Competitive equilibrium with intuitionistic agents

This paper studies an economy whose agents perceive their consumption possibilities subjectively, and whose preferences are defined on what they subjectively experience, rather than on those alternatives that are objectively present. The model of agents’ perceptions is based on intuitionistic logic. Roughly, this means that agents reason constructively: a solution to a problem exists only if there is a construction by which the problem can be solved. The theorems that can be proved determine how an agent perceives a set of alternatives. A dual model relates perceived alternatives to a shared language, which the agents use in trading. So perceptions relate objective alternatives to an agent’s subjective view of them, and reporting dually relates an agent’s subjective world to a shared language. It turns out that an appropriately modified notion of competitive equilibrium always exists. However, in contrast with standard results in economic theory, competitive equilibrium need not be efficient.

     

Survey Nonrespondents as Bad Soldiers: Examining the relationship between organizational citizenship and survey response behavior

The present paper examines whether organizational survey response behavior relates to organizational citizenship behavior (OCB). In Study 1, we examined the relationship between OCB dimensions and survey completion intentions in a field setting (n=228). In Study 2, we compared respondents and different groups of nonrespondents on OCB dimensions using an experimental design in a university setting (n=622). Survey response and OCBs were found to be related. OCB research may suffer from nonresponse bias, with organizational surveys failing to capture the opinions of those least likely to engage in OCBs.     

The moderating role of consumer entitlement on the relationship of value with customer satisfaction

This research provides an extension of Oliver's (1980) expectancy disconfirmation model of satisfaction by examining the moderating role of consumer entitlement in the relationships between service quality and perceived value with customer satisfaction. Using a sample of season ticket holders of the National Hockey League franchise in the southeastern USA (n = 234), we found that consumer entitlement moderates the relationship of value with satisfaction, such that the impact of consumer‐perceived service value on satisfaction is mitigated for highly entitled consumers. That is, the positive value–satisfaction relationship is stronger for individuals low in consumer entitlement. This finding suggests that highly entitled consumers' satisfaction judgments are dominated by expectations, while less entitled consumers rely more on disconfirmation assessments. Strengths, limitations, suggestions for future research, and practical implications are offered. Copyright © 2015 John Wiley & Sons, Ltd.     

Attributions and Appraisals of Workplace Incivility: Finding Light on the Dark Side?

Ample research demonstrates that workplace incivility has individual and organisational costs, but an important question remains unanswered: might it have benefits as well? We investigate this possibility by focusing on incivility appraisals—both negative and challenge appraisals (i.e. as an opportunity for learning, growth)—and their correlates. To explain this diversity of appraisals, we examine whether attributions (i.e. perceived intent to harm, perceived perpetrator control) predict perceptions. We conducted two multi‐method (quantitative and qualitative) surveys, one of which was multi‐source, of employees across a range of occupations. In Study 1, attributions that perpetrators acted with control and malicious intent fuelled negative appraisals of incivility, which undermined job satisfaction. Study 2 added to these findings by demonstrating that some targets formed challenge appraisals of uncivil encounters, especially when they attributed low malicious intent to perpetrators; challenge appraisal related to boosts in job satisfaction and thriving. These attitudinal outcomes then positively related to organisational citizenship behaviour, as reported by targets' coworkers. Showing paths to incivility harm (and potential benefit), our findings can inform interventions to alter the impact of workplace incivility.     

Socially Explosive Minds: The Triple Imbalance Hypothesis of Reactive Aggression

ABSTRACT The psychobiological basis of reactive aggression, a condition characterized by uncontrolled outbursts of socially violent behavior, is unclear. Nonetheless, several theoretical models have been proposed that may have complementary views about the psychobiological mechanisms involved. In this review, we attempt to unite these models and theorize further on the basis of recent data from psychological and neuroscientific research to propose a comprehensive neuro-evolutionary framework: The Triple Imbalance Hypothesis (TIH) of reactive aggression. According to this model, reactive aggression is essentially subcortically motivated by an imbalance in the levels of the steroid hormones cortisol and testosterone (Subcortical Imbalance Hypothesis). This imbalance not only sets a primal predisposition for social aggression, but also down-regulates cortical–subcortical communication (Cortical-Subcortical Imbalance Hypothesis), hence diminishing control by cortical regions that regulate socially aggressive inclinations. However, these bottom-up hormonally mediated imbalances can drive both instrumental and reactive social aggression. The TIH suggests that reactive aggression is differentiated from proactive aggression by low brain serotonergic function and that reactive aggression is associated with left-sided frontal brain asymmetry (Cortical Imbalance Hypothesis), especially observed when the individual is socially threatened or provoked. This triple biobehavioral imbalance mirrors an evolutionary relapse into violently aggressive motivational drives that are adaptive among many reptilian and mammalian species, but may have become socially maladaptive in modern humans.     

The right parahippocampal gyrus contributes to the formation and maintenance of bound information in working memory

Working memory is devoted to the temporary storage and on-line manipulation of information. Recently, an integrative system termed the episodic buffer has been proposed to integrate and hold information being entered or retrieved from episodic memory. Although the brain system supporting such an integrative buffer is still in debate, the medial temporal lobe appears to be a promising candidate for the maintenance of bound information. In the current work, binding was assessed by comparing two conditions in which participants had to retain three letters and three spatial locations presented either bound or separate. At the behavioral level, lower performance was found for bound information than for separate information. When contrasting the two conditions, activation in the right parahippocampal gyrus was greater for the encoding and maintenance of bound information. No activation was observed in the medial temporal lobe during the retrieval of bound information. Together, our results suggest that the parahippocampal gyrus may underlie the integrative and maintenance functions of the episodic buffer.     

Peer Tutoring for Reading Fluency as a Feasible and Effective Alternative in Response to Intervention Systems

Peer tutoring is an evidence-based procedure for improving academic performance for a variety of skill areas. The current study evaluated the feasibility and impact of a peer tutoring package for reading fluency with 4 middle school students receiving Tier II remedial supports. This study used a multiple baseline design across participants to evaluate impact of the peer tutoring procedure on students’ oral reading rate on instructional passages. Results indicated that students’ oral reading rate on instructional probes increased following implementation of the peer tutoring procedure. Moreover, peer tutors implemented most steps of the procedure with a high degree of integrity. Results are discussed in terms of contributions to the peer tutoring and Response to Intervention literatures, as well as application to applied practice.
