The Ecological Validity of Photographic Slides and Videotapes in Simulating the Service Setting

In the study of consumers' evaluation of the service setting, laboratory experiments using environmental simulations provide researchers with a level of control that can otherwise be difficult to achieve in field studies. This article demonstrates that photographic slides and videotapes, used as environmental simulations in testing a theory of crowding, have ecological validity. The same theoretical model is tested with data obtained from a field quasi-experimental study and with data from a laboratory study that used photographic slides and videotapes to simulate the service setting. Conditions that may constrain the applications of various kinds of environmental simulations in consumer research on services are also discussed. Copyright 1992 by the University of Chicago.
The power of caring and generativity in building strategic adaptability

In this study, we integrate relational theory and the upper echelon perspective to explore how and why caring and generative relationships in top management teams (TMTs) can be a source for building strategic adaptability. We argue that when TMT members care for each other's inner needs, a generative psychological space (which allows members to experience positivity and produce enduring transformative outcomes) is nurtured. This generative psychological space, in turn, helps to build a capacity to respond proactively to the external environment and adapt well to environmental jolts. The results lend support to our hypothesized model in which caring among TMT members nurtures generativity, which in turn enhances strategic adaptability. In so doing, we aim to further cultivate discussion on the micro-foundations of strategic management in general and increase interest in the micro-relational foundations of strategic capabilities in particular.
Face Recognition using Two-dimensional Subspace Analysis and PNN

paper, we present an new approach to face recognition based on the combination of feature extraction methods, such as two-dimensional DWT-2DPCA and DWT-2DLDA, with a probabilistic neural networks. This later is used to classify the features matrix extracts for space data created by Two- dimensional Subspace Analysis . The technique 2D-DWT is used to eliminate the illumination ,noise and redundancy of face in order to reduce calculations of the probabilistic neural network operations ,and improve a face recognition system in accuracy and computation time. The proposed approach is tested on ORL and FEI face databases. Experimental results on this databases demonstrated the effectiveness of the proposed approach for face recognition with high accuracy compared with previous methods.
Prediction of hepatotoxicity of traditional Chinese medicine compounds by support vector machine approach

In this study, based on literatures and web databases, 490 hepatotoxic compounds and 598 non-hepatotoxic compounds were selected as a data set for hepatotoxicity discriminative model generation. 1664 molecular descriptors, including physicochemical, charge distribution and geometrical descriptors, were calculated to characterize the molecular structure of liver toxic compounds. The combination of CfsSubsetEval valuation and BestFirst searching was used to choose molecular descriptors for model construction. With the help of support vector machine (SVM), a discriminative model with high accuracy was built. Meanwhile, the accuracy, sensitivity and specificity of this model were all above 80%. Besides, 23 traditional Chinese medicine compounds with hepatotoxicity were regarded as external validation, so as to further verify the model accuracy. Then, the present model was utilized to identify hepatotoxic compounds in Qingkailing injection. The results demonstrated that present study provides a reliable utility for the hepatotoxic compounds prediction in Chinese Medicinal Materials studies.
Can future colour trends be predicted on the basis of past colour trends?: An empirical investigation

A question that has received remarkably little empirical attention is whether colour trends reflect the prevailing sociocultural lifestyle conditions of a society. This is exemplified by such assertions as “the austerity of the War years was accompanied by sombre colours. ” The presumed existence of order to colour consumption and a causal association between it and sociocultural lifestyle conditions provides the theoretical underpinnings to the work of colour forecasting agencies. The present study investigated this question by examining changes in Australian residential interior colours over the twentieth century. Colour palettes were assembled decade by decade and an analysis was undertaken using the NCS system. The results indicate that the main variation during the century was in the hue dimension. However, variation in each of the NCS colour dimensions was greater in the second half of the century. No evidence was found to support the notion of colour cycles or any tangible order to colour consumption. Although some colour palettes could be partially accounted for by developments in colour/materials technology, such influences were short-lived. The picture that emerges does not support the notion that future colour trends can be predicted on the basis of past colour trends. © 2005 Wiley Periodicals, Inc.

Eye Proprioception Used for Visual Localization Only If in Conflict with the Oculomotor Plan

Both the corollary discharge of the oculomotor command and eye muscle proprioception provide eye position information to the brain. Two contradictory models have been suggested about how these two sources contribute to visual localization: (1) only the efference copy is used whereas proprioception is a slow recalibrator of the forward model, and (2) both signals are used together as a weighted average. We had the opportunity to test these hypotheses in a patient (R.W.) with a circumscribed lesion of the right postcentral gyrus that overlapped the human eye proprioceptive representation. R.W. was as accurate and precise as the control group (n = 19) in locating a lit LED that she viewed through the eye contralateral to the lesion. However, when the task was preceded by a brief (<1 s), gentle push to the closed eye, which perturbed eye position and stimulated eye proprioceptors in the absence of a motor command, R.W. 's accuracy significantly decreased compared with both her own baseline and the healthy control group. The data suggest that in normal conditions, eye proprioception is not used for visual localization. Eye proprioception is, however, continuously monitored to be incorporated into the eye position estimate when a mismatch with the efference copy of the motor command is detected. Our result thus supports the first model and, furthermore, identifies the limits for its operation.
A Hybrid Microblog Recommendation Model in Mobile Social Network

Recently, microblogs have emerged as a new open channel of communication for people on the Internet to read, commentate, socialize and so on. With the advent of a huge number of information in microblog spaces, including articles, profile, pictures and other multimedia resources, the "information overload" has become a critical problem for microblog users, which brings bloggers plethora of choices and options available that often varies in quality and may severely affected the recommendation quality. Accordingly, providing microblog users with articles that suit their particular preferences is an important issue. To solve this problem, this paper proposes a novel method integrating social network information and collaborative filtering. A user ranking model based on social network analysis is constructed to estimate the correlations between microblog users, and incorporated into similarity measure for improving the quality of microblog recommendation. Experiments on a real-world dataset are carried out to evaluate the performance of the presented method. The results show that the proposed method outperforms traditional KNN method and improves recommendation quality effectively.
The Shift in Existential Life Situations of Adult Children to Parents with Dementia Relocated to Nursing Homes

Background: Previous research describes spouses and adult children of people with dementia as a homogeneous group using one term: family caregivers. Recent research shows that the needs and experiences of spouses and adult children differ, therefore they cannot be studied as a homogeneous group. Aims: The aim of the study was to describe the shift in existential life situations of adult children of a parent with dementia relocated to nursing homes. Design: This is a qualitative study with an interpretive approach. Methods: Face-to-face interviews were held with 11 adult children aged 48-65 years. The interviews lasted 30–60 minutes and data were analysed using interpretive content analysis. Findings: The adult children described how they experienced their life situation before and after their parents’ relocation. Before relocation they described feelings of powerlessness, loneliness in their responsibilities, loss and guilt. After relocation they had feelings of freedom, ongoing responsibility, living with loss and having a new relationship with death. Conclusion: The most important finding in our study was that adult children developed a different relationship with death than before the parent became affected by dementia. It is essential that healthcare staff understand and address the adult children’s existential life situations and the suffering they are experiencing. Healthcare staff need to be conscious about adult children’s needs for support to address their existential life situations before and after their parents relocate to nursing homes.
Bitter taste receptors confer diverse functions to neurons

Bitter compounds elicit an aversive response. In Drosophila, bitter-sensitive taste neurons coexpress many members of the Gr family of taste receptors. However, the molecular logic of bitter signaling is unknown. We used an in vivo expression approach to analyze the logic of bitter taste signaling. Ectopic or overexpression of bitter Grs increased endogenous responses or conferred novel responses. Surprisingly, expression of Grs also suppressed many endogenous bitter responses. Conversely, deletion of an endogenous Gr led to novel responses. Expression of individual Grs conferred strikingly different effects in different neurons. The results support a model in which bitter Grs interact, exhibiting competition, inhibition, or activation. The results have broad implications for the problem of how taste systems evolve to detect new environmental dangers. DOI: http://dx.doi. org/10.7554/eLife.11181. 001
How well are chain customers known and understood? Exploring customer horizons

The importance of a market orientation as the basis for meeting customer expectations is well known in marketing (Kohli and Jaworski 1990). The basis of this orientation is an understanding of who the customers are and what they want. While it may be expected that all organisations can identify customers through the chain and the final end consumer, the organisations in this case study did not. Many could identify categories of customers and the specific requirements they had, but not the customers’ names. Those organisations downstream and closer to consumers had a greater understanding of who the customers were and what end consumers were looking for. Upstream suppliers were only aware of downstream customers if they had a good reason to such as on-going discussions to meet major quality specifications through the chain. Based on the case study, it is hypothesised that the culture of the organisation has an impact, with some organisations more aware of the importance of understanding customer requirements and having a focus on meeting those where ever possible. In addition, there was some variance in the attitudes of individuals, with purchasing departments more focused on cost minimisation and efficiencies, and marketing more focused on meeting customer requirements and effectiveness. There was also a difference in customer knowledge and understanding at an individual level with those with greater “boundary spanning” roles having greater exposure to customers and therefore having a greater understanding.
The Effect of Disclosure of HIV Status and Sexual Orientation on HIV Prognosis over Four Years

of a thesis at the University of Miami. Several studies have demonstrated the deleterious impact that psychological inhibition can have on psychological and immunological well-being. In the field of HIV, this psychological inhibition has often been operationalized as (a) lack of disclosure of HIV status or, for gay men, (b) disclosure of sexual orientation. However, research on the effect of disclosure on HIV disease status is limited, with only one study having examined both forms of disclosure simultaneously (Strachan et al., 2007). The present study seeks to replicate these findings by investigating whether or not disclosure of HIV status and disclosure of sexual orientation are related to HIV disease progression. The study seeks to extend the prior findings by Strachan et al. (2007) by employing a longer follow-up period (4 years) and using a more generalizable sample. Participants included 177 HIV-infected men and women recruited from hospitals and specialty clinics. At baseline, participants completed self-report measures of disclosure of both HIV status and sexual orientation. Participants also underwent a blood draw to assess CD4 cell count. Questionnaires and blood draws were repeated every 6 months for 4 years. Hierarchical Linear Modeling (HLM) analysis revealed that increased disclosure worries as measured by the HAT-QoL were significantly related to lower CD4 cell counts over a period of four years. Results did not suggest that this relationship was mediated by depressive symptoms or social support. No significant results were found for any other HIV disclosure measures or sexual orientation disclosure measures. Possible reasons for non-significant findings are discussed. Significant findings may warrant close attention to disclosure worries as a person living with HIV begins to disclose their status.
Reactive path planning for autonomous sailboat

Among Autonomous Surface Vehicles (ASV), sailboat robots could be an efficient solution for long term missions and semi-persistent presence in the oceans since they rely on renewable energy like solar and wind energies. However, the steering of such vehicles presents an inherent difficulty since the thrust force heavily rely on the wind (speed and direction) and sail angle as well as on the underlying complex dynamic properties of the ship, mainly due to the aero and hydrodynamic forces acting on the sails and on the hull. In this paper, a new reactive path planning method is proposed, which takes into account the so called no-go zones and turns them into virtual obstacles. A potential field algorithm is then applied to drive the sailboat towards the goal while avoiding obstacles even when the goal is located directly downwind or upwind. Simulations, using a boat specific dynamic simulator, show that the proposed method can successfully drive an autonomous boat to a set of predefined way-points under time varying wind conditions. This method is computationally efficient and is suitable for on-board real-time implementation.
Staying at Home or Working for Pay? Attachment to Modern Mothering Identities

In a context where the pressures of intensive mothering are all-consuming, mothers who work for pay, or mother-workers, face difficult challenges as they attempt to execute the tasks of both parenthood and employment in effective ways. In contrast, stay-at-home mothers, or mother-caregivers, receive reinforcing messages from intensive mothering ideology that they should remain solely focused on meeting their children's everyday needs. Using random sample survey data collected from 3,327 women in mothers’ organizations, I find that while only 18.5% of all mothers have such beliefs regarding whether working for pay is best for children or not, no single mothering identity (mother-worker or mother-caregiver) had a statistically significant relationship with holding such beliefs. However, among the small set of women expressing such beliefs on the value of maternal employment, full-time mother-workers were less likely than mother-caregivers to be able to align their current employment statuses with their preferred paid work preferences.
Magical activism: what happens between the worlds changes the worlds

Witch camps are part of a contemporary philosophical and spiritual movement that encourages social, political and environmental activism. Through an examination of the witch camp experience, this paper highlights the lived intersections of alternative spirituality, community and activism in leisure. Using a critical constructionist, qualitative design, data were collected through participant observation at 2 witch camps, 21 semi-structured intensive interviews, 11 focused interviews and 19 elicited electronic text submissions. Findings illustrate how camp functions as a container for personal and social transformation and provides an ‘antidote’ to alienation and isolation experienced by individuals in the mainstream. The notion of magical activism captures both the experience of the participants and the connection between personal and social transformation in this context. The paper provides empirical evidence of the centrality of leisure and spirituality in engendering responsibility for broader social, political and environmental issues.
Duplication Detection for Image Sharing Systems

Duplication of images is a common occurrence in community based data sharing systems. An image of the same scene, residing as multiple copies in the system, introduces redundancy. This paper describes a novel technique to detect such submissions by matching the Speeded Up Robust Features (SURF) of a query image to the feature set of images in the database, which are pre-computed, dimensionality reduced, and indexed. First, a set of similar images is obtained with their feature key-point correspondences by computing homography. An occurrence of duplication is verified by statistical hypothesis testing, which considers the distribution obtained by inter-key-point Euclidean distance ratios between the corresponding key-points among the query and candidate images.
Julgamentos de plausibilidade e reações emocionais a desculpas

Excuses are frequently used to minimize internal causal attributions when social obligations are not fullfilled. This research investigated judgments of plausibility and emotional reactions to excuses, as well as their acceptability. One hundred and fifty five college students gave their ratings on several scenarios of excuse giving for routine situations. Situations involving motives perceived as legitimate received higher scores of plausibility and positive emotional reactions, followed by situations perceived as controllable, and those of internal causes. Results are discussed in the light of the impression management literature and its efficacy in maintaining informal bondings.
Evaluation of Wireless Network Communication by Autonomous Flight Wireless Nodes for Resilient Networks

The recent development of the society has caused new types of problems such as gaps of depopulation, population aging, and income between urban areas and local areas. The gap of communication networks is also one of the problems, and the poor network circumstance in local areas might affect the future medicare or welfare services by using Information Technology. Also, when there is a natural disaster such as earthquakes or typhoon, these local areas are likely to isolate from others because of disconnection of communication cables or breakdown of network devices. Therefore, this paper proposes Autonomous Flight Wireless Nodes (AFW) for the resilient networks consisted of Delay Tolerant Networks and Never Die Networks, and it is aiming to communicate with isolated areas. In the proposed methods, IP network based drones support data transmission by the autonomous flight with seeking possible wireless stations and sending the message data by the proposed resilient network. Then, the implementations of the proposed methods are introduced, and the results of wireless network conditions by the field experiments are reported in this paper.
Video summarization by video structure analysis and graph optimization

We propose a novel video summarization method that combines video structure analysis and graph optimization. First, we analyze the structure of the video, find the boundaries of video scenes, then we calculate each scene's skimming length based on its structure and content entropy. Second, we define a spatial-temporal dissimilarity function between video shots and model each video scene as a graph, then find each scene's optimal skimming in the graph with dynamic programming. Finally, the whole video's skimming is obtained by concatenating the skimmings of the scenes. Experimental results show that our approach preserves the scene level structure and ensures balanced coverage of the major contents of the original video.
Family-based Gene-by-environment Interaction Studies: Revelations and Remedies

Bias can arise in case-control studies of genotype effects if the underlying population is structured (genetically stratified or admixed). Nuclear–family-based studies enjoy robustness against such bias, provided that inference conditions properly on the parents. Investigators have extended family-based methods to study gene-by-environment interactions, regarding such extensions as retaining robustness. We demonstrate via simulations that, if population structure involves the exposure, nuclear–family-based analyses of gene-by-exposure interaction remain vulnerable to inflated Type I error rates through subtle dependencies that investigators have failed to appreciate. Motivated by the Two Sister Study, an ongoing study of families affected by young-onset breast cancer, we consider a design that supplements the case-parents design with a sibling who is not genotyped but provides exposure data. If, in the population at large, inheritance is Mendelian and genotypes do not influence propensity for exposure, then this 4-person (or tetrad) structure permits the study of genetic effects, exposure effects, and genotype-by-exposure interactions. We show for a dichotomous exposure that, when exposure of an unaffected sibling is available, a modification to the analysis of case-sib or tetrad data re-establishes robustness for tests of multiplicative gene-by-environment interaction. We also use simulations to assess the power for detecting interaction across a range of scenarios, designs, and analytic methods.
Radius-Distance Based Semi-Supervised Algorithm

in order to improve the accuracy and efficiency of directly use of the K-Means clustering for semi-supervised learning, the paper proposes a new semi-supervised learning algorithm based on Radius-Distance. In the algorithm, according to Radius, farthest distance of sample to the cluster center of unlabelled samples using K-Means, and Distance, from cluster center of unlabelled samples to center of labeled samples, a small amount of unlabeled data are selected to aid training learning. Experimental results on the Kddcup'99 demonstrate that the advantages of proposed algorithm over the K-Means method and S3VM.
