Unbraced cables

For long span cables, either with or without concentrated load, the usual methods of design are found to be inaccurate because they omit the elastic stretch of the cable and they assume an inaccurate shape of the resulting curve. Equations are derived to cover all possible cases, loaded and unloaded cable, based upon assumptions of elastic flexible cables with fixed supports. Equations are also derived showing the variation in several quantities with changes in temperature and movement of supports. Conditions of possible loads and elastic properties of cables are discussed. A bibliography covering major references to the subject is included.     

Audience Currencies in the Age of Big Data

ABSTRACT

Audience ratings data have long occupied the attention of marketers and media managers. These are the “currencies” that support the operation of commercial media. Today, metrics can be derived from many large datasets, raising the possibility that new kinds of currencies might emerge. We argue that data on exposure are the most likely to support currencies, and that these might well go beyond traditional measures of audience size and composition. We explore the relationship between the most plausible contenders for audience currencies: size and engagement as measured by time spent. Contrary to the “Law of Double Jeopardy,” we find these metrics to be uncorrelated in an online environment, suggesting that each might have a role to play as a currency. We conclude with a discussion of how the political economy of audience measurement is likely to affect audience currencies in the age of big data.     

Full Steam Ahead: A Conceptual Analysis of User-Supplied Tags on Steam

This article describes a conceptual analysis of user-generated tags applied to video games in the Steam video game distribution system. The research team scraped all user-generated tags available on Steam and then conducted a conceptual analysis of the tags, sorting them into categories and comparing them to the current version of the Video Game Metadata Schema. This analysis allowed the team to identify new metadata elements and terms useful to game players. We present a discussion covering the major issues in organizing the terms, as well as the implications for the future work in the area of video game metadata.     

CORRELATES OF PURE AND CO‐OCCURRING PROACTIVE AND REACTIVE AGGRESSORS IN HONG KONG

Research on aggression in the West has focused mainly on the dichotomy between proactive and reactive aggression, but not the co‐occurring proactive–reactive aggression subtype, despite its prevalence. The authors investigated the differences in psychological and behavioral correlates among proactive, reactive, and proactive–reactive student aggressors and nonaggressors in Hong Kong, China, based on their scores on the Reactive and Proactive Aggression Questionnaire. Participants were 1,356 secondary school students (805 males and 551 females, aged 11 to 18 years). A one‐way multivariate analysis of covariance was conducted to examine group differences in aggression, attention deficits, anxiety/depression, and delinquency. Results showed that proactive–reactive aggressors were significantly more aggressive, less attentive, more anxious/depressed, and more engaged in delinquent behaviors. Reactive and proactive aggressors did not differ in three of these four behaviors. Implications for research and practice when working with proactive–reactive aggressors are discussed.     

CRITICAL PEDAGOGY AND FAITH

Critical pedagogy has often been linked in the literature to faith traditions such as liberation theology, usually with the intent of improving or redirecting it. While recognizing and drawing from those previous linkages, Jacob Neumann goes further in this essay and develops the thesis that critical pedagogy can not just benefit from a connection with faith traditions, but is actually, in and of itself, a practice of faith. In this analysis, he juxtaposes critical pedagogy against three conceptualizations of faith: John Caputo's blurring of the modernist division between faith and reason, Paul Tillich's argument that faith is “ultimate concern,” and Paulo Freire's theology and early Christian influences. Using this three‐pronged approach, Neumann argues that regardless of how it is seen, critical pedagogy manifests as a practice of faith “all the way down.”
