The KiddyCAT: A Test-Retest Reliability Investigation

Research with the Communication Attitude Test for Preschool and Kindergarten Children who Stutter (KiddyCAT) in the United States, Italy and Poland has shown that, as a group, preschool and kindergarten children who stutter report, as of the age of three, already significantly more in the way of a negative attitude toward speech compared to their nonstuttering peers. In addition to its discriminative usefulness, the test’s validity has been established. What still needed to be determined was the KiddyCAT’s test-retest reliability, which was the aim of this investigation. In order to do so, a Dutch form of the KiddyCAT was administered to a sample of 34 stuttering and 42 nonstuttering children between the age of three and six on two separate occasions. After the initial testing, the children were retested a week to 12 days later. For both groups of participants, the scores of the first and second test administration correlated significantly, and the average scores did not differ from each other to a statistically significant extent. Thus, the repeated administration of the test revealed that the obtained first and second test scores were highly dependent and predictable from each other, and stable over time. As a side issue, it was, once again, confirmed that the scores of the children who do and do not stutter differed to a statistically significant extent.
Marker assisted selection: a paradigm shift in Basmati breeding

Marker assisted backcross breeding (MABB) provides a great opportunity for precise transfer of desirable donor segment by minimizing the linkage drag into a recurrent parent. In our lab, MABB was used for incorporating bacterial blight (BB) resistance genes (xa13 and Xa21) into the genetic background of Pusa Basmati1, which led to development of Improved Pusa Basmati 1 (Pusa 1460) as one of the first products of molecular breeding. Further, the parental lines of superfine grain aromatic rice hybrid Pusa RH 10 namely, Pusa 6A, Pusa 6B and PRR78 were improved for resistance to BB and blast by transferring genes xa13+Xa21 and Pi54 +Piz5, respectively. Presently, the pyramiding of genes for resistance to BB (xa13 and Xa21), blast (Piz5 and Pi54) and brown plant hopper (BPH; Bph 3, Bph 17, Bph 18, Bph20 and Bph 21) into Basmati rice varieties viz., Pusa Basmati 1121 and Pusa Basmati 6 is under way. In addition, a major QTL for salt tolerance (Saltol) is being transferred to Pusa Basmati 1121, which is widely grown in Haryana, the state having problem of salinity owing to underground brackish water. In order to develop genetically enhanced donor sources for resistance to biotic (BB, blast and BPH) and abiotic (salt tolerance, and phosphorus uptake) stresses in Basmati background, isogenic lines are being developed for major resistance genes/QTLs for respective stresses in the background of Pusa Basmati 1. Molecular mapping of fertility restorer gene(s) in Basmati restorer line PRR78 led to identification of two Rf gene linked molecular markers, RM258 and RM6100. Of these, RM6100 on validation in a set of rice germplasm showed 97.4% efficacy in identifying restorer lines from germplasm. QTL mapping using RIL population has unveiled several novel QTLs for grain and cooking quality traits. Molecular markers are also being routinely used for establishing variety/hybrids identity and authentication of genetic purity of hybrid seed lots.
Practical experience of virtual team software development

Given the current popularity of Global Software Development (GSD) increasing numbers of organisations are taking the opportunity offered to set up virtual software teams. This approach allows companies to partner experienced engineers located in high cost economic areas with less experienced team members based in low cost centres allowing both locations to be leveraged to their best advantage. A number of different approaches are currently being undertaken. Some organisations have set up subsidiaries in low cost economies and are developing virtual teams in this environment. Others are partnering with third party outsourcing organisations. The focus of this research is an Irish based company partnered with an organisation located in the US to develop and maintain bespoke financial software. A number of virtual teams were established, each team had members based in the US and Ireland. Given the locations involved it was initially believed that the organisations were culturally near shore. While that proved correct to a point, it soon became clear that communication, motivation and cultural differences existed and needed to be addressed. It was also realised that a new approach to process development and improvement had to be undertaken to ensure the successful development and operation of these virtual teams. Both organisations had good single site development and maintenance processes, but they proved inadequate for a multi-site GSD environment and needed to be extensively reengineered. Initially mistakes were made and areas of conflict arose. Rather than view these events as negative, each was leveraged to insure that the process was improved to address and minimise any reoccurrence. As a result over a four-year period a very successful common virtual team development process evolved between both organisations. This paper outlines some of the key problem areas encountered and offers practical advice and experience on how they were successfully addressed. Given the importance of GSD to the software industry this experience should be of value to anyone interested in outsourcing and virtual team software development and maintenance.
Characteristics of Diurnal Pulses Observed in Typhoon Atsani Using Retrieved Cloud Property Data

Using several cloud properties retrieved from the Himawari-8 satellite, combined with the best track storm center information, the temporal-spatial features of tropical cyclone (TC) diurnal pulses in 2015 Super Typhoon Atsani (T1516) are coherently depicted. To demonstrate the radially outward transition processes of the diurnal pulses from one cloud type to another, we divided high clouds into three types: opaque high cloud (OHC), cirrostratus (Cs), and cirrus (Ci). Two alternatively appeared peaks in cloud top height (CTH) within the storm central area and their corresponding outward pulses are identified. The first pulse covers a 24-hour period, it starts at ~0500−0700 local solar time (LST), with a gradual transition from OHC to Cs, then ends in Ci at around 0400 LST. The second pulse lasts for half a day and limited within 1000 km from the storm center. When the first CTH pulse ends in OHC, Cs, and Ci, their cloud fractional coverage and the outward expansion of large cloud optical thickness also reach maximum accordingly. (Citation: Wang, X., H. Iwabuchi, and N. Takahashi, 2019: Characteristics of diurnal pulses observed in Typhoon Atsani using retrieved cloud property data. SOLA, 15, 137−142, doi:10.2151/ sola.2019-025.)
Assimilation of Ocean-Color Plankton Functional Types to Improve Marine Ecosystem Simulations

We assimilated plankton functional types (PFTs) derived from ocean colour into a marine ecosystem model, to improve the simulation of biogeochemical indicators and emerging properties in a shelf sea. Error-characterized chlorophyll concentrations of four PFTs (diatoms, dinoflagellates, nanoplankton and picoplankton), as well as total chlorophyll for comparison, were assimilated into a physical-biogeochemical model of the North East Atlantic, applying a localized Ensemble Kalman filter. The reanalysis simulations spanned the years 1998 to 2003. The skill of the reference and reanalysis simulations in estimating ocean colour and in situ biogeochemical data were compared by using robust statistics. The reanalysis outperformed both the reference and the assimilation of total chlorophyll in estimating the ocean-colour PFTs (except nanoplankton), as well as the not-assimilated total chlorophyll, leading the model to simulate better the plankton community structure. Crucially, the reanalysis improved the estimates of not-assimilated in situ data of PFTs, as well as of phosphate and pCO2, impacting the simulation of the air-sea carbon flux. However, the reanalysis increased further the model overestimation of nitrate, in spite of increases in plankton nitrate uptake. The method proposed here is easily adaptable for use with other ecosystem models that simulate PFTs, for, e.g., reanalysis of carbon fluxes in the global ocean and for operational forecasts of biogeochemical indicators in shelf-sea ecosystems.
Radiocarbon Dating of Lumps from Aerial Lime Mortars and Plasters: Methodological Issues and Results from San Nicolò of Capodimonte Church (Camogli, Genoa, Italy)

This paper deals with the potentialities and technical and methodological issues associated with the use of lumps of not completely melted lime as material suitable for the radiocarbon dating of aerial lime mortars and plasters. In fact, the identification and selection of single aggregates of unmelted lumps allows one to reduce the possible contamination resulting from external sources of carbon such as “14C-dead” limestone in sand added to the mixture during preparation. This procedure results in the possibility for accurate 14C determinations from single pieces of masonry, supplying important information about the construction phases of historical buildings. The potential of this approach is shown by presenting the results of the archaeological study on the walls of San Nicolò of Capodimonte church (Camogli, Genoa, Italy), where this technique has been successfully applied to obtain absolute ages of different parts of the building. The obtained results were then compared with the information gathered from historical sources and with stratigraphic and other archaeological studies.
Spectrum and variability of the Galactic Center VHE gamma-ray source HESS J1745-290

A detailed study of the spectrum and variability of the source HESS J1745-290 in the Galactic Center (GC) region using new data from the H.E. S.S. array of Cherenkov telescopes is presented. Flaring activity and Quasi Periodic Oscillations (QPO) of HESS J1745-290 are investigated. The image analysis is performed with a combination of a semi-analytical shower model and the statistical moments based Hillas technique. The spectrum and lightcurves of HESS J1745-290 are derived with a likelihood method based on a spectral shape hypothesis. Rayleigh tests and Fourier analysis of the H.E. S.S. GC signal are used to study the periodicity of the source. With three-fold increase in statistics compared to previous work, a deviation from a simple power law spectrum is detected for the first time. The measured energy spectrum over the three years 2004, 2005 and 2006 of data taking is compatible with both a power law spectrum with an exponential cut-off and a broken power law spectrum. The curvature of the energy spectrum is likely to be intrinsic to the photon source as opposed to effects of interstellar absorption. No significant flux variation is found. Increases in the gamma-ray flux of HESS J1745-290 by at least a factor of two would be required for a 3 sigma detection of a flare of time scales of an hour. Investigation of possible QPO activity at periods claimed to be detected in X-rays does not show any periodicities in the H.E. S.S. signal.
Spectroscopic detection of a ubiquitous dissolved pigment degradation product in subsurface waters of the global ocean

Abstract. Measurements of light absorption by chromophoric dissolved organic matter (CDOM) from subsurface waters of the tropical Atlantic and Pacific Oceans showed a distinct absorption shoulder at 410–415 nm. This indicates an underlying absorption of a pigment whose occurrence is partly correlated with the apparent oxygen utilization (AOU) but also found in the deep chlorophyll maximum. A similar absorption maximum at ~415 nm was also found in the particulate fraction of samples taken below the surface mixing layer and is usually attributed to absorption by respiratory pigments of heterotrophic unicellular organisms. In our study, fluorescence measurements of pre-concentrated dissolved organic matter (DOM) samples from 200–6000 m confirmed a previous study suggesting that the absorption at ~415 nm was related to fluorescence at 650 nm in the oxygen minimum zone. The absorption characteristics of this fluorophore was examined by fluorescence emission/excitation analysis and showed a clear excitation maximum at 415 nm that could be linked to the absorption shoulder in the CDOM spectra. The spectral characteristics of the substance found in the dissolved and particulate fraction did not match with those of chlorophyll a degradation products (as found in a sample from the sea surface) but can be explained by the occurrence of porphyrin pigments from either heterotrophs or autotrophs. Combining the observations of the fluorescence and the 415-nm absorption shoulder suggests that there are high concentrations of a pigment degradation product in subsurface DOM of all major oceans. Most pronouncedly we found this signal in the deep chlorophyll maximum and the oxygen minimum zone of tropical regions. The origin, chemical nature, turnover rate, and fate of this molecule is so far unknown.
Promoting Species Establishment in a Phragmites-Dominated Great Lakes Coastal Wetland

ABSTRACT: This study examined efforts to promote species establishment and maintain diversity in a Phragmites-dominated wetland where primary control measures were underway. A treatment experiment was performed at Crane Creek, a drowned-river-mouth wetland in Ottawa National Wildlife Refuge along the shore of western Lake Erie. Following initial aerial spraying of Phragmites with glyphosate, this study tested combinations of cutting, raking, and additional hand spraying of Phragmites with glyphosate as methods to promote growth of other wetland species and increase plant diversity. Percent-cover vegetation data were collected in permanent plots before and after treatments, and follow-up sampling was performed the following year. Increased species richness, species emergence, and relative dominance of non-Phragmites taxa were used as measures of treatment success. We also examined treatment effects on Phragmites cover. Dimensionality of seedbank and soil properties was reduced using principal component analysis. With the exception of nitrogen, soil nutrients affected species establishment, non-Phragmites taxa dominance, and Phragmites cover. A more viable seedbank led to greater species emergence. Treatments had differential effects on diversity depending on elevation and resulting degree of hydrologic inundation. Whereas raking to remove dead Phragmites biomass was central to promoting species establishment in dry areas, spraying had a greater impact in continually inundated areas. For treatment success across elevations into the year following treatments, spraying in combination with cutting and raking had the greatest effect. The results of this study suggest that secondary treatments can produce a short-term benefit to the plant community in areas treated for Phragmites.
Conservation of Dutch Colonial Architecture Heritage On Rectorate Building of Education University of Indonesia in Bandung

This study aims to reveal the relationship between architecture and conservation of the Rectorate building of Education University of Indonesia (EUI) in Bandung, categorized as cultural heritage building. This study used qualitative method, through the steps: 1) revealing the building cultural significance of the form-function aspects. 2) Revealing the significant architectural elements to be conserved. 3) Describing the need of conservation treatment.The analysis was based on architectural theory (function-form-meaning) and conservation theory (value-based approach, ethics). The finding of this study: a) Cultural significance, consist of architectural significance (Europe Modern architecture adapted to local nature and culture) that relatively still steady, and historical significance (Dutch businessman house, part of Savoy Homann Hotel). b)The significant architectural elements were:Modern Architectural style at building envelope, the main entrance, rooms ordering resembled Sundanese architecture adapted to the North-South axis.c) The conservation treatment needed were preservation-consolidation on the building envelope, restoration on room ordering at centre part of the building, and adaptation of nowadays function to the building condition. d) The original and new parts of the building should be seen in harmony, but it still could be distinguished. Both of those must be supported by routine maintenance.
A Step toward Understanding Trust in the Government

Over the last fifty years, trust in government has declined. This paper seeks to further the understanding of trust in government. Using ordinal level survey data from 1998-2012, a crosstabular analysis is used to test governmental trust with broad and specific policy areas. This research challenges part of Popkin and Dimock’s (2000) research, which asserts that citizens use trust as a heuristic for both broad and specific questions about the government. The empirical findings suggest that citizens distrust the government broadly but trust a wide range of programs implemented by the very government they distrust.

Magnetically and optically tunable terahertz radiation from Ta/NiFe/Pt spintronic nanolayers generated by femtosecond laser pulses

We generate terahertz (THz) transients by illuminating a few-nanometer-thick Ta/NiFe/Pt nanolayers with a train of linearly polarized 100-fs-wide laser pulses. The transients are ∼1-ps-wide free-space propagating bursts of electromagnetic radiations with amplitudes that are magnetically and optically tunable. Their spectral frequency content extends up to 5 THz, and the 3-dB cutoff is at 0.85 THz. The observed transient electromagnetic signals originate from the NiFe/Pt bilayer, and their amplitude dependence on the external magnetic field, applied in the sample plane, very closely follows the static magnetization versus magnetic field dependence of the NiFe film. For the same laser power, excitation with highly energetic, blue light generates THz transients with amplitudes approximately three times larger than the ones resulting from excitation by infrared light. In both cases, the transients exhibit the same spectral characteristics and are linearly polarized in the perpendicular direction to the sample magnetization. The polarization direction can be tuned by rotation of the magnetic field around the laser light propagation axis. The characteristics of our THz spintronic emitter signals confirm that THz transient generation is due to the inverse spin Hall effect in the Pt layer and demonstrate that ferromagnet/metal nanolayers excited by femtosecond laser pulses can serve as efficient sources of magnetically and optically tunable, polarized transient THz radiation.We generate terahertz (THz) transients by illuminating a few-nanometer-thick Ta/NiFe/Pt nanolayers with a train of linearly polarized 100-fs-wide laser pulses.

Semiconducting Thienothiophene Copolymers: Design, Synthesis, Morphology, and Performance in Thin‐Film Organic Transistors

Organic semiconductors are emerging as a viable alternative to amorphous silicon in a range of thin‐film transistor devices. With the possibility to formulate these p‐type materials as inks and subsequently print into patterned devices, organic‐based transistors offer significant commercial advantages for manufacture, with initial applications such as low performance displays and simple logic being envisaged. Previous limitations of both air stability and electrical performance are now being overcome with a range of both small molecule and polymer‐based solution‐processable materials, which achieve charge carrier mobilities in excess of 0.5 cm2 V−1 s−1, a benchmark value for amorphous silicon semiconductors. Polymer semiconductors based on thienothiophene copolymers have achieved amongst the highest charge carrier mobilities in solution‐processed transistor devices. In this Progress Report, we evaluate the advances and limitations of this class of polymer in transistor devices.
Innovation, Productivity and Growth: An Analysis of Irish Panel Data

This paper examines the dynamics of knowledge sourcing, innovation and business performance for a panel of Irish manufacturing plants. A recursive system is estimated comprising an innovation production function which relates knowledge inputs to innovation success, and equations which relate innovation to productivity and growth. Results indicate that both internal (R&D) and external (supply chain and non-supply chain) sources of knowledge are important determinants of innovation success, and there is evidence of substitutability between them. Innovation has a strong positive effect on growth, and has a negative contemporaneous effect, but positive lagged effect, on productivity. Process innovation has a positive effect on productivity with no lagged effect. There is also evidence that skill levels are important both in shaping the ability of plants to be innovative, and in their ability to exploit innovation to achieve higher growth and productivity.
Determinants of Health Related Quality of Life among Adolescents with Migraine

TODOROV, BORIS K, M.S., June 2009, Clinical Psychology Determinants of Health Related Quality of Life among Adolescents with Migraine (55 pp.) Director of Thesis: Kenneth A. Holroyd This study examined data from 63 adolescents with migraine (45 female) between the ages of 11 and 17 (mean age=14.4) to compare the relative impact of migraine severity, associated symptom severity, internalizing symptoms and catastrophizing on health-related quality of life (HRQL). Participants kept a 4-week diary about their headaches and completed 3 different quality of life scales, a psychological assessment scale and a catastrophizing questionnaire. A hierarchical regression analysis revealed that associated symptoms of migraine and internalizing symptoms predicted adolescent functioning. This is the first study of its kind designed specifically for adolescents with migraine. Its results suggest there is a need for further research exploring the impact of associated symptoms of migraine and internalizing on HRQL of adolescents.
