Forensic examination of security features of the CDC-issued COVID-19 vaccination card and suggested improvements to minimize counterfeiting

During the COVID-19 pandemic, the United States released the CDC-issued vaccination card to document the status of immunizations. It eventually was used as a verification system to allow patrons to safely access public venues. This is/was apparently a simple printed piece of paper with minimal security features which made it an easy target for counterfeiters with little expertise required. Those unvaccinated who wished to enter areas that required proof of the COVID-19 vaccine were soon finding alternative illegal methods to do so which led to public health concerns. This research was divided into two parts. Part A aimed to forensically identify the security features with a video spectral comparator and a stereomicroscope. Ten “known” blank cards were collected directly from dispensaries that administered the vaccine and 68 “unknowns” from individuals who received the COVID-19 vaccine. Part B aimed to evaluate the authentication systems employed by countries outside the United States to propose a model on how the vaccination card could be improved and what security features should be included for future instances requiring proof of immunization. The results revealed the CDC document was produced with minimal security features making the document prone to counterfeiting. Furthermore, based on the information collected from other countries' vaccination certificates, it is recommended to develop a dual authentication system, with digital and printable aspects, that contains a QR code linked to a database. Other security features may include a non-optical brightener substrate, security fibers, a watermarked logo, offset printing, and a geographical color-coded system.     

New materials used for the synthesis of 2-chlorophenyl cyclopentyl ketone seized from an illicit ketamine manufacturing unit

Ketamine deemed as a psychoactive substance has gained popularity for recreational use owing to its hallucinogenic and dissociative effects. Understanding the synthetic processes of ketamine can provide essential clues for law enforcement officers against illicit ketamine manufacturing. In this case report, a chemical company was being monitored by law enforcement officers due to its importation of precursors and materials that could be used for the synthesis of illicit drugs. After materials and products seized from this chemical company were employed for analyses using gas chromatography–mass spectrometry, liquid chromatography–high-resolution mass spectrometry, and nuclear magnetic resonance analyses, ketamine, hydroxylamine, 2-chlorophenyl cyclopentyl ketone, and cyclopentanone p-toluenesulfonylhydrazone were identified. In addition, a novel process for the synthesis of ketamine precursor 2-chlorophenyl cyclopentyl ketone from cyclopentanone p-toluenesulfonylhydrazone and 2-chlorobenzaldehyde was validated. This is the first report to uncover this novel process for the synthesis of 2-chlorophenyl cyclopentyl ketone and can be used to increase awareness among law enforcement officers and forensic practitioners about these novel starting materials for the synthesis of ketamine.     

IPSASB’s Conceptual Framework: Coherence with Accounting Systems in European Public Administrations

Accounting and reporting systems in public administrations of European countries have deeply changed in the last 20 years due to the new public management wave and the trend toward international harmonization. This research aims to examine the possibility of implementing International Public Sector Accounting Standards Board’s (IPSASB’s) Conceptual Framework (CF), by observing accounting and reporting systems in the different governmental levels of countries selected and taking into account the embedded traditional characteristics of European countries. Results highlight how many structural differences still occur within and among countries, showing that much work is still necessary to obtain harmonization as implied in the IPSASB’s CF.

Upper‐Bounding the Incidence Rate of Associations Between Camouflage Uniforms and Surveillance Images*

Abstract: Camouflage garments can be associated with surveillance images of a crime scene even in the absence of unique wear marks or very high‐quality images. However, the probability of an accidental association, or incidence rate, is significant. The present work describes and validates a method for estimating the incidence rate based on a statistical model of the garment manufacturing process. The model was developed primarily for use with the current U.S. Army Combat Uniform (ACU), but can be applied to any camouflage garment. Eight garment manufacturers were studied, and all sources of variation in the manufacturing process were characterized. The marking and spreading procedures were found to be dominant and consistent sources of variation. However, some sources of variation, in particular those because of human operators, were not consistent enough to accurately characterize. Sources of variation that could not be well‐characterized were ignored in the statistical model, yielding a worst‐case estimate that is an upper‐bound to the true incidence rate. The model was evaluated for a variety of cases. Depending on the quality of the surveillance image, the manufacturing parameters, and the local population, incidence rates range from about 3% to negligibly small. The model was validated by returning to one manufacturer, and sampling a large number of completed garments and estimating empirical match probabilities. The empirical probabilities validated the estimates of the worst‐case incidence rate and also demonstrated that typical incidence rates are significantly lower.     

State marionettes,phantom organisations or genuine movements? The paradoxical emergence of rural social movements in post-socialist Russia

Of all the rural social movements in the world, those in post-socialist Russia have been considered to be among the weakest. Nevertheless, triggered by the neo-liberal reforms in the countryside, state attention to agriculture and rising land conflicts, new social movement organisations with a strong political orientation are emerging in Russia today. This sudden burst of civil activity, however, raises questions as to how genuine and independent the emerging organisations are. Our research shows that many rural movements, agricultural associations, farm unions and rural political parties lack constituency, support the status quo and/or are actually counterfeits (what we call ‘phantom movement organisations’). With this analysis, we aim to explain the nature of social movements in the post-Soviet countryside and offer an original contribution to the theory on and practice of rural social movements.     

The Cultural Aspects of Advertising Communications in Modern China

Advertising studies allow us not only to differentiate successful from unsuccessful marketing activities, but establish the fact as well that advertising reveals specific cultural norms that somehow differ depending on global regions. Advertising studies feature a clearly pronounced interdisciplinary nature and allow us to better understand what cultural basis specific advertising texts are made on. An advertising message is oriented on both rational and emotional-affective processes among the people perceiving the message. Modern Chinese consumers live in a complex social and cultural space. The ideology of the People’s Republic of China combines traditional philosophy, socialist ideas, and technological pragmatism. In modern China, advertising costs are skyrocketing (the year-to-year increase is about 100%). Chinese visual advertising images are based on a complex mixture of global and traditional cultural values and embody different aspects of “the Great Chinese Dream.” A visual analysis of Chinese advertisements allows us to see what traditional and global values are embodied by advertisers in advertising texts in order to render such advertising messages more effectively. Generally encountered are female images, nature-related images, and images pertaining to the ancient past of China. At the same time, ancient Chinese traditions are subject to globalization. Chinese traditional female images are created in the context of trends of mass culture. Nevertheless, the keynote remains within China’s traditional values. All the while, it features no forced separation from the global culture. It is more likely that China harmoniously includes the components considered acceptable within its own worldview.     

‘lay experts’: women's social purity groups and the politics of sexuality in Switzerland, 1890–1915

Women's social purity groups were significant participants in the debates of the regulation of sexualities during the unification process of Swiss Criminal Law between the 1890s and the 1930s. Although not yet enfranchised, women claimed political participation through their status as ‘lay experts’ with regard to sexual matters and as an interest group with backing from their male counterparts. The article examines their demands in the reformulation of the regulation of sexualities and investigates their aims and strategies. Their expertise, gained through the experience of and investment in ‘moral guardianship’, is examined here in relation to their interventions on the age of protection, or the age of consent in contemporary terms. As ‘lay experts’ on sexual morality, the women's social purity groups participated in the increased interests and discourses of sexuality between 1890 and 1915 in the midst of legal, medical and political experts.     

Visualization of latent fingerprints using fluorescence lifetime imaging on paper emitting strong fluorescence

Latent fingerprints were successfully visualized using fluorescence lifetime imaging (FLIM) on paper which emits strong fluorescence with a lifetime close to that of fingerprints and thus from which it is difficult for time-resolved spectroscopy to visualize fingerprints. Latent fingerprint samples on paper were excited using a 450 nm or 532 nm nanosecond pulsed-laser, and time-resolved fluorescence images were obtained at a delay time of 6–16 ns in intervals of 1 ns, to the excitation pulse. The excitation beam was expanded using a lens, and the fluorescence from the fingerprints was captured using an intensified CCD camera. Because of the large fluorescence intensity of the background paper of approximately two to four orders of magnitude larger than that of the fingerprint, the fingerprint was not visualized on each fluorescence image by time-resolved spectroscopy. However, the fingerprint was visualized in a FLIM image constructed using a series of the fluorescence images for the case with the fluorescence intensity of the background paper being four orders of magnitude larger than that of the fingerprint. The difference in fluorescence lifetime in the FLIM image of the visualized fingerprint and background paper was in the order of 0.1 ns, which was an order of magnitude smaller than the inherent fluorescence lifetime of a few nanoseconds for the fingerprints and paper. It was demonstrated that, at a background fluorescence intensity with a certain order of magnitude larger than that of fingerprints, FLIM has the potential to visualize latent fingerprints which cannot be visualized by time-resolved spectroscopy.
