WozARd: a wizard of oz tool for mobile AR

Wizard of Oz methodology is useful when conducting user studies of a system that is in early development. It is essential to be able to simulate part of the system and to collect feedback from potential users. Using a human to act as the system is one way to do this. The Wizard of Oz tool presented here is called WozARd and it aims at offering a set of tools that help the test leader control the visual, tactile and auditive output that is presented to the test participant. Additionally, it is suitable for using in an augmented reality environment where images are overlaid on the phone's camera view or on glasses. The main features that were identified as necessary include presentation of media such as images, video and sound, navigation and location based triggering, automatically taking photos, capability to log test results and visual feedback, and the integration of Sony SmartWatch for interaction possibilities.

Lateralization of cerebral blood flow velocity changes during cognitive tasks. A simultaneous bilateral transcranial Doppler study.

BACKGROUND AND PURPOSE Transcranial Doppler ultrasonography (TCD) permits the assessment of cognitively induced cerebral blood flow velocity (BFV) changes. We sought to investigate the lateralization of BFV acceleration induced by a variety of cognitive tasks and to determine the influence of age, gender, IQ, and quality of the performance on the relative BFV changes. METHODS Simultaneous bilateral TCD monitoring of BFV in the middle cerebral arteries (MCAs) was performed in 90 normal right-handed volunteers during 13 verbal and visuospatial tasks and their preceding rest periods. RESULTS All tasks induced a significant bilateral BFV increase in the MCAs compared with the preceding rest periods. Five verbal tasks showed a significant left-hemispheric BFV acceleration. Linguistic tasks that required active or creative processing of the verbal stimuli, such as sentence construction or word fluency, elicited the most asymmetric response. Five visuospatial tasks revealed a significant right-hemispheric BFV shift. Paradigms that combined visuospatial attention and visuomotor manipulation showed the most lateralized acceleration. Older volunteers (aged >50 years) showed higher relative BFV changes, but lateralization was not influenced by age. Gender, IQ, and performance quality did not reveal significant effects on BFV change. CONCLUSIONS Bilateral TCD is a noninvasive technique that has the potential to connect the particular change in flow pattern of the MCA distribution with selective cognitive activity and thus offers specific functional information of scientific and clinical value.
Phonological word-form learning

has been approved by the Examining Committee for the thesis requirement for the Master of Arts degree in Psychology at the May 2010 graduation. ii To Dad iii ACKNOWLEDGMENTS I would like to extend a special thank you Jessi Hattori for recording the disyllabic and Jamie Tisdale for recording the monosyllabic nonword corpora used as stimuli in these experiments. I would also like to thank the many members of the Language and Memory Lab who assisted in data collection and scoring. iv ABSTRACT Seven experiments examined phonological word-form learning (i.e., the learning of novel wordlike sound patterns) after differing types of training. In each case, learning at the end of training was assessed via stem completion ability. Experiment 1 presented participants with eleven epochs of listening and repeating (incidental phonological learning) and found significant stem completion ability. The results of Experiment 2 showed greater stem completion ability after eleven epochs of listening and repeating along with repeated stem completion testing (deliberate phonological learning). Experiment 3 replicated results from Experiments 1 and 2 in a within-subject design and demonstrated that deliberate phonological learning is item-specific and not merely the result of generalized task facilitation. Experiment 4 measured stem completion ability after one hundred epochs of incidental phonological learning and found that it remained lower than after only eleven blocks of deliberate phonological learning in Experiments 2 and 3. Experiments 5, 6, and 7 utilized monosyllabic nonword stimuli, in contrast to the disyllabic nonword stimuli utilized in the first four experiments, and replicated the overall results from Experiments 1, 2, and 3, respectively. Taken together, these results suggest that incidental phonological learning does not yield full mastery of phonological word-forms.
Pie: scalable routing in peer-to-peer networks

Distributed hash tables (DHTs) are a class of algorithms used to store and retrieve information in peer-to-peer (P2P) systems in a scalable and robust fashion. Pie, a routing protocol for a new DHT framework, is presented. The performance of this algorithm is empirically compared to an existing DHT framework, Chord. Results show that Pie performs better than Chord with respect to the number of logical hops. It also yields a smaller delay and better load balancing. The results are supported by a paired t-test at an alpha level of 0.01.
Age- and diet-associated metabolome remodeling characterizes the aging process driven by damage accumulation

Aging is thought to be associated with increased molecular damage, but representative markers vary across conditions and organisms, making it difficult to assess properties of cumulative damage throughout lifespan. We used nontargeted metabolite profiling to follow age-associated trajectories of >15,000 metabolites in Drosophila subjected to control and lifespan-extending diets. We find that aging is associated with increased metabolite diversity and low-abundance molecules, suggesting they include cumulative damage. Remarkably, the number of detected compounds leveled-off in late-life, and this pattern associated with survivorship. Fourteen percent of metabolites showed age-associated changes, which decelerated in late-life and long-lived flies. In contrast, known metabolites changed in abundance similarly to nontargeted metabolites and transcripts, but did not increase in diversity. Targeted profiling also revealed slower metabolism and accumulation of lifespan-limiting molecules. Thus, aging is characterized by gradual metabolome remodeling, and condition- and advanced age-associated deceleration of this remodeling is linked to mortality and molecular damage.

Process Model Representation Layers for Financial Audits

Business processes play a significant role in financial audits. They are carried out by auditors who require diverse information for this purpose. Process mining techniques offer new opportunities to exploit data from ERP systems to generate reliable process models very effectively and efficiently. Traditional process models are only suited to provide information on a single process. This study illustrates how diverse information aspects that are required for process audits can be provided to the auditor by using different process model types that relate to different representation layers. Process mining techniques commonly operate on the business process and instance level. This study introduces process map and process stream models as higher level abstractions of multiple business processes. The introduction of higher-level process models in combination with traditional model types allows an all-encompassing representation of information aspects that are relevant for process audits in the context of financial audits.
El tiempo: una dimensión clave en el estudio de la atención

Resumen Este trabajo revisa la investigación experimental que ha estudiado el tiempo como la dimensión básica del proceso cognitivo atencional. Concretamente, analizamos cuatro modos posibles de interacción entre atención y tiempo que están presentes en un amplio rango de actividades humanas e interacciones con el medio. Primero, la atención es un proceso sujeto a limitaciones temporales que requiere cierto tiempo para lograr un procesamiento controlado de los estímulos. Segundo, el grado de atención que prestamos al fluir del tiempo modifica nuestra percepción subjetiva del mismo, abreviándolo o prolongándolo. Tercero, esta relación también se observa en sentido inverso, tal que la estructura temporal del ambiente determina nuestro proceso de focalización u orientación atencional hacia un instante en el tiempo. Cuarto, dicho proceso de orientación temporal no sólo es guiado exóge- namente por ritmos externos: también se puede controlar endógenamente mediante expectativas temporales que genera el individuo a partir de información explícita sobre cuándo ocurrirá un evento. Como conclusión, se acentúa la importancia de considerar la dimensión temporalen el estudio de procesos cognitivos como la atención, que subyacen a nuestras interacciones con el medio.
Asymptotically hyperbolic non-constant mean curvature solutions of the Einstein constraint equations

We describe how the iterative technique used by Isenberg and Moncrief to verify the existence of large sets of non-constant mean curvature solutions of the Einstein constraints on closed manifolds can be adapted to verify the existence of large sets of asymptotically hyperbolic non-constant mean curvature solutions of the Einstein constraints.
Excellent school performance at age 16 and risk of adult bipolar disorder: national cohort study

Background Anecdotal and biographical reports suggest that bipolar disorder may be associated with high IQ or creativity, but evidence for any such connection is weak. Aims To investigate possible associations between scholastic achievement and later bipolar disorder, using prospective data, in a whole-population cohort study. Method Using individual school grades from all individuals finishing compulsory schooling in Sweden between 1988 and 1997, we tested associations between scholastic achievement at age 15–16 and hospital admission for psychosis between ages 17 and 31, adjusting for potential confounders. Results Individuals with excellent school performance had a nearly fourfold increased risk of later bipolar disorder compared with those with average grades (hazard ratio HR = 3.79, 95% CI 2.11–6.82). This association appeared to be confined to males. Students with the poorest grades were also at moderately increased risk of bipolar disorder (HR = 1.86, 95% CI 1.06–3.28). Conclusions These findings provide support for the hypothesis that exceptional intellectual ability is associated with bipolar disorder.
Ethnic Variations in Severe Maternal Morbidity in the UK– A Case Control Study

Background Previous studies showed a higher risk of maternal morbidity amongst black and other minority ethnic (BME) groups, but were unable to investigate whether this excess risk was concentrated within specific BME groups in the UK. Our aim was to analyse the specific risks and to investigate reasons for any disparity. Methods Unmatched case-control analysis using data from the United Kingdom Obstetric Surveillance System (UKOSS), February 2005-January 2013. Cases were 1,753 women who experienced severe morbidity during the peripartum period. Controls were 3,310 women who delivered immediately before the cases in the same hospital. Multivariable logistic regression modelling was used to adjust for known confounders and to understand their effects. Results Compared with white European women, the odds of severe maternal morbidity were 83% higher among black African women (adjusted odds ratio (aOR) = 1.83; 95% Confidence Interval (CI) = 1.39–2.40), 80% higher among black Caribbean (aOR = 1.80; 95% CI = 1.14–2.82), 74% higher in Bangladeshi (aOR = 1.74; 95% CI = 1.05–2.88), 56% higher in other non-whites (non-Asian) (aOR = 1.56; 95% CI = 1.05–2.33) and 43% higher among Pakistani women (aOR = 1.43; 95% CI = 1.07–1.92). There was no evidence of substantial confounding. Anaemia in current pregnancy, previous pregnancy problems, inadequate utilisation of antenatal care, pre-existing medical conditions, parity>3, and being younger and older were independent risk factors but, the odds of severe maternal morbidity did not differ by socioeconomic status, between smokers and non-smokers or by BMI. Discussion This national study demonstrates an increased risk of severe maternal morbidity among women of ethnic minority backgrounds which could not be explained by known risk factors for severe maternal morbidity.
Eléments d'une approche constructiviste des structures organisationnelles : cas de la structuration d'un champ micro-informatique à la RATP

Les approches constructivistes connaissent de nos jours un grand succes dans les champs de l'epistemologie, de la psychologie cognitive et de la sociologie. Le champ des sciences de gestion, en dehors de quelques tentatives isolees, n'a pas encore vraiment integre les idees constructivistes. En temoigne la position encore dominante des deux modeles du mecanisme et de l'organisme dans les travaux des theoriciens des organisations, notamment en milieu anglo-saxon. La these, issue d'un travail de terrain de plus de deux ans dans une grande organisation, contient une discussion critique de travaux representatifs des deux modeles du mecanisme et de l'organisme. Elle tente, en outre, d'apporter une contribution a l'elaboration d'une approche constructiviste des organisations. Les idees de Jean Piaget et de la theorie de la structuration de Anthony Giddens, deux eminents representants du paradigme constructiviste en sciences sociales, sont discutees et ont servi a formuler un modele constructiviste de l'organisation. La capacite explicative de l'approche constructiviste est illustree par l'analyse du processus de structuration d'un champ micro-informatique a la RATP. Des stades de structuration caracterises par differentes configurations structurelles sont clairement identifies. Les facteurs ayant intervenu a chaque stade sont analyses et les liens entre stades successifs sont mis en evidence.
A Load-balancing Clustering Algorithm of WSN for Data Gathering

Xiang Lia Load-balancing Clustering Algorithm of WSN for Data Gathering (LCA-DG) is proposed based on load equalization. The LCA-DG uses the comprehensive weight value that composed of two factors, that distance between head and members and residual energy, to improve cluster members choice strategy for balancing load of each bunch, and uses optimization threshold value and receiving threshold value to avoid the new load imbalance that may occur after optimizing. So that the network lifetime can be further extended and the algorithm is suitable for large-scale sensor network.
Soil properties estimates from SAR data by using a bayesian approach combined with IEM

An experiment aimed at investigating the potential of ENVISAT/ASAR in measuring soil moisture is described in this paper. Two test areas were chosen as test sites: Montespertoli and Alessandria, in Central and Northern Italy, respectively. After a preliminary analysis of the direct relationship between the backscattering coefficient at C-band and the soil moisture content of individual fields, a Bayesian approach was attempted for retrieving soil moisture. To obtain a statistically significant data set, simulations performed with the integral equation model were added to experimental data. Moreover, an artificial neural network was tested on Alessandria area
Comparison of subjective sleep quality in patients with cancer and healthy subjects.

PURPOSE/OBJECTIVES To compare the subjective sleep quality of a group of patients with cancer undergoing treatment and a normative sample of healthy comparison subjects. DESIGN Secondary analysis of data from a single time point in a repeated measures descriptive-correlational study. SAMPLE/SETTING Convenience sample of 15 patients with cancer receiving antineoplastic therapy and admitted to a tertiary university medical center for fever or neutropenia and 52 healthy comparison subjects without sleep disturbances. Although both groups were of similar age, a higher percentage of men comprised the comparison group. METHODS Patients completed the Pittsburgh Sleep Quality Index (PSQI) on the first day of hospitalization to reflect their perceptions of sleep for the month prior to hospitalization. Healthy comparison subject scores on the PSQI were obtained from a published report outlining psychometric properties of the PSQI (Buysse, Reynolds, Monk, Berman, & Kupfer, 1989). MAIN RESEARCH VARIABLES Sleep latency, sleep duration, sleep efficiency, sleep disturbances, medication use, daytime dysfunction, and global sleep quality. FINDINGS Patients with cancer reported significantly poorer overall sleep quality accompanied by more daytime dysfunction. The incidence of specific sleep disturbances, such as snoring and dyspnea, was not different between the groups. CONCLUSIONS This small sample of patients reported significantly poorer sleep quality than an historical comparison group. Specific sleep disturbances commonly seen in the general population were not problematic for the patients with cancer. Limited sample size and use of an historical comparison group need to be considered in interpreting and applying these findings. Additional research is needed to further characterize the nature of sleep problems in patients with cancer. IMPLICATIONS FOR NURSING PRACTICE Nurses need to assess sleep in their patients, including its impact on quality of life and functional status.
Investigating the relationship between peak inspiratory flow rate and volume of inhalation from a DiskusTM Inhaler and baseline spirometric parameters: a cross-sectional study

Drug delivery from a Dry Powder Inhaler (DPI) is dependent on the peak inspiratory flow rate (PIFR) generated. Currently available methods for estimating PIFR from most DPIs are limited and mainly rely on subjective assessment. We aim to show that spirometric and DiskusTM PIFR and Inspiratory Vital Capacity (IVC) are related to the underlying respiratory condition and that spirometric PIFR can be used to assess whether DiskusTM PIFR will be adequate when using this DPI. Healthy volunteers and patients with asthma, COPD, neuromuscular disease and non-respiratory disorders were recruited (n = 85). Demographics and baseline lung function by spirometry were recorded. Flow and volume readings were taken while patients used a DiskusTM DPI, housed in an airtight container connected to a spirometer. T-tests were performed to compare mean spirometric and DiskusTM PIFR/ IVC between groups. Stepwise regression analysis of DiskusTM PIFR versus spirometric PIFR, spirometric IVC, age, gender, condition, BMI, FEV1 and FVC was performed. The DiskusTM PIFR for the COPD and Neuromuscular Disease group was more than 10 L/min lower than the Healthy or Asthma groups (p < 0.05). The mean spirometric and DiskusTM IVC of the Healthy group was significantly (>0.75 L) higher than the mean for the other three groups (p < 0.05). DiskusTM PIFR was moderately correlated with spirometric PIFR and age (Adjusted R = 0.58, p < 0.0001). PIFR generated using a DiskusTM DPI is dependent on the underlying disease and age. A spirometric PIFR of less than 196 L/min should prompt further investigation into the suitability of a patient for a DiskusTM DPI, with possible consideration of alternate devices.
KRDB Research Centre Technical Report : Checking Query Completeness over Incomplete Data

Data completeness is an important aspect of data quality as in many scenarios, it is crucial to guarantee completeness of query answers. We develop techniques to conclude the completeness of query answers from information about the completeness of parts of a generally incomplete database. In our framework, completeness of a database can be described in two ways: by table completeness (TC) statements that describe the completeness of parts of relations, and query completeness (QC) statements that describe the completeness of query answers. We show for conjunctive queries without comparisons that the problem of table completeness entailing query completeness (TC-QC) can be reduced to the TC-TC entailment problem. We also show that the latter is equivalent to query containment, thus making algorithms developed for this problem available for managing data completeness. For the related problem of QC-QC entailment, we discuss its connection to query determinacy. Furthermore, we show that additional completeness inferences are possible in the presence of finite domain constraints or if the concrete state of a database is taken into account. In both cases, however, completeness reasoning becomes computationally harder.
Dynamic Range Compression in the Honey Bee Auditory System toward Waggle Dance Sounds

Honey bee foragers use a “waggle dance” to inform nestmates about direction and distance to locations of attractive food. The sound and air flows generated by dancer's wing and abdominal vibrations have been implicated as important cues, but the decoding mechanisms for these dance messages are poorly understood. To understand the neural mechanisms of honey bee dance communication, we analyzed the anatomy of antenna and Johnston's organ (JO) in the pedicel of the antenna, as well as the mechanical and neural response characteristics of antenna and JO to acoustic stimuli, respectively. The honey bee JO consists of about 300–320 scolopidia connected with about 48 cuticular “knobs” around the circumference of the pedicel. Each scolopidium contains bipolar sensory neurons with both type I and II cilia. The mechanical sensitivities of the antennal flagellum are specifically high in response to low but not high intensity stimuli of 265–350 Hz frequencies. The structural characteristics of antenna but not JO neurons seem to be responsible for the non-linear responses of the flagellum in contrast to mosquito and fruit fly. The honey bee flagellum is a sensitive movement detector responding to 20 nm tip displacement, which is comparable to female mosquito. Furthermore, the JO neurons have the ability to preserve both frequency and temporal information of acoustic stimuli including the “waggle dance” sound. Intriguingly, the response of JO neurons was found to be age-dependent, demonstrating that the dance communication is only possible between aged foragers. These results suggest that the matured honey bee antennae and JO neurons are best tuned to detect 250–300 Hz sound generated during “waggle dance” from the distance in a dark hive, and that sufficient responses of the JO neurons are obtained by reducing the mechanical sensitivity of the flagellum in a near-field of dancer. This nonlinear effect brings about dynamic range compression in the honey bee auditory system.
