The literature on cognitive distortions offers insight on why we continue to face reform challenges regarding police use of force- and citizen interaction-related outcomes. We used two studies of police officers to determine the extent to which one cognitive distortion—dichotomous thinking—was associated with problematic orientations about use of force and citizen interactions. In Study 1, we found that dichotomous thinking was associated with weaker support for de-escalation, procedural justice, and maintaining self-control during hypothetical citizen interactions. Dichotomous thinking also was associated with more support for force-related misconduct. Study 2 showed that officers who engaged in dichotomous thinking were more likely to perceive an immediate and serious threat from watching suspects in body-worn camera videos. Also, they were more likely to believe suspects had greater ability, opportunity, and intent to cause harm. We discuss the practical implications of these findings for policing and police reform.

With the anticipated population growth by 2050, the demand for high-quality protein for human consumption is set to rise. To enhance the sustainability of U.S. cattle production, producers and researchers have traditionally concentrated on improving the feed efficiency of steers through advancements in genetics, nutrition, and microbiome tools, resulting in a more marketable beef product. However, without successful pregnancies, there would be no marketable animals to feed. Despite extensive research on hormonal impacts on cattle physiology, including nutrition and reproduction, there is limited knowledge about how the rumen microbial environment is impacted by pregnancy and feed efficiency in female beef cattle. Understanding the rumen microbiome's role in feed efficiency and its response to hormonal changes during pregnancy is crucial for advancing sustainable beef cattle production. Therefore, this review highlights the importance of understanding the microbial dynamics in the rumen of pregnant beef females. Although progress has been made, gaps remain in understanding how varying nutritional requirements throughout pregnancy affect the rumen microbiome, highlighting the need for continued research. Addressing these areas will lead to more efficient and sustainable cattle production practices, benefiting beef production and contributing to global food security. [ABSTRACT FROM AUTHOR]

With an expected increase in population by 2050, the demand for high-quality protein for human consumption will increase. To improve the sustainability of US cattle production, producers and researchers have historically focused on improving the feed efficiency of steers through improvements in genetics, nutrition, and microbiome management, producing a more marketable beef product. However, without a successful pregnancy, there would be no marketable animal to feed. The objective of this study was to examine the impact of pregnancy on the rumen environment, microbial communities, and the correlation to feed efficiency status in Angus heifers. Utilizing 17 cannulated Angus heifers, feed efficiency status was determined using the GrowSafe 8000 feed intake monitoring system to monitor feed intake for a 70d trial period to calculate residual feed intake. Following the trial, heifers were bred and 40mL rumen fluid and content samples were collected every two weeks during gestation. Metagenomic DNA was extracted from the rumen samples, sequencing libraries were prepared targeting the bacterial V4 region of the 16S rRNA gene, and resultant libraries were sequenced on an Illumina MiSeq. All microbial analyses were conducted in the R environment v2.6.2 where alpha diversity, beta diversity, and differential abundances were determined. Metabolites were identified using ultra high-performance liquid chromatography high resolution mass spectrometry, and Metabolomic Analysis and Visualization Engine was used to select metabolite peaks. Differential abundance analyses using "ANCOMBC" indicated 10 amplicon sequence variants (ASVs), assigned to seven Prevotella and three Succiniclasticum , significantly varied among weeks of gestation (P <0.05). Based on a one-way ANOVA, 90 metabolites were determined significant throughout pregnancy (P <0.05). The 10 metabolites with the highest variable importance of projection scores from a partial least squares discriminant analysis were used to calculate correlations between. Of the 10 ASVs and 10 metabolites, significant correlations with feed efficiency status were found at various time points (P <0.05). The rumen microbiome and its fermentative profile were different at various time points during pregnancy with several correlations to feed efficiency status. Identifying pregnancy-related microbial and metabolite changes may aid producers to anticipate nutritional or management adjustments, ultimately contributing to the sustainability of beef production.

Concerns about excessive use of force by U.S. police have led to calls for agencies to move from 'warrior' to 'guardian' policing. 'Warrior' policing embodies an aggressive or coercive approach to law enforcement, while 'guardian' policing prioritises communication, procedural justice and citizen safety. Associations between guardian and warrior policing orientations and use of force attitudes in the U.S. have been found, however the influence of these orientations on police use of force in Australia has not been examined. This study examined the association of guardian and warrior policing orientations with use of force attitudes, threat perceptions and tactical decision-making among Australian officers, through a survey of 183 police officers in Queensland. Regression analyses indicated that warrior policing was associated with greater support for use of force and greater perceived threat in an ambiguous threat scenario, while guardian policing was associated with more restraint in tactical decision-making among Australian police officers.
