The role of high school racial composition and opportunities to learn in students' STEM college participation
Authors: Bottia Martha Cecilia , Mickelson Roslyn Arlin , Giersch Jason , Stearns Elizabeth , Moller Stephanie 
Published: November 2017

AbstractWe analyze longitudinal data from students who spent their academic careers in North Carolina (NC) public secondary schools and attended NC public universities to investigate the importance of high school racial composition and opportunities to learn in secondary school for choosing a science, technology, engineering, and mathematics (STEM) major. We consider school racial composition and opportunities to learn as contexts that shape students' decisions regarding college majors. Results of cross‐classified hierarchical logistic models indicate that attending schools with predominantly White students is negatively associated with declaring a STEM major and with graduating with a STEM major irrespective of students' own race. The finding suggests that for students in North Carolina, attending racially isolated White high schools is related to a decrease in adolescents' participation in STEM during college.
The influence of instruction, prior knowledge, and values on climate change risk perception among undergraduates

Published: November 2017

AbstractWe evaluated influences on the climate change risk perceptions of undergraduate students in an introductory Earth Science course. For this sample, domain‐specific content knowledge about climate change was a significant predictor of students' risk perception of climate change while cultural worldviews (individualism, hierarchy) and political orientation were not. These results contrast with previous studies highlighting worldviews as a dominant influence on risk perception. At the beginning of the semester, students' climate change content knowledge was relatively low, with average scores on a 21‐item test less than 50%. Post instruction results indicated that students learned climate change science during the course, and their perceptions of risks associated with climate change increased. Unlike most prior research evaluating links between climate change knowledge and risk perception, our measure of content knowledge was a validated assessment specific to climate change. Use of this specific climate knowledge test may be one reason that we detected a relationship between climate knowledge and risk perception whereas most of the previous research has not. Another—possibly complementary—explanation may be a generational shift between our study sample and prior samples. Undergraduates today, having grown up with more exposure to climate change in schools and the media than previous generations, may be diverging from average adults in that learning climate science appears to also increase their perceptions of the risks climate change poses. Undergraduate courses with embedded climate‐related activities present an opportunity to both increase climate science knowledge and risk perceptions of future decision makers.
The roles of parenting practices, sociocognitive/emotive traits, and prosocial behaviors in low‐income adolescents
Authors: Davis Alexandra N. , Carlo Gustavo 
Published: November 2017

ABSTRACTThe goal of the current study was to examine the links among parenting practices (i.e., use of social and material rewards), sociocognitive and socioemotive traits (i.e., perspective taking, prosocial moral reasoning, and empathic concern), and prosocial behaviors among adolescents in a low‐income, Midwestern community. Participants were 311 adolescents (M age = 16.10 years; range = 14–19 years; 58.7% girls; 82.7% White; 13.6% Latino). The results demonstrated that social rewards were positively associated with perspective taking, empathic concern, and prosocial moral reasoning, which were each associated with multiple forms of prosocial behaviors. Material rewards were negatively associated with prosocial moral reasoning and empathic concern. There were also direct links between material and social rewards and prosocial behaviors. Discussion will focus on the intervening role of social cognitions and emotions in explaining links between parenting practices and low‐income adolescents' prosocial behaviors.
The relationship of school climate, teacher defending and friends on students' perceptions of bullying in high school

Published: November 2017

ABSTRACTThe purpose of this study was to examine the relationship of school climate, teacher defending, and friends on bullying and victimization. Participants were 2273 high school students from 3 public schools (an all girls, all boys boarding, and a co‐ed day) in Kenya. A structural equation model was used to examine relationships between school climate, teacher behavior toward bullying, and student demographic characteristics, and bullying. Results revealed that a positive school climate was associated with less bullying behavior and victimization. In addition, when students reported that teachers stop bullying by students, bullying behavior and victimization scores were lower. Contrary to previous research these results showed that residents of a boys only boarding school were less likely to report bullying behavior than residents of an all girls school, or students at a co‐educational institution. Furthermore, there were no differences in bullying behavior or victimization by gender or grade level. Implications of these results are discussed.
Adaptive terminal guidance law with impact-angle constraint
Authors: Gao C. , Li J. , Feng T. , Jing W. 
Published: November 2017

ABSTRACTThis paper proposes an adaptive guidance law for attacking a ground target based on motion camouflage strategy. The coefficients of normal and bi-normal feedback guidance law are given according to the relative motion relationship under Frenet frame. Utilizing the coefficients, the motion camouflage proportional guidance law is derived. In order to improve the initial overload characteristic of the missile, an adaptive feedback coefficient is introduced. Then, the adaptive guidance law is applied to a longitudinal plane interception problem with impact-angle constraint. Finally, the validity of this guidance law for air-to-ground missiles is proved by simulations.
Riemann solution for a class of morphodynamic shallow water dam-break problems
Authors: Zhu Fangfang , Dodd Nicholas 
Published: November 2017

This paper investigates a family of dam-break problems over an erodible bed. The hydrodynamics is described by the shallow water equations, and the bed change by a sediment-conservation equation, coupled to the hydrodynamics by a sediment transport (bed-load) law. When the initial states $\boldsymbol{U}_{l}$ and $\boldsymbol{U}_{r}$ are sufficiently close to each other the resulting solutions are consistent with the theory proposed by Lax (Hyperbolic Systems of Conservation Laws and the Mathematical Theory of Shock Waves, 1973, SIAM), that for a Riemann problem of $n$ equations there are $n$ waves associated with the $n$ characteristic families. However, for wet–dry dam-break problems over a mobile bed, there are three governing equations, but only two waves. One wave vanishes because of the presence of the dry bed. When initial left and right bed levels ($B_{l}$ and $B_{r}$) are far apart, it is shown that a semi-characteristic shock may occur, which happens because, unlike in shallow water flow on a fixed bed, the flux function is non-convex. In these circumstances it is shown that it is necessary to reconsider the usual shock conditions. Instead, we propose an implied internal shock structure the concept of which originates from the fact that the stationary shock over a fixed-bed discontinuity can be regarded as a limiting case of flow over a sloping fixed bed. The Needham & Hey (Phil. Trans. R. Soc. Lond. A, vol. 334, 1991, pp. 25–53) approximation for the ambiguous integral term $\int \!h\,\text{d}B$ in the shock condition is improved based on this internal shock structure, such that mathematically valid solutions that incorporate a morphodynamic semi-characteristic shock are arrived at.
Tensor geometry in the turbulent cascade
Authors: Ballouz Joseph G. , Ouellette Nicholas T. 
Published: November 2017

The defining characteristic of highly turbulent flows is the net directed transport of energy from the injection scales to the dissipation scales. This cascade is typically described in Fourier space, obscuring its connection to the mechanics of the flow. Here, we recast the energy cascade in mechanical terms, noting that for some scales to transfer energy to others, they must do mechanical work on them. This work can be expressed as the inner product of a turbulent stress and a rate of strain. But, as with all inner products, the relative alignment of these two tensors matters, and determines how strong the energy transfer will be. We show that this tensor alignment behaves very differently in two and three dimensions; in particular, the tensor eigenvalues affect the inner product in very different ways. By comparing the observed energy flux to the maximum possible if the tensors were in perfect alignment, we define an efficiency for the energy cascade. Using data from a direct numerical simulation of isotropic turbulence, we show that this efficiency is perhaps surprisingly low, with an average value of approximately 25 % in the inertial range, although it is spatially heterogeneous. Our results have implications for how the stress and strain-rate magnitudes influence the flux of energy between scales, and may help to explain why the energy cascades in two and three dimensions are different.

AbstractThe aim of this study was to evaluate the impact of a non-restrictive satiating diet in men displaying various degrees of satiety efficiency. In all, sixty-nine obese men aged 41·5 (sd5·7) years were randomly assigned to a control (10–15, 55–60 and 30 % energy as protein, carbohydrate and lipid, respectively;n34) or satiating (20–25, 45–50 and 30–35 % energy as protein, carbohydrate and lipid, respectively;n35) diet for 16 weeks, and were classified as having a low (LSP) or high (HSP) satiety phenotype. Both diets were consumedad libitum. Changes in body weight, BMI, percent fat mass, waist circumference, satiety responsiveness and eating behaviour traits were assessed following the intervention. Dropout rates were higher in the control diet (44·1 %) compared with the satiating diet (8·6 %). Decreases in body weight, BMI and waist circumference were significant in both groups, yet HSP individuals lost more body weight than LSP individuals (P=0·048). Decreases in % fat mass were greater in the satiating diet (LSP: −2·1 (sd2·1) %;P<0·01 and HSP: −3·0 (sd2·5) %;P<0·001) compared with the control diet (LSP: −1·1 (sd2·5) % and HSP: −1·3 (sd2·6) %) (P=0·034). Satiety responsiveness was markedly improved in the satiating diet, whereas no significant changes were observed in the control group. Changes in dietary restraint (+3·3 (sd2·9) to +7·2 (sd5·5)), flexible control (+0·9 (sd1·4) to +2·3 (sd2·7)), rigid control (+2·2 (sd1·5) to +2·5 (sd2·8)), disinhibition (−2·8 (sd3·7) to −3·2 (sd2·6)) and susceptibility to hunger (−2·7 (sd4·1) to −4·6 (sd3·9)) were similar between the diets. Compared with the control diet, the satiating diet favoured adherence, decreased % fat mass and improved satiety responsiveness in both HSP and LSP individuals.
The elusive constellations of poverty
Authors: Breugelmans Seger M. , Plantinga Arnoud , Zeelenberg Marcel , Poluektova Olga , Efremova Maria 
Published: November 2017

AbstractPepper & Nettle describe possible processes underlying what they call a behavioral constellation of deprivation (BCD). Although we are certain about the application of evolutionary models to our understanding of poverty, we are less certain about the utility of behavioral constellations. The empirical record on poverty-related behaviors is much more divergent and broad than such constellations suggest.
From perceived control to self-control, the importance of cognitive and emotional resources
Authors: Carmel Eyal , Leiser David 
Published: November 2017

AbstractPepper & Nettle (P&N) suggest that the poor present a “contextually appropriate response” to a perceived limited control and to a short life expectancy. We argue that differences in health, behavior, or impaired economic decisions are better explained by self-control. We discuss the implications of the differences between these perspectives and present supporting findings from two intervention studies with marginalized populations.
Evolutionary approaches to deprivation transform the ethics of policy making
Authors: Chevallier Coralie 
Published: November 2017

AbstractWhen designing public policies, decision makers often rely on their own behavioral preferences. Pepper & Nettle's (P&N's) theory suggests that these preferences are unlikely to be appropriate when applied to a different environment (e.g., a low-income environment with fewer career opportunities). This theory has profound implications for the design and ethics of public policies.
When does deprivation motivate future-oriented thinking? The case of climate change
Authors: Pearson Adam R. , van der Linden Sander 
Published: November 2017

AbstractPepper & Nettle overstate cross-domain evidence of present-oriented thinking among lower-socioeconomic-status (SES) groups and overlook key social and contextual drivers of temporal decision making. We consider psychological research on climate change – a quintessential intertemporal problem that implicates inequities and extrinsic mortality risk – documenting more future-oriented thinking among low- compared to high-SES groups.
Loss of control is not necessary to induce behavioral consequences of deprivation: The case of religious fasting during Ramadan
Authors: Rad Mostafa Salari , Ginges Jeremy 
Published: November 2017

AbstractPepper & Nettle argue that the more present-oriented behavior associated with a low socioeconomic status is an adaptive response to having relatively little control over the future. However, a study of fasters during Ramadan shows that self-imposed deprivation, which carries no implications regarding the ability to realize deferred rewards, is associated with loss and risk aversion.
Intertemporal impulsivity can also arise from persistent failure of long-term plans
Authors: Srivastava Nisheeth , Srinivasan Narayanan 
Published: November 2017

AbstractWe suggest that steep intertemporal discounting in individuals of low socioeconomic status (SES) may arise as a rational metacognitive adaptation to experiencing planning and control failures in long-term plans. Low SES individuals' plans fail more frequently because they operate close to budgetary boundaries, in turn because they consistently operate with limited budgets of money, status, trust, or other forms of social utility.
Epigenetic-based hormesis and age-dependent altruism: Additions to the behavioural constellation of deprivation
Authors: Brown William Michael , Olding Rose Jyoti 
Published: November 2017

AbstractWe support Pepper and Nettle's (P&N's) hypothesised adaptive responses to deprivation. However, we argue that adaptive responses to stress shift with age. Specifically, present-oriented behaviours are adaptive for young people (e.g., in terms of mating and reproduction) but costly for older people in deprived communities who would benefit from investing in grandchildren. Epigenetic mechanisms may be responsible for age-related tactical shifts.
Orange is the new aesthetic
Authors: Chatterjee Anjan 
Published: November 2017

AbstractThe Distancing-Embracing model proposes that negative emotions are constitutive of aesthetic experiences. This move is welcome and adds depth to empirical aesthetics. However, the model's emphasis on temporality challenges how best to think of static art forms. I suggest that “decisive” and “distilled” moments dilate time in the viewer's mind and might allow the model to accommodate photography and painting.
Distancing, not embracing, the Distancing-Embracing model of art reception
Authors: Davies Stephen 
Published: November 2017

AbstractDespite denials in the target article, the Distancing-Embracing model appeals to compensatory ideas in explaining the appeal of artworks that elicit negative affect. The model also appeals to the deflationary effects of psychological distancing. Having pointed to the famous rejection in the 1960s of the view that aesthetic experience involves psychological distancing, I suggest that “distance” functions here as a weak metaphor that cannot sustain the explanatory burden the theory demands of it.
Individual differences in embracing negatively valenced art: The roles of openness and sensation seeking
Authors: Fayn Kirill , Kuppens Peter 
Published: November 2017

AbstractWe elaborate on the role of individual differences in the processing mechanisms outlined by the Distancing-Embracing model. The role of openness is apparent in appreciating meaning-making art that elicits interest, feeling moved, and mixed emotions. The influence of sensation seeking is likely to manifest in thrill-chasing art that draws on the arousing interplay of positive and negative emotions.
Fiction as a bridge to action
Authors: Green Melanie C. , Fitzgerald Kaitlin 
Published: November 2017

AbstractWe propose an extension of the Distancing-Embracing model to the use of stories for prosocial ends. Specifically, audiences may find stories of individuals in need too emotionally overwhelming. Audiences may attempt to regulate or reduce negative emotions, which can reduce empathy and willingness to help. Through distancing, fictionalized accounts may counteract this tendency and thus increase prosocial behavior.
Psychological models of art reception must be empirically grounded
Authors: Nadal Marcos , Vartanian Oshin , Skov Martin 
Published: November 2017

AbstractWe commend Menninghaus et al. for tackling the role of negative emotions in art reception. However, their model suffers from shortcomings that reduce its applicability to empirical studies of the arts: poor use of evidence, lack of integration with other models, and limited derivation of testable hypotheses. We argue that theories about art experiences should be based on empirical evidence.
Parental response to baby cry involves brain circuits for negative emotion Distancing-Embracing
Authors: Swain James E. , Ho S. Shaun 
Published: November 2017

AbstractThe “art form” of parent-infant bonding critically involves baby conveying negative emotions – literally compelling parents to respond and provide care. Current research on the brain basis of parenting is combining brain imaging with social, cognitive, and behavioral analyses to understand how parental brain circuits regulate thoughts and behavior in mental health, risk, and resilience. Understanding the parental brain may contribute to solving the long-standing paradox of self-sought hedonic exposure to negative emotions in art reception.
The causal power of securitisation: an inquiry into the explanatory status of securitisation theory illustrated by the case of Somali piracy
Authors: Oliveira Gilberto Carvalho 
Published: November 2017

AbstractThis article joins the nascent debate on the causal status of securitisation theory. Relying on critical realist’s efforts to deepen and broaden the concept of cause – defined as ‘causal complex’ – and its insights to integrate discourse and constitutive relations into a non-positivist framework for causal explanation, the article aims to explore the explanatory status of securitisation theory, without downgrading its discursive core. To illustrate this argument, the article uses the securitisation of Somali piracy as an example of how the causal analysis of securitisation can contribute to explain some of the dynamics involved in security governance. From this perspective, securitisation works within a broader empirical framework of security, significantly implicated in causal relations, going beyond the Copenhagen School’s conception of securitisation as a non-causal constitutive theory merely defined as a formal framework for analysis. The article discusses, finally, the relevance and implications of introducing causal analysis in the study of securitisation.
Prolonged prostaglandin-E2-associated periosteal reaction and elevated C-reactive protein levels
Authors: Duggan Maria I. , MacLaren Andrew T. , Anand Dhullipala 
Published: November 2017

AbstractThis is a case review of two infants who received a prolonged course of prostaglandin-E2 therapy for congenital cardiac lesions while awaiting corrective surgery. These cases highlight an association between prolonged prostaglandin-E2 therapy with periosteal reactions and elevated C-reactive protein levels. Failure to recognise this association may lead to multiple courses of antibiotics for presumed sepsis and further prolongation of prostaglandin-E2 therapy.
Glyphosate plus 2,4-D Deposition, Absorption, and Efficacy on Glyphosate-Resistant Weed Species as Influenced by Broadcast Spray Nozzle
Authors: Legleiter Travis R. , Young Bryan G. , Johnson William G. 
Published: November 2017

AbstractThe introduction of 2,4-D–resistant soybean will provide an additional POST herbicide site of action for control of herbicide-resistant broadleaf weeds. The introduction of this technology also brings concern of off-site movement of 2,4-D onto susceptible crops such as sensitive soybean and tomato. The 2,4-D formulation approved for use in 2,4-D–resistant soybean restricts application of the herbicide to nozzles that produce very coarse to ultra-coarse droplet spectrums. The use of larger droplet spectrums for broadcast applications can reduce herbicide deposition onto target weeds and thus influence herbicide efficacy. Field experiments were conducted to evaluate the influence of nozzle design on herbicide deposition onto target plants and the resulting efficacy of a POST application of 280 g ha−1glyphosate plus 280 g ha−12,4-D. The TTI11004 nozzle produced an ultra-coarse droplet spectrum and reduced coverage and deposition density on spray cards as compared with the XR11004 and TT11004 nozzles that produced medium droplet spectrums. The AIXR11004 nozzle also reduced deposition density on spray cards but did not reduce coverage. Herbicide solution deposition onto glyphosate-resistant Palmer amaranth, tall waterhemp, giant ragweed, and horseweed ranged from 0.28 to 0.72 µl cm−2and was not influenced by nozzle design. Herbicide efficacy was reduced by the TTI11004 nozzle on Palmer amaranth and horseweed compared with the AIXR11004, TT11004, and XR11004 nozzles when applications were made to either high densities of plants or plants exceeding the labeled height. The use of the AIXR11004 and TTI11004 nozzles that are listed as approved nozzles for glyphosate plus 2,4-D applications on 2,4-D–resistant soybean did not reduce herbicide deposition onto four of the most troublesome broadleaves and did not reduce herbicide efficacy when applied in conjunction with lower weed densities and smaller weeds.
