    In 2015, a century after Albert Einstein published his theory of general relativity, the Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves from binary black holes fully consistent with this theory. Our goal for VIGOR (Virtual-reality Interaction with Gravitational waves to Observe Relativity) is to communicate this revolutionary discovery to the public by visualizing the gravitational waves emitted by binary black holes. VIGOR has been developed using the Unity game engine and VR headsets (Oculus Rift DK2 and Samsung Gear VR). Wearing a VR headset, VIGOR users control an avatar to "fly" around binary black holes, experiment on the black holes by manipulating their total mass, mass ratio, and orbital separation, and witness how gravitational waves emitted by the black holes stretch and squeeze the avatar. We evaluated our prototype of VIGOR with high school students in 2016 and are further improving VIGOR based on our findings.

    Finding patterns in graphs has become a vital challenge in many domains from biological systems, network security, to finance (e.g., finding money laundering rings of bankers and business owners). While there is significant interest in graph databases and querying techniques, less research has focused on helping analysts make sense of underlying patterns within a group of subgraph results. Visualizing graph query results is challenging, requiring effective summarization of a large number of subgraphs, each having potentially shared node-values, rich node features, and flexible structure across queries. We present VIGOR, a novel interactive visual analytics system, for exploring and making sense of query results. VIGOR uses multiple coordinated views, leveraging different data representations and organizations to streamline analysts sensemaking process. VIGOR contributes: (1) an exemplar-based interaction technique, where an analyst starts with a specific result and relaxes constraints to find other similar results or starts with only the structure (i.e., without node value constraints), and adds constraints to narrow in on specific results; and (2) a novel feature-aware subgraph result summarization. Through a collaboration with Symantec, we demonstrate how VIGOR helps tackle real-world problems through the discovery of security blindspots in a cybersecurity dataset with over 11,000 incidents. We also evaluate VIGOR with a within-subjects study, demonstrating VIGOR's ease of use over a leading graph database management system, and its ability to help analysts understand their results at higher speed and make fewer errors.

    Full Text Available A feature of the management of natural resources in the coastal zone is that it involves multiple stakeholders. It has been suggested that the effectiveness of coastal management relies on the cooperation of this multitude of stakeholders in decision-making. This study reports on the findings of an investigation into the modes of interaction used by coastal researchers to communicate with stakeholders. A qualitative research methodology was used through both telephone and in-depth face-toface interviews to elucidate the mechanisms of interaction and, in turn, produce a typology of interaction modes. It was found that there were five main modes of interaction: Limited; Mediator Achieved; Key Stakeholder; Full Interaction and Mixed and that the discipline area in which the researcher worked did not dictate their preferred mode of interaction. It was concluded that although there are a number of limitations to effective participation, these interactions have significant implications for meaningful participation in the management of coastal resources.

    New policies on flood management called Multi-Level Safety (MLS), demand for an integral and collaborative approach. The goal of MLS is to minimize flood risks by a coherent package of protection measures, crisis management and flood resilience measures. To achieve this, various stakeholders, such as water boards, municipalities and provinces, have to collaborate in composing these measures. Besides the many advances this integral and collaborative approach gives, the decision-making environment becomes also more complex. Participants have to consider more criteria than they used to do and have to take a wide network of participants into account, all with specific perspectives, cultures and preferences. In response, sophisticated models are developed to support decision-makers in grasping this complexity. These models provide predictions of flood events and offer the opportunity to test the effectiveness of various measures under different criteria. Recent model advances in computation speed and model flexibility allow stakeholders to directly interact with a hydrological hydraulic model during meetings. Besides a better understanding of the decision content, these interactive models are supposed to support the incorporation of stakeholder knowledge in modelling and to support mutual understanding of different perspectives of stakeholders To explore the support of interactive modelling in integral and collaborate policies, such as MLS, we tested a prototype of an interactive flood model (3Di) with respect to a conventional model (Sobek) in two cases. The two cases included the designing of flood protection measures in Amsterdam and a flood event exercise in Delft. These case studies yielded two main results. First, we observed that in the exploration phase of a decision-making process, stakeholders participated actively in interactive modelling sessions. This increased the technical understanding of complex problems and the insight in the effectiveness of various

    In the Spring of 2013, the Idaho National Laboratory (INL) began discussions with industry stakeholders on how to upgrade our safety analysis capabilities. The focus of these improvements would primarily be on advanced safety analysis capabilities that could help the nuclear industry analyze, understand, and better predict complex safety problems. The current environment in the DOE complex is such that recent successes in high performance computer modeling and simulation could lead the nuclear industry to benefit from these advances, as long as an effort to translate these advances into realistic applications is made. Upgrading the nuclear industry modeling analysis capabilities is a significant effort that would require participation and coordination from all industry segments: research, engineering, vendors, and operations. We focus here on interactions with industry stakeholders to develop sound advanced safety analysis applications propositions that could have a positive impact on industry long term operation, hence advancing the state of nuclear safety.

    The genetic basis of seed germination and seedling vigor is largely unknown in Brassica species. We performed a study to evaluate the genetic basis of these important traits in a B. rapa doubled haploid population from a cross of a yellow-seeded oil-type yellow sarson and a black-seeded vegetable-type pak choi. We identified 26 QTL regions across all 10 linkage groups for traits related to seed weight, seed germination and seedling vigor under non-stress and salt stress conditions illustrating the polygenic nature of these traits. QTLs for multiple traits co-localized and we identified eight hotspots for quantitative trait loci (QTL) of seed weight, seed germination, and root and shoot lengths. A QTL hotspot for seed germination on A02 mapped at the B. rapa Flowering Locus C (BrFLC2). Another hotspot on A05 with salt stress specific QTLs co-located with the B. rapa Fatty acid desaturase 2 (BrFAD2) locus. Epistatic interactions were observed between QTL hotspots for seed germination on A02 and A10 and with a salt tolerance QTL on A05. These results contribute to the understanding of the genetics of seed quality and seeding vigor in B. rapa and can offer tools for Brassica breeding. PMID:26648948

    2015-07-01

    Full Text Available In order to directly involve stakeholders in socio-technical system design, we argue for streamlining executable process specifications with business process modeling. Due to current agility requirements of organizations, socio-technical system development is considered one of the key activities of members of the organizations. Dynamic process adaptation enable handling the volatility of business operation and IT infrastructure. Subject-oriented process representations are key enablers to dynamic adaptation due to their capability for stakeholders to create directly executable models. In this way stakeholder can be involved in change management pro-actively. Subject-oriented models (i represent all relevant features required for system control and decision making, and (ii are executable on demand. This effectiveness enables organizational change in a creative and efficient way, while establishing innovative design and change management tools. Subject-oriented Business Process Management capabilities are reflected in this realm revealing benefits and potential for further research.

    The International Radiation Protection Association's guiding principles for stakeholder engagement focus on fostering, facilitating, and enabling interaction among stakeholders that is inclusive and fosters competent decision making. Implicit in these standards is a call to cultivate knowledge and competence in designing communication for stakeholder engagement among radiation protection professionals. Communication as design is an approach to risk communication in science and policy that differs from, yet complements, the more well-known communication practices of informing and persuading. Design focuses on the recurring practical problem faced by professionals in making communication possible among stakeholders where it has otherwise been difficult, impossible, or even unimagined. The knowledge and competence associated with design involves principles for crafting interactivity across a variety of mediated and non-mediated encounters among stakeholders. Risk communication can be improved by cultivating expertise in scalable communication design that embraces the demands of involvement without abandoning the need for competence in science and policy communication.

    Interspecific hybridization can be considered an accelerator of evolution, otherwise a slow process, solely dependent on mutation and recombination. Upon interspecific hybridization, several novel interactions between nuclear and cytoplasmic genomes emerge which provide additional sources of diversity. The magnitude and essence of intergenomic interactions between nuclear and cytoplasmic genomes remain unknown due to the direction of many crosses. This study was conducted to address the role of nuclear-cytoplasmic interactions as a source of variation upon hybridization. Wheat (Triticum aestivum) alloplasmic lines carrying the cytoplasm of Aegilops mutica along with an integrated approach utilizing comparative quantitative trait locus (QTL) and epigenome analysis were used to dissect this interaction. The results indicate that cytoplasmic genomes can modify the magnitude of QTL controlling certain physiological traits such as dry matter weight. Furthermore, methylation profiling analysis detected eight polymorphic regions affected by the cytoplasm type. In general, these results indicate that novel nuclear-cytoplasmic interactions can potentially trigger an epigenetic modification cascade in nuclear genes which eventually change the genetic network controlling physiological traits. These modified genetic networks can serve as new sources of variation to accelerate the evolutionary process. Furthermore, this variation can synthetically be produced by breeders in their programs to develop epigenomic-segregating lines.

    Full Text Available Firm survival in emerging economies is often related to having access to valuable resources that are in stakeholders‟ hands. However, the literature on strategy in emerging economies provides scant information on the efficiency of acquiring stakeholder resources and its effect on firm performance. We investigated the stakeholder interaction effects on performance of domestic firms competing in an emerging market (Wright, Filatotchev, Hoskisson, & Peng, 2005 from a contractual perspective (Williamson, 1985. We argue that interacting stakeholders in a contractual set yield synergistic governance structures that allow firms more efficient access to external resources. Using a sample of 267 firms in Brazil (secondary data, we explored different patterns in stakeholder contracting with community, government, top management, and employees. A three-stage analysis process was devised: cluster analysis, general linear model estimation and verification tests. Results suggest that stakeholder interaction has a positive impact on firm performance. The conjoint effect of government and community contracts was found to yield superior firm performance as they provide a basic structure for contracting with other interacting stakeholders.

  17. Using interactive 3D visualisation to educate stakeholders in urban sustainability

    2010-05-01

    Sustainable decision making in urban design is a complex and non-linear process, which requires the education and interaction of wide variety of stakeholders. A number of sustainable decision support tools have been developed but previous research by the authors has demonstrated that a major barrier to the implementation of tools is the complexity of the environment in which decision are made. In particular, engagement with the general public throughout the decision making process presents challenges in communicating the complex and interdependent facets of sustainability in decisions and also in providing an understanding to stakeholders of the short and long term implications of alternative courses of action. S-City VT, a prototype simulation and visualisation tool, demonstrates the underlying concepts that allow a wider range of stakeholders to understand, interact with and influence decisions regarding sustainability of urban design. Using the Dundee Waterfront Development Project as a case study, S-City VT takes the unique approach of combining computer game technology with computer modelling to present the stakeholder with an interactive virtual development. The virtual development is completely interactive allowing users to change the underlying models as well as the external appearance and location of buildings and other structures within the development. This provides a more interactive experience by allowing the user a one to one relationship with the environment they are interacting with, as opposed to existing off the shelf solutions, such as CAD or BIM, that lack in real time interactivity. S-City VT utilises existing games technology research to allow the rendering of virtual environment on consumer hardware opening up its use to a wider range of participants and venues by not relying on specialist hardware. The visualisation tool employs a number of different methods to display the multivariate sustainability data to the stakeholders. These methods

    Participatory approaches involve stakeholder interaction but environmental agency employees engaged in participatory undertakings often lack training for interaction tasks. This study explored how district officers at the Soil Conservation Service of Iceland (SCSI) experienced and dealt with stakeholder interaction in participatory land restoration. We made semi-structured interviews with all district officers with at least 1-year experience; seven in total. A thematic content analysis revealed five challenges facing the officers in their interaction activities and seven strategies that they used to deal with these challenges. The core challenge was to establish and maintain contacts with farmers and other stakeholders as it enabled the SCSI to support and influence their land restoration practices. Other challenges were to: accomplish SCSI's objectives; represent the SCSI and the government; have adequate skills, knowledge, and background; and deal with one's own emotions. Four of the strategies seemed to promote collaboration: create win-win scenarios; "go local"; direct and positive communication; and motivation and knowledge sharing. The other strategies: supportive district officer team; self-reliance and personal background; and self-control supported the officers in their interaction tasks. Factors undermining their collaboration efforts included insufficient time and other resources, an unsupportive organizational culture and a legal duty to assess the condition of vegetation cover on farmland. Increased resource allocation to the SCSI's local operations, more attention to emotional issues, and efforts to develop a more flexible and learning organizational culture that supports collaboration could counteract these factors.

  19. Interactive Cumulative Burden Assessment: Engaging Stakeholders in an Adaptive, Participatory and Transdisciplinary Approach.

    Cumulative burden assessment (CuBA) has the potential to inform planning and decision-making on health disparities related to multiple environmental burdens. However, scholars have raised concerns about the social complexity to be dealt with while conducting CuBA, suggesting that it should be addressed in an adaptive, participatory and transdisciplinary (APT) approach. APT calls for deliberation among stakeholders by engaging them in a process of social learning and knowledge co-production. We propose an interactive stakeholder-based approach that facilitates a science-based stakeholder dialogue as an interface for combining different knowledge domains and engendering social learning in CuBA processes. Our approach allows participants to interact with each other using a flexible and auditable CuBA model implemented within a shared workspace. In two workshops we explored the usefulness and practicality of the approach. Results show that stakeholders were enabled to deliberate on cumulative burdens collaboratively, to learn about the technical uncertainties and social challenges associated with CuBA, and to co-produce knowledge in a realm of both technical and societal challenges. The paper identifies potential benefits relevant for responding to social complexity in the CuBA and further recommends exploration of how our approach can enable or constraint social learning and knowledge co-production in CuBA processes under various institutional, social and political contexts.

    Timely injection of knowledge when interacting with stakeholders and policy makers. J.Bouma Em. Prof. Soil Science, Wageningen University, the Netherlands During the last decade, the spectacular development of Information and Communication Technology (ICT) has strongly increased the accessible amount of data and information for stakeholders and policy makers and the science community is struggling to adjust to these developments. In the Netherlands not only industry has now a major impact on the research agenda but this is now to be extended to citizens at large. Rather than complain about an apparent "gap" between science and society and wrestle with the challenge to bridge it in a rather reactive manner, the science community would be well advised to initiate a proactive approach, showing that knowledge implies a deep understanding of issues and processes that does not necessarily follow from having data and information. The "gap" certainly applies to soil research in the context of sustainable development where many often well informed stakeholders are involved with widely different opinions, norms and values. Changes are suggested in the manner in which we frame our work: (i) longer involvement with projects from initiation to implementation in practice; (ii) active role of "knowledge brokers" who inject the right type of knowledge during the entire project run in a joint-learning mode, and (iii) not proposing new research from a science perspective but demonstrating a clear need because existing knowledge is inadequate. Yet more conceptual discussions about e.g. inter- and transdisciplinarity, worrysome soil degradation and lack of professional recognition are less meaningful than specific case studies demonstrating the crucial role of soil science when analysing land-based environmental problems. New narratives are needed instead of statistics, openness to learn from best practices and pilot projects as a necessary next step beyond awareness raising. Soil

    Full Text Available Identifying intra-locus interactions underlying heterotic variation among whole-genome hybrids is a key to understanding mechanisms of heterosis and exploiting it for crop and livestock improvement. In this study, we present the development and first use of the heterotic trait locus (HTL mapping approach to associate specific intra-locus interactions with an overdominant heterotic mode of inheritance in a diallel population using Sorghum bicolor as the model. This method combines the advantages of ample genetic diversity and the possibility of studying non-additive inheritance. Furthermore, this design enables dissecting the latter to identify specific intra-locus interactions. We identified three HTLs (3.5% of loci tested with synergistic intra-locus effects on overdominant grain yield heterosis in 2 years of field trials. These loci account for 19.0% of the heterotic variation, including a significant interaction found between two of them. Moreover, analysis of one of these loci (hDPW4.1 in a consecutive F2 population confirmed a significant 21% increase in grain yield of heterozygous vs. homozygous plants in this locus. Notably, two of the three HTLs for grain yield are in synteny with previously reported overdominant quantitative trait loci for grain yield in maize. A mechanism for the reproductive heterosis found in this study is suggested, in which grain yield increase is achieved by releasing the compensatory tradeoffs between biomass and reproductive output, and between seed number and weight. These results highlight the power of analyzing a diverse set of inbreds and their hybrids for unraveling hitherto unknown allelic interactions mediating heterosis.

    In the paradigm shift in flood management from traditional to more integrated approach the key to initialising this transition stage is capacity building of stakeholders. It supports the effective participation of stakeholders within their role by giving the individuals/professionals and institutions required knowledge and skills. Such a process of empowering targeted stakeholder groups should be based on the interactive learning rather than mere delivering of flood related information. It can be achieved by initiating the learning process and developing life-long learning programs in form of blended learning that combines both, supervised online and face-to-face approaches. The learning concept based on the didactic principle of Kolb/Fry, has been used as a basis for development of the Interactive Learning Program (ILP) presented in this paper. Kolb/Fry define learning as a cyclic process dividing it into four steps: concrete experience, reflection & observation, forming abstract concepts, testing of acquainted knowledge in new situations. As the knowledge to understand the complexity of IFM is extensive and required level usually cannot be achieved within the face-to-face phase, additional autodidactic learning module tailored to the individual skills should be included in the learning program. ILP combines both, the face-to-face sessions following the Kolb?s learning cycle including theoretical and practical aspects and autodidactic phase by means of the e-learning platform based on the web dissemination strategy for IFM- Kalypso Inform (Pasche/Kraus/Manojlovic). According to this strategy, the access to the flood related information is enabled through three different modules Tutorial, Knowledge Base and Virtual Trainer enabling interaction with the system. This ILP is generic and can be tailored to requirements of different stakeholder groups depending on their role and level of integration in IFM. The first results, obtained for both public and private

    2013-10-18

    In recent years, the transition of the power supply chain towards a sustainable system based on 'green' electricity generation out of renewable energy sources (RES-E) has become a main challenge for grid operators and further stakeholders in the power system. To enable the evaluation of new concepts for the integration of RES-E, first the feed-in characteristics of photovoltaic, wind and biomass generators located in a distribution grid area and based on numerous measured feed-in data are studied in this thesis. The achieved insights from the feed-in profiles can be used for the dimensioning of grid assets. Furthermore, the results are useful for the evaluation of congestion management or for the dimensioning of storage assets in distribution grids. The latter aspect is analyzed in detail such that suitable storage characteristics for an introduction in the grid are determined. An economic approach is presented to derive break-even points for storage assets as a substitute to conventional reinforcements. For a case study from a real world low voltage grid with reinforcement needs, these break-even points are determined and the main influencing parameters are evaluated. A further important question in this context concerns the role DSOs (distribution system operators) may play with the operation of decentralized storage assets since several stakeholders may be interested in using the flexibility provided by these assets. This unclear responsibility also applies to the steering of adjustable consumption devices such as electric heat pumps or electric cars. For decentralized storage assets as well as heat pump appliances, optimal operation modes based on the optimization objectives for a DSO and a trader are derived. It is shown based on real world data that choosing a 'copperplate' scenario is not only technically insufficient for a global balance of the consumption and generation. It may even be harmful for the society from a welfare economic

One strategy for coping with theoretical immaturity is to import and adapt theories from other, more mature fields. This study reviews Stakeholder Theory (ST) and investigates its potential in relation...... to e-Government. Originally a management theory, stakeholder theory advocates addressing the concerns of all stakeholders in a firm, as opposed to concentration on the interests of senior managers and stockholders. Apart from the original profit focus, there is no serious conceptual mismatch between...... stakeholder theory and government’s objective of providing policy and services for citizens and organizations – society’s stakeholders. Potential problems with adapting a management theory to a government setting are discussed. The paper further discusses how information technology impacts a stakeholder model...

    Stakeholders plays an important roles to determine the system requirements. Stakeholders are people or organizations that has an interest to the enterprise. Timely and effective consultation of relevant stakeholders is a paramount importance in the requirements engineering process. From the research and analysis of system stakeholder finds that there are four stakeholder groups in IAIS. Stakeholder analysis is being implemented by identifying stakeholder, stakeholder category, and analysis interaction between stakeholders.

    Full Text Available Objective – This paper attempts to understand how the stakeholders in an organization - which strives to achieve goals that are sometimes in conflict - construct and reconstruct (through their interactions their beliefs (values related to organizational competition and habits of action (practices. Design/methodology/approach – A qualitative single case study was conducted at a tax consulting firm in the service sector in Brazil, with ongoing organizational change. The firm seeks to find an even balance between fostering human and social development and financial earnings. Semi-structured and in-depth interviews were conducted with the founder, employees, customers and suppliers, in addition to nonparticipant observation, naturally occurring discussions, and documents. Findings – The analysis of the discursive materials showed that organizational practices reflect values formed over several years through the paradoxical tension between the world views of the founder on how the business world actually is and how it should be. The value of “coherence between what is said and what is done” permeated several reflexivity practices, when decisions were taken and the reasons underpinning them were discussed by management and employees, in pursuit of the goals initially proposed. Practical implications – This research contributes to wider-ranging reflections on the competitive world of organizations dealing with the challenges that face them, extending beyond social responsibility. It also illustrates that reflexivity may be particularly helpful in other forprofit organizations, particularly those focused on social innovation. Originality/value – This study promotes a discussion of change as a continuous process, grounded on a differentiated approach to organizational values, highlighting the emerging characteristics of organizational becoming.

    2016-01-01

    Integrating theory when developing complex quality improvement interventions can help to explain clinical and organizational behavior, inform strategy selection, and understand effects. This paper describes a theory-informed interactive dissemination strategy. Using aggregated quality improvement data, the strategy seeks to engage stakeholders in wide-scale data interpretation and knowledge sharing focused on achieving wide-scale improvement in primary health-care quality. An iterative process involving diverse stakeholders in Australian Aboriginal and Torres Strait Islander health-care delivery uses aggregated audit data collected across key areas of care. Phases of reporting and online feedback are used to identify: (1) priority areas for improvement; (2) health center, system, and staff attributes that may be important in addressing the identified priority evidence-practice gaps; and (3) strategies that could be introduced or strengthened to enable improvement. A developmental evaluation is being used to refine engagement processes and reports as the project progresses. This innovative dissemination approach is being used to encourage wide-scale interpretation and use of service performance data by policy-makers, managers, and other stakeholders, and to document knowledge about how to address barriers to achieving change. Through the developmental evaluation, the project provides opportunities to learn about stakeholders' needs in relation to the way data and findings are described and distributed, and elements of the dissemination strategy and report design that impact on the useability and uptake of findings. The project can contribute to knowledge about how to facilitate interactive wide-scale dissemination and about using data to co-produce knowledge to improve health-care quality.

    2013-03-01

    This study examines the existing norms regarding immunisation within the communities and the ethical notions that govern the actions of different health professionals and their collective synergistic or conflicting effects on the governance of the programme. We used descriptive and analytical qualitative methods as it suited the research question. The data were collected from areas under 16 primary health centres in Kerala and Tamil Nadu identified through a three-step sampling process. This involved in-depth interviews with stakeholders including providers, beneficiaries and other stakeholders, focus group discussions with mothers of under-five children and participant and non-participant observations of vaccination-related activities. Unlike most other ethical analyses that look at the ethics of vaccination policies, the interactions of normative principles and notions are analysed in this article. Moral obligation of parents towards their children, beneficence of healthcare providers and the utilitarian aspirations of the state are the key normative principles involved. Our analysis points to the interplay of both synergy and conflict in ethical notions and moral values in the context of immunisation services. Paternalistic interventions like special immunisation campaigns against polio and Japanese encephalitis are a case in point: they generate conflict at the normative level and create mistrust. Analysis of vaccination policies and programmes needs to go beyond factors that assess monetary benefits or herd immunity. Understanding the interactions of normative notions that shape the social organisation of the providers and the users of vaccination is important in creating a sustainable environment for the programme.

    2013-10-01

    Full Text Available Port cities are historically important breeding places of civilization and wealth, and act as attractive high-quality and sustainable places to live and work. They are core places for sustainable development for the entire spatial system as a result of their dynamism, which has in recent years reinforced their position as magnets in a spatial-economic force field. To understand and exploit this potential, the present study presents an analytical framework that links the opportunities provided by traditional port areas/cities to creative, resilient and sustainable urban development. Using evidence-based research, findings are presented from a case study by employing a stakeholder-based model—with interactive visual support tools as novel analysis methods—in a backcasting and forecasting exercise for sustainable development. The empirical study is carried out in and around the NDSM-area, a former dockyard in Amsterdam, the Netherlands. Various future images were used—in an interactive assessment incorporating classes of important stakeholders—as strategic vehicles to identify important policy challenges, and to evaluate options for converting historical-cultural urban port landscapes into sustainable and creative hotspots, starting by reusing, recovering, and regenerating such areas. This approach helps to identify successful policy strategies, and to bring together different forms of expertise in order to resolve conflicts between the interests (or values of a multiplicity of stakeholders, with a view to stimulating economic vitality in combination with meeting social needs and ensuring the conservation of eco-systems in redesigning old port areas. The results indicate that the interactive policy support tools developed for the case study are fit for purpose, and are instrumental in designing sustainable urban port areas.

    The purpose of this study was to explore the experiences of patients with aphasia, their family members, and physicians related to communication during medical interactions. Face-to-face, semistructured interviews were conducted with 18 participants—6 patients with aphasia, 6 family members involved in patient care, and 6 practicing physicians. A qualitative description approach was used to collect and summarize narratives from participants' perspectives and experiences. Participants were asked about experiences with communication during medical interactions in which the family member accompanied the patient. Interviews were audio- and/or video-recorded, transcribed, and then coded to identify main themes. Patients and family members generally described their communication experiences as positive, yet all participants discussed challenges and frustrations. Three themes emerged: (a) patients and family members work as a team, (b) patients and family members want physicians to "just try" to communicate with the patient, and (c) physicians want to interact with patients but may not know how. Participants discussed the need for successful accommodation, or changing how one communicates, to help facilitate the patients' increased understanding and ability to express themselves. Over- and underaccommodation with communication were commonly reported as problems. Speech-language pathologists have a role to play in helping to improve communication during medical interactions. Implications for current speech-language pathologist practice and future directions of research are discussed.

  17. Stock-scion interactions on growth and rubber yield of Hevea brasiliensis Interação porta-enxerto x enxerto sobre vigor e produção de borracha de Hevea brasiliensis

    2007-06-01

    Full Text Available Rubber tree cultivation [Hevea brasiliensis (Willd. ex Adr. de Juss. Muell.-Arg.] uses mostly the budding propagation method, however the expected stand uniformity due to the use of vegetative propagation is theoretical, since high variation for yield and vigor is caused by rootstock influence. The objective of this study was to assess several combinations between clonal rootstocks and clone scions through diallel analysis, aiming at high productivity and vigor. Data consisted of five years of dry rubber yield and girth at panel opening from an experiment using a split-plot design with four replications, conducted at Pindorama, SP, Brazil, considering six rootstocks (GT 1, IAN 873, PB 235, RRIM 600, RRIM 701 and unselected seedlings and six scions (GT 1, IAN 873, PB 235, PR 107, RRIM 600 and RRIM 701. A 6 ´ 6 partial diallel analysis summing up 36 combinations was undertaken, and general compatibility for each group of materials (rootstocks and scions and specific compatibility among all combinations were estimated. The results have shown that PB 235 and IAN 873 rootstocks provided high yields and general compatibility values (7.9348 and 2.7647, respectively. The use of unselected seedlings as rootstocks is not recommended because they presented very low compatibility values for dry rubber yield. Towards growth vigor, the tested rootstocks have shown similar performance.Na cultura da seringueira [Hevea brasiliensis (Willd. ex Adr. de Juss. Muell.-Arg.], o método de propagação mais usado é a enxertia, mas a uniformidade esperada usando propagação vegetativa é teórica, uma vez que altas variações para produção e vigor são causados pela influência do porta-enxerto. O objetivo do presente trabalho foi avaliar várias combinações entre porta-enxertos clonais e enxertos (clones através de análise dialélica, visando-se alta produção e vigor.

    Carrying out a project as planned is not a guarantee for success. Projects may fail because project management does not take the requirements, wishes and concerns of stakeholders sufficiently into account. Projects can only be successful though contributions from stakeholders. And in the end, it is the stakeholders that evaluate whether they find that the project is a success. To manage stakeholders effectively, you need to know your stakeholders, their behaviours and attitudes towards the project.

    This paper updates and builds on ‘Modelling with Stakeholders’ Voinov and Bousquet, 2010 which demonstrated the importance of, and demand for, stakeholder participation in resource and environmental modelling. This position paper returns to the concepts of that publication and reviews the progress made since 2010. A new development is the wide introduction and acceptance of social media and web applications, which dramatically changes the context and scale of stakeholder interactions and participation. Technology advances make it easier to incorporate information in interactive formats via visualization and games to augment participatory experiences. Citizens as stakeholders are increasingly demanding to be engaged in planning decisions that affect them and their communities, at scales from local to global. How people interact with and access models and data is rapidly evolving. In turn, this requires changes in how models are built, packaged, and disseminated: citizens are less in awe of experts and external authorities, and they are increasingly aware of their own capabilities to provide inputs to planning processes, including models. The continued acceleration of environmental degradation and natural resource depletion accompanies these societal changes, even as there is a growing acceptance of the need to transition to alternative, possibly very different, life styles. Substantive transitions cannot occur without significant changes in human behaviour and perceptions. The important and diverse roles that models can play in guiding human behaviour, and in disseminating and increasing societal knowledge, are a feature of stakeholder processes today.

    Caniato, M; Tudor, T; Vaccari, M

    2015-01-01

    The sustainable management of waste requires a holistic approach involving a range of stakeholders. What can often be difficult is to understand the manner in which different types of stakeholder networks are composed and work, and how best to enhance their effectiveness. Using social network analysis and stakeholder analysis of healthcare waste management stakeholders in the case study region of the Gaza Strip, this study aimed to understand and examine the manner in which the networks functioned. The Ministry of Health was found to be the most important stakeholder, followed by municipalities and solid waste management councils. Some international agencies were also mentioned, with specific roles, while other local institutions had a limited influence. Finally while health-care facilities had a strong interest in waste management, they were generally poorly informed and had limited links to each other. The manner in which the networks operated was complicated and influenced by differences in perception, sharing of information, access to finance and levels of awareness. The lack of a clear legal framework generated various mistakes about roles and responsibilities in the system, and evidently regulation was not an effective driver for improvement. Finally stakeholders had different priorities according to the waste management issues they were involved with, however segregation at the source was identified as a key requirement by most. Areas for improving the effectiveness of the networks are suggested. The analysis utilized an innovative methodology, which involved a large number of stakeholders. Such an approach served to raise interest and awareness at different levels (public authorities, health providers, supporting actors, others), stimulate the discussion about the adoption of specific policies, and identify the effective way forward.

    To examine cross-sectional associations between vigorous physical activity, mental health, perceived stress, and socializing among 4-year college students. A national cross-sectional sample of 4-year colleges in the United States. Ninety-four 4-year colleges in the United States. A total of 14,804 undergraduate students. Self-report vigorous physical activity, perceived stress (measured using the Cohen Perceived Stress Scale), mental health (measured using the SF-36), and socializing (assessed using self-report number of friends and hours spent socializing). Logistic regression models accounting for clustering within schools were estimated to examine the association between vigorous physical activity, mental health, perceived stress, and socializing. Adjusted models included high school vigorous physical activity and sociodemographic characteristics. Students who met vigorous physical activity recommendations were less likely to report poor mental health (adjusted odds ratio [OR]: .79; 95% confidence interval [CI]: .69, .90) and perceived stress (adjusted OR: .75; 95% CI: .67, .83) than students who did not meet recommendations. In addition, socializing partially mediated the relationship between vigorous physical activity, mental health, and perceived stress; however, race and sex did not moderate the relationship. Interventions aiming to improve mental well-being of college students should also consider promoting physical activity. At least some of the positive benefits of physical activity may arise from social interactions.

    There is controversy regarding whether moderately-intense sports can improve physical fitness, which declines throughout adolescence among girls. The objective was to estimate the association between moderate and vigorous sports participation and cardiorespiratory fitness in a racially diverse sample of adolescent girls. Cardiorespiratory fitness was measured using a modified physical work capacity test in 1029 eighth-grade girls participating in the Trial of Activity for Adolescent Girls. Girls reported sports in which they participated in the last year on an organized activity questionnaire. Using general linear mixed models, the study regressed absolute and relative fitness on the number of vigorous and moderate sports in which girls participated, race/ethnicity, age, treatment group, fat mass, fat-free mass, and an interaction between race and fat-free mass. The number of vigorous sports in which girls participated was positively associated with absolute fitness (β = 10.20, P = .04) and relative fitness (β = 0.17, P = .04). Associations were reduced, but not eliminated, after controlling for MET-weighted MVPA. Participation in moderate sports was not associated with either fitness measure. Vigorous sports participation is positively associated with cardiorespiratory fitness. Future longitudinal research should analyze whether promoting vigorous sports at an early age can prevent age-related declines in cardiorespiratory fitness among adolescent girls.

    1A Decade of Diminishing Sunspot Vigor William Livingston1 Matt Penn1 Leif Svalgard2 Sunspots are small dark areas on the solar disk where internal magnetism, 1500 to 3500 Gauss, has been buoyed to the surface. (Spot life times are the order of one day to a couple of weeks or more. They are thought to be dark because convection inhibits the outward transport of energy there). Their "vigor” can be described by spot area, spot brightness intensity, and magnetic field. From 2001 to 2011 we have measured field strength and brightness at the darkest position in umbrae of 1750 spots using the Zeeman splitting of the Fe 1564.8 nm line. Only one observation per spot per day is carried out during our monthly telescope time of 3-4 days average. Over this interval the temporal mean magnetic field has declined about 500 Gauss and mean spot intensity has risen about 20%. We do not understand the physical mechanism behind these changes or the effect, if any, it will have on the Earth environment. 1. wcl@noao.edu mpenn@noao.edu 2. leif@leif.org

However, during the last decades, phenomena such as the financial crisi...... in a globalised and future perspective considering using the RESIST-model against ‘business-as-usual’ based on the butterfly effect of the smallest decision......., the global warming, the disasters of global consumerism in terms of the collapse of the Rana Plaza factory in the fashion industry, are examples of how the stakeholder concept cannot continue to be defined as narrow as corporations usually does. The butterfly effect of globalism has shown to be – yes, global...

  1. Recent approaches for bell pepper seed vigor testing

    Directory of Open Access Journals (Sweden)

    Marcos Altomani Neves Dias

    2014-08-01

    Full Text Available Seed vigor is a major attribute in the determination of whether a seed lot can be commercialized. Different physiological tests are used to assess seed vigor and are generally based on different concepts, which could lead to variable interpretations, particularly when comparing lots presenting different vigor levels. This study was conducted to compare the different approaches used to evaluate bell pepper seed vigor and verify the applicability of the Seed Vigor Imaging System (SVIS for this purpose. The experiment was performed using four seed lots of bell pepper hybrids in two periods, and the evaluations involved germination, seedling emergence, seedling emergence speed index, saturated salt accelerated aging and image analysis. The use of seedling imaging analysis by SVISis a new approach for bell pepper seed vigor evaluation. Both the software and traditional tests provided sufficient information for seed vigor analysis, enabling the segregation of the analyzed seed lots. Thus, the new method fulfills the requirement for an efficient, rapid, cost-effective and standardized method that allows comparisons among laboratories and avoids human influence on the interpretation of the results. SVIS can be considered a feasible option to be included in quality assurance programs of the bell pepper seed industry.

  3. Stakeholder Analysis To Shape the Enterprise

    Science.gov (United States)

    McCaughin, Keith; Derosa, Joseph

    An enterprise is a complex adaptive social system that should maximize stakeholder, not shareholder, value — value to employees, customers, shareholders and others. We expand upon Russell Ackoff s direction to distribute value among stakeholders, to propose a schema of rules that guide the interactions among autonomous agents in the transactional environment of an enterprise. We define an enterprise as an organization and its transactional environment interacting with and adapting to each other. Enterprise behavior can only be understood in the context of this transactional environment where everything depends on everything else and interactions cannot be controlled, but can be influenced if they are guided by an understanding of the internal rules of the autonomous agents. The schema has four complementary rules (control, autonomy, return and value) derived from the work of Russell Ackoff and Michael Porter. The basic rules are applied in combination to eight stakeholder types derived from Richard Hopeman and Raymond McLeod (Leaders, Competitors, Customers, Public, Workers, Collaborators, Suppliers and Regulators). An enterprise can use this schema and rules in a process of stakeholder analysis to develop and continually refine strategies to encourage behaviors that benefit the enterprise and discourage behaviors that harm the enterprise. These strategies are implemented in a relationship management program in support of enterprise strategic management to consciously and explicitly shape the environment to reduce risks and increase opportunities for success.

    Scientists, politicians, the public, school children, our neighbours, you. All of these groups of people have a stake in CERN, and all are important to us.   The list of stakeholders in an organisation as large and complex as CERN is a long and ever lengthening one. Each group has its own specific interests and needs in terms of what kind of information it requires from CERN and how we should engage. It’s important, therefore, for us to ensure that we’re communicating optimally with everyone we care about and who cares about us. This is something that CERN has always taken seriously. The CERN Courier, for example, was first published in 1959 and we had a pro-active public information office right from the start. Today, our stakeholder relations are spread between several groups and teams, reflecting the nature of CERN today. But while we’re already doing a good job, I think we can do better by exploiting the synergies between these teams, and that’s wh...

    Full Text Available The present study investigated the germination and vigor of Caesalpinia echinata (Brazilwood seeds stored at negative temperatures. Recently harvested seeds were cryopreserved at -18º or -196ºC and periodically evaluated for germination, seed vigor and carbohydrate composition. The temperatures did not influence the germination percentages or vigor. The germination percentage decreased from 88% in recently harvested seeds to 60% after 730 days of storage. The different temperature and storage times tested did not affect the vigor seed germination as indicated by the measures of plant growth and survival. The different temperatures used did not cause changes in the carbohydrate composition. The tegument cell walls were rich in lignin, arabinose and xylose. The cytoplasm of the cotyledons and embryos had high levels of glucose, fructose, and sucrose. The cryopreservation technique here presented was effective in the conservation of Brazilwood seeds for the medium term.

This analysis assesses their association with longitudinal vigorous physical activity (PA in postmenopausal women of the Women's Health Initiative (WHI. Subjects include 73,485 women nationwide without history of cancer or cardiovascular disease (CVD, and no missing baseline optimism, cynical hostility, or PA data. The Life Orientation Test-Revised Scale measured optimism. A Cook Medley questionnaire subscale measured cynical hostility. Scale scores were divided into quartiles. Vigorous PA three times or more per week was assessed via self-report at study baseline (1994–1998 and through follow-up year 6. Descriptive analysis mapped lifetime trajectories of vigorous PA (recalled at ages 18, 25, 50; prospectively assessed at baseline, and 3 and 6 years later. Hierarchical generalized linear mixed models examined the prospective association between optimism, cynical hostility, and vigorous PA over 6 years. Models adjusted for baseline sociodemographic variables, psychosocial characteristics, and health conditions and behaviors. Vigorous PA rates were highest for most optimistic women, but fell for all women by approximately 60% between age 50 and study baseline. In adjusted models from baseline through year 6, most vs. least optimistic women were 15% more likely to exercise vigorously (p < 0.001. Cynical hostility was not associated with lower odds of longitudinal vigorous PA after adjustment. Results did not differ by race/ethnicity or socioeconomic status. Higher optimism is associated with maintaining vigorous PA over time in post-menopausal women, and may protect women's health over the lifespan.

    1994-03-01

    Stakeholder analysis allows analysts to identify how parties might be affected by government projects. This process involves identifying the likely impacts of a proposed action and stakeholder groups affected by that action. Additionally, the process involves assessing how these groups might be affected and suggesting measures to mitigate any adverse effects. Evidence suggests that the efficiency and effectiveness of government actions can be increased and adverse social impacts mitigated when officials understand how a proposed action might affect stakeholders. This report discusses how to conduct useful stakeholder analyses for government officials making decisions on energy-efficiency and renewable-energy technologies and their commercialization. It discusses methodological issues that may affect the validity and reliability of findings, including sampling, generalizability, validity, ``uncooperative`` stakeholder groups, using social indicators, and the effect of government regulations. The Appendix contains resource directories and a list of specialists in stakeholder analysis and involvement.

    Full Text Available Means of accommodation involve a wide range of social actors and agents, as well as different business models. Management strategies in this sector have been increasingly important for long-term sustainability and competitiveness of business organizations. This study aims to analyze the interactions between apart-hotels and their stakeholders to foster an improvement of services provided, aligning the interface of strategic management from the point of view of managers and their key stakeholders. It is an exploratory study, with qualitative chacter, along with multiple case studies of the following establishments: Travel Inn, Hotels Slaviero and Etoile george v. Brazilian enterprises, which manage lodging facilities with apart-hotel concepts, combining features that enable comparative analysis of the study. For conceptual understanding, this study was based on literature about stakeholders, taking the work of Freeman (1984 and Freeman et al (2010 as main references. The research was conducted through semi-structured interviews with managers of lodging facilities and their key stakeholders and through direct observation and documentation. We found that not all groups of influence are considered in the planning of service flats. However, the organizations surveyed indicated that the market has realized the importance of the groups that exert influence and are influenced by their goals, and are therefore increasingly alert for integration of such groups in their strategic planning.

  13. Open Innovation and Stakeholder Engagement

    Directory of Open Access Journals (Sweden)

    Robert Wayne Gould

    2012-09-01

    Full Text Available The paradox of open innovation lies in the conflict between the practical desire to reap the benefits of open innovation and concern over the risk that others will misappropriate those benefits. Stakeholder theory and recent developments in value creation through stakeholder engagement can assist with reconciliation of this inherent structural risk. The limitations of existing open innovation typologies are identified, and a process-based model of open innovation is proposed. The model is then expanded to include stakeholder engagement. When integrated with stakeholder engagement, open innovation processes can be understood to generate benefits beyond the acquisition of specific information sought from external experts. The addition of stakeholder engagement to the open innovation model allows for greater understanding and easier acceptance of the risks inherent in the open innovation process.

O rendimento biológico na antese e na maturação, a remobilização de nitrogênio, a eficiência de remobilização e de utilização de nitrogênio, a concentração de nitrogênio nos tecidos na maturação e a qualidade fisiológica das sementes produzidas, não foram afetados pela diferença nos níveis de vigor das sementes e pela variação na população de plantas. O rendimento de grãos e os componentes do rendimento não foram afetados pelo nível de vigor das sementes, embora as baixas populações de plantas tenham reduzido o rendimento de grãos. As plantas provenientes de sementes de menor vigor foram mais eficientes na alocação de produtos da fotossíntese nas sementes. A cultivar Embrapa 29 foi menos eficientes na acumulação de nitrogênio na biomassa da parte aérea na época da antese, e na biomassa da parte vegetativa aérea na época da maturação, do que a cultivar Embrapa 140.

    Full Text Available The development of technologies to increase stand establishment efficiency and seed vigor, as well as to maximize profits, is of fundamental importance for the sustainability of agriculture. Products based on humic substances, such as humic acids, have been recently used in Brazilian agriculture to produce seedlings with high vigor, which positively influences the establishment of the initial stand. Thus, this study aimed to evaluate the effect of treatment of corn seeds with a commercial humic acid-based product, Humykos® (18% of humic acid content, on germination and seedling vigor. The treatments consisted of six doses (0, 100, 200, 300, 400, and 500 mL 100 kg-1 seed of Humykos®, and the treated seeds were analyzed for germination and vigor (first count, emergence, emergence speed index, length, and dry mass of shoots and roots. Our results show that humic acid promotes greater seedling growth and increased shoot dry mass in corn; in addition, it has a positive influence on the emergence speed index up to a dose 158 mL 100 kg-1 seeds.

    2010-01-01

    Full Text Available Corporate communications represent a modern communications discipline used by businesses across the globe to communicate with key stakeholders. Chief executive officers and executive management teams strive to create, protect and advance corporate reputation through corporate communications. Further, by communicating with key stakeholders the company adequately prepares for good news and future problems. With the benefit of technology and greater transparency, corporations of the future will continue to use corporate communications approaches to advance their business. Company's reputation derives from the way stakeholders perceive the organization, how they think, feel or act towards it. It is therefore vital that organizations interested in developing and building their reputational capital; pay careful attention to the way they are perceived and that they manage the relationships with their various stakeholders like a strategic resource. Stakeholders represent both opportunity and threat for the organizations. For instance, if an institution has a good reputation with stakeholders they may provide the organization more latitude to operate. On the other hand a poor reputation may result in creating the legislative that can make it more difficult for an institution to operate.

    Williams, Paul T.

    2007-04-30

    We examined the dose-response relationship between changes in reported vigorous exercise (running distance, {Delta}km/wk) and self-reported physician diagnosed diabetes in 25,988 men followed prospectively for (mean {+-} SD) 7.8 {+-} 1.8 years. Logistic regression analyses showed that the log odds for diabetes declined significantly in relation to men's {Delta}km/wk (coefficient {+-} SE: -0.012 {+-} 0.004, P < 0.01), which remained significant when adjusted for BMI (-0.018 {+-} 0.003, P < 0.0001). The decline in the log odds for diabetes was related to the distance run at the end of follow-up when adjusted for baseline distance, with (-0.024 {+-} 0.005, P < 0.0001) or without (-0.027 {+-} 0.005, P < 0.0001) adjustment for BMI. Baseline distance was unrelated to diabetes incidence when adjusted for the distance at the end of follow-up. Compared to men who ran <8 km/wk at the end of follow-up, incidence rates in those who ran {ge} 8 km/wk were 95% lower between 35-44 yrs old (P < 0.0001), 92% lower between 45-54 yrs old (P < 0.0001), 87% lower between 55 and 64 years old (P < 0.0001), and 46% lower between 65-75 yrs old (P = 0.30). For the subset of 6,208 men who maintained the same running distance during follow-up ({+-}5 km/wk), the log odds for diabetes declined with weekly distance run (-0.024 {+-} 0.010, P = 0.02) but not when adjusted for BMI (-0.005 {+-} 0.010, P = 0.65). Conclusion: Vigorous exercise significantly reduces diabetes incidence, due in part to the prevention of age-related weight gain and in part to other exercise effects. Physical activity decreases the risk of type 2 diabetes [1-10]. Moderate and vigorous exercise are purported to produce comparable reductions in diabetes risk if the energy expenditure is the same [3,10]. The optimal physical activity dose remains unclear, however, with some [4-7] but not all studies [1,8,9] showing continued reduction in diabetes for high versus intermediate energy expenditures.

Mature fruits were harvested in the palm collection of the Instituto Agronomico in Campinas, Brazil. Depulped fruits were transported in impermeable packages to the Faculdade de Agronomia in Botucatu, where the seeds were dried. As the seed moisture decreased, germination, seedling length, electrical conductivity and moisture were measured. The seeds of A. alexandrae are recalcitrant, with high germination percentage (over 67% when undried (47% seed moisture. Lowering seed moisture below 31.5% reduced the germination rate significantly (<52.5%. Total germination failure was observed when seed moisture reached 15.1%. The electrical conductivity was the most sensitive vigor test to identify seed deterioration.

    Inadequate physical activity increases the risks related to several health problems in children; however, increasing physical activity mitigates these risks. In this study, we examined the relations between moderate-to-vigorous physical activity (MVPA) and several environmental conditions (attention, interactive play, alone, escape) with 4 preschool children. We compared the experimental conditions to a control condition and a naturalistic baseline according to a combined multielement and reversal design. Results indicated that all participants were most active in the interactive play condition and that the percentage of MVPA varied across experimental and control conditions. In addition, the frequency and duration of bouts of MVPA were greatest in the interactive play condition. The current study presents a methodology for the identification of environmental contingencies that support increased levels of MVPA in young children, and it holds promise for improving our understanding of the variables related to physical activity. © Society for the Experimental Analysis of Behavior.

  17. Vigorous Convection Underlies Pluto’s Surface Activity

    Against many expectations, New Horizons’ images of the surface of Pluto and Charon show seemingly young surfaces. On Pluto, images of an equatorial region south of the Tombaugh Regio reveal a mountain range with peaks jutting as high as 3,500 meters. The low concentration of craters for these mountains suggests an age of 100 million years, indicating that Pluto is geologically active. Other evidence for geologic activity includes a fault cross-cutting ridges, smooth lightly cratered plains with flow fronts, and a pair of apparent stratovolcanoes. Charon similarly possesses very few craters and a spectacular system of troughs. Both observations suggest the possible presence of active cryogeysers and cryovolcanoes. The underlying cause of modern tectonic and volcanic activity on any object is likely a vigorous mantle convection regime. We are thus led to consider what determines planetary vigor. While Pluto and Charon seem to be quite active, Ceres and the much larger Callisto seem to lack modern endogenic activity, even though all of these bodies are likely to possess water ice mantles.We coupled a parameterized convection model with a temperature dependent rheology for pure water ice, deducing a barely critical Rayleigh number of ~1600 for Pluto’s mantle and <1000 for Charon, suggesting that a water ice mantle alone may be insufficient to support vigorous convection in these bodies. However, in the outer solar system, other volatiles may have condensed. Ammonium hydrate has been reported on the surface of Charon. At temperatures above the eutectic (176 K), Durham et al. (1993) showed that NH3 lowers the viscosity of water ice by 4 orders of magnitude. Our model indicates that, with NH3, the mean temperature of the mantle of Pluto is at the eutectic and its Ra ~ 10^4. The presence of NH3 dramatically increases the vigor of convection for the two bodies and suggests that ammonia-water slurries are the basis for Pluto’s volcanism. We propose that the presence or

    The ecosystem services framework has enabled the broader public to acknowledge the benefits nature provides to different stakeholders. However, not all stakeholders benefit equally from these services. Rather, power relationships are a key factor influencing the access of individuals or groups to ecosystem services. In this paper, we propose an adaptation of the "cascade" framework for ecosystem services to integrate the analysis of ecological interactions among ecosystem services and stakeholders' interactions, reflecting power relationships that mediate ecosystem services flows. We illustrate its application using the floodplain of the River Piedra (Spain) as a case study. First, we used structural equation modelling (SEM) to model the dependence relationships among ecosystem services. Second, we performed semi-structured interviews to identify formal power relationships among stakeholders. Third, we depicted ecosystem services according to stakeholders' ability to use, manage or impair ecosystem services in order to expose how power relationships mediate access to ecosystem services. Our results revealed that the strongest power was held by those stakeholders who managed (although did not use) those keystone ecosystem properties and services that determine the provision of other services (i.e., intermediate regulating and final services). In contrast, non-empowered stakeholders were only able to access the remaining non-excludable and non-rival ecosystem services (i.e., some of the cultural services, freshwater supply, water quality, and biological control). In addition, land stewardship, access rights, and governance appeared as critical factors determining the status of ecosystem services. Finally, we stress the need to analyse the role of stakeholders and their relationships to foster equal access to ecosystem services.

    The metabolite content of a seed and its ability to germinate are determined by genetic makeup and environmental effects during development. The interaction between genetics, environment and seed metabolism and germination was studied in 72 tomato homozygous introgression lines (IL) derived from Solanum pennelli and S. esculentum M82 cultivar. Plants were grown in the field under saline and fresh water irrigation during two consecutive seasons, and collected seeds were subjected to morphological analysis, gas chromatograph-mass spectrometry (GC-MS) metabolic profiling and germination tests. Seed weight was under tight genetic regulation, but it was not related to germination vigor. Salinity significantly reduced seed number but had little influence on seed metabolites, affecting only 1% of the statistical comparisons. The metabolites negatively correlated to germination were simple sugars and most amino acids, while positive correlations were found for several organic acids and the N metabolites urea and dopamine. Germination tests identified putative loci for improved germination as compared to M82 and in response to salinity, which were also characterized by defined metabolic changes in the seed. An integrative analysis of the metabolite and germination data revealed metabolite levels unambiguously associated with germination percentage and rate, mostly conserved in the different tested seed development environments. Such consistent relations suggest the potential for developing a method of germination vigor prediction by metabolic profiling, as well as add to our understanding of the importance of primary metabolic processes in germination.

    Full Text Available Luminosity influences seed emergence in the initial development of papaya plants, being necessary the identification of the ideal irradiance level for plantule establishment and formation of vigorous seedlings. This study aimed to evaluate the seed emergence and seedlings vigor of four papaya genotypes, under different irradiance levels. Carica papaya L. seeds, from the Caliman 01 hybrid, Golden THB, triple hybrid and JS12 x Waimanalo hybrid genotypes, were evaluated under four irradiance levels (60 µmol m-2 s-1, 130 µmol m-2 s-1, 580 µmol m-2 s-1 and 1,200 µmol m-2 s-1. A completely randomized design, in a 4x4 split-plot scheme, with four replications, was used. The emergence percentage and speed index were evaluated. The seedlings were measured at 45 and 120 days after sowing (DAS, concerning root and shoot length and dry matter, being calculated the root/shoot ratio and absolute growth rate at 120 DAS. The full sun affected emergence, while the low irradiance affected seedling growth. The intermediate irradiance (130 µmol m-2 s-1 and 580 µmol m-2 s-1 was more suitable to the development of papaya seedlings up to 120 DAS. The Golden THB genotype was more sensitive to high irradiance, while the Caliman 01 and JS12 x Waimanalo hybrids tolerated the full sun condition.

  6. Does browsing reduce shrub survival and vigor following summer fires?

    Science.gov (United States)

    Fulbright, Timothy E.; Dacy, Emily C.; Drawe, D. Lynn

    2011-01-01

    Periodic fire is widely hypothesized to limit woody plant encroachment in semiarid grasslands. In southern Texas, however, most of the woody plants that have invaded grasslands during the past two centuries are resistant to fire. We hypothesized that browsing by Odocoileus virginianus increases mortality of palatable shrubs and reduces vigor of shrubs following fire. We randomly selected ten pairs of each of three shrub species -Condalia hookeri, Acacia farnesiana, and Celtis ehrenbergiana - in each of three locations before prescribed burns during summer 2001. Following burns, we used a wire fence to protect one shrub of each pair from browsing. We estimated intensity of O. virginianus browsing and number and height of sprouts 4, 12, 20, 30, 38, and 47 weeks post-fire. We determined shrub height, survival, and biomass one year post-fire. Averaged across species, browsing intensity on unfenced shrubs was greater (LS Means, P 0.05) one year post-burn. Browsing by O. virginianus at the intensity in our study does not increase mortality or reduce vigor of C. hookeri, A. farnesiana, and Condalia ehrenbergiana producing new growth following destruction of aboveground tissues by a single fire compared to shrubs that are not browsed following fire.

  17. Fallen uterus: social suffering, bodily vigor, and social support among women in rural Mexico.

    Science.gov (United States)

    Smith-Oka, Vania

    2014-03-01

    This article focuses on rural indigenous Mexican women's experiences with uterine prolapse, particularly the illness's expression of social suffering. Drawing on ethnographic research conducted during 2004-2005 and 2007 in a Nahua village in the state of Veracruz, the article analyzes the multifactorial nature of women's social suffering. Results show that the roots of uterine displacement for the women lie in lack of social relations and in perceptions of bodily vigor. Additionally, inequality present in the women's interactions with mainstream Mexico brings into focus the larger structural factors that shape their reproductive health. The implications of research on the effect of social support on women's embodiment of social suffering can extend beyond one illness, linking it to broader issues shaping the health of marginalized populations. © 2014 by the American Anthropological Association.

  18. Vine vigor components and its variability - relationship to wine composition

    2015-04-01

    It was pointed out that a high spatial variability for canopy size and yield would exist within a vineyard but a high temporal stability over the years was observed. Furthermore, a greater variability in grape phenolics than in sugars and pH was detected within a vineyard. But the link between remote sensing indices and quality parameters of grapes is still unclear. Indeed, though in red grape varieties anthocyanins content was spatially negatively correlated to vigor parameters, it seemed that yield, Normalized Difference Vegetation Index (NDVI) and Plant Cell Density (PCD) indices were poorly correlated. Moreover, the link to quality parameters of wines remains uncertain. It was shown that more vigorous vines would lead to wines with less tannins while anthocyanins in wines would be highest when the vines were balanced but the question is if vine size or architecture, yield or nitrogen assimilation would play major contribution to those differences. The general scope of our project was to provide further knowledge on the relationship between vigor parameters and wine composition and relate these to the information gained by remote sensing. Variability in a 0.15 ha vineyard of Pinot noir planted in 2003 and grafted on SO4 rootstock at Geisenheim (Germany) was followed. Vine vigor was assessed manually for each of the 400 vines (cane number, pruning weight, trunk diameter) together with yield parameters (number of bunches per vine, crop yield). Leaf composition was assessed with a hand-held optical sensor (Multiplex3® [Mx3] (Force-A, Orsay, France) based on chlorophyll fluorescence screening providing information on leaf chlorophyll (SFR_G) and nitrogen (NBI_G) content. A micro-scale winemaking of single vines with a 3 factorial design on yield (L low, M middle, H high), SFRG (L, M, H) and canopy size (pruning weight, trunk diameter) (L, M, H) was performed for 2013 and 2014 to completely reflect variability. Wine tannin concentration represented the highest

  19. Does vigorous exercise have a neuroprotective effect in Parkinson disease?

    Science.gov (United States)

    Ahlskog, J Eric

    2011-07-19

    Parkinson disease (PD) is progressive, with dementia and medication-refractory motor problems common reasons for late-stage nursing-home placement. Increasing evidence suggests that ongoing vigorous exercise/physical fitness may favorably influence this progression. Parkinsonian animal models reveal exercise-related protection from dopaminergic neurotoxins, apparently mediated by brain neurotrophic factors and neuroplasticity (predicted from in vitro studies). Similarly, exercise consistently improves cognition in animals, also linked to enhanced neuroplasticity and increased neurotrophic factor expression. In these animal models, immobilization has the opposite effect. Brain-derived neurotrophic factor (BDNF) may mediate at least some of this exercise benefit. In humans, exercise increases serum BDNF, and this is known to cross the blood-brain barrier. PD risk in humans is significantly reduced by midlife exercise, documented in large prospective studies. No studies have addressed whether exercise influences dementia risk in PD, but exercised patients with PD improve cognitive scores. Among seniors in general, exercise or physical fitness has not only been associated with better cognitive scores, but midlife exercise significantly reduces the later risk of both dementia and mild cognitive impairment. Finally, numerous studies in seniors with and without dementia have reported increased cerebral gray matter volumes associated with physical fitness or exercise. These findings have several implications for PD clinicians. (1) Ongoing vigorous exercise and physical fitness should be highly encouraged. (2) PD physical therapy programs should include structured, graduated fitness instruction and guidance for deconditioned patients with PD. (3) Levodopa and other forms of dopamine replenishment therapy should be utilized to achieve the maximum capability and motivation for patients to maintain fitness.

  5. Guidelines A Primer for Communicating Effectively with NABIR Stakeholders

    Energy Technology Data Exchange (ETDEWEB)

    Weber, James R.; Word, Charlotte J.; Bilyard, Gordon R.

    2002-03-15

    The purpose of this report is to help scientists communicate with stakeholders and the public (primarily nonscientists) about fundamental science research. The primary audience for this report is scientists involved in the Natural and Accelerated Bioremediation Research (NABIR) program of the U.S. Department of Energy. However, the information and insights in the report that are not program-specific should be helpful to scientists in other fundamental science research programs. The report first discusses why scientists should talk to stakeholders and the public, and the challenges associated with discussing the NABIR program. It is observed that communication initiatives can be characterized by three factors: relationships in the social environment, views of what constitutes communication, and accepted forms of communication practices and products. With a focus on informal science communication, recent efforts to gauge public understanding of science and the factors that affect public trust of science institutions are discussed. The social bases for scientist-nonscientist interactions are then examined, including possible sources of distrust and difficulties in transferring discussions of fundamental science from classrooms (where most of the public first learns about science) to public forums. Finally, the report contains specific suggestions for preparing, meeting, and following up on public interactions with stakeholders and the public, including themes common to public discussions of NABIR science and features of scientist-nonscientist interactions observed in interpersonal, small group, and large group interactions between NABIR scientists and stakeholders. A Quick Preparation Guide for Meeting NABIR Stakeholders is provided immediately following the Summary. It condenses some of the information and advice found in the text of the report.

  6. Influence of Harvest Aid Herbicides on Seed Germination, Seedling Vigor and Milling Quality Traits of Red Lentil (Lens culinaris L.).

    Subedi, Maya; Willenborg, Christian J; Vandenberg, Albert

    2017-01-01

    Most red lentil produced worldwide is consumed in dehulled form, and post-harvest milling and splitting qualities are major concerns in the secondary processing industry. Lentil producers in northern temperate regions usually apply pre-harvest desiccants as harvest aids to accelerate the lentil crop drying process and facilitate harvesting operations. This paper reports on field studies conducted at Scott and Saskatoon, Saskatchewan, Canada in the 2012 and 2013 cropping seasons to evaluate whether herbicides applied as harvest aids alone or tank mixed with glyphosate affect seed germination, seedling vigor, milling, and splitting qualities. The site-year by desiccant treatment interaction for seed germination, vigor, and milling recovery yields was significant. Glyphosate applied alone or as tank mix with other herbicides (except diquat) reduced seed germination and seedling vigor at Saskatoon and Scott in 2012 only. Pyraflufen-ethyl (20 g ai ha-1) applied with glyphosate as well as saflufenacil (36 g ai ha-1) decreased dehulling efficiency, while saflufenacil and/or glufosinate with glyphosate reduced milling recovery and football recovery, although these effects were inconsistent. Application of diquat alone or in combination with glyphosate exhibited more consistent dehulling efficiency gains and increases in milling recovery yield. Significant but negative associations were observed between glyphosate residue in seeds and seed germination (r = -0.84, p < 0.001), seed vigor (r = -0.62, p < 0.001), dehulling efficiency (r = -0.55, p < 0.001), and milling recovery (r = -0.62, p < 0.001). These results indicate application of diquat alone or in combination with glyphosate may be a preferred option for lentil growers to improve milling recovery yield.

    The purpose of this quantitative diary study was to investigate daily vigor and exhaustion using a person-centered approach. The study also investigated whether and how experiences of vigor and exhaustion relate to a state of being recovered. A total of 256 Finnish employees filled in a diary questionnaire during five consecutive workdays. Vigor and exhaustion showed strong negative interdependence within and between days. However, by applying a person-centered analysis, we were able to differentiate three groups with meaningful variation in vigor and exhaustion. The groups were labeled as Constantly vigorous (n = 179), Concurrently vigorous and exhausted (n = 30) and Constantly exhausted (n = 43). The vigor-exhaustion groups were also characterized by their recovery experiences: The Constantly vigorous employees recovered well from work strain during the workweek whereas the Constantly exhausted group recovered poorly. Overall, while the results indicate that, typically, vigor and exhaustion are exclusive experiences, it is also possible for them to be experienced simultaneously from day to day at the moderate levels. Thus, positive and negative experiences may co-occur.

    Full Text Available Massaging the newborn has been a tradition in India and other Asian countries since time immemorial. There are many benefits of traditional oil massage. Although considered as a safe practice with no significant harmful effects, rarely if performed improperly baby may end up having adverse effects like fracture. We report a forearm fracture in a neonate following vigorous oil massage. A 15 days old male baby was brought with the complaints of reduced movement, pain and swelling in right forearm of one day duration. The baby was born full term to a non consanguineous parent. His birth weight was 3.12kg and APGAR score was good. Post natal period was uneventful except for neonatal hyperbilirubinemia for which he had received phototherapy. At home he was getting daily oil massage and bath by traditional techniques. On examination there was diffuse, tender swelling on the ventral aspect of right forearm which was firm in consistency and there was paucity of movement. X ray revealed fracture of proximal radius and middle third of ulna. Skeletal survey did not reveal any other fracture. Baby was treated with a short arm, below the elbow cast. Absence of family history and no other bone involvement made osteogenesis imperfecta and child abuse less likely. In conclusion simple causes like oil massage also to be kept in mind in dealing with neonatal fractures.

    Red supergiant stars represent a late stage of the evolution of stars more massive than about nine solar masses, in which they develop complex, multi-component atmospheres. Bright spots have been detected in the atmosphere of red supergiants using interferometric imaging. Above the photosphere of a red supergiant, the molecular outer atmosphere extends up to about two stellar radii. Furthermore, the hot chromosphere (5,000 to 8,000 kelvin) and cool gas (less than 3,500 kelvin) of a red supergiant coexist at about three stellar radii. The dynamics of such complex atmospheres has been probed by ultraviolet and optical spectroscopy. The most direct approach, however, is to measure the velocity of gas at each position over the image of stars as in observations of the Sun. Here we report the mapping of the velocity field over the surface and atmosphere of the nearby red supergiant Antares. The two-dimensional velocity field map obtained from our near-infrared spectro-interferometric imaging reveals vigorous upwelling and downdrafting motions of several huge gas clumps at velocities ranging from about -20 to +20 kilometres per second in the atmosphere, which extends out to about 1.7 stellar radii. Convection alone cannot explain the observed turbulent motions and atmospheric extension, suggesting that an unidentified process is operating in the extended atmosphere.

    2010-09-01

    Full Text Available This study was conducted in the laboratory and the field to examine the effects of ascorbic acid treatment on germination and seedling growth under drought stress. The laboratory works consisted of two experiments and were designed to determine the critical osmotic potential of maize and to determine the optimum ascorbic acid concentration. The field study was designed to examine the effects of soaking seed in ascorbic acid on seedling growth under drought stress. Drought condition was simulated by PEG-6000 and regulation of water treatment. During the first experiment, interactions of both osmotic potential and varieties were significant at all variables. Germination percentage and speed of germination were significantly decreased by increasing of osmotic potential. The second experiment showed that interactions of both factors were significant at all variables except vigor index, the length of shoot, primary, and seminal root. The results showed that the ascorbic acid treatment improved the germination percentage, the speed of germination and the vigor index compared with the control, besides the increase in length of shoot, primary and seminal root and number of seminal root. However, the best result was showed by 55 mM ascobic acid. The result of field experiment showed that interactions were not always significant and 55 mM ascorbic acid treatment increased the seedling height, the number of leaves and leaf area but it had no effect on the water deficit and the root length.

    National physical activity standards call for all children to accumulate 60 minutes/day of moderate to vigorous physical activity (MVPA). The contribution of summer day camps toward meeting this benchmark is largely unknown. The purpose of this study was to provide estimates of children's MVPA during summer day camps. Children (n=1,061, 78% enrollment; mean age, 7.8 years; 46% female; 65% African American; 48% normal weight) from 20 summer day camps wore ActiGraph GT3x+ accelerometers on the wrist during camp hours for up to 4 non-consecutive days over the summer of 2015 (July). Accumulated MVPA at the 25th, 50th, and 75th percentile of the distribution was estimated using random-effects quantile regression. All models were estimated separately for boys and girls and controlled for wear time. Minutes of MVPA were dichotomized to ≥60 minutes/day of MVPA or summer day camps, boys (n=569) and girls (n=492) accumulated a median of 96 and 82 minutes/day of MVPA, respectively. The percentage of children meeting 60 minutes/day of MVPA was 80% (range, 41%-94%) for boys and 73% (range, 30%-97%) for girls. Summer day camps are a setting where a large portion of boys and girls meet daily physical activity guidelines.

    Collier, Zachary A; Bates, Matthew E; Wood, Matthew D; Linkov, Igor

    2014-10-15

    Dredging and disposal issues often become controversial with local stakeholders because of their competing interests. These interests tend to manifest themselves in stakeholders holding onto entrenched positions, and deadlock can result without a methodology to move the stakeholder group past the status quo. However, these situations can be represented as multi-stakeholder, multi-criteria decision problems. In this paper, we describe a case study in which multi-criteria decision analysis was implemented in a multi-stakeholder setting in order to generate recommendations on dredged material placement for Long Island Sound's Dredged Material Management Plan. A working-group of representatives from various stakeholder organizations was formed and consulted to help prioritize sediment placement sites for each dredging center in the region by collaboratively building a multi-criteria decision model. The resulting model framed the problem as several alternatives, criteria, sub-criteria, and metrics relevant to stakeholder interests in the Long Island Sound region. An elicitation of values, represented as criteria weights, was then conducted. Results show that in general, stakeholders tended to agree that all criteria were at least somewhat important, and on average there was strong agreement on the order of preferences among the diverse groups of stakeholders. By developing the decision model iteratively with stakeholders as a group and soliciting their preferences, the process sought to increase stakeholder involvement at the front-end of the prioritization process and lead to increased knowledge and consensus regarding the importance of site-specific criteria.

    Full Text Available When developing organizations their stakeholders are increasingly involved in structuring and adapting work processes. Understanding process design as open learning facility allows promoting organizational structures and change proposals in an informed and bottom-up way. In this work the constitutive elements and processes of such a participatory infrastructure are studied from an open educational resource and open access perspective on the individual and collective level. Besides providing OER the focus is on generating work process-relevant knowledge from an individual perspective, disseminating it for collective reflection, and propagating it to organizational practice. Creating, sharing, and finally, processing this knowledge in open organizational learning environments targeting business process development requires federating social media, semantic content management, business process modelling and execution systems. Stakeholders contribute through (i articulating proposals on how to organize work, (ii annotating content in the course of exploiting, sharing and reflecting on these proposals, and (iii executing process models to experience a certain structure of work. Applying this approach in a healthcare setting could reveal organizational benefits due to the contextualized and traceable sharing of (generated content with other stakeholders. In particular, the interactive execution of work processes from each stakeholder’s perspective (enabled through subject orientation ensures timely involvement in development fitting stakeholder capabilities and needs.

Se utilizaron semillas de soja de diferentes cultivares en 1997 y 1998, las cuales fueron sometidas a la prueba de germinación y diferentes pruebas de vigor: envejecimiento acelerado; conductividad eléctrica; deterioro controlado y tetrazolio. El deterioro controlado en semillas con 22% de humedad mostró ser un mejor indicador de la disminución del vigor de la semilla de soja que el envejecimiento acelerado. La conductividad eléctrica en semillas individuales podría ser considerada una buena prueba de vigor para detectar alteraciones producidas en las membranas citoplasmáticas en un estadio temprano del deterioro de las semillas. La clasificación de la viabilidad y el vigor a través de la prueba de tetrazolio está dada por el lugar donde se produce el daño y no por el tipo de daño que sufre la semilla.The objective of this work was to study soybean (Glycine max L. Merrill seed alterations produced by deterioration using different vigor tests. Soybean seeds of different cultivars were used in 1997 and 1998, which were submitted to standard germination test and the vigor tests: accelerated aging; electric conductivity; controlled deterioration and tetrazolium. The controlled deterioration with an elevation of the seed humidity to 22%, showed to be a better indicator of the diminishing of soybean seed vigor than the accelerated aging. The electric conductivity in individual seeds would be considered a good vigor test to detect the alterations produced in the cytoplasmic membranes in an early stage of the seed deterioration. The tetrazolium test by the evaluation of the different kinds of injuries suffered by the seeds, depends on the place where the seed is damaged not on the kind of injury suffered by the seed.

    Full Text Available Organizations inform stakeholders about their current and future activities, processes, created value, strategic intentions, and other information that may influence the established relationships. Organizations choose to communicate with stakeholders by different means and in varied ways. The annual report represents a way of communicating between companies and their stakeholders, and it is offering comprehensive information about how companies operates and creates value. The business model is an emerging concept in management literature and practice. The concept describes the logic by which a organization creates, maintains and delivers value for its stakeholders. Through annual reports organisations can communicate to stakeholders information about their business models.We investigated how information about business models is explicitly communicated through annual reports, and how this information is reffering to stakeholders. Our paper aims to reveal which stakeholders are more often mentioned when organizations are communicating about business models through annual reports. This approach shows the attention degree given by organizations to stakeholders. We perceived this from a strategic point of view, as a strategic signal. Thus, we considered if the stakeholder is mentioned more frequent in the communicated message it has a greater role in communication strategy about business model. We conducted an exploratory research and have realized a content analysis.The analysed data consist in over a thousand annual reports from 96 organizations. We analysed the informations transmitted by organizations through annual reports. The annual reports were for a time period of 12 years. Most of the selected companies are multi-business, and are operating in different industries. The results show the stakeholder’s hierarchy based on how often they were mentioned in the communicated messages about business models through annual reports. Based on our

  13. Vigorous exercise and the population distribution of bodyweight

    Energy Technology Data Exchange (ETDEWEB)

    Williams, Paul T.

    2002-09-18

    Background: While the benefits of vigorous exercise on body weight and regional adiposity are well established, whether these benefits affect equally the highest and lowest portions of the weight distribution has not been previously reported. The impact of exercise on the more extreme body weights and body circumferences is clinically important because these values represent individuals at greatest health risk. Method: We divided self-reported weights and body circumferences from a cross-sectional sample of 7,288 male and 2,359 female runners into five strata according to the distances run per week and within each stratum determined the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles. Then Least-squares regression was then employed at each percentile to determine the dose-response relationship between running distance and adiposity. Results: Per kilometer run per week, the associated decline for body mass index (BMI) was three-fold greater at the 95th than at the 5th percentile in men, and nine-fold greater at the 95th than the 5th percentile in women (all P<0.001). Reported waist circumference also declined more sharply at the 95th percentile than at the 5th percentile in men (-0.13/261 0.02 versus -0.06 plus or minus 0.01 cm per km/wk) and women (-0.18 plus or minus 0.04 versus -0.05 plusor minus 0.01 cm per km/wk). In women, both hip and chest circumferences declined more sharply per kilometer run at the 95th percentile than at the 5th percentile. Conclusions: These results support the hypothesis that running promotes the greatest weight loss specifically in those individuals who have the most to gain from losing weight. Comparisons based on average BMI or average body circumferences are likely to underestimate the health benefits of running because of the J-shaped relationship between adiposity and mortality. Whether the observed associations are primarily due to exercise-induced weight loss or self-selection remains to be determined.

    Research priorities, defined by multiple stakeholders, can proximally facilitate the coordination of research projects and national and international cooperation and distally further improve the quality of physiotherapy practice. The aim of this study was therefore to establish physiotherapy research priorities in Switzerland considering multiple stakeholders' opinions. A mixed methods design was chosen. For a qualitative identification of physiotherapy research topics, 18 focus group discussions and 23 semi-structured interviews/written commentaries were conducted. For the quantitative analysis, 420 participants prioritized research topics using a two-round Delphi questionnaire survey. The following stakeholder groups were surveyed in the German-speaking, French-speaking and Italian-speaking regions of Switzerland: physiotherapy researchers, practitioners and educators, representatives of patient organizations, public health organizations, health insurers, physicians, nurses, occupational therapists and other health professionals, as well as physical educators. The top five overall physiotherapy research priorities identified were as follows: physiotherapy treatment, physiotherapy assessment and diagnosis, prevention, physiotherapist-patient interaction and physiotherapy professional education at the bachelor level. With regard to diagnostic groups, the highest priorities were placed on musculoskeletal disorders, neurology, orthopaedics, geriatrics and ergonomics/occupational health. Consensus was moderate to high, and only few differences between stakeholder groups were revealed. Research directly related to physiotherapy treatment is of highest priority. It should focus on diagnostic groups related to chronicity in anticipation of demographic changes. Multidisciplinary networks for research and practice, alongside sound coordination of research projects, should increase the impact of physiotherapy research.

    This study examined how leader relational behaviors (i.e., relational leadership) cultivate bonding social capital among organizational members and the way bonding social capital augments feelings of vigor at work. In addition, the authors examined how vigor enhances employee job performance. Using a sample of 209 participants in Israeli community centers, the results of structural equation modeling indicate a 2-stage mediation model in which leader relational behaviors are positively related to bonding social capital; this, in turn, results in feelings of vigor, which are positively associated with manager ratings of employee job performance.

From 1999 to 2006, eight medical schools in Vietnam worked together to change the curriculum and teaching for general medical students to make it more community oriented. This paper describes the factors that motivated the different stakeholders to participate in curriculum change and teaching in Vietnamese medical schools and the activities to address those factors and have sustainable contributions from all relevant stakeholders. Case study analysis of contributions to the change process, using reports, interviews, focus group discussions and surveys and based on Herzberg's Motivation Theory to analyze involvement of different stakeholders. Different stakeholders were motivated by selected activities, such as providing opportunities for non-university stakeholders to share their opinions, organizing interactions among university stakeholders, stimulating both bottom-up and top-down inputs, focusing on learning from each other, and emphasizing self-motivation factors. The Herzberg Motivation theory helped to identify suitable approaches to ensure that teaching topics, materials and assessment methods more closely reflected the health care needs of the community. Other medical schools undertaking a reform process may learn from this experience.

    The introduction of new information technology in organizations seems to lead to mixed results in practice. Innovation adoption success is dependent on user commitment and absorption of the innovation in work processes. For that reason, much can be gained in insights in the role of stakeholders during innovation adoption. In this article we are presenting an evaluation method for stakeholder dynamics during the IT based innovation journey in relation to innovation adoption predictors. The method covers two evaluation elements of these stakeholder dynamics; (a) the changing nature of stakeholder salience and changing role involvements of stakeholders on the one hand, and (b) the changing nature of stakeholder-innovation interaction during the adoption processes on the other. It is argued that a stakeholder's capacity and intentions together determine his role involvement and influence on innovation adoption and thus its decision making unit membership. To further enhance usability of the described method, we propose the use of structured implementation activities and their effect during different phases of the innovation journey on the decision making unit as constructed through stakeholder analysis.

    This paper aims to create a model for evaluating organizational change initiatives from a stakeholder resistance viewpoint. The paper presents a model to evaluate change projects and their expected benefits. Factors affecting the challenge to implement change were defined based on stakeholder theory literature. The authors test the model's practical validity for screening change initiatives to improve operating room productivity. Change initiatives can be evaluated using six factors: the effect of the planned intervention on stakeholders' actions and position; stakeholders' capability to influence the project's implementation; motivation to participate; capability to change; change complexity; and management capability. The presented model's generalizability should be explored by filtering presented factors through a larger number of historical cases operating in different healthcare contexts. The link between stakeholders, the change challenge and the outcomes of change projects needs to be empirically tested. The proposed model can be used to prioritize change projects, manage stakeholder resistance and establish a better organizational and professional competence for managing healthcare organization change projects. New insights into existing stakeholder-related understanding of change project successes are provided.

    Public and stakeholder engagement can improve the quality of both research and policy decision making. However, such engagement poses significant methodological challenges in terms of collecting and analysing input from large, diverse groups. To explain how online approaches can facilitate iterative stakeholder engagement, to describe how input from large and diverse stakeholder groups can be analysed and to propose a collaborative learning framework (CLF) to interpret stakeholder engagement results. We use 'A National Conversation on Reducing the Burden of Suicide in the United States' as a case study of online stakeholder engagement and employ a Bayesian data modelling approach to develop a CLF. Our data modelling results identified six distinct stakeholder clusters that varied in the degree of individual articulation and group agreement and exhibited one of the three learning styles: learning towards consensus, learning by contrast and groupthink. Learning by contrast was the most common, or dominant, learning style in this study. Study results were used to develop a CLF, which helps explore multitude of stakeholder perspectives; identifies clusters of participants with similar shifts in beliefs; offers an empirically derived indicator of engagement quality; and helps determine the dominant learning style. The ability to detect learning by contrast helps illustrate differences in stakeholder perspectives, which may help policymakers, including Patient-Centered Outcomes Research Institute, make better decisions by soliciting and incorporating input from patients, caregivers, health-care providers and researchers. Study results have important implications for soliciting and incorporating input from stakeholders with different interests and perspectives. © 2015 The Authors.

    This report concerning Swedish nuclear waste management has been produced as part of a cross national research project: CARL - A Social Science Research Project into the Effects of Stakeholder involvement on Decision-Making in Radioactive Waste Management. Besides Sweden, the participating countries are Belgium, Canada, Finland, Slovenia and United Kingdom. A social science research team, working for three years, is in the first phase conducting research in their own countries in order to produce 6 country reports. During the next years the focus will shift to comparisons of stakeholder involvement practices in the participating countries. The report addresses current practices of Swedish nuclear waste management and their historical development. The main focus is on past, current and emerging patterns of stakeholder involvement in the siting of a deep repository for the final disposal of Sweden's spent nuclear fuel. The general questions attended to in the report are: Who are the main stakeholders, and how have they emerged and gained recognition as such? What are the issues currently subject to stakeholder involvement and how have these been decided upon? How is stakeholder involvement organized locally and nationally and how has this changed over time? How has stakeholder involvement gained acceptance as an activity of value in the siting of major waste facilities? The report have attempted to show the development of stakeholder involvement in the siting of a final repository for Sweden's spent nuclear fuel as resembling something other than a straightforward linear process of improvement and refinement. Stakeholder involvement has developed, over the past 15 years or so, into something more like a patchwork of different shapes and forms. Some of the forces that may well contribute to the further elaboration of the patchwork of stakeholder involvement have been pointed out, contingently modifying once more its overall colour and orientation.

    van Ast, J. A.; Boot, S. P.

    In the new framework directive, public information and consultation are main ele- ments in the procedure towards River Basin Management Plans. In general decision making in integrated water management should not be limited to the application of models and desk study. All important decisions need interaction with societal actors. These stakeholders have visions, ideas, patterns of behaviour and solutions for per- ceived problems. For example, farmer organisations, environmental groups and house- owners associations all have different ideas about measures that change the physical, chemical or biological characteristics of a river basin. Well- organised interaction has two main advantages: 1. The quality of the decision will be higher because specific knowledge of involved people and their different views are being taken into consider- ation. 2. The interaction enables exchange of information which can lead to a better understanding of the ins and outs of the specific situation and in this way contribute to public support. There are different ways for operationalisation of public informa- tion and consultation, like interactive workshops, internet assessment and interview rounds with key players. In this paper some of the different methods of interaction with stakeholders are elaborated. The aim is to improve the quality of integrated water management in river basins.

    Beginning in early 1995, U.S. Department of Energy began an experiment to link tribal and stakeholder representatives into technology assessment activities related to an Integrated Nonthermal Treatment System (INTS) study. The INTS study moved outside the framework of after-the-fact public involvement by providing the opportunity for technical and non-technical stakeholders alike to work together in the early predecision stages of the criteria development and assessment of options for innovative mixed waste treatment. The stakeholders gained an appreciation of the intense level of effort required to complete such an analysis. The engineers and scientists conducting the systems analyses had the opportunity (some for the first time) to learn more about tribal and stakeholder issues and how they might apply to the technical tasks related to technology assessment and selection.

    Soil erosion processes in vineyards, beyond surface runoff and sediment transport, have a strong effect on soil organic carbon (SOC) loss and redistribution along the slope. Variation in SOC across the landscape can determine differences in soil fertility and vine vigor. The goal of this research was to analyze the interactions among vines vigor, sediment delivery and SOC in a sloping vineyard located in Sicily. Six pedons were studied along the slope by digging 6 pits up to 60cm depth. Soil was sampled every 10cm and SOC, water extractable organic carbon (WEOC) and specific ultraviolet absorbance (SUVA) were analyzed. Erosion rates, detachment and deposition areas were measured by the pole height method which allowed mapping of the soil redistribution. The vigor of vegetation, expressed as Normalized Difference Vegetation Index (NDVI), derived from high-resolution satellite multispectral data, was compared with measured pruning weight. Results confirmed that soil erosion, sediment redistribution and SOC across the slope was strongly affected by topographic features, slope and curvature. The erosion rate was 16Mgha -1 y -1 since the time of planting (6years). SOC redistribution was strongly correlated with the detachment or deposition areas as highlighted by pole height measurements. The off-farm SOC loss over six years amounted to 1.2MgCha -1 . SUVA 254 values, which indicate hydrophobic material rich in aromatic constituents of WEOC, decreased significantly along the slope, demonstrating that WEOC in the detachment site is more stable in comparison to deposition sites. The plant vigor was strongly correlated with WEOC constituents. Results demonstrated that high resolution passive remote sensing data combined with soil and plant analyses can survey areas with contrasting SOC, soil fertility, soil erosion and plant vigor. This will allow monitoring of soil erosion and degradation risk areas and support decision-makers in developing measures for friendly

    Brief classroom-based episodes of physical activity (active lesson breaks, ALBs) have improved schoolchildren's classroom behaviors in some studies, and may also increase the likelihood of children meeting the recommended daily minutes of moderate to vigorous physical activity (MVPA). However, there is emerging evidence that increases in physical activity at particular times of the day may lead to compensatory declines at other times. This study explored evidence for compensatory declines in response to a 10 min ALB during the school day. Thirty-eight 12-year-old boys from a single elementary school completed intervention and control conditions in a cross-over design, with each phase lasting one week. The intervention consisted of a single 10-min active lesson break delivered on each of three days in the intervention week. Twenty-four hour accelerometry was used to quantify moderate and vigorous physical activity. ALBs increased in-school MVPA by 5.8 min (p .05), However, vigorous physical activity increased significantly over the whole day (11.2 vs 8.9 min, p = .0006). A brief episode of classroom-based play led to a modest increase in vigorous physical activity in elementary school students, but did not increase MVPA across the day.

    The relationships between variations in grapevine (Vitis vinifera L. cv. Pinot noir) growth and resulting fruit and wine phenolic composition were investigated. The study was conducted in a commercial vineyard consisting of the same clone, rootstock, age, and vineyard management practices. The experimental design involved monitoring soil, vine growth, yield components, and fruit composition (soluble solids, flavan-3-ol monomers, proanthocyanidins, and pigmented polymers) on a georeferenced grid pattern to assess patterns in growth and development. Vine vigor parameters (trunk cross-sectional area, average shoot length, and leaf chlorophyll) were used to delineate zones within both blocks to produce research wines to investigate the vine-fruit-wine continuum. There was no significant influence of vine vigor on the amount of proanthocyanidin per seed and only minimal differences in seed proanthocyanidin composition. However, significant increases were found in skin proanthocyanidin (mg/berry), proportion of (-)-epigallocatechin, average molecular mass of proanthocyanidins, and pigmented polymer content in fruit from zones with a reduction in vine vigor. In the wines produced from low-vigor zones, there was a large increase in the proportion of skin tannin extracted into the wine, whereas little change occurred in seed proanthocyanidin extraction. The level of pigmented polymers and proanthocyanidin molecular mass were higher in wines made from low-vigor fruit compared to wines made from high-vigor fruit, whereas the flavan-3-ol monomer concentration was lower.

    2014-01-01

    Full Text Available In an increasingly global and highly competitive business world of today, the business sector pays meticulous attention to stakeholders - groups or individuals, which affect or are affected by business decisions. The paper examines the methodology of identifying key stakeholders, demonstrates the process of their various mapping models, as well as the manner in which stakeholders, in cooperation with a corporation, create the opportunity to be engaged at an early stage of a project, activity or business decision, thus establishing a precedent according to which both sides benefit. By doing so, the business sector can ensure that its actions will receive 'a social licence to operate', whereas various groups of stakeholders will be offered a possibility to be included in business dealings for the sake of protecting their interests. The authors of the paper have analysed a two-way process of stakeholder management in establishing corporate reputation which is reflected in business performance and results. It was concluded that stakeholder engagement should foster innovation and lead to broader social prosperity, achieving the main goal of sustainability: business excellence according to the principles of the triple final result, by realizing synergy between the social community, environment and profit.

    Full Text Available Companies’ strategies and values must be in accordance to stakeholders’ expectations and needs because their role and influences on companies’ activity are decisive for companies future development. Corporate Social Responsibility is a meaningful way through which companies can pursue sustainable development by having a coherent economical, social and environmental perspective on how the business should be managed. CSR must become an integral part of corporate management system, because it has a major role in distressing the relation between company and major stakeholders, both internally and externally. CSR is a global phenomenon, which draws the attention of a growing number of partisans, from public private and social sector. To demonstrate the applicability of the theoretical approaches deduced from the existing literature, the authors recourse to an empirical qualitative research, conducted through a questionnaire implemented to top managers, HR managers and heads of CSR departments within large companies that operate in Romania. The research is based on the analysis of a number of 87 questionnaires and aims to highlight major stakeholders and finding how companies’ responsible activities can influence stakeholders. This study is designed to highlight how prioritization of stakeholders influences CSR initiatives within large companies that operate in Romania, and to present a perspective of company’s approach towards shared value influence major stakeholders. The conclusions drawn have a greater relevance both theoretically and especially practically because provides insights on how large companies perceive CSR and how stakeholders influence responsible initiatives in emergent country like Romania where stereotypes are difficult to manage.

    Whereas past wolf management in the United States was restricted to recovery, managers must now contend with publicly contentious post-recovery issues including regulated hunting seasons. Understanding stakeholder concerns associated with hunting can inform stakeholder engagement, communication, and policy development and evaluation. Social identity theory (SIT) has been used to understand how groups interact, why they conflict, and how collaboration may be achieved. Applying SIT to stakeholder conflicts about wolf hunting may help delineate groups according to their concern about, support for or opposition to the policy choice of hunting wolves. Our objective was to assess concerns about hunting as a tool to resolve conflict in Michigan, using SIT as a framework. We used a mixed-modal sampling approach (e.g., paper, Internet) with wolf hunting-related public meeting participants in March 2013. Survey questions focused on 12 concerns previously identified as associated with hunting as a management tool to resolve conflict. Respondents (n  =  666) cared greatly about wolves but were divided over hunting wolves. Wolf conflicts, use of science in policy decisions, and maintaining a wolf population were the highest ranked concerns. Principle components analysis reduced concerns into three factors that explained 50.7% of total variance; concerns crystallized over justifications for hunting. General linear models revealed a lack of geographic influence on care, fear and support for hunting related to wolves. These findings challenge assumptions about regional differences and suggest a strong role for social identity in driving dichotomized public perceptions in wildlife management.

    Health research that includes youth and family stakeholders increases the contextual relevance of findings, which can benefit both the researchers and stakeholders involved. The goal of this study was to identify youth and family adolescent health priorities and to explore strategies to address these concerns. Stakeholders identified important adolescent health concerns, perceptions of which were then explored using concept mapping. Concept mapping is a mixed-method participatory research approach that invites input from various stakeholders. In response to prompts, stakeholders suggested ways to address the identified health conditions. Adolescent participants then sorted the statements into groups based on content similarity and rated the statements for importance and feasibility. Multidimensional scaling and cluster analysis were then applied to create the concept maps. Stakeholders identified sexually transmitted infections (STIs) and obesity as the health conditions they considered most important. The concept map for STIs identified 7 clusters: General sex education, support and empowerment, testing and treatment, community involvement and awareness, prevention and protection, parental involvement in sex education, and media. The obesity concept map portrayed 8 clusters: Healthy food choices, obesity education, support systems, clinical and community involvement, community support for exercise, physical activity, nutrition support, and nutrition education. Ratings were generally higher for importance than for feasibility. The concept maps demonstrate stakeholder-driven ideas about approaches to target STIs and obesity in this context. Strategies at multiple social ecological levels were emphasized. The concept maps can be used to generate discussion regarding these topics and to identify interventions.

    Full Text Available Stakeholder theory is the main-stream way of conceiving organizations, especially for profit corporations. Corporations are described as a web of stakeholders before whom managers have a multi-fiduciary responsibility. Edward Freeman, the father of stakeholder theory, holds that a normative theory of stakeholder management would set those fiduciary responsibilities as truly moral duties, due to the fact that stakeholders possess intrinsic, as opposed to merely instrumental, value. This article criticizes the basis of Freeman’s defense of normative stakeholder theory. The crucial critical argument is that Freeman employs the very same normative foundation that the classic theory of the firm uses; while deriving a view of the corporation that is less precise than the classic one. As an alternative, it is proposed that the organization should be conceived as a realm for justice: a social context of interaction where all parties would find it rational to agree to criteria for distributing the benefits so that cooperation –as required to bring about those benefits– is secured. This approach founds obligations (among stakeholders without the need to resort to hypothesis as individual dignity or rights. However, the demands of justice might still be operationalized as rights of several kinds.

    Full Text Available Green retrofits, which improve the environment and energy efficiency of buildings, are considered a potential solution for reducing energy consumption as well as improving human health and productivity. They represent some of the riskiest, most complex, and most uncertain projects to manage. As the foundation of project management, critical success factors (CSFs have been emphasized by previous research. However, most studies identified and prioritized CSFs independently of stakeholders. This differs from the reality, where the success of green retrofits is tightly interrelated to the stakeholders of projects. To improve the analysis from a stakeholder perspective, the present study proposed an innovative method based on a two-mode social network analysis to integrate CSF analysis with stakeholders. The results of this method can provide further understanding of the interactions between stakeholders and CSFs, and the underlying relationship among CSFs through stakeholders. A pilot study was conducted to apply the proposed method and assess the CSFs for green retrofits in China. The five most significant CSFs are identified in the management of green retrofit. Furthermore, the interrelations between stakeholders and CSFs, coefficient and clusters of CSFs are likewise discussed.

    Use of participatory stakeholder engagement processes could be important to reduce the risk of potential conflicts in managing contaminated sites. Most stakeholder engagement techniques are qualitative in nature and require experienced facilitators. This study proposes a multicriteria involvement process to enhance transparency and stakeholder participation and applies it to a contaminated sediment management case study for Bergen Harbor, Norway. The suggested multicriteria involvement process builds on the quantitative principles of multicriteria decision analysis and also incorporates group interaction and learning through qualitative participatory methods. Three different advisory groups consisting of local residents, local stakeholders, and nonresident sediment experts were invited to participate in a stakeholder engagement process to provide consensual comparative advice on sediment remediation alternatives. In order for stakeholders or residents to be able to embrace a complex decision such as selection of remediation alternatives, the involvement process with lateral learning, combined with multicriteria decision analysis providing structure, robustness and transparent documentation was preferable. In addition, a multicriteria involvement process resulted in consistent ranking of remediation alternatives across residents, stakeholder, and experts, relative to individual intuitive ranking without the multicriteria involvement process.

    Green retrofits, which improve the environment and energy efficiency of buildings, are considered a potential solution for reducing energy consumption as well as improving human health and productivity. They represent some of the riskiest, most complex, and most uncertain projects to manage. As the foundation of project management, critical success factors (CSFs) have been emphasized by previous research. However, most studies identified and prioritized CSFs independently of stakeholders. This differs from the reality, where the success of green retrofits is tightly interrelated to the stakeholders of projects. To improve the analysis from a stakeholder perspective, the present study proposed an innovative method based on a two-mode social network analysis to integrate CSF analysis with stakeholders. The results of this method can provide further understanding of the interactions between stakeholders and CSFs, and the underlying relationship among CSFs through stakeholders. A pilot study was conducted to apply the proposed method and assess the CSFs for green retrofits in China. The five most significant CSFs are identified in the management of green retrofit. Furthermore, the interrelations between stakeholders and CSFs, coefficient and clusters of CSFs are likewise discussed. PMID:26516897

    Although studies have shown health benefits for moderate-intensity physical activity, there is limited evidence to support beneficial effects for high amounts of vigorous activity among middle-age and older men. The objective of this study was to examine the relationship between vigorous-intensity physical activity, compared with moderate-intensity activity, and risk of major chronic disease in men. We prospectively examined the associations between vigorous- and moderate-intensity physical activity and risk of major chronic disease among 44,551 men age 40-75 yr in 1986. Leisure-time physical activity was assessed biennially by questionnaire. During 22 yr of follow-up, we documented 14,162 incident cases of major chronic disease, including 4769 cardiovascular events, 6449 cancer events, and 2944 deaths from other causes. The HR of major chronic disease comparing ≥ 21 to 0 MET.h.wk(-1) of exercise was 0.86 (95% confidence interval (CI), 0.81-0.91) for vigorous-intensity activity and 0.85 (95% CI, 0.80-0.90) for moderate activity. For cardiovascular disease (CVD), the corresponding HRs were 0.78 (95% CI, 0.70-0.86) and 0.80 (95% CI, 0.72-0.88), respectively. When examined separately, running, tennis, and brisk walking were inversely associated with CVD risk. Furthermore, more vigorous activity was associated with lower disease risk; the HR comparing >70 to 0 MET.h.wk(-1) of vigorous-intensity exercise was 0.79 (95% CI, 0.68-0.92; P moderate-intensity physical activities were associated with lower risk of major chronic disease and CVD. Increasing amounts of vigorous activity remained inversely associated with disease risk, even among men in the highest categories of exercise.

    Full Text Available Seed ageing is an important cause of low vigor and bad field emergence, especially in adverse seedbed conditions. Therefore, in this investigation, soybean seed vigor was tested by four laboratory tests (germination energy GE, standard germination SG, cold test CT, electrical conductivity EC and in field trial, as well (early planting dates Epd and optimal planting dates Opd. The soybean seed of 5 cultivars from Agricultural Institute Osijek, produced in the 3 years (1999., 2000., 2001. was used in the investigation. The seed was stored in a warehouse conditions for 6, 18 or 30 months prior to testing. Tested soybean seed showed significant differences in seed vigor influenced by seed age, seed treatment with fungicide (Vitavax 200 FF, cultivar and planting date. High quality seed with GE and SG over 85%,performed quite well in both planting dates, as well as seeds with the CT over 70% or with EC under 42 μScm-1g-1. On the contrary, considering seed with reduced vigor there is a very great possibility of reduced FE especially in Epd. However, seed treatment with fungicide and sowing in optimal seedbed conditions can significantly contribute to improvement of soybean seed performance and stand establishment. Correlation analyses showed that all tested seed vigor parameters were significantly connected (sign. level 99%. At early planting, the strongest correlation was established between the field emergence and CT (untreated seed, r=0.949** and for treated seed r=0.951** whereas in optimal planting date was between the field emergence and SG (for untreated seed r=0. 938** and for treated seed r=0.942**. Laboratory seed health testing showed significant differences in fungal disease intensity influenced by fungicide seed treatment, cultivar and seed age. Total seed infection and infection with Fusarium spp. was adversely correlated with all vigor parameters. All tested vigor parameters of soybean seed had influence on grain yield indirectly by

    Objectives To estimate the associations of moderate and vigorous intensity exercise during pregnancy with the rate of gestational weight gain (GWG) from gestational diabetes (GDM) diagnosis to delivery, overall and stratified by prepregnancy overweight/obesity. Methods Prospective cohort study with physical activity reported shortly after the GDM diagnosis and prepregnancy weight and post-diagnosis GWG obtained from electronic health records (n = 1055). Multinomial logistic regression models in the full cohort and stratified by prepregnancy overweight/obesity estimated associations of moderate and vigorous intensity exercise with GWG below and above the Institute of Medicine's (IOM) prepregnancy BMI-specific recommended ranges for weekly rate of GWG in the second and third trimesters. Results In the full cohort, any participation in vigorous intensity exercise was associated with decreased odds of GWG above recommended ranges as compared to no participation [odds ratio (95 % confidence interval): 0.63 (0.40, 0.99)], with a significant trend for decreasing odds of excess GWG with increasing level of vigorous intensity exercise. Upon stratification by prepregnancy overweight/obesity, significant associations were only observed for BMI ≥ 25.0 kg/m(2): any vigorous intensity exercise, as compared to none, was associated with 54 % decreased odds of excess GWG [0.46 (0.27, 0.79)] and significant trends were detected for decreasing odds of GWG both below and above the IOM's recommended ranges with increasing level of vigorous exercise (both P ≤ 0.03). No associations were observed for moderate intensity exercise. Conclusions for Practice In women with GDM, particularly overweight and obese women, vigorous intensity exercise during pregnancy may reduce the odds of excess GWG.

    Observation systems that collect information on environmental parameters relevant to biological and physical earth resources provide value. This has been demonstrated so many times in so many ways that it is not worth deliberating. Earlier projects for research (whether it is possible to do this or that), or for "dual use," typically involving defense, have been successful. Wealthy parties have built their own systems. Less wealthy parties seek to sustain the systems they have built. The history of systems suggests that "requirements" will be the next step. The objective is to maximize the "return" on the substantial investment required for construction, deployment, maintenance and renewal of observation systems. Stakeholders and their interests are assessed to construct the requirements from which specifications are built. Specifications drive procurement, and procurement produces built systems. Complicated (e.g. space-based) systems have long times between requirements analysis and deployment. It all depends on getting the requirements right, which depends on understanding stakeholders and requirements. And this is where things get complicated. Stakeholders and interests change, sometimes rapidly, as what is possible is altered. It becomes increasingly difficult to achieve stakeholder alignment required for effective management of constituent politics at the heart of any expensive endeavor. This paper presents results from a major study of stakeholder alignment in the Earth Sciences, focused especially on EarthCube.

    Participatory approaches involving stakeholders across the health care system can help enhance the development, implementation and evaluation of health services. These approaches may be particularly useful in planning community pharmacy services and so overcome challenges in their implementation into practice. Conducting a stakeholder analysis is a key first step since it allows relevant stakeholders to be identified, as well as providing planners a better understanding of the complexity of the health care system. The main aim of this study was to conduct a stakeholder analysis to identify those individuals and organizations that could be part of a leading planning group for the development of a community pharmacy service (CPS) to prevent cardiovascular disease (CVD) in Australia. An experienced facilitator conducted a workshop with 8 key informants of the Australian health care system. Two structured activities were undertaken. The first explored current needs and gaps in cardiovascular care and the role of community pharmacists. The second was a stakeholder analysis, using both ex-ante and ad-hoc approaches. Identified stakeholders were then classified into three groups according to their relative influence on the development of the pharmacy service. The information gathered was analyzed using qualitative content analysis. The key informants identified 46 stakeholders, including (1) patient/consumers and their representative organizations, (2) health care providers and their professional organizations and (3) institutions and organizations that do not directly interact with patients but organize and manage the health care system, develop and implement health policies, pay for health care, influence funding for health service research or promote new health initiatives. From the 46 stakeholders, a core group of 12 stakeholders was defined. These were considered crucial to the service's development because they held positions that could drive or inhibit progress

    ABSTRACT OBJECTIVE The objective of this study is to establish cutoff points for the number of steps/day and minutes/day of moderate to vigorous physical activity in relation to the risk of childhood overweight and obesity and their respective associations. In addition, we aim to identify the amount of steps/day needed to achieve the recommendation of moderate to vigorous physical activity in children from São Caetano do Sul. METHODS In total, 494 children have used an accelerometer to monitor steps/day and the intensity of physical activity (min/day). The moderate to vigorous physical activity has been categorized according to the public health recommendation (≤ 60 versus > 60 min/day). Overweight or obesity is defined as body mass index > +1 SD, based on reference data from the World Health Organization. The data on family income, education of parents, screen time, diet pattern, and sedentary time have been collected by questionnaires. Logistic regression and Receiver Operating Characteristic curves have been constructed. RESULTS On average, boys walked more steps/day (1,850) and performed more min/day of moderate to vigorous physical activity (23.1) than girls. Overall, 51.4% of the children have been classified as eutrophic and 48.6% as overweight or obese. Eutrophic boys walked 1,525 steps/day and performed 18.6 minutes/day more of moderate to vigorous physical activity than those with overweight/obesity (p 0.05). The cutoff points to prevent overweight and obesity in boys and girls were 10,500 and 8,500 steps/day and 66 and 46 min/day of moderate to vigorous physical activity, respectively. The walking of 9,700 steps/day for boys and 9,400 steps/day for girls ensures the scope of the recommendation of moderate to vigorous physical activity. CONCLUSIONS In boys, steps/day and moderate to vigorous physical activity have been negatively associated with body mass index, regardless of race, family income, education of parents, screen time, diet pattern, and

    Full Text Available As firms are creating and recreating themselves as stakeholder corporations, tensions mount between a firm’s fiduciary duties to its shareholders and the broader responsibilities inherent in a stakeholder focus. Firms have employed several techniques to help resolve this tension with limited success. We suggest that the next step in reducing this tension is formally accounting for stakeholder value through changes in financial reporting. We contend that stakeholders have a financial value to the firm that can and should be accounted for through the firm’s financial reporting system. We propose a three-step process we call stakeholder valuing (SV to begin a conversation regarding how such a method can be created. SV begins with codifying the firm’s identity as a stakeholder entity, moves to assessing stakeholder value that’s consistent with that identity, and concludes with accounting for and reporting that value. What we are suggesting will be seen by some as a radical change in accounting practices but we believe it is necessary as we move toward a consistent, reliable, verifiable, transparent, and comparable means of accounting for the true value of a stakeholder corporation.

    Sleep is crucial for psychological functioning and daily performance. Both lay and scientific opinion hold that physical activity encourages restorative sleep. However, research on this in adolescence is limited. The aim of the present study was to compare sleep-EEG patterns of vigorous exercisers and controls. Twelve adolescent male football players (14 h of vigorous exercise per week) and 12 controls (1.5 h of vigorous exercise per week) matched for gender, age (about 16 years), and educational level, took part in the study. Sleep-EEG registration was performed following a day without exercise. Sleep-EEG analyses revealed that, compared to controls, the football players showed greater sleep efficiency, shortened sleep onset latency, less awakenings after sleep onset, more stage 4, and less REM sleep. Importantly, this pattern of results emerged following a day without exercise. Moreover, vigorous football players reported better daily performance and displayed less weeknight (Sunday to Thursday) to weekend night (Friday and Saturday nights) variation. Findings suggest that for the football players, vigorous exercise seemed to lead to longer-lasting electrophysiological change in brain activity irrespective of acute bouts of exercise.

    Full Text Available The assessment of seed vigor has many important implications to the seed industry as a basic monitoring of seed physiological potential during different phases of seed production and a support for strategic decisions regarding the selection of high quality seedlots to meet the consumer demand. The potential attributes of seed vigor as a fundamental physiological seed characteristic and its association with field stand establishment and crop productivity has been worldwide recognized from the 1960s onward. This led to the diversification of research approaches involving the synchronization of different physiological characteristics and events that determine the potential for high performance during seed storage and after sowing. The basic objective of vigor testing is to provide a consistent identification of differences in physiological potential among seedlots of commercial value and this represents a more sensitive parameter than the germination test. There are various procedures to assess seed vigor including those that directly or indirectly evaluate seed metabolic state or identify seed tolerance to specific stress(es. At the same time, in more recent years, new knowledge has come from molecular biology, biotechnology, biophysics and seed and seedling imaging analyses; these approaches has been important complements to traditional seed research.. This text has the purpose to emphasize the role of Brazilian research in seed vigor, whose competence is internationally recognized, and to provide an overview of the evolution of knowledge also attempting to highlight events that contributed to the advancement of research on the subject.

    Aerobic fitness, not merely physical activity, is associated with a reduced risk of cardiovascular disease. Vigorous intensity exercise has been shown to increase aerobic fitness more effectively than moderate intensity exercise, suggesting that the former may confer greater cardioprotective benefits. An electronic search of published studies using PubMed was conducted for 2 types of investigations, epidemiologic studies that evaluated the benefits of physical activity of varying intensity levels and clinical trials that trained individuals at different intensities of exercise while controlling for the total energy expenditure. A secondary search was conducted using the references from these studies. The epidemiologic studies consistently found a greater reduction in risk of cardiovascular disease with vigorous (typically > or =6 METs) than with moderate intensity physical activity and reported more favorable risk profiles for individuals engaged in vigorous, as opposed to moderate, intensity physical activity. Clinical trials generally reported greater improvements after vigorous (typically > or =60% aerobic capacity) compared with moderate intensity exercise for diastolic blood pressure, glucose control, and aerobic capacity, but reported no intensity effect on improvements in systolic blood pressure, lipid profile, or body fat loss. In conclusion, if the total energy expenditure of exercise is held constant, exercise performed at a vigorous intensity appears to convey greater cardioprotective benefits than exercise of a moderate intensity.

    To determine (a) the essential components of social participation for preschool children with Autism Spectrum Disorder (ASD) using stakeholders' perspectives and (b) the facilitators and barriers experienced in promoting social participation. A mixed-methods, web-based survey utilizing the International Classification of Functioning, Disability and Health - Child and Youth version (ICF-CY) taxonomy was circulated across Canada through purposeful snowball sampling. Frequency analysis of the combined responses of 74 stakeholders revealed the most essential components of social participation were: (a) behavior management, (b) social interactions, and (c) various types of play. Further, content analysis revealed that stakeholders used intrinsic motivation strategies and contingency management to facilitate social participation. Stakeholders reported that the purpose of social participation was to engage the child in fun, enjoyable social activities that developed relationships between the child and peers and created a sense of belonging in the community.

    Focus group research was used to examine how community stakeholders, a group with local industry experience, responded to coal industry advocacy messages. The stakeholders expressed beliefs about both the advertiser and the coal industry, and while their knowledge led to critical consideration of the industry campaign, they also expressed a desire to identify with positive messages about their community. Applying a postpositivist research perspective, a new model is introduced to integrate these beliefs in terms of advertiser trust and industry accountability under the existing theoretical framework of persuasion knowledge. Agent and topic knowledge are combined in this model based on responses to the industry advocacy campaign. In doing so, this study integrates a priori theory within a new context, extending the current theoretical framework to include an understanding of how community stakeholders - a common target for marketplace advocacy - interpret industry messages.

  12. Coupling Mars' Dust and Water Cycles: Effects on Dust Lifting Vigor, Spatial Extent and Seasonality

    The dust cycle is an important component of Mars' current climate system. Airborne dust affects the radiative balance of the atmosphere, thus greatly influencing the thermal and dynamical state of the atmosphere. Dust raising events on Mars occur at spatial scales ranging from meters to planet-wide. Although the occurrence and season of large regional and global dust storms are highly variable from one year to the next, there are many features of the dust cycle that occur year after year. Generally, a low-level dust haze is maintained during northern spring and summer, while elevated levels of atmospheric dust occur during northern autumn and winter. During years without global-scale dust storms, two peaks in total dust loading were observed by MGS/TES: one peak occurred before northern winter solstice at Ls 200-240, and one peak occurred after northern winter solstice at L(sub s) 305-340. These maxima in dust loading are thought to be associated with transient eddy activity in the northern hemisphere, which has been observed to maximize pre- and post-solstice. Interactive dust cycle studies with Mars General Circulation Models (MGCMs) have included the lifting, transport, and sedimentation of radiatively active dust. Although the predicted global dust loadings from these simulations capture some aspects of the observed dust cycle, there are marked differences between the simulated and observed dust cycles. Most notably, the maximum dust loading is robustly predicted by models to occur near northern winter solstice and is due to dust lifting associated with down slope flows on the flanks of the Hellas basin. Thus far, models have had difficulty simulating the observed pre- and post- solstice peaks in dust loading. Interactive dust cycle studies typically have not included the formation of water ice clouds or their radiative effects. Water ice clouds can influence the dust cycle by scavenging dust from atmosphere and by interacting with solar and infrared radiation

    2017-02-01

    The literature on knowledge translation and dissemination in health care highlights the value of the stakeholder dialogue, namely, a structured process where stakeholders interact to identify the best solution to a given problem. By analyzing the stakeholder dialogue as a form of deliberative argumentation, this article identifies those factors that may hinder or facilitate reaching agreement among stakeholders on options to target problems. Conceptual analysis based on the descriptive and evaluation methods of argumentation theory. When stakeholders have a difference of opinion, confrontation alone does not lead to agreement. A normative model of critical discussion is needed to facilitate stakeholders in reaching this agreement and to prevent barriers to it that can result from personal factors (e.g., attitude and beliefs) or communication moves. This type of dialogue requires a training of stakeholders about the preconditions of argumentation and its different stages. The figure of the moderator is crucial in ensuring that the dialogue fulfills standards of reasonableness. This article offers a reading of the stakeholder dialogue rooted in the tradition of critical thinking. It instructs on how to promote a collaborative exchange among stakeholders as a way to go beyond any expression of views.

    Recent literature on organisational strategy has called for greater emphasis on individuals (stakeholders) and what they do in the process of strategizing. Public sector organisations have to engage with an array of heterogeneous stakeholders in fulfilling their mandate. The public health sector in particular needs to engage with a diversity of stakeholders at local, regional and national levels when strategising. The purpose of this study is to investigate the influence of stakeholder relations on the implementation of Information Systems (IS) strategy in public hospitals in South Africa. An interpretive approach using two provinces was employed. The Activity Analysis and Development (ActAD) framework, an enhanced form of activity theory, was used as the theoretical framework. Data was collected using semi-structured interviews, meetings, documents analysis, physical artefacts and observation. The collected data was analysed using thematic analysis. Findings reveal that IS strategy implementation in public hospitals involves a large and complex network of stakeholder groups at different levels, and over different time periods. These stakeholder groups act in accordance with formal and informal roles, rules and modalities. Various contextual conditions together with the actions of, and interactions between stakeholder groups give rise to the situationality of stakeholder relations dynamics and strategy implementation. The multiple actions and interactions over time lead to the realisation of some aspects of the IS strategy in public hospitals. Given the complexity and dynamism of the context there are also certain unplanned implementations as well. These relationships are captured in a Stakeholder Relations Influence (SRI) framework. The SRI framework can be assistive in the assessment and mapping of stakeholders and stakeholder relations, and the assessment of the implications of these relations for effective IS strategy implementation in public hospitals.

    Stakeholder roles in the application of evidence are influenced by context, the nature of the evidence, the policy development process, and stakeholder interactions. Past research has highlighted the role of stakeholders in knowledge translation (KT) without paying adequate attention to the peculiarities of low-income countries. Here we identify the roles, relations, and interactions among the key stakeholders involved in KT in Uganda and the challenges that they face. This study employed qualitative approaches to examine the roles of and links among various stakeholders in KT. In-depth interviews were conducted with 21 key informants and focused on the key actors in KT, their perceived roles, and challenges. Major stakeholders included civil society organizations with perceived roles of advocacy, community mobilization, and implementation. These stakeholders may ignore unconvincing evidence. The community's role was perceived as advocacy and participation in setting research priorities. The key role of the media was perceived as knowledge dissemination, but respondents noted that the media may misrepresent evidence if it is received in a poorly packaged form. The perceived roles of policy makers were evidence uptake, establishing platforms for KT and stewardship; negative roles included ignoring or even misrepresenting evidence that is not in their favor. The roles of parliamentarians were perceived as advocacy and community mobilization, but they were noted to pursue objectives that may not be supported by the evidence. The researchers' main role was defined as evidence generation, but focusing disproportionately on academic interests was cited as a concern. The donors' main role was defined as funding research and KT, but respondents were concerned about the local relevance of donor-supported research. Respondents reported that links among stakeholders were weak due to the absence of institutionalized, inclusive platforms. Challenges facing the stakeholders in

    Full Text Available In recent years, knowledge, the human capital, and learning organizations have become the key determinants of current global progress. Higher educational sector has been faced with globalization and strong competition. Therefore, the need has arisen for professional management structures and more entrepreneurial style of leadership. Organizations have been transformed to learning organizations by the life long learning concept, while the knowledge management has become the leading tool in building competitive advantages. High education organizations are being pushed forward by competitiveness. That pressure requires continuous improvement emphasizing the need for measuring outcomes and building excellence. The paradigm of stakeholder analysis, applied to specific determinations of the system of higher education institutions, could be a good way for comprehending and predicting interests, needs and requirements of all key players in the environment. The purpose of this paper is to enhance the possibility of understanding the connection between higher education institutions and its environment in context of stakeholder analysis. The paper uses literature as a basis in identifying critical parameters for stakeholder analysis and its implementation to higher education sector. The findings of the paper reveal that the concept of stakeholders is critical and difficult to implement everywhere and to everything. There is a clear attempt of all organizations, especially those that create and encourage knowledge, to understand the actions of all participants and predictions of interests and requirements of the changing environment.

  16. Stakeholder Involvement in Swedish Nuclear Waste Management

    Energy Technology Data Exchange (ETDEWEB)

    Elam, Mark; Sundqvist, Goeran [Goeteborg Univ. (Sweden)

    2006-09-15

    The focus in this paper is on past, current and emerging patterns of stakeholder involvement in the siting of a deep repository for final disposal of Sweden's spent nuclear fuel. In particular, we concentrate on how the two municipalities of Oskarshamn and Oesthammar have acted as engaged stakeholders, and have gained recognition as such, in the siting process. In general: How has stakeholder involvement gained acceptance as an activity of value in the siting of major waste facilities? What are the issues currently subject to stakeholder involvement and how have these been decided upon? An effect of the history of nuclear activity in Oskarshamn and Oesthammar is that stakeholder involvement over a final repository can be divided into social and technical issues. Both municipalities have out of tradition, as part of their social acceptance of a new repository, been prepared to surrender extended involvement in key safety issues. They have been prepared to do this because they also see themselves being able to delegate these safety issues to the government authorities SSI and SKI. These two authorities have been acceptable to the two municipalities as their legitimate 'technological guardians'. As physical geology re-enters the siting process for a deep repository, Oskarshamn appear more prepared to break with tradition than Oesthammar. Oskarshamn are currently demanding transparency from SKB in relation to the exact technical and geological criteria they will use to choose between them and Oesthammar as a repository site. In contrast to Oesthammar, Oskarshamn are preparing with the expected help of SKI and SSI to dispute their geology and its relation to nuclear safety with SKB if they consider it necessary. If Oskarshamn act to draw safety issues in relation to alternative methods and sitings into the EIA process where might this lead? As environmental groups now enter the process (three groups were granted funding in the first round - 2005) the

    We tested the hypothesis that debilitated conidia exhibiting slow-germination (requiring>16h to germinate) are less virulent than vigorous conidia exhibiting fast germination (requiring⩽16h to germinate). Preparations of Beauveria bassiana s.l. strain CG 1027 with variable ratios of vigorous to debilitated conidia were assayed against third-instar larvae of Spodoptera frugiperda. As the proportion of debilitated conidia in test preparations increased, LC50 expressed in terms of total viable conidia increased, while LC50 expressed solely in terms of vigorous conidia remained constant, indicating that vigorous conidia were responsible for nearly all mortality observed in the assays. Larvae treated with conidia from low-quality batches (with high proportions of debilitated conidia) survived consistently longer than those treated with comparable doses of conidia from high-quality batches. These results confirm our previous hypotheses that inclusion of debilitated conidia in viability assessments can lead to overestimation of the quality (potency) of mycoinsecticide preparations and support our recommendation for use of short incubation periods for assessing viability whenever viability is relied upon as an indicator of product quality.

    Full Text Available The financial position of an economic entity is a concept that can have different meanings, depending on the stakeholder category that make its analysis. In energy sector, which is considered of high importance in the national economy, we consider that the most important category of stakeholder is the state (government, because ensuring the functionality of this sector is an crucial condition for development of others sectors from national economy. For this reason, we can look at the informational needs of other stakeholder categories trough the state’s “sine qua non” condition to ensure the optimal functionality of this sector, which manifests itself like this: the functioning of the sector involves the attraction of investors, the functioning of the sector involves the existence of human resources, the functioning of the sector cannot be ensured without the existence of commercial relations that involves suppliers and clients and for insuring the functioning of the sector it is often require various financing sources. All those aspects are giving raise to some categories of stakeholder interested over the parameters in which the energy sector entities are functioning, one of the interest domain being the financial position of the companies activating in its field. Over the present study we had in view to highlight the main present approaches regarding the concept of financial position, but also the main issues fallowed by the main stakeholder categories in their attempt to appreciate the financial position of the entities activating in energy sector which are listed to Bucharest Stock Exchange. The results of this study have showed that there is some base requirements regarding the informational needs of stakeholder regarding the financial position of the companies activating in energy sector, and those are related to the concepts of going concern, overall solvency ratio, general liquidity ratio and indebtedness degree.

    Full Text Available Lower plant transpiration rate (TR under high vapor pressure deficit (VPD conditions and early plant vigor are proposed as major traits influencing the rate of crop water use and possibly the fitness of chickpea lines to specific terminal drought conditions—this being the major constraint limiting chickpea productivity. The physiological mechanisms underlying difference in TR under high VPD and vigor are still unresolved, and so is the link between vigor and TR. Lower TR is hypothesized to relate to hydraulic conductance differences. Experiments were conducted in both soil (Vertisol and hydroponic culture. The assessment of the TR response to increasing VPD showed that high vigor genotypes had TR restriction under high VPD, and this was confirmed in the early vigor parent and progeny genotype (ICC 4958 and RIL 211 having lower TR than the late vigor parent and progeny genotype (ICC 1882 and RIL 022. Inhibition of water transport pathways [apoplast and symplast (aquaporins] in intact plants led to a lower transpiration inhibition in the early vigor/low TR genotypes than in the late vigor/high TR genotypes. De-rooted shoot treatment with an aquaporin inhibitor led to a lower transpiration inhibition in the early vigor/low TR genotypes than in the late vigor/high TR genotypes. Early vigor genotypes had lower root hydraulic conductivity than late vigor/high TR genotypes. Under inhibited conditions (apoplast, symplast, root hydraulic conductivity was reduced more in the late vigor/high TR genotypes than in the early vigor/low TR genotypes. We interpret that early vigor/low TR genotypes have a lower involvement of aquaporins in water transport pathways and may also have a smaller apoplastic pathway than high TR genotypes, which could explain the transpiration restriction under high VPD and would be helpful to conserve soil water under high evaporative demand. These findings open an opportunity for breeding to tailor genotypes with different

    Full Text Available Whereas past wolf management in the United States was restricted to recovery, managers must now contend with publicly contentious post-recovery issues including regulated hunting seasons. Understanding stakeholder concerns associated with hunting can inform stakeholder engagement, communication, and policy development and evaluation. Social identity theory (SIT has been used to understand how groups interact, why they conflict, and how collaboration may be achieved. Applying SIT to stakeholder conflicts about wolf hunting may help delineate groups according to their concern about, support for or opposition to the policy choice of hunting wolves. Our objective was to assess concerns about hunting as a tool to resolve conflict in Michigan, using SIT as a framework. We used a mixed-modal sampling approach (e.g., paper, Internet with wolf hunting-related public meeting participants in March 2013. Survey questions focused on 12 concerns previously identified as associated with hunting as a management tool to resolve conflict. Respondents (n  =  666 cared greatly about wolves but were divided over hunting wolves. Wolf conflicts, use of science in policy decisions, and maintaining a wolf population were the highest ranked concerns. Principle components analysis reduced concerns into three factors that explained 50.7% of total variance; concerns crystallized over justifications for hunting. General linear models revealed a lack of geographic influence on care, fear and support for hunting related to wolves. These findings challenge assumptions about regional differences and suggest a strong role for social identity in driving dichotomized public perceptions in wildlife management.

  16. Better economics: supporting adaptation with stakeholder analysis

    Across the developing world, decision makers understand the need to adapt to climate change — particularly in agriculture, which supports a large proportion of low-income groups who are especially vulnerable to impacts such as increasing water scarcity or more erratic weather. But policymakers are often less clear about what adaptation action to take. Cost-benefit analyses can provide information on the financial feasibility and economic efficiency of a given policy. But such methods fail to capture the non-monetary benefits of adaptation, which can be even more important than the monetary ones. Ongoing work in Morocco shows how combining cost-benefit analysis with a more participatory stakeholder analysis can support effective decision making by identifying cross-sector benefits, highlighting areas of mutual interest among different stakeholders and more effectively assessing impacts on adaptive capacity.

    On April 9--11, 1997, the Department of Energy`s Office of Worker and Community Transition convened its fifth National Stakeholder Workshop. The workshop addressed a wide range of work force restructuring and community transition issues critical to the future success of the Department. Two important elements of the meeting were: (1) reviewing progress made on the challenges identified during the March 1996f stakeholder`s meeting in Atlanta, Georgia; and (2) identifying areas that needed priority attention during the early months of the second Clinton Administration. The format of the Workshop included several plenary sessions and a number of small group discussion sessions. The small group sessions focused on topics related to labor issues, work force restructuring, work force planning, community transition, and employee concerns. The sessions provided a wide range of views on worker and community transition issues. The workshop included presentations on the following topics: Welcome and introductions; Opening remarks; Community reuse organizations: recent accomplishments; Privatization: policy, practice and potential pitfalls; Department of Energy`s integrated training initiatives; Congressional perspective on work force restructuring; and, Privatization and the Ten Year Plan.

    Full Text Available The study analyzes the state of coppice forestry in Bulgaria during last 18 years. Stakeholders and their interests and preferences in coppice forests are explored and assessed. Forests restitution process in Bulgaria started in 1997 and has not been finished yet. Nevertheless, significant further changes of the current ownershipdistribution are not expected. By the end of 2007, the state was the biggest coppice forest owner/stakeholder in Bulgaria with 71.3% of all coppice forests being state property. The other two important stakeholders are the municipalities (14.0% and private owners (12.0%. Currently, forest owners' number in Bulgaria exceeds 1million, the average holding area being smaller than 1 ha. Only 150 individual plots are larger than 50 ha. The majority of private owners aim at taking maximum and immediate profit from their recently restituted forest properties. In most cases that reflects in clearcuts. Coppice forests management has been one of the problematicissues of Bulgarian forestry for decades. Despite of forest authorities significant efforts, the area of coppice forests in Bulgaria (1.78 million ha in 2007 remained unchanged for a period of 50 years. The official forest policy is still aimed at conversionof coppice forests into seed ones through different silvicultural methods. That policy is applied to almost all coppice forests regardless of their ownership.

    Full Text Available Background and Purpose: The office of educational services at universities is a very important division and it is necessary for employees to strive towards providing suitable services to students. The quality of educational services has always been a major concern for higher education managers. Interviewing stakeholders and experts increases our understanding of different aspects of the subject in order to create a native model with high performance capability based on existing conditions and the cultural and political infrastructure of our country. Therefore, we aimed to define the perception and experiences of educational service stakeholders. Methods: In this qualitative thematic content analysis that adapted a deductive approach using Graneheim and Lundman’s method. Initially, purposeful sampling was done to identify and select the students (as first level stakeholders studying paramedical majors at one of the medical science universities of the country during the educational year 2015-2016. Altogether, 20 people were interviewed consisting of 6 students, 4 faculty members, 2 student affairs employees, 1 counselor, 2 education officers, and 2 education office managers.Data were analyzed and coded using MAXQDA software. Results: Of the 400 initial codes extracted through data analysis, 336 abstract codes, 48 sub-categories, 20 categories, and 7 themes were obtained. The level of abstraction was different in the categories. The extracted themes were as follows: information gap before and after entering university, the difference between expected and perceived services and factors contributing to expectations, the university’s approach in enhancing service quality, the student and management of educational problems, the system-student interaction in educational planning, and the professors’ responsibilities and performance in enhancing quality, and the role on the university management system in enhancing the quality of services

    Full Text Available A avaliação do vigor de sementes tem sido ferramenta fundamental dentro do programa de controle de qualidade, sendo o teste de envelhecimento acelerado (EA parte importante do processo. O trabalho foi desenvolvido com o objetivo de confirmar metodologia específica para avaliação do vigor de sementes, em laboratório, tendo como base o EA. Utilizou sementes de milho e soja, seis lotes para cada espécie, com padrões de qualidade (germinação comercialmente aceitas. As condições de envelhecimento préestabelecidas foram 42ºC/96h e 45ºC/72h para milho e 41ºC/48 e 72h e 42ºC/48 e 72h para soja. Para cada combinação de temperatura e período de envelhecimento, as sementes foram colocadas em caixas plásticas, sobre tela, com 40mL de água destilada, distribuídas em camada única e com base no peso das mesmas. O envelhecimento foi feito usando-se dois tipos de câmara, BOD e jaquetada de água (CJ. Foi determinado o teor de água (TA e a germinação das sementes antes e após o EA. A absorção de água pelas sementes considerando-se todas as combinações de período de exposição e temperatura, as duas câmaras e as duas formas de determinação do TA, foi maior quando as sementes foram acondicionadas em camada única em relação aquelas pesadas (massa constante, usando-se a câmara jaquetada. Para o milho, a combinação de 45ºC/72h com o acondicionamento das sementes em camada única foi o método mais eficiente para a separação dos lotes quanto ao vigor. Para soja, a combinação 42ºC/48h foi mais eficiente na separação dos lotes, não havendo interferência do método de acondicionamento das sementes, na tela. Conclui-se que a camada única e a câmara tipo BOD devem ser preferencialmente utilizadas no teste EA face aos menores custos de aquisição e manutenção da BOD, visando à separação de lotes quanto aos níveis de vigor, para milho e soja.The evaluation of the seed vigor has been a fundamental tool of quality

    Nonalcoholic fatty liver disease (NAFLD) is a prevalent risk factor for chronic liver disease and cardiovascular disease. To compare the effects of moderate and vigorous exercise on intrahepatic triglyceride content and metabolic risk factors among patients with NAFLD. In this randomized clinical trial, participants with central obesity and NAFLD were recruited from community-based screening in Xiamen, China, from December 1, 2011, through December 25, 2013. Data analysis was performed from August 28, 2015, through December 15, 2015. Participants were randomly assigned to vigorous-moderate exercise (jogging 150 minutes per week at 65%-80% of maximum heart rate for 6 months and brisk walking 150 minutes per week at 45%-55% of maximum heart rate for another 6 months), moderate exercise (brisk walking 150 minutes per week for 12 months), or no exercise. Primary outcome, change in intrahepatic triglyceride content measured by proton magnetic resonance spectroscopy at 6 and 12 months; secondary outcomes, changes in body weight, waist circumference, body fat, and metabolic risk factors. A total of 220 individuals (mean [SD] age, 53.9 [7.1] years; 149 woman [67.7%]) were randomly assigned to control (n = 74), moderate exercise (n = 73), and vigorous-moderate exercise (n = 73) groups. Of them, 211 (95.9%) completed the 6-month follow-up visit; 208 (94.5%) completed the 12-month follow-up visit. Intrahepatic triglyceride content was reduced by 5.0% (95% CI, -7.2% to 2.8%; P exercise group and 4.2% (95% CI, -6.3% to -2.0%; P exercise group compared with the control group at the 6-month assessment.

Stakeholders were classified as primary, secondary and external. It was found that stakeholder interaction with the structures can be of private, public or cooperative interest. In the analysis there were also identified and mapped the impact of the program on stakeholders and their power to influence the ARs' outcomes. Stakeholders' interactions with the ARs were studied, along with their likely attitudes and behavior towards the man-made structures. Finally, all stakeholder clusters were classified according to their expected degree of involvement throughout the different AR stages. The purpose of this stakeholder analysis was to find out winners and losers connected with the reef deployment. It was found that most stakeholder clusters were affected positively, but also four clusters affected negatively. However, it is believed that those that may be affected negatively do not pose a serious threat to the expected AR development along its lifetime.Nesta análise de intervenientes relativa ao programa de recifes artificiais (RAs localizado na costa do Algarve (Sul de Portugal continental foram identificados 21 grupos de atores distintos.

    Physical inactivity is a leading factor associated with cardiovascular disease and a major contributor to the global burden of disease in developed countries. Subjective mood states associated with acute exercise are likely to influence future exercise adherence and warrant further investigation. The present study examined the effects of a single bout of vigorous exercise on mood and anxiety between individuals with substantially different exercise participation histories. Mood and anxiety were assessed one day before an exercise test (baseline), 5 minutes before (pre-test) and again 10 and 25 minutes post-exercise. Participants were 31 university students (16 males, 15 females; Age M = 20), with 16 participants reporting a history of regular exercise with the remaining 15 reporting to not exercise regularly. Each participant completed an incremental exercise test on a Monark cycle ergometer to volitional exhaustion. Regular exercisers reported significant post-exercise improvements in mood and reductions in state anxiety. By contrast, non-regular exercisers reported an initial decline in post-exercise mood and increased anxiety, followed by an improvement in mood and reduction in anxiety back to pre-exercise levels. Our findings suggest that previous exercise participation mediates affective responses to acute bouts of vigorous exercise. We suggest that to maximise positive mood changes following exercise, practitioners should carefully consider the individual's exercise participation history before prescribing new regimes. Key pointsPrevious exercise participation mediates the affective response to acute bouts of vigorous exercise.Regular exercisers respond positively to acute bouts of vigorous physical activity, reporting less state anxiety and fatigue, and more vigour.Non-regular exercisers respond with an initial reduction in positive mood states, followed by a rebound to baseline levels 25 minutes post-exercise.To maximise positive post-exercise mood states

    In many health care systems, strategies are currently deployed to engage patients and other stakeholders in decisions affecting hospital services. In this paper, a model for stakeholder involvement is presented and evaluated in three Flemish hospitals. In the model, a stakeholder committee advises the hospital's board of directors on themes of strategic importance. To study the internal hospital's decision processes in order to identify the impact of a stakeholder involvement committee on strategic themes in the hospital decision processes. A retrospective analysis of the decision processes was conducted in three hospitals that implemented a stakeholder committee. The analysis consisted of process and outcome evaluation. Fifteen themes were discussed in the stakeholder committees, whereof 11 resulted in a considerable change. None of these were on a strategic level. The theoretical model was not applied as initially developed, but was altered by each hospital. Consequentially, the decision processes differed between the hospitals. Despite alternation of the model, the stakeholder committee showed a meaningful impact in all hospitals on the operational level. As a result of the differences in decision processes, three factors could be identified as facilitators for success: (1) a close interaction with the board of executives, (2) the inclusion of themes with a more practical and patient-oriented nature, and (3) the elaboration of decisions on lower echelons of the organization. To effectively influence the organization's public accountability, hospitals should involve stakeholders in the decision-making process of the organization. The model of a stakeholder committee was not applied as initially developed and did not affect the strategic decision-making processes in the involved hospitals. Results show only impact at the operational level in the participating hospitals. More research is needed connecting stakeholder involvement with hospital governance.

The aim was to investigate the association between the practice of walking, moderate and vigorous physical activities with sociodemographic factors and weight status in freshman students in the first semester of the first year of a public university in Florianopolis/SC. This study assessed198 students (86 men and 112 women. The practice of physical activities was collected with the International Physical Activity Questionnaire – IPAQ, short version. Students of human and educational sciences reported higher amounts of moderate physical activity when compared to health and exact science counterparts (p< 0.05. It was verified that male students, from higher economic status, from the health sciences, and full-time students showed higher time of practice of vigorous physical activity (p< 0.05. Significant associations were also observed between study period and walking, and between gender, scientific field and vigorous physical activity. It was concluded that the variables associated with the practice of physical activity differ according to the type and intensity of physical activity.

    Full Text Available The conservation of Araucaria seeds is widely compromised in function of their recalcitrant feature, which hampers the planning of recovery actions of the degraded populations. Therefore, the objective of this study was to monitor the physiological changes in Araucaria seeds under controlled storage conditions, in order to get insights as to the viability and vigor conservation. The physiological quality of freshly harvested seeds was evaluated and every 60 days throughout the 180 days-storage period in laboratory ambient without thermal control, refrigerator (5 ° C, and freezer (-18 ° C until the final period of 180 days. After each sampling period, the seed viability (germination and tetrazolium tests and vigor (artificial aging, germination speed index – IVG and electrical conductivity were assessed. A reduction in the normal seedlings percentage was noticed over the period of storage of Araucaria seeds. The conservation in freezer and the lack of thermal control caused a complete loss of the seed viability at 60 and 180 days of storage, respectively. However, the refrigerator storage promoted the conservation of seed viability, with 64% germination after 180 days of storage, an event associated with the reduction of the metabolic activity of seeds. Based on the viability and vigor tests, it was concluded that storage in refrigerator provided longer storage periods to Araucaria seeds in comparison to the other storage conditions herein studied.

    Full Text Available Although reward probability is an important factor that shapes animal behavior, it is not well understood however, how the primate brain translates reward expectation into the vigor of movement (reaction time and speed. To address this question, we trained two monkeys in a reaction time task that required wrist movements in response to vibrotactile and visual stimuli, with a variable reward schedule. Correct performance was rewarded in 75 % of the trials. Monkeys were certain that they would be rewarded only in the trials immediately following withheld rewards. In these trials, the animals responded sooner and moved faster. Single-unit recordings from the dorsal striatum revealed that modulations in striatal neurons reflected such modulations of movement vigor. First, in the trials with certain rewards, striatal neurons modulated their firing rates earlier. Second, magnitudes of changes in neuronal firing rates depended on whether or not monkeys were certain about the reward. Third, these modulations depended on the sensory modality of the cue (visual vs. vibratory and/or movement direction (flexions vs. extensions. We conclude that dorsal striatum may be a part of the mechanism responsible for the modulation of movement vigor in response to changes of reward predictability.

    2012-06-01

    Full Text Available The objective of this work was to analyze the germination and seed vigor of two lettuce (Lactuca sativa L. cultivars that were presoaked in biostimulant solutions. The experimental design was a randomized block with four replications in a 2x7 factorial arrangement. Seeds of the cultivars Bariri and Maravilha das Quatro Estações (MQE were presoaked for 16h in solutions of 0, 5, 10, 15, 20, 25 and 30mL.L–1 of a commercial biostimulant. The percentage of germination, germination speed index, seedling length at 7 days after sowing and the ratio between the shoot and radicle of the seedlings were evaluated. The cv. Bariri was significantly superior in all aspects. The use of presoaking seeds in plant growth regulator did not affect the germination, but influenced seedling vigor. Presoaking Bariri in 10mL.L–1 resulted in the highest germination speed index (19.60 while for MQE the best result was obtained after presoaking in 15mL.L–1 (17.75. The results suggest that in favorable conditions presoaking lettuce seeds in biostimulant does not alter the germination, but improves germination speed and seedling vigor, and increases the chances of crop establishment.

    Full Text Available The aim of this study was to determine the sensitivity of the parameters provided by computerized image analysis to detect tomato seed vigor reduction during storage, compared to tests traditionally used for this purpose. Ten lots of tomato seeds, cultivar Mariana, were stored for 12 months in a controlled environment at 20 ± 1 ° C and 45-50% relative humidity. The seed moisture content was monitored and physiological potential assessed at 0, 3, 6 and 12 months after storage, with germination, first count, accelerated aging with saturated salt solution, seedling emergence tests and with computerized image analyzes of seedlings by SVIS® system. A completely random design was used in a 4 x 10 factorial scheme (4 evaluations periods X 10 lots with 4 replications. Data were subjected to analysis of variance and mean comparison by the Scott Knott test at 5% probability. Computer image analysis of tomato seedlings with five days after sowing is able to detect vigor differences between lots and vigor loss during storage.

    To assess the effect and safety of moderate-to-vigorous resistance exercise during pregnancy. Randomized controlled study. Two antenatal clinics in Gothenburg, Sweden. Ninety-two healthy pregnant women. The intervention was administered during gestational weeks 14-25. The intervention group received supervised resistance exercise twice a week, performed at an activity level equivalent to within moderate-to-vigorous (n = 51). The control group received generalized exercise recommendation, a home-based training program and a telephone follow up (n = 41). Health-related quality of life, physical strength, pain, weight, blood pressure, functional status, activity level, and perinatal data. Functional status deteriorated during the intervention in both groups and pain increased. Significant differences between the groups were obtained only for birthweight. Newborns delivered by women who underwent resistance exercise during pregnancy were significantly heavier than those born to control women; 3561 (±452) g vs. 3251 (±437) g (p = 0.02), a difference that disappeared when adjustment was made for gestational age (p = 0.059). Both groups showed normal health-related quality of life, blood pressure, and perinatal data. These findings indicate that supervised, moderate-to-vigorous resistance exercise does not jeopardize the health status of healthy pregnant women or the fetus during pregnancy, but instead appears to be an appropriate form of exercise in healthy pregnancy. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

    Engaging stakeholders from varied organizational levels is essential to successful healthcare quality improvement. However, engagement has been hard to achieve and to measure across diverse stakeholders. Further, current implementation science models provide little clarity about what engagement means, despite its importance. The aim of this study was to understand how stakeholders of healthcare improvement initiatives defined engagement. Participants (n = 86) in this qualitative thematic study were purposively sampled for individual interviews. Participants included leaders, core members, frontline clinicians, support personnel, and other stakeholders of Strategic Clinical Networks in Alberta Health Services, a Canadian provincial health system with over 108,000 employees. We used an iterative thematic approach to analyze participants' responses to the question, "How do you define engagement?" Regardless of their organizational role, participants defined engagement through three interrelated themes. First, engagement was active participation from willing and committed stakeholders, with levels that ranged from information sharing to full decision-making. Second, engagement centered on a shared decision-making process about meaningful change for everyone "around the table," those who are most impacted. Third, engagement was two-way interactions that began early in the change process, where exchanges were respectful and all stakeholders felt heard and understood. This study highlights the commonalities of how stakeholders in a large healthcare system defined engagement-a shared understanding and terminology-to guide and improve stakeholder engagement. Overall, engagement was an active and committed decision-making about a meaningful problem through respectful interactions and dialog where everyone's voice is considered. Our results may be used in conjunction with current implementation models to provide clarity about what engagement means and how to engage various

    2012-01-01

    Modern workplace health promotion (WHP) requires collaboration, partnerships, and alliances with both internal and external stakeholders. However, the identification of the key stakeholders as well as the systematic mapping of their views has barely been covered in the existing research literature. This article describes the stakeholders and stakeholder positions in WHP in Finland. In this study, the stakeholders were classified as internal, interface, and external stakeholders. Furthermore, based on the authors' research, stakeholders and their positions were represented on a stakeholder map as well as by the power-interest matrix of the stakeholders. The governmental authorities play a key role in driving the strategic change toward WHP by preparing the required legislation and regulatory measures. However, both active employers and active employees can through their own work accelerate the development of new WHP services. Close collaboration between employers and employees is required at the individual workplaces. Some stakeholders, such as pension funds and occupational health services (OHS) providers, can act as important driving forces and support the strategic implementation of WHP in the workplaces. However, alone they have only limited opportunities to organize the WHP activities. Understanding the various stakeholders and the systematic mapping of their positions is essential for the successful planning and implementation of WHP activities.

    The relationships between grapevine (Vitis vinifera) vigor variation and resulting fruit anthocyanin accumulation and composition were investigated. The study was conducted in a commercial vineyard consisting of the same clone, rootstock, age, and vineyard management practices. The experimental design involved assigning vigor zones in two vineyard sites based upon differences in vine growth. Fruits and wines were analyzed by HPLC from designated vigor zones in 2003 and 2004. Average berry weight (grams), average dry skin weight (milligrams), degrees Brix, and pH were higher and titratable acidity (grams per liter) was lower in 2003 compared to 2004. In 2003, only the highest and lowest vigor zones had differences in berry weight, whereas there were no differences in 2004. In both years, high vigor zones had lower degrees Brix and higher titratable acidity (milligrams per liter). Accumulation of anthocyanins (milligrams per berry) was greater in 2003 compared to 2004. There was a trend for lower anthocyanin concentration (milligrams per berry) in high vigor zones in both years. In 2004 compared to 2003, there was a higher proportion of malvidin-3-O-glucoside and lower proportions of the other four anthocyanins (delphinidin-, cyanidin-, petunidin-, and peonidin-3-O-glucosides) found in Pinot Noir. In both years, site A had proportionally higher peonidin-3-O-glucoside and lower malvidin-3-O-glucoside than site B. Some of these differences may be related to the higher exposure and temperatures found in site B compared to site A and also in the low vigor zones.

  16. QTLs for seed vigor-related traits identified in maize seeds germinated under artificial aging conditions.

    Zanping Han

    Full Text Available High seed vigor is important for agricultural production due to the associated potential for increased growth and productivity. However, a better understanding of the underlying molecular mechanisms is required because the genetic basis for seed vigor remains unknown. We used single-nucleotide polymorphism (SNP markers to map quantitative trait loci (QTLs for four seed vigor traits in two connected recombinant inbred line (RIL maize populations under four treatment conditions during seed germination. Sixty-five QTLs distributed between the two populations were identified and a meta-analysis was used to integrate genetic maps. Sixty-one initially identified QTLs were integrated into 18 meta-QTLs (mQTLs. Initial QTLs with contribution to phenotypic variation values of R(2>10% were integrated into mQTLs. Twenty-three candidate genes for association with seed vigor traits coincided with 13 mQTLs. The candidate genes had functions in the glycolytic pathway and in protein metabolism. QTLs with major effects (R(2>10% were identified under at least one treatment condition for mQTL2, mQTL3-2, and mQTL3-4. Candidate genes included a calcium-dependent protein kinase gene (302810918 involved in signal transduction that mapped in the mQTL3-2 interval associated with germination energy (GE and germination percentage (GP, and an hsp20/alpha crystallin family protein gene (At5g51440 that mapped in the mQTL3-4 interval associated with GE and GP. Two initial QTLs with a major effect under at least two treatment conditions were identified for mQTL5-2. A cucumisin-like Ser protease gene (At5g67360 mapped in the mQTL5-2 interval associated with GP. The chromosome regions for mQTL2, mQTL3-2, mQTL3-4, and mQTL5-2 may be hot spots for QTLs related to seed vigor traits. The mQTLs and candidate genes identified in this study provide valuable information for the identification of additional quantitative trait genes.

Semi-structured expert interviews were conducted with 21 participants in the capital, Phnom Penh. The sample included participants involved in providing reproductive health services through international and local health agencies and the pharmaceutical industry. A theme of controversy over the role of misoprostol in the context of reproductive health services emerged, along with a need to reconcile legitimate viewpoints in order to understand the place of misoprostol in the Cambodian reproductive health setting. Understanding stakeholder perspectives on misoprostol can shed light on the drug's role in reproductive health programming where maternal mortality is high and health facilities are still improving.

    Full Text Available Consistent with the extant management literature, mission statements are crucial for the sustainability and growth of any firms and have been considered to be a tool for the strategic management process. Despite the considerable attention awarded to this theme, the role of the mission statement in the strategic management of tourism firms has not been sufficiently highlighted. The present paper tries to bridge this literature gap and aims to (i analyze the content of mission statements; and (ii investigate the stakeholder orientation of cruise line mission statements. We apply a content analysis method to analyze the mission statements of 44 cruise lines, employing three different perspectives: (1 the inclusion of stakeholder groups; (2 mentions of specific “mission” components; (3 reference to four goals usually assigned to mission statements. The analysis was performed using the software package QDA-Miner. The results suggest that it is possible to identify four clusters of firms that present similar content in their mission statements, and that cruise companies tend to reserve a major attention to customers. This contribution presents some valuable research implications mainly useful for researchers and academics, but also maybe of benefit to professionals and investors.

    Full Text Available In every life cycle of the project there are numerous people or organizations involved either directly or indirectly. While these type of people and organizations involved are called stakeholders and these may include the project team, client or customer, community, environment, suppliers, government. Stakeholders contribute and share their experiences, knowledge, and insights to support the project throughout its life cycle and therefore it is crucial to capture their input. However, before initiation of the project, stakeholders need to be identified. Following the fact that there are strategies and processes for stakeholder identification, it is not clear what skills are needed to employ those strategies for stakeholder identification. These skills are exceedingly important to have because in today's corporate world, the project team must be flexible in every aspect of their job and be able to complement their skills for the success of stakeholder identification. Using literature review, this paper seeks to describe the skills of project leader needed to identify the project team and the external stakeholders. Inductive approach was followed in this study and data was collected qualitatively using secondary sources. There are two essential skills i.e. relationship building skills and communication skills for internal stakeholders and four major skills i.e. communication skills, people skills, intellectual skills and conceptual skills for external stakeholders are identified for the identification of project stakeholders through literature review considering the sustainability issues in the project management.

    2013-07-01

    This paper analyses the potential for the involvement of different types of stakeholders in the Implementing Geological Disposal Technology Platform (IGD-TP). This analysis was conducted as part of the InSOTEC project, a three-year (2011- 2014) collaborative research project funded under the 7. Euratom Framework Programme (Grant Agreement nr. 269906). In our analysis, we consider the extent to which the IGDTP's practice as regards to stakeholder involvement matches its discourse, and what potential for improvement exists given its structural organisation as a European Technology Platform (ETPs). Technology Platforms (TPs) can be understood as knowledge networks, deliberately set up to influence (research) policy in a specific domain. We therefore use knowledge networks as a conceptual approach and look at the IGD-TP as a complex network which includes actors, knowledge and practices across different countries, focusing on a very specific topic (i.e. implementing geological disposal). We compare the way different stakeholders are involved in the IGD-TP to the practice of other ETPs, and explore how the IGD-TP is viewed by its members and by outsiders to the platform Applying Callon's framework of knowledge co-production (1999) we come to define different degrees of interaction between science, society and policy in view of defining research and development (R and D) priorities [1]. Subsequently we describe how these interactions could be conceptualised and interpreted for the IGD-TP. The current approach of the IGDTP can be mainly understood as classical model involving mainly expert stakeholders and scientists. Where there seems to be a good representation among IGD-TP members of industry, research institutes, and some members of the academic community this is not the case for other types of stakeholders, such as public authorities or civil society. At this stage, the overall approach of the IGD-TP would seem to restrict the scope of stakeholder

    Full Text Available Information Communication Technology (ICT researchers adapt and use tools from reference and cognate disciplines. This application of existing tools outside the context of their development has implications beyond the immediate problem context. ICT researchers have access to a wide variety of data sources including newer ones, such as the Internet, that may bring unexpected outcomes. ICT research can impact on researchers, their institutions and the researched in unexpected ways. People so affected are the stakeholders in ICT research activities. Reputations, welfare and property may be put at risk by unplanned events described in this paper. Legal aspects of ICT research are broadly identified and linked to the tort of negligence. The Social Research Association’s Code for researcher safety is described and its application extended to include the Internet as a potential data source. A common set of underlying ethical principles is identified suggesting that the ICT researcher can refine particular research protocols for specific social contexts.

    Full Text Available Brassica oleracea var italica occupies a special place in the internal and external market of vegetables seeds. Vegetables producers demand seeds with high degree of purity, germination and vigor, since seeds' quality is the basis for the success of the production. In this work, broccoli seeds were coated in a spouted bed, by an aqueous suspension of hidroxy-ethyl-cellulose. Effects of the operating variables: spouting air temperature, atomizing air pressure and coating suspension flow rate over the dependent variables: seeds germination, seeds accelerated aging and the speed of seeds germination in soil, were investigated in a factorial scheme trial. The maximum processing time was 120 min. A totally randomized experiment evaluated and compared seeds germination and vigor of the coated and non-coated seeds. There was no identifiable, pronounced difference on germination of coated and non-coated seeds, accelerated aging of seeds, and speed of seeds germination in the soil. Coating with hidroxy-ethyl-cellulose in the spouted bed did not alter broccoli seeds physiologic quality. The surface of coated seeds presented satisfactory distribution and spreading of the polymer film, uniform and individual coating and homogeneous aspect.Dentre as sementes de hortaliças comercializadas no mercado interno e externo, a Brassica oleracea var. itálica ocupa lugar de destaque.

CO2 concentration was quantified in samples submitted to five periods of incubation at 40° C with the aid of a gas exchange analyzer coupled to an injection and airflow system. The results were subjected to analysis of variance and the mean values were compared by the Duncan test and by regression analysis at the 5% level of significance. B. napus seeds from all lots showed a high percentage of normal plantlets and germination rate index. Percentage of normal plantlets was correlated with CO2 concentration. Determination of the CO2 concentration was more efficient with three hours of incubation which allowed classification of canola seed lots into four vigor classes. CO2 concentration was inversely proportional to the percentage of normal plantlets.A semente marca o inicio da produção de grãos de plantas cultivadas.

    Raffinose family oligosaccharides (RFOs) accumulate in seeds during maturation desiccation in many plant species. However, it remains unclear whether RFOs have a role in establishing seed vigor. GALACTINOL SYNTHASE (GOLS), RAFFINOSE SYNTHASE (RS), and STACHYOSE SYNTHASE (STS) are the enzymes responsible for RFO biosynthesis in plants. Interestingly, only raffinose is detected in maize seeds, and a unique maize RS gene (ZmRS) was identified. In this study, we found that two independent mutator (Mu)-interrupted zmrs lines, containing no raffinose but hyperaccumulating galactinol, have significantly reduced seed vigor, compared with null segregant controls. Unlike maize, Arabidopsis thaliana seeds contain several RFOs (raffinose, stachyose, and verbascose). Manipulation of A. thaliana RFO content by overexpressing ZmGOLS2, ZmRS, or AtSTS demonstrated that co-overexpression of ZmGOLS2 and ZmRS, or overexpression of ZmGOLS2 alone, significantly increased the total content of RFOs and enhanced Arabidopsis seed vigor. Surprisingly, while overexpression of ZmRS increased seed raffinose content, its overexpression dramatically decreased seed vigor and reduced the seed amounts of galactinol, stachyose, and verbascose. In contrast, the atrs5 mutant seeds are similar to those of the wild type with regard to seed vigor and RFO content, except for stachyose, which accumulated in atrs5 seeds. Total RFOs, RFO/sucrose ratio, but not absolute individual RFO amounts, positively correlated with A. thaliana seed vigor, to which stachyose and verbascose contribute more than raffinose. Taken together, these results provide new insights into regulatory mechanisms of seed vigor and reveal distinct requirement for RFOs in modulating seed vigor in a monocot and a dicot.

    Full Text Available The paper analyses the perceptions of the stakeholders regarding the key issues in Power Purchase Agreements (PPAs in the Nepalese Environment. A total of 90 questionnaires representing sponsors, utility, lenders and government officials were used for the study. The questionnaire sought the perception of the stakeholders regarding the significance (importance of the clauses and the likelihood of inclusion of the clauses in PPAs. Comparison of the ranks of means was conducted by Kruskal-Wallis tests to see the significance of the differences in responses of the stakeholders and Mann-Whitney tests to see the significance of the differences of the pairs of stakeholders. Data analysis showed clauses where the prime stakeholders have similar stand and clauses where the perceptions are divergent. The findings of this paper will help the stakeholders in negotiating PPAs.

    Full Text Available The relationship between psychological empowerment of stakeholders and project success is an important thing that must be known by project manager. This research developed and tested the model to predict how well the impact of stakeholder psychological empowerment on project success. Stakeholder psychological empowerment was defined to have five indicator variables covering intrinsic motivation, opportunity to perform, ability to perform, task behaviors, and contextual behaviors. Meanwhile, project success can be measured by cost performance, time performance, quality performance, profitability, and customer satisfaction. In this study, it was hypothesized that stakeholder psychological empowerment influenced project success. Based on the data obtained from a questionnaire survey carried out to 204 respondents, structural equation modeling (SEM was used for predicting the performance of project success. It was found that stakeholder psychological empowerment influenced project success, especially on the ability to perform of stakeholders.

    Sleep is the most important period for recovery from daily load. Regular physical activity enhances overall sleep quality, but the effects of acute exercise on sleep are not well defined. In sleep hygiene recommendations, intensive exercising is not suggested within the last 3 h before bed time, but this recommendation has not been adequately tested experimentally. Therefore, the effects of vigorous late-night exercise on sleep were examined by measuring polysomnographic, actigraphic and subjective sleep quality, as well as cardiac autonomic activity. Eleven (seven men, four women) physically fit young adults (VO(2max) 54±8 mL·kg(-1)·min(-1) , age 26±3 years) were monitored in a sleep laboratory twice in a counterbalanced order: (1) after vigorous late-night exercise; and (2) after a control day without exercise. The incremental cycle ergometer exercise until voluntary exhaustion started at 21:00±00:28 hours, lasted for 35±3 min, and ended 2:13±00:19 hours before bed time. The proportion of non-rapid eye movement sleep was greater after the exercise day than the control day (Psleep quality. During the whole sleep, no differences were found in heart rate (HR) variability, whereas HR was higher after the exercise day than the control day (54±7 versus 51±7, Psleeping hours. The results indicate that vigorous late-night exercise does not disturb sleep quality. However, it may have effects on cardiac autonomic control of heart during the first sleeping hours. © 2010 European Sleep Research Society.

    In 2013, the University of Washington (UW) and Oregon State University began a three-year project to evaluate climate change impacts in the Columbia River Basin (CRB) in the North American Pacific Northwest. The project was funded and coordinated by the River Management Joint Operating Committee (RMJOC), consisting of the Bonneville Power Administration (BPA), US Army Corps of Engineers (USACE), and US Bureau of Reclamation (USBR) and included a host of stakeholders in the region. The team worked to foster communication and collaboration throughout the production process, and also discovered effective collaborative strategies along the way. Project status updates occurred through a variety of outlets, ranging from monthly team check-ins to bi-annual workshops for a much larger audience. The workshops were used to solicit ongoing and timely feedback from a variety of stakeholders including RMJOC members, fish habitat advocates, tribal representatives and public utilities. To further facilitate collaboration, the team restructured the original project timeline, opting for delivering a provisional dataset nine months before the scheduled delivery of the final dataset. This allowed for a previously unplanned series of reviews from stakeholders in the region, who contributed their own expertise and interests to the dataset. The restructuring also encouraged the development of a streamlined infrastructure for performing the actual model simulation, resulting in two benefits: (1) reproducibility, an oft-touted goal within the scientific community, and (2) the ability to incorporate improvements from both stakeholders and scientists at a late stage in the project. We will highlight some of the key scientist-stakeholder engagement interactions throughout the project. We will show that active co-production resulted in a product more useful for not only stakeholders in the region, but also the scientific community.

  15. Inside the volcanic boiler room: knowledge exchange among stakeholders of volcanic unrest

    The knowledge of the causative links between subsurface processes, resulting monitoring signals and imminent eruption is incomplete. As a consequence, hazard assessment and risk mitigation strategies are subject to uncertainty. Discussion of unrest and pre-eruptive scenarios with uncertain outcomes are central during the discourse between a variety of stakeholders in volcanic unrest including scientists, emergency managers, policy makers and the public. Drawing from research within the EC FP7 VUELCO project, we argue that knowledge exchange amongst the different stakeholders of volcanic unrest evolves along three dimensions: 1) the identification of knowledge holders (including local communities) and their needs and expectations, 2) vehicles of communication and 3) trust. In preparing products that feed into risk assessment and management, scientists need to ensure that their deliverables are timely, accurate, clear, understandable and cater to the expectations of emergency managers. The means and content of communication amongst stakeholders need to be defined and adhered to. Finally, efficient and effective interaction between stakeholders is ideally based on mutual trust between those that generate knowledge and those that receive knowledge. For scientists, this entails contextualising volcanic hazard and risk in the framework of environmental and social values. Periods of volcanic quiescence are ideally suited to test established protocols of engagement between stakeholders in preparation for crises situations. The different roles of stakeholders and associated rules of engagement can be scrutinised and reviewed in antecessum rather than ad-hoc during a crisis situation to avoid issues related to distrust, loss of credibility and overall poor risk management. We will discuss these themes drawing from exploitation of research results from Mexico and Ecuador.

    We used a longitudinal design to investigate the hypotheses that the components of the Job Demands-Control-Support model and changes in their levels over time predict subsequent changes in levels of positive affect of vigor over time, and vice versa. Our study was conducted on a sample of adults working in a variety of occupations (N = 909, 68% men) at three points in time (T1, T2, and T3), over a period of about four years, controlling for neuroticism and other potential confounding variables. Job control at T1 and increase in its levels from T1 to T2 predicted an increase from T2 to T3 in the levels of vigor, whereas for social support, only its level at T1 predicted an increase from T2 to T3 in levels of vigor. An increase from T1 to T2 in levels of job demands predicted an increase from T2 to T3 in levels of vigor only for those rated low on neuroticism. Vigor at T1 predicted an increase from T2 to T3 in levels of job control and social support, but not changes from T2 to T3 in levels of job demands. The reciprocal causal relationship between job resources and vigor exists regardless of the demands of the work environment. © 2012 The Authors.

    The objective of this study is to establish cutoff points for the number of steps/day and minutes/day of moderate to vigorous physical activity in relation to the risk of childhood overweight and obesity and their respective associations. In addition, we aim to identify the amount of steps/day needed to achieve the recommendation of moderate to vigorous physical activity in children from São Caetano do Sul. In total, 494 children have used an accelerometer to monitor steps/day and the intensity of physical activity (min/day). The moderate to vigorous physical activity has been categorized according to the public health recommendation (≤ 60 versus > 60 min/day). Overweight or obesity is defined as body mass index > +1 SD, based on reference data from the World Health Organization. The data on family income, education of parents, screen time, diet pattern, and sedentary time have been collected by questionnaires. Logistic regression and Receiver Operating Characteristic curves have been constructed. On average, boys walked more steps/day (1,850) and performed more min/day of moderate to vigorous physical activity (23.1) than girls. Overall, 51.4% of the children have been classified as eutrophic and 48.6% as overweight or obese. Eutrophic boys walked 1,525 steps/day and performed 18.6 minutes/day more of moderate to vigorous physical activity than those with overweight/obesity (p 0.05). The cutoff points to prevent overweight and obesity in boys and girls were 10,500 and 8,500 steps/day and 66 and 46 min/day of moderate to vigorous physical activity, respectively. The walking of 9,700 steps/day for boys and 9,400 steps/day for girls ensures the scope of the recommendation of moderate to vigorous physical activity. In boys, steps/day and moderate to vigorous physical activity have been negatively associated with body mass index, regardless of race, family income, education of parents, screen time, diet pattern, and sedentary time. We suggest, for steps/day and

    Studies on the effects of regular (three to five times per week) periods of moderate to vigorous physical activity (MVPA) on the health, academic performance, attitudes and classroom behaviour of children at school are reviewed. Conclusions from the literature provide a basis for enhancement of school-based physical education programs that are currently considered to lack sufficient intensity, duration and frequency to benefit the children involved. The review not only confirms the value of and need for inclusion of MVPA in physical education programs but also shows the feasibility of doing so, to the advantage of both students and teachers.

Foram coletadas folhas completas no pleno florescimento e na mudança da cor das bagas para análise dos teores totais de N, P, K, Ca e Mg. Determinaram-se o comprimento dos ramos e de seus entrenós, a massa dos ramos podados e calculou-se o índice de Ravaz. Na colheita, foram determinados o comprimento, largura e massa de cachos, a produção de uva por planta e a massa de 100 bagas. As videiras consorciadas com espécies de plantas de cobertura anuais apresentaram maior teor de N total nas folhas na floração, maior vigor e produção de uva. O manejo das plantas de cobertura, mediante transferência dos resíduos culturais da linha de videiras para a entrelinha, não afetou o vigor da videira nem a produção de uva, mas diminuiu o teor total de N nas folhas, na fase da floração. O cultivo da festuca como cobertura do solo do vinhedo pode ser uma alternativa eficaz para se diminuir o vigor da videira.

    Full Text Available A duplicate of this original article was erroneously published in issue six of this year. Please use this original for citation. Universities have to face many changes in the sector of higher education caused by the current dynamic development in this sector. With the decline in state support, increased competition and unfavourable demographic progress, universities are forced to establish and improve their relationships with new and existing stakeholders. Research on relationships among universities and stakeholders has historically focused on the different factors and their influence on improving stakeholder satisfaction with the quality of university services and on strengthening cooperation. Some studies are focused on stakeholders’ classification according to their importance for higher education institutions. However, there are fewer scientific studies which concentrate on the intricacies of managing stakeholder satisfaction according to key areas of Universities. This study aims to design a conceptual scheme for managing stakeholder satisfaction depending on the importance of stakeholders in the key fields of Universities. The research was done in three steps. As the first stage, university stakeholders were identified via interview. In the second stage, the following key fields relating to university activities were identified via focus group - education, science and research, premises and technology. In the third stage, the importance of the particular stakeholders was identified for the fields mentioned in the stage two. In order to gain the necessary information, a set interview method was chosen. Native students were identified as the most important stakeholder for the field - education, academic staff as the most important for the field - research and development and enterprises as the most important stakeholder for the field - premises and equipment. The results of the research conducted provided the authors with a convenient base

    In literature, there is evidence that all stakeholders need to be involved in the curricula building process to make sure that health professionals are "educated" to meet the stakeholders' "demands". In Italy, the involvement of stakeholders in the definition of university curricula is ratified by various regulations. To describe the major experiences of stakeholder involvement in nursing education, identify the main stakeholders for nursing education, and the processes in which they are involved. The search strategy included an electronic exploration of the relevant databases. The search terms were: Stakeholders, Curriculum, Nursing Education combined with Boolean operators. The references of the retrieved articles were hand searched for additional related studies. Most of the studies identified were from the United Kingdom, Australia, and the USA. In Italy, no relevant studies were found. The most frequently identified stakeholders were: students, clinicians, educators, nurse managers. They were mainly involved during profound changes in the curricula and the implementation of new educational approaches. Stakeholders are mostly involved in countries with a private funding system for universities. Such funding systems have probably developed in the academia a greater propensity to involve stakeholders, to provide recognition of success when starting new programs, and are perceived more as marketing research. This seems contrary to the spirit of the Italian and European regulatory interventions, which instead, provide a structured commitment to consolidating and expanding the collaboration among universities, users, and the world of labor. This latter collaboration should facilitate internship activities, lifelong learning, and employability of the newly-graduated professionals.

    Full Text Available Although companies have always been engaged in communicating strategically with the main stakeholders, recent developments have shown that the corporate communication function has been redefined as a complex activity of communicating with both internal and external stakeholders. The authors use stakeholder theory to provide insight into CSR on-line communication by analyzing the content available to the general public of three major Romanian companies. The analysis shows that Romanian companies have adopted mainly the engagement rhetoric, one of the explanations being the fact that many domestic stakeholders still fail to understand the key role of CSR in developing corporate identity and reputation via on-line communication.

    In this study, systems engineering techniques are applied to wave energy to identify and specify stakeholders' requirements for a commercially successful wave energy farm. The focus is on the continental scale utility market. Lifecycle stages and stakeholders are identified. Stakeholders' needs across the whole lifecycle of the wave energy farm are analyzed. A list of 33 stakeholder requirements are identified and specified. This list of requirements should serve as components of a technology performance level metric that could be used by investors and funding agencies to make informed decisions when allocating resources. It is hoped that the technology performance level metric will accelerate wave energy conversion technology convergence.

  9. Engaging stakeholders for adaptive management using structured decision analysis

    Irwin, Elise R.; Kathryn, D.; Kennedy, Mickett

    2009-01-01

    Adaptive management is different from other types of management in that it includes all stakeholders (versus only policy makers) in the process, uses resource optimization techniques to evaluate competing objectives, and recognizes and attempts to reduce uncertainty inherent in natural resource systems. Management actions are negotiated by stakeholders, monitored results are compared to predictions of how the system should respond, and management strategies are adjusted in a “monitor-compare-adjust” iterative routine. Many adaptive management projects fail because of the lack of stakeholder identification, engagement, and continued involvement. Primary reasons for this vary but are usually related to either stakeholders not having ownership (or representation) in decision processes or disenfranchisement of stakeholders after adaptive management begins. We present an example in which stakeholders participated fully in adaptive management of a southeastern regulated river. Structured decision analysis was used to define management objectives and stakeholder values and to determine initial flow prescriptions. The process was transparent, and the visual nature of the modeling software allowed stakeholders to see how their interests and values were represented in the decision process. The development of a stakeholder governance structure and communication mechanism has been critical to the success of the project.

    Many attempts to implement resource management initiatives in Canadian and international communities have been resisted by stakeholders despite inclusion of their representatives in the decision-making process. Managers' failure to understand stakeholders' perspectives when proposing initiatives is a potential cause of this resistance. Our study uses marketing thought to enhance stakeholder theory by bringing in an audience-centric perspective. We attempt to understand how stakeholders perceive their interests in an organization and consequently decide how to influence that organization. By doing so, we investigate whether a disconnect exists between the perceptions of managers and those of stakeholders. Natural resource managers can utilize this knowledge to garner stakeholder support for the organization and its activities. We support this claim with findings from a water transfer plebiscite held in the Canadian province of Alberta. Sixteen personal interviews employing narrative inquiry were conducted to document voters' (i.e., irrigators') interpretations. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Background Endocannabinoids and temperament traits have been linked to both physical activity and body mass index (BMI) however no study has explored how these factors interact in females. The aims of this cross-sectional study were to 1) examine differences among distinct BMI groups on daytime physical activity and time spent in moderate-vigorous physical activity (MVPA), temperament traits and plasma endocannabinoid concentrations; and 2) explore the association and interaction between MVPA, temperament, endocannabinoids and BMI. Methods Physical activity was measured with the wrist-worn accelerometer Actiwatch AW7, in a sample of 189 female participants (43 morbid obese, 30 obese, and 116 healthy-weight controls). The Temperament and Character Inventory-Revised questionnaire was used to assess personality traits. BMI was calculated by bioelectrical impedance analysis via the TANITA digital scale. Blood analyses were conducted to measure levels of endocannabinoids and endocannabinoid-related compounds. Path-analysis was performed to examine the association between predictive variables and MVPA. Results Obese groups showed lower MVPA and dysfunctional temperament traits compared to healthy-weight controls. Plasma concentrations of 2-arachidonoylglyceryl (2-AG) were greater in obese groups. Path-analysis identified a direct effect between greater MVPA and low BMI (b = −0.13, p = .039) and high MVPA levels were associated with elevated anandamide (AEA) levels (b = 0.16, p = .049) and N-oleylethanolamide (OEA) levels (b = 0.22, p = .004), as well as high Novelty seeking (b = 0.18, pObese individuals showed a distinct temperament profile and circulating endocannabinoids compared to controls.

    Full Text Available Endocannabinoids and temperament traits have been linked to both physical activity and body mass index (BMI however no study has explored how these factors interact in females. The aims of this cross-sectional study were to 1 examine differences among distinct BMI groups on daytime physical activity and time spent in moderate-vigorous physical activity (MVPA, temperament traits and plasma endocannabinoid concentrations; and 2 explore the association and interaction between MVPA, temperament, endocannabinoids and BMI.Physical activity was measured with the wrist-worn accelerometer Actiwatch AW7, in a sample of 189 female participants (43 morbid obese, 30 obese, and 116 healthy-weight controls. The Temperament and Character Inventory-Revised questionnaire was used to assess personality traits. BMI was calculated by bioelectrical impedance analysis via the TANITA digital scale. Blood analyses were conducted to measure levels of endocannabinoids and endocannabinoid-related compounds. Path-analysis was performed to examine the association between predictive variables and MVPA.Obese groups showed lower MVPA and dysfunctional temperament traits compared to healthy-weight controls. Plasma concentrations of 2-arachidonoylglyceryl (2-AG were greater in obese groups. Path-analysis identified a direct effect between greater MVPA and low BMI (b = -0.13, p = .039 and high MVPA levels were associated with elevated anandamide (AEA levels (b = 0.16, p = .049 and N-oleylethanolamide (OEA levels (b = 0.22, p = .004, as well as high Novelty seeking (b = 0.18, p<.001 and low Harm avoidance (b = -0.16, p<.001.Obese individuals showed a distinct temperament profile and circulating endocannabinoids compared to controls. Temperament and endocannabinoids may act as moderators of the low MVPA in obesity.

    The relationships between grapevine (Vitis vinifera) vigor variation and resulting wine anthocyanin concentration and composition and pigmented polymer formation were investigated. The study was conducted in a commercial vineyard consisting of the same clone, rootstock, age, and vineyard management practices. Vine vigor parameters were used to designate vigor zones within two vineyard sites (A and B) to produce research wines (2003 and 2004) and conduct a model extraction experiment (2004 only) to investigate the vine-fruit-wine continuum. Wines and model extracts were analyzed by HPLC and UV-vis spectrophotometry. For the model extractions, there were no differences between sites for pomace weight, whereas juice volume was higher for site A. This was not related to a larger berry size. Site A had a higher anthocyanin concentration (milligrams per liter) in the model extracts than site B specifically for the medium- and low-vigor zones. For anthocyanin composition in the model extraction, site B had a greater proportion of malvidin-3-O-glucoside and less of the remaining anthocyanin glucosides (delphinidin, cyanidin, petunidin, and peonidin) compared to site A. In the wines, there was a vintage effect, with the 2003 wines having a higher anthocyanin concentration (milligrams per liter) than the 2004 wines. This appears to have been primarily due to a greater accumulation of anthocyanins in the fruit. In general, the medium-vigor zone wines had higher anthocyanin concentrations than either the high- or low-vigor zone wines. There was also vintage variation related to anthocyanin composition, with the 2003 wines having a higher proportion of delphinidin and petunidin glucosides and lower malvidin-3-O-glucoside compared to 2004. In both years, there were higher proportions of delphinidin and petunidin glucosides in wines made from low-vigor-zone fruit. Wines made from low-vigor zones showed a greater propensity to form vitisin A as well as pigmented polymers. Low-vigor

    Full Text Available ABSTRACT: Crataeva tapia L. is a fruit native to the Brazilian savanna, the Caatinga, and is used in the production of soft drinks and other beverages. Given the importance of this species and the lack of knowledge about its seeds, this research aimed to evaluate the physiological quality of C. tapia L. seeds subjected to different environments and drying periods. Seeds were dried for the following time periods: 0 (no drying, 24, 48, 72, 96, and 120 hours, in the laboratory environment (25°C and 90% RH and in a greenhouse (30°C and 80% RH. After the drying period, seeds from each of the treatments were used for determining the water content, germination, and vigor (using tests for emergence, first count of germination and emergence, rate of germination and emergence, length, and seedling dry weight. The experimental design was completely randomized and a factorial 2×6 scheme (local environment × drying periods was used with four replicate sets of seeds. The data were subjected to analysis of variance and polynomial regression using quadratic models. The germination and seed vigor reduced as the drying periods increased. For optimum results, the seeds of C. tapia L. must be dried in the laboratory for a period of 48 hours. In addition, their desiccation resistance was classified as intermediate.

    Workplace bullying has been classified as an extreme social stressor in work contexts and has been repeatedly linked to several negative consequences. However, little research has examined reversed or reciprocal relations of bullying and outcomes. We conducted a two-wave longitudinal study with a time lag of six months. The study sample consisted of 348 employees of the Spanish workforce. The present study examined longitudinal relationships between workplace bullying, psychological health, and well-being. On the basis of conservation of resources theory, we hypothesized that we would find reciprocal relations among study variables over time. Results of cross-lagged structural equation modeling analyses supported our hypotheses. Specifically, it was found that Time 1 (T1) workplace bullying was negatively related to Time 2 (T2) vigor and positively related to T2 anxiety. Additionally, T1 anxiety and vigor had an effect on T2 workplace bullying. Overall, these findings support the validity of the theoretical models postulating a reciprocal bullying-outcome relationship, rather than simple one-way causal pathways approaches.

    The purpose of this study was to examine the effect of oral contraceptive (OC) use on salivary secretory immunoglobulin A (SIgA) levels at rest and in response to an acute bout of moderate-vigorous exercise during 2 phases of the 4-week OC cycle corresponding to different phases of the synthetic menstrual cycle. Ten healthy active females completed a cycling at 70% peak oxygen uptake for 45 min at 2 time points of an OC cycle: during the equivalent in time to the mid-follicular phase (day 8 ± 2) and the mid-luteal phase (day 20 ± 2). Timed unstimulated saliva samples were obtained before, immediately postexercise, and 1 h postexercise and analyzed for salivary SIgA. Salivary SIgA secretion rate was 26% (95% confidence limits (CI) 6-46) lower at postexercise compared with pre-exercise during the synthetic follicular phase (p = 0.019) but no differences were observed during the synthetic luteal trial. Saliva flow rate was 11% (95% CI, 8-30) lower at postexercise compared with pre-exercise (main effect for time; p = 0.025). In conclusion, the pattern of salivary SIgA secretion rate response to moderate-vigorous exercise varies across the early and late phases of a monophasic OC cycle, with a transient reduction in salivary SIgA responses during the synthetic follicular phase. These findings indicate that monophasic OC use should be considered when assessing mucosal immune responses to acute exercise.

    Full Text Available In recent years, essential oils have gained commercial interest in the agricultural area, mainly for their allelopathic, insecticidal, antifungal, antimicrobial and antioxidant properties, and, also for their natural compounds, which have generally displayed low toxicity, relatively low cost and rapid degradation in the environment. Medicinal plants have emerged as potential suppliers of essential oils because of their ethnopharmacological utility. The aim of this study was to evaluate the allelopathic potential of essential oils extracted from fresh leaves of lemon grass (Cymbopogon citratus, wild basil (Ocimum gratissimum L. and sweet basil (Ocimum basilicum L. with regard to their major constituents (citral, eugenol and cineol, respectively in different application forms (direct contact and the effect of volatile constituents on the germination and vigor of lettuce seeds (cultivar Regina SF 3500. The effects of the oils and their major components were evaluated with regard to the variables: first germination count, total germination, GVI (germination velocity index, seedling dry weight and average lengths of shoots and lettuce roots. The essential oils from lemon grass and basil displayed allelopathic potentials on seed germination and vigor of lettuce achenes that can be assigned to their respective major constituents citral and eugenol. On the other hand, the allelopathic effect of the essential oil from basil was a consequence of the combined effect of all the components, regardless the application method.

    Full Text Available Abstract Objective: To assess the acute effect of vigorous aerobic exercise on the inhibitory control in adolescents. Methods: Controlled, randomized study with crossover design. Twenty pubertal individuals underwent two 30-minute sessions: (1 aerobic exercise session performed between 65% and 75% of heart rate reserve, divided into 5 min of warm-up, 20 min at the target intensity and 5 min of cool down; and (2 control session watching a cartoon. Before and after the sessions, the computerized Stroop test-Testinpacs™ was applied to evaluate the inhibitory control. Reaction time (ms and errors (n were recorded. Results: The control session reaction time showed no significant difference. On the other hand, the reaction time of the exercise session decreased after the intervention (p<0.001. The number of errors made at the exercise session were lower than in the control session (p=0.011. Additionally, there was a positive association between reaction time (Δ of the exercise session and age (r2=0.404, p=0.003. Conclusions: Vigorous aerobic exercise seems to promote acute improvement in the inhibitory control in adolescents. The effect of exercise on the inhibitory control performance was associated with age, showing that it was reduced at older age ranges.

    Regular physical activity has substantial health benefits in persons with type 1 diabetes, including reduced risk of complications and cardiovascular mortality as well as improved self-rated quality of life. Despite these benefits, individuals with type 1 diabetes are often less active than their peers without diabetes. When factors such as time constraints, work pressure and environmental conditions are often cited as barriers to physical activity in the general population, 2 additional major factors may also explain the low rates of physical activity in young people with type 1 diabetes: (1) fear of hypoglycemia both during and after (particularly overnight) exercise and (2) a lack of empiric evidence for the efficacy of physical activity for achieving optimal glycemic control. A number of acute exercise trials recently showed that the inclusion of vigorous intensity physical activity in conventional moderate intensity (i.e. walking and light cycling) exercise sessions may overcome these barriers. No studies have tested the efficacy of high-intensity physical activity on glycemic control (A1C) or post-exercise hypoglycemia in a randomized controlled trial. This article summarizes the literature related to the role of physical activity for the management of blood glucose levels in individuals with type 1 diabetes and provides a rationale for the need of a randomized controlled trial examining the effects of vigorous-intensity physical activity on blood glucose control.

    Full Text Available Physical inactivity is a leading factor associated with cardiovascular disease and a major contributor to the global burden of disease in developed countries. Subjective mood states associated with acute exercise are likely to influence future exercise adherence and warrant further investigation. The present study examined the effects of a single bout of vigorous exercise on mood and anxiety between individuals with substantially different exercise participation histories. Mood and anxiety were assessed one day before an exercise test (baseline, 5 minutes before (pre-test and again 10 and 25 minutes post-exercise. Participants were 31 university students (16 males, 15 females; Age M = 20, with 16 participants reporting a history of regular exercise with the remaining 15 reporting to not exercise regularly. Each participant completed an incremental exercise test on a Monark cycle ergometer to volitional exhaustion. Regular exercisers reported significant post-exercise improvements in mood and reductions in state anxiety. By contrast, non-regular exercisers reported an initial decline in post-exercise mood and increased anxiety, followed by an improvement in mood and reduction in anxiety back to pre-exercise levels. Our findings suggest that previous exercise participation mediates affective responses to acute bouts of vigorous exercise. We suggest that to maximise positive mood changes following exercise, practitioners should carefully consider the individual's exercise participation history before prescribing new regimes.

    Full Text Available The Albizia niopoides, popularly known as white mimosa, is a native forest species of fast-growing and with high potential for reforestation purposes. However, there is little information about its seminiferous spread. Thus, this study aimed to evaluate the germination performance and vigor of A. niopoides seed under different water volumes for substrate moistening. The experimental design was completely randomized with four replicates and each replicate with 25 seeds. The seeds were sown on germitest paper (arranged in rolls moistened with water volumes equivalent to 1.0; 1.5; 2.0; 2.5; 3.0; 3.5; and 4.0 times the dry weight (DW of the substrate without further water addition. Germination occurred in a germination chamber (Biochemical Oxygen Demand-B.O.D-type set at 25 °C and continuous light. The analyzed variables were percentage of germination, length of shoot and primary root, dry weight of shoot, and root seedling system. Decreasing effect on germination percentage values, primary root length, and dry weight of the root system from the substrate moistening with the water volume equivalent to 2.0 times its dry weight were found. Water volumes in the range of 1.0 to 2.0 times the mass of paper favor the germination and vigor of A. niopoides seed.

    Full Text Available The aim of this research was to test if mean germination time (MGT can predict seed vigor in 10 seed lots of canola. There was a significant difference between the final germination percentages of the 10 seed lots tested (‘Hyola 330’, ‘Hyola 401’, ‘Okapi’, ‘Elite’, ‘SLMO 46’, ‘Zarfam’, ‘RGS 003’, ‘Option 500’, ‘Echo’, ‘Rainbow’ and a highly significant correlation between MGT and this value. Of the 10 seed lots, ‘Hyola 330’ had the lowest final percentage germination (62% and the highest MGT, 3.64 days. The correlation between MGT and the proportion of “normal” seedlings was also significant. ‘Hyola 330’ had the lowest percentage of normal seedlings (60%. A tetrazolium test showed that this lot had some dead seeds that could not germinate; some seeds were viable, but they would produce abnormal seedlings. One of the main reasons of low final germination percentage and high MGT in ‘Hyola 330’ was low viability of this seed lot. Mean germination time is suggested as a good indicator of seed vigor in canola.

    One of the key tasks for disaster risk reduction is raising awareness. On way to increase it is through risk communication, including visual risk communication. Previous research showed that visual risk communication linked to natural hazards is mostly evaluated in terms of user's requirements, ability to understand the content, or satisfaction with the diverse components of the tool(s): Its impact on risk awareness is not researched. Most of the risk communication evaluations are performed in a lab-type environments and thus their conclusions might not be fully valid in real life settings. Our approach differs in the sense that we decided to test a real communication effort. However, we did not use an existing one but designed our own. This process was conducted according to collaborative research principles, meaning that we created the communication effort in collaboration with the local stakeholders in order to respect the social environment of the case study. Moreover, our research activity should be beneficial and significant for the community in which we work as well as for science. This contribution will present the process that allowed us to design an exhibition in the Ubaye Valley (France) and the methodology that was developed to measure changes in risk awareness. During a 2-years project, we collaborated with local and regional stakeholders (politicians and technicians). Informal meetings with local stakeholders were organized to determine what they perceived as the needs in term of risk communication and to investigate the potential to develop activities that would benefit both them and us. We were offered the opportunity to design an exhibition for the local public library. We proposed the content and this was adjusted in interaction with the stakeholders. Later local technicians and inhabitants contributed to the content of the exhibition and regional stakeholders helped with the funding of the exhibition. Finally, employees of the public library took

    Full Text Available Since 1997 universities in South Africa have been encouraged to be responsive to the needs of communities, to encourage broader participation and to address issues of access in higher education (Department of Education 1997. This transformative agenda was found to be especially compelling in the case of rural-based South African universities, which often serve historically disadvantaged black populations in areas that are both under-resourced and underdeveloped (Nkomo & Sehoole 2007, pp. 235–36. In 2006 the traditional leadership of a local community approached the University of Venda to propose a partnership. This prompted the researcher to conduct a qualitative study, which sought to explore and describe community members’ views of what they understood to be a quality partnership. Thirty-seven community representatives were engaged in individual as well as focus group interviews. These representatives were identified first through a stakeholder analysis procedure that sought to determine who in the community would have valuable input for the university-community partnership. As a point of departure, the following two questions were asked consecutively: What are your needs and expectations of a partnership with the university and what would you regard as a quality partnership between the HEI and the community? The sample selection was purposive, utilising the snowball technique. Data was transcribed and analysed using Tesch’s eight-step method (Tesch 1990, in Creswell 1994, p. 155. Interview data and field notes were co-coded, crosschecked and triangulated. Feedback workshops were conducted with the community to confirm the findings. A consensus was reached that four main requirements emerged from the data: —Balance the partnership objectives of both parties —Ensure an unexploitative partnership —Share power and control in the partnership —Maintain and monitor the partnership.

    Full Text Available Motivation, in a narrow meaning, based on a classical vision on the organisation and management, aims only at the employees or staff of the organization. This optics still predominates both in theory and in the worldwide managerial practice. Motivation, in a broad meaning, contoured in recent years, based on a modern vision on the organization and management is centred on the stakeholders, namely on those people, categories of staff and organisms who have major interests in developing the activity and performances of the organisation. In order to understand motivation, the managers must first understand the reasons why the individuals behave in a certain way and for which they have certain reactions under threatening situations or by which influencing is attempted. Motivation is an internal process, not an imperative one which can be compelled from the outside. Managers must understand the motivation strategies, the way in which they succeed or fail on the grounds of the way in which they succeed in influencing the inner motivations of the employees.

    Since August of 2001, Bob Lawrence and Associates, Inc. (BL&A) has applied its outreach and support services to lead a highly effective work effort on behalf of Wind Powering America (WPA). In recent years, the company has generated informative brochures and posters, researched and created case studies, and provided technical support to key wind program managers. BL&A has also analyzed Lamar, Colorado’s 162MW wind project and developed a highly regarded 'wind supply chain' report and outreach presentation. BL&A’s efforts were then replicated to characterize similar supply chain presentations in New Mexico and Illinois. Note that during the period of this contract, the recipient met with members of the DOE Wind Program a number of times to obtain specific guidance on tasks that needed to be pursued on behalf of this grant. Thus, as the project developed over the course of 5 years, the recipient varied the tasks and emphasis on tasks to comply with the on-going and continuously developing requirements of the Wind Powering America Program. This report provides only a brief summary of activities to illustrate the recipient's work for advancing wind energy education and outreach from 2001 through the end of the contract period in 2006. It provides examples of how the recipient and DOE leveraged the available funding to provide educational and outreach work to a wide range of stakeholder communities.

    Vigorous intravenous fluid resuscitation (IVFR) was reported to reduce post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis in a pilot study. We performed a randomized, double-blind controlled trial to establish whether periprocedural vigorous IVFR reduces the risk of post-ERCP pancreatitis. A total of 510 patients with native papilla at 3 tertiary referral centers in Korea were randomly assigned (1:1) to groups given vigorous IVFR (lactated Ringer's solution in an initial bolus of 10 mL/kg before the procedure, 3 mL/kg/h during the procedure, for 8 hours after the procedure, and a post-procedure bolus of 10 mL/kg) or a standard IVFR (lactated Ringer's solution at 1.5 mL/kg/h during and for 8 hours after the procedure). The primary end point of the study was the development of post-ERCP pancreatitis, and the secondary end point was severity of pancreatitis, hyperamylasemia, and fluid overload. The main indications for ERCP were choledocholithiasis (58%) and malignant biliary stricture (27%). Post-ERCP pancreatitis developed in 11 patients in the vigorous IVFR group (4.3%) and 25 patients in the standard IVFR group (9.8%) (relative risk, 0.41; 95% CI, 0.20-0.86; P = .016). Moderate or severe acute pancreatitis occurred in a significantly smaller proportion of patients in the vigorous IVFR group (0.4%) than in the standard IVFR group (2.0%; P = .040). One patient in the vigorous IVFR group developed peripheral edema. In a double-blind, randomized controlled trial, we found vigorous periprocedural intravenous hydration with lactated Ringer's solution to reduce the incidence and severity of post-ERCP pancreatitis in average-risk and high-risk cases. IVFR is not associated with increased adverse events. ClinicalTrials.gov number: NCT02308891. Copyright © 2017. Published by Elsevier Inc.

    2013-10-01

    Psoriasis is associated with serious comorbidities such as cardiovascular disease, type 2 diabetes, and metabolic syndrome. These comorbidities are related to low physical activity in the general population. Limited research has evaluated physical activity in psoriasis, and thus, the purpose of this investigation was to compare physical activity between individuals with and without psoriasis as well as explore the associations between measures of psoriasis severity and physical activity. Cross-sectional study using data from the 2003-2006 National Health and Nutrition Examination Survey. Self-reported psoriasis diagnosis and psoriasis severity were regressed on moderate/vigorous physical activity, as measured objectively by accelerometers. Measures of psoriasis severity included rating of psoriasis as a problem in life and body surface area involvement. A total of 4316 individuals had data on psoriasis, moderate/vigorous physical activity, and relevant covariates, with 3.6% (population weighted) of participants (N.=117) reporting a diagnosis of psoriasis. A psoriasis diagnosis was not associated with moderate/vigorous physical activity, and furthermore, body surface area involvement was not associated with moderate/vigorous physical activity among participants with psoriasis. However, every tertile increase in psoriasis as a problem in life was associated with 28% less moderate/vigorous physical activity, which remained significant after adjusting for covariates and removing outliers. While a diagnosis of psoriasis and body surface area involvement do not appear to be associated with less moderate/vigorous physical activity, individuals that rate their psoriasis to be a large problem engage in less moderate/vigorous physical activity.

    Full Text Available Stakeholder participation has received increased attention as a key process for enhancing mitigation of conflicts between different interests for the same resources and transparent decision-making in marine protected areas (MPAs. A wide range of advanced web tools is available nowadays that integrate stakeholder participation by generating new information and allow interaction between actors in MPA management. However, such technologies are frequently used without much consideration regarding the complexity of the decision to be made and the heterogeneity of stakeholder preferences and understanding in order to be related to these technologies. In order to understand how technology corresponds to the changing needs of MPA management, we have reviewed a range of different participation strategies adopted by web technology, based on a set of criteria that define a successful participation approach. We start from simple towards more sophisticated tools that have been developed worldwide in order to better inform decisions, and contribute to more effective and efficient MPA management. Finally, we draw a theoretical framework for the development of a community-based web tool with the capacity to incorporate the philosophy of stakeholder participation by generating new and high quality information flow for effective MPA management.

    Full Text Available Objective – The purpose of this study is to understand how top Brazilian firms think about and communicate value creation to their stakeholders. Design/methodology/approach – We use qualitative content analysis methodology to analyze the sustainability or annual integrated reports of the top 25 Brazilian firms by sales revenue. Findings – Based on our analysis, these firms were classified into three main types of stakeholder value creation models: narrow, broad, or transitioning from narrow to broad. We find that many of the firms in our sample are in a transition state between narrow and broad stakeholder value creation models. We also identify seven areas of concentration discussed by firms in creating value for stakeholders: better stakeholder relationships, better work environment, environmental preservation, increased customer base, local development, reputation, and stakeholder dialogue. Practical implications – This study shows a trend towards broader stakeholder value creation models in Brazilian firms. The findings of this study may inform practitioners interested in broadening their value creation models. Originality/value – This study adds to the discussion of stakeholder theory in the Brazilian context by understanding variations in value creation orientation in Brazil.

    The three stakeholders (coaches, parents and the National Governing Body) in Talent Identification and Development (TID) are important factors in athlete development. How each of them perceive the key constructs of Talent Identification and Development (i.e. sport specialisation and selection, practice, athlete development, junior and adult success, and the role of the stakeholders), and the coherence of that understanding is not well understood. This study focuses on junior performance tennis and investigates the perceptions of coaches, parents and sports organisations (a National Governing Body) of the five key constructs of Talent Identification and Development. We were interested in examining (a) the extent to which stakeholder perceptions relate to research, (b) the coherence of each stakeholder's perceptions and (c) the extent to which there is coherence between what stakeholders understand each other thinks. Seventy-five coaches, parents, and National Governing Body staff completed a questionnaire that asked participants to rate their degree of agreement/disagreement with researched 'principles' of Talent Identification and Development. The results suggest that stakeholders do not strongly agree with the research supporting principles of Talent Identification and Development. Furthermore, a significant lack of coherence of stakeholder perceptions was evident. This lack of coherence was also evident in each group's understanding of what the other stakeholders believed. The impact of these results on the Talent Identification and Development process is discussed.

  13. Surface EMG system for use in long-term vigorous activities

    Science.gov (United States)

    de Luca, G.; Bergman, P.; de Luca, C.

    The purpose of the project was to develop an advanced surface electromyographic (EMG) system that is portable, un-tethered, and able to detect high-fidelity EMG signals from multiple channels. The innovation was specifically designed to extend NASA's capability to perform neurological status monitoring for long-term, vigorous activities. These features are a necessary requirement of ground-based and in-flight studies planned for the International Space Station and human expeditions to Mars. The project consisted of developing 1) a portable EMG digital data logger using a handheld PC for acquiring the signal and storing the data from as many as 8 channels, and 2) an EMG electrode/skin interface to improve signal fidelity and skin adhesion in the presence of sweat and mechanical disturbances encountered during vigorous activities. The system, referred to as a MyoMonitor, was configured with a communication port for downloading the data from the data logger to the PC computer workstation. Software specifications were developed and implemented for programming of acquisition protocols, power management, and transferring data to the PC for processing and graphical display. The prototype MyoMonitor was implemented using a handheld PC that features a color LCD screen, enhanced keyboard, extended Lithium Ion battery and recharger, and 128 Mbytes of F ash Memory. The system was designed to be belt-worn,l thereby allowing its use under vigorous activities. The Monitor utilizes up to 8 differential surface EMG sensors. The prototype allowed greater than 2 hours of continuous 8-channel EMG data to be collected, or 17.2 hours of continuous single channel EMG data. Standardized tests in human subjects were conducted to develop the mechanical and electrical properties of the prototype electrode/interface system. Tests conducted during treadmill running and repetitive lifting demonstrated that the prototype interface significantly reduced the detrimental effects of sweat

    Esther M F van Sluijs

    Full Text Available BACKGROUND: Correlates of physical activity (PA are hypothesized to be context and behaviour specific, but there is limited evidence of this in young children. The aim of the current study is to investigate associations between personal, social and environmental factors and objectively measured light and moderate-to-vigorous PA (LPA and MVPA, respectively in four-year-old children. METHODS: Cross-sectional data were used from the Southampton Women's Survey, a UK population-based longitudinal study. Four-year old children (n = 487, 47.0% male had valid PA data assessed using accelerometry (Actiheart and exposure data collected with a validated maternal questionnaire (including data on child personality, family demographics, maternal behaviour, rules and restrictions, and perceived local environment. Linear regression modelling was used to analyse associations with LPA and MVPA separately, interactions with sex were explored. RESULTS: LPA minutes were greater in children whose mothers reported more PA (vs. inactive: regression coefficient±standard error: 6.70±2.94 minutes, and without other children in the neighbourhood to play with (-6.33±2.44. MVPA minutes were greater in children with older siblings (vs. none: 5.81±2.80 and those whose mothers used active transport for short trips (vs. inactive: 6.24±2.95. Children accumulated more MVPA in spring (vs. winter: 9.50±4.03 and, in boys only, less MVPA with availability of other children in the neighbourhood (-3.98±1.70. DISCUSSION: Young children's LPA and MVPA have differing associations with a number of social and environmental variables. Interventions targeting PA promotion in young children outside of formal care settings should consider including intensity specific factors.

    Previous research suggests the neighborhood environment may be an important influence on children’s physical activity (PA) behaviors; however, findings are inconsistent. The purpose of this study was to further understand the relationship between perceptions of the neighborhood environment and children’s afterschool moderate-to-vigorous PA (MVPA). Utilizing a structural equation modeling technique, we tested a conceptual model linking parent and child perceptions of the neighborhood environment, parent support for PA, and child outdoor PA with children’s afterschool MVPA. We found that child perception of the neighborhood environment and outdoor PA were positively associated with afterschool MVPA. In addition, parent support for PA positively influenced children’s outdoor PA. The neighborhood environment and outdoor activity appear to play an influential role on children’s afterschool PA behaviors. PMID:25679820

    Full Text Available This study aimed at investigating the relationship between a set of variables (adolescents' gender, age, economic level, nutritional status, and fathers' educational level and physical activity practices. The sample consisted of 578 students from a public school, aged between 11 and 16 years. The International Physical Activity Questionnaire (IPAQ, version 8, short form was applied in order to measure their physical activity practices. Chi-square, independent t test and one-way ANOVA were implemented. Thirteen percent of adolescents were physically inactive and no significant difference was found between gender (p > .05. Compared to boys, girls spent more time in walking (p = .019 and vigorous activities (p = .017. Adolescents aged 14-16 years spent more time in walking compared with those aged 11-12 years (p = .026 and 13-year-olds (p = .006. There was a positive association between economic level and time spent in moderate physical activity (p = .034.

  20. Vigorous intensity physical activity is related to the metabolic syndrome independent of the physical activity dose.

    2012-08-01

    Current physical activity guidelines imply that, by comparison with moderate physical activity (MPA), the benefits of engaging in vigorous physical activity (VPA) are attributed to the greater energy expenditure dose per unit of time and do not relate to intensity per se. The purpose of this study was to determine whether VPA influences the metabolic syndrome (MetS) independent of its influence on the energy expenditure dose of moderate-to-vigorous physical activity (MVPA). Participants consisted of 1841 adults from the 2003-06 National Health and Nutrition Examination Survey, a representative cross-sectional study. MPA and VPA were measured objectively over 7 days using Actigraph accelerometers. MetS was determined using an established clinical definition. Associations between physical activity and the MetS were determined using logistic regression and controlled for relevant covariates. Analyses revealed that VPA remained a meaningful predictor of the MetS after controlling for the total energy expenditure dose of MVPA such that the relative odds of the MetS was 0.28 (95% confidence interval 0.17-0.46) in the group with the highest VPA compared with the group with no VPA. VPA had a greater influence on the MetS than an equivalent energy expenditure dose of MPA. For instance, between 0 and 500 MET min/week of MPA the adjusted prevalence of the MetS decreased by 15.5%, whereas between 0 and 500 MET min/week of VPA the prevalence decreased by 37.1%. These cross-sectional findings suggest that VPA per se has an important role in cardiometabolic disease prevention.

    Monitoring physical activity intensity in persons with Down syndrome (DS) may be affected by an altered relationship between metabolic equivalent units (METs) and step-rate. This study examined whether the relationship between METs and step-rate is altered in persons with DS and developed step-rate thresholds for activity intensity for these persons. Cross-sectional. Eighteen persons with DS (25±7years; 8 women) and 22 persons without DS (26±5 years; 9 women) completed six over-ground walking trials each lasting 6 min at their preferred speed and at 0.5, 0.75, 1.0, 1.25, and 1.5 ms⁻¹. METs were measured with portable spirometry and step-rate with hand-tally. Random effects models were used to predict METs from step-rate, squared step-rate, height, presence of DS, sex, and body mass index (BMI). Step-rate, squared step-rate, height, and presence of DS contributed significantly to the model (SE=0.20 METs; R²=0.63); sex and BMI did not contribute. As height increased, step-rate thresholds for moderate and vigorous-intensity activity decreased. For a given height, participants with DS had lower step-rate at the moderate-intensity threshold than participants without DS. Across participant heights, the moderate-intensity cut-off ranged between 101 and 76 steps min⁻¹ in persons with DS and between 103 and 80 steps min⁻¹ in persons without DS. For persons with DS, step-rate at the vigorous-intensity threshold ranged between 136 and 126 steps min⁻¹. Persons with DS showed altered relationship between METs and step-rate and had lower step-rate thresholds for moderate-intensity activity than persons without DS.

    The present study examined the sex-specific associations of moderate and vigorous physical activity (VPA) with physical fitness in 300 Japanese adolescents aged 12-14 years. Participants were asked to wear an accelerometer to evaluate physical activity (PA) levels of various intensities (i.e. moderate PA (MPA), 3-5.9 metabolic equivalents (METs); VPA, ≥6 METs; moderate to vigorous PA (MVPA), ≥3 METs). Eight fitness items were assessed (grip strength, bent-leg sit-up, sit-and-reach, side step, 50 m sprint, standing long jump, handball throw, and distance running) as part of the Japanese standardised fitness test. A fitness composite score was calculated using Japanese fitness norms, and participants were categorised according to their score from category A (most fit) to category E (least fit), with participants in categories D and E defined as having low fitness. It was found that for boys, accumulating more than 80.7 min/day of MVPA may reduce the probability of low fitness (odds ratio (ORs) [95% confidence interval (CI)] = 0.17 [0.06-0.47], p = .001). For girls, accumulating only 8.4 min of VPA could reduce the likelihood of exhibiting low fitness (ORs [95% CI] = 0.23 [0.05-0.89], p = .032). These results reveal that there are sex-specific differences in the relationship between PA and physical fitness in adolescents, suggesting that sex-specific PA recommendation may be needed to improve physical fitness in adolescents.

  3. Relationship between stakeholders' information value perception and information security behaviour

    2015-02-01

    The study, reported in this paper, aims to explore the relationship between the stakeholders' perceptions about the value of information and their resultant information security behaviours. Moreover, this study seeks to explore the role of national and organisational culture in facilitating information value assignment. Information Security is a concept that formed from the recognition that information is valuable and that there is a need to protect it. The ISO 27002 defines information as an asset, which, like other important business assets, is essential to an organisation's business and consequently needs to be appropriately protected. By definition, an asset has a value to the organisation hence it requires protection. Information protection is typically accomplished through the implementation of countermeasures against the threats and vulnerabilities of information security, for example, implementation of technological processes and mechanisms such as firewall and authorization and authentication systems, set-up of deterrence procedures such as password control and enforcement of organisational policy on information handling procedures. However, evidence routinely shows that despite such measures, information security breaches and incidents are on the rise. These breaches lead to loss of information, personal records, or other data, with consequent implications for the value of the information asset. A number of studies have suggested that such problems are not related primarily to technology problems or procedural deficiencies, but rather to stakeholders' poor compliance with the security measures that are in place. Research indicates that compliance behaviour is affected by many variables including perceived costs and benefits, national and organisational culture and norms. However, there has been little research to understand the concept of information value from the perspective of those who interact with the data, and the consequences for information

  4. Objectives for Stakeholder Engagement in Global Environmental Assessments

    2017-09-01

    Full Text Available Global environmental assessments (GEAs are among the most large-scale, formalized processes for synthesizing knowledge at the science–policy–society interface. The successful engagement of diverse stakeholders in GEAs is often described as a crucial mechanism for increasing their legitimacy, salience and credibility. However, the diversity of perspectives on the more precise objectives for stakeholder engagement remains largely unclear. The aims of this study are to categorize and characterize the diversity of perspectives on objectives for stakeholder engagement in GEAs; to explore differences in perspectives within and between different stakeholder groups and categories; and to test whether the more practical prioritization and selection of objectives in GEAs can be linked to deliberative policy learning as a higher-level rationale for stakeholder engagement. For these purposes, we conduct a grounded theory analysis and a keyword analysis of interview material and official GEA documents relating to two GEAs: UN Environment’s Fifth Global Environment Outlook and the Working Group III contribution to the Intergovernmental Panel on Climate Change Fifth Assessment Report. Based on the analysis, we identify six categories of objectives and present as hypotheses promising ways forward for prioritizing and characterizing objectives for stakeholder engagement in GEAs, as well as potential reasons for the differences between perspectives on objectives. This study draws attention to the need for future GEA processes to have more explicit discussions on the objectives for stakeholder engagement, as well as the importance of moving towards increasingly deliberative and inclusive assessment processes more broadly.

    In EU project CLIMRUN, there has been a continuous interaction with stakeholders and end-users to develop new and improved tools to extract useful and useable information tailored to the needs of specific sectors. In this work, we review the provision of climate information services required in the Mediterranean country of Greece where forest fires represent a major hazard. Intense terrain, sparsely vegetated with typical Mediterranean flora makes Greece a fire prone environment. That, in addition to the abandonment of rural lands and extreme weather conditions due to climate change the last few decades, constitutes an issue of an annual cycle of catastrophe from forest fires. An iterative and bottom-up (i.e. stakeholder led) approach for optimizing the two-way information transfer between climate experts and stakeholders has been adopted from the start of the project with a workshop in Athens helping to define the framework for the forest fires case study. The main objectives of this workshop were to better understand who the wildfires stakeholders are and what they need from climate services. After the first workshop three main categories of stakeholders were identified: short term fire planners, long term policy makers and education stakeholders. To address the needs of these stakeholders' categories the following actions were taken: 1. In collaboration with the forecasting team at the National Observatory of Athens, an application providing fire risk forecasts for the following 3 days (http://cirrus.meteo.noa.gr/forecast/bolam/index.htm) was developed, to address the needs of short term fire planners. 2. A web-based application providing long term fire risk and other fire related indices changes due to climate change (time horizon up to 2050 and up to 2100) was developed in collaboration with the Greek WWF office, to address the needs of long term fire policy makers (http://www.oikoskopio.gr/map/). 3.

    In the NIOSH Generic Job Stress Model, social support is assumed to moderate the relationship between job stressors and stress responses. However, few studies have investigated how to enhance social support in the workplace. The purpose of this study was to explore the relationships between interpersonal helping behavior, social support, job stressors, psychological stress responses, and vigor among Japanese workers. A total of 240 workers in manufacturing companies returned a questionnaire regarding their interpersonal helping behavior, social support, job stressors, psychological stress responses, and vigor (response rate = 96.0%). After excluding 40 participants due to missing responses, data from a total of 200 participants (163 male and 37 female, mean age = 40.3 yr) were used in the final analyses. Interpersonal helping behavior was assessed by the Japanese version of the Organizational Citizenship Behavior Scale. The Brief Job Stress Questionnaire was used to measure job stressors, psychological stress responses, social support, and vigor. Structured equation modeling was performed to examine the relationships between interpersonal helping behavior, social support, job stressors, psychological stress responses, and vigor. Interpersonal helping behavior had a statistically significant negative effect on psychological stress response through increasing social support. However, interpersonal helping behavior had a statistically significant positive effect on psychological stress response through increasing the quantitative workload. Of these two effects, the former was stronger than the latter. In addition, interpersonal helping behavior had a statistically significant positive effect on vigor through increasing social support. Although interpersonal helping behavior, which helps other workers may increase quantitative workload, leading to high levels of psychological stress responses, that same behavior strengthens trust and team spirit among workers and may

    Social computing technologies are transforming the way our society interacts and generates content on the Web via collective intelligence. Previously unimagined possibilities have arisen for using these technologies to engage stakeholders and involve them in policy making and planning efforts. While the Internet has been used in the past to support education and communication endeavors, we have developed a novel, web-based, interactive planning tool that engages the community in using science-based methods for the design of potential conservation practices on their landscape, and thereby, reducing undesirable impacts of extreme hydroclimatic events. The tool, Watershed REstoration using Spatio-Temporal Optimization of Resources (WRESTORE), uses a democratic voting process coupled with visualization interfaces, computational simulation and optimization models, and user modeling techniques to support a human-centered design approach. This human-centered design approach, which is reinforced by use of Web 2.0 technologies, has the potential to enable policy makers to connect to a larger community of stakeholders and directly engage them in environmental stewardship efforts. Additionally, the design framework can be used by watershed groups to plug-in their own hydrologic models, climate observations and forecasts, and various other simulation models unique to their watersheds. In this presentation, we will demonstrate the effectiveness of WRESTORE for designing alternatives of conservation practices in a HUC-11 Midwestern watershed, results of various experiments with a diverse set of test users and stakeholders, and discuss potential for future developments.

    Rotarius, Timothy

    Communities are composed of many organizations. These organizations naturally form clusters based on common patterns of knowledge, skills, and abilities of the individual organizations. Each of these spontaneous clusters represents a distinct knowledge base. The health care knowledge base is shown to be the natural leader of any community. Using the Central Florida region's 5 knowledge bases as an example, each knowledge base is categorized as a distinct type of stakeholder, and then a specific stakeholder management strategy is discussed to facilitate managing both the cooperative potential and the threatening potential of each "knowledge base" stakeholder.

  11. Understanding dyadic promoter-stakeholder relations in complex projects

    2016-01-01

    Full Text Available In this study, we propose a Bilateral Double Motive framework of stakeholder cooperation in complex projects. The framework analyses and explains dyadic promoter-stakeholder relationships at a micro level by acknowledging both transactional and relational motives. We demonstrate the framework’s usefulness by illustrating its explanatory power in two instances of cooperation and two of non-cooperation within two health information technology projects. The study contributes to project management theory through its combined focus on transactional and relational motives. Further, the study contributes to practice by providing a tool for planning and evaluating cooperation in health Information Technology projects and similar complex multi-stakeholder environments.

  12. A spatial web/agent-based model to support stakeholders' negotiation regarding land development.

    2013-11-15

    Decision making in land management can be greatly enhanced if the perspectives of concerned stakeholders are taken into consideration. This often implies negotiation in order to reach an agreement based on the examination of multiple alternatives. This paper describes a spatial web/agent-based modeling system that was developed to support the negotiation process of stakeholders regarding land development in southern Alberta, Canada. This system integrates a fuzzy analytic hierarchy procedure within an agent-based model in an interactive visualization environment provided through a web interface to facilitate the learning and negotiation of the stakeholders. In the pre-negotiation phase, the stakeholders compare their evaluation criteria using linguistic expressions. Due to the uncertainty and fuzzy nature of such comparisons, a fuzzy Analytic Hierarchy Process is then used to prioritize the criteria. The negotiation starts by a development plan being submitted by a user (stakeholder) through the web interface. An agent called the proposer, which represents the proposer of the plan, receives this plan and starts negotiating with all other agents. The negotiation is conducted in a step-wise manner where the agents change their attitudes by assigning a new set of weights to their criteria. If an agreement is not achieved, a new location for development is proposed by the proposer agent. This process is repeated until a location is found that satisfies all agents to a certain predefined degree. To evaluate the performance of the model, the negotiation was simulated with four agents, one of which being the proposer agent, using two hypothetical development plans. The first plan was selected randomly; the other one was chosen in an area that is of high importance to one of the agents. While the agents managed to achieve an agreement about the location of the land development after three rounds of negotiation in the first scenario, seven rounds were required in the second

  13. The weight of stakeholders on festival management. The case of music festivals in Italy

    2012-03-01

    Full Text Available Even if events can represent important drivers for local development, it is possible to have a genuine economic and social contribution only when the event is undertaken within a paradigm that emphasizes the importance of complex interactions between the event’s proposer and its stakeholders. Inside the event sector, festivals represent a specific sub-field that share time similarities and peculiarities as compared to other typologies. This paper analyzes the Italian context of music festivals and deepens the relationships between the festival organizer and public and private actors using stakeholder management approach. Findings suggest that Italian festivals have a reasonable level of entrepreneurship since the analysis reveals a good predisposition for the use of management practices.

    The Fernald Environmental Management Project has been transporting legacy low-level radioactive waste to the Nevada Test Site for disposal since 1985. Additionally, several records of decision have been issued regarding Fernald Environmental Management Project remediation waste disposal on-site, at the Nevada Test Site, or at a permitted commercial disposal facility. Under the Comprehensive Environmental Response, Compensation, and Liability Act, as amended, once of the criteria that must be evaluated prior to issuance of a record of decision is public acceptance. The Fernald Environmental Management Project has made a concerted effort to gain stakeholder support both locally and in Nevada for these records of decision. The Fernald Environmental Management Project`s approach towards stakeholder interaction can provide a valuable framework for other sites that need to dispose of operations or remediation waste at remote, off-site locations. This approach has also been invaluable in allowing the public to understand the actual effects of waste management incidents.

  17. Attenuating effect of vigorous physical activity on the risk for inherited obesity: a study of 47,691 runners.

    Directory of Open Access Journals (Sweden)

    Paul T Williams

    Full Text Available Physical activity has been shown to attenuate the effect of the FTO polymorphism on body weight, and the heritability of body weight in twin and in family studies. The dose-response relationship between activity and the risk for inherited obesity is not well known, particularly for higher doses of vigorous exercise. Such information is needed to best prescribe an exercise dose for obesity prevention in those at risk due to their family history.We therefore analyzed self-reported usual running distance, body mass index (BMI, waist circumference, and mother's and father's adiposity (1 = lean, 2 = normal, 3 = overweight, and 4 = very overweight from survey data collected on 33,480 male and 14,211 female runners. Age-, education-, and alcohol-adjusted regression analyses were used to estimate the contribution of parental adiposities to the BMI and waist circumferences in runners who ran an average of <3, 3-6, 6-9, ≥ 9 km/day.BMI and waist circumferences of runners who ran <3 km/day were significantly related to their parents adiposity (P<10(-15 and P<10(-11, respectively. These relationships (i.e., kg/m(2 or cm per increment in parental adiposity diminished significantly with increasing running distance for both BMI (inheritance×exercise interaction, males: P<10(-10; females: P<10(-5 and waist circumference (inheritance × exercise interaction, males: P<10(-9; females: P = 0.004. Compared to <3 km/day, the parental contribution to runners who averaged ≥ 9 km/day was diminished by 48% for male BMI, 58% for female BMI, 55% for male waist circumference, and 58% for female waist circumference. These results could not be attributed to self-selection.Exceeding the minimum exercise dose currently recommended for general health benefits (energy equivalent to running 2-3 km/day may substantially diminish the risk for inherited obesity. The results are consistent with other research suggesting the physical activity dose required to prevent unhealthy

    Dolores Sucozhañay

    2014-11-01

    Full Text Available This article aims to analyse the role of library managers as change agent when implementing Library 2.0, using transformational leadership and stakeholder management approaches. To do so, a case study in a Latin American academic library was performed. The experiences acquired for a period of six years were analysed, during which three library managers were involved in managing change. Qualitative data from documents, interviews, and observations were collected, and qualitative analysis methods were used to obtain in-depth understanding of the change process. Results show that lack of transformational leadership and stakeholder management contribute to delayed implementation and limited adoption of innovations. Although library managers recognized the importance of different stakeholders to implement changes, they did not apply systematic and proactive strategies to define and manage them. All in all, library managers should be trained as change agents, with emphasis on transformational leadership and stakeholder management skills.

    Full Text Available Introduction: One Health (OH can be considered a complex emerging policy to resolve health issues at the animal–human and environmental interface. It is expected to drive system changes in terms of new formal and informal institutional and organisational arrangements. This study, using Rift Valley fever (RVF as a zoonotic problem requiring an OH approach, sought to understand the institutionalisation process at national and subnational levels in an early adopting country, Kenya. Materials and methods: Social network analysis methodologies were used. Stakeholder roles and relational data were collected at national and subnational levels in 2012. Key informants from stakeholder organisations were interviewed, guided by a checklist. Public sector animal and public health organisations were interviewed first to identify other stakeholders with whom they had financial, information sharing and joint cooperation relationships. Visualisation of the OH social network and relationships were shown in sociograms and mathematical (degree and centrality characteristics of the network summarised. Results and discussion: Thirty-two and 20 stakeholders relevant to OH were identified at national and subnational levels, respectively. Their roles spanned wildlife, livestock, and public health sectors as well as weather prediction. About 50% of national-level stakeholders had made significant progress on OH institutionalisation to an extent that formal coordination structures (zoonoses disease unit and a technical working group had been created. However, the process had not trickled down to subnational levels although cross-sectoral and sectoral collaborations were identified. The overall binary social network density for the stakeholders showed that 35 and 21% of the possible ties between the RVF and OH stakeholders existed at national and subnational levels, respectively, while public health actors’ collaborations were identified at community/grassroots level

    Public health climate change adaptation planning is an urgent priority requiring stakeholder feedback. The 10 Essential Public Health Services can be applied to adaptation activities. To develop a state health department climate and health adaptation plan as informed by stakeholder feedback. With Centers for Disease Control and Prevention (CDC) funding, the New York State Department of Health (NYSDOH) implemented a 2010-2013 climate and health planning process, including 7 surveys on perceptions and adaptation priorities. New York State Department of Health program managers participated in initial (n = 41, denominator unknown) and follow-up (72.2%) needs assessments. Surveillance system information was collected from 98.1% of surveillance system managers. For adaptation prioritization surveys, participants included 75.4% of NYSDOH leaders; 60.3% of local health departments (LHDs); and 53.7% of other stakeholders representing environmental, governmental, health, community, policy, academic, and business organizations. Interviews were also completed with 38.9% of other stakeholders. In 2011 surveys, 34.1% of state health program directors believed that climate change would impact their program priorities. However, 84.6% of state health surveillance system managers provided ideas for using databases for climate and health monitoring/surveillance. In 2012 surveys, 46.5% of state health leaders agreed they had sufficient information about climate and health compared to 17.1% of LHDs (P = .0046) and 40.9% of other stakeholders (nonsignificant difference). Significantly fewer (P leaders (55.8%) and other stakeholders (68.2%). Stakeholder groups agreed on the 4 highest priority adaptation categories including core public health activities such as surveillance, coordination/collaboration, education, and policy development. Feedback from diverse stakeholders was utilized by NYSDOH to develop its Climate and Health Strategic Map in 2013. The CDC Building Resilience Against

    The literature on impact assessment (HIA) registers the importance of stakeholder participation in the assessment process, but still lacks a model for engaging stakeholders of diverse ethnic, professional and sectorial backgrounds. This paper suggests that the multicultural approach can contribute to HIA through a revision of the generic 5-step HIA model, and its implementation in a metropolitan plan in Southern Israel. The health issue scoped by the stakeholders in the HIA is related to land uses in the vicinity of the national hazardous industry and hazardous waste site. The stakeholders were representatives of the diverse populations at stake, including rural Bedouins and Jewish city dwellers, as well as representatives from the public sector, private sector, non-governmental organizations and academia. The case study revealed that a multicultural stakeholder participation process helps to uncover health issues known to the community which were not addressed in the original plan, and provides local knowledge regarding health conditions that is especially valuable when scientific data is uncertain or absent. It enables diverse stakeholders to prioritize the health issues that will be assessed. The case study also reveals ways in which the model needs revisions and improvements such as in recruitment of diverse participants. This paper presents a multicultural model of HIA and discusses some of the challenges that are faced when HIA is implemented in the context of current decision-making culture. -- Highlights: • We revised the generic HIA model in light of the multicultural approach. • We tested the model in a case study of zoning a hazardous industry site. • Multicultural stakeholder participation uncovers health issues known to communities. • It enables community prioritization of health issues. • We present a model for multicultural stakeholder participation in HIA.

    Climate change as a global problem has specific local effects, which in addition to natural areas also affect social and technical systems. The consequences of climate change will differ concerning the different sectors and regions and can be associated with both risks and opportunities to be. To effectively protect against risks, but to also use opportunities, appropriate adaptation measures are needed. In this context, the Competence Centre on Climate Impacts and Adaptation in the Federal Environmental Agency (KomPass) introduced in 2009 and 2010 a series of stakeholder dialogues that culminated in a cross-thematic and cross-sectoral national conference ''Already adapted?''. The events were part of the research project ''Stakeholder Dialogues: Opportunities and Risks of Climate Change'', conducted by the Institute for Ecological Economy Research (IOeW) in cooperation with the University of Applied Sciences Eberswalde. Some dialogues were held in cooperation with partners from respective associations or authorities. The National Dialogue took place in cooperation with the agency compass orange. The aim of the dialogues was one hand to capture the need for action resulting from climate change, and analyze and develop approaches to adaptation strategies.The different sectors and industries were represented by associations and companies, ministries and authorities and by civil society and academia. On the other hand adaptation needs, demands on the political framework, and research and cooperation needs should be be assessed and analyzed in an interdisciplinary process. From this, KomPass will derive recommendations for the design of the national Action Plan Adaptation and feed into the ongoing process. (orig.)

    2010-08-01

    In order to facilitate stakeholder discussions on how to regulate nanotechnology, the opensource program multicriteria mapping (MCM) was used to structure 26 interviews with stakeholders in the USA. MCM offers a systematic part quantitative, part qualitative approach to clarify why some regulatory options (bans, moratoriums, voluntary measures, etc.) were deemed to be acceptable/unacceptable by various stakeholders and which criteria stakeholders used to evaluate the different regulatory options. Adopting an incremental approach and implementing a new regulatory framework was evaluated as the best options whereas a complete ban and no additional regulation of nanotechnology were found to be the least favorable. Criteria applied differed substantially among stakeholders and included social, ethical, regulatory, environmental, and health issues. Opinions on future regulation seem far less polarized than expected and it seems that stakeholders would welcome a combination of voluntary measures, an incremental approach and forming of a new regulatory framework.

    2015-05-01

    This study evaluates the attitudes and perspectives of different stakeholder groups (agricultural producers, pesticide manufacturers, trading companies, retailers, regulators, food safety authorities, scientists and NGOs) towards the concepts of cumulative and aggregate exposure assessment of pesticides by means of qualitative in-depth interviews (n = 15) and a quantitative stakeholder survey (n = 65). The stakeholders involved generally agreed that the use of chemical pesticides is needed, primarily for meeting the need of feeding the growing world population, while clearly acknowledging the problematic nature of human exposure to pesticide residues. Current monitoring was generally perceived to be adequate, but the timeliness and consistency of monitoring practices across countries were questioned. The concept of cumulative exposure assessment was better understood by stakeholders than the concept of aggregate exposure assessment. Identified pitfalls were data availability, data limitations, sources and ways of dealing with uncertainties, as well as information and training needs. Regulators and food safety authorities were perceived as the stakeholder groups for whom cumulative and aggregate pesticide exposure assessment methods and tools would be most useful and acceptable. Insights obtained from this exploratory study have been integrated in the development of targeted and stakeholder-tailored dissemination and training programmes that were implemented within the EU-FP7 project ACROPOLIS.

    2016-09-01

    To evaluate stakeholders' understanding and opinions of the International Finance Facility for Immunisation (IFFIm); to identify factors affecting funding levels; and to explore the future use of IFFIm. Between July and September 2015, we interviewed 33 individuals from 25 organizations identified as stakeholders in IFFIm. In total 22.5 hours of semi-structured interviews were recorded, transcribed and analysed using a framework method. Stakeholders' understanding of IFFIm's financing mechanism and its outcomes varied and many stakeholders wanted more information. Participants highlighted that the change in the macro-economic environment following the 2008 financial crisis affected national policy in donor countries and subsequently the number of new commitments IFFIm received. Since Gavi is now seen as a successful and mature organization, participants stated that donors prefer to donate directly to Gavi. The pharmaceutical industry valued IFFIm for providing funding stability and flexibility. Other stakeholders valued IFFIm's ability to access funds early and enable Gavi to increase vaccine coverage. Overall, stakeholders thought IFFIm was successful, but they had divergent views about IFFIm's on-going role. Participants listed two issues where bond financing mechanisms may be suitable: emergency preparedness and outcome-based time-limited interventions. The benefit of pledging funds through IFFIm needs to be re-evaluated. There are potential uses for bond financing to raise funds for other global health issues, but these must be carefully considered against criteria to establish effectiveness, with quantifiable pre-defined outcome indicators to evaluate performance.

  19. Effects of methodology and stakeholder disaggregation on ecosystem service valuation

    Directory of Open Access Journals (Sweden)

    Emma G. E. Brooks

    2014-09-01

    Full Text Available Contingent valuation is one of the most commonly used methodologies utilized in ecosystem service valuation, thereby including a participatory approach to many such assessments. However, inclusion of nonmonetary stakeholder priorities is still uncommon in ecosystem service valuations and disaggregation of stakeholders is all but absent from practice. We look at four site-scale wetland ecosystem service valuations from Asia that used nonmonetary participatory stated preference techniques from a range of stakeholders, and compare these prioritizations to those obtained from the largest monetary assessments available globally, the Ecosystem Service Value Database (ESVD. Stakeholder assessment suggests very different priorities to those from monetary assessments, yet priorities between different sites remained broadly consistent. Disaggregation of beneficiaries in one site showed marked differences in values between stakeholders. Monetary values correlate positively with values held by government officers and business owners, but negatively with fishermen and women who are relying most directly on the wetland ecosystem services. Our findings emphasize that ecosystem service assessment, monetary or otherwise, must capture the diversity of values present across stakeholder groups to incorporate site scale management issues, particularly in relation to poverty alleviation.

    Full Text Available RESUMO A multiplicação de espécies como as da planta de urucum tem limitações em função do conhecimento limitado das características morfológicas e fisiológicas das sementes e das plântulas e da restrição de métodos para determinar a qualidade dessas sementes. Nessa pesquisa, o objetivo foi estudar a adequação do teste de envelhecimento acelerado para estimar o vigor das sementes de urucum (Bixa orellana L., relacionando os resultados desse teste com a formação das plântulas e as diferenças de genótipo dos acessos genéticos. As sementes de urucum, representadas por quatro acessos genéticos, e por três lotes, foram avaliadas pelos testes de germinação, primeira contagem da germinação, classificação do vigor das plântulas e emergência das plântulas (total e índice de velocidade. No teste de envelhecimento acelerado foram avaliados a temperatura, de 41 ºC, e os períodos, de 48; 72 e 96 horas, de exposição das sementes às umidades relativas de 100% (água e de 76% (solução saturada de NaCl. A solução saturada reduz a quantidade de água absorvida pelas sementes de urucum, expostas às condições do teste de envelhecimento acelerado, reduzindo a deterioração das sementes, favorecendo a uniformidade dos resultados e a redução da proliferação de fungos, comuns na germinação das sementes de urucum. O teste de envelhecimento acelerado, com água ou solução salina, por 72 horas ou 96 horas, é eficiente para classificar as sementes de urucum quanto à qualidade. Assim, as variações dos teores de água das sementes de urucum devem ser entre 23;6 e 28;9% (72 horas e 29;7 e 32;9% (96 horas para a utilização da água e entre 7,3 e 9,5% para a utilização da solução salina de NaCl.

    Mapping of the with-in field variability of crop vigor has a long tradition with a success rate ranging from medium to high depending on the local conditions of the study. Information about the development of agronomical relevant crop parameters, such as above-ground biomass and crop nutritional status, provides high reliability for yield estimation and recommendation for variable rate application of fertilizers. The aim of this study was to utilize unmanned and satellite multispectral imaging for estimation of basic crop parameters during the growing season. The experimental part of work was carried out in 2014 at the winter wheat field with an area of 69 ha located in the South Moravia region of the Czech Republic. An UAV imaging was done in April 2014 using Sensefly eBee, which was equipped by visible and near infrared (red edge) multispectral cameras. For ground truth calibration the spectral signatures were measured on 20 sites using portable spectroradiometer ASD Handheld 2 and simultaneously plant samples were taken at BBCH 32 (April 2014) and BBCH 59 (Mai 2014) for estimation of above-ground biomass and nitrogen content. The UAV survey was later extended by selected cloud-free Landsat 8 OLI satellite imagery, downloaded from USGS web application Earth Explorer. After standard pre-processing procedures, a set of vegetation indices was calculated from remotely and ground sensed data. As the next step, a correlation analysis was computed among crop vigor parameters and vegetation indices. Both, amount of above-ground biomass and nitrogen content were highly correlated (r > 0.85) with ground spectrometric measurement by ASD Handheld 2 in BBCH 32, especially for narrow band vegetation indices (e.g. Red Edge Inflection Point). UAV and Landsat broadband vegetation indices varied in range of r = 0.5 - 0.7, highest values of the correlation coefficients were obtained for crop biomass by using GNDVI. In all cases results from BBCH 59 vegetation stage showed lower

    Full Text Available Seed procyanidin composition of Vitis vinifera L. var. ˈCarignanˈ and ˈGrenacheˈ was analyzed to assess the impact of vintage climatology, plant vigor and bunch variability on the quality of grapes. This study was carried out over 2007 and 2008 vintages in Terra Alta denomination of origin (DO. This region is located in northeastern Spain and characterized by a Mediterranean climate with a continental tendency. Procyanidin composition of seeds from four vineyards was analyzed by rapid resolution liquid chromatography (RRLC-DAD-TOF/MS. Vintage, vigor and ripeness uniformity had an influence on the procyanidin concentration in seeds. Flavan-3-ol polymerization increased during the warm year, together with a notable dependence on the variety and vine vigor. In warmer years and low vigor, ˈGrenacheˈ seed composition is likely to be more vulnerable than ˈCarignanˈ. High levels of flavan-3-ol monomers and low polymerization characterized the seeds of the temperate year.

    2015-03-01

    Impacts of explosive volcanic eruptions on civil aviation were reconsidered after the 2010 Eyjafjallajökull eruption in Iceland, which caused unprecedented disruptions of air traffic operations in Europe. During and after the aviation breakdown of April-May 2010, communication between the involved stakeholders was recognized as a major concern. Due to the complexity and multidisciplinary nature of the topic, a great number of actors are involved, which often have little interaction outside these exceptional events. In this work, we aim at identifying the relationships between the stakeholders involved in aviation management during eruptions, as well as their needs and priorities. We perform an anonymous on-line survey, focused mainly on the use of tephra dispersal models for civil aviation purposes. We collect feedback on recent developments including our current impact assessment research, which produced a GIS-based software tool to estimate impacts on aviation based on tephra dispersal forecasts. Answers allow identifying stakeholders' requirements on ash dispersal forecasts and their use for aviation management purposes. We underline the main differences between three homogeneous groups (aviation managers and employees, modellers and field scientists, other stakeholders) and identify main end-user requirements for developing tools similar to ours. This work provides useful insights for the development of tools to support aviation stakeholders during volcanic eruptions.

The agro-ecosystem analysis included biophysical processes at microcatchment scale and the stakeholders’ perceptions, interests and practices related to the nitrate issue (stakeholders analysis. The conceptual SLIM framework model supported new interactions among stakeholders, that were facilitated by researchers, using dialogical tools to enable them to use scientific data and to integrate their own knowledge on the farming system.

The stakeholder analysis contributed to the identification of priorities both for scientific research and agro-environment policies. Researchers provided the site-specific scientific knowledge, in a way that enabled stakeholders to identify the relationships between agricultural practices, landscape values and the nitrate pollution issue and to elaborate shared strategies to develop concerted actions. New spaces for interaction between researchers and stakeholders should be created to face complex agro-environment issues at catchment scale, such as the nitrate pollution of groundwater. The implication for agronomy research is that the experiments should be designed to produce suitable results to facilitate participatory sessions and that it is worthwhile to invest in specific skills of communication science and group dynamics management within the agronomy researchers’ community, in order to integrate agronomy knowledge into high quality participatory processes.

    This study assesses data management needs in clinical research from the perspectives of researchers, software analysts and developers. This is a mixed-methods study that employs sublanguage analysis in an innovative manner to link the assessments. We performed content analysis using sublanguage theory on transcribed interviews conducted with researchers at four universities. A business analyst independently extracted potential software features from the transcriptions, which were translated into the sublanguage. This common sublanguage was then used to create survey questions for researchers, analysts and developers about the desirability and difficulty of features. Results were synthesized using the common sublanguage to compare stakeholder perceptions with the original content analysis. Individual researchers exhibited significant diversity of perspectives that did not correlate by role or site. Researchers had mixed feelings about their technologies, and sought improvements in integration, interoperability and interaction as well as engaging with study participants. Researchers and analysts agreed that data integration has higher desirability and mobile technology has lower desirability but disagreed on the desirability of data validation rules. Developers agreed that data integration and validation are the most difficult to implement. Researchers perceive tasks related to study execution, analysis and quality control as highly strategic, in contrast with tactical tasks related to data manipulation. Researchers have only partial technologic support for analysis and quality control, and poor support for study execution. Software for data integration and validation appears critical to support clinical research, but may be expensive to implement. Features to support study workflow, collaboration and engagement have been underappreciated, but may prove to be easy successes. Software developers should consider the strategic goals of researchers with regard to the

    Full Text Available Abstract Background People living in neighbourhoods of lower socioeconomic status have been shown to have higher rates of obesity and a lower likelihood of meeting physical activity recommendations than their more affluent counterparts. This study examines the sociospatial distribution of access to facilities for moderate or vigorous intensity physical activity in Scotland and whether such access differs by the mode of transport available and by Urban Rural Classification. Methods A database of all fixed physical activity facilities was obtained from the national agency for sport in Scotland. Facilities were categorised into light, moderate and vigorous intensity activity groupings before being mapped. Transport networks were created to assess the number of each type of facility accessible from the population weighted centroid of each small area in Scotland on foot, by bicycle, by car and by bus. Multilevel modelling was used to investigate the distribution of the number of accessible facilities by small area deprivation within urban, small town and rural areas separately, adjusting for population size and local authority. Results Prior to adjustment for Urban Rural Classification and local authority, the median number of accessible facilities for moderate or vigorous intensity activity increased with increasing deprivation from the most affluent or second most affluent quintile to the most deprived for all modes of transport. However, after adjustment, the modelling results suggest that those in more affluent areas have significantly higher access to moderate and vigorous intensity facilities by car than those living in more deprived areas. Conclusions The sociospatial distributions of access to facilities for both moderate intensity and vigorous intensity physical activity were similar. However, the results suggest that those living in the most affluent neighbourhoods have poorer access to facilities of either type that can be reached on foot

    To characterize metabolic features of women with polycystic ovary syndrome (PCOS) by exercise behavior and determine relative health benefits of different exercise intensities. Cross-sectional study. Tertiary academic institution. Three hundred and twenty-six women aged 14-52 years-old with PCOS by Rotterdam criteria examined between 2006 and 2013. International Physical Activity Questionnaire (IPAQ) administered to classify patients into three groups based on Department of Health and Human Services (DHHS) Guidelines of vigorous, moderate, and inactive, along with physical examination and serum testing. Blood pressure, body mass index (BMI), waist circumference, fasting lipids, fasting glucose and insulin, 2-hour 75-gram oral glucose tolerance, homeostatic model assessment of insulin resistance (HOMA-IR). The DHHS guidelines for adequate physical activity were met by 182 (56%) women. Compared with moderate exercisers and inactive women, the vigorous exercisers had lower BMI and lower HOMA-IR; higher levels of high-density lipoprotein cholesterol and sex hormone-binding globulin; and a reduced prevalence of the metabolic syndrome. In a multivariate logistic regression analysis controlling for age, BMI, and total energy expenditure, every hour of vigorous exercise reduced a patient's odds of metabolic syndrome by 22% (odds ratio 0.78; 95% confidence interval, 0.62, 0.99). Women with PCOS who met DHHS guidelines for exercise demonstrated superior metabolic health parameters. Vigorous but not moderate activity is associated with reduced odds of the metabolic syndrome, independent of age, BMI, and total energy expenditure. PCOS patients should be encouraged to meet activity guidelines via vigorous physical activity. Copyright © 2016 American Society for Reproductive Medicine. Published by Elsevier Inc.

    We examined the influence of vigorous physical activity (VPA) bout frequency on bone strength accrual across adolescence, independent of total volume of VPA. We measured VPA (6 metabolic equivalents; total volume and bout frequency 18 y) over a maximum of 4 years. We applied finite element analysis to high-resolution peripheral quantitative computed tomography scans of the distal tibia (8% site) to estimate bone strength (failure load; F.Load, Newtons). We fit a mixed effects model with maturity offset (years from age at peak height velocity) as a random effect and sex, ethnicity, tibia length, lean body mass, and VPA (volume and bout frequency) as fixed effects. VPA volume and bout frequency were positively associated with F.Load across adolescence; however, VPA volume did not predict F.Load once VPA bout frequency was included in the model. Participants in the upper quartile of VPA bout frequency (∼33 bouts per day) had 10% (500 N) greater F.Load across adolescence compared with participants in the lowest quartile (∼9 bouts per day; P = .012). Each additional daily bout of VPA was associated with 21 N greater F.Load, independent of total volume of VPA. Frequent VPA should be promoted for optimal bone strength accrual.

    Little is known about the physical activity of adolescents born prematurely. This study aimed to: 1) describe relationships between moderate to vigorous physical activity (MVPA) in adolescents born prematurely and various factors and, 2) compare their MVPA level to guidelines. A secondary analysis was performed using data from 64 adolescents (16.1 ± 2.5 years old, born £29 weeks gestation; 57.8% girls). Time spent in MVPA was based on accelerometry data. Sociodemographic, prematurity and comorbidity variables were based on questionnaire data or, for movement difficulty, from the results of the Movement Assessment Battery for Children-Second Edition. Multiple regression analysis showed that participants who were older (b = -4.52, p < .001), female (b = 14.18, p = .014), with movement difficulty (b = 18.64, p = .014), with health problems (b = 11.78, p = .036) and without hyperactive behavior (trend, b = 2.04, p = .099) spent less time in MVPA. Together these variables explained 44.4% of the variance in MVPA. Most participants (79.7%) did not meet Canadian MVPA guidelines. Study results suggest that physical activity interventions should especially target adolescents born prematurely who are older, female, with health problems, and with marked movement difficulties.

    Full Text Available The purpose of this study was to establish step-count guidelines for sixth-grade students and assess the ability of step-counts to discriminate between students achieving and not achieving 60-minutes of moderate to vigorous physical activity daily. 201 sixth-grade students completed the study. They wore a pedometer and an accelerometer at the waist level for one full day. ROC curves were used to establish step-count guidelines and determine the diagnostic accuracy of step-counts. Sixth grade students need 12,118 steps/day to reach adequate daily levels of physical activity. The AUC indicated good diagnostic accuracy of step-counts. Suggested step-count guidelines can be a useful tool for identifying children who need to increase their daily levels of physical activity. The step-count cutoff proposed in this study is adequate for discriminating between sixth grade students reaching and not reaching recommended levels of physical activity.

    Full Text Available ABSTRACTThis study aimed to evaluate the influence of foliar fertilizer doses containing Mn of phenological stages of suggested application in RR soybeans, to recover management damages with glyphosate at postemergence application on seed vigor in post-harvest and post six months storage. The seeds originated from a field experiment conducted , which included two applications of glyphosate, concomitant with foliar fertilizer in growth stages V4 and V6, with 0.00, 113.50 and 227.00 mg ha-1doses of Mn2+. Germination, GSI (Germination Speed Index, electrical conductivity tests and the first count of seeds were conducted. The application of Mn did not affect the physiological quality of RR soy in postharvest. However, in post-storage, higher doses of Mn had a negative effect on tests of abnormal seedlings, GSI and electrical conductivity. The applications of Mn, regardless of the developmental stage, did not interfere in the germination and first count tests, with and without storage. The electrical conductivity test showed a higher correlation with the seed germination test in the post-harvest treatment.

    Exercise has been recommended for enhancing sleep; a claim linked to the belief that sleep need - defined by sleep duration and depth - is increased post-exercise to allow tissue recovery. Objective studies investigating exercise-sleep responses have produced mixed outcomes, and the disparity in results between studies may be due to differences in individual characteristics and/or exercise protocol, emphasising the importance of carefully controlled trials. We investigated the role of exercise on the sleep need of sedentary adults, after controlling for exercise mode, timing and duration. Twelve healthy volunteers (25.2 ± 4.0 years, 9 females, [Vdot]O(2)max 35.4 ± 8.8 ml· kg(-1) · min(-1)) were randomised to no-exercise or to a bout of treadmill exercise at 45%, 55%, 65% or 75% [Vdot]O(2)max in a crossover design. Sleep on no-exercise and exercise nights were assessed by polysomnography. Participants spent a greater proportion of sleep in light sleep (stage 1 + stage 2) after exercise at both 65% and 75% [Vdot]O(2)max (P exercise condition. There was a trend of a reduced proportion of rapid eye movement sleep with increased exercise intensity (P = 0.067). No other changes were observed in any other sleep variables. Two findings emerged: vigorous exercise did not increase sleep need; however, this level of exercise increased light sleep.

    Seed size, interior abnormal and damage of the tomato seeds will affect the germination. The purpose of this paper was to study the relationship between the internal morphology, seed size and seed germination of tomato. The preprocessing algorithm of X-ray image of tomato seeds was studied, and the internal structure characteristics of tomato seeds were extracted by image processing algorithm. By developing the image processing software, the cavity area between embryo and endosperm and the whole seed zone were determined. According to the difference of area of embryo and endosperm and Internal structural condition, seeds were divided into six categories, Respectively for three kinds of tomato seed germination test, the relationship between seed vigor and seed size , internal free cavity was explored through germination experiment. Through seedling evaluation test found that X-ray image analysis provide a perfect view of the inside part of the seed and seed morphology research methods. The larger the area of the endosperm and the embryo, the greater the probability of healthy seedlings sprout from the same size seeds. Mechanical damage adversely effects on seed germination, deterioration of tissue prone to produce week seedlings and abnormal seedlings.

    Full Text Available Seed treatment is a low-cost and efficacious method to deliver a diversity of compounds to field crops. This study evaluated the uptake of seed-applied Cu by maize and the effect on seed vigor. The treatments were composed of a control (untreated seeds and five dosages of Cu: 0.11, 0.22, 0.44, 0.88 and 1.76 mg Cu seed–1, applied as cuprous oxide and copper oxychloride formulations. Seedling emergence and the speed of seedling emergence were determined in three periods: 1, 60 and 120 days after Cu application. Evaluations of root and shoot dry mass, Cu tissue concentration and efficiencies of Cu uptake and incorporation were conducted with two-leaf stage maize plants. Seed-applied Cu reduces the speed of maize seedling emergence, while the final emergence percentage is not affected. Shoot dry mass tends to increase with the application of Cu, while there is no interference on root dry mass within the dosages tested. Cu tissue concentration of both roots and shoots increases as higher dosages of Cu are applied to seeds, with higher accumulation in roots. Cuprous oxide promotes higher uptake of Cu by maize roots compared to copper oxychloride.

    The clustering of metabolic syndrome risk factors is inversely related to the amount of physical activity. However, the question remains as to how much daily physical activity is enough to prevent the onset of metabolic disorders in adolescents? Therefore, the objectives of this study were to associate the metabolic risk score with the moderate to vigorous physical activity (MVPA) and to identify the amount of daily physical activity to prevent the onset of the metabolic risk factors in Brazilian adolescents. The study involved 391 participants aged 10 to 18 years. Physical activity was measured by accelerometry. The counts obtained in the different activities were transformed into metabolic equivalents and classified as light (≥ 1.5 but activities. The continuous risk score for metabolic syndrome was calculated using the following risk factors: waist circumference, blood pressure, blood glucose, HDL-C and triglycerides. Time spent in MVPA was inversely associated with the continuous risk score for metabolic syndrome (p physical activity relates to metabolic syndrome in adolescents. This population should be encouraged to gradually replace part of their sedentary time with physical activities.

    Associations of metabolic syndrome (MetS) with lifestyle behaviors in youth is potentially important for identifying subgroups at risk and encourage interventions. This study evaluates the associations among the clustering of metabolic risk factors and moderate-to-vigorous physical activity (MVPA) in youth. The sample comprised 522 girls and 402 boys (N = 924) aged 11 to 17 years. Height, weight, waist circumference (WC), fasting glucose, high-density lipoprotein cholesterol, triglycerides, and blood pressures were measured. Cardiorespiratory fitness (CRF) was assessed using the 20-m shuttle run test. MVPA was estimated with a 3-day diary. Outcome variables were statistically normalized and expressed as z scores. A clustered metabolic risk score was computed as the mean of z scores. Multiple linear regression was used to test associations between metabolic risk and MVPA by sex, adjusted for age, WC, and CRF. After adjustment for potential confounders, MVPA was inversely associated with the clustering of metabolic risk factors in girls, but not in boys; in addition, after adjusting for WC, the statistical model of that relationship was substantially improved in girls. MVPA was independently associated with increased risk of MetS in girls. Additional efforts are needed to encourage research with different analytical approach and standardization of criteria for MetS in youth.

    Polydopamine (PDA) coating provides a promising approach for immobilization of biomolecules onto almost all kinds of solid substrates. However, the deposition kinetics of PDA coating as a function of temperature and reaction method is not well elucidated. Since dopamine self-polymerization usually takes a long time, therefore, rapid-formation of PDA film becomes imperative for surface modification of biomaterials and medical devices. In the present study, a practical method for preparation of rapidly-deposited PDA coating was developed using a uniquely designed device, and the kinetics of dopamine self-polymerization was investigated by QCM sensor system. It was found that high temperature and vigorous stirring could dramatically speed up the formation of PDA film on QCM chip surface. Surface characterization, BSA binding study, cell viability assay and antibacterial test demonstrates that the polydopamine coating after polymerization for 30 min by our approach exhibits similar properties to those of 24 h counterpart. The method has a great potential for rapid-deposition of polydopamine films to modify biomaterial surfaces. PMID:25415328

    The instability and accelerated melting of the Antarctic Ice Sheet are among the foremost elements of contemporary global climate change. The increased freshwater output from Antarctica is important in determining sea level rise, the fate of Antarctic sea ice and its effect on the Earth’s albedo, ongoing changes in global deep-ocean ventilation, and the evolution of Southern Ocean ecosystems and carbon cycling. A key uncertainty in assessing and predicting the impacts of Antarctic Ice Sheet melting concerns the vertical distribution of the exported meltwater. This is usually represented by climate-scale models as a near-surface freshwater input to the ocean, yet measurements around Antarctica reveal the meltwater to be concentrated at deeper levels. Here we use observations of the turbulent properties of the meltwater outflows from beneath a rapidly melting Antarctic ice shelf to identify the mechanism responsible for the depth of the meltwater. We show that the initial ascent of the meltwater outflow from the ice shelf cavity triggers a centrifugal overturning instability that grows by extracting kinetic energy from the lateral shear of the background oceanic flow. The instability promotes vigorous lateral export, rapid dilution by turbulent mixing, and finally settling of meltwater at depth. We use an idealized ocean circulation model to show that this mechanism is relevant to a broad spectrum of Antarctic ice shelves. Our findings demonstrate that the mechanism producing meltwater at depth is a dynamically robust feature of Antarctic melting that should be incorporated into climate-scale models.

    Examined patterns and determinants of objectively measured moderate-to-vigorous physical activity (MVPA) over 4 years in US emerging adults. Waves 1 through 4 (W1 [10th grade] to W4 data of a national cohort starting in 2010 (N = 561; 16.19 ± 0.51 years) were used. MVPA was assessed annually from accelerometers; BMI calculated from measured height/weight; and surveys ascertained self-reported physical activity (PA) planning, peer PA , family support, W1 sociodemographics, W4 school status, W4 residence, and W4 employment. Latent growth modeling estimated trajectories in log-transformed duration (minutes/day) of MVPA and associations with covariates. Less than 9% of participants met the recommended 60+ minutes/day MVPA across W1 through W4. W1 MVPA was greater in males versus females (B = 0.46, P planning (W1-W3: B = 0.10, B = 0.06, B = 0.08, Ps college versus not-attending school (B = 0.52, P college students living on campus versus at home (B = 0.37, P High-school students engaged in little MVPA and maintained this low level through the transition to adulthood. Emerging adults' MVPA engagement may vary according to social contexts. Those with high BMI may benefit most from interventions to promote MVPA.

    Brain metastasis occurs in 10-15% of metastatic breast cancer patients and is associated with poor prognosis. This study aims to identify tumor characteristics of primary breast cancer, which are related to brain metastases in Hong Kong Chinese patients. A retrospective study of patients with invasive breast cancer receiving treatment in a university hospital from January 2001 to December 2008 was performed. The clinicopathological factors of patients with brain metastases were analyzed and compared with those who had no brain metastasis. Risk factors for brain metastasis were identified by univariate analysis first and then by multivariate analysis. A total of 912 patients with invasive breast cancer were treated during the study period. Of these, 30 patients were found to have distant metastases to brain. Patients with brain metastases had more breast tumors of higher histological grade (Grade III, 78.9% vs. 30.2%; p = 0.001). Their tumors also had a significantly higher rate of negative estrogen receptors (78.9% vs. 30.2%, p = 0.001). On multivariate analysis, only high tumor grading was found to be predictive of developing brain metastasis. Chinese breast cancer patients with brain metastasis were more likely to have high-grade tumors and negative estrogen receptor status. A more vigorous surveillance program for the central nervous system should be considered for this group of patients. Copyright © 2015. Published by Elsevier Taiwan.

    To determine if an existing ballroom dance classroom program meets national recommendations to engage children in moderate to vigorous physical activity (MVPA) for ≥50% of class time and to determine class effects on body mass index (BMI). Prospective descriptive study. Setting . Two New York City public schools. Seventy-nine fourth and fifth grade students. The System for Observing Fitness Instruction Time (SOFIT) and direct heart rate monitoring were used to determine participants' MVPA levels during class time. Weight and height were measured to calculate BMI. Means were calculated for continuous variables; frequency counts and percentages were calculated for categorical variables. Change in BMI percentiles was assessed by using Bhapkar's χ(2) test of overall marginal homogeneity. Data from SOFIT observations showed that a mean of 50.0% and 67.0% of class time in the first and second halves of the program, respectively, were spent in MVPA. Data from the heart rate monitoring revealed that 71.1% of students were at ≥25% heart rate reserve, which indicated MVPA for ≥50% of class time. Improvement was seen in BMI percentile (p= .051). Ballroom dance provides MVPA in elementary school children for ≥50% of class time and has a positive impact on BMI percentiles.

    Purpose: Habitual action is an important aspect of health behaviour, but the relevance of various habit strength indicators continues to be debated. This study focused specifically on moderate-to-vigorous physical activity (MVPA) and evaluated the construct validity of a framework emphasizing patterned action, stimulus-response bonding, automaticity, and negative consequences for nonperformance as indicators of habit strength for this form of exercise. Methods: Upper-level undergraduates (N = 124) provided demographic information and responded to questionnaire items assessing historical MVPA involvement, current MVPA involvement, and the four proposed habit strength dimensions. Factor analyses were used to examine the latent structure of the habit strength indicators, and the model's construct validity was evaluated via an examination of relationships with repetition history and current behaviour. Results: At a measurement level, findings indicated that the proposed four-component model possessed psychometric integrity as a coherent set of factors. Criterion-related validity was also demonstrated via significant changes in three of the four factors as a function of past involvement in MVPA and significant correlations with the frequency, duration, and intensity of current MVPA. Conclusions: These findings support the construct validity of this exercise habit strength model and suggest that it could provide a template for future research on how MVPA habits are developed and maintained.

    Full Text Available BACKGROUND: Sedentary behavior has emerged as a novel health risk factor independent of moderate to vigorous physical activity (MVPA. Previous studies have shown self-reported sedentary time to be associated with mortality; however, no studies have investigated the effect of objectively measured sedentary time on mortality independent of MVPA. The objective our study was to examine the association between objectively measured sedentary time and all-cause mortality. METHODS: 7-day accelerometry data of 1906 participants aged 50 and over from the U.S. nationally representative National Health and Nutrition Examination Survey (NHANES 2003-2004 were analyzed. All-cause mortality was assessed from the date of examination through December 31, 2006. RESULTS: Over an average follow-up of 2.8 years, there were 145 deaths reported. In a model adjusted for sociodemographic factors, lifestyle factors, multiple morbidities, mobility limitation, and MVPA, participants in third quartile (hazard ratio (HR:4.05; 95%CI:1.55-10.60 and fourth quartile (HR:5.94; 95%CI: 2.49-14.15 of having higher percent sedentary time had a significantly increased risk of death compared to those in the lowest quartile. CONCLUSIONS: Our study suggests that sedentary behavior is a risk factor for mortality independent of MVPA. Further investigation, including studies with longer follow-up, is needed to address the health consequences of sedentary behavior.

  16. The Effect of Vigorous- Versus Moderate-Intensity Aerobic Exercise on Insulin Action.

    Due to the beneficial effects on a wide range of modern medical conditions, most professional societies recommend regular aerobic exercise as part of a healthy lifestyle. Many of the exercise-related health benefits exhibit a dose-response relationship: Up to a point, more exercise is more beneficial. However, recent studies have suggested that different exercise intensities may provide distinct health benefits, independent of energy expenditure (i.e., exercise dose). One of these benefits, primarily mediated by the skeletal muscle, is exercise-related changes in insulin action and glucose homeostasis. Glucose uptake in the exercising muscle occurs through insulin-independent mechanisms whose downstream signaling events ultimately converge with insulin-signaling pathways, a fact that may explain why exercise and insulin have additive effect on skeletal muscle glucose uptake. Although the existing evidence is somewhat conflicting, well-controlled randomized studies suggest that, when controlled for total energy expenditure, moderate-intensity aerobic exercise improves insulin sensitivity more than vigorous-intensity aerobic exercise. The mechanisms underlying this difference are largely unknown. One possible explanation involves enhanced metabolism of fatty acid stores in the skeletal muscle by moderate-intensity exercise, which may directly improve insulin sensitivity. Overall, new technologic and physiologic investigative tools are beginning to shed light on the biology. Further understanding of these mechanisms will lead to better understanding of the clinical implications of a healthy lifestyle and may ultimately offer new therapeutic targets for common medical conditions such as insulin resistance and diabetes.

    Chronic exercise has been shown to alter plasma lipids in man and animals, but the mechanism(s) responsible for this phenomenon have not been clarified. In the present study we have examined the role of the liver in the production of lipoproteins following an intensive exercise regimen in lean and obese Zucker rats. Four-week-old lean and obese male Zucker rats were subjected to a vigorous exercise regimen of running on a motor-driven treadmill for 10 weeks. Hepatic lipoprotein cholesterol production was then assessed using liver perfusion techniques. Plasma cholesterol concentration was significantly lower in both lean and obese runners versus appropriate non-exercised controls. This decrease was due to a decline in both chylomicron and HDL cholesterol. Exercise had no affect on plasma VLDL and LDL cholesterol concentrations. Hepatic VLDL cholesterol production was elevated in obese rats versus lean rats and was not affected by exercise in runners of either phenotype. Hepatic HDL cholesterol production was higher in lean runners but was unchanged in obese runners. Plasma triglyceride was reduced by 50% in exercised obese rats. In summary, intense exercise decreased plasma triglyceride, cholesterol, and HDL cholesterol concentrations in lean and obese Zucker rats. Since hepatic HDL cholesterol production was increased and hepatic VLDL cholesterol production was unaffected by exercise, the changes in plasma lipid levels observed following exercise appear to be mediated by extrahepatic mechanisms.

    2017-11-01

    Full Text Available Understanding the food-energy-water nexus is necessary to identify risks and inform strategies for nexus governance to support resilient, secure, and sustainable societies. To manage risks and realize efficiencies, we must understand not only how these systems are physically connected but also how they are institutionally linked. It is important to understand how actors who make planning, management, and policy decisions understand the relationships among components of the systems. Our question is: How do stakeholders involved in food, energy, and water governance in Phoenix, Arizona understand the nexus and what are the implications for integrated nexus governance? We employ a case study design, generate qualitative data through focus groups and interviews, and conduct a content analysis. While stakeholders in the Phoenix area who are actively engaged in food, energy, and water systems governance appreciate the rationale for nexus thinking, they recognize practical limitations to implementing these concepts. Concept maps of nexus interactions provide one view of system interconnections that be used to complement other ways of knowing the nexus, such as physical infrastructure system diagrams or actor-networks. Stakeholders believe nexus governance could be improved through awareness and education, consensus and collaboration, transparency, economic incentives, working across scales, and incremental reforms.

    Full Text Available The present work had as objective to verify the effect of treatment with fungicide on the germination and vigor of four lots of clove basil seeds, submitted to the traditional aging and with saturated salt solution, for periods of 36, 48, 60 and 72 hours, at 42ºC. After these periods, the seeds were evaluated by the germination test, using the first count of the number of normal seedlings as vigor indicative. The vigor and the germination of the seeds decreased as increased the time of aging. In the use of saturated salt solution, the seeds water content was lower and more uniform. The fungicide treatment increased the percentage average of germination, without provoking significant modifications in the contrasts among the lots. The periods of 36 and 48 hours were efficient in evaluating of the physiologic quality of the clove basil seeds.O presente trabalho teve como objetivo verificar o efeito do período de exposição, tipos de solução e tratamento com fungicida sobre a germinação e o vigor de quatro lotes de sementes de alfavaca-cravo, submetidas ao teste de envelhecimento acelerado tradicional e com uso de solução saturada de NaCl, por períodos de 36, 48, 60 e 72 horas na temperatura de 42ºC. Após estes períodos, as sementes foram avaliadas pelo teste de germinação, utilizando-se a primeira contagem do teste de germinação como indicativo de vigor. Tanto o vigor quanto a germinação das sementes analisadas, diminuíram conforme se aumentou o tempo de envelhecimento. Na utilização de solução salina, o teor e a variabilidade de água das sementes foram menores. O tratamento fungicida aumentou a média percentual de germinação, mas não provocou modificações acentuadas nos contrastes entre os lotes.

    The talk addresses the feasibility and difficulties of research projects to reach out and to integrate a sufficient number of stakeholders (vgl. Carrada, 2006; Poulsen, 2007; Zikos et al. 2012; Lee & Belohlav, 2014). With "stakeholders" we understand end-users, policy makers, students for capacity building, administrators and interested general public. The design and later the implementation of stakeholder integration and public engagement strongly depend on the priority-setting and requirements of funding agencies (EU [1], DFG, BMBF and the regional ministries in Germany). They affect the size and constellation of consortia as well as the longevity and continuity of research community; on the other hand they also determine the weighting of communication, dissemination, outreach (and networking) activities within the project. For instance by public engagement of EU funded projects a share of 10% for communication and outreach activities was rated as best practices in 2014 [2]. On the national level there is no such appointment so far. In our talk we will quantify and compare activities among selected EU and nationally funded collaborative projects in Germany, address the hurdles, investigate the communication tools, examine the outreach channels and dissemination tactics, reflect the performances and the results achieved so far, with the objective to answer the following questions: - What tools/channels have been applied so far? Were they efficient and expedient? - What can be count as best practices? - Are such activities sustainable at all? The goal of this talk is to show the complexity of the stakeholder integration and public engagement in research projects, to critically assess our experiences gained in past and running projects, and to subsequently have an interactive exchange with other project professionals at EGU.

    The National Wildlife Refuge System, managed by the U.S. Fish and Wildlife Service (FWS), is the largest system of public lands in the world dedicated to wildlife conservation. There are over 545 national wildlife refuges nationwide, encompassing 95 million acres. As part of the National Wildlife Refuge System Improvement Act of 1997, each refuge is developing 15-year comprehensive conservation plans (CCPs). Each CCP describes a vision and desired future condition for the refuge and outlines goals, objectives, and management strategies for each refuge's habitat and visitor service programs. The CCP process for Canaan Valley National Wildlife Refuge (Refuge) in Davis, West Virginia was initiated in 2006. This planning process provides a unique opportunity for public input and involvement. Public involvement is an important part of the CCP process. Participation by parties with a stake in the resource (stakeholders) has the potential to increase understanding and support and reduce conflicts. Additionally, meaningful public participation in a decision process may increase trust and provide satisfaction in terms of both process and outcome for management and the public. Public meetings are a common way to obtain input from community members, visitors, and potential visitors. An 'Issues Workbook' is another tool the FWS uses to obtain public input and participation early in the planning process. Sometimes, however, these traditional methods do not capture the full range of perspectives that exist. A stakeholder evaluation is a way to more fully understand community preferences and opinions related to key topics in refuge planning. It can also help refuge staff understand how changes in management affect individuals in terms of their preference for services and experiences. Secondarily, a process such as this can address 'social goals' such as fostering trust in regulating agencies and reducing conflict among stakeholders. As part of the CCP planning effort at Canaan

    Despite the emergence of genomics-based risk prediction tools in oncology, there is not yet an established framework for communication of test results to cancer patients to support shared decision-making. We report findings from a stakeholder engagement program that aimed to develop a framework for using Markov models with individualized model inputs, including genomics-based estimates of cancer recurrence probability, to generate personalized decision aids for prostate cancer patients faced with radiation therapy treatment decisions after prostatectomy. We engaged a total of 22 stakeholders, including: prostate cancer patients, urological surgeons, radiation oncologists, genomic testing industry representatives, and biomedical informatics faculty. Slides were at each meeting to provide background information regarding the analytical framework. Participants were invited to provide feedback during the meeting, including revising the overall project aims. Stakeholder meeting content was reviewed and summarized by stakeholder group and by theme. The majority of stakeholder suggestions focused on aspects of decision aid design and formatting. Stakeholders were enthusiastic about the potential value of using decision analysis modeling with personalized model inputs for cancer recurrence risk, as well as competing risks from age and comorbidities, to generate a patient-centered tool to assist decision-making. Stakeholders did not view privacy considerations as a major barrier to the proposed decision aid program. A common theme was that decision aids should be portable across multiple platforms (electronic and paper), should allow for interaction by the user to adjust model inputs iteratively, and available to patients both before and during consult appointments.

    2012-05-01

    To investigate stakeholder involvement by Health Technology Assessment Organisations (HTAOs) in France, Spain, England and Wales, Germany, Sweden, and The Netherlands and to examine whether this involvement depends on (i) the administrative tradition and the relevant conception of the relationship between state and society (contractarian and corporative vs. organic), (ii) the general structure of the healthcare system (HCS) (Bismarckian vs. Beveridgian system), and (iii) the role of Health Technology Assessment (HTA) and HTAOs in the HCS. Given the exploratory nature of the study, we considered interviews based on semi-structured questionnaires the most appropriate data-gathering technique. The interviews were administered to 16 key personnel in the HTAOs concerned. We have also carried out a literature review on HTAOs and stakeholders (1999-2011) using PubMed, Ebsco, JSTOR and Wiley Science. In contractarian and (to a lesser extent) Bismarckian models, stakeholders are more involved. The administrative tradition and the HCS appear less important when the HTA is binding and used for regulatory purposes. In such situations, stakeholders are more intensively involved because their participation provides an opportunity for HTAOs to achieve consensus and legitimacy in advance. Despite the limitations of the research (we did not conduct multiple interviews for each HTAO, and key informants were not always available) and its exploratory nature, we can conclude that models of stakeholders involvement cannot easily be transferred from one country to another due to the importance of national administrative traditions and the characteristics of HCSs.

    This study identifies the stakeholders who have a role in medical device purchasing within the wider system of health-care delivery and reports on their particular challenges to promote patient safety during purchasing decisions. Data was collected through observational work, participatory workshops, and semi-structured qualitative interviews, which were analyzed and coded. The study takes a systems-based and engineering design approach to the study. Five hospitals took part in this study, and the participants included maintenance, training, clinical end-users, finance, and risk departments. The main stakeholders for purchasing were identified to be staff from clinical engineering (Maintenance), device users (Clinical), device trainers (Training), and clinical governance for analyzing incidents involving devices (Risk). These stakeholders display varied characteristics in terms of interpretation of their own roles, competencies for selecting devices, awareness and use of resources for purchasing devices, and attitudes toward the purchasing process. The role of "clinical engineering" is seen by these stakeholders to be critical in mediating between training, technical, and financial stakeholders but not always recognized in practice. The findings show that many device purchasing decisions are tackled in isolation, which is not optimal for decisions requiring knowledge that is currently distributed among different people within different departments. The challenges expressed relate to the wider system of care and equipment management, calling for a more systemic view of purchasing for medical devices.

  8. A Framework for Multi-Stakeholder Decision-Making and ...

    Science.gov (United States)

    This contribution describes the implementation of the conditional-value-at-risk (CVaR) metric to create a general multi-stakeholder decision-making framework. It is observed that stakeholder dissatisfactions (distance to their individual ideal solutions) can be interpreted as random variables. We thus shape the dissatisfaction distribution and find an optimal compromise solution by solving a CVaR minimization problem parameterized in the probability level. This enables us to generalize multi-stakeholder settings previously proposed in the literature that minimizes average and worst-case dissatisfactions. We use the concept of the CVaR norm to give a geometric interpretation to this problem and use the properties of this norm to prove that the CVaR minimization problem yields Pareto optimal solutions for any choice of the probability level. We discuss a broad range of potential applications of the framework. We demonstrate the framework in a bio-waste processing facility location case study, where we seek compromise solutions (facility locations) that balance stakeholder priorities on transportation, safety, water quality, and capital costs. This conference presentation abstract explains a new decision-making framework that computes compromise solution alternatives (reach consensus) by mitigating dissatisfactions among stakeholders as needed for SHC Decision Science and Support Tools project.

    The past decade has seen substantial policy effort directed at promoting the reclamation and reuse of urban brownfield or potentially contaminated land. This paper is based on the results of a survey regarding the role of stakeholder attitudes in managing contaminated sites at the Romanian level. Findings indicate that effective policies and programmes need to be framed within an understanding of the different needs of national development. While different perceptions were identified in regard to the meanings of several concepts and terms used in this field, important aspects related to the need for developing a correctly ranked and coordinated decision-making process were also identified. Additional findings indicate gaps in the legal mechanisms intended to promote brownfield rehabilitation in the course of redevelopment. At the same time, the survey respondents suggested several recommendations such as the necessity of developing a risk assessment to establish the level and extent of contamination that can endanger human health and the environmental integrity on a site and also the need for greater compatibility between land-use planning processes and environmental legislation related to contaminated site management. The paper presents general conclusions engaging all the recommendations drawn from the survey questionnaire as well as from the general current situation in Romania.

    Full Text Available El vigor temprano es un componente esencial del desarrollo de los cultivos en la mayoría de las condiciones ambientales. Sin embargo, no existen suficientes reportes sobre el control genético del vigor de plántula en maíz. El objetivo de este trabajo fue estimar los efectos de aptitud combinatoria para variables relacionadas con el vigor en maíz bajo estrés hídrico. Se emplearon seis líneas endocriadas de maíz: tres de ellas con alto porcentaje de germinación y las restantes con bajo porcentaje germinación bajo estrés hídrico. Semillas de las 15 cruzas posibles se evaluaron en condiciones de estrés hídrico en germinación en solución de polientilenglicol 8000 a 1,4 MPa. Se recolectaron datos sobre porcentaje de germinación, longitud de coleoptilo, número de raíces secundarias, longitud de raíz principal y radio radical. La variación debida a las cruzas simples se particionó en efectos de aptitud combinatoria general (ACG y específica (ACE de acuerdo al método 4, modelo 1, de Griffing. Las líneas 31B y P004 presentaron los valores más altos de ACG. Los caracteres relacionados al vigor fueron controlados principalmente por efectos aditivos; los efectos no aditivos fueron importantes también, sobretodo para longitud de coleóptilo.Early vigor is an essential component of crop plant development under most environmental conditions. Nevertheless, little is known about the genetic control of characters in relation to seedling vigor in maize. The objective of this work was to estimate combining ability effects for characters in relation to seedling vigor in maize under water stress. Six maize inbred lines under drought stress, three with high germination percentage, and three with low germination percentage, were crossed to obtain 15 single crosses. Crosses were evaluated under controlled laboratory conditions in polyethylene glycol 8000 solution (1.4 MPa. Data of the following characters were recorded: germination percentage

    To examine aerobic fitness, total moderate to vigorous physical activity (MVPA) and also patterns in terms of MVPA between children and adolescents with human immunodeficiency virus (HIV) and controls, and to determine whether differences, if any, are associated with HIV, sex and highly active antiretroviral therapy (HAART). A cross-sectional analysis was carried out with 130 children and adolescents, aged between 8 and 15 years, divided into two groups (HIV group= 65 patients, control group= 65 healthy participants). Total MVPA was measured by accelerometers and 5 and 10-min bouts were estimated. The peak oxygen uptake (peak VO2) was measured by breath-by-breath respiratory exchange in an incremental cycle ergometer test. HIV-positive participants had lower peak VO2 (39.2 ± 6.8 vs. 44.5 ± 9.1 ml.kg(-1)min(-1)), lower bouts of MVPA of 5-min (19.7 ± 16.6 vs. 26.6 ± 23.5) and 10-min (3.6 ± 3.9 vs. 5.8 ± 7.2), but similar total MVPA (49.5 ± 28.9 vs. 49.1 ± 30.6 min.day(-1)). HIV infection in untreated, nonprotease inhibitors (PI)- based HAART and PI-based HAART patients was associated with lower 8.5 (95%CI= 12.5-4.6), 7.1 (95%CI= 10.6-3.6) and 4.5 (95%CI= 7.0-2.0) ml.kg(-1)min(-1) of peak VO2. Children and adolescents with HIV demonstrated lower aerobic fitness compared with the controls and the absence of HAART may increase peak VO2 impairment. Lower bouts of MVPA were also observed in HIV group despite the similar values of total MVPA of controls.

    Full Text Available This study evaluated the content of reserves in the branches and assessed the vegetative vigor and yield of Niagara Branca, Niagara Rosada and Concord grapevines submitted to two harvests per vegetative cycle. The plants were subjected to a winter pruning (WP performed by means of a short pruning, and to a green pruning (GP at the end of spring performed by pruning branches from the fourth bud above the last grape cluster. The treatments included Control 1 (WP on 07-20-07/no GP, Control 2 (WP on 0-22-07/no GP, T1 (WP on 07-20-07/GP on 11-15-07, T2 (WP on 07-20-07/GP on 12-17- 07, T3 (WP on 08-22-07/GP on 11-15-07 and T4 (WP on 08-22-07/GP on 12-17-07. The variables evaluated included grapevine production for the two crops, the leaf area index (LAI throughout the vegetative cycle, and the content of reserves in the branches in the following stages: 2007 WP, first crop flowering, GP on 11-15-07, GP on 12-17-07, post-harvest of first and second crop, and 2008 WP. The WP associated to GP allowed to obtain two harvests in all cultivars being more effective in the T3. The shoots emitted by GP caused changes in the LAI and affected the dynamic of synthesis/ consumption of reserves in the branches of the grapevines. In plants with GP, there was reduction in the content of reserves at the end of the crop cycle compared to control plants. The pruning management to obtain two annual crops increased the annual production, but reduced the level of reserves of the grapevines.

    Full Text Available In the framework of VIGOR Project, a national project coordinated by the Institute of Geosciences and Earth Resources (CNR-IGG and sponsored by the Ministry of Economic Development (MiSE, dedicated to the evaluation of geothermal potential in the regions of the Convergence Objective in Italy (Puglia, Calabria, Campania and Sicily, is expected to evaluate the ability of the territory to heat exchange with the ground for air conditioning of buildings. To identify the conditions for the development of low enthalpy geothermal systems collected and organized on a regional scale geological and stratigraphic data useful for the preparation of a specific thematic mapping, able to represent in a synergistic and simplified way the physical parameters (geological, lithostratigraphic, hydrogeological, thermodynamic that most influence the subsoil behavior for thermal exchange. The litho-stratigraphic and hydrogeological database created for every region led to the production of different cartographic thematic maps, such as the thermal conductivity (lithological and stratigraphical, the surface geothermal flux, the average annual temperature of air, the climate zoning, the areas of hydrogeological restrictions. To obtain a single representation of the geo-exchange potential of the region, the different thematic maps described must be combined together by means of an algorithm, defined on the basis of the SINTACS methodology. The purpose is to weigh the contributions of the involved parameters and to produce a preliminary synthesis map able to identify the territorial use of geothermal heat pump systems, based on the geological characteristics and in agreement with the existing regulatory constraints.

    Sprint interval cycle training is a contemporary popular mode of training but its relative efficacy, under conditions of matched energy expenditure, to reduce risk factors for cardiometabolic disease is incompletely characterised, especially in young women. The purpose of this investigation was to determine the relative efficacy of six weeks of moderate-intensity cycling (MOD-C) and vigorous sprint-interval cycling (VIG-SIC) on lipid profile, insulin (INS) and insulin resistance using the homeostatic model assessment (HOMA-IR) and C-reactive protein (CRP) in inactive, overweight/obese (OW/OB) young women. Participants (BMI ≥25 kg/m(2), waist circumference ≥88 cm) were randomly assigned to MOD-C (20-30 min at 60-70% of heart rate reserve(HRR)) or VIG-SIC (5-7 repeated bouts 30-second maximal effort sprints, followed by four minutes of active recovery) supervised training three days/week for six weeks, with each group matched on energy expenditure. Adiposity (%Fat) was measured using dual x-ray absorptiometry. Forty-four participants (20.4 ± 1.6 years, 65.9% Caucasian, 29.8 ± 4.1 kg/m(2)) were included in the analysis. The improvement in CRP observed in the MOD-C group was larger than the VIG-C group (p = .034). Overall, high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C) levels improved following training (p  .05). These results indicate MOD-C training may be more effective in reducing CRP than VIG-SIC.

    Health literacy (the ability to read and understand health information) may help to support sustained participation in moderate to vigorous physical activity (MVPA) during aging; this relationship has never been examined longitudinally. This study aimed to investigate the relationship between health literacy and participation in weekly MVPA over an 8-year period among older adults. Data were from interviews with 4,345 adults aged 52-79 years in the English Longitudinal Study of Ageing from 2004/2005 to 2012/2013, analyzed in 2015. Health literacy was assessed in 2004/2005 as reading comprehension of a medicine label, defined as "low" (≤2/4 items correct); "medium" (3/4); and "high" (4/4). The outcome was maintaining weekly MVPA at all of five time points from 2004/2005 to 2012/2013. A population-weighted logistic regression model was adjusted for sociodemographic, physical health, and cognitive (memory and verbal fluency) covariates. Overall, 72% (3,128/4,345) of the sample had high health literacy; 18% (797/4,345) had medium health literacy; and 10% (420/4,345) had low health literacy. Of those with high health literacy, 59% (1,840/3,128) consistently reported weekly participation in MVPA, compared with 33% (138/420) of those with low health literacy (AOR=1.37, 95% CI=1.04, 1.80). Better memory was weakly positively associated with long-term MVPA (AOR=1.03, 95% CI=1.00, 1.05, per point increase out of 24), as was better verbal fluency (AOR=1.05, 95% CI=1.01, 1.09, per point increase out of 9). High health literacy and good cognitive function are independently associated with participation in weekly MVPA over an 8-year period during aging.

    Full Text Available Day-to-day variability and stability of children’s physical activity levels across days of the week are not well understood. Our aims were to examine the day-to-day variability of moderate-to-vigorous physical activity (MVPA, to determine factors influencing the day-to-day variability of MVPA and to estimate stability of MVPA in children. The sample comprises 686 Portuguese children (10 years of age. MVPA was assessed with an accelerometer, and BMI was computed from measured height and weight. Daily changes in MVPA and their correlates (gender, BMI, and maturity were modeled with a multilevel approach, and tracking was calculated using Foulkes & Davies γ. A total of 51.3% of boys and 26.2% of girls achieved 60 min/day of MVPA on average. Daily MVPA was lower during the weekend (23.6% of boys and 13.6% of girls comply with the recommended 60 min/day of MVPA compared to weekdays (60.8% and 35.4%, boys and girls, respectively. Normal weight children were more active than obese children and no effect was found for biological maturation. Tracking is low in both boys (γ = 0.59 ± 0.01 and girls (γ = 0.56 ± 0.01. Children’s MVPA levels during a week are highly unstable. In summary, boys are more active than girls, maturation does not affect their MVPA, and obese children are less likely to meet 60 min/day of MVPA. These results highlight the importance of providing opportunities for increasing children’s daily MVPA on all days of week, especially on the weekend.

    Full Text Available This study aimed to jointly analyse moderate-to-vigorous physical activity (MVPA and sedentariness, and their correlates, in children within their school contexts, using a multivariate multilevel approach. The sample comprises 499 Portuguese children (284 girls from 23 schools. MVPA and sedentary time were estimated by accelerometer. A set of predictor variables from both child and school levels was tested. Overall, schools explained a small amount of the total variance in both MVPA (5.6% and sedentariness (3.2%, and a correlation coefficient of −0.45 (p < 0.05 was found between MVPA and sedentariness at the child level. Number of siblings and socioeconomic status (SES were significantly associated with both sedentariness (SES: β = 2.372 ± 1.183; siblings: β = −8.127 ± 2.759 and MPVA (SES: β = −1.535 ± 0.421; siblings: β = 2.822 ± 0.977, but with opposite signs. Body Mass Index (BMI (β = −4.804 ± 1.898 and sex (male (β = 21.561 ± 3.496 were only associated with MVPA. None of the school correlates were statistically significant in their joint effects to simultaneously explain sedentariness and MVPA. These results suggest that although MVPA and sedentariness may be different constructs, they are correlated and this should be taken into account when designing strategies to reduce children’s sedentariness and increase their MVPA. In addition, the small effect of the school context on this relationship highlights the important roles of child and family characteristics.

La forma de almacenamiento en condiciones no controladas fue la seleccionada, por su prevalencia en los almacenes convencionales existentes en el país. Los resultados del trabajo condujeron a evaluar los métodos de escarificación como elementos que contribuyen a la ruptura de la dormancia. Además, permitieron tener un conocimiento más objetivo y preciso del vigor, debido a que se logró un equilibrio aceptable entre los elementos biológicos y matemáticos que se utilizaron. Al valorar en su conjunto los diferentes elementos de los estudios realizados, se propone considerar las bases conceptuales para la estimación del vigor de las semillas de especies de leguminosas tropicales arbustivas y arbóreas, u otras especies con características seminales similares en cuanto a la morfología y el comportamiento.An evaluation was made, with adequate methods, of the seed quality aspects through the study of germination, viability, dormancy and ageing. Storage under uncontrolled conditions was the form selected, due to its prevalence in the existing conventional storehouses in the country. The results of the work led to evaluate the scarification methods as elements which contribute to dormancy breakup. In addition, they allowed having more objective and accurate knowledge of vigor, because acceptable balance was achieved between the biological and mathematical elements used. When evaluating as a whole the different elements of the studies conducted, to consider the conceptual bases for estimating the vigor of seeds from tropical shrub and tree leguminous species, or other species with similar seed characteristics regarding morphology and performance is proposed.

    2013-06-01

    Full Text Available Efforts to implement collaborative adaptive management (CAM often suffer from challenges, such as an unwillingness of managers to share power, unresolved conflicts between stakeholders, and lack of capacity among stakeholders. Some aspects considered essential to CAM, e.g., trust and stakeholder capacity, may be more usefully viewed as goals for intermediate strategies rather than a set of initial conditions. From this perspective, intermediate steps that focus on social learning and building experience could overcome commonly cited barriers to CAM. An exploration of Springs Basin Working Groups, organized around major clusters of freshwater springs in north Florida, provides a case study of how these intermediate steps enable participants to become more reasonable and engaged. This strategy may be easily implemented by agencies beginning a CAM process.

In the framework of business-analysis procedures the parameters of interrelations with the key (main stakeholders are considered as strategic ones in realizing stakeholder management processes. The structure of FMOS developed on the principle of technological business-cycle and formed under the influence of additive effect of positive synergy allows implementation of the new format of business relationship with strategic stakeholders. This format differs from the traditional one in the intraspecific exchange not associated with an increase in transaction costs. The quantity reduction of the specific transaction costs and the unification of several businesses potentials for strategic purpose achievement corresponding to their business interests leads to the positive synergetic effect that according to the process-cost approach in stakeholder management results in added value increase as well.

    2017-01-01

    Full Text Available The sustainable governance of water resources relies on processes of multi-stakeholder collaborations and interactions that facilitate the sharing and integration of diverse sources and types of knowledge. In this context, it is essential to fully recognize the importance of fostering and enhancing critical connections within and between networks of relationships between different government and non-government agencies, as well as the dynamics that are in support of the development of new knowledge and practices. In Quebec, a network of watershed organizations (WOs has been put in place to serve as bridging organizations (BOs for stakeholder groups in their watershed territories. Using the WOs as a case study, this research aims to contribute to a greater understanding of how stakeholder groups can be effectively connected to support knowledge co-creation through networked relationships facilitated by BOs. In line with this overall research aim, the following research objectives are proposed: (1 to assess the quality of the knowledge that is developed and shared through the WOs and their stakeholder networks; (2 to determine the characteristics of stakeholders participating in the WOs’ networks that either hinder or support collaborations and knowledge co-creation; (3 to describe the collaborative processes and mechanisms through which the WOs facilitate stakeholder interactions and knowledge co-creation; and (4 to assess the quality of the relationships and interactions between stakeholders participating in the WOs’ collaborative networks. A comprehensive literature review is provided of collaborative network dimensions that are in support of knowledge co-creation that forms the foundation of a research framework to assess knowledge co-creation processes that are facilitated through BOs and their collaborative networks. Documented experiences have been gathered through face-to-face semi-structured interviews, as well as a Quebec-wide survey

    Full Text Available Abstract Background As many countries face primary care medical workforce shortages and find it difficult to provide timely and affordable care they seek to find new ways of delivering first point of contact health care through developing new service models. In common with other areas of rural and regional Australia, the Australian Capital Territory (ACT is currently experiencing a general practitioner (GP workforce shortage which impacts significantly on the ability of patients to access GP led primary care services. The introduction of a nurse led primary care Walk-in Centre in the ACT aimed to fulfill an unmet health care need in the community and meet projected demand for health care services as well as relieve pressure on the hospital system. Stakeholders have the potential to influence health service planning and policy, to advise on the potential of services to meet population health needs and to assess how acceptable health service innovation is to key stakeholder groups. This study aimed to ascertain the views of key stakeholders about the Walk-in Centre. Methods Stakeholders were purposively selected through the identification of individuals and organisations which had organisational or professional contact with the Walk-in Centre. Semi structured interviews around key themes were conducted with seventeen stakeholders. Results Stakeholders were generally supportive of the Walk-in Centre but identified key areas which they considered needed to be addressed. These included the service's systems, full utilisation of the nurse practitioner role and adequate education and training. It was also suggested that a doctor could be available to the Centre as a source of referral for patients who fall outside the nurses' scope of practice. The location of the Centre was seen to impact on patient flows to the Emergency Department. Conclusion Nurse led Walk-in Centres are one response to addressing primary health care medical workforce shortages

    Stakeholder viewpoints and beliefs about geologic carbon storage are not always accurate, yet they may affect the future of carbon capture and storage (CCS). Gaps in stakeholder understanding and perspectives must be addressed, and natural systems that release CO2 can be valuable tools for communicating difficult scientific concepts because they provide tangible examples of geologic principles at work. Stakeholder perceptions commonly involve a misunderstanding of geologic scale and mechanisms, and can be charged with emotions fueled by media coverage of natural disasters. One example of an event widely cited by stakeholders is the CO2 release at Lake Nyos in Cameroon in August 1986 that killed 1700 people. This event is commonly thought by stakeholders to be an analogue for a release from a CO2 storage site; however, this release occurred under a rare combination of circumstances (a 208-m-deep volcanic crater lake) not analogous to an engineered CO2 storage site. Stakeholders therefore gravitate towards natural systems to form concepts and opinions of how CO2 might behave in a geological environment, but they often choose systems that are not true analogues but that gain attention through the media because they are associated with a disaster. When chosen correctly, natural releases of CO2 may create a level of clarity for stakeholders by providing tangible concrete examples that explain difficult scientific principles and provide familiar reference points to adapt different viewpoints. We present suggestions and examples presented by scientists at an IEAGHG Workshop Natural Releases of CO2: Building Knowledge for CO2 Storage Environmental Impact Assessments', held at Maria Laach, Germany, November 2010 which brought together researchers from the EU, North America, Japan, and Australia. It also included field observations of natural CO2 releases around the Laacher See caldera lake, CO2 springs, and the Wallenborn CO2 geyser. New information from international

    Full Text Available Business Process Management (BPM has been increasingly focused as an holistic approach to manage organizations for better organizational effectiveness. BPM involves the use of innovative performance measurement systems to follow up, coordinate, control and improve processes and overall business efficacy and efficiency. In this paper we propose a global holistic perspective of integrated information, combining the view of all stakeholders and both qualitative and quantitative information, as a basic prerequisite for quality of information for better decision making. The paper includes findings from an empirical case study of measuring Parkinson's Disease Neurosurgery process, including stakeholder's view with an integrative perspective.

  13. Gall-forming insect attack patterns: a test of the Plant Vigor and the Resource Concentration Hypotheses

    Full Text Available We tested the following two hypotheses to investigate the attack patterns by gall-inducing insects on their host plant Eriotheca pubescens: (i vigorous modules are more often attacked by galling insects; and (ii E. pubescens trees associated with a higher density of co-specific individuals have a higher gall abundance. We collected terminal branches from the host plant to measure their module lengths and gall richness and abundance and determined the E. pubescens densities in a 5m radius around the focal individual. There was a higher availability of short branches. Among the four gall morphotypes, two preferred the higher branches, and the other two morphotypes had no shoot length preference. Gall attack did not present a relationship with the host plant density. Thus, the vigor of E. pubescens was a determining factor only for some gall morphotypes. In contrast, the resource concentration hypothesis was not important at an intraspecific level for gall attack in this system.

    Acute, moderate intensity aerobic exercise might improve cognition in multiple sclerosis (MS), but it is unknown if increases in core body temperature (Ctemp) that negates those effects in thermosensitive persons with MS. Fourteen fully ambulatory, thermosensitive persons with MS completed 20-min bouts of vigorous intensity treadmill walking exercise and seated quiet rest in a randomized, counterbalanced order. Ctemp was measured throughout each experimental condition. Inhibitory control (i.e., an executive function) was measured immediately prior to and following each condition. Ctemp was elevated (~0.6 °C) with vigorous exercise versus quiet rest (p exercise versus quiet rest (ηp(2) = 0.29). Exercise-related increases in Ctemp do not nullify the potential acute exercise benefits on inhibitory control in MS.

    Shigella flexneri proliferate in infected human epithelial cells at exceptionally high rates. This vigorous growth has important consequences for rapid progression to life-threatening bloody diarrhea, but the underlying metabolic mechanisms remain poorly understood. Here, we used metabolomics, proteomics, and genetic experiments to determine host and Shigella metabolism during infection in a cell culture model. The data suggest that infected host cells maintain largely normal fluxes through glycolytic pathways, but the entire output of these pathways is captured by Shigella, most likely in the form of pyruvate. This striking strategy provides Shigella with an abundant favorable energy source, while preserving host cell ATP generation, energy charge maintenance, and survival, despite ongoing vigorous exploitation. Shigella uses a simple three-step pathway to metabolize pyruvate at high rates with acetate as an excreted waste product. The crucial role of this pathway for Shigella intracellular growth suggests targets for antimicrobial chemotherapy of this devastating disease.

    Unmanned aerial vehicles (UAVs or drones) are a very promising branch of technology, and they have been utilized in agriculture—in cooperation with image processing technologies—for phenotyping and vigor diagnosis. One of the problems in the utilization of UAVs for agricultural purposes is the limitation in flight time. It is necessary to fly at a high altitude to capture the maximum number of plants in the limited time available, but this reduces the spatial resolution of the captured images...

    Objective Physical activity has been shown to attenuate the effect of the FTO polymorphism on body weight, and the heritability of body weight in twin and in family studies. The dose-response relationship between activity and the risk for inherited obesity is not well known, particularly for higher doses of vigorous exercise. Such information is needed to best prescribe an exercise dose for obesity prevention in those at risk due to their family history. Design We therefore analyzed self-repo...
