In the 1880s, women were barred from voting in all national-level elections, but by 1920 they were going to the polls in nearly thirty countries. What caused this massive change? Contrary to conventional wisdom, it was not because of progressive ideas about women or suffragists' pluck. In most countries, elected politicians fiercely resisted enfranchising women, preferring to extend such rights only when it seemed electorally prudent and necessary to do so. This book demonstrates that the formation of a broad movement across social divides, and strategic alliances with political parties in competitive electoral conditions, provided the leverage that ultimately transformed women into voters. As the book shows, in competitive environments, politicians had incentives to seek out new sources of electoral influence. A broad-based suffrage movement could reinforce those incentives by providing information about women's preferences, and an infrastructure with which to mobilize future female voters. At the same time that politicians wanted to enfranchise women who were likely to support their party, suffragists also wanted to enfranchise women whose political preferences were similar to theirs. In contexts where political rifts were too deep, suffragists who were in favor of the vote in principle mobilized against their own political emancipation. Exploring tensions between elected leaders and suffragists and the uncertainty surrounding women as an electoral group, the book sheds new light on the strategic reasons behind women's enfranchisement.

AbstractThis paper characterizes whether or not\Sigma_{\infty}\equiv\lim_{\lambda\uparrow\infty}\sigma[\mathcal{P}+\lambda m(% x,t),\mathfrak{B},Q_{T}]is finite, where {m\gneq 0} is T-periodic and {\sigma[\mathcal{P}+\lambda m(x,t),\mathfrak{B},Q_{T}]} stands for the principal eigenvalue of the parabolic operator {\mathcal{P}+\lambda m(x,t)} in {Q_{T}\equiv\Omega\times[0,T]} subject to a general boundary operator of mixed type, {\mathfrak{B}}, on {\partial\Omega\times[0,T]}. Then this result is applied to discuss the nature of the territorial refuges in periodic competitive environments.

Summary The incidental mortality of seabirds in fisheries remains a serious global concern. Obtaining unbiased and accurate estimates of bycatch rates is a priority for seabird bycatch mitigation and demographic research. For measuring the capture risk of seabird interactions in fisheries, the rate of carcass retrieval from hauled gear is commonly used. However, reliability can be limited by a lack of direct capture observations and the substantial pre-haul bycatch losses known to occur, meaning incidence of seabird bycatch is underestimated. To solve this problem, a new measure (bycatch vulnerability) that links an observed interaction directly to the underlying capture event is proposed to represent the capture risk of fishery interactions by seabirds. The new measure is not affected by subsequent bycatch loss. To illustrate how to estimate and analyse bycatch vulnerability, a case study based on a long-term dataset of seabird interactions and capture confirmation is provided. Bayesian modelling and hypothesis testing were conducted to identify important bycatch risk factors. Competition was found to play a central role in determining seabird bycatch vulnerability. More competitive environments were riskier for seabirds, and larger and thus more competitive species were more at risk than smaller sized and less competitive species. Species foraging behaviour also played a role. On the other hand, no additional effect of physical oceanic condition and spatio-temporal factors on bycatch vulnerability was detected. Bycatch vulnerability is recommended as a replacement for the commonly used bycatch rate or carcass retrieval rate to measure the capture risk of an interaction. Combined with a normalized contact rate, bycatch vulnerability offers an unbiased estimate of seabird bycatch rate in pelagic longline fisheries.

Evolving media landscapes toward increasingly diverse and competitive environments in both traditional and new media requires producers regularly examine the quality of their productions. One growing line of research identifies the increasing presence and significance of statistics in sports media programming. This experiment measures the effect of statistics on enjoyment and perceived credibility by sport consumers while considering level of fanship, media source, and variations in placement within Instagram posts. Results uncover evidence that validates previous observations about statistics in media while contradicting others. Specifically, findings reveal that statistics enhance enjoyment and improve perceived credibility. Observations were consistent across fanship level. However, additional findings also suggest media source and placement of statistics influences both enjoyment and credibility as well. For both dependent variables, statistics in both the Instagram caption and image yielded significantly greater enjoyment and credibility than some other conditions including posts without statistics at all. The impact of these and other findings on sports media industry and scholarship, along with limitations and directions for future research, are discussed.

This study investigated the efficiency performance of the production technology of the Department of Health (DOH)-affiliated hospital system in Taiwan in different competitive environments. This study used Data Envelopment Analysis (DEA) to analyze a total of 396 hospitals of different systems in Taiwan. The results indicated that, in terms of the internal competitive environment, the production performance of hospital Q was the best, while that of hospital N was the worst. This study also analyzed the production performance and scale of DOH-affiliated hospitals and provided hospitals with a direction for scale development. Finally, this study proposed suggestions on improvement direction for hospitals with poor production performance. As for external competitive environment, there is no significant difference in the average efficiency among various hospital systems. However, there are a lot to be improved in DOH-affiliated hospitals, especially in the aspect of technology efficiency. The improvement of technology efficiency should be more beneficial to the overall efficiency.

Drawing primarily on the literature in experimental economics and social psychology, this article reviews key findings on gender differences for two aspects of competitiveness and competition: entry preferences and performance. Although women, relative to men, have been shown to shy away from competition and underperform in competitive environments, this article also discusses boundary conditions for these effects, such as the nature of the task or gender composition of the group, and highlights manifestations of these effects in applied domains, including in negotiations, the labor market, educational settings, and sports. Adopting social psychological frameworks of prescriptive norms and stereotypes, particularly social role theory, this article examines ways in which gender-incongruencies may underpin gender gaps in competition and gender-congruencies may alleviate them. Finally, this article considers implications for individuals and institutions as well as future directions in the field to continue finding ways to close gaps.
