“Making space” in practice and education: research support services in academic libraries

Purpose – How academic libraries support the research of their parent institutions has changed as a result of forces such as changing scholarly communication practices, technological developments, reduced purchasing power and changes in academic culture. The purpose of this paper is to examine the professional and educational implications of current and emerging research support environments for academic libraries, particularly with regard to research data management and bibliometrics and discuss how do professionals and educators “make space” as new service demands arise? Design/methodology/approach – The present paper uses data from a recent survey of research support provision by academic libraries in Australia, New Zealand, the UK and Ireland, (authors 2013), and provides additional in depth analysis of the textual responses to extend the analysis in the light of forces for change in higher education. The original online questionnaire surveyed current and planned research support in academic libraries.
Open source software movement in the French central and local government: a retrospective and prospective exploratory study

As one of Europe's leaders in modernising government through the use of Information and Communication Technologies (ICTs), France offers an opportunity to investigate how the use of Open Source software contributes to the process of improving government performance. This paper examines the extent to which the French government accepts Open Source solutions as part of its use of ICT to support e-democracy through government operations. This study bases its investigation on interviews of more than 100 program and ICT officials responsible for running or supporting government programs in France.
An New Image Feature Based on ROLD

To make robot more intelligence, this paper proposed a new image feature named as ROLD-map which based on Rank-Ordered Logarithmic Difference (ROLD), and this feature enable researchers understand images complication directly and accuracy. Experimental data show that it can recognize the sky, tree and road obviously with very little time through proposed feature. It provides the fundamental analysis for improving the precision of image recognition, and also gives the reference research for improving the precision of image recognition for the process of visual navigation of robot.
Quality evaluation of pansharpened hyperspectral images generated using multispectral images

Hyperspectral remote sensing can provide a smooth spectral curve of a target by using a set of higher spectral resolution detectors. The spatial resolution of the hyperspectral images, however, is generally much lower than that of multispectral images due to the lower energy of incident radiation. Pansharpening is an image-fusion technique that generates higher spatial resolution multispectral images by combining lower resolution multispectral images with higher resolution panchromatic images. In this study, higher resolution hyperspectral images were generated by pansharpening of simulated lower hyperspectral and higher multispectral data. Spectral and spatial qualities of pansharpened images, then, were accessed in relation to the spectral bands of multispectral images. Airborne hyperspectral data of AVIRIS was used in this study, and it was pansharpened using six methods. Quantitative evaluations of pansharpened image are achieved using two frequently used indices, ERGAS, and the Q index.
Performance and Optimization of Switched Diversity Systems for the Detection of Signals with Rayleigh Fading

The performance and optimization of switched diversity systems are considered. First, the one-dimensional distribution and probability density functions of the envelope of the received signal are obtained for three different switching strategies. This information is used to obtain the average probability of bit error for the case of non-coherent detection of binary FSK signals with Rayleigh fading envelopes and additive white Gaussian noise. The optimization of two of these switching strategies is then considered, and it is shown that by proper selection of switching thresholds, the average probability of bit error during detection can be minimized. It is also shown that these optimized switching strategies yield a significant improvement in performance over non-diversity systems and can approach the performance of more complex receivers such as maximal ratio combining. Computer simulations of switched diversity systems using a practical field model are used to verify the analysis.
Study of Dynamic Polling in the IEEE 802.11 PCF

Point Coordination Function (PCF) of the IEEE 802.11 protocol providing a centrally-controlled polling-based multiple access to a wireless channel is very efficient in high load conditions. However, its performance degrades with increasing the number of terminals and decreasing the load, because of wastes related to unsuccessful polling attempts. To solve the problem, we propose and study analytically the generic dynamic polling policy using backoff concept. For this aim, we develop Markov models describing the network queues changes, what allows us to estimate such performance measures as the average MAC service time and the average MAC sojourn time, to show the dynamic polling efficiency and to tune optimally the backoff rule.
Multi-signal time-frequency model fitting using an approximate maximum likelihood algorithm

By taking advantage of the moderate computational demand of the recently developed approximate maximum likelihood (AML) algorithms, it is shown that with algorithm refinement linear parametric model-fitting can be extended to a wide range of complex data interpretation tasks, including time-frequency and time-scale analyses. A novel version of the IMP (incremental multiparameter) AML algorithm (using a partially deterministic and partially stochastic signal model) is suggested for adaptive detection, tracking and extraction from time-series waveforms of several modulated signal components of differing bandwidths. <<ETX>>
Semantic Anomalies in Second Language Processing: An Electrophysiological Study

How humans` language processing occurs in the brain in real-time has been one of the major issues to clarify in the field. Especially, it is interesting to see related to the issue how bilinguals do in their second language (L2) processing as compared to monolinguals of the language. This study conducts an event-related potential (ERP) study to investigate the temporal neural dynamics of semantic processing in bilinguals. The experiment was done with Korean speakers of English as an L2, divided into two groups depending on their L2 proficiency level. The typical semantic anomaly paradigm was adopted for the material; semantically anomalous sentences end with a word which is not congruent in the sentence context. It was investigated if semantically anomalous stimuli elicit N400, known as meaning-related ERP component since Kutas & Hillyard (1980). Overall, similar pattern of the N400 effect was observed in the high proficiency group, while no significant effect was found in the low proficiency group. Though the results do not show a complete match in every detail, the study suggests that the bilinguals` semantic processing resembles monolinguals` semantic processing to a significant extent. This study also suggests that proficiency has a close correlation with brain responses in semantic processing in L2. (Gyeongsang National University)
Applying translation theory in teaching

Abstract Institutional teaching of Translation Studies has evolved in the past decades. I believe this growth is in part due to the connection between theory and teaching practice. The present article focusses on how seven proponents of various translation theories teach in classrooms, on why theory is important for the teaching of the profession, and on the nature of theory. This discussion leads to a fundamental concern for the traing future translators for professional work: “On what basis could the selection, grading and presentation of materials for the training of translators be made more effective? ” (Hatim and Mason 1997: 179) It is argued that translation trainees should be exposed on a variety of approaches to translation which are inspired by and connect to different theoretical schools so that students are in this way taught to be flexible in their approach to texts and will also learn theory in practical application.
Gender factor in crop farmers’ access to agricultural information in rural areas of Delta State, Nigeria

Focuses on crop farmers’ access to agricultural information in rural areas of Delta State, Nigeria. Data were gathered by questionnaire from ten villages. Farmers of both genders experienced obstacles to information use, although findings revealed that there were also differences between male and female crop farmers with respect to their information needs and sources of agricultural information. Female crop farmers experienced greater problems in accessing agricultural information. However, the major information problems suffered by farmers are not gender‐specific problems. Concludes with recommendations to enhance all crop farmers’ access to agricultural information.
Literacy Instruction in 10 Fourth-Grade Classrooms in Upstate New York

Literacy instruction was observed in 6 fourth-grade and 4 fifth-grade classrooms over the course of 1 year. Using the method of constant comparison, commonalities among classrooms were identified in the areas of reading instruction, writing instruction, instructional materials, instructional goals, management, and classroom motivational orientation. Teachers in all classrooms provided a combination of authentic reading and writing experiences and explicit skills instruction. Dimensions of difference among classrooms were also identified with respect to the same set of instructional components. One important way that the classrooms differed was with respect to the methods and materials that each teacher considered to be the core of his or her pedagogy (e.g., one teacher's instruction centered on trade books and process writing, another's on cooperative exploration as part of theme-driven instruction). There were also some striking omissions noted in the instruction observed, including a lack of instruction.
Designing Implementation and Communication Approaches in IT Project Management

This paper is a conceptual, research-in-progress study of the nature and role of communication in IT implementation projects. The paper considers different approaches to the implementation of change and to communication, and argues that scant attention is given to the design of communication approaches and strategies suitable for IT projects and other change initiatives. Arguments are developed to suggest that the most frequently used approaches to both implementation and communication are the least likely to be perceived to be successful, and those approaches to implementation and communication associated with greater acceptance of change are less likely to be used. We then map different approaches to implementation against different approaches to communication and argue that designing participative approaches to both implementation and communication are likely to result in better outcomes. The resulting conceptual model of communication approaches is then discussed with reference to a planned action research study of an enterprise system (ES) implementation in a global manufacturing company.
Co‐evolutionary analysis: a policy exploration method for system dynamics models

In system dynamics (SD), complex nonlinear systems can generate a wide range of possible behaviours that frequently require search and optimization algorithms in order to explore optimal policies. Within the SD literature, the conventional approach to optimization is the formulation of a single objective function, with a targeted parameter list, and the entire model is simulated repeatedly in order to arrive at optimum values. However, many sector-based SD models contain heuristics of “intended rationality”, and a desired outcome for modellers to be able to explore the policy implications of locally rational behaviours. This can now be achieved through a method known as coevolution, which allows modellers to divide an unsolved problem into constituent parts, where each part can be solved with respect to its own fitness function. In this paper, we specify a solution for evolving locally rational strategies across a multi-sector SD structure. Using the beer distribution game (BDG) as an illustration, we demonstrate the utility of this approach in terms of the impact of two different order management strategies on the policy space of the BDG.

Detecting product splittings of CAT(0) spaces

Let $X$ be a proper CAT($0$) space and $G$ a cocompact group of isometries of $X$ without fixed point at infinity. We prove that if $\partial X$ contains an invariant subset of circumradius $\pi/2$, then $X$ contains a quasi-dense, closed convex subspace that splits as a product. Adding the assumption that the $G$-action on $X$ is properly discontinuous, we give more conditions that are equivalent to a product splitting. In particular, this occurs if $\partial X$ contains a proper nonempty, closed, invariant, $\pi$-convex set in $\partial X$; or if some nonempty closed, invariant set in $\partial X$ intersects each round sphere $K \subset \partial X$ inside a proper subsphere of $K$.
A Statistical Model for Urban Radio Propogation

A statistical model, based on extensive experimental data, was established to characterize the urban radio propagation medium in various urban environments. Describing the medium by a linear filter, the peaks of the multipath response were analyzed statistically concerning the distribution of the path strength and the path arrival time. The statistical properties of these quantities depend on the modulation delay time. The resulting model can be used for simulation experiments in order to avoid costly hardware tests of ad hoc systems.
Development of a lemon sorting system based on color and size.

Grading systems give us many kinds of information such as size, color, shape, defect, and internal quality. Among these color and size are the most important features for accurate classification and/or sorting of citrus such as oranges, lemons and tangerines. Basically, two inspection stages of the system can be identified: external fruit inspection and internal fruit inspection. The former task is accomplished through processing of color images, while internal inspection requires special sensors for moisture, sugar and acid contents. In this paper, an efficient algorithm for grading lemon fruits is developed and implemented in visual basic environment. The system consists of two CCD cameras, two capture cards, an appropriate lighting system, a personal computer and other mechanical parts. The algorithm initially extracts the fruit from the background. The samples of different grades of lemon are situated in front of the cameras and are calibratted off-line. Then information on the HSI color values and estimated volumes of fruits are extracted and saved in a database. By comparing the information during sorting phase with the available information inside the database, the final grade of the passing fruits are determined. This algorithm can be easily adapted for grading and/or inspection of other agricultural products such as cucumber and eggplant. Key words: Lemon, sorting, volume, image processing, machine vision, HSI color.
Design and Experiment Results of High‐Speed Wireless Link Using Sub‐terahertz Wave Generated by Photonics‐Based Technology

Using a sub‐terahertz (sub‐THz) wave generated using a photonics‐based technology, a high‐speed wireless link operating at up to 10 Gbps is designed and demonstrated for realization of seamless connectivity between wireless and wired networks. The sub‐THz region is focused upon because of the possibility to obtain sufficient bandwidth without interference with the allocated RF bands. To verify the high‐speed wireless link, such dynamic characteristics as the eye diagrams and bit error rate (BER) are measured at up to 10 Gbps for non‐return‐to‐zero pseudorandom binary sequence 231−1 data. From the measurement results, a receiver sensitivity of –23.5 dBm at BFR=10−12 is observed without any error corrections when the link distance between the transmitter and receiver is 3 m. Consequently, we hope that our design and experiment results will be helpful in implementing a high‐speed wireless link using a sub‐THz wave.
Speakers, addressees, and frames of reference: Whose effort is minimized in conversations about locations?

When speakers describe locations, they must choose among taking their own perspective, their addressee's, a shared frame of reference, and a neutral frame of reference that avoids the issue, among other options. This study examines whether speakers choose spatial perspectives that minimize effort for themselves, for their partners, or for both. It also examines whether perspectives are taken for particular individuals, for the speaker or addressee, or for the person who knows the information to be communicated. Three possible models are proposed for exactly how descriptions in a particular perspective are more difficult when speaker and addressee view a scene from different offsets. In a communication task, speakers described locations on a complex display for addressees who shared their vantage point or were offset by 90° or 180°. In these conversations, both partners either took the perspective of the person who did not know the location or used descriptions that helped them avoid choosing one or the ot.
Identification of human postural dynamics

Human postural dynamics was investigated for six healthy subjects using a force platform recording body sway induced by vibrators attached to the calf muscles. The model of body mechanics adopted was that of an inverted pendulum, the dynamics of postural control being assumed to be reflected in the stabilizing forces exerted on the platform by the feet as a result of complex muscular activity subject to state feedback of body sway and position. The approach to signal processing has been that of parametric identification of a transfer function representing the stabilized inverted pendulum. Posture control was quantified in three variables: swiftness, stiffness, and damping. It is shown that the identification fulfils ordinary statistical validation criteria, and it is conjectured that the state feedback parameters identified are suitable for use in assessing ability to maintain posture. <<ETX>>
Reading relative clauses in English

Abstract Two self-paced reading experiments investigated several factors that inﬂuence the comprehension complexity of singly-embedded relative clauses (RCs) in English. Three factors were manipulated in Experiment 1, resulting in three main effects. First, object-extracted RCs were read more slowly than subject-extracted RCs, replicating previous work. Second, RCs that were embedded within the sentential complement of a noun were read more slowly than comparable RCs that were not embedded in this way. Third, and most interestingly, object-modifying RCs were read more slowly than subject-modifying relative clauses. This result contradicts one of the central tenets of complexity research: that nested sentences are harder to understand than their right-branching equivalents (e.g., Miller and Chomsky 1963). It is hypothesized that this result followed from a combination of two information-ﬂow factors: (1) background information is usually presented early in a sentence; and (2) restrictive RCs—the form of the RCs in Experiment 1—usually convey background information. Experiment 2 tested this hypothesis by comparing restrictive and non-restrictive RCs— which generally provide new information—in both subject- and objectmodifying positions. The results of the experiment were as predicted by the information-ﬂow account: Only restrictive RCs were read more slowly when modifying objects. It is concluded that both resource and information-ﬂow factors need to be considered in explaining RC complexity effects.
The use of lidar‐detected smoke puff evolution for dispersion calculations

Dispersion modelling is a key component of modern emergency responses to catastrophic atmospheric releases. However, periodic algorithmic advances are needed to effectively use new datasets acquired with modern remote sensing instruments. This work demonstrates that coherent Doppler lidar can be used to provide valuable new inputs for dispersion models. While related research seeks to retrieve other required inputs for dispersion modelling systems, for example velocity vectors from radial velocities, this paper assembles and contextualizes analytical and algorithmic approaches for an improved understanding of dispersion characteristics in specific atmospheric scenarios using Doppler lidar data. Longitudinal (along‐wind), lateral (cross‐wind), and vertical dispersion parameters are calculated and used to estimate eddy diffusivities based on Gaussian curve fitting and first‐order closure. Empirical relations based on similarity theory are used to verify these estimates, and reasonable agreement is found between the two approaches. Several improvements are also suggested for the lidar scanning techniques to facilitate retrieval of dispersion parameters. Copyright © 2010 Royal Meteorological Society
Design and analysis of low-power 10-transistor full adders using novel XOR-XNOR gates

Full adders are important components in applications such as digital signal processors (DSP) architectures and microprocessors. In this paper, we propose a technique to build a total of 41 new 10-transistor full adders using novel XOR and XNOR gates in combination with existing ones. We have done over 10,000 HSPICE simulation runs of all the different adders in different input patterns, frequencies, and load capacitances. Almost all those new adders consume less power in high frequencies, while three new adders consistently consume on average 10% less power and have higher speed compared with the previous 10-transistor full adder and the conventional 28-transistor CMOS adder. One draw back of the new adders is the threshold-voltage loss of the pass transistors.
Credulous Modellers and Suspicious Experimentalists? Comparison of Model Output and Data in Meteorological Simulation Modelling

This article studies the relation between two specialised practices in meteorology, modelling and field measurements. This relation is embodied in a number of joint practices of which model evaluation is one of them. The relationship between theory, model and observation has been of concern for many philosophers of science whereas the relationship between the working practices that underlie theories, models and observations, has received less attention. This paper describes and compares the practices that generate observation data and model output and the way different roles that fieldworkers and modellers have in this process are established. Next, different practice-oriented perspectives on the status of models, data and experiments are analysed and the discussion then moves on to the different trouble-shooting strategies scientists deploy, depending on their position within the discipline. It is shown that these strategies are often based on the ideas and judgements that modellers and experimentalists express about each other, and by implication, about their own role in the meteorological enterprise.
