The development of non-traditional communication channels in recent years has progressively created a world more digital, networked and interlaced by a myriad of communication tools than ever before. With Facebook being the most prevalent social network, this study aims to guide local organisations to use Facebook optimally to communicate with their customers. The study strives to incorporate the latest ideas about social media marketing in the relevant literature with the opinions of local social media marketing experts. The generally ineffective use of Facebook as a communication channel by small, inexperienced organisations is seen as a justification for identifying a set of criteria to guide organisations in using Facebook pages as a driver of communication. The empirical phase of the research produced a list of seven guidelines on the optimal use of Facebook pages for marketing purposes, which might assist South African companies in developing their marketing strategies. / Business Management / M.

One of the problems of semantic web is automated getting annotated data - web pages. Therefore this work is engaged in manual annotation of web pages and try to simplify this process for users using proposed methods. First part contains analysis of annotated data, users and vocabularies used for annotation. Afterwards are proposed methods which simplify annotation creation for users, the possibility of usage similar annotations or possibility highlight interesting parts of web page suitable for annotation. The work includes proposal of annotation tool user interface also that verifies proposed methods in practice. On the basis of this proposal was created a prototype implementation of the annotation tool Semantic Annotator as an extension for Google Chrome browser, which was also used for experiment verifying user-friendliness especially.

No. of bitstreams: 1 Deivis Fernandes Pirani.pdf: 1504986 bytes, checksum: e4989c06d3fc9c76df085862e18609d0 (MD5) Previous issue date: 2014-02-07 / This paper shows a field-trial investigation comparing the use of IPv4 and IPv6 protocols on web pages access considering the real user perspective and the transition period from IPv4 to IPv6. To perform this study, it was developed a testbed in which three adressing configurations of Internet Protocol, IPv4, IPv6, and Duas Stack (IPv4+IPv6), were used to access the top 100 world most visited web pages with an IPv6 enabled address. In addiction, several software tools were developed, that enabled more than 600 simultaneous accesses between IPv4, IPv6 and Dual Stack, to each of these pages. Those accesses were performed every hour during the period of a month, enabling to obtain more than 20 GB of information on the web access. Results showed that lower loading times obtained by IPv6 and Dual Stack are related to the partial acquisition of the content. In fact, for IPv6, the number of web pages with faster loading times goes from 57 to 20% when the average number of bytes obtained by IPv6 and the IPv4 is similar. For Dual Stack the number goes from 25 to 5% given the same conditions. It was also noted that 18 of the 100 pages which were considered, no content would be presented to the user in more than 50% of the performed accesses. Regarding the preference for IPv6 instead of IPv4, on Dual Stack it was observed that 90% of the acquired content for 27 of 100 web pages was made by IPv6. / Este trabalho apresenta um estudo de campo, comparativo, sobre a utiliza??o dos protocolos IPv4 e IPv6 no acesso a p?ginas web. Foi considerada a perspectiva de um usu?rio real deste tipo de servi?o, no atual per?odo de transi??o do IPv4 para o IPv6. Para que tal estudo pudesse ser realizado, foi desenvolvido um arranjo no qual tr?s configura??es de endere?amento do Protocolo de Internet, IPv4, IPv6 e Pilha Dupla (IPv4+IPv6), foram utilizadas nos acessos ?s 100 p?ginas web, com suporte ao I v6, mundialmente mais visitadas. Al?m disso, foram desenvolvidas uma s?rie de shell scripts que possibilitaram mais de 600 acessos simult?neos do IPv4, IPv6 e Pilha Dupla, a cada uma dessas p?ginas. Tais acessos foram executados de hora em hora, durante o per?odo de um m?s, possibilitando a obten??o de mais de 20 GB de informa??es relativas ao acesso web. Os resultados do estudo mostraram que os tempos de carregamento menores obtidos pelo IPv6 e pela Pilha Dupla, est?o relacionados com a aquisi??o parcial do conte?do. De fato, para o IPv6, o n?mero de p?ginas web com tempos de carregamento menores diminui de 57 para 20% quando a m?dia do n?mero de bytes obtidos pelo IPv6 e pelo IPv4 ? similar. Para a Pilha Dupla, dadas as mesmas condi??es, o n?mero diminui de 25 para 5%. Tamb?m foi observado que para 18 das 100 p?ginas web consideradas, nenhum conte?do foi apresentado ao usu?rio em mais de 50% dos acessos efetuados. Com rela??o ? prefer?ncia pelo IPv6 ao IPv4, na Pilha Dupla, observou-se que 90% da aquisi??o do conte?do, de 27 das 100 p?ginas web, ocorreu pelo IPv6.

Ένας σημαντικός παράγοντας για την αποτελεσματική συνεργασία μεταξύ των μελών ομάδας εργασίας, που είναι πρωταρχικής σημασίας για την επιτυχημένη υλοποίηση των τεχνικών έργων, είναι η αποδοτική επικοινωνία τους. Η επικοινωνία αυτή, όμως, δυσχεραίνεται λόγω του κατακερματισμού του κατασκευαστικού τομέα, του τεράστιου όγκου και της ποικιλομορφίας των πληροφοριών της διαδικασίας κατασκευής, των γεωγραφικών αποστάσεων μεταξύ του κεντρικού γραφείου της κατασκευαστικής εταιρίας και των εργοταξίων, καθώς και της μοναδικότητας και της πολυπλοκότητας των τεχνικών έργων. Οι προηγούμενες ερευνητικές προσπάθειες και οι εμπορικές εφαρμογές που σχετίζονται με τη διαχείριση πληροφοριών στη βιομηχανία των κατασκευών έχουν κυρίως επικεντρωθεί στην ηλεκτρονική διαχείριση εγγράφων (αλλά όχι ουσιαστικά στη διαχείριση πληροφοριών) και έχουν θέσει το εννοιολογικό πλαίσιο των διαδικτυακών βάσεων δεδομένων για τον κατασκευαστικό κλάδο. Περαιτέρω, μερικές ερευνητικές προσπάθειες έχουν οδηγήσει σε πιλοτική ανάπτυξη συστήματος διαχείρισης πληροφοριών, αλλά αυτές έχουν εστιάσει εν γένει σε μεμονωμένα τμήματα της κατασκευαστικής διαδικασίας και στις πιο βασικές πληροφορίες αυτών. Στα πλαίσια της εργασίας σχεδιάστηκε και αναπτύχθηκε ένα διαδικτυακό σύστημα διαχείρισης και διακίνησης πληροφοριών, ως προσπάθεια βελτίωσης της επικοινωνίας των συμμετεχόντων στην κατασκευαστική διαδικασία. Το σύστημα αποτελεί δεδομενο-κεντρική προσέγγιση, σε αντίθεση με τις εγγραφο-κεντρικές προσεγγίσεις των υπαρχόντων συστημάτων, και έχει δώσει έμφαση στον αναλυτικό σχεδιασμό της βάσης δεδομένων. Η ανάπτυξη του συστήματος βασίστηκε σε διερεύνηση που έγινε με χρήση ερωτηματολογίου και έδειξε ότι η ελληνική κατασκευαστική βιομηχανία δεν χρησιμοποιεί γενικά προηγμένα συστήματα διαχείρισης πληροφοριών κυρίως λόγω της περιορισμένης αποτελεσματικότητας των υπαρχόντων συστημάτων. Το προτεινόμενο σύστημα αποτελείται από μία δομημένη σχεσιακή βάση δεδομένων και μία δυναμική, οδηγούμενη από δεδομένα, διαδικτυακή εφαρμογή που επιτρέπει στους χρήστες του συστήματος να αλληλεπιδρούν μακρόθεν με τη βάση δεδομένων. Η βάση δεδομένων σχεδιάστηκε μετά από διερεύνηση και καταγραφή τόσο των χρηστών του συστήματος όσο και των απαιτούμενων πληροφοριών. Ο τελικός σχεδιασμός της βάσης δεδομένων, ο οποίος προέκυψε μετά από βρόχους μοντελοποίησης οντοτήτων και κανονικοποίησης, περιλαμβάνει 32 τύπους οντότητας με 42 σχέσεις μεταξύ τους και 172 ιδιότητες συνολικά. Ο σχεδιασμός της βάσης δεδομένων ολοκληρώθηκε με την ανάπτυξη 70 ερωτημάτων, που αποτελούν είτε συνδυασμό ανάκτησης δεδομένων που πληρούν συγκεκριμένα κριτήρια είτε προϊόντα επεξεργασίας των δεδομένων. Οι χρήστες του συστήματος μπορούν να αλληλεπιδρούν με τη βάση δεδομένων μέσω της διαδικτυακής εφαρμογής και να εκτελούν συγκεκριμένες λειτουργίες, όπως εισαγωγή, αναζήτηση, θέαση, τροποποίηση/ενημέρωση και διαγραφή δεδομένων. Η πρόσβαση στον ιστότοπο του συστήματος ελέγχεται με ονόματα και κωδικούς πρόσβασης. Η υλοποίηση της βάσης δεδομένων και της διαδικτυακής εφαρμογής έγινε με τα λογισμικά MS-Access και Dreamweaver MX αντίστοιχα. Ως τεχνολογία εξυπηρετητή χρησιμοποιήθηκαν οι Active Server Pages, ως γλώσσα προγραμματισμού η VBScript και ως εξυπηρετητής δικτύου ο Internet Information Server. Η λειτουργικότητα και η αποτελεσματικότητα του συστήματος ελέγχθηκαν με την πιλοτική εφαρμογή. Το σύστημα παρουσιάζει ικανοποιητική αποτελεσματικότητα ως προς τη δυναμική ενημέρωση των πληροφοριών, την επεξεργασία των δεδομένων και την παροχή αξιόπιστων αποτελεσμάτων. Με την αποκτηθείσα εμπειρία εκτιμάται ότι τα διαδικτυακά συστήματα διαχείρισης πληροφοριών με σχεδιασμό λεπτομερούς βάσης δεδομένων μπορούν να βελτιώσουν σημαντικά την επικοινωνία των συμμετεχόντων στην κατασκευή τεχνικών έργων με αποτέλεσμα την αύξηση της παραγωγικότητας της κατασκευαστικής ομάδας, την οικονομία χρόνου και πόρων, και τη βελτίωση της ποιότητας κατασκευής. / Communicating effectively among task groups is one of the most important factors for the success of a project. This communication, however, is hindered by the extended fragmentation of the construction industry, the large volumes and wide dissimilarity of the information involved in the construction process, and the uniqueness and complexity of construction projects. The distance between the construction company headquarters and construction sites augments the communication problem. Previous research efforts and commercial applications concerning information management for the construction industry have mainly focused on electronic document management and have set the conceptual framework of web databases for the construction industry. Further, some of the research efforts have included pilot implementation of management systems, but rather on parts of the construction process and including only the most basic information. A web-based system that facilitates construction information management and communication is designed and implemented. Unlike common document-based systems, the present work focuses on demonstrating the potential of data-centric web databases in enhancing the communication process during project execution. The system development has taken into consideration results from a questionnaire-based research in the Greek construction industry, which has indicated the absence of advanced information management systems, mainly because of the limited efficiency of existing systems. The proposed system consists of a relational database and a dynamic, data-driven web application that allows the end users to remotely interact with the database. The database design, which has been preceded by an end users analysis and an information analysis, has involved loops of entity modelling and normalisation. The database contains 32 tables with 42 relationships among them, a total of 172 fields, and 70 queries that constitute either retrieval of data that satisfy preset criteria or products of data processing. End users access the database through the internet and can perform certain transactions, such as insert, search, view, update, and delete data. The access to the system is controlled with usernames and passwords. The system has been implemented using MS-Access as the database management system and Macromedia Dreamweaver MX for developing the data-driven web application. Active Server Pages have been selected as server technology, VBScript as the programming language, and Internet Information Server as the web server. The effectiveness and efficiency of the system has been tested with a pilot application. Results from the pilot application demonstrate the technical feasibility of the system and its enhanced capability, compared to ordinary practices, to provide concise and reliable information, quick/remote access, and prompt updating potential. As a result, communication among project participants can improve, misunderstandings can be reduced or eliminated, and more time can be spent on decision-making. Ultimately, this will lead to increased productivity, time and cost savings, as well as to higher construction quality.

The apparent ‘invisibility’, or lack of representation of black men in contemporary mainstream gay visual cultures is the primary critical issue that the study engages with. The study presupposes that the frequency with which white men appear in popular representations of ‘gayness’ prevails over that of black men. In order to substantiate this assumption, this study analyses selected issues of the South African queer men’s lifestyle magazine Gay Pages. Gay visual cultures appear to simultaneously conflate ‘whiteness’ and normative homosexuality, while marginalising black gay men by means of positioning ‘blackness’ and ‘gayness’ as irreconcilable identity constructs. Images of the gay male ‘community’ disseminated by queer and mainstream media constantly offer stereotypical, distorted and race-biased notions of gay men, which ingrain the exclusive cultural equation of white men and ideal homomasculinity. The disclosure of racist and selectively homophobic ideologies, which seem to inform gay visual representation, is therefore the chief concern of the dissertation. By investigating selected images that ostensibly embody the complex cultural relationship between race and homomasculinity, the study addresses the following forms of visual representation: colonial representations of ‘blackness’; so-called gay ‘colonial’ representations; black self-representation; gay black self-representation; and contemporary representations of homomasculinity in advertisements and queer men’s lifestyle magazines such as Gay Pages. A genealogy of images is explored in order to illustrate the ways in which ‘blackness’ and ‘whiteness’ are respectively positioned as contradictory to and synonymous with dominant visual representations of homomasculinity in gay visual cultures. The hegemony of ‘whiteness’ in images sourced from colonial systems of representation, queer male art and commercial publicity, for example, are thus critiqued in order to address the various race-based prejudices that appear to be symptomatic of contemporary gay visual cultures.

Gemeinsamer Workshop von Universitaetsrechenzentrum und Professur Rechnernetze (Fakultaet Informatik) der TU Chemnitz. Globales Thema: Produktive und sichere Netzanwendungen

Modern architectures support multiple size pages to facilitate applications that use large chunks of contiguous memory either for buffer allocation, application specific memory management, in-memory caching or garbage collection. Most general purpose processors support larger page sizes, for e.g. x86 architecture supports 2MB and 1GB pages while PowerPC architecture supports 64KB, 16MB, 16GB pages. Such larger size pages are also known as superpages or huge pages. With the help of huge pages TLB reach can be increased significantly. The Linux kernel can transparently use these huge pages to significantly bring down the cost of TLB translations. With Transparent Huge Pages (THP) support in Linux kernel the end users or the application developers need not make any change to their application. Memory fragmentation which has been one of the classical problems in computing systems for decades is a key problem for the allocation of huge pages. Ubiquitous huge page support across architectures makes effective fragmentation management even more critical for modern systems. Applications tend to stress system TLB in the absence of huge pages, for virtual to physical address translation, which adversely affects performance/energy characteristics in long running systems. Since most kernel pages tend to be unmovable, fragmentation created due to their misplacement is more problematic and nearly impossible to recover with memory compaction. In this work, we explore physical memory manager of Linux and the interaction of kernel page placement with fragmentation avoidance and recovery mechanisms. Our analysis reveals that not only a random kernel page layout thwarts the progress of memory compaction; it can actually induce more fragmentation in the system. To address this problem, we propose a new allocator which takes special care for the placement of kernel pages. We propose a new region which represents memory area having kernel as well as user pages. Using this new region we introduce a staged allocator which with change in fragmentation level adapts and optimizes the kernel page placement. Later we introduce Illuminator which with zero overhead outperforms default kernel in terms of huge page allocation success rate and compaction overhead with respect to each huge page. We also show that huge page allocation is not a one dimensional problem but a two fold concern with how the fragmentation recovery mechanism may potentially interfere with the page clustering policy of allocator and worsen the fragmentation. Our results show that with effective kernel page placements the mixed page block counts reduces upto 70%, which allows our system to allocate 3x-4x huge pages than the default Kernel. Using these additional huge pages we show up to 38% improvement in terms of energy consumed and reduction in execution time up to 39% on standard benchmarks.
