A Low-Profile Omnidirectional Circularly Polarized Antenna Using Planar Sector-Shaped Endfire Elements

A single-layer circularly polarized (CP) antenna with omnidirectional radiation in the azimuth plane has been designed and evaluated. The concept is the combination of multiple identical endfire CP antenna elements in a circular array configuration. The design of each element is based on the superposition of two closely spaced complementary current sources, which are, respectively, realized by a sectorial parallel-plate cavity and arc-shaped strip arms. A meandered double-sided parallel strip line is introduced to adjust the phase relationship between two orthogonal linear polarized components. All antenna elements can be simultaneously excited by adopting a single coaxial probe in the center of the overall structure. Take 5.8-GHz Industrial Scientific Medical (ISM) band applications (5.725–5.875 GHz), for example, a prototype with a diameter of <inline-formula> <tex-math notation="LaTeX">$0.62\lambda _{0}$ </tex-math></inline-formula> and a low profile of <inline-formula> <tex-math notation="LaTeX">$0.029\lambda _{0}$ </tex-math></inline-formula> was fabricated. Experimental results show that the designed antenna has a usable bandwidth from 5.68 to 5.91 GHz (the common overlapped bandwidth limited by the −10 dB <inline-formula> <tex-math notation="LaTeX">$\vert S_{11}\vert $ </tex-math></inline-formula> and the 3-dB axial ratio). Within the operation band, good omnidirectivity and a wide coverage can be obtained.
Global Second Derivative Estimates for the Second Boundary Value Problem of the Prescribed Affine Mean Curvature and Abreu ’ s Equations

In this paper we prove the global second derivative estimates for the second boundary value problem of the prescribed affine mean curvature equation where the affine mean curvature is only assumed to be in L. Our result extends previous result by Trudinger and Wang in the case of globally bounded affine mean curvature and also covers Abreu’s equation.
The Temporal Evolution of Electromagnetic Markers Sensitive to the Capacity Limits of Visual Short-Term Memory

An electroencephalographic (EEG) marker of the limited contents of human visual short-term memory (VSTM) has previously been described. Termed contralateral delay activity, this consists of a sustained, posterior, negative potential that correlates with memory load and is greatest contralateral to the remembered hemifield. The current investigation replicates this finding and uses magnetoencephalography (MEG) to characterize its magnetic counterparts and their neural generators as they evolve throughout the memory delay. A parametric manipulation of memory load, within and beyond capacity limits, allows separation of signals that asymptote with behavioral VSTM performance from additional responses that contribute to a linear increase with set-size. Both EEG and MEG yielded bilateral signals that track the number of objects held in memory, and contralateral signals that are independent of memory load. In MEG, unlike EEG, the contralateral interaction between hemisphere and item load is much weaker, suggesting that bilateral and contralateral markers of memory load reflect distinct sources to which EEG and MEG are differentially sensitive. Nonetheless, source estimation allowed both the bilateral and the weaker contralateral capacity-limited responses to be localized, along with a load-independent contralateral signal. Sources of global and hemisphere-specific signals all localized to the posterior intraparietal sulcus during the early delay. However the bilateral load response peaked earlier and its generators shifted later in the delay. Therefore the hemifield-specific response may be more closely tied to memory maintenance while the global load response may be involved in initial processing of a limited number of attended objects, such as their individuation or consolidation into memory.
[Surveillance of influenza pandemic (H1N1)2009 in Spain].

BACKGROUND During the summer of 2009, Spain experienced the circulation of the novel influenza (H1N1)2009 virus, beyond the usual period of influenza activity, increasingly evolving up to the presentation in the early autumn of the first wave of the pandemic virus. The objectives of this study are to describe the evolution of the pandemic wave in our country and to assess their impact on morbidity and mortality of the Spanish population. METHOD From the information obtained from the Spanish Influenza Surveillance System and the Coordinating Centre for Health Alerts and Emergencies within Spanish Ministry of Health and Social Policy have been estimated a number of epidemiological and virological indicators that were used to assess the level of activity and intensity of the pandemic wave, as well as its severity RESULTS The beginning of the pandemic wave in Spain started in early autumn 2009 reaching the maximum weekly incidence rate of 372.15 cases/100,000 inhabitants. The highest incidence was registered in under 15 years old. Viral detection rate registered during the pandemic period remained at the range of previously recorded (46.4%). We estimated an overall mortality rate of 0.43 deaths per 1,000 pandemic cases. The 64% of deaths from pandemic influenza occurred in young adults and the highest mortality rates were registered in the 45-64 years age group with 9.35 deaths/1,000,000 inhabitants. Mortality associated with seasonal influenza in the period 2001-2008 was highest in those over 64 years (95% of all deaths). CONCLUSIONS The influenza (H1N1)2009 pandemic wave in Spain showed an early presentation and a medium level of influenza intensity compared to the previous thirteen seasonal influenza waves. Considering lethality or mortality rates, this first pandemic wave was also characterized by a mild severity, although a high percentage of deaths confirmed by the new virus were observed in population under 65 years.

The problems that were examined: (1) how the realization of speech act of refuser in French by the research subjects are used? (2) what strategies are used by research subjects in refuser to their partners? and (3) how the politeness levels are used in the Speech Act of refuser by Semester VI Students? Data obtained by â€œfishingâ€ techniques, â€œfishingâ€ the respondents using a questionnaire. The data were analyzed using equivalent analytical methods subtypes with a pragmatic â€œtool partners of the respondents" (the little brother, their lover, their rector, and their parking worker) and the power of mental sort (referential) owned by the researcher. The results showed that (1) of the realization of the speech act refuser, the respondents prefered the "declarative" mode to reject the partners than the other modes, both single mode and dual mode, (2) from the point of strategy used to "reject" partner respondents, most respondents tended to reject "indirectly" because it allows both participants involved in feel â€œface savingâ€, and (3) of the level politeness in the use of strategies, respondents tend to use the level politeness "very polite" and "polite" to others (lovers, rectors, and parking worker) and tend to "not polite" to the little brother/sister. Keywords: pragmatic, speech act, realization, strategy, levels of politeness
When Does Virtuality Really “Work”? Examining the Role of Work–Family and Virtuality in Social Loafing

We sought to clarify the relationship between virtuality and social loafing by exploring two work–family moderators—family responsibility and dissimilarity in terms of family responsibility—and two mediators—cohesion and psychological obligation—in two studies. We expected that “busy teams” (i.e., comprising similar individuals with many family responsibilities) would exhibit the strongest positive virtuality–social loafing relationship, and teams comprising similar individuals with few family responsibilities would experience a weaker virtuality–social loafing relationship. We expected that individuals working with dissimilar others would report consistently high levels of social loafing regardless of virtuality. Furthermore, we expected cohesion and psychological obligation to one’s teammates would mediate these effects. Similar individuals in teams indeed exhibited different virtuality–social loafing relationships in both studies, suggesting that the flexibility provided by virtuality might be more effective in teams comprising similar people with few family responsibilities. Study 2 further revealed that cohesion and obligation may mediate these effects, such that high levels of these mediators were associated with low levels of social loafing in similar teams comprising people with few family responsibilities. We discuss contributions to the virtual work and social loafing literatures, as well as the work–family and team literatures. We also suggest several specific actions managers can take on the basis of these findings, including for employees with few versus many family responsibilities.
Positive Parenting in Adolescence and Its Association with Future Hopes and Fears in Adulthood: A Longitudinal Analysis

During young adulthood (ages 20-39), individuals begin to develop a future orientation by thinking about their possible selves. In this longitudinal study, young adults’ future hopes and fears were examined in relation to their perceptions of the parenting style they experienced in adolescence. An interview was conducted with participants at age 26 and 32 to assess their future possible selves. Participants discussed both hoped-for and feared selves. The long-term impact of parenting on future hopes and fears was examined by exploring the possible impact of perceived parenting styles experienced in adolescence. Interviews were conducted in 2005 and 2011 with 26 year old participants (N = 100; 69% women) and 32 year old participants (N = 114; 71% women), respectively. At both ages, the top three hopes discussed by participants included work/career, marriage/relationship, and parenthood. At age 26, the top three fears discussed by participants included marriage/relationship, work/career, and mental health, however, at age 32, participants identified physical health and parenthood in addition to marriage/relationship fears. Perceived parenting style at adolescence did not generally have any association with hopes and fears at ages 26 and 32. However, participants who scored higher on the perceived parenting measure at age 17 discussed more parenthood hopes at age 32 compared to the participants who reported lower perceptions of the parenting styles they experienced. The results of the current study show how young adults are defining their future, with frequent consideration of work/career, marriage/relationships, and parenthood. These findings may inform the design of career interventions and therapy setting for young adults.
Coulomb trajectory effects on electron-impact detachment of negative ions and on mutual neutralization cross sections

Cross sections of electron-impact detachment of negative ions and of mutual neutralization between positive and negative ions are calculated using a model based on the semiclassical theory for ion - atom collisions but modified to include Coulomb trajectory effects. It is shown that the method allows us to obtain accurate results for collisions down to low energies. The Coulomb repulsion between the electron and the negative ion accounts for the rapid decrease of detachment cross sections at low energies, and the Coulomb attraction between positive and negative ions accounts for the rapid increase of neutralization cross sections at low velocities.
Realistic Belief Revision

In this paper we consider the implications for belief revision of weakening the logic under which belief sets are taken to be closed. A widely held view is that the usual belief revision functions are highly classical, especially in being driven by consistency. We show that, on the contrary, the standard representation theorems still hold for paraconsistent belief revision. Then we give conditions under which consistency is preserved by revisions, and we show that this modelling allows for the gradual revision of inconsistency.
A Multilevel Approach to Social Capital

The concept of social capital serves as a structural hole in the landscape of scholarly disciplines in social science. This article argues that the unifying strength of the concept is based mainly upon the semantics of trust and networks and is, therefore, superficial, and that various levels of analysis may yield fundamental differences in its applications. Micro and macro levels are used to analyze the concepts of trust and networks, and their measurement, and the acquired insights are used to offer avenues for future multilevel research of social capital.
The role of upper torso and pelvis rotation in driving performance during the golf swing

Abstract While the role of the upper torso and pelvis in driving performance is anecdotally appreciated by golf instructors, their actual biomechanical role is unclear. The aims of this study were to describe upper torso and pelvis rotation and velocity during the golf swing and determine their role in ball velocity. One hundred recreational golfers underwent a biomechanical golf swing analysis using their own driver. Upper torso and pelvic rotation and velocity, and torso-pelvic separation and velocity, were measured for each swing. Ball velocity was assessed with a golf launch monitor. Group differences (groups based on ball velocity) and moderate relationships (r ≥ 0.50; P < 0.001) were observed between an increase in ball velocity and the following variables: increased torso – pelvic separation at the top of the swing, maximum torso – pelvic separation, maximum upper torso rotation velocity, upper torso rotational velocity at lead arm parallel and last 40 ms before impact, maximum torso – pelvic separation velocity and torso – pelvic separation velocity at both lead arm parallel and at the last 40 ms before impact. Torso – pelvic separation contributes to greater upper torso rotation velocity and torso – pelvic separation velocity during the downswing, ultimately contributing to greater ball velocity. Golf instructors can consider increasing ball velocity by maximizing separation between the upper torso and pelvis at the top of and initiation of the downswing.
A Case Study of the Social Needs of Danisha: An Underachieving Gifted African-American Female.

Historically, African‐American students have experienced significant levels of underachievement. Similarly, many gifted females fail to reach their potential. Despite numerous studies on underachievement among African‐American students and among gifted females, few studies have addressed underachievement among gifted African‐American females. In the present case study, the authors address this shortcoming. They explore the topic of underachievement among gifted African‐American females by exploring their perceptions of social variables and understanding their needs. Specifically, through the lens of social variables (e.g., peer, teachers, curricular issues) the authors explore the perceptions of a 15 year‐old gifted, underachieving African‐American female 9th grader, and make recommendations to improve her educational experiences and those of other gifted African‐American females.

Discourse, Interests and Subjects: ‘Interests’ in Political Analysis

This paper argues that interests have consequences in so far as they provide actors with reasons for action, and that actors may find reasons for action in interests they ascribe to themselves and in interests they ascribe to others. This argument undermines many of the ways in which concepts of interests have traditionally been used in social and political analysis. Section I is an introductory discussion of the uses of concepts of interests in political analysis. Section II discusses the place of interests in the explanation of action and Section III discusses connections between interests and actors' social location. A brief conclusion summarises the main arguments of the two central sections.
Honeycomb Networks: Topological Properties and Communication Algorithms

The honeycomb mesh, based on hexagonal plane tessellation, is considered as a multiprocessor interconnection network. A honeycomb mesh network with n nodes has degree 3 and diameter /spl ap/1.63/spl radic/n-1, which is 25 percent smaller degree and 18.5 percent smaller diameter than the mesh-connected computer with approximately the same number of nodes. Vertex and edge symmetric honeycomb torus network is obtained by adding wraparound edges to the honeycomb mesh. The network cost, defined as the product of degree and diameter, is better for honeycomb networks than for the two other families based on square (mesh-connected computers and tori) and triangular (hexagonal meshes and tori) tessellations. A convenient addressing scheme for nodes is introduced which provides simple computation of shortest paths and the diameter. Simple and optimal (in the number of required communication steps) routing, broadcasting, and semigroup computation algorithms are developed. The average distance in honeycomb torus with n nodes is proved to be approximately 0.54/spl radic/n. In addition to honeycomb meshes bounded by a regular hexagon, we consider also honeycomb networks with rhombus and rectangle as the bounding polygons.
On Product Uncertainty in Online Markets: Theory and Evidence

Online markets pose a difficulty for evaluating products, particularly experience goods, such as used cars, that cannot be easily described online. This exacerbates product uncertainty, the buyer's difficulty in evaluating product characteristics, and predicting how a product will perform in the future. However, the IS literature has focused on seller uncertainty and ignored product uncertainty. To address this void, this study conceptualizes product uncertainty and examines its effects and antecedents in online markets for used cars (eBay Motors). Extending the information asymmetry literature from the seller to the product, we first theorize the nature and dimensions (description and performance) of product uncertainty. Second, we propose product uncertainty to be distinct from, yet shaped by, seller uncertainty. Third, we conjecture product uncertainty to negatively affect price premiums in online markets beyond seller uncertainty. Fourth, based on the information signaling literature, we describe how information signals (diagnostic product descriptions and third-party product assurances) reduce product uncertainty. The structural model is validated by a unique dataset comprised of secondary transaction data from used cars on eBay Motors matched with primary data from 331 buyers who bid on these used cars. The results distinguish between product and seller uncertainty, show that product uncertainty has a stronger effect on price premiums than seller uncertainty, and identify the most influential information signals that reduce product uncertainty. The study's implications for the emerging role of product uncertainty in online markets are discussed.
Demographics, Causality, Work Salience, and the Career Maturity of African-American Students: A Causal Model.

Abstract This study examined a causal model of career maturity based on Super's theory (1953, 1990) and determined its fit to a sample of African-American male and female university students. Using structural equation modeling with data from 288 African-American students (freshman to doctoral levels), the results confirmed that attributions of causality and work salience moderate the effects of sex, SES, and educational level on career maturity. Work salience exerted the strongest direct effect on career maturity, while level of education had the strongest indirect effect. African-American students appeared to express more salience for home and family roles as compared to work or study roles.
Docosahexaenoic Acid and Adult Memory: A Systematic Review and Meta-Analysis

Introduction Subjective memory complaints are common with aging. Docosahexaenoic acid (DHA; 22:6 n-3) is a long-chain polyunsaturated fatty acid (LCPUFA) and an integral part of neural membrane phospholipids that impacts brain structure and function. Past research demonstrates a positive association between DHA plasma status/dietary intake and cognitive function. Objectives The current meta-analysis was designed to determine the effect of DHA intake, alone or combined with eicosapentaenoic acid (EPA; 20:5 n-3), on specific memory domains: episodic, working, and semantic in healthy adults aged 18 years and older. A secondary objective was to systematically review/summarize the related observational epidemiologic literature. Methods A systematic literature search of clinical trials and observational studies that examined the relationship between n-3 LCPUFA on memory outcomes in healthy adults was conducted in Ovid MEDLINE and EMBASE databases. Studies of subjects free of neurologic disease at baseline, with or without mild memory complaints (MMC), were included. Random effects meta-analyses were conducted to generate weighted group mean differences, standardized weighted group mean differences (Hedge’s g), z-scores, and p-values for heterogeneity comparing DHA/EPA to a placebo. A priori sub-group analyses were conducted to evaluate the effect of age at enrollment, dose level, and memory type tested. Results Episodic memory outcomes of adults with MMC were significantly (P<.004) improved with DHA/EPA supplementation. Regardless of cognitive status at baseline, > 1 g/day DHA/EPA improved episodic memory (P<.04). Semantic and working memory changes from baseline were significant with DHA but no between group differences were detected. Observational studies support a beneficial association between intake/blood levels of DHA/EPA and memory function in older adults. Conclusion DHA, alone or combined with EPA, contributes to improved memory function in older adults with mild memory complaints.
