We consider the problem of mixing in the f 0(980)–a 0(980) system when width effects are taken into account. By explicit calculation we show that two mixing angles are necessary to describe the phenomenon.
Background Community involvement in research has been advocated by researchers, communities, regulatory agencies, and funders with the aim of reinforcing subjects’ protection and improving research efficiency. Community involvement also has the potential to improve dissemination, uptake, and implementation of research findings. The fields of community based participatory research conducted with indigenous populations and of participatory action research offer a large base of experience in community involvement in research. Rules on involving the population affected when conducting research have been established in (...) these fields. But what is the role of community engagement in clinical research and observational studies conducted in biomedical research outside of these specific areas? Main body of the abstract More than 20 years ago, in the field of HIV medicine, regulatory bodies and funding agencies recommended the constitution of a formal organism, the Community Advisory Board, as part of the study requirements for HIV trials. More recently, CABs have been adopted and used in other fields of medical research, such as malaria. CABs are not without limitations, however, and there is little research on the effectiveness of their use in achieving community protection and participation. Nevertheless, CABs could be a model to import into clinical trials and observational research where no alternative model of community representation is currently being used. Conclusions Allocating more resources to training and shifting more power to community representatives could be part of the solution to current CAB limitations. However, for researchers to be able to apply these recommendations on community involvement, certain conditions need to be met. In particular, funding agencies need to recognize the human and financial resources required for serious community involvement, and the academic environment needs to take community involvement into account when appraising, mentoring, and training researchers.

Starting from the seminal experience of James Prescott Joule, this paper aims to debate the possibility of “making” science outside universities and academies. Joule himself studied as an autodidact and did not make his own discoveries while following an academic path; on the contrary, at first, the associations and academic societies of the time tended not to recognize his works officially. All of this happened throughout the nineteenth century during the period of the first relevant tendency to science popularization. For (...) example, looking at the second half of the England of the 1800s, we can refer to Michael Faraday’s open lessons for children like The Chemical History of a Candle. Following this perspective from a historical view, this paper explores the Italian attempts to communicate science—from the ‘50s to the ‘70s—to a larger public via television and other media, also considering the political and social backgrounds behind this choice. In particular, this paper also deals with Lucio Lombardo Radice’s work on TV programs and writings in social-political journals and daily newspapers, as a mathematician and pedagogist engaged on the importance of what he specifically called “Scientific mediation”, as a “method” to teach and popularize science to a larger public.

This paper aims to contribute to the present debate about business ethics and Corporate Social Responsibility (CSR) that the Journal of Business Ethics is hosting. Numerous contributions argued theoretical frameworks and taxonomies of CSR practices. The authors want to ground in this knowledge and provide further evidence about how companies adopt CSR practices to address stakeholders’ claims and consolidate their trust. Evidence was provided by a longitudinal case study about an Italian food company that is one of the largest producers (...) of baby food. This company reshaped its corporate strategy along three decades through the adoption of CSR practices in order to win stakeholders’ trust about food safety and supply chain behaviour. The empirical exercise was informed by a literature review of the relevant contributions in terms of CSR business practices and levels of efforts to adopt them. In light of this review, the authors adopted for the research framework the taxonomy of business practices proposed by Spiller (2000, “Ethical Business and Investment: A Model for Business and Society”, Journal of Business Ethics 27, 149-160) and the levels of commitment towards CSR proposed by Stahl and Grigsby (1997, Strategic Management; Total Quality & Global Competition (Blackwell, Oxford)). The main findings are discussed in order to argue theoretical implications and identify further areas of research and debate. (shrink)
The Autism Spectrum Disorder (ASD) represents a set of life-long disorders. In particular, subjects with ASD can display momentary behaviors of acute agitation and aggressiveness called crisis behaviors. These events are problematic for the subject and care providers but little is known about their occurrence, namely, possible relations among intensity, frequency, and duration. A group of ASD subjects (n=33) has been observed for 12 months reporting data on each crisis ( n = 1137 crises). Statistical analysis did not find significant (...) results, while the relation between crisis duration and frequency showed a good fit to a “power law” curve, suggesting the application of Self-Organized Criticality (SOC) model. The SOC is used to describe natural phenomena as earthquakes, bank failures of rivers, mass extinctions, and other systems where a type of “catastrophic events” is necessary to maintain a critical equilibrium. In a sense, subjects at risk of crisis behavior seem to fit the same model as seismic zones at risk of earthquakes. The employment of the same strategies, as those successfully developed for known SOC systems, could lead to important insights for ASD management. Moreover, the SOC model offers possible interpretations of crisis behavior dynamics suggesting that they are unpredictable and, in a sense, necessary. (shrink)
Living in the future, constantly thinking over it, incessantly inventing it, anticipating it, more than a Weltanschauung, a state of consciousness. It’s not about predicting rather living the prediction, experimenting with it, chasing the words to describe it, imagining the machines to produce it. The futurists’ undertaking was fueled by an overwhelming desire to overcome their present time through art and influence, by dint of its momentum, the society, culture and life that thrived around it, shifting their current world and (...) the one to come by virtue of an overflowing power of insights as well as an innovative and creative strength. This is what Futurism was, its constant, compelling self-supersession was its ontological matrix as this movement was projected and installed in a dimension of time that had severed both the past and the present. This study aims to frame this avant-garde on the basis of this chief cornerstone. (shrink)
