Attention Restoration Theory in Gaming as it Pertains to Subsequent Academic Learning

This thesis addresses how attention restoration pertains to subsequent academic learning and whether natural video game settings facilitate attention restoration like physical environments. The researcher hypothesized that participants who played in a virtual nature setting of a video game would perform better on a comprehension test and obtain greater improvements on the SART from pretest to posttest than the simulated urban group. In addition, the experimenter expected the nature group to perform better on both of the aforementioned measures when given 15 min to play rather than 5 min. Finally, it was hypothesized that improvement on the SART would be positively correlated with performance on the comprehension test. However, these hypotheses were not supported by the results of this study. This thesis concludes with reasons for the lack of support, such as the apparent failure of the SART to adequately deplete participant attention, and offers several future directions for research

Athletic pubalgia and associated rehabilitation

BACKGROUND: Evaluation and treatment of groin pain in athletes is challenging. The anatomy is complex, and multiple pathologies often coexist. Different pathologies may cause similar symptoms, and many systems can refer pain to the groin. Many athletes with groin pain have tried prolonged rest and various treatment regimens, and received differing opinions as to the cause of their pain. The rehabilitation specialist is often given a non-specific referral of groin pain or sports hernia. The cause of pain could be as simple as the effects of an adductor strain, or as complex as athletic pubalgia or inguinal disruption. The term sports hernia is starting to be replaced with more specific terms that better describe the injury. Inguinal disruption is used to describe the syndromes related to the injury of the inguinal canal soft tissue environs ultimately causing the pain syndrome. The term athletic pubalgia is used to describe the disruption and/or separation of the more medial common aponeurosis from the pubis, usually with some degree of adductor tendon pathology. TREATMENT: Both non-operative and post-operative treatment options share the goal of returning the athlete back to pain free activity. There is little research available to reference for rehabilitation guidelines and creation of a plan of care. Although each surgeon has their own specific set of post-operative guidelines, some common concepts are consistent among most surgeons. Effective rehabilitation of the high level athlete to pain free return to play requires addressing the differences in the biomechanics of the dysfunction when comparing athletic pubalgia and inguinal disruption. CONCLUSION: Proper evaluation and diagnostic skills for identifying and specifying the difference between athletic pubalgia and inguinal disruption allows for an excellent and efficient rehabilitative plan of care. Progression through the rehabilitative stages whether non-operative or post-operative allows for a focused rehabilitative program. As more information is obtained through MRI imaging and the diagnosis and treatment of inguinal disruption and athletic pubalgia becomes increasingly frequent, more research is warranted in this field to better improve the evidence based practice and rehabilitation of patients.

Sports Hernia/Athletic Pubalgia Among Women

© The Author(s) 2018. Background: “Athletic pubalgia,” a term that has gained acceptance over “sports hernia,” is more common in men than women; however, it represents a significant source of morbidity for patients of both sexes. Inconsistent terminology surrounding this entity poses a diagnostic challenge and makes studying the populations at risk difficult. Purpose: To review a case series of women with athletic pubalgia by analyzing their presentations, concomitant pathologies, and surgical outcomes. Study Design: Case series; Level of evidence, 4. Methods: Between 2013 and 2016, 197 patients were seen and evaluated for the diagnosis of athletic pubalgia. Eighteen patients seen during this time were women. All patients received “pubalgia protocol” magnetic resonance imaging and subsequent surgical intervention for their pathologies. Outcomes among 17 women were assessed with a patient questionnaire \u3e1 year after surgery. Results: Of the 17 women, 9 had rectus aponeurotic plate injury only, or pure athletic pubalgia; the remaining 8 had athletic pubalgia in combination with ≥1 inguinal, obturator, and femoral hernias. Regarding female patients in both groups, 88.2% reported that the surgery was a success at follow-up. Conclusion: Surgical repair of athletic pubalgia among women is successful in dramatically reducing pain levels in this important subset of patients

Radiographic and surgical findings of type I obturator hernias in patients with refractory groin pain

© 2019 Elsevier Inc. Groin pain is a common complaint in the general population, with an underlying etiology that may be difficult to diagnose. Although uncommon, type I obturator hernias may be a significant source of chronic or refractory groin pain. In this review, we discuss the commonly missed findings of type I obturator hernias at CT and MRI, as well as correlate these findings with images obtained at the time of laparoscopic repair

Visualizing MOF Mixed Matrix Membranes at the Nanoscale: Towards Structure-Performance Relationships in CO 2 /CH 4 Separation Over NH 2 -MIL-53(Al)@PI

Mixed matrix membranes (MMMs) composed of metal organic framework (MOF) fi llers embedded in a polymeric matrix represent a promising alternative for CO 2 removal from natural gas and biogas. Here, MMMs based on NH 2 -MIL-53(Al) MOF and polyimide are successfully synthesized with MOF loadings up to 25 wt% and different thicknesses. At 308 K and ? P = 3 bar, the incorporation of the MOF fi ller enhances CO 2 permeability with respect to membranes based on the neat polymer, while preserving the relatively high separation factor. The rate of solvent evaporation after membrane casting proves key for the fi nal confi guration and dispersion of the MOF in the membrane. Fast solvent removal favours the contraction of the MOF structure to its narrow pore framework confi guration, resulting in enhanced separation factor and, particularly, CO 2 permeability. The study reveals an excellent fi llerpolymercontact, with ca. 0.11% void volume fraction, for membranes based on the amino-functionalized MOF, even at high fi ller loadings (25 wt%). By providing precise and quantitative insight into key structural features at the nanoscale range, the approach provides feedback to the membrane casting process and therefore it represents an important advancement towards the rational design of mixed matrix membranes with enhanced structural features and separation performance.ChemE/Chemical EngineeringApplied Science
