    Full Text Available Sustainable support for educational development using new technologies in higher education depends on having a basic roadmap that links current demands for developmental support to a plan for ways in which longer term needs will be recognized and met. The growing demand for lifelong learning of a second language is evident within the workplace where new technologies offer flexible solutions. In order to meet the special needs of working adults, the University of Siena Language Center (CLA has developed a multiple-level series of blended English courses from beginner to intermediate level for both university technical-administrative personnel and the hospital staff of the Azienda Ospedaliera Universitaria Senese (AOUS. The pedagogical approach takes into consideration both the needs of adults who are working full-time and the aims of the curriculum, which are to develop the four linguistic abilities of reading, writing, listening and speaking up to the Common European Framework of Reference (CEFR Level B1. Taking into consideration a constructive use of both teaching hours and classrooms, as well as the limited time available to adult learners, a blended approach was chosen. The face-to-face (f2f lessons provide activities concentrating on the development of speaking and listening skills. The online lessons provide a collaborative workspace for interaction in the second language and present a flexible solution for working adults who can structure their study time when and where it is most convenient. This paper will attempt to draw several conclusions regarding the effectiveness of blending approaches for lifelong learning of a second language based on both learner and teacher interviews as well as quantitative and qualitative data collection through questionnaires and end of course evaluation.

    Collaborative cognition research has demonstrated that social partners can positively impact individuals' thinking and problem-solving performance. Research in adulthood and aging has been less clear about dyadic effects, such as partner gender, on collaborative cognition. The current study examined the objective and subjective experiences of older men and women's collaboration on three everyday problems. Tasks included comprehension of everyday printed materials, a social dilemma task, and an errand-planning task. A sample of 98 older married couples (N = 196) worked both collaboratively and individually with either their spouse (N = 52 dyads) or a stranger of the other gender (N = 46 dyads). Analyses conducted using the actor-partner methodology (e.g., Gonzalez & Griffin, 1997; Kenny, 1996) suggest that men tended to be more influential during dyadic problem solving, particularly on more ambiguous tasks. Subjective appraisals of collaboration also varied between male and female partners, with familiarity of partner playing a large role in expectations of collaboration. Most notably, women assigned to work with an unfamiliar male partner tended to rate their satisfaction with collaborative teamwork less positively. Both self and partner-rated subjective appraisals, particularly expectations of competitiveness, were predictive of collaborative performance. PMID:20657668

    Full Text Available BACKGROUND: Cost-Effectiveness Analysis (CEA has been promoted as an important research methodology for determining the efficiency of healthcare technology and guiding medical decision-making. Our aim was to characterize the collaborative patterns of CEA conducted over the past two decades in Spain. METHODS AND FINDINGS: A systematic analysis was carried out with the information obtained through an updated comprehensive literature review and from reports of health technology assessment agencies. We identified CEAs with outcomes expressed as a time-based summary measure of population health (e.g. quality-adjusted life-years or disability-adjusted life-years, conducted in Spain and published between 1989 and 2011. Networks of coauthorship and institutional collaboration were produced using PAJEK software. One-hundred and thirty-one papers were analyzed, in which 526 authors and 230 institutions participated. The overall signatures per paper index was 5.4. Six major groups (one with 14 members, three with 7 members and two with 6 members were identified. The most prolific authors were generally affiliated with the private-for-profit sector (e.g. consulting firms and the pharmaceutical industry. The private-for-profit sector maintains profuse collaborative networks including public hospitals and academia. Collaboration within the public sector (e.g. healthcare administration and primary care was weak and fragmented. CONCLUSIONS: This empirical analysis reflects critical practices among collaborative networks that contributed substantially to the production of CEA, raises challenges for redesigning future policies and provides a framework for similar analyses in other regions.

  9. Short-term and long-term collaboration benefits on individual recall in younger and older adults

    2011-01-01

    A recent study of younger adults suggests that, compared to repeated individual recall trials, repeated collaborative recall trials produce better individual recall after a short delay (Blumen & Rajaram, 2008). Our study was designed to determine if such collaboration benefits would remain after a one-week delay, in both younger and older adults. Sixty younger (M age = 24.60) and 60 older (M age = 67.35) adults studied a list of words and then completed either two collaborative recall trials ...

    Agencies with different foci (e.g. nutrition, social, medical, housing) serve people living with HIV (PLHIV). Serving needs of PLHIV comprehensively requires a high degree of coordination among agencies which often benefits from more frequent communication. We combined Social Network theory and Relational Coordination theory to study coordination among HIV agencies in Baltimore. Social Network theory implies that actors (e.g., HIV agencies) establish linkages amongst themselves in order to access resources (e.g., information). Relational Coordination theory suggests that high quality coordination among agencies or teams relies on the seven dimensions of frequency, timeliness and accuracy of communication, problem-solving communication, knowledge of agencies' work, mutual respect and shared goals. We collected data on frequency of contact from 57 agencies using a roster method. Response options were ordinal ranging from 'not at all' to 'daily'. We analyzed data using social network measures. Next, we selected agencies with which at least one-third of the sample reported monthly or more frequent interaction. This yielded 11 agencies whom we surveyed on seven relational coordination dimensions with questions scored on a Likert scale of 1-5. Network density, defined as the proportion of existing connections to all possible connections, was 20% when considering monthly or higher interaction. Relational coordination scores from individual agencies to others ranged between 1.17 and 5.00 (maximum possible score 5). The average scores for different dimensions across all agencies ranged between 3.30 and 4.00. Shared goals (4.00) and mutual respect (3.91) scores were highest, while scores such as knowledge of each other's work and problem-solving communication were relatively lower. Combining theoretically driven analyses in this manner offers an innovative way to provide a comprehensive picture of inter-agency coordination and the quality of exchange that underlies

  16. A Conceptual Model for Analysing Collaborative Work and Products in Groupware Systems

    Science.gov (United States)

    Duque, Rafael; Bravo, Crescencio; Ortega, Manuel

    Collaborative work using groupware systems is a dynamic process in which many tasks, in different application domains, are carried out. Currently, one of the biggest challenges in the field of CSCW (Computer-Supported Cooperative Work) research is to establish conceptual models which allow for the analysis of collaborative activities and their resulting products. In this article, we propose an ontology that conceptualizes the required elements which enable an analysis to infer a set of analysis indicators, thus evaluating both the individual and group work and the artefacts which are produced.

    High-throughput data production technologies, particularly 'next-generation' DNA sequencing, have ushered in widespread and disruptive changes to biomedical research. Making sense of the large datasets produced by these technologies requires sophisticated statistical and computational methods, as well as substantial computational power. This has led to an acute crisis in life sciences, as researchers without informatics training attempt to perform computation-dependent analyses. Since 2005, the Galaxy project has worked to address this problem by providing a framework that makes advanced computational tools usable by non experts. Galaxy seeks to make data-intensive research more accessible, transparent and reproducible by providing a Web-based environment in which users can perform computational analyses and have all of the details automatically tracked for later inspection, publication, or reuse. In this report we highlight recently added features enabling biomedical analyses on a large scale. PMID:27137889

    Objective Persons with serious mental illness frequently receive inadequate medical care and are more likely to experience difficulty navigating the health care system compared with the general population. To address this gap in quality, we developed a program of peer co-led collaborative activation training for primary care (CAT-PC) designed to improve “patient activation” and person-centered care in primary care visits for middle-aged and older adults with serious mental illness and cardiovascular risk. This report presents pilot study feasibility and participant outcomes for CAT-PC. Method A pre-post pilot evaluation of CAT-PC included N = 17 adults (age ≥ 50) with serious mental illness and cardiovascular health risk conditions, and N = 6 primary care providers. CAT-PC consists of 9 weekly peer co-led patient education and skills training sessions and a 45-min video-based training for primary care providers. Pre-post measures included the Patient Activation Measure (PAM), Perceived Efficacy in Patient-Physician Interactions (PEPPI), Autonomy Preference Index (API) for preferred role in primary care encounters, and Social Skills Performance Assessment (SSPA) role-play test for medical visits. Results All 17 participants attended 5 or more sessions. Post-intervention improvement was found for patient activation and simulated performance of medical visit communication skills. Trends were observed for improved self-efficacy in provider interactions and greater preference for a more collaborative role in decision-making. Conclusions and Implications CAT-PC is a brief, peer co-led education and skills training intervention potentially improving patient activation in primary care encounters and providing an important missing component in emerging models of “patient-centered behavioral health homes” for this high-risk group.

    The Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) Consortium is a collaborative network of researchers working together on a range of large-scale studies that integrate data from 70 institutions worldwide. Organized into Working Groups that tackle questions in neuroscience, genetics, and medicine, ENIGMA studies have analyzed neuroimaging data from over 12,826 subjects. In addition, data from 12,171 individuals were provided by the CHARGE consortium for replication of findings, in a total of 24,997 subjects. By meta-analyzing results from many sites, ENIGMA has detected factors that affect the brain that no individual site could detect on its own, and that require larger numbers of subjects than any individual neuroimaging study has currently collected. ENIGMA's first project was a genome-wide association study identifying common variants in the genome associated with hippocampal volume or intracranial volume. Continuing work is exploring genetic associations with subcortical volumes (ENIGMA2) and white matter microstructure (ENIGMA-DTI). Working groups also focus on understanding how schizophrenia, bipolar illness, major depression and attention deficit/hyperactivity disorder (ADHD) affect the brain. We review the current progress of the ENIGMA Consortium, along with challenges and unexpected discoveries made on the way. PMID:24399358

    It is acknowledged internationally that chronic disease management (CDM) for community-living older adults (CLOA) is an increasingly complex process. CDM for older adults, who are often living with multiple chronic conditions, requires coordination of various health and social services. Coordination is enabled through interprofessional collaboration (IPC) among individual providers, community organizations, and health sectors. Measuring IPC is complicated given there are multiple conceptualisations and measures of IPC. A literature review of several healthcare, psychological, and social science electronic databases was conducted to locate instruments that measure IPC at the team level and have published evidence of their reliability and validity. Five instruments met the criteria and were critically reviewed to determine their strengths and limitations as they relate to CDM for CLOA. A comparison of the characteristics, psychometric properties, and overall concordance of each instrument with salient attributes of IPC found the Collaborative Practice Assessment Tool to be the most appropriate instrument for measuring IPC for CDM in CLOA.

    AOAC First Action Method 2011.18, Myo-Inositol (Free and Bound as Phosphatidylinositol) in Infant and Pediatric Formulas and Adult Nutritionals, was collaboratively studied. With this method free myo-inositol and phosphatidylinositol bound myo-inositol are extracted using two different sample preparation procedures, separated by ion chromatography using a combination of Dionex Carbo Pac PA1 and MA1 columns with column switching, and detected with pulsed amperometry using a gold electrode. Free myo-inositol is extracted from samples with dilute hydrochloric acid and water. Phosphatidylinositol is extracted from samples with chloroform and separated from other fats with silica SPE cartridges. Myo-inositol is then released from the glycerol backbone with concentrated acetic and hydrochloric acids at 120°C. During this collaborative study, nine laboratories from five different countries analyzed blind duplicates of nine infant and pediatric nutritional formulas for both free and phosphatidylinositol bound myo-inositol, and one additional laboratory only completed the free myo-inositol analyses. The method demonstrated acceptable repeatability and reproducibility and met the AOAC Stakeholder Panel on Infant Formula and Adult Nutritionals (SPIFAN) Standard Method Performance Requirements (SMPRs®) for free myo-inositol plus phosphatidylinositol bound myo-inositol for all the matrixes analyzed. SMPRs for repeatability were ≤5% RSD at myo-inositol concentrations of 2-68 mg/100 g ready-to-feed (RTF) liquid. SMPRs for reproducibility were ≤8% RSD in products with myo-inositol concentrations ranging from 2 to 68 mg/100 g RTF liquid. During this collaborative study, repeatability RSDs ranged from 0.51 to 3.22%, and RSDs ranged from 2.66 to 7.55% for free myo-inositol plus phosphatidylinositol bound myo-inositol. PMID:26651580

    Objective To investigate vilazodone, currently approved for major depressive disorder in adults, for generalized anxiety disorder (GAD). Method Three randomized, double-blind, placebo-controlled studies showing positive results for vilazodone (2,040 mg/d) in adult patients with GAD (DSM-IV-TR) were pooled for analyses; data were collected from June 2012 to March 2014. Post hoc outcomes in the pooled intent-to-treat population (n = 1,462) included mean change from baseline to week 8 in Hamilton Anxiety Rating Scale (HARS) total score, psychic and somatic anxiety subscale scores, and individual item scores; HARS response (≥ 50% total score improvement) and remission (total score ≤ 7) at week 8; and category shifts, defined as HARS item score ≥ 2 at baseline (moderate to very severe symptoms) and score of 0 at week 8 (no symptoms). Results The least squares mean difference was statistically significant for vilazodone versus placebo in change from baseline to week 8 in HARS total score (−1.83, P anxiety (−1.21, P anxiety (−0.63, P < .01) subscale scores; differences from placebo were significant on 11 of 14 HARS items (P < .05). Response rates were higher with vilazodone than placebo (48% vs 39%, P < .001), as were remission rates (27% vs 21%, P < .01). The percentage of patients who shifted to no symptoms was significant for vilazodone on several items: anxious mood, tension, intellectual, depressed mood, somatic-muscular, somatic-sensory, cardiovascular, respiratory, and autonomic symptoms (P < .05). Conclusions Treatment with vilazodone versus placebo was effective in adult GAD patients, with significant differences between treatment groups found on both psychic and somatic HARS items. Trial Registration ClinicalTrials.gov identifiers: NCT01629966, NCT01766401, NCT01844115.

    Full Text Available Numerous software implements Dynamic Geometry since the 80s. Some of them introduce functionalities of synchronous communication allowing distant exchanges of geometric contents. Even if the availability of such functionalities is very important, it doesn’t guaranty collaboration or learning between the partners of exchanges: the conception and conduct of collaborative learning situations is a key issue. It’s in this sense that we are interested in studying, through the instrumental orchestration, what three of these software (Geogebra, Tabulae and Compass and Ruler are offering for supporting conception and conduct of collaborative learning situations, beyond the functionalities for the synchronous communication of geometric contents.

A total of 695 adults including 259 healthy volunteers and 436 CKD patients were recruited. Participants from the Kaohsiung Medical University Hospital were used as the development set (N = 556 to develop the Taiwanese eGFR equations, whereas participants from the National Taiwan University Hospital were used as the validation set (N = 139 for external validation.The Taiwanese eGFR equations were developed by using the extended Bland-Altman plot in the development set. The Taiwanese MDRD equation was 1.309 × MDRD0.912, Taiwanese CKD-EPI was 1.262×CKD-EPI0.914 and Taiwanese four-level CKD-EPI was 1.205 × four-level CKD-EPI0.914. In the validation set, the Taiwanese equations had the lowest bias, the Taiwanese equations and the Japanese CKD-EPI equation had the lowest RMSE, whereas the Taiwanese and the Japanese equations had the best precision and the highest P30 among all equations. However, the Taiwanese MDRD equation had higher concordance correlation than did the Taiwanese CKD-EPI, the Taiwanese four-level CKD-EPI and the Japanese equations. Moreover, only the Taiwanese equations had no proportional bias among all of the equations. Finally, the Taiwanese MDRD equation had the best diagnostic performance in terms of ordinal logistic regression among all of the equations.The Taiwanese MDRD equation is better than the MDRD, CKD-EPI, Japanese, Asian, Thai, Taiwanese CKD-EPI, and Taiwanese four-level CKD-EPI equations for Taiwanese adults.

    2016-09-01

    Everyday memory lapses experienced by older adults (OAs) were examined using a daily-diary checklist and retrospective questionnaire. In Experiment 1, 138 younger and 138 OAs indicated the frequency of forgetting of 16 memory lapses, and whether each occurred daily during the course of a week. OAs reported more memory lapses on the questionnaire, but not the daily diary. OAs reported more frequently forgetting names and words, while younger adults had more difficulty with appointments and personal dates. Fewer memory lapses on the daily diary were related to better performance on a laboratory-memory measure for OAs. In Experiment 2, 62 OAs returned for a five-year follow-up and endorsed experiencing more memory lapses on the daily diary compared to baseline, specifically forgetting more names and words, but not the retrospective questionnaire. Daily checklist memory lapses again correlated with the laboratory-memory measure. A daily checklist may be a viable way to assess everyday memory lapses. PMID:26810777

    The cattle tick, Rhipicephalus microplus, has a debilitating effect on the livestock industry worldwide, owing to its being a vector of the causative agents of bovine babesiosis and anaplasmosis. In South Africa, co-infestation with R. microplus and R. decoloratus, a common vector species on local livestock, occurs widely in the northern and eastern parts of the country. An alternative to chemical control methods is sought in the form of a tick vaccine to control these tick species. However, sequence information and transcriptional data for R. decoloratus is currently lacking. Therefore, this study aimed at identifying genes that are shared between midgut tissues of feeding adult female R. microplus and R. decoloratus ticks. In this regard, a custom oligonucleotide microarray comprising of 13,477 R. microplus sequences was used for transcriptional profiling and 2476 genes were found to be shared between these Rhipicephalus species. In addition, 136 transcripts were found to be more abundantly expressed in R. decoloratus and 1084 in R. microplus. Chi-square analysis revealed that genes involved in lipid transport and metabolism are significantly overrepresented in R. microplus and R. decoloratus. This study is the first transcriptional profiling of R. decoloratus and is an additional resource that can be evaluated further in future studies for possible tick control. PMID:25448423

    Full Text Available Poor health-related quality-of-life (HRQOL is a significant public health issue while the use of meditative movement therapies has been increasing. The purpose of this investigation was to carry out a systematic review of previous meta-analyses that examined the effects of meditative movement therapies (yoga, tai chi and qigong on HRQOL in adults. Previous meta-analyses of randomized controlled trials published up through February, 2014 were included by searching nine electronic databases and cross-referencing. Dual-selection and data abstraction occurred. The Assessment of Multiple Systematic Reviews Instrument (AMSTAR was used to assess methodological quality. Standardized mean differences that were pooled using random-effects models were included. In addition, 95% prediction intervals were calculated as well as the number needed-to-treat and percentile improvements.

    Poor health-related quality-of-life (HRQOL) is a significant public health issue while the use of meditative movement therapies has been increasing. The purpose of this investigation was to carry out a systematic review of previous meta-analyses that examined the effects of meditative movement therapies (yoga, tai chi and qigong) on HRQOL in adults. Previous meta-analyses of randomized controlled trials published up through February, 2014 were included by searching nine electronic databases and cross-referencing. Dual-selection and data abstraction occurred. The Assessment of Multiple Systematic Reviews Instrument (AMSTAR) was used to assess methodological quality. Standardized mean differences that were pooled using random-effects models were included. In addition, 95% prediction intervals were calculated as well as the number needed-to-treat and percentile improvements. Of the 510 citations screened, 10 meta-analyses representing a median of 3 standardized mean differences in 82 to 528 participants (median = 270) with breast cancer, schizophrenia, low back pain, heart failure and diabetes, were included. Median methodological quality was 70%. Median length, frequency and duration of the meditative movement therapies were 12 weeks, 3 times per week, for 71 minutes per session. The majority of results (78.9%) favored statistically significant improvements (non-overlapping 95% confidence intervals) in HRQOL, with standardized mean differences ranging from 0.18 to 2.28. More than half of the results yielded statistically significant heterogeneity (Q ≤ 0.10) and large or very large inconsistency (I2 ≥ 50%). All 95% prediction intervals included zero.

    Full Text Available The gastric pathogen Helicobacter pylori is one of the most genetically diverse of bacterial species. Much of its diversity stems from frequent mutation and recombination, preferential transmission within families and local communities, and selection during persistent gastric mucosal infection. MLST of seven housekeeping genes had identified multiple distinct H. pylori populations, including three from Africa: hpNEAfrica, hpAfrica1 and hpAfrica2, which consists of three subpopulations (hspWAfrica, hspCAfrica and hspSAfrica. Most detailed H. pylori population analyses have used strains from non-African countries, despite Africa's high importance in the emergence and evolution of humans and their pathogens. Our concatenated sequences from seven H. pylori housekeeping genes from 44 Gambian patients (MLST identified 42 distinct sequence types (or haplotypes, and no clustering with age or disease. STRUCTURE analysis of the sequence data indicated that Gambian H. pylori strains belong to the hspWAfrica subpopulation of hpAfrica1, in accord with Gambia's West African location. Despite Gambia's history of invasion and colonisation by Europeans and North Africans during the last millennium, no traces of Ancestral Europe1 (AE1 population carried by those people were found. Instead, admixture of 17% from Ancestral Europe2 (AE2 was detected in Gambian strains; this population predominates in Nilo-Saharan speakers of North-East Africa, and might have been derived from admixture of hpNEAfrica strains these people carried when they migrated across the Sahara during the Holocene humid period 6,000-9,000 years ago. Alternatively, shared AE2 ancestry might have resulted from shared ancestral polymorphisms already present in the common ancestor of sister populations hpAfrica1 and hpNEAfrica.

    Full Text Available Abstract Background Epidemiological research into the role of traffic pollution on chronic respiratory and allergic disease has focused primarily on children. Studies in adults, in particular those based on objective outcomes such as bronchial hyperresponsiveness, skin sensitisation, and lung function, are limited. Methods We have used an existing cohort of 2644 adults aged 18–70 living in Nottingham, UK, for whom baseline health and demographic data were collected in 1991 and computed two markers of exposure to traffic: distance between the home and nearest main road and modelled outdoor nitrogen dioxide (NO2 concentration at the home location. Using multiple regression techniques, we analysed cross-sectional associations with bronchial hyperresponsiveness, FEV1, spirometry-defined COPD, skin test positivity, total IgE and questionnaire-reported wheeze, asthma, eczema and hayfever in 2599 subjects, and longitudinal associations with decline in FEV1 in 1329 subjects followed-up nine years later in 2000. Results There were no significant cross-sectional associations between home proximity to the roadside or NO2 level on any of the outcomes studied (adjusted OR of bronchial hyperresponsiveness in relation to living ≤150 m vs >150 m from a road = 0.92, 95% CI 0.68 to 1.24. Furthermore, neither exposure was associated with a significantly greater decline in FEV1 over time (adjusted mean difference in ΔFEV1 for living ≤150 m vs >150 m of a road = 10.03 ml, 95% CI, -33.98 to 54.04. Conclusion This study found no evidence to suggest that living in close proximity to traffic is a major determinant of asthma, allergic disease or COPD in adults.

    interdisciplinary collaboration. The question here is how to combine policy science frameworks (e.g. the Advocacy Coalition Framework) and social network methods (e.g. Social Network Analysis) with frameworks that allow a connection with the physical delta systems. This will result in a new framework for analysing interdisciplinary stakeholder coalitions, evolution and learning in strategic delta planning. The use of this framework will be illustrated with an example from strategic delta planning in the Dutch Southwest Delta. With this, we want to see how spatial planning and water management disciplines have combined into new policies for delta management in the Netherlands over the past 25 years.

    AOAC First Action Method 2011.10, Vitamin B12 in Infant and Pediatric Formulas and Adult Nutritionals, was collaboratively studied. This method uses a pH 4.5 sodium acetate buffer and potassium cyanide at 105°C to extract and convert all biologically active forms of vitamin B12 present to cyanocobalamin; octylsilyl (C8) or C18 SPE cartridges to purify and concentrate cyanocobalamin; a combination of size-exclusion and RPLC to isolate cyanocobalamin; and visible absorbance at 550 nm to detect and quantitate cyanocobalamin in infant, pediatric, and adult nutritionals with vitamin B12 concentrations greater than 0.025 μg/100 g ready-to-feed (RTF) liquid. During this collaborative study, nine to 11 laboratories from eight different countries analyzed blind duplicates of 12 infant, pediatric, and adult nutritional formulas. Per the AOAC Expert Review Panel (ERP) on Stakeholder Panel on Infant Formula and Adult Nutritionals (SPIFAN) Nutrient Methods the method demonstrated acceptable repeatability and reproducibility and met SPIFAN Standard Method Performance Requirements (SMPRs®) for the majority of product matrixes analyzed. Vitamin B12 SPIFAN SMPRs for repeatability were ≤15% RSD at vitamin B12 concentrations of 0.01 μg/100 g RTF liquid and ≤7% RSD at vitamin B12 concentrations of 0.2-5.0 μg/100 g RTF liquid. Vitamin B12 SPIFAN SMPRs for reproducibility were ≤11% RSD in products with vitamin B12 concentrations ranging from 0.3 to 5.0 μg/100 g RTF liquid. During this collaborative study, the RSDr ranged from 2.98 to 9.77%, and the RSDR ranged from 3.54 to 19.5%. During previous single-laboratory validation studies, the method LOQ was estimated to be 0.025 μg/100 g RTF liquid. PMID:26651579

    2013-01-01

    Full Text Available Abstract Background Low back pain is a prevalent and debilitating condition that affects the health and quality of life of older adults. Older people often consult primary care physicians about back pain, with many also receiving concurrent care from complementary and alternative medicine providers, most commonly doctors of chiropractic. However, a collaborative model of treatment coordination between these two provider groups has yet to be tested. The primary aim of the Collaborative Care for Older Adults Clinical Trial is to develop and evaluate the clinical effectiveness and feasibility of a patient-centered, collaborative care model with family medicine physicians and doctors of chiropractic for the treatment of low back pain in older adults. Methods/design This pragmatic, pilot randomized controlled trial will enroll 120 participants, age 65 years or older with subacute or chronic low back pain lasting at least one month, from a community-based sample in the Quad-Cities, Iowa/Illinois, USA. Eligible participants are allocated in a 1:1:1 ratio to receive 12 weeks of medical care, concurrent medical and chiropractic care, or collaborative medical and chiropractic care. Primary outcomes are self-rated back pain and disability. Secondary outcomes include general and functional health status, symptom bothersomeness, expectations for treatment effectiveness and improvement, fear avoidance behaviors, depression, anxiety, satisfaction, medication use and health care utilization. Treatment safety and adverse events also are monitored. Participant-rated outcome measures are collected via self-reported questionnaires and computer-assisted telephone interviews at baseline, and at 4, 8, 12, 24, 36 and 52 weeks post-randomization. Provider-rated expectations for treatment effectiveness and participant improvement also are evaluated. Process outcomes are assessed through qualitative interviews with study participants and research clinicians, chart audits

  9. Preoperative mapping of cortical language areas in adult brain tumour patients using PET and individual non-normalised SPM analyses

    International Nuclear Information System (INIS)

    In patients scheduled for the resection of perisylvian brain tumours, knowledge of the cortical topography of language functions is crucial in order to avoid neurological deficits. We investigated the applicability of statistical parametric mapping (SPM) without stereotactic normalisation for individual preoperative language function brain mapping using positron emission tomography (PET). Seven right-handed adult patients with left-sided brain tumours (six frontal and one temporal) underwent 12 oxygen-15 labelled water PET scans during overt verb generation and rest. Individual activation maps were calculated for P<0.005 and P<0.001 without anatomical normalisation and overlaid onto the individuals' magnetic resonance images for preoperative planning. Activations corresponding to Broca's and Wernicke's areas were found in five and six cases, respectively, for P<0.005 and in three and six cases, respectively, for P<0.001. One patient with a glioma located in the classical Broca's area without aphasic symptoms presented an activation of the adjacent inferior frontal cortex and of a right-sided area homologous to Broca's area. Four additional patients with left frontal tumours also presented activations of the right-sided Broca's homologue; two of these showed aphasic symptoms and two only a weak or no activation of Broca's area. Other frequently observed activations included bilaterally the superior temporal gyri, prefrontal cortices, anterior insulae, motor areas and the cerebellum. The middle and inferior temporal gyri were activated predominantly on the left. An SPM group analysis (P<0.05, corrected) in patients with left frontal tumours confirmed the activation pattern shown by the individual analyses. We conclude that SPM analyses without stereotactic normalisation offer a promising alternative for analysing individual preoperative language function brain mapping studies. The observed right frontal activations agree with proposed reorganisation processes, but

    Wenbo Tang

    Full Text Available Genome-wide association studies (GWAS have identified numerous loci influencing cross-sectional lung function, but less is known about genes influencing longitudinal change in lung function.We performed GWAS of the rate of change in forced expiratory volume in the first second (FEV1 in 14 longitudinal, population-based cohort studies comprising 27,249 adults of European ancestry using linear mixed effects model and combined cohort-specific results using fixed effect meta-analysis to identify novel genetic loci associated with longitudinal change in lung function. Gene expression analyses were subsequently performed for identified genetic loci. As a secondary aim, we estimated the mean rate of decline in FEV1 by smoking pattern, irrespective of genotypes, across these 14 studies using meta-analysis.The overall meta-analysis produced suggestive evidence for association at the novel IL16/STARD5/TMC3 locus on chromosome 15 (P  =  5.71 × 10(-7. In addition, meta-analysis using the five cohorts with ≥3 FEV1 measurements per participant identified the novel ME3 locus on chromosome 11 (P  =  2.18 × 10(-8 at genome-wide significance. Neither locus was associated with FEV1 decline in two additional cohort studies. We confirmed gene expression of IL16, STARD5, and ME3 in multiple lung tissues. Publicly available microarray data confirmed differential expression of all three genes in lung samples from COPD patients compared with controls. Irrespective of genotypes, the combined estimate for FEV1 decline was 26.9, 29.2 and 35.7 mL/year in never, former, and persistent smokers, respectively.In this large-scale GWAS, we identified two novel genetic loci in association with the rate of change in FEV1 that harbor candidate genes with biologically plausible functional links to lung function.

    2013-09-01

    Full Text Available Objectives: Early childhood physical growth may have an impact on the development of adult mental distress. The primary objectives were to (1 assess the association of early growth in weight (adjusted for height with adult mental distress, and (2 determine if specific sub-types, or patterns, of early physical growth are associated with adult mental distress.Methods: Subjects were all Johns Hopkins Collaborative Perinatal Study cohort subjects with complete birth size information that successfully completed the Pathways to Adulthood follow-up in early adulthood. Variability in the timing of growth in weight adjusted for height from birth to age 7.5 years was taken into account using a nonhierarchical linear model. Two critical periods of growth were considered as tertiles of change in weight adjusted for height from birth to age seven and birth to age 1 year. Mental distress in adulthood (ages 29-32 was measured using the General Health Questionnaire (GHQ-28.Results: Small for gestational age subjects were at increased risk of later mental distress, but not uniformly so. Those born with low weight and length for gestational age were a distinct subgroup of those born small for gestational age, and had unique patterns of risk for adult mental distress when early growth was considered.Conclusions: Acceleration and deceleration in weight for height change is associated with mental distress over multiple periods of early life and acts differentially between those periods. Furthermore, the association of early childhood growth with the likelihood of adult mental distress is dependent on prenatal growth.

    Awareness of the need for collaboration across pediatric and adult cancer to care for adolescents and young adults (AYAs) arose from the recognition of the unique characteristics of AYAs with cancer. Neither pediatric nor adult oncology hospital departments are able to provide age-appropriate care single handedly. The best way to bridge the gap in care of AYA cancer patients is to centralize aspects of their care within dedicated AYA care programs, including the following essential components: provision of developmentally appropriate and multidisciplinary (supportive) care, availability of AYA inpatient and outpatient facilities and healthcare professional AYA expertise as collaboration between adult and pediatric departments. Barriers are related to the slowly emerging evidence of benefit, cultural differences (collaboration between pediatric and adult oncology professionals), administrative and logistic challenges (small number of AYAs makes it difficult to create an AYA program in every hospital) and financial aspects (dependency on philanthropic funds). The sustainable development of an AYA program requires acceptance as a standard of care at the clinical and patient community and at government level. To improve the quality, equity and quantity of research and innovation in AYA cancer care across the world, it is necessary to join forces and collaborate in international networks to study issues such as the features of quality care, collaboration between pediatric and adult clinical teams, trial groups and professional societies, and AYA-specific groups such as Critical Mass, Canteen or European Network for Teenagers and Young Adults with Cancer.

    2016-01-01

    A collaborative study was conducted on AOAC First Action Method 2012.13 "Determination of Labeled Fatty Acids Content in Milk Products and Infant Formula by Capillary Gas Chromatography," which is based on an initial International Organization for Standardization (ISO)-International Dairy Federation (IDF) New Work Item that has been moved forward to ISO 16958:2015|IDF 231:2015 in November 2015. It was decided to merge the two activities after the agreement signed between ISO and AOAC in June 2012 to develop common standards and to avoid duplicate work. The collaborative study was performed after having provided highly satisfactory single-laboratory validation results [Golay, P.A., & Dong, Y. (2015) J. AOAC Int. 98, 1679-1696] that exceeded the performance criteria defined in AOAC Standard Method Performance Requirement (SMPR(®)) 2012.011 (September 29, 2012) on 12 products selected by the AOAC Stakeholder Panel on Infant Formula (SPIFAN). After a qualification period of 1 month, 18 laboratories participated in the fatty acids analysis of 12 different samples in duplicate. Six samples were selected to meet AOAC SPIFAN requirements (i.e., infant formula and adult nutritionals in powder and liquid formats), and the other Six samples were selected to meet ISO-IDF requirements (i.e., dairy products such as milk powder, liquid milk, cream, butter, infant formula with milk, and cheese). The fatty acids were analyzed directly in all samples without preliminary fat extraction, except in one sample (cheese). Powdered samples were analyzed after dissolution (i.e., reconstitution) in water, whereas liquid samples (or extracted fat) were analyzed directly. After addition of the internal standards solution [C11:0 fatty acid methyl ester (FAME) and C13:0 triacylglycerols (TAG)] to the samples, fatty acids attached to lipids were transformed into FAMEs by direct transesterification using methanolic sodium methoxide. FAMEs were separated using highly polar capillary GLC and were

Six adult male cats (Felix catus), with 12 h day-light cycle and ad libitum water and food regimen, received a single dose of MeHgCl (6.4 mg/kg) dissolved in milk, whereas control subjects (n=6) received only milk. After 30 days, biocytin iontophoretic injections were done into the area 17, (Horsley-Clark coordinates between AP 3.0-6.0) on the crown of the lateral gyrus, near the border with area 18. MeHg and inorganic Hg (Hgi) concentrations were measured in the brain parenchyma of intoxicated cats and corresponded on average to 1.39+/-0.3 and 6.79+/-0.6 ppm (mean+/-s.e.m.) respectively. Twenty four hours after iontophoresis, aldehyde fixed brain sections (200 microm thick), were processed to reveal biocytin labeled terminals. Axonal microscopic 3D reconstructions using Neurolucida software (Microbright Systems Inc.) allowed estimations of boutons, branching points and segment densities for each terminal. Cluster analysis of morphometric axonal features from control and intoxicated group revealed, two distinct axon families (Type I and II) as described elsewhere. Total density values of boutons, branching points and segment densities of intoxicated group, decreased 81, 59 and 91% respectively, as compared to the control group (ANOVA two-way, Bonferroni a priori test pintoxication in the visual cortex.

    Full Text Available BACKGROUND: The risk of malignancies on TNF-α antagonists is controversial. The aim of this survey was to assess cancer risk on TNF-α antagonists in adult rheumatoid arthritis patients, including the five marketed drugs (infliximab, etanercept, adalimumab, golimumab and certolizumab used in line with the New Drug Application. Furthermore, the relative interest of modified intention to treat or per protocol analyses to assess such sparse events remains unknown. METHODOLOGY/PRINCIPAL FINDINGS: Data sources were MEDLINE, CENTRAL, ISI Web of Science, ACR and EULAR meeting abstracts, scientific evaluation of the drugs leading to their marketing approval, and clinicaltrials.gov, until 31 December 2012.We selected double-blind randomized controlled trials in adult rheumatoid arthritis patients, including at least one treatment arm in line with New Drug Application. We performed random effect meta-analysis, with modified intention to treat and per protocol analyses. Thirty-three trials were included. There was no excess risk of malignancies on anti-TNF-α administered in line with New Drug Application in the per protocol model (OR, 0.93 95%CI[0.59-1.44], as well as in the modified intention to treat model (OR, 1.27 95%CI[0.82-1.98]. There was a non-significant tendency for an excess non-melanoma skin cancer risk in both models (respectively, 1.37 [0.71-2.66] and 1.90 [0.98-3.67]. With fixed effect Peto model restricting to trials during at least 52 weeks, the overall cancer risk was respectively 1.60 [0.97-2.64] and 1.22 [0.72-2.08]. Whatever the model, modified intention to treat analysis led to higher estimations than per protocol analysis. The later may underestimate the treatment effect when assessing very sparse events and when many patients dropped out in placebo arms. In metaregression, there was no differential risk among the five drugs. CONCLUSIONS/SIGNIFICANCE: This study did not find any evidence for an excess cancer risk on TNF

  8. Resurrecting Brinley Plots for a Novel Use: Meta-Analyses of Functional Brain Imaging Data in Older Adults

    2008-01-01

    Full Text Available By plotting response times of young and older adults across a variety of tasks, Brinley spurred investigation and debate into the theory of general cognitive slowing. Though controversial, Brinley plots can assess between-task differences, the impact of increasing task demand, and the relationship between responses in two groups of subjects. Since a relationship exists between response times and the blood-oxygen level dependent (BOLD signal of functional MRI (fMRI, Brinley's plotting method could be applied as a meta-analysis tool in fMRI studies of aging. Here, fledgling “Peiffer plots” are discussed for their potential impact on understanding general cognitive brain activity in aging. Preliminary results suggest that general cognitive slowing may be localized at the sensorimotor transformation in the precentral gyrus. Although this meta-analysis method is naturally used with imaging studies of aging, theoretically it may be applied to other study pairs (e.g., schizophrenic versus normal or imaging datasets (e.g., PET.

  9. 2H NMR and 13C-IRMS analyses of acetic acid from vinegar, 18O-IRMS analysis of water in vinegar: International collaborative study report

    International Nuclear Information System (INIS)

    An international collaborative study of isotopic methods applied to control the authenticity of vinegar was organized in order to support the recognition of these procedures as official methods. The determination of the 2H/1H ratio of the methyl site of acetic acid by SNIF-NMR (site-specific natural isotopic fractionation-nuclear magnetic resonance) and the determination of the 13C/12C ratio, by IRMS (isotope ratio mass spectrometry) provide complementary information to characterize the botanical origin of acetic acid and to detect adulterations of vinegar using synthetic acetic acid. Both methods use the same initial steps to recover pure acetic acid from vinegar. In the case of wine vinegar, the determination of the 18O/16O ratio of water by IRMS allows to differentiate wine vinegar from vinegars made from dried grapes. The same set of vinegar samples was used to validate these three determinations. The precision parameters of the method for measuring δ13C (carbon isotopic deviation) were found to be similar to the values previously obtained for similar methods applied to wine ethanol or sugars extracted from fruit juices: the average repeatability (r) was 0.45 per mille , and the average reproducibility (R) was 0.91 per mille . As expected from previous in-house study of the uncertainties, the precision parameters of the method for measuring the 2H/1H ratio of the methyl site were found to be slightly higher than the values previously obtained for similar methods applied to wine ethanol or fermentation ethanol in fruit juices: the average repeatability was 1.34 ppm, and the average reproducibility was 1.62 ppm. This precision is still significantly smaller than the differences between various acetic acid sources (δ13C and δ18O) and allows a satisfactory discrimination of vinegar types. The precision parameters of the method for measuring δ18O were found to be similar to the values previously obtained for other methods applied to wine and fruit juices: the

    Two experiments examine how collaboration influences visual search performance. Working with a partner or on their own, participants reported whether a target was present or absent in briefly presented search displays. We compared the search performance of individuals working together (collaborative pairs) with the pooled responses of the individuals working alone (nominal pairs). Collaborative pairs were less likely than nominal pairs to correctly detect a target and they were less likely to make false alarms. Signal detection analyses revealed that collaborative pairs were more sensitive to the presence of the target and had a more conservative response bias than the nominal pairs. This pattern was observed even when the presence of another individual was matched across pairs. The results are discussed in the context of task-sharing, social loafing and current theories of visual search. PMID:17972737

    Full Text Available Background: Polycystic liver in the adult (PLA is a rare disease characterized by chronic liver enlargement. Objective: To analyse gastroenterologists' involvement in, experience with, and attitude toward diagnosing, monitoring, and treating patients with PLA in Spain. Methods: Each of seven study coordinators contacted 15 specialists in their geographic area about participating in the study via an online structured survey. Results: Of the 105 clinics contacted, 88 completed the questionnaire, with a mean of 3 patients being followed per practice, although 6 clinics were following more than 20 patients with PLA. Patients were being followed mainly by the Department of Hepatology (81 % and/or the Department of Gastroenterology (33 %. The majority of patients were diagnosed (98 % and monitored (97 % using liver ultrasound. When diagnosed, 76 % of patients were under 50 years of age, females predominating. The primary treatment objective for the patients was symptomatic management. Pharmacotherapy was prescribed by 28 % of physicians: Somatostatin analogues, primarily, followed by mTOR inhibitors. One-third of the clinics indicated that they had patients who had undergone liver transplant and/or surgery. Conclusions: Ultrasound is the diagnosing and monitoring method of choice. Among the clinics using pharmacotherapy for symptomatic management, somatostatin analogues were the drugs of choice. These clinics' infrequent use of invasive procedures suggests that they perceive the various invasive techniques as not very effective.

    Glaucoma, the leading cause of irreversible blindness, appears in various forms. Mutations in CYP1B1 result in primary congenital glaucoma (PCG) by an autosomal recessive mode of inheritance while it acts as a modifier locus for primary open angle glaucoma (POAG). We investigated the molecular basis of the variable phenotypes resulting from the defects in CYP1B1 by using subclones of 23 CYP1B1 mutants reported in glaucoma patients, in a cell based system by measuring the dual activity of the enzyme to metabolize both retinol and 17β-estradiol. Most variants linked to POAG showed low steroid metabolism while null or very high retinol metabolism was observed in variants identified in PCG. We examined the translational turnover rates of mutant proteins after the addition of cycloheximide and observed that the levels of enzyme activity mostly corroborated the translational turnover rate. We performed extensive normal mode analysis and molecular-dynamics-simulations-based structural analyses and observed significant variation of fluctuation in certain segmental parts of the mutant proteins, especially at the B-C and F-G loops, which were previously shown to affect the dynamic behavior and ligand entry/exit properties of the cytochrome P450 family of proteins. Our molecular study corroborates the structural analysis, and suggests that the pathologic state of the carrier of CYP1B1 mutations is determined by the allelic state of the gene. To our knowledge, this is the first attempt to dissect biological activities of CYP1B1 for correlation with congenital and adult onset glaucomas. PMID:27243976

    The main objective of the AOAC Stakeholder Panel on Infant Formula and Adult Nutritionals (SPIFAN) project is to establish international consensus methods for infant formula and adult nutritionals, which will benefit intermarket supply and dispute resolution. A collaborative study was conducted on AOAC First Action Method 2012.10 Simultaneous Determination of 13-cis and All-trans Vitamin A Palmitate (Retinyl Palmitate), Vitamin A Acetate (Retinyl Acetate), and Total Vitamin E (α-Tocopherol and D-α-tocopherol acetate) in Infant Formula and Adult Nutritionals by Normal-Phase HPLC. Fifteen laboratories from 11 countries participated in an interlaboratory study to determine 13-cis and all-trans vitamin A palmitate (retinyl palmitate), vitamin A acetate (retinyl acetate), and total vitamin E (α-tocopherol and D-α-tocopherol acetate) in infant formula and adult nutritionals by normal-phase HPLC and all laboratories returned valid data. Eighteen test portions of nine blind duplicates of a variety of infant formula and adult nutritional products were used in the study. The matrixes included milk-based and soy-based hydrolyzed protein as well as a low fat product. Each of the samples was prepared fresh and analyzed in singlicate. As the number of samples exceeded the recommended number to be prepared in a single day, analysis took place over 2 days running 12 samples on day one and 10 samples on day two. The reference standard stock was prepared once and the six-point curve diluted freshly on each day. Results obtained from all 15 laboratories are reported. The RSDR for total vitamin A (palmitate or acetate) ranged from 6.51 to 22.61% and HorRat values ranged from 0.33 to 1.25. The RSDR for total vitamin E (as tocopherol equivalents) ranged from 3.84 to 10.78% and HorRat values ranged from 0.27 to 1.04. Except for an adult low fat matrix which generated reproducibility RSD >40% for some isomers, most SPIFAN matrixes gave results within the acceptance criteria of <16

    A need exists for United States military forces to perform collaborative engagement operations between unmanned systems. This capability has the potential to contribute significant tactical synergy to the Joint Force operating in the battlespace of the future. Collaborative engagements potentially offer force conservation, perform timely acquisition and dissemination of essential combat information, and can eliminate high value and time critical targets. Collaborative engagements can also add considerably to force survivability by reducing soldier and equipment exposure during critical operations. This paper will address a multiphase U.S. Army Aviation and Missile Research, Development, and Engineering Center (AMRDEC) Joint Technology Center (JTC) Systems Integration Laboratory (SIL) program to assess information requirements, Joint Architecure for Unmanned Systems (JAUS), on-going Science and Technology initiatives, and conduct simulation based experiments to identify and resolve technical risks required to conduct collaborative engagements using unmanned aerial vehicles (UAV) and unmanned ground vehicles (UGV). The schedule outlines an initial effort to expand, update and exercise JAUS, provide early feedback to support user development of Concept of Operations (CONOPs) and Tactics, Techniques and Procedures (TTPs), and develop a Multiple Unified Simulation Environment (MUSE) system with JAUS interfaces necessary to support an unmanned system of systems collaboartive engagement.

    Background Chinese dietary reference intakes for calcium are largely based on foreign studies.We undertook metaregression to estimate calcium requirements for Chinese adults derived from calcium balance data in Chinese adults.Methods We searched PubMed,Cochrane CENTRAL,and SinoMed from inception to March 5,2014,by using a structured search strategy.The bibliographies of any relevant papers and journals were also screened for potentially eligible studies.We extracted a standardized data set from studies in Chinese adults that reported calcium balance data.The relationship between calcium intake and output was examined by an individual participant data (IPD) and aggregate data (AD) meta-regression.Results We identified 11 metabolic studies in Chinese adults within 18-60 years of age.One hundred and forty-one IPD (n=35) expressed as mg/d,127 IPD (n=32) expressed as mg·kg body wt-1·d-1,and 44 AD (n=132) expressed as mg/d were collected.The models predicted a neutral calcium balance (defined as calcium output (Y) equal to calcium intake (C)) at intakes of 460 mg/d (Y=0.60C+183.98) and 8.27 mg·kg body wt-1·d-1 (Y=0.60C+3.33)for IPD,or 409 mg/d (Y=0.66C+139.00) for AD.Calcium requirements at upper intakes were higher than that at lower intakes in all these models.Conclusion Calcium requirement for Chinese adults 18-60 years of age approximately ranges between 400 mg/d and 500 mg/d when consuming traditional plant-based Chinese diets.

    Collaboration is a critical competency for modern organizations as they struggle to compete in an increasingly complex, global environment. A large body of research on collaboration in the workplace focuses both on teams, investigating how groups use teamwork to perform their task work, and on the use of information systems to support team processes ("collaboration engineering"). This research essay presents collaboration from an engineering perspective ("collaborative engineering"). It uses examples from professional and student engineering teams to illustrate key differences in collaborative versus collaboration engineering and investigates how challenges in the former can inform opportunities for the latter.

    Communication is a crucial ingredient in every kind of collaborative work. But what is the least possible amount of communication required for a given task? We formalize this question by introducing a new framework for distributed computation, called {\\em oblivious protocols}. We investigate the power of this model by considering two concrete examples, the {\\em musical chairs} task $MC(n,m)$ and the well-known {\\em Renaming} problem. The $MC(n,m)$ game is played by $n$ players (processors) with $m$ chairs. Players can {\\em occupy} chairs, and the game terminates as soon as each player occupies a unique chair. Thus we say that player $P$ is {\\em in conflict} if some other player $Q$ is occupying the same chair, i.e., termination means there are no conflicts. By known results from distributed computing, if $m \\le 2n-2$, no strategy of the players can guarantee termination. However, there is a protocol with $m = 2n-1$ chairs that always terminates. Here we consider an oblivious protocol where in every time step ...

  16. {sup 2}H NMR and {sup 13}C-IRMS analyses of acetic acid from vinegar, {sup 18}O-IRMS analysis of water in vinegar: International collaborative study report

    2009-09-01

    An international collaborative study of isotopic methods applied to control the authenticity of vinegar was organized in order to support the recognition of these procedures as official methods. The determination of the {sup 2}H/{sup 1}H ratio of the methyl site of acetic acid by SNIF-NMR (site-specific natural isotopic fractionation-nuclear magnetic resonance) and the determination of the {sup 13}C/{sup 12}C ratio, by IRMS (isotope ratio mass spectrometry) provide complementary information to characterize the botanical origin of acetic acid and to detect adulterations of vinegar using synthetic acetic acid. Both methods use the same initial steps to recover pure acetic acid from vinegar. In the case of wine vinegar, the determination of the {sup 18}O/{sup 16}O ratio of water by IRMS allows to differentiate wine vinegar from vinegars made from dried grapes. The same set of vinegar samples was used to validate these three determinations. The precision parameters of the method for measuring {delta}{sup 13}C (carbon isotopic deviation) were found to be similar to the values previously obtained for similar methods applied to wine ethanol or sugars extracted from fruit juices: the average repeatability (r) was 0.45 per mille , and the average reproducibility (R) was 0.91 per mille . As expected from previous in-house study of the uncertainties, the precision parameters of the method for measuring the {sup 2}H/{sup 1}H ratio of the methyl site were found to be slightly higher than the values previously obtained for similar methods applied to wine ethanol or fermentation ethanol in fruit juices: the average repeatability was 1.34 ppm, and the average reproducibility was 1.62 ppm. This precision is still significantly smaller than the differences between various acetic acid sources ({delta}{sup 13}C and {delta}{sup 18}O) and allows a satisfactory discrimination of vinegar types. The precision parameters of the method for measuring {delta}{sup 18}O were found to be similar

    Science.gov (United States)

    Briggs, Marion C E; McElhaney, Janet E

    2015-01-01

    This chapter underscores the importance of interprofessional collaboration in the care of frail older patients. Hospital-based care is emphasized because interprofessionalism is difficult in that setting since the setting is constantly changing and since multiple healthcare professionals care for many complex, very ill patients, only some of whom are frail older people. Interprofessionalism is particularly important and challenging in teaching units in the acute care setting, where many health professionals practice and learn together and team membership changes frequently. Learning is enhanced and interprofessionalism can enhance learning by viewing the patient as a key part of the teaching team. While 'best practice' interventions have been identified for frail older adults who are hospitalized, these interventions are not easily implemented in routine hospital care. Three interdependent processes in clinical practice--representation, sense-making, and improvisation--are described, which contribute to an understanding of how practices change when implemented in a way that takes the local context into account and keeps person-centered care as the central consideration.

    Global Collaborative STEM Education, as the name suggests, simultaneously supports two sets of knowledge and skills. The first set is STEM -- science, technology, engineering and math. The other set of content knowledge and skills is that of global collaboration. Successful global partnerships require awareness of one's own culture, the biases embedded within that culture, as well as developing awareness of the collaborators' culture. Workforce skills fostered include open-mindedness, perseverance when faced with obstacles, and resourceful use of technological "bridges" to facilitate and sustain communication. In respect for the 2016 GIFT Workshop focus, Global Collaborative STEM Education projects dedicated to astronomy research will be presented. The projects represent different benchmarks within the Global Collaborative STEM Education continuum, culminating in an astronomy research experience that fully reflects how the global STEM workforce collaborates. To facilitate wider engagement in Global Collaborative STEM Education, project summaries, classroom resources and contact information for established international collaborative astronomy research projects will be disseminated.

  4. Perceptions of collaboration: A comparison of educators and scientists for COSEE Great Lakes

    Science.gov (United States)

    Kim, Chankook

    The Great Lakes region of North America, holding 20% of the world's fresh water and home to ¼ of the U.S. population, can provide its 13 million K-12 learners with a relevant context for science learning, unique opportunities for exploring local environmental issues, and connections to global issues. By linking Great Lakes research scientists with educators, students, and the public, the COSEE (Centers for Ocean Sciences Education Excellence) Great Lakes pursues its goal of enhancing science and environmental literacy of both adults and students. This doctoral research had a three-fold purpose in the COSEE Great Lakes context. First, this study aimed to characterize the population of Great Lakes scientists and K-12 teachers in the Great Lakes region targeted as potential audiences for activities of COSEE Great Lakes. Second, this study aimed to identify factors that may affect educational collaboration between teachers and scientists. Third, this study was conducted as a part of an ongoing process of evaluating overall COSEE program outcomes related to increasing educational collaborations. This dissertation consists of three research reports on professional development and interprofessional collaboration of K-12 teachers and scientists. The first report in Chapter 2 investigates primary and secondary teachers' views of collaboration with scientists and incorporates the findings of teacher surveys into discussions about professional development programs for educators. From 180 schools randomly selected in the eight Great Lakes States, 194 primary and secondary educators responded to a mailed survey. Through the survey responses, the educators reported that while they have positive attitudes toward their collaboration with scientists, their professional preparation has not equipped them with enough understanding of the process of science and the professions of scientists. Regression analysis shows that five predictor variables account for a majority of the variance

    Moyle, Steve

    Collaborative Data Mining is a setting where the Data Mining effort is distributed to multiple collaborating agents - human or software. The objective of the collaborative Data Mining effort is to produce solutions to the tackled Data Mining problem which are considered better by some metric, with respect to those solutions that would have been achieved by individual, non-collaborating agents. The solutions require evaluation, comparison, and approaches for combination. Collaboration requires communication, and implies some form of community. The human form of collaboration is a social task. Organizing communities in an effective manner is non-trivial and often requires well defined roles and processes. Data Mining, too, benefits from a standard process. This chapter explores the standard Data Mining process CRISP-DM utilized in a collaborative setting.

  6. Persistent Homology of Collaboration Networks

    Directory of Open Access Journals (Sweden)

    C. J. Carstens

    2013-01-01

    Full Text Available Over the past few decades, network science has introduced several statistical measures to determine the topological structure of large networks. Initially, the focus was on binary networks, where edges are either present or not. Thus, many of the earlier measures can only be applied to binary networks and not to weighted networks. More recently, it has been shown that weighted networks have a rich structure, and several generalized measures have been introduced. We use persistent homology, a recent technique from computational topology, to analyse four weighted collaboration networks. We include the first and second Betti numbers for the first time for this type of analysis. We show that persistent homology corresponds to tangible features of the networks. Furthermore, we use it to distinguish the collaboration networks from similar random networks.

Research, development, social programs, and ongoing ventures of all sorts benefit from interactions between teams, groups, and organizations, across intellectual disciplines and across facets and features of the inquiry, product, entity, or activity under consideration. We present a survey of the state of collaboration and collaborative enterprise, in the context of papers and presentations at the International Symposium on Collaborative Enterprises 2011 (CENT 2011, and the extended papers appearing in this special issue.

    2006-01-01

    Collaborative Care refers to a partnership between healthcare professionals and patients who feel confident to manage their health conditions. Using an Internet-based assessment of health needs and healthcare quality, we surveyed 24,609 adult Americans aged 19 to 69 who had common chronic diseases or significant dysfunction. In these patients, we examined the association of Collaborative Care with specific measures for treatment effect, disease control, prevention, and economic impacts. These measures were adjusted for respondents' demographic characteristics, burden of illness, health behaviors, and overall quality of healthcare. Only 21% of respondents participated in good Collaborative Care, 36% attained fair Collaborative Care, and 43% experienced poor Collaborative Care. Regardless of overall care quality or the respondents' personal characteristics, burden of illness, or health behaviors, good Collaborative Care was associated with better control of blood pressure, blood glucose level, serum cholesterol level, and treatment effectiveness for pain and emotional problems. Some preventive actions were better, and some adverse economic impacts of illness were mitigated. PMID:16788352

  18. Emergence of multiplex communities in collaboration networks

    CERN Document Server

    Battiston, Federico; Nicosia, Vincenzo; Bianconi, Ginestra; Latora, Vito

    2015-01-01

    Community structures in collaboration networks reflect the natural tendency of individuals to organize their work in groups in order to better achieve common goals. In most of the cases, individuals exploit their connections to introduce themselves to new areas of interests, giving rise to multifaceted collaborations which span different fields. In this paper, we analyse collaborations in science and among movie actors as multiplex networks, where the layers represent respectively research topics and movie genres, and we show that communities indeed coexist and overlap at the different layers of such systems. We then propose a model to grow multiplex networks based on two mechanisms of intra and inter-layer triadic closure which mimic the real processes in which collaborations evolve. We show that our model is able to explain the multiplex community structure observed empirically, and we infer the strength of the two underlying social mechanisms from real-world systems. Being also able to correctly reproduce ...

    Collaboration among health-care providers has emerged as a key factor in improving client care. The authors describe the Geriatric Emergency Management-Falls Intervention Team (GEM-FIT) project, a nurse-led research initiative to improve fall prevention in older adults through interdisciplinary collaboration. Public health nurses and occupational therapists assessed participants before and after fall-prevention interventions and fou modest improvements in participant outcomes and reductions in modifiable risk factors. The project resulted in successful collaboration, interdisciplinary teamwork and improved service delivery to participants. Among the challenges were delayed timelines, complex issues outside the project protocol and communication difficulties. The authors, who served on the project team, make recommendations for health-care professionals interested in initiating similar projects. PMID:22128708

  18. On Coordinating Collaborative Objects

    Directory of Open Access Journals (Sweden)

    Abdessamad Imine

    2010-07-01

    Full Text Available A collaborative object represents a data type (such as a text document designed to be shared by a group of dispersed users. The Operational Transformation (OT is a coordination approach used for supporting optimistic replication for these objects. It allows the users to concurrently update the shared data and exchange their updates in any order since the convergence of all replicas, i.e. the fact that all users view the same data, is ensured in all cases. However, designing algorithms for achieving convergence with the OT approach is a critical and challenging issue. In this paper, we propose a formal compositional method for specifying complex collaborative objects. The most important feature of our method is that designing an OT algorithm for the composed collaborative object can be done by reusing the OT algorithms of component collaborative objects. By using our method, we can start from correct small collaborative objects which are relatively easy to handle and incrementally combine them to build more complex collaborative objects.

  19. Collaborations in fusion research

    International Nuclear Information System (INIS)

    This paper reviews current experimental collaborative efforts in the fusion community and extrapolates to operational scenarios for the Tokamak Physics Experiment (TPX) and the International Thermonuclear Experimental Reactor (ITER). Current requirements, available technologies and tools, and problems, issues and concerns are discussed. This paper specifically focuses on the issues that apply to experimental operational collaborations. Special requirements for other types of collaborations, such as theoretical or design and construction efforts, will not be addressed. Our current collaborative efforts have been highly successful, even though the tools in use will be viewed as primitive by tomorrow's standards. An overview of the tools and technologies in today's collaborations can be found in the first section of this paper. The next generation of fusion devices will not be primarily institutionally based, but will be national (TPX) and international (ITER) in funding, management, operation and in ownership of scientific results. The TPX will present the initial challenge of real-time remotely distributed experimental data analysis for a steady state device. The ITER will present new challenges with the possibility of several remote control rooms all participating in the real-time operation of the experimental device. A view to the future of remote collaborations is provided in the second section of this paper

  20. Creating collaborative learning environments for transforming primary care practices now.

    Science.gov (United States)

    Miller, William L; Cohen-Katz, Joanne

    2010-12-01

    The renewal of primary care waits just ahead. The patient-centered medical home (PCMH) movement and a refreshing breeze of collaboration signal its arrival with demonstration projects and pilots appearing across the country. An early message from this work suggests that the development of collaborative, cross-disciplinary teams may be essential for the success of the PCMH. Our focus in this article is on training existing health care professionals toward being thriving members of this transformed clinical care team in a relationship-centered PCMH. Our description of the optimal conditions for collaborative training begins with delineating three types of teams and how they relate to levels of collaboration. We then describe how to create a supportive, safe learning environment for this type of training, using a different model of professional socialization, and tools for building culture. Critical skills related to practice development and the cross-disciplinary collaborative processes are also included. Despite significant obstacles in readying current clinicians to be members of thriving collaborative teams, a few next steps toward implementing collaborative training programs for existing professionals are possible using competency-based and adult learning approaches. Grasping the long awaited arrival of collaborative primary health care will also require delivery system and payment reform. Until that happens, there is an abundance of work to be done envisioning new collaborative training programs and initiating a nation-wide effort to motivate and reeducate our colleagues.

    2005-05-01

    Unmanned ground and air systems operating in collaboration have the potential to provide future Joint Forces a significant capability for operations in complex terrain. Ground and air collaborative engagements potentially offer force conservation, perform timely acquisition and dissemination of essential combat information, and can eliminate high value and time critical targets. These engagements can also add considerably to force survivability by reducing soldier and equipment exposure during critical operations. The Office of the Secretary of Defense, Joint Robotics Program (JRP) sponsored Collaborative Engagement Experiment (CEE) is a consolidation of separate Air Force, Army and Navy collaborative efforts to provide a Joint capability. The Air Force Research Laboratory (AFRL), Material and Manufacturing Directorate, Aerospace Expeditionary Force Division, Force Protection Branch (AFRLMLQF), The Army Aviation and Missile Research, Development and Engineering Center (AMRDEC) Joint Technology Center (JTC)/Systems Integration Laboratory (SIL), and the Space and Naval Warfare Systems Center-San Diego (SSC San Diego) are conducting technical research and proof of principle for an envisioned operational concept for extended range, three dimensional, collaborative operations between unmanned systems, with enhanced situational awareness for lethal operations in complex terrain. This program will assess information requirements and conduct experiments to identify and resolve technical risks for collaborative engagements using Unmanned Ground Vehicles (UGVs) and Unmanned Aerial Vehicles (UAVs). It will research, develop and physically integrate multiple unmanned systems and conduct live collaborative experiments. Modeling and Simulation systems will be upgraded to reflect engineering fidelity levels to greater understand technical challenges to operate as a team. This paper will provide an update of a multi-year program and will concentrate primarily on the JTC

    Open Access Publication Policy ATLAS had recently issued a short statement in support of open access publishing. The mood of the discussions in the December CMS Collaboration Board had appeared to be in favour and so it was being proposed that CMS issue the same statement as that made by ATLAS (the statement is attached to the agenda of this meeting). The Collaboration Board agreed. Election of the Chair of the Collaboration Board Following the agreement to shorten the terms of both the Spokesperson and the Collaboration Board Chair, and to introduce a longer overlap period between the election and the start of the term, the election for the next Collaboration Board Chair was due in December 2007. If the old standard schedule specified in the Constitution were adapted to this date, then the Board should be informed at the present meeting that the election was being prepared. However, it was felt that the experience of the previous year's election of the Spokesperson had shown that it would be desirable to...

  5. Distance collaborations with industry

    The college industry relationship has been identified as a key policy issue in Engineering Education. Collaborations between academic institutions and the industrial sector have a long history and a bright future. For Engineering and Engineering Technology programs in particular, industry has played a crucial role in many areas including advisement, financial support, and practical training of both faculty and students. Among the most important and intimate interactions are collaborative projects and formal cooperative education arrangements. Most recently, such collaborations have taken on a new dimension, as advances in technology have made possible meaningful technical collaboration at a distance. There are several obvious technology areas that have contributed significantly to this trend. Foremost is the ubiquitous presence of the Internet. Perhaps almost as important are advances in computer based imaging. Because visual images offer a compelling user experience, it affords greater knowledge transfer efficiency than other modes of delivery. Furthermore, the quality of the image appears to have a strongly correlated effect on insight. A good visualization facility offers both a means for communication and a shared information space for the subjects, which are among the essential features of both peer collaboration and distance learning.

  6. Trust in interprofessional collaboration

    Gregory, Paul A. M.; Austin, Zubin

    2016-01-01

    Background: Trust is integral to effective interprofessional collaboration. There has been scant literature characterizing how trust between practitioners is formed, maintained or lost. The objective of this study was to characterize the cognitive model of trust that exists between pharmacists and family physicians working in collaborative primary care settings. Methods: Pharmacists and family physicians who work collaboratively in primary care were participants in this study. Family health teams were excluded from this study because of the distinct nature of these settings. Through a snowball convenience sampling method, a total of 11 pharmacists and 8 family physicians were recruited. A semistructured interview guide was used to guide discussion around trust, relationships and collaboration. Constant-comparative coding was used to identify themes emerging from these data. Results: Pharmacists and family physicians demonstrate different cognitive models of trust in primary care collaboration. For pharmacists, trust appears to be conferred on physicians based on title, degree, status and positional authority. For family physicians, trust appears to be earned based on competency and performance. These differences may lead to interprofessional tension when expectations of reciprocal trust are not met. Conclusions: Further work in characterizing how trust is developed in interprofessional relationships is needed to support effective team formation and functioning.

  7. Role of Scientific Societies in International Collaboration

    2007-12-01

    Geophysical research increasingly requires global multidisciplinary approaches. Understanding how deeply interrelated are Earth components and processes, population growth, increased needs of mineral and energy resources, global impact of human activities, and view of our planet as an interconnected system emphasizes the need of international cooperation. International research collaboration has an immense potential and is needed for further development of Earth science research and education. The Union Session is planned to provide a forum for analysis and discussion of the status of research and education of geosciences in developing countries, international collaboration programs and new initiatives for promoting and strengthening scientific cooperation. A theme of particular relevance in the analyses and discussions is the role of scientific societies in international collaboration. Societies organize meetings, publish journals and books and promote cooperation through academic exchange activities. They may further assist communities in developing countries in providing and facilitating access to scientific literature, attendance to international meetings, short and long-term stays and student and young researcher mobility. What else can be done? This is a complex subject and scientific societies may not be seen independently from the many factors involved in research and education. Developing countries present additional challenges resulting from limited economic resources and social and political problems, while urgently requiring improved educational and research programs. Needed are in-depth analyses of infrastructure and human resources, and identification of major problems and needs. What are the major limitations and needs in research and postgraduate education in developing countries? What and how should international collaboration do? What are the roles of individuals, academic institutions, funding agencies, scientific societies? Here we attempt to

    We use the notion of emergence to consider the sorts of knowledge that can be produced in a collaborative research project. The notion invites us to see collaborative work as a developmental dynamic system in which various changes constantly occur. Among these we examine two sorts of knowledge that can be produced: scientific knowledge, and collaborative knowledge. We argue that collaborative knowledge can enable researchers to reflectively monitor their collaborative project, so as to encour...

    Since 2009, the development of Indico has focused on usability, performance and new features, especially the ones related to meeting collaboration. Usability studies have resulted in the biggest change Indico has experienced up to now, a new web layout that makes user experience better. Performance improvements were also a key goal since 2010; the main features of Indico have been optimized remarkably. Along with usability and performance, new features have been added to Indico such as webchat integration, video services bookings, webcast and recording requests, designed to really reinforce Indico position as the main hub for all CERN collaboration services, and many others which aim is to complete the conference lifecycle management. Indico development is also moving towards a broader collaboration where other institutes, hosting their own Indico instance, can contribute to the project in order make it a better and more complete tool.

    2014-04-01

    Addressing global sustainability challenges--including climate change, resource depletion, and ecosystem loss--is beyond the individual capabilities of even the largest companies. To tackle these threats, and unleash new value, companies and other stakeholders must collaborate in new ways that treat fragile and complex ecosystems as a whole. In this article, the authors draw on cases including the Latin American Water Funds Partnership, the Sustainable Apparel Coalition (led by Nike, Patagonia, and Walmart), and Action to Accelerate Recycling (a partnership between Alcoa, consumer packaged goods companies, and local governments, among others) to describe four new collaboration models that create shared value and address environmental protection across the value stream. Optimal collaborations focus on improving either business processes or outcomes. They start with a small group of key organizations, bring in project management expertise, link self-interest to shared interest, encourage productive competition, create quick wins, and, above all, build and maintain trust.

    2012-01-01

    This is the third in a series of columns exploring health information technology (HIT) in the neonatal intensive care unit (NICU). The first column provided background information on the implementation of information technology throughout the health care delivery system, as well as the requisite informatics competencies needed for nurses to fully engage in the digital era of health care. The second column focused on information and resources to master basic computer competencies described by the TIGER initiative (Technology Informatics Guiding Education Reform) as learning about computers, computer networks, and the transfer of data.1 This column will provide additional information related to basic computer competencies, focusing on communication and collaboration technologies. Computers and the Internet have transformed the way we communicate and collaborate. Electronic communication is the ability to exchange information through the use of computer equipment and software.2 Broadly defined, any technology that facilitates linking one or more individuals together is a collaborative tool. Collaboration using technology encompasses an extensive range of applications that enable groups of individuals to work together including e-mail, instant messaging (IM ), and several web applications collectively referred to as Web 2.0 technologies. The term Web 2.0 refers to web applications where users interact and collaborate with each other in a collective exchange of ideas generating content in a virtual community. Examples of Web 2.0 technologies include social networking sites, blogs, wikis, video sharing sites, and mashups. Many organizations are developing collaborative strategies and tools for employees to connect and interact using web-based social media technologies.3. PMID:22397797

  2. Collaborative Movie Annotation

    Science.gov (United States)

    Zad, Damon Daylamani; Agius, Harry

    In this paper, we focus on metadata for self-created movies like those found on YouTube and Google Video, the duration of which are increasing in line with falling upload restrictions. While simple tags may have been sufficient for most purposes for traditionally very short video footage that contains a relatively small amount of semantic content, this is not the case for movies of longer duration which embody more intricate semantics. Creating metadata is a time-consuming process that takes a great deal of individual effort; however, this effort can be greatly reduced by harnessing the power of Web 2.0 communities to create, update and maintain it. Consequently, we consider the annotation of movies within Web 2.0 environments, such that users create and share that metadata collaboratively and propose an architecture for collaborative movie annotation. This architecture arises from the results of an empirical experiment where metadata creation tools, YouTube and an MPEG-7 modelling tool, were used by users to create movie metadata. The next section discusses related work in the areas of collaborative retrieval and tagging. Then, we describe the experiments that were undertaken on a sample of 50 users. Next, the results are presented which provide some insight into how users interact with existing tools and systems for annotating movies. Based on these results, the paper then develops an architecture for collaborative movie annotation.

Collaboration initiatives remain a challenge for many researchers for a myriad of reasons which are further intensified by the many technology options that are available both freely and at varying prices. Although multiple theories were considered, the focus on electronic communication supported by the interest in how innovation is diffused and the richness of media motivated the focus on diffusion of innovations (DOI and media richness theory (MRT.Objectives: The objective was to develop a multi-dimensional matrix of e-collaboration factors for research institutions. This study investigated collaboration by ARIs while focusing on the supporting and enabling technologies.Method: The grounded theory method (GTM was adopted. E-collaboration literature was reviewed followed by data collection using observations, interviews and a blog. DOI and MRT were considered as theories that assist in the implementation of collaboration. A blog was developed as an e-collaboration platform to examine the emergent ideas and to collect data. Data was analysed through the coding method which led to the development of the multi-dimensional e-collaboration factors matrix.Results: The findings reveal that e-collaboration has multiple factors that must be considered. Collaboration by participants was improved through knowledge development and innovation.Conclusion: The multi-dimensional matrix of e-collaboration factors presented collaborators with a checklist that will enhance and improve their work.

    Since 2007/2008 project-based learning models have been used to deliver two fundamental courses on Geotechnics in University of Aveiro, Portugal. These models have evolved and have encompassed either cooperative or collaborative teamwork. Using data collected in five editions of each course (Soil Mechanics I and Soil Mechanics II), the different characteristics of the models using cooperative or collaborative teamwork are pointed out and analysed, namely in terms of the students' perceptions. The data collected include informal feedback from students, monitoring of their marks and academic performance, and answers to two sets of questionnaires: developed for these courses, and institutional. The data indicate students have good opinion of the project-based learning model, though collaborative teamwork is the best rated. The overall efficacy of the models was analysed (sum of their effectiveness, efficiency and attractiveness). The collaborative model was found more adequate.

    The Pro-Am Collaborative Astronomy (PACA) project is the next stage of evolution of the paradigm developed for the observational campaign of C/2012 S1 or C/ISON. Four different phases of collaboration are identified, and illustrate the integration of scientific investigations with amateur astronomer community via observations, and models; and the rapid dissemination of the results via a multitude of social media for rapid global access. The success of the paradigm shift in scientific research is now implemented in other comet observing campaigns. Both communities (scientific and amateur astronomers) benefit from these collective, collaborative partnerships; while outreach is the instantaneous deliverable that provides both a framework for future data analyses and the dissemination of the results. While PACA identifies a collaborative approach to pro-am collaborations, given the volume of data generated for each campaign, new ways of rapid data analysis, mining access and storage are needed.

    We often remember in groups, yet research on collaborative recall finds “collaborative inhibition”: Recalling with others has costs compared to recalling alone. In related paradigms, remembering with others introduces errors into recall. We compared costs and benefits of two collaboration...... procedures—turn taking and consensus. First, 135 individuals learned a word list and recalled it alone (Recall 1). Then, 45 participants in three-member groups took turns to recall, 45 participants in three-member groups reached a consensus, and 45 participants recalled alone but were analysed as three......-member nominal groups (Recall 2). Finally, all participants recalled alone (Recall 3). Both turn-taking and consensus groups demonstrated the usual pattern of costs during collaboration and benefits after collaboration in terms of recall completeness. However, consensus groups, and not turn-taking groups...

    International Nuclear Information System (INIS)

    Conditions for collaboration in research and development (R and D) were developed based on a decision-tree analysis. A key requirement for effective R and D collaboration was stated to be the company's ability to internalize a significant portion of the benefits. This was seen as the principal factor that determined good collaborators and good industries for collaboration. It was noted that collaboration benefits can also be improved through R and D exchanges in collaborative associations. Simple decision-tree analysis tended to understate the advantages of collaboration. Portfolio risk reduction and inter-project synergies were significant additional advantages. Collaborative R and D was said to be the preferred route for the development of a broad base of petroleum-related technologies. 5 tabs., 2 figs

    Using bibliometric methods, we investigate China's international scientific collaboration from 3 levels of collaborating countries, institutions and individuals. We design a database in SQL Server, and make analysis of Chinese SCI papers based on the corresponding author field. We find that China's international scientific collaboration is focused on a handful of countries. Nearly 95% international co-authored papers are collaborated with only 20 countries, among which the USA account for more than 40% of all. Results also show that Chinese lineage in the international co-authorship is obvious, which means Chinese immigrant scientists are playing an important role in China's international scientific collaboration, especially in English-speaking countries.

    Full Text Available There has been considerable interest among Public Administration scholars in collaborative public management and governance. However, there is a need for conceptual analysis of the two terms which share common aspects and differ essentially in scope and substance. We found that collaborative public management has a more local approach and focuses on the substance of collaboration practiced to solve societal problems and reach community goals at the organizational level. On the other hand, widely researched in management, political science, and public administration disciplines, collaborative governance has a global scope and focuses on both substance and process of collaboration in effectively solving societal problems with improved structures of nonhierarchical and decentralized institutions and mechanisms of citizen participation both through partnership projects and e-governance tools. The paper contributes to the better understanding of collaborative public management and collaborative governance with implications for both future research and practice.

    Full Text Available Introduction: HIV care and treatment programmes worldwide are transforming as they push to deliver universal access to essential prevention, care and treatment services to persons living with HIV and their communities. The characteristics and capacity of these HIV programmes affect patient outcomes and quality of care. Despite the importance of ensuring optimal outcomes, few studies have addressed the capacity of HIV programmes to deliver comprehensive care. We sought to describe such capacity in HIV programmes in seven regions worldwide. Methods: Staff from 128 sites in 41 countries participating in the International epidemiologic Databases to Evaluate AIDS completed a site survey from 2009 to 2010, including sites in the Asia-Pacific region (n=20, Latin America and the Caribbean (n=7, North America (n=7, Central Africa (n=12, East Africa (n=51, Southern Africa (n=16 and West Africa (n=15. We computed a measure of the comprehensiveness of care based on seven World Health Organization-recommended essential HIV services. Results: Most sites reported serving urban (61%; region range (rr: 33–100% and both adult and paediatric populations (77%; rr: 29–96%. Only 45% of HIV clinics that reported treating children had paediatricians on staff. As for the seven essential services, survey respondents reported that CD4+ cell count testing was available to all but one site, while tuberculosis (TB screening and community outreach services were available in 80 and 72%, respectively. The remaining four essential services – nutritional support (82%, combination antiretroviral therapy adherence support (88%, prevention of mother-to-child transmission (PMTCT (94% and other prevention and clinical management services (97% – were uniformly available. Approximately half (46% of sites reported offering all seven services.

    Large-scale facilities such as power plants, process factories, ships and communication infrastructures are often engineered and delivered through geographically distributed operations. The competencies required are usually distributed across several contributing organisations. In these complicated projects, it is of key importance that all partners work coherently towards a common goal. VTT and a number of industrial organisations in the marine sector have participated in a national collaborative research programme addressing these needs. The main output of this programme was development of the Innovation and Engineering Maturity Model for Marine-Industry Networks. The recently completed European Union Framework Programme 7 project COIN developed innovative solutions and software services for enterprise collaboration and enterprise interoperability. One area of focus in that work was services for collaborative project management. This article first addresses a number of central underlying research themes and previous research results that have influenced the development work mentioned above. This article presents two approaches for the development of services that support distributed engineering work. Experience from use of the services is analysed, and potential for development is identified. This article concludes with a proposal for consolidation of the two above-mentioned methodologies. This article outlines the characteristics and requirements of future services supporting collaborative alignment of engineering networks.

  6. WIKIPEDIA AND THE POLITICS OF MASS COLLABORATION

    2010-01-01

    Full Text Available Working together to produce socio-technological objects, based on emergent platforms of economic production, is of great importance in the task of political transformation and the creation of new subjectivities. Increasingly, “collaboration” has become a veritable buzzword used to describe the human associations that create such new media objects. In the language of “Web 2.0”, “participatory culture”, “user-generated content”, “peer production” and the “produser”, first and foremost we are all collaborators. In this paper I investigate recent literature that stresses the collaborative nature of Web 2.0, and in particular, works that address the nascent processes of peer production. I contend that this material positions such projects as what Chantal Mouffe has described as the “post-political”; a fictitious space far divorced from the clamour of the everyday. I analyse one Wikipedia entry to demonstrate the distance between this post-political discourse of collaboration and the realities it describes, and finish by arguing for a more politicised notion of collaboration.

    Community structures in collaboration networks reflect the natural tendency of individuals to organize their work in groups in order to better achieve common goals. In most of the cases, individuals exploit their connections to introduce themselves to new areas of interests, giving rise to multifaceted collaborations which span different fields. In this paper, we analyse collaborations in science and among movie actors as multiplex networks, where the layers represent respectively research topics and movie genres, and we show that communities indeed coexist and overlap at the different layers of such systems. We then propose a model to grow multiplex networks based on two mechanisms of intra and inter-layer triadic closure which mimic the real processes by which collaborations evolve. We show that our model is able to explain the multiplex community structure observed empirically, and we infer the strength of the two underlying social mechanisms from real-world systems. Being also able to correctly reproduce the values of intra-layer and inter-layer assortativity correlations, the model contributes to a better understanding of the principles driving the evolution of social networks.

    The U. S. Department of Energy (DOE), National Association of State Energy Officials (NASEO), and Association of State Energy Research and Technology Transfer Institutions (ASERTTI) signed an intergovernmental agreement on November 14, 2002, that allowed states and territories and the Federal Government to better collaborate on energy research, development, demonstration and deployment (RDD&D) projects. The agreement established the State Technologies Advancement Collaborative (STAC) which allowed the states and DOE to move RDD&D forward using an innovative competitive project selection and funding process. A cooperative agreement between DOE and NASEO served as the contracting instrument for this innovative federal-state partnership obligating funds from DOE's Office of Energy Efficiency and Renewable Energy and Office of Fossil Energy to plan, fund, and implement RDD&D projects that were consistent with the common priorities of the states and DOE. DOE's Golden Field Office provided Federal oversight and guidance for the STAC cooperative agreement. The STAC program was built on the foundation of prior Federal-State efforts to collaborate on and engage in joint planning for RDD&D. Although STAC builds on existing, successful programs, it is important to note that it was not intended to replace other successful joint DOE/State initiatives such as the State Energy Program or EERE Special Projects. Overall the STAC process was used to fund, through three competitive solicitations, 35 successful multi-state research, development, deployment, and demonstration projects with an overall average non-federal cost share of 43%. Twenty-two states were awarded at least one prime contract, and organizations in all 50 states and some territories were involved as subcontractors in at least one STAC project. Projects were funded in seven program areas: (1) Building Technologies, (2) Industrial Technologies, (3) Transportation Technologies, (4) Distributed Energy

    Background Young adults have the highest smoking rate of any age group in the U.S., and new strategies to decrease young adult smoking are needed. The objective of the current study was to identify psychographic and demographic factors associated with current smoking and quitting behaviors among young adults. Methods Attitudes, social groups, and self-descriptors, including supporting action against the tobacco industry, advertising receptivity, depression, alcohol use, and other factors associated with smoking were tested for associations with smoking behaviors in a 2005 cross-sectional survey of 1528 young adults (aged 18–25 years) from a web-enabled panel. Analyses were conducted in 2007. Results Being older was associated with current smoking, whereas having some higher education and being African American or Hispanic were negatively associated with smoking. Supporting action against the tobacco industry was negatively associated with smoking (AOR=0.34 [95% CI=0.22, 0.52]). Perceived usefulness of smoking, exposure to smokers, increased perceived smoking prevalence, receptivity to tobacco advertising, binge drinking, and exposure to tobacco advertising in bars and clubs were associated with smoking. Supporting action against the tobacco industry was associated with intentions to quit smoking (AOR= 4.43 [95% CI=2.18, 8.60]). Conclusions Young adults are vulnerable to tobacco-industry advertising. Media campaigns that denormalize the tobacco industry and appeal to young adults appear to be a powerful intervention to decrease young adult smoking. PMID:19269128

    Full Text Available “Web 2.0” is the mantra enthusiastically repeated in the past few years on anything concerning the production of culture, dialogue and online communication. Even science is changing, along with the processes involving the communication, collaboration and cooperation created through the web, yet rooted in some of its historical features of openness. For this issue, JCOM has asked some experts on the most recent changes in science to analyse the potential and the contradictions lying in online collaborative science. The new open science feeds on the opportunity to freely contribute to knowledge production, sharing not only data, but also software and hardware. But it is open also to the outside, where citizens use Web 2.0 instruments to discuss about science in a horizontal way.

    Scientific collaborations are established for a wide variety of tasks for which several communication modes are necessary, including messaging, file-sharing, and collaborative editing. In this position paper, we describe our work on the Pervasive Collaborative Computing Environment (PCCE) which aims to facilitate scientific collaboration within widely distributed environments. The PCCE provides a persistent space in which collaborators can locate each other, exchange messages synchronously and asynchronously and archive conversations. Our current interest is in exploring research and development of shared editing systems with the goal of integrating this technology into the PCCE. We hope to inspire discussion of technology solutions for an integrated approach to synchronous and asynchronous communication and collaborative editing.

    ENGLISH ABSTRACT: The production of scientific publications in engineering in South Africa has expanded over the last three decades. Because engineering is an important science, this expansion has implications for the growth and development of the economy. Drawing on a sample range of years of the publications stored in the ISI Web of Knowledge, the engineering publications of South Africans for a 30-year period from 1975-2005 are analysed. This analysis shows that the production of scientific publications in engineering by South African researchers has increased during the analysed period; that the number of researchers per publication has grown; that the number of countries collaborating with South Africa has increased; and that the number of sole-authored papers has decreased. Domestic collaboration (between researchers within South Africa has decreased, while international collaboration has grown considerably. The key objective of the paper is to find out whether the production of publications is related to the level of collaboration, and to see how collaboration can be regressed from other known variables. It is clear from the study that collaboration is a decisive factor in the production of scientific publications in engineering in South Africa.

    The objective of the Advanced Collaborative Emissions Study (ACES) was to determine before widespread commercial deployment whether or not the new, energy-efficient, heavy duty diesel engines (2007 and 2010 EPA Emissions Standards Compliant) may generate anticipated toxic emissions that could adversely affect the environment and human health. ACES was planned to take place in three phases. In Phase 1, extensive emissions characterization of four production-intent prototype engine and control systems designed to meet 2007 standards for nitrogen oxides (NOx) and particulate matter (PM) was conducted at an existing emissions characterization facility: Southwest Research Institute (SwRI). One of the tested engines was selected (at random, after careful comparison of results) for health testing in Phase 3. In Phase 2, extensive emission characterization of three production-intent prototype engine and control systems meeting the 2010 standards (including more advanced NOx controls to meet the more stringent 2010 NOx standards) was conducted at the same test facility. In Phase 3, one engine/aftertreatment system selected from Phase 1 was further characterized during health effects studies (at an existing inhalation toxicology laboratory: Lovelace Respiratory Research Institute, [LRRI]) to form the basis of the ACES safety assessment. The Department of Energy (DOE) award provided funding for emissions characterization in Phases 1 and 2 as well as exposure characterization in Phase 3. The main health analyses in Phase 3 were funded separately and are not reported here.

It’s a year that holds particular significance for CERN, as on 29 September it will be 60 years since the Organization was founded.   As CERN turns 60, it is still going strong, maintaining its underlying attraction of international collaboration for basic science. Since its foundation in 1954, it has grown steadily and this year begins well as we welcome a new Member State, Israel. CERN and Israel already have a long history of mutual collaboration and now we can look forward to increasingly fruitful scientific cooperation. Israel’s accession brings the total number of Member States to 21, and other countries are in the stages leading up to becoming Members or Associates, while still others are expressing interest. CERN is becoming a global success, while retaining its original, European flavour. This year’s events for the 60th anniversary ...

    Full Text Available ABSTRACT The Global University System (GUS [Utsumi, et al, 2003] is a worldwide initiative to create advanced telecommunications infrastructure for access to educational resources across national and cultural boundaries for global peace. GUS aims to create a worldwide consortium of universities to provide the underdeveloped world with access to 21st Century education via broadband Internet technologies. The aim is to achieve “education and healthcare for all,” anywhere, anytime and at any pace. The GUS works in the major regions of the globe with partnerships of higher education and healthcare institutions. Learners in these regions will be able to take their courses from member institutions around the world to receive a GUS degree. These learners and their professors from partner institutions will also form a global forum for exchange of ideas and information and for conducting collaborative research and development with emerging global GRID computer network technology. Globally Collaborative Environmental Peace Gaming (GCEPG project [Utsumi, 2003] with a globally distributed computer simulation system, focusing on the issue of environment and sustainable development in developing countries, is to train would-be decision-makers in crisis management, conflict resolution, and negotiation techniques basing on “facts and figures.” The GUS will supply game players from around the world.

  5. Collaboration in Social Networks

    CERN Document Server

    Dall'Asta, Luca; Pin, Paolo

    2011-01-01

    The very notion of social network implies that linked individuals interact repeatedly with each other. This allows them not only to learn successful strategies and adapt to them, but also to condition their own behavior on the behavior of others, in a strategic forward looking manner. Game theory of repeated games shows that these circumstances are conducive to the emergence of collaboration in simple games of two players. We investigate the extension of this concept to the case where players are engaged in a local contribution game and show that rationality and credibility of threats identify a class of Nash equilibria -- that we call "collaborative equilibria" -- that have a precise interpretation in terms of sub-graphs of the social network. For large network games, the number of such equilibria is exponentially large in the number of players. When incentives to defect are small, equilibria are supported by local structures whereas when incentives exceed a threshold they acquire a non-local nature, which r...

    2012-01-01

    Full Text Available Background: The quality of service and success of patient care and research in most fields of medicine depend on effective collaboration between different specialties. Paediatric surgery is a relatively young specialty in Nigeria and such collaborations are desirable. This survey assesses the nature and extent of collaboration between paediatric surgery and other specialties in Nigeria. Materials and Methods: This is a questionnaire survey carried out in November 2008 among paediatric surgeons and their trainees practising in Nigeria. Questionnaires were distributed and retrieved either by hand or e-mailing. The responses were then collated and analysed using the SPSS 17.0. Results: Forty-seven respondents were included in the survey. Forty-five (95.7% respondents thought that there was inadequate collaboration and that there was a need for an increased collaboration between paediatric surgery and other specialties. Anaesthesia, paediatrics and radiology are among the specialties where collaborations were most required but not adequately received. Collaboration had been required from these specialties in areas of patient care, training and research. Reasons for inadequate collaboration included the paucity of avenues for inter-specialty communication and exchange of ideas 33 (70.3%, lack of awareness of the need for collaboration 32 (68.1%, tendency to apportion blames for bad outcome 13 (27.7%, and mutual suspicion 8 (17%. Conclusion: There is presently inadequate collaboration between paediatric surgery and other specialties in Nigeria. There is a need for more inter-specialty support, communication, and exchange of ideas in order to achieve desirable outcomes.

    This paper explores the geographical distance of innovation collaborations in high tech small firms. We test if absorptive capacity is a key determinant. Drawing on survey data from a sample of 316 Dutch high-tech small firms, engaging in 1.245 collaborations, we find most partners to be ‘local’. However, controlling for a variety of potential influences, higher R&D expenditure is positively related to collaboration with more distant organisations.

    2002-05-22

    To enable collaboration on the daily tasks involved in scientific research, collaborative frameworks should provide lightweight and ubiquitous components that support a wide variety of interaction modes. We envision a collaborative environment as one that provides a persistent space within which participants can locate each other, exchange synchronous and asynchronous messages, share documents and applications, share workflow, and hold videoconferences. We are developing the Pervasive Collaborative Computing Environment (PCCE) as such an environment. The PCCE will provide integrated tools to support shared computing and task control and monitoring. This paper describes the PCCE and the rationale for its design.

    Full Text Available UK public policy makers have a growing interest in collaborative research, where academics work with public, private or third sector partners on a joint project which supports the partner’s aims. This paper reports on the findings of five case studies, looking at how information is sourced, managed, used and shared within collaborative research projects. It finds that researchers within collaborative projects have similar information management issues as are known to exist within academia more broadly, but that the specific conditions which govern research collaborations mean that interventions to improve or support information management must be carefully tailored.

  2. Additive Manufacturing Cloud via Peer-robot Collaboration

    Directory of Open Access Journals (Sweden)

    Yuan Yao

    2016-05-01

    Full Text Available When building a 3D printing cloud manufacturing platform, self-sensing and collaboration on manufacturing resources present challenging problems. This paper proposes a peer-robot collaboration framework to deal with these issues. Each robot combines heterogeneous additive manufacturing hardware and software, acting as an intelligent agent. Through collaboration with other robots, it forms a dynamic and scalable integration manufacturing system. The entire distributed system is managed by rules that employ an internal rule engine, which supports rule conversion and conflict resolution. Two additive manufacturing service scenarios are designed to analyse the efficiency and scalability of the framework. Experiments show that the presented method performs well in tasks requiring large-scale access to resources and collaboration.

    Clancy, Robert

    2010-01-01

    A collaborative program between the Papua New Guinea (PNG) Institute of Medical Research and the Hunter Mucosal Group has completed studies relevant to protection of the airways against bacterial infection. Specifically, these studies addressed the mucosal capacity to produce local immunoglobulins and the capacity of the airways to respond to an oral vaccine containing inactivated nontypeable Haemophilus influenzae (NTHi). The mucosal IgA response to NTHi antigens was blunted in both children and adults in PNG compared with that found in Australian children and adults, whose airways are colonized only intermittently. Despite this, when oral NTHi is given to Papua New Guinean adults with chronic airways disease, it is followed by a significant (50%) reduction in incidence of acute bronchitic episodes, and a 3-log reduction in density of colonization, which persisted about 10 months. The implications of these key findings are discussed with respect to both mechanism and wider control of pathology emanating from abnormal airways colonization in a PNG environment. PMID:23163182

    2007-01-01

    Collaborative Resource Allocation Networking Environment (CRANE) Version 0.5 is a prototype created to prove the newest concept of using a distributed environment to schedule Deep Space Network (DSN) antenna times in a collaborative fashion. This program is for all space-flight and terrestrial science project users and DSN schedulers to perform scheduling activities and conflict resolution, both synchronously and asynchronously. Project schedulers can, for the first time, participate directly in scheduling their tracking times into the official DSN schedule, and negotiate directly with other projects in an integrated scheduling system. A master schedule covers long-range, mid-range, near-real-time, and real-time scheduling time frames all in one, rather than the current method of separate functions that are supported by different processes and tools. CRANE also provides private workspaces (both dynamic and static), data sharing, scenario management, user control, rapid messaging (based on Java Message Service), data/time synchronization, workflow management, notification (including emails), conflict checking, and a linkage to a schedule generation engine. The data structure with corresponding database design combines object trees with multiple associated mortal instances and relational database to provide unprecedented traceability and simplify the existing DSN XML schedule representation. These technologies are used to provide traceability, schedule negotiation, conflict resolution, and load forecasting from real-time operations to long-range loading analysis up to 20 years in the future. CRANE includes a database, a stored procedure layer, an agent-based middle tier, a Web service wrapper, a Windows Integrated Analysis Environment (IAE), a Java application, and a Web page interface.

  6. Exploiting Publication Contents and Collaboration Networks for Collaborator Recommendation.

    Directory of Open Access Journals (Sweden)

    Xiangjie Kong

    Full Text Available Thanks to the proliferation of online social networks, it has become conventional for researchers to communicate and collaborate with each other. Meanwhile, one critical challenge arises, that is, how to find the most relevant and potential collaborators for each researcher? In this work, we propose a novel collaborator recommendation model called CCRec, which combines the information on researchers' publications and collaboration network to generate better recommendation. In order to effectively identify the most potential collaborators for researchers, we adopt a topic clustering model to identify the academic domains, as well as a random walk model to compute researchers' feature vectors. Using DBLP datasets, we conduct benchmarking experiments to examine the performance of CCRec. The experimental results show that CCRec outperforms other state-of-the-art methods in terms of precision, recall and F1 score.

    Over the last decades, science has grown increasingly collaborative and interdisciplinary and has come to depart in important ways from the classical analyses of the development of science that were developed by historically inclined philosophers of science half a century ago. In this paper, I shall provide a new account of the structure and development of contemporary science based on analyses of, first, cognitive resources and their relations to domains, and second of the distribution of cognitive resources among collaborators and the epistemic dependence that this distribution implies. On this background I shall describe different ideal types of research activities and analyze how they differ. Finally, analyzing values that drive science towards different kinds of research activities, I shall sketch the main mechanisms underlying the perceived tension between disciplines and interdisciplinarity and argue for a redefinition of accountability and quality control for interdisciplinary and collaborative science.

    2015-05-01

    Dealing with an ever increasing amount of data is a challenge that military intelligence analysts or team of analysts face day to day. Increased individual and collective comprehension goes through collaboration between people. Better is the collaboration, better will be the comprehension. Nowadays, various technologies support and enhance collaboration by allowing people to connect and collaborate in settings as varied as across mobile devices, over networked computers, display walls, tabletop surfaces, to name just a few. A powerful collaboration system includes traditional and multimodal visualization features to achieve effective human communication. Interactive visualization strengthens collaboration because this approach is conducive to incrementally building a mental assessment of the data meaning. The purpose of this paper is to present an overview of the envisioned collaboration architecture and the interactive visualization concepts underlying the Sensemaking Support System prototype developed to support analysts in the context of the Joint Intelligence Collection and Analysis Capability project at DRDC Valcartier. It presents the current version of the architecture, discusses future capabilities to help analyst(s) in the accomplishment of their tasks and finally recommends collaboration and visualization technologies allowing to go a step further both as individual and as a team.

    Full Text Available Recommender Systems are software tools and techniques for suggesting items to users by considering their preferences in an automated fashion. The suggestions provided are aimed at support users in various decision-making processes. Technically, recommender system has their origins in different fields such as Information Retrieval (IR, text classification, machine learning and Decision Support Systems (DSS. Recommender systems are used to address the Information Overload (IO problem by recommending potentially interesting or useful items to users. They have proven to be worthy tools for online users to deal with the IO and have become one of the most popular and powerful tools in E-commerce. Many existing recommender systems rely on the Collaborative Filtering (CF and have been extensively used in E-commerce .They have proven to be very effective with powerful techniques in many famous E-commerce companies. This study presents an overview of the field of recommender systems with current generation of recommendation methods and examines comprehensively CF systems with its algorithms.

  12. Collaborating on Referring Expressions

    CERN Document Server

    Heeman, P A; Heeman, Peter A.; Hirst, Graeme

    1995-01-01

    This paper presents a computational model of how conversational participants collaborate in order to make a referring action successful. The model is based on the view of language as goal-directed behavior. We propose that the content of a referring expression can be accounted for by the planning paradigm. Not only does this approach allow the processes of building referring expressions and identifying their referents to be captured by plan construction and plan inference, it also allows us to account for how participants clarify a referring expression by using meta-actions that reason about and manipulate the plan derivation that corresponds to the referring expression. To account for how clarification goals arise and how inferred clarification plans affect the agent, we propose that the agents are in a certain state of mind, and that this state includes an intention to achieve the goal of referring and a plan that the agents are currently considering. It is this mental state that sanctions the adoption of g...

  14. Taking learning seriously: From competition to collaboration

    International Nuclear Information System (INIS)

    Several nuclear power operations have adopted the strategic goal of acquiring and maintaining the best qualified workforce possible - no small task in the face of recent work-force studies. Many utilities also believe that creating opportunities for employees to acquire knowledge beyond what is required to do their job will increase the level of professionalism of workers. One approach that attests to one's ability to grow beyond and strive for more knowledge is the earning of an accredited college credential. Regents College of the University of the State of New York is illustrative of the nature and success of collaboration between campus-based and external degree programs for adults. A combination of eliminating competition among educational providers, sharing the collective knowledge of training and educational resources, and working with utilities to optimize the fiscal resources available for education is a method that is helping to meet the needs of today's and tomorrow's workforce which works

  16. ICP (ITER Collaborative Platform)

    International Nuclear Information System (INIS)

    The ITER organization has the necessity to manage a massive amount of data and processes. Each team requires different process and databases often interconnected with those of others teams. ICP (ITER Collaborative Platform) is the current central ITER repository of structured and unstructured data. All data in ICP is served and managed via a web interface that provides global accessibility with a common user friendly interface. This paper will explain the model used by ICP and how it serves the ITER project by providing a robust and agile platform. ICP is developed in ASP.NET using MSSQL Server for data storage. It currently houses 15 data driven applications, 150 different types of record, 500 k objects and 2.5 M references. During European working hours the system averages 150 concurrent users and 20 requests per second. ICP connects to external database applications to provide a single entry point to ITER data and a safe shared storage place to maintain this data long-term. The Core model provides an easy to extend framework to meet the future needs of the Organization. ICP follows a multi-tier architecture, providing logical separation of process. The standard three-tier architecture is expanded, with the data layer separated into data storage, data structure, and data access components. The business or applications logic layer is broken up into a common business functionality layer, a type specific logic layer, and a detached work-flow layer. Finally the presentation tier comprises a presentation adapter layer and an interface layer. Each layer is built up from small blocks which can be combined to create a wide range of more complex functionality. Each new object type developed gains access to a wealth of existing code functionality, while also free to adapt and extend this. The hardware structure is designed to provide complete redundancy, high availability and to handle high load. This document is made of the slides of the presentation. (authors)

  17. ICFA on international collaboration

    International Nuclear Information System (INIS)

    International collaboration in high energy physics is what ICFA - the International Committee for Future Accelerators - is all about. Progress is highlighted every three years when ICFA convenes its 'Future Perspectives in High Energy Physics' seminar to focus attention on major issues and to identify evolving trends. The latest such seminar, held at the DESY Laboratory in Hamburg from 3-7 May, looked at international cooperation in the construction of major facilities. Status reports across the whole range of existing experimental programmes and ongoing plans gave valuable pointers to future needs. For electron-positron linear colliders (EPLC), research and development work towards the next generation of machines is underway in Laboratories throughout the world. At previous such seminars, at Tsukuba, Japan (1984), Brookhaven, USA (1987) and Protvino (1990), ICFA, which has no direct power, could sometimes only stand on the sidelines and comment on the emergence of major new national plans. The lessons learnt, ICFA is keen to make sure that the EPLC debut on the world stage will be better choreographed. In addition to plans for new major experimental facilities, the Hamburg seminar also provided a valuable snapshot of the current scene and the directions in which ongoing research is poised to take. This covered existing facilities and projects, 'factories' to mass-produce specific particles, fixed target studies and non-accelerator experiments as well as the key EPLC development theme. B-physics, the study of particles containing the fifth, or 'beauty' (b) quark, emerged as an important thread running across several machine scenarios

  1. Supporting tactical intelligence using collaborative environments and social networking

    Science.gov (United States)

    Wollocko, Arthur B.; Farry, Michael P.; Stark, Robert F.

    2013-05-01

    Modern military environments place an increased emphasis on the collection and analysis of intelligence at the tactical level. The deployment of analytical tools at the tactical level helps support the Warfighter's need for rapid collection, analysis, and dissemination of intelligence. However, given the lack of experience and staffing at the tactical level, most of the available intelligence is not exploited. Tactical environments are staffed by a new generation of intelligence analysts who are well-versed in modern collaboration environments and social networking. An opportunity exists to enhance tactical intelligence analysis by exploiting these personnel strengths, but is dependent on appropriately designed information sharing technologies. Existing social information sharing technologies enable users to publish information quickly, but do not unite or organize information in a manner that effectively supports intelligence analysis. In this paper, we present an alternative approach to structuring and supporting tactical intelligence analysis that combines the benefits of existing concepts, and provide detail on a prototype system embodying that approach. Since this approach employs familiar collaboration support concepts from social media, it enables new-generation analysts to identify the decision-relevant data scattered among databases and the mental models of other personnel, increasing the timeliness of collaborative analysis. Also, the approach enables analysts to collaborate visually to associate heterogeneous and uncertain data within the intelligence analysis process, increasing the robustness of collaborative analyses. Utilizing this familiar dynamic collaboration environment, we hope to achieve a significant reduction of time and skill required to glean actionable intelligence in these challenging operational environments.

    2014-07-01

    Full Text Available The United States Special Operations Command (USSOCOM has emphasized the importance of international SOF collaboration, or what USSOCOM refers to as a “global SOF network.” It is difficult to achieve requisite levels of collaboration even among departments and agencies within a single country, much less on an international basis. Yet USSOCOM has been rightly praised for its trailblazing collaboration efforts in counterterrorism operations, so perhaps it can extend successful collaboration to its “global SOF network.” This article argues collaboration lessons from the past decade of counterterrorism operations can be used to facilitate better international SOF collaboration. Even if the lessons are well recognized they will be hard to act upon, especially when USSOCOM is using its indirect approach to SOF missions managed out of U.S. embassies overseas. But the first step in solving any problem is recognizing the nature of the problem and what is required to solve it. The rest is all disciplined, aggressive and intelligent implementation, which Special Operations Forces do well.

    International collaborations in studies utilizing ground-based space flight analogs are an effective means for answering research questions common to participating agencies. These collaborations bring together worldwide experts to solve important space research questions. By collaborating unnecessary duplication of science is reduced, and the efficiency of analog use is improved. These studies also share resources among agencies for cost effective solutions to study implementation. Recently, NASA has engaged in collaborations with international partners at a variety of analog sites. The NASA Human Exploration Research Analog (HERA) is currently hosting investigator studies from NASA and from the German Space Agency (DLR). These isolation studies will answer questions in the areas of team cohesion, sleep and circadian rhythms, and neurobehavioral correlates to function. Planning for the next HERA campaign is underway as proposal selections are being made from the International Life Sciences Research Announcement (ILSRA). Studies selected from the ILSRA will be conducted across 4 HERA missions in 2017. NASA is planning collaborative studies with DLR at the :envihab facility in Cologne, Germany. Investigations were recently selected to study the effects of 0.5% CO2 exposure over 30 days of bed rest. These studies will help to determine the fidelity of this ground-based analog for studying the visual impairment intracranial pressure syndrome. NASA is also planning a multilateral collaboration at :envihab with DLR and the European Space Agency (ESA) to examine artificial gravity as a countermeasure to mitigate the effects of 60 days of bed rest. NASA is also considering collaborations with the Russian Institute for Biomedical Problems (IBMP) in studies that will utilize their Ground-based Experimental Facility (NEK).

  9. The Roles of Size and Size Difference in Australian and Chinese Inter-firm Collaborations

    Directory of Open Access Journals (Sweden)

    Yu Zhang

    Full Text Available There has been considerable debate on the contribution and significance of firm size to the establishment, operation and success of business collaboration. One important source of this debate arises from differing definitions of firm size used in previous research. This paper uses firm size categories and size differences between collaborating firms to examine their contribution to the formation and performance of inter-firmcollaboration in Australia and China. Both qualitative case study and quantitative data analyses are adopted in this paper. Results from both the qualitative case study and quantitative study in Australia and China show that size plays a significant positive role in the formation and performance of business collaboration. Firmsprefer collaborating with larger partners. Bigger firms are more likely to achieve success collaborations. However, size difference plays a negative role in business collaboration. Collaborating with a bigger partner makes it harder to succeed. On the other hand, size and size difference play very different roles in performanceand outcomes of business collaboration in different countries.This paper compares the roles of firm size and size difference in Australian and Chinese inter-firm collaboration. The results provide important strategic implications for business managers, industry regulators, and policy decision makers regarding international business collaboration.

    Collaborative inquiry learning is one of the most challenging and exciting ventures for today's schools. It aims at bringing a new and promising culture of teaching and learning into the classroom where students in groups engage in self-regulated learning activities supported by the teacher. It is expected that this way of learning fosters students' motivation and interest in science, that they learn to perform steps of inquiry similar to scientists and that they gain knowledge on scientific processes. Starting from general pedagogical reflections and science standards, the article reviews some prominent models of inquiry learning. This comparison results in a set of inquiry processes being the basis for cooperation in the scientific network NetCoIL. Inquiry learning is conceived in several ways with emphasis on different processes. For an illustration of the spectrum, some main conceptions of inquiry and their focuses are described. In the next step, the article describes exemplary computer tools and environments from within and outside the NetCoIL network that were designed to support processes of collaborative inquiry learning. These tools are analysed by describing their functionalities as well as effects on student learning known from the literature. The article closes with challenges for further developments elaborated by the NetCoIL network.

  15. Electronic Commerce and Collaboration Between Competing Firms

    Directory of Open Access Journals (Sweden)

    1998-11-01

    Full Text Available Investments in electronic commerce technology typically require large sums of money and the realisation of possible benefits is often highly uncertain. Possible investors may also be confronted with the so-called free rider-problem. Innovators have to bear all development costs. Once standards are established followers (free riders may easily imitate the investment. Hence, innovators may not be able to build up sustaining competitive advantages that make their investments worthwhile. As a result, available technology may not be used in an efficient way. A typical prisoner's dilemma scenario prevails. Pre-competitive collaboration may be a possible solution to this problem. The term "pre-competitive" refers to the possibility of joint application development and/or sharing of information, knowledge and ability. It should not be confused with collusion which may be legally restricted or even forbidden. The goal of the paper is to analyse whether there are economic incentives for pre-competitive collaboration as sketched above. The analysis is carried out with the help of a microeconomic model and techniques from game theory.

    Collaboration plays an increasingly important role in research productivity and impact. However, it remains unclear whether female and male researchers in science, technology, engineering and mathematical (STEM) disciplines differ significantly from each other in their collaboration propensity. Here, we report on an empirical analysis of the complete publication records of 3,920 faculty members in six STEM disciplines at selected top U.S. research universities. We find that while female faculty have significantly fewer co-authors over their careers, this can be fully explained by their lower number of publications. Indeed, we also find that females tend to distribute their co-authoring opportunities among their co-authors more evenly than males do. Our results suggest that females have had a greater propensity to collaborate, in order to succeed in a historically men-dominated academic world. Surprisingly, we find evidence that in molecular biology there has been a gender segregation within sub-disciplines. Female faculty in molecular biology departments tend to collaborate with smaller teams and publish in journals and fields where typical team size is smaller. Our results identify gender-specific collaborative behaviors as well as disciplines with distinct patterns.

  2. Response Generation in Collaborative Negotiation

    CERN Document Server

    Chu-Carroll, J; Chu-Carroll, Jennifer; Carberry, Sandra

    1995-01-01

    In collaborative planning activities, since the agents are autonomous and heterogeneous, it is inevitable that conflicts arise in their beliefs during the planning process. In cases where such conflicts are relevant to the task at hand, the agents should engage in collaborative negotiation as an attempt to square away the discrepancies in their beliefs. This paper presents a computational strategy for detecting conflicts regarding proposed beliefs and for engaging in collaborative negotiation to resolve the conflicts that warrant resolution. Our model is capable of selecting the most effective aspect to address in its pursuit of conflict resolution in cases where multiple conflicts arise, and of selecting appropriate evidence to justify the need for such modification. Furthermore, by capturing the negotiation process in a recursive Propose-Evaluate-Modify cycle of actions, our model can successfully handle embedded negotiation subdialogues.

    2016-02-01

    Collaboration is a vital process and dominant theme in knowledge production, although the effectiveness of policies directed at promoting multinational research remains ambiguous. We examined approximately 24 million research articles published over four decades and demonstrated that the scaling of international publications to research productivity for each country obeys a universal and conserved sublinear power law. Inefficient mechanisms in transborder team dynamics or organization as well as increasing opportunity costs may contribute to the disproportionate growth of international collaboration rates with increasing productivity among nations. Given the constrained growth of international relationships, our findings advocate a greater emphasis on the qualitative aspects of collaborations, such as with whom partnerships are forged, particularly when assessing research and policy outcomes.

    Wireless energy charging using mobile vehicles has been a viable research topic recently in the area of wireless networks and mobile computing. This paper gives a short survey of recent research conducted in our research group in the area of collaborative mobile charging. In collaborative mobile charging, multiple mobile chargers work together to accomplish a given set of ob jectives. These ob jectives include charging sensors at different frequencies with a minimum number of mobile chargers and reaching the farthest sensor for a given set of mobile chargers, subject to various constraints, including speed and energy limits of mobile chargers. Through the process of problem formulation, solution construction, and future work extension for problems related to collaborative mobile charging and coverage, we present three principles for good practice in conducting research. These principles can potentially be used for assisting graduate students in selecting a research problem for a term project, which can eventually be expanded to a thesis/dissertation topic.

    A variety of possible future analyses of HERA data in the context of the HERA data preservation programme is collected, motivated, and commented. The focus is placed on possible future analyses of the existing $ep$ collider data and their physics scope. Comparisons to the original scope of the HERA programme are made, and cross references to topics also covered by other participants of the workshop are given. This includes topics on QCD, proton structure, diffraction, jets, hadronic final states, heavy flavours, electroweak physics, and the application of related theory and phenomenology topics like NNLO QCD calculations, low-x related models, nonperturbative QCD aspects, and electroweak radiative corrections. Synergies with other collider programmes are also addressed. In summary, the range of physics topics which can still be uniquely covered using the existing data is very broad and of considerable physics interest, often matching the interest of results from colliders currently in operation.

    Full Text Available BACKGROUND: The analysis of co-authorship network aims at exploring the impact of network structure on the outcome of scientific collaborations and research publications. However, little is known about what network properties are associated with authors who have increased number of joint publications and are being cited highly. METHODOLOGY/PRINCIPAL FINDINGS: Measures of social network analysis, for example network centrality and tie strength, have been utilized extensively in current co-authorship literature to explore different behavioural patterns of co-authorship networks. Using three SNA measures (i.e., degree centrality, closeness centrality and betweenness centrality, we explore scientific collaboration networks to understand factors influencing performance (i.e., citation count and formation (tie strength between authors of such networks. A citation count is the number of times an article is cited by other articles. We use co-authorship dataset of the research field of 'steel structure' for the year 2005 to 2009. To measure the strength of scientific collaboration between two authors, we consider the number of articles co-authored by them. In this study, we examine how citation count of a scientific publication is influenced by different centrality measures of its co-author(s in a co-authorship network. We further analyze the impact of the network positions of authors on the strength of their scientific collaborations. We use both correlation and regression methods for data analysis leading to statistical validation. We identify that citation count of a research article is positively correlated with the degree centrality and betweenness centrality values of its co-author(s. Also, we reveal that degree centrality and betweenness centrality values of authors in a co-authorship network are positively correlated with the strength of their scientific collaborations. CONCLUSIONS/SIGNIFICANCE: Authors' network positions in co

    The overall objectives of the project `Feasibility of electricity production from biomass by pressurized gasification systems` within the EC Research Programme JOULE II were to evaluate the potential of advanced power production systems based on biomass gasification and to study the technical and economic feasibility of these new processes with different type of biomass feed stocks. This report was prepared as part of this R and D project. The objectives of this task were to perform fuel analyses of potential woody and herbaceous biomasses with specific regard to the gasification properties of the selected feed stocks. The analyses of 15 Scandinavian and European biomass feed stock included density, proximate and ultimate analyses, trace compounds, ash composition and fusion behaviour in oxidizing and reducing atmospheres. The wood-derived fuels, such as whole-tree chips, forest residues, bark and to some extent willow, can be expected to have good gasification properties. Difficulties caused by ash fusion and sintering in straw combustion and gasification are generally known. The ash and alkali metal contents of the European biomasses harvested in Italy resembled those of the Nordic straws, and it is expected that they behave to a great extent as straw in gasification. Any direct relation between the ash fusion behavior (determined according to the standard method) and, for instance, the alkali metal content was not found in the laboratory determinations. A more profound characterisation of the fuels would require gasification experiments in a thermobalance and a PDU (Process development Unit) rig. (orig.) (10 refs.)

In summary, the range of physics topics which can still be uniquely covered using the existing data is very broad and of considerable physics interest, often matching the interest of results from colliders currently in operation. Due to well-established data and MC sets, calibrations, and analysis procedures the manpower and expertise needed for a particular analysis is often very much smaller than that needed for an ongoing experiment. Since centrally funded manpower to carry out such analyses is not available any longer, this contribution not only targets experienced self-funded experimentalists, but also theorists and master-level students who might wish to carry out such an analysis.

    Recent discussion about the increase in international research collaboration suggests a comprehensive global network centred around a group of core countries and driven by generic socio-economic factors where the global system influences all national and institutional outcomes. In counterpoint, we demonstrate that the collaboration pattern for countries in Africa is far from universal. Instead, it exhibits layers of internal clusters and external links that are explained not by monotypic global influences but by regional geography and, perhaps even more strongly, by history, culture and language. Analysis of these bottom-up, subjective, human factors is required in order to provide the fuller explanation useful for policy and management purposes.

    The steadily increasing quality of hard- and software enables the development of more and more sophisticated groupware. However, modern distributed systems and distributed multimedia systems in particular challenge the abilities of groupware manufacturers, due to the complexity involved in the development of those systems. Frameworks for collaborative environments might provide a solution to these problems, helping to reduce complexity in groupware development by provision of suitable software components. This article will identify the demands and requirements of distributed (multimedia) systems and their human users that frameworks have to take into account. The article then introduces the HOUCOM framework for collaborative environments and sketches the employment of this framework in a sample scenario.

    common tool to answer this question, analysis of log files, faces the problem that the amount of logged data may be overwhelming. This problems gets even worse in the case of insider attacks, where the attacker’s actions usually will be logged as permissible, standard actions—if they are logged at all....... Recent events have revealed intimate knowledge of surveillance and control systems on the side of the attacker, making it often impossible to deduce the identity of an inside attacker from logged data. In this work we present an approach that analyses the access control configuration to identify the set...

  2. Incorporating Brokers within Collaboration Environments

    Science.gov (United States)

    Rajasekar, A.; Moore, R.; de Torcy, A.

    2013-12-01

    A collaboration environment, such as the integrated Rule Oriented Data System (iRODS - http://irods.diceresearch.org), provides interoperability mechanisms for accessing storage systems, authentication systems, messaging systems, information catalogs, networks, and policy engines from a wide variety of clients. The interoperability mechanisms function as brokers, translating actions requested by clients to the protocol required by a specific technology. The iRODS data grid is used to enable collaborative research within hydrology, seismology, earth science, climate, oceanography, plant biology, astronomy, physics, and genomics disciplines. Although each domain has unique resources, data formats, semantics, and protocols, the iRODS system provides a generic framework that is capable of managing collaborative research initiatives that span multiple disciplines. Each interoperability mechanism (broker) is linked to a name space that enables unified access across the heterogeneous systems. The collaboration environment provides not only support for brokers, but also support for virtualization of name spaces for users, files, collections, storage systems, metadata, and policies. The broker enables access to data or information in a remote system using the appropriate protocol, while the collaboration environment provides a uniform naming convention for accessing and manipulating each object. Within the NSF DataNet Federation Consortium project (http://www.datafed.org), three basic types of interoperability mechanisms have been identified and applied: 1) drivers for managing manipulation at the remote resource (such as data subsetting), 2) micro-services that execute the protocol required by the remote resource, and 3) policies for controlling the execution. For example, drivers have been written for manipulating NetCDF and HDF formatted files within THREDDS servers. Micro-services have been written that manage interactions with the CUAHSI data repository, the Data

  3. Scientific collaboration network of Turkey

    International Nuclear Information System (INIS)

    Highlights: • We parsed the 30 years of scientific collaboration data to construct a network. • We made empirical measurements to uncover topological measurements of the network. • The Turkish scientific collaboration network stated out small-world properties. • We also found the degree distribution indicating the network is scale free. • With a high clustering coefficient, the network is a strongly interconnected one. -- Abstract: Networking via co-authorship is an important area of research and used in many fields such as ranking of the universities/departments. Studying on the data supplied by the Web of Science, we constructed a structural database that defines the scientific collaboration network of the authors from Turkey, based on the publications between 1980 and 2010. To uncover the evolution and structure of this complex network by scientific means, we executed some empirical measurements. The Turkish scientific collaboration network is in an accelerating phase in growth, highly governed by the national policies aiming to develop a competitive higher education system in Turkey. As our results suggest the authors tend to make more number of collaborations in their studies over the years. The results also showed that, node separation of the network slightly converges about 4, consistent with the small world phenomenon. Together with this key indicator, the high clustering coefficient, (which is about 0.75) reveals that our network is strongly interconnected. Another quantity of major interest about such networks is, “the degree distribution”. It has a power-law tail that defines the network as scale-free. Along with the final values, the time evolutions of the above-mentioned parameters are presented in detail with this work. In a good agreement with the recent studies, our network yields some significant differences especially in growing rate, clustering properties and node separation. In contrast with the recent studies, we also showed that

    International Nuclear Information System (INIS)

    In 2000 the safety analyses of the Nuclear Regulatory Authority of the Slovak Republic (UJD) were focused on verification of the safety analyses report and probabilistic safety assessment study for NPP V-1 Bohunice after the reconstruction, reviewing of the suggested changes of the Limits and Conditions for NPP V-2 Bohunice and on the assessment of operational events. An important part of work was performed also in solving of scientific and technical tasks appointed within bilateral projects of co-operation between UJD and its international partnerships' organisations, i.e. within international PHARE programme as well as the 5th framework of the European Commission. Verification of safety analyses part of the safety report for NPP V-1 Bohunice after the gradual reconstruction was focused on checking and passing judgement on the completeness of the considered initiating events, safety criteria, input data, adequacy of the used calculation models and also on the overall quality of the submitted documentation. Suitability of the used methodology and the calculation programmes, achieved level of their verification, correctness and interpretation of the results were assessed. The performed review has shown that the checked safety analyses were performed in compliance with the internationally accepted practice, recommendations of UJD and the IAEA. The required level of safety of NPP V-1 Bohunice has been approved. The document with the results and all the findings of the performed review has been prepared. It includes the details of the performed independent calculations, their results and comparison with the results given in the safety report. A special attention was paid to a review of probabilistic safety assessment study of level 1 for NPP Bohunice V-1 after its gradual reconstruction. The probabilistic safety analysis of NPP in full power operation was elaborated in the study and the impact of the gradual reconstruction to the risk decreasing was quantified. The

  6. Uncertainty Analyses and Strategy

    International Nuclear Information System (INIS)

    The DOE identified a variety of uncertainties, arising from different sources, during its assessment of the performance of a potential geologic repository at the Yucca Mountain site. In general, the number and detail of process models developed for the Yucca Mountain site, and the complex coupling among those models, make the direct incorporation of all uncertainties difficult. The DOE has addressed these issues in a number of ways using an approach to uncertainties that is focused on producing a defensible evaluation of the performance of a potential repository. The treatment of uncertainties oriented toward defensible assessments has led to analyses and models with so-called ''conservative'' assumptions and parameter bounds, where conservative implies lower performance than might be demonstrated with a more realistic representation. The varying maturity of the analyses and models, and uneven level of data availability, result in total system level analyses with a mix of realistic and conservative estimates (for both probabilistic representations and single values). That is, some inputs have realistically represented uncertainties, and others are conservatively estimated or bounded. However, this approach is consistent with the ''reasonable assurance'' approach to compliance demonstration, which was called for in the U.S. Nuclear Regulatory Commission's (NRC) proposed 10 CFR Part 63 regulation (64 FR 8640 [DIRS 101680]). A risk analysis that includes conservatism in the inputs will result in conservative risk estimates. Therefore, the approach taken for the Total System Performance Assessment for the Site Recommendation (TSPA-SR) provides a reasonable representation of processes and conservatism for purposes of site recommendation. However, mixing unknown degrees of conservatism in models and parameter representations reduces the transparency of the analysis and makes the development of coherent and consistent probability statements about projected repository

  11. Risk Management Collaboration through Sharing Interactive Graphics

    2010-05-01

    Risk management involves the cooperation of scientists, underwriters and actuaries all of whom analyse data to support decision-making. Results are often disseminated through static documents with graphics that convey the message the analyst wishes to communicate. Interactive graphics are increasingly popular means of communicating the results of data analyses because they enable other parties to explore and visually analyse some of the data themselves prior to and during discussion. Discussion around interactive graphics can occur synchronously in face-to-face meetings or with video-conferencing and screen sharing or they can occur asynchronously through web-sites such as ManyEyes, web-based fora, blogs, wikis and email. A limitation of approaches that do not involve screen sharing is the difficulty in sharing the results of insights from interacting with the graphic. Static images accompanied can be shared but these themselves cannot be interacted, producing a discussion bottleneck (Baker, 2008). We address this limitation by allowing the state and configuration of graphics to be shared (rather than static images) so that a user can reproduce someone else's graphic, interact with it and then share the results of this accompanied with some commentary. HiVE (Slingsby et al, 2009) is a compact and intuitive text-based language that has been designed for this purpose. We will describe the vizTweets project (a 9-month project funded by JISC) in which we are applying these principles to insurance risk management in the context of the Willis Research Network, the world's largest collaboration between the insurance industry and the academia). The project aims to extend HiVE to meet the needs of the sector, design, implement free-available web services and tools and to provide case studies. We will present a case study that demonstrate the potential of this approach for collaboration within the Willis Research Network. Baker, D. Towards Transparency in Visualisation Based

    2006-12-31

    This paper explores the deep roots of closeness that twins share in their youngest age and their effect on their destiny at the adult age. Psychologists believe the bond between twins begins in utero and develops throughout the twins' lives. The four patterns of twinship described show that the twin bond is determined by the quality of parenting that twins receive in their infancy and early childhood. Common problems of adult twins bring about difficulties to adapt in a non-twin world. The nature versus nurture controversy has taken on new life focusing on inter-twin differences and the importance of parent-child interaction as fundamental to the growth and development of personality.

    2009-02-01

    The motivating vision behind Sandia's MENTOR/PAL LDRD project has been that of systems which use real-time psychophysiological data to support and enhance human performance, both individually and of groups. Relevant and significant psychophysiological data being a necessary prerequisite to such systems, this LDRD has focused on identifying and refining such signals. The project has focused in particular on EEG (electroencephalogram) data as a promising candidate signal because it (potentially) provides a broad window on brain activity with relatively low cost and logistical constraints. We report here on two analyses performed on EEG data collected in this project using the SOBI (Second Order Blind Identification) algorithm to identify two independent sources of brain activity: one in the frontal lobe and one in the occipital. The first study looks at directional influences between the two components, while the second study looks at inferring gender based upon the frontal component.

  4. Overview of Sandia National Laboratories and Khlopin Radium Institute collaborative radiological accident consequence analysis efforts

    International Nuclear Information System (INIS)

    In January, 1995 a collaborative effort to improve radiological consequence analysis methods and tools was initiated between the V.G. Khlopin Institute (KRI) and Sandia National Laboratories (SNL). The purpose of the collaborative effort was to transfer SNL's consequence analysis methods to KRI and identify opportunities for collaborative efforts to solve mutual problems relating to the safety of radiochemical facilities. A second purpose was to improve SNL's consequence analysis methods by incorporating the radiological accident field experience of KRI scientists (e.g. the Chernobyl and Kyshtym accidents). The initial collaborative effort focused on the identification of: safety criteria that radiochemical facilities in Russia must meet; analyses/measures required to demonstrate that safety criteria have been met; and data required to complete the analyses/measures identified to demonstrate the safety basis of a facility

Collaborative pharmacy practice (CPP is accordingly evolving within different models including: disease management, medication therapy management, patient centered medical home, and accountable care organizations. Pharmacist roles in these models relate to drug therapy management and include therapy introduction, adjustment, or discontinuation, patient counseling and education, and identification, resolution, and prevention of problems leading to drug interactions and adverse reactions. Most forms of CPP occur with physicians in various settings. Collaborative practice agreements exist in many states in the US and are mentioned in the International Pharmaceutical Federation policy statement. Impetus for CPP comes from health system and economic concerns, as well as from a regulatory push. There are positive examples in community, ambulatory care, and inpatient settings that have well documented protocols, indicators of care, and measurement and reporting of clinical, economic, and patient reported outcomes; however, implementation of the practice is still not widespread. Conceptual and implementation challenges include health professional training, attitudes, confidence and comfort levels, power and communication issues, logistic barriers of time, workload, proximity, resistance to establish and adopt regulations, and importantly, payment models. Some of the attitudinal and perceptual challenges can be mitigated by incorporation of interprofessional concepts and

    2014-04-01

    Full Text Available Over the past years the concept of role in distance education has become a promising construct for analysing and facilitating collaborative processes and outcomes. Designing effective collaborative learning processes is a complex task that can be supported by existing good practices formulated as pedagogical patterns or scripts. Over the past years, the research on technology enhanced learning has shown that collaborative scripts for learning act as mediating artefacts not only designing educational scenarios but also structuring and prescribing roles and activities. Conversely, existing learning systems are not able to provide dynamic role management in the definition and execution of collaborative scripts. This work proposes the application of Social Network Analysis in order to evaluate the expertise level of a learner when he/she is acting, with an assigned role, within the execution of a collaborative script. Semantic extensions to both IMS Learning Design and Information Packaging specifications are also proposed to support roles management.

    Medulloblastoma has variable appearances on MRI in both children and adults. Adults are more likely to have heterogeneous cerebellar hemisphere tumours, and this is thought to be related to the greater prevalence of desmoplastic tumours in adulthood. Few studies have addressed the MRI features of adult medulloblastoma and the specific characteristics of desmoplastic and classic tumours have not been analysed. Our aim was to analyse the imaging characteristics of desmoplastic (DM) and classic (CM) medulloblastomas in adult. We retrospectively studied preoperative MRI of six men and three women, median age 33 years, range 23-53 years, with pathologically proved medulloblastomas. There were six (67%) with DM. The tumour was in the cerebellar hemisphere in eight patients (89%), including the three with CM, one of which was bilateral. All tumours were heterogeneous, giving predominantly low or isointense signal on T1- and isointense signal on T2-weighted images. Cystic or necrotic areas in all patients were particularly visible on T2-weighted images. Contrast enhancement was absent in one DM and varied from slight to intense in eight (three CM), homogeneous in one DM and patchy in seven. All tumours extended to the surface of the cerebellum and two had well-defined margins. MRI does not allow a clear distinction between DM and CM in adults. (orig.)

Understanding how to use the powerful learning techniques involved in collaborative learning in an online context is imperative. In this article, the focus is based on the importance of collaboration in online instructions. The major concerns are centering on the following questions: What is Collaboration? Why choose collaboration as a strategy? What collaboration tools are commonly used online? This paper will also examine the techniques used to facilitate good collaboration and the proper implementation of collaborative online discussions.

    Collaborative partnerships between community-based clinicians and academic researchers have the potential to improve the relevance, utility, and feasibility of research, as well as the effectiveness of practice. Collaborative partnership research from a variety of fields can inform the development and maintenance of effective partnerships. In this paper we present a conceptual model of research-community practice partnership derived from literature across disciplines and then illustrate application of this model to one case example. The case example is a multi-year partnership between an interdisciplinary group of community-based psychotherapists and a team of mental health researchers. This partnership was initiated to support federally funded research on community-based outpatient mental health care for children with disruptive behavior problems, but it has evolved to drive and support new intervention studies with different clinical foci. Lessons learned from this partnership process will be shared and interpreted in the context of the presented research-practice partnership model. PMID:24224554

  5. Comparative analysis of collaboration networks

    In this paper we carry out a comparative analysis of the word network as the collaboration network based on the novel by M. Bulgakov 'Master and Margarita', the synonym network of the Russian language as well as the Russian movie actor network. We have constructed one-mode projections of these networks, defined degree distributions for them and have calculated main characteristics. In the paper a generation algorithm of collaboration networks has been offered which allows one to generate networks statistically equivalent to the studied ones. It lets us reveal a structural correlation between word network, synonym network and movie actor network. We show that the degree distributions of all analyzable networks are described by the distribution of q-type.

  12. Fermilab-Latin America collaboration

    International Nuclear Information System (INIS)

    Fermilab's program of collaboration with Latin America was initiated by then-Director Leon Lederman about 1980. His goal was to aid Latin American physics, and particularly its particle physics; this latter aim is in keeping with the Laboratory's particle physics mission. The reasons for collaboration between institutions in the US and Latin America are many, including geographic and cultural, together with the existence of many talented scientists and many centers of excellence in the region. There are also broader reasons; for example, it has been stated frequently that physics is the basis of much technology, and advanced technology is a necessity for a country's development. There is nothing unique about Fermilab's program; other US institutions can carry out similar activities, and some have carried out individual items in the past. On the Latin American side, such collaboration enables institutions there to carry out forefront physics research, and also to have the advantages of particle physics spin-offs, both in expertise in related technologies and in scientist training. In addition to particle physics, collaboration is possible in many other related areas. Although particle physics is frequently viewed as open-quotes big scienceclose quotes, all of the large research groups in the field are composed of many small university groups, each of which contributes to the experiment, the analysis and the physics. Fermilab is an international laboratory, open to all users; a research proposal is accepted on scientific merit and technical competence, not on the country of origin of the scientists making the proposal. Currently, of Fermilab's approximately 1400 users, about 30% are from non-US institutions. It should be noted here that Fermilab's funds, which come from the US government, are for particle physics only; however, there is some flexibility in interpretation of this

  17. The collaborative roots of corruption.

    Weisel, Ori; Shalvi, Shaul

    2015-08-25

    Cooperation is essential for completing tasks that individuals cannot accomplish alone. Whereas the benefits of cooperation are clear, little is known about its possible negative aspects. Introducing a novel sequential dyadic die-rolling paradigm, we show that collaborative settings provide fertile ground for the emergence of corruption. In the main experimental treatment the outcomes of the two players are perfectly aligned. Player A privately rolls a die, reports the result to player B, who then privately rolls and reports the result as well. Both players are paid the value of the reports if, and only if, they are identical (e.g., if both report 6, each earns €6). Because rolls are truly private, players can inflate their profit by misreporting the actual outcomes. Indeed, the proportion of reported doubles was 489% higher than the expected proportion assuming honesty, 48% higher than when individuals rolled and reported alone, and 96% higher than when lies only benefited the other player. Breaking the alignment in payoffs between player A and player B reduced the extent of brazen lying. Despite player B's central role in determining whether a double was reported, modifying the incentive structure of either player A or player B had nearly identical effects on the frequency of reported doubles. Our results highlight the role of collaboration-particularly on equal terms-in shaping corruption. These findings fit a functional perspective on morality. When facing opposing moral sentiments-to be honest vs. to join forces in collaboration-people often opt for engaging in corrupt collaboration. PMID:26261341

    The Advanced Engineering Environment (AEE) is a model for an engineering design and communications system that will enhance project collaboration throughout the nuclear weapons complex (NWC). Sandia National Laboratories and Parametric Technology Corporation (PTC) worked together on a prototype project to evaluate the suitability of a portion of PTC's Windchill 9.0 suite of data management, design and collaboration tools as the basis for an AEE. The AEE project team implemented Windchill 9.0 development servers in both classified and unclassified domains and used them to test and evaluate the Windchill tool suite relative to the needs of the NWC using weapons project use cases. A primary deliverable was the development of a new real time collaborative desktop design and engineering process using PDMLink (data management tool), Pro/Engineer (mechanical computer aided design tool) and ProductView Lite (visualization tool). Additional project activities included evaluations of PTC's electrical computer aided design, visualization, and engineering calculations applications. This report documents the AEE project work to share information and lessons learned with other NWC sites. It also provides PTC with recommendations for improving their products for NWC applications.

A key area of VCE and VCC research is in shared visualization of virtual environments. This paper describes a Virtual Collaborative Visualizer (VCV), named Rocinante, that Sandia developed for VCE and VCC applications. Rocinante allows multiple participants to simultaneously view dynamic geometrically-defined environments. Each viewer can exclude extraneous detail or include additional information in the scene as desired. Shared information can be saved and later replayed in a stand-alone mode. Rocinante automatically scales visualization requirements with computer system capabilities. Models with 30,000 polygons and 4 Megabytes of texture display at 12 to 15 frames per second (fps) on an SGI Onyx and at 3 to 8 fps (without texture) on Indigo 2 Extreme computers. In its networked mode, Rocinante synchronizes its local geometric model with remote simulators and sensory systems by monitoring data transmitted through UDP packets.

    This study presents results from a collaboration across five longitudinal studies seeking to test and replicate models of gene-environment interplay in the development of substance use and externalizing disorders (SUDs, EXT). We describe an overview of our conceptual models, plan for gene-environment interplay analyses, and present main effects results evaluating six candidate genes potentially relevant to SUDs and EXT (MAOA, 5-HTTLPR, COMT, DRD2, DAT1, and DRD4). All samples included rich longitudinal and phenotypic measurements from childhood/adolescence (ages 5-13) through early adulthood (ages 25-33); sample sizes ranged from 3487 in the test sample, to ~600-1000 in the replication samples. Phenotypes included lifetime symptom counts of SUDs (nicotine, alcohol and cannabis), adult antisocial behavior, and an aggregate externalizing disorder composite. Covariates included the first 10 ancestral principal components computed using all autosomal markers in subjects across the data sets, and age at the most recent assessment. Sex, ancestry, and exposure effects were thoroughly evaluated. After correcting for multiple testing, only one significant main effect was found in the test sample, but it was not replicated. Implications for subsequent gene-environment interplay analyses are discussed. PMID:27444553

    This paper presents an attempt to enhance the role of local stakeholders in dealing with urban floods. The concept is based on the DIANE-CM project (Decentralised Integrated Analysis and Enhancement of Awareness through Collaborative Modelling and Management of Flood Risk) of the ERANET CRUE programme. The main objective of the project was to develop and test the advanced methodology for enhancing the resilience of the local communities to flooding by a participative and interactive approach. Through collaborative modelling, a social learning process was initiated which will enhance the social capacity of the stakeholders due to the interaction process. The other aim of the project was to better understand how data from hazard and vulnerability analyses and improved maps, as well as from the near real time flood prediction, can be used to initiate a public dialogue (i.e. collaborative mapping and planning activities) in order to carry out more informed and shared decision making processes and to enhance flood risk awareness - which will improve the flood resilience situation. The concept of collaborative modelling was applied in two case studies: (1) the Roding river/Cranbrook catchment in the UK, with focus on pluvial flooding, and (2) the Alster catchment in Germany, with focus on fluvial flooding.

    The Venus Exploration Analysis Group (VEXAG) was established by NASA in July 2005 to identify scientific priorities and strategy for exploration of Venus. From the outset, VEXAG has been open to the international community participation and has followed the progress of the ESA Venus Express Mission and the JAXA Akasuki mission as well exploring potential broad international partnerships for Venus exploration through coordinated science and missions. This paper discussed three mechanisms through which these collaborations are being explored in which VEXAG members participate One pathway for international collaboration has been through COSPAR. The International Venus Exploration Working Group (IVEWG) was formed during the 2012 COSPAR general assembly in Mysore, India. Another potentially significant outcome has been the IVEWG’s efforts to foster a formal dialog between IKI and NASA/PSD on the proposed Venera D mission resulting in a meeting in June 2013 to be followed by a discussion at the 4MS3 conference in October 2013. This has now resulted in an agreement between NASA/PSD and IKI to form a joint Science Definition Team for Venera D. A second pathway has been through an international focus on comparative climatology. Scientists from the established space faring nations participated in a first international conference on Comparative Climatology for Terrestrial Planet (CCTP) in Boulder Colorado in June 2012 sponsored by several international scientific organizations. A second conference is planned for 2015. The Planetary Robotics Exploration Coordinating Group (PRECG) of International Academy of Astronautics (IAA) the IAA has been focusing on exploring affordable contributions to the robotic exploration by non-space-faring nations wishing to get involved in planetary exploration. PRECG has sponsored a two year study of Comparative Climatology for which Venus is the focal point and focused on engaging nations without deep space exploration capabilities. A third

    A methodology for designing operational facilities for collaboration by multiple experts has begun to take shape as an outgrowth of a project to design such facilities for scientific operations of the planned 2003 Mars Exploration Rover (MER) mission. The methodology could also be applicable to the design of military "situation rooms" and other facilities for terrestrial missions. It was recognized in this project that modern mission operations depend heavily upon the collaborative use of computers. It was further recognized that tests have shown that layout of a facility exerts a dramatic effect on the efficiency and endurance of the operations staff. The facility designs (for example, see figure) and the methodology developed during the project reflect this recognition. One element of the methodology is a metric, called effective capacity, that was created for use in evaluating proposed MER operational facilities and may also be useful for evaluating other collaboration spaces, including meeting rooms and military situation rooms. The effective capacity of a facility is defined as the number of people in the facility who can be meaningfully engaged in its operations. A person is considered to be meaningfully engaged if the person can (1) see, hear, and communicate with everyone else present; (2) see the material under discussion (typically data on a piece of paper, computer monitor, or projection screen); and (3) provide input to the product under development by the group. The effective capacity of a facility is less than the number of people that can physically fit in the facility. For example, a typical office that contains a desktop computer has an effective capacity of .4, while a small conference room that contains a projection screen has an effective capacity of around 10. Little or no benefit would be derived from allowing the number of persons in an operational facility to exceed its effective capacity: At best, the operations staff would be underutilized

  20. Collaborative Clustering for Sensor Networks

    2011-01-01

    Traditionally, nodes in a sensor network simply collect data and then pass it on to a centralized node that archives, distributes, and possibly analyzes the data. However, analysis at the individual nodes could enable faster detection of anomalies or other interesting events, as well as faster responses such as sending out alerts or increasing the data collection rate. There is an additional opportunity for increased performance if individual nodes can communicate directly with their neighbors. Previously, a method was developed by which machine learning classification algorithms could collaborate to achieve high performance autonomously (without requiring human intervention). This method worked for supervised learning algorithms, in which labeled data is used to train models. The learners collaborated by exchanging labels describing the data. The new advance enables clustering algorithms, which do not use labeled data, to also collaborate. This is achieved by defining a new language for collaboration that uses pair-wise constraints to encode useful information for other learners. These constraints specify that two items must, or cannot, be placed into the same cluster. Previous work has shown that clustering with these constraints (in isolation) already improves performance. In the problem formulation, each learner resides at a different node in the sensor network and makes observations (collects data) independently of the other learners. Each learner clusters its data and then selects a pair of items about which it is uncertain and uses them to query its neighbors. The resulting feedback (a must and cannot constraint from each neighbor) is combined by the learner into a consensus constraint, and it then reclusters its data while incorporating the new constraint. A strategy was also proposed for cleaning the resulting constraint sets, which may contain conflicting constraints; this improves performance significantly. This approach has been applied to collaborative

  6. Supporting Dynamic Ad hoc Collaboration Capabilities

    International Nuclear Information System (INIS)

    Modern HENP experiments such as CMS and Atlas involve as many as 2000 collaborators around the world. Collaborations this large will be unable to meet often enough to support working closely together. Many of the tools currently available for collaboration focus on heavy-weight applications such as videoconferencing tools. While these are important, there is a more basic need for tools that support connecting physicists to work together on an ad hoc or continuous basis. Tools that support the day-to-day connectivity and underlying needs of a group of collaborators are important for providing light-weight, non-intrusive, and flexible ways to work collaboratively. Some example tools include messaging, file-sharing, and shared plot viewers. An important component of the environment is a scalable underlying communication framework. In this paper we will describe our current progress on building a dynamic and ad hoc collaboration environment and our vision for its evolution into a HENP collaboration environment

  8. Cross-Disciplinary Collaboration and Learning

    Full Text Available Complex environmental problem solving depends on cross-disciplinary collaboration among scientists. Collaborative research must be preceded by an exploratory phase of collective thinking that creates shared conceptual frameworks. Collective thinking, in a cross-disciplinary setting, depends on the facility with which collaborators are able to learn and understand each others' perspectives. This paper applies three perspectives on learning to the problem of enabling cross-disciplinary collaboration: Maslow's hierarchy of needs, constructivism, and organizational learning. Application of learning frameworks to collaboration provides insights regarding receptive environments for collaboration, and processes that facilitate cross-disciplinary interactions. These environments and interactions need time to develop and require a long phase of idea generation preceding any focused research effort. The findings highlight that collaboration is itself a complex system of people, scientific theory, and tools that must be intentionally managed. Effective management of the system requires leaders who are facilitators and are capable of orchestrating effective environments and interactions.

Even science is changing, along with the processes involving the communication, collaboration and cooperation created through the web, yet rooted in some of its historical features of openness. For this issue, JCOM has asked some experts on the most recent changes in science to analyse the potential and the contradictions lying in online collaborative science. The new open science feeds on the opportunity to freely contribute to knowledge production, sharing not only data, but also software and hardware. But it is open also to the outside, where citizens use Web 2.0 instruments to discuss about science in a horizontal way.

  13. Visual analytics for aviation safety: A collaborative approach to sensemaking

    Science.gov (United States)

    Wade, Andrew

    Visual analytics, the "science of analytical reasoning facilitated by interactive visual interfaces", is more than just visualization. Understanding the human reasoning process is essential for designing effective visualization tools and providing correct analyses. This thesis describes the evolution, application and evaluation of a new method for studying analytical reasoning that we have labeled paired analysis. Paired analysis combines subject matter experts (SMEs) and tool experts (TE) in an analytic dyad, here used to investigate aircraft maintenance and safety data. The method was developed and evaluated using interviews, pilot studies and analytic sessions during an internship at the Boeing Company. By enabling a collaborative approach to sensemaking that can be captured by researchers, paired analysis yielded rich data on human analytical reasoning that can be used to support analytic tool development and analyst training. Keywords: visual analytics, paired analysis, sensemaking, boeing, collaborative analysis.

The functionality of NetLab is demonstrated by an example of a remote experiment.

  15. Evolution of Scientific Collaboration Network Driven by Homophily and Heterophily

    2015-01-01

    Many scientific collaboration networks exhibit clear community and small world structures. However, the studies on the underlying mechanisms for the formation and evolution of community and small world structures are still insufficient. The mechanisms of homophily and heterophily based on scholars' traits are two important factors for the formation of community and inter-communal links, which may deserve further exploration. In this paper, a multi-agent model, which is based on combinatorial effects of homophily and heterophily, is developed to investigate the evolution of scientific collaboration networks. The simulation results indicate that agents with similar traits aggregate to form community by homophily, while heterophily plays a major role in the formation of inter-communal links. The pattern of network evolution revealed in simulations is essentially consistent with what is observed in empirical analyses, as in both cases the giant component evolves from a small cluster to a structure of chained-comm...

However, our current means of dealing with such challenges has fallen short, and ingenious solutions are required to overcome the inherent resistance to progress toward ameliorating such difficulties. Here, we highlight the promises and challenges of international collaboration in achieving success toward these trials. We note prior successes in fields such as education, medicine, science, and environmental issues made to date, yet at the same time we do note deficiencies and shortcomings in these efforts. Hence, the notion of international collaboration should be strengthened and encouraged by governments, non-profit organizations, and others moving forward using creative

    2009-01-01

    Complete and up-to-date documentation is essential for efficient data analysis in a large and complex collaboration like CMS. Good documentation reduces the time spent in problem solving for users and software developers. The scientists in our research environment do not necessarily have the interests or skills of professional technical writers. This results in inconsistencies in the documentation. To improve the quality, we have started a multidisciplinary project involving CMS user support and expertise in technical communication from the University of Turku, Finland. In this paper, we present possible approaches to study the usability of the documentation, for instance, usability tests conducted recently for the CMS software and computing user documentation
