Tweeting Government: A Case of Australian Government Use of Twitter

Since its launch in 2006, Twitter has gained considerable popularity among professionals, celebrities and lately by organisations and governments. The application of Twitter in enterprises has been discussed in both practice and academia. However there are few publications on government use of Twitter, in particular for Australian government. This research-in-progress paper investigates Australian government use of Twitter and seeks to understand government Twitter use phenomenon. Six government agency tweets were analysed to understand the communicative practices and types of use by the agencies. The analysis shows that agencies are primarily using Twitter to disperse information, particularly links to news articles about themselves, and to report on their activities. Further citizen interaction is also analysed within these agencies by analysing citizen tweets aimed at these agencies. The paper aims to contribute to better understanding of the government Twitter phenomenon on the public Social Network Site (SNS) that can lead to useful conclusions for government agency adoption and usage of Twitter.
Does internal quality management contribute to more control or to improvement of higher education? A survey on faculty's perceptions

Purpose – The purpose of this paper is to explore faculty's perceptions of quality management activities (QMA) within their departments, attention being paid to relevant quality aspects and whether quality management contributes to control or improvement of higher education. Furthermore, it examines differences between departments and relationships between the different variables.Design/methodology/approach – A questionnaire containing items with Likert‐type answer scales was distributed to faculty (n=266) of 18 departments of universities of applied sciences in the Netherlands: 16 items dealt with QMA, 17 with attention paid to relevant quality aspects and ten with the perceived effects.Findings – Faculty were neutral about the degree to which sufficient QMA were conducted within their departments. They were positive about the attention paid to relevant quality aspects. Furthermore, they were positive about the effects in terms of improvement and negative about the effects in terms of control.

Solution-Processed Quantum Dot Photodetectors

Digital imaging has traditionally been enabled by single-crystalline photodetectors. This approach typically either mandates the use of silicon as photon-to-electron converter or requires a hybrid-integrated solution. In contrast, solution-processed optoelectronic materials offer convenient integration of light-sensing materials atop an electronic readout circuit. Colloidal quantum dots offer particular advantages, combining solution-processing with the spectral tunability afforded by the quantum size effect. Here we review recent progress in solution-processed quantum dot photodetectors and their application in future imaging systems. We focus on progress towards high responsivity (photon-to-electron gains exceeding 1000) and sensitivity (normalized detectivity D* ~ 1013Jones) in the visible, the near infrared, and the short-wavelength infrared. We also highlight the achievement of solution-processed photoconductive photodetectors combining photoconductive gain and temporal responses faster than 30 ms, devices therefore compatible with video-frame-rate imaging. We conclude with a discussion of recent colloidal quantum dot photodiodes having megahertz bandwidth and detectivity of 1011 Jones.

Grammar Modularity and its Impact on Grammar Documentation

This paper addresses the documentation of large-scale grammars. We argue that grammar implementation differs from ordinary software programs: the concept of modules, as known from software engineering, cannot be transferred directly to grammar implementations, due to grammar-specific properties. These properties also put special constraints on the form of grammar documentation. To fulfill these constraints, we propose an XML-based, grammar-specific documentation technique.
Teachers labour process : proletarianisation and the Greek case

The focus of the thesis is teachers' labour process in upper secondary education in Greece, as this is structured by the introduction of prescribed and standardized curricula. At the centre of our theoretical approach lies the Marxian theory of labour process and its development of the proletarianisation thesis.The theoretical approach, that is adopted by this study, is a critical approach to the labour process theory and its proletarianisation thesis. The labour process theory, we argue, studies teachers' labour process by particularly focusing on the introduction of predetermined and standardized curricula which, as is argued, result in teachers' proletarianisation, that is to say teachers' autonomy is restricted and they are not able to exercise any control on their labour process. Our theoretical reservations, as far as the labour theory is concerned, are related to the way teachers' labour process is conceived and understood. More specifically, we argue, that labour process theory does not conceive teachers' labour process as a production process and consequently does not take into consideration the production relations, in and of production. Hence this study argues that teachers' labour process is shaped, apart from the curriculum, by the parameter "students" and to be more concrete, by "students' cultural capital" and habitus towards knowledge. Without taking into consideration and theorizing the factor "students", labour process theory, we argue, is unable to conceive and understand the "production relations", developed in the classroom, namely the relations developed between teachers and curriculum as relations mediated by students' presence. In short labour process theory has a narrow concept of "skill" and "de-skilling". Finally, we argue, as our findings indicate, that proletarianisation should be theorized and conceptualized not as a homogeneous process but should be seen as a process which is characterized by variations in its modalities, in relation to particular sociohistorical conjunctures.
A unified theory for the energy cost of legged locomotion

Small animals are remarkably efficient climbers but comparatively poor runners, a well-established phenomenon in locomotor energetics that drives size-related differences in locomotor ecology yet remains poorly understood. Here, I derive the energy cost of legged locomotion from two complementary components of muscle metabolism, Activation–Relaxation and Cross-bridge cycling. A mathematical model incorporating these costs explains observed patterns of locomotor cost both within and between species, across a broad range of animals (insects to ungulates), for a wide range of substrate slopes including level running and vertical climbing. This ARC model unifies work- and force-based models for locomotor cost and integrates whole-organism locomotor cost with cellular muscle physiology, creating a predictive framework for investigating evolutionary and ecological pressures shaping limb design and ranging behaviour.
Comparison of the hepatic clearances of campesterol, sitosterol, and cholesterol in healthy subjects suggests that efflux transporters controlling intestinal sterol absorption also regulate biliary secretion

Background: Recently identified ABCG5/8 transporters are responsible in part for the different absorption rates of campesterol, sitosterol, and cholesterol. These transporters are also expressed in the liver and might regulate biliary sterol secretion. Aims: This study was therefore conducted to determine the biliary secretion rates and hepatic clearances of campesterol, sitosterol, and cholesterol. Subjects: Six healthy, male volunteers. Methods: Deuterium labelled sitosterol and campesterol, and unlabelled sitostanol were constantly infused together with a liquid formula using a duodenal perfusion technique. Biliary secretion and hepatic clearance rates were calculated from hourly bile and plasma samples. Results: Plasma concentrations of cholesterol, campesterol, and sitosterol averaged 167.5 (50) mg/dl (SD), 0.50 (0.22) mg/dl, and 0.30 (0.10) mg/dl, respectively. Sitosterol showed a significantly higher biliary secretion rate (1.23 (0.87) mg/h) than campesterol (0.76 (0.54) mg/h, p=0.0321), but both plant sterols had significantly lower biliary secretion rates compared with cholesterol (47.7 (17.5) mg/h; p=0.001 for both). Hepatic clearance of cholesterol (0.31 (0.18) dl/h) was significantly lower compared with campesterol (2.11 (2.51) dl/h) and sitosterol (4.97 (4.70) dl/h; p=0.028 for both), and the clearance of campesterol was significant lower compared with sitosterol (p=0.028). Conclusion: The observed inverse relation between hepatic clearance and known intestinal absorption of cholesterol, campesterol, and sitosterol supports the hypothesis that the ABCG5/8 transporters regulating intestinal sterol absorption might also be involved in biliary sterol excretion.
Functional Organization of the Golgi Apparatus in Glycosphingolipid Biosynthesis

Biosynthesis of plasma membrane sphingolipids involves the coordinate action of enzymes localized to individual compartments of the biosynthetic secretory pathway of proteins. These stations include the endoplasmic reticulum and the Golgi apparatus. Although a precise localization of all the enzymes that synthesize glycosphingolipids has not been achieved to date, it is assumed that the sequence of events in glycosphingolipid biosynthesis resembles that in glycoprotein biosynthesis, i.e. that early reactions occur in early stations (endoplasmic reticulum and cis/medial Golgi) of the pathway, and late reactions occur in late stations (trans Golgi/trans Golgi network). Using truncated analogues of ceramide and glucosylceramide that allow measurement of enzyme activities in intact membrane fractions, we have reinvestigated the localization of individual enzymes involved in glycosphingolipid biosynthesis and for the first time studied the localization of lactosylceramide synthase after partial separation of Golgi membranes as previously described (Trinchera, M., and Ghidoni, R. (1989) J. Biol. Chem. 264, 15766–15769). Here, we show that the reactions involved in higher glycosphingolipid biosynthesis, including lactosylceramide synthesis, all reside in the lumen of the late Golgi compartments from rat liver.

Low Diameter Unicast On-Chip Interconnection Networks for Many-Core Embedded Systems

It is critical for the network-on-chip in embedded multi-core and many-core chips to be scalable while limiting power consumption. With the router power dominating the network's power, one way to achieve this goal is by the design of on-chip interconnection networks with small diameters and simple routing. Herein, we present a few new unicast on-chip networks for interconnecting the cores with diameters superior to the popular 2D mesh.
A Survey on Inductive Learning

Inductive learning is the method of learning from observations. Inductive learning has important applications over a wide range of area including pattern recognition, language acquisition, bio-informatics and intelligent agent design. Because of such diverse applicability, inductive learning methods including automata learning, grammar induction, hidden markov model learning and symbolic statistical modeling have attracted the attention of researchers for several decades. Consequently, inductive learning continues to be a major focus of research. This report surveys some of the key results in automata learning, grammar induction, hidden markov model learning and symbolic statistical modeling. Different learning problems are critically compared to emphasize their usability for various applications. Learning from example sequences has been illustrated by implementing automata learning techniques to learn a process model to capture users browsing behavior in Web transactions. Experimental evaluation of the learned model is also reported. Possible future research is to incorporate grammar induction and symbolic statistical learning in rule based systems.
Linguistic politeness in Britain and Uruguay

The first well-researched contrastive pragmatic analysis of requests and apologies in British English and Uruguayan Spanish. It takes the form of a cross-cultural corpus-based analysis using male and female native speakers of each language and systematically alternating the same social variables in both cultures. The data are elicited from a non-prescriptive open role-play yielding requests and apologies. The analysis of the speech acts is based on an adaptation of the categorical scheme developed by Blum-Kulka et al. (1989). The results show that speakers of English and Spanish differ in their choice of (in)directness levels, head-act modifications, and the politeness types of males and females in both cultures. Reference to an extensive bibliography and the thorough discussion of methodological issues concerning speech act studies deserve the attention of students of pragmatics as well as readers interested in cultural matters.
Normobaric hyperoxia inhibits NADPH oxidase‐mediated matrix metalloproteinase‐9 induction in cerebral microvessels in experimental stroke

Matrix metalloproteinase‐9 (MMP‐9) and NADPH oxidase contribute to blood–brain barrier (BBB) disruption after ischemic stroke. We have previously shown that normobaric hyperoxia (NBO) treatment reduces MMP‐9 and oxygen free radical generation in ischemic brain. In this study, we tested the hypothesis that NBO protects the BBB through inhibiting NADPH oxidase‐mediated MMP‐9 induction in transient focal cerebral ischemia. Male Sprague–Dawley rats (n = 69) were given NBO (95% O2) or normoxia (21% O2) during 90‐min filament occlusion of the middle cerebral artery. Cerebral microvessels were isolated for analyzing MMP‐9 and NADPH oxidase. BBB damage was non‐invasively quantified with magnetic resonance imaging. In normoxic rats, both NADPH oxidase catalytic subunit gp91phox and MMP‐9 expression were up‐regulated in ischemic hemispheric microvessels after 90‐min middle cerebral artery occlusion with 22.5 h reperfusion. Inhibition of NADPH oxidase with apocynin reduced the MMP‐9 increase, indicating a causal link between NADPH oxidase‐derived superoxide and MMP‐9 induction. NBO treatment inhibited gp91phox expression, NADPH oxidase activity, and MMP‐9 induction, which led to significantly less BBB damage and brain edema in the ischemic brain. These results suggest that gp91phox containing NADPH oxidase plays an important role in MMP‐9 induction in ischemic BBB microvasculature, and that NBO treatment may attenuate MMP‐9 induction and brain edema through inhibiting NADPH oxidase after transient cerebral ischemia.
A High-Speed Data Acquisition Subsystem

Many problems inherent in signal acquisition using laboratory minicomputers are overcome by using a high-speed data acquisition subsystem incorporating a large buffer memory. A structured systems development methodology details the design stages of this subsystem and its interfaces. Key to implementation of the design is a dual-port solid-state disk (extended memory unit). The subsystem operates at acquisition rates up to 125 000 samples/s and can be extended to 500 000 samples/s; its design permits operation with any real-time or time-shared operating system.
Noncommand user interfaces

ost current Uls are fairly similar and belong to one of two common types: either the traditional alphanumeric full-screen terminals with a keyboard and function keys, or the more modern WIMP workstations with windows,/cons, menus, and a pointing device. In fact, most UI standards released since 1983 have been remarkably similar, and it is that category of canonical windOw system that is referred to as "current" throughout this article. In contrast, the next generation of UIs may move beyond the standard WIMP paradigm to involve elements such as virtual realities, head-mounted displays, sound and speech, pen and gesture recognition, animation and multimedia, limited artificial intelligence, and highly portable computers with cellular or other wireless communication capabilities. It is difficult to envision the use of this hodgepodge of technologies in a single, united UI design, and indeed, it may be one of the defining characteristics of nextgeneration UIs that they abandon the principle of conforming to a canonical interface style and instead become more radically tailored to the requirements of individual tasks. In any case, all previous generations of UIS, whether batch-, line-oriented, full-screen, or WIMP, have all had one defining characteristic in common: They were all
Predicting Protein Subcellular Localizations for Gram-Negative Bacteria Using DP-PSSM and Support Vector Machines

Invisible bacteria are found almost everywhere, and having a great impact on our everyday life. Particularly, many species of gram-negative bacteria are pathogenic and cause a wide variety of diseases in humans and animals. It is crucial in drug design to cure diseases brought by gram-negative bacteria. Unfortunately, a new drug discovery can be expensive and time-consuming even with the advance of biotechnology. Designing a highly effective and efficient computational system, especially for identifying protein subcellular localization for gram-negative bacteria, is an important research field.In this paper, we propose a new computational system which combines a well-known classifier, support vector machines (SVMs), a protein descriptor, DP-PSSM (Directional Property-PSSM), and an optimal tool for system tuning. In addition, an evolutionary computation based feature selection technique is applied to further improve the performance of our computational system. Our computational system, EF-SVM-PSL, had been tested through 10 fold cross validation on predicting subcellular localizations of three gram-negative bacteria protein datasets, PS1444, NR828, and EV243. Our EF-SVM-PSL has a relative simple architecture and performs competitively with the best alternative systems.
Implementing mission critical services and applications on top of heterogeneous networks

We present an advanced and resilient solution for equipping first responders with survivable high-performance communications and Internet-of-Things (IoT) services in day-to-day operations and in disaster relief missions. The system provides intervention teams with transparent connectivity by leveraging any available professional, commercial or ad-hoc communication network using advanced future networking technologies, such as IPv6 and smart tunneling. First responders in action benefit from sensors and professional IoT services that assist and protect them during mission, based on-location tracking, triage reporting, vital signs monitoring and video feeds. In headquarters, professional intervention management software offers advanced services for real-time intervention monitoring, such as contextualized fleet tracking, visual sensor alerts and live video feeds from the field, as well as services to support international and cross-agency cooperation.
Complementarity and equivalent formulations via nonlinear programming : numerical results on multi-rigid-body contact problems with Coulomb friction ∗

In this work we show that the complementarity problems that model three-dimensional multi-rigid-body contact problems with friction may be formulated as equivalent nonlinear bound-constrained optimization problems. This transformation preserves the smoothness of the original problem, at the price of increasing the number of variables. One may thus take advantage of existing codes for bound-constrained optimization. Preliminary numerical results indicate the approach is promising.
Space-Time Adaptive Wavelet Methods for Optimal Control Problems Constrained by Parabolic Evolution Equations

An adaptive algorithm based on wavelets is proposed for the efficient numerical solution of a control problem governed by a linear parabolic evolution equation. First, the constraints are represented by means of a full weak space-time formulation as a linear system in $\ell_2$ in wavelet coordinates, following a recent approach by Schwab and Stevenson. Second, a quadratic cost functional involving a tracking-type term for the state and a regularization term for the distributed control is also formulated in terms of $\ell_2$ sequence norms of wavelet coordinates. This functional serves as a representer for a functional involving different Sobolev norms with possibly nonintegral smoothness parameter. Standard techniques from optimization are then used to derive the first order necessary conditions as a coupled system in $\ell_2$-coordinates. For this purpose, an adaptive method is proposed, which can be interpreted as an inexact gradient method for the control. In each iteration step, the primal and adjoint systems are solved up to a prescribed accuracy by the adaptive algorithm. It is shown that the adaptive algorithm converges. Moreover, the algorithm is proved to be asymptotically optimal: the convergence rate achieved for computing each of the components of the solution (state, adjoint state, and control) up to a desired target tolerance is asymptotically the same as the wavelet best $N$-term approximation of each solution component, and the total computational work is proportional to the number of computational unknowns.
