THIS PROTEST WILL BE TWEETED

This article examines the use of Twitter at protests surrounding the G20 meetings held in Pittsburgh, PA in September 2009. Based on work on information communication technologies and protest, and on more recent work on Twitter usage at protests, we develop several hypotheses about the content of tweets during protests. Most significantly, we argue that Twitter is a widely available mobile social networking tool that can be used to reduce information asymmetries between protesters and police. Examining the content of 30,296 tweets over a nine-day period, we find that protesters frequently used Twitter to share information, including information about protest locations, as well as the location and actions of police, which is information that was formerly monopolized by the police. Twitter use may be creating a new dynamic in protester and police interaction toward information symmetries. We conclude by identifying implications for policing practices and for protesters.
Characteristics of baseband digital signal transmission for intrabody communications

Intrabody communications (IBC) is a new physical layer outlined in the recently ratified IEEE 802.15. 6 Wireless Body Area Network (WBAN) standard. This data communication method uses the human body itself as the signal propagation medium. It is significant to investigate the signal characteristics for baseband digital data transceiver design in IBC. In this paper, we present preliminary channel attenuation characteristics of a time division multiple access (TDMA) scheme implemented based on baseband digital signal transmission. A digital block implemented on a field-programmable gate array (FPGA) board as well as a digital Pulse Generator are employed as the IBC transmitters. The timeslot occupancy is simulated by adjusting the duty cycle of a square wave of varying frequencies. The measurements using FPGA indicate the signal attenuation of 32.76 and 27.82 dB at frequency of 10 and 25 MHz, respectively, for digital signals with 50% duty cycle. In addition, the attenuation of signal with 20% and 50% duty cycle at 50 MHz are 32.76 and 30.63 dB when Pulse Generator is used as the IBC transmitter. The variation of duty cycle in pulses was then used to simulate a time division multiplexed transmission scheme. It was observed that the attenuation decreases around 4.0 dB when data pulses are increasingly present from 1 to 5 timeslots. Therefore, digital baseband signals deployed in a time division multiplexed mode with higher timeslot occupancy leads to lower attenuation for IBC transmissions.
C RYSTAL I SLAND : A Narrative-Centered Learning Environment for Eighth Grade Microbiology

Narrative-centered learning environments offer significant promise for promoting interactive learning experiences that are both effective and engaging. Models of narrative generation and reasoning can balance the motivational and pedagogical aspects of narrative-centered learning interactions. Affect recognition and affect expression models are useful for shaping students’ affective trajectories during narrative-centered learning. Conducting empirical evaluations are critical for determining what factors contribute to the potential pedagogical and motivational benefits of narrative-centered learning environments. This paper presents an overview of progress in these areas by summarizing work on C RYSTAL I SLAND , a narrative-centered learning environment for eighth grade microbiology.
Towards the Next Generation of Tabletop Gaming Experiences

In this paper we present a novel hardware and software platform (STARS) to realize computer augmented tabletop games that unify the strengths of traditional board games and computer games. STARS game applications preserve the social situation of traditional board games and provide a tangible interface with physical playing pieces to facilitate natural interaction. The virtual game components offer exciting new opportunities for game design and provide richer gaming experiences impossible to realize with traditional media.This paper describes STARS in terms of the hardware setup and the software platform used to develop and play STARS games. The interaction design within STARS is discussed and sample games are presented with regard to their contributions to enhancing user experience. Finally, real-world experiences with the platform are reported.
Analysis of the impact of temporal, spatial, and quantization variations on perceptual video quality

The growing consumer interest in video communication has increased the users' awareness in the visual quality of the delivered media. This in turn increases, at the service provider end, the need for intelligent methodologies of optimal techniques for adapting to varying network conditions. Recent studies show that constraints on the bandwidth of transmission media should not always be translated to an increase in compression ratio to lower the bitrate of the video. Instead, a suitable option for adaptive streaming is to scale down the video temporally or spatially before encoding to maintain a desirable level of perceptual quality, while the viewing resolution is constant. Most of the existing studies to examine these scenarios are either limited to low resolution videos or lack in provisioning of subjective assessment of quality.We present here the results of our campaign of subjective quality assessment experiments done on a range of spatial and temporal resolutions, up to VGA and 30 frames per second respectively, under a number of bitrate conditions. The analysis shows, among other things, that keeping the spatial resolution is perceptually preferred among the three parameters that have impact on the video quality, even in the case with high temporal activity.
Gender-Based Domestic Violence against Children: Experiences of Girl-Children in Nigeria

This study investigated the dynamics of gender-based domestic violence against children in Nigeria. This qualitative study explored the experiences of 20 purposively selected girl-children (age range = 12 to 15 years) from two SOS Children's Village who have been victims of Domestic Violence (DV). Qualitative data on DV experiences and associated factors were collected through 6 Focus Group Discussions (FGDs). Physical violence was reported by 90% of the participants; psychological abuse by 80% and violent sexual abuse (rape) by 10%. Major factors associated with last episode of DV experiences included: inability to finish selling wares that were being hawked, late preparation of food, getting home late from the market, burning of the employer's cloth while ironing, refusal to be genitally cut and refusal to be raped by the man of the house. Self-reported consequences of DV by victims included amongst others: constant headaches (30%) physical injury (25%), sleep disturbances (20%), excessive fear and anxiety (10%), hatred for men (10%) and suicidal ideation (5%). These findings suggest that DV may be playing significant but salient role in the poor state of health of Nigerian children and effective intervention processes at all levels are needed to address it.
Embryonic and adult stem cells promote raphespinal axon outgrowth and improve functional outcome following spinal hemisection in mice

Spinal cord injury (SCI) often results in permanent neurological deficits below the injury site. Serotonergic raphespinal projections promote functional recovery after SCI, but spontaneous regeneration of most severed axons is limited by the glial cyst and scar that form at the lesion site. Stem cell (SC) transplantation offers a promising approach for inducing regeneration through the damaged area. Here we compare the effects of transplantation of embryonic neural precursors (NPs) or adult mesenchymal SCs, both of which are potential candidates for SC therapy. The spinal cord was hemisected at the L2 neuromer in adult mice. Two weeks post‐injury, we transplanted neural precursors or mesenchymal SCs into the cord, caudal to the hemisection. Injured mice without a graft served as controls. Mice were tested for functional recovery on a battery of motor tasks, then killed and analysed for survival of grafted cells, for effects of engraftment on the local cellular environment and for the sprouting of serotonergic axons. Both types of SCs survived and were integrated into the host tissue, but only the NPs expressed neuronal markers. All transplanted animals displayed an increased number of serotonin‐positive fibres caudal to the hemisection, compared with untreated mice. And both cell types led to improved motor performance. These results point to a therapeutic potential for such cell grafting.
Three-Dimensional Buoyant Turbulent Flows in a Scaled Model, Slot-Ventilated, Livestock Confinement Facility

A three-dimensio nal turbulence model was used to determine the effects of animal-genera ted buoyant forces on the airflow patterns and temperature and airspeed distributions in a ceiling-slot, ventilated, swine grower facility. The model incorporated the Lam-Bremhorst turbulence model for low-Reynolds Number airflow typical of slot-ventilated, livestock facilities. The predicted results from the model were compared with experimental results from a scaled-enclosu re. The predicted and measured results indicated a rather strong cross-stream recirculation zone in the chamber that resulted in substantial threedimensional temperature distributions for moderate to highly buoyancy-affected flows. Airflow patterns were adequately predicted for Ar^ > 40 and J values 0.00053, the visualized patterns indicated that the jet separated from the ceiling before the opposing end-wall. This discrepancy was attributed to variations in the experimental and numerical inlet flow development assumptions.
Towards a Cultural–Clinical Psychology

For decades, clinical psychologists have catalogued cultural group differences in symptom presentation, assessment, and treatment outcomes. We know that ‘culture matters’ in mental health – but do we know how it matters, or why? Answers may be found in an integration of cultural and clinical psychology. Cultural psychology demands a move beyond description to explanation of group variation. For its part, clinical psychology insists on the importance of individual people, while also extending the range of human variation. Cultural–clinical psychology integrates these approaches, opening up new lines of inquiry. The central assumption of this interdisciplinary field is that culture, mind, and brain constitute one another as a multi-level dynamic system in which no level is primary, and that psychopathology is an emergent property of that system. We illustrate cultural–clinical psychology research using our work on depression in Chinese populations and conclude with a call for greater collaboration among researchers in this field.
What counts as knowledge in teacher education

The field of education generally, and teacher education particularly, is experiencing some general disquiet with traditional approaches to the identification and classification of knowledge. Formal research studies, long the source of the knowledge base of teaching, is discredited by new ideologies that are based in the women's movement, the multiculturalists, and persons taken up with newer research strategies called naturalistic, ethnographic, or case study approaches. The book is a collection of essays that rehearses the issues facing the field, and addresses them in forthright fashion.
Discrimination between Alzheimer's Disease and Mild Cognitive Impairment Using SOM and PSO-SVM

In this study, an MRI-based classification framework was proposed to distinguish the patients with AD and MCI from normal participants by using multiple features and different classifiers. First, we extracted features (volume and shape) from MRI data by using a series of image processing steps. Subsequently, we applied principal component analysis (PCA) to convert a set of features of possibly correlated variables into a smaller set of values of linearly uncorrelated variables, decreasing the dimensions of feature space. Finally, we developed a novel data mining framework in combination with support vector machine (SVM) and particle swarm optimization (PSO) for the AD/MCI classification. In order to compare the hybrid method with traditional classifier, two kinds of classifiers, that is, SVM and a self-organizing map (SOM), were trained for patient classification. With the proposed framework, the classification accuracy is improved up to 82.35% and 77.78% in patients with AD and MCI. The result achieved up to 94.12% and 88.89% in AD and MCI by combining the volumetric features and shape features and using PCA. The present results suggest that novel multivariate methods of pattern matching reach a clinically relevant accuracy for the a priori prediction of the progression from MCI to AD.
A Novel Missense Mutation in ADAMTS10 in Norwegian Elkhound Primary Glaucoma

Primary glaucoma is one of the most common causes of irreversible blindness both in humans and in dogs. Glaucoma is an optic neuropathy affecting the retinal ganglion cells and optic nerve, and elevated intraocular pressure is commonly associated with the disease. Glaucoma is broadly classified into primary open angle (POAG), primary closed angle (PCAG) and primary congenital glaucoma (PCG). Human glaucomas are genetically heterogeneous and multiple loci have been identified. Glaucoma affects several dog breeds but only three loci and one gene have been implicated so far. We have investigated the genetics of primary glaucoma in the Norwegian Elkhound (NE). We established a small pedigree around the affected NEs collected from Finland, US and UK and performed a genome-wide association study with 9 cases and 8 controls to map the glaucoma gene to 750 kb region on canine chromosome 20 (praw = 4.93×10−6, pgenome = 0.025). The associated region contains a previously identified glaucoma gene, ADAMTS10, which was subjected to mutation screening in the coding regions. A fully segregating missense mutation (p.A387T) in exon 9 was found in 14 cases and 572 unaffected NEs (pFisher = 3.5×10−27) with a high carrier frequency (25.3%). The mutation interrupts a highly conserved residue in the metalloprotease domain of ADAMTS10, likely affecting its functional capacity. Our study identifies the genetic cause of primary glaucoma in NEs and enables the development of a genetic test for breeding purposes. This study establishes also a new spontaneous canine model for glaucoma research to study the ADAMTS10 biology in optical neuropathy.
Serial Killers: Death and Life in America's Wound Culture

In this provocative cultural study, the serial killer emerges as a central figure in what Mark Seltzer calls 'America's wound culture'. From the traumas displayed by talk show guests and political candidates, to the violent entertainment of Crash or The Alienist, to the latest terrible report of mass murder, we are surrounded by the accident from which we cannot avert our eyes. Bringing depth and shadow to our collective portrait of what a serial killer must be, Mark Seltzer draws upon popular sources, scholarly analyses, and the language of psychoanalysis to explore the genesis of this uniquely modern phenomenon. Revealed is a fascination with machines and technological reproduction, with the singular and the mass, with definitions of self, other, and intimacy. What emerges is a disturbing picture of how contemporary culture is haunted by technology and the instability of identity.
Host Quality and Spatial Patterning in Infections of the Eastern Mudsnail (Ilyanassa obsoleta) by Two Trematodes (Himasthla quissetensis and Zoogonus rubellus)

Abstract: Several studies have suggested that the fitness of a parasite can be directly impacted by the quality of its host. In such cases, selective pressures could act to funnel parasites towards the highest-quality hosts in a population. The results of this study demonstrate that snail host quality is strongly correlated with spatial patterning in trematode infections and that habitat type is the underlying driver for both of these variables. Two trematodes (Himasthla quissetensis and Zoogonus rubellus) with very different life cycles assume the same spatial infection pattern in populations of the first intermediate host (Ilyanassa obsoleta) in coastal marsh habitats. Infected snails are disproportionately recovered from intertidal panne habitats, which offer more hospitable environs for snails than do adjacent habitats (intertidal creeks, coastal flats, and subtidal creeks), in terms of protection from turbulence and wave action, as well as the availability of food stuffs. Snails in intertidal panne habitats are of higher quality when assessed in terms of average size-specific mass, growth rate, and fecundity. In mark–recapture experiments, snails frequently dispersed into intertidal pannes but were never observed leaving them. In addition, field experiments demonstrate that snails confined to intertidal panne habitats are disproportionately infected by both trematode species, relative to conspecifics confined to adjacent habitats. Laboratory experiments show that infected snails suffer significant energetic losses and consume more than uninfected conspecifics, suggesting that infected snails in intertidal pannes may survive better than in adjacent habitats. We speculate that 1 possible mechanism for the observed patterns is that the life cycles of both trematode species allows them to contact the highest-quality snails in this marsh ecosystem.
Phase diagrams of one-, two-, and three-dimensional quantum spin systems

We study the bipartite entanglement per bond to determine characteristic features of the phase diagram of various quantum spin models in diﬀerent spatial dimensions. The bipartite entanglement is obtained from a tensor network representation of the ground state wave-function. Three spin-1/2 models (Ising, XY, XXZ, all in a transverse (cid:12)eld) are investigated. In(cid:12)nite imaginary-time evolution (iTEBD in 1D, ‘simple update’ in 2D and 3D) is used to determine the ground states of these models. The phase structure of the models is discussed for all three dimensions.
Hemagglutinin Stalk-Reactive Antibodies Are Boosted following Sequential Infection with Seasonal and Pandemic H1N1 Influenza Virus in Mice

ABSTRACT Previously, it has been shown that infection in humans with the pandemic swine influenza virus induces antibodies with specificity to the stalk domain of the viral hemagglutinin. Following the generation of these data, we sought to recapitulate these findings in the mouse model by sequential influenza virus infection. Mice that were inoculated with a seasonal influenza H1N1 virus followed by infection with a pandemic H1N1 strain produced higher antihemagglutinin stalk antibody titers than mice sequentially infected with drifted seasonal strains. In order to achieve antibody titers of comparable magnitude using sequential infection, mice had to be infected with 100- to 1,000-fold more of the drifted seasonal virus. The antistalk antibodies produced by these infections were influenza virus neutralizing, which illustrates the utility of the mouse model in which to study this interaction between virus and host.
Line-Members - a Novel Feature in On-Line Whiteboard Note Recognition

Confusion-matrices show that character mix-ups between similar looking letters differing in size rather than in shape (like “s” and “S” or “e” and “l”), as well as between tall letters (such as “M” and “t”) and small case letters (such as “s” and “a”) and vice versa can occur in on-line whiteboard note recognition. This paper introduces a novel feature called “line-member” feature that adds discriminance to the feature vector. Thereby, for certain sample points the script line association is estimated using the Viterbi algorithm and taken as a feature. As our experiments indicate, a relative improvement of r = 3.3 % in character level and r = 3.4 % in word level accuracy compared to a baseline system without the novel “line-member” feature can be achieved. In addition, the character confusion as described above can be reduced.

Adjusting for Perception Bias in Citizens' Subjective Evaluations

Citizen surveys have been increasingly employed to evaluate the outcome of public service delivery. However, the effects of respondents' demographic characteristics on their subjective evaluations inevitably raise questions about the fairness of such investigations. This study views the accumulation of citizen perception as a production process and proposes a generic model for adjusting for demographic effects from a production function perspective. The paper uses household survey data from the World Bank for five of China's cities to examine the efficacy of the proposed model. The results confirm that most demographic characteristics, including age, health status, education, and sex, consistently have a statistically significant effect on satisfaction scores. Furthermore, after I adjust for respondent characteristics, the city rankings change in some satisfaction settings,making the rankings more reflective of reality. The power of the proposed model is further justified by adjusting the satisfaction scores of five cities' households for the TV program Spring Festival Party, an identical service to each household that is provided by the single public service agent,CCTV
Identification of Healthy and BSR-Infected Oil Palm Trees Using Color Indices

Abstract—Most of the oil palm plantations have been threatened by Basal Stem Rot (BSR) disease which causes serious economic impact. This study was conducted to identify the healthy and BSRinfected oil palm tree using thirteen color indices. Multispectral and thermal camera was used to capture 216 images of the leaves taken from frond number 1, 9 and 17. Indices of normalized difference vegetation index (NDVI), red (R), green (G), blue (B), near infrared (NIR), green – blue (GB), green/blue (G/B), green – red (GR), green/red (G/R), hue (H), saturation (S), intensity (I) and thermal index (T) were used. From this study, it can be concluded that G index taken from frond number 9 is the best index to differentiate between the healthy and BSR-infected oil palm trees. It not only gave high value of correlation coefficient (R=-0.962), but also high value of separation between healthy and BSR-infected oil palm tree. Furthermore, power and S model developed using G index gave the highest R value which is 0.985.
