A Coplanar Waveguide Fed Two Arm Archimedean Spiral Slot Antenna With Improved Bandwidth

A compact wideband circularly polarized (CP) printed antenna design is presented in this communication. The proposed antenna consists of two Archimedean spiral slots, loaded with two chip resistors and fed by a coplanar waveguide (CPW) transmission line. The antenna is situated in one plane and fed without using an external balun or a matching network. The antenna has wideband input impedance bandwidth with circular polarization (CP), and broad beamwidth radiation pattern over 1.6:1 bandwidth. The study has shown that the proposed antenna is capable of improving the CP bandwidth and reducing the overall antenna size.
Secure Communications via Cooperating Base Stations

A novel approach for ensuring confidential communications over infrastructure-based wireless networks is proposed and analyzed from an information-theoretic standpoint. The technique leverages the high-capacity backbone connecting the base stations and prescribes appropriate scheduling of uplink/downlink transmissions in order to create intentional interference without loss of power or spectral efficiency. Analysis is carried out for Gaussian channels and numerical results are provided for fading channels with partial channel state information, showing the promising performance advantages of the considered strategy.
The short-term effects of an integrated care model for the frail elderly on health, quality of life, health care use and satisfaction with care

Purpose This study explores the short-term value of integrated care for the frail elderly by evaluating the effects of the Walcheren Integrated Care Model on health, quality of life, health care use and satisfaction with care after three months. Intervention Frailty was preventively detected in elderly living at home with the Groningen Frailty Indicator. Geriatric nurse practitioners and secondary care geriatric nursing specialists were assigned as case managers and co-ordinated the care agreed upon in a multidisciplinary meeting. The general practitioner practice functions as a single entry point and supervises the co-ordination of care. The intervention encompasses task reassignment between nurses and doctors and consultations between primary, secondary and tertiary care providers. The entire process was supported by multidisciplinary protocols and web-based patient files. Methods The design of this study was quasi-experimental. In this study, 205 frail elderly patients of three general practitioner practices that implemented the integrated care model were compared with 212 frail elderly patients of five general practitioner practices that provided usual care. The outcomes were assessed using questionnaires. Baseline measures were compared with a three-month follow-up by chi-square tests, t-tests and regression analysis. Results and conclusion In the short term, the integrated care model had a significant effect on the attachment aspect of quality of life. The frail elderly patients were better able to obtain the love and friendship they desire. The use of care did not differ despite the preventive element and the need for assessments followed up with case management in the integrated care model. In the short term, there were no significant changes in health. As frailty is a progressive state, it is assumed that three months are too short to influence changes in health with integrated care models. A more longitudinal approach is required to study the value of integrated care on changes in health and the preservation of the positive effects on quality of life and health care use.
Descriptive epidemiology of Creutzfeldt‐Jakob disease in six european countries, 1993–1995

After the occurrence of bovine spongiform encephalopathy (BSE), there has been concern that transmission of BSE to the human population might result in a change in the epidemiological characteristics of Creutzfeldt‐Jakob disease (CJD). A collaborative study of CJD in the European Union was performed from 1993 to 1995, to compare data from national registries for CJD in France, Germany, Italy, The Netherlands, Slovakia, and the United Kingdom. Five hundred seventyfive patients with definite or probable CJD died in the study period with an overall annual morality rate of 0.71 cases per million. The incidence rates for CJD were similar in all participating countries despite variations in postmortem rates, and age‐specific incidence rates were also relatively consistent, with the exception of an increased incidence of CJD in patients younger than 39 years of age in the United Kingdom. In relation to etiological subtypes of CJD, 87% of cases were sporadic, 8% genetic, and 5% iatrogenic. Genetic forms of CJD comprised 80% of all cases in Slovakia, and iatrogenic forms of CJD occurred most frequently in France and the United Kingdom. The statistical data reported here do not provide evidence of a causal link between BSE and CJD in Europe as a whole. However, the study has established baseline epidemiological parameters for CJD in participating European countries, which may be important in the assessment of any future change in the characteristics of CJD as a result of the epidemic of BSE.
eview earning from experience : Event-related potential correlates of reward rocessing , neural adaptation , and behavioral choice atthew

To behave adaptively, we must learn from the consequences of our actions. Studies using event-related potentials (ERPs) have been informative with respect to the question of how such learning occurs. These studies have revealed a frontocentral negativity termed the feedback-related negativity (FRN) that appears after negative feedback. According to one prominent theory, the FRN tracks the difference between the values of actual and expected outcomes, or reward prediction errors. As such, the FRN provides a tool for studying reward valuation and decision making. We begin this review by examining the rror-related negativity (ERN) vent-related potentials (ERPs) emporal difference learning nterior cingulate cortex neural significance of the FRN. We then examine its functional significance. To understand the cognitive processes that occur when the FRN is generated, we explore variables that influence its appearance and amplitude. Specifically, we evaluate four hypotheses: (1) the FRN encodes a quantitative reward prediction error; (2) the FRN is evoked by outcomes and by stimuli that predict outcomes; (3) the FRN and behavior change with experience; and (4) the system that produces the FRN is maximally engaged by volitional actions. © 2012 Elsevier Ltd.

The suicidal process and self-esteem.

BACKGROUND It has not been made clear whether self-esteem is associated with the severity of suicidal behavior. AIMS To test the association between responses to a self-esteem inventory and levels of suicidal behavior as conceptualized in the notion of the suicide process. METHODS Questions on the severity of suicidal behavior over the lifespan (death wishes, ideation, plans, and attempts), as well as a self-esteem inventory, were administered to 227 university undergraduates. RESULTS A negative relationship was found between the level of suicidality and self-esteem. As hypothesized, there were fewer cases in each succeeding level of seriousness of suicidal behavior. However, nearly all cases from any particular level were contained in the cohort of individuals who had displayed suicidal behavior at a less serious level. CONCLUSIONS This suggests a possible progression through each of the stages of suicidal behavior, with very few cases showing a level of suicidal behavior that was not associated with a previous, less serious, form. It was hypothesized that early entry into the suicidal process may be indicated by low self-esteem, thus, allowing for a more timely preventive intervention.
Personality profiles among normal aged individuals as measured by the NEO-PI-R

Abstract The revised Neuroticism (N), Extraversion (E), Openness (O) to experience Personality Inventory (NEO-PI-R) is a multidimensional measure of normal personality traits that is intended to assess five major personality dimensions or domains—N, E, O, Agreeableness (A), and Conscientiousness (C). Although several studies have been conducted examining N; E, and O factors in people 65 through to 85 years old, there has been little research examining all five-core domains of personality in individuals 85 and older. We compared the NEO-PI-R domains and facet traits in the middle-aged/young-old versus old-old normal subjects. Thirty-eight community-dwelling subjects (22 women, 16 men) free from major neuropsychiatric disorders were given the NEO-PI-R, a self-administered 240-item personality inventory, assessing 30 facet traits within the five domains. We compared the scores of 21 middle-aged and young-old (age 50–84) individuals, to those of 17 old-old (age 85–100) subjects. The personality profiles of the two groups were similar except that the old-old group had lower scores on Extraversion, and four of the 30 facet traits (warmth, positive emotions, impulsiveness, and order) compared to the middle-aged/young-old group. These results were limited by the cross- sectional design and small sample size. Nonetheless, the findings suggest that the middle-aged/young-old and the old-old normal subjects have fairly similar personality traits.
First ranking of the scientific units Polish physical education higher schools based on monographs published in 2009-2012 indexed by the Polish Ministry of Science and Higher Education

Background In parallel with the scientific journals, the scholarly monographs are the key driver for the dissemination of scientific achievements. The aim of this article is to present the ranking of scientific units of Polish physical education higher schools based on the scholarly monographs published in 2009-2012. Material & Methods: Scholarly monographs and chapters in the monographs reported by 25 scientific units (faculties) of Polish physical education higher schools and related units in 2009-2012 were subjected to analysis. The Spearman’s rank correlation identifies the strength of correlation among publications and monographs, publications and chapters of the monographs, monographs and chapters in the monographs published by evaluated scientific units. Results: In the evaluated period (2009-2012) all units published 333 monographs, 222 (67%) of which were issued by academies of physical education and 111 (33%) were published by academics from the institutions of other types. In the same period 25 evaluated institutions published 3,139 chapters in monographs, 2,162 (69%) of which were issued by academies of physical education and 977 (31%) were published by academics from the institutions of other types. The analysis of rankings containing scientific units of Polish physical education higher schools evaluated for the monographs and chapters in monographs with ranking developed on the basis of scientific articles published in 2009-2012 in journals by computing the Spearman correlation revealed that the correlation between publications and monographs was 0.264, whereas between publications and chapters in monographs 0.207, indicating poor correlation in both cases. There was a significant correlation (0.658) between monographs and chapters in monographs, that evidences strong relationship. Conclusions: Monographs – regardless of other products of scientific activity – constitute a complementary bibliometric criterion measuring the productivity of authors, research groups, institutions and countries. Scientific achievements reported by institutions allowed to compare the scientific performance in the scientific units of Polish physical education higher schools on the unprecedented scale, measured both by the number of scholarly monographs and chapters in monographs, showing their potential, as well as the scientific activities directions and competitive capacity.
Luminosity- and Morphology-dependent Clustering of Galaxies

How does the clustering of galaxies depend on their inner properties like morphological type and luminosity? We address this question in the mathematical framework of marked point processes and clarify the notion of luminosity and morphological segregation. A number of test quantities such as conditional mark-weighted two-point correlation functions are introduced. These descriptors allow for a scale-dependent analysis of luminosity and morphology segregation. Moreover, they break the degeneracy between an inhomogeneous fractal point set and actual present luminosity segregation. Using the Southern Sky Redshift Survey 2, we find both luminosity and morphological segregation at a high level of significance, confirming claims by Benoist and colleagues in 1996 and Willmer and colleagues in 1998 using these data. Specifically, the average luminosity and the fluctuations in the luminosity of pairs of galaxies are enhanced out to separations of 15 h-1 Mpc. On scales smaller than 3 h-1 Mpc the luminosities on galaxy pairs show a tight correlation. A comparison with the random field model indicates that galaxy luminosities depend on the spatial distribution and galaxy-galaxy interactions. Early-type galaxies are also more strongly correlated, indicating morphological segregation. The galaxies in the PSCz catalog do not show significant luminosity segregation. This again illustrates that mainly early-type galaxies contribute to luminosity segregation. However, based on several independent investigations we show that the observed luminosity segregation cannot be explained by the morphology-density relation alone.
Partner discrepancies and age differences in marital quality: distinguishing the ideal, expected, and perceived partner.

OBJECTIVES Previous studies have observed a rebound of marital quality in later adulthood. This study tested whether partner discrepancy was a mediator of the age differences in marital quality. METHOD The present study assessed partner discrepancies and marital quality in 56 couples, 20-79 years old. Two levels of partner standards (ideal and expected standards) and 2 domains of partner characteristics (personality and support) were examined. RESULTS Husbands' partner discrepancies, but not wives', were found to mediate the curvilinear age differences in martial quality. DISCUSSION Consistent with the life-span theory of control, the results suggest that adjusting cognition about the partner is essential to the typically higher marital quality in later adulthood. The results also suggest that the level of comparison standards and the specific domain of partner characteristics should be considered in future studies.
A putative spermidine synthase interacts with flagellar switch protein FliM and regulates motility in Helicobacter pylori

The flagellar motor is an important virulence factor in infection by many bacterial pathogens. Motor function can be modulated by chemotactic proteins and recently appreciated proteins that are not part of the flagellar or chemotaxis systems. How these latter proteins affect flagellar activity is not fully understood. Here, we identified spermidine synthase SpeE as an interacting partner of switch protein FliM in Helicobacter pylori using pull‐down assay and mass spectrometry. To understand how SpeE contributes to flagellar motility, a speE‐null mutant was generated and its motility behavior was evaluated. We found that deletion of SpeE did not affect flagellar formation, but induced clockwise rotation bias. We further determined the crystal structure of the FliM‐SpeE complex at 2.7 Å resolution. SpeE dimer binds to FliM with micromolar binding affinity, and their interaction is mediated through the β1' and β2' region of FliM middle domain. The FliM‐SpeE binding interface partially overlaps with the FliM surface that interacts with FliG and is essential for proper flagellar rotational switching. By a combination of protein sequence conservation analysis and pull‐down assays using FliM and SpeE orthologues in E. coli, our data suggest that FliM‐SpeE association is unique to Helicobacter species.
Associations of Workplace Bullying and Harassment with Pain

The aim of this study was to investigate associations of workplace bullying and harassment with headache, stiffness of the neck or shoulders, lumbago, and pain of two or more joints. The subjects in this cross-sectional study were recruited from workers (n = 1,913) at 35 healthcare or welfare facilities in Japan. Because of non-participation or missing data, the number of subjects included in the analysis varied (response rate ≥ 77.1%). Workplace bullying and harassment were assessed using the Negative Acts Questionnaire. Depression was assessed using the Brief Job Stress Questionnaire. The frequency of pain experienced by workers in the previous month was evaluated using a four-point scale. Many of the associations of person-related bullying, work-related bullying, and sexual harassment with headache, stiffness of the neck or shoulders, lumbago, and pain of two or more joints were positive and significant (p < 0.05). Even after adjustment for depression, some of the associations remained significant (p < 0.05). For example, changes in the prevalence ratio for headache associated with a 1-point increase in the work-related bullying score were 1.05 (95% confidence interval (CI) 1.01 to 1.09) in men and 1.03 (95% CI 1.01 to 1.05) in women after adjustment for age, marital status, employment status, work shift, and depression.
Teachers’ self-initiated professional learning through Personal Learning Networks

It is widely acknowledged that to be able to teach language and literacy with digital technologies, teachers need to engage in relevant professional learning. Existing formal models of professional learning are often criticised for being ineffective. In contrast, informal and self-initiated forms of learning have been recently recognised as meaningful and relevant but little is known about these authentic learning experiences for professional purposes. This article investigates three teachers’ self-initiated professional learning about digital technologies through their Personal Learning Networks. The analysis identified that the participants’ everyday digital literacy practices provided opportunities for a range of professional practices that supported learning about digital technologies: information retrieval and resources aggregation, cooperation, collaboration, reflections and socialising. It also revealed that the teachers considered this form of learning as valuable. The article concludes by discussing how knowledge about self-initiated professional learning might be used to draw out some implications for teachers’ professional development.
Prospective Primary Teachers’ Perceptions About Their Ability to Use and Teach Thinking Skills

Cognitive acceleration programs have been successful in promoting reasoning skills in school students and in changing the pedagogy of the teachers implementing them. For this reason, this study explored if using such approach with a different population—prospective primary teachers—produced changes in relation to their perceptions about their ability to use and teach thinking. The results suggest that, from the participants’ points of view, the course helped them to improve not only their ability to think but also their awareness about their own thinking. However, a single cognitive acceleration in mathematics education (CAME) course was not sufficient to improve their confidence about teaching thinking.
Negative Emotional Content Disrupts the Coherence of Episodic Memories

Events are thought to be stored in episodic memory as coherent representations, in which the constituent elements are bound together so that a cue can trigger reexperience of all elements via pattern completion. Negative emotional content can strongly influence memory, but opposing theories predict strengthening or weakening of memory coherence. Across a series of experiments, participants imagined a number of person-location-object events with half of the events including a negative element (e.g., an injured person), and memory was tested across all within event associations. We show that the presence of a negative element reduces memory for associations between event elements, including between neutral elements encoded after a negative element. The presence of a negative element reduces the coherence with which a multimodal event is remembered. Our results, supported by a computational model, suggest that coherent retrieval from neutral events is supported by pattern completion, but that negative content weakens associative encoding which impairs this process. Our findings have important implications for understanding the way traumatic events are encoded and support therapeutic strategies aimed at restoring associations between negative content and its surrounding context.
An inflammatory link in atherosclerosis and obesity

Summary Atherosclerosis and obesity-induced metabolic dysfunction are lipid-driven inflammatory pathologies responsible for a major part of cardiovascular complications. Immune cell activation as well as interactions between the different immune cells is dependent on and controlled by a variety of co-stimulatory signals. These co-stimulatory signals can either aggravate or ameliorate the disease depending on the stage of the disease, the cell-types involved and the signal transduction cascades initiated. This review focuses on the diverse roles of the most established co-stimulatory molecules of the B7 and Tumor Necrosis Factor Receptor (TNFR) families, ie the CD28/CTLA4-CD80/CD86 and CD40L/CD40 dyads in the pathogenesis of atherosclerosis and obesity. In addition, we will explore their potential as therapeutic targets in both atherosclerosis and obesity.
Effect of dehulling of rapeseed on feed value and nutrient digestibility of rape products in pigs

In the presented study the influence of dehulling rapeseed on the composition of rapeseed meal (RM) and rapeseed cake (RC) and on its feed value for piglets and growing-finishing pigs was investigated. Before withdrawal of oil, rapeseed (variety Express) was dehulled applying a procedure developed by SKET GmbH Magdeburg and the Section Food-Technology of the University Essen. The steps of the dehulling procedure were described. For RM the oil was removed by the prepress-solvent procedure till a crude fat content of 2.1% in DM. RC was produced by pressing only resulting approximately 13% crude fat in DM. The RM and RC from not dehulled (ND) and dehulled (D) rapeseed were examined analytically. Crude nutrients, sugar and fibre substances, amino acids, some minerals and trace elements, fatty acids, glucosinolates and sinapine, and phytate were determined. By dehulling the seed the crude fibre content was decreased in RM and RC by approximately 40%. The ADF content declined by 35 and 39%, and the NDF content by 28% and 40% in RM and RC, respectively. The decrease in ADL content amounted to 50% and 65% for RM and RC, respectively. On the other hand, the CP content of RM and RC was increased by 7% and 13%, respectively, by dehulling the seed while the amino acid content of rape protein increased only slightly. The contents of glucosinolates and sinapine were also increased by dehulling, while the contents of phytate and phytate P were decreased. In digestibility and balance experiments with piglets and intact hybrid breeds of growing-finishing pigs, the digestibility of organic matter and of crude nutrients and the contents of digestible energy and metabolizable energy were estimated. Furthermore, the precaecal digestibility of crude nutrients and amino acids was determined with fistulated mini-pigs. By dehulling the seeds the digestibility of organic matter from RM and RC was improved in piglets and adult pigs by approximately 10%, and the ME contents increased by 13 – 15%. The precaecal digestibility of the sum of amino acids was increased by approximately 3 and 6 units in RM and RC, respectively. The precaecal digestibility of lysine in RM and RC reached that of soybean oil meal from not dehulled beans.
