    2010-01-01

    The purpose of this paper is to show that conceptualizing trust and control as interactively related processes, as opposed to more static conceptualizations of the two concepts and the relations between them, adds importantly towards understanding the challenges involved in balancing of trust...... and control in organizations. The paper examines recent literature on the conceptualization of the relation between trust and control in and between organizations. The literature review shows that trust and control has been conceptualized as either substituting or complementing each other. Further......, it is found that the complementary/substitution debate calls for an explicit conceptualization of the relation between trust and control as an interactive process, in contrast to earlier conceptualizations of trust and control as two relatively static and isolated concepts. While the static perspective...

  10. Quality of life and trust among young people with narcolepsy and their families, after the Pandemrix® vaccination: protocol for a case-control study.

    Science.gov (United States)

    Blomberg, Karin; Carlsson, Agneta Anderzén; Hagberg, Lars; Jonsson, Östen; Leissner, Lena; Eriksson, Mats H

    2017-08-23

    The extensive vaccination programme against swine flu resulted in an increased incidence of narcolepsy among children and adolescents. There is a need to explore if these young persons' experiences have affected their trust in healthcare, their willingness to participate in future prevention programmes, and their contacts with the healthcare system. The overall aim is to identify factors important for the life-situation of children and adolescents with narcolepsy and their families, and factors that correlate with trust in healthcare. Data will be collected via questionnaires from all available children with narcolepsy following the vaccination and their families, as well as a control group of children with diabetes and their families. Longitudinal descriptive interviews will also be conducted with a selection of 20-25 children and their families. Techniques from media research will be used for Internet-based data collection and analysis of information relating to narcolepsy from social media. This project will use the situation of young persons with narcolepsy after the swine flu vaccination as a case to build a model that can be used in situations where trust in healthcare is essential. This model will be based on findings from the included studies on how trust is influenced by support, quality of life, burden of disease, impact on family, and use of social media. The model developed in this project will be beneficial in future situations where trust in healthcare is essential, such as new pandemic outbreaks but also for "everyday" adherence to health advice.

  12. IT Governance in SMEs: Trust or Control?

    Science.gov (United States)

    Devos, Jan; van Landeghem, Hendrik; Deschoolmeester, Dirk

    It is believed by many scholars that a small and medium-sized enterprise (SME) cannot be seen through the lens of a large firm. Theories which explain IT governance in large organizations and methodologies used by practitioners can therefore not be extrapolated to SMEs, which have a completely different economic, cultural and managerial environment. SMEs suffer from resource poverty, have less IS experience and need more external support. SMEs largely contribute to the failure of many IS projects. We define an outsourced information system failure (OISF) as a failure of IT governance in an SME environment and propose a structure for stating propositions derived from both agency theory and theory of trust. The theoretical question addressed in this paper is: how and why do OISFs occur in SMEs? We have chosen a qualitative and positivistic IS case study research strategy based on multiple cases. Eight cases of IS projects were selected. We found that trust is more important than control issues like output-based contracts and structured controls for eliminating opportunistic behaviour in SMEs. We conclude that the world of SMEs is significantly different from that of large companies. This necessitates extra care to be taken on the part of researchers and practitioners when designing artefacts for SMEs.

Cross sectional study involving in depth interviews and documentary analysis; case study to compare savings in management costs between case trusts and control trusts. Nine trusts (cross sectional study) and four trusts (case study) in London. 96 interviews with trust board members, other senior managers, clinicians, service managers, and representatives of health authorities, regional office, community health councils, local authorities, other trusts in the area, and primary care groups and trusts. Stated and unstated drivers, and impact of merger on delivery and development of services, management structures, and staff recruitment, retention, and morale. Effects of difference in trust size before and after the merger. Savings in management costs two years after merger. Some important drivers for merger are not publicly stated. Mergers had a negative effect on delivery of services because of a loss of managerial focus on services. Planned developments in services were delayed by at least 18 months. Trusts' larger sizes after mergers had unintended negative consequences, as well as predicted advantages. The tendency for one trust's management team to dominate over the other resulted in tension. No improvement in recruitment or retention of clinical and managerial staff was reported. Perceived differences in organisational culture were an important barrier to bringing together two or more organisations. Two years after merger, merged trusts had not achieved the objective of saving pound 500 000 a year in management costs. Important unintended consequences need to be accounted for when mergers are planned. Mergers can cause considerable disruptions to services, and require greater management support than previously acknowledged.

We will do this by critically discussing a series of academic studies...... and not as an important sense, a source to pleasure, or a central way of sensually understanding and approaching the world. In other words, taste literacy becomes a tool to push children towards ‘hegemonic nutrition’.

Through this theoretical framework we develop our critique of the existing literature in the aim of proposing alternative taste pedagogy. This pedagogy is based on trust rather than controlling....

  20. Trust via disasters: the case of Chile's 2010 earthquake.

    Science.gov (United States)

    Dussaillant, Francisca; Guzmán, Eugenio

    2014-10-01

    Chile has a long-standing history of natural disasters and, in particular, earthquakes. The latest big earthquake hit Chile on 27 February 2010 with a magnitude of 8.8 on the Richter scale. As an event that had a profound impact on significant portions of the population, the earthquake could theoretically have served to build trust by promoting new trust networks through the enhancement of distant family ties and the interaction between affected neighbours. This study offers an empirical analysis of this theory in the Chilean case. It finds that if initial social capital is very low (thus allowing for post-disaster looting and violence), then the impact of the trust-increasing effect is smaller. It also shows that the effect of the disaster was not transitory, but that it persisted and actually increased over time. © 2014 The Author(s). Disasters © Overseas Development Institute, 2014.

  4. Medical bribery and the ethics of trust: the Romanian case.

    2015-02-01

    Medical bribery seems to be a global problem from Eastern Europe and the Balkans to China, a diffuse phenomenon, starting with morally acceptable gratitude and ending with institutional bribery. I focus my attention on Romania and analyze similar cases in Eastern European and postcommunist countries. Medical bribery can be regarded as a particular form of human transaction, a kind of primitive contract that occurs when people do not trust institutions or other forms of social contract that are meant to guarantee their rights and protect their interests. Concluding with strategies to fight medical bribery, I will underline better public policies for financing health and social care, and an ethic of trust that may help to restore trustworthiness of institutions and to rebuild interpersonal trust. This should be complemented by an educational program dedicated to understanding the negative consequences and mechanisms of corruption and the importance of ethical behavior. © The Author 2014.

  5. Experiences of baby-led weaning: trust, control and renegotiation.

    2015-10-01

    Baby-led weaning (BLW) is an approach to introducing solid foods that relies on the presence of self-feeding skills and is increasing in popularity in the UK and New Zealand. This study aimed to investigate the reported experiences and feelings of mothers using a BLW approach in order to better understand the experiences of the mother and infant, the benefits and challenges of the approach, and the beliefs that underpin these experiences. Fifteen UK mothers were interviewed over the course of a series of five emails using a semi-structured approach. The email transcripts were anonymised and analysed using thematic analysis. There were four main themes identified from the analysis: (1) trusting the child; (2) parental control and responsibility; (3) precious milk; and (4) renegotiating BLW. The themes identified reflect a range of ideals and pressures that this group of mothers tried to negotiate in order to provide their infants with a positive and healthy introduction to solid foods. One of the key issues of potential concern is the timing at which some of the children ingested complementary foods. Although complementary foods were made available to the infants at 6 months of age, in many cases they were not ingested until much later. These findings have potentially important implications for mother's decision-making, health professional policy and practice, and future research. © 2014 John Wiley & Sons Ltd.

    Full Text Available Many education organizations have adopted for security the enterprise best practices for implementation on their campuses, while others focus on ISO Standard (or/and the National Institution of Standards and Technology.All these adoptions are dependent on IT personal and their experiences or knowledge of the standard. On top of this is the size of the education organizations. The larger the population in an education organization, the more the problem of information and security become very clear. Thus, they have been obliged to comply with information security issues and adopt the national or international standard. The case is quite different when the population size of the education organization is smaller. In such education organizations, they use social security numbers as student ID, and issue administrative rights to faculty and lab managers – or they are not aware of the Family Educational Rights and Privacy Act (FERPA – and release some personal information.The problem of education organization security is widely open and depends on the IT staff and their information security knowledge in addition to the education culture (education, scholarships and services has very special characteristics other than an enterprise or comparative organizationThis paper is part of a research to develop an “Education Organization Baseline Control Protection and Trusted Level Security.” The research has three parts: Adopting (standards, Testing and Modifying (if needed.

  8. A generic solution for unwanted traffic control through trust management

    Yan, Zheng; Kantola, Raimo; Shen, Yue

    2014-01-01

    The Internet has dramatically changed our daily life. But it is also bogged down by unwanted traffic, which is malicious, harmful or unexpected for its receivers. In order to control the unwanted traffic over the Internet, especially the mobile Internet, in this paper, we propose a generic unwanted traffic control (UTC) solution through trust management. It can control unwanted traffic from its source to destinations in a personalized manner according to trust evaluation at a Global Trust Operator, traffic and behavior analysis at hosts and traffic observation in the Internet. Thus, it can conduct UTC by integrating distributed and centralized functions and supporting both defensive and offensive approaches. Simulation based evaluation shows that the solution is effective with regard to accuracy and efficiency for botnet intrusion and DDoS intrusion via reflectors. It is also robust against a number of malicious system attacks, such as hide evidence attack, bad mouthing attack, on-off attack, malicious attack by an Internet Service Provider and combinations of the above, playing in conjunction with traffic intrusions. Meanwhile, the solution can provide a personalized UTC based on unwanted traffic detection behaviors.

  9. Trusting outgroup, but not ingroup members, requires control: neural and behavioral evidence

    Science.gov (United States)

    Ambady, Nalini; Zaki, Jamil

    2017-01-01

    Abstract Trust and cooperation often break down across group boundaries, contributing to pernicious consequences, from polarized political structures to intractable conflict. As such, addressing such conflicts require first understanding why trust is reduced in intergroup settings. Here, we clarify the structure of intergroup trust using neuroscientific and behavioral methods. We found that trusting ingroup members produced activity in brain areas associated with reward, whereas trusting outgroup members produced activity in areas associated with top-down control. Behaviorally, time pressure—which reduces people’s ability to exert control—reduced individuals’ trust in outgroup, but not ingroup members. These data suggest that the exertion of control can help recover trust in intergroup settings, offering potential avenues for reducing intergroup failures in trust and the consequences of these failures.

    2016-03-01

    An experiment was performed in a driving simulator to investigate the impacts of practice, trust, and interaction on manual control recovery (MCR) when employing fully automated driving (FAD). To increase the use of partially or highly automated driving efficiency and to improve safety, some studies have addressed trust in driving automation and training, but few studies have focused on FAD. FAD is an autonomous system that has full control of a vehicle without any need for intervention by the driver. A total of 69 drivers with a valid license practiced with FAD. They were distributed evenly across two conditions: simple practice and elaborate practice. When examining emergency MCR, a correlation was found between trust and reaction time in the simple practice group (i.e., higher trust meant a longer reaction time), but not in the elaborate practice group. This result indicated that to mitigate the negative impact of overtrust on reaction time, more appropriate practice may be needed. Drivers should be trained in how the automated device works so as to improve MCR performance in case of an emergency. The practice format used in this study could be used for the first interaction with an FAD car when acquiring such a vehicle. © 2015, Human Factors and Ergonomics Society.

    To investigate the association between political trust in the Riksdag and lack of belief in the possibility to influence one's own health (external locus of control), taking horizontal trust into account. The 2008 public health survey in Skåne is a cross-sectional postal questionnaire study with a 55% participation rate. A random sample of 28,198 persons aged 18-80 years participated. Logistic regression models were used to investigate the associations between political trust in the Riksdag (an aspect of vertical trust) and lack of belief in the possibility to influence one's own health (external locus of control). The multiple regression analyses included age, country of birth, education, and horizontal trust in other people. A 33.7% of all men and 31.8% of all women lack internal locus of control. Low (external) health locus of control is more common in higher age groups, among people born outside Sweden, with lower education, low horizontal trust, low political trust, and no opinion concerning political trust. Respondents with not particularly strong political trust, no political trust at all and no opinion have significantly higher odds ratios of external locus of control throughout the multiple regression analyses. Low political trust in the Riksdag seems to be independently associated with external health locus of control.

    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.

    Cancer patients need to trust their oncologist. How the oncologist communicates probably contributes to patients' trust. Yet, patient characteristics such as their attachment style and health locus of control may influence how such communication is perceived. We examined how these personality characteristics influence trust as well as moderate the relation between oncologist communication and trust. Eight videotaped scenarios of an oncologic consultation were created. Oncologist communication was systematically varied regarding their expressed competence, honesty and caring. Cancer patients (n = 345) were randomly assigned to view the videos and report their trust in the observed oncologist. Patients' self-reported attachment style, health locus of control and trust in their own oncologist were assessed. Patients with a stronger external health locus of control trusted the observed oncologist more (p communication of caring and honesty on trust: avoidant attachment significantly diminished the effect (p style influences how oncologist communication influences trust, underscoring the importance of oncologists tailoring their communication to individual patients. We confirmed observational findings that patients convinced that others control their health trust their oncologist more than others. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available The banking sector has developed and extended the use of its services in the past decade. In fact, nowadays mobile banking (M-banking is the most developing service offered by a bank. In order to encourage customers to use m-banking services, it is extremely important to get clients to trust the M-banking services provided by the bank. This article discusses private clients’ trust in mobile banking in Latvia. Hence, the goal of the research is to identify the key factors driving individual customer’s confidence in mobile banking. In order to determine the weight of each factor, expert evaluation method based on analytic hierarchy process (AHP was used. The results showed that the most vital factor affecting private clients’ trust in mobile banking is customer characteristics, especially customers’ computer literacy. However, after summarizing all the subfactors, it became clear that the most powerful in the trust-building process is convenience/practicality of using a mobile application. However, there is a limitation – the survey was conducted by interviewing experts, which means that the results may differ from the responses of the clients themselves.

  16. Nuclear decommissioning trusts: A case for convertible bonds

    International Nuclear Information System (INIS)

    Nichols, R.W.

    1992-01-01

    Asset-liability management is studied with special emphasis on application of the author's findings to the management of nuclear decommissioning trusts (NDTs). The trust themselves are investment vehicles established to accumulate and build funds to be used to defray future decommissioning costs. Decommissioning, in turn, is the process of dismantling the shell of a nuclear reactor and the surrounding concrete structures, followed by disposal of the radioactive material, the objective being to return the site to a greenfield state i.e. the site is freed up for unrestricted use. Unfortunately, the assets of NDTs are not so easily managed. The liability that the trusts have been established to fund is a highly uncertain moving target for which little historical data is available. This study first develops a framework for selecting portfolios when the investment objective is to invest against a future liability. The challenge then is to build an investment strategy around an uncertain liability, in the presence of taxes and miscellaneous portfolio constraints. The study then explores the viability of convertible bonds for liability-driven investment strategies because of the hybrid debt/equity nature of these instruments

    Full Text Available The Finnish state administration has recently undergone a wave of reforms towards decentralized decision-making and increased flexibility in organizing work. Traditional bureaucracy, however, has its virtues. Based on a survey and qualitative interview material, the results presented in this paper indicate that many characteristics of bureaucracy, such as well-defined work roles and hierarchical control, facilitate trust among employees. In contrast, the current post-bureaucratic model of organizing work may increase insecurity and decrease trust.

    2012-11-01

    Full Text Available Abstract Background In 1999, South Africa became the first African country to approve commercial production of subsistence genetically modified (GM maize. The introduction of GM crop technology is often met with skepticism by stakeholders including farmers. The involvement of the private sector in this process can further breed mistrust or misperceptions. To examine these issues more closely, the objective of this case study was to understand the role of trust in the public-private partnership (PPP arrangement involved in the development of Bacillus thuringiensis (Bt maize in South Africa. Methods We conducted semi-structured, face-to-face interviews to obtain stakeholders’ understanding of trust in general as well as in the context of agricultural biotechnology (agbiotech PPPs. A thematic analysis of the interview transcripts, documents, reports and research articles was conducted to generate insights into the challenges to, and practices for, building trust among the partners and with the public. Results The findings of this study are organized into four main lessons on trust building. First, as the end users of GM technology, farmers must be engaged from the start of the project through field demonstrations and educational activities. Second, an effective technology (i.e., the seed is key to the success of an agbiotech PPP. Third, open communication and full disclosure between private sector companies and government regulatory bodies will build trust and facilitate the regulatory processes. Fourth, enforcing good agronomic practices, including appropriate management of the refuge areas, will serve the interests of both the farmers and the seed companies. Conclusions Trust has proven to be a critical factor determining the success of the Bt maize project in South Africa. Distrust of the private sector and of GM technology were cited as major barriers to building trust. The trust-building practices described in this case study have often

    Full Text Available The main aim of this study was to develop advertising strategies in order to increase consumer trust. Four advertising elements: celebrity endorsement, branding, product attribute, and third party certification were investigated. Data were collected to answer two research questions: (1 To investigate the advertising strategies of skin care products leading to consumer trust, (2 To know the effects of advertising strategies in skin care products on consumer trust. A 5-point Likert scale survey was distributed to the female population in Taipei area. Via online and personal approaches, 266 questionnaires were returned. Targeting on 18-30 years old female skin care product users who stay in Taipei area more than six months, 240 qualified questionnaires were analyzed. The four independent variables are found having a significant relationship with trust in skin care advertising, in which branding has the greatest influence on increasing consumer trust. The control variable which is financial status is not found having statistically significant effect on consumer trust. To conclude, this study is dedicated to the communities in order to optimize their marketing strategies.

    2009-03-01

    Trust is widely recognised is a core feature of partnership relationships and one that facilitates joint work. It is an issue that must be addressed if partnerships are to enhance service system integration. In recent literature trust has been linked to concepts of risk and control. In this study of trust within a Primary Care Partnership (PCP) in Australia the experiences of risk and uncertainty, and control, of participants in different structural positions, were explored in detail. The data used in this paper was qualitative, derived from 63 interviews with managers and service providers participating in committees of the PCP. This paper reports on the differences in the experience of risk and uncertainty, trust and control, of managers and service providers working as boundary spanners through the committees of a PCP. For managers there were significant risks and uncertainties, and trust and control were important. For service providers there were few risks and uncertainties, and trust and control were of much less importance. Some policy implications of the differences in perspective are discussed, as are important areas for further research.

    Achieving excellence is a current preoccupation in U.K. public health organisations. This article aims to use a case study to explain how a mental health trust delivers excellent performance using a balanced scorecard (BSC) management approach. Reports a project to implement a BSC approach in the South West Yorkshire Mental Health NHS Trust to achieve its "excellence" objectives. The authors were participants in the project. The design of the pilot project was informed theoretically by the work of Kaplan and Norton and practically by in-house discussions on a strategy to achieve excellence. Explains the process of building a BSC strategy step-by-step. Discusses how the vision and strategies of a mental health trust can be translated into tangible measures, which are the basis for actions that are driven strategically. There are many possibilities for a BSC management approach and this case study is specific to mental health trusts in the UK, although it is believed that the case has a universally applicable modus operandi. This article will help healthcare managers to evaluate the benefits of a BSC management approach. This article explains how actions can be structured in connection with a BSC management approach.

    To investigate the external and internal governance of NHS foundation trusts (FTs), which have increased autonomy, and local members and governors unlike other NHS trusts. In depth, three-year case studies of four FTs; and analysis of national quantitative data on all FT hospitals and NHS Trust hospitals to give national context. Data included 111 interviews with managers, clinicians, governors and members, and local purchasers; observation of meetings; and analysis of FTs' documents. The four case study FTs were similar to other FTs. They had used their increased autonomy to develop more business-like practices. The FT regulator, Monitor, intervened only when there were reported problems in FT performance. National targets applying to the NHS also had a large effect on FT behaviour. FTs saw themselves as part of the local health economy and tried to maintain good relationships with local organisations. Relationships between governors and the FTs' executives were still developing, and not all governors felt able to hold their FT to account. The skills and experience of staff members and governors were under-used in the new governance structures. It is easier to increase autonomy for public hospitals than to increase local accountability. Hospital managers are likely to be interested in making decisions with less central government control, whilst mechanisms for local accountability are notoriously difficult to design and operate. Further consideration of internal governance of FTs is needed. In a deteriorating financial climate, FTs should be better placed to make savings, due to their more business-like practices.

  5. Science, safety, and trust: the case of transgenic food.

    Science.gov (United States)

    Martinelli, Lucia; Karbarz, Małgorzata; Siipi, Helena

    2013-02-01

    Genetically modified (GM) food is discussed as an example of the controversial relation between the intrinsic uncertainty of the scientific approach and the demand of citizen-consumers to use products of science innovation that are known to be safe. On the whole, peer-reviewed studies on GM food safety do not note significant health risks, with a few exceptions, like the most renowned "Pusztai affair" and the recent "Seralini case." These latter studies have been disregarded by the scientific community, based on incorrect experimental designs and statistic analysis. Such contradictory results show the complexity of risk evaluation, and raise concerns in the citizen-consumers against the GM food. A thoughtful consideration by scientific community and decision makers of the moral values that are present in risk evaluation and risk management should be the most trustable answer to citizen-consumers to their claim for clear and definitive answers concerning safety/un-safety of GM food.

    To understand organisational technology adoption (initiation, adoption decision, implementation) by looking at the different types of innovation knowledge used during this process. Qualitative, multisite, comparative case study design. One primary care and 11 acute care organisations (trusts) across all health regions in England in the context of infection prevention and control. PARTICIPANTS AND DATA ANALYSIS: 121 semistructured individual and group interviews with 109 informants, involving clinical and non-clinical staff from all organisational levels and various professional groups. Documentary evidence and field notes were also used. 38 technology adoption processes were analysed using an integrated approach combining inductive and deductive reasoning. Those involved in the process variably accessed three types of innovation knowledge: 'awareness' (information that an innovation exists), 'principles' (information about an innovation's functioning principles) and 'how-to' (information required to use an innovation properly at individual and organisational levels). Centralised (national, government-led) and local sources were used to obtain this knowledge. Localised professional networks were preferred sources for all three types of knowledge. Professional backgrounds influenced an asymmetric attention to different types of innovation knowledge. When less attention was given to 'how-to' compared with 'principles' knowledge at the early stages of the process, this contributed to 12 cases of incomplete implementation or discontinuance after initial adoption. Potential adopters and change agents often overlooked or undervalued 'how-to' knowledge. Balancing 'principles' and 'how-to' knowledge early in the innovation process enhanced successful technology adoption and implementation by considering efficacy as well as strategic, structural and cultural fit with the organisation's context. This learning is critical given the policy emphasis for health organisations to

    Interconnections between process control networks and enterprise networks expose instrumentation and control systems and the critical infrastructure components they operate to a variety of cyber attacks. Several architectural standards and security best practices have been proposed for industrial control systems. However, they are based on older architectures and do not leverage the latest hardware and software technologies. This paper describes new technologies that can be applied to the design of next generation security architectures for industrial control systems. The technologies are discussed along with their security benefits and design trade-offs.

    2011-10-01

    Objectives: This paper explored the relationship between trust and information sharing in South African automotive supply chains, and establishes the importance of nurturing a cyclical relationship between these two factors. In addition, the role of information technology (IT in supporting this relationship was considered. By improving both trust and information sharing, the performance and competitiveness of the supply chain can be improved. Method: An examination of the effects of a lack of trust in a supply chain relationship, and the consequential lack of information flow, was conducted by means of a case study of an Eastern Cape-based automotive supplier. A case study research method was followed for this study, which made use of multiple data collection methods, including document survey and participant observations. The case selected is an East London based subsidiary of a larger multinational automotive component supplier to both local and international automotive original equipment manufacturers. Results: The findings led to the conclusion that the way forward for competitive supply chains is to build trust in the supply chain in order to improve information flow, and vice versa. Information technology can be used to nurture this cyclical relationship between trust and information sharing. Conclusion: It is proposed that simultaneously improving information flow and trust in an interorganisational relationship leads to improved supply chain performance and competitiveness.

    Full Text Available Crowdsourcing has been widely accepted across a broad range of application areas. In crowdsourcing environments, the possibility of performing human computation is characterized with risks due to the openness of their web-based platforms where each crowd worker joins and participates in the process at any time, causing serious effect on the quality of its computation. In this paper, a combination of Trust-Based Access Control (TBAC strategy and fuzzy-expert systems was used to enhance the quality of human computation in crowdsourcing environment. A TBAC-fuzzy algorithm was developed and implemented using MATLAB 7.6.0 to compute trust value (Tvalue, priority value as evaluated by fuzzy inference system (FIS and finally generate access decision to each crowd-worker. In conclusion, the use of TBAC is feasible in improving quality of human computation in crowdsourcing environments.

    2007-08-01

    Few scholars doubt the importance of trust in explaining variation in public perception of technological risk. Relatively little, however, is known about the particular types of judgments that people use in granting or withholding trust. This article presents findings from an empirical study that explores several dimensions of trust relevant for citizens' judgments of scientists involved in the development of GM food. The relationship between particular dimensions of trust and perceptions of GM food risk is also explored, using structural equation modeling. Results suggest that trust judgments based on the perception of shared values are most important in relation to GM food risk, but that judgments about scientists' technical competence are also important.

    Communities neighboring federally protected natural areas regularly weigh the costs and benefits of the administering agency’s programs and policies. While most agencies integrate public opinion into decision making, efforts to standardize and formalize public involvement have left many local communities feeling marginalized, spurring acrimony and opposition. A significant body of research has examined barriers to effective public participation as well as strategies for relationship building in planning processes; many of which point to trust as a key factor. Trust is especially tenuous in local communities. This paper explores perceptions of trust, expectations for management, as well as constraints to building trust. In-depth interviews were conducted with 21 community members and USDA Forest Service personnel at the Midewin National Tallgrass Prairie in northeastern Illinois. The interviews revealed that trust is perceived as important to effective management. Distinct expectations for management outcomes and processes emerged, including the values, knowledge, and capacity demonstrated in management decisions and actions and opportunities provided for communication, collaboration, and cooperation within the agency-community relationship. The case study identified several constraints to building trust, including competing values, knowledge gaps, limited community engagement, and staff turnover.

Functioning analysis of these systems with decentralized control is carried out. The type of the so-called soft attacks using interception of messages, misinformation formation and transmission to group of robots which are also realizing other actions without identified signs of invasion of robots-saboteurs. Analysis of existing information security models of the system based on the trust level computation, calculated in the process of agents’ interaction is carried out. Information security model is offered in which robots-agents produce the trust levels to each other on the basis of situation analysis emerging on a certain step of iterative algorithm with usage of onboard sensor devices. On the basis of calculated trust levels, recognition of “saboteur” objects in the group of legitimate robots-agents is done. For measure of likeness (adjacency increase for objects from the same category (“saboteur” or “legitimate agent”, calculation algorithm for agents reputation is offered as a measure of public opinion about qualities of this or that agent-subject. Implementation alternatives of the algorithms for detection of saboteurs on the example of the basic algorithm for distribution of purposes in the group of robots are considered.

  19. Social norms, trust and control of power theft in Uganda: Does bulk metering work for MSEs?

    Never, Babette

    2015-01-01

    Power theft is still rampant in many developing countries. Governments and utility providers tend to favor technical solutions, neglecting the socio-economic dimension. This article analyzes the interaction between the socio-economic factors trust, informal social norms, awareness and electricity pricing effect and technical control measures in Uganda. After reforming its power sector, Uganda introduced two technical innovations: bulk metering for micro and small enterprises (MSE) and prepaid metering for households. The bulk metering system imposes a strong form of social control among MSEs. Drawing on semi-structured interviews with 29 MSEs and 16 experts in Uganda, this article shows how well bulk metering works in practice. It finds that trust is key in the relations between electricity user and utility provider, between citizens and government overseeing the energy sector as well as within bulk metering groups of MSEs. The electricity price impacts MSEs' ability to pay and to some extent also their willingness to pay. Finally, power theft used to be accepted as an informal social norm. Change is happening, but is currently undermined by corruption and patronage networks in the energy sector and the political system, impacting people's attitude to compliance – regardless of the privatization of the electricity sector. -- Highlights: •Socio-economic factors impact the control of power theft. •Bulk metering works well for those MSE groups with high trust and information. •Sub-meters need to be available and energy recordings possible. •Prepaid metering more suitable for areas with a lot of social tension. •Long-term norm change and social acceptance depends on perceptions of political economy

  20. Analogical Trust Reasoning

    Science.gov (United States)

    Tavakolifard, Mozhgan; Herrmann, Peter; Öztürk, Pinar

    Trust is situation-specific and the trust judgment problem with which the truster is confronted might be, in some ways, similar but not identical to some problems the truster has previously encountered. The truster then may draw information from these past experiences useful for the current situation. We present a knowledge-intensive and model-based case-based reasoning framework that supports the truster to infer such information. The suggested method augments the typically sparse trust information by inferring the missing information from other situational conditions, and can better support situation-aware trust management. Our framework can be coupled with existing trust management models to make them situation-aware. It uses the underlying model of trust management to transfer trust information between situations. We validate the proposed framework for Subjective Logic trust management model and evaluate it by conducting experiments on a large real dataset.

    Full Text Available Abstract Background Agricultural biotechnology public-private partnerships (PPPs have been recognized as having great potential in improving agricultural productivity and increasing food production in sub-Saharan Africa. However, there is much public skepticism about the use of GM (genetically modified crops and suspicion about private sector involvement in agbiotech projects. This case study sought to understand the role of trust in the Bacillus thuringiensis (Bt cotton in Burkina Faso project by exploring practices and challenges associated with trust-building, and determining what makes these practices effective from the perspective of multiple stakeholders. Methods We conducted semi-structured, face-to-face interviews to obtain stakeholders’ understanding of trust in general as well as in the context of agbiotech PPPs. Relevant documents and articles were analyzed to generate descriptions of how trust was operationalized in this evolving agbiotech PPP. Data was analyzed based on emergent themes to create a comprehensive narrative on how trust is understood and built among the partners and with the community. Results We derived four key lessons from our findings. First, strong collaboration between research, industry and farmers greatly contributes to both the success of, and fostering of trust in, the partnership. Second, this case study also revealed the important, though often unrecognized, role of researchers as players in the communication strategy of the project. Third, effective and comprehensive communication takes into account issues such as illiteracy and diversity. Fourth, follow-up at the field level and the need for a multifaceted communications strategy is important for helping push the project forward. Conclusions Burkina Faso’s well-established and effective cotton selling system laid the foundation for the implementation of the Bt cotton project – particularly, the strong dialogue and the receptivity to collaboration

    2012-03-01

    Full Text Available Abstract Background Ongoing care for chronic conditions such as diabetes is best provided by a range of health professionals working together. There are challenges in achieving this where collaboration crosses organisational and sector boundaries. The aim of this article is to explore the influence of power dynamics and trust on collaboration between health professionals involved in the management of diabetes and their impact on patient experiences. Methods A qualitative case study conducted in a rural city in Australia. Forty five health service providers from nineteen organisations (including fee-for-service practices and block funded public sector services and eight patients from two services were purposively recruited. Data was collected through semi-structured interviews that were audio-taped and transcribed. A thematic analysis approach was used using a two-level coding scheme and cross-case comparisons. Results Three themes emerged in relation to power dynamics between health professionals: their use of power to protect their autonomy, power dynamics between private and public sector providers, and reducing their dependency on other health professionals to maintain their power. Despite the intention of government policies to support more shared decision-making, there is little evidence that this is happening. The major trust themes related to role perceptions, demonstrated competence, and the importance of good communication for the development of trust over time. The interaction between trust and role perceptions went beyond understanding each other's roles and professional identity. The level of trust related to the acceptance of each other's roles. The delivery of primary and community-based health services that crosses organisational boundaries adds a layer of complexity to interprofessional relationships. The roles of and role boundaries between and within professional groups and services are changing. The uncertainty and

    Trust is important for the perception of many types of risk, including those relating to genetically modified (GM) food. Who the public trusts in any given circumstance, however, is not well understood. In this study of public trust regarding GM food, an exploratory factor analysis with Promax rotation reveals public classification of three common institutional types-evaluators, watchdogs, and merchants. The structure of relationships among these stakeholders can act to enable or constrain public support for this new technology. Evaluators-scientists, universities, and medical professionals-are the most trusted. Watchdogs-consumer advocacy organizations, environmental organizations, and media sources-are moderately trusted. Merchants-grocers and grocery stores, industry, and farmers-are least trusted. While the federal government is seen as closest to being an evaluator, it is not highly correlated with any of the factors. The lack of trust in the organizations with the greatest resources and responsibilities for ensuring the safety of GM food should be seen as an important obstacle to the adoption of the technology.

    It has been found that a low level of trust among members of a construction project team leads to poor performance in China. Many researchers have described the challenges, consequently advocating partnering as an attractive approach for more valuable cooperation. Because substantial investments have been poured into construction projects since the year 2000, trust research will improve the performance of construction projects and will be meaningful to the Chinese construction industry. The purpose of this paper is to investigate the attributes affecting owners' trust of contractors, to understand the potential properties of these factors, and to rank the factors in order of importance. Twenty-four attributes are identified from a literature review. Supported by qualitative reviews, a questionnaire is conducted to obtain relevant data, and 168 valid responses are obtained for data analysis. Principal component analysis (PCA) is employed to find the factor structure of the identified trust attributes. By the method of PCA, the attributes are extracted into eight factors, including interaction history, information sharing and communication, contract and institution, relation-specific investment, reputation, integrity, competence, and opportunistic behaviour. The value and originality of this paper are embodied in using PCA to understand the various attribute groupings and to illuminate trust impact factors in the Chinese context. When they understand the critical factors affecting trust better, owners and contractors can devise more appropriate strategies to improve performance.

  14. Factors Influencing Private Customers′ Trust in Internet Banking: Case of Latvia

    Full Text Available Banking sector has developed and extended the usage of online services in the past decade. In fact, nowadays, Internet-based banking services dominate over other historically provided alternatives. This article discusses private clients′ trust in Internet banking in Latvia. The model of trust in Internet banking was developed based on four factors, distinguished in the scientific literature. They are provided information, bank’s characteristics, ebanking system and website of a bank. Hence, the goal of the research is to measure the impact of distinguished factors on trust in Internet banking. In order to determine how these attributes affect private customers′ trust, correlation and regression analysis were applied. The results showed that the most vital factor affecting private clients’ trust in Internet banking is e-banking system. What is more, it was found that provided information is a statistically insignificant factor and, hence, it was removed from the model. Respondents, being private customers, limit the breadth of study, thus the results do not reflect companies’ trust in Internet banking.

    Trust underpins the Chinese social system, and yet it is lacking from a Chinese food system that is riddled with safety disasters and disgruntled consumers. Government and industry play a major role in rehabilitating consumer trust in China. To this end, food safety and quality laws have been constructed to foster this process; however, safety scandals continue even in the face of stricter regulations and increased enforcement. A potential toll to abate food-safety problems and to build trust is the implementation of Corporate Social Responsibility ("CSR"). Mandates by the government promote CSR in enterprise activity, including Article 3 of the 2009 China Food Safety Law. Officials have also recently touted the need for "moral education" of operators in the food industry. Regardless of government activity or whether CSR is employed by food enterprises, it is imperative that the food industry recognizes how critical it is to establish trust with Chinese consumers, who increasingly expect safe, quality food. The case study with pistachios highlights this evolving consumer expectation and the principles of social responsibility in the framework of the relationship between government and industry and consumers, while demonstrating the benefits of doing the right thing for food companies doing business in China.

    Full Text Available Social computing and online communities are changing the fundamental way people share information and communicate with each other. Social computing focuses on how users may have more autonomy to express their ideas and participate in social exchanges in various ways, one of which may be peer-to-peer (P2P file sharing. Given the greater risk of opportunistic behavior by malicious or criminal communities in P2P networks, it is crucial to understand the factors that affect individual’s use of P2P file sharing software. In this paper, we develop and empirically test a research model that includes trust beliefs and perceived risks as two major antecedent beliefs to the usage intention. Six trust antecedents are assessed including knowledge-based trust, cognitive trust, and both organizational and peer-network factors of institutional trust. Our preliminary results show general support for the model and offer some important implications for software vendors in P2P sharing industry and regulatory bodies.

  18. The Conflicting Link between Institutionalized Participation and Trust: the Case of Buenos Aires

    Full Text Available This paper explores the relationship between trust and institutionalized participation. Trust is defined as a subjective expectation about the world that can be disappointed. It is assumed to be related to time, authority, and knowledge. Further, it allows for a retrospective evaluation. In light of this definition, we first analyze the links between participation and trust in established relations between public authorities and citizens in liberal democracies. Next, we examine how institutionalized participation is currently conceived as an efficient tool for overcoming citizens' mistrust of political authorities and institutions. Finally, we argue that participation does not assuage that mistrust, but transforms the nature of the relationship between authorities and citizens, giving rise to what might be characterized as a "government of mistrust".

  19. Reputation, relationships, risk communication, and the role of trust in the prevention and control of communicable disease: a review.

    Cairns, Georgina; de Andrade, Marisa; MacDonald, Laura

    2013-01-01

    Population-level compliance with health protective behavioral advice to prevent and control communicable disease is essential to optimal effectiveness. Multiple factors affect perceptions of trustworthiness, and trust in advice providers is a significant predeterminant of compliance. While competency in assessment and management of communicable disease risks is critical, communications competency may be equally important. Organizational reputation, quality of stakeholder relationships and risk information provision strategies are trust moderating factors, whose impact is strongly influenced by the content, timing and coordination of communications. This article synthesizes the findings of 2 literature reviews on trust moderating communications and communicable disease prevention and control. We find a substantial evidence base on risk communication, but limited research on other trust building communications. We note that awareness of good practice historically has been limited although interest and the availability of supporting resources is growing. Good practice and policy elements are identified: recognition that crisis and risk communications require different strategies; preemptive dialogue and planning; evidence-based approaches to media relations and messaging; and building credibility for information sources. Priority areas for future research include process and cost-effectiveness evaluation and the development of frameworks that integrate communication and biomedical disease control and prevention functions, conceptually and at scale.

    This article describes how trust among team members and in the technology supporting them was eroded during implementation of an electronic health record (EHR) in an adult outpatient oncology practice at a comprehensive cancer center. Delays in care of a 38-year-old woman with high-risk breast cancer occurred because of ineffective team communication and are illustrated in a case study. The case explores how the patient's trust and mutual trust between team members were disrupted because of inaccurate assumptions about the functionality of the EHR's communication tool, resultant miscommunications between team members and the patient, and the eventual recognition that care was not being effectively coordinated, as it had been previously. Despite a well-established, team-based culture and significant preparation for the EHR implementation, the challenges that occurred point to underlying human and system failures from which other organizations going through a similar process may learn. Through an analysis and evaluation of events that transpired before and during the EHR rollout, suggested interventions for preventing this experience are offered, which include: a thorough crosswalk between old and new communication mechanisms before implementation; understanding and mitigation of gaps in the communication tool's functionality; more robust training for staff, clinicians, and patients; greater consideration given to the pace of change expected of individuals; and development of models of collaboration between EHR users and vendors in developing products that support high-quality, team-based care in the oncology setting. These interventions are transferable to any organizational or system change that threatens mutual trust and effective communication.

    2012-01-01

    The role of trust has been argued to play an increasingly important role in modern, complex, and ambivalent risk societies. Trust within organizational research is anticipated to have a general strategic impact on aspects such as organizational performance, communication and knowledge exchange, and learning from accidents. Trust is also an important aspect related to regulation of risk. Diverse regulatory regimes, their contexts and risks influence regulators use of trust and distrust in regulatory practice. The aim of this paper is to discuss the relationship between risk regulation and trust across diverse risk regulation regimes. By drawing from studies of risk regulation, risk perception, and trust the purpose is to discuss how regulation and trust are linked and used in practice to control risk across system levels in socio-technical systems in high risk industries. This paper provides new knowledge on 1) how functional and dysfunctional trust and distrust are grounded in the empirical realities of high risk industries, 2) how different perspectives on trust and distrust act together and bring new knowledge on how society control risk.

    2016-04-01

    The internet has become an increasingly important way of communicating with consumers about food risk information. However, relatively little is known about how consumers evaluate and come to trust the information they encounter online. Using the example of unpasteurized or raw milk this paper presents two studies exploring the trust factors associated with online information about the risks and benefits of raw milk consumption. In the first study, eye-tracking data was collected from 33 pasteurised milk consumers whilst they viewed six different milk related websites. A descriptive analysis of the eye-tracking data was conducted to explore viewing patterns. Reports revealed the importance of images as a way of capturing initial attention and foregrounding other features and highlighted the significance of introductory text within a homepage. In the second, qualitative study, 41 consumers, some of whom drank raw milk, viewed a selection of milk related websites before participating in either a group discussion or interview. Seventeen of the participants also took part in a follow up telephone interview 2 weeks later. The qualitative data supports the importance of good design whilst noting that balance, authorship agenda, the nature of evidence and personal relevance were also key factors affecting consumers trust judgements. The results of both studies provide support for a staged approach to online trust in which consumers engage in a more rapid, heuristic assessment of a site before moving on to a more in-depth evaluation of the information available. Findings are discussed in relation to the development of trustworthy online food safety resources. Copyright © 2016 Elsevier Ltd. All rights reserved.

  6. Citizenship education, national identity and political trust: The Case of Sweden

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available The challenging effects of globalization upon the nation-state have been a recurrent theme in the social science discourse since the 1990’s. Nationally organized education is also seen as challenged by new demands originating from globalization. In this article it is argued that ‘nation-state’ and ‘national identity’ are highly relevant concepts when discussing a citizenship education that seeks to develop a civic ethos with, potentially, a global reach. It is further argued that the understanding of such an ethos would benefit significantly from incorporating the role of political trust since trust has been identified as a main feature of the social capital that makes democracy work. Three themes are brought together: national identity and identification, the importance for democracy of political trust and the challenges citizenship education face when carried out in a national context but intended to manage issues that go far beyond the reach of the nation-state. The importance of citizenship education is discussed using recent research on the Swedish citizenship education classroom

    Full Text Available The adoption of bioregionalism by institutions that are instrumental in river basin management has significant potential to resolve complex water resource management problems. The Westcountry Rivers Trust (WRT in England provides an example of how localized bioregional institutionalization of adaptive comanagement, consensus decision making, local participation, indigenous technical and social knowledge, and "win-win" outcomes can potentially lead to resilient partnership working. Our analysis of the WRT's effectiveness in confronting nonpoint source water pollution, previously impervious to centralized agency responses, provides scope for lesson-drawing on institutional design, public engagement, and effective operation, although some evident issues remain.

Once the workforce was behind the campaign, TRUST US was taken to the west Cumbrian community, providing quality information through news releases, media advertisements and a specially produced brochure which highlighted the reasons behind TRUST US. This was sent to all MPs, MEPs, councils and Trade Unions throughout the UK and Ireland. The campaign also targeted MPs and MEPs with specific letters setting out the case for THORP. However, the organised opposition' to THORP did not come from the local area, but from the rest of the UK, Ireland and Europe, lead by nuclear free local authorities and green pressure groups, which severely limited the effectiveness of the campaign. It was decided that yet another new approach was needed. On 2 August 1993, proposals for a national tour of the- campaign were presented to the Sellafield Trade Unions. The tour objectives were to take the TRUST US campaign to the rest of the UK, demonstrating that the plant had strong support with two key areas: the workforce and the local community. The overriding tone of the entire tour was to 'trust us' as workers in the nuclear industry, which was backed up by the tour message: W e, the Sellafield workers and the west Cumbrian community have trust in THORP. The new plant is economically and environmentally sound. We have the work; let us get on with that work. The tour would target the media centres of the UK, he Nuclear Free Local Authority (NFLA) areas and Sellafield's suppliers within these areas. A group of five workers plus a member of the clerks committee would make up the tour messengers, each to be given extensive media training. The tour would be given a high profile with a specific logo, designed to ensure that the tour aid its message of 'trust us' was given image prominence. Posters, leaflets and badges would also carry the logo. Given

  11. Rethinking trust.

    Kramer, Roderick M

    2009-06-01

    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.

    2013-11-01

    This project sought to describe the involvement of doctors in leadership roles in the NHS and the organisational structures and management processes in use in NHS trusts. A mixed methods approach was adopted combining a questionnaire survey of English NHS trusts and in-depth case studies of nine organisations who responded to the survey. Respondents identified a number of challenges in the development of medical leadership, and there was often perceived to be an engagement gap between medical leaders and doctors in clinical roles. While some progress has been made in the development of medical leadership in the NHS in England, much remains to be done to complete the journey that started with the Griffiths Report in 1983. We conclude that a greater degree of professionalism needs to be brought to bear in the development of medical leadership. This includes developing career structures to make it easier for doctors to take on leadership roles; providing training, development and support in management and leadership at different stages of doctors' careers; and ensuring that pay and other rewards are commensurate with the responsibilities of medical leaders. The time commitment of medical leaders and the proportion of doctors in leadership roles both need to increase. The paper concludes considering the implications of these findings for other health systems. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Sundstrom, Beth; Szabo, Caitlin; Dempsey, Angela

    2018-01-01

    Postpartum contraception helps reduce unintended pregnancy and space births to improve maternal and child health. This study explored women's perceptions of contraceptive choice during the postpartum period in the context of locus of control and trust in healthcare providers. Researchers conducted six focus groups with 47 women, ages 18-39, receiving postpartum care at an outpatient clinic. Techniques from grounded theory methodology provided an inductive approach to analysis. HyperRESEARCH 3.5.2 qualitative data analysis software facilitated a constant-comparative coding process to identify emergent themes. Participants expressed a preference for relationship-centered care, in which healthcare providers listened, individualized their approach to care through rapport-building, and engaged women in shared decision-making about contraceptive use through open communication, reciprocity, and mutual influence. Conflicting health messages served as barriers to uptake of effective contraception. While participants trusted their healthcare provider's advice, many women prioritized personal experience and autonomy in decisions about contraception. Providers can promote trust and relationship-centered care to optimize contraceptive uptake by listening, exploring patient beliefs and preferences about contraception and birth spacing, and tailoring their advice to individuals. Results suggest that antenatal contraceptive counseling should incorporate information about effectiveness, dispel misconceptions, and engage patients in shared decision-making.

    2017-12-01

    Volunteered Geographic Information (VGI), defined as geographic information contributed voluntarily by amateurs, have grown exponentially nowadays with the aid of ubiquitous GPS-enabled telecommunication technologies. VGI projects, like Wikimapia, OpenStreetMap, Flickr and Safecast have shown remarkable success on leveraging citizen science to increase our knowledge about the geographic world. However, in spite of its growing popularity, VGI is still facing the most challenging problem of ensuring data quality. In this study, we proposed a methodology to filter outliers in Safecast measurements through cross-reference among volunteers. Based on the outliers filtered, a trust index is generated for each volunteer. The results are validated using official radiation measurements surveyed by Department of Energy. The validation shows that removing the outliers filtered by our methodology, Safecast measurements yield a better correlation with official measurements.

  17. Effect of Local Community’s Environmental Perception on Trust in a Mining Company: A Case Study in Mongolia

    Directory of Open Access Journals (Sweden)

    Lavdmaa Dagvadorj

    2018-02-01

    Full Text Available While the mining industry is booming globally, local communities resist mining operations. It is crucial for mining companies to maintain trust within these communities to prevent conflicts. This research investigated local community’s trust in a mining company in Mongolia using a questionnaire survey. We assessed the residents’ perceptions of the company’s effort to maintain environmental protection, as a determinant of trust, in addition to the determinants of motivation and ability. The results showed that the trust level varied within the different respondent groups and the determinants of trust differentially explained the state of trust. The nomadic herders who lived close to the mine site had low trust while being sensitive to the environmental effects. Other herders had neutral trust. Town citizens had high trust, which was mainly related to positive perceptions of motivation. Communicability of the information provided by the company influenced formulation of positive and negative perceptions. Overall, low trust likely leads to conflicts. Therefore, mining companies are advised to conduct surveys with different groups in the local community, especially those sensitive to environmental changes, and take measures to maintain trust.

  18. How did rapid scale-up of HIV services impact on workplace and interpersonal trust in Zambian primary health centres: a case-based health systems analysis.

    Topp, Stephanie M; Chipukuma, Julien M

    2016-01-01

    In sub-Saharan Africa, large amounts of funding continue to be directed towards HIV-specific care and treatment, often with claims of 'health system strengthening' effect. Such claims rarely account for the impact on human relationships and decisions that are core to functional health systems. This research examined how establishment of externally funded HIV services influenced trusting relationships in Zambian health centres. An in-depth, multicase study included four health centres selected for urban, peri-urban and rural characteristics. Case data included healthcare worker (HCW) interviews (60); patient interviews (180); direct observation of facility operations (2 weeks/centre) and key informant interviews (14) which were recorded and transcribed verbatim. Thematic analysis adopted inductive and deductive coding guided by a framework incorporating concepts of workplace trust, patient-provider trust, intrinsic and extrinsic motivation. HIV service scale-up impacted trust in positive and negative ways. Investment in HIV-specific infrastructure, supplies and quality assurance mechanisms strengthened workplace trust, HCW motivation and patient-provider trust in HIV departments in the short-term. In the health centres more broadly and over time, however, non-governmental organisation-led investment and support of HIV departments reinforced HCW's perceptions of the government as uninterested or unable to provide a quality work environment. Exacerbating existing perceptions of systemic workplace inequity and nepotism, uneven distribution of personal and professional opportunities related to HIV service establishment contributed to interdepartmental antagonism and reinforced workplace practices designed to protect individual HCW's interests. Findings illustrate long-term negative effects of the vertical HIV resourcing and support structures which failed to address and sometimes exacerbated HCW (dis)trust with their own government and supervisors.

In an experimental study participants played the trust game while performing one of two different secondary tasks - listening to a disturbing noise or memorizing a sequence of characters - or with no additional task in the control condition. Results show that in both cognitive load conditions participants expressed significantly less trust in the trust game than in case of no cognitive load. Additionally, when cognitive resources were limited, participants' behavior was more impulsive than when their resources were fully available.

  1. Zero Trust Cloud Networks using Transport Access Control and High Availability Optical Bypass Switching

    Full Text Available Cyberinfrastructure is undergoing a radical transformation as traditional enterprise and cloud computing environments hosting dynamic, mobile workloads replace telecommunication data centers. Traditional data center security best practices involving network segmentation are not well suited to these new environments. We discuss a novel network architecture, which enables an explicit zero trust approach, based on a steganographic overlay, which embeds authentication tokens in the TCP packet request, and first-packet authentication. Experimental demonstration of this approach is provided in both an enterprise-class server and cloud computing data center environment.

    2014-01-01

    This paper discusses a case study that examined the influence of cultural, organizational and automation capability upon human trust in, and reliance on, automation. In particular, this paper focuses on the design and application of an extended case study methodology, and on the foundational lessons revealed by it. Experimental test pilots involved in the research and development of the US Air Force's newly developed Automatic Ground Collision Avoidance System served as the context for this examination. An eclectic, multi-pronged approach was designed to conduct this case study, and proved effective in addressing the challenges associated with the case's politically sensitive and military environment. Key results indicate that the system design was in alignment with pilot culture and organizational mission, indicating the potential for appropriate trust development in operational pilots. These include the low-vulnerability/ high risk nature of the pilot profession, automation transparency and suspicion, system reputation, and the setup of and communications among organizations involved in the system development.

  8. Towards a politics of trust.

    Science.gov (United States)

    Gilbert, T

    1998-05-01

    This paper draws upon sociological theory to demonstrate that the manufacture and deployment of trust is an integral part of the function of complex systems such as health care. The discussion begins by identifying the error within the nursing literature which arises from a rather technical conceptualization of trust. This tends to limit the dimensions to trust which is established, and fails to recognize that trust may be subject to competition and conflict. The paper continues by drawing upon the work of two theorists, Niklas Luhmann and Susan P. Shapiro, to demonstrate how trust functions within systems such as health care and the mechanisms through which it is controlled. The title of this paper, 'Towards a politics of trust', identifies that this is merely the first stage in the analysis. Further stages are necessary which analyse the ways in which power is exercised in the conflict for control within discrete elements of the system.

    This article describes the theoretical-conceptual frame of equine-facilitated psychotherapy (EFP) for adolescents at-risk, the unique components of this intervention, and its implementation in an evaluation study. The study was conducted at a residential treatment facility for adolescents at-risk. We examined the outcomes of EFP on self-image, self-control, trust and general life satisfaction. Fourteen resident adolescents comprised the treatment group, and were compared with a matched group of 15 residents who did not receive EFP (control). The treatment comprised a weekly individual EFP session over a period of seven months. The study found a trend of positive change in all four research parameters within the treatment group. Additional indications of the intervention's positive influence were also found and are discussed.

    2011-12-01

    Limited trust, cooperation and communication have been identified as some of the issues that hinder collaboration among business partners. These one also true in the acceptance of e-supply chain integrator among organizations that involve in the same industry. On top of that, the huge number of components in supply chain industry also makes it impossible to include entire supply chain components in the integrator. Hence, this study intends to propose a method for identifying "trusted" collaborators for inclusion into an e-supply chain integrator. For the purpose of constructing and validating the method, the Malaysian construction industry is chosen as the case study due to its size and importance to the economy. This paper puts forward the background of the research, some relevant literatures which lead to trust values elements formulation, data collection from Malaysian Construction Supply Chain and a glimpse of the proposed method for trusted partner selection. Future work is also presented to highlight the next step of this research.

    Full Text Available Background: The assessment of supplier performance is an important activity for small to medium enterprises (SMEs as they adopt and implement plans and policies aimed at enhancing their performance in order to achieve sustainable competitive advantages. Objectives: The purpose of this study was to examine the influence of information sharing, supplier trust and supplier synergy on supplier performance in SMEs. Method: A quantitative research design was adopted in which a survey questionnaire was administered to a sample of 309 owners and managers of SMEs based in southern Gauteng, South Africa. A confirmatory factor analysis was undertaken to assess the properties of the measurement scale. Hypotheses were tested using the path modelling technique. Results: Information sharing exerted a moderate positive and significant influence on supplier trust and a weak but sigificant influence on supplier synergy. Supplier synergy had a strong positive and significant influence on supplier performance. However, the influence of supplier trust on supplier performance was weak and insignificant. Conclusion: The study provides a useful framework for analysing the interplay between information sharing, supplier trust, supplier synergy and supplier performance in SMEs.

    Science.gov (United States)

    Fugkeaw, Somchart; Mitrpanont, Jarernsri L.; Manpanpanich, Piyawit; Juntapremjitt, Sekpon

    This paper proposes the design and development of Role- based Access Control (RBAC) model for the Single Sign-On (SSO) Web-OLAP query spanning over multiple data warehouses (DWs). The model is based on PKI Authentication and Privilege Management Infrastructure (PMI); it presents a binding model of RBAC authorization based on dimension privilege specified in attribute certificate (AC) and user identification. Particularly, the way of attribute mapping between DW user authentication and privilege of dimensional access is illustrated. In our approach, we apply the multi-agent system to automate flexible and effective management of user authentication, role delegation as well as system accountability. Finally, the paper culminates in the prototype system A-COLD (Access Control of web-OLAP over multiple DWs) that incorporates the OLAP features and authentication and authorization enforcement in the multi-user and multi-data warehouse environment.

    The European Commission (Bruessel, Belgium) intensively examined the question, whether electricity tariffs in Germany are formed abusively formed. For this, the centres of the four German energy utilities were examined in the year 2006. A billions-worth penalty against E.ON AG (Duesseldorf, Federal Republic of Germany) could be avoided, because E.ON AG committed itself to the sale of the high-voltage power supply grid and to the sale of power plant capacities. In the Federal Republic of Germany, only few things are done according to the control of electricity tariffs, although the legislator has given an incentive with paragraph 29 of the Law against Restraints of Competition. The author of the contribution under consideration examines the cartel law situation regarding to the price formation at the stock exchange and discusses an increased transparency.

  9. The Role of Trust-building in Fostering Cooperation in the Eastern Nile Basin: A Case of Experimental Game Application

    Directory of Open Access Journals (Sweden)

    Mahsa Motlagh

    2017-09-01

    Full Text Available Escalating tension and a sense of mistrust currently prevail between downstream and upstream countries in the Nile Basin over Ethiopia's construction of the Grand Ethiopian Renaissance Dam (GERD. Striving for self-sufficiency in hydropower generation, Ethiopia has initiated a new series of upstream reservoir construction projects, with the GERD being the largest, and this may affect the water availability in downstream countries of Egypt and Sudan. This paper examines a set of compensation options to induce cooperation through trust-building, possibly minimizing uncertainties in water allocation decision-making and simplifying complex inter-relationships in the basin using laboratory game experiments. The game was developed and conducted using hydro-economic modeling of the basin with GAMS software, an expert survey with the SPSS program and Z-tree software to design and analyze the laboratory experiment. This paper presents the results of the laboratory game experiment where the Eastern Nile Basin scenario was modeled as a multi-round, adjusted trust game with non-binding deals among players. The results suggest that the "win for all" situation may be reached through a stable integrative, cooperative framework. Building the enabling environment, in particular, transparency, knowledge, trust, and confidence among riparian states is the first step in developing transboundary cooperation. Basin-wide cooperation requires a transparent environment including a variety of compensation options, institutional changes, and incentive-compatible considerations.

  16. Can multicriteria assessment tools help build trust into organic products?

    Directory of Open Access Journals (Sweden)

    Bernhard Freyer

    2014-12-01

    Full Text Available In a continuously expanding, globalizing, and industrializing organic market, organic consumers confront increasing complexity in organic product representation, labeling, and information that challenges how they build trust in organic products. We present a conceptual framework to analyze how consumers might build and practice trust in the organic agrifood chain. We asked specifically about the role of multicriteria assessment tools (MCATs for trust building. We identified three consumer trust types: uninformed trust in labels (type 1; informed trust in extensive information, control, and certification (type 2; and informed and engaged trust in forms of close farmer-consumer relationships (type 3. Three concepts of "reflexivity" - unreflective, reflective, self-reflective - are used to explain how these three consumer trust types are operating. We see MCATs as tools accepted and applied mainly by the informed and reflective type. We further examined how reflexivity about two aspects - ethics and systems thinking - in the context of the organic agrifood chain can affect how people trust. Hedonistic, materialistic-oriented consumers might not care about MCATs to deepen their trust in organic, while anthropocentric-oriented consumers were identified as those applying MCATs; eco-centric and holistic-oriented consumers perceive MCATs more as a confinement that limits their self-reflexive and holistic understanding of organic. Awareness of, and interest in, systems thinking by unreflective and uninformed consumer trust types is rather limited; any MCAT is therefore without relevance. The reflective and informed consumer trust type uses a bundle of systems thinking methodologies, and in this context, MCATs would serve as an orientation. The self-reflective, informed, and engaged consumer trust type applies systems theory to learn how to become independent and to better learn how to protect against power interventions; e.g., from industries into the

In this paper I explore how we may understand this change towards high-trust organizations: What does it mean, what is the content of such a change, and what may be the consequences. I show that it is still rather unclear...... what the notion of high-trust organization actually means, and that the change process in the direction of high trust organizations involves not only a quantitative growth in trust, but may involve important qualitative changes in the organization, especially concerning the relations between management...

    Full Text Available Trust can be used to improve online automated recommendation within a given domain. Trust transitivity is used to make it successful. But trust transitivity has different interpretations. Trust and trust transitivity; both are the human mental phenomenon and for this reason, there is no such thing as objective transitivity. Trust transitivity and trust fusion both are important elements in computational trust. This paper analyses the parameter dependence problem in trust transitivity and proposes some definitions considering the effects of base rate. In addition, it also proposes belief functions based on subjective logic to analyse trust transitivity of three specified cases with sensitive and insensitive based rate. Then it presents a quantitative analysis of the effects of unknown dependence problem in an interconnected network environment; such Internet.

  3. Increasing interpersonal trust through divergent thinking

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Interpersonal trust is an essential ingredient of many social relationships but how stable is it actually, and how is it controlled? 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.

    Lewis, Meriel

    1995-01-01

    '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

    Adolescents and young adults (AYA) exposed to family violence are in need of professional healthcare. However, only one-third of them seek professional help. This study investigates healthcare needs of twelve AYA exposed to family violence. Semi-structured face-to-face interviews using purposive sampling to reach diversity. Open thematic coding was used to identify the most important themes. Participants experienced emotional problems, distrusted others and felt unsafe as an important consequence of their exposure to family violence. All participants expressed a need for help, but as help involved informing others, they considered it unsafe. Trust, safety and control regarding healthcare interventions emerged as vital needs. The anonymity of the Internet was considered as offering safeguards in seeking and receiving help. Trust, safety and control regarding healthcare interventions emerged as vital needs for AYA exposed to family violence. The great importance of being in control of healthcare interventions has not been reported earlier. A personal bond can lower the need for control. To comply with the three basic needs, healthcare providers should grant AYA as much control as possible while still monitoring patient safety. The Internet can be an important resource for offering low-threshold professional and peer support. Copyright © 2017 Elsevier B.V. All rights reserved.

    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.

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...

    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.

    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...... into consideration that people often engage in interaction on the basis of familiarity rather than calculation. Finally, the institutionally multi-layered character of social interaction means that trust and calculativeness cannot a priori be separated into non-market and market relations. Rather, it is reasonable...

    2014-08-01

    Observational studies, such as cohort and case-control studies, are valuable instruments in evidence-based medicine. Case-control studies, in particular, are becoming increasingly popular in the neurosurgical literature due to their low cost and relative ease of execution; however, no one has yet systematically assessed these types of studies for quality in methodology and reporting. The authors performed a literature search using PubMed/MEDLINE to identify all studies that explicitly identified themselves as "case-control" and were published in the JNS Publishing Group journals (Journal of Neurosurgery, Journal of Neurosurgery: Pediatrics, Journal of Neurosurgery: Spine, and Neurosurgical Focus) or Neurosurgery. Each paper was evaluated for 22 descriptive variables and then categorized as having either met or missed the basic definition of a case-control study. All studies that evaluated risk factors for a well-defined outcome were considered true case-control studies. The authors sought to identify key features or phrases that were or were not predictive of a true case-control study. Those papers that satisfied the definition were further evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. The search detected 67 papers that met the inclusion criteria, of which 32 (48%) represented true case-control studies. The frequency of true case-control studies has not changed with time. Use of odds ratios (ORs) and logistic regression (LR) analysis were strong positive predictors of true case-control studies (for odds ratios, OR 15.33 and 95% CI 4.52-51.97; for logistic regression analysis, OR 8.77 and 95% CI 2.69-28.56). Conversely, negative predictors included focus on a procedure/intervention (OR 0.35, 95% CI 0.13-0.998) and use of the word "outcome" in the Results section (OR 0.23, 95% CI 0.082-0.65). After exclusion of nested case-control studies, the negative correlation between focus on a procedure

    Victor, Patricia; de Cock, Martine; Cornelis, Chris

    Recommendation technologies and trust metrics constitute the two pillars of trust-enhanced recommender systems. We discuss and illustrate the basic trust concepts such as trust and distrust modeling, propagation and aggregation. These concepts are needed to fully grasp the rationale behind the trust-enhanced recommender techniques that are discussed in the central part of the chapter, which focuses on the application of trust metrics and their operators in recommender systems. We explain the benefits of using trust in recommender algorithms and give an overview of state-of-the-art approaches for trust-enhanced recommender systems. Furthermore, we explain the details of three well-known trust-based systems and provide a comparative analysis of their performance. We conclude with a discussion of some recent developments and open challenges, such as visualizing trust relationships in a recommender system, alleviating the cold start problem in a trust network of a recommender system, studying the effect of involving distrust in the recommendation process, and investigating the potential of other types of social relationships.

    Full Text Available The concept of trust has become popular in public debate andacademic analysis. In high income countries this interest is associatedwith concern for the decline of trust in governments andprofessionals, and in developing countries has been promptedby debates around the motion of social capital. Trust has beenidentified as a major factor influencing such things as capital investment,relationship marketing, cross-cultural communication,learning and various types of cooperation. Trust management isbecoming also very important inside the organization. The studywill review empirical research on organizational trust. The purposeof the study will be also evaluation of the advancements andsetbacks in current empirical research in terms of managementorganizational trust. This paper will analyze the theoretical approach,the conceptualization and the measurement issues coveredin studies on management organizational trust. Althoughtrust has emerged as an important factor in organizational relationships,there are still major conceptual and methodologicalchallenges to be met when studying this complex concept.

    2015-10-01

    Full Text Available There is great interest in the role of management control on theoretical and practical developments within the field of Inter-organizational Relations. This research aims to contribute at verifying how relationships between firms affect the management control tools used, as illustrated in a specific case: the relationship between the franchisor and its franchisees, which has not received much attention to date. As indicated by previous research, case studies can be helpful to determine the factors affecting the type of management control tools that should be established to manage inter-firm relationships. Results have found that the franchisor uses quantitative control mechanisms in order to avoid common types of opportunistic franchise behavior related to royalty payments and other financial requirements, as well as qualitative tools to assure the fulfilment of agreement-related conditions regarding knowhow, to resolve unexpected non-economic problems and to encourage personal relationship and trust. This study also provides an outline on franchisor-franchisee relationships in the model proposed by Van der Meer-Kooistra and Vosselman (2000. To test this model, the franchisor’s perspective (outsourcer has been taken into account as performed when building the model. Findings indicate that this relationship shows many similarities to the pattern based on bureaucracy and a few similarities to patterns based on trust.

    2004-01-01

    The present study examines the relation between client participation in attorney-client relationships, the development of client trust in criminal defense attorneys, and client satisfaction with attorneys and case outcomes. The congruence model of trust development (CMTD) is proposed to explain the relation between desired participation by clients, allowed participation by attorneys, and the development of client trust in attorneys. The CMTD predicts that clients who trust their attorneys will subsequently be satisfied with their attorneys and case outcomes. A sample of 96 experienced criminal defendants currently in prison completed the Attorney-Client Trust Scale (ACTS: Boccaccini and Brodsky, 2002) and provided information about their experiences with their most recent criminal defense attorneys. Findings were generally consistent with the CMTD in suggesting that (i) allowed participation is associated with trust in attorneys, and (ii) trust is associated with satisfaction with attorneys and case outcomes.

  12. Robust control systems theory and case studies

    CERN Document Server

    Mackenroth, Uwe

    2004-01-01

    "Robust Control Systems" gives a self-contained introduction to modern Control Theory. It thus adds a textbook to the existing research-oriented literature on Robust Control. The author lays emphasis on the modern aspects of the design of controllers with prescribed performance and robustness properties. Different to the classical engineering approach, a rigorous mathematical treatment is essential for the full understanding and applicability of the modern methods such as H2 or H8 control or methods based on the structured singular value µ. Nevertheless, no prior knowledge of Control Theory is required as the classical fundamentals are introduced within the first few chapters. Subsequently a large part of the text provides elementary examples and industrial case studies, which are developed in full detail to show how modern methods can be applied to advanced problems. They make intensive use of MATLAB, especially the Control Systems Toolbox and the µ-Analysis and Synthesis Toolbox.

    Case histories are described in which measurable improvements in the cabin noise environments of the Bell 214B, 206B, and 222 were realized. These case histories trace the noise control efforts followed in each vehicle. Among the design approaches considered, the addition of a fluid pulsation damper in a hydraulic system and the installation of elastomeric engine mounts are highlighted. It is concluded that substantial weight savings result when the major interior noise sources are controlled by design, both in altering the noise producing mechanism and interrupting the sound transmission paths.

    Full Text Available OBJECTIVE: Selecting controls is one of the most difficult tasks in the design of case-control studies. Hospital controls may be inadequate and random controls drawn from the base population may be unavailable. The aim was to assess the use of hospital visitors as controls in a case-control study on the association of organochlorinated compounds and other risk factors for breast cancer conducted in the main hospital of the "Instituto Nacional de Câncer" -- INCA (National Cancer Institute in Rio de Janeiro (Brazil. METHODS: The study included 177 incident cases and 377 controls recruited among female visitors. Three different models of control group composition were compared: Model 1, with all selected visitors; Model 2, excluding women visiting relatives with breast cancer; and Model 3, excluding all women visiting relatives with any type of cancer. Odds ratios (OR and 95% confidence intervals were calculated to test the associations. RESULTS: Age-adjusted OR for breast cancer associated with risk factors other than family history of cancer, except smoking and breast size, were similar in the three models. Regarding family history of all cancers, except for breast cancer, there was a decreased risk in Models 1 and 2, while in Model 3 there was an increased risk, but not statistically significant. Family history of breast cancer was a risk factor in Models 2 and 3, but no association was found in Model 1. In multivariate analysis a significant risk of breast cancer was found when there was a family history of breast cancer in Models 2 and 3 but not in Model 1. CONCLUSIONS: These results indicate that while investigating risk factors unrelated to family history of cancer, the use of hospital visitors as controls may be a valid and feasible alternative.

    To describe the processes involved in the selection of cases and controls, and the validation of case diagnosis, in a large case-control study on the association between myocardial infarction (MI) and oral contraceptives. Community case-control study in England, Scotland and Wales. Cases were women aged 16-44 with a diagnosis of MI. Controls were age and general practice matched women without a diagnosis of MI. The proportion of interviewed cases per number eligible was 19% (95% CI 12-26%) lower in England and Wales than in Scotland. The kappa score for agreement between three cardiologists on diagnostic categories of the potential cases was 0.52 overall ('moderate' agreement). For the 35 cases resubmitted for categorization, the kappa scores for agreement between the first and second classification for the two national committee cardiologists were 0.32 and 0.23 ('fair' agreement). Age matching of controls was better in Scotland than England and Wales, the proportion of the first choice controls being 14% (95% CI 8-19%) higher in Scotland. The mean time to complete a cluster of interviews (one case and four controls) was 36 days in Scotland and 63 days in England and Wales. Very close age-matching was achieved overall, although the process was more efficient in Scotland than in England and Wales. Some suggestions for improvement in the case validation process are made.

    Krupa, Yann; Vercouter, Laurent; Hübner, Jomi Fred; Herzig, Andreas

    Wikipedia is an encyclopedia on which anybody can change its content. Some users, self-proclaimed "patrollers", regularly check recent changes in order to delete or correct those which are ruining articles integrity. The huge quantity of updates leads some articles to remain polluted a certain time before being corrected. In this work, we show how a multiagent trust model can help patrollers in their task of controlling the Wikipedia. To direct the patrollers verification towards suspicious contributors, our work relies on a formalisation of Castelfranchi & Falcone's social trust theory to assist them by representing their trust model in a cognitive way.

  5. The decision to trust.

    Science.gov (United States)

    Hurley, Robert F

    2006-09-01

    Surveys have shown that 80% of Americans don't trust corporate executives and--worse--that roughly half of all managers don't trust their own leaders. Mergers, downsizing, and globalization have accelerated the pace of change in organizations, creating a crisis of trust that didn't exist a generation ago. Leaders who understand how trust is built can actively influence its development, resulting in a more supportive and productive work environment and, not incidentally, a competitive advantage in the war for talent. Building on research in social psychology, and on his 15 years of experience consulting on trust, the author has developed a model for predicting whether trust or distrust will be chosen in a given situation. It helps managers analyze ten factors at play in the decision-making process. Hundreds of top executives have used it to diagnose and address the root causes of distrust in their work relationships. Some of the factors in the model relate to the decision maker: How tolerant of risk, how well-adjusted, and how relatively powerful is he or she? Others relate to the specific situation: How closely aligned are the interests of the parties concerned? Does the person who is asking to be trusted demonstrate competence? Predictability and integrity? Frequent and honest communication? Sue, a relatively new VP of sales, used the trust model to manage her relationship with Joe, an employee nearing retirement who was not performing well in a new sales role. Fearing for his job, Joe wasn't initially inclined to trust her. Sue took concrete steps to communicate openly with Joe, explore other options for him, and show concern for his well-being. When joe was transferred, he let his former colleagues know how pleased he was with Sue's handling of the situation. As a result, the level of trust increased in Sue's department, even though it was experiencing major change.

  6. The enemies of trust.

    Science.gov (United States)

    2003-02-01

    Researchers have established that trust is critical to organizational effectiveness. Being trustworthy yourself, however, does not guarantee that you are capable of building trust in an organization. That takes old-fashioned managerial virtues like consistency, clear communication, and a willingness to tackle awkward questions. It also requires a good defense: You must protect trust from its enemies. Any act of bad management erodes trust, so the list of potential enemies is endless. Among the most common enemies of trust, though, are inconsistent messages from top management, inconsistent standards, a willingness to tolerate incompetence or bad behavior, dishonest feedback, a failure to trust others to do good work, a tendency to ignore painful or politically charged situations, consistent corporate underperformance, and rumors. Fending off these enemies must be at the top of every chief executive's agenda. But even with constant vigilance, an organization and its leaders will sometimes lose people's trust. During a crisis, managers should enlist the help of an objective third party--chances are you won't be thinking clearly--and be available physically and emotionally. If you "go dark" in the face of a crisis, employees will worry about the company's survival, about their own capacity to cope, and about your abilities as a leader. And if trust has broken down so badly that your only choice is to start over, you can do so by figuring out exactly how the breach of trust happened, ascertaining the depth and breadth of the loss, owning up to the loss instead of downplaying it, and identifying as precisely as possible the specific changes you must make to rebuild trust.

    DeGrazia, David

    2014-03-01

    In addressing the shape of appropriate gun policy, this essay assumes for the sake of discussion that there is a legal and moral right to private gun ownership. My thesis is that, against the background of this right, the most defensible policy approach in the United States would feature moderate gun control. The first section summarizes the American gun control status quo and characterizes what I call "moderate gun control." The next section states and rebuts six leading arguments against this general approach to gun policy. The section that follows presents a positive case for moderate gun control that emphasizes safety in the home and society as well as rights whose enforcement entails some limits or qualifications on the right to bear arms. A final section shows how the recommended gun regulations address legitimate purposes, rather than imposing arbitrary restrictions on gun rights, and offers concluding reflections.

    Case-control studies are commonly used to evaluate effectiveness of licensed vaccines after deployment in public health programs. Such studies can provide policy-relevant data on vaccine performance under 'real world' conditions, contributing to the evidence base to support and sustain introduction of new vaccines. However, case-control studies do not measure the impact of vaccine introduction on disease at a population level, and are subject to bias and confounding, which may lead to inaccurate results that can misinform policy decisions. In 2012, a group of experts met to review recent experience with case-control studies evaluating the effectiveness of several vaccines; here we summarize the recommendations of that group regarding best practices for planning, design and enrollment of cases and controls. Rigorous planning and preparation should focus on understanding the study context including healthcare-seeking and vaccination practices. Case-control vaccine effectiveness studies are best carried out soon after vaccine introduction because high coverage creates strong potential for confounding. Endpoints specific to the vaccine target are preferable to non-specific clinical syndromes since the proportion of non-specific outcomes preventable through vaccination may vary over time and place, leading to potentially confusing results. Controls should be representative of the source population from which cases arise, and are generally recruited from the community or health facilities where cases are enrolled. Matching of controls to cases for potential confounding factors is commonly used, although should be reserved for a limited number of key variables believed to be linked to both vaccination and disease. Case-control vaccine effectiveness studies can provide information useful to guide policy decisions and vaccine development, however rigorous preparation and design is essential.

  11. Trust and Wellbeing

    This paper presents new evidence linking trust and subjective wellbeing, based primarily on data from the Gallup World Poll and cycle 17 of the Canadian General Social Survey (GSS17. Because several of the general explanations for subjective wellbeing examined here show large and significant linkages to both household income and various measures of trust, it is possible to estimate income-equivalent compensating differentials for different types of trust. Measures of trust studied include general social trust, trust in management, trust in co-workers, trust in neighbours, and trust in police. In addition, some Canadian surveys and the Gallup World Poll ask respondents to estimate the chances that a lost wallet would be returned to them if found by different individuals, including neighbours, police and strangers.

    Our results reveal strong linkages between several trust measures and subjective well-being, as well as strong linkages between social trust and two major global causes of death—suicides and traffic fatalities. This suggests the value of learning more about how trust can be built and maintained, or repaired where it has been damaged. We therefore use data from the Canadian GSS17 to analyze personal and neighbourhood characteristics, including education, migration history, and mobility, that help explain differences in trust

    The growing concern about quality in food products has substantially increased the competitiveness of agro-food products that possess quality-system certifications compared to non-certificated products. This research focused on understanding how consumer trust is greater when agro-food products have a Protected Designation of Origin (PDO). In particular, we analyze whether the influence of consumers’ perceived quality of a PDO product has a direct effect on their perceived risk or whether this relationship is mediated by consumer trust, which can help us advance in the study of consumer behavior within the agro-food marketing discipline. Our findings obtained through the comparison of two models, the proposal and another rival, suggest that the initially proposed model present a better fit and explains the relationships better than the rival model, which highlights the essential role of consumer trust in explaining consumers’ perceived risk and their subsequent purchasing behavior. Consequently, managers should pay special attention to consumer trust because trust is the key mediating aspect which allows the incorporation of characteristics highly valued by consumers in food products like origin, tradition and production methods to reduce perceived risk.

    2003-10-01

    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 (peffect of HMOs is not uniform across all communities. Social 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.

  16. 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.

    2016-02-01

    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.

Owing to its rarity, the diagnosis, staging, and treatment of the disease are not well defined. According to a number of small observational retrospective studies and case reports, the disease’s actual treatment involves surgery, radiotherapy, and/or chemotherapy (either as a single treatment or used in combination, depending on the disease’s staging. Optimal treatment has not been standardized, particularly regarding the role of chemotherapy. We describe a case of advanced esthesioneuroblastoma with prolonged disease control, subjected to a multimodal therapy with surgery, radiotherapy, and chemotherapy, illustrating the benefits of this approach in managing a patient with esthesioneuroblastoma.

    Full Text Available Abstract Background Delayed sleep phase disorder (DSPD is a condition in which patients have difficulty falling asleep before the early morning hours and commonly have trouble awakening before late morning or even early afternoon. Several studies have suggested that variations in habitual bedtime are 40–50% heritable. Methods We recruited a case series of 205 participants, along with 221 controls (DSPD-C with normal sleep, roughly matched for age, gender, and ancestry. A representative sample of San Diego adults recruited some years before was already available to confirm the control group. Both DSPD and DSPD-C provided blood or saliva samples for DNA and completed extensive questionnaires about sleep habits, sleep history, family history, sleep quality, morningness-eveningness traits, depression, mania, and seasonality of symptoms. The DSPD group wore wrist actigraphs for a median of 13.2 days. The representative sample collected previously had undergone actigraphic recordings, from which 48 hours of data were generally available. Results The DSPD and DSPD-C samples showed almost no overlap on morningness-eveningness scores. DSPD cases went to bed and arose about 3 hours later than the DSPD-C and the representative sample. DSPD cases reported more difficulties with sleep, poorer sleep quality, and more depression, but there was no significant difference in a history of mania. DSPD cases reported more family history of late bedtimes, but female DSPD reported that their fathers' bedtimes were later than the fathers of male DSPD. Conclusion These results indicate a DSPD phenotype is familial and associated with unipolar depression.

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.

    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.

    Automated closed loop systems will greatly change type 1 diabetes management; user trust will be essential for acceptance of this new technology. This qualitative study explored trust in 32 individuals following a hybrid closed loop trial. Participants described how context-, system-, and person-level factors influenced their trust in the system. Participants attempted to override the system when they lacked trust, while trusting the system decreased self-management burdens and decreased stress. Findings highlight considerations for fostering trust in closed loop systems. Systems may be able to engage users by offering varying levels of controls to match trust preferences.

    Full Text Available The Tobacco Control Economics Project is a project that seeks to gather evidence on tobacco use and economics in southern Africa. It is a project of the University of Cape Town with support from the DataFirst repository based at the University of Cape Town. Its aim is to gather data that already exists, sometimes in digital form, frequently in offline records or in some cases paper records, and bring them together as an open resource. The project faces challenges of data gathering as well as permissions. Frequently data is or should be “available” in some form but control over the data is relinquished only unreluctantly. In many cases the legal standing of data is unclear. Many of the challenges relating to the bringing together of the data involve ascertaining what the legal standing of a dataset is or gaining permissions for its re-use. DataFirst is a longstanding data sharing infrastructure with professional and experienced data management staff. Challenges of ensuring continued funding and maintenance are similar to those of data infrastructures globally. The infrastructure meets international standards and provides leadership to other services and platforms in this space.

    We undertook a study on a series of laryngeal sarcoidosis (LS), a very rare and often threatening localization to better specify laryngeal manifestations, sarcoidosis clinical expression and long-term follow-up. This was a retrospective case-control study. All LS patients from two French centers were included and compared to sarcoidosis patients without laryngeal localization with two controls for one patient. Twelve consecutive LS patients were recruited between 1993 and 2011. LS revealed sarcoidosis in eight cases (67%). The most common symptoms were hoarseness (77%), inspiratory dyspnea (38%) and dysphagia (38%). Epidemiological characterisics were not different. Extrapulmonary localizations were significantly more common in LS patients than in controls (92% vs. 54%, p=0.02), particularly lupus pernio (25% vs. 0%, p=0.03) and nasosinusal involvement (83% vs. 4%, p<0.01) while thoracic involvement was less frequent (58% vs 100%, p < 0.01). Treatment rates were higher in the LS group (92% vs. 58%, p=0.04), and treatment duration was longer (median: 81 vs. 13 months, p=0.04), with frequent long-term treatment (67%, N=8/12). Two patients underwent surgery. One patient needed temporary tracheostomy during the course of the disease; Remission rates were lower in LS patients (9% vs. 58% at 2 years p<0.01). Eventually, there was no death nor definitive tracheotomy. LS is a rare condition that is often associated to other loco-regional localizations. LS are often difficult to manage. Survival is good but may require a medico-surgical approach.

    2017-09-15

    This paper uses the concepts of organisational culture and organisational trust to explore the implementation of equity-oriented policies - the Uniform Patient Fee Schedule (UPFS) and Patients' Rights Charter (PRC) - in two South African district hospitals. It contributes to the small literatures on organisational culture and trust in low- and middle-income country health systems, and broader work on health systems' people-centeredness and "software". The research entailed semi-structured interviews (Hospital A n = 115, Hospital B n = 80) with provincial, regional, district and hospital managers, as well as clinical and non-clinical hospital staff, hospital board members, and patients; observations of policy implementation, organisational functioning, staff interactions and patient-provider interactions; and structured surveys operationalising the Competing Values Framework for measuring organisational culture (Hospital A n = 155, Hospital B n = 77) and Organisational Trust Inventory (Hospital A n = 185, Hospital B n = 92) for assessing staff-manager trust. Regarding the UPFS, the hospitals' implementation approaches were similar in that both primarily understood it to be about revenue generation, granting fee exemptions was not a major focus, and considerable activity, facility management support, and provincial support was mobilised behind the UPFS. The hospitals' PRC paths diverged quite significantly, as Hospital A was more explicit in communicating and implementing the PRC, while the policy also enjoyed stronger managerial support in Hospital A than Hospital B. Beneath these experiences lie differences in how people's values, decisions and relationships influence health system functioning and in how the nature of policies, culture, trust and power dynamics can combine to create enabling or disabling micro-level implementation environments. Achieving equity in practice requires managers to take account of "unseen" but important factors such as

  10. Trust-based learning and behaviors for convoy obstacle avoidance

    Mikulski, Dariusz G.; Karlsen, Robert E.

    In many multi-agent systems, robots within the same team are regarded as being fully trustworthy for cooperative tasks. However, the assumption of trustworthiness is not always justified, which may not only increase the risk of mission failure, but also endanger the lives of friendly forces. In prior work, we addressed this issue by using RoboTrust to dynamically adjust to observed behaviors or recommendations in order to mitigate the risks of illegitimate behaviors. However, in the simulations in prior work, all members of the convoy had knowledge of the convoy goal. In this paper, only the lead vehicle has knowledge of the convoy goals and the follow vehicles must infer trustworthiness strictly from lead vehicle performance. In addition, RoboTrust could only respond to observed performance and did not dynamically learn agent behavior. In this paper, we incorporate an adaptive agent-specific bias into the RoboTrust algorithm that modifies its trust dynamics. This bias is learned incrementally from agent interactions, allowing good agents to benefit from faster trust growth and slower trust decay and bad agents to be penalized with slower trust growth and faster trust decay. We then integrate this new trust model into a trust-based controller for decentralized autonomous convoy operations. We evaluate its performance in an obstacle avoidance mission, where the convoy attempts to learn the best speed and following distances combinations for an acceptable obstacle avoidance probability.

    Full Text Available Abstract Background The Bacillus thuringiensis (Bt cotton public-private partnership (PPP project in East Africa was designed to gather baseline data on the effect of Bt cotton on biodiversity and the possibility of gene flow to wild cotton varieties. The results of the project are intended to be useful for Kenya, Uganda, and Tanzania when applying for biosafety approvals. Using the backdrop of the different biosafety regulations in the three countries, we investigate the role of trust in the Bt cotton partnership in East Africa. Methods Data were collected by reviewing relevant project documents and peer-reviewed articles on Bt cotton in Tanzania, Kenya and Uganda; conducting face-to-face interviews with key informants of the project; and conducting direct observations of the project. Data were analyzed based on recurring and emergent themes to create a comprehensive narrative on how trust is understood and built among the partners and with the community. Results We identified three factors that posed challenges to building trust in the Bt cotton project in East Africa: different regulatory regimes among the three countries; structural and management differences among the three partner institutions; and poor public awareness of GM crops and negative perceptions of the private sector. The structural and management differences were said to be addressed through joint planning, harmonization of research protocols, and management practices, while poor public awareness of GM crops and negative perceptions of the private sector were said to be addressed through open communication, sharing of resources, direct stakeholder engagement and awareness creation. The regulatory differences remained outside the scope of the project. Conclusions To improve the effectiveness of agbiotech PPPs, there is first a need for a regulatory regime that is acceptable to both the public and private sector partners. Second, early and continuous joint planning; sharing of

    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

Gathering data from such anonymous sources requires a mechanism to establish the integrity of sensor readings. In many cases, sensor data need to be preprocessed on the device itself before being uploaded to the target server while ensuring the chain of trust from capture to the delivery of the data. This can be achieved by a framework that provides a means to implement arbitrary operations to be performed on trusted sensor data, while guaranteeing the security and integrity of the data. This paper presents the design and implementation of a framework that allows the capture of trusted sensor data from both external and internal sensors on a mobile phone along with the development of trusted operations on sensor data while providing a mechanism for performing predefined operations on the data such that the chain of trust is maintained. The evaluation shows that the proposed system ensures the security and integrity of sensor data with minimal performance overhead.

  2. Public trust: Struggle and regain

    International Nuclear Information System (INIS)

    1999-01-01

    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. The struggle may continue for some time

    There is growing evidence that air pollution is associated with increased risk of type 2 diabetes (T2DM). However, information related to whether particulate matter (PM) contributing to worsened metabolic control in T2DM patients is inconsistent. We examined the association of PM 10 exposure with glucose-function parameters in young-onset T2DM patients. We investigated the association between a year ambient concentration of PM 10 at residential places, using AERMOD dispersion model, with fasting plasma glucose (FPG), hemoglobin A1c (HbA1c), 2 h post meal plasma glucose (2hPG), homeostasis model assessment of insulin resistance (HOMA-IR), β-cell function (HOMA-β) and disposition index (DI) in 1213 diabetic patients from the Wellcome Trust Genetic study at the Diabetes Unit, KEM Hospital Research Center, Pune, India. We used linear regression models and adjusted for a variety of individual and environmental confounding variables. Possible effect modification by age, gender, waist-to-hip ratio (WHR) and smoking status were investigated. Sensitivity analysis assessed the impact of relative humidity (RH) and temperature a day before examination and anti-diabetic and HHR medication (Hydralazine, Hydrochlorothiazide and Reserpine). We found that 1 SD increment in background concentration of PM 10 at residential places (43.83 µg/m 3 ) was significantly associated with 2.25 mmol/mol and 0.38 mmol/l increase in arithmetic means of HbA1c and 2hPG, respectively. A similar increase in PM 10 was also associated with 4.89% increase in geometric mean of HOMA-IR. The associations remained significant after adjustment to RH and temperature, and WHR and smoking enhanced the size of the effect. Our study suggests that long-term exposure to PM 10 is associated with higher glycaemia and insulin resistance. In context of our previous demonstration of association of SO 2 and NO x and plasma C-reactive protein, we suggest that air pollution could influence progression of

    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.

For all empirical researches so far have shown very law degree of this trust many authors were searching for the causes of this phenomenon. Among multifold causes some are special worth while to be mentioned here: historical inheritance, political pressures, delaying of judiciary decisions, respect of the laws, transferring of responsibility from political power to the judiciary, public comments of judiciary decisions, media pressures, efficiency of judiciary and police. Among inner factors author pays attention to competency of judges, modes of penal policy, modes of judges’ entitlement, problems of communication, involvement into criminal and corruptional affairs, etc.

  13. Capturing Trust in Social Web Applications

    Science.gov (United States)

    O'Donovan, John

    The Social Web constitutes a shift in information flow from the traditional Web. Previously, content was provided by the owners of a website, for consumption by the end-user. Nowadays, these websites are being replaced by Social Web applications which are frameworks for the publication of user-provided content. Traditionally, Web content could be `trusted' to some extent based on the site it originated from. Algorithms such as Google's PageRank were (and still are) used to compute the importance of a website, based on analysis of underlying link topology. In the Social Web, analysis of link topology merely tells us about the importance of the information framework which hosts the content. Consumers of information still need to know about the importance/reliability of the content they are reading, and therefore about the reliability of the producers of that content. Research into trust and reputation of the producers of information in the Social Web is still very much in its infancy. Every day, people are forced to make trusting decisions about strangers on the Web based on a very limited amount of information. For example, purchasing a product from an eBay seller with a `reputation' of 99%, downloading a file from a peer-to-peer application such as Bit-Torrent, or allowing Amazon.com tell you what products you will like. Even something as simple as reading comments on a Web-blog requires the consumer to make a trusting decision about the quality of that information. In all of these example cases, and indeed throughout the Social Web, there is a pressing demand for increased information upon which we can make trusting decisions. This chapter examines the diversity of sources from which trust information can be harnessed within Social Web applications and discusses a high level classification of those sources. Three different techniques for harnessing and using trust from a range of sources are presented. These techniques are deployed in two sample Social Web

    2001-01-01

    It is important for decision makers to be aware of public concern for health risks in order that risk management decisions properly reflect such concern and ultimately receive public acceptance. The problem is that of scientists and technologists base their beliefs, and consequently their approach to the evaluation of risk, on experimental evidence, scientific theories, models, control systems etc. whereas the public have to rely on the interpretations of this information by spokesmen of public bodies, interest groups such as industrial and consumer organisations and media reports. In either case attitudes are no less real since decisions that are taken in the public domain are taken in a social rather than technological context. Attitudes to food safety questions are strongly influenced by national food culture, the development of commerce in the country concerned and the organisation of its implementation by government. To understand the public attitudes and how to manage them, several cases have been reported: salmonella in eggs was a crisis sparked off by government action (U.K.), the Alar affair where activists created a false crisis (U.S.A.), the Crohn's disease or media amplification of risk (U.K.), Bovine Spongi-form Encephalopathy considered as a betrayal of trust (U.K.).

    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.

  17. Competence Utilization for Innovation Capabilities - A Question of Trust?

    Directory of Open Access Journals (Sweden)

    Britta BOLZERN-KONRAD

    2015-05-01

    Full Text Available The purpose of this paper is to show how trust as an organizational value contributes to employee competence utilization in the case of innovation capability. Thus, it is the objective of this paper to analyze the positive impacts, but also potential limits of trust in business management. The research paper uses two different quantitative empirical studies drawn from German and Austrian mid-sized companies to empirically test this interrelation. As a result, the paper determines particular aspects of trust such as accountability, shared norms and the ability to take responsibility to be interrelated with the usage of employee competences and underlines a positive connection between product innovation performance and trust. However, the trust concept needs enriching elements to be balanced towards a feeling of mutual reliance and support creativity instead; inclusions of bridging social capital, elements of distrust and a pioneering spirit are to be mentioned here.

    2016-11-01

    The case-control study design is deceptively simple. However, many design considerations influence the estimated effect measure. An investigation of case-control studies in the human health literature suggested that some of these considerations are not described in reports of case-control studies. Our hypothesis was that the majority of veterinary studies labeled as case-controls would be incident density designs, and many would not interpret the effect measure obtained from those studies as the rate ratio rather than the odds ratio. Reference databases were searched for author-designated case-control studies. A survey of 100 randomly selected studies was conducted to examine the different design options described and estimated effect measures. Of the 100 author-identified case-control studies, 83 assessed an exposure-outcome association and, of those, only 54 (65.1%) sampled the study population based on an outcome and would thus be considered case-control designs. Twelve studies were incidence density designs but none used this terminology. Of the studies that reported an odds ratio as the effect measure, none reported on additional considerations that would have enabled a more interpretable result. This survey indicated many case-control-labeled studies were not case-control designs and among case-control studies, key design aspects were not often described. The absence of information about study design elements and underlying assumptions in case-control studies limits the ability to establish the effect measured by the study and the evidentiary value of the study might be underestimated.

    2014-01-01

    Full Text Available Feedback based reputation systems continue to gain popularity in eCommerce and social media systems today and reputation management in large social networks needs to manage cold start and sparseness in terms of feedback. Trust propagation has been widely recognized as an effective mechanism to handle these problems. In this paper we study the characterization of trust propagation models in the context of attack resilience. We characterize trust propagation models along three dimensions: (i uniform propagation and conditional propagation, (ii jump strategies for breaking unwanted cliques, and (iii decay factors for differentiating recent trust history from remote past history. We formally and experimentally show that feedback similarity is a critical measure for countering colluding attacks in reputation systems. Without feedback similarity guided control, trust propagations are vulnerable to different types of colluding attacks.

    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

  8. Social Trust and Children Born of War

    Directory of Open Access Journals (Sweden)

    Voicu Bogdan

    2014-12-01

    Full Text Available This paper considers two assumptions commonly used in analyzing the formation of social trust. They stress the importance of early socialization, on one hand, and of life events, on the other. We consider birth as a major life event for anyone and focus on the situation of Children Born of War. This group, even if lesser visible in some societies, has the peculiar characteristic to be born and socialized in very specific conditions. Typically, these people are the offspring of foreign soldiers, and local women. They may bear stigma, might be marginalized in family, school and society, and might develop a low level of generalized trust even if they may have lived all life in a culture rich in social trust. We explore at theoretical level their case, bring in a few statistics, and suggest a research direction that may be fruitful in learning about both such hidden populations and about social trust. In the end, we argue upon the importance of the topic for post-conflict societies.

    Unintentional falls from windows are an important cause of paediatric morbidity. There have been no controlled studies to identify modifiable environmental risk factors for window falls in young children. The authors have piloted a case-control study to test procedures for case identification, subject enrolment, and environmental data collection. Case windows were identified when a child 0-9 years old presented for care after a fall from that window. Control windows were identified (1) from the child's home and (2) from the home of an age- and gender-matched child seeking care for an injury diagnosis not related to a window fall. Study staff visited enrolled homes to collect window measurements and conduct window screen performance tests. The authors enrolled and collected data on 18 case windows, 18 in-home controls, and 14 matched community controls. Six potential community controls were contacted for every one enrolled. Families who completed the home visit viewed study procedures positively. Case windows were more likely than community controls to be horizontal sliders (100% vs 50%), to have deeper sills (6.28 vs 4.31 inches), to be higher above the exterior surface (183 vs 82 inches), and to have screens that failed below a threshold derived from the static pressure of a 3-year-old leaning against the mesh (60.0% vs 16.7%). Case windows varied very little from in-home controls. Case-control methodology can be used to study risk factors for paediatric falls from windows. Recruitment of community controls is challenging but essential, because in-home controls tend to be over-matched on important variables. A home visit allows direct measurement of window type, height, sill depth, and screen performance. These variables should all be investigated in subsequent, larger studies covering major housing markets.

    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.

    Susan Martins Pereira

    Full Text Available ABSTRACT OBJECTIVE To test the association between diabetes and tuberculosis. METHODS It is a case-control study, matched by age and sex. We included 323 new cases of tuberculosis with positive results for bacilloscopy. The controls were 323 respiratory symptomatic patients with negative bacilloscopy, from the same health services, such as: ambulatory cases from three referral hospitals and six basic health units responsible for the notifications of new cases of tuberculosis in Salvador, Bahia. Data collection occurred between 2008 and 2010. The instruments used were structured interview, including clinical data, capillary blood glucose (during fasting or postprandial, and the CAGE questionnaire for screening of abusive consumption of alcohol. Descriptive, exploratory, and multivariate analysis was performed using conditional logistic regression. RESULTS The average age of the cases was 38.5 (SD = 14.2 years and of the controls, 38.5 (SD = 14.3 years. Among cases and controls, most subjects (61% were male. In univariate analysis we found association between the occurrence of diabetes and tuberculosis (OR = 2.37; 95%CI 1.04–5.42, which remained statistically significant after adjustment for potential confounders (OR = 3.12; 95%CI 1.12–7.94. CONCLUSIONS The association between diabetes and tuberculosis can hinder the control of tuberculosis, contributing to the maintainance of the disease burden. The situation demands increasing early detection of diabetes among people with tuberculosis, in an attempt to improve disease control strategies.

    Full Text Available Abstract Background In haplotype-based candidate gene studies a problem is that the genotype data are unphased, which results in haplotype ambiguity. The measure 1 quantifies haplotype predictability from genotype data. It is computed for each individual haplotype, and for a measure of global relative efficiency a minimum value is suggested. Alternatively, we developed methods directly based on the information content of haplotype frequency estimates to obtain global relative efficiency measures: and based on A- and D-optimality, respectively. All three methods are designed for single populations; they can be applied in cases only, controls only or the whole data. Therefore they are not necessarily optimal for haplotype testing in case-control studies. Results A new global relative efficiency measure was derived to maximize power of a simple test statistic that compares haplotype frequencies in cases and controls. Application to real data showed that our proposed method gave a clear and summarizing measure for the case-control study conducted. Additionally this measure might be used for selection of individuals, who have the highest potential for improving power by resolving phase ambiguity. Conclusion Instead of using relative efficiency measure for cases only, controls only or their combined data, we link uncertainty measure to case-control studies directly. Hence, our global efficiency measure might be useful to assess whether data are informative or have enough power for estimation of a specific haplotype risk.

    Objective: To evaluate and compare the effects of pre-operative single oral dose of tramadol and famotidine on gastric secretions pH and volume in patients electively scheduled for laparoscopic cholecystectomy. Study Design:Randomized control trial. Place and Duration of Study: Department of Anaesthesia, King Saud University Riyadh, Saudi Arabia, from August 2011 to June 2013. Methodology:Ninety adult, ASA-I and II patients scheduled for laparoscopic cholecystectomy were included in the study. Patients were randomly assigned to receive pre-operatively either placebo (Group-C, n=30), oral tramadol 100 mg (Group-T, n=30) or famotidine 40 mg (Group-F, n=30). After induction of general anaesthesia, gastric fluid was aspirated through orogastric tube. The gastric secretions volume and pH was measured using pH meter. Results: There was no statistically difference between groups in age, weight and gender. The gastric secretions mean pH was 2.06 ± 0.22,2.04 ± 0.20, 5.79 ± 0.77 and volume was 0.59 ± 0.17, 0.59 ± 0.14 and 0.28 ± 0.16 ml/kg in Group-C, Group-T and Group-F respectively. There was a significant statistical difference in the mean pH values between Group-C vs. Group-F (p greater than 0.001) and Group-Tvs. Group-F (p greater than 0.001). Statistically significant difference was also found in the mean gastric secretions volume between Group - C vs. Group-F (p greater than 0.001) and Group-Tvs. Group-F (p greater than 0.001). There was no significant difference in the mean gastric fluid pH values (p=0.99) and mean gastric secretions volume (p=0.99) between Group-T and Group-C. Conclusion:As compared to famotidine, pre-operative single oral dose of tramadol was unable to elevate the desired level of gastric fluid pH (less than 2.5) and decrease in gastric secretions volume (greater than 0.4ml/kg).

    Paul R Ward

    Full Text Available BACKGROUND: Trust is regarded as a necessary component for the smooth running of society, although societal and political modernising processes have been linked to an increase in mistrust, potentially signalling social and economic problems. Fukuyama developed the notion of 'high trust' and 'low trust' societies, as a way of understanding trust within different societies. The purpose of this paper is to empirically test and extend Fukuyama's theory utilising data on interpersonal trust in Taiwan, Hong Kong, South Korea, Japan, Australia and Thailand. This paper focuses on trust in family, neighbours, strangers, foreigners and people with a different religion. METHODS: Cross-sectional surveys were undertaken in 2009-10, with an overall sample of 6331. Analyses of differences in overall levels of trust between countries were undertaken using Chi square analyses. Multivariate binomial logistic regression analysis was undertaken to identify socio-demographic predictors of trust in each country. RESULTS: Our data indicate a tripartite trust model: 'high trust' in Australia and Hong Kong; 'medium trust' in Japan and Taiwan; and 'low trust' in South Korea and Thailand. Trust in family and neighbours were very high across all countries, although trust in people with a different religion, trust in strangers and trust in foreigners varied considerably between countries. The regression models found a consistent group of subpopulations with low trust across the countries: people on low incomes, younger people and people with poor self-rated health. The results were conflicting for gender: females had lower trust in Thailand and Hong Kong, although in Australia, males had lower trust in strangers, whereas females had lower trust in foreigners. CONCLUSION: This paper identifies high, medium and low trust societies, in addition to high and low trusting population subgroups.

    This study examined a knowledge-centered theory of institutional trust development. In the context of trust in water regulatory institutions, the moderating impact of knowledge was tested to determine if there were longitudinal changes in the bases of institutional trust as a function of increases in knowledge about a target institution. We hypothesized that as people learn about an institution with which they were previously unfamiliar, they begin to form more nuanced perceptions, distinguishing the new institution from other institutions and relying less upon their generalized trust to estimate their trust in that institution. Prior to having specific, differential information about a new institution, we expected institutional trust to be a function of generalized trust variables such as dispositional trust and trust in government. The longitudinal experiment involved 185 college students randomly assigned to one of three information conditions. Every 3 months for 15 months, participants read information about water regulatory institutions or a control institution. At each time point, participants reported their trust in and perceptions of the trust- and distrust-worthiness of the water regulatory institutions. Participants also completed measures of knowledge of water regulatory institutions, dispositional trust, and governmental trust. Our manipulation check indicated that, as expected, those in the experimental group increased in subjective knowledge of water regulatory institutions to a greater extent than those in the control condition. Consistent with our hypotheses, there was some evidence that, compared to the control group, the experimental group relied less on their general trust in government as a basis for their trust in water regulatory institutions. However, contrary to our hypotheses, there was no evidence the experimental group relied less on dispositional trust as a basis for institutional trust. There also was some evidence the experimental

    Hartong, Mark; Goel, Rajni; Wijesekera, Duminda

    Forensic analysis helps identify the causes of crimes and accidents. Determination of cause, however, requires detailed knowledge of a system's design and operational characteristics. This paper advocates that "use cases," which specify operational interactions and requirements, and "misuse cases," which specify potential misuse or abuse scenarios, can be used to analyze and link forensic evidence and create postincident reconstructions. Use-misuse case analysis techniques involving non-probabilistic and probabilistic methods are described and applied to Positive Train Control (PTC) Systems — a network-based automated system that controls the movements of passenger and freight trains.

  6. Assessing Trust and Effectiveness in Virtual Teams: Latent Growth Curve and Latent Change Score Models

    Directory of Open Access Journals (Sweden)

    Michael D. Coovert

    2017-08-01

    Full Text Available Trust plays a central role in the effectiveness of work groups and teams. This is the case for both face-to-face and virtual teams. Yet little is known about the development of trust in virtual teams. We examined cognitive and affective trust and their relationship to team effectiveness as reflected through satisfaction with one’s team and task performance. Latent growth curve analysis reveals both trust types start at a significant level with individual differences in that initial level. Cognitive trust follows a linear growth pattern while affective trust is overall non-linear, but becomes linear once established. Latent change score models are utilized to examine change in trust and also its relationship with satisfaction with the team and team performance. In examining only change in trust and its relationship to satisfaction there appears to be a straightforward influence of trust on satisfaction and satisfaction on trust. However, when incorporated into a bivariate coupling latent change model the dynamics of the relationship are revealed. A similar pattern holds for trust and task performance; however, in the bivariate coupling change model a more parsimonious representation is preferred.

  7. Model of trust in work groups

    Sidorenkov, Andrey V.

    2013-09-01

    Full Text Available A multi-dimensional model of trust in a small group has been developed and approved. This model includes two dimensions: trust levels (interpersonal trust, micro-group trust, group trust, trust between subgroups, trust between subgroups and group and types of trust (activity-coping, information-influential and confidentially-protective trust. Each level of trust is manifested in three types, so there are fifteen varieties of trust. Two corresponding questionnaires were developed for the study. 347 persons from 32 work groups participated in the research. It was determined that in a small group there is an asymmetry of trust levels within the group. In particular, micro-group trust is demonstrated the most in comparison with other trust levels. There is also an asymmetry in the manifestation of interpersonal trust in a group structure. This is demonstrated by the fact that in informal subgroups, in comparison with a group as a whole, interpersonal confidential and performance trust is the most manifested. In a small group and in informal subgroups there are relationships between trust levels which have certain regularities.

    2012-01-01

    Background Neuropsychiatric findings described in essential tremor (ET) include depression and anxiety. There may be personality features as well; in 2004, we demonstrated higher harm avoidance (HA) scores in ET patients than controls. We now (1) determined whether this finding could be replicated in a new sample of cases and controls, and (2) analyzed HA sub-scores (HA1–HA4) to further understand case-control differences. Design/Methods 60 ET cases and 35 controls were evaluated using the Tridimensional Personality Questionnaire (TPQ), which assesses three domains of personality: HA, novelty seeking (NS), and reward dependence (RD). Results Total HA and total NS scores were marginally higher in cases than controls (14.8 ± 7.6 vs. 12.4 ± 5.3, p = 0.09) and (13.8 ± 5.4 vs. 11.8 ± 4.9, p = 0.09), respectively. When adjusted for age and gender, cases and controls differed with respect to total HA score (p = 0.03) but not total NS score (p = 0.10). Further analysis of HA subscores demonstrated that HA1 (anticipatory worry and pessimism) and HA4 (fatigability and asthenia) were most robustly elevated in cases vs. controls (p = 0.04 and p = 0.01, respectively). Conclusions This study suggests that ET cases have a personality profile characterized by a greater HA, with certain domains of HA most affected. It is unclear whether this personality profile is pre-morbid or is a co-morbid feature of the illness, nor it is known whether the greater tendency towards HA in ET lessens receptivity to deep brain stimulation surgery and other therapies.

  11. Delaying gratification depends on social trust

    2013-06-01

    Full Text Available Delaying gratification is hard, yet predictive of important life outcomes, such as academic achievement and physical health. Prominent theories focus on the role of self-control, hypersensitivity to immediate rewards, and the cost of time spent waiting. However, delaying gratification may also require trust in people delivering future rewards as promised. To test the role of social trust, participants were presented with character vignettes and faces that varied in trustworthiness, and then chose between hypothetical smaller immediate or larger delayed rewards from those characters. Across two experiments, participants were less willing to wait for delayed rewards from less trustworthy characters, and perceived trustworthiness predicted willingness to delay gratification. These findings provide the first demonstration of a causal role for social trust in willingness to delay gratification, independent of other relevant factors, such as self-control or reward history. Thus, delaying gratification requires choosing not only a later reward, but a reward that is potentially less likely to be delivered, when there is doubt about the person promising it. Implications of this work include the need to revise prominent theories of delay of gratification, and new directions for interventions with populations characterized by impulsivity.

  12. Trusted counsellor retires

    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.

  14. 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

    Theoretically, there are strong arguments for a relationship between cyberbullying and trust. On the one hand, trust is built on experiences; thus, experiences of malevolence such as cyberbullying might contribute to low trust. On the other hand, high trust may lead to risky online behavior such as self-disclosures that could increase the risk of…

    2017-01-01

    To achieve high safety levels, mere compliance with safety regulations is not sufficient; employees must be proactive and demonstrate safety citizenship behaviors. Trust is considered as a mechanism for facilitating the effects of a leader on employee citizenship behaviors. Increasingly research has focused on the role of trust in a safety context; however, the role of coworker trust has been overlooked. The mediating role of coworker trust in the relationship between the leader-member exchange and safety citizenship behavior is the focus of this field study. Front-line employees from an air traffic control center and an airline maintenance department completed surveys measuring leader-member exchange, co-worker trust, and safety citizenship behavior. Structural Equation Modeling revealed affective and cognitive trust in coworkers is influenced by leader-member exchange. A trust-based mediation model where cognitive trust and affective trust mediate the relationship between the leader-member exchange and safety citizenship behavior emerged. Results of this study add to our understanding of the relationship between leader-member exchange and safety behavior. The effect of co-worker trust and the extent to which employees participate in workplace safety practice were identified as critical factors. The findings show that managers need to focus on developing cognitive and affective coworker trust to improve safety citizenship behaviors.

  2. Trust and Online Reputation Systems

    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.

  3. Bridging case-control studies and randomized trials

    2001-05-01

    Full Text Available Abstract Randomized trials and observational studies, such as case-control studies, are often seen as opposing approaches. However, in many instances results obtained by different designs may complement each other. For instance, case-control studies on aetiology of disease may help to give the direction of future trials. In this commentary, the author discusses the purpose of randomization and observation, and under which conditions one design may be preferred to another. Randomization is useful to combat 'confounding by indication', and is therefore the design of choice for most therapeutic trials. When this confounding is not an issue, as in studies of genetic risk factors or side-effects, then case-control studies are preferred.

    2012-09-01

    Full Text Available This article focuses on opportunities for citizens to interact with public organisations in the processing of individual cases and how this interaction is facilitated by the Internet. We analysed a string of messages from the online forum of the non-governmental organisation Marriage without Borders, which offers dialogue-based advice to members looking for help prior with the complex application process in relation to family reunification visas in Denmark. The trajectory of the problem-solving interaction clearly demonstrates the Internet’s potential for dynamic online interaction, emphasising the timeliness of a joint accomplishment. Our findings also emphasise the potential of non-governmental web forums to address the needs of member publics and to serve as equalisers in relation to the power gap between the more powerful public authorities and the less powerful individuals. A recurrent theme running through these posts is that you trust the members of the community to help as best they can and that expertise is not allocated to the authorities alone.

  7. An Operational Semantics for Trust Policies

    2005-01-01

    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...

    2016-03-01

    The South London and Maudsley National Health Service (NHS) Foundation Trust Biomedical Research Centre (SLaM BRC) Case Register and its Clinical Record Interactive Search (CRIS) application were developed in 2008, generating a research repository of real-time, anonymised, structured and open-text data derived from the electronic health record system used by SLaM, a large mental healthcare provider in southeast London. In this paper, we update this register's descriptive data, and describe the substantial expansion and extension of the data resource since its original development. Descriptive data were generated from the SLaM BRC Case Register on 31 December 2014. Currently, there are over 250,000 patient records accessed through CRIS. Since 2008, the most significant developments in the SLaM BRC Case Register have been the introduction of natural language processing to extract structured data from open-text fields, linkages to external sources of data, and the addition of a parallel relational database (Structured Query Language) output. Natural language processing applications to date have brought in new and hitherto inaccessible data on cognitive function, education, social care receipt, smoking, diagnostic statements and pharmacotherapy. In addition, through external data linkages, large volumes of supplementary information have been accessed on mortality, hospital attendances and cancer registrations. Coupled with robust data security and governance structures, electronic health records provide potentially transformative information on mental disorders and outcomes in routine clinical care. The SLaM BRC Case Register continues to grow as a database, with approximately 20,000 new cases added each year, in addition to extension of follow-up for existing cases. Data linkages and natural language processing present important opportunities to enhance this type of research resource further, achieving both volume and depth of data. However, research projects still

    As a devastating Ebola outbreak in West Africa continues, non-pharmaceutical control measures including contact tracing, quarantine, and case isolation are being implemented. In addition, public health agencies are scaling up efforts to test and deploy candidate vaccines. Given the experimental nature and limited initial supplies of vaccines, a mass vaccination campaign might not be feasible. However, ring vaccination of likely case contacts could provide an effective alternative in distributing the vaccine. To evaluate ring vaccination as a strategy for eliminating Ebola, we developed a pair approximation model of Ebola transmission, parameterized by confirmed incidence data from June 2014 to January 2015 in Liberia and Sierra Leone. Our results suggest that if a combined intervention of case isolation and ring vaccination had been initiated in the early fall of 2014, up to an additional 126 cases in Liberia and 560 cases in Sierra Leone could have been averted beyond case isolation alone. The marginal benefit of ring vaccination is predicted to be greatest in settings where there are more contacts per individual, greater clustering among individuals, when contact tracing has low efficacy or vaccination confers post-exposure protection. In such settings, ring vaccination can avert up to an additional 8% of Ebola cases. Accordingly, ring vaccination is predicted to offer a moderately beneficial supplement to ongoing non-pharmaceutical Ebola control efforts.

  12. Globalization and Trust: Non-financial Information

    Oscar Banda Lefaure

    2015-09-01

    Full Text Available Changes in the way of doing business that have resulted from globalization of markets have enabled countless benefits, but also a significant number of risks, that have been evident as since 2001 revelations about financial scandals around the world have occurred one after another. These unfortunate events showed the vulnerability to which investors (and other stakeholders are exposed for not having timely, clear and accurate information of the business progress in which they invest, and therefore not being able to take precautions. In addition, these business disasters have shown how the most unscrupulous executives do not hesitate to act illegally to hide their shady financial and accounting manoeuvres, in order to promote their personal benefit. Then the executive compensations policy lies behind. At this juncture, the importance of migrating to a new model of disclosure where the global financial community can take shelter of these malpractices and trust the board controls and the management stablishes has been increasing. This new model of disclosure has one of its pillars in non-financial information reports. This is not an alchemist solution, but is one of many efforts to be undertaken by companies to recover damaged trust. The international financial crisis affecting the world economy at the moment is another example of the need to give greater trust to the stakeholders –through transparency in the information they provide–. Only then, their participation in the capital market will be maintained and increased, and the costs that brings widespread lack of trust in which we live will be reduced.

    2007-11-01

    Full Text Available Abstract Background Premature labor is a poorly understood condition. Estrogen is thought to play a key role and therefore the labor process may be affected by endocrine disruptors. We sought to determine whether or not an environmental toxicant, DDE, or dietary derived endocrine disruptors, daidzein and genistein, are associated with spontaneous preterm labor. Methods Cases were defined as primiparous patients having a preterm delivery at or before 35 weeks following the spontaneous onset of labor. Controls were defined as primiparous women who delivered on the same day as the cases but at term gestation. Over approximately 1 year, 26 cases and 52 controls were recruited. Subjects agreed to have blood tests on day one postpartum for DDE and for the phytoestrogens genistein and daidzein. Results The mean concentration of DDE was similar in the case and control groups: 4.29 vs 4.32 ng/g lipid p = .85. In the case group, 13/26 had detectable levels of daidzein (range 0.20 – 1.56 ng/ml compared to 25/52 controls (range 0.21 – 3.26 ng/ml. The mean concentration of daidzein was similar in cases compared to controls: 0.30 vs .34 ng/ml p = 0.91. Of the case group,14/26 had detectable levels of genistein (range 0.20 – 2.19 ng/ml compared to 32/52 controls (range 0.21 – 2.55 ng/ml. The mean concentration of genistein was similar in cases compared to controls: 0.39 vs 0.31 ng/ml, p = 0.61. Conclusion The serum levels of DDE in this population were found to be low. There appears to be no relationship between serum concentrations of DDE, daidzein, and genistein and spontaneous preterm labor in our population. The inability to identify an effect may be related to the comparatively low concentrations of DDE in our population and the rapid and variable reduction of phytoestrogens from women in labor.

  14. A Cloud Theory-Based Trust Computing Model in Social Networks

    Fengming Liu

    2016-12-01

    Full Text Available How to develop a trust management model and then to efficiently control and manage nodes is an important issue in the scope of social network security. In this paper, a trust management model based on a cloud model is proposed. The cloud model uses a specific computation operator to achieve the transformation from qualitative concepts to quantitative computation. Additionally, this can also be used to effectively express the fuzziness, randomness and the relationship between them of the subjective trust. The node trust is divided into reputation trust and transaction trust. In addition, evaluation methods are designed, respectively. Firstly, the two-dimension trust cloud evaluation model is designed based on node’s comprehensive and trading experience to determine the reputation trust. The expected value reflects the average trust status of nodes. Then, entropy and hyper-entropy are used to describe the uncertainty of trust. Secondly, the calculation methods of the proposed direct transaction trust and the recommendation transaction trust involve comprehensively computation of the transaction trust of each node. Then, the choosing strategies were designed for node to trade based on trust cloud. Finally, the results of a simulation experiment in P2P network file sharing on an experimental platform directly reflect the objectivity, accuracy and robustness of the proposed model, and could also effectively identify the malicious or unreliable service nodes in the system. In addition, this can be used to promote the service reliability of the nodes with high credibility, by which the stability of the whole network is improved.

    Full Text Available Abstract Background Correct control selection is crucial to the internal validity of case-control studies. Little information exists on differences between population and hospital controls in case-control studies on cancers in Chinese hospital setting. Methods We conducted three parallel case-control studies on leukemia, breast and colorectal cancers in China between 2009 and 2010, using population and hospital controls to separately match 540 incident cases by age, gender and residency at a 1:1 ratio. Demographic and lifestyle factors were measured using a validated questionnaire in face-to-face interview.

    Correct control selection is crucial to the internal validity of case-control studies. Little information exists on differences between population and hospital controls in case-control studies on cancers in Chinese hospital setting. We conducted three parallel case-control studies on leukemia, breast and colorectal cancers in China between 2009 and 2010, using population and hospital controls to separately match 540 incident cases by age, gender and residency at a 1:1 ratio. Demographic and lifestyle factors were measured using a validated questionnaire in face-to-face interview. Odds ratios (ORs) and 95% confidence intervals (CIs) were obtained using conditional logistic regression analyses. The two control groups had closely similar exposure distributions of 15 out of 16 factors, with the only exception being that hospital controls were less likely to have a BMI ≥ 25 (OR = 0.71, 95% CI: 0.54, 0.93).

    Misconceptions about the impact of case-control matching remain common. We discuss several subtle problems associated with matched case-control studies that do not arise or are minor in matched cohort studies: (1) matching, even for non-confounders, can create selection bias; (2) matching distorts dose-response relations between matching variables and the outcome; (3) unbiased estimation requires accounting for the actual matching protocol as well as for any residual confounding effects; (4) for efficiency, identically matched groups should be collapsed; (5) matching may harm precision and power; (6) matched analyses may suffer from sparse-data bias, even when using basic sparse-data methods. These problems support advice to limit case-control matching to a few strong well-measured confounders, which would devolve to no matching if no such confounders are measured. On the positive side, odds ratio modification by matched variables can be assessed in matched case-control studies without further data, and when one knows either the distribution of the matching factors or their relation to the outcome in the source population, one can estimate and study patterns in absolute rates. Throughout, we emphasize distinctions from the more intuitive impacts of cohort matching.

    Various fundamental phenomena of strongly correlated quantum systems such as high-Tc superconductivity, the fractional quantum-Hall effect and quark confinement are still awaiting a universally accepted explanation. The main obstacle is the computational complexity of solving even the most simplified theoretical models which are designed to capture the relevant quantum correlations of the many-body system of interest. In his seminal 1982 paper (Feynman 1982 Int. J. Theor. Phys. 21 467), Richard Feynman suggested that such models might be solved by ‘simulation’ with a new type of computer whose constituent parts are effectively governed by a desired quantum many-body dynamics. Measurements on this engineered machine, now known as a ‘quantum simulator,’ would reveal some unknown or difficult to compute properties of a model of interest. We argue that a useful quantum simulator must satisfy four conditions: relevance, controllability, reliability and efficiency. We review the current state of the art of digital and analog quantum simulators. Whereas so far the majority of the focus, both theoretically and experimentally, has been on controllability of relevant models, we emphasize here the need for a careful analysis of reliability and efficiency in the presence of imperfections. We discuss how disorder and noise can impact these conditions, and illustrate our concerns with novel numerical simulations of a paradigmatic example: a disordered quantum spin chain governed by the Ising model in a transverse magnetic field. We find that disorder can decrease the reliability of an analog quantum simulator of this model, although large errors in local observables are introduced only for strong levels of disorder. We conclude that the answer to the question ‘Can we trust quantum simulators?’ is … to some extent.

  8. Historical Roots of Generalized Trust in Polish Society

    Directory of Open Access Journals (Sweden)

    Borowiecki Łukasz

    2014-11-01

    Full Text Available The article analyses how historical events shape generalized trust in contemporary Polish society. The analysis consists of a set of logistic regression models. The impact of historical variables is controlled for age, sex, education and the size of the municipality. This is the first quantitative study on Poland that links historical events with the current levels of trust among Polish citizens. The common knowledge is that the Partitions of Poland had negative impact on trust. Literature on the topic hints that historical demo? graphics should play a role too. The findings suggest that Partitions had little impact with only Greater Poland and Pomerania having lower levels of generalized trust. Historical literacy rate and the presence of Ukrainian or Belarusian population are negatively associated with generalized trust while the abrupt migrations after the World War I are positively associated. The rapid character of migration is supposed to positively impact generalized trust by forcing individuals to cooperate and rely on people with whom they have no personal ties.

  9. Social trust and ionizing radiation

    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

    The introduction of alternative energy requires collaboration between consumers, energy suppliers and regulators. A fundamental question is, will consumers engage with this agenda and, in particular, will they trust the institutions sufficiently to enable the collaborations that are needed. Present indications suggest that consumers have little trust in the established institutions and tend to reject such collaborations. This article presents two case studies which explore the way consumers, regulators and energy suppliers interact in relation to alternative energy projects. It analyses the inter-group interactions from the perspective of symbolic interactionism and discusses the aspects that undermine trust, leading to suggestions for improved trust.

    Gastroschisis, a birth defect characterized by herniated fetal abdominal wall, occurs more commonly in infants born to teenage and young mothers. Ischemia of the vascular vitelline vessels is the likely mechanism of pathogenesis. Given that chronic stress and violence against women are risk factors for cardiovascular disease we explored whether these may represent risk factors for gastroschisis, when they occur during pregnancy. A case-control study was conducted, with 15 incident cases of children born with gastroschisis in the Region of Murcia, Spain, from December 2007 to June 2013. Forty concurrent controls were recruited at gestation weeks 20-24 or post-partum. All mothers of cases and controls completed a comprehensive, in-person, 'green sheet' questionnaire on environmental exposures. Mothers of children with gastroschisis were younger, smoked more cigarettes per week relative to controls, were exposed to higher amounts of illegal drugs, and suffered from domestic violence more frequently than the controls. Multivariable logistic regression analysis highlights periconceptional 'gender-related violence' (OR: 16.6, 95% CI 2.7 to 101.7) and younger maternal age (OR 1.1, 95% CI 1.0-1.3). Violence against pregnant women is associated with birth defects, and should be studied in more depth as a cause-effect teratogenic. Psychosocial risk factors, including gender-based violence, are important for insuring the health and safety of the pregnant mother and the fetus.

    Trust is a fundamental concept in many real-world applications such as e-commerce and peer-to-peer networks. In these applications, users can generate local opinions about the counterparts based on direct experiences, and these opinions can then be aggregated to build trust among unknown users. The mechanism to build new trust relationships based on existing ones is referred to as trust inference.

    In general, it seems that both genetic and environmental factors play important roles in the induction of neural tube defects. Lipomyelomeningocele (LipoMMC) is a rather common type of closed neural tube defect, but only limited studies have investigated the potential risk factors of this anomaly. Therefore, the purpose of this case-control study was to investigate the risk factors involved in LipoMMC formation. Various risk factors were evaluated in 35 children between 1 month and 10 years of age with LipoMMC in a hospital-based case-control study. The 2 control arms consisted of 35 children with myelomeningocele (MMC group) and 35 children with congenital anomalies other than central nervous system problems (control group). All groups were matched for age and visited the same hospital. A structured questionnaire was used for the collection of all data, including the mothers' weight and height during pregnancy, education, reproductive history, previous abortions, and socioeconomic status, as well as the parents' consanguinity and family history of the same anomalies. Univariate analysis of the children with LipoMMC compared to the control group showed that the use of periconceptional folic acid supplementation was significantly lower in the MMC and LipoMMC groups compared to the control group. In addition, comparison of the MMC and control groups revealed statistically significant differences regarding the use of folic acid and maternal obesity. In multivariate analysis, use of folic acid in the periconceptional period and during the first trimester was an independent risk factor for LipoMMC and MMC. Furthermore, maternal obesity was a significantly positive risk factor for MMC. The probable risk factors for LipoMMC were investigated in this case-control study. Consumption of folic acid in the periconceptional period and during the first trimester is an independent protective factor against LipoMMC. It seems that larger studies are needed to examine other possible

    The aim of the present study was to examine if certain aspects of a woman's experience of abortion might be associated with the risk of breast cancer. The case-control study was conducted in Kragujevac (Serbia) during the period 2004-2005. The case group (191 women) consisted of patients with newly diagnosed first primary breast cancer, which was histologically confirmed. The control group (191 women), individually matched by age (± 2 years), hospital admittance and place of residence (rural/urban) to the respective cases, was selected from female patients admitted for other diseases. The analysis was restricted to parous women (168 cases and 171 controls). Breast cancer risk was reduced among women who had a history of any abortion (adjusted OR, 0.46; 95% CI, 0.24-0.88). The protective effect was found for both induced abortion (adjusted OR, 0.47; 95% CI, 0.25-0.90) and spontaneous abortion (adjusted OR, 0.31; 95% CI, 0.10-0.98). It seems that these associations did not depend on the number of abortions, age at first abortion, or gestational age at first aborted pregnancy. Our study suggests that even short pregnancies ending in abortion add to the protection against breast cancer.

  4. Trust in automation and meta-cognitive accuracy in NPP operating crews

    International Nuclear Information System (INIS)

    Skraaning Jr, G.; Miberg Skjerve, A. B.

    2006-01-01

    Nuclear power plant operators can over-trust or under-trust automation. Operator trust in automation is said to be mis-calibrated when the level of trust is not corresponding to the actual level of automation reliability. A possible consequence of mis-calibrated trust is degraded meta-cognitive accuracy. Meta-cognitive accuracy is the ability to correctly monitor the effectiveness of ones own performance while engaged in complex tasks. When operators misjudge their own performance, human control actions will be poorly regulated and safety and/or efficiency may suffer. An analysis of simulator data showed that meta-cognitive accuracy and trust in automation were highly correlated for knowledge-based scenarios, but uncorrelated for rule-based scenarios. In the knowledge-based scenarios, the operators overestimated their performance effectiveness under high levels of trust, they underestimated performance under low levels of trust, but showed realistic self-assessment under intermediate levels of trust in automation. The result was interpreted to suggest that trust in automation impact the meta-cognitive accuracy of the operators. (authors)

    To search for an association between tuberculosis and use of biomass stoves found recently in a cross sectional study. In a case-control study based in a chest referral hospital, the cases were 288 patients with active smear-positive or culture-positive tuberculosis, and the controls were 545 patients with ear nose and throat ailments with no evidence of chest disease studied at the same time as the cases. Exposure to present or previous biomass smoke by history of cooking with traditional wood stoves was assessed by positive or negative response. Exposure to biomass smoke was significantly higher in cases than in controls. Crude odds ratios for tuberculosis and biomass smoke exposure were 5.2 (95%CI 3.1-8.9) for current exposure, 3.4 (95%CI 2.4-5.0) for past or present exposure and 1.8 (95%CI 1.1-3.0) for past exposure. The association was observed only for patients living in Metropolitan Mexico City and urban or suburban areas in the center of Mexico providing most cases and controls. For rural areas, the power of the study was low and the origin of the patients heterogeneous. Odds ratio for Mexico City Metropolitan area and the center of Mexico was 2.4 (95%CI 1.04-5.6), adjusted for age, sex, level of education, crowding, smoking, socio-economic level, zone of residence and state of birth. In the same model smoking had an OR of 1.5 (95%CI 1.0-2.3) for tuberculosis. Our results support a causal role of current domestic biomass smoke exposure in tuberculosis.

    Full Text Available Abstract Background Diabetes mellitus type II afflicts at least 2 million people in Iran. Neuropathy is one of the most common complications of diabetes and lowers the patient's quality of life. Since neuropathy often leads to ulceration and amputation, we have tried to elucidate the factors that can affect its progression. Methods In this case-control study, 110 diabetic patients were selected from the Shariati Hospital diabetes clinic. Michigan Neuropathic Diabetic Scoring (MNDS was used to differentiate cases from controls. The diagnosis of neuropathy was confirmed by nerve conduction studies (nerve conduction velocity and electromyography. The multiple factors compared between the two groups included consumption of angiotensin converting enzyme inhibitors (ACEI, blood pressure, serum lipid level, sex, smoking, method of diabetes control and its quality. Results Statistically significant relationships were found between neuropathy and age, gender, quality of diabetes control and duration of disease (P values in the order: 0.04, 0.04, Conclusion In this study, hyperglycemia was the only modifiable risk factor for diabetic neuropathy. Glycemic control reduces the incidence of neuropathy, slows its progression and improves the diabetic patient's quality of life. More attention must be paid to elderly male diabetic patients with poor diabetes control with regard to regular foot examinations and more practical education.

  7. Parkinson Patients' Initial Trust in Avatars: Theory and Evidence.

    Andrija Javor

    Full Text Available Parkinson's disease (PD is a neurodegenerative disease that affects the motor system and cognitive and behavioral functions. Due to these impairments, PD patients also have problems in using the computer. However, using computers and the Internet could help these patients to overcome social isolation and enhance information search. Specifically, avatars (defined as virtual representations of humans are increasingly used in online environments to enhance human-computer interaction by simulating face-to-face interaction. Our laboratory experiment investigated how PD patients behave in a trust game played with human and avatar counterparts, and we compared this behavior to the behavior of age, income, education and gender matched healthy controls. The results of our study show that PD patients trust avatar faces significantly more than human faces. Moreover, there was no significant difference between initial trust of PD patients and healthy controls in avatar faces, while PD patients trusted human faces significantly less than healthy controls. Our data suggests that PD patients' interaction with avatars may constitute an effective way of communication in situations in which trust is required (e.g., a physician recommends intake of medication. We discuss the implications of these results for several areas of human-computer interaction and neurological research.

    Full Text Available Prior pregnancy is known to protect against development of breast cancer. Recent studies have demonstrated that pregnancy has the capacity to establish small numbers of immunologically active fetal-derived cells in the mother, a phenomenon known as fetal microchimerism (FMc. We asked whether presence of FMc, routinely acquired during pregnancy, is a protective factor for breast cancer.DNA extracts from peripheral blood specimens were obtained from a population-based case-control study of risk factors for breast cancer in women 21 to 45 years old. Specimens were tested with quantitative PCR for presence and concentrations of male DNA presumed to derive from prior pregnancies with a male fetus. Odds ratios (OR and 95% confidence intervals (CI were estimated with consideration of multiple established reproductive and environmental risk factors for breast cancer. FMc results were generated on 99 parous women, 54 with primary invasive breast cancer and 45 general population controls. FMc prevalence was 56% (25/45 and 26% (14/54 in controls and cases, respectively. Women harboring FMc were less likely to have had breast cancer (OR = 0.29, 95% CI 0.11-0.83; p = 0.02, adjusting for age, number of children, birth of a son, history of miscarriage, and total DNA tested. In addition, FMc concentrations were higher in controls versus cases (p = 0.01. Median concentrations were 2 (0-78 and 0 (0-374 fetal genomes/10(6 maternal genomes in controls and cases, respectively.Results suggest that the enigma of why some parous women are not afforded protection from breast cancer by pregnancy might in part be explained by differences in FMc. Mechanistic studies of FMc-derived protection against breast cancer are warranted.

    To test the association between diabetes and tuberculosis. It is a case-control study, matched by age and sex. We included 323 new cases of tuberculosis with positive results for bacilloscopy. The controls were 323 respiratory symptomatic patients with negative bacilloscopy, from the same health services, such as: ambulatory cases from three referral hospitals and six basic health units responsible for the notifications of new cases of tuberculosis in Salvador, Bahia. Data collection occurred between 2008 and 2010. The instruments used were structured interview, including clinical data, capillary blood glucose (during fasting or postprandial), and the CAGE questionnaire for screening of abusive consumption of alcohol. Descriptive, exploratory, and multivariate analysis was performed using conditional logistic regression. The average age of the cases was 38.5 (SD = 14.2) years and of the controls, 38.5 (SD = 14.3) years. Among cases and controls, most subjects (61%) were male. In univariate analysis we found association between the occurrence of diabetes and tuberculosis (OR = 2.37; 95%CI 1.04-5.42), which remained statistically significant after adjustment for potential confounders (OR = 3.12; 95%CI 1.12-7.94). The association between diabetes and tuberculosis can hinder the control of tuberculosis, contributing to the maintainance of the disease burden. The situation demands increasing early detection of diabetes among people with tuberculosis, in an attempt to improve disease control strategies. Testar a associação entre diabetes e tuberculose.

  14. Trust and Distrust in E-Commerce

    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.

    Full Text Available The mixed H2/H∞ control problem is studied for systems governed by infinite horizon backward stochastic differential equations (BSDEs with exogenous disturbance signal. A necessary and sufficient condition for the existence of a unique solution to the H2/H∞ control problem is derived. The equivalent feedback solution is also discussed. Contrary to deterministic or stochastic forward case, the feedback solution is no longer feedback of the current state; rather, it is feedback of the entire history of the state.

    We extend the mathematical malaria epidemic model framework of Dembele et al. and use it to ``capture" the 2013 Centers for Disease Control and Prevention (CDC) reported data on the 2011 number of imported malaria cases in the USA. Furthermore, we use our ``fitted" malaria models for the top 20 countries of malaria acquisition by USA residents to study the impact of protecting USA residents from malaria infection when they travel to malaria endemic areas, the impact of protecting residents of malaria endemic regions from mosquito bites and the impact of killing mosquitoes in those endemic areas on the CDC number of imported malaria cases in USA. To significantly reduce the number of imported malaria cases in USA, for each top 20 country of malaria acquisition by USA travelers, we compute the optimal proportion of USA international travelers that must be protected against malaria infection and the optimal proportion of mosquitoes that must be killed.

    We conducted a case-control study of clinically diagnosed Alzheimer's disease (AD) on 170 cases aged 52 to 96 years, and 170 controls matched for age, sex and, where possible, the general practice of origin. Trained lay interviewers naive to the hypotheses and to the clinical status of the elderly person carried out risk-factor interviews with informants. Significant odds ratios were found for 4 variables: a history of either dementia, probable AD, or Down's syndrome in a 1st-degree relative, and underactivity as a behavioral trait in both the recent and more distant past. Previously reported or suggested associations not confirmed by this study include head injury, starvation, thyroid disease, analgesic abuse, antacid use (aluminum exposure), alcohol abuse, smoking, and being left-handed.

    2000-01-01

    sets from the first two tests have been chosen for Test Cases for computational comparisons concentrating on static conditions and cases with harmonically oscillating control surfaces. Several flutter Test Cases from both tests have also been included. Some aerodynamic comparisons with the BACT data have been made using computational fluid dynamics codes at the Navier-Stokes level (and in the accompanying chapter SC). Some mechanical and active control studies have been presented. In this report several Test Cases are selected to illustrate trends for a variety of different conditions with emphasis on transonic flow effects. Cases for static angles of attack, static trailing-edge and upper-surface spoiler deflections are included for a range of conditions near those for the oscillation cases. Cases for trailing-edge control and upper-surface spoiler oscillations for a range of Mach numbers, angle of attack, and static control deflections are included. Cases for all three types of flutter instability are selected. In addition some cases are included for dynamic response measurements during forced oscillations of the controls on the flexible mount. An overview of the model and tests is given, and the standard formulary for these data is listed. Some sample data and sample results of calculations are presented. Only the static pressures and the first harmonic real and imaginary parts of the pressures are included in the data for the Test Cases, but digitized time histories have been archived. The data for the Test Cases are also available as separate electronic files.

    To identify potential risk factors associated with a sudden increase in gastroschisis cases in northern Nevada. Case-control study. Medical centers and a pregnancy care center in Reno, Nevada. Participants (n = 14) were women who gave birth to infants with gastroschisis at either of the 2 medical centers in Reno, Nevada, from April 5, 2007, through April 4, 2008. Controls (n = 57) were selected from the same pregnancy center providing perinatal care to the cases and were matched 4:1 to the case mothers by maternal date of birth within 1 year. Environmental exposures and illnesses during pregnancy. Association of gastroschisis with illnesses, medications, or environmental exposures. Gastroschisis was associated with the use of methamphetamine (odds ratio [OR], 7.15; 95% confidence interval [CI], 1.35-37.99) or any vasoconstrictive recreational drug (methamphetamine, amphetamine, cocaine, ecstasy) (OR, 4.46; 95% CI, 1.21-16.44) before pregnancy. When we limited self-reported illnesses to those occurring during the first trimester of pregnancy, chest colds (OR, 16.77; 95% CI, 1.88-150.27) and sore throats (OR, 12.72; 95% CI, 1.32-122.52) were associated with gastroschisis. These findings add strength to the hypothesis that use of methamphetamine and related drugs is a risk factor for gastroschisis and raise questions about the risks associated with infections.

    Self trust. The nuclear community and particularly nuclear regulators overreact to accidents, this has been the case with the three NPP major accidents. Lowering admissible radiation levels, for example, conveys the wrong message to politicians and the general public, and contributes to enhance mistrust towards nuclear. Industry as well as regulators should mature and act with self respect, since the scientific bases of regulation are very solid and should be trusted. Lessons learned should be seriously pursued in spite of the 'uneven playing field'. Obviously safety continues as the main priority, but paranoid reactions from the nuclear professionals could destroy the future of nuclear power. (author)

  10. A question of scent: lavender aroma promotes interpersonal trust

    Directory of Open Access Journals (Sweden)

    Roberta eSellaro

    2015-01-01

    Full Text Available A previous study has shown that the degree of trust into others might be biased by inducing either a more inclusive or exclusive cognitive-control mode. Here, we investigated whether the degree of interpersonal trust can be biased by environmental factors, such as odors, that are likely to impact cognitive-control states. Arousing olfactory fragrances (e.g., peppermint are supposed to induce a more exclusive, and calming olfactory fragrances (e.g., lavender a more inclusive state. Participants 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, while being exposed to either peppermint or lavender aroma. All participants played the role of trustor. As expected, participants transferred significantly more money to the alleged trustee in the lavender as compared to the peppermint and no aroma conditions. This observation might have various serious implications for a broad range of situations in which interpersonal trust is an essential element, such as cooperation (e.g., mixed-motives situations, bargaining and negotiation, consumer behavior, and group performance.

    Zhao, Jing; Ha, Sejin; Widdows, Richard

    2013-09-01

    This study investigates consumers' use of online health communities (OHCs) for healthcare from a relationship building perspective based on the commitment-trust theory of relationships. The study proposes that perspective taking, empathic concern, self-efficacy, and network density affect the development of both cognitive and affective trust, which together determine OHC members' membership continuance intention (MCI) and knowledge contribution. Data collected from eight existing OHCs (N=255) were utilized to test the hypothesized model. Results show that perspective taking and self-efficacy can increase cognitive trust and affective trust, respectively. Network density contributes to cognitive and affective trust. Both cognitive trust and affective trust influence MCI, while only affective trust impacts members' knowledge contribution behaviors.

  15. Applying Machine Trust Models to Forensic Investigations

    Science.gov (United States)

    Wojcik, Marika; Venter, Hein; Eloff, Jan; Olivier, Martin

    Digital forensics involves the identification, preservation, analysis and presentation of electronic evidence for use in legal proceedings. In the presence of contradictory evidence, forensic investigators need a means to determine which evidence can be trusted. This is particularly true in a trust model environment where computerised agents may make trust-based decisions that influence interactions within the system. This paper focuses on the analysis of evidence in trust-based environments and the determination of the degree to which evidence can be trusted. The trust model proposed in this work may be implemented in a tool for conducting trust-based forensic investigations. The model takes into account the trust environment and parameters that influence interactions in a computer network being investigated. Also, it allows for crimes to be reenacted to create more substantial evidentiary proof.

    Full Text Available Software-defined networks (SDNs have become a mechanism to separate the control plane and the data plane in the communication in networks. SDNs involve several challenges around their security and their confidentiality. Ideally, SDNs should incorporate autonomous and adaptive systems for controlling the routing to be able to isolate network resources that may be malfunctioning or whose security has been compromised with malware. The current work introduces a novel agent-based framework that simulates SDN isolation protocols by means of trust and reputation models. This way, SDN programmers may estimate the repercussions of certain isolation protocols based on trust models before actually deploying the protocol into the network.

    2017-11-01

    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.

    Trust is an essential ingredient in all working relationships. When trust breaks down, conflicts may arise and teams may stop working in harmony. 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. All four of these pillars need to be in...

  9. TRUST - A FACTOR OF PRODUCTION

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available The economic activity is more and more influenced by the condition and the evolution of some immaterial and non-financial elements which exist in a firm or a country. One of these elements - information - has unanimously been accepted as the 4th production factor. In this paper I try to demonstrate that trust too, has to be accepted as a production factor. Especially as it fulfils the fundamental conditions for this to happen : it is infinitly divisible and homogeneous and, thus, its marginal product can be calculated. In nowadays world, characterized by the apparently unstoppable expansion of the cruel individualism and of market fundamentalism, which have undermined the trust in the success of private initiative, producers increasingly need community, need another mode of involvement of the state in economy and they need another way of relating to each other. The costs resulting from the diminishing of trust have become so significant that their transformation into income is necessary, if we succeed in basing ourselves on trust in the economic process.

    Background Leptospira can be found in soil. However, it is unclear whether occupational exposure to soil may represent a risk for Leptospira infection in humans. Therefore, we sought to determine the association of Leptospira IgG seroprevalence with the occupation of gardener, and to determine the epidemiological characteristics of gardeners associated with Leptospira exposure. Methods We performed a case-control study in 168 gardeners and 168 age- and gender-matched control subjects without gardening occupation in Durango City, Mexico. The seroprevalence of anti-Leptospira IgG antibodies in cases and controls was determined using an enzyme immunoassay. Bivariate and multivariate analyses were used to assess the association of Leptospira exposure and the characteristics of the gardeners. Results Anti-Leptospira IgG antibodies were found in 10 (6%) of 168 gardeners and in 15 (8.9%) of 168 control subjects (odds ratio (OR): 0.64; 95% confidence interval (CI): 0.28 - 1.48; P = 0.40). Multivariate analysis showed that Leptospira seropositivity was positively associated with female gender (OR: 5.82; 95% CI: 1.11 - 30.46; P = 0.03), and negatively associated with eating while working (OR: 0.21; 95% CI: 0.05 - 0.87; P = 0.03). In addition, multivariate analysis showed that high anti-Leptospira levels were associated with consumption of boar meat (OR: 28.00; 95% CI: 1.20 - 648.80; P = 0.03). Conclusions This is the first case-control study of Leptospira exposure in gardeners. Results do not support an association of Leptospira exposure with the occupation of gardener. However, further studies to confirm the lack of this association are needed. The potential role of consumption of boar meat in Leptospira infection deserves further investigation. PMID:26668679

  11. Trust in Leadership for Sustaining Innovations: How Leaders Enact on Showing Trustworthiness

    2014-11-01

    Full Text Available In the environment of continuous change today, trust is needed more in most organizations but is enacted less. This paper discusses trust in leadership. Trust is the essence of leadership forming a foundation for functioning relationships and co-operation. Trust is intangible asset, a managerial skill, and an influencing power for leaders. Leadership by trust emphasizes trustful behavior towards employees. It can be defined as an interactive way of leading organizations for effectiveness and profitability. In this paper, we suggest that, it is trustworthiness in leader behavior that matters. Showing trustworthiness by competence, integrity, benevolence, and credibility makes a difference in daily leadership work and sustaining innovations. This paper focuses on how leaders enact on trust by showing trustworthiness to subordinates. Real life case examples are presented and their implications are discussed. In conclusion, leadership by trust matters in building innovative work environment. As to untrustworthy leader behavior, it is worth noting that building and sustaining trust is reciprocal in nature. A practical implication for leaders is that the development of an awareness of trustworthiness and skills for demonstrating it should be a top priority in the current business environment, which demands strong interaction, cooperation, and communication abilities.

    2014-01-01

    When a hospitalized older patient falls or develops delirium, there are significant consequences for the patient and the health care system. Assessments of inattention and altered consciousness, markers for delirium, were analyzed to determine if they were also associated with falls. This retrospective case-control study from a regional tertiary Veterans Affairs referral center identified falls and delirium risk factors from quality databases from 2010 to 2012. Older fallers with complete delirium risk assessments prior to falling were identified. As a control, non-fallers were matched at a 3:1 ratio. Admission risk factors that were compared in fallers and non-fallers included altered consciousness, cognitive performance, attention, sensory deficits, and dehydration. Odds ratio (OR) was reported (95% confidence interval [CI]). After identifying 67 fallers, the control population (n=201) was matched on age (74.4±9.8 years) and ward (83.6% medical; 16.4% intensive care unit). Inattention as assessed by the Months of the Year Backward test was more common in fallers (67.2% versus 50.8%, OR=2.0; 95% CI: 1.1-3.7). Fallers tended to have altered consciousness prior to falling (28.4% versus 12.4%, OR=2.8; 95% CI: 1.3-5.8). In this case-control study, alterations in consciousness and inattention, assessed prior to falling, were more common in patients who fell. Brief assessments of consciousness and attention should be considered for inclusion in fall prediction.

    2002-02-01

    This study examined general public's trust in national government and electric power companies in terms of nuclear power policies, and that in the government in terms of defense policies. A questionnaire was distributed to a sample of 560 Kobe citizens, and a total of 409 complete it. Covariance structure analysis was performed to test hypotheses of the present study. Results suggested that the more demanding of the government and corporations, the lower the person's trust. How well the person understood the difficulty of the work involved hardly affected his/her demand and trust in all three actors of the two issues. Results also indicated that the person who perceived the government to be under pressure to appear trustworthy tended to have lower trust in them, that Yamagishi's general trust (1998) did not influence the trust in the cases, and that awareness of popular political empowerment had a negative impact on the trust in the government.

    2003-09-01

    We begin with the following definitions: Definition: A trusted volume is the computing machinery (including communication lines) within which data is assumed to be physically protected from an adversary. A trusted volume provides both integrity and privacy. Definition: Program integrity consists of the protection necessary to enable the detection of changes in the bits comprising a program as specified by the developer, for the entire time that the program is outside a trusted volume. For ease of discussion we consider program integrity to be the aggregation of two elements: instruction integrity (detection of changes in the bits within an instruction or block of instructions), and sequence integrity (detection of changes in the locations of instructions within a program). Definition: Faithful Execution (FE) is a type of software protection that begins when the software leaves the control of the developer and ends within the trusted volume of a target processor. That is, FE provides program integrity, even while the program is in execution. (As we will show below, FE schemes are a function of trusted volume size.) FE is a necessary quality for computing. Without it we cannot trust computations. In the early days of computing FE came for free since the software never left a trusted volume. At that time the execution environment was the same as the development environment. In some circles that environment was referred to as a ''closed shop:'' all of the software that was used there was developed there. When an organization bought a large computer from a vendor the organization would run its own operating system on that computer, use only its own editors, only its own compilers, only its own debuggers, and so on. However, with the continuing maturity of computing technology, FE becomes increasingly difficult to achieve

  18. Public trust and better communication is still needed

    Korean nuclear regulatory agency (KINS) has recently changed its 'safety philosophy': The final goal of nuclear safety should he achievement of psychological and emotional security of people rather than simple attainment of engineering safety targets. This significant progress is not widely known for public. But, its new attitude was confirmed when a nuclear reactor for research purpose, which was located in a metropolitan city, leaked a small amount of radioactive materials in 2005. The agency focused on the fact itself that radioactive materials were released into environment although its amount of radioactivity was negligible from engineering perspective. Does this mean that 'science-technology centrism' which has widely pervaded nuclear circle begin to collapse from the regulatory agency? There has been certain degree of advancement in openness of information, increasing transparency, communication efforts toward public and local. people. However, it should he noted that regulatory activity has not attained enough trust from public. Four points are pointed out for regulatory agency to get further people's trust. First, nuclear agency's institutional independence is still uncertain. The Ministry of Science and Technology, which is in charge of nuclear safety by controlling KINS, at the same time promotes nuclear industry by managing nuclear R and D activities. Cultural aspects should also be noted. People tend to regard regulatory agency as 'friends' of nuclear. Second, regulatory activities are passive and not preventive in many cases. It is needed to make people convince that the regulatory agency defend their interest first when it competes with the interest of industry. Third, communication with public is lacking. Even transparent procedure and openness of information may result in limiting public access if its content and meaning are not fully communicated. Fourth, knowing more about media is needed. Understanding news production processes may contribute to

    Madagascar, as other malaria endemic countries, depends mainly on international funding for the implementation of malaria control interventions (MCI). As these funds no longer increase, policy makers need to know whether these MCI actually provide the expected protection. This study aimed at measuring the effectiveness of MCI deployed in all transmission patterns of Madagascar in 2012-2013 against the occurrence of clinical malaria cases. From September 2012 to August 2013, patients consulting for non-complicated malaria in 31 sentinel health centres (SHC) were asked to answer a short questionnaire about long-lasting insecticidal nets (LLIN) use, indoor residual spraying (IRS) in the household and intermittent preventive treatment of pregnant women (IPTp) intake. Controls were healthy all-ages individuals sampled from a concurrent cross-sectional survey conducted in areas surrounding the SHC. Cases and controls were retained in the database if they were resident of the same communes. The association between Plasmodium infection and exposure to MCI was calculated by multivariate multilevel models, and the protective effectiveness (PE) of an intervention was defined as 1 minus the odds ratio of this association. Data about 841 cases (out of 6760 cases observed in SHC) and 8284 controls was collected. The regular use of LLIN provided a significant 51 % PE (95 % CI [16-71]) in multivariate analysis, excluding in one transmission pattern where PE was -11 % (95 % CI [-251 to 65]) in univariate analysis. The PE of IRS was 51 % (95 % CI [31-65]), and the PE of exposure to both regular use of LLIN and IRS was 72 % (95 % CI [28-89]) in multivariate analyses. Vector control interventions avoided yearly over 100,000 clinical cases of malaria in Madagascar. The maternal PE of IPTp was 73 %. In Madagascar, LLIN and IRS had good PE against clinical malaria. These results may apply to other countries with similar transmission profiles, but such case-control surveys could be

  7. The Case for Intelligent Propulsion Control for Fast Engine Response

    Litt, Jonathan S.; Frederick, Dean K.; Guo, Ten-Huei

    2009-01-01

    Damaged aircraft have occasionally had to rely solely on thrust to maneuver as a consequence of losing hydraulic power needed to operate flight control surfaces. The lack of successful landings in these cases inspired research into more effective methods of utilizing propulsion-only control. That research demonstrated that one of the major contributors to the difficulty in landing is the slow response of the engines as compared to using traditional flight control. To address this, research is being conducted into ways of making the engine more responsive under emergency conditions. This can be achieved by relaxing controller limits, adjusting schedules, and/or redesigning the regulators to increase bandwidth. Any of these methods can enable faster response at the potential expense of engine life and increased likelihood of stall. However, an example sensitivity analysis revealed a complex interaction of the limits and the difficulty in predicting the way to achieve the fastest response. The sensitivity analysis was performed on a realistic engine model, and demonstrated that significantly faster engine response can be achieved compared to standard Bill of Material control. However, the example indicates the need for an intelligent approach to controller limit adjustment in order for the potential to be fulfilled.

    Full Text Available ABSTRACT OBJECTIVE To determine the sociodemographic, behavioral, and health care factors related to the occurrence of syphilis in women treated at public maternity hospitals. METHODS This is a case-control study (239 cases and 322 controls with women admitted to seven maternity hospitals in the municipality of Recife, Brazil, from July 2013 to July 2014. Eligible women were recruited after the result of the VDRL (Venereal Disease Research Laboratory under any titration. The selection of cases and controls was based on the result of the serology for syphilis using ELISA (enzyme-linked immunosorbent assay. The independent variables were grouped into: sociodemographic, behavioral, clinical and obstetric history, and health care in prenatal care and maternity hospital. Information was obtained by interview, during hospitalization, with the application of a questionnaire. Odds ratios and 95% confidence intervals were estimated using logistic regression to identify the predicting factors of the variable to be explained. RESULTS The logistic regression analysis identified as determinant factors for gestational syphilis: education level of incomplete basic education or illiterate (OR = 2.02, lack of access to telephone (OR = 2.4, catholic religion (OR = 1.70 , four or more pregnancies (OR = 2.2, three or more sexual partners in the last year (OR = 3.1, use of illicit drugs before the age of 18 (OR = 3.0, and use of illicit drugs by the current partner (OR = 1.7. Only one to three prenatal appointments (OR = 3.5 and a previous history of sexually transmitted infection (OR = 9.7 were also identified as determinant factors. CONCLUSIONS Sociodemographic, behavioral, and health care factors are associated with the occurrence of syphilis in women and should be taken into account in the elaboration of universal strategies aimed at the prevention and control of syphilis, but with a focus on situations of greater vulnerability.

    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 current study describes the development of the Attorney-Client Trust Scale (ACTS), a measure designed to assess a client's trust in his or her attorney. A sample of 307 male inmates completed the ACTS and provided information about their most recent case and attorney. Low ACTS scores were associated with having a court-appointed attorney, going to trial, and receiving a lengthy prison sentence. High ACTS scores were related to satisfaction with sentences and attorneys. In addition, findings suggest that perceptions about attorneys' interpersonal skills were as important as perceptions about legal skills in forming opinions about overall lawyering ability. It is recommended that attorneys employ a well rounded assortment of interpersonal skills to foster their clients' trust and to make better use of the limited amount of time they have to spend with clients.

    Full Text Available OBJECTIVE: To identify risk factors associated with infant mortality and, more specifically, with neonatal mortality. METHODS: A case-control study was carried out in the municipality of Caxias do Sul, Southern Brazil. Characteristics of prenatal care and causes of mortality were assessed for all live births in the 2001-2002 period with a completed live-birth certificate and whose mothers lived in the municipality. Cases were defined as all deaths within the first year of life. As controls, there were selected the two children born immediately after each case in the same hospital, who were of the same sex, and did not die within their first year of life. Multivariate analysis was performed using conditional logistic regression. RESULTS: There was a reduction in infant mortality, the greatest reduction was observed in the post-neonatal period. The variables gestational age (<36 weeks, birth weight (<2,500 g, and 5-minute Apgar (<6 remained in the final model of the multivariate analysis, after adjustment. CONCLUSIONS: Perinatal conditions comprise almost the totality of neonatal deaths, and the majority of deaths occur at delivery. The challenge for reducing infant mortality rate in the city is to reduce the mortality by perinatal conditions in the neonatal period.

    Full Text Available Colorectal cancer is one of the most common cancers worldwide. The role of the female sex hormones in the etiology of the disease is very intriguing. Reproductive factors are surrogate measure of lifetime exposition to the sex hormones. Purpose: Our aim is to investigate the association between the reproductive factors and colorectal carcinoma risk. Materials and methods: We include 234 Bulgarian women in our study – 117 cases with colorectal cancer and the same number of healthy controls. Cases are divided into three groups according to the localization of the tumor. We conduct case-control study, using questionnaires about reproductive factors. We use the following statistical methods – descriptive, variational analysis, binary logistic regression. Results: We observed that only the age at menopause is associated with colorectal cancer risk, and this factor has strongest protective effect in the proximal colon (95% CI - 0,051-0,781, OR – 0,200, p – 0,021. Conclusion: Analyzing our data we observed that among Bulgarian women the only reproductive factor that show association with the risk of colorectal cancer is the age at menopause.

    Full Text Available Abstract Introduction People with schizophrenia are at increased risk of developing metabolic disturbances. This risk may be further exacerbated by the use of antipsychotic agents. Research is still ongoing to determine the metabolic impact of antipsychotics on glucose regulation. In this case report we review some of the possible mechanisms of action of antipsychotic medication on glucose regulation. Case presentation We present the case of a 50-year-old man diagnosed with paranoid schizophrenia who developed type 2 diabetes mellitus whilst on treatment with second generation antipsychotics (SGA. His diabetes was controlled by a combination of antidiabetic drugs that were associated with his psychotropic treatment. Due to deterioration in his mental state, the patient was admitted on two occasions to a psychiatric unit during which his prescribed medication (olanzapine and risperidone was discontinued and changed to aripiprazole. On both occasions, the patient suffered hypoglycaemic episodes and his antidiabetic treatment had to be adjusted accordingly. The patient did not require any antidiabetic treatment whilst on aripiprazole during the follow up period. Conclusion Clinicians face regular dilemmas in trying to find the right balance between achieving control over a patient's mental illness and reducing any adverse effects associated with the prescribed medication. In patients receiving concomitant antidiabetic therapy, caution should be exercised when changing from one SGA to another. Whilst more longitudinal data are required, a trial of alternative SGAs, including aripiprazole in those developing type 2 diabetes and impaired glucose tolerance may be a worthwhile therapeutic option.

    Three experiments tested the effects of ego depletion on economic decision making. Participants completed a task either requiring self-control or not. Then participants learned about the trust game, in which senders are given an initial allocation of $10 to split between themselves and another person, the receiver. The receiver receives triple the amount given and can send any, all, or none of the tripled money back to the sender. Participants were assigned the role of the sender and decided how to split the initial allocation. Giving less money, and therefore not trusting the receiver, is the safe, less risky response. Participants who had exerted self-control and were depleted gave the receiver less money than those in the non-depletion condition (Experiment 1). This effect was replicated and moderated in two additional experiments. Depletion again led to lower amounts given (less trust), but primarily among participants who were told they would never meet the receiver (Experiment 2) or who were given no information about how similar they were to the receiver (Experiment 3). Amounts given did not differ for depleted and non-depleted participants who either expected to meet the receiver (Experiment 2) or were led to believe that they were very similar to the receiver (Experiment 3). Decreased trust among depleted participants was strongest among neurotics. These results imply that self-control facilitates behavioral trust, especially when no other cues signal decreased social risk in trusting, such as if an actual or possible relationship with the receiver were suggested.

    2017-02-01

    Full Text Available The aim of this paper is to shed more light on the significant effect that leadership self-efficacy and shared leadership have on organizational performance. The purpose of this study is to contribute to the research on shared leadership that is still in its early stages. Trust, as a component of social capital, is considered the essential criteria for an emotionally aware leader. Trust enables individuals to channel their energy on those aspects of work for which they have real passion. Emotions, whether positive or negative, stimulate and steer organizational performance and behavior. Humor can reduce absenteeism; improve levels of effort, health and energy, all of which influence the levels of performance. The case study methodology focused on a profit-oriented Information Technology SME. A questionnaire was distributed to ascertain how leadership self-efficacy might influence shared leadership and affect organizational performance. The study entails the presupposition that those managers who have regard for the self-efficacy leadership attributes cluster will have a higher probability of improving both perceived and actual employee performance. The results of this study seem to demonstrate that emphasis is placed on the problem-solving attributes of leadership self-efficacy. This will result in a positive impact on the organizational performance as a whole. This paper is of added value for scholars and organizations in the knowledge economy.

  18. Interpersonal trust and quality-of-life: a cross-sectional study in Japan.

    Yasuharu Tokuda

    Full Text Available BACKGROUND: There is growing interest in psychosocial factors with positive attitudes, such as interpersonal trust, as determinants for Quality-of-life (QOL or subjective well-being. Despite their longevity, Japanese people report a relatively poor subjective well-being, as well as lower interpersonal trust. Our aim in this study was to evaluate the possible association between interpersonal trust and QOL among Japanese people. METHODOLOGY AND PRINCIPAL FINDINGS: Based on the cross-sectional data for Japanese adults (2008, we analyzed the relationship between interpersonal trust and each of four domains of the WHOQOL-BREF. Interpersonal trust was assessed using three scales for trust in people, in human fairness and in human nature. In a total of 1000 participants (mean age: 45 years; 49% women, greater trust was recognized among women (vs. men, those aged 60-69 (vs. 20-29, or the high-income group (vs. low-income. Each of three trust scales was positively correlated with all domains of QOL. Multiple linear-regression models were constructed for each of QOL and the principal component score of the trust scales, adjusted for age, gender, area size of residence, income, education, and occupation. For all QOL domains, interpersonal trust was significantly and positively associated with better QOL with p<0.001 for all four domains including physical, psychological, social, and environmental QOL. Other factors associated with QOL included gender, age class, area size of residence, and income. Education and occupation were not associated with QOL. CONCLUSIONS AND SIGNIFICANCE: Greater interpersonal trust is strongly associated with a better QOL among Japanese adults. If a causal relationship is demonstrated in a controlled interventional study, social and political measures should be advocated to increase interpersonal trust for achieving better QOL.

    Full Text Available Background: Sexual dysfunction in breast cancer patients is considered as a common and distressing problem. Considering the increasing number of breast cancer survivors living for longer periods of time with the disease and the importance of their quality of life, we conducted the present study to compare the sexual functioning in breast cancer patients with their healthy counterparts.Methods: In this case-control study, breast cancer patients who completed their treatment protocol and were followed up for at least six months were included. The controls were healthy women with normal clinical breast examinations. All subjects filled-in the Persian version of Female Sexual Function Index questionnaire.Results: A total of 165 subjects including 71 breast cancer patients and 94 healthy women were studied. The frequency of sexual dysfunction in cases and controls was 52.6% and 47.4%, respectively (P = 0.09. There were no significant differences between the two groups regarding domain scores, except for vaginal lubrication (P = 0.045. Logistic regression analysis indicated that significant determinants of sexual dysfunction in breast cancer group was patients' age (OR = 4.0, 95%CI: 1.3 – 11.5, P = 0.01 and age of the spouse (OR= 9.8, 95% CI: 1.8-51.9, P= 0.007, while in controls, only emotional relationship with the husband was the significant predictive factor (OR = 6.3, 95%CI: 1.9 – 20.5, P = 0.002.Conclusions: Our findings indicated that sexual dysfunction is prevalent in Iranian women regardless of their physical health status. The frequency of vaginal dryness in breast cancer patients was significantly higher than controls. Age of the patient and the spouse (>40 were the only significant predictors of sexual dysfunction among women with breast cancer. Preventive strategies, sexual education and access to effective treatment should be planned in supportive care of breast cancer patients.

    Full Text Available Objectives: To investigate vestibular function, foot sensation, postural control and functional abilities, and to evaluate whether these variables are associated with fall-related wrist fracture. Methods: A case-control study was conducted with 98 subjects, age range 50–75 years, who had sustained a fall-related wrist fracture. Forty-eight sex-, age- and physical activity-matched individuals, with no previous history of wrist fracture, served as controls. Measurements included: head-shake test (HST, tuning fork, biothesiometer, Semmes-Weinstein monofilaments (MF, Sensory Organization Test (SOT, Five-Times-Sit-to-Stand Test (FTSTS, 10-m walk test (10MWT, Activities-specific Balance Confidence (ABC, and the Dizziness Handicap Inventory (DHI scales. Logistic regression models were used to determine associations of variables with a fall-related wrist fracture. Results: Vestibular asymmetry was apparent in 82% of wrist fracture subjects and 63% of controls (p = 0.012. Plantar pressure sensation (p <0.001, SOT composite scores (p < 0.001, 10MWT (p <0.001, FTSTS (p <0.001, ABC (p <0.001 and DHI (p <0.005 were significantly poorer among cases than controls. A positive HST (odds ratio (OR 5.424; p = 0.008 and monofilament sensation (OR 3.886; p = 0.014 showed the strongest associations with having a fall-related wrist fracture. Conclusion: Asymmetrical vestibular function and reduced plantar pressure sensation are associated with fall-related wrist fractures among the ageing population. These factors are potential targets for future interventions.

    All automations must, at some point in their lifecycle, interface with one or more humans. Whether operators, end-users, or bystanders, human responses can determine the perceived utility and acceptance of an automation. It has been long believed that human trust is a primary determinant of human-automation interactions and further presumed that calibrating trust can lead to appropriate choices regarding automation use. However, attempts to improve joint system performance by calibrating trust have not yet provided a generalizable solution. To address this, we identified several factors limiting the direct integration of trust, or metrics thereof, into an active mitigation strategy. The present paper outlines our approach to addressing this important issue, its conceptual underpinnings, and practical challenges encountered in execution. Among the most critical outcomes has been a shift in focus from trust to basic interaction behaviors and their antecedent decisions. This change in focus inspired the development of a testbed and paradigm that was deployed in two experiments of human interactions with driving automation that were executed in an immersive, full-motion simulation environment. Moreover, by integrating a behavior and physiology-based predictor within a novel consequence-based control system, we demonstrated that it is possible to anticipate particular interaction behaviors and influence humans towards more optimal choices about automation use in real time. Importantly, this research provides a fertile foundation for the development and integration of advanced, wearable technologies for sensing and inferring critical state variables for better integration of human elements into otherwise fully autonomous systems.

  2. Trust Management Considerations For the Cooperative Infrastructure Defense Framework: Trust Relationships, Evidence, and Decisions

    Energy Technology Data Exchange (ETDEWEB)

    Maiden, Wendy M.

    2009-12-01

    Cooperative Infrastructure Defense (CID) is a hierarchical, agent-based, adaptive, cyber-security framework designed to collaboratively protect multiple enclaves or organizations participating in a complex infrastructure. CID employs a swarm of lightweight, mobile agents called Sensors designed to roam hosts throughout a security enclave to find indications of anomalies and report them to host-based Sentinels. The Sensors’ findings become pieces of a larger puzzle, which the Sentinel puts together to determine the problem and respond per policy as given by the enclave-level Sergeant agent. Horizontally across multiple enclaves and vertically within each enclave, authentication and access control technologies are necessary but insufficient authorization mechanisms to ensure that CID agents continue to fulfill their roles in a trustworthy manner. Trust management fills the gap, providing mechanisms to detect malicious agents and offering more robust mechanisms for authorization. This paper identifies the trust relationships throughout the CID hierarchy, the types of trust evidence that could be gathered, and the actions that the CID system could take if an entity is determined to be untrustworthy.

    Controlled human infection model (CHIM) studies have pivotal importance in vaccine development, being useful for proof of concept, pathogenesis, down-selection and immunogenicity studies.  To date, however, they have seldom been carried out in low and middle income countries (LMIC), which is where the greatest burden of vaccine preventable illness is found.  This workshop discussed the benefits and barriers to CHIM studies in Malawi.  Benefits include improved vaccine effectiveness and host country capacity development in clinical, laboratory and governance domains.  Barriers include acceptability, safety and regulatory issues. The report suggests a framework by which ethical, laboratory, scientific and governance issues may be addressed by investigators considering or planning CHIM in LMIC.

    Full Text Available Interpersonal trust among team members is an important phenomenon influencing working relationships and performance outcomes. However, there is a lack of empirical studies investigating the development of trust with respect to behavioural and environmental factors in a group of strangers. This exploratory, mixed method study investigated the development of two-dimensional interpersonal trust (affective and cognitive and team cohesion in a newly formed temporary team of novice adults during a seven-day sail training programme. A descriptive longitudinal case study approach was adopted in the current study. Seven crew members completed the standardised psychometric questionnaires and were interviewed during the voyage. Results suggested that the development of trust occurs over three phases; 1 initial perception of shared identity, 2 early trust and 3 two dimensional trust comprising cognitive and affective dimensions. Distinct antecedents for the development of trust at each stage were identified and the importance of the competence-oriented subcomponent of cognitive trust within this challenging environmental context was highlighted. Exploratory interpretation suggests some overlap in the antecedents of interpersonal trust and team cohesion. However, further longitudinal research must examine this relationship and establish corroborative evidence for the model of trust. This research can impact on practitioners leading programmes to better understand how trust can develop over time, and offers a pragmatic approach to investigations in real world contexts.

    The prevalence of hypothyroidism in SLE patients varies considerably and early reports were mainly based on small cohorts. To investigate the association between SLE and hypothyroidism. Patients with SLE were compared with age and sex-matched controls regarding the proportion of hypothyroidism in a case-control study. Chi-square and t-tests were used for univariate analysis and a logistic regression model was used for multivariate analysis. The study was performed utilizing the medical database of Clalit Health Services. The study included 5018 patients with SLE and 25,090 age and sex-matched controls. The proportion of hypothyroidism in patients with SLE was increased compared with the prevalence in controls (15.58% and 5.75%, respectively, Phypothyroidism (odds ratio 2.644, 95% confidence interval 2.405-2.908). Patients with SLE have a greater proportion of hypothyroidism than matched controls. Therefore, physicians treating patients with SLE should be aware of the possibility of thyroid dysfunction.

    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.

    2010-11-01

    To determine whether older paternal age increases the risk of fathering a pregnancy with Patau (trisomy 13), Edwards (trisomy 18), Klinefelter (XXY) or XYY syndrome. Case-control: cases with each of these syndromes were matched to four controls with Down syndrome from within the same congenital anomaly register and with maternal age within 6 months. Data from 22 EUROCAT congenital anomaly registers in 12 European countries. Diagnoses with observed or (for terminations) predicted year of birth from 1980 to 2005, comprising live births, fetal deaths with gestational age ≥ 20 weeks and terminations after prenatal diagnosis of the anomaly. Data include 374 cases of Patau syndrome, 929 of Edwards syndrome, 295 of Klinefelter syndrome, 28 of XYY syndrome and 5627 controls with Down syndrome. Odds ratio (OR) associated with a 10-year increase in paternal age for each anomaly was estimated using conditional logistic regression. Results were adjusted to take account of the estimated association of paternal age with Down syndrome (1.11; 95% CI 1.01 to 1.23). The OR for Patau syndrome was 1.10 (95% CI 0.83 to 1.45); for Edwards syndrome, 1.15 (0.96 to 1.38); for Klinefelter syndrome, 1.35 (1.02 to 1.79); and for XYY syndrome, 1.99 (0.75 to 5.26). There was a statistically significant increase in the odds of Klinefelter syndrome with increasing paternal age. The larger positive associations of Klinefelter and XYY syndromes with paternal age compared with Patau and Edwards syndromes are consistent with the greater percentage of these sex chromosome anomalies being of paternal origin.

  13. Rumor Spreading Model with Trust Mechanism in Complex Social Networks

    Wang, Ya-Qi; Yang, Xiao-Yuan; Han, Yi-Liang; Wang, Xu-An

    2013-04-01

    In this paper, to study rumor spreading, we propose a novel susceptible-infected-removed (SIR) model by introducing the trust mechanism. We derive mean-field equations that describe the dynamics of the SIR model on homogeneous networks and inhomogeneous networks. Then a steady-state analysis is conducted to investigate the critical threshold and the final size of the rumor spreading. We show that the introduction of trust mechanism reduces the final rumor size and the velocity of rumor spreading, but increases the critical thresholds on both networks. Moreover, the trust mechanism not only greatly reduces the maximum rumor influence, but also postpones the rumor terminal time, which provides us with more time to take measures to control the rumor spreading. The theoretical results are confirmed by sufficient numerical simulations.

    Full Text Available Abstract Background Prader-Willi syndrome (PWS is a complex neurodevelopmental genetic disorder with hypothalamic dysfunction, early morbid obesity with hyperphagia, and specific psychiatric phenotypes including cognitive and behavioural problems, particularly disruptive behaviours and frequent temper outbursts that preclude socialization. A deficit in oxytocin (OT-producing neurons of the hypothalamic paraventricular nucleus has been reported in these patients. Methods In a double-blind, randomised, placebo-controlled study, 24 adult patients with PWS received a single intranasal administration of 24 IU of OT or placebo and were tested 45 min later on social skills. Behaviours were carefully monitored and scored using an in-house grid as follows: over the two days before drug administration, on the half-day following administration, and over the subsequent two days. All patients were in a dedicated PWS centre with more than ten years of experience. Patients are regularly admitted to this controlled environment. Results Patients with PWS who received a single intranasal administration of OT displayed significantly increased trust in others (P = 0.02 and decreased sadness tendencies (P = 0.02 with less disruptive behaviour (P = 0.03 in the two days following administration than did patients who received placebo. In the half-day following administration, we observed a trend towards less conflict with others (p = 0.07 in the OT group compared with the placebo group. Scores in tests assessing social skills were not significantly different between the two groups. Conclusions This study needs to be reproduced and adapted. It nevertheless opens new perspectives for patients with PWS and perhaps other syndromes with behavioural disturbances and obesity. Trial registration number ClinicalTrials.gov: NCT01038570

    Gigliette, Linda Marie

    The purpose of this research was to investigate the effect of a trust-building technique called "positive-framing" (Lemov, 2010, p. 204) on the level of student-teacher trust and students' science academic achievement. The existing literature was reviewed under the constructs of trust, types of trust, trust-building strategies, and student academic achievement. The identified problem is a lack of research into the effect of trust from the high school student perspective and the effect of trust on student academic achievement in science. In addition, there is no empirical evidence to support the effectiveness of the "positive-framing" (Lemov, 2010, p. 204) trust-building intervention. The study involved a volunteer, convenience sample of 9th-grade science students at one high school in Northern California (N=240). The study employed a quasi-experimental, pretest, posttest non-equivalent control group design to examine the level of student trust in the teacher, using the "Student trust in faculty scale" (Forsyth, Adams, & Hoy, 2011, p. 180), and the students' academic achievement, according to the Integrated Process Skills Test II (Okey, Wise, & Burns, 1982). The independent variable was the "positive-framing" (Lemov, 2010, p. 204) trust-building intervention; the two dependent variables were the level of student-teacher trust and student academic achievement. The composite data from the "Student trust in faculty scale" and the academic achievement test were evaluated by a multivariate analysis of covariance (MANCOVA). Results of this study indicated that the null hypothesis was accepted. The "positive-framing" (Lemov, 2010, p. 204) trust-building intervention did not have a significant effect on either the student-teacher trust level or academic achievement in science.

    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...... conclude that while trust facilitates welfare state policies that may reduce net inequality, this decrease in inequality does not increase trust....

The charts included were those belonging to zero to 14 year old children with injuries, poisoning, and II-III degrees of malnutrition. Four child-abuse criteria were established: physical, sexual, non organic malnutrition and mixed (physical and non organic malnutrition). Two control groups were defined. Different patterns were observed between accidental and non accidental injuries, malnutrition and poisoning among the case and the control groups. The study provides useful information for the integral diagnosis of child abuse in hospitalized children.

    This paper presents a generic business case for implementation of technology that supports Control Room Modernization (CRM). The analysis presented in two forms; 1) a standalone technology upgrade, and 2) a technology upgrade that is built upon and incremental to a prior business case created for Mobile Work Packages (MWP). The business case contends that advanced communication and networking and analytical technologies will allow NPP to conduct control room operations with improved focus by reducing human factors and redundant manpower, and therefore operate with fewer errors. While some labor savings can be harvested in terms of overtime, the majority of savings are demonstrated as reduced time to take the plant off line and bring back on line in support of outages. The benefits are quantified to a rough order of magnitude that provides directional guidance to NPPs that are interested in developing a similar business case. This business case focuses on modernization of the operator control room and does not consider a complete overhaul and modernization of a plants instrument and control systems. While operators may be considering such an investment at their plants, the sizable capital investment required is not likely supported by a cost/benefit analysis alone. More likely, it is driven by obsolescence and reliability issues, and requires consideration of mechanical condition of plant systems, capital depreciation, financing, relicensing and overall viability of the plant asset over a 20-year horizon in a competitive market. Prior studies [REF] have indicated that such a modernization of plant I&C systems, alone or as part of a larger modernization effort, can yield very significant reductions in O&M costs. However, the depth of research and analysis required to develop a meaningful business case for a plant modernization effort is well beyond the scope of this study. While CRM as considered in this study can be easily integrated as part of grander plant

    Study Objectives: To investigate the restorative quality of sleep and daytime functioning in sleepwalking adult patients in comparison with controls. Design: Prospective case-control study. Setting: Data were collected at the Sleep Disorders Center, Hôpital-Gui-de Chauliac, Montpellier, France between June 2007 and January 2011. Participants: There were 140 adult sleepwalkers (100 (median age 30 y, 55% male) in whom primary SW was diagnosed) who underwent 1 night of video polysomnography. All patients participated in a standardized clinical interview and completed a battery of questionnaires to assess clinical characteristics of parasomnia, daytime sleepiness, fatigue, insomnia, depressive and anxiety symptoms, and health-related quality of life. Results were compared with those of 100 sex- and age-matched normal controls. Interventions: N/A. Measurements and Results: Of the sleepwalkers, 22.3% presented with daily episodes and 43.5% presented with weekly episodes. Median age at sleepwalking onset was 9 y. Familial history of sleepwalking was reported in 56.6% of sleepwalkers and violent sleep related behaviors in 57.9%, including injuries requiring medical care for at least one episode in 17%. Significant associations were found between sleepwalking and daytime sleepiness, fatigue, insomnia, depressive and anxiety symptoms, and altered quality of life. Early-onset sleepwalkers had higher frequency of violent behaviors and injuries. Sleepwalkers with violent behaviors had higher frequency of sleep terrors and triggering factors, with greater alteration in health-related quality of life. Conclusion: Adult sleepwalking is a potentially serious condition that may induce violent behaviors, self-injury or injury to bed partners, sleep disruption, excessive daytime sleepiness, fatigue, and psychological distress, all of which affect health-related quality of life.

    What makes money essential for the functioning of modern society? Through an experiment, we present evidence for the existence of a relevant behavioral dimension in addition to the standard theoretical arguments. Subjects faced repeated opportunities to help an anonymous counterpart who changed over time. Cooperation required trusting that help given to a stranger today would be returned by a stranger in the future. Cooperation levels declined when going from small to large groups of strangers, even if monitoring and payoffs from cooperation were invariant to group size. We then introduced intrinsically worthless tokens. Tokens endogenously became money: subjects took to reward help with a token and to demand a token in exchange for help. Subjects trusted that strangers would return help for a token. Cooperation levels remained stable as the groups grew larger. In all conditions, full cooperation was possible through a social norm of decentralized enforcement, without using tokens. This turned out to be especially demanding in large groups. Lack of trust among strangers thus made money behaviorally essential. To explain these results, we developed an evolutionary model. When behavior in society is heterogeneous, cooperation collapses without tokens. In contrast, the use of tokens makes cooperation evolutionarily stable.

    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.

    To assess factors associated with impulse control disorders (ICDs) in Parkinson disease (PD) using a multicenter case--control design. Patients enrolled in the DOMINION study, a multicenter study assessing the cross-sectional frequency of ICDs in PD, were eligible to participate in the case--control study. PD patients with and without an ICD (n = 282 each) (compulsive gambling, buying, sexual behavior, and eating) were matched individually on age, gender, and dopamine agonist treatment. Subjects were assessed with a comprehensive neurological, psychiatric, and cognitive assessment battery. ICD patients reported more functional impairment (p compulsive symptoms (p cognitive impairments, including affective and anxiety symptoms, as well as elevated obsessionality, novelty seeking, and impulsivity. These results highlight the importance of assessing multiple mental health domains in individuals with PD and ICDs, and suggest possible pathophysiological mechanisms and risk indicators for these disorders.

    This study examines the distribution and correlates of a special class of property crimes, crimes of trust, using longitudinal and cross sectional self-report data from a national sample. We begin by defining crimes of trust and consider their conceptual relationship to "conventional" property crimes, which we here characterize as crimes of stealth, and to white collar crimes, which are defined in terms of the social status of the perpetrators. Crimes of trust are here defined as property crimes that typically involve deliberate contact with the victim or, where there is more than one victim, with at least one or more victims, in which there is typically more of a focus on concealing the fact that a crime has been committed than on concealing the identity of the perpetrator (as is the case in crimes of stealth), without regard to the socioeconomic status of the perpetrator (thus including but not limited to white collar crimes). The focus here is on crimes of trust committed by individuals (as opposed to corporate crime). We first examine their distribution by sociodemographic characteristics, then examine the correlation of crimes of trust with other types of illegal behavior, using data from the National Youth Survey Family Study, including (1) longitudinal self-report data from a nationally representative panel of individuals who were 11-18 years old in 1976-77 and who were followed through early middle age (ages 36-44) in 2002-2003, plus (2) cross-sectional data on these individuals plus their parents, spouses, and children age 11 and older in 2002-2003 (total age range 11-88). The results suggest that crimes of trust have a different age-crime curve from conventional crimes, and that they are not as strongly correlated with problem substance use, gender, and other socioeconomic indicators as conventional crimes.

    Full Text Available Objective: The World health organization (WHO has accepted Keith Edward scoring system for the diagnosis of childhood tuberculosis (TB. In the present study, we evaluated this scoring system. Methods and Results: We included 53 children with confirmed TB involving different organs, admitted in NB Medical College, during two years period as cases; and 50 randomly selected, age, sex, and organ matched confirmed non-TB cases as controls. We noticed 15.1% false negative and 22% false positive results in our study, and the scoring system had 84.9% sensitivity, 78% specificity, and 80.36% positive predictive value. Likelihood ratio positive (LR+ was 3.86, likelihood ratio negative (LR- was 0.19, and overall agreement was 81.55%. We observed that Keith Edward scoring system was less effective in children suffering from non-TB chronic diseases (false positive rate: 45.5%. We found no significant difference in nutritional status between study and control groups (P = 0.65. We noticed that more than 15-mm indurations for tuberculin test were specific for TB in children. Conclusion: We concluded that Keith Edward scoring system is good for public health purpose, but there is a scope for improvement, and further study is required for this purpose.

    This study was conducted to determine the correlation between preeclampsia and depression. Participants in this study included 156 cases with preeclampsia and 156 controls without any history of preeclampsia who were all newly admitted to antepartum wards, emergency room wards, and labor and delivery wards of the study hospitals (Valieasr, Shariatti, Mirza Koochak Khan, Shahid Akbar Abadi, Baharloo and Arash). They consented and completed a questionnaire on demographic characteristics, obstetric, delivery and infant information and Patient Health Questionnaire (PHQ-9) to assess their depression status. Data were analyzed through independent t test, Mann-Whitney U test, Chi-squared test, Fisher's exact test and multiple regression by SPSS and STATA. Moderate to severe depression was found in 31.2% of the cases and 24.8% of the controls. Women with no depression in comparison with women with mild depression had a 1.81-fold (95% CI 1.05-3.14; P = 0.03) increased risk of preeclampsia, while moderate to severe depression correlated with a 2.52-fold increase (95% CI 1.05-6.02; P = 0.03) after adjustment of the probable confounding variables. With regard to the high prevalence of moderate to severe depression and its association with preeclampsia, our findings support and suggest efforts for screening depression among pregnant women and appropriate educational studies for mental and psychological problems during pregnancy.

    Full Text Available Trachoma is widely considered a disease of poverty. Although there are many epidemiological studies linking trachoma to factors normally associated with poverty, formal quantitative data linking trachoma to household economic poverty within endemic communities is very limited.Two hundred people with trachomatous trichiasis were recruited through community-based screening in Amhara Region, Ethiopia. These were individually matched by age and gender to 200 controls without trichiasis, selected randomly from the same sub-village as the case. Household economic poverty was measured through (a A broad set of asset-based wealth indicators and relative household economic poverty determined by principal component analysis (PCA, (b Self-rated wealth, and (c Peer-rated wealth. Activity participation data were collected using a modified 'Stylised Activity List' developed for the World Bank's Living Standards Measurement Survey. Trichiasis cases were more likely to belong to poorer households by all measures: asset-based analysis (OR = 2.79; 95%CI: 2.06-3.78; p<0.0001, self-rated wealth (OR, 4.41, 95%CI, 2.75-7.07; p<0.0001 and peer-rated wealth (OR, 8.22, 95% CI, 4.59-14.72; p<0.0001. Cases had less access to latrines (57% v 76.5%, p = <0.0001 and higher person-to-room density (4.0 v 3.31; P = 0.0204 than the controls. Compared to controls, cases were significantly less likely to participate in economically productive activities regardless of visual impairment and other health problems, more likely to report difficulty in performing activities and more likely to receive assistance in performing productive activities.This study demonstrated a strong association between trachomatous trichiasis and relative poverty, suggesting a bidirectional causative relationship possibly may exist between poverty and trachoma. Implementation of the full SAFE strategy in the context of general improvements might lead to a virtuous cycle of improving health and wealth

    The study identified factors predisposing to non-albicans candidemia with special interest to prior antimicrobial treatment. A retrospective, case-case-control study was performed at the University Hospital of Heraklion, Greece, from November 2007 through September 2011 including adult patients. The study had three groups. The first included 58 patients with non-albicans candidemia, the second 48 with C. albicans candidemia, while the third (control) 104 without candidemia. Each of the two candidemia groups was compared with the control using multivariate logistic regression model. The mean (SD) age of the non-albicans, the albicans and the control patients was 67 (12), 67 (18) and 59 (19) years, respectively. The most common non-albicans Candida spp. isolated were C. parapsilosis in 19 patients (33%), C. glabrata in 17 (29%) and C. tropicalis in 15 (26%). Independent risk factors for non-albicans candidemia were prior treatment with quinolones (p candidemia were prior treatment with quinolones (p candidemia groups. The study reveals the role of antimicrobial exposure as a risk factor for candidemia caused by different species. Prior treatment with b-lactam-b-lactamase inhibitors was associated with non-albicans, while with carbapenems with C. albicans candidemia. Prior use of quinolones was associated with candidemia in general.

    Full Text Available At present we can observe the increasing role of cooperation among companies all around the world. Cooperation includes many forms, such as alliances, joint ventures, networks, clusters, outsourcing and others. Trust is one of the most important factors of success of any cooperation activity, because it can lower transaction costs, increase productivity and innovativeness, facilitate inter-organizational relationships and resolve conflicts. Therefore the paper discusses the basic problems of trust in alliance networks. The text consists of theoretical deliberations devoted to alliance networks and trust. The practical case of the company from machine industry that formed a portfolio of alliances based on trust is also an important part of the text. The conclusion of the paper is that portfolio of alliances based on trust is worth pursuing.

    Migrants constitute an interesting case concerning the question of how trust in welfare state institutions can emerge, as one can study their newly built relationships with such institutions in a distinct way. The Danish welfare state can be considered a ‘high trust’ context in terms of social...... and institutional trust. With the help of a multi-dimensional theoretical concept this paper provides an analysis of qualitative interviews with migrants on how institutional trust in the welfare state can emerge. Among other things, it finds that a perceived experience of distributive justice is of crucial...... importance for building trust and that strong trust in the systemic checks and balances of the welfare state can ‘override’ negative experiences at its access points, that is, welfare state professionals....

  18. Developing patient rapport, trust and therapeutic relationships.

    2017-08-09

    Rapport is established at the first meeting between the patient and nurse, and is developed throughout the therapeutic relationship. However, challenges can arise during this process. Initially, nurses can establish trust with the patient through the questions they ask, however, as care progresses, the nurse will be required to demonstrate a commitment to maintaining the patient's psychological well-being. When the therapeutic relationship ends, the nurse should assist the patient to assess progress and plan the next stage of recovery. This article provides three reflective exercises using case study examples to demonstrate how rapport is developed and sustained. Evidence is provided to identify why challenges arise in the therapeutic relationship and how the nurse can ensure they provide care that the patient regards as genuine.

    Full Text Available Objective: Psoriasis is a chronic, relapsing and disfiguring dermatological disorder with a significant effect on occupational, social, and other areas of functioning. Psychological stress has been known to have a significant role in the onset and exacerbation of this illness. To study the prevalence of psychiatric morbidity in psoriasis and the influence of specified demographic, psychological, social and illness-related variables. Methods: The study was carried out at a tertiary care hospital in a large urban setup. In this case–control study, 100 cases of psoriasis were studied in comparison with healthy controls who were matched for sociodemographic profile. The participants were given a sociodemographic questionnaire, clinical profile sheet, and psoriasis area and severity index (PASI. General Health Questionnaire-12 (GHQ-12 was used to screen for psychological distress, and subsequently, Hospital Anxiety and Depression Scale for screening for depression and anxiety and World Health Organization Quality of Life-BREF scale for assessing the quality of life (QOL were administered. The results obtained were analyzed for evaluating the psychiatric morbidity and its various correlates. Appropriate statistical analysis was done using SPSS 21. Results: Using GHQ-12 cutoff score (≥3 for psychological distress, the overall prevalence of psychological distress was significantly more in cases of in comparison to healthy controls with an odds ratio of 8.54 (95% confidence interval 3.16–23.07, P < 0.0001. Statistical analysis showed a statistically significant correlation of educational status with QOL and severity of skin lesions (PASI with anxiety level. Severe skin lesions, more so on visible body parts were associated more commonly with psychological distress. Conclusions: All patients of psoriasis should be educated about the nature of the illness and screened for psychological distress. Dermatologists and family members should be educated to

    Full Text Available This research investigates into interpersonal trust and workplace outcomes in organizations within social exchange perspective. Current study is building upon the theoretical underpinnings of trust studies that pose trust as a psychological state and a social glue. Current research develops a theoretical model of interpersonal trust presuming that different trust objects -namely peers and senior managementhave unique and direct effects on global workplace outcomes: Affective commitment, turnover intention, and job satisfaction. The data was collected via convenience sampling and data consists of 134 professionals working in Turkey. Structural Equation Modeling (SEM using Partial Least Squares (PLS is employed to test our model. Findings suggest that trust in peers and trust in senior management translate into higher affective commitment. Results indicate a positive association between job satisfaction and trust in senior management. Turnover intention however, did not significantly associate with any of the trust variables suggesting the difference between economic exchange and social exchange, which involves reciprocal behaviors. Simultaneous investigation of two trust objects in organizations as well as inclusion of variety of contextual factors bring rigor to the scope of the research and the explanations of workplace outcomes.
