DNA-based and taxonomic identification of forensically important Sarcophagidae (Diptera) in southeastern Spain

Studying dipterans at the scene of a death can provide essential information for interpreting the evidence and help to reconstruct the events happened to a corpse in the past. Molecular tools have been employed for identification at specific levels in the cases of cryptic species or poorly conserved specimens. Identification of specimens is essential in forensic entomology since each species has a specific growth rate, which determines the calculation of the minimum post mortem interval (minPMI). In addition, phylogeographic reconstruction within a species can help to differentiate the haplotypes from a geographic area, thereby helping to clarify the possible relocation of a corpse. The morphological identification of Sarcophagidae species is often difficult, especially for the females. This is an important Diptera family since some of its species are among the first to reach a corpse, especially in warm areas. In this study, we compared the sarcophagids found in human corpses in forensic cases in Alicante (southeast of Spain) with specimens collected from baited traps in the same area and surrounding provinces. In total, 189 specimens were collected, comprising 72 from forensic cases and 117 from baited traps. Molecular identification was conducted by sequencing the cox1 mitochondrial gene and analyzing the sequences using ABGD, GMYC, and BIN species delimitation methods. The median joining algorithm in the PopART program was used to construct phylogeographic networks. Eight species in the family Sarcophagidae were identified. The most widely collected species were Sarcophaga argyrostoma and Sarcophaga tibialis. The haplotype networks obtained for these species did not indicate a clear geographic distribution of haplotypes. The S. argyrostoma samples from Alcoy were clearly isolated. The results demonstrated that this method is useful for identifying Sarcophagidae samples in forensic investigations and it can be employed for minPMI estimation.     

The trust “builders” in the technology transfer relationships: an Italian science park experience

This study proposes and assesses the effectiveness of a solution for disseminating trust in the technology transfer services. Focusing on the original experience of a science park located in Northern Italy, we propose a model focused on interface figures capable of conducting a direct dialogue with an enterprise and gaining its trust thanks to their reputation of reliability and expertise, the informal-personalised nature of the contact and their geographic, social, cultural and professional proximity. These factors stem from the features of this particular “boundary spanner” who identifies in the case-study with retired business owners/managers. This solution has proven to be particularly effective for small and medium-sized enterprises that typically show a preference for local and informal contacts within the networks and the need to refer to guide-figures when interacting with external knowledge sources because often they are not used to such scenarios.     

Challenger Quality and the Incumbency Advantage

Most estimates of the incumbency advantage and the electoral benefits of previous officeholding experience do not account for strategic entry by high‐quality challengers. We address this issue by using term limits as an instrument for challenger quality. Studying US state legislatures, we find strong evidence of strategic behavior by experienced challengers. However, we also find that such behavior does not appear to significantly bias the estimated effect of challenger experience or the estimated incumbency advantage. More tentatively, using our estimates, we find that 30–40% of the incumbency advantage in state legislative races is the result of “scaring off” experienced challengers.     

From the Language of Class to the Rhetoric of Development: discourses of ‘nationality’ and ‘ethnicity’ in China

In the People's Republic of China's (PRC) continuous state-building project since its establishment in 1949, the notion of nation and nationality (minzu) has been uninterruptedly utilised by the leading elite in its political programmes. The notion of the ‘nationality question’ (minzu wenti) was employed especially for addressing the issues of the officially identified minority nationalities at the time when the multinational nature of the state was made fundamental. However, how a multinational character of the Chinese state is interpreted by the state elite and how this interpretation is shaped by their policies have arguably changed along with the political and economic preferences of the regime. This paper aims to explore the meaning of ‘nationality question’ during the period of socialist construction, and traces the shift in its notion during the reform period which started in the 1970s. The essay pays attention to the change in the preferred corresponding English term of minzu wenti. I argue that the substitution of the ‘nationality question’ term, which was dominant during the socialist period, with the concept of the ‘ethnic question’ during the reform period points not only to the changing character of the government policies towards minorities, but also legitimises them as the only suitable and rightful in the context of economic reforms.     

Can Facebook really be a tool for supporting citizen engagement during emergencies?

The present study explores how Italian regions and their presidents employed Facebook during the Covid-19 pandemic to encourage citizen engagement. To do so, it adopts quantitative methodologies. Our results show that most public actors increased their levels of social activity during the pandemic but mainly for promoting public communication and that citizens much prefer interacting with presidents. Moreover, citizen engagement was higher when posts were published during nonbusiness hours or weekends, while it decreased when posts contained photos or videos.
