Delving into the images and technique that made the daguerreotype a cutting-edge technology in 1839, the author uses her access to Harvard's collection of images to explore the early phases of this format.

ABSTRACTSome liberal-cosmopolitan theorists have sought to justify preventive war by proposing new institutions meant to ensure the accurate evaluation of non-imminent threats, and also make any wa...

As new military technologies change the character of war by empowering agents in new ways, it can become more difficult for our ethics of war to achieve the right balance between moral principle and necessity. Indeed, there is an ever-growing literature that seeks to apply, defend and / or update the ethics of war in light of what is often claimed to be an unprecedented period of rapid advancement in military robotics, or warbots. To increase confidence that our approach to (...) this development finds success in appropriately constraining war, this article compares our current discourse to the ethical debate over the rise of air power during the interwar period. As moral norms largely failed to constrain air power in World War II, by highlighting the interrelated processes of technological change, ethical debate, and the eventual reconciliation of war practice and war ethics, this historical case offers insights that can help military ethicists maintain their “critical edge” as remote and autonomous robotic weapons continue to mature and proliferate.

Lewis et al. (2011) attempted to restore the reputation of Samuel George Morton, a 19th century physician who reported on the skull sizes of different folk-races. Whereas Gould (1978) claimed that Morton’s conclusions were invalid because they reflected unconscious bias, Lewis et al. alleged that Morton’s findings were, in fact, supported, and Gould’s analysis biased. We take strong exception to Lewis et al.’s thesis that Morton was “right.” We maintain that Gould was right to reject Morton’s analysis as inappropriate and (...) misleading, but wrong to believe that a more appropriate analysis was available. Lewis et al. fail to recognize that there is, given the dataset available, no appropriate way to answer any of the plausibly interesting questions about the “populations” in question (which in many cases are not populations in any biologically meaningful sense). We challenge the premise shared by both Gould and Lewis et al. that Morton’s confused data can be used to draw any meaningful conclusions. This, we argue, reveals the importance of properly focusing on the questions asked, rather than more narrowly on the data gathered. (shrink)

The Weather Prediction Task was originally designed to assess probabilistic classification learning. Participants were believed to gradually acquire implicit knowledge about cue–outcome association probabilities and solve the task using a multicue strategy based on the combination of all cue–outcome probabilities. However, the cognitive processes engaged in the resolution of this task have not been firmly established, and despite conflicting results, the WPT is still commonly used to assess striatal or procedural learning capacities in various populations. Here, we tested young adults (...) on a modified version of the WPT and performed novel analyses to decipher the learning strategies and cognitive processes that may support above chance performance. The majority of participants used a hierarchical strategy by assigning different weights to the different cues according to their level of predictability. They primarily based their responses on the presence or absence of highly predictive cues and considered less predictive cues secondarily. However, the influence of the less predictive cues was inconsistent with the use of a multicue strategy, since they did not affect choices when both highly predictive cues associated with opposite outcomes were present simultaneously. Our findings indicate that overall performance is inadequate to draw conclusions about the cognitive processes assessed by the WPT. Instead, detailed analyses of performance for the different patterns of cue–outcome associations are essential to determine the learning strategies used by participants to solve the task. (shrink)

Down syndrome (DS), the most common genetic cause of intellectual disability, results from the partial or complete triplication of chromosome 21. Individuals with DS are impaired at using a high-resolution, allocentric spatial representation to learn and remember discrete locations in a controlled environment. Here, we assessed the capacity of individuals with DS to perform low-resolution spatial learning, depending on two competing memory systems: (1) the place learning system, which depends on the hippocampus and creates flexible relational representations of the environment; (...) and (2) the response learning system, which depends on the striatum and creates fixed stimulus-response representations of behavioral actions. Individuals with DS exhibited a preservation of the low-resolution spatial learning capacities subserved by these two systems. In place learning, although the average performance of individuals with DS was lower than that of typically-developing (TD) mental age-matched children and TD young adults, the number of individuals with DS performing above chance level did not differ from TD children. In response learning, the average performance of individuals with DS was lower than that of TD adults, but it did not differ from that of TD children. Moreover, the number of individuals with DS performing above chance level did not differ from TD adults, and was higher than that of TD children. In sum, whereas low-resolution place learning appears relatively preserved in individuals with DS, response learning appears facilitated. Our findings are consistent with the hypothesis that the neural pathways supporting low-resolution place learning and response learning are relatively preserved in DS. (shrink)

Williams (WS) and Down (DS) syndromes are neurodevelopmental disorders with distinct genetic origins and different spatial memory profiles. In real-world spatial memory tasks, where spatial information derived from all sensory modalities is available, individuals with DS demonstrate low-resolution spatial learning capacities consistent with their mental age, whereas individuals with WS are severely impaired. However, because WS is associated with severe visuo-constructive processing deficits, it is unclear whether their impairment is due to abnormal visual processing or whether it reflects an inability (...) to build a cognitive map. Here, we tested whether blindfolded individuals with WS or DS, and typically developing (TD) children with similar mental ages, could use path integration to perform an egocentric homing task and return to a starting point. We then evaluated whether they could take shortcuts and navigate along never-traveled trajectories between four objects while blindfolded, thus demonstrating the ability to build a cognitive map. In the homing task, 96% of TD children, 84% of participants with DS and 44% of participants with WS were able to use path integration to return to their starting point consistently. In the cognitive mapping task, 64% of TD children and 74% of participants with DS were able to take shortcuts and use never-traveled trajectories, the hallmark of cognitive mapping ability. In contrast, only one of eighteen participants with WS demonstrated the ability to build a cognitive map. These findings are consistent with the view that hippocampus-dependent spatial learning is severely impacted in WS, whereas it is relatively preserved in DS. (shrink)

Health technology assessment consists of thesystematic study of the consequences of theintroduction or continued use of the technology in aparticular context, with the explicit objective toarrive at a judgment of the value or merit of thetechnology. Ideally, it is aimed at assessing allaspects of a given technology or group oftechnologies, including non-technical, e.g.socio-ethical, aspects. However, methods for assessingsocio-ethical implications of health technology arerelatively undeveloped and few mechanisms exist totake action based on the results of such evaluations.Still, the examples of cochlear (...) inplants and other cases illustratethat HTA is not a matter of merely collecting thefacts about a technology. The facts must beplausible and relevant from a particular framework,which is not always shared by different groups. It ishere that socio-ethical aspects are encountered. Ifhealth technology assessment aims to enhance theaccountability of the decision making processregarding funding and use of health technology, it isa major challenge to assessors of health technologiesto deal adequately with existing value pluralism. Inthis respect interactive evaluation may have somethingto offer. (shrink)

In "Democracy and Tradition," Jeffrey Stout contends that American constitutional democracy constitutes a well-functioning moral and political tradition that is not hostile to religion, although it does not depend on any specifically religious claims. I argue that Stout's contention is supported by a consideration of the great common law subject of contracts, as taught to first-year law students across the United States. First, I demonstrate how contract law can fruitfully be understood as a Maclntyrean tradition. Second, I illustrate the moral (...) richness of this tradition, and the mutually interpreting nature of rules and facts, by close attention to one particularly colorful case, Syester v. Banta. I conclude by suggesting that both religious and secular ethicists might find common law cases in general and contract law cases in particular to be a source of moral reflection that is substantively rich without being religiously divisive.

Introduksiyon -/- 50-50. Fifty-fifty. Sa bigkas ng mga Pinoy, “pipti-pipti.” Sa kontekstong Pilipino, pantukoy ito sa kalagayan ng taong nasa kritikal na kalagayan. Limampung porsyento ng tsansang makaligtas, limampung porsyento ng tsansang masawi. Kilala ito sa iba pang katawagan sa Pilipinas bilang “naghihingalo,” “nasa bingit ng kamatayan” o “nag-aagawbuhay.” Ganito mailalarawan ang kalagayan ng lipunang Pilipino sa ilalim ng Batas Militar ni Ferdinand Marcos, Sr. Para sa mga pabor sa Batas Militar at mga loyalista ni Marcos, 50-50 dahil sa (...) class='Hi'>banta raw ng komunismo at tangkang pagpapabagsak sa Republika. Para sa mga kritiko’t lumaban sa diktadura, 50- 50 dahil sa pang-aabuso’t paniniil ng rehimen laban sa taumbayan. 50-50. Ito ang sa tingin nami’y nababagay na pamagat ng aklat na ito. Una, ginugunita ng sambayanang Pilipino ngayong 2022 ang ika-50 taong anibersaryo ng Batas Militar. Idineklara ni Marcos noong Setyembre 21, 1972 ang Proclamation 1081 na naglagay sa buong bansa sa ilalim ng kamay na bakal. Pangalawa, itinatampok ng aklat ang 50 personalidad na may mga direkta at aktibong papel para o laban sa Batas Militar. Dalawampu’t lima (25) ang nagmula sa bakuran ng rehimeng Marcos. Bukod sa diktador at kanyang pamilya, sila ang mga pangunahing tagapagbalangkas at tagapagpatupad ng Batas Militar. Kasabwat sila sa kabuuang operasyon ng mga mekanismo ng awtoritaryanismong ito – mapapulitikal, ekonomiko o sosyokultural man. Sila rin ang mga nakinabang, kung hindi man nagpakasasa, sa lahat ng mga ganansyang dulot ng kolaborasyon at paglilingkod sa diktadura. Ang nalalabing 25 ay binubuo naman ng mga humamon at nanindigan laban sa kamay na bakal. Magkakaiba ang kanilang pinagmulan, mga adhikain at dulog sa pagtindig laban sa Batas Militar – armadong pakikibaka, pagkilos sa mga lansangan, paglaban mula sa pulpito, at iba pa. (shrink)
