Are highly numerate individuals invulnerable to attribute framing bias? Comparing numerically and graphically represented attribute framing
Authors: Kreiner Hamutal , Gamliel Eyal 
Published: May 2017

AbstractJudgments and decisions are frequently biased by attribute framing, presenting either positive or negative attributes of an object. This paper focused on two factors previously shown to moderate the attribute‐framing bias: mode of presentation and participants' numeric ability. Whereas many studies demonstrated that graphical display reduced the bias, recent findings suggest that graphical manipulation can nevertheless elicit significant framing bias. Numeracy has been shown to moderate attribute‐framing bias when the quantitative information was represented by numbers. The present study examined to what extent numeracy would still moderate the framing bias when it is graphically elicited. The results showed a significant framing bias for graphically as well as for numerically represented framing scenarios. Critically, whereas numeracy moderated the framing bias in numerically represented scenarios, it did not have a similar moderating effect when the quantitative information in the scenario was graphically represented. Theoretical and practical implications of the findings are discussed.
The power of politics: How political leaders in Serbia discursively manage identity continuity and political change to shape the future of the nation
Authors: Obradović Sandra , Howarth Caroline 
Published: May 2017

AbstractThe construction of national identities through political discourse is a growing field of interest to social psychologists, particularly as many countries face changing demographics, borders and social realities as part of globalization, immigration and continued political integration and conflict. Through an analysis of 17 key speeches by Serbian politicians over the past 25 years, the present paper explores the question of how politicians, as entrepreneurs of identity, discursively manage the relationship between identity continuity and political change over time, in attempts to construct the future of a nation. We particularly explore this issue in the context of Serbia's present political aspirations toward joining the European Union. The findings indicate that (i) political change becomes negotiated within the framework of established and legitimized identity discourses that have developed over time, and (ii) while history is frequently drawn on to support political agendas, it is successful to the extent that this history offers a sense of cultural continuity rather than a coherent narrative of historical events and time periods. We conclude by arguing for the benefits that a diachronic approach to political discourse can offer social psychologists interested in the discursive construction of national identity.
It is written all over your face: Socially rejected people display microexpressions that are detectable after training in the Micro Expression Training Tool (METT)

AbstractSocial rejection is a powerful negative emotional experience, yet rejected people often appear stoic and unmoved. That is, their macroexpressions of emotion are not accurate reflections of their emotional states. Yet, there is reason to believe that rejected people exhibit involuntary microexpressions of negative emotion. We contrasted people's macroexpressions of emotion with their microexpressions subsequent to an acceptance or rejection experience. Observers coded microexpressions after being trained with the Micro Expression Training Tool. Rejected participants expressed more sad and angry microexpressions than did accepted participants. This research demonstrates that socially rejected people display negative microexpressions that are detectable by observers trained in the Micro Expression Training Tool.
Congruity of observed social support behaviors and couple relationship quality
Authors: Chow Chong Man , Ruhl Holly 
Published: May 2017

AbstractThis study examined the role of congruity in couples' social support behaviors on relational outcomes. Participants (N = 123 couples, Mage = 26.91, SD = 8.46) completed surveys on relationship satisfaction and discord. Positive and negative behaviors were then observed during supportive interactions. Results revealed that the detrimental effect of negative behaviors on satisfaction was buffered by a partner's engagement in fewer negative behaviors or intensified by more negative behaviors. Further, the beneficial effect of positive behaviors on reducing discord was amplified by a partner's engagement in more positive behaviors or offset by fewer positive behaviors. Last, the detrimental effect of negative behaviors on discord was buffered by a partner's engagement in more positive behaviors. These findings highlight the complex nature of dyadic relationships and provide insights for developing interventions focused on improving romantic relationship quality.
Is regulatory focus related to minimal and maximal standards? Depends on how you ask!
Authors: Lalot Fanny , Quiamzade Alain , Falomir‐Pichastor Juan Manuel 
Published: May 2017

AbstractRegulatory focus theory suggests that hopes and aspirations (promotion focus) function like maximal goals, whereas duties and responsibilities (prevention focus) function like minimal goals. However, past research has not always reliably found such a link between regulatory focus and maximal–minimal goals or standards. In the present research, we hypothesised that this inconsistency can be explained, at least in part, by conceptual differences resulting in the use of different, specific wording. In four studies, we compared wording in terms of the relative magnitude of the goals to wording in terms of their absolute versus gradual perception. Results showed that regulatory focus (manipulated or measured) consistently relates to maximal versus minimal standards framed as goals of different magnitudes, but not to the goals framed according to an absolute–gradual perception. Implication of the results for regulatory focus research is discussed.
Superheroes for change: Physical safety promotes socially (but not economically) progressive attitudes among conservatives
Authors: Napier Jaime L. , Huang Julie , Vonasch Andrew J. , Bargh John A. 
Published: May 2017

AbstractAcross two studies, we find evidence for our prediction that experimentally increasing feelings of physical safety increases conservatives' socially progressive attitudes. Specifically, Republican and conservative participants who imagined being endowed with a superpower that made them invulnerable to physical harm (vs. the ability to fly) were more socially (but not economically) liberal (Study 1) and less resistant to social change (Study 2). Results suggest that socially (but not economically) conservative attitudes are driven, at least in part, by needs for safety and security.
I feel you feel what I feel: Perceived perspective‐taking promotes victims' conciliatory attitudes because of inferred emotions in the offender
Authors: Berndsen Mariëtte , Wenzel Michael , Thomas Emma F. , Noske Breeanna 
Published: May 2017

AbstractIn the context of bullying in a nursing workplace, we test the argument that an offender's perspective‐taking promotes victim conciliation, mediated by perceived perspective‐taking, that is, the extent to which the victim perceives the offender as taking their perspective. Perceived perspective‐taking facilitates the attribution of moral emotions (remorse, etc.) to the offender, thereby promoting conciliatory victim responses. However, perceived perspective‐taking would be qualified by the extent to which the severity of consequences expressed in the offender's perspective‐taking matches or surpasses the severity for the victim. In Studies 1 and 2 (Ns = 141 and 122, respectively), victims indicated greater trust and/or forgiveness when the offender had taken the victim's perspective. This was sequentially mediated by perceived perspective‐taking and victim's inference that the offender had felt moral emotions. As predicted, in Study 2 (but not Study 1), severity of consequences qualified victims' perceived perspective‐taking. Study 3 (N = 138) examined three potential mechanisms for the moderation by severity. Victims attributed greater perspective‐taking to the offender when the consequences were less severe than voiced by the offender, suggesting victims' appreciation of the offender's generous appraisal. Attributions of perspective‐taking and of moral emotions to the offender may play an important role in reconciliation processes.Key outcome: To the extent that victims perceive the offender as taking their perspective (perceived perspective‐taking), they infer that the offender feels more moral emotions, prompting victims to be more conciliatory. Perceived perspective‐taking benefits from the offender over‐stating the consequences to the victim.
Molecularly imprinted solid‐phase extraction coupled with LC–APCI–MS–MS for the selective determination of serum cholesterol

Published: May 2017

AbstractThe assessment of selective molecularly imprinted solid‐phase extraction (MISPE) for clean‐up and extraction of cholesterol (CHO) from bovine and human serum samples was evaluated. Two molecular imprinted polymers (MIP) based on organic and inorganic/organic (hybrid) materials were obtained and compared regarding recovery and selectivity toward CHO. Optimum chromatographic separation between the CHO and its isobaric compound lathosterol (LATHO) has been achieved within 15 min using an Agilent Poroshell 120 EC‐C18 column (120 mm × 3.0 mm, 2.7 μM) and mobile phase consisting of acetonitrile:methanol (8:2, v/v) at a flow rate of 0.6 mL min−1. Mass spectrometry detection was operated in atmospheric pressure chemical ionization (APCI) (+) mode and the SIM transitions [M – H2O + H]+ for CHO and LATHO were 364.1 → 161.2 → 95.2 and 364.1 → 95.1 → 81.1 m/z, respectively. The sample preparation could be accomplished within 1 h, and the matrix effect on the MS signal after sample pretreatment did not interfere in the analyses. The method provided a good linear range (0.013–312 μM.) with coefficients of determination of R2 > 0.99, substantial sensitivity (limits of detection of 6.5 nM), good recovery (∼90%), high reproducibility (intraday and interday relative standard deviations less than 15%) and satisfactory accuracy (relative error ranged from –13.46% to 11.54%). The organic MIP showed superior performance compared with the hybrid. Finally, the MISPE procedure followed by LC–APCI–MS–MS analysis showed their suitable applicability to examine CHO and LATHO in serum samples.

Published: May 2017

AbstractThis work outlines a novel parameter that is capable of characterizing the flatness of the normalized signal‐to‐noise ratio for resource allocation purposes in power line communication (PLC) systems, which are based on multicarrier modulation schemes. This parameter, named normalized signal‐to‐noise ratio coherence bandwidth, can be used for grouping adjacent subchannels therefore reducing the computational complexity of resource allocation techniques. Additionally, we discuss a comparative analysis between the proposed parameter and the coherence bandwidth for resource allocation purposes, which leads us to conclude that the former is more appropriate than the latter for PLC systems. Moreover, we show a statistical analysis of the proposed parameter and model it with different distributions based on noise measurements and channel estimates of broadband in‐home, outdoor, and hybrid PLC‐wireless environments. On the basis of data sets obtained from measurement campaigns covering the frequency bands of 1.7 to 30, 1.7 to 50, and 1.7 to 100 MHz, we show that the best distributions for modeling the proposed parameter are inverse Gaussian, Nakagami, gamma, and Gaussian mixture, depending on the type of the channel (in home, outdoor, and hybrid PLC wireless) and the frequency band.
Cryptanalysis and improvement of a biometric‐based remote user authentication protocol usable in a multiserver environment
Authors: Chandrakar Preeti , Om Hari 
Published: May 2017

AbstractRecently, Amin and Biswas have discussed a bilinear pairing–based three‐factor remote user authentication protocol, claiming it to be secured against various attacks. We scrutinize this protocol and find that it is vulnerable to identity guessing attack, password guessing attack, user untraceability attack, user‐server impersonation attack, new smart card issue attack, and privileged insider attack. In this paper, we propose an elliptic curve cryptography and biometric‐based remote user authentication protocol for a multiserver environment by overcoming these drawbacks. We conduct its informal and formal security analysis to show that it resists all known security attacks. The Burrows‐Abadi‐Needham (BAN) logic verifies that our protocol facilitates mutual authentication and session key agreement securely. We simulate it using the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool to certify that it can be protected from passive and active threats, including replay and man‐in‐the‐middle attacks. Furthermore, the proposed protocol provides more security attributes and better complexity in terms of smart card storage cost, computation cost, estimated time, and communication cost, as compared with the related existing protocols.
Revealing the inner secrets of intumescence: Advanced standard time temperature oven (STT Mufu+)—μ‐computed tomography approach
Authors: Morys Michael , Illerhaus Bernhard , Sturm Heinz , Schartel Bernhard 
Published: May 2017

SummaryIntumescent coatings have been used for fire protection of steel for decades, but there is still a need for improvement and adaptation. The key parameters of such coatings in a fire scenario are thermal insulation, foaming dynamics, and cohesion. The fire resistance tests, large furnaces applying the standard time temperature (STT) curve, demand coated full‐scale components or intermediate‐scale specimen. The STT Mufu+ (standard time temperature muffle furnace+) approach is presented. It is a recently developed bench‐scale testing method to analyze the performance of intumescent coatings. The STT Mufu+ provides vertical testing of specimens with reduced specimen size according to the STT curve. During the experiment, the foaming process is observed with a high‐temperature endoscope. Characteristics of this technique like reproducibility and resolution are presented and discussed. The STT Mufu+ test is highly efficient in comparison to common tests because of the reduced sample size. Its potential is extended to a superior research tool by combining it with advanced residue analysis (μ‐computed tomography and scanning electron microscopy) and mechanical testing. The benefits of this combination are demonstrated by a case study on 4 intumescent coatings. The evaluation of all collected data is used to create performance‐based rankings of the tested coatings.

AbstractRecurrent H3F3A and IDH2 mutations have been reported in giant cell tumor of bone (GCTB). However, the reported incidences have varied, and other molecular genetic alterations have not been identified due to the small number of cases analyzed with comprehensive methods. Moreover, the relative sensitivities of Sanger sequencing and next‐generation sequencing (NGS) for the detection of H3F3A mutations in DNA extracted from archival formalin‐fixed paraffin‐embedded (FFPE) samples for clinical diagnosis have not been assessed. To address these issues, we conducted whole‐exome sequencing of 7 GCTBs and integrated the previously published genomic sequencing data of 6 GCTBs. We subsequently performed targeted sequencing of an additional 39 GCTBs, including 2 atypical cases and an extremely rare case of primary malignant transformation of GCTB. We also evaluated the sensitivity of Sanger sequencing for detecting H3F3A mutations in FFPE samples that are usually used for clinical diagnosis. H3F3A glycine hotspot mutations were the most frequently detected mutations (96%) in the 52 GCTBs by NGS. Of the 50 hotspot mutations, p.G34W was observed in 48 cases and p.G34L/G34R was detected in one. One of two atypical GCTB cases with wild‐type H3F3A had a H3F3B mutation (p.G34V). Other mutated genes were not recurrent. Sanger sequencing did not detect H3F3A mutations in 10 of 15 H3F3A NGS mutation‐positive FFPE samples. In conclusion, we confirmed that H3F3A is the most frequently mutated GCTB driver gene, and that H3F3A mutations are not present in atypical GCTBs. Sanger sequencing was much less sensitive than targeted NGS for detecting H3F3A mutations in FFPE samples.
Development and evaluation of the coaxial cable casing imager: a cost‐effective solution to real‐time downhole monitoring for CO2 sequestration wellbore integrity

Published: May 2017

AbstractCO2 leakage is a major concern in a geological carbon sequestration projects due to adverse environmental consequences, where the main leakage risk is identified to be along existing wells through a thick, low‐permeable cap rock. To pursue robust and cost effective real‐time downhole monitoring technology for CO2 sequestration wellbore integrity, a permanently deployed coaxial cable casing imager is developed and evaluated in laboratory in this paper. The prototype of the casing imager consists of evenly distributed coaxial cable strain sensors helically wrapped around the pipe. The system is deployed on both PVC pipe and steel pipe to test its performance in casing deformation monitoring, including axial compression, radial expansion, bending, and ovalization. The strain sensors are pre‐stressed and then helically wrapped onto the pipe with high strength epoxy. Multiple linear variable differential transformers (LVDTs) or strain gauges are used as an independent measurement of the actual pipe deformation in comparison to the casing imager measured pipe deformation. The test results demonstrated the ability of the lab‐scale casing imager prototype in real‐time casing deformation monitoring, including axial compression, radial expansion, bending, and ovalization, which would prove of great value in evaluating wellbore integrity state and providing early warnings of leakage risk that will contaminate the groundwater during CO2 injection. The low cost and high robustness of the distributed coaxial cable sensors will greatly lower the downhole monitoring cost and increase the system longevity. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd.
Ordinal response generalized difference in differences with varying categories: The health effect of a disability program in Korea
Authors: Kim Young‐sook , Lee Myoung‐jae 
Published: May 2017

AbstractWe consider the use of difference in differences (DD) to evaluate the effect of an activity assistance program on the health of severely disabled Koreans. There are, however, 2 problems in the data: the number of response categories for self‐assessed health changed over the waves of the repeated cross‐section survey and the “parallel untreated response path” assumption for DD is suspect. We show how to overcome these problems by renormalizing parameters and applying “generalized difference in differences (GDD).” We find a significantly positive effect of the program with DD, but not with GDD. Our solutions should prove useful in applications in which one or other of these problems arise.

Published: May 2017

AbstractObjectiveKratom (Mitragyna speciosa. Korth) is an indigenous medicinal plant of Southeast Asia. This review paper aims to describe the trends of kratom use in Southeast Asia.DesignA literature review search was conducted through ScienceDirect, Scopus, ProMed and Google Scholar. Twenty‐five articles illustrating kratom use in humans in Southeast Asia were reviewed.ResultsKratom has long been used by rural populations in Southeast Asia as a remedy for common ailments, to fight fatigue from hard manual work, as a drink during social interaction among men, and in village religious functions. Studies based on self‐reports suggest that prolonged kratom use does not result in serious health risks or impair social functioning. Two recent trends have also emerged: (a) Kratom is reportedly being used to ease withdrawal from opioid dependence in rural settings; whereas (b) in urban areas, adulterated kratom cocktails are being consumed by younger people to induce euphoria.ConclusionsLegal sanctions appear to have preceded serious scientific investigations into the claimed benefits of ketum. More objective‐controlled trials and experiments on humans need to be conducted to validate self‐report claims by kratom users in the community.
An empirical investigation of analytical procedures using mixture distributions
Authors: Christopher Westland J. 
Published: May 2017

SummaryAnalytical procedures are evaluations of account and transaction flow information made by a study of plausible relationships between both accounting and non‐accounting data. This study investigates the performance of Tweedie distributions (which have Gaussian distributions as members) in improving fit of zero‐inflated, non‐negative, kurtotic and multimodal analytical review data. The study found that account valuations are more informative than marginal data in analytical review, that mixture Poisson–Gamma distributions offer better fit than Gaussian distributions, even under assumptions of central limit theorem convergence, and that mixture Poisson–Gamma distributions provide better predictions of future account and transaction volumes and values. Model performance improvement with price versus returns data in this empirical study was substantial: from less than one‐quarter of variance, to almost two‐thirds. Tweedie generalized linear model risk assessments were found to be a magnitude smaller than traditional risk assessments, lending support to market inefficiency and increased risk from idiosyncratic factors. An example with several differing distributions shows that use of mixture distributions instead of point estimation can reduce sample size while retaining the power of the audit tests. The results of this study are increasingly important as accounting datasets are growing exponentially larger over time, requiring well‐defined roles for models, algorithms, data and narrative which can only be achieved with statistical protocols and algorithmic languages.
