The applicability of a helicopter patrol procedure to diverse areas: A cost-benefit evaluation

The residential burglary deterrent effects of a helicopter patrol procedure were investigated in four separate areas with a multiple baseline technology. The helicopter was flown during an 8:00 a.m. to 4:00 p.m. period in two high density population areas of approximately 9.82 and 14.71 square miles and two low density population areas of 117.49 and 89.97 square miles. The helicopter patrol reduced residential burglaries without crime displacement in the two high density areas but had no deterrent effects in the low density areas. The costs of the helicopter patrol were justified by the benefits that resulted from the reduced home burglaries in the two high density areas. Because the helicopter patrol program is funded by general tax revenues, there is a disparity between those people paying for the procedure (all residents of Nashville) and those citizens that receive the burglary deterrent benefits (only residents of high-density areas). This distribution of benefit limitation suggests two courses of action: (1) The helicopter should be flown only in high population density areas even though the low population density areas are also victimized by high burglary rates. (2) A more comprehensive burglary reduction program must be developed so that effective deterrence can be realized in low density areas. These latter techniques would supplement helicopter patrol strategies and thus form a comprehensive burglary deterrent package that has an equitable benefit distribution.     

Rating of perceived effort but relative to what? A comparison between imposed and self-selected anchors

PurposeCollecting reliable and valid rating of perceived effort (RPE) data requires properly anchoring the scales’ upper limits (i.e., the meaning of 10 on a 0–10 scale). Yet, despite their importance, anchoring procedures remain understudied and theoretically underdeveloped. Here we propose a new task-based anchoring procedure that distinguishes between imposed and self-selected anchors. In the former, researchers impose on participants a specific task as the anchor; in the latter, participants choose the most effortful task experienced or imaginable as the anchor. We compared the impact of these conceptually different anchoring procedures on RPE.MethodsTwenty-five resistance-trained participants (13 females) attended a familiarization and two randomized experimental sessions. In both experimental sessions, participants performed non-fatiguing and fatiguing isometric maximal voluntary contraction (MVC) protocols with the squat followed by the gripper or vice versa. After each MVC, participants reported their RPE on a 0–10 scale relative to an imposed anchor of the performed task (e.g., gripper MVCs anchored to a gripper MVC) or to a self-selected anchor.ResultsIn the non-fatiguing condition, imposed anchors yielded greater RPEs than self-selected anchors for both the squat [on average, 9.4 vs. 5.5; Δ(CI_95%) = 3.9 (3.2, 4.5)] and gripper [9.4 vs. 3.9; Δ = 5.5 (4.7, 6.3)]. Similar results were observed in the fatiguing condition for both the squat [9.7 vs. 6.9; Δ = 2.8 (2.1, 3.5)] and gripper [9.7 vs. 4.5; Δ = 5.2 (4.3, 5.9)].ConclusionsWe found large differences in RPE between the two anchors, independent of exercises and fatigue state. These findings provide a basis for further development and refinement of anchoring procedures and highlight the importance of selecting, justifying, and consistently applying the chosen anchors.     

A review of reinforcement control procedures

A demonstration of the effects of reinforcement requires comparison of response rates in the presence of a contingency with those in another condition that controls for the influence of extraneous variables. We describe several control conditions that have been used in evaluating the effects of positive and negative reinforcement. The methodological rigor and practical utility of each type of control condition are discussed, and recommendations for the use of these conditions are presented.     

The phenomenology of protest atmosphere: A demonstrator perspective

This paper aims to improve our understanding of demonstrators' atmosphere perceptions, that is, demonstrators' affective state, which is induced by the protest environment. We examined how demonstrators perceive protest atmosphere, why they do so, and whether atmosphere perceptions influence demonstrators' future collective action preparedness. We hypothesized that demonstrators' atmosphere perceptions diverge on a dimension of pleasure, and relate to their grievance (i.e., perceived societal intolerance), group identification, empowerment, and perceived police aggression. A pleasant atmosphere perception was expected to stimulate a demonstrator's future action preparedness. We tested these hypotheses with a mixed‐methods dataset of two Dutch protests, staged by Lesbians, Gays, Bisexuals, and Transgenders and anti‐monarchists. Our analyses revealed that demonstrators' atmosphere perceptions diverge on a dimension of pleasure, and relate to group identification, empowerment, and, for anti‐monarchists, perceived societal intolerance. A pleasant atmosphere perception deters a demonstrator's future action preparedness and also stimulates his or her group identification and empowerment, which, then, stimulate his or her action preparedness.

Police interview competencies: assessment and associated traits

The present study empirically examines the structure of police interview competencies in self‐reports of 230 police investigators suggesting five major underlying dimensions, that is, ‘Careful‐tenacious’, ‘Controlled‐non‐reactive’, ‘Dominant‐insisting’, ‘Communicative’ and ‘Benevolent’. These dimensions discriminate performance in a series of interview vignettes, grouped in terms of type of case (interviewing a suspect, a witness or a victim) and type of suspect. In addition self‐ratings on these dimensions are related to self‐estimated interview effectiveness in the same vignettes. Participants are further administered the NEO PI‐R (Costa, P. T., & McCrae, R. R. (1992). Professional manual: Revised NEO personality inventory (NEO‐PI‐R) and NEO five‐factor‐inventory (NEO‐FFI). Odessa, FL: Psychological Assessment Resources), enabling an examination of the relationship between the competence dimensions and their personality trait building blocks. The implications of this study for the development and coaching of police interview competencies are discussed. Copyright © 2006 John Wiley & Sons, Ltd.     

Who Should Get a Say? Race,Law Enforcement Guidelines,and Systems of Representation

Most citizens agree that legislators should reflect their constituencies' stances. Yet constituents rarely speak in a single voice. Instead, constituents often vary not only in their policy preferences, but also in the degree to which a given policy impacts their lives. Politicians thus at times pursue targeted representation, offering increased input to especially affected groups. As efforts to address anti-Black police misconduct make clear, such measures can protect vulnerable minority groups—but they may also be perceived to sideline the less-affected majority. We fielded two national survey experiments to investigate how Americans respond when legislators give more attention to some citizens than others. Results suggest that members of targeted groups react more positively on average than nonmembers and that reactions among nonmembers are strongly driven by racial resentment. The impact of racial resentment is largely unaffected by the race and partisanship of the politician proposing the measure, but it is exacerbated in cases of a clear preference conflict between the African American community and the broader constituency.     

The role of work experience and individual beliefs in police officers' perceptions of date rape: An integration of quantitative and qualitative methods

Surveyed police officers from two police departments in the Midwest on their perceptions of date rape (N=91). The aim of this research was to examine the influence of officers' work experiences and general beliefs about women on their perceptions of date rape. Two approaches were utilized. First, using quantitative structural-equation modeling, a model that integrated work experiences and individual beliefs was evaluated using LISREL VII. Results suggest a direct path from the work experience variables to perceptions of date rape: Officers with more experience with rape cases held more sympathetic beliefs about data rape and date rape victims. Officers who found their training on rape to be very helpful, and those who reported that their work environment was sexualized and sexual harassment was a problem, were also less victim blaming. An indirect influence of these variables was also supported. Officers with more experience, those who perceived their training as helpful, and those with heightened awareness of sexual harassment in the workplace also held more favorable attitudes toward women, which, in turn, predicted less victim-blaming perceptions of date rape. Second, qualitative methods were used to have the police define and describe in their own words what has shaped their beliefs about date rape. These narratives were content analyzed by two raters. The qualitative results validated the quantitative findings as the officers were most likely to mention professional experience with rape cases and departmental trainings as important factors that changed their opinions. Work climate and personal experiences were also cited as influential. Implications for integrating qualitative and quantitative methods in research, and training interventions with police are discussed.

Changes in self-concept during occupational socialization of new recruits to the police

In a cross-sectional study five groups of male recruits (n = 369; ages 21 to 36) to a large English provincial police force were tested: one group at entry, three groups at different stages of their 2-year probationary period (one at one-quarter, one at one-half and one at three-quarters of the way through) and one immediately after the probationary period. Significant group effects were found on all 27 items of a set of self-concept statements, suggesting effects of entry-level occupational socialization on recruits' self-image. Changes from group to group during the course of training were examined using discriminant function analysis. Factor analysis yielded four clusters of items: isolation/vulnerability, tension/apprehension, self-worth and commitment/empathy; scores on all four fluctuated during training. Isolation and apprehension rose from a low base during training, and self-worth fell from a high base, but entry levels were recovered by completion of training, giving support for a weak version of the U-curve hypothesis of adaptation. However, high levels of commitment and empathy at entry were significantly depressed on completion of training. In addition, older trainees reported lower self-worth and higher apprehension. Results are interpreted in terms of adaptation during occupational socialization towards a more instrumental and cynical operational style.     

Latent inhibition in within-subject designs: The roles of masking, schizotypy, and gender

Latent inhibition (LI) is defined as poorer associative learning with a previously exposed, irrelevant stimulus than with a non-preexposed, novel stimulus. This study examined how type of within-subject procedure, class of schizotypal symptoms, and gender modulate LI. Two within-subject procedures were examined, one excluding, and one including a masking task. The former yielded a stronger stimulus preexposure effect than the latter. However, the stimulus preexposure effect was attenuated by total schizotypy score in the masked, but not in the non-masked procedure. The results with schizotypy factors (positive and negative symptoms) as well as with schizotypy factors × gender interactions were inconsistent with those of other studies. It was suggested that in addition to LI, interference and novel pop-out effects were also produced by the procedures, particularly in the non-masked condition.
