The co-emergence of Spanish as a second language and individual differences : a dynamical systems theory perspectiveLyle, Cory Jackson 19 July 2012 (has links)
Dynamical Systems Theory (DST) (De Bot, Lowie, & Vespoor 2007; Larsen-Freeman 1997, 2007; Larsen-Freeman & Cameron 2008; Dörnyei 2009; and van Lier 2000) represents a scientific paradigm shift derived from the fields of physics, engineering and theoretical mathematics that attempts to solve real-world scenarios that do not respond to scientific reductionism, otherwise known as ‘analysis’. The purpose of this dissertation is to (re)frame foreign language learning/use as a dynamical process that that involves interplay among what Dörnyei (2009) terms the language, the agent and the environment. More specifically, this dissertation presents a quasi-experimental, psycholinguistic study that looks at the interface between language (in this case the talk that resulted from NS-NNS interactions) and agent (as defined by a set of personal traits, or Individual Differences [IDs], including motivation, attitudes, personality and aptitude) in order to answer the research question: Do IDs vary in conjunction with language learning/use, and if so, how?
Eight tutored Spanish learners were followed over the course of 16 weeks during which time they participated in 8 chat sessions with a native Spanish-speaker. Their ID profiles were measured immediately before and after each session and sessions with significant pre- to post-session ID shifts were analyzed to determine to what extent such shifts correlated with certain types of talk and/or think-aloud sequences.
Results indicated that all participants’ pre- and post-interactional ID profiles fluctuated measurably and significantly, even within the span of a single interaction. Moreover, those sessions with significantly positive ID shifts were qualitatively different in terms of language-related episodes (LREs), conversation management/pragmatic markers, and metacognition from those with significantly negative ID shifts. Other unexpected findings revealed, for example, that LREs (especially NS-initiated LREs) negatively impacted motivations and attitudes and, therefore, the language-learning process itself.
Taken together, the results of this study indicate that the agent’s IDs and their (inter)language co-emerge; that is to say, they evolve simultaneously and in response to one another. Moreover, this study suggests that DST can indeed be quasi-experimentally applied to the study of SLA, thus necessitating further development in DST-oriented methodologies and research questions. / text

Mental health diagnoses in persons with an intellectual disability : how health practitioners overcome the challenges.Davies, Karen Patricia January 2015 (has links)
Legislative changes in line with changing societal perspectives have resulted in increased service pressure on primary health practitioners to take further responsibility for the assessment and treatment of co-morbid psychiatric disorders in individuals with intellectual disability (ID) and for secondary and tertiary level services to reduce waitlists. The unique attributes of the ID population and a core lack of training for health professionals in the ID field has resulted in a large number of practitioners feeling under-trained and under-resourced to carry out this role effectively, to the potential detriment of the ID population. The challenges health practitioners experience when diagnosing co-morbid mental health disorders in individuals with ID and how they overcome these challenges was explored in this study. Participants were health practitioners of varying professions, including Psychiatrists, Clinical Psychologists and General Practitioners. Health practitioners completed an online survey and/or partook in a focus group or individual interview. The method used in this research was thematic analysis. The study found that health practitioners use holistic and contextual approaches to carry out assessments of individuals with ID, utilise ID specific tools, and liaise with experienced, specialised health practitioners as ways of dealing with the complexity of diagnosing co-morbid mental health difficulties in individuals with ID. In addition, it is recommended that more training in the ID area is provided for health practitioners, particularly for GPs in light of recent policy changes with emphasis of assessment and treatment occurring at the primary health level and for best practice guidelines to be developed. A further research project is suggested, exploring specific challenges facing GPs in this area of practice.

ID TROUBLES: The National Identification Systems in Japan and the (mis) Construction of the SubjectOgasawara, Midori 30 May 2008 (has links)
Modern Japan established three kinds of national identification (ID) systems over its population: Koseki, Alien Registration, and Juki-net. The Koseki system is a patriarchal family registration of all citizens. It began in the 1870s when Japan’s nation-state was developed under the emperor’s rule. Koseki used traditional patriarchal hierarchy and loyalty to construct subjects for the Japanese Empire and reify a fictional unity among the “Japanese” people. Until today, this disciplinary element has functioned as the norm for organizational relations in Japan.
The Alien Registration System requires non-citizens to register and carry an ID card to distinguish “foreigners” from “Japanese”. This system stems from surveillance techniques used over the colonial populations in the early twentieth century: the Chinese in the colony of “Manchuria”, in northeast China, and the Koreans on the Japanese mainland. Although the empire collapsed after World War II, the practice was officially legislated to target Koreans and Chinese who remained in post-war democratic Japan.
Juki-net is the recently established computer network for sharing the personal data of citizens between government and municipal authorities. Juki-net attaches a unitary ID number to all citizens and gives them an optional ID card. Juki-net uses digital technology to capture individual movement, so the system is direct, individualistic, and fluid. It has expanded the scope of personal data and shifts the foundation of citizenship to state intervention.
This thesis examines how these three systems have defined the boundary of the nation and constructed categories for its subjects, which have then been imposed on the entire population. Drawing on the theories of Foucault’s bio-power and Agamben’s bare life, I explain how the national ID card systems enable the state to include and exclude people, use them for its own power, and produce subjects to support the state. Although this process is often hidden, the scheme is a vital part of the current proposal to use national ID card systems in the global “war on terror”. I argue that the national ID card systems impose compulsory classifications on individuals, threaten the public’s rights against state intervention, and spread “bare life” across the population. / Thesis (Master, Sociology) -- Queen's University, 2008-05-29 13:58:26.233

Integral-Based Inverse Problem Solutions for DIET SystemsHoughton, Samuel January 2007 (has links)
Magnetic Resonance Elastography (MRE) is an emerging method for non-invasive breast cancer screening. It takes the MRI displacement data output and reconstructs the internal stiffness distribution, where cancerous tissue is approximately five to ten times stiffer than healthy breast tissue. Hence, MRE offers a high contrast solution to this diagnostic problem. Current MRE methods for reconstructing stiffness use forward simulation based optimization methods that are highly non-linear, non-convex and very heavy computationally. This research develops integral-based inverse problem solutions that reformulate the underlying differential equations in terms of integrals of MRI measured displacement data, and this transforms the problem into a linear, convex optimization. All derivative terms in the formulation are removed by special choice of integration limits, so no smoothing or filtering of the input data is required. The resulting equations can easily be solved by linear least squares requiring very minimal computation. 1D inverse algorithms were developed to provide a proof of concept of the integral-based method. Initially, the complete compressible 2D Navier's equations were used to develop the 2D inverse methods. Reasonable results were achieved with the algorithm successfully identifying a 1cm by 1cm tumour with up to 10% noise, data resolution of 20 measured points per cm and actuation frequencies of 100Hz. However, for the same input data set, a simplified incompressible 2D model was used as the basis for the final proposed inverse algorithm. This approach significantly improved results by removing ill-conditioned terms from the original formulation. For a 1cm by 1 cm tumour, accurate results were obtained with up to 40% noise, a range of actuation frequencies and very low data resolution of the order of 2 measured points per cm. These results thus indicate that more crude and less expensive data measurement systems could be used to obtain good results. The methods developed can be readily extended to 3D by applying a similar incompressible integral formulation to the 3D Navier's equations.

Iterative receiver in multiuser relaying systems with fast frequency-hopping modulation2013 August 1900 (has links)
In this thesis, a novel iterative receiver and its improved version are proposed for
relay-assisted multiuser communications, in which multiple users transmit to a destination
with the help of a relay and using fast frequency-hopping modulation. Each
user employs a channel encoder to protect its information and facilitate interference
cancellation at the receiver. The signal received at the relay is either amplified, or
partially decoded with a simple energy detector, before being forwarded to the destination.
Under flat Rayleigh fading channels, the receiver at the destination can
be implemented non-coherently, i.e., it does not require the instantaneous channel
information to demodulate the users’ transmitted signals. The proposed iterative
algorithm at the destination exploits the soft outputs of the channel decoders to
successively extract the maximum likelihood symbols of the users and perform interference
cancellation. The iterative method is successfully applied for both cases of
amplify-and-forward and partial decode-and-forward relaying. The error performance
of the proposed iterative receiver is investigated by computer simulation. Under the
same spectral efficiency, simulation results demonstrate the excellent performance of
the proposed receiver when compared to the performance of decoding without interference
cancellation as well as the performance of the maximum likelihood multiuser
detection previously developed for uncoded transmission. Simulation results also suggest
that a proper selection of channel coding schemes can help to support significant
more users without consuming extra system resources.
In addition, to further enhance the receiver’s performance in terms of the bit error
rate, an improved version of the iterative receiver is presented. Such an improved receiver
invokes inner-loop iterations between the channel decoders and the demappers
in such a way that the soft outputs of the channel decoders are also used to refine the
outputs of the demappers for every outer-loop iteration. Simulation results indicate
a performance gain of about 2.5dB by using the two-loop receiver when compared to
the performance of the first proposed receiver.

Evaluation of Different Radio-Based Indoor Positioning MethodsAhlberg, Sven January 2014 (has links)
Today, positioning with GPS and the advantages this entails are almost infinitive, which means that the technology can be utilized in a variety of applications. Unfortunately, there exists a lot of limitations in conjunction with the signals from the GPS can’t reach inside e.g. buildings or underground. This means that an alternative solution that works indoors needs to be developed. The report presents the four most common radio-based technologies, Bluetooth,Wi-Fi, UWB and RFID, which can be used to determine a position. These all have different advantages in cost, accuracy and latency, which means that there exist a number of different applications. The radio-based methods use the measurement techniques, RSSI, TOA, TDOA, Cell-ID, PD or AOA to gather data. The choice of measurement technique is mainly dependent of which radio-based method being used, since their accuracy depends on the quality of the measurements and the size of the detection area, which means that all measurement techniques have different advantages and disadvantages. The measurement data is processed with one of the positioning methods, LS, NLS, ML, Cell-ID, WC or FP, to estimate a position. The choice of positioning method also depends on the quality of the measurements in combination with the size of the detection area. To evaluate the different radio-based methods together with measurement techniques and positioning methods, accuracy, latency and cost are being compared. This is used as the basis for the choice of positioning method, since a general solution can get summarized by finding the least expensive approach which can estimate an unknown position with sufficiently high accuracy.
