Telling a “baby story”: Mothers narrating their pre-schoolers' past across two cultural contexts

Mothers from two middle-class contexts from Berlin, Germany (n = 35), and Delhi, India (n = 28) told a baby story to their 3-year olds about an event that had happened during the children's first year of life. The contexts represented two cultural models: the model of psychological autonomy (Berlin) and the model of autonomy-relatedness (Delhi). We investigated the culture-specific functions of this reminiscing task as reflected in the structure, content and specificity of the stories. The stories in both contexts were minimally interactive and the children contributed few elaborations themselves. Stories told by the Berlin mothers were longer, and more specific. Mothers in both contexts were similarly elaborative relative to being repetitive. The stories were highly child-centred in both contexts but even more child-centred for Delhi. Importantly, maternal narrations from the Berlin context were embedded in a frame story that characterised the child's individual past; stories thus constructed “exclusive baby stories”. Most stories told by the Delhi mothers had no frame story but instead were about what the child used to do as a baby in general; they thus constructed “routine baby stories”. Results are interpreted in the view of the underlying self, social and directive functions of this reminiscing task.
Manila to Malaysia, Quezon to Qatar

I estimate the effect of international migration on the human capital of children in the migrants’ origin country. Using administrative data containing all migrant departures from the Philippines, I exploit variation across provinces in destination-country demand for migrants. My estimates are at the local labor market level, allowing for spillovers to nonmigrant households. An average year-to-year percent increase in migration causes a 3.5 percent increase in secondary school enrollment. The effects are likely driven by increased income rather than an increased expected wage premium for education.
Cleansing Test Suites from Coincidental Correctness to Enhance Fault-Localization

Researchers have argued that for failure to be observed the following three conditions must be met: 1) the defect is executed, 2) the program has transitioned into an infectious state, and 3) the infection has propagated to the output. Coincidental correctness arises when the program produces the correct output, while conditions 1) and 2) are met but not 3). In previous work, we showed that coincidental correctness is prevalent and demonstrated that it is a safety reducing factor for coverage-based fault localization. This work aims at cleansing test suites from coincidental correctness to enhance fault localization. Specifically, given a test suite in which each test has been classified as failing or passing, we present three variations of a technique that identify the subset of passing tests that are likely to be coincidentally correct. We evaluated the effectiveness of our techniques by empirically quantifying the following: 1) how accurately did they identify the coincidentally correct tests, 2) how much did they improve the effectiveness of coverage-based fault localization, and 3) how much did coverage decrease as a result of applying them. Using our better performing technique and configuration, the safety and precision of fault-localization was improved for 88% and 61% of the programs, respectively.
Studying the X-ray hysteresis in GX 339−4: the disc and iron line over one decade

We report on a comprehensive and consistent investigation into the X-ray emission from GX 339−4. All public observations in the 11 year RXTE archive were analysed. Three different types of model ‐ single power law, broken power law and a disc + power law ‐ were fitted to investigate the evolution of the disc, along with a fixed Gaussian component at 6.4 keV to investigate any iron line in the spectrum. We show that the relative variation in flux and X-ray colour between the two best sampled outbursts are very similar. The decay of the disc temperature during the outburst is clearly seen in the soft state. The expected decay is SDisc ∝ T 4 ; we measure T 4.75±0.23 . This implies that the inner disc radius is approximately constant in the soft state. We also show a significant anticorrelation between the iron line equivalent width (EW) and the X-ray flux in the soft state while in the hard state the EW is independent of the flux. This results in hysteresis in the relation between X-ray flux and both line flux and EW. To compare the X-ray binary outburst to the behaviour seen in active galactic nuclei (AGN), we construct a disc fraction luminosity diagram for GX 339−4, the first for an X-ray binary. The shape qualitatively matches that produced for AGN. Linking this with the radio emission from GX 339−4 the change in radio spectrum between the disc and power-law-dominated states is clearly visible.
Revealing Privacy-Impacting Behavior Patterns of Smartphone Applications

Smartphone application usage impacts users’ privacy. However, due to the lack of an appropriate level of insight into sensitive information processing, users are not in the position to assess the extent of impact. In this paper, we propose an information-flow monitoring and privacy awareness-raising system that provides users with comprehensible information on how their privacy is impacted by long-term application usage. We further introduce and utilize privacy-impacting behavior patterns as a novel concept to detect particular privacyaffecting activities of smartphone applications. Keywords-smartphone privacy; notice; awareness; information flow
A reinforcement learning approach towards autonomous suspended load manipulation using aerial robots

In this paper, we present a problem where a suspended load, carried by a rotorcraft aerial robot, performs trajectory tracking. We want to accomplish this by specifying the reference trajectory for the suspended load only. The aerial robot needs to discover/learn its own trajectory which ensures that the suspended load tracks the reference trajectory. As a solution, we propose a method based on least-square policy iteration (LSPI) which is a type of reinforcement learning algorithm. The proposed method is verified through simulation and experiments.
Layer-2 security for PLC - a comparison between ITU-T G.9903 and IEEE 1901.2

This paper describes the layer-2-security functions of two narrow-band power line communication standards, namely ITU-T G.9903 and IEEE 1901.2. We describe how access control, authentication, confidentiality and integrity for network devices are achieved in both standards. We compare the approaches by using two practice-oriented installation scenarios and by evaluating the security methods.
Does Fear of Isolation Disappear Online? Attention-Seeking Motivators in Online Political Engagement

This study investigated the effects of fear of isolation (FOI) on political content consumption and creation in the context of online communication. Using more than 1,000 respondents from South Korea, the study empirically tested a theoretical model of FOI on political content consumption and expressions with two mediators (i.e., attention/status-seeking, and anonymity-seeking). Results indicated that FOI is related to seeking attention and status in political outlets also connected to anonymity-preference that leads to political expression. Implications for political communication scholarship and for practitioners are that voters’ political participations can be understood in a framework different from traditional focus on persuasion, political ideology, or demographics because—in today’s virtual and interactive media environment—users are more content consumers or community participants.
Impact of hydrological variations on modeling of peatland CO2 fluxes: Results from the North American Carbon Program site synthesis

[1] Northern peatlands are likely to be important in future carbon cycle-climate feedbacks due to their large carbon pools and vulnerability to hydrological change. Use of non-peatland-specific models could lead to bias in modeling studies of peatland-rich regions. Here, seven ecosystem models were used to simulate CO2fluxes at three wetland sites in Canada and the northern United States, including two nutrient-rich fens and one nutrient-poor,sphagnum-dominated bog, over periods between 1999 and 2007. Models consistently overestimated mean annual gross ecosystem production (GEP) and ecosystem respiration (ER) at all three sites. Monthly flux residuals (simulated – observed) were correlated with measured water table for GEP and ER at the two fen sites, but were not consistently correlated with water table at the bog site. Models that inhibited soil respiration under saturated conditions had less mean bias than models that did not. Modeled diurnal cycles agreed well with eddy covariance measurements at fen sites, but overestimated fluxes at the bog site. Eddy covariance GEP and ER at fens were higher during dry periods than during wet periods, while models predicted either the opposite relationship or no significant difference. At the bog site, eddy covariance GEP did not depend on water table, while simulated GEP was higher during wet periods. Carbon cycle modeling in peatland-rich regions could be improved by incorporating wetland-specific hydrology and by inhibiting GEP and ER under saturated conditions. Bogs and fens likely require distinct plant and soil parameterizations in ecosystem models due to differences in nutrients, peat properties, and plant communities.
Adolescent's physical activity levels and relatives' physical activity engagement and encouragement: the HELENA study.

BACKGROUND The aim of this article is to examine the association between adolescents' physical activity (PA) levels and their relatives' (father, mother, brothers, sisters and best friend) PA engagement and encouragement. METHODS Adolescents (52.3% girls) aged 12.5-17.5 years were gathered from the HELENA study. Adolescents' PA levels were assessed by the International Physical Activity Questionnaire for Adolescents (valid data on 3007 participants) and accelerometry (valid data on 2200 participants). Relatives' engagement and encouragement were reported by the adolescents and encoded into three categories (low, middle and high). RESULTS Analysis of covariance showed that relatives' PA encouragement was more strongly associated with adolescents' PA levels than relatives' PA engagement. Pairwise comparisons indicated that the higher the encouragement level (from most relatives) the higher the adolescent's PA levels. This finding was overall consistent when using self-report or objective methods for assessing adolescents' PA levels, yet the associations were stronger when using self-report methods. CONCLUSIONS These findings highlight the important role of social encouragement on adolescents' PA levels. Community interventions aiming to enhance PA levels in the adolescent population might be more successful when family and peers are also targeted.
Traffic characterization for flexible service delivery in next-generation converged access networks

— The evolution towards converged access networks and the importance of quality of experience at an affordable cost brings the need for access networks that can offer a wide range of services not currently available to the desired extent. Legacy networks used explicit signaling that traversed all nodes along the path to book resources before the launch of the media stream. This approach does not scale and cannot provide adequate resource control and Service Level Agreement (SLA) management in scalable and autonomous packet networks. Still, the need to reserve resources in advance remains since real-time services have limited, if any, means of adjusting their rates to the prevailing network conditions. Hence, in order to preserve customer satisfaction, the traditional preventive approach that reserves resources for the duration of the session is the only option. This paper proposes a measurement based approach to derive the flow resource needs and then trigger the Resource and Admission Control enriching the network with implicit admission control. We evaluate the proposed methodology against other approaches that employ measurement based Effective Bandwidth estimation and demonstrate its noticeable performance in terms of achievable resource utilisation, accuracy and practical feasibility
Teacher Leadership in Professional Development Schools: Emerging Conceptions, Identities, and Practices

This is a study of emerging teacher leadership in professional development schools. Twelve teachers describe how they reconceptualized leadership as they gained new experiences, confidence, and shifted their identities as teachers by working with colleagues within the school and in the university. These emerging leaders assumed responsibilities for school change and evoked leadership in others. They learned that engaging and persuading people in their schools to move toward change went beyond simply getting the job done. The findings reframe traditional notions of leadership from role and authority dependent to reciprocal, purposeful learning among adults in community. These new conceptions enabled participants to develop approaches whereby power, authority, responsibility, and resources can be redistributed in classrooms, schools, districts, and social organizations.
Are mechanics different between male and female runners with patellofemoral pain?

INTRODUCTION Patellofemoral pain (PFP) has often been attributed to abnormal hip and knee mechanics in females. To date, there have been few investigations of the hip and knee mechanics of males with PFP. The purpose of this study was to compare the lower extremity mechanics and alignment of male runners with PFP with healthy male runners and female runners with PFP. We hypothesized that males with PFP would move with greater varus knee mechanics compared with male controls and compared with females with PFP. Furthermore, it was hypothesized that males with PFP would demonstrate greater varus alignment. METHODS A gait and single-leg squat analysis was conducted on each group (18 runners per group). Measurement of each runner's tibial mechanical axis was also recorded. Motion data were processed using Visual 3D (C-Motion, Bethesda, MD). ANOVAs were used to analyze the data. RESULTS Males with PFP ran and squatted in greater peak knee adduction and demonstrated greater peak knee external adduction moment compared with healthy male controls. In addition, males with PFP ran and squatted with less peak hip adduction and greater peak knee adduction compared with females with PFP. The static measure of mechanical axis of the tibial was not different between groups. However, a post hoc analysis revealed that males with PFP ran with greater peak tibial segmental adduction. CONCLUSION Males with PFP demonstrated different mechanics during running and during a single-leg squat compared with females with PFP and with healthy males. Based upon the results of this study, therapies for PFP may need to be sex specific.
A Qualitative Model for Temporal Reasoning with Incomplete Information

We develop a qualitative framework for temporal reasoning with incomplete information that features a modeling language based on rules and a semantics based on infinitesimal probabilities. The framework relates logical and probabilistical models, and accommodates in a natural way features that have been found problematic in other models like nondeterminism, action qualifications, parallel actions, and abduction to actions and fluents.
Computational methodologies for modelling, analysis and simulation of signalling networks

This article is a critical review of computational techniques used to model, analyse and simulate signalling networks. We propose a conceptual framework, and discuss the role of signalling networks in three major areas: signal transduction, cellular rhythms and cell-to-cell communication. In order to avoid an overly abstract and general discussion, we focus on three case studies in the areas of receptor signalling and kinase cascades, cell-cycle regulation and wound healing. We report on a variety of modelling techniques and associated tools, in addition to the traditional approach based on ordinary differential equations (ODEs), which provide a range of descriptive and analytical powers. As the field matures, we expect a wider uptake of these alternative approaches for several reasons, including the need to take into account low protein copy numbers and noise and the great complexity of cellular organisation. An advantage offered by many of these alternative techniques, which have their origins in computing science, is the ability to perform sophisticated model analysis which can better relate predicted behaviour and observations.
ryanodine receptor Ca 2+ ion permeation and release from the sarcoplasmic reticulum

The RYR1 functions as the Ca release channel in the skeletal muscle SR. The functional RYR1 SR Ca release channel is a 2.3-megadalton homomeric assembly of four 565-kD RYR1 subunits. Each RYR1 subunit is composed of a large N-terminal cytosolic “foot” region and six to eight transmembrane sequences located within the C-terminal portion of the protein (Du et al., 2002, 2004). By analogy with known K channel structures, the selectivity filter of the RYR1 Ca release channel is determined by a conserved hydrophobic sequence Gly-Ile-Gly (amino acids 4894-4895-4896 in mouse RYR1) (Zhao et al., 1999; Gao et al., 2000; Williams et al., 2001) located between the final two transmembrane domains. Fully assembled tetrameric Ca release channels
Extensive Hair-Shaft Elongation by Isolated Mouse Whisker Follicles in Very Long-Term Gelfoam® Histoculture

We have previously studied mouse whisker follicles in Gelfoam® histoculture to determine the role of nestin-expressing plutipotent stem cells, located within the follicle, in the growth of the follicular sensory nerve. Long-term Gelfoam® whisker histoculture enabled hair follicle nestin-expressing stem cells to promote the extensive elongation of the whisker sensory nerve, which contained axon fibers. Transgenic mice in which the nestin promoter drives green fluorescent protein (ND-GFP) were used as the source of the whiskers allowing imaging of the nestin-expressing stem cells as they formed the follicular sensory nerve. In the present report, we show that Gelfoam®-histocultured whisker follicles produced growing pigmented and unpigmented hair shafts. Hair-shaft length increased rapidly by day-4 and continued growing until at least day-12 after which the hair-shaft length was constant. By day-63 in histoculture, the number of ND-GFP hair follicle stem cells increased significantly and the follicles were intact. The present study shows that Gelfoam® histoculture can support extensive hair-shaft growth as well as hair follicle sensory-nerve growth from isolated hair follicles which were maintained over very long periods of time. Gelfoam® histoculture of hair follicles can provide a very long-term period for evaluating novel agents to promote hair growth.
Evidence of Circadian Rhythm, Oxygen Regulation Capacity, Metabolic Repeatability and Positive Correlations between Forced and Spontaneous Maximal Metabolic Rates in Lake Sturgeon Acipenser fulvescens

Animal metabolic rate is variable and may be affected by endogenous and exogenous factors, but such relationships remain poorly understood in many primitive fishes, including members of the family Acipenseridae (sturgeons). Using juvenile lake sturgeon (Acipenser fulvescens), the objective of this study was to test four hypotheses: 1) A. fulvescens exhibits a circadian rhythm influencing metabolic rate and behaviour; 2) A. fulvescens has the capacity to regulate metabolic rate when exposed to environmental hypoxia; 3) measurements of forced maximum metabolic rate (MMRF) are repeatable in individual fish; and 4) MMRF correlates positively with spontaneous maximum metabolic rate (MMRS). Metabolic rates were measured using intermittent flow respirometry, and a standard chase protocol was employed to elicit MMRF. Trials lasting 24 h were used to measure standard metabolic rate (SMR) and MMRS. Repeatability and correlations between MMRF and MMRS were analyzed using residual body mass corrected values. Results revealed that A. fulvescens exhibit a circadian rhythm in metabolic rate, with metabolism peaking at dawn. SMR was unaffected by hypoxia (30% air saturation (O2sat)), demonstrating oxygen regulation. In contrast, MMRF was affected by hypoxia and decreased across the range from 100% O2sat to 70% O2sat. MMRF was repeatable in individual fish, and MMRF correlated positively with MMRS, but the relationships between MMRF and MMRS were only revealed in fish exposed to hypoxia or 24 h constant light (i.e. environmental stressor). Our study provides evidence that the physiology of A. fulvescens is influenced by a circadian rhythm and suggests that A. fulvescens is an oxygen regulator, like most teleost fish. Finally, metabolic repeatability and positive correlations between MMRF and MMRS support the conjecture that MMRF represents a measure of organism performance that could be a target of natural selection.
Effects of Word Confusion Networks on Voice Search

Mobile voice-enabled search is emerging as one of the most popular applications abetted by the exponential growth in the number of mobile devices. The automatic speech recognition (ASR) output of the voice query is parsed into several fields. Search is then performed on a text corpus or a database. In order to improve the robustness of the query parser to noise in the ASR output, in this paper, we investigate two different methods to query parsing. Both methods exploit multiple hypotheses from ASR, in the form of word confusion networks, in order to achieve tighter coupling between ASR and query parsing and improved accuracy of the query parser. We also investigate the results of this improvement on search accuracy. Word confusion-network based query parsing outperforms ASR 1-best based query-parsing by 2.7% absolute and the search performance improves by 1.8% absolute on one of our data sets.
Outdoor Augmented Reality: State of the Art and Issues

The goal of an outdoor augmented reality system is to allow the human operator to move freely without restraint in its environment, to view and interact in real time with geo-referenced data via mobile wireless devices. This requires proposing new techniques for 3D localization, visualization and 3D interaction, adapted to working conditions in outdoor environment (brightness variation, features of displays used, etc.). This paper surveys recent advances in outdoor augmented reality. It resumes a large retrospective of the work carried out in this field, especially on methodological aspects (localization methods, generation of 3D models, visualization and interaction approaches), technological aspects (sensors, visualization devices and architecture software) and industrial aspects.
