Previous studies investigating to what extent students in elementary schools defend their victimized classmates typically treated defending as an individual characteristic. Defending should, however, be seen as a directed dyadic relationship between a victim and a defender, who are embedded multiple positive and negative relationships with each other and their classmates. Accordingly, in the present study defending was investigated using social network analysis. More specifically, it was investigated to what extent defending relationships co-occurred with friendship and dislike relationships involving not only the victim and the defender but also other classmates. Bivariate Exponential Random Graph Models (ERGMs) were used to analyze the defending-friendship and defending-dislike relationships in seven grade-three classrooms. As hypothesized, the results indicated that victimized students were likely to be defended by students who they perceive as friends or who perceive them as friends. Moreover, defending was likely to occur when the victim and (potential) defender had the same friends. Victimized students were unlikely to be defended by classmates whom they disliked or who had indicated to dislike them. Finally, defending was likely to occur between students who disliked the same classmates.

2006-01-01

We examined the clinical, criminal, and sociodemographic characteristics of all white-collar crime defendants referred to the evaluation unit of a state center for forensic psychiatry. With 29,310 evaluations in a 12-year period, we found 70 defendants charged with embezzlement, 3 with health care fraud, and no other white-collar defendants (based on the eight crimes widely accepted as white-collar offenses). In a case-control study design, the 70 embezzlement cases were compared with 73 defendants charged with other forms of nonviolent theft. White-collar defendants were found to have a higher likelihood of white race (adjusted odds ratio (adj. OR) = 4.51), more years of education (adj. OR = 3471), and a lower likelihood of substance abuse (adj. OR = .28) than control defendants. Logistic regression modeling showed that the variance in the relationship between unipolar depression and white-collar crime was more economically accounted for by education, race, and substance abuse.

Pathogens require protein-folding enzymes to produce functional virulence determinants. These foldases include the Dsb family of proteins, which catalyze oxidative folding in bacteria. Bacterial disulfide catalytic processes have been well characterized in Escherichia coli K-12 and these mechanisms have been extrapolated to other organisms. However, recent research indicates that the K-12 complement of Dsb proteins is not common to all bacteria. Importantly, many pathogenic bacteria have an extended arsenal of Dsb catalysts that is linked to their virulence. To help to elucidate the process of oxidative folding in pathogens containing a wide repertoire of Dsb proteins, Salmonella enterica serovar Typhimurium has been focused on. This Gram-negative bacterium contains three DsbA proteins: SeDsbA, SeDsbL and SeSrgA. Here, the expression, purification, crystallization and preliminary diffraction analysis of these three proteins are reported. SeDsbA, SeDsbL and SeSrgA crystals diffracted to resolution limits of 1.55, 1.57 and 2.6 A and belonged to space groups P2(1), P2(1)2(1)2 and C2, respectively.

Two SODART thin foil X-ray telescopes will fly on SRG. In the focal plane of one telescope there are: HEPC/LEPC (high- and low energy imaging proportional counters), SIXA (solid state spectrometer array), and FRD (focal plane X-ray detector). In the other, there are: another HEPC/LEPC pair, SXRP (stellar X-ray polarimeter), and another FRD. Mounted alongside and co-aligned with the SODART telescopes is TAUVEX (UV telescope). An objective Bragg spectrometer is mounted in front of one of the telescopes. These instruments and their scientific goals will be described briefly. More detailed discussions will be given by the relevant PIs in the poster session.

The authors examined the rate of mental disorders in an unselected sample of homicide defendants in a U.S. jurisdiction, seeking to identify psychiatric factors associated with offense characteristics and court outcomes. Defendants charged with homicide in a U.S. urban county between 2001 and 2005 received a psychiatric evaluation after arrest. Demographic, historical, and psychiatric variables as well as offense characteristics and legal outcomes were described. Bivariate analyses examined differences by age group and by race, and logistic models examined predictors of multiple victims, firearm use, guilty plea, and guilty verdict. Fifty-eight percent of the sample had at least one axis I or II diagnosis, most often a substance use disorder (47%). Axis I or II diagnoses were more common (78%) among defendants over age 40. Although 37% of the sample had prior psychiatric treatment, only 8% of the defendants with diagnosed axis I disorders had outpatient treatment during the 3 months preceding the homicide; African Americans were less likely than non-African Americans to be in treatment. African American males were more likely to use a firearm and to have a male victim. In exploratory analyses, psychiatric factors did not predict multiple victims, firearm use in the crime, or a guilty verdict. Rates of axis I disorders were lower than reported in previous studies. Few homicide defendants were in psychiatric treatment at the time of the crime, suggesting limited opportunities for prevention by mental health providers.

Motion patterns and phase-transition of a defender-intruder problem and optimal interception strategy of the defender

NASA Astrophysics Data System (ADS)

Wang, Jiangliu; Li, Wei

2015-10-01

In this paper, we consider a defense-intrusion interaction, in which an intruder is attracted by a protected stationary target but repulsed by a defender; while the defender tries to move towards an appropriate interception position (IP) between the intruder and the target in order to intercept the intruder and expel the intruder away from the target as maximum as possible. Intuitionally, to keep the intruder further away, one may wonder that: is it a better strategy for the defender trying to approach the intruder as near as possible? Unexpectedly and interestingly enough, this is not always the case. We first introduce the flexibility for IP selection, then investigate the system dynamics and the stable motion patterns, and characterize the phase-transition surface for the motion patterns. We show that, the phase-transition surface just defines the optimal interception strategy of the defender for IP selection; and from the perspective of mobility of agents, the optimal strategy just depends on relative mobility of the two agents.

Defendant remorse, need for affect, and juror sentencing decisions.

Defendant remorse is generally accepted as a mitigating factor in capital murder sentencing in the legal system. The current study addressed whether verbal and nonverbal expressions of defendant remorse are perceived as remorseful by mock jurors. Moreover, this study investigated the associations of defendant behaviors and mock juror need for affect on sentencing decisions. Participants watched a video of a defendant depicting either high or low levels of verbal and nonverbal remorseful behavior. Results indicated that nonverbal behaviors were more important than verbal cues for perception of remorse. Incongruent verbal and nonverbal behavior, as well as mock juror willingness to approach emotional situations (i.e., high need for affect (NFA)) resulted in more lenient sentences for defendants. Implications for the remorse construct, for witness preparation, and for jury selection are discussed.

A Proposed Model for Assessing Defendant Competence to Self-Represent.

PubMed

White, Mitzi M S; Gutheil, Thomas G

2016-12-01

The increasing number of criminal defendants who are choosing to self-represent poses special challenges for legal systems with regard to the types of limits that should be placed on a defendant's basic human right to defend himself without the assistance of counsel. While courts strive to respect the dignity and autonomy of the defendant that are encompassed in this right, they also want to ensure that justice is delivered and the dignity of the courtroom is maintained. The Supreme Court of the United States, in its opinion in Indiana v. Edwards (2008), held that while the right to self-represent recognized in Faretta v. California (1975) remains, states and trial judges can place limits on a defendant's right to self-representation when a defendant lacks the mental capacities needed to prepare and conduct an adequate defense. Following the court's lead, we first examine the types and range of tasks that a defendant who chooses to self-represent must perform. Based on this analysis, we propose a five-part model that forensic practitioners can use as a conceptual framework for assessing whether a defendant has deficits that would affect his competence to perform critical self-representation tasks. The five areas that the model recommends practitioners assess are whether a defendant can engage in goal-directed behaviors, has sufficient communication skills, can engage in constructive social intercourse, can control his emotions in an adversarial arena, and has the cognitive abilities needed to argue his case adequately. It is recommended that practitioners use the model in their testimony to provide the trier of fact with a comprehensive report of the areas in which a defendant has deficits that will prevent him from protecting his interests in receiving a fair and equitable trial. © 2016 American Academy of Psychiatry and the Law.

Attacker-defender game from a network science perspective

2018-05-01

Dealing with the protection of critical infrastructures, many game-theoretic methods have been developed to study the strategic interactions between defenders and attackers. However, most game models ignore the interrelationship between different components within a certain system. In this paper, we propose a simultaneous-move attacker-defender game model, which is a two-player zero-sum static game with complete information. The strategies and payoffs of this game are defined on the basis of the topology structure of the infrastructure system, which is represented by a complex network. Due to the complexity of strategies, the attack and defense strategies are confined by two typical strategies, namely, targeted strategy and random strategy. The simulation results indicate that in a scale-free network, the attacker virtually always attacks randomly in the Nash equilibrium. With a small cost-sensitive parameter, representing the degree to which costs increase with the importance of a target, the defender protects the hub targets with large degrees preferentially. When the cost-sensitive parameter exceeds a threshold, the defender switches to protecting nodes randomly. Our work provides a new theoretical framework to analyze the confrontations between the attacker and the defender on critical infrastructures and deserves further study.

Defending Victims of Bullying in Early Adolescence: A Multilevel Analysis.

PubMed

Yun, Hye-Young; Graham, Sandra

2018-05-29

Adolescents' defending behaviors in school bullying situations is likely determined by individual characteristics, social status variables, and classroom/school contextual factors operating simultaneously in the peer ecology. However, there is little research on defending behavior that utilizes this multilevel approach. This study investigated how students' willingness to defend victims of bullying was affected by feelings of empathy, perceived popularity, and classroom-level perceived prosocial norms. Participants were 1373 adolescents (40% girls, Mage: 14 yrs) from 54 classrooms in six middle schools in South Korea. These youth reported on their feelings of empathy and how prosocial they perceived their classmates to be. Peer-ratings and peer nominations were used to estimate defending behaviors and which students were perceived as popular. Multilevel analyses showed that participants were more likely to defend victims when they had greater empathy and perceived popularity and when classroom-level prosocial norms were higher. The findings have implications for interventions to reduce school bullying and for studying defending behavior in multiple cultural contexts.

To investigate the influence of a defendant's weight on simulated jurors' perceptions of guilt. Participants were 471 lean and overweight adults (mean body mass index: 25.34±5.91) who read a vignette describing a case of check fraud while viewing one of four images of the alleged defendant (a lean male, a lean female, an obese male or an obese female). Participants rated the defendant's culpability on a 5-point Likert scale and completed measures of anti-fat attitudes. Male respondents endorsed greater overall weight bias than females (F (1470)=23.815, P<0.01, η(2)=0.048). A three-way interaction was detected between participant sex, defendant sex and defendant weight on perceptions of guilt such that when the defendant was female, male participants were significantly more likely to find her guilty if she was obese than if she was lean (guilt ratings=4.05±0.83; 3.31±1.03, respectively; F(1467)=5.935, P=0.015, R(2)=0.060). In addition, lean male participants were significantly more likely to believe that the obese female defendant met criteria for check fraud, and indicated greater belief she would be a repeat offender, compared with the lean female defendant (t(90)=2.081, P=0.040; t(90)=2.395 P=0.019, respectively). There were no differences in perceptions of guilt or responsibility between the obese male and the lean male defendants. The results of this novel study indicate that both weight and gender of a defendant may affect juror perceptions of guilt and responsibility.

The psychology of defendant plea decision making.

Every day, thousands of defendants, prosecutors, and defense attorneys must make guilty plea decisions, such as whether to accept a plea offer or proceed to trial. Most defendants opt to plead guilty; approximately 95% of state and federal convictions result from guilty pleas. In light of a newly emerging body of research and recent Supreme Court decisions on guilty pleas, this article asks and answers 2 questions: First, who pleads guilty and why? We describe the characteristics of those who are more or less likely to plead guilty, and examine the reasons why individuals plead guilty instead of proceeding to trial, exploring the cognitive, social influence, and developmental factors that underlie decision making. Second, are defendants' plea decisions valid, in that the decisions are made knowingly, intelligently, voluntarily, and with a factual basis of guilt? That is, do defendants who plead guilty understand and appreciate the conditions and consequences of their pleas, as required by law? Are innocent people induced to plead guilty to crimes they did not commit? We conclude with suggestions to move the field of plea research forward.

analysis was done as a function of cure time and temperatures. Adhesion bond strength was tested at various temperatures with lap shear samples using Hiperco 50 substrate to ensure that the proper adhesive is being used. To try and solve the problem of bondline thickness, micro glass beads of 0.0017" in diameter were investigated to see if any other physical properties of the epoxy were affected. Efforts will be made to develop a standard, optimized, fabrication process/procedure of sub-scale magnet-stator assemblies for various adhesive performance evaluation studies under simulated generator conditions. Also, accelerated aging testing will be done in a pressurized canister with stator assembly samples for three years to verify if any degassing or thermal degradation of the epoxy occurs. The necessity of verifying the correct epoxy adhesive system for the stator magnet in the SRG is crucial because failure of the stator assembly would jeopardize the electrical system, and thereby the entire mission itself. My work involves specimen fabrications, testing, and data analyses of the epoxy adhesive system for the stator magnet in the SRG is crucial because failure of the stator assembly would jeopardize the electrical system, and thereby the entire mission itself.

Defending sleepwalkers with science and an illustrative case.

Cartwright, Rosalind D; Guilleminault, Christian

2013-07-15

To test whether laboratory-based research differentiating sleepwalkers (SW) from controls (C) can be applied in an uncontrolled forensic case as evidence the alleged crime was committed during an arousal from sleep in which the mind is not fully conscious due to a SW disorder. A PSG study recorded 8 months after the defendant was charged was analyzed independently by spectral analysis. Slow wave activity (SWA) and cyclic alternating pattern (CAP) rates were computed. Clinical interviews and police records were reviewed for data re: the defendant's sleep prior to the event and use of drugs, alcohol, and stimulants. The SWA distribution was abnormally low and flat, significantly lower than published controls; in the first NREM cycle, CAP rate 55 was above normal. Two weeks of prior sleep deprivation was confirmed from interviews and defendant's observed daytime sleepiness. Caffeine intake the day before the event was calculated at 826 mg over 14 hours. Snoring and a mild breathing disorder were present in the PSG. Testimony based on spectral analysis of PSG recorded following an alleged criminal event supported a SW explanation for the non-rational behaviors charged. The defendant was acquitted of all charges and has been successfully treated.

Factors affecting jail detention of defendants adjudicated incompetent to proceed.

2010-01-01

The movement of defendants through the legal process who have been adjudicated incompetent to proceed is little studied, yet it is important. The purpose of this study was to provide empirical data regarding factors that affected the amount of time defendants adjudicated incompetent to proceed and ordered to undergo hospitalization remained in jail while awaiting transfer to a state hospital. Statewide data collected in Florida between July 2005 and June 2008 were used to determine the lengths of time incompetent defendants spent at certain stages in the legal process. The addition of forensic bed capacity following media attention and litigation resulted in a significant decrease in the amount of time defendants adjudicated incompetent to proceed waited in jail for transfer to a state hospital for treatment. The amount of time it took for completed commitment orders to be submitted to the state mental health authority by the Clerks of Court of each county accounted for a meaningful portion of days defendants spent in jail awaiting transfer to a state hospital, with considerable variation across counties with respect to waiting times. These findings reflect how various stakeholders can affect the amount of time defendants spend in jail while awaiting hospitalization. These issues are discussed in the context of controversy related to Florida's forensic mental health system, as well as issues related to the political process and funding of the state's mental health authority.

Deterrence and Risk Preferences in Sequential Attacker-Defender Games with Continuous Efforts.

PubMed

Payyappalli, Vineet M; Zhuang, Jun; Jose, Victor Richmond R

2017-11-01

Most attacker-defender games consider players as risk neutral, whereas in reality attackers and defenders may be risk seeking or risk averse. This article studies the impact of players' risk preferences on their equilibrium behavior and its effect on the notion of deterrence. In particular, we study the effects of risk preferences in a single-period, sequential game where a defender has a continuous range of investment levels that could be strategically chosen to potentially deter an attack. This article presents analytic results related to the effect of attacker and defender risk preferences on the optimal defense effort level and their impact on the deterrence level. Numerical illustrations and some discussion of the effect of risk preferences on deterrence and the utility of using such a model are provided, as well as sensitivity analysis of continuous attack investment levels and uncertainty in the defender's beliefs about the attacker's risk preference. A key contribution of this article is the identification of specific scenarios in which the defender using a model that takes into account risk preferences would be better off than a defender using a traditional risk-neutral model. This study provides insights that could be used by policy analysts and decisionmakers involved in investment decisions in security and safety. © 2017 Society for Risk Analysis.

Modeling Resources Allocation in Attacker-Defender Games with "Warm Up" CSF.

PubMed

Guan, Peiqiu; Zhuang, Jun

2016-04-01

Like many other engineering investments, the attacker's and defender's investments may have limited impact without initial capital to "warm up" the systems. This article studies such "warm up" effects on both the attack and defense equilibrium strategies in a sequential-move game model by developing a class of novel and more realistic contest success functions. We first solve a single-target attacker-defender game analytically and provide numerical solutions to a multiple-target case. We compare the results of the models with and without consideration of the investment "warm up" effects, and find that the defender would suffer higher expected damage, and either underestimate the attacker effort or waste defense investment if the defender falsely believes that no investment "warm up" effects exist. We illustrate the model results with real data, and compare the results of the models with and without consideration of the correlation between the "warm up" threshold and the investment effectiveness. Interestingly, we find that the defender is suggested to give up defending all the targets when the attack or the defense "warm up" thresholds are sufficiently high. This article provides new insights and suggestions on policy implications for homeland security resource allocation. © 2015 Society for Risk Analysis.

Defending legitimate epidemiologic research: combating Lysenko pseudoscience.

Enstrom, James E

2007-10-10

This analysis presents a detailed defense of my epidemiologic research in the May 17, 2003 British Medical Journal that found no significant relationship between environmental tobacco smoke (ETS) and tobacco-related mortality. In order to defend the honesty and scientific integrity of my research, I have identified and addressed in a detailed manner several unethical and erroneous attacks on this research. Specifically, I have demonstrated that this research is not "fatally flawed," that I have not made "inappropriate use" of the underlying database, and that my findings agree with other United States results on this relationship. My research suggests, contrary to popular claims, that there is not a causal relationship between ETS and mortality in the U.S. responsible for 50,000 excess annual deaths, but rather there is a weak and inconsistent relationship. The popular claims tend to damage the credibility of epidemiology. In addition, I address the omission of my research from the 2006 Surgeon General's Report on Involuntary Smoking and the inclusion of it in a massive U.S. Department of Justice racketeering lawsuit. I refute erroneous statements made by powerful U.S. epidemiologists and activists about me and my research and I defend the funding used to conduct this research. Finally, I compare many aspect of ETS epidemiology in the U.S. with pseudoscience in the Soviet Union during the period of Trofim Denisovich Lysenko. Overall, this paper is intended to defend legitimate research against illegitimate criticism by those who have attempted to suppress and discredit it because it does not support their ideological and political agendas. Hopefully, this defense will help other scientists defend their legitimate research and combat "Lysenko pseudoscience."

I refute erroneous statements made by powerful U.S. epidemiologists and activists about me and my research and I defend the funding used to conduct this research. Finally, I compare many aspect of ETS epidemiology in the U.S. with pseudoscience in the Soviet Union during the period of Trofim Denisovich Lysenko. Overall, this paper is intended to defend legitimate research against illegitimate criticism by those who have attempted to suppress and discredit it because it does not support their ideological and political agendas. Hopefully, this defense will help other scientists defend their legitimate research and combat "Lysenko pseudoscience." PMID:17927827

Effects of defendant and victim race on perceptions of juvenile sex offenders.

2009-01-01

We investigated effects of defendant race, victim race, and juror gender on public perceptions of a juvenile sex offense. We predicted that participants, particularly men, would support registering a juvenile defendant as a sex offender more when he was Black than White and that participants, particularly women, would support registering the defendant more when the female crime victim was portrayed as White than as Black. We also expected that support for registration would be higher when the defendant and victim were different races than when they were the same race. As expected, women (but not men) recommended registration more when the victim was White than Black. Further, participants supported registration more when the defendant and the victim were different races than when they were the same race. These effects were mediated by retributive goals to punish the offender-not by utilitarian goals to protect society. Explanations and implications are discussed.

Defender-Attacker Decision Tree Analysis to Combat Terrorism.

PubMed

Garcia, Ryan J B; von Winterfeldt, Detlof

2016-12-01

We propose a methodology, called defender-attacker decision tree analysis, to evaluate defensive actions against terrorist attacks in a dynamic and hostile environment. Like most game-theoretic formulations of this problem, we assume that the defenders act rationally by maximizing their expected utility or minimizing their expected costs. However, we do not assume that attackers maximize their expected utilities. Instead, we encode the defender's limited knowledge about the attacker's motivations and capabilities as a conditional probability distribution over the attacker's decisions. We apply this methodology to the problem of defending against possible terrorist attacks on commercial airplanes, using one of three weapons: infrared-guided MANPADS (man-portable air defense systems), laser-guided MANPADS, or visually targeted RPGs (rocket propelled grenades). We also evaluate three countermeasures against these weapons: DIRCMs (directional infrared countermeasures), perimeter control around the airport, and hardening airplanes. The model includes deterrence effects, the effectiveness of the countermeasures, and the substitution of weapons and targets once a specific countermeasure is selected. It also includes a second stage of defensive decisions after an attack occurs. Key findings are: (1) due to the high cost of the countermeasures, not implementing countermeasures is the preferred defensive alternative for a large range of parameters; (2) if the probability of an attack and the associated consequences are large, a combination of DIRCMs and ground perimeter control are preferred over any single countermeasure. © 2016 Society for Risk Analysis.

Possibility of death sentence has divergent effect on verdicts for Black and White defendants.

PubMed

Glaser, Jack; Martin, Karin D; Kahn, Kimberly B

2015-12-01

When anticipating the imposition of the death penalty, jurors may be less inclined to convict defendants. On the other hand, minority defendants have been shown to be treated more punitively, particularly in capital cases. Given that the influence of anticipated sentence severity on verdicts may vary as a function of defendant race, the goal of this study was to test the independent and interactive effects of these factors. We conducted a survey-embedded experiment with a nationally representative sample to examine the effect on verdicts of sentence severity as a function of defendant race, presenting respondents with a triple murder trial summary that manipulated the maximum penalty (death vs. life without parole) and the race of the defendant. Respondents who were told life-without-parole was the maximum sentence were not significantly more likely to convict Black (67.7%) than White (66.7%) defendants. However, when death was the maximum sentence, respondents presented with Black defendants were significantly more likely to convict (80.0%) than were those with White defendants (55.1%). The results indicate that the death penalty may be a cause of racial disparities in criminal justice, and implicate threats to civil rights and to effective criminal justice.

Jurors' locus of control and defendants' attractiveness in death penalty sentencing.

PubMed

Beckham, Crystal M; Spray, Beverly J; Pietz, Christina A

2007-06-01

The authors examined the relationship between jurors' locus of control and defendants' attractiveness in death penalty sentencing. Ninety-eight participants voluntarily served as mock jurors. The authors administered J. B. Rotter's (1966) Internal-External Locus of Control Scale to participants and then randomly assigned them to a group with either an attractive or an unattractive defendant (represented by photographs). Participants read a murder vignette and selected a punishment--either a lifetime jail sentence or the death penalty-for the defendant. Results indicated that neither jurors' locus of control nor defendants' attractiveness influenced sentencing. However, jurors' age and gender significantly influenced sentencing. Men, with the exception of the youngest men, were more likely than women to choose the death penalty. Additionally, young women were more likely than older women to select the death penalty. The authors discuss the implications of these results for the study of jury behavior and bias.

The exploitation of an ant-defended host plant by a shelter-building herbivore.

PubMed

Eubanks, Micky D; Nesci, Kimberly A; Petersen, Mette K; Liu, Zhiwei; Sanchez, Horacio Bonfil

1997-02-01

Larvae of a Polyhymno species (Lepidoptera: Gelechiidae) feed on the ant-defended acacia, Acacia cornigera, in the tropical lowlands of Veracruz, Mexico. Polyhymno larvae construct sealed shelters by silking together the pinna or pinnules of acacia leaves. Although larval density and larval survival are higher on acacias not occupied by ants, shelters serve as a partial refuge from the ant Pseudomyrmex ferruginea (Hymenoptera: Formicidae), which defends A. cornigera plants; thus, shelters provide Polyhymno larvae access to an ant-defended host plant. P. ferruginea ants act as the primary antiherbivore defense of A. cornigera plants, which lack the chemical and mechanical defenses of non-ant-defended acacias. Thus, defeating the ant defense of A. cornigera provides Polyhymno larvae access to an otherwise poorly defended host plant. Damage caused by Polyhymno larval feeding reaches levels which can kill A. cornigera plants.

Colozza, Anthony J.; Cataldo, Robert L.

2015-01-01

This study looks at the applicability of utilizing the Segmented Thermoelectric Modular Radioisotope Thermoelectric Generator (STEM-RTG) or a high-power radioisotope generator to replace the Advanced Stirling Radioisotope Generator (ASRG), which had been identified as the baseline power system for a number of planetary exploration mission studies. Nine different Discovery-Class missions were examined to determine the applicability of either the STEM-RTG or the high-power SRG power systems in replacing the ASRG. The nine missions covered exploration across the solar system and included orbiting spacecraft, landers and rovers. Based on the evaluation a ranking of the applicability of each alternate power system to the proposed missions was made.

We previously estimated the timing when ball game defenders detect relevant information through visual input for reacting to an attacker's running direction after a cutting manoeuvre, called cue timing. The purpose of this study was to investigate what specific information is relevant for defenders, and how defenders process this information to decide on their opponents' running direction. In this study, we hypothesised that defenders extract information regarding the position and velocity of the attackers' centre of mass (CoM) and the contact foot. We used a model which simulates the future trajectory of the opponent's CoM based upon an inverted pendulum movement. The hypothesis was tested by comparing observed defender's cue timing, model-estimated cue timing using the inverted pendulum model (IPM cue timing) and cue timing using only the current CoM position (CoM cue timing). The IPM cue timing was defined as the time when the simulated pendulum falls leftward or rightward given the initial values for position and velocity of the CoM and the contact foot at the time. The model-estimated IPM cue timing and the empirically observed defender's cue timing were comparable in median value and were significantly correlated, whereas the CoM cue timing was significantly more delayed than the IPM and the defender's cue timings. Based on these results, we discuss the possibility that defenders may be able to anticipate the future direction of an attacker by forwardly simulating inverted pendulum movement.

Competency to stand trial and defendants who lack insight into their mental illness.

PubMed

Reisner, Andrew D; Piel, Jennifer; Makey, Miller

2013-01-01

Forensic evaluators often assess patients who lack insight into their mental illnesses. This lack of insight can have a significant impact on the defendant's ability to make legal strategy decisions that rely on their acceptance of their mental illness. In this article, the relationship between refusing an insanity plea and competency to stand trial will be explored in the context of defendants who lack insight into their mental illness. The authors argue that an adequate competency assessment should take into account the defendant's ability to consider his available pleas rationally. Such evaluations may have the effect of negating the necessity of a Frendak inquiry in those jurisdictions that can impose the insanity defense on defendants.

Main and moderated effects of moral cognition and status on bullying and defending.

PubMed

Caravita, Simona C S; Gini, Gianluca; Pozzoli, Tiziana

2012-01-01

This study analyzed the relations of two dimensions of moral cognition (i.e., acceptance of moral transgression and moral disengagement) and two forms of status in the peer group (i.e., social preference and perceived popularity) with bullying and defending among 235 primary-school children and 305 middle-school early adolescents. Social status was tested as a moderator of the associations between moral cognition and bullying and defending. Participants completed self-reports assessing the two dimensions of moral cognition and peer nominations for status, bullying, and defending. Both acceptance of moral transgression and moral disengagement were associated to bullying among early adolescents only, whereas in childhood moral disengagement was linked to defending among girls. Social status moderated the associations between morality dimensions and bullying and defending. The moderating effects of status were discussed considering status as a magnifying lens for the relations between individual characteristics and social behavior. The results were also discussed with reference to age and gender differences in the associations. © 2012 Wiley Periodicals, Inc.

Does Ability to Defend Moderate the Association between Exposure to Bullying and Symptoms of Anxiety?

PubMed Central

Nielsen, Morten Birkeland; Gjerstad, Johannes; Jacobsen, Daniel Pitz; Einarsen, Ståle Valvatne

2017-01-01

In the context of workplace bullying, the ability to defend refers to whether or not a target feels able to deal with those negative behaviors that typically constitute bullying. The aim of this study was to determine whether the perceived ability to defend oneself moderates the association between exposure to bullying behaviors at work and symptoms of anxiety as predicted by the definition of workplace bullying. It was hypothesized that exposure to bullying behaviors would be more strongly related to symptoms of anxiety among targets feeling unable to defend oneself than among targets who do feel that they are able to defend themselves in the actual situation. This survey study was based on a probability sample of 1,608 Norwegian employees (response rate 32%). Only respondents exposed to at least one bullying behavior were included (N = 739). In contrast to hypothesis, the findings showed that ability to defend only had a protective effect on the relationship between exposure to bullying behaviors and anxiety in cases of low exposure. In cases of high exposure, there was a stronger increase in anxiety among employees able to defend themselves than among those who generally felt unable to defend. Hence, the ability to defend against exposure to bullying behaviors does not seem to protect high-exposed targets against symptoms of anxiety. Organization should therefore intervene against bullying in early stages rather than relying on the individual resilience of those exposed. PMID:29163321

Rate of false conviction of criminal defendants who are sentenced to death

PubMed Central

Gross, Samuel R.; O’Brien, Barbara; Hu, Chen; Kennedy, Edward H.

2014-01-01

The rate of erroneous conviction of innocent criminal defendants is often described as not merely unknown but unknowable. There is no systematic method to determine the accuracy of a criminal conviction; if there were, these errors would not occur in the first place. As a result, very few false convictions are ever discovered, and those that are discovered are not representative of the group as a whole. In the United States, however, a high proportion of false convictions that do come to light and produce exonerations are concentrated among the tiny minority of cases in which defendants are sentenced to death. This makes it possible to use data on death row exonerations to estimate the overall rate of false conviction among death sentences. The high rate of exoneration among death-sentenced defendants appears to be driven by the threat of execution, but most death-sentenced defendants are removed from death row and resentenced to life imprisonment, after which the likelihood of exoneration drops sharply. We use survival analysis to model this effect, and estimate that if all death-sentenced defendants remained under sentence of death indefinitely, at least 4.1% would be exonerated. We conclude that this is a conservative estimate of the proportion of false conviction among death sentences in the United States. PMID:24778209

The verdict on jury trials for juveniles: the effects of defendant's age on trial outcomes.

PubMed

Warling, Diane; Peterson-Badali, Michele

2003-01-01

With the progression to more adult-like policies and procedures for youth in the justice system, the right to a jury trial has been extended to young offenders. These youth would not be tried by a jury of their peers, however, but by a jury of adults. The concern is that adult jurors may hold negative attitudes about youth that might influence their decision making in a case involving a young defendant. Two studies examined whether and under what conditions defendant's age affects jurors' decisions about the guilt and sentencing of an accused. In study 1, data were gathered from two samples of jury eligible adults: one university sample and one public sample. Mock jurors read written transcripts of a trial involving a defendant who was presented as either 13, 17, or 25 years of age. Results indicated that the defendant's age had no effect on mock jurors' verdict or their ratings of defendant guilt. However, younger defendants were granted shorter sentences than the adult defendants. In study 2, mock jurors read the same trial presented in study 1 but were asked to deliberate about the case and render group verdicts. These group verdicts did not differ significantly by defendant's age. Age-related themes that emerged from group deliberations were identified, and results indicated that age tended to be used as a mitigating factor in favor of youth rather than against them. These findings are discussed in terms of their implications for youth justice policy and practice. Copyright 2003 John Wiley & Sons, Ltd.

Security under Uncertainty: Adaptive Attackers Are More Challenging to Human Defenders than Random Attackers

PubMed Central

Moisan, Frédéric; Gonzalez, Cleotilde

2017-01-01

Game Theory is a common approach used to understand attacker and defender motives, strategies, and allocation of limited security resources. For example, many defense algorithms are based on game-theoretic solutions that conclude that randomization of defense actions assures unpredictability, creating difficulties for a human attacker. However, many game-theoretic solutions often rely on idealized assumptions of decision making that underplay the role of human cognition and information uncertainty. The consequence is that we know little about how effective these algorithms are against human players. Using a simplified security game, we study the type of attack strategy and the uncertainty about an attacker's strategy in a laboratory experiment where participants play the role of defenders against a simulated attacker. Our goal is to compare a human defender's behavior in three levels of uncertainty (Information Level: Certain, Risky, Uncertain) and three types of attacker's strategy (Attacker's strategy: Minimax, Random, Adaptive) in a between-subjects experimental design. Best defense performance is achieved when defenders play against a minimax and a random attack strategy compared to an adaptive strategy. Furthermore, when payoffs are certain, defenders are as efficient against random attack strategy as they are against an adaptive strategy, but when payoffs are uncertain, defenders have most difficulties defending against an adaptive attacker compared to a random attacker. We conclude that given conditions of uncertainty in many security problems, defense algorithms would be more efficient if they are adaptive to the attacker actions, taking advantage of the attacker's human inefficiencies.

Friendship selection and influence in bullying and defending: effects of moral disengagement.

PubMed

Sijtsema, Jelle J; Rambaran, J Ashwin; Caravita, Simona C S; Gini, Gianluca

2014-08-01

The current study examined the development of bullying and defending over a 1-year period as related to friends' influence and individual and friends' moral disengagement (i.e., self-justification mechanisms that allow one to avoid moral self-censure of transgressive actions) in children and young adolescents. Via longitudinal social network analysis (RSiena), it was tested whether similarity between friends in bullying and defending developed over time due to friends' influence, while controlling for friendship selection processes, and whether there were differences in these processes between children (age 9-10 years; n = 133; 42.9% girls) and young adolescents (age 11-14 years; n = 236; 40.6% girls). Results showed that individuals selected peers as friends who were similar in bullying and became more similar to friends in bullying over time, but only in early adolescence. Moreover, there was marginal support that friends' influence was stronger in young adolescents with higher moral disengagement. In early adolescence, bullying was also indirectly influenced through friends' moral disengagement, with different effects for boys and girls. With regard to defending, young adolescents maintained friendships with peers who were similar in defending, and became more similar to friends in terms of defending over time. These findings suggest important differences between late childhood and early adolescence in socialization processes and indicate that in early adolescence, friends' influence on the development of bullying is partially affected by moral disengagement.

2001-10-01

The authors examined the effects of interactions (a) between defendant attractiveness and juror gender and (b) between defendant race and juror race on judgment and sentencing among 207 Black, Hispanic, and White participants in the United States. After reading a vehicular-homicide vignette in which the defendant's attractiveness and race varied, the participants rated guilt and recommended sentences. The women treated the unattractive female defendant more harshly than they treated the attractive female defendant; the men showed an opposite tendency. The Black participants showed greater leniency when the defendant was described as Black rather than White. The Hispanic participants showed an opposite trend, and the White participants showed no race-based leniency. The findings on racial effects were consistent (a) with in-group favorability bias among the Black participants and (b) with attribution effects unrelated to race among the White participants.

Efficacy of legal judgments for defendants with traumatic brain injury.

PubMed

St Pierre, Maria E; Parente, Rick

2016-06-23

Literature has compared the frequency of aggressive behaviors of the TBI population and the non-TBI population, suggesting that the TBI population is predisposed to aggressive tendencies because the injury enables impulsivity, loss of self-control, and the inability to modify behaviors. These behavior changes have consequently, been found to lead to criminal involvement. In fact, the majority of the prison population has sustained at least one TBI in their lifetime compared to the prevalence of brain injuries in the general population. However, there is little research investigating the perceptions of criminality and guilt of these individuals. Two experiments were conducted that investigated the perceptions of morality, level of guilt, and appropriate sentencing of crimes committed by defendants with different severities of TBI (i.e., mild, severe, and no TBI). Participants were asked to read scenarios about crimes being committed by the defendant. Experiment 1 used a 1-between (crime), 1-within (TBI) mixed design ANOVA testing three dependent variables (morality, guilt, and sentencing). Using a more in vivo jury approach, Experiment 2 used a 3 (TBI)×2 (crime) independent groups factorial design testing the three dependent measures. Overall, defendants with TBI were found less guilty of their crime, perceived as behaving morally to the crime, and receiving a milder punishment relative to the no-TBI defendants. In the courtroom, the defense attorney should educate the judge and/or the jury on the effects brain injuries have on the cognition, behavior, and emotions of an individual. Thus, this education will ensure the best verdict is being reached.

Students should be encouraged to help prevent or stop bullying. However, defending victims of bullying can impact on mental health. It is not only bystanders who may defend victims, but bullies, victims and bully-victims can also have defending behaviors. Nevertheless, most studies of defending behaviors have been limited to an examination of the reactions of bystanders or those not involved in bullying and have ignored the other players. The aim of this study is to investigate the associations between defending behaviors and mental health among bullies, victims, bully-victims and bystanders. Associations among defending behaviors, mental health (including depressive symptoms and social anxiety), and bullying experiences were cross-sectionally examined in 3441 students (13-15 years old.) from 20 randomly selected junior high schools in Taiwan using a self-report questionnaire. SAS 9.3 Survey Analysis procedures were used to conduct descriptive analysis and multiple regression models. Defending behaviors were associated with bullying roles and were higher in victims than in bullies or bystanders. Defending behaviors were positively associated with social anxiety and depressive symptoms. After stratifying by bullying roles, defending behaviors were positively associated with social anxiety in bystanders, and were positively associated with depressive symptoms in victims and bystanders. However, defending behaviors were not significantly associated with mental health indicators in bullies. The associations between defending behaviors and mental health varied according to bullying roles. The results suggest that bystanders and victims experience more mental health effects than bullies. Intervention programs aimed at preventing bullying should focus on strategies that minimize social anxiety and depression in victims and bystanders, and urge students to help vulnerable peers during bullying events.

Active Hearing Defenders are established hearing protectors with in-built electro-acoustics that shut-off ambient noise while allowing effective communication between users. A blinded, self-controlled trial was conducted among naval servicemen to compare the effectiveness of two types of active hearing defenders (Howard-Leight Thunder TM and COM-55) in relation to passive hearing defenders in an operational environment. Subjects felt that the active hearing defenders were more comfortable, durable, and that the active hearing defenders helped them work better. When subjects were tested with a speech discrimination battery (Central Institute of the Deaf, Spondee Word lists), there was a significant difference (p value of 0.04, using the Kruskall-Wallis ANOVA test) between the two active and the passive defenders. However, no significant difference was found between the two types of active hearing defenders. Active hearing defenders are an acceptable and efficacious means of hearing protection in noisy environments.

2015-04-01

This study examined the continuous interpersonal interactions of performers in dyadic systems in team sports, as a function of changing information constraints. As a task vehicle, we investigated how attackers attained success in 1v1 sub-phases of basketball by exploring angular relations with immediate opponents and the basket. We hypothesized that angular relations would convey information for the attackers to dribble past defenders. Four basketball players performed as an attacker and defender in 1v1 sub-phases of basketball, in which the co-positioning and orientation of participants relative to the basket was manipulated. After video recording performance behaviors, we digitized participant movement displacement trajectories and categorized trials as successful or unsuccessful (from the attackers' viewpoint). Results revealed that, to successfully dribble past a defender, attackers tended to explore the left hand side of the space by defenders by increasing their angular velocity and decreasing their angular variability, especially in the center of the court. Interpersonal interactions and goal-achievement in attacker-defender dyads appear to have been constrained by the angular relations sustained between participants relative to the scoring target. Results revealed the functionality of exploratory behaviors of participants attempting re-align spatial relations with an opponent in 1v1 sub-phases of team games. Copyright © 2015 Elsevier B.V.

Bullying and defending behavior: The role of explicit and implicit moral cognition.

PubMed

Pozzoli, Tiziana; Gini, Gianluca; Thornberg, Robert

2016-12-01

Research on bullying has highlighted the role of morality in explaining the different behavior of students during bullying episodes. However, the research has been limited to the analysis of explicit measures of moral characteristics and moral reasoning, whereas implicit measures have yet to be fully considered. To overcome this limitation, this study investigated the association between bullying and defending, on one hand, and both explicit (moral disengagement, self-importance of moral values) and implicit (immediate affect toward moral stimuli [IAMS]) moral components, on the other hand. Young adolescents (N=279, mean age=11years, 9months, 44.4% girls) completed a series of self-report scales and individually performed a computer task investigating the IAMS. Two hierarchical regressions (bootstrapping method) were performed. Results showed that moral disengagement was associated with bullying and defending behavior at high levels of IAMS, however not when IAMS was low. In contrast, self-importance of moral values was not significantly associated to the two behaviors when IAMS was high whereas both associations were significant at low levels of IAMS. These results significantly expand previous knowledge about the role of morality in bullying and defending behavior. In particular, they highlight the role of the interaction between explicit and implicit moral dimensions in predicting bullying and defending behaviors.

Effect of criminal defendant's history of childhood sexual abuse and personality disorder diagnosis on juror decision making.

PubMed

Butler, Ebony; Jacquin, Kristine

2014-08-01

This study investigated whether a defendant's history of childhood sexual abuse (CSA) and/or personality disorder (PD) diagnosis affected juror decision making in a child sexual abuse trial. The PDs in the study were borderline PD and antisocial PD. Participants were 385 college students, 121 men and 264 women, who read a summary of a mock criminal trial and then made various juror decisions. Trial summaries were prepared by the principal investigator and were all uniform in content, length and detail. For the trial, both the defendant's gender and victim's gender were specified. The defendant was male, and the alleged victim was female. When the verdict was assessed, the results yielded that when the defendant's CSA history was presented, juror guilt ratings were higher than when there was no history of CSA. Similarly, when the defendant had a PD diagnosis, there were higher guilt ratings than when there was no PD diagnosis. CSA history and PD diagnosis were significant predictors of guilt ratings, suggesting that jurors perceive defendants more negatively if they have either been sexually abused as a child or have borderline or antisocial PD.

Juror Decision-making in Death Penalty Sentencing when Presented with Defendant's History of Child Abuse or Neglect.

PubMed

Bell Holleran, Lisa L; Vaughan, Tyler J; Vandiver, Donna M

2016-11-01

Previous studies have found aggravating, mitigating, and null effects of defendant histories of abuse and neglect on punishment preferences in capital sentencing. Perceiving these defendants as more dangerous, jurors may be more likely to favor the death penalty when such evidence is presented. This is counter to the intuition that abuse or neglect reduces culpability, and therefore mitigates the severity of punishment. We investigated the effect of defendant childhood physical abuse, sexual abuse, or neglect on the probability of a prospective juror preferring the death penalty in an between-subject experimental design. Using vignettes and two large samples (students and jurors), defendant histories were found to mitigate the probability that the hypothetical defendant received the death penalty, with sexual abuse having the most salient effect. Further, the effects were conditioned by preference for the death penalty - larger mitigating effects were observed among individuals who favor the death penalty. These findings suggest that initial judgments of abuse and neglect are related to juror leniency, and further research on the interaction of jury instructions and defendant histories is needed.

Defendant mental illness and juror decision-making: A comparison of sample types.

PubMed

Mossière, Annik; Maeder, Evelyn M

2015-01-01

Two studies were conducted with separate student and community samples to explore the effect of sample types and the influence of defendant mental illness on juror decision-making. Following the completion of a pre-trial questionnaire in which jurors' attitudes towards mental illness were assessed, participants were provided with a robbery trial transcript, wherein the mental illness of the defendant was manipulated. Participants then answered a questionnaire to assess their knowledge of the scenario, their verdict, verdict confidence, and sentencing decision. Limited relationships were found between the variables in both Study 1 and Study 2. Neither attitude ratings nor mental illness type had a significant effect on juror decisions. Samples differed in terms of the paths through which juror decisions were achieved. Findings suggest that sample type may be particularly relevant for this topic of study, and that future research is required on legal proceedings for cases involving a defendant with a mental illness.

Charitable collaborations in Bronzeville, 1928-1944: the "Chicago Defender" and the Regal Theater.

PubMed

Semmes, Clovis E

2011-01-01

In the twentieth century, race-based residential and commercial segregation that supported racial oppression and inequality became an elemental characteristic of urban black communities. Conflict-ridden, black-white relationships were common. However, the Chicago Defender Charities, Inc., the entity that sponsors the largest African American parade in the country and that emerged in 1947, embodied a tradition of charitable giving, self-help, and community service initiated in 1921 by Chicago Defender newspaper founder and editor, Robert S. Abbott. The foundation of this charitable tradition matured as a result of an early and sustained collaboration between Chicago’s white-owned Regal Theater and the black-owned Chicago Defender newspaper. Thus, in segregated African American communities, black and white commercial institutions, under certain conditions, were able to find important points of collaboration to uplift the African American communities of which they were a part.

Talking about a black man: the influence of defendant and character witness race on jurors' use of character evidence.

PubMed

Maeder, Evelyn M; Hunt, Jennifer S

2011-01-01

To determine whether anti-Black bias influences mock jurors' use of character evidence (i.e., information about a defendant's personality), this study manipulated the race (Black, White) of the defendant and character witness and the type of character evidence presented in a fictitious criminal trial. Two hundred six predominantly White participants read a trial transcript, then made verdicts and trial judgments. Results confirm previous findings that positive character evidence has a limited impact on jurors' judgments, but negative character evidence is misused to evaluate the defendant's guilt. However, participants were more influenced by character evidence that was inconsistent with racial stereotypes. Specifically, positive character evidence had a stronger effect for Black defendants, whereas negative rebuttal evidence had a stronger influence for White defendants. The race of the character witness did not affect judgments. Thus, defendant race may provide a framework that influences how mock jurors process character evidence.

A. Lincoln, esquire defends the murderer of a physician.

PubMed

Spiegel, Allen D; Kavaler, Florence

2005-08-01

After only about a year of law practice, Abraham Lincoln participated in his first murder trial. Dr. Jacob M. Early was shot and killed in a bitter political imbroglio. Lincoln joined a defense team of highly accomplished litigators. Despite his having the least legal experience, he was selected to give the defense summation. In his argument, he spoke to the jury in a conversational tone making his point that Dr. Early had a deadly weapon in his hands, namely an upraised wooden chair, when he was shot. His self-defense plea indicated that Henry B. Truett, the defendant, truly believed that he was in danger of being crushed by the upraised chair. Interestingly, Lincoln knew both the defendant and the murdered physician. He handled litigation for the former and served in the Black Hawk War under the command of the latter. Furthermore Lincoln knew at least five of the jurors.

Classroom relationship qualities and social-cognitive correlates of defending and passive bystanding in school bullying in Sweden: A multilevel analysis.

PubMed

Thornberg, Robert; Wänström, Linda; Hong, Jun Sung; Espelage, Dorothy L

2017-08-01

Using the social-ecological and social cognitive theories as integrated guiding frameworks, the present study examined whether moral disengagement and defender self-efficacy at the individual level, and moral disengagement, quality of teacher-student relationships and quality of student-student relationships at the classroom level were associated with passive bystanding and defending in bullying situations. Participants were 900 Swedish students from 43 classrooms, ranging in age from 9 to 13years. Multilevel regression analyses revealed that passive reactions by bystanders were associated with greater moral disengagement and less defender self-efficacy. Defending, in turn, was associated with less moral disengagement and greater defender self-efficacy and classroom student-student relationship quality. Furthermore, students who scored high in moral disengagement were even less prone to defend victims when the classroom student-student relationship quality was low, but more prone to act as defenders when the classroom student-student relationship quality was high. In addition, the negative association between defender self-efficacy and passive bystanding was stronger both in classrooms with higher student-student relationship quality and in those with lower class moral disengagement. Implications for prevention are discussed. Copyright © 2017 Society for the Study of School Psychology. All rights reserved.

Will my malpractice case be settled? The physician-defendant's voice in the decision.

PubMed

Archambault, William H

2007-05-01

Malpractice claims are an unavoidable part of the practice of clinical medicine. Physicians purchase professional liability insurance to protect themselves from financial and other adverse consequences of such claims. Insurance policies require the insurer to hire attorneys to represent, defend and advise physicians who are named as defendants in medical malpractice lawsuits. Insurance policies require insurers to pay the costs associated with defending the lawsuit and paying, within policy limits, any damages for which a physician is determined to be liable. The relationship between insurer, defense counsel and physician can be complicated by divergent interests, concerns and priorities. It is important for physicians to be knowledgeable consumers when they are in the market for malpractice coverage. Familiarity with types of coverage, controls placed on defense costs and policy terms that determine decision-making authority on settlement issues are essential to making an informed purchase of insurance coverage.

Abuse Is Abuse: The Influence of Type of Abuse, Victim Age, and Defendant Age on Juror Decision Making.

PubMed

Sheahan, Chelsea L; Pica, Emily; Pozzulo, Joanna D

2017-09-01

The purpose of the current study was to examine the role of victim age, defendant age, and type of abuse on mock juror decision making. Mock jurors ( N = 556) read a trial transcript in which a soccer coach was accused of sexual abuse or physical abuse against a player. The victim's age (child, adolescent, or young adult), the defendant's age (young, middle age, or older adult), and the type of abuse (sexual or physical) were varied. Mock jurors provided a dichotomous and continuous verdict and rated their perceptions of the victim and the defendant. Although no differences on mock jurors' dichotomous verdict were found due to victim age, defendant age, or type of abuse, mock jurors provided higher guilt ratings when the abuse was sexual and both the victim and defendant were described as young adults. Similarly, mock jurors rated the victim more positively when the victim was described as a young adult (vs. child) for both sexual and physical abuse cases, and rated the defendant more positively when the victim was described as a child compared with young adult in sexual abuse cases. These findings suggest that mock jurors were largely influenced by victim age, particularly when the victim was described as an adult compared with a child.

Childhood maltreatment and Chinese adolescents' bullying and defending: The mediating role of moral disengagement.

Wang, Xingchao; Yang, Li; Gao, Ling; Yang, Jiping; Lei, Li; Wang, Caiyu

2017-07-01

In the present study, we tested the mediating role of moral disengagement in the effect of childhood maltreatment on bullying and defending. We also examined whether the mediating effect of moral disengagement differed between girls and boys, early and middle adolescents, as well as only and non-only children. Five hundred and fifty-two Chinese adolescents participated in this study. The results indicated that the prevalence rates of physical abuse, physical neglect, emotional abuse, and emotional neglect were 4.0%, 40.0%, 10.5%, and 27.9%, respectively. Path analysis showed that moral disengagement partially mediated the relation between childhood maltreatment and bullying, but did not mediate the relation between childhood maltreatment and defending. Moreover, multi-group analyses indicated that no significant path in the final model differed by gender. However, early adolescents exposed to high levels of childhood maltreatment were more likely to engage in bullying and less likely to engage in defending than middle adolescents, and early adolescents with high levels of moral disengagement were more likely to engage in bullying than middle adolescents. Compared to non-only children, only children exposed to high levels of childhood maltreatment were more likely to score higher on moral disengagement and less likely to engage in defending.

Jungert, Tomas; Piroddi, Barbara; Thornberg, Robert

2016-12-01

The aim of this study was to investigate whether various dimensions of student-teacher relationships were associated with different types of motivation to defend victims in bullying and to determine the association between these types of motivations and various bystander behaviors in bullying situations among early adolescents in Italy. Data were collected from 405 Italian adolescents who completed a survey in their classroom. Results showed that warm student-teacher relationships were positively associated with defending victims and with autonomous motivation to defend victims. In contrast, conflictual student-teacher relationships were positively associated with passive bystanding and with extrinsic motivation to defend victims. Different forms of motivation to defend were found to be mediators between student-teacher relationship qualities and bystander behaviors in school bullying. Our findings suggest that teachers should build warm and caring student-teacher relationships to enhance students' autonomous motivation to defend victims of bullying as well as their inclination to defend the victims in practice.

2007-04-01

In 1999, public defender (PD) representation of defendants appearing before Israel's juvenile courts began to be phased in. This article reports some of the major findings of a study that examined the impacts of the introduction of PDs. Analysis of interviews with 14 PDs yielded four major themes concerning the impact of the "arrival" of PDs, nature of the court, PDs' role, and PDs' interactions with other court actors. Analysis of interviews with eight prosecutors yielded seven themes concerning the need for PDs, PD as state agent, PDs' role, harms of legalization, disruption of the court, compromising the therapeutic value of the court hearing, and changes in court process. More generally, both PDs and prosecutors placed uncritical store in the value of rehabilitation alternatives. Indeed, the welfare model continues to shape their roles. The findings can largely be explained in terms of Eisenstein and Jacob's courtroom workgroup model.

Arbitrariness and the death penalty: how the defendant's appearance during trial influences capital jurors' punishment decision.

Antonio, Michael E

2006-01-01

This paper examines the impact of the defendant's appearance during the trial on capital jurors' punishment decision. The data used in this analysis were gathered by the Capital Jury Project (CJP), a national program of research on the decision-making of capital jurors. A series of multivariate logistic regression analyses were conducted using four aggravating circumstances related to the killing and eight defendant appearance variables as predictors of jurors' punishment decision at three points during the capital trial: (1) after the punishment phase ended, but before formal deliberation began; (2) when the first vote was taken on punishment at jury deliberations; and (3) at the final vote on punishment. Results indicated that when the defendant appeared emotionally involved during the trial (i.e. sorry and sincere) jurors either favored a life sentence or were undecided about punishment; however, when the defendant appeared emotionally uninvolved during the trial (i.e. bored) jurors either sought a death sentence or remained undecided. Policy implications will be discussed. Copyright (c) 2006 John Wiley & Sons, Ltd.

Structural bias in the sentencing of felony defendants.

PubMed

Sutton, John R

2013-09-01

As incarceration rates have risen in the US, so has the overrepresentation of African Americans and Latinos among prison inmates. Whether and to what degree these disparities are due to bias in the criminal courts remains a contentious issue. This article pursues two lines of argument toward a structural account of bias in the criminal law, focusing on (1) cumulative disadvantages that may accrue over successive stages of the criminal justice process, and (2) the contexts of racial disadvantage in which courts are embedded. These arguments are tested using case-level data on male defendants charged with felony crimes in urban US counties in 2000. Multilevel binary and ordinal logit models are used to estimate contextual effects on pretrial detention, guilty pleas, and sentence severity, and cumulative effects are estimated as conditional probabilities that are allowed to vary by race across all three outcomes. Results yield strong, but qualified, evidence of cumulative disadvantage accruing to black and Latino defendants, but do not support the contextual hypotheses. When the cumulative effects of bias are taken into account, the estimated probability of the average African American or Latino felon going to prison is 26% higher than that of the average Anglo.

2018-05-01

From October 2016 to September 2017, we performed tests of the ART-XC /SRG spare mirror system and detector unit at the 60-m-long IKI X-ray test facility. We describe some technical features of this test facility. We also present a brief description of the ART-XC mirror system and focal detectors. The nominal focal length of the ART-XC optics is 2700 mm. The field of view is determined by the combination of the mirror system and the detector unit and is equal to ˜0.31 square degrees. The declared operating energy range is 5-30 keV. During the tests, we illuminated the detector with a 55Fe+241 Am calibration source and also with a quasi-parallel X-ray beam. The calibration source is integrated into the detector's collimator. The X-ray beam was generated by a set of Oxford Instruments X-ray tubes with Cr, Cu and Mo targets and an Amptek miniature X-ray tube (Mini-X) with Ag transmission target. The detector was exposed to the X-ray beam either directly or through the mirror system. We present the obtained results on the detector's energy resolution, the muon on-ground background level and the energy dependence of the W90 value. The accuracy of a mathematical model of the ART-XC mirror system, based on ray-tracing simulations, proves to be within 3.5% in the main energy range of 4-20 keV and 5.4% in the "hard" energy range of 20-40 keV.

This paper describes the development of a Stirling Radioisotope Generator (SRG) Simulator for use in a prototype lunar robotic rover. The SRG developed at NASA Glenn Research Center (GRC) is a promising power source for the robotic exploration of the sunless areas of the moon. The simulator designed provides a power output similar to the SRG output of 5.7 A at 28 Vdc, while using ac wall power as the input power source. The designed electrical simulator provides rover developers the physical and electrical constraints of the SRG supporting parallel development of the SRG and rover. Parallel development allows the rover design team to embrace the SRG s unique constraints while development of the SRG is continued to a flight qualified version.

The purpose of this study was to determine the future, in terms of scientific publication, of medical thesis (MT) defended in the Medical School of Lille 2 University (MSL2U) between January 1st, 2001 and December 31st, 2007. The collection of MT published as a corresponding scientific article was realized from PubMed(®). For every corresponding article, we determined the journal Impact Factor (IF), the language of publication and the rank of the student and his MT director in the author list. Analyses were also realized according to the group of speciality of the TM. In all, 11.3% of the 2150 MT defended in the MSL2U were followed up by a scientific publication. The average IF was 2.32 with a median at 1.75 and extreme values from 0 to 14.78. Seventy percent of the articles were published in English. The rank of the student was placed before his MT director (2.06 vs. 3.15). The MT defended by students in the field of medical specialities presented the highest rate of publication (25.1%). The general medicine was the second speciality the most productive in term of number of published articles (n=49) after medical specialities (n=103). The MT director and the PhD students must be more motivated to publish their results. The value of 11.3% could be considered as weak but, because of a huge lack of references, it is impossible to compare our results to those of other French medical schools. It remains important to reform the objectives and the modalities of the writing of a MT: should we not have to turn to thesis called "on article"? Copyright © 2012. Published by Elsevier Masson SAS.

Defending spaceflight: The echoes of Apollo

NASA Astrophysics Data System (ADS)

Rovetto, R. J.

2016-12-01

This paper defends, and emphasizes the importance of, spaceflight, broadly construed to include human and unmanned spaceflight, space science, exploration and development. Within this discourse, I provide counter-replies to remarks by physicist Dr. Steven Weinberg against my previous support of human spaceflight. In this defense of peaceful spaceflight I draw upon a variety of sources. Although a focus is human spaceflight, human and unmanned modes must not be treated as an either-or opposition. Rather, each has a critical role to play in moving humanity forward as a spacefaring species. In the course of this communication, I also stress the perennial role of space agencies as science and technology-drivers, and their function to provide a stable and unified platform for space programs.

Effects of Mental Health and Neuroscience Evidence on Juror Perceptions of a Criminal Defendant: the Moderating Role of Political Orientation.

PubMed

Mowle, Elyse N; Edens, John F; Clark, John W; Sörman, Karolina

2016-11-01

Several recent studies have examined the effects of mental health and neuroscientific evidence on attitudes toward criminal defendants, suggesting that these factors may influence juror decision-making in meaningful ways. Few studies to date have manipulated both of these variables while also considering theoretically important individual difference variables (e.g., political orientation). Using a criminal case simulation, this study manipulated the presence of evidence concerning mental disorders (psychopathy and schizophrenia) and increasing levels of neuroscientific detail regarding a defendant's brain injury, and examined verdicts and sentencing recommendations in over 400 persons attending jury duty. Main effects were detected for mental health testimony and political orientation, although interactions were noted as well. More negative reactions to defendants labeled as psychopaths were relatively consistent, whereas participants who identified as liberal generally were less punitive towards a defendant identified as schizophrenic than were more conservative jurors. Consistent with other recent research, juror perceptions of the defendant's level of psychopathic traits (independent of the effects of the experimental manipulations) predicted guilty verdicts and longer sentencing recommendations.

Abortion, metaphysics and morality: a review of Francis Beckwith's defending life: a moral and legal case against abortion choice.

PubMed

Nobis, Nathan

2011-06-01

In Defending Life: A Moral and Legal Case Against Abortion Choice (2007) and an earlier article in this journal, "Defending Abortion Philosophically"(2006), Francis Beckwith argues that fetuses are, from conception, prima facie wrong to kill. His arguments are based on what he calls a "metaphysics of the human person" known as "The Substance View." I argue that Beckwith's metaphysics does not support his abortion ethic: Moral, not metaphysical, claims that are part of this Substance View are the foundation of the argument, and Beckwith inadequately defends these moral claims. Thus, Beckwith's arguments do not provide strong support for what he calls the "pro-life" view of abortion.

Rethinking Roe v. Wade: defending the abortion right in the face of contemporary opposition.

PubMed

Manninen, Bertha Alvarez

2010-12-01

In 2008, many states sought to pass Human Life Amendments, which would extend the definition of personhood to encompass newly fertilized eggs. If such an amendment were to pass, Roe v. Wade, as currently defended by the Supreme Court, may be repealed. Consequently, it is necessary to defend the right to an abortion in a manner that succeeds even if a Human Life Amendment successfully passes. J.J. Thomson's argument in "A Defense of Abortion" successfully achieves this. Her argument is especially strong when one considers that her central thesis-that one person's right to life does not entail the right to use another's person's body for continued sustenance-is pervasive in legal policies in the U.S.A.

Ants defend aphids against lethal disease

PubMed Central

Nielsen, Charlotte; Agrawal, Anurag A.; Hajek, Ann E.

2010-01-01

Social insects defend their own colonies and some species also protect their mutualist partners. In mutualisms with aphids, ants typically feed on honeydew produced by aphids and, in turn guard and shelter aphid colonies from insect natural enemies. Here we report that Formica podzolica ants tending milkweed aphids, Aphis asclepiadis, protect aphid colonies from lethal fungal infections caused by an obligate aphid pathogen, Pandora neoaphidis. In field experiments, bodies of fungal-killed aphids were quickly removed from ant-tended aphid colonies. Ant workers were also able to detect infective conidia on the cuticle of living aphids and responded by either removing or grooming these aphids. Our results extend the long-standing view of ants as mutualists and protectors of aphids by demonstrating focused sanitizing and quarantining behaviour that may lead to reduced disease transmission in aphid colonies.

2018-01-01

Computational models of cognitive processes may be employed in cyber-security tools, experiments, and simulations to address human agency and effective decision-making in keeping computational networks secure. Cognitive modeling can addresses multi-disciplinary cyber-security challenges requiring cross-cutting approaches over the human and computational sciences such as the following: (a) adversarial reasoning and behavioral game theory to predict attacker subjective utilities and decision likelihood distributions, (b) human factors of cyber tools to address human system integration challenges, estimation of defender cognitive states, and opportunities for automation, (c) dynamic simulations involving attacker, defender, and user models to enhance studies of cyber epidemiology and cyber hygiene, and (d) training effectiveness research and training scenarios to address human cyber-security performance, maturation of cyber-security skill sets, and effective decision-making. Models may be initially constructed at the group-level based on mean tendencies of each subject's subgroup, based on known statistics such as specific skill proficiencies, demographic characteristics, and cultural factors. For more precise and accurate predictions, cognitive models may be fine-tuned to each individual attacker, defender, or user profile, and updated over time (based on recorded behavior) via techniques such as model tracing and dynamic parameter fitting.

Classroom norms of bullying alter the degree to which children defend in response to their affective empathy and power.

Peets, Kätlin; Pöyhönen, Virpi; Juvonen, Jaana; Salmivalli, Christina

2015-07-01

This study examined whether the degree to which bullying is normative in the classroom would moderate associations between intra- (cognitive and affective empathy, self-efficacy beliefs) and interpersonal (popularity) factors and defending behavior. Participants were 6,708 third- to fifth-grade children (49% boys; Mage = 11 years) from 383 classrooms. Multilevel modeling analyses revealed that children were more likely to defend in response to their affective empathy in classrooms with high levels of bullying. In addition, popular students were more likely to support victims in classrooms where bullying was associated with social costs. These findings highlight the importance of considering interactions among individual and contextual influences when trying to understand which factors facilitate versus inhibit children's inclinations to defend others.

Protecting the fair trial rights of mentally disordered defendants in criminal proceedings: Exploring the need for further EU action.

PubMed

Verbeke, Peter; Vermeulen, Gert; Meysman, Michaël; Vander Beken, Tom

2015-01-01

Using the new legal basis provided by the Lisbon Treaty, the Council of the European Union has endorsed the 2009 Procedural Roadmap for strengthening the procedural rights of suspected or accused persons in criminal proceedings. This Roadmap has so far resulted in six measures from which specific procedural minimum standards have been and will be adopted or negotiated. So far, only Measure E directly touches on the specific issue of vulnerable persons. This Measure has recently produced a tentative result through a Commission Recommendation on procedural safeguards for vulnerable persons in criminal proceedings. This contribution aims to discuss the need for the introduction of binding minimum standards throughout Europe to provide additional protection for mentally disordered defendants. The paper will examine whether or not the member states adhere to existing fundamental norms and standards in this context, and whether the application of these norms and standards should be made more uniform. For this purpose, the procedural situation of mentally disordered defendants in Belgium and England and Wales will be thoroughly explored. The research establishes that Belgian law is unsatisfactory in the light of the Strasbourg case law, and that the situation in practice in England and Wales indicates not only that there is justifiable doubt about whether fundamental principles are always adhered to, but also that these principles should become more anchored in everyday practice. It will therefore be argued that there is a need for putting Measure E into practice. The Commission Recommendation, though only suggestive, may serve as a necessary and inspirational vehicle to improve the procedural rights of mentally disordered defendants and to ensure that member states are able to cooperate within the mutual recognition framework without being challenged on the grounds that they are collaborating with peers who do not respect defendants' fundamental fair trial rights

This paper presents a novel method for parallelizing the seeded region growing (SRG) algorithm using Compute Unified Device Architecture (CUDA) technology, with intention to overcome the theoretical weakness of SRG algorithm of its computation time being directly proportional to the size of a segmented region. The segmentation performance of the proposed CUDA-based SRG is compared with SRG implementations on single-core CPUs, quad-core CPUs, and shader language programming, using synthetic datasets and 20 body CT scans. Based on the experimental results, the CUDA-based SRG outperforms the other three implementations, advocating that it can substantially assist the segmentation during massive CT screening tests.

Race, law, and health: Examination of 'Stand Your Ground' and defendant convictions in Florida.

PubMed

Ackermann, Nicole; Goodman, Melody S; Gilbert, Keon; Arroyo-Johnson, Cassandra; Pagano, Marcello

2015-10-01

Previous analyses of Stand Your Ground (SYG) cases have been primarily descriptive. We examine the relationship between race of the victim and conviction of the defendant in SYG cases in Florida from 2005 to 2013. Using a regression analytic approach, we allow for simultaneous examination of multiple factors to better understand existing interrelationships. Data was obtained from the Tampa Bay Times SYG database (237 cases) which was supplemented with available online court documents and/or news reports. After excluding cases which were, still pending as of January 2015; had multiple outcomes (because of multiple suspects); and missing information on race of victim and weapon of victim, our final analytic sample has 204 cases. We chose whether the case resulted in a conviction as the outcome. We develop logistic regression models using significant bivariate predictors as candidates. These include race of the victim (White, non-White), whether the defendant could have retreated from the situation, whether the defendant pursued the victim, if the victim was unarmed, and who was the initiator of the confrontation. We find race of the victim to be a significant predictor of case outcome in this data set. After controlling for other variables, the defendant is two times (OR = 2.1, 95% CI [1.07, 4.10]) more likely to be convicted in a case that involves White victims compared to those involving non-White victims. Our results depict a disturbing message: SYG legislation in Florida has a quantifiable racial bias that reveals a leniency in convictions if the victim is non-White, which provides evidence towards unequal treatment under the law. Rather than attempting to hide the outcomes of these laws, as was done in Florida, other states with SYG laws should carry out similar analyses to see if their manifestations are the same as those in Florida, and all should remediate any injustices found.

Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies

NASA Technical Reports Server (NTRS)

2010-01-01

The United States spends approximately four million dollars each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth. The majority of this funding supports the operation of several observatories that scan the sky searching for NEOs. This, however, is insufficient in detecting the majority of NEOs that may present a tangible threat to humanity. A significantly smaller amount of funding supports ways to protect the Earth from such a potential collision or "mitigation." In 2005, a Congressional mandate called for NASA to detect 90 percent of NEOs with diameters of 140 meters of greater by 2020. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies identifies the need for detection of objects as small as 30 to 50 meters as these can be highly destructive. The book explores four main types of mitigation including civil defense, "slow push" or "pull" methods, kinetic impactors and nuclear explosions. It also asserts that responding effectively to hazards posed by NEOs requires national and international cooperation. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies is a useful guide for scientists, astronomers, policy makers and engineers.

Active defending and passive bystanding behavior in bullying: the role of personal characteristics and perceived peer pressure.

PubMed

Pozzoli, Tiziana; Gini, Gianluca

2010-08-01

This study examined the role of pro-victim attitudes, personal responsibility, coping responses to observations of bullying, and perceived peer normative pressure in explaining defending the victim and passive bystanding behavior in bullying. A total of 462 Italian early adolescents (mean age = 13.4 years, SD = 9 months) participated in the study. The behaviors were measured through two informants: each individual student and the teachers. The findings of a series of hierarchical regressions showed that, regardless of the informant, problem solving coping strategies and perceived peer normative pressure for intervention were positively associated with active help towards a bullied peer and negatively related to passivity. In contrast, distancing strategies were positively associated with passive bystanding, whereas they were negatively associated with teacher-reported defending behavior. Moreover, self-reported defending behavior was positively associated with personal responsibility for intervention, but only under conditions of low perceived peer pressure. Finally, the perception of peer pressure for intervention buffered the negative influence of distancing on passive bystanding tendencies. Future directions are discussed.

The aim of the present study was to examine whether the effect of empathy on the role children play in bullying situations, as either bullies, defenders or outsiders, was moderated by children's social status within their classroom, and whether this moderation was gender dependent. For this purpose, we used a representative sample of 2,050 Spanish primary school children (50.80% girls) from grades 3-6 (M age = 9.80 years; SD = 1.24), recruited from 27 primary schools. Results showed that the effect of empathy on bullying behavior was moderated by the sociometric rating only in girls. Both empathy and social rating had an effect on defending behavior. However, neither the children's sociometric rating nor their gender moderated the relationship between empathy and defending and outsider behaviors. These findings are discussed in terms of their implications for interventions designed to prevent bullying in school settings. © 2018 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Crime and Punishment: the Impact of Skin Color and Socioeconomic Status of Defendants and Victims in Jury Trials in Brazil.

Social judgments are often influenced by racism. Voluntary crimes against life, and in particular the crime of homicide, may be the most critical situations of the impact of racism in social judgments. We analyzed 114 homicide trials conducted by the 1st Jury Court, in a Brazilian judicial capital, concluded between 2003 and 2007, for the purpose of investigating the effects of skin color and the socioeconomic status of the defendant and the victim of homicides in the jury trial court's decision. The results indicate that the social and economic profile of defendants and victims of homicide is identical. They are almost all poor (more than 70%), with low education (more than 73%) and frequently non-Whites (more than 88%). We found that judges assign longer sentences to black (β = .34, p = .01) and poor defendants (β = .23, p < .05). We even verified that the poorer the defendant, the higher was the corresponding conviction rate (Wald's Test = 5.90, p < .05). The results are discussed based on theories of social psychology and criminological sociology, which consider the relationship between skin color and socioeconomic status in social judgments and in discrimination.

After exploring how criminal sanctions are actually employed by the courts against corporate defendants, the author argues that these sanctions are ineffective deterrents. Special problems which exist for the prosecutor or judge who attempts to invoke criminal sanctions against a corporate defendant raise questions about the feasibility and propriety of punishing the corporate entities and difficulties associated with proceeding against a corporate official or responsible individual within the corporate organization. The only way to makemore » the sanctions effective is to use them and to impose both fines and jail sentences on the guilty parties.« less

The steamed root of Rehmannia glutinosa has been used in traditional Oriental Medicine for treatment of inner ear diseases, such as tinnitus and hearing loss. In the present study, we showed that the ethanol extract of steamed roots of Rehmannia glutinosa (SRG) protected HEI-OC1 auditory cells from cisplatin cytotoxicity in a dose-dependent fashion. In addition, to investigate the protection mechanism of SRG on cisplatin cytotoxicity towards HEI-OC1, we measured the effects of SRG on lipid peroxidation of cisplatin treated cells as well as scavenging activities against superoxide radical, hydroxyl radical, hydrogen peroxide, and DPPH radical. SRG (5-100 microg/ml) had protective effect against the cisplatin-induced HEI-OC1 cell damage and reduced lipid peroxidation in a dose-dependent manner. Furthermore, SRG showed strong scavenging activity against superoxide radical, hydroxyl radical, hydrogen peroxide, and DPPH radical. These results indicate that SRG protects cisplatin-induced HEI-OC1 cell damage through inhibition of lipid peroxidation and scavenging activities of free radials.

Determining a Criminal Defendant's Competency to Proceed With an Extradition Hearing.

Piel, Jennifer; Finkle, Michael J; Giske, Megan; Leong, Gregory B

2015-06-01

When a criminal defendant flees from one state (often referred to as the requesting state) to another (often referred to as the asylum state), the requesting state can demand that the asylum state return the defendant through a process called extradition. Only a handful of states have considered a fugitive's right to be competent to proceed with an extradition hearing. Those states fall into three categories. Some states apply the same standard as in criminal trial competency cases. Others apply a more limited competency standard. Two have found that a fugitive has no right to be competent to proceed in an extradition hearing. The particular legal test adopted affects the nature and scope of the competency evaluation conducted by the psychiatrist or psychologist in the extradition hearing. In addition, we are not aware of any state that has considered what happens to the fugitive if he is ultimately found not competent to proceed. Legislation, either state by state or through amendments to the Uniform Criminal Extradition Act, can provide the legal and psychiatric communities with guidance in assessing competency initially and in taking appropriate steps if the fugitive is ultimately found not competent. © 2015 American Academy of Psychiatry and the Law.

The impact of defendant ethnicity on the psycholegal opinions of forensic mental health evaluators.

PubMed

McCallum, Katherine E; MacLean, Nina; Neil Gowensmith, W

2015-01-01

The impact of ethnicity on clinicians' decision making has received a great deal of attention and research. Several studies have documented that client ethnicity significantly influences diagnoses, testing and assessment protocols, recommendations for treatment, and expected outcomes. However, there is limited research examining the impact of a criminal defendant's ethnicity upon forensic mental health experts. To examine this issue, the authors reviewed 816 forensic reports on competency to stand trial submitted to the Hawaii judiciary between 2007 and 2008 and compared recommendation rates across categories of defendant ethnicity. Significant differences between ethnic groups were found in recommendations of competency to stand trial. Specifically, Asian misdemeanant populations were found to be incompetent to stand trial at higher rates than other ethnic groups. These findings highlight the potential impact that ethnicity may have on clinicians' decision making in certain forensic settings. Copyright © 2015 Elsevier Ltd. All rights reserved.

In the present study, the repellent effects of essential balm, a traditional medicine product in China, was tested against foraging and defending red imported fire ants, Solenopsis invicta Buren, under laboratory and field conditions. The laboratory study showed that both band- (width = 1 cm) and patch-smearing of essential balm at each concentration (0.5, 1, or 2 μl/cm(2)) significantly decreased the number of S. invicta foragers within the 6-h observation period. Moreover, band-smearing of 2 μl/cm(2) essential balm and patch-smearing of 0.5, 1, and 2 μl/cm(2) essential balm inhibited most S. invicta foraging activity at 3, 6, 6, and 24 h into the experiment, respectively. The field study showed that after a disturbance was created on the S. invicta mound, there were significantly less defending ants on the substance treated (patch-smeared) with 0.5, 1, and 2 μl/cm(2) essential balm than the controls, but the number of ants on the substance of these three concentrations was similar. Our study suggested that essential balm is a strong repellent against foraging and defending S. invicta and could be applied when temporary protection from S. invicta is needed. © The Authors 2016.

Jiménez-Naharro, Raúl; Gómez-Bravo, Fernando; Medina-García, Jonathan; Sánchez-Raya, Manuel; Gómez-Galán, Juan Antonio

2017-01-01

This paper presents a study about hardware attacking and clock signal vulnerability. It considers a particular type of attack on the clock signal in the I2C protocol, and proposes the design of a new sensor for detecting and defending against this type of perturbation. The analysis of the attack and the defense is validated by means of a configurable experimental platform that emulates a differential drive robot. A set of experimental results confirm the interest of the studied vulnerabilities and the efficiency of the proposed sensor in defending against this type of situation. PMID:28346337

Keep your bias to yourself: How deliberating with differently biased others affects mock-jurors' guilt decisions, perceptions of the defendant, memories, and evidence interpretation.

PubMed

Ruva, Christine L; Guenther, Christina C

2017-10-01

This experiment explored how mock-jurors' (N = 648) guilt decisions, perceptions of the defendant, memories, and evidence interpretation varied as a function of jury type and pretrial publicity (PTP); utilizing a 2 (jury type: pure-PTP vs. mixed-PTP) × 3 (PTP: defendant, victim, and irrelevant) factorial design. Mock-juries (N = 126) were composed of jurors exposed to the same type of PTP (pure-PTP; e.g., defendant-PTP) or different types of PTP (mixed-PTP; e.g., half exposed to defendant-PTP and half to irrelevant-PTP). Before deliberations jurors exposed to defendant-PTP were most likely to vote guilty; while those exposed to victim-PTP were least likely. After deliberations, jury type and PTP affected jurors' guilt decisions. Specifically, jurors deliberating on pure-PTP juries had verdict distributions that closely resembled the predeliberation distributions. The verdict distributions of jurors on mixed-PTP juries suggested that jurors were influenced by those they deliberated with. Jurors not exposed to PTP appeared to incorporate bias from PTP-exposed jurors. Only PTP had significant effects on postdeliberation measures of memory and evidence interpretation. Mediation analyses revealed that evidence interpretation and defendant credibility assessments mediated the effect of PTP on guilt ratings. Taken together these findings suggest that during deliberations PTP bias can spread to jurors not previously exposed to PTP. In addition, juries composed of jurors exposed to different PTP slants, as opposed to a single PTP slant, can result in less biased decisions. Finally, deliberating with others who do not share similar biases may have little, if any, impact on biased evidence interpretation or memory errors.

2015-12-01

This study aims (i) to understand how descriptive normative beliefs (DNB) about typical students' alcohol use and self-regulation (SRG) are related to alcohol use (AU) by exploring the indirect effect of SRG on AU through DNB and (ii) to explore gender differences and the differences between universities in DNB, SRG and AU. The cross-sectional data were collected online from 817 Slovak university students from four universities (75.22% females; Mage = 19.61; SD = 1.42), who filled in the AUDIT-C items, items measuring the DNB about typical students' AU and SRG. T-tests, one-way Anova and structural equation modelling were used for data analysis. Gender differences in AU and DNB were found with males having higher levels of both AU and DNB. The tested model of AU fits the data well. A significant association was found between DNB and (i) AU (positive) and (ii) SRG (negative). The analysis confirmed the existence of an indirect effect of SRG on AU through DNB. The study contributes to research concerning AU by the way in which DNB and SRG are linked to AU among Slovak university students. The research findings can also be used in developing prevention and intervention programs. © The Author 2014. Published by Oxford University Press on behalf of Faculty of Public Health.

``In the United States today science, as science, is under attack as never before (Defend Science, defendscience.org).'' Beyond, and underlying, the many particular attacks and outrages in different spheres and policy areas is the question of the scientific method and whether it is going to be upheld and applied, or whether -- even in the realm of science itself -- that method is going to be replaced by something antagonistically opposed to the scientific method. These attacks are increasingly coming from powerful forces, in and out of the Bush administration, with an extreme right-wing political agenda, a Biblical-literalist ideological agenda, and theocratic aspirations for society. Individual scientists may be atheists, agnostics, or may hold various religious beliefs, but if religious and theistic elements are forced into the definition of science, then the scientific process is undermined and science cannot really be practiced. We can and must develop a society wide battle, initiated by scientists, but involving ever growing masses of people to defend science and scientific thinking. Scientists from various fields must be mobilized to issue a public call to millions with this urgent message as the beginning of this effort. I will discuss the necessity, possibility, and some initial efforts toward developing this kind of societal movement in defense of science.

Defending psychopathy: an argument from values and moral responsibility.

PubMed

Malatesti, Luca; McMillan, John

2014-02-01

How psychopaths and their capacity for moral action are viewed is not only philosophically interesting but is also important and relevant for policy. The philosophical discussion of psychopathy has focussed upon the psychological faculties that are prerequisites for moral responsibility and empirical findings regarding psychopathy that are relevant to philosophical accounts of moral understanding and motivation. However, there are legitimate worries about whether psychopathy is a robust scientific construct, and there are risks attached to reifying psychopathy or other psychiatric constructs. We defend the concept of psychopathy by pointing out the relevance of empirical studies about it for our ordinary practices of ascribing moral responsibility and folk psychological accounts of moral understanding and motivation.

Evaluation of risk from acts of terrorism :the adversary/defender model using belief and fuzzy sets.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Darby, John L.

Risk from an act of terrorism is a combination of the likelihood of an attack, the likelihood of success of the attack, and the consequences of the attack. The considerable epistemic uncertainty in each of these three factors can be addressed using the belief/plausibility measure of uncertainty from the Dempster/Shafer theory of evidence. The adversary determines the likelihood of the attack. The success of the attack and the consequences of the attack are determined by the security system and mitigation measures put in place by the defender. This report documents a process for evaluating risk of terrorist acts using anmore » adversary/defender model with belief/plausibility as the measure of uncertainty. Also, the adversary model is a linguistic model that applies belief/plausibility to fuzzy sets used in an approximate reasoning rule base.« less

How Systems Engineering and Risk Management Defend Against Murphy's Law and Human Error

NASA Technical Reports Server (NTRS)

Bay, Michael; Connley, Warren

2004-01-01

Systems Engineering and Risk Management processes can work synergistically to defend against the causes of many mission ending failures. Defending against mission ending failures is facilitated by fostering a team that has a healthy respect for Murphy's Law and a team with a of curiosity for how things work, how they can fail, and what they need to know. This curiosity is channeled into making the unknowns known or what is uncertain more certain. Efforts to assure mission success require the expenditure of energy in the following areas: 1. Understanding what defines Mission Success as guided by the customer's needs, objectives and constraints. 2. Understanding how the system is supposed to work and how the system is to be produced, fueled by the curiosity of how the system should work and how it should be produced. 3. Understanding how the system can fail and how the system might not be produced on time and within cost, fueled by the curiosity of how the system might fail and how production might be difficult. 4. Understanding what we need to know and what we need learn for proper completion of the above three items, fueled by the curiosity of what we might not know in order to make the best decisions.

Qiu, Songgang; Peterson, Allen A.; White, Maurice A.; Faultersack, Franklyn; Redinger, Darin L.; Petersen, Stephen L.

2002-01-01

The Department of Energy (DOE) has selected Free-Piston Stirling Convertors as a technology for future advanced radioisotope space power systems. In August 2000, DOE awarded competitive Phase I, Stirling Radioisotope Generator (SRG) power system integration contracts to three major aerospace contractors, resulting in SRG conceptual designs in February 2001. All three contractors based their designs on the Technology Demonstration Convertor (TDC) developed by Stirling Technology Company (STC) for DOE. The contract award to a single system integration contractor for Phases II and III of the SRG program is anticipated in late 2001. The first potential SRG mission is targeted for a Mars rover. Recent TDC performance data are provided in this paper, together with predictions from Stirling simulation models. .

"Racial bias in mock juror decision-making: A meta-analytic review of defendant treatment": Correction to Mitchell et al. (2005).

2017-06-01

Reports an error in "Racial Bias in Mock Juror Decision-Making: A Meta-Analytic Review of Defendant Treatment" by Tara L. Mitchell, Ryann M. Haw, Jeffrey E. Pfeifer and Christian A. Meissner ( Law and Human Behavior , 2005[Dec], Vol 29[6], 621-637). In the article, all of the numbers in Appendix A were correct, but the signs were reversed for z' in a number of studies, which are listed. Also, in Appendix B, some values were incorrect, some signs were reversed, and some values were missing. The corrected appendix is included. (The following abstract of the original article appeared in record 2006-00971-001.) Common wisdom seems to suggest that racial bias, defined as disparate treatment of minority defendants, exists in jury decision-making, with Black defendants being treated more harshly by jurors than White defendants. The empirical research, however, is inconsistent--some studies show racial bias while others do not. Two previous meta-analyses have found conflicting results regarding the existence of racial bias in juror decision-making (Mazzella & Feingold, 1994, Journal of Applied Social Psychology, 24, 1315-1344; Sweeney & Haney, 1992, Behavioral Sciences and the Law, 10, 179-195). This research takes a meta-analytic approach to further investigate the inconsistencies within the empirical literature on racial bias in juror decision-making by defining racial bias as disparate treatment of racial out-groups (rather than focusing upon the minority group alone). Our results suggest that a small, yet significant, effect of racial bias in decision-making is present across studies, but that the effect becomes more pronounced when certain moderators are considered. The state of the research will be discussed in light of these findings. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Structure of p-shell nuclei using three-nucleon interactions evolved with the similarity renormalization group

Jurgenson, E. D.; Maris, P.; Furnstahl, R. J.; ...

2013-05-13

The similarity renormalization group (SRG) is used to soften interactions for ab initio nuclear structure calculations by decoupling low- and high-energy Hamiltonian matrix elements. The substantial contribution of both initial and SRG-induced three-nucleon forces requires their consistent evolution in a three-particle basis space before applying them to larger nuclei. While, in principle, the evolved Hamiltonians are unitarily equivalent, in practice the need for basis truncation introduces deviations, which must be monitored. Here we present benchmark no-core full configuration calculations with SRG-evolved interactions in p-shell nuclei over a wide range of softening. As a result, these calculations are used to assessmore » convergence properties, extrapolation techniques, and the dependence of energies, including four-body contributions, on the SRG resolution scale.« less

Cognitive functioning and adjudicative competence: defendants referred for neuropsychological evaluation in a psychiatric inpatient setting.

2017-11-01

A paucity of peer-reviewed research exists regarding the relation between cognitive functioning and adjudicative competence, despite increasing awareness of cognitive deficits associated with serious mental illness. This retrospective study sought to add to and expand upon existing research by considering performance validity and court determinations of competence, when available. We compared demographic and cognitive variables of a group of defendants with presumed valid testing admitted to an inpatient psychiatric facility for evaluation of adjudicative competence and referred for neuropsychological evaluation (n = 45) and compared individuals determined by the evaluator and/or the court to be competent (n = 30) and incompetent (n = 15). Defendants who were incompetent were more likely to be diagnosed with a cognitive disorder, with a medium effect size. There was a difference in tests of immediate and delayed memory as measured by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), with medium to large effects, and high delayed memory scores were helpful in ruling out incompetence (Negative predictive power = 85.71%). These results provide support for the relationship between cognitive functioning and trial competence, particularly at high and low levels of performance.

Defending strong tobacco packaging and labelling regulations in Uruguay: transnational tobacco control network versus Philip Morris International.

Crosbie, Eric; Sosa, Particia; Glantz, Stanton A

2018-03-01

Describe the process of enacting and defending strong tobacco packaging and labelling regulations in Uruguay amid Philip Morris International's (PMI) legal threats and challenges. Triangulated government legislation, news sources and interviews with policy-makers and health advocates in Uruguay. In 2008 and 2009, the Uruguayan government enacted at the time the world's largest pictorial health warning labels (80% of front and back of package) and prohibited different packaging or presentations for cigarettes sold under a given brand. PMI threatened to sue Uruguay in international courts if these policies were implemented. The Vazquez administration maintained the regulations, but a week prior to President Vazquez's successor, President Mujica, took office on 1 March 2010 PMI announced its intention to file an investment arbitration dispute against Uruguay in the International Centre for the Settlement of Investment Disputes. Initially, the Mujica administration announced it would weaken the regulations to avoid litigation. In response, local public health groups in Uruguay enlisted former President Vazquez and international health groups and served as brokers to develop a collaboration with the Mujica administration to defend the regulations. This united front between the Uruguayan government and the transnational tobacco control network paid off when Uruguay defeated PMI's investment dispute in July 2016. To replicate Uruguay's success, other countries need to recognise that strong political support, an actively engaged local civil society and financial and technical support are important factors in overcoming tobacco industry's legal threats to defend strong public health regulations. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Single Rapamycin Administration Induces Prolonged Downward Shift in Defended Body Weight in Rats

Manipulation of body weight set point may be an effective weight loss and maintenance strategy as the homeostatic mechanism governing energy balance remains intact even in obese conditions and counters the effort to lose weight. However, how the set point is determined is not well understood. We show that a single injection of rapamycin (RAP), an mTOR inhibitor, is sufficient to shift the set point in rats. Intraperitoneal RAP decreased food intake and daily weight gain for several days, but surprisingly, there was also a long-term reduction in body weight which lasted at least 10 weeks without additional RAP injection. These effects were not due to malaise or glucose intolerance. Two RAP administrations with a two-week interval had additive effects on body weight without desensitization and significantly reduced the white adipose tissue weight. When challenged with food deprivation, vehicle and RAP-treated rats responded with rebound hyperphagia, suggesting that RAP was not inhibiting compensatory responses to weight loss. Instead, RAP animals defended a lower body weight achieved after RAP treatment. Decreased food intake and body weight were also seen with intracerebroventricular injection of RAP, indicating that the RAP effect is at least partially mediated by the brain. In summary, we found a novel effect of RAP that maintains lower body weight by shifting the set point long-term. Thus, RAP and related compounds may be unique tools to investigate the mechanisms by which the defended level of body weight is determined; such compounds may also be used to complement weight loss strategy.

The initial flight prototype units are already undergoing performance tuning at STC. The new design will be hermetically scaled and will provide a weight reduction from approximately 4.8 kg to approximately 3.9 kg. .

Surface relief gratings: experiments, physical scenarios, and photoinduced (anomalous) dynamics of functionalized polymer chains

2017-10-01

Surface Relief Gratings (SRG) were demonstrated experimentally more than 20 years ago. Despite many years of research efforts the underlying physical mechanisms remain unclear. In this paper we present a short overview of the main concepts related to SRG - photofluidization and its counterpart, the orientational approach - based on a seminal paper by Saphiannikova et al. Next, we summarize the derivation of the cos2 θ potential, following the lines of recent paper of this group. Those results validate the generic Monte Carlo model for the photoinduced build-up of the density and SRG gratings in a model polymer matrix functionalized with azo-dyes, presented in another part of the paper. The characterization of the photoinduced motion of polymer chains, based on our recent paper, is briefly discussed in the last part of the paper. This discussion offers a sound insight into the mechanisms responsible for inscription of SRG as well as for single functionalized nanoparticle studies.

[Weight maintenance after weight loss - how the body defends its weight].

PubMed

Holzapfel, C; Hauner, H

2011-01-01

Mean weight loss of most conservative therapeutic weight loss programmes is about five to six kilograms after one year. In our "obesogenic" environment it is difficult for persons to maintain the new weight. Also continuation of the programme cannot prevent a moderate weight increase in the follow-up year. The reasons for this are not clear: individual lifestyle, environmental and genetic factors may play a role, but also the complex regulatory system of the body "to defend its weight". Nevertheless, for weight maintenance a lifelong change of lifestyle is of critical importance. Concerning nutrition a fat-reduced diet with a decrease of energy density together with regular eating habits and adequate portion size promises the greatest benefit and is likely to allow sufficient satiety. © Georg Thieme Verlag KG Stuttgart · New York.

Competence to waive interrogation rights and adjudicative competence in adolescent defendants: cognitive development, attorney contact, and psychological symptoms.

PubMed

Viljoen, Jodi L; Roesch, Ronald

2005-12-01

Although there is growing evidence of developmental differences in competency to waive interrogation rights and adjudicative competence, the correlates of adolescents' legal capacities remain unclear. This study examined the relationship of legal capacities to cognitive development, legal learning opportunities, and psychological symptoms. Participants were 152 male and female defendants aged 11-17, who completed Grisso's Instruments for Assessing Understanding and Appreciation of Miranda Rights, the Fitness Interview Test (Revised Edition), the Woodcock-Johnson III Cognitive Assessment Battery, and the Brief Psychiatric Rating Scale for Children. Legal capacities relevant to interrogation and adjudication increased with age. These developmental differences were partially mediated or explained by cognitive development. Of the specific cognitive abilities examined (general intellectual ability, verbal ability, reasoning, long-term retrieval, attention, and executive functioning), verbal ability was a particularly strong predictor of performance on competency measures. Also, defendants obtained lower scores on competency measures if they showed evidence of attention deficits or hyperactivity, had spent limited time with their attorneys, and/or were from low socioeconomic backgrounds.

Defending Against Advanced Persistent Threats Using Game-Theory

PubMed Central

König, Sandra; Schauer, Stefan

2017-01-01

Advanced persistent threats (APT) combine a variety of different attack forms ranging from social engineering to technical exploits. The diversity and usual stealthiness of APT turns them into a central problem of contemporary practical system security, since information on attacks, the current system status or the attacker’s incentives is often vague, uncertain and in many cases even unavailable. Game theory is a natural approach to model the conflict between the attacker and the defender, and this work investigates a generalized class of matrix games as a risk mitigation tool for an advanced persistent threat (APT) defense. Unlike standard game and decision theory, our model is tailored to capture and handle the full uncertainty that is immanent to APTs, such as disagreement among qualitative expert risk assessments, unknown adversarial incentives and uncertainty about the current system state (in terms of how deeply the attacker may have penetrated into the system’s protective shells already). Practically, game-theoretic APT models can be derived straightforwardly from topological vulnerability analysis, together with risk assessments as they are done in common risk management standards like the ISO 31000 family. Theoretically, these models come with different properties than classical game theoretic models, whose technical solution presented in this work may be of independent interest. PMID:28045922

Defenders and Challengers of Endothelial Barrier Function

PubMed Central

Rahimi, Nader

2017-01-01

Regulated vascular permeability is an essential feature of normal physiology and its dysfunction is associated with major human diseases ranging from cancer to inflammation and ischemic heart diseases. Integrity of endothelial cells also play a prominent role in the outcome of surgical procedures and organ transplant. Endothelial barrier function and integrity are regulated by a plethora of highly specialized transmembrane receptors, including claudin family proteins, occludin, junctional adhesion molecules (JAMs), vascular endothelial (VE)-cadherin, and the newly identified immunoglobulin (Ig) and proline-rich receptor-1 (IGPR-1) through various distinct mechanisms and signaling. On the other hand, vascular endothelial growth factor (VEGF) and its tyrosine kinase receptor, VEGF receptor-2, play a central role in the destabilization of endothelial barrier function. While claudins and occludin regulate cell–cell junction via recruitment of zonula occludens (ZO), cadherins via catenin proteins, and JAMs via ZO and afadin, IGPR-1 recruits bullous pemphigoid antigen 1 [also called dystonin (DST) and SH3 protein interacting with Nck90/WISH (SH3 protein interacting with Nck)]. Endothelial barrier function is moderated by the function of transmembrane receptors and signaling events that act to defend or destabilize it. Here, I highlight recent advances that have provided new insights into endothelial barrier function and mechanisms involved. Further investigation of these mechanisms could lead to the discovery of novel therapeutic targets for human diseases associated with endothelial dysfunction. PMID:29326721

Setting aside a historiography that has tended to focus on the arguments of antivivisectionists, it reconstructs the viewpoint of the scientific community through an examination of Romanes's work to help orchestrate the defense of animal experimentation. By embedding his life in three complicatedly overlapping networks-the world of print, interpersonal communications among an increasingly professionalized body of scientific men, and the intimacies of private life-the essay uses Romanes as a lens with which to focus the physiological apprehension of the antivivisection movement. It is a story of reputation, self-interest, and affection.

The present study evaluates the knowledge of jury-eligible college students (n = 192), investigative interviewers (n = 44), forensic psychologists (n = 39), and public defenders (n = 137) in regard to the research on interviewing children. These groups' knowledge was compared with the scientific research on the impact of interview techniques and practices on the accuracy of child witnesses. Jury-eligible students were the least knowledgeable, but their accuracy varied widely across items. Both interviewers and public defenders performed better than jury-eligible students, but they lacked substantial knowledge about the research on interviewing children on certain topics (e.g., using anatomically detailed dolls); forensic psychologists were the most knowledgeable. These findings suggest that professionals in the legal system need substantial professional development regarding the research on interviewing strategies with child witnesses. They also highlight the need for experts to provide case-relevant information to juries who lack basic information about the validity and reliability of children's reports.

Roth, Mary Ellen; Schreiber, Jeffrey G.; Pepper, Stephen V.

2004-01-01

A high-efficiency 110 watt Stirling Radioisotope Generator 110 (SRG110) is being developed for potential NASA exploration missions. The SRG system efficiency is greater than 20%, making it an attractive candidate power system for deep space missions and unmanned rovers. The Department of Energy SRG110 Project team consists of the System Integrator, Lockheed Martin (LM), Stirling Technology Company (STC), and NASA Glenn Research Center (GRC). One of the GRC roles is to provide Independent Verification and Validation of the Stirling TDC's. At the request of LM, a part of this effort includes the extended operation of the TDC's in the dynamically balanced dual-opposed configuration. Performance data of the Stirling Converters over time is required to demonstrate that an SRG110 can meet long-duration mission requirements. A test plan and test system were developed to evaluate TDC's #13 and #14 steady-state performance for a minimum of 5000 hours and insure safe, round-the-clock operation of the TDC's. This paper will discuss the design and development, and status of the Extended Operation Test.

To share or not to share? The contribution of self-disclosure to stress-related growth among suicide survivors.

PubMed

Levi-Belz, Yossi

2016-08-01

This study examined to what extent suicide survivors can experience growth in the aftermath of suicide loss, as well as the role of self-disclosure and coping strategies in stress-related growth (SRG) among suicide survivors, compared to bereavement following sudden and expected death types. One hundred forty-five bereaved individuals (aged 18-73) completed questionnaires measuring SRG, self-disclosure, and coping strategies. Significant interaction between self-disclosure and types of death was found, in which suicide survivors with low levels of self-disclosure manifested the lowest level of SRG compared to other subgroups. This finding suggests that sharing intimate information can be beneficial in struggling with a situation of suicide in the family.

Defending the indefensible? Psychiatry, assisted suicide and human freedom.

PubMed

Parker, Malcolm

2013-01-01

The siege guns of the forces for change to euthanasia and assisted suicide laws have been pounding for decades, but the longstanding proscription on these practices has held out in all but a few jurisdictions. A few psychiatrists have enlisted with the challengers, but many remain on the battlements, defending the impermissibility of active assistance in dying. Given the long history of the separation of church and state and the significant secularisation of society; the recognition by the law of both acts and omissions as legal causes; lenient sentences for mercy killers; critiques of the "psychiatriatisation" of different aspects of life; and the consistency of public opinion, this recalcitrant stand bespeaks undercurrents and positions that are often by rationalised or camouflaged, and which call for exploration. In this paper, I examine connections between psychiatry and conceptualisations of harm, suffering and natural death; medicalisation, psychiatrisation and medical paternalism; decision-making capacity, rationality and diagnosis; recent legal developments; social pluralism; and religious intuitionism. I conclude that psychiatrists and the psychiatry profession, concerned as they are with enlarging the province of human freedom, should begin a more transparent rapprochement with those they would repel.

Hanlon, Robert E; Rubin, Leah H; Jensen, Marie; Daoust, Sarah

2010-02-01

Neuropsychological features of 77 indigent murder defendants and death row inmates were examined in relation to criminal variables underlying their homicidal acts. Clinically, the sample was characterized by elevated rates of developmental disorders (49%), personality disorders (54%), Axis I psychiatric disorders (45%), substance abuse (86%), and history of violence (43%). By statute, killing more than one person is an aggravating factor in many jurisdictions that renders a murder defendant eligible for the death penalty. Individuals who committed a single murder were characterized by executive dysfunction, lower intelligence, slower speed of information processing, and a higher frequency of developmental disorders (58%), relative to those charged and/or convicted of killing two or more people, who were characterized by a significantly higher rate of personality disorders (79%) and a lower rate of developmental disorders (34%). Additionally, using the FBI criminal classification system for categorizing homicide by motive, a significant difference in the frequency of psychosis was found among subgroups associated with the following motives: Criminal enterprise; personal cause; and sex. The collective neuropsychological profile of the sample revealed that executive functions were significantly decreased, relative to memory functions, with over half of the sample (55%) demonstrating executive dysfunction.

Triarchic Model Personality Traits and Their Impact on Mock Juror Perceptions of a White-Collar Criminal Defendant.

PubMed

Rulseh, Allison; Edens, John F; Cox, Jennifer

2017-01-01

The triarchic model of psychopathy proposes that this personality disorder is composed of 3 relatively distinct constructs: meanness, disinhibition, and boldness. Although the first 2 components are widely accepted, boldness has generated considerable theoretical debate concerning its relevance-largely due to its association with various ostensibly adaptive characteristics and socially desirable behaviors (e.g., self-reported heroism). But is being bold actually perceived by others as an intrinsically adaptive, socially desirable personality trait? We investigated this question using a novel approach-a jury simulation study that manipulated the level of triarchic traits exhibited by a white-collar criminal. More specifically, 330 community members read a vignette in which the defendant's degree of boldness and disinhibition was manipulated and then provided sentence recommendations and other evaluative ratings. As hypothesized, manipulating boldness and disinhibition resulted in more negative views of the defendant, with the boldness manipulation more consistently predicting higher global psychopathy, "meanness," and "evil" ratings. Surprisingly, neither manipulation predicted sentence recommendations, although higher global psychopathy ratings did correlate with more punitive sentence recommendations. The presence of personality traits construed in some contexts as advantageous or socially desirable can be perceived as more dysfunctional and undesirable in other contexts-particularly when they cooccur with criminal behavior.

Plaintiff or defendant: using legal cases to teach students pharmacy law.

PubMed

Spies, Alan R

2008-10-15

To demonstrate the value of students using actual legal cases during collaborative "breakout" sessions in a pharmacy law class. Students were broken into smaller groups and randomly assigned a legal case to arbitrate or defend. One week prior to the groups' presentation, all students were given the facts of a case that was reflective of issues covered during the lecture component of the course. Formative assessments were utilized in addition to an overall breakout satisfaction survey administered at the end of the course. Overall, students felt the breakout sessions enhanced their learning environment and reinforced material covered during the didactic portion of the course. Students also recommended the breakout sessions for future pharmacy law courses. Dividing a large pharmacy law class into 2 sections of 12 groups each and conducting mock trials resulted in increased student participation and interaction and deeper understanding of the course content.

Gall volatiles defend aphids against a browsing mammal

PubMed Central

2013-01-01

Background Plants have evolved an astonishing array of survival strategies. To defend against insects, for example, damaged plants emit volatile organic compounds that attract the herbivore’s natural enemies. So far, plant volatile responses have been studied extensively in conjunction with leaf chewing and sap sucking insects, yet little is known about the relationship between plant volatiles and gall-inducers, the most sophisticated herbivores. Here we describe a new role for volatiles as gall-insects were found to benefit from this plant defence. Results Chemical analyses of galls triggered by the gregarious aphid Slavum wertheimae on wild pistachio trees showed that these structures contained and emitted considerably higher quantities of plant terpenes than neighbouring leaves and fruits. Behavioural assays using goats as a generalist herbivore confirmed that the accumulated terpenes acted as olfactory signals and feeding deterrents, thus enabling the gall-inducers to escape from inadvertent predation by mammals. Conclusions Increased emission of plant volatiles in response to insect activity is commonly looked upon as a “cry for help” by the plant to attract the insect’s natural enemies. In contrast, we show that such volatiles can serve as a first line of insect defences that extends the ‘extended phenotype’ represented by galls, beyond physical boundaries. Our data support the Enemy hypothesis insofar that high levels of gall secondary metabolites confer protection against natural enemies. PMID:24020365

Regarding the methodological approach, 68.4% used qualitative methods. The data evidenced the contributions of this Program to research.

Defending the Doomed: Implicit Strategies Concerning Protection of First-Person Shooter Games

PubMed Central

Munko, Daniel; Glock, Sabine; Bente, Gary

2012-01-01

Abstract Censorship of violent digital games, especially first-person shooter (FPS) games, is broadly discussed between generations. While older people are concerned about possible negative influences of these games, not only players but also nonplayers of the younger net-generation seem to deny any association with real aggressive behavior. Our study aimed at investigating defense mechanisms players and nonplayers use to defend FPS and peers with playing habits. By using a lexical decision task, we found that aggressive concepts are activated by priming the content of FPS but suppressed afterward. Only if participants were instructed to actively suppress aggressive concepts after priming, thought suppression was no longer necessary. Young people still do have negative associations with violent video games. These associations are neglected by implicitly applying defense strategies—independent of own playing habits—to protect this specific hobby, which is common for the net-generation. PMID:22515170

Lunar Gravity-Assist Maneuver As a Way of Reducing the Orbit Amplitude in the Spectrum-Röntgen-Gamma Project

Kovalenko, I. D.; Eismont, N. A.

2018-04-01

Spectrum-Röntgen-Gamma (SRG) is a space observatory designed to observe astrophysical objects in the X-ray range of the electromagnetic spectrum. SRG is planned to be launched in 2019 by a Proton-M launch vehicle with a DM3 upper stage. The spacecraft will be delivered to an orbit around the Sun-Earth collinear libration point L2 located at a distance of 1.5 million km from the Earth. Although the SRG launch scheme has already been determined at present, in this paper we consider an alternative spacecraft transfer scenario using a lunar gravity-assist maneuver. The proposed scenario allows a oneimpulse transfer from a low Earth orbit to a small-amplitude orbit around the libration point to be performed while fulfilling the technical constraints and the scientific requirements of the mission.

Ask the Experts: How Can New Students Defend Behavior Analysis from Misunderstandings?

PubMed

Becirevic, Amel

2014-10-01

The success of behavior analysis as a field depends on the successes of its students, researchers, practitioners, and advocates. A new generation of graduate students will ultimately speak on the behalf of the field. In order to further promote the field, students must not only learn about what behavior analysis is, but also about what behavior analysis is not. We must prepare ourselves to adequately defend behavior analysis from those who disseminate misperceptions and misunderstandings. As such, an electronic survey designed to glean some information on how behavior analysts would respond to various inaccuracies or misunderstandings of behavior analysis was distributed through behavior-analytic listservs and social media websites. Findings show that the majority of respondents indicate that any graduate student ought to correct the misunderstandings about the field. What do seasoned behavior analysts have to say about the majority opinion about the responsibilities of graduate students and what recommendations do they have for new graduate students who come across misunderstandings about behavior analysis?

Reliable appropriate topology design for multiple-processor systems

A Shift and Replace Graph which is a very appropriate candidate for the topology of a multiple-processor system is a function of two positive integers r and m, and is denoted as SRF(r,m). Pradhan and Reddy proved that the node connectivity of SRG(r,m) is at least r and also give a routing algorithm which generally requires 2m jumps if the number of node failures is no larger than r - 1. Later, Esfahanian and Hakimi proved that SRG(r,m) has maximum node connectivity 2r - 2 and give routing algorithms which require: (1) at most m + 3 + log/sub r/mmore » jumps if 3 + log/sub r/m does not exceed m and the number of node failures is at most r - 1; (2) at most m + 5 + log/sub r/m jumps if 4 + log/sub r/m less than or equal to m and the number of node failures if less than or equal to 2r - 3; (3) all the other situations require no more than 2m jumps. By modifying the SRG(r,m), it is first proved that node connectivity of SRG(r,m) can be increased to: (1) 2r - 1 when r = 2, m = 2, and (2) 2r when (r = 2, m > 2) or (r > 2, m greater than or equal to 2, m greater than or equal to 2). The routing algorithms are also given for the modified SRG (r,m), which require at most 2m + 3 jumps when the number of node failures is less than or equal to 2r - 1.« less

Analyses a three-phase 12/8 switched reluctance generator (SRG) which is based on its structure and performance principle. The initial size data were calculated by MathCAD, and the simulation model was set up in the ANSOFT software environment with the maximum efficiency and the maximum output power as the main reference parameters. The outer diameter of the stator and the inner diameter of the rotor were parameterized. The static magnetic field distribution, magnetic flux, magnetic energy, torque, inductance characteristics, back electromotive force and phase current waveform of SRG is obtained by analyzing the static magnetic field and the steady state motion of two-dimensional transient magnetic field in ANSOFT environment. Finally, the experimental data of the prototype are compared with the simulation results, which provide a reliable basis for the design and research of SRG wind turbine system.

The expert witness: defending the profession or prosecuting your peers.

The use of CRNAs as expert witnesses in court cases is well-established. The CRNA who acts as a legal consultant or an expert witness is not retained merely to pontificate in the courtroom based on their considerable experience and expertise. The CRNA will undertake many roles in the process of assisting the attorney including those of (1) record reviewer and data analyst, (2) researcher and retriever, (3) synthesizer, and (4) teacher. Beyond these roles is the philosophical premise that the person best suited to evaluate the competence of a nurse anesthetist is another nurse anesthetist. Poor practitioners who are a danger to the public ought to be held accountable for their failings, whereas excellent practitioners who are mistakenly accused of negligence ought to be defended. Although challenging and time consuming, the role of the legal consultant and expert witness is rewarding in both financial and personal satisfaction terms. The role and functions of the CRNA who takes on the challenges of appearing as an expert witness or legal consultant is explored. The fine points of medical malpractice is not discussed, except as a cursory overview. The goal is to provide the practicing CRNA with the basic tools needed for these roles.

A unique latex protein, MLX56, defends mulberry trees from insects.

2009-05-01

The mulberry (Morus spp.)-silkworm (Bombyx mori) relationship has been a well-known plant-herbivore interaction for thousands of years. Recently, we found that mulberry leaves defend against insect herbivory by latex ingredients. Here we report that a 56-kDa (394 amino acid) defense protein in mulberry latex designated mulatexin (MLX56) with an extensin domain, two hevein-like chitin-binding domains, and an inactive chitinase-like domain provides mulberry trees with strong insect resistance. MLX56 is toxic to lepidopteran caterpillars, including the cabbage armyworm, Mamestra brassicae and the Eri silkworm, Samia ricini, at 0.01% concentration in a wet diet, suggesting that MLX56 is applicable for plant protection. MLX56 is highly resistant to protease digestion, and has a strong chitin-binding activity. Interestingly, MLX56 showed no toxicity to B. mori, suggesting that the mulberry specialist has developed adaptation to the mulberry defense. Our results show that defensive proteins in plant latex play key roles in mulberry-insect interactions, and probably also in other plant-insect interactions. Our results further suggest that plant latexes analogous to animal venom contain a treasury of applicable defense proteins and chemicals that has evolved through inter-specific interactions.

Accelerated Life Structural Benchmark Testing for a Stirling Convertor Heater Head

Krause, David L.; Kantzos, Pete T.

2006-01-01

For proposed long-duration NASA Space Science missions, the Department of Energy, Lockheed Martin, Infinia Corporation, and NASA Glenn Research Center are developing a high-efficiency, 110 W Stirling Radioisotope Generator (SRG110). A structurally significant limit state for the SRG110 heater head component is creep deformation induced at high material temperature and low stress level. Conventional investigations of creep behavior adequately rely on experimental results from uniaxial creep specimens, and a wealth of creep data is available for the Inconel 718 material of construction. However, the specified atypical thin heater head material is fine-grained with a heat treatment that limits precipitate growth, and little creep property data for this microstructure is available in the literature. In addition, the geometry and loading conditions apply a multiaxial stress state on the component, far from the conditions of uniaxial testing. For these reasons, an extensive experimental investigation is ongoing to aid in accurately assessing the durability of the SRG110 heater head. This investigation supplements uniaxial creep testing with pneumatic testing of heater head-like pressure vessels at design temperature with stress levels ranging from approximately the design stress to several times that. This paper presents experimental results, post-test microstructural analyses, and conclusions for four higher-stress, accelerated life tests. Analysts are using these results to calibrate deterministic and probabilistic analytical creep models of the SRG110 heater head.

A novel fiber-optical vibration defending system with on-line intelligent identification function

2013-09-01

Capacity of the sensor network is always a bottleneck problem for the novel FBG-based quasi-distributed fiberoptical defending system. In this paper, a highly sensitive sensing network with FBG vibration sensors is presented to relieve stress of the capacity and the system cost. However, higher sensitivity may cause higher Nuisance Alarm Rates (NARs) in practical uses. It is necessary to further classify the intrusion pattern or threat level and determine the validity of an unexpected event. Then an intelligent identification method is proposed by extracting the statistical features of the vibration signals in the time domain, and inputting them into a 3-layer Back-Propagation(BP) Artificial Neural Network to classify the events of interest. Experiments of both simulation and field tests are carried out to validate its effectiveness. The results show the recognition rate can be achieved up to 100% for the simulation signals and as high as 96.03% in the real tests.

We present first ab initio no-core shell model (NCSM) calculations using similarity renormalization group (SRG) transformed chiral two-nucleon (NN) plus three-nucleon (3N) interactions for nuclei throughout the p-shell, particularly (12)C and (16)O. By introducing an adaptive importance truncation for the NCSM model space and an efficient JT-coupling scheme for the 3N matrix elements, we are able to surpass previous NCSM studies including 3N interactions. We present ground and excited states in (12)C and (16)O for model spaces up to N(max) = 12 including full 3N interactions. We analyze the contributions of induced and initial 3N interactions and probe induced 4N terms through the sensitivity of the energies on the SRG flow parameter. Unlike for light p-shell nuclei, SRG-induced 4N contributions originating from the long-range two-pion terms of the chiral 3N interaction are sizable in (12)C and (16)O.

Evaluation of Candidate Materials for a High-Temperature Stirling Convertor Heater Head

NASA Technical Reports Server (NTRS)

Bowman, Randy; Ritzert, Frank; Freedman, Marc

2003-01-01

The Department of Energy (DOE) and NASA have identified Stirling Radioisotope Generators (SRG) as a candidate power system for use on long-duration, deep-space science missions and Mars rovers. One of the developments planned for an upgraded version of the current SRG design is to achieve higher efficiency by increasing the overall operating temperature of the system. Currently, the SRG operates with a heater head temperature of 650 C and is fabricated from the nickel base superalloy 718. This temperature is at the limit of Alloy 718's capability, and any planned increase in temperature will be contingent on identifying a more capable material from which to fabricate the heater head. To this end, an assessment of material candidates was performed assuming a range of heater head temperatures. The chosen alternative material candidates will be discussed, along with the development efforts needed to ensure that these materials can meet the demanding system requirements of long-duration operation in hostile environments.

2016-01-01

In recent years social and news media have increasingly been used to explain patterns in disease activity and progression. Social media data, principally from the Twitter network, has been shown to correlate well with official disease case counts. This fact has been exploited to provide advance warning of outbreak detection, forecasting of disease levels and the ability to predict the likelihood of individuals developing symptoms. In this paper we introduce DEFENDER, a software system that integrates data from social and news media and incorporates algorithms for outbreak detection, situational awareness and forecasting. As part of this system we have developed a technique for creating a location network for any country or region based purely on Twitter data. We also present a disease nowcasting (forecasting the current but still unknown level) approach which leverages counts from multiple symptoms, which was found to improve the nowcasting accuracy by 37 percent over a model that used only previous case data. Finally we attempt to forecast future levels of symptom activity based on observed user movement on Twitter, finding a moderate gain of 5 percent over a time series forecasting model. PMID:27192059

The information about the health losses among the population of Leningrad as a result of bombing, shelling and disease is given. Extremely high rates of morbidity and mortality in residents were associated with hunger, hypothermia and emotional stress. The clinical picture of some diseases has different peculiarities because of alimentary dystrophy background. The city health service suffered huge losses: 482 medical institutions were destroyed, only about 300 people from 1.5 thousand of medical personnel in 1942 saved working capability. The health care service of the local air defense played an essential role in delivery of medical aid. The contribution of civil and military health workers in saving residents lives in the blockaded Leningrad was appreciated.

The purpose of the current study was to determine if peer reactions to aggression among preschool youth were consistent with those conceptualized in the adolescent bullying literature as defenders, encouragers, and neutral bystanders. Direct observations were used to document patterns for types of peer-directed aggression in early childhood settings to ascertain interaction differences between individuals involved within the bullying dynamic. Observations of 50 students in preschool were conducted over 5.5 months. Event recording procedures were used to document aggressive behaviors and reactions from peers and teachers. Results indicated that the majority of aggression was physical. Additionally, peer reactions, as described in the bullying literature for school-aged youth, occurred very infrequently. Peer aggression tended to be more physical, suggesting that early childhood educators should attend to these physical interactions, and cultivate a classroom community that emphasizes social supports and appropriate interactions.

Videotaped material is used for educational purposes in many areas of medicine. In forensic facilities, programs designed to restore competency to stand trial (CST) in incompetent, mentally ill defendants have utilized videotaped courtroom proceedings as learning tools. This pilot study reviewed the progress of incompetent defendants (N = 15) who participated in a program that utilized videotaped segments of the television crime-drama "Law & Order", among other techniques, to promote CST in individuals deemed unfit to stand trial. The authors hypothesized that participation in at least one cycle of the Competency Restoration Group (CRG)'s curriculum would be associated with improvement in the areas of understanding, reasoning and appreciation. In order to assess whether the group was beneficial to the patient's treatment goal of competency restoration, patients were screened using the MacArthur Competence Assessment Tool-Criminal Adjudication (MacCAT-CA) prior to starting the group and after completing a cycle of the group's curriculum. The Wilcoxon signed ranks test was employed to analyze the results from the pre- and post-group MacCAT-CA testing. The tests yielded significant (p < 0.005) post-test differences in the hypothesized direction for each of the three subsections: Understanding, Reasoning, and Appreciation as well as a significant post test improvement in the total MacCAT-CA scores. These results suggest that a didactic program, using a popular crime drama series, can be effective in facilitating learning in competency restoration programs. Limitations of this study include its lack of a control group and small population.

2015-10-01

The In-Medium Similarity Renormalization Group (IM-SRG) has been applied successfully not only to several closed shell finite nuclei, but has recently been used to produce effective shell model interactions that are competitive with phenomenological interactions in the SD shell. A recent alternative method for solving of the IM-SRG equations, called the Magnus expansion, not only provides a computationally feasible route to producing observables, but also allows for approximate handling of induced three-body forces. Promising results for several systems, including finite nuclei, will be presented and discussed.

In the shark rectal gland (SRG), apical chloride secretion through CFTR channels is electrically coupled to a basolateral K + conductance whose type and molecular identity are unknown. We performed studies in the perfused SRG with 17 K + channel inhibitors to begin this search. Maximal chloride secretion was markedly inhibited by low-perfusate pH, bupivicaine, anandamide, zinc, quinidine, and quinine, consistent with the properties of an acid-sensitive, four-transmembrane, two-pore-domain K + channel (4TM-K2P). Using PCR with degenerate primers to this family, we identified a TASK-1 fragment in shark rectal gland, brain, gill, and kidney. Using 5' and 3' rapid amplification of cDNA ends PCR and genomic walking, we cloned the full-length shark gene (1,282 bp), whose open reading frame encodes a protein of 375 amino acids that was 80% identical to the human TASK-1 protein. We expressed shark and human TASK-1 cRNA in Xenopus oocytes and characterized these channels using two-electrode voltage clamping. Both channels had identical current-voltage relationships (outward rectifying) and a reversal potential of -90 mV. Both were inhibited by quinine, bupivicaine, and acidic pH. The pKa for current inhibition was 7.75 for shark TASK-1 vs. 7.37 for human TASK-1, values similar to the arterial pH for each species. We identified this protein in SRG by Western blot and confocal immunofluorescent microscopy and detected the protein in SRG and human airway cells. Shark TASK-1 is the major K + channel coupled to chloride secretion in the SRG, is the oldest 4TM 2P family member identified, and is the first TASK-1 channel identified to play a role in setting the driving force for chloride secretion in epithelia. The detection of this potassium channel in mammalian lung tissue has implications for human biology and disease. Copyright © 2016 the American Physiological Society.

2005-01-01

An advantage of using a Radioisotope Power System (RPS) for deep space or planetary surface missions is the readily available waste heat, which can be used for a number of beneficial purposes including: maintaining electronic components within a controlled temperature range, warming propulsion tanks and mobility actuators, and maintaining liquid propellants above their freezing temperature. Previous missions using Radioisotope Thermoelectric Generators (RTGs) dissipated large quantities of waste heat due to the low efficiency of the thermoelectric conversion technology. The next generation RPSs, such as the 110-Watt Stirling Radioisotope Generator (SRG110) will have higher conversion efficiencies, thereby rejecting less waste heat at a lower temperature and may require alternate approaches to transferring waste heat to the spacecraft. RTGs, with efficiencies of 6 to 7 percent, reject their waste heat at the relatively high heat rejection temperature of 200 C. This is an advantage when rejecting heat to space; however, transferring heat to the internal spacecraft components requires a large and heavy radiator heat exchanger. At the same time, sensitive spacecraft instruments must be shielded from the thermal radiation of the RTG. The SRG110, with an efficiency around 22 percent and 50 C nominal housing surface temperature, can readily transfer the available waste heat directly via heat pipes, thermal straps, or fluid loops. The lower temperatures associated with the SRG110 avoid the chances of overheating other scientific components, eliminating the need for thermal shields. This provides the spacecraft designers more flexibility when locating the generator for a specific mission. A common misconception with high-efficiency systems is that there is not enough waste heat for spacecraft thermal management. This paper will dispel this misconception and investigate the use of a high-efficiency SRG110 for spacecraft thermal management and outline potential methods of

The importance of calf sensory and physical preferences for starter concentrates during pre- and postweaning periods.

We performed 3 studies to evaluate the effects of feed sensory and form preferences in young calves on performance and rumen fermentation dynamics. In experiment 1, starter feeds containing wheat and soybean meal; wheat and canola meal; and oats and soybean meal were evaluated in 63 calves (9±0.9 d old). In experiment 2, 37 crossbreed female calves were used from 4 to 45 d of age (weaning) in a cafeteria study consisting of 4 different presentations of the same starter feed: meal, pellet, pellet mixed with whole-cereal grains (WHG), and pellet mixed with steamed-rolled cereal grains (SRG). In experiment 3, 63 Holstein male calves (10±1.03 d old) were randomly distributed to 2 treatments that consisted of feeding a pellet concentrate mixed with whole corn and barely grains (WHG) or the same pellet concentrate mixed with steamed-rolled corn and barley grains (SRG). In experiment 1, animals in all 3 treatments had similar intake and performance, and we found no differences in rumen fermentation parameters. In experiment 2, during the first week of study, calves had a greater preference for WHG; after the first week, calves had a greater preference for SRG. In experiment 3, starter concentrate intake was greater in WHG than in SRG concentrates between wk 5 and weaning. However, we observed no differences in growth or gain-to-feed ratio. Calves offered WHG concentrates had greater rumen pH and tended to have lower total rumen volatile fatty acid concentrations than those offered SRG concentrates. We concluded that preweaned calves preferred concentrates based on pellets mixed with steamed-rolled grains. When calves could not choose their starter feed, pellets mixed with steamed-rolled grains reduced concentrate intake and rumen pH compared to pellets mixed with whole grains, but performance was not impaired. Formulating starter concentrates according to calves' sensory and physical preferences had little effect on performance. Copyright © 2016 American Dairy Science

Power, Process, and Protection: Juveniles as Defendants in the Justice System.

PubMed

Woolard, Jennifer L; Henning, Kristin; Fountain, Erika

The juvenile court was created in 1899 in part to remedy the unfairness of trying youth in the adult criminal justice system, but its success at rectifying those problems is unclear. One concern is that the vast majority of youth who are adjudicated delinquent are adjudicated after waiving their right to trial and entering a guilty plea. Fairness and equity in the plea bargaining process are premised on the assumption that youth have the capacity to understand and elect between available options and will be given a meaningful opportunity to choose without coercion and deception. In legal terms, the Constitution will only sanction a plea when the defendant makes a knowing, voluntary, and intelligent waiver of her right to trial. In this chapter, we briefly describe the juvenile court process and explain the circumstances of a plea bargain, which constitutes both a waiver of Constitutional rights and an agreement to certain conditions. Then we evaluate the research and practice knowledge regarding the legal components of a valid waiver-that it must be knowing and voluntary. We consider how information, capacity, and circumstance contribute to a knowing waiver. Then we examine how procedural justice, paternalism, and coercion may affect a voluntary waiver. Throughout, we consider whether the people, policies, and practices meant to assess and safeguard that waiver decision fulfill their intended purpose. © 2016 Elsevier Inc. All rights reserved.

The impact of the WHO Framework Convention on Tobacco Control in defending legal challenges to tobacco control measures.

PubMed

Zhou, Suzanne Y; Liberman, Jonathan D; Ricafort, Evita

2018-06-02

Since the WHO Framework Convention on Tobacco Control's (FCTC) entry into force, the tobacco industry has initiated litigation challenging tobacco control measures implemented by governments around the world, or supported others to initiate such litigation on its behalf. In defending their tobacco control measures against such litigation, governments have invoked their obligations and rights under the WHO FCTC. We assess the extent to which the WHO FCTC has provided legal weight to governments' defences against legal challenge. We reviewed 96 court decisions concerning legal challenges to tobacco control measures, determining whether or not they cited the WHO FCTC and their outcomes. We then reviewed the cases where the WHO FCTC was cited, analysing how the WHO FCTC contributed to the resolution of the case. The WHO FCTC was cited in 45 decisions. Decisions both citing and not citing the WHO FCTC were largely decided in favour of governments, with 80% of WHO-FCTC-citing and 67% of non-WHO-FCTC-citing cases upholding the measure in its entirety and on every ground of challenge. In cases where it was cited, the WHO FCTC contributed to the resolution of the case in favour of governments by providing a legal basis for measures, demonstrating the measure's public health purpose, demonstrating the evidence in favour of a measure, demonstrating international consensus, demonstrating that a measure promotes or protects health-related human rights and demonstrating whether or not a measure is reasonable, proportionate or justifiable. The way the WHO FCTC has been cited in court decisions suggests that it has made a substantial contribution to courts' reasoning in tobacco control legal challenges and has strengthened government's arguments in defending litigation. © World Health Organization 2018.

The feasibility of medical management for select patients with acute type A aortic dissection has been reported from a few institutions. In this study, we retrospectively investigated the safety and feasibility of our conservative approach for patients with type A aortic dissection in daily practice. From January 2013 to December 2017, 131 consecutive patients were admitted to our institution for acute aortic dissection, including 58 patients of type A. Initial medical management was attempted in select patients who were clinically stable and had a thrombosed false lumen of the ascending aorta without ulcer-like projections in the ascending aorta. Except for nine patients contraindicated for surgery, urgent surgery was performed in 26 patients (SRG group), while 23 patients (MED group) were treated with the initial medical management. The maximum diameter of the ascending aorta was significantly larger in the SRG group than in the MED group. In the MED group, the heart rate and blood pressures were well-controlled at admission to the intensive-care unit, and the systolic blood pressure was further reduced at 24 h after. The in-hospital mortality rates of the MED and SRG groups were 0% and 15%, respectively. During the follow-up period, the survival rate was significantly higher in the MED group than in the SRG group, and the aortic event-free survival at one year was 80%. The initial medical management for select patients with a thrombosed false lumen in the ascending aorta was a safe and feasible strategy in real-world practice.

Addition and Removal Energies via the In-Medium Similarity Renormalization Group Method

NASA Astrophysics Data System (ADS)

Yuan, Fei

The in-medium similarity renormalization group (IM-SRG) is an ab initio many-body method suitable for systems with moderate numbers of particles due to its polynomial scaling in computational cost. The formalism is highly flexible and admits a variety of modifications that extend its utility beyond the original goal of computing ground state energies of closed-shell systems. In this work, we present an extension of IM-SRG through quasidegenerate perturbation theory (QDPT) to compute addition and removal energies (single particle energies) near the Fermi level at low computational cost. This expands the range of systems that can be studied from closed-shell ones to nearby systems that differ by one particle. The method is applied to circular quantum dot systems and nuclei, and compared against other methods including equations-of-motion (EOM) IM-SRG and EOM coupled-cluster (CC) theory. The results are in good agreement for most cases. As part of this work, we present an open-source implementation of our flexible and easy-to-use J-scheme framework as well as the HF, IM-SRG, and QDPT codes built upon this framework. We include an overview of the overall structure, the implementation details, and strategies for maintaining high code quality and efficiency. Lastly, we also present a graphical application for manipulation of angular momentum coupling coefficients through a diagrammatic notation for angular momenta (Jucys diagrams). The tool enables rapid derivations of equations involving angular momentum coupling--such as in J-scheme--and significantly reduces the risk of human errors.

Ginsenoside Rg3 regulates S-nitrosylation of the NLRP3 inflammasome via suppression of iNOS

DOE Office of Scientific and Technical Information (OSTI.GOV)

Yoon, Sung-Jin; Park, Jun-Young; Department of Functional Genomics, University of Science and Technology, Yuseong-gu, Daejeon

Ginsenoside Rg3, a specific biological effector, is well-known as a major bioactive ingredient of Panax ginseng. However, its role in the inflammasome activation process remains unclear. In this report, we demonstrate that ginsenosides 20(R)-Rg3 and 20(S)-Rg3 are capable of suppressing both lethal endotoxic shock and the S-nitrosylation of the NLRP3 inflammasome by inhibiting nitric oxide (NO) production through the regulation of inducible nitric oxide synthase (iNOS) expression. In response to lipopolysaccharide (LPS), the reducing effect of 20(S)-Rg3 and 20(R)-Rg3 on nitric oxide led to an increase in the survival time of mice after lethal endotoxin-induced shock, and excess levels ofmore » NO inhibited IL-1β production via the S-nitrosylation of the NLRP3 inflammasome. In addition, ginsenosides 20(R)-Rg3 and 20(S)-Rg3 had suppressive effects on the LPS- or UV-irradiation-induced reactive oxygen species (ROS) levels in macrophage and HaCaT cells and thereby prevented apoptosis of spleen cells in mice. Altogether, these results demonstrate that ginsenoside 20(R)-Rg3 and 20(S)-Rg3, a naturally occurring compound, might act as a dual therapeutic regulator for the treatment of inflammatory and oxidative stress-related diseases. - Highlights: • Ginsenosides Rg3 inhibits NO production through the regulation of iNOS expression. • Ginsenosides Rg3 inhibits the S-nitrosylation of the NLRP3 inflammasome. • Ginsenosides Rg3 suppress on the LPS- or UV-irradiation-induced ROS levels in cells.« less

Dendritic azo compounds as a new type amorphous molecular material with quick photoinduced surface-relief-grating formation ability

2008-09-01

A series of dendritic azobenzene-containing compounds have been synthesized as a new type amorphous molecular material, which can show quick surface-relief-grating (SRG) formation ability upon light irradiation. For the synthesis, the dendritic precursor tris(2-(ethyl(phenyl)amino)ethyl)benzene-1,3,5-tricarboxylate and tris(3,5-bis(2-(ethyl(phenyl)amino)ethoxy)benzyl)benzene-1,3,5-tricarboxylate were prepared by esterification reactions between 1,3,5-benzenetricarbonyl chloride and N-ethyl- N-hydroxyethyl-aniline and 3,5-bis[2-( N-ethylanilino)ethoxy] benzylalcohol. The precursors were, respectively reacted with the diazonium salts of 4-nitroaniline, 4-aminobenzoic acid, and 4-aminobenzonitrile to introduce different types of donor-acceptor azo chromophores at the peripheral positions. The structure and properties of the dendritic azo compounds were characterized by the spectroscopic methods and thermal analysis. The surface-relief-grating (SRG) formation behavior of the dendritic azo compounds was studied by exposing the spin-coated thin films to an interference pattern of laser beams (532 nm) at modest intensity (100 mW/cm 2). The results show that the azo compounds can form stable amorphous glasses in a broad temperature range. The glass transition temperatures ( Tgs) depend on the backbone structures and the type of the peripheral azo chromophors. The type of the electron withdrawing groups in the p-positions of the terminal azobenzene units shows a significant influence on the SRG inscription rate. For the compounds containing the same type azo chromophores, the SRG inscription rate is also affected by the backbone structure.

Sacoglossans are characterized by the ability to sequester functional chloroplasts from their algal diet through a process called kleptoplasty, enabling them to photosynthesize. The bacterial diversity associated with sacoglossans is not well understood. In this study, we coupled traditional cultivation-based methods with 454 pyrosequencing to examine the bacterial communities of the chemically defended Hawaiian sacoglossan Elysia rufescens and its secreted mucus. E. rufescens contains a defense molecule, kahalalide F, that is possibly of bacterial origin and is of interest because of its antifungal and anticancer properties. Our results showed that there is a diverse bacterial assemblage associated with E. rufescens and its mucus, with secreted mucus harboring higher bacterial richness than entire-E. rufescens samples. The most-abundant bacterial groups affiliated with E. rufescens and its mucus are Mycoplasma spp. and Vibrio spp., respectively. Our analyses revealed that the Vibrio spp. that were highly represented in the cultivable assemblage were also abundant in the culture-independent community. Epifluorescence microscopy and matrix-assisted laser desorption–ionization mass spectrometry (MALDI-MS) were utilized to detect the chemical defense molecule kahalalide F on a longitudinal section of the sacoglossan.

A Parametric System Model (PSM) was created in order to explore conceptual designs, the impact of component changes and power level on the performance of the Stirling Radioisotope Generator (SRG). Using the General Purpose Heat Source (GPHS approximately 250 Wth) modules as the thermal building block from which a SRG is conceptualized, trade studies are performed to understand the importance of individual component scaling on isotope usage. Mathematical relationships based on heat and power throughput, temperature, mass, and volume were developed for each of the required subsystems. The PSM uses these relationships to perform component- and system-level trades.

Rejecting the Baby Doe rules and defending a "negative" analysis of the Best Interests Standard.

Two incompatible policies exist for guiding medical decisions for extremely premature, sick, or terminally ill infants, the Best Interests Standard and the newer, 20-year old "Baby Doe" Rules. The background, including why there were two sets of Baby Doe Rules, and their differences with the Best Interests Standard, are illustrated. Two defenses of the Baby Doe Rules are considered and rejected. The first, held by Reagan, Koop, and others, is a "right-to-life" defense. The second, held by some leaders of the American Academy of Pediatrics, is that the Baby Doe Rules are benign and misunderstood. The Baby Doe Rules should be rejected since they can thwart compassionate and individualized decision-making, undercut duties to minimize unnecessary suffering, and single out one group for treatment adults would not want for themselves. In these ways, they are inferior to the older Best Interests Standard. A "negative" analysis of the Best Interests Standard is articulated and defended for decision-making for all incompetent individuals.

Like other Latin American democratic societies, Chile is supposed to respect legal rights of mentally ill people who are in trouble with the law, and provide them protection, treatment and welfare. Therefore, in this decade, the Chilean Criminal Justice and Mental Health System has undergone significant changes. Because this article is related to the recent social features that involve different areas such as justice, mental health assistance and forensic psychiatry systems, and thereby the nonexistence of current literature that reviews this matter from a global perspective and its implications for the mental health population involved in the justice system, its review and analysis seems to be interesting. The 'New Forensic Psychiatry Network' (NFPN) has been putting in relevant efforts to offer proper treatment and forensic assessment taking into account the civil rights of mentally insane people, and the 'Criminal Justice System Reform' (CJSR) is making possible legal conditions for better justice ensuring a more just resolution of insane defendants' and mentally ill convicts' lawsuits. From the author's viewpoint, all these changes are leading to a deep cultural impact on a Chilean's mind, changing their vision of justice and how society should respect insane defendants' and mentally ill convicts' legal rights.

Defending Oneself From Tourists: The Counter-Environmental Bubble

According to the Environmental Bubble Theory, tourists perform a series of strategies in order to remain anchored to their residential spots. The environmental bubble is constituted by a sort of social pellicule able to immunize tourists from the identity/cultural attacks which the visit to a foreign country implies. Such a pellicule is activated by the tourists themselves as they decide to travel in group or, for example, to eat only at the restaurants proposing their own national cuisine, and so on. Generally the potential cultural shock of residents is not taken into consideration in literature, even if it is plausibile to make the hypothesis of a counter-environmental bubble performed by the residents in order to defend their own culture and their identity from the attacks of mass tourism, especially for cities that live on tourism, as, for example, Florence or Siena do. Our study aims at testing the access to local tradition made available in promotional material. The hypothesis we propose is that there should exist a difference in promoting cultural heritage and intimate culture. The intimate culture refers to the living culture, the way of living, comprehending cuisine, education, religion, the way by which the role of females and males are performed, and so on. On the other hand, the cultural heritage, or historical culture, makes reference to a culture meant as belonging to the whole mankind, as it happens, for example, for archeological sites or museums. In more detail, we propose the hypothesis that the intimate culture is maintained unaccessible for tourists' gaze, or at least accessible only in the shape of a spectacularized event, the so called pseudo-event of Boorstin. Using the software NUD*IST we analyzed the promotional material of the city of Siena. Our results confirm Boorstin's theory about pseudo-events realized for tourists.

Defending the social value of knowledge as a safeguard for public trust.

PubMed

Holzer, Felicitas S

2017-09-01

The 'socially valuable knowledge' (SVK) principle has been widely acknowledged as one of the most important guiding principles for biomedical research involving human subjects. The principle states that the potential of producing socially valuable knowledge is a necessary requirement, although not sufficient, for the ethical conduct of research projects. This is due to the assumption that the social value of knowledge avoids exploitation of research subjects and justifies the use of health resources. However, more recently, several authors have started interrogating the validity of SVK in research and offered various lines of argument against the SVK principle as a necessary constraint to research. In this article, I will reconstruct the main arguments of this discussion between defenders and debunkers of the SVK principle and offer a third way to consider the social value of knowledge in research studies. I will argue that the social value of knowledge can be supported by an independent justification. This justification of the SVK principle addresses the rationality and common interest of researchers. Thus, I will introduce the SVK principle as a safeguarding principle for public trust based on a conceptual framework by Alex John London. My approach justifies keeping the principle as a precautionary and rational requirement for human health research that all rational stakeholders can agree upon. © 2017 John Wiley & Sons Ltd.

The Department of Energy, Lockheed Martin, Stirling Technology Company (STC), and the NASA Glenn Research Center are developing a high-efficiency Stirling Radioisotope Generator (SRG) for NASA space science missions. The SRG is being developed for multimission use, including providing electric power for unmanned Mars rovers and deep space missions. On Mars, rovers with SRGs would be used for missions that might not be able to use photovoltaic power systems, such as exploration at high Martian latitudes and missions of long duration. The projected SRG system efficiency of 23 percent will reduce the required amount of radioisotope by a factor of 4 or more in comparison to currently used Radioisotope Thermoelectric Generators. The Department of Energy recently named Lockheed Martin as the system integration contractor. Lockheed Martin has begun to develop the SRG engineering unit under contract to the Department of Energy, and has contract options to develop the qualification unit and the first flight units. The developers expect the SRG to produce about 114 Wdc at the beginning of mission, using two opposed Stirling convertors and two General Purpose Heat Source modules. STC previously developed the Stirling convertor under contract to the Department of Energy and is now providing further development as a subcontractor to Lockheed Martin. Glenn is conducting an in-house technology project to assist in developing the convertor for space qualification and mission implementation. A key milestone was recently reached with the accumulation of 12 000 hr of long-term aging on two types of neodymium-iron boron permanent magnets. These tests are characterizing any possible aging in the strength or demagnetization resistance of the magnets used in the linear alternator. Preparations are underway for a thermal/vacuum system demonstration and unattended operation during endurance testing of the 55-We Technology Demonstration Convertors. In addition, Glenn is developing a

PubMed Central

Rogan, Slavko

2015-01-01

Background: High intensity intermittent aerobic exercise is an elementary endurance training exercise to build soccer endurance. Many studies exist with professional soccer players. But limited research has been conducted with amateur soccer players. Objectives: The aim of this study was to compare and assess the effects of the shuttle-run method and the Hoff-track method on the ability to recover in amateur soccer players within three weeks. Patients and Methods: Two amateur soccer teams were randomly assigned to shuttle-run group (n = 24; SRG) (SRG: shuttle-run group) or Hoff-track group (n = 18; HTG) (HTG: hoff-track group). They performed 2 times/week over three weeks their program. SRG performed a 20 m high speed shuttle-run until exhaustion and HTG covered at their highest speed level an obstacle track. Before and after training the yo-yo intermittent recovery test level 2 (YYIRTL2) was conducted. Results: Significant differences were observed within (P < 0.05) and between the groups (P = 0.06; ES = 0.50) in distance covering during YYIRTL2. Conclusions: Both training methods seem to improve the ability to recover in amateur soccer players within a short time period during the competition season. PMID:26448831

Improving the In-Medium Similarity Renormalization Group via approximate inclusion of three-body effects

2016-09-01

The In-Medium Similarity Renormalization Group (IM-SRG) has been applied successfully to the ground state of closed shell finite nuclei. Recent work has extended its ability to target excited states of these closed shell systems via equation of motion methods, and also complete spectra of the whole SD shell via effective shell model interactions. A recent alternative method for solving of the IM-SRG equations, based on the Magnus expansion, not only provides a computationally feasible route to producing observables, but also allows for approximate handling of induced three-body forces. Promising results for several systems, including finite nuclei, will be presented and discussed.

The objective of the present study was to analyze the results of research reported in the theses for the degree in "forensic medicine" defended in different dissertation committees during the 5 year period (from 2010 till 2014) and to summarize and compartmentalize the main research areas in which the authors carried out their study and thereby make the data obtained more readily available for the wide circles of readers. A total of 55 theses for the scientific degree in "forensic medicine" (14.03.05) were defended during the period from 2010 till 2014 including 18 (32.7%) ones for the degree in two disciplines, the second being either "pathological anatomy" (n=6) or "stomatology" (n=4). Despite the great variety of the problems resolved in the studies conducted during the five year period, the subject matter of most research was on the whole consistent with the main lines of activities of the institutions with which the degree-seeking workers were affiliated. The same refers to the choice of the tutors and scientific advisers. the authors emphasize the necessity of centralized planning of research in compliance with the list of priority investigations having practical significance and coordination of cooperative studies carried out based on the state bureau of forensic medical expertise (SBFME) and departments of forensic medical expertise of medical universities.

This interdisciplinary research, drawing on cognitive psychology and linguistics, extended to middle childhood past research during early childhood or adulthood on thinking aloud prior to written composing. In year 5 of a longitudinal study of typical writing, when cohort 1 was in grade 5 ( n = 110 ten year-olds) and cohort 2 in grade 7 ( n = 97 twelve year-olds), a cross-sectional study was conducted. Children were first asked to think aloud while they generated ideas and second while they planned their essays to express and defend their opinions on a controversial topic in the region of the United States where they lived. Third, they wrote their essays. Their think-aloud protocols were audio-recorded and later transcribed into writing for analysis. The authors developed and applied rating scales for quality of idea generating and planning in the written transcriptions and quality of opinion expression, opinion defense, organization, and content in the essays children wrote after thinking aloud; total number of words in essays was also counted. Seventh graders scored significantly higher than fifth graders on quality of idea generation but not planning, and higher on all variables rated for quality in the written essays including length. Quality of expressing opinions and defending opinions were uncorrelated in grade 5, but moderately correlated in grade 7. Whether idea generating or planning quality explained unique variance in essays varied with coded written essay variables and grade. Educational applications of results for assessment, assessment-instruction links, instruction in social studies, and theory of mind in persuasive essay writing are discussed.

Legal insanity is a peculiar element of criminal law, because it brings together two very different disciplines: psychiatry and psychology on the one hand and the law on the other. One of the basic questions regarding evaluations of defendants concerns the question of who should establish “true mental disorder,” the judge or the behavioral expert? This question is complicated, and in this contribution it will be explored based on a Dutch case that was eventually decided by the European Court of Human Rights (ECtHR). We will argue that the ECtHR provides a valuable legal framework. Based on its merits, the framework could also be of interest to countries outside the Court’s jurisdiction. PMID:29085306

Utilizing Radioisotope Power System Waste Heat for Spacecraft Thermal Management

NASA Technical Reports Server (NTRS)

Pantano, David R.; Dottore, Frank; Geng, Steven M.; Schrieber, Jeffrey G.; Tobery, E. Wayne; Palko, Joseph L.

2005-01-01

One of the advantages of using a Radioisotope Power System (RPS) for deep space or planetary surface missions is the readily available waste heat, which can be used to maintain electronic components within a controlled temperature range, to warm propulsion tanks and mobility actuators, and to gasify liquid propellants. Previous missions using Radioisotope Thermoelectric Generators (RTGs) dissipated a very large quantity of waste heat due to the relatively low efficiency of the thermoelectric conversion technology. The next generation RPSs, such as the 110-watt Stirling Radioisotope Generator (SRG110) will have much higher conversion efficiencies than their predecessors and therefore may require alternate approaches to transferring waste heat to the spacecraft. RTGs, with efficiencies of approx. 6 to 7% and 200 C housing surface temperatures, would need to use large and heavy radiator heat exchangers to transfer the waste heat to the internal spacecraft components. At the same time, sensitive spacecraft instruments must be shielded from the thermal radiation by using the heat exchangers or additional shields. The SRG110, with an efficiency around 22% and 50 C nominal housing surface temperature, can use the available waste heat more efficiently by more direct heat transfer methods such as heat pipes, thermal straps, or fluid loops. The lower temperatures allow the SRG110 much more flexibility to the spacecraft designers in configuring the generator without concern of overheating nearby scientific instruments, thereby eliminating the need for thermal shields. This paper will investigate using a high efficiency SRG110 for spacecraft thermal management and outline potential methods in several conceptual missions (Lunar Rover, Mars Rover, and Titan Lander) to illustrate the advantages with regard to ease of assembly, less complex interfaces, and overall mass savings.

Benchmark Calibration Tests Completed for Stirling Convertor Heater Head Life Assessment

Krause, David L.; Halford, Gary R.; Bowman, Randy R.

2005-01-01

A major phase of benchmark testing has been completed at the NASA Glenn Research Center (http://www.nasa.gov/glenn/), where a critical component of the Stirling Radioisotope Generator (SRG) is undergoing extensive experimentation to aid the development of an analytical life-prediction methodology. Two special-purpose test rigs subjected SRG heater-head pressure-vessel test articles to accelerated creep conditions, using the standard design temperatures to stay within the wall material s operating creep-response regime, but increasing wall stresses up to 7 times over the design point. This resulted in well-controlled "ballooning" of the heater-head hot end. The test plan was developed to provide critical input to analytical parameters in a reasonable period of time.

Simple turbulence measurements with azopolymer thin films.

2013-04-01

A simple method to measure the influence on the laser beam propagation by a turbid medium is proposed. This measurement is based on the inscription of a surface relief grating (SRG) on an azopolymer thin film. The grating obtained with a single laser beam after propagation into a turbulent medium is perturbed and directly analyzed by a CCD camera through its diffraction pattern. Later, by scanning the surface pattern with an atomic force microscope, the inscribed SRG is analyzed with the Radon transform. This method has the advantage of using a single beam to remotely inscribe a grating detecting perturbations during the beam path. A method to evaluate the refractive index constant structure is developed.

GRC Supporting Technology for NASA's Advanced Stirling Radioisotope Generator (ASRG)

Schreiber, Jeffrey G.; Thieme, Lanny G.

2008-01-01

From 1999 to 2006, the NASA Glenn Research Center (GRC) supported a NASA project to develop a high-efficiency, nominal 110-We Stirling Radioisotope Generator (SRG110) for potential use on NASA missions. Lockheed Martin was selected as the System Integration Contractor for the SRG110, under contract to the Department of Energy (DOE). The potential applications included deep space missions, and Mars rovers. The project was redirected in 2006 to make use of the Advanced Stirling Convertor (ASC) that was being developed by Sunpower, Inc. under contract to GRC, which would reduce the mass of the generator and increase the power output. This change would approximately double the specific power and result in the Advanced Stirling Radioisotope Generator (ASRG). The SRG110 supporting technology effort at GRC was replanned to support the integration of the Sunpower convertor and the ASRG. This paper describes the ASRG supporting technology effort at GRC and provides details of the contributions in some of the key areas. The GRC tasks include convertor extended-operation testing in air and in thermal vacuum environments, heater head life assessment, materials studies, permanent magnet characterization and aging tests, structural dynamics testing, electromagnetic interference and electromagnetic compatibility characterization, evaluation of organic materials, reliability studies, and analysis to support controller development.

Propagation Modeling and Defending of a Mobile Sensor Worm in Wireless Sensor and Actuator Networks

WSANs (Wireless Sensor and Actuator Networks) are derived from traditional wireless sensor networks by introducing mobile actuator elements. Previous studies indicated that mobile actuators can improve network performance in terms of data collection, energy supplementation, etc. However, according to our experimental simulations, the actuator’s mobility also causes the sensor worm to spread faster if an attacker launches worm attacks on an actuator and compromises it successfully. Traditional worm propagation models and defense strategies did not consider the diffusion with a mobile worm carrier. To address this new problem, we first propose a microscopic mathematical model to describe the propagation dynamics of the sensor worm. Then, a two-step local defending strategy (LDS) with a mobile patcher (a mobile element which can distribute patches) is designed to recover the network. In LDS, all recovering operations are only taken in a restricted region to minimize the cost. Extensive experimental results demonstrate that our model estimations are rather accurate and consistent with the actual spreading scenario of the mobile sensor worm. Moreover, on average, the LDS outperforms other algorithms by approximately 50% in terms of the cost. PMID:28098748

The 'common knowledge' of Quebecers: quantifying the evidence of historians testifying for defendant tobacco companies.

PubMed

Callard, Cynthia

2016-09-01

The 'common knowledge' defence is a legal strategy which has been successfully used by defendant tobacco companies to avoid legal responsibility for the harms caused by smoking. Tobacco companies have hired professional historians to try to persuade courts about a longstanding high level of public awareness regarding the risks of tobacco use. To support this argument, they have used archival news clippings and media reports. Two historians were hired by tobacco companies to offer this defence during a recent class action trial in Canada, following which they were required to submit to the court the collection of media materials which had been gathered by history students to assist their testimony. Included in this collection were tobacco advertisements and other news items about tobacco products which the students had inadvertently also collected. Quantifying this collection reveals that even by the tobacco industry's own construct, the information environment surrounding Quebec smokers in the middle 20th century included more prosmoking messages than information about the risks of smoking.

The effect of altered game formats on team performances during soccer practice can be harnessed by coaches to stimulate specific tactical behaviours. The aim of the present study was to analyse the influence of using (i) small goals [SG], (ii) goalkeepers [7G] and (iii) floaters [7GF] on the dispersion, shape and available space of teams during small-sided games (SSGs). Twenty-four male soccer players were distributed into four teams composed of five players, two goalkeepers and two floaters that performed six SSG bouts of 6 min, interspersed with 6 min of passive recovery. Offensive and defensive phases were also analysed separately in order to verify the preservation of basic principles of attacking (teams more stretched to create free space) and defending (teams more compact to tie-up space) during SSGs. The variables used to characterize the collective behaviour were: length [L], width [W], team shape [Sh], and team separateness [TS]. Results revealed that the teams showed different collective behaviours depending on SSG format and a playing phase: a) L and W were higher in attack than in defence in all SSGs; b) team shapes were more elongated in defence in all SSGs except SG; c) the space separating players from their closest opponents (TS) was shorter in 7G; and d) SG and 7GF elicited greater defensive openness due to increased team width. The results suggest that manipulating task constraints, such as goal size, presence or absence of goalkeepers and floaters can be harnessed by coaches to shape distinct team tactical behaviours in SSGs while preserving the basic principles of attacking and defending.

Wilson, Scott D.; Dyson, Rodger W.; Tew, Roy C.; Ibrahim, Mounir B.

2004-01-01

A high efficiency Stirling Radioisotope Generator (SRG) is being developed for possible use in long duration space science missions. NASA s advanced technology goals for next generation Stirling convertors include increasing the Carnot efficiency and percent of Carnot efficiency. To help achieve these goals, a multidimensional Computational Fluid Dynamics (CFD) code is being developed to numerically model unsteady fluid flow and heat transfer phenomena of the oscillating working gas inside Stirling convertors. Simulations of the Stirling convertors for the SRG will help characterize the thermodynamic losses resulting from fluid flow and heat transfer between the working gas and solid walls. The current CFD simulation represents approximated 2-dimensional convertor geometry. The simulation solves the Navier Stokes equations for an ideal helium gas oscillating at low speeds. The current simulation results are discussed.

In-Medium Similarity Renormalization Group Approach to the Nuclear Many-Body Problem

Hergert, Heiko; Bogner, Scott K.; Lietz, Justin G.; Morris, Titus D.; Novario, Samuel J.; Parzuchowski, Nathan M.; Yuan, Fei

We present a pedagogical discussion of Similarity Renormalization Group (SRG) methods, in particular the In-Medium SRG (IMSRG) approach for solving the nuclear many-body problem. These methods use continuous unitary transformations to evolve the nuclear Hamiltonian to a desired shape. The IMSRG, in particular, is used to decouple the ground state from all excitations and solve the many-body Schrödinger equation. We discuss the IMSRG formalism as well as its numerical implementation, and use the method to study the pairing model and infinite neutron matter. We compare our results with those of Coupled cluster theory (Chap. 8), Configuration-Interaction Monte Carlo (Chap. 9), and the Self-Consistent Green's Function approach discussed in Chap. 11 The chapter concludes with an expanded overview of current research directions, and a look ahead at upcoming developments.

Posture monitoring and correction technologies can support prevention and treatment of spinal pain or can help detect and avoid compensatory movements during the neurological rehabilitation of upper extremities, which can be very important to ensure their effectiveness. We describe the design and development of Smart Rehabilitation Garment (SRG) a wearable system designed to support posture correction. The SRG combines a number of inertial measurement units (IMUs), controlled by an Arduino processor. It provides feedback with vibration on the garment, audible alarm signals and visual instruction through a Bluetooth connected smartphone. We discuss the placement of sensing modules, the garment design, the feedback design and the integration of smart textiles and wearable electronics which aimed at achieving wearability and ease of use. We report on the system's accuracy as compared to optical tracker method.

Update on Extended Operation of Stirling Convertors in Thermal Vacuum at NASA Glenn Research Center

2006-01-01

The U.S. Department of Energy (DOE), Lockheed Martin Space Systems (LMSS), Infinia Corporation, and NASA Glenn Research Center (GRC) have been developing a Stirling Radioisotope Generator (SRG) for use as a power system on space science missions. This generator would make use of Stirling cycle energy conversion to achieve higher efficiency than currently used alternatives. A test has been initiated at GRC to demonstrate functionality of Stirling conversion in a thermal vacuum environment over an extended period of time. The test article resembles the configuration of the SRG, but was designed without the requirement of low mass. Throughout the 8700 cumulative hours of operation, modifications to the supporting hardware were required to attain the desired operating conditions. These modifications, the status of testing, and the data recorded will be discussed in this paper.

Fitness to Stand Trial is a critical concept in the adjudication of justice-involved persons. A retrospective study was conducted to examine criminal defendants' specific psychiatric symptoms and those symptoms' associations with expert opinions on Competence to Stand Trial. One hundred charts were reviewed: 50 Cases (opined as Not Fit) were compared against 50 Controls (opined as Fit) with respect to ratings on the Brief Psychiatric Rating Scale (BPRS). A significance level of 0.001 was selected a priori. Statistically significant differences were found in seven of the eighteen BPRS symptom constructs (with the highest differences in Conceptual Disorganization and Unusual Thought Content) and two of the four BPRS higher-order syndrome factors (Thinking Disorder and Hostile-Suspiciousness). Consistent with previous reports, psychotic symptoms are found in this study to be inversely associated with Fitness. Validity, reliability, and limitations of this study, as well as directions for future research, are discussed herein. © 2014 American Academy of Forensic Sciences.

Rock glaciers are widespread permafrost landforms in Austria. Various rock glacier inventories list more than 4500 rock glaciers in the country; some 30-40% of them are intact. Relict (permafrost free) and pseudo-relict rock glaciers (sporadic and isolated permafrost particularly near the root zone) prevail in number. Rock glaciers are commonly formed over a period of several ka. Dating such landforms helps to understand palaeoclimatic conditions. In this study three rock glaciers consisting of gneiss were dated applying the Schmidt-hammer exposure-age dating (SHD) method. The rock glaciers are located at three neighbouring cirques in the Seckauer Tauern Range named Reichart Rock Glacier (RRG, area 1.26 km², length 1800 m, elevation range 1520-1940 m a.s.l.), Schöneben Rock Glacier (SRG, 0.11 km², 750 m, 1715-1905 m a.s.l.), and Dürrtal Rock Glacier (DRG, 0.08 km², 850 m, 1750-1980 m a.s.l.). RRG is one of the largest rock glaciers in Austria. All three landforms are influenced by lenses of permafrost at present (as indicated by ERT). During the LGM the Seckauer Tauern were covered by valley glaciers and deglaciation occurred presumably already early in the Alpine Lateglacial period. An analogue N-type Schmidt-hammer (proceq) was used for measuring the surface strength of stable blocks at the rock glacier surface by recording a rebound value (R-value) of a spring-loaded bolt. The R-value gives a relative measure of the surface hardness and hence time since exposure to weathering. Eight (RRG) or six (SRG, DRG) Schmidt-hammer measurement sites (with 50-100 individual readings) aligned along longitudinal transects (=former central flow line) between a talus slope (with relatively fresh boulders) in the root zone and the frontal ridge were measured. Mean R-value differences of 30.5 at RRG, 25.1 at SRG, and 20.7 at DRG were revealed along the three transects. The differences between the lowest and the highest R-value at the rock glaciers itself were 19.0 at RRG, 15

This study is an audit of the Somerset Court Advice and Assessment Service (CAAS) throughout its first year of implementation. It reports that the service successfully met the six desired objectives as set out in its Service Level Agreement. Further to this, it reports that the use of National Health Service electronic patient records within a court setting facilitated the provision of apposite and timely information to the court. Specific findings were that deliberate self-harm/suicidal ideation and mood disorders were the primary reasons for a person requiring CAAS involvement. Violence against the person, breach of orders and theft were the most prevalent categories of offending within this referred group. The prevalence of previous psychiatric history was significantly higher than found in comparable audits. It is likely that this is due to the efficacy of proactive and in vivo utilization of electronic patient records. Conclusions include the need to work in partnership with drug and alcohol agencies and the importance of recognizing that these services have significant clinical benefits for defendants with mental health problems, and the court system in terms of financial savings. We suggest ongoing audit is necessary to guide the development of other schemes in this pioneering service area.

The present studies were carried out with the aims to determine the cDNA sequence for cyclooxygenase (COX) in an elasmobranch species and to study its role in regulation of chloride secretion in the perfused shark rectal gland (SRG). With the use of long primers (43 bp) derived from regions of homology between zebrafish and rainbow trout COX-2 genes, a 600-bp product was amplified from SRG and was found to be almost equally homologous to mammalian COX-1 and COX-2 (65%). The full-length cDNA sequence was obtained by 5'-RACE and by analyzing an EST clone generated by the EST Project of the Mt. Desert Island Biological Laboratory Marine DNA Sequencing Center. The longest open reading frame encodes a 593-amino acid protein that has 68 and 64% homology to mammalian COX-1 and COX-2, respectively. The gene and its protein product is designated as shark COX (sCOX). The key residues in the active site (Try(385), His(388), and Ser(530)) are conserved between the shark and mammalian COX. sCOX contains Val(523) that has been shown to be a key residue determining the sensitivity to COX-2-specific inhibitors including NS-398. The mRNA of sCOX, detected by RT-PCR, was found in all tissues tested, including rectal gland, kidney, spleen, gill, liver, brain, and heart, but not in fin. In the perfused SRG, vasoactive intestinal peptide (VIP) at 5 nM induced rapid and marked Cl(-) secretion (basal: <250 microeq x h(-1) x g(-1); peak response: 3,108 +/- 479 microeq x h(-1) x g(-1)). In the presence of 50 microM NS-398, both the peak response (2,131 +/- 307 microeq x h(-1) x g(-1)) and the sustained response to VIP were significantly reduced. When NS-398 was removed, there was a prompt recovery of chloride secretion to control values. In conclusion, we have cloned the first COX in an elasmobranch species (sCOX) and shown that sCOX inhibition suppresses VIP-stimulated chloride secretion in the perfused SRG.

Ethical Frameworks in Public Health Decision-Making: Defending a Value-Based and Pluralist Approach.

PubMed

Grill, Kalle; Dawson, Angus

2017-12-01

A number of ethical frameworks have been proposed to support decision-making in public health and the evaluation of public health policy and practice. This is encouraging, since ethical considerations are of paramount importance in health policy. However, these frameworks have various deficiencies, in part because they incorporate substantial ethical positions. In this article, we discuss and criticise a framework developed by James Childress and Ruth Bernheim, which we consider to be the state of the art in the field. Their framework distinguishes aims, such as the promotion of public health, from constraints on the pursuit of those aims, such as the requirement to avoid limitations to liberty, or the requirement to be impartial. We show how this structure creates both theoretical and practical problems. We then go on to present and defend a more practical framework, one that is neutral in avoiding precommitment to particular values and how they ought to be weighted. We believe ethics is at the very heart of such weightings and our framework is developed to reflect this belief. It is therefore both pluralist and value-based. We compare our new framework to Childress and Bernheim's and outline its advantages. It is justified by its impetus to consider a wide range of alternatives and its tendency to direct decisions towards the best alternatives, as well as by the information provided by the ranking of alternatives and transparent explication of the judgements that motivate this ranking. The new framework presented should be useful to decision-makers in public health, as well as being a means to stimulate further reflection on the role of ethics in public health.

The U.S. Department of Energy (DOE), in conjunction with NASA John H. Glenn Research Center and Stirling Technology Company, are currently developing a Stirling convertor for a Stirling Radioisotope Generator (SRG). NASA Headquarters and DOE have identified the SRG for potential use as an advanced spacecraft power system for future NASA deep-space and Mars surface missions. Low-level dynamic base-shake tests were conducted on a dynamic simulation of the structural mount for a pair of Operating Stirling Convertors. These tests were conducted at NASA Glenn Research Center's Structural Dynamics Laboratory as part of the development of this technology. The purpose of these tests was to identify the changes in transmissibility and the effect on structural dynamic response on a pair of operating Stirling Technology Demonstration Convertors (TDCs). This paper addresses the base-shake test, setup, procedure and results conducted on the Stirling TDC mount simulator in April 2001. .

The NASA Glenn Research Center (GRC) is conducting in-house research on rare-earth permanent magnets and linear alternators to assist in developing free-piston Stirling convertors for radioisotope space power systems and for developing advanced linear alternator technology. This research continues at GRC, but, with the exception of Advanced Stirling Radioisotope Generator references, the work presented in this paper was conducted in 2005. A special arc-magnet characterization fixture was designed and built to measure the M-H characteristics of the magnets used in Technology Demonstration Convertors developed under the 110-W Stirling Radioisotope Generator (SRG110) project. This fixture was used to measure these characteristics of the arc magnets and to predict alternator demagnetization temperatures in the SRG110 application. Demagnetization tests using the TDC alternator on the Alternator Test Rig were conducted for two different magnet grades: Sumitomo Neomax 44AH and 42AH. The purpose of these tests was to determine the demagnetization temperatures of the magnets for the alternator under nominal loads. Measurements made during the tests included the linear alternator terminal voltage, current, average power, magnet temperatures, and stator temperatures. The results of these tests were found to be in good agreement with predictions. Alternator demagnetization temperatures in the Advanced Stirling Convertor (ASC-developed under the Advanced Stirling Radioisotope Generator project) were predicted as well because the prediction method had been validated through the SRG110 alternator tests. These predictions led to a specification for maximum temperatures of the ASC pressure vessel.

Defending a coherent autobiography: when past events appear incoherent, mortality salience prompts compensatory bolstering of the past's significance and the future's orderliness.

PubMed

Landau, Mark J; Greenberg, Jeff; Sullivan, Daniel

Drawing on terror management theory, we propose that maintaining a coherent autobiography protects the individual from mortality concerns by imbuing experience over time with significance and order. Two studies test whether mortality salience combined with a threat to autobiographical coherence (induced by an alphabetical organization of past events) prompts compensatory bolstering of the significance and orderliness of temporal experience. In Study 1, whereas exclusion-primed participants led to organize past events alphabetically perceived their past as less significant, mortality salient participants showed a compensatory boost in perceptions of their past's significance. In Study 2, mortality salience and an alphabetic event organization led participants high in personal need for structure to parse their future into clearly defined temporal intervals. This research is the first to experimentally assess the role of existential concerns in people's motivation to defend the significance and structure of their temporal experience against threats to autobiographical coherence.

There is a small, but growing, body of research investigating peer-victimisation between preschoolers, an age which has been identified as being important both theoretically and practically for the development of interventions. This study compares aggressive and defending behaviour and victim status of preschoolers in three European countries; England, Spain and Italy. The results provide further confirmation that some children behave aggressively towards their peers during preschool in each of the countries studied. There are similarities between preschool children involved in peer-victimisation in the three countries in terms of the roles taken, sex differences and the types of aggressive behaviours used and experienced by the children. There were differences in the profiles of children identified as taking the roles by teachers and peers. Overall, it was found that those children identified by peers or teachers as being aggressive were more likely to be male, rated as physically strong and more likely to be rejected by classmates. Also, in general, the targets of peer-victimisation differed depending on the reporter. Peer-nominated victims were not identifiable in terms of gender, popularity or physical strength. Teacher-nominated victims were more likely to be socially rejected and physically weak. There are several subtle differences between the countries which deserve further investigation. The findings are discussed in relation to furthering our understanding of the development of peer-victimisation in preschools and the need for interventions which address this phenomenon.

We investigated the internal structure comparability of Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) scores derived from the MMPI-2 and MMPI-2-RF booklets in a sample of 320 criminal defendants (229 males and 54 females). After exclusion of invalid protocols, the final sample consisted of 96 defendants who were administered the MMPI-2-RF booklet and 83 who completed the MMPI-2. No statistically significant differences in MMPI-2-RF invalidity rates were observed between the two forms. Individuals in the final sample who completed the MMPI-2-RF did not statistically differ on demographics or referral question from those who were administered the MMPI-2 booklet. Independent t tests showed no statistically significant differences between MMPI-2-RF scores generated with the MMPI-2 and MMPI-2-RF booklets on the test's substantive scales. Statistically significant small differences were observed on the revised Variable Response Inconsistency (VRIN-r) and True Response Inconsistency (TRIN-r) scales. Cronbach's alpha and standard errors of measurement were approximately equal between the booklets for all MMPI-2-RF scales. Finally, MMPI-2-RF intercorrelations produced from the two forms yielded mostly small and a few medium differences, indicating that discriminant validity and test structure are maintained. Overall, our findings reflect the internal structure comparability of MMPI-2-RF scale scores generated from MMPI-2 and MMPI-2-RF booklets. Implications of these results and limitations of these findings are discussed. © The Author(s) 2014.

2006-01-01

A 110 watt Stirling Radioisotope Generator (SRG110) is being developed for potential use on future NASA exploration missions. The development effort is being performed by Lockheed Martin under contract to the Department of Energy (DOE). Infinia, Corp. supplies the free-piston Stirling power convertors, and NASA Glenn Research Center (GRC) provides support to the effort in a range of technologies. This generator features higher efficiency and specific power compared to alternatives. One potential application for the generator would entail significant cruise time in the vacuum of deep space. A test has been initiated at GRC to demonstrate functionality of the Stirling convertors in a thermal vacuum environment. The test article resembles the configuration of the SRG110, however the requirement for low mass was not considered. This test demonstrates the operation of the Stirling convertors in the thermal vacuum environment, simulating deep space, over an extended period of operation. The status of the test as well as the data gathered will be presented in this paper.

Potential mission use includes providing spacecraft onboard electric power for deep space missions and power for unmanned Mars rovers. GRC is conducting an in-house supporting technology project to assist in SRG110 development. One-, three-, and six-month heater head structural benchmark tests have been completed in support of a heater head life assessment. Testing is underway to evaluate the key epoxy bond of the permanent magnets to the linear alternator stator lamination stack. GRC has completed over 10,000 hours of extended duration testing of the Stirling convertors for the SRG110, and a three-year test of two Stirling convertors in a thermal vacuum environment will be starting shortly. GRC is also developing advanced technology for Stirling convertors, aimed at substantially improving the specific power and efficiency of the convertor and the overall generator. Sunpower, Inc. has begun the development of a lightweight Stirling convertor, under a NASA Research Announcement (NRA) award, that has the potential to double the system specific power to about 8 W(sub e) per kilogram. GRC has performed random vibration testing of a lowerpower version of this convertor to evaluate robustness for surviving launch vibrations. STC has also completed the initial design of a lightweight convertor. Status of the development of a multi-dimensional computational fluid dynamics code and high-temperature materials work on advanced superalloys, refractory metal alloys, and ceramics are also discussed.

The Department of Energy, Lockheed Martin (LM), Stirling Technology Company, and NASA Glenn Research Center (GRC) are developing a high-efficiency Stirling Radioisotope Generator (SRG) for potential NASA Space Science missions. The SRG is being developed for multimission use, including providing spacecraft onboard electric power for NASA deep space missions and power for unmanned Mars rovers. NASA GRC is conducting an in- house supporting technology project to assist in developing the Stirling convertor for space qualification and mission implementation. Preparations are underway for a thermalhacuum system demonstration and unattended operation during endurance testing of the 55-We Technology Demonstration Convertors. Heater head life assessment efforts continue, including verification of the heater head brazing and heat treatment schedules and evaluation of any potential regenerator oxidation. Long-term magnet aging tests are continuing to characterize any possible aging in the strength or demagnetization resistance of the permanent magnets used in the linear alternator. Testing of the magnet/lamination epoxy bond for performance and lifetime characteristics is now underway. These efforts are expected to provide key inputs as the system integrator, LM, begins system development of the SRG. GRC is also developing advanced technology for Stirling convertors. Cleveland State University (CSU) is progressing toward a multi-dimensional Stirling computational fluid dynamics code, capable of modeling complete convertors. Validation efforts at both CSU and the University of Minnesota are complementing the code development. New efforts have been started this year on a lightweight convertor, advanced controllers, high-temperature materials, and an end-to-end system dynamics model. Performance and mass improvement goals have been established for second- and third-generation Stirling radioisotope power systems.

Pseudomorphic Al0.22Ga0.78As/In0.16Ga0.84As/Al0.22Ga0.78As double heterojunction high electron mobility transistors (DH-HEMTs) fabricated with different gate-formation structures of a single-recess gate (SRG), a double-recess gate (DRG) and a field-plate gate (FPG) were comparatively investigated. FPG devices show the best breakdown characteristics among these devices due to great reduction in the peak electric field between the drain and gate electrodes. The measured gate-drain breakdown voltages defined at a 1 mA mm-1 reverse gate-drain current density were -15.3, -19.1 and -26.0 V for SRG, DRG and FPG devices, respectively. No significant differences in their room-temperature common-source current-voltage characteristics were observed. However, FPG devices exhibit threshold voltages being the least sensitive to temperature. Threshold voltages as a function of temperature indicate a threshold-voltage variation as low as -0.97 mV K-1 for FPG devices. According to the 2.4 GHz load-pull power measurement at VDS = 3.0 V and VGS = -0.5 V, the saturated output power (POUT), power gain (GP) and maximum power-added efficiency (PAE) were 10.3 dBm/13.2 dB/36.6%, 11.2 dBm/13.1 dB/39.7% and 13.06 dBm/12.8 dB/47.3%, respectively, for SRG, DRG and FPG devices with a pi-gate in class AB operation. When the FPG device is biased at a VDS of 10 V, the saturated power density is more than 600 mW mm-1.

Formation of surface relief grating in polymers with pendant azobenzene chromophores as studied by AFM/UFM

We studied peculiarities of the structural reconstruction within holographically recorded gratings on the surface of several different amorphous azobenzene-containing polymers. Under illumination with a light interference pattern, two processes take place in this type of polymer. The first process is the light-induced orientation of azobenzene units perpendicular to the polarization plane of the incident light. The second one is a transfer of macromolecules along the grating vector (i.e. perpendicular to the grating lines). These two processes result in the creation of a volume orientation grating (alternating regions of different direction or degree of molecular orientation) and a surface relief grating (SRG)—i.e. modulation of film thickness. One can assume that both orientation of molecules and their movement might change the local mechanical properties of the material. Therefore, formation of the SRG is expected to result also in modulation of the local stiffness of the polymer film. To reveal and investigate these stiffness changes within the grating, spin-coated polymer films were prepared and the gratings were recorded on them in two different ways: with an orthogonal circular or orthogonal linear polarization of two recording light beams. A combination of atomic force microscopy (AFM) and ultrasonic force microscopy (UFM) techniques was applied for SRG development monitoring. We demonstrate that formation of the phase gratings depends on the chemical structure of polymers being used, polymer film thickness, and recording parameters, with the height of grating structures (depth of modulation) increasing with both the exposure time and the film thickness. UFM images suggest that the slopes of the topographic peaks in the phase gratings exhibit an increased stiffness with respect to the grating depressions.

Eating chemically defended prey: alkaloid metabolism in an invasive ladybird predator of other ladybirds (Coleoptera: Coccinellidae).

PubMed

Sloggett, J J; Davis, A J

2010-01-15

By comparison with studies of herbivore physiological adaptation to plant allelochemicals, work on predator physiological adaptation to potentially toxic prey has been very limited. Such studies are important in understanding how evolution could shape predator diets. An interesting question is the specificity of predator adaptation to prey allelochemicals, given that many predators consume diverse prey with different chemical defences. The ladybird Harmonia axyridis, an invasive species in America, Europe and Africa, is considered a significant predatory threat to native invertebrates, particularly other aphid-eating ladybirds of which it is a strong intraguild predator. Although ladybirds possess species-specific alkaloid defences, H. axyridis exhibits high tolerance for allospecific ladybird prey alkaloids. Nonetheless, it performs poorly on species with novel alkaloids not commonly occurring within its natural range. We examined alkaloid fate in H. axyridis larvae after consumption of two other ladybird species, one containing an alkaloid historically occurring within the predator's native range (isopropyleine) and one containing a novel alkaloid that does not (adaline). Our results indicate that H. axyridis rapidly chemically modifies the alkaloid to which it has been historically exposed to render it less harmful: this probably occurs outside of the gut. The novel, more toxic alkaloid persists in the body unchanged for longer. Our results suggest metabolic alkaloid specialisation, in spite of the diversity of chemically defended prey that the predator consumes. Physiological adaptations appear to have made H. axyridis a successful predator of other ladybirds; however, limitations are imposed by its physiology when it eats prey with novel alkaloids.

A reassessment of the function of floral nectar in Croton suberosus (Euphorbiaceae): A reward for plant defenders and pollinators.

PubMed

Narbona, Eduardo; Dirzo, Rodolfo

2010-04-01

Typically, plant-pollinator interactions are recognized as mutualistic relationships. Flower visitors, however, can potentially play multiple roles. The floral nectar in Croton suberosus has been proposed to operate as a reward for predators, especially the wasp Polistes instabilis (Vespidae), which kills herbivorous insects, while the plant has been thought to be mainly wind-pollinated. In this study, we reassessed the pollination mode of C. suberosus and the possible role of its flower visitors. Pollinator exclusion experiments demonstrated that C. suberosus should be considered a strictly entomophilous species. Inflorescences of C. suberosus were visited by a diverse entomofauna involving 28 taxa belonging to six orders; however, wasps and bees were the only visitors that carried C. suberosus pollen. The visitation rate of wasps was approximately four times that of bees. This observation, combined with the fact that the small size of bees makes effective contact of their bodies with the stigma difficult, strongly suggests that large wasps are responsible for most of the effective pollination of C. suberosus. Among the wasp visitors, P. instabilis seems to be one of the most important. These findings expose an unusual plant-insect interaction, in which the plant provides nectar and wasps pollinate and defend the plant.

Gastrointestinal toxicity of nonsteroidal anti-inflammatory drugs (NSAIDs) has been perplexing most clinicians and users of NSAIDs. Rebamipide is increasingly advocated as a candidate option for the prevention of NSAIDs induced gastrointestinal mucosal injury. To assess the efficacy and the safety of rebamipide for the prevention and treatment of NSAID-induced gastroenteropathy. PubMed, Embase, Web of Science, Google Scholar, the Cochrane Library, Japan Science and Technology Information Aggregator, and China Biology Medicine Disc were searched up to December 2011. Randomized controlled trials (RCTs) recruiting subjects with co-prescriptions of NSAIDs and rebamipide were eligible. Efficacy and safety of rebamipide were reevaluated, and dichotomous data were pooled to obtain relative risk (RR) with a 95 % confidence interval. Heterogeneity and publication bias were assessed by the inconsistency index statistic and funnel plot analysis, respectively. The search identified 338 citations, and 15 RCTs including 965 individuals were eligible. In general, rebamipide acted better than placebo against short-term NSAID-induced gastroduodenal injury. Separate studies showed rebamipide was equal to or not superior to traditional strategies (including PPIs, H2RA and misoprostol treatment). Especially, rebamipide showed a beneficial effect against the small bowel damage (total RR = 2.70, 95 % confidence interval = 1.02-7.16, P = 0.045) when compared with placebo group. The average incidence of adverse events was about 36.1 % (0-70.0 %) but no serious event was recorded. Current evidences show rebamipide is effective and safe for defending against NSAID-induced gastroduodenal and lower-gastrointestinal injuries. However, more well-designed trials should be conducted to fully confirm the practical value of rebamipide.

The in vitro perfused rectal gland of the dogfish shark (Squalus acanthias) and filter-grown monolayers of primary cultures of shark rectal gland (SRG) epithelial cells were used to analyze the signal transduction pathway by which C-type natriuretic peptide (CNP) stimulates chloride secretion. CNP binds to natriuretic receptors in the basolateral membrane, elevates cellular cGMP, and opens cystic fibrosis transmembrane conductance regulator (CFTR) chloride channels in the apical membrane. CNP-provoked chloride secretion was completely inhibitable by the nonspecific protein kinase inhibitor staurosporine and the PKA inhibitor H89 but insensitive to H8, an inhibitor of type I and II isoforms of cGMP-dependent protein kinase (cGKI and cGKII). CNP-induced secretion could not be mimicked by nonhydrolyzable cGMP analogs added alone or in combination with the protein kinase C activator phorbolester, arguing against a role for cGK or for cGMP-induced PKC signaling. We failed to detect a dogfish ortholog of cGKII by molecular cloning and affinity chromatography. However, inhibitors of the cGMP-inhibitable isoform of phosphodiesterase (PDE3) including milrinone, amrinone, and cilostamide but not inhibitors of other PDE isoenzymes mimicked the effect of CNP on chloride secretion in perfused glands and monolayers. CNP raised cGMP and cAMP levels in the SRG epithelial cells. This rise in cAMP as well as the CNP and amrinone-provoked chloride secretion, but not the rise in cGMP, was almost completely blocked by the Gαi-coupled adenylyl cyclase inhibitor somatostatin, arguing against a role for cGMP cross-activation of PKA in CNP action. These data provide molecular, functional, and pharmacological evidence for a CNP/cGMP/PDE3/cAMP/PKA signaling cascade coupled to CFTR in the SRG. PMID:24259420

Tajer Mohammad Ghazvini, P.; Ghorbanzadeh Mashkani, S.; Ghafourian, H.

Attempt was made to isolate bacterial strains capable of removing Sr biologically. In this study we collected ten different water samples from naturally radioactive spring Neydasht in Iran and bacterial strains samples isolated. Initial screening of a total of 50 bacterial isolates resulted in selection of one strain. The strain showed maximum adsorption capacity with 55 mg Sr/g dry wt. It was tentatively identified as Bacillus sp. according to morphological and biochemical properties and called strain GTG-83. Studies indicated that Bacillus sp. GTG-83 was able to grow aerobically in the presence of 50 mM SrCl{sub 2} but showed severe growthmore » inhibition at levels above that concentration. The bio-sorption capacity of Bacillus sp. GTG-83 strongly depends on solution pH, and the maximum Sr sorption capacity of Bacillus sp. GTG-83 were obtained at pH 10 independent of the absence or the presence of increasing concentrations of salt (MgCl{sub 2}). Sr-salt bio-sorption studies were also performed at this pH values. Equilibrium uptakes of Sr increased with increasing Sr concentrations up to 250 mg/l for Bacillus sp. GTG-83. Maximum bio-sorption of Sr was obtained at temperatures in the range of 30-35 deg. C. Bacillus sp. GTG-83 bio-sorbed 97 mg Sr/g dry wt at 100 mg/l initial Sr concentration without salt medium (MgCl{sub 2}). When salt concentration (MgCl{sub 2}) increased to 15% (w/v), these values dropped to 23.6 mg Sr/g dry wt at the same conditions. Uptake of Sr within 5 min of incubation was relatively rapid and the absorption continued slowly thereafter. (authors)« less

Design and Fabrication of a Stirling Thermal Vacuum Test

Oriti, Salvatore M.; Schreiber, Jeffrey G.

2004-01-01

A Stirling Radioisotope Generator (SRG110) is being developed for potential use on future NASA space science missions. The development effort is being conducted by Lockheed Martin under contract to the Department of Energy (DOE). The Stirling Technology Company supplies the free-piston Stirling power convertors, and NASA Glenn Research Center (GRC) provides support to the effort in a range of technologies. This generator features higher efficiency and specific power compared to the currently used alternatives. One potential application for the generator would entail significant cruise time in the vacuum of deep space. A test has been conceived at GRC to demonstrate functionality of the Stirling convertors in a thermal vacuum environment. The test article resembles the configuration of the SRG, however the requirement for low mass was not considered. This test will demonstrate the operation of the Stirling convertors in the thermal vacuum environment, simulating deep space, over an extended period of operation. The analysis, design, and fabrication of the test article will be described in this paper.

Endophytes in plants may be co-producer of the bioactive compounds of their hosts. We conducted a study to bioprospect for saponin-producing endophytic fungi from Panax notoginseng and evaluate the antimicrobial activity of saponins. Two novel fungal endophytes, Fusarium sp. PN8 and Aspergillus sp. PN17, were isolated from traditional Chinese medicinal herb P. notoginseng. After eight days of fermentation, the total saponins produced in the culture broth of PN8 and PN17 were 1.061 and 0.583 mg mL -1 , respectively. The saponin extracts exhibited moderate to high (inhibition zone diameter 15.7-28.4 mm, MIC 1.6-12.5 mg mL -1 ) antimicrobial activity against pathogens tested. Further analysis showed that triterpenoid saponins produced by Fusarium PN8 were Rb 1 , Rd and 20(S)-Rg 3 , while Aspergillus PN17 had the ability to synthesise ginsenoside Re, Rd and 20(S)-Rg 3 . The isolated endophytes may be used as potential sources for microbial production of plant secondary metabolites and for antimicrobial agents.

TUBITAK National Observatory supports the GAIA alerts with observations using three telescopes (RTT150, T100, T60) at the site with a limited time quota. We have observed 10 variable stars among GAIA sources discovered in the years 2014-2016 that may be candidate Cataclysmic Variables (CVs). Our TUG observations at this stage involve photometry and spectroscopy to aid the identification of these sources. The first preliminary result of our observations of Gaia14aat among them showed a dwarf nova outburst with an amplitude of 2.69 mag. We aim to construct a GAIA astrophysics group to study CVs along with supported studies using the SRG (Spectrum Roentgen Gamma astrophysical observatory) after the year of 2016. These observations will basically involve spectroscopy, narrow-band CCD imaging and photometry using several filters to aid the identification of these sources. RTT150 observations with very narrow filters (like H-alpha, SII, OIII with band width of range of 2 to 5 nm) will reveal whether shell around the SRG sources to aid identification novae among them.

We previously demonstrated the relationship between sidestepping performance and the preparatory state of ground reaction forces (GRFs). The present study investigated the effect of the preparatory state of GRFs on defensive performance in 1-on-1 subphase of basketball. Ten basketball players participated in 1-on-1 dribble game of basketball. The outcomes (penetrating and guarding) and the preparatory state of GRFs (non-weighted and weighted states, i.e. vertical GRFs below and above 120% of body weight, respectively) were assessed by separating the phases. In the non-weighted state and the weighted state to determine the outcome, the probability of successful guarding was 78.8% and 29.6%, respectively. The non-weighted state prevented delay of the defensive step in the determination phase. Both the non-weighted and weighted states, immediately before the determination phase, were likely to change to the weighted state in the determination phase; during this time, the defender's preparatory state would be destabilised, presumably by the dribbler's movement. These results revealed that the preparatory GRFs before the defensive step help to explain the outcome of the 1-on-1 subphase, and suggest a better way to prevent delaying initiation of the defensive step and thereby to guard more effectively against a dribbler.

Serine Protease Inhibitors Specifically Defend Solanum nigrum against Generalist Herbivores but Do Not Influence Plant Growth and Development[C][W

Solanaceaeous taxa produce diverse peptide serine proteinase inhibitors (SPIs), known antidigestive defenses that might also control endogenous plant proteases. If and how a plant coordinates and combines its different SPIs for the defense against herbivores and if these SPIs simultaneously serve developmental functions is unknown. We examine Solanum nigrum’s SPI profile, comprising four different active inhibitors, of which the most abundant proved to be novel, to understand their functional specialization in an ecological context. Transcript and activity characterization revealed tissue-specific and insect-elicited accumulation patterns. Stable and transient gene silencing of all four SPIs revealed different specificities for target proteinases: the novel SPI2c displayed high specificity for trypsin and chymotrypsin, while two other SPI2 homologs were highly active against subtilisin. In field and lab experiments, we found all four SPIs to display herbivore- and gene-specific defensive properties, with dissimilar effects on closely related species. However, we did not observe any clear developmental phenotype in SPI-silenced plants, suggesting that SPIs do not play a major role in regulating endogenous proteases under the conditions studied. In summary, specific single SPIs or their combinations defend S. nigrum against generalist herbivores, while the defense against herbivores specialized on SPI-rich diets requires other unknown defense mechanisms.

"Too stubborn to ever be governed by enforced insanity": Some therapeutic jurisprudence dilemmas in the representation of criminal defendants in incompetency and insanity cases.

PubMed

Perlin, Michael L

2010-01-01

Little attention has been paid to the importance of the relationship between therapeutic jurisprudence (TJ) and the role of criminal defense lawyers in insanity and incompetency-to-stand-trial (IST) cases. That inattention is especially noteworthy in light of the dismal track record of counsel providing services to defendants who are part of this cohort of incompetency-status-raisers and insanity-defense-pleaders. On one hand, this lack of attention is a surprise as TJ scholars have, in recent years, turned their attention to virtually every other aspect of the legal system. On the other hand, it is not a surprise, given the omnipresence of sanism, an irrational prejudice of the same quality and character of other irrational prejudices that cause (and are reflected in) prevailing social attitudes of racism, sexism, homophobia, and ethnic bigotry, that infects both our jurisprudence and our lawyering practices. Sanism is largely invisible and largely socially acceptable, and is based predominantly upon stereotype, myth, superstition, and deindividualization. It is sustained and perpetuated by our use of alleged "ordinary common sense" (OCS) and heuristic reasoning in an unconscious response to events both in everyday life and in the legal process. This paper examines the literature that seeks to apply TJ principles to the criminal law process in general, drawing mostly on the work of Professor David Wexler. It considers why the lack of attention that I have referred to already is surprising (given TJ's mandate and the fact that many TJ issues are inevitably raised in any insanity or IST case). The paper then considers why this lack of attention is not surprising, given the omnipresence of sanism. It will consider some of the actual counseling issues that might arise in these contexts, and offer some suggestions to lawyers representing clients in cases in which mental status issues may be raised. The paper concludes that we must rigorously apply therapeutic

Candidate Materials Evaluated for a High-Temperature Stirling Convertor Heater Head

Bowman, Randy R.; Ritzert, Frank J.

2005-01-01

The Department of Energy and NASA have identified Stirling Radioisotope Generators (SRGs) as a candidate power system for use on long-duration, deep-space science missions and Mars rovers. One of the developments planned for an upgraded version of the current SRG design is to achieve higher efficiency by increasing the overall operating temperature of the system. Currently, the SRG operates with a heater head temperature of 650 C and is fabricated from the nickel-base superalloy 718. The current operating temperature is at the limit of alloy 718 s capability, and any planned increase in temperature will be contingent on identifying a more capable material from which to fabricate the heater head. To this end, personnel at the NASA Glenn Research Center are evaluating advanced materials for a high-temperature heater head to allow a higher convertor temperature ratio and, thus, increase the system efficiency. A generic list of properties that were used to screen the candidate materials follows: (1) creep, (2) fabricability, (3) helium gas containment, (4) long-term stability and compatibility, (5) ability to form a hermetical closeout seal, and (6) ductility and toughness.

2017-11-01

The paper presents the results of a series of in-situ tests carried out on two masonry arches, one unreinforced and the other reinforced with SRG (Steel Reinforced Grout). The arches are built adopting a peculiar construction technique using common Italian bricks with dimensions 250 × 120 × 55 mm3 and 10 mm thick mortar joints. One of the two arches has been reinforced with an SRG material constituted by an inox grid embedded into a layer of lime mortar, whereas the second one is maintained unreinforced for comparison purposes. The experimental set-up is designed to apply an eccentric vertical load placed at ¼ of the span in a series of loading and unloading cycles up to the failure. The numerical analyses have been performed using a sophisticated heterogeneous micro-modeling technique, where bricks, mortar joints and the strengthening have been modeled separately. Finally, the numerical outcomes have been comparatively assessed with respect to the experimental results and the crack patterns obtained at the end of the tests, showing a satisfactory agreement in terms of the global behavior of the arches and their collapse mechanisms.

The National Aeronautics and Space Administration (NASA) has typically used Radioisotope Thermoelectric Generators (RTG) as their source of electric power for deep space missions. A more efficient and potentially more cost effective alternative to the RTG, the high efficiency 110 watt Stirling Radioisotope Generator 110 (SRG110) is being developed by the Department of Energy (DOE), Lockheed Martin (LM), Stirling Technology Company (STC) and NASA Glenn Research Center (GRC). The SRG110 consists of two Stirling convertors (Stirling Engine and Linear Alternator) in a dual-opposed configuration, and two General Purpose Heat Source (GPHS) modules. Although Stirling convertors have been successfully operated as a power source for the utility grid and as a stand-alone portable generator, demonstration of the technology required to interconnect two Stirling convertors for a spacecraft power system has not been attempted. NASA GRC is developing a Power System Test Bed (PSTB) to evaluate the performance of a Stirling convertor in an integrated electrical power system application. This paper will describe the status of the PSTB and on-going activities pertaining to the PSTB in the NASA Thermal-Energy Conversion Branch of the Power and On-Board Propulsion Technology Division.

Reliability Issues in Stirling Radioisotope Power Systems

2005-01-01

Stirling power conversion is a potential candidate for use in a Radioisotope Power System (RPS) for space science missions because it offers a multifold increase in the conversion efficiency of heat to electric power and reduced requirement of radioactive material. Reliability of an RPS that utilizes Stirling power conversion technology is important in order to ascertain long term successful performance. Owing to long life time requirement (14 years), it is difficult to perform long-term tests that encompass all the uncertainties involved in the design variables of components and subsystems comprising the RPS. The requirement for uninterrupted performance reliability and related issues are discussed, and some of the critical areas of concern are identified. An overview of the current on-going efforts to understand component life, design variables at the component and system levels, and related sources and nature of uncertainties are also discussed. Current status of the 110 watt Stirling Radioisotope Generator (SRG110) reliability efforts is described. Additionally, an approach showing the use of past experience on other successfully used power systems to develop a reliability plan for the SRG110 design is outlined.

A bilateral comparison of absolute gas pressure measurements from 3 × 10-9 Pa to 9 × 10-4 Pa was performed between the National Metrology Institute of Japan (NMIJ) and Physikalisch-Technische Bundesanstalt (PTB). It is a pilot study CCM.P-P1 for the next international comparison in this pressure range to test the stability of ultrahigh vacuum gauges (UHV gauges) as transfer standards. Two spinning rotor gauges (SRGs), an axial-symmetric transmission gauge (ATG), and an extractor gauge (EXG) were used as transfer standards. The calibration ratio of one SRG was sufficiently stable, but the other was not. This result indicates that improvements in the transport mechanism for SRG are needed. The two ionization gauges ATG and EXG, on the other hand, were sufficiently stable. Provisional equivalence of the pressures realized by the primary standards at NMIJ and PTB was found. Main text.

2005-01-01

The Vision for Space Exploration has a goal of sending crewed missions to the lunar surface as early as 2015 and no later than 2020. The use of nuclear power sources could aid in assisting crews in exploring the surface and performing In-Situ Resource Utilization (ISRU) activities. Radioisotope Power Systems (RPS) provide constant sources of electrical power and thermal energy for space applications. RPSs were carried on six of the crewed Apollo missions to power surface science packages, five of which still remain on the lunar surface. Future RPS designs may be able to play a more active role in supporting a long-term human presence. Due to its lower thermal and radiation output, the planned Stirling Radioisotope Generator (SRG) appears particularly attractive for manned applications. The MCNPX particle transport code has been used to model the current SRG design to assess its use in proximity with astronauts operating on the surface. Concepts of mobility and ISRU infrastructure were modeled using MCNPX to analyze the impact of RPSs on crewed mobility systems. Strategies for lowering the radiation dose were studied to determine methods of shielding the crew from the RPSs.

Here, we discuss the local photovoltaic characteristics of a structured bulk heterojunction, organic photovoltaic devices fabricated with a liquid carbazole, and a fullerene derivative based on analysis by scanning kelvin probe force microscopy (KPFM). Periodic photopolymerization induced by an interference pattern from two laser beams formed surface relief gratings (SRG) in the structured films. The surface potential distribution in the SRGs indicates the formation of donor and acceptor spatial distribution. Under illumination, the surface potential reversibly changed because of the generation of fullerene anions and hole transport from the films to substrates, which indicates that we successfully imaged the local photovoltaic characteristics of the structured photovoltaic devices. Using atomic force microscopy, we confirmed the formation of the SRG because of the material migration to the photopolymerized region of the films, which was induced by light exposure through photomasks. The structuring technique allows for the direct fabrication and the control of donor and acceptor spatial distribution in organic photonic and electronic devices with minimized material consumption. This in situ KPFM technique is indispensable to the fabrication of nanoscale electron donor and electron acceptor spatial distribution in the devices.

Ab initio many-body calculations of nucleon- 4He scattering with three-nucleon forces

We extend the ab initio no-core shell model/resonating-group method to include three-nucleon (3N) interactions for the description of nucleon-nucleus collisions. We outline the formalism, give algebraic expressions for the 3N-force integration kernels, and discuss computational aspects of two alternative implementations. The extended theoretical framework is then applied to nucleon- 4He elastic scattering using similarity-renormalization-group (SRG)-evolved nucleon-nucleon plus 3N potentials derived from chiral effective field theory. We analyze the convergence properties of the calculated phase shifts and explore their dependence upon the SRG evolution parameter. We include up to six excited states of the 4He target and find significant effects frommore » the inclusion of the chiral 3N force, e.g., it enhances the spin-orbit splitting between the 3/2 – and 1/2 – resonances and leads to an improved agreement with the phase shifts obtained from an accurate R-matrix analysis of the five-nucleon experimental data. As a result, we find remarkably good agreement with measured differential cross sections at various energies below the d+ 3H threshold, while analyzing powers manifest larger deviations from experiment for certain energies and angles.« less

2005-01-01

A 110-W Stirling Radioisotope Generator (SRG110) is being developed by Lockheed Martin Astronautics of Valley Forge, Pennsylvania, under contract to the Department of Energy of Germantown, Maryland. The generator will be a high-efficiency electric power source for NASA space exploration missions that can operate in the vacuum of deep space or in a gaseous atmosphere, such as on the surface of Mars. The generator converts heat supplied by the decay of a plutonium heat source into electric power for the spacecraft. In support of the SRG110 project, the NASA Glenn Research Center has established a technology effort that will provide some of the key data to ensure a successful transition to flight for what will be the first dynamic power system to be used in space. High system efficiency is obtained through the use of free-piston Stirling power-conversion technology. Glenn tasks include in-house testing of Stirling convertors and controllers, materials evaluation and heater head life assessment, structural dynamics, evaluation of electromagnetic interference, assessment of organics, and reliability analysis. There is also an advanced technology effort that is complementary to the near-term technology effort, intended to reduce the mass of the Stirling convertor and increase efficiency.

Epidemiologic data demonstrate that women involved with the criminal justice system in the United States are at high risk for sexually transmitted infections, including herpes simplex virus type 2 (HSV-2). Female defendants were recruited from a misdemeanor court to assess whether brief framed messages utilizing prospect theory could encourage testing for HSV-2. Participants were randomly assigned to a message condition (gain, loss, or control), completed an interviewer-administered survey assessing factors associated with antibody test uptake/refusal and were offered free point-of-care HSV-2 serologic testing. Although individuals in the loss-frame group accepted testing at the highest rate, an overall statistical difference in HSV-2 testing behavior by group (p ≤ .43) was not detected. The majority of the sample (74.6%) characterized receiving a serological test for HSV-2 as health affirming. However, this did not moderate the effect of the intervention nor was it significantly associated with test acceptance (p ≤ .82). Although the effects of message framing are subtle, the findings have important theoretical implications given the participants' characterization of HSV-2 screening as health affirming despite being a detection behavior. Implications of study results for health care providers interested in brief, low cost interventions are also explored.

The authors found an interaction between sex of participant and sex of defendant in the leniency bias toward a smiling defendant. Differences occurred for male participants when levying punishment for a smiling male defendant vs. a smiling female defendant and for a smiling male defendant vs. a nonsmiling male defendant, whereas differences did not occur for female participants. The authors found moderating effects of physical attractiveness and smiling between guilt and punishment. The only significant positive relationship between guilt and punishment occurred for the defendant whom participants rated low in physical attractiveness and who was not smiling. When guilty, the smiling and unattractive defendant received less punishment than did the smiling and attractive defendant. The authors discussed complex relationships between physical attractiveness, smiling, guilt, and punishment.

Apoptosis is an active process of cell death, which is an integral part of growth and development in multicellular organisms. The defender against cell death 1 (DAD1), the regulatory protein to inhibit the apoptosis process, was first cloned from the bay scallop Argopecten irradians by randomly sequencing a whole tissue cDNA library and rapid amplification of cDNA end (RACE). The full-length cDNA of the A. irradians DAD1 was 607 bp, consist of a 5'-terminal untranslated region (UTR) of 63 bp, a 3'-terminal UTR of 205 bp with a canonical polyadenylation signal sequence AATAAA and a poly (A) tail, and an open reading frame of 339 bp. The deduced amino acid sequence of the A. irradians DAD1 showed 75.5% identity to Araneus ventricosus, 74.5% to Drosophila melanogaster, and 73.6% to Homo sapiens, Sus scrofa, Mesocricetus auratus, Rattus norvegicus and Mus musculus. Excluding the Saccharomyces cerevisiae DAD1 homologue, all animal DAD1 including A. irradians DAD1 homologue formed a subgroup and all plant DAD1 proteins formed another subgroup in the phylogenetic analysis. The A. irradians DAD1 was expressed in all examined tissues including adductor muscle, mantle, gills, digestive gland, gonad and hemolymph, suggesting that A. irradians DAD1 is expressed in most body tissues. Furthermore, the mRNA expression levels of A. irradians DAD1 gene of hemolymph were particularly high after injury, suggesting that the gene is responsive to injury stimuli.

2005-02-01

The Step 2 General Purpose Heat Source (GPHS) is a slightly larger and more robust version of the heritage GPHS modules flown on previous Radioisotope Thermoelectric Generator (RTG) missions like Galileo, Ulysses, and Cassini. The Step 2 GPHS is to be used in future small radioisotope power sources, such as the Stirling Radioisotope Generator (SRG110) and the Multi-Mission Radioisotope Thermoelectric Generator (MMRTG). New features include an additional central web of Fine Weave Pierced Fabric (FWPF) graphite in the aeroshell between the two Graphite Impact Shells (GIS) to improve accidental reentry and impact survivability and an additional 0.1-inch of thickness to the aeroshell broad faces to improve ablation protection. This paper details the creation of the thermal model using Thermal Desktop and AutoCAD interfaces and provides comparisons of the model to results of previous thermal analysis models of the heritage GPHS. The results of the analysis show an anticipated decrease in total thermal gradient from the aeroshell to the iridium clads compared to the heritage results. In addition, the Step 2 thermal model is investigated under typical SRG110 boundary conditions, with cover gas and gravity environments included where applicable, to provide preliminary guidance for design of the generator. Results show that the temperatures of the components inside the GPHS remain within accepted design limits during all envisioned mission phases.

Do male breeding displays function to attract mates or defend territories? The explanatory role of mate and site fidelity

Many shorebirds show elaborate breeding displays that include aerial flights and ground displays accompanied by song. The mate attraction hypothesis suggests that breeding displays function to attract mates and maintain pair bonds, whereas the territory defense hypothesis suggests breeding displays function in defining and defending nesting and feeding territories. We tested these hypotheses in the Western Sandpiper (Calidris mauri) by contrasting the duration and level of male breeding displays among pairs that differed in their mate and site fidelity. As predicted by the mate attraction hypothesis, males performed the highest number of song sequences during pair formation, and males paired with their mate of a prior year sang less than males paired to new mates. Further, sitefaithful males mated to a new but experienced mate displayed significantly more than remated males or males new to the area. This suggests a male's prior familiarity with an area and his neighbors does not lessen his display rate as was predicted under the territory defense hypothesis. Limited support for the territory defense hypothesis came from observations of males performing breeding displays with neighboring males along nest territory boundaries. This behavior was short-lived, however, as males abandoned nesting areas after pair-formation and used adjacent or disjointed feeding areas during egg-laying and incubation. Male aggression (i.e., aerial and ground chases), as opposed to breeding displays, appeared to be the principal means of maintaining territory boundaries. Indeed, the rate at which males chased other males remained fairly constant and high throughout the breeding season. Male chasing behavior may also serve as a paternity guard to protect against extra-pair copulations. Our study also found that a female's prior breeding experience in an area correlated with a reduced display rate by her mate, particularly if that mate was new to the area. This indicates female

The present study examined legal perceptions of lesbian intimate partner violence (IPV) in an experimental context. Undergraduate women and men from the Southeastern United States (N = 217) read a trial summary in which the defendant was charged with physically assaulting her same-sex partner. The trial varied as to whether the victim and defendant were depicted via images as either feminine or masculine. Participants rendered verdicts and made judgments about the victim and defendant (e.g., credibility). Results indicated that the victim's and defendant's masculine or feminine appearance affected these judgments. Female participants viewed a masculine victim as more credible than a feminine victim when the defendant was masculine. When the victim was masculine, they viewed a masculine defendant as more responsible for the victim's injuries than a feminine defendant. Male participants had higher sympathy for a masculine versus feminine victim overall, but had more anger toward a masculine defendant versus a feminine defendant accused of assaulting a feminine victim. Finally, fewer participants mentioned the defendant's history of violence as a reason for a guilty of felony verdict for a feminine victim with a feminine defendant versus all other combinations of victim and defendant masculine/feminine appearance. Results are discussed in terms of gender stereotypes influencing legal decision-making in IPV cases among lesbian couples. © The Author(s) 2015.

Defending definitions of life.

PubMed

Mix, Lucas John

2015-01-01

Over the past 10 years, it has become unpopular to talk about definitions of life, under the assumption that attempts at a precise definition are counterproductive. Recent attempts have failed to meet strict philosophical criteria for definitions and have failed to reach consensus. I argue that provisional definitions are necessary for clear communications. Our current knowledge of biology justifies a number of universal claims about the category of life. Whether or not "life" represents a natural category, it maps to a number of important, observable processes. Given the importance of those processes and the extent of our knowledge, plural explicit definitions of life (and related categories) will be necessary for progress in astrobiology and origin-of-life studies as well as biology in general. I propose concrete categories related to, but not necessarily coextensive with, life for clear communication and hypothesis formation: Woese life, Darwin life, Haldane life.

Attractive but guilty: deliberation and the physical attractiveness bias.

PubMed

Patry, Marc W

2008-06-01

The current study examined the effect of jury deliberation on the tendency for mock jurors to find attractive defendants guilty less often. It was expected that there would be an interaction between group deliberation (yes or no) and defendant's appearance (plain-looking or attractive). It was hypothesized that mock jurors who did not deliberate would be more likely to find a plain-looking defendant guilty and that deliberation would mitigate this effect. The study was a 2 x 2 between-subjects factorial design. Participants were assigned randomly to one of four conditions: attractive defendant/deliberation, attractive defendant/no deliberation, plain-looking defendant/deliberation, and plain-looking defendant/no deliberation. A total of 172 undergraduates from a small, rural college in Vermont contributed to this study: mock jurors were 70 men and 52 women, ages ranged from 18 to 52 years (M=20.5, SD=4.9). The hypothesis was supported. Mock jurors who did not deliberate were more likely to find the plain-looking defendant guilty, whereas mock jurors who deliberated were more likely to find the attractive defendant guilty.

Defendants often provide accounts that minimize their responsibility for the accused offense. Jurors attribute responsibility to defendants and decide legal outcomes based on the given account. The current research examined the effects of accounts (i.e., excuse, justification, denial, and no explanation) and the defendant's remorse display (i.e., remorseful, remorseless) on mock jurors' judgments. Participants acquitted the defendant in the denial condition most often and recommended the most lenient punishment in the justification condition. The remorseful defendant was found guilty more frequently than the remorseless defendant in the no explanation and (marginally) excuse conditions. Limitations and future research are discussed.

Do defense attorney referrals for competence to stand trial evaluations depend on whether the client speaks English or Spanish?

PubMed

Varela, Jorge G; Boccaccini, Marcus T; Gonzalez, Ernie; Gharagozloo, Laadan; Johnson, Shara M

2011-12-01

Criminal defense attorneys (N = 142) responded to a survey asking them to read a vignette describing a Hispanic defendant charged with assault and rate the severity of the defendant's mental illness and likelihood of referring him for an evaluation of competence to stand trial (CST). The vignettes varied in terms of whether the defendant spoke English or Spanish, and whether his mental illness symptoms were obvious or ambiguous. Overall, attorneys rated the Spanish-speaking defendant as less mentally ill than the English-speaking defendant, and were less likely to refer the Spanish-speaking defendant for a CST evaluation. Attorneys who perceived more logistical barriers to seeking a CST evaluation in their local communities were less likely to refer the defendant for a CST evaluation, but only when the defendant spoke Spanish. These findings suggest attorney decisions were influenced by language, although further research is needed to identify the mechanism of this influence.

Early and mid-Holocene age for the Tempanos moraines, Laguna San Rafael, Patagonian Chile

2012-01-01

Data about the nature and timing of Holocene events from the Southern Hemisphere, especially in southern South America, are required to provide insight into the extent and nature of past climate change in a region where land-based records are restricted. Here we present the first use of single grain Optically Stimulated Luminescence (OSL) dating of a moraine sequence recording glacial advance along the western side of the Patagonian Icefields. Dates from the Tempanos moraines at Laguna San Rafael (LSR) show that the San Rafael Glacier (SRG) advanced to maximum Holocene positions during the period 9.3 to 9.7 ka and at 5.7 ka. Outwash lying beneath the moraine in its northern portion, dated to 7.7 ka, indicates that the glacier front was also advanced at this time. Since these advances span both the regional early Holocene warm-dry phase (11.5 ka to 7.8 ka) and the subsequent cooling and rise in precipitation in the mid-late Holocene (since 6.6 ka) we infer that the advances of the SRG are not simply climate-driven, but that the glacier has also probably responded strongly to non-climatic stimuli such as internal ice dynamics and the transition between calving and non-calving. Many westwards-flowing glaciers in Patagonia were probably calving during much of the Late Pleistocene and Holocene, so we conclude that establishing robust glacial chronologies where climatic and non-climatic factors cannot be distinguished is likely to remain a challenge.

A quick and simple method for simultaneous determination of the 30 ginsenosides (ginsenoside Ro, Rb1, Rb2, Rc, Rd, Re, Rf, Rg1, 20(S)-Rg2, 20(R)-Rg2, 20(S)-Rg3, 20(R)-Rg3, 20(S)-Rh1, 20(S)-Rh2, 20(R)-Rh2, F1, F2, F4, Ra1, Rg6, Rh4, Rk3, Rg5, Rk1, Rb3, Rk2, Rh3, compound Y, compound K, and notoginsenoside R1) in Panax ginseng preparations was developed and validated by an ultra performance liquid chromatography photo diode array detector. The separation of the 30 ginsenosides was efficiently undertaken on the Acquity BEH C-18 column with gradient elution with phosphoric acids. Especially the chromatogram of the ginsenoside Ro was dramatically enhanced by adding phosphoric acid. Under optimized conditions, the detection limits were 0.4 to 1.7 mg/L and the calibration curves of the peak areas for the 30 ginsenosides were linear over three orders of magnitude with a correlation coefficients greater than 0.999. The accuracy of the method was tested by a recovery measurement of the spiked samples which yielded good results of 89% to 118%. From these overall results, the proposed method may be helpful in the development and quality of P. ginseng preparations because of its wide range of applications due to the simultaneous analysis of many kinds of ginsenosides.

Effects and Mechanism of SO2 Inhalation on Rat Myocardial Collagen Fibers.

PubMed

Chen, Ping; Qiao, Decai; Liu, Xiaoli

2018-03-21

BACKGROUND This study investigates the effects and mechanism of sulfur dioxide (SO2) inhalation and exercise on rat myocardial collagen fiber. MATERIAL AND METHODS The rats were randomly divided into 4 groups: a control group (RG), an exercise group (EG), an SO2 pollution group (SRG), and an SO2 pollution and exercise group (SEG). Body weight, cardiac index, and left ventricular index in each group were compared. The myocardial hydroxyproline (Hyp) concentration was determined by pepsin acid hydrolysis. The interstitial myocardial collagen expression was measured by Sirius Red F3B in saturated carbazotic acid. The local myocardial angiotensin II type 1 receptor (AT1R) and connective tissue growth factor (CTGF) expression was tested by immunohistochemistry SABC method. RESULTS Compared with RG, the weight growth rate of EG, SRG, and SEG decreased significantly (P<0.01). Compared with EG, the body weight growth rate of SEG significantly decreased (P<0.01) and cardiac index and left ventricular index decreased but without a significant difference. Compared with EG, myocardial Hyp and collagen concentration, myocardial collagen volume fraction (CVF), perivascular collagen area (PVCA), and the expression of AT1R and CTGF in myocardium of SEG increased significantly (P<0.01). CONCLUSIONS SO2 inhalation and exercise will not only offset beneficial health effects of movement on the cardiovascular system, but also produce more unfavorable influences. People should pay attention to their environment when exercising, and try to avoid exercising in environments with SO2 pollution.

The purpose of the research was to determine whether European American and Latino mock jurors would demonstrate bias in death penalty decision making when mitigation evidence and defendant ethnicity and socioeconomic status (SES) were varied. A total of 561 actual venire persons acted as mock jurors and read a trial transcript that varied a defendant's case information (mitigating circumstances: strong/weak, defendant ethnicity: European American/Latino, and defendant SES: low/high). European American jurors recommended the death penalty significantly more often for the low SES Latino defendant when strength of mitigation evidence was weak. In addition, they also assigned this defendant higher culpability ratings and lower ratings on positive personality trait measures compared with all other conditions. Strong mitigation evidence contributed to lower guilt ratings by European American jurors for the high SES European American defendant. Latino jurors did not differ in their death penalty sentencing across defendant mitigation, ethnicity, or SES conditions. Discussion of in-group favoritism and out-group derogation, as well as suggestions for procedures to diminish juror bias in death penalty cases, is provided. (c) 2015 APA, all rights reserved).

We report here the isolation of a homologue of the potential anti-apoptotic gene, defender against apoptotic death (dad1 )from Chlamydomonas reinhardtii cells.Using polymerase chain reaction (PCR),we investigated its expression in the execution process of programmed cell death (PCD)in UV-C exposed dying C.reinhardtii cells.Reverse- transcriptase (RT)-PCR showed that C.reinhardtii dad1 amplification was drastically reduced in UV-C exposed dying C.reinhardtii cells.We connect the downregulation of dad1 with the upregulation of apoptosis protease activating factor-1 (APAF-1)and the physiological changes that occur in C.reinhardtii cells upon exposure to 12 J/m 2 UV-C in order to show a reciprocal relationship between proapoptotic and inhibitor of apoptosis factors.The temporal changes indicate a correlation between the onset of cell death and dad1 downregulation.The sequence of the PCR product of the cDNA encoding the dad1 homologue was aligned with the annotated dad1 (C_20215)from the Chlamydomonas database (http://genome.jgi-psf.org:8080/annotator/servlet/jgi.annotation.Annotation?pDb=chlre2); Annotation?pDb=chlre2 );this sequence was found to show 100% identity,both at the nucleotide and amino acid level. The 327 bp transcript showed an open reading frame of 87 amino acid residues.The deduced amino acid sequence of the putative C.reinhardtii DAD1 homologue showed 54% identity with Oryza sativa, 56 identity with Drosophila melanogaster, 66% identity with Xenopus laevis, and 64% identity with Homo sapiens,Sus scrofa,Gallus gallus,Rattus norvegicus and Mus musculus.

Characteristics of Misdemeanants Treated for Competency Restoration.

There are an estimated 60,000 evaluations annually for competence to stand trial for felony indictments and likely more for misdemeanor indictments. Thus, there is an increasing interest in determining factors associated with a defendant's likelihood of being restored to competence to stand trial. Although previous studies have found that a misdemeanor charge predicts significantly less likelihood of restoration of competence when compared with felony charges, states typically allow treatment facilities less time to restore misdemeanor defendants than felony defendants. As there are no studies examining factors associated with restoration of competence to stand trial for misdemeanor defendants, separately from felony defendants, we conducted a retrospective study to examine demographic, clinical, and forensic characteristics associated with restoration of competence to stand trial of misdemeanor defendants. Almost 70 percent of defendants regained competence to stand trial during the study period. When restorable, defendants regained competence in less than three weeks, on average, which addresses a current question in the field regarding time limits for restoration of competence to stand trial. Single marital status and length of stay in the treatment facility during restoration of competence to stand trial were significantly associated with restorability. States may consider such factors when developing and reviewing time limit policies in consideration of the Jackson v. Indiana ruling and when designing interventions aimed at restoring competence to stand trial to misdemeanor defendants in a cost-efficient manner. © 2016 American Academy of Psychiatry and the Law.

Medical practice: defendants and prisoners.

PubMed Central

Bowden, P

1976-01-01

It is argued in this paper that a doctor cannot serve two masters. The work of the prison medical officer is examined and it is shown that his dual allegiance to the state and to those individuals who are under his care results in activities which largely favour the former. The World Health Organisation prescribes a system of health ethics which indicates, in qualitative terms, the responsibility of each state for health provisions. In contrast, the World Medical Association acts as both promulgator and guardian of a code of medical ethics which determines the responsibilities of the doctor to his patient. In the historical sense medical practitioners have always emphasized the sanctity of the relationship with their patients and the doctor's role as an expert witness is shown to have centered around this bond. The development of medical services in prisons has focused more on the partnership between doctor and institution. Imprisonment in itself could be seen as prejudicial to health as are disciplinary methods which are more obviously detrimental. The involvement of medical practitioners in such procedures is discussed in the light of their role as the prisoner's personal physician. PMID:1003433

Content and comprehensibility of juvenile and adult tender-of-plea forms: implications for knowing, intelligent, and voluntary guilty pleas.

PubMed

Redlich, Allison D; Bonventre, Catherine L

2015-04-01

The overwhelming majority of criminal convictions in the United States are obtained through guilty pleas. To be constitutionally valid, guilty pleas must be knowing, voluntary, and intelligent. The information the defendant relies on to make a knowing, voluntary, and intelligent plea decision may be conveyed to the defendant through several modes, including but not limited to communication with defense counsel. Here, we address a mode that to our knowledge has previously not been systematically examined-tender-of-plea (ToP) forms. ToP forms are written instruments that inquire into whether the defendant understands and appreciates the plea decision and is capable of entering it. Using content analysis and comprehensibility measures, we examined a national sample of 208 tender-of-plea forms for both juvenile and adult defendants to determine what information they contained and their level of comprehensibility. The ToP forms were coded for several items concerning knowledge and voluntariness including rights waived, direct and collateral consequences, and capacity. Our findings show that the forms (a) are highly variable in their content, (b) exceed the reading comprehension of most defendants, and (c) are available more often to adult than to juvenile defendants. The implications of these findings are the forms should not be used to stand in place of "full and vigorous" judicial plea colloquies or meaningful defender-defendant discussions about plea decision-making.

The Failure of All Mothers or the Mother of All Failures? Juror Perceptions of Failure to Protect Laws.

PubMed

Stanziani, Marissa; Cox, Jennifer

2017-10-01

Failure to protect laws have been an area of interest among legal scholars, child and domestic violence advocates, and the social work and psychology fields with varying focuses on the societal underpinnings of the laws and their application. Despite the pervasive legal literature on "mother blaming" and the revictimization of battered women that these laws engender, few studies have empirically examined if "mother blaming" occurs in these cases, or if battered women are treated more harshly. The aim of the present study was to investigate the impact of defendant sex and presence of domestic violence on mock juror decision making in a failure to protect case. The influences of juror sex on decision making were also examined. Jury eligible community members read a summary of a case in which the defendant was charged with failing to protect their child from a third-party abuser. The sex of the defendant and the presence of domestic violence were manipulated. Participants then rendered a verdict, provided sentencing recommendations, and responded to attitudinal questions about the defendant and perpetrator. Mock jurors were more likely to find the defendant guilty and view the defendant more negatively when the defendant had been the victim of domestic violence. Defendant sex did not affect outcome measures; however, female jurors were more punitive than male jurors. Results are discussed in terms of "victim blaming" and labeling theory of intimate partner violence.

The toxicity of selected azo and anthracenedione dyes was studied using chronic exposures of embryo-larval fathead minnows (Pimephales promelas). Newly fertilized fathead minnow embryos were exposed through the egg stage, past hatching, through the larval stage (until 14 days post-hatch), with dye solutions renewed daily. The anthracenedione dyes Acid Blue 80 (AB80) and Acid Blue 129 (AB129) caused no effects in larval fish at the highest measured concentrations tested of 7700 and 6700 μg/L, respectively. Both azo dyes Disperse Yellow 7 (DY7) and Sudan Red G (SRG) decreased survival of larval fish, with LC50s (based on measured concentrations of dyes in fish exposure water) of 25.4 μg/L for DY7 and 16.7 μg/L for SRG. Exposure to both azo dyes caused a delayed response, with larval fish succumbing 4-10 days after hatch. If the exposures were ended at the embryo stage or just after hatch, the potency of these two dyes would be greatly underestimated. Concentrations of dyes that we measured entering the Canadian environment were much lower than those that affected larval fish survival in the current tests. In a total of 162 samples of different municipal wastewater effluents from across Canada assessed for these dyes, all were below detection limits. The similarities of the structures and larval fish responses for the two azo and two anthracenedione dyes in this study support the use of read-across data for risk assessment of these classes of compounds.

Sex, sexual orientation, and sexism: what influence do these factors have on verdicts in a crime-of-passion case?

PubMed

Ragatz, Laurie L; Russell, Brenda

2010-01-01

This study investigated the influence of defendant sex, sexual orientation, and participant sex on perceptions of a crime-of-passion. An online sample of 458 individuals read a scenario describing a homicide and provided judgments of verdict, sentence length, legal elements, and sexism. We hypothesized heterosexual female defendants would most likely receive a verdict of manslaughter, be found less guilty, and receive shorter sentences. We were also interested in whether benevolent sexism would contribute to defendant culpability decisions. Lastly, perceptions of legal elements for manslaughter (e.g., great provocation) and murder (e.g., intentionality of actions) were explored. Results demonstrated heterosexual female defendants were less guilty and received the shortest sentences. Also, heterosexual defendants were most likely to meet the manslaughter legal elements. Benevolent sexism contributed significantly to guilt perceptions.

The Influence of Biomedical Information and Childhood History on Sentencing.

A recent trend in court is for defense attorneys to introduce brain scans and other forms of biomedical information (BI) into criminal trials as mitigating evidence. The present study investigates how BI, when considered in combination with a defendant's childhood information (CI), can influence the length of a defendant's sentence. We hypothesized that certain combinations of BI and CI result in shorter sentences because they suggest that the defendant poses less of a threat to society. Participants were asked to read accounts of the trial of a murder suspect and, based on the information therein, recommend a sentence as if they were the judge. The defendant was diagnosed with psychopathy, but biomedical information regarding that diagnosis was included or excluded depending on the BI condition. The defendant was further described as growing up in either a loving or abusive family. The results showed that, if BI was present in the trial account, the defendant from an abusive family was perceived as less of a threat to society and received a shorter recommended sentence than if the defendant had been from a loving family. If BI was absent from the account, the pattern was reversed: the defendant from a loving family was perceived as less of a threat to society and received a shorter recommended sentence than if he had been from an abusive family. Implications for the use of BI and CI in court trials are discussed, as well as their relationship to free will and the function of punishment as retribution and utility.

Research on 1vs1 sub-phases in team sports has shown how one player coordinates his/her actions with his/her opponent and the location of a target/goal to attain performance objectives. In this study, we extended this approach to analysis of 5vs5 competitive performance in the team sport of futsal to provide a performance analysis framework that explains how players coordinate their actions to create/prevent opportunities to score goals. For this purpose, we recorded all 10 futsal matches of the 2009 Lusophony Games held in Lisbon. We analysed the displacement trajectories of a shooting attacker and marking defender in plays ending in a goal, a goalkeeper's save, and a defender's interception, at four specific moments during performance: (1) assisting attacker's ball reception and (2) moment of passing, (3) shooter's ball reception, and (4), shot on goal. Statistical analysis showed that when a goal was scored, the defender's angle to the goal and to the attacker tended to decrease, the attacker was able to move to the same distance to the goal alongside the defender, and the attacker was closer to the defender and moving at the same velocity (at least) as the defender. This study identified emergent patterns of coordination between attackers and defenders under key competitive task constraints, such as the location of the goal, which supported successful performance in futsal.

When emotionality trumps reason: a study of individual processing style and juror bias.

PubMed

Gunnell, Justin J; Ceci, Stephen J

2010-01-01

"Cognitive Experiential Self Theory" (CEST) postulates that information-processing proceeds through two pathways, a rational one and an experiential one. The former is characterized by an emphasis on analysis, fact, and logical argument, whereas the latter is characterized by emotional and personal experience. We examined whether individuals influenced by the experiential system (E-processors) are more susceptible to extralegal biases (e.g. defendant attractiveness) than those influenced by the rational system (R-processors). Participants reviewed a criminal trial transcript and defendant profile and determined verdict, sentencing, and extralegal susceptibility. Although E-processors and R-processors convicted attractive defendants at similar rates, E-processors were more likely to convict less attractive defendants. Whereas R-processors did not sentence attractive and less attractive defendants differently, E-processors gave more lenient sentences to attractive defendants and harsher sentences to less attractive defendants. E-processors were also more likely to report that extralegal factors would change their verdicts. Further, the degree to which emotionality trumped rationality within an individual, as measured by a novel scoring method, linearly correlated with harsher sentences and extralegal influence. In sum, the results support an "unattractive harshness" effect during guilt determination, an attraction leniency effect during sentencing and increased susceptibility to extralegal factors within E-processors.

2014-01-01

The paper presents a scientometric analysis of PhD theses on gerontological topics in Russian humanities (excluding economics) for the period from 1995 to 2012. During this period, 253 PhD theses (238 of "candidate dissertations," and 15 of "doctoral dissertations") were defended in Russia. Almost half of them were defended during the boom years (2005-2006; 2009-2010). The number of theses defended in the 2000-s has increased significantly compared to the second half of 1990-s. However for gerontological PhD-s overall as a percentage of all theses defended in Russian humanities, the number hardly changed and remained small (less than 0.3%). The leading discipline in the study of aging (within the humanities) is sociology accounting for more than a third of all defended theses. Though the theses were defended in 48 cities, more than half of them were defended in 3 cities, which are Moscow, St. Petersburg and Saratov. Thematic analysis showed that the leading position was occupied by two topics: "the elderly and the state" (42%) and "(re)socialization/adaptation of the elderly" (25%). 14% of the works are devoted to intergenerational relations and social status of the elderly. Other topics (old man/woman's personality, self-perceptions of aging, violence and crime against the elderly, loneliness, discrimination, etc.) are presented by very few studies.

This study examined the influence of victim sex, mock juror sex, and type of child abuse (physical, sexual, emotional, and neglect) on mock jurors' assessments of eyewitness and defendant integrity, continuous guilt ratings, dichotomous verdicts, and sentencing recommendations. Participants read one of eight versions of a trial transcript and then answered a self-report questionnaire. Female mock jurors were significantly more likely to find the defendant guilty overall. Moreover, female mock jurors recommended significantly longer sentences for defendants in sexual abuse cases; whereas, male mock jurors recommended significantly longer sentences for defendants in sexual and physical abuse cases. Male mock jurors perceived the defendant more favorably than female mock jurors; whereas, female mock jurors perceived the alleged victim more favorable than male mock jurors. These results suggest that juror sex may be an influential factor in child abuse cases overall. Copyright © 2017 Elsevier Ltd. All rights reserved.

Cyber-system defenders face the challenging task of protecting critical assets and information continually against multiple types of malicious attackers. Defenders typically operate within resource constraints while attackers operate at relatively low costs. As a result, design and development of resilient cyber-systems that can support mission goals under attack while accounting for the dynamics between attackers and defenders is an important research problem.

The golden mimicry complex uses a wide spectrum of defence to deter a community of predators

2017-01-01

Mimicry complexes typically consist of multiple species that deter predators using similar anti-predatory signals. Mimics in these complexes are assumed to vary in their level of defence from highly defended through to moderately defended, or not defended at all. Here, we report a new multi-order mimicry complex that includes at least 140 different putative mimics from four arthropod orders including ants, wasps, bugs, tree hoppers and spiders. All members of this mimicry complex are characterised by a conspicuous golden body and an ant Gestalt, but vary substantially in their defensive traits. However, they were similarly effective at deterring predators - even mildly defended mimics were rarely eaten by a community of invertebrate and vertebrate predators both in the wild and during staged trials. We propose that despite the predominance of less defended mimics the three predatory guilds avoid the mimics because of the additive influence of the various defensive traits.

"But He's a Star Football Player!": How Social Status Influences Mock Jurors' Perceptions in a Sexual Assault Case.

PubMed

Pica, Emily; Sheahan, Chelsea; Pozzulo, Joanna

2017-06-01

There have been several recent, high-profile cases in the media that have shed light on the perceived leniency in sentencing defendants in sexual assault cases. In a number of these cases, the defendant was well known within their community (e.g., Brock Turner; People v. Turner) or nationally (e.g., Ghomeshi; R v. Ghomeshi). The purpose of this study was to examine how the social status of the defendant (low vs. high), victim social status (low vs. high), victim gender (male vs. female), and the reason the victim was unconscious during the assault (consuming alcohol vs. consuming cold medicine) influenced mock jurors' decisions in a sexual assault case. Mock jurors ( N = 489) read a mock trial transcript depicting an alleged sexual assault. Mock jurors were asked to render a dichotomous verdict, continuous guilt rating, and rate their perceptions of the victim and defendant. There was no influence of the variables on mock jurors' dichotomous verdicts; however, social status influenced guilt ratings. There also was a combined influence of the defendant's social status and the reason the victim was unconscious such that when the defendant was described as low status, and the victim was unconscious due to alcohol consumption, the defendant received higher guilt ratings compared with when the victim was unconscious due to cold medicine. Moreover, the victim was perceived as having more control over the situation when the defendant was the star quarterback (i.e., high status), the victim was female, and she was unconscious due to alcohol consumption compared with cold medicine. These results suggest that victims may be blamed based on their perceived social status and other factors that may have influenced their control over the sexual assault, such as alcohol consumption.

Improving granulocyte function may represent an effective therapy for Crohn's disease (CD). We performed a Phase I-2 trial of sargramostim (SRG) in children with CD. This was multicenter, open-label study in 6-16-year-old patients with moderate to severely active CD. Patients received either 4 or 6 microg/kg SRG subcutaneously daily for 8 weeks, with and without concomitant corticosteroids (CS). The primary endpoint was identification of a safe and tolerable dose in children. The secondary endpoint was establishment of the pharmacokinetics (PK). Efficacy, a tertiary endpoint, was measured by the Pediatric CD Activity Index (PCDAI). Response was defined as a decrease from baseline of > or =12.5 points and remission as absolute PCDAI of < or =10. In all, 22 patients were enrolled: 12 and 10 received 4 and 6 mg/kg, respectively; 19 completed the course. Both doses were found to be safe and well tolerated. Mild injection-site reactions occurred in 90% of patients. Three patients required dose reductions due to elevated absolute neutrophil counts. Following 4 microg/kg the mean area under the curve (AUC) was 2.64 and 2.80 ngh/mL for the 6-11- and 12-16-year-old groups, respectively. The mean half-life (t(1/2)) was 1.22 and 1.59 hours, respectively. Following 6 microg/kg, the mean AUC was 5.01 ngh/mL for the 12-16-year-old group, a 1.8-fold increase. A total of 16/18 patients (88%) achieved remission or response. Sargramostim at both 4 and 6 mg/kg was well tolerated. PK analysis suggested dose proportionality unaffected by CS exposure. Remission and response data are encouraging, but further trials are needed to assess efficacy.

Vibration Modal Characterization of a Stirling Convertor via Base-Shake Excitation

NASA Technical Reports Server (NTRS)

Suarez, Vicente J.; Goodnight, Thomas W.; Hughes, William O.; Samorezov, Sergey

2003-01-01

The U.S. Department of Energy (DOE), Lockheed Martin (LM), Stirling Technology Company (STC), and NASA John H. Glenn Research Center (GRC) are currently developing a high-efficiency Stirling convertor for use in a Stirling Radioisotope Generator (SRG). NASA and DOE have identified the SRG for potential use as an advanced power system for future NASA Space Science missions, providing spacecraft onboard electric power for deep space missions and power for unmanned Mars rovers. Low-level, baseshake sine vibration tests were conducted on the Stirling Technology Demonstration Convertor (TDC), at NASA GRC's Structural Dynamics Laboratory, in February 2001, as part of the development of this Stirling technology. The purpose of these tests was to provide a better understanding of the TDC's internal dynamic response to external vibratory base excitations. The knowledge obtained can therein be used to help explain the success that the TDC enjoyed in its previous random vibration qualification tests (December 1999). This explanation focuses on the TDC s internal dynamic characteristics in the 50 to 250 Hz frequency range, which corresponds to the maximum input levels of its qualification random vibration test specification. The internal dynamic structural characteristics of the TDC have now been measured in two separate tests under different motoring and dynamic loading conditions: (1) with the convertor being electrically motored, under a vibratory base-shake excitation load, and (2) with the convertor turned off, and its alternator internals undergoing dynamic excitation via hammer impact loading. This paper addresses the test setup, procedure and results of the base-shake vibration testing conducted on the motored TDC, and will compare these results with those results obtained from the dynamic impact tests (May 2001) on the nonmotored TDC.

Overview of NASA GRC Stirling Technology Development

The Stirling Radioisotope Generator (SRG) is currently being developed by Lockheed Martin Astronautics (LMA) under contract to the Department of Energy (DOE). The generator will be a high efficiency electric power source for NASA Space Science missions with the ability to operate in vacuum or in an atmosphere such as on Mars. High efficiency is obtained through the use of free-piston Stirling power conversion. Power output will be greater than 100 watts at the beginning of life with the decline in power largely due to the decay of the plutonium heat source. In support of the DOE SRG project, the NASA Glenn Research Center (GRC) has established a technology effort to provide data to ensure a successful transition to flight for what will be the first dynamic power system in space. Initially, a limited number of areas were selected for the effort, however this is now being expanded to more thoroughly cover key technical issues. There is also an advanced technology effort that is complementary to the near-term technology effort. Many of the tests use the 55-We Technology Demonstration Convertor (TDC). There have been multiple controller tests to support the LMA flight controller design effort. Preparation is continuing for a thermal/vacuum system demonstration. A pair of flight prototype TDC s have been placed on continuous operation. Heater head life assessment continues, with the material data being refined and the analysis moving toward the system perspective. Magnet aging tests continue to characterize any possible aging in the strength or demagnetization resistance of the magnets in the linear alternator. A reliability effort has been initiated to help guide the development activities with focus on the key components and subsystems. This paper will provide an overview of some of the GRC technical efforts, including the status, and a description of future efforts.

The capital trial, by its nature, is fraught with emotionally disturbing elements that jurors must face when deciding the ultimate fate of a guilty defendant. A confluence of mitigating and aggravating factors influences a capital jury's decision to impose a sentence of death. The presence or absence of defendant remorse in these cases may make all the difference in whether a capital defendant's life is spared. This commentary examines the onerous emotional toll encountered by capital jurors in light of the findings of Corwin and colleagues regarding defendant remorse and juror's need for affect. The commentary also presents practical and ethics-related considerations that should be kept in mind when reflecting on their study.

A new initiative underway at the National Renewable Energy Laboratory is intended to prevent hackers from gaining control of parts of the nation's power grid, potentially damaging electrical equipment and causing localized power outages. Our nation's power grid is evolving to be more responsive to changing power needs, more able to integrate renewable energy, more efficient, and more reliable. One key element of this evolution is adding communication and control devices to the power grid, closer to the end user, so that utilities have greater situational awareness of the grid and can respond quickly to disturbances.

Coral Skeletons Defend against Ultraviolet Radiation

PubMed Central

Reef, Ruth; Kaniewska, Paulina; Hoegh-Guldberg, Ove

2009-01-01

Background Many coral reef organisms are photosynthetic or have evolved in tight symbiosis with photosynthetic symbionts. As such, the tissues of reef organisms are often exposed to intense solar radiation in clear tropical waters and have adapted to trap and harness photosynthetically active radiation (PAR). High levels of ultraviolet radiation (UVR) associated with sunlight, however, represent a potential problem in terms of tissue damage. Methodology/Principal Findings By measuring UVR and PAR reflectance from intact and ground bare coral skeletons we show that the property of calcium carbonate skeletons to absorb downwelling UVR to a significant extent, while reflecting PAR back to the overlying tissue, has biological advantages. We placed cnidarians on top of bare skeletons and a UVR reflective substrate and showed that under ambient UVR levels, UVR transmitted through the tissues of cnidarians placed on top of bare skeletons were four times lower compared to their counterparts placed on a UVR reflective white substrate. In accordance with the lower levels of UVR measured in cnidarians on top of coral skeletons, a similar drop in UVR damage to their DNA was detected. The skeletons emitted absorbed UVR as yellow fluorescence, which allows for safe dissipation of the otherwise harmful radiation. Conclusions/Significance Our study presents a novel defensive role for coral skeletons and reveals that the strong UVR absorbance by the skeleton can contribute to the ability of corals, and potentially other calcifiers, to thrive under UVR levels that are detrimental to most marine life.

Cyber situation awareness: modeling detection of cyber attacks with instance-based learning theory.

Dutt, Varun; Ahn, Young-Suk; Gonzalez, Cleotilde

To determine the effects of an adversary's behavior on the defender's accurate and timely detection of network threats. Cyber attacks cause major work disruption. It is important to understand how a defender's behavior (experience and tolerance to threats), as well as adversarial behavior (attack strategy), might impact the detection of threats. In this article, we use cognitive modeling to make predictions regarding these factors. Different model types representing a defender, based on Instance-Based Learning Theory (IBLT), faced different adversarial behaviors. A defender's model was defined by experience of threats: threat-prone (90% threats and 10% nonthreats) and nonthreat-prone (10% threats and 90% nonthreats); and different tolerance levels to threats: risk-averse (model declares a cyber attack after perceiving one threat out of eight total) and risk-seeking (model declares a cyber attack after perceiving seven threats out of eight total). Adversarial behavior is simulated by considering different attack strategies: patient (threats occur late) and impatient (threats occur early). For an impatient strategy, risk-averse models with threat-prone experiences show improved detection compared with risk-seeking models with nonthreat-prone experiences; however, the same is not true for a patient strategy. Based upon model predictions, a defender's prior threat experiences and his or her tolerance to threats are likely to predict detection accuracy; but considering the nature of adversarial behavior is also important. Decision-support tools that consider the role of a defender's experience and tolerance to threats along with the nature of adversarial behavior are likely to improve a defender's overall threat detection.

Optimal Resource Allocation in Electrical Network Defense

DOE Office of Scientific and Technical Information (OSTI.GOV)

Yao, Y; Edmunds, T; Papageorgiou, D

2004-01-15

Infrastructure networks supplying electricity, natural gas, water, and other commodities are at risk of disruption due to well-engineered and coordinated terrorist attacks. Countermeasures such as hardening targets, acquisition of spare critical components, and surveillance can be undertaken to detect and deter these attacks. Allocation of available countermeasures resources to sites or activities in a manner that maximizes their effectiveness is a challenging problem. This allocation must take into account the adversary's response after the countermeasure assets are in place and consequence mitigation measures the infrastructure operation can undertake after the attack. The adversary may simply switch strategies to avoid countermeasuresmore » when executing the attack. Stockpiling spares of critical energy infrastructure components has been identified as a key element of a grid infrastructure defense strategy in a recent National Academy of Sciences report [1]. Consider a scenario where an attacker attempts to interrupt the service of an electrical network by disabling some of its facilities while a defender wants to prevent or minimize the effectiveness of any attack. The interaction between the attacker and the defender can be described in three stages: (1) The defender deploys countermeasures, (2) The attacker disrupts the network, and (3) The defender responds to the attack by rerouting power to maintain service while trying to repair damage. In the first stage, the defender considers all possible attack scenarios and deploys countermeasures to defend against the worst scenarios. Countermeasures can include hardening targets, acquiring spare critical components, and installing surveillance devices. In the second stage, the attacker, with full knowledge of the deployed countermeasures, attempts to disable some nodes or links in the network to inflict the greatest loss on the defender. In the third stage, the defender re-dispatches power and restores disabled

Arresting and convicting the innocent: the potential role of an "inappropriate" emotional display in the accused.

PubMed

Heath, Wendy P

2009-01-01

Research from both simulated and actual jurors has demonstrated that the defendant's emotional display can influence legal decisions. The purpose of this paper is to review the evidence regarding the influence of the defendant's emotional display, and to consider the potential role of suspect and defendant emotion in wrongful convictions. It is possible that the lack of "appropriate" emotion during questioning or interrogation may lead investigators to create a mind-set that the suspect is the guilty party; as a result, they may be less inclined to investigate other leads. During a trial, the defendant's perceived level of emotion can potentially mislead jurors (e.g. a defendant displaying a low level of emotion leading people to believe, inappropriately, that he is guilty). After a review of the pertinent literature and examples of relevant cases, reasons are provided regarding why one's emotional display may be of limited diagnostic value. Future research ideas are proposed in an effort to determine more definitively the impact of the emotional display of the accused on legal decisions. (c) 2009 John Wiley & Sons, Ltd.

Exploring sex disparity in sentencing outcomes: a focus on narcotics offenders in South Korea.

PubMed

Hartley, Richard D; Kwak, Dae-Hoon; Park, Mirang; Lee, Min-Sik

2011-04-01

Most research on sentencing outcomes reveals that legally relevant factors such as the seriousness of the offense and prior criminal record are primary determinants. There is, however, a substantial body of research that finds that extralegal factors such as a defendant's sex also influence these outcomes. Most of these latter studies conclude that female defendants receive less severe outcomes compared to their male counterparts. Most of this research, however, is limited to Western societies. To extend this body of research, the current study examines sex differences in sentencing practices for a sample of narcotics offenders in South Korea. Results support previous research; female drug offenders in South Korea are generally treated more leniently than their male counterparts. Tests for interaction effects reveal that the defendant's sex also interacts with other constellations of factors to produce lenient treatment for certain female defendants. These tests, however, also reveal that lenient sentence outcomes are not extended to all female defendants; those with prior drug convictions do not fare better than their male counterparts at the incarceration decision.

Discrimination and instructional comprehension: guided discretion, racial bias, and the death penalty.

Lynch, M; Haney, C

2000-06-01

This study links two previously unrelated lines of research: the lack of comprehension of capital penalty-phase jury instructions and discriminatory death sentencing. Jury-eligible subjects were randomly assigned to view one of four versions of a simulated capital penalty trial in which the race of defendant (Black or White) and the race of victim (Black or White) were varied orthogonally. Dependent measures included a sentencing verdict (life without the possibility of parole or the death penalty), ratings of penalty phase evidence, and a test of instructional comprehension. Results indicated that instructional comprehension was poor overall and that, although Black defendants were treated only slightly more punitively than White defendants in general, discriminatory effects were concentrated among participants whose comprehension was poorest. In addition, the use of penalty phase evidence differed as a function of race of defendant and whether the participant sentenced the defendant to life or death. The study suggest that racially biased and capricious death sentencing may be in part caused or exacerbated by the inability to comprehend penalty phase instructions.

When different clinicians evaluate the same criminal defendant's legal sanity, do they reach the same conclusion? Because Hawaii law requires multiple, independent evaluations when questions about legal sanity arise, Hawaii allows for the first contemporary study of the reliability of legal sanity opinions in routine practice in the United States. We examined 483 evaluation reports, addressing 165 criminal defendants, in which up to three forensic psychiatrists or psychologists offered independent opinions on a defendant's legal sanity. Evaluators reached unanimous agreement regarding legal sanity in only 55.1% of cases. Evaluators tended to disagree more often when a defendant was under the influence of drugs or alcohol at the time of the offense. But evaluators tended to agree more often when they agreed about diagnosing a psychotic disorder, or when the defendant had been psychiatrically hospitalized shortly before the offense. In court, judges followed the majority opinion among evaluators in 91% of cases. But when judges disagreed with the majority opinion, they usually did so to find defendants legally sane, rather than insane. Overall, this study indicates that reliability among practicing forensic evaluators addressing legal sanity may be poorer than the field has tended to assume. Although agreement appears more likely in some cases than others, the frequent disagreements suggest a need for improved training and practice.

In-group defense, out-group aggression, and coordination failures in intergroup conflict.

Intergroup conflict persists when and because individuals make costly contributions to their group's fighting capacity, but how groups organize contributions into effective collective action remains poorly understood. Here we distinguish between contributions aimed at subordinating out-groups (out-group aggression) from those aimed at defending the in-group against possible out-group aggression (in-group defense). We conducted two experiments in which three-person aggressor groups confronted three-person defender groups in a multiround contest game (n = 276; 92 aggressor-defender contests). Individuals received an endowment from which they could contribute to their group's fighting capacity. Contributions were always wasted, but when the aggressor group's fighting capacity exceeded that of the defender group, the aggressor group acquired the defender group's remaining resources (otherwise, individuals on both sides were left with the remainders of their endowment). In-group defense appeared stronger and better coordinated than out-group aggression, and defender groups survived roughly 70% of the attacks. This low success rate for aggressor groups mirrored that of group-hunting predators such as wolves and chimpanzees (n = 1,382 cases), hostile takeovers in industry (n = 1,637 cases), and interstate conflicts (n = 2,586). Furthermore, whereas peer punishment increased out-group aggression more than in-group defense without affecting success rates (Exp. 1), sequential (vs. simultaneous) decision-making increased coordination of collective action for out-group aggression, doubling the aggressor's success rate (Exp. 2). The relatively high success rate of in-group defense suggests evolutionary and cultural pressures may have favored capacities for cooperation and coordination when the group goal is to defend, rather than to expand, dominate, and exploit.

Gender differences in jurors' perceptions of infanticide involving disabled and non-disabled infant victims.

2011-02-01

The present study investigated the influence of juror gender and infant victim disability on jurors' reactions to infanticide cases. Participants (men and women undergraduates) read a summary of a mock trial involving alleged father-perpetrated infanticide. The infant was described as severely mentally disabled or as not disabled. Participants completed a series of case-related judgments (e.g., guilt; sentence; and empathy, sympathy, and similarity toward the defendant and victim). There were pervasive gender differences such that compared to men, women mock jurors rendered more guilty verdicts, perceived the father/defendant as having greater intent to kill his infant, and felt less similar to the defendant. Compared to men, women also believed the father was more responsible and the pneumonia was less responsible for the infant's death, had less sympathy and empathy for the defendant, endorsed more negative beliefs about the father, and were more likely to believe the infant was a unique person. Mediational analyses revealed that these statistically significant effects were explained, in part, by gender differences in attitudes toward the defendant. Further, whether the infant victim was portrayed as severely disabled (versus developmentally normal) had little effect on central case judgments such as verdict, but jurors who believed the infant was severely disabled gave significantly shorter sentences to the defendant, were less likely to perceive the defendant as mentally ill, and felt significantly less empathy for and similarity to the infant victim. Although juror gender consistently predicted juror's judgments, there were fewer effects of disability status. Even so, bias against disabled infants manifested for several dependant variables. This research can inform legal professionals about the potential for bias in juror decision-making, and in turn, help facilitate fairness and justice for the youngest and most vulnerable victims of child abuse. 2011

Long-term competence restoration.

Morris, Douglas R; DeYoung, Nathaniel J

2014-01-01

While the United States Supreme Court's Jackson v. Indiana decision and most state statutes mandate determinations of incompetent defendants' restoration probabilities, courts and forensic clinicians continue to lack empirical evidence to guide these determinations and do not yet have a consensus regarding whether and under what circumstances incompetent defendants are restorable. The evidence base concerning the restoration likelihood of those defendants who fail initial restoration efforts is even further diminished and has largely gone unstudied. In this study, we examined the disposition of a cohort of defendants who underwent long-term competence restoration efforts (greater than six months) and identified factors related to whether these defendants were able to attain restoration and adjudicative success. Approximately two-thirds (n = 52) of the 81 individuals undergoing extended restoration efforts were eventually deemed restored to competence. Lengths of hospitalization until successful restoration are presented with implications for the reasonable length of time that restoration efforts should persist. Older individuals were less likely to be restored and successfully adjudicated, and individuals with more severe charges and greater factual legal understanding were more likely to be restored and adjudicated. The significance of these findings for courts and forensic clinicians is discussed.

School bullying and the mechanisms of moral disengagement.

PubMed

Thornberg, Robert; Jungert, Tomas

2014-01-01

The aim of the present study was to examine to what degree different mechanisms of moral disengagement were related to age, gender, bullying, and defending among school children. Three hundred and seventy-two Swedish children ranging in age from 10 to 14 years completed a questionnaire. Findings revealed that boys expressed significantly higher levels of moral justification, euphemistic labeling, diffusion of responsibility, distorting consequences, and victim attribution, as compared with girls. Whereas boys bullied others significantly more often than girls, age was unrelated to bullying. Moral justification and victim attribution were the only dimensions of moral disengagement that significantly related to bullying. Furthermore, younger children and girls were more likely to defend victims. Diffusion of responsibility and victim attribution were significantly and negatively related to defending, while the other dimensions of moral disengagement were unrelated to defending. © 2013 Wiley Periodicals, Inc.

2012-05-01

This study investigated the influence of interpersonal coordination tendencies on performance outcomes of 1-vs-1 sub-phases in youth soccer. Eight male developing soccer players (age: 11.8 ± 0.4 years; training experience: 3.6 ± 1.1 years) performed an in situ simulation of a 1-vs-1 sub-phase of soccer. Data from 82 trials were obtained with motion-analysis techniques, and relative phase used to measure the space-time coordination tendencies of attacker-defender dyads. Approximate entropy (ApEn) was then used to quantify the unpredictability of interpersonal interactions over trials. Results revealed how different modes of interpersonal coordination emerging from attacker-defender dyads influenced the 1-vs-1 performance outcomes. High levels of space-time synchronisation (47%) and unpredictability in interpersonal coordination processes (ApEn: 0.91 ± 0.34) were identified as key features of an attacking player's success. A lead-lag relation attributed to a defending player (34% around -30° values) and a more predictable coordination mode (ApEn: 0.65 ± 0.27, P < 0.001), demonstrated the coordination tendencies underlying the success of defending players in 1-vs-1 sub-phases. These findings revealed how the mutual influence of each player on the behaviour of dyadic systems shaped emergent performance outcomes. More specifically, the findings showed that attacking players should be constrained to exploit the space-time synchrony with defenders in an unpredictable and creative way, while defenders should be encouraged to adopt postures and behaviours that actively constrain the attacker's actions.

Efficient Allocation of Resources for Defense of Spatially Distributed Networks Using Agent-Based Simulation.

PubMed

Kroshl, William M; Sarkani, Shahram; Mazzuchi, Thomas A

2015-09-01

This article presents ongoing research that focuses on efficient allocation of defense resources to minimize the damage inflicted on a spatially distributed physical network such as a pipeline, water system, or power distribution system from an attack by an active adversary, recognizing the fundamental difference between preparing for natural disasters such as hurricanes, earthquakes, or even accidental systems failures and the problem of allocating resources to defend against an opponent who is aware of, and anticipating, the defender's efforts to mitigate the threat. Our approach is to utilize a combination of integer programming and agent-based modeling to allocate the defensive resources. We conceptualize the problem as a Stackelberg "leader follower" game where the defender first places his assets to defend key areas of the network, and the attacker then seeks to inflict the maximum damage possible within the constraints of resources and network structure. The criticality of arcs in the network is estimated by a deterministic network interdiction formulation, which then informs an evolutionary agent-based simulation. The evolutionary agent-based simulation is used to determine the allocation of resources for attackers and defenders that results in evolutionary stable strategies, where actions by either side alone cannot increase its share of victories. We demonstrate these techniques on an example network, comparing the evolutionary agent-based results to a more traditional, probabilistic risk analysis (PRA) approach. Our results show that the agent-based approach results in a greater percentage of defender victories than does the PRA-based approach. © 2015 Society for Risk Analysis.

Sleep-related violence and sexual behavior in sleep: a systematic review of medical-legal case reports.

To review systematically medical-legal cases of sleep-related violence (SRV) and sexual behavior in sleep (SBS). We searched Pubmed and PsychINFO (from 1980 to 2012) with pre-specified terms. We also searched reference lists of relevant articles. Case reports in which a sleep disorder was purported as the defense during a criminal trial and in which information about the forensic evaluation of the defendant was provided. Information about legal issues, defendant and victim characteristics, circumstantial factors, and forensic evaluation was extracted from each case. A qualitative-comparative assessment of cases was performed. Eighteen cases (9 SRV and 9 SBS) were included. The charge was murder or attempted murder in all SRV cases, while in SBS cases the charge ranged from sexual touching to rape. The defense was based on sleepwalking in 11 of 18 cases. The trial outcome was in favor of the defendant in 14 of 18 cases. Defendants were relatively young males in all cases. Victims were usually adult relatives of the defendants in SRV cases and unrelated young girls or adolescents in SBS cases. In most cases the criminal events occurred 1-2 hours after the defendant's sleep onset, and both proximity and other potential triggering factors were reported. The forensic evaluations widely differed from case to case. SRV and SBS medical-legal cases did not show apparent differences, except for the severity of the charges and the victim characteristics. An international multidisciplinary consensus for the forensic evaluation of SRV and SBS should be developed as an urgent priority.

Commentary: Perception of remorse by mock jurors in a capital murder trial.

PubMed

Batista, Leonardo M; Myers, Wade

2012-01-01

The study by Corwin et al. adds to the emerging but limited data on the impact of defendant remorse on sentencing decisions. The authors studied verbal and nonverbal expressions of defendant remorse and whether they were perceived as remorseful by mock jurors. They found that incongruent verbal and nonverbal behavior, as well as mock jurors' willingness to approach emotional situations, resulted in more lenient sentences for defendants. An overarching and as yet unanswered validity concern regarding this line of research in general is whether the use of undergraduate mock jurors reliably models real jurors in actual courtroom settings.

Competency to stand trial among female inpatients.

2013-08-01

Competency to stand trial evaluations are conducted by forensic mental health professionals to opine whether defendants possess the mental abilities to understand, appreciate, and reason in regard to their court proceedings. The majority of research on competency to stand trial evaluations has focused on males, with research on female defendants being relatively underexplored. Even less is known of diverse female samples referred for competency evaluation. In the current study, we sought to examine whether characteristics associated with competency among predominantly male samples translate to a racially, ethnically, and culturally diverse group of female defendants (N = 288, 85% non-White). Chi-square analyses revealed significant relationships between findings of incompetence and defendants' diagnosis of a psychotic disorder, active psychotic symptoms, medication noncompliance, nonparticipation in the evaluation, and nonfelony charges. Logistic regression analysis indicated that defendants who experienced active psychotic symptoms, did not participate in their evaluations, and were not compliant with their medication were most likely to be found incompetent. Notably, neither minority status nor age was a significant characteristic in predicting incompetence. These findings in particular differ from much of the literature and highlight the need to examine competency within a cross-cultural framework, as characteristics associated with competency opinions do not necessarily translate across demographic groups.

Jones, Elaine C; Evans, David A

2015-04-01

Changes in health care are having a dramatic effect on the practice of medicine. In 2005, a National Center for Health Statistics survey showed that 55%-70% of physicians are in small/solo practices. These data also demonstrated that 70% of physicians identified themselves as owners. Since passage of the Affordable Care Act (ACA) in 2010, neurologists report an 8% increase in academic practice settings, a 2% decrease in private practice settings, and a 5% decrease in solo practice settings. Surveys of family physicians showed that 60% are now employees of hospitals or larger groups. A survey by The Physicians Foundation showed that 89% of physicians believed that the traditional model of independent private practice is either "on shaky ground" or "a dinosaur soon to go extinct." With the changes expected from the ACA, solo/small practices will continue to face challenges and therefore must pay close attention to business and clinical metrics.

Defending the beauty of the Invariance Principle

NASA Astrophysics Data System (ADS)

Barkana, Itzhak

2014-01-01

Customary stability analysis methods for nonlinear nonautonomous systems seem to require a strict condition of uniform continuity. Although extensions of LaSalle's Invariance Principle to nonautonomous systems that mitigate this condition have been available for a long time, they have remained surprisingly unknown or open to misinterpretations. The large scope of the Principle might have misled the prospective users and its application to Control problems has been received with amazing yet clear uneasiness. Counterexamples have been used in order to claim that the Invariance Principle cannot be applied to nonlinear nonautonomous systems. Because the original formulation of the Invariance Principle still imposes conditions that are not necessarily needed, this paper presents a new Invariance Principle that further mitigates previous conditions and thus further expands the scope of stability analysis. A brief comparative review of various alternatives to stability analysis of nonautonomous nonlinear systems and their implications is also presented in order to illustrate that thorough analysis of same examples may actually confirm the efficiency of the Invariance Principle approach when dealing with stability of nonautonomous nonlinear systems problems that may look difficult or even unsolvable otherwise.

Smallpox has shaped human history, from the earliest human civilizations well into the 20th century. With high mortality rates, rapid transmission, and serious long-term effects on survivors, smallpox was a much-feared disease. The eradication of smallpox represents an unprecedented medical victory for the lasting benefit of human health and prosperity. Concerns remain, however, about the development and use of the smallpox virus as a biological weapon, which necessitates the need for continued vaccine development.

Defending networks against denial-of-service attacks

NASA Astrophysics Data System (ADS)

Gelenbe, Erol; Gellman, Michael; Loukas, George

2004-11-01

Denial of service attacks, viruses and worms are common tools for malicious adversarial behavior in networks. Experience shows that over the last few years several of these techniques have probably been used by governments to impair the Internet communications of various entities, and we can expect that these and other information warfare tools will be used increasingly as part of hostile behavior either independently, or in conjunction with other forms of attack in conventional or asymmetric warfare, as well as in other forms of malicious behavior. In this paper we concentrate on Distributed Denial of Service Attacks (DDoS) where one or more attackers generate flooding traffic and direct it from multiple sources towards a set of selected nodes or IP addresses in the Internet. We first briefly survey the literature on the subject, and discuss some examples of DDoS incidents. We then present a technique that can be used for DDoS protection based on creating islands of protection around a critical information infrastructure. This technique, that we call the CPN-DoS-DT (Cognitive Packet Networks DoS Defence Technique), creates a self-monitoring sub-network surrounding each critical infrastructure node. CPN-DoS-DT is triggered by a DDoS detection scheme, and generates control traffic from the objects of the DDoS attack to the islands of protection where DDOS packet flows are destroyed before they reach the critical infrastructure. We use mathematical modelling, simulation and experiments on our test-bed to show the positive and negative outcomes that may result from both the attack, and the CPN-DoS-DT protection mechanism, due to imperfect detection and false alarms.

Eosinophils in helminth infection: defenders and dupes

PubMed Central

Huang, Lu; Appleton, Judith A.

2016-01-01

Eosinophilia is a central feature of the host response to helminth infection. Larval stages of parasitic worms are killed in vitro by eosinophils in the presence of specific antibodies or complement. These findings established host defense as the paradigm for eosinophil function. Recently, studies in eosinophil-ablated mouse strains have revealed an expanded repertoire of immunoregulatory functions for this cell. Other reports document crucial roles for eosinophils in tissue homeostasis and metabolism, processes that are central to the establishment and maintenance of parasitic worms in their hosts. In this review, we summarize current understanding of the significance of eosinophils at the host-parasite interface, highlighting their distinct functions during primary and secondary exposure.

Deconstructing design: a strategy for defending science.

PubMed

Miller, K R

2009-01-01

Despite its legal and scientific failings, the "intelligent design" (ID) movement has been a public relations success story in the United States. By first creating doubts about the adequacy of evolution to account for the complexity of life, the ID movement has invoked the values of "fairness" and "openness" to argue for inclusion in the classroom and curriculum. In this way, it has attempted to lay claim to the very principles of critical analysis and open discussion at the heart of the scientific enterprise, leaving many researchers in doubt as to how to respond to these challenges. Specific case studies, including the blood-clotting cascade and data from the human genome, show how scientists can have a leading role in deconstructing the arguments advanced in favor of ID. The key to this strategy is remarkably simple and was at the heart of the landmark 2005 Kitzmiller v. Dover trial on ID. It is for researchers to take the claims made by ID proponents seriously, and then to follow them to their logical scientific conclusions. When this is done effectively, the hypothesis of "design" can be publicly falsified in ways that are understandable to laypeople and decision makers in education.

The "general recognition and acceptance" standard of objectivity for good faith in prescribing: legal and medical implications.

PubMed

Brushwood, David B

2007-01-01

The United States Court of Appeals for the 4th Circuit has ruled that a jury considering charges of drug trafficking against a pain management physician should be instructed that the defendant's good faith is a defense to the charges. The court rejected a subjective standard of good faith, and instead ruled that the good faith of the defendant must be evaluated from an objective perspective. This objective standard requires that the jury determine whether the defendant was practicing in accordance with the standard generally recognized and accepted in the United States. General recognition and acceptance are determined on a case-by-case basis, within the context of a defendant's practice. Simply because a physician's practice is out of the norm for many physicians does not mean it can't be generally recognized and accepted within the standard of medical practice. Expert witness testimony of pain management physicians will assist juries in the application of this standard for good faith in prescribing.

Deciding the fate of others: the cognitive underpinnings of racially biased juror decision making.

PubMed

Kleider, Heather M; Knuycky, Leslie R; Cavrak, Sarah E

2012-01-01

In criminal law, jurors are supposed to ignore defendant race when considering factual matters of culpability. However, when judging the merits of a criminal case, jurors' ability (or inability) to avoid bias may affect verdicts. Fact-based decision making expend cognitive resources, while heuristic-based decisions (e.g., using criminal stereotypes) conserve resources. Here, we investigated whether differences in cognitive resources and prejudice attitudes about Blacks influenced trial outcomes. We tested the impact of working memory capacity (WMC), cognitive load, prejudice, and target race (Black, White) on penalties ascribed to fictional criminal defendants in ambiguous-fact cases. Results showed that when "loaded," prejudiced-low-WMC persons supported guilty verdicts with higher confidence more often for Black than White defendants. Conversely, regardless of WMC or prejudice attitude, participants penalized White defendants more often when not loaded. We suggest that cognitive resources and prejudice attitude influence fact-based decisions. Links to juror judgments and potential trial outcomes are discussed.

Maternal investment plays a critical role in neonate survival, and adults can improve survival of offspring by defending them against predators. However, limited information exists documenting ungulate aggression toward humans in defense of neonates. During captures of neonates in spring 2007 and 2008 in north-central South Dakota, we documented 24 aggressive encounters by adult female and yearling male and female white-tailed deer (Odocoileus virginianus) defending neonates. Eleven (45.8%) aggressive encounters included yearlings accompanying adult females. Mean ages and weights of neonates that were aggressively defended were greater (P < 0.0001) than ages and weights of those that were not; adults began protecting neonates at approximately 4 days of age. Male fawns were more likely (P = 0.013) to be defended than female fawns. Examination of our data suggests that sex- and age-biased maternal defensive behavior exists in white-tailed deer, and that deer biased maternal investment toward older, male neonates.

Data were examined from an archival sample of Competency to Stand Trial (CST) reports of 200 consecutive New York City pre-trial defendants evaluated over a five-month period. Approximately a fourth of defendants in the present study were immigrants; many required the assistance of interpreters. The examiners conducting the CST evaluation diagnosed approximately half of the defendants with a primary diagnosis of a psychotic disorder and deemed over half not competent. Examiners reached the same conclusion about competency in 96% of cases, about the presence of a psychotic disorder in 91% of cases, and affective disorder in 85% of cases. No significant differences between psychologists and psychiatrists were found for rates of competency/incompetency opinions. Compared to those deemed competent, defendants deemed not competent had significantly higher rates of prior psychiatric hospitalization and diagnosis of psychotic illness at the time of the CST evaluation but lower rates of reported substance abuse.

Culture in the Courtroom: Ethnocentrism and Juror Decision-Making

PubMed Central

Maeder, Evelyn M.; Yamamoto, Susan

2015-01-01

The purpose of this study was to investigate whether a culturally-based argument in a non-insane automatism defense would be detrimental or beneficial to the defendant. We also examined how juror ethnocentrism might affect perceptions of such a defense. Participants read a fictional filicide homicide case in which the defendant claimed to have blacked out during the crime; we manipulated whether culture was used as an explanation for what precipitated the defendant’s blackout. We conducted path analyses to assess the role of ethnocentrism in predicting lower defendant credibility, and harsher verdict decisions. Results revealed an interaction between ethnocentrism and defense type, such that ethnocentrism related to lower perceived defendant credibility in the cultural condition, but not in the standard automatism condition. This study marks a starting point for empirically investigating the role of culture in the courtroom, which may aid scholars in discussing the merits of a standalone cultural defense. PMID:26353122

Effects of state organizational structure and forensic examiner training on pretrial competence assessments.

Edens, J F; Poythress, N G; Nicholson, R A; Otto, R K

1999-05-01

States differ widely in their delivery of pretrial forensic evaluation services, in terms of organizational structure and training requirements of forensic examiners. It was hypothesized that defendants adjudicated incompetent to proceed in states using community-based, private-practitioner systems would show less impairment on a competence assessment measure, the MacArthur Competence Assessment Tool-Criminal Adjudication (MacCAT-CA), than defendants adjudicated incompetent in states using traditional, inpatient systems. It also was hypothesized that mean MacCAT-CA scores for incompetent defendants from states requiring forensic training/certification would be lower than for defendants from states lacking such requirements. Results indicated significant differences across the four types of service delivery systems examined. However, planned comparisons revealed no differences between a state using a traditional, inpatient model and a state employing a community-based, private-practitioner model. Analyses examining the effects of mandatory forensic training failed to support the hypothesis that training requirements result in the adoption of higher thresholds for determining incompetence.

Modular Stirling Radioisotope Generator

NASA Technical Reports Server (NTRS)

Schmitz, Paul C.; Mason, Lee S.; Schifer, Nicholas A.

2015-01-01

High efficiency radioisotope power generators will play an important role in future NASA space exploration missions. Stirling Radioisotope Generators (SRG) have been identified as a candidate generator technology capable of providing mission designers with an efficient, high specific power electrical generator. SRGs high conversion efficiency has the potential to extend the limited Pu-238 supply when compared with current Radioisotope Thermoelectric Generators (RTG). Due to budgetary constraints, the Advanced Stirling Radioisotope Generator (ASRG) was canceled in the fall of 2013. Over the past year a joint study by NASA and DOE called the Nuclear Power Assessment Study (NPAS) recommended that Stirling technologies continue to be explored. During the mission studies of the NPAS, spare SRGs were sometimes required to meet mission power system reliability requirements. This led to an additional mass penalty and increased isotope consumption levied on certain SRG-based missions. In an attempt to remove the spare power system, a new generator architecture is considered which could increase the reliability of a Stirling generator and provide a more fault-tolerant power system. This new generator called the Modular Stirling Radioisotope Generator (MSRG) employs multiple parallel Stirling convertor/controller strings, all of which share the heat from the General Purpose Heat Source (GPHS) modules. For this design, generators utilizing one to eight GPHS modules were analyzed, which provide about 50 to 450 watts DC to the spacecraft, respectively. Four Stirling convertors are arranged around each GPHS module resulting in from 4 to 32 Stirling/controller strings. The convertors are balanced either individually or in pairs, and are radiatively coupled to the GPHS modules. Heat is rejected through the housing/radiator which is similar in construction to the ASRG. Mass and power analysis for these systems indicate that specific power may be slightly lower than the ASRG and

The Department of Energy, Stirling Technology Company (STC), and NASA Glenn Research Center (GRC) are developing a free-piston Stirling convertor for a high-efficiency Stirling Radioisotope Generator (SRG) for NASA Space Science missions. The SRG is being developed for multimission use, including providing electric power for unmanned Mars rovers and deep space missions. NASA GRC is conducting an in-house technology project to assist in developing the convertor for space qualification and mission implementation. Recent testing of 55-We Technology Demonstration Convertors (TDC's) built by STC includes mapping of a second pair of TDC's, single TDC testing, and TDC electromagnetic interference and electromagnetic compatibility characterization on a non-magnetic test stand. Launch environment tests of a single TDC without its pressure vessel to better understand the convertor internal structural dynamics and of dual-opposed TDC's with several engineering mounting structures with different natural frequencies have recently been completed. A preliminary life assessment has been completed for the TDC heater head, and creep testing of the IN718 material to be used for the flight convertors is underway. Long-term magnet aging tests are continuing to characterize any potential aging in the strength or demagnetization resistance of the magnets used in the linear alternator (LA). Evaluations are now beginning on key organic materials used in the LA and piston/rod surface coatings. GRC is also conducting finite element analyses for the LA, in part to look at the demagnetization margin on the permanent magnets.

NASA's RPS Design Reference Mission Set for Solar System Exploration

NASA Technical Reports Server (NTRS)

Balint, Tibor S.

2007-01-01

NASA's 2006 Solar System Exploration (SSE) Strategic Roadmap identified a set of proposed large Flagship, medium New Frontiers and small Discovery class missions, addressing key exploration objectives. These objectives respond to the recommendations by the National Research Council (NRC), reported in the SSE Decadal Survey. The SSE Roadmap is down-selected from an over-subscribed set of missions, called the SSE Design Reference Mission (DRM) set. Missions in the Flagship and New Frontiers classes can consider Radioisotope Power Systems (RPSs), while small Discovery class missions are not permitted to use them, due to cost constraints. In line with the SSE DRM set and the SSE Roadmap missions, the RPS DRM set represents a set of missions, which can be enabled or enhanced by RPS technologies. At present, NASA has proposed the development of two new types of RPSs. These are the Multi-Mission Radioisotope Thermoelectric Generator (MMRTG), with static power conversion; and the Stirling Radioisotope Generator (SRG), with dynamic conversion. Advanced RPSs, under consideration for possible development, aim to increase specific power levels. In effect, this would either increase electric power generation for the same amount of fuel, or reduce fuel requirements for the same power output, compared to the proposed MMRTG or SRG. Operating environments could also influence the design, such that an RPS on the proposed Titan Explorer would use smaller fins to minimize heat rejection in the extreme cold environment; while the Venus Mobile Explorer long-lived in-situ mission would require the development of a new RPS, in order to tolerate the extreme hot environment, and to simultaneously provide active cooling to the payload and other electric components. This paper discusses NASA's SSE RPS DRM set, in line with the SSE DRM set. It gives a qualitative assessment regarding the impact of various RPS technology and configuration options on potential mission architectures, which could

Combined evaluations of competency to stand trial and mental state at the time of the offense: An overlooked methodological consideration?

PubMed

Kois, Lauren; Wellbeloved-Stone, James M; Chauhan, Preeti; Warren, Janet I

2017-06-01

Combined evaluations of competency to stand trial (CST; competency) and mental state at the time of the offense (MSO; sanity) frequently co-occur. However, most research examines the 2 as discrete constructs without considering 4 potential combined evaluation outcomes: competent-sane, incompetent-sane, competent-insane, and incompetent-insane. External validity can be improved if research more closely mirrored practice. It may be incorrect to assume incompetent defendants are similar across CST-only and combined evaluations, and insane defendants are similar across MSO-only and combined evaluations. Using a sample of 2,751 combined evaluations, we examined demographic, clinical, offense, evaluation, and psycholegal characteristics associated with evaluators' combined evaluation opinions. Multinomial regression analyses revealed older defendants were more likely to be opined incompetent-insane. Defendants with psychotic disorders were more often opined insane, regardless of competency status. Affective diagnoses predicted competent-insane opinions. Developmental disorders were closely related to incompetence, regardless of sanity status. Defendants with organic disorders tended to have global psycholegal impairment, in that they were more often opined incompetent-insane, incompetent-sane, or competent-insane, relative to competent-sane. Prior hospitalization predicted competent-insane relative to competent-sane opinions. Defendants not under the influence of a substance during the offense or with no prior convictions were more likely to be opined insane, regardless of competency status. We interpret these findings in light of psycholegal theory and provide recommendations for research and practice. Collectively, results suggest incorporation of combined evaluations into CST and MSO research is an important methodological consideration not to be overlooked.

The importance of ecological costs for the evolution of plant defense against herbivory.

PubMed

van Velzen, Ellen; Etienne, Rampal S

2015-05-07

Plant defense against herbivory comes at a cost, which can be either direct (reducing resources available for growth and reproduction) or indirect (through reducing ecological performance, for example intraspecific competitiveness). While direct costs have been well studied in theoretical models, ecological costs have received almost no attention. In this study we compare models with a direct trade-off (reduced growth rate) to models with an ecological trade-off (reduced competitive ability), using a combination of adaptive dynamics and simulations. In addition, we study the dependence of the level of defense that can evolve on the type of defense (directly by reducing consumption, or indirectly by inducing herbivore mortality (toxicity)), and on the type of herbivore against which the plant is defending itself (generalists or specialists). We find three major results: First, for both direct and ecological costs, defense only evolves if the benefit to the plant is direct (through reducing consumption). Second, the type of cost has a major effect on the evolutionary dynamics: direct costs always lead to a single optimal strategy against herbivores, but ecological costs can lead to branching and the coexistence of non-defending and defending plants; however, coexistence is only possible when defending against generalist herbivores. Finally, we find that fast-growing plants invest less than slow-growing plants when defending against generalist herbivores, as predicted by the Resource Availability Hypothesis, but invest more than slow-growing plants when defending against specialists. Our results clearly show that assumptions about ecological interactions are crucial for understanding the evolution of defense against herbivores. Copyright © 2015 Elsevier Ltd. All rights reserved.

Sex and race as factors affecting the attribution of insanity in a murder trial.

McGlynn, R P; Megas, J C; Benson, D H

1976-05-01

Two hundred and eight white male and female college students read a summary of a case of a violent murder in which an insanity plea was entered. The sex and race (black or white) of the hypothetical defendant was varied in a 2 X 2 factorial design with 52 Ss per cell. Measurements included verdict (guilty or insane), length of recommended sentence, and ratings of certain defendant characteristics. Major results were as follows: (a) harsher treatment of males as indicated by longer sentences, (b) longer sentences for white as opposed to black males among defendants found guilty, and (c) a trend toward a higher proportion of guilty verdicts for black males.

An indoor air quality-pharmacokinetic simulation of passive inhalation of marijuana smoke and the resultant buildup of 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid in urine.

PubMed

Giardino, N J

1997-03-01

In military courts of law, the good soldier defense is often used by the defendant to explain the presence of 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid in urine (hereafter referred to as THCA) above the Department of Defense (DOD) established limit of 15 ng/mL. The defense will contend the defendant unwittingly breathed side-stream marijuana smoke, thus resulting in the presence of THCA in the defendant's urine. The purpose of this work was to link an indoor air quality model (IAQ) with a pharmacokinetic (PK) model to predict a passive marijuana smoker's resultant concentration of the major urinary metabolite THCA.

2006-01-01

Background In the late 1990s and the early part of this decade, the major US cigarette manufacturers admitted, to varying degrees, that smoking causes cancer and other diseases. Objective To examine how tobacco manufacturers have defended themselves against charges that their products caused cancer in plaintiffs in 34 personal injury lawsuits, all but one of which were litigated between the years 1986 and 2003. Methods Defence opening and closing statements, trial testimony, and depositions for these cases were obtained from the Tobacco Deposition and Trial Testimony Archive (http://tobaccodocuments.org/datta/). All available defence‐related transcripts from these cases were reviewed and a content analysis was conducted to identify common themes in the defendants' arguments. Results After review of the transcripts, defendants' arguments were grouped into seven categories: (1) there is no scientific proof that cigarette smoking causes lung cancer; (2) the plaintiff did not have lung cancer as claimed; (3) the plaintiff had a type of lung cancer not associated with cigarette smoking; (4) the plaintiff had cancer that may have been associated with cigarette smoking or smokeless tobacco use, but tobacco products were not to blame in this particular case; (5) the plaintiff had cancer that may have been associated with cigarette smoking, but the defendant's cigarette brands were not to blame; (6) the defendant's cigarettes (or smokeless tobacco) may have played a role in the plaintiff's illness/death, but other risk factors were present that negate or mitigate the defendant's responsibility; and (7) the defendant's cigarettes may have been a factor in the plaintiff's illness/death, but the plaintiff knew of the health risks and exercised free will in choosing to smoke and declining to quit. Use of the argument that smoking is not a proven cause of lung cancer declined in frequency during and after the period when tobacco companies began to publicly admit that smoking

This study investigates the financial burden of medical malpractice litigation associated with rhytidectomies, as well as factors that contribute to litigation and poor defendant outcomes, which can help guide physician practices. To comprehensively evaluate rhytidectomy malpractice litigation. Jury verdict and settlement reports related to rhytidectomy malpractice litigations were obtained using the Westlaw Next database. Use of medical malpractice in conjunction with several terms for rhytidectomy, to account for the various procedure names associated with the procedure, yielded 155 court cases. Duplicate and nonrelevant cases were removed, and 89 cases were included in the analysis and reviewed for outcomes, defendant specialty, payments, and other allegations raised in proceedings. Data were collected from November 21, 2015, to December 25, 2015. Data analysis took place from December 25, 2015, to January 20, 2016. A total of 89 cases met our inclusion criteria. Most plaintiffs were female (81 of 88 with known sex [92%]), and patient age ranged from 40 to 76 years (median age, 56 years). Fifty-three (60%) were resolved in the defendant's favor, while the remaining 36 cases (40%) were resolved with either a settlement or a plaintiff verdict payment. The mean payment was $1.4 million. A greater proportion of cases involving plastic surgeon defendants were resolved with payment compared with cases involving defendants with ear, nose, and throat specialty (15 [36%] vs 4 [24%]). The most common allegations raised in litigation were intraoperative negligence (61 [69%]), poor cosmesis or disfigurement (57 [64%]), inadequate informed consent (30 [34%]), additional procedures required (14 [16%]), postoperative negligence (12 [14%]), and facial nerve injury (10 [11%]). Six cases (7%) involved alleged negligence surrounding a "lifestyle-lift" procedure, which tightens or oversews the superficial muscular aponeurosis system layer. In this study, although most cases of

This study examined the effects of manipulating relative positioning between defenders (initial distance apart) on emergent decision-making and actions in a 1 vs. 2 rugby union performance sub-phase. Twelve experienced youth players performed 80 trials of a 1 (attacker) vs. 2 (defenders) practice task in which the starting distance between defenders was systematically decreased. Movement displacement trajectories of participants were video recorded to obtain 2D positional data. The independent variable was the starting distance between defenders and dependent variables were: (i) performance outcome (try or tackle), (ii) mean speed of all players during performance, and (iii), time between the first crossover and the end of the trial. Repeated measures ANOVA was used to compare the effects of different starting distances on performance. Shorter starting distances between defenders were associated with a higher frequency of effective tackle outcomes, lower mean speeds of all participants, and a greater time period between the first crossover and the end of the trial. Decision-making behaviours emerged as a function of changes in participants' spatial location during performance. This observation supports the importance of manipulating key spatial-temporal variables in designing representative practice task constraints that induce functional player-environment interactions in team sports training.

Sleep-Related Violence and Sexual Behavior in Sleep: A Systematic Review of Medical-Legal Case Reports

PubMed Central

Ingravallo, Francesca; Poli, Francesca; Gilmore, Emma V.; Pizza, Fabio; Vignatelli, Luca; Schenck, Carlos H.; Plazzi, Giuseppe

2014-01-01

Objective: To review systematically medical-legal cases of sleep-related violence (SRV) and sexual behavior in sleep (SBS). Search Methods: We searched Pubmed and PsychINFO (from 1980 to 2012) with pre-specified terms. We also searched reference lists of relevant articles. Selection Criteria: Case reports in which a sleep disorder was purported as the defense during a criminal trial and in which information about the forensic evaluation of the defendant was provided. Data Extraction and Analysis: Information about legal issues, defendant and victim characteristics, circumstantial factors, and forensic evaluation was extracted from each case. A qualitative-comparative assessment of cases was performed. Results: Eighteen cases (9 SRV and 9 SBS) were included. The charge was murder or attempted murder in all SRV cases, while in SBS cases the charge ranged from sexual touching to rape. The defense was based on sleepwalking in 11 of 18 cases. The trial outcome was in favor of the defendant in 14 of 18 cases. Defendants were relatively young males in all cases. Victims were usually adult relatives of the defendants in SRV cases and unrelated young girls or adolescents in SBS cases. In most cases the criminal events occurred 1-2 hours after the defendant's sleep onset, and both proximity and other potential triggering factors were reported. The forensic evaluations widely differed from case to case. Conclusion: SRV and SBS medical-legal cases did not show apparent differences, except for the severity of the charges and the victim characteristics. An international multidisciplinary consensus for the forensic evaluation of SRV and SBS should be developed as an urgent priority.

Dissociative identity disorder: Medicolegal challenges.

PubMed

Farrell, Helen M

2011-01-01

Persons with dissociative identity disorder (DID) often present in the criminal justice system rather than the mental health system and perplex experts in both professions. DID is a controversial diagnosis with important medicolegal implications. Defendants have claimed that they committed serious crimes, including rape or murder, while they were in a dissociated state. Asserting that their alter personality committed the bad act, defendants have pleaded not guilty by reason of insanity (NGRI). In such instances, forensic experts are asked to assess the defendant for DID and provide testimony in court. Debate continues over whether DID truly exists, whether expert testimony should be allowed into evidence, and whether it should exculpate defendants for their criminal acts. This article reviews historical and theoretical perspectives on DID, presents cases that illustrate the legal implications and controversies of raising an insanity defense based on multiple personalities, and examines the role of forensic experts asked to comment on DID with the goal of assisting clinicians in the medicolegal assessment of DID in relation to crimes.

Determining criminal responsibility: How relevant are insight and personal attitudes to mock jurors?

PubMed

Jung, Sandy

2015-01-01

High levels of insight are interpreted as indications of a treatment compliance and good outcome by clinical professionals. However, it is unclear whether a defendant's insight plays a role in the decision-making of jurors when determining criminal responsibility. It may be the case that personal biases and attitudes toward the mentally ill and the insanity defense are more relevant in such decisions. This study examines the influence of two core dimensions of insight and personal attitudes on juror decision-making. Participants read trial scenarios describing a defendant who is accused of a violent crime and is diagnosed with schizophrenia. Assigning a verdict of not criminally responsible to the defendant was not influenced by insight, but instead, by supportive attitudes of the insanity defense and higher attributions of blame to external factors and to psychological factors. These findings highlight the need for continued investigation in the area of extra-legal factors that guide legal decision-making when defendants have a mental disorder.

Robust allocation of a defensive budget considering an attacker's private information.

PubMed

Nikoofal, Mohammad E; Zhuang, Jun

2012-05-01

Attackers' private information is one of the main issues in defensive resource allocation games in homeland security. The outcome of a defense resource allocation decision critically depends on the accuracy of estimations about the attacker's attributes. However, terrorists' goals may be unknown to the defender, necessitating robust decisions by the defender. This article develops a robust-optimization game-theoretical model for identifying optimal defense resource allocation strategies for a rational defender facing a strategic attacker while the attacker's valuation of targets, being the most critical attribute of the attacker, is unknown but belongs to bounded distribution-free intervals. To our best knowledge, no previous research has applied robust optimization in homeland security resource allocation when uncertainty is defined in bounded distribution-free intervals. The key features of our model include (1) modeling uncertainty in attackers' attributes, where uncertainty is characterized by bounded intervals; (2) finding the robust-optimization equilibrium for the defender using concepts dealing with budget of uncertainty and price of robustness; and (3) applying the proposed model to real data. © 2011 Society for Risk Analysis.

Investigating Miranda waiver decisions: An examination of the rational consequences.

PubMed

Blackwood, Hayley L; Rogers, Richard; Steadham, Jennifer A; Fiduccia, Chelsea E

2015-01-01

Millions of custodial suspects waive their Miranda rights each year without the benefit of legal counsel. Miranda understanding, appreciation, and reasoning abilities are essential to courts' acceptance of Miranda waivers (Grisso, 2003; Rogers & Shuman, 2005). The question posed to forensic psychologists and psychiatrists in the disputed Miranda waivers is whether a particular waiver decision was knowing, intelligent, and voluntary. Despite the remarkable development of Miranda research in recent decades, studies have generally focused on understanding and appreciation of Miranda rights, but with comparatively minimal emphasis on Miranda reasoning and attendant waiver decisions. Research on defendants' decisional capacities constitutes a critical step in further developing theoretical and clinical models for Miranda waiver decisions. The current study evaluated Miranda waiver decisions for 80 pretrial defendants from two Oklahoma jails to study systematically how rational decision abilities affect defendants' personal waiver decisions. In stark contrast to what was expected, many defendants were able to identify a rational decisional process in their own legal cases, yet cast such reasoning aside and chose a completely contradictory Miranda waiver decision.

Canadian mock juror attitudes and decisions in domestic violence cases involving asian and white interracial and intraracial couples.

PubMed

Maeder, Evelyn M; Mossière, Annik; Cheung, Liann

2013-03-01

This study manipulated the race of the defendant and the victim (White/White, White/Asian, Asian/Asian, and Asian/White) in a domestic violence case to examine the potential prejudicial impact of race on juror decision making. A total of 181 undergraduate students read a trial transcript involving an allegation of spousal abuse in which defendant and victim race were manipulated using photographs. They then provided a verdict and confidence rating, a sentence, and responsibility attributions, and completed various scales measuring attitudes toward wife abuse and women. Findings revealed that female jurors were harsher toward the defendant than were male jurors. When controlling for attitudes toward Asians, jurors found the defendant guilty more often in cases involving interracial couples, as compared to same-race couples. Path analyses revealed various factors and attitudes involved in domestic violence trial outcomes. Findings contribute to the scarce literature on legal proceedings involving Asians, particularly in domestic violence cases. Outcomes also provide a model for relevant factors and characteristics of jurors in domestic violence cases. Roadblocks inherent in jury research are also discussed.

Carney v Newton: expert evidence about the standard of clinical notes.

PubMed

Faunce, Thomas; Hammer, Ingrid; Jefferys, Susannah

2007-12-01

In Carney v Newton [2006] TASSC 4 the Tasmanian Supreme Court heard a claim that the defendant breached his duty of care by failing to properly diagnose and treat a node positive carcinoma in the plaintiff's breast tissue. At trial, argument turned on the actual dialogue that took place during the initial consultation, with significant reliance on the clinical notes of the defendant. The court gave considerable weight to "expert" witnesses in ascertaining the acceptability of the defendant's conduct concerning the maintenance and interpretation of his clinical notes. This raises important questions in relation to proof of quality of medical records as part of the current professional standard of care, as modified by recent legislation in most jurisdictions.

Melvin v. Kim's Restaurant, Inc. [13 July 1989].

PubMed

1989-01-01

In Oregon, after her dismissal by the defendant, the plaintiff, a waitress employed by the defendant, brought a suit charging discrimination on the basis of handicap. She claimed that she had been dismissed because the defendant regarded her pregnancy as a physical impairment. The court allowed the suit to proceed, ruling that discrimination on the basis of pregnancy could constitute handicap discrimination. On 8 June 1989 the United States Court of Appeals, Ninth Circuit, held that consideration of the petitioner's pregnancy in deciding whether her case should be heard in the juvenile court did not constitute sex discrimination in violation of equal protection rights (Toomey v. Clark, 876 F.2d 1433).

Is courtship intensity a signal of male parental care in Red-winged Blackbirds (Agelaius phoeniceus)?

USGS Publications Warehouse

Yasukawa, Ken; Knight, Richard L.; Skagen, Susan Knight

1987-01-01

We studied Red-winged Blackbird (Agelaius phoeniceus) behavior in marsh and prairie habitats to determine whether courting males provide cues of their nest defense, whether females prefer males that defend nests vigorously, and whether male nest defense affects nest success. We found no evidence that courtship behavior provides cues of male nest defense, or that females prefer males that court intensely. We found evidence that females nesting in marshes prefer males that defend nests intensely, but no evidence that intensely defending males in the prairie habitat achieve high nest success. We found differences, however, between marsh and prairie habitats that suggest a coarse-grained relationship between male parental quality and female choice of mate in this species.
