description: The purpose of the present thesis was two-fold. First, to evaluate the impact of cognitive demand on postural control in young adults and second, to examine the responsiveness of postural control to cognitive tasks presented in varying modalities. Seventeen young adults stood on a force platform while simultaneously performing cognitive tasks of varying difficulty (easy, moderate and difficult), each presented auditorily and visually. Performing the moderate and difficult tasks precipitated a greater reduction in area of 95% confidence ellipse and medio-lateral (ML) sway variability compared to the easy tasks. Presenting the tasks visually produced lower ML sway variability than presenting the tasks auditorily. Of secondary interest of this thesis was to determine if the duration of inter-stimulus intervals could modify the effectiveness of a cognitive task on postural control. Participants stood on a force platform while simultaneously performing cognitive tasks with five-second inter-stimulus intervals (i.e. discrete) and two-second inter-stimulus intervals (i.e. continuous), each presented auditorily and visually. Results revealed higher anterior-posterior (AP) mean power frequency (MPF) when performing the continuous tasks. In addition, presented the tasks visually resulted in a greater reduction in area of 95% confidence ellipse, AP and ML sway variability.

description: We search for emergent hydrodynamic modes in real-time Hamiltonian dynamics of $2+1$-dimensional SU(2) lattice gauge theory on a quasi one dimensional plaquette chain, by numerically computing symmetric correlation functions of energy densities on lattice sizes of about $20$ with the local Hilbert space truncated at $j_{\rm max}=\frac{1}{2}$. Because of the Umklapp processes, we only find a mode for energy diffusion. The symmetric correlator exhibits transport peak near zero frequency with a width approximately proportional to momentum squared at small momentum, when the system is fully quantum ergodic, as indicated by the eigenenergy level statistics. This transport peak leads to a power-law $t^{-\frac{1}{2}}$ decay of the symmetric correlator at late time, also known as the long-time tail, as well as diffusion-like spreading in position space. We also introduce a quantum algorithm for computing the symmetric correlator on a quantum computer and find it gives results consistent with exact diagonalization when tested on the IBM emulator. Finally we discuss the future prospect of searching for the sound modes.

Publisher: name: Routledge
Year: 2020

description: Preparation of archaeological data for spatial analysis and the documentation of these procedures is now seen as key for effective management, analysis, interpretation and potential re-use of digital archaeological data. In an era of more user-friendly cyber-infrastructures in the field of archaeology, and with growing interest in the integration of information from diverse sources, greater efforts are now made to consider the quality of archaeological data, how best to document workflows and versions, as well as facilitate collaborative research. This chapter presents an overview of these issues, and offers guidelines and best practices in terms of scripted workflows, version control for managing data and open and collaborative research in archaeological spatial analysis.

description: In the era of the James Webb Space Telescope (JWST), the dramatic improvement in the spectra of exoplanetary atmospheres demands a corresponding leap forward in our ability to analyze them: atmospheric retrievals need to be performed on thousands of spectra, applying to each large ensembles of models (that explore atmospheric chemistry, thermal profiles and cloud models) to identify the best one(s). In this limit, traditional Bayesian inference methods such as nested sampling become prohibitively expensive. We introduce FASTER (Fast Amortized Simulation-based Transiting Exoplanet Retrieval), a neural-network based method for performing atmospheric retrieval and Bayesian model comparison at a fraction of the computational cost of classical techniques. We demonstrate that the marginal posterior distributions of all parameters within a model as well as the posterior probabilities of the models we consider match those computed using nested sampling both on mock spectra, and for the real NIRSpec PRISM spectrum of WASP-39b. The true power of the FASTER framework comes from its amortized nature, which allows the trained networks to perform practically instantaneous Bayesian inference and model comparison over ensembles of spectra -- real or simulated -- at minimal additional computational cost. This offers valuable insight into the expected results of model comparison (e.g., distinguishing cloudy from cloud-free and isothermal from non-isothermal models), as well as their dependence on the underlying parameters, which is computationally unfeasible with nested sampling. This approach will constitute as large a leap in spectral analysis as the original retrieval methods based on Markov Chain Monte Carlo have proven to be.

Collaborative knowledge management and the art of coaching: reflections on the diverse roles of the successful supervisor
Creators: name: Reidy, Jo

Publisher: name: Swinburne
Year: 2024

description: Throughout the past decade, university educators and educational policy makers in Australia have sought to understand and improve the policies and practices upon which research degrees have been founded. The changing context of the research training landscape has been examined and the role of the research supervisor has received increasing attention as far-reaching changes are made to policies, research imperatives and expanding research degree frameworks (Green 2003; Green and Usher 2003; Pearson and Cryer 2001). Research supervision is a complex activity in which the supervisor and the candidate embark on a journey together along seemingly separate, but inextricably entwined, pathways. This we all know. Those of us who supervise understand the complexities deeply: not only from our experiences as supervisors, but also as people who have been candidates in the past. Although the passing of time or our own research histories may make our own student experiences somewhat remote, they are still memorable and, according to the study by Lee and Williams (1999), continue to resonate, having a direct impact on the ways in which we supervise current research students. The need to consider the ways in which our own student experiences of supervision colour our supervisory practices is more imperative than ever given the context of higher education with respect to research degrees. This chapter seeks to look once again at supervision and supervisory practices, but from the viewpoint of an experienced supervisor (Green) and one of her successful doctoral candidates (Reidy), now ready to supervise doctorates for the first time. We consider briefly the current context in which our supervisory space resides, namely, higher education in Australia. Secondly, we look at supervision in terms of collaborative knowledge management. Thirdly, we move to critically reflect upon our own practices as supervisor and as supervisee and the journey that has taken us from coach and novice, mentor and mentee to friendly professional colleagues. In the chapter, we present some close-grained work based on interviews and the resulting transcripts. In doing so, we aim to generate further insights into supervision practices, the candidate’s journey and the strategies by which one can enrich the other, in the hope that readers might find some applicability to their own reflections upon their supervisory practices or their experiences as a candidate.
Factors Affecting Translational Efficiency of Bacteriophages

description: Mass production of translationally optimized bacteriophages (hereafter referred to as phages) is the need of the hour in the application of phages to therapy. Understanding translational efficiency of phages is the major preliminary step for mass producing efficient phages. The objective of this thesis is to understand factors affecting translational efficiency of phages. In chapter two, we hypothesized that weak translation initiation efficiency is responsible for weak codon concordance of Escherichia coli lambdoid phages with that of their hosts. We measured the strength of translation initiation using two indices namely minimum folding energy (MFE) and proportion of Shine-Dalgarno sequence (PSD). Empirical results substantiate our hypothesis suggesting lack of strong selection for improving codon adaptation in these phages is due to their weak translation initiation. In chapter three, we measured codon usage concordance between GC-rich and GC-poor Aeromonas phages with their GC-rich host Aeromonas salmonicida. We found low codon usage concordance in the GC-poor Aeromonas phages. We were interested in testing for the role of tRNAs in the GC-poor phages. We observed that the GC-poor phages carry tRNAs for codons that are overused by the phages and underused by the host. These findings suggest that the GC-poor Aeromonas phages carry their own tRNAs for compensating for the compositional difference between their genomes and that of their host. Previously several studies have reported observed avoidance of stable secondary structures in start site of mRNA in a wide range of species. We probed the genomes of 422 phage species and measured their secondary structure stability using MFE. We observed strong patterns of secondary structure avoidance (less negative MFE values) in the translation initiation region (TIR) and translation termination region (TTR) of all analyzed phages. These findings imply selection is operating at these translationally important sites to control stable secondary structures in order to maintain efficient translation.

description: Young adults often encounter challenges in career exploration. Self-guided interventions, such as the letter-exchange exercise, where participants envision and adopt the perspective of their future selves by exchanging letters with their envisioned future selves, can support career development. However, the broader adoption of such interventions may be limited without structured guidance. To address this, we integrated Large Language Model (LLM)-based agents that simulate participants' future selves into the letter-exchange exercise and evaluated their effectiveness. A one-week experiment (N=36) compared three conditions: (1) participants manually writing replies to themselves from the perspective of their future selves (baseline), (2) future-self agents generating letters to participants, and (3) future-self agents engaging in chat conversations with participants. Results indicated that exchanging letters with future-self agents enhanced participants' engagement during the exercise, while overall benefits of the intervention on future orientation, career self-concept, and psychological support remained comparable across conditions. We discuss design implications for AI-augmented interventions for supporting young adults' career exploration.

Engaging Health Care Professionals in Personalized Medicine: A Pilot Study Comparing Two Professional Engagement Approaches

Year: 2015
Subjects: Personalized Medicine
Professional engagement

description: Given the emerging importance of personalized medicine (PM) in primary care, now should be the ideal time for engaging with health care professionals (HCPs), both physicians and nurses, about integrating PM into practice. The question then becomes: what is the most effective way to engage with HCPs about emerging technologies that are not in routine clinical use and which are unfamiliar to many? The overall aim of this pilot study was to develop and compare two professional engagement (PE) approaches for engaging with HCPs about PM to inform their development and design of a future formal evaluation. The first PE intervention was a structured in-person focus group and the second was an online version, also incorporating an educational component, but without group interaction. The pilot study showed that while participants evaluated both interventions positively, the in-person workshop consistently scored higher; however, recruitment challenges were a major obstacle for this approach.

description: This thesis examines the reasons why certain Protestant churches in Taiwan during the martial law period advocated democratization, while others did not. It uses an institutional and organizational theory to better understand the inner workings of these churches to understand their norms and values in terms of their overall group culture. This is set against previous English-language research that focused primarily on the ideals of essentialized or reified religions, broadly defined, without looking at the variations that exist between different churches. It argues that in order to understand the actions of these churches towards democratization, we must look at the whole of each organization. The norms and values, on their own, are insufficient to explain their motivations.

description: Nitrogen-rich materials are of increasing interests for the development of a wide variety of applications. These compounds are prime candidates for ligands used in the complexation of metals since they possess several lone pairs. Resulting complexes have also exhibited a wide variety of interesting properties, ranging from magnetism to gas absorption to energetic properties. This thesis describes the synthesis and characterisation of new metallic complexes with the known energetic ligands: hydrazine and H3bta, as well as that of a new nitrogen-rich compound: H4ttp. Chapter 2 outlines a series of chains bridged by hydrazine and their potential as initiatory compounds. Mononuclear lanthanide H3bta complexes are presented in Chapter 3. The development of the new nitrogen-rich, tetrazole-based H4ttp ligand is described in Chapter 4. This new ligand was used to synthesise various lanthanide complexes through hydrothermal reactions.

High-order integration methods

description: The transient time-domain simulation, of the circuit response, is a fundamental component in the Computer-Aided Design tools of all integrated circuit and systems. It is typically desirable that a method adopted in the transient circuit simulator be of high- order and numerically stable. The two requirements, however, proved to be in conflict with each other, especially in the larger class of methods that were used in traditional circuit simulators. Recent work based on utilizing the Obreshkov formula has proved that it is possible to combine the high order with the numerical stability. The objective of this thesis is to show how the present implementation of the Obreshkov- based method can be improved and generalized to handle different types of circuits. The first aspect of improvement targets the computation of the high-order derivatives re- quired by the Obreshkov formula. The second aspect of improvement, presented in the thesis, develops a generalized formulation that takes into account the presence of non- linear memory elements, whose nonlinearity is based on a capacitive or inductive-based nonlinear model.

description: Après avoir publié, depuis 1985, une quarantaine d’ouvrages, Antoine Volodine est aujourd’hui reconnu comme l’un des écrivains français contemporains les plus importants. À preuve les nombreuses études qui lui ont été consacrées. Si donc plusieurs traits de son œuvre ont déjà été étudiés, il en est un qui, pourtant fondamental, n’a pas encore été abordé : les textes de l’auteur ne sont jamais signés de son orthonyme, de son nom réel, mais toujours publiés soit sous le nom d’Antoine Volodine — un pseudonyme —, soit sous la signature de plusieurs hétéronymes. Antoine Volodine et ses hétéronymes appartiennent également tous à la communauté des écrivains post-exotiques. Dans la première partie de ma thèse, j’explore les approches théoriques de la pseudonymie et de l’hétéronymie. J’examine ensuite le contenu donné à ces procédés par deux écrivains qui les ont pratiqués, Kierkegaard et Pessoa, puis je fais état des études qui ont analysé ces pratiques. J’ai mobilisé ainsi, parmi les théories du double, celles qui se rattachent plus à une scission qu’à une duplication du moi : théories psychanalytiques (Freud, Lacan) et anthropologiques (Girard). J’ai aussi exploité les notions deleuziennes de « personnage conceptuel » et de « déterritorialisation ». Dans une seconde partie, j’ai analysé quatre romans — Des anges mineurs (Volodine, 1999), Ilia Mouromietz et le rossignol brigand (E. Kronauer, 1999), Les aigles puent (L. Bassmann, 2010) et Onze rêves de suie (M. Draeger, 2010) —, ainsi que Le post-exotisme en dix leçons, leçon onze (1998), ouvrage « collectif » où est ébauchée l’esthétique d’une communauté d’écrivains. Dans le chapitre premier, j’ai repéré les différences présentes dans les œuvres signées par le pseudonyme et les divers hétéronymes afin de dégager les motivations sous-jacentes à cette pluralité d’écriture et les fins que celle-ci sert. Dans le second chapitre, j’ai exploré les ressemblances existant entre ces œuvres pour comprendre les raisons d’être de la communauté d’auteurs post-exotiques.

description: In recent years, machine learning potentials (MLPs) have become indispensable tools in physics, chemistry, and materials science, driving the development of software packages for molecular dynamics (MD) simulations and related applications. These packages, typically built on specific machine learning frameworks such as TensorFlow, PyTorch, or JAX, face integration challenges when advanced applications demand communication across different frameworks. The previous TensorFlow-based implementation of DeePMD-kit exemplified these limitations. In this work, we introduce DeePMD-kit version 3, a significant update featuring a multi-backend framework that supports TensorFlow, PyTorch, JAX, and PaddlePaddle backends, and demonstrate the versatility of this architecture through the integration of other MLPs packages and of Differentiable Molecular Force Field. This architecture allows seamless backend switching with minimal modifications, enabling users and developers to integrate DeePMD-kit with other packages using different machine learning frameworks. This innovation facilitates the development of more complex and interoperable workflows, paving the way for broader applications of MLPs in scientific research.

description: Cryptocurrencies fluctuate in markets with high price volatility, posing significant challenges for investors. To aid in informed decision-making, systems predicting cryptocurrency market movements have been developed, typically focusing on historical patterns. However, these methods often overlook three critical factors influencing market dynamics: 1) the macro investing environment, reflected in major cryptocurrency fluctuations affecting collaborative investor behaviors; 2) overall market sentiment, heavily influenced by news impacting investor strategies; and 3) technical indicators, offering insights into overbought or oversold conditions, momentum, and market trends, which are crucial for short-term price movements. This paper proposes a dual prediction mechanism that forecasts the next day's closing price by incorporating macroeconomic fluctuations, technical indicators, and individual cryptocurrency price changes. Additionally, a novel refinement mechanism enhances predictions through market sentiment-based rescaling and fusion. Experiments demonstrate that the proposed model achieves state-of-the-art performance, consistently outperforming ten comparison methods.

Unmet Self, Relational, and Spiritual Needs in Distressed Couple Relationships

Subjects: Needs

description: The present study investigated the unmet self, relational, and spiritual needs underlying distress in couple relationships. The study was framed in Object Relations Theory and Self Psychology and the literature on spirituality and spiritual needs. Self needs were defined as the need to be affirmed for one’s lovability and the need to be admired for one’s competence. Relational needs were defined as the need for connection, and the need to be autonomous and one’s own person, while at the same time remaining connected. Spiritual needs were defined as the need for purpose and meaning in life, the need to establish interdependence with others, the need for inner peace, and the need for transcendence. Participants were 73 heterosexual couples who had been married and/or living together in a committed relationship for at least five years. A quantitative / qualitative mixed method was used to gather the data using questionnaires and semi-structured interviews. From the 73 couples, eight high distress couples and eight low distress couples were selected for the analysis. Multivariate Analysis of Variance was used to test for group differences on unmet self, relational, and spiritual needs. Using all 73 couples, Regression Analysis was used to identify which of the unmet self, relational, and spiritual needs were predictors of distress. Using Giorgi’s Psychological Phenomenological Method, one high distress couple and one low distress couple from the 73 couples participated in a semi-structured interview. Results of the MANOVA suggest that high distress couples differ from low distress couples on the self need for lovability, the relational need for autonomy, and on all of the spiritual needs. Results of the Regression Analysis suggest that inner peace and transcendence are strong predictors of distress in couple relationships. Results of the qualitative analysis suggest that low distress couples are better able to empathize and respond to the needs of their partners while the high distress couples are unable to set their own needs aside in order to respond to the needs of their partner.

description: When it comes to monitoring human health, accuracy is not a choice. Accuracy in blood pressure (BP) estimation is essential for proper diagnosis and management of hypertension. An error of 5 mmHg is so serious, it can be responsible for doubling or halving number of patients diagnosed with hypertension. Motion artifacts are external sources of inaccuracy and can be due to sudden arm motion, muscle tremor, shivering, and transport vehicle vibration. Medium term drift, due to changing environmental factors, such as ambient temperature, can also contribute to the inaccuracy. Long term drift (ageing), can reach 9 mmHg during the first three months of usage. In this thesis, a new stage is added to current cuff based BP devices. This stage is responsible for adjusting the pressure reading before displaying it to end users. The proposed stage is provided with a 3-axis accelerometer, which makes the detection of motion artifacts during measurement possible. Moreover, it monitors changes in the ambient temperature and sensor ageing, so that it will adaptively compensate for these inaccuracies. These sources of inaccuracy are suppressed using algorithms based on Empirical Mode Decomposition (EMD), which has the feature of removing unwanted noise components little effect on the phase or the frequency distribution of the measured signal. With motion artifacts, measurements show that the proposed algorithms considerably improved the accuracy of the blood pressure estimates in comparison with the commonly-used conventional oscillometric algorithm that does not include a stage for artifact suppression, and allowed the estimates to consistent with the international ANSI/AAMI/ISO standard. Moreover, simulations based on experimental results show that the system is able to compensate for drift due to temperature changes and ageing with excellent performance. Results show promise towards building a robust BP monitor, with very low errors due to motion artifacts, environmental changes, and ageing.

description: Orbital resonances in extreme-mass-ratio inspirals (EMRIs) have been proven to be a key feature for accurate gravitational-wave template modeling. Decades of research have led to schemes that can not only model the adiabatic inspiral of such a binary system, but also account for the effects of resonances on their evolution. In this work, we use an effective resonance model that includes analytically derived corrections to the radiation reaction fluxes, to study the combined effects of both dominant (low-order) and subdominant (high-order) orbital resonances in EMRIs. We show that using single, universal shifts for all fluxes overestimates the resonance impact, and therefore individualized shifts for each resonance crossing are needed for accurate modeling. Our analysis reveals that the cumulative effects from multiple resonance crossings can significantly impact the orbital evolution of EMRIs, especially for highly eccentric orbits. Our results provide further evidence that resonance effects have to be included in template production to extract detailed astrophysical parameters from EMRI signals.

There is very little that Daniel Pauly writes that is not of interest to fisheries researchers, whether peer-reviewed or not. Such are the trials of a man whose lifetime of work has been so foundational in the fields of fisheries science and biodiversity research. We should all aspire to such tribulations. Here, Dr. Pauly pays homage two of his mentors, as well as with his colleagues sharing articles that range from marine biodiversity in the Indo-Pacific to fisheries management in the Small-Island States, from marine mammals in the Sea of Okhotsk to the Gill-Oxygen Limitation Theory (GOLT). The topics are widespread, but all are interesting, and I invite you to enjoy.

description: In this Master's Project I would like to propose a technique that will enable school learners of English as a Foreign Language to become more conversant with some structures which are seldom used in the students' active repertoire. By the time they reach "Seconde" (10th Grade) learners have been introduced to most intermediate and a good number of advanced structures of the English language. However, some of these structures are used by the students only passively, that is they are recognized only in reading or when they are heard. To reinforce the structures which they recognize as they read or as they are being spoken to, Krashen would recommend that the teacher continue exposing students to natural language for acquisition to occur. Personal experience, however, has shown that while some pupils can spontaneously become expert users of various grammar structures by simply being exposed to language, others need more scaffolding provided by the teacher for a longer period of time. In this paper, I will begin by analyzing five language approaches and methods. These are the Grammar-Translation Method, the Direct Method, the Audio-Lingual Method, Total Physical Response and the Natural Approach. To make a thorough analysis of each of these methods and approaches, I will make use of Richards and Rodgers (1986) model of investigation. We will then see how each of these approaches has influenced the Standard Oral Lessor, the most commonly used method in the Cote d'Ivoire. I feel a need to analyze the Standard Oral Lesson not so much because of the status it has been given in the Ivorian English language classes, but also because it is one lesson type that provides an opportunity for reactivation. At a later stage, I will try to perceive some limits of the reactivation technique. Subsequently, to this step I will attempt to provide some solutions to those limits.

description: Effective patient care requires interprofessional collaboration and decisions based on clinical guidelines. The goal of this study was to determine how interprofessional collaboration influences the introduction of nursing Best Practice Guidelines. This study was a secondary qualitative analysis of data obtained from interviews and reports from two selected sites (long term care and community health care) that demonstrated interprofessional collaboration during the introduction of nursing Best Practice Guidelines. Findings emphasized the importance of communication, the role of an interprofessional team, and the understanding of the roles of all involved in the introduction of discipline specific clinical guidelines. In addition, unregulated staff members were involved in leadership roles and their work was important in providing effective interprofessional collaborative care during the introduction of guidelines. Therefore, it is essential to appropriately involve all members of the interprofessional team, regardless of discipline or educational level, during the introduction of clinical guidelines.

description: In this thesis we deal with statistical inference related to extreme value phenomena. Specifically, if X is a random vector with values in d-dimensional space, our goal is to estimate moments of ψ(X) for a suitably chosen function ψ when the magnitude of X is big. We employ the powerful tool of regular variation for random variables, random vectors and time series to formally define the limiting quantities of interests and construct the estimators. We focus on three statistical estimation problems: (i) multivariate tail estimation for regularly varying random vectors, (ii) extremogram estimation for regularly varying time series, (iii) estimation of the expected shortfall given an extreme component under a conditional extreme value model. We establish asymptotic normality of estimators for each of the estimation problems. The theoretical findings are supported by simulation studies and the estimation procedures are applied to some financial data.
Visual space attention in three-dimensional space

description: Current models of visual spatial attention are based on the extent to which attention can be allocated in 2-dimensional displays. The distribution of attention in 3-dimensional space has received little consideration. A series of experiments were devised to explore the apparent inconsistencies in the literature pertaining to the allocation of spatial attention in the third dimension. A review of the literature attributed these inconsistencies to differences and limitations in the various methodologies employed, in addition to the use of differing attentional paradigms. An initial aim of this thesis was to develop a highly controlled novel adaptation of the conventional robust covert orienting of visual attention task (COVAT) in depth defined by either binocular (stereoscopic) or monocular cues. The results indicated that attentional selection in the COVAT is not allocated within a 3-dimensional representation of space. Consequently, an alternative measure of spatial attention in depth, the overlay interference task, was successfully validated in a different stereoscopic depth environment and then manipulated to further examine the allocation of attention in depth. Findings from the overlay interference experiments indicated that attentional selection is based on a representation that includes depth information, but only when an additional feature can aid 3D selection. Collectively, the results suggest a dissociation between two paradigms that are both purported to be measures of spatial attention. There appears to be a further dissociation between 2-dimensional and 3-dimensional attentional selection in both paradigms for different reasons. These behavioural results, combined with recent electrophysiological evidence suggest that the temporal constraints of the 3D COVAT paradigm result in early selection based predominantly on retinotopic spatial coordinates prior to the complete construction of a 3-dimensional representation. Task requirements of the 3D overlay interference paradigm, on the other hand, while not being restricted by temporal constraints, demand that attentional selection occurs later, after the construction of a 3-dimensional representation, but only with the guidance of a secondary feature. Regardless of whether attentional selection occurs early or late, however, some component of selection appears to be based on viewer-centred spatial coordinates.

description: The public acts of violence during the summer of 2012 in Toronto brought the theme of gangs back to the forefront in Canadian media coverage. As renewed debates argued old subject matters, our understanding of gangs was not able to diverge from its endless roundabout. This paper inverts the study of gangs that has classically looked towards the gang as a collective to explain its sub-cultural delinquent and sometimes violent tendencies, and explores the individualized interpretation of gang membership from the perspective of four Latin-Canadian males from the Greater Toronto Area. This study takes on the challenge of observing the trajectory of gang membership based on the first hand experiences of self-proclaimed ex-gang members and through an in-depth dialogue with these participants, ventures through the turning points that led these individual actors through the process of onset; commitment and desistance. This exploration into the lived experiences of gang membership is seen through a Symbolic Interactionist lens and views gang membership as one of many identities that can actively be portrayed by the social being. In this perspective, the concepts of gangs and gang membership are described as a subjective experience completely open to interpretation, but guided by the flow of unique interactions that these individuals encountered within a variety of complex situations and environments. That which is being observed herein is the process of how the participants interacted with their existing environments and the circumstances produced by them, highlighting the momentous events that continuously defined the individuals understanding of their own self concept as a gang member up until the point of non-membership. What was observed by a dissection of the interviewee’s accounts was that the onset of gang membership was influenced primarily by a feeling of disassociation and alienation which the participants actively sought to suppress, whereby the idea of belonging to a gang offered the remedy. The aspect of commitment was shown to be focused more towards upholding the identity of gang membership and their reputation than towards the gang itself. Reinforcing the identity maintained the individual’s social status and relevance amongst their peers, solidifying the aspired identity of gang membership. Finally, the process of desistance surfaced once the gang member identity no longer seemed beneficial. Life threats, a re-emergence of the feeling of solidarity, the experience of disloyalty and the acceptance of another identity as being more imperative were factors that separately influenced the move for the discontinuance for the projection of the gang member identity. Although the participants admit to and self proclaim ex-membership, they do nonetheless acknowledge that the gang mask could once again be put back on.
