We examine tick sizes, stock prices, and share turnover in eighteen stock markets in developed countries and find that differences in mandatory tick sizes explain a significant proportion of the variation in stock prices among markets, and that lower percentage tick sizes are not associated with higher turnover. We consider the implications of these findings for the recent decimalization of stock trading in the United States, and conclude that decimal trading is likely to result in lower stock prices (due to stock splits) with no substantial change in dollar trading volume.

In a recent issue of the Journal of Applied Behavioral Science, Blake strongly criticised an article on organisational change by Blumberg and Wiener for the authors' failure thoroughly to review the literature and for missing important material relevant to their study. In response, Blumberg simply stated that they were not aware of the material, because it had appeared in a relatively obscure journal. Indeed, a later writer (Zurcher) criticised one of Blake's papers on the same grounds, and then suggested that an event such as this might easily happen to any of us. Despite their apparent conflict, each of these individuals did agree, of course, that a thorough review of the literature on any given topic is necessary to good research and reporting. Our purpose here is not to pour salt on wounds, but rather to illustrate our raison d'être for presenting the material below.

The purpose of this study is to highlight the experiences and issues of an overlooked demographic: older LGBTQ + adults in the US, in the context of the COVID-19 pandemic. This allows the authors to explore possible changes in policy and practice regarding the management of the pandemic with attention to elderly LGBTQ.

Building on the authors’ experience in disaster research and a study of older LGBTQ + adults in the San Francisco Bay Area, the authors analyze key trends in COVID-19 pandemic management while drawing lessons from the AIDS epidemic.

The authors have found that LGBTQ + people, especially older and transgender individuals, have unique experiences with hazards and public safety and healthcare professionals and organizations (e.g. heteronormative care, traumatic insensitivity, deprioritizing essential treatments as elective). Second, older LGBTQ + adults' perceptions of state responses to pandemics were heavily influenced by experiences with the HIV/AIDS pandemic. And third, experiences with the COVID-19 pandemic have important implications for preventing, responding to and recovering from future epidemics/pandemics.

The authors point to two parallel implications of this work. The first entails novel approaches to queering disaster prevention, response and recovery. And the second is to connect the management of the COVID-19 pandemic to the principles of harm reduction developed by grassroots organizations to suggest new ways to think about contagion and organize physical distancing, while still socializing to take care of people’s physical and mental health, especially the more marginalized like elderly LGBTQ + people.

This paper aims to estimate the performance of the social security administration (SSA) in dealing with disability benefits applications in American.

The authors propose a multi-stage data envelopment analysis (DEA) method to analyze the efficiency of 167 hearing offices (HOs) to find the best performed HOs and inefficient ones and detect total improvement of inefficient and weak efficient offices.

The results show that totally 299,711 applications were processed and more applications will be processed if all offices can work efficiently. To the best of the authors’ knowledge, this paper is the first one to analyze the performance of SSA HOs using the multi-stage DEA method.

To the best of the authors’ knowledge, this paper is the first one to analyze the performance of SSA HOs using the multi-stage DEA method.

The goal of this chapter is to both provide a sociological explanation for gender differences in risk-taking behavior and to explain how such gender differences in behavior may contribute to women’s underrepresentation at the top of hierarchies.

I synthesize relevant research findings from the fields of social psychology, economics, psychology, decisions science, and sociology.

I argue that risk-taking is a gendered action due to both prescriptive and descriptive gender stereotypes. The fact that risk-taking is a gendered action offers sociological insights as to why women take fewer risks than men. First, women may rationally choose to take fewer risks, given that risk-taking is less rewarding for them. Second, the aforementioned gender stereotypes may cause institutional gatekeepers to give women fewer opportunities to take risks.

Sociologists should care about this phenomenon because large rewards are attached to successful risk-taking behavior. Thus, if men as a group take more successful risks than women as a group – simply because they take more risks, and thus by chance experience more successful risks – then more men than women will experience upward mobility caused by risk-taking.

Gender differences in risk-taking behavior likely depress the upward mobility of women and are a contributing factor to the dearth of women in top positions. In this era of falling formal barriers and women’s educational gains, gender differences in risk-taking behavior are likely of increasing importance for understanding the inequalities in hierarchies in U.S. society.

AFTER some unsuccessful negotiations during the period when the first full‐time schools of librarianship were being established, the Birmingham School was founded in the autumn of 1950. Circumstances were not entirely favourable—the immediate post‐war generation of enthusiastic ex‐service students had already passed through other schools; the accommodation available was indifferent; the administrative support was bad; resources were weak, both in books and in equipment. There was, more importantly, a strong local tradition of part‐time classes in librarianship and little or no conviction that full‐time study was necessary or desirable.

This article reviews the telecommunications environment and infrastructure, discusses the major forces influencing change within this environment, and suggests certain likely outcomes, as seen by the author, that will have significant influences on the future telecommunications infrastructure. This information is then used as the basis for assessing likely impacts on various aspects of library and information systems, their providers and users. Specifically discussed are impacts foreseen for: 1) national online information providers; 2) local online information providers; 3) local and long‐distance telephone companies as providers of information; and 4) users of information. Impacts on library and information system‐related endeavors are seen to be generally unfavorable in the near term, with information delivery costs seen to rise significantly in the next three to five years. A more favorable prognosis, however, is seen for the longer term.
