Conflict,consensus, and liberty in J. S. Mill’s representative democracy

The relationship between representative democracy and conflict in John Stuart Mill’s political philosophy has been interpreted in very different ways. While some scholars claim that Millian democracy is incompatible with political conflict, others identify in Mill a radical political agonism that would offer a non-consensual model of deliberative democracy. This paper argues that neither of these views is exactly accurate: although he highlights the centrality of conflict in political life, Mill believes that democratic deliberation presupposes a minimal level of consensus regarding the formal value of democracy’s basic principles, viz. the principles of individual freedom and equality. Initially, I shall reconstruct the relationship between conflict and consensus in Mill’s conception of representative democracy. I shall then investigate his association of representation and advocacy and show that Mill’s encomium on political conflict was influenced by Guizot’s work. Finally, I shall explain how a democratic debate riven with conflict is conducive to individual freedom.     

An Examination of the Relationships Between Turnover Functionality, Turnover Frequency, and Organizational Performance

Meta-analysis was employed to investigate the relationships between organizational performance, as measured by sales growth, and turnover functionality and between organizational performance and turnover frequency. Turnover functionality was found to be correlated with organizational performance while turnover frequency was not.     

Personal values as a mediator between parent and peer expectations and adolescent behaviors.

The current study examined the mediating role of adolescents' personal values on the relation between maternal and peer expectations for prosocial behaviors and adolescents' self-reported prosocial and antisocial behaviors. One hundred thirty-four adolescents (mean age = 16.22 years, 54% girls) completed measures of their own values and behaviors, as well as their perceptions of the positive expectations that their mother and their best friend(s) had for their (the adolescents') prosocial behaviors. Stepwise regression analyses suggested that adolescents' personal prosocial values mediated the relation between adolescents' perceptions of both maternal and peer expectations and adolescents' prosocial behaviors. In addition, for boys, perceptions of positive peer expectations were directly and negatively related to antisocial behaviors. The current study has important implications for parents, educators, and practitioners who are concerned about promoting adolescents' positive behaviors and discouraging negative behaviors.     

General guidelines for conducting behavior modification programs in public school settings

Tentative guidelines for initiating behavior modification programs are presented. Discussion focuses on the importance of initial introduction of these procedures to teachers, the relation of teacher personality variables to technique selection, factors to consider when evaluating children for modification, and suggestions for on-going participation and withdrawal of the psychologist as an active agent in such programs.     

'Silent' priming of translation-dependent LTP by ß-adrenergic receptors involves phosphorylation and recruitment of AMPA receptors

The capacity for long-term changes in synaptic efficacy can be altered by prior synaptic activity, a process known as "metaplasticity." Activation of receptors for modulatory neurotransmitters can trigger downstream signaling cascades that persist beyond initial receptor activation and may thus have metaplastic effects. Because activation of β-adrenergic receptors (β-ARs) strongly enhances the induction of long-term potentiation (LTP) in the hippocampal CA1 region, we examined whether activation of these receptors also had metaplastic effects on LTP induction. Our results show that activation of β-ARs induces a protein synthesis-dependent form of metaplasticity that primes the future induction of late-phase LTP by a subthreshold stimulus. β-AR activation also induced a long-lasting increase in phosphorylation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) GluA1 subunits at a protein kinase A (PKA) site (S845) and transiently activated extracellular signal-regulated kinase (ERK). Consistent with this, inhibitors of PKA and ERK blocked the metaplastic effects of β-AR activation. β-AR activation also induced a prolonged, translation-dependent increase in cell surface levels of GluA1 subunit-containing AMPA receptors. Our results indicate that β-ARs can modulate hippocampal synaptic plasticity by priming synapses for the future induction of late-phase LTP through up-regulation of translational processes, one consequence of which is the trafficking of AMPARs to the cell surface.     

The effect of in-vehicle warning systems on speed compliance in work zones

The purpose of this research was to evaluate the effectiveness of augmented in-vehicle speed warnings on driver behavior in work zones. The influence of three device configurations were examined as the drivers entered a work zone which was presented in a simulated driving environment. The first configuration was a control condition which used only traditional signage. The second condition had the addition of a visual in-vehicle warning while the final condition had the addition of an auditory in-vehicle warning. Results indicated that adding in-vehicle warnings did affect driver compliance to the work zone speed limit. Participants in the audio warning condition responded more quickly to the warning than those in the visual condition. Both augmented warning configurations differed significantly and were each respectively different from the drivers in the control condition. Based on these results we suggest a combination of in-vehicle warnings. Upon entry of the work zone we suggest a combined audio and visual warning message. However, after the initial entry phase, a visual warning message shows greater promise for the on-going modulation of driver speed transit.
