    There is considerable interest in developing a better understanding of the dynamic behavior of heterogeneous materials. This study investigates and compares the dynamic response of 20 and 47% dense aluminum foam systems with and without a polytetrafluoroethylene (PTFE or Teflon) fill. Experiments on 47% foam were conduced in a 60 mm bore gun in a reverse ballistic configuration at velocities ranging from 350 m/s to 2.5 km/s. The particle velocity of the backside of the anvil was monitored with a VISAR system. Mesoscale simulations are in good agreement with the available experimental data. Both the experimental and simulated data are in good agreement with an analytic release isentrope when released from Hugoniot stress levels less than 5 GPa. However there is significant deviation from the analytic isentrope as the Hugoniot stress level is increased

    Lions and Tigers and Bears, Oh My!: The Necessity for Uniform Regulations and Training of Assistance Animals to Curtail Discriminatory and Fraudulent Behaviors Regarding Such Animals

    With the proliferation of service and emotional support animals fulfilling multiple forms of assistance or comfort, “considerable confusion over the meaning of individual terms used to designate the function and role of service animals, assistance animals, therapy animals, and emotional support animals” is understandable. This is further exacerbated by the terms used by differing agencies, organizations, and innumerable statutes that are meant to ensure the right and privilege of the use of these animals. It is no wonder that public perception would be affected. The affectation of public perception is most evident in the determination of the service animal over an emotional support animal or therapy animal in relation to psychiatric disorders. Where a service animal is trained to provide specific support for conditions such as, but not limited to panic attacks, post-traumatic stress disorder (“PTSD”), and obsessive-compulsive disorder (“OCD”) by “carry[ing] out specific tasks to help an individual cope with his/her [sic] disability,” an emotional support animal provides the same sort of assistance but is not required to have specific training. Is this a distinction without a true difference? Public perception would say yes, whereas to enjoy the protections afforded under the ADA the answer would be no. Thus, “[t]hese differences may make it difficult for landlords, business owners, and employers to distinguish between the types of assistance animals.” Due to the myriad of rules, policies, and guidelines relating to the identification and acceptance of service and emotional support animals, it is not surprising that places of public accommodation, private entities, and commercial facilities may run afoul of the ADA. To avoid situations of peacocks and potbelly pigs on airplanes or gerbils at the dinner table, Congress should amend the ADA and set forth a standardized training, registration, and identification process that is otherwise lacking

    Addressing the complexity of climate change through games

    Climate change is one of the main issues of our time and the Intergovernmental Panel on Climate Change has declared the state of global emergency. Although a recent report reveals that the 93% of Europeans see climate change as a serious problem, it seems the issue is not recognized as so urgent by individuals or as something that can be tackled through individual actions. Towards the vast complexity of the phenomenon, the individual feels distant and impotent attributing the main responsibility of implementing effective actions to governments and industries. We believe the change of public attitude at a larger scale is as relevant as the utmost necessary governmental action plans. The present work addresses the topic of climate change in order to encourage the commitment of ordinary people to take care of the environment, enhancing the role that each individual can have locally to impact globally. The thesis focuses on climate as a complex system and tackles specifically the need to master the concepts and mechanisms typical of complexity as a way to foster conscious pro-environmental actions through science education. It is considered relevant the impact on educational approach to forge in the public an adequate mindset oriented towards a new causal logic where the concepts of complexity – such as emergent properties, feedback mechanisms and deterministic chaos – are cognitively accepted and embraced. Amongst the didactic tools developed by researchers in science education, the work focuses on four role-playing activities that have been analyzed in details, in particular to show how the concepts typical of complexity can enhance the role of individuals to tackle the issue of climate change. Indeed, the educational path proposed in this thesis was designed with the big scope to contribute to make people believe in the power of individual actions towards the global change comprehending the true aspects of complexity

    Intergenerational programs in the public schools

    The major purpose of this study was to research intergenerational programs in the public schools. The research was undertaken to establish whether intergenerational programs improve community attitudes and benefit the school systems that provide these programs. A broad base literature search and a database search were conducted. Numerous letters were written to school systems, state and county agencies, volunteer groups, and senior citizen groups that have instituted programs. The responses collected resulted in a compilation of successful programs that can be used by superintendents, community coordinators, and school public relations directors. Several major conclusions were drawn from this study. Activities that brought senior citizens into the schools were more effective in building committed involvement. Successful programs followed similar planning strategies. Programs in which the benefits surpassed expectations were ones that were ongoing and ones in which participants were actively involved. Programs resulted in more positive attitudes and support for schools

    Promoting Occupational Well-Being Through Program Development at Rock Steady Boxing

    This doctoral capstone was completed through a partnership with Rock Steady Boxing (RSB), a non-profit organization which aims to provide hope to people with Parkinson’s Disease and strives to improve quality of life. The goal of this project was to create resources for RSB that support business growth and promote occupational well-being amongst participants. Resources include updated intake assessment forms, workout templates, and an organized Google Drive for storage and dissemination of resources

    TIME AND BIOGRAPHY IN DIABETIC EXPERIENCE

    Get PDF
    This paper offers a preliminary analysis of temporality in the lives of diabetics. It is argued that time unites the various aspects of diabetic experience, including the disease itself, and the social, emotional, institutional, and technological arenas of that experience. A depiction of diabetic experience is rendered by focusing on family life, time in the individuals' sense of being, and biographical time. It is concluded that diabetes transforms time for the person and for patterns ofgroup life
