The number of objects in Earth’s orbit has continued to grow since the space race between the United States and the Soviet Union. The historical “few objects, large space” principle left satellite operations a relatively benign environment, but that construct has shifted significantly due to the advent of the commercial space sector, the small satellite industry boom, and the resurgence of the desire for human space flight. The regulations for space operations both at the international and national level have always been sparse, but there is a large desire for more now that commercial capital is at stake. The purpose of this article is to bring to the surface available regulations for on-orbit operations to identify the gaps to fill and highlight the change for the Department of Defense. The international community and commercial sector recognize the need for a state like the United States to set a standard to influence the international community. This national-to-international framework is a technique used in other arenas, such as maritime traffic management and air traffic management, and the lessons learned from these fields are applicable to the space domain. 相似文献

Scotland’s future within the European Union (EU) played a prominent role in the 2014 independence referendum. The story goes that latent supporters of independence voted to stay within the UK to maintain EU access. Defeated, Scottish leaders declared the referendum a once-in-a-life-time event only repeated if conditions substantially changed. With the UK now facing a chaotic exit from the EU, proponents of Scottish independence have suggested that a second referendum may occur after Brexit negotiations are completed. Faced with a consensus among Scottish party leaders in supporting EU membership, those hoping for a second independence referendum, we argue, looked to alternate sources of information that saw Brexit as an opportunity to create the conditions that would spur a second referendum. Using panel data from the British Election Study, we examine whether Scottish voters voted tactically to leave the EU. We argue that Scottish National Party voters were likely to interpret statements on the conditions for a second independence referendum as an implicit signal to vote “Leave.” The results have important implications for the role of referendums in representative democracy, strategic voting, and the importance of intra-party division on individual vote choices. 相似文献

Right-wing populist parties portray immigrants as economic or symbolic threats in their political advertisements by constructing a moral divide between the “good” ordinary people and “bad” immigrants. Yet, it remains unclear how these different threat appeals contribute to the formation of anti-immigrant attitudes among citizens and what role visual elements play in producing these effects. A survey-experiment with a quota sample of 471 participants reveals that, overall, symbolic threat appeals exert stronger effects on anti-immigrant attitudes than economic ones. When presented via text alone, only symbolic—not economic—threat appeals increased anti-immigrant attitudes via the activation of heuristic processing such as the reliance on negative stereotypes or feelings of anxiety, in particular among lower-educated citizens. When visuals were present, both types of threat appeals enhanced anti-immigrant attitudes among citizens across all education levels based on heuristic processing. Additionally, high image-text congruency induced cognitive argument approval resulting in higher anti-immigrant attitudes. 相似文献

This article argues that the effectiveness of the tactics ruling parties use to control the electoral arena may depend on the electoral experience of its subordinates. To substantiate this point, the work examines Russia’s “locomotives” – the practice of placing regional governors on the list of the ruling party, United Russia, during national legislative elections. It argues that electoral payoffs also came from select regions without locomotives. Given the move to appointed governors, list exclusion likely indicated gubernatorial vulnerability. As a result, governors left off United Russia’s list may have responded by seeking to demonstrate their electoral utility, and those with longer tenures were more likely to succeed in these efforts. An analysis of the 2007 Duma elections shows that United Russia’s vote share was higher in regions where long-serving governors were left off the list. Since Russia’s appointment system dramatically changed the gubernatorial corps between 2007 and 2011, the article also considers changes in the effects of list placement over time. It finds that the relationship between list exclusion and higher vote shares for United Russia disappears as governors with electoral experience were removed from office. 相似文献

The ongoing health crisis in the Ukraine has persisted for 48 years with a clear division of gender-based outcomes as seen in the decline of male life expectancy and stagnation of female longevity. The purpose of this paper is to investigate differences in self-rated health and system barriers to health care applicable to gender and its intersections because of the differing negative health outcomes for men and women. Intersectionality theory provides an analytic framework for interpreting our results. Utilizing a nationwide sample of the Ukrainian population (N = 1908), we found that low socioeconomic status (SES) women rate their health worse than men generally and any other socioeconomic group. Yet women also face the greatest barriers to health care until older ages when the ailments of men cause them to likewise face the obstacles. In reviewing the barrier to health care scale, one barrier—that of health care services being too expensive—dominated the responses with some 52.5 percent of the sample reporting it. Consequently, the greatest problem in Ukraine with respect to health reform reported by the population is the out-of-pocket costs for care in a system that is officially free. These costs, constituting some 40 percent of all national health expenditures, affect women and the aged the most. 相似文献

Are internalizing and externalizing behavior problems interrelated via mutually reinforcing relationships (with each behavior leading to increases over time in levels of the other behavior) or mutually suppressing relationships (with each behavior leading to decreases over time in levels of the other behavior)? Past research on the directionality of these relationships has led to ambiguous results, particularly in adolescence. Furthermore, the extent to which prior results will generalize to adolescents with low levels of cognitive abilities remains unknown. This second limit is particularly important, given that these adolescents are known to present higher levels of externalizing and internalizing behaviors than their peers with average-to-high levels of cognitive abilities, and that the mechanisms involved in the reciprocal relationships between these two types of behaviors may differ across both populations. This study examines the directionality of the longitudinal relationships between externalizing and internalizing behavior problems as rated by teachers across three measurement waves (corresponding to Grades 8–10) in matched samples of 138 adolescents (34.78?% girls) with low levels of cognitive abilities and 556 adolescents (44.88?% girls) with average-to-high levels of cognitive abilities. The results showed that the measurement structure was fully equivalent across time periods and groups of adolescents, revealing high levels of developmental stability in both types of problems, and moderately high levels of cross-sectional associations. Levels of both internalizing and externalizing behaviors were higher among adolescents with low levels of cognitive abilities relative to those with average-to-high levels of cognitive abilities. Finally, the predictive analyses revealed negative reciprocal longitudinal relationships (i.e., mutually suppressing relationships) between externalizing and internalizing problems, a result that was replicated within samples of adolescents with low, and average-to-high levels of cognitive ability. 相似文献
