Effects of salinity variations on pore water flow in salt marshes
Authors: Shen Chengji , Jin Guangqiu , Xin Pei , Kong Jun , Li Ling 
Published: May 2015

AbstractSpatial and temporal salinity variations in surface water and pore water commonly exist in salt marshes under the combined influence of tidal inundation, precipitation, evapotranspiration, and inland freshwater input. Laboratory experiments and numerical simulations were conducted to investigate how density gradients associated with salinity variations affect pore water flow in the salt marsh system. The results showed that upward salinity (density) gradients could lead to flow instability and the formation of salt fingers. These fingers, varying in size with the distance from the creek, modified significantly the pore water flow field, especially in the marsh interior. While the flow instability enhanced local salt transport and mixing considerably, the net effect was small, causing only a slight increase in the overall mass exchange across the marsh surface. In contrast, downward salinity gradients exerted less influence on the pore water flow in the marsh soil and slightly weakened the surface water and groundwater exchange across the marsh surface. Numerical simulations revealed similar density effects on pore water flow at the field scale under realistic conditions. These findings have important implications for studies of marsh soil conditions concerning plant growth as well as nutrient exchange between the marsh and coastal marine system.
A Bio‐Social‐Cultural Approach to Early Cognitive Development: Entering the Community of Minds
Authors: Nelson Katherine 
Published: May 2015

AbstractImportant cognitive changes take place during the preschool years in addition to the acquisition of a first language. A bio‐social‐cultural (BSC) theory is needed to explicate the relation between language and cognition during this period of development. The foundations of the BSC approach in evolutionary and developmental systems theory are noted and applied to the emergence of autobiographical memory and the understanding of one's own and other minds within the general conception of “entering the community of minds” a conceptual framework for the social‐cultural components of this approach. The need for further theoretical and empirical research including neurological change during this period is indicated.
Agency as an Explanatory Key: Theoretical Issues
Authors: Biernacki Richard , Skotnicki Tad 
Published: May 2015

AbstractIn philosophy agency designates the inalienable ability of individuals to make choices about their conduct that are not determined by the environment. In empirical social science, however, agency designates not autonomous free will but the launching of patterned action that surpasses constraints in the setting and that directs the course of institutional change. Many social scientists have limited the explanatory task they take on to show that agency is an indispensable part of ongoing social life. They have also reasoned that portrayals of institutional structures alone or even of the cultural resources that accompany them, such as shared scripts for social interaction, are inadequate for explaining important changes. It is typical therefore to feature agency as a logically necessary contributor. Study of agency can be improved by specifying affirmatively when and how action is in decisive ways organized independently of the constraints in the setting and this sense transcends them. This sharper requirement for positive demonstration of how agency brought about change is satisfied by reconstructing the actors' independent invention of a new master problem that guides their conduct. This promising approach to explaining transformative action has disseminated from study of artistic and scientific innovation to that of institutional change.
Against Game Theory
Authors: Lucas Gale M. , McCubbins Mathew D. , Turner Mark 
Published: May 2015

AbstractPeople make choices. Often, the outcome depends on choices other people make. What mental steps do people go through when making such choices? Game theory, the most influential model of choice in economics and the social sciences, offers an answer, one based on games of strategy such as chess and checkers: the chooser considers the choices that others will make and makes a choice that will lead to a better outcome for the chooser, given all those choices by other people. It is universally established in the social sciences that classical game theory (even when heavily modified) is bad at predicting behavior. But instead of abandoning classical game theory, those in the social sciences have mounted a rescue operation under the name of “behavioral game theory.” Its main tool is to propose systematic deviations from the predictions of game theory, deviations that arise from character type, for example. Other deviations purportedly come from cognitive overload or limitations. The fundamental idea of behavioral game theory is that, if we know the deviations, then we can correct our predictions accordingly, and so get it right. There are two problems with this rescue operation, each of them is fatal. (i) For a chooser, contemplating the range of possible deviations, as there are many dozens, actually makes it exponentially harder to figure out a path to an outcome. This makes the theoretical models useless for modeling human thought or human behavior in general. (ii) Modeling deviations are helpful only if the deviations areconsistent, so that scientists (and indeed decision makers) can make predictions about future choices on the basis of past choices. But the deviations are not consistent. In general, deviations from classical models are not consistent for any individual from one task to the next or between individuals for the same task. In addition, people's beliefs are in general not consistent with their choices. Accordingly, all hope is hollow that we can construct a general behavioral game theory. What can replace it? We survey some of the emerging candidates.
AIDS
and Social Networks
Authors: Weinreb Alexander , Adams Jimi , Trinitapoli Jenny 
Published: May 2015

Abstract
During the past 30 years, research on the global AIDS pandemic and on social networks has coevolved. Insights from social networks literature have advanced our understandings of AIDS; simultaneously, key empirical insights from the AIDS literature have furthered the development of social network research—especially methodologically. We elaborate on this reciprocal relationship, identifying some of the key developments and future directions for research on AIDS and on social networks generally. From existing literatures, we discuss how (i) social networks analysis was central to early attempts to understand the spread of HIV through sexual and needle‐sharing relationships; (ii) subsequent prevention efforts leveraged similar insights to different ends; (iii) social networks have been crucial in understanding patterns of care for people living with HIV/AIDS; and (iv) the structural composition of networks across international, organizational, and individual levels highlights the epidemic's global implications in ways that extend far beyond epidemiology. We contend that future research must integrate recent developments from both fields in order advance understandings. Among these, we identify as most promising: (i) a move from static modeling approaches toward research emphasizing the dynamic properties of networks; (ii) a shifting focus from single networks in isolation (e.g., sexual transmission networks) to the analysis of multiplex networks (i.e., those involving multiple relationship types represented simultaneously); and (iii) an acknowledgment—conceptual and methodological—of the “vertical” embeddedness of networks. Continued advances in this area will require the gathering of high quality social network data specifically designed to address such questions.
Ambivalence and Inbetweeness
Authors: Giesen Bernhard 
Published: May 2015

AbstractIn the following remarks, we present new developments in social theory and cultural analysis that converge in a particular focus on a third perspective beyond the distinction between inside and outside. This focus on “thirdness” transcends the classical structuralist paradigm of binary classification. It is especially sensitive for the analysis of sudden surprises, paradoxical twists, and disturbing events in history and social life and, thus, contrasts to the assumption of progress and orderly linear development. We outline this new paradigm with respect to three different domains: garbage, monsters, and victims.
An Evolutionary Perspective on Developmental Plasticity
Authors: Hartman Sarah , Belsky Jay 
Published: May 2015

AbstractIn this essay, we advance the argument that variations in developmental plasticity should be treated as an individual‐difference construct in research on environmental influences on human development. As guided by the diathesis‐stress framework, past research has focused mainly on the development of dysfunction and negative outcomes in “vulnerable” individuals and the absence of such effects in “resilient” ones in response to adverse developmental experiences and environmental exposures. An evolutionary perspective challenges this traditional and prevailing framework for understanding person‐X‐environment interaction, leading to the view that there are individual differences in developmental plasticity, with those individuals most susceptible to the negative effects of adverse experiences also most likely to benefit from positive ones. Evidence consistent with this view is summarized and directions for future research are outlined.
An Imaging Gene by Environment Interaction (IG×E) Approach to Understanding Youth Antisocial Behavior
Authors: Waller Rebecca , Dotterer Hailey L. , Hyde Luke W. 
Published: May 2015

AbstractAn examination of the complex interplay of genes, environmental experience, and the brain is critical to understanding psychopathology, violence, and aggression. This essay reviews the gene–environment (G×E) interaction and imaging genetics literature relating to the development of youth antisocial behavior (AB). A model is proposed that bridges these approaches within an imaging gene×environment (IG×E) interaction framework. The potential application of an IG×E framework to youth AB is outlined and ongoing research challenges are discussed.
Applications of Selective Exposure and Attention to Information for Understanding Health and Health Disparities
Authors: Earl Allison , Nisson Christina 
Published: May 2015

AbstractIn this essay, we discuss how social psychological work on selective exposure and attention can be used to understand information selection decisions in a health context. In particular, we begin with an overview of the selective exposure and attention literatures, including a summary of literature suggesting that people are more likely to seek out (selective exposure) and pay attention to (selective attention) information they agree versus disagree with. We then discuss various motives that may influence information selection and attention. Finally, we conclude with a summary of how the work on selective exposure and attention can be brought to bear on health message design and reduction of health disparities.
Architecture of Markets
Authors: Fligstein Neil , Calder Ryan 
Published: May 2015

AbstractMarkets are socially constructed arenas where repeated exchanges occur between buyers and sellers under a set of formal and informal rules governing relations among competitors, suppliers, and customers. These arenas operate according to local understandings and rules that guide interaction, facilitate trade, define what products are produced, indeed constitute the products themselves, and provide stability for buyers, sellers, and producers. Marketplaces are also dependent on governments, laws, and cultural understandings supporting market activity. Our essay provides a brief exposition of this perspective. Then, it considers cutting‐edge work on three topics: (i) the formation of markets and prices, (ii) the organization of capitalism in different societies, and (iii) financialization and globalization. We suggest that in the future, path breaking research will: (i) explore the sociology of consumption, (ii) combine insights from the sociology of markets and from studies of the role of economic thought in constructing markets, and (iii) investigate national and transnational regulations.
Assimilation and Its Discontents
Authors: Zhou Min 
Published: May 2015

AbstractThis essay offers a review of the scholarly literature on immigrant assimilation, looking at how classical assimilation theories explain the processes and outcomes of assimilation among contemporary immigrants and their offspring and how alternative theories are developed to address assimilation's discontents. The essay first revisits the commonly held assumptions underlying classical theories of assimilation and investigates why even normative pathways can lead to divergent assimilation outcomes. It then discusses new theoretical development in this area, highlighting the central ideas and conceptualization of the segmented assimilation theory and the neoclassical assimilation theory. The author emphasizes how multilevel determinantsinteractto produce unconventional pathways that have profound implication for success or failure of assimilation. She also suggests that researchers problematize the notions of “success” or “failure,” paying special attention to how immigrants and their offspring, rather than social scientists themselves, imagine and frame these notions because subjective conceptualization can influence strategies that result in vastly different pathways and outcomes. The essay concludes with a discussion on issues for future research.
Attention and Perception
Authors: Rensink Ronald A. 
Published: May 2015

AbstractThis essay discusses several key issues concerning the study of attention and its relation to visual perception, with an emphasis on behavioral and experiential aspects. It begins with an overview of several classical works carried out in the latter half of the twentieth century, such as the development of early filter and spotlight models of attention. This is followed by a survey of subsequent research that extended or modified these results in significant ways. It includes work on various forms of induced blindness and on the capabilities of nonattentional processes. It also covers proposals about how a “just‐in‐time” allocation of attention can create the impression that we see our surroundings in coherent detail everywhere, as well as how the failure of such allocation can result in various perceptual deficits. The final section examines issues that have not received much consideration to date, but that may be important for new lines of research in the near future. These include the prospects for a better characterization of attention, the possibility of more systematic computational explanations, factors that may significantly modulate attentional operation, and the possibility of several kinds of visual attention and visual experience.
Becoming Adult: Meanings of Markers to Adulthood
Authors: Settersten Richard A. , Ottusch Timothy M. , Schneider Barbara 
Published: May 2015

AbstractThis essay examines a range of meanings and markers of adulthood, from biological to social, psychological, and legal. It describes a shift from more universal and traditional definitions of adulthood, which were also heavily gendered, to an increasingly diverse and personalized set of definitions. This shift reflects the prolonged, complex, and highly unequal spectrum of pathways that young people take into adulthood today. And yet, public perceptions of what adulthood is supposed to look like, and even the views of young people themselves, are often anchored in an earlier historical era. The clash between outdated ideas and the new realities of adulthood create a major set of contradictions for young people. Two contexts are shown to be crucial in determining individuals' actual and perceived progress toward adulthood: families and institutions of higher education. But in these contexts, too, young people receive contradictory signals about their status. The essay concludes with thoughts about the changing meanings of what it means to be “young” and “adult” today.
Behavioral Economics
Authors: Hochman Guy , Ariely Dan 
Published: May 2015

Abstract
Standard economic models portray decision makers as perfectly rational agents who act selfishly to maximize their total earnings. In contrast, ample evidence in behavioral research suggests that people systematically deviate from the extreme rational assumption of such economic models. Behavioral economics is aimed at identifying the forces which shape the economic decisions that people make, in order to provide important insights of the human nature. This type of research often deals with questions such as how the presentation of information effect decision making, how different types and valances effect behavior, and what are the social, emotional, and situational factors that underlie economic decision making. This article describes foundational research in behavioral decision making and economics that lead to the emergence of behavioral economics; outline cutting‐edge research on applied behavioral economics, debiasing techniques, and neuroeconomics; and discusses key issues for future research, such as the use of field experiments and tailor‐made methodologies, and focusing on a more comprehensive approach. Our hope is that as behavioral economics advances it will examine not only the nature of the decisions people make but also their underlying cognitive processes.
How Brief Social‐Psychological Interventions Can Cause Enduring Effects
Authors: Kenthirarajah Dushiyanthini (Toni) , Walton Gregory M. 
Published: May 2015

AbstractIn recent years, several studies have shown that brief, theory‐based social‐psychological interventions can cause large, enduring effects on important outcomes, such as school achievement and marital relationships. How are such effects possible? We propose afield‐theory model: this model distinguishes “nudge” interventions—interventions designed to change a “snapshot” in time such as a particular decision or behavior—from interventions designed to change a “movie”—core beliefs or other aspects of the self and thus people's behavior as it unfolds over time in diverse settings.Movie interventionstarget underlying social‐psychological processes—such as students' confidence that they belong in school or individuals' felt security in close relationships. These psychological processes can interact with naturalistic variables—such as how people interact with one another and the relationships they build—to propel intervention effects forward in time. In this model, real‐world factors can serve as proximal outcomes that catalyze long‐term effects. An important implication is that such interventions can sometimes amplify their effects over time, if the targeted recursive process “snowballs.” A second implication is that the long‐term effects of movie interventions are dependent on the context—specifically, on whether the context affords naturalistic variables that can catalyze changes in the self forward in time. To illustrate thisfield‐theory model, we compare it to Mortensen and Cialdini's (2010)full‐cycle model. Although both models share important features, including an emphasis on laboratory research, the latter treats forces in the world as “noise” and predicts that the effects of psychological interventions will dissipate, not strengthen with time. In addition to their applied potential, movie interventions raise profound new theoretical questions, such as how psychological processes unfold over time and do so in interaction with social contexts. Exploring these questions represents an exciting direction for future research.
Built Environments and the Anthropology of Space
Authors: McDonogh Gary W. 
Published: May 2015

AbstractAnalysis of human interaction with and interpretations of the surrounding physical world has been of fundamental interest for anthropology since its emergence as a discipline in the nineteenth century. The comparative description of homes, monumental spaces, and worked landscapes has provided foundations for social and cultural analysis and facilitated early exchanges with archaeology, architecture history, and linguistics. Over time, changes in the lives of those with whom anthropologists work and the concomitant expansion of urban anthropologies have promoted new questions as well as expanding interactions with geography, social theory, urban studies and gender, class, ethnic, and cultural studies while engaging anthropologists in wider public participation. Future anthropologies of space and place should continue to build on these methodological, data and theoretical heritages, including fieldwork and global comparisons, while expanding interdisciplinarity and engaging civic perspectives. Building on these foundations, anthropologists will need to address environmental concerns in their broadest scope. They will also grapple with the methodological and theoretical challenges of changing mobilities and similarly analyze rapidly evolving (electronic) mediations and virtual spaces and communities while sharing this knowledge in wider academic and public discussions.
Bullying and Cyberbullying
Authors: Bauman Sheri , Taylor Aryn 
Published: May 2015

Abstract
The purpose of this essay is to explore diverse forms of bullying according to multiple theoretical frameworks of aggression, victimization, and human development. We comment on existing anti‐bullying legislation and bullying prevention programs. Bullying manifests in a variety of settings, and with the popularity and accessibility of the Internet, a new form of bullying has become prevalent: cyberbullying or cyber aggression. Different forms of cyber aggression are discussed, as well as psychosocial implications for both aggressors and victims. Current trends in bullying and cyber aggression such as Internet trolling and innovative prevention strategies are detailed, as well as potential areas of future research in the social and behavioral sciences.
Causes of Fiscal Crises in State and Local Governments
Authors: Kogan Vladimir 
Published: May 2015

AbstractFinancial insolvency is a rare occurrence in American state and local governments. However, when it does happen, as in the case of Detroit's historical bankruptcy filing in 2013, the consequences for vital city services, public employees, and taxpayers can be devastating. This essay reviews existing and emerging research on the causes of government fiscal crises, paying particular attention to how social, economic, and legal constraints interact with the electoral incentives faced by public officials to create financial distress. It concludes by identifying a number of open questions that should guide future research, to help identify potential institutional and political reforms that can help avert future problems before they occur.
