A Novel Direct Position Determination Algorithm for Orthogonal Frequency Division Multiplexing Signals Based on the Time and Angle of Arrival

Compared with conventional two-step localization algorithms which are implemented by initially estimating localization parameters and then calculating the target position, the performance of direct position determination (DPD) algorithm is superior in terms of high estimation accuracy and strong resolution capability. DPD algorithms can make full use of the characteristics of signals to improve positioning performance. Using this localization mechanism as basis, this study develops a novel DPD algorithm that profits from the characteristics of orthogonal frequency division multiplexing (OFDM) signals based on the time and angle of arrival. First, the DPD optimization model is constructed based on maximum likelihood criterion and the characteristic of multiple carrier modulation technique of OFDM signals. Then, an extended subspace data fusion-based DPD algorithm is developed by constructing and decomposing the extended covariance matrices. The algorithm fuses the extended subspace data to estimate the target position without calculating the intermediate variables, which is less complex and more efficient. These properties can avoid the limitations of two-step algorithms. The last but important result is a derivation of the closed-form expression of Cramer-Rao lower bound (CRLB) on the position estimation variance for OFDM sources. Simulation results show that, the algorithm proposed in this paper outperforms existing DPD algorithms and conventional two-step localization algorithms. Especially under the condition of low signal-to-noise ratio, its localization accuracy is close to the CRLB.
The Place of Learning within the Human Development System: A Developmental Contextual Perspective

Within developmental contextualism. the basic process of human development involves changing relations between the developing person and his or her changing, multilevel context. Accordingly, the functions associated with any one level of organization are quite distinct from the process of development. Learning is a case in point. Learning is a function of the person and has its locus at the individual-psychological level of organization. Both more molecular and more molar levels of organization have their own focal functions and, as with learning, these functions play necessary but, by themselves, insufficient roles in texturing the changing developmental system. Learning is no more or no less important than any other focal function at any level of organization. If learning has an influence on other levels, it does so only through being part of an integrated system of multilevel relations.
TEORÍAS IMPLÍCITAS DEL LIDERAZGO MASCULINO Y FEMENINO SEGÚN ÁMBITO DE DESEMPEÑO

Research was conducted to find if exist differences in implicit leadership theories (ILTs) about masculine and feminine leadership according work context (enterprise, academic and political). Besides, we look for differences in feminine ILTs according work context, and sex of the participant. Participate 441 adults (50,3% male; 49,7% female). The data collection was realized by a survey designed ad-hoc, in which the participants were requested to describe a male/ female leader according work context. The obtained results do not evidence differences in masculine and feminine ILTs according work context, but show differences in ILTs considered globally. Besides we found differences in feminine ILTs according work context, and sex of the participant.
Ultrastructural localization of alpha-actinin and filamin in cultured cells with the immunogold staining (IGS) method

Monospecific antibodies to chicken gizzard actin, alpha-actinin, and filamin have been used to localize these proteins at the ultrastructural level: secondary cultures of 14-d-old chicken embryo lung epithelial cells and chicken heart fibroblasts were briefly lysed with either a 0.5% Triton X-100/0.25% glutaraldehyde mixture, or 0.1% Triton X-100, fixed with 0.5% glutaraldehyde, and further permeabilized with 0.5% Triton X-100, to allow penetration of the gold-conjugated antibodies. After immunogold staining (De Mey, J., M. Moeremans, G. Geuens, R. Nuydens, and M. De Brabander, 1981, Cell Biol. Int. Rep. 5:889-899), the cells were postfixed in glutaraldehyde-tannic acid and further processed for embedding and thin sectioning. This approach enabled us to document the distribution of alpha-actinin and filamin either on the delicate cortical networks of the cell periphery or in the densely bundled stress fibers and polygonal nets. By using antiactin immunogold staining as a control, we were able to demonstrate the applicability of the method to the microfilament system: the label was distributed homogeneously over all areas containing recognizable microfilaments, except within very thick stress fibers, where the marker did not penetrate completely. Although alpha-actinin specific staining was homogeneously localized along loosely-organized microfilaments, it was concentrated in the dense bodies of stress fibers. The antifilamin-specific staining showed a typically spotty or patchy pattern associated with the fine cortical networks and stress fibers. This pattern occurred along all actin filaments, including the dense bodies also marked by anti-alpha-actinin antibodies. The results confirm and extend the data from light microscopic investigations and provide more information on the structural basis of the microfilament system.
Sufficient Conditions for First-Order and Datalog Rewritability in ELU

We study the problem of answering instance queries over non-Horn ontologies by rewriting them into Datalog programs or FirstOrder queries (FOQs). We consider the basic non-Horn language ELU , which extends EL with disjunctions. Both Datalog-rewritability and FOrewritability of instance queries have been recently shown to be decidable for ALC ontologies (and hence also for ELU); however, existing decision methods are mainly of theoretical interest. We identify two fragments of ELU for which we can compute Datalog-rewritings and FO-rewritings of instance queries, respectively, by means of a resolution-based algorithm.
Cell Origami: Self-Folding of Three-Dimensional Cell-Laden Microstructures Driven by Cell Traction Force

This paper describes a method of generating three-dimensional (3D) cell-laden microstructures by applying the principle of origami folding technique and cell traction force (CTF). We harness the CTF as a biological driving force to fold the microstructures. Cells stretch and adhere across multiple microplates. Upon detaching the microplates from a substrate, CTF causes the plates to lift and fold according to a prescribed pattern. This self-folding technique using cells is highly biocompatible and does not involve special material requirements for the microplates and hinges to induce folding. We successfully produced various 3D cell-laden microstructures by just changing the geometry of the patterned 2D plates. We also achieved mass-production of the 3D cell-laden microstructures without causing damage to the cells. We believe that our methods will be useful for biotechnology applications that require analysis of cells in 3D configurations and for self-assembly of cell-based micro-medical devices.
Evaluating the Michigan SENSOR Surveillance Program for work-related asthma.

BACKGROUND Most Occupational Safety and Health Administration (OSHA) inspections are based on employee complaints or targeting of industry groupings. Limited use has been made of illness data to target inspections and evaluation of such targeting is even more limited. METHODS This study compared 545 Michigan OSHA (MIOSHA) inspections performed as follow up to reports of work-related asthma (WRA) with 12,268 non-disease initiated OSHA inspections performed during the same time period (1989-2002). RESULTS SENSOR asthma inspections were more likely to be conducted in larger, unionized employers. Although the likelihood of citations ( approximately 50%), type of citation, and monetary penalties ( approximately 30%) were not different between disease and non-disease initiated inspections, the number of citations and amount of monetary penalties were less in disease initiated inspections. Citations and penalties were more likely for small as compared to large employers, and were less likely at unionized worksites. CONCLUSIONS Even without the availability of specific standards for agents that cause WRA, inspections triggered by a WRA index case are very much like other inspected worksites in terms of the prevalence of violations observed at the worksite. The advisability of making referrals to OSHA and additional ways to evaluate the effectiveness of this type of intervention model are discussed.
On the Complexity of Three-Dimensional Channel Routing (Extended Abstract)

The 3-D channel routing is a fundamental problem on the physical design of 3-D integrated circuits. The 3-D channel is a 3-D grid G and the terminals are vertices of G located in the top and bottom layers. A net is a set of terminals to be connected. The objective of the 3-D channel routing problem is to connect the terminals in each net with a Steiner tree (wire) in G using as few layers as possible and as short wires as possible in such a way that wires for distinct nets are disjoint. This paper shows that the problem is intractable.

Integrated narrative analysis in multilingual aphasia: The relationship among narrative structure, grammaticality, and fluency

Background: Amid robust evidence for the efficacy of language treatment in aphasia, equivocal results have been reported for the generalisation of treatment effects to items and tasks not practised during therapy. Moreover, measuring generalisation using functional language production has proven challenging, especially in the context of multilingual aphasia. Aim: In this paper we analysed four domains—discourse structure, sentence structure, instances of linguistic dysfluencies, and lexical choice—in narratives produced following treatment to assess aphasia treatment generalisation within and across languages. Methods & Procedures: Two treatment phases were administered to a trilingual speaker with mild, chronic, non-fluent aphasia, targeting language production. Multiple baseline testing was administered prior to and following each treatment phase and included elicited narrative production in three languages: Hebrew, English, and French. Outcomes & Results: The results demonstrated treatment-related changes in the treated language as well as in the non-treated languages. Positive change was found in narrative structure and in sentence grammaticality. A trade-off pattern between grammaticality and fluency was evident, with higher proportions of grammatical sentences associated with increased instances of linguistic dysfluencies. Within-language and between-language generalisation was observed, especially following the first treatment phase which targeted morphosyntactic structures. Conclusions: We argue for the importance of an integrated analysis of connected language production in the assessment of aphasia treatment efficacy and in multilingual aphasia.
Analysis of Invasiveness of Pneumococcal Serotypes and Clones Circulating in Portugal before Widespread Use of Conjugate Vaccines Reveals Heterogeneous Behavior of Clones Expressing the Same Serotype

ABSTRACT To estimate the invasive disease potential of serotypes and clones circulating in Portugal before extensive use of the seven-valent pneumococcal conjugate vaccine, we analyzed 475 invasive isolates recovered from children and adults and 769 carriage isolates recovered from children between 2001 and 2003. Isolates were serotyped and genotyped by pulsed-field gel electrophoresis, and a selection of isolates were also characterized by multilocus sequence typing. We found that the diversities of serotypes and genotypes of pneumococci responsible for invasive infections and carriage were identical and that most carried clones could also be detected as causes of invasive disease. Their ability to do so, however, varied substantially. Serotypes 1, 3, 4, 5, 7F, 8, 9N, 9L, 12B, 14, 18C, and 20 were found to have an enhanced propensity to cause invasive disease, while serotypes 6A, 6B, 11A, 15B/C, 16F, 19F, 23F, 34, 35F, and 37 were associated with carriage. In addition, significant differences in invasive disease potential between clones sharing the same serotype were found among several serotypes, namely, 3, 6A, 6B, 11A, 14, 19A, 19F, 22F, 23F, 34, and NT. This heterogeneous behavior of the clones was found irrespective of the serotype's overall invasive disease potential. Our results highlight the importance of the genetic background when analyzing the invasive disease potential of certain serotypes and provide an important baseline for its monitoring following conjugate vaccine use. Continuous surveillance should be maintained, and current research should focus on uncovering the genetic determinants that contribute to the heterogeneity of invasive disease potential of clones sharing the same serotype.
A Double-blind, Randomised, Placebo-controlled Trial of Cytisine for Smoking Cessation in Medium-dependent Workers

Among many studies on cytisine only a few have been controlled trials, and the aim of this study was to assess the efficacy of cytisine in a randomized controlled double-blind trial compared to placebo in medium-dependent smoking men working in mining industry. Materials and methods:171 middle-aged smokers were randomised to either cytisine (25-days regimen) or placebo; both groups received individual counseling with brochure. Self-reported continuous abstinence was assessed at 8 and 26 weeks. Results: At the end of week 8 there were no differences in number of abstinent subjects, but at 26 weeks 10.6% of subjects were abstinent in cytisine group compared to 1.2% in placebo ( p= .01). In both groups, we did not find any weight increase, but quality of life improved in both groups, and physical and social functioning improved in cytisine group. Conclusions: Cytisine may be an effective medication to help smokers quit even for those working in difficult working conditions with high relapse rate.
Contracts in the English NHS: Market levers and social embeddedness

Abstract This paper draws parallels between the market trend in the English NHS and Polanyi’s (1957) The Great Transformation: The political and economic origins of our time, Beacon Press: Boston (originally published in 1944 in the United States as The Great Transformation, Rinehart: and Co: New York, and in 1945 in England as Origins of our time, Gollancz: London) account of how the rise of markets provokes a self-protective counter-reaction that tries to re-embed economic relations in social relations. We report findings from a qualitative study of NHS contracting, which examines the recent move to harder-edged contracts with greater use of financial penalties and incentives. In practice, use of these techniques tended to be confined to nationally-mandated sections of the contract rather than emerging from local bilateral agreements, and when things went wrong the parties relied more on cooperative behaviour than on the provisions of the contract to find solutions. Making the current contracting system work depended more on existing relational networks than on the incentive structures created by recent ‘marketisation’ initiatives, but the inability of the market to evolve as expected has encouraged policy makers to publish plans for further radical reforms.
Scale of Death Anxiety (SDA): Development and Validation

This study developed and validated a new measure to assess the death anxiety (i.e., Scale of Death Anxiety, SDA) on an individual’s somatic, cognitive, emotional, and behavioral reactions from a symptomatic perspective in Chinese youth samples. Following a systematic process, a four-factor structure of the SDA was identified through principle components analysis and confirmatory factor analysis that revealed four aspects of death anxiety: Dysphoria, Death Intrusion, Fear of Death, and Avoidance of Death. The results of this study indicate that the SDA has a clear factor structure and good psychometric properties. The SDA supports death anxiety as a multidimensional construct, and the foundational role of fear of death in the generation of death anxiety. This scale is valuable and beneficial to research on death anxiety. This study makes a significant contribution to the literature because the SDA is the first assessment of death anxiety to include the constructs of dysphoria and somatic symptoms. And the potential clinical practice of the SDA was discussed.
Processor Capacity Reserves for Multimedia Operating Systems

Multimedia applications have timing requirements that cannot generally be satisfied using time-sharing scheduling algorithms and system structures. To effectively support these types of programs, operating systems must support processor capacity reservation. A capacity reservation and enforcement mechanism isolates programs from the timing and execution characteristics of other programs in the same way that a memory protection system isolates programs from memory access by other programs. In this paper, we characterize the timing requirements and processor capacity reservation requirements for multimedia applications, we describe a scheduling framework to support reservation and admission control, and we introduce a novel reserve abstraction, specifically designed for the microkernel architecture, for controlling processor usage.
Lymphocytes from Chronically Stressed Mice Confer Antidepressant-Like Effects to Naive Mice

We examined whether cells of the adaptive immune system retain the memory of psychosocial stress and thereby alter mood states and CNS function in the host. Lymphocytes from mice undergoing chronic social defeat stress or from unstressed control mice were isolated and adoptively transferred into naive lymphopenic Rag2−/− mice. Changes in affective behavior, hippocampal cell proliferation, microglial activation states, and blood cytokine levels were examined in reconstituted stress-naive mice. The mice receiving lymphocytes from defeated donors showed less anxiety, more social behavior, and increased hippocampal cell proliferation compared with those receiving no cells or cells from unstressed donors. Mice receiving stressed immune cells had reduced pro-inflammatory cytokine levels in the blood relative to the other groups, an effect opposite to the elevated donor pro-inflammatory cytokine profile. Furthermore, mice receiving stressed immune cells had microglia skewed toward an anti-inflammatory, neuroprotective M2-like phenotype, an effect opposite the stressed donors' M1-like pro-inflammatory profile. However, stress had no effect on lymphocyte surface marker profiles in both donor and recipient mice. The data suggest that chronic stress-induced changes in the adaptive immune system, contrary to conferring anxiety and depressive behavior, protect against the deleterious effects of stress. Improvement in affective behavior is potentially mediated by reduced peripheral pro-inflammatory cytokine load, protective microglial activity, and increased hippocampal cell proliferation. The data identify the peripheral adaptive immune system as putatively involved in the mechanisms underlying stress resilience and a potential basis for developing novel rapid-acting antidepressant therapies.
An integrable shallow water equation with peaked solitons.

We derive a new completely integrable dispersive shallow water equation that is bi-Hamiltonian and thus possesses an infinite number of conservation laws in involution. The equation is obtained by using an asymptotic expansion directly in the Hamiltonian for Euler's equations in the shallow water regime. The soliton solution for this equation has a limiting form that has a discontinuity in the first derivative at its peak.

Caring about Caring: What Adults Can Do to Promote Young Children's Prosocial Skills.

As reflected in these teAchers’ comments, many early childhood educators are seriously concerned about bullying and aggression. Children’s negative social behaviors also dominate the media and are the focus of much current research. Recent studies result in some progress in understanding the early origins and harmful effects of physical and relational aggression (Crick et al. 2006) and designing interventions to reduce its occurrence (Ostrov et al. 2009). It is equally important to nurture positive alternatives—children’s prosocial feelings and behavior toward others. Nancy Eisenberg, a leading researcher in the area of prosocial behavior, and her coauthors describe prosocial behavior as “voluntary behavior intended to benefit another” (Eisenberg, Fabes, & Spinrad 2006, 646). This article draws extensively on their excellent literature review. The second author of this article (Taylor) conducted a survey and face-toface interviews about prosocial development with early childhood teachers and directors in the spring of 2010. In the interviews, early childhood educators used terms such as empathy, sharing, compassion, helping others, compromise, respect for others, and hugging other children to describe prosocial behavior in young children (Taylor 2010). Prosocial behaviors might also include cooperating, including others in play, giving a compliment, and comforting a child who is upset (Honig 2004; Ramaswamy & Bergin 2009). One word, voluntary, is especially important in Eisenberg’s definition of prosocial behavior. If children are forced to “be nice and share” or told to “say you’re sorry,” then their behavior is not voluntary and cannot be considered prosocial. The research we share in this article highlights many ways that children’s prosocial development can be actively promoted without being forced.
Evaluation Methods for Musical Audio Beat Tracking Algorithms

A fundamental research topic in music information retrieval is the automatic extraction of beat locations from music signals. In this paper we address the under-explored topic of beat tracking evaluation. We present a review of existing evaluation models and, given their strengths and weaknesses, we propose a new method based on a novel visualisation for beat tracking performance, the beat error histogram. To investigate the properties of evaluation methods we undertake a large scale beat tracking experiment. We conduct experiments using a new annotated test database which we make available to the research community. We demonstrate that the choice of evaluation method can have a significant impact on the relative performance of different beat tracking algorithms. On this basis we make a set of recommendations for comparative beat tracking experiments.
