Personality Psychology and Economics

This paper explores the power of personality traits both as predictors and as causes of academic and economic success, health, and criminal activity. Measured personality is interpreted as a construct derived from an economic model of preferences, constraints, and information. Evidence is reviewed about the "situational specificity" of personality traits and preferences. An extreme version of the situationist view claims that there are no stable personality traits or preference parameters that persons carry across different situations. Those who hold this view claim that personality psychology has little relevance for economics. The biological and evolutionary origins of personality traits are explored. Personality measurement systems and relationships among the measures used by psychologists are examined. The predictive power of personality measures is compared with the predictive power of measures of cognition captured by IQ and achievement tests. For many outcomes, personality measures are just as predictive as cognitive measures, even after controlling for family background and cognition. Moreover, standard measures of cognition are heavily influenced by personality traits and incentives. Measured personality traits are positively correlated over the life cycle. However, they are not fixed and can be altered by experience and investment. Intervention studies, along with studies in biology and neuroscience, establish a causal basis for the observed effect of personality traits on economic and social outcomes. Personality traits are more malleable over the life cycle compared to cognition, which becomes highly rank stable around age 10. Interventions that change personality are promising avenues for addressing poverty and disadvantage.
The Effect of Word- and Comprehension-Emphasis Instruction on Reading Performance

Three instructional procedures were compared to assess their effects on reading comprehension and word recognition. One approach emphasized comprehension, i.e., students were regularly questioned about the reading content and were not corrected when they made oral reading errors. A second approach consisted of word emphasis, whereby subjects were corrected for all reading errors and received error-word drills each day. They were not questioned about the content of their reading selection. The third approach combined aspects of the other two, including error-word corrections and drill along with comprehension questions. No differences were found among treatment effects on comprehension and oral reading; however, on an isolated word-recognition measure the approaches which included error-word drill produced higher scores.
Forewarning and Forearming Stereotype-Threatened Students

This study investigated communicative strategies for helping female students cope with “stereotype threat”. Participants completed a difficult math test after reading one of three coping messages: a control message encouraging perseverance, a “suppression” message describing stereotype threat and instructing participants to suppress associated thoughts, and a “replacement” message describing the phenomenon and presenting an alternative, self-relevant positive stereotype. As predicted, a performance gap favoring males was observed in the control condition. This gap widened when students attempted to suppress threatening thoughts but narrowed when they were primed with the alternative positive stereotype. Our results demonstrate that priming a positive achieved identity (e.g., private college student) can subdue stereotype threat associated with an ascribed identity (e.g., female).
Noise Normalizes Firing Output of Mouse Lateral Geniculate Nucleus Neurons

The output of individual neurons is dependent on both synaptic and intrinsic membrane properties. While it is clear that the response of an individual neuron can be facilitated or inhibited based on the summation of its constituent synaptic inputs, it is not clear whether subthreshold activity, (e.g. synaptic “noise”- fluctuations that do not change the mean membrane potential) also serve a function in the control of neuronal output. Here we studied this by making whole-cell patch-clamp recordings from 29 mouse thalamocortical relay (TC) neurons. For each neuron we measured neuronal gain in response to either injection of current noise, or activation of the metabotropic glutamate receptor-mediated cortical feedback network (synaptic noise). As expected, injection of current noise via the recording pipette induces shifts in neuronal gain that are dependent on the amplitude of current noise, such that larger shifts in gain are observed in response to larger amplitude noise injections. Importantly we show that shifts in neuronal gain are also dependent on the intrinsic sensitivity of the neuron tested, such that the gain of intrinsically sensitive neurons is attenuated divisively in response to current noise, while the gain of insensitive neurons is facilitated multiplicatively by injection of current noise- effectively normalizing the output of the dLGN as a whole. In contrast, when the cortical feedback network was activated, only multiplicative gain changes were observed. These network activation-dependent changes were associated with reductions in the slow afterhyperpolarization (sAHP), and were mediated at least in part, by T-type calcium channels. Together, this suggests that TC neurons have the machinery necessary to compute multiple output solutions to a given set of stimuli depending on the current level of network stimulation.
The Healing of Nations: The Promise and Limits of Political Forgiveness and International Governance of War-Torn Territories: Rule and Reconstruction

The Healing of Nations: The Promise and Limits of Political Forgiveness. By Mark R. Amstutz. Lanham, MD: Rowman and Littlefield, 2005, 296p. $79.00 cloth, $29.95 paper. International Governance of War-Torn Territories: Rule and Reconstruction. By Richard Caplan. Oxford: Oxford University Press, 2005, 304p. $99.00 cloth. In the late 1990s, the World Bank conducted a far-reaching research program on the causes of civil war. Were civil wars inspired mainly by genuine unresolved political grievances, or were they precipitated by predatory groups (including governments) seeking to profit monetarily from violence and instability? Among the bank's myriad findings, many of them hotly disputed, came one assertion around which there was almost universal consensus: that the single factor that made future conflict likely was past conflict concluded within the previous five years. This finding, based on exhaustive empirical research, has two profound consequences for thinkers and practitioners engaged in formulating and assessing the transition from war to peace. On the one hand, it shows that the risks and costs of failure are high. Failure to foster political reconciliation, to tackle the root causes of conflict, to rebuild shattered economies and (among other things) provide a secure environment is more likely to lead to the outbreak of war and oppression than any other factor. On the other hand, the World Bank findings show that—contra some skeptics who argue that third parties have no part to play and that political conflicts are best resolved violently—long-term success need not be a chimera: Build peace effectively for over five years and the chances of future conflict decrease dramatically. There are clear lessons for Iraq here—civil war need not be inevitable, but to avoid it requires getting a wide variety of things right that are currently going wrong.
Association between Variants of the Leptin Receptor Gene (LEPR) and Overweight: A Systematic Review and an Analysis of the CoLaus Study

Background Three non-synonymous single nucleotide polymorphisms (Q223R, K109R and K656N) of the leptin receptor gene (LEPR) have been tested for association with obesity-related outcomes in multiple studies, showing inconclusive results. We performed a systematic review and meta-analysis on the association of the three LEPR variants with BMI. In addition, we analysed 15 SNPs within the LEPR gene in the CoLaus study, assessing the interaction of the variants with sex. Methodology/Principal Findings We searched electronic databases, including population-based studies that investigated the association between LEPR variants Q223R, K109R and K656N and obesity- related phenotypes in healthy, unrelated subjects. We furthermore performed meta-analyses of the genotype and allele frequencies in case-control studies. Results were stratified by SNP and by potential effect modifiers. CoLaus data were analysed by logistic and linear regressions and tested for interaction with sex. The meta-analysis of published data did not show an overall association between any of the tested LEPR variants and overweight. However, the choice of a BMI cut-off value to distinguish cases from controls was crucial to explain heterogeneity in Q223R. Differences in allele frequencies across ethnic groups are compatible with natural selection of derived alleles in Q223R and K109R and of the ancient allele in K656N in Asians. In CoLaus, the rs10128072, rs3790438 and rs3790437 variants showed interaction with sex for their association with overweight, waist circumference and fat mass in linear regressions. Conclusions Our systematic review and analysis of primary data from the CoLaus study did not show an overall association between LEPR SNPs and overweight. Most studies were underpowered to detect small effect sizes. A potential effect modification by sex, population stratification, as well as the role of natural selection should be addressed in future genetic association studies.
A 3-year follow-up study of overdentures retained by mini-dental implants.

PURPOSE This study evaluated overdentures retained by mini-dental implants (MDIs) as a treatment option for complete edentulism during a 3-year follow-up period. MATERIALS AND METHODS This observational clinical study included completely edentulous patients who were treated with MDI-retained overdentures. The MDIs were supplied by the manufacturer. RESULTS Twenty-three patients received 7 maxillary and 16 mandibular MDI overdentures retained by 110 MDIs. Of the 36 MDIs placed in the maxilla, 8 failed (in two patients), 2 had compromised survival, 3 displayed satisfactory survival, and 23 were successful. Of the 74 MDIs placed in the mandible, 11 displayed satisfactory survival and 63 were successful. The marginal bone loss was more pronounced for the MDIs placed mesially (intercalated), in areas of decreased ridge width and bone density, and with lower values of insertion torque. The overdentures fractured in seven patients; in 4 of them, this corresponded to the implant housing area. Self-reported reasons for patient dissatisfaction included occasional pain under the overdenture (n = 5) and instability of the maxillary antagonist complete denture (n = 4). CONCLUSION Based on this research, considering its limitations, it is possible to conclude that survival rates and health status are better for MDI overdentures applied in the mandible than for those applied in the maxilla. The most severe prosthetic complications encountered were overdenture base fracture, matrix detachment, and instability of the maxillary antagonist denture.
Regularizing Deep Neural Networks by Noise: Its Interpretation and Optimization

Overfitting is one of the most critical challenges in deep neural networks, and there are various types of regularization methods to improve generalization performance. Injecting noises to hidden units during training, e.g., dropout, is known as a successful regularizer, but it is still not clear enough why such training techniques work well in practice and how we can maximize their benefit in the presence of two conflicting objectives---optimizing to true data distribution and preventing overfitting by regularization. This paper addresses the above issues by 1) interpreting that the conventional training methods with regularization by noise injection optimize the lower bound of the true objective and 2) proposing a technique to achieve a tighter lower bound using multiple noise samples per training example in a stochastic gradient descent iteration. We demonstrate the effectiveness of our idea in several computer vision applications.
Beyond Hierarchies and Networks: Institutional Logics and Change in Transboundary Spaces

In almost all subfields of political science in the last third of the twentieth century, it was claimed that we are witnessing a transformation of political order from hierarchies to networks. This paper traces institutional change during the twentieth century by examining structures and modes of interaction in transboundary regions in Europe and North America. First, it challenges functionalist explanations of institution-building and institutional change. Instead, the impact of general discourses and ideas is highlighted. Second, it takes a closer look at the hierarchies-to-networks transformation thesis. Whereas this thesis can be confirmed if we define hierarchies and networks as patterns of interaction, if we define hierarchies and networks in terms of modes of interaction this is less certain. De jure, institutional elements implying a “hierarchical order” have been supplanted in newer institutions by provisions allowing for “majority voting. ” De facto, nothing has changed, since these modes of interaction have never actually been used. In practice, the only way to achieve joint action has always been and still is through “agreement” or “consent. ” What has changed over the years, though, is the institutionalized approach to reaching “agreement. ” The older approach uses a technocratic-deductive logic. In recent years, we have been able to observe various new approaches in cross-border regions: a symbolic-inductive logic in Western Europe, a utilitarian-evolutionary logic along the U.S.-Mexican border, and a normative-constructivist logic along the U.S.-Canadian border. Based on the empirical findings, I conclude that institutional theory should pay more attention to the fact that many political institutions provide orientation, shape identities, and mobilize activities through emotional symbols.
Incidence and Clinical Significance of Aberrant T-Cell Marker Expression on Diffuse Large B-Cell Lymphoma Cells

Introduction: Aberrant expression of T-cell markers is occasionally observed in B-cell lymphomas. We conducted a retrospective study to establish its incidence and to determine its relationship with clinical features of patients with diffuse large B-cell lymphoma (DLBCL). Patients and Methods: We reviewed DLBCL patients diagnosed between January 2002 and April 2009. Patients fulfilled the following criteria: (1) age >18 years, (2) HIV negative, (3) B-cell lymphoma confirmed by restricted expression of surface immunoglobulin light chains by flow cytometry (FCM). Aberrant T-cell marker expression (ATCME) was defined as positivity for CD2, CD3, CD4, CD7, and/or CD8 on DLBCL cells by FCM. Phenotyping was also performed by immunohistochemistry (IHC). Patients were grouped according to positive or negative ATCME and their clinical features including survival were compared. Results: Of 150 patients, 11 (7.3%) showed ATCME; CD2 and CD7 were most often expressed. ATCME was less often detected and the signal was weaker using IHC. There were no statistically significant differences in clinical features between the two groups. Conclusions: FCM may be useful to detect ATCME in a small amount of lymphoma cells. The mechanism responsible for ATCME, and whether it contributes in any way to the pathogenesis of B-cell neoplastic transformation, requires clarification.
To Travel or to Compete: Motivations of Masters Swimmers

The underlying motivations behind participating in a sports event such as a swim meet are complex and varied especially for adult participants. These motivations may be related to the thrill of competition or excitement at traveling to a new pool or aquatic facility. Investigations of motivations behind participation can enable meet directors and aquatic facility managers to create more memorable experiences that boost participation and encourage repeat visitors who produce social and economic benefits for the aquatic facility and event. We measured motivations of Masters swimmers using the Participant Motivation Questionnaire (PMQ) modified for swimmers and the Travel Career Ladder (TCL) at the 2006 US Masters Swimming Short Course Championships. Descriptive and multivariate statistics revealed that Masters swimmers participated primarily for competitive reasons with travel only as a secondary motivator. Participating to be with other members of their team was revealed as another important motivation. Understanding the motivations behind swim participants is a complex phenomenon. They are influenced by a host of behavioral factors that are different for each person and may shift across the lifespan (Hastings, Kurth, Schloder, & Cyr, 1995; Vallerand & Losier, 1999). Therefore, what may make one person choose to attend a special event at an aquatic facility such as a swim meet may not be the same for another person. One way for aquatic facilities to be financially solvent and to achieve prestige includes the hosting of high level swimming competitions or other related events. An understanding of how to attract and keep swimmers coming back is essential for the ongoing vitality of an aquatic facility and for annual events. For the home team there also are motivations to host these events based on perceptions such as home pool advantage, ease of access, and overall savings in cost and expenditure of resources. Hosting a sporting event is viewed as a vehicle for economic and community development (Gibson, 1998). Past research examining the economic impacts of specific sport tourism events from the host community perspective found that residents view the event favorably and was more likely to volunteer their time to the event (Soutar & McLeod, 1993; Walo, Bull, & Breen, 1996). In addition to the above mentioned socioeconomic benefits of hosting a sporting event, the event
Inducing Cooperative Behavior among Proselfs versus Prosocials: The Moderating Role of Incentives and Trust

This study investigates how an individual’s social value orientation (SVO) interacts with explicit cooperative incentives on one hand, and intrinsic and extraneously induced trust on the other hand, to affect cooperative behavior. In three experiments, subjects (n = 322) played a one-shot prisoner’s dilemma (PD; with weak cooperative incentives) and an assurance game (AG; with strong cooperative incentives) in conditions with or without trust signals. The authors found, as expected, that cooperative behavior is strongly spurred by explicit incentives, but not by trust, among people with a proself value orientation. Conversely, trust is very important to enhance cooperative behavior of participants with a prosocial value orientation, whereas explicit incentives are less important compared to proselfs. The authors conclude that this study reveals two fundamentally different logics of cooperative behavior: one based on extrinsic incentives and the other on trust.
Exploring the Actual and Potential Rhetoric-reality Gaps in Environmental Education and their Implications for Pre-service Teacher Training

The mismatch between the advocated views of theorists and the teaching realities in school environmental education is widely recognised. There is relatively little research examining the advocated practices of teachers themselves, other than already environmentally active teachers, to indicate the nature of the 'potential' rhetoric-reality gap that might exist if all constraints were removed, and teachers had a completely free choice in designing their own environmental education programmes. This article identifies such gaps by exploring current practices and teachers' views on selected components of environmental education, across a complete teacher training partnership. This information has been used to help prioritise the content and approaches used by pre-service teachers when conducting school-based environmental activities. The investigation reveals that although most schools lack a written policy on environmental education, most have a positive attitude towards the large majority of selected components and these are usually addressed in school. Teachers are not generally compelled to deliver aspects of environmental education that they deem inappropriate. Of the 10 components not currently addressed by most of these schools, the findings suggest that five would be added if constraining factors were removed, but a further five would remain absent. The overall potential rhetoric-reality differences in this case study are thus smaller than the actual existing differences, but still fall short of some theorists' goals. Within the pre-service training programme, efforts have been concentrated on components that are: (i) currently practised in most schools; and (ii) receive a positive response from most teachers, and this has resulted in markedly improved feedback from schools and trainees alike.
Attention and Executive Disorders in Neurofibromatosis 1: Comparison Between NF1 With ADHD Symptomatology (NF1 + ADHD) and ADHD Per Se

Objective: To compare children with Neurofibromatosis type 1 and associated ADHD symptomatology (NF1 + ADHD) with children having received a diagnosis of ADHD without NF1. The idea was that performance differences in tasks of attention between these two groups would be attributable not to the ADHD symptomatology, but to NF1 alone. Method: One group of children with NF1 + ADHD (N = 32), one group of children with ADHD (N = 31), and one group of healthy controls (N = 40) participated in a set of computerized tasks assessing intensive, selective, and executive aspects of attention. Results: Differences were found between the two groups of patients in respect of several aspects of attention. Children with NF1 + ADHD did not always perform worse than children with ADHD. Several double dissociations can be established between the two groups of patients. Conclusion: ADHD symptomatology in NF1 does not contribute to all attention deficits, and ADHD cannot account for all attention impairments in NF1.
Heightened Maternal Separation Anxiety in the Postpartum

Maternal separation anxiety (MSA) refers to feelings of anxiety elicited in a mother during separation from her infant. The role of social and structural disadvantage in the etiology of high MSA has been overlooked. Secondary analysis of data from the Longitudinal Study of Australian Children (N = 3,897) revealed that compared to socioeconomically advantaged women, women of low socioeconomic position had a fourfold increased odds of reporting high (>80th percentile) MSA (odds ratio = 4.37, 95% confidence interval = 3.24-5.89), even when maternal and infant characteristics were controlled for. Inadequate social support and residing in a poor quality neighborhood were also significantly associated with high MSA in adjusted analyses. These findings indicate that high MSA is more common in socioeconomically disadvantaged women and might be a response to adverse circumstances. Mothers’ experience of, and reasons for, MSA needs to be considered in policy formulation about parental leave and postpartum employment, particularly for disadvantaged mothers.
