Staging Science: Authoritativeness and Fragility of Models and Measurement in the COVID-19 Crisis

In the COVID-19 crisis, society pins its hopes on science to play an authoritative role in reducing uncertainty and ambiguity. But is science up to the task? This is far from self-evident. The demands on science in times of crisis run counter to the values of good, normal science. Crisis science needs to be fast, univocal, personalized, and direct, while normal science is slow, contentious, collective, and sensitive to complexity. Science can only play its atypical role if it is staged in the public arena. Some patterns of staging stand out: personalization, visualization, and connection to lived experiences. So far, the staging of science has been successful, but it is fragile. The COVID-19 crisis shows the potential of well-staged forms of alliance between science and policy, but when the general assumption is that scientists will “solve” societal “problems,” the staging of science has gone too far.     

Does Stimulating Physical Activity Affect School Performance?

This paper investigates whether encouraging children to become more physically active in their everyday life affects their primary school performance. We use data from a field quasi-experiment called the Active Living Program, which aimed to increase active modes of transportation to school and active play among 8- to 12-year-olds living in low socioeconomic status (SES) areas in the Netherlands. Difference-in-differences estimations reveal that while the interventions increase time spent on physical activity during school hours, they negatively affect school performance, especially among the worst-performing students. Further analyses reveal that increased restlessness during instruction time is a potential mechanism for this negative effect. Our results suggest that the commonly found positive effects of exercising or participating in sports on educational outcomes may not be generalizable to physical activity in everyday life. Policymakers and educators who seek to increase physical activity in everyday life need to weigh the health and well-being benefits against the probability of increasing inequality in school performance.     

The Role of Interface on the Impact Characteristics and Cranial Fracture Patterns Using the Immature Porcine Head Model

The role of impact interface characteristics on the biomechanics and patterns of cranial fracture has not been investigated in detail, and especially for the pediatric head. In this study, infant porcine skulls aged 2–19 days were dropped with an energy to cause fracturing onto four surfaces varying in stiffness from a rigid plate to one covered with plush carpeting. Results showed that heads dropped onto the rigid surface produced more extensive cranial fracturing than onto carpeted surfaces. Contact forces generated at fracture initiation and the overall maximum contact forces were generally lower for the rigid than carpeted impacts. While the degree of cranial fracturing from impacts onto the heavy carpeted surface was comparable to that of lower‐energy rigid surface impacts, there were fewer diastatic fractures. This suggests that characteristics of the cranial fracture patterns may be used to differentiate energy level from impact interface in pediatric forensic cases.     

Healed Depressed Parasagittal Skull Fractures—A Feature of Archaic Australian Aboriginal Remains

The skeletal remains of eight Australian Aboriginals with healed depressed skull fractures were examined. Male:female ratio 5:3; age range 20‐60 yrs. Burial dates by ¹⁴C dating in three cases were 500 years BP (n = 2) and 1300 BP. There were 13 healed depressed skull fractures manifested by shallow indentations of cortical bone and thinning of diploe, with no significant disturbance of the inner skull tables. Nine (69%) were located within 35 mm of the sagittal suture/midline. These lesions represent another acquired feature that might be helpful in suggesting that a skull is from a tribal Aboriginal individual and may be particularly useful if the remains are represented by only fragments of calvarium. While obviously not a finding specific to this population, these healed injuries would be consistent with the possible results of certain types of conflict behavior reported in traditional Aboriginal groups that involved formalized inflicted blunt head trauma.     

Re-visiting Mr. Nice. On organized crime as conversational interaction

Studies of organized crime often seem to have focus almost exclusively on its functionality and rationality. Many researchers tend to construct organized crime as an object, and then to find relations between ‘it’ and its environment. The focus then is on organized crime as a goal-driven object. This view holds that success in crime depends on the roles and tasks people assume. It equates success in crime with functional secrecy and obedience, and therefore with stability. Researchers are seldom interested in everyday, informal elements and events such as coincidental encounters that may occur in everyday life, or personal relationships which have no direct connection with criminal activities. Inspired by the work of Watts and Strogatz [84] and Stuart Kauffman [38, 39], this paper attempts to suggest a complementary perspective on organized crime. The focus here is on the messiness and unpredictability of everyday relations and interactions. This paper illustrates the usefulness of this alternative perspective through a re-reading of Howard Marks’ ego-document which was analysed earlier by Carlo Morselli in his work on network dynamics and criminal career opportunities.     

Reconciliation between Korea and Japan

Although Japan and Korea formally normalized their relationsin 1965, these neighbours remain wary of each other becauseof their awkward history during the first half of the twentiethcentury, when Japan annexed Korea and oppressed the Koreansin many ways. Korean scholars believe strongly that this annexationwas "illegal" and that it constituted a violation of internationallaw when it occurred. Japanese scholars tend to admit that theJapanese occupation of Korea was brutal and caused enormoussuffering, but they are reluctant to acknowledge that the annexationwas "illegal", because other great powers were annexing smallcountries during that period. The US action supporting the overthrowof the Kingdom of Hawaii in 1893 and annexing Hawaii in 1898may be helpful in finding an appropriate resolution to the Japan–Koreastandoff. In 1993, the US Congress enacted a joint resolutionformally apologizing to the Native Hawaiian people and callingfor a "reconciliation" between the United States and the NativeHawaiians. This resolution acknowledged that the US diplomaticand military support for the 1893 overthrow was "illegal" andwas in violation of "international law". This strong statementseems to be an application of "intertemporal law", whereby presentviews of international law are applied to the events of the1890s, but, in any event, it is a powerful acknowledgment thata wrong occurred, causing injuries that can still be felt today.The reconciliation process between the United States and NativeHawaiians is now under way and, to be complete, it will requirethe restoration of the sovereignty of the Native Hawaiians anda return of land and resources to them. Japanese officials haveoffered apologies to the Koreans, but the reconciliation betweenthe two countries can become complete only if these apologiesare accompanied by a transfer of items of real value. This paperproposes that proper payments to the Korean comfort women anda renunciation by Japan of its claim to Dokdo/Takeshima (thetiny islands claimed by both countries) could serve to formalizethe reconciliation between these two neighbours.     

Recovery of human remains after shark attack

Two cases of fatal shark attack are reported where the only tissues recovered were fragments of lung. Case 1: An 18-year-old male who was in the sea behind a boat was observed by friends to be taken by a great white shark (Carcharodon carcharias). The shark dragged him under the water and then, with a second shark, dismembered the body. Witnesses noted a large amount of blood and unrecognizable body parts coming to the surface. The only tissues recovered despite an intensive beach and sea search were 2 fragments of lung. Case 2: A 19-year-old male was attacked by a great white shark while diving. A witness saw the shark swim away with the victim's body in its mouth. Again, despite intensive beach and sea searches, the only tissue recovered was a single piece of lung, along with pieces of wetsuit and diving equipment. These cases indicate that the only tissue to escape being consumed or lost in fatal shark attacks, where there is a significant attack with dismemberment and disruption of the integrity of the body, may be lung. The buoyancy of aerated pulmonary tissue ensures that it rises quickly to the surface, where it may be recovered by searchers soon after the attack. Aeration of the lung would be in keeping with death from trauma rather than from drowning and may be a useful marker in unwitnessed deaths to separate ante- from postmortem injury, using only relatively small amounts of tissues. Early organ recovery enhances the identification of human tissues as the extent of morphologic alterations by putrefactive processes and sea scavengers will have been minimized. DNA testing is also possible on such recovered fragments, enabling confirmation of the identity of the victim.     

Differentiating writing inks using direct analysis in real time mass spectrometry

Writing ink analysis is used in establishing document authenticity and the sources and relative ages of written entries. Most analytical methods require removing samples or visibly altering the document. Nondestructive, in situ analysis of writing inks on paper without visible alteration is possible using mass spectrometry with a new ion source called Direct Analysis in Real Time. Forty-three different black and blue ballpoint, black fluid, and black gel inks were examined. Both dyes and persistent but thermally labile components of the inks contribute to the mass spectra, principally as protonated molecules [M+H](+). Numerous ink components were identified from the spectra. The spectra were placed in a searchable library, which was then challenged with two spectra from each of the 43 inks. The best match for each of the challenge spectra was correct for all but one ink, which matched with a very similar ink by the same manufacturer.
