Fostering ambiguity: decontextualizing and repurposing a familiar public display

Innovations in HCI tend to rely on exploring new technologies and novel forms of interaction. For decades artists such as Jenny Holzer have sought to provoke the public with art installations by repurposing public displays and exploring ambiguous messaging. Gaver argues that ambiguity can be intriguing, mysterious, and delightful, something that engages users and allows them to explore, discover, and interpret situations for themselves. In this paper we describe MStoryG, a public digital art installation that employs a decontextualized and repurposed airport split-flap display to support collaborative storytelling. In order to explore whether ambiguity attracts the glances of passersby and through curiosity invites interaction we devised a high fidelity software prototype that facilitated rapid deployment of experiments at two different locations. In addition to evaluating user engagement with the installation we define guidelines for others seeking to repurpose familiar objects in order to attract and engage passersby.
Localized Movement-Assisted SensorDeployment Algorithm for HoleDetection and Healing

One of the fundamental services provided by a wireless sensor network (WSN) is the monitoring of a specified region of interest (RoI). Considering the fact that emergence of holes in the RoI is unavoidable due to the inner nature of WSNs, random deployment, environmental factors, and external attacks, assuring that the RoI is completely and continuously covered is very important. This paper seeks to address the problem of hole detection and healing in mobile WSNs. We discuss the main drawbacks of existing solutions and we identify four key elements that are critical for ensuring effective coverage in mobile WSNs: 1) determining the boundary of the RoI, 2) detecting coverage holes and estimating their characteristics, 3) determining the best target locations to relocate mobile nodes to repair holes, and 4) dispatching mobile nodes to the target locations while minimizing the moving and messaging cost. We propose a lightweight and comprehensive solution, called holes detection and healing (HEAL), that addresses all of the aforementioned aspects. The computation complexity of HEAL is O(v2) , where v is the average number of 1-hop neighbors. HEAL is a distributed and localized algorithm that operates in two distinct phases. The first identifies the boundary nodes and discovers holes using a lightweight localized protocol over the Gabriel graph of the network. The second treats the hole healing, with novel concept, hole healing area. We propose a distributed virtual forces-based local healing approach where only the nodes located at an appropriate distance from the hole will be involved in the healing process. Through extensive simulations we show that HEAL deals with holes of various forms and sizes, and provides a cost-effective and an accurate solution for hole detection and healing.
The Effect of Providing Breakfast in Class on Student Performance.

Many schools have recently experimented with moving breakfast from the cafeteria to the classroom. We examine whether such a program increases achievement, grades, and attendance rates. We exploit quasi‐random timing of program implementation that allows for a difference‐in‐differences identification strategy. We find that providing breakfast in class relative to the cafeteria raises math and reading achievement by 0.09 and 0.06 standard deviations, respectively. These effects are most pronounced for low‐performing, free lunch‐eligible, Hispanic, and low body mass index students. A lack of differences by exposure time and effects on grades suggest that these impacts are on test‐taking performance rather than learning. At the same time, the results highlight the possibility that measured achievement may be biased downwards, and accountability penalties may be inappropriately applied, in schools where many students do not consume breakfast.
Sustainability of Free/Libre Open Source Projects: A Longitudinal Study

This paper examines the factors that influence the long-term sustainability of FLOSS projects. A model of project sustainability based on organizational ecology is developed and tested empirically. Data about activity and contribution patterns over the course of five years for 2,772 projects registered with SourceForge is analyzed. Our results suggest that the size of the project’s development base, project age and the size of niche occupied by the project are positively related to the project’s ability to attract user and/or developer resources. The ability to attract resources is an indicator of the perceived project legitimacy, which in turn is a strong predictor of the project’s future sustainability. Thus a project’s ability to attract developer and user resources is shown to play a mediating role between the demographic (size and age) and ecological (niche) characteristics of the project and its future sustainability. Our results support the applicability of tenets of organizational ecology related to the liability of smallness, the liability of newness, and population characteristics (niche size) to the FLOSS development environment. The implications of the results for future research and practice are discussed.
Value Versus Growth: Australian Evidence

Fama and French (1992) and Lakonishok, Shleifer and Vishny (1994) show that value stocks earn substantially higher returns than growth stocks. Barbee, Mukherji and Raines (1996) and Leledakis and Davidson (2001) show that the ratio of sales-to-price and debt-to-equity are better predictors of average equity returns than book-to-market equity and firm size. In this paper, we evaluate the ability of size, book-to-market, sales-to-price, cash flow-to-price, earnings-to-price and debt-to-equity in explaining the cross-sectional variation in equity returns. Our findings show that sales-to-price, earnings-to-price and cash flow-to-price are highly significant in explaining cross-sectional variation in equity returns. However, book-to-market emerges as the best predictor of average equity returns, displaying the highest level of significance in joint regressions. In summary, we document that book-to-market is the best predictor of equity returns in Australia and thus is the best proxy for value/glamour.
Do degree adverbs guide adjective learning crosslinguistically? A comparison of Dutch and Russian

Abstract A fundamental question in language acquisition research is how language-specific input interacts with (pre-linguistic) universal concepts. In order to shed more light on this issue, the present paper reports the results of two experiments, set up as a modified version of Syrett, Kristen & Jeffrey Lidz. 2010. 30-month-olds use the distribution and meaning of adverbs to interpret novel adjectives. Language Learning and Development 6(4). 258–282. Their study has revealed that English-speaking 30-month-olds use degree adverbs for interpreting novel adjectives; the participants were more likely to assign a relative meaning (e.g., tallness) to a novel adjective if the adjective was modified by the booster very and to select an absolute interpretation (e.g., straightness) if the adjective was preceded the maximizer completely. The distribution in Dutch, although typologically similar to English, is obscured by phonological, morphological and semantic factors, which makes the Dutch degree adverbs heel ‘very’ and helemaal ‘completely’ less reliable cues to a language learner. In Russian, the booster očen’ ‘very’ is a reliable cue and the maximizer sovsem ‘completely’ is not, since it can be used with both absolute and negative-pole relative adjectives. The results demonstrate that children’s performance is related to the reliability of cues in their input. Russian-speaking toddlers only relied on the booster očen’, but not on the maximizer sovsem for assigning novel adjectives to semantic classes, and their Dutch-speaking peers did not show evidence of using degree adverbs for adjective learning at all. No evidence of interfering universal predispositions was found.
Analysis of translation using polysome profiling

Abstract During the past decade, there has been growing interest in the role of translational regulation of gene expression in many organisms. Polysome profiling has been developed to infer the translational status of a specific mRNA species or to analyze the translatome, i.e. the subset of mRNAs actively translated in a cell. Polysome profiling is especially suitable for emergent model organisms for which genomic data are limited. In this paper, we describe an optimized protocol for the purification of sea urchin polysomes and highlight the critical steps involved in polysome purification. We applied this protocol to obtain experimental results on translational regulation of mRNAs following fertilization. Our protocol should prove useful for integrating the study of the role of translational regulation in gene regulatory networks in any biological model. In addition, we demonstrate how to carry out high-throughput processing of polysome gradient fractions, for the simultaneous screening of multiple biological conditions and large-scale preparation of samples for next-generation sequencing.
Perceived Prosodic Boundaries and Their Phonetic Correlates

This paper addresses two main questions: (a) Can listeners assign values of perceived boundary strength to the juncture between any two words? (b) If so, what is the relationship between these values and various (combinations of) suprasegmental features. Three speakers read a set of twenty utterances of varying length and complexity. A panel of nineteen listeners assigned boundary strength values to each of the 175 word boundaries in the material. Then the correlation was established between the variable strength of the perceived boundaries and three prosodic variables: melodic discontinuity, declination reset and pause. The results show that speakers may differ in their strategies of prosodic boundary marking and listeners agree in the perceptual weight they attribute to the prosodic cues.
Multiple Meanings of Calling: Next Steps for Studying an Evolving Construct

Research on work as a calling has rapidly increased in recent years, yet the lack of consensus regarding the construct’s definition presents key challenges to researchers, most notably the potential lack of coherence as research on calling accumulates. We begin with a brief overview of current definitions in the literature to illustrate the overlapping yet distinct conceptualizations of the construct, placing them along a continuum of “neoclassical” to “modern. ” Next, we explore strengths and shortcomings of the two most commonly employed methodological strategies for studying calling, the “top-down” and “bottom-up” approaches. We invite researchers to adopt a third strategy, the typological approach (and the taxometric method in particular), to offer much-needed conceptual clarity by empirically investigating whether there are distinct types of calling or whether the construct is best conceptualized as dimensional in nature. Finally, we present recommendations to guide researchers, reviewers, and consumers of research related to work as a calling on a path that reduces its ongoing conceptual murkiness.
Study in System-Based Analysis : The ThreeBallot Voting System and Prêt à Voter

Threat analysis of voting systems is an increasing field of interest. While it is important to verify the system itself, it has been found that certain vulnerabilities only become apparent when taking a “system-based” view, i.e. considering interactions between the various components of a scheme. In this paper we apply a model for systembased analysis [22] to carry out a systematic threat analysis of the ThreeBallot voting system [18] and Prêt à Voter [8].
Indian Ocean circulation and climate variability

In recent years, the Indian Ocean (IO) has been discovered to have a much larger impact on climate variability than previously thought. This paper reviews climate phenomena and processes in which the IO is, or appears to be, actively involved. We begin with an update of the IO mean circulation and monsoon system. It is followed by reviews of ocean/atmosphere phenomenon at intraseasonal, interannual, and longer time scales. Much of our review addresses the two important types of interannual variability in the IO, El Niño–Southern Oscillation (ENSO) and the recently identified Indian Ocean Dipole (IOD). IOD events are often triggered by ENSO but can also occur independently, subject to eastern tropical preconditioning. Over the past decades, IO sea surface temperatures and heat content have been increasing, and model studies suggest significant roles of decadal trends in both the Walker circulation and the Southern Annular Mode. Prediction of IO climate variability is still at the experimental stage, with varied success. Essential requirements for better predictions are improved models and enhanced observations.
Trading the Bond-CDS Basis-The Role of Credit Risk and Liquidity

We analyze trading opportunities that arise from differences between the bond and the CDS market. By simultaneously entering a position in a CDS contract and the underlying bond, traders can build a default-risk free position that allows them to repeatedly earn the difference between the bond asset swap spread and the CDS, known as the basis. We show that the basis size is closely related to measures of company-specific credit risk and liquidity, and to market conditions. In analyzing the aggregate profits of these basis trading strategies, we document that dissolving a position leads to significant profit variations, but that attractive risk-return characteristics still apply. The aggregate profits depend on the credit risk, liquidity, and market measures even more strongly than the basis itself, and we show which conditions make long and short basis trades more profitable. Finally, we document the impact of the financial crisis on the profits of long and short basis trades, and show that the formerly more profitable long basis trades experienced more drastic profit decreases than short basis trades.

Ocean turbulence at meso and submesoscales: connection between surface and interior dynamics

High resolution simulations of ocean turbulence with Rossby number of order one have revealed that upper layer dynamics significantly differs from the interior dynamics. As reported before, upper layer dynamics is characterized with shallow velocity spectrum corresponding to kinetic energy distributed over a spectral range from mesoscales to small scales. This dynamics is driven by small-scale frontogenesis related to surface density anomalies. Interior dynamics is characterized by steeper velocity spectrum and is driven by the potential vorticity anomalies set up by the interior baroclinic instability. Impact of the divergent motions related to surface frontogenesis leads to a warming of the upper layers, a cyclone dominance and a negative skewness of the isopycnal displacements. On the contrary, divergent motions in the interior lead to a cooling of the deeper layers, an anticylone dominance and a positive skewness of the isopycnal displacements. These different ageostrophic processes are consistent with an SQG regime extended to Rossby number of order one on one hand and an interior QG regime extended to Rossby number of order one on the other hand, as proposed by previous studies. Synthesis of these characteristics suggest a connection between upper and deeper layers, induced by the divergent motions, through which small scales near the surface interact with mesoscales in the interior.
3 A . 1 OBSERVATIONS AND MODELING OF STRUCTURAL-OPTICAL PROPERTIES IN FIRST-YEAR SEA ICE

An understanding of radiative transfer in sea ice is critical to understanding the heat and mass balance of the Arctic. Radiative transfer affects such processes as surface melting, ice-albedo feedback, solar heating of the upper ocean, and internal heat storage within the ice. Large temporal changes in the physical state of the ice cover cause large changes in its radiative properties, particularly during the summer. As the surface warms, melts, and forms ponds, there is a substantial decrease in its albedo. To better model changes in the physical state of the ice and its ability to backscatter light, we need a more complete understanding of its fundamental optical properties. Sea ice is a lattice of nearly pure ice with embedded inclusions of brine, vapor, precipitated salts, and occasional particulate material. The optical properties are determined not only by the bulk volumes of these constituents and their dielectric properties, but also by the inclusion distributions. While numerous studies have been done on the structural properties of sea ice (e.g. Weeks and Ackley, 1981; Perovich and Gow, 1991, 1996), and its optical properties (see Perovich, 1996), relationships between the two have not yet been firmly established. Because changes in temperature cause the relative amounts of ice, brine, vapor, and precipitated salt to adjust according to freezing equilibrium relationships (Cox and Weeks, 1983), we expect the optical properties of ice to also depend on temperature. The focus of this work is to improve our understanding of how temperature-dependent changes in microstructure govern the inherent optical properties of first-year sea ice.
The Consequences of Collective Discontent: A New Measure of Zeitgeist Predicts Voting for Extreme Parties

In recent years, extreme right-wing and left-wing political parties and actors have gained popularity in many Western countries. What motivates people to vote for extreme right- or left-wing parties? In previous research, we showed that a collectively shared sense of doom and gloom about society can exist among citizens who, individually, experience high well-being. Previous research developed an operationalization of this collective societal discontent as an aspect of Zeitgeist, which can be compared to personal experiences (van der Bles, Postmes, & Meijer, 2015). In the present research, we investigated whether this Zeitgeist of societal discontent predicts voting for extreme parties. We conducted a field study during the 2015 Dutch provincial elections (N = 407). Results showed that collective societal discontent (Zeitgeist) predicted voting for extreme parties but that personal discontent did not. Results also showed that pessimistic Zeitgeist was associated with lower education levels and tabloid-style media consumption. These findings advance our understanding of the discontents that fuel extreme voting outcomes: Global and abstract (negative) beliefs about society are more consequential than concrete personal experiences.
Poisson deformations of affine symplectic varieties

This is a continuation of math.AG/0609741. Let Y be an affine symplectic variety with a C^*-action with positive weights, and let \pi: X -> Y be its crepant resolution. Then \pi induces a natural map PDef(X) -> PDef(Y) of Kuranishi spaces for the Poisson deformations of X and Y. In the Part I, we proved that PDef(X) and PDef(Y) are both non-singular, and this map is a finite surjective map. In this paper (Part II), we prove that it is a Galois covering. Markman already obtained a similar result in the compact case, which was a motivation of this paper. As an application, we shall construct explicitly the universal Poisson deformation of the normalization \tilde{O} of a nilpotent orbit closure \bar{O} in a complex simple Lie algebra when \tilde{O} has a crepant resolution.
Marriage Family Therapist’s Attitudes Toward Evidence-Based Treatments and Readiness for Change

As the major implementation of the affordable Care Act of 2010 becomes reality in 2014, demands placed on mental health providers to utilize evidence-based treatments (EBTs) with clients has become a more relevant issue for practitioners. Little is known about the factors that affect Marriage and Family Therapists (MFTs) from implementing EBTs. To fill the gap in understanding these therapists’ attitudes toward effective change and implementation of EBTs is the goal of the study. MFT attitudes toward adopting EBTs and their readiness for change in their treatment practices are examined. Participants were 137 Licensed MFTs providing mental health services in California. t tests, correlation analyses, and multiple regressions illustrated that gender, education, previous study of EBTs, and utilization of previous training were associated with more positive attitudes toward adoption of EBT. Mental health organizations and policymakers may benefit from consideration of how MFT’s training is associated with their attitude toward change in practice. Las actitudes de terapeutas de matrimonio y familia hacia tratamientos basados en evidencia y preparación para el cambio Como la principal aplicación del Affordable Care Act del 2010 se hace realidad en 2014, demandas hechas en los proveedores de salud mental a utilizar tratamientos basados en evidencia (EBT por sus siglas en inglés) con clientes se ha hecho un problema más relevante a los practicantes. Poco se sabe de los factores que afectan terapeutas de matrimonio y familias (MFT por sus siglas en ingles) de implementando EBTs. Para llenar el vacío de información en entender los actitudes de estos terapeutas hacia un cambio efectivo e implementación de EBTs es el objetivo de este artículo. Los actitudes de MFT hacia adoptando EBTs y sus preparación por cambio en su práctica de tratamiento son examinados. Participantes fueron 137 licenciado MFTs prestaban servicios en California. Pruebas t, análisis de correlación, y regresión múltiple ilustraron que sexo, educación, estudio previo de EBTs, y utilización de practica previo fueron asociados con más actitudes positivos hacia adopción al EBT. Organizaciones de salud mental y políticos pueden beneficiar de las consideraciones de como la formación de MFTs es asociado con sus actitudes hacia el cambio en la práctica.

A Systematic Literature Review on relationship between agile methods and Open Source Software Development methodology

Agile software development methods (ASD) and open source software development methods (OSSD) are two different approaches which were introduced in last decade and both of them have their fanatical advocators. Yet, it seems that relation and interface between ASD and OSSD is a fertile area and few rigorous studies have been done in this matter. Major goal of this study was assessment of the relation and integration of ASD and OSSD. Analyzing of collected data shows that ASD and OSSD are able to support each other. Some practices in one of them are useful in the other. Another finding is that however there are some case studies using ASD and OSSD simultaneously, but there is not enough evidence about comprehensive integration of them.
