Direction-of-Arrival Estimation of Virtual Array Signals Based on Doppler Effect

The estimation accuracy of direction-of-departure (DOD) and direction-of-arrival (DOA) is reduced because of Doppler shifts caused by the high-speed moving sources. In this paper, an improved DOA estimation method which combines the forward-backward spatial smoothing (FBSS) technique with the MUSIC algorithm is proposed for virtual MIMO array signals in high mobility scenarios. Theoretical analysis and experiment results demonstrate that the resolution capability can be significantly improved by using the proposed method compared to the MUSIC algorithm for the moving sources with limited array elements, especially the DOA which can still be accurately estimated when the sources are much closely spaced.
Allergic to hope: Angry resistant attachment and a one-person psychology within a two-person psychological system

Following on from earlier writing about individuals with an avoidant attachment style, STAN TATKIN explores the characteristics of individuals with an ‘angry resistant’ attachment style, in particular, within the context of couple therapy. While the primary issue for ‘avoidant’ individuals is dependency, the primary issue for ‘angry resistant’ individuals is dashed hope, leading to anticipatory disappointment and negativism, and a perpetual cycle of relationship failure. Discusssion of these issues draws on attachment theory, arousal regulation theory, and recent advances in developmental neurobiology. Practical applications for the clinician include the use of characteristic patterns of expression, interpersonal contact, mode of communication, and attitudinal predisposition in the assessment of angry resistant individuals, as well as the engagement of the individual’s partner as a means to help the angry resistant individual overcome his or her allergy to hope. TATKIN concludes that couple therapists, who understand the regulatory bias and basic neurobiological make-up of their angry resistant clients, have an advantage when it comes to moving these individuals toward a satisfying and long-lasting relationship based on a two-person psychological system.
Lrp1/LDL Receptor Play Critical Roles in Mannose 6‐Phosphate‐Independent Lysosomal Enzyme Targeting

Most lysosomal enzymes require mannose 6‐phosphate (M6P) residues for efficient receptor‐mediated lysosomal targeting. Although the lack of M6P residues results in missorting and hypersecretion, selected lysosomal enzymes reach normal levels in lysosomes of various cell types, suggesting the existence of M6P‐independent transport routes. Here, we quantify the lysosomal proteome in M6P‐deficient mouse fibroblasts (PTki) using Stable Isotope Labeling by Amino acids in Cell culture (SILAC)‐based comparative mass spectrometry, and find unchanged amounts of 20% of lysosomal enzymes, including cathepsins D and B (Ctsd and Ctsb). Examination of fibroblasts from a new mouse line lacking both M6P and sortilin, a candidate for M6P‐independent transport of lysosomal enzymes, revealed that sortilin does not act as cargo receptor for Ctsb and Ctsd. Using fibroblast lines deficient for endocytic lipoprotein receptors, we could demonstrate that both LDL receptor and Lrp1 mediate the internalization of non‐phosphorylated Ctsb and Ctsd. Furthermore, the presence of Lrp1 inhibitor increased the secretion of Ctsd from PTki cells. These findings establish Lrp1 and LDL receptors in M6P‐independent secretion‐recapture targeting mechanism for lysosomal enzymes.
Concordance between periconceptional folic acid supplementation and Canadian Clinical Guidelines.

BACKGROUND In 2007, the Society of Obstetricians and Gynaecologists of Canada (SOGC) introduced new guidelines on periconceptional folic acid supplementation. OBJECTIVES To evaluate the concordance between the SOGC guidelines and actual vitamin/folic acid supplementation, and to identify maternal determinants of concordant folic acid use.MethodsFrom May to July 2010, pregnant women attending the outpatient clinic at CHU Ste-Justine in Montreal were surveyed to assess use of folic acid. Data on socio-demographic factors, lifestyles, family and personal medical history, and periconceptional folic acid supplementation were collected using a self-administrated questionnaire. Concordance between maternal reported intake of folic acid and SOGC guidelines was estimated accounting for pregnancy history, comorbidities, and lifestyles. RESULTS A total of 361 eligible women gave informed consent; of these, 97 (27%) had periconceptional folic acid supplementation intake that was concordant with guidelines. Women with no personal history of neural tube defects (NTDs) were the most concordant with guidelines (36%), followed by women with a previous child with NTD (26%), and women with health risk factors for NTDs (18%). Women who smoked and drank alcohol had the lowest concordance with guidelines (4%). Women with planned pregnancies and higher income were more likely to be concordant with guidelines; whereas, smokers, alcohol and recreational drug user and women with health risk for NTDs were less likely to be concordant. CONCLUSIONS Concordance with clinical guidelines was low, even for women with a history of NTDs. Our findings highlight the need for public health programs to inform women to consume folic acid every day before and during pregnancy.
Toward a relational economic geography

In this paper, we argue that a paradigmatic shift is occurring in economic geography toward a relational economic geography. This rests on three propositions. First, from a structural perspective economic actors are situated in contexts of social and institutional relations. Second, in dynamic perspective economic processes are path-dependent, constrained by history. Third, economic processes are contingent in that the agents' strategies and actions are open-ended. Drawing on Storper's holy trinity, we define four ions as the basis for analysis in economic geography: organization, evolution, innovation, and interaction. Therein, we employ a particular spatial perspective of economic processes using a geographical lens. Copyright 2003, Oxford University Press.
Is less more? Confirmatory factor analysis of the Attachment Style Questionnaires

Few psychometric studies have confirmed the factor structure of the Attachment Style Questionnaire (ASQ) (Feeney, Noller, & Hanrahan, 1994), a widely used self-report attachment measure. Moreover, no study has formally investigated the factor structure of the ASQ’s short form (ASQ-SF) proposed by Alexander, Feeney, Hohaus, and Noller (2001). The aim of the present study was to validate the factor structures of the ASQ and ASQ-SF, and to identify the more parsimonious measure. In two studies, a nested factor model provided the best fit, the ASQ-SF was the more parsimonious measure, and results were consistent across age and gender groups. Theoretical and clinical implications are discussed.
On Loops Representing Elements of the Fundamental Group of a Complete Manifold with Nonnegative Ricci Curvature

This paper concerns complete noncompact manifolds with nonnegative Ricci curvature. Roughly, we say that M has the loops to infinity property if given any noncontractible closed curve, C, and given any compact set, K, there exists a closed curve contained in M\K which is homotopic to C. The main theorems in this paper are the following. Theorem I: If M has positive Ricci curvature then it has the loops to infinity property. Theorem II: If M has nonnegative Ricci curvature then it either has the loops to infinity property or it is isometric to a flat normal bundle over a compact totally geodesic submanifold and its double cover is split. Theorem III: Let M be a complete riemannian manifold with the loops to infinity property along some ray starting at a point, p. Let D containing p be a precompact region with smooth boundary and S be any connected component of the boundary containing a point, q, on the ray. Then the map from the fundamental group of S based at q to the fundamental group of Cl(D) based at p induced by the inclusion map is onto.
Underdetermined Joint Blind Source Separation of Multiple Datasets

In this paper, we tackle the problem of jointly separating instantaneous linear underdetermined mixtures of latent sources from multiple data sets, where the number of sources exceeds that of observations in each data set. Currently available blind source separation (BSS) methods, including joint BSS (JBSS) and underdetermined BSS (UBSS), cannot address this underdetermined problem effectively. We exploit the second-order statistics of observations, and present a novel BSS method, referred to as underdetermined joint BSS for multiple data sets (UJBSS-m), as a generalization of our previous work on two data sets. In this paper, the cross correlation between each pair of data sets is modeled by a third-order tensor in which a set of spatial covariance matrices corresponding to different time delays are stacked. Considering the latent common structure of these constructed tensors, the mixing matrices are jointly estimated via joint canonical polyadic decomposition of these specialized tensors. Furthermore, we recover the sources from each data set separately based on the estimated mixing matrices. Simulation results demonstrate that the proposed UJBSS-m method yields superior performances when compared with commonly used single-set UBSS and JBSS methods.
F-actin-binding protein drebrin regulates CXCR4 recruitment to the immune synapse

The adaptive immune response depends on the interaction of T cells and antigen-presenting cells at the immune synapse. Formation of the immune synapse and the subsequent T-cell activation are highly dependent on the actin cytoskeleton. In this work, we describe that T cells express drebrin, a neuronal actin-binding protein. Drebrin colocalizes with the chemokine receptor CXCR4 and F-actin at the peripheral supramolecular activation cluster in the immune synapse. Drebrin interacts with the cytoplasmic tail of CXCR4 and both proteins redistribute to the immune synapse with similar kinetics. Drebrin knockdown in T cells impairs the redistribution of CXCR4 and inhibits actin polymerization at the immune synapse as well as IL-2 production. Our data indicate that drebrin exerts an unexpected and relevant functional role in T cells during the generation of the immune response.
Interventions that effect change in psychotherapy: A model based on infant research

At the present time we are experiencing wide interest in rethinking and reformulating the conceptual and the clinical bases for understanding the way in which change takes place in psychotherapy. Almost daily one encounters new books, journal articles, and conferences that are directed toward this goal. We are moving psychology from traditional psychoanalytic language and conceptual frameworks to new vocabularies of chaos theory and nonlinear dynamic systems as we seek to describe “process” in the therapeutic interaction. Discussion has moved from explanations of change in the psychotherapeutic process as based on insight, as the unconscious becomes conscious through effective interpretation, to explanations described in terms of shifts in the organization of consciousness. These shifts in consciousness are brought about through moments of shared awareness—Tronick’s hypothesized dyadic states of consciousness—between patient and therapist as they experience “moments of meeting” within their “intersubjective environment. ” With these changes in explanation, we are aligning our thinking with new information about the way the brain works in its construction of perception and memory and the way brain morphology becomes shaped by early experience. We are beginning to speak of “themes of organization” in the construction of expectancy for the flow of sequence and consequence in the stream of the recurrent daily events that construct one’s
Relationship of human papilloma virus multiple genotype infection with patient's age and type of cervical lesion.

PURPOSE OF INVESTIGATION To document the prevalence of infection by multiple genotypes of the human papilloma virus (HPV) in patients with cervical pathology in a study population, and to determine the relationship between multiple genotype infection, age of the patient, and the type of cervical pathology. MATERIALS AND METHODS Prospective, cross-sectional descriptive study. A total of 1,007 patients were recruited among women seen at the cervical pathology clinic of Sant Joan de Déu University Hospital in Barcelona (Spain) between January 2003 and March 2011. Statistical analyses were done with SPSS v.19 software. Differences between groups were considered statistically significant atp < 0.05. RESULTS There was 28.3% of the women (286 cases) that were infected by multiple HPV genotypes. The mean number of genotypes identified was 2.52 (range 2 to 8). Mean age of the patients with multiple genotype infection was 32.31 years, and mean age of the patients with single genotype infection was 37.27 years (p < 0.001). The prevalence of infection by multiple HPV genotypes was 28% in patients with cervical intraepithelial neoplasia grade 1 (CIN 1) and 33% in patients with grade CIN 2-3 lesions, and both prevalence rates were significantly higher than in patients with carcinoma (20%) (p = 0.03). CONCLUSIONS In the present study population the authors found no evidence of higher prevalence of multiple HPV genotype infection in women with carcinoma. Age of women with multiple infection was lower than those with single infection.
Computer-aided Game Analysis of Net Sports in Preparation of Chinese Teams for Beijing Olympics

In the preparation of the 2008 Beijing Olympics, the Technique and Tactic Research Center of Shanghai University of Sport developed a series of softwares and conducted a large number of game analyses for national teams of table tennis, badminton, tennis and volleyball, and the results proved to be quite effective. Based on the methods of data collection and computation, the present paper classifies the computer-aided game analysis into non-systematic analysis, systematic analysis and intelligent analysis. The non-systematic analysis is mainly conducted by collecting the technique and tactic attributes of the last stroke in every rally (such as the technique, position, striking sequence, scoring and losing). The strength of non-systematic analysis lies in its quick feedback of the results to the coaches and players, but this method may fail to obtain the technical and tactical attributes of other strokes. The systematic analysis is done according to the strictly defined technical and tactical observation system by collecting all the technical and tactical attributes of every stroke of the player in the competition (match, set, score, player, striking technique, striking position, striking placement, technical state, effect, scoring and losing). It can provide complete information of the techniques and tactics and conduct different types of detailed analysis, but due to the heavy workload of data collection for systematic analysis, it may need longer time to provide feedback to coaches and players. Intelligent analysis is the method based on data mining and artificial neural network techniques. Data mining (association analysis) could reveal the association characteristics between several consecutive strokes or stroke positions or placements and scoring or losing. It could help coaches understand better the characteristics of the techniques and tactics and thus is likely to become one of the major methods in future ball game analysis. Through automatic training with only the input data (such as technique and tactic indexes) and output data (such as winning probability), the artificial neural network can construct models with very high precision. Therefore, further investigation in this field is necessary and worthwhile.
PR Bunnies Caught in the Agency Ghetto? Gender Stereotypes, Organizational Factors, and Women's Careers in PR Agencies

Against the background of the high feminization of the German agency sector, this article investigates 2 specific factors that help explain women's careers in public relations agencies: gender stereotypes and the organizational context. We present parts of a recent German explorative study: Long interviews were conducted with 13 female public relations experts to explain their view on women's situation in public relations in general and to describe their own careers. Findings reveal the evolution of a “PR bunny” stereotype that adds a negative touch to the female image as “natural born communicators. ” Furthermore, our results support the argument that women seem to prefer (a) the organizational culture of public relations agencies, (b) agency-specific job tasks, and (c) agency-specific work processes. Possible consequences for practitioners and the profession are discussed.
Barossa Dreaming: Imagining Place and Constituting Cuisine in Contemporary Australia

Regional cuisines have become a prominent feature in the consumer landscape of modernised societies. This article describes how a regional cuisine is being socially constituted in the Barossa Valley, one of the most important wine-growing areas in Australia. Initially, I detail how small farmers, winegrowers and other entrepreneurs idealise the Barossa landscape and fabricate the heritage that is integral to the idea of a distinctive cuisine. This is followed by examination of how the notion of Barossa food as having distinctive qualities because of the artisanal ways it is produced is constantly being elaborated by the valley's small-scale enterprises. Lastly, I explore the contribution of wider influences to this cultural process, from the role played by an internationally recognised celebrity chef through to the recent arrival of the Slow Food movement. Local factors and global influences contribute to the social manufacture of the Barossa's regional cuisine, the overall appeal of which to middle class consumers is as much cultural as it is culinary.
The Divine Side of Enterprise

This article analyzes the past, the present, and the future of business institution in society in terms of its management approaches by using the framework of human evolution, and discovers a trend that explains three paradigms in business management that have been witnessed so far. Extending the trend, it projects another two paradigm shifts to take place in future, and establishes that the business management practice is going to evolve further where it will turn from its present status of ‘result-oriented management’to ‘process-oriented management’ in terms of its focus, or in other words, it will evolve from ‘professional management’ to ‘ethical management’ in terms of its underlying philosophy. As a result, the business enterprise will evolve from its present form of economic organization to a humane organization, and further up to a divine organization. Expressed the other way round, the business institution that had kicked off as an industrial organization has got transformed to a human organization by now; however, in the future, it will further evolve to its final level of a divine organization.
Processing Depth, Elaboration of Encoding, Memory Stores, and Expended Processing Capacity.

The divided attention technique introduced by W. A. Johnston was used to assess the effects of several factors on expended processing capacity, which was indexed by the slowing of simple reaction time during the concurrent processing of other information. Expended processing capacity was greater when information was retrieved from secondary memory than from primary memory; when processing was of a deep, semantic nature than when it was shallow and physical; and it was greater when processing was more elaborate. The evidence thus suggests that expended processing capacity accurately reflects important aspects of memorial functioning. The relevance of these findings to limited capacity theories is discussed. The experiments reported in this article are concerned with the effects of several variables (memory store, depth of processing, and elaboration of processing) on expended processing capacity. There are valid theoretical reasons for investigating these issues: If people have limited processing capacity, then it is obviously of importance to establish the relative demands on that processing capacity imposed by different processing activities. To obviate semantic confusion, some of the key concepts referred to in this article will be defined at this point. We follow Johnston and Heinz (1978) in defining processing capacity as "the limited pool of energy, resources, or fuel by which some cognitive operations or processes are mobilized and maintained" (p. 422). We assume that tasks differ in terms of the demands they make on this processing capac
Promoting self-regulated learning to improve achievement: A case study in higher education

Abstract The aim of this article is to report on a study conducted to assess the effect of an intervention programme to improve SRL and the achievement of a group of poorly performing undergraduate students at the Tshwane University of Technology. SRL was used as theoretical framework. The case study reports on 20 Engineering students who attended learning skills intervention sessions and wrote a college version of the learning and study strategies inventory (LASSI) pre-test and post-test. The intervention consisted of 12 workshop sessions presented over a period of three months. The LASSI pre-test showed that the group scored below the 50th percentile on four scales (anxiety, attitude, selecting main ideas and test-taking strategies). Observed improvements in the post-test scores of the LASSI scales for seven out of ten scales were statistically significant. The students’ academic achievements also improved. The findings are important for improving student success and throughput in South African higher education.
Asserting Property Rights: Knowledge Codification in the Professional Service Firm

Despite the frequent assertion that knowledge management is an important strategic activity, there have been relatively few empirical studies of the processes involved in this, particularly in knowledge intensive firms. The paradox inherent to codification projects is that they are dependent on professional staff willingly transferring the knowledge that often underpins their status. My purpose in this article is to examine whether and how this paradox is resolved by presenting a case study of a knowledge codification project under- taken by a professional service firm (PSF). I argue that the successful assertion of property rights relates, ironically, to its limitation. Codification takes place in a way that does not nullify the consultants’ expert role in front of the client. That there appear to be limits to how far such a reductive exercise can capture the activities of the consultants has implications for grammatical models that aim to describe and theorize about organizational processes or sequences of actions. I discuss these in the latter part of the article.
Sympathoadrenal and hemodynamic effects of isoflurane, halothane, and cyclopropane in dogs.

The sympathoadrenal response and its relation to the hemodynamic effects of isoflurane, halothane, and cyclopropane were studied in ten dogs. Each animal was used as its own control. At weekly intervals, the changes in plasma epinephrine and norepinephrine concentrations and in cardiac output (), wh
