    Full Text Available As an important component in collaborative natural resource management and nonprofit governance, social capital is expected to be related to variations in the performance of land trusts. Land trusts are charitable organizations that work to conserve private land locally, regionally, or nationally. The purpose of this paper is to identify the level of structural and cognitive social capital among local land trusts, and how these two types of social capital relate to the perceived success of land trusts. The analysis integrates data for land trusts operating in the U.S. south-central Appalachian region, which includes western North Carolina, southwest Virginia, and east Tennessee. We use factor analysis to elicit different dimensions of cognitive social capital, including cooperation among board members, shared values, common norms, and communication effectiveness. Measures of structural social capital include the size and diversity of organizational networks of both land trusts and their board members. Finally, a hierarchical linear regression model is employed to estimate how cognitive and structural social capital measures, along with other organizational and individual-level attributes, relate to perceptions of land trust success, defined here as achievement of the land trusts' mission, conservation, and financial goals. Results show that the diversity of organizational partnerships, cooperation, and shared values among land trust board members are associated with higher levels of perceived success. Organizational capacity, land trust accreditation, volunteerism, and financial support are also important factors influencing perceptions of success among local, nonprofit land trusts.

    We performed statistical analyses of five conserved features of genomic islands of bacteria. Analyses were made based on 104 known genomic islands, which were identified by comparative methods. Four of these features include sequence size, abnormal G+C content, flanking tRNA gene, and embedded mobility gene, which are frequently investigated. One relatively new feature, G+C homogeneity, was also investigated. Among the 104 known genomic islands, 88.5% were found to fall in the typical length of 10-200 kb and 80.8% had G+C deviations with absolute values larger than 2%. For the 88 genomic islands whose hosts have been sequenced and annotated, 52.3% of them were found to have flanking tRNA genes and 64.7% had embedded mobility genes. For the homogeneity feature, 85% had an h homogeneity index less than 0.1, indicating that their G+C content is relatively uniform. Taking all the five features into account, 87.5% of 88 genomic islands had three of them. Only one genomic island had only one conserved feature and none of the genomic islands had zero features. These statistical results should help to understand the general structure of known genomic islands. We found that larger genomic islands tend to have relatively small G+C deviations relative to absolute values. For example, the absolute G+C deviations of 9 genomic islands longer than 100,000 bp were all less than 5%. This is a novel but reasonable result given that larger genomic islands should have greater restrictions in their G+C contents, in order to maintain the stable G+C content of the recipient genome.

    The National Trust uses conservation heating as its main method of environmental control for the care of collections in historic houses. This paper presents work the National Trust is undertaking to understand the energy use of its conservation heating systems and to operate them as energy-efficiently as possible, in the light of the National Trust's 2020 energy targets which seek to reduce overall energy consumption across the organisation by 20 % and to shift to 50 % renewable energy sources. The energy demand of conservation heating systems is analysed using degree days; measured energy consumption data are presented; and the reductions in fuel cost and CO{sub 2} emissions achievable though switching from oil-fired to wood pellet fuel, demonstrated.

  8. Status and conservation of parrots and parakeets in the Greater Antilles, Bahama Islands, and Cayman Islands

    1991-01-01

    In the 1490s a minimum of 28 species of psittacines occurred in the West Indies. Today, only 43% (12) of the species survive. All macaws and most parakeet species have been lost. Although the surviving parrot fauna of the Greater Antilles, Cayman Islands, and Bahama Islands has fared somewhat better than that of the Lesser Antilles, every species has undergone extensive reductions of populations and all but two have undergone extensive reductions in range, mostly as a result of habitat loss, but also from persecution as agricultural pests, conflicts with exotic species, harvesting for pets, and natural disasters. The Cayman Brac Parrot Amazona leucocephala hesterna with its tiny population (less than 150 individuals in the wild) and range, and the Puerto Rican Parrot A. vittata, with about 22-23 birds in the wild and 56 individuals in captivity, must be considered on the verge of extinction and in need of (in the latter's case, continuing) aggressive programmes of research and management. Other populations declining in numbers and range include the Yellow-billed Amazona collaria, and Black-billed A. agilis Parrots of Jamaica, Hispaniolan Parakeet Aratinga chloroptera, Hispaniolan Parrot Amazona ventralis, Cuban Parrot A. leucocephala leucocephala and, most seriously, Cuban Parakeet Aratinga euops. The population of the Grand Cayman Parrot (Amazona leucocephala caymanensis), although numbering only about 1,000 birds, appears stable and the current conservation programme gives hope for the survival of the race. An active conservation and public education programme has begun for the Bahama Parrot A. l. bahamensis, which still occurs in good numbers on Great Inagua Island, but is threatened on Abaco Island. Recommendations for conservation of parrots and parakeets in the region include (1) instituting long-term programmes of research to determine distribution, status, and ecology of each species; (2) developing conservation programmes through education and management

  9. Exploring conservative islands using correlated and uncorrelated noise

    In this work, noise is used to analyze the penetration of regular islands in conservative dynamical systems. For this purpose we use the standard map choosing nonlinearity parameters for which a mixed phase space is present. The random variable which simulates noise assumes three distributions, namely equally distributed, normal or Gaussian, and power law (obtained from the same standard map but for other parameters). To investigate the penetration process and explore distinct dynamical behaviors which may occur, we use recurrence time statistics (RTS), Lyapunov exponents and the occupation rate of the phase space. Our main findings are as follows: (i) the standard deviations of the distributions are the most relevant quantity to induce the penetration; (ii) the penetration of islands induce power-law decays in the RTS as a consequence of enhanced trapping; (iii) for the power-law correlated noise an algebraic decay of the RTS is observed, even though sticky motion is absent; and (iv) although strong noise intensities induce an ergodic-like behavior with exponential decays of RTS, the largest Lyapunov exponent is reminiscent of the regular islands.

    Protected area delineation and conservation action are urgently needed on marine islands, but the potential biodiversity benefits of these activities can be difficult to assess due to lack of species diversity information for lesser known taxa. We used linear mixed effects modeling and simple spatial analyses to investigate whether conservation activities based on the diversity of well-known insular taxa (birds and mammals) are likely to also capture the diversity of lesser known taxa (reptiles, amphibians, vascular land plants, ants, land snails, butterflies, and tenebrionid beetles). We assembled total, threatened, and endemic diversity data for both well-known and lesser known taxa and combined these with physical island biogeography characteristics for 1190 islands from 109 archipelagos. Among physical island biogeography factors, island area was the best indicator of diversity of both well-known and little-known taxa. Among taxonomic factors, total mammal species richness was the best indicator of total diversity of lesser known taxa, and the combination of threatened mammal and threatened bird diversity was the best indicator of lesser known endemic richness. The results of other intertaxon diversity comparisons were highly variable, however. Based on our results, we suggest that protecting islands above a certain minimum threshold area may be the most efficient use of conservation resources. For example, using our island database, if the threshold were set at 10 km(2) and the smallest 10% of islands greater than this threshold were protected, 119 islands would be protected. The islands would range in size from 10 to 29 km(2) and would include 268 lesser known species endemic to a single island, along with 11 bird and mammal species endemic to a single island. Our results suggest that for islands of equivalent size, prioritization based on total or threatened bird and mammal diversity may also capture opportunities to protect lesser known species endemic to

    Biodiversity conservation in an era of global change and scarce funding benefits from approaches that simultaneously solve multiple problems. Here, we discuss conservation management of the island scrub-jay (Aphelocoma insularis), the only island-endemic passerine species in the continental United States, which is currently restricted to 250-square-kilometer Santa Cruz Island, California. Although the species is not listed as threatened by state or federal agencies, its viability is nonetheless threatened on multiple fronts. We discuss management actions that could reduce extinction risk, including vaccination, captive propagation, biosecurity measures, and establishing a second free-living population on a neighboring island. Establishing a second population on Santa Rosa Island may have the added benefit of accelerating the restoration and enhancing the resilience of that island's currently highly degraded ecosystem. The proactive management framework for island scrub-jays presented here illustrates how strategies for species protection, ecosystem restoration, and adaptation to and mitigation of climate change can converge into an integrated solution. ?? 2011 by American Institute of Biological Sciences.

    Full Text Available The development of Reimaanlok, a national framework for the planning and establishment of community-based conservation areas in the Marshall Islands, is outlined. A team composed of international experts and local resource management professionals selected and modified an ecoregional planning approach, defined key concepts, selected conservation features and targets, compiled biogeographical information from scientific and local knowledge and carried out a national-level ecological gap assessment. Past development of community-based fisheries and conservation plans was reviewed and the lessons learned informed the development of a robust community-based planning process for the design and establishment of conservation areas on individual atolls, integrating ecosystem based management (EBM theory, traditional knowledge and management, and the particular socio-economic needs of island communities. While specific geographic, historical, cultural and economic characteristics of the Marshall Islands have created a framework that is unique, several aspects of this process offer ideas for national strategic conservation planning in other Small Island Developing States where there is a paucity of scientific data, significant and increasing threats, and where decision-making about the use of natural resources occurs primarily at the local level.

  1. A cultural landscape approach to community-based conservation in Solomon Islands

    Full Text Available International environmental organizations have an increasing commitment to the development of conservation programs in high-diversity regions where indigenous communities maintain customary rights to their lands and seas. A major challenge that these programs face is the alignment of international conservation values with those of the indigenous communities whose cooperation and support are vital. International environmental organizations are focused on biodiversity conservation, but local communities often have a different range of concerns and interests, only some of which relate to biodiversity. One solution to this problem involves adoption of a cultural landscape approach as the ethical and organizational foundation of the conservation program. In our conservation work in coastal Melanesia, we have developed a cultural landscape approach that involves the construction of a conceptual model of environment that reflects the indigenous perceptions of landscape. This model incorporates cultural, ideational, and spiritual values alongside other ecosystem services and underpins the conservation activities, priorities, and organizational structure of our programs. This cultural landscape model was a reaction to a survey of environmental values conducted by our team in which Solomon Islanders reported far greater interest in conserving cultural heritage sites than any other ecosystem resources. This caused a radical rethinking of community-based conservation programs. The methodologies we adopted are derived from the fields of archaeology and historical anthropology, in which there is an established practice of working through research problems within the framework of indigenous concepts of, and relationship to, landscape. In our work in Isabel Province, Solomon Islands, coastal communities have enthusiastically adopted conservation programs that are based on cultural landscape models that recognize indigenous values. A particularly useful tool is

  2. Conservation of erupting ungulate populations on islands – a comment

    Directory of Open Access Journals (Sweden)

    Anne Gunn

    2003-04-01

    Full Text Available A generalised model for herbivores experiencing abundant forage over time is that their numbers erupt and then decline. This model has been applied to fluctuations in caribou (Rangifer tarandus populations especially those on islands. Since this generalised model for erupting herbivores was first proposed, two assumptions have slipped in (1 that an erupting population will crash; and (2 that the crash will be density-dependent. The problem with the assumptions is that, without testing, they can lead to inappropriate management such as culls. The first assumption arises from uncritical use of earlier accounts and the second assumption from not discriminating between the effects of environmental variation from the effects of the high herbivore numbers on forage availability (density-dependence. Often typical densitydependent effects such as lowered initial reproduction, reduced early survival of calves, and subsequent calf, yearling and juvenile survival are used to justify the contention that there are too many herbivores. But such reasoning is flawed unless cause/effect relationships are established and the role of environmental variation is evaluated. We argue that it is overly simplistic to believe that every population’s subsequent performance and fate will follow a singular pattern with only one paramount factor driving and ultimately dictating an inevitable outcome. The relative importance of unpredictable abiotic factors in influencing and causing variation in the response of ungulate populations should be investigated, no matter whether those factors are sporadic or periodic.

  3. Research priorities for conservation and natural resource management in Oceania's small-island developing states.

    2018-02-01

    For conservation science to effectively inform management, research must focus on creating the scientific knowledge required to solve conservation problems. We identified research questions that, if answered, would increase the effectiveness of conservation and natural resource management practice and policy in Oceania's small-island developing states. We asked conservation professionals from academia, governmental, and nongovernmental organizations across the region to propose such questions and then identify which were of high priority in an online survey. We compared the high-priority questions with research questions identified globally and for other regions. Of 270 questions proposed by respondents, 38 were considered high priority, including: What are the highest priority areas for conservation in the face of increasing resource demand and climate change? How should marine protected areas be networked to account for connectivity and climate change? What are the most effective fisheries management policies that contribute to sustainable coral reef fisheries? High-priority questions related to the particular challenges of undertaking conservation on small-island developing states and the need for a research agenda that is responsive to the sociocultural context of Oceania. Research priorities for Oceania relative to elsewhere were broadly similar but differed in specific issues relevant to particular conservation contexts. These differences emphasize the importance of involving local practitioners in the identification of research priorities. Priorities were reasonably well aligned among sectoral groups. Only a few questions were widely considered answered, which may indicate a smaller-than-expected knowledge-action gap. We believe these questions can be used to strengthen research collaborations between scientists and practitioners working to further conservation and natural resource management in this region. © 2017 The Authors.

  5. Distributed cogeneration can have a very meaningful strategic energy conservation outcome for islands

    1997-01-01

    Since the first oil shock in 1973, many small islands have not assessed the strategic implications of dependence on oil imports, and have not opted to interfere in their own energy markets. This paper considers the notion of different levels of energy service delivery (by concentrating on local suitability), based on research relating to the Channel Island of Guernsey, and shows that significant energy savings are available. For this energy service delivery approach to be put into effect this paper suggests that a move away from the present laissez-faire supply-based stance will be necessary. Distributed cogeneration is considered in a case situation (using techniques that no small island currently employs) and shows strategic energy conservation solutions to questions no one has yet seriously asked.

    Population size is widely used as a unit of ecological analysis, yet to estimate population size requires accounting for observed and latent heterogeneity influencing dispersion of individuals across landscapes. In newly established populations, such as when animals are translocated for conservation, dispersal and availability of resources influence patterns of abundance. We developed a process to estimate population size using N-mixture models and spatial models for newly established and dispersing populations. We used our approach to estimate the population size of critically endangered St. Croix ground lizards (Ameiva polops) five years after translocation of 57 individuals to Buck Island, an offshore island of St. Croix, United States Virgin Islands. Estimates of population size incorporated abiotic variables, dispersal limits, and operative environmental temperature available to the lizards to account for low species detection. Operative environmental temperature and distance from the translocation site were always important in fitting the N-mixture model indicating effects of dispersal and species biology on estimates of population size. We found that the population is increasing its range across the island by 5-10% every six months. We spatially interpolated site-specific abundance from the N-mixture model to the entire island, and we estimated 1,473 (95% CI, 940-1,802) St. Croix ground lizards on Buck Island in 2013 corresponding to survey results. This represents a 26-fold increase since the translocation. We predicted the future dispersal of the lizards to all habitats on Buck Island, with the potential for the population to increase by another five times in the future. Incorporating biologically relevant covariates as explicit parameters in population models can improve predictions of population size and the future spread of species introduced to new localities. © 2018 by the Ecological Society of America.

  7. Snakes on the Balearic islands: an invasion tale with implications for native biodiversity conservation.

    Full Text Available Biological invasions are a major conservation threat for biodiversity worldwide. Islands are particularly vulnerable to invasive species, especially Mediterranean islands which have suffered human pressure since ancient times. In the Balearic archipelago, reptiles represent an outstanding case with more alien than native species. Moreover, in the last decade a new wave of alien snakes landed in the main islands of the archipelago, some of which were originally snake-free. The identification of the origin and colonization pathways of alien species, as well as the prediction of their expansion, is crucial to develop effective conservation strategies. In this study, we used molecular markers to assess the allochthonous status and the putative origin of the four introduced snake species (Hemorrhois hippocrepis, Malpolon monspessulanus, Macroprotodon mauritanicus and Rhinechis scalaris as well as ecological niche models to infer their patterns of invasion and expansion based on current and future habitat suitability. For most species, DNA sequence data suggested the Iberian Peninsula as the potential origin of the allochthonous populations, although the shallow phylogeographic structure of these species prevented the identification of a restricted source-area. For all of them, the ecological niche models showed a current low habitat suitability in the Balearic, which is however predicted to increase significantly in the next few decades under climate change scenarios. Evidence from direct observations and spatial distribution of the first-occurrence records of alien snakes (but also lizards and worm lizards suggest the nursery trade, and in particular olive tree importation from Iberian Peninsula, as the main pathway of introduction of alien reptiles in the Balearic islands.

    Full Text Available Coastal developments worldwide have put entire shoreline ecosystems at risk. Recently, land reclamation has been extended to the construction of whole new islands; a phenomenon that is particularly common in Asia and the Middle East and is recognised as a global conservation issue. Using Penang Island, Malaysia as a case study, we illustrate the relationship between rapid population growth and the simultaneous increase in urbanisation, land reclamation and extent of artificial shorelines; and decrease in the quality and extent of natural coastal habitats. Our goal was to provide an up-to-date assessment of the state of coastal habitats around Penang, identify knowledge gaps and identify locations that may be potentially suitable for eco-engineering. Comparisons of historical and current topographic maps revealed that land formerly consisting of coastal swamp and forest, mangrove forests, sandy beaches, and rubber and oil plantations have been lost to large-scale land reclamation and urbanisation. Between 1960 and 2015, there were increases in urbanised area, reclaimed land, and artificial shoreline extent. The total extent of mangrove forests has remained relatively stable but this balance is characterised by significant losses on the east coast coupled with increases on the west coast. Coastal development on the island is still on-going with plans for the construction of five artificial islands and another two coastal reclamation projects are either underway or scheduled for the near future. If the plans for future land reclamations are fully realized, 32.3 km2 of the 321.8 km2 island (10% will be reclaimed land and the associated negative effects on the island’s natural coastal habitats will be inevitable. This study highlights sections of the coast of Penang Island in need of effective monitoring, conservation and management and explores the possibility of incorporating ecological engineering into development projects, either

    In tropical areas, a large number of natural forests have been transformed into other plantations, which affected the water conservation function of terrestrial ecosystems. In order to clari-fy the effects of land use changes on soil water conservation function, we selected four typical land use types in the central mountainous region of Hainan Island, i.e., natural forests with stand age greater than 100 years (VF), secondary forests with stand age of 10 years (SF), areca plantations with stand age of 12 years (AF) and rubber plantations with stand age of 35 years (RF). The effects of land use change on soil water holding capacity and water conservation (presented by soil water index, SWI) were assessed. The results showed that, compared with VF, the soil water holding capacity index of other land types decreased in the top soil layer (0-10 cm). AF had the lowest soil water holding capacity in all soil layers. Soil water content and maximum water holding capacity were significantly related to canopy density, soil organic matter and soil bulk density, which indicated that canopy density, soil organic matter and compactness were important factors influencing soil water holding capacity. Compared to VF, soil water conservation of SF, AF and RF were reduced by 27.7%, 54.3% and 11.5%, respectively. The change of soil water conservation was inconsistent in different soil layers. Vegetation canopy density, soil organic matter and soil bulk density explained 83.3% of the variance of soil water conservation. It was suggested that land use conversion had significantly altered soil water holding capacity and water conservation function. RF could keep the soil water better than AF in the research area. Increasing soil organic matter and reducing soil compaction would be helpful to improve soil water holding capacity and water conservation function in land management.

    Few Malagasy children and adults are aware of the rare and unique fauna and flora indigenous to their island-continent, including flagship lemur species. Even the Malagasy ancestral proverbs never mentioned lemurs, but these same proverbs talked about the now extinct hippopotamus. Madagascar's geography, history, and economic constraints contribute to severe biodiversity loss. Deforestation on Madagascar is reported to be over 100,000 ha/year, with only 10-15% of the island retaining natural forest [Green & Sussman, 1990]. Educating children, teacher-training, and community projects about environmental and conservation efforts to protect the remaining natural habitats of endangered lemur species provide a basis for long-term changes in attitudes and practices. Case studies of three conservation education projects located in different geographical regions of Madagascar, Centre ValBio, Madagacar Wildlife Conservation Alaotra Comic Book Project, and The Ako Book Project, are presented together with their ongoing stages of development, assessment, and outcomes. We argue that while nongovernmental organizational efforts are and will be very important, the Ministry of Education urgently needs to incorporate biodiversity education in the curriculum at all levels, from primary school to university.

    Some of the biggest challenges facing wildlife today are changes to their environment from both natural and anthropogenic causes. Natural resource managers, planners, policy makers, industry and private landowners must make informed decisions and policies regarding management, conservation, and restoration of species, habitats, and ecosystem function in response to these changes. Specific needs include (1) a better understanding of population status and trends; (2) understanding of species’ habitat needs and roles in supporting ecosystem functions; (3) the ability to assess species’ responses to environmental changes and predict future responses; and (4) the development of innovative techniques and tools to better understand, minimize or prevent any unintended consequences of environmental change.

    Management of forest carbon (C) stocks is an increasingly prominent land-use issue. Knowledge of carbon storage in tropical forests is improving, but regional variations are still poorly understood, and this constrains forest management and conservation efforts associated with carbon valuation mechanisms (e.g., carbon markets). This deficiency is especially pronounced in tropical islands and low-lying coastal areas where climate change impacts are expected to be among the most severe. This study presents the first field estimate of island-wide carbon storage in ecosystems of Oceania, with special attention to the regional role of coastal mangroves, which occur on islands and coastal zones throughout the tropics. On two island groups of Micronesia (Yap and Palau), we sampled all above- and belowground C pools, including soil and vegetation, in 24 sites distributed evenly among the three major vegetation structural types: mangroves, upland forests, and open savannas (generally on degraded lands formerly forested). Total C stocks were estimated to be 3.9 and 15.2 Tg C on Yap and Palau, respectively. Mangroves contained by far the largest per-hectare C pools (830-1218 Mg C ha(-1)), with deep organic-rich soils alone storing more C (631-754 Mg C ha(-1)) than all pools combined in upland systems. Despite covering just 12-13% of land area, mangroves accounted for 24-34% of total island C stocks. Savannas (156-203 Mg C ha(-1)) contained significantly lower C stocks than upland forests (375-437 Mg C ha(-1)), suggesting that reforesting savannas where appropriate has high potential for carbon-based funding to aid restoration objectives. For mangroves, these results demonstrate the key role of these systems within the broader context of C storage in island and coastal landscapes. Sustainable management of mangrove forests and their large C stocks is of high importance at the regional scale, and climate change mitigation programs such as REDD+ could play a large role in

    Conservation and restoration goals are often defined by historical baseline conditions that occurred prior to a particular period of human disturbance, such as European settlement in North America. Nevertheless, if ecosystems were heavily influenced by native peoples prior to European settlement, conservation efforts may require active management rather than simple removal of or reductions in recent forms of disturbance. We used pre-European settlement land survey records (1859-1874) and contemporary vegetation surveys to assess changes over the past 150 years in tree species and habitat composition, forest density, and tree size structure on southern Vancouver Island and Saltspring Island, British Columbia, Canada. Several lines of evidence support the hypothesis that frequent historical burning by native peoples, and subsequent fire suppression, have played dominant roles in shaping this landscape. First, the relative frequency of fire-sensitive species (e.g., cedar [Thuja plicata]) has increased, whereas fire-tolerant species (e.g., Douglas-fir [Pseudotsuga menziesii]) have decreased. Tree density has increased 2-fold, and the proportion of the landscape in forest has greatly increased at the expense of open habitats (plains, savannas), which today contain most of the region's threatened species. Finally, the frequency distribution of tree size has shifted from unimodal to monotonically decreasing, which suggests removal of an important barrier to tree recruitment. In addition, although most of the open habitats are associated with Garry oak (Quercus garryana) at present, most of the open habitats prior to European settlement were associated with Douglas-fir, which suggests that the current focus on Garry oak as a flagship for the many rare species in savannas may be misguided. Overall, our results indicate that the maintenance and restoration of open habitats will require active management and that historical records can provide critical guidance to such

    Bioko Island, Equatorial Guinea is among the important places in Africa for the conservation of primates, but a cultural preference for bushmeat and a lack of effective law enforcement has encouraged commercial bushmeat hunting, threatening the survival of the remaining primate population. For over 13 years, we collected bushmeat market data in the Malabo market, recording over 35,000 primate carcasses, documenting "mardi gras" consumption patterns, seasonal carcass availability, and negative effects resulting from government intervention. We also conducted forest surveys throughout Bioko's two protected areas in order to localize and quantify primate populations and hunting pressure. Using these data, we were able to document the significant negative impact bushmeat hunting had on monkey populations, estimate which species are most vulnerable to hunting, and develop ecological niche models to approximate the distribution of each of Bioko's diurnal primate species. These results also have allowed for the identification of primate hotspots, such as the critically important southwest region of the Gran Caldera Scientific Reserve, and thus, priority areas for conservation on Bioko, leading to more comprehensive conservation recommendations. Current and future efforts now focus on bridging the gap between investigators and legislators in order to develop and effectively implement a management plan for Bioko's Gran Caldera Scientific Reserve and to develop a targeted educational campaign to reduce demand by changing consumer attitudes toward bushmeat. Using this multidisciplinary approach, informed by biological, socioeconomic, and cultural research, there may yet be a positive future for the primates of Bioko. © 2017 Wiley Periodicals, Inc.

    Full Text Available Preventing the loss of biodiversity is a major challenge in mega-diverse ecosystems such as coral reefs where there is a critical shortage of baseline demographic data. Threatened species assessments play a valuable role in guiding conservation action to manage and mitigate biodiversity loss, but they must be undertaken with precise information at an appropriate spatial scale to provide accurate classifications. Here we explore the regional conservation status of scleractinian corals on isolated Pacific Ocean atolls in the Republic of the Marshall Islands. We compile an integrated regional species list based upon new and historical records, and compare how well the regional threat classifications reflect species level priorities at a global scale. A similar proportion of the 240 species of hard coral recorded in the current survey are classified as Vulnerable at the regional scale as the global scale using the International Union for the Conservation of Nature (IUCN Red List criteria (23% and 20% respectively, however there are distinct differences in the composition of species. When local abundance data is taken into account, a far greater proportion of the regional diversity (up to 80% may face an elevated risk of local extinction. These results suggest coral communities on isolated Pacific coral reefs, which are often predicted to be at low risk, are still vulnerable due to the small and fragmented nature of their populations. This reinforces that to adequately protect biodiversity, ongoing threatened species monitoring and the documentation of species-level changes in abundance and distribution is imperative.

    Full Text Available AbstractPigeon islands National Park (PINP is one of the three Marine National Parks in Sri Lanka with coral reefs being the major habitat protected. A study was undertaken at PINP with the objective of understanding the challenges encountered and opportunities available for managing the park addressing both coral reef conservation and increasing tourism potential. Field visits, formal and informal group discussions, expert opinions, web based information and literature surveys were the methodology utilized.  Despise the impose of an entrance fee in May 2011,  146,375 tourists visited the 471 ha park within 40 month period indicating that one hectare of coral reefs can earn more revenue than larger terrestrial parks with charismatic species such as elephants.  Foreign tourist arrivals had increased from 11.9% in 2011 to 25.13% by 2014.  Visitor reviews indicates that their experience was either excellent (46% or very good (30% due to abundance of marine life, while12% had either a poor or a terrible visitor experience at the site owing to overcrowding, reef damage and high price. With only 21% of live coral cover in 2013, it is evident that the reef is being degraded, indicating that a Protected Area which emphasizes on collecting user-fee revenues can lose sight of its primary conservation objectives and is not undertaking sustainable tourism.  Park management effectiveness is not at desirable level (43%, mainly due to non- implementation of a scientifically based management plan. A continuous monitoring programme to check the health of the reef is need, while the introduction of a multi-tiered user fee structures can enhance the economic reruns.  Incorporating PINP into wider Seascape/landscape management through utilizing Special Area Management approach needed to be promoted. Key Words: Coral Reefs; Pigeon Island National Park; Management Effectiveness; Sustainable Tourism; Stakeholders

    Invasive alien plants threaten to biodiversity, particularly in small island with high endemicity values such as Ontoloe Island, a tourist destination area of Riung Seventeen Island in Flores. The study aims to characterized the invasive plants have attacked the conservative area in Ontoloe Island. The method used by combining the line method and the plot method with three observation stations in utilization block and four observation station in protection block. Plot of 1mx1m was used for the observation of ground cover plants and seedling, 5mx5m for the observation in stake level, 10mx10m for the observation in pole level, 20mx20m for the observation in tree level. The data level of the plants obtained then analyzed with Important Value Index (IVI). Result showed that Lamtoro plants (Leuchaena leucocephala) is the invasive alien species which has the highest IVI in both of utilization block and protection block in each level of tree, stake, and pole. There are other invasive alien plants such as Tembeleken (Lantana camara) and Bidara (Zizipus mauritiana) dominated in stake level and Alang-alang (Imperata cylindrica) dominated in seedling level. All the native plants in Ontoloe Island will be threatened their existing because of the less control of invasive alien plants. Therefore, needs serious handling by the government in order to keep the balanced of the ecosystems in Ontoloe Island to be maintained especially to not deviated from management objectives area of Komodo Dragons conservation (Varanus komodoensis Ouwens, 1912).

    Full Text Available In the Sal Island (Cape Verde there is a growing involvement, will and investment in the creation of tourism synergies. However, much of the economic potential of the island can be found submerged in the sea: it is its intrinsic 'biodiversity'. Due to this fact, and in order to balance environmental safety and human pressure, it has been developed a strategy addressing both diving and fishing purposes. That strategy includes the deployment of several artificial reefs (ARs around the island. In order to allocate demand for diving and fishing purposes, we have developed a socio-economic research approach addressing the theme of biodiversity and reefs (both natural and artificial and collected expectations from AR users by means of an inquiry method. It is hypothesized a project where some management measures are proposed aiming marine biodiversity conservation. Using the methodology named as analytic hierarchy process (AHP it was scrutinized stakeholders' perception on the best practice for marine biodiversity conservation in the Sal Island. The results showed that to submerge obsolete structures in rocky or mixed areas have a high potential, but does not gathers consensuality. As an overall conclusion, it seems that limitation of activities is the preferred management option to consider in the future.Na Ilha do Sal (Cabo Verde existe um crescente envolvimento, vontade e investimento na criação de sinergias turísticas.

  1. Orchid diversity in China’s Hainan Island: Distribution and conservation

    Directory of Open Access Journals (Sweden)

    Hu, X. Y.

    2015-12-01

    Full Text Available Orchidaceae are widely distributed in many terrestrial ecosystems except for polar and desert areas and constitute a “flagship group” in biological conservation. As the largest tropical island of China, Hainan has five tropical forest vegetation types, namely deciduous monsoon forest, lowland rainforest, montane rainforest, montane evergreen forest, and montane cloud forest. There are 317 orchid species in the island, including 33 endemic, 158 epiphytic, 148 terrestrial, and 11 saprophytic species. Most orchids, which are mainly located in central and southern parts of the island, are generally distributed in damp tropical forests in mountains at an altitude of 500–1500 m. Highest level of endemism is also centred in these areas. Orchids are especially threatened by habitat fragmentation because they grow in small populations, and fragmentation may block gene flow and result in lower genetic diversity. In addition, due to their ornamental and medicinal value, many orchids are over-collected. Therefore, orchid conservation in Hainan Island is very urgent. The aim of this article is to determine the distribution pattern of orchids and expound research and conservation status in Hainan Island, and to propose conservation strategies for the future.Las Orchidaceae se distribuyen ampliamente en muchos ecosistemas terrestres con excepción de las zonas polares y desérticas, y constituyen una suerte de «buque insignia» de la conservación biológica.

  2. Phylogeography and conservation genetics of the common wall lizard, Podarcis muralis, on islands at its northern range.

    Directory of Open Access Journals (Sweden)

    Sozos Michaelides

    Full Text Available Populations at range limits are often characterized by lower genetic diversity, increased genetic isolation and differentiation relative to populations at the core of geographical ranges. Furthermore, it is increasingly recognized that populations situated at range limits might be the result of human introductions rather than natural dispersal. It is therefore important to document the origin and genetic diversity of marginal populations to establish conservation priorities. In this study, we investigate the phylogeography and genetic structure of peripheral populations of the common European wall lizard, Podarcis muralis, on Jersey (Channel Islands, UK and in the Chausey archipelago. We sequenced a fragment of the mitochondrial cytochrome b gene in 200 individuals of P. muralis to infer the phylogeography of the island populations using Bayesian approaches. We also genotyped 484 individuals from 21 populations at 10 polymorphic microsatellite loci to evaluate the genetic structure and diversity of island and mainland (Western France populations. We detected four unique haplotypes in the island populations that formed a sub-clade within the Western France clade. There was a significant reduction in genetic diversity (HO, HE and AR of the island populations in relation to the mainland. The small fragmented island populations at the northern range margin of the common wall lizard distribution are most likely native, with genetic differentiation reflecting isolation following sea level increase approximately 7000 BP. Genetic diversity is lower on islands than in marginal populations on the mainland, potentially as a result of early founder effects or long-term isolation. The combination of restriction to specific localities and an inability to expand their range into adjacent suitable locations might make the island populations more vulnerable to extinction.

    The NRSE trust fund established with financial support from the Italian Government has succeeded in catalyzing a number of energy projects in small island developing countries. These projects have elicited a great deal of interest by local communities and opened up prospects for further utilization of locally available energy resources. The projects have created a positive impact on the quality of life of people in dispersed locations in small island developing countries by focusing on provision of renewable energy based electricity services such as solar PV lighting for homes, schools, and hospitals; radio, TV, VCR as well as medicine refrigerators. Thus it has become evident that renewable energy technologies such as solar and wind systems can have an important role to play in improving the quality of life of people in these small island countries. Market potential for these technologies is indeed substantial. However constraints and barriers still exist. One of the principal barriers is still the high initial cost of solar devices. Innovative financing including microcredit facilities needs to be explored. Efforts are also needed to strengthen local capacity to undertake assembly of components and systems, and also in the installation, maintenance, and service of renewable energy devices. Entrepreneurial activities need to be fostered through further strengthening of skills in this area. (EHS)

    Full Text Available Imperiled island foxes are inherently resource-limited by their insular ecology. We examined food use on all 6 islands where they occur to assess resource exploitation patterns. Over 40 different food items were identified with item use varying among islands. Sixteen items occurred with ≥10% frequency in annual fox diets: deer mice, birds, lizards, beetles, beetle larvae, Jerusalem crickets, silk-spinning sand crickets, grasshoppers, earwigs, snails, and fruits of toyon, manzanita, prickly pear cactus, ice plant, Australian saltbush, and summer holly. Foxes used a diversity of food items with variations among islands attributable to island-specific availabilities. Deer mice in particular appeared to be preferred. Foxes also exhibited extensive use of non-native items, such as ice plant fruits, European snails, and earwigs, and foxes may even be dependent on these items on some islands. To increase food security and promote population stability, we recommend (1 continuing and enhancing habitat restoration efforts on all islands, (2 increasing the abundance of native items in association with any removals of non-native species used by foxes, and (3 monitoring annual trends in abundance of key food items as well as periodic monitoring of item use by foxes to determine functional responses to changes in item availability.

    Full Text Available The endemic vascular flora of the Canary Islands comprises over 680, taxa collectively accounting for more than 50% of the total native flora. To investigate geographical patterns of diversity within the endemic flora, distribution data from published sources together with other field observation and herbarium data were used to compile a data matrix comprising the distributions of ca. 90% of endemic taxa scored on a 10 × 10km UTM grid. WORLDMAP was then used to investigate patterns of endemic diversity, range size rarity (a measure of endemicity, phylogenetic diversity and threatened taxon richness. Endemic taxon richness was found to be highly heterogeneous across the archipelago, with cells containing between one and 139 taxa each (0.05-22.82% of endemic diversity. Patterns of variation in range size rarity and phylogenetic diversity were found to be largely congruent with endemic diversity, although some cells exhibited markedly higher range size rarity scores than would be predicted by their endemic diversity scores. In contrast, the pattern of endangered taxon richness across the archipelago differed markedly from endemic taxon richness. Many cells in Lanzarote, Fuerteventura and Gran Canaria exhibit higher endangered taxon richness scores than would be predicted from their endemic richness scores whereas in Tenerife, El Hierro, La Palma and La Gomera, the converse is generally true. The implications of the results both for understanding the evolution of Canary Island endemic diversity and for the conservation of the region’s unique and vulnerable flora are considered.La flora vascular endémica de las Islas Canarias comprende unos 680 táxones, lo que viene a representar más del 50% de la flora nativa.

    The amplified fragment length polymorphism (AFLP) technique was used to examine genetic variation among old and newly emerged individuals of Hyophorbe lagenicaulis (the Round Island bottle palm) on Round Island to assess surviving levels of diversity in the wild population and to evaluate...... monomorphic bands. Analysis of molecular variance (AMOVA) and Shannon’s indices showed a high level of genetic variation within the wild population on Round Island and a smaller amount of genetic variation among cultivated individuals. A neighbor joining analysis resulted in an unrooted network of genetic...... distances in which the five Hyophorbe spp. were separated and much variation within H. lagenicaulis was recovered. The Round Island populations of H. lagenicaulis contain representatives of the genetic variation found within the species as a whole. However, a few individuals, both wild and cultivated...

    High-resolution ice flow modeling requires bedrock elevation and ice thickness data, consistent with one another and with modeled physics. Previous studies have shown that gridded ice thickness products that rely on standard interpolation techniques (such as Bedmap2) can be inconsistent with the conservation of mass, given observed velocity, surface elevation change, and surface mass balance, for example, near the grounding line of Pine Island Glacier, West Antarctica. Using the BISICLES ice flow model, we compare results of simulations using both Bedmap2 bedrock and thickness data, and a new interpolation method that respects mass conservation. We find that simulations using the new geometry result in higher sea level contribution than Bedmap2 and reveal decadal-scale trends in the ice stream dynamics. We test the impact of several sliding laws and find that it is at least as important to accurately represent the bedrock and initial ice thickness as the choice of sliding law.

    Aleutian/Pribilof Islands Association, Inc. (APIA) hired three part-time local community members that desire to be Energy Technicians. The energy technicians were trained in methods of weatherization assistance, energy conservation and home safety. They developed a listing of homes in the region that required weatherization, and conducted on-site weatherization and energy conservation education and a home energy and safety reviews in the communities of Akutan, False Pass, King Cove and Nelson Lagoon. Priority was given to these smaller communities as they tend to have the residences most in need of weatherization and energy conservation measures. Local residents were trained to provide all three aspects of the project: weatherization, energy conservation education and a home energy and safety review. If the total energy saved by installing these products is a 25% reduction (electrical and heating, both of which are usually produced by combustion of diesel fuel), and the average Alaska home produces 32,000 pounds of CO2 each year, so we have saved about: 66 homes x 16 tons of CO2 each year x .25 = 264 tons of CO2 each year.

    Full Text Available After a long and deliberate persecution, the grey wolf (Canis lupus is slowly recolonizing its former areas in Europe, and the genetic consequences of this process are of particular interest. Wolves, though present in mainland Estonia for a long time, have only recently started to recolonize the country's two largest islands, Saaremaa and Hiiumaa. The main objective of this study was to analyse wolf population structure and processes in Estonia, with particular attention to the recolonization of islands. Fifteen microsatellite loci were genotyped for 185 individuals across Estonia. As a methodological novelty, all putative wolf-dog hybrids were identified and removed (n = 17 from the dataset beforehand to avoid interference of dog alleles in wolf population analysis. After the preliminary filtering, our final dataset comprised of 168 "pure" wolves. We recommend using hybrid-removal step as a standard precautionary procedure not only for wolf population studies, but also for other taxa prone to hybridization. STRUCTURE indicated four genetic groups in Estonia. Spatially explicit DResD analysis identified two areas, one of them on Saaremaa island and the other in southwestern Estonia, where neighbouring individuals were genetically more similar than expected from an isolation-by-distance null model. Three blending areas and two contrasting transition zones were identified in central Estonia, where the sampled individuals exhibited strong local differentiation over relatively short distance. Wolves on the largest Estonian islands are part of human-wildlife conflict due to livestock depredation. Negative public attitude, especially on Saaremaa where sheep herding is widespread, poses a significant threat for island wolves. To maintain the long-term viability of the wolf population on Estonian islands, not only wolf hunting quota should be targeted with extreme care, but effective measures should be applied to avoid inbreeding and minimize conflicts

    Part 4: Trust Metrics; International audience; We present a mathematical formulation of a trust metric using a quality and quantity pair. Under a certain assumption, we regard trust as an additive value and define the soundness of a trust computation as not to exceed the total sum. Moreover, we point out the importance of not only soundness of each computed trust but also the stability of the trust computation procedure against changes in trust value assignment. In this setting, we define tru...

    Full Text Available Due to the high risk of the global extinction in which Patella ferruginea Gmelin, 1791 is found, it is considered of great interest to describe and quantify its demographic characteristics in those sites where it still persists, as well as to evaluate the reasons which have led this limpet to be one of the most threatened marine species in the Mediterranean Sea. Over the study period (2000-2002, systematic census were made on the perimeter of the Alboran Island (Alboran Sea, westernmost area of the Mediterranean Sea with the object to quantify the abundance of the species in the locality, as well as their external biometry and spatial distribution. As a result, the presence of a probable reproductive population of P. ferruginea was found on the island. The negative effect provoked by the continuous presence of man was proved, prejudicing the population in those zones which were more accessible for their harvesting. For this reason, it is necessary to regulate the use of the natural resources of the island to favour the conservation and spontaneous recolonisation of the zone by P. ferruginea.

  16. Impacts of Tropical Forest Disturbance Upon Avifauna on a Small Island with High Endemism: Implications for Conservation

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Tropical forests are rapidly being lost across Southeast Asia and this is predicted to have severe implications for many of the region′s bird species. However, relationships between forest disturbance and avifaunal assemblages remain poorly understood, particularly on small island ecosystems such as those found in the biodiversity ′hotspot′ of Wallacea. This study examines how avifaunal richness varies across a disturbance gradient in a forest reserve on Buton Island, southeast Sulawesi. Particular emphasis is placed upon examining responses in endemic and red-listed species with high conservation importance. Results indicate that overall avian richness increases between primary and 30-year-old regenerating secondary forest and then decreases through disturbed secondary forest, but is highest in cleared farmland. However, high species richness in farmland does not signify high species distinctiveness; bird community composition here differs significantly from that found in forest sites, and is poor in supporting forest specialists and endemic species. Certain large-bodied endemics such as the Knobbed Hornbill (Rhyticeros cassidix appear to be sensitive to moderate disturbance, with populations occurring at greatest density within primary forest. However, overall endemic species richness, as well as that of endemic frugivores and insectivores, is similar in primary and secondary forest types. Results indicate that well-established secondary forest in particular has an important role in supporting species with high conservational importance, possessing community composition similar to that found in primary forest and supporting an equally high richness of endemic species.

    Marine protected areas (MPAs) have been highlighted as a means toward effective conservation of coral reefs. New strategies are required to more effectively select MPA locations and increase the pace of their implementation. Many criteria exist to design MPA networks, but generally, it is recommended that networks conserve a diversity of species selected for, among other attributes, their representativeness, rarity, or endemicity. Because knowledge of species' spatial distribution remains scarce, efficient surrogates are urgently needed. We used five different levels of habitat maps and six spatial scales of analysis to identify under which circumstances habitat data used to design MPA networks for Wallis Island provided better representation of species than random choice alone. Protected-area site selections were derived from a rarity-complementarity algorithm. Habitat surrogacy was tested for commercial fish species, all fish species, commercially harvested invertebrates, corals, and algae species. Efficiency of habitat surrogacy varied by species group, type of habitat map, and spatial scale of analysis. Maps with the highest habitat thematic complexity provided better surrogates than simpler maps and were more robust to changes in spatial scales. Surrogates were most efficient for commercial fishes, corals, and algae but not for commercial invertebrates. Conversely, other measurements of species-habitat associations, such as richness congruence and composition similarities provided weak results. We provide, in part, a habitat-mapping methodology for designation of MPAs for Pacific Ocean islands that are characterized by habitat zonations similar to Wallis. Given the increasing availability and affordability of space-borne imagery to map habitats, our approach could appreciably facilitate and improve current approaches to coral reef conservation and enhance MPA implementation.

    Conservation practitioners frequently extrapolate data from single-species investigations when managing critically endangered populations. However, few researchers initiate work with the intent of making findings useful to conservation efforts for other species. We presented and explored the concept of conducting conservation-oriented research for suites of geographically separated populations with similar natural histories, resource needs, and extinction threats. An example was provided in the form of an investigation into the population demography of endangered Micronesian kingfishers (Todiramphus cinnamominus). We provided the first demographic parameter estimates for any of the 12 endangered Pacific Todiramphus species, and used results to develop a population projection matrix model for management throughout the insular Pacific. Further, we used the model for elasticity and simulation analyses with demographic values that randomly varied across ranges that might characterize congener populations. Results from elasticity and simulation analyses indicated that changes in breeding adult survival exerted the greatest magnitude of influence on population dynamics. However, changes in nestling survival were more consistently correlated with population dynamics as demographic rates were randomly altered. We concluded that conservation practitioners working with endangered Pacific kingfishers should primarily focus efforts on factors affecting nestling and breeder survival, and secondarily address fledgling juveniles and helpers. Further, we described how the generalized base model might be changed to focus on individual populations and discussed the potential application of multi-species models to other conservation situations. ?? 2007 Elsevier Ltd.

    Pathogenicity islands (PAIs) are mobile integrated genetic elements that contain a diverse range of virulence factors. PAIs integrate into the host chromosome at a tRNA locus that contains their specific bacterial attachment site, attB , via integrase-mediated site-specific recombination generating attL and attR sites. We identified conserved recombination modules (integrases and att sites) previously described in choleragenic Vibrio cholerae PAIs but with novel cargo genes. Clustered regularly interspaced short palindromic repeat (CRISPR)-associated proteins (Cas proteins) and a type VI secretion system (T6SS) gene cluster were identified at the Vibrio pathogenicity island 1 (VPI-1) insertion site in 19 V. cholerae strains and contained the same recombination module. Two divergent type I-F CRISPR-Cas systems were identified, which differed in Cas protein homology and content. The CRISPR repeat sequence was identical among all V. cholerae strains, but the CRISPR spacer sequences and the number of spacers varied. In silico analysis suggests that the CRISPR-Cas systems were active against phages and plasmids. A type III secretion system (T3SS) was present in 12 V. cholerae strains on a 68-kb island inserted at the same tRNA-serine insertion site as VPI-2 and contained the same recombination module. Bioinformatics analysis showed that two divergent T3SSs exist among the strains examined. Both the CRISPR and T3SS islands excised site specifically from the bacterial chromosome as complete units, and the cognate integrases were essential for this excision. These data demonstrated that identical recombination modules that catalyze integration and excision from the chromosome can acquire diverse cargo genes, signifying a novel method of acquisition for both CRISPR-Cas systems and T3SSs. IMPORTANCE This work demonstrated the presence of CRISPR-Cas systems and T3SSs on PAIs. Our work showed that similar recombination modules can associate with different cargo genes and

    Substantial phenotypic and genetic variation is often found below the species level and this may be useful in quantifying biodiversity and predicting future diversification. However, relatively few studies have tested whether different aspects of intraspecific variation show congruent patterns across populations. Here, we quantify several aspects of divergence between 13 insular populations of an island endemic bird, the Vanuatu white-eye (Zosterops flavifrons). The components of divergence studied are mitochondrial DNA (mtDNA), nuclear DNA microsatellites and morphology. These different aspects of divergence present subtly different scenarios. For instance, an mtDNA phylogenetic tree reveals a potential cryptic species on the most southerly island in Vanuatu and considerable divergence between at least two other major phylogroups. Microsatellite loci suggest that population genetic divergence between insular populations, both between and within phylogroups, is substantial, a result that is consistent with a low level of interisland gene flow. Finally, most populations were found to be strongly morphologically divergent, but no single population was morphologically diagnosable from all others. Taken together, our results show that, although many measures of divergence are concordant in this system, the number of divergent units identified varies widely depending on the characters considered and approach used. A continuum of divergence and a degree of discordance between different characters are both to be expected under simple models of evolution, but they present problems in terms of delimiting conservation units.

    Full Text Available The survey was conducted in Tapkeshwari Hill Range (THR areas, wherever threatened plant species were said to exist, based on secondary information in literature. Thirteen plant species categorized as ‘Threatened’ by the World Conservation Monitoring centre (WCMC 1994 and also listed under various threat categories in the Red Data Book of Indian Plants (Nayar & Sastry 1988 were surveyed in the THR. All the RET plants reported from the study area occupied eight major habitat types. Thorn mixed forests harbored the highest number of individuals (560 of all RET plants, followed by open scrubs (345 individuals, Acacia senegal forests (328 and thorn mixed scrubs (293. Field observations showed that except Helichrysum cutchicum, all the other RET plant species were reported with very low seedlings and regeneration ratio. This paper discusses the status, distribution and threats faced and the conservation implications at border regions of some of the threatened plants of the arid Kachchh district.

    With the scope of showing and preserving an island endangered species, the Swanka turtle, a campaign and an environmental education program were conducted. The campaign consisted in showing the species to the community, its characteristics and its threats, through mass media and visits to different local schools. The environmental education program was carried out through a Scholar Environmental Project, which consisted on the conformation of an environmental group, where cognitive, attitudinal and participative aspects were worked together. Using a constrictive methodology the children developed some knowledge about the species and Its habitats. The scope was that they modified attitudes and behaviors towards situations that contribute to environmental damage; the reinforcement of values was the central point during all the activities. The knowledge gained by the pupils and the observed changes on their attitudes and participation show the positive results that arise when the action of environmental education focuses on the people and not the resources that are to be preserved

    Loss of habitat and oiling of birds represent two major threats to marine and shoreline bird populations on Vancouver Island's west coast, since their effects are widespread and cumulative. Offshore tanker traffic and local inshore shipments of petroleum products expose the coast to high risks of oiling. Large numbers of birds are most at risk when concentrated in relatively small areas, such as highly productive feeding areas, at communal roosting sites, and around nesting colonies. Logging of mature and old-growth forests has led to destruction of the nesting habitat of marbled murrelets (Brachyramphus marmoratus), while industrial development of estuaries, mudflats, and spawning grounds of Pacific herring (Clupea harengus pallasi) has diminished feeding habitats for other marine and shoreline birds. Fisheries operations, human disturbance of colonies, and introduced predators, notably the raccoon (Procyon lotor) and mink (Mustela vison), have impacted upon local populations. Management actions and research needs to mitigate these threats are addressed. 40 refs

  10. Rethinking the Galapagos Islands as a Complex Social-Ecological System: Implications for Conservation and Management

    Full Text Available The Galapagos Islands are among the most renowned natural sites in the world. Unlike other oceanic archipelagos, the ecological and evolutionary processes characteristic of Galapagos have been minimally affected by human activities, and the archipelago still retains most of its original, unique biodiversity. However, several recent reports suggest that the development model has turned unsustainable and that the unique values of the archipelago might be seriously at risk. In response to international concern, UNESCO added Galapagos to the list of World Heritage in Danger in 2007. Our goal was to provide new insights into the origins of the present-day crisis and suggest possible management alternatives. To this end, we re-examined the Galapagos situation from a broad systems perspective, conceptualizing the archipelago as a complex social-ecological system. Past, present, and possible future trends were explored using the resilience theory as a perspective for understanding the dynamics of the system. Four major historical periods were characterized and analyzed using Holling's adaptive cycle metaphor. The current Galapagos situation was characterized as a prolonged series of crisis events followed by renewal attempts that have not yet been completed. Three plausible future scenarios were identified, with tourism acting as the primary driver of change. The current tourism model reduces the system's resilience through its effects on the economy, population growth, resource consumption, invasive species arrival, and lifestyle of the island residents. Opportunities to reorganize and maintain a desirable state do exist. However, strong political and management decisions are urgently needed to avoid an irreversible shift to a socially and environmentally undesirable regime. Key measures to achieve a new sustainability paradigm for Galapagos include modifying traditional practices to produce a more adaptive resilience-based co-management model

    Research dedicated to rare endemic plants is usually focused on one given aspect. However, holistic studies, addressing several key issues, might be more useful, supporting management programmes while unravelling basic knowledge about ecological and population-level processes. A more comprehensive approach to research is proposed, encompassing: phylogenetics/systematics, pollination biology and seed dispersal, propagation, population genetics, species distribution models (SDMs), threats and monitoring. We present a holistic study dedicated to Veronica dabneyi Hochst. ex Seub., an endangered chamaephyte endemic to the Azores. Veronica dabneyi was mainly found associated with other endemic taxa; however, invasive plants were also present and together with introduced cattle, goats and rabbits are a major threat. Most populations grow at somewhat rocky and steep locations that appeared to work as refuges. Seed set in the wild was generally high and recruitment of young plants from seed seemed to be frequent. In the laboratory, it was possible to germinate and fully develop V. dabneyi seedlings, which were planted at their site of origin. No dormancy was detected and time for 50 % germination was affected by incubation temperature. Eight new microsatellite markers were applied to 72 individuals from 7 sites. A considerable degree of admixture was found between samples from the two islands Flores and Corvo, with 98 % of the genetic variability allocated within populations. Levels of heterozygosity were high and no evidence of inbreeding was found. Species distribution models based on climatic and topographic variables allowed the estimation of the potential distribution of V. dabneyi on Flores and Corvo using ecological niche factor analysis and Maxent. The inclusion of land-use variables only slightly increased the information explained by the models. Projection of the expected habitat in Faial largely coincided with the only historic record of V. dabneyi on that island

    Will we ever learn? We'd barely recovered from Enron and WorldCom before we faced the subprime mortgage meltdown and more scandals that shook our trust in businesspeople. Which raises the question: Do we trust too much? In this article, Stanford professor and social psychologist Kramer explores the reasons we trust so easily--and, often, so unwisely. He explains that genetics and childhood learning make us predisposed to trust and that it's been a good survival mechanism. That said, our willingness to trust makes us vulnerable. Our sense of trust kicks in on remarkably simple cues, such as when people look like us or are part of our social group. We also rely on third parties to verify the character of others, sometimes to our detriment (as the victims of Bernard Madoff learned). Add in our illusions of invulnerability and our tendencies to see what we want to see and to overestimate our own judgment, and the bottom line is that we're often easily fooled. We need to develop tempered trust. For those who trust too much, that means reading cues better; for the distrustful, it means developing more receptive behaviors. Everyone should start with small acts of trust that encourage reciprocity and build up. Having a hedge against potential abuses also helps. Hollywood scriptwriters, for instance, register their treatments with the Writers Guild of America to prevent their ideas from being stolen by the executives they pitch. To attract the right relationships, people must strongly signal their own honesty, proactively allay concerns, and, if their trust is abused, retaliate. Trusting individuals in certain roles, which essentially means trusting the system that selects and trains them, also works but isn't foolproof. And don't count on due diligence alone for protection; constant vigilance is needed to make sure the landscape hasn't changed.

    Full Text Available Abstract Background Morus boninensis, is an endemic plant of the Bonin (Ogasawara Islands of Japan and is categorized as "critically endangered" in the Japanese red data book. However, little information is available about its ecological, evolutionary and genetic status, despite the urgent need for guidelines for the conservation of the species. Therefore, we adopted Moritz's MU concept, based on the species' current genetic structure, to define management units and to select mother tree candidates for seed orchards. Results Nearly all individuals of the species were genotyped on the basis of seven microsatellite markers. Genetic diversity levels in putative natural populations were higher than in putative man-made populations with the exception of those on Otouto-jima Island. This is because a limited number of maternal trees are likely to have been used for seed collection to establish the man-made populations. A model-based clustering analysis clearly distinguished individuals into nine clusters, with a large difference in genetic composition between the population on Otouto-jima Island, the putative natural populations and the putative man-made populations. The Otouto-jima population appeared to be genetically differentiated from the others; a finding that was also supported by pairwise FST and RST analysis. Although multiple clusters were detected in the putative man-made populations, the pattern of genetic diversity was monotonous in comparison to the natural populations. Conclusion The genotyping by microsatellite markers revealed strong genetic structures. Typically, artificial propagation of this species has ignored the genetic structure, relying only on seeds from Otouto-jima for replanting on other islands, because of a problem with inter-specific hybridization on Chichi-jima and Haha-jima Islands.

    Full Text Available We studied the non-marine reptile and amphibian species of the volcanic Comoro archipelago in the Western Indian Ocean, a poorly known island herpetofauna comprising numerous microendemic species of potentially high extinction risk and widespread, non-endemic and often invasive taxa. According to our data, the Comoro islands are inhabited by two amphibian species and at least 28 species of reptiles although ongoing genetic studies and unconfirmed historical records suggest an even higher species diversity. 14 of the 28 currently recognized species of terrestrial reptiles (50% and the two amphibians are endemic to a single island or to the Comoro archipelago. The majority of species are most abundant at low elevation. However, a few endemic species, like the gekkonid lizards Paroedura sanctijohannis and Phelsuma nigristriata, are more common in or even confined to higher altitudes. We created habitat maps from remotely sensed data in combination with detailed species distribution maps produced using comprehensive data from field surveys between 2000 and 2010, literature, and historical locality records based on specimens in zoological collections. Using these data, we assessed the conservation status of the endemic terrestrial reptiles and amphibians according to the IUCN Red List criteria. Our results show that although little area of natural forest remains on the Comoros, many species are abundant in degraded forest or plantations. Competition and predation by invasive species appears to be the most important threat factor for the endemic herpetofauna, together with habitat degradation and destruction, which further favours invasive species. We propose the status Endangered for three species, Vulnerable for one species, Near Threatened for six species, Least Concern for four and Data Deficient for two species. The endemic subspecies Oplurus cuvieri comorensis is proposed for the status Critically Endangered. Based on the results of this study

    Full Text Available This paper briefly discusses the prospects of using coastal wetlands as REDD+ projects for small island states. The paper contends that the city-state of Singapore would do well to enhance existing laws to more specifically address the challenges and threats faced in conserving mangroves and inter-tidal mudflats, and support their conservation and rehabilitation, not just to facilitate the implementation of REDD+ projects but also to meet other goals like biodiversity conservation and climate change adaptation. The proposal is to expand Sungei Buloh to encompass the mudflats at Kranji which is home to the mangrove horseshoe crab (Carcinoscrorpius rotundicauda; aligned with inter-tidal and coastal management strategies advanced under the auspices of the Ramsar Convention, the Convention on Biological Diversity and the IUCN. However, there are considerable challenges in maintaining an intact eco-system in the face of rapid development, not only in Singapore itself but also in the neighbouring state of Johor, Malaysia. The paper examines the specific legal strategies that will be required to meet the various objectives of conservation in the context of Singapore's laws and the challenges posed by the development plans of both Singapore and Malaysia.

    In Solomon Islands, forests have provided people with ecological services while being affected by human use and protection. This study used a quantitative ethnobotanical analysis to explore the society-forest interaction and its transformation in Roviana, Solomon Islands. We compared local plant and land uses between a rural village and urbanized village. Special attention was paid to how local people depend on biodiversity and how traditional human modifications of forest contribute to biodiversity conservation. After defining locally recognized land-use classes, vegetation surveys were conducted in seven forest classes. For detailed observations of daily plant uses, 15 and 17 households were randomly selected in the rural and urban villages, respectively. We quantitatively documented the plant species that were used as food, medicine, building materials, and tools. The vegetation survey revealed that each local forest class represented a different vegetative community with relatively low similarity between communities. Although commercial logging operations and agriculture were both prohibited in the customary nature reserve, local people were allowed to cut down trees for their personal use and to take several types of non-timber forest products. Useful trees were found at high frequencies in the barrier island's primary forest (68.4%) and the main island's reserve (68.3%). Various useful tree species were found only in the reserve forest and seldom available in the urban village. In the rural village, customary governance and control over the use of forest resources by the local people still functioned. Human modifications of the forest created unique vegetation communities, thus increasing biodiversity overall. Each type of forest had different species that varied in their levels of importance to the local subsistence lifestyle, and the villagers' behaviors, such as respect for forest reserves and the semidomestication of some species, contributed to

    Aeolian sedimentary systems in the Canary Islands differ significantly from other European and African systems due to their natural characteristics (climate, vegetation and insular isolation). Consequently, their geomorphological processes are unique. In turn, they are areas under high human pressure from touristic development.

  6. Conservation of Peary caribou based on a recalculation of the 1961 aerial survey on the Queen Elizabeth Islands, Arctic Canada

    Full Text Available The estimate of 25 845 Peary caribou (Rangifer tarandus pearyi on the Queen Elizabeth Islands (QEI in the Canadian High Arctic in summer 1961 is the only nearly range-wide 'benchmark' for the past number of caribou. No variances or confidence intervals were calculated for this estimate and no estimates were calculated for Peary caribou on the three major islands of Ellesmere, Devon, and Axel Heiberg. We reexamined the 1961 raw data by grouping the QEI into five island-complexes ('eco-units' and calculating, for each unit, the estimated number of caribou and the standard error, and the 95% confidence interval of the estimate, using a 'bootstrap' technique with 100 000 replications. Our goal was to provide an ecological basis for evaluating subsequent changes in numbers rather than relying on single-island evaluations. Our bootstrap reanalysis produced an estimate of 28 288 ± 2205 SE with a 95% CI of 20 436—37 031 Peary caribou on the QEI in summer 1961. Substantial differences in density were apparent among the five eco-units, with about a 50-fold difference from 0.01 caribou • km-2 in the Eastern eco-unit to 0.5 caribou • km-2 in the Northwestern eco-unit. The 1961 findings, with our subsequent reexamination, are crucial to any evaluation of trends for the number of Peary caribou on the QEI and the relative importance of individual eco-units for these animals. These findings also allow a more accurate evaluation of the magnitude of the subsequent decline of Peary caribou on the QEI during the last four decades and may help predict future potential levels for caribou in each of the five eco-units.

    This report was commissioned by the U.S. Fish and Wildlife Service (USFWS). The purpose was to develop a monitoring program for Kaua`i forest birds in the USFWS Strategic Habitat Conservation and adaptive management frameworks. Monitoring within those frameworks is a tool to assess resource responses to management and conservation actions, and through an iterative learning process improve our understanding of species recovery, effective management, and knowledge gaps. This report provides only the monitoring component of both frameworks, and we apply the monitoring program to the East Alaka`i Protective Fence Project.

    The Miller-Dieker syndrome (MDS), composed of characteristic facial abnormalities and a severe neuronal migration disorder affecting the cerebral cortex, is caused by visible or submicroscopic deletions of chromosome band 17p13. Twelve anonymous DNA markers were tested against a panel of somatic cell hybrids containing 17p deletions from seven MDS patients. All patients, including three with normal karyotypes, are deleted for a variable set of 5-12 markers. Two highly polymorphic VNTR (variable number of tandem repeats) probes, YNZ22 and YNH37, are codeleted in all patients tested and make molecular diagnosis for this disorder feasible. By pulsed-field gel electrophoresis, YNZ22 and YNH37 were shown to be within 30 kilobases (kb) of each other. Cosmid clones containing both VNTR sequences were identified, and restriction mapping showed them to be 100 kb were completely deleted in all patients, providing a minimum estimate of the size of the MDS critical region. A hypomethylated island and evolutionarily conserved sequences were identified within this 100-kb region, indications of the presence of one or more expressed sequences potentially involved in the pathophysiology of this disorder. The conserved sequences were mapped to mouse chromosome 11 by using mouse-rat somatic cell hybrids, extending the remarkable homology between human chromosome 17 and mouse chromosome 11 by 30 centimorgans, into the 17p telomere region

The aim of this paper is to analyze the impacts of urban-touristic development in four aeolian sedimentary systems in the Canaries: Maspalomas, Corralejo, Lambra and Jable Sur. Spatial and surface changes of variables related to geomorphology and vegetation are obtained by photo-interpretation of historical aerial photography and current orthophotos. The results indicate that the systems affected by urban-touristic development have experienced significant environmental changes. In contrast, the systems that have not been affected by building and construction of infrastructure show minor changes.

    The history of the nuclear industry in the UK has been dominated by Sellafield reprocessing site in west Cumbria. The site, formerly owned by the United Kingdom Atomic Energy Authority was transferred to the newly-formed British Nuclear Fuels plc in 1971. Although trade union representation existed at Sellafield before the emergence of BNFL, it is only after this date that collective trade union activity began to emerge. In 1977, after a long running dispute with management about the issue of radiation dose uptake, the workforce went on strike, forcing the management to question their previous 'need to know' attitude and to improve industrial relations. In 1984, it was recognised that the lobbying influence of trade unions within politics, and especially the Labour party could be used to greater effect to challenge potentially -damaging influence of anti-nuclear campaigners. The National Campaign for the Nuclear Industry (NCNI) was born, combining nine industrial and non-industrial trade unions within the nuclear industry. Its task during the last ten years has been to put forward the interests of its members collectively and to secure the, role of nuclear power. within a balanced energy policy in the political arena. In dome so, it has gained a credible voice within both the trade union movement and the Labour party. The new Thermal Oxide Reprocessing Plant (THORP) received strong support from the NCNI during its construction and commissioning phases. When it became clear that the anti-nuclear lobby had gained the upper hand and were beginning to seriously delay the necessary legal instruments required to start the plant, the power of collective action was once again recognised, and the TRUST US campaign was born. The campaign was run and organised by a clerks committee and fronted by the Trade Unions at Sellafield., and turned out to be one of the most successful] trade union campaigns in recent history. The first task involved getting, the entire workforce on

    The genetic variance-covariance matrix (G-matrix) summarizes the genetic architecture of multiple traits. It has a central role in the understanding of phenotypic divergence and the quantification of the evolutionary potential of populations. Laboratory experiments have shown that G-matrices can vary rapidly under divergent selective pressures. However, because of the demanding nature of G-matrix estimation and comparison in wild populations, the extent of its spatial variability remains largely unknown. In this study, we investigate spatial variation in G-matrices for morphological and life-history traits using long-term data sets from one continental and three island populations of blue tit (Cyanistes caeruleus) that have experienced contrasting population history and selective environment. We found no evidence for differences in G-matrices among populations. Interestingly, the phenotypic variance-covariance matrices (P) were divergent across populations, suggesting that using P as a substitute for G may be inadequate. These analyses also provide the first evidence in wild populations for additive genetic variation in the incubation period (that is, the period between last egg laid and hatching) in all four populations. Altogether, our results suggest that G-matrices may be stable across populations inhabiting contrasted environments, therefore challenging the results of previous simulation studies and laboratory experiments.

    Full Text Available Colombian coral reefs, as other reefs worldwide, have deteriorated significantly during the last few decades due to both natural and anthropogenic disturbances. The National Monitoring System for Coral Reefs in Colombia (SIMAC was established in 1998 to provide long-term data bases to assess the changes of Colombian coral reefs against perturbations and to identify the factors responsible for their decline or recovery. On the Pacific coast, data on coral and algal cover have been collected yearly during seven consecutive years (1998-2004 from 20 permanent transects in two sites at La Azufrada reef, Gorgona Island. Overall, coral cover was high (55.1%-65.7% and algal cover low (28.8%-37.5% and both exhibited significant changes among years, most notably on shallow areas. Differences between sites in both coral and algal cover were present since the study began and may be explained by differences in sedimentation stress derived from soil runoff. Differences between depths most likely stem from the effects of low tidal sub-aerial exposures. Particularly intense sub-aerial exposures occurred repeatedly during January-March, 2001 and accounted for a decrease in coral and an increase in algal cover on shallow depths observed later that year. Additionally, the shallow area on the Northern site seems to be negatively affected by the combined effect of sedimentation and low tidal exposure. However, a decrease in coral cover and an increase of algal cover since 2001 on deep areas at both sites remain unexplained. Comparisons with previous studies suggest that the reef at La Azufrada has been more resilient than other reefs in the Tropical Eastern Pacific (TEP, recovering pre-disturbance (1979 levels of coral cover within a 10 year period after the 1982-83 El Niño, which caused 85% mortality.

    The concept and phenomenon of trust and its relation to leadership has recently come into focus. What role does trust play? Can trust be created strategically? Questions like these are often raised. How we conceive of and conceptualize trust is not as often discussed. Among those conceptualizations...... flexibility of form for example, the idea that one with leadership tools can consciously bring forth trust. In the conclusion, the question about trust communication is addressed. In this section I argue that trust is positively value-laden, becausesincerity is a functional and pragmatic condition...

    This paper focuses on the leadership challenge of balancing trust and control. The relation between trust and control has for a long time been a puzzling issue for management researchers. In the paper I first show that there has been a dramatic change in the way the relation between trust...... and control has been conceptualized in trust research. While the relation between trust and control earlier was conceptualized as a more or less stable balance between trust and control, more recent research conceptualizes the relation between trust and control more as a dynamical process that involves...... an ongoing process of balancing the relation between trust and control. Second, taking the departure in the recent conceptualization of the balance between trust and control as an interactive process I discuss the challenges for management in handling this more subtle balancing of trust and control...

    'Activate' is the energy magazine for secondary schools and is part of the Education Programme which is managed on behalf of the British Nuclear Industry Forum by AEA Technology. activate is the flagship communication device between the British Nuclear Industry Forum's Education Programme and secondary schools in the UK. It was developed from a previous publication, Nuclear Bulletin. There is a need for the nuclear industry to build trust with teachers and students in the UK, where for a long time, everything that the industry has said, written or printed has been disregarded by school teachers as propaganda. Over the last few years the industry has put in a great deal of effort to position itself as a provider of educationally sound and socially acceptable information. 'Activate' was an evolution of this idea and there was a hole in the market for a lively, activity and article based magazine that could be used in the classroom. The target audience is principally teachers of science, mathematics and geography, but also includes teachers of art,, English and history with students of between 11 and 18. The results were very positive in that teachers appreciated the colourful and lively nature of activate and they felt that it provided information and opinions in an un biased and non-propagandist way. Their comments about layout, number of activities style of presentation were taken into account and during the summer of 1994 activate was remodelled ready for re launch in September. The feedback so far is good with more teachers signing up every week to receive their own free copy

  11. Influences of oceanic islands and the Pleistocene on the biogeography and evolution of two groups of Australasian parrots (Aves: Psittaciformes: Eclectus roratus, Trichoglossus haematodus complex. Rapid evolution and implications for taxonomy and conservation

    Full Text Available The Australasian region is a centre of biodiversity and endemism, mainly based on the tropical climate in combination with the large amount of islands. During the Pleistocene, islands of the Sahul Shelf (Australia, New Guinea, Aru Islands had been part of the same land mass, while islands within the Wallacea (Lesser Sunda Islands, Moluccas, Sulawesi etc. remained isolated. We investigated biogeographical avian diversification patterns of two species complexes across the Wallacea and the Sahul Shelf: the Eclectus Parrot Eclectus roratus Wagler, 1832, and the Rainbow Lorikeet Trichoglossus haematodus Linnaeus, 1771. Both species are represented by a large number of described geographical subspecies. We used mitochondrial cytochrome b (cyt b sequences for phylogenetic and network analysis to detect biogeographic roles of islands and avian diversification patterns. The number of threatened taxa in this region is increasing rapidly and there is an urgent need for (sub-species conservation in this region. Our study provides first genetic evidence for treating several island taxa as distinct species. In both species complexes similar genetic patterns were detected. Genetic diversification was higher across the islands of the Wallacea than across the islands of the Sahul Shelf. Divergence in E. roratus can be dated back about 1.38 million years ago, whereas in the younger T. haematodus it was 0.80 million years ago. Long distance dispersal was the most likely event for distribution patterns across the Wallacea and Sahul Shelf. The geographic origin of the species-complex Eclectus roratus spp. is supposed to be Wallacean, but for the species-complex Trichoglossus haematodus spp. it is supposed to be non-Wallacean. Trichoglossus euteles, so far considered a distinct species, clearly belongs to the Trichoglossus-haematodus-complex. The only case of sympatry in the complex is the distribution of T. (h. euteles and T. h. capistratus on Timor, which means a

    2014-01-01

    Williamson’s characterisation of calculativeness as inimical to trust contradicts most sociological trust research. However, a similar argument is found within trust phenomenology. This paper re-investigates Williamson’s argument from the perspective of Løgstrup’s phenomenological theory of trust....... Contrary to Williamson, however, Løgstrup’s contention is that trust, not calculativeness, is the default attitude and only when suspicion is awoken does trust falter. The paper argues that while Williamson’s distinction between calculativeness and trust is supported by phenomenology, the analysis needs...... to take actual subjective experience into consideration. It points out that, first, Løgstrup places trust alongside calculativeness as a different mode of engaging in social interaction, rather conceiving of trust as a state or the outcome of a decision-making process. Secondly, the analysis must take...

    Georg Simmel is the seminal author on trust within sociology, but though inspired by Simmel, subsequent studies of intersubjective trust have failed to address Simmel’s suggestion that trust is as differentiated as the social relations of which it is part. Rather, trust has been studied within...... limited sets of exchange or work relations. This article revisits Simmel’s concept of trust as social form in order to investigate this differentiation. From an interview study, the differentiation and limits of trust are analysed within different types of social relations. Trust is found to vary greatly...... in scope and mode influenced by the intersecting dimensions of relations, objects and situations. Furthermore, trust exists between an outer threshold of expected deceit and an inner threshold of confident reliance. The findings from the qualitative study contribute new knowledge on the diversity of trust...

    Many democratic governments recognize a duty to conserve environmental resources, including wild animals, as a public trust for current and future citizens. These public trust principles have informed two centuries of U.S.A. Supreme Court decisions and environmental laws worldwide. Nevertheless numerous populations of large-bodied, mammalian carnivores (predators) were eradicated in the 20th century. Environmental movements and strict legal protections have fostered predator recoveries across the U.S.A. and Europe since the 1970s. Now subnational jurisdictions are regaining management authority from central governments for their predator subpopulations. Will the history of local eradication repeat or will these jurisdictions adopt public trust thinking and their obligation to broad public interests over narrower ones? We review the role of public trust principles in the restoration and preservation of controversial species. In so doing we argue for the essential roles of scientists from many disciplines concerned with biological diversity and its conservation. We look beyond species endangerment to future generations' interests in sustainability, particularly non-consumptive uses. Although our conclusions apply to all wild organisms, we focus on predators because of the particular challenges they pose for government trustees, trust managers, and society. Gray wolves Canis lupus L. deserve particular attention, because detailed information and abundant policy debates across regions have exposed four important challenges for preserving predators in the face of interest group hostility. One challenge is uncertainty and varied interpretations about public trustees' responsibilities for wildlife, which have created a mosaic of policies across jurisdictions. We explore how such mosaics have merits and drawbacks for biodiversity. The other three challenges to conserving wildlife as public trust assets are illuminated by the biology of predators and the interacting

    The nature of royalty trusts as a means of financing exploration, development, production, and refining of oil sand and heavy oil to produce competitively marketable petroleum products, was reviewed. Attributes of the two distinct classes of royalty trusts - reflexive class and the fundamental class royalty trusts - and the considerations underlying each one, were summarized. The overall conclusion was that the future performance of conventional oil and gas royalty trusts (reflexive class) will depend heavily on interest rate levels and management's ability to complete acquisitions financed with new trust unit issues. Fundamental class royalty trusts also offer long term pure exposure to the underlying business, in addition to yield

    cycle has a complex of general machine building technologies which permit, if necessary, to organize in a very short period, production of non-traditional articles and avoid limitation of working places. This is well proved by the experience of 'Elemash', where in connection with the decrease of demand for nuclear fuel after the accident in Chernobyl, different products are now produced, equipment for dairy industry, tubular, heating elements, hard-alloy tooling for metal cutting and mining industries, a variety of domestic appliances. This peculiar 'conversion' permitted not only preserve the staff but provide employment of youth. We concentrate our attention on one more social side of activity of our enterprise, more of a few in the town having stable interior and exterior market for its products; this is very important in the period of newly-born market economy in Russia. Annual turnover of 'Elemash', only for export of nuclear fuel, is more tan 200 million dollars. It is natural that the majority of this sum comes as taxes to the municipal budget, where it is used for developing social infrastructure of the town (culture, port, health protection education, i.e. for the welfare of the population). Evaluating te general reaction of the population and public, which was discovered as a result of communicating in the Centre with thousands of inhabitants of the town we can state that it is quite favourable and our task is to strengthen the trust to the enterprise in the future.

  6. Factors affecting marsh vegetation at the Liberty Island Conservation Bank in the Cache Slough region of the Sacramento–San Joaquin Delta, California

    Orlando, James L.; Drexler, Judith Z.

    2017-07-07

    The Liberty Island Conservation Bank (LICB) is a tidal freshwater marsh restored for the purpose of mitigating adverse effects on sensitive fish populations elsewhere in the region. The LICB was completed in 2012 and is in the northern Cache Slough region of the Sacramento–San Joaquin Delta. The wetland vegetation at the LICB is stunted and yellow-green in color (chlorotic) compared to nearby wetlands. A study was done to investigate three potential causes of the stunted and chlorotic vegetation: (1) improper grading of the marsh plain, (2) pesticide contamination from agricultural and urban inputs upstream from the site, (3) nitrogen-deficient soil, or some combination of these. Water samples were collected from channels at five sites, and soil samples were collected from four wetlands, including the LICB, during the summer of 2015. Real-time kinematic global positioning system (RTK-GPS) elevation surveys were completed at the LICB and north Little Holland Tract, a closely situated natural marsh that has similar hydrodynamics as the LICB, but contains healthy marsh vegetation.The results showed no significant differences in carbon or nitrogen content in the surface soils or in pesticides in water among the sites. The elevation survey indicated that the mean elevation of the LICB was about 26 centimeters higher than that of the north Little Holland Tract marsh. Because marsh plain elevation largely determines the hydroperiod of a marsh, these results indicated that the LICB has a hydroperiod that differs from that of neighboring north Little Holland Tract marsh. This difference in hydroperiod contributed to the lower stature and decreased vigor of wetland vegetation at the LICB. Although the LICB cannot be regraded without great expense, it could be possible to reduce the sharp angle of the marsh edge to facilitate deeper and more frequent tidal flooding along the marsh periphery. Establishing optimal elevations for restored wetlands is necessary for obtaining

To determine the unique genetic feature of M. massiliense, we sequenced the complete genome of M. massiliense type strain JCM 15300 (corresponding to CCUG 48898. Comparative genomic analysis was performed among Mycobacterium spp. and among M. abscessus group subspp., showing that additional ß-oxidation-related genes and, notably, the mammalian cell entry (mce operon were located on a genomic island, M. massiliense Genomic Island 1 (MmGI-1, in M. massiliense. In addition, putative anaerobic respiration system-related genes and additional mycolic acid cyclopropane synthetase-related genes were found uniquely in M. massiliense. Japanese isolates of M. massiliense also frequently possess the MmGI-1 (14/44, approximately 32% and three unique conserved regions (26/44; approximately 60%, 34/44; approximately 77% and 40/44; approximately 91%, as well as isolates of other countries (Malaysia, France, United Kingdom and United States. The well-conserved genomic island MmGI-1 may play an important role in high growth potential with additional lipid metabolism, extra factors for survival in the environment or synthesis of complex membrane-associated lipids. ORFs on MmGI-1 showed similarities to ORFs of phylogenetically distant M. avium complex (MAC, suggesting that horizontal gene transfer or genetic recombination events might have occurred within MmGI-1 among M. massiliense and MAC.

    The Republic of Kiribati's Phoenix Islands Protected Area (PIPA), located in the equatorial central Pacific, is the largest and deepest UNESCO World Heritage site on earth. Created in 2008, it was the first Marine Protected Area (MPA) of its kind (at the time of inception, the largest in the world) and includes eight low-lying islands, shallow coral reefs, submerged shallow and deep seamounts and extensive open-ocean and ocean floor habitat. Due to their isolation, the shallow reef habitats have been protected de facto from severe exploitation, though the surrounding waters have been continually fished for large pelagics and whales over many decades. PIPA was created under a partnership between the Government of Kiribati and the international non-governmental organizations-Conservation International and the New England Aquarium. PIPA has a unique conservation strategy as the first marine MPA to use a conservation contract mechanism with a corresponding Conservation Trust established to be both a sustainable financing mechanism and a check-and-balance to the oversight and maintenance of the MPA. As PIPA moves forward with its management objectives, it is well positioned to be a global model for large MPA design and implementation in similar contexts. The islands and shallow reefs have already shown benefits from protection, though the pending full closure of PIPA (and assessments thereof) will be critical for determining success of the MPA as a refuge for open-ocean pelagic and deep-sea marine life. As global ocean resources are continually being extracted to support a growing global population, PIPA's closure is both timely and of global significance.

    Trust is an essential component of good healthcare. If patients trust their physicians, then the relationship between them can be a richer and more meaningful one. The patient is more likely to feel confident and able to disclose symptoms, helping diagnosis and future care. If public health and community workers are trusted, not only is it likely that their work will be easier, in that their actions will be respected and accepted, but their advice will also be sought spontaneously. Trust, can, therefore, be thought of as something that is of benefit to all: healthcare workers, individuals and communities. Trust is, generally, something to be prized and we need to do anything we can to strengthen it.

This is in turn defined as the confidence people have that strangers, i.e. fellow citizens on whom they have no specific information, will not take advantage of them (Uslaner, 2002; Bjørnskov, 2006). Using the answers to the World Values Survey question “In...... general, do you think that most people can be trusted?”, the by now quite substantial literature has found that social trust is associated with a set of different macroeconomic outcomes: economic growth, the rule of law and overall quality of governance, corruption, education, the extent of violent crime...... and subjective well-being are all influenced by the propensity of people within any nation to trust each other. The questions are therefore where trust comes from and whether or not it can be affected by public policy. The answers to these questions seem to divide researchers into two camps: the optimists...

    This article seeks to explore and analyze the relationship between autonomy and trust, and to show how these findings could be relevant to medical ethics. First, I will argue that the way in which so-called "relational autonomy theories" tie the notions of autonomy and trust together is not entirely satisfying Then, I will introduce the so-called Encapsulated Interest Account as developed by Russell Hardin. This will bring out the importance of the reasons for trust. What good reasons do we have for trusting someone? I will criticize Hardin's business model as insufficiently robust, especially in the context of health care, and then turn to another source of trust, namely, love. It may seem that trust-through-love is much better suited for the vulnerability that is often involved in health care, but I will also show that it has its own deficiencies. Good health care should therefore pay attention to both models of trust, and I will offer some tentative remarks on how to do this. © The Author 2015.

    This paper examines the role of social capital (trust) vis-à-vis the propensity of a country to be a tax haven. The empirical analysis corroborates that better governed countries have a higher ceteris paribus probability to be tax havens. However, social capital counteracts the effect of governance...... quality. This effect is so strong that the partial effect of governance quality is reversed for countries with the trust index in the top quartile – making these high trust countries less likely to be tax havens – even as governance quality is increased.

    One of the clearest results in previous studies on social trust is the robust positive relationship with educational attainment. The most common interpretation is that education has a causal effect on social trust. The theoretical argument and empirical results in this article suggest a different...... interpretation. We argue that common preadult factors such as cognitive abilities and personality traits rooted in genes and early-life family environment may confound the relationship between educational attainment and social trust. We provide new evidence on this question by utilizing the quasi......-experiment of twinning. By looking at the relationship between education and social trust within monozygotic (MZ) twin pairs, we are able to avoid potential confounders rooted in genetic factors and common environmental influences because the monozygotic twins share both.

    We describe the current state-of-the-art in Trusted Computing Technologies - focusing mainly on Intel's Trusted Execution Technology (TXT). This document is based on existing documentation and tests of two existing TXT-based systems: Intel's Trusted Boot and Invisible Things Lab's Qubes OS. We describe what features are lacking in current implementations, describe what a mature system could provide, and present a list of developments to watch. Critical systems perform operation-critical computations on high importance data. In such systems, the inputs, computation steps, and outputs may be highly sensitive. Sensitive components must be protected from both unauthorized release, and unauthorized alteration: Unauthorized users should not access the sensitive input and sensitive output data, nor be able to alter them; the computation contains intermediate data with the same requirements, and executes algorithms that the unauthorized should not be able to know or alter. Due to various system requirements, such critical systems are frequently built from commercial hardware, employ commercial software, and require network access. These hardware, software, and network system components increase the risk that sensitive input data, computation, and output data may be compromised.

  12. Computationally Modeling Interpersonal Trust

    2013-12-01

    Full Text Available We present a computational model capable of predicting—above human accuracy—the degree of trust a person has toward their novel partner by observing the trust-related nonverbal cues expressed in their social interaction. We summarize our prior work, in which we identify nonverbal cues that signal untrustworthy behavior and also demonstrate the human mind’s readiness to interpret those cues to assess the trustworthiness of a social robot. We demonstrate that domain knowledge gained from our prior work using human-subjects experiments, when incorporated into the feature engineering process, permits a computational model to outperform both human predictions and a baseline model built in naivete' of this domain knowledge. We then present the construction of hidden Markov models to incorporate temporal relationships among the trust-related nonverbal cues. By interpreting the resulting learned structure, we observe that models built to emulate different levels of trust exhibit different sequences of nonverbal cues. From this observation, we derived sequence-based temporal features that further improve the accuracy of our computational model. Our multi-step research process presented in this paper combines the strength of experimental manipulation and machine learning to not only design a computational trust model but also to further our understanding of the dynamics of interpersonal trust.

    2015-07-01

    Habitat fragmentation reduces the extent and connectivity of suitable habitats, and can lead to changes in population genetic structure. Limited gene flow among isolated demes can result in increased genetic divergence among populations, and decreased genetic diversity within demes. We assessed patterns of genetic variation in the Caribbean boa Chilabothrus monensis (Epicrates monensis) using two mitochondrial and seven nuclear markers, and relying on the largest number of specimens of these snakes examined to date. Two disjunct subspecies of C. monensis are recognized: the threatened C. m. monensis, endemic to Mona Island, and the rare and endangered C. m. granti, which occurs on various islands of the Puerto Rican Bank. Mitochondrial and nuclear markers revealed unambiguous genetic differences between the taxa, and coalescent species delimitation methods indicated that these snakes likely are different evolutionary lineages, which we recognize at the species level, C. monensis and C. granti. All examined loci in C. monensis (sensu stricto) are monomorphic, which may indicate a recent bottleneck event. Each population of C. granti exclusively contains private mtDNA haplotypes, but five of the seven nuclear genes assayed are monomorphic, and nucleotide diversity is low in the two remaining markers. The faster pace of evolution of mtDNA possibly reflects the present-day isolation of populations of C. granti, whereas the slower substitution rate of nuDNA may instead mirror the relatively recent episodes of connectivity among the populations facilitated by the lower sea level during the Pleistocene. The small degree of overall genetic variation in C. granti suggests that demes of this snake could be managed as a single unit, a practice that would significantly increase their effective population size.

For all three mantas combined (88.4%), and all individuals (manta 1-92.4%, manta 2-64.9%, manta 3-91.9%), the majority of locations occurred within 15 km of the proposed large-scale island development. Results indicated that the MPA boundaries are spatially appropriate for manta rays in the region, however, a close association to the proposed large-scale development highlights the potential threat of disruption. Conversely, the focused nature of spatial use highlights the potential for reliable ecotourism opportunities.

    2017-01-01

    A model of Trusted Measurement supporting behavior measurement based on trusted connection architecture (TCA) with three entities and three levels is proposed, and a frame to illustrate the model is given. The model synthesizes three trusted measurement dimensions including trusted identity, trusted status and trusted behavior, satisfies the essential requirements of trusted measurement, and unified the TCA with three entities and three levels.

  1. Trust transitivity in social networks.

    Oliver Richters

    Full Text Available Non-centralized recommendation-based decision making is a central feature of several social and technological processes, such as market dynamics, peer-to-peer file-sharing and the web of trust of digital certification. We investigate the properties of trust propagation on networks, based on a simple metric of trust transitivity. We investigate analytically the percolation properties of trust transitivity in random networks with arbitrary in/out-degree distributions, and compare with numerical realizations. We find that the existence of a non-zero fraction of absolute trust (i.e. entirely confident trust is a requirement for the viability of global trust propagation in large systems: The average pair-wise trust is marked by a discontinuous transition at a specific fraction of absolute trust, below which it vanishes. Furthermore, we perform an extensive analysis of the Pretty Good Privacy (PGP web of trust, in view of the concepts introduced. We compare different scenarios of trust distribution: community- and authority-centered. We find that these scenarios lead to sharply different patterns of trust propagation, due to the segregation of authority hubs and densely-connected communities. While the authority-centered scenario is more efficient, and leads to higher average trust values, it favours weakly-connected "fringe" nodes, which are directly trusted by authorities. The community-centered scheme, on the other hand, favours nodes with intermediate in/out-degrees, in detriment of the authorities and its "fringe" peers.

    The introduction of carbon charges on the use of fossil fuels in China would have a progressive impact on income distribution. This outcome, which contrasts to the regressive distributional impact found in most studies of carbon charges in industrialized countries, is driven primarily by differences between urban and rural expenditure patterns. If carbon revenues were recycled on an equal per capita basis via a 'sky trust,' the progressive impact would be further enhanced: low-income (mainly rural) households would receive more in sky-trust dividends than they pay in carbon charges, and high-income (mainly urban) households would pay more than they receive in dividends. Thus a Chinese sky trust would contribute to both lower fossil fuel consumption and greater income equality.

    Anonymity is a security property of paramount importance, as we move steadily towards a wired, online community. Its import touches upon subjects as different as eGovernance, eBusiness and eLeisure, as well as personal freedom of speech in authoritarian societies. Trust metrics are used in anonymity networks to support and enhance reliability in the absence of verifiable identities, and a variety of security attacks currently focus on degrading a user's trustworthiness in the eyes of the other users. In this paper, we analyse the privacy guarantees of the Crowds anonymity protocol, with and without onion forwarding, for standard and adaptive attacks against the trust level of honest users.

  13. The influence of political ideology on trust in science

    McCright, Aaron M.; Dentzman, Katherine; Charters, Meghan; Dietz, Thomas

    2013-12-01

    In recent years, some scholars, journalists, and science advocates have promoted broad claims that ‘conservatives distrust science’ or ‘conservatives oppose science’. We argue that such claims may oversimplify in ways that lead to empirical inaccuracies. The Anti-Reflexivity Thesis suggests a more nuanced examination of how political ideology influences views about science. The Anti-Reflexivity Thesis hypothesizes that some sectors of society mobilize to defend the industrial capitalist order from the claims of environmentalists and some environmental scientists that the current economic system causes serious ecological and public health problems. The Anti-Reflexivity Thesis expects that conservatives will report significantly less trust in, and support for, science that identifies environmental and public health impacts of economic production (i.e., impact science) than liberals. It also expects that conservatives will report a similar or greater level of trust in, and support for, science that provides new inventions or innovations for economic production (i.e., production science) than liberals. Analyzing data from a recent survey experiment with 798 adults recruited from the US general public, our results confirm the expectations of the Anti-Reflexivity Thesis. Conservatives report less trust in impact scientists but greater trust in production scientists than their liberal counterparts. We argue that further work that increases the accuracy and depth of our understanding of the relationship between political ideology and views about science is likely crucial for addressing the politicized science-based issues of our age.

This article intends to show that private approaches to land conservation could play a critical role in Taiwan’s environmental governance and argue that the legal instruments to be used in private land conservation are potentially diverse, rather than only a charitable trust can be invoked. The comprehensive understanding and comparison of the potential legal instruments in this article will help practitioners to match adequate instruments to specific real contexts and help the legislature to devise a comprehensive law reform.

    Trust is an important concept for machine intelligence and is not consistent across many applications. In this paper, we seek to understand trust from a variety of factors: humans, sensors, communications, intelligence processing algorithms and human-machine displays of information. In modeling the various aspects of trust, we provide an example from machine intelligence that supports the various attributes of measuring trust such as sensor accuracy, communication timeliness, machine processing confidence, and display throughput to convey the various attributes that support user acceptance of machine intelligence results. The example used is fusing video and text whereby an analyst needs trust information in the identified imagery track. We use the proportional conflict redistribution rule as an information fusion technique that handles conflicting data from trusted and mistrusted sources. The discussion of the many forms of trust explored in the paper seeks to provide a systems-level design perspective for information fusion trust quantification.

  18. The Condition for Generous Trust.

    Directory of Open Access Journals (Sweden)

    Obayashi Shinya

    Full Text Available Trust has been considered the "cement" of a society and is much studied in sociology and other social sciences. Most studies, however, have neglected one important aspect of trust: it involves an act of forgiving and showing tolerance toward another's failure. In this study, we refer to this concept as "generous trust" and examine the conditions under which generous trust becomes a more viable option when compared to other types of trust. We investigate two settings. First, we introduce two types of uncertainties: uncertainty as to whether trustees have the intention to cooperate, and uncertainty as to whether trustees have enough competence to accomplish the entrusted tasks. Second, we examine the manner in which trust functions in a broader social context, one that involves matching and commitment processes. Since we expect generosity or forgiveness to work differently in the matching and commitment processes, we must differentiate trust strategies into generous trust in the matching process and that in the commitment process. Our analytical strategy is two-fold. First, we analyze the "modified" trust game that incorporates the two types of uncertainties without the matching process. This simplified setting enables us to derive mathematical results using game theory, thereby giving basic insight into the trust mechanism. Second, we investigate socially embedded trust relationships in contexts involving the matching and commitment processes, using agent-based simulation. Results show that uncertainty about partner's intention and competence makes generous trust a viable option. In contrast, too much uncertainty undermines the possibility of generous trust. Furthermore, a strategy that is too generous cannot stand alone. Generosity should be accompanied with moderate punishment. As for socially embedded trust relationships, generosity functions differently in the matching process versus the commitment process. Indeed, these two types of generous

  20. Homo economicus belief inhibits trust.

    Directory of Open Access Journals (Sweden)

    Ziqiang Xin

    Full Text Available As a foundational concept in economics, the homo economicus assumption regards humans as rational and self-interested actors. In contrast, trust requires individuals to believe partners' benevolence and unselfishness. Thus, the homo economicus belief may inhibit trust. The present three experiments demonstrated that the direct exposure to homo economicus belief can weaken trust. And economic situations like profit calculation can also activate individuals' homo economicus belief and inhibit their trust. It seems that people's increasing homo economicus belief may serve as one cause of the worldwide decline of trust.

  3. Homo Economicus Belief Inhibits Trust

    Science.gov (United States)

    Xin, Ziqiang; Liu, Guofang

    2013-01-01

    As a foundational concept in economics, the homo economicus assumption regards humans as rational and self-interested actors. In contrast, trust requires individuals to believe partners’ benevolence and unselfishness. Thus, the homo economicus belief may inhibit trust. The present three experiments demonstrated that the direct exposure to homo economicus belief can weaken trust. And economic situations like profit calculation can also activate individuals’ homo economicus belief and inhibit their trust. It seems that people’s increasing homo economicus belief may serve as one cause of the worldwide decline of trust. PMID:24146907

    Probabilistic trust has been adopted as an approach to taking security sensitive decisions in modern global computing environments. Existing probabilistic trust frameworks either assume fixed behaviour for the principals or incorporate the notion of ‘decay' as an ad hoc approach to cope...... with their dynamic behaviour. Using Hidden Markov Models (HMMs) for both modelling and approximating the behaviours of principals, we introduce the HMM-based trust model as a new approach to evaluating trust in systems exhibiting dynamic behaviour. This model avoids the fixed behaviour assumption which is considered...... the major limitation of existing Beta trust model. We show the consistency of the HMM-based trust model and contrast it against the well known Beta trust model with the decay principle in terms of the estimation precision....

  6. Public trust in the healthcare system in a developing country.

    Science.gov (United States)

    Peters, Dexnell; Youssef, Farid F

    2016-04-01

    Broadly defined, trust in the healthcare system is concerned with how the public perceives the system and the actors therein as it pertains to their ability to both deliver services and seek the best interests of their clientele. Trust is important because it impacts upon a range of health behaviors including compliance and ultimately affects the ability of the healthcare system to meet its goals. While several studies exist on public trust within the developed world, few studies have explored this issue in developing countries. This paper therefore assesses public trust in the healthcare system of a developing small island nation, Trinidad and Tobago. A cross-sectional survey of adults was conducted using a questionnaire that has been successfully used across Europe. We report that trust levels in the healthcare system in Trinidad and Tobago are relatively low with less than 50% of persons indicating fair trust in the healthcare system. In addition, individual health professionals also did not score highly with lowest scores found for nurses and complementary therapists. Results on four out of five dimensions of trust also demonstrated scores significantly lower than those reported in more developed nations. Open-ended comments supported these findings with the majority of persons indicating a lack of confidence in the healthcare system. These results may reflect the reality in the wider developing world, and we suggest that bolstering trust is a needed area of focus in the delivery of healthcare services throughout the nation.

    Why are the Scandinavian countries in the European Union significantly richer than South-ern/Eastern European countries? We try to answer this question from an empirical social capital perspective. In particular, we are interested in the interplay of social trust as a positive and corruption...... capital by applying a path model that accounts for Granger-like causal effects. Our empirical results, referring to a sample of up to 25 EU countries, show that corruption might harm poor European countries but is not able to affect social trust. However, corruption in itself means that resources end up...... in the wrong places and not in socioeconomically optimal investments. There is, therefore, a direct damaging effect of corruption on wealth. This implies that economic actors have to invest higher transaction and control costs which will bind resources to non-productive purposes and thus destroy economic...

    Svendsen, Gert Tinggaard; Nilsson, Jerker

    2011-01-01

    It is often observed that members have little interest in monitoring their cooperatives. One explanation is that the members are free-riders, hoping that others will perform the task. Another explanation is that the weak member interest is a consequence of members having trust in the leadership....... These competing explanations refer to the theory of collective action and the social capital paradigm, respectively, and may be linked to the classical Gesellschaft and Gemeinschaft concepts. Hence, one may expect free-rider behavior when conditions of Gesellschaft exist and trustful behavior when Gemeinschaft...... conditions rule. These propositions get support from five studies of members’ readership of their cooperatives’ annual reports. In large and heterogeneous memberships there is free-riding behavior, which explains the members’ low interest in governing their cooperatives. To a limited extent a membership may...

  11. Trust in Digital Repositories

    Full Text Available ISO 16363:2012, Space Data and Information Transfer Systems - Audit and Certification of Trustworthy Digital Repositories (ISO TRAC, outlines actions a repository can take to be considered trustworthy, but research examining whether the repository’s designated community of users associates such actions with trustworthiness has been limited. Drawing from this ISO document and the management and information systems literatures, this paper discusses findings from interviews with 66 archaeologists and quantitative social scientists. We found similarities and differences across the disciplines and among the social scientists. Both disciplinary communities associated trust with a repository’s transparency. However, archaeologists mentioned guarantees of preservation and sustainability more frequently than the social scientists, who talked about institutional reputation. Repository processes were also linked to trust, with archaeologists more frequently citing metadata issues and social scientists discussing data selection and cleaning processes. Among the social scientists, novices mentioned the influence of colleagues on their trust in repositories almost twice as much as the experts. We discuss the implications our findings have for identifying trustworthy repositories and how they extend the models presented in the management and information systems literatures.

  12. Introduced mammals on Western Indian Ocean islands

    2016-04-01

    Full Text Available The diversity of introduced mammals and their introduction history varies greatly across the Western Indian Ocean (WIO islands, from ancient introductions in the past millennia on islands off the East coast of Africa where extant terrestrial native mammal communities exist, to very recent invasions in the past decades on islands in the Mascarene archipelago. We compile the distribution of 16 introduced mammal taxa on 28 island groups comprising almost 2000 islands. Through an exhaustive literature review and expert consultation process we recorded all mammal eradications, and species recoveries which could be attributed to introduced mammal eradication or control. All island groups have been invaded by mammals, and invasive cats and rats in particular are ubiquitous, but cultural contingency has also led to regional invasions by other mammals such as lemurs, civets and tenrecs. Mammal eradications have been attempted on 45 islands in the WIO, the majority in the Seychelles and Mauritius, and where successful have resulted in spectacular recovery of species and ecosystems. Invasive mammalian predator eradication or control in association with habitat management has led to improved conservation prospects for at least 24 species, and IUCN red-list down-listing of eight species, in the Mascarene Islands. Future island conservation prioritisation in the region will need to take account of global climate change and predicted sea-level rises and coastal inundation. Greater investment and prioritisation in island conservation in the region is warranted, given its high biodiversity values and the extent of invasions.

    Heron Island is located at the sourthern end of Australia's 2,050 km-long Great Barrier Reef. Surrounded by coral reef and home to over 1000 species of fish, scuba divers and scientists alike are drawn to the island's resort and research station. The true-color image above was taken by Space Imaging's Ikonos satellite with a resolution of 4 meters per pixel-high enough to see individual boats tied up at the small marina. The narrow channel leading from the marina to the ocean was blasted and dredged decades ago, before the island became a national park. Since then the Australian government has implemented conservation measures, such as limiting the number of tourists and removing or recycling, instead of incinerating, all trash. One of the applications of remote sensing data from Ikonos is environmental monitoring, including studies of coral reef health. For more information about the island, read Heron Island.

    2014-10-01

    There is a growing divide in how conservatives and liberals in the USA understand the issue of global warming. Prior research suggests that the American public's reliance on partisan media contributes to this gap. However, researchers have yet to identify intervening variables to explain the relationship between media use and public opinion about global warming. Several studies have shown that trust in scientists is an important heuristic many people use when reporting their opinions on science-related topics. Using within-subject panel data from a nationally representative sample of Americans, this study finds that trust in scientists mediates the effect of news media use on perceptions of global warming. Results demonstrate that conservative media use decreases trust in scientists which, in turn, decreases certainty that global warming is happening. By contrast, use of non-conservative media increases trust in scientists, which, in turn, increases certainty that global warming is happening. © The Author(s) 2013.

    Recommender systems are one of the recent inventions to deal with the ever-growing information overload in relation to the selection of goods and services in a global economy. Collaborative Filtering (CF) is one of the most popular techniques in recommender systems. The CF recommends items to a target user based on the preferences of a set of similar users known as the neighbors, generated from a database made up of the preferences of past users. In the absence of these ratings, trust between the users could be used to choose the neighbor for recommendation making. Better recommendations can b

    The Internet is an amazingly powerful tool for connecting people together, unmatched in human history. Yet, with that power comes great potential for spam and abuse. Trust metrics are an attempt to compute the set of which people are trustworthy and which are likely attackers. This chapter presents two specific trust metrics developed and deployed on the Advogato Website, which is a community blog for free software developers. This real-world experience demonstrates that the trust metrics fulfilled their goals, but that for good results, it is important to match the assumptions of the abstract trust metric computation to the real-world implementation.

This research focuses on trust in information sources by explicating the construct of trust and testing a comprehensive model on several information sources about genetically modified foods. Results from a survey of 369 participants reveal the significance of projecting competence and the role of the environment in which a target public receives information. Perceptions of regulatory, social, business, and technical environments affect how likely individuals are to follow advice from institutions like the Food and Drug Administration and the news media. Future research should incorporate knowledge levels and personal relevance as variables likely to influence trusting relationships.

    Sustainable coastal management is playing an important role in coastal resources conservation, particularly on small islands. Karimata archipelago has unique characteristics and great potential to be developed as a tourism object, one of which is Karimata Island as the largest island and also reserve area. The concept of ecotourism focuses on the ecology conservation, economic benefits, and social life. Ecotourism aims to build sustainable tourism that provides economically viable and social benefits to the community. This study aims to develop coastal management strategy based on ecotourism at Karimata Island. Spatial approaching through coastal type was done. Qualitative descriptive analysis and SWOT are used to develop sustainable management strategies for the coast of Karimata Island, where the opportunities and challenges to the development of coastal ecotourism Karimata Island also included. If this potential is optimally utilized, it can be relied as an economic opportunity for local communities. Structurally shaped coast, marine depositional coast and coast build by organism are several of coastal types found at Karimata Island. Coastal ecosystems inhabited Karimata Island are mangroves, coral reefs, and macro-algae. Karimata Island have not been optimally utilized for tourist destinations. The biggest obstacle encountered is the accessibility from Kalimantan or other island at Karimata islands. Several problems related to the utilization of coastal resources were found such as mangrove and coral reef damage, also regulation that less supportive. The results of this study are expected to provide an overview of solutions for the development of coastal tourism potentials in Karimata Island.

  10. TrustBuilder2: A Reconfigurable Framework for Trust Negotiation

    Science.gov (United States)

    Lee, Adam J.; Winslett, Marianne; Perano, Kenneth J.

    To date, research in trust negotiation has focused mainly on the theoretical aspects of the trust negotiation process, and the development of proof of concept implementations. These theoretical works and proofs of concept have been quite successful from a research perspective, and thus researchers must now begin to address the systems constraints that act as barriers to the deployment of these systems. To this end, we present TrustBuilder2, a fully-configurable and extensible framework for prototyping and evaluating trust negotiation systems. TrustBuilder2 leverages a plug-in based architecture, extensible data type hierarchy, and flexible communication protocol to provide a framework within which numerous trust negotiation protocols and system configurations can be quantitatively analyzed. In this paper, we discuss the design and implementation of TrustBuilder2, study its performance, examine the costs associated with flexible authorization systems, and leverage this knowledge to identify potential topics for future research, as well as a novel method for attacking trust negotiation systems.

  11. 'Trust my doctor, trust my pancreas': trust as an emergent quality of social practice.

    Science.gov (United States)

    Cohn, Simon

    2015-06-11

    Growing attention is being paid to the importance of trust, and its corollaries such as mistrust and distrust, in health service and the central place they have in assessments of quality of care. Although initially focussing on doctor-patient relationships, more recent literature has broadened its remit to include trust held in more abstract entities, such as organisations and institutions. There has consequently been growing interest to develop rigorous and universal measures of trust. Drawing on illustrative ethnographic material from observational research in a UK diabetes clinic, this paper supports an approach that foregrounds social practice and resists conceiving trust as solely a psychological state that can be divorced from its context. Beyond exploring the less-than-conscious nature of trust, the interpretations attend to the extent to which trust practices are distributed across a range of actors. Data from clinical encounters reveal the extent to which matters of trust can emerge from the relationships between people, and sometimes people and things, as a result of a wide range of pragmatic concerns, and hence can usefully be conceived of as an extended property of a situation rather than a person. Trust is rarely explicitly articulated, but remains a subtle feature of experience that is frequently ineffable. A practice approach highlights some of the problems with adopting a general psychological or intellectualist conception of trust. In particular, assuming it is a sufficiently stable internal state that can be stored or measured not only transforms a diffuse and often ephemeral quality into a durable thing, but ultimately presents it as a generic state that has meaning independent of the specific relationships and context that achieve it. Emphasising the context-specific nature of trust practices does not dismiss the potential of matters of trust, when they emerge, to be transposed to other contexts. But it does highlight how, on each occasion

    1995-01-01

    Nuclear utilities face unknown financial liabilities for plant decommissioning that exceed the value of present trust fund collections. The situation is a strong bet to get worse than better. Will cost escalation experienced in construction recur in decomissioning? If so, then many Nuclear Decommissioning Trusts (NDTs) are underfunded in real terms. The full consequence of an unfunded liability recognized in the later years of operation will be a ratcheting of collection rates to catch up to the revised decommission estimate. NDT planning should incorporate a conservative set of assumptions based on US experience. An NDT should be treated as a trust fund and not a pay-more-as-you-go fund.

    There is a fast-growing literature on trust in health care, especially interpersonal trust, reflecting the growing awareness in both the research and policy communities of the importance of trust. At a general level, trust as part of the broader concept of social capital is related to people's health and well-being. Trust within provider-patient relations is important for its non-specific treatment effects. Finally, trust is also important for the snooth functioning of societal institutions.(...

    Woodward, Valerie; Endacott, Ruth; Sheaff, Rod; Jones, Ray

    Foundation trusts have boards of directors that are responsible for the day-to-day running of the organisation, planning services and developing strategy. Unlike non-foundation trusts and primary care trusts (PCTs), foundation trusts are not obliged to hold directors' board meetings in public. This article describes the online availability and accessibility of the minutes of such meetings in a number of foundation trusts, non-foundation trusts and PCTs. The implications for transparency in the NHS are also discussed.

    In this thesis we aimed to unravel cancer patients’ trust in their oncologist. We investigated patients’ explanations of trust in-depth, and developed an oncology-specific questionnaire to assess trust. Using the resulting Trust in Oncologist Scale, we experimentally established the influence of oncologist communication on trust. Specifically, patients report stronger trust if the oncologist expresses medical competence, communicates in an open and honest manner, and conveys involvement and c...

    A 2-year-old girl presented to the James Paget University Hospitals Trust with croup-like symptoms and was later discharged with dexamethasone syrup. The patient re-presented 6 h later following maternal concern with signs of acute respiratory distress. After a period of clinical stability, she acutely decompensated without any prior signs of a life-threatening deterioration. She was managed using nebulised epinephrine and showed signs of clinical improvement. Although improvement persisted, the child showed signs of exhaustion following the preceding events and was later intubed with an endotracheal tube and transferred to the paediatric intensive care unit at Addenbrooke’s University Hospital, Cambridge. Endotracheal aspiration later grew parainfluenza virus, rhinovirus and Staphylococcus aureus and the patient was diagnosed with the exceptionally rare life threatening complications of croup, bacterial tracheitis. The patient was discharged from intensive care 7 days later and has since made a full recovery. PMID:22689599

    2017-12-01

    Environmental challenges, from local water quality to the effects of global climate change, are overwhelming the mainstream science community. We need help. Citizen science offers one solution pathway - in the ideal, thousands of participants engaged in authentic science that delivers high quality information not otherwise obtainable. But in the real world, are citizen science data used? And more broadly: what are the interactions between citizen science and natural resource management in service of conserving or protecting system structure and function? The Coastal Observation and Seabird Survey Team (COASST) is a rigoros citizen science program focused on documenting patterns of beached bird and marine debris abundance on beaches along the coast of the Pacific Northwest and Alaska. Housed at the University of Washington, COASST partners directly with a wide range of local, tribal, state and federal agencies to effect positive change and a wide range of scientific, community and educational outcomes. Following from years of trial, error and adaptive management, we propose a "trust pathway" between citizen science and agencies that moves from an initial contact and multiple interaction types to eventual partnership and capacity sharing. Along the way are trust catalysts, including but not limited to: stakeholder engagement, data QA/QC, interactive data analysis, housing at an academic institution, and timely, repeated communication. In this presentation, we will discuss strategies and outcomes employed by COASST for fostering trust and successful partnerships, drawing on 20 years of program experience as well as reflections from a variety of partners and stakholdres.

    2001-12-01

    Full Text Available From a scientific point of view, the Juan Fernández islands contain one of the most interesting floras of the planet. Although protected as a National Park and a World Biosphere Reserve, 400 years of human interference have left deep traces in the native plant communities. Repeated burning, overexploitation of species, and the introduction of animal and plant plagues have taken 75 % of the endemic vascular flora to the verge of extinction. In 1997, Chile's national forest service (Corporación Nacional Forestal, CONAF started an ambitious project, whose objective is the recovery of this highly complex ecosystem with a socio-ecological focus. Juan Fernández makes an interesting case, as the local people (600 persons practically live within the park, therefore impeding the exclusion of the people from any conservation program. Secondly, the relatively small size of the archipelago (100 km² permits the observation of the effects of whatever modification in the ecosystem on small scales in time and space. Thirdly, the native and introduced biota are interrelated in such a way that human-caused changes in one species population may provoke unexpected results amongst other, non-target species. The project mainly deals with the eradication or control of some animal and plant plagues, the active conservation and restoration of the flora and the inclusion of the local people in conservation planning. This article presents the park's general problems, the strategy proposed to resolve them as well as some preliminary results. This project shows the complexity of the conservation activities in practice, with diverse and complex interrelations and gaps in ecological knowledge. In this respect, the project may well serve as a model for similar programs in other placesLas islas Juan Fernández albergan una de las floras más interesantes del planeta desde el punto de vista científico.

  15. Reducing exposure to trust-related risks to avoid self-blame.

    Science.gov (United States)

    Effron, Daniel A; Miller, Dale T

    2011-02-01

    Three studies demonstrated that anticipated self-blame elicits more conservative decisions about risks that require trust than about otherwise economically identical risks that do not. Participants were more reluctant to invest money in a company when it risked failure due to fraud versus low consumer demand (Study 1), and to risk points in an economic game when its outcome ostensibly depended on another participant versus chance (Studies 2 and 3). These effects were mediated by anticipated self-blame (Studies 1 and 2). Additionally, participants who actually experienced a loss felt more self-blame when the loss violated their trust and became even more conservative in subsequent risk decisions relative to participants whose loss did not violate their trust (Study 3). No support emerged for alternative explanations based on either the perceived probability of incurring a loss or an aversion to losses that profit others. The motivational power of trust violations is discussed.

    His astute counsel, knowing smile and distinguished eloquence will be missed by many. With a pang of regret, the man himself admits that 'CERN was like a drug for me'. Last week, Jean-Daniel Mandica retired, after 40 years of loyal service. He was the trusted counsellor of every Director of the Administration and Director-General for eighteen years, from 1986 to 2003. Head of the planning unit for the Directorate and the Administration from 1986 to 1996, he was then named Head of the Directorate Services Unit in 1996, a position he held until the end of 2003. Throughout that time, he conducted key tasks for the Organization, such as restructuring the Administration and carrying out audits. His role in the creation of Microcosm and his commitment to CERN's participation in the Universal Exposition at Seville in 1992 contributed in no small part to the spread of the Laboratory's fame. Jean-Daniel Mandica's incomparable knowledge of the Administration, sense of diplomacy and great ability to listen made him a v...

    Today, it is safe to assume that any program or data can be compromised, if they are not protected by hardware within a secure area. Systems based on crypto-processors (e.g., a trusted platform module, a smart card or a hardware security module) rely on the properties of tamper resistant hardware...... to establish a tight security parameter around a reduced set of predefined functionalities. Such systems are very secure, but they impose strong constraints on the functionalities, the connectivity or the resources available within the secure area. They have not proven versatile enough to provide mainstream...... trusted storage for personal data.

  20. Establishing community trust at radioactively contaminated sites

    International Nuclear Information System (INIS)

    Simpson, E.

    1999-01-01

    Establishing community trust is an essential element in the successful remediation of a radioactively contaminated site. The US Environmental Protection Agency (EPA), Region 2 has been involved in the clean up of numerous radioactively contaminated Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), Resource Conservation Recovery Act (RCRA), and Formerly Utilized Site Remedial Action Program (FUSRAP) sites in New Jersey and New York. Each site presented a unique challenge which centered around establishing and, often, re-establishing the trust of the surrounding community. Thanks to the United States government's history regarding the use of radioactive materials, people question whether governmental regulators could possibly have the public's best interests in mind when it comes to addressing radioactively contaminated sites. It has been our experience that EPA can use its position as guardian of the environment to help establish public confidence in remedial actions. The EPA can even use its position to lend credibility to remedial activities in situations where it is not directly responsible for the clean-up. Some ways that we have found to instill community confidence are: establishing radioanalytical cross-check programs using EPA's National Air and Radiation Environmental Laboratory to provide analytical quality assurance; and establishing an environmental radiation monitoring program for the contaminated site and surrounding community.

  1. To Trust or Not to Trust? What Drives Public Trust in Science in Social Media Engagement

    Science.gov (United States)

    Hwong, Y. L.; Oliver, C.; Van Kranendonk, M. J.

    2017-12-01

    The erosion of public trust in science is a serious concern today. This climate of distrust has real consequences, from the anti-vaccination movement to climate change denials. The age of social media promises opportunities for improved interactivity between scientists and the public, which experts hope will help improve public confidence in science. However, evidence linking social media engagement and public attitude towards science is scarce. Our study aimed to help fill this gap. We examined Twitter engagement and its impact on public trust in science, focusing on two related science issues: space science and climate change. Our datasets comprised of 10,000 randomly sampled tweets over a month's period in 2016. We used human annotation and machine learning to analyse the tweets. Results revealed the level of distrust was significantly higher in the climate change tweets. However, in the climate change network, people who engaged with science personalities trust science more than those who did not. This difference in trust levels was not present in the space science network. There the two clusters of people displayed similar levels of trust in science. Additionally, we used machine learning to predict the trust labels of tweets and conducted feature analysis to find the properties of trust-inspiring tweets. Our supervised learning algorithm was able to predict trust in science in our sample tweets with 84% accuracy. The strongest predictors of trust in science (as conveyed by tweets) were similarity, presence of URL and authenticity. Contrast this with the findings of our previous study investigating the features of highly engaging space science related social media messages, authenticity is the only feature that also inspires trust. This indicates that what works to promote engagement (e.g. `retweets', `Likes') does not necessarily build trust in science. Social media science communication is not as simple as `we engage, therefore they trust'. We suggest that

  15. Trust and Online Reputation Systems

    Science.gov (United States)

    Kwan, Ming; Ramachandran, Deepak

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

  17. An Operational Semantics for Trust Policies

    In the trust-structure model of trust management, principals specify their trusting relationships with other principals in terms of trust policies. In their paper on trust structures, Carbone et al. present a language for trust policies, and provide a suitable denotational semantics. The semantics...... ensures that for any collection of trust policies, there is always a unique global trust-state, compatible with all the policies, specifying everyone's degree of trust in everyone else. However, as the authors themselves point out, the language lacks an operational model: the global trust-state is a well......-defined mathematical object, but it is not clear how principals can actually compute it. This becomes even more apparent when one considers the intended application environment: vast numbers of autonomous principals, distributed and possibly mobile. We provide a compositional operational semantics for a language...

    Global biodiversity loss is disproportionately rapid on islands, where invasive species are a major driver of extinctions. To inform conservation planning aimed at preventing extinctions, we identify the distribution and biogeographic patterns of highly threatened terrestrial vertebrates (classified by the International Union for Conservation of Nature) and invasive vertebrates on ~465,000 islands worldwide by conducting a comprehensive literature review and interviews with more than 500 experts. We found that 1189 highly threatened vertebrate species (319 amphibians, 282 reptiles, 296 birds, and 292 mammals) breed on 1288 islands. These taxa represent only 5% of Earth's terrestrial vertebrates and 41% of all highly threatened terrestrial vertebrates, which occur in vertebrates was available for 1030 islands (80% of islands with highly threatened vertebrates). Invasive vertebrates were absent from 24% of these islands, where biosecurity to prevent invasions is a critical management tool. On the 76% of islands where invasive vertebrates were present, management could benefit 39% of Earth's highly threatened vertebrates. Invasive mammals occurred in 97% of these islands, with Rattus sp. as the most common invasive vertebrate (78%; 609 islands). Our results provide an important baseline for identifying islands for invasive species eradication and other island conservation actions that reduce biodiversity loss.

  20. Class renormalization: islands around islands

    An orbit of 'class' is one that rotates about a periodic orbit of one lower class with definite frequency. This contrasts to the 'level' of a periodic orbit which is the number of elements in its continued fraction expansion. Level renormalization is conventionally used to study the structure of quasi-periodic orbits. The scaling structure of periodic orbits encircling other periodic orbits in area preserving maps is discussed here. Fixed points corresponding to the accumulation of p/q bifurcations are found and scaling exponents determined. Fixed points for q > 2 correspond to self-similar islands around islands.

  4. Social trust and ionizing radiation

    2002-07-01

    The linkages that exist between the environmental risks associated with nuclear energy production (both perceived and real) and the myriad of social and political issues and processes that influence social trust are a current issue in literature, but are not well explored, particularly for the Canadian context. This paper will examine one particular issue and its relationship with social trust: ionizing radiation and public health. Social trust is defined for this paper as including interpersonal trust, but having a much broader focus, extending to public trust in governments, institutions, corporations, and the power elite, and across whole societies. Of particular interest for the nuclear energy issue is how waning social trust may impact the functioning of democratic decision-making processes, particularly those associated with the siting of waste facilities. Social trust is a central issue in the management of environmental risks, particularly those related to high technology; its absence is seen as a major cause of intractable conflict in decisions related to nuclear power generation and waste disposal. Understanding the dynamics of social trust is important if a resolution is to be found to the nuclear waste management debate in Canada, that is, one that involves broad public, or social, support. For instance, what factors cause distrust to emerge, and when distrust emerges, what authorities do members of affected communities seek out for information and support? This paper begins to examine social trust in relation to human health and ionizing radiation, particularly low dose radiation from radioactive wastes resulting from uranium and radium processing activities in Port Hope, Ontario. These activities date back to the 1930s and are of great concern to community members. This paper looks at some of the roots of public concern, for example, scientific uncertainty around whether or not human health is compromised by exposure to low dose ionizing radiation

    We study how trust is generated in society. In a two-sector model, we analyze two communities. In the bonding community people do not trust people outside their regular networks. In the bridging community people choose to trust strangers when they meet them. The hypothesis is that when trust is only bonding, it cannot accumulate. Our theoretical contribution is to show that when trust is only bonding then the economy’s level of trust moves to an unstable equilibrium that may under certain con...

    Communities are bound together by trust among their members. Trust thrives when a pervasive sense of fairness exists. Evidence suggests that trust has social, professional, and economic value for today's organizations, making it worthy of attention. Matters of trust and justice are important and timely for nurse leaders to consider given the challenge to improve practice settings in a manner that enhances nurse satisfaction. The aim of this article is to make explicit the value in building organizational justice and trust within an organization's nursing community. Nursing leadership strategies are integrated, thus offering practical guidance in creating a culture of justice, making trust explicit, and establishing trustworthiness.

  10. Modelling trading networks and the role of trust

    Barrio, Rafael A.; Govezensky, Tzipe; Ruiz-Gutiérrez, Élfego; Kaski, Kimmo K.

    2017-04-01

    We present a simple dynamical model for describing trading interactions between agents in a social network by considering only two dynamical variables, namely money and goods or services, that are assumed conserved over the whole time span of the agents' trading transactions. A key feature of the model is that agent-to-agent transactions are governed by the price in units of money per goods, which is dynamically changing, and by a trust variable, which is related to the trading history of each agent. All agents are able to sell or buy, and the decision to do either has to do with the level of trust the buyer has in the seller, the price of the goods and the amount of money and goods at the disposal of the buyer. Here we show the results of extensive numerical calculations under various initial conditions in a random network of agents and compare the results with the available related data. In most cases the agreement between the model results and real data turns out to be fairly good, which allow us to draw some general conclusions as how different trading strategies could affect the distribution of wealth in different kinds of societies. Our calculations reveal the striking effects of trust in commercial relations, namely that trust makes trading links more robust and the wealth distribution more even as well as allows for the existence of a healthy middle class.

  11. Do professional boundaries limit trust?

    Smythe, Elizabeth; Hennessy, Julia; Abbott, Max; Hughes, Frances

    2018-02-01

    The present study uses stories of mental health support workers talking about their relationship with clients to wonder about how trust might be limited by the professional boundaries of nursing. The writing arose out of an appreciative inquiry study looking at the role of mental health support workers. Participants talked about how they worked with their clients. As researchers, we were struck by the depth of trust that was built between worker and client. We have brought a phenomenological lens to wonder about the nature of trust, as shown in the data. The original research sought to identify what was working well for mental health support workers. The present study brings a phenomenological interpretive approach to four stories from the discovery phase of the study, with our thinking informed by Heidegger and van Manen. Interviews were conducted with 26 mental health support workers and six stakeholders in 2012-2103. For this paper, we drew from those transcripts stories of three mental health support workers and one stakeholder. Through a process of talking together, writing, and rewriting, we wondered about the meaning within these stories, with a strong focus on how trust was enacted. We saw that mental health support workers in this study, by not carrying the boundaries of being 'professional', seemed free to grow a stronger relationship of trust which was therapeutic. We ask: Is it time to rethink how professional boundaries limit the level of trust achieved with clients to the detriment of impactful care? © 2017 Australian College of Mental Health Nurses Inc.

  17. Trust and Distrust in E-Commerce

    Directory of Open Access Journals (Sweden)

    Suk-Joo Lee

    2018-03-01

    Full Text Available Trust is the key ingredient for sustainable transactions. In the concept of trust, the trustor trusts the trustees. In e-commerce, the trustor is the buyer and the trustees are the intermediaries and the seller. Intermediaries provide the web-based infrastructure that enables buyers and sellers to make transactions. Trust is the buyer’s judgment and comprises two distinct concepts; both trust and distrust reside in the trustor. The purpose of this study was to examine the complicated effects of trust and distrust on a buyer’s purchase intentions. Previous studies have provided theoretical frameworks illustrating co-existent trust and distrust, trust transfers from one to another, and trust in buyer-intermediary-seller relationships. Based on these frameworks, this study (i presented a holistic model that contained the judgment of buyers resulting in trust or distrust in the intermediary and the seller; (ii investigated trust and distrust transfer from the intermediary to the seller, and (iii explored the effects of various antecedents that affect trust and distrust. To validate the proposed model, we employed Partial Least Squares (PLS. A summary of key findings are as follows. First, buyer’s trust in an intermediary positively affected his or her trust in the seller, positively influencing purchase intention. In other words, we found the trust transfer from an intermediary to its seller. Second, distrust in an intermediary directly impacted on the buyer’s perceived risk, negatively influencing his or her purchase intentions. Third, structural assurance and perceived website quality of an intermediary gave a positive impact on buyer’s trust in the intermediary. The results of this study shed light on the necessity of managing both trust and distrust to facilitate sales in e-commerce.

  19. Adequate trust avails, mistaken trust matters: on the moral responsibility of doctors as proxies for patients' trust in biobank research.

    Science.gov (United States)

    Johnsson, Linus; Helgesson, Gert; Hansson, Mats G; Eriksson, Stefan

    2013-11-01

    In Sweden, most patients are recruited into biobank research by non-researcher doctors. Patients' trust in doctors may therefore be important to their willingness to participate. We suggest a model of trust that makes sense of such transitions of trust between domains and distinguishes adequate trust from mistaken trust. The unique position of doctors implies, we argue, a Kantian imperfect duty to compensate for patients' mistaken trust. There are at least three kinds of mistaken trust, each of which requires a different set of countermeasures. First, trust is mistaken when necessary competence is lacking; the competence must be developed or the illusion dispelled. Second, trust is irrational whenever the patient is mistaken about his actual reasons for trusting. Care must therefore be taken to support the patient's reasoning and moral agency. Third, some patients inappropriately trust doctors to recommend only research that will benefit them directly. Such trust should be counteracted by nurturing a culture where patients expect to be asked occasionally to contribute to the common good. © 2012 John Wiley & Sons Ltd.

    Full Text Available Innovations and constant change are inevitable parts of our everyday lives. It is not only because advanced technologies are more effective, but mostly because in the 21st century more and more realise that scarce resources – among them the safe and clean environment as such - necessitate a paradigm change and intense innovation. This revolution is easily trackable in the organisational and (supranational policies. However, innovation, and its necessary prerequisites are seldom investigated from the individuals’ point of view. It is easy to understand that inter-organisational trust is inevitable on both the consumers’ and the providers’ (innovators’ side, however, it has to be made clear that an innovative organisation has to create a trusting environment within the company, in order to foster collaboration, the generation of new ideas, creativity and finally innovation. The present paper endeavours to call attention to the notion of trust and its antecedents and consequences in relation to innovations. The aim is to provide assistance in understanding how to develop trust in each other and hence foster further innovations and development.

The Ombud is there to help you to find your way out before the point of no return is reached.   Reliability, integrity, expertise and good will: these are the four pillars on which trust is built. Trust between colleagues may break down for many different reasons, including misunderstandings, and the way to restoring the relationship is through working on these four pillars. For instance, if we assume that we do indeed have the expertise to deal with a particular task assigned to us, we may need to improve our reliability by making sure that we meet deadlines and expectations or demonstrate our integrity by acknowledging and accepting accountability for this, all the while showing that we are doing our best to do whatever it takes to achieve the common goals and restore our colleagues’ faith in us.

Despite the increasing attention that trust has received recently in the environmental management literature, the influence that individual cognitive and behavioral factors may play in influencing levels of trust in resource management institutions, and their associated scientific assessments, remains unclear. This paper uses the case of fisheries management in the northeast to explore the relationships between an individual's knowledge of the resource, perceptions of resource health, and participatory experience on levels of trust. Using survey data collected from 244 avid recreational anglers in the Northeast U.S., we test these relationships using structural equation modeling. Results indicate that participation in fisheries management is associated with increased trust across all aspects of fisheries management. In addition, higher ratings of resource health by anglers are associated with higher levels of trust of state and regional institutions, but not federal institutions or scientific methods.

    OpenAIRE

    Johansen, Svein Tvedt

    2007-01-01

    In this dissertation I develop a theoretical model on the effects of risk on the formation of trust in the initial stages of a relationship. Risk is proposed to influence trust in two ways: First, risk exerts a direct influence on trust. Risk may decrease trust, increase trust, or increase trust under specific conditions. Second, risk may affect the level of trust indirectly by influencing the effect of social stimuli on the formation of trust. In this second indirect effect of risk, ri...

  9. The Effects of Trust Transference, Mobile Attributes and Enjoyment on Mobile Trust

    2015-01-01

    Full Text Available Trust is essential in building relationships. In mobile commerce, as in electronic commerce, trust is even more valuable given the absence of human contact and direct observation of the service provider. Despite the importance of trust for mobile commerce, there has been little academic effort to study the relationships between mobile devices unique components of interactivity and customer trust, or the relationship between offline, online and mobile trust. This study proposes a trust-mediated model for customer attitude and transaction intentions in mobile commerce contexts that incorporates trust transference and unique factors present in mobile commerce. Data were collected in an online survey and analyzed via structural equations modeling. Results suggest that trust transferred from online contexts and ease of use have significant effects on mobile trust formation, while also indicating that mobile trust influences consumers’ attitudes and intentions to purchase using mobile devices.

    The cross-country correlation between social trust and income equality is well documented, but few studies examine the direction of causality. We show theoretically that by facilitating cooperation, trust may lead to more equal outcomes, while the feedback from inequality to trust is ambiguous....... Using a structural equation model estimated on a large country sample, we find that trust has a positive effect on both market and net income equality. Larger welfare states lead to higher net equality but neither net income equality nor welfare state size seems to have a causal effect on trust. We...

  14. Economic and Other Determinants of Political Trust

    2016-01-01

    Full Text Available Political trust is important for the effective functioning of government. This paper uses cross country regression analysis to see whether three different measures of economic performance matter for political trust. The results lend support to the hypothesis that political trust is influenced by economic growth, the standard of living, and the appropriate use of government spending. In addition, the paper considers two institutional variables, perceived independence of the judiciary and the degree of democracy to assess their effect on political trust. It finds that perceived judicial independence has a positive effect on political trust, but democracy has a negative effect.

  15. Terrestrial bird population trends on Aguiguan (Goat Island), Mariana Islands

    The island of Aguiguan is part of the Mariana archipelago and currently supports populations of four endemic species, including one endemic genus, Cleptornis. Bird population trends since 1982 were recently assessed on the neighbouring islands of Saipan, Tinian, and Rota indicating declines in some native species. Point-transect surveys were conducted in 2008 by the U.S. Fish and Wildlife Service to assess population densities and trends on Aguiguan. Densities for six of the nine native birds—White-throated Ground-dove Gallicolumba xanthonura, Collared Kingfisher Todiramphus chloris, Rufous Fantail Rhipidura rufifrons, Golden White-eye Cleptornis marchei, Bridled White-eye Zosterops conspicillatus and Micronesian Starling Aplonis opaca—and the non-native bird—Island Collared-dove Streptopelia bitorquata—were significantly greater in 2008 than in 1982. No differences in densities were detected among the surveys for Mariana Fruit-dove Ptilinopus roseicapilla, and Micronesian MyzomelaMyzomela rubratra. Three federally and locally listed endangered birds—Nightingale Reed-warbler Acrocephalus luscinius, Mariana Swiftlet Collocalia bartschi, and Micronesian Megapode Megapodius laperous)—were either not detected during the point-transect counts, the surveys were not appropriate for the species, or the numbers of birds detected were too small to estimate densities. The factors behind the increasing trends for some species are unknown but may be related to increased forest cover on the island since 1982. With declining trends for some native species on neighbouring islands, the increasing and stable trends on Aguiguan is good news for forest bird populations in the region, as Aguiguan populations can help support conservation efforts on other islands in the archipelago.

    Full Text Available In the widest sense, this paper focuses on the problematization (and operationalization of the concept of trust and its social context, with a special emphasis on its multiple meanings, the ways of establishing trust, as well as its functions. After pointing to the various definitions of trust that highlight its cognitive, behavioral, and relational groundings, we proceed to examine the aspects of 'social embeddedness' of trust. In this context, we highlight the structural aspect of trust relations, their institutional embeddedness, mediation through cultural meanings, as well as the wider context of social circumstances and limitations. We place a special emphasis on the concept of 'trust culture', its morphogenesis and functions, as well as the significance of trust culture in the context of diminishing the social uncertainty that arises in the situations when trust is demonstrated. Finally, we point to the social functions of trust on the macro level, the functional substitutes for trust, as well as the relationship between trust and social capital.

    Theories of modernity and risk society argue that increasing levels of risk fundamentally alter or lower the level of trust in society. In this article we argue that this assumption is based in a fallacious theoretical link between trust and risk. Rather than calculative assessment of risk...... and specific events, trust directs anticipation towards process. First, we outline dominant approaches to trust as a question of actions and uncertainty of outcomes, arguing that these approaches treat trust and chance as interchangeable, conflating the different socio-temporalities within which risk and trust......, respectively, reside.

    Wortham, Robert H.; Theodorou, Andreas

    2017-07-01

    As robot reasoning becomes more complex, debugging becomes increasingly hard based solely on observable behaviour, even for robot designers and technical specialists. Similarly, non-specialist users have difficulty creating useful mental models of robot reasoning from observations of robot behaviour. The EPSRC Principles of Robotics mandate that our artefacts should be transparent, but what does this mean in practice, and how does transparency affect both trust and utility? We investigate this relationship in the literature and find it to be complex, particularly in nonindustrial environments where, depending on the application and purpose of the robot, transparency may have a wider range of effects on trust and utility. We outline our programme of research to support our assertion that it is nevertheless possible to create transparent agents that are emotionally engaging despite having a transparent machine nature.

    Endocrinologists can make significant contributions to conservation biology by helping to understand the mechanisms by which organisms cope with changing environments. Field endocrine techniques have advanced rapidly in recent years and can provide substantial information on the growth, stress, and reproductive status of individual animals, thereby providing insight into current and future responses of populations to changes in the environment. Environmental stressors and reproductive status can be detected nonlethally by measuring a number of endocrine-related endpoints, including steroids in plasma, living and nonliving tissue, urine, and feces. Information on the environmental or endocrine requirements of individual species for normal growth, development, and reproduction will provide critical information for species and ecosystem conservation. For many taxa, basic information on endocrinology is lacking, and advances in conservation endocrinology will require approaches that are both “basic” and “applied” and include integration of laboratory and field approaches.

  7. Vulnerability assessment of small islands to tourism: The case of the Marine Tourism Park of the Gili Matra Islands, Indonesia

    2016-04-01

    Full Text Available The Indonesian government is currently directing its focus of development on the optimum uses of marine and coastal ecosystem services including the marine and coastal tourism. One of the main locus of coastal and marine tourism is the small islands tourism such as Gili Matra Islands among others. Small islands tourism is one of the favourite touristic activities because the destination provides beauty, exotism, aesthetic and a diversity of natural habitats including the warm, clear and attractive water. Tourism is being considered as a development instrument in order to boost a country’s economy and has become part of the global industry. However, tourism is also one of the actors that is responsible for environmental depletion, due to the constructions of buildings and tourism activities. This paper aims to study the level of vulnerability in small islands to tourism as a basis of integrated small islands management in Indonesian conservation area. The group of islands in this study consists of three islands namely Gili Ayer Island, Gili Meno Island and Gili Trawangan Island (known as Gili Matra Islands that were observed using Small Islands Vulnerability Index (SIVI. The results indicate that Gili Matra Islands have a vulnerability status from low into moderate, ranging from 2.25 to 2.75. Gili Ayer Island has the highest vulnerability with SIVI of 2.75 (Moderate, followed by Gili Meno Island with SIVI of 2.50 (Low and Gili Trawangan Island with SIVI of 2.25 (Low. The driving factor of vulnerability is the intensive utilization of marine tourism activities. Tourism is the sole stress to Gili Matra Island’s ecosystem due to its direct damaging impact and reducing its environmental quality. The vulnerability index which was built from the coastline, coral reef, live coral reef, and development area was applicable to assess the small island’s vulnerability in Indonesia, especially for coral island.

  8. Social Collaborative Filtering by Trust.

    2017-08-01

    Recommender systems are used to accurately and actively provide users with potentially interesting information or services. Collaborative filtering is a widely adopted approach to recommendation, but sparse data and cold-start users are often barriers to providing high quality recommendations. To address such issues, we propose a novel method that works to improve the performance of collaborative filtering recommendations by integrating sparse rating data given by users and sparse social trust network among these same users. This is a model-based method that adopts matrix factorization technique that maps users into low-dimensional latent feature spaces in terms of their trust relationship, and aims to more accurately reflect the users reciprocal influence on the formation of their own opinions and to learn better preferential patterns of users for high-quality recommendations. We use four large-scale datasets to show that the proposed method performs much better, especially for cold start users, than state-of-the-art recommendation algorithms for social collaborative filtering based on trust.

    2015-12-01

    Full Text Available The purpose of the current paper is to test whether value similarity may foster social trust in society and whether people have higher levels of social trust when they emphasise the same values that prevail in their country. The relationship between social trust and human values was examined in a sample of 51,308 people across 29 European countries using data from the European Social Survey round 6. Results suggest that value similarity is more important in generating individual level social trust in countries where the overall levels of social trust are higher. There is a stronger positive relationship between value similarity and social trust in Scandinavian countries, which have high social trust levels, while in countries with a low level of social trust, congruity of the personal value structure with the country level value structure tends to decrease the individuals trustfulness

  13. Exploring trust relationships during times of change

    Directory of Open Access Journals (Sweden)

    Hartmut Von der Ohe

    2010-10-01

    Research purpose: The objective of this study was to explore the impact of different variables such as demographics on trust relationships in South African organisations. Motivation for the study: Anecdotal evidence and preliminary data collected for a national trust indicator seemed to suggest a shift in trust levels in organisations. Research design: A trust questionnaire was administered to a convenience sample of 307 respondents in all economic sectors. Parametric and nonparametric analyses were used to determine significant differences among economic sectors, job levels and sample periods. Main findings: No significant differences were found for job levels or the different sample periods. However, significant differences were found for the economic sectors and, specifically, between government participants and other sectors for the dimensions of change, team management, organisational trust, information sharing and credibility. Practical implications: In times of change, leadership in organisations need to be aware of the impact on trust levels. It is therefore important that leaders in government focus more on trust-enhancing behaviours needed to repair mistrust in organisations. Contribution: Although the effect of time on trust levels is inconclusive, the clearly differing levels of trust in various economic sectors point to the importance of appropriate and fitting approaches to building trust and not a ‘one-size-fits-all’ attitude.

  15. Who trusts scientists for information about climate change? Nuclear power? Vaccines?

    Science.gov (United States)

    Hamilton, L.

    2015-12-01

    US public acceptance/rejection of science on the topic of climate change has become highly polarized, with a demographic profile well established through survey research. Trust in scientists for information about climate change tends to increase with education, decrease with age, and is higher among self-identified liberals and moderates than among conservatives. Demographic profiles of people who do or do not trust scientists regarding other disputed topics are less well established. Some observers have argued that certain domains such as vaccines, nuclear power or genetically modified organisms (GMOs) could present a mirror image of climate change, with liberals instead of conservatives disproportionately rejecting science on that topic. Evidence for this mirror-image hypothesis has been mainly anecdotal, however. Here we test it systematically using statewide survey data on more than 1200 interviews, comparing five similarly worded questions that ask respondents whether they trust, don't trust, or are unsure about scientists as a source of information about ... climate change, vaccines, evolution, nuclear power safety, or GMOs. Climate change proves to be the most polarized of these topics, but all five exhibit roughly similar age, education and ideological effects -- contrary to the mirror-image hypothesis. The common patterns across five science domains, chosen for their hypothetical contrasts, map out an unexpectedly cohesive picture of who trusts scientists for information, and who does not. Implications of these survey results for public outreach and science communication are explored.

  16. Trust and Society: Suggestions for Further Development of Niklas Luhmann's Theory of Trust.

    Science.gov (United States)

    Morgner, Christian

    2018-05-01

    This paper addresses an apparent gap in the work of Niklas Luhmann. While the issue of trust continues to receive widespread attention in the social sciences, Luhmann's interest in this topic declined following the development of his systems theory. It is argued that this decline does not reflect any diminished relevance of trust for systems theory, but rather that the architectural remodeling of theory cannot easily be applied to the issue of trust. Here, the issue of trust is reconceptualized as a connection medium. This entails a reconstruction of Luhmann's early theory of trust, especially with regard to function and social positioning. In this context, trust can in turn be linked to the concept of medium in Luhmann's late work. As a connection medium, trust mediates between the different levels of sociality-interaction, organization, and society. These theoretical considerations are employed to develop a more applied framework for empirical research, with a brief case study from southern Italy. From this perspective, the idea of trust as society's glue is seen to be overly simplistic. The common ethical understanding that more trust leads to a better society is also questioned on the grounds that social cooperation can also lead to social sclerosis. Finally, risk and trust are shown to accommodate the formation of different cultures of trust. The paper shows how Luhmann's updated version of trust can inspire current research and enhance our understanding of how trust operates in contemporary society. © 2018 Canadian Sociological Association/La Société canadienne de sociologie.

  17. From the general to the specific: How social trust motivates relational trust.

    Robbins, Blaine G

    2016-01-01

    When people form beliefs about the trustworthiness of others with respect to particular matters (i.e., when individuals trust), theory suggests that they rely on preexistent cognitive schemas regarding the general cooperativeness of individuals and organizations (i.e., social trust). In spite of prior work, the impact of social trust on relational trust-or what Russell Hardin (2002) calls trust as a three-part relation where actor A trusts actor B with reference to matter Y-is not well established. Four vignette experiments were administered to Amazon.com Mechanical Turk workers (N = 1388 and N = 1419) and to public university undergraduate students (N = 995 and N = 956) in order to investigate the relationship between social trust and relational trust. Measures of general social trust and particular social trust produced statistically equivalent effects that were positively associated with relational trust. Political trust, however, was statistically unrelated to relational trust. These results support the idea that people rely on schemas and stereotypes concerned with the general cooperativeness and helpfulness of others when forming beliefs about another person's trustworthiness with respect to a particular matter at hand.

  18. Emergent Trust and Work Life Relationships: How to Approach the Relational Moment of Trust

    Directory of Open Access Journals (Sweden)

    Tone Bergljot Eikeland

    2015-10-01

    Full Text Available How do we trust? What does the basic mechanism of trust look like? These questions define the starting point for a comparison of the classic ideas of how trust works by Mayer et al. (1995, Möllering’s (2006 re-adaption of Giddens’, Simmel’s, and James’ classic ideas of trust, and a phenomenological approach focusing on “emergent trust.” Introducing the concept of emergent trust, the idea is to suggest a phenomenological approach to studies of trust in work-life relationships in professional organizations, as an alternative to trust as a cognitive attitude, where trust becomes a stable, individual possession. The term “emergent” demonstrates a trust that emerges in meetings between persons, it has an immediate, unconditional quality, and shows itself in situations of life where there is a potential for trust to appear. Trust’s basic relationality makes the person morally responsible for the other. Trust appears between persons, as an event, constituting risk and uncertainty as a natural and positive part of our lives. Still, in larger social settings, the responsibility of trust also disperses on to the work itself, and our wider social networks.

    2016-11-08

    Trust is important for health at both the individual and societal level. Previous research using Western concepts of trust has shown that a high level of trust in society can positively affect individuals' health; however, it has been found that the concepts and culture of trust in China are different from those in Western countries and research on the relationship between trust and health in China is scarce. The analyses use data from the national scale China General Social Survey (CGSS) on adults aged above 18 in 2005 and 2010. Two concepts of trust ("out-group" and "in-group" trust) are used to examine the relationship between trust and self-rated health in China. Multilevel logistical models are applied, examining the trust at the individual and societal level on individuals' self-rated health. In terms of interpersonal trust, both "out-group" and "in-group" trust are positively associated with good health in 2005 and 2010. At the societal level, the relationships between the two concepts of trust and health are different. In 2005, higher "out-group" social trust (derived from trust in strangers) is positively associated with better health; however, higher "in-group" social trust (derived from trust in most people) is negatively associated with good health in 2010. The cross-level interactions show that lower educated individuals (no education or only primary level), rural residents and those on lower incomes are the most affected groups in societies with higher "out-group" social trust; whereas people with lower levels of educational attainment, a lower income, and those who think that most people can be trusted are the most affected groups in societies with higher "in-group" social trust. High levels of interpersonal trust are of benefit to health. Higher "out-group" social trust is positively associated with better health; while higher "in-group" social trust is negatively associated with good health.

There is evidence that the degree of trust into others might be rather volatile and can be affected by manipulations like drawing attention to personal interdependence or independence. Here we investigated whether the degree of interpersonal trust can be biased by inducing either a more integrative or a more cognitive-control mode by means of a creativity task requiring divergent or convergent thinking, respectively. Participants then performed the Trust Game, which provides an index of interpersonal trust by assessing the money units one participant (the trustor transfers to another participant (the trustee. As expected, participants transferred significantly more money to the trustee after engaging in divergent thinking as compared to convergent thinking. This observation provides support for the idea that interpersonal trust is controlled by domain-general (i.e., not socially dedicated cognitive states.

  2. The Value of Trust to Nursing.

    2014-01-01

    Trust, one of nursing's intangible assets, impacts nurses' ability to form meaningful relationships with patients and this connection positively impacts health outcomes. Linking trust to the fabric of nursing and investing in its measurement will become essential to nursing's valuation and the resulting investment in nursing. Trust, as nursing's core value, should be fostered by nurse educators as they prepare the next generation of nurses. Nurse administrators should connect the trust a patient has for his or her nurse and patient cooperation and honest transparent communication between providers and the patient. Banking trust as a valuable nursing asset will substantiate nursing's marketing and support its worth. Nursing's trustworthiness is an intangible asset that warrants protection, as trust once lost is hard to recapture.

  3. Principals, Trust, and Cultivating Vibrant Schools

    Full Text Available Although principals are ultimately held accountable to student learning in their buildings, the most consistent research results have suggested that their impact on student achievement is largely indirect. Leithwood, Patten, and Jantzi proposed four paths through which this indirect influence would flow, and the purpose of this special issue is to examine in greater depth these mediating variables. Among mediating variables, we assert that trust is key. In this paper, we explore the evidence that points to the role that faculty trust in the principal plays in student learning and how principals can cultivate trust by attending to the five facets of trust, as well as the correlates of trust that mediate student learning, including academic press, collective teacher efficacy, and teacher professionalism. We argue that trust plays a role in each of the four paths identified by Leithwood, Patten, and Jantzi. Finally, we explore possible new directions for future research.

    Conservation of current and conservation of charge are nearly the same thing: when enough is known about charge movement, conservation of current can be derived from conservation of charge, in ideal dielectrics, for example. Conservation of current is enforced implicitly in ideal dielectrics by theories that conserve charge. But charge movement in real materials like semiconductors or ionic solutions is never ideal. We present an apparently universal derivation of conservation of current and ...

    The major healt effect of the accident at Three Mile Island was that of a pronounced demoralizing effect on the general population living in the Three Mile Island area, including teenagers and mothers of preschool children, and the nuclear plant workers. However, this effect has proved transient in all groups studied except the nuclear workers, who continued to show relatively high levels of demoralization some months after the accident. Moreover, the groups in the general population and the workers, in their differen ways, had continuing problems of trust that stemmed directly from the Three Mile Island accident. For both the nuclear workers and general population, the mental health and behavioral effects are understandable in terms of the objective realities of the threats they faced during the nuclear accident at Three Mile Island

  13. Sensory Metrics of Neuromechanical Trust.

    Science.gov (United States)

    Softky, William; Benford, Criscillia

    2017-09-01

    Today digital sources supply a historically unprecedented component of human sensorimotor data, the consumption of which is correlated with poorly understood maladies such as Internet addiction disorder and Internet gaming disorder. Because both natural and digital sensorimotor data share common mathematical descriptions, one can quantify our informational sensorimotor needs using the signal processing metrics of entropy, noise, dimensionality, continuity, latency, and bandwidth. Such metrics describe in neutral terms the informational diet human brains require to self-calibrate, allowing individuals to maintain trusting relationships. With these metrics, we define the trust humans experience using the mathematical language of computational models, that is, as a primitive statistical algorithm processing finely grained sensorimotor data from neuromechanical interaction. This definition of neuromechanical trust implies that artificial sensorimotor inputs and interactions that attract low-level attention through frequent discontinuities and enhanced coherence will decalibrate a brain's representation of its world over the long term by violating the implicit statistical contract for which self-calibration evolved. Our hypersimplified mathematical understanding of human sensorimotor processing as multiscale, continuous-time vibratory interaction allows equally broad-brush descriptions of failure modes and solutions. For example, we model addiction in general as the result of homeostatic regulation gone awry in novel environments (sign reversal) and digital dependency as a sub-case in which the decalibration caused by digital sensorimotor data spurs yet more consumption of them. We predict that institutions can use these sensorimotor metrics to quantify media richness to improve employee well-being; that dyads and family-size groups will bond and heal best through low-latency, high-resolution multisensory interaction such as shared meals and reciprocated touch; and

    Science.gov (United States)

    Tams, Stefan

    We examine the relative and complementary effectiveness of trust-building strategies in online environments. While prior research has examined various antecedents to trust, we investigated two trust-building mechanisms more in depth: Web site trust and vendor reputation. We tried to understand the relative effectiveness of these two important mechanisms to provide online businesses with a clear recommendation of how to establish trust in an effective and efficient manner. Drawing from the literature on trust, we proposed vendor reputation to be more effective than Web site trust. Moreover, we examined a potential complementary effect of these mechanisms so as to provide online businesses with a deeper understanding of how to derive superior trust. We hypothesize a small such effect. The study proposes a laboratory experiment to test the model.

  1. On Propagating Interpersonal Trust in Social Networks

    Science.gov (United States)

    Ziegler, Cai-Nicolas

    The age of information glut has fostered the proliferation of data and documents on the Web, created by man and machine alike. Hence, there is an enormous wealth of minable knowledge that is yet to be extracted, in particular, on the Semantic Web. However, besides understanding information stated by subjects, knowing about their credibility becomes equally crucial. Hence, trust and trust metrics, conceived as computational means to evaluate trust relationships between individuals, come into play. Our major contribution to Semantic Web trust management through this work is twofold. First, we introduce a classification scheme for trust metrics along various axes and discuss advantages and drawbacks of existing approaches for Semantic Web scenarios. Hereby, we devise an advocacy for local group trust metrics, guiding us to the second part, which presents Appleseed, our novel proposal for local group trust computation. Compelling in its simplicity, Appleseed borrows many ideas from spreading activation models in psychology and relates their concepts to trust evaluation in an intuitive fashion. Moreover, we provide extensions for the Appleseed nucleus that make our trust metric handle distrust statements.

This limits the portability and mobility of trust as demanded by many emerging applications that go beyond the organizational boundaries. In order to address this problem, we propose a mobile and portable trusted computing platform in a form of a USB device. First, we describe the design and implementation of the hardware and software architectures of the device. We then demonstrate the capabilities of the proposed device by developing a trusted application.

Trust quantification is thus an important issue in dynamic trust management. By considering the fuzziness and uncertainty of trust, in this paper, we propose a fuzzy comprehensive evaluation method to quantify trust along with a trust quantification algorithm. Simulation results show that the trust quantification algorithm that we propose can effectively quantify trust and the quantified value of an entity's trust is consistent with the behavior of the entity.

    Hoff, Kevin Anthony; Bashir, Masooda

    2015-05-01

    We systematically review recent empirical research on factors that influence trust in automation to present a three-layered trust model that synthesizes existing knowledge. Much of the existing research on factors that guide human-automation interaction is centered around trust, a variable that often determines the willingness of human operators to rely on automation. Studies have utilized a variety of different automated systems in diverse experimental paradigms to identify factors that impact operators' trust. We performed a systematic review of empirical research on trust in automation from January 2002 to June 2013. Papers were deemed eligible only if they reported the results of a human-subjects experiment in which humans interacted with an automated system in order to achieve a goal. Additionally, a relationship between trust (or a trust-related behavior) and another variable had to be measured. All together, 101 total papers, containing 127 eligible studies, were included in the review. Our analysis revealed three layers of variability in human-automation trust (dispositional trust, situational trust, and learned trust), which we organize into a model. We propose design recommendations for creating trustworthy automation and identify environmental conditions that can affect the strength of the relationship between trust and reliance. Future research directions are also discussed for each layer of trust. Our three-layered trust model provides a new lens for conceptualizing the variability of trust in automation. Its structure can be applied to help guide future research and develop training interventions and design procedures that encourage appropriate trust. © 2014, Human Factors and Ergonomics Society.

  8. Dimensionality of trust: An analysis of the relations between propensity, trustworthiness and trust

    Marita Heyns

    2015-05-01

    Research purpose: This study examined the dynamic interplay between trust propensity, trustworthiness beliefs and the decision to trust, as perceived within dyadic workplace relationships. Motivation for the study: No studies, as far as the authors are aware, have ever attempted to use a combination of Mayer and Davis’s well-known assessment of trustworthiness and Gillespie’s measure of behavioural trust within the same study. By including measures of main antecedents and the actual decision to trust in the same study, the multidimensionality of trust can be established more concretely. Research approach, design and method: A cross-sectional survey design with a convenience sample (N = 539 was used. The Behavioural Trust Inventory and the Organisational Trust Instrument were administered. Main findings: Results confirmed the distinctness of propensity, trustworthiness and trust as separate main constructs. Trust was strongly associated with trustworthiness beliefs. Trustworthiness beliefs fully mediated the relationship between propensity and trust. The observed relations between propensity and trustworthiness suggest that individuals with a natural predisposition to trust others will be more inclined to perceive a specific trust referent as trustworthy. Practical/managerial implications: Leaders should realise that their attitudes and behaviour have a decisive impact on trust formation processes: if they are being perceived as trustworthy, followers will be likely to respond by engaging in trusting behaviours towards them. Tools to assess followers’ perceptions of the trustworthiness of the leader may provide useful feedback that can guide leaders. Contribution/value-add: This study contributes to scientific knowledge regarding the influence of propensity to trust and trustworthiness on trust of leaders.

  13. Trust and automation: the influence of automation malfunctions and system feedback on operator trust

    International Nuclear Information System (INIS)

    Strand, Stine

    2001-10-01

    Level of operator trust in an automatic system, which is not in accordance with the reliability of the system, might impose serious threats concerning issues of safety, productivity and the well being of the operator. Operator trust is therefore regarded as an important variable in man-machine interaction. The focus of this study was the influence of automatic malfunctions and amount of feedback provided by the automatic system on level of operator trust. The study was conducted in conjunction with the Human Centred Automation 2000-experiment. Two questionnaires attempting to measure operator trust were developed, designed to reflect the dimensions of predictability, dependability and faith. Analysis of the questionnaires demonstrated that they were reliable tools for measurement of operator trust. Factor analysis did not completely confirm the theoretical dimensions of trust, but indicated partial support. Operator trust correlated negatively with workload across situations, and positively with performance in complex situations. The results of the hypotheses tests demonstrated that operator trust gradually decreased after introduction of malfunctions. The effect of different malfunctions was however the opposite of what was expected, with obvious malfunctions reducing trust more than more camouflaged and safety critical malfunctions. Trust in the automatic system in general was lower than trust in specific malfunctioning components. Different interfaces providing different amount of feedback to the operator did not significantly influence level of operator trust. (Author)

    The after-effect of Monju and Tokai accidents has been much larger than expected. It struck PNC a fierce blow and the damage did not stop there but extended to the nuclear community at large. As a result, PNC was reformed into a new corporate, Japan Nuclear Cycle Development Institute (JNC). JNC has been given a new body but its mind must be cultivated so as to be able to regain public trust. This presentation summarizes the struggle to regain public trust in case of Monju. After five and a half years of construction work, Monju began pre-operation tests in May 1991, achieved initial criticality in April 1994 and the first connection to the grid in August 1995, and the accident occurs in December 1995. Until then, there was confidence, perhaps overconfidence, and it was taken for granted that the public was always in favour of 'nuclear'. The struggle to regain the public confidence involved: (1) Improvement of safety measures and emergency management; (2) Cultivation of a new corporate culture; (3) Open information; (4) Public communication (i.e. 'Door-to-door visit', 'Public meeting', 'Come-and-see', Weekly press conference.

    2012-01-01

    With the growing popularity of online social network,trust plays a more and more important role in connecting people to each other.We rely on our personal trust to accept recommendations,to make purchase decisions and to select transaction partners in the online community.Therefore,how to obtain trust relationships through mining online social networks becomes an important research topic.There are several shortcomings of existing trust mining methods.First,trust is category-dependent.However,most of the methods overlook the category attribute of trust relationships,which leads to low accuracy in trust calculation.Second,since the data in online social networks cannot be understood and processed by machines directly,traditional mining methods require much human effort and are not easily applied to other applications.To solve the above problems,we propose a semantic-based trust reasoning mechanism to mine trust relationships from online social networks automatically.We emphasize the category attribute of pairwise relationships and utilize Semantic Web technologies to build a domain ontology for data communication and knowledge sharing.We exploit role-based and behavior-based reasoning functions to infer implicit trust relationships and category-specific trust relationships.We make use of path expressions to extend reasoning rules so that the mining process can be done directly without much human effort.We perform experiments on real-life data extracted from Epinions.The experimental results verify the effectiveness and wide application use of our proposed method.

  19. An Efficient Dynamic Trust Evaluation Model for Wireless Sensor Networks

    Directory of Open Access Journals (Sweden)

    Zhengwang Ye

    2017-01-01

    Full Text Available Trust evaluation is an effective method to detect malicious nodes and ensure security in wireless sensor networks (WSNs. In this paper, an efficient dynamic trust evaluation model (DTEM for WSNs is proposed, which implements accurate, efficient, and dynamic trust evaluation by dynamically adjusting the weights of direct trust and indirect trust and the parameters of the update mechanism. To achieve accurate trust evaluation, the direct trust is calculated considering multitrust including communication trust, data trust, and energy trust with the punishment factor and regulating function. The indirect trust is evaluated conditionally by the trusted recommendations from a third party. Moreover, the integrated trust is measured by assigning dynamic weights for direct trust and indirect trust and combining them. Finally, we propose an update mechanism by a sliding window based on induced ordered weighted averaging operator to enhance flexibility. We can dynamically adapt the parameters and the interactive history windows number according to the actual needs of the network to realize dynamic update of direct trust value. Simulation results indicate that the proposed dynamic trust model is an efficient dynamic and attack-resistant trust evaluation model. Compared with existing approaches, the proposed dynamic trust model performs better in defending multiple malicious attacks.

    Full Text Available A major goal of ideological education in China is to promote loyalty to the party-state and to instill atheism among the people. How effective is this ideological education? This article examines the relationship between education and trust in government and trust in religion using data from the 2010 Chinese General Social Survey. We find that education is negatively associated with trust in government, while positively related to trust in religion. Our findings suggest that policies aimed at displacing religion in favor of the Communist ideology have largely failed to shape the public mindset; rather, the more educated, the more people tend to trust religion instead of the government.

    The purpose of this paper is to identify managerial and organizational characteristics and behaviors that facilitate the fostering of a just and trusting culture within the healthcare system. Two studies were conducted. The initial qualitative one was used to identify themes based on interviews with health care workers that facilitate a just and trusting culture. The quantitative one used a policy-capturing design to determine which factors were most likely to predict outcomes of manager and organizational trust. The factors of violation type (ability vs integrity), providing an explanation or not, blame vs no blame by manager, and blame vs no blame by organization were all significant predictors of perceptions of trust. Limitations to the generalizability of findings included both a small and non-representative sample from one health care region. The present findings can be useful in developing training systems for managers and organizational executive teams for managing medical error events in a manner that will help develop a just and trusting culture. A just and trusting culture should enhance the likelihood of reporting medical errors. Improved reporting, in turn, should enhance patient safety. This is the first field study experimentally manipulating aspects of organizational trust within the health care sector. The use of policy-capturing is a unique feature that sheds light into the decision-making of health care workers as to the efficaciousness of particular managerial and organizational characteristics that impact a just and trusting culture.

    People behave and interact with others differently when experiencing physical pain. Pain has dramatic effects on one's emotional responses, cognitive functions and social interaction. However, little has been known about whether and how physical pain influences interpersonal trust in social interaction. In the present study, we examined the influence of physical pain on trusting behaviour. A total of 112 healthy participants were recruited and assigned to physical pain condition (induced by Capsaicin) and control condition (with hand cream), respectively. Thirty minutes after pain induction, three decision-making tasks were conducted to measure behaviours in social interaction, including trust and trustworthiness (trust game), non-social risk-taking (risk game) and altruism (dictator game). Results showed that physical pain increased interpersonal trust among females, but not among males. Pain did not influence non-social risk-taking, altruism or trustworthiness, as evaluated by monetary transfers in those tasks. Moreover, the effect of physical pain on interpersonal trust was fully mediated by expectation of monetary profit. These findings demonstrate an effect of pain on interpersonal trust and suggest a reciprocity mechanism that the effect may be driven by self-interest rather than altruistic motivation. The pain effect on trust was evident only in females, implying distinct pain coping strategies used by both genders. The present work highlights the social component of pain and extends our understanding of mutual interactions between pain and social cognition. © 2017 European Pain Federation - EFIC®.

    Full Text Available In this paper the author deals with the concept of social trust. It is the author’s view that this concept has been neglected in past political science research in Croatia; consequently, he wishes to present it to the academic and professional political science public, thus creating a basis for its future use. Moreover, through application of a secondary dana analysis the author describes the state of social trust in Croatia. First, he contextualises the concept of social trust with regard to the dominant research approaches in political science; then he points to the distinctiveness of social trust in relation to other types of trust; fi nally, he provides an overview of the most relevant works on the importance and functions of social trust. In the concluding part of the paper, an analysis of the levels of social trust is conducted, revealing that Croatia is a society with markedly low levels of social trust. In the author’s opinion, this could present an obstacle to further political and economic development.

    Full Text Available Facilitation of growth is more about good, trustworthy contacts than capital. Trust is a driving force for business creation, and to create a global business you need to build a team that is capable of meeting the challenge. Trust is a key factor in team building and a needed enabler for cooperation. In general, trust building is a slow process, but it can be accelerated with open interaction and good communication skills. The fast-growing and ever-changing nature of global business sets demands for cooperation and team building, especially for startup companies. Trust building needs personal knowledge and regular face-to-face interaction, but it also requires empathy, respect, and genuine listening. Trust increases communication, and rich and open communication is essential for the building of high-performing teams. Other building materials are a shared vision, clear roles and responsibilities, willingness for cooperation, and supporting and encouraging leadership. This study focuses on trust in high-performing teams. It asks whether it is possible to manage trust and which tools and operation models should be used to speed up the building of trust. In this article, preliminary results from the authors’ research are presented to highlight the importance of sharing critical information and having a high level of communication through constant interaction.

    Invasive alien species are one of the primary threats to native biodiversity on islands worldwide. Consequently, eradicating invasive species from islands has become a mainstream conservation practice. Deciding which islands have the highest priority for eradication is of strategic importance to allocate limited resources to achieve maximum conservation benefit. Previous island prioritizations focused either on a narrow set of native species or on a small geographic area. We devised a prioritization approach that incorporates all threatened native terrestrial vertebrates and all invasive terrestrial vertebrates occurring on 11 U.K. overseas territories, which comprise over 2000 islands ranging from the sub-Antarctic to the tropics. Our approach includes eradication feasibility and distinguishes between the potential and realistic conservation value of an eradication, which reflects the benefit that would accrue following eradication of either all invasive species or only those species for which eradication techniques currently exist. We identified the top 25 priority islands for invasive species eradication that together would benefit extant populations of 155 native species including 45 globally threatened species. The 5 most valuable islands included the 2 World Heritage islands Gough (South Atlantic) and Henderson (South Pacific) that feature unique seabird colonies, and Anegada, Little Cayman, and Guana Island in the Caribbean that feature a unique reptile fauna. This prioritization can be rapidly repeated if new information or techniques become available, and the approach could be replicated elsewhere in the world. © 2014 Crown copyright.

    Trust is the essence of human social existence. From the moment of birth, trust is the basic component in any human relationship and interaction. Trust is the Holy Grail for human confidence in others. From human survival to organizational survival, trust is the primordial bond. No organization is more dependent on trust than health care. This article views trust as the most basic fundamental quality for leadership. Trust is a sublime duty of a leader and the leadership of an organization. Leadership sets the culture of trust. Trust is the one quality that is essential for guiding an organization toward serving others. This article addresses trust from many perspectives. Trust is viewed from our subordinates, our peers, our superiors, and the public we serve. This article postulates how trust in an organization is the sublime duty of leadership that unites all human understanding and without it destroys all human relationships.

It has been built a scale to measure the disposition to trust and the relationship has beenexamined among naïve and wise attitude when trusting. The sample was constituted by 575 universitystudents of both sexes, of four faculties and of different years of study. Through a factorial analysis itwas found that trust and distrust correspond to different factors. It was discussed the importance ofincrease an optimal trust in order to develop social abilities and to stimulate the social participation. Itwas questioned the validity of traditional surveys that measure the social trust.

    Direct-to-consumer (DTC) prescription drug brand websites, as a form of DTC advertising, are receiving increasing attention due to the growing number and importance as an ad and a consumer information source. This study examined consumer trust in a DTC website as an important factor influencing consumers' attitude toward the website and behavioral intention. Applying the conceptual framework of website trust, the particular focus of investigation was the effect of the website trust cue factor on consumers' perceived DTC website trust and subsequent attitudinal and behavioral responses. Results show a significant relation between the website trust cue factor and consumers' perceived DTC website trust. Perceived DTC website trust, in turn, was found to be significantly associated with consumers' attitude toward the DTC website and behavioral intention.

  18. Robust Trust in Expert Testimony

    Directory of Open Access Journals (Sweden)

    Christian Dahlman

    2015-05-01

    Full Text Available The standard of proof in criminal trials should require that the evidence presented by the prosecution is robust. This requirement of robustness says that it must be unlikely that additional information would change the probability that the defendant is guilty. Robustness is difficult for a judge to estimate, as it requires the judge to assess the possible effect of information that the he or she does not have. This article is concerned with expert witnesses and proposes a method for reviewing the robustness of expert testimony. According to the proposed method, the robustness of expert testimony is estimated with regard to competence, motivation, external strength, internal strength and relevance. The danger of trusting non-robust expert testimony is illustrated with an analysis of the Thomas Quick Case, a Swedish legal scandal where a patient at a mental institution was wrongfully convicted for eight murders.

    Penders, Bart

    2018-03-01

    Academic misconduct distorts the relationship between scientific practice and the knowledge it produces. The relationship between science and the knowledge it produces is, however, not something universally agreed upon. In this paper I will critically discuss the moral status of an act of research misconduct, namely plagiarism, in the context of different epistemological positions. While from a positivist view of science, plagiarism only influences trust in science but not the content of the scientific corpus, from a constructivist point of view both are at stake. Consequently, I argue that discussions of research misconduct and responsible research ought to be explicitly informed by the authors' views on the relationship between science and the knowledge it produces.

    The Diomede Islands consisting of the western island Big Diomede (also known as Imaqliq, Nunarbuk or Ratmanov Island), and the eastern island Little Diomede (also known as Krusenstern Island or Inaliq), are two rocky islands located in the middle of the Bering Strait between Russia and Alaska. The islands are separated by an international border and the International Date Line which is approximately 1.5 km from each island; you can look from Alaska into tomorrow in Russia. At the closest land approach between the United States, which controls Little Diomede, and Russia, which controls Big Diomede, they are 3 km apart. Little Diomede Island constitutes the Alaskan City of Diomede, while Big Diomede Island is Russia's easternmost point. The first European to reach the islands was the Russian explorer Semyon Dezhnev in 1648. The text of the 1867 treaty finalizing the sale of Alaska uses the islands to designate the border between the two nations. The image was acquired July 8, 2000, covers an area of 13.5 x 10.8 km, and is located at 65.8 degrees north latitude, 169 degrees west longitude.

    Tropical reefs and beaches attract hordes of tourists from temperature zones. These environments may be the most valuable resource of small island nations, providing fish, coastal protection and support for a tourist industry. However, tourism can strain the resource base resulting in damage to habitat's from intensified fishing activity and the depletion of species through over exploitation. Conflict develops between subsistence requirements of local residents, the recreational demands of tourists and conservation constraints. When included in national development planning, the establishment of conservation areas can help reduce conflicts through zoning for different uses the protected areas. This enable the grouping of compatible activities into specific zones and the separation of those which are incompatible. This paper discusses the planning of protected areas which have tourism as a major component, drawing on two case studies in Indonesia.

    Tropical reefs and beaches attract hordes of tourists from temperature zones. These environments may be the most valuable resource of small island nations, providing fish, coastal protection and support for a tourist industry. However, tourism can strain the resource base resulting in damage to habitat's from intensified fishing activity and the depletion of species through over exploitation. Conflict develops between subsistence requirements of local residents, the recreational demands of tourists and conservation constraints. When included in national development planning, the establishment of conservation areas can help reduce conflicts through zoning for different uses the protected areas. This enable the grouping of compatible activities into specific zones and the separation of those which are incompatible. This paper discusses the planning of protected areas which have tourism as a major component, drawing on two case studies in Indonesia. Some techniques are listed for controlling visitor use of protected areas.

  6. REVIEW: The evolving linkage between conservation science and practice at The Nature Conservancy.

    The Nature Conservancy (TNC) was founded by ecologists as a United States land trust to purchase parcels of habitat for the purpose of scientific study. It has evolved into a global organization working in 35 countries 'to conserve the lands and waters on which all life depends'. TNC is now the world 's largest conservation non-governmental organization (NGO), an early adopter of advances in ecological theory and a producer of new science as a result of practising conservation.The Nature Conservancy 's initial scientific innovation was the use of distributional data for rare species and ecological communities to systematically target lands for conservation. This innovation later evolved into a more rigorous approach known as 'Conservation by Design' that contained elements of systematic conservation planning, strategic planning and monitoring and evaluation.The next scientific transition at TNC was a move to landscape-scale projects, motivated by ideas from landscape ecology. Because the scale at which land could be set aside in areas untouched by humans fell far short of the spatial scale demanded by conservation, TNC became involved with best management practices for forestry, grazing, agriculture, hydropower and other land uses.A third scientific innovation at TNC came with the pursuit of multiobjective planning that accounts for economic and resource needs in the same plans that seek to protect biodiversity.The Millennium Ecosystem Assessment prompted TNC to become increasingly concerned with ecosystem services and the material risk to people posed by ecosystem deterioration.Finally, because conservation depends heavily upon negotiation, TNC has recently recruited social scientists, economists and communication experts. One aspect still missing, however, is a solid scientific understanding of thresholds that should be averted. Synthesis and applications . Over its 60-plus year history, scientific advances have informed The Nature Conservancy (TNC) 's actions

    The author looks at diverse concepts and roles of trust in the challenge of decarbonising energy systems, drawing on 25 years of personal experience in the fields of energy and environmental policy research. The paper focuses on three issues-public trust in science, institutional trust in making technology choices, and the idea that high-trust societies are more sustainable than those exhibiting low-trust. While trust is a key concept in understanding the public acceptability of technology choices, it is only one of a suite of interrelated concepts that must be addressed, which also includes liability, consent, and fairness. Furthermore, rational distrust among competing institutional world views may be critical in understanding the role of social capital in socioeconomic and technological development. Thus the concept of trust has become a portmanteau, carrying a diverse range of ideas and conditions for sustainable energy systems. The paper concludes with three emphases for decision makers. First, the issue is the energy system, not particular generating technologies. Second, the energy system must be recognized to be as much a social system as it is a technical one. Third, the system requires incorporation of the minimum level of diversity of engineering technologies and social actors to be sustainable. (author)

    1997-02-01

    Patients' trust in their physicians has recently become a focus of concern, largely owing to the rise of managed care, yet the subject remains largely unstudied. We undertook a qualitative research study of patients' self-reported experiences with trust in a physician to gain further understanding of the components of trust in the context of the patient-physician relationship. Twenty-nine patients participants, aged 26 to 72, were recruited from three diverse practice sites. Four focus groups, each lasting 1.5 to 2 hours, were conducted to explore patients' experiences with trust. Focus groups were audio-recorded, transcribed, and coded by four readers, using principles of grounded theory. The resulting consensus codes were grouped into seven categories of physician behavior, two of which related primarily to technical competence (thoroughness in evaluation and providing appropriate and effective treatment) and five of which were interpersonal (understanding patient's individual experience, expressing caring, communicating clearly and completely, building partnership/sharing power and honesty/respect for patient). Two additional categories were predisposing factors and structural/staffing factors. Each major category had multiple subcategories. Specific examples from each major category are provided. These nine categories of physician behavior encompassed the trust experiences related by the 29 patients. These categories and the specific examples provided by patients provide insights into the process of trust formation and suggest ways in which physicians could be more effective in building and maintaining trust.

    Trust in providers has been in decline in recent decades. This study attempts to identify sources of trust in characteristics of health care systems and the wider community. The design is cross-sectional. Data are from (1) the 1996 Household Survey of the Community Tracking Study, drawn from 24 Metropolitan Statistical Areas; (2) a 1996 multi-city broadcast media marketing database including key social capital indicators; (3) Interstudy; (4) the American Hospital Association; and (5) the American Medical Association. Independent variables include individual socio-demographic variables, HMO enrollment, community-level health sector variables, and social capital. The dependent variable is self-reported trust in physicians. Data are merged from the various sources and analyzed using SUDAAN. Subjects include adults in the Household Survey who responded to the items on trust in physicians (N=17,653). Trust in physicians is independently predicted by community social capital (pSocial capital plays a role in how health care is perceived by citizens, and how health care is delivered by providers. Efforts to build trust and collaboration in a community may improve trust in physicians, health care quality, access, and preserve local health care control.

  10. Recommendation based on trust diffusion model.

    Recommender system is emerging as a powerful and popular tool for online information relevant to a given user. The traditional recommendation system suffers from the cold start problem and the data sparsity problem. Many methods have been proposed to solve these problems, but few can achieve satisfactory efficiency. In this paper, we present a method which combines the trust diffusion (DiffTrust) algorithm and the probabilistic matrix factorization (PMF). DiffTrust is first used to study the possible diffusions of trust between various users. It is able to make use of the implicit relationship of the trust network, thus alleviating the data sparsity problem. The probabilistic matrix factorization (PMF) is then employed to combine the users' tastes with their trusted friends' interests. We evaluate the algorithm on Flixster, Moviedata, and Epinions datasets, respectively. The experimental results show that the recommendation based on our proposed DiffTrust + PMF model achieves high performance in terms of the root mean square error (RMSE), Recall, and F Measure.

  12. Hype and public trust in science.

    Master, Zubin; Resnik, David B

    2013-06-01

    Social scientists have begun elucidating the variables that influence public trust in science, yet little is known about hype in biotechnology and its effects on public trust. Many scholars claim that hyping biotechnology results in a loss of public trust, and possibly public enthusiasm or support for science, because public expectations of the biotechnological promises will be unmet. We argue for the need for empirical research that examines the relationships between hype, public trust, and public enthusiasm/support. We discuss the complexities in designing empirical studies that provide evidence for a causal link between hype, public trust, and public enthusiasm/support, but also illustrate how this may be remedied. Further empirical research on hype and public trust is needed in order to improve public communication of science and to design evidence-based education on the responsible conduct of research for scientists. We conclude that conceptual arguments made on hype and public trust must be nuanced to reflect our current understanding of this relationship.

  13. Genetic influences are virtually absent for trust.

    Directory of Open Access Journals (Sweden)

    Paul A M Van Lange

    Full Text Available Over the past decades, numerous twin studies have revealed moderate to high heritability estimates for individual differences in a wide range of human traits, including cognitive ability, psychiatric disorders, and personality traits. Even factors that are generally believed to be environmental in nature have been shown to be under genetic control, albeit modest. Is such heritability also present in social traits that are conceptualized as causes and consequences of social interactions or in other ways strongly shaped by behavior of other people? Here we examine a population-based sample of 1,012 twins and relatives. We show that the genetic influence on generalized trust in other people (trust-in-others: h2 = 5%, ns, and beliefs regarding other people's trust in the self (trust-in-self: h2 = 13%, ns, is virtually absent. As test-retest reliability for both scales were found to be moderate or high (r = .76 and r = .53, respectively in an independent sample, we conclude that all variance in trust is likely to be accounted for by non-shared environmental influences. We show that, relative to cognitive abilities, psychiatric disorders, and classic personality variables, genetic influences are smaller for trust, and propose that experiences with or observations of the behavior of other people shape trust more strongly than other traits.

    2018-04-01

    To measure public trust in a health information sharing in a broadly defined health system (system trust), inclusive of health care, public health, and research; to identify individual characteristics that predict system trust; and to consider these findings in the context of national health initiatives (e.g., learning health systems and precision medicine) that will expand the scope of data sharing. Survey data (n = 1,011) were collected in February 2014. We constructed a composite index of four dimensions of system trust-competency, fidelity, integrity, and trustworthiness. The index was used in linear regression evaluating demographic and psychosocial predictors of system trust. Data were collected by GfK Custom using a nationally representative sample and analyzed in Stata 13.0. Our findings suggest the public's trust may not meet the needs of health systems as they enter an era of expanded data sharing. We found that a majority of the U.S. public does not trust the organizations that have health information and share it (i.e., the health system) in one or more dimensions. Together, demographic and psychosocial factors accounted for ~18 percent of the observed variability in system trust. Future research should consider additional predictors of system trust such as knowledge, attitudes, and beliefs to inform policies and practices for health data sharing. © Health Research and Educational Trust.

    2016-01-01

    Theories suggest that political ideology relates to cooperation, with conservatives being more likely to pursue selfish outcomes, and liberals more likely to pursue egalitarian outcomes. In study 1, we examine how political ideology and political party affiliation (Republican vs. Democrat) predict cooperation with a partner who self-identifies as Republican or Democrat in two samples before (n = 362) and after (n = 366) the 2012 US presidential election. Liberals show slightly more concern for their partners’ outcomes compared to conservatives (study 1), and in study 2 this relation is supported by a meta-analysis (r = .15). However, in study 1, political ideology did not relate to cooperation in general. Both Republicans and Democrats extend more cooperation to their in-group relative to the out-group, and this is explained by expectations of cooperation from in-group versus out-group members. We discuss the relation between political ideology and cooperation within and between groups. PMID:29593363

  2. Analysis on trust influencing factors and trust model from multiple perspectives of online Auction

    Current reputation models lack the research on online auction trading completely so they cannot entirely reflect the reputation status of users and may cause problems on operability. To evaluate the user trust in online auction correctly, a trust computing model based on multiple influencing factors is established. It aims at overcoming the efficiency of current trust computing methods and the limitations of traditional theoretical trust models. The improved model comprehensively considers the trust degree evaluation factors of three types of participants according to different participation modes of online auctioneers, to improve the accuracy, effectiveness and robustness of the trust degree. The experiments test the efficiency and the performance of our model under different scale of malicious user, under environment like eBay and Sporas model. The experimental results analysis show the model proposed in this paper makes up the deficiency of existing model and it also has better feasibility.

  3. Do Reputation Systems Undermine Trust? Divergent Effects of Enforcement Type on Generalized Trust and Trustworthiness.

    Science.gov (United States)

    Kuwabara, Ko

    2015-03-01

    Research shows that enforcing cooperation using contracts or tangible sanctions can backfire, undermining people's intrinsic motivation to cooperate: when the enforcement is removed, people are less trusting or trustworthy than when there is no enforcement to begin with. The author examines whether reputation systems have similar consequences for generalized trust and trustworthiness. Using a web-based experiment simulating online market transactions (studies 1 and 2), he shows that reputation systems can reinforce generalized trust and trustworthiness, unlike contractual enforcement or relational enforcement based on repeated interactions. In a survey experiment (study 3), he finds that recalling their eBay feedback scores made participants more trusting and trustworthy. These results are predicated on the diffuse nature of reputational enforcement to reinforce perceptions of trust and trustworthiness. These results have implications for understanding how different forms of governance affect generalized trust and trustworthiness.

  4. DualTrust: A Trust Management Model for Swarm-Based Autonomic Computing Systems

    Energy Technology Data Exchange (ETDEWEB)

    Maiden, Wendy M. [Washington State Univ., Pullman, WA (United States)

    2010-05-01

    Trust management techniques must be adapted to the unique needs of the application architectures and problem domains to which they are applied. For autonomic computing systems that utilize mobile agents and ant colony algorithms for their sensor layer, certain characteristics of the mobile agent ant swarm -- their lightweight, ephemeral nature and indirect communication -- make this adaptation especially challenging. This thesis looks at the trust issues and opportunities in swarm-based autonomic computing systems and finds that by monitoring the trustworthiness of the autonomic managers rather than the swarming sensors, the trust management problem becomes much more scalable and still serves to protect the swarm. After analyzing the applicability of trust management research as it has been applied to architectures with similar characteristics, this thesis specifies the required characteristics for trust management mechanisms used to monitor the trustworthiness of entities in a swarm-based autonomic computing system and describes a trust model that meets these requirements.

  5. Paradise Islands? Island States and Environmental Performance

    Sverker C. Jagers

    2016-03-01

    Full Text Available Island states have been shown to outperform continental states on a number of large-scale coordination-related outcomes, such as levels of democracy and institutional quality. The argument developed and tested in this article contends that the same kind of logic may apply to islands’ environmental performance, too. However, the empirical analysis shows mixed results. Among the 105 environmental outcomes that we analyzed, being an island only has a positive impact on 20 of them. For example, island states tend to outcompete continental states with respect to several indicators related to water quality but not in aspects related to biodiversity, protected areas, or environmental regulations. In addition, the causal factors previously suggested to make islands outperform continental states in terms of coordination have weak explanatory power in predicting islands’ environmental performance. We conclude the paper by discussing how these interesting findings can be further explored.

    The USAPI has a population of about 1,800,000 people spread across 4.9 million square miles of the Pacific Ocean. The Pacific Islands are characterized by a multitude of indigenous cultures and languages. English is the common language of instruction in all jurisdictions, but is not the language spoken at home for most students outside of Hawai'i. Many USAPI students live considerably below the poverty line. The Pacific Island region is projected to experience some of the most profound negative impacts considerably sooner than other regions. Funded by the National Science Foundation, the Pacific Islands Climate Education Partnership (PCEP) aims to educate the region's students and citizens in ways that exemplify modern science and indigenous environmental knowledge, address the urgency of climate change impacts, and honor indigenous cultures. Students and citizens within the region will have the knowledge and skills to advance their and our understanding of climate change, and to adapt to its impacts. PCEP has developed a regional network, tools, and an emerging plan to systemically transform K-14 climate education in the USAPI. More than 50 organizations and networks have joined the partnership. These partners include all of the region's state departments of education, major universities, and community colleges, and a wide range of local partners, particularly conservation organizations. One of PCEP's major tools is general, multidisciplinary K-14 climate science education framework that organizes major underlying concepts and skills within appropriate grade-span progressions. This framework is based largely upon prior national science and climate literacy work and the National Research Council's recent document "A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas." The PCEP climate education framework has an Earth System Science foundation that is directly applicable in all locations, and it also has orientations that are
