EEG and EMG Sensorimotor Measurements to Assess Proprioception Following ACL Reconstruction

The Anterior Cruciate Ligament (ACL) is the primary source of rotational stability in the knee by preventing the tibia from sliding in front of the femur. When the ACL is torn, it typically must be repaired through reconstructive surgery which results in proprioceptive deficiencies in the knee. Proprioception plays an important role in understanding where one’s knee is in space, sensing movement and reacting accordingly. This study examines an alternative method of measuring proprioceptive responses to a stimulus (motion) by using electromyogram (EMG) and electroencephalogram (EEG) signals to observe muscle and brain activity. Two participants (one with an ACL reconstruction and a second with healthy knees) were tested three times over a six week period. Repeated measures allowed for an initial examination of how proprioception may vary over time in an individual with healthy knees and with an ACL reconstruction. This measurement strategy can examine the process of proprioception recovery after an ACL reconstruction. It has the potential to help physicians and physical therapists decide when a person can return to normal or strenuous activity as well as provide insight into whether uninjured patients have a proprioceptive deficit which may indicate an increased risk of injury

CDFIs Stepping into the Breach: An Impact Evaluation—Summary Report

This report summarizes research undertaken by the Carsey School of Public Policy to evaluate impacts of the Community Development Financial Institutions (CDFI) Fund on CDFIs and of the CDFI industry on the people and communities it serves. In summary, we find a variety of evidence indicating that CDFIs are advancing the statutory purposes of the CDFI Fund to promote economic revitalization and community development through the provision of credit, capital and financial services to underserved populations and communities in the United State

CDFIs and Online Business Lending: A Review of Recent Progress, Challenges, and Opportunities

The report, authored by Jack Northrup, Eric Hangen, and Michael Swack, looks at some of the issues CDFIs face as the fintech industry (technology companies involved in lending) grows and begins to target markets served by CDFIs

CDFI industry analysis: summary report

The Carsey Institute, under contract to NeighborWorks® America and the U.S. Department of Treasury\u27s Community Development Financial Institutions (CDFI) Fund, conducted a detailed analysis of a large sample of community development financial institutions (CDFIs) on issues of capitalization, liquidity and portfolio, and risk management by CDFIs from 2005 to 2010. This work is part of the CDFI Fund\u27s Capacity Building Initiative. The purpose of the report is to explore issues of capitalization, liquidity, and portfolio and risk management by CDFIs

Design and fabrication of Rene 41 advanced structural panels

The efficiency was investigated of curved elements in the design of lightweight structural panels under combined loads of axial compression, inplane shear, and bending. The application is described of technology generated in the initial aluminum program to the design and fabrication of Rene 41 panels for subsequent performance tests at elevated temperature. Optimum designs for two panel configurations are presented. The designs are applicable to hypersonic airplane wing structure, and are designed specifically for testing at elevated temperature in the hypersonic wing test structure located at the NASA Flight Research Center. Fabrication methods developed to produce the Rene panels are described, and test results of smaller structural element specimens are presented to verify the design and fabrication methods used. Predicted strengths of the panels under several proposed elevated temperature test load conditions are presented

Extramarital Sexuality, Monogamy, and Mate Poaching: Evolutionary and Societal Forces that Define Sexual Behaviors and Roles for Men and Women

Through the discussion of prevalence of extramarital sexuality (EMS), jealousy, domestic violence, monogamy, marriage, evolutionary theories, and mate poaching, a theme emerges as human sexuality finds a medium between social and cultural constructs and evolutionary constructs within the context of male and female differences. It is suggested that mate poaching has transpired due to monogamy and marriage being the defining factors of human sexual relations where needs are not being met. Also, there exists several significantly diverse sexual roles and behaviors between males and females. Men are more interested in sexual novelty and variety, whereas women are more interested in long-term relationships as assurance of a resource supply for offspring

Shear Bond Strength Comparison between Two Orthodontic Adhesives and Self-Ligating and Conventional Brackets

Objective: To evaluate and compare the shear bond strengths of two adhesives using two types of brackets: a conventional and a self-ligating bracket system. Materials and Methods: Sixty extracted human premolars were collected. The premolars were randomly divided into three groups of 20 teeth. All three groups were direct bonded. Groups 1 and 2 used light-cured adhesive and primer (Transbond XT) with a conventional (Orthos) and a self-ligating bracket (Damon 2), respectively. Group 3 used a light-cured primer (Orthosolo) and a light-cured adhesive (Blūgloo) with a self-ligating bracket (Damon 2). The specimens were stored in distilled water at 37°C for 40 ± 2 hours, after which they were debonded and inspected for Adhesive Remnant Index (ARI) scoring. Results: The mean shear bond strength was 15.2 MPa for group 1, 23.2 MPa for group 2, and 24.8 MPa for group 3. A one-way analysis of variance and post hoc Tukey test showed significant differences in bond strength (P \u3c .001) between group 1 and groups 2 and 3 but no significant difference (P \u3e .05) between groups 2 and 3. A Weibull analysis demonstrated that all three groups provided sufficient bond strength with over 90% survival rate at normal masticatory and orthodontic force levels. A Kruskal-Wallis test showed no significant difference (P \u3e .05) in ARI scores among all three groups. Conclusions: All three groups demonstrated clinically acceptable bond strength. The Damon 2 self-ligating bracket exhibited satisfactory in vitro bond strength with both adhesive systems used
