Russian Epistolary Writing from the Middle Ages to the Turn of the 19th Century
Authors: Rubin-Detlev Kelsey
Published: May 2021

Epistolary writing is probably not the first thing that comes to mind when one thinks of Russia’s contributions to world literature—despite the landmark theoretical work of the Russian Formalists in the 1920s, which presciently highlighted the literary interest of the letter and paved the way for the explosion of scholarship on epistolarity in the West in the late 20th century. Nevertheless, the epistolary mode has accompanied and helped to shape Russian literature since its beginnings. For many centuries, epistolary texts offered a space for unusually vivid expressions of unique authorial selves while at the same time encouraging self-conscious play with literary form. Within a century of the adoption of writing by the Eastern Slavs in the mid-10th century, people across the social spectrum were writing letters on birchbark; in the Middle Ages, when Russian writing aimed above all to teach religious truths and build a Christian community, epistolary forms facilitated the creation of exceptionally individualized representations of the author(s) and/or addressee(s) of letters. In the early modern period, epistolary forms played an important role in the development of literature, since they were among the first types of text to be recognized as distinct genres. The late 18th and early 19th centuries witnessed the heyday of the European-style familiar letter, which became a primary literary genre through which elite writers maintained emotional, social, and professional ties, projected a sophisticated self-image, and wrestled with the implications of Russia’s participation in Western cultural life.
The Stationers’ Company, 1403–1775: London’s Book Trade Guild
Authors: Gadd Ian
Published: May 2021

The Stationers’ Company is one of Britain’s most important cultural institutions. Founded in 1403, it oversaw the regulation of the London’s book trades for several centuries. From the mid-16th century to the end of the 17th, the Company maintained a near-national monopoly over the technology and craft of printing; during that same period, almost every important English printer and publisher belonged to it, and the vast majority of books published in England were printed and sold by its members. It played a crucial role in the development and implementation of modern Anglo-American copyright law, establishing in the 1550s a ‘Register’ for the recording of publishing rights that was still being used in the early decades of the 20th century. Six centuries on, the Company continues to retain strong ties to the printing, publishing, and allied industries.

The Company was — and remains — one of the dozens of livery companies that historically regulated London’s crafts and trades. Its national powers, granted to it by the crown in 1557, were exceptional but not unique, and effectively lapsed in 1695. It had oversight of training, labor, wages, and prices, and regularly arbitrated members’ disputes; it also provided vital welfare and social functions for its members and their families. During the early modern period, it was frequently cited in state decrees and legislation that sought to regulate the publication of printed material, but it was never the active censoring body that subsequent scholarship has often claimed. Despite weakening powers from the late 17th century, the Company flourished into the Victorian era, in large part due to its distinctive publishing venture, the English Stock, whose interests it fiercely defended. In 1937 it formally incorporated newspaper makers into its ranks, becoming the Worshipful Company of Stationers and Newspaper Makers. The Company’s hall, which houses its archive, is located off Ludgate Hill in central London.
Natural Experiments in Business Research Methods
Authors: Withers Michael C. , Li Chi Hon
Published: May 2021

Causal identification is an important consideration for organizational researchers as they attempt to develop a theoretical understanding of the causes and effects of organizational phenomena. Without valid causal identification, insights regarding organizational phenomena are challenging given their inherent complexity. In other words, organizational research will be limited in its scientific progression. Randomized controlled experiments are often suggested to provide the ideal study design necessary to address potential confounding effects and isolate true causal relationships. Nevertheless, only a few research questions lend themselves to this study design. In particular, the full randomization of subjects in the treatment and control group may not be possible due to the empirical constraints. Within the strategic management area, for example, scholars often use secondary data to examine research questions related to competitive advantage and firm performance. Natural experiments are increasingly recognized as a viable approach to identify causal relationships without true random assignment. Natural experiments leverage external sources of variation to isolate causal effects and avoid potentially confounding influences that often arise in observational data. Natural experiments require two key assumptions—the as-if random assignment assumption and the stable unit treatment value assumption. When these assumptions are met, natural experiments can be an important methodological approach for advancing causal understanding of organizational phenomena.
Intergovernmental Conference: Three Case Studies of EC/EU Institution Building
Authors: Plechanovová Běla
Published: May 2021

Intergovernmental conference (IGC) within the European integration context is a vehicle for institutional change. Based on the majority decision in the Council, the representatives of member states’ governments convene to debate proposals for amendments to the founding treaties of the European Union (EU) and make decisions on the agreed changes, which are then subject to the ratification process in the member countries according to their constitutional requirements. This procedure was used for almost all treaty revisions until the Treaty of Lisbon in 2007 changed the rules. An ordinary revision procedure was introduced that assumes a role for the Convention to draft changes to the treaties, while keeping the IGC as a next step in the process. A simplified revision procedure was introduced for making adjustments to the internal policies and actions of the EU according to the Treaty on the Functioning of the EU, thus replacing the IGC by a unanimous decision of the European Council. The Merger Treaty of 1965, the Single European Act in 1986, and the Amsterdam Treaty in 1997 represent distinct steps in shaping the perception of the role of the IGC as an institution in the political process within the European Communities and the EU.
Bureaucracies and Policy Ideas
Authors: Bach Tobias
Published: May 2021

The idea of a clear separation between policymaking and implementation is difficult to sustain for policy bureaucracies in which public officials have “policy work” as their main activity. A diverse body of scholarship indicates that bureaucrats may enjoy substantial levels of discretion in defining the nature of policy problems and elaborating on policy alternatives. This observation raises questions about the conditions under which bureaucratic policy ideas make their way into authoritative policy decisions, the nature of those policy ideas, and how bureaucratic policymaking has evolved. A main point is that bureaucratic policy ideas are developed in a political context, meaning that bureaucrats have to anticipate that political decision makers will eventually have to endorse a policy proposal. The power relations between politicians and bureaucrats may, however, vary, and bureaucrats may gain the upper hand, which is likely if a bureaucracy is professionally homogenous and able to develop a coherent policy idea. Another perspective concerns the origins of policy ideas. There is limited evidence for individual-level explanations of policy ideas, according to which bureaucrats pursue exogenously defined preferences to maximize their own utility. A competing organizational perspective, which considers policy preferences as the result of organizational specialization, the development of local rationalities, and the defense of organizational turf, stands out as a more plausible explanation for the origins of bureaucratic policy ideas. The policymaking role, and thereby the importance of bureaucratic policy ideas, is being challenged by the rise of ministerial advisors, agencification, and better regulation reforms. Those developments have the potential to change the substance of bureaucratic policy ideas, but they may also generate strategic behavior, which should be of interest to scholars of the politics of bureaucracy.
Public Administration in Central and Eastern Europe
Authors: Mazur Stanisław
Published: May 2021

In the early 1990s, the Central and Eastern European countries (CEE countries) saw the collapse of communist regimes and an unprecedented political and economic transformation that resulted in the establishment of democratic, law-governed states and market economies.

Administrative reforms, which became an important milestone in this transformation, were considerably influenced both by administrative legacies predominant in the countries and by the Europeanization processes associated with their accession to the European Union. The administrative legacies, which combine elements of various traditions (e.g., German, Napoleonic, and Anglo-American) are still strongly affected by what is left of the communist era. Conversely, the impact of Europeanization processes on public administrations in CEE countries has proved to be much weaker than initially expected.

The process of building a professional and apolitical civil service in CEE countries has been plagued by discontinuity and inconsistency, owing to the specific administrative culture of the region, the weakening pressure to modernize EU institutions, and the consequences of the 2008 financial crisis, as well as growing populist tendencies in the region. All these factors encouraged the belief that political control over public administration needs to be tightened in order for the effectiveness and quality of governance mechanisms to be improved.

The quality of governance and public management varies widely across the CEE countries. What they have in common—at least to some extent—is the fairly high dynamics of change, including the reversal of the effects of previously implemented reforms. The latter factor may be interpreted as a search for country-specific reform paths, partly due to disappointment with the values and models prevailing in Western Europe, and somewhat as a consequence of growing populist tendencies in the region.
Cognitive Implications of Bilingualism
Authors: Bialystok Ellen
Published: May 2021

There has been an enormous expansion during the early 21st century in psychological research on topics relating to bilingualism, paralleling developments in other fields of psychology that investigate the interface between experience and the mind. These issues reflect the view that brains and minds remain plastic and can be modified by experience throughout life. In the case of bilingualism, a central question is whether bilingual experience modifies cognitive systems in general, and more specifically, if it improves cognitive ability and executive functioning. The research has produced contradictory results, in some cases supporting a beneficial effect on cognition and in some cases indicating no effect. Crucially, there is essentially no research that indicates that bilingualism is associated with poorer cognitive outcomes than found for those who are monolingual. Studies showing a positive role for bilingualism on cognitive outcomes have been reported across the life span. Early research with children in the first half of the 20th century concluded that bilingualism was detrimental to children’s intelligence, a claim that has been thoroughly refuted and replaced with evidence identifying specific cognitive processes that are more advanced in bilingual than in monolingual children. A few studies have even reported better attentional control, the foundation of executive functioning, for infants in the first year of life being raised in bilingual homes than for those in monolingual environments. Young adults frequently show no behavioral differences between language groups when performing executive function tasks, but neuroimaging (electrophysiology or brain imaging) consistently indicates that monolinguals and bilinguals use different brain regions and different degrees of effort to perform these tasks. The clearest language group differences, however, occur in older age where evidence for cognitive reserve from bilingualism is found most clearly in the postponement of symptoms of dementia. Therefore, it is necessary to analyze the factors that mediate these effects, notably, the nature of bilingual experience and the details of the cognitive task being used. The conclusion is that bilingualism is complex but there is evidence for a consistent and systematic impact on cognitive systems.
Emotions at Work
Authors: Ashkanasy Neal M. , Bialkowski Agata
Published: May 2021

Beginning in the 1980s, interest in studying emotions in organizational psychology has been on the rise. Prior to 2003, however, researchers in organizational psychology and organizational behavior tended to focus on only one or two levels of analysis. Ashkanasy argued that emotions are more appropriately conceived of as spanning all levels of organizational analysis, and introduced a theory of emotions in organizations that spans five levels of analysis. Level 1 of the model refers to within-person temporal variations in mood and emotion, which employees experience in their everyday working lives. Level 2 refers to individual differences in emotional intelligence and trait affectivity (i.e., between-person emotional variables). Level 3 relates to the perception of emotions in dyadic interactions. Level 4 relates to the emotional states and process that take place between leaders and group members. Level 5 involves organization-wide variables. The article concludes with a discussion of how, via the concept of emotional intelligence, emotions at each level of the model form an integrated picture of emotions in organizational settings.
Criminal Governance in Latin America
Authors: Mantilla Jorge , Feldmann Andreas E.
Published: May 2021

Criminal governance understood as the regulation of social order, including informal or illegal economies through the establishment of formal and informal institutions that replace, complement, or compete with the state and distribute public goods (e.g., social services, justice, and security) is an expanding area of inquiry in the field of criminology. This analysis, which centers on Latin America, a region beset by this problem, unpacks specific dimensions of this concept including the overlap between the state and criminal orders, the relationship between violence and consent, and violence management through selective forms of enforcement. In so doing it sheds light on how changes in the architecture of governance of many underprivileged communities across the world, but especially in the Global South, is affecting in critical ways the lives and wellbeing of millions of individuals. The discussion underscores the need to reinforce interdisciplinary work linking criminology and other disciplines (e.g., political science, sociology, law, anthropology) as a way to enhance our understanding of the profound impact that criminal governance orders have on the political and social dimensions of contemporary societies.
Race and Police Misconduct Cases
Authors: Headley Andrea M. , Blount-Hill Kwan-Lamar
Published: May 2021

Racial disparities abound in policing, and police misconduct is no exception. Literature on race and police misconduct can be categorized into three sub-themes: race and (a) civilian complaints about police misconduct, (b) public perceptions about police misconduct, and (c) officer perceptions of police misconduct. Racial disparities are apparent in the resolution of civilian complaints, and in perceptions of the ubiquity and severity of police misconduct. People of color may not always view accountability systems as legitimate or feel comfortable using formal complaint processes as a means of resolve. Officers of color report being disadvantaged by internal compliant processes, observing more misconduct than do their White peers, and feeling less comfortable with informal codes of silence. All officers generally rate misconduct involving use of force against civilians of color as more serious when compared to similar incidents involving white individuals. Officers of color, in particular, are more likely to admit beliefs that police treat people differently based on race and income. As with police outcomes more generally, race-based disparities in measures of misconduct likely persist due to a combination of complex and interconnected individual-, institutional-, and societal-level factors. Further research is needed. Lack of comprehensive reporting mechanisms nationwide poses challenges for scholars studying misconduct. There needs to be a greater diversity of methods used to study misconduct, including qualitative methods, and more evaluative studies of the variety of policies proposed as solutions to misconduct. The contexts of misconduct research must also be expanded beyond the United States and the Global North/West to offer international and comparative insights.
Provocations, Perspectives, and Possibilities of Chicana/Latina Feminist Pedagogies
Authors: Diaz-Kozlowski Tanya
Published: May 2021

Chicana/Latina feminist thought and pedagogies offer interdisciplinary contributions that reimagine family, community, liberation, teaching, and learning rooted in de-colonial praxis. Chicana/Latina feminist thought and pedagogies have cultivated theoretical, methodological, and epistemological cartographies that map questions such as: what are the evolving conditions that shape the oppression Chicanas face in their daily lives?; how do Chicanas cultivate multiple subjectivities that strive for embodied wholeness rather than partiality?; in what ways can intersectionality as a theory of oppression not difference dismantle systems of privilege and inequality that are pervasive within institutions such as education, healthcare, the prison industrial complex, the military, religion, families, and mass media?; and how can theories of the flesh which emerge through the lived experiences of Chicanas’ lives offer new pathways to coalition building, activism, scholarship, and teaching and learning that remain bridged to equity, and to justice as praxis not place? Chicana feminist thought includes themes of the history and material conditions of Chicanas as the basis for feminist consciousness, reclaiming malinchismo and marianismo, sexuality (Chicanas as sexual subjects), a commitment to political action, coalition building and recognition of difference among Chicanas, and challenging the vendida logic within Chicano culture.

Chicana/Latina feminist pedagogies are insistent that everyday experiences of Chicanas are worth studying because they serve as key sources of knowledge that are necessary to theorize new de-colonial visions of life, family, labor, community, and education. Chicana/Latina feminist pedagogies are multidisciplinary in their approach and are culturally specific ways of organizing teaching and learning in informal sites such as the home and community, ways that embrace Chicana ways of knowing and creating knowledge that point to schooling spaces as full of creativity, agency, movement, and coalition building.
Autonomy and Higher Education in Africa
Authors: Divala Joseph Jinja
Published: May 2021

In an age of increasing automation, what separates a human process from automation is the flexibility and autonomy human beings have and operate with in real time. Despite the fact that humans are driven by autonomy to operate and process things, such autonomy is often taken for granted and at times is only alluded to as an afterthought. But what is autonomy? How does autonomy make a person’s actions differ from those of an automated, inanimate being? Autonomy is often talked about as synonymous with freedom. This basic characterization partially responds to the fuller meaning of autonomy. This is the case when freedom is confined to freedom from, which is most often how this concept is used. Autonomy as an internal drive to determine one’s actions necessarily combines both freedom from as well as freedom to.

It is no simpler to discuss or pin down “autonomy” within the context of university traditions and practices. The variability of practices and traditions has resulted in different formulations of what autonomy would mean in a university context. Similar to what determines autonomy as concept at an individual personal level, the autonomy of the academic or the academic institution, in this case the university, also brings forth specific understandings of life and its processes.

Just as autonomy cannot exist without any forms of life to exercise it, the conditions in African universities today mean that neither traditional communitarian positions nor liberal conceptions are necessarily amenable to the progress of autonomy within these institutions. A neo-communitarian position serves as a more tenable concept that can represent forms of autonomy that are neither alienating nor too deterministic.
Multilingualism and Identity in Hong Kong Education After 1997
Authors: Gu Michelle Mingyue , Tong Ho Kin
Published: May 2021

Multilingual settings are regarded as ideologically, culturally, linguistically, and ethnically diverse social contexts where tensions exist among different groups and individuals, and in which language users’ multilingual competence can be utilized as repertoire for communicative, identification, and learning purposes. Multilingualism and identity have been widely explored from different theoretical orientations in diverse educational settings. The major research findings from the postmodernist perspective reflect that (a) identity, reflecting an individual’s relationship with the external environment, is dynamic, multiple, and fluid; (b) individuals’ identities are continuously shaped in multilingual interactions, and the multilingual settings provide affordance for the language users to identify themselves through the lens of cultural memories, embodied history, subjectivity of themselves and others, during which the new identities and relationships are established; and (c) the multilingual speakers can shape the multilingual settings through negotiating power relations between languages as well as cultures, and modifying as well as reconstructing social discourses. As such, the exploration of multilingualism and identity, and their complex interplay with educational discourse, history, and sociopolitical realities, have both theoretical significance and practical implications for transferring diversity into recourses and constructing new spaces and opportunities for identity, language, and education in an era of increasing hybridity and mobility.
The Judicialization of American Education
Authors: Blokhuis J.C. , Curren Randall
Published: May 2021

Judicialization is the term most commonly used to describe the supervening authority of the courts in virtually every sphere of public life in liberal democratic states. In the United States, where judicialization is most advanced, political and administrative decisions by agencies and officials at every level of government are subject to constitutional scrutiny, and thus to the oversight and substituted decision-making authority of unelected members of the federal judiciary.

The judicialization of American education is associated with the judicial review of administrative decisions by public school officials in lawsuits filed in the federal courts by or on behalf of students alleging due process and other Constitutional rights violations. So defined, the judicialization of American education has been facilitated by a number of legal and social developments in the Civil Rights Era, including the ascription of limited Constitutional rights to minors in public schools, the expansion of government agency liability, and the ensuing proliferation of lawsuits under Section 1983.

Judicialization has been criticized for subjecting routine administrative decisions to complex and costly procedural regimentation, for distorting social relations by subjecting them to legal oversight, and for flooding the courts with frivolous lawsuits. The causes and outcomes of the judicialization of American education present a complex and mixed picture, however. The U.S. Office of Economic Opportunity’s Legal Services Program has played a central role in judicialization by providing legal resources to confront racial injustice in the punishment of students and in school funding.
Praise in Education
Authors: Benson-Goldberg Sofia , Erickson Karen A.
Published: May 2021

Classroom teachers receive myriad advice about how best to manage students’ attention, interest, and behavior. Praise is often highlighted as a specific tool that teachers should use to reinforce both behavior and learning. Since praise statements are positive evaluations of students’ performance or behavior, they are thought to be an encouraging, motivating, and affirming tool for reinforcement. So strong is this belief in praise that many interventions have been created to increase the rate of praise teachers offer in both general and special education classrooms. These interventions, when evaluated narrowly, appear to be successful because increased rates of teacher praise result in increased student compliance. However, when evaluated more broadly, research shows that praise statements have long-lasting, often negative impacts on students that may inadvertently negatively impact academic achievement. Therefore, despite the seemingly positive benefits of praise, its role in learning and development remains unsettled.
Moral Education and Technology
Authors: Farber Paul , Metro-Roland Dini
Published: May 2021

Moral education and technology seem to represent two fundamentally different kinds of concern and domains of inquiry. But these domains are fused in educational practice. Teaching as a fundamental human endeavor and form of activity has been a central component of human cultural evolution and regeneration from the earliest human social groupings. As a distinctive form of activity, teaching braids together ethical and instrumental norms and values. The modern, global institution of schooling has added layers of institutional support, constraint, and governance on the teaching it structures as well as increased scrutiny of the ethical and instrumental values in play; schooling is in effect a kind of moral technology for advancing certain norms and values in an efficient way. At present, technological developments with modern society make possible new forms of teaching and learning that likewise warrant scrutiny as they impact the ethical and instrumental ends of teaching and instructional practices today.
Education and Cultural Navigation for Children in Refugee Resettlement Contexts
Authors: Sung Jieun , Wahl Rachel
Published: May 2021

According to the United Nations High Commissioner for Refugees (UNHCR), over half of the 25.4 million refugees worldwide are children under the age of 18. Given the instability and precariousness that displaced persons may experience, the provision of education for these children is of significant concern. Interaction between the culture of the host society and the cultures of immigrants, including experiences related to education, is a key aspect of transitioning to a new national environment. These interactions may be particularly salient for displaced populations, considering the particular circumstances and life trajectories that are characteristic of refugees and generally not shared by other immigrant groups. Empirical research on refugee children’s education in resettlement countries highlights the significance of acculturative processes for experiences and outcomes of schooling, as well as the importance of educational settings in facilitating cultural interaction—that is, the interlocking and complementary nature of acculturation and education. Education and cultural navigation are linked in significant ways, such that even as education facilitates the cultural exposure and integration of newcomer individuals to a receiving society, acculturation itself is associated with adaptation to the school context and academic experiences. In other words, educational and acculturative processes can facilitate and reinforce each other. Additional research that examines more specifically processes of cultural navigation by refugee children in particular can further illuminate the factors that shape their experience of education in resettlement contexts.
Oil Industrialization in the Middle East
Authors: Shafiee Katayoun
Published: May 2021

The building of the global oil industry in the Middle East served as the occasion for one of the largest political projects of technical and economic development in the modern world. Scholarship has long associated an abundance of natural resources such as oil with autocracy in the Middle East while overlooking the sociotechnical ways in which oil operations were built with political consequences for the shape of the state and the international oil corporations. The early period of oil development was marked by oil abundance up to World War I, when demand for oil started to increase rapidly with the invention of the internal combustion engine. The cheapest source of production was in the Middle East. From the perspective of the largest transnational oil corporations to emerge in this period, the energy system needed to be built in a way that demand and overabundance were managed. Oil industrialization enabled the production and large-scale consumption of this new and abundant source of energy but was also connected with striking oil workers and controlling or blocking processes of industrialization in rival sectors such as the coal and the chemicals industries. In the first three decades of the 20th century, the process was made possible through the building of an international oil economy that took the form of production quotas and consortium agreements to restrict new oil discoveries in the Middle East. Oil industrialization projects intensified after World War II due to a flood of petrodollars into OPEC countries such as Iran and Saudi Arabia. Rising oil revenues and sovereign control achieved through oil nationalization triggered the execution of five-year development plans of industrial and infrastructural expansion. The birth of environmental activism in the 1960s–1970s coincided with the end of oil abundance and the fear of the planet’s destruction, spurring the passage of legislation to place limits on the hydrocarbon economy in which the machinery of oil industrialization had thrived.
The Sogdian Merchant Network
Authors: Yoshida Yutaka
Published: May 2021

Sogdians were Iranian-speaking people, and their land, Sogdiana, consisted of several oasis states located along the river Zarafshan. The leading cities were Samarkand and Bukhara. It constituted a satrapy of the Achaemenid empire, and later it was under the control of neighboring superpowers, such as Kushan and the Western Turks. However, until it was conquered by the Arabs in the 8th century it was able to enjoy a degree of independence. During this period, in particular during the 6th to 8th centuries, Sogdians played a leading role as traders along the overland Silk Road. Their trade network was extended not only to China but also to Mongolia, Tibet, India, Persia, Byzantium, and East Europe. Some of the commodities retailed by them are found in the documents of the 7th century discovered in Turfan; silk thread, horses, slaves, gold, silver, medicine, fragrance, turmeric, ammonium chloride, and so on are listed. All the goods except for silk were brought from west to east. The documents also witness Sogdians’ monopoly of the Silk Road trade as well as their collaboration in their activities conducted in towns located along the trade route. When Tang China lost its control of Central Asia after the An Lushan Rebellion (755–763 ce), relative importance of the overland trade shifted to that of the maritime route, and Sogdians’ role as traders between China and West was taken over by Persian and Islamic traders.
The Classical Silk Road: Trade and Connectivity across Central Asia, 100 BCE–1200 CE
Authors: Hansen Valerie
Published: May 2021

The Silk Road refers to all the overland routes connecting the major oasis kingdoms of Central Asia including Dunhuang, Turfan, Khotan, and Samarkand to their neighbors: the Chinese landmass, the Mongolian grasslands, the Iranian plateau, and the Indian subcontinent. The best-known routes ran east-west, but the north-south routes to the nomadic states of the Asian grasslands were also important.

In the popular view of the Silk Road, extensive camel caravans carried goods over long distances, but this was rarely the case. Usually peddlers carried mostly local goods short distances. Government shipments to provision armies profoundly affected the region’s economy, because they involved much larger quantities than in the peddler trade.

Rulers regularly exchanged envoys who carried gifts, exchanges that continued even when private trade fell off. Whatever the reason for an individual’s trip, almost everyone—whether envoy, missionary, artist, craftsman, or refugee—bought and sold goods to pay for travel along the Silk Road.

Silk was not the primary commodity traded on these routes. Goods traveling east included ammonium chloride, paper, silver, gold, glassware, and aromatics such as spices, incense, and fragrant woods. Goods traveling west out of China included bronze mirrors, other metal goods, and paper, in addition to silk. Between 300 and 1000 ce, the most important function of silk was as a currency, not as a trade good, although it remained an important export throughout the period.

A vibrant series of cultural exchanges occurred alongside these commercial exchanges. Technologies, medicine, plants, music, and fashion all moved in both directions across Central Asia. Multiple religions also entered China during this time.

The term Silk Road may not be the most accurate term for these commercial and cultural exchanges, but, despite its flaws, the term has secured a firm place in both scholarly works and the popular mind.
Do Households Respond to the Marginal or Average Price of Piped Water Services?
Authors: Cook Joseph , Brent Daniel
Published: May 2021

Water utilities commonly use complex, nonlinear tariff structures to balance multiple tariff objectives. When these tariffs change, how will customers respond? Do customers respond to the marginal volumetric prices embedded in each block, or do they respond to an average price? Because empirical demand estimation relies heavily on the answer to this question, it has been discussed in the water, electricity, and tax literatures for over 50 years. To optimize water consumption in an economically rational way, consumers must have knowledge of the tariff structure and their consumption. The former is challenging because of nonlinear tariffs and inadequate tariff information provided on bills; the latter is challenging because consumption is observed only once and with a lag (at the end of the period of consumption). A large number of empirical studies show that, when asked, consumers have poor knowledge about tariff structures, marginal prices, and (often) their water consumption.

Several studies since 2010 have used methods with cleaner causal identification, namely regression discontinuity approaches that exploit natural experiments across changes in kinks in the tariff structure, changes in utility service area borders, changes in billing periods, or a combination. Three studies found clear evidence that consumers respond to average volumetric price. Two studies found evidence that consumers react to marginal prices, although in both studies the change in price may have been especially salient. One study did not explicitly rule out an average price response. Only one study examined responsiveness to average total price, which includes the fixed, nonvolumetric component of the bill.

There are five messages for water professionals. First, inattention to complex tariff schedules and marginal prices should not be confused with inattention to all prices: customers do react to changes in prices, and prices should remain an important tool for managing scarcity and increasing economic efficiency. Second, there is substantial evidence that most customers do not understand complex tariffs and likely do not respond to changes in marginal price. Third, most studies have failed to clearly distinguish between average total price and average volumetric price, highlighting the importance of fixed charges in consumer perception. Fourth, evidence as of late 2020 pointed toward consumers’ responding to average volumetric price, but it may be that this simply better approximates average total price than marginal or expected marginal prices; no studies have explicitly tested this. Finally, although information treatments can likely increase customers’ understanding of complex tariffs (and hence marginal price), it is likely a better use of resources to simplify tariffs and pair increased volumetric charges with enhanced customer assistance programs to help poor customers, rather than relying on increasing block tariffs.
Theory of Change in Sports-Based Urban Youth Programs: Lessons from Creating Chances
Authors: Baffsky Rachel , Kemp Lynn , Bunde-Birouste Anne
Published: May 2021

Sports-based positive youth development (SB-PYD) programs are health promotion programs that intentionally use sports to build life skills and leadership capacity among young people at risk of social exclusion. The defining characteristics of SB-PYD programs are that they are strengths-based, holistic, and use sports as a vehicle to maximize young people’s health, social, and educational outcomes. SB-PYD programs aim to enhance modifiable social determinants of health (such as social inclusion) by explicitly addressing three Ottawa charter action areas; strengthening community action, developing personal skills, and creating supportive environments. These programs have been increasingly implemented since the early 2000s to address the United Nations’ sustainable development goals.

Despite their growth, research indicates that SB-PYD programs are often designed, implemented, and evaluated without evidence-based theories of change. An evidence-based theory of change is a visual depiction of a program’s assumptions, activities, contextual factors, and outcomes supported by scientific findings. A lack of evidence-based theory of change becomes problematic at the implementation phase when practitioners are trying to determine if their programs should be adapted or fixed. Without an evidence-based theory of change, practitioners are making changes based on their intuition, which limits program outcomes.

However, the process of developing a theory of change is time-consuming and resource intensive. Multiple calls to action have been made for SB-PYD practitioners who have successfully developed evidence-based theories of change to share their process with others in the field. This will provide a blueprint for other SB-PYD practitioners to develop and articulate their own theories of change to optimize program development and adaptation.

Traditional translational research models assume the development of an evidence-based theory of change is the first step in a linear process of developing a sustainable health promotion program. However, in the 2010s, researchers started to observe that the development and adaptation of health promotion programs was rarely a linear process in reality, and that case studies are needed to provide empirical support for this claim. It is valuable for SB-PYD practitioners to consider the benefits of using translational research to develop and revise evidence-based theories of change for programs at any stage of implementation to maximize their public health impact.
The Atmosphere of Titan
Authors: Coustenis Athena
Published: May 2021

Titan, Saturn’s largest satellite, is one of the most intriguing moons in our Solar System, in particular because of its dense and extended nitrogen-based and organic-laden atmosphere. Other unique features include a methanological cycle similar to the Earth’s hydrological one, surface features similar to terrestrial ones, and a probable under-surface liquid water ocean. Besides the dinitrogen main component, the gaseous content includes methane and hydrogen, which, through photochemistry and photolysis, produce a host of trace gases such as hydrocarbons and nitriles. This very advanced organic chemistry creates layers of orange-brown haze surrounding the satellite. The chemical compounds diffuse downward in the form of aerosols and condensates and are finally deposited on the surface. There is very little oxygen in the atmosphere, mainly in the form of H2O, CO, and CO2. The atmospheric chemical and thermal structure varies significantly with seasons, much like on Earth, albeit on much longer time scales. Extensive analysis of Titan data from ground, Earth-orbiting observatories, and space missions, like those returned by the 13-year operating Cassini-Huygens spacecraft, reveals a complex system with strong interactions among the atmosphere, the surface, and the interior. The processes operating in the atmosphere are informative of what occurs on Earth and give hints as to the origin and evolution of our outer Solar System.
Radicalization and Deradicalization

What is radicalization, and what drives individuals to become radicalized? Many individuals who hold radical beliefs will never become violent, yet others are compelled to enforce their ideology through violence. Drawing from existing literature, radicalization is defined as a transformation rooted in grievances, networks, enabling environments, and ideology that brings an individual to hold radical beliefs and support the use of violence. Conversely, deradicalization is defined as both a cognitive departure from radical ideology and a behavioral shift away from radical activities and group membership. Competing theories of radicalization and deradicalization have created a debate about whether or not these phenomena must be experienced in a linear fashion, and several scholars posit that strains caused by society can lead to both cognitive and behavioral forms of radicalization. The evidence supporting these theories is demonstrated in the counter-radicalization policies of several Western countries, which use localized policing and community members to address the social and political issues that breed radicalization.

Moreover, radicalization and deradicalization are not “one size fits all” phenomena; instead, they are experiences that can differ between ideologies as well as within ideologies. For example, sociopolitical factors specific to one’s nationality can impact the radicalization and deradicalization of individuals and organizations belonging to the same ideology. Despite all this, there are still significant gaps in the study of radicalization and deradicalization that need to be addressed. In academia, two debates must be settled: how should radicalization be defined, and should radicalization be understood as occurring in a linear or nonlinear fashion? In the policy realm, professionals must understand and address the grievances that increase the risk for radicalization to occur through social programs and education initiatives. Finally, policymakers and academics must communicate with each other regarding the research needs for enacting sound policies that will reduce the occurrence of radicalization.
South African Foreign Policy

In its foreign policy posture and ambitions, post-apartheid South Africa is like no other country on the continent, having earned the reputation of punching above its weight. Upon rejoining the international community in the mid-1990s based on a new democratic and African identity, it laid out and invested considerable material and intellectual resources in pursuing a vision of the world that was consistent with the ideals and aspirations of the indigenous anti-apartheid movement. This translated into a commitment to foreground the ideals of human rights, democratic governance, and socioeconomic justice in its foreign relations, which had been reoriented away from their Western focus during the apartheid period, to give expression to post-apartheid South Africa’s new role conception as a champion of the marginalized interests for Africa and rest of the Global South. Since the start of the 21st century, this new foreign policy orientation and its underlying principles have passed through various gradations, reflecting not only the personal idiosyncrasies of successive presidents but also changes in the domestic environment as well as lessons learned by the new crop of leaders in Pretoria, as they sought to navigate a complex and fluid continental and global environment. From a rather naive attempt to domesticate international politics by projecting its constitutional values onto the world stage during the presidency of Nelson Mandela, South Africa would be socialized into, and embrace gradually, the logic of realpolitik, even as it continued to espouse an ethical foreign policy, much to the chagrin of the detractors of the government of the African National Congress within and outside the country. With the fading away of the global liberal democratic consensus into which post-apartheid South Africa was born, coupled with a crumbling of the material and moral base that had at some point inspired a sense of South African exceptionalism, Pretoria’s irreversible march into an unashamedly pragmatic and interest-driven foreign policy posture is near complete.
