The proliferation of recording technologies has increased the prevalence of police intervention videos in news media. Although previous research has explored the influence of such coverage on public opinion, the mechanisms underlying this impact have received limited attention. This study investigates the role of information credibility in the assessment of police interventions portrayed in news media videos.

A total of 634 participants were shown a mock-up TV news report that included a description and a brief clip of a police use-of-force event. A survey was conducted before and after the presentation of the report.

Camera perspective, anchor tone, viewer gender and pre-existing perceived TV news credibility were found to influence how credible the mock-up news report was perceived. Participants who judged the news report as complete and credible tended to have a more favourable opinion of the police intervention. Perceived credibility also acted as a moderator in the relationship between video and receiver characteristics and the assessment of the police intervention.

These findings offer valuable insights for law enforcement agencies and their public affairs units to develop effective strategies for managing public opinion.

This research highlights how important perceived credibility is in influencing public opinion and how different factors such as video and receiver characteristics can impact credibility assessment.

Oleoresin capsicum (OC) spray has proven to be a relatively effective tool to subdue resistant or aggressive subjects without causing major and permanent injuries. Several products are available to law enforcement organizations and sprays with higher concentrations are sold as more effective, despite the lack of empirical evidence. This article aims to test the proposition that more concentrated OC sprays are more effective in a policing context.

To test this proposition, retrospective data on police interventions that had occurred (N = 1,019) were used. Concentrations were divided in three levels: level 1 sprays (containing up to 0.49% of major capsaicinoids), level 2 sprays (from 0.5% to 0.99%) and level 3 sprays (between 1 and 1.33%). Propensity scores were calculated to estimate the average effect of concentration level on effectiveness, while controlling for confounding factors.

Level 1 and level 2 sprays were found to be similar in terms of effectiveness, but level 3 sprays were found to be more likely to have an immediate effect but were also related to higher chances that decontamination was needed after use.

While several studies of the effectiveness of OC spray in general have been conducted in the past, this is one of the few to differentiate types of OC sprays according to their concentration level. As such, it aims to provide guidance to police organizations who must choose among a variety of products.

The purpose of this paper is to analyze the spatial patterns of different phenomena in the same geographical space. Andresen’s spatial point pattern test computes a global index (the S-index) that informs on the similarity or dissimilarity of spatial patterns. This paper suggests a generalized S-index that allows perfect similarity and dissimilarity in all situations.

The relevance of the generalized S-index is illustrated with police data from the San Francisco Police Department. In all cases, the original S-index, its robust version – which excludes zero-crime areas – and the generalized alternative were computed.

In the first example, the number of crimes greatly exceeds the number of areas and there are no zero-value areas. A key feature of the second example is that most street segments were free of any criminal activity in both patterns. Finally, in the third case, one type of event is considerably rarer than the other. The original S-index is equal to the generalized index (Case 1) or theoretically irrelevant (Cases 2 and 3). Furthermore, the robust index is unnecessary and potentially biased when the number of at least one phenomenon being compared is lower than the number of areas under study. Thus, this study suggests to replace the S-index with its generalized version.

The generalized S-index is relevant for situations when events are relatively rare –as is the case with crime – and the unit of analysis is small but plentiful – such as addresses or street segments.

In most jurisdictions, resistance is the primary legal justification for police use of force. Identifying the correlates of resistance helps to anticipate non-compliance, increase officer safety, and maintain low rates of use of force. Following previous research on subject demeanor, the purpose of this paper is to argue that the presence of resistance is determined subjectively, based on an individual’s interpretation of a situation.

Binary and multinomial logistic regression models were used to analyze resistance reported in 878 interventions involving police use of force in a large Canadian city. A four-category measure similar to those commonly found in previous studies was used to build dependent variables and a series of 14 behaviors based on the actions of a subject was used as a predictor of reported resistance.

As expected, subject behavior was found to be a significant predictor of reported resistance. Officer and citizen characteristics (gender, race, age/experience) were weakly related to the outcome. Models were found to offer considerably better predictions when situational factors were included.

Perceptions of resistance were found to be influenced by a variety of factors, including, but not limited to, the subject’s actions.

The use of polysaccharides increases solubility and consistency and causes functions such as viscosity? Moisture and food emulsifier stabilizer. This study aims to enrich the formulation of low-fat mozzarella cheese using microcoated vitamin D3 (VD3).

This study investigates the addition of hydrocolloids to low-fat mozzarella cheese to enhance its properties and nutritional value. Tests were conducted on cheese samples with 0.05% and 0.25% hydrocolloid concentrations at various stages: before production and at three and six months’ postproduction. The samples were evaluated for elasticity, pH and solubility to select the best one, which was then fortified with VD3. The vitamin was microencapsulated using alginate and whey protein to shield it from light and oxygen, optimizing the formula using the response surface method. The fortified cheese was tested for VD3 content over its shelf life.

Results indicated that all hydrocolloids tested improved moisture and meltability of the cheese while higher protein levels increased stretchability two to threefold. Rice starch hydrocolloid at 0.05% concentration was chosen due to superior sensory scores and minimal oil separation. This study concluded that VD3 levels remained stable during the cheese’s shelf life, suggesting that this approach could enhance the nutritional value of low-fat cheese without compromising its quality. Therefore, after examining the obtained results and comparing the regression models, the results indicated that the Quadratic model was chosen to investigate the effect of independent variables on the response rate, which had a statistically significant difference with other models (p = 0.0019). Also the results of the area under the curve and using the encapsulation efficiency equation, the percentage of microencapsulated vitamin was obtained, and according to the simulation results, the encapsulation efficiency was reported as 89.02%.

Developing innovative functional dairy products fortified with VD3 could improve the vitamin D status in deficient populations. Therefore, these designs can be applied at industrial scales for functional cheese production.
