Increasing driver yielding and pedestrian signaling with prompting, feedback, and enforcement

The effects of an intervention package on drivers' yielding to pedestrians and on pedestrians' signaling their intention to cross the street were assessed using a multiple baseline design. The intervention, which consisted of publicly posted feedback on the percentage of motorists yielding to pedestrians, small signs prompting pedestrians to engage in appropriate crossing behavior, and an enforcement program involving the use of warning tickets and feedback fliers, was sequentially introduced on two streets. The intervention more than doubled the percentage of motorists yielding to pedestrians and increased the percentage of pedestrians signaling their intention to cross the street to over 13% from a baseline level of less than 1%. Near misses involving pedestrians decreased by more than 50% on the narrower of the two streets.     

From interrogation to investigative interviewing; strategic trends in police questioning

The Court of Appeal has recently released a number of people who were convicted of serious charges because it could no longer rely on confessions obtained during Police questioning. A detailed questionnaire study in 1987 of 80 detectives at four busy inner-London Police Stations indicated that there had been improvements in the way Police question suspects. This is a result of the combined effects of new legislation, technology, and organizational policies designed to encourage an ethical approach to investigation. The majority of detectives have moved away from questioning purely to obtain a confession, towards questioning that is more of an inquiry—examining and adding to the existing evidence. However, a small number of detectives still indicated a preference for a dominant, confrontational style of interviewing, which stands in marked contrast to the majority emphasis on co-operative interviewing styles. It appeared from this study that the legislation would succeed in making the questioning of suspects less inherently coercive. Subsequent empirical studies have shown this trend to be continuing. The concept of ‘investigative interviewing’ as an alternative to interrogation has been developed with the assistance of psychologists and is being promoted through a national training programme intended to restore confidence in evidence obtained through Police questioning.     

美军EPAS系统对我军士兵职业分类研究的启示

EPAS（Enlisted Personnel Allocation System）是美军新开发的军人选拔分配系统。该系统采用最优线性匹配程序,通过预测绩效最大化,提高应征人员岗位匹配的有效性,以满足部队兵员分配的需求。本文从美军应征人员分配标准出发,介绍了该系统的历史沿革、主要原理,并阐明了对我军士兵职业分类研究的启迪。     

Effet des représentations et des conditions d’activités sur l’épuisement professionnel des policiers français dans un contexte de réformes

The purpose of this article is (1) to test the hypothesis of the primacy of subjective factors (professional representations) compared to objective factors of activity (ratio of police to population and ratio of police to reported offences) and sociobiographic factors (age and seniority), in the determination of the professional exhaustion expressed by French policemen in the current context of administrative reforms. A determination of professional representations and professional exhaustion by the status of the policemen are also advanced (2). The empirical study (N=143) confirmed these expectations and allowed to engage a psychosocial analysis concerning identity issues connected to professional representations within the framework of politics of prevention of the police professional exhaustion.     

“To serve and protect” when expecting to be seen negatively: The relation between police officers' contact with citizens,meta‐stereotyping,and work‐related well‐being

We examined the relationship between contact of police officers with citizens, their (meta‐)stereotypes about citizens, and their work‐related well‐being. Ninety‐three police officers from 4 police stations in low‐ and high‐crime regions in France completed the questionnaire. As expected, negative well‐being of police officers is predicted by negative contact with citizens and their belief that police officers are stereotyped negatively by citizens. Moreover, the relationship between negative contact and negative well‐being was mediated by police officers' beliefs that police officers are perceived negatively by citizens, whereas their perceptions of citizens did not mediate this relationship. Interestingly, level of crime did not influence these relationships. Together, this research shows the important role of beliefs about how one's group is stereotyped when in contact with another group as it may have consequences for people's well‐being.     

Police officers' use of evidence to elicit admissions in a fictitious criminal case

We examined how police officers planned to interview suspects in a situation where they lacked information about a critical phase of a crime (i.e., the time during which the crime took place) but possessed information about less critical phases of the crime (i.e., the time before and/or after the crime took place). The main focus was the officers' planned use of the available information (evidence) to elicit admissions about the critical phase. A survey was distributed to police officers (n  = 69) containing a fictitious murder case for which they were to prepare an interview with a suspect. The investigators planned to disclose the evidence more often in a strategic manner (obtaining the suspect's statement and exhausting alternative scenarios before revealing the evidence) than in a non‐strategic manner (revealing the evidence before requiring an explanation). The investigators' most frequently reported reason for their planned evidence use was to collect additional information about the particular phase to which the disclosed evidence pertained. It was rare that the investigators planned to disclose the evidence about a less critical phase of the crime in order to elicit admissions about the more critical phase (e.g., by disclosing the evidence to try to shift the suspect's counter‐interrogation strategy from less to more forthcoming). The investigators may benefit from recent research showing that strategic evidence disclosure can be used as a means to elicit admissions about a phase of a crime for which information is lacking.     

Relation between police image and police visibility

The purpose of this study was to build a model for the public image and visibility of the police. These variables were seen as central to successful community policing. Explanatory variables included were contacts with the police, victimisation and background characteristics of the respondents. Questionnaire data were obtained from a sample of 3271 adults (mean age 42) and 986 youngsters (mean age 15.5) in two Finnish cities. Using multi‐sample structural equation modelling, a four‐factor model with two image factors (Friendliness and Closeness) and two visibility factors (Patrol‐Car‐Related and Police‐on‐Foot Activities) was confirmed by the data. As hypothesised, for both adults and youngsters, seeing police‐on‐foot activities was positively correlated with both image factors, while seeing Patrol‐Car‐Related Activities was negatively correlated with police image. Relationships of explanatory variables with image factors were to a large extent but not completely mediated by the visibility factors. Some differences were found between adults and youngsters in factor means and in regression relationships. Quality of police visibility proved to be an important factor from the point of view of community policing, in which one of the main purposes is to improve the relationship between the police and the public.

The influence of an emotional processing strategy on visual threat detection by police trainees and officers

Threat detection is an important skill for police officers, but few studies have examined the impact of processing strategies on this ability. The first aim of our study was to compare the visual detection of threatening and neutral targets in 38 police trainees and 53 police officers. The other aims were to examine the effect of emotional or semantic strategies on this process and the effect of psychopathological symptoms. In a visual search task, participants had to detect a threatening or neutral target among neutral distractors. Participants answered a question used to induce a more emotional or semantic processing strategy. Results revealed that threatening targets were detected faster than neutral ones. This effect was enhanced with an emotional processing strategy but unaffected by symptoms. Processing strategy also had led to faster reaction time overall. This study shows that inducing processing strategies can influence threat detection in police trainees and officers.
