    1988-01-01

    This report provides guidance, along with EPA Water Quality Criteria and State Water Quality Standards and other information, to help refine and improve Chesapeake Bay Agreement programs designed to provide for the restoration and protection of living resources, their habitats, and ecological relationships. The Living Resources Task Force, an ad hoc workgroup of the Chesapeake Bay Program, was charged by the Chesapeake Bay Implementation Committee to develop an approach to define habitat objectives for the living resources of the Bay. The report was produced by the Task Force to establish a technically defensible approach in setting regional habitat objectives for Chesapeake Bay by initially assembling habitat requirement for individual target species. It summarizes the results of the Task Force efforts to date and provides the basis for future refinement of the habitat objectives approach.

    2009-01-01

    The Chesapeake Bay Program (CBP) is attempting to more strategically implement management actions to improve the health of the Nation’s largest estuary. In 2007 the U.S. Geological Survey (USGS) and U.S. Environmental Protection Agency (USEPA) CBP office began a joint effort to develop a suite of Internetaccessible decision-support tools and to help meet the needs of CBP partners to improve water quality and habitat conditions in the Chesapeake Bay and its watersheds. An adaptive management framework is being used to provide a structured decision process for information and individual tools needed to implement and assess practices to improve the condition of the Chesapeake Bay ecosystem. The Chesapeake Online Adaptive Support Toolkit (COAST) is a collection of web-based analytical tools and information, organized in an adaptive management framework, intended to aid decisionmakers in protecting and restoring the integrity of the Bay ecosystem. The initial version of COAST is focused on water quality issues. During early and mid- 2008, initial ideas for COAST were shared and discussed with various CBP partners and other potential user groups. At these meetings, test cases were selected to help improve understanding of the types of information and analytical functionality that would be most useful for specific partners’ needs. These discussions added considerable knowledge about the nature of decisionmaking for Federal, State, local and nongovernmental partners. Version 1.0 of COAST, released in early winter of 2008, will be further reviewed to determine improvements needed to address implementation and assessment of water quality practices. Future versions of COAST may address other aspects of ecosystem restoration, including restoration of habitat and living resources and maintaining watershed health.

  9. Improving Naive Bayes with Online Feature Selection for Quick Adaptation to Evolving Feature Usefulness

    SciTech Connect

    Pon, R K; Cardenas, A F; Buttler, D J

    2007-09-19

    The definition of what makes an article interesting varies from user to user and continually evolves even for a single user. As a result, for news recommendation systems, useless document features can not be determined a priori and all features are usually considered for interestingness classification. Consequently, the presence of currently useless features degrades classification performance [1], particularly over the initial set of news articles being classified. The initial set of document is critical for a user when considering which particular news recommendation system to adopt. To address these problems, we introduce an improved version of the naive Bayes classifier with online feature selection. We use correlation to determine the utility of each feature and take advantage of the conditional independence assumption used by naive Bayes for online feature selection and classification. The augmented naive Bayes classifier performs 28% better than the traditional naive Bayes classifier in recommending news articles from the Yahoo! RSS feeds.

  10. Live deaths online: internet suicide and lethality.

    PubMed

    Klein, Carolina A

    2012-01-01

    The Internet provides an infinite platform for the portrayal of lethal events. Beyond mere display, however, it dispenses information, allows for participation and sharing of content, and constitutes a virtual interactive forum. The Internet may ultimately shape society's approach to perceiving and dealing with death. Thus, psychiatrists may wish to be aware of these matters so that they may be considered in assessments and clinical care. In this article, the author attempts to identify key online locations where lethality is portrayed and how it may affect the individual patient and practitioner and the population at large.

  14. Massively Multiplayer Online Games as Living Laboratories: Opportunities and Pitfalls

    NASA Astrophysics Data System (ADS)

    Ducheneaut, Nicolas

    The digital nature of online games makes them particularly amenable to large-scale, automated data collection and analysis; so researchers have begun to use them as living laboratories to test or refine the existing theories of human behavior. On the basis of several years of intensive data collection in several massively multiplayer online games, this chapter addresses three problems concerning validity and generalizability that must be taken into account. First, each game has a set of laws that steer player behavior, thereby introducing confounding factors that have to be taken into account by the researcher. Second, games attract skewed samples of players, and players may adopt transformed personalities inside the game world, which puts into question the validity of extending findings from observations in the digital realm into the physical one. Third, the lack of a clear boundary defining the "game space," illustrated by the many websites and forums for popular games, raises the question of whether online games themselves capture the totality of the user's experience. The problematic mapping between "real-world" behaviors and those in online games presents research opportunities as well as pitfalls that need to be avoided.

  17. Relationships between the stable isotopic signatures of living and fossil foraminifera in Monterey Bay, California

    Martin, Jonathan B.; Day, Shelley A.; Rathburn, Anthony E.; Perez, M. Elena; Mahn, Chris; Gieskes, Joris

    2004-04-01

    Fossil foraminifera are critical to paleoceanographic reconstructions including estimates of past episodes of methane venting. These reconstructions rely on benthic foraminifera incorporating and retaining unaltered the ambient isotopic compositions of pore fluids and bottom waters. Comparisons are made here of isotopic compositions of abundant live and fossil foraminifera (Uvigerina peregrina, Epistominella pacifica, Bulimina mexicana, and Globobulimina pacifica) collected in Monterey Bay, CA from two cold seeps (Clam Flats and Extrovert Cliffs) and from sediments ˜5 m outside of the Clam Flats seep. Clam Flats has steep δ13CDIC gradients (to <-45‰), but DIC at Extrovert Cliffs is less enriched in 12C (to approximately -22‰). Oxygen isotope values of fossil foraminifera at Clam Flats are ˜1.5‰ enriched in 18O over the living foraminifera, as well as those of both live and fossil foraminifera at Extrovert Cliffs, suggesting they may have lived during the last glacial maximum. Statistical comparisons (Student's t and Kolmogorov-Smirnov tests) of δ13C and δ18O values indicate that live and fossil foraminifera come from different populations at both Clam Flats and Extrovert Cliffs. At Clam Flats, the difference appears to result from alteration enriching some fossil foraminifera in 12C over live foraminifera. At Extrovert Cliffs, the fossil foraminifera are enriched in 13C over the live foraminifera, suggesting they lived prior to the onset of venting and thus that venting began recently. The short time of venting at Extrovert Cliffs may be responsible for the less alteration there compared with Clam Flats. These results indicate that preservation of foraminifera is likely to be poor within long-lived cold seeps, but that foraminifera living in the surrounding sediment may incorporate and preserve broad basin-wide changes in isotopic compositions of the ambient water.

  20. A Novel Artificial Bee Colony Approach of Live Virtual Machine Migration Policy Using Bayes Theorem

    PubMed Central

    Xu, Gaochao; Hu, Liang; Fu, Xiaodong

    2013-01-01

    Green cloud data center has become a research hotspot of virtualized cloud computing architecture. Since live virtual machine (VM) migration technology is widely used and studied in cloud computing, we have focused on the VM placement selection of live migration for power saving. We present a novel heuristic approach which is called PS-ABC. Its algorithm includes two parts. One is that it combines the artificial bee colony (ABC) idea with the uniform random initialization idea, the binary search idea, and Boltzmann selection policy to achieve an improved ABC-based approach with better global exploration's ability and local exploitation's ability. The other one is that it uses the Bayes theorem to further optimize the improved ABC-based process to faster get the final optimal solution. As a result, the whole approach achieves a longer-term efficient optimization for power saving. The experimental results demonstrate that PS-ABC evidently reduces the total incremental power consumption and better protects the performance of VM running and migrating compared with the existing research. It makes the result of live VM migration more high-effective and meaningful. PMID:24385877

    Handler, Lara

    2011-01-01

    The increase in distance education students and the changing preferences for online instruction led the Health Sciences Library to seek creative approaches to traditional classroom instruction. Library instructors compared two different class formats: online-only classes and in-person classes with online sections. The second format, called "co-streaming," provided instruction in traditional classroom and virtual environments at the same time. A postclass survey was used to gather users' evaluations of the instruction and the format via which it was offered. This paper examines the user response to, and satisfaction with, the co-streaming classes.

    2016-03-01

    Background and aims Online gambling appears to have special features, such as anonymity, speed of play and permanent availability, which may contribute to the facilitation and increase in gambling practice, potentially leading to problem gambling. The aims of this study were to assess sociodemographic characteristics, gambling practice and impulsive sensation seeking among a population of regular poker players with different levels of gambling intensity and to compare online and live players. Methods 245 regular poker players (180 online players and 65 live players) completed online self-report scales assessing sociodemographic data, pathological gambling (SOGS), gambling practice (poker questionnaire) and impulsive sensation seeking (ImpSS). We used SOGS scores to rank players according to the intensity of their gambling practice (non-pathological gamblers, problem gamblers and pathological gamblers). Results All poker players displayed a particular sociodemographic profile: they were more likely to be young men, executives or students, mostly single and working full-time. Online players played significantly more often whereas live players reported significantly longer gambling sessions. Sensation seeking was high across all groups, whereas impulsivity significantly distinguished players according to the intensity of gambling. Discussion Our results show the specific profile of poker players. Both impulsivity and sensation seeking seem to be involved in pathological gambling, but playing different roles. Sensation seeking may determine interest in poker whereas impulsivity may be involved in pathological gambling development and maintenance. Conclusions This study opens up new research perspectives and insights into preventive and treatment actions for pathological poker players.

    2017-06-08

    Point-of-care ultrasound (POCUS) is a novel technique for the assessment of jugular venous pressure. Distance education may allow for efficient dissemination of this technique. We compared online learning to a live course for teaching ultrasonography jugular venous pressure (u-JVP) to determine if these teaching methods yielded different levels of comfort with and use of u-JVP. This was an interventional trial of Canadian emergency physicians who had taken a basic POCUS course. The participants were in one of three Groups: online learning (Group OL), live teaching (Group LT), control (Group C). Group LT participants also took an advanced course prior to the study that included instruction in u-JVP. The participants who took the basic course were randomized to Group OL or Group C. Group OL was subject to the intervention, online learning. Group C only received an article citation regarding u-JVP. Questionnaires were completed before and after the intervention. The primary outcome was physician self-reported use and comfort with the technique of u-JVP after online learning compared to live teaching. Of the 287 advanced course participants, 42 completed the questionnaires (Group LT). Of the 3303 basic course participants, 47 who were assigned to Group OL completed the questionnaires and 47 from Group C completed the questionnaires. Use of u-JVP increased significantly in Group OL (from 15% to 55%) and Group C (from 21% to 47%) with the intervention. The comfort with use did not differ between Group LT and Group OL (p=0.14). The frequency of use remained higher in Group LT than Group OL (p=0.07). Online learning increases the use and comfort with performing u-JVP for emergency physicians with prior POCUS experience. Although the comfort with use of u-JVP was similar in Groups LT and OL, online learning appears to yield levels of use that are less than those of a live course.

    This study under the support of the Kenting National Park Headquarters, conducted an on-line real time monitoring system of the water quality in coral reef ecosystem of the Nanwan Bay, southern Taiwan. The monitoring parameters include temperature, salinity, pH, dissolved oxygen, nutrients (e.g., nitrite, nitrate, ammonium, and phosphate), chlorophyll a, as well as turbidity for the “Coral Reef Environmental Observatory Network” monitoring programs. Based on the reliable data obtained through a good quality assurance/quality control (QA/QC) performance has provided a valuable database. Results provide useful contribution to the literature, documenting contamination, environmental conservation and education by on-line real time monitoring in Taiwan. Furthermore, on-line real time monitoring results have also showed helpful explanation for natural episodic events, e.g., cold water intrusion, in this coral reef ecosystem. The program is not only successfully fitted in the bench top simulation, but also has a successful application in field work. The on-line real time monitoring results with emphasizing on the short time scale, e.g., hours to days, effects on coral reef ecosystem has also been discussed in this study.

  18. Seasonal variability of living benthic foraminifera from the outer continental shelf of the Bay of Biscay

    2008-08-01

    Living benthic foraminiferal faunas of six stations from the continental shelf of the Bay of Biscay have been investigated during three successive seasons (spring, summer and autumn 2002). For the three investigated stations, bottom water oxygen concentration, oxygen penetration into the sediment and sediment organic carbon contents are all relatively similar. Therefore, we think that the density and the composition of the foraminiferal faunas is mainly controlled by the quantity and quality of organic input resulting from a succession of phytoplankton bloom events, occurring from late February to early September. The earliest blooms are positioned at the shelf break, late spring and early summer blooms occur off Brittany, whereas in late summer and early autumn, only coastal blooms appear, often in the vicinity of river outlets. In spring, the benthic foraminiferal faunas of central (B, C and D) and outer (E) continental shelf stations are characterised by strong dominance in the first area and strong presence in the second area of Nonionella iridea. In fact, station E does not serve as a major depocenter for the remains of phytoplankton blooms. If station E is not considered, the densities of this taxon show a clear gradient from the shelf-break, where the species dominates the assemblages, to the coast, where it attains very low densities. We explain this gradient as a response to the presence, in early spring, of an important phytoplankton bloom, mainly composed of coccolithophorids, over the shelf break. This observation is supported by the maximum particles flux values at stations close to the shelf break (18.5 g m - 2 h - 1 ) and lower values in a station closer to the coast (6.8 g m - 2 h - 1 ). In summer, the faunal density is maximum at station A, relatively close to more varied phytoplancton blooms that occur off Brittany until early June. We suggest that the dominant species, Nonion fabum, Cassidulina carinata and Bolivina ex. gr. dilatata respond to

    The population of individuals living with dementia and their caregivers and the need to provide caregiver training will increase in the next several decades. In-person caregiver educational programs are delimited by logistical and resource boundaries that could be overcome with online programs. The purpose of this qualitative descriptive study was to explore the acceptability and ways to improve the content and delivery of an online 7-week psychoeducational pilot program-Tele-Savvy. Thirty-six caregivers who completed the pilot were interviewed about their experience with Tele-Savvy and their suggestions for its improvement. Conventional content analysis allowed for the identification of three themes: barriers and facilitators to establishing rapport with participants and instructors, content enrichment and diversification, and structural refinement. These lessons learned directly from the caregivers provide evidence to guide the refinement of analogous online interventions and highlight the need for their wider availability.

  20. Writing Indigenous women's lives in the Bay of Bengal: cultures of empire in the Andaman Islands, 1789-1906.

    PubMed

    Anderson, Clare

    2011-01-01

    This article explores the lives of two Andamanese women, both of whom the British called “Tospy.” The first part of the article takes an indigenous and gendered perspective on early British colonization of the Andamans in the 1860s, and through the experiences of a woman called Topsy stresses the sexual violence that underpinned colonial settlement as well as the British reliance on women as cultural interlocutors. Second, the article discusses colonial naming practices, and the employment of Andamanese women and men as nursemaids and household servants during the 1890s–1910s. Using an extraordinary murder case in which a woman known as Topsy-ayah was a central witness, it argues that both reveal something of the enduring associations and legacies of slavery, as well as the cultural influence of the Atlantic in the Bay of Bengal. In sum, these women's lives present a kaleidoscope view of colonization, gender, networks of Empire, labor, and domesticity in the Bay of Bengal.

  1. Diversity, distribution, and morphological deformities among living Foraminifera in hypersaline Salwa Bay, Saudi Arabia

    The Arabian Gulf is considered a naturally stressed environment due to extremes of salinity and summer temperatures. Anthropogenic influences such as rapid urbanisation projects, maritime transport, and large numbers of desalination plants and oil-related activities compounds the problem. Foraminifera are known to be resilient under such stressful conditions. The purpose of our study is to document the foraminiferal diversity and abundance in the hypersaline Salwa Bay area, near the Saudi Arabian-Qatar Border. We expect the foraminiferal fauna in Salwa Bay to be adapted to extremes in salinity, and we wish to document any species that might be endemic or uniquely adapted to the area. Shannon-Wiener index, relative abundance, species richness, and the percentage of morphological deformities were determined for samples collected from the bay. Salwa Bay is the most saline extension of the Arabian Gulf with high salinity, water temperature and evaporation rate, which is attributed to slow flushing rates, coral reef barriers and higher residency time of the water. Environmental parameters measured at the time of collection were depth (10-110 cm), salinity (52.6-53.0) total dissolved solids (48.8-49.4 g/l), and temperature (27-27.6°C). The foraminiferal assemblages in Salwa Bay are dominated by porcelaneous foraminifera, which include Peneroplis pertusus, Peneroplis planatus, Coscinospira hemprichii and Coscinospira acicularis. The most common species across the sampled transect is Peneroplis pertusus. Hyaline species were also found, but agglutinated foraminifera are absent. Diversity in Salwa Bay is lower compared with localities that have "normal" salinity, and many of the foraminifera display conspicuous morphological deformities. Approximately 55% of the assemblage exhibits mild to severe deformities such as fusion of two adults or double tests, protuberance on the spiral side, abnormal arrangement of the chambers, abnormal shape of the proloculus and modification

    Social media and online environments are becoming increasingly popular and integral to modern lives. The online presentation of suicidal behaviors is an example of the importance of communication technologies, and the need for professionals to respond to a changing world. These types of behaviors, however, have rarely been scientifically analyzed. This study aimed to examine the behaviors of both suicide broadcasters and their audience, with attention on prevention/crisis opportunities. Multiple case studies were employed to explore live-broadcast suicide by Chinese emerging adults (aged 18-25 years). Six cases were selected (four males, two females; aged 19-24, M = 21.60, SD = 2.25), retrieved from 190 public documents (case range = 5 to 32; M = 11.50, SD = 10.37). A qualitative study based on grounded theory was adopted. Information on case background, stages, participants and their behaviors were collected. (1) Five stages of blogcast suicide incidents were revealed, including: Signaling, Initial reactions, Live blogcast of suicide attempts, Crisis responses, and Final outcomes. (2) Common behavioral trends (e.g., comforting, verbal abuse) were identified from the blogcast participants (e.g., active audience, peers, parents and police). (3) Suicide blogcasters exhibited tendencies to communicated signs of pain and cries for help. This multi-case study found live presentations of suicidal behaviors offered unique opportunities to respond to suicidal crises, and also to learn more about the relationships between suicidal people and potential help sources. Findings showed many audience members wanted to be helpful but lacked appropriate skills or knowledge. Others engaged in suicide cyberbullying. The social media is an environment in the making. This study revealed that increasing knowledge and skills for crisis response and suicide prevention is needed. Such efforts could lead to empowered netizens and a more hospitable online world.

    Ionizing radiation poses a threat to genome integrity by introducing DNA damages, particularly DNA double-strand breaks (DSB) in cells. Understanding how cells react to DSB and maintain genome integrity is of major importance, since increasing evidences indicate the links of DSB with genome instability and cancer predispositions. However, tracking the dynamics of DNA damages and repair response to ionizing radiation in individual cell is difficult. Here we describe the development of an on-line irradiation and in situ live cell imaging system based on isotopic sources at Institute of Heavy Ion Physics, Peking University. The system was designed to irradiate cells and in situ observe the cellular responses to ionizing radiation in real time. On-line irradiation was achieved by mounting a metal framework that hold an isotopic γ source above the cell culture dish for γ irradiation; or by integrating an isotopic α source to an objective lens under the specialized cell culture dish for α irradiation. Live cell imaging was performed on a confocal microscope with an environmental chamber installed on the microscope stage. Culture conditions in the environment chamber such as CO2, O2 concentration as well as temperature are adjustable, which further extends the capacity of the system and allows more flexible experimental design. We demonstrate the use of this system by tracking the DSB foci formation and disappearance in individual cells after exposure to irradiation. On-line irradiation together with in situ live cell imaging in adjustable culture conditions, the system overall provides a powerful tool for investigation of cellular and subcellular response to ionizing radiation under different physiological conditions such as hyperthermia or hypoxia.

  4. Online quantitative monitoring of live cell engineered cartilage growth using diffuse fiber-optic Raman spectroscopy.

    Tissue engineering (TE) has the potential to improve the outcome for patients with osteoarthritis (OA). The successful clinical translation of this technique as part of a therapy requires the ability to measure extracellular matrix (ECM) production of engineered tissues in vitro, in order to ensure quality control and improve the likelihood of tissue survival upon implantation. Conventional techniques for assessing the ECM content of engineered cartilage, such as biochemical assays and histological staining are inherently destructive. Raman spectroscopy, on the other hand, represents a non-invasive technique for in situ biochemical characterization. Here, we outline current roadblocks in translational Raman spectroscopy in TE and introduce a comprehensive workflow designed to non-destructively monitor and quantify ECM biomolecules in large (>3 mm), live cell TE constructs online. Diffuse near-infrared fiber-optic Raman spectra were measured from live cell cartilaginous TE constructs over a 56-day culturing period. We developed a multivariate curve resolution model that enabled quantitative biochemical analysis of the TE constructs. Raman spectroscopy was able to non-invasively quantify the ECM components and showed an excellent correlation with biochemical assays for measurement of collagen (R(2) = 0.84) and glycosaminoglycans (GAGs) (R(2) = 0.86). We further demonstrated the robustness of this technique for online prospective analysis of live cell TE constructs. The fiber-optic Raman spectroscopy strategy developed in this work offers the ability to non-destructively monitor construct growth online and can be adapted to a broad range of TE applications in regenerative medicine toward controlled clinical translation.

    2014-04-01

    The purpose of CanTeen's E-Mental Health Service for Young People Living With Cancer (YPLWC) is to meet the unique psychosocial needs of young people (12-24 years) in Australia impacted by cancer (either as a patient or family member of someone with cancer). This online platform will provide the primary site where all YPLWC can find information, connect with others going through a similar experience, express their feelings, utilise tools for support and access professional psychosocial support services that will meet their individual needs. The overall outcome of the service will be to ensure that the YPLWC visiting the site experience optimal psychological wellbeing. Ultimately, the service's value will be in improving the lives of young people who engage with it and the follow-on effect that this will have on their families and communities in the long-term.

    Determine whether lectures by national experts and a publicly available online program with similar educational objectives can improve knowledge, attitudes, and beliefs (KAB) important to chronic pain management. A pretest-posttest randomized design with two active educational interventions in two different physician groups and a third physician group that received live education on a different topic to control for outside influences, including retesting effects, on our evaluation. A total of 136 community-based primary care physicians met eligibility criteria. All physicians attended the educational program to which they were assigned. Ninety-five physicians (70%) provided complete data for evaluation. Physician responses to a standardized 50-item pain management KAB survey before, immediately after, and 3 months following the interventions. The study groups and the 41 physicians not providing outcomes information were similar with respect to age, sex, race, percent engaged in primary care, and number of patients seen per week. Physician survey scores improved immediately following both pain education programs (live: 138.0-->150.6, P < 0.001; online: 143.6-->150.4, P = 0.007), but did not change appreciably in the control group (139.2-->142.5, P > 0.05). Findings persisted at 3 months. Satisfaction measures were high (4.00-4.72 on 1-5 scale) and not significantly different (P = 0.072-0.893) between groups. When used under similar conditions, national speakers and a publicly available online CME program were associated with improved pain management KAB in physicians. The benefits lasted for 3 months. These findings support the continued use of these pain education strategies.

    It is unknown if online social networking technologies are already highly integrated among some people living with HIV (PLWH) or have yet to be adopted. To fill this gap in understanding, 312 PLWH (84% male, 69% white) residing in the US completed on online survey in 2009 of their patterns of social networking and mobile phone use. Twenty-two persons also participated in one of two online focus groups. Results showed that 76% of participants with lower adherence to HIV medication used social networking websites/features at least once a week. Their ideal online social networking health websites included one that facilitated socializing with others (45% of participants) and relevant informational content (22%), although privacy was a barrier to use (26%). Texting (81%), and to a lesser extent mobile web-access (51%), was widely used among participants. Results support the potential reach of online social networking and text messaging intervention approaches. PMID:22350832

  10. Crossing over: The lived experiences of clinical laboratory science education teachers as they transition from traditional to online instruction

    NASA Astrophysics Data System (ADS)

    Veldkamp, Ruth B.

    A phenomenological study was undertaken to understand and describe the nature and meaning of the live experiences of faculty transition from traditional to teaching online clinical laboratory science courses. In order to gain insight into the lived experiences of faculty, in-depth interviews were conducted with 10 faculty members. The task of the researcher was to allow the participants to speak for themselves, and reveal the meaning of the experiences, rather than to discover causal connections or patterns of correlation. The key criterion in choosing purposeful sampling procedure was to obtain the deepest understanding possible of the lived experiences of faculty transitioning to online teaching, which were likely to be a rich source of the data of interest. Analyses of the interview text were based on three essential considerations. The three essential considerations were (a) the traditional role of the faculty, (b) factors affecting the changing role of the faculty, and (c) the effects of web-based technology on teaching role.

    2016-09-01

    Internet sales of human remains occur despite the existence of laws prohibiting such action in most jurisdictions. The most popular public platform for online sales, eBay, allows users to postskeletal material for sale, largely anonymously and without much fear of legal repercussions. This survey of skeletal sales was conducted 10 years after the first article published about online human remains sales. A review of current laws reveals that, while many states have laws that restrict any sale of human remains, those laws have questionable deterrent effect. Assessing the skeletal material posted for sale provides law enforcement agencies with a necessary starting point to curtail the sale of human remains through enforcement of existing laws. Ultimately, the goal is to stem the commodification of such items and to recover skeletal material, especially that which may be of archaeological or forensic significance, and provide the proper final disposition for such material.

    The decapod taxocoenosis living in shallow muddy bottoms with the green algae Caulerpa prolifera was studied monthly between February 1994 and January 1996 in the Inner Bay of Cádiz (SW Spain). More than 32,000 specimens belonging to 35 species were collected. Six species were dominant (representing the 85.8% of the total number of specimens), but the structure of the taxocoenosis was regulated by the Hippolyte species, Sicyonia carinata, Palaemon adspersus and Liocarcinus arcuatus. There was no significant qualitative difference between years. There was no clear change in the dominance of groups of species during the year, as happened in the outer Bay. This is probably due to the sheltered character of the area and the more stable and dense vegetal cover, but some seasonal differences were found. The benthic characteristics of the Inner Bay of Cádiz, such as shallow soft bottoms of fine and muddy sediments and the presence of macrophytes (seagrasses and seaweeds) might be key factors influencing the composition and structure of the general and seasonal decapod assemblage. In spite of human impacts on the bay (e.g. aquaculture activities, sewage), the values of the diversity, equitability and richness indexes appeared stable over time (higher than those found in outer adjacent areas) and no significant differences between years were found.

    2017-08-10

    The aim of this study was to explore the work-life narratives of nurses through a thematic analysis of the nursing accounts they post in their publicly accessible, anonymous blogs. Many nurses participate on social media. Blogs have been advocated as a self-reflective tool in nursing practice, yet as far as the authors are aware, no previous studies have explored nurses' individual blogs for their potential to reveal nurses' perceptions of nursing work. The research design was qualitative description. Between May-August 2015, Internet search engines were used to discover lists of nursing blogs recommended by organizations representing nurses' interests. Recommended blogs were purposively sampled. Four anonymous blogs written by nurses from different nursing specialties met the sampling criteria. All 520 of their entries from 2014 were read and copied into NVivo 10, where an inductive coding process was followed. Three major themes arose in these nurses' online discussions of their work lives: they truly care about and value their nursing work, but they are feeling stressed and burnt out and they are using their anonymous blogs to share factors that frustrate them in their nursing work. Three main areas of frustration were revealed: teamwork problems, challenging patients and families, and management issues. Anonymous nursing blogs offer valuable, longitudinal insights into nurses' perceptions of their work lives. Nursing blogs should be further explored for ongoing insights into nurses' experiences of nursing work, as well as nurses' recommendations for addressing issues causing them to feel frustrated in their work environments. © 2017 John Wiley & Sons Ltd.

    Background Increasing numbers of people are living with, and beyond, cancer. They are at risk of long-term morbidity and premature mortality due to the consequences of their disease and its treatment. Primary care can contribute to providing ongoing care. Aim To determine the current practice and views of GPs in England regarding cancer survivorship care. Design and setting Online survey of a sample of 500 GPs, stratified by NHS region in England. Method The survey included questions adapted from prior surveys assessing physician knowledge and attitudes regarding care of patients with cancer. Results In total, 500 GPs responded; approximately half reported often providing care to people living beyond cancer for treatment-related side effects (51%), psychological symptoms (65%), and lifestyle advice (55%). Only 29% felt very confident managing treatment-related side effects compared with 46% and 65% for psychological symptoms and lifestyle advice respectively. Half reported usually receiving cancer treatment summaries and survivorship care plans but most of the sample felt these would improve their ability to provide care (76%). Only 53% were convinced of the usefulness of cancer care reviews. Although most felt that primary and specialist care should share responsibility for managing bone (81%) and cardiovascular (77%) health consequences, fewer than half reported often taking previous history of cancer or cancer treatment into consideration when assessing bone health; only one-fifth did this in relation to cardiovascular health. Most responders were interested in receiving education to improve their knowledge and expertise. Conclusion GPs have a potentially important role to play in caring for people following cancer treatment. This study has highlighted areas where further support and education are needed to enable GPs to optimise their role in cancer survivorship care. PMID:26500324

    Background Polycystic Ovary Syndrome is a common, chronic condition which affects women living with the condition both physically and psychologically. Social support may be beneficial to sufferers in coping with chronic conditions and the Internet is becoming a common place for accessing social support and information. The aim of this study was to consider the experiences of women living with Polycystic Ovary Syndrome who access and participate in an online support group discussion forum dedicated to issues surrounding this condition. Methods Fifty participants responded to a series of open-ended questions via an online survey. Results Thematic analysis revealed a number of empowering and disempowering experiences associated with online support group participation. The empowering processes reported by members of the group included: Connecting with others who understand; Access to information and advice; Interaction with healthcare professionals; Treatment-related decision making; Improved adjustment and management. In terms disempowering processes, only two were described by group participants: Reading about the negative experiences of others and Feeling like an outsider. Conclusions For women living with Polycystic Ovary Syndrome, participation within an online support group may help to empower them in a range of important ways however, there may be some disempowering consequences.

    2005-04-01

    To compare the effectiveness of traditional and online teaching methods for educating anesthesiology residents in the principles and practice of difficult airway management. Prospective, randomized, controlled trial. University hospital. Two randomly selected groups, each containing 28 physicians enrolled from among residents in Anesthesiology and Intensive Care Medicine in Italy. Residents in Group 1 took a traditional 5-h course on the principles and practice of airway management, which included lectures, slide projection, and dummy demonstrations. The same material was presented to Group 2 in an exclusively online format, which could be individually accessed for a period of 36 h. In the online course, student-instructor interaction was provided through threaded discussion forums during three 30-min real-time question-and-answer sessions. Differences in baseline and post-course scores on written tests and practical skills tests were measured. Knowledge gains in Group 2 were slightly, but not significantly, greater compared with Group 1 both in written (P=0.228) and practical skills (P=0.376) tests. Semi-quantitative ratings of learner satisfaction were significantly higher in the online group (P=0.014). Almost all online students (93%) were logged in for at least 45 of the 90 min of real-time question-and-answer sessions. The four instructors spent an average of 144+/-10 min preparing answers and interacting with online students. Online teaching formats may be a valid alternative for teaching residents the principles and practice of difficult airway management. Interaction with instructors seems to be an important element, but it may require substantial time commitments by instructors.

    Bond, Carol S; Ahmed, Osman Hassan

    2016-11-10

    Peer-to-peer health care is increasing, especially amongst people living with a long-term condition. How information is shared is, however, sometimes of concern to health care professionals. This study explored what information is being shared on health-related discussion boards and identified the approaches people used to signpost their peers to information. This study was conducted using a qualitative content analysis methodology to explore information shared on discussion boards for people living with diabetes. Whilst there is debate about the best ethical lens to view research carried out on data posted on online discussion boards, the researchers chose to adopt the stance of treating this type of information as "personal health text", a specific type of research data in its own right. Qualitative content analysis and basic descriptive statistics were used to analyse the selected posts. Two major themes were identified: 'Information Sharing from Experience' and 'Signposting Other Sources of Information'.Conclusions People were actively engaging in information sharing in online discussion forums, mainly through direct signposting. The quality of the information shared was important, with reasons for recommendations being given. Much of the information sharing was based on experience, which also brought in information from external sources such as health care professionals and other acknowledged experts in the field.With the rise in peer-to-peer support networks, the nature of health knowledge and expertise needs to be redefined. People online are combining external information with their own personal experiences and sharing that for others to take and develop as they wish.

Qualitative data were analyzed in Dedoose software using grounded theory methodology. Ten primary motivating factors for recovering from methamphetamine abuse were identified and mapped onto four constructs from the Health Belief Model: (1) perceived susceptibility (learning from others and learning from self); (2) perceived severity (fear of death and declining health); (3) perceived benefits (reconnecting with family, reconnecting with society, and recovering self-esteem); and (4) cues to action (hitting rock bottom, finding God, and becoming pregnant). By using data from an online support group and categorizing emerging themes within a theoretical framework, findings from this study provide a comprehensive understanding of factors involved in recovery from methamphetamine abuse and offer further insights in developing theoretically informed interventions for methamphetamine users. This study suggests the utility of online platforms for obtaining anonymous but unique experiences about drug abuse and recovery. Findings may benefit healthcare professionals, counselors, and researchers by helping to develop theoretically informed interventions for methamphetamine abuse.

  9. Using copper ions to amplify ROS-mediated fluorescence for continuous online monitoring of extracellular glucose in living rat brain.

    PubMed

    2015-02-15

    In this study we developed a facile and sensitive method for continuous monitoring of extracellular glucose concentration in living rat brain through microdialysis (MD) sampling in conjunction with (i) online sample derivatization using glucose oxidase to generate H2O2, which converted a reactive oxygen species-responsive fluorescent dye, 2',7'-dichlorodihydrofluorescein (DCFH), into fluorescent species, and (ii) a novel non-immobilized enzyme-based fluorescence assay strategy, featuring copper ion (Cu(2+))-facilitated amplification of the fluorescence intensity. After evaluating the experimental conditions for glucose oxidation and fluorescence generation, the introduction of Cu(2+) ions to this system resulted in an additional 51-fold amplification of the net fluorescence intensity. By sequentially loading brain microdialysate into the dual sample collection loops, the sampling frequency was 7.5h(-1). Based on a 40-μL sample volume, the system's detection limit reached as low as 0.18 mM, sufficiently accurate to determine the extracellular glucose concentrations in living rat brains. To demonstrate the proposed system's practical performance and applicability, we conducted (i) spike analyses of biomolecule-rich fetal bovine serum sample, confirming that the analytical reliability was similar to that of a commercial glucose kit, and (ii) in vivo dynamic monitoring of the extracellular glucose concentrations in living rat brains after inducing neural depolarization by perfusing a high-K(+) medium from the MD probe.

    Haney, Jolynn L; Cullen, Jennifer A

    2017-01-01

    The experience of being an adult female with an autism spectrum disorder (ASD) has been understudied in social work literature. The purpose of this study was to develop an understanding of females with ASD, from their perspective, by examining content from an online autism community Web site. Using a phenomenological approach, data analysis on content obtained from the forum revealed several themes about the women's experiences concerning the diagnostic process, managing and understanding symptoms, and the impact of ASD on their personal and work relationships. Implications for social work practice, including creating more effective services for females with ASD, are discussed.

  11. Exploring the social lives of image and performance enhancing drugs: An online ethnography of the Zyzz fandom of recreational bodybuilders.

    PubMed

    Underwood, Mair

    2017-01-01

    As a result of the mainstreaming of bodybuilding, the majority of image and performance enhancing drug (IPED) users are now not athletes or competitive bodybuilders, but recreational bodybuilders. Previous approaches provide little insight into how the shift from competitive to recreational contexts impacts the use of IPEDs. In this study an online ethnographic approach is used to explore the social lives of IPEDs in a recreational context. The study focusses on the Zyzz fandom, an international online community of thousands of recreational bodybuilders who idolise the alleged IPED user Zyzz. Zyzz fans see IPED prohibition as failing, as causing harm to users, and as sexist. Their IPED use is informed by not only instrumental benefits, but social benefits such as altering gendered power relations. IPEDs have been normalised in this community, and new patterns of use are emerging. IPEDS have moved through different hands, contexts and uses, and in so doing the values, norms and meanings attached to IPEDs have changed. The results suggest that intervention efforts may be best directed towards harm minimisation, and in particular towards bridging the divides between the medical and bodybuilding communities.

  12. Chesapeake Bay Program Water Quality Database

    EPA Pesticide Factsheets

    The Chesapeake Information Management System (CIMS), designed in 1996, is an integrated, accessible information management system for the Chesapeake Bay Region. CIMS is an organized, distributed library of information and software tools designed to increase basin-wide public access to Chesapeake Bay information. The information delivered by CIMS includes technical and public information, educational material, environmental indicators, policy documents, and scientific data. Through the use of relational databases, web-based programming, and web-based GIS a large number of Internet resources have been established. These resources include multiple distributed on-line databases, on-demand graphing and mapping of environmental data, and geographic searching tools for environmental information. Baseline monitoring data, summarized data and environmental indicators that document ecosystem status and trends, confirm linkages between water quality, habitat quality and abundance, and the distribution and integrity of biological populations are also available. One of the major features of the CIMS network is the Chesapeake Bay Program's Data Hub, providing users access to a suite of long- term water quality and living resources databases. Chesapeake Bay mainstem and tidal tributary water quality, benthic macroinvertebrates, toxics, plankton, and fluorescence data can be obtained for a network of over 800 monitoring stations.

    In 2006, a survey from the American Society of Transplant Surgeons disclosed significant and sometimes fatal hemorrhagic events in live donor nephrectomies (LDN) related to failure of clips, leading to the contraindication of the Weck® Hem-o-lok® clip for control of the renal artery during LDN. A survey regarding vascular control techniques, their perceived safety ratings and their failures was sent to 645 European Society for Organ Transplantation members who profiled their profession as "surgeon" and selected "kidney" as organ type. Two hundred forty-three (41%) members responded, of whom 171 (63.3%) independently perform LDN. Their responses were analyzed. For arterial and venous vascular control, the GIA™ and TA™stapler are used most frequently, and were rated the safest. Of the 121 reported hemorrhagic events, slippage and dislodgement of clips occurred at least 58 times, while stapler malfunction occurred at least 40 times. One donor death from hemorrhage related to clip dysfunction was reported. Hemorrhagic complications of LDN with fatal and non-fatal outcomes still occur. Strikingly, many surgeons do not use the vascular closing technique that they consider most safe. Failure of non-transfixion techniques is associated with greater risks for the donor. Control of major vessels in LDN must employ transfixion techniques for optimal donor safety.

  16. Live monitoring and quasi-online event reconstruction for KM3NeT

    2016-04-01

    KM3NeT is a new generation neutrino telescope in the abyss of the Mediterranean Sea. It will instrument a volume of several cubic kilometres of sea water in its final configuration. Currently, the project is in its first phase with the aim of constructing and installing 31 detection units up to 700 m in height, each equipped with 18 digital optical modules. The optical modules are equipped with 31 3-inch photomultipliers to detect the Cherenkov light of charged secondary particles produced in high-energy neutrino interactions. This contribution describes a live detector monitoring system, which enables real-time parameter control and a reconstruction of events soon after the data acquisition. It also allows a rapid response to or provision of external alarms of multi-messenger campaigns. The data acquisition system of KM3NeT provides pre-filtered data in event form, as well as general detector status messages. The events will be processed almost in real-time - with a delay in the range of minutes - using fast reconstruction mechanisms. This allows for high-level monitoring of the detector status using derived distributions, such as time and charge distributions and event rates. The resulting data is displayed on a web page using a dedicated, flexible web service. The same service also displays low-level monitoring data such as trigger rates, PMT hit rates and the general status of the optical modules.

  17. Real-time Visualization of Photochemically Induced Fluorescence of 8-Halogenated Quinolones: Lomefloxacin, Clinafloxacin and Bay3118 in Live Human HaCaT Keratinocytes†

    Halogenoquinolones are potent and widely used antimicrobials blocking microbial DNA synthesis. However, they induce adverse photoresponses through the absorption of UV light, including phototoxicity and photocarcinogenicity. The phototoxic responses may be the result of photosensitization of singlet oxygen, production of free radicals and/or other reactive species resulting from photodehalogenation. Here, we report the use of laser scanning confocal microscopy to detect and to follow the fluorescence changes of one monohalogenated and three di-halogenated quinolones in live human epidermal keratinocyte cells during in situ irradiation by confocal laser in real time. Fluorescence image analysis and co-staining with the LysoTracker probe showed that lysosomes are a preferential site of drug localization and phototransformations. As the lysosomal environment is relatively acidic, we also determined how low pH may affect the dehalogenation and concomitant fluorescence. With continued UV irradiation, fluorescence increased in the photoproducts from BAY y3118 and clinafloxacin, whereas it decreased for lomefloxacin and moxifloxacin. Our images not only help to localize these phototoxic agents in the cell, but also provide means for dynamic monitoring of their phototransformations in the cellular environment. PMID:20492567

    To elucidate the relationship between particle-attached (PA, ≥ 5.0 μm) and free-living (FL, 0.2-5.0 μm) bacterial communities, samplings were collected seasonally from November 2011 to August 2012 in Meiliang Bay, Lake Taihu, China. We used 454 pyrosequencing of 16S rRNA genes to study bacterial diversity and structure of PA and FL communities. The analysis rendered 37,985 highly qualified reads, subsequently assigned to 1755 operational taxonomic units (97% similarity) for the 8 samples. Although 27 high-level taxonomic groups were obtained, the 3 dominant phyla (Proteobacteria, Actinobacteria, and Bacteroidetes) comprised about 75.9% and 82.4% of the PA and FL fractions, respectively. Overall, we found no significant differences between community types, as indicated by ANOSIM R statistics (R = 0.063, P > 0.05) and the Parsimony test (P = 0.222). Dynamics of bacterial communities were correlated with changes in concentrations of total suspended solids (TSS) and total phosphorus (TP). In summer, a significant taxonomic overlap in the 2 size fractions was observed when Cyanobacteria, a major contributor of TSS and TP, dominated in the water, highlighting the potential rapid exchange between PA and FL bacterial populations in large shallow eutrophic lakes.

    Two new species of free-living marine nematode from mangrove habitats in Xiamen Bay are identified. Anoplostoma tumidum sp. nov. is characterized by relatively short outer labial setae (0.86-1.00 h. d.), long tail (c 7.2-8.9, c' 8.3-10.5), an instinct swollen distal portion of slender spicule (Sc 94-101 µm), and well developed copulatory bursae without bursal papillae. A. tumidum sp. nov. differs from all valid species of genus Anoplostoma in copulatory apparatus of males with a distinct swollen distal portion of spicule, and a relatively obvious constriction of head. A. paraviviparum sp. nov. is characterized by relatively long outer labial setae (1.11-1.22 h. d.), and tail (c 6.6-8.5, c' 8.6-10.2); elongated spicules with distinct knob-like proximal and pointed distal ends (Sc 46-69 µm); distinct strip-like gubernaculum (length with 11-15µm); well developed copulatory bursae with precloacal papillae and post-cloacal papillae; and a distinct constriction of head. A. paraviviparum sp. nov. is similar to A. viviparum Bastian, 1865, but differs in the reproductive mode of female and the constriction of head.

    Schools are a common setting for adolescents to receive health education, but implementation of these programs with high levels of completeness and fidelity is not self-evident. Programs that are only partially implemented (completeness) or not implemented as instructed (fidelity) are unlikely to be effective. Therefore, it is important to identify which determinants affect completeness and fidelity of program implementation. As part of the launch of Long Live Love+ (LLL+), an online school-based sexuality education program for adolescents aged 15-17, we performed a process evaluation among teachers and students to measure the levels of completeness and fidelity, identify factors influencing teachers' implementation, and to evaluate the students' response. Sixteen Biology teachers from nine secondary schools throughout the Netherlands who implemented LLL+ were interviewed and 60 students participated in 13 focus group discussions. Results showed that teachers' completeness ranged between 22-100% (M = 75%). Fidelity was high, but many teachers added elements. Teachers and students enjoyed LLL+, particularly the diversity in the exercises and its interactive character. The most important factors that influenced implementation were time and organizational constraints, lack of awareness on the impact of completeness and fidelity, and student response. These factors should be taken into account when developing school-based prevention programs. © The Author 2017. Published by Oxford University Press. All rights reserved.

    The Army maintains 19 installations within the Chesapeake Bay watershed. In response to the Bay`s declining water quality and living resources and to the 1983 Chesapeake Bay Agreement which set forth Bay restoration goals and initiatives, the Department of Defense (DoD) became formally involved in the Bay`s restoration effort in 1984 with the signing of the EPA/DoD Chesapeake Bay Initiative--A Joint Resolution on Pollution Abatement in the Chesapeake Bay. This agreement eventually led to the Army`s development of the Chesapeake Bay Initiative (CBI) Program in 1990, which formally organized Army installation efforts in the restoration of the Chesapeake Bay.

    This qualitative systematic review investigated how individuals with chronic illness experience online peer-to-peer support and how their experiences influence daily life with illness. Selected studies were appraised by quality criteria focused upon research questions and study design, participant selection, methods of data collection, and methods of analysis. Four themes were identified: (a) illness-associated identity work, (b) social support and connectivity, (c) experiential knowledge sharing, and (d) collective voice and mobilization. Findings indicate that online peer-to-peer communities provide a supportive space for daily self-care related to chronic illness. Online communities provided a valued space to strengthen social ties and exchange knowledge that supported offline ties and patient-doctor relationships. Individuals used online communities to exchange experiential knowledge about everyday life with illness. This type of knowledge was perceived as extending far beyond medical care. Online communities were also used to mobilize and raise collective awareness about illness-specific concerns.

    A growing number of online pharmacies have been established worldwide. Among them are numerous illegal websites selling medicine without valid medical prescriptions or distributing substandard or counterfeit drugs. Only a limited number of studies have been published on Internet pharmacies with regard to patient safety, professionalism, long-term follow-up, and pharmaceutical legitimacy verification. In this study, we selected, evaluated, and followed 136 Internet pharmacy websites aiming to identify indicators of professional online pharmacy service and online medication safety. An Internet search was performed by simulating the needs of potential customers of online pharmacies. A total of 136 Internet pharmacy websites were assessed and followed for four years. According to the LegitScript database, relevant characteristics such as longevity, time of continuous operation, geographical location, displayed contact information, prescription requirement, medical information exchange, and pharmaceutical legitimacy verification were recorded and evaluated. The number of active Internet pharmacy websites decreased; 23 of 136 (16.9%) online pharmacies ceased operating within 12 months and only 67 monitored websites (49.3%) were accessible at the end of the four-year observation period. However, not all operated continuously, as about one-fifth (31/136) of all observed online pharmacy websites were inaccessible provisionally. Thus, only 56 (41.2%) Internet-based pharmacies were continuously operational. Thirty-one of the 136 online pharmacies (22.8%) had not provided any contact details, while only 59 (43.4%) displayed all necessary contact information on the website. We found that the declared physical location claims did not correspond to the area of domain registration (according to IP address) for most websites.

    Unlike those infected by H5N1, birds infected by the newly discovered H7N9 virus have no observable clinical symptoms. Public health workers in China do not know where the public health threat lies. In this study, we used a distributed focused crawler to analyze online knowledge of the live bird trade in first-wave provinces, namely, Jiangsu, Zhejiang, Anhui, and Shanghai, to track the new H7N9 virus and predict its spread. Of the 18 provinces proposed to be at high risk of infection, 10 reported human infections and one had poultry specimens that tested positive. Five provinces (Xinjiang, Yunnan, Guizhou, Shaanxi, and Tibet) as well as Hong Kong, Macao, and Taiwan were proposed to have no risk of H7N9 virus infection from the live bird trade. These data can help health authorities and the public to respond rapidly to reduce damage related to the spread of the virus.

    2015-10-01

    The advent of the diagnostic radiology core examination and the new ACGME "milestone" evaluation system for radiology residents places new emphasis on topics in MRI and CT safety, and MRI and CT contrast agents. We evaluated whether either lecture-based teaching or online modules would improve baseline resident knowledge in these areas, and assessed which intervention was more effective. Before didactic intervention, 2 cohorts were created from 57 radiology residents, with equal numbers and a matched level of training. The residents were tested on their baseline knowledge of MRI, MRI contrast safety, and CT contrast safety, using a multiple-choice examination. One group attended a live, 1-hour lecture on the preceding topics. The other engaged in 3 short online educational modules. After 6 weeks, the residents were again tested with the same questions to assess for improvement in their understanding. Both the module and lecture cohorts demonstrated a statistically significant increase in questions answered correctly on CT contrast safety (13.1%, P < .001, and 19.1%, P < .001, respectively), and on MRI and MRI contrast safety (12.9%, P < .001, and 14.4%, P < .001). The preintervention and postintervention scores, and degree of improvement postintervention, were similar for the module versus lecture groups, without a statistically significant difference (P = .70). Resident confidence improved in both groups, for both modalities. Focused didactic intervention improves resident knowledge of MRI and CT safety, and MRI and CT contrast agents. Live lectures and online modules can be equally effective, allowing residency programs flexibility. Copyright © 2015 American College of Radiology. Published by Elsevier Inc. All rights reserved.

    Drug use among gay and bisexual men (GBM) is higher than most populations. The use of crystal methamphetamine, erectile dysfunction medication (EDM), and amyl nitrite have been associated with sexual risk behaviour and HIV infection among gay and bisexual men (GBM). This paper describes an online prospective observational study of licit and illicit drug use among GBM and explores baseline prevalence of drug use in this sample. Capturing these data poses challenges as participants are required to disclose potentially illegal behaviours in a geographically dispersed country. To address this issue, an entirely online and study specific methodology was chosen. Men living in Australia, aged 16.5 years of age or older, who identified as homosexual or bisexual or had sex with at least one man in the preceding 12 months were eligible to enrol. Between September 2014 and July 2015, a total of 2250 participants completed the baseline questionnaire, of whom, 1710 (76.0%) consented to six-monthly follow-up. The majority (65.7%) were recruited through Facebook targeted advertising. At baseline, over half (50.5%) the men reported the use of any illicit drug in the previous six months, and 28.0% had used party drugs. In the six months prior to enrolment, 12.0% had used crystal methamphetamine, 21.8% had used EDM, and 32.1% had used amyl nitrite. Among the 1710 men enrolled into the cohort, 790 men had used none of these drugs. Ease of entry and minimal research burden on participants helped ensure successful recruitment into this online cohort study. Study outcomes will include the initiation and cessation of drug use, associated risk behaviours, and health consequences, over time. Results will provide insights into the role gay community plays in patterns of drug use among GBM. Copyright © 2016 Elsevier B.V. All rights reserved.

    Social support can improve outcomes for people living with HIV (PLWH) and could be provided through online support groups. The Positive Links smartphone app is a multicomponent intervention that allows users to interact in a clinic-affiliated anonymous online support group. We investigated how social support was exchanged in a group of 55 participants over 8 months, using an adaptation of the Social Support Behavior Code. Participant interviews assessed their experiences and perceptions of the app. Of 840 posts analyzed, 115 (14 %) were coded as eliciting social support and 433 (52 %) as providing social support. Messages providing support were predominantly emotional (41 %), followed by network (27 %), esteem (24 %), informational (18 %), and instrumental (2 %) support. Participants perceived connection and support as key benefits of the app. Technical issues and interpersonal barriers limited some participants in fully using the app. Mobile technology offers a useful tool to reach populations with barriers to in-person support and may improve care for PLWH.

    Living with HIV makes considerable demands on a person in terms of self-management, especially as regards adherence to treatment and coping with adverse side-effects. The online HIV Treatment, Virtual Nursing Assistance and Education (Virus de I'immunodéficience Humaine-Traitement Assistance Virtuelle Infirmière et Enseignement; VIH-TAVIE™) intervention was developed to provide persons living with HIV (PLHIV) with personalized follow-up and real-time support in managing their medication intake on a daily basis. An online randomized controlled trial (RCT) will be conducted to evaluate the efficacy of this intervention primarily in optimizing adherence to combination anti-retroviral therapy (ART) among PLHIV. A convenience sample of 232 PLHIV will be split evenly and randomly between an experimental group that will use the web application, and a control group that will be handed a list of websites of interest. Participants must be aged 18 years or older, have been on ART for at least 6 months, and have internet access. The intervention is composed of four interactive computer sessions of 20 to 30 minutes hosted by a virtual nurse who engages the PLHIV in a skills-learning process aimed at improving self-management of medication intake. Adherence constitutes the principal outcome, and is defined as the intake of at least 95% of the prescribed tablets. The following intermediary measures will be assessed: self-efficacy and attitude towards antiretroviral medication, symptom-related discomfort, and emotional support. There will be three measurement times: baseline (T0), after 3 months (T3) and 6 months (T6) of baseline measurement. The principal analyses will focus on comparing the two groups in terms of treatment adherence at the end of follow-up at T6. An intention-to-treat (ITT) analysis will be carried out to evaluate the true value of the intervention in a real context. Carrying out this online RCT poses various challenges in terms of recruitment, ethics, and

    In 2007, the U.S. Southeast experienced one of the worst droughts on record. Since 1970, moderate-to-severe droughts in the Southeast have increased by 12-14% and annual average temperature has risen over 1°C. Several global climate models also project warming across the Southeast and an increased rate of warming through the end of the century. The Southeast has also undergone unprecedented growth, with some counties of Florida and Georgia populations increasing by over 500% in the last several decades, further increasing the demand for water resources during times of drought. Two regional efforts are currently underway to help inform constituents about adaptation to climate variability and change in the Southeast region. The first effort is the National Integrated Drought Information System (NIDIS), led by NOAA. NIDIS serves as an early warning system for drought through the consolidation of physical/hydrological and socioeconomic impact data, engages those affected by drought, integrates observing networks, and delivers decision-support tools to end-users. The second effort is the USGS’ National Climate Change and Wildlife Science Center, which will facilitate linking global and regional climate models to ecological and biological responses at spatial and temporal resolutions that will inform resource management decisions. Both efforts will be operating in the Apalachicola-Chattahoochee-Flint (ACF) River Basin. During the 2007 drought, one of the most publicized impacts was on the oyster fishery in Apalachicola Bay. Reduced regional precipitation along with associated higher demands for water uses in the ACF reduced downstream flow into the Bay, producing harmful effects on the oyster fishery and associated ecosystem. Changes in estuarine salinity resulting from alterations in streamflow can lead to impacts on species abundance and community composition. Drought can also lead to changes in predator-prey interactions, as marine predators typically move into

    2017-02-08

    Exploration of brain extracellular non-protein-bound/diffusible iron species remains a critically important issue in investigations of free radical biology and neurodegenerative diseases. In this study, a facile sample pretreatment scheme, involving poly(vinyl chloride)-metal ion interactions as a selective extraction procedure, was optimized in conjunction with microdialysis (MD) sampling and inductively coupled plasma mass spectrometry (ICP-MS) in cool-plasma mode for in vivo online monitoring of rat brain extracellular Fe(II) and Fe(III) species. Optimization of the system provided detection limits in the range 0.9-6.9 μg Fe L(-1), based on a 12-μL microdialysate, for the tested iron species; relative standard deviations of the signal intensities during 7.8 h of continuous measurement were less than 9.4%-sufficient to determine the basal concentrations of rat brain extracellular Fe(II) and Fe(III) species and to describe their dynamic actions. The method's applicability was verified through (i) spike analyses of offline-collected rat brain microdialysates, (ii) determination of the basal Fe(II) and Fe(III) concentrations of living rat brain extracellular fluids, and (iii) monitoring of the dynamic changes in the Fe(II) and Fe(III) concentrations in response to perfusion of a high-K(+) medium. This proposed sample pretreatment scheme, based on polymer-metal ion interactions and hyphenation to an MD sampling device and an ICP-MS system, appears to have great practicality for the online monitoring of rat brain extracellular diffusible iron species.

    The Galveston Bay estuary is located on the upper Texas Gulf coast (Lester and Gonzalez, 2002). It is composed of four major sub-bays—Galveston, Trinity, East, and West Bays. It is Texas’ largest estuary on the Gulf Coast with a total area of 155,399 hectares (384,000 acres) and 1,885 km (1,171 miles) of shoreline (Burgan and Engle, 2006). The volume of the bay has increased over the past 50 years due to subsidence, dredging, and sea level rise. Outside of ship channels, the maximum depth is only 3.7 m (12 ft), with the average depth ranging from 1.2 m (4 ft) to 2.4 m (8 ft)— even shallower in areas with widespread oyster reefs (Lester and Gonzalez, 2002). The tidal range is less than 0.9 m (3 ft), but water levels and circulation are highly influenced by wind. The estuary was formed in a drowned river delta, and its bayous were once channels of the Brazos and Trinity Rivers. Today, the watersheds surrounding the Trinity and San Jacinto Rivers, along with many other smaller bayous, feed into the bay. The entire Galveston Bay watershed is 85,470 km2 (33,000 miles2 ) large (Figure 1). Galveston Island, a 5,000 year old sand bar that lies at the western edge of the bay’s opening into the Gulf of Mexico, impedes the freshwater flow of the Trinity and San Jacinto Rivers into the Gulf, the majority of which comes from the Trinity.

    2014-01-01

    Background The emergence of HIV as a chronic condition means that people living with HIV are required to take more responsibility for the self-management of their condition, including making physical, emotional and social adjustments. This paper describes the design and evaluation of Positive Outlook, an online program aiming to enhance the self-management skills of gay men living with HIV. Methods/design This study is designed as a randomised controlled trial in which men living with HIV in Australia will be assigned to either an intervention group or usual care control group. The intervention group will participate in the online group program ‘Positive Outlook’. The program is based on self-efficacy theory and uses a self-management approach to enhance skills, confidence and abilities to manage the psychosocial issues associated with HIV in daily life. Participants will access the program for a minimum of 90 minutes per week over seven weeks. Primary outcomes are domain specific self-efficacy, HIV related quality of life, and outcomes of health education. Secondary outcomes include: depression, anxiety and stress; general health and quality of life; adjustment to HIV; and social support. Data collection will take place at baseline, completion of the intervention (or eight weeks post randomisation) and at 12 week follow-up. Discussion Results of the Positive Outlook study will provide information regarding the effectiveness of online group programs improving health related outcomes for men living with HIV.

  13. 'The living death of Alzheimer's' versus 'Take a walk to keep dementia at bay': representations of dementia in print media and carer discourse.

    PubMed

    Peel, Elizabeth

    2014-07-01

    Understanding dementia is a pressing social challenge. This article draws on the 'Dementia talking: care conversation and communication' project which aims to understand how talk about, and to people living with dementia is constructed. In this article I draw on the construction of dementia manifest in two data sets - a corpus of 350 recent UK national newspaper articles and qualitative data derived from in-depth interviews with informal carers. These data were analysed using a thematic discursive approach. A 'panic-blame' framework was evident in much of the print media coverage. Dementia was represented in catastrophic terms as a 'tsunami' and 'worse than death', juxtaposed with coverage of individualistic behavioural change and lifestyle recommendations to 'stave off' the condition. Contrary to this media discourse, in carers' talk there was scant use of hyperbolic metaphor or reference to individual responsibility for dementia, and any corresponding blame and accountability. I argue that the presence of individualistic dementia 'preventative' behaviour in media discourse is problematic, especially in comparison to other more 'controllable' and treatable chronic conditions. Engagement with, and critique of, the nascent panic-blame cultural context may be fruitful in enhancing positive social change for people diagnosed with dementia and their carers.

    2013-04-01

    Living (Rose Bengal stained) benthic foraminiferal faunas were investigated at 13 deep-sea stations sampled in the Cap-Ferret Canyon area (NE Atlantic). One station (151 m) is located on the continental shelf close to the canyon head. All other stations are located along 2 bathymetric transects: 7 sites along the canyon axis with depths ranging from 300 to 3000 m and 5 stations along the adjacent flank with depths ranging from 300 m to 2000 m. Sedimentological analyses indicate that the Cap-Ferret Canyon is at present inactive in terms of sediment gravity flow. Compared to stations on the adjacent flank, canyon-axis stations are generally characterised by shallow oxygen penetration depths, high diffusive oxygen uptakes (DOU) and high lipid contents. Higher mineralisation rates recorded in the canyon axis are likely due to a preferential focusing of labile organic matter in the canyon axis. Foraminiferal standing stocks do not exhibit any straightforward correlation with the different descriptors of organic matter available in the sediment. However, foraminiferal standing stock and diversity along the canyon axis are generally higher than on the adjacent flank. Canyon axis sites yield dominant species that are similar to those at adjacent flank and open slope stations located at comparable water depths. However, intermediate and deep infaunal species were only recorded in the lower canyon axis, where high amounts of organic matter were observed in deeper sediment layers. Finally, the faunal composition in the Cap-Ferret Canyon is different compared to the nearby Cap-Breton Canyon, where sediment gravity flows are active. The absence of pioneer species and the occurrence of highly specialized taxa are both consistent with the much more stable conditions in terms of hydro-sedimentary conditions prevailing in the Cap-Ferret Canyon.

    2013-01-01

    Achieving and maintaining the water quality conditions necessary to protect the aquatic living resources of the Chesapeake Bay and its tidal tributaries has required a foundation of quantifiable water quality criteria. Quantitative criteria serve as a critical basis for assessing the attainment of designated uses and measuring progress toward meeting water quality goals of the Chesapeake Bay Program partnership. In 1987, the Chesapeake Bay Program partnership committed to defining the water quality conditions necessary to protect aquatic living resources. Under section 303(c) of the Clean Water Act, States and authorized tribes have the primary responsibility for adopting water quality standards into law or regulation. The Chesapeake Bay Program partnership worked with U.S. Environmental Protection Agency to develop and publish a guidance framework of ambient water quality criteria with designated uses and assessment procedures for dissolved oxygen, water clarity, and chlorophyll a for Chesapeake Bay and its tidal tributaries in 2003. This article reviews the derivation of the water quality criteria, criteria assessment protocols, designated use boundaries, and their refinements published in six addendum documents since 2003 and successfully adopted into each jurisdiction's water quality standards used in developing the Chesapeake Bay Total Maximum Daily Load.

    2013-07-01

    The prevalence of online modules for continuing education in the health professions has been increasing in recent years. However, the effectiveness of online modules for pharmacist learning has not been thoroughly studied. The primary aim of this study was to determine if providing education to pharmacists through a self-paced enhanced online module was non-inferior to a face-to-face learning module with respect to knowledge application on the topic of postoperative insulin dosing. Secondary aims were to determine pharmacists' knowledge gain and retention, as well as their satisfaction with the modules. The participants in this prospective, randomized, parallel-group non-inferiority trial were pharmacists in a large multicentre health region. Outcomes were measured by comparing scores obtained on pre- and post-module knowledge-assessment questionnaires. A between-group difference in change on knowledge application scores of less than 25 percentage points was the predetermined non-inferiority margin. A total of 74 pharmacists consented to participate, 38 randomly assigned to use the enhanced online module and 36 to attend the face-to-face learning session. For questions examining knowledge application, the mean improvement achieved by the online learning group was 26 percentage points greater than that achieved by the face-to-face learning group (95% confidence interval [CI] 25 to 27; p < 0.001). For questions testing knowledge gain, the improvement achieved by the online learning group was 7 percentage points less than that achieved by the face-to-face learning group (95% CI 2 to 12; p = 0.008). Therefore, the enhanced online module was deemed to be non-inferior to the face-to-face learning session in terms of knowledge application and knowledge gain. Insufficient data were available to analyze the secondary outcome of knowledge retention over time. Participant satisfaction was similar for the 2 groups (p = 0.62).

  7. What Online User Innovation Communities Can Teach Us about Capturing the Experiences of Patients Living with Chronic Health Conditions. A Scoping Review.

    PubMed

    Amann, Julia; Zanini, Claudia; Rubinelli, Sara

    2016-01-01

    In order to adapt to societal changes, healthcare systems need to switch from a disease orientation to a patient-centered approach. Virtual patient networks are a promising tool to favor this switch and much can be learned from the open and user innovation literature where the involvement of online user communities in the innovation process is well-documented. The objectives of this study were 1) to describe the use of online communities as a tool to capture and harness innovative ideas of end users or consumers; and 2) to point to the potential value and challenges of these virtual platforms to function as a tool to inform and promote patient-centered care in the context of chronic health conditions. A scoping review was conducted. A total of seven databases were searched for scientific articles published in English between 1995 and 2014. The search strategy was refined through an iterative process. A total of 144 studies were included in the review. Studies were coded inductively according to their research focus to identify groupings of papers. The first set of studies focused on the interplay of factors related to user roles, motivations, and behaviors that shape the innovation process within online communities.

    2016-01-01

    Background In order to adapt to societal changes, healthcare systems need to switch from a disease orientation to a patient-centered approach. Virtual patient networks are a promising tool to favor this switch and much can be learned from the open and user innovation literature where the involvement of online user communities in the innovation process is well-documented. Objectives The objectives of this study were 1) to describe the use of online communities as a tool to capture and harness innovative ideas of end users or consumers; and 2) to point to the potential value and challenges of these virtual platforms to function as a tool to inform and promote patient-centered care in the context of chronic health conditions. Methods A scoping review was conducted. A total of seven databases were searched for scientific articles published in English between 1995 and 2014. The search strategy was refined through an iterative process. Results A total of 144 studies were included in the review. Studies were coded inductively according to their research focus to identify groupings of papers. The first set of studies focused on the interplay of factors related to user roles, motivations, and behaviors that shape the innovation process within online communities. Studies of the second set examined the role of firms in online user innovation initiatives, identifying different organizational strategies and challenges. The third set of studies focused on the idea selection process and measures of success with respect to online user innovation initiatives. Finally, the findings from the review are presented in the light of the particularities and challenges discussed in current healthcare research. Conclusion The present paper highlights the potential of virtual patient communities to inform and promote patient-centered care, describes the key challenges involved in this process, and makes recommendations on how to address them.

    Tampa Bay, Florida,USA, is a shallow,subtropical estuary that experienced severe cultural eutrophication between the 1940s and 1980s, a period when the human population of its watershed quadrupled. In response, citizen action led to the formation of a public- and private-sector partnership (the Tampa Bay Estuary Program), which adopted a number of management objectives to support the restoration and protection of the bay’s living resources. These included numeric chlorophyll a and water-clarity targets, as well as long-term goals addressing the spatial extent of sea grasses and other selected habitat types, to support estuarine-dependent faunal guilds.

    Casco Bay lies at the heart of Maine's most populated area. The health of its waters, wetlands, and wildlife depend in large part on the activities of the quarter-million residents who live in its watershed. Less than 30 years ago, portions of Casco Bay were off-limits to recreation, fishing, and clamming. The lower Presumpscot River was devoid of fish, and paint peeling off nearby homes was attributed to the strong odor of chemicals emanating from the river. Back Cove and the Fore River were

    The Chesapeake Bay has a profound impact on the lives of all who reside in the 64,000 square miles of its watershed. From crab cakes to sail-boats, drinking water to naval ships, the Bay touches virtually every aspect of life in the region. The Bay has inspired literature, driven the regional economy, and shaped political decision making and development patterns for homes, industry, agriculture, and transportation. As population demands increase and urban boundaries expand into pristine landscapes, the sustainability of the Chesapeake Bay and its resources face unprecedented pressures. Consequently, the public's health also is vulnerable to Bay pollution and other stresses stemming from development activities and widespread growth occurring throughout the Chesapeake Bay watershed. This paper will examine the linkages between the environmental quality of the Bay and the population health status, recommend ways to bridge ecological and human health concerns in the context of the Bay, and finally present a framework for developing a public health report card for the Bay.

    Tampa Bay is Florida’s largest open-water estuary and encompasses an area of approximately 1036 km2 (400 mi2) (Burgan and Engle, 2006; TBNEP, 2006). The Bay’s watershed drains 5,698 km2 (2,200 mi2) of land and includes freshwater from the Hillsborough River to the north east, the Alafia and Little Manatee rivers to the east, and the Manatee River to the south (Figure 1). Freshwater inflow also enters the bay from the Lake Tarpon Canal, from small tidal tributaries, and from watershed runoff. Outflow travels from the upper bay segments (Hillsborough Bay and Old Tampa Bay) into Middle and Lower Tampa Bay. Southwestern portions of the water shed flow through Boca Ciega Bay into the Intracoastal Waterway and through the Southwest Channel and Passage Key Inlet into the Gulf of Mexico. The average depth in most of Tampa Bay is only 3.4 m (11 ft); however, 129 km (80 mi) of shipping channels with a maximum depth of 13.1 m (43 ft) have been dredged over time and are regularly maintained. These channels help to support the three ports within the bay, as well as commercial and recreational boat traffic.

    There is increasing evidence to support the effectiveness of eTherapies for mental health, although limited data have been reported from community-based services. Therefore, this service evaluation reports on feasibility and outcomes from an eTherapy mental health service. 'Self Help Services', an Increasing Access to Psychological Therapies (IAPT) eTherapy service in Greater Manchester. 1068 service users referred to the service for secondary care for their mental health difficulties. Participants were triaged into one of three eTherapy programmes: 'Living Life to the Full Interactive' for low mood, stress and anxiety; 'Sleepio' for insomnia; and 'Breaking Free Online' for substance misuse, depending on clinical need. Standardised psychometric assessments of depression, anxiety and social functioning, collected as part of the IAPT Minimum Data Set, were conducted at baseline and post-treatment. Data indicated baseline differences, with the Breaking Free Online group having higher scores for depression and anxiety than the Living Life to the Full Interactive (depression CI 1.27 to 3.21, p<0.0001; anxiety CI 077 to 1.72, p<0.0001) and Sleepio (depression CI 1.19 to 4.52, p<0.0001; anxiety CI 2.16 to 5.23, p<0.0001) groups. Promising improvements in mental health scores were found within all three groups (all p<0.0001), as were significant reductions in numbers of service users reaching clinical threshold scores for mental health difficulties (p<0.0001). Number of days of engagement was not related to change from baseline for the Living Life to the Full or Sleepio programmes but was associated with degree of change for Breaking Free Online. Data presented provide evidence for feasibility of this eTherapy delivery model in supporting service users with a range of mental health difficulties and suggest that eTherapies may be a useful addition to treatment offering in community-based services. © Article author(s) (or their employer(s) unless otherwise stated in the

    The whole of modern Bayesian statistical methods is founded on the simple idea of Bayes rule, stated by the Reverend Thomas Bayes, and presented in 1763. Bayes rule is merely a simple statement of conditional probablility but can be used to make strong inferences. However, the application of Bayes rule to all but the simplest problems requires significant computation. As a result, Baysian-based approaches have been largely impractical until high-speed computing became inexpensive in the recent in the last 20 years or so. We discuss the general idea behind Bayes rule, how to use it to build physical models, and illustrate the approach for a simple case of lattice gas models.

    Guanabara Bay is the second largest bay in the coast of Brazil, with an area of 384 km(2). In its surroundings live circa 16 million inhabitants, out of which 6 million live in Rio de Janeiro city, one of the largest cities of the country, and the host of the 2016 Olympic Games. Anthropogenic interference in Guanabara Bay area started early in the XVI century, but environmental impacts escalated from 1930, when this region underwent an industrialization process. Herein we present an overview of the current environmental and sanitary conditions of Guanabara Bay, a consequence of all these decades of impacts. We will focus on microbial communities, how they may affect higher trophic levels of the aquatic community and also human health. The anthropogenic impacts in the bay are flagged by heavy eutrophication and by the emergence of pathogenic microorganisms that are either carried by domestic and/or hospital waste (e.g., virus, KPC-producing bacteria, and fecal coliforms), or that proliferate in such conditions (e.g., vibrios). Antibiotic resistance genes are commonly found in metagenomes of Guanabara Bay planktonic microorganisms. Furthermore, eutrophication results in recurrent algal blooms, with signs of a shift toward flagellated, mixotrophic groups, including several potentially harmful species. A recent large-scale fish kill episode, and a long trend decrease in fish stocks also reflects the bay's degraded water quality. Although pollution of Guanabara Bay is not a recent problem, the hosting of the 2016 Olympic Games propelled the government to launch a series of plans to restore the bay's water quality. If all plans are fully implemented, the restoration of Guanabara Bay and its shores may be one of the best legacies of the Olympic Games in Rio de Janeiro.

  11. Phytoplankton bloom in the Bay of Biscay

    2017-09-27

    Springtime in the Bay of Biscay, off the coast of France, as in most places, is a season of abundant growth. On April 20, 2013, the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite captured this true-color image of the dynamic growth of a springtime phytoplankton bloom. The swirling colors indicate the presence of vast numbers of phytoplankton – tiny plant-like microorganisms that live in both fresh and salt water. Although these organisms live year-round in the Bay of Biscay, it is only when conditions are right that explosive blooms occur. In spring, the lengthening sunlight, the increased nutrient load swept into the Bay from ocean currents and from snowmelt carried by freshwater rivers, combined with warming waters create the perfect conditions to spur phytoplankton in to tremendous growth. The result is a swirling, multi-hued discoloration that can be easily seen from space. Each year, typically from March through April, such blooms occur in the Bay of Biscay. By May, however, conditions are not as favorable and the blooms fade, then disappear. Credit: NASA/GSFC/Jeff Schmaltz/MODIS Land Rapid Response Team NASA image use policy.

    The 1987 Chesapeake Bay Agreement committed the signatories to 'develop, adopt and begin implementation of a basinwide strategy to achieve a reduction of toxics, consistent with the Clean Water Act of 1987, which will ensure protection of human health and living resources.' The resultant Chesapeake Bay Basinwide Toxics Reduction Strategy, adopted by the Chesapeake Executive Council in January 1989, initiated a multi-jurisdictional effort to define the nature, extent, and magnitude of Chesapeake Bay toxics problems more accurately and initiate specific toxics reduction and prevention actions. The Chesapeake Bay Agreement signatories also committed to reevaluate the strategy during 1992. The objectives of this strategy reevaluation were to define: what we now know about the nature, extent, and magnitude of Bay toxics problems; what steps should be taken to reduce and prevent impacts from chemical contaminants; and what information is still needed to determine future actions. The Chesapeake Bay Program's Toxics Subcommittee investigated and evaluated the complex nature of the Bay's toxics problems through a two-year schedule of meetings, research workshops, and information-gathering forums. This report not only documents the findings of the two-year information gathering process of the strategy reevaluation but also recommends an approach for undertaking future toxics reduction and prevention actions in the Bay watershed.

    Hamelin Pool Marine Nature Reserve is located in the Shark Bay World Heritage Site in Western Australia. It is one of the very few places in the world where living stromatolites can be found. These are the first living examples of structures built by cyanobacteria. These bacteria are direct descendants of the oldest form of photosynthetic life on earth, dating back 3,500 million years (Wikipedia). The image was acquired December 30, 2010, covers an area of 34 x 46 km, and is located at 26.4 degrees south latitude, 114.1 degrees east longitude. With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.

  17. Mapping Oyster Reef Habitats in Mobile Bay

    NASA Technical Reports Server (NTRS)

    Bolte, Danielle

    2011-01-01

    Oyster reefs around the world are declining rapidly, and although they haven t received as much attention as coral reefs, they are just as important to their local ecosystems and economies. Oyster reefs provide habitats for many species of fish, invertebrates, and crustaceans, as well as the next generations of oysters. Oysters are also harvested from many of these reefs and are an important segment of many local economies, including that of Mobile Bay, where oysters rank in the top five commercial marine species both by landed weight and by dollar value. Although the remaining Mobile Bay oyster reefs are some of the least degraded in the world, projected climate change could have dramatic effects on the health of these important ecosystems. The viability of oyster reefs depends on water depth and temperature, appropriate pH and salinity levels, and the amount of dissolved oxygen in the water. Projected increases in sea level, changes in precipitation and runoff patterns, and changes in pH resulting from increases in the amount of carbon dioxide dissolved in the oceans could all affect the viability of oyster reefs in the future. Human activities such as dredging and unsustainable harvesting practices are also adversely impacting the oyster reefs. Fortunately, several projects are already under way to help rebuild or support existing or previously existing oyster reefs. The success of these projects will depend on the local effects of climate change on the current and potential habitats and man s ability to recognize and halt unsustainable harvesting practices. As the extent and health of the reefs changes, it will have impacts on the Mobile Bay ecosystem and economy, changing the resources available to the people who live there and to the rest of the country, since Mobile Bay is an important national source of seafood. This project identified potential climate change impacts on the oyster reefs of Mobile Bay, including the possible addition of newly viable

    A brief update on the destruction of the environment is given. The concern is for the coastal waters and rivers which are polluted daily by raw sewage, industrial waste, and sedimentation, e.g., the Juru in Malaysia, the Pasig in the Philippines, and the Chao Phraya in Thailand are open sewers by the time the rivers reach the sea or bay. Metropolitan Manila's river is said to be biologically dead from pollution, and the bays of Manila and Jakarta suffer from oxygen depletion. Unfortunately, the coastal area maintains population as well as the wealth of marine life. In the US in 1990, 75% of the population will live within 50 miles of a shore including the Great Lakes. 30 southeast Asia's 50 largest cities are located on or near a coast. Over fishing, over population, over developing, and over exploitation are unacceptable; the alternative is for man to correct his mistakes.

  6. Module bay with directed flow

    DOEpatents

    Torczynski, John R.

    2001-02-27

    A module bay requires less cleanroom airflow. A shaped gas inlet passage can allow cleanroom air into the module bay with flow velocity preferentially directed toward contaminant rich portions of a processing module in the module bay. Preferential gas flow direction can more efficiently purge contaminants from appropriate portions of the module bay, allowing a reduced cleanroom air flow rate for contaminant removal. A shelf extending from an air inlet slit in one wall of a module bay can direct air flowing therethrough toward contaminant-rich portions of the module bay, such as a junction between a lid and base of a processing module.

  10. The Neoglacial landscape and human history of Glacier Bay, Glacier Bay National Park and Preserve, southeast Alaska, USA

    2009-01-01

    The Neoglacial landscape of the Huna Tlingit homeland in Glacier Bay is recreated through new interpretations of the lower Bay's fjordal geomorphology, late Quaternary geology and its ethnographic landscape. Geological interpretation is enhanced by 38 radiocarbon dates compiled from published and unpublished sources, as well as 15 newly dated samples. Neoglacial changes in ice positions, outwash and lake extents are reconstructed for c. 5500?????"200 cal. yr ago, and portrayed as a set of three landscapes at 1600?????"1000, 500?????"300 and 300?????"200 cal. yr ago. This history reveals episodic ice advance towards the Bay mouth, transforming it from a fjordal seascape into a terrestrial environment dominated by glacier outwash sediments and ice-marginal lake features. This extensive outwash plain was building in lower Glacier Bay by at least 1600 cal. yr ago, and had filled the lower bay by 500 cal. yr ago. The geologic landscape evokes the human-described landscape found in the ethnographic literature. Neoglacial climate and landscape dynamism created difficult but endurable environmental conditions for the Huna Tlingit people living there. Choosing to cope with environmental hardship was perhaps preferable to the more severely deteriorating conditions outside of the Bay as well as conflicts with competing groups. The central portion of the outwash plain persisted until it was overridden by ice moving into Icy Strait between AD 1724?????"1794. This final ice advance was very abrupt after a prolonged still-stand, evicting the Huna Tlingit from their Glacier Bay homeland. ?? 2009 SAGE Publications.

    Guanabara Bay is the second largest bay in the coast of Brazil, with an area of 384 km2. In its surroundings live circa 16 million inhabitants, out of which 6 million live in Rio de Janeiro city, one of the largest cities of the country, and the host of the 2016 Olympic Games. Anthropogenic interference in Guanabara Bay area started early in the XVI century, but environmental impacts escalated from 1930, when this region underwent an industrialization process. Herein we present an overview of the current environmental and sanitary conditions of Guanabara Bay, a consequence of all these decades of impacts. We will focus on microbial communities, how they may affect higher trophic levels of the aquatic community and also human health. The anthropogenic impacts in the bay are flagged by heavy eutrophication and by the emergence of pathogenic microorganisms that are either carried by domestic and/or hospital waste (e.g., virus, KPC-producing bacteria, and fecal coliforms), or that proliferate in such conditions (e.g., vibrios). Antibiotic resistance genes are commonly found in metagenomes of Guanabara Bay planktonic microorganisms. Furthermore, eutrophication results in recurrent algal blooms, with signs of a shift toward flagellated, mixotrophic groups, including several potentially harmful species. A recent large-scale fish kill episode, and a long trend decrease in fish stocks also reflects the bay’s degraded water quality. Although pollution of Guanabara Bay is not a recent problem, the hosting of the 2016 Olympic Games propelled the government to launch a series of plans to restore the bay’s water quality. If all plans are fully implemented, the restoration of Guanabara Bay and its shores may be one of the best legacies of the Olympic Games in Rio de Janeiro. PMID:26635734

    The health of the James Bay Cree of Quebec reflects their history and environment. Their ancestors were living in Northern Quebec for centuries before the Europeans arrived bringing new infectious diseases and developing a health-care structure that has relegated traditional Cree medicine to the background. The James Bay and Northern Quebec Agreement of 1975 led to the creation of the Cree Board of Health and Social Services under the Quebec Ministry of Health. Various changes have resulted in the eight Cree villages over the past 15 years, both in the socio-economic situation and in the health status of the Cree. Improvements in health will come about through increased participation of Native people in the delivery and control of health services, more accessible health services, and the creation of healthy and health-promoting environments.

    The termination of studies carried on for almost three years in the Mobile Bay area and adjacent continental shelf are reported. The initial results concentrating on the shelf and lower bay were presented in the interim report. The continued scope of work was designed to attempt a refinement of the mathematical model, assess the effectiveness of optical measurement of suspended particulate material and disseminate the acquired information. The optical characteristics of particulate solutions are affected by density gradients within the medium, density of the suspended particles, particle size, particle shape, particle quality, albedo, and the angle of refracted light. Several of these are discussed in detail.

  18. What is causing the phytoplankton increase in San Francisco Bay?

    Cloern, J.E.; Jassby, A.D.; Schraga, T.S.; Dallas, K.L.

    2006-01-01

    The largest living component of San Francisco Bay is the phytoplankton, a suspension of microscopic cells that convert sunlight energy into new living biomass through the same process of photosynthesis used by land plants. This primary production is the ultimate source of food for clams, zooplankton, crabs, sardines, halibut, sturgeon, diving ducks, pelicans, and harbor seals. From measurements made in 1980, we estimated that phytoplankton primary production in San Francisco Bay was about 200,000 tons of organic carbon per year (Jassby et al. 1993). This is equivalent to producing the biomass of 5500 adult humpback whales, or the calories to feed 1.8 million people. These numbers may seem large, but primary production in San Francisco Bay is low compared to many other nutrient-enriched estuaries.

  20. Seasonal variations on the residence times and partitioning of short-lived radionuclides (234Th, 7Be and 210Pb) and depositional fluxes of 7Be and 210Pb in Tampa Bay, Florida

    USGS Publications Warehouse

    Baskaran, M.; Swarzenski, P.W.

    2007-01-01

    Historically, Tampa Bay has been impacted heavily by a wide range of anthropogenic perturbations that may include, agricultural-, shipping-, phosphate mining/distribution-related activities, as well as a burgeoning coastal population. Due to the presence of U-rich underlying sediments, elevated activities of U- and Th-series daughter products may be naturally released into this system. This region is also known for summer thunderstorms and corresponding increases in precipitation and surface water runoff. Only limited work has been conducted on the partitioning of particle-reactive radionuclides (such as 7Be, 210Pb, and 234Th) in such a dynamic coastal system. We investigated both the removal residence time and partitioning of these radionuclides between filter-retained particulate matter (≥ 0.5 μm) and the filtrate ( Our results indicate that the partitioning of 7Be, 210Pb, and 234Th between filtrate and filter-retained phase is controlled foremost by enhanced bottom resuspension events during summer thunderstorms. As a consequence, no significant relationship exists between the distribution coefficients (Kd values) of these isotopes and the concentration of suspended particulate matter (SPM). Relatively faster recycling rates of atmospheric water vapor derived from the ocean results in lower atmospheric depositional fluxes of 210Pb to the study site than predicted. The relationship between 7Be and 210Pb in bulk (wet + dry) deposition is compared to their respective water column activities. The residence times of particulate and dissolved 234Th, 7Be and 210Pb, as well the distribution coefficients of these radionuclides, are then compared to values reported in other coastal systems.

    The following is intended to be a short introduction to the design and analysis of a Bayes-optimal detector, and Middleton`s Locally Optimum Bayes Detector (LOBD). The relationship between these two detectors is clarified. There are three examples of varying complexity included to illustrate the design of these detectors. The final example illustrates the difficulty involved in choosing the bias function for the LOBD. For the examples, the corrupting noise is Gaussian. This allows for a relatively easy solution to the optimal and the LOBD structures. As will be shown, for Bayes detection, the threshold is determined by the costs associated with making a decision and the a priori probabilities of each hypothesis. The threshold of the test cannot be set by simulation. One will notice that the optimal Bayes detector and the LOBD look very much like the Neyman-Pearson optimal and locally optimal detectors respectively. In the latter cases though, the threshold is set by a constraint on the false alarm probability. Note that this allows the threshold to be set by simulation.

  12. Emerging behavior in online bidding

    Yang, I.; Kahng, B.

    2007-06-01

    With the advancement in the information age, people are using electronic media more frequently for commercial transactions. Online auction is a prototypical example. In online auctions, bidders or agents can easily participate into many different transactions simultaneously and the number of bidders participating in a given transaction is not bounded. Owing to such benefits, distinct features emerge compared with the traditional auctions, which are reviewed here. There form a number of bidders who are responsible for a significant fraction of the total bidding activities due to the online characteristics. We show that they exert strong influence on the final prices in distinct auctions. This domination of online auctions by such a unusually active minority may be a generic feature of all online mercantile processes. On the other hand, the bidding process in the auction systems is described by using a master equation with the transition probability determined with empirical data. We show that the bidding at the last moment is a rational and effective strategy to win in an eBay auction. Finally, the bidding pattern emerging from the interactions between individual bidders or items is analyzed in the perspective of the graph theory.

  13. Statistical Properties of Online Auctions

    NASA Astrophysics Data System (ADS)

    Namazi, Alireza; Schadschneider, Andreas

    We characterize the statistical properties of a large number of online auctions run on eBay. Both stationary and dynamic properties, like distributions of prices, number of bids etc., as well as relations between these quantities are studied. The analysis of the data reveals surprisingly simple distributions and relations, typically of power-law form. Based on these findings we introduce a simple method to identify suspicious auctions that could be influenced by a form of fraud known as shill bidding. Furthermore the influence of bidding strategies is discussed. The results indicate that the observed behavior is related to a mixture of agents using a variety of strategies.

    2016-01-01

    Although the last forty years has seen considerable growth in the use of statistics in legal proceedings, it is primarily classical statistical methods rather than Bayesian methods that have been used. Yet the Bayesian approach avoids many of the problems of classical statistics and is also well suited to a broader range of problems. This paper reviews the potential and actual use of Bayes in the law and explains the main reasons for its lack of impact on legal practice. These include misconceptions by the legal community about Bayes’ theorem, over-reliance on the use of the likelihood ratio and the lack of adoption of modern computational methods. We argue that Bayesian Networks (BNs), which automatically produce the necessary Bayesian calculations, provide an opportunity to address most concerns about using Bayes in the law. PMID:27398389

    Many living resources in the Chesapeake Bay estuary have deteriorated over the past 50 years. As a result, many governmental committees, task forces, and management plans have been established. Most of the recommendations for implementing a bay cleanup focus on reducing sediments and nutrient flow into the watershed. We emphasize that habitat requirements other than water quality are necessary for the recovery of much of the bay's avian wildlife, and we use a waterbird example as illustration. Some of these needs are: (1) protection of fast-eroding islands, or creation of new ones by dredge deposition to improve nesting habitat for American black ducks(Anas rubripes), great blue herons(Ardea herodias), and other associated wading birds; (2) conservation of remaining brackish marshes, especially near riparian areas, for feeding black ducks, wading birds, and wood ducks(Aix sponsa); (3) establishment of sanctuaries in open-water, littoral zones to protect feeding and/or roosting areas for diving ducks such as canvasbacks(Aythya valisineria) and redheads(Aythya americana), and for bald eagles(Haliaeetus leucocephalus); and (4) limitation of disturbance by boaters around nesting islands and open-water feeding areas. Land (or water) protection measures for waterbirds need to include units at several different spatial scales, ranging from ?points? (e.g., a colony site) to large-area resources (e.g., a marsh or tributary for feeding). Planning to conserve large areas of both land and water can be achieved following a biosphere reserve model. Existing interagency committees in the Chesapeake Bay Program could be more effective in developing such a model for wildlife and fisheries resources.

    Many living resources in the Chesapeake Bay estuary have deteriorated over the past 50 years. As a result, many governmental committees, task forces, and management plans have been established. Most of the recommendations for implementing a bay cleanup focus on reducing sediments and nutrient flow into the watershed. We emphasize that habitat requirements other than water quality are necessary for the recovery of much of the bay's avian wildlife, and we use a waterbird example as illustration. Some of these needs are: (1) protection of fast-eroding islands, or creation of new ones by dredge deposition to improve nesting habitat for American black ducks (Anas rubripes), great blue herons (Ardea herodias), and other associated wading birds; (2) conservation of remaining brackish marshes, especially near riparian areas, for feeding black ducks, wading birds, and wood ducks (Aix sponsa); (3) establishment of sanctuaries in open-water, littoral zones to protect feeding and/or roosting areas for diving ducks such as canvasbacks (Aythya valisineria) and redheads (Aythya americana), and for bald eagles (Haliaeetus leucocephalus); and (4) limitation of disturbance by boaters around nesting islands and open-water feeding areas. Land (or water) protection measures for waterbirds need to include units at several different spatial scales, ranging from “points” (e.g., a colony site) to large-area resources (e.g., a marsh or tributary for feeding). Planning to conserve large areas of both land and water can be achieved following a biosphere reserve model. Existing interagency committees in the Chesapeake Bay Program could be more effective in developing such a model for wildlife and fisheries resources.

    In this paper, the problem of designing a matched filter for image correlation will be treated as a statistical pattern recognition problem. It is shown that, by minimizing a suitable criterion, a matched filter can be estimated which approximates the optimum Bayes discriminant function in a least-squares sense. It is well known that the use of the Bayes discriminant function in target classification minimizes the Bayes risk, which in turn directly minimizes the probability of a false fix. A fast Fourier implementation of the minimum Bayes risk correlation procedure is described.

    HIV testing and serostatus awareness are essential to implement biomedical strategies (treatment as prevention; oral chemoprophylaxis), and for effective serostatus-based behaviours (HIV serosorting; strategic positioning). The analysis focuses on the associations between reported sexual risks, the perceived risk for HIV infection, and HIV testing behaviour in order to identify the most relevant barriers for HIV test uptake among MSM living in Germany. MSM were recruited to a nationwide anonymous online-survey in 2013 on MSM social networking/dating sites. Questions covered testing behaviours, reasons for testing decisions, and HIV risk perception (5-point scale). Additional questions addressed arguments in favour of home/ home collection testing (HT). Using descriptive statistics and logistic regression we compared men reporting recent HIV testing (RT; previous 12 month) with men never tested (NT) in a subsample not previously diagnosed with HIV and reporting ≥2 episodes of condomless anal intercourse (CLAI) with a non-steady partner of unknown HIV serostatus in the previous 12 months. The subsample consisted of 775 RT (13 % of RT) and 396 NT (7 % of NT). The number of CLAI episodes in the last 12 months with non-steady partners of unknown HIV status did not differ significantly between the groups, but RT reported significantly higher numbers of partners (>5 AI partners: 65 vs. 44 %). While perceived risks regarding last AI were comparable between the groups, 49vs. 30 % NT were <30 years, lived more often in towns/villages <100,000 residents (60 vs. 39 %), were less out-particularly towards care providers-about being attracted to men (aOR 10.1; 6.9-14.8), more often identified as bisexual (aOR 3.5; 2.5-4.8), and reported lower testing intentions (aOR 0.08; 0.06-0.11). Perceived risks (67 %) and routine testing (49 %) were the most common testing reasons for RT, while the strong belief not to be infected (59 %) and various worries (41 %) and fears of

    and Choke Canyon reservoir. The Corpus Christi Estuary receives approximately 35 percent of the total freshwater inflow of 1,480,178,205 cubic meters (m3 ) (1.2 million acre-feet) in the region; the Aransas Estuary receives about 53 percent. Tidal range is only 0.46 m (1.5 ft) on the Gulf shoreline and 0.15 m (0.5 ft) in Nueces Bay. Strong winds are the primary force behind water circulation in the Coastal Bend estuaries. The estuaries in Coastal Bend provide habitat and nutrition for many species of plants and animals, water purification, protection from storms, recreation and seafood, education, and maritime commerce (Holt, 1998). Coastal marshes comprise 45,729 hectares (113,000 acres), or 11 percent, of the aquatic habitats in Coastal Bend. There are 835 species of plants and 2,340 species of animals, including nearly 500 species of birds, in the Coastal Bend Bays area, not including those species that remain unidentified. Nineteen of these species are threatened or endangered. The only remaining natural population of the endangered whooping crane winters at Aransas National Wildlife Refuge. As the population of the Coastal Bend region grows, the amount of use and stress on the estuaries increases. Approximately 3 percent of Texas’ population—560,000 people in 2000—live in Coastal Bend (Holt, 1998; Handley and others, 2007). Corpus Christi, whose population was estimated at over 316,000 in 2013 (U.S. Census Bureau, 2010), is the only city in Coastal Bend with a population greater than 20,000. 3 Agriculture, oil and gas production, manufacturing and shipping, national defense, and tourism dominate the economy in the Coastal Bend Bay area. Petroleum and chemical industries generate the most revenue, whereas tourism and military activities provide the most jobs. Oil production generates over $300 million, and gas production generates nearly $700 million each year. Approximately 25 percent of the jobs held in the Coastal Bend are related to tourism.

    Background Elevated stress can exacerbate cancer symptom severity, and after completion of primary cancer treatments, many individuals continue to have significant distress. Mindfulness-Based Cancer Recovery (MBCR) is an 8-week group psychosocial intervention consisting of training in mindfulness meditation and yoga designed to mitigate stress, pain, and chronic illness. Efficacy research shows face-to-face (F2F) MBCR programs have positive benefits for cancer patients; however barriers exist that impede participation in F2F groups. While online MBCR groups are available to the public, none have been evaluated. Primary objective: determine whether underserved patients are willing to participate in and complete an online MBCR program. Secondary objectives: determine whether online MBCR will mirror previous efficacy findings from F2F MBCR groups on patient-reported outcomes. Method/design The study includes cancer patients in Alberta, exhibiting moderate distress, who do not have access to F2F MBCR. Participants will be randomized to either online MBCR, or waiting for the next available group. An anticipated sample size of 64 participants will complete measures online pre and post treatment or waiting period. Feasibility will be tracked through monitoring numbers eligible and participating through each stage of the protocol. Discussion 47 have completed/completing the intervention. Data suggest it is possible to conduct a randomized waitlist controlled trial of online MBCR to reach underserved cancer survivors.

    The document provides guidance for Chesapeake Bay resource managers and others on how existing submerged aquatic vegetation (SAV) and tidal shallow water habitats with potential for supporting SAV in the Bay can be fully protected, given current human uses of and demands on the Bay. In preparing this guidance document, the Submerged Aquatic Vegetation (SAV) Workgroup of the Chesapeake Bay Program`s Living Resources Subcommittee reviewed, summarized, and compared current state and federal policies and guidelines for protection of or minimizing impacts on SAV. Next, the workgroup identified key management issues facing the protection of existing and future SAV resources. Finally, building on current state and federal guidelines and policies, the workgroup identified guidance to first avoid, then minimize, direct impacts to SAV in the Bay and its tidal tributaries.

    The authors are developing a computer application, called the Bayes Inference Engine, to provide the means to make inferences about models of physical reality within a Bayesian framework. The construction of complex nonlinear models is achieved by a fully object-oriented design. The models are represented by a data-flow diagram that may be manipulated by the analyst through a graphical programming environment. Maximum a posteriori solutions are achieved using a general, gradient-based optimization algorithm. The application incorporates a new technique of estimating and visualizing the uncertainties in specific aspects of the model.

  6. Soundscape Ecology of Hawaiian Spinner Dolphin Resting Bays

    NASA Astrophysics Data System (ADS)

    Heenehan, Heather Leigh

    Sound is a key sensory modality for Hawaiian spinner dolphins. Like many other marine animals, these dolphins rely on sound and their acoustic environment for many aspects of their daily lives, making it is essential to understand soundscape in areas that are critical to their survival. Hawaiian spinner dolphins rest during the day in shallow coastal areas and forage offshore at night. In my dissertation I focus on the soundscape of the bays where Hawaiian spinner dolphins rest taking a soundscape ecology approach. I primarily relied on passive acoustic monitoring using four DSG-Ocean acoustic loggers in four Hawaiian spinner dolphin resting bays on the Kona Coast of Hawai'i Island. 30-second recordings were made every four minutes in each of the bays for 20 to 27 months between January 8, 2011 and March 30, 2013. I also utilized concomitant vessel-based visual surveys in the four bays to provide context for these recordings. In my first chapter I used the contributions of the dolphins to the soundscape to monitor presence in the bays and found the degree of presence varied greatly from less than 40% to nearly 90% of days monitored with dolphins present. Having established these bays as important to the animals, in my second chapter I explored the many components of their resting bay soundscape and evaluated the influence of natural and human events on the soundscape. I characterized the overall soundscape in each of the four bays, used the tsunami event of March 2011 to approximate a natural soundscape and identified all loud daytime outliers. Overall, sound levels were consistently louder at night and quieter during the daytime due to the sounds from snapping shrimp. In fact, peak Hawaiian spinner dolphin resting time co-occurs with the quietest part of the day. However, I also found that humans drastically alter this daytime soundscape with sound from offshore aquaculture, vessel sound and military mid-frequency active sonar. During one recorded mid

    Chesapeake Bay, one of the world's largest estuaries, has experienced deterioration of water quality from nutrient enrichment, resulting in anoxic or hypoxic conditions and declines in living resources. Determination of relationships between water quality and various living resources provides a mechanism of relating anthropogenic inputs to the 'health' of Chesapeake Bay. One of the major factors contributing to the high productivity of Chesapeake Bay has been the historical abundance of submerged aquatic vegetation (SAV). SAV in Chesapeake Bay include some twenty freshwater and marine species of rooted, flowering plants. SAV provide food for waterfowl and are critical habitat for shellfish and finfish. SAV also affect nutrient cycling, sediment stability, and water turbidity. The primary objective of the SAV Technical Synthesis is to establish the quantitative levels of relevant water quality parameters necessary to support continued survival, propagation, and restoration of SAV.

    Biological and water resource data for Tampa Bay were compiled and mapped at a scale of 1:24,000. This atlas consists of (1) composited information overlain on 18 biological and 20 water resource base maps and (2) an accompanying map narrative. Subjects mapped on the water resource maps are contours of the mean middepth specific conductivity which can be converted to salinity; bathymetry, sediments, tidal currents, the freshwater/saltwater interface, dredge spoil disposal sites; locations of industrial and municipal point source discharges, tide stations, and water quality sampling stations. The point source discharge locations show permitted capacity and the water quality sampling stations show 5-year averages for chlorophyll, conductivity, turbidity, temperature, and total nitrogen. The subjects shown on the biological resource maps are clam and oyster beds, shellfish harvest areas, colonial bird nesting sites, manatee habitat, seagrass beds and artificial reefs. Spawning seasons, nursery habitats, and adult habitats are identified for major fish species. The atlas will provide useful information for coastal planning and management in Tampa Bay.

  17. Bay of Fundy

    2006-01-01

    The highest tides on Earth occur in the Minas Basin, the eastern extremity of the Bay of Fundy, Nova Scotia, Canada, where the tide range can reach 16 meters when the various factors affecting the tides are in phase. The primary cause of the immense tides of Fundy is a resonance of the Bay of Fundy-Gulf of Maine system. The system is effectively bounded at this outer end by the edge of the continental shelf with its approximately 40:1 increase in depth. The system has a natural period of approximately 13 hours, which is close to the 12h25m period of the dominant lunar tide of the Atlantic Ocean. Like a father pushing his daughter on a swing, the gentle Atlantic tidal pulse pushes the waters of the Bay of Fundy-Gulf of Maine basin at nearly the optimum frequency to cause a large to-and-fro oscillation. The greatest slosh occurs at the head (northeast end) of the system. The high tide image (top) was acquired April 20, 2001, and the low tide image (bottom) was acquired September 30, 2002. The images cover an area of 16.5 by 21 km, and are centered near 64 degrees west longitude and 45.5 degrees north latitude.

    With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

    The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active

  8. Assessing Sustainable Developments in a Coastal Region: the Garolim Bay in the West Coast of Korea

    NASA Astrophysics Data System (ADS)

    Park, M. J.

    2016-12-01

    The Garolim Bay is a semi-enclosed bay located in the west coast of Korea and has a spring tidal range over 6 m. It is well known for vast tidal flats and healthy ecosystems that supports high productive and diverse marine lives. Due to its large tidal range it was considered favorable site for the construction of tidal power plant and went through controversies over decades. Local fishermen depending on their livelihood over generations strongly opposed the construction, so did the most environmental groups. They argued that construction of the tidal barrage at the entrance of the bay will reduce the tidal range resulting in increase of mud content of bottom sediments and disruption of marine lives. On the other hand, the power generation industry and some local residents supported the construction arguing that the tidal power is renewable energy and contributes to reduction of CO2 emission along with economic benefits from tourists' sightseeing of the tidal power plant. The application of the tidal power plant construction at the Garolim Bay was not approved by the Korean government due to the concerns of environmental impacts on the marine lives of the Garolim Bay region. This study briefly reviews developments associated with the tidal power plant construction in the Garolim Bay and considers how to approach the assessment of the sustainable development of the coastal region of the Garolim Bay in accordance with UN Sustainable Development Goals (SDG) 2030 with appropriate goals, targets and monitoring indicators. It will be of keen interests to policy makers of central and local governments as well as local residents to monitor and find out the benefits pursuing SDG in the Garolim Bay where conflicts of interests among stakeholders persisted, and may exemplify the case for other regions of similar situations.

    USGS Publications Warehouse

    Morrison, Gerold; Greening, Holly; Yates, Kimberly K.; Wolanski, Eric; McLusky, Donald S.

    2011-01-01

    Tampa Bay, Florida, USA, is a shallow, subtropical estuary that experienced severe cultural eutrophication between the 1940s and 1980s, a period when the human population of its watershed quadrupled. In response, citizen action led to the formation of a public- and private-sector partnership (the Tampa Bay Estuary Program), which adopted a number of management objectives to support the restoration and protection of the bay’s living resources. These included numeric chlorophyll a and water-clarity targets, as well as long-term goals addressing the spatial extent of seagrasses and other selected habitat types, to support estuarine-dependent faunal guilds. Over the past three decades, nitrogen controls involving sources such as wastewater treatment plants, stormwater conveyance systems, fertilizer manufacturing and shipping operations, and power plants have been undertaken to meet these and other management objectives. Cumulatively, these controls have resulted in a 60% reduction in annual total nitrogen (TN) loads relative to earlier worse-case (latter 1970s) conditions. As a result, annual water-clarity and chlorophyll a targets are currently met in most years, and seagrass cover measured in 2008 was the highest recorded since 1950. Factors that have contributed to the observed improvements in Tampa Bay over the past several decades include the following: (1) Development of numeric, science-based water-quality targets to meet a long-term goal of restoring seagrass acreage to 1950s levels. Empirical and mechanistic models found that annual average chlorophyll a concentrations were a primary manageable factor affecting light attenuation. The models also quantified relationships between TN loads, chlorophyll a concentrations, light attenuation, and fluctuations in seagrass cover. The availability of long-term monitoring data, and a systematic process for using the data to evaluate the effectiveness of management actions, has allowed managers to track progress and

  1. Spatial variation of phytoplankton community structure in Daya Bay, China.

    2015-10-01

    Daya Bay is one of the largest and most important gulfs in the southern coast of China, in the northern part of the South China Sea. The phylogenetic diversity and spatial distribution of phytoplankton from the Daya Bay surface water and the relationship with the in situ water environment were investigated by the clone library of the large subunit of ribulose-1, 5-bisphosphate carboxylase (rbcL) gene. The dominant species of phytoplankton were diatoms and eustigmatophytes, which accounted for 81.9 % of all the clones of the rbcL genes. Prymnesiophytes were widely spread and wide varieties lived in Daya Bay, whereas the quantity was limited. The community structure of phytoplankton was shaped by pH and salinity and the concentration of silicate, phosphorus and nitrite. The phytoplankton biomass was significantly positively affected by phosphorus and nitrite but negatively by salinity and pH. Therefore, the phytoplankton distribution and biomass from Daya Bay were doubly affected by anthropic activities and natural factors.

    The ability of resource agencies to manage fish, wildlife and freshwater supplies of San Francisco Bay estuary requires an integrated knowledge of the relations between the biota and their physical environment. A key factor in these relations is the role of salinity in determining both the physical and the biological character of the estuary. The saltiness of the water, and particularly its seasonal and interannual patterns of variability, affects which aquatic species live where within the estuary. Salinity also determines where water can and cannot be diverted for human consumption and irrigated agriculture, and plays a role in determining the capacity of the estuary to cleanse itself of wastes. In short, salinity is a fundamental property of estuarine physics and chemistry that, in turn, determines the biological characteristics of each estuary. Freshwater is a major control on estuarine salinity. Most freshwater supplied to the Bay is from river flow through the Delta, which is primarily runoff from the Sierra Nevada. Most contaminants in San Francisco Bay are from the Sacramento/San Joaquin Valley and the local watershed around the Bay rather than the sea or atmosphere. Land is the primary source of freshwater and freshwater serves as a tracer of land-derived substances such as the trace metals (copper, lead and selenium), pesticides and plant nutrients (nitrate and phosphate). The U.S. Geological Survey is collaborating with other agencies and institutions in studying San Francisco Bay salinity using field observations and numerical simulations to define the physical processes that control salinity. The issues that arise from salinity fluctuations, however, differ in the northern and southern parts of the bay. In North Bay we need to know how salinity responds to freshwater flow through the Sacramento/San Joaquin Delta; this knowledge will benefit water managers who determine how much delta flow is needed a) to protect freshwater supplies for municipal water

  3. Tsunami Inundation modeling for Tolaga Bay, Tokomaru Bay, Hicks Bay and Te Araroa communities

    NASA Astrophysics Data System (ADS)

    Barberopoulou, A.; Wang, X.; Power, W. L.

    2012-12-01

    We assess the tsunami hazard to four communities in Raukumara Peninsula (Northeastern region of North Island of New Zealand): Tokomaru Bay, Tolaga Bay, Hicks Bay and Te Araroa. Representative severe but realistic scenarios that could affect the Raukumara peninsula are earthquakes that rupture the interface between the Australian and Pacific plates, earthquakes that rupture faults within the overlying Australian plate or the subducting Pacific plate (location is not always well constrained). Earthquakes that rupture both the plate interface and simultaneously faults within the crust of the Australian plate are also a possibility. Tsunamis may also be caused by submarine landslides that occur near the edge of the continental shelf, but these are not considered here. For this study four scenario events were constructed, including a distant event from South America (offshore Peru), outer rise events and a thrust event in the Hikurangi region off the east coast of New Zealand. The sources are not exhaustive but representative of the types of significant events that could occur in the region and were either improved from earlier sources or derived from recent studies. Available high resolution LiDAR and RTK data were combined with topographic and LINZ data for the development of bathymetric/topographic grids. Our modelling results show that Tolaga Bay appears most vulnerable to tsunami inundation although Hicks Bay and Te Araroa are also significantly inundated in several of the scenarios. Tokomaru Bay is naturally well protected because the rapid change in elevation limits the range of inundation. The worst scenario for Tokomaru Bay was an earthquake in the Hikurangi subduction zone resulting in large flow depths, whereas for Tolaga Bay inundation is severe from most scenarios. Hicks Bay and Te Araroa get the most severe flooding from earthquakes in South America and on the Hikurangi subduction zone. Inundation extent is similar for Tolaga Bay during the Outer Rise and

  4. Estimation of Response Functions Based on Variational Bayes Algorithm in Dynamic Images Sequences

    PubMed Central

    2016-01-01

    We proposed a nonparametric Bayesian model based on variational Bayes algorithm to estimate the response functions in dynamic medical imaging. In dynamic renal scintigraphy, the impulse response or retention functions are rather complicated and finding a suitable parametric form is problematic. In this paper, we estimated the response functions using nonparametric Bayesian priors. These priors were designed to favor desirable properties of the functions, such as sparsity or smoothness. These assumptions were used within hierarchical priors of the variational Bayes algorithm. We performed our algorithm on the real online dataset of dynamic renal scintigraphy. The results demonstrated that this algorithm improved the estimation of response functions with nonparametric priors. PMID:27631007

  5. Using Bayes to get the most out of non-significant results

    PubMed Central

    Dienes, Zoltan

    2014-01-01

    No scientific conclusion follows automatically from a statistically non-significant result, yet people routinely use non-significant results to guide conclusions about the status of theories (or the effectiveness of practices). To know whether a non-significant result counts against a theory, or if it just indicates data insensitivity, researchers must use one of: power, intervals (such as confidence or credibility intervals), or else an indicator of the relative evidence for one theory over another, such as a Bayes factor. I argue Bayes factors allow theory to be linked to data in a way that overcomes the weaknesses of the other approaches. Specifically, Bayes factors use the data themselves to determine their sensitivity in distinguishing theories (unlike power), and they make use of those aspects of a theory’s predictions that are often easiest to specify (unlike power and intervals, which require specifying the minimal interesting value in order to address theory). Bayes factors provide a coherent approach to determining whether non-significant results support a null hypothesis over a theory, or whether the data are just insensitive. They allow accepting and rejecting the null hypothesis to be put on an equal footing. Concrete examples are provided to indicate the range of application of a simple online Bayes calculator, which reveal both the strengths and weaknesses of Bayes factors. PMID:25120503

  6. Mackenzie Bay, Antarctica

    NASA Image and Video Library

    2017-09-28

    Off the northeastern edge of Antarctica’s Amery Ice Shelf lies Mackenzie Bay, which was painted with a ghostly blue-green mass in early February 2012. Similarly colored tendrils also streamed northward across the ocean, their flow sometimes interrupted by icebergs. Multiple factors might account for the ghostly shapes, including low-lying clouds or katabatic winds—downslope winds blowing toward the coast, which can freeze the water at the ocean surface. But an intriguing and perhaps more likely explanation involves processes occurring below the ice shelf. An ice shelf is a thick slab of ice often fed by glaciers attached to the coastline. The shelf floats on the ocean surface, with seawater circulating underneath. Like most ice shelves, the Amery is very thick in the upstream area near the shore. It thins significantly as it stretches northward away from the continent. Water at depth is subject to much greater pressure than water at the surface, and one effect of this intense pressure is that it effectively lowers the freezing point. So water circulating at depth beneath the Amery Ice Shelf may be slightly below the temperature at which it would normally begin to freeze. As some that water wells up along the underbelly of the shelf, the pressure is reduced and the water begins to freeze even though the temperature may not change. As it freezes, this deep-ocean water forms needle-like crystals known as frazil. The crystals are only 3 to 4 millimeters (0.12 to 0.16 inches) wide, but a sufficient concentration of frazil can change the appearance of the water. A frazil-rich plume probably accounts for the blue-green waters off the Amery Ice Shelf in the image above. Modeling of ocean circulation beneath the shelf indicates just such a plume emerging in that location. Frazil-rich water explains the plume, and wind transport of the surface water explains the long streams extending northward. As the sub-iceshelf water mixes with surface water around the Antarctic

    Layout design is one of the most important activities done by industrial Engineers. Most of these problems have NP hard Complexity. In a basic layout design, each cell is represented by a rectilinear, but not necessarily convex polygon. The set of fully packed adjacent polygons is known as a block layout (Asef-Vaziri and Laporte 2007). Block layout is divided by slicing tree and bay layout. In bay layout, departments are located in vertical columns or horizontal rows, bays. Bay layout is used in real worlds especially in concepts such as semiconductor and aisles. There are several reviews in facility layout; however none of them focus on bay layout. The literature analysis given here is not limited to specific considerations about bay layout design. We present a state of art review for bay layout considering some issues such as the used objectives, the techniques of solving and the integration methods in bay.

  6. Contaminant transport in Massachusetts Bay

    USGS Publications Warehouse

    Butman, Bradford

    Construction of a new treatment plant and outfall to clean up Boston Harbor is currently one of the world's largest public works projects, costing about $4 billion. There is concern about the long-term impact of contaminants on Massachusetts Bay and adjacent Gulf of Maine because these areas are used extensively for transportation, recreation, fishing, and tourism, as well as waste disposal. Public concern also focuses on Stellwagen Bank, located on the eastern side of Massachusetts Bay, which is an important habitat for endangered whales. Contaminants reach Massachusetts Bay not only from Boston Harbor, but from other coastal communities on the Gulf of Maine, as well as from the atmosphere. Knowledge of the pathways, mechanisms, and rates at which pollutants are transported throughout these coastal environments is needed to address a wide range of management questions.

    A report on April 25, 1988 by the Environmental Defense Fund blames acid rain for pollution of Chesapeake Bay. The nitrates in the rain are reported to account for 25% of the nitrogen load of the bay. This increases the acidity of the bay, thereby acting as a fertilizer to promote algal growth. It is postulated that acid rain contributes as much nitrogen to the bay as point sources, which include raw sewage and industrial plants.

    2006-01-01

    In April 2004, more than 40 hours of georeferenced submarine digital video was collected in water depths of 15-370 m in Glacier Bay to (1) ground-truth existing geophysical data (bathymetry and acoustic reflectance), (2) examine and record geologic characteristics of the sea floor, and (3) investigate the relation between substrate types and benthic communities, and (4) construct predictive maps of seafloor geomorphology and habitat distribution. Common substrates observed include rock, boulders, cobbles, rippled sand, bioturbated mud, and extensive beds of living horse mussels and scallops. Four principal sea-floor geomorphic types are distinguished by using video observations. Their distribution in lower and central Glacier Bay is predicted using a supervised, hierarchical decision-tree statistical classification of geophysical data.

  9. Chesapeake Bay habitat restoration: A framework for action

    SciTech Connect

    1995-10-01

    This framework for action enhances existing Chesapeake Bay Program strategies, policies, and implementation plans, while providing a foundation for integrated restoration for integrated restoration activities. Based on an increased understanding of landscape and watershed processes, the framework targets the need of specific living resources in four target habitat areas through on-the-ground restoration projects. Moreover, decision-making will improve as we strengthen our ability to target, integrate, and restore key habitat functions via three phases outlined in the framework: Phase I: Facilitate habitat restoration projects, research and monitoring immediately. Phase II: Develop a process for targeting habitat restoration projects within a landscape or watershed framework. Phase II: Foster partnerships that use the expertise of federal, state, and local governments and public and private efforts to implement effective restoration projects throughout the Chesapeake Bay watershed, using the targeting information provided in Phase II.

  10. Sediment Sources and Storage in the Chesapeake Bay Watershed

    Physically and chemically, sediment is a pollutant of concern in many waterbodies. In the Chesapeake Bay, sediment is having an adverse effect on the living resources and habitat of the Chesapeake Bay and its watershed. Identifying significant sources of watershed sediment is important in reducing sediment loads. In the Chesapeake Bay, several approaches were used to understand the sources, transport, and storage of watershed-derived sediment. From 1985 through 2001, the U.S. Geological Survey collected suspended sediment at 35 stations draining portions of the 103,000 km2 Chesapeake Bay. Of the 35 sites, 4 of the 6 highest sediment yields were in the Conestoga River Basin, Pennsylvania, which drains to the Susquehanna River. In the Susquehanna River Basin (43,600 km2), erosion rates were determined using atmospheric 10Be at 92 river outlets and confirmed that the highest rates of erosion were in the Conestoga River Basin. In three small watersheds draining to the Chesapeake Bay -- the Pocomoke River (157 km2), Little Conestoga Creek (68.1 km2), and Mattawoman Creek (92.8 km2) -- sediment sources were identified using a sediment-source identification approach. In this approach, the sources of fine-grained suspended sediment in transport can be established by comparing physical and chemical properties of the suspended sediment to potential sources. In this study, suspended sediment (< 0.062 mm) collected during storm runoff was compared to upland sediment sources (cropland, construction sites, and forest) and channel corridor sources (channel banks and bed) using radionuclides (210Pb, 137Cs), stable isotopes (13C, 15N), and total C, N, and P. Preliminary results are available for two of the three watersheds. In the Pocomoke River watershed, which drains the Coastal Plain physiographic province, ditch beds which were dug to drain cropland were a significant source of sediment. In the Little Conestoga Creek watershed, which drains the Piedmont physiographic province

  11. A summary report of sediment processes in Chesapeake Bay and watershed

    USGS Publications Warehouse

    Langland, Michael; Cronin, Thomas

    2003-01-01

    The Chesapeake Bay, the Nation's largest estuary, has been degraded because of diminished water quality, loss of habitat, and over-harvesting of living resources. Consequently, the bay was listed as an impaired water body due to excess nutrients and sediment. The Chesapeake Bay Program (CBP), a multi-jurisdictional partnership, completed an agreement called ?Chesapeake 2000? that revises and establishes new restoration goals through 2010 in the bay and its watershed. The goal of this commitment is the removal of the bay from the list of impaired waterbodies by the year 2010. The CBP is committed to developing sediment and nutrient allocations for major basins within the bay watershed and to the process of examining new and innovative management plans in the estuary itself and along the coastal zones of the bay. However, additional information is required on the sources, transport, and deposition of sediment that affect water clarity. Because the information and data on sediment processes in the bay were not readily accessible to the CBP or to state, and local managers, a Sediment Workgroup (SWGP) was created in 2001. The primary objective of this report, therefore, is to provide a review of the literature on the sources, transport, and delivery of sediment in Chesapeake Bay and its watershed with discussion of potential implications for various management alternatives. The authors of the report have extracted, discussed, and summarized the important aspects of sediment and sedimentation that are most relevant to the CBP and other sediment related-issues with which resources managers are involved. This report summarizes the most relevant studies concerning sediment sources, transport and deposition in the watershed and estuary, sediments and relation to water clarity, and provides an extensive list of references for those wanting more information.

    LANDSAT images with enhancement and density slicing show that the Chesapeake Bay plume usually frequents the Virginia coast south of the Bay mouth. Southwestern (compared to northern) winds spread the plume easterly over a large area. Ebb tide images (compared to flood tide images) show a more dispersed plume. Flooding waters produce high turbidity levels over the shallow northern portion of the Bay mouth.

    The small Asian clam, Potamocorbula amurensis, is now a major component of benthic communities in most areas of northern San Francisco Bay and some areas of South Bay. Because of its wide tolerance of salinity and other environmental variables and its high abundance in many areas, benthic ecologists believe this recent invasion may represent a major and permanent change in the bay system.

  6. Mobile Bay turbidity plume study

    Crozier, G. F.

    1976-01-01

    Laboratory and field transmissometer studies on the effect of suspended particulate material upon the appearance of water are reported. Quantitative correlations were developed between remotely sensed image density, optical sea truth data, and actual sediment load. Evaluation of satellite image sea truth data for an offshore plume projects contours of transmissivity for two different tidal phases. Data clearly demonstrate the speed of change and movement of the optical plume for water patterns associated with the mouth of Mobile bay in which relatively clear Gulf of Mexico water enters the bay on the eastern side. Data show that wind stress in excess of 15 knots has a marked impact in producing suspended sediment loads.

  8. Bayes' postulate for trinomial trials

    NASA Astrophysics Data System (ADS)

    Diniz, M. A.; Polpo, A.

    2012-10-01

    In this paper, we discuss Bayes' postulate and its interpretation. We extend the binomial trial method proposed by de Finetti [1] to trinomial trials, for which we argue that the consideration of equiprobability a priori for the possible outcomes of the trinomial trials implies that the parameter vector has Dirichlet(1,1) as prior. Based on this result, we agree with Stigler [2] in that the notion in Bayes' postulate stating "absolutely know nothing" is related to the possible outcomes of an experiment and not to "non-information" about the parameter.

    NASA Astrophysics Data System (ADS)

    Thomas, Helmuth; Shadwick, Elizabeth H.; Dehairs, Frank; Gratton, Yves

    2013-04-01

    The Arctic Ocean and its carbon cycle are expected to be disproportionately sensitive to climatic change and, thus the Arctic is thought to be an area where such changes may most easily be detected. In particular the carbon cycle in polar ocean is vulnerable due to the relatively high Revelle factor and correspondingly weaker CO2 buffer capacity. The Arctic ocean is influenced by runoff and precipitation, sea ice formation and melting, and the inflow of saline waters from Bering and Fram Straits as well as the Barents Sea Shelf. Pacific water is recognizable as low(er) salinity water, with high concentrations of dissolved inorganic carbon, flowing from the Arctic Ocean to the North Atlantic via the Canadian Arctic Archipelago. In the Baffin Bay area, at the eastern entrance to the Canadian Arctic Archipelago, the water masses of three major oceans meet. Atlantic Ocean water traveling into Baffin Bay as the east Greenland current mixes with waters from the Arctic Ocean and the Pacific Ocean, which enter Baffin Bay via Nares Strait and various outflows of the Canadian Arctic Archipelago, before the waters head southward along the western side of Baffin Bay, eventually feeding into the Labrador Current and the North Atlantic Ocean. Altered mixing ratios of these three water masses and freshwater in the Arctic Ocean have been recorded in recent decades. Any climatically driven alterations in the composition of waters leaving Baffin Bay may have implications for anthropogenic CO2 uptake and, hence, acidification, of the subpolar and temperate North Atlantic. We present carbon cycle, Barium and stable oxygen isotope composition data of sea water and related data from two east to west section across Baffin Bay at 75N and 76N as well as from shelf sections long the eastern and western shelves of Baffin Bay. We investigate water mass characteristics and mixing pattern of the above three major water masses in Baffin Bay. The data have been collected in the framework of two

  11. Bayes factors and multimodel inference

    USGS Publications Warehouse

    Link, W.A.; Barker, R.J.; Thomson, David L.; Cooch, Evan G.; Conroy, Michael J.

    2009-01-01

    Multimodel inference has two main themes: model selection, and model averaging. Model averaging is a means of making inference conditional on a model set, rather than on a selected model, allowing formal recognition of the uncertainty associated with model choice. The Bayesian paradigm provides a natural framework for model averaging, and provides a context for evaluation of the commonly used AIC weights. We review Bayesian multimodel inference, noting the importance of Bayes factors. Noting the sensitivity of Bayes factors to the choice of priors on parameters, we define and propose nonpreferential priors as offering a reasonable standard for objective multimodel inference.

In previous studies, Bayes' theorem has been used for this purpose. This approach requires a means to map continuously distributed experimental data to probabilities (likelihood values) to derive posterior probabilities from the combination of prior probabilities and new data. Here, we introduce the use of minimum Bayes' factors for this purpose and illustrate the approach by addressing a physiological question, "Which deubiquitylating enzymes (DUBs) encoded by mammalian genomes are most likely to regulate plasma membrane transport processes in renal cortical collecting duct principal cells?" To do this, we have created a comprehensive online database of 110 DUBs present in the mammalian genome (https://hpcwebapps.cit.nih.gov/ESBL/Database/DUBs/). We used Bayes' theorem to integrate available information from large-scale data sets derived from proteomic and transcriptomic studies of renal collecting duct cells to rank the 110 known DUBs with regard to likelihood of interacting with and regulating transport processes. The top-ranked DUBs were OTUB1, USP14, PSMD7, PSMD14, USP7, USP9X, OTUD4, USP10, and UCHL5. Among these USP7, USP9X, OTUD4, and USP10 are known to be involved in endosomal trafficking and have potential roles in endosomal recycling of plasma membrane proteins in the mammalian cortical collecting duct.

    In this ASTER image the features that look like folded material are carbonate sand dunes in the shallow waters of Tarpum Bay, southwest of Eleuthera Island in the Bahamas. The sand making up the dunes comes from the erosion of limestone coral reefs, and has been shaped into dunes by ocean currents.

    This image was acquired on May 12, 2002 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

    The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

  6. A review of benthic faunal surveys in San Francisco Bay

    USGS Publications Warehouse

    Nichols, Frederic H.

    1973-01-01

    During the past 60 years, considerable effort has been expended in studies of the relations of the biotic community and physicochemical characteristics of San Francisco Bay water. In very recent years these studies have emphasized the relations between the 'state of health' of bottom-living invertebrates (the benthos) and the levels of pollutants in the bay. Benthic organisms, generally sessile, are unable to escape deleterious environmental changes, and they reflect these changes in alterations of normal species composition of assemblages and species abundance. Data that expands understanding of these relations in urbanized areas such as San Francisco Bay are critical. Because of the implications of such data in control of water quality, the U.S. Geological Survey undertook a review of the results and major conclusions of San Francisco Bay benthic surveys. The size and species composition of faunal assemblages are largely controlled by the salinity of the water, the texture of the bottom sediments, and locally by wastes discharged into the bay. Efforts to describe the structure and function of benthic communities of the bay and to quantify the effects of waste discharge on them have been hampered by inconsistent and often faulty sampling methodology and species identification. Studies made show a lack of information on the normal life processes of the organisms concerned. The diversity index (a mathematical expression of the number of kinds of organisms present at a location), commonly used to describe the 'health' of the benthic community, has been employed without regard for the need for standardizing methodology and species identifications or for understanding natural biological processes that affect such mathematical indices. There are few reliable quantitative data on the distribution of benthic organisms in San Francisco Bay with which future assessments of the 'health' of the benthic community might be compared. Methods for study of the benthos must be

  7. The U.S. Geological Survey and the Chesapeake Bay; the role of science in environmental restoration

    USGS Publications Warehouse

    Phillips, Scott

    2002-01-01

    The Chesapeake Bay is the Nation's largest estuary and historically supported one of the most productive fisheries in the world. In addition to supporting aquatic communities and wildlife, the bay's watershed serves the economic and recreational needs of 15 million people. The fertile soils of the watershed support significant agricultural production. Unfortunately, the commercial, economic, and recreational value of the bay and its watershed has been degraded by poor water quality, loss of habitat, and overharvesting of living resources. Since the early 1980's, the Chesapeake Bay Program, which is a partnership among Maryland, Virginia, Pennsylvania, the District of Columbia, the Federal Government, and the Chesapeake Bay Commission, has been formulating and implementing restoration goals to restore living resources, minimize habitat loss, and reduce the amount of nutrients, sediment, and toxic substances entering the bay. The U.S. Geological Survey has the critical role of providing unbiased scientific information to be used in helping to formulate, implement, and assess the effectiveness of restoration goals in the bay and its watershed.

  8. Coprostanol as a potential tracer of particulate sewage effluent to shelf waters adjacent to the Chesapeake Bay

    NASA Technical Reports Server (NTRS)

    Brown, R. C.; Wade, T. L.

    1981-01-01

    Samples were collected in the Chesapeake Bay entrance and contiguous shelf waters and were subsequently analyzed for particulate coprostanol and cholesterol concentrations. Surface coprostanol concentrations were fairly uniform, with a slight increase with depth. This increase with depth may be due to sewage-associated particulates settling as they leave the Bay, or the resuspension of contaminated sediment. Preliminary findings indicate sewage-associated materials are being transported from the Chesapeake Bay to shelf waters, where they may have a detrimental affect on living marine resources.

  16. Bayes' estimators of generalized entropies

    Holste, D.; Große, I.; Herzel, H.

    1998-03-01

    The order-q Tsallis 0305-4470/31/11/007/img5 and Rényi entropy 0305-4470/31/11/007/img6 receive broad applications in the statistical analysis of complex phenomena. A generic problem arises, however, when these entropies need to be estimated from observed data. The finite size of data sets can lead to serious systematic and statistical errors in numerical estimates. In this paper, we focus upon the problem of estimating generalized entropies from finite samples and derive the Bayes estimator of the order-q Tsallis entropy, including the order-1 (i.e. the Shannon) entropy, under the assumption of a uniform prior probability density. The Bayes estimator yields, in general, the smallest mean-quadratic deviation from the true parameter as compared with any other estimator. Exploiting the functional relationship between 0305-4470/31/11/007/img7 and 0305-4470/31/11/007/img8, we use the Bayes estimator of 0305-4470/31/11/007/img7 to estimate the Rényi entropy 0305-4470/31/11/007/img8. We compare these novel estimators with the frequency-count estimators for 0305-4470/31/11/007/img7 and 0305-4470/31/11/007/img8. We find by numerical simulations that the Bayes estimator reduces statistical errors of order-q entropy estimates for Bernoulli as well as for higher-order Markov processes derived from the complete genome of the prokaryote Haemophilus influenzae.

    The elongated semi-enclosed Bay of Izmit, which receives both domestic and industrial wastes, has been monitored by measuring its physical and biochemical parameters for 2 years, 1994-1995. It is clear that there are two distinct water masses. The upper layer has been occupied by the less saline (22-26 ppt) waters of the Black Sea origin; whereas the lower layer contains saline (38.5 ppt) Mediterranean waters. The seasonal variations in the biochemical characteristics were dependent on the bay's two-layer flow system. If one considers the distribution of transparency in the upper bay waters, it has been observed that the Secchi disk depth (SDD) decreases from west to east. Furthermore, these depths are limited by the high primary productivity associated with the low concentrations of nutrients observed during the spring. Discharges of wastes into the surface waters significantly affect the biological production and oxygen consumption in the lower layer. Within the last 10 years, 80% of organic matter has been removed from industrial wastewater. However, organic loads from the domestic wastewaters have doubled because of the growth in the surrounding population. Fortunately, as a result, the total organic loads in the bay have not changed significantly within the last 10 years.

    The Daya Bay Reactor Neutrino Experiment was designed to measure θ 13, the smallest mixing angle in the three-neutrino mixing framework, with unprecedented precision. The experiment consists of eight functionally identical detectors placed underground at different baselines from three pairs of nuclear reactors in South China. Since Dec. 2011, the experiment has been running stably for more than 4 years, and has collected the largest reactor anti-neutrino sample to date. Daya Bay is able to greatly improve the precision on θ 13 and to make an independent measurement of the effective mass splitting in the electron antineutrino disappearance channel. Daya Bay can also perform a number of other precise measurements, such as a high-statistics determination of the absolute reactor antineutrino flux and spectrum, as well as a search for sterile neutrino mixing, among others. The most recent results from Daya Bay are discussed in this paper, as well as the current status and future prospects of the experiment.

    Mobile Bay, and large mammals such as the red wolf, Florida panther, and Florida black bear are no longer found in the area. However, some rare species, such as the swallow-tailed kite, sandhill crane, and gopher tortoise can still be found (Duke and Kruczynski, 1992). The value of wetlands in Mobile Bay and the rest of the Gulf of Mexico is still being investigated. Although various monetary valuations of wetlands exist, critics remark that undervaluation of wetlands is inevitable (Mobile Bay NEP, 2008) and that estimates often do not place appropriate value on ecological services (Mitsch and Gosselink, 2000). Additionally, many estimates account only for anthropogenic values. One estimate concludes that one acre of wetlands performs \\$3,000 worth of water purification each year (Mobile Bay NEP, 1997). With more than 76,890 hectares (190,000 acres) of wetlands in the Mobile Bay area, that equates to a value exceeding one-half billion dollars every year. Tourism, fishing, boating, production, and shipping are significant industries in the Mobile Bay area. More than 90% of fish landed in recreational and commercial fishing in the bay depend on bay habitat, including wetlands, for life requirements (Mobile Bay NEP, 1997). The Port of Mobile is Alabama’s only ocean-ship port (Mobile Bay NEP, 2008). Baldwin County, on the eastern side of the bay, experienced a population increase of 75% from 1990 to 2007, with an 89% increase in housing units (Mobile Bay NEP, 2008). Development and industry support the Mobile Bay economy, but they depend on the continued health, sustainability, and production of the water and living resources of the Mobile Bay ecosystem. Wetland loss, along with other forms of environmental degradation, remains a threat to the Mobile Bay ecosystem and Mobile Bay’s socioeconomic foundation.

    Nuclear-reaction network codes are important to astronomers seeking to explore nucleosynthetic implications of astrophysical models and to nuclear physicists seeking to understand the role of nuclear properties or reaction rates in element formation. However, many users do not have the time or inclination to download and compile the codes, to manage the requisite input files, or to explore the often complex output with their own graphics programs. To help make nucleosynthesis calculations more readily available, we have placed the Clemson Nucleosynthesis code on the world-wide web at http://www.ces.clemson.edu/physics/nucleo/nuclearNetwork At this web site, any Internet user may set his or her own reaction network, nuclear properties and reaction rates, and thermodynamic trajectories. The user then submits the nucleosynthesis calculation, which runs on a dedicated server professionally maintained at Clemson University. Once the calculation is completed, the user may explore the results through dynamically produced and downloadable tables and graphs. Online help guides the user through the necessary steps. We hope this web site will prove a user-friendly and helpful tool for professional scientists as well as for students seeking to explore element formation.

  8. Data Management Solutions for Tracking Restoration Progress in the Chesapeake Bay Watershed

    Ravi, S. R.; Johnston, M.; Sweeney, J.

    2014-12-01

    The decline of the Chesapeake Bay estuarine ecosystem due to agricultural and industrial activities has been a great concern, where excess of dissolved nutrients combined with global climate change has lead to increased storm surges, habitat destruction, and low dissolved oxygen, reduced water clarity, and increased algal growth. In 2010 The US Environmental Protection Agency established the Chesapeake Bay Total Maximum Daily Load (TMDL), which seeks to protect the Bay's living resources by reducing nutrient and sediment runoff to its waters, and sets pollution reduction targets for sediment, nitrogen and phosphorus across 64000 sq. miles watershed that includes parts of six states - Delaware, Maryland, New York, Pennsylvania, Virginia, and West Virginia — and the entire District of Columbia. The Chesapeake Bay Program and the US EPA have developed a number of tools to track the progress of restoration. In this study we describe data management solutions, which were used in the integration of data such as land use, nutrient applications, management practices, policies among the bay jurisdictions, and a summary of a suite of tools that were developed and are being used to collect, process, and report data at various spatial scales for tracking the progress made by the seven Bay jurisdictions in achieving reductions in nutrient and sediment runoff. The described integration strategy and data management solutions can be used in the development and application of similar regulatory local or regional scale environmental management tools.

    The Chesapeake 2000 Agreement committed its state and federal signatories to "define the water quality conditions necessary to protect aquatic living resources" in the Chesapeake Bay (USA) and its tidal tributaries. Hypoxia is one of the key water quality issues addressed as a result of the above Agreement. This paper summarizes the protection goals and specific criteria intended to achieve those goals for addressing hypoxia. The criteria take into account the variety of Bay habitats and the tendency towards low dissolved oxygen in some areas of the Bay. Stressful dissolved oxygen conditions were characterized for a diverse array of living resources of the Chesapeake Bay by different aquatic habitats: migratory fish spawning and nursery, shallow-water, open-water, deep-water, and deep-channel. The dissolved oxygen criteria derived for each of these habitats are intended to protect against adverse effects on survival, growth, reproduction and behavior. The criteria accommodate both spatial and temporal aspects of low oxygen events, and have been adopted into the Chesapeake Bay states - Maryland, Virginia, and Delaware - and the District of Columbia's water quality standards regulations. These criteria, now in the form of state regulatory standards, are driving an array of land-based and wastewater pollution reduction actions across the six-watershed.

    2004-02-01

    A survey of 11 positive features and 10 discouraging features of online shopping was carried out on 180 students and identified certain behavioral patterns for online shoppers versus non-shoppers. It was found that online shoppers have consistently stronger positive feelings about online shopping than do non-shoppers. On the other hand, non-shoppers have more negative feelings about online shopping than do shoppers, but not consistently so. Online shoppers are aware of some of the discouraging features of online shopping, but these features do not deter them from shopping online. The implication for marketers is that they should focus on making the experience of online shopping more accommodating and more user-friendly since the positive features of online shopping ("convenience" and "efficiency") appear to be more important than the negative features ("effort/impersonality").

  6. Factors Influencing Spatial and Annual Variability in Eelgrass (Zostera marina L.) Meadows in Willapa Bay, Washington, and Coos Bay, Oregon, Estuaries

    2003-08-01

    Environmental factors that influence annual variability and spatial differences in eelgrass meadows (Zostera marina L.) were examined within Willapa Bay, WA, and Coos Bay, OR, over a period of 4 years (1998-2001). A suite of eelgrass metrics were recorded annually at field sites that spanned the estuarine gradient from the marine-dominated to mesohaline regions. Growth of eelgrass plants was also monitored on a monthly basis within Sequim Bay, WA. Both the spatial cover and density of Z. marina were positively correlated with estuarine salinity and inversely correlated with temperature of the tideflat sediment. Experimental evidence verified that optimal eelgrass growth occurred at highest salinities and relatively low temperatures. Eelgrass density, biomass, and the incident of flowering plants all increased substantially in Willapa Bay, and less so in Coos Bay, over the duration of the study. Warmer winters and cooler summers associated with the transition from El Ni?o to La Ni?a ocean conditions during the study period were correlated with the increase in eelgrass abundance and flowering. Anthropogenic factors (e.g., disturbance and erosion by vessel wakes and recreational shellfishing activities) may have contributed to spatial variability. Our findings indicate that large-scale changes in climate and nearshore ocean conditions can exert a strong regional influence on eelgrass abundance, which can vary annually by as much as 700% in Willapa Bay. Lower levels of variability observed in Coos Bay may be due to the stronger and more direct influence of the nearshore Pacific Ocean. We conclude that climate variation may have profound effects on the abundance and distribution of eelgrass meadows throughout the Pacific Northwest, and we anticipate that ocean conditions will emerge as a primary driving force for living estuarine resources and ecological processes that are associated with Z. marina beds within the landscape of these estuarine tidal basins.

  7. The San Francisco Bay Biota Since the Last Sea Level Maximum: Comparing Fossil and Recent Assemblages of Benthic Foraminifera

    2004-12-01

    Comparisons of fossil and Recent foraminiferal assemblages in San Francisco Bay can give us information about how the Bay's ecosystems have changed or remained resilient during the glacial cycles of the Pleistocene. This information, in turn, can help us to predict the potential impact of future environmental change on this system. In this study, we compared the species proportions, overall similarity, and species diversity of the Recent foraminiferal assemblage at one site in South San Francisco Bay with the fossil foraminiferal assemblage from Pleistocene samples taken at several sites in South San Francisco Bay, in order to test the hypothesis that the foraminiferal assemblage in San Francisco Bay has not changed significantly since the last interglacial interval. Comparisons of total sample similarity indicate that the upper layer of the Yerba Buena mud was deposited during conditions similar to today's South San Francisco Bay. The presence of a large number of dead tests of Elphidium gunteri Cole and Elphidiella hannai (Cushman and Grant), together with the lack of living populations of these species in South San Francsico Bay, make it difficult to interpret the presence of these taxa in similar abundances in the Plestocene and today. Possibly due to the introduction of the Japanese foraminifer Trochammina hadai Uchio, the modern assemblage has shifted away from the dominance of Elphidium excavatum (Terquem) found in the Pleistocene. Species diversity has neither decreased nor increased between the Pleistocene and the present day in South San Francisco Bay, suggesting that environmental change and human activity has not affected species diversity of the benthic foraminiferal fauna. These data show that comparisons between fossil and Recent assemblages are powerful tools in interpreting paleoenvironments, and may help us to understand the impact of human activity on estuarine and other marine systems. More research is needed on the living populations of E

  8. Guide to the littoral zone vascular flora of Carolina bay lakes (U.S.A.)

    2016-01-01

    Abstract Background Carolina bays are elliptic, directionally aligned basins of disputed origin that occur on the Atlantic Coastal Plain from the Delmarva Peninsula to southern Georgia. In southeastern North Carolina, several large, natural, lacustrine systems (i.e., Carolina bay lakes) exist within the geomorphological features known as Carolina bays. Within the current distribution of Carolina bays, Bladen and Columbus counties (North Carolina) contain the only known examples of Carolina bay lakes. The Carolina bay lakes can be split into two major divisions, the “Bladen Lakes Group” which is characterized as being relatively unproductive (dystrophic – oligotrophic), and Lake Waccamaw, which stands alone in Columbus County and is known for its high productivity and species richness. Although there have been several studies conducted on these unique lentic systems, none have documented the flora comprehensively. New information Over the 2013−2014 growing seasons, the littoral zone flora of Carolina bay lakes was surveyed and vouchered. Literature reviews and herbarium crawls complemented this fieldwork to produce an inventory of the vascular plant species. This survey detected 205 taxa (species/subspecies and varieties) in 136 genera and 80 vascular plant families. Thirty-one species (15.2%) are of conservation concern. Lake Waccamaw exhibited the highest species richness with 145 catalogued taxa and 26 species of conservation concern. Across all sites, the Cyperaceae (25 spp.), Poaceae (21 spp.), Asteraceae (13 spp.), Ericaceae (8 spp.), Juncaceae (8 spp.), and Lentibulariaceae (6 spp.) were the six most species-rich vascular plant families encountered. A guide to the littoral zone flora of Carolina bay lakes is presented herein, including dichotomous keys, species accounts (including abundance, habitat, phenology, and exsiccatae), as well as images of living species and vouchered specimens.

    Live benthic foraminiferal assemblages from surface sediment in Osaka Bay collected in 1999 were analyzed to characterize the distribution of the modern foraminiferal assemblages. Foraminiferal assemblages were compared with those of previous studies to document environmental changes in Osaka Bay over the past 50 years. Sixty-one species of foraminifera belonging to 37 genera were recognized from the 1999 surface sediment samples. An agglutinated assemblage containing Trochammina hadai and Eggerella advena is dominant in the inner part of the bay and is related to eutrophication. The foraminiferal assemblage in areas deeper than about 20 m is composed of Eggerella advena, Ammonia beccarii forma A, and Pseudorotalia gaimardii. This assemblage may be influenced by the large clockwise Okinose Circulation Current which extends throughout the western bay. Foraminiferal assemblages in Osaka Bay have changed dramatically during the last 50 years. The Trochammina hadai-Eggerella advena assemblage became established in the inner part of the bay, reflecting eutrophication that progressed from the 1960s through the 1970s. This assemblage became dominant in 1983, and typically dominated the inner part of the bay. From 1983 to 1999, however, the abundance of taxa belonging to this assemblage decreased greatly following implementation of 1973 Osaka City bylaws that restricted wastewater discharge. Changes in benthic assemblages such as the decrease of Ammonia beccarii forma A and increase of Eggerella advena have occurred in response to decreased incidence of red tides, and floral change in the species that cause these tides. The results of this study demonstrate that the abundance and distribution of benthic foraminifers in Osaka Bay are intimately related to environmental changes related to the urbanization of coastal areas. ?? by the Palaeontological Society of Japan.

    International Polar Year presents an extraordinary opportunity to educate students and the public about science at the icy ends of the Earth. The goal of our proposal is to apply collaborative multimedia approaches to bring the story of four polar research expeditions to the general public and the classroom. The four expeditions (measurement of ice sheet dynamics in Greenland, a study of the McMurdo ecosystem over austral winter, installation of a buoy array in the Beaufort Gyre, and exploration of the Gakkel Ridge) were chosen based on their broad range of disciplines and relevance to the three primary IPY research emphasis areas defined by NSF. A science writer and a professional photographer will join each expedition and file dispatches for a daily Webcast. The posting will feature science updates, logistical challenges, team member profiles, and life at sea (or on the ice). The writer will also coordinate real-time phone patches from PIs in the field to audiences at the Museum of Science, Boston, the Smithsonian National Museum of Natural History, The Field Museum, Chicago, the Houston Museum of Natural Science, the Birch Aquarium, San Diego, the Pacific Science Center, Seattle, National Public Radio "Talk of the Nation: Science Friday," CBS News, and to student "reporters" writing for Scholastic Online. At the museums, the "Live from the Ice" interactive phone calls will be preceded by a background presentation by a scientist, who will also moderate the live discussion between the public and researchers in the field. A 20-30 minute satellite phone call will allow the public to ask the researchers questions about their research while it's happening. In addition to building and promoting an online experience, a museum exhibit featuring models of Arctic instruments and informative kiosks will be developed at the Woods Hole Oceanographic Institution Exhibit Center. Each of our partner museums will also provide a "leave-behind" component to continue to educate

  19. The Chesapeake Bay impact structure

    Powars, David S.; Edwards, Lucy E.; Gohn, Gregory S.; Horton, J. Wright

    2015-10-28

    About 35 million years ago, during late Eocene time, a 2-mile-wide asteroid or comet smashed into Earth in what is now the lower Chesapeake Bay in Virginia. The oceanic impact vaporized, melted, fractured, and (or) displaced the target rocks and sediments and sent billions of tons of water, sediments, and rocks into the air. Glassy particles of solidified melt rock rained down as far away as Texas and the Caribbean. Models suggest that even up to 50 miles away the velocity of the intensely hot air blast was greater than 1,500 miles per hour, and ground shaking was equivalent to an earthquake greater than magnitude 8.0 on the Richter scale. Large tsunamis affected most of the North Atlantic basin. The Chesapeake Bay impact structure is among the 20 largest known impact structures on Earth.

  20. Nelson River and Hudson Bay

    2002-01-01

    Rivers that empty into large bodies of water can have a significant impact on the thawing of nearshore winter ice. This true-color Moderate Resolution Imaging Spectroradiometer (MODIS) image from May 18, 2001, shows the Nelson River emptying spring runoff from the Manitoba province to the south into the southwestern corner of Canada's Hudson Bay. The warmer waters from more southern latitudes hasten melting of ice near the shore, though some still remained, perhaps because in shallow coastal waters, the ice could have been anchored to the bottom. High volumes of sediment in the runoff turned the inflow brown, and the rim of the retreating ice has taken on a dirty appearance even far to the east of the river's entrance into the Bay. The sediment would have further hastened the melting of the ice because its darker color would have absorbed more solar radiation than cleaner, whiter ice.

  1. Sedimentary Controls on Foraminifera Distribution in the Bay of Bengal

    IODP Expedition 354 drilled sites in the Bay of Bengal to improve our understanding of the links between tectonics, monsoon strength, and oceanographic conditions. The Bengal Fan contains complex depositional environments, which vary from thick sequences of turbidites and levee sediments that reflects channel activity, to intervals of hemipelagic calcareous clay. Foraminifera are commonly used to reconstruct past oceanographic conditions, but the complex depositional environments raises the possibility that foraminifera in the cores were transported from the northern Bay of Bengal through turbidity currents, rather than settling out from the overlying water column. The goal of the project is to determine if foraminifera in the modern sediments at IODP Exp 354 sites record the overlying water column conditions or water conditions of the northern Bay of Bengal. Today sea surface salinity (SSS) and sea surface temperature (SST) has a larger seasonal range in the northern bay (3.0 psu and 5ᵒC, respectively) compared to Exp 354 core sites at 8ᵒN (0.7 psu and 1.4ᵒC, respectively). We present Mg/Ca and d18O data of individual Globigerinoides ruber or sacculifer in the mud-line samples of site U1454 (8.4ᵒN, 85.5ᵒE, 3721 m water depth), which is near the modern active channel, and site U1449 (8.4ᵒN, 88.7ᵒE, 3653 m water depth), which is farthest from the active channel. Because foraminifera live ~2-4 weeks, each analysis reflects a short period of time. Taken together, the distribution of 75 to 100 data points will reflect the seasonal SST and SSS range where the foraminifera calcified. Given the spatial variability of seasonality in the Bay of Bengal, a broader distribution of the data would reflect the larger SSS and SST range of the northern bay, while a narrower data distribution would reflect the much smaller SSS and SST range at the Exp 354 location. If foraminifera at both sites reflect local surface water conditions we can be more confident in applying

    Yellow perch live in creeks, rivers, ponds, lakes, and estuaries across the central and eastern United States and Canada. In Chesapeake Bay, they tolerate salinities up to one-third that of seawater. The adults reside in the brackish waters of the bay’s tributaries and migrate upstream to spawn. Yellow perch are eagerly sought by recreational fishermen for their excellent taste and, because their late winter spawning runs are the earliest of the year, they are regarded as a harbinger of spring. Yellow perch also support a small but valuable, tightly regulated commercial fishery in the part of Chesapeake Bay that lies in Maryland.

    2003-05-01

    The utility of Bayes' theorem in paleopathological diagnoses is explored. Since this theorem has been used heavily by modern clinical medicine, its usefulness in that field is described first. Next, the mechanics of the theorem are discussed, along with methods for deriving the prior probabilities needed for its application. Following this, the sources of these prior probabilities and their accompanying problems in paleopathology are considered. Finally, an application using prehistoric rib lesions is presented to demonstrate the utility of this method to paleopathology.

    Leizhou coastal marine area, Liusha Bay and Shenzhen Bay represented open coastal area and half-closed bay, respectively. This study discussed the differences of PAHs concentration levels, spatial distribution and sources in sediments from these three marine areas. The results showed that detected ratios of 15 PAHs were 100%, and major compounds were 3-ring and 4-ring PAHs, especialy Phe, Fla, Pry and Bbf; Sigma PAHs concentration was Leizhou < Shenzhen < Liusha. In spatial distribution, PAHs concentrations were the east < the south < the west in Leizhou; the inside > the outside, and the aquaculture > the non-aquaculture in Liusha Bay and Shenzhen Bay. It suggested that large-scale mariculture inside bay played an important role in PAHs pollution and might make it serious. Oil, fossil fuels and biomass burning were the dominant sources of PAHs in sediments from Leizhou coastal area, Liusha Bay and Shenzhen Bay.

  9. Terra Nova Bay Polynya, Antarctica

    NASA Technical Reports Server (NTRS)

    2007-01-01

    In Terra Nova Bay, off the Scott Coast of Victoria Land, Antarctica, a large pocket of open water persists throughout most of the Southern Hemisphere winter, even while most of the rest of the Antarctic coastline is firmly embraced by the frozen Southern Ocean. This pocket of open water--a polynya--results from exceptionally strong winds that blow downslope from the Trans-Antarctic Mountains. These fierce katabatic winds drive the sea ice eastward. Since the dominant ice drift pattern in the area is northward, the Drygalski Ice Tongue prevents the bay from being re-populated with sea ice. This image of the Terra Nova Bay polynya was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite on October 16, 2007. Sea ice sits over the Ross Sea like a cracked and crumbling windshield. Blue-tinged glaciers flow down from the Trans-Antarctic Mountains. Although glaciers can appear blue because of melt water, they can also get that tint when the wind scours and polishes the ice surface. Given the strength of the katabatic winds along this part of the Antarctic coast, it is likely that the blue color of these glaciers is a result of their having been swept clean of snow. The large image has a spatial resolution (level of detail) of 250 meters per pixel.

  10. Lithospheric Architecture Beneath Hudson Bay

    2015-12-01

    Hudson Bay overlies some of the thickest Precambrian lithosphere on Earth, whose internal structures contain important clues to the earliest workings of plate formation. The terminal collision, the Trans-Hudson Orogen, brought together the Western Churchill craton to the northwest and the Superior craton to the southeast. These two Archean cratons along with the Paleo-Proterozoic Trans-Hudson internides, form the core of the North American craton. We use S to P converted wave imaging and absolute shear velocity information from a joint inversion of P to S receiver functions, new ambient noise derived phase velocities, and teleseismic phase velocities to investigate this region and determine both the thickness of the lithosphere and the presence of internal discontinuities. The lithosphere under central Hudson Bay approaches 􏰂350 km thick but is thinner (􏰂200-250 km) around the periphery of the Bay. Furthermore, the amplitude of the lithosphere-asthenosphere boundary (LAB) conversion from the S receiver functions is unusually large for a craton, suggesting a large thermal contrast across the LAB, which we interpret as direct evidence of the thermal insulation effect of continents on the asthenosphere. Within the lithosphere, midlithospheric discontinuities, significantly shallower than the base of the lithosphere, are often imaged, suggesting the mechanisms that form these layers are common. Lacking time-history information, we infer that these discontinuities reflect reactivation of formation structures during deformation of the craton.

These two Archean cratons along with the Paleo-Proterozoic Trans-Hudson internides, form the core of the North American craton. We use S to P converted wave imaging and absolute shear velocity information from a joint inversion of P to S receiver functions, new ambient noise derived phase velocities, and teleseismic phase velocities to investigate this region and determine both the thickness of the lithosphere and the presence of internal discontinuities. The lithosphere under central Hudson Bay approaches ˜350 km thick but is thinner (˜200-250 km) around the periphery of the Bay. Furthermore, the amplitude of the LAB conversion from the S receiver functions is unusually large for a craton, suggesting a large thermal contrast across the LAB, which we interpret as direct evidence of the thermal insulation effect of continents on the asthenosphere. Within the lithosphere, midlithospheric discontinuities, significantly shallower than the base of the lithosphere, are often imaged, suggesting the mechanisms that form these layers are common. Lacking time-history information, we infer that these discontinuities reflect reactivation of formation structures during deformation of the craton.

  12. Terra Nova Bay Polynya, Antarctica

    NASA Technical Reports Server (NTRS)

    2007-01-01

    In Terra Nova Bay, off the Scott Coast of Victoria Land, Antarctica, a large pocket of open water persists throughout most of the Southern Hemisphere winter, even while most of the rest of the Antarctic coastline is firmly embraced by the frozen Southern Ocean. This pocket of open water--a polynya--results from exceptionally strong winds that blow downslope from the Trans-Antarctic Mountains. These fierce katabatic winds drive the sea ice eastward. Since the dominant ice drift pattern in the area is northward, the Drygalski Ice Tongue prevents the bay from being re-populated with sea ice. This image of the Terra Nova Bay polynya was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite on October 16, 2007. Sea ice sits over the Ross Sea like a cracked and crumbling windshield. Blue-tinged glaciers flow down from the Trans-Antarctic Mountains. Although glaciers can appear blue because of melt water, they can also get that tint when the wind scours and polishes the ice surface. Given the strength of the katabatic winds along this part of the Antarctic coast, it is likely that the blue color of these glaciers is a result of their having been swept clean of snow. The large image has a spatial resolution (level of detail) of 250 meters per pixel.

    occasionally as far east as Honker and Grizzly bays; 3) estuarine ostracods and benthic foraminifers that lived within the bay are present outside the bay on the San Francisco bar and along the coast; 4) freshwater gastropods, ostracods, and thecamoebians from rivers feeding the bay are present in the middle of central bay and other subembayments of San Francisco Bay; 5) marsh benthic foraminifers that lived along the margins of the bay are also present in the middle of all of the subembayments; and 6) welding slag and glass microspheres are found far from their presumed origin of docks or roads. The distribution of constituents found in this study is consistent with the interpretation that sediment is transported from the delta to all regions of the bay and through the Golden Gate into the offshore. The reverse is also true, that sediment is carried from the marine realm into San Francisco Bay and reaches as far as the extreme end of south bay and nearly to the delta in north bay. Channels in north, central, and south bays, as well as the Golden Gate, are conduits for sediment movement and typically are sites where scouring occurs. The primary sites of deposition in the San Francisco Bay coastal system are in Honker, Grizzly, and Richardson bays, along the margins of Suisun, San Pablo and south bays, and in eastern central bay.

    Remote measurements of a number of surface or near surface parameters for baseline definition and specialized studies, remote measurements of episodic events, and remote measurements of the Bay lithosphere are considered in terms of characterizing and understanding the ecology of the Chesapeake Bay. Geologic processes and features best suited for information enhancement by remote sensing methods are identified. These include: (1) rates of sedimentation in the Bay; (2) rates of erosion of Bay shorelines; (3) spatial distribution and geometry of aquifers; (4) mapping of Karst terrain (sinkholes); and (5) mapping of fracture patterns. Recommendations for studying problem areas identified are given.

  19. Polychlorinated biphenyls (PCBs) in San Francisco Bay.

    PubMed

    Davis, J A; Hetzel, F; Oram, J J; McKee, L J

    2007-09-01

    San Francisco Bay is facing a legacy of polychlorinated biphenyls (PCBs) spread widely across the land surface of the watershed, mixed deep into the sediment of the Bay, and contaminating the Bay food web to a degree that poses health risks to humans and wildlife. In response to this persistent problem, water quality managers are establishing a PCB total maximum daily load (TMDL) and implementation plan to accelerate the recovery of the Bay from decades of PCB contamination. This article provides a review of progress made over the past 15 years in managing PCBs and understanding their sources, pathways, fate, and effects in the Bay, and highlights remaining information needs that should be addressed in the next 10 years. The phaseout of PCBs during the 1970s and the 1979 federal ban on sale and production led to gradual declines from the 1970s to the present. However, 25 years after the ban, PCB concentrations in some Bay sport fish today are still more than ten times higher than the threshold of concern for human health. Without further management action it appears that the general recovery of the Bay from PCB contamination will take many more decades. PCB concentrations in sport fish were, along with mercury, a primary cause of a consumption advisory for the Bay and the consequent classification of the Bay as an impaired water body. Several sources of information indicate that PCB concentrations in the Bay may also be high enough to adversely affect wildlife, including rare and endangered species. The greater than 90% reduction in food web contamination needed to meet the targets for protection of human health would likely also generally eliminate risks to wildlife. PCB contamination in the Bay is primarily associated with industrial areas along the shoreline and in local watersheds. Strong spatial gradients in PCB concentrations persist decades after the release of these chemicals to Bay Area waterways. Through the TMDL process, attention is being more sharply

    2009-02-01

    Multimedia fingerprinting (robust hashing) as a content identification technology is emerging as an effective tool for preventing unauthorized distribution of commercial content through user generated content (UGC) sites. Research in the field has mainly considered content types with slow distribution cycles, e.g. feature films, for which reference fingerprint ingestion and database indexing can be performed offline. As a result, research focus has been on improving the robustness and search speed. Live events, such as live sports broadcasts, impose new challenges on a fingerprinting system. For instance, highlights from a soccer match are often available-and viewed-on UGC sites well before the end of the match. In this scenario, the fingerprinting system should be able to ingest and index live content online and offer continuous search capability, where new material is identifiable within minutes of broadcast. In this paper, we concentrate on algorithmic and architectural challenges we faced when developing a video fingerprinting solution for live events. In particular, we discuss how to effectively utilize fast sorting algorithms and a master-slave architecture for fast and continuous ingestion of live broadcasts.

    2016-01-01

    To understand the positives and negatives of online dating according to the lived experience of older women, telephone interviews were conducted with 45 women ages 50+ who date online. Interviews were audio recorded, transcribed verbatim, and thematically team coded. The opportunity to expand one's social network for both friendships and romantic partners, the ability to control dating risks and pace of relationship formation, and knowing more about one's partner were significant reported benefits of online dating. Dating online also includes unique risks, such as pervasive lying, attempted financial exploitation in the form of scammers, and unwanted electronic sexual aggression.

  4. Long-term isolation and local adaptation in Palau's Nikko Bay help corals thrive in acidic waters

    NASA Astrophysics Data System (ADS)

    Golbuu, Yimnang; Gouezo, Marine; Kurihara, Haruko; Rehm, Lincoln; Wolanski, Eric

    2016-09-01

    The reefs in Palau's Nikko Bay live in seawater with low pH that is similar to conditions predicted for 2100 because of ocean acidification. Nevertheless, the reefs at Nikko Bay have high coral cover and high diversity. We hypothesize that the low-pH environment in Nikko Bay is caused by low flushing rates, which causes long-term isolation and local adaptation. To test this hypothesis, we modeled the water circulation in and around Nikko Bay. Model results show that average residence time is 71 d, which is ten times the residence time on fore-reef habitats. The long residence time restricts the exchange of coral larvae in the bay with adjacent reefs, allowing persistent selection for tolerant traits and local adaptation. The corals in Nikko Bay are also more susceptible to local pollution because the waters are poorly flushed. Therefore, local management must focus on minimizing human impacts such as dredging, overfishing and pollution in the bay, which would compromise the condition of the corals that have already adapted to low-pH conditions.

    2013-01-01

    International Space Station Live! (ISSLive!) is a Web application that uses a proprietary commercial technology called Lightstreamer to push data across the Internet using the standard http port (port 80). ISSLive! uses the push technology to display real-time telemetry and mission timeline data from the space station in any common Web browser or Internet- enabled mobile device. ISSLive! is designed to fill a unique niche in the education and outreach areas by providing access to real-time space station data without a physical presence in the mission control center. The technology conforms to Internet standards, supports the throughput needed for real-time space station data, and is flexible enough to work on a large number of Internet-enabled devices. ISSLive! consists of two custom components: (1) a series of data adapters that resides server-side in the mission control center at Johnson Space Center, and (2) a set of public html that renders the data pushed from the data adapters. A third component, the Lightstreamer server, is commercially available from a third party and acts as an intermediary between custom components (1) and (2). Lightstreamer also provides proprietary software libraries that are required to use the custom components. At the time of this reporting, this is the first usage of Web-based, push streaming technology in the aerospace industry.

  15. Online Friendship, Romance, and Sex: Properties and Associations of the Online Relationship Initiation Scale.

    PubMed

    Harris, Keith M; Aboujaoude, Elias

    2016-08-01

    Online relationships are increasingly central to many people's lives. As a result, there is a growing need to scientifically examine their psychosocial implications. This study developed and tested the Online Relationship Initiation Scale (ORIS) through classical and item response theory analyses to address this need. An anonymous online survey included 713 adults, aged 18-71 years. The ORIS was tested on psychometric properties and examined for associations with gender and several standardized psychosocial measures. Results demonstrated unidimensionality of nine items, strong factor loadings, and high internal consistency (α = 0.90, ωt = 0.94). All items captured significant information on the latent trait and none showed differential item functioning by sex, age group, or ethnicity. General linear modeling confirmed hypotheses that men were more likely than women to initiate online relationships. Online relationship initiation was not strongly associated with perceived social support, but was positively related to financial distress, and willingness to engage in infidelity or unprotected sex. The ORIS was negatively associated with age and satisfaction with life and showed modest interactions with ethnicity and hours online. This study provided empirical evidence for an interpersonal relationship initiation construct. The ORIS was shown to be a psychometrically sound instrument for evaluating online interpersonal behaviors and their associations with psychosocial and demographic factors. Such psychometrically sound instruments can be useful in exploring online interpersonal behaviors and their significance.

  1. MISR Views Delaware Bay, Chesapeake Bay, and the Appalachian Mountains

    NASA Technical Reports Server (NTRS)

    2000-01-01

    Multi-angle Imaging SpectroRadiometer (MISR) images of Delaware Bay, Chesapeake Bay, and the Appalachian Mountains acquired on March 24, 2000 during Terra orbit 1417. The large image on the right was taken by the MISR camera viewing straight down (nadir). The series of smaller images, from top to bottom, respectively, were taken by cameras viewing 70.5 degrees forward, 45.6 degrees forward, 45.6 degrees aftward, and 70.5 degrees aftward of nadir. These images cover the environs of Newark, Philadelphia, Baltimore, Washington, and Richmond. Differences in brightness, color, and contrast as a function of view angle are visible over both land and water. Scientists are using MISR data to monitor changes in clouds, Earth's surface, and pollution particles in the air, and to assess their impact on climate. North is toward the top.

    MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

    This report represents the culmination of a two-year, three-phase effort to determine the relative impact of DOD activities on the water quality and living resource of the Chesapeake Bay. Phase I defined the recent historical and present pollution potential of all 66 DOD installations in the Bay's drainage basin, and developed a preliminary screening procedure to categorize these installations according to existing or potential impacts on the Bay and its tributaries. Phase II developed and tested a detailed assessment methodology on six installations to define the character and extent of their impact on the Bay. Phase III applied this test-bed methodology to the remaining 31 installations identified in Phase I as needing more-detailed assessment, and summarizes impacts and program recommendations from an installation, regional, and Bay-wide perspective. This volume presents summary information from this analysis.

  16. Hurricane-induced Sediment Transport and Morphological Change in Jamaica Bay, New York

    NASA Astrophysics Data System (ADS)

    Hu, K.; Chen, Q. J.

    2016-02-01

    Jamaica Bay is located in Brooklyn and Queens, New York on the western end of the south shore of the Long Island land mass. It experienced a conversion of more than 60% of the vegetated salt-marsh islands to intertidal and subtidal mudflats. Hurricanes and nor'easters are among the important driving forces that reshape coastal landscape quickly and affect wetland sustainability. Wetland protection and restoration need a better understanding of hydrodynamics and sediment transport in this area, especially under extreme weather conditions. Hurricane Sandy, which made landfall along east coast on October 30, 2012, provides a critical opportunity for studying the impacts of hurricanes on sedimentation, erosion and morphological changes in Jamaica Bay and salt marsh islands. The Delft3D model suit was applied to model hydrodynamics and sediment transport in Jamaica Bay and salt marsh islands. Three domains were set up for nesting computation. The local domain covering the bay and salt marshes has a resolution of 10 m. The wave module was online coupled with the flow module. Vegetation effects were considered as a large number of rigid cylinders by a sub-module in Delft3D. Parameters in sediment transport and morphological change were carefully chosen and calibrated. Prior- and post-Sandy Surface Elevation Table (SET)/accretion data including mark horizon (short-term) and 137Cs and 210Pb (long-term) at salt marsh islands in Jamaica Bay were used for model validation. Model results indicate that waves played an important role in hurricane-induced morphological change in Jamaica Bay and wetlands. In addition, numerical experiments were carried out to investigate the impacts of hypothetic hurricanes. This study has been supported by the U.S. Geological Survey Hurricane Sandy Disaster Recovery Act Funds.

  17. Volatilization of mercury compounds by methylmercury-volatilizing bacteria in Minamata Bay sediment

    SciTech Connect

    Nakamura, K.; Sakata, T.; Nakahara, H.

    1988-11-01

    Minamata Bay has been heavily polluted by high mercury concentrations which gave rise for a long time to methylmercury poisoning, Minamata disease (Kutsuna 1968; Irukayama 1977). The mercury still exists in the sediments of the Bay. The population of mercury-resistant bacteria in the sediments of Minamata Bay is larger than that in the sediments of other marine environments. The mercury-resistant bacteria isolated from a marine environment have been found to transform organic and inorganic mercury compounds into mercury vapor. The mercury-resistance confirmed in various bacterial genera has been shown to be plasmid-mediated volatilization. However, there has been little definitive information on the volatilization of organic mercury by the bacteria living in the mercury-polluted environment. It is important to know what bacterial transformations of mercury have been taking place and how the mercury-resistant bacteria may be playing a role in the mercury cycle in the marine environment of Minamata Bay. The object of the present study is to clarify the characteristics of the methylmercury-volatilizing bacteria in the sediments of Minamata Bay and of the volatilization of various mercury compounds by these bacteria.

  18. Trapping of fine sediment in a semi-enclosed bay, Palau, Micronesia

    NASA Astrophysics Data System (ADS)

    Golbuu, Yimnang; Victor, Steven; Wolanski, Eric; Richmond, Robert H.

    2003-08-01

    Airai Bay, Palau, is a small (3 km 2), semi-enclosed, mangrove-fringed, meso-tidal, coral lagoon on the southeast coast of Palau. It drains a small catchment area (26 km 2) of highly erodible soils in an area with high annual rainfall (3.7 m). River floods are short-lived and the sediment load is very large, with suspended fine sediment concentration exceeding 1500 mg l -1. The resulting river plume is about 2 m thick. The brackish water residence time is about 7 days; during this period the plume remains a distinct surface feature even after river runoff has ceased. About 98% of the riverine fine sediment settles in Airai Bay, of which about 15-30% is deposited in the mangroves during river floods. This mud remains trapped in Airai Bay because the bay is protected from ocean swells and the tidal currents and locally generated wind waves are too small to resuspend the mud in quantity. The mud is smothering coral reefs, creating a phase shift from coral to fleshy algae dominance, and is even changing habitats by creating mud banks. The persistence of Airai Bay marine resources may not be possible without improved soil erosion control in the river catchment.

  19. Living Nanomachines

    NASA Astrophysics Data System (ADS)

    Carlier, M.-F.; Helfer, E.; Wade, R.; Haraux, F.

    The living cell is a kind of factory on the microscopic scale, in which an assembly of modular machines carries out, in a spatially and temporally coordinated way, a whole range of activities internal to the cell, including the synthesis of substances essential to its survival, intracellular traffic, waste disposal, and cell division, but also activities related to intercellular communication and exchanges with the outside world, i.e., the ability of the cell to change shape, to move within a tissue, or to organise its own defence against attack by pathogens, injury, and so on. These nanomachines are made up of macromolecular assemblies with varying degrees of complexity, forged by evolution, within which work is done as a result of changes in interactions between proteins, or between proteins and nucleic acids, or between proteins and membrane components. All these cell components measure a few nanometers across, so the mechanical activity of these nanomachines all happens on the nanometric scale. The directional nature of the work carried out by biological nanomachines is associated with a dissipation of energy. As examples of protein assemblies, one could mention the proteasome, which is responsible for the degradation of proteins, and linear molecular motors such as actomyosin, responsible for muscle contraction, the dynein-microtubule system, responsible for flagellar motility, and the kinesin-microtubule system, responsible for transport of vesicles, which transform chemical energy into motion. Nucleic acid-protein assemblies include the ribosome, responsible for synthesising proteins, polymerases, helicases, elongation factors, and the machinery of DNA replication and repair; the mitotic spindle is an integrated system involving several of these activities which drive chromosome segregation. The machinery coupling membranes and proteins includes systems involved in the energy metabolism, such as the ATP synthase rotary motor, signalling cascades, endocytosis

  20. Recruiting participants for research from online communities.

    PubMed

    Mendelson, Cindy

    2007-01-01

    Increasing numbers of people use the Internet for information and support about health and illness experiences. Likewise, researchers are increasingly turning to Internet communities as recruitment sites for research participants. Based on the use of online recruitment for a study of women living with lupus, the challenges and strategies associated with this method are discussed. How participants were obtained through posts on Web sites, the role of gatekeepers in accessing online communities, issues associated with list lurkers and posters, and challenges to authenticity when working with a sample recruited from this environment are covered, as are strategies for addressing identified problems.
