Innovations for ISS Plug-In Plan (IPiP) Operations

Limited resources and increasing requirements will continue to influence decisions on ISS. The ISS Plug-In Plan (IPiP) supports power and data for utilization, systems, and daily operations through the Electrical Power System (EPS) Secondary Power/Data Subsystem. Given the fluid launch schedule, the focus of the Plug-In Plan has evolved to anticipate future requirements by judicious development and delivery of power supplies, power strips, Alternating Current (AC) power inverters, along with innovative deployment strategies. A partnership of ISS Program Office, Engineering Directorate, Mission Operations, and International Partners poses unique solutions with existing on-board equipment and resources

Canada’s Looming Retirement Challenge: Will Future Retirees Be Able to Maintain Their Living Standards upon Retirement?

A key question in Canada’s pensions debate is whether Canadians will be able to maintain their living standards in retirement, and if policy needs to respond to the risk that some will experience painful declines.To date, it has been very difficult to estimate how current trends might affect various members of the population in the long run. In this study, we used LifePaths – a sophisticated simulation tool developed at Statistics Canada which integrates a large amount of data on the socio-economic experience of Canadians – to project consumption before and after retirement for Canadians who have not yet reached retirement age. Consistent with other research, the study finds that Canada’s retirement system has supported post-retirement consumption relatively well, especially for lower-income individuals and those who reached retirement age in the last twenty years. If ongoing behavior and economic circumstances were to persist indefinitely, however, more Canadians may find maintaining their working-life consumption in retirement more difficult.Pension Papers, Canada, pensions, retirement income, LifePaths, Statistics Canada, registered pension plans (RPPs), registered retirement savings plans (RRSPs)

Get the Power You Need, When and Where You Need It Aboard the International Space Station (ISS) Using the ISS Plug-In Plan (IPiP) Requirement Request Process

Trying to get your experiment aboard ISS? You likely will need power. Many enditem providers do. ISS Plug-In Plan (IPiP) supports power and data for science, Payloads (or Utilization), vehicle systems, and daily operations through the Electrical Power System (EPS) Secondary Power/Data Subsystem. Yet limited resources and increasing requirements continue to influence decisions on deployment of ISS end items. Given the fluid launch schedule and the rapidly- increasing number of end item providers requiring power support, the focus of the Plug-In Plan has evolved from a simple FIFO recommendation to provide power to end item users, to anticipating future requirements by judicious development and delivery of support equipment (cables, power supplies, power strips, and alternating current (AC) power inverters), employing innovative deployment strategies, and collaborating on end item development. This paper describes the evolution of the ISS Program Office, Engineering Directorate, Flight Operations Directorate (FOD), International Partners and the end item provider relationship and how collaboration successfully leverages unique requirements with limited on- board equipment and resources, tools and processes which result in more agile integration, and describes the process designed for the new ISS end item provider to assure that their power requirements will be met

Connecting Over Coffee: Extending Library Services for Students Through New Campus Partnerships

One meeting with potential partners on campus can turn into a new, exciting initiative to reach underrepresented and first-generation college students. Librarians at a small, private liberal arts college will share how they collaborated with the Office of Multicultural Engagement on their campus to provide reference services to students outside of the library. Emphasis was focused on serving first year students from underrepresented groups, however, the service was open to and used by students from a variety of backgrounds and class years. The speakers will share lessons learned, plans for future development, and assessment strategies

“Lattes with a Librarian”: Collaborating with Campus Partners to Offer Reference Services

Librarians met with colleagues in the Office of Multicultural Engagement (OME) to discuss new opportunities to support student initiatives. Lattes with a Librarian was proposed as a way to provide reference services for students outside of the library. Six dates during the fall semester were selected where a librarian would offer reference services for an hour in the College Union Building

Tubulin cofactors and Arl2 are cage-like chaperones that regulate the soluble αβ-tubulin pool for microtubule dynamics.

Microtubule dynamics and polarity stem from the polymerization of αβ-tubulin heterodimers. Five conserved tubulin cofactors/chaperones and the Arl2 GTPase regulate α- and β-tubulin assembly into heterodimers and maintain the soluble tubulin pool in the cytoplasm, but their physical mechanisms are unknown. Here, we reconstitute a core tubulin chaperone consisting of tubulin cofactors TBCD, TBCE, and Arl2, and reveal a cage-like structure for regulating αβ-tubulin. Biochemical assays and electron microscopy structures of multiple intermediates show the sequential binding of αβ-tubulin dimer followed by tubulin cofactor TBCC onto this chaperone, forming a ternary complex in which Arl2 GTP hydrolysis is activated to alter αβ-tubulin conformation. A GTP-state locked Arl2 mutant inhibits ternary complex dissociation in vitro and causes severe defects in microtubule dynamics in vivo. Our studies suggest a revised paradigm for tubulin cofactors and Arl2 functions as a catalytic chaperone that regulates soluble αβ-tubulin assembly and maintenance to support microtubule dynamics

ASSOCIATIONS BETWEEN CLINICAL AND PERFORMANCE TESTS IN SOCCER ATHLETES

The purpose of this study was to determine the relationship between selected Functional Movement Screen (FMS™) scores, quadriceps and hamstrings strength, and vertical jump performance to see if there is consistency between clinical and performance testing. Records for twelve NCAA-I female soccer players were selected for this study. The isolated scores from the hurdle step and deep squat portions of the FMS™ test were extracted, left and right peak knee extension and flexion torques from isokinetic tests at 60, 180, and 300 °/sec, and vertical jump heights were recorded. Bivariate correlations and a multiple regression analysis were conducted to explore relationships among variables. The results from this study indicated that the FMS™ test was a poor predictor of vertical jump height, but peak extension and flexion torques were related to the vertical jump in a complex relationship
