A Study Of The Stock Market Crash Of October 1987

This study examines the situation surrounding the stock market crash of 1987. The research was conducted in current literature and government reports. The goal of the study is to provide a background on the operations of the stock markets, examine factors leading to and contributing to the crash of 1987, and compare the crash of 1987 to the crash of 1929 in order to provide possible insight to weaknesses in the market system. The conclusions support specific recommendations that are designed to correct market inefficiencies. These recommendations include increasing margin requirements on index futures, monitoring the performance of specialists, and giving the same precedence to all market orders, regardless of size

Localized shear generates three-dimensional transport

Understanding the mechanisms that control three-dimensional (3D) fluid transport is central to many processes including mixing, chemical reaction and biological activity. Here a novel mechanism for 3D transport is uncovered where fluid particles are kicked between streamlines near a localized shear, which occurs in many flows and materials. This results in 3D transport similar to Resonance Induced Dispersion (RID); however, this new mechanism is more rapid and mutually incompatible with RID. We explore its governing impact with both an abstract 2-action flow and a model fluid flow. We show that transitions from one-dimensional (1D) to two-dimensional (2D) and 2D to 3D transport occur based on the relative magnitudes of streamline jumps in two transverse directions.Comment: Copyright 2017 AIP Publishing.

Special issue: Illuminating occupations at the heart of social problems

As this special issue of the Journal of Occupational Science goes to press, the timing seems particularly pertinent to consider the intersection between how society and the rise of social problems impact upon and are influenced by the occupational lives that people, as individuals and collectives, lead. It seems that in all domains of life - work, school, home, leisure, and others - people are having to navigate the challenges of adapting their current occupations or adapting to new occupations as they seek to maintain the health and well-being of themselves and those around them. It is in times of such uncertainty that the complexity of occupation, as central to social life, becomes more visible to a range of societal actors. Drawing on liberatory pedagogical theory in occupation-based learning, Simaan illuminates a classroom activity using his research on occupations associated with olive growing in Palestine

Discrimination and the Implicit Association Test

Prejudice researchers have been criticized for failing to assess behaviors that reflect overtly hostile actions (i.e. racial animus; Arkes & Tetlock, 2004; Mackie & Smith, 1998). Two studies sought to begin to fill this gap in the implicit literature by showing that scores on the Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998) are linked to harmful intergroup behaviors. In Study 1, the IAT predicted self-reported racial discrimination, including verbal slurs, exclusion, and physical harm. In Study 2, the IAT predicted recommended budget cuts for Jewish, Asian, and Black student organizations (i.e. economic discrimination). In each study, evaluative stereotype (but not attitude) IATs predicted behaviors even after controlling for explicit attitudes. In concert, the findings suggest that implicit stereotypes are more predictive of overtly harmful actions than implicit attitudes in the intergroup relations domain

A protocol paper on the preservation of identity: understanding the technology adoption patterns of older adults with age-related vision loss (ARVL)

There are a growing number of older adults with age-related vision loss (ARVL) for whom technology holds promise in supporting their engagement in daily activities. Despite the growing presence of technologies intended to support older adults with ARVL, there remains high rates of abandonment. This phenomenon of technology abandonment may be partly explained by the concept of self-image, meaning that older adults with ARVL avoid the use of particular technologies due to an underlying fear that use of such technologies may mark them as objects of pity, ridicule, and/or stigmatization. In response to this, the proposed study aims to understand how the decision-making processes of older adults with ARVL, as it relates to technology adoption, is influenced by the negotiation of identity. The study protocol will justify the need for this critical ethnographic study, unpack the theoretical underpinnings of this work, detail the sampling/recruitment strategy, describe the methods which included a home tour, go-along, and semi-structured in-depth interview, as well as the collective approach taken to analyze the data. The protocol concludes by examining the ethical tensions associated with this study, including a focus on the methods adopted as well as the ethical challenges inherent when working with an older adult population experiencing vision loss

Understanding Parkinson’s Through Visual Narratives: “I’m Not Mrs. Parkinson’s”

Although it is accepted that individuals with Parkinson’s disease (PD) must navigate challenges such as receiving their diagnosis, and changing daily occupations, little is known about how they navigate. The purpose of this study is to deepen the current understanding of the experience of living with PD and its implications for occupation through a narrative visual methodology (photo-elicitation). Methods: Six individuals with PD were asked to take photographs and share verbal narrative accounts to illustrate their experience of living with PD. Findings: Results highlight the interrelationship between occupation and identity, as many of the participants stories were interpreted as foregrounding the negotiation of occupation, and how such negotiation shaped their sense of identity. Overall three major themes were identified: (1) Framing the meaning of PD (accepting the disease as part of who they were); (2) Negotiating engagement in occupation (ongoing deliberation whether to continue engaging in certain aspects of life as PD progressed); and (3) Being ready to accept changes that impact personal or social identity (Readiness to accept help and to identify as someone with PD). Conclusion: Attending to insights regarding the lived experience of PD will enhance quality of care through informing an enriched client-centered, occupation-based approach

High-intensity drying processes: Impulse drying. Progress report on furnish evaluations for impulse drying commercialization demonstration

Laboratory and pilot scale experiments were performed to identify potential furnishes and operating parameters for upcoming high-speed pilot scale trials and commercial demonstration of impulse drying of heavy weight grades of paper. Results indicate that hydrodynamic specific surface is highly dependent on sheet formation and prehandling. Mill refined pulp and machine paper were comparable to laboratory prepared samples in regards to permeability and impulse drying. Process variables such as platen surface coating, felt type, felt moisture, and presteaming temperature profiles were investigated. Substantial improvements in sheet smoothness were achieved

Fishing For Food: Values and Benefits Associated With Coastal Infrastructure

While there is substantial literature about the socio-cultural characteristics and values associated with recreational and commercial fisheries in the U.S., studies directed at those who ‘fish for food’—those who depend on consuming their catch to various degrees—are relatively sparse. Using qualitative data collected through 80 semi-structured interviews with fishers in the summer and fall of 2018 in Carteret County, North Carolina, this study aims to better understand the group of recreational fishers who consume their catch by describing social and cultural dimensions and values associated with fishing for food, examining the role of infrastructure in facilitating access to benefits associated with this activity, and considering how knowledge of existing licensing regulations surrounding subsistence license waivers affect this fishing community. Interviews conducted at free public fishing structures in the region revealed that fishers derive a variety of values and benefits from fishing at these sites, including access to recreation, nutrition, a social community, and mental health benefits, which were found to be negatively impacted by Hurricane Florence in September 2018. We also found an informal economy of sharing catch on- and off-site that extends the reach and benefits facilitated by public infrastructure to people beyond those using it directly. Overall, we call for conceptualizations of ‘fishing for food’ that include aspects that go beyond traditional definitions of ‘subsistence’ or ‘recreational’ fishing such as food security, access, and less obvious social and cultural motivations behind the activity. These findings are a compelling rationalization for the creation and maintenance of formal and informal fishing places locally and, by extension, in other coastal areas, given the array of benefits provided by access to these types of locations
