Predicting Physical, Verbal, Social, Racial, and Sexual Bullying with Individual and Environmental Factors from an Evolutionary Ecological Framework

Evidence exists for subtypes of bullying, but there is a lack of studies simultaneously investigating the factors that influence each subtype. The purpose of my thesis was to investigate how individual and environmental factors independently and interactively predict physical, verbal, social, racial, and sexual bullying using an evolutionary ecological framework. Adolescents (N = 225, M = 14.05, SD = 1.54) completed self-reports on demographics, HEXACO personality, Rothbart’s temperament, parenting, friendship quality, school connectedness, and socio-economic status. Subtypes were predicted by low Honesty-Humility in addition to other personality and demographic factors with the exception of physical bullying, which was predicted by environmental factors. Results suggest adolescents adaptively and selectively use bullying to exploit victims and obtain resources, although the subtype used may depend on individual factors bullies possess within Bronfenbrenner’s microsystem, instead of the meso- and exo- systems. Anti-bullying efforts should target these factors and reinforce alternative strategies to obtain resources.

Preliminary characterization of VmTPT2, a putative monoterpene indole alkaloid (MIA) transporter from Vinca minor L. (Apocynaceae)

The various steps of monoterpene indole alkaloid (MIA) biosynthesis are known to occur in specialized cell types and subcellular compartments. Numerous MIAs display powerful biological activities that have led to their use as pharmaceutical treatments for cancer, hypertension and malaria. Many of these compounds accumulate on the leaf surface of medicinally important Apocynaceae plants, which led to the recent discovery and characterization of an ABC transporter (CrTPT2) that was shown to mobilize catharanthine from its site of biosynthesis in epidermal cells to the leaf surface of Catharanthus roseus. Bioinformatic analysis of transcriptomes from several geographically distant MIA-producing species led to the identification of proteins with high amino acid sequence identity to CrTPT2. Molecular cloning of a similar transporter (VmTPT2) from Vinca minor was carried out and expressed in a yeast heterologous system for transport experiments and functional characterization. In planta studies involved transcript expression analysis of the early MIA biosynthetic gene VmTDC and putative transporter VmTPT2, and alkaloid profile analyses. RT-qPCR results showed that VmTPT2 expression increased 15-fold between the first two leaf pairs, and high levels were maintained across older leaves. The alkaloid accumulation profile on leaf surfaces matched that of VmTPT2 expression, especially for the MIAs vincadifformine and vincamine. Gene expression and alkaloid profile analyses suggest that the functional protein may act as a similar transporter to CrTPT2. However, although VmTPT2 had 88.4% identity at the amino acid level to CrTPT2, it displayed an altered expression pattern in planta across developing leaves, and functional characterization using a previously developed yeast heterologous system was unsuccessful due to difficulties with reproducibility of transport assays.

The Relative Age Effect in Minor Ice Hockey: Investigating the 'Underdog Effect'

Abstract The Relative Age Effect (RAE), defined as a skewed birth date distribution, has been identified as a known phenomenon in minor ice hockey. The purpose of this study was to investigate the relationship between the RAE, physical measurements, and skating ability/in-game performance in forty-four youth male ice hockey players competing in the same age cohort. Physical anthropometrics, grip strength, in-game performance and skating abilities were measured. An RAE was found in the sample (χ2(3, N = 44) = 12.18, p = 0.007). Players born in the first half of the age cohort had longer leg length (F(1,42) =4.49 , p = 0.04), larger body mass (F(1,42) = 3.90, p = 0.05), and stronger grip strength (F(1,42) = 7.58, p = 0.009). Performance scores were negatively associated with grip strength (r = -.443, p = 0.003). Findings suggest that adequate skill development can help relatively younger players overcome physical maturity disadvantages.

Personality traits and individual differences predict changes in postural control under conditions of height-induced postural threat

This thesis explored whether individual characteristics could predict changes in postural control in young adults under conditions of height-induced postural threat. Eighty-two young adults completed questionnaires to assess trait anxiety, trait movement reinvestment, physical risk-taking, and previous experience with height-related activities. Tests of static (quiet standing) and anticipatory (rise to toes) postural control were completed under conditions of low and high postural threat manipulated through changes in surface height. Individual characteristics were able to significantly predict changes in static, but not anticipatory postural control. Trait movement reinvestment and physical risk-taking were the most influential predictors. Evidence was provided that changes in fear and physiological arousal mediated the relationship between physical risk-taking and changes in static postural control. These results suggest that individual characteristics shape the postural strategy employed under threatening conditions and may be important for clinicians to consider during balance assessment and treatment protocols.

Sport Values of Bantam, Midget and Intermediate Female Hockey Players and Their Minor Hockey Associations

The sport values of female hockey players and their minor hockey associations were explored to better inform a values-based approach for adult-managed minor hockey. Data were collected from 294 participatory HL and competitive Rep players (12-22 years of age) using the Youth Sport Values Questionnaire-2 and from 30 hockey association board members using a modified YSVQ-2. Results indicated player importance (VI) ratings for Moral (M = 4.08) and Competence (M = 4.15) values were not significantly different but were significantly higher than Status (M = 2.11) value. Significant weak relationships between age and competition level versus VI ratings were found. There were medium/ high Moral, medium/ low Competence and high/ high Status value congruence between Rep and HL Player-Board Members, respectively. Based upon the findings, girls’ minor hockey associations need to recognize the values female youth players prioritize, and ensure each is considered within a values-based decision-making approach to governance.

Profiling young carers' lives: An examination of individual, family, and social contexts

Young carers (YCs) who provide prolonged care for ill, disabled, or addicted family member(s) face a tremendous risk for negative developmental trajectories when remaining hidden (Charles, Stainton, & Marshall, 2009; Charles, 2011; Cass, 2007). Despite a growing recognition of YCs, understanding how providing care impacts a young person is not fully understood. The present study aimed to investigate circumstantial, family, and individual factors which may be associated with YCs’ caregiving role. By comparing YCs to a normative sample, a comprehensive YC profile was formed. A secondary comparative analysis was conducted on 124 YCs (72 females and 52 males, Mage = 12) and a normative sample (n = 124) matched on YCs’ age, gender, and number of siblings within the family. Unique attributes of the YC population were discussed, thereby creating a YC profile. Future research may be able to use this profile to promote identification and recognition of YCs.

Brand Associations of Minor Hockey Tournaments: Understanding the Rep Hockey Parents' Perspective

Tournaments and other hockey-related activities have been calculated to be a significant driver of tourist dollars for many regions across Canada. The competition to attract teams to participate in tournaments, which benefit the tournament organizers and the communities in which they reside, is significant. Consequently, the purpose of the study was to assess the brand associations that representative (rep) minor hockey parents from Ontario’s Greater Golden Horseshoe Region perceive as relevant when considering ideal tournaments for their child to participate in. Brand associations have been classified as the attributes, benefits, or attitudes one uses to develop a perception of a product or service. To investigate the current study, 30 interviews were conducted using a laddering interview technique. Findings indicate that there are seven attributes and nine benefits that impact a tournament’s brand association including: competition, tournament operations, accommodations, bonding, fun, parity, and time management. The interrelationship between the identified attributes and benefits is discussed while recommendations and directions for future research are presented.

Optimizing Computational Frameworks to Study the Influence of the Protein Environment on the Individual Site Energies of Chromophores in Photosystem II of Photosynthesis

Photosynthesis is a process in which electromagnetic radiation is converted into chemical energy. Photosystems capture photons with chromophores and transfer their energy to reaction centers using chromophores as a medium. In the reaction center, the excitation energy is used to perform chemical reactions. Knowledge of chromophore site energies is crucial to the understanding of excitation energy transfer pathways in photosystems and the ability to compute the site energies in a fast and accurate manner is mandatory for investigating how protein dynamics ef-fect the site energies and ultimately energy pathways with time. In this work we developed two software frameworks designed to optimize the calculations of chro-mophore site energies within a protein environment. The first is for performing quantum mechanical energy optimizations on molecules and the second is for com-puting site energies of chromophores in a fast and accurate manner using the polar-izability embedding method. The two frameworks allow for the fast and accurate calculation of chromophore site energies within proteins, ultimately allowing for the effect of protein dynamics on energy pathways to be studied. We use these frame-works to compute the site energies of the eight chromophores in the reaction center of photosystem II (PSII) using a 1.9 Å resolution x-ray structure of photosystem II. We compare our results to conflicting experimental data obtained from both isolat-ed intact PSII core preparations and the minimal reaction center preparation of PSII, and find our work more supportive of the former.
