The influence of paternal height and weight on birth-weight

Analysis of 5,989 couples, for whom fathers' and mothers' heights and weights were recorded, showed that paternal height had a significant influence (p less than 0.0007) on birth-weight while paternal body mass index (Quetelets Index) had no significant effect (p greater than 0.05). Depending upon mother's height, the average effect of father's height (ranging from 165 cm to 184 cm) on birth-weight was up to 152 g, with a greater effect where the mother was taller (up to 235 g) and a lesser effect where the mother was shorter (confirming the effect of maternal constraint). The significance of these findings lies more with the need to consider this effect as an important variable in statistical analysis involving birth-weight than in its immediate obstetrical implications

Adoption of cybersecurity policies by local governments 2020

This paper should be of interest to the readers of this journal because it addresses a subject that has received little scholarly attention; namely, local government cybersecurity. The U.S. has over 90,000 units of local government, of which almost 39,000 are “general purpose” units (i.e., municipalities, counties, towns and townships). On average, these governments do not practice cybersecurity effectively (Norris, et al., 2019 and 2020). One possible reason is that they do not adopt and/or implement highly recommended cybersecurity policies. In this paper, we examine local government adoption or lack of adoption of cybersecurity policies using data from three surveys. Norris, et al, 2019 & 2020; Hatcher, et al., 2020; and Norris and Mateczun, 2023. It will probably not be surprising that our first finding is that, by and large, local governments still do a poor good job of adopting and implementing cybersecurity policies. Thus, our first recommendation is that these governments must take whatever actions are needed to ensure high levels of cybersecurity. If they do not, the consequences will be painful and costly, as demonstrated by examples presented in the text. Among these actions, we next recommend that local governments adopt and effectively implement the highly recommended cybersecurity policies discussed in the concluding section. Last, as we have recommended previously, we again call upon local governments to create and maintain within their organizations a culture of cybersecurity – one in which all parties in these governments fully understand and support cybersecurity at the highest levels in their governments

Feelings in Literature

In this article it is argued that feelings are all important to the function of literature. In contradiction to music that is concerned with the inwardness of humankind, literature has, because of language, the capacity to create fictional worlds that in many respects are similar to and related to the life world within which we live. One of the most important reasons for our emotional engagement in literature is our empathy with others and our constant imagining and hypothesizing on possible developments in our interactions with them. Hence, we understand and engage ourselves in fictional worlds. It is further claimed and exemplified, how poetic texts are very good at rhetorically engage and manipulate our feelings. Finally, with reference to the important work of Ellen Dissanayake, it is pointed out that the first kind of communication in which we engage, that between mother and infant, is a kind of speech that positively engages the infant in a dialogue with the mother by means of poetic devices

Causality and the AdS Dirichlet problem

The (planar) AdS Dirichlet problem has previously been shown to exhibit superluminal hydrodynamic sound modes. This problem is defined by bulk gravitational dynamics with Dirichlet boundary conditions imposed on a rigid timelike cut-off surface. We undertake a careful examination of this set-up and argue that, in most cases, the propagation of information between points on the Dirichlet hypersurface is nevertheless causal with respect to the induced light cones. In particular, the high-frequency dynamics is causal in this sense. There are however two exceptions and both involve boundary gravitons whose propagation is not constrained by the Einstein equations. These occur in i) AdS$_3$, where the boundary gravitons generally do not respect the induced light cones on the boundary, and ii) Rindler space, where they are related to the infinite speed of sound in incompressible fluids. We discuss implications for the fluid/gravity correspondence with rigid Dirichlet boundaries and for the black hole membrane paradigm.Comment: 29 pages, 5 figures. v2: added refs. v3: minor clarification

No chiral truncation of quantum log gravity?

At the classical level, chiral gravity may be constructed as a consistent truncation of a larger theory called log gravity by requiring that left-moving charges vanish. In turn, log gravity is the limit of topologically massive gravity (TMG) at a special value of the coupling (the chiral point). We study the situation at the level of linearized quantum fields, focussing on a unitary quantization. While the TMG Hilbert space is continuous at the chiral point, the left-moving Virasoro generators become ill-defined and cannot be used to define a chiral truncation. In a sense, the left-moving asymptotic symmetries are spontaneously broken at the chiral point. In contrast, in a non-unitary quantization of TMG, both the Hilbert space and charges are continuous at the chiral point and define a unitary theory of chiral gravity at the linearized level.Comment: 20 pages, no figures, references adde

Classifying the precancers: A metadata approach

BACKGROUND: During carcinogenesis, precancers are the morphologically identifiable lesions that precede invasive cancers. In theory, the successful treatment of precancers would result in the eradication of most human cancers. Despite the importance of these lesions, there has been no effort to list and classify all of the precancers. The purpose of this study is to describe the first comprehensive taxonomy and classification of the precancers. As a novel approach to disease classification, terms and classes were annotated with metadata (data that describes the data) so that the classification could be used to link precancer terms to data elements in other biological databases. METHODS: Terms in the UMLS (Unified Medical Language System) related to precancers were extracted. Extracted terms were reviewed and additional terms added. Each precancer was assigned one of six general classes. The entire classification was assembled as an XML (eXtensible Mark-up Language) file. A Perl script converted the XML file into a browser-viewable HTML (HyperText Mark-up Language) file. RESULTS: The classification contained 4700 precancer terms, 568 distinct precancer concepts and six precancer classes: 1) Acquired microscopic precancers; 2) acquired large lesions with microscopic atypia; 3) Precursor lesions occurring with inherited hyperplastic syndromes that progress to cancer; 4) Acquired diffuse hyperplasias and diffuse metaplasias; 5) Currently unclassified entities; and 6) Superclass and modifiers. CONCLUSION: This work represents the first attempt to create a comprehensive listing of the precancers, the first attempt to classify precancers by their biological properties and the first attempt to create a pathologic classification of precancers using standard metadata (XML). The classification is placed in the public domain, and comment is invited by the authors, who are prepared to curate and modify the classification
