Women in Community Colleges: Access to Success
This report explores an underappreciated part of our higher education system. The report looks at the role of community colleges in women's education, including challenges women face in completing a certificate or degree, or in transferring to a four-year institution. The particular concerns and needs of student mothers and barriers women face in pursuing STEM and nontraditional fields are examined in detail. The report includes recommendations that will strengthen community colleges for all students
An Investigation of the Large-scale Variability of the Apparently Single Wolf-Rayet Star WR 1
In recent years, much studies have focused on determining the origin of the
large-scale line-profile and/or photometric patterns of variability displayed
by some apparently single Wolf-Rayet stars, with the existence of an unseen
(collapsed?) companion or of spatially extended wind structures as potential
candidates. We present observations of WR 1 which highlight the unusual
character of the variations in this object. Our narrowband photometric
observations reveal a gradual increase of the stellar continuum flux amounting
to Delta v = 0.09 mag followed by a decline on about the same timescale (3-4
days). Only marginal evidence for variability is found during the 11 following
nights.
Strong, daily line-profile variations are also observed but they cannot be
easily linked to the photometric variations.
Similarly to the continuum flux variations, coherent time-dependent changes
are observed in 1996 in the centroid, equivalent width, and skewness of He II
4686. Despite the generally coherent nature of the variations, we do not find
evidence in our data for the periods claimed in previous studies. While the
issue of a cyclical pattern of variability in WR 1 is still controversial, it
is clear that this object might constitute in the future a cornerstone for our
understanding of the mechanisms leading to the formation of largely anisotropic
outflows in Wolf-Rayet stars.Comment: 11 pages, 9 figures, accepted for publication in Astronomy &

The Effect of Power Alternation Frequency During Cycling on Metabolic Load and Subsequent Running Performance
The purpose of this study was to determine whether the frequency of power output alternation during cycling affects subsequent running performance. Eleven male triathletes completed a graded cycle test to determine peak oxygen uptake and the corresponding power at 35% delta. Two performance tests were then conducted, each comprising of a thirty minute cycling protocol followed by a 5 km free pace run. Mean cycling power was equal for both trials (35% delta), however the frequency of power alternations differed. In one trial cycling power output alternated every five minutes, whereas in the other trial cycling power output alternated every one minute. Power was set to alternate 15% above and below the 35% delta value. No significant difference was found between trials for the subsequent 5 km running performance time (P = .63). A significant difference was observed for overall mean heart rate between cycle trials (P = .045), however no significant difference was observed for overall mean oxygen uptake, minute ventilation, respiratory exchange ratio, blood lactate, rating of perceived exertion or pedal cadence (P > 0.05). When data was divided into 5 minute epoch stages rating of perceived exertion was significantly different between cycle trials at epochs three (minutes 10-15; P = .046) and five (minutes 20-25; P < 0.001). We conclude that when power is alternated equally during cycling, the frequency of power change (maximum of five minutes, minimum of one minute) does not affect subsequent running performance
An epidemiological analysis of potential associations between C-reactive protein, inflammation, and prostate cancer in the male US population using the 2009–2010 National Health and Nutrition Examination Survey (NHANES) data
Prostate cancer is the second leading cause of cancer-related deaths in US males, yet much remains to be learned about the role of inflammation in its etiology. We hypothesized that preexisting exposure to chronic inflammatory conditions caused by infectious agents or inflammatory diseases increase the risk of prostate cancer. Using the 2009-2010 National Health and Nutrition Examination Survey, we examined the relationships between demographic variables, inflammation, infection, circulating plasma C-reactive protein (CRP), and the risk of occurrence of prostate cancer in US men over 18 years of age. Using IBM SPSS, we performed bivariate and logistic regression analyses using high CRP values as the dependent variable and five study covariates including prostate cancer status. From 2009 – 2010, an estimated 5,448,373 men reported having prostate cancer of which the majority were Caucasian (70.1%) and were aged 40 years and older (62.7%). Bivariate analyses demonstrated that high CRP was not associated with an increased risk of prostate cancer. Greater odds of having prostate cancer were revealed for men that had inflammation related to disease (OR = 1.029, CI 1.029-1.029) and those who were not taking drugs to control inflammation (OR = 1.330, CI 1.324-1.336). Men who did not have inflammation resulting from non-infectious diseases had greater odds of not having prostate cancer (OR = 1.031, CI 1.030-1.031). Logistic regression analysis yielded that men with the highest CRP values had greater odds of having higher household incomes and lower odds of having received higher education, being aged 40 years or older, being of a race or ethnicity different from other, and of having prostate cancer. Our results show that chronic inflammation of multiple etiologies is a risk factor for prostate cancer and that CRP is not associated with this increased risk. Further research is needed to elucidate the complex interactions between inflammation and prostate cancer

Global perspectives and translations of consuming clothing waste in the present
The mass consumption of clothing has resulted in collection charities such as Oxfam exporting unwanted second hand clothing to markets in the Sub-Saharan region. This is a trade that is seen as supporting sustainable solutions to unwanted clothing but offers ‘both opportunity’ and ‘danger’ to local communities (Haggblade, 2007). The research explores the second hand clothing trade in Ghana, which evidences this danger and challenges the notion of opportunity.
The second hand clothing market whilst benefitting local communities in Africa has also impacted upon local textile production. From our conversations around these issues, a collaborative project idea emerged entitled ‘Return to Sender’. The project aims to highlight and challenge the effects of the second hand clothing market upon local heritage in Africa. A shared perspective through global design stories can encourage designers to understand the consequences of design but at the time same enable them to have the power to impact and drive change of consumer habits. The current and future perspectives of purchasing clothing and re-use is explored, regarding how this could then influence and change the global second hand clothing markets.
This paper also explores the potential of sustainable outcomes through focusing design in the present, rather than the future. In order to understand a global world we need to see the world as it is to solve the problems and in turn prevent problems in the future. We need an approach that is not engrained into a system but something that promotes creativity and openness to change
Health Promotion Project
Nursing students from Seattle Pacific University implemented a demographic and health survey and COVID-19 vaccine information pamphlet for staff and residents at at our assigned agency in Seattle, Washington. Using the nursing process, the nursing students assessed the needs of the agency using the community resources and information from the Resident Service Coordinator, then formed nursing diagnoses based on this reliable information. The nursing students continued the process by using SMART goals to plan for their community health project which included conducting and analyzing a comprehensive health survey of the population for the agency residents so that staff will have resources detailing their residents’ health needs and the opportunity to plan future activities and education that can be better tailored to the residents’ needs (see Appendix A). The nursing students also created a COVID-19 vaccine information pamphlet to provide basic information about the vaccine to appear in the Agencies\u27 monthly newsletter (see Appendix B). These goals were then implemented. The success of the survey project was evaluated by receiving 25% completed surveys. The nursing students were unable to evaluate the staff responsiveness from the health survey results or the success of the COVID-19 vaccine education due to the allotted project timeline but would have done this through a pre-survey and post-survey to evaluate the effectiveness of both education resources
Meeting some challenges of learner diversity by applying modal preference and learning needs to adult learning
Learners’ needs have always been a factor that university teachers should take into account when designing or delivering subject matter. In this paper, some design and delivery strategies are outlined and preliminary assessments of their effectiveness are made. The strategies focus upon the feasible implementation of sound pedagogical and andragogical principles within a framework of modal preference and adult learning needs. The authors did not implement identical strategies in their respective subjects, but had a common objective: to improve learning and assessment outcomes by recognising the different learning needs of different students
Risk Characterization For Introduction And Spread Of Multinucleate Sphere X (Msx) In Prince Edward Island, Canada
Multinucleate Sphere X (MSX) is an important pathogen of the eastern oyster (Crassostrea virginica) on the east coast of North America. This parasite is currently not present in Prince Edward Island (PEI), but there are concerns that it will spread from Cape Breton, Nova Scotia, where it was recently identified. Introduction of MSX to PEI would cause direct losses to the shellfish industry and it would have long-term implications for exports of oysters. The main goal of this study was to assess the risk of introduction and dissemination of MSX, as estimated by the number of movements of commercial oysters from three data sources. The in-degree (incoming) and out-degree (outgoing) of the contact network among bays, estuaries, and rivers were used to quantify the risks. For a single location on PEI, identification of up to 55 incoming and up to 26 outgoing movements to and from different locations within PEI were recorded. This suggests that if MSX was introduced it could be disseminated quickly. Movements of shellfish (oysters and mussels) from New Brunswick and Nova Scotia, which pose additional risks of pathogen introduction to PEI, were also identified. Two locations (New London Bay and the East-North-West River complex) were consistently ranked in the top quartile of incoming movements by the three data sources. In addition, two other locations (Bideford Area and Conway Narrows) were classified in the same quartile by only two of the data sources, suggesting that these four areas can be considered at high risk for pathogen introduction. Similarly, two locations were classified in the top quartile of outgoing movements (East-North-West River complex and Orwell Area) by the three data sources, whereas Bideford Area and Foxley River were only identified by two of the three data sources in the same quartile. These results indicate not only risk areas for pathogen introduction or dissemination, but also those areas having both high risk of introduction and high risk of dissemination (e.g., East-North-West River complex). Results of this study illustrate the potential consequences of MSX should Haplosporidium nelsoni reach PEI. Findings also highlight the need for the development of a system that captures all shellfish movements, which will be essential to mounting an effective response to pathogen introduction and mitigation of disease dissemination
