This review of sociolinguistic aspects of language and dementia focuses on studies that (1) examine naturally occurring language with attention to variation that relates to speakers' cognitive or sociocultural attributes or to dimensions of the communicative context, (2) provide a nuanced understanding of individuals with dementia or contexts of communication that may illuminate sociolinguistic analyses, or (3) call for sociolinguistic investigations to clarify or provide additional evidence for a particular finding outside of linguistics. Structured from the global to the local levels, the review begins with literature that frames the study of language and dementia from the societal or cultural perspective, focusing on public discourse relating to dementia and Alzheimer's disease. Studies that shed light on social activities and physical environments are addressed next as possible influences on the shape of the discourse. Finally, investigations of verbal and nonverbal aspects of discourse produced by and with individuals with dementia are reviewed. Ideas for future research are outlined along with a call for increased cross-disciplinary cooperation among researchers who work at the intersection of language, dementia, and society.

Over half a century ago, psychologists hypothesized that social essentialism, an intuitive theory comprising the beliefs that social categories reflect naturally-occurring distinctions and that category members share an underlying and fundamental essence, lays the foundation for prejudice. In the intervening decades, research has shown that although essentialism sometimes leads to prejudicial beliefs, attitudes, and behaviors, it does not always, sometimes even leading to decreased prejudice toward stigmatized groups. The relation between essentialism and prejudice is clearly complex, but this review proposes four questions that will help clarify how and when essentialism leads to prejudice: (1) What precisely is essentialism and how might a more nuanced understanding of its components and structure shed light on the mechanisms by which essentialist beliefs contribute to prejudice?; (2) Do essentialist beliefs orient group-based prejudice toward out-groups or toward stigmatized groups, and what are the consequences of essentialist beliefs among those with minoritized identities?; (3) Do essentialist beliefs engender group-based prejudice directly, or must essentialist beliefs interact with additional information or belief systems to lead to negative consequences?; and (4) Do essentialist beliefs lay a foundation for group-based prejudice to develop, or is essentialism strategically invoked to justify existing prejudice? By posing these questions, describing what is currently known about each, and proposing future lines of inquiry that focus on the importance of including participants from a diverse set of backgrounds and across developmental periods, this review aims to stimulate research studies best designed to fill the gaps in our knowledge. By understanding how and when essentialism contributes to prejudice, we will be better equipped to use this early-emerging, but malleable, aspect of cognition to decrease prejudice and create a more equitable society.

Abstract Social engagement may confer cognitive benefits in older adulthood, but studies have typically been restricted to largely non-Hispanic White (NHW) samples. Levels of social engagement vary across race such that NHW report larger social networks, more frequent participation in social activities, and greater social support than non-Hispanic Blacks (NHB). Associations between social engagement and cognition may also vary by race, but research is sparse. The current cross-sectional study examined associations between different aspects of social engagement and episodic memory performance, as well as interactions between social engagement and race among NHB and NHW participants in the Michigan Cognitive Aging Project (N = 247; 48.4% NHB; age = 64.19 ± 2.92). Social engagement (network size, activities, support) was self-reported. Episodic memory was a z-score composite of immediate, delayed, and recognition trials of a list-learning task. Separate hierarchical linear regression models quantified interactions between race and each of the three social engagement variables on episodic memory, controlling for sociodemographics, depressive symptoms, and health conditions. Results showed a main effect of more frequent social activity on better episodic memory, as well as an interaction between race and social support indicating a significant positive association in NHB but not NHW. These preliminary findings suggest that participating in social activities may be equally beneficial for episodic memory across NHB and NHW older adults and that social support may be particularly beneficial for NHB. Future research is needed to determine the potential applications of these results in reducing cognitive inequalities through the development of culturally-relevant interventions.

Application of biomimetics has expanded progressively to other fields in recent years, including urban and architectural design, scaling up from materials to a larger scale. Besides its contribution to design and functionality through a long evolutionary process, the philosophy of biomimetics contributes to a sustainable society at the conceptual level. The aim of this review is to shed light on trends in the application of biomimetics to architectural and urban design, in order to identify potential issues and successes resulting from implementation. In the application of biomimetics to architectural design, parts of individual “organisms”, including their form and surface structure, are frequently mimicked, whereas in urban design, on a larger scale, biomimetics is applied to mimic whole ecosystems. The overall trends of the reviewed research indicate future research necessity in the field of on biomimetic application in architectural and urban design, including Biophilia and Material. As for the scale of the applications, the urban-scale research is limited and it is a promising research which can facilitate the social implementation of biomimetics. As for facilitating methods of applications, it is instrumental to utilize different types of knowledge, such as traditional knowledge, and providing scientific clarification of functions and systems based on reviews. Thus, interdisciplinary research is required additionally to reach such goals.

We report on the tendency of chaotic systems to be controlled onto their unstable periodic orbits in such a way that these orbits are stabilized. The resulting orbits are known as cupolets and collectively provide a rich source of qualitative information on the associated chaotic dynamical system. We show that pairs of interacting cupolets may be induced into a state of mutually sustained stabilization that requires no external intervention in order to be maintained and is thus considered bound or entangled. A number of properties of this sort of entanglement are discussed. For instance, should the interaction be disturbed, then the chaotic entanglement would be broken. Based on certain properties of chaotic systems and on examples which we present, there is further potential for chaotic entanglement to be naturally occurring. A discussion of this and of the implications of chaotic entanglement in future research investigations is also presented.

aaRSs (aminoacyl-tRNA synthetases) establish the rules of the genetic code by catalysing the formation of aminoacyl-tRNA. The quality control for aminoacylation is achieved by editing activity, which is usually carried out by a discrete editing domain. For LeuRS (leucyl-tRNA synthetase), the CP1 (connective peptide 1) domain is the editing domain responsible for hydrolysing mischarged tRNA. The CP1 domain is universally present in LeuRSs, except MmLeuRS (Mycoplasma mobile LeuRS). The substitute of CP1 in MmLeuRS is a nonapeptide (MmLinker). In the present study, we show that the MmLinker, which is critical for the aminoacylation activity of MmLeuRS, could confer remarkable tRNA-charging activity on the inactive CP1-deleted LeuRS from Escherichia coli (EcLeuRS) and Aquifex aeolicus (AaLeuRS). Furthermore, CP1 from EcLeuRS could functionally compensate for the MmLinker and endow MmLeuRS with post-transfer editing capability. These investigations provide a mechanistic framework for the modular construction of aaRSs and their co-ordination to achieve catalytic efficiency and fidelity. These results also show that the pre-transfer editing function of LeuRS originates from its conserved synthetic domain and shed light on future study of the mechanism.

The studies described in this article examine retrospective reports of naturally occurring misperceptions of friendliness as sexual interest. Previous research has demonstrated that men perceive other people and situations more sexually than women do. The purpose of this research was to examine how this gender difference in perceptions of sexuality is exhibited in actual interactions between women and men. Two surveys of undergraduates were conducted. The results indicated that a large percentage of both women and men had experienced such misperceptions, although more women had than men. Most of these incidents were quickly resolved without problems; however, others involved some degree of forced sexual activity and left the individual feeling angry, humiliated, and depressed. Gender differences in the characteristics of these incidents and reactions to them are described. The implications of these findings for future research on gender differences in perceptions of sexual intent are discussed.

Terrestrial environments have been suggested as an oxic haven for eukaryotic life and diversification during portions of the Proterozoic Eon when the ocean was dominantly anoxic. However, iron speciation and Fe/Al data from the ca. 1.1-billion-year-old Nonesuch Formation, deposited in a large lake and bearing a diverse assemblage of early eukaryotes, are interpreted to indicate persistently anoxic conditions. To shed light on these distinct hypotheses, we analyzed two drill cores spanning the transgression into the lake and its subsequent shallowing. While the proportion of highly reactive to total iron (FeHR/FeT) is consistent through the sediments and typically in the range taken to be equivocal between anoxic and oxic conditions, magnetic experiments and petrographic data reveal that iron exists in three distinct mineral assemblages resulting from an oxycline. In the deepest waters, reductive dissolution of iron oxides records an anoxic environment. However, the remainder of the sedimentary succession has iron oxide assemblages indicative of an oxygenated environment. At intermediate water depths, a mixed-phase facies with hematite and magnetite indicates low oxygen conditions. In the shallowest waters of the lake, nearly every iron oxide has been oxidized to its most oxidized form, hematite. Combining magnetics and textural analyses results in a more nuanced understanding of ambiguous geochemical signals and indicates that for much of its temporal duration, and throughout much of its water column, there was oxygen in the waters of Paleolake Nonesuch.

Although scholarship on competitive framing acknowledges that framing is a dynamic process in which the early stages may matter most, very little research has focused on the dynamics of issue emergence. In this article, we draw on several literatures to develop theories for how controversy related to new issues will emerge and expand in news coverage. Through a comprehensive content analysis of 101 local newspapers across the fifty U.S. states, we explore the dynamic and evolving process wherein a new issue—the HPV vaccine—emerged into public discourse and a legislative debate over school requirements for vaccination began. We find that coverage of controversy is a function of proximity, driven primarily by events within a state, although external events also influence local coverage. We also find that the legislative discussion in the media did not necessarily start out as controversial, but as the issue evolved, we observe a large increase in the proliferation of both actors taking positions and the types of arguments made to influence debate. The findings yield important insight into issue emergence with implications for how future research might test competing frames to better understand how the presentation of controversy in the mass media affects public opinion.

Social Media Communication

Urban public life has historically and famously been structured by social stratification and a segregation of social milieus. Such spatialized social inequality along the lines of, most importantly, class, age, and ethnicity engenders unequal access to civic participation and supportive social networks. Meanwhile, the Internet and Web 2.0 technologies in particular have often been hailed for their potential of bringing underrepresented voices into the public discourse and even creating so-called “networked counterpublics”, challenging social power structures. This contribution seeks to address the question of whether social media communication about urban issues challenges or reproduces patterns of spatial inequality in its attention distribution. Empirically, it investigates the distribution of place-naming within the Berlin-based Twitter discourse on housing. It finds that - while issue attention in the urban Twitter discourse is clearly spatially unequal, with a striking imbalance between center and periphery - neither sociodemographic composition nor issue characteristics perform well in explaining these patterns. Instead it proposes focusing more on local civic and activist infrastructure in future research.
