Wheelchair Modification

This document outlines the design process for a wheelchair modification. This wheelchair modification is the Senior Capstone Project for five undergraduate students studying Biomedical Engineering at The University of Akron, Team 14. The team was directed to compose a team name, which was chosen to be EnGenious Design Solutions (EDS). The project was provided by Dr. James Keszenheimer who is a professor at The University of Akron. This document focuses on the project results as well as business conclusions

Political Theory, Political Science, And The End Of Civic Engagement

Within a span of fifteen years civic engagement has become a cottage industry in political science and political theory, but the term has now outlived its usefulness and exemplifies Giovanni Sartori\u27s worry about conceptual stretching. This article traces civic engagement\u27s ascension as a catch-all term for almost anything that citizens might happen to do together or alone, and illustrates the confusion that its popularity has occasioned. It proposes that civic engagement meet a well-deserved end, to be replaced with a more nuanced and descriptive set of engagements: political, social, and moral. It also examines the appeal of engagement itself, a term that entails both attention and energy. Attention and energy are the mainsprings of politics and most other challenging human endeavors. But they can be invested politically, or in associative pursuits, or in moral reasoning and follow-through, and those types of engagement can, but need not, coincide. We should be asking which kinds of engagement-which kinds of attention and energetic activity-make democracy work, and how they might be measured and promoted

Mapping interactions with the chaperone network reveals factors that protect against tau aggregation.

A network of molecular chaperones is known to bind proteins ('clients') and balance their folding, function and turnover. However, it is often unclear which chaperones are critical for selective recognition of individual clients. It is also not clear why these key chaperones might fail in protein-aggregation diseases. Here, we utilized human microtubule-associated protein tau (MAPT or tau) as a model client to survey interactions between ~30 purified chaperones and ~20 disease-associated tau variants (~600 combinations). From this large-scale analysis, we identified human DnaJA2 as an unexpected, but potent, inhibitor of tau aggregation. DnaJA2 levels were correlated with tau pathology in human brains, supporting the idea that it is an important regulator of tau homeostasis. Of note, we found that some disease-associated tau variants were relatively immune to interactions with chaperones, suggesting a model in which avoiding physical recognition by chaperone networks may contribute to disease

Evidence of multiple paternity and cooperative parental care in the so called monogamous silver arowana Osteoglossum bicirrhosum (Osteoglossiformes: Osteoglossidae)

Monogamy is rare in fishes and is usually associated with elaborate parental care. When parental care is present in fishes, it is usually the male that is responsible, and it is believed that there is a relationship between the high energetic investment and the certainty of paternity (except in the case of sneaker males). Osteoglossum bicirrhosum is considered a monogamous fish, and has particular behavioral traits that permit the study of mating systems and parental care, such as male mouthbrooding. We investigated the genetic relationships of males with the broods found in their oral cavities in Osteoglossum samples collected in a natural environment in the lower Purus river basin, Amazonas, Brazil. Fourteen broods were analyzed for parentage (268 young and 14 adult males) using eight microsatellite loci. The results indicate that eleven broods show a monogamous system. In one brood, however, approximately 50% of the young were genetically compatible with being offspring of another male, and in another two broods, none of the subsampled young were compatible with the genotypes of the brooding male. The result of this first brood may be explained by the extra-parental contribution of a sneaker male, whereas cooperative parental care may explain the result in the other two broods

Immigrant Political Participation in Europe: Comparing Different Forms of Political Action Across Groups

This paper compares participation in different forms of political action between natives,immigrants and non-citizen immigrants using data from thirteen European countries across six waves of the European Social Survey. The authors highlight problems associated with previous categorizations of political action, and find that when political action is disaggregated and relative participation between groups is examined, that immigrants’ patterns of participation are not substantially different from those of natives. When comparing citizen immigrants to non-citizen immigrants, previous research has suggested that citizenship acts as a “ticket” to non-institutional, unconventional, confrontational forms of political action. The authors’ findings instead suggest a more complicated relationship between immigrant/citizenship status and preferences for political action since citizenship may facilitate participation in both so-called institutional and extra-institutional activities depending on the context of action
