The Impact

Water polo has recently encountered extensive challenges, including possible banishment from the Olympics. To meet the challenges, major rule changes have been implemented. This perspective is to provide a literature review of the impact of rule changes on water polo gameplay. An emerging and relatively small body of research has demonstrated significantly enhanced game dynamics and outcomes as intended by recent rule changes. The water polo community needs more analytical research on the impact of the latest rule changes approved in 2018.

The Impact

This research aimed to identify a change in the dynamics of the water polo game related to identifying differences in the number of goals scored before and after the introduction of the current 2019 rules. The sample analyzed 96 matches from the 2018 and 2020 European Water Polo Championships. The sample of variables included five variables for both subsamples, which referred to the total number of goals scored in the match, as well as the total number of goals per quarter. By applying the T-test for small independent samples, it was determined that at a statistically significant level, a higher number of goals was achieved in the third and fourth quarters, as well as the total number of goals in the 2020 European Championship in Hungary, compared to the 2018 European Championship in Spain. No statistically significant differences were found in the variables related to the total number of goals in the first and second quarters of the water polo match. The rule change, which came into force in 2019, was driven by changes in the game that directly reflected in a more dynamic game that resulted in more goals per game as well as in the final quarter of the game. These changes were undoubtedly preceded by changes in the total number of attacks, faster swimming, more frequent shots, which should definitely be determined by additional research.

Abstract. Given a consistent interest in comparing achievement across sub-populations in international assessments such as TIMSS, PIRLS, and PISA, it is critical that sub-population achievement is estimated reliably and with sufficient precision. As such, we systematically examine the limitations to current estimation methods used by these programs. Using a simulation study along with empirical results from the 2007 cycle of TIMSS, we show that a combination of missing and misclassified data in the conditioning model induces biases in sub-population achievement estimates, the magnitude and degree to which can be readily explained by data quality. Importantly, estimated biases in sub-population achievement are limited to the conditioning variable with poor-quality data while other sub-population achievement estimates are unaffected. Findings are generally in line with theory on missing and error-prone covariates. The current research adds to a small body of literature that has noted some of the limitations to sub-population estimation.

The Impact

Promoting the ratification of the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) was a key objective of the transnational women's movement of the 1980s and 1990s. Yet, few studies examine what factors contribute to ratification. The small body of literature on this topic comes from a world-society perspective, which suggests that CEDAW represented a global shift toward women's rights and that ratification increased as international NGOs proliferated. However, this framing fails to consider whether diffusion varies in a stratified world-system. I combine world-society and world-systems approaches, adding to the literature by examining the impact of women's and human rights transnational social movement organizations on CEDAW ratification at varied world-system positions. The findings illustrate the complex strengths and limitations of a global movement, with such organizations having a negative effect on ratification among core nations, a positive effect in the semiperiphery, and no effect among periphery nations. This suggests that the impact of mobilization was neither a universal application of global scripts nor simply representative of the broad domination of core nations, but a complex and diverse result of civil society actors embedded in a politically stratified world.

The Impact

A review of the literature on the stages of the formation of temporary and permanent occlusion has been performed. This stages play an important role not only for the full development of the maxillofacial apparatus, temporomandibular joint, but also the whole organism. The role of early tooth extraction in the formation of the physiological state of the dentoalveolar system is considered. The conclusion is drawn about the need for a deeper study of this problem in the structure of general dental morbidity.

Khmer Girl’s in Action is a nonprofit that successfully utilizes community-based participatory research (CBPR) with university partners to create social change for youth in Long Beach, CA. Based on semi-structured interviews and content analysis of news articles, I explore the impact and sustainability of this research work and the research partnerships. Findings highlight impacts such as youth empowerment, heightened awareness around community needs, policy change, and CBPR curriculum improvements in the field as impacts. Sustainability requires integrating research into program funding, utilizing a tailored training curriculum, building on community members prior relationships, and selecting partners that share common goals, levels of commitment, and flexibility. As funders demand more data to justify community needs, understanding more examples of such work in the Asian American community will be useful for informing future partnerships.

The Impact

Background: Health Systems routinely make investments in clinically driven outreach programs to build for future community needs, improve health outcomes, and serve their community mission. Many community sports programs have limited access to sports medicine care, including access to athletic trainers. Hypothesis/Purpose: The primary purpose of this study was to evaluate the impact of a clinically integrated Certified Athletic Trainer (ATC) Community Sports Outreach Program, by evaluating the outreach into the community, sports clubs, schools, covered events. Methods: The ATC Community Outreach Program monitored key metrics over a 3 and 1/2-year period. Metrics included the partnerships developed with local clubs and schools, number of athletes covered in each organization, games covered and hours spent supporting organizations. Categories were divided into fiscal years (FY) running from September to August. Fiscal Year 2016 was calculated from January – August, as it was the first year of the program. The percentage of growth of the amount of games covered was calculated from the adjacent FY. Results: Over the first 3 and 1/2 years (FY2016-FY2019), the number clubs, schools, programs covered grew from 10, 19, 25, to 31 from FY2016 - FY2019. Number of athletes from 7,363, 12,552, 15,104, to 19,794 from FY2016 - FY2019. The number of community outreach events grew from 6, 11, 57, to 190 from FY2016 - FY2019 (Table/Figure 1.1). The percentage of growth of games covered grew from 183%, 518% to 333% between FY2016 and FY2019. Discussion/Conclusion: Building, maintaining a sports medicine practice is a complex undertaking, and represents a significant investment for the health system and community. In many communities, access to sports medicine care for athletes is very limited. A clinically integrated ATC program can generate a significant impact on the community by building relationships with local sports clubs/schools and improving sports medicine care access to young athletes.
