Attributes of identity document credibility: A synthesis of expert knowledge

In broad terms — including a thief's use of existing credit card, bank, or other accounts — the number of identity fraud victims in the United States ranges 9-10 million per year, or roughly 4% of the US adult population. The average annual theft per stolen identity was estimated at $6,383 in 2006, up approximately 22% from $5,248 in 2003; an increase in estimated total theft from $53.2 billion in 2003 to $56.6 billion in 2006. About three million Americans each year fall victim to the worst kind of identity fraud: new account fraud. Names, Social Security numbers, dates of birth, and other data are acquired fraudulently from the issuing organization, or from the victim then these data are used to create fraudulent identity documents. In turn, these are presented to other organizations as evidence of identity, used to open new lines of credit, secure loans, “flip” property, or otherwise turn a profit in a victim's name. This is much more time consuming — and typically more costly — to repair than fraudulent use of existing accounts. ^ This research borrows from well-established theoretical backgrounds, in an effort to answer the question – what is it that makes identity documents credible? Most importantly, identification of the components of credibility draws upon personal construct psychology, the underpinning for the repertory grid technique, a form of structured interviewing that arrives at a description of the interviewee’s constructs on a given topic, such as credibility of identity documents. This represents substantial contribution to theory, being the first research to use the repertory grid technique to elicit from experts, their mental constructs used to evaluate credibility of different types of identity documents reviewed in the course of opening new accounts. The research identified twenty-one characteristics, different ones of which are present on different types of identity documents. Expert evaluations of these documents in different scenarios suggest that visual characteristics are most important for a physical document, while authenticated personal data are most important for a digital document. ^

Diseño, desarrollo y evaluación de sistemas de traducción automática para reducir las barreras de comunicación de las personas sordas

La principal aportación de esta tesis doctoral ha sido la propuesta y evaluación de un sistema de traducción automática que permite la comunicación entre personas oyentes y sordas. Este sistema está formado a su vez por dos sistemas: un traductor de habla en español a Lengua de Signos Española (LSE) escrita y que posteriormente se representa mediante un agente animado; y un generador de habla en español a partir de una secuencia de signos escritos mediante glosas. El primero de ellos consta de un reconocedor de habla, un módulo de traducción entre lenguas y un agente animado que representa los signos en LSE. El segundo sistema está formado por una interfaz gráfica donde se puede especificar una secuencia de signos mediante glosas (palabras en mayúscula que representan los signos), un módulo de traducción entre lenguas y un conversor texto-habla. Para el desarrollo del sistema de traducción, en primer lugar se ha generado un corpus paralelo de 7696 frases en español con sus correspondientes traducciones a LSE. Estas frases pertenecen a cuatro dominios de aplicación distintos: la renovación del Documento Nacional de Identidad, la renovación del permiso de conducir, un servicio de información de autobuses urbanos y la recepción de un hotel. Además, se ha generado una base de datos con más de 1000 signos almacenados en cuatro sistemas distintos de signo-escritura. En segundo lugar, se ha desarrollado un módulo de traducción automática que integra dos técnicas de traducción con una estructura jerárquica: la primera basada en memoria y la segunda estadística. Además, se ha implementado un módulo de pre-procesamiento de las frases en español que, mediante su incorporación al módulo de traducción estadística, permite mejorar significativamente la tasa de traducción. En esta tesis también se ha mejorado la versión de la interfaz de traducción de LSE a habla. Por un lado, se han incorporado nuevas características que mejoran su usabilidad y, por otro, se ha integrado un traductor de lenguaje SMS (Short Message Service – Servicio de Mensajes Cortos) a español, que permite especificar la secuencia a traducir en lenguaje SMS, además de mediante una secuencia de glosas. El sistema de traducción propuesto se ha evaluado con usuarios reales en dos dominios de aplicación: un servicio de información de autobuses de la Empresa Municipal de Transportes de Madrid y la recepción del Hotel Intur Palacio San Martín de Madrid. En la evaluación estuvieron implicadas personas sordas y empleados de los dos servicios. Se extrajeron medidas objetivas (obtenidas por el sistema automáticamente) y subjetivas (mediante cuestionarios a los usuarios). Los resultados fueron muy positivos gracias a la opinión de los usuarios de la evaluación, que validaron el funcionamiento del sistema de traducción y dieron información valiosa para futuras líneas de trabajo. Por otro lado, tras la integración de cada uno de los módulos de los dos sistemas de traducción (habla-LSE y LSE-habla), los resultados de la evaluación y la experiencia adquirida en todo el proceso, una aportación importante de esta tesis doctoral es la propuesta de metodología de desarrollo de sistemas de traducción de habla a lengua de signos en los dos sentidos de la comunicación. En esta metodología se detallan los pasos a seguir para desarrollar el sistema de traducción para un nuevo dominio de aplicación. Además, la metodología describe cómo diseñar cada uno de los módulos del sistema para mejorar su flexibilidad, de manera que resulte más sencillo adaptar el sistema desarrollado a un nuevo dominio de aplicación. Finalmente, en esta tesis se analizan algunas técnicas para seleccionar las frases de un corpus paralelo fuera de dominio para entrenar el modelo de traducción cuando se quieren traducir frases de un nuevo dominio de aplicación; así como técnicas para seleccionar qué frases del nuevo dominio resultan más interesantes que traduzcan los expertos en LSE para entrenar el modelo de traducción. El objetivo es conseguir una buena tasa de traducción con la menor cantidad posible de frases. ABSTRACT The main contribution of this thesis has been the proposal and evaluation of an automatic translation system for improving the communication between hearing and deaf people. This system is made up of two systems: a Spanish into Spanish Sign Language (LSE – Lengua de Signos Española) translator and a Spanish generator from LSE sign sequences. The first one consists of a speech recognizer, a language translation module and an avatar that represents the sign sequence. The second one is made up an interface for specifying the sign sequence, a language translation module and a text-to-speech conversor. For the translation system development, firstly, a parallel corpus has been generated with 7,696 Spanish sentences and their LSE translations. These sentences are related to four different application domains: the renewal of the Identity Document, the renewal of the driver license, a bus information service and a hotel reception. Moreover, a sign database has been generated with more than 1,000 signs described in four different signwriting systems. Secondly, it has been developed an automatic translation module that integrates two translation techniques in a hierarchical structure: the first one is a memory-based technique and the second one is statistical. Furthermore, a pre processing module for the Spanish sentences has been implemented. By incorporating this pre processing module into the statistical translation module, the accuracy of the translation module improves significantly. In this thesis, the LSE into speech translation interface has been improved. On the one hand, new characteristics that improve its usability have been incorporated and, on the other hand, a SMS language into Spanish translator has been integrated, that lets specifying in SMS language the sequence to translate, besides by specifying a sign sequence. The proposed translation system has been evaluated in two application domains: a bus information service of the Empresa Municipal de Transportes of Madrid and the Hotel Intur Palacio San Martín reception. This evaluation has involved both deaf people and services employees. Objective measurements (given automatically by the system) and subjective measurements (given by user questionnaires) were extracted during the evaluation. Results have been very positive, thanks to the user opinions during the evaluation that validated the system performance and gave important information for future work. Finally, after the integration of each module of the two translation systems (speech- LSE and LSE-speech), obtaining the evaluation results and considering the experience throughout the process, a methodology for developing speech into sign language (and vice versa) into a new domain has been proposed in this thesis. This methodology includes the steps to follow for developing the translation system in a new application domain. Moreover, this methodology proposes the way to improve the flexibility of each system module, so that the adaptation of the system to a new application domain can be easier. On the other hand, some techniques are analyzed for selecting the out-of-domain parallel corpus sentences in order to train the translation module in a new domain; as well as techniques for selecting which in-domain sentences are more interesting for translating them (by LSE experts) in order to train the translation model.

Pre-service teacher education and the development of middle school teacher identity : an exploratory study

This research study investigated the factors that influenced the development of teacher identity in a small cohort of mature-aged graduate pre-service teachers over the course of a one-year Graduate Diploma program (Middle Years). It sought to illuminate the social and relational dynamics of these pre-service teachers’ experiences as they began new ways of being and learning during a newly introduced one-year Graduate Diploma program. A relational-ontological perspective underpinned the relational-cultural framework that was applied in a workshop program as an integral part of this research. A relational-ontological perspective suggests that the development of teacher identity is to be construed more as an ontological process than an epistemological one. Its focus is more on questions surrounding the person and their ‘becoming’ a teacher than about the knowledge they have or will come to have. Hence, drawing on work by researchers such as Alsup (2006), Gilligan, (1982), Isaacs, (2007), Miller (1976), Noddings, (2005), Stout (2001), and Taylor, (1989), teacher identity was defined as an individual pre-service teacher’s unique sense of self as a teacher that included his or her beliefs about teaching and learning (Alsup, 2006; Stout, 2001; Walkington, 2005). Case-study was the preferred methodology within which this research project was framed, and narrative research was used as a method to document the way teacher identity was shaped and negotiated in discursive environments such as teacher education programs, prior experiences, classroom settings and the practicum. The data that was collected included student narratives, student email written reflections, and focus group dialogue. The narrative approach applied in this research context provided the depth of data needed to understand the nature of the mature-aged pre-service teachers’ emerging teacher identities and experiences in the graduate diploma program. Findings indicated that most of the mature-aged graduate pre-service teachers came in to the one-year graduate diploma program with a strong sense of personal and professional selves and well-established reasons why they had chosen to teach Middle Years. Their choice of program involved an expectation of support and welcome to a middle-school community and culture. Two critical issues that emerged from the pre-service teachers’ narratives were the importance they placed on the human support including the affirmation of themselves and their emerging teacher identities. Evidence from this study suggests that the lack of recognition of preservice teachers’ personal and professional selves during the graduate diploma program inhibited the development of a positive middle-school teacher identity. However, a workshop program developed for the participants in this research and addressing a range of practical concerns to beginning teachers offered them a space where they felt both a sense of belonging to a community and where their thoughts and beliefs were recognized and valued. Thus, the workshops provided participants with the positive social and relational dynamics necessary to support them in their developing teacher identities. The overall findings of this research study strongly indicate a need for a relational support structure based on a relational-ontological perspective to be built into the overall course structure of Graduate Pre-service Diplomas in Education to support the development of teacher identity. Such a support structure acknowledges that the pre-service teacher’s learning and formation is socially embedded, relational, and a continual, lifelong process.

QUT Speaker Identity Verification system for EVALITA 2009

This document outlines the system submitted by the Speech and Audio Research Laboratory at the Queensland University of Technology (QUT) for the Speaker Identity Verification: Application task of EVALITA 2009. This competitive submission consisted of a score-level fusion of three component systems; a joint-factor analysis GMM system and two SVM systems using GLDS and GMM supervector kernels. Development evaluation and post-submission results are presented in this study, demonstrating the effectiveness of this fused system approach. This study highlights the challenges associated with system calibration from limited development data and that mismatch between training and testing conditions continues to be a major source of error in speaker verification technology.

The influence of conformity and group identity on drink walking intentions : comparing intentions to drink walk across risky pedestrian crossing scenarios

Despite the dangers associated with drink walking, limited research is currently available regarding the factors which influence individuals to engage in this risky behaviour. This study examined the influence of psychosocial factors upon individuals’ intentions to drink walk across four experimental scenarios (and a control condition). Specifically, a 2 × 2 repeated measures design was utilised in which all of the scenarios incorporated a risky pedestrian crossing situation (i.e., a pedestrian crossing against a red man signal) but differed according to the level of group identity (i.e., low/strangers and high/friends) and conformity (low and high). Individuals were assessed for their intentions to drink walk within each of these different scenarios. Undergraduate students (N = 151), aged 17–30 years, completed a questionnaire. Overall, most of the study's hypotheses were supported with individuals reporting the highest intentions to drink walk when in the presence of friends (i.e., high group identity) and their friends were said to be also crossing against the red man signal (i.e., high conformity). The findings may have significant implications for the design of countermeasures to reduce drink walking. For instance, the current findings would suggest that potentially effective strategies may be to promote resilience to peer influence as well as highlight the negative consequences associated with following the behaviour of other intoxicated pedestrians who are crossing against a red signal.

Peer passenger identity and passenger pressure on young drivers' speeding intentions

Young drivers, aged 17 to 24 years, have the highest fatality rate in Australia. It is believed that part of this risk is due to pressure from peer passengers to engage in speeding; which may be active (i.e., verbal encouragement) or passive (i.e., perceived pressure on the part of the driver). The Theory of Planned Behaviour (TPB) was used to investigate this impact of peer passengers on young drivers, particularly the influence of the type of peer pressure and a driver’s level of identification with their passengers. A scenario-based questionnaire was constructed, informed by focus groups and pilot studies, and distributed to university students (N = 398). The questionnaire measured participants’ intentions and the TPB constructs, including two components of perceived behaviour control, within a baseline scenario as well as an experimental scenario in which the variables of type of pressure and identification were manipulated. Consistent with the hypotheses, the study found that attitudes and self-efficacy significantly predicted intentions over and above the variance explained by the sociodemographic variables of age, gender, self-esteem, sensation seeking, as well as past behaviour and exposure. Across the scenarios, attitudes explained between 4.3% and 14.5%, while self-efficacy to refrain from speeding explained between 4.9% and 17.1%, of the unique variance in intentions to speed. However, contrary to expectations, intentions to speed were found to be higher in the “no passenger” than “passenger present” conditions, although this finding is not completely inconsistent with recent literature. A high level of identification with passengers led to higher intentions to speed than low identification as expected, but, inconsistent with expectations, different types of pressure (i.e., active versus passive) did not influence intentions to speed.

'My grandchild has a disability' : impact on grandparenting identity, roles and relationships

Being a grandparent is an important and valued role for many older adults, who often have strong views about the type of grandparent they will be and what they will teach their grandchild. When their grandchild has a disability, grandparents may have to significantly adjust their expectations and interactions. This research explores if and how having a grandchild with a disability influences grandparents’ sense of identity and enactment of the grandparent role. Using qualitative purposive sampling, semi-structured interviews were conducted with 22 grandparents of children with an intellectual and/or physical disability residing in Brisbane, Australia. A thematic analysis identified three key themes characterising grandparent’s views: formation of grandparenting identity, styles of grandparenting, and role enactment. The results highlight the critical role of grandparents when a child has a disability, illustrating that the grandparenting experience and role enactment may be universal with only the context and delivery varying.

The construction of social identity in newly recruited nuclear engineering staff : a longitudinal study

This study examines the process by which newly recruited nuclear engineering and technical staff came to understand, define, think, feel and behave within a distinct group that has a direct contribution to the organization's overall emphasis on a culture of reliability and system safety. In the field of organizational behavior the interactive model of social identity formation has been recently proposed to explain the process by which the internalization of shared norms and values occurs, an element critical in identity formation. Using this rich model of organizational behavior we analyzed multiple sources of data from nine new hires over a period of three years. This was done from the time they were employed to investigate the construction of social identity by new entrants entering into a complex organizational setting reflected in the context of a nuclear facility. Informed by our data analyses, we found support for the interactive model of social identity development and report the unexpected finding that a newly appointed member's age and level of experience appears to influence the manner in which they adapt, and assimilate into their surroundings. This study represents an important contribution to the safety and reliability literature as it provides a rich insight into the way newly recruited employees enact the process by which their identities are formed and hence act, particularly under conditions of duress or significant organizational disruption in complex organizational settings.
