Category Structure and Recognition Memory

Current models of human category learning and subsequent recognition are either exemplar-based, rule-based, or some combination of both approaches. We present learning and recognition data that cannot be accounted for by current approaches. The data suggest that the degree to which an item is remembered is determined by the strength of the expectation it violates. In our study, expectations take the form of simple, imperfect rules where the strength of the rules are determined by the number of items that follow the rules in training. Exemplarbased models cannot account for the results because they do not posit organizing knowledge structures that can be violated. The frequency insensitivity of rule-based accounts leads to their failure. We propose a cluster-based approach that is consistent with our findings, as well as findings from schema, stereotype, and basic memory research.
Fluently Processed Offers Must Have Greater Value: How Metacognitive Experience of Fluency Affects Deal Evaluations

In this article, we investigate how effects of credit card reward programs differ as a function of the partner brand of a cobranded credit card. Building on theories of processing fluency, we propose that the accessibility of the partner brand interacts with the categories of credit card rewards to affect evaluation of the credit card.When the accessibility of the partner brand is high, the congruency between the partner brand and categories of credit card rewards affects conceptual fluency of the rewards, which in turn has a positive influence on evaluation of the credit card. In contrast, when the accessibility of the partner brand is low, the congruency between the partner brand and credit card rewards does not have a significant influence on evaluation of the credit card because conceptual fluency of the rewards does not vary as a function of congruency. Further, we show that deal evaluation of credit card rewards mediates the effect of conceptual fluency on credit card evaluation. Finally, we discuss theoretical and managerial implications of this study.
El Niño and Greenhouse Warming: Results from Ensemble Simulations with the NCAR CCSM

Abstract The changes in model ENSO behavior due to an increase in greenhouse gases, according to the Intergovernmental Panel on Climate Change (IPCC) Business-As-Usual scenario, are investigated using a 62-member ensemble 140-yr simulation (1940–2080) with the National Center for Atmospheric Research Community Climate System Model (CCSM; version 1.4). Although the global mean surface temperature increases by about 1.2 K over the period 2000–80, there are no significant changes in the ENSO period, amplitude, and spatial patterns. To explain this behavior, an analysis of the simulation results is combined with results from intermediate complexity coupled ocean–atmosphere models. It is shown that this version of the CCSM is incapable of simulating a correct meridional extension of the equatorial wind stress response to equatorial SST anomalies. The wind response pattern is too narrow and its strength is insensitive to background SST. This leads to a more stable Pacific climate system, a shorter ENSO period, .
Secretory immunological response in infants and children to parainfluenza virus types 1 and 2

The secretory immunological responses to natural infection with parainfluenza viruses ae not well defined. Nasopharyngeal secretion specimens from 20 infants and children naturally infected with parainfluenza virus type 1 or type 2 were examined for class-specific antibody and virus-neutralizing activity. There was a marked discordance in individual secretions between immunoglobulin A (IgA) antibody (as measured by indirect immunofluorescence) and neutralizing activity (as determined by either hemadsorption plaque or 50% tissue culture infective dose reduction) to the infecting parainfluenza virus type. Many secretions contained neutralizing activity in the absence of detectable IgA antibody; conversely, secretions with measureable IgA antibody frequently lacked neutralizing activity. Moreover, there was no relationship between neutralizing activity and the course of illness. All 11 patients with serial secretion specimens showed a fourfold or greater titer rise in IgA antibody to the homologous parainfluenza virus type. Antibody usually appeared 7 to 10 days after the onset of symptoms and peaked at about 2 weeks. This response did not appear to be related to age or to severity of illness. in general, the secretory responses resembled those seen in infants infected with respiratory syncytial virus.
High expression of Sonic Hedgehog signaling pathway genes indicates a risk of recurrence of breast carcinoma

Background Abnormal activation of the Sonic Hedgehog (SHH) signaling pathway contributing to carcinogenesis of some organs has been reported in the literature. We hypothesize that activation of the SHH pathway contributes to the recurrence of breast carcinoma. Methods Fifty consecutive patients with invasive breast carcinoma following curative resection were enrolled in this prospective study. The ratios of messenger RNA (mRNA) expression for Sonic Hedgehog (SHH), patched homolog-1 (PTCH-1), glioma-associated oncogene-1 (GLI-1), and smoothened (SMOH) were measured between breast carcinoma tissue and paired noncancerous breast tissue. These ratios were compared with their clinicopathologic characteristics. These factors and the mRNA ratios were compared between patients with recurrence and those without recurrence. Results The size of the invasive cancer correlated significantly with the ratio of SHH mRNA (P=0.001), that of PTCH-1 mRNA (P=0.005), and that of SMOH mRNA (P=0.021). Lymph node involvement correlated significantly with the ratio of SMOH mRNA (P=0.041). The correlation between Her-2 neu and the ratio of GLI-1 mRNA was statistically significant (P=0.012). Each ratio of mRNA of SHH, PTCH-1, GLI-1, and SMOH correlated significantly with cancer recurrence (P<0.001 for each). Conclusion We suggest that high expression of SHH mRNA, PTCH-1 mRNA, GLI-1 mRNA, and SMOH mRNA in breast cancer tissue correlates with invasiveness and is a potential biomarker to predict postoperative recurrence.
Looking to the hands: Where we dwell in complex manual sequences

We investigated how processing unfolds across time as adults view novel manual activity. Adults advanced through slideshows of an actor performing sleight-of-hand manoeuvres; dwell times were recorded to each slide. As in past work involving larger-scale intentional action scenarios, adults allocated more attention to slides depicting breakpoints—transitions from one event segment to the next—than slides displaying mid-stream action, indicating that dwell times are sensitive to adults' recovery of segmental structure in intricate manual activity. Adults also allocated increased attention towards slides indicative of causal structure, indicating that dwell times index processing of causally relevant information as well as segmental structure. We were additionally curious if adults' learning outcomes would differ as a function of whether they paced themselves or watched slideshows advance at a computer-controlled pace. Memory did not differ, but adults viewing computer-controlled slideshows displayed an advantage in performing the tricks. A single attentional focus may have helped adults learn to re-enact the actions, relative to a split attentional focus.
Sudden Death in Familial Polymorphic Ventricular Tachycardia Associated With Calcium Release Channel (Ryanodine Receptor) Leak

Background— Familial polymorphic ventricular tachycardia (FPVT) is characterized by exercise-induced arrhythmias and sudden cardiac death due to missense mutations in the cardiac ryanodine receptor (RyR2), an intracellular Ca2+ release channel required for excitation-contraction coupling in the heart. Methods and Results— Three RyR2 missense mutations, P2328S, Q4201R, and V4653F, which occur in Finnish families, result in similar mortality rates of ≈33% by age 35 years and a threshold heart rate of 130 bpm, above which exercise induces ventricular arrhythmias. Exercise activates the sympathetic nervous system, increasing cardiac performance as part of the fight-or-flight stress response. We simulated the effects of exercise on mutant RyR2 channels using protein kinase A (PKA) phosphorylation. All 3 RyR2 mutations exhibited decreased binding of calstabin2 (FKBP12.6), a subunit that stabilizes the closed state of the channel. After PKA phosphorylation, FPVT-mutant RyR2 channels showed a significant gain-of-function defect consistent with leaky Ca2+ release channels and a significant rightward shift in the half-maximal inhibitory Mg2+ concentration (IC50). Treatment with the experimental drug JTV519 enhanced binding of calstabin2 to RyR2 and normalized channel function. Conclusions— Sympathetic activation during exercise induces ventricular arrhythmias above a threshold heart rate in RyR2 mutation carriers. Simulating the downstream effects of the sympathetic activation by PKA phosphorylation of RyR2 channels containing these FPVT missense mutations produced a consistent gain-of-function defect. RyR2 function and calstabin2 depletion were rescued by JTV519, suggesting stabilization of the RyR2 channel complex may represent a molecular target for the treatment and prevention of exercise-induced arrhythmias and sudden death in these patients.
Persistence Hunting by Modern Hunter- Gatherers

Endurance running may be a derived capability of the genus Homo and may have been instrumental in the evolution of the human body form. Two hypotheses have been presented to explain why early Homo would have needed to run long distances: scavenging and persistence hunting. Persistence hunting takes place during the hottest time of the day and involves chasing an animal until it is run to exhaustion. A critical factor is the fact that humans can keep their bodies cool by sweating while running. Another critical factor is the ability to track down an animal. Endurance running may have had adaptive value not only in scavenging but also in persistence hunting. Before the domestication of dogs, persistence hunting may have been one of the most efficient forms of hunting and may therefore have been crucial in the evolution of humans.
Induction of resistance against the transplantation of leukemias induced by Rauscher virus.

Summary A state of relative resistance against the transplantation of isografts of leukemias induced by the Rauscher virus (RV) was developed in BALB/c and CDF 1 mice by pretreatment with X-irradiated tumor cells. In mice pretreated with cells from 1 tumor, significant cross-protection was obtained for all other RV-induced tumors tested and for some tumors induced by Moloney virus, but not for leukemia L1210. Although marginal resistance was observed on a few occasions, the inoculation of infectious RV was not an efficient method of inducing transplantation resistance in BALB/c and CDF 1 mice. In CDF 1 mice resistance to grafts of RV-induced tumors was accompanied by resistance to challenge with RV and the presence of circulating RV neutralizing antibodies.
Automaton-based Non-interference Monitoring

This report presents a non-interference monitoring mechanism for sequential programs. Non-interference is a property of the information flows of a program. It implies the respect of the confidentiality of the secret information manipulated. The approach taken uses an automaton based monitor. During the execution, abstractions of the events occurring are sent to the automaton. The automaton uses those inputs to track the information flows and to control the execution by forbidding or editing dangerous actions. The mechanism proposed is proved to be sound and more efficient than a type system similar to the historical one developed by Volpano, Smith and Irvine.
Focal lesion at the midline of the prostate on transrectal ultrasonography: take it or leave it?

Purpose The purpose of this study was to analyze the detection rate of prostate cancers from targeted biopsy specimens of midline focal lesions and to investigate the ultrasonographic findings to reduce unnecessary additional targeted biopsies. Methods Ninety-eight men with midline focal lesions detected on transrectal ultrasonography were enrolled. Additional targeted biopsies for midline focal lesions were performed after 12-core random systematic biopsies. Correlations between the ultrasonographic characteristics of midline focal lesions and the pathologic results were analyzed. Results Twenty of 98 targeted biopsy cores (20.4%) were positive for malignancy. In a univariate analysis, midline focal lesions without bulging contours (P=0.023), with involved margins (P=0.001), without hypoechoic perilesional rims (P=0.005), and with longer diameters (P=0.005) were statistically significant for cancer detection. In a multivariate analysis, involved margin (P=0.027), having longer diameter (P=0.011) or absence of hypoechoic perilesional rim (P=0.025) made a statistically significant contribution to cancer detection. Conclusion Biopsy of midline focal lesions was not always non-significant in the detection of prostate cancer. Additional targeted biopsies should be considered in cases of midline focal lesions with involved margins but without hypoechoic perilesional rims.
Multi‐Index Attribution of Extreme Winter Air Quality in Beijing, China

High‐impact poor air quality events, such as Beijing's so‐called “Airpocalypse” in January 2013, demonstrate that short‐lived poor air quality events can have significant effects on health and economic vitality. Poor air quality events result from the combination of the emission of pollutants and meteorological conditions favorable to their accumulation, which include limited scavenging, dispersion, and ventilation. The unprecedented nature of events such as the 2013 Airpocalypse, in conjunction with our nonstationary climate, motivate an assessment of whether climate change has altered the meteorological conditions conducive to poor winter air quality in Beijing. Using three indices designed to quantify the meteorological conditions that support poor air quality and drawing on the attribution methods of Diffenbaugh et al. (2017, https://doi.org/10.1073/pnas.1618082114), we assess (i) the contribution of observed trends to the magnitude of events, (ii) the contribution of observed trends to the probability of events, (iii) the return interval of events in the observational record, preindustrial model‐simulated climate and historical model‐simulated climate, (iv) the probability of the observed trend in the preindustrial and historical model‐simulated climates, and (v) the relative influences of anthropogenic forcing and natural variability on the observed trend. We find that anthropogenic influence has had a small effect on the probability of the January 2013 event in all three indices but has increased the probability of a long‐term positive trend in two out of three indices. This work provides a framework for both further understanding the role of climate change in air quality and expanding the scope of event attribution.
Women and Competition in Elimination Tournaments

This article examines how professional female tennis players react to (a) prize incentives and (b) heterogeneity in ex ante players' abilities. It is found that a larger prize spread encourages women to increase effort, even when controlling for many tournament and player characteristics. Further results indicate that uneven contests lead favorites to win more games and underdogs to be less performing. They also show that the performance differential among players increases with the ranking differential. These findings suggest that the outcome of a match is more linked to players' abilities than to players' incentives to adjust effort according to success chances.
Design diversity redundancy with spatial-temporal voting applied to data acquisition systems

Due to the technology scaling of modern integrated circuits, the electronic systems are increasingly become more susceptible to transient faults, potentially caused by radiation interaction with the semiconductor. Furthermore the variability of production process, associated to this scaling, and the increase on the operating frequencies, lead to an increase on the probability of faults of complex circuits. This work addresses the concepts of redundancy and diversity with the DTMR technique to improve the fault tolerance of a data acquisition system. A physical implementation is made using a Programmable SoC from Cypress Semiconductor. Results indicate that the system is effective to tolerate single, double and multiple bit-flip faults.
The volume fraction of a non–overlapping germ–grain model

We discuss the volume fraction of a model of non--overlapping convex grains. It is obtained from thinning a Poisson process where each point has a weight and is the centre of a grain, by removing any grain that is overlapped by one of larger or equal weight. In the limit as the intensity of the Poisson process tends to infinity, the model can be identified with the intact grains in the dead leaves model if the weights are independent of the grain sizes. In this case we can show that the volume fraction is at most $1/2^d$ for $d=1$ or $2$ if the shape is fixed, but the size and the orientation are random. The upper bound is achieved for centrally symmetric sets of the same size and orientation. For general $d$ we can show the upper bound, $1/2^d$, for spherical grains with two--point radius distribution. If dependence between weight and size is allowed, it is possible to achieve a volume fraction arbitrarily close to one.
Varieties of functional deficits in prosopagnosia.

Prosopagnosia is a neurologically based deficit characterized by the inability to recognize faces of known individuals in the absence of severe intellectual, perceptual, and memory impairments. The nature of the underlying disturbance was investigated in three patients in an attempt to identify the structural and functional levels at which the processing of faces breaks down, the relation between prosopagnosia and associated deficits, and the specificity of the prosopagnosic disturbance. The breakdown of face processing resulted from unilateral damage in different cerebral structures of the right hemisphere in the three patients, and it involved different functional levels of face processing, but all three patients displayed perceptual impairments of unequal severity. In one patient (R.M.), the deficit encompassed all perceptual operations on faces, including matching identical views of the same faces, but it did not extend to all categories of objects characterized by a close similarity among their instances; the second patient (P.M.) exhibited a less severe perceptual impairment but was unable to derive the configurational properties from a facial representation and to extract its physiognomic invariants; the third patient (P.C.) had not lost the capacity to differentiate faces on the basis of their configurations but could not associate a facial representation with its pertinent memories. Associated deficits were present in each patient but differed depending on the anatomofunctional locus of the breakdown, although all patients were impaired at recognizing noncanonical views of objects that they readily recognized when shown from a conventional viewpoint. However, performance dissociation within patients and double dissociation between patients suggest that these associated deficits are not necessary concomitants of prosopagnosia.
GRADE AND GENDER DIFFERENCES IN ELEMENTARY AND SECONDARY STUDENTS' MOTIVATIONAL REGULATIONS FOR PARTICIPATING IN SCHOOL PHYSICAL EDUCATION*

The purpose of the study was to examine grade and gender differences in students' motivational regulations for participating in school physical education. Participants were 1402 students, 681 boys and 704 girls (17 students were excluded as they did nοt provide grade or gender), of 5 th (n=358), 7 th (n=348), 9 th (n=346) and 11 th grade (n=333), who participated in 72 regular physical education classes from 33 schools of 11 cities in central and north Greece. The mo- tivational regulation questionnaire (Goudas, Dermitzaki & Bagiatis, 2000) with the addition of the amotivation subscale (Goudas, 1994) was used for the evaluation of students' motivational regulations. Four (grade) x 2 (gender) ANOVAs and post hoc comparisons revealed significant reduction in intrinsic motivation and identified regulation from 5 th to 7 th , from 7 th to 9 th and from 9 th to 11 th grade, while boys, independently of grade, referred higher levels of intrinsic motivation and identified regulation compared with girls. Moreover, boys compared with girls referred higher levels of external regulation and amotivation in 5 th grade, while girls referred higher levels of amotivation in 11 th grade. These results are discussed with reference to the as- sumptions of self-determination theory (Deci & Ryan, 2004), emphasizing in practical implication for physical education.
Depth CNNs for RGB-D Scene Recognition: Learning from Scratch Better than Transferring from RGB-CNNs

Scene recognition with RGB images has been extensively studied and has reached very remarkable recognition levels, thanks to convolutional neural networks (CNN) and large scene datasets. In contrast, current RGB-D scene data is much more limited, so often leverages RGB large datasets, by transferring pretrained RGB CNN models and fine-tuning with the target RGB-D dataset. However, we show that this approach has the limitation of hardly reaching bottom layers, which is key to learn modality-specific features. In contrast, we focus on the bottom layers, and propose an alternative strategy to learn depth features combining local weakly supervised training from patches followed by global fine tuning with images. This strategy is capable of learning very discriminative depth-specific features with limited depth images, without resorting to Places-CNN. In addition we propose a modified CNN architecture to further match the complexity of the model and the amount of data available. For RGB-D scene recognition, depth and RGB features are combined by projecting them in a common space and further leaning a multilayer classifier, which is jointly optimized in an end-to-end network. Our framework achieves state-of-the-art accuracy on NYU2 and SUN RGB-D in both depth only and combined RGB-D data.
Effects of Word-of-Mouth versus Traditional Marketing: Findings from an Internet Social Networking Site

The authors study the effect of word-of-mouth (WOM) marketing on member growth at an Internet social networking site and compare it with traditional marketing vehicles. Because social network sites record the electronic invitations from existing members, outbound WOM can be precisely tracked. Along with traditional marketing, WOM can then be linked to the number of new members subsequently joining the site (sign-ups). Because of the endogeneity among WOM, new sign-ups, and traditional marketing activity, the authors employ a vector autoregressive (VAR) modeling approach. Estimates from the VAR model show that WOM referrals have substantially longer carryover effects than traditional marketing actions and produce substantially higher response elasticities. Based on revenue from advertising impressions served to a new member, the monetary value of a WOM referral can be calculated; this yields an upper-bound estimate for the financial incentives the firm might offer to stimulate WOM.
