The “legacy effect” of lynchings and other forms of racialized violence has shaped patterns of inequality in America. While past studies have been relatively similar in their design—relating basic counts of lynchings to various contemporary outcomes—I argue for and demonstrate a more nuanced approach. I show that if we think of racialized violence as more than just the act of lynching, and consider both the temporal and spatial proximity between historic events of racial violence and contemporary inequality, we can establish this relationship in a more fulsome way. In the case of this study, the relationship is drawn to housing segregation. I argue that expanding the conceptualization of racial violence is critical for both empirical inquiry and shaping community efforts around redress.

An important goal of software development in the medical field is the design of methods which are able to integrate information obtained from various imaging and nonimaging modalities into a cohesive framework in order to understand the results of qualitatively different measurements in a larger context. Moreover, it is essential to assess the various features of the data quantitatively so that relationships in anatomical and functional domains between complementing modalities can be expressed mathematically. This paper presents a clinically feasible software environment for the quantitative assessment of the relationship among biochemical functions as assessed by PET imaging and electrophysiological parameters derived from intracranial EEG. Based on the developed software tools, quantitative results obtained from individual modalities can be merged into a data structure allowing a consistent framework for advanced data mining techniques and 3D visualization. Moreover, an effort was made to derive quantitative variables (such as the spatial proximity index, SPI) characterizing the relationship between complementing modalities on a more generic level as a prerequisite for efficient data mining strategies. We describe the implementation of this software environment in twelve children (mean age5.2±4.3years) with medically intractable partial epilepsy who underwent both high-resolution structural MR and functional PET imaging. Our experiments demonstrate that our approach will lead to a better understanding of the mechanisms of epileptogenesis and might ultimately have an impact on treatment. Moreover, our software environment holds promise to be useful in many other neurological disorders, where integration of multimodality data is crucial for a better understanding of the underlying disease mechanisms.

• Why are electronic texts suspect? • Can you tear out a page on a screen? • How does chopping up sentences make them coherent? • When do actions speak louder than words? • How can we use questions to map out knowledge needs? . . . We begin this chapter by looking at what is to be gained from understanding the relationship between written and spoken language. The consequences of putting words on the screen are explored, in terms of changes in the meaning of terms, pronunciation, and the effect of spatial proximity on meanings. We then move on to consider aspects of verbal interaction, such as politeness and fluency, and conclude with an overview of users’ knowledge needs identified by analyzing their language. Written texts all have to be related somehow, directly or indirectly, to the world of sound, the natural habitat of language, to yield their meanings. The world of sound as “the natural habitat of language.” Historically, and in an individual’s development, speech comes before writing. For a small child, language is all speech. This is obviously not so for older children and adults, and for some, language is nearly all reading and writing. Still, for most people, language is strongly associated with sound, in a concrete way through hearing and producing language as well as through mental association. In a situation where computers are used, spoken and written language are both present in some way (not necessarily at the same time), not least of all because it is most unusual for someone to use an application without ever speaking about its use! In general, indirect reference from written language to sound through a reader’s prior experience of spoken language or through a special notation is acceptable in many different circumstances, such as in books and newspapers. The question is, What, if anything, do we lose when real sound is missing? Physical demands on the reader (user) are now focused on visual processing.

AbstractIn this article we explore the relationship between spatial proximity and indices of social connectivity during the A.D. 1200–1450 interval in the United States (U.S.) Southwest. Using geographic information systems (GIS), we develop indices of spatial proximity based on the terrain-adjusted cost distance between sites in a regional settlement and material cultural database focused on the western U.S. Southwest. We evaluate the hypothesis that social interaction is a function of proximity and that interactions will be most intense among near neighbors. We find that this hypothesis is supported in some instances but that the correlation between proximity and interaction is highly variable in the context of late precontact social upheaval. Furthermore, we show important discrepancies between the Puebloan north and the Hohokam south that help to explain differences in community sustainability in the two regions.

Abstract In times of educational expansion, privileged families are looking for new strategies of distinction. Referring to Pierre Bourdieu’s theory of distinction, we argue that choosing Latin at school – a language that is no longer spoken and therefore has no direct value – is one of the strategies of privileged families to set themselves apart from less privileged families. Based on two surveys we conducted at German schools, the paper analyzes the relationship between parents’ educational background and the probability that their child will learn Latin. Results indicate that historically academic families have the strongest tendency towards learning Latin, followed by new academic families, and leaving behind the non-academic families. We distinguish between four causal mechanisms that might help to explain these associations: cultural distinction, selecting a socially exclusive learning environment, beliefs in a secondary instrumental function of learning Latin, and spatial proximity between the location of humanist Gymnasiums and the residential areas of privileged families. The hypotheses are formalized by means of Directed Acyclic Graphs (DAG). Findings show that the decision to learn Latin is predominately an unintended consequence of the selection of a socially exclusive learning environment. In addition, there is evidence that especially children from historically academic families learn Latin as a strategy of cultural distinction.

Few studies have used online data collection to study cognitive aging. We used a large (N = 515) online sample to replicate the findings that inattentional blindness increases with age and with the distance of the unexpected object from the focus of attention. Critically, we assessed whether distance moderates the relationship between age and noticing. We replicated both age and distance effects, but found no age by distance interaction. These findings disconfirm a plausible explanation for age differences in noticing (restricted field of view), while for the first time highlighting the advantages and disadvantages of using Mechanical Turk for the study of cognitive aging.

Summary The potential for growth strain measurements for detection of tension wood was assessed in trees from two plantations of 10- to 11-year-old Eucalyptus globulus. Tension wood had commonly developed at or near the stem periphery of straight, vertical and dominant trees. At a localized level growth strain was found to be a good indicator of tension wood. However, in some cases moderate to low growth strain was also detected in some trees where tension wood had been overgrown with small amounts of normal wood. On a whole tree basis the relationship was not as clear. In this case growth strain values determined from multiple measurements appear to be influenced primarily by tissue close to the site of measurements and not by wood at relatively remote locations. In some cases low growth strain values were found in trees with significant tension wood and in others high growth strain values where little tension wood had developed.
