Identity formation and public perception in the history of American Mormonism

This study inquires into the institutional identity of the Church of Jesus Christ of Latter-day Saints since its founding in 1830. The study takes a historical stance in discussing the relationship between American public perceptions and the Church's developing internal identity, tracing these changes through three distinct historical stages. Building on the works of historians and sociologists such as Jan Shipps, Armand Mauss, and Terryl Givens, this study hopes to contribute to the understanding of new religious movements and the progression from sect to church. The study finds that Mormon identity and American perceptions of Mormons have had an inter-influential relationship, each responding and re-forming in turn. The LDS Church has progressed from sect to church as tensions with the host society have lessened. Currently, the Church is at an optimum level of tension with the host society, maintaining a distinct identity while enjoying conventional acceptance.

Identity Change Impacts Autobiographical Reconstruction of Identity-Relevant Events: Influences of the Self-System on Remembering

The focus on how one is behaving, feeling, and thinking, provides a powerful source of self-knowledge. How is this self-knowledge utilized in the dynamic reconstruction of autobiographical memories? How, in turn, might autobiographical memories support identity and the self-system? I address these questions through a critical review of the literature on autobiographical memory and the self-system, with a special focus on the self-concept, self-knowledge, and identity. I then outline the methods and results of a prospective longitudinal study examining the effects of an identity change on memory for events related to that identity. Participant-rated memory characteristics, computer-generated ratings of narrative content and structure, and neutral-observer ratings of coherence were examined for changes over time related to an identity-change, as well as for their ability to predict an identity-change. The conclusions from this study are threefold: (1) when the rated centrality of an event decreases, the reported instances of retrieval, as well as the phenomenology associated with retrieval and the number of words used to describe the memory, also decrease; (2) memory accuracy (here, estimating past behaviors) was not influenced by an identity change; and (3) remembering is not unidirectional – characteristics of identity-relevant memories and the life story predict and may help support persistence with an identity (here, an academic trajectory).

Who Do You Say I Am?: African American Women Clergy and the Construction of Ministerial Identity

The purpose of this study was to examine how African American women in ordained ministry construct and develop ministerial identity in the context of the Black Church. This study employed a qualitative multicase study methodology and the purposive participant sample was comprised of 13 women who were ordained or pursuing ordination in the Baltimore or Washington conferences of the AME Church. Semistructured in-depth interviews were conducted with the participants, and member checks were employed as a triangulation method. This study reveals that the primary factor impacting ministerial identity development is the relationship with the senior pastor and explores the various ways in which that impact is felt. This study also connects aspects of that relationship and its resulting impact to African American cultural traditions and values, as well as offers several suggestions to women cultivating ministerial identity and the organizational systems within which that process occurs.

Identity, Purpose, and Well-Being Among Emerging Adult Hispanic Women

Few studies apply the Eriksonian model of identity formation to cross-cultural samples (3), even though issues of ethnicity and culture may inform a Hispanic woman’s self-concept (Phinney, 1996). Hispanic women may also be influenced by traditional gender role behaviors such as passivity or dependence that are outlined by marianismo (Stevens, 1973). A recent study of a multiethnic sample of emerging adult women and men found that purpose commitment mediated the effects of identity commitment on hope and life satisfaction (Burrow & Hill, 2011). The current research consists of two studies that replicate and expand upon the work of Burrow and Hill (2011). Study I replicated the work of Burrow and Hill (2011) among a sample of emerging adult Hispanic women, in order to assess the extent to which the original findings would replicate in a culturally distinct sample. Study II examined the role of marianismo, ethnic identity, and acculturation on identity commitment among emerging adult Hispanic women. Both studies utilized a sample of 532 female undergraduate psychology students, age 18 to 25, who self-identified as Hispanic and submitted data via online surveys. Both studies used self-report, quantitative data, which was analyzed using structural equation modeling. Results from Study I indicated good model fit and replicated the findings from Burrow and Hill (2011). Specifically, the direct effect of identity commitment on hope was fully contingent upon an individual’s level of purpose commitment, while the effect of identity commitment on life satisfaction was not contingent upon an individual’s level of purpose commitment. Results from Study II indicated that marianismo, Spanish proficiency, familiarity with Latino culture, and familiarity with American culture demonstrated statistically significant direct effects on identity commitment among emerging adult Hispanic women. Results indicated cultural convergence regarding the association of an individual’s identity with well-being through a sense of purpose. Findings also revealed the role of cultural factors in the extent to which Hispanic women commit to a personal identity. Future studies should employ mixed method research designs as a means to better ascertain implications of findings.

Time-dependency of Rocks and Implications Associated with Tunnelling

The formulation of a geotechnical model and the associated prediction of the mechanical behaviour is a challenge engineers need to overcome in order to optimize tunnel design and meet project requirements. Special challenges arise in cases where rocks and rockmasses are susceptible to time-effects and time-dependent processes govern. Progressive rockmass deformation and instability, time-dependent overloading of support and delayed failures are commonly the result of time-dependent phenomena. The research work presented in this thesis serves as an attempt to provide more insight into the time-dependent behaviour of rocks. Emphasis is given on investigating and analyzing creep deformation and time-dependent stress relaxation phenomenon at the laboratory scale and in-depth analyses are presented. This thesis further develops the understanding of these phenomena and practical yet scientific tools for estimating and predicting the long-term strength and the maximum stress relaxation of rock materials are proposed. The identification of the existence of three distinct behavioural stages during stress relaxation is presented and discussed. The main observations associated with time-dependent behaviour are employed in numerical analyses and applied at the tunnel scale. A new approach for simulating and capturing the time-dependent behaviour coupled with the tunnel advancement effect is also developed and analyzed. Guidance is provided to increase the understanding of the support-rockmass interaction and the main implications and significance of time-dependent behaviour associated with rock tunnelling are discussed. The work presented in this thesis advances the scientific understanding of time-dependent rock and rockmass behaviour, increases the awareness of how such phenomena are captured numerically, and lays out a framework for dealing with such deformations when predicting tunnel deformations. Practical aspects of this thesis are also presented, which will increase their usage in the associated industries and close the gap between the scientific and industry communities.

Nagaland: Borders, Boundaries, Belonging: Contested spaces and disputed narratives

In 2011 I travelled to three of the ‘Seven Sister’ states of old Assam, Nagaland, Meghalaya & Assam. My journey to this remote and politically sensitive region, bordering Chinese occupied Tibet, Bangladesh and Myanmar was prompted by my father’s experiences in the region during WW2 in the Burma Campaign and brought into sharp relief on-going themes in my work, the impact the past has on the present, the relationship of time and place, identity and memory and the transcultural experiences caused by war, colonisation and migration. The drawings I made on location, the objects I collected and the notes and photographs I took formed the basis of the bookwork: NAGALAND borders boundaries belonging. When making the finished work the material quality of the object and the processes by which it was made become very important. The historical resonance of the medium and the time consuming nature of the process reflect the embedding of form and idea, and paid homage to the material culture of the Naga hill tribes. The bookwork was hand-bound, handset and printed by letterpress. Some spreads were printed in 6 colours and the book took over a year to produce. I see my practice as echoing that of generations of Lady travellers; embracing the need to journey, be in a liminal space, to have a plan but not be afraid to divert from it. To be alone, take a sketchbook and make images is, for me, the definition of the itinerant illustrator; one who travels widely in geographic space, visual forms and ideas, in order to get lost and find the unlooked for.

Design and implementation of generalized topologies of time-interleaved variable bandpass Σ−Δ modulators

In this thesis, novel analog-to-digital and digital-to-analog generalized time-interleaved variable bandpass sigma-delta modulators are designed, analysed, evaluated and implemented that are suitable for high performance data conversion for a broad-spectrum of applications. These generalized time-interleaved variable bandpass sigma-delta modulators can perform noise-shaping for any centre frequency from DC to Nyquist. The proposed topologies are well-suited for Butterworth, Chebyshev, inverse-Chebyshev and elliptical filters, where designers have the flexibility of specifying the centre frequency, bandwidth as well as the passband and stopband attenuation parameters. The application of the time-interleaving approach, in combination with these bandpass loop-filters, not only overcomes the limitations that are associated with conventional and mid-band resonator-based bandpass sigma-delta modulators, but also offers an elegant means to increase the conversion bandwidth, thereby relaxing the need to use faster or higher-order sigma-delta modulators. A step-by-step design technique has been developed for the design of time-interleaved variable bandpass sigma-delta modulators. Using this technique, an assortment of lower- and higher-order single- and multi-path generalized A/D variable bandpass sigma-delta modulators were designed, evaluated and compared in terms of their signal-to-noise ratios, hardware complexity, stability, tonality and sensitivity for ideal and non-ideal topologies. Extensive behavioural-level simulations verified that one of the proposed topologies not only used fewer coefficients but also exhibited greater robustness to non-idealties. Furthermore, second-, fourth- and sixth-order single- and multi-path digital variable bandpass digital sigma-delta modulators are designed using this technique. The mathematical modelling and evaluation of tones caused by the finite wordlengths of these digital multi-path sigmadelta modulators, when excited by sinusoidal input signals, are also derived from first principles and verified using simulation and experimental results. The fourth-order digital variable-band sigma-delta modulator topologies are implemented in VHDL and synthesized on Xilinx® SpartanTM-3 Development Kit using fixed-point arithmetic. Circuit outputs were taken via RS232 connection provided on the FPGA board and evaluated using MATLAB routines developed by the author. These routines included the decimation process as well. The experiments undertaken by the author further validated the design methodology presented in the work. In addition, a novel tunable and reconfigurable second-order variable bandpass sigma-delta modulator has been designed and evaluated at the behavioural-level. This topology offers a flexible set of choices for designers and can operate either in single- or dual-mode enabling multi-band implementations on a single digital variable bandpass sigma-delta modulator. This work is also supported by a novel user-friendly design and evaluation tool that has been developed in MATLAB/Simulink that can speed-up the design, evaluation and comparison of analog and digital single-stage and time-interleaved variable bandpass sigma-delta modulators. This tool enables the user to specify the conversion type, topology, loop-filter type, path number and oversampling ratio.

Gender, Nationality and Cultural Representations of Ireland: An Irish Woman's Place?

Ireland has struggled with its ‘feminine’ identity throughout its history. The so-called ‘chasmic dichotomy of male and female' is embedded in colonial and postcolonial constructions of Irishness and it continues to manifest itself in contemporary cultural representations of Ireland and Irishness. This study explores issues of gender and nationality via a reading of a 70-second television advertisement for Caffrey's Irish Ale, titled ‘New York’. The article suggests that, although colonial and postcolonial discourse on Ireland continues to perceive the ‘feminine’ in problematic terms, this is gradually changing as Irish women increasingly, in poet Eavan Boland's words, ‘open a window on those silences, those false pastorals, those ornamental reductions’ that have confined us.

Near-real-time service provision during effusive crises at Etna and Stromboli: basis and implementation of satellite-based IR operations

Using the NEODAAS-Dundee AVHRR receiving station (Scotland), NEODAAS-Plymouth can provide calibrated brightness temperature data to end users or interim users in near-real time. Between 2000 and 2009 these data were used to undertake volcano hot spot detection, reporting and time-average discharge rate dissemination during effusive crises at Mount Etna and Stromboli (Italy). Data were passed via FTP, within an hour of image generation, to the hot spot detection system maintained at Hawaii Institute of Geophysics and Planetology (HIGP, University of Hawaii at Manoa, Honolulu, USA). Final product generation and quality control were completed manually at HIGP once a day, so as to provide information to onsite monitoring agencies for their incorporation into daily reporting duties to Italian Civil Protection. We here describe the processing and dissemination chain, which was designed so as to provide timely, useable, quality-controlled and relevant information for ‘one voice’ reporting by the responsible monitoring agencies.
