    On the dual motivational force of legitimate authority

    Get PDF
    In this chapter I consider two ways by which the legitimacy of legal authorities might motivate people to abide by the law. Following recent criminological research I define legitimacy along two different dimensions: the first is the public recognition of the rightful authority of an institution, and the second is a sense among citizens that the institution is just, moral and appropriate. Data from a randomized controlled trial of procedurally just policing provide further support for the idea that justice systems can secure compliance by (a) instilling in citizens a sense of deference and obligation, and (b) showing to citizens that they represent a requisite sense of moral appropriateness. While prior work has tended to focus on the idea that legitimacy shape compliance through felt obligation, the current analysis shows that compliance is predicted by both duty to obey and moral endorsement. Consistent with a good deal of existing evidence, the findings also indicate the importance of procedural justice and group identification in the production of institutional legitimacy. I conclude with the idea that legitimacy may be able to shape compliance through shape content-free obligation and shared moral appropriateness

    Spectral equalization in binaural signals represented by order-truncated spherical harmonics

    The synthesis of binaural signals from spherical microphone array recordings has been recently proposed. The limited spatial resolution of the reproduced signal due to order-limited reproduction has been previously investigated perceptually, showing spatial perception ramifications, such as poor source localization and limited externalization. Furthermore, this spatial order limitation also has a detrimental effect on the frequency content of the signal and its perceived timbre, due to the rapid roll-off at high frequencies. In this paper, the underlying causes of this spectral roll-off are described mathematically and investigated numerically. A digital filter that equalizes the frequency spectrum of a low spatial order signal is introduced and evaluated. A comprehensive listening test was conducted to study the influence of the filter on the perception of the reproduced sound. Results indicate that the suggested filter is beneficial for restoring the timbral composition of order-truncated binaural signals, while conserving, and even improving, some spatial properties of the signal

    OBJECTIVES: Autocrine and paracrine chemokine/chemokine receptor-based interactions promote non-small-cell-lung-cancer (NSCLC) carcinogenesis. CCL20/CCR6 interactions are involved in prostatic and colonic malignancy pathogenesis. The expression and function of CCL20/CCR6 and its related Th-17 type immune response in NSCLC is not yet defined. We sought to characterize the role of the CCL20/CCR6/IL-17 axis in NSCLC tumor growth. METHODS: A specialized histopathologist blindly assessed CCL20/CCR6 expression levels in 49 tissue samples of NSCLC patients operated in our department. Results were correlated to disease progression. Colony assays, ERK signaling and chemokine production were measured to assess cancer cell responsiveness to CCL20 and IL-17 stimulation. RESULTS: CCL20 was highly expressed in the majority (38/49, 77.5%) of tumor samples. Only a minority of samples (8/49, 16.5%) showed high CCR6 expression. High CCR6 expression was associated with a shorter disease-free survival (P = 0.008) and conferred a disease stage-independent 4.87-fold increased risk for disease recurrence (P = 0.0076, CI 95% 1.52-15.563). Cancerous cell colony-forming capacity was increased by CCL20 stimulation; this effect was dependent in part on ERK phosphorylation and signaling. IL-17 expression was detected in NSCLC; IL-17 potentiated the production of CCL20 by cancerous cells. CONCLUSION: Our findings suggest that the CCL20/CCR6 axis promotes NSCLC disease progression. CCR6 is identified as a potential new prognostic marker and the CCL20/CCR6/IL-17 axis as a potential new therapeutic target. Larger scale studies are required to consolidate these observations

    Measuring “waiting” impulsivity in substance addictions and binge eating disorder in a novel analogue of rodent serial reaction time task

    Get PDF
    Background Premature responding is a form of motor impulsivity that preclinical evidence has shown to predict compulsive drug seeking but has not yet been studied in humans. We developed a novel translation of the task, based on the rodent 5-choice serial reaction time task, testing premature responding in disorders of drug and natural food rewards. Methods Abstinent alcohol- (n = 30) and methamphetamine-dependent (n = 23) subjects, recreational cannabis users (n = 30), and obese subjects with (n = 30) and without (n = 30) binge eating disorder (BED) were compared with matched healthy volunteers and tested on the premature responding task. Results Compared with healthy volunteers, alcohol- and methamphetamine-dependent subjects and cannabis users showed greater premature responding with no differences observed in obese subjects with or without BED. Current smokers exhibited greater premature responding versus ex-smokers and nonsmokers. Alcohol-dependent subjects also had lower motivation for explicit monetary incentives. A Motivation Index correlated negatively with alcohol use and binge eating severity. Conclusions Premature responding on a novel translation of a serial reaction time task was more evident in substance use disorders but not in obese subjects with or without BED. Lower motivation for monetary incentives linked alcohol use and binge eating severity. Our findings add to understanding the relationship between drug and natural food rewards

    Fairness at Trial: The Impact of Procedural Justice and Other Experiential Factors on Criminal Defendants' Perceptions of Court Legitimacy in Poland

    Get PDF
    A large body of research supports the procedural justice hypothesis that quality of treatment matters more than outcomes for institutional legitimacy. How fairness matters across legal institutions and geographic settings remains an open question, however. This article uses a survey of criminal defendants to test the factors associated with perceived legitimacy of courts in Poland, a country whose judiciary is currently subject to intense political contestation. The findings confirm the primacy of procedural justice, while also illustrating the influence of instrumental performance factors such as time and court organization. This suggests that in contexts of political transition with disputed legal institutions, citizens’ contact with procedurally fair, operationally efficient institutions can support the legitimacy of authorities and strengthen the rule of law

    Enhancing public trust and police legitimacy during road traffic encounters:Results from a randomised controlled trial in Scotland

    Get PDF
    Objectives This paper reports results from the Scottish Community Engagement Trial (ScotCET), devised to replicate the Queensland Community Trial (QCET). ScotCET was an RCT that tested the effects of ‘procedurally just’ policing on public trust and police legitimacy Methods A block-randomized (matched pairs) design, with pretest and posttest measures, was implemented in the context of road policing in Scotland. Participants were drivers stopped by police in December and January 2013/14 as part of Police Scotland’s ‘Festive Road Safety Campaign’. The experimental intervention comprised a checklist of key messages to include in routine roadside vehicle stops, and a leaflet for officers to give to drivers. Analysis proceeds via random effects regression models predicting latent variable measures of trust, satisfaction and legitimacy Results Contrary to expectations the intervention did not improve trust and legitimacy; rather, trust in the officers who made the stop, and satisfaction with their conduct fell in the test sites, relative to the controls, after implementation of the intervention. The intervention had no significant effect on general trust in the police, or on police legitimacy. Conclusions Results demonstrate the difficulty in translating experimental interventions across policing contexts, and challenge the notion that public perceptions may be improved through a simple, additive approach to the delivery and communication of procedural justice.</p

    Endougenous Timing in a Mixed Duopoly

    This paper applies the framework of endogenous timing in games to mixed quantity duopoly, wherein a private domestic or foreign firm competes with a public, welfare maximizing firm. We show that simultaneous play never emerges as a subgame-perfect equilibrium of the extended game, in sharp contrast to private duopoly games. We provide sufficient conditions for the emergence of public and/or private leadership equilibrium. In all cases, private profits and social welfare are higher than under the corresponding Cournot equilibrium. From a methodological viewpoint we make extensive use of the basic results from the theory of supermodular games in order to avoid common extraneous assumptions such as concavity, existence and uniqueness of the different equilibria, whenever possible. Some policy implications are drawn, in particular those relating to the merits of privatization

    Police Responses to Terrorism: Lessons from the Israeli Experience

    No full text
    The purpose of this study is to examine the attitudes of Jews and Arabs in Israel concerning the role of the police in counterterrorism. The study focuses on the public perception of the effect of the police’s involvement in counterterrorism on their ability to perform traditional police roles; how the police’s role in fighting terrorism affects the relationship between police and the community; and the willingness of Jews and Arabs in Israel to assist the police by reporting crimes and terrorism threats. These questions are asked against the backdrop of majority-minority relations, in which the ways both the majority Jewish population and the minority Arab population in Israel responds are examined. Data included in this study was gathered from a community survey. The computer software “Dvash” and the database “Bezek,” which includes all residents of Israel who have "land" phone lines were used to conduct the survey. The low response rate (58%) of the community survey limits the extent to which the results can be applied to the entire Israeli population. Variables affecting the data gathered include the respondent’s past experiences with the po lice, their religion or ethnicity, their trust in the capabilities of the police, and their views on the consequences of policing terrorism
