Virtual world security inspection : a software inspection process carried out on popular virtual world environments

 Virtual property theft is a serious problem that exists in virtual worlds. Legitimate users of these worlds invest considerable amounts of time, effort and real-world money into obtaining virtual property, but unfortunately, are becoming victims of theft in high numbers. It is reported that there are over 1 billion registered users of virtual worlds containing virtual property items worth an estimated US$50 billion dollars. The problem of virtual property theft is complex, involving many legal, social and technological issues. The software used to access virtual worlds is of great importance as they form the primary interface to these worlds and as such the primary interface to conduct virtual property theft. The security vulnerabilities of virtual world applications have not, to date, been examined. This study aims to use the process of software inspection to discover security vulnerabilities that may exist within virtual world software – vulnerabilities that enable virtual property theft to occur. Analyzing three well know virtual world applications World of Warcraft, Guild Wars and Entropia Universe, this research utilized security analysis tools and scenario testing with focus on authentication, trading, intruder detection and virtual property recovery. It was discovered that all three examples were susceptible to keylogging, mail and direct trade methods were the most likely method for transferring stolen items, intrusion detection is of critical concern to all VWEs tested, stolen items were unable to be recovered in all cases and lastly occurrences of theft were undetectable in all cases. The results gained in this study present the key problem areas which need to be addressed to improve security and reduce the occurrence of virtual property theft.

Enhancing narrative coherence in simulated interviews about child abuse

Purpose – Simulated child interviews, where adults play the role of a child witness for trainee investigative interviewers, are an essential tool used to train investigators to adhere to non-leading, open-ended questions. The aim of this study is to examine whether the use of a training procedure that guides persons playing the role of a child in simulated interviews results in interviewees producing more coherent narratives (measured by the number of story grammar details).

Design/methodology/approach – A total of 80 police officers individually engaged in ten-minute interviews, whereby an untrained (colleague), or trained respondent, played the role of the child interviewee. For each child respondent condition, the interviews varied according to child age (five or eight years).

Findings – As predicted, trained respondents reported a higher proportion of story grammar elements and a lower proportion of contextual information than the untrained respondents, as well as more story grammar elements in response to open-ended questions. However, there were limitations in how well both groups tailored their story grammar to the age of the child they were representing.

Originality/value – These findings demonstrate that our training procedure promotes a more coherent interviewee account, and facilitates a response style that is more reinforcing of open-ended questions.

Popular consent and foreign policy choices : war against the Philippines and covert action in Chile

It is usually assumed that US policymakers need to generate popular consent in order to undertake regime change against another state. This article explores the ways in which contextual factors such as the joint democracy effect, popular values and public moods influenced efforts by elites in the United States to generate popular consent for regime change in the Philippines and Chile. Against the backdrop of the Vietnam War, the United States undertook covert action in Chile due to public recognition of the target state's democratic credentials and a public mood opposed to further military ventures. In contrast, the absence of a strong joint democracy effect, a national mood infused with romantic nationalism qua militarism and social Darwinism facilitated efforts by US elites to generate consent for the invasion and occupation of the Philippines. Subsequently, this article contributes to understandings of the domestic-level factors that influence foreign policy decisions.

Erotic capital, popular pedagogy, and healthy adolescent female sexuality

The sexualization of the female body in contemporary media has created considerable anxiety about its impact on girls. Much of the resulting research focuses on the influence of visual media on body image and the flow-on effects for girls' health. Rather less attention is paid to the pedagogical role of popular romance fiction in teaching girls about their sexuality. Given the pronounced increase in eroticized fiction for girls over the past decade, this is a significant oversight. This article applies Hakim's (2010) concept of erotic capital to two chick lit novels for girls. The elements of erotic capital—assets additional to economic, cultural and social capital—are used to explore the lessons these novels teach about girl sexual subjectivities and sociality in a sexualized culture.

Browsing behavior mimicking attacks on popular web sites for large botnets

With the significant growth of botnets, application layer DDoS attacks are much easier to launch using large botnet, and false negative is always a problem for intrusion detection systems in real practice. In this paper, we propose a novel application layer DDoS attack tool, which mimics human browsing behavior following three statistical distributions, the Zipf-like distribution for web page popularity, the Pareto distribution for page request time interval for an individual browser, and the inverse Gaussian distribution for length of browsing path. A Markov model is established for individual bot to generate attack request traffic. Our experiments indicated that the attack traffic that generated by the proposed tool is pretty similar to the real traffic. As a result, the current statistics based detection algorithms will result high false negative rate in general. In order to counter this kind of attacks, we discussed a few preliminary solutions at the end of this paper.

Reconstructing the south : how commercial myths compete for identity value through the ideological shaping of popular memories and countermemories

This study explicates the coconstitutive relationships between commercial myth- making and popular memory that arise through myth market competitions for identity value. We develop a genealogical analysis of the representational strategies and ideological rationales that two prominent New South mythmakers use to shape popular memories in relation to their competitive goals and to efface counter- memories that contradict their mythologized representations. We then derive a conceptual model that highlights competitive, historical, and ideological influences on commercial mythmaking and their transformative effects on popular memory, which have not been addressed by prior theorizations of the meaning transfer process.

A probabilistic framework for extracting narrative act boundaries and semantics in motion pictures

This work constitutes the first attempt to extract the important narrative structure, the 3-Act storytelling paradigm in film. Widely prevalent in the domain of film, it forms the foundation and framework in which a film can be made to function as an effective tool for story telling, and its extraction is a vital step in automatic content management for film data. The identification of act boundaries allows for structuralizing film at a level far higher than existing segmentation frameworks, which include shot detection and scene identification, and provides a basis for inferences about the semantic content of dramatic events in film. A novel act boundary likelihood function for Act 1 and 2 is derived using a Bayesian formulation under guidance from film grammar, tested under many configurations and the results are reported for experiments involving 25 full-length movies. The result proves to be a useful tool in both the automatic and semi-interactive setting for semantic analysis of film, with potential application to analogues occuring in many other domains, including news, training video, sitcoms.

Narrative structure detection through audio pace

We use the concept of film pace, expressed through the audio, to analyse the broad level narrative structure of film. The narrative structure is divided into visual narration, action sections, and audio narration, plot development sections. We hypothesise, that changes in the narrative structure signal a change in audio content, which is reflected by a change in audio pace. We test this hypothesis using a number of audio feature functions, that reflect the audio pace, to detect changes in narrative structure for 8 films of varying genres. The properties of the energy were then used to determine the. audio pace feature corresponding to the narrative, structure for each film analysed. The method was successful in determining the narrative structure for 1 of the films, achieving an overall precision of 76.4% and recall of 80.3%, We map the properties of the speech and energy of film audio to the higher level semantic concept of audio pace. The audio pace was in turn applied to a higher level semantic analysis of the structure of film.

Taming the roving camera : a framework for creating professional home movies through narrative and cinesthetic elements

In this paper we present an application designed to improve the quality of amateur video production. The majority of home movie material is negatively impacted by two factors: lack of narrative content- "what to shoot?", and the absence or inappropriate use of cinesthetic elements for effective reinforcement of content - "how to shoot?". We leverage the age-old communicative powers of Story to answer the what For the second problem, the how, we turn to the corpus of aesthetic principles that constitute the film profession, which impact both technical and cinematic considerations for a given project.

Narrative structure analysis with education and training videos for e-learning

This paper deals with the problem ofstructuralizing education and training videos for high-level semantics extraction and nonlinear media presentation in e-learning applications. Drawing guidance from production knowledge in instructional media, we propose six main narrative structures employed in education and training videos for both motivation and demonstration during learning and practical training. We devise a powerful audiovisual feature set, accompanied by a hierarchical decision tree-based classification system to determine and discriminate between these structures. Based on a two-liered hierarchical model, we demonstrate that we can achieve an accuracy of 84.7% on a comprehensive set of education and training video data.

Learners' incidental vocabulary acquisition : a case on narrative and expository texts

This study was intended to determine whether or not the genre of a reading text affects the incidental vocabulary acquisition of L2 learners while reading. To this aim, 40 Iranian EFL students whose vocabulary knowledge was within a limited range (already determined by Nation’s Vocabulary Levels Test) were divided into two groups of 20 each for the reading sections. The Narrative Group comprised the participants who read the narratives, and the Expository Group were those who read the expository texts. Three types of vocabulary tests (i.e., Form recognition, Meaning translation and Multiple-choice items) were administered after the reading sessions to assess the incidental vocabulary gains of the participants. Overall, this study demonstrated the relative superiority of expository texts over narratives in terms of enhancing readers' incidental acquisition of unknown words. It is argued that depending on the genre of a text, readers will invest processing resources with different depths and varying degrees of cognitive elaboration for the task of comprehension.

'Smart' technologies in early years literacy education: a meta-narrative of paradigmatic tensions in iPad use in an Australian preparatory classroom

With the revolution that has taken place in the functionality and uptake of portable networked ‘smart’ technologies, educators are looking to see what potential applications such technologies might have for school education. This article reports on a study into the use of portable personal computing devices in the early years of schooling. Specifically, it focuses on emerging patterns of use of Apple iPads in an Australian Preparatory (first year of compulsory schooling) classroom across the first year of implementation of these devices. We draw on student and teacher interviews and classroom observation data to provide a research meta-narrative of the intentions, practices and reflections of a ‘first year out’ teacher, and to discuss points of tension found in the contested space of early years literacy education, which are highlighted when potentially transformative technologies meet institutionalized literacy education practices. Our findings suggest that the broader policy and curriculum context of early years literacy education, and institutionalized practices found in this space, are potentially at odds with teacher-held intentions to transform learning through technology use, particularly with respect to tensions between print-based traditions and new digital literacies, and those between standards-based classroom curricular and more emancipatory agendas.
