Ground-water resources of the Oakland Park area of eastern Broward County, Florida

The Oakland Park area obtains its water from the Biscayne aquifer, S composed of very permeable and porous, sandy limestones. The per- 3 meability of the aquifer increases with depth, and wells in the area <\ generally obtain water at depths ranging from 60 to 80 feet, or between S 100 and 200 feet, depending on the quantity of water desired. The data presented in this paper can be used for further development of water and wise management of resources in the area. Large quantities S of ground water are still available at Oakland Park, if salt-water encroachment can be controlled. The data in this study provide the necessary information to begin an effective water management program. (PDF has 49 pages

Three applications for mobile epidemic algorithms

This paper presents a framework for the pervasive sharing of data using wireless networks. 'FarCry' uses the mobility of users to carry files between separated networks. Through a mix of ad-hoc and infrastructure-based wireless networking, files are transferred between users without their direct involvement. As users move to different locations, files are then transmitted on to other users, spreading and sharing information. We examine three applications of this framework. Each of these exploits the physically proximate nature of social gatherings. As people group together in, for example, business meetings and cafés, this can be taken as an indication of similar interests, e.g. in the same presentation or in a type of music. MediaNet affords sharing of media files between strangers or friends, MeetingNet shares business documents in meetings, and NewsNet shares RSS feeds between mobile users. NewsNet also develops the use of pre-emptive caching: collecting information from others not for oneself, but for the predicted later sharing with others. We offer observations on developing this system for a mobile, multi-user, multi-device environment

Effectiveness of Financial Incentives in Improving Breast Cancer Screening Among Medicaid Recipients

Breast cancer remains one of the leading causes of death among women. Roughly 2.4 million women are diagnosed annually with breast cancer throughout the world. Although breast cancer survival rates are favorable for the United States compared to other nations (90% 5-year survival for non-metastatic disease), it comes at a high cost. The United States spends an estimated $30 billion annually on breast cancer treatment. In addition, disparities in breast cancer survival rates also exist in the United States. Women Medicaid recipients, who are predominately minorities (60Significant efforts to improve breast cancer survival while reducing identified disparities and treatment costs have been underway for more than forty years. Advances in healthcare policy have played a critical role in saving lives and increasing access to breast cancer screening in the United States. Breast cancer screening is universally supported among professional societies as a tool to diagnose breast cancer in its earliest stages when it is most treatable. However, breast cancer screening is underutilized among Medicaid recipients, correlating with their higher rates of breast cancer mortality. The passage of the Affordable Care Act (2010) expanded access to health insurance for millions of Americans while allowing Medicaid organizations to compensate their recipients for participating in preventive health behaviors such as breast cancer screening. Financial incentives for preventive health behavior provided by Medicaid organizations have the potential to help cover out-of-pocket costs such as transportation, adult/childcare, or lost wages, as well as encourage Medicaid recipients to prioritize breast cancer screening and/or overcome apprehensions such as physical discomfort and fear of navigating the health care system. Using the Gelberg-Anderson Behavioral Model for Vulnerable Populations, a retrospective quantitative study was conducted to assess the role of financial incentives in the utilization of breast cancer screening among Medicaid recipients (aged 50-64) residing in Baltimore, Maryland. The study aimed to answer the following research questions: One, do financial incentives increase the utilization of breast cancer screening among women with Medicaid aged between 50 and 74 compared to women who do not receive financial incentives? Two, are higher amounts of financial incentives associated with greater utilization of breast cancer screening? Three, what population characteristics are associated with higher utilization of breast cancer screenings among Medicaid recipients when financial incentives are provided? The study included 2,578 unique Medicaid recipients who were not current with their breast cancer screening when applying the US Preventive Services Task Force recommendations (2016). Between 2019 and 2022, 738 breast screening exams were completed. Two cohorts were established in the study. One cohort did not receive a financial incentive (392) for breast cancer screening, and a second cohort did receive a financial incentive (2,186) for breast cancer screening. Logistic regression was the primary statistical tool for answering all three research questions. The dependent variable for all three questions was dichotomous, specifically, was a breast cancer screening claim identified (yes/no)? The predictor variable was the use of financial incentives which had three levels,$75, $100, and$150. Covariates such as age (years), race, geographic sub-region of Baltimore, Maryland for the primary residence, and the number of people reported as living with the Medicaid recipient (household count) were considered when assessing the role of population characteristics and breast cancer screening utilization when a financial incentive was provided. The primary question considered by the study was asking if financial incentives provided to Medicaid recipients increased the utilization of breast cancer screening. The study findings were inconclusive. A secondary question considered if larger-sized financial incentives increased the likelihood of breast cancer screening compared to when a smaller incentive was provided. It was identified that the smaller financial incentive ($75) was statistically significant (p-value \u3c 0.001) for increasing the likelihood of breast cancer screening utilization while the larger financial incentives ($100 or $150) were not found to be statistically significant. The covariates of the Baltimore sub-region and the household count were identified to be not statistically significant in either the financial incentive or no financial incentive cohorts. Alternatively, the age (OR=1.07, 95% CI 1.04, 1.11, p-value \u3c0.05) and race covariates were identified as being statistically significant (p-value \u3c0.05) when a financial incentive was provided to increase breast cancer screening among Medicaid recipients. It was noted that American Indian/Alaskan Native and Black participants who received a financial incentive had a statistically significant (p-value \u3c0.05) increase in their likelihood of utilizing breast cancer screening

Measurement of outflow facility using iPerfusion

Elevated intraocular pressure (IOP) is the predominant risk factor for glaucoma, and reducing IOP is the only successful strategy to prevent further glaucomatous vision loss. IOP is determined by the balance between the rates of aqueous humour secretion and outflow, and a pathological reduction in the hydraulic conductance of outflow, known as outflow facility, is responsible for IOP elevation in glaucoma. Mouse models are often used to investigate the mechanisms controlling outflow facility, but the diminutive size of the mouse eye makes measurement of outflow technically challenging. In this study, we present a new approach to measure and analyse outflow facility using iPerfusion™, which incorporates an actuated pressure reservoir, thermal flow sensor, differential pressure measurement and an automated computerised interface. In enucleated eyes from C57BL/6J mice, the flow-pressure relationship is highly non-linear and is well represented by an empirical power law model that describes the pressure dependence of outflow facility. At zero pressure, the measured flow is indistinguishable from zero, confirming the absence of any significant pressure independent flow in enucleated eyes. Comparison with the commonly used 2-parameter linear outflow model reveals that inappropriate application of a linear fit to a non-linear flow-pressure relationship introduces considerable errors in the estimation of outflow facility and leads to the false impression of pressure-independent outflow. Data from a population of enucleated eyes from C57BL/6J mice show that outflow facility is best described by a lognormal distribution, with 6-fold variability between individuals, but with relatively tight correlation of facility between fellow eyes. iPerfusion represents a platform technology to accurately and robustly characterise the flow-pressure relationship in enucleated mouse eyes for the purpose of glaucoma research and with minor modifications, may be applied in vivo to mice, as well as to eyes from other species or different biofluidic systems

Influence of the public transportation system on the air quality of a major urban center. A case study: Milan, Italy

A sampling campaign was conducted in the city of Milan, Italy before and during a transportation strike in January 2004. This strike provided a unique opportunity to investigate the influence of public transportation on the air quality in a major metropolitan area. Twenty-four air samples were collected each day around the city on January 2nd, 7th and 9th. The samples were analyzed for methane, carbon monoxide, non-methane hydrocarbons (NMHCs), halocarbons and alkyl nitrates. Significant differences in the mixing ratios were observed among the three days of sampling, with January 2nd showing the lowest concentrations as a result of decreased activity in the city during the holiday season. January 9th showed the highest NMHC concentrations because of increased vehicular activity in the city due to a public transportation strike. This paper investigates the correlation between the increased number of vehicles and decreased air quality because of a reduction in public transportation. Computer simulations were able to reproduce measurements of ozone production during the January 2004 strike and a July 2005 strike. The measurements and simulations suggest that reduced VOC emissions due to the existence of public transportation lowers peak ozone by 11-33% during the summer months. © 2008 Elsevier Ltd.

Picking pockets on the lawn: the development of tactics and strategies in a mobile game

This paper presents Treasure, an outdoor mobile multiplayer game inspired by Weiser’s notion of seams, gaps and breaks in different media. Playing Treasure involves movement in and out of a wi-fi network, using PDAs to pick up virtual ’coins’ that may be scattered outside network coverage. Coins have to be uploaded to a server to gain game points, and players can collaborate with teammates to double the points given for an upload. Players can also steal coins from opponents. As they move around, players’ PDAs sample network signal strength and update coverage maps. Reporting on a study of players taking part in multiple games, we discuss how their tactics and strategies developed as their experience grew with successive games. We suggest that meaningful play arises in just this way, and that repeated play is vital when evaluating such games
