Sample records for common dab limanda

  1. First isolation of Vibrio tapetis and an atypical strain of Aeromonas salmonicida from skin ulcerations in common dab (Limanda limanda) in the North Sea. (United States)

    Vercauteren, M; De Swaef, E; Declercq, A; Bosseler, L; Gulla, S; Balboa, S; Romalde, J L; Devriese, L; Polet, H; Boyen, F; Chiers, K; Decostere, A


    Skin ulcerations rank amongst the most prevalent lesions affecting wild common dab (Limanda limanda) with an increase in prevalence of up to 3.5% in the Belgian part of the North Sea. A complex aetiology of these ulcerations is suspected, and many questions remain on the exact factors contributing to these lesions. To construct the aetiological spectrum of skin ulcerations in flatfish, a one-day monitoring campaign was undertaken in the North Sea. Fifteen fish presented with one or more ulcerations on the pigmented and/or non-pigmented side. Pathological features revealed various stages of ulcerations with loss of epidermal and dermal tissue, inflammatory infiltrates and degeneration of the myofibers bordering the ulceration, albeit in varying degrees. Upon bacteriological examination, pure cultures of Vibrio tapetis were retrieved in high numbers from five fish and of Aeromonas salmonicida in one fish. The V. tapetis isolates showed cross-reactivity with the sera against the representative strain of serotype O2 originating form a carpet-shell clam (Ruditapes descussatus). Moreover, the A. salmonicida isolates displayed a previously undescribed vapA gene sequence (A-layer type) with possible specificity towards common dab. Further research is necessary to pinpoint the exact role of these agents in the development of skin ulcerations in common dab. © 2017 John Wiley & Sons Ltd.

  2. Spatial and temporal analysis of the risks posed by polychlorinated biphenyl and metal contaminants in dab (Limanda limanda) collected from waters around England and Wales. (United States)

    Nicolaus, E E Manuel; Wright, Serena R; Bolam, Thi P C; Barber, Jonathan L; Bignell, John P; Lyons, Brett P


    The metals cadmium, mercury and lead, and the ICES7 CB levels were analysed in the common dab Limanda limanda to investigate whether concentrations of these determinants are at levels above established OSPAR assessment criteria around England and Wales. The results indicate that CB118 is above the OSPAR derived EAC at 22 out of 29 sampled stations, with 15 showing significant reductions. Cadmium is increasing significantly at six stations with two sites in the North Sea breaching corresponding OSPAR EAC. Mean results for all other PCBs and metals stayed below the EAC thresholds, with Hg concentrations even falling below BAC levels at South Eddystone located in the western English Channel. This study shows that PCBs banned over 20years ago are still found at concentrations in fish liver tissues which may pose a health risk to both the individual fish and their predators.

  3. Sexual differences in food intake, digestive tract size, and growth performance of the dab, Limanda limanda L. (United States)

    Lozán, JoséLuis

    Sexual dimorphism in food intake, size of the digestive tract, hepatosomatic index and respiration were studied in dab from the southeastern North Sea both in the field and the laboratory, in order to explain observed differences in growth. The results show that the food intake of females is significantly greater than that of males. In a tank experiment 20-cm-long females consumed 73% more food than similar-sized males. Studies of deep-frozen samples caught during the main feeding period in August revealed that females contained 1.5 times as much food as males. Females appeared to have a significantly larger digestive tract than males determined on a dry-weight basis. During autumn and winter, females had heavier livers than males. No significant differences were found in the oxygen consumption rate.

  4. A DAB Converter with Common-Point-Connected Winding Transformers Suitable for a Single-Phase 5-Level SST System

    Directory of Open Access Journals (Sweden)

    Hyeok-Jin Yun


    Full Text Available One of the main disadvantages of the multi-level solid-state transformer (SST system is the voltage imbalance on the output of the rectifier modules. This voltage imbalance can be caused by parameter mismatch of the active and passive components, different loads, and the floating structure of the high voltage DC-links. Some studies have been done to solve this voltage imbalance problem. A common way to avoid this imbalance is to balance the voltage of DC-links at the AC/DC conversion stage and balance the power between the modules at the DC/DC conversion stage. Most of these methods require a complex balancing controller or additional circuits. This paper proposes a novel dual active bridge (DAB converter specialized in power balancing in a single-phase 5-level SST system. The proposed DAB converter does not require any additional balancing controllers or techniques for power balancing. The performance of the proposed DAB converter was verified by simulation and experiments using a 3 kW 5-level SST prototype system.

  5. Oxidative drug metabolizing enzymes in North Sea dab (Limanda limanda). Biological effects of pollutants

    Vobach, M.; Kellermann, H.J.


    Increasing environmental pollution is regarded as an anthropogenic stress factor in general. As a consequence, this may have several detrimental impacts on organisms, including aquatic species. The ability of organisms to tolerate stress from chemical pollutants depends on the availability of a variety of protection mechanisms. One important mechanism to protect cells from lipophilic xenobiotics is based on enzymes or enzyme systems converting the chemicals into more polar metabolites which can be excreted

    Full Text Available Er DAB (Digital Audio Broadcast den revolution af radiomediet som det ofte er blevet påstået? I sin analyse af DAB forholder Carin Åberg sig kritisk til den måde DAB og det europæiske forskningsprojekt i di- gital distributionsteknik EUREKA-147 har været markedsført på, bl.a. med mulighed for at selv at sammensætte sit program, forme den lyd- profil man ønsker, modtage hi-fi lyd på højde med bedste cd-kvalitet uden interferens, kombinere lyd, tekst og billeder, og at få en række nye tjenester og et nærmest ubegrænset antal kanaler. I artiklen for- søger Carin Åberg at bestemme nærmere hvori det nye ved DAB egentlig består og hun diskuterer især, hvorvidt teknologien eller de potentielle brugsværdier er drivkraften i udviklingen og hvorvidt ind- førelsen af DAB i den sidste ende kan få fatale konsekvenser for radiomediet som vi kender det i dag.

    Krauss, Melissa J; Sowles, Shaina J; Mylvaganam, Shalinee; Zewdie, Kidist; Bierut, Laura J; Cavazos-Rehg, Patricia A


    Dabbing involves heating marijuana extracts to a high temperature and inhaling the vapor. Little is known about this new method of using marijuana. YouTube, the most popular platform for sharing online videos, may be a go-to resource for individuals interested in learning about dabbing. Our objective was to explore the content of dabbing-related videos on YouTube. We searched for dabbing-related videos on YouTube using the search terms "dabbing" and "dabs" on January 22, 2015. For each term, videos were sorted by relevance and view count. A sample of 116 dabbing videos were viewed and coded for content. The 116 videos (published by 75 unique channels) had a total of 9,545,482 views. Most (76%) of the channels had a specific focus on marijuana and 23% were located in California. Eighty-nine percent of the videos showed at least one person dabbing, and 61% of these showed someone dabbing repeatedly. Most dabbers were male (67%) and many appeared to be >25 years old (42%). Approximately 34% of the videos contained a product review, 28% provided instructions on dabbing or other educational information, and 21% contained at least a brief cautionary message. Over half (54%) of the videos referenced medical marijuana, and only 20% of the videos had an age-restriction. Dabbing-related videos are easily found and can be readily viewed on YouTube. As marijuana use becomes more accepted by the general population, the popularity of dabbing-related videos could increase, potentially normalizing this potent form of marijuana use.

    Gilski Przemysław


    Full Text Available In the age of digital media, delivering broadcast content to customers at an acceptable level of quality is one of the most challenging tasks. The most important factor is the efficient use of available resources, including bandwidth. An appropriate way of managing the digital multiplex is essential for both the economic and technical issues. In this paper we describe transmission quality measurements in the DAB+ broadcast system. We provide a methodology for analysing parameters and factors related with the efficiency and reliability of a digital radio link. We describe a laboratory stand that can be used for transmission quality assessment on a regional and national level.

  11. Sensorimotor learning in Dab1(scm) (scrambler) mutant mice. (United States)

    Lalonde, R; Strazielle, C


    Homozygous Dab1(scm) mouse mutants with cell ectopias in cerebellar cortex and neocortex were compared with non-ataxic controls on two tests of motor coordination: rotorod and grid climbing. Even at the minimal speed of 4 rpm and unlike controls, none of the Dab1(scm) mutants reached criterion on the constant speed rotorod. In contrast, Dab1(scm) mutants improved their performances on the vertical grid over the course of the same number of trials. Thus, despite massive cerebellar degeneration, sensorimotor learning for equilibrium is still possible, indicating the potential usefulness of the grid-climbing test in determining residual functions in mice with massive cerebellar damage.

  12. Automated approach to detecting behavioral states using EEG-DABS

    Directory of Open Access Journals (Sweden)

    Zachary B. Loris


    Full Text Available Electrocorticographic (ECoG signals represent cortical electrical dipoles generated by synchronous local field potentials that result from simultaneous firing of neurons at distinct frequencies (brain waves. Since different brain waves correlate to different behavioral states, ECoG signals presents a novel strategy to detect complex behaviors. We developed a program, EEG Detection Analysis for Behavioral States (EEG-DABS that advances Fast Fourier Transforms through ECoG signals time series, separating it into (user defined frequency bands and normalizes them to reduce variability. EEG-DABS determines events if segments of an experimental ECoG record have significantly different power bands than a selected control pattern of EEG. Events are identified at every epoch and frequency band and then are displayed as output graphs by the program. Certain patterns of events correspond to specific behaviors. Once a predetermined pattern was selected for a behavioral state, EEG-DABS correctly identified the desired behavioral event. The selection of frequency band combinations for detection of the behavior affects accuracy of the method. All instances of certain behaviors, such as freezing, were correctly identified from the event patterns generated with EEG-DABS. Detecting behaviors is typically achieved by visually discerning unique animal phenotypes, a process that is time consuming, unreliable, and subjective. EEG-DABS removes variability by using defined parameters of EEG/ECoG for a desired behavior over chronic recordings. EEG-DABS presents a simple and automated approach to quantify different behavioral states from ECoG signals.

  13. Tracking Dabbing Using Search Query Surveillance: A Case Study in the United States. (United States)

    Zhang, Zhu; Zheng, Xiaolong; Zeng, Daniel Dajun; Leischow, Scott J


    Dabbing is an emerging method of marijuana ingestion. However, little is known about dabbing owing to limited surveillance data on dabbing. The aim of the study was to analyze Google search data to assess the scope and breadth of information seeking on dabbing. Google Trends data about dabbing and related topics (eg, electronic nicotine delivery system [ENDS], also known as e-cigarettes) in the United States between January 2004 and December 2015 were collected by using relevant search terms such as "dab rig." The correlation between dabbing (including topics: dab and hash oil) and ENDS (including topics: vaping and e-cigarette) searches, the regional distribution of dabbing searches, and the impact of cannabis legalization policies on geographical location in 2015 were analyzed. Searches regarding dabbing increased in the United States over time, with 1,526,280 estimated searches during 2015. Searches for dab and vaping have very similar temporal patterns, where the Pearson correlation coefficient (PCC) is .992 (Pmarijuana legalization than in the states with only medical marijuana legalization (P=.02) or the states without medical and recreational marijuana legalization (P=.01). Public interest in dabbing is increasing in the United States. There are close associations between dabbing and ENDS searches. The findings suggest greater popularity of dabs in the states that legalized medical and recreational marijuana use. This study proposes a novel and timely way of cannabis surveillance, and these findings can help enhance the understanding of the popularity of dabbing and provide insights for future research and informed policy making on dabbing.

  14. Cannabis-induced psychosis associated with high potency "wax dabs". (United States)

    Pierre, Joseph M; Gandal, Michael; Son, Maya


    With mounting evidence that the risk of cannabis-induced psychosis may be related to both dose and potency of tetrahydrocannbinol (THC), increasing reports of psychosis associated with cannabinoids containing greater amounts of THC are anticipated. We report two cases of emergent psychosis after using a concentrated THC extract known as cannabis "wax," "oil," or "dabs" raising serious concerns about its psychotic liability. Although "dabbing" with cannabis wax is becoming increasingly popular in the US for both recreational and "medicinal" intentions, our cases raise serious concerns about its psychotic liability and highlight the importance of understanding this risk by physicians recommending cannabinoids for purported medicinal purposes.

  15. Effect of DAB(389)IL-2 immunotoxin on the course of experimental autoimmune encephalomyelitis in Lewis rats. (United States)

    Phillips, S Michael; Bhopale, Mahendra K; Constantinescu, Cris S; Ciric, Bogoljub; Hilliard, Brendan; Ventura, Elvira; Lavi, Ehud; Rostami, Abdolmohamad


    Activated T cells express the high affinity interleukin 2 receptor (IL-2R also CD25) that binds interleukin 2 (IL-2) and transduces signals important for the proliferation and survival of these cells. We investigated the effect of the genetically engineered immunotoxin DAB(389)IL-2 on experimental autoimmune encephalomyelitis (EAE), an autoimmune disease of the central nervous system (CNS) mediated by activated myelin-reactive T cells. EAE is the most commonly used animal model of the human disease multiple sclerosis (MS). DAB(389)IL-2 is a recombinant fusion product made of a portion of diphtheria toxin, which contains binding and translocation components of the toxin linked to IL-2. The diphtheria toxin targets and kills cells expressing the high affinity IL-2 receptor and has been successfully used in several autoimmune and neoplastic conditions. We observed a significant suppression of guinea-pig spinal cord homogenate (gpSCH)-MBP induced active EAE in Lewis rats at 2 x 1,600 kU of DAB(389)IL-2 given on days 7 and 9 post-immunization and complete suppression with the same dose on days 7, 8 and 9 or 7, 8, 9 and 10 after immunization during the active disease period. There were reduced mononuclear cell infiltrates of CD4(+), CD8(+), CD25(+) and alphabetaTCR(+) T cells in the spinal cord of treated rats. However, treatment at day 11 or 12 post-immunization led to severe, fatal disease. The toxin added to cultures in vitro or injected in vivo suppressed antigen- and mitogen-induced T cell proliferation. DAB(389)IL-2 treatment in vivo or exposure of encephalitogenic T cells in vitro prior to transfer did have a significant inhibitory effect on adoptive transfer EAE. Our data demonstrate that DAB(389)IL-2 immunotoxin can suppress active and passive EAE if applied at specific, early time points, but can have negative consequences at later time points.

  16. Control Strategies for the DAB Based PV Interface System.

    Directory of Open Access Journals (Sweden)

    Hadi M El-Helw

    Full Text Available This paper presents an interface system based on the Dual Active Bridge (DAB converter for Photovoltaic (PV arrays. Two control strategies are proposed for the DAB converter to harvest the maximum power from the PV array. The first strategy is based on a simple PI controller to regulate the terminal PV voltage through the phase shift angle of the DAB converter. The Perturb and Observe (P&O Maximum Power Point Tracking (MPPT technique is utilized to set the reference of the PV terminal voltage. The second strategy presented in this paper employs the Artificial Neural Network (ANN to directly set the phase shift angle of the DAB converter that results in harvesting maximum power. This feed-forward strategy overcomes the stability issues of the feedback strategy. The proposed PV interface systems are modeled and simulated using MATLAB/SIMULINK and the EMTDC/PSCAD software packages. The simulation results reveal accurate and fast response of the proposed systems. The dynamic performance of the proposed feed-forward strategy outdoes that of the feedback strategy in terms of accuracy and response time. Moreover, an experimental prototype is built to test and validate the proposed PV interface system.

  18. Abnormal grooming activity in Dab1(scm) (scrambler) mutant mice. (United States)

    Strazielle, C; Lefevre, A; Jacquelin, C; Lalonde, R


    Dab1(scm) mutant mice, characterized by cell ectopias and degeneration in cerebellum, hippocampus, and neocortex, were compared to non-ataxic controls for different facets of grooming caused by brief water immersions, as well as some non-grooming behaviors. Dab1(scm) mutants were strongly affected in their quantitative functional parameters, exhibiting higher starting latencies before grooming relative to non-ataxic littermates of the A/A strain, fewer grooming bouts, and grooming components of shorter duration, with an unequal regional distribution targeting almost totally the rostral part (head washing and forelimb licking) of the animal. Only bouts of a single grooming element were preserved. The cephalocaudal order of grooming elements appeared less disorganized, mutant and control mice initiating the grooming with head washing and forelimb licking prior to licking posterior parts. However, mutants differed from controls in that all their bouts were incomplete but uninterrupted, although intergroup difference for percentage of the incorrect transitions was not significant. In contrast to grooming, Dab1(scm) mice ambulated for a longer time. During walking episodes, they exhibited more body scratching than controls, possibly to compensate for the lack of licking different body parts. In conjunction with studies with other ataxic mice, these results indicate that the cerebellar cortex affects grooming activity and is consequently involved in executing various components, but not in its sequential organization, which requires other brain regions such as cerebral cortices or basal ganglia.

  19. Dabbing the Skin Surface Dry During Ice Massage Augments Rate of Temperature Drop. (United States)

    Sidhu, Amrik; Lentell, Gary; Pettitt, Robert W

    While ice massage (IM) is a rapid cooling technique used to facilitate therapeutic movements in the rehabilitation process, evidence of its efficacy over alternative therapeutic protocols is scarce. We determined whether dabbing the skin surface dry during a standard IM treatment would lead to greater rate of skin temperature reduction in comparison to without dabbing; and whether dabbing the skin would lead to an acute change in flexibility. Sixteen healthy volunteers received a "dabbing" and "non-dabbing" 7-minute IM treatment over the surface of each triceps surae muscle. Minute-by-minute temperature change in skin surface was evaluated using an infrared thermometer. Active (AROM) and passive (PROM) range of motion were evaluated via hand-held goniometer and passive stretch force was evaluated with an algometer. Dependent variables (reported as Mean ± SD) were tested with two-way analysis of variance with repeated measures. Skin temperature (°C) was reduced to with dabbing (5.8 ± 1.1) in comparison to without dabbing (6.8 ± 1.4), evoking significantly greater cooling at 1-min of ice massage (group X time interaction, p0.05) for either IM group. The dabbing protocol resulted in more rapid rate of temperature drop at 1-minute, however, both IM techniques are sufficient in cooling surface temperature after 2-minutes of IM. Further study is warranted to determine the clinical significance of the dabbing procedure.

  20. Technical Aspects of DAB and IBOC Terrestrial Digital Radio Broadcasting Standards

    Directory of Open Access Journals (Sweden)

    Moumtadi F.


    Full Text Available The development of digital radiobroadcast standards and the advantages related to it (optimization of video, audio and applications transmission and services makes indispensable the study of its technical characteristics, due to the definition, over common parameters, of the advantages of each standard by itself and in comparison to others. In this paper the basic technical characteristics of two terrestrial digital radiobroadcasting standards are shown: on one hand, the so called “In-Band-On-Channel” (IBOC and, on the other, the “Digital Audio Broadcast” (DAB standard. The analysis compares the data management procedures of the standards and its relation with the open systems interconnection model – OSI, that opens the possibility to make a real comparison between them. At the end it is concluded that, technologically, the possibility for radio stations to use their actual infrastructure without capital modifications and / or enhancements, makes IBOC a clear option of implementation for digital radiobroadcasting in countries like Mexico.

  1. Dab2IP GTPase activating protein regulates dendrite development and synapse number in cerebellum.

    Directory of Open Access Journals (Sweden)

    Shuhong Qiao

    Full Text Available DOC-2/DAB-2 interacting protein (Dab2IP is a GTPase activating protein that binds to Disabled-1, a cytosolic adapter protein involved in Reelin signaling and brain development. Dab2IP regulates PI3K-AKT signaling and is associated with metastatic prostate cancer, abdominal aortic aneurysms and coronary heart disease. To date, the physiological function of Dab2IP in the nervous system, where it is highly expressed, is relatively unknown. In this study, we generated a mouse model with a targeted disruption of Dab2IP using a retrovirus gene trap strategy. Unlike reeler mice, Dab2IP knock-down mice did not exhibit severe ataxia or cerebellar hypoplasia. However, Dab2IP deficiency produced a number of cerebellar abnormalities such as a delay in the development of Purkinje cell (PC dendrites, a decrease in the parallel fiber synaptic marker VGluT1, and an increase in the climbing fiber synaptic marker VGluT2. These findings demonstrate for the first time that Dab2IP plays an important role in dendrite development and regulates the number of synapses in the cerebellum.

  2. Cutting edge: Dab2 is a FOXP3 target gene required for regulatory T cell function. (United States)

    Jain, Nitya; Nguyen, Hai; Friedline, Randall H; Malhotra, Nidhi; Brehm, Michael; Koyanagi, Madoka; Bix, Mark; Cooper, Jonathan A; Chambers, Cynthia A; Kang, Joonsoo


    FOXP3-expressing regulatory T (Treg) cells are vital for maintaining peripheral T cell tolerance and homeostasis. The mechanisms by which FOXP3 target genes orchestrate context-dependent Treg cell function are largely unknown. In this study we show that in mouse peripheral lymphocytes the Drosophila Disabled-2 (Dab2) homolog, a gene that is involved in enhancing TGFbeta responses, is exclusively expressed in FOXP3+ regulatory T cells. Dab2 is a direct target of FOXP3, and regulatory T cells lacking DAB2 are functionally impaired in vitro and in vivo. However, not all aspects of Treg cell function are perturbed, and DAB2 appears to be dispensable for Treg cell function in maintaining naive T cell homeostasis.

  3. Neurobehavioral performances and brain regional metabolism in Dab1(scm) (scrambler) mutant mice. (United States)

    Jacquelin, C; Lalonde, R; Jantzen-Ossola, C; Strazielle, C


    As disabled-1 (DAB1) protein acts downstream in the reelin signaling pathway modulating neuronal migration, glutamate neurotransmission, and cytoskeletal function, the disabled-1 gene mutation (scrambler or Dab1(scm) mutation) results in ataxic mice displaying dramatic neuroanatomical defects similar to those observed in the reeler gene (Reln) mutation. By comparison to non-ataxic controls, Dab1(scm) mutants showed severe motor coordination impairments on stationary beam, coat-hanger, and rotorod tests but were more active in the open-field. Dab1(scm) mutants were also less anxious in the elevated plus-maze but with higher latencies in the emergence test. In mutants versus controls, changes in regional brain metabolism as measured by cytochrome oxidase (COX) activity occurred mainly in structures intimately connected with the cerebellum, in basal ganglia, in limbic regions, particularly hippocampus, as well as in visual and parietal sensory cortices. Although behavioral results characterized a major cerebellar disorder in the Dab1(scm) mutants, motor activity impairments in the open-field were associated with COX activity changes in efferent basal ganglia structures such as the substantia nigra, pars reticulata. Metabolic changes in this structure were also associated with the anxiety changes observed in the elevated plus-maze and emergence test. These results indicate a crucial participation of the basal ganglia in the functional phenotype of ataxic Dab1(scm) mutants. Copyright © 2013 Elsevier B.V. All rights reserved.

    Min, Jiang; Liu, Liang; Li, Xiaolan; Jiang, Jianwu; Wang, Jingtao; Zhang, Bo; Cao, Dengyi; Yu, Dongdong; Tao, Deding; Hu, Junbo; Gong, Jianping; Xie, Daxing


    Metastasis is a critical factor for the high mortality of colorectal cancer (CRC), but its mechanism is not completely understood. Epithelial-mesenchymal transition (EMT) is thought to play a key role in metastasis and also increases the cancer stem cell (CSC) feature that facilitates metastatic colonization. In this study, we investigated the biological roles of DAB2IP regulating EMT and stem cell-like features in human CRC. We demonstrate that DAB2IP suppresses NF-κB-mediated EMT and CSC features in CRC cells. In DAB2IP knockout mice, we discovered the hyperplasia in colonic epithelium which aberrantly represents the mesenchymal feature and NF-κB pathway activation. In clinic CRC tissue, we also reveal that reduced DAB2IP can enrich the CD133(+) subpopulation. DAB2IP expression was inversely correlated with tumor differentiation and metastasis, and patients with lower DAB2IP expression had shorter overall survival time. Taken together, our study demonstrates that DAB2IP inhibits NF-κB-inducing EMT and CSC to suppress the CRC progression, and also suggests that DAB2IP is a beneficial prediction factor for CRC patient prognosis.

  9. "Time for dabs": Analyzing Twitter data on marijuana concentrates across the U.S. (United States)

    Daniulaityte, Raminta; Nahhas, Ramzi W; Wijeratne, Sanjaya; Carlson, Robert G; Lamy, Francois R; Martins, Silvia S; Boyer, Edward W; Smith, G Alan; Sheth, Amit


    Media reports suggest increasing popularity of marijuana concentrates ("dabs"; "earwax"; "budder"; "shatter; "butane hash oil") that are typically vaporized and inhaled via a bong, vaporizer or electronic cigarette. However, data on the epidemiology of marijuana concentrate use remain limited. This study aims to explore Twitter data on marijuana concentrate use in the U.S. and identify differences across regions of the country with varying cannabis legalization policies. Tweets were collected between October 20 and December 20, 2014, using Twitter's streaming API. Twitter data filtering framework was available through the eDrugTrends platform. Raw and adjusted percentages of dabs-related tweets per state were calculated. A permutation test was used to examine differences in the adjusted percentages of dabs-related tweets among U.S. states with different cannabis legalization policies. eDrugTrends collected a total of 125,255 tweets. Almost 22% (n=27,018) of these tweets contained identifiable state-level geolocation information. Dabs-related tweet volume for each state was adjusted using a general sample of tweets to account for different levels of overall tweeting activity for each state. Adjusted percentages of dabs-related tweets were highest in states that allowed recreational and/or medicinal cannabis use and lowest in states that have not passed medical cannabis use laws. The differences were statistically significant. Twitter data suggest greater popularity of dabs in the states that legalized recreational and/or medical use of cannabis. The study provides new information on the epidemiology of marijuana concentrate use and contributes to the emerging field of social media analysis for drug abuse research.

  10. International Space Station (ISS) Carbon Dioxide Removal Assembly (CDRA) Desiccant/Adsorbent Bed (DAB) Orbital Replacement Unit (ORU) Redesign (United States)

    Reysa, Richard P.; Lumpkin, John P.; Sherif, Dian El; Kay, Robert; Williams, David E.


    The Carbon Dioxide Removal Assembly (CDRA) is a part of the International Space Station (ISS) Environmental Control and Life Support (ECLS) system. The CDRA provides carbon dioxide (CO2) removal from the ISS on-orbit modules. Currently, the CDRA is the secondary removal system on the ISS, with the primary system being the Russian Vozdukh. Within the CDRA are two desiccant/adsorbent beds (DAB), which perform the carbon dioxide removal function. The DAB adsorbent containment approach required improvements with respect to adsorbent containment. These improvements were implemented through a redesign program and have been implemented on units returning from orbit. This paper presents a DAB design modification implementation description, a hardware performance comparison between the unmodified and modified DAB configurations, and a description of the modified DAB hardware implementation into the on-orbit CDRA.

Gillnetters participating in the coastal summer fishery for plaice follow the theoretical optimal soak tactic. The commercially used 12 h deployment during day maximises the catch....... Different soak tactics were compared to estimate the role that the choice of a soak tactic plays in the catch efficiency of both target and unwanted species. In the Danish summer gillnet fishery targeting plaice (Pleuronectes platessa), nets are deployed approximately 12 h (h) during day. Unwanted species...... are common dab (Limanda limanda) and edible crab (Cancer pagurus). The commercially used 12 h deployment during day was compared to 12 h deployment during night and 24 h deployment. On average, there were about 1.5 more catches of commercial size plaice (above 27 cm), and 2 and 4 times less catches...

  12. Otolith oxygen isotopes measured by high-precision secondary ion mass spectrometry reflect life history of a yellowfin sole (Limanda aspera). (United States)

    Matta, Mary Elizabeth; Orland, Ian J; Ushikubo, Takayuki; Helser, Thomas E; Black, Bryan A; Valley, John W


    The oxygen isotope ratio (δ(18)O value) of aragonite fish otoliths is dependent on the temperature and the δ(18)O value of the ambient water and can thus reflect the environmental history of a fish. Secondary ion mass spectrometry (SIMS) offers a spatial-resolution advantage over conventional acid-digestion techniques for stable isotope analysis of otoliths, especially given their compact nature. High-precision otolith δ(18)O analysis was conducted with an IMS-1280 ion microprobe to investigate the life history of a yellowfin sole (Limanda aspera), a Bering Sea species known to migrate ontogenetically. The otolith was cut transversely through its core and one half was roasted to eliminate organic contaminants. Values of δ(18)O were measured in 10-µm spots along three transects (two in the roasted half, one in the unroasted half) from the core toward the edge. Otolith annual growth zones were dated using the dendrochronology technique of crossdating. Measured values of δ(18)O ranged from 29.0 to 34.1‰ (relative to Vienna Standard Mean Ocean Water). Ontogenetic migration from shallow to deeper waters was reflected in generally increasing δ(18)O values from age-0 to approximately age-7 and subsequent stabilization after the expected onset of maturity at age-7. Cyclical variations of δ(18)O values within juvenile otolith growth zones, up to 3.9‰ in magnitude, were caused by a combination of seasonal changes in the temperature and the δ(18)O value of the ambient water. The ion microprobe produced a high-precision and high-resolution record of the relative environmental conditions experienced by a yellowfin sole that was consistent with population-level studies of ontogeny. Furthermore, this study represents the first time that crossdating has been used to ensure the dating accuracy of δ(18)O measurements in otoliths. Copyright © 2013 John Wiley & Sons, Ltd.

  14. Neuroprotective effect of melatonin on soluble Aβ1-42-induced cortical neurodegeneration via Reelin-Dab1 signaling pathway. (United States)

    Hu, Chunli; Wang, Pan; Zhang, Shuman; Ren, Lili; Lv, Yiheng; Yin, Rui; Bi, Jing


    Soluble Aβ 1-42 oligomers play a vital role in the development and pathogenesis of Alzheimer's disease (AD). Melatonin could delay the progress of AD through multiple mechanisms. Reelin-Dab1 signaling plays an important role in AD, including neuronal function and synaptic plasticity. However, whether melatonin could exert its neuroprotective function against soluble Aβ 1-42 -induced neurotoxicity during AD development through regulating Reelin-Dab1 signaling remains poorly understood. AD rat model was established by soluble Aβ 1-42 repeated intracerebroventricular injection. Using immunohistochemistry and Western blot analyses, the effect of melatonin on synaptic plasticity, neuritic degeneration, and astrocyte activation was investigated in cerebral cortex. Meanwhile, the expression of Reelin and Dab1 was also examined in cerebral cortex. In our in vitro study, Reelin-Dab1 signaling was inhibited by Reelin antibody, and neuroprotective effect of melatonin against Aβ 1-42 was further determined. Melatonin ameliorated the neurotoxiciy and astrocyte activation induced by Aβ 1-42 in the cerebral cortex. Melatonin also blocked the reduction in Reelin and Dab1 expression induced by Aβ 1-42 . Using in vitro study, Reelin inactivation completely abolished the protective effect of melatonin against Aβ 1-42 -induced neurotoxicity. Melatonin might play its neuroprotective role against Aβ 1-42 through mediating Reelin-Dab1 signaling pathway. Melatonin could be a safe and remarkable therapeutic candidate for AD and other aged-associated neurodegenerative diseases.

  15. RNAi-mediated knock-down of Dab and Numb attenuate Aβ levels via γ-secretase mediated APP processing (United States)


    Amyloid-β-protein (Aβ), the key component of senile plaques in Alzheimer's disease (AD) brain, is produced from amyloid precursor protein (APP) by cleavage of β-secretase and then γ-secretase. APP adaptor proteins with phosphotyrosine-binding (PTB) domains, including Dab (gene: DAB) and Numb (gene: NUMB), can bind to and interact with the conserved YENPTY-motif in the APP C-terminus. Here we describe, for the first time, the effects of RNAi knock-down of Dab and Numb expression on APP processing and Aβ production. RNAi knock-down of Dab and Numb in H4 human neuroglioma cells stably transfected to express either FL-APP (H4-FL-APP cells) or APP-C99 (H4-APP-C99 cells) increased levels of APP-C-terminal fragments (APP-CTFs) and lowered Aβ levels in both cell lines by inhibiting γ-secretase cleavage of APP. Finally, RNAi knock-down of APP also reduced levels of Numb in H4-APP cells. These findings suggest that pharmacologically blocking interaction of APP with Dab and Numb may provide novel therapeutic strategies of AD. The notion of attenuating γ-secretase cleavage of APP via the APP adaptor proteins, Dab and Numb, is particularly attractive with regard to therapeutic potential, given that side effects of γ-secretase inhibition owing to impaired proteolysis of other γ-secretase substrates, e.g. Notch, might be avoided.

  16. Introduction of Bootstrap Current Reduction in the Stellarator Optimization Using the Algorithm DAB

    International Nuclear Information System (INIS)

    Castejón, F.; Gómez-Iglesias, A.; Velasco, J. L.


    This work is devoted to introduce new optimization criterion in the DAB (Distributed Asynchronous Bees) code. With this new criterion, we have now in DAB the equilibrium and Mercier stability criteria, the minimization of Bxgrad(B) criterion, which ensures the reduction of neoclassical transport and the improvement of the confinement of fast particles, and the reduction of bootstrap current. We have started from a neoclassically optimised configuration of the helias type and imposed the reduction of bootstrap current. The obtained configuration only presents a modest reduction of total bootstrap current, but the local current density is reduced along the minor radii. Further investigations are developed to understand the reason of this modest improvement.

    The reelin and dab1 genes are necessary for appropriate neuronal migration and lamination during brain development. Since these processes are controlled by thyroid hormone, we studied the effect of thyroid hormone deprivation and administration on the expression of reelin anddab1. As shown by Northern analysis, in situ hybridization, and immunohistochemistry studies, hypothyroid rats expressed decreased levels of reelinRNA and protein during the perinatal period [embryonic day 18 (E18) and po...

    Jacquelin, C; Strazielle, C; Lalonde, R


    Homozygous Dab1(scm) mouse mutants with cell ectopias in cerebellar cortex, hippocampus, and neocortex were compared to non-ataxic controls on the SHIRPA primary screening battery on postnatal days 8, 15, and 22, as well as in the adult period. Dab1(scm) mutants were distinguished from non-ataxic controls as early as postnatal day 8 based on body tremor, gait anomalies, and body weight. On postnatal day 15, motor coordination deficits were evident on horizontal bar and inclined or vertical grid tests in association with a weaker grip strength. Likewise, mutants were distinguished from controls on drop righting and hindpaw clasping tests. Further differences were detected on postnatal day 22 in the form of fewer visual placing, touch escape, trunk curl, freezing, and vocalization responses, as well as squares traversed in the open-field. Evaluation at the adult age demonstrated similar impairments, indicative of permanent motor alterations. Neuronal metabolic activity was estimated by cytochrome oxidase histochemistry on cerebellar sections. Cerebellar cortical layers and efferent deep nuclei of Dab1(scm) mice appeared hypometabolic relative to non-ataxic mice despite normal metabolism in both regular and ectopic Purkinje cells.

  19. miR-367 regulation of DOC-2/DAB2 interactive protein promotes proliferation, migration and invasion of osteosarcoma cells. (United States)

    Cai, Wei; Jiang, Haitao; Yu, Yifan; Xu, Yong; Zuo, Wenshan; Wang, Shouguo; Su, Zhen


    Recently, miR-367 is reported to exert either oncogenic or tumor suppressive effects in human malignancies. Recent study reports that miR-367 is up-regulated in OS tissues and cell lines, and abrogates adriamycin-induced apoptosis. The clinical significance of miR-367 and its function in OS need further investigation. In our study, miR-367 expression in OS was markedly elevated compared with corresponding non-tumor tissues. High miR-367 expression was associated with malignant clinical features and poor prognosis of OS patients. In accordance, the levels of miR-367 were dramatically up-regulated in OS cells. Loss of miR-367 expression in Saos-2 cells obviously inhibited the proliferation, migration and invasion of cancer cells in vitro. Meanwhile, miR-367 restoration promoted these malignant behaviors of MG-63 cells. Mechanistically, miR-367 negatively regulated DOC-2/DAB2 interactive protein (DAB2IP) abundance in OS cells. Hereby, DAB2IP was recognized as a direct target gene of miR-367 in OS. DAB2IP mRNA level was down-regulated and inversely correlated with miR-367 expression in OS specimens. DAB2IP overexpression prohibited proliferation, migration and invasion in Saos-2 cells, while DAB2IP knockdown showed promoting effects on proliferation, migration and invasion of MG-63 cells. Furthermore, the role of miR-367 might be mediated by DAB2IP-regulated phosphorylation of ERK and AKT in OS cells. To conclude, miR-367 may function as a biomarker for prediction of prognosis and a target for OS therapy. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

  20. Identification of 48 full-length MHC-DAB functional alleles in miiuy croaker and evidence for positive selection. (United States)

    Liu, Jiang; Sun, Yueyan; Xu, Tianjun


    Major histocompatibility complex (MHC) molecules play a vital role in the immune response and are a highly polymorphic gene superfamily in vertebrates. As the molecular marker associated with polymorphism and disease susceptibility/resistance, the polymorphism of MHC genes has been investigated in many tetrapods and teleosts. Most studies were focused on the polymorphism of the second exon, which encodes the peptide-binding region (PBR) in the α1- or β1-domain, but few studies have examined the full-length coding region. To comprehensive investigate the polymorphism of MHC gene, we identified 48 full-length miiuy croaker (Miichthys miiuy) MHC class IIB (Mimi-DAB) functional alleles from 26 miiuy croaker individuals. All of the alleles encode 34 amino acid sequences, and a high level of polymorphism was detected in Mimi-DAB alleles. The rate of non-synonymous substitutions (dN) occurred at a significantly higher frequency than that of synonymous substitutions (dS) in the PBR, and this result suggests that balancing selection maintains polymorphisms at the Mimi-DAB locus. Phylogenetic analysis based on the full-length and exon 2 sequences of Mimi-DAB alleles both showed that the Mimi-DAB alleles were clustered into two major groups. A total of 19 positive selected sites were identified on the Mimi-DAB alleles after testing for positive selection, and 14 sites were predicted to be associated with antigen-binding sites, which suggests that most of selected sites are significant for disease resistance. The polymorphism of Mimi-DAB alleles provides an important resource for analyzing the association between the polymorphism of MHC gene and disease susceptibility/resistance, and for researching the molecular selective breeding of miiuy croaker with enhanced disease resistance.

  1. A little "dab" will do ya' in: a case report of neuro-and cardiotoxicity following use of cannabis concentrates. (United States)

    Rickner, Shannon S; Cao, Dazhe; Kleinschmidt, Kurt; Fleming, Steven


    The use of marijuana and cannabis concentrates is increasing, especially following decriminalization in several states. Psychosis and cardiotoxicity have been reported following cannabis use; however, myocardial injury from "dabbing" has not yet been reported. We report a case of hyperthermia, tachycardia, hypertension, severe agitation, neuro-, and cardiotoxicity following the use of "dabs" where there is concomitant confirmatory biological and sample testing. A 17-year-old athletic man developed agitation requiring sedation and intubation for safety, with peak systolic blood pressures in the 190s and hyperthermia (to 102 °F). He developed elevated serum troponins with persistent tachycardia despite sedation and no clear non-intoxicant etiology. It was discovered that the patient had recently been "dabbing"; an exhaustive search of his home found a sample of the "dabs" which was analyzed along with a comprehensive urine drug screen by tandem liquid mass spectroscopy (t-LCMS) for confirmation. Tetrahydrocannabinol (THC) has been increasingly associated with agitation and cardiotoxicity, while cannabidiol (CBD) has been associated with neuroprotective, inhibitory states. We propose that increasing concentrations of THC as well as THC:CBD ratios seen in cannabis concentrates such as "dabs" may cause agitation and end-organ damage through sympathomimetic and serotonergic pathways.

    The dendrimer hexadecamine poly(propylene)imine (DAB-Am-16) of third generation (G-3) was anchored on the silica gel surface. The modified silica interact easily with Cu 2+ and then with hexacyanoferrate to form copper hexacyanoferrate. The modified silica was characterized by following techniques: nuclear magnetic resonance (NMR), infrared (FTIR), energy dispersive X-ray (EDX) and cyclic voltammetry. As application of the composite obtained, the modified silica containing copper hexacyanoferrate (CuHCFSD) was tested for a voltammetric determination of nitrite using a graphite paste modified electrode. The modified graphite paste electrode can be applied also to the determination of others biological substances with success. (author)

  5. RBX2 maintains final retinal cell position in a DAB1-dependent and -independent fashion. (United States)

    Fairchild, Corinne L; Hino, Keiko; Han, Jisoo S; Miltner, Adam M; Peinado Allina, Gabriel; Brown, Caileigh E; Burns, Marie E; La Torre, Anna; Simó, Sergi


    The laminated structure of the retina is fundamental for the organization of the synaptic circuitry that translates light input into patterns of action potentials. However, the molecular mechanisms underlying cell migration and layering of the retina are poorly understood. Here, we show that RBX2, a core component of the E3 ubiquitin ligase CRL5, is essential for retinal layering and function. RBX2 regulates the final cell position of rod bipolar cells, cone photoreceptors and Muller glia. Our data indicate that sustained RELN/DAB1 signaling, triggered by depletion of RBX2 or SOCS7 - a CRL5 substrate adaptor known to recruit DAB1 - causes rod bipolar cell misposition. Moreover, whereas SOCS7 also controls Muller glia cell lamination, it is not responsible for cone photoreceptor positioning, suggesting that RBX2, most likely through CRL5 activity, controls other signaling pathways required for proper cone localization. Furthermore, RBX2 depletion reduces the number of ribbon synapses and disrupts cone photoreceptor function. Together, these results uncover RBX2 as a crucial molecular regulator of retina morphogenesis and cone photoreceptor function. © 2018. Published by The Company of Biologists Ltd.

  6. Multitarget tracking in cluttered environment for a multistatic passive radar system under the DAB/DVB network (United States)

    Shi, Yi Fang; Park, Seung Hyo; Song, Taek Lyul


    The target tracking using multistatic passive radar in a digital audio/video broadcast (DAB/DVB) network with illuminators of opportunity faces two main challenges: the first challenge is that one has to solve the measurement-to-illuminator association ambiguity in addition to the conventional association ambiguity between the measurements and targets, which introduces a significantly complex three-dimensional (3-D) data association problem among the target-measurement illuminator, this is because all the illuminators transmit the same carrier frequency signals and signals transmitted by different illuminators but reflected via the same target become indistinguishable; the other challenge is that only the bistatic range and range-rate measurements are available while the angle information is unavailable or of very poor quality. In this paper, the authors propose a new target tracking algorithm directly in three-dimensional (3-D) Cartesian coordinates with the capability of track management using the probability of target existence as a track quality measure. The proposed algorithm is termed sequential processing-joint integrated probabilistic data association (SP-JIPDA), which applies the modified sequential processing technique to resolve the additional association ambiguity between measurements and illuminators. The SP-JIPDA algorithm sequentially operates the JIPDA tracker to update each track for each illuminator with all the measurements in the common measurement set at each time. For reasons of fair comparison, the existing modified joint probabilistic data association (MJPDA) algorithm that addresses the 3-D data association problem via "supertargets" using gate grouping and provides tracks directly in 3-D Cartesian coordinates, is enhanced by incorporating the probability of target existence as an effective track quality measure for track management. Both algorithms deal with nonlinear observations using the extended Kalman filtering. A simulation study is

  7. Selection, diversity and evolutionary patterns of the MHC class II DAB in free-ranging Neotropical marsupials

    Directory of Open Access Journals (Sweden)

    Otten Celine


    Full Text Available Abstract Background Research on the genetic architecture and diversity of the MHC has focused mainly on eutherian mammals, birds and fish. So far, studies on model marsupials used in laboratory investigations indicated very little or even no variation in MHC class II genes. However, natural levels of diversity and selection are unknown in marsupials as studies on wild populations are virtually absent. We used two endemic South American mouse opossums, Gracilinanus microtarsus and Marmosops incanus, to investigate characteristic features of MHC selection. This study is the first investigation of MHC selection in free-ranging Neotropical marsupials. In addition, the evolutionary history of MHC lineages within the group of marsupials was examined. Results G. microtarsus showed extensive levels of MHC diversity within and among individuals as 47 MHC-DAB alleles and high levels of sequence divergence were detected at a minimum of four loci. Positively selected codon sites were identified, of which most were congruent with human antigen binding sites. The diversity in M. incanus was rather low with only eight observed alleles at presumably two loci. However, these alleles also revealed high sequence divergence. Again, positive selection was identified on specific codon sites, all congruent with human ABS and with positively selected sites observed in G. microtarsus. In a phylogenetic comparison alleles of M. incanus interspersed widely within alleles of G. microtarsus with four alleles being present in both species. Conclusion Our investigations revealed extensive MHC class II polymorphism in a natural marsupial population, contrary to previous assumptions. Furthermore, our study confirms for the first time in marsupials the presence of three characteristic features common at MHC loci of eutherian mammals, birds and fish: large allelic sequence divergence, positive selection on specific sites and trans-specific polymorphism.

  9. Nonlinear time series analysis of food intake in the dab and the rainbow trout. (United States)

    King, J W; Ruohonen, K; Grove, D J; Hammerstein, A


    Evidence suggests that dab and rainbow trout are able to quickly adjust their food intake to an appropriate level when offered novel diets. In addition day-to-day and meal-to-meal food intake varies greatly and meal timing is plastic. Why this is the case is not clear: Food intake in fish is influenced by many factors, however the hierarchy and mechanisms by which these interact is not yet fully understood. A model of food intake may be helpful to understand these phenomena; to determine model type it is necessary to understand the qualitative nature of food intake. Food intake can be regarded as an autoregressive (AR) time series, as the amount of food eaten at time t will be influenced by previous meals, and this allows food intake to be considered using time series analyses. Here, time series data were analysed using nonlinear techniques to obtain qualitative information from which evidence for the hierarchy of mechanisms controlling food intake may be drawn. Time series were obtained for a group of dab and individuals and a group of rainbow trout for analysis. Surrogate data sets were generated to test several null hypotheses describing linear processes and all proved significantly different to the real data, suggesting nonlinear dynamics. Examination of topography and recurrence diagrams suggested that all series were deterministic and non-stationary. The point correlation dimension (PD2i) suggested low-dimensional dynamics. Our findings suggest therefore that any model of appetite should create output that is deterministic, non-stationary, low-dimensional and having nonlinear dynamics.

  10. A high linearity current mode second IF CMOS mixer for a DRM/DAB receiver (United States)

    Jian, Xu; Zheng, Zhou; Yiqiang, Wu; Zhigong, Wang; Jianping, Chen


    A passive current switch mixer was designed for the second IF down-conversion in a DRM/DAB receiver. The circuit consists of an input transconductance stage, a passive current switching stage, and a current amplifier stage. The input transconductance stage employs a self-biasing current reusing technique, with a resistor shunt feedback to increase the gain and output impedance. A dynamic bias technique is used in the switching stage to ensure the stability of the overdrive voltage versus the PVT variations. A current shunt feedback is introduced to the conventional low-voltage second-generation fully balanced multi-output current converter (FBMOCCII), which provides very low input impedance and high output impedance. With the circuit working in current mode, the linearity is effectively improved with low supply voltages. Especially, the transimpedance stage can be removed, which simplifies the design considerably. The design is verified with a SMIC 0.18 μm RF CMOS process. The measurement results show that the voltage conversation gain is 1.407 dB, the NF is 16.22 dB, and the IIP3 is 4.5 dBm, respectively. The current consumption is 9.30 mA with a supply voltage of 1.8 V. This exhibits a good compromise among the gain, noise, and linearity for the second IF mixer in DRM/DAB receivers.

  11. Developmental defects in pelagic embryos of several flatfish species in the Southern North sea (United States)

    Cameron, P.; Berg, J.; Dethlefsen, V.; Von Westernhagen, H.

    In the spring of 1984 through and in the summer of 1987 pelagic flatfish eggs were collected in horizontal subsurface hauls with a 1-m ring net in the southern North Sea between 51°49' to 55°30'N and 2°30' to 8°00'E. The flatfish eggs were observed alive for their developmental stage and aberrations from normal development. Flatfish eggs occurring in the winter ichthyoplankton of the southern North Sea were dab, Limanda limanda; flounder. Platichthys flesus; plaice, Pleuronectes platessa, and long rough dab, Hippoglossoides platessoides. Summer samples contained dab, turbot, Psetta maxima; little sole, Buglossidium luteum; common sole, Solea solea; Norwegian topknot, Phrynorhombus norwegicus, and lemon sole, Microstomus kitt. In winter as well as in summer eggs of dab were the most abundant in the southern North Sea with up to 249 eggs·m -3 surface water in winter and 26 eggs·m -3 in summer. The investigations revealed considerable quantities of abnormally developed flatfish embryos in the plankton samples. Highest malformation rates were recorded for the early stages of dab (44.4%) followed by flounder (41.3%) and plaice (26.0%) in winter; in summer these rates were for dab 18.9%, for turbot 14.1% and for little sole 12.5%. Generally malformation rates decreased with development. Areas of high malformation rates were off the river estuaries and in near-shore areas along the Dutch and German coasts. Malformation rates decreased with the distance from the coast. Causes and effects of the occurrence of malformations during embryonic development are discussed.

    Purpose: This pilot study investigates the role of DOC-2/DAB2 Interacting Protein (DAB2IP) and enhancer of zeste homolog 2 (EZH2) as prognostic biomarkers in high-risk prostate cancer patients receiving definitive radiation therapy. Methods and Materials: Immunohistochemistry was performed and scored by an expert genitourinary pathologist. Clinical endpoints evaluated were freedom from biochemical failure (FFBF), castration resistance–free survival (CRFS), and distant metastasis–free survival (DMFS). Log-rank test and Cox regression were used to determine significance of biomarker levels with clinical outcome. Results: Fifty-four patients with high-risk prostate cancer (stage ≥T3a, or Gleason score ≥8, or prostate-specific antigen level ≥20 ng/mL) treated with radiation therapy from 2005 to 2012 at our institution were evaluated. Nearly all patients expressed EZH2 (98%), whereas 28% of patients revealed DAB2IP reduction and 72% retained DAB2IP. Median follow-up was 34.0 months for DAB2IP-reduced patients, 29.9 months for DAB2IP-retained patients, and 32.6 months in the EZH2 study. Reduction in DAB2IP portended worse outcome compared with DAB2IP-retained patients, including FFBF (4-year: 37% vs 89%, P=.04), CRFS (4-year: 50% vs 90%, P=.02), and DMFS (4-year: 36% vs 97%, P=.05). Stratified EZH2 expression trended toward significance for worse FFBF and CRFS (P=.07). Patients with reduced DAB2IP or highest-intensity EZH2 expression exhibited worse FFBF (4-year: 32% vs 95%, P=.02), CRFS (4-year: 28% vs 100%, P<.01), and DMFS (4-year: 39% vs 100%, P=.04) compared with the control group. Conclusion: Loss of DAB2IP is a potent biomarker that portends worse outcome despite definitive radiation therapy for patients with high-risk prostate cancer. Enhancer of zeste homolog 2 is expressed in most high-risk tumors and is a less potent discriminator of outcome in this study. The DAB2IP status in combination with degree of EZH2 expression may be useful for

  14. The Hmong 'Dab Pog Couple' Story and its Significance in Arriving at an Understanding of Hmong Ritual

    Full Text Available Many Hmong continue to believe in the efficacy, and commission the practice by shamans of, some of the more important traditional rituals, such as marriage rites (kab tshoob kev kos, "soul calling" (hu plig, healing rites (ua neeb or khaw koob, worshipping the "house spirit" (teev xwm kab, and funeral rites (kev ploj tuag. Certainly, however, there are those Hmong, especially among younger generations, who either choose not to participate in such rituals, or who participate in them without any clear comprehension of the deeper meaning or details; indeed, without any strongly held beliefs regarding the cosmological system which is the ritual's foundation, underpinning and supporting the call for the many actions, gestures, offerings and recitations which, in the final analysis, constitute the bulk of any such performance. This philosophical ambivalence on the part of modern celebrants renders the position of ritual in Hmong society somewhat problematic. In addition, the various Hmong clans have, in the past, of necessity resided in divergent geographical locales, and, as a result of this and other factors, have often espoused divergent, philosophically and culturally heterogeneous, beliefs. This, taken together with the fact that Hmong customs have been orally transmitted down the generations, has had the result that there may be several versions of the meaning, and method of performance, of any given ritual.The presentation that follows will discuss the "Dab Pog Couple" story as it bears upon the origins of Hmong cultural tradition and embedded social values. Such a consideration will, at the same time, serve to introduce and elucidate many of the meanings behind, and values attached to, Hmong rituals in general and will thus provide a contribution to the understanding of these rituals and their relation to Dab Neeg (Folk Legends within the Hmong cultural studies scholarly literature.Briefly stated, the Hmong believe that the "Dab Pog" couple

  16. Hybrid graphene oxide/DAB-Am-16 dendrimer: Preparation, characterization chemical reactivity and their electrocatalytic detection of L-Dopamine (United States)

    Do Carmo, Devaney Ribeiro; Fernandes, Daniela Silvestrini


    Graphene oxide (GO) was chemically modified with a poly(propylene)imine Generation 3.0 dendrimer (DAB-Am-16). The characterization, structure and properties of hybrid graphene oxide/DAB-Am-16 dendrimer was studied by Raman spectroscopy, Fourier-Transforming Infrared Spectroscopy (FT-IR), X-Ray Photoelectron Spectroscopic (XPS), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Thermogravimetric analysis. After functionalized the hybrid material (GOD) can interact with copper and subsequently with hexacyanoferrate (III) ions (GODHCu). The GODHCu incorporated into a graphite paste electrode (20% w/w) was applied to an electrocatalytic detection of neurotransmitter L-dopamine using differential pulse voltammetry. The analytical curve showed a linear response in the concentration range from 1.0 × 10-7 to 1.0 × 10-5 mol L-1 with a corresponding equation Y(A) = 1.706 × 10-5 + 0.862 [L-dopamine] and a correlation coefficient r2 = 0.998. The detection limit was 6.36 × 10-7 mol L-1 with a relative standard deviation of ±4% (n = 3) and an amperometric sensitivity of 0.862 A/mol L-1.

  17. Albumin endocytosis via megalin in astrocytes is caveola- and Dab-1 dependent and is required for the synthesis of the neurotrophic factor oleic acid. (United States)

    Bento-Abreu, André; Velasco, Ana; Polo-Hernández, Erica; Lillo, Concepción; Kozyraki, Renata; Tabernero, Arantxa; Medina, José M


    The synthesis and release of the neurotrophic factor oleic acid requires internalization of albumin into the astrocyte, which is mediated by megalin. In this study, we show that the binding and internalization of albumin involve its interaction with megalin, caveolin-1, caveolin-2 and cavin, but not with clathrin in astrocytes from primary culture. Electron microscopy analyses revealed albumin-gold complexes localized in caveolae, but not in clathrin-coated vesicles. Neither chlorpromazine nor silencing clathrin expression modified albumin uptake. Silencing caveolin-1 strongly reduced the binding and internalization of albumin and the distribution of megalin in the plasma membrane. However, silencing caveolin-2 only decreased albumin internalization, suggesting that caveolin-1 is responsible for megalin recruitment to the caveolae and that caveolin-2 participates in caveolae internalization. In most tissues, the cytosolic adaptor protein disabled (Dab)-2 connects megalin to clathrin, astrocytes lack Dab-2; instead, they express Dab-1, which interacts with caveolin-1 and megalin and is required for albumin internalization. The transcytosis of albumin in astrocytes, including the passage through the endoplasmic reticulum, which is a compulsory step for oleic acid synthesis, was confirmed by electron microscopy analyses. Thus, whereas silencing clathrin did not modify the synthesis and release of oleic acid, the knock-down of caveolin-1, caveolin-2 and Dab-1 strongly reduced the synthesis and release of this neurotrophic factor. In conclusion, caveola-mediated endocytosis of albumin requires megalin and the adaptor protein Dab-1 in cultured astrocytes. Albumin endocytosis may be a key step in brain development because it stimulates the synthesis of oleic acid, which in turn promotes neuronal differentiation.

Transitions in the standards and test methods of Valerian root in the Deutsches Arzneibuch (DAB) and comparison between the USP, BP, EP and JP, and Oleum Valerianae (Japan Kesso oil) listed in DAB6 (1926)]. (United States)

    Yanagisawa, Kiyohisa


    Valerian has been used as a name for Japanese Valerian and European Valerian root. Valerian in the German market today was originally called Baldrian. Transitions in the standards and the test methods of Valerian root listed in the DAB were studied this time. Moreover, we compared these standards and test methods with those in the USP, BP, EP and JP. We also considered the pharmacology evaluation in Germany. At the time, the standards and test methods had content in accordance with the EP from DAB9 (1986) of the West Germany publication. It also agreed with the EP and BP of the same period. To date in the DAB, botanical features have been mainly derived from the discriminating characteristics of the Valerian root. In DAB9 (1986), standards and test methods were added to the content, enhancing it and making it more stringent. This is thought to have happened as a result of a new, academic finding showing an improvement in the pharmacology level. Valerian root has been listed continuously in the DAB. These listings suggest that Valerian root has continally been evaluated as a sedative. We think that the listing was connected with a relisting in the BP as a result of scientific communications between Britain and Germany, EC member nations, such as through EP publications. On the other hand, the oil made with Japanese Valerian was listed in a radical field in DAB6 (1926) in the past. This is a valuable result, proving that it was used and evaluated as an important herbal medicine from Japan and foreign countries at that time. The Japanese Valerian referred to is not grown in Japan today. Moreover, it is not possible that cultivation will be restarted through good quality revaluation. However, this fact introduces a valuable piece of history supporting the survival of Japanese Valerian and European Valerian root as a sedative in the future.

  20. Prophage induction and differential RecA and UmuDAb transcriptome regulation in the DNA damage responses of Acinetobacter baumannii and Acinetobacter baylyi.

    Directory of Open Access Journals (Sweden)

    Janelle M Hare

    Full Text Available The SOS response to DNA damage that induces up to 10% of the prokaryotic genome requires RecA action to relieve LexA transcriptional repression. In Acinetobacter species, which lack LexA, the error-prone polymerase accessory UmuDAb is instead required for ddrR induction after DNA damage, suggesting it might be a LexA analog. RNA-Seq experiments defined the DNA damage transcriptome (mitomycin C-induced of wild type, recA and umuDAb mutant strains of both A. baylyi ADP1 and A. baumannii ATCC 17978. Of the typical SOS response genes, few were differentially regulated in these species; many were repressed or absent. A striking 38.4% of all ADP1 genes, and 11.4% of all 17978 genes, were repressed under these conditions. In A. baylyi ADP1, 66 genes (2.0% of the genome, including a CRISPR/Cas system, were DNA damage-induced, and belonged to four regulons defined by differential use of recA and umuDAb. In A. baumannii ATCC 17978, however, induction of 99% of the 152 mitomycin C-induced genes depended on recA, and only 28 of these genes required umuDAb for their induction. 90% of the induced A. baumannii genes were clustered in three prophage regions, and bacteriophage particles were observed after mitomycin C treatment. These prophages encoded esvI, esvK1, and esvK2, ethanol-stimulated virulence genes previously identified in a Caenorhabditis elegans model, as well as error-prone polymerase alleles. The induction of all 17978 error-prone polymerase alleles, whether prophage-encoded or not, was recA dependent, but only these DNA polymerase V-related genes were de-repressed in the umuDAb mutant in the absence of DNA damage. These results suggest that both species possess a robust and complex DNA damage response involving both recA-dependent and recA-independent regulons, and further demonstrates that although umuDAb has a specialized role in repressing error-prone polymerases, additional regulators likely participate in these species' transcriptional

  1. The Diet and Behaviour Scale (DABS): Testing a new measure of food and drink consumption in a cohort of secondary school children from the south west of England


    Richards, Gareth; Malthouse, Alice; Smith, Andrew Paul


    A multitude of instruments exist to assess dietary intake. Many, however, are time-consuming to administer, focus primarily on macronutrient composition or the effects of specific micronutrients, and do not consider the effects of foods and drinks that fail to add significant nutritional contributions (e.g. energy drinks, chewing gum). In order to address these issues the current paper introduces the Diet and Behaviour Scale (DABS). This 29-item questionnaire is used to measure both the frequ...

  2. Inhibitory properties of 1,4-dideoxy-1,4-imino-d-arabinitol (DAB) derivatives acting on glycogen metabolising enzymes. (United States)

    Díaz-Lobo, Mireia; Concia, Alda Lisa; Gómez, Livia; Clapés, Pere; Fita, Ignacio; Guinovart, Joan J; Ferrer, Joan C


    Glycogen synthase (GS) and glycogen phosphorylase (GP) are the key enzymes that control, respectively, the synthesis and degradation of glycogen, a multi-branched glucose polymer that serves as a form of energy storage in bacteria, fungi and animals. An abnormal glycogen metabolism is associated with several human diseases. Thus, GS and GP constitute adequate pharmacological targets to modulate cellular glycogen levels by means of their selective inhibition. The compound 1,4-dideoxy-1,4-imino-d-arabinitol (DAB) is a known potent inhibitor of GP. We studied the inhibitory effect of DAB, its enantiomer LAB, and 29 DAB derivatives on the activity of rat muscle glycogen phosphorylase (RMGP) and E. coli glycogen synthase (EcGS). The isoform 4 of sucrose synthase (SuSy4) from Solanum tuberosum L. was also included in the study for comparative purposes. Although these three enzymes possess highly conserved catalytic site architectures, the DAB derivatives analysed showed extremely diverse inhibitory potential. Subtle changes in the positions of crucial residues in their active sites are sufficient to discriminate among the structural differences of the tested inhibitors. For the two Leloir-type enzymes, EcGS and SuSy4, which use sugar nucleotides as donors, the inhibitory potency of the compounds analysed was synergistically enhanced by more than three orders of magnitude in the presence of ADP and UDP, respectively. Our results are consistent with a model in which these compounds bind to the subsite in the active centre of the enzymes that is normally occupied by the glucosyl residue which is transferred between donor and acceptor substrates. The ability to selectively inhibit the catalytic activity of the key enzymes of the glycogen metabolism may represent a new approach for the treatment of disorders of the glycogen metabolism.

  4. A rapid hydrolysis method and DABS-Cl derivatization for complete amino acid analysis of octreotide acetate by reversed phase HPLC. (United States)

    Akhlaghi, Yousef; Ghaffari, Solmaz; Attar, Hossein; Alamir Hoor, Amir


    Octreotide as a synthetic cyclic octapeptide is a somatostatin analog with longer half-life and more selectivity for inhibition of the growth hormone. The acetate salt of octreotide is currently used for medical treatment of somatostatin-related disorders such as endocrine and carcinoid tumors, acromegaly, and gigantism. Octreotide contains both cysteine and tryptophan residues which make the hydrolysis part of its amino acid analysis procedure very challenging. The current paper introduces a fast and additive-free method which preserves tryptophan and cysteine residues during the hydrolysis. Using only 6 M HCl, this hydrolysis process is completed in 30 min at 150 °C. This fast hydrolysis method followed by pre-column derivatization of the released amino acids with 4-N,N-dimethylaminoazobenzene-4'-sulfonyl chloride (DABS-Cl) which takes only 20 min, makes it possible to do the complete amino acid analysis of an octreotide sample in a few hours. The highly stable-colored DABS-Cl derivatives can be detected in 436 nm in a reversed phase chromatographic system, which eliminates spectral interferences to a great extent. The amino acid analysis of octreotide acetate including hydrolysis, derivatization, and reversed phase HPLC determination was validated according to International Conference of Harmonization (ICH) guidelines.

  5. LC-MS/MS determination of the isomeric neurotoxins BMAA (beta-N-methylamino-L-alanine) and DAB (2,4-diaminobutyric acid) in cyanobacteria and seeds of Cycas revoluta and Lathyrus latifolius. (United States)

    Krüger, Thomas; Mönch, Bettina; Oppenhäuser, Steven; Luckas, Bernd


    Since diverse taxa of cyanobacteria has been linked to biosynthesis of BMAA, a controversy has arisen about the detection of neurotoxic amino acids in cyanobacteria. In this context, a novel LC-MS/MS method was developed for the unambiguous determination of beta-N-methylamino-L-alanine (BMAA) and 2,4-diaminobutyric acid (DAB) in cyanobacteria and selected plant seeds. Both neurotoxic and non-proteinogenic amino acids were analyzed without derivatization considering the total concentration of the free and protein-bound form. The investigation of overall 62 cyanobacterial samples of worldwide origin by application of this method revealed the absence of BMAA, whereas seeds of Cycas revoluta contained 6.96 microg g(-1) of free BMAA. In contrast, the isomer DAB was confirmed in 16 cyanobacterial samples in concentrations of 0.07-0.83 microg g(-1),whereof one sample is distributed as nutritional supplement. In addition, seeds of Lathyrus latifolius contained 4.21 microg g(-1) of free DAB. Limits of detection were for BMAA<1.0 microg g(-1) in the cyanobacterial matrix and<0.14 microg g(-1) in angiosperm seeds. DAB exhibits higher sensitivities of <0.06 microg g(-1) in cyanobacteria and <0.008 microg g(-1) in angiosperm seeds. The highly specific analysis method with increased detection sensitivity eliminates the disadvantages of derivatization-based methods to be discussed. Copyright 2009 Elsevier Ltd.

  6. ΔF508 CFTR surface stability is regulated by DAB2 and CHIP-mediated ubiquitination in post-endocytic compartments.

    Directory of Open Access Journals (Sweden)

    Lianwu Fu

    Full Text Available The ΔF508 mutant form of the cystic fibrosis transmembrane conductance regulator (ΔF508 CFTR that is normally degraded by the ER-associated degradative pathway can be rescued to the cell surface through low-temperature (27°C culture or small molecular corrector treatment. However, it is unstable on the cell surface, and rapidly internalized and targeted to the lysosomal compartment for degradation. To understand the mechanism of this rapid turnover, we examined the role of two adaptor complexes (AP-2 and Dab2 and three E3 ubiquitin ligases (c-Cbl, CHIP, and Nedd4-2 on low-temperature rescued ΔF508 CFTR endocytosis and degradation in human airway epithelial cells. Our results demonstrate that siRNA depletion of either AP-2 or Dab2 inhibits ΔF508 CFTR endocytosis by 69% and 83%, respectively. AP-2 or Dab2 depletion also increases the rescued protein half-life of ΔF508 CFTR by ~18% and ~91%, respectively. In contrast, the depletion of each of the E3 ligases had no effect on ΔF508 CFTR endocytosis, whereas CHIP depletion significantly increased the surface half-life of ΔF508 CFTR. To determine where and when the ubiquitination occurs during ΔF508 CFTR turnover, we monitored the ubiquitination of rescued ΔF508 CFTR during the time course of CFTR endocytosis. Our results indicate that ubiquitination of the surface pool of ΔF508 CFTR begins to increase 15 min after internalization, suggesting that CFTR is ubiquitinated in a post-endocytic compartment. This post-endocytic ubiquination of ΔF508 CFTR could be blocked by either inhibiting endocytosis, by siRNA knockdown of CHIP, or by treating cells with the CFTR corrector, VX-809. Our results indicate that the post-endocytic ubiquitination of CFTR by CHIP is a critical step in the peripheral quality control of cell surface ΔF508 CFTR.

  7. Changes in occurrence and abundance of northern / southern flatfishes over a 20-year period in a coastal nursery area (Bay of Vilaine and on the eastern continental shelf of the Bay of Biscay

    Directory of Open Access Journals (Sweden)

    Yves Désaunay


    Full Text Available Several works have demonstrated trends in the distribution of fish species relative to global warming. This study investigated whether similar trends have occurred for selected flatfish species on the continental shelf of the Bay of Biscay. These species were used as indicators and changes in their populations were studied in a coastal nursery ground where flatfish juveniles are concentrated as well as on the entire shelf. Previous studies analysing changes in sea surface temperature for the continental shelf indicate that winter warming occurred in the 1980s and 1990s. Sixteen autumn cruises conducted since 1981 in the Bay of Vilaine nursery area and 11 autumn cruises since 1987 over the entire shelf provided data on a nearly annual basis for the abundance of benthic fish. The four most common flatfish species were selected and their occurrence and yearly abundance were analysed with regard to specific biogeographic ranges and climate change. Similar results were obtained for juveniles on a nursery scale and for all age groups on the entire shelf. Although sole (Solea solea showed irregular yearly variations, northern winter spawners such as plaice (Pleuronectes platessa and dab (Limanda limanda exhibited significantly high abundance during the 1980s, followed by a continuing low level and ultimately zero catches. On the other hand, the wedge sole (Dicologoglossa cuneata, a southern summer spawner, showed an increasing trend in the late 1990s.

  8. Metabolic solutions to the biosynthesis of some diaminomonocarboxylic acids in nature: Formation in cyanobacteria of the neurotoxins 3-N-methyl-2,3-diaminopropanoic acid (BMAA) and 2,4-diaminobutanoic acid (2,4-DAB). (United States)

    Nunn, Peter B; Codd, Geoffrey A


    The non-encoded diaminomonocarboxylic acids, 3-N-methyl-2,3-diaminopropanoic acid (syn: α-amino-β-methylaminopropionic acid, MeDAP; β-N-methylaminoalanine, BMAA) and 2,4-diaminobutanoic acid (2,4-DAB), are distributed widely in cyanobacterial species in free and bound forms. Both amino acids are neurotoxic in whole animal and cell-based bioassays. The biosynthetic pathway to 2,4-DAB is well documented in bacteria and in one higher plant species, but has not been confirmed in cyanobacteria. The biosynthetic pathway to BMAA is unknown. This review considers possible metabolic routes, by analogy with reactions used in other species, by which these amino acids might be biosynthesised by cyanobacteria, which are a widespread potential environmental source of these neurotoxins. Where possible, the gene expression that might be implicated in these biosyntheses is discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

  11. Inability of a fusion protein of IL-2 and diphtheria toxin (Denileukin Diftitox, DAB389IL-2, ONTAK) to eliminate regulatory T lymphocytes in patients with melanoma. (United States)

    Attia, Peter; Maker, Ajay V; Haworth, Leah R; Rogers-Freezer, Linda; Rosenberg, Steven A


    Elimination of regulatory T lymphocytes may provide a way to break self-tolerance and unleash the anti-tumor properties of circulating lymphocytes. The use of fusion proteins, which link cytotoxic molecules to receptor targets, provides one approach to this problem. This study examined the ability of a fusion protein of interleukin-2 (IL-2) and diphtheria toxin (Denileukin Diftitox, DAB389IL-2, ONTAK) to eliminate regulatory T lymphocytes based on their expression of high-affinity IL-2 receptors. Thirteen patients (12 with metastatic melanoma, 1 with metastatic renal cell carcinoma) were treated at one of the two Food and Drug Administration-approved doses of Denileukin Diftitox (seven patients at 9 microg/kg, six patients at 18 microg/kg). None of the patients experienced an objective clinical response. Foxp3 expression did not decrease significantly overall, although it did decrease minimally among patients receiving 18 microg/kg (-2.01+/-0.618 copies of Foxp3/10(3) copies of beta-actin; P=0.031). Denileukin Diftitox did not decrease the suppressive ability of CD4CD25 cells as quantified by an in vitro co-culture suppression assay. Furthermore, the increased numbers of lymphocytes in patients resulting from treatment with IL-2 were not susceptible to Denileukin Diftitox. Administration of Denileukin Diftitox does not appear to eliminate regulatory T lymphocytes or cause regression of metastatic melanoma.

    Over a three-year period, David Moore made repeated early morning visits to the chamber of the House of Commons, making photographs of unseen and overlooked areas and submitting this political environment to the scrutiny of the document. The Commons pursues archaeology of our most important debating chamber, exploring how an environment can act as a metaphor for wider societal issues. In doing so Moore creates an incisive survey of the epicentre of British politics.

  16. Layer 6 cortical neurons require Reelin-Dab1 signaling for cellular orientation, Golgi deployment, and directed neurite growth into the marginal zone. (United States)

    O'Dell, Ryan S; Ustine, Candida J M; Cameron, David A; Lawless, Sean M; Williams, Rebecca M; Zipfel, Warren R; Olson, Eric C


    The secreted ligand Reelin is believed to regulate the translocation of prospective layer 6 (L6) neocortical neurons into the preplate, a loose layer of pioneer neurons that overlies the ventricular zone. Recent studies have also suggested that Reelin controls neuronal orientation and polarized dendritic growth during this period of early cortical development. To explicitly characterize and quantify how Reelin controls this critical aspect of neurite initiation and growth we used a new ex utero explant model of early cortical development to selectively label a subset of L6 cortical neurons for complete 3-D reconstruction. The total neurite arbor sizes of neurons in Reelin-deficient (reeler mutant) and Dab1-deficient (Reelin-non-responsive scrambler mutant) cortices were quantified and unexpectedly were not different than control arbor lengths (p = 0.51). For each mutant, however, arbor organization was markedly different: mutant neurons manifested more primary processes (neurites emitted directly from the soma) than wild type, and these neurites were longer and displayed less branching. Reeler and scrambler mutant neurites extended tangentially rather than radially, and the Golgi apparatus that normally invests the apical neurite was compact in both reeler and scrambler mutants. Mutant cortices also exhibited a neurite "exclusion zone" which was relatively devoid of L6 neuron neurites and extended at least 15 μm beneath the pial surface, an area corresponding to the marginal zone (MZ) in the wild type explants. The presence of an exclusion zone was also indicated in the orientation of mutant primary neurite and neuronal somata, which failed to adopt angles within ~20˚ of the radial line to the pial surface. Injection of recombinant Reelin to reeler, but not scrambler, mutant cortices fully rescued soma orientation, Golgi organization, and dendritic projection defects within four hrs. These findings indicate Reelin promotes directional dendritic growth into

  20. Common approach to common interests

    Energy Technology Data Exchange (ETDEWEB)



    In referring to issues confronting the energy field in this region and options to be exercised in the future, I would like to mention the fundamental condition of the utmost importance. That can be summed up as follows: any subject in energy area can never be solved by one country alone, given the geographical and geopolitical characteristics intrinsically possessed by energy. So, a regional approach is needed and it is especially necessary for the main players in the region to jointly address problems common to them. Though it may be a matter to be pursued in the distant future, I am personally dreaming a 'Common Energy Market for Northeast Asia,' in which member countries' interests are adjusted so that the market can be integrated and the region can become a most economically efficient market, thus formulating an effective power to encounter the outside. It should be noted that Europe needed forty years to integrate its market as the unified common market. It is necessary for us to follow a number of steps over the period to eventually materialize our common market concept, too. Now is the time for us to take a first step to lay the foundation for our descendants to enjoy prosperity from such a common market.

  1. PAH metabolites in fish bile: From the Seine estuary to Iceland. (United States)

    Kammann, U; Akcha, F; Budzinski, H; Burgeot, T; Gubbins, M J; Lang, T; Le Menach, K; Vethaak, A D; Hylland, K


    Polycyclic aromatic hydrocarbons (PAH) are environmental contaminants that pose significant risk to health of fish. The International Workshop on Integrated Assessment of Contaminant Impacts on the North Sea (ICON) provided the framework to investigate biomarker responses as well as contaminant concentrations side by side in marine ecosystems. Concentrations of the main PAH metabolites 1-hydroxypyrene, 1-hydroxyphenanthren and 3-hydroxybenzo(a)pyrene were determined in bile by HPLC with fluorescence detection. Fish species under investigation were dab (Limanda limanda), flounder (Platichthys flesus) and haddock (Melanogrammus aeglefinus). A contamination gradient was demonstrated from the low contaminated waters of Iceland and off-shore regions of the North Sea towards higher concentrations in coastal areas. Concentrations of PAH metabolites differed primarily according to sampling region and secondarily to species. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Stenberg, Claus; Støttrup, Josianne; Deurs, Mikael van


    Long-term effects of the Horns Rev 1 offshore wind farm (OWF) on fish abundance, diversity and spatial distribution were studied. This OWF is situated on the Horns Reef sand bank in the North Sea. Surveys were conducted in September 2001, before the OWF was established in 2002, and again...... in September 2009, 7 yr post-establishment. The sampling surveys used a multi-mesh-size gillnet. The 3 most abundant species in the surveys were whiting Merlangius merlangus, dab Limanda limanda and sandeels Ammodytidae spp. Overall fish abundance increased slightly in the area where the OWF was established...... introduced by the turbines. Rocky habitat fishes were most abundant close to the turbines while whiting was most abundant away from them. Species diversity was significantly higher close to the turbines. Overall, these results indicate that the artificial reef structures were large enough to attract fish...

  7. Environmental genotoxicity and cytotoxicity in the offshore zones of the Baltic and the North Seas. (United States)

    Rybakovas, Aleksandras; Barsiene, Janina; Lang, Thomas


    Micronuclei (MN), nuclear buds (NB) and fragmented-apoptotic cells (FA) were analyzed in mature peripheral blood and immature cephalic kidney erythrocytes of flounder (Platichthys flesus), dab (Limanda limanda) and cod (Gadus morhua) from 12 offshore sites in the Baltic Sea (479 specimens) and 11 sites in the North Sea (291 specimens), which were collected during three research vessel cruises in December 2002, 2003 and in September 2004. The highest levels of environmental genotoxicity (frequencies of MN up to 0.5 per thousand, NB - up to 0.75 per thousand) and cytotoxicity (FA - up to 0.53 per thousand) were observed in flatfishes from areas close to oil and gas platforms in the North Sea and in zones related to the extensive shipping and potentially influenced by contamination from large European Rivers (Elbe, Vistula, Oder). In dab from the offshore zones of the North Sea, the levels of nuclear abnormalities were higher as compared to those in dab from the Baltic Sea. Responses in immature kidney erythrocytes were higher than in mature erythrocytes from peripheral blood. MN frequency lower than 0.05 per thousand (the Baltic Sea) and lower than 0.1 per thousand (the North Sea) could be suspected as a reference level in the peripheral blood erythrocytes of flatfish.

  8. Impact of additional small-scale survey data on the geostatistical analyses of demersal fish species in the North Sea

    Directory of Open Access Journals (Sweden)

    Vanessa Stelzenmüller


    Full Text Available Geostatistical tools have been used to study the impact of additional small scale catch data (star survey design on the spatial analysis of fish, regarding different biological groups of dab, Limanda limanda and whiting, Merlangius merlangus. A standard survey carried out in January (2001-2003 in a meso-scale area in the German Bight was modified by additional small-scale sampling in 2002 and 2003. Adopting the star survey reduced the small-scale variability for medium-sized and male dab, as indicated by lower values of the nugget effect and an increased resolution of the spatial dependency. For whiting no reduction in the small scale variability could be detected; a significant difference in the spatial structuring was only found for two different size groups of whiting. Uncertainty of mean catches of dab and whiting was reduced in 2002, while in 2003 the effect of the star survey was less pronounced due to the high local density of the nearby stations. We conclude that the star survey design can be an inexpensive and effective procedure — depending on the species studied and/or the positioning of the nearby stations — when a minimised small-scale variability and a reduction of uncertainty in mean biomass of fish are the focus of interest.

    Feldt, Liv Egholm

    At present voluntary and philanthropic organisations are experiencing significant public attention and academic discussions about their role in society. Central to the debate is on one side the question of how they contribute to “the common good”, and on the other the question of how they can avoid...... being "polluted" by the state and market logic and maintain their distinctness rooted in civil society´s values and logics. Through a historical case analysis of the Egmont Foundation from Denmark (a corporate philanthropic foundation from 1920), the paper shows how concrete gift-giving practices...... and concepts continuously over time have blurred the different sectors and “polluted” contemporary definitions of the “common good”. The analysis shows that “the common good” is not an autonomous concept owned or developed by specific spheres of society. The analysis stresses that historically, “the common...

    This report summarizes the results of a case study on the doctrine of a common tester platform, a concept of a standardized platform that can be applicable across the broad spectrum of testing requirements throughout the various stages of a weapons program, as well as across the various weapons programs. The common tester concept strives to define an affordable, next-generation design that will meet testing requirements with the flexibility to grow and expand; supporting the initial development stages of a weapons program through to the final production and surveillance stages. This report discusses a concept investing key leveraging technologies and operational concepts combined with prototype tester-development experiences and practical lessons learned gleaned from past weapons programs.

  5. 'Historicising common sense'. (United States)

    Millstone, Noah


    This essay is an expanded set of comments on the social psychology papers written for the special issue on History and Social Psychology. It considers what social psychology, and particularly the theory of social representations, might offer historians working on similar problems, and what historical methods might offer social psychology. The social history of thinking has been a major theme in twentieth and twenty-first century historical writing, represented most recently by the genre of 'cultural history'. Cultural history and the theory of social representations have common ancestors in early twentieth-century social science. Nevertheless, the two lines of research have developed in different ways and are better seen as complementary than similar. The theory of social representations usefully foregrounds issues, like social division and change over time, that cultural history relegates to the background. But for historians, the theory of social representations seems oddly fixated on comparing the thought styles associated with positivist science and 'common sense'. Using historical analysis, this essay tries to dissect the core opposition 'science : common sense' and argues for a more flexible approach to comparing modes of thought.

The new Code of Conduct is a tool that has been designed to help us keep our workplace pleasant and productive through common standards of behaviour. Its basic principle is mutual respect and common sense. This is only natural, but not trivial…  The Director-General announced it in his speech at the beginning of the year, and the Bulletin wrote about it immediately afterwards. "It" is the new Code of Conduct, the document that lists our Organization's values and describes the basic standards of behaviour that we should both adopt and expect from others.

But what it will do is provide a framework for our existing rights and obligations." The aim of a co...

  7. Common Vestibular Disorders

    Directory of Open Access Journals (Sweden)

    Dimitrios G. Balatsouras


    Full Text Available The three most common vestibular diseases, benign paroxysmal positional vertigo (BPPV, Meniere's disease (MD and vestibular neuritis (VN, are presented in this paper. BPPV, which is the most common peripheral vestibular disorder, can be defined as transient vertigo induced by a rapid head position change, associated with a characteristic paroxysmal positional nystagmus. Canalolithiasis of the posterior semicircular canal is considered the most convincing theory of its pathogenesis and the development of appropriate therapeutic maneuvers resulted in its effective treatment. However, involvement of the horizontal or the anterior canal has been found in a significant rate and the recognition and treatment of these variants completed the clinical picture of the disease. MD is a chronic condition characterized by episodic attacks of vertigo, fluctuating hearing loss, tinnitus, aural pressure and a progressive loss of audiovestibular functions. Presence of endolymphatic hydrops on postmortem examination is its pathologic correlate. MD continues to be a diagnostic and therapeutic challenge. Patients with the disease range from minimally symptomatic, highly functional individuals to severely affected, disabled patients. Current management strategies are designed to control the acute and recurrent vestibulopathy but offer minimal remedy for the progressive cochlear dysfunction. VN is the most common cause of acute spontaneous vertigo, attributed to acute unilateral loss of vestibular function. Key signs and symptoms are an acute onset of spinning vertigo, postural imbalance and nausea as well as a horizontal rotatory nystagmus beating towards the non-affected side, a pathological headimpulse test and no evidence for central vestibular or ocular motor dysfunction. Vestibular neuritis preferentially involves the superior vestibular labyrinth and its afferents. Symptomatic medication is indicated only during the acute phase to relieve the vertigo and nausea

  10. True and common balsams

    Directory of Open Access Journals (Sweden)

    Dayana L. Custódio


    Full Text Available Balsams have been used since ancient times, due to their therapeutic and healing properties; in the perfume industry, they are used as fixatives, and in the cosmetics industry and in cookery, they are used as preservatives and aromatizers. They are generally defined as vegetable material with highly aromatic properties that supposedly have the ability to heal diseases, not only of the body, but also of the soul. When viewed according to this concept, many substances can be considered balsams. A more modern concept is based on its chemical composition and origin: a secretion or exudate of plants that contain cinnamic and benzoic acids, and their derivatives, in their composition. The most common naturally-occurring balsams (i.e. true balsams are the Benzoins, Liquid Storaque and the Balsams of Tolu and Peru. Many other aromatic exudates, such as Copaiba Oil and Canada Balsam, are wrongly called balsam. These usually belong to other classes of natural products, such as essential oils, resins and oleoresins. Despite the understanding of some plants, many plants are still called balsams. This article presents a chemical and pharmacological review of the most common balsams.

  12. Common Sense Biblical Hermeneutics

    Directory of Open Access Journals (Sweden)

    Michael B. Mangini


    Full Text Available Since the noetics of moderate realism provide a firm foundation upon which to build a hermeneutic of common sense, in the first part of his paper the author adopts Thomas Howe’s argument that the noetical aspect of moderate realism is a necessary condition for correct, universally valid biblical interpretation, but he adds, “insofar as it gives us hope in discovering the true meaning of a given passage.” In the second part, the author relies on John Deely’s work to show how semiotics may help interpreters go beyond meaning and seek the significance of the persons, places, events, ideas, etc., of which the meaning of the text has presented as objects to be interpreted. It is in significance that the unity of Scripture is found. The chief aim is what every passage of the Bible signifies. Considered as a genus, Scripture is composed of many parts/species that are ordered to a chief aim. This is the structure of common sense hermeneutics; therefore in the third part the author restates Peter Redpath’s exposition of Aristotle and St. Thomas’s ontology of the one and the many and analogously applies it to the question of how an exegete can discern the proper significance and faithfully interpret the word of God.

    ESO CPL Development Team


    The Common Pipeline Library (CPL) is a set of ISO-C libraries that provide a comprehensive, efficient and robust software toolkit to create automated astronomical data reduction pipelines. Though initially developed as a standardized way to build VLT instrument pipelines, the CPL may be more generally applied to any similar application. The code also provides a variety of general purpose image- and signal-processing functions, making it an excellent framework for the creation of more generic data handling packages. The CPL handles low-level data types (images, tables, matrices, strings, property lists, etc.) and medium-level data access methods (a simple data abstraction layer for FITS files). It also provides table organization and manipulation, keyword/value handling and management, and support for dynamic loading of recipe modules using programs such as EsoRex (ascl:1504.003).

  14. Common Superficial Bursitis. (United States)

    Khodaee, Morteza


    Superficial bursitis most often occurs in the olecranon and prepatellar bursae. Less common locations are the superficial infrapatellar and subcutaneous (superficial) calcaneal bursae. Chronic microtrauma (e.g., kneeling on the prepatellar bursa) is the most common cause of superficial bursitis. Other causes include acute trauma/hemorrhage, inflammatory disorders such as gout or rheumatoid arthritis, and infection (septic bursitis). Diagnosis is usually based on clinical presentation, with a particular focus on signs of septic bursitis. Ultrasonography can help distinguish bursitis from cellulitis. Blood testing (white blood cell count, inflammatory markers) and magnetic resonance imaging can help distinguish infectious from noninfectious causes. If infection is suspected, bursal aspiration should be performed and fluid examined using Gram stain, crystal analysis, glucose measurement, blood cell count, and culture. Management depends on the type of bursitis. Acute traumatic/hemorrhagic bursitis is treated conservatively with ice, elevation, rest, and analgesics; aspiration may shorten the duration of symptoms. Chronic microtraumatic bursitis should be treated conservatively, and the underlying cause addressed. Bursal aspiration of microtraumatic bursitis is generally not recommended because of the risk of iatrogenic septic bursitis. Although intrabursal corticosteroid injections are sometimes used to treat microtraumatic bursitis, high-quality evidence demonstrating any benefit is unavailable. Chronic inflammatory bursitis (e.g., gout, rheumatoid arthritis) is treated by addressing the underlying condition, and intrabursal corticosteroid injections are often used. For septic bursitis, antibiotics effective against Staphylococcus aureus are generally the initial treatment, with surgery reserved for bursitis not responsive to antibiotics or for recurrent cases. Outpatient antibiotics may be considered in those who are not acutely ill; patients who are acutely ill

  15. Reformulating the commons

    Directory of Open Access Journals (Sweden)

    Ostrom Elinor


    Full Text Available The western hemisphere is richly endowed with a diversity of natural resource systems that are governed by complex local and national institutional arrangements that have not, until recently, been well understood. While many local communities that possess a high degree of autonomy to govern local resources have been highly successful over long periods of time, others fail to take action to prevent overuse and degradation of forests, inshore fisheries, and other natural resources. The conventional theory used to predict and explain how local users will relate to resources that they share makes a uniform prediction that users themselves will be unable to extricate themselves from the tragedy of the commons. Using this theoretical view of the world, there is no variance in the performance of self-organized groups. In theory, there are no self-organized groups. Empirical evidence tells us, however, that considerable variance in performance exists and many more local users self-organize and are more successful than it is consistent with the conventional theory . Parts of a new theory are presented here.

  17. Threads of common knowledge. (United States)

    Icamina, P


    Indigenous knowledge is examined as it is affected by development and scientific exploration. The indigenous culture of shamanism, which originated in northern and southeast Asia, is a "political and religious technique for managing societies through rituals, myths, and world views." There is respect for the natural environment and community life as a social common good. This world view is still practiced by many in Latin America and in Colombia specifically. Colombian shamanism has an environmental accounting system, but the Brazilian government has established its own system of land tenure and political representation which does not adequately represent shamanism. In 1992 a conference was held in the Philippines by the International Institute for Rural Reconstruction and IDRC on sustainable development and indigenous knowledge. The link between the two is necessary. Unfortunately, there are already examples in the Philippines of loss of traditional crop diversity after the introduction of modern farming techniques and new crop varieties. An attempt was made to collect species, but without proper identification. Opposition was expressed to the preservation of wilderness preserves; the desire was to allow indigenous people to maintain their homeland and use their time-tested sustainable resource management strategies. Property rights were also discussed during the conference. Of particular concern was the protection of knowledge rights about biological diversity or pharmaceutical properties of indigenous plant species. The original owners and keepers of the knowledge must retain access and control. The research gaps were identified and found to be expansive. Reference was made to a study of Mexican Indian children who knew 138 plant species while non-Indian children knew only 37. Sometimes there is conflict of interest where foresters prefer timber forests and farmers desire fuelwood supplies and fodder and grazing land, which is provided by shrubland. Information

  18. Cofunctional Subpathways Were Regulated by Transcription Factor with Common Motif, Common Family, or Common Tissue

    Directory of Open Access Journals (Sweden)

    Fei Su


    Full Text Available Dissecting the characteristics of the transcription factor (TF regulatory subpathway is helpful for understanding the TF underlying regulatory function in complex biological systems. To gain insight into the influence of TFs on their regulatory subpathways, we constructed a global TF-subpathways network (TSN to analyze systematically the regulatory effect of common-motif, common-family, or common-tissue TFs on subpathways. We performed cluster analysis to show that the common-motif, common-family, or common-tissue TFs that regulated the same pathway classes tended to cluster together and contribute to the same biological function that led to disease initiation and progression. We analyzed the Jaccard coefficient to show that the functional consistency of subpathways regulated by the TF pairs with common motif, common family, or common tissue was significantly greater than the random TF pairs at the subpathway level, pathway level, and pathway class level. For example, HNF4A (hepatocyte nuclear factor 4, alpha and NR1I3 (nuclear receptor subfamily 1, group I, member 3 were a pair of TFs with common motif, common family, and common tissue. They were involved in drug metabolism pathways and were liver-specific factors required for physiological transcription. In short, we inferred that the cofunctional subpathways were regulated by common-motif, common-family, or common-tissue TFs.

  2. Five Theses on the Common

    Directory of Open Access Journals (Sweden)

    Gigi Roggero


    Full Text Available I present five theses on the common within the context of the transformations of capitalist social relations as well as their contemporary global crisis. My framework involves ‘‘cognitive capitalism,’’ new processes of class composition, and the production of living knowledge and subjectivity. The commons is often discussed today in reference to the privatizationand commodification of ‘‘common goods.’’ This suggests a naturalistic and conservative image of the common, unhooked from the relations of production. I distinguish between commons and the common: the first model is related to Karl Polanyi, the second to Karl Marx. As elaborated in the postoperaista debate, the common assumes an antagonistic double status: it is boththe plane of the autonomy of living labor and it is subjected to capitalist ‘‘capture.’’ Consequently, what is at stake is not the conservation of ‘‘commons,’’ but rather the production of the common and its organization into new institutions that would take us beyond the exhausted dialectic between public and private.

  3. Decadal trends in polycyclic aromatic hydrocarbon (PAH contamination assessed by 1-hydroxypyrene in fish bile fluid in the Netherlands: declining in marine waters but still a concern in estuaries

    Directory of Open Access Journals (Sweden)

    A. Dick Vethaak


    Full Text Available Long-term monitoring data on the concentrations of biliary 1-hydroxypyrene (1-OHPyr in flatfish, as a biomarker for polycyclic aromatic hydrocarbon (PAH exposure, were analysed and evaluated to elucidate spatial differences and temporal trends in marine and estuarine PAH contamination in the Netherlands. Dab (Limanda limanda and flounder (Platichthys flesus with partly overlapping distributions were used as target species. In total 1831 bile samples were analysed individually: 417 dab in 1998-2005 and 1438 flounder in 1996-2012. The sampling procedure for flatfish and the PAH metabolites determination by means of high performance liquid chromatography (HPLC with fluorescence (FL detection were based on international guidelines. Measuring the absorbance at 380 nm was tested to correct for possible differences in feeding status, but this turned out not to be a suitable parameter for the standardisation of PAH metabolite concentrations. Both fish species showed statistically significant differences in biliary 1-OHPyr concentrations between various locations. The highest level of PAH contamination was found in flounder from the estuarine Western Scheldt, which might be partly due to local dredging activities. Dab from the central North Sea (Dogger Bank showed the lowest level of PAH contamination. Analysis of all the data indicated mainly downward trends in PAH contamination, most clearly pronounced in the Dutch Wadden Sea. PAH exposure levels in the Dutch coastal waters including the Eastern Scheldt and the Wadden Sea, and also at the offshore North Sea monitoring sites represent levels of response that are not indicative of significant harm. In contrast, PAH contamination in the more industrialised Dutch estuaries (Western Scheldt and Ems Dollard is still a cause for concern. Future monitoring should register the total bile volume, the sex of the fish and the method of fishing to improve the interpretation of the data. In addition, the biliary

    Agreed strategy is to govern common cause failures by the application of diversity, to assure that the overall plant safety objectives are met even in the case that a common cause failure of a system with all redundant trains is assumed. The presented strategy aims on the application of functional diversity without the implementation of equipment diversity. In the focus are the design criteria which have to be met for the design of independent systems in such a way that the time-correlated failure of such independent systems according a common cause can be excluded deterministically.

  8. Adolescents' theories of the commons. (United States)

    Flanagan, Constance; Gallay, Erin


    Drawing from research on civic engagement and environmental commitment, we make a case for the processes inherent in how adolescents' ideas about the commons (those things that bind a polity together) develop. Engagement in the public realm with a plethora of perspectives and a goal of finding common ground is fundamental. Adolescents participate in the public realm through mini-polities (e.g., schools, community organizations). Practices in those settings can reinforce or challenge dominant political narratives. Special attention is given to the natural environment as a commons that transcends generations and to the opportunities in schools and in community partnerships that enable adolescents to realize their interdependence with nature and to author decisions about the commons.

  19. Forest commons and local enforcement. (United States)

    Chhatre, Ashwini; Agrawal, Arun


    This article examines the relationship between local enforcement and forests used as commons. It uses a unique multicountry dataset, created over the past 15 years by the International Forestry Resources and Institutions Research Program. Drawing on original enforcement and forest commons data from 9 countries, we find that higher levels of local enforcement have a strong and positive but complex relationship to the probability of forest regeneration. This relationship holds even when the influence of a number of other factors such as user group size, subsistence, and commercial importance of forests, size of forest, and collective action for forest improvement activities is taken into account. Although several of the above factors have a statistically significant relationship to changes in the condition of forest commons, differences in levels of local enforcement strongly moderate their link with forest commons outcomes. The research, using data from diverse political, social, and ecological contexts, shows both the importance of enforcement to forest commons and some of the limits of forest governance through commons arrangements.

  20. Casuistry as common law morality. (United States)

    Paulo, Norbert


    This article elaborates on the relation between ethical casuistry and common law reasoning. Despite the frequent talk of casuistry as common law morality, remarks on this issue largely remain at the purely metaphorical level. The article outlines and scrutinizes Albert Jonsen and Stephen Toulmin's version of casuistry and its basic elements. Drawing lessons for casuistry from common law reasoning, it is argued that one generally has to be faithful to ethical paradigms. There are, however, limitations for the binding force of paradigms. The most important limitations--the possibilities of overruling and distinguishing paradigm norms--are similar in common law and in casuistry, or so it is argued. These limitations explain why casuistry is not necessarily overly conservative and conventional, which is one line of criticism to which casuists can now better respond. Another line of criticism has it that the very reasoning from case to case is extremely unclear in casuistry. I suggest a certain model of analogical reasoning to address this critique. All my suggestions to understand and to enhance casuistry make use of common law reasoning whilst remaining faithful to Jonsen and Toulmin's main ideas and commitments. Further developed along these lines, casuistry can appropriately be called "common law morality."

    With the enhancement in the awareness of self-diagnosis among residents, it's very common for each family to prepare common medicines for unexpected needs. Meanwhile, with the popularization of the traditional Chinese medicine knowledge, the proportion of common traditional Chinese medicines prepared at residents' families is increasingly higher than western medicines year by year. To make it clear, both pre-research and closed questionnaire research were adopted for residents in Chaoyang District, Beijing, excluding residents with a medical background. Based on the results of data, a analysis was made to define the role and influence on the quality of life of residents and give suggestions for relevant departments to improve the traditional Chinese medicine popularization and promote the traditional Chinese medicine market.

    Problems of discipline are common among parents. These may be the results of the parents' pitfalls in disciplining their children. To find out common pitfalls of parents in disciplining their children. Parents of students with ages ranged between 60-72 months old in Bangkok-Noi district, Bangkok, were selected by random sampling. Total number of 1947 children ages between 60-72 months were recruited. Parents of these children were interviewed with a questionnaire designed to probe into problems in child rearing. There hindered and fifty questionnaires were used for data analyses. Parents had high concerns about problems in discipline their children and needed support from professional personnel. They had limited knowledge and possessed lots of wrong attitude towards discipline. Common pitfalls on the topics were problems in, 1) limit setting 2) rewarding and punishment 3) supervision on children watching TV and bedtime routines. Parents of children with ages 60-72 months old in Bangkok-Noi district, Bangkok, had several common pitfalls in disciplining their children, including attitude, knowledge and practice.

  9. Common sleep disorders in children. (United States)

    Carter, Kevin A; Hathaway, Nathanael E; Lettieri, Christine F


    Up to 50% of children will experience a sleep problem. Early identification of sleep problems may prevent negative consequences, such as daytime sleepiness, irritability, behavioral problems, learning difficulties, motor vehicle crashes in teenagers, and poor academic performance. Obstructive sleep apnea occurs in 1% to 5% of children. Polysomnography is needed to diagnose the condition because it may not be detected through history and physical examination alone. Adenotonsillectomy is the primary treatment for most children with obstructive sleep apnea. Parasomnias are common in childhood; sleepwalking, sleep talking, confusional arousals, and sleep terrors tend to occur in the first half of the night, whereas nightmares are more common in the second half of the night. Only 4% of parasomnias will persist past adolescence; thus, the best management is parental reassurance and proper safety measures. Behavioral insomnia of childhood is common and is characterized by a learned inability to fall and/or stay asleep. Management begins with consistent implementation of good sleep hygiene practices, and, in some cases, use of extinction techniques may be appropriate. Delayed sleep phase disorder is most common in adolescence, presenting as difficulty falling asleep and awakening at socially acceptable times. Treatment involves good sleep hygiene and a consistent sleep-wake schedule, with nighttime melatonin and/or morning bright light therapy as needed. Diagnosing restless legs syndrome in children can be difficult; management focuses on trigger avoidance and treatment of iron deficiency, if present.

  10. Antihistamines for the common cold. (United States)

    De Sutter, An I M; Saraswat, Avadhesh; van Driel, Mieke L


    The common cold is an upper respiratory tract infection, most commonly caused by a rhinovirus. It affects people of all age groups and although in most cases it is self limiting, the common cold still causes significant morbidity. Antihistamines are commonly offered over the counter to relieve symptoms for patients affected by the common cold, however there is not much evidence of their efficacy. To assess the effects of antihistamines on the common cold. We searched CENTRAL (2015, Issue 6), MEDLINE (1948 to July week 4, 2015), EMBASE (2010 to August 2015), CINAHL (1981 to August 2015), LILACS (1982 to August 2015) and Biosis Previews (1985 to August 2015). We selected randomised controlled trials (RCTs) using antihistamines as monotherapy for the common cold. We excluded any studies with combination therapy or using antihistamines in patients with an allergic component in their illness. Two authors independently assessed trial quality and extracted data. We collected adverse effects information from the included trials. We included 18 RCTs, which were reported in 17 publications (one publication reports on two trials) with 4342 participants (of which 212 were children) suffering from the common cold, both naturally occurring and experimentally induced. The interventions consisted of an antihistamine as monotherapy compared with placebo. In adults there was a short-term beneficial effect of antihistamines on severity of overall symptoms: on day one or two of treatment 45% had a beneficial effect with antihistamines versus 38% with placebo (odds ratio (OR) 0.74, 95% confidence interval (CI) 0.60 to 0.92). However, there was no difference between antihistamines and placebo in the mid term (three to four days) to long term (six to 10 days). When evaluating individual symptoms such as nasal congestion, rhinorrhoea and sneezing, there was some beneficial effect of the sedating antihistamines compared to placebo (e.g. rhinorrhoea on day three: mean difference (MD) -0

  11. Lipedema: A Relatively Common Disease with Extremely Common Misconceptions. (United States)

    Buck, Donald W; Herbst, Karen L


    Lipedema, or adiposis dolorosa, is a common adipose tissue disorder that is believed to affect nearly 11% of adult women worldwide. It is characterized most commonly by disproportionate adipocyte hypertrophy of the lower extremities, significant tenderness to palpation, and a failure to respond to extreme weight loss modalities. Women with lipedema report a rapid growth of the lipedema subcutaneous adipose tissue in the setting of stress, surgery, and/or hormonal changes. Women with later stages of lipedema have a classic "column leg" appearance, with masses of nodular fat, easy bruising, and pain. Despite this relatively common disease, there are few physicians who are aware of it. As a result, patients are often misdiagnosed with lifestyle-induced obesity, and/or lymphedema, and subjected to unnecessary medical interventions and fat-shaming. Diagnosis is largely clinical and based on criteria initially established in 1951. Treatment of lipedema is effective and includes lymphatic support, such as complete decongestive therapy, and specialized suction lipectomy to spare injury to lymphatic channels and remove the diseased lipedema fat. With an incidence that may affect nearly 1 in 9 adult women, it is important to generate appropriate awareness, conduct additional research, and identify better diagnostic and treatment modalities for lipedema so these women can obtain the care that they need and deserve.

  12. Common criteria for usability review. (United States)

    Nassar, Victor


    The propose of this paper is to present a literature review, in a grouping of common criteria for usability approaches of Bastien and Scapin (1993), Nielsen (1994), Shnneiderman(1998), Dix et al (1998), Preece et al (2005) and ISO 9241-110 (2006). After establishment of prerequisites for knowledge of the general characteristics of the users who will use the system, are defined and explained the criteria in common: consistency, user control, ease of learning, flexibility, errors management, reduction of excess and visibility system status. Although there is no determination as to which criteria should be considered when developing an interface and each author presents some specificity in their approach, it is observed that there is equivalence in the measures adopted usability.

  13. Common Readout System in ALICE

    Jubin, Mitra


    The ALICE experiment at the CERN Large Hadron Collider is going for a major physics upgrade in 2018. This upgrade is necessary for getting high statistics and high precision measurement for probing into rare physics channels needed to understand the dynamics of the condensed phase of QCD. The high interaction rate and the large event size in the upgraded detectors will result in an experimental data flow traffic of about 1 TB/s from the detectors to the on-line computing system. A dedicated Common Readout Unit (CRU) is proposed for data concentration, multiplexing, and trigger distribution. CRU, as common interface unit, handles timing, data and control signals between on-detector systems and online-offline computing system. An overview of the CRU architecture is presented in this manuscript.

  17. George Combe and common sense. (United States)

    Dyde, Sean


    This article examines the history of two fields of enquiry in late eighteenth- and early nineteenth-century Scotland: the rise and fall of the common sense school of philosophy and phrenology as presented in the works of George Combe. Although many previous historians have construed these histories as separate, indeed sometimes incommensurate, I propose that their paths were intertwined to a greater extent than has previously been given credit. The philosophy of common sense was a response to problems raised by Enlightenment thinkers, particularly David Hume, and spurred a theory of the mind and its mode of study. In order to succeed, or even to be considered a rival of these established understandings, phrenologists adapted their arguments for the sake of engaging in philosophical dispute. I argue that this debate contributed to the relative success of these groups: phrenology as a well-known historical subject, common sense now largely forgotten. Moreover, this history seeks to question the place of phrenology within the sciences of mind in nineteenth-century Britain.

  18. Sustainability of common pool resources. (United States)

    Timilsina, Raja Rajendra; Kotani, Koji; Kamijo, Yoshio


    Sustainability has become a key issue in managing natural resources together with growing concerns for capitalism, environmental and resource problems. We hypothesize that the ongoing modernization of competitive societies, which we refer to as "capitalism," affects human nature for utilizing common pool resources, thus compromising sustainability. To test this hypothesis, we design and implement a set of dynamic common pool resource games and experiments in the following two types of Nepalese areas: (i) rural (non-capitalistic) and (ii) urban (capitalistic) areas. We find that a proportion of prosocial individuals in urban areas is lower than that in rural areas, and urban residents deplete resources more quickly than rural residents. The composition of proself and prosocial individuals in a group and the degree of capitalism are crucial in that an increase in prosocial members in a group and the rural dummy positively affect resource sustainability by 65% and 63%, respectively. Overall, this paper shows that when societies move toward more capitalistic environments, the sustainability of common pool resources tends to decrease with the changes in individual preferences, social norms, customs and views to others through human interactions. This result implies that individuals may be losing their coordination abilities for social dilemmas of resource sustainability in capitalistic societies.

  19. Common Ground Between Three Cultures

    Yehuda Peled


    Full Text Available The Triwizard program with Israel brought together students from three different communities: an Israeli Arab school, an Israeli Jewish school, and an American public school with few Jews and even fewer Muslims. The two Israeli groups met in Israel to find common ground and overcome their differences through dialogue and understanding. They communicated with the American school via technology such as video-conferencing, Skype, and emails. The program culminated with a visit to the U.S. The goal of the program was to embark upon a process that would bring about intercultural awareness and acceptance at the subjective level, guiding all involved to develop empathy and an insider's view of the other's culture. It was an attempt to have a group of Israeli high school students and a group of Arab Israeli students who had a fearful, distrustful perception of each other find common ground and become friends. TriWizard was designed to have participants begin a dialogue about issues, beliefs, and emotions based on the premise that cross-cultural training strategies that are effective in changing knowledge are those that engage the emotions, and actively develop empathy and an insider's views of another culture focused on what they have in common. Participants learned that they could become friends despite their cultural differences.

  20. Scientific Research: Commodities or Commons? (United States)

    Vermeir, Koen


    Truth is for sale today, some critics claim. The increased commodification of science corrupts it, scientific fraud is rampant and the age-old trust in science is shattered. This cynical view, although gaining in prominence, does not explain very well the surprising motivation and integrity that is still central to the scientific life. Although scientific knowledge becomes more and more treated as a commodity or as a product that is for sale, a central part of academic scientific practice is still organized according to different principles. In this paper, I critically analyze alternative models for understanding the organization of knowledge, such as the idea of the scientific commons and the gift economy of science. After weighing the diverse positive and negative aspects of free market economies of science and gift economies of science, a commons structured as a gift economy seems best suited to preserve and take advantage of the specific character of scientific knowledge. Furthermore, commons and gift economies promote the rich social texture that is important for supporting central norms of science. Some of these basic norms might break down if the gift character of science is lost. To conclude, I consider the possibility and desirability of hybrid economies of academic science, which combine aspects of gift economies and free market economies. The aim of this paper is to gain a better understanding of these deeper structural challenges faced by science policy. Such theoretical reflections should eventually assist us in formulating new policy guidelines.

    Full Text Available The world population has doubled since the 60’s, now reaching 7 billion – it is estimated it will continue growing. If in more advanced economies, the population is starting to grow old and even reduce in numbers, in less developed countries, population numbers are registering a fast growth. Across the world, the ecosystems are exposed to critical levels of pollution in more and more complex combinations. Human activities, population growth and shifting patterns in consumer nature are the main factors that are at the base of thin ever-growing burden on our environment. Globalization means that the consumer and production patterns from a country or a region contribute to the pressures on the environment in totally different parts of the world. With the rise of environmental problems, the search for solutions also begun, such as methods and actions aimed to protect the environment and to lead to a better correlation between economic growth and the environment. The common goals of these endeavors from participating states was to come up with medium and long term regulations that would lead to successfully solving environmental issues. In this paper, we have analyzed the way in which countries started collaborating in the 1970’s at an international level in order to come up with a common policy that would have a positive impact on the environment. The European Union has come up with its own common policy, a policy that each member state must implement. In this context, Romania has developed its National Strategy for Waste Management, a program that Romania wishes to use to reduce the quantity of waste and better dispose of it.

    Full Text Available An ASQS(v is a particular Steiner system featuring a set of v vertices and two separate families of blocks, B and G, whose elements have a respective cardinality of 4 and 6. It has the property that any three vertices of X belong either to a B-block or to a G-block. The parameter cb is the number of common blocks in two separate ASQSs, both defined on the same set of vertices X . In this paper it is shown that cb ≤ 29 for any pair of ASQSs(12.

  5. Management of common sleep disorders. (United States)

    Ramar, Kannan; Olson, Eric J


    Sleep disorders are common and affect sleep quality and quantity, leading to increased morbidity. Patients with sleep disorders can be categorized as those who cannot sleep, those who will not sleep, those with excessive daytime sleepiness, and those with increased movements during sleep. Insomnia, defined as difficulty initiating or maintaining sleep that results in daytime impairment, is diagnosed using history findings and treated with cognitive behavior therapy, with or without sleep hypnotics. Restless legs syndrome is characterized by an urge to move the legs that worsens with rest, is relieved by movement, and often occurs in the evening or at night. Restless legs syndrome is treated based on the frequency of symptoms. Narcolepsy is characterized by excessive sleepiness, cataplexy, hypnagogic or hypnopompic hallucinations, and sleep paralysis. It is diagnosed using a sleep log or actigraphy, followed by overnight polysomnography and a multiple sleep latency test. Narcolepsy is treated with stimulants, such as modafinil; selective serotonin reuptake inhibitors; or gamma hydroxybutyric acid (sodium oxybate). Patients with snoring and witnessed apneas may have obstructive sleep apnea, which is diagnosed using overnight polysomnography. Continuous positive airway pressure is the most common and effective treatment for obstructive sleep apnea. Rapid eye movement sleep behavior disorder is characterized by increased muscle tone during rapid eye movement sleep, resulting in the patient acting out dreams with possible harmful consequences. It is diagnosed based on history and polysomnography findings, and treated with environmental safety measures and melatonin or clonazepam.

  6. Urban ambiances as common ground?

    Directory of Open Access Journals (Sweden)

    Jean-Paul Thibaud


    Full Text Available The aim of this paper is to point out various arguments which question ambiance as a common ground of everyday urban experience. Such a project involves four major points. First, we have to move beyond the exclusive practical aspects of everyday life and bring the sensory to the forefront. Under such conditions, sensory cultures emerge where feeling and acting come together. Second, we must put common experience into perspectiveby initiating a dual dynamics of socialising the sensory and sensitising social life. Ambiances involve a complex web comprised of an ‘existential’ dimension (empathy with the ambient world, a ‘contextual’ dimension (degree of presence in the situation, and an ‘interactional’ dimension (forms of sociability expressed in the tonality. Third, we have to initiate a political ecology of ambiances in order to better understand how ambiances deal with fundamental design and planning issues. Far from being neutral, the notion of ambiance appears to be bound up with the socio-aesthetic strategies underpinning changes to the sensory urban environment of the future. Fourth, we have to question what in situ experience is all about. Three major research pointers enable to address this issue: the embodiment of situated experiences, the porous nature of sensory spaces, and the sensory efficiency of the build environment. Ambiances sensitize urban design as well as social lifeforms.

  7. Network Governance of the Commons

    Directory of Open Access Journals (Sweden)

    Lars Gunnar Carlsson


    Full Text Available The survival of the commons is closely associated with the potential to find ways to strengthen contemporary management systems, making them more responsive to a number of complexities, like the dynamics of ecosystems and related, but often fragmented, institutions. A discussion on the desirability of finding ways to establish so-called cross-scale linkages has recently been vitalised in the literature. In the same vein, concepts like adaptive management, co-management and adaptive co-management have been discussed. In essence, these ways of organizing management incorporate an implicit assumption about the establishment of social networks and is more closely related to network governance and social network theory, than to political administrative hierarchy. However, so far, attempts to incorporate social network analysis (SNA in this literature have been rather few, and not particularly elaborate. In this paper, a framework for such an approach will be presented. The framework provides an analytical skeleton for the understanding of joint management and the establishment of cross-scale linkages. The relationships between structural network properties - like density, centrality and heterogeneity - and innovation in adaptive co-management systems are highlighted as important to consider when crafting institutions for natural resource management. The paper makes a theoretical and methodological contribution to the understanding of co-management, and thereby to the survival of the commons.

  8. Correlations between benthic habitats and demersal fish assemblages — A case study on the Dogger Bank (North Sea) (United States)

    Sell, Anne F.; Kröncke, Ingrid


    The interdependence between groundfish assemblages and habitat properties was investigated on the Dogger Bank in the North Sea. Abiotic habitat parameters considered included topography, hydrographic conditions, sediment composition, and the biotic habitat variable the prevailing benthic invertebrates. Distinct epi- and infauna communities occurred at different locations on the Dogger Bank. Fish assemblages were clearly linked to both the biotic and abiotic habitat characteristics. Overall, fish and benthic communities revealed similar spatial distribution, represented in the respective clusters of characteristic and abundant species. Distribution patterns corresponded with the prevailing abiotic conditions such as depth and sediment composition, which appear to relate to autecological preferences of individual species. The apparently most generalist species, grey gurnard (Eutrigla gurnardus) and dab (Limanda limanda) occurred at all stations and dominated in terms of biomass in most cases. The absolute numbers of grey gurnards were related to the abundance of suitable prey, invertebrate and fish species, which stomach analyses revealed as part of the diet in an independent study during the same research cruise. Haddock (Melanogrammus aeglefinus) and whiting (Merlangius merlangus) were only abundant at deep stations along the flanks of the bank. The occurrence of lemon sole (Microstomus kitt), American plaice (Hippoglossoides platessoides) and cod (Gadus morhua) was also positively correlated with depth, whereas especially lesser weever (Echiichthys vipera), sandeel species and solenette (Buglossidium luteum) occurred predominantly at the shallower sites. At the same time, individual fish species such as solenette and lesser weever were associated with high densities of selected epi- or infauna species.

  9. Common Β- Thalassaemia Mutations in

    Directory of Open Access Journals (Sweden)

    P Azarfam


    Full Text Available Introduction: β –Thalassaemia was first explained by Thomas Cooly as Cooly’s anaemia in 1925. The β- thalassaemias are hereditary autosomal disorders with decreased or absent β-globin chain synthesis. The most common genetic defects in β-thalassaemias are caused by point mutations, micro deletions or insertions within the β-globin gene. Material and Methods: In this research , 142 blood samples (64 from childrens hospital of Tabriz , 15 samples from Shahid Gazi hospital of Tabriz , 18 from Urumia and 45 samples from Aliasghar hospital of Ardebil were taken from thalassaemic patients (who were previously diagnosed .Then 117 non-familial samples were selected . The DNA of the lymphocytes of blood samples was extracted by boiling and Proteinase K- SDS procedure, and mutations were detected by ARMS-PCR methods. Results: From the results obtained, eleven most common mutations,most of which were Mediterranean mutations were detected as follows; IVS-I-110(G-A, IVS-I-1(G-A ،IVS-I-5(G-C ,Frameshift Codon 44 (-C,( codon5(-CT,IVS-1-6(T-C, IVS-I-25(-25bp del ,Frameshift 8.9 (+G ,IVS-II-1(G-A ,Codon 39(C-T, Codon 30(G-C the mutations of the samples were defined. The results showed that Frameshift 8.9 (+G, IVS-I-110 (G-A ,IVS-II-I(G-A, IVS-I-5(G-C, IVS-I-1(G-A , Frameshift Codon 44(-C , codon5(-CT , IVS-1-6(T-C , IVS-I-25(-25bp del with a frequency of 29.9%, 25.47%,17.83%, 7.00%, 6.36% , 6.63% , 3.8% , 2.5% , 0.63% represented the most common mutations in North - west Iran. No mutations in Codon 39(C-T and Codon 30(G-C were detected. Cunclusion: The frequency of the same mutations in patients from North - West of Iran seems to be different as compared to other regions like Turkey, Pakistan, Lebanon and Fars province of Iran. The pattern of mutations in this region is more or less the same as in the Mediterranean region, but different from South west Asia and East Asia.

  10. Harvesting NASA's Common Metadata Repository (United States)

    Shum, D.; Mitchell, A. E.; Durbin, C.; Norton, J.


    As part of NASA's Earth Observing System Data and Information System (EOSDIS), the Common Metadata Repository (CMR) stores metadata for over 30,000 datasets from both NASA and international providers along with over 300M granules. This metadata enables sub-second discovery and facilitates data access. While the CMR offers a robust temporal, spatial and keyword search functionality to the general public and international community, it is sometimes more desirable for international partners to harvest the CMR metadata and merge the CMR metadata into a partner's existing metadata repository. This poster will focus on best practices to follow when harvesting CMR metadata to ensure that any changes made to the CMR can also be updated in a partner's own repository. Additionally, since each partner has distinct metadata formats they are able to consume, the best practices will also include guidance on retrieving the metadata in the desired metadata format using CMR's Unified Metadata Model translation software.

  11. Spatial and annual variation in fecundity and oocyte atresia of yellowtail flounder, Limanda ferruginea, in U.S. waters (United States)

    McElroy, W. David; Wuenschel, Mark J.; Towle, Emilee K.; McBride, Richard S.


    Potential annual fecundity (PAF) was estimated over three years (2010-2012) for yellowtail flounder with individuals from the three stocks off the northeast U.S. coast. Down-regulation of PAF, the resorption of oocytes during development, was evident as the vitellogenic cohort advanced, so we directly measured atresia of vitellogenic oocytes using stereological techniques. PAF models including relative fish condition, stock area, year, and oocyte diameter of the leading cohort explained more variation than models with just size alone based on Akaike information criteria. In a given year, Gulf of Maine females had lower PAF at size than southern New England females. Interannual differences were evident: PAF of both stocks was higher in 2010 and lower in 2012, with 2011 showing less synchronization between these stocks. Differences in size at age and relative condition suggested that energy available for somatic and reproductive growth was lower in some years in the Gulf of Maine and Georges Bank, especially in 2011. Georges Bank PAF and condition were intermediate to the other stocks or more similar to the Gulf of Maine, varying annually. A latitudinal gradient in PAF is evident based on our results and relative to earlier studies that included Canadian stocks. The magnitude of down-regulation was variable across stocks and typically 3-25% of PAF. This can be accounted for in fecundity estimates, by the seasonal schedule of sampling and use of an oocyte diameter term in the fecundity model. Theoretical models of atresia patterns suggested variable rates over the later portion of clutch development. The timing of down-regulation varied among years, and its intensity was influenced by female relative condition. Fecundity was related to fish size, but was also affected by fish condition and oocyte diameter (a proxy for time until spawning), and spatial and temporal effects. A longer time series of PAF may identify environmental drivers that modulate annual stock reproductive potential.

  15. Sustainable models of audiovisual commons

    Directory of Open Access Journals (Sweden)

    Mayo Fuster Morell


    Full Text Available This paper addresses an emerging phenomenon characterized by continuous change and experimentation: the collaborative commons creation of audiovisual content online. The analysis wants to focus on models of sustainability of collaborative online creation, paying particular attention to the use of different forms of advertising. This article is an excerpt of a larger investigation, which unit of analysis are cases of Online Creation Communities that take as their central node of activity the Catalan territory. From 22 selected cases, the methodology combines quantitative analysis, through a questionnaire delivered to all cases, and qualitative analysis through face interviews conducted in 8 cases studied. The research, which conclusions we summarize in this article,in this article, leads us to conclude that the sustainability of the project depends largely on relationships of trust and interdependence between different voluntary agents, the non-monetary contributions and retributions as well as resources and infrastructure of free use. All together leads us to understand that this is and will be a very important area for the future of audiovisual content and its sustainability, which will imply changes in the policies that govern them.

  16. Common errors in disease mapping

    Directory of Open Access Journals (Sweden)

    Ricardo Ocaña-Riola


    Full Text Available Many morbid-mortality atlases and small-area studies have been carried out over the last decade. However, the methods used to draw up such research, the interpretation of results and the conclusions published are often inaccurate. Often, the proliferation of this practice has led to inefficient decision-making, implementation of inappropriate health policies and negative impact on the advancement of scientific knowledge. This paper reviews the most frequent errors in the design, analysis and interpretation of small-area epidemiological studies and proposes a diagnostic evaluation test that should enable the scientific quality of published papers to be ascertained. Nine common mistakes in disease mapping methods are discussed. From this framework, and following the theory of diagnostic evaluation, a standardised test to evaluate the scientific quality of a small-area epidemiology study has been developed. Optimal quality is achieved with the maximum score (16 points, average with a score between 8 and 15 points, and low with a score of 7 or below. A systematic evaluation of scientific papers, together with an enhanced quality in future research, will contribute towards increased efficacy in epidemiological surveillance and in health planning based on the spatio-temporal analysis of ecological information.

  19. The Common Sense of Copying

    Directory of Open Access Journals (Sweden)

    Daniel M. Stamm


    Full Text Available This essay provides a survey of two very significant phases in the history of Japanese education: 1 the founding of the modern system (1872-1890 with a focus on the pedagogical practices acquired from the United States during that period and 2 Japan’s performance on international tests of mathematics achievement. The first relies primarily on Benjamin Duke’s recently published book The History of Modern Japanese Education: Constructing the National School System, 1872-1890, and the second on a detailed comparison of ERA mathematics test scores of Japan and Singapore over a thirty year period. These two aspects provide clear evidence that, contrary to the assertions of some scholars, it is quite possible to transfer the practices in use in one culture to another, with great success. Noting the irony of the abandonment by the U.S. of the principles that have served Japan so well for almost 140 years, I suggest that we exercise the "Common Sense of Copying” ourselves.

  20. Laparoscopic common bile duct exploration. (United States)

    Shuchleib, S; Chousleb, A; Mondragon, A; Torices, E; Licona, A; Cervantes, J


    Since the introduction of laparoscopic cholecystectomy, the management of common bile duct (CBD) stones has undergone significant change. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy is now routinely done in cases where the diagnosis of choledocholithiasis is suspected preoperatively, with clearance of the bile ducts before laparoscopic cholecystectomy. Intraoperative discovery of CBD stones by cholangiography represents a challenge to the surgeon, who must make a decision about when to perform laparoscopic CBD exploration, convert to open surgery, or send the patient for ERCP during the postoperative period. Because ERCP has a definite failure rate, laparoscopic CBD exploration can be a treatment option. Among 2500 laparoscopic cholecystectomies done by our group from January 1991 to June 1997, 50 patients (2%) underwent laparoscopic CBD exploration, 13 by the transcystic technique and 37 by choledocotomy, with a conversion rate of 8% and a hospital stay of 4.3 days. One patient died from complicated pancreatitis following ERCP and unsuccessful extraction of a CBD stone. We obtained our goal of a CBD free of stones in 92% of the cases. We conclude that laparoscopic CBD exploration is an effective method for treating choledocolithiasis that allows management of this pathology in one stage, although it requires advanced laparoscopic skills and adequate equipment.

    We conduct an empirical investigation of the exposure of U.S. REIT returns to commonality in liquidity. Taking advantage of the specific characteristics of REITs, we study three types of commonality in liquidity: within-asset commonality, cross-asset commonality (with the stock market), and commonality with the underlying property market. We find evidence that the three types of commonality in liquidity represent significant risk factors for REIT returns but only during bad market conditions....

  2. Designing the Microbial Research Commons

    Energy Technology Data Exchange (ETDEWEB)

    Uhlir, Paul F. [Board on Research Data and Information Policy and Global Affairs, Washington, DC (United States)


    Recent decades have witnessed an ever-increasing range and volume of digital data. All elements of the pillars of science--whether observation, experiment, or theory and modeling--are being transformed by the continuous cycle of generation, dissemination, and use of factual information. This is even more so in terms of the re-using and re-purposing of digital scientific data beyond the original intent of the data collectors, often with dramatic results. We all know about the potential benefits and impacts of digital data, but we are also aware of the barriers, the challenges in maximizing the access, and use of such data. There is thus a need to think about how a data infrastructure can enhance capabilities for finding, using, and integrating information to accelerate discovery and innovation. How can we best implement an accessible, interoperable digital environment so that the data can be repeatedly used by a wide variety of users in different settings and with different applications? With this objective: to use the microbial communities and microbial data, literature, and the research materials themselves as a test case, the Board on Research Data and Information held an International Symposium on Designing the Microbial Research Commons at the National Academy of Sciences in Washington, DC on 8-9 October 2009. The symposium addressed topics such as models to lower the transaction costs and support access to and use of microbiological materials and digital resources from the perspective of publicly funded research, public-private interactions, and developing country concerns. The overall goal of the symposium was to stimulate more research and implementation of improved legal and institutional models for publicly funded research in microbiology.

  3. Coordinating towards a Common Good (United States)

    Santos, Francisco C.; Pacheco, Jorge M.


    Throughout their life, humans often engage in collective endeavors ranging from family related issues to global warming. In all cases, the tragedy of the commons threatens the possibility of reaching the optimal solution associated with global cooperation, a scenario predicted by theory and demonstrated by many experiments. Using the toolbox of evolutionary game theory, I will address two important aspects of evolutionary dynamics that have been neglected so far in the context of public goods games and evolution of cooperation. On one hand, the fact that often there is a threshold above which a public good is reached [1, 2]. On the other hand, the fact that individuals often participate in several games, related to the their social context and pattern of social ties, defined by a social network [3, 4, 5]. In the first case, the existence of a threshold above which collective action is materialized dictates a rich pattern of evolutionary dynamics where the direction of natural selection can be inverted compared to standard expectations. Scenarios of defector dominance, pure coordination or coexistence may arise simultaneously. Both finite and infinite population models are analyzed. In networked games, cooperation blooms whenever the act of contributing is more important than the effort contributed. In particular, the heterogeneous nature of social networks naturally induces a symmetry breaking of the dilemmas of cooperation, as contributions made by cooperators may become contingent on the social context in which the individual is embedded. This diversity in context provides an advantage to cooperators, which is particularly strong when both wealth and social ties follow a power-law distribution, providing clues on the self-organization of social communities. Finally, in both situations, it can be shown that individuals no longer play a defection dominance dilemma, but effectively engage in a general N-person coordination game. Even if locally defection may seem

  8. On the commons of developed industrialized countries

    Directory of Open Access Journals (Sweden)

    Erling Berge


    Full Text Available The editorial discusses the status and prospects of the commons of developed industrialized countries, based on the literature. For the traditional commons, one key variable for long-term development prospects of the commons is found in the way ownership to the commons is structured. A second key variable is the way increasing knowledge, including scientific environmental knowledge, has affected our perception of what a resource is within a commons and its value. The way these two variables characterizing commons: “structure of ownership” and “knowledge of valuable resources” are related is illustrated in a process referred to as “the withering away” with potential for widely diverging outcomes. Also new emerging urban commons are commented on and a more indepth study of both traditional and new urban commons is called for.

    This paper considers optimal auctions where individuals' valuations have both a private and common value component. We show that when the set of potential buyers and seller are symmetrically uninformed regarding the common value component, it may be socially optimal not to resolve this common uncertainty. Under the sufficient conditions provided to generate this outcome, efficiency will be restored in the optimal auction.

  14. Common factors of change in couple therapy. (United States)

    Davis, Sean D; Lebow, Jay L; Sprenkle, Douglas H


    Though it is clear from meta-analytic research that couple therapy works well, it is less clear how couple therapy works. Efforts to attribute change to the unique ingredients of a particular model have consistently turned up short, leading many researchers to suggest that change is due to common factors that run through different treatment approaches and settings. The purpose of this article is to provide an empirically based case for several common factors in couple therapy, and discuss clinical, training, and research implications for a common factors couple therapy paradigm. Critical distinctions between model-driven and common factors paradigms are also discussed, and a moderate common factors approach is proposed as a more useful alternative to an extreme common factors approach.

  3. Laboratories of commons: experimentation, recursivity and activism

    Directory of Open Access Journals (Sweden)

    Adolfo Estalella Fernández


    Full Text Available The urban public space, digital creations or the air, all of them are objects that have been traditionally thought within the dichotomous logic of the public and private property but in the last decade they have started to be considered as common resources. Commons is an old concept that has been recovered with intensity in the last decade; it refers to collective resources and goods that are governed collectively and whose property regime is different from the public and private. This article introduces the contributions to a monograph devoted to the topic of ‘Laboratories of commons’. Contributors discuss the diverse modalities of commons in different social domains like art, activism, the rural and the urban domain. This introduction contextualizes these contributions and identifies some of the issues that cross the different articles. In this exercise we introduce a tentative argument according to which the commons and the commons research take an exceptional configuration in Spain. Very briefly: commons are brought into existence as an epistemic object, an experimental domain quite different from the conventional conceptualizations that conceive it as a property regime or a type of good. This peculiar configuration gives a distinctive condition to commons in Spain that are different from other geographies; this is evidenced in a double shift: the emergence of new objects that are thought as commons and the location of their research in the domain of cultural and creative production.

  11. Common-cause analysis using sets

    International Nuclear Information System (INIS)

    Worrell, R.B.; Stack, D.W.


    Common-cause analysis was developed at the Aerojet Nuclear Company for studying the behavior of a system that is affected by special conditions and secondary causes. Common-cause analysis is related to fault tree analysis. Common-cause candidates are minimal cut sets whose primary events are closely linked by a special condition or are susceptible to the same secondary cause. It is shown that common-cause candidates can be identified using the Set Equation Transformation System (SETS). A Boolean equation is used to establish the special conditions and secondary cause susceptibilities for each primary event in the fault tree. A transformation of variables (substituting equals for equals), executed on a minimal cut set equation, results in replacing each primary event by the right side of its special condition/secondary cause equation and leads to the identification of the common-cause candidates

  12. Common Injuries of Collegiate Tennis Players

    Directory of Open Access Journals (Sweden)

    Christian Wisdom Magtajas Valleser


    Full Text Available The purpose of this study is to determine the common injuries of Filipino collegiate tennis players; 110 varsity tennis players with a mean of 20 years old (SD ± 1.7 with an average playing experience of 12 years participated in the study. There was a 100% occurrence of at least one injury with an average rate of 5.98 injuries per person. The authors observed that the most commonly injured anatomical region is the lower extremity; ankles were recorded as the most commonly injured part. Other commonly injured areas included the shoulders and lower back. Furthermore, the most common injury type is tendinitis, sprains, and strains. The recorded injuries were mostly associated with overuse injuries, and the findings were similar to those of most other studies on tennis injuries. A larger sample size may provide more conclusive findings on tennis injuries, particularly in different levels of competition, such as recreational or professional athletes.

  13. Chemical and Common Burns in Children. (United States)

    Yin, Shan


    Burns are a common cause of preventable morbidity and mortality in children. Thermal and chemical burns are the most common types of burns. Their clinical appearance can be similar and the treatment is largely similar. Thermal burns in children occur primarily after exposure to a hot surface or liquid, or contact with fire. Burns are typically classified based on the depth and total body surface area, and the severity and onset of the burn can also depend on the temperature and duration of contact. Chemical burns are caused by chemicals-most commonly acids and alkalis-that can damage the skin on contact. In children, the most common cause of chemical burns is from household products such as toilet bowl cleaners, drain cleaners, detergents, and bleaches. Mild chemical burns generally cause redness and pain and can look similar to other common rashes or skin infections, whereas severe chemical burns are more extreme and may cause redness, blistering, skin peeling, and swelling.

  14. Governing the global commons with local institutions. (United States)

    Bodnar, Todd; Salathé, Marcel


    Most problems faced by modern human society have two characteristics in common--they are tragedy-of-the-commons type of problems, and they are global problems. Tragedy-of-the-commons type of problems are those where a commonly shared resource is overexploited by free riders at the expense of everyone sharing the resource. The exploitation of global resources such as clean air and water, political stability and peace, etc. underlies many of the most pressing human problems. Punishment of free riding behavior is one of the most frequently used strategies to combat the problem, but the spatial reach of sanctioning institutions is often more limited than the spatial effects of overexploitation. Here, we analyze a general game theoretical model to assess under what circumstances sanctioning institutions with limited reach can maintain the larger commons. We find that the effect of the spatial reach has a strong effect on whether and how the commons can be maintained, and that the transitions between those outcomes are characterized by phase transitions. The latter indicates that a small change in the reach of sanctioning systems can profoundly change the way the global commons can be managed.

  15. Ecology and the Tragedy of the Commons

    Directory of Open Access Journals (Sweden)

    Peter Roopnarine


    Full Text Available This paper develops mathematical models of the tragedy of the commons analogous to ecological models of resource consumption. Tragedies differ fundamentally from predator–prey relationships in nature because human consumers of a resource are rarely controlled solely by that resource. Tragedies do occur, however, at the level of the ecosystem, where multiple species interactions are involved. Human resource systems are converging rapidly toward ecosystem-type systems as the number of exploited resources increase, raising the probability of system-wide tragedies in the human world. Nevertheless, common interests exclusive of exploited commons provide feasible options for avoiding tragedy in a converged world.

    Directory of Open Access Journals (Sweden)

    David S. Murphy


    Full Text Available Accounting and marketing are very different disciplines. The analysis of customer profitability is one concept that can unite accounting and marketing as a common denominator. In this article I search for common ground between accounting and marketing in the analysis of customer profitability to determine if a common denominator really exists between the two. This analysis focuses on accounting profitability, customer lifetime value, and customer equity. The article ends with a summary of what accountants can do to move the analysis of customer value forward, as an analytical tool, within companies.

    DEFF Research Database (Denmark)

    Gerdes, Ulrik


    Apolipoprotein E (apoE) has important functions in systemic and local lipid transport, but also has other functions. The gene (APOE) shows a common polymorphism with three alleles--APOE*2, APOE*3, and APOE*4. Their frequencies vary substantially around the world, but APOE*3 is the most common...... from only 10-15% in southern Europe to 40-50% in the north. The gradient may be a trace of the demic expansion of agriculture that began about 10,000 years ago, but it may also reflect the possibility that APOE*4 carriers are less likely to develop vitamin D deficiency.

  20. Phenotyping common beans for adaptation to drought (United States)

    Beebe, Stephen E.; Rao, Idupulapati M.; Blair, Matthew W.; Acosta-Gallegos, Jorge A.


    Common beans (Phaseolus vulgaris L.) originated in the New World and are the grain legume of greatest production for direct human consumption. Common bean production is subject to frequent droughts in highland Mexico, in the Pacific coast of Central America, in northeast Brazil, and in eastern and southern Africa from Ethiopia to South Africa. This article reviews efforts to improve common bean for drought tolerance, referring to genetic diversity for drought response, the physiology of drought tolerance mechanisms, and breeding strategies. Different races of common bean respond differently to drought, with race Durango of highland Mexico being a major source of genes. Sister species of P. vulgaris likewise have unique traits, especially P. acutifolius which is well adapted to dryland conditions. Diverse sources of tolerance may have different mechanisms of plant response, implying the need for different methods of phenotyping to recognize the relevant traits. Practical considerations of field management are discussed including: trial planning; water management; and field preparation. PMID:23507928

  9. Common Cause Failure Modeling: Aerospace Versus Nuclear (United States)

    Stott, James E.; Britton, Paul; Ring, Robert W.; Hark, Frank; Hatfield, G. Spencer


    Aggregate nuclear plant failure data is used to produce generic common-cause factors that are specifically for use in the common-cause failure models of NUREG/CR-5485. Furthermore, the models presented in NUREG/CR-5485 are specifically designed to incorporate two significantly distinct assumptions about the methods of surveillance testing from whence this aggregate failure data came. What are the implications of using these NUREG generic factors to model the common-cause failures of aerospace systems? Herein, the implications of using the NUREG generic factors in the modeling of aerospace systems are investigated in detail and strong recommendations for modeling the common-cause failures of aerospace systems are given.

  11. The commons and development: unanswered sociological questions

    Directory of Open Access Journals (Sweden)

    Thomas K. Rudel


    Full Text Available Do processes of political and economic development hinder or promote the creation of common property institutions (CPIs to govern common pool resources? Despite the seeming importance of this question, development sociologists have never really tried to answer it. This paper explores the intersection of development processes, the commons, and common property institutions and concludes that development has countervailing influences that both impede and promote the formation of CPIs. Institutional expansion centered around the state facilitates the formation of CPIs while market expansion through globalization and labor migration weakens CPIs. Business cycles have similar influences. Economic booms weaken CPIs while subsequent economic downturns increase the likelihood that resource users will form CPIs.

  12. Social Justice and the Environmental Commons. (United States)

    Flanagan, Constance A; Byington, Rachel; Gallay, Erin; Sambo, Allison


    In this chapter, we build on the scholarship on youth civic engagement by turning attention to the environmental commons as a space for political action. We begin with a definition of the term and arguments about ways that social justice is implied in it. Following that, we raise several psychological challenges to motivating action on behalf of the environmental commons and discuss the critical experiences and actions that can defy those challenges. Finally, drawing from Ostrom's empirical evidence opposing a tragedy of the commons, we discuss practices consistent with a social justice approach that nurture in younger generations an identification with and commitment to the environmental commons and discuss how this orientation would benefit human beings, democracies, and the earth. © 2016 Elsevier Inc.

    In this paper, a novel type of network called network sharing common nonlinearity comprising both autonomous and non-autonomous oscillators have been investigated. We propose that these networks are robust for operating at desired modes i.e., chaotic or periodic by altering the v-i characteristics of common nonlinear element alone. The dynamics of these networks were examined through numerical, analytical, experimental and Multisim simulations.

  20. A common language for computer security incidents

    Energy Technology Data Exchange (ETDEWEB)

    John D. Howard; Thomas A Longstaff


    Much of the computer security information regularly gathered and disseminated by individuals and organizations cannot currently be combined or compared because a common language has yet to emerge in the field of computer security. A common language consists of terms and taxonomies (principles of classification) which enable the gathering, exchange and comparison of information. This paper presents the results of a project to develop such a common language for computer security incidents. This project results from cooperation between the Security and Networking Research Group at the Sandia National Laboratories, Livermore, CA, and the CERT{reg_sign} Coordination Center at Carnegie Mellon University, Pittsburgh, PA. This Common Language Project was not an effort to develop a comprehensive dictionary of terms used in the field of computer security. Instead, the authors developed a minimum set of high-level terms, along with a structure indicating their relationship (a taxonomy), which can be used to classify and understand computer security incident information. They hope these high-level terms and their structure will gain wide acceptance, be useful, and most importantly, enable the exchange and comparison of computer security incident information. They anticipate, however, that individuals and organizations will continue to use their own terms, which may be more specific both in meaning and use. They designed the common language to enable these lower-level terms to be classified within the common language structure.

  1. Identity, Commons and Sustainability: An Economic Perspective

    Directory of Open Access Journals (Sweden)

    Marco Setti


    Full Text Available Commons represent a wide, heterogeneous class of resources but its composition is the subject of growing tensions. The question “What is a commons?” has become even more complex while the answer still remains elusive. Current research focuses on two main attributes of commons—nonexclusivity and rivalry—centered on regulatory and operational aspects, conveying the notion of usability. Instead, this study argues that the definition of commons should be derived from their function. It is proposed that identity, in its individual and collective integrated dimensions, is the ultimate goal of commons. Despite the pivotal function that commons can perform, availability of resources is indeed just one of the conditions for human development. Moreover, commons can deploy their identity-oriented functions only if a sustainability transition is pursued. Based on these considerations, the study analyzes the concept of sustainability, and addresses the question “What is to be sustained?” While the capability approach offers a coherent conceptualization of the diversity of individuals—a crucial issue for sustainability—some limitations arise when it is adopted as evaluative space of well-being. This study argues that the assumed notion of identity delivers a broader concept of sustainability and delineates the ultimate goal of sustainability (sustainable identity.

  2. Commons, Piracy and the Crisis of Property

    Directory of Open Access Journals (Sweden)

    James Arvanitakis


    Full Text Available This article takes the politicisation of copyright and file sharing as a starting point to discuss the concept of the commons and the construction of property. Empirically, the article draws on a series of interviews with Pirate Party members in Sweden, Australia, Germany, the UK and USA; placed in the theoretical framework of the commons. We argue that piracy, as an act and an ideology, interrogates common understandings of property as something self-evident, natural and uncontestable. Such constructions found liberal market ideology. The article has two broad aims: to outline the different phases of enclosure, from the physical commons, to the institutional and finally the cultural commons; and to discuss the way that piracy highlights the emergent crisis in private property rights, brought to the fore by the global financial crisis and ongoing privatization of public resources. We conclude by questioning what new modes of enclosure are emerging in a digital economy driven by excessive data mining and centralized streaming services.

  3. The most common friend first immunization

    International Nuclear Information System (INIS)

    Nian Fu-Zhong; Hu Cha-Sheng


    In this paper, a standard susceptible-infected-recovered-susceptible(SIRS) epidemic model based on the Watts–Strogatz (WS) small-world network model and the Barabsi–Albert (BA) scale-free network model is established, and a new immunization scheme — “the most common friend first immunization” is proposed, in which the most common friend’s node is described as being the first immune on the second layer protection of complex networks. The propagation situations of three different immunization schemes — random immunization, high-risk immunization, and the most common friend first immunization are studied. At the same time, the dynamic behaviors are also studied on the WS small-world and the BA scale-free network. Moreover, the analytic and simulated results indicate that the immune effect of the most common friend first immunization is better than random immunization, but slightly worse than high-risk immunization. However, high-risk immunization still has some limitations. For example, it is difficult to accurately define who a direct neighbor in the life is. Compared with the traditional immunization strategies having some shortcomings, the most common friend first immunization is effective, and it is nicely consistent with the actual situation. (paper)

  4. Economic Analysis of Social Common Capital (United States)

    Uzawa, Hirofumi


    Social common capital provides members of society with those services and institutional arrangements that are crucial in maintaining human and cultural life. The term æsocial common capital' is comprised of three categories: natural capital, social infrastructure, and institutional capital. Natural capital consists of all natural environment and natural resources including the earth's atmosphere. Social infrastructure consists of roads, bridges, public transportation systems, electricity, and other public utilities. Institutional capital includes hospitals, educational institutions, judicial and police systems, public administrative services, financial and monetary institutions, and cultural capital. This book attempts to modify and extend the theoretical premises of orthodox economic theory to make them broad enough to analyze the economic implications of social common capital. It further aims to find the institutional arrangements and policy measures that will bring about the optimal state of affairs.

  6. Common post-operative complications in children

    Directory of Open Access Journals (Sweden)

    Dilip Pawar


    Full Text Available The exact incidence of common post-operative complications in children is not known. Most common one is post-operative nausea and vomiting followed by respiratory complications leading to hypoxia. Cardiac complications are less in children without associated congenital cardiac anomaly. Post-operative shivering, agitation and delirium are seen more often in children anaesthetised with newer inhalational agents like sevoflurane and desflurane. Urinary retention in the post-operative period could be influenced by anaesthetic drugs and regional blocks. The purpose of this article is to review the literature and present to the postgraduate students comprehensive information about the current understanding and practice pattern on various common complications in the post-operative period. Extensive literature was searched with key words of various complications from Pubmed, Google scholar and specific journal, namely paediatric anaesthesia. The relevant articles, review article meta-analysis and editorials were the primary source of information for this article.

  7. Themata in science and in common sense

    Directory of Open Access Journals (Sweden)

    Marková Ivana


    Full Text Available Human thinking is heterogeneous, and among its different forms, thinking in dyadic oppositions is associated with the concept of themata. Gerald Holton characterises themata as elements that lie beneath the structure and development of physical theories as well as of non-scientific thinking. Themata have different uses, such as a thematic concept, or a thematic component of the concept; a methodological (or epistemological thema; and a propositional thema. Serge Moscovici has placed the concept of themata in the heart of his theory of social representations which is based on ‘natural thinking’ and on forms of daily knowing, including common sense. In this article I shall explore some features of thematic concepts and of methodological themata in scientific theories and in common sense. More specifically, I shall refer to the significance of the methodological (or epistemological thema the Self and Other(s in common-sense thinking and in social practices.

  8. Structures for common-cause failure analysis

    International Nuclear Information System (INIS)

    Vaurio, J.K.


    Common-cause failure methodology and terminology have been reviewed and structured to provide a systematical basis for addressing and developing models and methods for quantification. The structure is based on (1) a specific set of definitions, (2) categories based on the way faults are attributable to a common cause, and (3) classes based on the time of entry and the time of elimination of the faults. The failure events are then characterized by their likelihood or frequency and the average residence time. The structure provides a basis for selecting computational models, collecting and evaluating data and assessing the importance of various failure types, and for developing effective defences against common-cause failure. The relationships of this and several other structures are described

  10. The Common Framework for Earth Observation Data (United States)

    Gallo, J.; Stryker, T. S.; Sherman, R.


    Each year, the Federal government records petabytes of data about our home planet. That massive amount of data in turn provides enormous benefits to society through weather reports, agricultural forecasts, air and water quality warnings, and countless other applications. To maximize the ease of transforming the data into useful information for research and for public services, the U.S. Group on Earth Observations released the first Common Framework for Earth Observation Data in March 2016. The Common Framework recommends practices for Federal agencies to adopt in order to improve the ability of all users to discover, access, and use Federal Earth observations data. The U.S. Government is committed to making data from civil Earth observation assets freely available to all users. Building on the Administration's commitment to promoting open data, open science, and open government, the Common Framework goes beyond removing financial barriers to data access, and attempts to minimize the technical impediments that limit data utility. While Earth observation systems typically collect data for a specific purpose, these data are often also useful in applications unforeseen during development of the systems. Managing and preserving these data with a common approach makes it easier for a wide range of users to find, evaluate, understand, and utilize the data, which in turn leads to the development of a wide range of innovative applications. The Common Framework provides Federal agencies with a recommended set of standards and practices to follow in order to achieve this goal. Federal agencies can follow these best practices as they develop new observing systems or modernize their existing collections of data. This presentation will give a brief on the context and content of the Common Framework, along with future directions for implementation and keeping its recommendations up-to-date with developing technology.

  12. Acquisition through common slave (servus communis

    Directory of Open Access Journals (Sweden)

    Bogunović Mirjana B.


    Full Text Available Common slave (servus communis is a slave who belongs to two masters. Both masters may entirely dispose with the slave because their joint ownership allows it. However, acquisitions through common slave (servus communis is not that clear. Does a slave evenly oblige co-masters or only the master on whose behalf he has acted? Is it possible for a slave to work in the interest of one master and oblige another? Who does the unconscientious slave correspond to, the third party or a betrayed master? This paper will analyze the opinions of two Roman iurists, which will partly solve doubts that this institute causes.

  13. Humanism as a common factor in psychotherapy. (United States)

    Wampold, Bruce E


    There are many forms of psychotherapies, each distinctive in its own way. From the origins of psychotherapy, it has been suggested that psychotherapy is effective through factors that are common to all therapies. In this article, I suggest that the commonalities that are at the core of psychotherapy are related to evolved human characteristics, which include (a) making sense of the world, (b) influencing through social means, and (c) connectedness, expectation, and mastery. In this way, all psychotherapies are humanistic. (c) 2012 APA, all rights reserved.

  14. Development of a Common Nordic Balance Settlement

    Energy Technology Data Exchange (ETDEWEB)



    NordREG finds it essential for the customers that a common integrated end-user electricity market is developed and that all end-users are able to take part in the Nordic market. A common Nordic balance settlement is one important part of such a change. However, attention has to be paid to the comments that a badly designed common system is worse than well-designed national systems. It is thus important that the change to a common balance settlement is so thoroughly investigated that the common system gives a basis for a well-functioning market. An important basis for such a change is an agreed vision for the process: The present different systems for balance settlement shall by the year 2010 be replaced by a common Nordic balance settlement. This means that: It will be possible for a supplier to sell to the whole Nordic market from one legal entity and using only one system for customer management and reporting. The common Nordic balance settlement will be designed in such a way that it contributes to a well functioning market. This means for example that it will be attractive even for small suppliers and some end-users to be balance responsible parties. It is feasible that the first phase is focused on those present differences that are most decisive for fulfilment of the vision. NordREG recommends that the following issues shall be discussed and agreed in co-operation between NordREG, Nordel and relevant stakeholders in the first phase: The definition shall include how the common Nordic balance settlement shall interact with the balance control and the balance regulation of the interconnected power system and the balance settlement between countries performed by the TSOs. The definition should include the cost-base for common Nordic balance settlement in relation to other system responsibility costs. The core activities of system responsibility have also been analyzed by NordREG. It is important to find a balance between inter alia the need for simplicity and the

  5. A study of common-mode failures

    International Nuclear Information System (INIS)

    Edwards, G.T.; Watson, I.A.


    The purpose of the report is to investigate problems of the identification of the common failure mode (CFM) the reliability models used and the data required for their solution, particularly with regard to automatic protection systems for nuclear reactors. The available literature which was surveyed during the study is quoted and used as a basis for the main work of the study. The type of redundancy system under consideration is initially described and the types of CFM to which these systems are prone are identified before a general definition of the term 'common mode failure' is proposed. The definition and proposed classification system for CMF are based on the common cause of failure, so identifying the primary events. Defences against CFM are included and proposals for an overall strategy and detailed recommendations for design and operation are made. Common mode failures in US nuclear reactor systems, aircraft systems, and other sources including chemical plant systems are surveyed. The data indicates the importance of the human error problem in the causes of CMF in design, maintenance and operation. From a study of the collected data a redundancy sub-system model for CMF is developed which identifies three main categories of failure, non-recurrent engineering design errors, maintenance and test errors, and random interest events. The model proposed allows for the improvement in sub-system reliability where appropriate defences are applied. (author)

  8. Building a Common Platform on Students' Participation (United States)

    Lundin, Mattias


    This article sets out to examine how school science activities can encourage students' participation while supporting a specific science content. One ordinary class with 12-year-old students was chosen and their regular classroom work was studied without intervention and with a minimum of interference. Lessons were video filmed, transcribed and analyzed focussing on the participants' speech acts. It was found that students' initiatives and experiences were important parts of their participation. The results show how students' participation was orchestrated with a science content by means of four different kinds of activities. The activities are called `individual inventory of experiences', `building a common platform of experiences', `sharing new experiences' and `concluding a common platform'. The activities form a foundation for participation in human biology topics. For example, to `build a common platform of experiences' seems to level out students' different prerequisites for participating in subsequent tasks. Furthermore, to `conclude a common platform' implied a checkpoint of the shared new experiences. The activities support students' tentative use of scientific words as well as their learning of what counts as knowledge in the school science setting. However, it can be questioned if the time spent on each separate activity is necessary or if similar achievements could be made even if some activities were integrated. The question is open for further research.

  13. Developing a Science Commons for Geosciences (United States)

    Lenhardt, W. C.; Lander, H.


    Many scientific communities, recognizing the research possibilities inherent in data sets, have created domain specific archives such as the Incorporated Research Institutions for Seismology ( and Though this is an important step forward, most scientists, including geoscientists, also use a variety of software tools and at least some amount of computation to conduct their research. While the archives make it simpler for scientists to locate the required data, provisioning disk space, compute resources, and network bandwidth can still require significant efforts. This challenge exists despite the wealth of resources available to researchers, namely lab IT resources, institutional IT resources, national compute resources (XSEDE, OSG), private clouds, public clouds, and the development of cyberinfrastructure technologies meant to facilitate use of those resources. Further tasks include obtaining and installing required tools for analysis and visualization. If the research effort is a collaboration or involves certain types of data, then the partners may well have additional non-scientific tasks such as securing the data and developing secure sharing methods for the data. These requirements motivate our investigations into the "Science Commons". This paper will present a working definition of a science commons, compare and contrast examples of existing science commons, and describe a project based at RENCI to implement a science commons for risk analytics. We will then explore what a similar tool might look like for the geosciences.

  7. Logical Normativity and Common Sense Reasoning

    Directory of Open Access Journals (Sweden)

    Evandro Agazzi


    Full Text Available Logic, considered as a technical discipline inaugurated by Aristotle and typically represented by the variety of the modern logical calculi, constitutes a clarification and refinement of a conviction and practice present in common sense, that is, the fact that humans believe that truth can be acquired not only by immediate evidence, but also by means of arguments. As a first step logic can be seen as a “descriptive” record of the main forms of the arguments present in common sense, but the fact that some of these patterns can actually allow for the derivation of false consequences from true premises imposes the task of making explicit what patterns correspond to a “correct reasoning” and what not. At this point logic (that contains the presentation of such patterns appears endowed with a “normative” characteristic. This amounts to saying that logical calculi are intended to adequately mirror the intuitive notion of “logical consequence” and in this sense they cannot be totally arbitrary or conventional, but must satisfy certain basic requirements such as the conditions of soundness and (as far as possible of semantic completeness. In such a way they are “judged” according to the fundamental requirements present at the level of common sense and appear as “idealizations” of the kinds of reasoning practiced in common sense. For this reason also several kinds of logical calculi are fully justified since they make explicit in an idealized form the concrete ways of reasoning that are imposed by the particular domain of reference of the discipline in which they are used and which are basically recognized in common sense.

  8. Ruling the Commons. Introducing a new methodology for the analysis of historical commons

    Directory of Open Access Journals (Sweden)

    Tine de Moor


    Full Text Available Despite significant progress in recent years, the evolution of commons over the long run remains an under-explored area within commons studies. During the last years an international team of historians have worked under the umbrella of the Common Rules Project in order to design and test a new methodology aimed at advancing our knowledge on the dynamics of institutions for collective action – in particular commons. This project aims to contribute to the current debate on commons on three different fronts. Theoretically, it explicitly draws our attention to issues of change and adaptation in the commons – contrasting with more static analyses. Empirically, it highlights the value of historical records as a rich source of information for longitudinal analysis of the functioning of commons. Methodologically, it develops a systematic way of analyzing and comparing commons’ regulations across regions and time, setting a number of variables that have been defined on the basis of the “most common denominators” in commons regulation across countries and time periods. In this paper we introduce the project, describe our sources and methodology, and present the preliminary results of our analysis.

    Full Text Available This paper explores how commons reproduce over time and introduces the concept of commoning to discuss rural continuities and change. The point of departure is that commons are essential for local community development in that they have an important role for mediating social change and for local identity production. Through an ethnographic and historical study of a number of commons systems from the village of Ängersjö in the Midwest of Sweden, the paper argues for a more historically and socially grounded understanding of how commons evolve. The paper examines Ängersjö’s commons within two broad historical time frames – the pre-industrial (4th to 20th century and the post-industrial time periods (20th century to the present – in order to understand commons, not just as arenas for resource extraction and resource struggles, but also as important contexts for identity formation, local mobilisation and for shaping rural change. The paper reveals how the commons have co-evolved with changes in society at large and how the meanings and functions of the commons have changed throughout history – from being important economic resources – to cultural and symbolic resources that have created new avenues for collective action.

  10. Shoulder Ultrasonography: Performance and Common Findings

    Directory of Open Access Journals (Sweden)

    Diana Gaitini


    Full Text Available Ultrasound (US of the shoulder is the most commonly requested examination in musculoskeletal US diagnosis. Sports injuries and degenerative and inflammatory processes are the main sources of shoulder pain and functional limitations. Because of its availability, low cost, dynamic examination process, absence of radiation exposure, and ease of patient compliance, US is the preferred mode for shoulder imaging over other, more sophisticated, and expensive methods. Operator dependence is the main disadvantage of US examinations. Use of high range equipment with high resolution transducers, adhering to a strict examination protocol, good knowledge of normal anatomy and pathological processes and an awareness of common pitfalls are essential for the optimal performance and interpretation of shoulder US. This article addresses examination techniques, the normal sonographic appearance of tendons, bursae and joints, and the main pathological conditions found in shoulder ultrasonography.

  11. Optimum operating regimes of common paramagnetic refrigerants

    CERN Document Server

    Wikus, P; Figueroa-Feliciano, E


    Adiabatic Demagnetization Refrigerators (ADRs) are commonly used in cryogenic laboratories to achieve subkelvin temperatures. ADRs are also the technology of choice for several space borne instruments which make use of cryogenic microcalorimeters or bolometers {[}1-4]. For these applications, refrigerants with high ratios of cooling capacity to volume, or cooling capacity to mass are usually required. In this manuscript, two charts for the simple selection of the most suitable of several common refrigerants (CAA, CMN, CPA, DGG, FAA, GGG, GLF and MAS) are presented. These graphs are valid for single stage cycles. The selection of the refrigerants is uniquely dependent on the starting conditions of the refrigeration cycle (temperature and magnetic field density) and the desired final temperature. Only thermodynamic properties of the refrigerants have been taken into account, and other important factors such as availability and manufacturability have not been considered. (C) 2011 Elsevier Ltd.

  12. Diseases Transmitted by Less Common House Pets. (United States)

    Chomel, Bruno B


    Beside dogs and cats, the most common pets worldwide, an increasing number of pocket pets and exotic pets are making their way to more and more households, especially in North America and Europe. Although many of these animals make appropriate pets, they also can be a source of many zoonotic diseases, especially in young children and immunocompromised individuals. Some of these diseases can be life threatening, such as rabies, rat bite fever, and plague. Some others are quite common, because of the frequency of the pathogens harbored by these species, such as salmonellosis in reptiles and amphibians. Appropriate knowledge of the zoonotic agents carried by these "new" pet species is strongly recommended prior to acquiring pocket or exotic pets. Furthermore, adopting wildlife as pets is strongly discouraged, because it is always a risky action that can lead to major health issues.

  13. The Commons revisited: The tragedy continues

    International Nuclear Information System (INIS)

    Lloyd, Bob


    Garrett Hardin's classic paper 'Tragedy of the Commons' published in Science in 1968 struck a chord with scientists and non-scientists alike and has continued to provide a key reference point to how a number of 'Commons'-related problems can be viewed. Hardin's paper will be in looked at in view of both anthropogenic global warming and peak oil and some of the solutions he posed for the 'population problem' applied to the post-peak era. Possible solutions are compared with the Kyoto Protocol for global warming and the Rimini Protocol for peak oil. A carbon-indexed, universal tax on non-renewable energy resources 'Unitax' is mooted as a longer-term possibility to overcoming both global warming and the financing of post-peak oil problems. Alas, the process of dealing with global warming and peak oil seems to be falling into the 'no technical solution' category that Hardin identified for population

  14. Common Shoulder Injuries in American Football Athletes. (United States)

    Gibbs, Daniel B; Lynch, T Sean; Nuber, Erika D; Nuber, Gordon W


    American football is a collision sport played by athletes at high speeds. Despite the padding and conditioning in these athletes, the shoulder is a vulnerable joint, and injuries to the shoulder girdle are common at all levels of competitive football. Some of the most common injuries in these athletes include anterior and posterior glenohumeral instability, acromioclavicular pathology (including separation, osteolysis, and osteoarthritis), rotator cuff pathology (including contusions, partial thickness, and full thickness tears), and pectoralis major and minor tears. In this article, we will review the epidemiology and clinical and radiographic workup of these injuries. We also will evaluate the effectiveness of surgical and nonsurgical management specifically related to high school, collegiate, and professional football athletes.

  15. Multiple cranial neuropathy: a common diagnostic problem. (United States)

    Garg, R K; Karak, B


    Syndrome of multiple cranial palsies is a common clinical problem routinely encountered in neurological practice. Anatomical patterns of cranial nerves involvement help in localizing the lesion. Various infections, malignant neoplasms and autoimmune vasculitis are common disorders leading to various syndromes of multiple cranial nerve palsies. A large number of diffuse neurological disorders (e.g. Gullian-Barre syndrome, myopathies) may also present with syndrome of multiple cranial nerve palsies. Despite extensive biochemical and radiological work-up the accurate diagnosis may not be established. Few such patients represent "idiopathic" variety of multiple cranial nerve involvement and show good response to corticosteroids. Widespread and sequential involvements of cranial nerves frequently suggest possibility of malignant infiltration of meninges, however, confirmation of diagnosis may not be possible before autopsy.

  16. Common Preposition Errors Committed by Iranian Students

    Directory of Open Access Journals (Sweden)

    Samaneh Yousefi


    Full Text Available This paper examined some common problems involving prepositions in learning a second language. Many students learning English as a foreign language commonly commit mistakes in prepositions. The aim of this paper is to survey the causes of errors in the use of prepositions that are frequently made by Iranian students. A diagnostic test (35 Multiple choice item was constructed to test the students proficiency in using these prepositions. The prepositions selected for this purpose were; to, in, at, on, with, of, from, for, about, during, into under, over and by. This test was given to a group of 35 intermediate students. The results indicated that the errors committed by the students were due to both Inter-lingual and Intra-lingual interferences. It is hoped that this research will help teachers of English Language to be aware of these problems and re-evaluate their teaching approach.

  17. Genetics in psychiatry: common variant association studies

    Buxbaum Joseph D


    Full Text Available Abstract Many psychiatric conditions and traits are associated with significant heritability. Genetic risk for psychiatric conditions encompass rare variants, identified due to major effect, as well as common variants, the latter analyzed by association analyses. We review guidelines for common variant association analyses, undertaking after assessing evidence of heritability. We highlight the importance of: suitably large sample sizes; an experimental design that controls for ancestry; careful data cleaning; correction for multiple testing; small P values for positive findings; assessment of effect size for positive findings; and, inclusion of an independent replication sample. We also note the importance of a critical discussion of any prior findings, biological follow-up where possible, and a means of accessing the raw data.

    A retrospective study on computed tomographic (CT) findings in 35 surgically confirmed cases of common bile duct stones was performed to analyze the characteristic CT findings. Choledocholithiasis was correctly diagnosed by CT in 33 out of 35 cases (sensitivity, 94.3%) and among these CT demonstrated calculi of high attenuation in 32 and of soft tissue density in one case. The thirty two included 23 totally calcified. 5 rim calcified and 4 laminated stones. The target sign was observed in 30 out of 33 CT positive cases (90.1%). We concluded that CT is an accurate modality in the diagnosis of common bile duct stones with its' reliable display of the calcified or the laminated stone itself and its' characteristic target sign.

    as of access to help. Fundamentally these are questions concerning the nature of health promotion, ethnicity, gender and empowerment. The above mentioned research project facilitated our understanding of such questions. It did so because it took its point of departure in the women’s own perspectives......In 2003 a research project on the personal and common meanings of sexualised coercion was initiated at the Centre for Victims of Sexual Assault at the University Hospital of Copenhagen. Right from its start in the year 2000 first and second generation migrant women were among those seeking help...... at the Centre. This raised questions as to whether sexualised coercion has special meanings for migrant women in their trajectories across different communities, or whether the meanings of sexualised coercion are common/universal. It also raises questions of risks of being exposed to sexualised coercion as well...

  1. Headings for an EEC common energy policy

    International Nuclear Information System (INIS)

    Bailey, R.


    Although self-sufficiency in energy supplies during the 1980s may make a purely national UK energy policy look attractive, the author argues that it is in the long-term interest of all nine community members if policy is coordinated on an EEC scale. Any possible common energy policy would probably consist of separate policies for coal, oil, natural gas and nuclear power. It would follow the same general principles as the Common Agricultural Policy in maximising production of coal, natural gas and nuclear power but oil would be covered by negotiating with OPEC for current supplies and treating indigenous supplies as a strategic reserve, with Community finance available for development of marginal fields.

  2. The Case for Common Reference Intervals (United States)

    Jones, Graham RD; Barker, Antony; Tate, Jill; Lim, Chen-Fee; Robertson, Ken


    The current paradigm for pathology reference intervals is for each laboratory to determine its own interval for use with each test offered by the laboratory. It is our contention that this approach does not best serve the medical community, especially at a time when electronic databases of health information are being expanded and integrated. We also believe that this approach is not performed well in many laboratories and is excessively expensive in practice. In contrast, we believe that the preferable option is to develop and apply common reference intervals throughout Australia and New Zealand, together with common reporting formats and assay standardisation wherever this is possible. We are aware that these are neither trivial nor simple issues, however we believe that failure to achieve this goal where technically possible will be a failure of the pathology profession to meet the challenges of the modern health community.

  3. Michel Lepeletier and the common education

    Directory of Open Access Journals (Sweden)



    Full Text Available This work contains the analyses of the National Education Plan drawn up by Michel Lepeletier and presented to the Convention by Robespierre on Julay 13th, 1793, seeking to place it within the educational coordinates of the French Revolution. Its most characteristic feature was the proposal of the creation of institutions where all children would receive a common education on a full-board basis, paid for by the Republic. Lepeletier's proposals gave rise to an intense discussion amongst deputies such as Grégoire, Bourdon, Lequino, Fourcroy and Thibaudeau, as well as Robespierre and Danton. The ideas producing the greatest polemic were: the obligatory nature of common education, its financing, the confinement of children in «houses of equality » and the Spartan inspiration behind the projet.

    Full Text Available In Hungary a huge part of wooden plants are shrubs. Flora of hungarian forests is among the richest in Europe. Many plants can be classified as shrubs or trees as well, circumstances during their development define what they will become. The diverse world of shrubs and weeds delights the eye under 20-30 meter high trees. From these there are some well known which basically everybody recognises is lilac (Syringa vulgaris, elderberry (Sambucus nigra, dog-rose (Rosa canina, single-seeded hawthorn (Crataegus monogyna and common buckthorn (Rhamnus cathartica. To get these species better known – and occasionally foreshadowing their wood industry usage in some way – it is expendient to familiarize ourselves with their microscopic structure and characteristics. Nowadays there are several imaging methods known, however for examining floral tissue the optical microscope is still the most common one to be used.

  6. Control of common symptoms in advanced cancer. (United States)

    Fallon, M T; Hanks, G W


    In common with any medical problem, careful assessment and an analytical approach are the keystones to effective symptom control in advanced cancer. When dealing with such symptoms the multi-faceted pathophysiology must be considered, and due attention paid to the affective component of pain and other symptoms. Adequate care given to history taking and a knowledge of the likely pathogenesis of symptoms in advanced cancer can prevent unnecessary investigations and fruitless trials of inappropriate symptomatic remedies. The treatment chosen should be the simplest effective regimen tailored to the individual patient. The importance of explanation to the patient cannot be overstated and is an integral part of any treatment and the sole component of many. This paper reviews the management of common symptoms in advanced cancer (dyspnoea, nausea and vomiting, constipation, anorexia-cachexia syndrome, hypercalcaemia, confusion, insomnia and depression.

  7. Common Errors in Ecological Data Sharing

    Directory of Open Access Journals (Sweden)

    Robert B. Cook


    Full Text Available Objectives: (1 to identify common errors in data organization and metadata completeness that would preclude a “reader” from being able to interpret and re-use the data for a new purpose; and (2 to develop a set of best practices derived from these common errors that would guide researchers in creating more usable data products that could be readily shared, interpreted, and used.Methods: We used directed qualitative content analysis to assess and categorize data and metadata errors identified by peer reviewers of data papers published in the Ecological Society of America’s (ESA Ecological Archives. Descriptive statistics provided the relative frequency of the errors identified during the peer review process.Results: There were seven overarching error categories: Collection & Organization, Assure, Description, Preserve, Discover, Integrate, and Analyze/Visualize. These categories represent errors researchers regularly make at each stage of the Data Life Cycle. Collection & Organization and Description errors were some of the most common errors, both of which occurred in over 90% of the papers.Conclusions: Publishing data for sharing and reuse is error prone, and each stage of the Data Life Cycle presents opportunities for mistakes. The most common errors occurred when the researcher did not provide adequate metadata to enable others to interpret and potentially re-use the data. Fortunately, there are ways to minimize these mistakes through carefully recording all details about study context, data collection, QA/ QC, and analytical procedures from the beginning of a research project and then including this descriptive information in the metadata.

    Svein Jentoft; Paul Onyango; Mohammad Mahmudul Islam


    Abstract In fisheries, alleviating poverty sometimes requires strategies that are inherently in conflict. When aiming to develop a fishery as a means to reduce poverty, its common pool resource basis might be undermined, resulting in greater poverty. But poverty in fisheries is also linked to, or a part of deeper social issues and processes, for instance, the marginalization and exclusion of certain communities. Poverty also has many factors— income, health, literacy, gender, power, sec...

    Obesity has become an important public health problem worldwide that disproportionally affects the underserved. Obesity has been associated with many diseases and unfortunately has not spared the respiratory system. Specifically, the prevalence of common respiratory problems, such as asthma and obstructive sleep apnoea, is higher in obese children. Further, the treatment outcomes of these frequent conditions is also worse in obese children compared to lean controls. Copyright © 2016 Elsevier Ltd. All rights reserved.

  18. Network geometry inference using common neighbors (United States)

    Papadopoulos, Fragkiskos; Aldecoa, Rodrigo; Krioukov, Dmitri


    We introduce and explore a method for inferring hidden geometric coordinates of nodes in complex networks based on the number of common neighbors between the nodes. We compare this approach to the HyperMap method, which is based only on the connections (and disconnections) between the nodes, i.e., on the links that the nodes have (or do not have). We find that for high degree nodes, the common-neighbors approach yields a more accurate inference than the link-based method, unless heuristic periodic adjustments (or "correction steps") are used in the latter. The common-neighbors approach is computationally intensive, requiring O (t4) running time to map a network of t nodes, versus O (t3) in the link-based method. But we also develop a hybrid method with O (t3) running time, which combines the common-neighbors and link-based approaches, and we explore a heuristic that reduces its running time further to O (t2) , without significant reduction in the mapping accuracy. We apply this method to the autonomous systems (ASs) Internet, and we reveal how soft communities of ASs evolve over time in the similarity space. We further demonstrate the method's predictive power by forecasting future links between ASs. Taken altogether, our results advance our understanding of how to efficiently and accurately map real networks to their latent geometric spaces, which is an important necessary step toward understanding the laws that govern the dynamics of nodes in these spaces, and the fine-grained dynamics of network connections.

  19. Commons of Identity: Sherpa Identity Management

    Directory of Open Access Journals (Sweden)

    Leif Rune Loland


    Full Text Available The recent history of Sherpas demonstrates how identities can be scarce goods. While ‘Sherpa’ refers to an ethnic identity, ‘Sherpa’ refers to a crucial occupation in the trekking industry.i Their privileged position in Nepal’s international tourist industry is related to their common reputation. Their collective use of identity seems to help them getting access to an economic niche, and work in tourism seems to be an aspect of being Sherpa. Thus, an individual that operates in the tourist market does not only manage material assets but also identity assets to maintain the Sherpa reputation. Consequently, one can expect it to be a collective concern to husband their image, ie to control each member’s behaviour which could affect the Sherpa image. This article on Sherpa identity in encounters with outsiders analyses Sherpaness as a manageable resource that constitutes a collectively sanctioned commons. My point of departure is Barth’s analysis of ethnic boundary dynamics (1969, 1994 combined with Bourdieu’s concept of ‘capital’ and Hardin’s perspective on commons.DOI: 10.3126/dsaj.v1i0.288Dhaulagiri Vol.1 (2005 pp.176-192

  20. Bald eagle predation on common loon egg (United States)

    DeStefano, Stephen; McCarthy, Kyle P.; Laskowski, Tom


    The Common Loon (Gavia immer) must defend against many potential egg predators during incubation, including corvids, Herring Gulls (Larus argentatus), raccoons (Procyon lotor), striped skunk (Mephitis mephitis), fisher (Martes pennanti), and mink (Neovison vison) (McIntyre 1988, Evers 2004, McCann et al. 2005). Bald Eagles (Haliaeetus leucocephalus) have been documented as predators of both adult Common Loons and their chicks (Vliestra and Paruk 1997, Paruk et al. 1999, Erlandson et al. 2007, Piper et al. 2008). In Wisconsin, where nesting Bald Eagles are abundant (>1200 nesting pairs, >1 young/pair/year), field biologists observed four instances of eagle predation of eggs in loon nests during the period 2002–2004 (M. Meyer pers. comm.). In addition, four cases of eagle predation of incubating adult loons were inferred from evidence found at the loon nest (dozens of plucked adult loon feathers, no carcass remains) and/or loon leg, neck, and skull bones beneath two active eagle nests, including leg bones containing the bands of the nearby (adult loon. However, although loon egg predation has been associated with Bald Eagles, predation events have yet to be described in peer-reviewed literature. Here we describe a photographic observation of predation on a Common Loon egg by an immature Bald Eagle as captured by a nest surveillance video camera on Lake Umbagog, a large lake (32 km2) at Umbagog National Wildlife Refuge (UNWR) in Maine.

  1. Information-Theoretic Inference of Common Ancestors

    Directory of Open Access Journals (Sweden)

    Bastian Steudel


    Full Text Available A directed acyclic graph (DAG partially represents the conditional independence structure among observations of a system if the local Markov condition holds, that is if every variable is independent of its non-descendants given its parents. In general, there is a whole class of DAGs that represents a given set of conditional independence relations. We are interested in properties of this class that can be derived from observations of a subsystem only. To this end, we prove an information-theoretic inequality that allows for the inference of common ancestors of observed parts in any DAG representing some unknown larger system. More explicitly, we show that a large amount of dependence in terms of mutual information among the observations implies the existence of a common ancestor that distributes this information. Within the causal interpretation of DAGs, our result can be seen as a quantitative extension of Reichenbach’s principle of common cause to more than two variables. Our conclusions are valid also for non-probabilistic observations, such as binary strings, since we state the proof for an axiomatized notion of “mutual information” that includes the stochastic as well as the algorithmic version.

  2. Common pass decentered annular ring resonator

    Energy Technology Data Exchange (ETDEWEB)

    Holmes, D. A.; Waite, T. R.


    An optical resonator having an annular cylindrical gain region for use in a chemical laser or the like in which two ring-shaped mirrors having substantially conical reflecting surfaces are spaced apart along a common axis of revolution of the respective conical surfaces. A central conical mirror reflects incident light directed along said axis radially outwardly to the reflecting surface of a first one of the ring-shaped mirrors. The radial light rays are reflected by the first ring mirror to the second ring mirror within an annular cylindrical volume concentric with said common axis and forming a gain region. Light rays impinging on the second ring mirror are reflected to diametrically opposite points on the same conical mirror surfaces and back to the first ring mirror through the same annular cylindrical volume. The return rays are then reflected by the conical mirror surface of the first ring mirror back to the central conical mirror. The mirror surfaces are angled such that the return rays are reflected back along the common axis by the central mirror in a concentric annular cylindrical volume. A scraper mirror having a central opening centered on said axis and an offset opening reflects all but the rays passing through the two openings in an output beam. The rays passing through the second opening are reflected back through the first opening to provide feedback.

  3. Autoimmune cytopenias related to common variable immunodeficiency

    Directory of Open Access Journals (Sweden)

    Vlasta Petric


    Full Text Available Background: Common variable immunodeficiency disorders are characterised by defective antibody production leading to recurrent infections. Noninfective complications are a consequence of autoimmunity, granuloma and polyclonal lymphoid infiltration. We often detect autoimmune cytopenias before primary immunodefciency is confirmed. Patients and methods: We report a case of 39-year old man with recurrent respiratory infections, autoimmune thrombocytopenia and haemolytic anemia who had common varible immunodeficiency confirmed. He had a lack of serum IgG, IgA and IgM, bronchiectasis, lymphadenopathy, splenomegaly, hepatic granuloma, autoimmune gastritis with B12 deficiency and Evans syndrome. We treated autoimmune cytopenias with methylprednisolon and cyclosporine. After substitution therapy with intravenous immunoglobulin the frequency of espiratory infections decreased. Occurrence of diarrhea is suspected for enteropathy, however, hystologic identification is required. Because of patologically changed gastric mucosa and signs of polyclonal lymphoid infiltration, the patient is at high risk for malignancy and the outcome of the disease remains unpredictable. Conclusions: Generally, we discover common variable immunodeficiency at management of noninfective complications, in wich intravenous immunoglobulin are not effective. Autoimmune cytopenias and some other complications are successfully treated with glucocorticoids. Careful monitorig of these patients is important because of a high risk for malignancy.

  4. Genes and (common pathways underlying drug addiction.

    Directory of Open Access Journals (Sweden)

    Chuan-Yun Li


    Full Text Available Drug addiction is a serious worldwide problem with strong genetic and environmental influences. Different technologies have revealed a variety of genes and pathways underlying addiction; however, each individual technology can be biased and incomplete. We integrated 2,343 items of evidence from peer-reviewed publications between 1976 and 2006 linking genes and chromosome regions to addiction by single-gene strategies, microrray, proteomics, or genetic studies. We identified 1,500 human addiction-related genes and developed KARG (, the first molecular database for addiction-related genes with extensive annotations and a friendly Web interface. We then performed a meta-analysis of 396 genes that were supported by two or more independent items of evidence to identify 18 molecular pathways that were statistically significantly enriched, covering both upstream signaling events and downstream effects. Five molecular pathways significantly enriched for all four different types of addictive drugs were identified as common pathways which may underlie shared rewarding and addictive actions, including two new ones, GnRH signaling pathway and gap junction. We connected the common pathways into a hypothetical common molecular network for addiction. We observed that fast and slow positive feedback loops were interlinked through CAMKII, which may provide clues to explain some of the irreversible features of addiction.

    Maximum common substructure search is a computationally hard optimization problem with diverse applications in the field of cheminformatics, including similarity search, lead optimization, molecule alignment, and clustering. Most of these applications have strict constraints on running time, so heuristic methods are often preferred. However, the development of an algorithm that is both fast enough and accurate enough for most practical purposes is still a challenge. Moreover, in some applications, the quality of a common substructure depends not only on its size but also on various topological features of the one-to-one atom correspondence it defines. Two state-of-the-art heuristic algorithms for finding maximum common substructures have been implemented at ChemAxon Ltd., and effective heuristics have been developed to improve both their efficiency and the relevance of the atom mappings they provide. The implementations have been thoroughly evaluated and compared with existing solutions (KCOMBU and Indigo). The heuristics have been found to greatly improve the performance and applicability of the algorithms. The purpose of this paper is to introduce the applied methods and present the experimental results.

  6. Evaluation of common organisms causing vaginal discharge. (United States)

    Khan, Shazia A; Amir, Fauzia; Altaf, Shagufta; Tanveer, Raazia


    Vaginal discharge is very common problem among females. Alteration in balance of normal vaginal organisms can cause the overgrowth of the bacteria that creates vaginal discharge. It is common among sexually active women yet there still remain gaps in our knowledge of this infectious disorder. To evaluate the frequency of bacterial vaginosis (BV), vaginal candidiasis (VC), vaginal trichomoniasis and Group B streptococcus in women complaining of vaginal discharge in our setup. A total of 100 women of reproductive age group with the complaint of vaginal discharge were included in the study. After filling proforma patients were examined by speculum examination and two high vaginal swabs (HVS) were collected aseptically from each patient. One swab was used for making wet mount for clue cells, pus cells and for motility of Trichomonas vaginalis. The other swab was used to check pH and Amine test. The growth was confirmed by Gram staining in each case. Gardnerrella vaginalis were isolated in 28%, Group B streptococcus in 5% and T. vaginolis in 4% of women. Gardnerella vaginalis causing BV is the most common cause of vaginal discharge in otherwise healthy women of reproductive age group in our setup.

    Common variable immunodeficiency (CVID) is the most common adult-onset primary antibody deficiency disease due to various causative genes. Several genes, which are known to be the cause of different diseases, have recently been reported as the cause of CVID in patients by performing whole exome sequencing (WES) analysis. Here, we found FANC gene mutations as a cause of adult-onset CVID in two patients. B cells were absent and CD4 + T cells were skewed toward CD45RO + memory T cells. T-cell receptor excision circles (TRECs) and signal joint kappa-deleting recombination excision circles (sjKRECs) were undetectable in both patients. Both patients had no anemia, neutropenia, or thrombocytopenia. Using WES, we identified compound heterozygous mutations of FANCE in one patient and homozygous mutation of FANCA in another patient. The impaired function of FANC protein complex was confirmed by a monoubiquitination assay and by chromosome fragility test. We then performed several immunological evaluations including quantitative lymphocyte analysis and TRECs/sjKRECs analysis for 32 individuals with Fanconi anemia (FA). In total, 22 FA patients (68.8%) were found to have immunological abnormalities, suggesting that such immunological findings may be common in FA patients. These data indicate that FANC mutations are involved in impaired lymphogenesis probably by the accumulation of DNA replication stress, leading to CVID. It is important to diagnose FA because it drastically changes clinical management. We propose that FANC mutations can cause isolated immunodeficiency in addition to bone marrow failure and malignancy.

  8. Common patterns in 558 diagnostic radiology errors. (United States)

    Donald, Jennifer J; Barnard, Stuart A


    As a Quality Improvement initiative our department has held regular discrepancy meetings since 2003. We performed a retrospective analysis of the cases presented and identified the most common pattern of error. A total of 558 cases were referred for discussion over 92 months, and errors were classified as perceptual or interpretative. The most common patterns of error for each imaging modality were analysed, and the misses were scored by consensus as subtle or non-subtle. Of 558 diagnostic errors, 447 (80%) were perceptual and 111 (20%) were interpretative errors. Plain radiography and computed tomography (CT) scans were the most frequent imaging modalities accounting for 246 (44%) and 241 (43%) of the total number of errors, respectively. In the plain radiography group 120 (49%) of the errors occurred in chest X-ray reports with perceptual miss of a lung nodule occurring in 40% of this subgroup. In the axial and appendicular skeleton missed fractures occurred most frequently, and metastatic bone disease was overlooked in 12 of 50 plain X-rays of the pelvis or spine. The majority of errors within the CT group were in reports of body scans with the commonest perceptual errors identified including 16 missed significant bone lesions, 14 cases of thromboembolic disease and 14 gastrointestinal tumours. Of the 558 errors, 312 (56%) were considered subtle and 246 (44%) non-subtle. Diagnostic errors are not uncommon and are most frequently perceptual in nature. Identification of the most common patterns of error has the potential to improve the quality of reporting by improving the search behaviour of radiologists. © 2012 The Authors.

    Ergemen, Yunus Emre; Taamouti, Abderrahim

    A parametric portfolio policy function is considered that incorporates common stock volatility dynamics to optimally determine portfolio weights. Reducing dimension of the traditional portfolio selection problem significantly, only a number of policy parameters corresponding to first- and second......-order characteristics are estimated based on a standard method-of-moments technique. The method, allowing for the calculation of portfolio weight and return statistics, is illustrated with an empirical application to 30 U.S. industries to study the economic activity before and after the recent financial crisis....

    Rausch, R.; Serre, Ch.


    The PS and SPS Accelerator Control Systems are becoming obsolete and need urgent rejuvenation. After a control users forum, where users expressed their needs, two main Working Groups were set up, consisting of Control and Equipment Specialists and experienced Machine Operators. One Working Group studied the architecture and the front-end processing and the other a common approach to the application software needed to run the CERN accelerator complex. The paper presents the technical conclusion of their work and the policy to implement it, taking into account the necessity to operate both machines without interruption of the Physics Program.

  12. Common Variable Immunodeficiency and Gastric Malignancies. (United States)

    Leone, Patrizia; Vacca, Angelo; Dammacco, Franco; Racanelli, Vito


    Common variable immunodeficiency (CVID) is an immunodeficiency disorder with a high incidence of gastrointestinal manifestations and an increased risk of gastric carcinoma and lymphoma. This review discusses the latest advancements into the immunological, clinical and diagnostic aspects of gastric malignancies in patients with CVID. The exact molecular pathways underlying the relationships between CVID and gastric malignancies remain poorly understood. These include genetics, immune dysregulation and chronic infections by Helicobacter pylori . Further studies are needed to better stratify the risk for cancer in these patients, to elaborate surveillance programs aimed at preventing these complications, and to develop new and more effective therapeutic approaches.

  15. Standard deviation of the longest common subsequence


    Lember, Jüri; Matzinger, Heinrich


    Let Ln be the length of the longest common subsequence of two independent i.i.d. sequences of Bernoulli variables of length n. We prove that the order of the standard deviation of Ln is $\\sqrt{n}$ , provided the parameter of the Bernoulli variables is small enough. This validates Waterman’s conjecture in this situation [Philos. Trans. R. Soc. Lond. Ser. B 344 (1994) 383–390]. The order conjectured by Chvatal and Sankoff [J. Appl. Probab. 12 (1975) 306–315], however, is different.

    The paper proposes a refinement of the concept of 'Common Information Spaces' (CIS), which has been proposed as a conceptual framework for the CWCW field in order to provide analyses of cooperative work. The refinement is developed through an introductory discussion of previous analyses of CIS...... and on the basis of a thorough description of the CIS of a hospital ward based on ethnographic fieldwork. The initially definition is refined by the introduction of 7 parameters: (i) the degree of distribution of work; (ii) the multiplicity of webs of significance; (iii) the level of required articulation work...

  17. Common Variable Immunodeficiency: Diagnosis, Management, and Treatment. (United States)

    Abbott, Jordan K; Gelfand, Erwin W


    Common variable immunodeficiency (CVID) refers to a grouping of antibody deficiencies that lack a more specific genetic or phenotypic classification. It is the immunodeficiency classification with the greatest number of constituents, likely because of the numerous ways in which antibody production can be impaired and the frequency in which antibody production becomes impaired in human beings. CVID comprises a heterogeneous group of rare diseases. Consequently, CVID presents a significant challenge for researchers and clinicians. Despite these difficulties, both our understanding of and ability to manage this grouping of complex immune diseases has advanced significantly over the past 60 years. Copyright © 2015 Elsevier Inc.

  19. Auditory verbal hallucinations in schizophrenia and post-traumatic stress disorder: common phenomenology, common cause, common interventions?

    Directory of Open Access Journals (Sweden)

    Simon eMccarthy-Jones


    Full Text Available Auditory verbal hallucinations (AVH: ‘hearing voices’ are found in both schizophrenia and post-traumatic stress disorder (PTSD. In this paper we first demonstrate that AVH in these two diagnoses share a qualitatively similar phenomenology. We then show that the presence of AVH in schizophrenia is often associated with earlier exposure to traumatic/emotionally overwhelming events, as it is by definition in PTSD. We next argue that the content of AVH relates to earlier traumatic events in a similar way in both PTSD and schizophrenia, most commonly having direct or indirect thematic links to emotionally overwhelming events, rather than being direct re-experiencing. We then propose, following cognitive models of PTSD, that the reconstructive nature of memory may be able to account for the nature of these associations between trauma and AVH content, as may threat-hypervigilance and the individual’s personal goals. We conclude that a notable subset of people diagnosed with schizophrenia with AVH are having phenomenologically and aetiologically identical experiences to PTSD patients who hear voices. As such we propose that the iron curtain between AVH in PTSD (often termed ‘dissociative AVH’ and AVH in schizophrenia (so-called ‘psychotic AVH’ needs to be torn down, as these are often the same experience. One implication of this is that these trauma-related AVH require a common trans-diagnostic treatment strategy. Whilst antipsychotics are already increasingly being used to treat AVH in PTSD, we argue for the centrality of trauma-based interventions for trauma-based AVH in both PTSD and in people diagnosed with schizophrenia.

  1. Common Running Overuse Injuries and Prevention

    Directory of Open Access Journals (Sweden)

    Žiga Kozinc


    Full Text Available Runners are particularly prone to developing overuse injuries. The most common running-related injuries include medial tibial stress syndrome, Achilles tendinopathy, plantar fasciitis, patellar tendinopathy, iliotibial band syndrome, tibial stress fractures, and patellofemoral pain syndrome. Two of the most significant risk factors appear to be injury history and weekly distance. Several trials have successfully identified biomechanical risk factors for specific injuries, with increased ground reaction forces, excessive foot pronation, hip internal rotation and hip adduction during stance phase being mentioned most often. However, evidence on interventions for lowering injury risk is limited, especially regarding exercise-based interventions. Biofeedback training for lowering ground reaction forces is one of the few methods proven to be effective. It seems that the best way to approach running injury prevention is through individualized treatment. Each athlete should be assessed separately and scanned for risk factors, which should be then addressed with specific exercises. This review provides an overview of most common running-related injuries, with a particular focus on risk factors, and emphasizes the problems encountered in preventing running-related injuries.

  2. Renewable and nuclear power: A common future?

    International Nuclear Information System (INIS)

    Verbruggen, Aviel


    Nuclear power and renewable energy are the main options to bring down the carbon intensity of commercial energy supply. What technology is unlimited backstop supply depends on its performance on the sustainability criteria: democratic decided, globally accessible, environmental benign, low risk, affordable. Renewable power meets all criteria, with affordability under debate. Maximizing energy efficiency as prerequisite, the affordable sustainable option in fact is the twin efficiency/renewable power. Nuclear power falls short on the sustainability criteria and its public acceptance is low. Nuclear proponents now propose nuclear and renewable energy as a suitable couple to address the climate change challenge. The two antagonists however are mutually exclusive on the five major directions of future power systems. First, nuclear power has been architect of the expansive 'business-as-usual' energy economy since the 1950s. Second, add-on by fossil-fuelled power plants is bulky and expansive for nuclear power, but is distributed, flexible and contracting over time for renewable power. Third, power grids for spreading bulky nuclear outputs are other than the interconnection between millions of distributed power sources requires. Fourth, risks and externalities and the proper technology itself of nuclear power limit its development perspectives, while efficiency/renewable power are still in their infancy. Fifth, their stalemate for R and D resources and for production capacities will intensify. Nuclear power and renewable power have no common future in safeguarding 'Our Common Future'

    Idrees, M.; Khan, S.; Riazuddin, S.


    Objective: To find out the frequency of common genotypes of hepatitis-B virus (HBV). Subjects and Methods: HBV genotypes were determined in 112 HBV DNA positive sera by a simple and precise molecular genotyping system base on PCR using type-specific primers for the determination of genotypes of HBV A through H. Results: Four genotypes (A,B,C and D) out of total eight reported genotypes so far were identified. Genotypes A, B and C were predominant. HBV genotype C was the most predominant in this collection, appearing in 46 samples (41.7%). However, the genotypes of a total of 5 (4.46%) samples could not be determined with the present genotyping system. Mixed genotypes were seen in 8(7.14% HBV) isolates. Five of these were infected with genotypes A/D whereas two were with genotypes C/D. One patient was infected with 4 genotypes (A/B/C/D). Genotype A (68%) was predominant in Sindh genotype C was most predominant in North West Frontier Province (NWFP) (68.96) whereas genotype C and B were dominant in Punjab (39.65% and 25.86% respectively). Conclusion: All the four common genotypes of HBV found worldwide (A,B,C and D) were isolated. Genotype C is the predominant Genotypes B and C are predominant in Punjab and N.W.F.P. whereas genotype A is predominant in Sindh. (author)

  4. Common Spatialities: The Production of the Multitude

    Directory of Open Access Journals (Sweden)

    Lucía Jalón Oyrazún


    Full Text Available The Gezi Park barricades in Istanbul, the OWS occupation of Zucotti Park in New York City, the tents of the Indignados movement in Spain, the London Blackberry riots and the seizure of Tahrir Square in Cairo to demand the overthrow of a dictator. As new forms of social coexistence and relationships are being configured, and new spaces for encounter and conflict are produced, architecture feels that essential questions regarding its activity are being addressed in each and every one of these situations. And yet we seem unable to relate to them and grasp their significance as we repeatedly turn to old metaphors and tools. If modern architecture pursues the modern liberal state techniques of management and administration of life, then recent forms of political action, which claim a new relation to the sensible, demand – and might help develop – a new understanding of architecture. We are moving from technical and disciplinary knowledge towards a critical practice that integrates with the action of the multitude. Starting from a definition of commons as the production of the multitude, we seek not only to understand the spatial dimension of this production, but also to acknowledge space as common

  5. Active agents in common skin care products. (United States)

    Draelos, Zoe Diana


    Skin care products are numerous and perplexing, yet the majority fall into the moisturizer category. Moisturizers are substances designed to improve and maintain the skin barrier. They serve as a vehicle for the delivery of active ingredients that minimize facial lines of dehydration, deliver photoprotection, and provide antioxidant properties. Moisturizers are based on occlusive substances, such as petrolatum and dimethicone, and humectant substances, such as glycerin, with a variety of sunscreens and botanicals for added functionality and marketing impact. This article reviews these common active agents. The plethora of over-the-counter skin care products available for patient purchase is overwhelming, yet there is certain commonality among 80 percent of the formulations. The majority of the products are moisturizers with added ingredients to support marketing claims. Whether the product is a facial foundation, an antiaging night cream, a sunscreen, a topical antioxidant, or a skin-lightening serum, the formulation is basically a moisturizer. Sunscreen is the most biologically active antiaging ingredient in skin care products, but the antiinflammatory and antioxidant effects of botanicals possess tremendous marketing appeal.

  6. Canada: variations on a common theme

    Directory of Open Access Journals (Sweden)

    Raisa B. Deber


    Full Text Available Canada faces health care challenges common to all industrialized countries – how to ensure timely access to high quality care, close to home, at an affordable cost. Addressing these challenges is complicated by interjurisdictional variation in both how health care is managed and delivered, and in health outcomes. Canada can be described as a non-system of 10 provincial and three territorial health insurance plans which mandate publicly-funded coverage for medically necessary hospital and physician services, based upon common principles and shaped by a federal governance structure that affords substantial power and autonomy to the provinces/territories over matters of health and health care. This article first examines the structural context of the health care system in Canada, including the range of services publicly funded, the public-private mix, and the complexities of current governance arrangements. It then discusses several issues affecting health policy reform: costs versus access; questions of sustainability, quality, and performance; human resources capacity; and the provision of public and population health services.

  7. Yukon's common oil and gas regime

    International Nuclear Information System (INIS)

    Love, B.


    The Yukon's common oil and gas regime was developed in partnership with First Nations and it sets out the rules that will apply throughout the Yukon and on Yukon and First Nation lands. While separate and distinct, it conforms with and is compatible with other government systems and regimes. The major elements of the common regime include the Oil and Gas Act, regulations, policies, processes and agreements. The specific opportunities that are available in each phase of oil and gas development in the Yukon are described, with a map showing all basins, reserves and sites of current oil and gas activity. The Yukon has eight potential oil and gas basins: North Coast, Old Crow, Kandik, Eagle Plain, Peel Plateau, Bonnet Plume, Whitehorse Trough, and Liard Plateau. Only three of the eight, the Liard Plateau, Whitehorse Trough and Eagle Plain, have been explored. No wells have been drilled in several of Yukon's basins. Factors influencing economic opportunities in the Territory are also described, including: (1) international events and energy markets, (2) North American gas markets, (3) environmental factors, (4) competitiveness of the Yukon regime, and (5) the commitment of industry resources. 4 figs

  8. Women's knowledge of commonly used contraceptive methods. (United States)

    Schrager, Sarina; Hoffmann, Sarah


    Despite the availability of reliable contraceptive methods in this country, half of all pregnancies are unintended. There is a scarcity of research in a primary care population that measures women's knowledge about commonly used contraceptive methods. All women between 18 and 40 in the waiting room at 2 different family practice clinics were approached over a 2-week period. Women were asked to complete a short written questionnaire that included demographics, reproductive information, and 9 true/false questions about common contraceptive methods. Two hundred fifty-two surveys were completed. Half of all women believed that condoms are 99% effective and only 57% knew that condoms were not as effective as oral contraceptive pills. Close to half of all the women received their contraceptive information from the clinic. Only 42% of the women knew that oral contraceptive pills can reduce the incidence of some types of cancer. There was not correlation between number of questions answered correctly and number of children, type of contraceptive used, age, or race/ethnicity. Twenty-six percent of the respondents were not using any contraception. Overall, the women surveyed demonstrated fairly good knowledge of contraception methods. More women surveyed were aware that oral contraceptive pills can reduce the rate of uterine and ovarian cancer than in previous similar studies. Also, women in this survey were more likely to use intrauterine devices than the general population. Health care professionals should develop more effective education about contraceptive methods.

  9. Watershed Management: Lessons from Common Property Theory

    Directory of Open Access Journals (Sweden)

    John Kerr


    Full Text Available Watershed development is an important component of rural development and natural resource management strategies in many countries. A watershed is a special kind of common pool resource: an area defined by hydrological linkages where optimal management requires coordinated use of natural resources by all users. Management is difficult because natural resources comprising the watershed system have multiple, conflicting uses, so any given management approach will spread benefits and costs unevenly among users. To address these challenges, watershed approaches have evolved from more technocratic to a greater focus on social organization and participation. However, the latter cannot necessarily be widely replicated. In addition, participatory approaches have worked better at a small scale, but hydrological relationships cover a larger scale and some projects have faced tradeoffs in choosing between the two. Optimal approaches for future efforts are not clear, and theories from common property research do not support the idea that complex watershed management can succeed everywhere. Solutions may include simplifying watershed projects, pursuing watershed projects where conditions are favorable, and making other investments elsewhere, including building the organizational capacity that can facilitate watershed management.

  10. USGEO Common Framework For Earth Observation Data (United States)

    Walter, J.; de la Beaujardiere, J.; Bristol, S.


    The United States Group on Earth Observations (USGEO) Data Management Working Group (DMWG) is an interagency body established by the White House Office of Science and Technology Policy (OSTP). The primary purpose of this group is to foster interagency cooperation and collaboration for improving the life cycle data management practices and interoperability of federally held earth observation data consistent with White House documents including the National Strategy for Civil Earth Observations, the National Plan for Civil Earth Observations, and the May 2013 Executive Order on Open Data (M-13-13). The members of the USGEO DMWG are working on developing a Common Framework for Earth Observation Data that consists of recommended standards and approaches for realizing these goals as well as improving the discoverability, accessibility, and usability of federally held earth observation data. These recommendations will also guide work being performed under the Big Earth Data Initiative (BEDI). This talk will summarize the Common Framework, the philosophy behind it, and next steps forward.

  11. Iranian Common Attitude Toward Opium Consumption (United States)

    Zarghami, Mehran


    Iran is suffering from the 2nd most severe addiction to opioids in the world. While the explanation of this enormous drug problem is refutably related to drug trafficking, the drug dilemma also illustrates the chain reaction of the imposed war with Iraq in 1980 - 88; the problems of poverty, unemployment, urbanization, homelessness, adultery, family crises, divorce, domestic violence, and runaway children. Although opium addiction often linked to these factors, drug use is common among all social classes. It seems that a positive traditional attitude is another reason for widespread raw opium use in this country. A survey in Iranian literature reveals that famous Iranian poets, who have a substantial contribution on cultural attitude formation of Iranian population, have used the phrase “Teriac” (raw opium) as a means of “antidote” a substance that treats every disease. It seems that a concrete deduction from the literature has been leaden to a positive attitude towards opium consumption in Persian culture. Recent research also supports this idea. Many patients use raw opium as a pain killer or for treating hyperlipidemia, hypertension, diabetes and other chronic diseases; most of them had started the use after developing the disease and the remaining had increased the consumption after developing the disease. Regarding this superstitious common belief, drug control headquarters should focus on education and correction of the faulty unhealthy attitude toward opium consumption. PMID:26288642

  13. Common diseases as determinants of menopausal age. (United States)

    Li, Jingmei; Eriksson, Mikael; Czene, Kamila; Hall, Per; Rodriguez-Wallberg, Kenny A


    Can the diagnosis of common diseases before menopause influence age at natural menopause (ANM) onset? Polycystic ovary syndrome (PCOS) and depression were observed to delay menopause. It has been observed that women who undergo early menopause experience a higher burden of health problems related to metabolic syndromes, heart disease and depression, but whether ANM can be influenced by common adult diseases has not been studied extensively. All women attending mammography screening or clinical mammography at four hospitals in Sweden were invited to participate in the Karolinska Mammography Project for Risk Prediction of Breast Cancer (KARMA) study. Between January 2011 and March 2013, 70 877 women were recruited. Information from the baseline questionnaire filled out upon enrollment was used in this cross-sectional analysis on predictors of ANM onset. We limited our analyses to 61 936 women with complete data on ANM and covariates and a follow-up time (from birth to menopause or censoring) of at least 35 years. Premenopausal diagnoses of depression, anorexia, bulimia, PCOS, ovarian cyst, heart failure, myocardial infarction, angina pectoris, stroke, preeclampsia, diabetes, hypertension and hyperlipidemia were examined as time-dependent variables in multivariable Cox regression analyses, adjusting for reproductive factors (age at menarche, menstrual cycle regularity in adult life, number of children and premenopausal oral contraceptive use) and risk factors of common diseases (education, physical activity at 18 years and information at the time of questionnaire including BMI, ever smoking and alcohol consumption). Women with PCOS and depression were independently associated with later menopause (hazard ratio (95% CI): 0.44 (0.28-0.71) and 0.95 (0.91-1.00), respectively), compared to women with no such histories. The associations remained significant in a subset of women who had never received gynecological surgery or hormone treatment (n = 32313, 0.21 (0

  14. Lightning attachment process to common buildings (United States)

    Saba, M. M. F.; Paiva, A. R.; Schumann, C.; Ferro, M. A. S.; Naccarato, K. P.; Silva, J. C. O.; Siqueira, F. V. C.; Custódio, D. M.


    The physical mechanism of lightning attachment to grounded structures is one of the most important issues in lightning physics research, and it is the basis for the design of the lightning protection systems. Most of what is known about the attachment process comes from leader propagation models that are mostly based on laboratory observations of long electrical discharges or from observations of lightning attachment to tall structures. In this paper we use high-speed videos to analyze the attachment process of downward lightning flashes to an ordinary residential building. For the first time, we present characteristics of the attachment process to common structures that are present in almost every city (in this case, two buildings under 60 m in São Paulo City, Brazil). Parameters like striking distance and connecting leaders speed, largely used in lightning attachment models and in lightning protection standards, are revealed in this work.Plain Language SummarySince the time of Benjamin Franklin, no one has ever recorded high-speed video images of a lightning connection to a common building. It is very difficult to do it. Cameras need to be very close to the structure chosen to be observed, and long observation time is required to register one lightning strike to that particular structure. Models and theories used to determine the zone of protection of a lightning rod have been developed, but they all suffer from the lack of field data. The submitted manuscript provides results from high-speed video observations of lightning attachment to low buildings that are commonly found in almost every populated area around the world. The proximity of the camera and the high frame rate allowed us to see interesting details that will improve the understanding of the attachment process and, consequently, the models and theories used by lightning protection standards. This paper also presents spectacular images and videos of lightning flashes connecting lightning rods that

  15. Common pediatric and adolescent skin conditions. (United States)

    Sanfilippo, Angela M; Barrio, Victoria; Kulp-Shorten, Carol; Callen, Jeffrey P


    Skin lesions are encountered in all areas of medicine, and it is therefore important for physicians to understand the fundamentals of explaining and diagnosing common skin conditions. This article begins with a discussion of description and documentation of skin lesions based on color, size, morphology, and distribution. Pigmentation disorders such as vitiligo are depicted. Cutaneous growths that are found in the pediatric and adolescent population include acrochordons, dermatofibromas, keloids, milia, neurofibromas, and pyogenic granulomas. Treatment of these growths usually involves observation or curettage with electrodessication.Psoriasis, atopic dermatitis, poison ivy, and eczema are comprised of scaling patches and plaques; poison ivy and atopic dermatitis may also present with bullous and vesicular changes. Therapy typically consists of topical emollients and corticosteroids; phototherapy is reserved for refractory cases. Acne vulgaris is the most common skin disease of the pediatric and adolescent population. This condition can be psychologically debilitating and, therefore, proper treatment is of paramount importance. Therapeutic options include topical as well as oral antibiotics and retinoids. Extreme caution must be used when prescribing retinoids to post-pubescent females, as these agents are teratogenic. Vascular anomalies are most commonly exemplified as port wine stains and hemangiomas. Port wine stains may be treated with pulsed dye laser or may be observed if they are not of concern to the patient or physician. Hemangiomas typically spontaneously regress by age ten; however, there has been recent concern that certain cases may need to be treated. Dermal rashes may be localized or generalized. Treatment of generalized drug eruptions involves elimination of the inciting agent, topical antipruritics, and systemic corticosteroids for severe reactions. Infectious etiologic agents of skin disease include bacteria, fungi, and viruses. Many sexually

    Colaco, W.; Martinez, C.R.


    A preliminary experiment was conducted to evaluate the radiosensitivity of common bean (Phaseolous vulgaris L.), cultivar to gamma rays from a 60 Co source. Sets of seeds (60 seed/sample) irradiated with 50, 100, 150, 200, and 250 Gy, were compared to a control without irradiation (0 Gy), under greenhouse conditions. The radiosensitivity was evaluated through seedling height reduction, determined at 15 days after emergence (DAE), and also through seedling survival, root length, and dry matter production of leaves, shoots and roots. Seedling height was significantly reduced for the treatments with 150 and 250 Gy, in relation to the control. The dose causing reduction of 50% seedling height was between 150 and 200 Gy. Survival rates corresponding to these doses, were, respectively, 85% and 60%. Root length and dry matter of leaves, shoots and roots, were inversely related to the doses.

  17. Cellular antioxidant activity of common vegetables. (United States)

    Song, Wei; Derito, Christopher M; Liu, M Keshu; He, Xiangjiu; Dong, Mei; Liu, Rui Hai


    The measurement of antioxidant activity using biologically relevant assays is important to screen fruits, vegetables, natural products, and dietary supplements for potential health benefits. The cellular antioxidant activity (CAA) assay quantifies antioxidant activity using a cell culture model and was developed to meet the need for a more biologically representative method than the popular chemistry antioxidant capacity measures. The objective of the study was to determine the CAA, total phenolic contents, and oxygen radical absorbance capacity (ORAC) values of 27 vegetables commonly consumed in the United States. Beets, broccoli, and red pepper had the highest CAA values, whereas cucumber had the lowest. CAA values were significantly correlated to total phenolic content. Potatoes were found to be the largest contributors of vegetable phenolics and CAA to the American diet. Increased fruit and vegetable consumption is an effective strategy to increase antioxidant intake and decrease oxidative stress and may lead to reduced risk of developing chronic diseases, such as cancer and cardiovascular disease.

  18. Common paediatric conditions of the lower limb. (United States)

    Dobbe, Ashlee M; Gibbons, Paul J


    Growing children are susceptible to a number of disorders to their lower extremities of varying degrees of severity. The diagnosis and management of these conditions can be challenging. With musculoskeletal symptoms being one of the leading reasons for visits to general practitioners, a working knowledge of the basics of these disorders can help in the appropriate diagnosis, treatment, counselling, and specialist referral. This review covers common disorders affecting the hip, the knee and the foot. The aim is to assist general practitioners in recognising developmental norms and differentiating physiological from pathological conditions and to identify when a specialist referral is necessary. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

  19. The GPM Common Calibrated Brightness Temperature Product (United States)

    Stout, J.; Chou, J.


    The Global Precipitation Measurement (GPM) project will provide a core satellite carrying the GPM Microwave Imager (GMI) and will use microwave observations from a constellation of other satellites. Each partner with a satellite in the constellation will have a calibration that meets their own requirements and will decide on the format to archive their brightness temperature (Tb) record in GPM. However, GPM multi-sensor precipitation algorithms need to input intercalibrated Tb's in order to avoid differences among sensors introducing artifacts into the longer term climate record of precipitation. The GPM Common Calibrated Brightness Temperature Product is intended to address this problem by providing intercalibrated Tb data, called "Tc" data, where the "c" stands for common. The precipitation algorithms require a Tc file format that is both generic and flexible enough to accommodate the different passive microwave instruments. The format provides detailed information on the processing history in order to allow future researchers to have a record of what was done. The format is simple, including the main items of scan time, latitude, longitude, incidence angle, sun glint angle, and Tc. It also provides a quality flag, spacecraft orientation, spacecraft location, orbit, and instrument scan type (cross-track or conical). Another simplification is to store data in real numbers, avoiding the ambiguity of scaled data. Finally, units and descriptions will be provided in the product. The format is built on the concept of a swath, which is a series of scans that have common geolocation and common scan geometry. Scan geometry includes pixels per scan, sensor orientation, scan type, and incidence angles. The format includes 3 space saving methods: first rounding variables written as floats to their needed accuracy to achieve good compression, second writing sun glint angle as a one byte variable, and third storing only unique incidence angles but allowing access via a mapping

  1. Extracting Parallel Paragraphs from Common Crawl

    Directory of Open Access Journals (Sweden)

    Kúdela Jakub


    Full Text Available Most of the current methods for mining parallel texts from the web assume that web pages of web sites share same structure across languages. We believe that there still exists a non-negligible amount of parallel data spread across sources not satisfying this assumption. We propose an approach based on a combination of bivec (a bilingual extension of word2vec and locality-sensitive hashing which allows us to efficiently identify pairs of parallel segments located anywhere on pages of a given web domain, regardless their structure. We validate our method on realigning segments from a large parallel corpus. Another experiment with real-world data provided by Common Crawl Foundation confirms that our solution scales to hundreds of terabytes large set of web-crawled data.

  2. Assay of brines for common radiolysis products

    International Nuclear Information System (INIS)

    MacDougall, C.S.


    Brines are assayed for four common products of radiolytic reaction. Free chlorine is determined spectrophotometrically after reaction with o-tolidine. The test is specific for chlorine, and quantities of chlorine from 0.1 to 6 μg in the test aliquot are determined with a precision of about +- 5%. Hydrogen peroxide is reacted with xylenol orange and determined spectrophotometrically with a precision of +- 5% on 2-μg quantities of peroxide. A spectrophotometric method using thiocyanate is employed in the chlorate assay. After subtracting the bias caused by any H 2 O 2 or Cl 2 , 1-μg quantities of chlorate can be determined with a precision of +- 10%. Perchlorate ion quantities of 1 ppM can be determined directly in brines by ion chromatography with a precision of about +- 15%

  3. Property rights, genes, and common good. (United States)

    Reed, Esther D


    This paper applies aspects of Hugo Grotius's theologically informed theory of property to contemporary issues concerning access to the human DNA sequence and patenting practices. It argues that Christians who contribute to public debate in these areas might beneficially employ some of the concepts with which he worked--notably "common right," the "right of necessity," and "use right." In the seventeenth century, wars were fought over trading rights and access to the sea. In the twenty-first century, information and intellectual property are the issues of the day. Grotius's writings serve to correct the overemphasis in modern liberalism on individual rights, and have practical application to the debate concerning the reduction of the human genome to the status of private property.

  5. Common Elements in Operational Events across Technologies

    International Nuclear Information System (INIS)

    Bley, Dennis C.; Wreathall, John; Cooper, Susan E.


    The ATHEANA project, sponsored by the US NRC, began as a study of operational events during low power and shutdown conditions at US commercial nuclear power plants. The purpose was to develop an approach for human reliability analysis that is supported by the experience; i.e., with the history of operational events. As the analysis of operational events progressed, a multidisciplinary framework evolved that can structure the analysis, highlighting significant aspects of each event. The ATHEANA multidisciplinary framework has been used as the basis for retrospective analysis of human performance in operational events in the nuclear power, chemical process, aviation, and medical technologies. The results of these analyses are exemplified by three operational events from different industries. Attention is drawn to those common elements in serious operational events that have negative impacts on human performance. (authors)

  6. Converter topologies for common mode voltage reduction (United States)

    Rodriguez, Fernando


    An inverter includes a three-winding transformer, a DC-AC inverter electrically coupled to the first winding of the transformer, a cycloconverter electrically coupled to the second winding of the transformer, and an active filter electrically coupled to the third winding of the transformer. The DC-AC inverter is adapted to convert the input DC waveform to an AC waveform delivered to the transformer at the first winding. The cycloconverter is adapted to convert an AC waveform received at the second winding of the transformer to the output AC waveform having a grid frequency of the AC grid. The active filter is adapted to sink and source power with one or more energy storage devices based on a mismatch in power between the DC source and the AC grid. At least two of the DC-AC inverter, the cycloconverter, or the active filter are electrically coupled via a common reference electrical interconnect.

  7. Common origin of visible and dark universe

    International Nuclear Information System (INIS)

    Gu Peihong; Sarkar, Utpal


    Dark matter, baryonic matter, and dark energy have different properties but contribute comparable energy density to the present Universe. We point out that they may have a common origin. As the dark energy has a scale far lower than all known scales in particle physics but very close to neutrino masses, while the excess matter over antimatter in the baryonic sector is probably related to the neutrino-mass generation, we unify the origin of the dark and visible universe in a variant of the seesaw model. In our model (i) the dark matter relic density is a dark matter asymmetry emerged simultaneously with the baryon asymmetry from leptogenesis; (ii) the dark energy is due to a pseudo-Nambu-Goldstone-Boson associated with the neutrino-mass generation.

  8. CMLOG: A common message logging system

    International Nuclear Information System (INIS)

    Chen, J.; Akers, W.; Bickley, M.; Wu, D.; Watson, W. III


    The Common Message Logging (CMLOG) system is an object-oriented and distributed system that not only allows applications and systems to log data (messages) of any type into a centralized database but also lets applications view incoming messages in real-time or retrieve stored data from the database according to selection rules. It consists of a concurrent Unix server that handles incoming logging or searching messages, a Motif browser that can view incoming messages in real-time or display stored data in the database, a client daemon that buffers and sends logging messages to the server, and libraries that can be used by applications to send data to or retrieve data from the database via the server. This paper presents the design and implementation of the CMLOG system meanwhile it will also address the issue of integration of CMLOG into existing control systems.

  9. Artery Agenesis: Ipsilateral Common Carotid Artery Hypoplasia

    Directory of Open Access Journals (Sweden)

    Omer Kaya


    Full Text Available A 42-year-old female patient, who had been diagnosed with an occlusion of her left internal carotid artery (ICA following Doppler ultrasonographic (US and digitally-subtracted angiographic (DSA examinations performed in an outer healthcare center in order to eliminate the underlying cause of her complaint of amorosis fugax, later applied to our hospital with the same complaint. At Doppler US performed in our hospital’s radiology department, her right common carotid artery (CCA was normal, but her left CCA was hypoplastic. The right internal artery (ICA was validated as normal. At the left side, however, the ICA was apparent only as a stump and it did not demonstrate a continuity. The diagnosis of ICA agenesis was confirmed by the utilization of Doppler US, CT, and DSA imaging, and it was concluded also that ipsilateral CCA hypoplasia could be evaluated as an important clue to the diagnosis of ICA agenesis.

  12. Common variable immunodeficiency in a horse. (United States)

    Flaminio, M Julia B F; LaCombe, Veronique; Kohn, Catherine W; Antczak, Douglas F


    A 12-year-old Quarter Horse mare that was nonresponsive to medical treatment was evaluated for chronic respiratory disease and hepatobiliary disease. Serum immunoglobulin concentrations were measured by use of radial immunodiffusion that revealed trace to nondetectable concentrations of IgG, IgG(T), IgM, and IgA. Use of serum protein electrophoresis confirmed agammaglobulinemia by the absence of the expected peak in the gamma region. In addition, vaccination with tetanus toxoid did not result in specific immunoglobulin production. Flow cytometric analysis of blood lymphocyte subpopulations revealed the absence of B cells in blood. Immunohistochemical analysis of tissue sections revealed the absence of B lymphocytes in bone marrow and spleen, with occasional B cells in the peripheral lymph nodes. Blood lymphocyte proliferation assays revealed weak responses to pokeweed mitogen and no response to stimulation with lipopolysaccharide. Considering the age and sex of the horse, results of the immunologic tests suggested a diagnosis of common variable immunodeficiency.

  13. Natriuretic peptides in common valvular heart disease. (United States)

    Steadman, Christopher D; Ray, Simon; Ng, Leong L; McCann, Gerry P


    Valvular heart disease, particularly aortic stenosis and mitral regurgitation, accounts for a large proportion of cardiology practice, and their prevalence is predicted to increase. Management of the asymptomatic patient remains controversial. Biomarkers have been shown to have utility in the management of cardiovascular disease such as heart failure and acute coronary syndromes. In this state-of-the-art review, we examine the current evidence relating to natriuretic peptides as potential biomarkers in aortic stenosis and mitral regurgitation. The natriuretic peptides correlate with measures of disease severity and symptomatic status and also can be used to predict outcome. This review shows that natriuretic peptides have much promise as biomarkers in common valvular heart disease, but the impact of their measurement on clinical practice and outcomes needs to be further assessed in prospective studies before routine clinical use becomes a reality.

  15. Common postural defects among music students. (United States)

    Blanco-Piñeiro, Patricia; Díaz-Pereira, M Pino; Martínez, Aurora


    Postural quality during musical performance affects both musculoskeletal health and the quality of the performance. In this study we examined the posture of 100 students at a Higher Conservatory of Music in Spain. By analysing video tapes and photographs of the students while performing, a panel of experts extracted values of 11 variables reflecting aspects of overall postural quality or the postural quality of various parts of the body. The most common postural defects were identified, together with the situations in which they occur. It is concluded that most students incur in unphysiological postures during performance. It is hoped that use of the results of this study will help correct these errors. Copyright © 2015 Elsevier Ltd. All rights reserved.

  16. Towards Common Balkan Lexical Evidential Markers

    Directory of Open Access Journals (Sweden)

    Maxim M. Makartsev


    1 As for the grammatical evidential markers in the Balkan languages, there is a tradition of their analysis dating back to the second half of the 19th century for Albanian and Bulgarian. Comparative analysis of evidential forms in the Balkan languages conducted by Victor Friedman [Friedman 1982, 1986, 1999], Grace Fielder [Fielder 1994, 1996, 1997, 1998, 1999], and several other linguists, has answered some questions about what is common among Balkan languages and what is unique for each of them in the domain of grammaticalised evidentiality. There is a great deal of literature on grammatical evidentiality in general and it is scarcely possible to cite it all within a single article, but a recent study [Aikhenvald 2004] contains the main bibliography on the issue.

  18. Remedies for common family ailments: 9. Haemorrhoids. (United States)

    Sinclair, A


    Haemorrhoids or piles are varicosities in the anal canal caused by local pressure. Sometimes they prolapse. Symptoms may include itching, discomfort, pain and bleeding. Haemorrhoids are common in pregnancy. Constipation aggravates piles, so a healthy diet with plenty of water and fibre is advisable. Some sufferers need an appropriate laxative as well. Cleanliness of the anal area is important. Proprietary moist toilet tissues are sold for this purpose and can be soothing and helpful. Relief of symptoms is by haemorrhoid creams, ointments and suppositories. Active ingredients typically include antiseptics, anti-inflammatories, anti-pruritics and local anaesthetics. Many are available from pharmacies without a prescription. If in doubt, always refer the patient to a doctor. For example, rectal bleeding may be due to some more serious condition, or pruritus to anal thrush. In the case of children the advice of a doctor should be sought.

    Directory of Open Access Journals (Sweden)

    Nikolić Ljubica


    Full Text Available Buying stocks is a modern way of investing. The investors may place the available capital on the domestic and foreign stock market, they may buy more stocks of a single issuer or distribute money to purchase stocks of various public (stock-exchange companies, and they may form a portfolio of various securities. The investors' decisions on these options are based on their estimate on returns and risks underlying individual security instruments (securities. The two basic approaches to valuation of common stocks are: the Present Value Approach (method of valuating the capitalization of income and the P/E Ratio Approach (the method of valuating the multiple of per-share earnings. Instead of viewing these methods as competing alternatives, they should better be viewed as mutually complementary methods. Both methods are equally useful and their concurrent use may provide better grounds for the analysts' valuation of stocks.

  20. Offstage: madness, the obscene, and common sense

    Directory of Open Access Journals (Sweden)

    Angel Martínez-Hernáez


    Full Text Available Throughout European history, madness has been associated with two states: movement and confinement. These apparently contradictory states converge in an obscene state, in the etymological sense of the word: offstage. In this article, based on data from ethnographic work in the Barcelona mental health care network, it is argued that "being ob-scene" results when madness challenges hegemonic social processes of inculcation and persuasion that induce acceptance of behavioral patterns considered appropriate, and lead patients to identify with the interests of therapists. Madness defies not reason, as it is widely supposed, but common sense understood as a cultural system. Its refractory nature leads to the stigmatizing management of madness in expert systems that seeks to subsume the experience of affected persons in predictable nosological categories.

  1. How Hemorrhage Control Became Common Sense. (United States)

    Hawk, Alan James


    Just over 200 years ago, surgeons were puzzled that the use of the tourniquet to control hemorrhage as common sense during surgery was a relatively recent development. Within the last 20 years, much progress has been made to controlling hemorrhage in the prehospital context. Then, as now, it was surprising that progress on something that appeared obvious had occurred only recently, begging the question how controlling blood loss was common sense in a surgical context, but not for emergency treatment. Paper is a historical survey of the evolution of the medical understanding of hemorrhage along with technological response. The danger of blood loss had historically been consistently underestimated as physicians looked at other explanations for symptoms of how the human body responded to trauma. As the danger from hemorrhage became apparent, even obvious, responsibility for hemorrhage control was delegated down from the surgeon to the paramedic and eventually to individual service members and civilian bystanders with training to "Stop the Bleed." Hippocratic medicine assumed that blood diffused centrifugally into periphery through arteries. William Harvey's observation in 1615 that blood ran through a closed circulatory system gradually transformed conventional wisdom about blood loss, leading to the development of the tourniquet about a century later by Jean-Louis Petit, which made amputation of limbs survivable. However, physicians were cautious about their application during the First World War over concerns over effects on patient recovery. Hemorrhage had generally been seen as symptom to be managed until the patient would be seen by a surgeon who would stop the bleeding. More thorough collection and analysis of data related to case histories of soldiers wounded during the Vietnam Conflict transformed how surgeons understood the importance to hemorrhage leading to development of the doctrine of Tactical Combat Casualty Care in the late 1990's. economic

  2. Common occupational classification system - revision 3

    Energy Technology Data Exchange (ETDEWEB)

    Stahlman, E.J.; Lewis, R.E.


    Workforce planning has become an increasing concern within the DOE community as the Office of Environmental Restoration and Waste Management (ER/WM or EM) seeks to consolidate and refocus its activities and the Office of Defense Programs (DP) closes production sites. Attempts to manage the growth and skills mix of the EM workforce while retaining the critical skills of the DP workforce have been difficult due to the lack of a consistent set of occupational titles and definitions across the complex. Two reasons for this difficulty may be cited. First, classification systems commonly used in industry often fail to cover in sufficient depth the unique demands of DOE`s nuclear energy and research community. Second, the government practice of contracting the operation of government facilities to the private sector has introduced numerous contractor-specific classification schemes to the DOE complex. As a result, sites/contractors report their workforce needs using unique classification systems. It becomes difficult, therefore, to roll these data up to the national level necessary to support strategic planning and analysis. The Common Occupational Classification System (COCS) is designed to overcome these workforce planning barriers. The COCS is based on earlier workforce planning activities and the input of technical, workforce planning, and human resource managers from across the DOE complex. It provides a set of mutually-exclusive occupation titles and definitions that cover the broad range of activities present in the DOE complex. The COCS is not a required record-keeping or data management guide. Neither is it intended to replace contractor/DOE-specific classification systems. Instead, the system provides a consistent, high- level, functional structure of occupations to which contractors can crosswalk (map) their job titles.

  3. Labor Dystocia: A Common Approach to Diagnosis. (United States)

    Neal, Jeremy L; Lowe, Nancy K; Schorn, Mavis N; Holley, Sharon L; Ryan, Sharon L; Buxton, Margaret; Wilson-Liverman, Angela M


    Contemporary labor and birth population norms should be the basis for evaluating labor progression and determining slow progress that may benefit from intervention. The aim of this article is to present guidelines for a common, evidence-based approach for determination of active labor onset and diagnosis of labor dystocia based on a synthesis of existing professional guidelines and relevant contemporary publications. A 3-point approach for diagnosing active labor onset and classifying labor dystocia-related labor aberrations into well-defined, mutually exclusive categories that can be used clinically and validated by researchers is proposed. The approach comprises identification of 1) an objective point that strictly defines active labor onset (point of active labor determination); 2) an objective point that identifies when labor progress becomes atypical, beyond which interventions aimed at correcting labor dystocia may be justified (point of protraction diagnosis); and 3) an objective point that identifies when interventions aimed at correcting labor dystocia, if used, can first be determined to be unsuccessful, beyond which assisted vaginal or cesarean birth may be justified (earliest point of arrest diagnosis). Widespread adoption of a common approach for diagnosing labor dystocia will facilitate consistent evaluation of labor progress, improve communications between clinicians and laboring women, indicate when intervention aimed at speeding labor progress or facilitating birth may be appropriate, and allow for more efficient translation of safe and effective management strategies into clinical practice. Correct application of the diagnosis of labor dystocia may lead to a decrease in the rate of cesarean birth, decreased health care costs, and improved health of childbearing women and neonates. © 2015 by the American College of Nurse-Midwives.

  4. Common aperture multispectral spotter camera: Spectro XR (United States)

    Petrushevsky, Vladimir; Freiman, Dov; Diamant, Idan; Giladi, Shira; Leibovich, Maor


    The Spectro XRTM is an advanced color/NIR/SWIR/MWIR 16'' payload recently developed by Elbit Systems / ELOP. The payload's primary sensor is a spotter camera with common 7'' aperture. The sensor suite includes also MWIR zoom, EO zoom, laser designator or rangefinder, laser pointer / illuminator and laser spot tracker. Rigid structure, vibration damping and 4-axes gimbals enable high level of line-of-sight stabilization. The payload's list of features include multi-target video tracker, precise boresight, strap-on IMU, embedded moving map, geodetic calculations suite, and image fusion. The paper describes main technical characteristics of the spotter camera. Visible-quality, all-metal front catadioptric telescope maintains optical performance in wide range of environmental conditions. High-efficiency coatings separate the incoming light into EO, SWIR and MWIR band channels. Both EO and SWIR bands have dual FOV and 3 spectral filters each. Several variants of focal plane array formats are supported. The common aperture design facilitates superior DRI performance in EO and SWIR, in comparison to the conventionally configured payloads. Special spectral calibration and color correction extend the effective range of color imaging. An advanced CMOS FPA and low F-number of the optics facilitate low light performance. SWIR band provides further atmospheric penetration, as well as see-spot capability at especially long ranges, due to asynchronous pulse detection. MWIR band has good sharpness in the entire field-of-view and (with full HD FPA) delivers amount of detail far exceeding one of VGA-equipped FLIRs. The Spectro XR offers level of performance typically associated with larger and heavier payloads.

  6. Iatrogenic injury to the common bile duct. (United States)

    Buturovic, Sead


    The formation of gallstones in the gall bladder is very common. It is now considered that approximately 10% to 15% of the adult population has gallstones. It is more frequent in women than men. age, sex, diet, sudden weight loss, etc. According to the report of the US National Institute of Health, it is estimated that 6.3 million men and 14.2 million women, aged 20-74 years in the United States has calculosis of the gallbladder, due to which every year is performed about 700,000 cholecystectomy. Male patient, aged about 40 years, admitted at the Clinic and laparoscopic surgery was performed in our department for chronic, as multiple, symptomatic gallbladder calculi. Intraoperative findings showed chronically inflamed, curled gall bladder, and wall thickening. After the first postoperative day there is no content in the drain bag and it is taken out, and the patient leaves the hospital without any problems. The seventh post-operative day occurred abdominal pain, weakness and fatigue, with striking yellow skin and visible mucous membranes. Clinical, laboratory and echo determined abdomen full of fluids, so it was suspected lesion of the bile duct. Urgent revision was performed. Intraoperative was found a lesion of the common bile duct in the form of a complete interruption. Created is anastomosis through transhepatic drain according to Pradera. Early and late postoperative flow was entirely normal with normal laboratory and echofindings. Control, contrast imaging through a drain showed the orderly flow of extrahepatic bile ducts, with minimal extravasation of contrast. At the Department of Surgery of General Hospital in Konjic laparoscopic cholecystectomy is performed since 1999. In the beginning it was done by three trocars (European style), and later, in order to prevent complications or injury of the bile duct is performed surgery with four trocars (American style). The number of complicated procedures in our hospital does not differ from similar indicators in

  7. Rethinking Soils: an under-investigated commons? (United States)

    Short, Chrisopher; Mills, Jane; Ingram, Julie


    In a number of global contexts there is a re-awakening of interest in soils in both increasing the resilience of complex social-ecological systems (SES) and as a result of the threats to them, as shown by the UN International Year of Soils in 2015. Consequently the management of soils and their wider role within property regimes and natural resource management might need to be reassessed. At the heart of this is the rise in awareness regarding the connectedness of SES, and in frameworks such as the Ecosystem Approach and the identification and analysis of Ecosystem Services. Whilst not new to some, it has widened the understanding among many, that soils have a valuable role to play in complex SES because they are a slow variable crucial to underlying structure of the SES. The conventional approach that soils are linked to the ecosystem services category of provisioning services (production of food, timber and fibre) remains valid. Not surprisingly this link is strong within natural resource management and property rights regimes but soils remain at risk for a range of threats, for example soil erosion and compaction, salinization, sealing, desertification, loss of organic matter and biodiversity and contamination. However, soils are increasingly seen as a slow variable that can lead to increased resilience within a SES and have a profound importance to human life through a range of regulating services including water quality and purification, water flow and attenuation and , pest and disease control. Given the long-standing importance of soil as a natural resource there are also accompanying legal systems, property regimes, societal values, knowledge, custom and traditions. However, in the light of the wider understanding soil functions are these social frameworks appropriate and fit for purpose or would a shared resource of commons approach be more appropriate. To some extent this examination would also extend to the presence of soils within the cultural services

  8. Common slavic *komońь "horse"

    Directory of Open Access Journals (Sweden)

    Loma Aleksandar


    Full Text Available The Common Slavic name for horse *koń', with a probably older, yet geographically more limited variant *komoń', has so far no generally accepted etymology. Given the great importance of this animal in the prehistory and the early history of the Indo-European and other peoples of Eurasia, this sets a problem not only for linguists, but also for historians and archeologists. The PIE word for horse, *ekuos, attested among all other branches of IE linguistic family, originally must have been common to the Slavs, as it was to their Baltic, Iranian and German neighbors, but at a later moment - which is hard to determine precisely, although we can assign it to a time before the disintegration of Slavic linguistic unity around the middle of the first millennium A. D. - for this inherited designation the new one *ko(moń' was substituted, either as a lexical innovation made by the Slavs themselves or as a borrowing from another language. Under the entries *komoń' and *koń' of the Moscow dictionary, where their continuations in Slavic languages are respectively listed, O. N. Trubachev gives a survey of previous etymological proposals and rejects all of them in favor of his own explanations. According to him, *komoń' is a Slavic onomatopoeic creation imitative of neigh, while *koń' is a loan-word, going back to Celtic *konkos/kankos 'horse' (originally 'springer'? through an intermediate form *konk', which was presumably understood as a diminutive in -'k'' and consequently shortened. Apart from the facts that the word in question is scarcely attested in comparison with two others Celtic designations for horse, *equo- (> Olr. ech, Gall, epo- and *marka-, and that in Slavic mouth it should have been reflected as *kok'', and not as *kon'k'', the very separation of both forms, *koń' and *komoń', seems unmethodical. With more reason Gamkrelidze and Ivanov recur to the old proposal connecting *koń' via *komoń' (<**kobn-? with *kobyla and further with

    Success in managing global public goods and commons is important for future welfare. Examples of global public goods include global warming, maintenance of international macroeconomic stability, international trade rules, international political stability, humanitarian assistance, and knowledge. The list is far from exhaustive. Institutions to manage international public goods include international environmental agreements such as the Kyoto Protocol, World Bank, International Monetary Fund, World Trade Organization, and United Nations. Public goods crossing national jurisdictional borders add a dimension to Samuelson's (1954) general theory for public goods. Under the current international law, obligations may be imposed only on a sovereign state with its consent. Hence, multinational institutions and international agreements often have weak or even lack of explicit control and enforcement mechanism. Compliance with agreements is often hard to control and verify, and moreover there is seldom explicit sanction mechanism in these agreements. With this in mind, it is reasonable to question whether these institutions work. In this paper the authors want to address this question by evaluating specific international environmental agreements which share many of the same characteristics as most of the institutions managing global public goods and commons. They consider the effects of voluntary international environmental protocols on emissions using the 1985 Helsinki Protocol and the 1994 Oslo Protocol on the reduction of sulfur oxides. These protocols are voluntary in the meaning that they lack control and enforcement mechanism to handle non-compliance. Lack of control and enforcement mechanism raises the question whether these voluntary protocols have an effect or that they merely tend to codify what countries would have done anwyay. The analysis utilizes panel data from 30 European countries for the period 1960-2002. The authors divided these countries into &apos

  10. Component Commonality and Its Cost Implications - Increasing the Commonality of the Right Components

    DEFF Research Database (Denmark)

    Lyly-Yrjänäinen, Jouni; Suomala, Petri; Israelsen, Poul

    Component commonality (Labro 2004, Zhou & Gruppström 2004) can be defined as the use of the same version of a component across multiple products. It is usually seen as a means to manage costs without sacrificing product variety. However, when managing costs with component commonality, the managers...... should be able to identify rather rapidly which group of components would enable the most significant cost reductions. Unfortunately, the existing literature lacks profound discussion of how to identify the right components for increased component commonality. The objective of the paper is to discuss how...... constructions was identified as the most important bottleneck for the delivery process causing many indirect costs, especially with respect to project-management-related activities. Interestingly, by eliminating the need for mechanical engineering, the context starts to approach assembly-to-order context, also...

  11. Field evaluation of two commonly used slipmeters. (United States)

    Chang, Wen-Ruey; Cotnam, John P; Matz, Simon


    A variety of slipmeters have been used to assess the slipperiness of floor surfaces. International standards for the operation of slipmeters describe the protocol for a single measurement. These standards usually do not cover some of the critical elements in safety assessment such as methods for the selection of measurement locations and the necessary number of repeated measurements at each location. Furthermore, most of the slipmeters were evaluated in laboratory settings with new floor surfaces and artificial contaminants. Two commonly used slipmeters, the Brungraber Mark II and the English XL, were evaluated at actual worksites in this experiment. Four floor tiles in each of four different work areas in the kitchens of 18 fast food restaurants were selected for repeated measurements with these two slipmeters. The results indicated that sanding of footwear materials has a significant effect on the outcomes of friction measurements, and the tile-to-tile variations in friction in the same areas of restaurants were also mostly statistically significant. Significant local variation in friction among tiles in the same area could potentially increase the chances of slip and fall incidents. Both slipmeters used in this experiment could potentially have problems in the areas with grease, such as grill and fryer areas, since the build-up of grease during repeated strikes could alter the outcome of friction measured.

  12. Brucellosis of the common vole (Microtus arvalis). (United States)

    Hubálek, Z; Scholz, H C; Sedlácek, I; Melzer, F; Sanogo, Y O; Nesvadbová, J


    A systemic disease occurred in a wild population of the common vole Microtus arvalis in South Moravia (Czech Republic) during the years 1999-2003. Acute infections were characterized by edema of extremities, occasionally with colliquating abscesses, arthritis, lymphadenitis, perforations of the skin resulting from colliquated abscesses, orchitis, and peritoneal granulomas. From the clinical samples, small Gram-negative coccobacilli were isolated and identified as Ochrobactrum intermedium by API 20NE and colistin sensitivity profiles. However, subsequent rrs (16S rRNA) and recA (recombinase A) gene sequencing analysis of two isolates (CCM 4915=CAPM 6434; CCM 4916=CAPM 6435) identified them as Brucella sp. with sequence identities of 100% to other Brucella spp. Analysis of the omp2a/b genes confirmed the two isolates as Brucella. In AMOS polymerase chain reaction (PCR), a 2000-bp fragment was generated that was not seen in other brucellae. Experimental infection of outbred ICR mice with these isolates resulted in a mortality rate of 50%. Based on the results of the molecular investigations and the mortality observed in experimentally infected mice we conclude that the epizootic was caused by Brucella sp. and not by Ochrobactrum intermedium. The study demonstrates the limitations of commercial biochemical test systems in accurately differentiating among Ochrobactrum and Brucella.

    Full Text Available Graffiti movement, born as a result of an effort of the youth, who felt themselves socially excluded and alone, to show their existence and identities during the 1960s, expanded its scope owing to street based artists such as Keith Haring and Jean-Michel Basquiat entering to the galleries, and transformed into an artistic manner of expression having aesthetic concerns by adopting a more inclusive definition ‘street art’. During this transformation of street art,street artists experimented with various methods from many different disciplines and hence created works in a wide range of varieties in terms of plastic and artistic values. Among these disciplines, printmakinghastaken its own place in street artas a discipline thatdeeply influenced street artists.Printmaking has fascinated street artists and become a part of their production process, not only with its philosophy sharing common grounds with street art and advantages in terms of its tecnical practices but also its unique plastic and linear values.Thanks to the opportunities of printmaking, street art has succeeded creating a tremendous impression worldwide, and even positioned itself into today’s greatest museums/gallery halls. This article aims to show how and in what way printmaking has influenced street art being in a transformation since the 1960s, and to put an emphasis on theimportance of printmaking on today’s street art.

  14. Optical Reflectance Measurements for Commonly Used Reflectors (United States)

    Janecek, Martin; Moses, William W.


    When simulating light collection in scintillators, modeling the angular distribution of optical light reflectance from surfaces is very important. Since light reflectance is poorly understood, either purely specular or purely diffuse reflectance is generally assumed. In this paper we measure the optical reflectance distribution for eleven commonly used reflectors. A 440 nm, output power stabilized, un-polarized laser is shone onto a reflector at a fixed angle of incidence. The reflected light's angular distribution is measured by an array of silicon photodiodes. The photodiodes are movable to cover 2pi of solid angle. The light-induced current is, through a multiplexer, read out with a digital multimeter. A LabVIEW program controls the motion of the laser and the photodiode array, the multiplexer, and the data collection. The laser can be positioned at any angle with a position accuracy of 10 arc minutes. Each photodiode subtends 6.3deg, and the photodiode array can be positioned at any angle with up to 10 arc minute angular resolution. The dynamic range for the current measurements is 10 5:1. The measured light reflectance distribution was measured to be specular for several ESR films as well as for aluminum foil, mostly diffuse for polytetrafluoroethylene (PTFE) tape and titanium dioxide paint, and neither specular nor diffuse for Lumirrorreg, Melinexreg and Tyvekreg. Instead, a more complicated light distribution was measured for these three materials.

  15. Common Misconceptions Regarding Pediatric Auditory Processing Disorder. (United States)

    Iliadou, Vasiliki; Kiese-Himmel, Christiane


    Pediatric hearing evaluation based on pure tone audiometry does not always reflect how a child hears in everyday life. This practice is inappropriate when evaluating the difficulties children experiencing auditory processing disorder (APD) in school or on the playground. Despite the marked increase in research on pediatric APD, there remains limited access to proper evaluation worldwide. This perspective article presents five common misconceptions of APD that contribute to inappropriate or limited management in children experiencing these deficits. The misconceptions discussed are (1) the disorder cannot be diagnosed due to the lack of a gold standard diagnostic test; (2) making generalizations based on profiles of children suspected of APD and not diagnosed with the disorder; (3) it is best to discard an APD diagnosis when another disorder is present; (4) arguing that the known link between auditory perception and higher cognition function precludes the validity of APD as a clinical entity; and (5) APD is not a clinical entity. These five misconceptions are described and rebutted using published data as well as critical thinking on current available knowledge on APD.

  16. Causes of mortality in common loons (United States)

    Franson, J. Christian; Cliplef, David J.


    Summarized are necropsy results from 222 carcasses of Common Loons (Gavia immer) submitted to the National Wildlife Health Research Center from 1976 through 1991.  The carcasses were from 18 states, and 10 or more birds each were from Minnesota, Florida, Virginia, Michigan, Wisconsin, Maine, and North Carolina.  Seventy-three (33%) carcasses were emaciated, and in some of these birds emaciation was thought to be related to exposure to mercury.  OVer 40% of these emaciated birds were from Florida.  Trauma, including blunt trauma of unknown origin, outboard motor propeller wounds, and shooting caused the deaths of 49 (22%) loons, 30 of which were from Minnesota.  Diseases, primarily avian botulism type E and aspergillosis, account for 39 (18%) moralities and lead poisoning for 14 (6%), 11 of which had fishing sinkers in their stomachs.  Most of the avian botulism type E cases occurred during two outbreaks on Lake Michigan.  Seven of the 14 lead-poisoned birds were from Minnesota.  Nine (4%) birds died of miscellaneous causes and 9 (4%) of drowning, primarily from entanglement in nets.  No diagnosis could be reached for 29 (13%) carcasses.  Sample bias precludes interpretation of these data to represent actual proportional causes of mortality in the loon population.  However, the sample size is sufficient to clearly identify major causes of mortality.

  17. Health-promoting properties of common herbs. (United States)

    Craig, W J


    Herbs have been used as food and for medicinal purposes for centuries. Research interest has focused on various herbs that possess hypolipidemic, antiplatelet, antitumor, or immune-stimulating properties that may be useful adjuncts in helping reduce the risk of cardiovascular disease and cancer. In different herbs, a wide variety of active phytochemicals, including the flavonoids, terpenoids, lignans, sulfides, polyphenolics, carotenoids, coumarins, saponins, plant sterols, curcumins, and phthalides have been identified. Several of these phytochemicals either inhibit nitrosation or the formation of DNA adducts or stimulate the activity of protective enzymes such as the Phase II enzyme glutathione transferase (EC Research has centered around the biochemical activity of the Allium sp. and the Labiatae, Umbelliferae, and Zingiberaceae families, as well as flaxseed, licorice root, and green tea. Many of these herbs contain potent antioxidant compounds that provide significant protection against chronic diseases. These compounds may protect LDL cholesterol from oxidation, inhibit cyclooxygenase and lipoxygenase enzymes, inhibit lipid peroxidation, or have antiviral or antitumor activity. The volatile essential oils of commonly used culinary herbs, spices, and herbal teas inhibit mevalonate synthesis and thereby suppress cholesterol synthesis and tumor growth.

  18. Aflatoxin B1 in common Egyptian foods. (United States)

    Selim, M I; Popendorf, W; Ibrahim, M S; el Sharkawy, S; el Kashory, E S


    Samples of common Egyptian foods (17 nuts and seeds, 10 spices, 31 herbs and medicinal plants, 12 dried vegetables, and 28 cereal grains) were collected from markets in Cairo and Giza. A portion of each sample was extracted with chloroform, and the concentrated extract was cleaned by passing through a silica gel column. Aflatoxin B1 was determined by reversed-phase liquid chromatography with UV detection. The highest prevalence of aflatoxin B1 was in nuts and seeds (82%), followed by spices (40%), herbs and medicinal plants (29%), dried vegetables (25%), and cereal grains (21%). The highest mean concentration of aflatoxin B1 was in herb and medicinal plants (49 ppb), followed by cereals (36 ppb), spices (25 ppb), nuts and seeds (24 ppb), and dried vegetables (20 ppb). Among nuts and seeds, the prevalence of aflatoxin B1 was highest (100%) in watermelon seeds, inshell peanuts, and unshelled peanuts. The lowest prevalence and concentrations were in hommos (garbanzo beans). The highest concentrations of aflatoxin B1 were detected in foods that had no potential for field contamination but required drying during processing and storage, such as pomegranate peel, watermelon seeds, and molokhia.

  20. Oil producers facing a common challenge

    International Nuclear Information System (INIS)

    Galal, E.E.


    Among the numerous challenges facing our modern world, perhaps the most urgent and dominant are energy related. From the perspective of developing countries they are, in order of priorities, development, energy security and environment. Oil covers above 38% of the global commercial energy needs and gas about 20%. In some commanding sectors of the economy, like transport, oil is for now virtually the irreplaceable source of energy. In addition, oil and gas are two valuable primary materials of the chemical industry. It also happens that oil consumption is one of the sources of environmental pollution through the emission of CO 2 . Utilisation of the world's finite fossil energy resources (88% of total commercial energy) in the service of development reflects all the negative attributes of the mismanagement of the global economy, exemplified by waste, inefficiency, unfair terms of trade, market instability and short-sighted policies. These serious inequities have been further compounded by the growing menace of environmental and climatic degradation. In dealing with the interactions between these three complex systems, i.e., energy, environment and development, it is important for oil producers to delineate their priorities clearly, if they are to disentangle credible common goals for an international convention.

    Full Text Available BACKGROUND The aim of the study is to determine the utility of chest sonography in common paediatric diseases and to present chest sonography images with possible explanation for the same. MATERIALS AND METHODS This retrospective study was conducted in Department of Paediatric Medicine, Bharati Medical College, Sangli. The patients admitted in paediatric ward, NICU, PICU with respiratory complaints and findings were subjected to chest sonography after chest x-ray. The chest sonography images were interpreted and an attempt was made to correlate with findings of chest xray. The information given by chest sonography was analysed and possible cause of image was evaluated. RESULTS The chest sonography appearances were found to be specific and in certain instances more informative than chest x-ray. It can differentiate between collapse and consolidation easily. The limitation of chest sonography was- it can assess only peripheral lung regions with inability to assess deeper lesions, especially with aerated peripheral lung. CONCLUSION The chest sonography is superior to chest x-ray in diagnosing minimal effusion and minimal pneumothorax. Also, when there is difficulty in differentiating pulmonary from pleural pathology. Though, chest sonography cannot replace chest x-ray, it is very useful additional investigation and often times very helpful with additional diagnostic information.

  2. Constitution and common law in bioethics. (United States)

    Santosuosso, A


    In recent years legal intervention in bioethical matters has increased notably following various paths: court decisions, parliamentary acts, codes of conduct and solemn declarations (i.e. European Bioethics Convention, 1997, or the UNESCO Genome Declaration, 1997). Body and liberty, as a question of fundamental legal rights, are constitutionalized along two paths. The former is vertical (a text created at central level is open to ratification and domestic implementation to finally become the rule in concrete cases). The latter is, above all, horizontal. It is characterized by the existence at world level of a number of centres and institutions, with the judiciary and judge-made law playing a major role. The most important new rights and freedoms in bioethics have been recognized in this ever-changing and troubled environment. The horizontal way has the great advantage of considering the differences as a resource and not as a limit. In the case law on bioethics a sort of jurisprudential model seems to be at work, that goes some way toward a judge-made law at a universal level. Cases such as Cruzan, Bland and Massimo held the fundamental concept of self-determination with surprising similarity. But we don't know if one of them has influenced the others, always supposing that the judges were aware of them. Today's first duty is to raise the consciousness of judges as to how common their problems are and how often their rulings are similar to each other's.

  3. CFOs and strategists: forging a common framework. (United States)

    Rappaport, A


    Companies have become increasingly polarized into two divergent camps: those who consider shareholder value the key to managing the company and those who put their faith in gaining competitive advantage. Indeed, that age-old debate between investing for the long term and showing outstanding short-term results is back - only this time the camps are flying banners with the new buzzwords of corporate America: competitive advantage and shareholder value. In this article, Alfred Rappaport attempts to settle the debate once and for all, arguing forcefully that establishing competitive advantage and creating shareholder value both stem from a common economic framework. In fact, long-term productivity is the hinge from which both sustainable competitive advantage and consistent results for the shareholder hang. But many managers refuse to accept this theory and cling to the mistaken belief that the market does not actually value the long-term productivity of their company but judges it only by its short-term performance. They then jump to a second mistaken conclusion: assuming they must depart from the shareholder-value model to improve their competitive position. Rappaport attacks these mistaken beliefs, showing that the stock market does value the long-term productivity of a company and that it is not necessary to depart from the shareholder-value model to improve a company's competitive position. Maximum returns for current shareholders will materialize only when managers maximize long-term shareholder value and deliver interim results that attest credibly to sustainable competitive advantage.

  4. Epidemiology of underactive bladder: Common but underresearched

    Directory of Open Access Journals (Sweden)

    Young Dong Yu


    Full Text Available Detrusor underactivity (DU or underactive bladder is a common cause of lower urinary tract symptoms (LUTS, but it is still poorly understood and underresearched. Although there has been a proposed definition by International Continence Society in 2002, no widely accepted diagnostic criteria have been established for this entity in clinical practice. Therefore, it has been rare to identify community-based researches on the epidemiology of DU until now. Only certain studies have reported the prevalence of DU in community-dwelling cohorts with significant LUTS using arbitrary urodynamic criteria for DU and these investigations have indicated that DU accounts for 25%–48% and 12%–24% of elderly men and women, respectively. However, these prevalence data based on the urodynamic definition apparently are limited in their extrapolation to the general population. Despite the clinical ambiguity of DU, its clinical effects on quality of life are quite significant, especially in the elderly population. An overall and proper comprehension of epidemiologic studies of DU may be crucial for better insight into DU, relevant decision making, and a more reasonable allocation of health resources. Therefore, researchers should find clues to the solution for the clinical diagnosis of this specific condition of LUTS from contemporary epidemiologic studies and try to develop a possible definition of ‘clinical’ DU from further studies.

    Paul Young, the British pop star who made his name in the 80s, came to visit CERN on 17 December. His son brought him here because of his passion for science in general and physics in particular. Father and son found the visit exciting and CERN’s activities really thrilling. We could even expect a surprise for Paul's next visit…   The visiting group in the CMS Control Room (Photo credit: P. Geeraert, ESO). Paul Young, famous for his interpretation of “Love of the Common People”, came to CERN because his teenage son is going to be studying A-level physics at school next year and wanted to visit the Laboratory. “I was fascinated by the visit. CERN is a place I didn’t know much about, but my son knows a lot more about science than I do. The explanations we got were great. We enjoyed the visit very much,” he said enthusiastically. Paul Young and his son visited the CMS underground cavern with Michael Hoch. &...

  6. How common is vitamin B-12 deficiency? (United States)

    Allen, Lindsay H


    In considering the vitamin B-12 fortification of flour, it is important to know who is at risk of vitamin B-12 deficiency and whether those individuals would benefit from flour fortification. This article reviews current knowledge of the prevalence and causes of vitamin B-12 deficiency and considers whether fortification would improve the status of deficient subgroups of the population. In large surveys in the United States and the United Kingdom, approximately 6% of those aged > or =60 y are vitamin B-12 deficient (plasma vitamin B-12 life. In developing countries, deficiency is much more common, starting in early life and persisting across the life span. Inadequate intake, due to low consumption of animal-source foods, is the main cause of low serum vitamin B-12 in younger adults and likely the main cause in poor populations worldwide; in most studies, serum vitamin B-12 concentration is correlated with intake of this vitamin. In older persons, food-bound cobalamin malabsorption becomes the predominant cause of deficiency, at least in part due to gastric atrophy, but it is likely that most elderly can absorb the vitamin from fortified food. Fortification of flour with vitamin B-12 is likely to improve the status of most persons with low stores of this vitamin. However, intervention studies are still needed to assess efficacy and functional benefits of increasing intake of the amounts likely to be consumed in flour, including in elderly persons with varying degrees of gastric atrophy.

  7. Freedom and poverty in the fishery commons

    Directory of Open Access Journals (Sweden)

    Svein Jentoft


    Full Text Available Abstract In fisheries, alleviating poverty sometimes requires strategies that are inherently in conflict. When aiming to develop a fishery as a means to reduce poverty, its common pool resource basis might be undermined, resulting in greater poverty. But poverty in fisheries is also linked to, or a part of deeper social issues and processes, for instance, the marginalization and exclusion of certain communities. Poverty also has many factors— income, health, literacy, gender, power, security, etc.—all of which make poverty alleviation a particularly “wicked problem” that would require a broad process of political, social and institutional reform. In other words, poverty alleviation is not only an issue of sustainable resource management but also one of societal governance. Drawing from research in small-scale fisheries communities in Nicaragua, Tanzania, and Bangladesh, this paper describes how fishing people cope with poverty. The paper discusses what the governance implications are for alleviating poverty at individual, household and community levels, and argue that both the definition of poverty and poverty alleviation in small-scale fisheries must be rooted in real life experiences.

  9. Using variable transformations to perform common event analysis

    International Nuclear Information System (INIS)

    Worrell, R.B.


    Any analytical method for studying the effect of common events on the behavior of a system is considered as being a form of common event analysis. The particular common events that are involved often represent quite different phenomena, and this has led to the development of different kinds of common event analysis. For example, common mode failure analysis, common cause analysis, critical location analysis, etc., are all different kinds of common event analysis for which the common events involved represent different phenomena. However, the problem that must be solved for each of these different kinds of common event analysis is essentially the same: Determine the effect of common events on the behavior of a system. Thus, a technique that is useful in achieving one kind of common event analysis is often useful in achieving other kinds of common event analysis

    The LUSTRA program is focused on the greenhouse gases CO 2 and N 2 O, which are occurring in the atmosphere in increasing concentrations and causing a global warming effect. Carbon dioxide is being fixed in living biomass and released through respiration and decomposing processes. Nitrous oxide may be emitted, due to reduction processes, particularly from wet and nutrient-rich soils. Land use and soil management may significantly affect these processes, and a change in land use may induce reduced or increased emissions. The LUSTRA program vision is that strategic adaptation of land-use systems in managed forests in Sweden can greatly reduce net emissions of GHG. Forestry plays an important role through its potential to produce biomass for fossil fuel substitution and by sequestering carbon in standing biomass and soil organic matter including peat. Sweden has a land area of approximately 410,000 km 2 of which 226,000 km 2 (55 %) is forest land, defined as land suitable for forest production and with a potential mean stem production > 1m 3 /ha/y. With a population of around 9 million inhabitants this gives the second largest forest land area per capita in Europe. Due to this large forest land area, Sweden has a significant strategic potential to mitigate CO 2 emissions by management of forested land. During its first phase, 1999-2002, the primary objective of the program was to evaluate various land-use and management options with respect to emissions of GHG with the ultimate goal to suggest guidelines with strategies for optimized reduction in emissions. Since the start of LUSTRA, the external environment and conditions for the program have changed. First, the significance of the greenhouse-gas problem has increased partly due to growing common awareness of the magnitude of the problem and partly due and fueled by current extreme weather conditions. Secondly, the progress of international negotiations has stressed the national demand to participate on the global

  12. Common mental disorders among civil aviation pilots. (United States)

    Feijó, Denise; Luiz, Ronir Raggio; Camara, Volney Magalhães


    The purpose of this study was to estimate the prevalence of suspected cases of common mental disorders (CMD) on Brazilian civil aviation pilots and to investigate associations between CMD, demographics, and labor variables. A quantitative cross-sectional study was conducted on 807 working pilots between October 2009 and October 2010 using a self-administered questionnaire to obtain sociodemographic data and information about workload. CMD prevalence was estimated with the Self-Reporting Questionnaire-20 items (SRQ-20). Multiple logistic regression was used in statistical data analyses. The overall prevalence of CMD was 6.7% with the cutoff point of 8 used in this study, i.e., scores greater than or equal to 8 in SRQ-20 define positive cases. Using alternative cutoffs, the prevalence was 9.2% (cut off point 7) or 12% (cutoff point 6). Among the individuals who did not exercise, 10.2% presented suspected CMD. Among those with a heavy workload, 23.7% presented scores indicating suspected CMD. Only variables relating to workload and the practice of physical activity were significantly correlated with the estimate of CMD after multivariate analysis. Regular physical exercise afforded a possible protective effect against suspected cases of CMD, while there was a higher prevalence of suspected cases among subjects with heavy workloads. The inclusion of the topic of mental health among the targets and priorities of civil aviation in Brazil is imperative. Addressing issues such as the regular practice of physical activity and workload can contribute to achieving a better balance between flight safety and productivity.

  13. Intergroup Cooperation in Common Pool Resource Dilemmas. (United States)

    Sadowski, Jathan; Spierre, Susan G; Selinger, Evan; Seager, Thomas P; Adams, Elizabeth A; Berardy, Andrew


    Fundamental problems of environmental sustainability, including climate change and fisheries management, require collective action on a scale that transcends the political and cultural boundaries of the nation-state. Rational, self-interested neoclassical economic theories of human behavior predict tragedy in the absence of third party enforcement of agreements and practical difficulties that prevent privatization. Evolutionary biology offers a theory of cooperation, but more often than not in a context of discrimination against other groups. That is, in-group boundaries are necessarily defined by those excluded as members of out-groups. However, in some settings human's exhibit behavior that is inconsistent with both rational economic and group driven cooperation of evolutionary biological theory. This paper reports the results of a non-cooperative game-theoretic exercise that models a tragedy of the commons problem in which groups of players may advance their own positions only at the expense of other groups. Students enrolled from multiple universities and assigned to different multi-university identity groups participated in experiments that repeatedly resulted in cooperative outcomes despite intergroup conflicts and expressions of group identity. We offer three possible explanations: (1) students were cooperative because they were in an academic setting; (2) students may have viewed their instructors as the out-group; or (3) the emergence of a small number of influential, ethical leaders is sufficient to ensure cooperation amongst the larger groups. From our data and analysis, we draw out lessons that may help to inform approaches for institutional design and policy negotiations, particularly in climate change management.

  14. Common Avian Infection Plagued the Tyrant Dinosaurs (United States)

    Wolff, Ewan D. S.; Salisbury, Steven W.; Horner, John R.; Varricchio, David J.


    Background Tyrannosaurus rex and other tyrannosaurid fossils often display multiple, smooth-edged full-thickness erosive lesions on the mandible, either unilaterally or bilaterally. The cause of these lesions in the Tyrannosaurus rex specimen FMNH PR2081 (known informally by the name ‘Sue’) has previously been attributed to actinomycosis, a bacterial bone infection, or bite wounds from other tyrannosaurids. Methodology/Principal Findings We conducted an extensive survey of tyrannosaurid specimens and identified ten individuals with full-thickness erosive lesions. These lesions were described, measured and photographed for comparison with one another. We also conducted an extensive survey of related archosaurs for similar lesions. We show here that these lesions are consistent with those caused by an avian parasitic infection called trichomonosis, which causes similar abnormalities on the mandible of modern birds, in particular raptors. Conclusions/Significance This finding represents the first evidence for the ancient evolutionary origin of an avian transmissible disease in non-avian theropod dinosaurs. It also provides a valuable insight into the palaeobiology of these now extinct animals. Based on the frequency with which these lesions occur, we hypothesize that tyrannosaurids were commonly infected by a Trichomonas gallinae-like protozoan. For tyrannosaurid populations, the only non-avian dinosaur group that show trichomonosis-type lesions, it is likely that the disease became endemic and spread as a result of antagonistic intraspecific behavior, consumption of prey infected by a Trichomonas gallinae-like protozoan and possibly even cannibalism. The severity of trichomonosis-related lesions in specimens such as Tyrannosaurus rex FMNH PR2081 and Tyrannosaurus rex MOR 980, strongly suggests that these animals died as a direct result of this disease, mostly likely through starvation.

  16. Polarization Signals of Common Spacecraft Materials (United States)

    Gravseth, Ian; Culp, Robert D.; King, Nicole


    This is the final report documenting the results of the polarization testing of near-planar objects with various reflectance properties. The purpose of this investigation was to determine the portion of the reflected signal which is polarized for materials commonly used in space applications. Tests were conducted on several samples, with surface characteristics ranging from highly reflective to relatively dark. The measurements were obtained by suspending the test object in a beam of collimated light. The amount of light falling on the sample was controlled by a circular aperture placed in the light field. The polarized reflectance at various phase angles was then measured. A nonlinear least squares fitting program was used for analysis. For the specular test objects, the reflected signals were measured in one degree increments near the specular point. Otherwise, measurements were taken every five degrees in phase angle. Generally, the more diffuse surfaces had lower polarized reflectances than their more specular counterparts. The reflected signals for the more diffuse surfaces were spread over a larger phase angle range, while the signals from the more specular samples were reflected almost entirely within five degrees of angular deviation from the specular point. The method used to test all the surfaces is presented. The results of this study will be used to support the NASA Orbital Debris Optical Signature Tests. These tests are intended to help better understand the reflectance properties of materials often used in space applications. This data will then be used to improve the capabilities for identification and tracking of space debris.

  19. Aerodynamics of gliding flight in common swifts. (United States)

    Henningsson, P; Hedenström, A


    Gliding flight performance and wake topology of a common swift (Apus apus L.) were examined in a wind tunnel at speeds between 7 and 11 m s(-1). The tunnel was tilted to simulate descending flight at different sink speeds. The swift varied its wingspan, wing area and tail span over the speed range. Wingspan decreased linearly with speed, whereas tail span decreased in a nonlinear manner. For each airspeed, the minimum glide angle was found. The corresponding sink speeds showed a curvilinear relationship with airspeed, with a minimum sink speed at 8.1 m s(-1) and a speed of best glide at 9.4 m s(-1). Lift-to-drag ratio was calculated for each airspeed and tilt angle combinations and the maximum for each speed showed a curvilinear relationship with airspeed, with a maximum of 12.5 at an airspeed of 9.5 m s(-1). Wake was sampled in the transverse plane using stereo digital particle image velocimetry (DPIV). The main structures of the wake were a pair of trailing wingtip vortices and a pair of trailing tail vortices. Circulation of these was measured and a model was constructed that showed good weight support. Parasite drag was estimated from the wake defect measured in the wake behind the body. Parasite drag coefficient ranged from 0.30 to 0.22 over the range of airspeeds. Induced drag was calculated and used to estimate profile drag coefficient, which was found to be in the same range as that previously measured on a Harris' hawk.

  1. Dynamic transcriptome profiling of Bean Common Mosaic Virus (BCMV) infection in Common Bean (Phaseolus vulgaris L.). (United States)

    Martin, Kathleen; Singh, Jugpreet; Hill, John H; Whitham, Steven A; Cannon, Steven B


    Bean common mosaic virus (BCMV) is widespread, with Phaseolus species as the primary host plants. Numerous BCMV strains have been identified on the basis of a panel of bean varieties that distinguish the pathogenicity types with respect to the viral strains. The molecular responses in Phaseolus to BCMV infection have not yet been well characterized. We report the transcriptional responses of a widely susceptible variety of common bean (Phaseolus vulgaris L., cultivar 'Stringless green refugee') to two BCMV strains, in a time-course experiment. We also report the genome sequence of a previously unreported BCMV strain. The interaction with the known strain NL1-Iowa causes moderate symptoms and large transcriptional responses, and the newly identified strain (Strain 2 or S2) causes severe symptoms and moderate transcriptional responses. The transcriptional profiles of host plants infected with the two isolates are distinct, and involve numerous differences in splice forms in particular genes, and pathway specific expression patterns. We identified differential host transcriptome response after infection of two different strains of Bean common mosaic virus (BCMV) in common bean (Phaseolus vulgaris L.). Virus infection initiated a suite of changes in gene expression level and patterns in the host plants. Pathways related to defense, gene regulation, metabolic processes, photosynthesis were specifically altered after virus infection. Results presented in this study can increase the understanding of host-pathogen interactions and provide resources for further investigations of the biological mechanisms in BCMV infection and defense.

  6. Institutional property rights structure, common pool resource (CPR), tragedy of the urban commons: A Review

    International Nuclear Information System (INIS)

    Ling, G; Ho, C S; Ali, H M


    There have been a plethora of researches on the significance of public open space (POS) in contributing to societies' sustainability. However, by virtue of identified maladaptive policy-based-property rights structure, such a shared good becomes vulnerable to tragedy of the urban commons (overexploitation) that subsequently leads to burgeoning number of mismanaged POS e.g., degraded and unkempt urban public spaces. By scrutinising the literatures within property rights domain and commons resources, an objective is highlighted in this paper which is to insightfully discourse institutional property rights structure pertaining to the mechanism, roles and interrelationship between property-rights regimes, bundle of property rights and resource domains; types of goods on how they act upon and tie in the POS with the social quandary. In summary, urban POS tragedy can potentially be triggered by the institutional structure especially if the ownership is left under open-access resource regime and ill-defined property rights which both successively constitute the natures of Common Pool Resource (CPR) within the commons, POS. Therefore, this paper sparks an idea to policy makers that property rights structure is a determinant in sustainably governing the POS in which adaptive assignment of property regimes and property rights are impelled

CGS will expand to support JPSS-1 in 2017. The JPSS CGS currently does data processing (DP) for S-NPP, creating multiple TBs/day across over two dozen environmental data products (EDPs). The workload doubles after JPSS-1 launch. But CGS goes well beyond S-NPP & JPSS mission management & DP by providing data routing support to operational centers & missions worldwide. The CGS supports several other missions: It also provides raw data acquisition, routing & some DP for GCOM-W1. The CGS does data routing for numerous other missions & systems, including USN's Coriolis/Windsat, NASA's SCaN network (including EOS), NSF's McMurdo Station communications, Defense Meteorological Satellite Program (DMSP), and NOAA's POES & EUMETSAT's MetOp satellites. Each of these satellite systems orbits the Earth 14 times/day, downlinking data once or twice/orbit at up to 100s of MBs/second, to support the creation of 10s of TBs of data/day across 100s of EDPs. Raytheon and the US government invested much in Raytheon's mission-management, command & control and data-processing products & capabilities. CGS's flexible

  17. Common features of tuberculosis and sarcoidosis

    Directory of Open Access Journals (Sweden)

    Esmaeil Mortaz


    Full Text Available Tuberculosis (TB is a disease caused by Mycobacterium tuberculosis. Despite the availability of novel therapeutic approaches, TB is considered as one of the leading causes of death due to infectious diseases worldwide. Alveolar macrophages are the first line of defense against M. tuberculosis; they ingest and sequester the bacilli within granulomatous structures. Control and resolution of the infection requires activated T lymphocytes as well as Th1 cytokines. There are two forms of TB: active TB and latent TB. Latent TB is a state in which M. tuberculosis survives in the body without causing overt signs and symptoms. People with latent TB are noncontagious. However, M. tuberculosis can become active in the body, multiply, and cause overt TB. Sarcoidosis, on the other hand, is an autoimmune disease of unknown etiology which can affect multiple systems of the body. Nonspecific constitutional symptoms, such as fever, fatigue, malaise, and weight loss, are present in approximately one-third of patients. Chest X-ray usually shows hilar and mediastinal lymphadenopathy. Although the lungs are the most common sites of inflammation, sarcoidosis can also involve other organs, such as the eyes (intraocular and adnexal, skin, lymph nodes, salivary glands, heart, spleen, liver, and the nervous system. Recent investigations have provided further insights into the genetic basis of sarcoidosis and the way genotype determines the clinical presentation and phenotype of patients. Histopathologic features are usually insufficient for diagnosis of sarcoidosis. Diagnosis of sarcoidosis in endemic areas for TB can become a great challenge. Both TB and sarcoidosis are granulomatous diseases; TB is characterized by caseating granulomas, whereas sarcoidosis is characterized by noncaseating granulomas. New cases of sarcoidosis are increasingly being diagnosed in areas endemic for TB due to increased orientation of physicians and availability of diagnostic modalities

  18. Commons - Whose Commons? - considering conceptual approaches to rural space of production

    DEFF Research Database (Denmark)

    Ingemann, Jan Holm

    The article takes its point of departure in current suggestions stating that the idea of ‘commons’ could be a universal and normative guideline for how to organise a part of the interplay between nature and human activity. It is stated, that the concept in contemporary discourses has a widespread...... spectrum of connotations and is engaged for descriptive, prescriptive, and normative purposes.

  19. Teaching strategies in the learning of highest common factor and lowest common multiple (United States)

    Halim, N. L. A.; Li, H.-C.; Shahrill, M.; Prahmana, R. C. I.


    The main purpose of this study is to improve students’ understanding of Highest Common Factor (HCF) and Lowest Common Multiple (LCM). Several alternative teaching strategies were integrated in the Year 7 lessons involving 20 students from one secondary school in Brunei Darussalam. The categories identified in the teaching strategy were the application of group work, embedding real-life problems, using presentations and the traditional drilling practice method. An open-ended survey was disseminated to collate the students’ feedback, and among the questions posed was in relation to the different types of lesson activities utilised within each of the teaching strategies. Although 55% of the students preferred the traditional drilling practice on the calculation of HCF and LCM, mainly due to the ease of the task as opposed to activities involving real-life problems, the findings also indicated that most students favour sharing their ideas in a healthy competition learning style between each other or between the groups.

  20. Cerebral microbleeds: a magnetic resonance imaging review of common and less common causes. (United States)

    Renard, D


    Cerebral microbleeds (CMBs) are small foci of (acute, subacute or chronic) blood products, best seen using magnetic resonance imaging (MRI) techniques sensitive to iron deposits (i.e. gradient-echo T2*-weighted and susceptibility-weighted imaging), frequently encountered in small vessel disease (SVD) (with hypertensive vasculopathy and cerebral amyloid angiopathy as the most frequent conditions) and also in other disorders. In this review, the MRI characteristics of CMBs and the associated MRI abnormalities encountered in common and less common SVD and non-SVD conditions are the main focus. Identification of the origin of CMBs depends on their localization, the presence of other associated MRI abnormalities, and the patient's history and clinical state. © 2017 EAN.

  1. Improving patient safety reporting with the common formats: Common data representation for Patient Safety Organizations. (United States)

    Elkin, Peter L; Johnson, Henry C; Callahan, Michael R; Classen, David C


    Medical errors and patient safety issues remain a significant problem for the healthcare industry in the United States. The Institute of Medicine report To Err is Human reported that there were as many as 98,000 deaths per year due to medical error as of 1999. Many authors and government officials believe that the first step on the path to improvement in patient safety is more comprehensive collection and analysis of patient safety events. The belief is that this will enable safety improvements based on data showing the nature and frequency of events that occur, and the effectiveness of interventions. This systematization of healthcare practice can be a step in the right direction toward a value based, safety conscious and effective healthcare system. To help standardize this reporting and analysis, AHRQ created Common Formats for Patient Safety data collection and reporting. This manuscript describes the development of patient safety reporting and learning through the Patient Safety Organizations (PSO)s and the Common Formats and gives readers an overview of how the system is expected to function and the breadth of development of the Common Formats to date.

  2. Are common names becoming less common? The rise in uniqueness and individualism in Japan

    Directory of Open Access Journals (Sweden)

    Yuji eOgihara


    Full Text Available We examined whether Japanese culture has become more individualistic by investigating how the practice of naming babies has changed over time. Cultural psychology has revealed substantial cultural variation in human psychology and behavior, emphasizing the mutual construction of socio-cultural environment and mind. However, much of the past research did not account for the fact that culture is changing. Indeed, archival data on behavior (e.g., divorce rates suggest a rise in individualism in the U.S. and Japan. In addition to archival data, cultural products (which express an individual’s psyche and behavior outside the head; e.g., advertising can also reveal cultural change. However, little research has investigated the changes in individualism in East Asia using cultural products. To reveal the dynamic aspects of culture, it is important to present temporal data across cultures. In this study, we examined baby names as a cultural product. If Japanese culture has become more individualistic, parents would be expected to give their children unique names. Using two databases, we calculated the rate of popular baby names between 2004 and 2013. Both databases released the rankings of popular names and their rates within the sample. As Japanese names are generally comprised of both written Chinese characters and their pronunciations, we analyzed these two separately. We found that the rate of popular Chinese characters increased, whereas the rate of popular pronunciations decreased. However, only the rate of popular pronunciations was associated with a previously validated collectivism index. Moreover, we examined the pronunciation variation of common combinations of Chinese characters and the written form variation of common pronunciations. We found that the variation of written forms decreased, whereas the variation of pronunciations increased over time. Taken together, these results showed that parents are giving their children unique names by

  3. MDEP Common Position No EPR-01 - Common positions on the EPR instrumentation and controls design

    International Nuclear Information System (INIS)


    The purpose of the EPR Working Group (EPRWG) of the Multinational Design Evaluation Program (MDEP) is to identify common positions among the regulators reviewing the EPR Instrumentation and Controls (I and C) Systems in order to: 1. Promote understanding of each country 's regulatory decisions and basis for the decisions, 2. Enhance communication among the members and with external stakeholders, 3. Identify areas where harmonization and convergence of regulations, standards, and guidance can be achieved or improved, and 4. Supports standardization of new reactor designs. Since January 2008, the EPR I and C Technical Expert Subgroup (TESG) members met five times to exchange information regarding their country 's review of the EPR I and C design. The EPR I and C TESG consists of regulators from China, Canada, Finland, France, the United Kingdom, and the United States. The information exchange includes presentation of each country 's review status and technical issues, sharing of guidance documents, and sharing of regulatory decision documents. The TESG focused on the following four core areas of the EPR I and C design: 1. I and C System Independence (particularly for data communications), 2. Level of Defense and Diversity (back-up systems), 3. Qualification/quality of digital platforms, 4. Categorization/classification of systems and functions. As meetings were conducted, some areas were emphasized more depending on the significance of the issues for each country. During the TESG interactions, it became apparent that there were aspects of the EPR design where the countries had common agreement. On November 2, 2009, three of the subgroup countries, France, Finland and the United Kingdom, issued a joint regulatory position on the EPR I and C design as result of the 'Groupe Permanent' meeting in France. This statement of common positions expands upon that joint regulatory position

  4. Angiomyolipoma have common mutations in TSC2 but no other common genetic events.

    Directory of Open Access Journals (Sweden)

    Wei Qin

    Full Text Available Renal angiomyolipoma are part of the PEComa family of neoplasms, and occur both in association with Tuberous Sclerosis Complex (TSC and independent of that disorder. Previous studies on the molecular genetic alterations that occur in angiomyolipoma are very limited. We evaluated 9 angiomyolipoma for which frozen tissue was available from a consecutive surgical series. Seven of 8 samples subjected to RT-PCR-cDNA sequencing showed mutations in TSC2; none showed mutations in TSC1 or RHEB. Six of the seven mutations were deletions. We searched for 983 activating and inactivating mutations in 115 genes, and found none in these tumors. Similarly analysis for genomic regions of loss or gain, assessed by Affymetrix SNP6.0 analysis, showed no abnormalities. Loss of heterozygosity in the TSC2 region was commonly seen, except in patients with low frequency TSC2 mutations. We conclude that sporadic renal angiomyolipoma usually have mutations in TSC2, but not TSC1 or RHEB, and have no other common genomic events, among those we searched for. However, chromosomal translocations and gene fusion events were not assessed here. TSC2 inactivation by mutation is a consistent and likely necessary genetic event in the pathogenesis of most angiomyolipoma.

  5. Pre-Clinical Traumatic Brain Injury Common Data Elements: Toward a Common Language Across Laboratories. (United States)

    Smith, Douglas H; Hicks, Ramona R; Johnson, Victoria E; Bergstrom, Debra A; Cummings, Diana M; Noble, Linda J; Hovda, David; Whalen, Michael; Ahlers, Stephen T; LaPlaca, Michelle; Tortella, Frank C; Duhaime, Ann-Christine; Dixon, C Edward


    Traumatic brain injury (TBI) is a major public health issue exacting a substantial personal and economic burden globally. With the advent of "big data" approaches to understanding complex systems, there is the potential to greatly accelerate knowledge about mechanisms of injury and how to detect and modify them to improve patient outcomes. High quality, well-defined data are critical to the success of bioinformatics platforms, and a data dictionary of "common data elements" (CDEs), as well as "unique data elements" has been created for clinical TBI research. There is no data dictionary, however, for preclinical TBI research despite similar opportunities to accelerate knowledge. To address this gap, a committee of experts was tasked with creating a defined set of data elements to further collaboration across laboratories and enable the merging of data for meta-analysis. The CDEs were subdivided into a Core module for data elements relevant to most, if not all, studies, and Injury-Model-Specific modules for non-generalizable data elements. The purpose of this article is to provide both an overview of TBI models and the CDEs pertinent to these models to facilitate a common language for preclinical TBI research.

Coordenacao dos Programas de Pos-graduacao de Engenharia (COPPE); Jesus, Carlos A.C. [Universidade Federal Fluminense (UFF), Niteroi, RJ (Brazil)


    The quality of seismic data can be degrade by effects originated from a complex near surface, like the presence of canyons in marine floor. Filgueiras (2007) introduced a new formulation for data recorded redatuming on surface that are influenced by canyons present in marine floor, using the concept of Common Focus Point (CFP) Gather, with wave field extrapolations without asymptotic approximations. This new formulation proposes to eliminate the effects of the floor marine topography (Filgueiras, 2007). It is based on the concepts of CFP technology introduced by Berkhout (1997 a. and 1997 b.) and the virtual source method, introduced by Bakulin and Calvert (2004). This procedure implies a new datum a final seismogram redatuming, capable to show the reflections with no canyons influence of the most all reflectors that are under the reference datum. From cinematic point at view, the results from synthetic data were satisfied. (author)

  4. A Quantitative Method to Screen Common Bean Plants for Resistance to Bean common mosaic necrosis virus. (United States)

    Strausbaugh, C A; Myers, J R; Forster, R L; McClean, P E


    ABSTRACT A quantitative method to screen common bean (Phaseolus vulgaris) plants for resistance to Bean common mosaic necrosis virus (BCMNV) is described. Four parameters were assessed in developing the quantitative method: symptoms associated with systemic virus movement, plant vigor, virus titer, and plant dry weight. Based on these parameters, two rating systems (V and VV rating) were established. Plants from 21 recombinant inbred lines (RILs) from a Sierra (susceptible) x Olathe (partially resistant) cross inoculated with the BCMNV-NL-3 K strain were used to evaluate this quantitative approach. In all, 11 RILs exhibited very susceptible reactions and 10 RILs expressed partially resistant reactions, thus fitting a 1:1 susceptible/partially resistant ratio (chi(2) = 0.048, P = 0.827) and suggesting that the response is mediated by a single gene. Using the classical qualitative approach based only on symptom expression, the RILs were difficult to separate into phenotypic groups because of a continuum of responses. By plotting mean percent reduction in either V (based on visual symptoms) or VV (based on visual symptoms and vigor) rating versus enzyme-linked immunosorbent assay (ELISA) absorbance values, RILs could be separated clearly into different phenotypic groups. The utility of this quantitative approach also was evaluated on plants from 12 cultivars or pure lines inoculated with one of three strains of BCMNV. Using the mean VV rating and ELISA absorbance values, significant differences were established not only in cultivar and pure line comparisons but also in virus strain comparisons. This quantitative system should be particularly useful for the evaluation of the independent action of bc genes, the discovery of new genes associated with partial resistance, and assessing virulence of virus strains.

  5. Scientists and Faith Communities in Dialogue - Finding Common Ground to Care for our Common Home (United States)

    Jablonski, L. M.


    World-wide, faith communities are a key place for education and outreach to the general adult population. The sacred responsibility to care for the earth, living sustainability and concern for the poor are nearly universal priorities across faith communities. Scientists and people of faith share in common experiences of awe and wonder and ethical roles as citizens. The majority of faith communities have statements on climate changes, environmental justice, and stewardship, and respond with education, action plans and advocacy. People of faith are increasingly seeking science expertise to better understand the science and best solutions to implement. Transformation of point of view often requires heart-felt motivation (domain of religion) as well as knowledge (science). Scientists can participate in alleviating environmental justice by providing data and education to communities. Expert testimony is a critical service. Pope Francis' environmental encyclical Laudato si, engaged diverse scientists in its writing and outreach. Francis invites our continued dialogue with people of faith and goodwill of all societal sectors and fields to achieve an integral ecology that integrates science, economics, and impacts on the poor. For scientists to be most effective in sharing expertise, and building understanding and trust in scientific findings, skill- building is needed in: communication, finding common ground, intercultural competency, working with diverse populations and religious literacy. Educational initiatives bridging scientists and faith-communities will be highlighted including within: the Ecological Society of America, American Assn for Advancement of Sustainability in Higher Education, faith-based & Environmental Justice networks, Nature centers, Higher Education (including Seminary) Initiatives and the Hanley Sustainability Institute, and interfaith religious organizations engaged with scientists.

    Meitzler, W.D.


    In the context of this document and COE, the Geographic Information Systems (GIS) are decision support systems involving the integration of spatially referenced data in a problem solving environment. They are digital computer systems for capturing, processing, managing, displaying, modeling, and analyzing geographically referenced spatial data which are described by attribute data and location. The ability to perform spatial analysis and the ability to combine two or more data sets to create new spatial information differentiates a GIS from other computer mapping systems. While the CCGIS allows for data editing and input, its primary purpose is not to prepare data, but rather to manipulate, analyte, and clarify it. The CCGIS defined herein provides GIS services and resources including the spatial and map related functionality common to all subsystems contained within the COE suite of C4I systems. The CCGIS, which is an integral component of the COE concept, relies on the other COE standard components to provide the definition for other support computing services required.

  7. The Most Common Herbs to Cure the Most Common Oral Disease: Stomatitis Recurrent Aphthous Ulcer (RAU). (United States)

    Hamedi, Shokouhsadat; Sadeghpour, Omid; Shamsardekani, Mohammad Reza; Amin, Gholamreza; Hajighasemali, Dawood; Feyzabadi, Zohreh


    Recurrent aphthous ulcer (RAU) is an oral disease and the most common oral lesion, with 2% to 66% of the world's population infected annually. Its prevalence is about 25% in Tehran and 27.6% in Mashhad. The etiology of RAU is multifactorial. Aphthous risk factors include: immunological factors, psychological factors, stress, trauma, sensitivity, family history, blood disorders, malnutrition, and use of certain medications, It should be noted that the best treatment for RAU is the topical application of drugs. The use of topical treatments is recommended not only because the drug can directly impact the source of the disease, but also systemic side effects of the drug are reduced. Treatment of RAU has been considered in Iranian traditional medicine (ITM), and is covered in therapeutic books. The use of herbs in RAU has a centuries-old history; accordingly, extensive research should be conducted for this treatment of the disease. Iranian medical sources were reviewed and effective plants used in the traditional treatment of RAU were found and compared with new findings. Finally, we have created a table listing the plants that are part of the therapeutic protocol for RAU. Based on this article we can explain some of traditional pharmacological effects of plants and how these plants can be a source for a cure. The plants listed can be used as a prediction of RAU management. Of course, there are is no evidence for curing RAU by some of these plants in allopathic medicine, and the further investigations in this area could lead to the discovery of a new drug.

  14. Do Reichenbachian Common Cause Systems of Arbitrary Finite Size Exist? (United States)

    Mazzola, Claudio; Evans, Peter W.


    The principle of common cause asserts that positive correlations between causally unrelated events ought to be explained through the action of some shared causal factors. Reichenbachian common cause systems are probabilistic structures aimed at accounting for cases where correlations of the aforesaid sort cannot be explained through the action of a single common cause. The existence of Reichenbachian common cause systems of arbitrary finite size for each pair of non-causally correlated events was allegedly demonstrated by Hofer-Szabó and Rédei in 2006. This paper shows that their proof is logically deficient, and we propose an improved proof.

    Full Text Available We consider problem of assembling a common image of VLSI layout. Common image is composedof frames obtained by electron microscope photographing. Many frames require a lot of computation for positioning each frame inside the common image. Employing graphics processing units enables acceleration of computations. We realize algorithms and programs for assembling a common image of VLSI layout. Specificity of this work is to use abilities of CUDA to reduce computation time. Experimental results show efficiency of the proposed programs.

  17. Defense against common-mode failures in protection system design

    Wyman, R.H.; Johnson, G.L.


    The introduction of digital instrumentation and control into reactor safety systems creates a heightened concern about common-mode failure. This paper discusses the concern and methods of cope with the concern. Common-mode failures have been a 'fact-of-life' in existing systems. The informal introduction of defense-in-depth and diversity (D-in-D and D) - coupled with the fact that hardware common-mode failures are often distributed in time - has allowed systems to deal with past common-mode failures. However, identical software operating in identical redundant systems presents the potential for simultaneous failure. Consequently, the use of digital systems raises the concern about common-mode failure to a new level. A more methodical approach to mitigating common-mode failure is needed to address these concerns. Purposeful introduction of D-in-D and D has been used as a defense against common-mode failure in reactor protection systems. At least two diverse systems are provided to mitigate any potential initiating event. Additionally, diverse displays and controls are provided to allow the operator to monitor plant status and manually initiate engineered safety features. A special form of common-mode failure analysis called 'defense-in-depth and diversity analysis' has been developed to identify possible common-mode failure vulnerabilities in digital systems. An overview of this analysis technique is provided. (author)

  18. A content analysis of tweets about high-potency marijuana. (United States)

    Cavazos-Rehg, Patricia A; Sowles, Shaina J; Krauss, Melissa J; Agbonavbare, Vivian; Grucza, Richard; Bierut, Laura


    "Dabbing" involves heating extremely concentrated forms of marijuana to high temperatures and inhaling the resulting vapor. We studied themes describing the consequences of using highly concentrated marijuana by examining the dabbing-related content on Twitter. Tweets containing dabbing-related keywords were collected from 1/1-1/31/2015 (n=206,854). A random sample of 5000 tweets was coded for content according to pre-determined categories about dabbing-related behaviors and effects experienced using a crowdsourcing service. An examination of tweets from the full sample about respiratory effects and passing out was then conducted by selecting tweets with relevant keywords. Among the 5000 randomly sampled tweets, 3540 (71%) were related to dabbing marijuana concentrates. The most common themes included mentioning current use of concentrates (n=849; 24%), the intense high and/or extreme effects from dabbing (n=763; 22%) and excessive/heavy dabbing (n=517; 15%). Extreme effects included both physiological (n=124/333; 37%) and psychological effects (n=55/333; 17%). The most common physiologic effects, passing out (n=46/333; 14%) and respiratory effects (n=30/333; 9%), were then further studied in the full sample of tweets. Coughing was the most common respiratory effect mentioned (n=807/1179; 68%), and tweeters commonly expressed dabbing with intentions to pass out (416/915; 45%). This study adds to the limited understanding of marijuana concentrates and highlights self-reported physical and psychological effects from this type of marijuana use. Future research should further examine these effects and the potential severity of health consequences associated with concentrates. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    The results of experimental studies of coordinate distributions of Mueller matrix elements of the following types of cervical scraping tissue are presented: rate- low-grade - highly differentiated dysplasia (CIN1-CIN3) - adenocarcinoma of high, medium and low levels of differentiation (G1-G3). The rationale for the choice of statistical points 1-4 orders polarized coherent radiation field, transformed as a result of interaction with the oncologic modified biological layers "epithelium-stroma" as a quantitative criterion of polarimetric optical differentiation state of human biological tissues are shown here. The analysis of the obtained Mueller matrix elements and statistical correlation methods, the systematized by types studied tissues is accomplished. The results of research images of Mueller matrix elements m34 for this type of pathology as low-grade dysplasia (CIN2), the results of its statistical and correlation analysis are presented.
