Recreational angling tournaments: participants' expenditures

Fishing tournaments are a common feature in recreational angling across a wide range of target species in both fresh and salt waters. Tournaments are organised for a number of purposes, including as commercial enterprises; as fund-raising initiatives for angling clubs; for economic development purposes (e.g. tourism); as well as improve participants' skill levels. Most tournaments are confined to geographically small areas and usually occur over a small number of days, which can mean a pulse of economically significant activity in the local area. This paper analyses the nature of expenditure associated with angling tournaments, including travel, food and accommodation, and angling-related expenditures as a function of socio-economic and angler characteristics. Analysis based on 106 tournaments across Ireland during 2013 finds a clear 80/20 segmentation between ‘high’- and ‘low’-spend anglers and that the segmentation occurs across all fish target species considered. The analysis also finds that British coarse anglers participating at Irish angling tournaments spend considerably more than other anglers irrespective of target species or angler country of origin.     

The kinematic differences between accurate and inaccurate squash forehand drives for athletes of different skill levels

ABSTRACT

To maintain the accuracy of squash shots under varying conditions, such as the oncoming ball’s velocity and trajectory, players must adjust their technique. Although differences in technique between skilled and less-skilled players have been studied, it is not yet understood how players vary their technique in a functional manner to maintain accuracy under varying conditions. This study compared 3-dimensional joint and racket kinematics and their variability between accurate and inaccurate squash forehand drives of 9 highly skilled and 9 less-skilled male athletes. During inaccurate shots, less-skilled players hit the ball with a more open racket, demonstrating a difference in this task-relevant parameter. No joint kinematic differences were found for accuracy for either group. Coordinated joint rotations at the elbow and wrist both displayed a “zeroing-in” effect, whereby movement variability was reduced from the initiation of propulsive joint rotation to a higher consistency at ball-impact; potentially highlighting the “functionality” of the variability prior to the impact that enabled consistent task-relevant parameters (racket orientation and velocity) under varying conditions. Further, highly skilled players demonstrated greater consistency of task-relevant parameters at impact than less-skilled players. These findings highlight the superior ability of highly skilled players to adjust their technique to achieve consistent task-relevant parameters and a successful shot.     

A theory of instruction for introductory programming skills

ABSTRACT

Background and Context: Current introductory instruction fails to identify, structure, and sequence the many skills involved in programming.

Objective: We proposed a theory which identifies four distinct skills that novices learn incrementally. These skills are tracing, writing syntax, comprehending templates (reusable abstractions of programming knowledge), and writing code with templates. We theorized that explicit instruction of these skills decreases cognitive demand.

Method: We conducted an exploratory mixed-methods study and compared students’ exercise completion rates, error rates, ability to explain code, and engagement when learning to program. We compared material that reflects this theory to more traditional material that does not distinguish between skills.

Findings: Teaching skills incrementally resulted in improved completion rate on practice exercises, and decreased error rate and improved understanding of the post-test.

Implications: By structuring programming skills such that they can be taught explicitly and incrementally, we can inform instructional design and improve future research on understanding how novice programmers develop understanding.     

A Person-Centered Approach to Students' Evaluations of Perceived Fear Appeals and Their Association With Engagement

A person-centered approach was employed to investigate how students' evaluation of perceived teacher utility value messages, i.e., fear appeals, as a threat and as a challenge, combined within individuals and how these combinations related to student engagement. Two studies were conducted with students in their final two years of secondary education. Empirically distinct clusters emerged at two time points in the academic year. Evaluating the message in the fear appeal at a higher level of challenge than threat was beneficial. Unexpectedly, high threat was associated with high engagement, as long as high challenge was also present, however, this combination was also related to high emotional disaffection. Moderate threat combined with moderate challenge had the most detrimental relationship with student engagement. Educational interventions should aim to increase the likelihood of a challenge evaluation.     

Root causes of errant ordered radiology exams: Results of a needs assessment

A comprehensive needs assessment was conducted at ATA hospital to determine the root causes of a high number of errant radiology orders from requesting physicians. The Human Performance Technology Model, Gilbert's Behavior Engineering Model, and Rummler and Brache's Nine Performance Variables Model guided the needs assessment process. Three solutions were proposed. The development of the long‐term solution, a software utility, has been initiated. The Behavior Engineering Model was used to identify possible solutions to post‐training performance gaps identified during the evaluation.     

Influence of improved teaching practices on student satisfaction ratings for two undergraduate units at an Australian university

To track the quality of instruction delivered at the University of Western Australia, the university surveys all units using its Students’ Unit Reflective Feedback (SURF) metrics, and faculties use these metrics to benchmark student satisfaction. Consequently, teaching staff are actively encouraged to adopt teaching practices that will increase the average levels of these metrics. Using a ‘before-after’ approach, we compared these metrics before and after the implementation of improved teaching practices that addressed specific weaknesses identified through student responses for two undergraduate units. Despite the implementation of improved teaching practices, SURF scores did not increase significantly for the two units assessed, due possibly to the components of the academic programme covered by the SURF questions, the field-based nature of the units, and the difficulty in measuring an increase in the SURF scores of units which already score highly. This poor sensitivity of the SURF metrics to the implementation of improved teaching practices could have implications for their use for performance assessment by the university.     

Three-dimensional assessment of squats and drop jumps using the Microsoft Xbox One Kinect: Reliability and validity

The Microsoft Xbox One Kinect? (Kinect V2) contains a depth camera that can be used to manually identify anatomical landmark positions in three-dimensions independent of the standard skeletal tracking, and therefore has potential for low-cost, time-efficient three-dimensional movement analysis (3DMA). This study examined inter-session reliability and concurrent validity of the Kinect V2 for the assessment of coronal and sagittal plane kinematics for the trunk, hip and knee during single leg squats (SLS) and drop vertical jumps (DVJ). Thirty young, healthy participants (age = 23 ± 5yrs, male/female = 15/15) performed a SLS and DVJ protocol that was recorded concurrently by the Kinect V2 and 3DMA during two sessions, one week apart. The Kinect V2 demonstrated good to excellent reliability for all SLS and DVJ variables (ICC ≥ 0.73). Concurrent validity ranged from poor to excellent (ICC = 0.02 to 0.98) during the SLS task, although trunk, hip and knee flexion and two-dimensional measures of knee abduction and frontal plane projection angle all demonstrated good to excellent validity (ICC ≥ 0.80). Concurrent validity for the DVJ task was typically worse, with only two variables exceeding ICC = 0.75 (trunk and hip flexion). These findings indicate that the Kinect V2 may have potential for large-scale screening for ACL injury risk, however future prospective research is required.     

I CARE: Development and Evaluation of a Campus Gatekeeper Training Program for Mental Health Promotion and Suicide Prevention

Addressing the need for suicide prevention on campus, I CARE training, developed and facilitated by counseling center clinicians, trains students, staff, and faculty to provide support to students experiencing distress or mental health problems. We assessed its impact using a mixed-methods approach. Quantitative analyses demonstrated significant increases in knowledge of intervention skills and readiness to intervene from pretraining to posttraining. Knowledge and readiness remained significantly higher than preworkshop for the entire follow-up evaluation period, extending 15 months posttraining. Qualitative analyses revealed the value of experiential activities and emotional processing in increasing participants’ comfort and preparedness to intervene in challenging situations.
