This paper is concerned with a natural deduction system for First Degree Entailment (FDE). First, we exhibit a brief history of FDE and of combined systems whose underlying idea is used in developing the natural deduction system. Then, after presenting the language and a semantics of FDE, we develop a natural deduction system for FDE. We then prove soundness and completeness of the system with respect to the semantics. The system neatly represents the four-valued semantics for FDE.

Nanotechnology presents significant challenges in terms of developing a regulatory framework. This is due to a lack of scientific knowledge about the behaviour of the technology in its interactions with biological and ecological processes, the environment and other technologies. Crucially, there is a great deal of uncertainty surrounding the potential environmental and human health and safety impacts of NT. Consequently, the development of NT is a potential test case for framing new models of ‘soft law’ voluntary governance as a substitute (...) for traditional command and control type regulation. Driven by ‘new science governance,’ an approach based on a combination of ideas in anticipatory ethics, future-oriented responsibility, upstream public engagement and deliberation and theories of justice may offer a solution. The uniqueness of the approach can be found in the incorporation of anticipatory approaches via public participation and deliberation as the input into procedural justice approaches with distributional justice as the output. The overarching objective of this work is to contribute to the discussion in relation to the internalisation of responsibility and the building of intellectual and societal capacity to anticipate negative consequences before they arise in the hope that such an approach could be the antithesis of the retrospective imposition of responsibility and liability after the harm is done, which is the outcome of traditional regulatory and ethical approaches. Ultimately, the purpose is to contribute to the long-term sustainability of NT. (shrink)

Lagos-based Raypower Radio is one of the very few stations in Nigeria that is offering broadcasts in Nigerian local languages and tribal dialects. Due to the pre-dominant use of English in the education system native Nigerian languages tend to be considered as inferior, especially among social circles of higher education and wealthy background. This research attempts to analyse the influence of parental attitude towards tribal dialects as a barrier or motivational source for Nigerian youth in terms of the use and (...) acquisition of local languages and the reception of radio stations offering local content.

There has been much discussion about what, if any, legal and moral duties professionals have to disclose relevant genetic information to the family members of someone with an identified disease predisposing mutation. Here, we present a case report where dissemination of such a genetic test result did not take place within a family. In contrast to previous literature, there appeared to be no deliberate withholding of information, instead distant relatives were unable to communicate relevant information appropriately. When communication was facilitated (...) through the follow-up of a chance remark, the patient was able to avoid planned major surgery, with its attendant morbidity, and her high anxiety levels were much reduced. We believe this case highlights the need for an ongoing debate on how genetic services can best support patients and their families with disclosing relevant genetic information to other family members.

Background This article describes the issues encountered when designing a study to evaluate recruitment of minority ethnic groups into clinical cancer research in order to monitor adherence to the principles for good practice set out in the Department of Health, Research Governance Framework, England. Methods (i) A review of routine data sources to determine whether their usefulness as a source of data on prevalence of cancer in the population by ethnic category. (ii) A local case study at one hospital trust (...) to ascertain whether the ethnicity of cancer trial participants was representative of admitted cancer patients. Results (i) The lack of a comparator population makes it problematic to assess recruitment levels by ethnic group in clinical research. (ii) The odds of being in a trial were 30% lower for a member of a minority ethnic group compared to a white cancer patient after adjusting for disease, age and gender, OR 0.70 (0.53 to 0.94). These results differed for each ethnic group; Asian patients did not appear under-represented while Black and Chinese did so. However, there are important caveats to the findings based on the limited recording of ethnicity. Conclusions The lack of available data on the ethnicity of participants in clinical research and the prevalence of cancer in the population according to ethnicity makes it difficult to design a study to monitor representation of minority ethnic groups. This information is necessary to assess adherence to the Research Governance Framework principle that research evidence reflects the diversity of the population. (shrink)

Near the beginning of In Toga Candida, Cicero informed his audience of a private meeting between his two most serious competitors for the consulate and the managers of their campaigning funds. This meeting took place at the house of a nobleman whom Cicero did not name but to whom he attributed a signal notoriety in the practice of electoral corruption. Asconius offers a solution without hesitation: it was at the house of either Caesar or Crassus. He explains his choice: these (...) two men were Cicero's most committed and influential opponents in his campaign for the consulate, and he has excellent evidence for their opposition: Cicero's own Expositio consiliorum suorum, no longer extant. The credibility or otherwise of this controversial work must be dismissed from any enquiry into the identity of the mysterious figure, however. Asconius, in naming the two alternative possibilities, discloses himself to be without authoritative evidence on the point. Nothing can have been said in De consiliis suis to identify the house, the meeting, or the notorious nobleman. Asconius' words reveal that his attempt at an identification is based on Cicero's assertion therein of an overt hostility to him on the part of both Crassus and Caesar during the campaign. His attribution of a covert ‘dirty tricks’ operation to one of them is no more than speculation. (shrink)

The uniqueness of the teaching profession is revealed in the article, a teacher professiogram is given and the content of such basic scientific concepts such as educational activities, pedagogical culture, pedagogical competence is specified. The content of the article is related to the change of the educational paradigm, which assumes an orientation on the work of teachers. The mission of the teacher is defined as the creation of the individual, the assertion of man in a man. Drawing on theoretical sources, (...) a portrait of a modern teacher personality is created. The article also focuses on the concept of professional self-development, indicating internal and external sources of self-development activity. To deploy the processes of self-development is of great importance level of development of self-esteem. The author reveals the methods of formation of true self-esteem necessary to form in one's mind the image of the ideal teacher. (shrink)
