Effects of Spatial and Feature Attention on Disparity-Rendered Structure-From-Motion Stimuli in the Human Visual Cortex

An important advance in the study of visual attention has been the identification of a non-spatial component of attention that enhances the response to similar features or objects across the visual field. Here we test whether this non-spatial component can co-select individual features that are perceptually bound into a coherent object. We combined human psychophysics and functional magnetic resonance imaging (fMRI) to demonstrate the ability to co-select individual features from perceptually coherent objects. Our study used binocular disparity and visual motion to define disparity structure-from-motion (dSFM) stimuli. Although the spatial attention system induced strong modulations of the fMRI response in visual regions, the non-spatial system’s ability to co-select features of the dSFM stimulus was less pronounced and variable across subjects. Our results demonstrate that feature and global feature attention effects are variable across participants, suggesting that the feature attention system may be limited in its ability to automatically select features within the attended object. Careful comparison of the task design suggests that even minor differences in the perceptual task may be critical in revealing the presence of global feature attention.
The role of relational resources in the knowledge management capability and innovation of professional service firms 1

Adopting a relational perspective, this article investigates whether organizational relationship-building routines and relational coordination influence organizational knowledge management capability and ultimately innovation in professional service firms (PSFs). Using data collected from 120 accounting firms in Ireland, support is found for an inter-mediation model where both relational coordination and knowledge management capability intervene in the relationship between relational routines and innovation. Thus, a linkage model is supported whereby relational routines facilitate relational coordination, which enhances knowledge management capability, leading to innovation. This article provides evidence of the importance of relational routines and relational coordination in promoting a firm’s knowledge management capability and in fostering innovation. Results highlight the value of relational resources in PSFs and suggest a novel and easy-to-implement approach for knowledge and innovation management.
Three dimensional structure of the seventh transmembrane helical domain of the G-protein receptor, rhodopsin.

PURPOSE The three dimensional structure of a peptide comprising the sequence of the seventh transmembrane segment of the G-protein coupled receptor, rhodopsin, was determined in solution. METHODS The sequence of the seventh transmembrane segment of rhodopsin, which contains the NPxxY sequence that is highly conserved among G-protein coupled receptors and lys296 that forms the Schiff base with the retinal, was synthesized by solid phase peptide synthesis. The three dimensional structure was determined in solution by high-resolution nuclear magnetic resonance (NMR). RESULTS The structure revealed a helix-break-helix motif for this sequence. Two families of structures were observed which differed in the angle between the two helical segments. The sequence of this transmembrane segment overlapped significantly the sequence of a peptide from the carboxyl terminal of rhodopsin, the structure of which was solved previously. The redundant sequence formed a helix in both peptides. It was therefore possible to superimpose the redundant sequence of both peptides and construct a structure for rhodopsin encompassing residues 291-348. CONCLUSIONS This structure reveals locations of the lys296 and the acylation sites of rhodopsin that are consistent with the known biochemistry of this receptor. This segmentation approach to membrane protein structure provides important structural information in the absence of an X-ray crystal structure of rhodopsin. The approach is expected to be useful for other G-protein coupled receptors.
Culture and Subjective Well-Being

Adopting the dynamic constructivist approach, the present research tested the hypothesis that bicultural people’s subjective well-being (SWB) is more contingent on satisfaction with relationship-related domains and less contingent on satisfaction with self-related domains when Chinese cultural ideas are activated than when American ideas are activated. Two studies on Hong Kong undergraduates with different activation procedures (exposure to cultural icons in Study 1 and questionnaire language in Study 2) and different SWB measures (life satisfaction in Study 1 and subjective happiness in Study 2) provided convergent support to this hypothesis. The present research contributes to the existing understanding of culture and SWB by (a) examining the processes underlying the SWB judgment of bicultural individuals, (b) highlighting cross-situational variations of cultural influence on SWB judgment, and (c) allowing for testing causality of such influence.
Children’s Use of Communicative Intent in the Selection of Cooperative Partners

Within the animal kingdom, human cooperation represents an outlier. As such, there has been great interest across a number of fields in identifying the factors that support the complex and flexible variety of cooperation that is uniquely human. The ability to identify and preferentially interact with better social partners (partner choice) is proposed to be a major factor in maintaining costly cooperation between individuals. Here we show that the ability to engage in flexible and effective partner choice behavior can be traced back to early childhood. Specifically, across two studies, we demonstrate that by 3 years of age, children identify effective communication as “helpful” (Experiments 1 & 2), reward good communicators with information (Experiment 1), and selectively reciprocate communication with diverse cooperative acts (Experiment 2). Taken together, these results suggest that even in early childhood, humans take advantage of cooperative benefits, while mitigating free-rider risks, through appropriate partner choice behavior.
Efficient Collision Detection of Complex Deformable Models using AABB Trees

We present a scheme for exact collision detection between complex models undergoing rigid motion and deformation. The scheme relies on a hierarchical model representation using axis-aligned bounding boxes (AABBs). Recent work has shown that AABB trees are slower than oriented bounding box (OBB) trees for performing overlap tests. In this paper, we describe a way to speed up overlap tests between AABBs, such that for collision detection of rigid models, the difference in performance between the two representations is greatly reduced. Furthermore, we show how to update an AABB tree quickly as a model is deformed. We thus find AABB trees to be the method of choice for collision detection of complex models undergoing deformation. In fact, because they are not much slower to test, are faster to build, and use less storage than OBB trees, AABB trees might be a reasonable choice for rigid models as well.
The Man Behind the Woman

Little is known about the spousal support received by married executive women and the support behaviors that they value. This article details the results of a qualitative study of 20 senior and executive-level women, with the aim of understanding their received and valued spousal support. An inductive typology was developed through semistructured interviews of the supportive behaviors deemed general, most valued, and least valued, as well as those behaviors perceived as being unsupportive, across six categories: emotional support, help with household, help with family members, career support, esteem support, and husbands' career and lifestyle choices. This article concludes by contextualizing the results relative to existing research, discussing study implications and limitations, and presenting recommendations.
A LONGITUDINAL INVESTIGATION OF MANDARIN- SPEAKING PRESCHOOLERS' RELATION OF EVENTS IN NARRATIVES: FROM UNRELATED TO RELATED EVENTS

This study focuses on the way preschoolers relate events in a story. Twelve Mandarin-speaking preschoolers served as subjects; their narratives were elicited through the use of a picture book, Frog, where are you? Our data suggest that children's progression from treating single, unrelated events to related ones requires proper linguistic and cognitive capacities. The data also support earlier findings that most 5-year-olds are not able to relate a chain of events well. Additionally, it is found that there is dissociation in abilities for producing linguistic expressions and for inferring relations between events. We try to interpret the dissociation in terms of Karmiloff-Smith's problem-solving model.
Unconventional TV Detection using Mobile Devices

Recent studies show that the TV viewing experience is changing giving the rise of trends like "multi-screen viewing" and "connected viewers". These trends describe TV viewers that use mobile devices (e.g. tablets and smart phones) while watching TV. In this paper, we exploit the context information available from the ubiquitous mobile devices to detect the presence of TVs and track the media being viewed. Our approach leverages the array of sensors available in modern mobile devices, e.g. cameras and microphones, to detect the location of TV sets, their state (ON or OFF), and the channels they are currently tuned to. We present the feasibility of the proposed sensing technique using our implementation on Android phones with different realistic scenarios. Our results show that in a controlled environment a detection accuracy of 0.978 F-measure could be achieved.
Association between serum 25-hydroxyvitamin D levels and bone mineral density in normal postmenopausal women

Aim: This study was conducted with the objective of assessing serum 25-hydroxyvitamin D (25(OH)D) in postmenopausal women (PMW), to detect osteopenia or osteoporosis in PMW and to establish a correlation between serum 25(OH)D levels and bone mineral density (BMD). Materials and Methods: A total of 100 healthy PMW were selected, and a prospective observational study was conducted to correlate the BMD with serum 25(OH)D levels. Their laboratory investigations along with serum 25(OH)D levels were done. Their BMD was assessed with dual-energy X-ray absorptiometry at lumbar spine and neck of femur; T-scores were derived. Correlation analysis was done to investigate the relationship between serum 25(OH)D levels and BMD. Results: The proportion of osteoporosis at the hip was 31.9% in deficient group, 16.1% in insufficient, and 18.2% in sufficient group and at lumbar spine, it was 27.7%, 16.1%, and 22.7%, respectively. Forty-seven percent of PMW had deficient (<20 ng/ml) serum 25(OH)D levels and 31% had insufficiency. T-score at hip in deficient group was −2.05 ± 0.25, and in an insufficient group, it was −1.79 ± 0.13; T-score at lumbar spine was −1.92 ± 0.12 and −1.79 ± 0.12, respectively, but both were not statistically significant. Osteoporosis was seen in 24%, osteopenia in 55% at hip level and 23% and 59% respectively at lumbar spine. There was no association between serum 25(OH)D levels and BMD neither at hip nor at lumbar spine ( P = 0.51 and P = 0.79 respectively). Conclusion: In this study, among our cohort of patients there was no correlation between serum 25(OH)D levels and BMD. However, Vitamin D deficiency coexists with low BMD. Vitamin D insufficiency is a common risk factor for osteoporosis associated with increased bone remodeling and low bone mass.
Comparative Evaluation of the Effects of Fluoride Mouthrinse, Herbal Mouthrinse and Oil Pulling on the Caries Activity and Streptococcus mutans Count using Oratest and Dentocult SM Strip Mutans Kit

ABSTRACT Background: As the technological level of healthcare increases, it is important not to lose sight of the basics of patient care. No matter how sophisticated dental techniques have become, preventive dentistry still remains the foundation for oral health. Therefore, antimicrobial mouthrinses are developed to provide an effective means of preventing colonization by micro-organisms. Aim: The aim of this study was to evaluate and compare the antimicrobial activity of oil pulling, herbal mouthrinses and fluoride mouthwash on the caries activity and S. mutans counts in the saliva of children, using Oratest and Dentocult SM kit. Design: Fifty-two healthy children between the age group of 6 to 12 years were selected for the study and divided into four groups based on the mouthrinse used as group 1: fluoride, group 2: herbal, group 3: oil pulling and group 4: control. The estimation of caries activity and S. mutans was done prior to and after the subjects were instructed to use the mouthrinse twice daily for a period of 2 weeks. Statistical analysis: The comparisons were made by applying paired ‘t’ test with the level of significance set at p < 0.05. Difference between more than two mean values was done by using ANOVA and Post hoc Bonferroni test was used for multiple comparisons. Results and conclusion: The efficacy of fluoride and herbal mouthrinses was found to be comparable while oil pulling did not provide any additional benefit to be used as an effective antimicrobial agent in reducing the bacterial colonization of an individual.

Teasing and Its Long-Term Effects on Body Image

The main focus of the current research is to determine whether teasing by families has more of an influence on an individual’s body image than teasing by peers. Teasing is one of several factors that influence a person’s body image, and much research has focused on the significant long-term effects produced by teasing at an early age. This research explores exactly how teasing by family members and peers contributes to body dissatisfaction and negative body image. The research utilizes social comparison theory in order to determine how an individual’s body image is influenced by close family members and peers.
Regulation of CD20 in Rituximab-Resistant Cell Lines and B-cell Non-Hodgkin Lymphoma

Purpose: The aim of this research was to further investigate the contribution of CD20 antigen expression to rituximab activity and define the mechanisms responsible for CD20 downregulation in rituximab-resistant cell lines (RRCL). Experimental Design: Rituximab-sensitive cell lines, RRCL, and primary neoplastic B cells were evaluated by chromium-51 release assays, ImageStream image analysis, immunohistochemical staining, flow cytometric analysis, CD20 knockdown, promoter activity, chromatin immunoprecipitation (ChIP) analysis of CD20 promoter, and CD20 plasmid transfection experiments to identify mechanisms associated with CD20 regulation in RRCL. Results: RRCL exhibited a gradual loss of CD20 surface expression with repeated exposure to rituximab. We identified a CD20 antigen surface threshold level required for effective rituximab-associated complement-mediated cytotoxicity (CMC). However, a direct correlation between CD20 surface expression and rituximab-CMC was observed only in rituximab-sensitive cell lines. CD20 promoter activity was decreased in RRCL. Detailed analysis of various CD20 promoter fragments suggested a lack of positive regulatory factors in RRCL. ChIP analysis showed reduced binding of several key positive regulatory proteins on CD20 promoter in RRCL. Interleukin-4 (IL-4) induced higher CD20 promoter activity and CD20 expression but modestly improved rituximab activity in RRCL and in primary B-cell lymphoma cells. Forced CD20 expression restored cytoplasmic but not surface CD20, suggesting the existence of a defect in CD20 protein transport in RRCL. Conclusions: We identified several mechanisms that alter CD20 expression in RRCL and showed that, whereas CD20 expression is important for rituximab activity, additional factors likely contribute to rituximab sensitivity in B-cell lymphoma.

Pre-Service Teachers’ Teaching Anxiety about Mathematics and Their Learning Styles

The purpose of this study was to investigate the differences in the teaching anxiety of preservice teachers in mathematics according to their learning style preferences. There were a total of 506 pre-service teachers involved in this study. Of the total, 205 were pre-service elementary school teachers, 173 were pre-service elementary mathematics teachers, and 128 were pre-service secondary mathematics teachers. In the collection of the data, the researcher employed two types of instruments: the Learning Style Inventory (LSI) and the Mathematics Teaching Anxiety Scale (MATAS). The LSI determined the participants’ learning style preference: divergent, assimilator, convergent, and accommodator. The MATAS found the participants’ mathematics teaching anxiety level. The researcher used the one-way ANOVA with α = 0.05 in the analysis of the data. The study revealed that there were statistically significant differences in mathematics teaching anxiety between convergent and the other three types of learners: divergent, accommodator, and assimilator. The difference was in favour of convergent learners. In other words, convergent learners had less mathematics teaching anxiety than the other types of learners. The study also found that divergent learners showed the highest level of mathematics teaching anxiety.
Production of Milk and Nutrition of the Dependent Young of Free‐Ranging Koalas (Phascolarctos cinereus)

The production of milk by lactating females, and energy expenditure and foliage intake of their dependent young, were investigated in free‐ranging koalas. Koalas had the lowest mass‐specific daily milk‐energy production at peak lactation so far recorded in a mammal, but the duration of reproduction was 58% longer than the combined marsupial and eutherian average. As a consequence, the total energy input to reproduction in koalas was similar to that in other mammals. We propose that the prolonged lactation and low daily rate of energy transfer to the young by female koalas is an adaptation to the low energy availability from their diet of Eucalyptus foliage. Energy requirements (field metabolic rates) of young koalas were lower than those expected for typical marsupials (only 60% at permanent pouch exit), which may be a necessary preadaptation that allows the low rate of maternal energy transfer. However, the energy requirements of the adult females were no lower than expected for marsupials. This pattern of energy requirements and age resulted in a linear relationship between field metabolic rate and mass for the koalas in this population. Differences in milk production between the years of the study coincided with fluctuations in the availability of preferred young foliage, which suggests that lactational output by koalas may be flexible and affected by diet quality. Despite the interannual differences in milk production, growth of the young was similar in the two years.
Hemodynamic responses to graded lower body positive pressure.

Fourteen healthy young men were exposed to progressive increases in lower body positive pressure (LBPP) from 0 to 40 Torr in the supine position. Central venous pressure (CVP) increased 1.09 mmHg (P < 0.05) at 5 Torr LBPP. Between 20 and 40 Torr LBPP CVP increased 0.85 mmHg, resulting in a total increase of 2.06 mmHg (P < 0.05). During 0-20 Torr LBPP mean arterial pressure (MAP) increased from 86 to 89 mmHg with a slope of 0.15 mmHg/Torr LBPP. Stroke volume and cardiac output were significantly increased at 20 Torr LBPP. Beyond 20 Torr LBPP, MAP increased to 95 mmHg at 40 Torr (P < 0.05) with a slope of 0.32 mmHg/Torr LBPP. Forearm blood flow increased above rest at 40 Torr LBPP (P < 0.05). However, neither peripheral nor forearm vascular resistance decreased significantly from rest. Despite the significant increases in MAP, heart rate was unchanged above 20 Torr LBPP. These data suggest that LBPP produces increases in CVP at 0-20 Torr by translocation of blood volume from the legs to the thorax. At LBPP > 20 Torr, further increases in CVP and MAP were produced by other mechanisms possibly related to an activation of intramuscular pressure-sensitive receptors.
Validation of the Flush Method as an Alternative to Basal or Reflex Tear Collection

Purpose: To validate the more easily applicable “flush” tear collection technique as a viable alternative to basal and reflex tear collection. Materials and Methods: Total protein content (TPC) and immunoglobulin A (IgA) concentrations were determined in the basal, reflex, and flush tears of 16 healthy non-contact lens wearers. The overall protein profile was established using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and mass spectrometry (MS). Results: Collection-rates were 4.6 ± 6.7 μl/min, 13.9 ± 11.1 μl/min, and 25.7 ± 12.4 μl/min for the basal, reflex, and flush tears, respectively. TPC was 7.14 ± 2.22 mg/mL, 6.01 ± 2.11 mg/mL, and 3.79 ± 1.51mg/ mL for basal, reflex, and flush tears, respectively, with flush tears being significantly less concentrated than basal (p = 0.001) and reflex (p = 0.008). IgA concentration was 1.04 ± 0.29 mg/ mL, 0.64 ± 0.26 mg/mL, and 0.65 ± 0.23 mg/mL for basal, reflex, and flush tears, respectively, with basal tears being significantly more concentrated (p < 0.001). As a percentage of TPC, IgA represented 19.8 ± 14.9%, 11.4 ± 3.9%, and 19.8 ± 8.7% for basal, reflex, and flush, respectively. The flush was not significantly different to basal (p = 1.00) but significantly greater than reflex (p = 0.02). SDS-PAGE showed the same tear profiles for basal and flush tears. MS identified the most abundant proteins in all tear types. Conclusions: The flush method allows much faster collection than basal secretion sampling but returns essentially the same spectrum of proteins in similar proportions. This behavior is confirmation that the flush technique has utility as a more convenient alternative to basal tear sampling in studies involving composition analysis.
Young women's experiences of having Autism Spectrum Disorder

This thesis reports on a qualitative study applying Framework Analysis to narratives elicited from fourteen young women with high-functioning ASD. Semi-structured interviews highlighted experiences specific to being a young female with ASD, including delays in getting a diagnosis, vulnerability to abuse in relationships and compensatory strategies used in social situations. Challenges specific to females with ASD were singled out for discussion, as were clinical implications such as the need to increase medical and educational professionals’ knowledge of female ASD and suggestions for future quantitative research.
Desire, Settler Colonialism, and the Racialized Cowboy

In this paper, I argue that settler colonialism is a project of desire, and that attention to desire is particularly useful for understanding the relationship between racialized subjects, whose access to political power in settler regimes is tenuous and uneven. Drawing upon psychoanalytically-inflected theories of race, I examine how this desire is articulated, and look to its effects. To do so, I offer a reading of the 2004 South Asian-American film, Indian Cowboy, reflecting on how racialized subjects negotiate and express the desire to access and be included in settler subjectivity.
