  2. The COD Model: Simulating Workgroup Performance

    Science.gov (United States)

    Biggiero, Lucio; Sevi, Enrico

    Though the question of the determinants of workgroup performance is one of the most central in organization science, precise theoretical frameworks and formal demonstrations are still missing. In order to fill in this gap the COD agent-based simulation model is here presented and used to study the effects of task interdependence and bounded rationality on workgroup performance. The first relevant finding is an algorithmic demonstration of the ordering of interdependencies in terms of complexity, showing that the parallel mode is the most simplex, followed by the sequential and then by the reciprocal. This result is far from being new in organization science, but what is remarkable is that now it has the strength of an algorithmic demonstration instead of being based on the authoritativeness of some scholar or on some episodic empirical finding. The second important result is that the progressive introduction of realistic limits to agents' rationality dramatically reduces workgroup performance and addresses to a rather interesting result: when agents' rationality is severely bounded simple norms work better than complex norms. The third main finding is that when the complexity of interdependence is high, then the appropriate coordination mechanism is agents' direct and active collaboration, which means teamwork.

    The Climate Adaptation Science Investigators (CASI) Workgroup is comprised of NASA Earth scientists, applications researchers and institutional stewards, tasked with assisting the development of Climate Change Adaptation strategies for NASA as a whole as well as at individual Centers. In an Executive Order dated October 5, 2009, titled "Federal Leadership in Environmental, Energy, and Economic Performance" the President mandates that all agencies "evaluate agency climate-change risks and vulnerabilities to manage the effects of climate change on the agency's operations and mission in both the short and long-term." To further these goals, the CASI Workgroup contributes to the scientific advancement of relevant climate and impacts studies at the Center-scale, contributes to a body of knowledge on how to apply Earth science in decision-making and ensures that NASA institutional stewards' decision-making process benefits from the best available scientific information. Climate variability and climate change pose a range of hazards to the NASA Centers located throughout the country. These changing climate hazards may challenge key NASA missions by threatening operations and damaging critical infrastructure. Studying and understanding these hazards are essential to ensuring effective risk management for the centers. By developing climate change adaptation strategies tailored to the specific impacts that are anticipated, NASA decision makers will be able to minimize negative effects of climate and climate change, while leveraging positive outcomes. The NASA CASI Workgroup will perform a variety of tasks including development of climate projections for each Center, inventory of climate and climate impact data and project activities within NASA, assessment of adaption approaches and Center-level planning strategies, recommendations for future research initiatives, and leading of thematic and region-specific workshops.

    This article develops a theoretical model of the impact of workplace incivility on employees' occupational and psychological well-being. In Study 1, the authors tested the model on 1,158 employees, finding that satisfaction with work and supervisors, as well as mental health, partially mediated effects of personal incivility on turnover intentions and physical health; this process did not vary by gender. Study 2 cross-validated and extended these results on an independent sample of 271 employees, showing negative effects of workgroup incivility that emerged over and above the impact of personal incivility. In both studies, all results held while controlling for general job stress. Implications for organizational science and practice are discussed. 2008 APA

    The National Technical Workgroup on Mixed Waste Thermal Treatment held its annual meeting in Atlanta Georgia on March 12-14, 1996. The National Technical Workgroup (NTW) and this meeting were sponsored under an interagency agreement between EPA and DOE. The 1996 Annual Meeting was hosted by US DOE Oak Ridge Operations in conjunction with Lockheed Martin Energy Systems - Center for Waste Management. A new feature of the annual meeting was the Permit Writer Panel Session which provided an opportunity for the state and federal permit writers to discuss issues and potential solutions to permitting mixed waste treatment systems. In addition, there was substantial discussion on the impacts of the Waste Combustion Performance Standards on mixed waste thermal treatment which are expected to proposed very soon. The 1996 meeting also focussed on two draft technical resource documents produced by NTW on Waste Analysis Plans and Compliance Test Procedures. Issues discussed included public involvement, waste characterization, and emission issues.

    Almost all residency programs require a resident research project, yet teaching and mentoring of the required skills are often lacking. We established an every-other-week gynecologic oncology research workgroup at our institution for obstetrics and gynecology faculty, fellows, and residents with the goal of increasing resident research education, involvement, and productivity. An informal, discussion-style format was adopted as a forum for brainstorming research ideas, formulating study protocols, and collaborating on institutional review board submissions. Additional aims included editorial feedback on abstracts and manuscripts as well as oral presentation preparation. The academic productivity of trainees mentored by the gynecologic oncology division was queried for 27 months before and 27 months after workgroup initiation, specifically assessing resident involvement in institutional review board submission, abstract presentation, and manuscript preparation. Institution of our workgroup was associated with a dramatic increase in resident research output, including manuscript preparation and presentations at national meetings. We describe our experience because it may benefit other residency programs wishing to improve both resident research education and productivity.

  9. Making sense of the "clean label" trends: A review of consumer food choice behavior and discussion of industry implications.

    Consumers in industrialized countries are nowadays much more interested in information about the production methods and components of the food products that they eat, than they had been 50years ago. Some production methods are perceived as less "natural" (i.e. conventional agriculture) while some food components are seen as "unhealthy" and "unfamiliar" (i.e. artificial additives). This phenomenon, often referred to as the "clean label" trend, has driven the food industry to communicate whether a certain ingredient or additive is not present or if the food has been produced using a more "natural" production method (i.e. organic agriculture). However, so far there is no common and objective definition of clean label. This review paper aims to fill the gap via three main objectives, which are to a) develop and suggest a definition that integrates various understandings of clean label into one single definition, b) identify the factors that drive consumers' choices through a review of recent studies on consumer perception of various food categories understood as clean label with the focus on organic, natural and 'free from' artificial additives/ingredients food products and c) discuss implications of the consumer demand for clean label food products for food manufacturers as well as policy makers. We suggest to define clean label, both in a broad sense, where consumers evaluate the cleanliness of product by assumption and through inference looking at the front-of-pack label and in a strict sense, where consumers evaluate the cleanliness of product by inspection and through inference looking at the back-of-pack label. Results show that while 'health' is a major consumer motive, a broad diversity of drivers influence the clean label trend with particular relevance of intrinsic or extrinsic product characteristics and socio-cultural factors. However, 'free from' artificial additives/ingredients food products tend to differ from organic and natural products. Food

    The aim of this study is to extend the Channel Model of Flow (Csikszentmihalyi, 1975, 1990) at the collective level (workgroups) by including collective efficacy beliefs as a predictor of collective flow based on the Social Cognitive Theory (Bandura, 1997, 2001). A two-wave longitudinal lab study was conducted with 250 participants working in 52 small groups. Longitudinal results from Structural Equation Modeling with data aggregated at the group level showed, as expected, that collective efficacy beliefs predict collective flow over time, both being related reciprocally. Findings and their theoretical and practical implications in the light of Social Cognitive Theory are discussed.

    Rising seas are expected to have significant impacts on infrastructure and natural and cultural resources on New Hampshire's 18 mile open-ocean coastline and 235 miles of tidal shoreline. However, most coastal municipalities in NH lack financial and human resources to even assess vulnerability, let alone plan for climate change. This gap has been filled since 2010 by the NH Coastal Adaptation Workgroup (CAW), composed of 21 regional, state, and federal agencies, businesses, municipalities, academics, and NGOs that bring together stakeholders to discuss climate change challenges and collaboratively develop and implement effective coastal adaptation strategies. Our grassroot efforts serve to nurture existing and build new relationships, disseminate coastal watershed climate assessments, and tap into state, federal, and foundation funds for specific coastal adaptation projects. CAW has achieved collective impact in by connecting federal and state resources to communities by raising money and facilitating projects, translating climate science, educating community members, providing direct technical assistance and general capacity, and sharing success stories and lessons learned. Indicators of success include: 12 coastal communities improved their technical, financial, and human resources for climate adaptation; 80% of the 300 participants in the eleven CAW 'Water, Weather, Climate, and Community Workshops' have increased knowledge, motivation, and capacity to address climate adaptation; $3 million in grants to help communities with climate adaptation; winner of the 2015 EPA Region 1 Environmental Merit Award; and ongoing support for community-led adaptation efforts. In addition, the NH Climate Summit attracts over 100 participants each year, over 90% whom attest to the applicability of what they learn there. CAW also plays a central role in the Coastal Risks and Hazards Commission (established by the state legislature in 2013) to help communities and businesses prepare

    Full Text Available This paper develops a version of Robust Stochastic Maximum Principle (RSMP applied to the Minimax Mayer Problem formulated for stochastic differential equations with the control-dependent diffusion term. The parametric families of first and second order adjoint stochastic processes are introduced to construct the corresponding Hamiltonian formalism. The Hamiltonian function used for the construction of the robust optimal control is shown to be equal to the Lebesque integral over a parametric set of the standard stochastic Hamiltonians corresponding to a fixed value of the uncertain parameter. The paper deals with a cost function given at finite horizon and containing the mathematical expectation of a terminal term. A terminal condition, covered by a vector function, is also considered. The optimal control strategies, adapted for available information, for the wide class of uncertain systems given by an stochastic differential equation with unknown parameters from a given compact set, are constructed. This problem belongs to the class of minimax stochastic optimization problems. The proof is based on the recent results obtained for Minimax Mayer Problem with a finite uncertainty set [14,43-45] as well as on the variation results of [53] derived for Stochastic Maximum Principle for nonlinear stochastic systems under complete information. The corresponding discussion of the obtain results concludes this study.

    In this presentation, the presenter will review what was done at Kennedy Space Center to deploy and implement PTC MathCAD and PTC Workgroup Manager in a multi-org system. During the presentation the presenter will explain how they configured PTC Windchill to create custom soft-types and object initialization rules for their custom numbering scheme and why they choose these methods. This presentation will also include how to modify the EPM default soft-type file in the PTC Windchill server codebase folder. The presenter will also go over the code used in a start up script to initiate PTC MathCAD and PTC Workgroup Manager in the proper order, and also set up the environment variables when running both PTC Workgroup Manager and PTC Creo. The configuration.ini file the presenter used will also be reviewed to show you how to set up the PTC Workgroup Manager and customized it to their user community. This presentation will be of interest to administrators trying to create a similar set-up in either a single org or multiple org system deployment. The big take away will be ideas and best practices learned through implementing this system, and the lessons learned what to do and not to do when setting up this configuration. Attendees will be exposed to several different sets of code used and that worked well and will hear some limitations on what the software can accomplish when configured this way.

    2016-01-01

    Diversity climate, defined as an organizational climate characterized by openness towards and appreciation of individual differences, has been shown to enhance outcomes in culturally diverse teams. To date, it remains unclear which processes are responsible for these findings. This paper presents two quantitative studies (n = 91; 246) that identify trust and openness in workgroup communication as possible mediators. We replicate earlier findings that perceived diversity climate positively relates to job satisfaction, sense of inclusion, work group identification and knowledge sharing in teams. In study 1, trust is shown to mediate the effects of perceived diversity climate on team members' sense of inclusion. In study 2, trust mediates the relationship between perceived diversity climate and workgroup identification and openness mediates its relationship with knowledge sharing.

    2015-03-01

    Full Text Available The purpose of this study was to examine whether managerial self-awareness (defined as degree of agreement between self and subordinate ratings of leaders’ behaviors mediates the relationship between supervisor burnout and supervised workgroup climate. Using an HLM approach, supervisor emotional exhaustion, depersonalization and personal accomplishment exhibited significant indirect relationships with workplace Civility and Psychological Safety, via managerial self-awareness. No direct relationships between supervisor burnout and workgroup climate were found, suggesting that self-awareness may be an important mediator for individual characteristics of leaders previously thought to be non-significant. Additional post hoc comparisons indicated that workgroups with supervisors who over-rated their own performance behaviors reported the lowest levels of Civility and Psychological Safety compared to workgroups with supervisors who accurately rated or under-rated their own performance behaviors. However, supervisors that under-rated their own performance reported the highest levels of burnout, highlighting the importance of self-awareness (accurately rating oneself in relation to individual and group outcomes. The relationships between supervisor burnout, managerial self-awareness, and workgroup perceptions of Civility and Psychological Safety differed when considering the directionality of self-other rating agreement, with the negative impact of burnout at the supervisor level having a more direct impact on the workgroup level perceptions of Civility and Psychological Safety when the workgroup is managed by an under-rater, as opposed to an accurate- or over-rater. Practically, organizations should consider the role of managerial self-awareness in influencing subordinate performance and creating desirable work climates. Also, this study suggests the effects of burnout extend beyond the individual and have significant implications for the performance

    2002-12-15

    OAK-B135 A symposium discussing the implications of certain phenomena observed in radiation biology for cancer risk assessment in general. In July of 2002 a workshop was convened that explored some of the intercellular phenomena that appear to condition responses to carcinogen exposure. Effects that result from communication between cells that appear to either increase the sphere of damage or to modify the sensitivity of cells to further damage were of particular interest. Much of the discussion focused on the effects of ionizing radiation that were transmitted from cells directly hit to cells not receiving direct exposure to radiation (bystander cells). In cell culture, increased rates of mutation, chromosomal aberration, apoptosis, genomic instability, and decreased clonogenic survival have all been observed in cells that have experienced no direct radiation. In addition, there is evidence that low doses of radiation or certain chemicals give rise to adaptive responses in which the treated cells develop resistance to the effects of high doses given in subsequent exposures. Data were presented at the workshop indicating that low dose exposure of animals to radiation and some chemicals frequently reduces the spontaneous rate of mutation in vitro and tumor responses in vivo. Finally, it was concluded that considerable improvement in understanding of how genetic variation may modify the impact of these phenomena is necessary before the risk implications can be fully appreciated. The workshop participants discussed the substantive challenge that these data present with respect to simple linear methodologies that are currently used in cancer risk assessment and attempted to identify broad strategies by which these phenomena may start to be used to refine cancer risk assessment methods in the future.

  13. Strategies for a Successful Anatomic Pathology Subspecialty Workgroup

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available From 1990 to present, 14 liver pathologists and 2 clinical hepatologists from 9 countries have met annually to hold thematic 2.5-day meetings centered on case-based discussion. The goal of these meetings has been to identify gaps in knowledge in our field and fuel scholarly effort to address these gaps. The founding principles were worldwide representation, good representation of women, compatibility of participants, commitment to stable membership and regular attendance, mutual education and friendship, and free exchange of ideas. A summary report of the 2.5-day meeting constituted an enduring document that captured the free flow of ideas discussed. These ideas were open to all participants for the pursuit of scholarship back at their home institutions. However, any idea borne out of an Elves meeting merits open invitation for other Elves to participate in, using established standards for meaningful coauthorship. Over 26 consecutive meetings (1990-2015, themes covered the breadth of liver pathology. With retirement of 2 individuals, resignation of 3, and death of 1, six new members were nominated and voted into membership. Over these same 26 years, active members published 2025 articles indexed in PubMEd Central under the topic “liver;” 3% of these articles represented collaborations between members. This international group represents a successful model in a subspecialty of anatomic pathology for open exchange of ideas, mutual education, and generation of topics worthy of scholarly investigation. We conclude that a self-selected group of subspecialty pathologists can meet successfully over 26 years, maintain a high state of engagement through each annual meeting, self-renew as a result of retirement or resignation, and provide a creative stimulus for highly productive academic careers.

Analyses of a matched sample show that workgroup emotional climate moderates the relationship between transformational/transactional leadership and workgroup innovation performance. Specifically, when the workgroup emotional climate is positive, transformational leadership is positively related to workgroup innovation performance, and transactional leadership is negatively related to workgroup innovation performance; however, when the workgroup emotional climate is negative, transformational leadership is negatively related to workgroup innovation performance, and transactional leadership is positively related to workgroup innovation performance. Corresponding managerial implications are offered.

Unlike autocratic decision-making, group voting leads to workgroups outperforming the control condition where cyberloafing could not be stopped. Additionally, only in the group voting regime did production levels of cyberloafers and non-loafers converge over time.

    2012-03-01

    Psychosocial safety climate (PSC) arises from workplace policies, practices, and procedures for the protection of worker psychological health and safety that are largely driven by management. Many work stress theories are based on the fundamental interaction hypothesis - that a high level of job demands (D) will lead to psychological distress and that this relationship will be offset when there are high job resources (R). However we proposed that this interaction really depends on the organizational context; in particular high levels of psychosocial safety climate will enable the safe utilization of resources to reduce demands. The study sample consisted of police constables from 23 police units (stations) with longitudinal survey responses at two time points separated by 14 months (Time 1, N=319, Time 2, N=139). We used hierarchical linear modeling to assess the effect of the proposed three-way interaction term (PSC×D×R) on change in workgroup distress variance over time. Specifically we confirmed the interaction between emotional demands and emotional resources (assessed at the individual level), in the context of unit psychosocial safety climate (aggregated individual data). As predicted, high emotional resources moderated the positive relationship between emotional demands and change in workgroup distress but only when there were high levels of unit psychosocial safety climate. Results were confirmed using a split-sample analysis. Results support psychosocial safety climate as a property of the organization and a target for higher order controls for reducing work stress. The 'right' climate enables resources to do their job.

    The réseau santé cadre de vie (health and living environment network) was created in 2007 by the Atelier Santé Ville (Urban Health Workgroup) with the support of the CUCS in a run-down residential area of Marseille. Its aim is to improve the health of residents living in the private jointly-owned property of Kallisté by acting on factors determining lifestyle practices and the living environment. With the help of associations and institutions involved in the local network, a range of activities targeting local residents have been developed to promote access to healthcare and prevention and improve the living environment. The success of the project can be largely attributed to the involvement of the local social centre and institutional support. The development and continuity of cooperation (particularly between housing professionals and healthcare professionals) remain significant challenges in the effort to ensure the coherence and efficiency of the project.

    Since 1990s, genetically modified crops have developed rapidly and the genetically modified foods have entered the view and daily life of the common consumers. In the point view of consumers, it is a quite easy task to label the genetically modified foods to define their identities, provide consumers with right to know and make it convenient for customer service tracking and risk evaluation. However, it is always difficult for the world-level experts and scholars and till now they have not managed to develop an agreed and feasible labeling plan. Therefore, the paper made analysis and summary for this issue.%20世纪90年代以来,转基因作物发展迅猛,转基因食品已进入普通消费者的视野和生活。对转基因食品进行标识以亮明身份,既满足消费者的知情权,同时也便于售后跟踪和风险评估。这个在普通消费者看来非常简单的问题至今也没能拿出统一、可行的标识方案。笔者对这一问题进行初步的辨析和综述。

    To evaluate the evidence basis of single-domain cognitive tests frequently used by behavioral neurologists in an effort to improve the quality of clinical cognitive assessment. Behavioral Neurology Section members of the American Academy of Neurology were surveyed about how they conduct clinical cognitive testing, with a particular focus on the Neurobehavioral Status Exam (NBSE). In contrast to general screening cognitive tests, an NBSE consists of tests of individual cognitive domains (e.g., memory or language) that provide a more comprehensive diagnostic assessment. Workgroups for each of 5 cognitive domains (attention, executive function, memory, language, and spatial cognition) conducted evidence-based reviews of frequently used tests. Reviews focused on suitability for office-based clinical practice, including test administration time, accessibility of normative data, disease populations studied, and availability in the public domain. Demographic and clinical practice data were obtained from 200 respondents who reported using a wide range of cognitive tests. Based on survey data and ancillary information, between 5 and 15 tests in each cognitive domain were reviewed. Within each domain, several tests are highlighted as being well-suited for an NBSE. We identified frequently used single-domain cognitive tests that are suitable for an NBSE to help make informed choices about clinical cognitive assessment. Some frequently used tests have limited normative data or have not been well-studied in common neurologic disorders. Utilizing standardized cognitive tests, particularly those with normative data based on the individual's age and educational level, can enhance the rigor and utility of clinical cognitive assessment. © 2015 American Academy of Neurology.

    Accurate measurement of economic costs is prerequisite to progress in improving the care delivered to Americans during the last stage of life. The Robert Wood Johnson Excellence in End-of-Life Care national program assembled a Cost Accounting Workgroup to identify accurate and meaningful methods to measure palliative and end-of-life health care use and costs. Eight key issues were identified: (1) planning the cost analysis; (2) identifying the perspective for cost analysis; (3) describing the end-of-life care program; (4) identifying the appropriate comparison group; (5) defining the period of care to be studied; (6) identifying the units of health care services; (7) assigning monetary values to health care service units; and (8) calculating costs. Economic principles of cost measurement and cost measurement issues encountered by practitioners were reviewed and incorporated into a set of recommendations.

    2005-05-01

    Guidelines for design of clinical trials evaluating behavioral headache treatments were developed to facilitate production of quality research evaluating behavioral therapies for management of primary headache disorders. These guidelines were produced by a Workgroup of headache researchers under auspices of the American Headache Society. The guidelines are complementary to and modeled after guidelines for pharmacological trials published by the International Headache Society, but they address methodologic considerations unique to behavioral and other nonpharmacological treatments. Explicit guidelines for evaluating behavioral headache therapies are needed as the optimal methodology for behavioral (and other nonpharmacologic) trials necessarily differs from the preferred methodology for drug trials. In addition, trials comparing and integrating drug and behavioral therapies present methodological challenges not addressed by guidelines for pharmacologic research. These guidelines address patient selection, trial design for behavioral treatments and for comparisons across multiple treatment modalities (eg, behavioral vs pharmacologic), evaluation of results, and research ethics. Although developed specifically for behavioral therapies, the guidelines may apply to the design of clinical trials evaluating many forms of nonpharmacologic therapies for headache.

    2012-04-01

    The Group on Earth Observations (GEO) is coordinating efforts to build a Global Earth Observation System of Systems, or GEOSS. As part of a strategy to increase the involvement of the science and technology community in GEOSS, both as users and developers of GEOSS itself, GEO decided to develop a GEO label concept related to the scientific relevance, quality, acceptance and societal needs for services and data sets of GEOSS. The development of a GEO label is included in the GEO work plan and several projects address the challenges of developing a GEO label concept. Within the different projects developing the GEO label, various perspectives and approaches are being applied. In order to arrive at a generally accepted GEO label concept, a common understanding and basic knowledge of labeling is necessary. Assessment of quality of internationally standardized Earth observation data products implies possible certification. A general understanding of the framework for international standards and certification will also contribute to a more coherent discussion and more efficient development of a GEO label. We will describe the general labeling and certification framework emphasizing the relation to the three elements of the GEO label: quality, user acceptance and relevance. Based on a survey of international labels done by the EGIDA project, we have analyzed the legal framework and organization of labels and certification. We will discuss the frameworks for certification, user ratings, registration and analysis of user requirements. Quality assessment is a particular focus of the analysis and is based on the work done by the GeoViQua project. A GEO label will function both as a data distribution strategy and as a general management system for data. Through a label users can compare different data sets and get access to more information about the relevant data, including quality. A label will provide traceability of data both in the interest of users as well as data

    The authors conducted a cross-cultural longitudinal investigation of the effects of culture (individualism-collectivism dichotomy) on group characteristics (functional heterogeneity, preference for teamwork, group potency, outcome expectation) and on performance of 83 work groups performing 2 decision-making tasks over a 15-week period. The individualists (U.S. students) reported higher levels of functional heterogeneity and group potency and attained higher levels of group performance than did the collectivists (Korean students). In addition, culture and time interacted to influence ratings of group potency and outcome expectation. The difference in ratings of group potency between individualists and collectivists increased over time. Outcome expectation was greater among the collectivists in Time 1 and among the individualists in Time 2. The authors discuss implications for future cross-cultural group research and international management.

    2012-10-01

    The present paper evaluates the effect of transformational leadership on job satisfaction and change commitment along with their interconnected effects (mediation) on cooperative conflict resolution (management) in customer service activities in Taiwan. The multi-source samples consist of data from personnel serving at customer centers (workgroups), such as phone service personnel, customer representatives, financial specialists, and front-line salespeople. An empirical study was carried out using a multiple mediation procedure incorporating boot-strapping techniques and PRODCLIN2 with structural equation modeling (SEM) analysis. The results indicate that the main effect of the leadership style on cooperative conflict resolution is mediated by change commitment and job satisfaction.

  16. Ethics in occupational health: deliberations of an international workgroup addressing challenges in an African context

    Science.gov (United States)

    2014-01-01

    Background International codes of ethics play an important role in guiding professional practice in developing countries. In the occupational health setting, codes developed by international agencies have substantial import on protecting working populations from harm. This is particularly so under globalisation which has transformed processes of production in fundamental ways across the globe. As part of the process of revising the Ethical Code of the International Commission on Occupational Health, an Africa Working Group addressed key challenges for the relevance and cogency of an ethical code in occupational health for an African context through an iterative consultative process. Discussion Firstly, even in the absence of strong legal systems of enforcement, and notwithstanding the value of legal institutionalisation of ethical codes, guidelines alone may offer advantageous routes to enhancing ethical practice in occupational health. Secondly, globalisation has particularly impacted on health and safety at workplaces in Africa, challenging occupational health professionals to be sensitive to, and actively redress imbalance of power. Thirdly, the different ways in which vulnerability is exemplified in the workplace in Africa often places the occupational health professional in invidious positions of Dual Loyalty. Fourth, the particular cultural emphasis in traditional African societies on collective responsibilities within the community impacts directly on how consent should be sought in occupational health practice, and how stigma should be dealt with, balancing individual autonomy with ideas of personhood that are more collective as in the African philosophy of ubuntu. To address stigma, practitioners need to be additionally sensitive to how power imbalances at the workplace intersect with traditional cultural norms related to solidarity. Lastly, particularly in the African context, the inseparability of workplace and community means that efforts to address

    2017-06-01

    Convolutional Neural Networks (ConvNets) have achieved excellent recognition performance in various visual recognition tasks. A large labeled training set is one of the most important factors for its success. However, it is difficult to collect sufficient training images with precise labels in some domains such as apparent age estimation, head pose estimation, multi-label classification and semantic segmentation. Fortunately, there is ambiguous information among labels, which makes these tasks different from traditional classification. Based on this observation, we convert the label of each image into a discrete label distribution, and learn the label distribution by minimizing a Kullback-Leibler divergence between the predicted and ground-truth label distributions using deep ConvNets. The proposed DLDL (Deep Label Distribution Learning) method effectively utilizes the label ambiguity in both feature learning and classifier learning, which help prevent the network from over-fitting even when the training set is small. Experimental results show that the proposed approach produces significantly better results than state-of-the-art methods for age estimation and head pose estimation. At the same time, it also improves recognition performance for multi-label classification and semantic segmentation tasks.

  5. Photoaffinity Labeling of Plasma Proteins

    Directory of Open Access Journals (Sweden)

    Masaki Otagiri

    2013-11-01

    Full Text Available Photoaffinity labeling is a powerful technique for identifying a target protein. A high degree of labeling specificity can be achieved with this method in comparison to chemical labeling. Human serum albumin (HSA and α1-acid glycoprotein (AGP are two plasma proteins that bind a variety of endogenous and exogenous substances. The ligand binding mechanism of these two proteins is complex. Fatty acids, which are known to be transported in plasma by HSA, cause conformational changes and participate in allosteric ligand binding to HSA. HSA undergoes an N-B transition, a conformational change at alkaline pH, that has been reported to result in increased ligand binding. Attempts have been made to investigate the impact of fatty acids and the N-B transition on ligand binding in HSA using ketoprofen and flunitrazepam as photolabeling agents. Meanwhile, plasma AGP is a mixture of genetic variants of the protein. The photolabeling of AGP with flunitrazepam has been utilized to shed light on the topology of the protein ligand binding site. Furthermore, a review of photoaffinity labeling performed on other major plasma proteins will also be discussed. Using a photoreactive natural ligand as a photolabeling agent to identify target protein in the plasma would reduce non-specific labeling.

    Yang, Yi-Feng

    2014-02-01

    This paper discusses the effects of transformational leadership on cooperative conflict resolution (management) by evaluating several alternative models related to the mediating role of job satisfaction and change commitment. Samples of data from customer service personnel in Taiwan were analyzed. Based on the bootstrap sample technique, an empirical study was carried out to yield the best fitting model. The procedure of hierarchical nested model analysis was used, incorporating the methods of bootstrapping mediation, PRODCLIN2, and structural equation modeling (SEM) comparison. The analysis suggests that leadership that promotes integration (change commitment) and provides inspiration and motivation (job satisfaction), in the proper order, creates the means for cooperative conflict resolution.

  15. 99mTc: Labeling Chemistry and Labeled Compounds

    Science.gov (United States)

    Alberto, R.; Abram, U.

    This chapter reviews the radiopharmaceutical chemistry of technetium related to the synthesis of perfusion agents and to the labeling of receptor-binding biomolecules. To understand the limitations of technetium chemistry imposed by future application of the complexes in nuclear medicine, an introductory section analyzes the compulsory requirements to be considered when facing the incentive of introducing a novel radiopharmaceutical into the market. Requirements from chemistry, routine application, and market are discussed. In a subsequent section, commercially available 99mTc-based radiopharmaceuticals are treated. It covers the complexes in use for imaging the most important target organs such as heart, brain, or kidney. The commercially available radiopharmaceuticals fulfill the requirements outlined earlier and are discussed with this background. In a following section, the properties and perspectives of the different generations of radiopharmaceuticals are described in a general way, covering characteristics for perfusion agents and for receptor-specific molecules. Technetium chemistry for the synthesis of perfusion agents and the different labeling approaches for target-specific biomolecules are summarized. The review comprises a general introduction to the common approaches currently in use, employing the N x S4-x , [3+1] and 2-hydrazino-nicotinicacid (HYNIC) method as well as more recent strategies such as the carbonyl and the TcN approach. Direct labeling without the need of a bifunctional chelator is briefly reviewed as well. More particularly, recent developments in the labeling of concrete targeting molecules, the second generation of radiopharmaceuticals, is then discussed and prominent examples with antibodies/peptides, neuroreceptor targeting small molecules, myocardial imaging agents, vitamins, thymidine, and complexes relevant to multidrug resistance are given. In addition, a new approach toward peptide drug development is described. The section

    Biological radioisotope studies suffer from a lack of sensitive measurement techniques and therefore traditionally require large amounts of labeled material to produce a measurable signal. Such quantities of materials are often significantly higher than naturally-occurring levels preventing these studies from replicating physiological conditions. AMS affords the sensitivity necessary to perform biological radioisotope studies with low levels of labeled material that preserve physiological conditions. The choice of labeled material can substantially affect the ease of interpretation and comprehensiveness of these studies. Here, the benefits and limitations of whole-cell labeling with {sup 14}C-glucose and targeted pathway labeling with {sup 14}C-nicotinic acid are discussed and compared.

    This comprehensive report for the Swiss Federal Office of Energy (SFOE) presents a possible course of action to be taken to provide a means of declaring the sources of electrical power, as is foreseen in the draft of new Swiss electricity market legislation. The report presents the basic ideas behind the idea and defines the terms used such as labelling, certificates and declarations. Also, the legal situation in the European Union and in Switzerland is examined and a quantitative overview of electricity production and consumption is presented. Suggestions for a labelling scheme are made and some of the problems to be expected are looked at. The report also presents a series of examples of labelling schemes already implemented in other countries, such as Austria, Great Britain, Sweden and Germany. Tradable certificates and tracking systems are discussed as are initial quality labels like the Swiss 'Naturemade' label for green power. A concrete recommendation for the declaration and labelling of electricity in Switzerland is presented and various factors to be considered such as import/export, pumped storage, distribution losses, small-scale producers as well as the time-scales for introduction are discussed.

    A capacitive label reader includes an outer ring transmitting portion, an inner ring transmitting portion, and a plurality of insulated receiving portions. A label is the mirror-image of the reader except that identifying portions corresponding to the receiving portions are insulated from only one of two coupling elements. Positive and negative pulses applied, respectively, to the two transmitting rings biased a CMOS shift register positively to either a 1 or 0 condition. The output of the CMOS may be read as an indication of the label.

  8. Information Measures of Degree Distributions with an Application to Labeled Graphs

    Energy Technology Data Exchange (ETDEWEB)

    Joslyn, Cliff A.; Purvine, Emilie AH

    2016-01-11

    The problem of describing the distribution of labels over a set of objects is relevant to many domains. For example: cyber security, social media, and protein interactions all care about the manner in which labels are distributed among different objects. In this paper we present three interacting statistical measures on label distributions, inspired by entropy and information theory. Labeled graphs are discussed as a specific case of labels distributed over a set of edges. We describe a use case in cyber security using a labeled directed multi-graph of IPFLOW. Finally we show how these measures respond when labels are updated in certain ways.

  9. Reading the Small Print – Labelling Recommendations for Orthopaedic Implants

    Science.gov (United States)

    Haene, Roger A; Sandhu, Ranbir S; Baxandall, Richard

    2009-01-01

    INTRODUCTION There exist, currently, no clear guidelines regarding standards for surgical implant labelling. Dimensions of the laminar flow canopies in orthopaedic use fixes the distance at which implant labels can be read. Mistakes when reading the label on an implant box can pose health risks for patients, and financial consequences for medical institutions. SUBJECTS AND METHODS Using scientifically validated tools such as the Snellen Chart Formula, a theoretical minimum standard for text on implant labels was reached. This theoretical standard was then tested under real operating conditions. After discovering a minimum practical standard for implant labels, the authors then audited current labels in use on a wide range of orthopaedic implant packages. Furthermore, other non-text-related labelling problems were also noted. RESULTS There is a definite minimum standard which should be observed when implant labels are manufactured. Implants in current use bear labels on the packaging that are of an insufficient standard to ensure patient safety in theatre. CONCLUSIONS The authors have established text parameters that will increase the legibility of implant labels. In the interests of improving risk management in theatre, therefore, the authors propose a standard for orthopaedic implant labelling, and believe this will provide a useful foundation for further discussion between the orthopaedic community and implant manufacturers.

  17. Discussion in Postsecondary Classrooms

    Directory of Open Access Journals (Sweden)

    Curt Dudley-Marling

    2013-11-01

    Full Text Available Spoken language is, arguably, the primary means by which teachers teach and students learn. Much of the literature on language in classrooms has focused on discussion that is seen as both a method of instruction and a curricular outcome. While much of the research on discussion has focused on K-12 classrooms, there is also a body of research examining the efficacy of discussion in postsecondary settings. This article provides a review of this literature in order to consider the effect of discussion on student learning in college and university classrooms, the prevalence of discussion in postsecondary settings, and the quality of discussion in these settings. In general, the results of research on the efficacy of discussion in postsecondary settings are mixed. More seriously, researchers have not been explicit about the meaning of discussion and much of what is called discussion in this body of research is merely recitation with minimal levels of student participation. Although the research on discussion in college and university classrooms is inconclusive, some implications can be drawn from this review of the research including the need for future researchers to clearly define what they mean by “discussion.”

  6. Multi-label

    Directory of Open Access Journals (Sweden)

    Neda Abdelhamid

    2015-01-01

    Full Text Available Generating multi-label rules in associative classification (AC from single label data sets is considered a challenging task making the number of existing algorithms for this task rare. Current AC algorithms produce only the largest frequency class connected with a rule in the training data set and discard all other classes even though these classes have data representation with the rule’s body. In this paper, we deal with the above problem by proposing an AC algorithm called Enhanced Multi-label Classifiers based Associative Classification (eMCAC. This algorithm discovers rules associated with a set of classes from single label data that other current AC algorithms are unable to induce. Furthermore, eMCAC minimises the number of extracted rules using a classifier building method. The proposed algorithm has been tested on a real world application data set related to website phishing and the results reveal that eMCAC’s accuracy is highly competitive if contrasted with other known AC and classic classification algorithms in data mining. Lastly, the experimental results show that our algorithm is able to derive new rules from the phishing data sets that end-users can exploit in decision making.

  20. Quantitative proteomics using reductive dimethylation for stable isotope labeling.

    Science.gov (United States)

    Tolonen, Andrew C; Haas, Wilhelm

    2014-07-01

    Stable isotope labeling of peptides by reductive dimethylation (ReDi labeling) is a method to accurately quantify protein expression differences between samples using mass spectrometry. ReDi labeling is performed using either regular (light) or deuterated (heavy) forms of formaldehyde and sodium cyanoborohydride to add two methyl groups to each free amine. Here we demonstrate a robust protocol for ReDi labeling and quantitative comparison of complex protein mixtures. Protein samples for comparison are digested into peptides, labeled to carry either light or heavy methyl tags, mixed, and co-analyzed by LC-MS/MS. Relative protein abundances are quantified by comparing the ion chromatogram peak areas of heavy and light labeled versions of the constituent peptide extracted from the full MS spectra. The method described here includes sample preparation by reversed-phase solid phase extraction, on-column ReDi labeling of peptides, peptide fractionation by basic pH reversed-phase (BPRP) chromatography, and StageTip peptide purification. We discuss advantages and limitations of ReDi labeling with respect to other methods for stable isotope incorporation. We highlight novel applications using ReDi labeling as a fast, inexpensive, and accurate method to compare protein abundances in nearly any type of sample.

Previous work on map labeling has focused on the problem of placing maximal uniform, axis-aligned, disjoint rectangles on the plane so that each point feature to be labeled lies at the corner of one rectangle. Here, we consider a number of variants of the map labeling problem. We obtain three general types of results. First, we devise constant-factor polynomial-time-approximation algorithms for labeling point features by rectangular labels, where the feature may lie anywhere on the boundary of its label region and where labeling rectangles may be placed in any orientation. These results generalize to the case of elliptical labels. Secondly, we consider the problem of labeling a map consisting of disjoint rectilinear fine segments. We obtain constant-factor polynomial-time approximation algorithms for the general problem and an optimal algorithm for the special case where all segments are horizontal. Finally, we formulate a bicriteria version of the map-labeling problem and provide bicriteria polynomial- time approximation schemes for a number of such problems.

    Blood cell labeling can be considered a science in as far as it is based on precise knowledge and can be readily reproduced. This benchmark criterion is applied to all current cell labeling modalities and their relative merits and deficiencies are discussed. Mechanisms are given where they are known as well as labeling yields, label stability, and cell functionality. The focus is on the methodology and its suitability to the clinical setting rather than on clinical applications per se. Clinical results are cited only as proof of efficacy of the various methods. The emphasis is on technetium as the cell label, although comparisons are made between technetium and indium, and all blood cells are covered. 52 refs., 6 figs., 7 tabs.

  14. Towards Multi Label Text Classification through Label Propagation

    2012-06-01

    Full Text Available Classifying text data has been an active area of research for a long time. Text document is multifaceted object and often inherently ambiguous by nature. Multi-label learning deals with such ambiguous object. Classification of such ambiguous text objects often makes task of classifier difficult while assigning relevant classes to input document. Traditional single label and multi class text classification paradigms cannot efficiently classify such multifaceted text corpus. Through our paper we are proposing a novel label propagation approach based on semi supervised learning for Multi Label Text Classification. Our proposed approach models the relationship between class labels and also effectively represents input text documents. We are using semi supervised learning technique for effective utilization of labeled and unlabeled data for classification. Our proposed approach promises better classification accuracy and handling of complexity and elaborated on the basis of standard datasets such as Enron, Slashdot and Bibtex.

    2008-01-01

    Labels and tags are accompanying us in almost each moment of our life and everywhere we are going, in the form of electronic keys or money, or simply as labels on products we are buying in shops and markets. The label diffusion, rapidly increasing for logistic reasons in the actual global market, carries huge amount of information but it is demanding security and anti-fraud systems. The first crucial point, for the consumer and producer safety, is to ensure the authenticity of the labelled products with systems against counterfeiting and piracy. Recent anti-fraud techniques are based on a sophisticated use of physical effects, from holograms till magnetic resonance or tunnel transitions between atomic sublevels. In this paper we will discuss labels and anti-fraud technologies as a new and very promising research field for applied physics.

  20. Empowerment: a conceptual discussion.

    Science.gov (United States)

    Tengland, Per-Anders

    2008-06-01

    The concept of 'empowerment' is used frequently in a number of professional areas, from psychotherapy to social work. But even if the same term is used, it is not always clear if the concept denotes the same goals or the same practice in these various fields. The purpose of this paper is to clarify the discussion and to find a plausible and useful definition of the concept that is suitable for work in various professions. Several suggestions are discussed in the paper, for example control over life or health, autonomy, ability, self-efficacy, self-esteem, and freedom, and it is concluded that there are two plausible complementary uses, one as a goal and one as a process or approach. Empowerment as a goal is to have control over the determinants of one's quality of life, and empowerment as a process is to create a professional relation where the client or community takes control over the change process, determining both the goals of this process and the means to use.

    Quantitative proteomics is an important research field in post-genomics era. There are two strategies for proteome quantification: label-free methods and stable isotope labeling methods which have become the most important strategy for quantitative proteomics at present. In the past few years, a number of quantitative methods have been developed, which support the fast development in biology research. In this work, we discuss the progress in the stable isotope labeling methods for quantitative proteomics including relative and absolute quantitative proteomics, and then give our opinions on the outlook of proteome quantification methods.

  15. Algorithms for Labeling Focus Regions.

    Science.gov (United States)

    Fink, M; Haunert, Jan-Henrik; Schulz, A; Spoerhase, J; Wolff, A

    2012-12-01

    In this paper, we investigate the problem of labeling point sites in focus regions of maps or diagrams. This problem occurs, for example, when the user of a mapping service wants to see the names of restaurants or other POIs in a crowded downtown area but keep the overview over a larger area. Our approach is to place the labels at the boundary of the focus region and connect each site with its label by a linear connection, which is called a leader. In this way, we move labels from the focus region to the less valuable context region surrounding it. In order to make the leader layout well readable, we present algorithms that rule out crossings between leaders and optimize other characteristics such as total leader length and distance between labels. This yields a new variant of the boundary labeling problem, which has been studied in the literature. Other than in traditional boundary labeling, where leaders are usually schematized polylines, we focus on leaders that are either straight-line segments or Bezier curves. Further, we present algorithms that, given the sites, find a position of the focus region that optimizes the above characteristics. We also consider a variant of the problem where we have more sites than space for labels. In this situation, we assume that the sites are prioritized by the user. Alternatively, we take a new facility-location perspective which yields a clustering of the sites. We label one representative of each cluster. If the user wishes, we apply our approach to the sites within a cluster, giving details on demand.

    Full Text Available The widespread «off-label» drug use and the prescribing of unlicensed medicines in pediatric practice is a major health problem. The authors discuss actual regulatory and legal issues of «off-label» drug use in children in the US, Europe and Russia. The results of different population-based studies from many countries, showing the structure and frequency of «off-label» drug use in children, are summarized in this article. It is shown that such practice increases the risk of adverse drug reactions. The authors offer practical recommendations for a safer use of drugs in pediatric practice. The priority issue is conducting high quality clinical trials with the participation of children, improving national pharmacovigilance and the monitoring of off-label drug use, developing pediatric formularies, improving doctors’ knowledge and awareness of safety and efficacy of medicines in pediatric population.

    Malik, Sohail (Washington Univ., Seattle, WA (United States))

    1994-10-01

    A convenient method is described to label a local anesthetic, benzocaine, with tritium. The bromoester of para-aminobenzoic acid (PABA) was prepared from para-nitrotoluene and was reduced with tritium. The generation of isotopic hydrogen and labelling of benzocaine was achieved in one-step. A mixture of sodium borohydride (NaB[sup 3]H[sub 4]) with cobalt (II) chloride was used to generate tritium gas. 5% Pd/C was used as a catalyst. This constitutes the first report of tritium labelled benzocaine. (author).

    In simulating radiotherapy, the bone and trachea identified by plain X-P and the other organs, such as the esophagus and bladder, outlined by contrast medium have so far been used as labels. However, irradiation with a high therapeutic ratio is required for an intracorporeal insertion of artificial labels that are identified by X-ray fluoroscopy. For this purpose, metal clips and seed dummies are available, although they cause artifacts in CT scans. Therefore, the authors are using an acupuncture needle and lipiodol for tracing as new artificial labels, since both are identified by X-ray fluoroscopy and CT scan and create few artifacts.

  2. Homogeneous Biosensing Based on Magnetic Particle Labels

    KAUST Repository

    Schrittwieser, Stefan

    2016-06-06

    The growing availability of biomarker panels for molecular diagnostics is leading to an increasing need for fast and sensitive biosensing technologies that are applicable to point-of-care testing. In that regard, homogeneous measurement principles are especially relevant as they usually do not require extensive sample preparation procedures, thus reducing the total analysis time and maximizing ease-of-use. In this review, we focus on homogeneous biosensors for the in vitro detection of biomarkers. Within this broad range of biosensors, we concentrate on methods that apply magnetic particle labels. The advantage of such methods lies in the added possibility to manipulate the particle labels by applied magnetic fields, which can be exploited, for example, to decrease incubation times or to enhance the signal-to-noise-ratio of the measurement signal by applying frequency-selective detection. In our review, we discriminate the corresponding methods based on the nature of the acquired measurement signal, which can either be based on magnetic or optical detection. The underlying measurement principles of the different techniques are discussed, and biosensing examples for all techniques are reported, thereby demonstrating the broad applicability of homogeneous in vitro biosensing based on magnetic particle label actuation.

    A great increase in the installation of stand-alone PV systems for rural electrification is expected in Brazil for the next years due to a government program named Luz para Todos. However, there is a major concern for the quality of the equipment and systems to be acquired and installed, which led to an initiative, coordinated by INMETRO - Brazilian Institute for Metrology, Standardisation and Industrial Quality (Instituto Brasileiro de Metrologia, Normalizacao e Qualidade Industrial), joining several institutions to establish a programme for labelling these equipment. The adopted requirements are discussed in the present article. (author)

  5. Effects of directional and neutral category labels in bidimensional rule-learning problems.

    Science.gov (United States)

    Neumann, P G

    1974-07-01

    In bidimensional concept problems, the distinction between primary and complementary rule forms is, in some sense, a function of the directional nature of the sorting category labels. Primary rules are those rules which assign the TT class to the "positive" category. Complementary rule forms are obtained by reversing these category assignments. Instead of directional labels, neutral labels can be used. Reversing these labels creates no fundamental change in the solution of the problem. The present experiment investigates the effect of directional and neutral category labels in a design which incorporates all 12 problems defined by the combination of directional and neutral labels. Significant effects of labels on performance were obtained. Implications of these effects for hypotheses advanced by Seggie (1969), Peters and Denny (1971), and Bourne and Guy (1968) are discussed.

    With ever changing landscapes and environmental conditions due to human induced climate change, adaptability is imperative for the long-term success of facilities and Federal agency missions. To mitigate the effects of climate change, indicators such as above-ground biomass change must be identified to establish a comprehensive monitoring effort. Researching the varying effects of climate change on ecosystems can provide a scientific framework that will help produce informative, strategic and tactical policies for environmental adaptation. As a proactive approach to climate change mitigation, NASA tasked the Climate Change Adaptation Science Investigators Workgroup (CASI) to provide climate change expertise and data to Center facility managers and planners in order to ensure sustainability based on predictive models and current research. Generation of historical datasets that will be used in an agency-wide effort to establish strategies for climate change mitigation and adaptation at NASA facilities is part of the CASI strategy. Using time series of historical remotely sensed data is well-established means of measuring change over time. CASI investigators have acquired multispectral and hyperspectral optical and LiDAR remotely sensed datasets from NASA Earth Observation Satellites (including the International Space Station), airborne sensors, and astronaut photography using hand held digital cameras to create a historical dataset for the Johnson Space Center, as well as the Houston and Galveston area. The raster imagery within each dataset has been georectified, and the multispectral and hyperspectral imagery has been atmospherically corrected. Using ArcGIS for Server, the CASI-Regional Remote Sensing data has been published as an image service, and can be visualized through a basic web mapping application. Future work will include a customized web mapping application created using a JavaScript Application Programming Interface (API), and inclusion of the CASI data

    We present here a few basic proposals for algorithms and procedures for imaging the paediatric genitourinary tract based on initial discussion at a paediatric uroradiology symposium and proposals of the ESUR Paediatric Uroradiologic Guidelines Subcommittee. These recommendations were developed in the light of new knowledge that might influence existing guidelines. Regional, individual and local flexibility and variability should be preserved in order to make these recommendations applicable throughout Europe. They should help standardize dedicated imaging not only in terms of a quality measure to ensure state-of-the-art patient care, but also in forming a common basis for multi-institutional research. There is an urgent need for these guidelines in order to advance our understanding of the subject and to gain evidence and improve imaging efficacy. Our session worked towards establishing an agreement on imaging indications in common paediatric urological conditions, respecting the ALARA principle, and patient safety and care, and taking into account state of the art knowledge and efficacy aspects. We started the task with a reassessment of (1) imaging in urinary tract infection in infants and children, (2) postnatal imaging in mild-to-moderate neonatal hydronephrosis, (3) how to perform voiding cystourethrography, and (4) procedural recommendations for paediatric urosonography. This list is incomplete, and future recommendations will be developed, discussed and presented at forthcoming meetings. (orig.)

  12. Labelling analysis for ¹³C MFA using NMR spectroscopy.

    Jouhten, Paula; Maaheimo, Hannu

    2014-01-01

    NMR spectroscopy is an efficient method for analyzing (13)C labelling of cellular metabolites. The strength of it is especially the ability to provide direct quantitative positional information on the (13)C labelling status of carbon atoms in metabolites. NMR spectroscopic methods allow also for detection of contiguously (13)C-labelled fragments in the carbon backbones of the metabolites. Furthermore, the recent developments of NMR spectroscopy hardware have substantially improved the sensitivity of the methods. In this chapter we describe a method for analyzing the (13)C labelling of the biomass amino acids for metabolic flux analysis, sample preparation for NMR spectroscopy, acquiring and processing the NMR spectra, and extracting the (13)C labelling information from the NMR data. Different NMR methods are applied depending on the (13)C labelling strategy chosen. These strategies include uniform (13)C labelling, positional (13)C labelling, or a combination of both. Not only the preparation of sample for analysis of (13)C labelling in proteinogenic amino acids in biomass is described, but also the necessary modifications to the method when analysis of (13)C labelling in free metabolic intermediates is of interest. Finally the strategies for using the different NMR-detected (13)C labelling data in (13)C MFA are discussed.

    General consumer knowledge of and engagement with the production of food has declined resulting in increasing consumer uncertainty about, and sensitivity to, food risks. Emphasis is therefore placed on providing information for consumers to reduce information asymmetry regarding food risks, particularly through food labelling. This study examines the role of food labelling in influencing consumer perceptions of food risks. In-depth, 1-h interviews were conducted with 24 Australian consumers. Participants were recruited based on an a priori defined food safety risk scale, and to achieve a diversity of demographic characteristics. The methodological approach used, adaptive theory, was chosen to enable a constant interweaving of theoretical understandings and empirical data throughout the study. Participants discussed perceiving both traditional (food spoilage/microbial contamination) and modern (social issues, pesticide and 'chemical' contamination) risks as present in the food system. Food labelling was a symbol of the food system having managed traditional risks, and a tool for consumers to personally manage perceived modern risks. However, labelling also raised awareness of modern risks not previously considered. The consumer framing of risk presented demonstrates the need for more meaningful consumer engagement in policy decision making to ensure risk communication and management meet public expectations. This research innovatively identifies food labelling as both a symbol of, and a tool for, the management of perceived risks for consumers. Therefore it is imperative that food system actors ensure the authenticity and trustworthiness of all aspects of food labelling, not only those related to food safety.

    2005-12-15

    The term cell labelling is usually used in the context of labelled leukocytes for imaging inflammation and labelled platelets for imaging thrombosis. Erythrocyte labelling for in vitro measurements of red cell life span, in vivo measurements of splenic red cell pooling, radionuclide ventriculography and imaging sites of bleeding has developed rather separately and has a different history. Labelled platelets and leukocytes were originally developed for cell kinetic studies. Since the current-day applications of labelled platelets and leukocytes depend on a clear understanding of cell kinetics, these classical studies are important and relevant to the history of cell labelling.

    Of the different techniques of labelling liophylized human fibrinogen, the technique of mono-chloride with modified iodine was selected. The labelling of the molecule was performed in alkali media of buffalo glycine in which the solution of stable iodine will react as well as on a later stage will the radioactive isotope. The labelling processes which were undertaken with different activities had an efficiency of over 40%; when purification with resins amberlite was carried through, in none of the cases were the impurities over 5%. Daily controls till the seventh day showed that the average values of radiochemical purity decrease were lower than 1%. The specific activity as well as the concentration of I/sup 131/, the fibrinogen and other characteristics come up to the norms of the pharmacopoeia which are applied.

  7. Learning With Auxiliary Less-Noisy Labels.

    Obtaining a sufficient number of accurate labels to form a training set for learning a classifier can be difficult due to the limited access to reliable label resources. Instead, in real-world applications, less-accurate labels, such as labels from nonexpert labelers, are often used. However, learning with less-accurate labels can lead to serious performance deterioration because of the high noise rate. Although several learning methods (e.g., noise-tolerant classifiers) have been advanced to increase classification performance in the presence of label noise, only a few of them take the noise rate into account and utilize both noisy but easily accessible labels and less-noisy labels, a small amount of which can be obtained with an acceptable added time cost and expense. In this brief, we propose a learning method, in which not only noisy labels but also auxiliary less-noisy labels, which are available in a small portion of the training data, are taken into account. Based on a flipping probability noise model and a logistic regression classifier, this method estimates the noise rate parameters, infers ground-truth labels, and learns the classifier simultaneously in a maximum likelihood manner. The proposed method yields three learning algorithms, which correspond to three prior knowledge states regarding the less-noisy labels. The experiments show that the proposed method is tolerant to label noise, and outperforms classifiers that do not explicitly consider the auxiliary less-noisy labels.

  12. Connected Component Labeling Using Components Neighbors-Scan Labeling Approach

    Directory of Open Access Journals (Sweden)

    Akmal Rakhmadi

    2010-01-01

    Full Text Available Problem statement: Many approaches have been proposed in previous such as the classic sequential connected components labeling algorithm which is relies on two subsequent raster-scans of a binary image. This method produced good performance in terms of accuracy, but because of the implementation of the image processing systems now requires faster process of the computer, the speed of this technique’s process has become an important issue. Approach: A computational approach, called components neighbors-scan labeling algorithm for connected component labeling was presented in this study. This algorithm required scanning through an image only once to label connected components. The algorithm started by scanning from the head of the component’s group, before tracing all the components neighbors by using the main component’s information. This algorithm had desirable characteristics, it is simple while promoted accuracy and low time consuming. By using a table of components, this approach also gave other advantages as the information for the next higher process. Results: The approach had been tested with a collection of binary images. In practically all cases, the technique had successfully given the desired result. Averagely, from the results the algorithm increased the speed around 67.4% from the two times scanning method. Conclusion: Conclusion from the comparison with the previous method, the approach of components neighbors-scan for connected component labeling promoted speed, accuracy and simplicity. The results showed that the approach has a good performance in terms of accuracy, the time consumed and the simplicity of the algorithm.

    2016-01-01

    The detection techniques used in biosensors can be broadly classified into label-based and label-free. Label-based detection relies on the specific properties of labels for detecting a particular target. In contrast, label-free detection is suitable for the target molecules that are not labeled or the screening of analytes which are not easy to tag. Also, more types of label-free biosensors have emerged with developments in biotechnology. The latest developed techniques in label-free biosensors, such as field-effect transistors-based biosensors including carbon nanotube field-effect transistor biosensors, graphene field-effect transistor biosensors and silicon nanowire field-effect transistor biosensors, magnetoelastic biosensors, optical-based biosensors, surface stress-based biosensors and other type of biosensors based on the nanotechnology are discussed. The sensing principles, configurations, sensing performance, applications, advantages and restriction of different label-free based biosensors are considered and discussed in this review. Most concepts included in this survey could certainly be applied to the development of this kind of biosensor in the future.

  15. Food quality labels from the producers’ perspective

    2016-09-01

    Full Text Available The paper deals with analysing the food producer attitudes towards quality labels. The Klasa label, as the most known and the most frequently used food quality label in the Czech Republic, have become the subject of investigation. The aim of the research was to identify the benefits and problems arising from the certification process and the label use. Primary data were collected in online survey based on standardized questionnaire. In census, 86 respondents from the total 218 producers with the Klasa label in the Czech Republic completed the questionnaire. The most of producers (72% have a longer experience with the label, they are using the label for more than four years. The producers’ expectations from the label were fulfilled only partially. A poor state marketing support and missing marketing strategy were identified as general problems of the label. Specific perceived problems are formalities connected with the certification process and certification of poor-quality products. Correlation analysis, t-test and Pearson chi-square test were calculated to discover relations between variables. The results of the study can be beneficial to both, food producers as well as administrator of the label. Identified problems could help them to improve marketing strategy of the label in order to manage the label in effective way and use all benefits arising from the certification. Administrator of the label should make the certification process more effective and transparent, promotion should be focused on the explanation to consumers what the Klasa label guarantees.

  1. Conversational Markers of Constructive Discussions

    CERN Document Server

    Niculae, Vlad

    2016-01-01

    Group discussions are essential for organizing every aspect of modern life, from faculty meetings to senate debates, from grant review panels to papal conclaves. While costly in terms of time and organization effort, group discussions are commonly seen as a way of reaching better decisions compared to solutions that do not require coordination between the individuals (e.g. voting)---through discussion, the sum becomes greater than the parts. However, this assumption is not irrefutable: anecdotal evidence of wasteful discussions abounds, and in our own experiments we find that over 30% of discussions are unproductive. We propose a framework for analyzing conversational dynamics in order to determine whether a given task-oriented discussion is worth having or not. We exploit conversational patterns reflecting the flow of ideas and the balance between the participants, as well as their linguistic choices. We apply this framework to conversations naturally occurring in an online collaborative world exploration ga...

  2. The Effect of Labelling Practices in an Adolescent Facility

    Directory of Open Access Journals (Sweden)

    TRUDY RUDGE

    2009-04-01

    Full Text Available This paper presents and discusses the implications of labelling for patients who are a part of diagnostic group. Nurses not only allocate patient groups to a ‘bed space’ according to their illness, but they also allocate the individual by their past history, as well as by that patient’s previous level of surveillance, giving the act of labelling not only a structuring effect on patient care and diagnosis, but also a historicity. These beliefs are unthinkingly applied to both cohort and individual patient. The outcomes of such a practice led to group distinctions bestowed upon individuals regardless of whether such classification and organisation fit the patient or not. The effect of labelling left patients cared for the same way regardless of individual differences and left nurses relying on indirect mechanisms of control to look after these patients.

  3. Data-Parallel Mesh Connected Components Labeling and Analysis

    Harrison, Cyrus; Childs, Hank; Gaither, Kelly

    2011-04-10

    We present a data-parallel algorithm for identifying and labeling the connected sub-meshes within a domain-decomposed 3D mesh. The identification task is challenging in a distributed-memory parallel setting because connectivity is transitive and the cells composing each sub-mesh may span many or all processors. Our algorithm employs a multi-stage application of the Union-find algorithm and a spatial partitioning scheme to efficiently merge information across processors and produce a global labeling of connected sub-meshes. Marking each vertex with its corresponding sub-mesh label allows us to isolate mesh features based on topology, enabling new analysis capabilities. We briefly discuss two specific applications of the algorithm and present results from a weak scaling study. We demonstrate the algorithm at concurrency levels up to 2197 cores and analyze meshes containing up to 68 billion cells.

    2011-01-01

    In 2007, Tacoma-Pierce County Health Department launched a restaurant menu labeling project called SmartMenu. The objective was to recruit locally owned restaurants to voluntarily post basic nutrition information on their menus or menu boards. Participating restaurants submitted recipes to an independent contractor for nutritional analysis and agreed to post calorie, fat, carbohydrate, and sodium values on new menus within 90 days of receiving results. Vigorous recruitment efforts by the Health Department between June 2007 and September 2008 included free advertising, consultation with a Registered Dietitian, and free nutritional analysis. By the end of 2008, a total of 24 restaurants participated in the program. Significant barriers to participation included infrequent use of standardized recipes, perceived business risk of labeling, and low perceived customer demand for nutrition information. Key program elements, recruitment strategies, and costs are discussed. Results have important implications for future efforts to increase the adoption of menu labeling by locally owned and operated restaurants.

The labeling method is based on strain-promoted alkyne-azide cycloaddition (SPAAC) and strain-promoted inverse-electron-demand Diels-Alder cycloaddition (SPIEDAC) reactions, in which noncanonical amino acids (ncAAs) bearing ring-strained alkynes or alkenes react, respectively, with dyes containing azide or tetrazine groups. To introduce ncAAs site specifically into a protein of interest (POI), we use genetic code expansion technology. The protocol can be described as comprising two steps. In the first step, an Amber stop codon is introduced--by site-directed mutagenesis--at the desired site on the gene encoding the POI. This plasmid is then transfected into mammalian cells, along with another plasmid that encodes an aminoacyl-tRNA synthetase/tRNA (RS/tRNA) pair that is orthogonal to the host's translational machinery. In the presence of the ncAA, the orthogonal RS/tRNA pair specifically suppresses the Amber codon by incorporating the ncAA into the polypeptide chain of the POI. In the second step, the expressed POI is labeled with a suitably reactive dye derivative that is directly supplied to the growth medium. We provide a detailed protocol for using commercially available ncAAs and dyes for labeling the insulin receptor, and we discuss the optimal surface-labeling conditions and the limitations of labeling living mammalian cells. The protocol involves an initial cloning step that can take 4-7 d, followed by the described transfections and labeling reaction steps, which can take 3-4 d.

    Full Text Available Este artigo busca debater alguns trabalhos para os quais o sucesso na aprendizagem da leitura e escrita deve ter como base principal a consciência fonológica. Assim, do "Relatório final do grupo de trabalho alfabetização infantil: os novos caminhos", publicado pela Câmara dos Deputados em 2003, questionaremos pontos específicos, tais como a metodologia utilizada e o conseqüente tratamento de higienização dos dados, a relação fonema/grafema e a noção "chave" de consciência fonológica como fonte do (insucesso da leitura e escrita. Debateremos ainda trabalhos nos quais está subjacente a busca de um "estágio ideal" de ligação entre consciência, memória e aquisição da escrita. Os autores também evocam a importância da consciência fonológica para a aquisição de regras ortográficas e apontam a existência de um sujeito consciente que evolui em estágios de desenvolvimento. A partir de nosso campo de pesquisa, qual seja, o da aquisição de linguagem, e questionando e nos contrapondo à metodologia de seleção de dados estatisticamente relevantes por meio do método experimental, buscaremos mostrar, mediante a análise de erros singulares, que a relação entre sujeito e língua não pode ser pautada por uma análise metalingüística, sob pena de perder-se a singularidade do sujeito. Desse modo, argumentamos que, ao largo das competências e habilidades que o aluno, segundo aqueles estudos, deve desenvolver/adquirir por meio do defendido método fônico, há desde sempre uma língua que, em seu funcionamento simbólico, enreda o sujeito em suas tramas.This article seeks to discuss some works to which the success in learning to read and write must have as its main foundation the phonological awareness.

    The specifically synthesized and selected carbon dots of relatively high fluorescence quantum yields were evaluated in their fluorescence labeling of cells. For the cancer cell lines, the cellular uptake of the carbon dots was generally efficient, resulting in the labeling of the cells with bright fluorescence emissions for both one- and two-photon excitations from predominantly the cell membrane and cytoplasm. In the exploration on labeling the live stem cells, the cellular uptake of the carbon dots was relatively less efficient, though fluorescence emissions could still be adequately detected in the labeled cells, with the emissions again predominantly from the cell membrane and cytoplasm. This combined with the observed more efficient internalization of the same carbon dots by the fixed stem cells might suggest some significant selectivity of the stem cells toward surface functionalities of the carbon dots. The needs and possible strategies for more systematic and comparative studies on the fluorescence labeling of different cells, including especially live stem cells, by carbon dots as a new class of brightly fluorescent probes are discussed.

  9. Preparation of Radiopharmaceuticals Labeled with Metal Radionuclides

    Energy Technology Data Exchange (ETDEWEB)

    Welch, M.J.

    2012-02-16

    The overall goal of this project was to develop methods for the production of metal-based radionuclides, to develop metal-based radiopharmaceuticals and in a limited number of cases, to translate these agents to the clinical situation. Initial work concentrated on the application of the radionuclides of Cu, Cu-60, Cu-61 and Cu-64, as well as application of Ga-68 radiopharmaceuticals. Initially Cu-64 was produced at the Missouri University Research Reactor and experiments carried out at Washington University. A limited number of studies were carried out utilizing Cu-62, a generator produced radionuclide produced by Mallinckrodt Inc. (now Covidien). In these studies, copper-62-labeled pyruvaldehyde Bis(N{sup 4}-methylthiosemicarbazonato)-copper(II) was studied as an agent for cerebral myocardial perfusion. A remote system for the production of this radiopharmaceutical was developed and a limited number of patient studies carried out with this agent. Various other copper radiopharmaceuticals were investigated, these included copper labeled blood imaging agents as well as Cu-64 labeled antibodies. Cu-64 labeled antibodies targeting colon cancer were translated to the human situation. Cu-64 was also used to label peptides (Cu-64 octriatide) and this is one of the first applications of a peptide radiolabeled with a positron emitting metal radionuclide. Investigations were then pursued on the preparation of the copper radionuclides on a small biomedical cyclotron. A system for the production of high specific activity Cu-64 was developed and initially the Cu-64 was utilized to study the hypoxic imaging agent Cu-64 ATSM. Utilizing the same target system, other positron emitting metal radionuclides were produced, these were Y-86 and Ga-66. Radiopharmaceuticals were labeled utilizing both of these radionuclides. Many studies were carried out in animal models on the uptake of Cu-ATSM in hypoxic tissue. The hypothesis is that Cu-ATSM retention in vivo is dependent upon the

    Oliphant, Carrie S; Owens, Ryan E; Bolorunduro, Oluwaseyi B; Jha, Sunil K

    2016-10-01

    Ivabradine is a unique medication recently approved in the USA for the treatment of select heart failure patients. It was first approved for use in several countries around the world over a decade ago as an anti-anginal agent, with subsequent approval for use in heart failure patients. Since ivabradine has selective activity blocking the I f currents in the sinus node, it can reduce heart rate without appreciable effects on blood pressure. Given this heart-rate-specific effect, it has been investigated in many off-label indications as an alternative to traditional heart-rate-reducing medications such as beta blockers and calcium channel blockers. We conducted searches of PubMed and Google Scholar for ivabradine, heart failure, HFrEF, HFpEF, angina, coronary artery disease, inappropriate sinus tachycardia, postural orthostatic hypotension, coronary computed tomography angiography and atrial fibrillation. We reviewed and included studies, case reports, and case series published between 1980 and June 2016 if they provided information relevant to the practicing clinician. In many cases, larger clinical trials are needed to solidify the benefit of ivabradine, although studies indicate benefit in most therapeutic areas explored to date. The purpose of this paper is to review the current labeled and off-label uses of ivabradine, with a focus on clinical trial data.

    Full Text Available An antimagic labeling of a graph with q edges is a bijection from the set of edges to the set of positive integers {1,2,...,q} such that all vertex weights are pairwise distinct, where the vertex weight of a vertex is the sum of the labels of all the edges incident with that vertex. A graph is antimagic if it has an antimagic labeling. In this paper we construct antimagic labeling for the family of generalized sausage graphs.

    2015-08-01

    Various alternative methods are being used in many medical colleges to reinforce didactic lectures in physiology. Small group teaching can take on a variety of different tasks such as problem-solving, role play, discussions, brainstorming, and debate. Research has demonstrated that group discussion promotes greater synthesis and retention of materials. The aims of this study were to adopt a problem-solving approach by relating basic sciences with the clinical scenario through self-learning. To develop soft skills, to understand principles of group dynamics, and adopt a new teaching learning methodology. Experimental study design was conducted in Phase I 1(st) year medical students of 2014-2015 batch (n = 120). On the day of the session, the students were grouped into small groups (15 each). The session started with the facilitator starting off the discussion. Feedback forms from five students in each group was taken (n = 40). A five point Likert scale was used ranging from strongly agree to strongly disagree. Data were analyzed using IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp. Our results show that 70% of the students opined that small group discussion were interactive, friendly, innovative, built interaction between teacher and student. Small group discussion increased their thought process and helped them in better communication. The small group discussion was interactive, friendly, and bridged the gap between the teacher and student. The student's communication skills are also improved. In conclusion, small group discussion is more effective than the traditional teaching methods.

  18. Labeling nuclear DNA using DAPI.

    Science.gov (United States)

    Chazotte, Brad

    2011-01-01

    A number of fluorescent stains are available that label DNA and allow easy visualization of the nucleus in interphase cells and chromosomes in mitotic cells, including Hoechst, 4',6-diamidino-2-phenylindole (DAPI), ethidium bromide, propidium iodide, and acridine orange. Although not as bright as the vital Hoechst stains for DNA, DAPI has greater photostability. It is believed that DAPI associates with the minor groove of double-stranded DNA, with a preference for the adenine-thymine clusters. Cells must be permeabilized and/or fixed for DAPI to enter the cell and to bind DNA. Fluorescence increases approximately 20-fold when DAPI is bound to double-stranded DNA. This protocol describes the use of DAPI to label nuclear DNA of cells grown in culture.

  19. Tissue Specific Labeling in Proteomics

    Directory of Open Access Journals (Sweden)

    Evelyn Ramberger

    2017-07-01

    Full Text Available Mass spectrometry-based proteomics is a powerful tool for identifying and quantifying proteins in biological samples. While it is routinely used for the characterization of simple cell line systems, the analysis of the cell specific proteome in multicellular organisms and tissues poses a significant challenge. Isolating a subset of cells from tissues requires mechanical and biochemical separation or sorting, a process which can alter cellular signaling, and thus, the composition of the proteome. Recently, several approaches for cell selective labeling of proteins, that include bioorthogonal amino acids, biotinylating enzymes, and genetic tools, have been developed. These tools facilitate the selective labeling of proteins, their interactome, or of specific cell types within a tissue or an organism, while avoiding the difficult and contamination-prone biochemical separation of cells from the tissue. In this review, we give an overview of existing techniques and their application in cell culture models and whole animals.

    Rembert, Ron B.

    1995-01-01

    For Socrates, as he appears in Plato's dialogues, the process of discussion is essential for preparing human beings to lead a moral life. Only through discussion, Socrates maintains, can we be led to an understanding of such concepts as wisdom, courage and justice. The author of this article believes that the Socratic notion of the moral value of discussion is still valid. In support of this view, he examines two recent works: Dialogues on Moral Education by John Wilson and Barbara Cowell, and Moral Education, Secular and Religious by John L. Elias. Finally, the author suggests how the Socratic concept of dialogue might be used in moral education today.

    Relaxation labelling is an optimization technique used in many fields to solve constraint satisfaction problems. The algorithm finds a combination of values for a set of variables such that satisfies -to the maximum possible degree- a set of given constraints. This paper describes some experiments performed applying it to POS tagging, and the results obtained. It also ponders the possibility of applying it to word sense disambiguation.

    Yuan ZHANG; Yuan YUAN; Changsheng LIU

    2008-01-01

    A novel surface treatment method using 3-aminopropyltriethoxysilane (AMPTES), was developed to immobilize the fluorescein molecule on nano-HAP (nanometer hydroxyapatite) powders. By pretreating the nano-HAP powders surface with AMPTES, fluorescein, chosen on the basis of the chemical structure of the nano- HAP powders, could be bound to the nano-HAP powders surface. The chemical compositions of nano-HAP before and after being labeled were characterized by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The morphology, phase composition, and the fluorescence characteristics of the nano-HAP powders with and without staining were also investigated. The FTIR and XPS results revealed that fiuorescein had been successfully immobilized on the surface of AMPTES-bound nano-HAP powders via the acylamide bond formation between the -COOH of fluorescein and the -NH2 of AMPTES. The labeled nano-HAP powders possessed strong fluorescent intensity with a little deviation from the maximum emission wavelength of fluorescein. But the morphology and phase composition had no obvious alteration. Under fluorescence microscopy, the labeled nano-HAP powders., even after 24 h cell incubation, exhibited strong fluorescence.

    2010-01-01

    This research sought to determine how often nutrition marketing is used on labels of foods that are high in saturated fat, sodium, and/or sugar. All items packaged with food labels (N = 56,900) in all 6 grocery stores in Grand Forks, ND were surveyed. Marketing strategy, nutrient label information, if the product was fruit/or milk based, and target age. Frequency distributions were computed. Forty-nine percent of all products contained nutrition marketing and of those, 48% had both nutrition marketing and were high in saturated fat, sodium and/or sugar (11%, 17%, and 31% respectively). Seventy-one percent of products marketed to children had nutrition marketing. Of those, 59% were high in saturated fat, sodium and/or sugar content, with more than half being high in sugar. The most commonly used nutrition marketing statements were "good source of calcium", "reduced/low/fat free", and "food company's health symbol". Nutrition marketing is commonly used on products high in saturated fat, sodium and/or sugar and is more often used on products marketed toward children than products marketed toward adults. Current food industry symbols may not be helping consumers select foods low in saturated fat, sodium or sugar. Published by Elsevier Inc.

    2014-07-01

    Accurate and easy-to-understand nutrition labeling is a worthy public health goal that should be considered an important strategy among many to address obesity and poor diet. Updating the Nutrition Facts Panel on packaged foods, developing a uniform front-of-package labeling system and providing consumers with nutrition information on restaurant menus offer important opportunities to educate people about food's nutritional content, increase awareness of reasonable portion sizes and motivate consumers to make healthier choices. The aims of this paper were to identify and discuss: (1) current concerns with nutrition label communication strategies; (2) opportunities to improve the communication of nutrition information via food labels, with a specific focus on serving size information; and (3) important future areas of research on nutrition labeling as a tool to improve diet. We suggest that research on nutrition labeling should focus on ways to improve food labels' ability to capture consumer attention, reduce label complexity and convey numeric nutrition information in simpler and more meaningful ways, such as through interpretive food labels, the addition of simple text, reduced use of percentages and easy-to-understand presentation of serving size information.

  14. Stigma of a label: educational expectations for high school students labeled with learning disabilities.

    Science.gov (United States)

    Shifrer, Dara

    2013-01-01

    Poorer outcomes for youth labeled with learning disabilities (LDs) are often attributed to the student's own deficiencies or cumulative disadvantage; but the more troubling possibility is that special education placement limits rather than expands these students' opportunities. Labeling theory partially attributes the poorer outcomes of labeled persons to stigma related to labels. This study uses data on approximately 11,740 adolescents and their schools from the Education Longitudinal Survey of 2002 to determine if stigma influences teachers' and parents' educational expectations for students labeled with LDs and labeled adolescents' expectations for themselves. Supporting the predictions of labeling theory, teachers and parents are more likely to perceive disabilities in, and hold lower educational expectations for labeled adolescents than for similarly achieving and behaving adolescents not labeled with disabilities. The negative effect of being labeled with LDs on adolescents' educational expectations is partially mechanized through parents' and particularly teachers' lower expectations.

  16. An Optimal Labeling Scheme for Ancestry Queries

    CERN Document Server

    Fraigniaud, Pierre

    2009-01-01

    An ancestry labeling scheme assigns labels (bit strings) to the nodes of rooted trees such that ancestry queries between any two nodes in a tree can be answered merely by looking at their corresponding labels. The quality of an ancestry labeling scheme is measured by its label size, that is the maximal number of bits in a label of a tree node. In addition to its theoretical appeal, the design of efficient ancestry labeling schemes is motivated by applications in web search engines. For this purpose, even small improvements in the label size are important. In fact, the literature about this topic is interested in the exact label size rather than just its order of magnitude. As a result, following the proposal of a simple interval-based ancestry scheme with label size $2\\log_2 n$ bits (Kannan et al., STOC '88), a considerable amount of work was devoted to improve the bound on the size of a label. The current state of the art upper bound is $\\log_2 n + O(\\sqrt{\\log n})$ bits (Abiteboul et al., SODA '02) which is...

    This study examined the effects of the verbal labels procedure and vocabulary skills on low-socioeconomic status (SES) preschool children's eyewitness memory. Children (N = 176) aged 3-5 years witnessed a conflict event and were then questioned about it in either a standard or a verbal labels interview. Findings revealed that children with higher rather than lower vocabulary skills produced more complete and accurate memories. Children who were given the verbal labels interview recalled more information, which included both correct and incorrect details. Overall, the verbal labels procedure did not improve children's performance on direct questions, but children with low vocabulary skills answered direct questions more accurately if they were given the verbal labels interview than when they were not. Implications of the findings for memory performance of low-SES children are discussed.

    Chemical signals yield critical socio-ecological information in many animals, such as species, identity, social status or sex, but have been poorly investigated in birds. Recent results showed that chemical signals are used to recognize their nest and partner by some petrel seabirds whose olfactory anatomy is well developed and which possess a life-history propitious to olfactory-mediated behaviours. Here, we investigate whether blue petrels (Halobaena caerulea) produce some chemical labels potentially involved in kin recognition and inbreeding avoidance. To overcome methodological constraints of chemical analysis and field behavioural experiments, we used an indirect behavioural approach, based on mice olfactory abilities in discriminating odours. We showed that mice (i) can detect odour differences between individual petrels, (ii) perceive a high odour similarity between a chick and its parents, and (iii) perceive this similarity only before fledging but not during the nestling developmental stage. Our results confirm the existence of an individual olfactory signature in blue petrels and show for the first time, to our knowledge, that birds may exhibit an olfactory kin label, which may have strong implications for inbreeding avoidance.

    The goal of this review is to summarize and critically assess information concerning the biotin method to label red blood cells (RBC) for use in studies of RBC and transfusion biology-information that will prove useful to a broad audience of clinicians and scientists. A review of RBC biology, with emphasis on RBC senescence and in vivo survival, is included, followed by an analysis of the advantages and disadvantages of biotin-labeled RBC (BioRBC) for measuring circulating RBC volume, posttransfusion RBC recovery, RBC life span, and RBC age-dependent properties. The advantages of BioRBC over (51)Cr RBC labeling, the current reference method, are discussed. Because the biotin method is straightforward and robust, including the ability to follow the entire life spans of multiple RBC populations concurrently in the same subject, BioRBC offers distinct advantages for studying RBC biology and physiology, particularly RBC survival. The method for biotin labeling, validation of the method, and application of BioRBCs to studies of sickle cell disease, diabetes, and anemia of prematurity are reviewed. Studies documenting the safe use of BioRBC are reviewed; unanswered questions requiring future studies, remaining concerns, and regulatory barriers to broader application of BioRBC including adoption as a new reference method are also presented.

  7. The System of Register Labels in plWordNet

    Full Text Available The System of Register Labels in plWordNet Stylistic registers influence word usage. Both traditional dictionaries and wordnets assign lexical units to registers, and there is a wide range of solutions. A system of register labels can be flat or hierarchical, with few labels or many, homogeneous or decomposed into sets of elementary features. We review the register label systems in lexicography, and then discuss our model, designed for plWordNet, a large wordnet for Polish. There follows a detailed comparative analysis of several register systems in Polish lexical resources. We also present the practical effect of the adoption of our flat, small and homogeneous system: a relatively high consistency of register assignment in plWordNet, as measured by inter-annotator agreement on a manageable sample. Large-scale conclusions for the whole plWordNet remain to be made once the annotation has been completed, but the experience half-way through this labour-intensive exercise is very encouraging.

    2015-06-16

    Groups of individuals can sometimes make more accurate judgments than the average individual could make alone. We tested whether this group advantage extends to lie detection, an exceptionally challenging judgment with accuracy rates rarely exceeding chance. In four experiments, we find that groups are consistently more accurate than individuals in distinguishing truths from lies, an effect that comes primarily from an increased ability to correctly identify when a person is lying. These experiments demonstrate that the group advantage in lie detection comes through the process of group discussion, and is not a product of aggregating individual opinions (a "wisdom-of-crowds" effect) or of altering response biases (such as reducing the "truth bias"). Interventions to improve lie detection typically focus on improving individual judgment, a costly and generally ineffective endeavor. Our findings suggest a cheap and simple synergistic approach of enabling group discussion before rendering a judgment.

  12. Link Label Prediction in Signed Citation Network

    KAUST Repository

    Akujuobi, Uchenna

    2016-04-12

    Link label prediction is the problem of predicting the missing labels or signs of all the unlabeled edges in a network. For signed networks, these labels can either be positive or negative. In recent years, different algorithms have been proposed such as using regression, trust propagation and matrix factorization. These approaches have tried to solve the problem of link label prediction by using ideas from social theories, where most of them predict a single missing label given that labels of other edges are known. However, in most real-world social graphs, the number of labeled edges is usually less than that of unlabeled edges. Therefore, predicting a single edge label at a time would require multiple runs and is more computationally demanding. In this thesis, we look at link label prediction problem on a signed citation network with missing edge labels. Our citation network consists of papers from three major machine learning and data mining conferences together with their references, and edges showing the relationship between them. An edge in our network is labeled either positive (dataset relevant) if the reference is based on the dataset used in the paper or negative otherwise. We present three approaches to predict the missing labels. The first approach converts the label prediction problem into a standard classification problem. We then, generate a set of features for each edge and then adopt Support Vector Machines in solving the classification problem. For the second approach, we formalize the graph such that the edges are represented as nodes with links showing similarities between them. We then adopt a label propagation method to propagate the labels on known nodes to those with unknown labels. In the third approach, we adopt a PageRank approach where we rank the nodes according to the number of incoming positive and negative edges, after which we set a threshold. Based on the ranks, we can infer an edge would be positive if it goes a node above the

    Utilization of isotopically labeled proteins and peptides is a routinely employed approach in biomolecular NMR investigations. The widespread availability of inexpensive, uniformly (13) C-enriched glucose now makes it possible to produce uniformly (13) C-labeled natural products by microbial fermentation. In this feature article, the authors describe an experimental approach for the rapid structural characterization of uniformly (13) C-labeled natural products based on the Constant-Time HSQC (CT-HSQC) experiment. Rigorous theoretical evaluation of the CT-HSQC experiment allowed the applicability of the experiment to be expanded from the traditional, narrow scope of labeled amino acids to encompass virtually any small molecule or U-(13) C labeled natural product. A suite of experiments including CT-HSQC, (13) C-(13) C COSY, and COSYLR experiments is sufficient for the structure elucidation of uniformly (13) C-labeled small molecules and natural products. Differences in NMR approaches for structure elucidation of natural abundance and uniformly (13) C-labeled molecules are also discussed. The present work provides a researcher working in this area of natural products chemistry with NMR structure elucidation tools for investigating (13) C-labeled small molecules and natural products.

  14. Does green mean healthy? Nutrition label color affects perceptions of healthfulness.

    2013-01-01

    The food industry has recently implemented numerous front-of-package nutrition labels to readily convey key aspects a food product's nutritional profile to consumers (e.g., calories and fat content). Although seemingly well-intentioned, such labels might lead consumers to perceive relatively poor nutrition foods in a healthier light. The present research explores whether one underresearched aspect of nutrition labels-namely, their color-might influence perceptions of a product's healthfulness. In Study 1, participants perceived a candy bar as healthier when it bore a green rather than a red calorie label, despite the fact that the labels conveyed the same calorie content. Study 2 examined the perceived healthfulness of a candy bar bearing a green versus white calorie label and assessed individual differences in the importance of healthy eating. Overall, results suggest that green labels increase perceived healthfulness, especially among consumers who place high importance on healthy eating. Discussion focuses on implications for health-related judgment and nutrition labeling.

    Human platelets were labelled in the absence of presence of plasma using {sup 111}In-labelled oxine sulphate, tropolone or 2-mercaptopyridine-N-oxide (MPO). Under in vitro and in vivo conditions, platelet functions were evaluated by measuring their aggregability, survival, recovery and early distribution. High labelling efficiency was achieved in saline labelling, whereas with plasma labelling, it was necessary to concentrate the platelet-rich plasma to 4.8x10{sup 6} platelets/{mu}l. The aggregation of platelets labelled in plasma or saline was compared with that of controls; platelets labelled in saline showed lower aggregability in 2 {mu}M ADP but not in 5 {mu}M ADP nor with collagen. No significant differences in platelet survival and recovery were noted between platelets labelled in plasma and those labelled in saline. Our results indicate that partial loss of ADP aggregability in vitro does not influence the in vivo viability of platelets labelled in saline. Scintigraphic studies showed that platelets labelled in a saline medium were temporarily sequestrated in the liver but not in the spleen or heart. Thus, platelet labelling in saline does not affect platelet function adversely, but platelets labelled in plasma are more desirable for assessing the early distribution of platelets in the reticuloendothelial system.

  19. ML-MG: Multi-label Learning with Missing Labels Using a Mixed Graph

    KAUST Repository

    Wu, Baoyuan

    2015-12-07

    This work focuses on the problem of multi-label learning with missing labels (MLML), which aims to label each test instance with multiple class labels given training instances that have an incomplete/partial set of these labels (i.e. some of their labels are missing). To handle missing labels, we propose a unified model of label dependencies by constructing a mixed graph, which jointly incorporates (i) instance-level similarity and class co-occurrence as undirected edges and (ii) semantic label hierarchy as directed edges. Unlike most MLML methods, We formulate this learning problem transductively as a convex quadratic matrix optimization problem that encourages training label consistency and encodes both types of label dependencies (i.e. undirected and directed edges) using quadratic terms and hard linear constraints. The alternating direction method of multipliers (ADMM) can be used to exactly and efficiently solve this problem. To evaluate our proposed method, we consider two popular applications (image and video annotation), where the label hierarchy can be derived from Wordnet. Experimental results show that our method achieves a significant improvement over state-of-the-art methods in performance and robustness to missing labels.

  20. Optimal design of isotope labeling experiments.

    Stable isotope labeling experiments (ILE) constitute a powerful methodology for estimating metabolic fluxes. An optimal label design for such an experiment is necessary to maximize the precision with which fluxes can be determined. But often, precision gained in the determination of one flux comes at the expense of the precision of other fluxes, and an appropriate label design therefore foremost depends on the question the investigator wants to address. One could liken ILE to shadows that metabolism casts on products. Optimal label design is the placement of the lamp; creating clear shadows for some parts of metabolism and obscuring others.An optimal isotope label design is influenced by: (1) the network structure; (2) the true flux values; (3) the available label measurements; and, (4) commercially available substrates. The first two aspects are dictated by nature and constrain any optimal design. The second two aspects are suitable design parameters. To create an optimal label design, an explicit optimization criterion needs to be formulated. This usually is a property of the flux covariance matrix, which can be augmented by weighting label substrate cost. An optimal design is found by using such a criterion as an objective function for an optimizer. This chapter uses a simple elementary metabolite units (EMU) representation of the TCA cycle to illustrate the process of experimental design of isotope labeled substrates.

    Everyday we choose between a variety of different food items trying to reach a decision that fits best our needs. These decisions are highly dependent on the context in which the alternatives are presented (e.g. labeling). We investigate the influence of cognition on food evaluation, using an fMRI experiment in which subjects saw and bid on different foods labeled with (or without) a widely known German emblem for organically produced food. Increased activity in the ventral striatum was found for foods labeled "organic" in comparison to conventionally labeled food. Between-subject differences in activity were related to actual everyday consumption behavior of organic food.

  4. Simultaneous Segmentation and Statistical Label Fusion.

    Labeling or segmentation of structures of interest in medical imaging plays an essential role in both clinical and scientific understanding. Two of the common techniques to obtain these labels are through either fully automated segmentation or through multi-atlas based segmentation and label fusion. Fully automated techniques often result in highly accurate segmentations but lack the robustness to be viable in many cases. On the other hand, label fusion techniques are often extremely robust, but lack the accuracy of automated algorithms for specific classes of problems. Herein, we propose to perform simultaneous automated segmentation and statistical label fusion through the reformulation of a generative model to include a linkage structure that explicitly estimates the complex global relationships between labels and intensities. These relationships are inferred from the atlas labels and intensities and applied to the target using a non-parametric approach. The novelty of this approach lies in the combination of previously exclusive techniques and attempts to combine the accuracy benefits of automated segmentation with the robustness of a multi-atlas based approach. The accuracy benefits of this simultaneous approach are assessed using a multi-label multi- atlas whole-brain segmentation experiment and the segmentation of the highly variable thyroid on computed tomography images. The results demonstrate that this technique has major benefits for certain types of problems and has the potential to provide a paradigm shift in which the lines between statistical label fusion and automated segmentation are dramatically blurred.

    The Arctic vortex is a persistent large-scale cyclonic circulation in the middle and upper troposphere and the stratosphere. Its activity and variation control the semi-permanent active centers of Pan-Arctic and the short-time cyclone activity in the subarctic areas. Its strength variation, which directly relates to the atmosphere, ocean, sea ice and ecosystem of the Arctic, can affect the lower atmospheric circulation, the weather of subarctic area and even the weather of middle latitude areas. The 2003 Chinese Second Arctic Research Expedition experienced the transition of the stratosphereic circulation from a warm anticyclone to a cold cyclone during the ending period of Arctic summertime, a typical establishing process of the polar vortex circulation. The impact of the polar vortex variation on the low-level circulation has been investigated by some scientists through studying the coupling mechanisms of the stratosphere and troposphere. The impact of the Stratospheric Sudden Warming (SFW) events on the polar vortex variation was drawing people's great attention in the fifties of the last century. The Arctic Oscillation (AO) , relating to the variation of the Arctic vortex, has been used to study the impact of the Arctic vortex on climate change. The recent Arctic vortex studies are simply reviewed and some discussions on the Arctic vertex are given in the paper. Some different views and questions are also discussed.

    2016-01-01

    Full Text Available Background: There are diverging opinions about scientific evidence for Homoeopathy, but evidence for conventional medicine is not perfect either. In fact, proof for Homoeopathy is not inferior to conventional. However, the evidence for Homoeopathy has been downplayed by selection of trials (cherry-picking. The effect of Homoeopathy in randomized controlled trials (RCTs, however, is small due to many ineffective prescriptions. This is caused by shortcomings of our Materia Medica and Repertories. Discussion: The hegemony of the RCT is increasingly questioned; it does not provide all answers, especially not for the individual patient. The individual patient wants to know his individual prognosis: Will this medicine work for him? This is even more important than his individual diagnosis. It is possible to assess prognosis scientifically the same way as diagnosis. Prognostic research is based on daily practice; practitioners should have knowledge about statistics to fulfill their role in this process. Conclusion: The discussion in this paper elucidates that RCT has its limitations, especially for the patient whose main concern is recovery/prognosis. Drug validation is a key to improve the outcome of clinical practice in Homoeopathy.

    Disclaimer labels on airbrushed media images have generated political attention and advocacy as a social policy approach to promoting positive body image. Experimental research suggests that labelling is ineffective and consumers' viewpoints have been overlooked. A mixed-method study explored British consumers' (N = 1555, aged 11-78 years) opinions on body image and social policy approaches. Thematic analysis indicated scepticism about the effectiveness of labelling images. Quantitatively, adults, although not adolescents, reported that labelling was unlikely to improve body image. Appearance diversity in media and reorienting social norms from appearance to function and health were perceived as effective strategies. Social policy and research implications are discussed.

    The effects of five UICC asbestos samples, titanium dioxide, and quartz on the bovine red cell membrane have been studied in erythrocyte ghosts by the spin labelling technique. Analysis of the electron paramagnetic resonance (EPR) spectra of two sulphydryl reactive spin labels and one fatty acid spin label in red cell ghosts showed modifications in membrane protein after asbestos treatment but no alterations in membrane lipids. In experiments with quartz no membrane changes were noted but titanium dioxide altered the proteins bound with the protein reactive spin label used in the present study. The possible mechanism for these effects is discussed.

    S-(-)-N-[(1-ethyl-2-pyrrolidinyl)methyl]-5-iodo-2,3-dimethoxybenzamide (proposed generic name, epidepride) is a very potent dopamine D2 antagonist. It was synthesized by five steps from 3-methoxysalicylic acid. [131I]epidepride was obtained in 97.3% radiochemical yields from the corresponding 5-(tributyltin) derivative using hydrogen peroxide as the oxidant. The aryltin precursor was prepared from non-labelled epidepride by palladium-catalyzed stannylation using bis(tri-n-butyltin) in triethylamine. [131I]epidepride was stable under 4℃, and partition coefficient was 72.3 at pH 7.40. The biodistribution study in rats exihibited high localization in the striatum of the brain with the striatum/cerebellum ratio reaching 237/1 at 320 min postinjection.All these results suggest that[131I]epidepride may be usedd widely as a useful dopamineD2 receptor imaging agent for SPECT.

Legal regulations precisely give instructions on the range and the way of the presentation of these data, so they could be clear and understandable for the average consumer. Since 25th of November 2005, the information about allergens’ presence must be placed on the label, regardless of their content in the product (Directive 2003/89/WE... 2003 – Off. J. L 308: 15-18. The Regulation (WE No 1924/2006 about placing the nutritional information and medicinal claims concerning foods (Regulation (WE No 1924/2006... 2006 a is valid in all countries of European Union since 1st of July 2007 (Off.

    2013-09-01

    Metabolic fluxes and the capacity to modulate them are a crucial component of the ability of the plant cell to react to environmental perturbations. Our ability to quantify them and to attain information concerning the regulatory mechanisms that control them is therefore essential to understand and influence metabolic networks. For all but the simplest of flux measurements labelling methods have proven to be the most informative. Both steady-state and dynamic labelling approaches have been adopted in the study of plant metabolism. Here the conceptual basis of these complementary approaches, as well as their historical application in microbial, mammalian and plant sciences, is reviewed, and an update on technical developments in label distribution analyses is provided. This is supported by illustrative cases studies involving the kinetic modelling of secondary metabolism. One issue that is particularly complex in the analysis of plant fluxes is the extensive compartmentation of the plant cell. This problem is discussed from both theoretical and experimental perspectives, and the current approaches used to address it are assessed. Finally, current limitations and future perspectives of kinetic modelling of plant metabolism are discussed.

    Full Text Available Heather P Whitley1,2, Kristi Kelley11Department of Pharmacy Practice, Auburn University Harrison School of Pharmacy, Auburn, AL, USA; 2Department of Community and Rural Medicine, University of Alabama School of Medicine, Tuscaloosa, AL, USAPurpose: To describe a case of hypoglycemia induced by off-label use of sitagliptin in an adult patient with type 2 diabetes.Case summary: Addition of sitagliptin to metformin, glimepiride, and NovoLog® 70/30 Mix induced hypoglycemia in a 55-year-old Caucasian female. Hypoglycemia improved, although still occurred periodically, following sulfonylurea discontinuation and a 28% insulin dose reduction. Hypoglycemic symptoms were absent during a 3-day dechallange but occurred again upon sitagliptin reinitiation.Discussion: Although the mechanism of action of sitagliptin does not predispose patients to hypoglycemic events, when combined with hypoglycemia-inducing medications, eg, sulfonylureas or insulin, and possibly meglitinides, the incidence likely increases.Conclusions: Caution should be used when combining sitagliptin with either sulfonylureas or insulin, and possibly meglitinides, for the treatment of type 2 diabetes as hypoglycemia may ensue. Hypoglycemia due to off-label combinations with insulin and sitagliptin may be prevented by reducing meal-time insulin doses. Prescribers and patients should vigilantly monitor for hypoglycemic events when using sitagliptin off-label with similar pharmacologic combinations such as meglitinides and other rapid-acting insulin products. Additionally, clinicians may encounter resistance from insurance companies to cover such off-label combinations.Keywords: diabetes, DPP-IV inhibitor, sitagliptin, hypoglycemia, drug-induced, off-label

  19. Chain store management through private labels strategy

    Directory of Open Access Journals (Sweden)

    Martina Sopta

    2007-07-01

    Full Text Available The purpose of this paper is to examine the market shares of private labels in the European Union and on the global market, and to compare the results of the analysis with the level of presence of private labels on the Croatian market. Moreover, through the application of macro and microeconomic tools, the author tried to estimate the future trends of private labels in Croatia.For the purpose of the paper secondary and primary data was used in the research. Relevant scientific and professional literature of local and foreign authors was analyzed. In addition, a few recent research studies were analyzed and their results compared. Field research has been conducted by the survey method, with 225 respondents included in the intentional sample.The main hypothesis of the paper based on research is that, in total sales, private labels are gaining a growing share in all markets, regardless of the development level of those markets. Alongside the main hypothesis of the work, three supporting hypotheses were tested to see which private labels are a good alternative to other brands on the world market. Private labels are generally developed on generic products. The third supporting hypothesis starts from the assumption that the investments in the promotion of private labels are negligible, resulting in lower prices of thoseproducts. The results of research and analyses in the work indicate that the position of private labels will strengthen internationally, as part of the process of liberalization and globalization of trade flows. In the process of purchase of private labels the positioning of the point of sale and price have an increasing contribution. With the concentration of commerce in chain stores, the share of private labels grows, approaching a half of the total sales in some countries. Considering the Croatian market, according to the international product life cycle theory, the share of private labels in the total sales will grow in the future

  20. Using Ensemble Decisions and Active Selection to Improve Low-Cost Labeling for Multi-View Data

    Science.gov (United States)

    Rebbapragada, Umaa; Wagstaff, Kiri L.

    2011-01-01

    This paper seeks to improve low-cost labeling in terms of training set reliability (the fraction of correctly labeled training items) and test set performance for multi-view learning methods. Co-training is a popular multiview learning method that combines high-confidence example selection with low-cost (self) labeling. However, co-training with certain base learning algorithms significantly reduces training set reliability, causing an associated drop in prediction accuracy. We propose the use of ensemble labeling to improve reliability in such cases. We also discuss and show promising results on combining low-cost ensemble labeling with active (low-confidence) example selection. We unify these example selection and labeling strategies under collaborative learning, a family of techniques for multi-view learning that we are developing for distributed, sensor-network environments.

    The chief physical properties of the radionuclide In111 are outlined, and compared with those of three other radionuclides, Tc99m, I131 and Cr51 which have similar applications. It is pointed out that the gamma-rays of In111 are appreciably more penetrating in lead than those of Tc99m and the significance of this, both in the use of shielding on syringes and in the effectiveness of lead glass screens is discussed. Examples are given of the dosimetry for In111 labelled cells in humans and it is noted that the absorbed dose in the spleen per mCi (37 MBq) injected may be some 10 rad (0.1 Gy). The problems that have been noted of damage to cells arising from oxine labelling and now considered to be due to radiation damage are briefly reviewed.

  8. Multi-label Dictionary Learning for Image Annotation.

    Jing, Xiao-Yuan; Wu, Fei; Li, Zhiqiang; Hu, Ruimin; Zhang, David

    2016-03-31

    Image annotation has attracted lots of research interest, and multi-label learning is an effective technique for image annotation. How to effectively exploit the underlying correlation among labels is a crucial task for multi-label learning. Most existing multi-label learning methods exploit the label correlation only in the output label space, leaving the connection between label and features of images untouched. Although recently some methods attempt towards exploiting the label correlation in the input feature space by using the label information, they cannot effectively conduct the learning process in both spaces simultaneously, and there still exists much room for improvement. In this paper, we propose a novel multi-label learning approach, named Multi-Label Dictionary Learning with label consistency regularization and partial-identical label embedding (MLDL), which conducts multi-label dictionary learning and partial-identical label embedding simultaneously. In the input feature space, we incorporate the dictionary learning technique into multi-label learning and design the label consistency regularization term to learn better representation of features. In the output label space, we design the partial-identical label embedding, in which samples with the exactly same label set can cluster together, and samples with partial-identical label sets can collaboratively represent each other. Experimental results on three widely used image datasets including Corel 5K, IAPR TC12 and ESP Game demonstrate the effectiveness of the proposed approach.

    Full Text Available Abstract Objective The off-label use, referring to the applicability of pharmaceutical drugs beyond the submitted and from the Federal Institute for Drugs and Medical Devices (BfArM, Bundesamt für Arzneimittel und Medizinprodukte certified and approved administration, is the subject of controversial discussions. the application can be considered in case of severe illness - if no therapeutic alternatives are available - or it exists as a founded perspective for achieving therapeutic success. Methods A latitudinal study for evaluating the application of off-label use supplements was performed at 43 German university and academic teaching hospitals. Five doctors at each hospital applied off-label pharmaceutical drugs and were called upon to share their personal experience to the application of those medications. Results 75 (35% questionnaires were returned out of 22 (51% medical centres with 215 contacted physicians. Off-label use was common for 65 (91% of the physicians. Only 9% of them obviate the application of off-label drugs. About a half of the medication is related to application in obstetrics (54% and in most cases on an every day basis. Uterotonics were the most commonly used off-label medications (34%. The main part of information about off-label use is obtained from personal information of colleagues (66% and personal experience (58%. 34% of physicians think that off label use is risky. Interestingly, the view about off label use of medication varies considerably among physicians from various hospitals. Conclusions The application of off-label pharmaceutical drugs in Germany seems to be a well established practice. More than 90% of participators of our trial use at least one medication outside the administration. This includes particularly prostaglandins, anti-hyper-tonic therapeutics and chemotherapeutics.

    The Illicit nuclear trafficking panel was conducted at the 4th Annual INMM workshop on Reducing the Risk from Radioactive and Nuclear Materials on February 2-3, 2010 in Washington DC. While the workshop occurred prior to the Nuclear Security Summit, April 12-13 2010 in Washington DC, some of the summit issues were raised during the workshop. The Communique of the Washington Nuclear Security Summit stated that 'Nuclear terrorism is one of the most challenging threats to international security, and strong nuclear security measures are the most effective means to prevent terrorists, criminals, or other unauthorized actors from acquiring nuclear materials.' The Illicit Trafficking panel is one means to strengthen nuclear security and cooperation at bilateral, regional and multilateral levels. Such a panel promotes nuclear security culture through technology development, human resources development, education and training. It is a tool which stresses the importance of international cooperation and coordination of assistance to improve efforts to prevent and respond to incidents of illicit nuclear trafficking. Illicit trafficking panel included representatives from US government, an international organization (IAEA), private industry and a non-governmental organization to discuss illicit nuclear trafficking issues. The focus of discussions was on best practices and challenges for addressing illicit nuclear trafficking. Terrorism connection. Workshop discussions pointed out the identification of terrorist connections with several trafficking incidents. Several trafficking cases involved real buyers (as opposed to undercover law enforcement agents) and there have been reports identifying individuals associated with terrorist organizations as prospective plutonium buyers. Some specific groups have been identified that consistently search for materials to buy on the black market, but no criminal groups were identified that specialize in nuclear materials or isotope

    Creatinine is a clinically important index of renal glomerular filtration rate. Urine creatinine levels can be used as a screening test to evaluate kidney function or can be part of the creatinine clearance test. In case of kidney dysfunction or muscle disorders the creatinine concentration in serum/plasma may rise to a higher value than in healthy body. Technetium- 99m has been used in nuclear medicine and in biomedical research to label molecular and cellular structures employed as radiotracers. {sup 99m}Tc is utilized to label molecules and cells, used as radiopharmaceuticals, and also to label biological species. It presents many desirable characteristics. SnCl{sub 2} method is frequently used as a reducing agent in the {sup 99m}Tc- labeling process. Creatinine metabolism might be investigated by using labeled {sup 99m}Tc- creatinine in healthy or uremic rats. (orig.)

    2011-04-01

    Full Text Available In the rush to produce more and more crops to satisfy growing demand producers have had to resort to using a lethal cocktail of pesticides to control disease and insect attack. This has lead to numerous international debates about unhealthy food, the effects of it and the measures that must be taken in order to avoid the harmful effects of genetically modified food consumption demonstrated by specialists. These debates evolve around the benefits of the organic products versus the pure trade trick outlined by some. The organic food movement has earned its well deserved place in many markets around the world. Its prestige is lately being widespread to vast parts of Eastern-Europe as well. Based on data collected from specialized reports and articles on organic products, the aim of this paper is to present the importance of organic products, the regulations on organic food and different labels used around the world in order to certify the organic food products.

    To analyse patterns of knowledge, comprehension, attitudes and practices regarding the traffic light label placed on processed food packages to inform Ecuadorian consumers about levels of added fat, sugar and salt. Twenty-one focus group discussions organized by age group, sex and place of residence. Interviews with representatives of companies that manufacture or market processed foods. Analysis of regulations and structured observations of processed food labels. Cities and towns in Ecuador's coastal, highland and eastern lowland regions. One hundred and seventy-eight participants in twenty-one focus group discussions and nine key informants. Focus group participants knew about the traffic light label and understood the information it conveys, but not all changed their attitudes and practices related to the purchase and consumption of processed foods. Children, adolescents and adult males reported using the information infrequently; adolescents interested in health and adult women used the label the most to select products. Representatives of companies that manufacture or market processed foods generally opposed the policy, stating that the information is misleading. Nevertheless, some companies have reduced levels of added fat, sugar or salt in their products. The traffic light label is an effective tool for conveying complex information. Its potential contribution to reduce consumption of products with high levels of fat, sugar and salt could be enhanced by promoting healthy diets among consumers who have not changed purchasing and consumption behaviour, by placing the label on front panels and by monitoring the production and marketing of processed foods.

    2004-01-01

    Objective: To explore the method of 99Tcm direct labeling of angiostatin (AS) and investigate the stability and bioactivity of the 99Tcm-labeled AS in vitro. Methods: AS was extracted, validated, and then labeled with 99Tcm after having been reduced by 2-ME or SnCl2. The best labeling condition was screened by cross design. The labeling efficiency was measured by TLC and column chromatography. The stability of 99Tcm-AS was observed and compared when BSA, saline and different molar ratios of Cys∶AS were separately added. The bioactivity of 99Tcm-AS was observed in human umbilical vein endothelial cell (CEV304). Results: The labeling efficiency can reach (97±1.5)% for the 2-ME-reducing approach. Its best experimental condition was as follows: AS 100 μg,PB(0.5 mol/L, pH 7.3)1 ml, 2-ME 100 μg, MDP (dissolved in 1 ml saline) 10 μl, and 99TcmO4- 185 MBq. The labeling efficiency using SnCl2-reducing method can reach (90±3.0)%. The best experimental procedure was as follows: AS 100 μg,boric acid buffer(0.1 mol/L, pH 9.0)1 ml, 2%SnCl2 (dissolved in 1 mol/L hydrochloric acid) 20 μl, was added into MDP, which was diluted with 1 ml deoxygenized water, and then 20 μl, 99TcmO4- 185 MBq was added. The product of 99Tcm labeled AS was stable in vitro and had the same bioactivity as AS. Conclusion: 99Tcm direct labeling of AS is simple and efficient. And the bioactivity of 99Tcm-AS has no significant change compared with AS.

    2016-01-01

    This study investigated whether attitudinal variables, such as benevolent and hostile sexism toward men and women, female rape myth acceptance, and tolerance of sexual harassment are related to women labeling their sexual assault experiences as rape. In a sample of 276 female college students, 71 (25.7%) reported at least one experience that met the operational definition of rape, although only 46.5% of those women labeled the experience "rape." Benevolent sexism, tolerance of sexual harassment, and rape myth acceptance, but not hostile sexism, significantly predicted labeling of previous sexual assault experiences by the victims. Specifically, those with more benevolent sexist attitudes toward both men and women, greater rape myth acceptance, and more tolerant attitudes of sexual harassment were less likely to label their past sexual assault experience as rape. The results are discussed for their clinical and theoretical implications.

    In fluorescence labelled immunosensing the discrimination of labels remaining in the bulk solution from labels bound to the analyte at the sensor surface is a basic optical problem. It is shown that application of surface enhanced fluorescence at a layer of noble metal nano-particles can increase the surface-to-background signal ratio. We explain the enhancement mechanism by an electrodynamic model and discuss the interaction between metal particle and fluorophore for the excitation and emission process. We show the principal guidelines for optimization of that processes. We find that the obtained discrimination power increases with decreasing intrinsic quantum efficiency of the fluorophore, suggesting the application of new classes of labels, namely low-quantum efficiency fluorophores. This theoretical finding is shown by a practical model experiment.

    The rapid emergence of metabolomics has enabled system-wide measurements of metabolites in various organisms. However, advances in the mechanistic understanding of metabolic networks remain limited, as most metabolomics studies cannot routinely provide accurate metabolite identification, absolute quantification and flux measurement. Stable isotope labeling offers opportunities to overcome these limitations. Here we describe some current approaches to stable isotope-labeled metabolomics and provide examples of the significant impact that these studies have had on our understanding of cellular metabolism. Furthermore, we discuss recently developed software solutions for the analysis of stable isotope-labeled metabolomics data and propose the bioinformatics solutions that will pave the way for the broader application and optimal interpretation of system-scale labeling studies in metabolomics.

    A label-free sensing approach for the label-free characterization of genetic material with terahertz (THz) electromagnetic waves is presented. Time-resolved THz analysis of polynucleotides demonstrates a strong dependence of the complex refractive index of DNA molecules in the THz frequency range on their hybridization state. By monitoring THz signals one can thus infer the binding state (hybridized or denatured) of oligo- and polynucleotides, enabling the label-free determination the genetic composition of unknown DNA sequences. A broadband experimental proof-of-principle in a free-space analytic configuration, as well as a higher-sensitivity approach using integrated THz sensors reaching femtomol detection levels and demonstrating the capability to detect single-base mutations, are presented. The potential application for next generation high-throughput label-free genetic analytic systems is discussed.

    showing the increase, considering latency and the length of the observation period. Of further interest are results relating to diseases of the urinary tract such as kidney failure in the NPCSs of Basso bacino del fiume Chienti, Taranto, Milazzo and Priolo. Overall, the results discussed above are consistent with the previous findings pertaining to mortality for 1995-2002. The present analysis also introduces a new element - the study of cancer incidence and hospital discharges - which can tell us a great deal about diseases with high survival rates or non lethal ones. The first is the case of thyroid cancer, which presents increases in both databases and for both genders in a number of NPCSs (Brescia-Caffaro, Laghi di Mantova, Milazzo, Sassuolo- Scandiano and Taranto). The study of cancer incidence and hospital discharges also revealed cancer excesses for melanoma, breast cancer and non Hodgkin lymphoma in Brescia-Caffaro NPCS where PCBs (Polychlorinated biphenyl) are the site's main pollutant. PCBs, according to the 2013 evaluation of the International Agency for Research on Cancer, are ascertained human carcinogens for melanoma and probable carcinogens for breast cancer and non-Hodgkin lymphoma. The results pertaining to cancer incidence in the 17 NPCSs can also be presented using rankings by area or disease analyzed by a multivariate hierarchical Bayesian model. These rankings reveal an overlapping of credibility intervals, such that it is not possible to speak of a limited number of cancer sites or of certain NPCSs as being particularly affected. Every NPCS, therefore, must be considered individually and ordering them by ranking of cancer incidence wouldn't be appropriate. Data collected concerning some of the NPCSs in the context of the SENTIERI Project is so conclusive that remediation measures can immediately be put in place. This is the case in the Biancavilla and Brescia-Caffaro NPCSs. A similar conclusion can be drawn for complex locations such as Taranto

    2012-12-01

    Full Text Available We introduce the Mindboggle-101 dataset, the largest and most complete set of free, publicly accessible, manually labeled human brain images. To manually label the macroscopic anatomy in magnetic resonance images of 101 healthy participants, we created a new cortical labeling protocol that relies on robust anatomical landmarks and minimal manual edits after initialization with automated labels. The Desikan-Killiany-Tourville (DKT protocol is intended to improve the ease, consistency, and accuracy of labeling human cortical areas. Given how difficult it is to label brains, the Mindboggle-101 dataset is intended to serve as brain atlases for use in labeling other brains, as a normative dataset to establish morphometric variation in a healthy population for comparison against clinical populations, and contribute to the development, training, testing, and evaluation of automated registration and labeling algorithms. To this end, we also introduce benchmarks for the evaluation of such algorithms by comparing our manual labels with labels automatically generated by probabilistic and multi-atlas registration-based approaches. All data and related software and updated information are available on the http://www.mindboggle.info/data/ website.

    Directory of Open Access Journals (Sweden)

    W Michael ePanneton

    2014-01-01

    Full Text Available A dramatic bradycardia is induced by underwater submersion in vertebrates. The location of parasympathetic preganglionic cardiac motor neurons driving this aspect of the diving response was investigated using cFos immunohistochemistry combined with retrograde transport of cholera toxin subunit B (CTB to double-label neurons. After pericardial injections of CTB, trained rats voluntarily dove underwater, and their heart rates dropped immediately to 95±2bpm, an 80% reduction. After immunohistochemical processing, the vast majority of CTB labeled neurons were located in the reticular formation from the rostral cervical spinal cord to the facial motor nucleus, confirming previous studies. Labeled neurons caudal to the rostral ventrolateral medulla were usually spindle-shaped aligned along an oblique line running from the dorsal vagal nucleus to the ventrolateral reticular formation, while those more rostrally were multipolar with extended dendrites. Nine percent of retrogradely-labeled neurons were positive for both cFos and CTB after diving and 74% of these were found rostral to the obex. CTB also was transported transganglionically in primary afferent fibers, resulting in large granular deposits in dorsolateral, ventrolateral, and commissural subnuclei of the nucleus tractus solitarii and finer deposits in lamina I and IV-V of the trigeminocervical complex. The overlap of parasympathetic preganglionic cardiac motor neurons activated by diving with those activated by baro- and chemoreceptors in the rostral ventrolateral medulla is discussed. Thus the profound bradycardia seen with underwater submersion reinforces the notion that the mammalian diving response is the most powerful autonomic reflex known.

    2015-01-01

    Generative algorithms for random graphs have yielded insights into the structure and evolution of real-world networks. Most networks exhibit a well-known set of properties, such as heavy-tailed degree distributions, clustering and community formation. Usually, random graph models consider only structural information, but many real-world networks also have labelled vertices and weighted edges. In this paper, we present a generative model for random graphs with discrete vertex labels and numeric edge weights. The weights are represented as a set of Beta Mixture Models (BMMs) with an arbitrary number of mixtures, which are learned from real-world networks. We propose a Bayesian Variational Inference (VI) approach, which yields an accurate estimation while keeping computation times tractable. We compare our approach to state-of-the-art random labelled graph generators and an earlier approach based on Gaussian Mixture Models (GMMs). Our results allow us to draw conclusions about the contribution of vertex labels a...

    2005-10-23

    The paper describes a novel technique to visualize graphs with extended node and link labels. The lengths of these labels range from a short phrase to a full sentence to an entire paragraph and beyond. Our solution is different from all the existing approaches that almost always rely on intensive computational effort to optimize the label placement problem. Instead, we share the visualization resources with the graph and present the label information in static, interactive, and dynamic modes without the requirement for tackling the intractability issues. This allows us to reallocate the computational resources for dynamic presentation of real-time information. The paper includes a user study to evaluate the effectiveness and efficiency of the visualization technique.

    Let G =(V,E) be a finite,simple and undirected graph with p vertices and q edges.An (a,d)-vertex-antimagic total labeling of G is a bijection f from V(G).∪E(G) onto the set of consecutive integers 1,2,...,p + q,such that the vertex-weights form an arithmetic progression with the initial term a and difference d,where the vertex-weight of x is the sum of the value f(x) assigned to the vertex x together with all values f(xy) assigned to edges xy incident to x.Such labeling is called super if the smallest possible labels appear on the vertices.In this paper,we study the properties of such labelings and examine their existence for 2r-regular graphs when the difference d is 0,1,...,r + 1.

    Full Text Available Abstract Background Mesenchymal stem cells (MSCs are multipotent cells with the potential to differentiate into bone, cartilage, fat and muscle cells and are being investigated for their utility in cell-based transplantation therapy. Yet, adequate methods to track transplanted MSCs in vivo are limited, precluding functional studies. Quantum Dots (QDs offer an alternative to organic dyes and fluorescent proteins to label and track cells in vitro and in vivo. These nanoparticles are resistant to chemical and metabolic degradation, demonstrating long term photostability. Here, we investigate the cytotoxic effects of in vitro QD labeling on MSC proliferation and differentiation and use as a cell label in a cardiomyocyte co-culture. Results A dose-response to QDs in rat bone marrow MSCs was assessed in Control (no-QDs, Low concentration (LC, 5 nmol/L and High concentration (HC, 20 nmol/L groups. QD yield and retention, MSC survival, proinflammatory cytokines, proliferation and DNA damage were evaluated in MSCs, 24 -120 hrs post QD labeling. In addition, functional integration of QD labeled MSCs in an in vitro cardiomyocyte co-culture was assessed.

    Combining the decomposition of Casimir operators induced by the embedding of a subalgebra into a semisimple Lie algebra with the properties of commutators of subgroup scalars, an analytical algorithm for the computation of missing label operators with the commutativity requirement is proposed. Two new criteria for subgroups scalars to commute are given. The algorithm is completed with a recursive method to construct orthonormal bases of states. As examples to illustrate the procedure, four labelling problems are explicitly studied.

  11. Pharmacogenetic information for patients on drug labels.

    2014-01-01

    Advances in pharmacogenetic research have improved our understanding of adverse drug responses and have led to the development of pharmacogenetic tests and targeted drugs. However, the extent of the communication process and provision of information to patients about pharmacogenetics is unclear. Pharmacogenetic information may be included in sections of a drug's package insert intended for patients, which is provided directly to patients or communicated via the health provider. To determine what pharmacogenetic information, if any, is included in patient-targeted sections of the drug label, we reviewed the labels listed in the US Food and Drug Administration's Table of Pharmacogenomic Biomarkers in Drug Labels. To date, 140 drugs include pharmacogenetic-related information in the approved label. Our analysis revealed that pharmacogenetic information is included in patient-targeted sections for a minority (n=29; 21%) of drug labels, with no obvious pattern associated with the inclusion of pharmacogenetic information. Therefore, patients are unlikely to learn about pharmacogenetics through written materials dispensed with the drug. Given that there are also inconsistencies with regard to inclusion of pharmacogenetic information in the patient counseling information section, it is also unlikely that patients are receiving adequate pharmacogenetic information from their provider. The inconsistent presence of pharmacogenetic information in patient-targeted sections of drug labels suggests a need to review the criteria for inclusion of information in patient-targeted sections in order to increase consistency and patient knowledge of pharmacogenetic information.

    The misuse of medicine is a serious public health issue worldwide. An important factor that contributes to the misuse of medicine is the lack of medication label viewing by consumers. The objective of the present study is to examine the socio-economic, demographic and lifestyle factors associated with medication label viewing among Malaysian adults. The empirical analysis is based on a nationally representative data set of 30,992 respondents. An ordered probit model is used to examine different types of medication label viewers. The results of this study suggest that socio-economic (i.e. age, income level, education level, location of residence), demographic (i.e. gender, ethnicity, marital status) and lifestyle factors (i.e. physical activity, smoking) have significant effects on medication label viewing. It is found that age, low-income and low-education level reduce the likelihood of viewing medication label. Based on these findings, several policy implications are suggested. The present study provides policy makers with baseline information regarding which cohorts of individuals to focus on in efforts to increase the frequency of medication label viewing.

  13. Gold Nanoparticle Labels Amplify Ellipsometric Signals

    2008-01-01

    The ellipsometric method reported in the immediately preceding article was developed in conjunction with a method of using gold nanoparticles as labels on biomolecules that one seeks to detect. The purpose of the labeling is to exploit the optical properties of the gold nanoparticles in order to amplify the measurable ellipsometric effects and thereby to enable ultrasensitive detection of the labeled biomolecules without need to develop more-complex ellipsometric instrumentation. The colorimetric, polarization, light-scattering, and other optical properties of nanoparticles depend on their sizes and shapes. In the present method, these size-and-shape-dependent properties are used to magnify the polarization of scattered light and the diattenuation and retardance of signals derived from ellipsometry. The size-and-shape-dependent optical properties of the nanoparticles make it possible to interrogate the nanoparticles by use of light of various wavelengths, as appropriate, to optimally detect particles of a specific type at high sensitivity. Hence, by incorporating gold nanoparticles bound to biomolecules as primary or secondary labels, the performance of ellipsometry as a means of detecting the biomolecules can be improved. The use of gold nanoparticles as labels in ellipsometry has been found to afford sensitivity that equals or exceeds the sensitivity achieved by use of fluorescence-based methods. Potential applications for ellipsometric detection of gold nanoparticle-labeled biomolecules include monitoring molecules of interest in biological samples, in-vitro diagnostics, process monitoring, general environmental monitoring, and detection of biohazards.

    We elaborate basic chemical principles and current laboratory procedures for sequencing end-labeled DNA by partial cleavage and gel electrophoresis (A. M. Maxam and W. Gilbert, Proc. Natl. Acad. Sci. USA, 1977, v. 74, p. 560-564). We provide step-by-step protocols for 32P-labeling DNA ends, segregating the labeled ends by cutting with a second restriction enzyme or separating strands, partially cleaving the DNA at specific bases with reagents, electrophoresing the labeled products of cleavage on sequencing gels, and interpreting sequencing band patterns. Many of these procedures have been condensed, to make them faster and easier, and some are new. We also discuss sequencing strategies, and suggest a technique which will reduce plasmid or viral DNA to a collection of singly-end-labeled fragments in one day, for efficient sequencing of these chromosomes in 250-nucleotide blocks.

    2012-04-01

    One of the aims of the Science and Technology Committee (STC) of the Group on Earth Observations (GEO) was to establish a GEO Label- a label to certify geospatial datasets and their quality. As proposed, the GEO Label will be used as a value indicator for geospatial data and datasets accessible through the Global Earth Observation System of Systems (GEOSS). It is suggested that the development of such a label will significantly improve user recognition of the quality of geospatial datasets and that its use will help promote trust in datasets that carry the established GEO Label. Furthermore, the GEO Label is seen as an incentive to data providers. At the moment GEOSS contains a large amount of data and is constantly growing. Taking this into account, a GEO Label could assist in searching by providing users with visual cues of dataset quality and possibly relevance; a GEO Label could effectively stand as a decision support mechanism for dataset selection. Currently our project - GeoViQua, - together with EGIDA and ID-03 is undertaking research to define and evaluate the concept of a GEO Label. The development and evaluation process will be carried out in three phases. In phase I we have conducted an online survey (GEO Label Questionnaire) to identify the initial user and producer views on a GEO Label or its potential role. In phase II we will conduct a further study presenting some GEO Label examples that will be based on Phase I. We will elicit feedback on these examples under controlled conditions. In phase III we will create physical prototypes which will be used in a human subject study. The most successful prototypes will then be put forward as potential GEO Label options. At the moment we are in phase I, where we developed an online questionnaire to collect the initial GEO Label requirements and to identify the role that a GEO Label should serve from the user and producer standpoint. The GEO Label Questionnaire consists of generic questions to identify whether

    2008-01-01

    Objective In light of the emerging obesity pandemic, front-of-pack calories labels may be an important tool to assist consumers in making informed healthier food choices. However, there is little prior research to guide key decisions on whether caloric content should be expressed in absolute terms or relative to recommended daily intake, whether it should be expressed in per serving or per 100 g and whether the information should be further brought alive for consumers in terms of what the extra calorie intake implies in relation to activity levels. The present study aimed at providing more insight into consumers’ appreciation of front-of-pack labelling of caloric content of food products and their specific preferences for alternative execution formats for such information in Europe. Design For this purpose, eight executions of front-of-pack calorie flags were designed and their appeal and information value were extensively discussed with consumers through qualitative research in four different countries (Germany, The Netherlands, France and the UK). Results The results show that calories are well-understood and that participants were generally positive about front-of-pack flags, particularly when flags are uniform across products. The most liked flags are the simpler flags depicting only the number of calories per serving or per 100 g, while more complex flags including references to daily needs or exercise and the flag including a phrase referring to balanced lifestyle were least preferred. Some relevant differences between countries were observed. Although participants seem to be familiar with the notion of calories, they do not seem to fully understand how to apply them. Conclusion From the results, managerial implications for the design and implementation of front-of-pack calorie labelling as well as important directions for future research are discussed.

    Specific and highly efficient fluorescent labeling techniques for biomolecules, especially for proteins, are required for the quantitative analyses of bio-phenomena and for subsequent systems biology. Although expression of exogenous proteins fused with fluorescent tags, such as green fluorescent protein, is the most widely used method for quantitative bio-analysis, the following problems need to be considered carefully: (1) precise stoichiometric control in living cells is difficult, and (2) the bulkiness of the fluorescent tags restricts analysis of the inherent physical and biological properties of the proteins. Therefore, novel techniques to specifically and stoichiometrically label intrinsic proteins or other biomolecules in living cells should be developed. Click chemistry reactions (e.g., Huisgen cycloaddition and Staudinger ligation) are the most promising approaches for this purpose, because these chemical reactions have following advantages: (1) bioorthogonal reactions; (2) mild reaction conditions suitable for fragile biomolecules, cells, and tissues; (3) extremely high reaction ratio; (4) small size of the functional groups for the cross-coupling reactions; (5) stable covalent bonding; and (6) simple metabolic labeling procedures in living cells, using various biomolecular analogs. Diverse quantitative biological studies have been carried out using this technology (e.g., quantification of novel synthesized proteins and observation of post-translational modifications). In this review, I explain the basics of chemical probing with click chemistry, and discuss its recent applications in the field of quantitative biology. Furthermore, I discuss the capability, significance, and future of the chemical probing of proteins, with an emphasis on the use of click chemistry in the field of the quantitative biology.

    In this paper, the tunable multiple optical orthogonal codes sequences (MOOCS)-based optical label for optical packet switching (OPS) (MOOCS-OPS) is experimentally demonstrated for the first time. The tunable MOOCS-based optical label is performed by using fiber Bragg grating (FBG)-based optical en/decoders group and optical switches configured by using Field Programmable Gate Array (FPGA), and the optical label is erased by using Semiconductor Optical Amplifier (SOA). Some waveforms of the MOOCS-based optical label, optical packet including the MOOCS-based optical label and the payloads are obtained, the switching control mechanism and the switching matrix are discussed, the bit error rate (BER) performance of this system is also studied. These experimental results show that the tunable MOOCS-OPS scheme is effective.

    Nikol'skiĭ, D O; Timofeev, V P

    2003-01-01

    The method of spin labeling was used to monitor quick movements of side residues in protein monocrystals. The EPR spectra of monocrystals of spin-labeled lysozyme at different orientations of the tetrahonal crystal relative to the direction of the magnetic field were interpreted using the molecular dynamics method. A simple model was proposed, which enables one to calculate the trajectory of movements of the spin label by the molecular dynamic method over a relatively short period of time. The entire "frozen" protein molecule and a "defrozen" spin-labeled amino acid residue were considered in the framework of the model. To calculate the trajectories in vacuum, a model of spin-labeled lysozyme was constructed, and the parameters of force potentials for the atoms of the protein molecule and the spin label were specified. It follows from the calculations that the protein environment sterically hinders the range of eventual angular reorientations of the reporter NO-group of nitroxyl incorporated into the spin label, thereby affecting the shape of the EPR spectrum. However, the scatter in the positions of the reporter group in the angular space turned out to correspond to the Gauss distribution. Using the atomic coordinates of the spin label, obtained in a chosen time interval by the method of molecular dynamics, and taking into account the distribution of the states of the spin label in the ensemble of spin-labeled macromolecules in the crystal, we simulated the EPR spectra of monocrystals of spin-labeled lysozyme. The theoretical EPR spectra coincide well with the experimental.

    2016-05-01

    Precision medicine promises to improve both the efficacy and safety of therapeutic products by better informing why some patients respond well to a drug, and some experience adverse reactions, while others do not. Pharmacogenomics is a key component of precision medicine and can be utilized to select optimal doses for patients, more precisely identify individuals who will respond to a treatment and avoid serious drug-related toxicities. Since pharmacogenomic biomarker information can help inform drug dosing, efficacy, and safety, pharmacogenomic data are critically reviewed by FDA staff to ensure effective use of pharmacogenomic strategies in drug development and appropriate incorporation into product labels. Pharmacogenomic information may be provided in drug or biological product labeling to inform health care providers about the impact of genotype on response to a drug through description of relevant genomic markers, functional effects of genomic variants, dosing recommendations based on genotype, and other applicable genomic information. The format and content of labeling for biologic drugs will generally follow that of small molecule drugs; however, there are notable differences in pharmacogenomic information that might be considered useful for biologic drugs in comparison to small molecule drugs. Furthermore, the rapid entry of biologic drugs for treatment of rare genetic diseases and molecularly defined subsets of common diseases will likely lead to increased use of pharmacogenomic information in biologic drug labels in the near future. In this review, we outline the general principles of therapeutic product labeling and discuss the utilization of pharmacogenomic information in biologic drug labels.

    Energy labels on buildings are mandatory in Europe since 2006 with the application of the European directive 2002/91/CE on the energy performance of buildings. Therefore, it is relevant to analyse how the labels work in those countries that already have experiences with them. This article analyses how house owners have interpreted and used the knowledge from labels for the renovation of their house. The study is based on qualitative interviews with ten households having a Belgian volunteer energy assessment and ten households having the Danish mandatory energy label on their newly bought house. The article questions the faith in the rational enlightened actor, which is at the basis of the idea of labels. Using sociological theories on knowledge and everyday life in the interpretation of the qualitative material, it is shown that people relate to, interpret and question new knowledge rather than just take it in. Furthermore, it is also shown how the use of knowledge and advice interact with other priorities in everyday life. These results can help explain why people often do not carry through energy measures even though it might be economically advantageous to them. In the conclusion, it is also discussed how this type of knowledge might be used to improve energy labels. (author)

    Full Text Available OBJETIVO: Apresentar uma adaptação do Traffic Light Labelling, ou "Semáforo Nutricional", adotado no Reino Unido e outros países da Europa, às normas vigentes no Brasil e classificar produtos industrializados comercializados no país. MÉTODOS: Esta ferramenta baseia-se na utilização das cores do semáforo para valorar concentrações de gorduras total, saturada e trans, açúcar, sódio e fibra correspondente a 100g ou 100mL do produto. O sinal vermelho indica que o nutriente está presente em quantidade excessiva; o amarelo, média e o verde, adequada. Para fibras as baixas concentrações têm cor vermelha e as recomendadas, verde. A adaptação e aplicação desses conceitos para consumidores brasileiros fundamentaram-se nas normas do Regulamento Técnico Referente à Informação Nutricional Complementar da Agência Nacional de Vigilância Sanitária e da Food Standards Agency. RESULTADOS: Foram classificados cem produtos industrializados, os quais foram selecionados da página eletrônica de um hipermercado brasileiro, optando pelos primeiros cinco a oito produtos listados na página, para cada uma das 17 categorias. A análise mostra que são altas as quantidades de gordura total, saturada e sódio e baixas as quantidades de gordura trans e fibra. CONCLUSÃO: A adaptação dessa metodologia visa facilitar a escolha de alimentos saudáveis, sensibilizando os consumidores quanto às desvantagens no que se refere a qualidade nutricional dos alimentos industrializados, e estimular as indústrias a melhorar a composição nutricional de seus produtos, sob a perspectiva de receberem maior quantidade de sinais verdes e menor quantidade de sinais vermelhos; assim, contribuindo para a prevenção de erros alimentares, obesidade e doenças crônicas não-transmissíveis, principais causas de incapacidade e mortes precoces no Brasil.OBJECTIVE: This study presented an adaptation of the Traffic Light Labeling or Nutrition Traffic Light adopted

    2014-01-01

    Isotope labeling experiments (ILEs) offer a powerful methodology to perform metabolic flux analysis. However, the task of interpreting data from these experiments to evaluate flux values requires significant mathematical modeling skills. Toward this, this chapter provides background information and examples to enable the reader to (1) model metabolic networks, (2) simulate ILEs, and (3) understand the optimization and statistical methods commonly used for flux evaluation. A compartmentalized model of plant glycolysis and pentose phosphate pathway illustrates the reconstruction of a typical metabolic network, whereas a simpler example network illustrates the underlying metabolite and isotopomer balancing techniques. We also discuss the salient features of commonly used flux estimation software 13CFLUX2, Metran, NMR2Flux+, FiatFlux, and OpenFLUX. Furthermore, we briefly discuss methods to improve flux estimates. A graphical checklist at the end of the chapter provides a reader a quick reference to the mathematical modeling concepts and resources.

  3. A Labeling Model Based on the Region of Movability for Point-Feature Label Placement

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Automatic point-feature label placement (PFLP is a fundamental task for map visualization. As the dominant solutions to the PFLP problem, fixed-position and slider models have been widely studied in previous research. However, the candidate labels generated with these models are set to certain fixed positions or a specified track line for sliding. Thus, the whole surrounding space of a point feature is not sufficiently used for labeling. Hence, this paper proposes a novel label model based on the region of movability, which comes from plane collision detection theory. The model defines a complete conflict-free search space for label placement. On the premise of no conflict with the point, line, and area features, the proposed model utilizes the surrounding zone of the point feature to generate candidate label positions. By combining with heuristic search method, the model achieves high-quality label placement. In addition, the flexibility of the proposed model enables placing arbitrarily shaped labels.

    Nutritional labelling of packaged foods, mandated by law, includes details of the food content and composition - information that can affect individual and public lifestyle decisions and health status. We studied the comprehension of food labels among 120 young adults (mean age 24.1 years) attending an international travel immunization clinic. Each participant was presented with 10 food packages of common local products and was interviewed regarding the label's content. Most subjects (77.5%) reported that they took note of the food labels; women, the more educated and those engaging regularly in physical exercise were more inclined to do so. Out of a possible 10 points the overall median comprehension score was 6.0 (mean 5.7±1.8). The nutritional table section of the food label was understood the best, and the nutritional declaration section the least. The subjects thought they understood the food labels better than they actually did; 43.9% stated that they understood them very well, whereas only 27.2% achieved high scores. This inadequate comprehension of food labels represents a missed opportunity to provide essential information necessary for healthy food choices at the individual level. A combination of strategies is necessary, including improving food labels (simplification and standardization) combined with targeted educational programs. Copyright © 2011 Elsevier Ltd.

    In this paper, we propose a new form of regularization that is able to utilize the label information of a data set for learning kernels. The proposed regularization, referred to as ideal regularization, is a linear function of the kernel matrix to be learned. The ideal regularization allows us to develop efficient algorithms to exploit labels. Three applications of the ideal regularization are considered. Firstly, we use the ideal regularization to incorporate the labels into a standard kernel, making the resulting kernel more appropriate for learning tasks. Next, we employ the ideal regularization to learn a data-dependent kernel matrix from an initial kernel matrix (which contains prior similarity information, geometric structures, and labels of the data). Finally, we incorporate the ideal regularization to some state-of-the-art kernel learning problems. With this regularization, these learning problems can be formulated as simpler ones which permit more efficient solvers. Empirical results show that the ideal regularization exploits the labels effectively and efficiently.

    The spinal column constitutes the central axis of human torso and is often used by radiologists to reference the location of organs in the chest and abdomen. However, visually identifying and labeling vertebrae is not trivial and can be timeconsuming. This paper presents an approach to automatically label vertebrae based on two pieces of anatomical knowledge: one vertebra has at most two attached ribs, and ribs are attached only to thoracic vertebrae. The spinal column is first extracted by a hybrid method using the watershed algorithm, directed acyclic graph search and a four-part vertebra model. Then curved reformations in sagittal and coronal directions are computed and aggregated intensity profiles along the spinal cord are analyzed to partition the spinal column into vertebrae. After that, candidates for rib bones are detected using features such as location, orientation, shape, size and density. Then a correspondence matrix is established to match ribs and vertebrae. The last vertebra (from thoracic to lumbar) with attached ribs is identified and labeled as T12. The rest of vertebrae are labeled accordingly. The method was tested on 50 CT scans and successfully labeled 48 of them. The two failed cases were mainly due to rudimentary ribs.

    In their proposals for revision of the energy labelling directive the European Commission has suggested to include windows. The paper introduces a proposal for an European energy labelling scheme of windows for replacement of windows in the existing building stock taking into consideration the energy performance of windows in both the heating and cooling seasons. The labelling scheme evaluates a methodology where the energy performance in the heating period is established with focus on heat loss and utilization of passive solar energy, whereas the energy performance in the summer (cooling) season will focus on reduction of solar radiation into the building. The methodology is developed with focus on CEN and ISO standardization. With inspiration from the American Energy Star programme for windows, Europe is divided into climate zones where the methodology for each zone is developed on basis of a reference building and climate data. A proposal for labelling will be presented for both heating and cooling seasons in order to enable the user to choose the right product for a specific performance. Based on data from the building stock in the individual climate zones, an energy saving potential for replacement of old windows with new low energy windows will be presented. The possibility for using energy labelling of windows as reference and requirement in the building legislation as an alternative to U-values, will be presented with among others examples from legislation in UK and Denmark.

    During the fall of 1996, the Interstate Oil and Gas Compact Commission sponsored sessions for government and industry representatives to discuss concerns about the National Pollution Discharge Elimination System (NPDES) program under the Clean Water Act. In January 1997, the NPDES Education/Communication/Training Workgroup (ECT Workgroup) was established with co-leaders from the Environmental Protection Agency (EPA) and industry. The ECT Workgroup`s purpose was to develop ideas that would improve communication between NPDES regulators and the oil and gas industry regarding NPDES compliance issues. The Workgroup focused on several areas, including permit compliance monitoring and reporting, enforcement activity and options, and treatment technology. The ECT Workgroup also discussed the need for materials and information to help NPDES regulatory agency personnel understand more about oil and gas industry exploration and extraction operations and treatment processes. This report represents a compendium of the ECT Workgroup`s efforts.

  11. Studying lipid-protein interactions with electron paramagnetic resonance spectroscopy of spin-labeled lipids.

    Páli, Tibor; Kóta, Zoltán

    2013-01-01

    Spin label electron paramagnetic resonance (EPR) of lipid-protein interactions reveals crucial features of the structure and assembly of integral membrane proteins. Spin label EPR spectroscopy is the technique of choice to characterize the protein-solvating lipid shell in its highly dynamic nature, because the EPR spectra of lipids that are spin labeled close to the terminal methyl end of their acyl chains display two spectral components, those corresponding to lipids directly contacting the protein and those corresponding to lipids in the bulk fluid bilayer regions of the membrane. In this chapter, typical spin label EPR procedures are presented that allow determination of the stoichiometry of interaction of spin-labeled lipids with the intra-membranous region of membrane proteins or polypeptides, as well as the association constant of the spin-labeled lipid with respect to the host lipid. The lipids giving rise to the so-called immobile spectral component in the EPR spectrum of such samples are identified as the motionally restricted first-shell lipids solvating membrane proteins in biomembranes. Stoichiometry and selectivity are directly related to the structure of the intra-membranous sections of membrane-associated proteins or polypeptides and can be used to study the state of assembly of such proteins in the membrane. Since these characteristics of lipid-protein interactions are discussed in detail in the literature [see Marsh (Eur Biophys J 39:513-525, 2010) for a most recent review], here we focus more on how to spin label model and biomembranes and how to measure and analyze the two-component EPR spectra of spin-labeled lipids in phospholipid bilayers that contain proteins or polypeptides. After a description of how to prepare spin-labeled model and native biological membranes, we present the reader with computational procedures for determining the molar fraction of motionally restricted lipids when both, one, or none of the pure isolated-mobile or

    The present paper discuss a novel method of tagging and labeling of waste casks, copper canisters, spent fuel containers, mercury containers, waste pack- ages and other items. In particular, it is related to the development of new long-term security identification tags/labels that can be applied to articles for carrying information about the content, inventory tracking, prevention of falsifi- cation and theft etc. It is suggested to use a unique combination of radioisotopes with different predictable length of life, as a label of the items. The possibil- ity to realize a multidimensional bar code symbology is proposed as an option for a new labeling method. The results of the first tests and evaluations of this are shown and discussed in the paper. The invention is suitable for use in items assigned to long-term (hundreds of years) storing or for final repositories. Alternative field of use includes fresh nuclear fuel handling and shipment of goods.

    Full Text Available This work presents an analysis of ecological certification and labelling in the field of tourism. In a tourist company, the certification schemes evaluate the general approach of environmental problems, and impose to the tourist services the observance of pre-established principles and guiding lines concerning the environment. They become for the tourist companies a behavioural standard in the development of their activity. The requirements within such schemes are often flexible and open to interpretation, and generally less controversial than the eco-labelling schemes. As compared to the certification schemes, the eco-labels attributed to the tourist services emphasise the impact over the environment of the services of tourist companies, on the basis of certain European criteria. These criteria refer to the whole life cycle of these tourist services.

    Full Text Available Susanne B Haga, Rachel Mills, Jivan Moaddeb Center for Applied Genomics and Precision Medicine, Department of Medicine, Duke University, Durham, NC, USA Abstract: Advances in pharmacogenetic research have improved our understanding of adverse drug responses and have led to the development of pharmacogenetic tests and targeted drugs. However, the extent of the communication process and provision of information to patients about pharmacogenetics is unclear. Pharmacogenetic information may be included in sections of a drug's package insert intended for patients, which is provided directly to patients or communicated via the health provider. To determine what pharmacogenetic information, if any, is included in patient-targeted sections of the drug label, we reviewed the labels listed in the US Food and Drug Administration's Table of Pharmacogenomic Biomarkers in Drug Labels. To date, 140 drugs include pharmacogenetic-related information in the approved label. Our analysis revealed that pharmacogenetic information is included in patient-targeted sections for a minority (n=29; 21% of drug labels, with no obvious pattern associated with the inclusion of pharmacogenetic information. Therefore, patients are unlikely to learn about pharmacogenetics through written materials dispensed with the drug. Given that there are also inconsistencies with regard to inclusion of pharmacogenetic information in the patient counseling information section, it is also unlikely that patients are receiving adequate pharmacogenetic information from their provider. The inconsistent presence of pharmacogenetic information in patient-targeted sections of drug labels suggests a need to review the criteria for inclusion of information in patient-targeted sections in order to increase consistency and patient knowledge of pharmacogenetic information.

  19. Visualizing dengue virus through Alexa Fluor labeling.

    The early events in the interaction between virus and cell can have profound influence on the outcome of infection. Determining the factors that influence this interaction could lead to improved understanding of disease pathogenesis and thus influence vaccine or therapeutic design. Hence, the development of methods to probe this interaction would be useful. Recent advancements in fluorophores development and imaging technology can be exploited to improve our current knowledge on dengue pathogenesis and thus pave the way to reduce the millions of dengue infections occurring annually. The enveloped dengue virus has an external scaffold consisting of 90 envelope glycoprotein (E) dimers protecting the nucleocapsid shell, which contains a single positive strand RNA genome. The identical protein subunits on the virus surface can thus be labeled with an amine reactive dye and visualized through immunofluorescent microscopy. Here, we present a simple method of labeling of dengue virus with Alexa Fluor succinimidyl ester dye dissolved directly in a sodium bicarbonate buffer that yielded highly viable virus after labeling. There is no standardized procedure for the labeling of live virus and existing manufacturer's protocol for protein labeling usually requires the reconstitution of dye in dimethyl sulfoxide. The presence of dimethyl sulfoxide, even in minute quantities, can block productive infection of virus and also induce cell cytotoxicity. The exclusion of the use of dimethyl sulfoxide in this protocol thus reduced this possibility. Alexa Fluor dyes have superior photostability and are less pH-sensitive than the common dyes, such as fluorescein and rhodamine, making them ideal for studies on cellular uptake and endosomal transport of the virus. The conjugation of Alexa Fluor dye did not affect the recognition of labeled dengue virus by virus-specific antibody and its putative receptors in host cells. This method could have useful applications in virological studies.

    Health literacy has increasingly been viewed as a patient safety issue and may contribute to medication errors. To examine patients' abilities to understand and demonstrate instructions found on container labels of common prescription medications. Cross-sectional study using in-person, structured interviews. 3 primary care clinics serving mostly indigent populations in Shreveport, Louisiana; Jackson, Michigan; and Chicago, Illinois. 395 English-speaking adults waiting to see their providers. Correct understanding of instructions on 5 container labels; demonstration of 1 label's dosage instructions. Correct understanding of the 5 labels ranged from 67.1% to 91.1%. Patients reading at or below the sixth-grade level (low literacy) were less able to understand all 5 label instructions. Although 70.7% of patients with low literacy correctly stated the instructions, "Take two tablets by mouth twice daily," only 34.7% could demonstrate the number of pills to be taken daily. After potential confounding variables were controlled for, low (adjusted relative risk, 2.32 [95% CI, 1.26 to 4.28]) and marginal (adjusted relative risk, 1.94 [CI, 1.14 to 3.27]) literacy were significantly associated with misunderstanding. Taking a greater number of prescription medications was also statistically significantly associated with misunderstanding (adjusted relative risk, 2.98 [CI, 1.40 to 6.34] for > or =5 medications). The study sample was at high risk for poor health literacy and outcomes. Most participants were women, and all spoke English. The authors did not examine the association between misunderstanding and medication error or evaluate patients' actual prescription drug-taking behaviors. Lower literacy and a greater number of prescription medications were independently associated with misunderstanding the instructions on prescription medication labels.

    2011-01-01

    Geometric objects are often represented approximately in terms of a finite set of points in three-dimensional euclidean space. In this paper, we extend this representation to what we call labeled point clouds. A labeled point cloud is a finite set of points, where each point is not only associated with a position in three-dimensional space, but also with a discrete class label that represents a specific property. This type of model is especially suitable for modeling biomolecules such as proteins and protein binding sites, where a label may represent an atom type or a physico-chemical property. Proceeding from this representation, we address the question of how to compare two labeled points clouds in terms of their similarity. Using fuzzy modeling techniques, we develop a suitable similarity measure as well as an efficient evolutionary algorithm to compute it. Moreover, we consider the problem of establishing an alignment of the structures in the sense of a one-to-one correspondence between their basic constituents. From a biological point of view, alignments of this kind are of great interest, since mutually corresponding molecular constituents offer important information about evolution and heredity, and can also serve as a means to explain a degree of similarity. In this paper, we therefore develop a method for computing pairwise or multiple alignments of labeled point clouds. To this end, we proceed from an optimal superposition of the corresponding point clouds and construct an alignment which is as much as possible in agreement with the neighborhood structure established by this superposition. We apply our methods to the structural analysis of protein binding sites.

    Reducing marine-based public health risk requires strict control of several attributes of seafood products, often including location and conditions of catch or aquaculture, processing, and handling throughout the supply chain. Buyers likely will also be interested in other attributes of these products such as eco-friendliness or taste. Development of markets for improved safety, as well as for other quality attributes, requires an effective certification and tracking of these attributes as well as their communication to buyers. Several challenges must be met if labeling, particularly consumer labeling, is to support the development of markets for improved seafood safety.

    In summary, the ability to generate NMR quantities of {sup 15}N and {sup 13}C-labeled RNAs has led to the development of heteronuclear multi-dimensional NMR techniques for simplifying the resonance assignment and structure determination of RNAs. These methods for synthesizing isotopically labeled RNAs are only several years old, and thus there are still relatively few applications of heteronuclear multi-dimensional NMR techniques to RNA. However, given the critical role that RNAs play in cellular function, one can expect to see an increasing number of NMR structural studies of biologically active RNAs.

    The use of high dose baclofen for alcohol-dependence emerged in France from 2008 based on empirical findings, and is still off-label. However, due to the rapid increase in this prescribing practice, the French health authorities have decided to frame it using an extraordinary regulatory measure named "temporary recommendation for use" (TRU). Baclofen prescribers from CAMTEA, a regional team-based off-label system for supervising baclofen prescribing, which was developed much prior to the TRU, discuss herein the pros and cons of this measure and the applicability of its different aspects in the daily clinical practice.

  14. Are Luxury Brand Labels and "Green" Labels Costly Signals of Social Status? An Extended Replication.

    Science.gov (United States)

    Berger, Joël

    2017-01-01

    Costly signaling theory provides an explanation for why humans are willing to a pay a premium for conspicuous products such as luxury brand-labeled clothing or conspicuous environmentally friendly cars. According to the theory, the extra cost of such products is a signal of social status and wealth and leads to advantages in social interactions for the signaler. A previous study found positive evidence for the case of luxury brand labels. However, an issue of this study was that some of the experiments were not conducted in a perfectly double-blind manner. I resolved this by replicating variations of the original design in a double-blind procedure. Additionally, besides the luxury label condition, I introduced a "green" label condition. Thus, the hypothesis that signaling theory is able to explain pro-environmental behavior was tested for the first time in a natural field setting. Further, I conducted experiments in both average and below-average socioeconomic neighborhoods, where, according to signaling theory, the effects of luxury signals should be even stronger. In contrast to the original study, I did not find positive effects of the luxury brand label in any of the five experiments. Nor did I find evidence for a green-signaling effect. Moreover, in poor neighborhoods a negative tendency of the luxury label actually became evident. This suggests that a signaling theory explanation of costly labels must take into account the characteristics of the observers, e.g. their social status.

    In recent years, optical label switching (OLS) gains lots of attentions due to its intrinsic advantages to implement protocol, bit-rate, granularity and data format transparency packet switching. In this paper, we propose a novel scheme to realize flexible-rate optical packet switching for OLS networks. At the transmitter node, flexible-rate packet is generated by parallel modulating different combinations of optical carriers generated from the optical multi-carrier generator (OMCG), among which the low-speed optical label occupies one carrier. At the switching node, label is extracted and re-generated in label processing unit (LPU). The payloads are switched based on routing information and new label is added after switching. At the receiver node, another OMCG serves as local oscillators (LOs) for optical payloads coherent detection. The proposed scheme offers good flexibility for dynamic optical packet switching by adjusting the payload bandwidth and could also effectively reduce the number of lasers, modulators and receivers for packet generation/detection. We present proof-of-concept demonstrations of flexible-rate packet generation/detection and label swapping in 12.5 GHz grid. The influence of crosstalk for cascaded label swapping is also investigated.

  18. Efficient Thread Labeling for Monitoring Programs with Nested Parallelism

    Science.gov (United States)

    Ha, Ok-Kyoon; Kim, Sun-Sook; Jun, Yong-Kee

    It is difficult and cumbersome to detect data races occurred in an execution of parallel programs. Any on-the-fly race detection techniques using Lamport's happened-before relation needs a thread labeling scheme for generating unique identifiers which maintain logical concurrency information for the parallel threads. NR labeling is an efficient thread labeling scheme for the fork-join program model with nested parallelism, because its efficiency depends only on the nesting depth for every fork and join operation. This paper presents an improved NR labeling, called e-NR labeling, in which every thread generates its label by inheriting the pointer to its ancestor list from the parent threads or by updating the pointer in a constant amount of time and space. This labeling is more efficient than the NR labeling, because its efficiency does not depend on the nesting depth for every fork and join operation. Some experiments were performed with OpenMP programs having nesting depths of three or four and maximum parallelisms varying from 10,000 to 1,000,000. The results show that e-NR is 5 times faster than NR labeling and 4.3 times faster than OS labeling in the average time for creating and maintaining the thread labels. In average space required for labeling, it is 3.5 times smaller than NR labeling and 3 times smaller than OS labeling.

  2. Pitch memory, labelling and disembedding in autism.

    Science.gov (United States)

    Heaton, Pamela

    2003-05-01

    Autistic musical savants invariably possess absolute pitch ability and are able to disembed individual musical tones from chords. Enhanced pitch discrimination and memory has been found in non-savant individuals with autism who also show superior performance on visual disembedding tasks. These experiments investigate the extent that enhanced disembedding ability will be found within the musical domain in autism. High-functioning children with autism, together with age- and intelligence-matched controls, participated in three experiments testing pitch memory, labelling and chord disembedding. The findings from experiment 1 showed enhanced pitch memory and labelling in the autism group. In experiment 2, when subjects were pre-exposed to labelled individual tones, superior chord segmentation was also found. However, in experiment 3, when disembedding performance was less reliant on pitch memory, no group differences emerged and the children with autism, like controls, perceived musical chords holistically. These findings indicate that pitch memory and labelling is superior in autism and can facilitate performance on musical disembedding tasks. However, when task performance does not rely on long-term pitch memory, autistic children, like controls, succumb to the Gestalt qualities of chords.

  12. Microfluidic Radiometal Labeling Systems for Biomolecules

    Energy Technology Data Exchange (ETDEWEB)

    Reichert, D E; Kenis, P J. A.

    2011-12-29

    In a typical labeling procedure with radiometals, such as Cu-64 and Ga-68; a very large (~ 100-fold) excess of the non-radioactive reactant (precursor) is used to promote rapid and efficient incorporation of the radioisotope into the PET imaging agent. In order to achieve high specific activities, careful control of reaction conditions and extensive chromatographic purifications are required in order to separate the labeled compounds from the cold precursors. Here we propose a microfluidic approach to overcome these problems, and achieve high specific activities in a more convenient, semi-automated fashion and faster time frame. Microfluidic reactors, consisting of a network of micron-sized channels (typical dimensions in the range 10 - 300¼m), filters, separation columns, electrodes and reaction loops/chambers etched onto a solid substrate, are now emerging as an extremely useful technology for the intensification and miniaturization of chemical processes. The ability to manipulate, process and analyze reagent concentrations and reaction interfaces in both space and time within the channel network of a microreactor provides the fine level of reaction control that is desirable in PET radiochemistry practice. These factors can bring radiometal labeling, specifically the preparation of radio-labeled biomolecules such as antibodies, much closer to their theoretical maximum specific activities.

    The techniques for image analysis and classification generally consider the image sample labels fixed and without uncertainties.The rank regression problem studied in this paper is based on the training samples with uncertain labels,which often is the case for the manual estimated image labels.A core ranking model is designed first as the bilinear fusing of multiple candidate kernels.Then,the parameters for feature selection and kernel selection are learned simultaneously by maximum a posteriori for given samples and uncertain labels.The provable convergency Expectation Maximization(EM)method is used for inferring these parameters in an iterative manner.The effectiveness of the proposed algorithm is finally validated by the extensive experiments on age ranking task and human trackingtask.The popular FG-NET and the large scale Yamaha aging database are used for the age estimation experiments,and our algorithm outperforms those state-of-the-art algorithms ever reported by other interrelated literatures significantly.The experiment result of human tracking task also validates its advantage over conventional linear regression algorithm.

    Goddard, Julie M; Mandal, Sudeep; Nugen, Sam R; Baeumner, Antje J; Erickson, David

    2010-03-01

    We present a biopatterning technique suitable for applications which demand a high degree of surface cleanliness, such as immobilization of biological recognition elements onto label-free biosensors. In the case of label-free biosensing, the mechanism of signal transduction is based on surface bound matter, making them highly sensitive to surface contamination including residues left during the biopatterning process. In this communication we introduce a simple, rapid processing step that removes 98% of the residues that often remain after standard parylene lift-off patterning. Residue-free parylene biopatterning is combined with microfluidics to localize biomolecule immobilization onto the sensing region and to enable multiplexed biopatterning. We demonstrate the applicability of this method to multiplexed label-free detection platforms by patterning nucleic acid capture probes corresponding to the four different serotypes of Dengue virus onto parallel 1D photonic crystal resonator sensors. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) are used to quantify surface cleanliness and uniformity. In addition to label-free biosensors, this technique is well suited to other nanobiotechnology patterning applications which demand a pristine, residue-free surface, such as immobilization of enzymes, antibodies, growth factors, or cell cultures.

  9. Generating Realistic Labelled, Weighted Random Graphs

    Directory of Open Access Journals (Sweden)

    Michael Charles Davis

    2015-12-01

    Full Text Available Generative algorithms for random graphs have yielded insights into the structure and evolution of real-world networks. Most networks exhibit a well-known set of properties, such as heavy-tailed degree distributions, clustering and community formation. Usually, random graph models consider only structural information, but many real-world networks also have labelled vertices and weighted edges. In this paper, we present a generative model for random graphs with discrete vertex labels and numeric edge weights. The weights are represented as a set of Beta Mixture Models (BMMs with an arbitrary number of mixtures, which are learned from real-world networks. We propose a Bayesian Variational Inference (VI approach, which yields an accurate estimation while keeping computation times tractable. We compare our approach to state-of-the-art random labelled graph generators and an earlier approach based on Gaussian Mixture Models (GMMs. Our results allow us to draw conclusions about the contribution of vertex labels and edge weights to graph structure.

  15. Nutrition labelling is a trade policy issue: lessons from an analysis of specific trade concerns at the World Trade Organization.

    Interpretive nutrition labels provide simplified nutrient-specific text and/or symbols on the front of pre-packaged foods, to encourage and enable consumers to make healthier choices. This type of labelling has been proposed as part of a comprehensive policy response to the global epidemic of non-communicable diseases. However, regulation of nutrition labelling falls under the remit of not just the health sector but also trade. Specific Trade Concerns have been raised at the World Trade Organization's Technical Barriers to Trade Committee regarding interpretive nutrition labelling initiatives in Thailand, Chile, Indonesia, Peru and Ecuador. This paper presents an analysis of the discussions of these concerns. Although nutrition labelling was identified as a legitimate policy objective, queries were raised regarding the justification of the specific labelling measures proposed, and the scientific evidence for effectiveness of such measures. Concerns were also raised regarding the consistency of the measures with international standards. Drawing on policy learning theory, we identified four lessons for public health policy makers, including: strategic framing of nutrition labelling policy objectives; pro-active policy engagement between trade and health to identify potential trade issues; identifying ways to minimize potential 'practical' trade concerns; and engagement with the Codex Alimentarius Commission to develop international guidance on interpretative labelling. This analysis indicates that while there is potential for trade sector concerns to stifle innovation in nutrition labelling policy, care in how interpretive nutrition labelling measures are crafted in light of trade commitments can minimize such a risk and help ensure that trade policy is coherent with nutrition action. © The Author 2017.

    Metabolic labeling of biomolecules with bioorthogonal functionalities enables visualization, enrichment, and analysis of the biomolecules of interest in their physiological environments. This versatile strategy has found utility in probing various classes of biomolecules in a broad range of biological processes. On the other hand, metabolic labeling is nonselective with respect to cell type, which imposes limitations for studies performed in complex biological systems. Herein, we review the recent methodological developments aiming to endow metabolic labeling strategies with cell-type selectivity. The cell-selective metabolic labeling strategies have emerged from protein and glycan labeling. We envision that these strategies can be readily extended to labeling of other classes of biomolecules.

    Raloxifene, [6-hydroxy-2-(4-hydroxy-phenyl) benzo [b] thiophen-3-yl]-[4-(2-piperidin-1-yl-ethoxy)phenyl] methanone, a tissue-selective estrogen mixed agonist/antagonist, classified as a selective estrogen receptor modulator (SERM), is currently under clinical evaluation for the prevention and treatment of postmenopausal osteoporosis, breast cancer, uterine dysfunction, and other disorders of the female reproductive system. Based on SAR studies of substituted raloxifenes, we synthesized 3 kinds of fluoroalkylated raloxifene derivatives. These compounds show high relative binding affinities (RBA) to the estrogen receptor in vitro (RBA of estradiol = 100%). The RBA values for compounds 1, 2 and 3 are 89, 60, and 45%, respectively, which are all higher than that of raloxifene itself (34%). Among these compounds, we selected to take the best RBA value one and F-18 labeled. Using 2 kinds of labeling method ; 1) Radiolabeling using [{sup 18}F]KF was carried out in anhydrous acetonitrile for 10 min at 120 .deg. C. 2) Radiolabeling using [{sup 18}F]KF was carried out in anhydrous acetonitrile for 15 min at 120 .deg. C in ionic liquid, [bmim][OTf]. Deprotection step added 1N HCl and reacted for 3 min at 120 .deg. C. [{sup 18}F]Fluoroethyl raloxifene derivative obtained 5-23% decay corrected labeling yield by HPLC system (C18 xterra, 10 i, 34% Acetonitrile/0.1 M formate buffer, flow rate: 4 mL/1 min, collection time : 28-29 min) and total time was around 70 min. Fluoroethyl raloxifene derivative has the best RBA value among the other synthesized derivatives and chose it for radiolabeling. [{sup 18}F]Fluoroethyl raloxifene derivative prepared 5-23% decay corrected labeling yield. This preparation is on going for labeling optimizing and preparing of in vitro and in vivo test.

    Current interest in the use of heteronuclear multidimensional NMR methods to assess the structures, conformations and/or dynamics of oligonucleotides in solution has created an immediate need for nucleosides and their derivatives labeled in various ways with stable isotopes (13C, 2H, 15N and/or 17,18O). This short review focuses exclusively on chemienzymic methods to introduce one or more 13C labels into D-ribose, a precursor to ribo- and 2'-deoxyribonucleosides. It will be demonstrated that five convenient reactions, applied in specific sequences, provide access to 26 of the 32 13C-labeled isotopomers of D-ribose in acceptable yields. While not explicitly discussed herein, these same reactions, appropriately modified, can also be used to insert one or more 2H and/or 17,18O isotopes into this aldopentose.

    N-E-labeled calculus is a generalization of N-labeled calculus so as to describe time-concerned recog-nition, knowledge, belief and decision of humans or com-puter programs together with related external physical or logical phenomena. N-labeled calculus is the smallest for-mal system applicable to verification and analysis of coop-erative real-timing systems on natural number time introduced as an adaptation of tense arithmetic (TA). A merging problem of vehicles with misunderstanding or incorrect recognition is discussed as an example of coop-erating systems controlling continuously changing objects including human factor. Euler's approximation is intro-duced in order to represent the continuously changing objects. Through this example, relationship among arti-ficial intelligence, external environment and human fac-tors is investigated.

    2015-01-01

    The "field," "discipline," and "profession"--three major labels of emergency management--have often been interchanged as if any of these define the others. In this work, the authors examine these major labels to provide meaning, explanation, and application to each one based on the emergency management literature currently available. The authors accomplish this by the following: 1) defining and describing the established field's progression through the years; 2) examining how close we are to a discipline in today's emergency management arena; 3) discussing the advancement to becoming a profession; and 4) providing recommendations for the future. Clarifying these three major labels, the development of the field into a formidable and mature discipline as well as a distinguished and noble profession may be hastened.

    Full Text Available Saving energy is an important pillar for the mitigation of climate change. Electric devices (e.g., freezer and television are an important player in the residential sector in the final demand for energy. Consumers' purchase decisions are therefore crucial to successfully reach the energy-efficiency goals. Putting energy labels on products is often considered an adequate way of empowering consumers to make informed purchase decisions. Consequently, this approach should contribute to reducing overall energy consumption. The effectiveness of its measurement depends on consumers' use and interpretation of the information provided. Despite advances in energy efficiency and a mandatory labeling policy, final energy consumption per capita is in many countries still increasing. This paper provides a systematic analysis of consumers' reactions to one of the most widely used eco-labels, the European Union (EU energy label, by using eye-tracking methodology as an objective measurement. The study's results partially support the EU's mandatory policy, showing that the energy label triggers attention toward energy information in general. However, the energy label's effect on consumers' actual product choices seems to be rather low. The study's results show that the currently used presentation format on the label is insufficient. The findings suggest that it does not facilitate the integration of energy-related information. Furthermore, the current format can attract consumers to focus more on energy-efficiency information, leading them to disregard information about actual energy consumption. As a result, the final energy consumption may increase because excellent ratings on energy efficiency (e.g., A++ do not automatically imply little consumption. Finally, implications for policymakers and suggestions for further research are discussed.

  7. Glycemic index claims on food labels: review of Health Canada's evaluation.

    Wolever, T M S

    2013-12-01

    Recently Health Canada (HC) published its opinion that including glycemic index (GI) values on food labels would be misleading and not add value to nutrition labeling and dietary guidelines to help consumers make healthier food choices. Important areas of concern were identified by HC, but the discussion of them is scientifically invalid. HC concluded that GI has poor precision for labeling purposes based on incorrect application of the standard deviation. In fact, GI methodology is precise enough to distinguish, with high probability, low-GI (GI ≤ 55) from high-GI (GI ≥ 70) foods and to pass the Canadian Food Inspection Agency Nutrition Compliance Test procedure. HC rightly concluded that GI does not respond to portion size, whereas glycemic response does, but no valid evidence was provided to support the assertion that a lower-GI food could have a higher glycemic response. HC's focus on glycemic response could promote a low-carbohydrate diet inconsistent with nutrition recommendations. HC correctly concluded that GI is unresponsive to the replacement of available- with unavailable-carbohydrate but this is irrelevant to GI labeling. HC is rightly concerned about promoting unhealthy low-GI foods; however, this could be avoided by prohibiting GI labeling on such foods. Therefore, HC has provided neither a helpful nor scientifically valid evaluation of GI for labeling purposes but has contributed to the wealth of misinformation about GI in the literature. Currently, Canadian consumers only have access to unregulated and misleading information about GI; well-crafted guidelines for GI labeling would provide consumers accurate information about GI and help them make healthier food choices.

  8. Obesity prevention and personal responsibility: the case of front-of-pack food labelling in Australia

    2010-11-01

    Full Text Available Abstract Background In Australia, the food industry and public health groups are locked in serious struggle for regulatory influence over the terms of front-of-pack food labelling. Clear, unambiguous labelling of the nutritional content of pre-packaged foods and of standardized food items sold in chain restaurants is consistent with the prevailing philosophy of 'personal responsibility'. An interpretive, front-of-pack labelling scheme has the capacity to encourage healthier patterns of eating, and to be a catalyst for improvements in the nutritional quality of food products through re-formulation. On the other hand, the strength of opposition of the Australian Food and Grocery Council to 'Traffic Light Labelling', and its efforts to promote a non-interpretive, voluntary scheme, invite the interpretation that the food industry is resistant to any reforms that could destabilise current (unhealthy purchasing patterns and the revenues they represent. Discussion This article argues that although policies that aim to educate consumers about the nutritional content of food are welcome, they are only one part of a broader basket of policies that are needed to make progress on obesity prevention and public health nutrition. However, to the extent that food labelling has the capacity to inform and empower consumers to make healthier choices - and to be a catalyst for improving the nutritional quality of commercial recipes - it has an important role to play. Furthermore, given the dietary impact of meals eaten in fast food and franchise restaurants, interpretive labelling requirements should not be restricted to pre-packaged foods. Summary Food industry resistance to an interpretive food labelling scheme is an important test for government, and a case study of how self-interest prompts industry to promote weaker, voluntary schemes that pre-empt and undermine progressive public health regulation.

  9. Spectroscopic Methods for Label-Free Optical Nanoscopy

    Science.gov (United States)

    Chandler, John E.

    It is becoming increasingly evident that the nanoscale organization and structure of macromolecules play a significant role in determining the function and properties of biological systems. To understand the relationships between biological structure and function at nanometer length scales, there is a need for methods which enable imaging of intact nanoscale biological structure. An ideal technique for these applications is sensitive to nanoscale structure below the resolution limit of conventional optical microscopy ( 200 nm), achieves label-free contrast, is non-perturbing to biological samples, is quantitative, is capable of molecular specificity, is high-throughput, and finally is simple, enabling widespread utilization. Existing techniques meet some of these criteria, but all have limitations. For example, super-resolution optical microscopy methods achieve molecular-specific nanoscale resolution well below the resolution limit of conventional optical microscopes, however, they rely on fluorescent labels often at high densities that can be toxic and can often require potentially damaging illumination intensities for imaging. As a result, there remains a need for label-free optical techniques to study the nanoscale structural properties of cells. To address this need, the development of instrumentation and algorithms for Partial Wave Spectroscopic (PWS) microscopy will be described. PWS is a spectroscopic, label-free, nanoscale sensitive microscope which, senses rather than resolves structure below the resolution limit of conventional microscopes ( 200nm). First, PWS has shown utility as a diagnostic screening tool for cancer due to nanoscale structural alterations that occur in cells as part of the earliest stages of carcinogenesis. Instrumentation and algorithms developed to enable high-throughput cancer screening applications will be described. Further enhancement of data acquisition and analysis speed will then be described through the development of new

    Labeling connected components and holes and computing the Euler number in a binary image are necessary for image analysis,pattern recognition,and computer (robot) vision,and are usually made independently of each other in conventional methods.This paper proposes a two-scan algorithm for labeling connected components and holes simultaneously in a binary image by use of the same data structure.With our algorithm,besides labeling,we can also easily calculate the number and the area of connected components and holes,as well as the Euler number.Our method is very simple in principle,and experimental results demonstrate that our method is much more efficient than conventional methods for various kinds of images in cases where both labeling and Euler number computing are necessary.

  11. Facial Action Unit Recognition under Incomplete Data Based on Multi-label Learning with Missing Labels

    KAUST Repository

    Li, Yongqiang

    2016-07-07

    Facial action unit (AU) recognition has been applied in a wild range of fields, and has attracted great attention in the past two decades. Most existing works on AU recognition assumed that the complete label assignment for each training image is available, which is often not the case in practice. Labeling AU is expensive and time consuming process. Moreover, due to the AU ambiguity and subjective difference, some AUs are difficult to label reliably and confidently. Many AU recognition works try to train the classifier for each AU independently, which is of high computation cost and ignores the dependency among different AUs. In this work, we formulate AU recognition under incomplete data as a multi-label learning with missing labels (MLML) problem. Most existing MLML methods usually employ the same features for all classes. However, we find this setting is unreasonable in AU recognition, as the occurrence of different AUs produce changes of skin surface displacement or face appearance in different face regions. If using the shared features for all AUs, much noise will be involved due to the occurrence of other AUs. Consequently, the changes of the specific AUs cannot be clearly highlighted, leading to the performance degradation. Instead, we propose to extract the most discriminative features for each AU individually, which are learned by the supervised learning method. The learned features are further embedded into the instance-level label smoothness term of our model, which also includes the label consistency and the class-level label smoothness. Both a global solution using st-cut and an approximated solution using conjugate gradient (CG) descent are provided. Experiments on both posed and spontaneous facial expression databases demonstrate the superiority of the proposed method in comparison with several state-of-the-art works.

    Full Text Available In this article, I examine lesbian, gay, bisexual, trans, queer/questioning, intersex, and asexual (LGBTQIA Tumblr bloggers’ bio boxes and “About Me” pages to show the ways gender and sexual orientation identities are constructed through community-regulated and community-generated labeling practices. Tumblr encourages counter-cultures (and labeling practices to not only form but also to thrive due to its distinctive affordances including tagging and blog formatting. This article examines not only how these affordances shape usage and, subsequently, identity construction on Tumblr but also the ways in which Tumblr bloggers have embraced affordances to create community-accepted conventions of identity construction. Additionally, building upon online identity scholarship by Bargh, McKenna, and Fitzsimons and Tiidenberg, this article discusses true self and nonbinary gender and sexual orientation labeling as forms of identity construction that allows LGBTQIA identifying individuals a method for nuanced descriptions of feelings and desires. However, far from perfect, these labeling practices are also grounded in hegemonic female/male, feminine/masculine binary discourse. In a Foucauldian sense, bloggers construct discourse within existing power structures that ignore or erase LGBTQIA as sexual “abnormalities.” Although it is nearly impossible to fully break away from the dominant discourse, these labeling practices can be a useful starting point for conversations about genders and sexualities that lie outside of the hegemonic binary.

  13. European consumers’ interest toward nutritional information on wine labeling: A cross-country analysis*

    2015-01-01

    Full Text Available This paper explores, through an empirical analysis European consumers’ interest toward nutritional information on wine labels, examining interest, knowledge and understanding of these information. In this regard, results from direct survey with a cross-country sample of 500 wine consumers (i.e. respondents drinking at least once a month living in Italy, France and Spain are presented and discussed. Preliminary results reveal that consumers are quite confused about the nutritional aspects of wine and tend to be interested in receiving nutritional information on wine labels. However, the interest expressed towards this kind of information differ from country to country and is influenced by other socio-demographic variables. Findings from current research should be valuable to contribute to the debate on updating international and national standards on wine labelling concerning nutrition. At the same time, the research provides a number of useful indications for policy makers in defining future development of wine nutritional labelling programs and in implementing strategies focused in enhancing efficacy and readability of labels.

    The studies reported here examined differences in user behaviour when presented with a low-fidelity paper prototype compared to fully operational product, and evaluated the effectiveness of different types of enhanced labelling of controls. In the first study with a paper prototype, 30 users of high-pressure washers were asked to choose the settings of the temperature control for different cleaning objects, comparing standard with information-enriched control labelling. In the second study, 34 users operated a real high-pressure washer with different forms of control labelling. The results of both studies provided evidence for some benefits of an information-enriched control labelling over traditional temperature-centred controls labelling. Furthermore, a comparative analysis of the data of the two studies suggested that low-fidelity paper prototypes may have to be used with caution. Therefore, designers need to be aware that the behavioural effects induced by different design modifications may be overestimated when using paper prototypes. The implications of the findings are discussed within the framework of an enlarged concept of fidelity.

    Multicenter longitudinal neuroimaging has great potential to provide efficient and consistent biomarkers for research of neurodegenerative diseases and aging. In rare disease studies it is of primary importance to have a reliable tool that performs consistently for data from many different collection sites to increase study power. A multi-atlas labeling algorithm is a powerful brain image segmentation approach that is becoming increasingly popular in image processing. The present study examined the performance of multi-atlas labeling tools for subcortical identification using two types of in-vivo image database: Traveling Human Phantom (THP) and PREDICT-HD. We compared the accuracy (Dice Similarity Coefficient; DSC and intraclass correlation; ICC), multicenter reliability (Coefficient of Variance; CV), and longitudinal reliability (volume trajectory smoothness and Akaike Information Criterion; AIC) of three automated segmentation approaches: two multi-atlas labeling tools, MABMIS and MALF, and a machine-learning-based tool, BRAINSCut. In general, MALF showed the best performance (higher DSC, ICC, lower CV, AIC, and smoother trajectory) with a couple of exceptions. First, the results of accumben, where BRAINSCut showed higher reliability, were still premature to discuss their reliability levels since their validity is still in doubt (DSC atlas labeling methods. While multi-atlas labeling methods are likely to help improve overall segmentation quality, caution has to be taken when one chooses an approach, as our results suggest that segmentation outcome can vary depending on research interest.

  16. Sensing site-specific structural characteristics and chirality using vibrational circular dichroism of isotope labeled peptides.

    2017-10-04

    Isotope labeling has a long history in chemistry as a tool for probing structure, offering enhanced sensitivity, or enabling site selection with a wide range of spectroscopic tools. Chirality sensitive methods such as electronic circular dichroism are global structural tools and have intrinsically low resolution. Consequently, they are generally insensitive to modifications to enhance site selectivity. The use of isotope labeling to modify vibrational spectra with unique resolvable frequency shifts can provide useful site-specific sensitivity, and these methods have been recently more widely expanded in biopolymer studies. While the spectral shifts resulting from changes in isotopic mass can provide resolution of modes from specific parts of the molecule and can allow detection of local change in structure with perturbation, these shifts alone do not directly indicate structure or chirality. With vibrational circular dichroism (VCD), the shifted bands and their resultant sign patterns can be used to indicate local conformations in labeled biopolymers, particularly if multiple labels are used and if their coupling is theoretically modeled. This mini-review discusses selected examples of the use of labeling specific amides in peptides to develop local structural insight with VCD spectra. © 2017 Wiley Periodicals, Inc.

    Full Text Available Context. MRI of the spinal cord provides a variety of biomarkers sensitive to white matter integrity and neuronal function. Current processing methods are based on manual labeling of vertebral levels, which is time consuming and prone to user bias. Although several methods for automatic labeling have been published; they are not robust towards image contrast or towards susceptibility-related artifacts. Methods. Intervertebral disks are detected from the 3D analysis of the intensity profile along the spine. The robustness of the disk detection is improved by using a template of vertebral distance, which was generated from a training dataset. The developed method has been validated using T1- and T2-weighted contrasts in ten healthy subjects and one patient with spinal cord injury. Results. Accuracy of vertebral labeling was 100%. Mean absolute error was 2.1 ± 1.7 mm for T2-weighted images and 2.3 ± 1.6 mm for T1-weighted images. The vertebrae of the spinal cord injured patient were correctly labeled, despite the presence of artifacts caused by metallic implants. Discussion. We proposed a template-based method for robust labeling of vertebral levels along the whole spinal cord for T1- and T2-weighted contrasts. The method is freely available as part of the spinal cord toolbox.

    Over recent years, click reactions have become recognized as valuable and flexible tools to label biomacromolecules such as proteins, nucleic acids, and glycans. Some of the developed strategies can be performed not only in aqueous solution but also in the presence of cellular components, as well as on (or even in) living cells. These labeling strategies require the initial, specific modification of the target molecule with a small, reactive moiety. In the second step, a click reaction is used to covalently couple a reporter molecule to the biomolecule. Depending on the type of reporter, labeling by the click reaction can be used in many different applications, ranging from isolation to functional studies of biomacromolecules. In this minireview, we focus on labeling strategies for RNA that rely on the click reaction. We first highlight click reactions that have been used successfully to label modified RNA, and then describe different strategies to introduce the required reactive groups into target RNA. The benefits and potential limitations of the strategies are critically discussed with regard to possible future developments. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Directory of Open Access Journals (Sweden)

    Allen Krantz

    2014-03-01

    Full Text Available The first example of a kinetic labeling library designed to enable the discovery of affinity labels is presented. Each library component (1 consists of a variable peptidyl component linked to a biotinyl moiety by a 4-mercaptobenzoyl linker in thioester format. We demonstrate that an affinity label can be uncovered by measuring reaction rates between library pools and the protein target, human serum albumin (HSA and identifying significant outliers. By choosing peptide functionality compatible with a potentially reactive thioester labeling entity, libraries can be screened in pools. It is noteworthy that a limited subset of amino acids (R, S, E, F, Y, l, M, W, and Q that compose the affinity moiety is sufficient to produce rate variances that guide the discovery process. After two rounds of deconvolution, J-FLYEE-NH2 (7-E emerges as a bona fide affinity label of HSA. Unlike known affinity labels, the affinity moiety is not retained in the protein product, but is extruded upon acylation of the protein. This feature affords a method of introducing various payloads, without extraneous elements, onto protein frameworks.

    OBJECTIVES: Acceleration selective arterial spin labeling (AccASL) is a spatially non-selective labeling technique, used in traditional ASL methods, which labels spins based on their flow acceleration rather than spatial localization. The exact origin of the AccASL signal within the vasculature...... of the control and label conditions in both the acceleration and velocity selective module. The cut-off acceleration (0.59 m/s(2)) or velocity (2 cm/s) was kept constant in one module, while it was varied over a large range in the other module. With the right subtractions this resulted in AccASL, VS......-ASL, combined AccASL and VS-ASL signal, and signal from one module with crushing from the other. RESULTS: The label created with AccASL has an overlap of approximately 50% in the vascular region with VS-ASL, but also originates from smaller vessels closer to the capillaries. CONCLUSION: AccASL is able to label...

    Injuries related to toys continue to cause significant childhood morbidity and mortality, despite considerable government regulation of the toy industry. Recent controversy related to toys that contain strong magnets demonstrate the dangers they pose to children. The pediatric community is often unaware of how toys receive their developmental and safety labeling and the degree to which age-labeling on toys can be discretionary. Toy labeling has 2 basic manifestations. The first, safety labeling for hazards like small parts, balloons, or small balls that may present a choking risk, is mandatory. The second, "developmental" age-labeling, describes the age of the children for which the toy is intended, and sometimes has discretionary components. This article provides a review of the regulations governing toy age-safety standards and how they are reflected on toy packaging to help pediatric practitioners apply safety advice across settings and patient characteristics. We review the existing age-labeling regulations and processes and discuss the major areas where children remain vulnerable despite labeling. Finally, we list some recommendations for counseling parents about toy safety.

    This review aims to give to the reader some new light on cyclodextrin (CD)-based theranostic agents in order to complete our recently published review dedicated to CD-particles conjugates in drug delivery systems (Zafar et al., 2014). CDs are biocompatible sugar-based macrocycles used in a wide range of biomedical applications. Here, we mainly focus on fundamental theranostic approaches combining the use of cyclodextrin molecules and colloidal particles as theranostic agents. The system's key features are discussed and a few recent pertinent applications are presented. CDs are used in order to enhance theranostic properties by providing apolar cavities for the encapsulation of hydrophobic moieties. Thus, CD molecules are used to enhance the loading capacity of particles by hosting active molecules. The relevance of CDs in enhancing the labeling properties of particles and the preparation of controlled drug release particles is also highlighted.

    Full Text Available Background: Inadequacies of drug labeling have been frequently reported among Malaysian healthcare institutes, in which the Hospital Information System (HIS is used. Objective: To identify potential areas to improve the existing labels used for pediatric liquid medications. Methods: This study was qualitative in nature, whereby focus group discussions (FGDs, face-to-face interviews (FTFIs, and onsite observation were used for data collection. Pharmacists stationed at three units (outpatient, inpatient and clinical pharmacy of a tertiary hospital were targeted. Both FGDs and FTFIs were facilitated using a semi-structured interview guide, video-recorded and transcribed verbatim. All transcripts were thematically analyzed using content analysis approach. Results: Thirteen pharmacists participated in FGDs, while five were approached for FTFIs. Data analysis resulted in four major themes: format of labels, presentation of medication instructions, insufficiency of information, and the need for external aids and education. Participants unanimously agreed on the need for enlarging font sizes of key information. Suggestions were made to use more specific instructions for administration times and pictograms to illustrate important directions. The absence of information about storage, stability and handling of liquid medications was also highlighted. While discussion mainly focused on improving drug labeling, participants consistently stressed the need for an instruction sheet and pharmacist-based, one-to-one education regarding medication instructions. Conclusion: This study provides important insights into critical shortcomings in current labeling practice, underlying the need for developing a new label that incorporates a new format, additional information and pictograms for pediatric liquid medications.

    As many as 98,000 people die every year from preventable medical errors. Among pharmacists, the most common error reported is the selection of the wrong drug. Merck met with the U.S. Food and Drug Administration (FDA) to discuss the optimization of the U.S. label for solid oral dosage forms of Merck medications. These discussions led to the development of revised label designs for six products that were then evaluated using failure modes and effects analysis and an expert review by human factors specialists. There were no errors among 425 filled prescriptions in the validation test of the final label. Key changes to the original labels include the use of a non-branded logo, high-contrast color bands for dosage strength, and an enhanced three-dimensional tablet image. The redesigned labels were approved by the US FDA in June 2011. The redesigned label should improve the accurate selection of medications from pharmacy shelves.

    1990-05-01

    A simple and generally applicable method for labeling antibodies with technetium-99m ({sup 99m}Tc) is described. Following reduction of intrinsic disulphide bonds, the antibody is labeled with {sup 99m}Tc in the presence of a weak competing ligand methylene diphosphonate. High labeling efficiencies (greater than 97%), in a final labeling step taking only a few minutes, can be routinely obtained with high in-vitro stability over 24 hr. No effect upon antibody reactivity is seen.

    Proposed is a novel optical code(OC) label switching scheme in which an optical label is constructed by multiple parallel optical codes. The performances of splitting loss and BER are simulated and analyzed. Simulation results show that the proposed label can be correctly recognized to perform packet switching. Compared with reported schemes using one OC as a label, the splitting loss in our proposal is lowered.

    This research was performed with the aim of developing polymeric radioisotope or drug carriers for obtaining efficient diagnostic therapeutic efficacy. As polymers, polyethylene oxides, polylactides, polycaprolactone were chosen to prepare the devices including micelle system, microemulsion, nanospheres. In addition, anticancer drug loaded polylactide microparticulates were fabricated as a regional chemotherapeutics for the treatment of cancer. Technetium or radioactive iodine was labeled to the polymeric carriers via ligands such as DTPA and HPP, respectively. Labeling efficiency was above 90% and stable enough up to 24 hours. Moreover, injected polymer carriers demonstrated higher blood maintenance and bone uptake than Tin colloid, a control. These results suggested that radioisotope carrying polymeric particulate are promising tools for diagnosing blood vessels or bones. Besides, anticancer drug loaded particulates demonstrated appropriate maintenance of therapeutic concentration and localization. Therefore it was proposed that this therapeutic system may be potential as a cancer therapy modality. 20 refs., 24 figs.,5 tabs. (Author)

  15. Supervised Sequence Labelling with Recurrent Neural Networks

    CERN Document Server

    Graves, Alex

    2012-01-01

    Supervised sequence labelling is a vital area of machine learning, encompassing tasks such as speech, handwriting and gesture recognition, protein secondary structure prediction and part-of-speech tagging. Recurrent neural networks are powerful sequence learning tools—robust to input noise and distortion, able to exploit long-range contextual information—that would seem ideally suited to such problems. However their role in large-scale sequence labelling systems has so far been auxiliary.    The goal of this book is a complete framework for classifying and transcribing sequential data with recurrent neural networks only. Three main innovations are introduced in order to realise this goal. Firstly, the connectionist temporal classification output layer allows the framework to be trained with unsegmented target sequences, such as phoneme-level speech transcriptions; this is in contrast to previous connectionist approaches, which were dependent on error-prone prior segmentation. Secondly, multidimensional...

  16. Matching isotopic distributions from metabolically labeled samples.

    2008-07-01

    In recent years stable isotopic labeling has become a standard approach for quantitative proteomic analyses. Among the many available isotopic labeling strategies, metabolic labeling is attractive for the excellent internal control it provides. However, analysis of data from metabolic labeling experiments can be complicated because the spacing between labeled and unlabeled forms of each peptide depends on its sequence, and is thus variable from analyte to analyte. As a result, one generally needs to know the sequence of a peptide to identify its matching isotopic distributions in an automated fashion. In some experimental situations it would be necessary or desirable to match pairs of labeled and unlabeled peaks from peptides of unknown sequence. This article addresses this largely overlooked problem in the analysis of quantitative mass spectrometry data by presenting an algorithm that not only identifies isotopic distributions within a mass spectrum, but also annotates matches between natural abundance light isotopic distributions and their metabolically labeled counterparts. This algorithm is designed in two stages: first we annotate the isotopic peaks using a modified version of the IDM algorithm described last year; then we use a probabilistic classifier that is supplemented by dynamic programming to find the metabolically labeled matched isotopic pairs. Such a method is needed for high-throughput quantitative proteomic metabolomic experiments measured via mass spectrometry. The primary result of this article is that the dynamic programming approach performs well given perfect isotopic distribution annotations. Our algorithm achieves a true positive rate of 99% and a false positive rate of 1% using perfect isotopic distribution annotations. When the isotopic distributions are annotated given 'expert' selected peaks, the same algorithm gets a true positive rate of 77% and a false positive rate of 1%. Finally, when annotating using machine selected peaks, which

  17. Cross relaxation in nitroxide spin labels

    Cross relaxation, and mI -dependence of the intrinsic electron spin-lattice relaxation rate We , are incorporated explicitly into the rate equations for the electron-spin population differences that govern the saturation behaviour of 14N- and 15N-nitroxide spin labels. Both prove important in spin-label EPR and ELDOR, particularly for saturation recovery studies. Neither for saturation recovery, nor for CW-saturation EPR and CW-ELDOR, can cross relaxation be described simply by increasing the value of We , the intrinsic spin-lattice relaxation rate. Independence of the saturation recovery rates from the hyperfine line pumped or observed follows directly from solution of the rate equations including cross relaxation, even when the intrinsic spin-lattice relaxation rate We is mI -dependent.

    Carreras, X; Marquez, L; Surdeanu, M; 10.1613/jair.2088

    2011-01-01

    This paper introduces and analyzes a battery of inference models for the problem of semantic role labeling: one based on constraint satisfaction, and several strategies that model the inference as a meta-learning problem using discriminative classifiers. These classifiers are developed with a rich set of novel features that encode proposition and sentence-level information. To our knowledge, this is the first work that: (a) performs a thorough analysis of learning-based inference models for semantic role labeling, and (b) compares several inference strategies in this context. We evaluate the proposed inference strategies in the framework of the CoNLL-2005 shared task using only automatically-generated syntactic information. The extensive experimental evaluation and analysis indicates that all the proposed inference strategies are successful -they all outperform the current best results reported in the CoNLL-2005 evaluation exercise- but each of the proposed approaches has its advantages and disadvantages.

    Here we report a nanoparticle label based on apoferritin nanovehicle loaded internally with markers for sensitive electrochemical DNA detection. The central cavity structure, the dissociation and reconstitute properties at different pHs of apoferritin provide a facile method to load and release markers. Hexacynoferrate(III) was used as model marker to load into the cavity of apoferritin protein cage. The loaded nanoparticle surface was functionalized with amino-modified DNA probe. Electrochemical DNA hybridization assay based on the hexacynoferrate loaded apoferritin nanovehicle could detect 23 atmol DNA targets in 50 ul sample solution. The concept could be readily extended to load other redox and fluorescence markers for bioassay applications. The new nanoparticle labels hold great promise for multi-target detection (in connection to nanoparticles loaded with different markers) and for enhancing the sensitivity of other bioassays.
