The Blame Game: Perceptions of Blame, Responsibility and Seriousness in Cyberbullying

Cyberbullying is gaining increasing media attention. Victims may be reluctant to report such bullying due to the perception by others that these victims somehow play a role in their own victimization. This perception, often referred to as victim blame, has been commonly researched in child sexual abuse, rape and hate crime cases, but it has not really been examined in cases of cyberbullying. To assess victim blame, 241 participants were recruited and asked to read a scenario of cyberbullying that involved either a 14-year-old or a 20-year old victim. Perpetrator gender and victim gender were also manipulated. It was found that perceptions regarding the scenario were influenced by the gender of the perpetrator and the age of the victim. This was particularly the case when perceptions of the seriousness of the crime and the necessity for legal action were assessed.

Public Attitudes and Perceptions toward the NCRMD Defense

In Canada today, a person who performs an illegal act that is deemed to be the result of a mental illness is eligible for the not criminally responsible on account of mental disorder (NCRMD) defense. This defense can remove the blame and responsibility from an individual for an act that would otherwise be considered criminal. The present study examines possible factors that may influence people’s opinions on the defense and the treatment of mentally ill offenders in general. A sample of 257 participants (190 women, 38 men, 29 gender unknown) with ages ranging from 18-73 (M = 26.59, SD = 12.59) completed an online survey that assessed attitudes, opinions, and knowledge of mental illness, mentally ill offenders, and the NCRMD defense. Results showed that several factors were related to how positive or negative participants considered the defense to be, including experience with mental illness or the justice system and knowledge of schizophrenia or the sentences associated with the NCRMD defense. Findings suggest education is important in attaining more positive views of mentally ill offenders and the NCRMD defense.

INVERTEBRATE CONTRIBUTION TO LEAF BREAKDOWN IN PYNN’S BROOK, NL.

Leaf bags of fine and coarse mesh were placed at two locations, one with an open tree canopy, the other with a closed tree canopy, in Pynn’s Brook on June 30th 2015. Bags were collected after 2, 30, 37 and 44 days. After collection, invertebrates were counted and leaf material remaining was determined to measure leaf breakdown rate. There was no significant difference in leaf mass remaining (R) between the two sites. Comparisons between mesh types found a difference in leaf breakdown at two collection days. The difference at 2 days was small (2.7%) and may not be biologically meaningful. At 37 days, the difference was larger (8.41%) and may be related to a larger proportion of shredder taxa, seen in coarse mesh bags, or higher absolute numbers of invertebrates. The invertebrate community was dominated by Diptera spp. across all collection days and mesh types, but after 37 days, communities in coarse mesh bags had a higher proportion of shredder orders than did fine mesh bags.

Structured decision making as a tool for facilitating stakeholder engagement in non-renewable resource management: using the case study of hydraulic fracturing in the Green Point Shale formation in western Newfoundland

This thesis examines the importance of effective stakeholder engagement that complies with the doctrines of social justice in non-renewable resources management decision-making. It uses hydraulic fracturing in the Green Point Shale Formation in Western Newfoundland as a case study. The thesis uses as theoretical background John Rawls’ and David Miller’ theory of social justice, and identifies the social justice principles, which are relevant to stakeholder engagement. The thesis compares the method of stakeholder engagement employed by the Newfoundland and Labrador Hydraulic Fracturing Review Panel (NLHFRP), with the stakeholder engagement techniques recommended by the Structured Decision Making (SDM) model, as applied to a simulated case study involving hydraulic fracturing in the Green Point Shale Formation. Using the already identified social justice principles, the thesis then developed a framework to measure the level of compliance of both stakeholder engagement techniques with social justice principles. The main finding of the thesis is that the engagement techniques prescribed by the SDM model comply more closely with the doctrines of social justice than the engagement techniques applied by the NLHFRP. The thesis concludes by recommending that the SDM model be more widely used in non- renewable resource management decision making in order to ensure that all stakeholders’ concerns are effectively heard, understood and transparently incorporated in the nonrenewable resource policies to make them consistent with local priorities and goals, and with the social justice norms and institutions.

Analysis of N-nitrosames in water using micellar electrokinetic chromatography (MEKC) and development of online and offline methods of extraction and enrichment of neutral polar analytes

Evaluation of the quality of the environment is essential for human wellness as pollutants in trace amounts can cause serious health problem. Nitrosamines are a group of compounds that are considered potential carcinogens and can be found in drinking water (as disinfection byproducts), foods, beverages and cosmetics. To monitor the level of these compounds to minimize daily intakes, fast and reliable analytical techniques are required. As these compounds are relatively highly polar, extraction and enrichment from environmental samples (aqueous) are challenging. Also, the trend of analytical techniques toward the reduction of sample size and minimization of organic solvent use demands new methods of analysis. In light of fulfilling these requirements, a new method of online preconcentration tailored to an electrokinetic chromatography is introduced. In this method, electroosmotic flow (EOF) was suppressed to increase the interaction time between analyte and micellar phase, therefore the only force to mobilize the neutral analytes is the interaction of analyte with moving micelles. In absence of EOF, polarity of applied potential was switched (negative or positive) to force (anionic or cationic) micelles to move toward the detector. To avoid the excessive band broadening due to longer analysis time caused by slow moving micelles, auxiliary pressure was introduced to boost the micelle movement toward the detector using an in house designed and built apparatus. Applying the external auxiliary pressure significantly reduced the analysis times without compromising separation efficiency. Parameters, such as type of surfactants, composition of background electrolyte (BGE), type of capillary, matrix effect, organic modifiers, etc., were evaluated in optimization of the method. The enrichment factors for targeted analytes were impressive, particularly; cationic surfactants were shown to be suitable for analysis of nitrosamines due to their ability to act as hydrogen bond donors. Ammonium perfluorooctanoate (APFO) also showed remarkable results in term of peak shapes and number of theoretical plates. It was shown that the separation results were best when a high conductivity sample was paired with a BGE of lower conductivity. Using higher surfactant concentrations (up to 200 mM SDS) than usual (50 mM SDS) for micellar electrokinetic chromatography (MEKC) improved the sweeping. A new method for micro-extraction and enrichment of highly polar neutral analytes (N-Nitrosamines in particular) based on three-phase drop micro-extraction was introduced and its performance studied. In this method, a new device using some easy-to-find components was fabricated and its operation and application demonstrated. Compared to conventional extraction methods (liquid-liquid extraction), consumption of organic solvents and operation times were significantly lower.

Transdermal delivery of cyclosporin A by electrically enhanced permeation techniques

Transdermal drug delivery has recently received increasing attention in the face of growing challenges to deliver peptide and protein drugs. Controlled transdermal delivery is an important route for the delivery of peptides and proteins that can maintain the therapeutic effectiveness of the drug by minimizing enzymatic degradation which is a major concern in other noninvasive routes of delivery such as the oral route. Although the advantages of transdermal delivery are very desirable, the natural obstacle to drug entry imposed by the skin's barrier function makes it one of the most difficult route of administration. Iontophoresis and electroporation have been reported to be useful as permeation enhancing techniques in the transdermal delivery of protein and peptide drugs. The objective of present study is to use the above enhancement techniques to deliver cyclosporin A (CSA) to treat psoriasis. The in vitro experiments were performed using hairless rat skin as the model with Franz diffusion cells for iontophoresis and custom made diffusion cells for electroporation. The donor drug solution of CSA consisted of an aqueous solution of CSA - polymer solid dispersion, coevaporate, and/or a hydroethanolic solution of CSA PBS was used as the receiver solution. ³H labelled CSA and ¹⁴C labelled ethanol were used to facilitate analysis using a liquid scintillation counter. The control experiment consisted of passive diffusion study. Silver/silver chloride electrodes were used in all studies. In the iontophoresis experiments a constant DC current (0.5 mA/cm²) was used. In the electroporation experiments different delivery parameters were studied: (1) applied electrode voltage (Uelectrode), (2) decay time constant (τ), (3) the number of pulses delivered - single or multiple, and { 4) the time of diffusive contact with drug after electroporation ('contact duration'). Compared to the passive diffusion, iontophoresis did not result in a significant increase in the amount of CSA delivered transdermally with both the CSA-polymer donor and hydroethanolic drug solutions. With the use of electroporation there was a significant increase in the transdermal delivery, compared to passive transport. With the CSA-polymer coevaporate donor solution the increase in delivery was only about 6 fold higher whereas with the hydroethanolic solution the increase was about 60 times higher compared to passive diffusion. The 'contact duration• was an important fader and a 4-hour 'contact duration' was found to be the optimum time period required for effective transdermal delivery. Use of single pulse (τ=5.6 ms) electroporation resulted in a significant increase {p<0.05) in the delivery of CSA in skin {CSA.n) and EtOH in receiver (EtOHreceiver). With multiple pulse (τ=10 ms. 25 pulses) the increase in CSAskin was more pronounced with a 60 fold increase than compared to the passive delivery. However there was no significant increase in the other two quantities viz. CSAreceiver, and EtCHreceiver.

Electronic Technology in NL Schools: An Environmental Scan, 2015-16

This study was designed to obtain information on the prevalence of electronic technology—in terms of availability and use—in classrooms in Newfoundland and Labrador. An online survey was developed and delivered electronically to a randomly chosen sample of 800 k-12 educators in Newfoundland & Labrador’s English School District during Winter, 2016. In total, 377 surveys were completed. Among other things, the findings showed that SMART Boards and iPads were receiving significant usage while the usage of computer labs and of various social media tools was not particularly high.
