There is little evidence about "what works" in police training. The good news is that training evaluations are becoming more common. As we build this evidence base, we need to explore the factors that predict whether officers are receptive to the training programs they complete. We advance a theory of officer training motivation and receptivity that provides a useful framework for training evaluation and test it using survey data from a group of officers randomly assigned to a long-term, social interaction training program. The results demonstrate that trainees' internal locus of control was associated with their motivation to train. In turn, training motivation was associated with receptivity to the training (i.e., training satisfaction and perceived skill acquisition). Additionally, officers' evaluations of supervisor organizational justice were positively associated with perceived skill acquisition. We conclude the paper by discussing avenues for future refinement and testing of the theoretical framework. [ABSTRACT FROM AUTHOR]

Bulls often experience various levels of nutrient availability throughout the year. Nutritional management is a critical factor on overall ejaculate composition and the ability to get females pregnant. We hypothesized that differing nutritional levels and body condition score (BCS) affect reproductive fertility parameters in bulls. Mature Angus bulls (n  = 11) were individually housed and randomly assigned to one of two dietary regimens: 1) over-fed (n  = 5) or 2) restricted (n  = 6). Bulls were fed the same ration at different volumes to achieve desired effects resulting in eight individual treatments: gain to an over-fed body condition score ([BCS]; GO), gain after nutrient restriction (GR), loss after an over-fed BCS (LO), loss from nutrient restriction (LR), maintenance at ideal adiposity (BCS = 6) after overfeeding (IMO), maintenance at ideal adiposity after nutrient restriction (IMR), maintenance at an over-fed BCS (BCS = 8; MO), and maintenance at a restricted BCS (BCS = 4; MR). Body weight (BW) and BCS were recorded every 2 wk to monitor bull weight and BCS changes. Scrotal circumference was measured every 28 d. Body fat and sperm motility and morphology were evaluated every 84 d. Scrotal circumference, motility, and morphology were normalized to the initial value of each bull. Thus, allowing the individual bull to serve as a control. Statistical analyses were conducted with PROC GLIMMIX of SAS as a complete randomized design to determine if treatment influenced BW, BCS, scrotal circumference, motility, morphology, and adipose thickness. Scrotal circumference (P  < 0.001) had the least amount of deviation from initial during the LR (0.29 ± 0.44) treatment and the greatest during the MO (3.06 ± 0.44), LO (2.28 ± 0.44), MR (2.43 ± 0.44), GR (3.03 ± 0.44), and IMR (2.91 ± 0.44) treatments. Sperm motility was not affected by nutritional treatments (P  = 0.55). Both head and total defects of sperm differed (P  = 0.02) due to nutritional treatments. Increased head abnormalities occurred during the LO (37.60 ± 8.61) treatment, with no differences between the other treatments. Total defects increased during the LO (43.80 ± 9.55) treatment with similar increases in bulls during the GR (29.40 ± 9.55) and IMR (35.60 ± 9.55) treatments. In conclusion, male fertility was impacted when a deviation from a BCS of 6 occurred which could be detrimental to reproductive and beef production efficiency. [ABSTRACT FROM AUTHOR]

In an effort to provide a theoretical framework for understanding citizens' decisions to complain about the police, this paper suggests that citizen complaints can be viewed as a justice-restoring response and tests six hypotheses using a factorial vignette experiment. The findings indicate that individuals are more likely to complain when they perceive the interaction as procedurally unfair, distributively unfair, and when the outcome is unfavourable. Positive pre-existing attitudes towards the police result in an increased likelihood of engaging in a justice-restoring response. Despite drawing on Tyler's legitimacy theory, these findings differentiate justice-restoring responses from legitimacy by the comparatively greater impact of outcome favourability and the differing direction of the effect of pre-existing attitudes towards the police.

We hypothesized that maternal nutrition during the first 50 d of gestation would influence the abundance of hexose transporters, SLC2A1, SLC2A3, and SLC2A5, and cationic amino acid transporters, SLC7A1 and SLC7A2, in heifer uteroplacental tissues. Angus-cross heifers (n = 43) were estrus synchronized, bred via artificial insemination, and assigned at breeding to 1 of 2 dietary intake groups (CON = 100% of requirements to achieve 0.45 kg/d of BW gain or RES = 60% of CON intake) and ovariohysterectomized on day 16, 34, or 50 of gestation (n = 6 to 9/d) in a completely randomized design with a 2 × 3 factorial arrangement of treatments. Uterine cross-sections were collected from the horn ipsilateral to the corpus luteum, fixed in 10% neutral buffered formalin, sectioned at 5 µm, and stained via immunofluorescence for transporters. For each image, areas of fetal membrane (FM ; chorioallantois), luminal epithelium (ENDO), superficial glands (SG), deep glands (DG), and myometrium (MYO) were analyzed separately for relative intensity of fluorescence as an indicator of transporter abundance. Analysis of FM was only conducted for days 34 and 50. No transporters in target areas were influenced by a day × treatment interaction (P ≥ 0.06). In ENDO, all transporters were differentially abundant from days 16 to 50 of gestation (P ≤ 0.04), and SLC7A2 was greater (P = 0.05) for RES vs. CON. In SG, SLC7A1 and SLC7A2 were greater (P ≤ 0.04) at day 34 vs. day 16. In DG, SLC2A3 and SLC7A1 were greater (P ≤ 0.05) for CON vs. RES heifers; furthermore, SLC7A1 was greater (P < 0.01) at day 50 vs. days 16 and 34 of gestation. In MYO, SLC7A1 was greater (P < 0.01) for CON vs. RES and was greater (P = 0.02) at days 34 and 50 vs. day 16. There were no differences in FM (P ≥ 0.06). Analysis of all uterine tissues at day 16 determined that SLC2A1, SLC2A3, and SLC7A2 were all differentially abundant across uterine tissue type (P < 0.01), and SLC7A1 was greater (P = 0.02) for CON vs. RES. Analysis of all uteroplacental tissues at days 34 and 50 demonstrated that all transporters differed (P < 0.01) across uteroplacental tissues, and SLC7A1 was greater (P < 0.01) for CON vs. RES. These data are interpreted to imply that transporters are differentially affected by day of gestation, and that hexose and cationic amino acid transporters are differentially abundant across utero-placental tissue types, and that SLC7A1 is responsive to maternal nutritional treatment.

Policing experts have suggested that shifting from a warrior mindset – officers viewing themselves as warriors fighting crime – to a guardian mindset – officers valuing working with the public to reduce crime – is a valuable method for improving police-community relations across the United States. However, little empirical evidence has been used to inform this debate. To address this gap, we examined survey data from two U.S. police departments to assess the validity of the Warrior/Guardian framework. Factor analyses suggested that the warrior and guardian mindsets are distinct, but related concepts. Furthermore, these mindsets are associated with different attitudinal outcomes (e.g. the guardian mindset was associated with greater prioritization of communication during citizen encounters). Thus, the Warrior/Guardian framework is supported empirically. Overlap between the Warrior/Guardian framework and existing police culture literature is discussed and police culture is offered as a potential explanation for variation in warrior and guardian orientations.

Alternative stable states are nontransitory states within which communities can exist. However, even highly dynamic communities can be viewed within the framework of stable‐state theory if an appropriate "ecologically relevant" time scale is identified. The ecologically relevant time scale for dynamic systems needs to conform to the amount of time needed for a system's community to complete an entire cycle through its normal range of variation. For some systems, the ecologically relevant period can be relatively short (eg, tidal systems), for others it can be decadal (eg, prairie wetlands). We explore the concept of alternative stable states in unstable systems using the highly dynamic wetland ecosystems of North America's Prairie Pothole Region. The communities in these wetland ecosystems transition through multiple states in response to decadal‐long climate oscillations that cyclically influence ponded‐water depth, permanence, and chemistry. The perspective gained by considering dynamic systems in the context of stable‐state theory allows for an increased understanding of how these systems respond to changing drivers that can push them past tipping points into alternative states. Incorporation of concepts inherent to stable‐state theory has been suggested as a key scientific element upon which to base sustainable environmental management. [ABSTRACT FROM AUTHOR]

Controversial incidents involving uses of force by police in recent years have led to calls for improving officers' de-escalation skills. A more fruitful approach to police training reform may be a broader focus on improving officers' social interaction skills. By viewing all police-citizen encounters as social interactions that can either escalate toward or de-escalate away from the use of force, police training can develop what other fields call a "deliberate, repetitive practice" framework. This article describes the implementation of a randomized trial that brought such training to two U.S. police agencies and yielded encouraging results. We conclude that the conceptual framework was generally well received but that results depended heavily on the selection and performance of each agency's own trainers. [ABSTRACT FROM AUTHOR]

Objectives: A body of literature has demonstrated that the perceived legitimacy of legal authorities is an important predictor of criminal offending. Criminal offending is itself age-graded and good explanations of offending should offer some insight for how it changes as individuals age. This article attempts to address this gap by developing and testing seven hypotheses regarding how legitimacy changes over time. Method: Using panel data from the Pathways to Desistance study, a latent growth model (LGM) for legitimacy examines how evaluations of legitimacy change from adolescence to emerging adulthood as well as what factors influence this change. Results: During the period individuals were involved in the study, the LGM revealed that perceptions of legitimacy increase as individuals progress through adolescence before stabilizing in emerging adulthood. Several theoretical factors were related to individuals' legitimacy evaluations including parental evaluations of legitimacy, family support, emotionality, and self-control. Most importantly, perceptions of procedural justice were found to be related to legitimacy, but this relationship weakened as individuals aged. Conclusions: Evaluations of the legitimacy of legal authorities are, in fact, age-graded. Criminologists should continue to explore the sources of legitimacy evaluations in further developing legitimacy as an important theory of criminal behavior. [ABSTRACT FROM AUTHOR]
