    Full Text Available One of the most important aspects in deciding to trade online, alone, without the help of a broker, is the portfolio profitability. In this study, using the personal experience, survey data and secondary sources, we identify some factors that may influence the gain and the loss of investors which trade online. Our study contradicts other results from literature that claim that the transition from assisted to online trading is a big drawback in terms of portfolio profitability. By analyzing the performance of the portfolio when passing from assisted to online trading, we observe that half of the investors achieved identical profitability. We also observed that the efficiency of the portfolios belonging to the online investors that were assisted in the past by a broker for a short period, is lower compared to the ones assisted (in the past for a longer period.

    2008-01-01

    During the last six years, from 2003-2008, Japan has been struck by three significant and damaging earthquakes: The most recent M6.6 Niigata Chuetsu Oki earthquake of July 16, 2007 off the coast of Kashiwazaki City, Japan; The M6.6 Niigata Chuetsu earthquake of October 23, 2004, located in Niigata Prefecture in the central Uonuma Hills; and the M8.0 Tokachi Oki Earthquake of September 26, 2003 effecting southeastern Hokkaido Prefecture. These earthquakes stand out among many in a very active period of seismicity in Japan. Within the upper 100 km of the crust during this period, Japan experienced 472 earthquakes of magnitude 6, or greater. Both Niigata events affected the south-central region of Tohoku Japan, and the Tokachi-Oki earthquake affected a broad region of the continental shelf and slope southeast of the Island of Hokkaido. This report is synthesized from the work of scores of Japanese and US researchers who led and participated in post-earthquake reconnaissance of these earthquakes: their noteworthy and valuable contributions are listed in an extended acknowledgements section at the end of the paper. During the Niigata Chuetsu Oki event of 2007, damage to the Kashiwazaki-Kariwa nuclear power plant, structures, infrastructure, and ground were primarily the product of two factors: (1) high intensity motions from this moderate-sized shallow event, and (2) soft, poor performing, or liquefiable soils in the coastal region of southwestern Niigata Prefecture. Structural and geotechnical damage along the slopes of dunes was ubiquitous in the Kashiwazaki-Kariwa region. The 2004 Niigata Chuetsu Earthquake was the most significant to affect Japan since the 1995 Kobe earthquake. Forty people were killed, almost 3,000 were injured, and many hundreds of landslides destroyed entire upland villages. Landslides were of all types; some dammed streams, temporarily creating lakes threatening to overtop their new embankments and cause flash floods and mudslides. The numerous

Coalition forces had higher Woman and Child DWIs than Anti-Coalition forces, with no evidence of decrease over 2003-2008, for all weapons combined and for small arms gunfire, specifically. CONCLUSIONS: Most Iraqi civilian violent deaths during 2003-2008 of the Iraq war were inflicted by Unknown perpetrators, primarily through extrajudicial executions that disproportionately increased in regions with greater numbers of violent deaths. Unknown perpetrators using suicide bombs, vehicle bombs, and mortars had highly lethal and indiscriminate effects on the Iraqi civilians they targeted. Deaths caused by Coalition forces of Iraqi civilians, women, and children peaked during the invasion period, with relatively indiscriminate effects from aerial weapons.

    Objective: Road traffic crashes (RTCs) are considered to be the second highest cause of mortality in Iran. The purpose of this study was to describe the morbidity and mortality of RTC during 2003-2008.Methods: Data were got from national health sources of Iran. These data included population, the number of RTCs,consequent fatalities, cause and place of death from 2003 to 2008.Results: RTC incidence rate increased from 868.5 per 100 000 population in the year 2003 to 1 643.6 in 2008. A total of 2 565 deaths from RTC were recorded in Yazd from 2003 to 2008. RTC mortality rate increased from 46.1 per 100 000 population in 2003 to 46.9 in 2006, then declined to 38.8 in 2008. During this time period, overall traffic injury incidence per 100 000 population increased from 368.8 in 2003 to 647.9 in 2006, then declined to 527.9 in 2008. Head injuries were the most common cause of road traffic-related mortality from 2003 to 2008. Following road traffic accidents, most of the deaths occurred before arriving hospital.Conclusions: Road traffic crash-related mortality and morbidity in Yazd in the recent six years are increased, but decreased in the last two years. This decline is most probably the result of a variety of interventions, including laws,police enforcement, improvements in traffic and transport,health care resources and media and public education.

    We present glacier thickness changes over the entire Pamir-Karakoram-Himalaya arc based on ICESat satellite altimetry data for 2003-2008. We highlight the importance of C-band penetration for studies based on the SRTM elevation model. This penetration seems to be of potentially larger magnitude and variability than previously assumed. The most negative rate of region-wide glacier elevation change (mass-gain anomaly rather than its centre. For the Ganges, Indus and Brahmaputra basins, the glacier mass change reaches -24 ± 2 Gt yr-1, about 10% of the current glacier contribution to sea-level rise. For selected catchments, we estimate glacier imbalance contributions to river run-off from a few percent to greater than 10%.

    Exposure to Bisphenol A (BPA) is ubiquitous and includes dietary and environmental pathways. BPA is rapidly glucuronidated in the body, and both BPA and its conjugates can be readily measured in urine. To investigate the contribution of canned food and beverages, known sources of BPA contamination, to BPA biomarkers of exposure using dietary and urinary BPA concentration information in a representative sample of the U.S. We evaluated 7669 NHANES 2003-2008 participants 6 years and older with 24-h dietary recall information and urinary BPA concentrations available. Using linear regression models, we evaluated the associations between recent canned food and beverage consumption and urinary BPA concentrations, adjusting for potential confounders. We found 9% of our participants consumed one canned food in the past 24h and 2% consumed two or more canned foods. The consumption of one canned food vs. none was associated with 24% (95% CI 1.11, 1.38) higher urinary BPA concentrations. The consumption of two or more canned foods vs. none was associated with 54% (95% CI 1.27, 1.88) higher urinary BPA concentrations. The consumption of one or more of some specific types of canned foods vs. none were associated with higher urinary BPA concentrations: 41% (95% CI 1.23, 1.63) higher BPA for vegetable and fruit, 70% (95% CI 1.18, 2.44) higher for canned pasta, and 229% (95% CI 1.22, 4.30) higher for canned soup. Canned beverages were not associated with urinary BPA concentrations. Canned food, including some specific types such as canned vegetable and fruit, canned pasta, and canned soup were associated with higher levels of urinary BPA concentrations.

    Full Text Available An association between pneumococcal serotypes and mortality has been suggested. We aimed to investigate this among individuals aged ≥15 years with invasive pneumococcal disease (IPD in South Africa.IPD cases were identified through national laboratory-based surveillance at 25 sites, pre-pneumococcal conjugate vaccine (PCV introduction, from 2003-2008. We assessed the association between the 20 commonest serotypes and in-hospital mortality using logistic regression with serotype 4 (the third commonest serotype with intermediate case-fatality ratio (CFR as referent.Among 3953 IPD cases, CFR was 55% (641/1166 for meningitis and 23% (576/2484 for bacteremia (p<0.001. Serotype 19F had the highest CFR (48%, 100/207, followed by serotype 23F (39%, 99/252 and serotype 1 (38%, 246/651. On multivariable analysis, factors independently associated with mortality included serotype 1 (OR 1.9, 95%CI 1.1-3.5 and 19F (OR 2.9, 95%CI 1.4-6.1 vs. serotype 4; increasing age (25-44 years, OR 1.8, 95%CI 1.0-3.0; 45-64 years, OR 3.6, 95%CI 2.0-6.4; ≥65 years, OR 5.2, 95%CI 1.9-14.1; vs. 15-24 years; meningitis (OR 4.1, 95%CI 3.0-5.6 vs. bacteremic pneumonia; and HIV infection (OR1.7, 95%CI 1.0-2.8. On stratified multivariate analysis, serotype 19F was associated with increased mortality amongst bacteremic pneumococcal pneumonia cases, while no serotype was associated with increased mortality in meningitis cases.Mortality was increased in HIV-infected individuals, which may be reduced by increased antiretroviral therapy availability. Serotypes associated with increased mortality are included in the 10-and-13-valent PCV and may become less common in adults due to indirect effects following routine infant immunization.

    Full Text Available For adults with disabilities who are experiencing homelessness, chances of being approved for Social Security disability benefits are very low without assistance. Assisting with the SSI/SSDI application process can be challenging for case managers who lack capacity and expertise. Training caseworkers to document disability and submit complete, high-quality applications using the SSI/SSDI Outreach, Access and Recovery (SOAR model improves efficiency and outcomes. Nationally, 65% of applications using the SOAR model are approved, with decisions received in an average of 81 days in 2015. The SOAR Online Course was created to expand training opportunities for individuals to learn how to effectively assist with SSI/SSDI applications for individuals experiencing or at risk for homelessness. From October 1, 2014 to September 30, 2015, 1049 individuals from 49 states, Washington, D.C., and Puerto Rico successfully completed the SOAR online course. The course is a unique public health training model, in that it incorporates a realistic and multimodal practice SSI/SSDI application with comprehensive feedback provided by experts. Local SOAR leaders around the county are trained to facilitate and guide groups through the course. This study evaluated data on online course usage, user experience, and the translation from learning to practice for online course trainees. We found that successful course completions were most concentrated in areas that had local SOAR Leaders, trainees through the online course had higher data entry rates about case outcomes in the SOAR Online Application Tracking (OAT system, and that trainees reported a high satisfaction rate with the course and comprehensive feedback. The evaluation found that key success factors for online training models include the integration of a practice case component (or other generative learning activity, support from local facilitators, and feedback and technical assistance for trainees.

    Internet commerce experiences a rising complexity: Not only more and more products become available online but also the amount of information available on a single product has been constantly increasing. Thanks to the Web 2.0 development it is, in the meantime, quite common to involve customers in the creation of product description and extraction of additional product information by offering customers feedback forms and product review sites, users' weblogs and other social web services. To face this situation, one of the main tasks in a future internet will be to aggregate, sort and evaluate this huge amount of information to aid the customers in choosing the "perfect" product for their needs.

    2004-01-01

    Full Text Available This paper outlines the architecture for an online assessment management system implemented at the University of Southern Queensland. The system assists teams of academics in the management and marking of electronically submitted student assignments in large-scale classes. The system designed to provide a flexible yet structured method for providing feedback to students also offers semi-automatic file handling and grade recording. The system, Classmate, allows a team of markers to access and mark student assignments through a web interface designed to parallel paper-based marking systems. An online authoring tool replaces the red pen on paper analogy. A pilot study conducted on the use of Classmate has found the system to be of use in providing students with consistent feedback, allowing traditional assignment interactions and reducing trivial and repetitive assignment marking tasks.

    Kenneth Lee

    Full Text Available BACKGROUND: Health information on the Internet is ubiquitous, and its use by health consumers prevalent. Finding and understanding relevant online health information, and determining content reliability, pose real challenges for many health consumers. PURPOSE: To identify the types of interventions that have been implemented to assist health consumers to find reliable online health information, and where possible, describe and compare the types of outcomes studied. DATA SOURCES: PubMed, PsycINFO, CINAHL Plus and Cochrane Library databases; WorldCat and Scirus 'gray literature' search engines; and manual review of reference lists of selected publications. STUDY SELECTION: Publications were selected by firstly screening title, abstract, and then full text. DATA EXTRACTION: Seven publications met the inclusion criteria, and were summarized in a data extraction form. The form incorporated the PICOS (Population Intervention Comparators Outcomes and Study Design Model. Two eligible gray literature papers were also reported. DATA SYNTHESIS: Relevant data from included studies were tabulated to enable descriptive comparison. A brief critique of each study was included in the tables. This review was unable to follow systematic review methods due to the paucity of research and humanistic interventions reported. LIMITATIONS: While extensive, the gray literature search may have had limited reach in some countries. The paucity of research on this topic limits conclusions that may be drawn. CONCLUSIONS: The few eligible studies predominantly adopted a didactic approach to assisting health consumers, whereby consumers were either taught how to find credible websites, or how to use the Internet. Common types of outcomes studied include knowledge and skills pertaining to Internet use and searching for reliable health information. These outcomes were predominantly self-assessed by participants. There is potential for further research to explore other avenues for

    2012-01-01

    Introduction Parafunctions (harmful habits) play a crucial role in the formation of temporo-mandibular joint (TMJ) dysfunction syndrome with disc displacement. Disorder symptoms in temporo-mandibular joints manifest themselves in the eye and ear but are usually not associated with the dysfunction of temporo-mandibular joints and that might lead to errors in diagnosis. The aim of the study was to examine the influence of missing teeth and parafunctions on the occurrence of ear and eye symptoms in patients treated in the Department of Prosthodontics of the Medical University of Lublin. Material and methods The patient group consisted of 753 women and 253 men aged 10 to 82 years who had been treated in the Department of Prosthodontics, Medical University of Lublin in the years 2003-2008 due to various symptoms associated with temporo-mandibular joint dysfunction. Results Eye (24.84%, n = 785) and ear (33.38%, n = 785) syndromes occur on average more often in patients with parafunctions than without them (15.98%, n = 219 and 23.29%, n = 219). However, only parafunctions involving tooth contact should be taken into consideration when diagnosing eye and ear syndromes. The data presented here show that the number of missing teeth does not have a significant influence on the frequency of occurrence of parafunctions. Parafunctions have become a very important factor in the diagnosis of diseases and pathological symptoms of eye and ear as the rate at which they occur is growing. Conclusions The kind of parafunction is very important. Only those involving tooth contact should be taken into consideration when diagnosing eye and ear syndromes. PMID:22457683

    Little is known about the relationship between food security status and predicted 10-year cardiovascular disease risk. The objective of this study was to examine the associations between food security status and cardiovascular disease risk factors and predicted 10-year risk in a national sample of US adults. A cross-sectional analysis using data from 10,455 adults aged 20 years or older from the National Health and Nutrition Examination Survey 2003-2008 was conducted. Four levels of food security status were defined by using 10 questions. Among all participants, 83.9% had full food security, 6.7% had marginal food security, 5.8% had low food security, and 3.6% had very low food security. After adjustment, mean hemoglobin A1c was 0.15% greater and mean concentration of C-reactive protein was 0.8 mg/L greater among participants with very low food security than among those with full food security. The adjusted mean concentration of cotinine among participants with very low food security was almost double that of participants with full food security (112.8 vs 62.0 ng/mL, P food security status and systolic blood pressure or concentrations of total cholesterol, high-density lipoprotein cholesterol, or non-high-density lipoprotein cholesterol were observed. Participants aged 30 to 59 years with very low food security were more likely to have a predicted 10-year cardiovascular disease risk greater than 20% than fully food secure participants (adjusted prevalence ratio, 2.38; 95% CI, 1.31-4.31). Adults aged 30 to 59 years with very low food security showed evidence of increased predicted 10-year cardiovascular disease risk.

    2014-12-01

    We would like to present a GIS-based 3D online decision assistance system for underground energy storage. Its aim is to support the local land use planning authorities through pre-selection of possible sites for thermal, electrical and substantial underground energy storages. Since the extension of renewable energies has become legal requirement in Germany, the underground storing of superfluously produced green energy (such as during a heavy wind event) in the form of compressed air, gas or heated water has become increasingly important. However, the selection of suitable sites is a complex task. The assistance system uses data of geological features such as rock layers, salt caverns and faults enriched with attribute data such as rock porosity and permeability. This information is combined with surface data of the existing energy infrastructure, such as locations of wind and biogas stations, power line arrangement and cable capacity, and energy distribution stations. Furthermore, legal obligations such as protected areas on the surface and current underground mining permissions are used for the decision finding process. Not only the current situation but also prospective scenarios, such as expected growth in produced amount of energy are incorporated in the system. The decision process is carried out via the 'Analytic Hierarchy Process' (AHP) methodology of the 'Multi Object Decision Making' (MODM) approach. While the process itself is completely automated, the user has full control of the weighting of the different factors via the web interface. The system is implemented as an online 3D server GIS environment, with no software needed to be installed on the user side. The results are visualized as interactive 3d graphics. The implementation of the assistance system is based exclusively on free and open source software, and utilizes the 'Python' programming language in combination with current web technologies, such as 'HTML5', 'CSS3' and 'JavaScript'. It is

    2017-08-29

    Completion of Advance Directives (ADs), being financial and healthcare proxy or instructional documents, is relatively uncommon in Australia. Efforts to increase completion rates include online education and prompting which past literature suggests may be effective. The aim of this randomized controlled trial was to assess computer-based online AD information and email prompting for facilitating completion of ADs by Australian Baby Boomers (b.1946-1965) as well as factors which may impede or assist completion of these documents by this generation when using the online environment. Two hundred eighty-two men and women aged 49-68 years at the time of the trial were randomly assigned to one of 3 intervention groups: education module only; email prompt only; email prompt and education module; and a control group with no education module and no email prompt. The randomized controlled trial was undertaken in participants' location of choice. Randomization and allocation to trial group were carried out by a central computer system. The primary analysis was based on a final total of 189 participants who completed the trial (n = 52 education module only; n = 44 email prompt only; n = 46 email prompt and education module; and n = 47 control). The primary outcome was the number of individuals in any group completing any of the 4 legal ADs in South Australia within 12 months or less from entry into the trial. Frequency analysis was conducted on secondary outcomes such as reasons for non-completion. Mean follow-up post-intervention at 12 months showed that 7% of overall participants completed one or more of the 4 legal ADs but without significant difference between groups (delta = 1%, p = .48 Prompt/Non-Prompt groups, delta = 5%, p = .44 education/non-education groups). Reasons offered for non-completion were too busy (26%) and/or it wasn't the right time (21%). Our results suggest that neither email prompting nor provision of additional educational material

    Introduction: Benefits from mental health early interventions may not be sustained over time, and longer-term intervention programs may be required to maintain early clinical gains. However, due to the high intensity of face-to-face early intervention treatments, this may not be feasible. Adjunctive internet-based interventions specifically designed for youth may provide a cost-effective and engaging alternative to prevent loss of intervention benefits. However, until now online interventions have relied on human moderators to deliver therapeutic content. More sophisticated models responsive to user data are critical to inform tailored online therapy. Thus, integration of user experience with a sophisticated and cutting-edge technology to deliver content is necessary to redefine online interventions in youth mental health. This paper discusses the development of the moderated online social therapy (MOST) web application, which provides an interactive social media-based platform for recovery in mental health. We provide an overview of the system's main features and discus our current work regarding the incorporation of advanced computational and artificial intelligence methods to enhance user engagement and improve the discovery and delivery of therapy content. Methods: Our case study is the ongoing Horyzons site (5-year randomized controlled trial for youth recovering from early psychosis), which is powered by MOST. We outline the motivation underlying the project and the web application's foundational features and interface. We discuss system innovations, including the incorporation of pertinent usage patterns as well as identifying certain limitations of the system. This leads to our current motivations and focus on using computational and artificial intelligence methods to enhance user engagement, and to further improve the system with novel mechanisms for the delivery of therapy content to users.

    Asthma, diabetes, and high blood pressure are common maternal conditions that can impact birth outcomes. Data from hospital discharges in Hawai'i were analyzed for 107,034 singleton births from 2003-2008. Categories were determined using the International Statistical Classification of Diseases, ninth revision (ICD-9) from linked delivery records of mother and infant. Prevalence estimates of asthma (ICD-9: 493), diabetes (ICD-9: 250,648.0, 648.8), high blood pressure (ICD-9: 401-405,642) as coded on the delivery record, low birth weight (high birth weight (>4500 grams), Cesarean delivery, and median hospital charges were calculated. Median regression analysis assessed total hospital charges adjusting for maternal age, maternal race, insurance, and Cesarean delivery. Maternal asthma was present in 4.3% (95% confidence interval=4.1-4.4%), maternal diabetes was present in 7.7% (95% CI=7.6-7.9%), and maternal high blood pressure was present in 9.2% (95% CI=9.0-9.3%) of births. In the adjusted median regression analysis, mothers with asthma had $999 (95% CI: $886 to $1,112) higher hospital charges compared to those without; mothers with diabetes had $743 (95% CI: $636 to $850) higher charges compared to those without; and mothers with high blood pressure had $2,314 (95% CI: $2,194 to $2,434) higher charges compared to those without. Asthma, diabetes, and high blood pressure are associated with higher hospital delivery charges and low birth weight. Diabetes and high blood pressure were also associated with Cesarean delivery. An increased awareness of the impact of these conditions on both adverse birth outcomes and the development of chronic disease is needed.

    Directory of Open Access Journals (Sweden)

    Janine Hacker

    2017-03-01

    Full Text Available One of the serious concerns in healthcare in this 21st century is obesity. While the causes of obesity are multifaceted, social networks have been identified as one of the most important dimensions of people's social environment that may influence the adoption of many behaviours, including health-promoting behaviours. In this article, we examine the possibility of harnessing the appeal of online social networks to address the obesity epidemic currently plaguing society. Specifically, a design science research methodology is adopted to design, implement and test the Health 2.0 application called “Calorie Cruncher”. The application is designed specifically to explore the influence of online social networks on individual’s health-related behaviour. In this regard, pilot data collected based on qualitative interviews indicate that online social networks may influence health-related behaviours in several ways. Firstly, they can influence people’s norms and value system that have an impact on their health-related behaviours. Secondly, social control and pressure of social connections may also shape health-related behaviours, and operate implicitly when people make food selection decisions. Thirdly, social relationships may provide emotional support. Our study has implications for research and practice. From a theoretical perspective, the article inductively identifies three factors that influence specific types of health outcomes in the context of obesity. From a practical perspective, the study underscores the benefits of adopting a design science methodology to design and implement a technology solution for a healthcare issue as well as the key role for online social media to assist with health and wellness management and maintenance.

    This column examines the experience, over three years, of a librarian embedded in an online Epidemiology and Evidence-based Medicine course, which is a requirement for students pursuing a Master of Science in Physician Assistant Studies at Pace University. Student learning outcomes were determined, a video lecture was created, and student learning was assessed via a five-point Blackboard test during year one. For years two and three, the course instructor asked the librarian to be responsible for two weeks of course instruction and a total of 15 out of 100 possible points for the course. This gave the librarian flexibility to measure additional outcomes and gather more in-depth assessment data. The librarian then used the assessment data to target areas for improvement in the lessons and Blackboard tests. Revisions made by the librarian positively affected student achievement of learning outcomes, as measured by the assessment conducted the subsequent semester. Plans for further changes are also discussed.

    An evaporation/condensation flow cell was developed and interfaced with the matrix-assisted laser desorption/ionization (MALDI) time-of-flight mass spectrometer for on-line bioaerosol detection and characterization, which allows matrix addition by condensation onto the laboratory-generated bioaerosol particles. The final coated particle exiting from the condenser is then introduced into the aerodynamic particle sizer spectrometer or home-built aerosol laser time-of-flight mass spectrometer, and its aerodynamic size directly effects on the matrix-to-analyte molar ratio, which is very important for MALDI technique. In order to observe the protonated analyte molecular ion, and then determine the classification of biological aerosols, the matrix-to-analyte molar ratio must be appropriate. Four experimental parameters, including the temperature of the heated reservoir, the initial particle size, its number concentration, and the matrix material, were tested experimentally to analyze their influences on the final particle size. This technique represents an on-line system of detection that has the potential to provide rapid and reliable identification of airborne biological aerosols.

    Malodorous hydrogen sulfide (H2S) gas often exists in the sewer system and associates with the problems of releasing the dangerous odor to the atmosphere and causing sewer pipe to be corroded. A simple method is in demand for real-time measuring H2S level in the sewer gas. In this paper, an innovated method based on dopant-assisted negative photoionization ion mobility spectrometry (DANP-IMS) with on-line semiconductor cooling inlet was put forward and successfully applied for the real-time measurement of H2S in sewer gas. The influence of moisture was effectively reduced via an on-line cooling method and a non-equilibrium dilution with drift gas. The limits of quantitation for the H2S in ≥60% relative humidity air could be obtained at ≤79.0ng L(-1) with linear ranges of 129-2064ng L(-1). The H2S concentration in a sewer manhole was successfully determined while its product ions were identified by an ion-mobility time-of-fight mass spectrometry. Finally, the correlation between sewer H2S concentration and the daily routines and habits of residents was investigated through hourly or real-time monitoring the variation of sewer H2S in manholes, indicating the power of this DANP-IMS method in assessing the H2S concentration in sewer system.

    We employed a polymeric material, poly(methyl methacrylate) (PMMA), for fabricating a microdevice and then implanted the chlorine (Cl)-containing solid-phase extraction (SPE) functionality into the PMMA chip to develop an innovative on-chip dipole-assisted SPE technique. Instead of the ion-ion interactions utilized in on-chip SPE techniques, the dipole-ion interactions between the highly electronegative C-Cl moieties in the channel interior and the positively charged metal ions were employed to facilitate the on-chip SPE procedures. Furthermore, to avoid labor-intensive manual manipulation, a programmable valve manifold was designed as an interface combining the dipole-assisted SPE microchip and inductively coupled plasma-mass spectrometry (ICP-MS) to achieve the fully automated operation. Under the optimized operation conditions for the established system, the detection limits for each analyte ion were obtained based on three times the standard deviation of seven measurements of the blank eluent solution. The limits ranged from 3.48 to 20.68 ng L(-1), suggesting that this technique appears uniquely suited for determining the levels of heavy metal ions in natural water. Indeed, a series of validation procedures demonstrated that the developed method could be satisfactorily applied to the determination of trace heavy metals in natural water. Remarkably, the developed device was durable enough to be reused more than 160 times without any loss in its analytical performance. To the best of our knowledge, this is the first study reporting on the combination of a dipole-assisted SPE microchip and elemental analysis instrument for the online determination of trace heavy metal ions.

    A rapid technique based on dynamic microwave-assisted extraction coupled with on-line solid-phase extraction of high-performance liquid chromatography (DMAE-SPE-HPLC) has been developed. A TM{sub 010} microwave resonance cavity built in the laboratory was applied to concentrate the microwave energy. The sample placed in the zone of microwave irradiation was extracted with 95% acetonitrile (ACN) aqueous solution which was driven by a peristaltic pump at a flow rate of 1.0 mL min{sup -1}. The extraction can be completed in a recirculating system in 10 min. When a number of extraction cycles were completed, the extract (1 mL) was diluted on-line with water. Then the extract was loaded into an SPE column where the analytes were retained while the unretained matrix components were washed away. Subsequently, the analytes were automatically transferred from the SPE column to the analytical column and determined by UV detector at 238 nm. The technique was used for determination of organochlorine pesticides (OCPs) in grains, including wheat, rice, corn and bean. The limits of detection of OCPs are in the range of 19-37 ng g{sup -1}. The recoveries obtained by analyzing the four spiked grain samples are in the range of 86-105%, whereas the relative standard deviation (R.S.D.) values are <8.7% ranging from 1.2 to 8.7%. Our method was demonstrated to be fast, accurate, and precise. In addition, only small quantities of solvent and sample were required.

    An effective and solvent-less method for the rapid determination of four commonly detected parabens (methyl-, ethyl-, propyl- and butyl-) in human urine samples is described. This method employed ultrasound-assisted emulsification microextraction (USAEME) before identification and quantitation of the parabens via on-line acetylation gas chromatography-mass spectrometry (GC-MS). Urine samples were enzymatically de-conjugated with β-glucuronidase and then extracted by an optimal USAEME procedure for the measurement of total concentrations of target analytes. The optimal USAEME parameters for one mL of urine sample (containing 0.1-g of sodium chloride), according to the Box-Behnken design method, are thus described: extractant of 200-μL of ethyl acetate, and ultrasonication for 1.0min and centrifugation at 7000rpm (3min). The supernatant was collected and evaporated until dry. Then the residue was re-dissolved in methanol (100-μL), and the extract was subjected to on-line acetylation GC-MS analysis. The limits of quantitation (LOQs) were less than 0.06ng/mL. Precisions for both intra- and inter-day analysis were calculated, and were less than 8%. Mean extraction recovery (known as trueness) was between 83 and 101% on three concentration levels. In human urine, the total concentrations of the four selected parabens, according to preliminary results, range from 0.3 to 124.5ng/mL for male, and from 27.2 to 246.3ng/mL for female. Female urine samples showed higher concentrations for the target parabens, which may indicate higher exposure due to lifestyle. This method permits accurate and high-throughput analysis of parabens for epidemiological studies. Copyright © 2017 Elsevier B.V. All rights reserved.

    We present the first application of submicrometric magnetic nanoporous carbons (μMNPCs) as sorbents for automated solid-phase extraction (SPE). Small zeolitic imidazolate framework-67 crystals are obtained at room temperature and directly carbonized under an inert atmosphere to obtain submicrometric nanoporous carbons containing magnetic cobalt nanoparticles. The μMNPCs have a high contact area, high stability, and their preparation is simple and cost-effective. The prepared μMNPCs are exploited as sorbents in a microcolumn format in a sequential injection analysis (SIA) system with online spectrophotometric detection, which includes a specially designed three-dimensional (3D)-printed holder containing an automatically actuated electromagnet. The combined action of permanent magnets and an automatically actuated electromagnet enabled the movement of the solid bed of particles inside the microcolumn, preventing their aggregation, increasing the versatility of the system, and increasing the preconcentration efficiency. The method was optimized using a full factorial design and Doehlert Matrix. The developed system was applied to the determination of anionic surfactants, exploiting the retention of the ion-pairs formed with Methylene Blue on the μMNPC. Using sodium dodecyl sulfate as a model analyte, quantification was linear from 50 to 1000 μg L(-1), and the detection limit was equal to 17.5 μg L(-1), the coefficient of variation (n = 8; 100 μg L(-1)) was 2.7%, and the analysis throughput was 13 h(-1). The developed approach was applied to the determination of anionic surfactants in water samples (natural water, groundwater, and wastewater), yielding recoveries of 93% to 110% (95% confidence level).

    Haloacetic acids (HAAs) are by-products of the chlorination of drinking water containing natural organic matter and bromide. A simple and sensitive method has been developed for determination of ten HAAs in drinking water. The pressure-assisted electrokinetic injection (PAEKI), an on-line enrichment technique, was employed to introduce the sample into a capillary electrophoresis (CE)-electrospray ionization-tandem mass spectrometry system (ESI-MS/MS). HAAs were monitored in selected reaction monitoring mode. With 3 min of PAEKI time, the ten major HAAs (HAA10) in drinking water were enriched up to 20,000-fold into the capillary without compromising resolution. A simple solid phase clean-up method has been developed to eliminate the influence of ionic matrices from drinking water on PAEKI. Under conditions optimized for mass spectrometry, PAEKI and capillary electrophoresis, detection limits defined as three times ratio of signal to noise have been achieved in a range of 0.013-0.12 μg L(-1) for ten HAAs in water sample. The overall recoveries for all ten HAAs in drinking water samples were between 76 and 125%. Six HAAs including monochloro- (MCAA), dichloro- (DCAA), trichloro- (TCAA), monobromo- (MBAA), bromochloro- (BCAA), and bromodichloroacetic acids (BDCAA) were found in tap water samples collected.

    The involvement of persons with lived experiences of mental illness and service use is increasingly viewed as key to improving the relevance and utility of mental health research and service innovation. Guided by the principles of Community-Based Participatory Research we developed an online tool for assisted self-help in mental health. The resulting tool, PsyConnect, is ready for testing in two communities starting 2014. This case study reports from the design phase which entailed clarifying very basic questions: Who is the primary target group? What are the aims? What functions are priorities? Roles and responsibilities? What types of evidence can legitimize tool design decisions? Here we highlight the views of service users as a basis for discussing implications of user involvement for service design and research. PsyConnect has become a tool for those who expect to need assistance over long periods of time regardless of their specific condition(s). The aim is to support service users in gaining greater overview and control, legitimacy, and sense of continuity in relationships. It has a personalized "my control panel" which depicts status → process → goals. Functionality includes support for: mapping life domains; medication overview; crisis management; coping exercises; secure messaging; and social support. While the types of evidence that can legitimize design decisions are scattered and indirectly relevant, recent trends in recovery research will be used to guide further refinements. PsyConnect has undoubtedly become something other than it would have been without careful attention to the views of service users. The tool invites a proactive approach that is likely to challenge treatment cultures that are reactive, disorder-focused and consultation-based. Service user representatives will need to play central roles in training peers and clinicians in order to increase the likelihood of tool usage in line with intentions. Similarly, their influence on tool

    Processed foods are an integral part of American diets, but a comparison of the nutrient contribution of foods by level of processing with the recommendations of the Dietary Guidelines for Americans regarding nutrients to encourage or to reduce has not been documented. The mean reported daily dietary intakes of these nutrients and other components were examined among 25,351 participants ≥2 y of age in the 2003-2008 NHANES to determine the contribution of processed food to total intakes. Also examined was the percent contribution of each nutrient to the total reported daily nutrient intake for each of the 5 categories of food that were defined by the level of processing. All processing levels contributed to nutrient intakes, and none of the levels contributed solely to nutrients to be encouraged or solely to food components to be reduced. The processing level was a minor determinant of individual foods' nutrient contribution to the diet and, therefore, should not be a primary factor when selecting a balanced diet.

    Full Text Available Objective – To discover public library clients’ needs and preferences for modes of training on the use of the Internet and the libraries’ online resources and to apply these findings to improve training offered by public library staff.Design – Multiple exploratory case study.Setting – Two public libraries in New South Wales, Australia: a regional library (Mudgee Branch of the Mid-Western Regional Council Library Service and a metropolitan library (Marrickville Central Library.Subjects – A total of 24 public library clients. The participants were split evenly between the two libraries, with 12 from the Mudgee Branch and 12 from the Marrickville Central. The respondents were further subdivided into two groups based on age (35 to 44 years old and 65 or older and evenly distributed by sex within the groups.Methods – This study used naturalistic inquiry to frame the multiple exploratory case study of two public libraries. Ruthven used maximum variation sampling to guide the selection of participants. Library staff helped the researcher to identify possible participants at Marrickville, while the researcher advertised for participants at Mudgee Library and at an Internet/database course taught at the Mudgee Business Enterprise Centre. She used snowball sampling to find additional participants at both sites. Ruthven conducted semi-structured interviews with the participants, with questions covering their preferences, recommendations, and needs for online resource training. The data from the interviews and search logs were analyzed using inductive data analysis.Main Results – Participants preferred small group, face-to-face, formalized instruction for initial training on online resources. For further training, participants preferred individualized assistance and immediate support instead of formal classes. They noted a lack of training opportunities and a lack of help from library staff as sources of frustration when trying to learn to

Randomized controlled studies of at least three months' duration assessing at least two prostaglandin analogs in patients with primary open-angle glaucoma, ocular hypertension, or normal-tension glaucoma were included. The primary endpoint was mean IOP. Summary estimates were created using random-effects models. The Q Chi-square test was used to assess statistical heterogeneity.Results: Sixteen studies satisfied the inclusion criteria and were analyzed. On average, greater IOP-lowering was seen with bimatoprost relative to latanoprost (1 mmHg, P = 0.025 and travoprost (0.8 mmHg, P = 0.033 based on mean IOP after 12–26 weeks of treatment. No statistical difference was observed in IOP-lowering between latanoprost and travoprost (P = 0.841. Findings were similar to previously published meta-analyses of topical prostaglandin analogs.Conclusion: Systematic reviews relying on meta-analytic techniques to create summary statistics are considered to be the "gold standard" for synthesizing evidence to support clinical decision-making.

Thiomersal was quantitatively converted in the MW/UV process to Hg(II), with a yield of 97 ± 3%. This reaction was followed by the reduction of Hg(II) to Hg(0) performed in a knotted reaction coil with NaBH{sub 4} solution, and AFS detection in an Ar/H{sub 2} miniaturized flame. The method was linear in the 0.01–2 μg mL{sup −1} range, with a LOD of 0.003 μg mL{sup −1}. This method has been applied to the determination of thiomersal in ophthalmic solutions, with recoveries ranging between 97% and 101%. We found a mercury concentration in commercial ophthalmic solutions ranging between 7.5 and 59.0 μg mL{sup −1}.

    An automated fluidic instrument is described that rapidly determines the total (99)Tc content of aged nuclear waste samples, where the matrix is chemically and radiologically complex and the existing speciation of the (99)Tc is variable. The monitor links microwave-assisted sample preparation with an automated anion exchange column separation and detection using a flow-through solid scintillator detector. The sample preparation steps acidify the sample, decompose organics, and convert all Tc species to the pertechnetate anion. The column-based anion exchange procedure separates the pertechnetate from the complex sample matrix, so that radiometric detection can provide accurate measurement of (99)Tc. We developed a preprogrammed spike addition procedure to automatically determine matrix-matched calibration. The overall measurement efficiency that is determined simultaneously provides a self-diagnostic parameter for the radiochemical separation and overall instrument function. Continuous, automated operation was demonstrated over the course of 54 h, which resulted in the analysis of 215 samples plus 54 hly spike-addition samples, with consistent overall measurement efficiency for the operation of the monitor. A sample can be processed and measured automatically in just 12.5 min with a detection limit of 23.5 Bq/mL of (99)Tc in low activity waste (0.495 mL sample volume), with better than 10% RSD precision at concentrations above the quantification limit. This rapid automated analysis method was developed to support nuclear waste processing operations planned for the Hanford nuclear site.

    In this paper, four organic acids constituents of Plateau alfalfa roots have been identified and detected by a novel capillary electrophoresis (CE) strategy which combined chitosan (CS) trapping and cetyltrimethyl ammonium bromide (CTAB) assisted sample stacking. Under the optimized condition, organic acids, i.e., aconitic acid, gallic acid, citric acid and l-malic acid were concentrated and separated within 3 min. Validation parameters of this method (such as detection limits, linearity and precision) were also investigated and the limit of detection (LOD) was 2.41-53.9 ng mL(-1). Linearity was obtained over the magnitude range of 5-4000 ng mL(-1) approximately for different organic acids and 3×10(2)-1.5×10(4) folds enrichment was achieved. The method has been applied to the determination of organic acids in roots of normal grown Plateau alfalfa and stressing affected Plateau alfalfa. Satisfactory results and recoveries were obtained in the analysis without costly and complicated sample pretreatment.

    A high throughput, high-sensitivity procedure, involving simultaneous microwave-assisted extraction (MAS) and unsaponifiable extraction, followed by on-line liquid chromatography (LC)-gas chromatography (GC), has been optimised for rapid and efficient extraction and analytical determination of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) in cereal-based products of different composition. MAS has the advantage of eliminating fat before LC-GC analysis, allowing an increase in the amount of sample extract injected, and hence in sensitivity. The proposed method gave practically quantitative recoveries and good repeatability. Among the different cereal-based products analysed (dry semolina and egg pasta, bread, biscuits, and cakes), egg pasta packed in direct contact with recycled paperboard had on average the highest total MOSH level (15.9 mg kg(-1)), followed by cakes (10.4 mg kg(-1)) and bread (7.5 mg kg(-1)). About 50% of the pasta and bread samples and 20% of the biscuits and cake samples had detectable MOAH amounts. The highest concentrations were found in an egg pasta in direct contact with recycled paperboard (3.6 mg kg(-1)) and in a milk bread (3.6 mg kg(-1)).

    On-line ultrasound-assisted dispersive micro-solid-phase extraction (USA-DμSPE) has been developed for preconcentration and separation of trace amounts of Cd(II) ions in 0.5 mL of human biological samples. In a syringe with a nylon membrane, new synthetic bulky amino bimodal mesoporous silica nanoparticles (NH2-UVM7) were dispersed as a nanoadsorbent in 5 mL of diluted serum sample (1:10), and after ultrasonic shaking, the liquid phase was separated from the solid phase. At the optimized pH, the chemical and physical adsorption of cadmium ions occurred, respectively, based on complexation with amine groups of UVM7 (Cd:NH2-UVM7) and silica nanoparticles. The analyte was then back-extracted from the sorbent with nitric acid solution (0.2 M), and its concentration was determined by electrothermal atomic absorption spectrometry (ETAAS). Under the optimized conditions, the linear range, limit of detection (LOD), and preconcentration factor (PF) were obtained as 0.01-0.56 μg L(-1), 0.002 μg L(-1), and 25, respectively. The adsorption capacity of NH2-UVM7 was found to be 108.6 mg g(-1) of cadmium. The validation of the methodology was performed by the human standard reference material (HSRM).

    2011-01-01

    This chapter explores what makes online advertising different from traditional advertising channels. We argue that online advertising differs from traditional advertising channels in two important ways: measurability and targetability. Measurability is higher because the digital nature of online advertising means that responses to ads can be tracked relatively easily. Targetability is higher because data can be automatically tracked at an individual level, and it is relatively easy to show di...

  5. Housing Assistance

    Full Text Available In Australia, an increasing number of households face problems of access to suitable housing in the private market. In response, the Federal and State Governments share responsibility for providing housing assistance to these, mainly low-income, households. A broad range of policy instruments are used to provide and maintain housing assistance across all housing tenures, for example, assisting entry into homeownership, providing affordability assistance in the private rental market, and the provision of socially owned and managed housing options. Underlying each of these interventions is the premise that secure, affordable, and appropriate housing provides not only shelter but also a number of nonshelter benefits to individuals and their households. Although the nonshelter outcomes of housing are well acknowledged in Australia, the understanding of the nonshelter outcomes of housing assistance is less clear. This paper explores nonshelter outcomes of three of the major forms of housing assistance provided by Australian governments—low-income mortgage assistance, social housing, and private rent assistance. It is based upon analysis of a survey of 1,353 low-income recipients of housing assistance, and specifically measures the formulation of health and well-being, financial stress, and housing satisfaction outcomes across these three assistance types. We find clear evidence that health, finance, and housing satisfaction outcomes are associated with quite different factors for individuals in these three major housing assistance types.

    Institutions of higher education are now using Internet-based technology tools to conduct surveys for data collection. Research shows that the type and quality of responses one receives with online surveys are comparable with what one receives in paper-based surveys. Data collection can take place on Web-based surveys, e-mail-based surveys, and personal digital assistants/Smartphone devices. Web surveys can be subscription templates, software packages installed on one's own server, or created from scratch using Web programming development tools. All of these approaches have their advantages and disadvantages. The survey owner must make informed decisions as to the right technology to implement. The correct choice can save hours of work in sorting, organizing, and analyzing data.

  14. Experience of the Irish National Centre for hereditary haemorrhagic telangiectasia 2003-2008.

    LENUS (Irish Health Repository)

    Ni Bhuachalla, C F

    2012-01-31

    Hereditary haemorrhagic telangiectasia (HHT) is a group of autosomal dominant disorders of vascular structure. The Irish National Centre for HHT at the Mercy University Hospital, Cork, Ireland was founded in 2003. From 2003 to 2008, screening of 164 patients with contrast echocardiography, thoracic computerised tomography (CT) and cerebral magnetic resonance imaging (MRI) has identified 88 patients with definite HHT, 72 (82%) of whom had epistaxis, 70 (80%) had telangiectasia and 81 (92%) had a first-degree relative with HHT. We sought to describe the manifestations of HHT in an Irish population and to determine differences between internationally reported data. The HHT patient database was analysed to describe demographics, clinical manifestations and interventional procedures performed in all referred patients. Contrast echocardiography and\\/or CT were performed in 86 patients with definite HHT, identifying 27 patients (31%) with pulmonary arteriovenous malformations (pAVMs). Nineteen patients with single or multiple pAVMs had 28 embolisation procedures performed, with 1-6 pAVMs embolised per procedure. Cerebral MRI was performed in 78 (89%) patients and 2 (2.3%) had cerebral arteriovenous malformations (cAVMs). HHT prevalence is thought to be 1 in 2500-8000, suggesting that there are many undiagnosed cases in Irish patients. Internationally published data suggest a prevalence of 15-35% for pAVMs and 10-23% for cAVMs in patients with HHT. While the prevalence of pAVMs in our group is consistent with these data, the prevalence of cAVMs is considerably lower, suggesting that Irish patients with HHT may differ genotypically and phenotypically from those in other countries.

O tratamento predominante foi o cirúrgico, que demonstrou ser eficaz com recuperação satisfatória em 90% dos casos e menor possibilidade de recidiva, quando comparado ao trata,mento clínico. O tempo de recuperação predominante foi de 30-60 dias após a cirurgia, não existindo relação deste com a duração dos sinais clínicos.A retrospective study on atlantoaxial subluxation in dogs was done by reviewing the cases filed from 2003 to 2008 in the neurological records of the Veterinary Hospital of the Universidade Federal de Santa Maria, at Santa Maria, Rio Grande do Sul, Brazil. The following data were identified: Breed, sex, age, etiology, clinical signs, duration of clinical course, assessment of the therapy employed and its efficacy, response to treatment and relapse. Fourteen dogs were diagnosed as affected by atlantoaxial subluxation and the condition was more frequent in dogs under twenty-four month old years and of toy breeds, such as Poodle (35.7%, Pinscher (21.4% and Yorkshire terrier (21.4%. The main cause found for the instability was agenesis of the odontoid process. Clinical signs ranged from cranial cervical pain to non-ambulatory tetraparesis. The predominant treatment employed was surgical which demonstrated to be efficacious in 90% of the cases with minor risks of relapse when compared with clinical treatment. The predominant time of recovery was 30-60 days after surgery. No correlation was found between the duration of clinical signs before surgery and the time of recovery.

    Esophageal cancer is the sixth cause of death in the world, there was a lack of population-based information on the trend and incidence rate of esophagus cancer, so this study aimed to determine the incidence and pathological changes of esophagus cancer in Iran. In this study, data were extracted from annual cancer registry reports of Iranian ministry of health between 2003 and 2008. Standardized incidence rates were calculated using the world standard population, and incidence rate was calculated by age groups, sex, and histological type. Data on epidemiologic trend and histology were analyzed using Joinpoint software package. In this study, there were 18,177 recorded cases of esophagus cancer. Of all cases, 45.72% were females and 54.28% were males. Sex ratio was 1.19. The most common histological types related to squamous cell carcinoma NOS and adenocarcinoma NOS were 64.53% and 10.37%, respectively. The trend of annual changes of incidence rate significantly increased in both sexes. The annual percentage changes, the incidence rate was 7.9 (95% confidence interval [CI]: 3.3-12.6) for women and 9.6 (95% CI: 6.0-13.2) for men. The histology type of SCC, large cell, nonkeratinizing and SCC, keratinizing and SCC, NOS had a significant decreasing trend in total population (P trend of age-standardized incidence rate of esophagus cancer in Iran is rising. Hence, to prevent and control this cancer, it is necessary to investigate related risk factors and implement prevention programs in Iran.

    2013-11-01

    Renewed fieldwork from 2003 through 2008 at the Australopithecus anamensis type-site of Kanapoi, Kenya, yielded nine new fossils attributable to this species. These fossils all date to between 4.195 and 4.108 million years ago. Most were recovered from the lower fluvial sequence at the site, with one from the lacustrine sequence deltaic sands that overlie the lower fluvial deposits but are still below the Kanapoi Tuff. The new specimens include a partial edentulous mandible, partial maxillary dentition, two partial mandibular dentitions, and five isolated teeth. The new Kanapoi hominin fossils increase the sample known from the earliest Australopithecus, and provide new insights into morphology within this taxon. They support the distinctiveness of the early A. anamensis fossils relative to earlier hominins and to the later Australopithecus afarensis. The new fossils do not appreciably extend the range of observed variation in A. anamensis from Kanapoi, with the exception of some slightly larger molars, and a canine tooth root that is the largest in the hominin fossil record. All of the Kanapoi hominins share a distinctive morphology of the canine-premolar complex, typical early hominin low canine crowns but with mesiodistally longer honing teeth than seen in A. afarensis, and large, probably dimorphic, canine tooth roots. The new Kanapoi specimens support the observation that canine crown height, morphology, root size and dimorphism were not altered from a primitive ape-like condition as part of a single event in human evolution, and that there may have been an adaptive difference in canine function between A. anamensis and A. afarensis.

    Access to, and use of, dental health services in Brazil have improved since 2003. The increase of private health care plans and the implementation of the "Smiling Brazil" Program, the largest public oral health care program in the world, could have influenced this increase in access. However, we do not yet know if inequalities in the use of dental health services persist after the improvement in access. The aims of this study are to analyze socioeconomic differences for dental health service use between 2003 and 2008 in São Paulo and to examine changes in these associations since the implementation of the Smiling Brazil program in 2003. Data was obtained via two household health surveys (ISA-Capital 2003 and ISA-Capital 2008) which investigated living conditions, lifestyle, health status and use of health care services. Logistic regression was used to analyze associations between socioeconomic factors and dental services use. Additionally, trends from 2003 to 2008 regarding socioeconomic characteristics and dental health service use were explored. Overall, dental health service use increased between 2003 and 2008 and was at both time points more common among those who had higher income, better education, better housing conditions, private health care plans and were Caucasian. Inequalities in use of dental health care did not decrease over time. Among the reasons for not seeking dental care, not having teeth and financial difficulty were more common in lower socioeconomic groups, while thinking it was unnecessary was more common in higher socioeconomic groups. The Brazilian oral health policy is still in a period of expansion and seems to have contributed slightly to increased dental health service use, but has not influenced socioeconomic inequalities in the use of these services. Acquiring deeper knowledge about inequalities in dental health service use will contribute to better understanding of potential barriers to reducing them.

    In the last few decades, there has been a remarkable increase in the number of children and adolescents presenting with psychiatric complaints to the emergency department in the USA. In Europe, however, less is known about the paediatric psychiatric emergency population. This study provides a clinical and demographic profile of this population and its service use in a European context. From 2003 to 2008, we registered 989 paediatric psychiatric patients consulting the psychiatric emergency services (PES) of a large university hospital in Belgium. During this period the number of patients increased more than three-fold. Patients were predominantly female (57.3%) and adolescent (83.3%) and mostly referred for hostility and violence towards others (18.5%) and suicidal ideation (17.8%). For about 1/4 of the patients, PES was the first ever mental health treatment contact. PES could serve as a place for early detection and intervention and as an entry point to mental health services.

    A developed discipline of econophysics that has been introduced is exhibiting the application of mathematical tools that are usually applied to the physical models for the study of financial models. In this study, an analysis of the time series behavior of several blue chip and penny stock companies in Main Market of Bursa Malaysia has been performed. Generally, the basic quantity being used is the relative price changes or is called the stock price returns, contains daily-sampled data from the beginning of 2003 until the end of 2008, containing 1555 trading days recorded. The aim of this paper is to investigate the tail exponent in tails of the distribution for blue chip stocks and penny stocks financial returns in six years period. By using a standard regression method, it is found that the distribution performed double scaling on the log-log plot of the cumulative probability of the normalized returns. Thus we calculate α for a small scale return as well as large scale return. Based on the result obtained, it is found that the power-law behavior for the probability density functions of the stock price absolute returns P(z)˜z-α with values lying inside and outside the Lévy stable regime with values α>2. All the results were discussed in detail.

    of the Greenland ice sheet. Firn dynamics and surface densities are important factors that contribute to the mass change derived from remote-sensing altimetry. The volume change derived from ICESat data is corrected for changes in firn compaction over the observation period, vertical bedrock movement...... and an intercampaign elevation bias in the ICESat data. Subsequently, the corrected volume change is converted into mass change by the application of a simple surface density model, in which some of the ice dynamics are accounted for. The firn compaction and density models are driven by the HIRHAM5 regional climate...... altimetry data. Three different methods for deriving elevation changes from the ICESat altimetry dataset are used. This multi-method approach provides a method to assess the complexity of deriving elevation changes from this dataset. The altimetry alone can not provide an estimate of the mass balance...

    Rates of vertical HIV transmission between mother and child are low, allowing many HIV positive women to have children with near impunity. In this study, data from the Swiss Mother and Child HIV Cohort Study were used to describe maternal characteristics and their association with pregnancy outcomes in HIV positive women. HIV positive women were followed prospectively during their pregnancies and deliveries by anonymous questionnaires between January 2003 and October 2008. Adverse pregnancy outcomes included preterm delivery, preeclampsia and gestational diabetes mellitus. This study included 266 HIV positive women, of which 67 (25.2%) were first diagnosed with HIV during pregnancy. Thirty percent (n=80) of the women had pregnancy complications after 24 weeks of gestation. Preterm delivery was noted in 72 (27%) patients. Other complications included preeclampsia (n=7; 2.6%) and gestational diabetes (n=7; 2.6%). Older maternal age was the only risk factor associated with adverse pregnancy outcomes (adjusted odds ratio: 1.06, 95% confidence interval 1.01-1.12, P=0.02). HIV positive women, especially with advanced maternal age, have high-risk pregnancies and should be monitored as in an interdisciplinary setting. The preponderance of initial HIV diagnosis during pregnancy confirms the importance of HIV screening in pregnant women.

    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").

    Full Text Available [english] Practising veterinarians in Germany are obliged to take part in continuing education. Due to high expenses which are incurred while taking part in continuing education, such as replacement of personnel, travel costs, conference fees, etc., it is important that efforts toward achievement of learning objectives are maximized. Through the introduction of rapid e-learning techniques, several conferences have been digitised and made available via the internet including publication of CD-ROMs to give participants the possibility of repeated learning. The acceptability of this technique was tested via utilisation data and a survey of participants. It was found that 83.3% of lecturers provided their talks (i.e., a total of approximately 196 lectures for digital distribution. The website featuring the on-line lectures recorded an average of 22 visits per day during a 12-month period. The survey conducted on 82 participants showed a high level of acceptance toward the e-learning technique. In conclusion, there is evidence of a great demand for using new media in continuing education for practitioners of veterinary medicine.

  18. Holding Your Hand From a Distance: Online Mentoring and the Graduate Library and Information Science Student

    Directory of Open Access Journals (Sweden)

    Elizabeth A. Buchanan

    2005-07-01

    Full Text Available The emergence of online education in colleges and universities brings with it a variety of issues and concerns for the remote student. One such issue is online mentoring. This paper presents a study that examines perceptions of the impact and role of online mentoring by online graduate students in a Master of Library and Information Science program. The guiding research question asked “what impact does online mentoring have on the online student experience?” A survey using open and closed-ended response questions was administered. Findings indicate that the participants see the need for online mentors in at least two forms—peer mentors to assist with the “institutional maze” surrounding distance education programs, and secondly, professional mentors to assist with career planning and development. Institutions should thus consider a two-tiered mentor network to meet the needs of students at various points in their academic lives.

We show that well known fair division procedures like cut-and-choose and the Dubins-Spanier moving knife procedure can be adapted to apply to such online problems. We propose some desirable properties that online cake cutting procedures might possess like online forms of proportionality and envy-freeness, and identify which properties are in fact possessed by the different online cake procedures.

    2010-01-01

    Tests and final examination scores of three semesters of control students in a nursing foundation course were compared with tests and final examination scores of three semesters of participating students. Participating students were offered access to an asynchronous pretest online discussion activity with a faculty e-moderator. While the simplified Bloom's revised taxonomy assisted in creating appropriate preparatory test and final examination questions for pretest online discussion, Salmon's five-stage online method provided direction to the e-moderator on how to encourage students to achieve Bloom's higher-order thinking skills during the pretest online discussions. Statistical analysis showed the pretest online discussion activity had a generally positive impact on tests and final examination scores, when controlling for a number of possible confounding variables, including instructor, cumulative grade point average, age, and credit hours.

    2008-04-01

    Full Text Available The impact of ever-increasing numbers of online courses on the demographic composition of classes has meant that the notions of diversity, multiculturality and globalization are now key aspects of curriculum planning. With the internationalization and globalization of education, and faced with rising needs for an increasingly educated and more adequately trained workforce, universities are offering more flexible programs, assisted by new educational and communications technologies. Faced with this diversity of populations and needs, many instructors are becoming aware of the importance of addressing the notions of multiculturality and interculturality in the design of online however this raises many questions. For example, how do we integrate and address this multicultural dimension in a distance education course aimed at students who live in diverse cultural environments? How do the challenges of intercultural communication in an online environment affect online teaching and learning? What are the characteristics of an online course that is inclusive of all types of diversity, and what are the guiding principles for designing such courses? We will attempt to answer some of these questions by first exploring the concepts of culture and learning cultures. This will help us to characterize the impact on online learning of particular cultural dimensions. We will then present and discuss different online instructional design models that are culturally inclusive, and conclude with the description of a mediated instructional training module on the management of the cultural dimension of online teaching and learning. This module is mainly addressed to teachers and designers of online courses.

    Cho, Chang-Hoan; Kang, Jaewon; Cheon, Hongsik John

    2006-06-01

    This study was designed to understand which factors influence consumer hesitation or delay in online product purchases. The study examined four groups of variables (i.e., consumer characteristics, contextual factors perceived uncertainty factors, and medium/channel innovation factors) that predict three types of online shopping hesitation (i.e., overall hesitation, shopping cart abandonment, and hesitation at the final payment stage). We found that different sets of delay factors are related to different aspects of online shopping hesitation. The study concludes with suggestion for various delay-reduction devices to help consumers close their online decision hesitation.

    Janowicz, Philip A.

    This is a comprehensive study of the many facets of an entirely online organic chemistry course. Online homework with structure-drawing capabilities was found to be more effective than written homework. Online lecture was found to be just as effective as in-person lecture, and students prefer an online lecture format with shorter Webcasts. Online office hours were found to be effective, and discussion sessions can be placed online as well. A model was created that explains 36.1% of student performance based on GPA, ACT Math score, grade in previous chemistry course, and attendance at various forms of discussion. Online exams have been created which test problem-solving skills and is instantly gradable. In these exams, students can submit answers until time runs out for different numbers of points. These facets were combined effectively to create an entirely online organic chemistry course which students prefer over the in-person alternative. Lastly, there is a vision for where online organic chemistry is going and what can be done to improve education for all.

    Energy Technology Data Exchange (ETDEWEB)

    Schiele, J.; Kurtev, I.; Ruckenbauer, E.; Stanik, Z.; Varecka, F.; Schmid, H.

    1984-03-01

    This manual is addressed to users participating in the INIS Online Service available at the IAEA in Vienna. The retrieval system used at the IAEA is IBM/STAIRS (Storage and Information Retrieval System), installed on an IBM mainframe computer operating under OS/MVS and the TP monitor CICS. STAIRS is a multipurpose software package which enables the user to carry out retrieval on suitably structured textual and/or numerical data files in both interactive (i.e. online) and batch modes. In addition to the actual retrieval modules, the system also includes a number of auxiliary facilities which assist in the preparation and management of search files, help the users in printing the document references retrieved and in saving formulated queries for later execution or SDI processing, etc. Because of certain modifications and extensions made by the IAEA, the retrieval dialogue will be slightly different from the standard STAIRS. The present manual describes the INIS/STAIRS database and the IAEA/STAIRS retrieval language.

    The increase adoption of Internet among young users in Malaysia provides high prospect for online seller. Young users aged between 18 and 25 years old are important to online sellers because they are actively involved in online purchasing and this group of online buyers is expected to dominate future online market. Therefore, examining online sellers’ website quality and online buyers’ purchase intention is crucial. Based on the Theory of planned behavior (TPB), a conceptual model of online sellers’ website quality and purchase intention of online buyers was developed. E-tailQ instrument was adapted in this study which composed of website design, reliability/fulfillment, security, privacy & trust, and customer service. Using online questionnaire and convenience sampling procedure, primary data were obtained from 240 online buyers aged between 18 to 25 years old. It was discovered that website design, website reliability/fulfillment, website security, privacy & trust, and website customer service positively and significantly influence intention of online buyers to continuously purchase via online channels. This study concludes that online sellers’ website quality is important in predicting online buyers’ purchase intention. Recommendation and implication of this study were discussed focusing on how online sellers should improve their website quality to stay competitive in online business.

    In this paper, we explore the possibilities and limitations of recovering sparse signals in an online fashion. Employing a mean field approximation to the Bayes recursion formula yields an online signal recovery algorithm that can be performed with a computational cost that is linearly proportional to the signal length per update. Analysis of the resulting algorithm indicates that the online algorithm asymptotically saturates the optimal performance limit achieved by the offline method in the presence of Gaussian measurement noise, while differences in the allowable computational costs may result in fundamental gaps of the achievable performance in the absence of noise.

    Although problem gambling is becoming more prevalent, research shows that many problem gamblers do not seek help. Online social support forums have become an increasingly popular option for receiving support for problem gambling. Few researchers have explored how participants within these forums interact, or what is supportive about participation in online communities. Melding netnography (ethnographic approaches online), discourse analysis, and ethnomethodology, we analyzed the discursive interactions of self-identified problem gamblers on an online forum. We report on the characteristics of this unique setting, the common discourses that members used, and how they discursively accomplished various interactional tasks, including constructing identities, and negotiating membership, legitimacy, and support. We conclude with recommendations for practitioners and researchers interested in better understanding people trying to overcome problem gambling and other behavioral concerns.

    2017-09-01

    This study investigated whether several psychopathology variables, including suicidality, could predict the time people spend using the internet (hours online). Next, we examined a specific at-risk population (suicidal individuals) by their online behaviors, comparing suicidal individuals who went online for suicide-related purposes with suicidal individuals who did not go online for suicide-related purposes. An anonymous online sample of 713 (aged 18-71) reported hours online, psychiatric histories, and completed several standardized scales. After accounting for age and education, hierarchical regression modeling showed that the assessed psychopathology variables, including suicidality, did not explain significant variance in hours online. Hours online were better predicted by younger age, greater willingness to develop online relationships, higher perceived social support, higher curiosity, and lower extraversion. Suicidal participants, who did or did not go online for suicide-related purposes, did not differ on hours online. Multiple regression modeling showed that those who went online for suicide-related purposes were likely to be younger, more suicidal, and more willing to seek help from online mental health professionals. These findings revealed that hours online are not a valid indicator of psychopathology. However, studying online behaviors of specific at-risk groups could be informative and useful, including for suicide prevention efforts. Copyright © 2017. Published by Elsevier B.V.

La tuberculosis extrapulmonar puede comprometer cualquier órgano, siendo el sistema genitourinario uno de los más afectados, por lo cual es importante conocer su magnitud en cada institución. Objetivos: Caracterizar la tuberculosis genitourinaria desde el punto de vista epidemiológico, clínico y paraclínico de los pacientes en los cuales la enfermedad constituyó la causa básica de muerte y su compromiso genitourinario fue un hallazgo principal de autopsia. Metodología: Estudio descriptivo retrospectivo realizado entre el 2003 y el 2008 mediante revisión de los protocolos de autopsias efectuadas en el Departamento de Patología de la Universidad Industrial de Santander, de los pacientes que fallecieron a causa de tuberculosis en el Hospital Universitario de Santander, Colombia. Resultados: Se encontraron 9 casos, con rango de edad entre 20 y 66 años, de los cuales 8 correspondían a hombres y 5 se asociaron con síndrome de inmunodeficiencia adquirida. Las manifestaciones clínicas más frecuentes fueron los síntomas constitucionales, seguido de los respiratorios, los urinarios, el dolor lumbar y los testiculares. El diagnóstico se realizó a través de los hallazgos anatomopatológicos durante la autopsia. Conclusiones: La tuberculosis genitourinaria es una forma severa de tuberculosis extra pulmonar, que por la poca especificidad del cuadro clínico, tiene un índice de sospecha bajo, lo que resulta inconveniente, ya que no permite diagnóstico oportuno, ni tratamiento adecuado para prevenir daños severos irreversibles.

Extra-pulmonary tuberculosis can compromise any organ, genitourinary system being one of the most affected therefore it is important to assess the magnitude at institutional level. Objective: Summarize the epidemiologic, clinical, and laboratory data, along patients with tuberculosis as cause of death and genitourinary tuberculosis as autopsy main finding. Methodology: A retrospective- descriptive study based on the autopsy records of the Department of Pathology of the University Industrial of Santander of 9 patients deceased from tuberculosis in the University Hospital of Santander between 2003 and 2008. Results: The range patient age was between 20 and 66 years, 8 were men and 5 had AIDS. The most common clinical manifestations were the constitutional symptoms, followed by respiratory, urinary, lumbar pain, and testicular symptoms. The anatomo-pathological and histo-pathological findings at the time of the autopsy made the diagnosis. Conclusions: Genitourinary tuberculosis is a severe form of extra-pulmonary tuberculosis, which due to its unspecific clinical picture, has a low suspicious index, resulting inconveninet, since it does not allow a timely diagnosis, or treatment to prevent irreversible severe damages.

    Full Text Available Este estudo examinou os efeitos de características da população e geográficas na chance de mamografia, no Brasil em 2003 e 2008. A partir do Suplemento Saúde da Pesquisa Nacional por Amostra de Domicílios, foram analisados os padrões de mamografia em mulheres com 25 anos ou mais, por meio de razão de prevalências, e em mulheres com 40 anos ou mais, por meio de regressão logística multivariada, incluindo o local de residência e a distribuição geográfica da oferta. Entre as mulheres com 50-69 anos, 54,6% relataram ter feito mamografia, em 2003, e 71,5%, em 2008. A chance de realização do exame é maior entre as de 50 a 69 anos, aumenta com a renda familiar e escolaridade, dentre as casadas, para as que consultaram médico e têm plano de saúde. Residir em área metropolitana triplica a chance de mamografia. Comparado com a região Norte, residentes das demais regiões têm chances maiores e a distância influencia negativamente a realização do exame. No período, a cobertura aumentou na faixa etária alvo da política nacional, com redução das desigualdades de renda e de escolaridade. A ampliação do acesso parece mais ligada às políticas de aumento de renda e inclusão social, e à ampliação da oferta de exames na rede pública e conveniada, do que ao aumento do número de mamógrafos.This study examined the effect of population characteristics and geographic location of residences and services on the odds of receiving a mammography in 2003 and 2008. Patterns of mammography use were analyzed using data from the Health Supplements of the National Household Sample Survey for women aged over 25, using prevalence ratios, and for women over 40 using multivariate logistic regression, correcting for complex sample design effects. In 2003, 54.6% of women of 50-69 years of age reported having had a mammography, in 2008, 71.5%. The odds are higher for those 50 to 69 years old, and increase with family income, education, being married, having consulted a doctor and having health insurance. Living in a metropolitan area trebles the chance of mammography. Compared to the Northern region, residents in all other regions have greater odds, greater distances decrease the odds. Coverage increased in the age range targeted by national policy, and inequalities due to income and education on access to mammography were reduced but regional convergence was not marked. Increased access seems to relate more to policies of income distribution and social inclusion, and to the availability of the examination in the Unified Health System, than to an increasing number of mammography units.

Hiperestesia cervical foi observada em todos os cães (n=28. Quanto ao grau de disfunção neurológica foram verificados: grau I (8/28[28,5%], grau II (3/28 [10,7%], grau III (5/28[17,8%] e grau V (12/2 [42,8%]. A duração dos sinais neurológicos antes da cirurgia em sete cães (25% permaneceu por até 15 dias, em 14 cães (50% entre 15 e 30 dias e nos outros sete cães (25% por mais de 30 dias. A recuperação satisfatória e sem recidiva foi observada em todos os cães submetidos ao tratamento cirúrgico e que sobreviveram (n=21. Pode-se concluir que a DDIV cervical em nossa rotina acomete principalmente cães adultos, machos, de raças condrodistróficas e não condrodistróficas, incluindo as de grande porte; a hiperestesia cervical é a principal manifestação clínica; a técnica de fenda ventral promove recuperação funcional satisfatória e sem recidiva; as principais complicações trans-operatórias são a hemorragia do plexo venoso, a bradicardia e a hipotensão; e a duração dos sinais clínicos não interfere no tempo de recuperação pós-operatória dos cães.The aim of this study was to evaluate the medical records of dogs with cervical intervertebral disk disease (IDD, submitted to surgical treatment at the Hospital Veterinário Universitário of Universidade Federal de Santa Maria (HVU-UFSM, between January 2003 and October 2008. The animal data included breed, sex, age, neurological signs and their durations, response to surgical treatment, complications, time for functional recovery after surgery, and recurrence. All dogs showed cervical hyperaesthesia confirmed by the neck movement test. Regarding the degree of neurological dysfunction, the following were verified: degree I (eight dogs, 28.5%, degree II (three dogs, 10.7%, degree III (five dogs, 17.8%, and degree V (twelve dogs, 42.8%. In relation to the duration of neurological signs prior to surgery, seven dogs (25% showed neurological deficits for up to 15 days, fourteen dogs (50% for 15 to 30 days and the other seven dogs (25% showed signs of neurological deficiencies for more than 30 days. All dogs (n=21 showed satisfactory recovery and no recurrence. It can be concluded that most affected dogs are middle aged, males and condrodystrophic and noncondrodystrophic breeds including large-breed dogs and the main neurological sign is cervical hyperaesthesia. The surgical treatment promotes satisfactory functional recovery and no recurrence, the main complications intraoperative are venous plexus hemorrhage, bradycardia and hypotension and the duration of clinical signs prior to surgery do not interfere with the recovery time of the dogs.

    2016-06-01

    Nationally, many public universities have started to move into the online course and program market that is most often associated with for-profit institutions of higher education. Administrators in public universities make statements regarding benefits to students' desire for flexibility and profit margins related to online courses. But do students attending a large public university want to take courses online especially science courses perceived to be difficult such as freshmen-level physics courses? This study took place at a large, public, Midwestern university and involved students enrolled in the first semester of a face-to-face, flipped physics course for engineering technology majors. Statements were collected from comments about online courses made by the university's administration and students in the course. Twenty students sorted 45 statements. Two student views emerged with one rejecting online courses in general and the other primarily rejecting online math, science, and technology courses, including physics. Students' descriptions of their previous online course experiences were used to inform the analyses and to assist in describing the two views that emerged in conjunction with the distinguishing statements. Consensus among the two views is also discussed. Overall, the results indicate a potential divergence between student views and what university administrators believe students want.

  1. Nutrient and chlorophyll a anomaly in red-tide periods of 2003-2008 in Sishili Bay, China

    Sishili Bay is the most important aquiculture and tourism area for the city of Yantai, China; however, red tides occurred frequently and have caused huge economic losses in this bay in recent years. To gain a better understanding of the local ecological environments in the bay, we conducted this research between 2003 and 2008 to analyze variations in nutrients and chlorophyll (chl-α) during high frequency red tide period (May to September). The results show that the chl-α concentration increased from 2.70 in 2003 to 7.26 mg/m3 in 2008, while the concentration of total inorganic nitrogen (TIN) and silicate (SiO3-Si) increased lineally from 5.18 and 1.45μmol/L in 2003 to 18.57 and 9.52 μmol/L in 2008, respectively, and the annual phosphate (PO4-P) varied between 0.15 and 0.46 μmol/L. Special attention was given to a red tide in August 2007 occurred when water temperature was high and nutrient concentrations increased sharply because of a heavy rainfall. Overall, the results show the P limitation in Sishili Bay, and reveal that red tides were caused by eutrophication from terrestrial inputs and local warm weather, particularly during rainy periods. Therefore, to control red tide, greater efforts should be made to reduce sewage discharges into Sishili Bay, particularly during rainfall seasons.

    Principal functions of the Mineral Resources Program are providing information to decision-makers related to mineral deposits on federal lands and predicting the environmental consequences of the mining or natural weathering of those deposits. Performing these functions requires that predictions be made of the likelihood of undiscovered deposits. The predictions are based on geologic and geoenvironmental models that are constructed for the various types of mineral deposits from detailed descriptions of actual deposits and detailed understanding of the processes that formed them. Over the past three decades the understanding of ore-forming processes has benefitted greatly from the integration of laboratory-based geochemical tools with field observations and other data sources. Under the aegis of the Evolution of Ore Deposits and Technology Transfer Project (EODTTP), a five-year effort that terminated in 2008, the Mineral Resources Program provided state-of-the-art analytical capabilities to support applications of several related geochemical tools.

    Full Text Available OBJECTIVE: Bisphenol A (BPA is found in plastics and other consumer products; exposure may lead to insulin resistance and development of type-2 diabetes mellitus (T2DM through over-activation of pancreatic β-cells. Previous studies using data from the National Health and Nutrition Examination Survey (NHANES showed an inconsistent association between prevalence of self-reported T2DM and urinary BPA. We used a different diagnosis method of T2DM (hemoglobin A1c (HbA1c with a larger subset of NHANES. METHODS AND FINDINGS: We analyzed data from 4,389 adult participants who were part of a sub-study of environmental phenol measurements in urine from three NHANES cycles from 2003 to 2008. T2DM was defined as having a HbA1c ≥ 6.5% or use of diabetes medication. The weighted prevalence of T2DM was 9.2%. Analysis of the total sample revealed that a two-fold increase in urinary BPA was associated with an odds ratio (OR of 1.08 of T2DM (95% confidence interval (CI, 1.02 to 1.16, after controlling for potential confounders. However, when we examined each NHANES cycle individually, we only found a statistically significant association in the 2003/04 cycle (n = 1,364, OR = 1.23 (95% CI, 1.07 to 1.42 for each doubling in urinary BPA. We found no association in either the NHANES cycle from 2005/06 (n = 1,363, OR = 1.05 (95% CI, 0.94 to 1.18; or 2007/08 (n = 1,662, OR = 1.06 (95% CI, 0.91 to 1.23. Similar patterns of associations between BPA and continuous HbA1c were also observed. CONCLUSIONS: Although higher urinary BPA was associated with elevated HbA1c and T2DM in the pooled analysis, it was driven by data from only one NHANES cycle. Additional studies, especially of a longitudinal design with repeated BPA measurements, are needed to further elucidate the association between BPA and T2DM.

    2010-01-01

    We study the online clustering problem where data items arrive in an online fashion. The algorithm maintains a clustering of data items into similarity classes. Upon arrival of v, the relation between v and previously arrived items is revealed, so that for each u we are told whether v is similar to u. The algorithm can create a new cluster for v and merge existing clusters. When the objective is to minimize disagreements between the clustering and the input, we prove that a natural greedy algorithm is O(n)-competitive, and this is optimal. When the objective is to maximize agreements between the clustering and the input, we prove that the greedy algorithm is .5-competitive; that no online algorithm can be better than .834-competitive; we prove that it is possible to get better than 1/2, by exhibiting a randomized algorithm with competitive ratio .5+c for a small positive fixed constant c.

    2015-04-01

    Peer support groups have a long history and have been shown to improve health outcomes. With the increasing familiarity with online social networks like Facebook and ubiquitous access to the Internet, online social support networks are becoming popular. While studies have shown the benefit of these networks in providing emotional support or meeting informational needs, robust data on improving outcomes such as a decrease in health services utilization or reduction in adverse outcomes is lacking. These networks also pose unique challenges in the areas of patient privacy, funding models, quality of content, and research agendas. Addressing these concerns while creating patient-centred, patient-powered online support networks will help leverage these platforms to complement traditional healthcare delivery models in the current environment of value-based care.

    2007-03-01

    Full Text Available Abstract Background Online drug information databases are used to assist in enhancing clinical decision support. However, the choice of which online database to consult, purchase or subscribe to is likely made based on subjective elements such as history of use, familiarity, or availability during professional training. The purpose of this study was to evaluate clinical decision support tools for drug information by systematically comparing the most commonly used online drug information databases. Methods Five commercially available and two freely available online drug information databases were evaluated according to scope (presence or absence of answer, completeness (the comprehensiveness of the answers, and ease of use. Additionally, a composite score integrating all three criteria was utilized. Fifteen weighted categories comprised of 158 questions were used to conduct the analysis. Descriptive statistics and Chi-square were used to summarize the evaluation components and make comparisons between databases. Scheffe's multiple comparison procedure was used to determine statistically different scope and completeness scores. The composite score was subjected to sensitivity analysis to investigate the effect of the choice of percentages for scope and completeness. Results The rankings for the databases from highest to lowest, based on composite scores were Clinical Pharmacology, Micromedex, Lexi-Comp Online, Facts & Comparisons 4.0, Epocrates Online Premium, RxList.com, and Epocrates Online Free. Differences in scope produced three statistical groupings with Group 1 (best performers being: Clinical Pharmacology, Micromedex, Facts & Comparisons 4.0, Lexi-Comp Online, Group 2: Epocrates Premium and RxList.com and Group 3: Epocrates Free (p Conclusion Online drug information databases, which belong to clinical decision support, vary in their ability to answer questions across a range of categories.

    2015-12-01

    Full Text Available Studies examining the factors that affect the online purchasing behavior of consumers are rare, despite the prospective advance of e-commerce in Malaysia. The present study examines particular factors that influence the attitude of potential consumers to purchase online by using the attributes from the diffusion of innovations theory of Rogers, the attribute of perception of risk, and the subjective norms toward online purchasing. Consumers’ perceived risks of online shopping have become a vital subject in research because they directly influence users’ attitude toward online purchasing. The structural equation modeling method was used to analyze the data gathered on students using e-commerce, and, thus, to validate the model. According to the results, consumers’ attitude toward online purchasing affects the intention toward online purchasing. The other influential factors are compatibility, relative advantage, and subjective norm.

    2009-12-01

    Presenting the complexity of geosciences to the public via the Internet poses a number of challenges. For example, utilizing various - and sometimes redundant - Web 2.0 tools can quickly devour limited time. Do you tweet? Do you write press releases? Do you create an exhibit or concept map? The presentation will provide participants with a context for utilizing Web 2.0 tools by briefly highlighting methods of online scientific communication across several dimensions. It will address issues of: * breadth and depth (e.g. from narrow topics to well-rounded views), * presentation methods (e.g. from text to multimedia, from momentary to enduring), * sources and audiences (e.g. for experts or for the public, content developed by producers to that developed by users), * content display (e.g. from linear to non-linear, from instructive to entertaining), * barriers to entry (e.g. from an incumbent advantage to neophyte accessible, from amateur to professional), * cost and reach (e.g. from cheap to expensive), and * impact (e.g. the amount learned, from anonymity to brand awareness). Against this backdrop, the presentation will provide an overview of two methods of online information dissemination, exhibits and concept maps, using the WebExhibits online museum (www.webexhibits.org) and SpicyNodes information visualization tool (www.spicynodes.org) as examples, with tips on how geoscientists can use either to communicate their science. Richly interactive online exhibits can serve to engage a large audience, appeal to visitors with multiple learning styles, prompt exploration and discovery, and present a topic’s breadth and depth. WebExhibits, which was among the first online museums, delivers interactive information, virtual experiments, and hands-on activities to the public. While large, multidisciplinary exhibits on topics like “Color Vision and Art” or “Calendars Through the Ages” require teams of scholars, user interface experts, professional writers and editors

    2010-01-01

    The number of online, distance-learning programs has increased to accommodate the needs of today's adult learners; these include new programs that feature perioperative courses for RN first assistants (RNFAs). Whereas the advantages of these programs include flexible schedules and the ability to participate at one's own pace, the disadvantages can include the lack of immediate access to faculty members who can answer questions or clarify information, and the added difficulty of learning a technical skill without hands-on training. The RNFA training program at Rock Valley College, Rockford, Illinois, is a hybrid training program that includes three phases: an online component, a hands-on workshop, and a clinical preceptorship.

    Science.gov (United States)

    Montag, M; van der Ven, H

    1999-09-01

    The use of a 1.48 um diode laser for assisted hatching was investigated in animal experimentation. Laser assisted hatching was offered to patients with advanced maternal age to evaluate a possible benefit. Using the Fertilase(r) system we investigated the impact of openings with different size in the zona of mouse embryos on the hatching process, as well as that of two openings. Laser-drilling was performed at the blastocyst stage to look for differences in timing and efficacy of hatching. The possible benefit of assisted hatching was studied in 24 couples with advanced maternal age (38.8+2.1 years) and compared to a control group (37.8+2.5 years) treated in the same time period but without assisted hatching. A certain diameter of a laser drilled opening in the zona pellucida is necessary for efficient hatching. When two openings are present in the zona, the embryo will use both openings for hatching and subsequently become trapped. Laser-drilling at th e expanded blastocyst stage causes an immediate collapse of treated blastocysts and the onset of hatching is retarded. Assisted hatching in 24 patients with advanced maternal age resulted in a significant increase (plaser to drill an opening into the zona pellucida provides a good alternate to conventionally applied techniques. The procedure is efficient and safe as long as it is applied properly. In a human in vitro fertilization program, selected patients will have a benefit form assisted hatching.

  12. Online Cake Cutting (published version)

    CERN Document Server

    Walsh, Toby

    2011-01-01

    We propose an online form of the cake cutting problem. This models situations where agents arrive and depart during the process of dividing a resource. We show that well known fair division procedures like cut-and-choose and the Dubins-Spanier moving knife procedure can be adapted to apply to such online problems. We propose some fairness properties that online cake cutting procedures can possess like online forms of proportionality and envy-freeness. We also consider the impact of collusion between agents. Finally, we study theoretically and empirically the competitive ratio of these online cake cutting procedures. Based on its resistance to collusion, and its good performance in practice, our results favour the online version of the cut-and-choose procedure over the online version of the moving knife procedure.

  15. Online Distributed Sensor Selection

    CERN Document Server

    Golovin, Daniel; Krause, Andreas

    2010-01-01

    A key problem in sensor networks is to decide which sensors to query when, in order to obtain the most useful information (e.g., for performing accurate prediction), subject to constraints (e.g., on power and bandwidth). In many applications the utility function is not known a priori, must be learned from data, and can even change over time. Furthermore for large sensor networks solving a centralized optimization problem to select sensors is not feasible, and thus we seek a fully distributed solution. In this paper, we present Distributed Online Greedy (DOG), an efficient, distributed algorithm for repeatedly selecting sensors online, only receiving feedback about the utility of the selected sensors. We prove very strong theoretical no-regret guarantees that apply whenever the (unknown) utility function satisfies a natural diminishing returns property called submodularity. Our algorithm has extremely low communication requirements, and scales well to large sensor deployments. We extend DOG to allow observatio...

    Digital media are indispensable in school, profession, family and leisure time. 1 to 6 % of all users show dsyfunctional ans addictive patterns, first of all in online and "social" media. In Switzerland over 80 % of young people own a smartphone and "pocket internet". Time of interaction with online-media (hours/day), as well as peer group pattern are markers for risk of addiction. Active music making and sports are protective factors. Family physicians are important in early recognition of "internet addictive disease". Care-givers with special experience in this field are often successful in reducing time of harmful interaction with the internet. Internet addictive disease is not yet classified in ICD and DSM-5 lists, even though it is an increasing reality.

    Full Text Available Sentiment analysis or opinion mining is used to automate the detection of subjective information such as opinions, attitudes, emotions, and feelings. Hundreds of thousands care about scientific research and take a long time to select suitable papers for their research. Online reviews on papers are the essential source to help them. The reviews save reading time and save papers cost. This paper proposes a new technique to analyze online reviews. It is called sentiment analysis of online papers (SAOOP. SAOOP is a new technique used for enhancing bag-of-words model, improving the accuracy and performance. SAOOP is useful in increasing the understanding rate of review's sentences through higher language coverage cases. SAOOP introduces solutions for some sentiment analysis challenges and uses them to achieve higher accuracy. This paper also presents a measure of topic domain attributes, which provides a ranking of total judging on each text review for assessing and comparing results across different sentiment techniques for a given text review. Finally, showing the efficiency of the proposed approach by comparing the proposed technique with two sentiment analysis techniques. The comparison terms are based on measuring accuracy, performance and understanding rate of sentences.

    Full Text Available This case study traces the evolution of library assignments for biological science students from paper-based workbooks in a blended (hands-on workshop to blended learning workshops using online assignments to online active learning modules which are stand-alone without any face-to-face instruction. As the assignments evolved to adapt to online learning supporting materials in the form of PDFs (portable document format, screen captures and screencasting were embedded into the questions as teaching moments to replace face-to-face instruction. Many aspects of the evolution of the assignment were based on student feedback from evaluations, input from senior lab demonstrators and teaching assistants, and statistical analysis of the students’ performance on the assignment. Advantages and disadvantages of paper-based and online assignments are discussed. An important factor for successful online learning may be the ability to get assistance.

    Many companies have launched their products or services online as a new business focus, but only a few of them have survived the competition and made profits. The most important key to an online business's success is to create "brand value" for the customers. Although the concept of online brand has been discussed in previous studies, there is no empirical study on the measurement of online branding. As Web 2.0 emerges to be critical to online branding, the purpose of this study was to measure Taiwan's major Web sites with a number of personality traits to build a perceptual map for online brands. A pretest identified 10 most representative online brand perceptions. The results of the correspondence analysis showed five groups in the perceptual map. This study provided a practical view of the associations and similarities among online brands for potential alliance or branding strategies. The findings also suggested that brand perceptions can be used with identified consumer needs and behaviors to better position online services. The brand perception map in the study also contributed to a better understanding of the online brands in Taiwan.

    1998-10-01

    Many multimedia applications, such as multimedia data management systems and communication systems, require efficient representation of multimedia content. Thus semantic interpretation of video content has been a popular research area. Currently, most content-based video representation involves the segmentation of video based on key frames which are generated using scene change detection techniques as well as camera/object motion. Then, video features can be extracted from key frames. However most of such research performs off-line video processing in which the whole video scope is known as a priori which allows multiple scans of the stored video files during video processing. In comparison, relatively not much research has been done in the area of on-line video processing, which is crucial in video communication applications such as on-line collaboration, news broadcasts and so on. Our research investigates on-line real-time scene change detection of multicast video over the Internet. Our on-line processing system are designed to meet the requirements of real-time video multicasting over the Internet and to utilize the successful video parsing techniques available today. The proposed algorithms extract key frames from video bitstreams sent through the MBone network, and the extracted key frames are multicasted as annotations or metadata over a separate channel to assist in content filtering such as those anticipated to be in use by on-line filtering proxies in the Internet. The performance of the proposed algorithms are demonstrated and discussed in this paper.

    Online identities play a critical role in the social web that is taking shape on the Internet. Despite many technical proposals for creating and managing online identities, none has received widespread acceptance. Design and implementation of online identities that are socially acceptable on the Internet remains an open problem. This chapter discusses the interplay between online identities and social networking. Online social networks (OSNs) are growing at a rapid pace and has millions of members in them. While the recent trend is to create explicit OSNs such as Facebook and MySpace, we also have implicit OSNs such as interaction graphs created by email and instant messaging services. Explicit OSNs allow users to create profiles and use them to project their identities on the web. There are many interesting identity related issues in the context of social networking including how OSNs help and hinder the definition of online identities.

    Full Text Available Electronic channels are rapidly taking off as a means of accessing journal literature (Lancaster, 1995. Behind the interest lies the increasing concern of academic libraries with the mounting cost of purchasing printed journals. Some commentators believe that higher-education institutions themselves will move into the electronic publishing field in order to control expenditure on journals (Okerson and O'Donnell, 1995. This rapid growth in the number of electronic journals available raises the immediate question - how will all those concerned with journals, as authors, editors, or readers, be trained? The prime purpose of the project described here is to explore the problems of providing such training. It was also planned that student feedback would assist the construction of an online teaching package.

    Full Text Available The purpose of this paper is to give to public institution Web designers a better understanding of the citizens’ objectives when accessing a Web page. Understanding citizen online goals is critical because it gets to the heart of what the public institution website should or could “do.” Approach: The challenge for e-marketers is that for most agencies/institutions, there are likely to be multiple goals that represent the “reason why” citizens could come to the website. For example, a national theatre website might be very effective for people who have already been there, they know effectively what place is the best, who are the actors, etc. Research limitations: The nature of a public institution activity almost dictates the different types of goals that consumers have when visiting the site. It is clear that a citizen has a different goal when accessing a theatre Web page or when he’s accessing a municipality Web page. This is the biggest impediment for drawing a good conceptual model for a public institution Web page. Practical implications: there are likely to be many other goals that could lead people to visit the site, like receiving customer service or leaving a remark. Value: Since citizen online goals represent the starting point for Web design efforts (for public institutions, this article has attempted to highlight the nature and types of goals that e-marketers might consider when planning what their website should do in order to create.

    2013-12-01

    Traditional large lecture classes are fundamentally passive and teacher-centered. Most existing online courses are as well, including massive open online courses (MOOCs). Research tells us that this mode of instruction is not ideal for student learning. However, the unique attributes of the online environment have thus far been mostly underutilized. We hypothesize that new tools and the innovative curricula they enable can foster greater student engagement and enhance learning at large scale. To test this hypothesis, over the past three years, Arizona State University developed and offered "Habitable Worlds", an online-only astrobiology lab course. The course curriculum is based on the Drake Equation, which integrates across disciplines. The course pedagogy is organized around a term-long, individualized, game-inspired project in which each student must find and characterize rare habitable planets in a randomized field of hundreds of stars using concepts learned in the course. The curriculum allows us to meaningfully integrate concepts from Earth, physical, life, and social sciences in order to address questions related to the possibility of extraterrestrial life. The pedagogy motivates students to master concepts, which are taught through interactive and adaptive inquiry-driven tutorials, featuring focused feedback and alternative pathways that adjust to student abilities, built using an intelligent tutoring system (Smart Sparrow's Adaptive eLearning Platform - AeLP). Through the combination of the project and tutorials, students construct knowledge from experience, modeling the authentic practice of science. Because the tutorials are self-grading, the teaching staff is free to dedicate time to more intense learner-teacher interactions (such as tutoring weaker students or guiding advanced students towards broader applications of the concepts), using platforms like Piazza and Adobe Connect. The AeLP and Piazza provide robust data and analysis tools that allow us to

  5. Assisted suicide and euthanasia.

    Science.gov (United States)

    van der Heide, Agnes

    2013-01-01

    Several countries have adopted laws that regulate physician assistance in dying. Such assistance may consist of providing a patient with a prescription of lethal medication that is self-administered by the patient, which is usually referred to as (physician) assistance in suicide, or of administering lethal medication to a patient, which is referred to as euthanasia. The main aim of regulating physician assistance in dying is to bring these practices into the open and to provide physicians with legal certainty. A key condition in all jurisdictions that have regulated either assistance in suicide or euthanasia is that physicians are only allowed to engage in these acts upon the explicit and voluntary request of the patient. All systems that allow physician assistance in dying have also in some way included the notion that physician assistance in dying is only accepted when it is the only means to address severe suffering from an incurable medical condition. Arguments against the legal regulation of physician assistance in dying include principled arguments, such as the wrongness of hastening death, and arguments that emphasize the negative consequences of allowing physician assistance in dying, such as a devaluation of the lives of older people, or people with chronic disease or disabilities. Opinion polls show that some form of accepting and regulating euthanasia and physician assistance in suicide is increasingly supported by the general population in most western countries. Studies in countries where physician assistance in dying is regulated suggest that practices have remained rather stable in most jurisdictions and that physicians adhere to the legal criteria in the vast majority of cases.

  6. Trust and Online Reputation Systems

    Science.gov (United States)

    Kwan, Ming; Ramachandran, Deepak

    Web 2.0 technologies provide organizations with unprecedented opportunities to expand and solidify relationships with their customers, partners, and employees—while empowering firms to define entirely new business models focused on sharing information in online collaborative environments. Yet, in and of themselves, these technologies cannot ensure productive online interactions. Leading enterprises that are experimenting with social networks and online communities are already discovering this fact and along with it, the importance of establishing trust as the foundation for online collaboration and transactions. Just as today's consumers must feel secure to bank, exchange personal information and purchase products and services online; participants in Web 2.0 initiatives will only accept the higher levels of risk and exposure inherent in e-commerce and Web collaboration in an environment of trust. Indeed, only by attending to the need to cultivate online trust with customers, partners and employees will enterprises ever fully exploit the expanded business potential posed by Web 2.0. But developing online trust is no easy feat. While various preliminary attempts have occurred, no definitive model for establishing or measuring it has yet been established. To that end, nGenera has identified three, distinct dimensions of online trust: reputation (quantitative-based); relationship (qualitative-based) and process (system-based). When considered together, they form a valuable model for understanding online trust and a toolbox for cultivating it to support Web 2.0 initiatives.

    2014-04-01

    Full Text Available Open and free internet-based platforms are seen as an enabler of global free expression, releasing writers from commercial and space constraints. However, many are working without the assistance of an in-house lawyer, or other legal resources. This may lead to undue suppression of public interest material, with important implications for freedom of expression and the democratic function of media. Two online surveys among digital and online journalists in England and Wales in 2013 indicated that the majority of encounters with defamation and privacy law take place outside the courts, with few formally recorded legal actions. This was particularly evident in a sample of ‘hyperlocal’ and local community publishers. In light of the results, this paper calls for a reappraisal of overly simplistic judicial and media applications of the ‘chilling effect’ doctrine, in order to expose its subjectivities and complexities. Additionally, attention needs to be paid to global and cross-jurisdictional media-legal environments, in order to help develop better internet policy and legal frameworks for protecting legitimate expression.

In contrast to existing works (Kar, Sriperumbudur, Jain, & Karnick, 2013 ; Wang, Khardon, Pechyony, & Jones, 2012 ), which require that the iterates are restricted to a bounded domain or the loss function is strongly convex, OPERA is associated with a non-strongly convex objective function and learns the target function in an unconstrained RKHS. Specifically, we establish a general theorem that guarantees the almost sure convergence for the last iterate of OPERA without any assumptions on the underlying distribution. Explicit convergence rates are derived under the condition of polynomially decaying step sizes. We also establish an interesting property for a family of widely used kernels in the setting of pairwise learning and illustrate the convergence results using such kernels. Our methodology mainly depends on the characterization of RKHSs using its associated integral operators and probability inequalities for random variables with values in a Hilbert space.

  16. Barter Online Network

    2015-12-01

    Full Text Available Barter is the direct exchange of goods or services without using a medium of exchange, such as money. Barter faced a number of limitations, and according to Smith (1776, these limitations led to the emergence of money. However, trading with money also exposes traders to the problems of monetary economy such as inflation, deflation, currency de-valuation, and currency exchange fluctuation. According to Statista.com (2015, in 2016, global Business to Customer (B2C e-commerce sales will reach 1.92 trillion US dollars. On the other hand, online barter solutions are rare on the market. The only attempts to tackle online barter are mobile applications, carried out by small businesses. The market gap is caused by the unsolved inefficiencies of barter. The aim of this thesis is to identify the problems of barter, propose an IT solution for the problems of barter, and finally, produce an artefact, which is the realisation of the proposed IT solution by utilising computer systems and computer algorithms.

    2008-07-01

    The purpose of this study was to determine how a traditional weight training class compared to nontraditional classes that were heavily laden with technology. Could students learn resistance exercises by watching video demonstrations over the Internet? Three university weight training classes, each lasting 16 weeks, were compared. Each class had the same curriculum and workout requirements but different attendance requirements. The online group made extensive use of the Internet and was allowed to complete the workouts on their own at any gym that was convenient for them. Seventy-nine college-aged students were randomized into 3 groups: traditional (n = 27), hybrid (n = 25), and online (n = 27). They completed pretest and posttest measures on upper-body strength (i.e., bench press), lower-body strength (i.e., back squat), and knowledge (i.e., written exam). The results indicated that all 3 groups showed significant improvement in knowledge (p students to attend class and may have resulted in significantly lower scores on the bench press (p motivation, low accountability, and the possibility that the self-reported workouts were not accurate. These results suggest that there is a limit to how much technology can be used in a weight training class. If this limit is exceeded, some type of monitoring system appears necessary to ensure that students are actually completing their workouts.

    2017-01-01

    Online neuropsychological test batteries could allow for large-scale cognitive data collection in clinical studies. However, the few online neuropsychological test batteries that are currently available often still require supervision or lack proper psychometric evaluation. In this paper, we have outlined prerequisites for proper development and use of online neuropsychological tests, with the focus on reliable measurement of cognitive function in an unmonitored setting. First, we identified several technical, contextual, and psychological factors that should be taken into account in order to facilitate reliable test results of online tests in the unmonitored setting. Second, we outlined a methodology of quality assurance needed in order to obtain reliable cognitive data in the long run. Based on factors that distinguish the online unmonitored test setting from the traditional face-to-face setting, we provide a set of basic requirements and suggestions for optimal development and use of unmonitored online neuropsychological tests, including suggestions on acquiring reliability, validity, and norm scores. When properly addressing factors that could hamper reliable test results during development and use, online neuropsychological tests could aid large-scale data collection for clinical studies in the future. Investment in both proper development of online neuropsychological test platforms and the performance of accompanying psychometric studies is currently required.

    Full Text Available The adaptation of information technology to everyday clinical practices coincided with the emergence of online databases, personal medical history and institutional information websites. One of the central issues in online medicine is source credibility. This paper overviews the types and communication of online medical information that have changed the logistics of doctor-patient communication. Inter-doctor communication also benefits from the possibilities for professional communication, and application of multiprofessional knowledge; it helps shape and unify professional terms and nomenclature, guarantees the confidentiality and security of data, while providing easy management of high-quality data; makes provisions for knowledge management and ambulatory e-services.The paper overviews the information portal Kliinik.ee (www.kliinik.ee, OÜ Tervisenõuanne which shares medical information made available by medical professionals for non-medics, mostly for patients. The portal offers a range of e-medicine services, such as responses by specialists, psychologists, pharmacists. The Communication groups offer the patients free medical advice, feedback, a second opinion to their treatment scheme, as well as an opportunity to share knowledge and their personal experiences, and receive emotional support. Writing therapy is becoming increasingly popular and has spontaneously moved online. Today, there are discussion forums available for people suffering from diabetes, cancer and other serious (or incurable medical problems. The Internet is in manyrespects advantageous for this type of therapy: it provides an opportunity to establish a dialogue with others with a similar condition while protecting one’s privacy and anonymity. Medical professionals post comments under their own names which gives them credibility.Seeking medical help at an institutional site from practising doctors makes the language use and attitudes of the online forum official

    2011-07-01

    Full Text Available Learning and teaching online imposes certain challenges on both students and teachers. Teachers should be prepared to meet special requirements of teaching online. Teachers play an important role in teaching. Roles of teachers increase with introducing the online learning, contrary to an early assumption perceived with the invention of the Internet. Designing and developing online courses need collaboration of several people with a variety of interests and expertise, including administrators, teachers, designers, and technical specialists. Each course within the curriculum should be well-designed and fit well within the curriculum. The curriculum in turn should reflect the current state of the discipline, enabling the learners to develop appropriate proficiency and mastery within the specific discipline. This paper describes the roles of teachers and administrators in online learning, and discusses the rules of best practices for both.

    Directory of Open Access Journals (Sweden)

    Petric (Iancu Ioana Ancuta

    2015-07-01

    Full Text Available In terms of marketing, online trading is a new distribution channel and trading platforms are products of Investment and Financial Services Companies. Internet shortens the connection between the investor and the products they wish to purchase (shares, futures, CFDs, government securities, bonds, etc., and in some cases it no longer needs a security broker. Increasing use of the Internet and increasing competitiveness between Investment and Financial Services Companies do the latter, to seek new distribution channels to specific products. The purpose of this paper is to examine to what extent the investor education level affects the decision to move from traditional trading to online trading and the benefits and disadvantages of these types of transactions. To whom should the Investment and Financial Services Companies guide their marketing campaign to attract more investors for online platforms? The work presented is part of a larger project that will be part of author thesis, studying other factors that influence the decision to move from traditional to online trading: cost factor, time factor, psychological and social attributes of investors, yield portfolios and technological capacities of Investment and Financial Services Companies. Starting from the idea that with the increase of experience in stock investments the investors will want to make their own decisions, Investment and Financial Services Companies should provide new products. Compared to competitors, an Investment and Financial Services Company must innovate, and information technology currently offers the tools for innovation facilities. At the same time, the existence and development of the Internet has made the transaction without assistance or with minimal human intervention possible (Voss, 2000. The difference is in the knowledge about stock market, the speed the transaction orders arrive in the stock market, direct access to multiple markets, transaction costs and the level

  8. Ethics in Online Publications.

    Science.gov (United States)

    Vervaart, Peter

    2014-10-01

    Journals have been publishing the results of scientific investigations since the founding of Philosophical Transactions in 1665. Since then we have witnessed a massive expansion in the number of journals to the point that there are now approximately 28,000 active, peer reviewed journals collectively publishing more than 1.8 million articles per year. Before the mid-1990s, these journals were only available on paper but by the end of the 20th century, most journals had moved to online platforms. Online publication has also served as the impetus for the move to 'open-access' to the information contained in journals. The fact that a publication is 'on-line' and 'open-access' does not negate the responsibility of the author and the publisher to publish in an ethical way. [1] The document produced by the IFCC Ethics Task Force (TF-E) on publication ethics states that 'Ethics in Science at its broadest level encompasses research ethics, medical ethics, publication ethics, conflicts of interest, ethical responsibilities as educator, plus many other areas.' Thus publication ethics is a continuum from the first step of research design through to the information being read by the reader. In general terms 'publication ethics' includes the ethical behaviour of the authors in writing and submitting a scientific manuscript to a publisher for the purpose of publication, thus any discussion of publication ethics must include the role of the authors, referees, publisher and reader and the issues of authorship (and the use of 'ghosts'), plagiarism, duplicate publication (including in different languages), image manipulation (particularly in the era of digitisation), and conflict of interest [2]. To aid the authors, and others involved in the process of publication, a number of resources are now available particularly those from the Committee on Publication Ethics (COPE) [3] and the World Association of Medical Editors (WAME) [4]. More recently the issue of 'publisher ethics' has

During the past five years, the WAPTAC has developed into the premier source for information related to operating the Weatherization Assistance Program (WAP) at the state and local levels. The services provide through WAPTAC include both virtual technical support as well as hands-on training and instruction in classroom and in the field. The WAPTAC achieved several important milestones during its operation including the establishment of a national Weatherization Day now celebrated in most states, the implementation of a comprehensive Public Information Campaign (PIC) to raise the awareness of the Program among policy makers and the public, the training of more than 150 new state managers and staff as they assume their duties in state offices around the country, and the creation and support of a major virtual information source on the Internet being accessed by thousands of staff each month. The Weatherization Assistance Program Technical Assistance Center serves the Department of Energy's (DOE) Office of Weatherization and Intergovernmental Program as a valuable training and technical assistance resource for the network of 54 direct state grantees (50 states, District of Columbia and three Native American tribes) and the network of 900 local subgrantees (comprised of community action agencies, units of local government, and other non-profit organizations). The services provided through WAPTAC focus on standardizing and improving the daily management of the WAP. Staff continually identify policies changes and best practices to help the network improve its effectiveness and enhance the benefits of the Program for the customers who receive service and the federal and private investors.

    Full Text Available The advantages of electronic retailing can, among other things, result in uncontrolled buying by online consumers, i.e. in extreme buying behavior. The main purpose of this paper is to analyze and determine the buying patterns of Generation Y online consumers in order to explore the existence of different types of behavior based on the characteristics of online buying. The paper also aims at exploring the relationship between extracted factors and Generation Y consumers’ buying intentions. Empirical research was conducted on a sample of 515 consumers in the Dubrovnik-Neretva County. Based on the factor analysis, research results indicate that Generation Y online consumers are influenced by three factors: compulsivity, impulsivity, and functionality. The analysis of variance reveals that significant differences exist between the extracted factors and Generation Y’s online buying characteristics. In addition, correlation analysis shows a statistically significant correlation between the extracted factors and Generation Y’s buying intentions.

    Various fields have examined the activity of flirting, predominantly based on experimental and reported data; the interactional workings are therefore often overlooked. Based on emails and chats from two Danish online dating sites, this article investigates how users negotiate romantic connections...... through the flirting strategy of ‘imagined togetherness’, linguistically constructing imagery of a shared future. Using the notion of the chronotope (Bakhtin 1981), turn-by-turn analysis demonstrates how users, embedded in the activity of getting to know each other, tenuously communicate romantic interest...... by alluding to future points at which they might be together. Central to the strategy is a sequential pattern of avoiding closure and thereby preserving the imagery’s implicitness. The article concludes by arguing that while imagined togetherness functions a way of probing interests and thus protecting...

With an increasing emphasis on the emerging automatic personal identification applications, fingerprint based identification is becoming more popular. The most widely used fingerprint representation is the minutiae based representation. The main drawback with this representation is that it does not utilize a significant component of the rich discriminatory information available in the fingerprints. Local ridge structures cannot be completely characterized by minutiae. Also, it is difficult quickly to match two fingerprint images containing different number of unregistered minutiae points. In this study filter bank based representation, which eliminates these weakness, is implemented and the overall performance of the developed system is tested. The results have shown that this system can be used effectively for secure online verification applications.

    Full Text Available Online higher education is steadily increasing. For programs in allied health to be offered effectively in an elearning format, clinical psychomotor skills need to be addressed. The aim of this research was to design, implement, and evaluate an online safe patient transfers module for occupational therapy assistant (OTAstudents. The efficacy of teaching safe patient transfers in an e-learning environment was appraised using both quantitative and qualitative analysis. The applied research project was completed at a Tennessee community college. A convenience sample of eighteen students participated in the pilot study. Twenty-five studentsparticipated in the subsequent study. The instructional design of the course was based on Mager’s CriterionReferenced Instruction model. Streaming video was used as the delivery method for course material. A pretest/posttest evaluated the students’ cognitive knowledge of safe patient transfers. A behavioral transferscompetency checklist was used to rate videotapes of students’ performance of assisted stand pivot and dependent sliding board transfers. Research findings indicated students were able to learn this psychomotor clinical skill online with beginning proficiency. A paired t-test showed marked improvement of cognitive knowledge. A student learning survey revealed the majority of students preferred at least one hands-on classroom session where instructor feedback and interaction with classmates confirmed safe and effectiveclinical technique.

    2010-06-01

    Robotic surgery has evolved over the last decade to compensate for limitations in human dexterity. It avoids the need for a trained assistant while decreasing error rates such as perforations. The nature of the robotic assistance varies from voice activated camera control to more elaborate telerobotic systems such as the Zeus and the Da Vinci where the surgeon controls the robotic arms using a console. Herein, we report the first series of robotic assisted colectomies in Ireland using a voice activated camera control system.

  6. Online Learning: Social Interaction and the Creation of a Sense of Community

    Directory of Open Access Journals (Sweden)

    Tim S Roberts

    2004-07-01

    Full Text Available This paper centres on the sense of isolation that online study may engender among learners, a factor often ignored by many educators, but one that may make the difference between a successful and an unsuccessful online learning environment for many students. The importance of a proper appreciation of the learners’ social context is stressed, as is the concept of the ‘virtual self’ that individual learners may choose to portray during online communication.The authors suggest three protocols that can be built into the fabric of online courses in order that a sense of community may be enabled to exist, and productive social interaction can occur. These are (1 the greater use of synchronous communication facilities (in addition to, rather than instead of, asynchronous ones, (2 the deliberate design and inclusion of a ‘forming’ stage, or ‘warm-up’ period, incorporated as an essential component into the course structure, and (3 a much greater emphasis on the provision of (and adherence to guidelines for successful online communication.The paper concludes by suggesting that by creating an online sense of ‘self’, the participants of an online course can alleviate feelings of isolation, and create an online community that assists the learning process.

    Wilson, Samara R; Rodda, Simone; Lubman, Dan I; Manning, Victoria; Yap, Marie B H

    2017-07-01

    Problematic alcohol and other drug (AOD) use impacts partners heavily, with an increased risk of experiencing domestic violence, financial stressors, health problems and relationship challenges. However, partners often do not seek help or support due to a range of barriers (e.g., shame, stigma, practical constraints). Online counselling may facilitate help-seeking by overcoming many of these barriers, however research is needed to explore what motivates partners to contact online counselling services, their experiences and needs, and how partners can be best supported online. One hundred transcripts of partners of individuals with problem AOD use were sampled from a 24-hour national AOD synchronous online chat counselling service. Descriptive content analysis was used to investigate themes related to help-seeking. Three broad themes, with seven sub-themes, were identified: (i) the reason for accessing online counselling (seeking advice, wanting to talk), (ii) discussing help-seeking and coping processes (past/present help-seeking or coping strategies, barriers and facilitators to seeking help and change), and (iii) planning for future assistance (future planning, treatment preferences). Partners wanted to talk about their concerns with a non-judgemental professional. However, the majority of help-seekers wanted advice and assistance in problem-solving, coping and the process of seeking further help. Future studies need to examine the impact of online help-seeking by partners. Copyright © 2017 Elsevier Inc. All rights reserved.

  7. Supplemental Instruction Online: As Effective as the Traditional Face-to-Face Model?

    Science.gov (United States)

    Hizer, Suzanne E.; Schultz, P. W.; Bray, Richard

    2016-10-01

    Supplemental Instruction (SI) is a well-recognized model of academic assistance with a history of empirical evidence demonstrating increases in student grades and decreases in failure rates across many higher education institutions. However, as college students become more accustomed to learning in online venues, what is not known is whether an SI program offered online could benefit students similarly to SI sessions that occur in face-to-face settings. The in-person (traditional) SI program at California State University San Marcos has demonstrated increases in grades and lower fail rates for courses being supported in science and math. Students enrolled in four biology courses who participated in online SI received increases in academic performance similar to the students in the courses who attended traditional SI. Both the online and traditional SI participating students had higher course grades and lower fail rates as compared to students who did not participate in either form of SI. Self-selection, as measured by past cumulative college grade point average, did not differ between students who attended either form of SI or who did not attend. Student perceptions of online SI were generally positive and appeared to offer an alternative path to receive this valuable academic assistance for some students. Overall, results are promising that the highly effective traditional model can be translated to an online environment.

    Introduction Accessibility and assistive products and technologies are needed to ensure the rights of persons with disabilities and older persons. Many developments have been implemented in laws, standards, markets and from the consumers perspective, at international, European and national levels. The real issue is that not all the potential users benefit from the use of assistive products or accessible measures. Discussion Innovative methods are needed to allow all potential users to have real advantage of assistive technologies and accessible and design for all facilities. Best practices will be presented and existing gaps and recommendations will be discussed. Cost-benefits aspects will also be presented. Conclusion In order to get advantages from opportunities of globalization, hard work and responsibilities of all stakeholders are needed, so that assistive products and accessibility reach a whole range of situations and environments and contribute to ensure quality of life in a society for all.

    2014-04-01

    According to the National Registry of Renal Replacement Therapy (RRT), the incidence of chronic kidney disease (end-stage renal disease) and the need of RRT have declined in the last decade renal. One of the reasons for this tendency certainly is transplantation as the best choice. However, transplant procedure has limitations in elderly patients due to the number of comorbidities. This study was designed as retrospective analysis of outcomes in patients treated with peritoneal dialysis for a period of eleven years. Patients were divided into those who had been assisted or unassisted. Out of 100 patients treated with peritoneal dialysis (PD), 77 completed the treatment, including 26 assisted and 51 unassisted patients. Peritonitis was recorded in 20 assisted and 26 unassisted patients. Peritonitis was more common in unassisted patients, who were more frequently lost from PD. Assisted PD could be a good and safe choice of RRT in this special group of patients.

    The Equipment Buyers Guide was edited by Jo Rita Jordan. The new Equipment Buyers Guide, bound into the back of this issue, is also a new resource of JCE Internet. This resource provides an online source for the information contained in the printed guide. Placing this information online allows us to regularly update it and to provide live links to the suppliers' WWW sites. The organization of the online version parallels that of the print version. There is an alphabetical list of suppliers and a categorical listing. Links to these lists are provided on every page in the left-hand navigation bar. To quickly find information about a particular supplier, you click Supplier List, click the letter that begins the supplier's name, and scroll through the list to find the supplier. To find which suppliers provide a particular type of instrument or equipment, use the Categories link; click the category of the equipment you are looking for and then click the link to a supplier. You will then be taken to an alphabetical supplier listing page where you can scroll until you find the particular supplier of the item for which you are looking. Once you have found a supplier, the online Equipment Buyers Guide gives you the traditional contact information. But in addition, you also get one-click access to the WWW sites of the suppliers that have them. Depending on the site, you should be able to find information about the items that you seek and may even be able to order the items online! We think that you will find the online version of the Equipment Buyers Guide useful. To make it more useful, please send your suggestions, any errors or omissions you find, and any additional categories to the editor at jjordan@world.std.com The online Equipment Buyers Guide can be found at JCE Online at http://JChemEd.chem.wisc.edu/JCEWWW/Resources/EBG/ JCE Online in '99 JCE Online is your online source of "all things JCE".

    Online-delivered distance education is a burgeoning component of professional development and continuing education. Distance education programs allow individuals to learn in a different location and/or at a different time from fellow learners, thereby increasing the flexibility and number of learning options. Selecting the "right" program for personal development from the ever-growing body of online-delivered education is an individualized decision that can become an overwhelming and challenging process. This Tool presents four important definitions for navigating distance education program description materials and outlines a five-step process to assist in identifying an appropriate program for personal development. The five-step process includes key questions and points to consider while conducting a candid self-assessment, identifying and investigating distance education programs, and then compiling information, comparing programs, and prioritizing a list of programs suitable for application. Furthermore, this Tool highlights important websites for distance education degree program reviews, accreditation information, and open educational resources.

    Medical physicists are often involved in the didactic training of graduate students, residents (both physics and physicians), and technologists. As part of continuing medical education, we are also involved in maintenance of certification projects to assist in the education of our peers. As such, it is imperative that we remain current concerning available educational resources. Medical physics journals offer book reviews, allowing us an opportunity to learn about newly published books in the field. A similar means of communication is not currently available for online educational resources. This information is conveyed through informal means. This review presents a summary of online resources available to the medical physics community that may be useful for educational purposes.

CALL emphasizes the learner and suggests a student-centered approach. It experiences three time periods, the 1960s and 1970s, the 1980s, and the 1990s and now played an important role in foreign language teaching. CALL is employed in many ways, both in and out of class room. Delivery methods for CALL include individual computers at home or in the classroom, classroom sets of computers, language labs into which computer functions have been incorporated, online instruction through the WWW and distance and networked learning through the use of email.

    The article presents and condenses the background, findings and results of a one yearlong research project on online supervision and feedback at the university. The article builds on presentations and discussions in different research environments and conferences on higher education research...... supervision proves unhelpful when trying to understand how online supervision and feedback is a pedagogical phenomenon in its own right, and irreducible to the face-to-face context. Secondly we show that not enough attention has been given to the way different digital tools and platforms influence...... the supervisory dialogue in the specific supervision context. We conclude by terming this challenge in online supervision a form of ‘torn pedagogy’; that online tools and platforms destabilise and ‘tear’ traditional understandings of supervision pedagogy ‘apart’. Also, we conclude that on the backdrop of a torn...

    Recently online communities have attracted great interest and have become an important medium of information exchange between users. The aim of this work is to introduce a simple model of the evolution of online communities. This model describes (a) the time evolution of users’ activity in a web service, e.g., the time evolution of the number of online friends or written posts, (b) the time evolution of the degree distribution of a social network, and (c) the time evolution of the number of active users of a web service. In the second part of the paper we investigate the influence of the users’ lifespan (i.e., the total time in which they are active in an online community) on the process of rumor propagation in evolving social networks. Viral marketing is an important application of such method of information propagation.

  16. Stability Conditions for Online Learnability

    CERN Document Server

    Ross, Stephane

    2011-01-01

    Stability is a general notion that quantifies the sensitivity of a learning algorithm's output to small change in the training dataset (e.g. deletion or replacement of a single training sample). Such conditions have recently been shown to be more powerful to characterize learnability in the general learning setting under i.i.d. samples where uniform convergence is not necessary for learnability, but where stability is both sufficient and necessary for learnability. We here show that similar stability conditions are also sufficient for online learnability, i.e. whether there exists a learning algorithm such that under any sequence of examples (potentially chosen adversarially) produces a sequence of hypotheses that has no regret in the limit with respect to the best hypothesis in hindsight. We introduce online stability, a stability condition related to uniform-leave-one-out stability in the batch setting, that is sufficient for online learnability. In particular we show that popular classes of online learners...

They differ among themselves in the character of the service they provide to online users. For instance, Facebook can be seen mainly as a platform for keeping in touch with close friends and relatives, Twitter is used to propagate and receive news, LinkedIn facilitates the maintenance of professional contacts, Flickr gathers amateurs and professionals of photography, etc. Albeit different, all these online platforms share an ingredient that pervades all their applications. There exists an underlying social network that allows their users to keep in touch with each other and helps to engage them in common activities or interactions leading to a better fulfillment of the service's purposes.

    We describe herein the cases of 2 patients who had ventricular arrhythmias. In one, a short-term biventricular assist device, the ABIOMED BVS 5000, was placed because the patient had sustained ventricular tachycardia and could not be weaned from cardiopulmonary bypass. Excellent hemodynamic support was maintained for several days while the antiarrhythmic therapy was maximized. Sinus rhythm was restored, and the patient was successfully weaned from the ventricular assist device. However, the substrate for the arrhythmia persisted, and a recurrence, 1 week later, resulted in the patient's death. In the 2nd patient, the use of an implantable left ventricular assist device was successful in temporarily alleviating the ventricular tachycardia associated with ischemic cardiomyopathy. However, after 2 days of device assistance, the patient experienced a recurrence of the tachycardia, which degenerated into ventricular fibrillation with a marked deterioration in the patient's hemodynamics. The arrhythmia persisted despite multiple attempts at external cardioversion, and internal cardioversion and placement of an automatic implantable cardioverter-defibrillator were necessary. This treatment, along with repeated boluses of amiodarone, led to successful suppression of the arrhythmias, and the patient eventually underwent transplantation. The mechanical hemodynamic support of the circulation by ventricular assist devices was effective in supporting these 2 patients who had sustained ventricular arrhythmias.

    Single aerosol particles were measured by matrix-assisted laser desorption/ionization (MALDI) with an aerosol time-of-flight mass spectrometer (ATOFMS). The inlet to the ATOFMS was coupled with an evaporation/condensation flow cell that allowed matrix addition by condensation onto the particles. The coated particles entered the ion source through three-stage differentially pumped capillary inlet and were then ionized by a focused 266 nm Nd:YAG laser. The mass spectra and aerodynamic size of the single particles can be obtained simultaneously. The on-line matrix addition technique makes it possible to identify biological aerosols in real-time.

    A mobile autonomous humanoid robot is assisting human co-workers at the Johnson Space Center with tool handling tasks. This robot combines the upper body of the National Aeronautics and Space Administration (NASA)/Defense Advanced Research Projects Agency (DARPA) Robonaut system with a Segway(TradeMark) Robotic Mobility Platform yielding a dexterous, maneuverable humanoid perfect for aiding human co-workers in a range of environments. This system uses stereo vision to locate human team mates and tools and a navigation system that uses laser range and vision data to follow humans while avoiding obstacles. Tactile sensors provide information to grasping algorithms for efficient tool exchanges. The autonomous architecture utilizes these pre-programmed skills to form human assistant behaviors. The initial behavior demonstrates a robust capability to assist a human by acquiring a tool from a remotely located individual and then following the human in a cluttered environment with the tool for future use.

    2014-02-01

    Full Text Available This paper describes an embedded approach to learner support in online English language courses. The support model is based on language acquisition, transactional distance, and self-regulated learning theories. Based on these theories, courses were designed to provide the interaction necessary for academic English language gains, decrease the transactional distance between the teacher and learner, and assist learners in developing the ability to control the factors that affect their learning; in other words, to be self-regulated learners. The latter is critical for those who lack the autonomy needed for successful distance learning. In this paper, three course activities are described and analyzed to demonstrate how the embedded support model responds to the needs of diverse learners and assists them in achieving identified outcomes. The courses were designed for off-site international students enrolled in traditional English-speaking higher education institutions.http://dx.doi.org/10.5944/openpraxis.6.1.90

    2013-09-01

    Full Text Available A proliferation of retail online training materials exists, but often the person in charge of choosing the most appropriate online training materials is not versed in best practices associated with online training. Additionally, the person must consider the context of the training situation when choosing a training solution. To assist this decision-making process an evaluation instrument was developed. The instrument was designed to help decision-makers 1 assess multiple online training programs against known best practices, and 2 consider context specific training needs via a weighting process. Instrument testing across multiple online training programs was performed, and weighted and unweighted results were examined to determine the impact of contextualized weighting. Additionally, evaluation data from the new instrument were compared to data from an existing online training evaluation instrument. Results indicated the new instrument allowed for consistent rankings by raters across multiple programs, and when the new weighting process was applied small differences were magnified making them more noticeable in overall rating scores. Thus the new weighted instrument was effective in 1 assessing multiple online training programs, and 2 providing reviewers clearer context-specific rating data on which they could make purchasing decisions.

    Full Text Available Blurring the Boundaries? Supporting Students and Staff within an Online Learning Environment Dr Susannah QUINSEE Head of E-Learning City University London, THE UNITED KINDOM Judith HURST Senior Lecturer School of Nursing and Midwifery London, THE UNITED KINDOM ABSTRACT The inclusion of online learning technologies into the higher education (HE curriculum is frequently associated with the design and development of new models of learning. One could argue that e-learning even demands a reconfiguration of traditional methods of learning and teaching. One of the key elements of this transformational process is flexibility. This paper considers a number of aspects relating to the flexibility inherent within models of online learning and the potential impact of this on support structures. City University, London, is used as a case study to provide examples of online practice which support strategies outlined here. A number of models of online learning are used at the University to provide evidence of the variation in modes of support and illustrate the different needs of both students and staff when using these forms of learning. What is apparent through this discussion is that to provide effective support for online learners, whether students or staff, clear and solid structures need to be put in place to assist with the creation of an online community.

    The overall goal of this study is to address issues of environmental health and enhance public health decision making by utilizing NASA remotely-sensed data and products. This study is a collaboration between NASA Marshall Space Flight Center, Universities Space Research Association (USRA), the University of Alabama at Birmingham (UAB) School of Public Health and the Centers for Disease Control and Prevention (CDC) National Center for Public Health Informatics. The objectives of this study are to develop high-quality spatial data sets of environmental variables, link these with public health data from a national cohort study, and deliver the linked data sets and associated analyses to local, state and federal end-user groups. Three daily environmental data sets were developed for the conterminous U.S. on different spatial resolutions for the period 2003-2008: (1) spatial surfaces of estimated fine particulate matter (PM2.5) exposures on a 10-km grid utilizing the US Environmental Protection Agency (EPA) ground observations and NASA s MODerate-resolution Imaging Spectroradiometer (MODIS) data; (2) a 1-km grid of Land Surface Temperature (LST) using MODIS data; and (3) a 12-km grid of daily Solar Insolation (SI) and maximum and minimum air temperature using the North American Land Data Assimilation System (NLDAS) forcing data. These environmental datasets were linked with public health data from the UAB REasons for Geographic and Racial Differences in Stroke (REGARDS) national cohort study to determine whether exposures to these environmental risk factors are related to cognitive decline and other health outcomes. These environmental national datasets will also be made available to public health professionals, researchers and the general public via the CDC Wide-ranging Online Data for Epidemiologic Research (WONDER) system, where they can be aggregated to the county, state or regional level as per users need and downloaded in tabular, graphical, and map formats.
