and on the other will dramatically improve their English simply by attending an English-medium school will be tested. The linguistic background of the students studied and their reasons for choosing the IB programme will be established. Their English and Swedish proficiency will be tested according to various parameters (native-like syntax, perceived foreign accent, the timing of vowels and consonants in VC sequences, vocabulary mobilisation) on arrival at the school, and again after one and three years at the school. The initial recordings are now underway.In a preliminary study involving just three young people who were bilingual in Swedish and English, the timing of the pronunciation of (C)VC syllables in Swedish and English was studied. The results of this investigation indicate that it may be possible to establish language dominance in bilingual speakers using timing data. It was found that the three subjects differed systematically in their pronunciation of the target words. One subject (15 years old), who was apparently native-like in both languages, had the V-C timing of both Swedish and English words of a native speaker of English. His brother (17 years old), who had a noticeable Swedish accent in English, pronounced both Swedish and English words in this respect like a native speaker of Swedish. The boys’ sister (9 years old) apparently had native-like timing in both languages.

Manipulation in Newspaper Articles : A Political Discourse Analysis of Lexical Choice and Manipulation in Japanese Newspaper Crisis Reporting in the case of North Korea

This paper analyzes some forms of linguistic manipulation in Japanese in newspapers when reporting on North Korea and its nuclear tests. The focus lies on lexical ambiguity in headlines and journalist’s voices in the body of the articles, that results in manipulation of the minds of the readers. The study is based on a corpus of nine articles from two of Japan’s largest newspapers Yomiuri Online and Asahi Shimbun Digital. The linguistic phenomenon that contribute to create manipulation are divided into Short Term Memory impact or Long Term Memory impact and examples will be discussed under each of the categories.The main results of the study are that headlines in Japanese newspapers do not make use of an ambiguous, double grounded structure. However, the articles are filled with explicit and implied attitudes as well as attributed material from people of a high social status, which suggests that manipulation of the long term memory is a tool used in Japanese media.

The priority of temporal aspects in L2-Swedish prosody : Studies in perception and production

Foreign accent can be everything from hardly detectable to rendering the second language speech unintelligible. It is assumed that certain aspects of a specific target language contribute more to making the foreign accented speech intelligible and listener friendly, than others. The present thesis examines a teaching strategy for Swedish pronunciation in second language education. The teaching strategy “Basic prosody” or BP, gives priority to temporal aspects of Swedish prosody, which means the temporal phonological contrasts word stress and quantity, as well as the durational realizations of these contrasts. BP does not prescribe any specific tonal realizations. This standpoint is based on the great regional variety in realization and distribution of Swedish word accents. The teaching strategy consists virtually of three directives: · Stress the proper word in the sentence. · Stress proper syllables in stressed words and make them longer. · Lengthen the proper segment – vowel or subsequent consonant – in the stressed syllable. These directives reflect the view that all phonological length is stress-induced, and that vowel length and consonant length are equally important as learning goals. BP is examined in the light of existing findings in the field of second language pronunciation and with respect to the phonetic correlates of Swedish stress and quantity. Five studies examine the relation between segment durations and the categorization made by native Swedish listeners. The results indicate that the postvocalic consonant duration contributes to quantity categorization as well as giving the proper duration to stressed syllables. Furthermore, native Swedish speakers are shown to apply the complementary /V: C/ - /VC:/ pattern also when speaking English and German, by lengthening postvocalic consonants. The correctness of the priority is not directly addressed but important aspects of BP are supported by earlier findings as well as the results from the present studies.

Attitudes Towards and Uses of the Japanese Adverbzenzen by Swedish Learners of Japanese

The word zenzen is an adverb that is used frequently in daily conversational Japanese. From the Meiji period (1868-1912) until the early Showa period (1924-1989) the word was used together with both affirmative and negative words to form expressions. In the early Showa period the grammatical rules in education changed so that the only acceptable use was together with a negative word. From the 1990’s onward, the use together with an affirmative word has made a comeback especially among younger Japanese people. However even though the usage together with an affirmative word has made a comeback and was considered normal once in history, in today’s society it is still considered as slang and thus not recommended usage in formal situations. Foreign language learners however, tend not to learn a language only by textbooks but also by imitating the language of native Japanese speakers and Japanese popular culture. This may lead to a confusion regarding what words are acceptable to use in conversations. Therefore in this study, an online survey that examines the usage and attitudes regarding the word zenzen aimed at Japanese language learners at Swedish universities was conducted. The results of the survey showed that although a majority of the learners showed a good understanding of the usage, more than half of the learners displayed a feeling of confusion regarding the usage of the word. The gender comparison regarding the usage showed no major differences. Having lived in Japan, having Japanese friends whom you speak Japanese with regularly and length of Japanese study was associated with an increased understanding of the usage. Regular consumption of Japanese popular culture, however, was not associated with an increased understanding of the usage. A literature analysis was also conducted to examine the attitudes regarding the usage of zenzen in a variety of books with topics including business language and books aimed at Japanese language teachers. The results showed that zenzen used together with a negative word was considered as the norm while zenzen used together with an affirmative word was not recommended to be used in formal situations. When recommending proper usage of the word zenzen together with an affirmative word to foreign learners of Japanese, hijou-ni and totemo was seen as better alternatives to zenzen in a formal situation.

Abilities and Cultural Understanding through Literature in the EFL Classroom : - A Literature Review

The English language can be seen as a lingua franca of contemporary times. Its spread and use in the globalized world has affected most levels of society and it can be argued that, in current times, English is synonymous with communication. This need for communication has shaped the English as a Foreign Language (EFL) syllabus, which is evident in the Swedish national steering documents for the educational system. For the upper secondary school these documents show an emphasis on communication, on cultural understanding, and also on the use of literature within the EFL classroom. The need to possess communicative abilities and cultural understanding, in connection with the use of literature, has sparked an interest to investigate if and how literature itself can be used as a tool to develop and improve EFL students’ communicative skills and cultural understanding. This literature review thesis analyzes five international research articles from different geographical parts of the Globe. The findings are categorized, compared, synthesized, and finally discussed in order to answer the research questions asked, and also compared with the English subject syllabus for the Swedish upper secondary school. The findings indicate that the analyzed articles share a consensus, to a varied degree, regarding the positive aspects of literature use in the EFL setting. The arguments are that communicative skills and cultural understanding are intertwined - enabling each other to exist, develop, and improve. One cannot exist fully without the other, and literature is a good tool to use to develop and improve these abilities. Literature can help develop all skills needed to acquire and produce both written and spoken English, and it also enables cultural understanding and a broadening of the mind. Where the articles differ somewhat is in the ideas of why literature is a good tool, how to implement literature in the classrooms, and what some of the negative aspects might be. The thesis also brings the lack of Swedish studies within EFL to the readers’ attention, as well as the need to do more research focusing on the students’ perspectives towards literature use in the EFL setting.

Sports and mediatization : a case of women´s ski-jumping

Ski jumping was the only sport included in the Winter Olympics, where women were not allowed to take part until the first week of April 2011, when IOC decided to let them in to the Olympic family, a major victory for women´s ski-jumping. Since 2004 the Norwegian media had women ski jumping as one important topic in their media coverage. The third of March 2010 the new Holmenkollen ski-jumping hill was inaugurated. It had been rebuilt for the World Championships 2011. The first jump on the hill was surrounded by an intense debate. Annette Sagen was decided to be the first jumper on the hill after a poll on the social media channel Facebook that gave Annette Sagen over 40 000 votes.  However Tuesday the second of March Björn Einar Romören, a world cup jumper, did the first jump during a training session. This act started a significant chain of events. The biggest Norwegian web – magazines Verldens Gang and Aftenposten made this the head story and they invited the readers to interaction. Within 24 hours 11 000 comments were written, most of them in favor of Sagen and against Romören´s behavior. The Norwegian Ski Association excluded Romören from two World Cup competitions. What did happen during these days in the media?  I want to present the activities, which went on in two web-magazines, and analyze the articles written on the topic. Main issues are to show what an impact a social media network had on the sport in this specific case and how different actors appeared in the media and discuss if Romörens exclusion was a result of the mediatization.

The use of the pronouns we, us, and our in political speeches : A comparative study of the inaugural addresses of Bush and Obama

Pronouns carry considerable importance in language. The speaker’s identity and connection to the audience emerges through the consistent use of certain pronouns (De Fina, 1995). This research is about the use of we, us, and our in political discourse. Specifically, their use will be examined in the inaugural addresses of George W. Bush in 2005 and Barack Obama in 2009. The aim of this research is to examine the frequencies and the co-occurrences of these pronouns and then compare their use in these two speeches. More specifically, how do the pronouns examined affect the message and enhance hearer credibility. This is done by applying (a) a quantitative corpus linguistics analysis and (b) qualitative analysis of the context of use. The results show that there is a difference in frequency of pronoun use; however, the usage of pronouns is rather similar in the two speeches

Processes and variations in language economisation

This article analyses the processes of reducing language in textchats produced by non-native speakers of English. We propose that forms are reduced because of their high frequency and because of the discourse context. A wide variety of processes are attested in the literature, and we find different forms of clippings in our data, including mixtures of different clippings, homophone respellings, phonetic respellings including informal oral forms, initialisms (but no acronyms), and mixtures of clipping together with homophone and phonetic respellings. Clippings were the most frequent process (especially back-clippings and initialisms), followed by homophone respellings. There were different ways of metalinguistically marking reduction, but capitalisation was by far the most frequent. There is much individual variation in the frequencies of the different processes, although most were within normal distribution. The fact that nonnative speakers seem to generally follow reduction patterns of native speakers suggests that reduction is a universal process.

Topic- and mode-sensitive interaction strategies : Functions of ellipsis in oral communication

In this article, we discuss ellipsis as an interactive strategy by analysing the author’s textchat corpus and the VOICE corpus of English as a Lingua Franca. It is found that there were fewer repetitions in the textchat data, and this is explained as a consequence of the textchat mode. Textchat contributions are preserved as long as the chat is active or has been saved, and therefore users can scroll through and review the discussion, compared to the more fleeting nature of oral conversation. As a result, repetition is less necessary. The frequency of other functions identified could be attributed to the topic of discourse. Discussions involve much ellipsis used to develop discourse, although some were self-presentations with repetition used to confirm details. Back-channel support and comments were often low because speakers instead used forms like yeah as supportive utterances.

Literary Love Making in Nicholas Sparks Novels: Finding the Balance Between the Writer's Life and Writer's Work in Bestselling Romantic Love

For almost a decade now Nicholas Sparks has been writing love stories. Not only has he been publishing his stories, but they have received high acclaim in each of their installments. Several of his novels have been made into major motion pictures and increased his popularity quite significantly. His status as a successful romantic fiction writer is undeniable, but the question is, why? What is it about Nicholas Sparks that makes his novels so engaging, and personally, what do I need to do as an aspiring novelist to try and acquire the same literary status? Sparks’s novels reach readers at a number of different levels, thus giving them appeal no matter the intellectual intent of the reader. Theoretically, Sparks engages reader response techniques as well as formalist processes such as “habitualization” and “defamiliarization,” while also developing engaging plot lines that represent many of the experiences from his own life. His writing is not only academically redeemable, but it is also creatively stimulating; between the two, Sparks represents the thunder and lightning combination all writers strive for while trying to achieve literary success. This project also offers a creative element in which I attempt to exemplify many of the traits discussed in the analytical sections of this document, by recreating them in a creative, fictitious fashion. Themes such as: motion versus stasis, life versus death, and the ordinary versus the extraordinary all exist within the narrative structure of my short story “Trip to Fall.” Besides these thematic elements, the creative section strives to represent the balance Sparks achieves between the experiences of his own life and the fictitious world he creates. Overall, this project delves into the life of Nicholas Sparks to better understand the inspiration for his writing at the level of form as well as content, while also paying tribute to Sparks’s style through a representation of his work in my own words.

The Tastes of a Nation: M.F.K. Fisher and the Genre of Culinary Literature

This project works to situate this gastronomic revolution within a historical context, arguing at greater length that our contemporary food culture in the United States is in part the legacy of the body of food representations. Here we witness the evolution of a particular culinary sensibility that appealed to readers differently in different historical moments, as exhibited by the variety of ways that Fisher’s body of work was publicly received. By the end of the twentieth century, Fisher’s ethos reigned supreme, because Americans began to view food with less fear and anxiety as they slowly became more comfortable expressing their physical appetites and desires. By the millennium, Americans began to respect and honor the physical appetite and give more consideration to the quality and origin of the foods that they consumed. Feelings of guilt associated with the enjoyment of food began to diminish as well.

Where did all these books come from? The Publishing Industry and American Intellectual Life

The American book publishing industry shapes the character of American intellectual life. While the newspaper and television industries have been accused of and investigated for bias and lowering America’s intellectual standards, book publishing has gone largely unexamined by scholars. The existing studies of the publishing industry have focused on finance, procedure and history. “There are few ‘theories’ of publishing – efforts to understand the ‘whys’ as well as the ‘hows.’ Few scholarly scientists have devoted significant scholarly attention to publishing” (Altbach and Hoshino, xiii). There are many possible reasons for this lacuna. First, there is a perception that books have always been around, that they are an “old” technology and therefore they don’t appear to have had as much of an impact on our society as television and other media (which were developed quickly and suddenly) seem to have had (Altbach and Hoshino, xiv). Also, despite books’ present and past popularity, television, radio, and now the internet reach more people more easily, and are therefore more topical points of study and observation. In studying the effects of mass media on everyday American life, television and the internet may be the most logical points of study. Regarding public intellectual life however, books play a much more important role. Public intellectual life has always been associated with independent thinkers publishing their work for the masses. For this reason, this I focus on trade publishing. Trade publishing produces fiction and non-fiction works for the general reading public, as opposed to technical manuals, textbooks, and other fiction and nonfiction books targeted to small and specific audiences. Although, quantitatively speaking, “the largest part of book publishing business is embodied in that great complex of companies and activities producing educational, business, scientific, technical, and reference books and materials,” (Tebbel 1987, 439) the trade industry publishes most of the books that most people read. It is the most public segment of the industry, and the most likely place to find public intellectualism. Trade publishing is not only the most public segment of the industry, but it is also the most susceptible to corruption and lowered intellectual standards. Unlike specialty publishing, which caters to a specific, known segment of society, trade publishers must compete with countless other publications, as well as with other forms of media, for the patronage of the general public. As John Tebbel (author of a widely referenced history of the publishing industry) puts it, “The textbook, scientific, or technical book is subjected to much more rigorous scrutiny by buyers and users, and in an intensively competitive market inferior products are quickly lost" (Tebbel 1987, xiv). Since the standards for trade publishing are not nearly as specific – trade books simply need to catch the attention of a significant number of readers, they don’t have to measure up to a given level of quality – the quality of trade books is much more variable. And yet, a successful trade publication can have a much greater impact on society than the most rigorously researched and edited textbook or scholarly study.
