    The purpose of this project was to design and develop a Model Playground Behavior Program for elementary-level students in the Cashmere School District, Cashmere, Washington. To accomplish this purpose, current research and literature on playground safety and programs were reviewed. Additionally, related information from selected school districts was obtained and analyzed for possible ideas or practices to be included in the model playground program

    The Distribution and Abundance of the Bay Anchovy, Anchoa mitchilli, in a Southeast Texas Marsh Lake System

    A one-year distribution and abundance study on the bay anchovy, Anchoa mitchilli, was conducted in a southeast Texas marsh-lake system from March 1990 through February 1991. Day and night collections were conducted in backwaters, lake shores, and lake centers by seining and trawling. Bay anchovies were the second most abundant fish species collected, and exhibited seasonal, diet and habitat variations in abundance and distribution. Across the study area, seasonal abundance peaks occurred in May and August following migration into the marsh and seasonal recruitment. However, within each habitat type, peaks of abundance varied in time of occurrence. Within habitats, significant differences in the mean number of anchovies occurred such that backwaters in the daytime had the greatest number followed by backwaters at night, lake shores in the daytime, and lake shores at night. Lake center collections showed no significant diel pattern. The presence of vegetation was associated with reduced anchovy numbers; however, when present, anchovies were significantly more abundant in the daytime than at night

    Design and Evaluation of a Wearable System for Facial Privacy

    Through the increasingly common use of devices that provide ubiquitous sensor data such as wearables, mobile phones, and Internet-connected devices of the sort, privacy challenges are becoming even more significant. One major challenge that requires more focus is bystanders\u27 privacy, as there are too few solutions that solve the issue. Of the solutions available, many of them do not give bystanders a choice in how their private data is used, Bystanders\u27 privacy has become an afterthought when it comes to data capture in the forms of photographs, videos, voice recordings, etc. and continues to remain that way. This thesis provides a solution to enhance bystanders\u27 facial privacy by developing a wearable device called FacePET that provides a way for bystanders to protect their privacy and give consent. FacePET was evaluated using experiments to detect faces in photos when users wore the device and by performing a usability study with 21 participants. We found that FacePET was successfully able to block 15 of the 21 participants\u27 faces, yielding a success percentage of 71%. We found through the usability study that a majority of the participants would be willing to use FacePET, or a similar device, daily for their facial privacy protection

    Examining the link between education related outcomes and student health risk behaviours among Canadian youth: Data from the 2006 National Youth Smoking Survey

    This study examined whether student tobacco, alcohol, marijuana use and sedentary behaviour were associated with the educational outcomes of health-related absenteeism, truancy, and academic motivation in a nationally representative sample of Canadian youth. Descriptive analyses indicate a high proportion of students missed school due to health, and skipped class in the last month. Truancy increased with age, and male students are more likely to skip class, and be less academically motivated. Logistic regression models showed significant associations exist between substance use and all three educational outcomes. These findings support the need for coordinated action and funding in student health promotion.    Keywords: Adolescent, Youth, Truancy, Absenteeism, Academic Motivation, Tobacco, Marijuana, Alcohol Cette étude a examiné si le tabac, l'alcool, la consommation de marijuana, et le comportement sédentaire d'étudiants ont été associés à la réussite scolaire de l'absentéisme liés à la santé, l'absentéisme et la motivation scolaire dans un échantillon national représentatif de la jeunesse canadienne. Les analyses descriptives indiquent une forte proportion d'élèves ont manqué l'école pour raison de santé, et ont sauté de classe dans le dernier mois. L'absentéisme augmente avec l'âge, et les étudiants mâle sont plus susceptibles de manquer de classe et d'être moins motivés académiquement. Des modèles de régression logistique ont montré des associations significatives existent entre l'usage des substances et les trois résultats scolaires. Ces résultats confirment la nécessité d'une action coordonnée et de financement dans la promotion de la santé des élèves

    FacePET: Enhancing Bystanders\u27 Facial Privacy with Smart Wearables/Internet of Things

    Get PDF
    Given the availability of cameras in mobile phones, drones and Internet-connected devices, facial privacy has become an area of major interest in the last few years, especially when photos are captured and can be used to identify bystanders’ faces who may have not given consent for these photos to be taken and be identified. Some solutions to protect facial privacy in photos currently exist. However, many of these solutions do not give a choice to bystanders because they rely on algorithms that de-identify photos or protocols to deactivate devices and systems not controlled by bystanders, thereby being dependent on the bystanders’ trust in these systems to protect his/her facial privacy. To address these limitations, we propose FacePET (Facial Privacy Enhancing Technology), a wearable system worn by bystanders and designed to enhance facial privacy. We present the design, implementation, and evaluation of the FacePET and discuss some open research issues

    A User Study of a Wearable System to Enhance Bystanders’ Facial Privacy

    Get PDF
    The privacy of users and information are becoming increasingly important with the growth and pervasive use of mobile devices such as wearables, mobile phones, drones, and Internet of Things (IoT) devices. Today many of these mobile devices are equipped with cameras which enable users to take pictures and record videos anytime they need to do so. In many such cases, bystanders’ privacy is not a concern, and as a result, audio and video of bystanders are often captured without their consent. We present results from a user study in which 21 participants were asked to use a wearable system called FacePET developed to enhance bystanders’ facial privacy by providing a way for bystanders to protect their own privacy rather than relying on external systems for protection. While past works in the literature focused on privacy perceptions of bystanders when photographed in public/shared spaces, there has not been research with a focus on user perceptions of bystander-based wearable devices to enhance privacy. Thus, in this work, we focus on user perceptions of the FacePET device and/or similar wearables to enhance bystanders’ facial privacy. In our study, we found that 16 participants would use FacePET or similar devices to enhance their facial privacy, and 17 participants agreed that if smart glasses had features to conceal users’ identities, it would allow them to become more popular
