Without the explanatory power of general theoretical principles, criminal justice educators are limited to subjectively describing the structure and function of our systems of criminal justice rather than explaining why these systems behave the way they do. Because of this, criminal justice lacks integrity as a legitimate academic discipline that seeks to meet the objectives of a liberal arts education. This paper explores the establishment of ideology as a first principle of criminal justice, derived from political philosophy and sociological theory. We examine ways to build upon this principle as a means of teaching criminal justice within the guise of the liberal arts tradition by guiding students toward a deeper understanding of the nature of our criminal justice systems and their place in larger society. 相似文献

Abstract The belief that literature can teach us something about life is intuitively plausible but there is a view of literary education that would preclude a teacher from making a direct link between imaginative literature and life. A comprehensive epistemological position that supports this view is to be found in the work of Michael Oakeshott. In challenging this theory of literary education and the philosophy of knowledge that informs it, the article discloses in Oakeshott's work evidence of a more nuanced and defensible view of the role of literature in education. 相似文献

Abstract Based on literature identifying movement imagery, observation, and execution to elicit similar areas of neural activity, research has demonstrated that movement imagery and observation successfully prime movement execution. To investigate whether movement and observation could prime ease of imaging from an external visual-imagery perspective, an internal visual-imagery perspective, and kinesthetic modality, 36 participants (M age = 20.58; SD = 3.11; 18 women and 18 men) completed an adapted version of the Movement Imagery Questionnaire-Revised under four modes of delivery (movement prime, external observation prime, internal observation prime, and image-only). The results revealed that ease of imaging was significantly greater during the movement and observation prime conditions compared to the image-only condition (p < .05). Specifically when priming external visual imagery and internal visual imagery, observation facilitated ease of imaging only when the perspective was congruent with the imagery perspective. The results support the use of movement and observation to facilitate ease of imaging, but highlight the importance of considering the visual perspective when using observation. 相似文献

We examined whether altering the amount of and moment when visual information is presented affected observational learning for participants practicing a bowling skill. On Day 1, four groups practiced a cricket bowling action. Three groups viewed a full-body point-light model, the model's bowling arm, or between-limb coordination of the model's left and right wrists only. Following retention tests on Day 2, all participants practiced after viewing a full-body display. Retention was again tested on Day 3. Bowling accuracy improved in all four practice groups. Kinematics of the bowling arm became more like the model for the full-body and intralimb groups only. All groups improved on measures of interlimb coordination. Visual search data indicated that participants mainly focused their gaze on the model's bowling arm. These data lead to the suggestion that viewing “end-effector” information (i.e., information pertaining to the bowling arm) is an important perceptual constraint early in observational learning. Implicit manipulations designed to increase attention to other sources of information did not facilitate the learning process. 相似文献

The aims of this study were to examine and compare selected physiological and metabolic responses of wheelchair athletes in two paraplegic racing classes [T3: n?=?8 (lesion levels T1–T7; paraplegics); T4: n?=?9 (lesion levels below T7; paraplegics)] to prolonged exercise. In addition, we describe the responses of three tetraplegic athletes [T2: n?=?3 (lesion levels C6/C7: tetraplegics)]. Twenty athletes completed 90?min of exercise at 75% [Vdot]O2peak on a motorized treadmill adapted for wheelchairs. The mean (±s) heart rates of the T3 and T4 racing classes were 165±2 and 172±6 beats?·?min?1, respectively. For the T4 racing class, heart rate gradually increased during the test (P?<0.05), whereas for the T3 racing class, heart rate reached a plateau after an initial increase. The mean heart rate of the tetraplegics was 114±3 beats?·?min?1. The T3 and T4 classes exhibited similar respiratory exchange ratios, plasma lactate and glucose concentrations throughout the test. For both the T3 and T4 racing class, free fatty acid, glycerol, ammonia, urea and potassium concentrations had increased from resting values by the end of the test (P?<0.05). In conclusion, the results of this study suggest that endurance-trained wheelchair athletes are able to maintain velocities equivalent to the same relative exercise intensity (75% [Vdot]O2peak) for prolonged periods irrespective of lesion level. 相似文献

Abstract Power output and heart rate were monitored for 11 months in one female ([Vdot]O2max: 71.5 mL · kg?1 · min?1) and ten male ([Vdot]O2max: 66.5 ± 7.1 mL · kg?1 · min?1) cyclists using SRM power-meters to quantify power output and heart rate distributions in an attempt to assess exercise intensity and to relate training variables to performance. In total, 1802 data sets were divided into workout categories according to training goals, and power output and heart rate intensity zones were calculated. The ratio of mean power output to respiratory compensation point power output was calculated as an intensity factor for each training session and for each interval during the training sessions. Variability of power output was calculated as a coefficient of variation. There was no difference in the distribution of power output and heart rate for the total season (P = 0.15). Significant differences were observed during high-intensity workouts (P < 0.001). Performance improvements across the season were related to low-cadence strength workouts (P < 0.05). The intensity factor for intervals was related to performance (P < 0.01). The variability in power output was inversely associated with performance (P < 0.01). Better performance by cyclists was characterized by lower variability in power output and higher exercise intensities during intervals. 相似文献

Two groups of male subjects received a total of 7½-min practice on the pursuit rotor, with a day's rest following the first 5 min. The transcendental meditation (TM) group consisted of 15 volunteers who meditated twice daily and who had been practicing the technique for an average of 28 months. The other group consisted of 15 nonmeditators. The results did not support the expectations that the meditators would demonstrate superior learning and performance and less reactive inhibition than the nonmeditators. Indeed, it was found that in terms of performance, and of learning to a lesser degree, the meditators were significantly poorer. While there was some limited support for the expectation that meditators would exhibit less intra-individual variability, the trends for inter-individual differences indicated that the individual meditators became much less alike than did the nonmeditators when practice was resumed on the second day. It was concluded that certain benefits attributed to the practice of TM (such as greater within-subject consistency, less anxiety, increased alertness and awareness) are not apparent when a novel perceptual-motor skill is being learned. Instead, it appears that the effects of TM are detrimental to such performance. 相似文献

Abstract A 6-min rowing ergometer test was administered to 116 candidates for Junior, Colt, and Olympic New Zealand crews. Stroke frequency, work output, and heart rates were used to assess rowing fitness and to compare min-by-min performance of the selected and unselected trialists. Throughout the duration of the test, the Junior and Olympic selected oarsmen demonstrated a greater ability to tolerate this type of heavy work than did the unselected oarsmen. The Colt trialists were relatively homogeneous and their subgroup differences did not reach significance. In comparison to earlier work using a similar sample, the present data indicate a general increase in rowing ability. 相似文献
