Measuring particularized trust: A name generator approach

In the social sciences, trust scholars largely divide their interests between two streams of research: one on generalized trust and one on particularized trust. While recent developments in the measurement of generalized trust have pushed the literature forward, similar improvements to the measurement of particularized trust have lagged behind. In this article, I advance trust research by (1) developing an egocentric particularized trust (EPT) instrument based on a multiple name generator approach, and (2) assessing EPT’s empirical performance across numerous psychometric tests. Results from a general population quota sample (N = 2041) indicate that EPT consists of two separate latent constructs, one for personally known others (EPT-K) and one for family members (EPT-F). Using traditional measures of particularized trust as benchmarks, I find that EPT-K and EPT-F provide the most valid and reliable measures of particularized trust. I conclude by discussing implications and directions for future research.     

Sex differences in trust and trustworthiness: A meta-analysis of the trust game and the gift-exchange game

We present a meta-analytic review of the literature on sex differences in the trust game (174 effect sizes) and the related gift-exchange game (35 effect sizes). Based on parental investment theory and social role theory we expected men to be more trusting and women to be more trustworthy. Indeed, men were more trusting in the trust game (g = 0.22), yet we found no significant sex difference in trust in the gift-exchange game (g = 0.15). Regarding trustworthiness, we found no significant sex difference in the trust game (g = −0.04), and we found men, not women, to be more trustworthy in the gift-exchange game (g = 0.33). These results suggest that men send more money than women do when their money is going to be multiplied, thereby creating an efficiency gain. This so-called “male multiplier effect” may be explained by a stronger psychological tendency in men to acquire resources.     

What is Trust? A Multidisciplinary Review,Critique, and Synthesis

Despite decades of interdisciplinary research on trust, the literature remains fragmented and balkanized with little consensus regarding its origins. This review documents how this came to be and attempts to offer a solution. Specifically, it evaluates issues of conceptualization found in the trust literature. I recommend that we move away from varieties of trust – multidimensional conceptualizations of trust – and toward a single trust concept built around four essential properties: actor A's beliefs, actor B's trustworthiness, the matter(s) at hand, and unknown outcomes. I finish the article by proposing a synthetic structural‐cognitive theoretical framework for investigating the causes and consequences of trust in everyday life.     

An instrumental perspective on apologizing in bargaining: The importance of forgiveness to apologize

Although very little research in bargaining has addressed how perpetrators should deal with the aftermath of unfair allocations, it has been proposed that an apology may help the reconciliation process. Prior research, however, only focused on whether apologies can reveal positive effects on the reconciliation process but did not focus yet on whether perpetrators are actually willing to apologize. In this paper we investigate perpetrator’s willingness to apologize for a trust violation in a bargaining setting. We hypothesized that perpetrators willingness to apologize would be a function of the extent to which the victim of the trust violation is willing to forgive. This effect, however, was expected to emerge only among those perpetrators who are low in dispositional trust. The results from a laboratory study with actual transgressions and actual apologetic behavior supported our predictions and thus emphasize an instrumental view on apologizing in bargaining situations.     

Urbanization-related distribution patterns and habitat-use by the marine mesopredator,giant Pacific octopus (<Emphasis Type="Italic">Enteroctopus dofleini</Emphasis>)

Urbanization is a process that heavily alters marine and terrestrial environments, though terrestrial urban ecosystems have been studied far more intensively. Terrestrial studies suggest that urbanization can facilitate mesopredators by enhancing food and shelter resources and reducing predation pressure from apex consumers. This in turn has considerable consequences for ecological communities. We evaluated spatial distribution patterns and habitat-use of the marine mesopredator, giant Pacific octopus (Enteroctopus dofleini), relative to terrestrial urbanization intensity in Puget Sound, Washington, USA. Using field surveys and citizen-contributed data for E. dofleini, we examined whether: (1) Distribution was related to urbanization, (2) Abundance was related to the extent of benthic anthropogenic debris, and (3) Diet differed as a function of urbanization and den cover. Our results suggest that urbanization impacts may differ with depth. Mixed-effects logistic regression model estimates for the probability of occurrence increased with urbanization in deep-water (> 24 m), and decreased with urbanization in shallow water (< 18 m). Accompanying field surveys indicated that E. dofleini abundance was correlated with the number of benthic anthropogenic debris items, and that E. dofleini diets were not affected by urbanization intensity or den cover. Though E. dofleini may be synanthropic within certain urban environments, the mechanisms driving this pattern likely differ from those affecting common urban mesopredators on land, with den provisioning from man-made structures being more important than altered food resources.     

I’m not like everybody else: urbanization factors shaping spatial distribution of native and invasive ants are species-specific

Urbanization is a major global change inducing complex and multiple modifications of landscapes and ecosystems. The spatial distributions of organisms experiencing these modifications will likely shift specifically, depending on each species’ response to each environmental modification induced by urbanization. We sampled two ant genera (Lasius and Tetramorium) at 1248 locations along an urbanization gradient in Lyon, France and used high resolution spatial layers for 18 spatial (e.g., open habitat fragmentation, bioclimatic data and surface temperatures) and temporal (e.g., comparison of Normalized Difference Vegetation Index between 1986 and 2015) environmental variables associated with urbanization. Coupling two different analytical methods (Outlying Mean Index and Boosted Regression Trees), we showed that each species’ distribution was influenced by its own combination of environmental factors. Two morphologically cryptic Tetramorium species (T. sp.E and T. sp.U2) were both highly abundant but with opposite responses to urbanization: while T. sp.E was favored by urbanized habitat, T. sp.U2 avoided urbanized areas. Among Lasius species, we detected 63 occurrences of the invasive ant Lasius neglectus, the distribution of which was favored only by embankments along roads. We found that, even at this reduced spatial scale, climatic effects influenced most species and interacted with urbanization factors.     

The structure of guanxi: Resolving problems of network assurance

Two widespread assumptions concerning networks, including guanxi networks, are that they function in terms of trust relations and that their structure is dyadic. This article subjects both assumptions to critical assessment and proposes alternative formulations. When the distinctions between trust and trustworthiness and between trust and assurance are made, then broader understandings of guanxi relationships emerge. The article shows that the assurance mechanism of guanxi is public exposure of transgressions against network norms, leading to the transgressor’s loss of face (mianzi). The necessity of third-party intervention of this type, typically but not exclusively through gossip, indicates the triadic rather than dyadic structure of guanxi relationships when sanction of reputation is included in the conceptualization of guanxi. Changes in guanxi during economic transition in China, from strong-to weaker-tie associations, require careful consideration of the changing nature of the mechanisms of face-loss.     

Marketization process predicts trust decline in China

Although previous literature has revealed the predictive effect of trust on economic development, whether the level of China’s market economy development predicts changes in trust across birth cohorts remains unknown. Study 1, a cross-temporal meta-analysis of 82 studies (N = 34,151), indicated that Chinese college students’ scores on the Interpersonal Trust Scale (ITS) decreased significantly from 1998 to 2011, and that the decline in interpersonal trust across birth cohorts was negatively associated with and predicated by the marketization index. Study 2 found that the levels of marketization of different provinces in China were negatively associated with the levels of trust in these provinces. The present research first proposed that the marketization process in China may predict or correlate with a trend of declining trust, and then demonstrated the validity of the proposal based on both longitudinal and cross-sectional evidence.     

More or less guanxi: Trust is 60% network context, 10% individual difference

The strong ties known in China as guanxi can be distinguished by a high level of trust relatively independent of the surrounding social structure. Using network data from a stratified probability sample of 700 entrepreneurs citing 4664 contacts, we study guanxi relative to other relations to learn how much individual differences such as well-being, business differences, political participation and demographic factors matter for the guanxi distinction. Two findings stand out: First, the connection between trust and social network is robust to most differences between individuals, especially business and political differences. Trust variance is 60% network context, and 10% individual differences. Trust increases within a relationship as network closure increases around the relationship, but some relationships mature into guanxi ties within which trust is high and relatively independent of the surrounding social structure. Second, when individual differences matter, they concern social isolation. Guanxi ties are more distinct in the networks around entrepreneurs with small, marginal families, and around those with small, closed networks. Both categories of entrepreneurs are likely to experience difficulties with respect to resource access and doing business with people beyond their network, which may explain why longstanding guanxi ties linked to important events are particularly distinct for these entrepreneurs.     

Adolescents gradually improve at detecting trustworthiness from the facial features of unknown adults

People can (to some extent) detect trustworthiness from the facial features of social partners, and populations which underperform at this task are at a greater risk of abuse. Here we focus on situations in which adolescents make a decision whether to trust an unknown adult. Adolescents aged 13–18 (N = 540) played a trust game, in which they made decisions whether to trust unknown adults based on their picture. We show that trusting decisions become increasingly accurate with age, from a small effect size at age 13 to an effect size 2.5 times larger at age 18. We consider the implications of this result for the development of prosociality and the possible mechanisms underlying the development of trustworthiness detection from faces.     

TRUST,TRUSTWORTHINESS, AND BUSINESS SUCCESS: LAB AND FIELD FINDINGS FROM ENTREPRENEURS

This article contributes to the literature on trust and small businesses in developing countries by linking the level of trust in others that entrepreneurs display in a lab setting to sales data outside of the lab. The results show a robust positive correlation between trust and business success (with sales used as a measure of success): The successful entrepreneurs invested in trust more than the less successful ones did. In the lab, trusting in others is highly profitable, with successful entrepreneurs doing so to the degree required to maximize revenue. However, I found no association between trustworthiness and business success. (JEL O17, L26, C91)     

Influence of urbanization on the occurrence and activity of aerial insectivorous bats

Activity and species-specific responses of insectivorous bats in different urban-forest conditions provides a general perspective on the adaptability and vulnerability of bat species towards urbanization intensity. Here we evaluated species richness and activity patterns of aerial insectivorous bats across an urbanized landscape in the highlands of Chiapas, in Mexico. Acoustic monitoring of echolocation calls was conducted for 27 nights over a period of four months. Species richness and relative activity of insectivorous bats were estimated in a landscape with different conditions of urbanization intensity: urban areas, non-urban and forest areas. We identified a total of 14 bat species and three phonotypes. Bat species richness and relative activity was similar (X² = 0.568, gl = 2, p > 0.05), but species composition differed among conditions. We observed a significant higher occurrence of Bauerus dubiaquercus, Eptesicus brasiliensis and Myotis californicus in forest sites. Urban sites presented higher occurrence of Molossus rufus and phonotype Molossidae 2, while non-urban sites presented a higher occurrence of Eptesicus furinalis and phonotype Molossidae 2. We were able to identify bat species according to their relative activity in relation todifferent landscape conditions. Species of the Molossidae family presented the highest activity in urban sites, which was positively affected by the number of streetlights, while species of the Vespertilionidae presented the highest activity in forest sites, which was positively related totree density. While urbanization tends to diminish native biodiversity and alter faunal communities, our results show a similar richness and relative activity of aerial insectivorous bats along the urban ecosystem. The effect of urbanization intensity becomes more apparent in species-specific bat activity; the response of species towards particular habitat conditions depends on local habitat quality and characteristics (i.e., presence of streetlights, vegetation cover and tree density).     

Relationship between land cover and insectivorous bat activity in an urban landscape

Despite the clear importance of conserving biodiversity in urbanized areas, research on how bats are influenced by urbanization has is only recently catching up to the more established body of research for urban birds. Much of the extant research has been limited to urban parks and other natural areas. Here I present the results of an acoustic survey of bats throughout the agricultural/forest/suburban/urban mosaic of the Minneapolis-St. Paul metropolitan area. Activity indices by each of the six recorded species (Eptesicus fuscus, Lasiurus cinereus, Lasiurus borealis, Lasionycteris noctivagans, Myotis sp., and Perimyotis subflavus) were used as response variables with land cover variables in a series of statistical models. Because bats may perceive the landscape at different scales, candidate models included land cover variables within 100, 500 and 1,000?m of the sampling location. Activity of L. noctivagans was negatively related to the amount of impervious surface and open habitat in the immediate landscape. L. borealis activity was positively correlated with immediate tree cover and with impervious surface at the 1,000?m scale. Tree cover and proximity to water were positively related to activity levels of Myotis sp., L. cinereus and P. subflavus, but only the latter was influenced by the amount of surrounding impervious surface. These results suggest that a one-size fits all approach to bat conservation in human modified landscapes is not appropriate, but also that certain species appear to do well in urban environments provided that there is sufficient tree cover.     

Plant-mycorrhizal fungi associations along an urbanization gradient: implications for tree seedling survival

Mycorrhizal fungi symbioses can be critical determining if established seedlings survive or not. Currently, in remnant forests, plants and their fungal symbionts are exposed to varied anthropomorphic effects related to urbanization, however, little is known about their impact on this association. We investigated the relationship between mycorrhizal fungi and tree seedling survival along an urbanization gradient. We planted three species of temperate tree seedlings (Acer rubrum, Carya ovata, and Quercus rubra) in three landscapes: urban, suburban, and rural. We measured the percent of root length colonized by mycorrhizal fungi and monitored survival during their first growing season. We analyzed mycorrhizal colonization as a function of landscape type (urban-rural) and additional variables known to contribute to mycorrhizal colonization (phosphorus, nitrogen, initial plant height). We then analyzed seedling survival as a function of the degree of mycorrhizal fungi colonization associated with the landscape gradient and of additional environmental factors (light and soil moisture). Within a species we found no changes in the levels of mycorrhizal fungi colonization across the urbanization gradient. Each species, however, had markedly different levels of colonization. Survival of A. rubrum was independent of mycorrhizal colonization, while C. ovata and Q. rubra had a significant positive response to increased mycorrhizal fungi. These findings highlight the resilience of mycorrhizal communities across the rural-urban gradient typical of this region, but they also underscore the potential sensitivity of some tree species to lower levels of mycorrhizal fungi colonization.     

Responding to a Health Crisis on Facebook: The Effects of Response Timing and Message Appeal

This study examined the effects of timing and message appeal of a crisis response on organizational perceptions and behavioral intentions on social media. Using a health crisis scenario, a 3 (one hour vs. one day vs. one week after the crisis) × 2 (emotional vs. rational appeal) between-subjects experiment (N = 502) found that a crisis response posted one day after the crisis on Facebook elicited greater trust towards the hospital in crisis compared to a response posted in one week. The one-hour response and one-day response did not show differential effects on trust towards the hospital. The effect of timing was mediated by perceived credibility of the crisis response. In addition, the emotional appeal triggered greater trust, perception of reputation, and intention to “like” the post; whereas the rational appeal elicited greater intention to share and comment on the post. The study provides both theoretical and practical implications.     

DO POSITIONAL CONCERNS DESTROY SOCIAL CAPITAL: EVIDENCE FROM 26 COUNTRIES

Research on the effects of positional concerns on individuals' attitudes and behavior is sorely lacking. To address this deficiency, we use the International Social Survey Programme 1998 data on 25,000 individuals from 26 countries to investigate the impact of relative income position on three facets of social capital: horizontal and vertical trust as well as norm compliance. Testing relative deprivation theory, we identify a deleterious positional income effect for persons below the reference income, particularly for their social trust and confidence in secular institutions. Also often a social capital‐lowering effect of relative income advantage occurs, while a rise in absolute income almost always contributes positively. These results indicate that a rise in income inequality in a society too large is rather detrimental to the formation of social capital. (JEL Z130, I300, D310)     

Does Activism in Social Science Explain Conservatives’ Distrust of Scientists?

Data from the General Social Survey suggest that conservatives have become less trustful of scientists since the 1970s. Gauchat argues that this is because conservatives increasingly see scientific findings as threatening to their worldview. However, the General Social Survey data concern trust in scientists, not in science. We suggest that conservatives’ diminishing trust in scientists reflects the fact that scientists in certain fields, particularly social science, have increasingly adopted a liberal-activist stance, seeking to influence public policy in a liberal direction.     

Social Capital and economic opportunities

Moving on from [Coleman, J.S., 1990. Foundations of Social Theory. Belknap Press of Harvard University Press, Cambridge, MA, London] and [Putnam, R.D., Leonardi, R., Nanetti, R.Y., 1993. Making Democracy Work Civic Traditions in Modern Italy. Princeton University Press, Princeton, NJ, Chichester], an ever-growing literature claims that repeating trustful interactions in the economy do sediment in higher levels of generalized trust. This aggregate stock of trust is then named Social Capital and treated as an input in the aggregate production function, such as labour, physical capital, or human capital. In this paper we argue that in many instances there is no need for meta-concepts like Social Capital, as trust is often simply the outcome of profit maximization. Whilst approaches that refer to Social Capital ignore the set of economic opportunities, incentives and conflicts behind trust, in this article we propose a simple model to show that when these are taken into account, the roles of trust and Social Capital can be better defined and understood.     

The two-ness of rural life and the ends of rural scholarship

I analyze the current return of academic rural doubt in the US in terms of an old intellectual quandary: what is the rural? I argue that scholars have two dominant epistemologies of the rural, what I term first rural and second rural, and correspondingly different political visions. By first rural I mean the material moment of the rural, to which we typically grant priority. By second rural I mean the ideal moment of the rural, which we typically regard as secondary, even when we argue that it is the only remaining rural. I analyze the origin of this priority of the rural in terms of the modernist/postmodernist divide, which I trace through the current American emphasis on first rural and the current European and Antipodean emphasis on second rural, noting how each emphasis often develops to the exclusion of the other. I trace as well the association of first rural with a modernist politics of defense of the rural boundary, and of second rural with a postmodernist politics of discourse that engages by deconstructing the rural. I argue for a rural plural vision that embraces first rural and second rural equally, stimulates a correspondingly more inclusive and practical politics of the rural, and keeps our understanding of the rural forever moving on.     

Virtuelle Arbeitsstrukturen durch Vertrauen,Zeitkompetenz und Prozessfeedback fördern

The article in the journal Gruppe. Interaktion. Organisation (GIO) deals with challenges of virtual structures of cooperation and of the team. It focuses especially on effects of personal characteristics, individual competence and team competence on team work and team performance in particular. Apparently, trust emerges in a different way in virtual working structures than in face-to-face teams. The discussion of the term ?trust‘ leads to a broader understanding of the development of trust and its importance, which helps to classify it in a process. Time competence is classified as particularly relevant to the emergence of trust, as teamwork becomes more flexible and team members take higher responsibilities than in face-to-face-teams. Control and responsibility move towards the members of the team, which in turn corresponds with a necessity for trust. Consequently, process feedback and transformational leadership can be identified as recommendable instruments for the enhancement of time competence and trust, which can lead to better team play. When taking a closer look at the role of leaders and team members in virtual environments, it becomes clear that reciprocity cannot be taken for granted in virtual teams. Differences in team structure as well as differing priorities in team goals throughout the team are similarly important as the frequency of contacts, the availability and reliability, or trustworthiness, of the individual team members.
