Coherent Excitation of Heterosymmetric Spin Waves with Ultrashort Wavelengths

In the emerging field of magnonics, spin waves are foreseen as signal carriers for future spintronic information processing and communication devices, owing to both the very low power losses and a high device miniaturization potential predicted for short-wavelength spin waves. Yet, the efficient excitation and controlled propagation of nanoscale spin waves remains a severe challenge. Here, we report the observation of high-amplitude, ultrashort dipole-exchange spin waves (down to 80 nm wavelength at 10 GHz frequency) in a ferromagnetic single layer system, coherently excited by the driven dynamics of a spin vortex core. We used time-resolved x-ray microscopy to directly image such propagating spin waves and their excitation over a wide range of frequencies. By further analysis, we found that these waves exhibit a heterosymmetric mode profile, involving regions with anti-Larmor precession sense and purely linear magnetic oscillation. In particular, this mode profile consists of dynamic vortices with laterally alternating helicity, leading to a partial magnetic flux closure over the film thickness, which is explained by a strong and unexpected mode hybridization. This spin-wave phenomenon observed is a general effect inherent to the dynamics of sufficiently thick ferromagnetic single layer films, independent of the specific excitation method employed.

Relationships between narcissistic grandiosity, narcissistic vulnerability, regulatory focus, regulatory mode, and life-satisfaction: Data from two surveys

The present data is reported in the article "Regulatory Focus and Regulatory Mode - Keys to Narcissists' (Lack of) Life Satisfaction?" (Hanke et al., in press) [1]. The two data sets represent answers from two German samples. Data were collected via self-report questionnaires using EFS survey from QuestBack Unipark. The surveys included self-questionnaires of narcissistic grandiosity, narcissistic vulnerability, regulatory focus, regulatory mode, self-esteem, life-satisfaction, and demographic information.

Materialists on Facebook: the self-regulatory role of social comparisons and the objectification of Facebook friends

In this study, we examine chronic materialism as a possible motive for Facebook usage. We test an explanatory mediation model predicting that materialists use Facebook more frequently, because they compare themselves to others, they objectify and instrumentalize others, and they accumulate friends. For this, we conducted two online surveys (N₁ = 242, N₂ = 289) assessing demographic variables, Facebook use, social comparison, materialism, objectification and instrumentalization. Results confirm the predicted mediation model. Our findings suggest that Facebook can be used as a means to an end in a way of self-regulatory processes, like satisfying of materialistic goals. The findings are the first evidence for our Social Online Self-regulation Theory (SOS-T), which contains numerous predictions that can be tested in the future.

Improvement of lay rescuer chest compressions with a novel audiovisual feedback device : A randomized trial

BACKGROUND

Bystander actions and skills determine among others the outcome of out-of-hospital cardiac arrest. However, the depth and rate of chest compressions (CC) are difficult to estimate for laypeople and poor CC quality may result. Our study aimed to evaluate the impact of a new feedback device on CC performance by laypeople. The percentage of CC with both correct rate and correct depth of all CC served as primary endpoint.

METHODS

Forty-eight subjects with no medical background performed 2 min of CC on a manikin with and without a novel feedback device (TrueCPR™, Physio-Control, Redmond, Wash.). The device uses a novel, non-accelerometer-based technology. Participants were randomized into two groups. Group 1 performed a 2-min CC trial first with audiovisual feedback followed by a trial with no feedback information, while group 2 performed the task in reverse order.

RESULTS

The absolute percentage of CC with correct rate and depth was significantly higher with the use of the device (59 ± 34% vs. 15 ± 21%, p < 0.0001). The longest interval without correct CC was significantly decreased (76.5 s vs. 27.5 s, p < 0.0001).

CONCLUSION

The quality of CC carried out by laypeople is significantly improved with the use of a new feedback device. The device may be useful for cardiopulmonary resuscitation (CPR) by laypeople and for educational purposes.

Self-Reflection and Recognition: The Role of Metacognitive Knowledge in the Attribution of Recollective Experience

We argue that to understand how a recognition task is solved, it is helpful to study the inferences that are drawn on the basis of psychological self-knowledge. This claim is supported by findings from 3 experiments in which participants' metacognitive knowledge was either measured or manipulated. Specifically, it was found that when the quality of a recollective experience was not associated with one particular cause, knowledge about whether one would have noted or remembered a stimulus is used. In conclusion, we argue that a perspective that is derived from attribution theory in social psychology may be fruitfully applied to phenomena of recognition.

[S2k-Guideline on Meniscus Diseases: from Aetiology to Scoring]

The number of patients with meniscal injuries is increasing constantly, but the treatment algorithms are undergoing continuous change. The effects of meniscal surgery, as well as the indications for the procedure, are currently a matter of heated debate. Various German speaking associations addressing topics related to the knee have joined forces to develop guidelines for the diagnosis, evaluation and therapy of meniscal lesions. The hope is that this first of two publications will shed light on some of the ongoing issues and offer guidance to health care professionals treating these patients.

Seven Principles of Goal Activation: A Systematic Approach to Distinguishing Goal Priming From Priming of Non-Goal Constructs

Countless studies have recently purported to demonstrate effects of goal priming; however, it is difficult to muster unambiguous support for the claims of these studies because of the lack of clear criteria for determining whether goals, as opposed to alternative varieties of mental representations, have indeed been activated. Therefore, the authors offer theoretical guidelines that may help distinguish between semantic, procedural, and goal priming. Seven principles that are hallmarks of self-regulatory processes are proposed: Goal-priming effects (a) involve value, (b) involve postattainment decrements in motivation, (c) involve gradients as a function of distance to the goal, (d) are proportional to the product of expectancy and value, (e) involve inhibition of conflicting goals, (f) involve self-control, and (g) are moderated by equifinality and multifinality. How these principles might help distinguish between automatic activation of goals and priming effects that do not involve goals is discussed.

[Long-term follow-up and patient satisfaction of squint surgery with adjustable sutures]

OBJECTIVE

Up to now, no long-term results about squint surgery with adjustable sutures have been published although it has been practiced using the current techniques since the 1970s. The aim of the study was to analyse patient satisfaction and objective findings and to compare the results to studies about squint surgery with adjustable as well as non-adjustable sutures.

METHODS

Patients who had had squint surgery with adjustable sutures more than 10 years ago were identified according to their surgical records. They were contacted and asked to fill in a questionnaire. The collective consisted in cases which appeared to be difficult in treatment, e.g., 52 % had undergone previous squint surgery.

RESULTS

We could analyse answered questionnaires of 113 patients (return rate 41.9 % of all contactable patients). In 34 patients (30 %) postoperative adjustment was actually performed, in the others the suture was only knotted. 89.4 % of patients either had no problems or did not remember the procedure of adjustment or knotting, respectively, the others had slight discomfort. There were no technical problems in surgery or adjustment. After an average period of 11 years, the satisfaction was very high. The reoperation rate was 7 %.

CONCLUSIONS

Squint surgery with adjustable sutures is a valuable tool in difficult strabismus cases with good long-term patient satisfaction without specific problems of surgery.

Detour to Arrive: Distancing in Service of Approach Goals

Although in most situations approaching desired end-states entails decreasing distance between oneself and an object, and avoiding undesired end-states increases such distance, in some cases distancing can also be a means to approach a given goal. We highlight examples involving responses to obstacles to achievement and self-control dilemmas, showing that motivational direction is not equivalent to the motivational strategy involved when people pursue their goals.

Impact of thearubigins on the estimation of total dietary flavonoids in the European Prospective Investigation into Cancer and Nutrition (EPIC) study

Thearubigins (TR) are polymeric flavanol-derived compounds formed during the fermentation of tea leaves. Comprising ∼70% of total polyphenols in black tea, TR may contribute majorly to its beneficial effects on health. To date, there is no appropriate food composition data on TR, although several studies have used data from the US Department of Agriculture (USDA) database to estimate TR intakes. We aimed to estimate dietary TR in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort and assess the impact of including TR or not in the calculation of the total dietary flavonoid intake. Dietary data were collected using a single standardized 24-h dietary recall interviewer-administered to 36 037 subjects aged 35-74 years. TR intakes were calculated using the USDA database. TR intakes ranged from 0.9 mg/day in men from Navarra and San Sebastian in Spain to 532.5 mg/day in men from UK general population. TR contributed <5% to the total flavonoid intake in Greece, Spain and Italy, whereas in the UK general population, TR comprised 48% of the total flavonoids. High heterogeneity in TR intake across the EPIC countries was observed. This study shows that total flavonoid intake may be greatly influenced by TR, particularly in high black tea-consuming countries. Further research on identification and quantification of TR is needed to get more accurate dietary TR estimations.

Dietary intakes and food sources of phytoestrogens in the European Prospective Investigation into Cancer and Nutrition (EPIC) 24-hour dietary recall cohort

BACKGROUND/OBJECTIVES

Phytoestrogens are estradiol-like natural compounds found in plants that have been associated with protective effects against chronic diseases, including some cancers, cardiovascular diseases and osteoporosis. The purpose of this study was to estimate the dietary intake of phytoestrogens, identify their food sources and their association with lifestyle factors in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.

SUBJECTS/METHODS

Single 24-hour dietary recalls were collected from 36,037 individuals from 10 European countries, aged 35-74 years using a standardized computerized interview programe (EPIC-Soft). An ad hoc food composition database on phytoestrogens (isoflavones, lignans, coumestans, enterolignans and equol) was compiled using data from available databases, in order to obtain and describe phytoestrogen intakes and their food sources across 27 redefined EPIC centres.

RESULTS

Mean total phytoestrogen intake was the highest in the UK health-conscious group (24.9 mg/day in men and 21.1 mg/day in women) whereas lowest in Greece (1.3 mg/day) in men and Spain-Granada (1.0 mg/day) in women. Northern European countries had higher intakes than southern countries. The main phytoestrogen contributors were isoflavones in both UK centres and lignans in the other EPIC cohorts. Age, body mass index, educational level, smoking status and physical activity were related to increased intakes of lignans, enterolignans and equol, but not to total phytoestrogen, isoflavone or coumestan intakes. In the UK cohorts, the major food sources of phytoestrogens were soy products. In the other EPIC cohorts the dietary sources were more distributed, among fruits, vegetables, soy products, cereal products, non-alcoholic and alcoholic beverages.

CONCLUSIONS

There was a high variability in the dietary intake of total and phytoestrogen subclasses and their food sources across European regions.

Stepping back to see the big picture: when obstacles elicit global processing

Can obstacles prompt people to look at the "big picture" and open up their minds? Do the cognitive effects of obstacles extend beyond the tasks with which they interfere? These questions were addressed in 6 studies involving both physical and nonphysical obstacles and different measures of global versus local processing styles. Perceptual scope increased after participants solved anagrams in the presence, rather than the absence, of an auditory obstacle (random words played in the background; Study 1), particularly among individuals low in volatility (i.e., those who are inclined to stay engaged and finish what they do; Study 4). It also increased immediately after participants encountered a physical obstacle while navigating a maze (Study 3A) and when compared with doing nothing (Study 3B). Conceptual scope increased after participants solved anagrams while hearing random numbers framed as an "obstacle to overcome" rather than a "distraction to ignore" (Study 2) and after participants navigated a maze with a physical obstacle, compared with a maze without a physical obstacle, but only when trait (Study 5) or state (Study 6) volatility was low. Results suggest that obstacles trigger an "if obstacle, then start global processing" response, primarily when people are inclined to stay engaged and finish ongoing activities. Implications for dealing with life's obstacles and related research are discussed.

GLOMOsys

GLOMOsys (the global vs. local processing model, a systems account) includes predictions about cognitive mechanisms (the how) and functionalities (the why) of two processing systems: one that processes information holistically and one that processes the parts. GLOMOsys suggests that global versus local perceptual processing carries over to other perceptual and conceptual tasks; it summarizes antecedents of global/local processing; and it proposes that global processing is functional for understanding the general meaning of novel events, whereas local processing supports encoding of details in familiar situations and when novel events are threatening.

Stepping Back While Staying Engaged

When do people respond to obstacles by mentally “stepping back” and taking a more distanced perspective? Manipulating obstacles to social goals, to personal goals, and in a computer game, three studies tested the hypothesis that people should increase psychological distance upon facing an obstacle primarily when distancing is relevant, that is, when the obstacle appears on their own path to a goal or when they are engaged and motivated to follow through with activities. As expected, participants who imagined a goal-relevant versus a goal-irrelevant obstacle indicated greater estimates for an unrelated spatial distance (Study 1). Moreover, chronically engaged participants provided smaller font size estimates after thinking about how to reach a personal goal with versus without an obstacle (Study 2), and participants primed with engagement indicated greater estimates for an unrelated spatial distance after navigating a maze with versus without an obstacle (Study 3). Implications for related research are discussed.

What Is Automatic Self-Regulation?

Based on Bargh’s (1994) principles of automaticity, and Förster, Liberman, and Friedman’s (2007) principles of automatic goal activation, we discuss recent findings suggesting automatic self-regulation. We found evidence that many self-regulatory strategies can be automatized, particularly goal activation outside of participants’ awareness, and procedures to inhibit accessibility of competing goals and to devalue temptations. However, our review also suggests that many findings that are interpreted as automatic self-regulation are inconclusive. It is not clear whether these findings involve goal pursuit, or whether the processes involved are truly automatic. Particularly the issue of uncontrollability – a hallmark of automaticity – has been underexamined in self-regulation research. Based on this review, we conclude that full automaticity in self-regulation cannot be assumed and discuss the possibility that it would even be dysfunctional.

He just wants to play: how goals determine the influence of violent computer games on aggression

Generally, the accessibility of goal-related constructs is inhibited upon goal fulfillment. In line with this notion, the current studies explored whether violent computer games may reduce relative accessibility of aggression if the game involves the fulfillment of an aggressive goal. Specifically, in Study 1, participants who watched a trailer for a violent computer game that fulfilled the goal of venting anger showed less relative accessibility of aggression compared to participants who watched the trailer without goal fulfillment. In Study 2, actually playing a violent computer game to vent anger also decreased the relative accessibility of aggression compared to a control condition in which the game was played without such a goal. Lastly, in Study 3, the relative accessibility of aggression was reduced after playing a violent computer game for participants who reported a high general tendency to vent their anger.

Neuraxial techniques in patients with pre-existing back impairment or prior spine interventions: a topical review with special reference to obstetrics

Many anaesthetists consider neurological disorders of all kinds as a contraindication for regional anaesthesia particularly for neuraxial techniques. This hesitation is partly rooted in fears of medicolegal problems but also in the heterogeneous literature. Therefore, the present topical review is an attempt to describe the feasibility and the risks of neuraxial techniques in patients with spinal injury, anatomical compromise, chronic back pain or previous spinal interventions, ranging from 'minor' types like epidural blood patches to major surgery such as Harrington fusions. Most reviews and case reports were describing experiences in obstetrics as these patients are more likely to insist on neuraxial blocks. In the acute phase of new neurologic injury, general anaesthesia may be the technique of choice to prevent further haemodynamic and respiratory deterioration. After the acute phase, current evidence is mostly reassuring with respect to the risks of neuraxial blocks as they may even be recommendable in some conditions. Ultrasound technology may be of additional help to increase the success rate. A careful pre-operative examination remains mandatory, while patients should be sufficiently informed about technical aspects and possible relapses or progression of their disease. When necessary, patients should have additional technical and clinical examinations as close as possible to surgery to establish the actual pre-operative status. Most patients may benefit more from spinal techniques rather than from less reliable epidural ones. High concentrations and volumes of local anaesthetics should be avoided at all times, especially in patients with nerve compression, large disc herniation or spinal stenosis.

RETRACTED: Sense Creative! The Impact of Global and Local Vision, Hearing, Touching, Tasting and Smelling on Creative and Analytic Thought

Förster, J., & Denzler, M. (2012). Sense Creative! The Impact of Global and Local Vision, Hearing, Touching, Tasting and Smelling on Creative and Analytic Thought. Social Psychological and Personality Science, 3(1), 108-117. (DOI: 10.1177/1948550611410890)

The editor of Social Psychological and Personality Science, along with the journal’s consortium of proprietor societies and its publisher, SAGE Publications, have retracted this article at the request of the Executive Board of the University of Amsterdam. The University has requested this retraction after conducting an inquiry into data irregularities contained in the article, and concluding that these irregularities represent a violation of academic integrity. The request from the University, signed by its Rector Magnificus, Prof D.C. van den Boom, states that "Scrutiny of the evidence by two committees on scientific integrity led to the conclusion that the data were manipulated: 'the diversity found in the scores of the control group is so improbably small that this cannot be explained by sloppy science or questionable research practices; intervention must have taken place in the presentation of the results of the 19 experiments described in the 2012 article. Based on this and based also on the inadequate explanation regarding the data set and the original data, a violation of academic integrity can be said to have taken place.' "

In response to the journal’s request for information regarding the authors’ roles, lead author Jens Förster stated that "My co-author of the paper, Markus Denzler, has nothing to do with the data collection or the data analysis."

Aggressive, funny, and thirsty: a Motivational Inference Model (MIMO) approach to behavioral rebound

Rebound of thoughts after thought suppression is widely documented. Much less is known about the effects of suppression on rebound of behavior. The current studies show that suppressing thoughts (Experiment 1 and 2) and suppressing behavior (Experiment 3) may cause rebound of behavior. In Experiment 1 suppressing thoughts of thirst rebounded in enhanced drinking, in Experiment 2 suppressing aggressive thoughts rebounded in subsequent aggression, and in Experiment 3 suppressing laughter rebounded in enhanced subsequent laughing. Supporting the Motivational Inference Model of postsuppressional rebound, the studies show that behavioral rebound is reduced if participants are led to believe that suppression is difficult for everybody (Experiments 1 and 2). Also consistent with this model is the finding that motivation to do the suppressed behavior mediated rebound (Experiment 3). The implications for rebound of unwanted behaviors are discussed.

Implicit affective cues and attentional tuning: an integrative review

A large and growing number of studies support the notion that arousing positive emotional states expand, and that arousing negative states constrict, the scope of attention on both the perceptual and conceptual levels. However, these studies have predominantly involved the manipulation or measurement of conscious emotional experiences (e.g., subjective feelings of happiness or anxiety). This raises the question: Do cues that are merely associated with benign versus threatening situations but do not elicit conscious feelings of positive or negative emotional arousal independently expand or contract attentional scope? Integrating theoretical advances in affective neuroscience, positive psychology, and social cognition, the authors propose that rudimentary intero- and exteroceptive stimuli may indeed become associated with the onset of arousing positive or negative emotional states and/or with appraisals that the environment is benign or threatening and thereby come to moderate the scope of attention in the absence of conscious emotional experience. Specifically, implicit "benign situation" cues are posited to broaden, and implicit "threatening situation" cues to narrow, the range of both perceptual and conceptual attentional selection. An extensive array of research findings involving a diverse set of such implicit affective cues (e.g., enactment of approach and avoidance behaviors, incidental exposure to colors signaling safety vs. danger) is marshaled in support of this proposition. Potential alternative explanations for and moderators of these attentional tuning effects, as well as their higher level neuropsychological underpinnings, are also discussed along with prospective extensions to a range of other situational cues and domains of social cognitive processing.

Hemispheric specialization and creative thinking: a meta-analytic review of lateralization of creativity

In the last two decades research on the neurophysiological processes of creativity has found contradicting results. Whereas most research suggests right hemisphere dominance in creative thinking, left-hemisphere dominance has also been reported. The present research is a meta-analytic review of the literature to establish how creative thinking relates to relative hemispheric dominance. The analysis was performed on the basis of a non-parametric vote-counting approach and effect-size calculations of Cramer's phi suggest relative dominance of the right hemisphere during creative thinking. Moderator analyses revealed no difference in predominant right-hemispheric activation for verbal vs. figural tasks, holistic vs. analytical tasks, and context-dependent vs. context-independent tasks. Suggestions for further investigations with the meta-analytic and neuroscience methodologies to answer the questions of left hemispheric activation and further moderation of the effects are discussed.

Going Beyond Information Given: How Approach Versus Avoidance Cues Influence Access to Higher Order Information

Three experiments examine the hypothesis that subtle cues of approach orientation facilitate access to higher order information, whereas subtle cues of avoidance orientation impede it. To test these predictions, in two studies, a backward-masking paradigm thought to measure access to higher order information at early perceptual stages was used, and arm positions of arm flexion versus arm extension were unobtrusively manipulated to induce interoceptive approach or avoidance situations. In a third study, using a procedural priming paradigm, exteroceptive cues associated with benign versus danger situations were manipulated and metaphor understanding served as a dependent variable. As predicted, although the diverse manipulations did not elicit different mood states, interoceptive and exteroceptive approach cues enhanced going beyond the information given, whereas avoidance cues impaired it. Implications are discussed.

Distancing from experienced self: how global-versus-local perception affects estimation of psychological distance

In 4 studies, the authors examined the prediction derived from construal level theory (CLT) that higher level of perceptual construal would enhance estimated egocentric psychological distance. The authors primed participants with global perception, local perception, or both (the control condition). Relative to the control condition, global processing made participants estimate larger psychological distances in time (Study 1), space (Study 2), social distance (Study 3), and hypotheticality (Study 4). Local processing had the opposite effect. Consistent with CLT, all studies show that the effect of global-versus-local processing did emerge when participants estimated egocentric distances, which are distances from the experienced self in the here and now, but did not emerge with temporal distances not from now (Study 1), spatial distances not from here (Study 2), social distances not from the self (Study 3), or hypothetical events that did not involve altering an experienced reality (Study 4).

Preparing for novel versus familiar events: shifts in global and local processing

Six experiments examined whether novelty versus familiarity influences global versus local processing styles. Novelty and familiarity were manipulated by either framing a task as new versus familiar or by asking participants to reflect upon novel versus familiar events prior to the task (i.e., procedural priming). In Experiments 1-3, global perception was enhanced after novelty priming or framing, whereas familiarity priming facilitated local perception relative to a control group. In Experiment 4, participants used more inclusive categories under novelty priming and narrower categories under familiarity priming. In Experiments 5-6, participants construed actions and products more abstractly when these were framed as novel as compared to familiar. These results support the construal level theory (N. Liberman & Y. Trope, 2008; Y. Trope & N. Liberman, 2003) contention that having less direct experience is associated with using higher construal levels. Implications of the findings for research on mood, processing styles, stereotypes, and consumer research are discussed.

Why Love Has Wings and Sex Has Not: How Reminders of Love and Sex Influence Creative and Analytic Thinking

This article examines cognitive links between romantic love and creativity and between sexual desire and analytic thought based on construal level theory. It suggests that when in love, people typically focus on a long-term perspective, which should enhance holistic thinking and thereby creative thought, whereas when experiencing sexual encounters, they focus on the present and on concrete details enhancing analytic thinking. Because people automatically activate these processing styles when in love or when they experience sex, subtle or even unconscious reminders of love versus sex should suffice to change processing modes. Two studies explicitly or subtly reminded participants of situations of love or sex and found support for this hypothesis.
