Human noroviruses (hNoVs) are the most important foodborne viruses, and soft berries are one of the most common food sources of hNoV outbreaks and contamination. This paper presents a human volunteer study in order to investigate the correlation between molecular detection results of hNoV in berries with the public health risks. The participants with diverse histo-blood group antigens (HBGAs) phenotypes were required to consume self-purchased berries and meanwhile submit aliquots of the products for reverse transcription-quantitative polymerase chain reaction (RT-qPCR) detection. As a result, none of the 20 participants reported any hNoV infection-like symptoms after six independent consumptions (120 consumptions in total). In contrast, within the 68 berry samples with >1% virus recoveries, 28 samples were detected to be positive for hNoV GI and/or GII (the positive rate at 41%). All of the positive signals were below the limit of quantification (<120 genome copies/g) except one fresh strawberry sample at 252 genome copies/g. It is expected that this study would contribute to the definition of quantitative standards for risk assessment purposes in the future.

ABSTRACT Prevailing definitions of protein quality are predicated on considerations of biochemistry and metabolism rather than the net effects on human health or the environment of specific food sources of protein. In the vernacular, higher “quality” equates to desirability. This implication is compounded by sequential, societal trends in which first dietary fat and then dietary carbohydrate were vilified during recent decades, leaving dietary protein under an implied halo. The popular concept that protein is “good” and that the more the better, coupled with a protein quality definition that favors meat, fosters the impression that eating more meat, as well as eggs and dairy, is desirable and preferable. This message, however, is directly opposed to current Dietary Guidelines for Americans, which encourage consumption of more plant foods and less meat, and at odds with the literature on the environmental impacts of foods, from carbon emissions to water utilization, which decisively favor plant protein sources. Thus, the message conveyed by the current definitions of protein quality is at odds with imperatives of public and planetary health alike. We review the relevant literature in this context and make the case that the definition of protein quality is both misleading and antiquated. We propose a modernized definition that incorporates the quality of health and environmental outcomes associated with specific food sources of protein. We demonstrate how such an approach can be adapted into a metric and applied to the food supply.

Abstract Amblyomma maculatum Koch is the primary vector of Rickettsia parkeri, the etiologic agent of tidewater spotted fever, and can also carry and transmit a variety of other pathogens. This tick historically has been a costly nuisance to livestock owners in the southeastern United States. Over the past 6 yr, A. maculatum has been collected in numbers sufficient to demonstrate their establishment in Kent County, Delaware, and the presence of R. parkeri has been documented. Our goals were to determine the geographic distribution of A. maculatum and R. parkeri in Delaware, and to equate this to relative risk to the public of encountering R. parkeri-infected ticks. We surveyed for ticks in four locations throughout the state from May to August 2019, and found established A. maculatum populations in all three counties. Laboratory analysis of collected specimens by quantitative polymerase chain reaction detected R. parkeri in A. maculatum populations across the state. These results indicate that A. maculatum could present a health risk to inhabitants of the state, and they also historically have posed a risk to the livestock industry, making them an important consideration in the development and implementation of continued tick surveillance efforts and future policies regarding tick management.

Abstract To establish a rapid method for the simultaneous differential detection of porcine circovirus types 2 (PCV2) and 3 (PCV3), two pairs of primers and two TaqMan probes were designed according to the gene sequences of PCV2 and PCV3, and a dual TaqMan fluorescence quantitative polymerase chain reaction (PCR) method for the simultaneous detection of two virus nucleic acids was established. The results showed that the correlation coefficients (R2) of the standard curves drawn using the recombinant plasmids of PCV2 and PCV3 were greater than 0.99 and had a good linear relationship. The specific detection results of PCV type 1, Porcine parvovirus, and Porcine pseudorabies virus were negative. The detection limits of this experimental method for PCV2 and PCV3 were 10 and 1 copies/μL, respectively, which were more sensitive than those of the common PCR detection methods. The established method was used to detect 76 samples from some pig farms in Shandong Province. 11 of the 76 samples were PCV3 positive (positive rate of 14.47%), 24 were PCV2 positive (positive rate of 34.58%), and PCV3 and PCV2 were mixed in six samples (positive rate of 7.89%). The whole-genome sequence of PCV3 was amplified and sequenced to further understand the molecular biological characteristics and genetic variation of PCV3 in Shandong Province. The genomes of 11 PCV3 strains were all 2000 bp long, and the whole-genome sequence homology between them ranged from 98.4% to 99.9%. There were mutation sites in the amino acid sequences of Cap and Rep proteins, and the strains isolated in this experiment were concentrated in the PCV3a and PCV3c subgroups. This study provides technical support and molecular biological basis for nucleic acid detection, epidemiological characteristics, genetic variation, and control of PCV3 in Shandong Province.

The European Commission initiated a discussion on the expediency of using the International Public Sector Accounting Standards (IPSAS), based on the IAS/IFRS, as a common base for harmonizing the public sector accounting systems of the member states. However, literature suggests that accounting is not neutral with respect to the economic, social and political dimensions. In the perspective of evolution of the accounting regulation outlined, balanced between accountability, with the need to represent phenomena for reporting pur-poses, and decisionmaking issues, which concentrates on the quantitative importance of the values, the paper aims to analyse the effects of the application of different criteria for the definition of the reporting entity of the local government consolidated financial statements (CFS). The Italian PCA 4/4, the test of control and the financial accountability approaches are examined. The evidence that emerged from the case studies examined identifies several criticalities in the Italian PCA 4/4 and support the thesis that the financial accountability approach is more effective in providing a complete representation of the public resources entrusted to and managed by the group, whereas the control approach better approximates quantification of the group results in terms of central government surveillance. The analysis highlights the importance of the post implementation review period and the opportunity to contextualize the adoption of the consolidated financial statement in the broader spectrum of the accounting harmonization process, participating in the process of definition of the European Public Sector Accounting Standards (EPSAS).

Excessive presence of polysaccharides, polyphenol and secondary metabolites in banana plant affects the quality of DNA and it leads to difficult in isolating good quality of DNA. An optimized modified CTAB protocol for the isolation of high quality and quantity of DNA obtained from banana leaf tissues has been developed. In this protocol a slight increased salt (NaCl) concentration (2.0M) was used in the extraction buffer. Polyvinylpyrrolidone (PVP) and Octanol were used for the removal of polyphenols and polymerase chain reaction (PCR) inhibitors. Proteins like various enzymes were degraded by Proteinase K and removed by centrifugation from plant extract during the isolation process resulting in pure genomic DNA, ready to use in downstream applications including PCR, quantitative polymerase chain reaction (qPCR), ligation, restriction and sequencing. This protocol yielded a high molecular weight DNA isolated from polyphenols rich leaves of Musa spp which was free from contamination and colour. The average yields of total DNA from leaf ranged from 917.4 to 1860.9 ng/ìL. This modified CTAB protocol reported here is less time consuming 4-5h, reproducible and can be used for a broad spectrum of plant species which have polyphenol and polysaccharide compounds.

Drawing on Karin Bijsterveld’s triple definition of noise as ownership, political responsibility, and causal responsibility, this article traces how modern Japan problematized noise, and how noise represented both the aspirational discourse of Western civilization and the experiential nuisance accompanying rapid changes in living conditions in 1920s Japan. Primarily based on newspaper archives, the analysis will approach the problematic of noise as it was manifested in different ways in the public and private realms. In the public realm, the mid-1920s marked a turning point due to the reconstruction work after the Great Kantô Earthquake (1923) and the spread of the use of radios, phonographs, and loudspeakers. Within a few years, public opinion against noise had been formed by a coalition of journalists, police, the judiciary, engineers, academics, and municipal officials. This section will also address the legal regulation of noise and its failure; because public opinion was “owned” by middle-class (sub)urbanites, factory noises in downtown areas were hardly included in noise abatement discourse. Around 1930, the sounds of radios became a social problem, but the police and the courts hesitated to intervene in a “private” conflict, partly because they valued radio as a tool for encouraging nationalist mobilization and transmitting announcements from above. In sum, this article investigates the diverse contexts in which noise was perceived and interpreted as such, as noise became an integral part of modern life in early 20th-century Japan.

"Feminist Interpretations of Action and the Public in Hannah Arendt’s Theory. Arendt’s typology of human activity and her arguments on the precondition of politics allow for a variety in interpretations for contemporary political thought. The feminist reception of Arendt’s work ranges from critical to conciliatory readings that attempt to find the points in which Arendt’s theory might inspire a feminist political project. In this paper I explore the ways in which feminist thought has responded to Arendt’s definition of action, freedom and politics, and whether her theoretical framework can be useful in a feminist rethinking of politics, power and the public realm. Keywords: Hannah Arendt, political action, the Public, the Social, feminism "

Over the past several years, transplantology has become one of the fastest developing areas of medicine. The reason is, first and foremost, a significant improvement of the results of successful transplants. However, much controversy arouse among the public, on both medical and ethical grounds. The article presents the most important concepts and regulations relating to the collection and transplantation of organs and tissues in the context of the European Convention on Bioethics. It analyses the convention and its additional protocol. The article provides the definition of transplantation and distinguishes its types, taking into account the medical criteria for organ transplants. Moreover, authors explained the issue of organ donation ex vivo and ex mortuo. The European Convention on Human Rights and Biomedicine clearly regulates the legal aspects concerning the transplantation and related basic concepts, and therefore provides a reliable source of information about organ transplantation and tissue. This act is a part of the international legal order, which includes the established codification of bioethical standards.

The article is devoted to issues of ensuring transparency and ac- countability of authorities in the conditions of participatory democracy (democ- racy of participation). It is argued that the public should be guaranteed not only the right for access to information but also the prerequisites for expanding its par- ticipation in state governance. These prerequisites include: the adoption of clearly measurable macroeconomic and social goals and the provision of control of the processes of their compliance with the government by citizens of the country; ex- tension of the circle of subjects of legislative initiative due to realization of such rights by citizens and their groups; legislative definition of the forms of citizens’ participation in making publicly significant decisions, design of relevant orders and procedures, in particular participation in local referendum; outlining methods and procedures for taking into account social thought when making socially im- portant decisions. The need to disclose information about resources that are used by authorities to realize the goals is proved as well as key performance indicators that can be monitored by every citizen; the efforts made by governments of coun- tries to achieve these goals. It was noted that transparency in the conditions of representative democracy in its worst forms in a society where ignorance of the thought of society and its individual members is ignored does not in fact fulfill its main task — to establish an effective dialogue between the authorities and so- ciety. There is a distortion of the essence of transparency: instead of being heard, society is being asked to be informed — and passively accept the facts presented as due. In fact, transparency and accountability in this case are not instruments for the achievement of democracy in public administration, but by the form of a tacit agreement between the subjects of power and people, where the latter passes the participation of an “informed observer”.

The article is devoted to the research of goals and functions of lobbying activity. The author has processed the ideas of domestic and foreign scientists, proposed his own approaches to the definition of goals and functions of lobbying activities through the prism of public administration. As a result, a generalized vision of the goals and functions of lobbying activities as interrelated elements of the lobbying system was proposed, and a forecast for further evolution of the goals and functions of domestic lobbying was provided. The analysis of lobbying functions allowed us to notice the tendencies in shifting the goals of this activity. If the objectives were fully covered by functions such as mediation between citizens and the state, the information function and the function of organizing plurality of public interests, then the role of strengthening the self-organization of civil society and the function of compromise become increasingly important in the process of formation in the developed countries of civil society and the development of telecommunication technologies. Ukrainian lobbyism will not be left to the side of this process. Already, politicians of the highest level, leaders of financial and industrial groups have to act, adjust their goals (even if they are — declared), taking into account the reaction of the public. In the future, this trend will only increase. The analysis of current research and political events provides all grounds for believing that, while proper regulatory legislation is being formed in Ukraine, the goals and functions of domestic lobbying will essentially shift towards a compromise with the public. It is noted that in spite of the existence of a basic direction of action, lobbying may have several ramified goals. Guided by the goals set, lobbyism can manifest itself in various spheres of the political system of society, combining the closely intertwined interests of various actors in the lobbying process, or even — contrasting them.
