Guilty Plea Revocation, Constitutional Waiver, and the Charter: A Guilty Plea Is Not A Trap

The entry of a guilty plea has significant constitutional ramifications. It relieves the Crown of its obligation to prove the elements of an offence beyond a reasonable doubt and constitutes a waiver by the accused of various rights including the right to put the Crown\u27s case to the test of a trial, the right to confront Crown witnesses through cross-examination and the right to remain silent in relation to the determination of legal guilt. In light of these constitutional dimensions, the article considers an issue which has received little academic attention: the revocation of a guiltyplea. The authorassesses the existing Canadian common law revocation rule, which he finds to be incompatible with the values expressed in the Canadian Charter of Rights and Freedoms owing to its narrow scope, uncertainty, and discretionary nature. He also considers the rule developed within the American federal court system as a possible alternative to the Canadian approach. The author proposes a revised revocation rule which provides for the withdrawal of a guilty plea where the accused can prove on a balance of probabilities that the guilty plea was either uninformed or involuntary, and which further allows for revocation at any time priorto sentencing unless the Crown can demonstrate that significant prejudice would result from revocation. The author counters the view that the decision to deny the revocation of a guilty plea should be subject to deference on appeal

Self-Sacrifice and the Transformation of the Hero

The literary notion of a hero is often steeped in great deeds, such as vanquishing the monster, completing Herculean tasks, or protecting the innocent from harm. The medium of the comic book also provides numerous tales of self-sacrifice that add weight to the legitimacy of a hero and their contribution to a particular society or cause. This article will consider certain themes within the self-sacrificing hero narrative in order to gain further insight into this phenomenon and will draw inspiration from Greek and Norse mythology as well as the Superhero genre within comics and film. Finally, this article will consider the cyclical nature of the hero’s journey and the importance of continual heroic rebirth in sustaining their legacy for new generations of comic book readers and film audiences. What does their sacrifice mean when the hero and even their universe is reborn at a later date

Efficacy of property marking: Police identification of stolen property

Property marking, as a situational crime prevention technique, has found to be largely ineffectual in the reduction of property theft, although past studies have not considered the role property marking as an aid to the return of stolen or lost property. However, automotive identification and some studies have found that in some cases property marking is effective. Furthermore, many crime prevention groups focus on property marking as a means to reduce crime and the fear of crime. Therefore, the study investigated the processes of lost, stolen and seized goods by law enforcement personnel. The study undertook a qualitative analysis of law enforcement property identification process, including a documentary analysis of procedures and practitioner interviews for content-thematic analysis. The study found that the use of manufacturer serial numbers was the initial line of investigative enquiry. Limiting factors were technical capability to find and use covert property markings. The successful implementation of a code of best practice or standardisation in the recording of serial numbers, and the availability of the community to quickly and easily record their property may have a significant effect in the reduction of property crimes; due to the perceived increase of risk and potential reduction of reward to the offender

An Evaluation Of The Enjoyment Levels Of Participants Of LifeLab, A Health Literacy Intervention For Socially Disadvantaged Adolescents.

Aim: LifeLab is co-designed by and for Junior Cycle students from social disadvantage in Ireland, with the hope to improve health literacy and subsequent health outcomes in this cohort. The aim of this study was to evaluate the enjoyment levels of students participating in the pilot of LifeLab, with a view to informing future development of the intervention. Method: As part of the process evaluation of the pilot of LifeLab, a series of focus groups and purposively designed enjoyment scales were completed by 80 adolescents, from one disadvantaged school in Dublin, Ireland. Inductive thematic analysis was carried out to analyse focus group data, and descriptive analysis of the enjoyment scales was conducted. Findings of the focus groups and enjoyment scales were synthesised and integrated resulting in the generation of a series of higher order and lower order themes of enjoyment. Results: Results of the inductive thematic analysis identified barriers, facilitators and suggestions for increasing enjoyment. Adolescents\u27 enjoyment of the LifeLab intervention can be improved through the integration of fun activity-based learning, competition, variety, and challenge. Conclusions: Findings suggested specific areas of improvement within the intervention, and by using the participant voice, these factors can be incorporated within the LifeLab intervention. It is hoped these refinements, as part of ongoing intervention development, may increase levels of enjoyment, which will therefore enhance the usability and success of LifeLab

Student compliance with taught indications for intravenous cannulation during clinical learning

Abstract: One of the guiding principles behind the teaching and performance of a medical intervention is to “firstly do no harm”. Gaining access to a patient’s circulatory system for the purposes of administering fluid and / or medications is commonly achieved through a procedure that involves piercing the skin with a needle and inserting a cannula into a vein. Whilst intravenous (IV) cannulation remains a relatively common procedure, routinely performed by a number of health care professionals, it has the potential to create unintended adverse effects. Subjecting patients to medical procedures in the absence of a clearly established need may be considered an unethical form of “overtreatment”. Conversely, failing to perform an intervention when it is clearly indicated is equally undesirable. For this reason, it is important that medical professionals and educators ensure a real need or indication for IV cannulation exists prior to the performance of the procedure by students. The University of Johannesburg (UJ) is one of four higher education institutions in South Africa that currently offer a four-year professional bachelor degree in emergency medical care. Intravenous cannulation is a clinical procedure that is taught in the second year of study. The didactic approach followed at the UJ is to firstly teach and assess theoretical knowledge and understanding relating to the procedure with regard to the technique, indications, risks and benefits. The procedure is then demonstrated, practiced and assessed in a simulated environment making use of an intravenous trainer (medium fidelity manikin). Thereafter students are required to demonstrate performance of the procedure a set number of times on real patients. Whilst this naturally creates a desire in students to perform IV cannulation when the opportunity presents itself, as mentioned above, seeking clear indications for the performance of the procedure is essential to prevent unnecessary exposure of patients to potential adverse effects. The Department of Emergency Medical Care at the UJ currently teaches four indications for intravenous cannulation in the pre-hospital setting which are well supported by literature. These include: a) the administration of intravenous fluid in an effort to reverse hypovolaemic and associated dehydrated states, b) administration of intravenous medications, c) securing intravenous access in the case of acutely-ill, high-acuity “priority 1” or “code red” patients and d) obtaining blood samples/specimens for further laboratory testing. The authors aimed to assess the extent to which emergency medical care students may have been establishing IV access on patients during the course of their clinical learning without a clear indication

A Survey of the Mental Health of UK Olympic and Paralympic Sport Athletes.

Abstract This study examined the prevalence of psychological distress and well-being amongst elite athletes in the UK. An online survey was emailed to 753 athletes within the English Institute of Sport. Response rate 52.3%. 371 participants (median age 25) completed measures of psychological distress and subjective well-being alongside demographics and sport-related variables. High or very high psychological distress was reported by 23.7%. Poor subjective well-being was reported by 18.8%. Of those reporting psychological distress, 9% also reported good subjective well-being. The odds of psychological distress and poor well-being increased if the athlete was female (OR 2.03, distress; OR 2.00, poor well-being), currently injured or ill (OR 1.87; OR 1.93) or planning to retire (OR 4.74; OR 8.10). Likelihood of poor well-being increased if a non-podium athlete (OR 0.98). Paralympic sport athletes reported greater psychological distress than Olympic sport athletes (p = .040). Winter sport athletes reported higher psychological distress than summer sport athletes (p = .044). Overall mean score (17.9, SD 6.5) was indicative of a moderate level of psychological distress. Mental health support plans should include regular athlete screening of both psychological distress and subjective well-being

Effects of mental imagery use on anxiety, confidence, mental well-being, and performance in track and field athletes

Background: Student athletes can experience a number of stressors above and beyond those of their classmates, one being competition anxiety in their specific sport, which is common among varsity athletes (Storch, Storch, Killiany, & Roberti, 2005). Unfortunately, the tools to help with the demands of their sport mentally are often overlooked by not only the athletes, but their coaches, teammates, and supporters. The purpose of the present study was to introduce imagery as a tool to help deal with competition anxiety (i.e., fear of failure), and to improve confidence, mental well-being, and performance. Methods: Two female varsity level throwers (Mage = 20) met individually with the researcher twice a week during the competitive season. Athletes were first introduced to breathing and relaxation techniques, followed by basic imagery scripts. For each session, the imagery scripts were changed and adjusted based on the needs and feedback from the athletes to focus on different elements (e.g., anxiety, technique, recovering from a bad throw). Results: Both athletes decreased their anxiety levels, while increasing their self-confidence, mental well-being, and performance. Discussion & Conclusion: The results highlight the positive effect of employing imagery in sport life. Interdisciplinary Reflection: Imagery use can be also applied in other aspects of athletes’ lives
