Standing and sidelying external rotation exercises produce high activation of the deltoid and infraspinatus. Holding a towel roll under the arm at 30° shoulder abduction during these exercises may decrease deltoid activity and increase infraspinatus activity. The objective was to determine if the addition of a towel under the arm during standing and sidelying external rotation affects EMG activity of the infraspinatus, middle and posterior deltoid, and pectoralis major, compared to the no towel condition. 20 male volunteers (age; 26 ± 3, height; 1.80 m ± .07 m, weight; 77 kg ± 10 kg) had right dominant hand, bilaterally healthy shoulders with no current cervical pathology, and no skin infection or lesion of the shoulder. Maximal voluntary isometric contraction for the infraspinatus, middle and posterior deltoid, and pectoralis major and external rotation in standing and sidelying with and without a towel roll were performed. Normalized average and peak EMG amplitude was compared between the towel conditions during standing and sidelying external rotation. Both infraspinatus and pectoralis major activity had no significant differences between the towel conditions in standing and sidelying (P > .05). In standing and sidelying, posterior deltoid activity was significantly greater with a towel roll (.008 ≤ P ≤ .035 and .008 ≤ P ≤ .018, respectively). Middle deltoid activity had no significant differences between the towel conditions in standing (P > .05). However, in sidelying, middle deltoid activity was significantly lower with a towel roll (.011 ≤ P ≤ .000). The only muscle activation change during standing external rotation with the application of a towel roll was an increase of the posterior deltoid. During sidelying external rotation, holding a towel roll decreased middle deltoid activity and increased posterior deltoid activity. Thus, this study indicates that holding a towel roll under the arm during standing external rotation exercise does not appear to produce desired effects on muscle activation. However, application of a towel roll under the arm could be recommended during sidelying external rotation exercise in order to possibly reduce the superior glide of the humerus, due to decrease muscle activation of the middle deltoid.

Background: PostureScreen Mobile® is an app created to quickly screen posture using front and side-view photographs. There is currently a lack of evidence that establishes PostureScreen Mobile® (PSM) as a valid measure of posture. Therefore, the purpose of this preliminary study was to document the validity and reliability of PostureScreen Mobile® in assessing static standing posture. Methods: This study was an experimental trial in which the posture of 50 male participants was assessed a total of six times using two different methods: PostureScreen Mobile® and Vicon 3D motion analysis system (VIC). Postural deviations, as measured during six trials of PSM assessments (3 trials with and 3 trials without anatomical markers), were compared to the postural deviations as measured using the VIC as the criterion measure. Measurement of lateral displacement on the x-axis (shift) and rotation on the y-axis (tilt) were made of the head, shoulders, and hips in the frontal plane. Measurement of forward/rearward displacement on the Z-axis (shift) of the head, shoulders, hips, and knees were made in the sagittal plane. Validity was evaluated by comparing the PSM measurements of shift and tilt of each body part to that of the VIC. Reliability was evaluated by comparing the variance of PSM measurements to the variance of VIC measurements. The statistical model employed the Bayesian framework and consisted of the scaled product of the likelihood of the data given the parameters and prior probability densities for each of the parameters. Results: PSM tended to overestimate VIC postural tilt and shift measurements in the frontal plane and underestimate VIC postural shift measurements in the sagittal plane. Use of anatomical markers did not universally improve postural measurements with PSM, and in most cases, the variance of postural measurements using PSM exceeded that of VIC. The patterns in the intraclass correlation coefficients (ICC) suggest high trial-to-trial variation in posture. Conclusions: We conclude that until research further establishes the validity and reliability of the PSM app, it should not be used in research or clinical applications when accurate postural assessments are necessary or when serial measurements of posture will be performed. We suggest that the PSM be used by health and fitness professionals as a screening tool, as described by the manufacturer. Due to the suspected trial-to-trial variation in posture, we question the usefulness of a single postural assessment.

The participation of advantaged group members in collective action with the disadvantaged group to challenge inequality is crucial to building a social movement. Although prior work has found that an invitation to participate in collective action is a strong predictor of participation, the extent to which advantaged group members are influenced by such invitations is not known. The present research investigates the effect of the race of an inviter (White vs. Black) on Whites’ willingness to participate in collective action for racial justice as a function of their underlying prejudicial attitudes. Study 1 found that greater internal motivation to respond without prejudice (IMS) was associated with greater willingness to participate in collective action for racial justice. Study 2 found a marginal interaction between race and IMS in predicting collective action, such that for Whites high on IMS, a Black (vs. White) inviter evoked greater willingness to participate in collective action; however, this effect was not replicated in Study 3. Instead, Study 3 found that IMS and the Black (vs. White) inviter independently predicted greater willingness for collective action. Study 3 also found initial evidence of conferred psychological standing to explain how inviter’s race shapes collective action. Specifically, a Black (vs. White) inviter was perceived to have greater psychological standing on issues of racial justice, which increased Whites’ personal standing, and subsequently, Whites’ willingness to participate in collective action for racial justice.

The severely neglected subject of Antifederalism is the focal point of this project. As the framing ideology opposed to the ratification of the U.S. Constitution, Antifederalism has not been treated with the same historical care as Federalism, the successful and currently operational ideology. This is both an intellectual and ethical mistake that ignores the role that Antifederalism played in procuring the Bill of Rights, and still plays in the sphere of political dissent. The de facto successors to the Revolutionary mentality, Antifederalists took it upon themselves to conclusively secure the American conception of liberty, already wrested from British hands, from a growing threat—those whom they deemed domestic imperialists. Even Thomas Jefferson, architect of the Declaration of Independence, espoused the principles behind Antifederalism, especially when confronted with those of Hamiltonian Federalism. Moreover, Jefferson’s Revolution of 1800, which gave rise to the Democratic-Republicans, consisted of many former Antifederalists. While wholly relevant and increasingly indispensible, the few studies that do examine Antifederalism fall short of finding or acknowledging its lasting significance, owing to supposed internal dissension, socioeconomic in nature. However, Antifederalists featured ideological unanimity in at least one area: opposition to standing armies. This opposition is evident in both the theoretical (why they were against standing armies) and practical (what to do about it) areas. The imperial legacy of hostility, a historical and lived experience for Americans of the time, drove Antifederalists to make their objections to ratification obvious, of which the standing army issue played the most elemental part. Informed and inspired by this lengthy history of distrust for military forces maintained in time of peace, which included their own Revolution, Antifederalists sought to safeguard their liberties from future encroachments, for future generations. By arguing iii that Antifederalists, regardless of region or class, objected to standing armies, this thesis seeks to elevate Antifederalism to its rightful place in the contexts of political history and the encompassing American tale.

The reclaiming of land can provide for heated controversy between communities. The controversy at the outset may seem simple, but is actually quite complex involving hegemonic factors such as social, political, and economic influence. One such factor is the media. This research examines media coverage via framing in a battle between the United States Navy and the Hawaiian people to claim ownership of a Hawaiian island named Kaho'olawe. This research analyzes 519 newspaper articles from two Hawaiian newspapers--The Honolulu Star Bulletin and The Honolulu Advertiser--over a seven-year period. Six framing devices--advocate, economic, environment, Hawaiian, military, and political--are devised and implemented. This analysis shows that media frames change over time, when a frame changes so does the tone of the article, and each level of article showed different frame usage. For example, the headline of an article tended to use the political frame most. In addition, this analysis is one of the first to examine the use of pictures within each article and between newspapers. The findings suggest that the media's coverage of land debates needs to be examined further to include the use of media frames, quotes, and pictures.

Improving energy efficient lighting is a necessary step in reducing energy consumption.Lighting currently consumes 17% of all U.S. residential and commercial electricity, but a report from the U.S. Office of Energy Efficiency and Renewable Energy projects that switching to LED lighting over the next 20 years will save 46% of electricity used in lighting.GaN LEDs are used for their efficient conversion of electricity to light, but improving GaN efficiency requires optically engineering the chip to extract more light.Total internal reflection limits GaN LED performance since light must approach the chip surface within 23.6° of normal to escape into air.This thesis systematically studies the effect of index of refraction, material thickness, and nano-grating period on light extraction efficiency.An ITO layer is added to the LED surface to increase the critical angle of light, and standing wave analysis is used to optimize material thicknesses.When these results are combined with the best grating period, light output improves by 254% over the unmodified LED.
