Need Support and Need Thwarting: A Meta-Analysis of Autonomy, Competence, and Relatedness Supportive and Thwarting Behaviors in Student Populations.

In this meta-analysis, we review the nomological networks of six need-supportive and need-thwarting categories, as defined by self-determination theory (SDT), and as they apply to students in educational contexts. We conducted a synthesis of 8693 correlations from 637 samples ( = 388,912). A total of 72 covariates were examined, resulting in 183 meta-analytic effects reported.

Do Patients With Neck of Femur Fractures (NOFF) Experience Long Pre-Hospital Delays in the United Kingdom?

Background and objective It is well documented that prolonged preoperative delay is associated with increased morbidity and mortality among patients presenting with neck of femur fractures (NOFF). The target time from arrival to the emergency department (ED) to be transported to the theatre for these patients in England is 36 hours. However, the time before the patient arrives at the hospital is not often considered.

Pathways to Student Motivation: A Meta-Analysis of Antecedents of Autonomous and Controlled Motivations.

Students' self-determined motivation (acting out of interest, curiosity, and abiding values) is associated with higher academic well-being, persistence, and achievement. Self-determination theory posits that self-determined motivation is dependent on the satisfaction of three psychological needs (relatedness, competence, and autonomy), which are in turn facilitated through need-supportive behaviors from notable others. In this meta-analysis, conducted over 144 studies and more than 79,000 students, we sought to overview pathways to student motivation in order to verify (1) how do psychological needs rank in the strength of their prediction of self-determined motivation and (2) which autonomy-support providers (parents or teachers) are the most relevant for psychological need satisfaction in students and self-determined motivation.

Student Motivation and Associated Outcomes: A Meta-Analysis From Self-Determination Theory.

Student outcomes are influenced by different types of motivation that stem from external incentives, ego involvement, personal value, and intrinsic interest. The types of motivation described in self-determination theory each co-occur to different degrees and should lead to different consequences. The associations with outcomes are due in part to unique characteristics and in part to the degree of autonomy each entails.

The tripartite model of intrinsic motivation in education: A 30-year retrospective and meta-analysis.

Introduction: Intrinsic motivation is a well-established concept in psychology, yet, different types of intrinsic motivation have not been thoroughly investigated. We examined covariates associated with three types of intrinsic motivation from self-determination theory (SDT) within the education context: IM to know, IM to accomplish, and IM to experience stimulation.

Methods: A meta-analysis was conducted on samples examining the tripartite model of intrinsic motivation between 1989 and 2019.

Rapid accelerations of Antarctic Peninsula outlet glaciers driven by surface melt.

Atmospheric warming is increasing surface melting across the Antarctic Peninsula, with unknown impacts upon glacier dynamics at the ice-bed interface. Using high-resolution satellite-derived ice velocity data, optical satellite imagery and regional climate modelling, we show that drainage of surface meltwater to the bed of outlet glaciers on the Antarctic Peninsula occurs and triggers rapid ice flow accelerations (up to 100% greater than the annual mean). This provides a mechanism for this sector of the Antarctic Ice Sheet to respond rapidly to atmospheric warming.

A unique presentation of destructive shoulder arthropathy in the chronic phase of chronic myeloid leukaemia.

We present a previously unreported case of rapidly progressing, destructive shoulder arthropathy as an initial presentation of chronic phase chronic myeloid leukaemia. This patient initially presented to clinic for consideration of an arthroplasty for symptom relief; however, her loss to follow-up yielded a rapid progression of her symptoms. Bone marrow aspirate and targeted biopsy of the humeral head excluded blast cell crisis, in contrast to previously reported cases.

Student Motivation in High School Physical Education: A Latent Profile Analysis Approach.

Guided by the principles of self-determination theory, the purpose of this study was to identify latent profiles representing high school students' motivational regulations for physical education (PE) and to model putative predictors and outcomes of profile membership. A sample of 532 Australian high school students, age 12-16 years (M = 13.83, SD = 1.

Testing a continuum structure of self-determined motivation: A meta-analysis.

Self-determination theory proposes a multidimensional representation of motivation comprised of several factors said to fall along a continuum of relative autonomy. The current meta-analysis examined the relationships between these motivation factors in order to demonstrate how reliably they conformed to a predictable continuum-like pattern. Based on data from 486 samples representing over 205,000 participants who completed 1 of 13 validated motivation scales, the results largely supported a continuum-like structure of motivation and indicate that self-determination is central in explaining human motivation.

Trunk extensor fatigue decreases jump height similarly under stable and unstable conditions with experienced jumpers.

Purpose: The purpose of this study was to investigate the effects of back extensor fatigue on performance measures and electromyographic (EMG) activity of leg and trunk muscles during jumping on stable and unstable surfaces.

Methods: Before and after a modified Biering-Sorensen fatigue protocol for the back extensors, countermovement (CMJ) and lateral jumps (LJ) were performed on a force plate under stable and unstable (balance pad on the force plate) conditions. Performance measures for LJ (contact time) and CMJ height and leg and trunk muscles EMG activity were tested in 14 male experienced jumpers during 2 time intervals for CMJ (braking phase, push-off phase) and 5 intervals for LJ (-30 to 0, 0-30, 30-60, 60-90, and 90-120 ms) in non-fatigued and fatigued conditions.

Exploring the feasibility of dose escalation positron emission tomography-positive disease with intensity-modulated radiation therapy and the effects on normal tissue structures for thoracic malignancies.

The pattern of failure is one of the major causes of mortality among thoracic patients. Studies have shown a correlation between local control and dose. Intensity-modulated radiation therapy (IMRT) has resulted in conformal dose distributions while limiting dose to normal tissue.
