Field-anneal-induced magnetic anisotropy in highly textured Fe-Al magnetostrictive strips
Authors: Park Jung Jin , Na Suok-Min , Flatau Alison B.
Published: March 2017

Highly textured (011)[100] Goss-oriented rolled sheet Fe-Al alloy is a promising magnetostrictive material for use in bending mode sensors and vibrational energy harvesters. In this paper, we performed magnetic field annealing (FA) to induce magnetic anisotropy in strips of highly textured Fe-Al. Prior work suggests FA as a viable alternative to stress annealing (SA), which leads to buckling of Fe-Al rolled sheet samples. The Fe-Al strips studied here exhibited tetragonal magnetostriction values ((3/2)λsat = λ∥ − λ⟂) of ∼136 ppm along their length, which corresponds to ∼78% of the single crystal value along a <100> orientation. The effectiveness of FA on magnetic moment rotation was inferred by comparing post-FA magnetostriction measurements with the maximum possible yield, where λ∥= 0 and λ⟂= (3/2)λsat. Strain gauge data from the middle of the strip indicates that FA achieved ∼27% of the desired built-in uniaxial anisotropy along the parallel direction of the strip length, decreasing λ∥ by 25 ppm of the 95 ppm. Hall effect sensor data was used to assess the potential effect of FA on sensing and energy harvesting performance. FA improved the bending-stress-induced changes in magnetization near the clamped end of the strips by ∼45%. These results suggest that the FA was more effective in the region near the end of the strip than toward the middle of the strip, which we explain may be a result of the use of high temperature permanent magnets at the ends of the strips for the FA protocol.
Reconstruction of Kelvin probe force microscopy image with experimentally calibrated point spread function
Authors: Lan Fei , Jiang Minlin , Tao Quan , Wei Fanan , Li Guangyong
Published: March 2017

A Kelvin probe force microscopy (KPFM) image is sometimes difficult to interpret because it is a blurred representation of the true surface potential (SP) distribution of the materials under test. The reason for the blurring is that KPFM relies on the detection of electrostatic force, which is a long-range force compared to other surface forces. Usually, KPFM imaging model is described as the convolution of the true SP distribution of the sample with an intrinsic point spread function (PSF) of the measurement system. To restore the true SP signals from the blurred ones, the intrinsic PSF of the system is needed. In this work, we present a way to experimentally calibrate the PSF of the KPFM system. Taking the actual probe shape and experimental parameters into consideration, this calibration method leads to a more accurate PSF than the ones obtained from simulations. Moreover, a nonlinear reconstruction algorithm based on total variation (TV) regularization is applied to KPFM measurement to reverse the blurring caused by PSF during KPFM imaging process; as a result, noises are reduced and the fidelity of SP signals is improved.
Density functional theory and simulations of colloidal triangular prisms
Authors: Marechal Matthieu , Dussi Simone , Dijkstra Marjolein
Published: March 2017

Nanopolyhedra form a versatile toolbox to investigate the effect of particle shape on self-assembly. Here we consider rod-like triangular prisms to gauge the effect of the cross section of the rods on liquid crystal phase behavior. We also take this opportunity to implement and test a previously proposed version of fundamental measure density functional theory (0D-FMT). Additionally, we perform Monte Carlo computer simulations and we employ a simpler Onsager theory with a Parsons-Lee correction. Surprisingly and disappointingly, 0D-FMT does not perform better than the Tarazona and Rosenfeld’s version of fundamental measure theory (TR-FMT). Both versions of FMT perform somewhat better than the Parsons-Lee theory. In addition, we find that the stability regime of the smectic phase is larger for triangular prisms than for spherocylinders and square prisms.

Published: March 2017

We describe an instrument that exploits the ongoing revolution in synchrotron sources, optics, and detectors to enable in situ studies of metal-organic vapor phase epitaxy (MOVPE) growth of III-nitride materials using coherent x-ray methods. The system includes high-resolution positioning of the sample and detector including full rotations, an x-ray transparent chamber wall for incident and diffracted beam access over a wide angular range, and minimal thermal sample motion, giving the sub-micron positional stability and reproducibility needed for coherent x-ray studies. The instrument enables surface x-ray photon correlation spectroscopy, microbeam diffraction, and coherent diffraction imaging of atomic-scale surface and film structure and dynamics during growth, to provide fundamental understanding of MOVPE processes.
Nanosecond magnetization dynamics during spin Hall switching of in-plane magnetic tunnel junctions

Published: March 2017

We present a study of the magnetic dynamics associated with nanosecond scale magnetic switching driven by the spin Hall effect in 3-terminal nanoscale magnetic tunnel junctions (MTJs) with in-plane magnetization. Utilizing fast pulse measurements in a variety of material stacks and detailed micromagnetic simulations, we demonstrate that this unexpectedly fast and reliable magnetic reversal is facilitated by the self-generated Oersted field, and that the short-pulse energy efficiency can be substantially enhanced by spatial non-uniformity in the initial magnetization of the magnetic free layer. The sign of the Oersted field is essential for this enhancement—in simulations in which we artificially impose a field-like torque with a sign opposite to the effect of the Oersted field, the result is a much slower and stochastic switching process that is reminiscent of the so-called incubation delay in conventional 2-terminal spin-torque-switched MTJs.

Published: March 2017

For multifarious electronic and optoelectronic applications, it is indispensable exploration of stable and simple method to modulate electrical behavior of transition metal dichalcogenides (TMDs). In this study, an effective method to adjust the electrical properties of ambipolar TMDs is developed by introducing the dipole electric field from poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) ferroelectric polymer. The transition from ambipolar to p-type conductive characteristics is realized, and the transistor performances are also significantly enhanced. Hole density of MoTe2- and WSe2-based back-gate field effect transistors increases by 4.4 and 2.5 times. Moreover, the corresponding hole mobilities are strikingly improved from 0.27 to 10.7 cm2 V−1 s−1 and from 1.6 to 59.8 cm2 V−1 s−1, respectively. After optimizing, p-channel MoTe2 phototransistors present ultrahigh responsivity of 3521 A/W, which is superior to most layered phototransistors. The remarkable control of conductive type, carrier concentration, and field-effect mobility of ambipolar TMDs via P(VDF-TrFE) treatment paves a way for realization of high-performance and versatile electronic and optoelectronic devices.
Effect of dust on drift magnetosonic wave in anisotropic low beta plasma
Authors: Uzma Ch. , Naim H. , Murtaza G.
Published: March 2017

Dust particles that are ubiquitously present in space interact with the space plasma and can modify the existing modes and affect the growth rate of instability. In this work, the effects of homogeneous dust on the obliquely propagating anisotropic, low beta drift magnetosonic wave, and its related kinetic instability are analyzed using the gyrokinetic model. A comparison is made of different effects due to the dust density, the ions and electrons density inhomogeneity, and the temperature anisotropy. It is observed that both the temperature anisotropy and the presence of dust species augment each other in suppressing the growth of the drift instability. Our results may, therefore, be useful in studying the propagation characteristics of drift magnetosonic wave in space near the Sun where the environment is anisotropic, and the dust species also exist.
Bulk modulus of two-dimensional liquid dusty plasmas and its application
Authors: Li Wei , Lin Wei , Feng Yan
Published: March 2017

From the recently obtained equation of state [Feng et al., J. Phys. D: Appl. Phys. 49, 235203 (2016) and Feng et al., Phys. Plasmas 23, 093705 (2016); Erratum 23, 119904 (2016)], the bulk modulus of elasticity K of 2D liquid dusty plasmas is analytically derived as the expression of the temperature and the screening parameter. Exact values of the obtained bulk modulus of elasticity K are reported and also plotted in the 2D plane of the temperature and the screening parameter. As the temperature and the screening parameter change, the variation trend of K is reported and the corresponding interpretation is suggested. It has been demonstrated that the obtained bulk modulus of elasticity K can be used to predict the longitudinal sound speed, which agrees well with previous studies.
Piezoelectric energy harvester for low engine vibrations
Authors: Khalatkar A. M. , Gupta V. K.
Published: March 2017

Piezoelectric materials are well known for their use as sensors and actuators in flexible structures. Researchers have also focused on harvesting energy from the waste vibrations generated by different sources using piezoelectric materials. In its running condition, an engine generates vibrations. These vibrations can be converted into electric energy by using a suitable energy harvester. The minute energy generated from these waste vibrations can be used as an additional source to batteries or a resource to run sensors and actuators in automotive vehicles. This paper focuses on harvesting energy from engine vibrations using a piezoelectric cantilever beam. The power from these vibrations has been enhanced even at low vibrations. A mathematical equation for the estimation of voltage and power using a piezoelectric cantilever beam has been derived. The effect of excitation frequency, amplitude, and material properties on power output has been considered. Based on the simulation results, a piezoelectric cantilever beam is designed and fabricated, and experiments are conducted. Analytical results are validated with the experimental results, and a close match has been observed between the experimental and analytical results.

Published: March 2017

We have fabricated ferrite cantilevers in which their vibrational properties can be controlled by external magnetic fields. Submicron-scale cantilever structures were made from Y3Fe5O12 films by physical etching combined with the use of a focused ion beam milling technique. We found that the cantilevers exhibit two resonance modes which correspond to horizontal and vertical vibrations. Under external magnetic fields, the resonance frequency of the horizontal mode increases, while that of the vertical mode decreases, quantitatively consistent with our numerical simulation for magnetic forces. The changes in resonance frequencies with magnetic fields reach a few percent, showing that an efficient magnetic control of resonance frequencies was achieved.
Control of threshold voltage by gate metal electrode in molybdenum disulfide field-effect transistors
Authors: Kawanago Takamasa , Oda Shunri
Published: March 2017

This study reports the control of threshold voltage (Vth) by engineering a gate metal electrode in molybdenum disulfide (MoS2) field-effect transistors (FETs). The fabrication process for gate stacks involves the deposition of aluminum oxides (AlOx) on a high-work-function metal and the subsequent formation of a self-assembled monolayer (SAM) by an immersion method. A positive Vth of 0.15 V was demonstrated using a platinum (Pt) metal as a gate electrode accompanied by a low density of traps at the interface owing to the close-packed SAM. Raman spectroscopy revealed that the transferred MoS2 has a multi-layer structure. The Pt gate electrode exhibits a Vth shift of about 1 V in the positive direction compared with the aluminum (Al) gate electrode. This Vth shift is consistent with the difference in the work function of Pt and Al gate metal electrodes. The low–temperature process employed in this study makes it possible to assemble dissimilar materials including the Pt metal, deposited AlOx, and organic SAM molecules to manipulate the Vth in MoS2 FETs. This work is expected to open up intriguing directions for research on the applications and developments of functional FETs based on two-dimensional materials.
Influence of Movement Dynamics on Walleye Harvest Management in Intermixed Fisheries in a Chain of Lakes
Authors: Herbst Seth J. , Stevens Bryan S. , Hayes Daniel B. , Hanchin Patrick A.
Published: March 2017

Fish populations that exhibit movement patterns present challenges to fishery management. In the Inland Waterway in Michigan's northern Lower Peninsula, monitoring Walleye Sander vitreus population dynamics and harvest management is difficult because of seasonal intermixing among interconnected lakes. In addition, the presence of tribal subsistence fishing and recreational angling fisheries that occur during different discrete time periods adds complexity to understanding harvest management performance. We used stochastic simulation to determine the influence of movement and harvest dynamics on the performance of harvest management targets for Walleye in our study system. After accounting for postspawn movement and harvest dynamics, our results indicated that population-specific exploitation rates on average did not exceed the target rates (u = 0.35) that are mandated in the waterway. We did, however, determine that some areas are at risk because they experienced population-specific exploitation rates that surpassed the target. We also determined that the interplay between movement and uncertain population and harvest dynamics will likely determine the ability of management to meet currently accepted harvest targets on average over time, as well as the risk of exceeding harvest targets each year. Our findings are broadly applicable for mobile species inhabiting lake chains and highlight that it is critical for managers to gain an understanding of movement as well as harvest dynamics, because both are imperative for understanding how these dynamics influence harvest management performance. As such, we recommend that managers of Walleye populations in other waterways implement tagging studies and harvest monitoring programs to gain an understanding of movement rates and harvest dynamics. An understanding of movement and harvest dynamics along with the stochastic simulation framework we used provides a better understanding of complex system dynamics and leads to informed harvest management decisions.

Gender vs. Sex
Authors: Guenther Elisabeth Anna , Humbert Anne Laure , Kelan Elisabeth Kristina
Published: March 2017

Gender research goes beyond adding sex as an independent, explanatory category. To conduct gender research in the field of business and management, therefore, it is important to apply a more sophisticated understanding of gender that resonates with contemporary gender theory. This entails taking the social construction of gender and its implications for research into consideration. Seeing gender as a social construct means that the perception of “women” and “men,” of “femininity/ties” and “masculinity/ties,” is the outcome of an embodied social practice.

Gender research is commonly sensitive to notions of how power is reproduced and challenges concepts such as “hegemonic masculinity” and “heteronormativity.” The first highlights power relations between gender groups, as well as the different types of existing masculinities. The latter emphasizes the pressure to rely on a binary concept of “women” and “men” and how this is related to heterosexuality, desire, and the body. Gender research needs to avoid the pitfalls of a narrow, essentialist concept of “women” and “men” that draws on this binary understanding of gender. It is also important to notice that not all women (or men) share the same experiences. The critique of Black feminists and scholars from the global South promoted the idea of intersectionality and postcolonialism within gender research. Intersectionality addresses the entanglement of gender with other social categories, such as age, class, disability, race, or religion, while postcolonial approaches criticize the neglect of theory and methodology originating in the global South and question the prevalence of concepts from the global North.

Various insights from gender theory inform business and management research in various ways. Concepts such as the “gendered organization” or “inequality regime” can be seen as substantial contributions of gender theory to organization theory. Analyzing different forms of masculinities and exploring ways in which gender is undone within organizations (or whether a supposedly gender-neutral organization promotes a masculine norm) can offer thought-provoking insights into organizational processes. Embracing queer theory, intersectionality, and postcolonial approaches in designing research allows for a broader image of the complex social reality. Altogether management studies benefit from sound, theoretically well-grounded gender research.
Faultlines
Authors: Murnighan* Keith , Lau Dora
Published: March 2017

Group faultlines are hypothetical dividing lines that may split a group into subgroups based on one or more attributes. An example of a strong faultline is a group of two young female Asians and two senior male Caucasians. Members’ alignment of age, sex, and ethnicity facilitates the formation of two homogeneous subgroups. On the other hand, when a group consists of a young female Asian, a young male Caucasian, a senior female Caucasian, and a senior male Asian, the group faultline is considered weak because subgroups, regardless of how they are formed, are diverse.

As a relatively new form of group compositional pattern, the group faultline is associated with subgroup formation, and these subgroups, rather than the whole group, can easily become the focus of attention. When members strive to obtain more resources and protect their subgroups, between-subgroup conflict, behavioral disintegration, lack of trust, lack of willingness to share information, and communication challenges are likely. As a result, group performance is often negatively affected, and sometimes groups may even be dissolved. These results were repeatedly found in studies of experimental groups, ad-hoc project groups, organizational teams, top management teams, global virtual teams, family businesses, international joint ventures, and strategic alliances.
Narratives in Health and Risk Messaging
Authors: Volkman Julie E.
Published: March 2017

In health and risk communication, evidence is a message feature that can add credibility, realism, and legitimacy to health and risk messages. Evidence is usually defined into two types: statistical or narrative. Statistical evidence employs quantifications of events, places, phenomena, or other facts, while narrative evidence involves stories, anecdotes, cases, or testimonials. While many health and risk messages employ statistical or factual information, narrative evidence holds appeal for health and risk communication for its utility in helping individuals learn their risks and illnesses through stories and personal experiences. In particular, narratives employed as evidence in a health or risk message especially hold value for their ability to communicate experiences and share knowledge, attitudes, beliefs, and ideas about complex health issues, propose behavior change, and assist individuals coping with disease. As a result, the personal experiences shared, whether they are from first-hand knowledge, or recounting another’s experience, can focus attention, enhance comprehension for risks, and recall of health and risk information. Furthermore, readers engage with the story and develop their own emotional responses which may align with the purpose of the health and risk message. Narratives, or stories, can occur in many ways or through various points of view, but the stories that “ring true” to readers often have a sense of temporality, coherence, and fidelity. As a result, formative research and pre-testing of health and risk messages with narratives becomes important to understand individual perceptions related to the health issue and the characters (or points of view). Constructs of perceived similarity, interest, identification, transportation, and engagement are helpful to assess in order to maximize the usefulness and persuasiveness of narratives as evidence within a health and risk message. Additionally, understanding the emotional responses to narratives can also contribute to perceptions of imagery and vividness that can make the narrative appealing to readers. Examining what is a narrative as evidence in health and risk messages, how they are conceptualized and operationalized and used in health and risk messages is needed to understand their effectiveness.
Types of Explanations in Health and Risk Messaging
Authors: Rowan Katherine E.
Published: March 2017

Explanations designed to teach, rather than to support scientific claims in scholarly works, are essential in health and risk communication. Patients explain why they think their symptoms warrant medical attention. Clinicians elicit information from patients and explain diagnoses and treatments. Families and friends explain health and risk concerns to one another. In addition, there are websites, brochures, fact sheets, museum exhibits, health fairs, and news stories explaining health and risk to lay audiences. Unfortunately, research on this important discursive goal is less extensive than is research on persuasion, that is, efforts to gain agreement. One problem is that explanation-as-teaching has not been carefully conceptualized. Some confuse this communication goal and discursive type with its frequent verbal and visual features, such as simple wording or diagrams. Others believe explanation-as-teaching does not exist as a distinctive communication goal, maintaining that all communication is solely persuasive: that is, designed to gain agreement.

Explanation-as-teaching is a distinct and important health communication goal. Patient involvement in decision making requires that both clinicians and patients understand options underlying health-care choices. To explore types of explanation-as-teaching, research provides (a) several ways of categorizing health and risk explanations for lay audiences; (b) evidence that certain textual and graphic features overcome predictable confusions, and (c) illustrations of each explanation type. Additionally, explanation types succeed or fail in part because of the social or emotional conditions in which they are presented so it is important to note research on conditions that support patients, families, and clinicians in benefiting from explanations of health and risk complexities and curricula designed to enhance clinicians’ explanatory skill.
Social and Political Power
Authors: Dowding Keith
Published: March 2017

Power is a complex topic that is viewed in entirely different ways by different writers. Power can be seen as a property of agents, with some agents having more power than others. It can be seen as a property of social systems, where structures hold power. It can be seen in terms of specific actions by people to coerce or dominate or it can be regarded as a subliminal force that leads people to think and behave in one way rather than another. It can be analyzed descriptively to try to explain how it is distributed and critically to argue for changing structures to provide a more egalitarian and fairer distribution.

Power studies flourished in the great community power studies of the 1950s and 1960s. Some of these suggested that democratic nations were controlled by powerful elites who ruled in their own interests; some that power was more widely distributed and elites could not simply rule for themselves; others that in capitalist societies, despite some counterexamples, elites generally ruled in favor of developers and capitalists. Later studies examined how people’s interests are defined in terms of the structural positions in which they find themselves, and how the very ways in which we think and express ourselves affect our individual powers.
Justice Between Generations
Authors: Meijers Tim
Published: March 2017

A wide range of issues in moral, political, and legal philosophy fall under the heading of “intergenerational justice,” such as questions of justice between the young and the old, obligations to more-or-less distant past and future generations, generational sovereignty, and the boundaries of democratic decision-making.

These issues deserve our attention first because they are of great social importance. Solving the challenges raised by aging, stable pension funding, and increasing healthcare costs, for example, requires a view on what justice between age groups demands. Climate change, resource depletion, environmental degradation, population growth, and the like, raise serious concerns about the conditions under which future people will have to live. What kind of world should we bequest to future generations?

Second, this debate has theoretical significance. Questions of intergenerational justice force reconsideration of the fundamental commitments (on scope, pattern, site, and currency) of existing moral and political theories. The age-group debate has led to fundamental questions about the pattern of distributive justice: Should we care about people’s lives considered as whole being equally good? This has implausible implications. Can existing accounts be modified to avoid such problematic consequences?

Justice between nonoverlapping generations raises a different set of questions. One important worry is about the pattern of intergenerational justice—are future generations owed equality, or should intergenerational justice be cast in terms of sufficiency? Another issue is the currency of intergenerational justice: what kind of goods should be transferred? Perhaps the most puzzling worry resulting from this debate translates into a worry about scope: do obligations of justice extend to future people? Most conventional views on the scope of justice—those that focus on shared coercive institutions, a common culture, a cooperative scheme for mutual advantage—cannot easily be extended to include future generations. Even humanity-based views, which seem most hospitable to the inclusion of future generations, are confronted with what Parfit called the nonidentity problem, which results from the fact that future people are mostly possible people: because of the lack of a fixed identity of future people, it is often impossible to harm them in the comparative sense.
Image Theory and the Initiation of Strategic Rivalries
Authors: Pardesi Manjeet S.
Published: March 2017

The assessment of an opponent as a strategic rival is analytically equivalent to evaluating its strategic image. The central decision-makers of states reevaluate the image of other regional states and the great powers of the system in response to strategic shocks, as they have an impact on interstate interaction capacity. Interaction capacity in the international system can be affected by three types of changes—military, political, and economic. A strategic rivalry is a process that initiates when the central decision-makers of at least one state in a dyad ascribe the image of an enemy to the other as a consequence of such shocks. It is important to empirically demonstrate the ascription of these images through a cognitive process because strategic rivalries are a function of decision-maker perceptions by definition. Four types of enemy images are identified here—expansionist states, which are territorially revisionist; hegemonic states, which circumscribe a given state’s foreign policy choices; imperial states, which intervene in a given state’s domestic affairs in addition to being hegemonic; and peer-competitors, who pose latent and/or long-term threats. Once formed, these images are sustained over long periods of time and change only slowly in response to additional strategic shocks. These images also inform the strategy that a given state pursues toward its rival.
The Foreign Policy Implications of Financial Crises
Authors: Kempin Ronja
Published: March 2017

To what extent is the “Euro-crisis” a problem for the EU’s international standing and role? A conceptual framework has been developed based on the five distinct analytical categories: (a) financial resources, (b) changes in the internal political structure and balance of the European Union, (c) shift of priorities, (d) output and effectiveness of EU foreign policy, and (d) soft power and normative dimension. These categories reveal that in Europe, the crisis led to an erosion of the financial and budgetary basis of foreign policy—even if it is more pronounced on the national than the European level. It also accelerated a trend toward the economization of political priorities resulting—among other things—in deepening conflicts among EU member states. These developments have, in turn, eroded both the effectiveness and the soft power of EU foreign policy. The crisis is therefore not only a strain on the European integration process but also a central challenge for the European Union as an international actor.
Use of Force in Foreign Policy
Authors: Quackenbush Stephen L. , Guarrieri Thomas R.
Published: March 2017

Foreign policy analysis has been used effectively to explain the use of force. Several leading approaches and paradigms help explain the use of force as a tool of foreign policy. These approaches are based on the important preliminary step of opening up the black box of state, which highlights the importance of decision making for explaining international politics. The two primary approaches to explaining foreign policy analysis are rational choice theory and psychological theories.

Foreign policy analysis opens the door to a variety of novel and interesting topics. Many topics of domestic politics relate to international conflict, including democratic peace theory, selectorate theory, public opinion, domestic institutions, and leaders. Each of these topics is important for explaining the use of force in foreign policy. Future research on the use of force and international conflict should account for the importance of domestic politics. Studies of leaders, selectorate theory, and the bargaining model of war provide especially promising avenues for future research.
Analogies and Metaphors and Foreign Policy Decision Making
Authors: Flanik William
Published: March 2017

Like all decision making, foreign policy decision making (FPDM) requires transferring meaning from one representation to another. Since the end of the Cold War, students of FPDM have focused increasingly on historical analogies and, to a lesser extent, conceptual metaphors to explain how this transference works. Drawing on converging evidence from the cognitive sciences, as well as careful case studies of foreign policymaking, they’ve shown analogy and metaphor to be much more than “cheap talk.” Instead, metaphor and analogy are intrinsic to policymakers’ cognition.

This article traces the development of this growing literature. So far, FPDM has treated analogy and metaphor separately. It has also paid far more attention to the former than the latter. By contrast, the article argues that analogy and metaphor are not only similar, they are equally essential to cognition. It defines and compares metaphor and analogy, analyzes their socio-cognitive functions in decision making, and charts the evolution of analogy and metaphor research in FPDM. It also suggests the utility of a constructivist-cognitive synthesis for future work in this area.
Psychological Considerations for Paralympic Athletes
Authors: Martin Jeffrey
Published: March 2017

The Paralympics are the pinnacle of sporting competition for athletes with physical and intellectual impairments. Most Paralympians have intellectual or sensory (e.g., visual) or physical (e.g., amputation, spinal cord injury, cerebral palsy) impairments. The Paralympics have become increasingly competitive and larger over the years as they have grown from two countries and 150 athletes in 1952 to 150 countries and about 4,000 athletes in 2012. In the last 10 to 20 years there has been significant interest and growth in the psychology of Paralympic athletes. Researchers are slowly starting to support the value of psychological skills training. Typically, a humanistic personal developmental model that equally values athletes’ well-being and their athletic performance has been advocated. Understanding the various influences on performance and well-being specifically for Paralympians is particularly important given the stress of the Paralympic experience. Research on Paralympians has focused on foundational qualities, which are psychological factors, such as feelings of control, self-awareness, self-esteem, and personality factors. Often these foundation qualities are framed as having an indirect influence on performance through factors like training quality and lifestyle choices (e.g., alcohol consumption).

In additional to foundational qualities, a second area of research targets the psychological methods that are used to develop mental skills and qualities. For instance, competition plans, positive self-talk, and goal setting are all methods used to enhance positive thoughts (e.g., confidence) and reduce negative affect (e.g., anxiety). A third area of focus has to do with facilitative and debilitative factors that influence Paralympic performance. For instance, many Paralympians have to manage chronic pain and avoid overtraining and injury. Many Paralympians have difficulty training, as sport facilities are not always accessible for training. Travel to competition sites, especially involving air travel (with effects such as jet lag), is particularly challenging and can negatively influence performance. Sleeping in the Paralympic village can also be difficult, with many athletes reporting inferior sleep quality. Finally, a small body of research has examined the challenges Paralympians face when retiring from sport.
Street Cultures
Authors: Ilan Johnny
Published: March 2017

Street culture, the states of being, beliefs, and patterns of behavior associated with the most excluded urban populations, can be observed across the world in numerous varieties. Scholars of “slum” life have noted concerns that bear curious similarities over time and space, speaking to issues of exclusion, crime, and criminalization, and to expressive practices that have come to inspire a range of cultural products that are now heavily marketized. Street cultures are at the apex of different debates and studies. Are street cultures, which emphasize entrepreneurial “hustles” and fierce competition, fundamentally different from mainstream cultures of neoliberal capitalism and consumerism? Studying varieties of street culture and the extent to which individuals adhere to them in different ways highlights the complexities of the relationship between the impoverished self and contemporary social structures: new iterations of racism, patriarchy, and inequality. Examining street expressive practices, such as graffiti art, streetwear, and a variety of musical genres, is far from decorative where it reveals new ways in which the disadvantaged are criminalized while the culture industries are reinvigorated. Included populations are both fearful of and fascinated by the urban poor in a manner that simultaneously supports harsh criminal justice measures and cultural exploitation.
Moral Regulation and Media Representations of the Female Body
Authors: Cossins Anne
Published: March 2017

The literature on sexualization is replete with controversial debates surrounding the sexualization of the female body in multiple media formats and how various scholars have sought to understand the social significance of this phenomenon. These debates not only focus on the sheer extent of the sexualization of the female body compared to the male body but also on the types of sexualization in terms of the use of the female body for commercial purposes. Debates range from those with a protectionist theme focused on protecting young women and girls from the damaging effects of sexualization, to those that advocate the imposition of a stricter moral standard for female dress and behavior to feminist debates about the agency of women and girls who freely choose to sexualize their bodies.
Situational Crime Prevention
Authors: Freilich Joshua D. , Newman Graeme R.
Published: March 2017

Situational crime prevention (SCP) is a criminological perspective that calls for expanding the crime-reduction role well beyond the justice system. SCP sees criminal law in a more restrictive sense, as only part of the anticrime effort in governance. It calls for minutely analyzing specific crime types (or problems) to uncover the situational factors that facilitate their commission. Intervention techniques are then devised to manipulate the related situational factors. In theory, this approach reduces crime by making it impossible for it to be committed no matter what the offender’s motivation or intent, deterring the offender from committing the offense, or by reducing cues that increase a person’s motivation to commit a crime during specific types of events. SCP has given rise to a retinue of methods that have been found to reduce crime at local and sometimes national or international levels. SCP’s focus is thus different than that of other criminological theories because it seeks to reduce crime opportunities rather than punish or rehabilitate offenders.

SCP emerged more than 40 years ago, and its major concepts include rational choice, specificity, opportunity structure, and its 25 prevention techniques. Contrary to the common critique that SCP is atheoretical, it is actually based upon a well-developed interdisciplinary model drawing from criminology, economics, psychology, and sociology. Importantly, a growing number of empirical studies and scientific evaluations have demonstrated SCP’s effectiveness in reducing crime. Finally, the SCP approach inevitably leads to a shifting of responsibility for crime control away from police and on to those entities, public and private, most competent to reduce it.

Nociception is a protective mechanism that mediates behavioral responses to a range of potentially damaging stimuli, including noxious temperature, chemicals, and mechanical stimulation. Nociceptive mechanisms are found throughout metazoans. Noxious stimuli are transduced by specialized, high-threshold peripheral nociceptors, which fire action potentials to elicit adaptive behavioral responses. Nociception is essential for survival and provides a mechanism for sensory perception of noxious stimuli, which alerts the organism to potential environmental dangers. When coupled with pain sensation and complex behavioral responses, this mechanism protects the organism from incipient damage. Moreover, acute and chronic pain may manifest as altered nociception in neuropathic pain states. Elucidating the neural bases of nociception is therefore important for identifying and implementing novel strategies for the treatment of neuropathic pain, as well as uncovering the mechanistic bases by which the nervous system integrates information to produce specific behaviors in response to a range of noxious stimuli. Invertebrate organisms, such as Drosophila melanogaster and Caenorhabditis elegans, have emerged as powerful, genetically tractable platforms for exploring these questions. Here, we concisely review the current state of knowledge regarding the cells, molecules, neural circuits, and behaviors associated with invertebrate nociception in the fruit fly and nematode worm.
Monetary History of East Asia
Authors: Theobald Ulrich
Published: March 2017

East Asian monetary systems were traditionally based on commodity monies, the most famous of which were round copper coins (Cash) with a square central hole, and silver ingots (Tael, from around 1000 ce). While issue of the former was in the hand of the state, silver bars were privately produced and controlled. The Tael nonetheless served as a unit of account also in government ledgers. China was the first nation worldwide to use paper money backed by bullion reserve (c. 1000–1500), but fiat monies were not readily accepted by markets. Gold coins were exclusively used in Japan from circa 1600. With the discovery of Mexican silver, China and Japan became part of the silver-based world economy. Japan adopted the Gold Standard in 1897 and gained access to the world’s financial markets, while China’s currency landscape, even after modernization, remained fragmented and decentralized. With a favorable exchange rate against the US$, Japan recovered after World War II. The US$ devaluation in the Plaza Accord 1985 did not stop that boom. Excessive loans induced the asset price bubble of 1987. In the “lost decade” until 2000, the Bank of Japan pursued a volatile monetary policy, so in 1998 it was necessary to induce liberalization of the banking sector. Reform in the financial sector was also begun in South Korea after the Asian Crisis of 1997. The Chinese policy of Reform and Opening in 1978 first led to inflation and then to undervaluation of the Renminbi (Yuan), which supported the unique economic growth. The currency was made convertible in 1996 and was in 2005 pegged to a basket of foreign currencies. China’s banking system remains underdeveloped and suffers from the burden of indebted state-owned enterprises. China has accumulated huge amounts of foreign exchange. The RMB might become an anchor currency of a financial regionalism.
Latinos in Film
Authors: Serna Laura Isabel
Published: March 2017

Latinos have constituted part of the United States’ cinematic imagination since the emergence of motion pictures in the late 19th century. Though shifting in their specific contours, representations of Latinos have remained consistently stereotypical; Latinos have primarily appeared on screen as bandits, criminals, nameless maids, or sultry señoritas. These representations have been shaped by broader political and social issues and have influenced the public perception of Latinos in the United States. However, the history of Latinos and film should not be limited to the topic of representation. Latinos have participated in the film industry as actors, creative personnel (including directors and cinematographers), and have responded to representations on screen as members of audiences with a shared sense of identity, whether as mexicanos de afuera in the early 20th century, Hispanics in the 1980s and 1990s, or Latinos in the 21st century. Both participation in production and reception have been shaped by the ideas about race that characterize the film industry and its products. Hollywood’s labor hierarchy has been highly stratified according to race, and Hollywood films that represent Latinos in a stereotypical fashion have been protested by Latino audiences. While some Latino/a filmmakers have opted to work outside the confines of the commercial film industry, others have sought to gain entry and reform the industry from the inside. Throughout the course of this long history, Latino representation on screen and on set has been shaped by debates over international relations, immigration, citizenship, and the continuous circulation of people and films between the United States and Latin America.
The United States–Mexico Border
Authors: Alvarez C. J.
Published: March 2017

The region that today constitutes the United States–Mexico borderland has evolved through various systems of occupation over thousands of years. Beginning in time immemorial, the land was used and inhabited by ancient peoples whose cultures we can only understand through the archeological record and the beliefs of their living descendants. Spain, then Mexico and the United States after it, attempted to control the borderlands but failed when confronted with indigenous power, at least until the late 19th century when American capital and police established firm dominance. Since then, borderland residents have often fiercely contested this supremacy at the local level, but the borderland has also, due to the primacy of business, expressed deep harmonies and cooperation between the U.S. and Mexican federal governments. It is a majority minority zone in the United States, populated largely by Mexican Americans. The border is both a porous membrane across which tremendous wealth passes and a territory of interdiction in which noncitizens and smugglers are subject to unusually concentrated police attention. All of this exists within a particularly harsh ecosystem characterized by extreme heat and scarce water.
Childbirth and Breastfeeding in 20th-Century America
Authors: Martucci Jessica
Published: March 2017

By the end of the 19th century, the medical specialties of gynecology and obstetrics established a new trend in women’s healthcare. In the 20th century, more and more American mothers gave birth under the care of a university-trained physician. The transition from laboring and delivering with the assistance of female family, neighbors, and midwives to giving birth under medical supervision is one of the most defining shifts in the history of childbirth. By the 1940s, the majority of American mothers no longer expected to give birth at home, but instead traveled to hospitals, where they sought reassurance from medical experts as well as access to pain-relieving drugs and life-saving technologies. Infant feeding followed a similar trajectory. Traditionally, infant feeding in the West had been synonymous with breastfeeding, although alternatives such as wet nursing and the use of animal milks and broths had existed as well. By the early 20th century, the experiences of women changed in relation to sweeping historical shifts in immigration, urbanization, and industrialization, and so too did their abilities and interests in breastfeeding. Scientific study of infant feeding yielded increasingly safer substitutes for breastfeeding, and by the 1960s fewer than 1 in 5 mothers breastfed. In the 1940s and 1950s, however, mothers began to organize and to resist the medical management of childbirth and infant feeding. The formation of childbirth education groups helped spread information about natural childbirth methods and the first dedicated breastfeeding support organization, La Leche League, formed in 1956. By the 1970s, the trend toward medicalized childbirth and infant feeding that had defined the first half of the century was in significant flux. By the end of the 20th century, efforts to harmonize women’s interests in more “natural” motherhood experiences with the existing medical system led to renewed interest in midwifery, home birth, and birth centers. Despite the cultural shift in favor of fewer medical interventions, rates of cesarean sections climbed to new heights by the end of the 1990s. Similarly, although pressures on mothers to breastfeed mounted by the end of the century, the practice itself increasingly relied upon the use of technologies such as the breast pump. By the close of the century, women’s agency in pursuing more natural options proceeded in tension with the technological, social, medical, and political systems that continued to shape their options.
