Seeing things in the clouds: the effect of visual features on tag cloud selections

Tag clouds are a popular method for visualizing and linking socially-organized information on websites. Tag clouds represent variables of interest (such as popularity) in the visual appearance of the keywords themselves - using text properties such as font size, weight, or colour. Although tag clouds are becoming common, there is still little information about which visual features of tags draw the attention of viewers. As tag clouds attempt to represent a wider range of variables with a wider range of visual properties, it becomes difficult to predict what will appear visually important to a viewer. To investigate this issue, we carried out an exploratory study that asked users to select tags from clouds that manipulated nine visual properties. Our results show that font size and font weight have stronger effects than intensity, number of characters, or tag area; but when several visual properties are manipulated at once, there is no one property that stands out above the others. This study adds to the understanding of how visual properties of text capture the attention of users, indicates general guidelines for designers of tag clouds, and provides a study paradigm and starting points for future studies. In addition, our findings may be applied more generally to the visual presentation of textual hyperlinks as a way to provide more information to web navigators.

Simulation results demonstrate an impressive resolution to power consumption ratio and a good immunity to environmental parameters. Experimental results finally demonstrate the efficiency of this promising read-out architecture.
Candidate Hippocampal Biomarkers of Susceptibility and Resilience to Stress in a Rat Model of Depression*

Susceptibility to stress plays a crucial role in the development of psychiatric disorders such as unipolar depression and post-traumatic stress disorder. In the present study the chronic mild stress rat model of depression was used to reveal stress-susceptible and stress-resilient rats. Large-scale proteomics was used to map hippocampal protein alterations in different stress states. Membrane proteins were successfully captured by two-phase separation and peptide based proteomics. Using iTRAQ labeling coupled with mass spectrometry, more than 2000 proteins were quantified and 73 proteins were found to be differentially expressed. Stress susceptibility was associated with increased expression of a sodium-channel protein (SCN9A) currently investigated as a potential antidepressant target. Differential protein profiling also indicated stress susceptibility to be associated with deficits in synaptic vesicle release involving SNCA, SYN-1, and AP-3. Our results indicate that increased oxidative phosphorylation (COX5A, NDUFB7, NDUFS8, COX5B, and UQCRB) within the hippocampal CA regions is part of a stress-protection mechanism.
Genomic islands: tools of bacterial horizontal gene transfer and evolution

Bacterial genomes evolve through mutations, rearrangements or horizontal gene transfer. Besides the core genes encoding essential metabolic functions, bacterial genomes also harbour a number of accessory genes acquired by horizontal gene transfer that might be beneficial under certain environmental conditions. The horizontal gene transfer contributes to the diversification and adaptation of microorganisms, thus having an impact on the genome plasticity. A significant part of the horizontal gene transfer is or has been facilitated by genomic islands (GEIs). GEIs are discrete DNA segments, some of which are mobile and others which are not, or are no longer mobile, which differ among closely related strains. A number of GEIs are capable of integration into the chromosome of the host, excision, and transfer to a new host by transformation, conjugation or transduction. GEIs play a crucial role in the evolution of a broad spectrum of bacteria as they are involved in the dissemination of variable genes, including antibiotic resistance and virulence genes leading to generation of hospital ‘superbugs’, as well as catabolic genes leading to formation of new metabolic pathways. Depending on the composition of gene modules, the same type of GEIs can promote survival of pathogenic as well as environmental bacteria.
Identification of different roles for RanGDP and RanGTP in nuclear protein import.

The importin‐alpha/beta heterodimer and the GTPase Ran play key roles in nuclear protein import. Importin binds the nuclear localization signal (NLS). Translocation of the resulting import ligand complex through the nuclear pore complex (NPC) requires Ran and is terminated at the nucleoplasmic side by its disassembly. The principal GTP exchange factor for Ran is the nuclear protein RCC1, whereas the major RanGAP is cytoplasmic, predicting that nuclear Ran is mainly in the GTP form and cytoplasmic Ran is in the GDP‐bound form. Here, we show that nuclear import depends on cytoplasmic RanGDP and free GTP, and that RanGDP binds to the NPC. Therefore, import might involve nucleotide exchange and GTP hydrolysis on NPC‐bound Ran. RanGDP binding to the NPC is not mediated by the Ran binding sites of importin‐beta, suggesting that translocation is not driven from these sites. Consistently, a mutant importin‐beta deficient in Ran binding can deliver its cargo up to the nucleoplasmic side of the NPC. However, the mutant is unable to release the import substrate into the nucleoplasm. Thus, binding of nucleoplasmic RanGTP to importin‐beta probably triggers termination, i.e. the dissociation of importin‐alpha from importin‐beta and the subsequent release of the import substrate into the nucleoplasm.
Half-Duplex Estimate-and-Forward Relaying : Achievable Rates and Code Design

We propose a practical coding scheme for halfduplex estimate-and-forward relaying. The proposed const ruction is guided by the information theoretic coding scheme for the estimate-and-forward relay protocol. Our construction incorporates several design features to reduce receiver complex ity without compromising performance. Observing that the relaying gain is significant only at low SNRs, we use binary LDPC codes i n the source broadcast phase of relaying. Estimation is perfo rmed by entropy constrained scalar quantization of the receivedsignal at the relay. Finally, a procedure similar to maximal ratio combining is used to aggregate direct and relayed signals at the destination. An important practical advantage of our scheme is that it does not require source-relay symbol synchronizati on. The codes outperform direct and two-hop channel capacities, as well as decode-and-forward relaying when the relay-destinatio n link is strong.
Assessment of 3D Viewers for the Display of Interactive Documents in the Learning of Graphic Engineering

The purpose of this study is to determine which 3D viewers should be used for the display of interactive graphic engineering documents, so that the visualization and manipulation of 3D models provide useful support to students of industrial engineering (mechanical, organizational, electronic engineering, etc). The technical features of 26 3D visualization software programmes (viewers, publishers, 3D output formats) are examined, to select the three visualization configurations that best meet our needs at the Graphic Expression Department of the University of Burgos (Solidworks plus Solidworks eDrawings; Catia plus Catia eDrawings and 3DXML; several Computer-Aided Design software programmes plus Adobe Acrobat Pro Extended). These are compared using the Quality Function Deployment tool known as House of Quality. The House of Quality has enabled us to identify and quantify the importance attached by engineering teachers to each of their requirements for 3D viewers, and to identify and quantify the technical importance of each of the measurable features of these viewers.
Distance-Dependent Scaling of AMPARs Is Cell-Autonomous and GluA2 Dependent

The extensive dendritic arbor of a pyramidal cell introduces considerable complexity to the integration of synaptic potentials. Propagation of dendritic potentials is largely passive, in contrast to regenerative axonal potentials that are maintained by voltage-gated sodium channels, leading to a declination in amplitude as dendritic potentials travel toward the soma in a manner that disproportionally affects distal synaptic inputs. To counteract this amplitude filtering, Schaffer collateral synapses onto CA1 pyramidal cells contain a varying number of AMPA receptors (AMPARs) per synapse that increases with distance from the soma, a phenomenon known as distance-dependent scaling. Here, we undertake an investigation into the molecular mechanisms of distance-dependent scaling. Using dendritic recordings from rat pyramidal neurons, we confirm the basic scaling phenomenon and find that it is expressed and can be manipulated cell autonomously. Finally, we show that it depends on the presence of both a reserve pool of AMPARs and the AMPAR subunit GluA2.
Energy-Efficient Multichannel MAC Protocol Design for Bursty Data Traffic in Underwater Sensor Networks

How to reduce power consumption is a critical issue in underwater sensor networks (UWSNs) since sensor nodes have limited energy resource. Utilizing multiple channels and duty cycling may help conserve energy because transmission collisions and idle listening can be reduced. Bursty traffic is common in UWSN; however, we do not find satisfactory solutions that can deliver this type of traffic efficiently in a duty-cycled environment. In this paper, we propose a dynamic duty-cycled multiple-rendezvous multichannel medium access control (DMM-MAC) protocol that is suitable for transmitting bursty traffic in a duty-cycled UWSN. Built on top of multiple-rendezvous multichannel MAC (MM-MAC), a node running DMM-MAC needs only one modem. DMM-MAC can operate in a more realistic multihop environment, instead of a simplified single-hop network, without the information of relative distances or propagation delays to other nodes. Utilizing the proposed dynamic duty cycling mechanism, nodes running DMM-MAC can deliver bursty traffic efficiently. Simulation results verify that DMM-MAC conserves energy and enhances network performance when compared to MM-MAC.

Born with a silver spoon: Danish evidence on intergenerational wealth formation from cradle to adulthood1

Using longitudinal data on wealth holdings of parents and children in Denmark, we show the intergenerational rank correlation of wealth develops at early age of the child and reaches its long-term value of about 0.25 by the time children are in their teens. While assets owned by children at that point of the life-cycle are naturally small, asset-holdings at age 18 are already more informative than parental wealth in predicting wealth holdings of children many years later when they are in their 40s, especially for families at the top of the wealth distribution, where childhood asset ownership is widespread. This indicates that parental behavior early on is a critical factor for the development of intergenerational wealth correlation and goes beyond previously studied channels, such as correlation of earnings and saving in adulthood, or transfers late in life and at death.
Earnings, Adaptation, and Equity Value

This paper develops a model in which earnings and book value are complementary factors in determining equity value. Current earnings relative to book value provides information about how well the firm is currently using its resources. When current earnings to book value is high, the firm is likely to continue its current way of employing resources and earnings is the more important determinant of equity value. When current earnings to book value is low, the firm is more likely to adapt its resources to a superior alternative use, and book value becomes the more important determinant of equity value because book value provides a measure of the value of the firm's resources, independent of how well the resources are currently utilized. The model leads to two main empirical predictions: First, equity value is a convex function of expected earnings and book value. Second, the change in equity value associated with changes in expected earnings increases with the relative level of earnings to book value. Evidence from a variety of specifications is consistent with predictions. Thus, the results imply that equity value is a function of both expected earnings and book value (in contrast to models which incorporate one or the other) and that the form of the function is convex (in contrast to models which assume the two elements of value are simply additive).
Estimation of Apartment Submarkets in Dublin, Ireland

This study compares apartment submarkets within a major European city. The price behavior of the Dublin, Ireland apartment market is tested using hedonic models and aggregate and disaggregate data. The results strongly indicate that the modeling of apartment markets at the disaggregate level does result in significant improvements in comparison to estimations undertaken at an aggregate level. This particular apartment market is especially interesting, due to the introduction of fiscal incentives. To fully understand the Dublin apartment market requires an appreciation of the role played by tax breaks for owner-occupiers and investors in urban renewal locations. The results show that different submarkets responded differently.
The Intergenerational Transmission of Empathy-Related Responding in Adolescence: The Role of Maternal Support

This study proposed and tested an integrated model of the intergenerational transmission of empathy-related responding in adolescence. This model included maternal support as a mediator of the intergenerational transmission of empathy and examined friendship quality as an outcome of adolescent empathy. In a sample of middle adolescents and their mothers (N = 177), maternal support significantly predicted the empathy dimensions perspective taking and sympathy and mediated the mother–child concordance of perspective taking but not sympathy. Adolescent empathy (and perspective taking in particular) predicted adolescent friendship quality and served as an intervening variable in the relation between maternal support and friendship quality. Implications of the present study for research on the socialization of empathy-related responding and social adjustment in general are outlined.
Connecting Principal Succession and Professional Learning

The purpose of this qualitative study was to explore the connections between principal succession and professional learning through the analysis of the current practices in leader development, support, and retention in two Georgia state school districts. The findings of the cross-case analysis were summarized in five major themes: First, a key component to the overall success of principal professional learning and succession is a visionary superintendent. Second, planning for principal succession, school districts strongly favor local applicants. Third, building leaders from within the district is an effective way to ensure leader continuity. Fourth, developing future principals, school districts express strong preference for the nonuniversity leader preparation programs, designed to address their specific needs. Finally, leader professional development and succession are tightly connected. Implications for research and practice are offered.
PROT — An embodied agent for intelligible and user-friendly human-robot interaction

A system has been developed that can project an embodied agent's image and sound anywhere in a room. It can thus overcome the problems inherent to other embodied agents in dealing with 2D on-screen information and 3D physical information simultaneously. An experiment demonstrated that this ‘PROT’ agent can effectively present both on-screen information and real-world physical information. Because the PROT agent combines the advantages of a robot agent with those of an on-screen agent, it should improve human-robot interaction.
Paying attention to speaking rate

Variability in speaking rate results in a many-to-many mapping between acoustic properties in speech and the linguistic interpretation of an utterance. In order to recognize the phonetic structure of an utterance, listeners must calibrate their phonetic decisions against the rate at which the speech was produced. This process of rate normalization is fast and effective allowing listeners to maintain phonetic constancy in spite of changes in speaking rate. Most of the research on rate normalization has investigated the sources of information used by listeners to determine the speaking rate. There is an assumption in much of this research that the normalization process is a passive, automatized filtering process that strips the effects of rate variation away from the signal prior to recognition. The study starts from a different perspective by assuming that speech perception is carried out by an active perceptual process that is specifically needed to address the lack of invariance problem (Nusbaum and Henly). This perspective predicts that increased variability from any source, including rate variability, should increase the cognitive load during speech perception. The results support this prediction.
Polycystic Kidney Disease , Autosomal Dominant Synonym : ADPKD

Autosomal dominant polycystic kidney disease (ADPKD) is generally a late-onset multisystem disorder characterized by: bilateral renal cysts; cysts in other organs including the liver, seminal vesicles, pancreas, and arachnoid membrane; vascular abnormalities including intracranial aneurysms, dilatation of the aortic root, and dissection of the thoracic aorta; mitral valve prolapse; and abdominal wall hernias. Renal manifestations include hypertension, renal pain, and renal insufficiency. Approximately 50% of individuals with ADPKD have endstage renal disease (ESRD) by age 60 years. The prevalence of liver cysts, the most common extrarenal manifestation of ADPKD, increases with age and may have been underestimated by ultrasound studies. The prevalence of intracranial aneurysms is higher in those with a positive family history of aneurysms or subarachnoid hemorrhage (22%) than in those without such a family history (6%). Mitral valve prolapse, the most common valvular abnormality, occurs in up to 25% of affected individuals. Substantial variability in severity of renal disease and other extrarenal manifestations occurs even within the same family.
Teaching Experiences of African American Educators in the Rural South

A scarcity of research exists regarding the voices of African American teachers who taught in the rural South. In this study, we report the life experiences, perceptions, thoughts, and feelings of three female African American educators as they pertain to their experiences teaching before, during, and after desegregation. Three female African American educators who taught before, during, and after desegregation in the same school district in the rural South were interviewed extensively. Data analysis revealed themes that mirrored those themes found in resiliency research. By examining these resilience themes within the context of this study, a model of adult resilience in teaching emerged. Key Words: Resilience, African American, Teachers, and Desegregation

The stylised facts in this debate seem to be: globalisation introduces more volatility in labour markets, with more entries and exits of both firms and workers and therefore the capacity to constantly adjust – again both for firms and workers – becomes crucial. " Rigid " labour market institutions thus become a binding constraint, as they are assumed to hinder efficient adjustment, resulting in productivity losses and inefficient (reallocation n of labour on labour markets. In addition, generous social security benefits would equally hinder quick adjustment, because of the work disincentive that is part of such schemes. However, this view, which blames an important part of worker's security for exacerbating labour market and economic problems, is not shared by everyone and the debate on labour market institutions continues unabated: on the one hand ever more sophisticated econometric models are used to suggest that at their present levels, labour market institutions cause distortions in labour markets and are thus responsible for unemployment, low employment levels, informality and …
