Empathy as a neuropsychological heuristic in social decision-making

Decision-making in social dilemmas is suggested to rely on three factors: the valuation of a choice option, the relative judgment of two or more choice alternatives, and individual factors affecting the ease at which judgments and decisions are made. Here, we test whether empathy—an individual’s relative ability to understand others’ thoughts, emotions, and intentions—acts as an individual factor that alleviates conflict resolution in social decision-making. We test this by using a framed, iterated prisoners’ dilemma (PD) game in two settings. In a behavioral experiment, we find that individual differences in empathic ability (the Empathy Quotient, EQ) were related to lower response times in the PD game, suggesting that empathy is related to faster social choices, independent of whether they choose to cooperate or defect. In a subsequent neuroimaging experiment, using functional magnetic resonance imaging, we find that EQ is positively related to individual differences in the engagement of brain structures implemented in mentalizing, including the precuneus, superior temporal sulcus, and dorsolateral prefrontal cortex. These results suggest that empathy is related to the individual difference in the engagement of mentalizing in social dilemmas and that this is related to the efficiency of decision-making in social dilemmas.
Violence, Sex, Race, and Age in Popular Video Games: A Content Analysis.

After dinner in a suburban American home, a 13-year-old boy plays a video game alone in his bedroom. On the screen, the boy's hero, Duke Nukem, approaches a strip club where, before entering, he guns down the local authorities. Duke is a young, White man—blond and tan, with huge, rippling muscles. On entering the club, he sees several virtually naked young women dancing on poles, moaning and gyrating. He shoots and kills one of the young women. As her screams fade, Duke fires his witty retort, "Too bad, she was cute. "
Does being a Stranger make it Difficult to Cooperate?

Abstract Competition and cooperation are two somewhat opposed strategies for interpersonal social interaction that help us to achieve both individual and shared goals. The main aim of this study was to explore which type of social interaction (cooperative or competitive) is more stressful in a face-to-face same-sex dyad in healthy young participants (n = 178), considering outcome obtained in these tasks (positive or negative) and sex as moderating variables, and performance of the task alone as a control condition. Salivary cortisol (Csal) was measured in one sample obtained before task and four obtained after the task (+0, +15, +30 and +45 minutes after). Anxiety-state was assessed before and immediately after the task. Participants who cooperated and obtained negative outcomes had higher Csal levels than those who worked alone with negative outcomes in all periods after the task (p = .008, η p 2 = .058 and p = .033, η p 2 = .031, respectively). Moreover, those who cooperated showed higher mean self-reported state anxiety levels than the rest of the participants (p = .013, η p 2 = .051 and p < .001, η p 2 = .530, respectively). Our study indicates that cooperation between strangers in face-to-face dyads is highly stressful, more so than competing or working alone. These results should be taken into account for understanding situations of social stress and can be generalized to situations in which subjects cooperate or must decide between cooperating and competing to attain a goal.
Increases in plasma levels of atrial and brain natriuretic peptides after running a marathon: are their effects partly counterbalanced by adrenocortical steroids?

OBJECTIVE Long-distance running results in considerable stress. Little evidence exists about the role of the atrial and brain natriuretic peptides, ANP and BNP, deriving from the myocardium. The aim of our study was to investigate the influence of running 42.195 km on changes in circulating natriuretic propeptides and adrenocortical steroids. DESIGN AND METHODS We studied 17 male and 2 female runners (age: 28-62 Years) participating in a marathon. Blood samples were obtained before and immediately after the competition. proANP(1-98) and proANP(1-30) as well as Nt-proBNP(8-29) were determined by enzyme immunoassays. RESULTS Runners finished the competition between 2 h 58 min and 4 h 25 min. We observed a more pronounced increase in proANP(1-98) (+58%) and proANP(1-30) (+99%, both P<0.001) compared with Nt-proBNP(8-29) (+6%; P=0.005). Increases in proANP(1-30) positively correlated with runners' age (r=0.53; P=0.02). We also observed a marked increase in cortisol (+73%) and especially in aldosterone (+431%, both P<0.001). CONCLUSIONS Cardiac strain during long-distance running may explain the pronounced increase in proANP. Other explanations for the observed rise in plasma levels might be a change in the permeability of myocardial cells and an impaired clearance. A rise in adrenocortical steroids may compensate for the negative influence of ANP on natriuresis and blood pressure. Positive effects of ANP during a marathon could be the regulation of body temperature by influencing sweat glands as well as the stimulation of lipolysis compensating for the enormous energy demand.
Disruptive Nocturnal Behavior in Parkinson's Disease and Alzheimer's Disease

Disruptive nocturnal behavior, often referred to as sundowning, is a commonly encountered clinical problem in most forms of dementia. This study compared disruptive nocturnal behavior in patients with Alzheimer's disease (AD) and Parkinson's disease (PD). Questionnaire data were collected from 60 AD and 48 PD caregivers. Respondents were asked to record the typical time of day when any of seven disruptive behaviors were evidenced in their patients, if at all. Two scores were computed: (1) a sundowning score (number of nocturnal disruptive behaviors, range 0–7), and (2) a total score (number of disruptive behaviors without regard to time, range 0–7). Results indicated PD patients were more likely than AD patients to exhibit disruptive nocturnal behavior. The dose, timing, or number of years on antiparkinsonian medication were not related to nocturnal disruptive behavior within the PD patient group. These findings raise the possibility that sundowning in PD patients may be a manifestation of dopaminergic depletion within the basal ganglia or other abnormalities involving the cholinergic, serotoninergic and/or noradrenergic systems in the brainstem.
Forward spreading in the establishment of a vertebrate Hox expression boundary: The expression domain separates into anterior and posterior zones, and the spread occurs across implanted glass barriers

By use of wholemount in situ hybridization, we show how expression of the chicken homeobox gene Hoxd‐4 commences in the posterior part of the primitive streak and then spreads forward, covering most of the primitive streak by the 2 somite stage, covering the entire primitive streak by the 5 somite stage, reaching the somite 1/somite 2 level of the neural tube by the 9 somite stage, and reaching the rhombomere 6/rhombomere 7 junction of the hindbrain by the 15 somite stage. Forward spreading does not depend upon cell migration, as was evidenced by vital dye (DiI) cell marking experiments. Furthermore, forward spreading does not apparently require tissue continuity since it could not be blocked by impermeable (glass) barriers surgically implanted to divide embryonic tissues. As forward spreading of chick Hoxd‐4 proceeds, the domain of expression separates, at late primitive streak stages, into “anterior” and “posterior zones,” with an intervening “intermediate zone” of weak or non‐expression. Clear anterior and posterior zones were also found for Hoxa‐3 and a‐4 expression in late primitive steak stage mouse embryos. We present evidence that the anterior zone corresponds with the “definitive” domain of Hox gene expression, as has earlier been extensively characterized in midgestation embryos. The posterior zone is transitory, probably persisting only for the duration of the primitive streak, and it is a region of intense Hox expression in primitive streak tissue, Hensen's node, and adjacent regions of neurectoderm and mesoderm. We suggest that the posterior zone marks the source of a morphogen which is the primary activator of Hox gene expression, and we discuss possible models for the mechanism of forward spreading in expression. © 1994 Wiley‐Liss, Inc.
Robotic/virtual reality intervention program individualized to meet the specific sensorimotor impairments of an individual patient: a case study

Abstract A majority of studies examining repetitive task practice facilitated by robots for the treatment of upper extremity paresis utilize standardized protocols applied to large groups. This study will describe a virtually simulated, robot-based intervention customized to match the goals and clinical presentation of a gentleman with upper extremity hemiparesis secondary to stroke. MP, the subject of this case, is an 85-year-old man with left hemiparesis secondary to an intracerebral hemorrhage 5 years prior to examination. Outcomes were measured before and after a 1-month period of home therapy and after a 1-month virtually simulated, robotic intervention. The intervention was designed to address specific impairments identified during his PT examination. When necessary, activities were modified based on MP’s response to his first week of treatment. MP’s home training program produced a 3-s decline in Wolf Motor Function Test (WMFT) time and a 5-s improvement in Jebsen Test of Hand Function (JTHF) time. He demonstrated an additional 35-s improvement in JTHF and an additional 44-s improvement in WMFT subsequent to the robotic training intervention. A 24-h activity measurement and the Hand and Activities of Daily Living scales of the Stroke Impact Scale improved following the robotic intervention. Based on his responses to training we feel that we have established that a customized program of virtually simulated, robotically facilitated rehabilitation was feasible and resulted in larger improvements than an intensive home training program in several measurements of upper extremity function in our patient with chronic hemiparesis.
Revealing the hidden complexities of mtDNA inheritance

Mitochondrial DNA (mtDNA) is a pivotal tool in molecular ecology, evolutionary and population genetics. The power of mtDNA analyses derives from a relatively high mutation rate and the apparent simplicity of mitochondrial inheritance (maternal, without recombination), which has simplified modelling population history compared to the analysis of nuclear DNA. However, in biology things are seldom simple, and advances in DNA sequencing and polymorphism detection technology have documented a growing list of exceptions to the central tenets of mitochondrial inheritance, with paternal leakage, heteroplasmy and recombination now all documented in multiple systems. The presence of paternal leakage, recombination and heteroplasmy can have substantial impact on analyses based on mtDNA, affecting phylogenetic and population genetic analyses, estimates of the coalescent and the myriad of other parameters that are dependent on such estimates. Here, we review our understanding of mtDNA inheritance, discuss how recent findings mean that established ideas may need to be re‐evaluated, and we assess the implications of these new‐found complications for molecular ecologists who have relied for decades on the assumption of a simpler mode of inheritance. We show how it is possible to account for recombination and heteroplasmy in evolutionary and population analyses, but that accurate estimates of the frequencies of biparental inheritance and recombination are needed. We also suggest how nonclonal inheritance of mtDNA could be exploited, to increase the ways in which mtDNA can be used in analyses.
Factors affecting hotel employees’ perception and attitude toward empowerment

ABSTRACT The objective of this research was to identify and examine the factors affecting Greek hotel employees’ perception and attitudes toward empowerment. To achieve the aforementioned objective primary research was conducted among the employees of a big hotel group. Factor analysis was applied to determine a principal factor and its main components, thus allowing the measurement of human resources attitude and perception toward empowerment. At the next stage, the said factor was checked as to its correlation on the one hand with the sense of the employees about their jobs and on the other hand with the satisfaction they draw from them.
The “L” Word

In recent years, the electorate has sorted along ideological lines. Republican identifiers have grown more likely to self-identify as conservatives. Democrats, however, have been slow to embrace the liberal label. And while many Americans are operationally liberal and express support for liberal policy positions, in symbolic terms, the American electorate is much more conservative in nature and appears reluctant to hew to the liberal label. The uneven nature of partisan sorting and the observed symbolic/operational divide have both been linked to Republican efforts at making “liberal” a dirty word, but researchers have yet to offer a direct test of the effects of exposure to anti-liberal rhetoric. In this study, I rectify this shortcoming using the 2004 University of Wisconsin-Madison (UW)/Brigham Young University (BYU) panel study coupled with data on the content of candidates’ campaign advertising from the Wisconsin Advertising Project. I find that exposure to anti-liberal campaign messages had a direct effect on evaluations of Democratic candidates, vote intention, and vote choice, but only in senate races. At the same time, self-identified ideology was unmoved by elite efforts at disparaging the liberal label—thereby calling into question simple versions of a common explanation for the existence of conservative Democrats and “conflicted” conservatives.
Cumulative Prospect Theory and Momentum Crashes: Evidence from Asia

We provide robust evidence of momentum crashes within the Asian region, which occurred following the Asian financial crisis and the global financial crisis. The probability of a momentum crash is time-varying; it increases after periods of low market returns and high cross-sectional return dispersion when the beta of the zero-investment momentum portfolio becomes negative. Under cumulative prospect theory, investors overweight the probability of a momentum crash when estimating their value function, resulting in the price of “winners” decreasing and future average returns increasing. Consistent with this theory, we show that momentum returns in Asia are substantially lower following periods where the probability of a momentum crash is higher. Therefore, we argue that the negative (positive) skewness of winner (loser) portfolios is priced and may explain the momentum premium.
Experimental dSPACE verification of fuzzy compensator of windup problem in sensorless direct torque control of induction motor

It is well known that the windup problem is one of the most serious problems which degrades the closed loop performances, especially in sensorless induction motor drive. In this regards, and in order to improve the performance, this paper proposes a fuzzy compensator to prevent the windup problem in sensorless Direct Torque Control of induction motor, which is a common application in industrial process. The approach treated in this work has been performed experimentally in Real Time using a DSP-based development board from Texas Instrument, and investigation gave results that justify the claims.
Influence of Surgeon Volume on Inpatient Complications, Cost, and Length of Stay Following Total Ankle Arthroplasty

Background: Increased surgeon volume may be associated with improved outcomes following operative procedures. However, there is a lack of information on the effect of surgeon volume on inpatient adverse events and resource utilization following total ankle arthroplasty (TAA). Methods: A retrospective cohort study of TAA patients was performed using the Nationwide Inpatient Sample (NIS) from 2003 to 2009. High-volume surgeons were considered as those with volume ≥90th percentile of surgeons performing TAA. Multivariate regression was used to compare the rates of adverse events, hospital length of stay, and total hospital charges between surgeon volume categories. Results: A total of 4800 TAA patients were identified. The 90th percentile for surgeon volume was 21 cases per year. Mean length of stay was 2.8 ± 2.3 days and mean hospital charges were $45 963 ± $43 983. On multivariate analysis, high-volume surgeons had decreased overall complications (OR 0.5, P = .034) and rate of medial malleolus fracture (OR 0.1, P = .043), decreased length of stay (–0.9 days, P < .001), and decreased hospital charges (–$20 904, P < .001). Conclusions: Surgeons with volume ≥90th percentile had a decreased rate of complications, decreased length of stay, and reduced hospital charges compared to other surgeons. Level of Evidence: Level III, comparative study.
Effects of Cash Transfers on Community Interactions: Emerging Evidence

Abstract This article examines evidence of the effects of national cash transfer programmes on community interactions and discusses the transformative potential of such programmes. The findings indicate positive effects of social transfers on strengthening ‘bonding’ social capital and on breaking patterns of exclusion, but also point to negative effects, particularly in fuelling intra-community tensions and generating feelings of unfairness resulting – for the most part – from targeting-related issues. Evidence remains limited on the formation of ‘bridging’ and ‘linking’ social capital and on the development of mobilisation processes to drive broader processes of social transformation and changes in the status quo.
Testing gradual and speciational models of evolution in extant taxa: the example of ratites

Abstract Ever since Eldredge and Gould proposed their model of punctuated equilibria, evolutionary biologists have debated how often this model is the best description of nature and how important it is compared to the more gradual models of evolution expected from natural selection and the neo‐Darwinian paradigm. Recently, Cubo proposed a method to test whether morphological data in extant ratites are more compatible with a gradual or with a speciational model (close to the punctuated equilibrium model). As shown by our simulations, a new method to test the mode of evolution of characters (involving regression of standardized contrasts on their expected standard deviation) is easier to implement and more powerful than the previously proposed method, but the Mesquite module comet (aimed at investigating evolutionary models using comparative data) performs better still. Uncertainties in branch length estimates are probably the largest source of potential error. Cubo hypothesized that heterochronic mechanisms may underlie morphological changes in bone shape during the evolution of ratites. He predicted that the outcome of these changes may be consistent with a speciational model of character evolution because heterochronic changes can be instantaneous in terms of geological time. Analysis of a more extensive data set confirms his prediction despite branch length uncertainties: evolution in ratites has been mostly speciational for shape‐related characters. However, it has been mostly gradual for size‐related ones.
Between Two Empires

The incarceration of Japanese Americans has been discredited as a major blemish in American democratic tradition. Accompanying this view is the assumption that the ethnic group held unqualified allegiance to the United States. Between Two Empires probes the complexities of prewar Japanese America to show how Japanese in America held an in-between space between the United States and the empire of Japan, between American nationality and Japanese racial identity.
Work disability in inflammatory bowel disease patients 10 years after disease onset: results from the IBSEN Study

Objective To compare the work disability (WD) rate in inflammatory bowel disease (IBD) patients 10 years after disease onset, with the WD rate in the background population,and to assess whether clinical or demographic factors in the early disease course could predict WD after 10 years disease. Design A large, population-based inception cohort (the Inflammatory Bowel in South Eastern Norway cohort) was prospectively followed up at 1, 5 and 10 years after diagnosis. At the 10-year follow-up data on WD were collected. Data on disability pension (DP) in the background population were retrieved from public databases. We calculated overall and age-standardised relative risks (RR) for DP. Logistic regression analysis was used to examine predictive factors. Results A total of 518 patients completed the 10-year follow-up (response rate 83.5%). The overall disability rate in the IBD population was 18.8%, and the RR was 1.8 (95% CI 1.4 to 2.3) for ulcerative colitis (UC) and 2.0 (95% CI 1.4 to 2.7) for Crohn's disease (CD). The RR for DP was highest in patients aged below 40 years while patients aged over 60 years had no increased RR. Steroid treatment at the 1-year follow-up predicted WD after 10 years disease in both CD and UC. In UC, increased C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) at diagnosis, early colectomy, and more than two relapses during the first year of the disease also predicted WD. Conclusion Ten years after disease onset IBD patients had an increased RR for DP as compared with the background population. The youngest patients had the highest RR. Markers of severe disease course predicted WD.
Wear Reduction for Hydropower Turbines Considering Frequency Quality of Power Systems: A Study on Controller Filters

Nowadays, the wear and tear of hydropower turbines is increasing, due to more regulation movements caused by the increasing integration of intermittent renewable energy sources. In this paper, a controller filter is proposed as a solution to the tradeoff between reducing the wear of turbines and maintaining the regulation performance and thereby the frequency quality of the power systems. The widely used dead zone is compared with a floating dead zone and a linear filter, by time-domain simulation and frequency-domain analysis. Simulink models are built and compared with onsite measurement. Then, the time-domain simulation is used to investigate the guide vane movement, the load disturbance and the power system frequency, based on a one-day grid frequency data measured in this study. In the theoretical analysis, the describing functions method and the Nyquist criterion are adopted to examine the stability of the system with different filters. The results show that the floating dead zone, especially the one after the controller, has a better performance than the dead zone on both the wear reduction and frequency quality. The linear filter has a relatively weak impact on both guide vane movements and the frequency quality. Other related conclusion and understandings are also obtained.
