In the last decade, algorithms for reputation systems are been widely developed in order to achieve correct ratings for products, services, companies, digital contents and people. We start from a comprehensive mathematical model for Collaborative Reputation Systems (CRSes), present in the literature and formally defined as a recurrence relation that generates a sequence of trust matrices, from which the reputation of the items and the raters can be derived. Even though this model can be applied to several scenarios, the focus of this work is related to its application in a real case, that is a cultural event scenario. More in detail, in cultural heritage environment, the data collected in an event represent the basic knowledge to be inferred. The main idea is to correctly use the available technology and data to give a reliable rate (reputation) for both visitors and artworks. These rates will be very useful to classify the visiting style of the visitors and to fix the artworks that have most attracted visitors.

Pricing Strategy in Online Retailing Marketplaces of Homogeneous Goods: Should High Reputation Seller Charge More?

NASA Astrophysics Data System (ADS)

Liu, Yuewen; Wei, Kwok Kee; Chen, Huaping

There are two conflicting streams of research findings on pricing strategy: one is high reputation sellers should charge price premium, while the other is high reputation sellers should charge relatively low price. Motivated by this confliction, this study examines pricing strategy in online retailing marketplace of homogeneous goods. We conduct an empirical study using data collected from a dominant online retailing marketplace in China. Our research results indicate that, in online retailing marketplace of homogeneous goods, high reputation sellers should charge relatively low price, because the consumers of high reputation sellers are more price sensitive than the consumers of low reputation sellers.

New journals for publishing medical case reports.

PubMed

Akers, Katherine G

2016-04-01

Because they do not rank highly in the hierarchy of evidence and are not frequently cited, case reports describing the clinical circumstances of single patients are seldom published by medical journals. However, many clinicians argue that case reports have significant educational value, advance medical knowledge, and complement evidence-based medicine. Over the last several years, a vast number (∼160) of new peer-reviewed journals have emerged that focus on publishing case reports. These journals are typically open access and have relatively high acceptance rates. However, approximately half of the publishers of case reports journals engage in questionable or "predatory" publishing practices. Authors of case reports may benefit from greater awareness of these new publication venues as well as an ability to discriminate between reputable and non-reputable journal publishers.

Gambling scores for earthquake predictions and forecasts

NASA Astrophysics Data System (ADS)

Zhuang, Jiancang

2010-04-01

This paper presents a new method, namely the gambling score, for scoring the performance earthquake forecasts or predictions. Unlike most other scoring procedures that require a regular scheme of forecast and treat each earthquake equally, regardless their magnitude, this new scoring method compensates the risk that the forecaster has taken. Starting with a certain number of reputation points, once a forecaster makes a prediction or forecast, he is assumed to have betted some points of his reputation. The reference model, which plays the role of the house, determines how many reputation points the forecaster can gain if he succeeds, according to a fair rule, and also takes away the reputation points betted by the forecaster if he loses. This method is also extended to the continuous case of point process models, where the reputation points betted by the forecaster become a continuous mass on the space-time-magnitude range of interest. We also calculate the upper bound of the gambling score when the true model is a renewal process, the stress release model or the ETAS model and when the reference model is the Poisson model.

An investigation into alleged 'hauntings'.

PubMed

Wiseman, Richard; Watt, Caroline; Stevens, Paul; Greening, Emma; O'Keeffe, Ciarán

2003-05-01

In cases of alleged hauntings, a large number of seemingly trustworthy witnesses consistently report experiencing unusual phenomena (e.g. apparitions, sudden changes in temperature, a strong sense of presence) in certain locations. The two studies reported here explored the psychological mechanisms that underlie this apparent evidence of 'ghostly' activity. The experiments took place at two locations that have a considerable reputation for being haunted-Hampton Court Palace (Surrey, England) and the South Bridge Vaults (Edinburgh, Scotland). Both studies involved participants walking around these locations and reporting where they experienced unusual phenomena. Results revealed significantly more reports of unusual experiences in areas that had a reputation for being haunted. This effect was not related to participants' prior knowledge about the reputation of these areas. However, the location of participants' experiences correlated significantly with various environmental factors, including, for example, the variance of local magnetic fields and lighting levels. These findings strongly suggest that alleged hauntings may not necessarily represent evidence for 'ghostly' activity, but could be, at least in part, the result of people responding to 'normal' factors in their surroundings.

Cooperative behaviour and prosocial reputation dynamics in a Dominican village.

Macfarlan, Shane J; Quinlan, Robert; Remiker, Mark

2013-06-22

Prosocial reputations play an important role, from the evolution of language to Internet transactions; however, questions remain about their behavioural correlates and dynamics. Formal models assume prosocial reputations correlate with the number of cooperative acts one performs; however, if reputations flow through information networks, then the number of individuals one assists may be a better proxy. Formal models demonstrate indirect experience must track behaviour with the same fidelity as direct experience for reputations to become viable; however, research on corporate reputations suggests performance change does not always affect reputation change. Debate exists over the cognitive mechanisms employed for assessing reputation dynamics. Image scoring suggests reputations fluctuate relative to the number of times one fails to assist others in need, while standing strategy claims reputations fluctuate relative to the number of times one fails to assist others in good standing. This study examines the behavioural correlates of prosocial reputations and their dynamics over a 20-month period in an Afro-Caribbean village. Analyses suggest prosocial reputations: (i) are correlated with the number of individuals one assists in economic production, not the number of cooperative acts; (ii) track cooperative behaviour, but are anchored across time; and (iii) are captured neither by image scoring nor standing strategy-type mechanisms.

The Inevitability of Infidelity: Sexual Reputation, Social Geographies, and Marital HIV Risk in Rural Mexico

Hirsch, Jennifer S.; Meneses, Sergio; Thompson, Brenda; Negroni, Mirka; Pelcastre, Blanca; del Rio, Carlos

2007-01-01

Marriage presents the single greatest risk for HIV infection among women in rural Mexico. We drew on 6 months of participant observation, 20 marital case studies, 37 key informant interviews, and archival research to explore the factors that shape HIV risk among married women in one of the country’s rural communities. We found that culturally constructed notions of reputation in this community lead to sexual behavior designed to minimize men’s social risk (threats to one’s social status or relationships), rather than viral risk and that men’s desire for companionate intimacy may actually increase women’s risk for HIV infection. We also describe the intertwining of reputation-based sexual identities with structurally patterned sexual geographies (i.e. the social spaces that shape sexual behavior). We propose that, because of the structural nature of men’s extramarital sexual behavior, intervention development should concentrate on sexual geographies and risky spaces rather than risky behaviors or identities.

Influence of energy alternatives and carbon emissions on an institution's green reputation.

Komarek, Timothy M; Lupi, Frank; Kaplowitz, Michael D; Thorp, Laurie

2013-10-15

Institutions' reputation for being environmentally friendly or 'green' can come from many sources. This paper examines how the attributes of alternative energy management plans impact an institutions' 'green' reputation by focusing on the interaction between 'external' and 'internal' influences. Some 'external' influences on environmental reputation we studied include the institution's mix of fuels, energy conservation effort, carbon emissions targets, investment time-frame, and program cost. The 'internal' influences on institutions' green reputation we examined include altruism (respondents' concern for the welfare of others) and environmentalism (respondents' concern for the environment). Using a stated-preference conjoint survey, we empirically examine how attributes of alternative energy management plans influence a large, research university's 'green' reputation. Our results show that constituents benefit from their institution's green reputation and that the energy management choices of the institution can significantly influence its perceived green reputation. Furthermore, integrating internal and external influences on reputation can create more informative models and better decision-making. Copyright © 2013 Elsevier Ltd. All rights reserved.

Athanasiou, Georgia; Lymberopoulos, Dimitrios

2016-08-01

Absence of trust foundations may outweigh benefits of ubiquitous and personalized mental healthcare supervision provided within a Ubiquitous Healthcare environment (UH). Trust is composed by patient's Personal Interaction Experience (PIE) and social entourage accumulated PIE, i.e. Reputation (R). In this paper, a cloud-based Reputation mechanism is proposed. Since PIE is the elementary trust information source, also an Updating mechanism of PIE, is introduced, in this paper. Cloud materialization of combined mechanisms provides adaptability to UH Providers' dynamic behavior, facilitates detection of milking behaviors and complex malicious attacks while meets the challenge of limited accuracy in case of data sparseness. The effectiveness of the proposed mechanisms is verified via simulation in MATLAB.

In the shade of a forest status, reputation, and ambiguity in an online microcredit market.

PubMed

Kuwabara, Ko; Anthony, Denise; Horne, Christine

2017-05-01

Scholars have long recognized status and reputation as pervasive forces reproducing comparative advantage in social and economic systems. Yet, due in part to methodological challenges, relatively few studies have examined how status and reputation interact. We use data from an online market for peer-to-peer lending to study independent and joint effects of status and reputation on borrowers' success at obtaining loans. First, we find a positive main effect of status, even when reputational signals are reliable and abundant. Second, we find that status matters the most for borrowers with moderate (rather than high or low) reputations, suggesting a curvilinear effect of status x reputation on loans. These results support the idea that status matters not only under conditions of too little information that creates information asymmetry, as typically assumed, but also under conditions of abundant information and too many choices that creates ambiguity about how to evaluate candidates.

Abstract Accurate species identification is fundamental to biodiversity science, but the natural history skills required for this are neglected in formal education at all levels. In this paper we describe how the web application ispotnature.org and its sister site ispot.org.za (collectively, “iSpot”) are helping to solve this problem by combining learning technology with crowdsourcing to connect beginners with experts. Over 94% of observations submitted to iSpot receive a determination. External checking of a sample of 3,287 iSpot records verified > 92% of them. To mid 2014, iSpot crowdsourced the identification of 30,000 taxa (>80% at species level) in > 390,000 observations with a global community numbering > 42,000 registered participants. More than half the observations on ispotnature.org were named within an hour of submission. iSpot uses a unique, 9-dimensional reputation system to motivate and reward participants and to verify determinations. Taxon-specific reputation points are earned when a participant proposes an identification that achieves agreement from other participants, weighted by the agreers’ own reputation scores for the taxon. This system is able to discriminate effectively between competing determinations when two or more are proposed for the same observation. In 57% of such cases the reputation system improved the accuracy of the determination, while in the remainder it either improved precision (e.g. by adding a species name to a genus) or revealed false precision, for example where a determination to species level was not supported by the available evidence. We propose that the success of iSpot arises from the structure of its social network that efficiently connects beginners and experts, overcoming the social as well as geographic barriers that normally separate the two.

Situational and dispositional determinants of intentional deceiving.

Does opportunity make the thief or are people dispositionally prone to deceive? The interaction between personality and the circumstances surrounding deception is crucial to understand what promotes dishonesty in our society. Due to its inherent spontaneity and sociality, deceptive behaviour may be hardly reproducible in experimental settings. We developed a novel paradigm in the form of an interactive game where participants can choose whether to lie to another person in situations of loss vs. gain, and of no-reputation-risk vs. reputation-risk linked to the disclosure of their deceptive behaviour to others. Thus, our ecological paradigm allowed subjects to spontaneously decide when to lie and face the challenge of deceiving others. In the case of loss, participants lied to reverse the outcome in their favour. Deception was lower in the reputation-risk condition where personality traits concerning social interactions also played an important role. The results suggest that deception is definitely promoted by unfavourable events, and that maintaining one's own reputation encourages honesty, particularly in socially inclined individuals.

Reputation-Based Investment Helps to Optimize Group Behaviors in Spatial Lattice Networks.

Encouraging cooperation among selfish individuals is crucial in many real-world systems, where individuals' collective behaviors can be analyzed using evolutionary public goods game. Along this line, extensive studies have shown that reputation is an effective mechanism to investigate the evolution of cooperation. In most existing studies, participating individuals in a public goods game are assumed to contribute unconditionally into the public pool, or they can choose partners based on a common reputation standard (e.g., preferences or characters). However, to assign one reputation standard for all individuals is impractical in many real-world deployment. In this paper, we introduce a reputation tolerance mechanism that allows an individual to select its potential partners and decide whether or not to contribute an investment to the public pool based on its tolerance to other individuals' reputation. Specifically, an individual takes part in a public goods game only if the number of participants with higher reputation exceeds the value of its tolerance. Moreover, in this paper, an individual's reputation can increase or decrease in a bounded interval based on its historical behaviors. We explore the principle that how the reputation tolerance and conditional investment mechanisms can affect the evolution of cooperation in spatial lattice networks. Our simulation results demonstrate that a larger tolerance value can achieve an environment that promote the cooperation of participants.

Young children with a positive reputation to maintain are less likely to cheat.

The present study examined whether having a positive reputation to maintain makes young children less likely to cheat. Cheating was assessed through a temptation resistance paradigm in which participants were instructed not to cheat in a guessing game. Across three studies (total N = 361), preschool-aged participants were randomly assigned to either a reputation condition, in which an experimenter told them that she had learned of their positive reputation from classmates, or to a control condition in which they received no such information. By age 5, children in the reputation condition cheated less often than those in the control condition even though nobody was watching and choosing not to cheat conflicted with their personal interest. These findings are the first to show that informing children that they have a positive reputation to maintain can influence their moral behavior. © 2015 John Wiley & Sons Ltd.

Indirect Reciprocity, Resource Sharing, and Environmental Risk: Evidence from Field Experiments in Siberia

PubMed Central

Howe, E. Lance; Murphy, James J.; Gerkey, Drew; West, Colin Thor

2016-01-01

Integrating information from existing research, qualitative ethnographic interviews, and participant observation, we designed a field experiment that introduces idiosyncratic environmental risk and a voluntary sharing decision into a standard public goods game. Conducted with subsistence resource users in rural villages on the Kamchatka Peninsula in Northeast Siberia, we find evidence consistent with a model of indirect reciprocity and local social norms of helping the needy. When participants are allowed to develop reputations in the experiments, as is the case in most small-scale societies, we find that sharing is increasingly directed toward individuals experiencing hardship, good reputations increase aid, and the pooling of resources through voluntary sharing becomes more effective. We also find high levels of voluntary sharing without a strong commitment device; however, this form of cooperation does not increase contributions to the public good. Our results are consistent with previous experiments and theoretical models, suggesting strategic risks tied to rewards, punishments, and reputations are important. However, unlike studies that focus solely on strategic risks, we find the effects of rewards, punishments, and reputations are altered by the presence of environmental factors. Unexpected changes in resource abundance increase interdependence and may alter the costs and benefits of cooperation, relative to defection. We suggest environmental factors that increase interdependence are critically important to consider when developing and testing theories of cooperation PMID:27442434

2003-01-01

The health industry has acquired a reputation as lagging in the use of IT. This reputation is usually based upon the relatively narrow measure of comparative IT expenditure, often examined as a proportion of total revenue. This study has been undertaken to assess health's use of IT using a broader frame of reference. The health industry was compared to the banking industry, on the basis that the banking industry is widely perceived as a leading IT user. The research confirmed that in these two 'knowledge' industries, health is slower to adopt IT with an apparent lower maturity level. This was the case across a range of best practice management, procedural and cultural topics as well as in the level of resources applied to IT.

Minigames capturing the essence of Public Goods experiments show that even in the absence of rationality assumptions, both punishment and reward will fail to bring about prosocial behavior. This result holds in particular for the well-known Ultimatum Game, which emerges as a special case. But reputation can induce fairness and cooperation in populations adapting through learning or imitation. Indeed, the inclusion of reputation effects in the corresponding dynamical models leads to the evolution of economically productive behavior, with agents contributing to the public good and either punishing those who do not or rewarding those who do. Reward and punishment correspond to two types of bifurcation with intriguing complementarity. The analysis suggests that reputation is essential for fostering social behavior among selfish agents, and that it is considerably more effective with punishment than with reward.

Human cooperation based on punishment reputation.

PubMed

dos Santos, Miguel; Rankin, Daniel J; Wedekind, Claus

2013-08-01

The threat of punishment usually promotes cooperation. However, punishing itself is costly, rare in nonhuman animals, and humans who punish often finish with low payoffs in economic experiments. The evolution of punishment has therefore been unclear. Recent theoretical developments suggest that punishment has evolved in the context of reputation games. We tested this idea in a simple helping game with observers and with punishment and punishment reputation (experimentally controlling for other possible reputational effects). We show that punishers fully compensate their costs as they receive help more often. The more likely defection is punished within a group, the higher the level of within-group cooperation. These beneficial effects perish if the punishment reputation is removed. We conclude that reputation is key to the evolution of punishment. © 2013 The Author(s).

Clustering recommendations to compute agent reputation

NASA Astrophysics Data System (ADS)

Bedi, Punam; Kaur, Harmeet

2005-03-01

Traditional centralized approaches to security are difficult to apply to multi-agent systems which are used nowadays in e-commerce applications. Developing a notion of trust that is based on the reputation of an agent can provide a softer notion of security that is sufficient for many multi-agent applications. Our paper proposes a mechanism for computing reputation of the trustee agent for use by the trustier agent. The trustier agent computes the reputation based on its own experience as well as the experience the peer agents have with the trustee agents. The trustier agents intentionally interact with the peer agents to get their experience information in the form of recommendations. We have also considered the case of unintentional encounters between the referee agents and the trustee agent, which can be directly between them or indirectly through a set of interacting agents. The clustering is done to filter off the noise in the recommendations in the form of outliers. The trustier agent clusters the recommendations received from referee agents on the basis of the distances between recommendations using the hierarchical agglomerative method. The dendogram hence obtained is cut at the required similarity level which restricts the maximum distance between any two recommendations within a cluster. The cluster with maximum number of elements denotes the views of the majority of recommenders. The center of this cluster represents the reputation of the trustee agent which can be computed using c-means algorithm.

Popularity Breeds Contempt: The Evolution of Reputational Dislike Relations and Friendships in High School.

Fujimoto, Kayo; Snijders, Tom A B; Valente, Thomas W

2017-01-01

In this study, we examined the dynamics of the perception of "dislike" ties (reputational dislike) among adolescents within the contexts of friendship, perceived popularity, substance use, and Facebook use. Survey data were collected from a longitudinal sample of 238 adolescents from the 11th and 12th grades in one California high school. We estimated stochastic actor-based network dynamic models, using reports of reputational dislike, friendships, and perceived popularity, to identify factors associated with the maintenance and generation reputational dislike ties. The results showed that high-status adolescents and more frequent Facebook users tended to become perceived as or stay disliked by their peers over time. There was a tendency for friendships to promote the creation and maintenance of reputational disliking but not vice versa. Adolescents tended to perceive others as disliked when their friends also perceived them as disliked. There was no evidence that either cigarette smoking or drinking alcohol affected reputational dislike dynamics. This study highlights the important role that the hierarchical peer system, online peer context, and friendships play in driving information diffusion of negative peer relations among adolescents.

Reputation strength as a determinant of faculty employment: a test of the step-down thesis among clinical psychology doctoral programs.

This study tested the folkloristic belief that doctoral degree recipients who pursue academic careers typically wind up at institutions ranked lower in prestige than the institutions at which they trained (the step-down thesis). We used a database of faculty members in 150 clinical psychology doctoral programs accredited by the American Psychological Association, and compared each faculty member's training institution with the current employing institution on three distinct reputation ranking systems: The Center (University of Florida, Gainesville) for overall university reputation, the National Research Council (Washington, DC) for doctoral degree department reputation, and the news magazine, U.S. News and World Report ranking for clinical psychology training program reputation. Although support for the step-down thesis was found across all three ranking systems, a disproportionately large number of professors were also observed to move laterally in terms of their employing institution's reputation.

The Sznajd model with limited persuasion: competition between high-reputation and hesitant agents

Crokidakis, Nuno; Murilo Castro de Oliveira, Paulo

2011-11-01

In this work we study a modified version of the two-dimensional Sznajd sociophysics model. In particular, we consider the effects of agents' reputations in the persuasion rules. In other words, a high-reputation group with a common opinion may convince its neighbors with probability p, which induces an increase of the group's reputation. On the other hand, there is always a probability q = 1 - p of the neighbors keeping their opinions, which induces a decrease of the group's reputation. These rules describe a competition between groups with high-reputation and hesitant agents, which makes the full-consensus states (with all spins pointing in one direction) more difficult to reach. As consequences, the usual phase transition does not occur for p < pc ~ 0.69 and the system presents realistic democracy-like situations, where the majority of spins are aligned in a certain direction, for a wide range of parameters.

Manley, A J; Greenlees, I A; Smith, M J; Batten, J; Birch, P D J

2014-04-01

The present study examined the impact of reputation information on athletes' behavioral responses to coaches within a naturalistic, field-based setting. Using a between-group design, male soccer players (n = 35) were assigned to one of three experimental conditions (i.e., experienced reputation, inexperienced reputation, no reputation) prior to taking part in a coaching session delivered by an unknown coach. Participants' behaviors indicative of attention to coach instruction, effort and persistence, and willingness to participate in demonstrations were video recorded throughout the coaching session. Multivariate analyses of variance revealed that participants in the experienced reputation condition exhibited significantly greater attention to coach instruction, and greater effort and persistence during free practice than participants in the inexperienced reputation condition. Results related to participants' willingness to participate in demonstrations failed to yield any significant differences. The results provide further evidence to support the contention that athletes use reputation information as a basis for their initial expectancies of coaches, and such expectancies have the potential to influence athletes' behavior during coach-athlete interactions. The findings also indicate that expectancies based on positive information may be more powerful than negatively framed expectancies, and can be harnessed by coaches as a means of developing effective relationships with their athletes. © 2013 John Wiley & Sons A/S.

Promoting cooperation by reputation-driven group formation

NASA Astrophysics Data System (ADS)

Yang, Han-Xin; Wang, Zhen

2017-02-01

In previous studies of the spatial public goods game, each player is able to establish a group. However, in real life, some players cannot successfully organize groups for various reasons. In this paper, we propose a mechanism of reputation-driven group formation, in which groups can only be organized by players whose reputation reaches or exceeds a threshold. We define a player’s reputation as the frequency of cooperation in the last T time steps. We find that the highest cooperation level can be obtained when groups are only established by pure cooperators who always cooperate in the last T time steps. Effects of the memory length T on cooperation are also studied.

Fujimoto, Kayo; Snijders, Tom A. B.; Valente, Thomas W.

2016-01-01

In this study, we examined the dynamics of the perception of “dislike” ties (reputational dislike) among adolescents within the contexts of friendship, perceived popularity, substance use, and Facebook use. Survey data were collected from a longitudinal sample of 238 adolescents from the 11th and 12th grades in one California high school. We estimated stochastic actor-based network dynamic models, using reports of reputational dislike, friendships, and perceived popularity, to identify factors associated with the maintenance and generation reputational dislike ties. The results showed that high-status adolescents and more frequent Facebook users tended to become perceived as or stay disliked by their peers over time. There was a tendency for friendships to promote the creation and maintenance of reputational disliking but not vice versa. Adolescents tended to perceive others as disliked when their friends also perceived them as disliked. There was no evidence that either cigarette smoking or drinking alcohol affected reputational dislike dynamics. This study highlights the important role that the hierarchical peer system, online peer context, and friendships play in driving information diffusion of negative peer relations among adolescents.

Multiple gossip statements and their effect on reputation and trustworthiness.

PubMed

Sommerfeld, Ralf D; Krambeck, Hans-Jürgen; Milinski, Manfred

2008-11-07

Empirical and theoretical evidence from various disciplines indicates that reputation, reputation building and trust are important for human cooperation, social behaviour and economic progress. Recently, it has been shown that reputation gained in games of indirect reciprocity can be transmitted by gossip. But it has also been shown that gossiping has a strong manipulative potential. We propose that this manipulative potential is alleviated by the abundance of gossip. Multiple gossip statements give a better picture of the actual behaviour of a person, and thus inaccurate or fake gossip has little power as long as it is in the minority. In addition, we investigate the supposedly strong connection between reciprocity, reputation and trust. The results of this experimental study (with 11 groups of 12 students each) document that gossip quantity helps to direct cooperation towards cooperators. Moreover, reciprocity, trust and reputations transferred via gossip are positively correlated. This interrelation might have helped to reach the high levels of cooperation that can be observed in humans.

The influence of company reputation or what is often referred to as corporate reputation on branding strategy and producing intangible asset for different industries has been researched in western countries, but there is a gap for the generalizability of findings to countries out of the United State and Europe. To establish the western researcher's external validity of theories in other countries and to obtain a better understanding of the influences of branding and company reputation on pharmaceutical business markets, the researchers applied this study for Iran, a country in the Middle East. The obtained results using SEM (by P.L.S. 2.0 software) showed a good relationship between value creation and brand differentiation (β =0.360 and t-value = 3.167), between corporate communication and brand differentiation (β = 0.022 and t-value = 3.668), and between strategic resources and brand differentiation (β = 0.289 and t-value = 2.247). This study is a pioneering attempt in Iran to measure the impact of corporate reputation on brand differentiation strategy.

Multiple reputation domains and cooperative behaviour in two Latin American communities

PubMed Central

Macfarlan, Shane J.; Lyle, Henry F.

2015-01-01

Reputations are a ubiquitous feature of human social life, and a large literature has been dedicated to explaining the relationship between prosocial reputations and cooperation in social dilemmas. However, humans form reputations in domains other than prosociality, such as economic competency that could affect cooperation. To date, no research has evaluated the relative effects of multiple reputation domains on cooperation. To bridge this gap, we analyse how prosocial and competency reputations affect cooperation in two Latin American communities (Bwa Mawego, Dominica, and Pucucanchita, Peru) across a number of social contexts (Dominica: labour contracting, labour exchange and conjugal partnership formation; Peru: agricultural and health advice network size). First, we examine the behavioural correlates of prosocial and competency reputations. Following, we analyse whether prosocial, competency, or both reputation domains explain the flow of cooperative benefits within the two communities. Our analyses suggest that (i) although some behaviours affect both reputation domains simultaneously, each reputation domain has a unique behavioural signature; and (ii) competency reputations affect cooperation across a greater number of social contexts compared to prosocial reputations. Results are contextualized with reference to the social markets in which behaviour is embedded and a call for greater theory development is stressed. PMID:26503682

2017-09-01

This 11-month study analyzed illicit drug sales on the anonymous Tor network, with a focus on investigating whether a seller's reputation and capacity increased daily drug sales. The data were gathered from Silkkitie, the Finnish version of the Silk Road, by web crawling the site on a daily basis from (November 2014 to September 2015). The data include information on sellers (n=260) and products (n=3823). The measurements include the sellers' reputation, the sale amounts (in euros), the number of available products and the types of drugs sold. The sellers' capacity was measured using their full sales potential (in euros). Fixed-effects regression models were used to estimate the effects of sellers' reputation and capacity; these models were adjusted for the types of drugs sold. Overall, illicit drug sales totalled over 2 million euros during the study, but many products were not sold at all, and sellers were active for only a short time on average (mean=62.8days). Among the products sold, stimulants were most widely purchased, followed by cannabis, MDMA, and psychedelics. A seller's reputation and capacity were both associated with drug sales. The Tor network has enabled a transformation in drug sales. Due to the network's anonymity, the seller's reputation and capacity both have an impact on sales. Copyright © 2017 Elsevier B.V.

Young, rural Black men are disproportionately affected by sexually transmitted infections (STIs), a consequence, in part, of multiple sexual partnerships. We conducted a prospective study that examined the influence of masculinity ideology on changes in numbers of sexual partners in this population. We focused on a set of high-risk attitudes termed reputational masculinity. Community disadvantage during young adulthood was examined as a risk factor for reputational masculinity ideology, and vocational commitment was examined as a potential protective factor. The sample included 505 African American men ages 19 to 22 from high-poverty rural communities. Men reported their numbers of sexual partners during the past three months, masculinity ideology, community disadvantage, and vocational commitment. Follow-up data were collected 18 months after baseline assessment. Negative binomial modeling was used to test study hypotheses. Results indicated that community disadvantage was associated with increases in reputational masculinity during early adulthood, which in turn were linked to increases in numbers of sexual partners. Vocational commitment interacted with reputational masculinity to forecast numbers of sexual partners, attenuating the influence of reputational masculinity. Reputational masculinity and promotion of engagement with the workplace may be important targets for interventions designed to reduce sexual risk behavior.

Rejection of unfair offers can be driven by negative emotions, evidence from modified ultimatum games with anonymity.

The rejection of unfair offers can be affected by both negative emotions (e.g. anger and moral disgust) and deliberate cognitive processing of behavioral consequences (e.g. concerns of maintaining social fairness and protecting personal reputation). However, whether negative emotions are sufficient to motivate this behavior is still controversial. With modified ultimatum games, a recent study (Yamagishi T, et al. (2009) Proc Natl Acad Sci USA 106:11520-11523) found that people reject unfair offers even when this behavior increases inequity, and even when they could not communicate to the proposers. Yamagishi suggested that rejection of unfair offers could occur without people's concerning of maintaining social fairness, and could be driven by negative emotions. However, as anonymity was not sufficiently guaranteed in Yamagishi's study, the rejection rates in their experiments may have been influenced by people's concerns of protecting personal reputation (reputational concerns) in addition to negative emotions; thus, it was unclear whether the rejection was driven by negative emotions, or by reputational concerns, or both. In the present study, with specific methods to ensure anonymity, the effect of reputational concerns was successfully ruled out. We found that in a private situation in which rejection could not be driven by reputational concerns, the rejection rates of unfair offers were significantly larger than zero, and in public situations in which rejection rates could be influenced by both negative emotions and reputational concerns, rejection rates were significantly higher than that in the private situation. These results, together with Yamagishi's findings, provided more complete evidence suggesting (a) that the rejection of unfair offers can be driven by negative emotions and (b) that deliberate cognitive processing of the consequences of the behavior can increase the rejection rate, which may benefit social cooperation.

Childhood peer reputation as a predictor of competence and symptoms 10 years later.

Gest, Scott D; Sesma, Arturo; Masten, Ann S; Tellegen, Auke

2006-08-01

This study examined the differential developmental significance of multiple domains of peer reputation in childhood for current and future competence and symptoms. Participants were 205 children from a normative school cohort who completed assessments in grades 3-6 and then again 10 years later. Through re-analysis of original data from the Revised Class Play (RCP; N=612), new narrow-band subscales were examined as distinct correlates and predictors of competence in age-relevant developmental tasks and psychological well being as indexed by internalizing symptoms. Findings support the differentiation of peer exclusion, withdrawal, and sadness within the broad sensitive-isolated domain of reputation, as well as the distinctive meaning of reputations for Popularity-Leadership and Prosocial Behavior within the broad Sociable-Leader domain. When the Sensitive-Isolated predictors were considered, academic and job competence at the 10-year follow-up were predicted uniquely and negatively by peer exclusion, problems in the social and romantic domains were predicted distinctively by withdrawal from peers, and internalizing symptoms were uniquely predicted by childhood reputation as Sad-Sensitive. When the Sociable-Leader predictors were considered, academic and (for ethnic minority youth) job success was predicted by a Prosocial reputation, social success was forecasted by Popularity-Leadership, and romantic competence was predicted positively by Popularity-Leadership and negatively by Prosocial reputation. Negative academic and job outcomes were also predicted by a childhood reputation as Aggressive-Disruptive. Results are discussed in relation to conceptualizing and measuring peer social competence and its relation to later adaptation.

The Reputational Consequences of Failed Replications and Wrongness Admission among Scientists

Scientists are dedicating more attention to replication efforts. While the scientific utility of replications is unquestionable, the impact of failed replication efforts and the discussions surrounding them deserve more attention. Specifically, the debates about failed replications on social media have led to worry, in some scientists, regarding reputation. In order to gain data-informed insights into these issues, we collected data from 281 published scientists. We assessed whether scientists overestimate the negative reputational effects of a failed replication in a scenario-based study. Second, we assessed the reputational consequences of admitting wrongness (versus not) as an original scientist of an effect that has failed to replicate. Our data suggests that scientists overestimate the negative reputational impact of a hypothetical failed replication effort. We also show that admitting wrongness about a non-replicated finding is less harmful to one’s reputation than not admitting. Finally, we discovered a hint of evidence that feelings about the replication movement can be affected by whether replication efforts are aimed one’s own work versus the work of another. Given these findings, we then present potential ways forward in these discussions. PMID:26650842

Involvement of the Ventrolateral Prefrontal Cortex in Learning Others' Bad Reputations and Indelible Distrust.

A bad reputation can persistently affect judgments of an individual even when it turns out to be invalid and ought to be disregarded. Such indelible distrust may reflect that the negative evaluation elicited by a bad reputation transfers to a person. Consequently, the person him/herself may come to activate this negative evaluation irrespective of the accuracy of the reputation. If this theoretical model is correct, an evaluation-related brain region will be activated when witnessing a person whose bad reputation one has learned about, regardless of whether the reputation is deemed valid or not. Here, we tested this neural hypothesis with functional magnetic resonance imaging (fMRI). Participants memorized faces paired with either a good or a bad reputation. Next, they viewed the faces alone and inferred whether each person was likely to cooperate, first while retrieving the reputations, and then while trying to disregard them as false. A region of the left ventrolateral prefrontal cortex (vlPFC), which may be involved in negative evaluation, was activated by faces previously paired with bad reputations, irrespective of whether participants attempted to retrieve or disregard these reputations. Furthermore, participants showing greater activity of the left ventrolateral prefrontal region in response to the faces with bad reputations were more likely to infer that these individuals would not cooperate. Thus, once associated with a bad reputation, a person may elicit evaluation-related brain responses on their own, thereby evoking distrust independently of their reputation.

Young children are more generous when others are aware of their actions.

Adults frequently employ reputation-enhancing strategies when engaging in prosocial acts, behaving more generously when their actions are likely to be witnessed by others and even more so when the extent of their generosity is made public. This study examined the developmental origins of sensitivity to cues associated with reputationally motivated prosociality by presenting five-year-olds with the option to provide one or four stickers to a familiar peer recipient at no cost to themselves. We systematically manipulated the recipient's knowledge of the actor's choices in two different ways: (1) occluding the recipient's view of both the actor and the allocation options and (2) presenting allocations in opaque containers whose contents were visible only to the actor. Children were consistently generous only when the recipient was fully aware of the donation options; in all cases in which the recipient was not aware of the donation options, children were strikingly ungenerous. These results demonstrate that five-year-olds exhibit "strategic prosociality," behaving differentially generous as a function of the amount of information available to the recipient about their actions. These findings suggest that long before they develop a rich understanding of the social significance of reputation or are conscious of complex strategic reasoning, children behave more generously when the details of their prosocial actions are available to others.

The reputational and social network benefits of prosociality in an Andean community

PubMed Central

Lyle, Henry F.; Smith, Eric A.

2014-01-01

Several theories have emerged to explain how group cooperation (collective action) can arise and be maintained in the face of incentives to engage in free riding. Explanations focusing on reputational benefits and partner choice have particular promise for cases in which punishment is absent or insufficient to deter free riding. In indigenous communities of highland Peru, collective action is pervasive and provides critical benefits. Participation in collective action is unequal across households, but all households share its benefits. Importantly, investment in collective action involves considerable time, energy, and risk. Differential participation in collective action can convey information about qualities of fellow community members that are not easily observable otherwise, such as cooperative intent, knowledge, work ethic, skill, and/or physical vitality. Conveying such information may enhance access to adaptive support networks. Interview and observational data collected in a Peruvian highland community indicate that persons who contributed more to collective action had greater reputations as reliable, hard workers with regard to collective action and also were considered the most respected, influential, and generous people in the community. Additionally, household heads with greater reputations had more social support partners (measured as network indegree centrality), and households with larger support networks experienced fewer illness symptoms.

Reputation systems promote cooperation and deter antisocial behavior in groups. Little is known, however, about how and why people share reputational information. Here, we seek to establish the existence and dynamics of prosocial gossip, the sharing of negative evaluative information about a target in a way that protects others from antisocial or exploitative behavior. We present a model of prosocial gossip and the results of 4 studies testing the model's claims. Results of Studies 1 through 3 demonstrate that (a) individuals who observe an antisocial act experience negative affect and are compelled to share information about the antisocial actor with a potentially vulnerable person, (b) sharing such information reduces negative affect created by observing the antisocial behavior, and (c) individuals possessing more prosocial orientations are the most motivated to engage in such gossip, even at a personal cost, and exhibit the greatest reduction in negative affect as a result. Study 4 demonstrates that prosocial gossip can effectively deter selfishness and promote cooperation. Taken together these results highlight the roles of prosocial motivations and negative affective reactions to injustice in maintaining reputational information sharing in groups. We conclude by discussing implications for reputational theories of the maintenance of cooperation in human groups.

The purpose of this study was to examine the relations of a measure of children's dispositional prosocial behavior (i.e., peer nominations) to individual differences in children's negative emotionality, regulation, and social functioning. Children with prosocial reputations tended to be high in constructive social skills (i.e., socially appropriate behavior and constructive coping) and attentional regulation, and low in negative emotionality. The relations of children's negative emotionality to prosocial reputation were moderated by level of dispositional attentional regulation. In addition, the relations of prosocial reputation to constructive social skills and parent-reported negative emotionality (for girls) increased with age. Vagal tone, a marker of physiological regulation, was negatively related to girls' prosocial reputation.

A community's reputation may have implications for self-esteem, morale, or other health outcomes of residents. In this study, we introduce a means of quantifying the reputation of communities in Calgary, Canada based on their portrayal in the daily citywide newspaper. Publication dates were selected from an 8.5-year period using constructed week sampling. For communities designated as high or low in well-being, sampled references were rated as positive, negative, or neutral in topic, by two independent raters who were blind to community identity. Findings suggest that the print media represent a convenient and discriminating data source for characterising some aspects of community reputation.

Once Dishonest, Always Dishonest? The Impact of Perceived Pervasiveness of Moral Evaluations of the Self on Motivation to Restore a Moral Reputation

Pagliaro, Stefano; Ellemers, Naomi; Barreto, Manuela; Di Cesare, Cecilia

Four studies specify how moral evaluations of the self regulate behavior aimed at restoring a moral reputation. We propose that people care about evaluations of themselves as moral or immoral because these are perceived as more consequential than other types of information. Therefore people are more inclined to restore their image after being negatively evaluated in terms of morality rather than competence. Studies 1 and 2 revealed that moral information was perceived as having a more enduring impact on one’s reputation, and was more strongly related to anticipate intra-group respect and self-views, than competence and sociability information. This perceived pervasiveness of moral (vs. competence) evaluations mediated intentions to justify and explain one’s behavior (Study 3). Study 4 finally showed that being seen as lacking in morality elicited threat and coping responses, which induced subsequent tendencies to repair one’s moral reputation. PMID:27199821

Trust is a particularly under-studied aspect of social relationships in older age. In the current study, young (n = 35) and older adults (n = 35) completed a series of one-shot social economic trust games in which they invested real money with trustees. There were potential gains with each investment and also a risk of losing everything if the trustee was untrustworthy. The reputation and facial appearance of each trustee were manipulated to make them appear more or less trustworthy. Results revealed that young and older adults invest more money with trustees whose facial appearance and reputation indicate that they are trustworthy rather than untrustworthy. However, older adults were more likely than young to invest with trustees who had a reputation for being untrustworthy. We discuss whether age-related differences in responding to negative information may account for an age-related increase in trust, particularly when trusting someone with a reputation for being uncooperative.

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

PubMed

Kuwabara, Ko

2015-03-01

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

Punishment and reputation in spatial public goods games.

PubMed

Brandt, Hannelore; Hauert, Christoph; Sigmund, Karl

2003-05-22

The puzzle of the emergence of cooperation between unrelated individuals is shared across diverse fields of behavioural sciences and economics. In this article we combine the public goods game originating in economics with evolutionary approaches traditionally used in biology. Instead of pairwise encounters, we consider the more complex case of groups of three interacting individuals. We show that territoriality is capable of promoting cooperative behaviour, as in the case of the Prisoner's Dilemma. Moreover, by adding punishment opportunities, the readiness to cooperate is greatly enhanced and asocial strategies can be largely suppressed. Finally, as soon as players carry a reputation for being willing or unwilling to punish, highly cooperative and fair outcomes are achieved. This group-beneficial result is obtained, intriguingly, by making individuals more likely to exploit their co-players if they can get away with it. Thus, less-cooperative individuals make more-cooperative societies.

There Is More to Transparency than Meets the Eye: The Impact of Mandatory Disclosure Laws Aimed at Promoting Breastfeeding.

2014-01-01

Requiring hospitals to inform patients of clinical best practices and to disclose performance data are two common regulatory strategies for improving healthcare. Proponents of such mandatory disclosure laws--sometimes referred to as "targeted transparency "--argue that they increase patient awareness and thereby create reputational incentives for hospitals to improve their performance. Evaluation of targeted transparency typically focuses on patient responses to information and changes in hospital behavior based on reputational concerns. This standard account, however, overlooks other important ways targeted transparency can influence hospital performance. This article presents a case study of disclosure laws designed to promote breastfeeding to illustrate how targeted transparency can influence hospitals independently of its effects on patients' choice of provider or hospitals' fear of losing business. We found that mandatory disclosure laws emboldened state regulators to take a more aggressive approach to enforcement of hospital regulations, empowered nurse managers to advocate more effectively within hospitals for changes in hospital policies, and enabled nurse managers to implement verifiable performance goals for clinical staff under their supervision. These findings suggest that the study of mandatory disclosure more generally--in areas such as financial regulation, environmental protection, food labeling, and workplace safety--would benefit by analyzing not only its influence on public awareness and its reputational effects but also how regulators use transparency laws and how managers within regulated entities employ the information that the laws provide.

An Experimental Testbed for Evaluation of Trust and Reputation Systems

NASA Astrophysics Data System (ADS)

Kerr, Reid; Cohen, Robin

To date, trust and reputation systems have often been evaluated using methods of their designers’ own devising. Recently, we demonstrated that a number of noteworthy trust and reputation systems could be readily defeated, revealing limitations in their original evaluations. Efforts in the trust and reputation community to develop a testbed have yielded a successful competition platform, ART. This testbed, however, is less suited to general experimentation and evaluation of individual trust and reputation technologies. In this paper, we propose an experimentation and evaluation testbed based directly on that used in our investigations into security vulnerabilities in trust and reputation systems for marketplaces. We demonstrate the advantages of this design, towards the development of more thorough, objective evaluations of trust and reputation systems.

Examining corporate reputation judgments with generalizability theory.

Highhouse, Scott; Broadfoot, Alison; Yugo, Jennifer E; Devendorf, Shelba A

2009-05-01

The researchers used generalizability theory to examine whether reputation judgments about corporations function in a manner consistent with contemporary theory in the corporate-reputation literature. University professors (n = 86) of finance, marketing, and human resources management made repeated judgments about the general reputations of highly visible American companies. Minimal variability in the judgments is explained by items, time, persons, and field of specialization. Moreover, experts from the different specializations reveal considerable agreement in how they weigh different aspects of corporate performance in arriving at their global reputation judgments. The results generally support the theory of the reputation construct and suggest that stable estimates of global reputation can be achieved with a small number of items and experts.

Humans make decisions about when and with whom to cooperate based on their reputations. People either learn about others by direct interaction or by observing third-party interactions or gossip. An important question is whether other animal species, especially our closest living relatives, the nonhuman great apes, also form reputations of others. In Study 1, chimpanzees, bonobos, orangutans, and 2.5-year-old human children experienced a nice experimenter who tried to give food/toys to the subject and a mean experimenter who interrupted the food/toy giving. In studies 2 and 3, nonhuman great apes and human children could only passively observe a similar interaction, in which a nice experimenter and a mean experimenter interacted with a third party. Orangutans and 2.5-year-old human children preferred to approach the nice experimenter rather than the mean one after having directly experienced their respective behaviors. Orangutans, chimpanzees, and 2.5-year-old human children also took into account experimenter actions toward third parties in forming reputations. These studies show that the human ability to form direct and indirect reputation judgment is already present in young children and shared with at least some of the other great apes.

Rejection of Unfair Offers Can Be Driven by Negative Emotions, Evidence from Modified Ultimatum Games with Anonymity

PubMed Central

2012-01-01

The rejection of unfair offers can be affected by both negative emotions (e.g. anger and moral disgust) and deliberate cognitive processing of behavioral consequences (e.g. concerns of maintaining social fairness and protecting personal reputation). However, whether negative emotions are sufficient to motivate this behavior is still controversial. With modified ultimatum games, a recent study (Yamagishi T, et al. (2009) Proc Natl Acad Sci USA 106∶11520–11523) found that people reject unfair offers even when this behavior increases inequity, and even when they could not communicate to the proposers. Yamagishi suggested that rejection of unfair offers could occurr without people’s concerning of maintaining social fairness, and could be driven by negative emotions. However, as anonymity was not sufficiently guaranteed in Yamagishi’s study, the rejection rates in their experiments may have been influenced by people’s concerns of protecting personal reputation (reputational concerns) in addition to negative emotions; thus, it was unclear whether the rejection was driven by negative emotions, or by reputational concerns, or both. In the present study, with specific methods to ensure anonymity, the effect of reputational concerns was successfully ruled out. We found that in a private situation in which rejection could not be driven by reputational concerns, the rejection rates of unfair offers were significantly larger than zero, and in public situations in which rejection rates could be influenced by both negative emotions and reputational concerns, rejection rates were significantly higher than that in the private situation. These results, together with Yamagishi’s findings, provided more complete evidence suggesting (a) that the rejection of unfair offers can be driven by negative emotions and (b) that deliberate cognitive processing of the consequences of the behavior can increase the rejection rate, which may benefit social cooperation.

Indirect reciprocity provides a narrow margin of efficiency for costly punishment

PubMed Central

Iwasa, Yoh; Nowak, Martin A.

2008-01-01

Indirect reciprocity1-5 is a key mechanism for the evolution of human cooperation. Our behavior toward other people depends not only on what they have done to us, but also on what they have done to others. Indirect reciprocity works via reputation5-17. The standard model of indirect reciprocity offers a binary choice: people can either cooperate or defect. Cooperation implies a cost for the donor and a benefit for the recipient. Defection has no cost and yields no benefit. Currently there is considerable interest in studying the effect of costly (or altruistic) punishment on human behavior18-25. Punishment implies a cost for the punished person. Costly punishment means that the punisher also pays a cost. It has been suggested that costly punishment between individuals can promote cooperation. Here we study the role of costly punishment in an explicit model of indirect reciprocity. We analyze all social norms, which depend on the action of the donor and the reputation of the recipient. We allow errors in assigning reputation and study gossip as a mechanism for establishing coherence. We characterize all strategies that allow the evolutionary stability of cooperation. Some of those strategies use costly punishment, while others do not. We find that punishment strategies typically reduce the average payoff of the population. Consequently, there is only a small parameter region where costly punishment leads to an efficient equilibrium. In most cases, the population does better by not using costly punishment. The efficient strategy for indirect reciprocity is to withhold help for defectors rather than punish them. PMID:19122640

Young Children Are More Generous When Others Are Aware of Their Actions

Leimgruber, Kristin L.; Shaw, Alex; Santos, Laurie R.; Olson, Kristina R.

2012-01-01

Adults frequently employ reputation-enhancing strategies when engaging in prosocial acts, behaving more generously when their actions are likely to be witnessed by others and even more so when the extent of their generosity is made public. This study examined the developmental origins of sensitivity to cues associated with reputationally motivated prosociality by presenting five-year-olds with the option to provide one or four stickers to a familiar peer recipient at no cost to themselves. We systematically manipulated the recipient’s knowledge of the actor’s choices in two different ways: (1) occluding the recipient’s view of both the actor and the allocation options and (2) presenting allocations in opaque containers whose contents were visible only to the actor. Children were consistently generous only when the recipient was fully aware of the donation options; in all cases in which the recipient was not aware of the donation options, children were strikingly ungenerous. These results demonstrate that five-year-olds exhibit “strategic prosociality,” behaving differentially generous as a function of the amount of information available to the recipient about their actions. These findings suggest that long before they develop a rich understanding of the social significance of reputation or are conscious of complex strategic reasoning, children behave more generously when the details of their prosocial actions are available to others.

Preschoolers affect others' reputations through prosocial gossip.

PubMed

Engelmann, Jan M; Herrmann, Esther; Tomasello, Michael

Providing evaluative information to others about absent third parties helps them to identify cooperators and avoid cheaters. Here, we show that 5-year-olds, but not 3-year-olds, reliably engage in such prosocial gossip. In an experimental setting, 5-year-old children spontaneously offered relevant reputational information to guide a peer towards a cooperative partner. Three-year-old children offered such evaluative information only rarely, although they still showed a willingness to inform in a non-evaluative manner. A follow-up study revealed that one component involved in this age difference is children's developing ability to provide justifications. The current results extend previous work on young children's tendency to manage their own reputation by showing that preschoolers also influence others' reputations via gossip. © 2016 The British Psychological Society.

For the security problems of the hierarchical P2P network (HPN), the paper presents a security clustering algorithm based on reputation (CABR). In the algorithm, we take the reputation mechanism for ensuring the security of transaction and use cluster for managing the reputation mechanism. In order to improve security, reduce cost of network brought by management of reputation and enhance stability of cluster, we select reputation, the historical average online time, and the network bandwidth as the basic factors of the comprehensive performance of node. Simulation results showed that the proposed algorithm improved the security, reduced the network overhead, and enhanced stability of cluster.

Reputation is an important social construct in science, which enables informed quality assessments of both publications and careers of scientists in the absence of complete systemic information. However, the relation between reputation and career growth of an individual remains poorly understood, despite recent proliferation of quantitative research evaluation methods. Here, we develop an original framework for measuring how a publication's citation rate Δc depends on the reputation of its central author i, in addition to its net citation count c. To estimate the strength of the reputation effect, we perform a longitudinal analysis on the careers of 450 highly cited scientists, using the total citations Ci of each scientist as his/her reputation measure. We find a citation crossover c×, which distinguishes the strength of the reputation effect. For publications with c < c×, the author's reputation is found to dominate the annual citation rate. Hence, a new publication may gain a significant early advantage corresponding to roughly a 66% increase in the citation rate for each tenfold increase in Ci. However, the reputation effect becomes negligible for highly cited publications meaning that, for c ≥ c×, the citation rate measures scientific impact more transparently. In addition, we have developed a stochastic reputation model, which is found to reproduce numerous statistical observations for real careers, thus providing insight into the microscopic mechanisms underlying cumulative advantage in science.

SoRS: Social recommendation using global rating reputation and local rating similarity

NASA Astrophysics Data System (ADS)

Qian, Fulan; Zhao, Shu; Tang, Jie; Zhang, Yanping

2016-11-01

Recommendation is an important and also challenging problem in online social networks. It needs to consider not only users' personalized interests, but also social relations between users. Indeed, in practice, users are often inclined to accept recommendations from friends or opinion leaders (users with high reputations). In this paper, we present a novel recommendation framework, social recommendation using global rating reputation and local rating similarity, which combine user reputation and social similarity based on ratings. User reputation can be obtained by iteratively calculating the correlation of historical ratings of user and intrinsic qualities of items. We view the user reputation as the user's global influence and the similarity based on rating of social relation as the user's local influence, introduce it in the basic social recommender model. Thus users with high reputation have a strong influence on the others, and on the other hand, the effect of a user with low reputation has been weakened. The recommendation accuracy of proposed framework can be improved by effectively removing nature noise because of less rigorous user ratings and strengthening the effect of user influence with high reputation. We also improve the similarity based on ratings by avoiding the high similarity with the less common ratings between friends. We evaluate our approach on three datasets including Movielens, Epinions and Douban. Empirical results demonstrate that proposed framework achieves significant improvements on recommendation accuracy. User reputation and local similarity which are both based on ratings have a lot of helpful in improvement of prediction accuracy. The reputation also can help to improve the recommendation precision with the small training sets.

Online written consultation, telephone consultation and offline appointment: An examination of the channel effect in online health communities.

PubMed

Wu, Hong; Lu, Naiji

2017-11-01

The emergence of online health communities broadens and diversifies channels for patient-doctor interaction. Given limited medical resources, online health communities aim to provide better treatment by decreasing medical costs, making full use of available resources and providing more diverse channels for patients. This research examines how online channel usage affects offline channels, i.e., "Online Booking, Service in Hospitals" (OBSH), and how the channel effects change with doctors' online and offline reputation. The study uses data of 4254 doctors from a Chinese online health community. Our findings demonstrate a strong relationship between online health communities and offline hospital communication with an important moderating role for reputation. There are significant channel effects, wherein written consultation complements OBSH (β=3.320, p<0.10), but telephone consultation can be a readily substitute for OBSH (β=-9.854, p<0.001). We also find that doctors with higher online and offline reputations can attract more patients to use the OBSH (β online =0.433, p<0.001; β offline =2.318&2.123, p<0.001). Third, channel effects fluctuate, relative to doctors' online and offline reputations: doctors with higher online reputations mitigate substitution effects between telephone consultation and OBSH (β=0.064, p<0.01), and doctors with higher offline reputations mitigate complementary effects between written consultation and OBSH (β=-1.586&-1.417, p<0.001). This study contributes to both knowledge and practice. This study shows that there is channel effect in healthcare, websites' managers can encourage physicians to provide online services, especially for these physicians who do not have enough patients.

Concern for Group Reputation Increases Prosociality in Young Children.

2018-02-01

The motivation to build and maintain a positive personal reputation promotes prosocial behavior. But individuals also identify with their groups, and so it is possible that the desire to maintain or enhance group reputation may have similar effects. Here, we show that 5-year-old children actively invest in the reputation of their group by acting more generously when their group's reputation is at stake. Children shared significantly more resources with fictitious other children not only when their individual donations were public rather than private but also when their group's donations (effacing individual donations) were public rather than private. These results provide the first experimental evidence that concern for group reputation can lead to higher levels of prosociality.

Who Deserves My Trust? Cue-Elicited Feedback Negativity Tracks Reputation Learning in Repeated Social Interactions.

PubMed

Li, Diandian; Meng, Liang; Ma, Qingguo

2017-01-01

Trust and trustworthiness contribute to reciprocal behavior and social relationship development. To make better decisions, people need to evaluate others' trustworthiness. They often assess this kind of reputation by learning through repeated social interactions. The present event-related potential (ERP) study explored the reputation learning process in a repeated trust game where subjects made multi-round decisions of investment to different partners. We found that subjects gradually learned to discriminate trustworthy partners from untrustworthy ones based on how often their partners reciprocated the investment, which was indicated by their own investment decisions. Besides, electrophysiological data showed that the faces of the untrustworthy partners induced larger feedback negativity (FN) amplitude than those of the trustworthy partners, but only in the late phase of the game. The ERP results corresponded with the behavioral pattern and revealed that the learned trustworthiness differentiation was coded by the cue-elicited FN component. Consistent with previous research, our findings suggest that the anterior cue-elicited FN reflects the reputation appraisal and tracks the reputation learning process in social interactions.

Arbitrary Inequality in Reputation Systems

Trust is an essential condition for exchange. Large societies must substitute the trust traditionally provided through kinship and sanctions in small groups to make exchange possible. The rise of internet-supported reputation systems has been celebrated for providing trust at a global scale, enabling the massive volumes of transactions between distant strangers that are characteristic of modern human societies. Here we problematize an overlooked side-effect of reputation systems: Equally trustworthy individuals may realize highly unequal exchange volumes. We report the results of a laboratory experiment that shows emergent differentiation between ex ante equivalent individuals when information on performance in past exchanges is shared. This arbitrary inequality results from cumulative advantage in the reputation-building process: Random initial distinctions grow as parties of good repute are chosen over those lacking a reputation. We conjecture that reputation systems produce artificial concentration in a wide range of markets and leave superior but untried exchange alternatives unexploited.

The path of patient loyalty and the role of doctor reputation.

PubMed

Torres, Eduardo; Vasquez-Parraga, Arturo Z; Barra, Cristobal

2009-01-01

Patient loyalty to doctors is relevant to medical services in which doctor-patient relationships are central and for which competition has increased in recent years. This study aims at understanding the process whereby patients develop loyalty to their doctor and doctor reputation has a moderating role. Based on a randomization of subjects, the study offers and tests an explanation chain representing key variables determining patient loyalty: patient commitment, trust and satisfaction, and doctor reputation. Primary data was collected using a structured questionnaire from a quota sample of regular patients in a large city in South America. The patients most committed to their doctor are more loyal to them. In turn, commitment is determined by patient trust, which is determined by patient satisfaction. Doctor reputation positively influences both patient trust and satisfaction. The explanation chain not only gives an account of how patient loyalty is formed; it also identifies a path health professionals can follow to secure patient loyalty.

The effects of reputational and social knowledge on cooperation

PubMed Central

Gallo, Edoardo; Yan, Chang

2015-01-01

The emergence and sustenance of cooperative behavior is fundamental for a society to thrive. Recent experimental studies have shown that cooperation increases in dynamic networks in which subjects can choose their partners. However, these studies did not vary reputational knowledge, or what subjects know about other’s past actions, which has long been recognized as an important factor in supporting cooperation. They also did not give subjects access to global social knowledge, or information on who is connected to whom in the group. As a result, it remained unknown how reputational and social knowledge foster cooperative behavior in dynamic networks both independently and by complementing each other. In an experimental setting, we show that global reputational knowledge is crucial to sustaining a high level of cooperation and welfare. Cooperation is associated with the emergence of dense and clustered networks with highly cooperative hubs. Global social knowledge has no effect on the aggregate level of cooperation. A community analysis shows that the addition of global social knowledge to global reputational knowledge affects the distribution of cooperative activity: cooperators form a separate community that achieves a higher cooperation level than the community of defectors. Members of the community of cooperators achieve a higher payoff from interactions within the community than members of the less cooperative community. PMID:25775544

The delinquency-drug relationship: the influence of social reputation and moral disengagement.

PubMed

Passini, Stefano

2012-04-01

A large number of studies have focused on the relationship between drug use and violent delinquency in adolescence. Most of these studies underline that even if substance use and delinquency often co-occur, they may result from common causes that increase the risk for both outcomes. In particular, the delinquency-drug relationship may be mediated both by the type of drug and the incidence of other variables. In this article, social reputation and moral disengagement are studied as predictors of both drug use and violent delinquency in a 336 adolescent participants. Results confirm the hypotheses that social reputation and moral disengagement predict drug use and delinquency and that heavy drug use predicts delinquency. Copyright © 2012 Elsevier Ltd.

Reputation-based partner choice promotes cooperation in social networks

Fu, Feng; Hauert, Christoph; Nowak, Martin A.; Wang, Long

2008-08-01

We investigate the cooperation dynamics attributed to the interplay between the evolution of individual strategies and evolution of individual partnerships. We focus on the effect of reputation on an individual’s partner-switching process. We assume that individuals can either change their strategies by imitating their partners or adjust their partnerships based on local information about reputations. We manipulate the partner switching in two ways; that is, individuals can switch from the lowest reputation partners, either to their partners’ partners who have the highest reputation (i.e., ordering in partnership) or to others randomly chosen from the entire population (i.e., randomness in partnership). We show that when individuals are able to alter their behavioral strategies and their social interaction partnerships on the basis of reputation, cooperation can prevail. We find that the larger temptation to defect and the denser the partner network, the more frequently individuals need to shift their partnerships in order for cooperation to thrive. Furthermore, an increasing tendency of switching to partners’ partners is more likely to lead to a higher level of cooperation. We show that when reputation is absent in such partner-switching processes, cooperation is much less favored than that of the reputation involved. Moreover, we investigate the effect of discounting an individual’s reputation on the evolution of cooperation. Our results highlight the importance of the consideration of reputation (indirect reciprocity) on the promotion of cooperation when individuals can adjust their partnerships.

Nucleus accumbens response to gains in reputation for the self relative to gains for others predicts social media use.

2013-01-01

Our reputation is important to us; we've experienced natural selection to care about our reputation. Recently, the neural processing of gains in reputation (positive social feedback concerning one's character) has been shown to occur in the human ventral striatum. It is still unclear, however, how individual differences in the processing of gains in reputation may lead to individual differences in real-world behavior. For example, in the real-world, one way that people currently maintain their reputation is by using social media websites, like Facebook. Furthermore, Facebook use consists of a social comparison component, where users observe others' behavior and can compare it to their own. Therefore, we hypothesized a relationship between the way the brain processes specifically self-relevant gains in reputation and one's degree of Facebook use. We recorded functional neuroimaging data while participants received gains in reputation, observed the gains in reputation of another person, or received monetary reward. We demonstrate that across participants, when responding to gains in reputation for the self, relative to observing gains for others, reward-related activity in the left nucleus accumbens predicts Facebook use. However, nucleus accumbens activity in response to monetary reward did not predict Facebook use. Finally, a control step-wise regression analysis showed that Facebook use primarily explains our results in the nucleus accumbens. Overall, our results demonstrate how individual sensitivity of the nucleus accumbens to the receipt of self-relevant social information leads to differences in real-world behavior.

The influence of an online auction's product price and e-retailer reputation on consumers' perception, attitude, and behavioral intention.

2011-06-01

Online auctions combine the conventional auction model with information technology. However, information asymmetry within such auctions causes risks and uncertainties that influence consumer purchase intentions. In this study, a 2 (product price: high vs. low) × 2 (e-retailer reputation: high vs. low) experimental design was used to understand whether the product price and e-retailer reputation will influence consumers' perceived risk, attitude toward the website and purchase intention. The results of this study indicate that perceived risk negatively influences consumer attitude toward the website and online purchase intention, while consumer attitude toward the website positively influences purchase intention. Moreover, involvement moderates the influence of product price and e-retailer reputation only on social risk but does not have a significant effect on consumer attitude toward the website. This study contributes to a more comprehensive understanding of online auction users' behavior. Finally, the managerial implications, limitations and future research directions are also provided. © 2011 The Authors.

The infamous among us: Enhanced reputational memory for uncooperative ingroup members.

PubMed

Hechler, Stefanie; Neyer, Franz J; Kessler, Thomas

2016-12-01

People remember uncooperative individuals better than cooperative ones. We hypothesize that this is particularly true when uncooperative individuals belong to one's ingroup, as their behavior violates positive expectations. Two studies examined the effect of minimal group categorization on reputational memory of the social behavior of particular ingroup and outgroup members. We manipulated uncooperative behavior as the unfair sharing of resources with ingroup members (Study 1), or as descriptions of cheating (Study 2). Participants evaluated several uncooperative and cooperative (and neutral) ingroup and outgroup members. In a surprise memory test, they had to recognize target faces and recall their behavior. We disentangled face recognition, reputational memory, and guessing biases with multinomial models of source monitoring. The results show enhanced reputational memory for uncooperative ingroup members, but not uncooperative outgroup members. In contrast, guessing behavior indicated that participants assumed more ingroup cooperation than outgroup cooperation. Our findings integrate prior research on memory for uncooperative person behavior and person memory in group contexts. We suggest that the ability to remember the uncooperative amidst the supposedly cooperative ingroup could stabilize intragroup cooperation. Copyright © 2016 Elsevier B.V. All rights reserved.

The Reputational Consequences of Generalized Trust

PubMed Central

Evans, Anthony M.; van de Calseyde, Philippe P. F. M.

2017-01-01

The present research examines the reputational consequences of generalized trust. High-trust individuals are seen as moral and sociable, but not necessarily competent. When controlling for other traits, there is a negative relationship between trust and perceived competence (Studies 1 and 2). Compared with optimism, generalized trust has stronger effects on morality and sociability (Study 2). Furthermore, people judge those who do not discriminate between trustworthy and untrustworthy groups (unconditional trustors) more negatively than those who only trust groups that are, in fact, trustworthy (conditional trustors). Unconditional trust and unconditional distrust are both viewed negatively (Study 3), even after controlling for attitudinal similarity (Study 4). Critically, both generalized trust and discriminant ability (i.e., conditional trust) have independent reputational benefits (Study 5). These studies suggest that generalized trust plays an important role in how we perceive and judge others. PMID:29251247

Inferring Reputation Promotes the Evolution of Cooperation in Spatial Social Dilemma Games

PubMed Central

Wang, Zhen; Wang, Lin; Yin, Zi-Yu; Xia, Cheng-Yi

2012-01-01

In realistic world individuals with high reputation are more likely to influence the collective behaviors. Due to the cost and error of information dissemination, however, it is unreasonable to assign each individual with a complete cognitive power, which means that not everyone can accurately realize others’ reputation situation. Here we introduce the mechanism of inferring reputation into the selection of potential strategy sources to explore the evolution of cooperation. Before the game each player is assigned with a randomly distributed parameter p denoting his ability to infer the reputation of others. The parameter p of each individual is kept constant during the game. The value of p indicates that the neighbor possessing highest reputation is chosen with the probability p and randomly choosing an opponent is left with the probability 1−p. We find that this novel mechanism can be seen as an universally applicable promoter of cooperation, which works on various interaction networks and in different types of evolutionary game. Of particular interest is the fact that, in the early stages of evolutionary process, cooperators with high reputation who are easily regarded as the potential strategy donors can quickly lead to the formation of extremely robust clusters of cooperators that are impervious to defector attacks. These clusters eventually help cooperators reach their undisputed dominance, which transcends what can be warranted by the spatial reciprocity alone. Moreover, we provide complete phase diagrams to depict the impact of uncertainty in strategy adoptions and conclude that the effective interaction topology structure may be altered under such a mechanism. When the estimation of reputation is extended, we also show that the moderate value of evaluation factor enables cooperation to thrive best. We thus present a viable method of understanding the ubiquitous cooperative behaviors in nature and hope that it will inspire further studies to resolve social dilemmas. PMID:22808120

Knowledge of identity and reputation: Do people have knowledge of others' perceptions?

PubMed

Solomon, Brittany C; Vazire, Simine

2016-09-01

It may be important to know when our impressions of someone differ from how that person sees him/herself and how others see that same person. We investigated whether people are aware of how their friends see themselves (knowledge of identity) and are seen by others (knowledge of reputation). Previous research indicates that, for physical attractiveness, romantic partners do have such knowledge of others' perceptions, but it is unknown whether people in platonic relationships also detect such discrepancies between their own perceptions and others'. We examined this phenomenon for a new set of characteristics: the Big Five personality traits. Our primary research questions pertained to identity accuracy and reputation accuracy (i.e., knowledge of a target's self-views and how others view the target, respectively) and identity insight and reputation insight (i.e., identity accuracy and reputation accuracy that cannot be accounted for by a potential artifact: perceivers assuming that others share their own views of targets). However, after a series of preliminary tests, we did not examine reputation insight, as several necessary conditions were not met, indicating that any effects would likely be spurious. We did find that perceivers can accurately infer a target's identity and reputation on global personality traits (identity and reputation accuracy), and that perceivers can sometimes accurately distinguish between their own perceptions of targets and targets' self-views, but not others' views of targets (i.e., identity, but not reputation, insight). Finally, we explored boundary conditions for knowledge of others' perceptions and whether knowledge of identity is correlated with knowledge of reputation.

Evaluating user reputation in online rating systems via an iterative group-based ranking method

NASA Astrophysics Data System (ADS)

Gao, Jian; Zhou, Tao

2017-05-01

Reputation is a valuable asset in online social lives and it has drawn increased attention. Due to the existence of noisy ratings and spamming attacks, how to evaluate user reputation in online rating systems is especially significant. However, most of the previous ranking-based methods either follow a debatable assumption or have unsatisfied robustness. In this paper, we propose an iterative group-based ranking method by introducing an iterative reputation-allocation process into the original group-based ranking method. More specifically, the reputation of users is calculated based on the weighted sizes of the user rating groups after grouping all users by their rating similarities, and the high reputation users' ratings have larger weights in dominating the corresponding user rating groups. The reputation of users and the user rating group sizes are iteratively updated until they become stable. Results on two real data sets with artificial spammers suggest that the proposed method has better performance than the state-of-the-art methods and its robustness is considerably improved comparing with the original group-based ranking method. Our work highlights the positive role of considering users' grouping behaviors towards a better online user reputation evaluation.

Reputation, a universal currency for human social interactions

2016-01-01

Decision rules of reciprocity include ‘I help those who helped me’ (direct reciprocity) and ‘I help those who have helped others’ (indirect reciprocity), i.e. I help those who have a reputation to care for others. A person's reputation is a score that members of a social group update whenever they see the person interacting or hear at best multiple gossip about the person's social interactions. Reputation is the current standing the person has gained from previous investments or refusal of investments in helping others. Is he a good guy, can I trust him or should I better avoid him as a social partner? A good reputation pays off by attracting help from others, even from strangers or members from another group, if the recipient's reputation is known. Any costly investment in others, i.e. direct help, donations to charity, investment in averting climate change, etc. increases a person's reputation. I shall argue and illustrate with examples that a person's known reputation functions like money that can be used whenever the person needs help. Whenever possible I will present tests of predictions of evolutionary theory, i.e. fitness maximizing strategies, mostly by economic experiments with humans. PMID:26729939

Methods for reliability evaluation of trust and reputation systems

NASA Astrophysics Data System (ADS)

Janiszewski, Marek B.

2016-09-01

Trust and reputation systems are a systematic approach to build security on the basis of observations of node's behaviour. Exchange of node's opinions about other nodes is very useful to indicate nodes which act selfishly or maliciously. The idea behind trust and reputation systems gets significance because of the fact that conventional security measures (based on cryptography) are often not sufficient. Trust and reputation systems can be used in various types of networks such as WSN, MANET, P2P and also in e-commerce applications. Trust and reputation systems give not only benefits but also could be a thread itself. Many attacks aim at trust and reputation systems exist, but such attacks still have not gain enough attention of research teams. Moreover, joint effects of many of known attacks have been determined as a very interesting field of research. Lack of an acknowledged methodology of evaluation of trust and reputation systems is a serious problem. This paper aims at presenting various approaches of evaluation such systems. This work also contains a description of generalization of many trust and reputation systems which can be used to evaluate reliability of such systems in the context of preventing various attacks.

Eyes are on us, but nobody cares: are eye cues relevant for strong reciprocity?

PubMed Central

Fehr, Ernst; Schneider, Frédéric

2010-01-01

Strong reciprocity is characterized by the willingness to altruistically reward cooperative acts and to altruistically punish norm-violating, defecting behaviours. Recent evidence suggests that subtle reputation cues, such as eyes staring at subjects during their choices, may enhance prosocial behaviour. Thus, in principle, strong reciprocity could also be affected by eye cues. We investigate the impact of eye cues on trustees' altruistic behaviour in a trust game and find zero effect. Neither the subjects who are classified as prosocial nor the subjects who are classified as selfish respond to these cues. In sharp contrast to the irrelevance of subtle reputation cues for strong reciprocity, we find a large effect of explicit, pecuniary reputation incentives on the trustees' prosociality. Trustees who can acquire a good reputation that benefits them in future interactions honour trust much more than trustees who cannot build a good reputation. These results cast doubt on hypotheses suggesting that strong reciprocity is easily malleable by implicit reputation cues not backed by explicit reputation incentives. PMID:20031986

The influence of prior reputation and reciprocity on dynamic trust-building in adults with and without autism spectrum disorder.

PubMed

Maurer, Cornelius; Chambon, Valerian; Bourgeois-Gironde, Sacha; Leboyer, Marion; Zalla, Tiziana

2018-03-01

The present study was designed to investigate the effects of reputational priors and direct reciprocity on the dynamics of trust building in adults with (N = 17) and without (N = 25) autism spectrum disorder (ASD) using a multi-round Trust Game (MTG). On each round, participants, who played as investors, were required to maximize their benefits by updating their prior expectations (the partner's positive or negative reputation), based on the partner's directed reciprocity, and adjusting their own investment decisions accordingly. Results showed that reputational priors strongly oriented the initial decision to trust, operationalized as the amount of investment the investor shares with the counterpart. However, while typically developed participants were mainly affected by the direct reciprocity, and rapidly adopted the optimal Tit-for-Tat strategy, participants with ASD continued to rely on reputational priors throughout the game, even when experience of the counterpart's actual behavior contradicted their prior-based expectations. In participants with ASD, the effect of the reputational prior never disappeared, and affected judgments of trustworthiness and reciprocity of the partner even after completion of the game. Moreover, the weight of prior reputation positively correlated with the severity of the ASD participant's social impairments while the reciprocity score negatively correlated with the severity of repetitive and stereotyped behaviors, as measured by the Autism Diagnostic Interview-Revised (ADI-R). In line with Bayesian theoretical accounts, the present findings indicate that individuals with ASD have difficulties encoding incoming social information and using it to revise and flexibly update prior social expectations, and that this deficit might severely hinder social learning and everyday life interactions.

A reputation for success (or failure): the association of peer academic reputations with academic self-concept, effort, and performance across the upper elementary grades.

PubMed

Gest, Scott D; Rulison, Kelly L; Davidson, Alice J; Welsh, Janet A

2008-05-01

The associations between children's academic reputations among peers and their academic self-concept, effort, and performance were examined in a longitudinal study of 427 students initially enrolled in Grades 3, 4, and 5. Assessments were completed in the fall and spring of 2 consecutive school years and in the fall of a 3rd school year. Peer academic reputation (PAR) correlated moderately strongly with teacher-rated skills and changed over time as a function of grades earned at the prior assessment. Path-analytic models indicated bidirectional associations between PAR and academic self-concept, teacher-rated academic effort, and grade point average. There was little evidence that changes in self-concept mediated the association between PAR and effort and GPA or that changes in effort mediated the association between PAR and GPA. Results suggest that peers may possess unique information about classmates' academic functioning, that children's PARs are psychologically meaningful, and that these reputations may serve as a useful marker of processes that forecast future academic engagement and performance.

Reputation and its risks.

PubMed

Eccles, Robert G; Newquist, Scott C; Schatz, Roland

2007-02-01

Regulators, industry groups, consultants, and individual companies have developed elaborate guidelines over the years for assessing and managing risks in a wide range of areas, from commodity prices to natural disasters. Yet they have all but ignored reputational risk, mostly because they aren't sure how to define or measure it. That's a big problem, say the authors. Because so much market value comes from hard-to-assess intangible assets like brand equity and intellectual capital, organizations are especially vulnerable to anything that damages their reputations. Moreover, companies with strong positive reputations attract better talent and are perceived as providing more value in their products and services, which often allows them to charge a premium. Their customers are more loyal and buy broader ranges of products and services. Since the market believes that such companies will deliver sustained earnings and future growth, they have higher price-earnings multiples and market values and lower costs of capital. Most companies, however, do an inadequate job of managing their reputations in general and the risks to their reputations in particular. They tend to focus their energies on handling the threats to their reputations that have already surfaced. That is not risk management; it is crisis management--a reactive approach aimed at limiting the damage. The authors provide a framework for actively managing reputational risk. They introduce three factors (the reputation-reality gap, changing beliefs and expectations, and weak internal coordination) that affect the level of such risks and then explore several ways to sufficiently quantify and control those factors. The process outlined in this article will help managers do a better job of assessing existing and potential threats to their companies' reputations and deciding whether to accept a particular risk or take actions to avoid or mitigate it.

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.

The influence of social preferences and reputational concerns on intergroup prosocial behaviour in gains and losses contexts

PubMed Central

Faber, Nadira S.

2015-01-01

To what extent do people help ingroup members based on a social preference to improve ingroup members’ outcomes, versus strategic concerns about preserving their reputation within their group? And do these motives manifest differently when a prosocial behaviour occurs in the context of helping another gain a positive outcome (study 1), versus helping another to avoid losing a positive outcome (study 2)? In both contexts, we find that participants are more prosocial towards ingroup (versus outgroup members) and more prosocial when decisions are public (versus private) but find no interaction between group membership and either anonymity of the decision or expected economic value of helping. Therefore, consistent with a preference-based account of ingroup favouritism, people appear to prefer to help ingroup members more than outgroup members, regardless of whether helping can improve their reputation within their group. Moreover, this preference to help ingroup members appears to take the form of an intuitive social heuristic to help ingroup members, regardless of the economic incentives or possibility of reputation management. Theoretical and practical implications for the study of intergroup prosocial behaviour are discussed. PMID:27019739

Ranking Surgical Residency Programs: Reputation Survey or Outcomes Measures?

PubMed

Wilson, Adam B; Torbeck, Laura J; Dunnington, Gary L

2015-01-01

The release of general surgery residency program rankings by Doximity and U.S. News & World Report accentuates the need to define and establish measurable standards of program quality. This study evaluated the extent to which program rankings based solely on peer nominations correlated with familiar program outcomes measures. Publicly available data were collected for all 254 general surgery residency programs. To generate a rudimentary outcomes-based program ranking, surgery programs were rank-ordered according to an average percentile rank that was calculated using board pass rates and the prevalence of alumni publications. A Kendall τ-b rank correlation computed the linear association between program rankings based on reputation alone and those derived from outcomes measures to validate whether reputation was a reasonable surrogate for globally judging program quality. For the 218 programs with complete data eligible for analysis, the mean board pass rate was 72% with a standard deviation of 14%. A total of 60 programs were placed in the 75th percentile or above for the number of publications authored by program alumni. The correlational analysis reported a significant correlation of 0.428, indicating only a moderate association between programs ranked by outcomes measures and those ranked according to reputation. Seventeen programs that were ranked in the top 30 according to reputation were also ranked in the top 30 based on outcomes measures. This study suggests that reputation alone does not fully capture a representative snapshot of a program's quality. Rather, the use of multiple quantifiable indicators and attributes unique to programs ought to be given more consideration when assigning ranks to denote program quality. It is advised that the interpretation and subsequent use of program rankings be met with caution until further studies can rigorously demonstrate best practices for awarding program standings.

Harnessing the power of reputation: strengths and limits for promoting cooperative behaviors.

PubMed

Barclay, Pat

2012-12-20

Evolutionary approaches have done much to identify the pressures that select for cooperative sentiment. This helps us understand when and why cooperation will arise, and applied research shows how these pressures can be harnessed to promote various types of cooperation. In particular, recent evidence shows how opportunities to acquire a good reputation can promote cooperation in laboratory and applied settings. Cooperation can be promoted by tapping into forces like indirect reciprocity, costly signaling, and competitive altruism. When individuals help others, they receive reputational benefits (or avoid reputational costs), and this gives people an incentive to help. Such findings can be applied to promote many kinds of helping and cooperation, including charitable donations, tax compliance, sustainable and pro-environmental behaviors, risky heroism, and more. Despite the potential advantages of using reputation to promote positive behaviors, there are several risks and limits. Under some circumstances, opportunities for reputation will be ineffective or promote harmful behaviors. By better understanding the dynamics of reputation and the circumstances under which cooperation can evolve, we can better design social systems to increase the rate of cooperation and reduce conflict.

Abu-Serriah, M; Wong, L; Dhariwal, D; Banks, R J

2014-02-01

The Internet is a powerful method of acquiring and sharing information. In marketing and business, online visibility is vital for publicity and the reputation of an organisation. To our knowledge, the importance of such visibility in medicine in general, and in Oral and Maxillofacial Surgery (OMFS) services in the UK, has not previously been investigated. We aimed to provide a better understanding of the way that patients use the Internet by asking 450 patients to complete a questionnaire when they attended outpatient OMFS departments at 2 centres. We also assessed the online visibility of the British Association of Oral and Maxillofacial Surgeons (BAOMS) and investigated the correlation between the strength of online visibility and professional reputation. Results from the self-administered, anonymous, validated questionnaires showed that 82% of patients agreed that the Internet was a powerful source of information, and two-thirds associated online visibility with a good reputation. However, the perceived online visibility of the BAOMS was poor (2%). This study mirrors findings in business publications, and confirms the link between online visibility and professional reputation. It also shows that there is a gap between patients' perceptions and the level of uptake of professional resources. We propose various strategies to bridge this gap and to promote the online visibility and professional reputation of the BAOMS and of OMFS services in the UK.

Own-Group Face Recognition Bias: The Effects of Location and Reputation

Yan, Linlin; Wang, Zhe; Huang, Jianling; Sun, Yu-Hao P.; Judges, Rebecca A.; Xiao, Naiqi G.; Lee, Kang

2017-01-01

In the present study, we examined whether social categorization based on university affiliation can induce an advantage in recognizing faces. Moreover, we investigated how the reputation or location of the university affected face recognition performance using an old/new paradigm. We assigned five different university labels to the faces: participants’ own university and four other universities. Among the four other university labels, we manipulated the academic reputation and geographical location of these universities relative to the participants’ own university. The results showed that an own-group face recognition bias emerged for faces with own-university labels comparing to those with other-university labels. Furthermore, we found a robust own-group face recognition bias only when the other university was located in a different city far away from participants’ own university. Interestingly, we failed to find the influence of university reputation on own-group face recognition bias. These results suggest that categorizing a face as a member of one’s own university is sufficient to enhance recognition accuracy and the location will play a more important role in the effect of social categorization on face recognition than reputation. The results provide insight into the role of motivational factors underlying the university membership in face perception. PMID:29066989

Reputation offsets trust judgments based on social biases among Airbnb users.

Abrahao, Bruno; Parigi, Paolo; Gupta, Alok; Cook, Karen S

2017-09-12

To provide social exchange on a global level, sharing-economy companies leverage interpersonal trust between their members on a scale unimaginable even a few years ago. A challenge to this mission is the presence of social biases among a large heterogeneous and independent population of users, a factor that hinders the growth of these services. We investigate whether and to what extent a sharing-economy platform can design artificially engineered features, such as reputation systems, to override people's natural tendency to base judgments of trustworthiness on social biases. We focus on the common tendency to trust others who are similar (i.e., homophily) as a source of bias. We test this argument through an online experiment with 8,906 users of Airbnb, a leading hospitality company in the sharing economy. The experiment is based on an interpersonal investment game, in which we vary the characteristics of recipients to study trust through the interplay between homophily and reputation. Our findings show that reputation systems can significantly increase the trust between dissimilar users and that risk aversion has an inverse relationship with trust given high reputation. We also present evidence that our experimental findings are confirmed by analyses of 1 million actual hospitality interactions among users of Airbnb.

Cooperation Survives and Cheating Pays in a Dynamic Network Structure with Unreliable Reputation

NASA Astrophysics Data System (ADS)

Antonioni, Alberto; Sánchez, Angel; Tomassini, Marco

2016-06-01

In a networked society like ours, reputation is an indispensable tool to guide decisions about social or economic interactions with individuals otherwise unknown. Usually, information about prospective counterparts is incomplete, often being limited to an average success rate. Uncertainty on reputation is further increased by fraud, which is increasingly becoming a cause of concern. To address these issues, we have designed an experiment based on the Prisoner’s Dilemma as a model for social interactions. Participants could spend money to have their observable cooperativeness increased. We find that the aggregate cooperation level is practically unchanged, i.e., global behavior does not seem to be affected by unreliable reputations. However, at the individual level we find two distinct types of behavior, one of reliable subjects and one of cheaters, where the latter artificially fake their reputation in almost every interaction. Cheaters end up being better off than honest individuals, who not only keep their true reputation but are also more cooperative. In practice, this results in honest subjects paying the costs of fraud as cheaters earn the same as in a truthful environment. These findings point to the importance of ensuring the truthfulness of reputation for a more equitable and fair society.

Hitting and missing targets by ambulance services for emergency calls: effects of different systems of performance measurement within the UK

PubMed Central

Bevan, Gwyn; Hamblin, Richard

2009-01-01

Following devolution, differences developed between UK countries in systems of measuring performance against a common target that ambulance services ought to respond to 75% of calls for what may be immediately life threatening emergencies (category A calls) within 8 minutes. Only in England was this target integral to a ranking system of ‘star rating’, which inflicted reputational damage on services that failed to hit targets, and only in England has this target been met. In other countries, the target has been missed by such large margins that services would have been publicly reported as failing, if they had been covered by the English system of star ratings. The paper argues that this case-study adds to evidence from comparisons of different systems of hospital performance measurement that, to have an effect, these systems need to be designed to inflict reputational damage on those that have performed poorly; and it explores implications of this hypothesis. The paper also asks questions about the adequacy of systems of performance measurement of ambulance services in UK countries. PMID:19381327

Comparing writing style feature-based classification methods for estimating user reputations in social media.

PubMed

Suh, Jong Hwan

2016-01-01

In recent years, the anonymous nature of the Internet has made it difficult to detect manipulated user reputations in social media, as well as to ensure the qualities of users and their posts. To deal with this, this study designs and examines an automatic approach that adopts writing style features to estimate user reputations in social media. Under varying ways of defining Good and Bad classes of user reputations based on the collected data, it evaluates the classification performance of the state-of-art methods: four writing style features, i.e. lexical, syntactic, structural, and content-specific, and eight classification techniques, i.e. four base learners-C4.5, Neural Network (NN), Support Vector Machine (SVM), and Naïve Bayes (NB)-and four Random Subspace (RS) ensemble methods based on the four base learners. When South Korea's Web forum, Daum Agora, was selected as a test bed, the experimental results show that the configuration of the full feature set containing content-specific features and RS-SVM combining RS and SVM gives the best accuracy for classification if the test bed poster reputations are segmented strictly into Good and Bad classes by portfolio approach. Pairwise t tests on accuracy confirm two expectations coming from the literature reviews: first, the feature set adding content-specific features outperform the others; second, ensemble learning methods are more viable than base learners. Moreover, among the four ways on defining the classes of user reputations, i.e. like, dislike, sum, and portfolio, the results show that the portfolio approach gives the highest accuracy.

Role of generosity and forgiveness: Return to a cooperative society

Park, Hye Jin; Kim, Beom Jun; Jeong, Hyeong-Chai

2017-04-01

One's reputation in human society depends on what and how one did in the past. If the reputation of a counterpart is too bad, we often avoid interacting with the individual. We introduce a selective cooperator called the goodie, who participates in the prisoner's dilemma game dependent on the opponent's reputation, and study its role in forming a cooperative society. We observe enhanced cooperation when goodies have a small but nonzero probability of playing the game with an individual who defected in previous rounds. Our finding implies that even this small generosity of goodies can provide defectors chances of encountering the better world of cooperation, encouraging them to escape from their isolated world of selfishness.

In this work we study a modified version of the Sznajd sociophysics model. In particular we introduce reputation, a mechanism that limits the capacity of persuasion of the agents. The reputation is introduced as a score which is time-dependent, and its introduction avoid dictatorship (all spins parallel) for a wide range of parameters. The relaxation time follows a log-normal-like distribution. In addition, we show that the usual phase transition also occurs, as in the standard model, and it depends on the initial concentration of individuals following an opinion, occurring at a initial density of up spins greater than 1/2. The transition point is determined by means of a finite-size scaling analysis.

Amarilli, Fabrizio; Spreafico, Alberto

This chapter presents the Tisettanta case study, focusing on the definition of the possible innovations that ICT technologies can bring to the Italian wood-furniture industry. This sector is characterized by industrial clusters composed mainly of a few large companies with international brand reputations and a large base of SMEs that manufacture finished products or are specialized in the production of single components/processes (such as the Brianza cluster, where Tisettanta operates). In this particular business ecosystem, ICT technologies can bring relevant support and improvements to the supply chain process, where collaborations between enterprises are put into action through the exchange of business documents such as orders, order confirmation, bills of lading, invoices, etc. The analysis methodology adopted in the Tisettanta case study refers to the TEKNE Methodology of Change (see Chapter 2), which defines a framework for supporting firms in the adoption of the Internetworked Enterprise organizational paradigm.

Privacy, Liveliness and Fairness for Reputation

NASA Astrophysics Data System (ADS)

Schiffner, Stefan; Clauß, Sebastian; Steinbrecher, Sandra

In various Internet applications, reputation systems are typical means to collect experiences users make with each other. We present a reputation system that balances the security and privacy requirements of all users involed. Our system provides privacy in the form of information theoretic relationship anonymity w.r.t. users and the reputation provider. Furthermore, it preserves liveliness, i.e., all past ratings can influence the current reputation profile of a user. In addition, mutual ratings are forced to be simultaneous and self rating is prevented, which enforces fairness. What is more, without performing mock interactions - even if all users are colluding - users cannot forge ratings. As far as we know, this is the first protocol proposed that fulfills all these properties simultaneously.

Both loved and feared: third party punishers are viewed as formidable and likeable, but these reputational benefits may only be open to dominant individuals.

PubMed

Gordon, David S; Madden, Joah R; Lea, Stephen E G

2014-01-01

Third party punishment can be evolutionarily stable if there is heterogeneity in the cost of punishment or if punishers receive a reputational benefit from their actions. A dominant position might allow some individuals to punish at a lower cost than others and by doing so access these reputational benefits. Three vignette-based studies measured participants' judgements of a third party punisher in comparison to those exhibiting other aggressive/dominant behaviours (Study 1), when there was variation in the success of punishment (Study 2), and variation in the status of the punisher and the type of punishment used (Study 3). Third party punishers were judged to be more likeable than (but equally dominant as) those who engaged in other types of dominant behaviour (Study 1), were judged to be equally likeable and dominant whether their intervention succeeded or failed (Study 2), and participants believed that only a dominant punisher could intervene successfully (regardless of whether punishment was violent or non-violent) and that subordinate punishers would face a higher risk of retaliation (Study 3). The results suggest that dominance can dramatically reduce the cost of punishment, and that while individuals can gain a great deal of reputational benefit from engaging in third party punishment, these benefits are only open to dominant individuals. Taking the status of punishers into account may therefore help explain the evolution of third party punishment.

This article deals with the impact of malicious servers over different trust and reputation models in wireless sensor networks. First, we analysed the five trust and reputation models, namely BTRM-WSN, Eigen trust, peer trust, power trust, linguistic fuzzy trust model. Further, we proposed wireless sensor network design for optimisation of these models. Finally, influence of malicious servers on the behaviour of above mentioned trust and reputation models is discussed. Statistical analysis has been carried out to prove the validity of our proposal.

Neural methods based on modified reputation rules for detection and identification of intrusion attacks in wireless ad hoc sensor networks

NASA Astrophysics Data System (ADS)

Hortos, William S.

2010-04-01

Determining methods to secure the process of data fusion against attacks by compromised nodes in wireless sensor networks (WSNs) and to quantify the uncertainty that may exist in the aggregation results is a critical issue in mitigating the effects of intrusion attacks. Published research has introduced the concept of the trustworthiness (reputation) of a single sensor node. Reputation is evaluated using an information-theoretic concept, the Kullback- Leibler (KL) distance. Reputation is added to the set of security features. In data aggregation, an opinion, a metric of the degree of belief, is generated to represent the uncertainty in the aggregation result. As aggregate information is disseminated along routes to the sink node(s), its corresponding opinion is propagated and regulated by Josang's belief model. By applying subjective logic on the opinion to manage trust propagation, the uncertainty inherent in aggregation results can be quantified for use in decision making. The concepts of reputation and opinion are modified to allow their application to a class of dynamic WSNs. Using reputation as a factor in determining interim aggregate information is equivalent to implementation of a reputation-based security filter at each processing stage of data fusion, thereby improving the intrusion detection and identification results based on unsupervised techniques. In particular, the reputation-based version of the probabilistic neural network (PNN) learns the signature of normal network traffic with the random probability weights normally used in the PNN replaced by the trust-based quantified reputations of sensor data or subsequent aggregation results generated by the sequential implementation of a version of Josang's belief model. A two-stage, intrusion detection and identification algorithm is implemented to overcome the problems of large sensor data loads and resource restrictions in WSNs. Performance of the twostage algorithm is assessed in simulations of WSN scenarios with multiple sensors at edge nodes for known intrusion attacks. Simulation results show improved robustness of the two-stage design based on reputation-based NNs to intrusion anomalies from compromised nodes and external intrusion attacks.

Reputation management: evidence for ability but reduced propensity in autism.

PubMed

Cage, Eilidh; Pellicano, Elizabeth; Shah, Punit; Bird, Geoffrey

2013-10-01

Previous research has reported that autistic adults do not manage their reputation, purportedly due to problems with theory of mind [Izuma, Matsumoto, Camerer, & Adolphs]. The current study aimed to test alternative explanations for this apparent lack of reputation management. Twenty typical and 19 autistic adults donated to charity and to a person, both when alone and when observed. In an additional manipulation, for half of the participants, the observer was also the recipient of their donations, and participants were told that this observer would subsequently have the opportunity to donate to them (motivation condition). This manipulation was designed to encourage an expectation of a reciprocal "tit-for-tat" strategy in the participant, which may motivate participants to change their behavior to receive more donations. The remaining participants were told that the person watching was just observing the procedure (no motivation condition). Our results replicated Izuma et al.'s finding that autistic adults did not donate more to charity when observed. Yet, in the motivation condition, both typical and autistic adults donated significantly more to the observer when watched, although this effect was significantly attenuated in autistic individuals. Results indicate that, while individuals with autism may have the ability to think about reputation, a reduced expectation of reciprocal behavior from others may reduce the degree to which they engage in reputation management. © 2013 International Society for Autism Research, Wiley Periodicals, Inc.

Peer-assessment of medical communication skills: the impact of students' personality, academic and social reputation on behavioural assessment.

Hulsman, Robert L; Peters, Joline F; Fabriek, Marcel

2013-09-01

Peer-assessment of communication skills may contribute to mastery of assessment criteria. When students develop the capacity to judge their peers' performance, they might improve their capacity to examine their own clinical performance. In this study peer-assessment ratings are compared to teacher-assessment ratings. The aim of this paper is to explore the impact of personality and social reputation as source of bias in assessment of communication skills. Second year students were trained and assessed history taking communication skills. Peers rated the students' personality and academic and social reputation. Peer-assessment ratings were significantly correlated with teacher-ratings in a summative assessment of medical communication. Peers did not provide negative ratings on final scales but did provide negative ratings on subcategories. Peer- and teacher-assessments were both related to the students' personality and academic reputation. Peer-assessment cannot replace teacher-assessment if the assessment should result in high-stake decisions about students. Our data do not confirm the hypothesis that peers are overly biased by personality and reputation characteristics in peer-assessment of performance. Early introduction of peer-assessment in medical education would facilitate early acceptance of this mode of evaluation and would promote early on the habit of critical evaluation of professional clinical performance and acceptance of being evaluated critically by peers.

Influences of Agents with a Self-Reputation Awareness Component in an Evolutionary Spatial IPD Game

PubMed Central

Huang, Chung-Yuan; Lee, Chun-Liang

2014-01-01

Iterated prisoner’s dilemma (IPD) researchers have shown that strong positive reputations plus an efficient reputation evaluation system encourages both sides to pursue long-term collaboration and to avoid falling into mutual defection cycles. In agent-based environments with reliable reputation rating systems, agents interested in maximizing their private interests must show concern for other agents as well as their own self-reputations–an important capability that standard IPD game agents lack. Here we present a novel learning agent model possessing self-reputation awareness. Agents in our proposed model are capable of evaluating self-behaviors based on a mix of public and private interest considerations, and of testing various solutions aimed at meeting social standards. Simulation results indicate multiple outcomes from the addition of a small percentage of self-reputation awareness agents: faster cooperation, faster movement toward stability in an agent society, a higher level of public interest in the agent society, the resolution of common conflicts between public and private interests, and a lower potential for rational individual behavior to transform into irrational group behavior.

Objective Peer victimization (PV) is a key interpersonal stressor that can be traumatizing for youth. This study evaluated the relationships between overt, relational, reputational, and cyber PV and adolescents’ somatic complaints and sleep problems. Symptoms of depression and social anxiety were examined as potential mediators. Method Adolescents (N = 1,162; M age = 15.80 years; 57% female; 80% Hispanic) were assessed at three time points, 6 weeks apart, using standardized measures of PV, depression, social anxiety, sleep problems, and somatic complaints. Structural equation modeling evaluated key study aims. Results Relational, reputational, and cyber PV, but not overt PV, were directly or indirectly associated with subsequent somatic complaints and/or sleep problems. Depression and social anxiety mediated relationships between relational PV and health outcomes, whereas reputational PV was indirectly associated with somatic complaints via depression only. Discussion The stress of PV may contribute to adolescents’ sleep problems and somatic complaints and has implications for pediatric psychologists.

Reputation Effects in Public and Private Interactions

PubMed Central

Ohtsuki, Hisashi; Iwasa, Yoh; Nowak, Martin A.

2015-01-01

We study the evolution of cooperation in a model of indirect reciprocity where people interact in public and private situations. Public interactions have a high chance to be observed by others and always affect reputation. Private interactions have a lower chance to be observed and only occasionally affect reputation. We explore all second order social norms and study conditions for evolutionary stability of action rules. We observe the competition between “honest” and “hypocritical” strategies. The former cooperate both in public and in private. The later cooperate in public, where many others are watching, but try to get away with defection in private situations. The hypocritical idea is that in private situations it does not pay-off to cooperate, because there is a good chance that nobody will notice it. We find simple and intuitive conditions for the evolution of honest strategies. PMID:26606239

Cultures of Trust: Effects of Avatar Faces and Reputation Scores on German and Arab Players in an Online Trust-Game

2014-01-01

Reputation systems as well as seller depictions (photos; avatars) have been shown to reduce buyer uncertainty and to foster trust in online trading. With the emergence of globalized e-markets, it remains an urgent question whether these mechanisms, found to be effective for Western cultures, also apply to other cultures. Hypothesizing that members of collectivistic cultures in contrast to those of individualistic cultures would rely more on visual social cues (seller faces) than on factual information (reputation scores), we compared buying decisions of Arab and German participants in an experimental trust game. Photo-realistic avatars were used instead of photos to control facial features and expressions. The results revealed significant main effects for both reputation scores and avatar faces. Moreover, both variables significantly affected the purchase behavior of Arab as well as German buyers, suggesting cross-cultural universals in the processing of trust cues. The results have implications for future cross-cultural studies in e-commerce as well as the design of online markets and shared virtual environments. PMID:24901696

Identifying online user reputation is significant for online social systems. In this paper, taking into account the preference physics of online user collective behaviors, we present an improved group-based rating method for ranking online user reputation based on the user preference (PGR). All the ratings given by each specific user are mapped to the same rating criteria. By grouping users according to their mapped ratings, the online user reputation is calculated based on the corresponding group sizes. Results for MovieLens and Netflix data sets show that the AUC values of the PGR method can reach 0.9842 (0.9493) and 0.9995 (0.9987) for malicious (random) spammers, respectively, outperforming the results generated by the traditional group-based method, which indicates that the online preference plays an important role for measuring user reputation.

Toward a theory of leadership and state building.

2011-12-27

We present a theory of the state based on political leadership and reputational equilibria. A political leader first needs a reputation for reliably rewarding loyal supporters. Reputational expectations between political leaders and their supporters become the fundamental political laws on which the enforcement of all other constitutional laws may be based. Successful democratic development requires a plentiful supply of leaders who have good reputations for using public funds responsibly to serve the public at large and not just giving jobs to their active supporters. It is argued that decentralized democracy may be the best way to improve the chances for successful democracy.

Shaw, Alex; Olson, Kristina

2015-05-01

Six-year-old children negatively evaluate plagiarizers just as adults do (Olson & Shaw, 2011), but why do they dislike plagiarizers? Children may think plagiarism is wrong because plagiarizing negatively impacts other people's reputations. We investigated this possibility by having 6- to 9-year-old children evaluate people who shared their own or other people's ideas (stories). In Experiment 1, we found that children consider it acceptable to retell someone else's story if the source is given credit for their story (improving the source's reputation), but not if the reteller claims credit for the story (steals credit away from someone else). Experiments 2 and 3 showed that children do not consider it bad to lie by giving someone else credit for one's own good story (improving someone else's reputation), but do consider it bad to give someone else credit for one's own bad story (improving one's own reputation at the expense of someone else's). Experiment 4 demonstrated that children think it is equally bad to take credit for someone else's idea for oneself as it is to take someone else's idea and give credit to someone else, suggesting that children dislike when others take credit away from someone else, regardless of whether or not it improves the plagiarizer's reputation. Our results suggest that children dislike plagiarism because it negatively affects others' reputations by taking credit away from them. © 2014 John Wiley & Sons Ltd.

A Collaborator's Reputation Can Bias Decisions and Anxiety under Uncertainty.

Qi, Song; Footer, Owen; Camerer, Colin F; Mobbs, Dean

2018-02-28

Informational social influence theory posits that under conditions of uncertainty, we are inclined to look to others for advice. This leaves us remarkably vulnerable to being influenced by others' opinions or advice. Rational agents, however, do not blindly seek and act on arbitrary information, but often consider the quality of its source before committing to a course of action. Here, we ask the question of whether a collaborator's reputation can increase their social influence and, in turn, bias perception and anxiety under changing levels of uncertainty. Human male and female participants were asked to provide estimations of dot direction using the random dot motion (RDM) perceptual discrimination task and were paired with transient collaborators of high or low reputation whom provided their own estimations. The RDM varied in degrees of uncertainty and joint performance accuracy was linked to risk of an electric shock. Despite providing identical information, we show that collaborating with a high reputation compared with a low reputation partner, led to significantly more conformity during the RDM task for uncertain perceptual decisions. Consequently, high reputation partners decreased the subjects' anxiety during the anticipatory shock periods. fMRI data showed that parametric changes in conformity resulted in increased activity in the ventromedial PFC, whereas dissent was associated with increased in activity in the dorsal anterior cingulate cortex (dACC). Furthermore, the dACC and insula, regions involved in anticipatory pain, were significantly more active when collaborating with a low reputation partner. These results suggest that information about reputation can influence both cognitive and affective processes and in turn alter the neural circuits that underlie decision-making and emotion. SIGNIFICANCE STATEMENT Humans look to others for advice when making decisions under uncertainty.

Here, we ask the question of whether a collaborators' reputation can increase social influence and in turn bias perception and anxiety in the context of perceptual uncertainty.

Furthermore, our results show that information about reputation alters the neural circuits that underlie decision-making and emotion. Copyright © 2018 the authors 0270-6474/18/382262-08$15.00/0.

Ranking online quality and reputation via the user activity

How to design an accurate algorithm for ranking the object quality and user reputation is of importance for online rating systems. In this paper we present an improved iterative algorithm for online ranking object quality and user reputation in terms of the user degree (IRUA), where the user's reputation is measured by his/her rating vector, the corresponding objects' quality vector and the user degree. The experimental results for the empirical networks show that the AUC values of the IRUA algorithm can reach 0.9065 and 0.8705 in Movielens and Netflix data sets, respectively, which is better than the results generated by the traditional iterative ranking methods. Meanwhile, the results for the synthetic networks indicate that user degree should be considered in real rating systems due to users' rating behaviors. Moreover, we find that enhancing or reducing the influences of the large-degree users could produce more accurate reputation ranking lists.

Aberrant reward center response to partner reputation during a social exchange game in generalized social phobia.

Generalized social anxiety disorder (GSAD) is characterized by excessive fear of public scrutiny and reticence in social engagement. Previous studies have probed the neural basis of GSAD often using static, noninteractive stimuli (e.g., face photographs) and have identified dysfunction in fear circuitry. We sought to investigate brain-based dysfunction in GSAD during more real-world, dynamic social interactions, focusing on the role of reward-related regions that are implicated in social decision-making. Thirty-six healthy individuals (healthy control [HC]) and 36 individuals with GSAD underwent functional magnetic resonance imaging (fMRI) scanning while participating in a behavioral economic game ("Trust Game") involving iterative exchanges with fictive partners who acquire differential reputations for reciprocity. We investigated brain responses to reciprocation of trust in one's social partner, and how these brain responses are modulated by partner reputation for repayment. In both HC and GSAD, receipt of reciprocity robustly engaged ventral striatum, a region implicated in reward. In HC, striatal responses to reciprocity were specific to partners who have consistently returned the investment ("cooperative partners"), and were absent for partners who lack a cooperative reputation. In GSAD, modulation of striatal responses by partner reputation was absent. Social anxiety severity predicted diminished responses to cooperative partners. These results suggest abnormalities in GSAD in reward-related striatal mechanisms that may be important for the initiation, valuation, and maintenance of cooperative social relationships. Moreover, this study demonstrates that dynamic, interactive task paradigms derived from economics can help illuminate novel mechanisms of pathology in psychiatric illnesses in which social dysfunction is a cardinal feature. © 2013 Wiley Periodicals, Inc.

Donors to charity gain in both indirect reciprocity and political reputation.

Darwinian evolution can explain human cooperative behaviour among non-kin by either direct or indirect reciprocity. In the latter case one does not expect a return for an altruistic act from the recipient as with direct reciprocity, but from another member of the social group. However, the widespread human behaviour of donating to poor people outside the social group, for example, to charity organizations, that are unlikely to reciprocate indirectly and thus are equivalent to defectors in the game is still an evolutionary puzzle. Here we show experimentally that donations made in public to a well-known relief organization resulted both in increased income (that the donors received from the members of their group) and in enhanced political reputation (they were elected to represent the interests of their group). Donations may thus function as an honest signal for one's social reliability. PMID:12028769

The evolution of reputation-based partner-switching behaviors with a cost

2014-01-01

Humans constantly adjust their social relationships and choose new partners of good reputations, thereby promoting the evolution of cooperation. Individuals have to pay a cost to build a reputation, obtain others' information and then make partnership adjustments, yet the conditions under which such costly behaviors are able to evolve remain to be explored. In this model, I assume that individuals have to pay a cost to adjust their partnerships. Furthermore, whether an individual can adjust his partnership based on reputation is determined by his strategic preference, which is updated via coevolution. Using the metaphor of a public goods game where the collective benefit is shared among all members of a group, the coupling dynamics of cooperation and partnership adjustment were numerically simulated. Partner-switching behavior cannot evolve in a public goods game with a low amplification factor. However, such an effect can be exempted by raising the productivity of public goods or the frequency of partnership adjustment. Moreover, costly partner-switching behavior is remarkably promoted by the condition that the mechanism of reputation evaluation considers its prosociality. A mechanism of reputation evaluation that praises both cooperative and partner-switching behaviors allows them to coevolve. PMID:25091006

Reputation-Based Secure Sensor Localization in Wireless Sensor Networks

Location information of sensor nodes in wireless sensor networks (WSNs) is very important, for it makes information that is collected and reported by the sensor nodes spatially meaningful for applications. Since most current sensor localization schemes rely on location information that is provided by beacon nodes for the regular sensor nodes to locate themselves, the accuracy of localization depends on the accuracy of location information from the beacon nodes. Therefore, the security and reliability of the beacon nodes become critical in the localization of regular sensor nodes. In this paper, we propose a reputation-based security scheme for sensor localization to improve the security and the accuracy of sensor localization in hostile or untrusted environments. In our proposed scheme, the reputation of each beacon node is evaluated based on a reputation evaluation model so that regular sensor nodes can get credible location information from highly reputable beacon nodes to accomplish localization. We also perform a set of simulation experiments to demonstrate the effectiveness of the proposed reputation-based security scheme. And our simulation results show that the proposed security scheme can enhance the security and, hence, improve the accuracy of sensor localization in hostile or untrusted environments. PMID:24982940

Gender differences in cooperative choices and their neural correlates were investigated in a situation where reputation represented a crucial issue. Males and females were involved in an economic exchange (trust game) where economic and reputational payoffs had to be balanced in order to increase personal welfare. At the behavioral level, females showed a stronger reaction to negative reputation judgments that led to higher cooperation than males, measured by back transfers in the game. The neuroanatomical counterpart of this gender difference was found within the reward network (engaged in producing expectations of positive results) and reputation-related brain networks, such as the self-control network (engaged in strategically resisting the temptation to defect) and the mentalizing network (engaged in thinking about how one is viewed by others), in which the dorsolateral prefrontal cortex (DLPFC) and the medial (M)PFC respectively play a crucial role. Furthermore, both DLPFC and MPFC activity correlated with the amount of back transfer, as well as with the personality dimensions assessed with the Big-Five Questionnaire (BFQ-2). Males, according to their greater DLPFC recruitment and their higher level of the BFQ-2 subscale of Dominance, were more focused on implementing a profit-maximizing strategy, pursuing this target irrespectively of others' judgments. On the contrary, females, according to their greater MPFC activity and their lower level of Dominance, were more focused on the reputation per se and not on the strategic component of reputation building. These findings shed light on the sexual dimorphism related to cooperative behavior and its neural correlates.

To analyze the association between US urology department Twitter presence and U.S. News and World Report (USNWR) reputation scores, to examine the content, informational value, and intended audience of these platforms, and to identify objectives for Twitter use. We identified Twitter accounts for urology departments scored in the 2016-2017 USNWR. Correlation coefficients were calculated between Twitter metrics (number of followers, following, tweets, and Klout influence scores) with USNWR reputation scores. We also performed a detailed content analysis of urology department tweets during a 6-month period to characterize the content. Finally, we distributed a survey to the urology department accounts via Twitter, inquiring who administers the content, and their objectives for Twitter use. Among 42 scored urology departments with Twitter accounts, the median number of followers, following, and tweets were 337, 193, and 115, respectively. All of these Twitter metrics had a statistically significant positive correlation with reputation scores (P <.05). Content analyses revealed that most tweets were about conferences, education, and publications, targeting the general public or urologic community. Survey results revealed that the primary reason for twitter use among urology departments was visibility and reputation, and urologists are considered the most important target audience. There is statistically significant correlation between Twitter activity and USNWR reputation scores for urology departments. Our results suggest that Twitter provides a novel mechanism for urology departments to communicate about academic and educational topics, and social media engagement can enhance reputation.

Insensitivity to social reputation in autism

Izuma, Keise; Matsumoto, Kenji; Camerer, Colin F.; Adolphs, Ralph

2011-01-01

People act more prosocially when they know they are watched by others, an everyday observation borne out by studies from behavioral economics, social psychology, and cognitive neuroscience. This effect is thought to be mediated by the incentive to improve one's social reputation, a specific and possibly uniquely human motivation that depends on our ability to represent what other people think of us. Here we tested the hypothesis that social reputation effects are selectively impaired in autism, a developmental disorder characterized in part by impairments in reciprocal social interactions but whose underlying cognitive causes remain elusive. When asked to make real charitable donations in the presence or absence of an observer, matched healthy controls donated significantly more in the observer's presence than absence, replicating prior work. By contrast, people with high-functioning autism were not influenced by the presence of an observer at all in this task. However, both groups performed significantly better on a continuous performance task in the presence of an observer, suggesting intact general social facilitation in autism. The results argue that people with autism lack the ability to take into consideration what others think of them and provide further support for specialized neural systems mediating the effects of social reputation.

Reputation can promote cooperation in public goods game and player's cooperative behavior is not pure economical rationality, but habituation would influence their behaviors as well. One's habituation can be formed by repeated behaviors in daily life and be affected by habitual preference. We aim to investigate the sustainable cooperation based on reputation and habit formation. To better investigate the impacts of reputation and habitual preference on the evolution and sustainability of cooperation. We introduce three types of agents into our spatial public goods game. Through numerical simulations, we find that the larger habitual preference make cooperation easier to emerge and maintain. Additionally, we find that a moderate number of agents who want to obtain more reputation (ICs) are best for the sustainability of cooperation. Finally, we observe that the variation of donations of ICs can influence greatly on the equilibrium of public goods game. When ICs reduce their donations, a proper contribution will be better to maintain the cooperative behaviors. Copyright © 2017 Elsevier B.V. All rights reserved.

The effects of social identity threat and social identity affirmation on laypersons' perception of scientists.

PubMed

Nauroth, Peter; Gollwitzer, Mario; Kozuchowski, Henrik; Bender, Jens; Rothmund, Tobias

2017-10-01

Public debates about socio-scientific issues (e.g. climate change or violent video games) are often accompanied by attacks on the reputation of the involved scientists. Drawing on the social identity approach, we report a minimal group experiment investigating the conditions under which scientists are perceived as non-prototypical, non-reputable, and incompetent. Results show that in-group affirming and threatening scientific findings (compared to a control condition) both alter laypersons' evaluations of the study: in-group affirming findings lead to more positive and in-group threatening findings to more negative evaluations. However, only in-group threatening findings alter laypersons' perceptions of the scientists who published the study: scientists were perceived as less prototypical, less reputable, and less competent when their research results imply a threat to participants' social identity compared to a non-threat condition. Our findings add to the literature on science reception research and have implications for understanding the public engagement with science.

Reputation, Princing and the E-Science Grid

Anandasivam, Arun; Neumann, Dirk

One of the fundamental aspects for an efficient Grid usage is the optimization of resource allocation among the participants. However, this has not yet materialized. Each user is a self-interested participant trying to maximize his utility whereas the utility is not only determined by the fastest completion time, but on the prices as well. Future revenues are influenced by users' reputation. Reputation mechanisms help to build trust between loosely coupled and geographically distributed participants. Providers need an incentive to reduce selfish cancellation of jobs and privilege own jobs. In this chapter we present first an offline scheduling mechanism with a fixed price. Jobs are collected by a broker and scheduled to machines. The goal of the broker is to balance the load and to maximize the revenue in the network. Consumers can submit their jobs according to their preferences, but taking the incentives of the broker into account. This mechanism does not consider reputation. In a second step a reputation-based pricing mechanism for a simple, but fair pricing of resources is analyzed. In e-Science researchers do not appreciate idiosyncratic pricing strategies and policies. Their interest lies in doing research in an efficient manner. Consequently, in our mechanism the price is tightly coupled to the reputation of a site to guarantee fairness of pricing and facilitate price determination. Furthermore, the price is not the only parameter as completion time plays an important role, when deadlines have to be met. We provide a flexible utility and decision model for every participant and analyze the outcome of our reputation-based pricing system via simulation.

Gender differences in cooperative choices and their neural correlates were investigated in a situation where reputation represented a crucial issue. Males and females were involved in an economic exchange (trust game) where economic and reputational payoffs had to be balanced in order to increase personal welfare. At the behavioral level, females showed a stronger reaction to negative reputation judgments that led to higher cooperation than males, measured by back transfers in the game. The neuroanatomical counterpart of this gender difference was found within the reward network (engaged in producing expectations of positive results) and reputation-related brain networks, such as the self-control network (engaged in strategically resisting the temptation to defect) and the mentalizing network (engaged in thinking about how one is viewed by others), in which the dorsolateral prefrontal cortex (DLPFC) and the medial (M)PFC respectively play a crucial role. Furthermore, both DLPFC and MPFC activity correlated with the amount of back transfer, as well as with the personality dimensions assessed with the Big-Five Questionnaire (BFQ-2). Males, according to their greater DLPFC recruitment and their higher level of the BFQ-2 subscale of Dominance, were more focused on implementing a profit-maximizing strategy, pursuing this target irrespectively of others' judgments. On the contrary, females, according to their greater MPFC activity and their lower level of Dominance, were more focused on the reputation per se and not on the strategic component of reputation building. These findings shed light on the sexual dimorphism related to cooperative behavior and its neural correlates. PMID:25180581

In the conditions of dynamic innovative development of the enterprises of transport branch along with maintaining economic instability it has become necessary to consider not only traditional factors at assessment of efficiency of activity and cost of business, but also consider business reputation factor, which depends on the level of innovative development of the enterprise and generates effect of synergy. Paper considers the concept of synergistic effect. Classification of types of synergistic effects is cited. Estimation procedure for influence of the technical level and innovative development of transport enterprises on the value of business reputation is considered. Functional dependence of the cost of business reputation on the innovative development and synergistic effect is defined.

Factors influencing intentions to use social recommender systems: a social exchange perspective.

PubMed

Chang, Tsung-Sheng; Hsiao, Wei-Hung

2013-05-01

This study employs the perspective of social exchange theory and seeks to understand users' intentions to use social recommender systems (SRS) through three psychological factors: trust, shared values, and reputation. We use structural equation modeling to analyze 221 valid questionnaires. The results show that trust has a direct positive influence on the intention to use SRS, followed by shared values, whereas reputation has an indirect influence on SRS use. We further discuss specific recommendations concerning these factors for developing SRS.

Which is feared more: harm to the ego or financial peril? A survey of anesthesiologists' attitudes about medical malpractice.

PubMed

Burkle, Christopher M; Martin, David P; Keegan, Mark T

2012-09-01

This article reports the results of a study of anesthesiologists to assess their concerns regarding medical malpractice liability risk. Specifically, it explored whether their fears stem more from being named as a party to a suit or from the financial impact of damage awards. According to the respondents, their reputation among patients and colleagues is of greater concern than the financial impact of a malpractice suit. Forty-six percent of the 149 respondents reported a constant fear of malpractice risk; 43% were concerned about their reputation among colleagues and 57% feared their reputation would be compromised among patients. A large majority voiced concern about potential inclusion in the National Practitioner Data Bank (83%) and their rankings on online physician-grading sites (85%). Forty-one percent said financial consequences were a concern, and 54% indicated that obtaining affordable liability coverage was an issue.

[How are consumers, service and market factors related to customer loyalty in medical service? Targeting the medical consumer in a city].

PubMed

Lee, Sunhee; Kim, Hyunmi; Kim, Juhye; Ha, Gwiyeom

2008-09-01

This study was performed to explore customer loyalty and the related factors. 900 households (a 1% sample) were randomly selected from the total population of K city located in Kangwon province. An interview survey was performed with using a structured questionnaire for the subjects (923 persons) who had used medical service during the year before the survey, and the survey was done September, 2002. When comparing the relating factors related with customer loyalty according to the sociodemographic characteristics, the older group showed a significantly higher level of recognition for service quality, service reputation, internal customers.attitudes and switching cost. The lower income group showed a higher level of recognition for service quality, service image and switching cost. The lower educated group showed a higher level of recognition for service reputation, service image and internal customers.attitudes. The higher educated group showed a higher level of recognition for perceived risk, and seeking variety. In addition, the expert group or the service and manufacturing workers group showed a higher level of recognition for service involvement. On multiple regression analysis, internal customers' attitudes, service image, service reputation, service quality, switching cost, and substitutability showed significant relations with customer loyalty. This study showed that customer loyalty was significantly influenced by service factors like internal customers' attitudes, service image, service reputation, and service quality, and by market factors like switching cost, and substitutability. The results of this study can be used as a baseline for developing strategies to create and keep customers with high loyalty.

Development and Validation of the Masculine Attributes Questionnaire

2017-01-01

The present study describes the development and validation of the Masculine Attributes Questionnaire (MAQ). The purpose of this study was to develop a theoretically and empirically grounded measure of masculine attributes for sexual health research with African American young men. Consistent with Whitehead’s theory, the MAQ items were hypothesized to comprise two components representing reputation-based and respect-based attributes. The sample included 505 African American men aged 19 to 22 years (M = 20.29, SD = 1.10) living in resource-poor communities in the rural South. Convergent and discriminant validity of the MAQ were assessed by examining the associations of masculinity attributes with psychosocial factors. Criterion validity was assessed by examining the extent to which the MAQ subscales predicted sexual risk behavior outcomes. Consistent with study hypotheses, the MAQ was composed of (a) reputation-based attributes oriented toward sexual prowess, toughness, and authority-defying behavior and (b) respect-based attributes oriented toward economic independence, socially approved levels of hard work and education, and committed romantic relationships. Reputation-based attributes were associated positively with street code and negatively related to academic orientation, vocational engagement, and self-regulation, whereas respect-based attributes were associated positively with academic and vocational orientations and self-regulation. Finally, reputation-based attributes predicted sexual risk behaviors including concurrent sexual partnerships, multiple sexual partners, marijuana use, and incarceration, net of the influence of respect-based attributes. The development of the MAQ provides a new measure that permits systematic quantitative investigation of the associations between African American men’s masculinity ideology and sexual risk behavior.

Shuhud, Mohd Ilias M.; Alwi, Najwa Hayaati Md; Halim, Azni Haslizan Abd

2018-05-01

Online reputation is an invaluable asset for modern organizations as it can help in business performance especially in sales and profit. However, if we are not aware of our reputation, it is difficult to maintain it. Thus, social media analytics is a new tool that can provide online reputation monitoring in various ways such as sentiment analysis. As a result, numerous large-scale organizations have implemented Online Reputation Monitoring (ORM) systems. However, this solution is not supposed to be exclusively for high-income organizations, as many organizations regardless sizes and types are now online. This research attempts to propose an affordable and reliable ORM system using combination of open source analytics tools for both novice practitioners and academicians. We also evaluate its prediction accuracy and we discovered that the system provides acceptable predictions (sixty percent accuracy) and demonstrate a tally prediction of major polarity by human annotation. The proposed system can help in supporting business decisions with flexible monitoring strategies especially for organization that want to initiate and administrate ORM themselves at low cost.

Selecting a provider: what factors influence patients' decision making?

PubMed

Abraham, Jean; Sick, Brian; Anderson, Joseph; Berg, Andrea; Dehmer, Chad; Tufano, Amanda

2011-01-01

Each year consumers make a variety of decisions relating to their healthcare. Some experts argue that stronger consumer engagement in decisions about where to obtain medical care is an important mechanism for improving efficiency in healthcare delivery and financing. Consumers' ability and motivation to become more active decision makers are affected by several factors, including financial incentives and access to information. This study investigates the set of factors that consumers consider when selecting a provider, including attributes of the provider and the care experience and the reputation of the provider. Additionally, the study evaluates consumers awareness and use of formal sources of provider selection information. Our results from analyzing data from a survey of 467 patients at four clinics in Minnesota suggest that the factors considered of greatest importance include reputation of the physician and reputation of the healthcare organization. Contractual and logistical factors also play a role, with respondents highlighting the importance of seeing a provider affiliated with their health plan and appointment availability. Few respondents indicated that advertisements or formal sources of quality information affected their decision making. The key implication for provider organizations is to carefully manage referral sources to ensure that they consistently meet the needs of referrers. Excellent service to existing patients and to the network of referring physicians yields patient and referrer satisfaction that is critical to attracting new patients. Finally, organizations more generally may want to explore the capabilities of new media and social networking sites for building reputation.

Mira, José Joaquín; Carrillo, Irene; Lorenzo, Susana

To explore what hospitals and primary care (PC) are doing to reduce the negative social impact of a serious adverse event (AE). We surveyed 195 hospital (n=113) and PC (n=82) managers from eight autonomous communities to explore the level of implementation of five interventions recommended after an AE to protect the reputation of healthcare institutions. Most institutions (70, 45.2% PC, and 85, 54.8% hospitals) did not have a crisis plan to protect their reputation after an AE. Internal (p=0.0001) and external (p=0.012) communications were addressed better in PC than in hospitals. Very few institutions had defined the managers' role in case of an AE (10.7% hospitals versus 6.25% PC). A majority of healthcare institutions have not planned crisis intervention after an AE with severe consequences nor have they defined plans to recover citizens' trust after an AE.

Exploring the Feasibility of Reputation Models for Improving P2P Routing under Churn

NASA Astrophysics Data System (ADS)

Sànchez-Artigas, Marc; García-López, Pedro; Herrera, Blas

Reputation mechanisms help peer-to-peer (P2P) networks to detect and avoid unreliable or uncooperative peers. Recently, it has been discussed that routing protocols can be improved by conditioning routing decisions to the past behavior of forwarding peers. However, churn — the continuous process of node arrival and departure — may severely hinder the applicability of rating mechanisms. In particular, short lifetimes mean that reputations are often generated from a small number of transactions.

British American Tobacco’s partnership with Earthwatch Europe and its implications for public health

2011-01-01

This paper explores a partnership between British American Tobacco (BAT) and the environmental organisation Earthwatch Europe (EE) and considers its implications for countries implementing Article 5.3 of the World Health Organisation Framework Convention on Tobacco Control. We reviewed approximately 100 internal BAT documents, interviewed EE’s former executive director, and examined media accounts and BAT and EE websites. We analysed materials by reviewing them iteratively, identifying themes, constructing a timeline of events, and assembling a case study. BAT sought a partnership with EE to gain a global ally that could provide entrée into the larger NGO community. EE debated the ethics of working with BAT, resolving them in BAT’s favour and taking a narrow view of its own overall organizational mission. To protect its reputation, EE delayed public disclosure of the partnership. Instead, EE promoted it to policymakers and other NGOs, extending BAT’s reputation and reach into influential circles. The potential for normalising the tobacco industry presence within government through NGO partnerships, and the benefits that accrued to BAT even when the partnership was not being publicised, show why governments seeking to protect effective tobacco control policies from industry influence need to consider ways to identify and discourage “hidden” NGO partnerships.

2012-01-01

While examples of the successful use of service guarantees in health-care do exist, to-date, researchers have yet to examine this industry-specific application beyond a case study perspective. The results of this experiment begin to shed light on whether or not guarantees should be used, and if so, under what conditions are they appropriate. Respondents indicate that the thoughtful use of service guarantees can positively impact their perceptions of the health-care provider's reputation and, ultimately, their behavioral intentions towards the same provider. However, consideration must be given to the type of guarantee being offered and to whom the guarantee is targeted.

The price of being seen to be just: an intention signalling strategy for indirect reciprocity.

PubMed

Tanaka, Hiroki; Ohtsuki, Hisashi; Ohtsubo, Yohsuke

2016-07-27

Cooperation among strangers is a marked characteristic of human sociality. One prominent evolutionary explanation for this form of human cooperation is indirect reciprocity, whereby each individual selectively helps people with a 'good' reputation, but not those with a 'bad' reputation. Some evolutionary analyses have underscored the importance of second-order reputation information (the reputation of a current partner's previous partner) for indirect reciprocity as it allows players to discriminate justified 'good' defectors, who selectively deny giving help to 'bad' partners, from unjustified 'bad' defectors. Nevertheless, it is not clear whether people in fact make use of second-order information in indirect reciprocity settings. As an alternative, we propose the intention signalling strategy, whereby defectors are given the option to abandon a resource as a means of expunging their 'bad' reputation. Our model deviates from traditional modelling approaches in the indirect reciprocity literature in a crucial way-we show that first-order information is sufficient to maintain cooperation if players are given an option to signal their intention. Importantly, our model is robust against invasion by both unconditionally cooperative and uncooperative strategies, a first step towards demonstrating its viability as an evolutionarily stable strategy. Furthermore, in two behavioural experiments, when participants were given the option to abandon a resource so as to mend a tarnished reputation, participants not only spontaneously began to use this option, they also interpreted others' use of this option as a signal of cooperative intent. © 2016 The Author(s).

Spatiotemporal access model based on reputation for the sensing layer of the IoT.

PubMed

2014-01-01

Access control is a key technology in providing security in the Internet of Things (IoT). The mainstream security approach proposed for the sensing layer of the IoT concentrates only on authentication while ignoring the more general models. Unreliable communications and resource constraints make the traditional access control techniques barely meet the requirements of the sensing layer of the IoT. In this paper, we propose a model that combines space and time with reputation to control access to the information within the sensing layer of the IoT. This model is called spatiotemporal access control based on reputation (STRAC). STRAC uses a lattice-based approach to decrease the size of policy bases. To solve the problem caused by unreliable communications, we propose both nondeterministic authorizations and stochastic authorizations. To more precisely manage the reputation of nodes, we propose two new mechanisms to update the reputation of nodes. These new approaches are the authority-based update mechanism (AUM) and the election-based update mechanism (EUM). We show how the model checker UPPAAL can be used to analyze the spatiotemporal access control model of an application. Finally, we also implement a prototype system to demonstrate the efficiency of our model.

Langerhans cell histiocytosis is a systemic disease resulting from the oligoclonal proliferation of Langerhans cells, occurring most commonly in children and young adults. The focal form of the disease, also known as eosinophilic granuloma, most frequently involves the calvaria. We present two cases of calvarial eosinophilic granulomas that were surgically removed. These tumors are reputed to have an excellent prognosis, even if local recurrences and systemic dissemination can occur during the follow-up. The authors discuss the pathogenesis and the evolutive profile but also the therapeutic management of solitary eosinophilic granuloma of the calvaria.

Finally, methods of evaluating public relations effectiveness at both the program level and the institutional level are explored.

Five-Year Olds, but Not Chimpanzees, Attempt to Manage Their Reputations

PubMed Central

Engelmann, Jan M.; Herrmann, Esther; Tomasello, Michael

2012-01-01

Virtually all theories of the evolution of cooperation require that cooperators find ways to interact with one another selectively, to the exclusion of cheaters. This means that individuals must make reputational judgments about others as cooperators, based on either direct or indirect evidence. Humans, and possibly other species, add another component to the process: they know that they are being judged by others, and so they adjust their behavior in order to affect those judgments – so-called impression management. Here, we show for the first time that already preschool children engage in such behavior. In an experimental study, 5-year-old human children share more and steal less when they are being watched by a peer than when they are alone. In contrast, chimpanzees behave the same whether they are being watched by a groupmate or not. This species difference suggests that humans' concern for their own self-reputation, and their tendency to manage the impression they are making on others, may be unique to humans among primates.

Neighborhood Reputation and Resident Sentiment in the Wake of the Las Vegas Foreclosure Crisis

PubMed Central

Pais, Jeremy; Batson, Christie D.; Monnat, Shannon M.

2014-01-01

This study examines how two major components of a neighborhood’s reputation—perceived disorder and collective efficacy—shape individuals’ sentiments toward their neighborhoods during the foreclosure crisis triggered by the Great Recession. Of central interest are whether neighborhood reputations are durable in the face of a crisis (neighborhood resiliency hypothesis) or whether neighborhood reputations wane during times of duress (foreclosure crisis hypothesis). Geo-coded individual-level data from the Las Vegas Metropolitan Area Social Survey merged with data on census tract foreclosure rates are used to address this question. The results provide qualified support for both perspectives. In support of the neighborhood resiliency hypothesis, collective efficacy is positively associated with how residents feel about the quality of their neighborhoods, and this relationship is unaltered by foreclosure rates. In support of the foreclosure crisis hypothesis, foreclosure rates mediate the effects of neighborhood disorder on resident sentiment. The implications of these findings for community resiliency are discussed. PMID:25678735

The costs of rape.

The current study examined costs experienced by victims of completed rape (n=49) and attempted sexual assault (n=91) using quantitative analyses of 13 domains: health, self-esteem, self-perceived attractiveness, self-perceived mate value, family relationships,work life, social life, social reputation, sexual reputation, desire to have sex, frequency of sex, enjoyment of sex, and long-term, committed relationships. Women also provided descriptive accounts of their experiences, and we used these to illustrate the costs in the victims' own words.Compared to victims of an attempted sexual assault, victims of a completed rape reported significantly more negative outcomes in 11 of the 13 domains. The most negatively affected domains were self-esteem, sexual reputation, frequency of sex, desire to have sex, and self-perceived mate value. Although victims of rape experienced more negative effects than victims of attempted sexual assault,both groups of victims reported negative effects in every domain.Discussion focuses on the implications of the differing degrees and patterns of the costs of attempted and completed sexual victimization.

A Lady 'in Proper Proportions'? Feminism, Lytton Strachey, and Florence Nightingale's Reputation, 1918-39.

PubMed

Southern, James

2017-03-01

Lytton Strachey's Eminent Victorians has long been regarded as a watershed in attitudes to Victorian culture, widely seen as having instigated a revolutionary backlash against the values and heroes of the Victorian era in England. Its impact, however, on the reputations of his four subjects-Thomas Arnold, General Gordon, Cardinal Manning and Florence Nightingale-has been subjected to surprisingly little scholarly attention. Drawing on the work of gender historians, this article reassesses Strachey's effect on the reputation of Nightingale, using biographies and contemporary reviews of Eminent Victorians. It argues that, far from 'debunking' the famous nurse as is generally assumed, Strachey in many ways enhanced her reputation and rendered her a plausible icon for English feminists of the 1920s and 1930s. © The Author [2016].

Reputation drives cooperative behaviour and network formation in human groups.

PubMed

Cuesta, Jose A; Gracia-Lázaro, Carlos; Ferrer, Alfredo; Moreno, Yamir; Sánchez, Angel

2015-01-19

Cooperativeness is a defining feature of human nature. Theoreticians have suggested several mechanisms to explain this ubiquitous phenomenon, including reciprocity, reputation, and punishment, but the problem is still unsolved. Here we show, through experiments conducted with groups of people playing an iterated Prisoner's Dilemma on a dynamic network, that it is reputation what really fosters cooperation. While this mechanism has already been observed in unstructured populations, we find that it acts equally when interactions are given by a network that players can reconfigure dynamically. Furthermore, our observations reveal that memory also drives the network formation process, and cooperators assort more, with longer link lifetimes, the longer the past actions record. Our analysis demonstrates, for the first time, that reputation can be very well quantified as a weighted mean of the fractions of past cooperative acts and the last action performed. This finding has potential applications in collaborative systems and e-commerce.

Propagation of Economic Inequality Through Reciprocity and Reputation.

PubMed

Hackel, Leor M; Zaki, Jamil

2018-04-01

Reciprocity and reputation are powerful tools for encouraging cooperation on a broad scale. Here, we highlight a potential side effect of these social phenomena: exacerbating economic inequality. In two novel economic games, we manipulated the amount of money with which participants were endowed and then gave them the opportunity to share resources with others. We found that people reciprocated more toward higher-wealth givers, compared with lower-wealth givers, even when those givers were equally generous. Wealthier givers also achieved better reputations than less wealthy ones and therefore received more investments in a social marketplace. These discrepancies were well described by a formal model of reinforcement learning: Individuals who weighted monetary outcomes, rather than generosity, when learning about interlocutors also most strongly helped wealthier individuals. This work demonstrates that reciprocity and reputation-although globally increasing prosociality-can widen wealth gaps and provides a precise account of how inequality grows through social processes.

Evolutionary models of human cooperation are increasingly emphasizing the role of reputation and the requisite truthful "gossiping" about reputation-relevant behavior. If resources were allocated among individuals according to their reputations, competition for resources via competition for "good" reputations would have created incentives for exaggerated or deceptive gossip about oneself and one's competitors in ancestral societies. Correspondingly, humans should have psychological adaptations to assess gossip veracity. Using social psychological methods, we explored cues of gossip veracity in four experiments. We found that simple reiteration increased gossip veracity, but only for those who found the gossip relatively uninteresting. Multiple sources of gossip increased its veracity, as did the independence of those sources. Information that suggested alternative, benign interpretations of gossip decreased its veracity. Competition between a gossiper and her target decreased gossip veracity. These results provide preliminary evidence for psychological adaptations for assessing gossip veracity, mechanisms that might be used to assess veracity in other domains involving social exchange of information.

The association between having a reputation for valuing popularity and relational aggression was assessed in a sample of 126 female children and adolescents (mean age = 12.43 years) at a 54-day residential summer camp for girls. Having a reputation for valuing popularity was positively related to relational aggression. This association was moderated by both popularity and physiological reactivity to social exclusion (i.e., respiratory sinus arrhythmia reactivity [RSAR] and heart rate reactivity [HRR]). Popular girls with a reputation for valuing popularity were at greater risk for engaging in relational aggression when they also exhibited blunted reactivity to social exclusion. Conversely, girls who had a reputation for valuing popularity but were not popular (i.e., the "wannabes") were at risk for engaging in relational aggression when they exhibited heightened reactivity to exclusion.

Cooperativeness is a defining feature of human nature. Theoreticians have suggested several mechanisms to explain this ubiquitous phenomenon, including reciprocity, reputation, and punishment, but the problem is still unsolved. Here we show, through experiments conducted with groups of people playing an iterated Prisoner's Dilemma on a dynamic network, that it is reputation what really fosters cooperation. While this mechanism has already been observed in unstructured populations, we find that it acts equally when interactions are given by a network that players can reconfigure dynamically. Furthermore, our observations reveal that memory also drives the network formation process, and cooperators assort more, with longer link lifetimes, the longer the past actions record. Our analysis demonstrates, for the first time, that reputation can be very well quantified as a weighted mean of the fractions of past cooperative acts and the last action performed. This finding has potential applications in collaborative systems and e-commerce. PMID:25598347

Evolutionary stability and resistance to cheating in an indirect reciprocity model based on reputation.

PubMed

Martinez-Vaquero, Luis A; Cuesta, José A

2013-05-01

Indirect reciprocity is one of the main mechanisms to explain the emergence and sustainment of altruism in societies. The standard approach to indirect reciprocity is reputation models. These are games in which players base their decisions on their opponent's reputation gained in past interactions with other players (moral assessment). The combination of actions and moral assessment leads to a large diversity of strategies; thus determining the stability of any of them against invasions by all the others is a difficult task. We use a variant of a previously introduced reputation-based model that let us systematically analyze all these invasions and determine which ones are successful. Accordingly, we are able to identify the third-order strategies (those which, apart from the action, judge considering both the reputation of the donor and that of the recipient) that are evolutionarily stable. Our results reveal that if a strategy resists the invasion of any other one sharing its same moral assessment, it can resist the invasion of any other strategy. However, if actions are not always witnessed, cheaters (i.e., individuals with a probability of defecting regardless of the opponent's reputation) have a chance to defeat the stable strategies for some choices of the probabilities of cheating and of being witnessed. Remarkably, by analyzing this issue with adaptive dynamics we find that whether an honest population resists the invasion of cheaters is determined by a Hamilton-like rule, with the probability that the cheat is discovered playing the role of the relatedness parameter.

Spatiotemporal Access Model Based on Reputation for the Sensing Layer of the IoT

PubMed Central

Guo, Yunchuan; Yin, Lihua; Li, Chao

2014-01-01

Access control is a key technology in providing security in the Internet of Things (IoT). The mainstream security approach proposed for the sensing layer of the IoT concentrates only on authentication while ignoring the more general models. Unreliable communications and resource constraints make the traditional access control techniques barely meet the requirements of the sensing layer of the IoT. In this paper, we propose a model that combines space and time with reputation to control access to the information within the sensing layer of the IoT. This model is called spatiotemporal access control based on reputation (STRAC). STRAC uses a lattice-based approach to decrease the size of policy bases. To solve the problem caused by unreliable communications, we propose both nondeterministic authorizations and stochastic authorizations. To more precisely manage the reputation of nodes, we propose two new mechanisms to update the reputation of nodes. These new approaches are the authority-based update mechanism (AUM) and the election-based update mechanism (EUM). We show how the model checker UPPAAL can be used to analyze the spatiotemporal access control model of an application. Finally, we also implement a prototype system to demonstrate the efficiency of our model. PMID:25177731

Using meta-quality to assess the utility of volunteered geographic information for science.

Volunteered geographic information (VGI) has strong potential to be increasingly valuable to scientists in collaboration with non-scientists. The abundance of mobile phones and other wireless forms of communication open up significant opportunities for the public to get involved in scientific research. As these devices and activities become more abundant, questions of uncertainty and error in volunteer data are emerging as critical components for using volunteer-sourced spatial data. Here we present a methodology for using VGI and assessing its sensitivity to three types of error. More specifically, this study evaluates the reliability of data from volunteers based on their historical patterns. The specific context is a case study in surveillance of tsetse flies, a health concern for being the primary vector of African Trypanosomiasis. Reliability, as measured by a reputation score, determines the threshold for accepting the volunteered data for inclusion in a tsetse presence/absence model. Higher reputation scores are successful in identifying areas of higher modeled tsetse prevalence. A dynamic threshold is needed but the quality of VGI will improve as more data are collected and the errors in identifying reliable participants will decrease. This system allows for two-way communication between researchers and the public, and a way to evaluate the reliability of VGI. Boosting the public's ability to participate in such work can improve disease surveillance and promote citizen science. In the absence of active surveillance, VGI can provide valuable spatial information given that the data are reliable.

Correlation of data within electronic health records is necessary for implementation of various clinical decision support functions, including patient summarization. A key type of correlation is linking medications to clinical problems; while some databases of problem-medication links are available, they are not robust and depend on problems and medications being encoded in particular terminologies. Crowdsourcing represents one approach to generating robust knowledge bases across a variety of terminologies, but more sophisticated approaches are necessary to improve accuracy and reduce manual data review requirements. We sought to develop and evaluate a clinician reputation metric to facilitate the identification of appropriate problem-medication pairs through crowdsourcing without requiring extensive manual review. We retrieved medications from our clinical data warehouse that had been prescribed and manually linked to one or more problems by clinicians during e-prescribing between June 1, 2010 and May 31, 2011. We identified measures likely to be associated with the percentage of accurate problem-medication links made by clinicians. Using logistic regression, we created a metric for identifying clinicians who had made greater than or equal to 95% appropriate links. We evaluated the accuracy of the approach by comparing links made by those physicians identified as having appropriate links to a previously manually validated subset of problem-medication pairs. Of 867 clinicians who asserted a total of 237,748 problem-medication links during the study period, 125 had a reputation metric that predicted the percentage of appropriate links greater than or equal to 95%. These clinicians asserted a total of 2464 linked problem-medication pairs (983 distinct pairs). Compared to a previously validated set of problem-medication pairs, the reputation metric achieved a specificity of 99.5% and marginally improved the sensitivity of previously described knowledge bases. A reputation metric may be a valuable measure for identifying high quality clinician-entered, crowdsourced data. Copyright © 2013 Elsevier Inc. All rights reserved.

Dividuality, masculine respectability and reputation: how masculinity affects men's uptake of HIV treatment in rural eastern Uganda.

PubMed

Siu, Godfrey E; Seeley, Janet; Wight, Daniel

2013-07-01

There is increasing evidence in SSA that once infected with HIV men are disadvantaged compared to women in terms of uptake of treatment. In Uganda fewer men are on treatment, they tend to initiate treatment later, are difficult to retain on treatment and have a higher mortality while on treatment. This article discusses how men's response to HIV infection relates to their masculinity. We conducted participant observation and in-depth interviews with 26 men from a rural setting in eastern Uganda, in 2009-2010. They comprised men receiving HIV treatment, who had dropped treatment or did not seek it despite testing HIV positive, who had not tested but suspected infection, and those with other symptoms unrelated to HIV. Thematic analysis identified recurrent themes and variations across the data. Men drew from a range of norms to fulfil the social and individual expectations of being sufficiently masculine. The study argues that there are essentially two forms of masculinity in Mam-Kiror, one based on reputation and the other on respectability, with some ideals shared by both. Respectability was endorsed by 'the wider society', while reputation was endorsed almost entirely by men. Men's treatment seeking behaviours corresponded with different masculine ideologies. Family and societal expectations to be a family provider and respectable role model encouraged treatment, to regain and maintain health. However, reputational concern with strength and the capacity for hard physical work, income generation and sexual achievement discouraged uptake of HIV testing and treatment since it meant acknowledging weakness and an 'HIV patient' identity. Men's 'dividuality' allowed them to express different masculinities in different social contexts. We conclude that characteristics associated with respectable masculinity tend to encourage men's uptake of HIV treatment while those associated with reputational masculinity tend to undermine it.

To explore the nature and content of information publicly posted to Facebook by early-career veterinarians. Cross-sectional descriptive study. Sample-352 early-career veterinarians. Publicly accessible Facebook profiles were searched online from March to May 2010 for profiles of early-career veterinarians (graduates from 2004 through 2009) registered with the College of Veterinarians of Ontario, Canada. The content of veterinarians' Facebook profiles was evaluated and then categorized as low, medium, or high exposure in terms of the information a veterinarian had publicly posted to Facebook. Through the use of content analysis, high-exposure profiles were further analyzed for publicly posted information that may have posed risks to an individual's or the profession's public image. Facebook profiles for 352 of 494 (71%) registered early-career veterinarians were located. One-quarter (25%) of profiles were categorized as low exposure (ie, high privacy), over half (54%) as medium exposure (i.e., medium privacy), and 21% as high exposure (i.e., low privacy). Content analysis of the high-exposure profiles identified publicly posted information that may pose risks to an individual's or the profession's reputation, including breaches of client confidentiality, evidence of substance abuse, and demeaning comments toward others. Almost a quarter of veterinarians' Facebook profiles viewed in the present study contained publicly available content of a questionable nature that could pose a risk to the reputation of the individual, his or her practice, or the veterinary profession. The increased use of Facebook and all types of social media points to the need for raised awareness by veterinarians of all ages of how to manage one's personal and professional identities online to minimize reputation risks for individuals and their practices and to protect the reputation and integrity of the veterinary profession.

Identifying online user reputation based on the rating information of the user-object bipartite networks is important for understanding online user collective behaviors. Based on the Bayesian analysis, we present a parameter-free algorithm for ranking online user reputation, where the user reputation is calculated based on the probability that their ratings are consistent with the main part of all user opinions. The experimental results show that the AUC values of the presented algorithm could reach 0.8929 and 0.8483 for the MovieLens and Netflix data sets, respectively, which is better than the results generated by the CR and IARR methods. Furthermore, the experimental results for different user groups indicate that the presented algorithm outperforms the iterative ranking methods in both ranking accuracy and computation complexity. Moreover, the results for the synthetic networks show that the computation complexity of the presented algorithm is a linear function of the network size, which suggests that the presented algorithm is very effective and efficient for the large scale dynamic online systems.

Identifying the user reputation accurately is significant for the online social systems. For different fair rating parameter q, by changing the parameter values α and β of the beta probability distribution (RBPD) for ranking online user reputation, we investigate the effect of the initial configuration of the RBPD method for the online user ranking performance. Experimental results for the Netflix and MovieLens data sets show that when the parameter q equals to 0.8 and 0.9, the accuracy value AUC would increase about 4.5% and 3.5% for the Netflix data set, while the AUC value increases about 1.5% for the MovieLens data set when the parameter q is 0.9. Furthermore, we investigate the evolution characteristics of the AUC value for different α and β, and find that as the rating records increase, the AUC value increases about 0.2 and 0.16 for the Netflix and MovieLens data sets, indicating that online users' reputations will increase as they rate more and more objects.

Ad hoc networks are very helpful in situations when no fixed network infrastructure is available, such as natural disasters and military conflicts. In such a network, all wireless nodes are equal peers simultaneously serving as both senders and routers for other nodes. Therefore, how to route packets through reliable paths becomes a fundamental problems when behaviors of certain nodes deviate from wireless ad hoc routing protocols. We proposed a novel Dirichlet reputation model based on Bayesian inference theory which evaluates reliability of each node in terms of packet delivery. Our system offers a way to predict and select a reliablemore » path through combination of first-hand observation and second-hand reputation reports. We also proposed moving window mechanism which helps to adjust ours responsiveness of our system to changes of node behaviors. We integrated the Dirichlet reputation into routing protocol of wireless ad hoc networks. Our extensive simulation indicates that our proposed reputation system can improve good throughput of the network and reduce negative impacts caused by misbehaving nodes.« less

Are country reputations for good and bad leadership on AIDS deserved? An exploratory quantitative analysis.

PubMed

Nattrass, Nicoli

2008-12-01

Some countries (e.g. Brazil) have good reputations on AIDS policy, whereas others, (notably South Africa) have been criticized for inadequate leadership. Cross-country regression analysis reveals that these 'poster children' for AIDS leadership have indeed performed better or worse than expected given their economic and institutional constraints and the demographic and health challenges facing them. Regressions were run on HAART coverage (number on highly active antiretroviral therapy as percentage of total need) and MTCTP coverage (pregnant HIV+ women accessing mother-to-child-transmission prevention services as percentage of total need). Brazil, Cambodia, Thailand and Uganda (all of whom have established reputations for good leadership on AIDS performed consistently better than expected-as did Burkina-Faso, Suriname, Paraguay Costa Rica, Mali and Namibia. South Africa, which has the worst reputation for AIDS leadership, performed significantly below expectations-as did Uruguay and Trinidad and Tobago. The paper thus confirms much of the conventional wisdom on AIDS leadership at country level and suggests new areas for research.

Scientists' perception of ethical issues in nanomedicine: a case study.

2011-06-01

Research and development in nanomedicine has been accompanied by the consideration of ethical issues; however, little is known about how researchers working in this area perceive such issues. This case-study explores scientists' attitude towards and knowledge of ethical issues. Data were collected by semi-structured interviews with 22 nanomedicine practitioners and subject to content analysis. We found that scientists reflect with ambiguity on the reputed novelty of nanomedicine and what the ethical issues and risks are in their work. Respondents see no necessity for a paradigm shift in ethical considerations, but view ethical issues in nanomedicine as overlapping with those of other areas of biomedical research. Most respondents discuss ethical issues they faced in scientific work with their colleagues, but expect benefit from additional information and training on ethics. Our findings that scientists are motivated to reflect on ethical issues in their work, can contribute to the design of new strategies, including training programs, to engage scientists in ethical discussion and stimulate their responsibility as nanomedicine practitioners.

Oil and gas well drilling activities are associated with numerous hazards which have the potential to cause injury or harm for people, property and the environment. These hazards are also a threat for the reputation of drilling companies. To prevent accidents and undesired events in drilling operations it is essential to identify, evaluate, assess and control the attendant risks. In this work, a structured methodology is proposed for risk assessment of drilling activities. A case study is performed to identify, analyze and assess the risks arising from human factors in one of the on shore drilling sites in southern Iran. A total of 17 major hazards were identified and analyzed using the proposed methodology. The results showed that the residual risks of 100% of these hazards were in the acceptable or transitional zone, and their levels were expected to be lowered further by proper controls. This structured methodology may also be used in other drilling sites and companies for assessing the risks.

A Conceptual Framework for Decision-making Support in Uncertainty- and Risk-based Diagnosis of Rare Clinical Cases by Specialist Physicians.

PubMed

Santos, Adriano A; Moura, J Antão B; de Araújo, Joseana Macêdo Fechine Régis

2015-01-01

Mitigating uncertainty and risks faced by specialist physicians in analysis of rare clinical cases is something desired by anyone who needs health services. The number of clinical cases never seen by these experts, with little documentation, may introduce errors in decision-making. Such errors negatively affect well-being of patients, increase procedure costs, rework, health insurance premiums, and impair the reputation of specialists and medical systems involved. In this context, IT and Clinical Decision Support Systems (CDSS) play a fundamental role, supporting decision-making process, making it more efficient and effective, reducing a number of avoidable medical errors and enhancing quality of treatment given to patients. An investigation has been initiated to look into characteristics and solution requirements of this problem, model it, propose a general solution in terms of a conceptual risk-based, automated framework to support rare-case medical diagnostics and validate it by means of case studies. A preliminary validation study of the proposed framework has been carried out by interviews conducted with experts who are practicing professionals, academics, and researchers in health care. This paper summarizes the investigation and its positive results. These results motivate continuation of research towards development of the conceptual framework and of a software tool that implements the proposed model.

Effect of peer nominations of teacher-student support at individual and classroom levels on social and academic outcomes.

PubMed

Hughes, Jan N; Im, Myung Hee; Wehrly, Sarah E

2014-06-01

This longitudinal study examined the prospective relations between 713 elementary students' individual peer teacher support reputation (PTSR) and a measure of the classroom-wide dispersion of peer nominations of teacher support (Centralization of Teacher Support) on students' peer relatedness (i.e., peer acceptance and peer academic reputation) and academic motivation (i.e., academic self-efficacy and teacher-rated behavioral engagement). PTSR was measured as the proportion of classmates who nominated a given student on a descriptor of teacher-student support. Centralization of Teacher Support was assessed using social network analysis to identify the degree to which peer nominations of teacher support in a classroom centered on a few students. PTSR predicted changes in all student outcomes, above academic achievement and relevant covariates. Centralization of Teacher Support predicted changes in students' peer academic reputation, net the effect of PTSR and covariates. Students' academic achievement moderated effects of PTSR and Centralization of Teacher Support on some outcomes. Findings highlight the importance of peers' perceptions of teacher support and of the structure of those perceptions for children's social and academic outcomes. Implications for practice are discussed. Copyright © 2014 Society for the Study of School Psychology. Published by Elsevier Ltd. All rights reserved.

Powering up with indirect reciprocity in a large-scale field experiment.

PubMed

Yoeli, Erez; Hoffman, Moshe; Rand, David G; Nowak, Martin A

2013-06-18

A defining aspect of human cooperation is the use of sophisticated indirect reciprocity. We observe others, talk about others, and act accordingly. We help those who help others, and we cooperate expecting that others will cooperate in return. Indirect reciprocity is based on reputation, which spreads by communication. A crucial aspect of indirect reciprocity is observability: reputation effects can support cooperation as long as peoples' actions can be observed by others. In evolutionary models of indirect reciprocity, natural selection favors cooperation when observability is sufficiently high. Complimenting this theoretical work are experiments where observability promotes cooperation among small groups playing games in the laboratory. Until now, however, there has been little evidence of observability's power to promote large-scale cooperation in real world settings. Here we provide such evidence using a field study involving 2413 subjects. We collaborated with a utility company to study participation in a program designed to prevent blackouts. We show that observability triples participation in this public goods game. The effect is over four times larger than offering a $25 monetary incentive, the company's previous policy. Furthermore, as predicted by indirect reciprocity, we provide evidence that reputational concerns are driving our observability effect. In sum, we show how indirect reciprocity can be harnessed to increase cooperation in a relevant, real-world public goods game.

Based on the practices at Xuzhou Central Hospital, the authors analyzed the improvements in the healthcare quality and economic efficiency after implementing a brand marketing strategy. Using methods including questionnaires and business controlling means, we summarized that the improvements to the healthcare quality and economic efficiency after strategies were implemented in the areas of network, reputation, academic research, and public welfare. After the implementation of a brand marketing campaign, the medical service quality and brand reputation have been greatly improved. Meanwhile, a central hospital group was formed and gradually became the central healthcare provider in the Huaihai Economic Zone. The new marketing facilitated the drastic increase of medical service and brand reputation.

Social networks, market transactions, and reputation as a central resource. The Mercado del Mar, a fish market in central Mexico

PubMed Central

Hernández, Juan M.

2017-01-01

Fish consumption in Mexico is considered low (around 12 kg per person per year) and non-homogeneously distributed across the country. One of the reasons for this situation is the scarcity of wholesale selling sites. In this context, the Mercado del Mar (MM), located in Guadalajara city, Jalisco, is the second biggest wholesale fish market in Mexico, with a distribution of about 500 tons per day and a variety of about 350 different species of fish. In this paper, we argue that MM has accumulated social capital, which is formed from two main resources: buyer and seller relationships, and reputation. Specifically, the MM manages a broad and intensive interaction among business actors and the already achieved reputation allows the MM to adapt to market changes. To validate our hypotheses, an empirical study was conducted in 2015 by means of interviews to fish wholesalers in the MM and a sample of their suppliers and buyers. For simplicity we have only considered fresh water fish. We have followed snow-ball sampling as the survey strategy. Results show that the MM has responded to fish market dynamics organizing a complex network of buyers and suppliers whose relationships can be explained in the form of strong and weak ties. At the same time, reputation has been the central resource to build this social capital and also gives place to market transactions. Additionally, the strategic position of Guadalajara city and the well-connected routes have facilitated fish bulking and distribution in the region. PMID:29016637

To examine the psychometric properties of the Patient-Reported Outcomes Measurement Information System (PROMIS®) peer relationships short form (PR-SF), including association with peer-reported friendships, likeability, and social reputation. 203 children (Mage = 10.12 years, SD = 2.37, range = 6-14) in Grades 1-8 completed the 8-item PR-SF and friendship nominations, like ratings, and social reputation measures about their peers during 2 classroom visits approximately 4 months apart, as part of a larger study. A confirmatory factor analysis, followed by an exploratory factor analysis, was conducted to examine the factor structure of the PR-SF. Spearman correlations between the PR-SF and peer-reported outcomes evaluated construct validity. For the PR-SF, a 2-factor solution demonstrated better fit than a 1-factor solution. The 2 factors appear to assess friendship quality (3 items) and peer acceptance (5 items). Reliability was marginal for the friendship quality factor (.66) but adequate for the acceptance factor (.85); stability was .34 for the PR-SF over 4 months. The PR-SF (8 items) and acceptance factor (5 items) both had modest but significant correlations with measures of friendship (rs = .25-.27), likeability (rs = .21-.22), and social reputation (rs = .29-.44). The PR-SF appears to be measuring two distinct aspects of social functioning. The 5-item peer acceptance scale is modestly associated with peer-reported friendship, likeability, and social reputation. Although not a replacement for peer-reported outcomes, the PR-SF is a promising patient-reported outcome for peer relationships in youth.

Reputation and Competition in a Hidden Action Model

PubMed Central

Fedele, Alessandro; Tedeschi, Piero

2014-01-01

The economics models of reputation and quality in markets can be classified in three categories. (i) Pure hidden action, where only one type of seller is present who can provide goods of different quality. (ii) Pure hidden information, where sellers of different types have no control over product quality. (iii) Mixed frameworks, which include both hidden action and hidden information. In this paper we develop a pure hidden action model of reputation and Bertrand competition, where consumers and firms interact repeatedly in a market with free entry. The price of the good produced by the firms is contractible, whilst the quality is noncontractible, hence it is promised by the firms when a contract is signed. Consumers infer future quality from all available information, i.e., both from what they know about past quality and from current prices. According to early contributions, competition should make reputation unable to induce the production of high-quality goods. We provide a simple solution to this problem by showing that high quality levels are sustained as an outcome of a stationary symmetric equilibrium. PMID:25329387

How feedback biases give ineffective medical treatments a good reputation.

PubMed

de Barra, Mícheál; Eriksson, Kimmo; Strimling, Pontus

2014-08-21

Medical treatments with no direct effect (like homeopathy) or that cause harm (like bloodletting) are common across cultures and throughout history. How do such treatments spread and persist? Most medical treatments result in a range of outcomes: some people improve while others deteriorate. If the people who improve are more inclined to tell others about their experiences than the people who deteriorate, ineffective or even harmful treatments can maintain a good reputation. The intent of this study was to test the hypothesis that positive outcomes are overrepresented in online medical product reviews, to examine if this reputational distortion is large enough to bias people's decisions, and to explore the implications of this bias for the cultural evolution of medical treatments. We compared outcomes of weight loss treatments and fertility treatments in clinical trials to outcomes reported in 1901 reviews on Amazon. Then, in a series of experiments, we evaluated people's choice of weight loss diet after reading different reviews. Finally, a mathematical model was used to examine if this bias could result in less effective treatments having a better reputation than more effective treatments. Data are consistent with the hypothesis that people with better outcomes are more inclined to write reviews. After 6 months on the diet, 93% (64/69) of online reviewers reported a weight loss of 10 kg or more while just 27% (19/71) of clinical trial participants experienced this level of weight change. A similar positive distortion was found in fertility treatment reviews. In a series of experiments, we show that people are more inclined to begin a diet with many positive reviews, than a diet with reviews that are representative of the diet's true effect. A mathematical model of medical cultural evolution shows that the size of the positive distortion critically depends on the shape of the outcome distribution. Online reviews overestimate the benefits of medical treatments, probably because people with negative outcomes are less inclined to tell others about their experiences. This bias can enable ineffective medical treatments to maintain a good reputation.

Effect of Peer Nominations of Teacher-Student Support at Individual and Classroom Levels on Social and Academic Outcomes

Hughes, Jan N.; Im, Myung Hee; Wehrly, Sarah E.

2014-01-01

This longitudinal study examined the prospective relations between 713 elementary students’ individual peer teacher support reputation (PTSR) and a measure of the classroom-wide dispersion of peer nominations of teacher support (Centralization of Teacher Support) on students’ peer relatedness (i.e., peer acceptance and peer academic reputation) and academic motivation (i.e., academic self-efficacy and teacher-rated behavioral engagement). PTSR was measured as the proportion of classmates who nominated a given student on a descriptor of teacher-student support. Centralization of Teacher Support was assessed using social network analysis to identify the degree to which peer nominations of teacher support in a classroom centered on a few students. PTSR predicted changes in all student outcomes, above academic achievement and relevant covariates. Centralization of Teacher Support predicted changes in students’ peer academic reputation, net the effect of PTSR and covariates. Students’ academic achievement moderated effects of PTSR and Centralization of Teacher Support on some outcomes. Findings highlight the importance of peers’ perceptions of teacher support and of the structure of those perceptions for children’s social and academic outcomes. Implications for practice are discussed. PMID:24930822

Luke May of Seattle--"America's Sherlock Holmes".

PubMed

Beck, J

1992-01-01

This paper provides a brief biography of Luke S. May (1886-1965), whose pioneering work in forensic science in the United States has not received full recognition. May began as a private detective in Salt Lake City, Utah, shortly after the turn of the century and later established his own agency, the Revelare International Secret Service, which he moved to Seattle, Washington, in 1919. Although basically self-taught in scientific matters, May built a solid reputation among police agencies and attorneys in the Pacific Northwest and Western Canada as a serious and effective scientific investigator in the era before public crime laboratories. This reputation as "America's Sherlock Holmes" also led to his being consulted on the establishment of the first American crime laboratory at Northwestern University in Chicago, Illinois, and on a laboratory for the Royal Canadian Mounted Police at Regina, in Saskatchewan, Canada. He contributed to a landmark case of court acceptance of toolmark identification, invented specialized instruments, and founded an institute to teach scientific criminal investigation to police officers. His earliest associates were John L. Harris and J. Clark Sellers, both of whom became recognized document examiners on the West Coast and were followed by a second and a third generation of practitioners.

Current transition from traditional economic model of selling and buying to sharing economic business creates a huge impact on consumers’ preferences to participate in collaborative consumption. The market entrance of sharing economic business is relatively new, thus it builds scepticism among consumers. Consumers’ trust becomes the most crucial aspect in determining their willingness to participate in collaborative consumption. This study will reveal the effects of perceived risks (performance and social), reputation and Electronic Word-of Mouth (E-WOM) on Malaysian consumers’ intention of collaborative consumption, especially for Uber car sharing service. This study inspires to enrich the literature for collaborative consumption and perceived risk theory. From the practical perspective, this study may provide insights in assisting the collaborative consumption service providers especially Uber car users on factors influencing the intention to engage in such service.

Do narcissists have insight into the negative aspects of their personality and reputation? Using both clinical and subclinical measures of narcissism, we examined others’ perceptions, self-perceptions and meta-perceptions of narcissists across a wide range of traits for a new acquaintance and close other (Study 1), longitudinally with a group of new acquaintances (Study 2), and among coworkers (Study 3). Results bring us to three surprising conclusions about narcissists: 1) they understand that others see them less positively than they see themselves (i.e., their meta-perceptions are less biased than are their self-perceptions), 2) they have some insight into the fact that they make positive first impressions that deteriorate over time, and 3) they have insight into their narcissistic personality (e.g., they describe themselves as arrogant). These findings shed light on some of the psychological mechanisms underlying narcissism. PMID:21604895

Investigating motivating factors for sound hospital waste management.

PubMed

Ali, Mustafa; Wang, Wenping; Chaudhry, Nawaz

2016-08-01

Sustainable management of hospital waste requires an active involvement of all key players. This study aims to test the hypothesis that three motivating factors, namely, Reputation, Liability, and Expense, influence hospital waste management. The survey for this study was conducted in two phases, with the pilot study used for exploratory factor analysis and the subsequent main survey used for cross-validation using confirmatory factor analysis. The hypotheses were validated through one-sample t tests. Correlations were established between the three motivating factors and organizational characteristics of hospital type, location, category, and size. The hypotheses were validated, and it was found that the factors of Liability and Expense varied considerably with respect to location and size of a hospital. The factor of Reputation, however, did not exhibit significant variation. In conclusion, concerns about the reputation of a facility and an apprehension of liability act as incentives for sound hospital waste management, whereas concerns about financial costs and perceived overburden on staff act as disincentives. This paper identifies the non economic motivating factors that can be used to encourage behavioral changes regarding waste management at hospitals in resource constrained environments. This study discovered that organizational characteristics such as hospital size and location cause the responses to vary among the subjects. Hence a policy maker must take into account the institutional setting before introducing a change geared towards better waste management outcomes across hospitals. This study covers a topic that has hitherto been neglected in resource constrained countries. Thus it can be used as one of the first steps to highlight and tackle the issue.

Does bibliometric research confer legitimacy to research assessment practice? A sociological study of reputational control, 1972-2016

PubMed Central

Jappe, Arlette; Pithan, David

2018-01-01

The use of bibliometric measures in the evaluation of research has increased considerably based on expertise from the growing research field of evaluative citation analysis (ECA). However, mounting criticism of such metrics suggests that the professionalization of bibliometric expertise remains contested. This paper investigates why impact metrics, such as the journal impact factor and the h-index, proliferate even though their legitimacy as a means of professional research assessment is questioned. Our analysis is informed by two relevant sociological theories: Andrew Abbott’s theory of professions and Richard Whitley’s theory of scientific work. These complementary concepts are connected in order to demonstrate that ECA has failed so far to provide scientific authority for professional research assessment. This argument is based on an empirical investigation of the extent of reputational control in the relevant research area. Using three measures of reputational control that are computed from longitudinal inter-organizational networks in ECA (1972–2016), we show that peripheral and isolated actors contribute the same number of novel bibliometric indicators as central actors. In addition, the share of newcomers to the academic sector has remained high. These findings demonstrate that recent methodological debates in ECA have not been accompanied by the formation of an intellectual field in the sociological sense of a reputational organization. Therefore, we conclude that a growing gap exists between an academic sector with little capacity for collective action and increasing demand for routine performance assessment by research organizations and funding agencies. This gap has been filled by database providers. By selecting and distributing research metrics, these commercial providers have gained a powerful role in defining de-facto standards of research excellence without being challenged by expert authority.

A Multi-Attribute Pheromone Ant Secure Routing Algorithm Based on Reputation Value for Sensor Networks

PubMed Central

Zhang, Lin; Yin, Na; Fu, Xiong; Lin, Qiaomin; Wang, Ruchuan

2017-01-01

With the development of wireless sensor networks, certain network problems have become more prominent, such as limited node resources, low data transmission security, and short network life cycles. To solve these problems effectively, it is important to design an efficient and trusted secure routing algorithm for wireless sensor networks. Traditional ant-colony optimization algorithms exhibit only local convergence, without considering the residual energy of the nodes and many other problems. This paper introduces a multi-attribute pheromone ant secure routing algorithm based on reputation value (MPASR). This algorithm can reduce the energy consumption of a network and improve the reliability of the nodes’ reputations by filtering nodes with higher coincidence rates and improving the method used to update the nodes’ communication behaviors. At the same time, the node reputation value, the residual node energy and the transmission delay are combined to formulate a synthetic pheromone that is used in the formula for calculating the random proportion rule in traditional ant-colony optimization to select the optimal data transmission path. Simulation results show that the improved algorithm can increase both the security of data transmission and the quality of routing service. PMID:28282894

Knowledge of Social Affiliations Biases Economic Decisions

Martinez, Joel E.; Mack, Michael L.; Gelman, Bernard D.; Preston, Alison R.

2016-01-01

An individual’s reputation and group membership can produce automatic judgments and behaviors toward that individual. Whether an individual’s social reputation impacts interactions with affiliates has yet to be demonstrated. We tested the hypothesis that during initial encounters with others, existing knowledge of their social network guides behavior toward them. Participants learned reputations (cooperate, defect, or equal mix) for virtual players through an iterated economic game (EG). Then, participants learned one novel friend for each player. The critical question was how participants treated the friends in a single-shot EG after the friend-learning phase. Participants tended to cooperate with friends of cooperators and defect on friends of defectors, indicative of a decision making bias based on memory for social affiliations. Interestingly, participants’ explicit predictions of the friends’ future behavior showed no such bias. Moreover, the bias to defect on friends of defectors was enhanced when affiliations were learned in a social context; participants who learned to associate novel faces with player faces during reinforcement learning did not show reputation-based bias for associates of defectors during single-shot EG. These data indicate that when faced with risky social decisions, memories of social connections influence behavior implicitly. PMID:27441563

Testosterone has been associated with economically egoistic and materialistic behaviors, but -defensibly driven by reputable status seeking- also with economically fair, generous and cooperative behaviors. Problematically, social status and economic resources are inextricably intertwined in humans, thus testosterone's primal motives are concealed. We critically addressed this issue by performing a placebo-controlled single-dose testosterone administration in young women, who played a game of bluff poker wherein concerns for status and resources collide. The profit-maximizing strategy in this game is to mislead the other players by bluffing randomly (independent of strength of the hand), thus also when holding very poor cards (cold bluffing). The profit-maximizing strategy also dictates the players in this poker game to never call the other players' bluffs. For reputable-status seeking these materialistic strategies are disadvantageous; firstly, being caught cold bluffing damages one's reputation by revealing deceptive intent, and secondly, not calling the other players' bluffs signals submission in blindly tolerating deception. Here we show that testosterone administration in this game of bluff poker significantly reduces random bluffing, as well as cold bluffing, while significantly increasing calling. Our data suggest that testosterone in humans primarily motivates for reputable-status seeking, even when this elicits behaviors that are economically disadvantageous.

Powering up with indirect reciprocity in a large-scale field experiment

A defining aspect of human cooperation is the use of sophisticated indirect reciprocity. We observe others, talk about others, and act accordingly. We help those who help others, and we cooperate expecting that others will cooperate in return. Indirect reciprocity is based on reputation, which spreads by communication. A crucial aspect of indirect reciprocity is observability: reputation effects can support cooperation as long as peoples’ actions can be observed by others. In evolutionary models of indirect reciprocity, natural selection favors cooperation when observability is sufficiently high. Complimenting this theoretical work are experiments where observability promotes cooperation among small groups playing games in the laboratory. Until now, however, there has been little evidence of observability’s power to promote large-scale cooperation in real world settings. Here we provide such evidence using a field study involving 2413 subjects. We collaborated with a utility company to study participation in a program designed to prevent blackouts. We show that observability triples participation in this public goods game. The effect is over four times larger than offering a $25 monetary incentive, the company’s previous policy. Furthermore, as predicted by indirect reciprocity, we provide evidence that reputational concerns are driving our observability effect. In sum, we show how indirect reciprocity can be harnessed to increase cooperation in a relevant, real-world public goods game. PMID:23754399

Online citizen science offers a low-cost way to strengthen the infrastructure for scientific research and engage members of the public in science. As the sustainability of online citizen science projects depends on volunteers who contribute their skills, time, and energy, the objective of this study is to investigate effects of motivational factors on the quantity and quality of citizen scientists' contribution. Building on the social movement participation model, findings from a longitudinal empirical study in three different citizen science projects reveal that quantity of contribution is determined by collective motives, norm-oriented motives, reputation, and intrinsic motives. Contribution quality, on the other hand, is positively affected only by collective motives and reputation. We discuss implications for research on the motivation for participation in technology-mediated social participation and for the practice of citizen science. PMID:24690612

Gossip and ostracism promote cooperation in groups.

PubMed

Feinberg, Matthew; Willer, Robb; Schultz, Michael

2014-03-01

The widespread existence of cooperation is difficult to explain because individuals face strong incentives to exploit the cooperative tendencies of others. In the research reported here, we examined how the spread of reputational information through gossip promotes cooperation in mixed-motive settings. Results showed that individuals readily communicated reputational information about others, and recipients used this information to selectively interact with cooperative individuals and ostracize those who had behaved selfishly, which enabled group members to contribute to the public good with reduced threat of exploitation. Additionally, ostracized individuals responded to exclusion by subsequently cooperating at levels comparable to those who were not ostracized. These results suggest that the spread of reputational information through gossip can mitigate egoistic behavior by facilitating partner selection, thereby helping to solve the problem of cooperation even in noniterated interactions.

Optimal Contractor Selection in Construction Industry: The Fuzzy Way

Krishna Rao, M. V.; Kumar, V. S. S.; Rathish Kumar, P.

2018-02-01

A purely price-based approach to contractor selection has been identified as the root cause for many serious project delivery problems. Therefore, the capability of the contractor to execute the project should be evaluated using a multiple set of selection criteria including reputation, past performance, performance potential, financial soundness and other project specific criteria. An industry-wide questionnaire survey was conducted with the objective of identifying the important criteria for adoption in the selection process. In this work, a fuzzy set based model was developed for contractor prequalification/evaluation, by using effective criteria obtained from the percept of construction professionals, taking subjective judgments of decision makers also into consideration. A case study consisting of four alternatives (contractors in the present case) solicited from a public works department of Pondicherry in India, is used to illustrate the effectiveness of the proposed approach. The final selection of contractor is made based on the integrated score or Overall Evaluation Score of the decision alternative in prequalification as well as bid evaluation stages.

Human dignity and professional reputation under threat: Iranian Nurses' experiences of workplace violence.

Workplace violence against nurses is a challenging problem in both developed and developing countries. Because the concept of violence bears some cultural load, nurses' understanding is region-specific. This study explores Iranian nurses' perceptions of workplace violence. Using qualitative content analysis, 22 registered nurses underwent unstructured, in-depth interviews. The main themes of threats to human dignity and professional reputation emerged, plus four categories: physical violence, psychological violence, honor insults, and ethnic-religious insults. The term "honor insults," as a unique finding, was used instead of "sexual harassment." These findings may help to redefine workplace violence based on cultural background, design strategies for supporting nurses, and prevent and manage such violence. © 2016 John Wiley & Sons Australia, Ltd.

Building collaborative working relationships (CWRs) with physicians or other prescribers is an important step for community pharmacists in establishing a collaborative practice agreement (CPA). This case study describes the individual, context, and exchange factors that drive pharmacist-physician CWR development for community pharmacy-based point-of-care (POC) testing. Two physicians who had entered in a CPA with community pharmacists to provide POC testing were surveyed and interviewed. High scores on the pharmacist-physician collaborative index indicated a high level of collaboration between the physicians and the pharmacist who initiated the relationship. Trust was established through the physicians' personal relationships with the pharmacist or due to the community pharmacy organization's strong reputation. The physicians' individual perceptions of community pharmacy-based POC testing affected their CWRs and willingness to establish a CPA. These findings suggest that exchange characteristics remain significant factors in CWR development. Individual factors may also contribute to physicians' willingness to advance their CWR to include a CPA for POC testing. Copyright © 2017 Elsevier Inc. All rights reserved.

An example of the teacher expectation effect in mixed ability teaching

NASA Astrophysics Data System (ADS)

Matthews, G. P.

Much interest has been shown recently in teacher expectation or self-fulfilling prophecy effects, despite the difficulty of making objective observations of the phenomenon. The present case study concerns a population of twelve mixed-ability chemistry classes in a comprehensive school in the U.K. The poor behavior of one of the groups led to a stigma being attached to it by staff, and for various doubtful reasons, this became associated with another class as well. A statistical analysis of examination marks shows that neither reputation was justified in terms of academic achievement, and quantifies possible teacher expectation effects arising from the situation. The findings demonstrate the ease with which academic achievements can be hampered unwittingly by the prejudices of a teacher even in a well-structured learning situation.

How to design an accurate and robust ranking algorithm is a fundamental problem with wide applications in many real systems. It is especially significant in online rating systems due to the existence of some spammers. In the literature, many well-performed iterative ranking methods have been proposed. These methods can effectively recognize the unreliable users and reduce their weight in judging the quality of objects, and finally lead to a more accurate evaluation of the online products. In this paper, we design an iterative ranking method with high performance in both accuracy and robustness. More specifically, a reputation redistribution process is introduced to enhance the influence of highly reputed users and two penalty factors enable the algorithm resistance to malicious behaviors. Validation of our method is performed in both artificial and real user-object bipartite networks. PMID:24819119

State of the Art in Trust and Reputation Models in P2P networks

NASA Astrophysics Data System (ADS)

Mármol, Félix Gómez; Pérez, Gregorio Martínez

Ensuring security in a distributed environment such as P2P networks is a critical issue nowadays. Nevertheless, it is in those kind of scenarios in which entities can enter or leave the community whenever they want, where traditional mboxsecurity schemes can not always be applied. Specifically, the use of a PKI (Public Key Infrastructure) may be unacceptable within highly distributed systems. Therefore, modeling concepts like trust and reputation may result very helpful and useful when trying to gain a certain level of security and confidence among inter-operating entities. Thus, this chapter presents a review of some of the most representative trust and reputation models for P2P networks, discussing their main characteristics and also their weaknesses and deficiencies. Open issues and challenges associated with them will be also covered.

Adjusting one's behaviour in response to eavesdropping bystanders is considered a sophisticated social strategy, yet the underlying mechanisms are not well studied. Cleaner wrasse, Labroides dimidiatus, cooperate by eating ectoparasites off "client" fishes, or cheat (i.e. bite) and eat client mucus. Image scoring by bystander clients generally causes cleaners from socially-complex (i.e. high cleaner and client abundance; high client species richness) habitats to increase levels of cooperation. However, some individuals may periodically provide tactile stimulation to small resident clients, which attract bystanders close that are bitten, a form of tactical deception. Cortisol injection can reproduce this pattern. Here, we tested whether cleaners from socially-complex versus simple habitats respond differently to cortisol injections in terms of their cleaning interactions with clients. We found that only cleaners from the socially-complex habitat respond to cortisol injection with strategies functioning as tactical deception: i.e. increased tactile stimulation to small clients and increased cheating of large clients relative to small ones. At the socially-simple site, where reputation management is less important, cortisol-treated fish increased their overall levels of cheating, especially of small clients. Thus, strategic adjustments to cooperative behaviour and tactical deception are likely context-dependent, forming part of general reputation management abilities in cleaner wrasse.

While the existing trust models contain many drawbacks, we propose a new trust model based on the reputation of PKIs.

Resilient distributed control in the presence of misbehaving agents in networked control systems.

PubMed

Zeng, Wente; Chow, Mo-Yuen

2014-11-01

In this paper, we study the problem of reaching a consensus among all the agents in the networked control systems (NCS) in the presence of misbehaving agents. A reputation-based resilient distributed control algorithm is first proposed for the leader-follower consensus network. The proposed algorithm embeds a resilience mechanism that includes four phases (detection, mitigation, identification, and update), into the control process in a distributed manner. At each phase, every agent only uses local and one-hop neighbors' information to identify and isolate the misbehaving agents, and even compensate their effect on the system. We then extend the proposed algorithm to the leaderless consensus network by introducing and adding two recovery schemes (rollback and excitation recovery) into the current framework to guarantee the accurate convergence of the well-behaving agents in NCS. The effectiveness of the proposed method is demonstrated through case studies in multirobot formation control and wireless sensor networks.

IRLT: Integrating Reputation and Local Trust for Trustworthy Service Recommendation in Service-Oriented Social Networks

With the prevalence of Social Networks (SNs) and services, plenty of trust models for Trustworthy Service Recommendation (TSR) in Service-oriented SNs (S-SNs) have been proposed. The reputation-based schemes usually do not contain user preferences and are vulnerable to unfair rating attacks. Meanwhile, the local trust-based schemes generally have low reliability or even fail to work when the trust path is too long or does not exist. Thus it is beneficial to integrate them for TSR in S-SNs. This work improves the state-of-the-art Combining Global and Local Trust (CGLT) scheme and proposes a novel Integrating Reputation and Local Trust (IRLT) model which mainly includes four modules, namely Service Recommendation Interface (SRI) module, Local Trust-based Trust Evaluation (LTTE) module, Reputation-based Trust Evaluation (RTE) module and Aggregation Trust Evaluation (ATE) module. Besides, a synthetic S-SN based on the famous Advogato dataset is deployed and the well-known Discount Cumulative Gain (DCG) metric is employed to measure the service recommendation performance of our IRLT model with comparing to that of the excellent CGLT model. The results illustrate that our IRLT model is slightly superior to the CGLT model in honest environment and significantly outperforms the CGLT model in terms of the robustness against unfair rating attacks.

Trust-Building in Electronic Markets: Relative Importance and Interaction Effects of Trust-Building Mechanisms

NASA Astrophysics Data System (ADS)

Tams, Stefan

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

A Dominant Social Comparison Heuristic Unites Alternative Mechanisms for the Evolution of Indirect Reciprocity

2016-01-01

Cooperation is a fundamental human trait but our understanding of how it functions remains incomplete. Indirect reciprocity is a particular case in point, where one-shot donations are made to unrelated beneficiaries without any guarantee of payback. Existing insights are largely from two independent perspectives: i) individual-level cognitive behaviour in decision making, and ii) identification of conditions that favour evolution of cooperation. We identify a fundamental connection between these two areas by examining social comparison as a means through which indirect reciprocity can evolve. Social comparison is well established as an inherent human disposition through which humans navigate the social world by self-referential evaluation of others. Donating to those that are at least as reputable as oneself emerges as a dominant heuristic, which represents aspirational homophily. This heuristic is found to be implicitly present in the current knowledge of conditions that favour indirect reciprocity. The effective social norms for updating reputation are also observed to support this heuristic. We hypothesise that the cognitive challenge associated with social comparison has contributed to cerebral expansion and the disproportionate human brain size, consistent with the social complexity hypothesis. The findings have relevance for the evolution of autonomous systems that are characterised by one-shot interactions. PMID:27515119

What the United States can learn from Brazil in response to HIV/AIDS: international reputation and strategic centralization in a context of health policy devolution.

PubMed

Gómez, Eduardo J

2010-11-01

Contrary to what many may expect, this article argues that Brazil did a better job than the USA when it came to responding to HIV/AIDS. Because of the Brazilian government's concern about its international reputation and the partnerships it has forged with international donors and civil society, the government has been committed to strengthening decentralization processes by introducing both formal and informal re-centralization measures that strengthen health policy devolution, while effectively targeting the biggest at-risk groups. The US, in contrast, has not achieved these objectives, due to its lack of interest in increasing its international reputation and its focus on bi-lateral aid rather than investing in domestic policy. The paper closes by explaining the lessons that Brazil can teach the US and other large federations seeking to ensure that decentralization and prevention policy work more effectively.

Is There an Islamist Political Advantage?

PubMed Central

Cammett, Melani; Luong, Pauline Jones

2014-01-01

There is a widespread presumption that Islamists have an advantage over their opponents when it comes to generating mass appeal and winning elections. The question remains, however, as to whether these advantages—or, what we refer to collectively as an Islamist political advantage—actually exist. We argue that—to the extent that Islamists have a political advantage—the primary source of this advantage is reputation rather than the provision of social services, organizational capacity, or ideological hegemony. Our purpose is not to dismiss the main sources of the Islamist governance advantage identified in scholarly literature and media accounts, but to suggest a different causal path whereby each of these factors individually and sometimes jointly promotes a reputation for Islamists as competent, trustworthy, and pure. It is this reputation for good governance that enables Islamists to distinguish themselves in the streets and at the ballot box. PMID:25767370

The transparency paradox. Building trust, resolving disputes and optimising logistics on conventional and online drugs markets.

2016-09-01

In recent years, marketplaces in the darknet emerged where vendors and customers can exchange illicit drugs and other goods on digital platforms by using hidden internet services. The main thesis of this paper is that in an online environment, different practices for building trust and reputation emerge that stabilise market processes. Qualitative and quantitative data from a recent German project on conventional (offline) small-scale drug dealing as well as qualitative case studies on four online vendors operating on Agora market are used to explore alternative practices for building trust and reputation. They also explore the use of violence and logistics established on cryptomarkets in comparison to traditional dealing. To analyse the data we applied qualitative content analyses. For conventional commercial illicit drug dealing on various kinds of markets, trust between buyer and seller is a crucial issue, often emphasized by restricting deals to well-known persons. While this typically includes face-to-face contact, the opposite is true with online drug trading. It is characteristic of cryptomarkets that the parties involved in a transaction know neither the personal identity nor the physical location of one another. This is realised by using aliases, anonymising software, and cryptocurrencies for payments. Violence typically only plays a role in traditional drug dealing, but mostly, if at all, just as a latent threat for potential rule-breakers. Processing a transaction anonymously includes escrow services for the buyers, which makes trading more reliable, although they cannot completely prevent scamming. Furthermore, online drug marketplaces usually offer a customer feedback system that allows customers to rate vendors and review products. A positive vendor feedback helps building reputation and trust in such an online environment. With regard to logistics, most conventional small-scale dealers restrict their acts of selling to private surroundings to avoid encounters with law enforcement. In cryptomarkets, the purchased drugs are delivered by traditional postal services, sometimes to false addresses or to someone else's name to conceal the identity and address of the buyer. On virtual drug markets practices of building trust, conflict resolution and logistics is constantly evolving. They offer improved security solutions on the one hand while on the other hand scamming and fraud seem to be widely used on both online and conventional drug markets. Copyright © 2015 Elsevier B.V.

Security in wireless sensor networks is difficult to achieve because of the resource limitations of the sensor nodes. We propose a trust-based decision framework for wireless sensor networks coupled with a non-deterministic routing protocol.

This approach has been extensively simulated, obtaining good results, even for unrealistically complex attack scenarios. PMID:22412345

What Are Punishment and Reputation for?

PubMed Central

Krasnow, Max M.; Cosmides, Leda; Pedersen, Eric J.; Tooby, John

2012-01-01

Why did punishment and the use of reputation evolve in humans? According to one family of theories, they evolved to support the maintenance of cooperative group norms; according to another, they evolved to enhance personal gains from cooperation. Current behavioral data are consistent with both hypotheses (and both selection pressures could have shaped human cooperative psychology). However, these hypotheses lead to sharply divergent behavioral predictions in circumstances that have not yet been tested. Here we report results testing these rival predictions. In every test where social exchange theory and group norm maintenance theory made different predictions, subject behavior violated the predictions of group norm maintenance theory and matched those of social exchange theory. Subjects do not direct punishment toward those with reputations for norm violation per se; instead, they use reputation self-beneficially, as a cue to lower the risk that they personally will experience losses from defection. More tellingly, subjects direct their cooperative efforts preferentially towards defectors they have punished and away from those they haven’t punished; they avoid expending punitive effort on reforming defectors who only pose a risk to others. These results are not consistent with the hypothesis that the psychology of punishment evolved to uphold group norms. The circumstances in which punishment is deployed and withheld–its circuit logic–support the hypothesis that it is generated by psychological mechanisms that evolved to benefit the punisher, by allowing him to bargain for better treatment.

What are punishment and reputation for?

Why did punishment and the use of reputation evolve in humans? According to one family of theories, they evolved to support the maintenance of cooperative group norms; according to another, they evolved to enhance personal gains from cooperation. Current behavioral data are consistent with both hypotheses (and both selection pressures could have shaped human cooperative psychology). However, these hypotheses lead to sharply divergent behavioral predictions in circumstances that have not yet been tested. Here we report results testing these rival predictions. In every test where social exchange theory and group norm maintenance theory made different predictions, subject behavior violated the predictions of group norm maintenance theory and matched those of social exchange theory. Subjects do not direct punishment toward those with reputations for norm violation per se; instead, they use reputation self-beneficially, as a cue to lower the risk that they personally will experience losses from defection. More tellingly, subjects direct their cooperative efforts preferentially towards defectors they have punished and away from those they haven't punished; they avoid expending punitive effort on reforming defectors who only pose a risk to others. These results are not consistent with the hypothesis that the psychology of punishment evolved to uphold group norms. The circumstances in which punishment is deployed and withheld-its circuit logic-support the hypothesis that it is generated by psychological mechanisms that evolved to benefit the punisher, by allowing him to bargain for better treatment.

The influence of corporate social responsibility, ability, reputation, and transparency on hotel customer loyalty in the U.S.: a gender-based approach.

This research explored a conceptual framework incorporating interrelationships among corporate social responsibility (CSR), corporate ability (CA), corporate reputation (CR), and CSR-related transparency on customer loyalty within the hotel context. In this study, we also analyzed consumers' propensity to support CSR initiatives through the socio-demographic indicator of gender. We used independent sample t test and multiple regression analysis to test hypotheses based on 487 responses from American participants. Four antecedents (i.e., CSR, CA, CR, and transparency) exhibited favorable effects on customer loyalty. Among these four factors, the positively perceived CSR initiatives had a greater impact on customer loyalty. In addition, according to our findings, female participants were more likely to have a positive perception of the four antecedents than males.

Learning to Be Unsung Heroes: Development of Reputation Management in Two Cultures.

Fu, Genyue; Heyman, Gail D; Lee, Kang

2016-05-01

The effective management of one's reputation is an important social skill, but little is known about how it develops. This study seeks to bridge the gap by examining how children communicate about their own good deeds, among 7- to 11-year-olds in both China and Canada (total N = 378). Participants cleaned a teacher's messy office in her absence, and their responses were observed when the teacher returned. Only the Chinese children showed an age-related increase in modesty by choosing to falsely deny their own good deeds. This modest behavior was uniquely predicted by Chinese children's evaluations of modesty-related lies. The results suggest that culture-specific socialization processes influence the way children communicate with authority figures about prosocial deeds. © 2016 The Authors.

The purposes of the present study were to: (1) describe rates of peer victimization in young adolescents with attention-deficit/hyperactivity disorder, (2) evaluate the association between types of peer victimization (i.e., physical, relational, and reputational) and internalizing problems (i.e., anxiety, depression, and self-esteem), and (3) examine whether associations between victimization and internalizing problems differ for males or females. Participants were 131 middle-school students (ages 11-15 years, 73 % male, 76 % White) diagnosed with ADHD who completed ratings of victimization, anxiety, depression, and self-esteem. Over half of the participants (57 %) reported experiencing at least one victimization behavior at a rate of once per week or more, with higher rates of relational victimization (51 %) than reputational victimization (17 %) or physical victimization (14 %). Males reported experiencing more physical victimization than females, but males and females did not differ in rates of relational or reputational victimization. Whereas relational and physical victimization were both uniquely associated with greater anxiety for both males and females, relational victimization was associated with greater depressive symptoms and lower self-esteem for males but not females. These findings indicate that young adolescents with ADHD frequently experience peer victimization and that the association between victimization and internalizing problems among young adolescents with ADHD differs as a result of victimization type, internalizing domain, and sex.

Partner switching promotes cooperation among myopic agents on a geographical plane

We study the coupling dynamics between the evolution of cooperation and the evolution of partnership network on a geographical plane. While agents play networked prisoner’s dilemma games, they can dynamically adjust their partnerships based on local information about reputation. We incorporate geographical features into the process of the agent’s partner switching and investigate the corresponding effects. At each time step of the coevolution, a random agent can either update his strategy by imitation or adjust his partnership by switching from the lowest reputation partner to the highest reputation one among his neighbors. We differentiate two types of neighbors: geographical neighbors (i.e., the set of agents who are close to the focal agent in terms of geographical distance) and connectivity neighbors (i.e., the set of agents who are close to the focal agent in the partnership network in terms of geodesic distance). We find that switching to either geographical neighbors or connectivity neighbors enhances cooperation greatly in a wide parameter range. Cooperation can be favored in a much stricter condition when agents switch to connectivity neighbors more frequently. However, an increasing tendency of reconnecting to geographical neighbors shortens the geographical distance between a pair of partners on average. When agents consider the cost of geographical distance in adjusting the partnership, they are prone to reconnect to geographical neighbors.

Automatic discrimination between safe and unsafe swallowing using a reputation-based classifier

PubMed Central

2011-01-01

Background Swallowing accelerometry has been suggested as a potential non-invasive tool for bedside dysphagia screening. Various vibratory signal features and complementary measurement modalities have been put forth in the literature for the potential discrimination between safe and unsafe swallowing. To date, automatic classification of swallowing accelerometry has exclusively involved a single-axis of vibration although a second axis is known to contain additional information about the nature of the swallow. Furthermore, the only published attempt at automatic classification in adult patients has been based on a small sample of swallowing vibrations. Methods In this paper, a large corpus of dual-axis accelerometric signals were collected from 30 older adults (aged 65.47 ± 13.4 years, 15 male) referred to videofluoroscopic examination on the suspicion of dysphagia. We invoked a reputation-based classifier combination to automatically categorize the dual-axis accelerometric signals into safe and unsafe swallows, as labeled via videofluoroscopic review. From these participants, a total of 224 swallowing samples were obtained, 164 of which were labeled as unsafe swallows (swallows where the bolus entered the airway) and 60 as safe swallows. Three separate support vector machine (SVM) classifiers and eight different features were selected for classification. Results With selected time, frequency and information theoretic features, the reputation-based algorithm distinguished between safe and unsafe swallowing with promising accuracy (80.48 ± 5.0%), high sensitivity (97.1 ± 2%) and modest specificity (64 ± 8.8%). Interpretation of the most discriminatory features revealed that in general, unsafe swallows had lower mean vibration amplitude and faster autocorrelation decay, suggestive of decreased hyoid excursion and compromised coordination, respectively. Further, owing to its performance-based weighting of component classifiers, the static reputation-based algorithm outperformed the democratic majority voting algorithm on this clinical data set. Conclusion Given its computational efficiency and high sensitivity, reputation-based classification of dual-axis accelerometry ought to be considered in future developments of a point-of-care swallow assessment where clinical informatics are desired.

Baldoni, Roberto; Doria, Luca; Lodi, Giorgia; Querzoni, Leonardo

In industry practice, bilateral agreements are established between providers and consumers of services in order to regulate their business relationships. In particular, Quality of Service (QoS) requirements are specified in those agreements in the form of legally binding contracts named Service Level Agreements (SLA). Meeting SLAs allows providers to be seen in the eyes of their clients, credible, reliable, and trustworthy. This contributes to augment their reputation that can be considered an important and competitive advantage for creating potentially new business opportunities.

Buyer feedback as a filtering mechanism for reputable sellers

2002-12-01

We propose a continuum model for the description of buyer and seller dynamics in an Internet market. The relevant variables are the research effort of buyers and the sellers’ reputation building process. We show that, if a commercial website gives consumers the possibility to rate credibly sellers they bargained with, vendors are forced to be more honest. This leads to mutual beneficial symbiosis between buyers and sellers; the overall enhanced volume of transactions contributes ultimately to the website, which facilitates the matchmaking service.

The social construction of ‘dowry deaths’

2015-01-01

The classification of cause of death is real in its consequences: for the reputation of the deceased, for her family, for those who may be implicated, and for epidemiological and social research and policies and practices that may follow from it. The study reported here refers specifically to the processes involved in classifying deaths of women from burns in India. In particular, it examines the determination of ‘dowry death’, a class used in India, but not in other jurisdictions. Classification of death is situated within a framework of special legal provisions intended to protect vulnerable women from dowry-related violence and abuse. The findings are based on 33 case studies tracked in hospital in real time, and interviews with 14 physicians and 14 police officers with experience of dealing with burns cases. The formal class into which any given death is allocated is shown to result from motivated accounting processes representing the interests and resources available to the doctors, victims, victim families, the victim’s husband and his family, and ultimately, the police. These processes may lead to biases in research and to injustice in the treatment of victims and alleged offenders. Suggestions are made for methods of ameliorating the risks. PMID:25129569

Application of an engineering problem-solving methodology to address persistent problems in patient safety: a case study on retained surgical sponges after surgery.

PubMed

Anderson, Devon E; Watts, Bradley V

2013-09-01

Despite innumerable attempts to eliminate the postoperative retention of surgical sponges, the medical error persists in operating rooms worldwide and places significant burden on patient safety, quality of care, financial resources, and hospital/physician reputation. The failure of countless solutions, from new sponge counting methods to radio labeled sponges, to truly eliminate the event in the operating room requires that the emerging field of health-care delivery science find innovative ways to approach the problem. Accordingly, the VA National Center for Patient Safety formed a unique collaboration with a team at the Thayer School of Engineering at Dartmouth College to evaluate the retention of surgical sponges after surgery and find a solution. The team used an engineering problem solving methodology to develop the best solution. To make the operating room a safe environment for patients, the team identified a need to make the sponge itself safe for use as opposed to resolving the relatively innocuous counting methods. In evaluation of this case study, the need for systematic engineering evaluation to resolve problems in health-care delivery becomes clear.

Mixed messages: An evaluation of NHS Trust Social Media policies in the North West of England.

2017-08-01

Despite National Health Service (NHS) information strategy promoting the use of Social Media (SoMe) to encourage greater engagement between service users and providers, a team investigating online SoMe interaction between breast screening practitioners and clients found that practitioners alleged discouragement from employers' policies. This study aimed to investigate whether this barrier was genuine, and illuminate whether local policy differed from national strategy. The study used a qualitative grounded theory approach to generate a theory. Nine policies from the North West of England were analysed. A framework was derived from the data, and an analysis of policy tone followed by a detailed coding of policy content was undertaken. Comparative analysis continued by reviewing the literature, and a condensed framework revealed five broad categories that policies addressed. The analysis revealed the policies varied in content, but not in tone, which was mostly discouraging. Coding the content revealed that the most frequently addressed point was that of protecting the employers' reputation, and after further analysis, the resultant condensed framework showed that policies were imbalanced and heavily skewed towards Security, Conduct & Behaviour and Reputation. Practitioners within breast screening services are discouraged by overly prohibitive and prescriptive SoMe policies; with these varying tremendously in comprehensiveness, but with a narrow focus on security and employers reputation; in contrast with national strategy. Recommendations are that policy revision is undertaken with consultation by more than one stakeholder, and SoMe training is offered for all members of NHS staff.

Shaped by asymmetrical interdependence: a qualitative case study of the external influences on international non-governmental organizations' implementation of equity principles in HIV/AIDS work.

Addressing inequities is a key role for international non-governmental organizations (INGOs) working in health and development. Yet, putting equity principles into practice can prove challenging. In-depth empirical research examining what influences INGOs' implementation of equity principles is limited. This study examined the influences on one INGO's implementation of equity principles in its HIV/AIDS programs. This research employed a case study with nested components (an INGO operating in Kenya, with offices in North America). We used multiple data collection methods, including document reviews, interviews (with staff, partners and clients of the INGO in Kenya), and participant observation (with Kenyan INGO staff). Participant observation was conducted with 10 people over three months. Forty-one interviews were completed, and 127 documents analyzed. Data analysis followed Auerbach and Silverstein's analytic process (2003), with qualitative coding conducted in multiple stages, using descriptive matrices, visual displays and networks (Miles and Huberman, 1994). There was a gap between the INGO's intent to implement equity principles and actual practice due to multiple influences from various players, including donors and country governments. The INGO was reliant on donor funding and needed permission from the Kenyan government to work in-country. Major influences included donor agendas and funding, donor country policies, and Southern country government priorities and legislation. The INGO privileged particular vulnerable populations (based on its reputation, its history, and the priorities of the Kenyan government and the donors). To balance its equity commitment with the influences from other players, the INGO aligned with the system as well as pushed back incrementally on the donors and the Kenyan government to influence these organizations' equity agendas. By moving its equity agenda forward incrementally and using its reputational advantage, the INGO avoided potential negative repercussions that might result from pushing too fast or working outside the system. The INGO aligned the implementation of equity principles in its HIV/AIDS initiatives by working within a system characterized by asymmetrical interdependence. Influences from the donors and Kenyan government contributed to an implementation gap between what the INGO intended to accomplish in implementing equity principles in HIV/AIDS work and actual practice.

Four outbreaks of Salmonella enteritidis phage type (PT) 4 occurred among guests at functions for which a single commercial caterer supplied food. Retrospective cohort studies were used to describe the epidemiology of three of these outbreaks and identify the vehicle(s) responsible. Of 172 guests at these three events, 47 fitted the clinical case definition for illness and 24 cases were confirmed to have S. enteritidis PT4 infection. Food containing raw egg was identified epidemiologically as the likely vehicle of infection in two of the three outbreaks (odds ratios (OR) and 95% confidence intervals 9.1 (2.2-39.9) and 6.9 (1.2-46.4)). Logistic regression analysis yielded OR = 10.7 (p = 0.0022) and OR = 9.3 (p = 0.015) for egg consumption in two of the outbreaks. These outbreaks highlighted the continuing need to remind the public and commercial caterers of the potential high risks of contracting salmonella from shell eggs. Education of caterers includes advice to obtain eggs and other products from reputable and identifiable suppliers.

2017-12-01

The aim of this research was to investigate specific determinants or factors that influence consumer online trust in the B2C e-commerce with a focus on consumers. Constructs such as perceived security, perceived privacy, perceived third party assurance, perceived reputation, perceived familiarity and perceived website quality and their relationship with online trust in the B2C context were studied. In conducting the research, a convenience sampling technique was adopted in carrying out the survey. Questionnaires were distributed to the target respondents and the data were analyzed using SPSS version 24. A Pearson's correlation was used to test the six hypotheses identified in this study. The results provided evidence that perceived security has the greatest influence on online trust. This was followed closely by perceived reputation and finally perceived privacy. This clearly shows that e-commerce consumer population considers these factors very imperative in engendering their trust in the virtual B2C e-commerce environment.

Although gossip serves several important social functions, it has relatively infrequently been the topic of systematic investigation. In two experiments, we advance a cognitive-informational approach to gossip. Specifically, we sought to determine which informational components engender gossip. In Experiment 1, participants read brief passages about other people and indicated their likelihood to share this information. We manipulated target familiarity (celebrity, non-celebrity) and story interest (interesting, boring). While participants were more likely to gossip about celebrity than non-celebrity targets and interesting than boring stories, they were even more likely to gossip about celebrity targets embedded within interesting stories. In Experiment 2, we additionally probed participants' reactions to the stories concerning emotion, expectation, and reputation information conveyed. Analyses showed that while such information partially mediated target familiarity and story interest effects, only expectation and reputation accounted for the interactive pattern of gossip behavior. Our findings provide novel insights into the essential components and processing mechanisms of gossip.

An Adaptive Reputation-Based Algorithm for Grid Virtual Organization Formation

NASA Astrophysics Data System (ADS)

Cui, Yongrui; Li, Mingchu; Ren, Yizhi; Sakurai, Kouichi

A novel adaptive reputation-based virtual organization formation is proposed. It restrains the bad performers effectively based on the consideration of the global experience of the evaluator and evaluates the direct trust relation between two grid nodes accurately by consulting the previous trust value rationally. It also consults and improves the reputation evaluation process in PathTrust model by taking account of the inter-organizational trust relationship and combines it with direct and recommended trust in a weighted way, which makes the algorithm more robust against collusion attacks. Additionally, the proposed algorithm considers the perspective of the VO creator and takes required VO services as one of the most important fine-grained evaluation criterion, which makes the algorithm more suitable for constructing VOs in grid environments that include autonomous organizations. Simulation results show that our algorithm restrains the bad performers and resists against fake transaction attacks and badmouth attacks effectively. It provides a clear advantage in the design of a VO infrastructure.

Application of the AHP method in modeling the trust and reputation of software agents

2016-06-01

Given the unique characteristics of cyberspace and, in particular, the number of inherent security threats, communication between software agents becomes a highly complex issue and a major challenge that, on the one hand, needs to be continuously monitored and, on the other, awaits new solutions addressing its vulnerabilities. An approach that has recently come into view mimics mechanisms typical of social systems and is based on trust and reputation that assist agents in deciding which other agents to interact with. The paper offers an enhancement to existing trust and reputation models, involving the application of the AHP method that is widely used for decision support in social systems, notably for risks analysis. To this end, it is proposed to expand the underlying conceptual basis by including such notions as self-trust and social trust, and to apply these to software agents. The discussion is concluded with an account of an experiment aimed at testing the effectiveness of the proposed solution.

The topography of generosity: asymmetric evaluations of prosocial actions.

PubMed

Klein, Nadav; Epley, Nicholas

2014-12-01

Prosociality is considered a virtue. Those who care for others are admired, whereas those who care only for themselves are despised. For one's reputation, it pays to be nice. Does it pay to be even nicer? Four experiments assess reputational inferences across the entire range of prosocial outcomes in zero-sum interactions, from completely selfish to completely selfless actions. We observed consistent nonlinear evaluations: Participants evaluated selfish actions more negatively than equitable actions, but they did not evaluate selfless actions markedly more favorably than equitable actions. This asymptotic pattern reflected monotonic evaluations for increasingly selfish actions and insensitivity to increasingly selfless actions. It pays to be nice but not to be really nice. Additional experiments suggest that this pattern stems partly from failing to make spontaneous comparisons between varying degrees of selflessness. We suggest that these reputational incentives could guide social norms, encouraging equitable actions but discouraging extremely selfless actions.

The Impact of the Internet on Health Consultation Market Concentration: An Econometric Analysis of Secondary Data

PubMed Central

2016-01-01

Background Many markets have traditionally been dominated by a few best-selling products, and this is also the case for the health care industry. However, we do not know whether the market will be more or less concentrated when health care services are delivered online (known as E-consultation), nor do we know how to reduce the concentration of the E-consultation market. Objective The aim of this study was to investigate the concentration of the E-consultation market and how to reduce its concentration through information disclosure mechanisms (online reputation and self-representation). Methods We employed a secondary data econometric analysis using transaction data obtained from an E-consultation Website (haodf.com) for three diseases (infantile pneumonia, diabetes, and pancreatic cancer) from 2008 to 2015. We included 2439 doctors in the analysis. Results The E-consultation market largely follows the 20/80 principle, namely that approximately 80% of orders are fulfilled by nearly 20% of doctors. This is much higher than the offline health care market. Meanwhile, the market served by doctors with strong online reputations (beta=0.207, P<.001) or strong online self-representation (beta=0.386, P<.001) is less concentrated. Conclusions When health care services are delivered online, the market will be more concentrated (known as the “Superstar” effect), indicating poor service efficiency for society as a whole. To reduce market concentration, E-consultation websites should provide important design elements such as ratings of doctors (user feedback), articles contributed by doctors, and free consultation services (online representation). A possible and important way to reduce the market concentration of the E-consultation market is to accumulate enough highly rated or highly self-represented doctors. PMID:27793793

Local health department leadership strategies for healthy built environments.

The built environment is an important but less-recognized health determinant, and local health departments need expanded guidance to address it. In such situations, leadership is particularly relevant. To assess whether and how local public and environmental health leaders increase their departments' health-promoting impact on built environment design, and what pitfalls they should avoid. Mixed-methods employing cross-sectional surveys and a comparative case study. Local public and environmental health departments. PARTICIPANTS SURVEY: A total of 159 (89%) health officers, health directors, and environmental health directors from all 62 local jurisdictions in California. Case-Study: Three departments, 12 cases, 36 health and land-use professionals, and 30 key informants. The study measured the influence of leadership practices on health departments' built environment-related collaborations, land use activities, policy developments, and contributions to physical changes. Quantitative multivariate linear and logistic regression were used. Case-study content analysis and pattern-matching, which related strong and weak leadership practices to outcomes, were also employed. Departments having highly innovative leaders with positive attitudes had greater odds of achieving physical changes to the built environment (OR: 4.5, 3.4, respectively). Leadership that most prepared their departments for built environment work (by updating staffing, structure, and strategy) tripled interagency and cross-sector collaboration (OR: 3.4). Leadership of successful departments consistently (1) established and managed a healthy built environment vision, (2) cultivated innovation, (3) supported, empowered and protected staff, (4) directly engaged in land use and transportation processes, (5) established direct contacts with directors in other departments, and (6) leveraged their professional reputation. Inconsistency in these practices was twice as common among failure as success cases (80%, 43%). Local health leadership underlies public and environmental health departments' community design efforts and should receive technical support and targeted resources to do so effectively.

Cooperation enhanced by indirect reciprocity in spatial prisoner's dilemma games for social P2P systems

Tian, Lin-Lin; Li, Ming-Chu; Wang, Zhen

2016-11-01

With the growing interest in social Peer-to-Peer (P2P) applications, relationships of individuals are further exploited to improve the performances of reputation systems. It is an on-going challenge to investigate how spatial reciprocity aids indirect reciprocity in sustaining cooperation in practical P2P environments. This paper describes the construction of an extended prisoner's dilemma game on square lattice networks with three strategies, i.e., defection, unconditional cooperation, and reciprocal cooperation. Reciprocators discriminate partners according to their reputations based on image scoring, where mistakes in judgment of reputations may occur. The independent structures of interaction and learning neighborhood are discussed, with respect to the situation in which learning environments differ from interaction networks. The simulation results have indicated that the incentive mechanism enhances cooperation better in structured peers than among a well-mixed population. Given the realistic condition of inaccurate reputation scores, defection is still successfully held down when the players interact and learn within the unified neighborhoods. Extensive simulations have further confirmed the positive impact of spatial structure on cooperation with different sizes of lattice neighborhoods. And similar conclusions can also be drawn on regular random networks and scale-free networks. Moreover, for the separated structures of the neighborhoods, the interaction network has a critical effect on the evolution dynamics of cooperation and learning environments only have weaker impacts on the process. Our findings further provide some insights concerning the evolution of collective behaviors in social systems.

A model for gossip-mediated evolution of altruism with various types of false information by speakers and assessment by listeners.

PubMed

Seki, Motohide; Nakamaru, Mayuko

2016-10-21

Indirect reciprocity is considered to be important for explaining altruism among humans. The evolution of altruism has been modeled using several types of reputational scores, most of which were assumed to be updated immediately after each game session. In this study, we introduce gossip sessions held between game sessions to capture the spread of reputation and examine the effects of false information intentionally introduced by some players. Analytical and individual-based simulation results indicated that the frequent exchange of gossip favored the evolution of altruism when no players started false information. In contrast, intermediate repetitions of gossip sessions were favored when the population included liars or biased gossipers. In addition, we found that a gossip listener's strategy of incorporating any gossip regardless of speakers usually worked better than an alternative strategy of not believing gossip from untrustworthy players.

Incentives to Encourage Scientific Web Contribution (Invited)

NASA Astrophysics Data System (ADS)

Antunes, A. K.

2010-12-01

We suggest improvements to citation standards and creation of remuneration opportunities to encourage career scientist contributions to Web2.0 and social media science channels. At present, agencies want to accomplish better outreach and engagement with no funding, while scientists sacrifice their personal time to contribute to web and social media sites. Securing active participation by scientists requires career recognition of the value scientists provide to web knowledge bases and to the general public. One primary mechanism to encourage participation is citation standards, which let a contributor improve their reputation in a quantifiable way. But such standards must be recognized by their scientific and workplace communities. Using case studies such as the acceptance of web in the workplace and the growth of open access journals, we examine what agencies and individual can do as well as the time scales needed to secure increased active contribution by scientists. We also discuss ways to jumpstart this process.

Classical bovine spongiform encephalopathy (c-BSE) is the only animal prion disease reputed to be zoonotic, causing variant Creutzfeldt-Jakob disease (vCJD) in humans and having guided protective measures for animal and human health against animal prion diseases. Recently, partial transmissions to humanized mice showed that the zoonotic potential of scrapie might be similar to c-BSE. We here report the direct transmission of a natural classical scrapie isolate to cynomolgus macaque, a highly relevant model for human prion diseases, after a 10-year silent incubation period, with features similar to those reported for human cases of sporadic CJD. Scrapie is thus actually transmissible to primates with incubation periods compatible with their life expectancy, although fourfold longer than BSE. Long-term experimental transmission studies are necessary to better assess the zoonotic potential of other prion diseases with high prevalence, notably Chronic Wasting Disease of deer and elk and atypical/Nor98 scrapie.

L’eggo My Ego: Reducing the Gender Gap in Math by Unlinking the Self from Performance

Zhang, Shen; Schmader, Toni; Hall, William M.

2012-01-01

Stereotype threat can vary in source, with targets being threatened at the individual and/or group level. This study examines specifically the role of self-reputational threat in women’s underperformance in mathematics. A pilot study shows that women report concerns about experiencing self-reputational threat that are distinct from group threat in the domain of mathematics. In the main study, we manipulated whether performance was linked to the self by asking both men and women to complete a math test using either their real name or a fictitious name. Women who used a fictitious name, and thus had their self unlinked from the math test, showed significantly higher math performance and reported less self-threat and distraction, relative to those who used their real names. Men were unaffected by the manipulation. These findings suggest that women’s impaired math performance is often due to the threat of confirming a negative stereotype as being true of the self. The implications for understanding the different types of threats faced by stereotyped groups, particularly among women in math settings, are discussed. PMID:24223027

The reliable operation of modern infrastructures depends on computerized systems and Supervisory Control and Data Acquisition (SCADA) systems, which are also based on the data obtained from sensor networks. The inherent limitations of the sensor devices make them extremely vulnerable to cyberwarfare/cyberterrorism attacks. In this paper, we propose a reputation system enhanced with distributed agents, based on unsupervised learning algorithms (self-organizing maps), in order to achieve fault tolerance and enhanced resistance to previously unknown attacks. This approach has been extensively simulated and compared with previous proposals.

Student plagiarism and professional practice.

PubMed

Kenny, Deborah

2007-01-01

With the ever-increasing availability and accessibility of the Internet, students are able to access a multitude of resources in support of their studies. However, this has also led to an increase in their ability to cheat through plagiarising text and claiming it as their own. Increased pressures of balancing work and study have contributed to this rise. Not only confined to the student population, some academics are also guilty of engaging in this practice providing a less than favourable role model for their students. Of increasing concern is the links of this practice to professionalism or indeed in this case unprofessionalism. Both pre- and post-registration nursing students who plagiarise risk bringing the reputation of the profession into disrepute. There are a number of methods that may be used to detect plagiarism but often the penalties are menial and inconsistently applied. Overall it is essential that academic institutions foster a culture of honesty and integrity amongst its academic community. A culture that clearly emphasises that plagiarism in any form is unacceptable.

Two distinct neural mechanisms underlying indirect reciprocity.

Cooperation is a hallmark of human society. Humans often cooperate with strangers even if they will not meet each other again. This so-called indirect reciprocity enables large-scale cooperation among nonkin and can occur based on a reputation mechanism or as a succession of pay-it-forward behavior. Here, we provide the functional and anatomical neural evidence for two distinct mechanisms governing the two types of indirect reciprocity. Cooperation occurring as reputation-based reciprocity specifically recruited the precuneus, a region associated with self-centered cognition. During such cooperative behavior, the precuneus was functionally connected with the caudate, a region linking rewards to behavior. Furthermore, the precuneus of a cooperative subject had a strong resting-state functional connectivity (rsFC) with the caudate and a large gray matter volume. In contrast, pay-it-forward reciprocity recruited the anterior insula (AI), a brain region associated with affective empathy. The AI was functionally connected with the caudate during cooperation occurring as pay-it-forward reciprocity, and its gray matter volume and rsFC with the caudate predicted the tendency of such cooperation. The revealed difference is consistent with the existing results of evolutionary game theory: although reputation-based indirect reciprocity robustly evolves as a self-interested behavior in theory, pay-it-forward indirect reciprocity does not on its own. The present study provides neural mechanisms underlying indirect reciprocity and suggests that pay-it-forward reciprocity may not occur as myopic profit maximization but elicit emotional rewards.

Thermal signatures of voluntary deception in ecological conditions

2016-01-01

Deception is a pervasive phenomenon that greatly influences dyadic, groupal and societal interactions. Behavioural, physiological and neural signatures of this phenomenon have imporant implications for theoretical and applied research, but, because it is difficult for a laboratory to replicate the natural context in which deception occurs, contemporary research is still struggling to find such signatures. In this study, we tracked the facial temperature of participants who decided whether or not to deceive another person, in situations where their reputation was at risk or not. We used a high-sensitivity infrared device to track temperature changes to check for unique patterns of autonomic reactivity. Using a region-of-interest based approach we found that prior to any response there was a minimal increase in periorbital temperature (which indexes sympathetic activation, together with reduced cheek temperature) for the self-gain lies in the reputation-risk condition. Crucially, we found a rise in nose temperature (which indexes parasympathetic activation) for self-gain lies in the reputation-risk condition, not only during response preparation but also after the choice was made. This finding suggests that the entire deception process may be tracked by the nose region. Furthermore, this nasal temperature modulation was negatively correlated with machiavellian traits, indicating that sympathetic/parasympathetic regulation is less important for manipulative individuals who may care less about the consequences of lie-related moral violations. Our results highlight a unique pattern of autonomic reactivity for spontaneous deception in ecological contexts. PMID:27734927

Memory for reputational trait information: is social-emotional information processing less flexible in old age?

PubMed

Bell, Raoul; Giang, Trang; Mund, Iris; Buchner, Axel

2013-12-01

How do younger and older adults remember reputational trait information about other people? In the present study, trustworthy-looking and untrustworthy-looking faces were paired with cooperation or cheating in a cooperation game. In a surprise source-memory test, participants were asked to rate the likability of the faces, and were required to remember whether the faces were associated with negative or positive outcomes. The social expectations of younger and older adults were clearly affected by a priori facial trustworthiness. Facial trustworthiness was associated with high cooperation-game investments, high likability ratings, and a tendency toward guessing that a face belonged to a cooperator instead of a cheater in both age groups. Consistent with previous results showing that emotional memory is spared from age-related decline, memory for the association between faces and emotional reputational information was well preserved in older adults. However, younger adults used a flexible encoding strategy to remember the social interaction partners. Source-memory was best for information that violated their (positive) expectations. Older adults, in contrast, showed a uniform memory bias for negative social information; their memory performance was not modulated by their expectations. This finding suggests that older adults are less likely to adjust their encoding strategies to their social expectations than younger adults. This may be in line with older adults' motivational goals to avoid risks in social interactions. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Building a patient-centered hospital web site: best practices in china.

PubMed

Huang, Edgar

2015-01-01

In this case study, based on six criteria, four Chinese hospitals were chosen from a national sample to showcase, through content analysis and in-depth interviews, the best practices of serving patients online. The extensive findings have addressed the following three questions: what these hospitals have in common in their Web development, what problems and challenges they are facing, and how they have excelled in serving their patients online. The study concludes that, like larger hospitals, smaller hospitals can also excel in creating an outstanding Web site to serve their patients so long as they truly care about their patients, have a clear vision and strong expertise in IT development. The study also concludes that Chinese private hospitals can learn from these state-owned hospitals in establishing a good reputation through professional and responsible interaction with patients. The four hospitals studied may shed light on the Web development in many other Chinese hospitals that are going through the same healthcare new media adoption. The findings from this study can also help Chinese hospitals form their visions in serving patients online.

Boachie, Micheal Kofi

2016-01-01

Background: In early 2012, National Health Insurance Scheme (NHIS) members in Ashanti Region were allowed to choose their own primary healthcare providers. This paper investigates the factors that enrolees in the Ashanti Region considered in choosing preferred primary healthcare providers (PPPs) and direction of association of such factors with the choice of PPP. Methods: Using a cross-sectional study design, the study sampled 600 NHIS enrolees in Kumasi Metro area and Kwabre East district. The sampling methods were a combination of simple random and systematic sampling techniques at different stages. Descriptive statistics were used to analyse demographic information and the criteria for selecting PPP. Multinomial logistic regression technique was used to ascertain the direction of association of the factors and the choice of PPP using mission PPPs as the base outcome. Results: Out of the 600 questionnaires administered, 496 were retained for further analysis. The results show that availability of essential drugs (53.63%) and doctors (39.92%), distance or proximity (49.60%), provider reputation (39.52%), waiting time (39.92), additional charges (37.10%), and recommendations (48.79%) were the main criteria adopted by enrolees in selecting PPPs. In the regression, income (-0.0027), availability of doctors (-1.82), additional charges (-2.14) and reputation (-2.09) were statistically significant at 1% in influencing the choice of government PPPs. On the part of private PPPs, availability of drugs (2.59), waiting time (1.45), residence (-2.62), gender (-2.89), and reputation (-2.69) were statistically significant at 1% level. Presence of additional charges (-1.29) was statistically significant at 5% level. Conclusion: Enrolees select their PPPs based on such factors as availability of doctors and essential drugs, reputation, waiting time, income, and their residence. Based on these findings, there is the need for healthcare providers to improve on their quality levels by ensuring constant availability of essential drugs, doctors, and shorter waiting time. However, individual enrolees may value each criterion differently. Thus, not all enrolees may be motivated by same concerns. This requires providers to be circumspect regarding the factors that may attract enrolees. The National Health Insurance Authority (NHIA) should also ensure timely release of funds to help providers procure the necessary medical supplies to ensure quality service PMID:26927586

Expert risk perceptions and the social amplification of risk: A case study in invasive tree pests and diseases.

PubMed

Urquhart, Julie; Potter, Clive; Barnett, Julie; Fellenor, John; Mumford, John; Quine, Christopher P

2017-11-01

The Social Amplification of Risk Framework (SARF) is often used as a conceptual tool for studying diverse risk perceptions associated with environmental hazards. While widely applied, it has been criticised for implying that it is possible to define a benchmark 'real' risk that is determined by experts and around which public risk perceptions can subsequently become amplified. It has been argued that this objectification of risk is particularly problematic when there are high levels of scientific uncertainty and a lack of expert consensus about the nature of a risk and its impacts. In order to explore this further, this paper examines how 'experts' - defined in this case as scientists, policy makers, outbreak managers and key stakeholders - construct and assemble their understanding of the risks associated with two invasive tree pest and disease outbreaks in the UK, ash dieback and oak processionary moth. Through semi-structured interviews with experts in each of the case study outbreaks, the paper aims to better understand the nature of information sources drawn on to construct perceptions of tree health risks, especially when uncertainty is prevalent. A key conclusion is that risk assessment is a socially-mediated, relational and incremental process with experts drawing on a range of official, anecdotal and experiential sources of information, as well as reference to past events in order to assemble the risk case. Aligned with this, experts make attributions about public concern, especially when the evidence base is incomplete and there is a need to justify policy and management actions and safeguard reputation.

The Business Case for Preconception Care: Methods and Issues

PubMed Central

Sotnikov, Sergey V.; Leatherman, Sheila; Curtis, Michele

2006-01-01

Only a limited number of economic evaluations have addressed the costs and benefits of preconception care. In order to persuade health care providers, payers, or purchasers to become actively involved in promoting preconception care, it is important to demonstrate the value of doing so through development of a “business case”. Perceived benefits in terms of organizational reputation and market share can be influential in forming a business case. In addition, it is standard to include an economic analysis of financial costs and benefits from the perspective of the provider practice, payer, or purchaser in a business case. The methods, data needs, and other issues involved with preparing an economic analysis of the likely financial return on investment in preconception care are presented here. This is accompanied by a review or case study of economic evaluations of preconception care for women with recognized diabetes. Although the data are not sufficient to draw firm conclusions, there are indications that such care may yield positive financial benefits to health care organizations through reduction in maternal and infant hospitalizations. More work is needed to establish how costs and economic benefits are distributed among different types of organizations. Also, the optimum methods of delivering preconception care for women with diabetes need to be evaluated. Similar assessments should also be conducted for other forms of preconception care, including comprehensive care. PMID:16786418

Selfish or selfless? On the signal value of emotion in altruistic behavior.

PubMed

Barasch, Alixandra; Levine, Emma E; Berman, Jonathan Z; Small, Deborah A

2014-09-01

Theories that reject the existence of altruism presume that emotional benefits serve as ulterior motives for doing good deeds. These theories argue that even in the absence of material and reputational benefits, individuals reap utility from the feelings associated with doing good. In response to this normative view of altruism, this article examines the descriptive question of whether laypeople penalize emotional prosocial actors. Six studies find that emotion serves as a positive signal of moral character, despite the intrapsychic benefits associated with it. This is true when emotion motivates prosocial behavior (Studies 1, 2, 3, and 5) and when emotion is a positive outcome of prosocial behavior (i.e., "warm glow"; Studies 4, 5, and 6). Emotional actors are considered to be moral because people believe emotion provides an honest and direct signal that the actor feels a genuine concern for others. Consequently, prosocial actors who are motivated by the expectation of emotional rewards are judged differently than prosocial actors who are motivated by other benefits, such as reputational or material rewards (Study 6). These results suggest that laypeople do not view altruism as incompatible with all benefits to the self. 2014 APA, all rights reserved

Recruiting medical groups for research: relationships, reputation, requirements, rewards, reciprocity, resolution, and respect

Background In order to conduct good implementation science research, it will be necessary to recruit and obtain good cooperation and comprehensive information from complete medical practice organizations. The goal of this paper is to report an effective example of such a recruitment effort for a study of the organizational aspects of depression care quality. Methods There were 41 medical groups in the Minnesota region that were eligible for participation in the study because they had sufficient numbers of patients with depression. We documented the steps required to both recruit their participation in this study and obtain their completion of two questionnaire surveys and two telephone interviews. Results All 41 medical groups agreed to participate and consented to our use of confidential data about their care quality. In addition, all 82 medical directors and quality improvement coordinators completed the necessary questionnaires and interviews. The key factors explaining this success can be summarized as the seven R's: Relationships, Reputation, Requirements, Rewards, Reciprocity, Resolution, and Respect. Conclusion While all studies will not have all of these factors in such good alignment, attention to them may be important to other efforts to add to our knowledge of implementation science.

Metareasoning and Social Evaluations in Cognitive Agents

NASA Astrophysics Data System (ADS)

Pinyol, Isaac; Sabater-Mir, Jordi

Reputation mechanisms have been recognized one of the key technologies when designing multi-agent systems. They are specially relevant in complex open environments, becoming a non-centralized mechanism to control interactions among agents. Cognitive agents tackling such complex societies must use reputation information not only for selecting partners to interact with, but also in metareasoning processes to change reasoning rules. This is the focus of this paper. We argue about the necessity to allow, as a cognitive systems designers, certain degree of freedom in the reasoning rules of the agents. We also describes cognitive approaches of agency that support this idea. Furthermore, taking as a base the computational reputation model Repage, and its integration in a BDI architecture, we use the previous ideas to specify metarules and processes to modify at run-time the reasoning paths of the agent. In concrete we propose a metarule to update the link between Repage and the belief base, and a metarule and a process to update an axiom incorporated in the belief logic of the agent. Regarding this last issue we also provide empirical results that show the evolution of agents that use it.

When a population is engaged in successive prisoner's dilemmas, indirect reciprocity through reputation fosters cooperation through the emergence of moral and action rules. A simplified model has recently been proposed where individuals choose between helping others or not and are judged good or bad for it by the rest of the population. The reputation so acquired will condition future actions. In this model, eight strategies (referred to as "leading eight") enforce a high level of cooperation, generate high payoffs, and are therefore resistant to invasions by other strategies. Here we show that, by assigning each individual one of two labels that peers can distinguish (e.g., political ideas, religion, and skin color) and allowing moral and action rules to depend on the label, intolerant behaviors can emerge within minorities under sufficient economic stress. We analyze the sets of conditions where this can happen and also discuss the circumstances under which tolerance can be restored. Our results agree with empirical observations that correlate intolerance and economic stress and predict a correlation between the degree of tolerance of a population and its composition and ethical stance.

"Stay cool, sell stuff cheap, and smile": Examining how reputational management of dental tourism reinforces structural oppression in Los Algodones, Mexico.

Los Algodones, Mexico is characteristic of other medical border towns whose proximity to the Mexico-United States border enables American and Canadian patients to take advantage of economic asymmetries on either side of the border to access desired health care. Los Algodones is unique, however, in its focus on the provision of dental care and claims by local residents that it has the highest concentration of dentists per capita in the world. In this paper, we present an analysis of interviews with employees working in Los Algodones' dental tourism industry to examine interviewees' participation in practices related to reputational management of the industry site. Drawing on our interview discussions, we argue that many of these reputational management practices reinforce structural injustices and raise concerns for structural exploitation in the industry. This analysis nuances ethical considerations for medical tourism by highlighting structural factors informing unjust practices within the industry, factors which might be relevant to other medical tourism contexts.

Charles Darwin's reputation: how it changed during the twentieth-century and how it may change again.

PubMed

Amundson, Ron

2014-01-01

Charles Darwin died in 1882. During the twentieth century his reputation varied through time, as the scientific foundation of evolutionary theory changed. Beginning the century as an intellectual hero, he soon became a virtual footnote as experimental approaches to evolution began to develop. As the Modern Synthesis developed his reputation began to rise again until eventually he was identified as a founding father of the Modern Synthesis itself. In the meantime, developmental approaches to evolution began to challenge certain aspects of the Modern Synthesis. Synthesis authors attempted to refute the relevance of development by methodological arguments, some of them indirectly credited to Darwin. By the end of the century, molecular genetics had given new life to development approaches to evolution, now called evo devo. This must be seen as a refutation of the aforesaid methodological arguments of the Modern Synthesis advocates. By the way, we can also see now how the historiography that credited Darwin with the Synthesis was in error. In conclusion, one more historical revision is suggested. Copyright © 2014 Elsevier Ltd.

“He Must Die or Go Mad in This Place”:

PubMed Central

Cox, Catherine; Marland, Hilary

2018-01-01

summary The relationship between prisons and mental illness has preoccupied prison administrators, physicians, and reformers from the establishment of the modern prison service in the nineteenth century to the current day. Here we take the case of Pentonville Model Prison, established in 1842 with the aim of reforming convicts through religious exhortation, rigorous discipline and training, and the imposition of separate confinement in its most extreme form. Our article demonstrates how following the introduction of separate confinement, the prison chaplains rather than the medical officers took a lead role in managing the minds of convicts. However, instead of reforming and improving prisoners’ minds, Pentonville became associated with high rates of mental disorder, challenging the institution’s regime and reputation. We explore the role of chaplains, doctors, and other prison officers in debating, disputing, and managing cases of mental breakdown and the dismantling of separate confinement in the face of mounting criticism.

Death in dental clinic: Indian scenario

PubMed Central

Seshappa, Kedarnath Nakkalahalli; Rangaswamy, Shruthi

2016-01-01

Deaths during dental treatment or as a result of dental treatment are rare, but the unfortunate fact is that such deaths do occur. Unexpected death of a patient can be emotionally draining and even harrowing to his or her relatives. The death of a patient may bring an enormous feeling of anxiety both at the personal and professional level, stress, profound grief, damage to self-esteem, loss of self-confidence, reputation, and specter of litigation on a dental surgeon. No dentist can be guaranteed to be free of such an incident during the course of his or her practice. The dentist should respond in a compassionate and respectful manner in case of such unfortunate tragic events, and also ensure self-protection. This article emphasizes on prevention of such incidents and throws some light on how to respond in case of an unfortunate death in a dental clinic, including the medico-legal aspects. PMID:27555720

[Animal welfare and corporate welfare in pharmaceutical R&D - the future of third-party assessment].

PubMed

Suzuki, Makoto

For research and development (R&D) of new drugs, animal experimentation is indispensable, and research institutes, pharmaceutical companies, or contract research organizations routinely conduct preclinical studies of efficacy, safety, or metabolism using laboratory animals. However, animal experimentation entails some organizational risks. One is the suspension of R&D of a new drug, because in the course of clinical studies it becomes apparent that the drug has limited efficacy, unexpected side effects, and/or unexpected metabolites. Another risk is damage to the company image by development of an unfavorable reputation. Society has accepted animal experimentation as a necessary evil, but if such experimentation is not conducted with adequate concern for animal welfare, social sanctions will against that institute, company or organization will result. Once this happens, it is difficult to recover a good public image. Therefore, pharmaceutical companies must conduct animal experiments so as to obtain highly useful data without sacrificing public favor. One way to maintain a good reputation is through third-party accreditation, which verifies that the institute, company or organization and its researchers value animal welfare appropriately.

Pharmaceutical patenting and the transformation of American medical ethics.

PubMed

Gabriel, Joseph M

2016-12-01

The attitudes of physicians and drug manufacturers in the US toward patenting pharmaceuticals changed dramatically from the mid-nineteenth century to the mid-twentieth. Formerly, physicians and reputable manufacturers argued that pharmaceutical patents prioritized profit over the advancement of medical science. Reputable manufactures refused to patent their goods and most physicians shunned patented products. However, moving into the early twentieth century, physicians and drug manufacturers grew increasingly comfortable with the idea of pharmaceutical patents. In 1912, for example, the American Medical Association dropped the prohibition on physicians holding medical patents. Shifts in wider patenting cultures therefore transformed the ethical sensibilities of physicians.

Cooperation based dynamic team formation in multi-agent auctions

NASA Astrophysics Data System (ADS)

Pippin, Charles E.; Christensen, Henrik

2012-06-01

Auction based methods are often used to perform distributed task allocation on multi-agent teams. Many existing approaches to auctions assume fully cooperative team members. On in-situ and dynamically formed teams, reciprocal collaboration may not always be a valid assumption. This paper presents an approach for dynamically selecting auction partners based on observed team member performance and shared reputation. In addition, we present the use of a shared reputation authority mechanism. Finally, experiments are performed in simulation on multiple UAV platforms to highlight situations in which it is better to enforce cooperation in auctions using this approach.

Helmholtz and Zoellner: nineteenth-century empiricism, spiritism, and the theory of space perception.

PubMed

Stromberg, W H

1989-10-01

J. K. F. Zoellner began writing on "experimental proofs" of a fourth spatial dimension, and of the existence of spirits, in 1878. His arguments caused strong controversy, with rebuttal essays by Wilhelm Wundt and others. The author argues that Zoellner's case that these matters are experimental questions rested on arguments which Hermann von Helmholtz, inveighing against rationalist views of space and space perception, had recently published. Zoellner's use of Helmholtz's arguments to advance and defend his spiritist views occasioned strong criticism of Helmholtz, affected careers and reputations of scholars in Berlin and Leipzig, and caused enduring controversy over the credibility of Helmholtz's empiricist theory of space perception.

Root Canal Treatment of Mandibular Second Premolar with Three Separate Roots and Canals Using Spiral Computed Tomographic

PubMed Central

Hariharavel, V. P.; Kumar, A. Ashok; Ganesh, C.; Aravindhan, R.

2014-01-01

Anatomic and internal morphology of a root canal system is more complex and differs for each individual tooth of which mandibular premolars have earned the reputation for having aberrant anatomy. The occurrence of three canals with three separate foramina in mandibular second premolars is very rare. A wider knowledge on both clinical and radiological anatomy especially spiral computed tomographic is absolutely essential for the success of endodontic treatment. These teeth may require skillful and special root canal special shaping and obturating techniques. This paper reports an unusual case of a mandibular second premolar with atypical canal pattern that was successfully treated endodontically. PMID:25101187

Investigation of source location determination from Magsat magnetic anomalies: The Euler method approach

NASA Technical Reports Server (NTRS)

Ravat, Dhananjay

1996-01-01

The applicability of the Euler method of source location determination was investigated on several model situations pertinent to satellite-data scale situations as well as Magsat data of Europe. Our investigations enabled us to understand the end-member cases for which the Euler method will work with the present satellite magnetic data and also the cases for which the assumptions implicit in the Euler method will not be met by the present satellite magnetic data. These results have been presented in one invited lecture at the Indo-US workshop on Geomagnetism in Studies of the Earth's Interior in August 1994 in Pune, India, and at one presentation at the 21st General Assembly of the IUGG in July 1995 in Boulder, CO. A new method, called Anomaly Attenuation Rate (AAR) Method (based on the Euler method), was developed during this study. This method is scale-independent and is appropriate to locate centroids of semi-compact three dimensional sources of gravity and magnetic anomalies. The method was presented during 1996 Spring AGU meeting and a manuscript describing this method is being prepared for its submission to a high-ranking journal. The grant has resulted in 3 papers and presentations at national and international meetings and one manuscript of a paper (to be submitted shortly to a reputable journal).

The social construction of 'dowry deaths'.

PubMed

Belur, Jyoti; Tilley, Nick; Daruwalla, Nayreen; Kumar, Meena; Tiwari, Vinay; Osrin, David

2014-10-01

The classification of cause of death is real in its consequences: for the reputation of the deceased, for her family, for those who may be implicated, and for epidemiological and social research and policies and practices that may follow from it. The study reported here refers specifically to the processes involved in classifying deaths of women from burns in India. In particular, it examines the determination of 'dowry death', a class used in India, but not in other jurisdictions. Classification of death is situated within a framework of special legal provisions intended to protect vulnerable women from dowry-related violence and abuse. The findings are based on 33 case studies tracked in hospital in real time, and interviews with 14 physicians and 14 police officers with experience of dealing with burns cases. The formal class into which any given death is allocated is shown to result from motivated accounting processes representing the interests and resources available to the doctors, victims, victim families, the victim's husband and his family, and ultimately, the police. These processes may lead to biases in research and to injustice in the treatment of victims and alleged offenders. Suggestions are made for methods of ameliorating the risks.

Disadvantaged persons' participation in health promotion projects: some structural dimensions.

PubMed

Boyce, W F

2001-05-01

A structural perspective was used in studying community participation of disadvantaged groups (poor women, street youth, and disabled persons) in health promotion projects. Five community projects in the Canadian Health Promotion Contribution Program were examined in a comparative case study utilizing in-depth interviews, documents, and secondary sources. Analysis revealed relatively low numbers and restricted range of participants, difficulties in recruiting and maintaining participants, declining rates of active participation over time, and limited target group influence and power. This paper reports on the relationship between various dimensions of structure (social-cultural, organizational, political-legal-economic) and the community participation process. Participation was influenced by structural factors such as bureaucratic rules and regulators, perceived minority group rights and relations, agency reputations and responsibilities, available resources, and organizational roles. Control of projects by target group members, rather than by service agencies, was an important overall organizational structural factor which allowed community members to achieve influence in projects. The study concludes that a conceptual model based on structural factors is useful in explaining how key factors from federal and local levels can restrict or facilitate the community participation process.

Stigma, deforming metaphors and patients' moral experience of multibacillary leprosy in Sobral, Ceará State, Brazil.

PubMed

Nations, Marilyn K; Lira, Geison Vasconcelos; Catrib, Ana Maria Fontenelle

2009-06-01

In response to the call for a new Science of Stigma, this anthropological study investigates the moral experience of patients diagnosed with severe multibacillary leprosy. From 2003 to 2006, fieldwork was conducted in the so-called 'United-States-of-Sobral', in Ceará State, Northeast Brazil. Sobral is highly endemic for leprosy, despite intensified eradication efforts and a 30% increase in primary care coverage since 1999. Of 329 active leprosy cases at two public clinics, 279 multibacillary patients were identified and six information-rich cases selected for in-depth ethnographic analysis, utilizing illness narratives, key-informant interviews, home visits, participant-observation of clinical consultations and semi-structured interviews with physicians. A 'contextualized semantic interpretation' revealed four leprosy metaphors: a repulsive rat's disease, a racist skin rash, a biblical curse and lethal leukemia. Far from value-free pathology, the disease is imbued with moral significance. Patients' multivocalic illness constructions contest physicians' disease discourse. 'Skin Spot Day' discriminates more than educates. Patients' 'non-compliance' with effective multi-drug therapy is due to demoralizing stigma more than a rejection of care. 'Social leprosy' in Northeast Brazil deforms patients' moral reputations and personal dignity.

Richard Doll and Alice Stewart: reputation and the shaping of scientific "truth".

PubMed

Greene, Gayle

2011-01-01

As the world watched the Fukushima reactors release radionuclides into the ocean and atmosphere, the warnings of Dr. Alice Stewart about radiation risk and the reassurances of Sir Richard Doll assumed renewed relevance. Doll and Stewart, pioneer cancer epidemiologists who made major contributions in the 1950s-he by demonstrating the link between lung cancer and smoking, she by discovering that fetal X-rays double the chance of a childhood cancer-were locked into opposition about low-dose radiation risk. When she went public with the discovery that radiation at a fraction of the dose "known" to be dangerous could kill a child, her reputation plummeted, whereas Doll, foremost among her detractors, was knighted and lauded as "the world's most distinguished medical epidemiologist" for his work. Their lives and careers, so closely intertwined, took contrary courses, he becoming "more of the establishment" (as he said), while she became more oppositional. When it was discovered, after his death, that he'd been taking large sums of money from industries whose chemicals he was clearing of cancer risk, his reputation remained unscathed; it is now enshrined in the "Authorized Biography" (2009) commissioned by the Wellcome Institute, along with Doll's denigration of Stewart as an "embittered" woman and biased scientist. Stewart lived long enough to see radiation science move her way, to see international committees affirm, in the 1990s, that there is no threshold beneath which radiation ceases to be dangerous; recent evidence from Chernobyl is bearing out her warnings. But a look at the making and breaking of these reputations reveals the power of status, position, and image to shape scientific "knowledge" and social policy.

The role of early maturation, perceived popularity, and rumors in the emergence of internalizing symptoms among adolescent girls.

PubMed

Reynolds, Bridget M; Juvonen, Jaana

2011-11-01

Despite the widely reported link between early pubertal timing and internalizing symptoms among girls, less is known about the peer reputation of earlier maturing girls. The current study assesses whether early maturation is associated with perceived popularity and/or rumors, and whether these reputational factors help account for earlier maturing girls' vulnerability to emotional distress. Drawing on three waves of data collected from an ethnically diverse sample of middle school girls (n = 912), hierarchical multiple regression analyses revealed that more advanced development at the start of middle school predicted peer- and teacher-reported popularity as well as increased risk of being targeted for rumors. Mediation analyses suggested that popularity among boys can put earlier developing girls at risk for rumors. Finally, rumors acted as a partial mechanism through which early maturation was associated with subsequent internalizing symptoms. Knowledge of the peer mechanisms putting earlier developing girls at risk for psychosocial maladjustment can inform intervention and prevention efforts aimed at improving adolescent well-being.

Factors influencing physicians' knowledge sharing on web medical forums.

PubMed

Lin, Tung Cheng; Lai, Ming Cheng; Yang, Shu Wen

2016-09-01

Web medical forums are relatively unique as knowledge-sharing platforms because physicians participate exclusively as knowledge contributors and not as knowledge recipients. Using the perspective of social exchange theory and considering both extrinsic and intrinsic motivations, this study aims to elicit the factors that significantly influence the willingness of physicians to share professional knowledge on web medical forums and develops a research model to explore the motivations that underlie physicians' knowledge-sharing attitudes. This model hypothesizes that constructs, including shared vision, reputation, altruism, and self-efficacy, positively influence these attitudes and, by extension, positively impact knowledge-sharing intention. A conventional sampling method and the direct recruitment of physicians at their outpatient clinic gathered valid data from a total of 164 physicians for analysis in the model. The empirical results support the validity of the proposed model and identified shared vision as the most significant factor of influence on knowledge-sharing attitudes, followed in descending order by knowledge-sharing self-efficacy, reputation, and altruism. © The Author(s) 2015.

Effects of Peer Academic Reputation on Achievement in Academically At-Risk Elementary Students

PubMed Central

Hughes, Jan N.; Dyer, Nicole; Luo, Wen; Kwok, Oi-Man

2008-01-01

Participants were 664 relatively low achieving children who were recruited into a longitudinal study when in first grade. Measures of peer academic reputation (PAR), peer acceptance, teacher-rated academic engagement and achievement, and reading and math achievement were obtained in Year 2, when the majority of students were in second grade, and 1 year later. Measures of academic self concept were obtained in Year 1 and in Year 3. As young as second grade, children’s perceptions of classmates’ academic competence are distinct from their perceptions of peers’ other social and behavioral characteristics. SEM analyses found that Year 2 PAR predicted Year 3 teacher-rated academic engagement and reading (but not math) achievement test scores, above the effects of prior scores on these outcomes and other covariates. Furthermore, the effect of PAR on academic engagement and achievement was partially mediated by the effect of PAR on children’s academic self concept. Implications of these findings for educational practice and future research are discussed. PMID:19617931

Stanley, Caroline; Conroy, Rowena; Long, Kristin A.; Fairclough, Diane L.; Kazak, Anne E.; Noll, Robert B.

2015-01-01

Objective This study examined social functioning among siblings of children with cancer. Method A case–control design was applied to school- and home-based data from multiple informants (peers, teachers, mothers, and self). Social reputation and peer acceptance within the classroom was compared for 87 siblings (aged 8–16 years) and 256 demographically matched peers. Self-perceptions of peer relationships and parent-reported social competence were examined among 67 siblings and 67 matched comparisons.  Results Peer reports (N = 1,633) indicated no differences between siblings and comparisons for social reputation, number of friendships, reciprocated friendships, or peer acceptance. Self-reported prosocial behavior and teacher-reported likability were higher for siblings than comparisons. Self-reported loneliness, friendship quality, and perceived social support did not differ between groups. Mothers reported less involvement in activities and poorer school performance for siblings than comparisons. Conclusions Peer relationships of siblings of children with cancer are similar to classmates, though they experience small decrements in activity participation and school performance.

2016-04-01

Cervical cancer is the third most common cancer worldwide. Accurate information about cervical cancer to general public can lower the burden of the disease including its mortality. We aimed to look at the quality of information available in YouTube for cervical cancer. We searched YouTube (http://www.youtube.com) for videos using the keyword Cervical cancer on November 12, 2015. Videos were then analyzed for their source and content of information. We studied 172 videos using the keyword Cervical cancer on November 12, 2015. We found that there were videos describing the personal stories, risk factors, and the importance of screening. However, videos discussing all the aspects of cancers were lacking. Likewise, videos from the reputed organization were also lacking. Although there were numerous videos available in cervical cancer, videos from reputed organizations including Center for Disease Control and Prevention, American Cancer Society, and World Health Organization were lacking. We strongly believe that quality videos from such organizations via YouTube can help lower the burden of disease.

Marketing and reputation aspects of neonatal safeguards and hospital-security systems.

Smith, Alan D

2009-01-01

Technological advancements have migrated from personal-use electronics into the healthcare setting for security enhancements. Within maternity wards and nurseries, technology was seen as one of best way to protect newborns from abduction. The present study is a focus on what systems and methods are used in neonatal security, the security arrangements, staff training, and impacts outside the control of the hospital, customer satisfaction and customer relations management. Through hypothesis-testing and exploratory analysis, gender biases and extremely high levels of security were found within a web-enabled and professional sample of 200 respondents. The factor-based constructs were found to be, in order of the greatest explained variance: security concerns, personal technology usage, work technology applications, and demographic maturity concerns, resulting in four factor-based scores with significant combined variance of 61.5%. It was found that through a better understanding on the importance and vital need for hospitals to continue to improve on their technology-based security policies significantly enhanced their reputation in the highly competitive local healthcare industry.

Streptomycin, Schatz v. Waksman, and the balance of credit for discovery.

PubMed

Kingston, William

2004-07-01

A recent article in Nature, arguing that "the misallocation of credit is endemic in science," used Selman Waksman as an illustration, claiming that the true discoverer of streptomycin was one of his graduate students. The article received wide publicity and seriously damaged Waksman's great reputation. What actually happened was that the success of penicillin stimulated Merck to fund research by Waksman, a soil scientist, into the collection of actinomycetes that he had assembled over thirty years. He applied the systematic, uncreative testing techniques that had made the German pharmaceutical industry so successful to these, and streptomycin was discovered within a matter of months. Work in the Mayo Institute then showed that it was marvelously effective against tuberculosis, and Waksman received the Nobel Prize for it in 1952. The test that turned out to be the crucial one could have been carried out by any of several students, but the lucky one was Albert Schatz. He then sued the university for a share of the royalties payable by Merck and also petitioned the Nobel committee to include him in the award. Although he obtained a very substantial out-of-court settlement, this probably damaged his subsequent academic career, and he has never ceased to argue his case for recognition, of which the Nature article is a reflection. To claim that Waksman took credit properly due to Schatz is to fail to understand that once pharmaceutical research had become primarily a matter of large-scale, routine testing, little individual creativity was left in this work. Credit for any successful results must therefore be given to whoever is the originator or director of a particular program. Nature refused to publish evidence that this case could not be used as an example of misallocation of credit for discovery. This in itself illustrates that editors of scientific journals should be every bit as mindful of scientists' reputations as they are of scientific facts.

Beyond reputation: debate on the role of corporate influence in occupational and environmental medicine.

PubMed

Bohme, Susanna Rankin; Egilman, David

2008-01-01

In his article in this issue, Tee Guidotti casts recent works addressing corporate influence on occupational medicine as "collective act[s] of disparagement ... undertaken ... for political reasons." We move beyond the question of reputation to address key conflicts in the history of occupational medicine, including the American Occupational Medical Association's historical role in weakening the beryllium standard and the American College of Occupational and Environmental Medicine's recent efforts to limit the extent of the Family Medical Leave Act. The corporate practice of externalizing health and safety costs makes industry influence an important ongoing topic of debate in occupational and environmental medicine.

Security in MANETs using reputation-adjusted routing

Mobile Ad-Hoc Networks enable communication in various dynamic environments, including military combat operations. Their open and shared communication medium enables new forms of attack that are not applicable for traditional wired networks. Traditional security mechanisms and defense techniques are not prepared to cope with the new attacks and the lack of central authorities make identity verifications difficult. This work extends our previous work in the Biologically Inspired Tactical Security Infrastructure to provide a reputation-based weighing mechanism for linkstate routing protocols to protect the network from attackers that are corrupting legitimate network traffic. Our results indicate that the approach is successful in routing network traffic around compromised computers.

Double Cluster Heads Model for Secure and Accurate Data Fusion in Wireless Sensor Networks

PubMed Central

Fu, Jun-Song; Liu, Yun

2015-01-01

Secure and accurate data fusion is an important issue in wireless sensor networks (WSNs) and has been extensively researched in the literature. In this paper, by combining clustering techniques, reputation and trust systems, and data fusion algorithms, we propose a novel cluster-based data fusion model called Double Cluster Heads Model (DCHM) for secure and accurate data fusion in WSNs. Different from traditional clustering models in WSNs, two cluster heads are selected after clustering for each cluster based on the reputation and trust system and they perform data fusion independently of each other. Then, the results are sent to the base station where the dissimilarity coefficient is computed. If the dissimilarity coefficient of the two data fusion results exceeds the threshold preset by the users, the cluster heads will be added to blacklist, and the cluster heads must be reelected by the sensor nodes in a cluster. Meanwhile, feedback is sent from the base station to the reputation and trust system, which can help us to identify and delete the compromised sensor nodes in time. Through a series of extensive simulations, we found that the DCHM performed very well in data fusion security and accuracy. PMID:25608211

Difficult reputations and the social reality of occupational medicine.

PubMed

Draper, Elaine

2008-01-01

This response to Tee Guidotti's (2008) critique of Elaine Draper's 'The Company Doctor: Risk, Responsibility, and Corporate Professionalism' (2003) argues that a forthright examination of the conflicts of those working in the field of occupational medicine is essential to maintaining the health of the profession and to promoting constructive policies. Research for 'The Company Doctor' reveals how doctors walk a tightrope of professional demands on them. The author describes how corporate employment affects medicine and science and how professionals working in corporations are subject to the decisions of company managers and to economic and legal imperatives stemming from their status as corporate employees. Analyzing company doctors' role in confronting toxics and responding to liability fears in corporations, the author argues that problems of lost credibility, stigmatization, and tarnished reputation that company doctors describe largely stem from the organizational constraints, economic interests, and other aspects of the social context of their work. These social forces exert powerful pressure on the ethical framework and daily work lives of these professionals as well as on the reputation of their field. The author discusses ways in which the conflicting demands from being both a corporate employee and a physician are a social and structural problem beyond individual ethics.
