Prispevek obravnava predstave in odnos mladih do migracijskih procesov v dveh državah – ZDA, ki že stoletja veljajo za državo priseljevanja, in Sloveniji, ki je bila v različnih zgodovinskih obdobjih ...del različnih migracijskih procesov (kot država izseljevanja, država priseljevanja ali država tranzitnih migracij). Prvi del prispevka se osredotoča na migracijske procese v obeh državah in prikaže pregled predstav in odnosa mladih do priseljevanja, drugi del pa predstavi rezultate raziskave, ki smo jo opravili med 44 mladimi Američani in Slovenci, v kateri so nas zanimale njihove predstave in odnos do migracijskih procesov.
This article studies novel attack and defense strategies, based on a class of stealthy attacks, namely the zero-dynamics attack (ZDA), for multiagent control systems. ZDA poses a formidable security ...challenge since its attack signal is hidden in the null space of the state-space representation of the control system and hence it can evade conventional detection methods. An intuitive defense strategy builds on changing the aforementioned representation via switching through a set of carefully crafted topologies. In this article, we propose realistic ZDA variations where the attacker is aware of this topology-switching strategy, and hence employs the following policies to avoid detection: first, pause, update, and resume ZDA according to the knowledge of switching topologies; and second, cooperate with a concurrent stealthy topology attack that alters network topology at switching times, such that the original ZDA is feasible under the corrupted topology. We first systematically study the proposed ZDA variations, and then develop defense strategies against them under the realistic assumption that the defender has no knowledge of attack starting, pausing, and resuming times and the number of misbehaving agents. Particularly, we characterize conditions for detectability of the proposed ZDA variations, in terms of the network topologies to be maintained, the set of agents to be monitored, and the measurements of the monitored agents that should be extracted, while simultaneously preserving the privacy of the states of the nonmonitored agents. We then propose an attack detection algorithm based on the Luenberger observer, using the characterized detectability conditions. We provide numerical simulation results to demonstrate our theoretical findings.
The opioid crisis in the United States has come about because of excessive use of these drugs for both legal and illicit purposes and unprecedented levels of consequent opioid use disorder (OUD). ...More than 2 million people in the United States are estimated to have OUD, which is caused by prolonged use of prescription opioids, heroin, or other illicit opioids. OUD is a life-threatening condition associated with a 20-fold greater risk of early death due to overdose, infectious diseases, trauma, and suicide. Mortality related to OUD continues to escalate as this public health crisis gathers momentum across the country, with opioid overdoses killing more than 47,000 people in 2017 in the United States. Efforts to date have made no real headway in stemming this crisis, in large part because tools that already exist?like evidence-based medications?are not being deployed to maximum impact.
To support the dissemination of accurate patient-focused information about treatments for addiction, and to help provide scientific solutions to the current opioid crisis, this report studies the evidence base on medication assisted treatment (MAT) for OUD. It examines available evidence on the range of parameters and circumstances in which MAT can be effectively delivered and identifies additional research needed.
A major theoretical statement by a distinguished political scholar explains why a policy of liberal hegemony is doomed to failIn this major statement, the renowned international-relations scholar ...John Mearsheimer argues that liberal hegemony, the foreign policy pursued by the United States since the Cold War ended, is doomed to fail. It makes far more sense, he maintains, for Washington to adopt a more restrained foreign policy based on a sound understanding of how nationalism and realism constrain great powers abroad.It is widely believed in the West that the United States should spread liberal democracy across the world, foster an open international economy, and build institutions. This policy of remaking the world in America's image is supposed to protect human rights, promote peace, and make the world safe for democracy. But this is not what has happened. Instead, the United States has ended up as a highly militarized state fighting wars that undermine peace, harm human rights, and threaten liberal values at home. Mearsheimer tells us why this has happened.
The Great Recession, institutional dysfunction, a growing divide between urban and rural prospects, and failed efforts to effectively address immigration have paved the way for a populist backlash ...that disrupts the postwar bargain between political elites and citizens. Whether today's populism represents a corrective to unfair and obsolete policies or a threat to liberal democracy itself remains up for debate. Yet this much is clear: these challenges indict the triumphalism that accompanied liberal democratic consolidation after the collapse of the Soviet Union. To respond to today's crisis, good leaders must strive for inclusive economic growth while addressing fraught social and cultural issues, including demographic anxiety, with frank attention. Although reforms may stem the populist tide, liberal democratic life will always leave some citizens unsatisfied. This is a permanent source of vulnerability, but liberal democracy will endure so long as citizens believe it is worth fighting for.
STEM Integration in K-12 Education examines current efforts to connect the STEM disciplines in K-12 education. This report identifies and characterizes existing approaches to integrated STEM ...education, both in formal and after- and out-of-school settings. The report reviews the evidence for the impact of integrated approaches on various student outcomes, and it proposes a set of priority research questions to advance the understanding of integrated STEM education. STEM Integration in K-12 Education proposes a framework to provide a common perspective and vocabulary for researchers, practitioners, and others to identify, discuss, and investigate specific integrated STEM initiatives within the K-12 education system of the United States.
STEM Integration in K-12 Education makes recommendations for designers of integrated STEM experiences, assessment developers, and researchers to design and document effective integrated STEM education. This report will help to further their work and improve the chances that some forms of integrated STEM education will make a positive difference in student learning and interest and other valued outcomes.
Greater racial diversity is good news for America's future
Race is once again a contentious topic in America, as shown by the divisive rise of Donald Trump and the activism of groups like Black Lives ...Matter. YetDiversity Explosionargues that the current period of profound racial change will lead to a less-divided nation than today's older whites or younger minorities fear. Prominent demographer William Frey sees America's emerging diversity boom as good news for a country that would otherwise face declining growth and rapid aging for many years to come.
In the new edition of this popular Brookings Press offering, Frey draws from the lessons of the 2016 presidential election and new statistics to paint an illuminating picture of where America's racial demography is headed-and what that means for the nation's future.
Using the U.S. Census, national surveys, and related sources, Frey tells how the rapidly growing "new minorities"-Hispanics, Asians, and multiracial Americans-along with blacks and other groups, are transforming and reinvigorating the nation's demographic landscape. He discusses their impact on generational change, regional shifts of major racial groups, neighborhood segregation, interracial marriage, and presidential politics.
Diversity Explosionis an accessible, richly illustrated overview of how unprecedented racial change is remaking the United States once again. It is an essential guide for political strategists, marketers, investors, educators, policymakers, and anyone who wants to understand the magnitude, potential, and promise of the new national melting pot in the twenty-first century.

For patients and their loved ones, no care decisions are more profound than those made near the end of life. Unfortunately, the experience of dying in the United States is often characterized by ...fragmented care, inadequate treatment of distressing symptoms, frequent transitions among care settings, and enormous care responsibilities for families. According to this report, the current health care system of rendering more intensive services than are necessary and desired by patients, and the lack of coordination among programs increases risks to patients and creates avoidable burdens on them and their families. Dying in America is a study of the current state of health care for persons of all ages who are nearing the end of life.
Death is not a strictly medical event. Ideally, health care for those nearing the end of life harmonizes with social, psychological, and spiritual support. All people with advanced illnesses who may be approaching the end of life are entitled to access to high-quality, compassionate, evidence-based care, consistent with their wishes.
Dying in America evaluates strategies to integrate care into a person- and family-centered, team-based framework, and makes recommendations to create a system that coordinates care and supports and respects the choices of patients and their families. The findings and recommendations of this report will address the needs of patients and their families and assist policy makers, clinicians and their educational and credentialing bodies, leaders of health care delivery and financing organizations, researchers, public and private funders, religious and community leaders, advocates of better care, journalists, and the public to provide the best care possible for people nearing the end of life.
Contesting the assumption that early American economists were committed to Adam Smith's ideas of free trade and small government, this book provides a comprehensive history of the nation's economic ...thought from 1790 to 1860, tracing the development of a uniquely American understanding of capitalism.
