Appeals to need abound in everyday discussion. People make claims about their own needs all the time, and they do so in a way that suggests these should have a certain moral force. Needs also play an important role in contemporary popular discourse about social justice, climate change, obligations to future generations, dealing fairly with refugees, treating animals humanely, and critiques of consumerist lifestyles – to name just a few of the many examples. The idea of need is present in an increasing number of debates and domains. There is interest in need from several disciplines, not just philosophy, which also include psychology, economics, political science, social work and sociology. This volume, then, offers a fine introduction to an increasingly important concept in day-to-day life. In a new Foreword, Gillian Brock discusses the continuing significance of several innovative chapters in the book, indicating how they presaged new directions in philosophical conversation.
Through adopting a history-of-emotions framework, this article explores romantic love within Black enslaved communities of the antebellum and early postbellum South. Whilst several historians have already explored the emotion of love in enslaved emotional communities, there is a growing understanding by scholars of the history of emotions that emotions, including love, are not always adequately historicized, and have perhaps been taken at face or written value. In some contrast to previous historical scholarship, this article argues that the love, as expressed and experienced within Black enslaved communities, was complex, contentious, and far from monolithic.
Few studies have evaluated in-home teleneuropsychological (teleNP) assessment and none, to our knowledge, has evaluated the National Alzheimer’s Coordinating Center’s (NACC) Uniform Data Set version 3 tele-adapted test battery (UDS v3.0 t-cog). The current study evaluates the reliability of the in-home UDS v3.0 t-cog with a prior in-person UDS v3.0 evaluation.
One hundred and eighty-one cognitively unimpaired or cognitively impaired participants from a longitudinal study of memory and aging completed an in-person UDS v3.0 and a subsequent UDS v3.0 t-cog evaluation (∼16 months apart) administered either via video conference (n = 122) or telephone (n = 59).
We calculated intraclass correlation coefficients (ICCs) between each time point for the entire sample. ICCs ranged widely (0.01–0.79) but were generally indicative of “moderate” (i.e., ICCs ranging from 0.5–0.75) to “good” (i.e., ICCs ranging from 0.75–0.90) agreement. Comparable ICCs were evident when looking only at those with stable diagnoses. However, relatively stronger ICCs (Range: 0.35–0.87) were found between similarly timed in-person UDS v3.0 evaluations.
Our findings suggest that most tests on the UDS v3.0 t-cog battery may serve as a viable alternative to its in-person counterpart, though reliability may be attenuated relative to the traditional in-person format. More tightly controlled studies are needed to better establish the reliability of these measures.
The coronavirus disease 2019 (COVID-19) pandemic has resulted in shortages of personal protective equipment (PPE), underscoring the urgent need for simple, efficient, and inexpensive methods to decontaminate masks and respirators exposed to severe acute respiratory coronavirus virus 2 (SARS-CoV-2). We hypothesized that methylene blue (MB) photochemical treatment, which has various clinical applications, could decontaminate PPE contaminated with coronavirus.
The 2 arms of the study included (1) PPE inoculation with coronaviruses followed by MB with light (MBL) decontamination treatment and (2) PPE treatment with MBL for 5 cycles of decontamination to determine maintenance of PPE performance.
MBL treatment was used to inactivate coronaviruses on 3 N95 filtering facepiece respirator (FFR) and 2 medical mask models. We inoculated FFR and medical mask materials with 3 coronaviruses, including SARS-CoV-2, and we treated them with 10 µM MB and exposed them to 50,000 lux of white light or 12,500 lux of red light for 30 minutes. In parallel, integrity was assessed after 5 cycles of decontamination using multiple US and international test methods, and the process was compared with the FDA-authorized vaporized hydrogen peroxide plus ozone (VHP+O3) decontamination method.
Overall, MBL robustly and consistently inactivated all 3 coronaviruses with 99.8% to >99.9% virus inactivation across all FFRs and medical masks tested. FFR and medical mask integrity was maintained after 5 cycles of MBL treatment, whereas 1 FFR model failed after 5 cycles of VHP+O3.
MBL treatment decontaminated respirators and masks by inactivating 3 tested coronaviruses without compromising integrity through 5 cycles of decontamination. MBL decontamination is effective, is low cost, and does not require specialized equipment, making it applicable in low- to high-resource settings.
The study of culture is usually the preserve of social anthropologists, sociologists and cultural theorists who have developed sophisticated theories to describe and explain cultural phenomena. Recently, there has been much interest in an evolutionary approach to culture. In contrast to many earlier theories these evolutionary theories attempt to provide ultimate rather than proximate explanations of culture. One of the biggest ultimate questions about culture is why do we have culture at all? From this perspective, the phenomenon of culture is not something that ‘just happened’; there is good evidence that human culture needs a particular sort of brain in order to sustain it.

Without language, social interaction would be impoverished beyond recognition. It enables us to reveal our innermost thoughts to others, or, if the mood takes us, to disguise them with misinformation and lies. With language, action can be coordinated so that a group of people can act as one – even if chimpanzees could conceive of a pyramid they still couldn’t build one because they lack the ability to coordinate action through language. Language also, as we shall see in Chapter 14, enables hard-won knowledge to be passed on to others – including our children – enabling culture to proliferate in ways that would not have been possible in our languageless ancestors (in fact, as we shall see, one theory proposes that language evolve to facilitate cultural transmission). When language evolved it was evolutionary dynamite. Not only did it vastly extend the range of things that ancestral humans were capable of, enabling them, perhaps, to outcompete other hominins around at the time, but it is also likely to have had an impact on the evolution of the brain itself. It is unlikely that our languageless ancestors had brains identical to ours but lacking the appropriate language circuitry; it is more likely that the gradual evolution of communicative sophistication led to huge leaps in the way that we interact with others. So great are the advantages of language to our species that surely it must have been the product of natural (or sexual) selection.
