Adverse childhood experiences & crime classifications
Get PDF1 online resource (2 unnumbered, 84 pages) : graphsIncludes abstract and appendices.Includes bibliographical references (pages 55-67).The current study was designed to explore the relationship between adverse childhood experiences (ACEs) and crime classifications to determine how the three different ACE categories differ as a function of four crime classifications, and how the number of ACEs experienced relates to chronic offending. This relationship was examined using a Canadian justice-involved population recruited through community residential facilities and support groups. ACE categories were not found to differ as a function of crime classification and the number of ACEs experienced did not relate to chronic offending. Previous research supports findings of the current study regarding the elevated rates of ACEs in justice-involved populations and notable gender differences. This exploratory study added to the ACE literature by exploring the relationship amongst all types of abuse, neglect, and household dysfunction in relation to all types of self-reported criminal convictions. Future research is encouraged to explore similar relationships among more substantial justice-involved samples
Studying eclipse-like behaviour in two AGN : NGC 6814 and Zw 229.015
Get PDF1 online resource (vii, 91 pages) : graphs, charts (some colour)Includes abstract.Includes bibliographical references (pages 84-91).Studying transient events in active galactic nuclei (AGN) can provide useful information about the AGN environment. In this work, transient-like events in NGC 6814 and Zw 229.015 were studied. Colour-colour grids, which provide better time resolution than spectral analysis and can break model degeneracies, were applied to the eclipse data for NGC 6814. These grids revealed a complex multi-cloud geometry for the obscurer, dismissing the original idea of a single, homogeneous cloud. In Zw 229.015, flux-resolved spectral analysis was used to study a concurrent dip in both the UV and X-ray light curves. The analysis attributed the likely source of the flux dip to continuum changes through either coronal variability or accretion rate changes. Timescale consideration revealed thermal processes to be the source of the variability causing the dip. Separate analyses of two different AGN showing similar transient-like behaviour, require different explanations
The effect of cyclic buckling on the structure and mechanical properties of ovine tendon
Get PDF1 online resource (xi,156, 9 unnumbered pages) : illustrations (some colour, charts (some colour), graphs (some colour)Includes abstract and appendices.Includes bibliographical references (pages 141-153).Tendons, functionally categorized as positional or energy-storing, have differing structures and mechanical properties but are both susceptible to damage. Tendinopathy is a chronic condition that exhibits repetitive mechanical overuse damage. Despite the significant societal impact of tendinopathy, its development is poorly understood, generating a plethora of suboptimal treatment methods. This thesis investigated cyclic buckling, present in tendon unloading, as the potential root cause for the initiation and subsequent damage propagation, preceding tendinopathy. Associated structural effects were investigated from the nano-to-micro scales, using fluorescence microscopy with a collagen hybridizing peptide, second harmonic generation microscopy, and polarized light microscopy. Mechanical properties were measured via tensile testing. The results showed cyclic buckling caused structural changes, from molecular denaturation to fibre kinkbanding, accompanied by reduced ultimate tensile strength. Importantly, changes were seen in both tendon types, suggesting that cyclic buckling could be a loading mode responsible for damaging human tendons that frequently suffer tendinopathy

Differential impacts of pH and acid type on Brassicaceae seed germination and seedling growth
Get PDF1 online resource (51 pages) : illustrations (some colour), graphs (some colour)Includes abstract and appendices.Includes bibliographical references (pages 41-51).Elevated acidity can be a considerable stressor for plants. Acids can arise from anthropogenic sources such as acid rain, characterized by inorganic acids like sulphuric acid. Beyond anthropogenic influences, various habitats exhibit inherent acidity due to bedrock properties, such as granite's limited buffering capacity or low pH resulting from biological activity, featuring an abundance of weak organic acids. While low pH (<4) is generally considered stressful for plants, differential impacts of distinct acid types—organic versus inorganic, strong versus weak—on plant growth and function remain unclear. To address this knowledge gap, I conducted a controlled experiment to determine whether acid responses are solely pH-dependent or if acid type specificity plays a role in plant functional responses. I grew two Brassicaceae species under factorial combinations of four pH levels (pH 1-5.5) and three acids (hydrochloric, sulfuric, and acetic) with distilled water as control, and measured seed germination, seedling growth, leaf size, shoot and root length. Seed germination, growth, and morphology increased with increasing pH across all acids. However, acid type also influenced plant responses. Hydrochloric acid promoted higher seed germination but hindered seedling growth, while acetic and sulphuric acids had the opposite effects. These results highlight the influence of acid types
on plant functions, specifically affecting distinct developmental stages. Understanding the
differential effects of acid types on various growth parameters provides insight into acid stress and potential tolerance mechanisms. My study has implications for restoration efforts in acidimpacted environments, challenging the assumption that pH alone dictates plant stress responses
Intrafamilial and Extrafamilial Criminogrenic Factors of Child Sexual Abuse
Get PDF1 online resource (27 pages)Includes abstract.Includes bibliographical references (pages 25-27).As previous research shows the rates of child sexual abuse are overly static, with all the
previous research we are still unable to help prevent such a traumatic moment in a child's life. The present study compares and contrasts criminogenic factors of intrafamilial and extrafamilial child sexual offenders. This study took eleven common factors of child sex offenders and observed how they are linked to one another as well as how they relate back to the offense. These criminogenic factors include; neglect, physical and sexual abuse, poor parental attachments, hypersexual lifestyles, sexual role and masculinity, disinhibition, atypical sexual tendencies, social incompetence, cognitive distortions, social isolation, and low self-esteem. When it comes to child sexual abuse there are two primary victimologies at play, intrafamilial and extrafamilial victims. Intrafamilial offenders are family members, this often includes those who are blood-related for example; parents, aunts and uncles, step-parents, and even siblings. Extrafamilial offenders are those who are not related to their victims, this often includes coaches, scout leaders, religious leaders, teachers, and strangers. This study is a systematic literature review aiming to identify and compare criminogenic factors of both intrafamilial and extrafamilial child sexual offenders, and to describe the typical profiles of child sex offenders based on the eleven chosen criminogenic factors. By conducting a systematic review we are able to get unbiased results and critique previous literature. This study is looking at child sexual abuse using; social learning theory, social bonds theory, and routine activity theory
Impacts of IM in AVIS
Get PDF1 online resource (125 pages) : colour illustrations, graphsIncludes abstract and appendices.Includes bibliographical references (pages 59-66).The study explored the use of self presentation behaviours (i.e., deceptive, and honest
impression management; IM) in asynchronous video interviews (AVIs). Applicants use of IM in interviews has the potential to enhance (honest IM) or detract (deceptive IM) the predictive validity of interviews. However, scant research exists on the potential impacts of IM on predictive validity of job interviews. The current study employed a novel approach by collecting data in two stages: first, participants (n = 212) completed a mock AVI; next, participants (n = 168) completed two in-basket HR tasks to capture performance. Results indicated that honest self-promotion had a positive relationship with interview and task performance, and a significant indirect effect. Other IM tactics lead to some mixed and contrary findings. Proposed moderators (experience, age, and anxiety) did not impact results. Overall, honest and deceptive IM demonstrate their importance to both interview and job performance
Star formation in clumpy, interacting galaxies
Get PDF1 online resource (xiv, 108 pages) : colour illustrations, charts (some colour), graphs (some colour)Includes abstract and appendices.Includes bibliographical references (pages 105-108).Galaxy mergers are one of the most important processes in the universe - they are a method of galaxy growth and mass assembly, and also the cause of internal dynamic changes in galaxies including star formation and quenching. In this thesis we examine two populations of interacting galaxies with data from the James Webb and Hubble space telescopes, and two equivalent populations of isolated galaxies, in order to examine the star formation trends, but also the presence of star-forming clumps of material in galactic disks. The analysis on star formation is based on a combination of the results from broadband spectral energy distribution (SED) fitting of imaging data, and Hα emission line maps from 2D slitless grism spectroscopy. We present the development and applications of a ‘clump’ detection algorithm, and examine the clumpiness of all galaxies in both samples. We find that within a narrow mass range (between 109 − 1010M⊙) that interacting galaxies are higher in both star formation rate and number of clumps, supporting common theories that mergers induce star formation, and that they are potentially tied to clump formation. Using emission line maps and the results of spectral energy distribution (SED) fitting, we investigate the clump contributions to galaxy star formation rate (SFR), comparing these results to the literature and use their behaviour to explain overall star formation and clump trends in mergers.</p
Psychedelic experiences and knowledge acquisition
No full text1 online resource (49, 1 unnumbered pages)Includes abstract.Includes bibliographical references (pages 47-49).This paper examines the potential for psychedelic experiences to facilitate knowledge acquisition by enhancing creative thought processes. Initially, the discussion is framed between entheogenic and psychotomimetic conceptions of psychedelic experiences, highlighting the historical and philosophical contention surrounding the reliability of insights gained during psychedelic experiences. But despite traditional skepticism outlined by the Argument from Alterity, which suggests that psychedelic experiences either provide redundant or unreliable knowledge, this paper challenges such conclusions and argues that psychedelic experiences can indeed help us acquire knowledge. Central to this argument is how psychedelic experiences alter our perception and cognition to boost creativity. This enhanced creativity drives the generation of new ideas, which in turn is fundamental to acquiring new knowledge. Thus, by enhancing creativity, psychedelic experiences can play a crucial role in the process of knowledge acquisition
International law and the question of recognition of Palestinian statehood: a legal subaltern reality
Get PDF1 online resource (61 pages) : colour mapsIncludes abstract.Includes bibliographical references (pages 53-61).The recognition of Palestinian statehood, specifically at the United Nations (UN), has been met with questions regarding Palestine’s fulfilment of statehood requirements set out by the Montevideo Convention on the Rights and Duties of States (1933) and Article 4 (1) of the UN Charter. This essay attempts to understand the barriers that Palestine has faced to achieving full legal recognition by drawing on the concept of International Legal subalternity (ILS) as coined by Ardi Imseis. Through an overview of the concepts of statehood and recognition and an analysis of the history of Palestine and its pursuit of statehood and recognition, a legal subaltern pattern can be discerned. This becomes especially clear through evaluating records from member states at the 6636th Security Council meeting on October 24th, 2011 regarding the Question of Palestine and the Middle East. The historic elements of this paper combined with transcripts from the Security Council meeting reveal that the case of Palestine’s recognition at the UN has been treated as a rule by law approach, rather than the rule of law
