Piercing the surface: A mechanical analysis of stabbing with household tools

Estimating the applied power during a stabbing incident, or estimating the minimal force necessary to penetrate the body with a certain weapon is a challenging task in forensic practice. A thorough forensic evaluation of stabbing forces needs objective numerical experimental data. Stabbing tests of 12 different weapons – including knives, a pair of scissors, a fork, screwdrivers, a rasp, a corkscrew, and a utility knife blade – were performed with a Mecmesin MultiTest-dV material tester on pork loin and ballistic gel to estimate the stabbing forces and dynamics. Penetration force (F_p) and maximal force (F_max) were recorded, and the registered force curves were analyzed. F_max was 159.8–212.07 Newton (N), 30.56–30.58 N, 168.9–185.48 N for various knives; 171.39–190.43 N for the pair of scissors, 233.6 N for the fork; 532.65–562.65 N, 370.31–367.19 N and 314.51–432.89 N for various screwdrivers, 44.14–56.62 N for utility knife during pork loin stabbing. The butter knife, corkscrew and rasp were not able to penetrate the pork loin, and the curved fork bent during stabbing. The results prove that weapon characteristics greatly influence the force necessary for penetration. Maximal stabbing force depends mostly on tip sharpness, and the force sharply decreases after penetration occurs, which indicates that edge sharpness is not as important as tip characteristics during stabbing perpendicular to skin surface. The penetration force during stabbing with a pair of scissors is comparable to the penetration force of knives. Stabbing with screwdrivers generally needs larger force than average knives but depends greatly on screwdriver size.     

Overview of the seized and examined pharmaceutical in the state of Minas Gerais-Brazil by the Civil Police from 2017 to 2022: A fundamental analysis of the recent impact over the drugs market

This work presents a data survey regarding the qualitative chemical analysis of drugs seized by the Police in the state of Minas Gerais between July 2017 and June 2022, including an evaluation of labeling of 265 samples of anabolic androgenic steroids (AAS) seized in 2020. The Active Pharmaceutical Ingredients (API) present in the samples were identified through chemical analysis and classified by system Anatomical Therapeutic Chemical (ATC) methods. Analysis of the labeling information for 265 samples of AAS followed the guidance of legislation RDC 71 (2009) from ANVISA. For this study 6355 seized pharmaceuticals underwent qualitative chemical analysis that corresponded to 7739 APIs successfully identified and classified. Among the components studied AAS, psychostimulants, anesthetics, and analgesics were the most commonly examined. AAS seized and tested increased by over 100% and for the majority of the samples analyzed were found to not match the labeling on the packaging. In the meantime, anti-obesity drugs presented a prominent increase of 400% from 2020/1 to 2021/2, during covid-19 quarantine. Seized pharmaceuticals and tests can support information in the planning of public health and safety policies.     

Accountability from the perspective of the forum: citizens’ attitudes towards accountability in Europe

The aim of this article is to analyse citizens’ attitudes towards governmental accountability in 24 European countries and to examine the influence of contextual and individual factors on perceptions of accountability. Using as a dataset the 2012 European Social Survey, the results show that citizens respond positively when the media provides reliable information on which to judge the government, when individuals perceive that governments perform well, when individuals live in more extensive and generous welfare states and when they live in countries where the rule of law is firmly established. In addition, the findings also provide evidence that compared to politically left-wing citizens, right-wing supporters have, on average, a higher perception of governmental accountability. In particular, the findings show strong positive evaluations of right-wing governments by right-wing voters in comparison with left-wing governments by left-wing voters.     

How Language Can Influence Political Marketing Strategy and a Candidate's Image: Effect of Presidential Candidates' Language Intensity and Experience on College Students' Ratings of Source Credibility

The present study examines the effects of language intensity on presidential candidates' credibility. We manipulated language intensity levels and experience levels for hypothetical candidates for president of the United States. Manipulation checks confirmed the effectiveness of the experimental conditions. The dimensions of source credibility, character, and authoritativeness were confirmed using confirmatory factor analysis. Analysis of variance indicated that candidates using low-intensity language received higher scores on character than did candidates using high-intensity language. Experienced candidates received higher scores on authoritativeness than did inexperienced candidates. Implications for political marketing of candidates are discussed.     

Who wants to pay more? The European Union's military operations and the dispute over financial burden sharing

In 2014, the European Union (EU) launched the sixth review of the Athena mechanism that finances the common costs of military operations launched in the framework of its Common Security and Defence Policy (CSDP). In the run up to the review, there were expectations that it would improve financial burden sharing in CSDP operations by expanding common funding for them. However, these hopes were disappointed; the review became a diplomatic tug of war between France, the strongest supporter of expanded common funding, and the UK, its strongest opponent. In the end, France agreed to the UK's terms to ensure that the existing level of common funding would not decrease. This article analyses the Athena review from a neoclassical realist perspective. It argues that the review's outcome was due to the imbalance of influence among EU member states and the diverging preferences of their Foreign Policy Executives (FPEs). These factors caused the Athena review to remain in the hands of a small group of member states that had diverging utility expectations and ideological preferences. Thus, the article shows that a surprisingly intense burden-sharing dispute has emerged within CSDP.
