Role Theory in Foreign Policy
Authors: Breuning Marijke
Published: September 2017

Role theory first emerged as an approach to the study of foreign policy with the seminal work of Holsti, who argued that decision makers’ conceptions of their state’s role on the world stage influenced that state’s foreign policy behavior. Holsti’s approach was ahead of its time. The potential of role theory to contribute to the agent-structure debate has not always been appreciated. In fact, early research employing role theory often maintained a close connection to structural theories of international relations, especially among U.S.-based scholars.

In the last decade or so, there has been a renewed interest in role theory that differs from earlier work in that it more clearly connects with psychological approaches to foreign policy analysis. It also takes more seriously the domestic sources of role theory through inquiry into horizontal and vertical role contestation. Much of this new work intersects with constructivism, although it remains grounded in empiricism.

As foreign policy analysis increasingly seeks to understand the foreign policies of a broader array of states—including smaller states that face significant constraints on their ability to act in the international arena—role theory provides an attractive framework. Its focus on decision makers’ conceptions of their state’s role in international politics enhances the ability to make sense of the foreign policies of a wider array of states in the global arena. In essence, role theory allows foreign policy analysis to move beyond a U.S.-centric or global-north-centric field to become more broadly comparative.
What Do We Know About Civil War Duration? A Bargaining Perspective
Authors: Cunningham David E.
Published: September 2017

Civil wars vary greatly in duration—some end within months; others last for decades. What explains this variation? Civil wars drag on when no combatant can win a military victory and the various actors involved are unable, or unwilling, to reach a compromise agreement that resolves the war. Military victory does happen in civil war, but it is rare, so understanding why civil wars last as long as they do requires examining the barriers to negotiated settlement.

Wars last longer when the parties involved perceive the war as less costly relative to peace and when the combatants are overly optimistic about how they will do in the war. Even when key decision-makers see the war as costly and are realistic about their chances of prevailing, negotiated settlements prove elusive if the parties cannot accept a division of the issues at stake or if the government or rebels are unable to trust the commitments the other side makes in a negotiation. Additionally, bargaining is more complicated when there are more combatants that must accept the terms of any agreement, and conflicts with more combatants last much longer than those with fewer.

Many factors affect the bargaining environment, and these barriers to bargaining can explain why civil wars are on average quite long. International actions can alleviate some of the barriers and help combatants reach comprehensive settlements, as happened in the conflicts in Mozambique, El Salvador, Guatemala. In particular, peacekeeping and mediation strategies are effective at resolving wars sooner. International action in general is more effective, however, when the parties involved are interested in peace but need some help overcoming commitment or informational problems. These actions are much less successful when that interest is lacking.

The current civil war in Syria has many of the factors identified as prolonging wars. It is an extremely fractionalized conflict, and many external actors are involved. Syria has a large majority population that has been historically excluded from political power and economically marginalized, and a minority government that has been dominant. These factors make reaching a comprehensive settlement very challenging and mean the war is likely to be very long-lasting.
Regions of War and Peace in Foreign Policy
Authors: Weisiger Alex
Published: September 2017

A significant, if minority, current in contemporary international relations scholarship places regions at the center of analysis. In practice, the shift to the regional level of analysis serves several purposes within international relations scholarship. Within the sociology of the discipline, regionalism provides a theoretical justification for work that in earlier periods would have been associated with traditional area studies. Within the broader international relations literature, a regional focus allows for a more nuanced analysis of war and peace outside of the core great power conflicts at the center of traditional analysis. In particular, regional approaches remind us that conflict at the regional level is driven more frequently by local than by global concerns while providing a framework for studying important conflicts that are not simply a manifestation of great power rivalries. Finally, this approach is essential for answering questions that can be couched only at the regional level of analysis. At a narrow level, regional approaches are particularly useful for specifying the dangers of conflict spillover and the actors who are most vulnerable to such spillover. At the broadest level, regional conflict systems become the unit of analysis for work examining why some regions are more peaceful than others and how violent regions may transition to peace. A good understanding of these questions has implications both for policymakers seeking to advance national interests and for peacemakers seeking a solution to violence.
The Aftermaths of Civil Conflicts
Authors: Johnson Jaclyn M. , Thyne Clayton L.
Published: September 2017

The devastating Syrian civil war that began after the Arab Spring in 2011 has reminded the international community of the many consequences of civil war. However, this conflict is simply one of many ongoing conflicts around the globe. Civil war has a number of effects on individual lives, the country experiencing the conflict, as well as the international system more broadly.

The humanitarian costs of civil war are steep. Individuals are negatively impacted by civil war in a myriad of ways. Three main areas of research are of interest: mortality, physical and mental trauma, and education. Several factors increase the number of deaths in a civil war, including a lack of democracy, economic downturns, and foreign assistance to combatants. Even if civilians survive conflict, they are likely to endure trauma that affects both mental and physical health. Strong evidence indicates that civil war spreads infectious diseases and severely diminishes life expectancy. Mental health is also likely to suffer in the face of conflict, as individuals often must overcome debilitating trauma. Finally, children are particularly susceptible in civil war settings. Children are often unable to continue their education as a consequence of civil war because combatants often target schools strategically or the state is unable to fund education as a result of funneling resources to the conflict.

Civil wars also pose a number of threats to the state itself. First, a state that has experienced a civil war is much more likely to have another civil war in its future. Conflict recurrence has been explained through the type of settlement that concludes the initial civil war, institutions that may prevent recurrence like proportional representation, and the role of third parties in providing peace-ensuring security guarantees. Beyond recurrence of war, scholars have looked at the impact that civil wars have on state-level institutions, including democratization. While most state-level effects of civil war seem to be deleterious, there may also be positive effects, specifically in terms of female representation. Civil war in sub-Saharan Africa has been shown to increase the number of female representatives, perhaps providing an avenue for gender equality.

Civil wars have ripple effects that impact neighboring countries and the international system more broadly. Proximate states are often challenged with an influx of refugees that may burden social programs or facilitate the spread of diseases and illicit arms. However, positive consequences of hosting refugees may include trading opportunities or economic growth from remittances. Moving beyond proximate states, civil wars have consequences for the entire globe. For example, civil wars have been demonstrated to spur international terrorism. The civil war literature has explored the various effects of conflict at the individual, state, and interstate level.
The State of Hezbollah? Sovereignty as a Potentiality in Global South Contexts
Authors: Mansour Imad
Published: September 2017

The understanding of the differences in what a state and nonstate actors are and do in the Global South is augmented if we historicize these categories. In particular, the category of the nonstate actor is best understood when contextualized in the project of the state in which such actors operate. Building on established critical approaches, it is necessary to interrogate the a priori assumption that distinctions that frame as exclusively distinct categories of state and nonstate actors hold blanket validity for understanding politics in the Global South.

A meaningful understanding of how an actor’s influence—regardless of category—is enhanced when placed in a context, and where analysis addresses strategies and actions and their effects. To this end, an actor is defined as an entity with two characteristics: it is able to develop preferences and goals, and it is able to mobilize individuals and material resources in their pursuit. Presenting the benefits of contextual analysis shows how a focus on actors’ “sovereign potentialities” (i.e., attributes such as control over territory, service provision, generation of markers of identity, and the international recognition that an actor has and through which it can impose change on its context and environment) allows for a clearer understanding of what constrains or enables actors qua actors.

One way to explain the analytical purchase of this argument is via a novel reading of Hezbollah and of Lebanon’s politics, which is the party’s anchoring context. This makes it possible to analyze the profound effects of Hezbollah’s actions in Lebanon and regionally through its alliance with Syria (and Iran), its appeal to a wider Arab audience, and its confrontation with Israel. Special attention is given to Hezbollah’s actions in Lebanon, its involvement in the 2012–2013 Qusayr battle in support of the Syrian government, and its decision-making during the 2006 Israel War. This discussion will highlight Hezbollah’s state-like and non-state-like sovereign potentialities, and the factors that limit or enable its strategies in different contexts.
Left-Right Orientations and Voting Behavior
Authors: Jou Willy , Dalton Russell J.
Published: September 2017

One of the ways that citizens and elites orient themselves to politics is in reference to a Left-Right vocabulary. Left and Right, respectively, refer to a specific set of progressive and conservative policy preferences and political goals. Thus, Left-Right becomes a framework for positioning oneself, political figures, and political parties into a common framework. Most citizens identify themselves in Left-Right terms and their distribution of these orientations vary across nations. These orientations arise both from long-term societal influences and from the short-term issues of the day. Most people also place political parties in Left-Right terms. This leads citizens to use Left-Right comparisons as an important factor in their voting choice, although this impact varies considerably across nations. Most parties attract voters that broadly share their Left-Right orientations.
History of Sport, Exercise, and Performance Psychology in North America
Authors: Granito Vincent J.
Published: September 2017

The history of sport, exercise, and performance psychology in North America dates back to the late 1800s. However, these professionals typically conducted research in the area of motor learning and development, with little connection to other efforts and researchers. They struggled to forge an identity with the parent disciplines of psychology and physical education. By the 1930s, sport psychology was beginning to take shape in the form of topics that would become the foundation of the field. Professionals were also starting to provide services to athletes, such as Coleman Griffith with the Chicago Cubs in 1938. The field came into its own during the 1950s and 1960s as established research labs and educational opportunities became available to students who would go on to develop further opportunities during the 1970s and 1980s. The scholarly journals were launched, professional organizations were set up, and graduate programs were created. Exercise psychology became a subdivision of the field during the 1970s fitness craze, and performance psychology developed into a specialty in the 1980s. This rich history provides a framework for the current makeup of the field and direction for the future.
Visual Representations of the Genocide
Authors: Elander Maria
Published: September 2017

It is often stated that it is not possible to completely understand genocide: its horror and suffering defy complete representation. For those not immediately affected by the horror, representations of genocide through photography and film are often the primary form through which genocide is encountered. It is possible to discern two key questions underpinning scholarship that engages with representations of genocide in photography and film: First, to what extent can photos and film document and thereby provide evidence of genocide? One version of this question is linked to that of examining “truths” about genocide—whether genocide occurred and understanding its intricacies. Another leads to questions about the role of photography as evidence and its limits in providing “truths.” The second central question in the scholarship concerns the role that photos and film hold in bearing witness to genocide. Here, the scholarship tends to be framed not so much a question as an impetus to “never forget” or “never again.”

During the Khmer Rouge genocide, somewhere between 1.5 and 2.25 million people were killed. While most killings do not meet the legal elements of genocide, the event is nevertheless colloquially known as genocide. Among the most known photographs from the period are the photographs taken at the security center S-21. Today, they stand as representative of the victims of the Khmer Rouge and have appeared at genocide museums, research archives, institutions of art, and as illustrations for various legal claims. The debates that have accompanied these appearances are illustrative of the debates on images of genocide more generally, focusing on, for example, limits of representation, the appropriate place for such photographs. and claims of voyeurism. Numerous films have been made about the Khmer Rouge period, some of which have been major commercial successes, others have been independent documentaries. Films such as The Killing Fields and The Missing Picture can be seen as bearing witness to the genocide, whereas documentaries such as S21: The Khmer Rouge Killing Machine pose intricate questions about responsibility. Finally, it is noteworthy to pay attention to the way film appears within criminal proceedings, as this sheds light on the different understandings of evidence when the task is to bear witness and assign responsibility.
Motion Processing in Primates
Authors: Manning Tyler S. , Britten Kenneth H.
Published: September 2017

The ability to see motion is critical to survival in a dynamic world. Decades of physiological research have established that motion perception is a distinct sub-modality of vision supported by a network of specialized structures in the nervous system. These structures are arranged hierarchically according to the spatial scale of the calculations they perform, with more local operations preceding those that are more global. The different operations serve distinct purposes, from the interception of small moving objects to the calculation of self-motion from image motion spanning the entire visual field. Each cortical area in the hierarchy has an independent representation of visual motion. These representations, together with computational accounts of their roles, provide clues to the functions of each area. Comparisons between neural activity in these areas and psychophysical performance can identify which representations are sufficient to support motion perception. Experimental manipulation of this activity can also define which areas are necessary for motion-dependent behaviors like self-motion guidance.
Auditory Hair Cells and Sensory Transduction
Authors: Holt Jeffrey R. , Géléoc Gwenaëlle S.G.
Published: September 2017

The organs of the vertebrate inner ear respond to a variety of mechanical stimuli: semicircular canals are sensitive to angular velocity, the saccule and utricle respond to linear acceleration (including gravity), and the cochlea is sensitive to airborne vibration, or sound. The ontogenically related lateral line organs, spaced along the sides of aquatic vertebrates, sense water movement. All these organs have a common receptor cell type, which is called the hair
cell, for the bundle of enlarged microvilli protruding from its apical surface. In different organs, specialized accessory structures serve to collect, filter, and then deliver these physical stimuli to the hair bundles. The proximal stimulus for all hair cells is deflection of the mechanosensitive hair bundle. Hair cells convert mechanical information contained within the temporal pattern of hair bundle deflections into electrical signals, which they transmit to the brain for interpretation.
Teacher Education Research
Authors: Menter Ian
Published: September 2017

Although teacher education has been recognized as a key aspect of educational policy and practice, especially over the past few decades, the research undertaken to inform policy is in many respects inadequate. Drawing on reviews of such research as has been undertaken in Europe, the United States, Australasia as well as other parts of the world, we can identify the key questions for teacher education researchers. These include such topics as the relationship between theory and practice in professional learning, the significance of partnerships between schools and higher education institutions, the relationship between preservice teacher education and ongoing professional learning and the nature of the assessment of beginning teachers.

Three approaches to teacher education research may be defined, and all of them are important in the quest for better understanding of the field. These three approaches are research in teacher education—mainly carried out by teacher education practitioners; research on teacher education—mainly carried out by education policy scholars; and research about teacher education—carried out by scholars in a range of disciplines and seeking to explore the wider social significance of teacher education. An exploration of each of these three approaches reveals that there is a serious dearth of large-scale and/or longitudinal studies that may be seen as genuinely independent and critical. This suggests that there is a large agenda for future teacher education research.
Ancient Steppe Nomad Societies
Authors: Kradin Nikolay
Published: September 2017

Throughout more than two millennia, the extensive droughty areas in East Asia were occupied by pastoral nomads. A long history exists of hybridity between steppe and agricultural areas. The ancient nomads had a specific pastoral economy, a mobile lifestyle, a unique mentality that assumed unpretentiousness and stamina, cults of war, warrior horsemen, and heroized ancestors that were reflected, in turn, in both their verbal oeuvre (heroic epos) and their arts (animal style). They established vast empires that united many peoples. In the descriptions of settled civilizations, the peoples of the steppe are presented as aggressive barbarians. However, the pastoral nomads developed efficient mechanisms of adaptation to nature and circumjacent states. They had a complex internal structure and created different forms of social complexity—from heterarchical confederations to large nomadic empires. The different forms of identity in pastoral societies (gender, age, profession, rank) are presented in this article. Special attention is given to how ethnic identity is formed from small groups. The ethnic history of the ancient nomads of East Asia is described, particularly for such pastoral societies as the Xiongnu, the Wuhuan, the Xianbei, and the Rouran.
Public Finance and Soft Budgets
Authors: Levaggi Rosella
Published: September 2017

The concept of soft budget constraint, describes a situation where a decision maker finds it impossible to keep an agent to a fixed budget. In healthcare it may refer to a (nonprofit) hospital that overspends, or to a lower government level that does not balance its accounts. The existence of a soft budget constraint may represent an optimal policy from the regulator point of view only in specific settings. In general, its presence may allow for strategic behavior that changes considerably its nature and its desirability. In this article, soft budget constraint will be analyzed along two lines: from a market perspective and from a fiscal federalism perspective.

The creation of an internal market for healthcare has made hospitals with different objectives and constraints compete together. The literature does not agree on the effects of competition on healthcare or on which type of organizations should compete. Public hospitals are often seen as less efficient providers, but they are also intrinsically motivated and/or altruistic. Competition for quality in a market where costs are sunk and competitors have asymmetric objectives may produce regulatory failures; for this reason, it might be optimal to implement soft budget constraint rules to public hospitals even at the risk of perverse effects. Several authors have attempted to estimate the presence of soft budget constraint, showing that they derive from different strategic behaviors and lead to quite different outcomes.

The reforms that have reshaped public healthcare systems across Europe have often been accompanied by a process of devolution; in some countries it has often been accompanied by widespread soft budget constraint policies. Medicaid expenditure in the United States is becoming a serious concern for the Federal Government and the evidence from other states is not reassuring. Several explanations have been proposed: (a) local governments may use spillovers to induce neighbors to pay for their local public goods; (b) size matters: if the local authority is sufficiently big, the center will bail it out; equalization grants and fiscal competition may be responsible for the rise of soft budget constraint policies. Soft budget policies may also derive from strategic agreements among lower tiers, or as a consequence of fiscal imbalances. In this context the optimal use of soft budget constraint as a policy instrument may not be desirable.
The Outer Space Treaty
Authors: Johnson Christopher Daniel
Published: September 2017

Negotiated at the United Nations and in force since 1967, the Outer Space Treaty has been ratified by over 100 countries and is the most important and foundational source of space law. The treaty, whose full title is “Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies,” governs all of humankind’s activities in outer space, including activities on other celestial bodies and many activities on Earth related to outer space. All space exploration and human spaceflight, planetary sciences, and commercial uses of space—such as the global telecommunications industry and the use of space technologies such as position, navigation, and timing (PNT), take place against the backdrop of the general regulatory framework established in the Outer Space Treaty.

A treaty is an international legal instrument which balances rights and obligations between states, and exists as a kind of mutual contract of shared understandings, rights, and responsibilities between them. Negotiated and drafted during the Cold War era of heightened political tensions, the Outer Space Treaty is largely the product of efforts by the United States and the USSR to agree on certain minimum standards and obligations to govern their competition in “conquering” space. Additionally, the Outer Space Treaty is similar to other treaties, including treaties governing the high seas, international airspace, and the Antarctic, all of which govern the behavior of states outside of their national borders. The treaty is brief in nature and only contains 17 articles, and is not comprehensive in addressing and regulating every possible scenario. The negotiating states knew that the Outer Space Treaty could only establish certain foundational concepts such as freedom of access, state responsibility and liability, non-weaponization of space, the treatment of astronauts in distress, and the prohibition of non-appropriation of celestial bodies. Subsequent treaties were to refine these concepts, and national space legislation was to incorporate the treaty’s rights and obligations at the national level.

While the treaty is the cornerstone in the regulation of activities in outer space, today the emergence of new issues that were not contemplated at the time of its creation, such as small satellites and megaconstellations, satellite servicing missions, the problem of space debris and the possibility of space debris removal, and the use of lunar and asteroid resources, all stretch the coherence and continuing adequacy of the treaty, and may occasion the need for new governance frameworks.
Propaganda in the History of US Foreign Relations
Authors: Belmonte Laura A.
Published: September 2017

From the revolutionary era to the post-9/11 years, public and private actors have attempted to shape U.S. foreign relations by persuading mass audiences to embrace particular policies, people, and ways of life. Although the U.S. government conducted wartime propaganda activities prior to the 20th century, it had no official propaganda agency until the Committee on Public Information (CPI) was formed in 1917. For the next two years, CPI aimed to generate popular support for the United States and its allies in World War I. In 1938, as part of its Good Neighbor Policy, the Franklin Roosevelt administration launched official informational and cultural exchanges with Latin America. Following American entry into World War II, the U.S. government created a new propaganda agency, the Office of War Information (OWI). Like CPI, OWI was disbanded once hostilities ended. But in the fall of 1945, to combat the threats of anti-Americanism and communism, President Harry S. Truman broke with precedent and ordered the continuation of U.S. propaganda activities in peacetime. After several reorganizations within the Department of State, all U.S. cultural and information activities came under the purview of the newly created U.S. Information Agency (USIA) in 1953. Following the dissolution of USIA in 1999, the State Department reassumed authority over America’s international information and cultural programs through its Office of International Information Programs.
Domestic Workers in U.S. History
Authors: May Vanessa
Published: September 2017

Domestic work was, until 1940, the largest category of women’s paid labor. Despite the number of women who performed domestic labor for pay, the wages and working conditions were often poor. Workers labored long hours for low pay and were largely left out of state labor regulations. The association of domestic work with women’s traditional household labor, defined as a “labor of love” rather than as real work, and its centrality to southern slavery, have contributed to its low status. As a result, domestic work has long been structured by class, racial, and gendered hierarchies. Nevertheless, domestic workers have time and again done their best to resist these conditions. Although traditional collective bargaining techniques did not always translate to the domestic labor market, workers found various collective and individual methods to insist on higher wages and demand occupational respect, ranging from quitting to “pan-toting” to forming unions.
Radicalism in America after 1945
Authors: Cook Vaneesa
Published: September 2017

Radicalism in the United States since 1945 has been varied, complex, and often fragmented, making it difficult to analyze as a coherent movement. Communist and pro-Soviet organizations remained active after World War II, but a proliferation of noncommunist groups in the 1940s and 1950s, formed by those disillusioned by Marxist theory or the Soviet Union, began to chart a new course for the American Left. Eschewing much of the previous focus on labor, the proletariat, and Marxist doctrine, American postwar radical organizations realigned around humanist values, moral action, democracy, and even religion, with tenuous connections to Marxism, if any. The parameters of postwar radical moral theory were not always clearly defined, and questions of strategy and vision caused frequent divisions among activists. Nonetheless, claims of individual dignity and freedom continued to frame left radicalism into the late 20th century, emphasizing identity politics, community-building initiatives, and cultural expression in the streets of U.S. cities and the halls of academia. The presidential campaign of Bernie Sanders in 2016 helped revitalize leftist rhetoric on the national stage with its calls for racial and economic equality on moral terms.
Social Christianity in America
Authors: Carter Heath W.
Published: September 2017

Social Christianity is a heterogeneous tradition that has been cultivated by a diverse array of American Christians who shared in common an intuition that the source of social problems is more exterior than interior to the individual. Social gospelers have contended, in word and in deed, that sin infects not only individuals but also systems and structures; that salvation is not only personal but also societal; and that therefore participation in the struggle for a more just society is, for Christians, not so much optional as essential. This distinctly modern tradition first emerged in the antebellum period, but was overshadowed by older, benevolent, and bourgeois modes of reform until the early 20th century, when it gained a stronger foothold in both the institutional churches and the worlds beyond their walls. Social Christianity’s influence was never more formidable than during the New Deal era. It was during those pivotal decades, which saw the rise of a robust welfare state as well as of massive, faith-infused labor and civil rights movements, that social gospelers left their most lasting mark on American society. In the late 20th century and early 21st centuries, the tradition’s influence would decline precipitously, in no small part due to the success of a multifaceted backlash against social gospel ideas and movements. The rise of the modern right signaled, for social gospelers of all different kinds, a return to the wilderness.
Space and Church–State Controversies in America
Authors: Blakeman John C.
Published: September 2017

Issues of church and state are an important element of American religious history and politics. Church–state issues frequently concern the extent of government regulation over religious groups and individuals, and they address fundamental issues, from the constitutional limits on government regulation of religiously inspired conduct to state and local government zoning of religious congregations and property owned and used by religious groups.

Space is often a part of church–state issues. Beginning with early debates over religious liberty in the Puritan colonies in the 1600s, and again during the American Revolution and framing of the U.S. Constitution between 1775 and 1790, spatial conceptions of the proper role between church and state, and between government and religion, are prominent. Two fundamental thinkers on American religious liberty, the Puritan minister Roger Williams and the constitutional framer James Madison, illustrate this dimension of church–state relations.

Disputes over space, church, and state are often resolved by the court system through litigation, or through the political process. Such disputes often stem from government policies and regulations that affect how a congregation or religious group uses its own property. For instance, zoning and other municipal ordinances may affect and burden how a religious group uses its property and even interfere with a group’s religious mission. Religious beliefs may compel a congregation to use its property to engage in charitable works, yet it may be prohibited from doing so due to government regulations on how its property can be used. Or when a congregation seeks to expand its facilities to attract more members, or even build a new worship center elsewhere, it may encounter government policies that regulate its ability to do so.

Other disputes over space arise when government regulation of public property affects a religious group’s use of it. For example, some religious groups stake a sacred claim to land or other space owned by the government. However, government regulations concerning how the land is used might interfere with a group’s ability to act upon its sacred beliefs. In some cases, religious groups may seek to use public property for religious purposes and activities, such as the display of a religious symbol or for proselytizing to the public, and government policies may prevent that in order to avoid violating the Constitution’s ban on government establishment of religion in the First Amendment.

A final view of space and church–state issues is more conceptual and less grounded in tangible space, land, and property. Some religious groups seek a more abstract, intangible space between them and government regulation. Groups such as the Old Order Amish that seek to separate from the world will erect a buffer space between themselves and government regulation, so as to preserve the purity, and sanctity, of their way of life that is inextricably linked to their specific religious beliefs.
Social Capital and Natural Hazards Governance
Authors: Aldrich Daniel P. , Meyer Michelle A. , Page-Tan Courtney M.
Published: September 2017

The impact of disasters continues to grow in the early 21st century, as extreme weather events become more frequent and population density in vulnerable coastal and inland cities increases. Against this backdrop of risk, decision-makers persist in focusing primarily on structural measures to reduce losses centered on physical infrastructure such as berms, seawalls, retrofitted buildings, and levees. Yet a growing body of research emphasizes that strengthening social infrastructure, not just physical infrastructure, serves as a cost-effective way to improve the ability of communities to withstand and rebound from disasters. Three distinct kinds of social connections, including bonding, bridging, and linking social ties, support resilience through increasing the provision of emergency information, mutual aid, and collective action within communities to address natural hazards before, during, and after disaster events. Investing in social capital fosters community resilience that transcends natural hazards and positively affects collective governance and community health.

Social capital has a long history in social science research and scholarship, particularly in how it has grown within various disciplines. Broadly, the term describes how social ties generate norms of reciprocity and trust, allow collective action, build solidarity, and foster information and resource flows among people. From education to crime, social capital has been shown to have positive impacts on individual and community outcomes, and research in natural hazards has similarly shown positive outcomes for individual and community resilience. Social capital also can foster negative outcomes, including exclusionary practices, corruption, and increased inequality. Understanding which types of social capital are most useful for increasing resilience is important to move the natural hazards field forward.

Many questions about social capital and natural hazards remain, at best, partially answered. Do different types of social capital matter at different stages of disaster—e.g., mitigation, preparedness, response, and recovery? How do social capital’s effects vary across cultural contexts and stratified groups? What measures of social capital are available to practitioners and scholars? What actions are available to decision-makers seeking to invest in the social infrastructure of communities vulnerable to natural hazards? Which programs and interventions have shown merit through field tests? What outcomes can decision-makers anticipate with these investments? Where can scholars find data sets on resilience and social capital? The current state of knowledge about social capital in disaster resilience provides guidance about supporting communities toward more resilience.
Impact of Climate Change on Flood Factors and Extent of Damages in the Hindu Kush Region
Authors: Rahman Atta-ur , Mahmood Shakeel , Dawood Mohammad , Rahman Ghani , Chen Fang
Published: September 2017

This chapter analyzes the impacts of climate change on flood factors and extent of associated damages in the Hindu Kush (HK) region. HK mountains system is located in the west of the Himalayas and Karakorum. It is the greatest watershed of the River Kabul, River Chitral, River Panjkora, and River Swat in the eastern Hindu Kush and River Amu in western Hindu Kush. The Hindu Kush system hosts numerous glaciers, snow-clad mountains, and fertile river valleys; it also supports large populations and provides year-round water to recharge streams and rivers. The study region is vulnerable to a wide range of hazards including floods, earthquakes, landslides, desertification, and drought. Flash floods and riverine floods are the deadliest extreme hydro-meteorological events. The upper reaches experience characteristics of flash flooding, whereas the lower reach is where river floods occur. Flash floods are more destructive and sudden. Almost every year in summer, monsoonal rainfall and high temperature join hands with heavy melting of glaciers and snow accelerating discharge in the river system. In the face of climate change, a significant correlation between rainfall patterns, trends in temperature, and resultant peaks in river discharge have been recorded. A rising trend was found in temperature, which leads to early and rapid melting of glaciers and snow in the headwater region. The analysis reveals that during the past three decades, radical changes in the behavior of numerous valley glaciers have been noted. In addition, the spatial and temporal scales of violent weather events have been growing, since the 1980s. Such changes in water regimes including the frequent but substantial increase in heavy precipitation events and rapid melting of snow in the headwater region, siltation in active channels, excessive deforestation, and human encroachments onto the active flood channel have further escalated the flooding events. The HK region is beyond the reach of existing weather RADAR network, and hence forecasting and early warning is ineffective. Here, almost every year, the floods cause damages to infrastructure, scarce farmland, and sources of livelihood.
History and Assessment of the Intergovernmental Platform on Biodiversity and Ecosystem Services
Authors: Granjou Céline , Arpin Isabelle
Published: September 2017

The recent implementation of the IPBES is a major cornerstone in the transformation of the international environmental governance in the early 21st century. Often presented as “the IPCC (Intergovernmental Panel on Climate Change) for biodiversity,” the IPBES aims to produce regular expert assessments of the state and evolution of biodiversity and ecosystems at the local, regional, and global levels. Its creation was promoted in the 1990s by biodiversity scientists and NGOs who increasingly came to view the failure of achieving effective conservation of nature as the consequence of the gap between science and policy, rather than of a lack of knowledge. The new institution embodies an approach to nature and nature conservation that results from the progressive evolution of international environmental governance, marked by the notion of ecosystem services (i.e., the idea that nature provides benefits to people and that nature conservation and human development should be thought of as mutually constitutive). The IPBES creation was entrusted to the United Nations Environment Programme (UNEP). Social environmental studies accounted for the genesis and organization of the IPBES and paid special attention to the strong emphasis put by IPBES participants on principles of openness and inclusivity and on the need to consider scientific knowledge and other forms of knowledge (e.g. traditional ecological knowledge) on an equal footing. Overall the IPBES can be considered an innovative platform characterized by organizations and practices that foster inclusiveness and openness both to academic science and indigenous knowledge as well as to diverse values and visions of nature and its relationship to society. However, the extent to which it succeeded in putting different biodiversity values and knowledge on an equal footing in practice has varied and remains diversely appreciated by the literature.

BACKGROUND

Antihypertensive treatment improves echocardiographic parameters of hypertensive target organ damage in stage II hypertension, but less is known about the effects in stage I hypertension.

METHODS

In a cohort study nested in the randomized double-blind trial PREVER-treatment, 2-dimensional echocardiograms were performed in 110 individuals, aged 54.8 ± 7.9 years-old, with stage I hypertension at baseline and after 18 months of treatment with chlorthalidone/amiloride or losartan.

RESULTS

At baseline, 66 (60%) participants had concentric remodeling. After antihypertensive treatment, systolic (SBP) and diastolic blood pressure (BP) were reduced from 141/90 to 130/83 mm Hg (P = 0.009). There was a significant reduction in left ventricular (LV) mass (LVM) index (82.7 ± 17.1 to 79.2 ± 17.5 g/m2; P = 0.005) and relative wall thickness (0.45 ± 0.06 to 0.42 ± 0.05; P < 0.001), increasing the proportion of participants with normal LV geometry (31% to 49%, P = 0.006). Left atrial (LA) volume index reduced (26.8 ± 7.3 to 24.9 ± 6.5 ml/m2; P = 0.001), and mitral E-wave deceleration time increased (230 ± 46 to 247 ± 67 ms; P = 0.005), but there was no change in other parameters of diastolic function. LVM reduction was significantly higher in the 2 higher tertiles of SBP reduction compared to the lower tertile.

CONCLUSIONS

Treatment of patients with stage I hypertension for 18 months promotes favorable effects in the LA and LV remodeling. This improvement in cardiac end-organ damage might be associated with reduction of long term clinical consequences of hypertensive cardiomyopathy, particularly heart failure with preserved ejection fraction.
Modelling growth and reproduction of Antarctic krill, Euphausia superba, based on temperature, food and resource allocation amongst life history functions

Published: September 2017

Estimates of productivity of Antarctic krill, Euphausia superba, are dependent on accurate models of growth and reproduction. Incorrect growth models, specifically those giving unrealistically high production, could lead to over-exploitation of the krill population if those models are used in setting catch limits. Here we review available approaches to modelling productivity and note that existing models do not account for the interactions between growth and reproduction and variable environmental conditions. We develop a new energetics moult-cycle (EMC) model which combines energetics and the constraints on growth of the moult-cycle. This model flexibly accounts for regional, inter- and intra-annual variation in temperature, food supply, and day length. The EMC model provides results consistent with the general expectations for krill growth in length and mass, including having thin krill, as well as providing insights into the effects that increasing temperature may have on growth and reproduction. We recommend that this new model be incorporated into assessments of catch limits for Antarctic krill.

The hemibiotrophic pathogen Colletotrichum orbiculare preferentially expresses a necrosis and ethylene-inducing peptide 1 (Nep1)-like protein named NLP1 during the switch to necrotrophy. Here, we report that the constitutive expression of NLP1 in C. orbiculare blocks pathogen infection in multiple Cucurbitaceae cultivars via their enhanced defense responses. NLP1 has a cytotoxic activity that induces cell death in Nicotiana benthamiana. However, C. orbiculare transgenic lines constitutively expressing a mutant NLP1 lacking the cytotoxic activity still failed to infect cucumber, indicating no clear relationship between cytotoxic activity and the NLP1-dependent enhanced defense. NLP1 also possesses the microbe-associated molecular pattern (MAMP) sequence called nlp24, recognized by Arabidopsis thaliana at its central region, similar to NLPs of other pathogens. Surprisingly, inappropriate expression of a mutant NLP1 lacking the MAMP signature is also effective for blocking pathogen infection, uncoupling the infection block from the corresponding MAMP. Notably, the deletion analyses of NLP1 suggested that the C-terminal region of NLP1 is critical to enhance defense in cucumber. The expression of mCherry fused with the C-terminal 32 amino acids of NLP1 was enough to trigger the defense of cucurbits, revealing that the C-terminal region of the NLP1 protein is recognized by cucurbits and, then, terminates C. orbiculare infection.
