BAIAP2 Is Related to Emotional Modulation of Human Memory Strength

Memory performance is the result of many distinct mental processes, such as memory encoding, forgetting, and modulation of memory strength by emotional arousal. These processes, which are subserved by partly distinct molecular profiles, are not always amenable to direct observation. Therefore, computational models can be used to make inferences about specific mental processes and to study their genetic underpinnings. Here we combined a computational model-based analysis of memory-related processes with high density genetic information derived from a genome-wide study in healthy young adults. After identifying the best-fitting model for a verbal memory task and estimating the best-fitting individual cognitive parameters, we found a common variant in the gene encoding the brain-specific angiogenesis inhibitor 1-associated protein 2 (BAIAP2) that was related to the model parameter reflecting modulation of verbal memory strength by negative valence. We also observed an association between the same genetic variant and a similar emotional modulation phenotype in a different population performing a picture memory task. Furthermore, using functional neuroimaging we found robust genotype-dependent differences in activity of the parahippocampal cortex that were specifically related to successful memory encoding of negative versus neutral information. Finally, we analyzed cortical gene expression data of 193 deceased subjects and detected significant BAIAP2 genotype-dependent differences in BAIAP2 mRNA levels. Our findings suggest that model-based dissociation of specific cognitive parameters can improve the understanding of genetic underpinnings of human learning and memory.
Allodynia after lateral-medullary (Wallenberg) infarct. A PET study.

We used PET to study regional cerebral blood flow (rCBF) changes in nine patients with unilateral central pain after a lateral medullary infarct (Wallenberg's syndrome). All patients presented, on the abnormal side, a combination of hypaesthesia to noxious and thermal stimuli and allodynia to rubbing of the skin with a cold object (i.e. abnormal pain to innocuous stimulation). The rCBF responses during allodynia were compared with those obtained during stimulation of the normal side using (i) a cold non-noxious stimulus identical to that applied to the painful side, and (ii) an electrical high-frequency stimulus at painful ranges. Statistical analysis disclosed two abnormal patterns of rCBF change during allodynia. First, there is a quantitative change whereby the blood flow response was out of proportion with the actual intensity of the stimulus, i.e. the pattern of activation by innocuous rubbing of the skin was in our patients identical to that previously reported in response to painful stimuli in normal subjects. This pattern concerned primarily the contralateral thalamus in its lateral half and the primary and somatosensory areas, as well as inferior parietal [Brodmann area (BA) 39/40], anterior insular (BA 6) and medial prefrontal (BA 10) cortices. Thalamic over-activity may reflect abnormal transduction and amplification of sensory inputs after spinothalamic deafferentation. This might be responsible for both increased rCBF in multiple cortical targets and the perceived shift of stimulus intensity from innocuous to painful ranges. The second abnormality associated with allodynic sensation was qualitative. It concerned exclusively the contralateral cingulate gyrus, which did not exhibit the usual pain-related rCBF increase reported in normal subjects. This abnormal cingulate response may account for the peculiar response of lateral medullary infarct patients to allodynic pain, which is not simply perceived as an exaggerated pain sensation, but as a new, strange and extremely unpleasant feeling, not previously experienced by the patients.
Relation between resiliency and post-traumatic growth in a group of paramedics: The mediating role of coping strategies.

OBJECTIVES The purpose of the research is to investigate the mediating role of coping strategies for stress in the relation between resiliency and post-traumatic growth in a group of paramedics. MATERIAL AND METHODS Data of 80 paramedics who have experienced traumatic event at their worksites was analyzed. The age range of the participants was 21-67 years old (mean: 35.47, standard deviation: 10.21). The Post-traumatic Growth Inventory, the Assessment Resiliency Scale and Inventory to Measure Coping Strategies for Stress--Mini-Cope were used in the study. RESULTS Venting of negative emotions and denial appeared as suppressors in analyzing the relation, while planning plays mediating role between resiliency and post-traumatic growth. CONCLUSIONS In the process of post-traumatic growth, both avoidance and problem-focused strategies are important. Moreover, controlling such strategies as Venting and Denial may result in a high level of posttraumatic growth in the study group. The data supports that resiliency may have direct or indirect impact on post-traumatic changes. The results allow to understand the mechanisms of resiliency better, that relationship with post-traumatic growth is ambiguous.
The Effect of Banner Advertising on Internet Purchasing

This article focuses on whether banner advertising affects purchasing patterns on the Internet. Using a behavioral database that consists of customer purchases at a Web site along with individual advertising exposure, the authors measure the impact of banner advertising on current customers' probabilities of repurchase, while accounting for duration dependence. The authors model the probability of a current customer making a purchase in any given week (since the last purchase) with a survival model that uses a flexible, piecewise exponential hazard function. The advertising covariates are purely advertising variables and advertising/individual browsing variables. The model is cast in a hierarchical Bayesian framework, which enables the authors to obtain individual advertising response parameters. The results show that the number of exposures, number of Web sites, and number of pages all have a positive effect on repeat purchase probabilities, whereas the number of unique creatives has a negative effect. Returns from targeting are the highest for the number of advertising exposures. The findings also add to the general advertising literature by showing that advertising affects the purchase behavior of current (versus new) customers.
Signal Propagation on Three Phases Power Distribution Lines as Communications Channels for Intelligent Systems

Powerline can be used as a propagation channel to transfer the information of some communication systems. In order to employ all three-phase powerlines, a novel communication channel model is proposed in this paper. One of the advantages of the proposed model is that both source inner admittance and load admittance matrices are considered and this can use the proposed model to simulate a practical powerline network. Based on the multiconductor transmission lines theory, a complete solution of the voltages and currents on all three-phase powerlines is derived in detailed. The communication signal strength of power-line networks can be predicted. The comparison between theoretical results and measurements is obtained and a good agreement between the analytical model results and measurements is presented, which means the proposed channel model and the derived formula are correct
Unwanted pursuit behavior after breakup

Former partners comprise the most important subgroup of stalkers. However, contextual factors related to the breakup are hardly examined to explain ex-partner pursuit. In a community sample of 184 separated persons, about one fifth perpetrated at least one unwanted pursuit behavior (UPB) in the past two weeks. Being woman, having a lower than Bachelor’s education level, and showing less social desirable response tendencies raised the observed number of perpetrated UPBs. Beyond these effects, the number of enacted UPBs increased when one more strongly attributed the cause of the breakup to the ex-partner or external factors, and when one appraised the ex-partner as the breakup initiator. Breakup reasons, namely the ex-partner’s lack in meeting family obligations and own infidelity, also related to more perpetrations of UPB albeit inferior to subjective appraisals with regard to the cause and the initiation of the separation. Finally, participants who felt more lonely negative after breaking up showed more UPBs. The results enlighten that the examination of breakup characteristics gains further attention and imply that clinical treatment might benefit from fostering cognitive reconstructions and breakup adjustment.

Helbing / Schweitzer / Keltsch / Molnár : Active Walker Model for Trail Formation 2

Active walker models have recently proved their great value for describing the formation of clusters, periodic patterns, and spiral waves as well as the development of rivers, dielectric breakdown patterns, and many other structures. It is shown that they also allow to simulate the formation of trail systems by pedestrians and ants, yielding a better understanding of human and animal behavior. A comparison with empirical material shows a good agreement between model and reality. Our trail formation model includes an equation of motion, an equation for environmental changes, and an orientation relation. It contains some model functions, which are specified according to the characteristics of the considered animals or pedestrians. Not only the kind of environmental changes differs:
Responding to bereavement, grief and loss: Charting the troubled relationship between research and practice in youth offending services

Abstract This paper is concerned with the professional response to bereavement, grief, and loss experienced by children and young people subject to criminal justice interventions. It looks at the most common responses within the youth offending service and secure estate to this ‘need’ and asks what this says about the nexus between theory, research, and practice. Here the authors draw on both criminological research and the literature around death and dying to discuss what is appropriate, what is ethical, and ‘what works’ (if anything) in such interventions. They argue that interpretations of the Risk Factor Prevention Paradigm (RFPP), the currently dominant ‘mode of understanding’ in youth justice, and risk management can result in the relative neglect of bereavement and loss as ‘welfare issues’ beyond the remit of those engaged in offender rehabilitation. The paradigm's focus on individual pathology also tends to militate against youth practitioner involvement in more social and community-orientated responses to bereavement and loss, despite growing evidence from around the world of the efficacy of such restorative approaches. The authors conclude by reflecting on the call to ‘bridge the gap’ (Bridging Work Group, 2005) between research and practice in bereavement, asking how a similar process might be facilitated within youth justice.
The Labour of Aesthetics and the Aesthetics of Organization

This article develops the conceptualization and analysis of aesthetic labour in two parts. The first part focuses on conceptualizing aesthetic labour. We critically revisit the emotional labour literature, arguing that the analysis of interactive service work is impeded by the way in which its corporeal aspects are retired and that, by shifting the focus from emotional to aesthetic labour, we are able to recuperate the embodied character of service work. We then explore the insights provided by the sociological perspectives on the body contained in the works of Goffman and Bourdieu in order to conceptualize aesthetic labour as embodied labour. In the second part, we develop our analysis of aesthetic labour within the context of a discussion of the aesthetics of organization. We discern three ways in which aesthetics is recognized to imbue organization: aesthetics of organization, aesthetics in organization and aesthetics as organization. We contend that employees are increasingly seen not simply as `software' but as `hardware', in the sense that they too can be corporately moulded to portray the organizational aesthetic. We ground this analysis in a case study from research conducted by the authors.
MEASUREMENT OF FAMILY COMMUNICATION PATTERNS

Analysis of a three-wave panel study of parent-child pairs examined indicator reliability, longitudinal stability, and parent-child similarity of family communication patterns. Estimates of reliability and intergenerational similarity were obtained using a multiple indicator model (LISREL) that treats individual measures as indicators of an underlying latent construct. Analyses were performed for single items measured at three time points and for multiple items at single time points, both revealing considerable measurement error. With unreliability taken into account, there was substantial dissimilarity in the perceptions of parents and children within the same family. A reconceptualization of research on family communication patterns focusing on the antecedents of family norms and the dynamic character of family interaction was discussed.
The Impact of Prosocial Television News on Children’s Prosocial Behavior: An Experimental Study in the Netherlands

The aim of this experimental study was to examine whether prosocial behavior in television news affects children’s prosocial intentions and behaviors. In this study, 372 Dutch children (9–13 years old) participated. Children in the experimental condition were exposed to prosocial news showing children organizing a fundraising action for UNICEF. In the control condition, children were exposed to news about UNICEF in which no prosocial behavior was included. Afterwards, children were given the opportunity to donate to UNICEF, which served as an index of prosocial behavior. Prosocial intentions were captured using paper-and-pencil questionnaires. Regression analysis demonstrated that, while controlling for important confounders, children exposed to prosocial news were significantly more willing to help with setting up a project for UNICEF and donated more to UNICEF compared to children who did not watch prosocial news. These findings highlight that prosocial television can function as a tool for positive social change among children.
Arterial Stiffness and Cardiovascular Therapy

The world population is aging and the number of old people is continuously increasing. Arterial structure and function change with age, progressively leading to arterial stiffening. Arterial stiffness is best characterized by measurement of pulse wave velocity (PWV), which is its surrogate marker. It has been shown that PWV could improve cardiovascular event prediction in models that included standard risk factors. Consequently, it might therefore enable better identification of populations at high-risk of cardiovascular morbidity and mortality. The present review is focused on a survey of different pharmacological therapeutic options for decreasing arterial stiffness. The influence of several groups of drugs is described: antihypertensive drugs (angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, calcium channel blockers, beta-blockers, diuretics, and nitrates), statins, peroral antidiabetics, advanced glycation end-products (AGE) cross-link breakers, anti-inflammatory drugs, endothelin-A receptor antagonists, and vasopeptidase inhibitors. All of these have shown some effect in decreasing arterial stiffness. Nevertheless, further studies are needed which should address the influence of arterial stiffness diminishment on major adverse cardiovascular and cerebrovascular events (MACCE).
Laparoscopic versus open cholecystectomy: Hospitalization, sick leave, analgesia and trauma responses

Laparoscopic cholecystectomy has rapidly become established as the treatment of choice for cholecystolithiasis. There is very little evidence, however, to support the claimed benefit to patients. In the present study 30 consecutive patients below the age of 65 years without acute cholecystitis and with no signs of common bile duct stones were randomized to laparoscopic or conventional open eholecystectomy. Median (interquartile range) intravenous consumption of pethidine with a patientcontrolled injection device between 13 and 24 h after surgery was 125 (62–175) mg in patients who underwent the laparoscopic procedure and 200 (150–250) mg in those who had open operation. Urinary adrenaline and cortisol levels as well as those of plasma glucose, C‐reactive protein and interleukin 6 were increased after surgery in both groups of patients, but without any significant difference between them. The mean(s.d.) duration of postoperative hospital stay (2·8(0·8) versus 1·8(0·6) days) and sick leave (24·0(4·4) versus 11·7(4·1) days) was significantly longer with open than laparoscopic cholecystectomy. The findings demonstrate obvious advantages of laparoscopic surgery as regards postoperative pain and convalescence, although factors reflecting the magnitude of trauma did not differ.
A comparison of reflectance properties on polymer micro-structured functional surface

The directionality of the geometry makes the contrast 0 ° - 90 ° stronger than the 90 ° - 180 ° . Abstract In this study, a functional micro-structure surface [1] has been developed as a combination of arrays of micro ridges. The scope of the surface is to achieve specific directional optical properties: that is, under constrained lighting, from the corresponding horizontally orthogonal The sample is composed of 12 different anisotropic surfaces, and angle respect The silicone replica technology and by hot embossing Acrylonitrile gonioreflectometer to determine the directional surface reflectance of each surface to varying light and camera positions. The presented results show that the replication processes and the polymeric material have a strong impact on the contrast under constrained lightening. More specifically, the reflectance properties are strongly influenced by the geometry of the structure and by the colour.
Understanding dynamic capabilities

Defining ordinary or ‘zero-level’ capabilities as those that permit a firm to ‘make a living’ in the short term, one can define dynamic capabilities as those that operate to extend, modify or create ordinary capabilities. Logically, one can then proceed to elaborate a hierarchy of higher-order capabilities. However, it is argued here that the strategic substance of capabilities involves patterning of activity, and that costly investments are typically required to create and sustain such patterning—for example, in product development. Firms can accomplish change without reliance on dynamic capability, by means here termed ‘ad hoc problem solving. ’ Whether higher-order capabilities are created or not depends on the costs and benefits of the investments relative to ad hoc problem solving, and so does the ‘level of the game’ at which strategic competition effectively occurs.

Vasoactive factors in sickle cell disease: In vitro evidence for endothelin‐1‐mediated vasoconstriction

While systemic plasma endothelin‐1 (ET‐1) levels are increased during acute crisis in sickle cell disease, the relative levels of potent vasoactive factors that contribute to the regulation of vascular function, such as ET‐1, NO, and cell‐free hemoglobin, during the course of periodic vaso‐occlusive episodes remain unclear. Moreover, whether and to what extent sickling‐induced release of ET‐1 alters vascular tone is not completely understood. To investigate the sequential changes in circulating vasoactive factors, we measured plasma ET‐1, NO metabolites (NOx), and cell‐free hemoglobin (Hb) before (steady‐state), during (crisis), and after a vaso‐occlusive (post‐crisis) episode. Steady‐state ET‐1 levels (fmol/mL) increased from 2.3 ± 0.4 to 11.0 ± 1.4 and 4.2 ± 1.0 during crisis and post‐crisis periods, respectively. There was no significant difference in plasma NOx levels. Cell‐free Hb levels were significantly higher in sickle cell patients in all phases as compared to the control group, and especially during crisis cell‐free Hb levels were elevated by 4‐fold (209,000 ± 31,000 vs. 46,000 ± 5,300 ng/mL in steady‐state). Conditioned medium from human pulmonary artery endothelial cells exposed to sickled erythrocytes prepared by deoxygenation induced contraction of aortic rings, and this effect was blocked by an ETA receptor antagonist. These findings indicate that ET‐1 is the predominant contractile factor released by cultured endothelial cells upon exposure to deoxygenated sickled SS erythrocytes and ET‐1–NO–NO scavenger balance is altered in favor of vasoconstriction during an acute episode in SCD.

R‐vine models for spatial time series with an application to daily mean temperature

We introduce an extension of R‐vine copula models to allow for spatial dependencies and model based prediction at unobserved locations. The proposed spatial R‐vine model combines the flexibility of vine copulas with the classical geostatistical idea of modeling spatial dependencies using the distances between the variable locations. In particular, the model is able to capture non‐Gaussian spatial dependencies. To develop and illustrate our approach, we consider daily mean temperature data observed at 54 monitoring stations in Germany. We identify relationships between the vine copula parameters and the station distances and exploit these in order to reduce the huge number of parameters needed to parametrize a 54‐dimensional R‐vine model fitted to the data. The new distance based model parametrization results in a distinct reduction in the number of parameters and makes parameter estimation and prediction at unobserved locations feasible. The prediction capabilities are validated using adequate scoring techniques, showing a better performance of the spatial R‐vine copula model compared to a Gaussian spatial model.
Person re-identification based on deep spatio-temporal features and transfer learning

Person re-identification has become a hot research topic due to its importance in surveillance and forensics applications. The purpose of person re-identification is to find the same person from disjoint camera views at different time. Most of the existing methods try to identify the person by measuring the similarity of two still images from different camera views, which only uses intraimage features such as color, shape and texture. In this paper, we propose a person re-identification architecture which analyzes a sequence pair while not an image pair, so not only intra-image features but also the gait feature is also considered. In contrast to existing works that use handcrafted features, our method automatically learns spatio-temporal features optimal for the person re-identification task with a deep convolutional network. To learn a discriminant metric, we use a subspace and metric learning method called Cross-view Quadratic Discriminant Analysis (XQDA). The process of XQDA is also called transfer learning. Experiments show that our method significantly outperforms the state of the art on both a large dataset (CUHK03) and a medium-sized dataset (CUHK01). We also get a better performance on a small dataset (VIPeR) with a pre-trained network without fine-tuning.
