Regarding the design of the antennas, it is considered the Substrate Dielectric (FR4) with permittivity of 4.7, loss tangent of 0.019 and substrate's height of 1.6 mm. The results were obtained by Computer Simulation Technology (CST) software in terms of return loss, gain, Voltage Standing Wave Ratio (VSWR) and, radiation pattern.
Is a Federal Europe Possible

I have been active in Spanish and European politics for over 30 years. Back in 1998-1999, when I was the nominee of the Spanish Worker’s Socialist Party for prime minister, I said that I was in favor of a Federal Spain in a Federal Europe. Well, it did not go down too well among some Party insiders, including former prime minister Felipe Gonzalez, who told me that federalism was disliked in both the European Union (EU) and Spain. He may have been right at the time.
Evaluating interactive videoconferencing for assessing symptoms of autism.

BACKGROUND Autism affects as many as 1 in 88 children. Best practices recommend early identification and intervention for optimal outcomes. Currently, a gap exists between time of first concern and diagnosis, particularly for families living in rural areas. Telemedicine as a tool for assessment and diagnosis of autism is one way to address this disparity. Emerging evidence suggests telemedicine as a viable option for assessing children with a variety of special needs. MATERIALS AND METHODS This study expands upon the current literature by investigating clinicians' ability to assess autism via telemedicine. Using interactive videoconferencing, we simulated autism assessment procedures with families with an existing diagnosis (autism or developmental disability) using current gold-standard assessment tools. We compared diagnostic accuracy, item-by-item reliability on the Autism Diagnostic Observation Schedule (ADOS)-Module 1, and the Autism Diagnostic Interview-Revised (ADI-R) as well as parent satisfaction in an in-person and interactive videoconferencing condition. Ten children (3-5 years old) with developmental delays and 11 children matched on chronological age with a diagnosis of autism were assigned to be assessed and interviewed either in-person or over videoconferencing. Clinicians observed both in-person and through videoconferencing regardless of patient assignment. RESULTS Results indicated no significant difference in reliability of diagnostic accuracy, ADOS observations, ratings for ADI-R parent report of symptoms, and parent satisfaction between conditions. Results indicate adequate clinician agreement and parent satisfaction regardless of observational condition. CONCLUSIONS Future research should include a larger sample size and assess children without an existing diagnosis.
An Approach to Detecting Text Autorship in the Spanish Language

Authors tend to express themselves using language in ways that reflect particular styles, vocabularies, biases, idioms, etc. These features can be captured in the so-called firm or stylone. Although capturing these attributes with high fidelity has proven to be very challenging, some advances have been made. Stylometry is the analysis of the unique attributes that are expressed by an author unconsciously through his or her publications. In this paper we investigate techniques for the detection of authorship patterns from the text content of a large number of digital documents, including e-mails, academic notes and free redaction in the Spanish language. A mechanism based on pondering parameters, including statistical observations, extracting a pattern is proposed. We defined 150 stylistic criteria parameters adapted to the Spanish language to compute our metric. Extensive experiment results are also presented.
Weaknesses and Reform of Australia's Renewable Electricity Support

Australia has high per capita greenhouse gas emissions, low utilization of renewable electricity and abundant renewable electricity resources. This article discusses and analyses the significance of electricity generation emissions in Australia's overall greenhouse performance, its renewable electricity generation record, the flaws in the country's Renewable Portfolio Standard and the political forces that have shaped these features. The possible changes to Australia's renewable electricity target to enable it to achieve major greenhouse gas emission reduction and the political forces that influence Australia's renewable electricity policy are examined.
China's Changing Political Landscape: Prospects for Democracy

While China's economic rise is being watched closely around the world, the country's changing political landscape is intriguing, as well. Forces unleashed by market reforms are profoundly recasting state-society relations. Will the Middle Kingdom transition rapidly, slowly, or not at all to political democracy? In China's Changing Political Landscape , leading experts examine the prospects for democracy in the world's most populous nation. China's political transformation is unlikely to follow a linear path. Possible scenarios include development of democracy as we understand it; democracy with more clearly Chinese characteristics; mounting regime instability due to political and socioeconomic crises; and a modified authoritarianism, perhaps modeled on other Asian examples such as Singapore. Which road China ultimately takes will depend on the interplay of socioeconomic forces, institutional developments, leadership succession, and demographic trends. Cheng Li and his colleagues break down a number of issues in Chinese domestic politics, including changing leadership dynamics; the rise of business elites; increased demand for the rule of law; and shifting civil-military relations. Although the contributors clash on many issues, they do agree on one thing: the political trajectory of this economic powerhouse will have profound implications, not only for 1.3 billion Chinese people, but also for the world as a whole.
The Frequency of Summands of a Particular Size in Palindromic Compositions

A composition of a positive integer n consists of an ordered sequence of positive integers whose sum is n. A palindromic composition is one for which the sequence is the same from left to right as from right to left. This paper shows various ways of generating all palindromic compositions, counts the number of times each integer appears as a summand among all the palindromic compositions of n, and describes several patterns among the numbers generated in the process of enumeration.
Centralization or Decentralization of Decision Rights? Impact on IT Performance of Firms

The effects of IT on the decision making structure of firms has been a topic of debate for decades. On the one hand, IT increases the information available to top management, and the coordination advantages that it provides may lead firms to centralize decision making. On the other hand, IT makes it possible to disseminate global information of the firm to line workers enabling them to make better decisions as well as enhances management's monitoring capability, favoring decentralization. In order to understand the economy wide effects of centralization and decentralization of decision rights on the productivity effect of IT, we conduct an empirical analysis to examine the change in the effects of IT performance in firms that changed its decision making structure, using a panel data set for 2,300 Japanese firms over 4 years. Our results indicate that both centralization and decentralization have a substantial productivity effect on IT for firms that changed its decision making structure and the productivity effects are more marked for firms that conducted radical change of decision rights. Moreover, we find evidence that changes in decision rights have a more pronounced productivity effect on large firms. Finally, our results show that productivity effects due to changes in decision rights are realized only in the non-manufacturing sectors. This paper sheds some light on the effects of decision rights on firms' IT performance and underscores the importance of organizational redesign accompanying IT investment.
Internet IPO Auctions : Will they eliminate traditional underwriting inefficiencies ?

Initial Public Offerings (IPOs) in the United States have been mainly underwritten and sold using the bookbuilding method; a method inherently riddled with inefficiencies and information asymmetries. Consequently, IPOs in the U.S. (and other countries for that matter) have been persistently underpriced, at the expense of both the issuing firm and public investors. Alternative underwriting procedures, such as auctioning methods, have been proposed in various countries and have resulted in better pricing. The dominant auctioning method used for underwriting has been the sealed-bid uniform price/market-clearing auction1, where the share price is the lowest price at which supply (the number of shares issued) equals demand. This leads us to the question of whether the sealed-bid uniform-price auction is indeed the most efficient auction structure for the sale of IPOs, and more specifically for the sale of IPOs underwritten over the Internet. We define an efficient auction as one whose pricing mechanism generates a price that is closest to the "market" price. Thus in an IPO auction shares priced in an efficient auction would show a smooth transition onto the market and there would be no abnormal returns on the first trading day. Drawing on auction theory and simulation results, this paper shows that the uniform-price auction is indeed the most efficient auction for the sale of IPOs. We develop our reasoning by analyzing two main auctioning 1 Note that financial practitioners refer to it as a Dutch auction, while economists call it an English auction. Thus for this paper we will refer to it simply as a uniform -price auction.
Reasons given by older people for limitation or avoidance of driving.

PURPOSE To understand the driving behavior of older adults, this study examines self-reported reasons for driving limitation or avoidance. DESIGN AND METHODS Baseline interviews were conducted (n = 2,046) as part of a community-based study of aging and physical performance in persons aged 55 years or older in Sonoma, California. Twenty-one medical and nonmedical reasons for limiting or avoiding driving were examined by age and gender. RESULTS Most older people continue to drive; however, many, especially older women, report one or more reasons to limit or avoid driving. Among medical reasons, problems with eyesight are by far the most often cited; no other health problem was identified as a major reason for limitation. Among nonmedical reasons, being concerned about an accident, being concerned about crime, and having no reason to drive were often cited. Important predictors of reported driving limitations were low income, limited functional status, and self-report of poor vision. IMPLICATIONS Understanding factors that affect driving patterns in older adults, including medical and nonmedical reasons, will assist in developing both enhancements to extend safe driving years and responses to the consequences of driving reduction.
Near-Infrared Properties of Type Ia Supernovae

Abstract The photometric properties of Type Ia supernovae (SNe Ia) in the near-infrared as garnered from observations made over the last 30 years are reviewed. During this period, light curves for more than 120 nearby SNe Ia have been published, revealing considerable homogeneity but also some fascinating differences. These data have confirmed that, for all but the fastest declining objects, SNe Ia are essentially perfect standard candles in the near-infrared, displaying only a slight dependence of peak luminosity on decline rate and color.

Delay Variation Analysis in Consideration of Dynamic Power Supply Noise Waveform

Delay variability due to dynamic power supply noise is elucidated by on-chip signal waveform measurements at 100-ps/100-muV resolutions applied to a 180-nm CMOS digital circuit. A single-tone noise model represents a dynamic power supply noise waveform with the most significant frequency component and leads to circuit-level simulation that can efficiently capture the effects of switching signal waveform modulation on delay in a logic gate. Simulation and measurements show excellent agreement in delay variation, even with relative differences among clock domains in timing as well as in noise strength. The proposed delay simulation technique actualizes the delay analysis in consideration of dynamic power supply noise and thus consolidates the timing closure especially in a high speed digital design
Incentive Design to Enhance the Reach of Weight Loss Program

This study employed stated-preference methods to elicit individuals’ program participation preference towards different financial incentive attributes. The results of this study show promise for the use of carefully designed incentive programs to raise participation in weight loss programs. Results show that a fungible payment form is important for the incentive to be effective in reach (i.e., cash and grocery gift-cards are preferred over gym passes and waivers of insurance co-payments). Furthermore, immediate payment is preferred over delayed payment.
Cloning, characterization and evolution of the BsuFI restriction endonuclease gene of Bacillus subtilis and purification of the enzyme.

The restriction endonuclease (R.BsuFI) of Bacillus subtilis recognizes the target DNA sequence 5' CCGG. The R.BsuFI gene was found in close proximity to the cognate M.BsuFI gene, which had previously been characterized (1). Cloning of the R.BsuFI gene in E.coli was only possible with the M.BsuFI Mtase gene present on a compatible plasmid. The cloned R.BsuFI gene was expressed in E. coli and restriction activity was observed in vivo and in vitro. The R.BsuFI gene consists of 1185 bp, coding for a protein of 395 amino acids with a calculated molecular weight of 45.6 kD. The R.BsuFI enzyme was purified to homogeneity following overexpression. It presumably works as a dimer and cleaves the 5' CCGG target sequence between the two cytosines to produce sticky ends with 5' CG overhangs, like the isoschizomers R.MspI and R.HpaII. The relatedness between R.BsuFI and R.MspI is reflected by significant similarities of the amino acid sequences of both enzymes. This is the first case where such similarities have been observed between isoschizomeric restriction endonucleases which belong to 5mC specific R/M systems. This observation suggests that R.BsuFI and R.MspI genes derive from a common ancestor. In spite of such functional and evolutionary relatedness, the R/M systems differ in the arrangement of their R and M genes. In the BsuFI system transcription of the two genes is convergent, whereas divergent transcription occurs in the MspI system.
The criterion-related validity of personality measures for predicting GPA: a meta-analytic validity competition.

Interest in the role of personality traits in predicting academic performance outcomes has steadily increased over the last several decades, enough to produce a number of meta-analyses that summarize this research (e.g., Poropat, 2009; Richardson, Abraham, & Bond, 2012). These previous meta-analyses combine a variety of alternative personality measures under the assumption that they all reflect the same personality traits and thus predict outcomes similarly. The current meta-analysis tests this assumption by comparing different personality measures when predicting postsecondary grade point average (GPA). The operational validities (r+) of 5 frequently used measures of the Big Five personality traits were compared: the NEO Personality Inventory--Revised (NEO-PI-R; Costa & McCrae, 1992), the NEO Five-Factor Inventory (NEO-FFI; Costa & McCrae, 1992), the Big Five Inventory (BFI; e.g., Benet-Martínez & John, 1998), Goldberg's (1992) unipolar Big Five Factor Markers (Markers), and the Big Five International Personality Item Pool (IPIP; Goldberg, 1999). A systematic review of the psychological literature from 1992 to 2012 was conducted, identifying 51 studies containing 274 correlations. Conscientiousness demonstrated the strongest criterion-related validity for predicting GPA (r+ = .23), consistent with previous meta-analyses; in addition, this overall validity was found to be robust across measures (r(BFI)(+) = . 24, r(IPIP)(+) = . 21, r(Markers)(+) = . 15, r(NEO-FFI)(+) = . 24, r(NEO-PI-R)(+) = . 26). Although the criterion-related validities for Extraversion, Agreeableness, Neuroticism, and Openness to Experience (Intellect) differed by measure, they were generally low (r+s < .10). Practical implications of the findings and directions for future research are discussed.
Collecting a Why-Question Corpus for Development and Evaluation of an Automatic QA-System

Question answering research has only recently started to spread from short factoid questions to more complex ones. One significant challenge is the evaluation: manual evaluation is a difficult, time-consuming process and not applicable within efficient development of systems. Automatic evaluation requires a corpus of questions and answers, a definition of what is a correct answer, and a way to compare the correct answers to automatic answers produced by a system. For this purpose we present a Wikipedia-based corpus of Whyquestions and corresponding answers and articles. The corpus was built by a novel method: paid participants were contacted through a Web-interface, a procedure which allowed dynamic, fast and inexpensive development of data collection methods. Each question in the corpus has several corresponding, partly overlapping answers, which is an asset when estimating the correctness of answers. In addition, the corpus contains information related to the corpus collection process. We believe this additional information can be used to post-process the data, and to develop an automatic approval system for further data collection projects conducted in a similar manner.
The Set2 Histone Methyltransferase Functions through the Phosphorylated Carboxyl-terminal Domain of RNA Polymerase II*

The histone methyltransferase Set2, which specifically methylates lysine 36 of histone H3, has been shown to repress transcription upon tethering to a heterologous promoter. However, the mechanism of targeting and the consequence of Set2-dependent methylation have yet to be demonstrated. We sought to identify the protein components associated with Set2 to gain some insights into the in vivo function of this protein. Mass spectrometry analysis of the Set2 complex, purified using a tandem affinity method, revealed that RNA polymerase II (pol II) is associated with Set2. Immunoblotting and immunoprecipitation using antibodies against subunits of pol II confirmed that the phosphorylated form of pol II is indeed an integral part of the Set2 complex. Gst-Set2 preferentially binds to CTD synthetic peptides phosphorylated at serine 2, and to a lesser extent, serine 5 phosphorylated peptides, but has no affinity for unphosphorylated CTD, suggesting that Set2 associates with the elongating form of the pol II. Furthermore, we show thatset2Δ ppr2Δ double mutants (PPR2 encodes TFIIS, a transcription elongation factor) are synthetically hypersensitive to 6-azauracil, and that deletions in the CTD reduce in vivo levels of H3 lysine 36 methylation. Collectively, these results suggest that Set2 is involved in regulating transcription elongation through its direct contact with pol II.
Impulse-86: a substrate for object-oriented interface design

Impulse-86 provides a general and extensible substrate upon which to construct a wide variety of interactive user interfaces for developing, maintaining, and using knowledge-based systems. The system is based on five major building blocks: Editor, Editor Window, PropertyDisplay, Menu, and Operations. These building blocks are interconnected via a uniform framework and each has a well-defined set of responsibilities in an interface. Customized interfaces can be designed by declaratively replacing some of the building blocks in existing Impulse-86 templates. Customization may involve a wide range of activities, ranging from simple override of default values or methods that control primitive operations (e.g., font selection), to override of more central Impulse-86 methods (e.g., template instantiation). Most customized interfaces require some code to be written—to handle domain-specific commands. However, in all cases, the Impulse-86 substrate provides considerable leverage by taking care of the low-level details of screen, mouse, and keyboard manipulation. Impulse-86 is implemented in Strobe, a language that provides object-oriented programming support for Lisp. This simplifies customization and extension.
Exploiting Time-Frequency Coherence to Achieve Coherent Capacity in Wideband Wireless Channels

It was widely believed that knowledge of channel state information (CSI) at the receiver imposes a sharp cut-off on the achievability of coherent capacity at large bandwidths (or low SNRs). Recent works have shown that by either employing an explicit training-based scheme or an implicit channel-learning and communication scheme, rates intermediate between the coherent and the non-coherent extremes can be achieved. However, to bridge the gap between these two extremes, these works assume that the coherence time of the channel increases as the signaling bandwidth increases, without providing any physical basis that could lead to such a scaling relationship. In this paper, we study the wideband capacity of doubly dispersive underspread wireless channels employing explicit training and communication using short-time Fourier (STF) basis functions, that serve as approximate eigen-functions for such channels. Requirements on coherence time in existing works are naturally replaced with requirements on the time-frequency coherence dimension in STF signaling. Motivated by recent measurement campaigns, we propose a sparse multipath channel model in which the coherence dimension naturally scales with signal-space dimensions. Sparsity in the delay-Doppler domain affords two important benefits that have not been recognized thus far: 1) The coherence time requirement necessary to achieve an operational coherence level is dramatically reduced by exploiting sparsity in the delay domain, and 2) Sparsity in the Doppler domain can be used to achieve any operational level of coherence by appropriately scaling the signaling duration as a function of signaling bandwidth.
