Description and preliminary calibration results for the Langley hypersonic CF4 tunnel

A detailed description of the hypersonic CF4 tunnel is presented along with discussion of the basic components, instrumentation, and operating procedure. Operational experience with the CF4 reclaimer and lead-bath heater is discussed. Comparison of measured and predicted shock detachment distance on a sphere and pressure distributions measured on a sharp leading-edge flat plate revealed the absence of significant flow nonuniformity and lent creditability to predicted free stream flow conditions. The economic operation of this facility centers about the CF4 reclaimer, which was designed to operate at an efficiency of 90 to 95 percent. A number of modifications were made to the reclaimer system to improve its performance, and presently, the system reclaims approximately 75 percent of the test gas. Even with current budgetary constraints, this efficiency permits the CF4 tunnel to be operated as a viable research wind tunnel

Help-seeking for cognitive impairment by the patient : the role of self-compassion.

Older adults represent one of the fastest growing population groups with estimates predicting global growth from 617 million in 2015 to 1.6 billion in 2050. As the aged population increases, incidence of Alzheimer’s disease (AD) and other dementias will also increase. Professionals agree that early intervention is essential for therapeutic and quality of life purposes. However, many older adults wait several months or years to seek medical help after first noticing signs of cognitive impairment. The present study seeks to identify the predictors of help-seeking for cognitive impairment by an individual for him/herself and the role that self-compassion may play in this process. Using two approaches, the present study reveals that cognitive (i.e., symptom identification and disease attribution) and affective (i.e., symptom impact and threat appraisal) factors predict help-seeking intentions while also providing evidence that help-seeking intentions may be a separate construct from help-seeking behavior in the context of responding to signs of AD. Contrary to hypotheses, self-compassion did not function as a moderator of help-seeking intentions nor did it significantly predict help-seeking intentions beyond other variables. Consideration is given as to why self-compassion may not have functioned in this process as expected. Self-compassion may have a greater impact on help-seeking actions than the intentions that seem to have been measured by the present study. Recommendations are made for future research to further investigate patients’ help-seeking actions in response to signs of cognitive impairment and to clarify whether or not self-compassion plays a role

Rounding Numbers: Why The \u27\u27new System\u27\u27 Doesn\u27t Work

This paper explains a correction to the rounding rule previously publishedin this Journal. The earlier article reported that the best way to roundnumbers is to always round up when the first digit dropped is 5. However,this will lead to accumulation of error when errors are averaged. Arounding strategy that leads to less error is to round up when 5 isfollowed by any nonzero digits, but to round even when 5 is followed byzeros or no other digits. By rounding the last kept digit to an evennumber, half the time the digit is increased and half the time it is keptthe same so that errors tend to cancel when averaged

Vantage Point and Visual Imagery: Effects on Recall in Younger and Older Adults

The current study explored the influence of priming vantage point at retrieval on the recall of younger and older adults, in addition to the effects of visualization ability on recall. Based on McIsaac and Eich’s (2002) findings of the effects on younger adults’ recall, it was hypothesized that recollections would be more likely to include certain features when retrieved through the field vantage point (FVP) than through the observer vantage point (OVP) and vice-versa. Additionally, it was expected that older adults would recall more detailed memories from the OVP than from the FVP. Finally, it was hypothesized that visualization ability would influence memory vividness and that it would be more influential in older adults than in younger adults. The experiment was conducted across two sessions. In Session 1, participants completed a visual imagery assessment, and memories were created in the laboratory with younger (n = 20; 18-21 years old) and older (n = 18; 63-88 years old) adults through the completion of two activities. In Session 2, participants recalled the activities from either the FVP or the OVP. Participants’ recollections were coded for various memory characteristics, which acted as dependent variables in analyses. A significant interaction effect (p = .003) between age and vantage point was found on the characteristic of psychological state, such that older adults referred to their psychological state in FVP memories more than in OVP memories (p = .002), while younger adults demonstrated no significant difference. Imagery ability significantly predicted several aspects of participants’ subjective recall experience. Overall, the results indicate that retrieval vantage point does not change the content of one’s recollections on most measures for either younger or older adults and that visual mental imagery ability predicts several aspects of one’s recall experience

Feminism in Multicultural Societies: An analysis of Dutch Multicultural and Postsecular Developments and their Implications for Feminist Debates

It was long assumed that both multiculturalism and feminism are connected to progressive movements and hence have comparable and compatible goals. However, both in academia and in popular media the critique on multiculturalism has grown and is often accompanied with arguments related to gender equality and/or feminism. According to political scientist Susan Moller Okin for example there are fundamental conflicts between our commitment to gender equality and the desire to respect the customs of minority cultures or religions. If we agree that women should not be disadvantaged because of their sex, she argues, we should not accept group rights that permit oppressive practices. Okin’s claims led to a complex and highly important debate both in academia and in public debates. The main aim of this thesis is to explore in depth the different discourses about multiculturalism and feminism and develop a more inclusive and nuanced redefinition of the relationship between multiculturalism and feminism. The focus of the analysis will be on the Netherlands, where the debate has been intense and paradigmatic of similar debates in most countries. The first part of the thesis explores the literature on multiculturalism and feminism, and discusses the importance of for instance intersectionality, the politics of location and situated knowledges for a better understanding of the debates. The second part of the thesis is dedicated to fieldwork. A preliminary media analysis is undertaken to analyse the main aspects of the public debate as they appear in the feminist magazine Opzij. On the basis of this analysis, a series of focus groups with women belonging to organisations that are considered stakeholders in the debate (e.g. feminist, religious, cultural or sub-cultural) is organised. The thesis provides a comprehensive understanding of the complex relationship between the concepts of multiculturalism and feminism. It argues that gender equality is often misused in islamophobic and anti-migration discussions, which also harms the position of minority women. Furthermore, it demonstrates that a more nuanced and inclusive interpretation of multiculturalism and feminism acknowledges the multiple layers of this debate, starts from intersectionality and includes critical accounts of secularism and religion, colonial history and subjectivity
