Analyses of student performance indicated that subjects with internal locus of ccntrcl and analytic cognitive style gave more correct responses in the initial acquisitions phase than did externally controlled and global children. No difference was observed in the final acquisition block; however, when composite correct responses were analyzed, the analytic children were found superior to global children. Indiscriminate use of verbal support appeared to depress retardates' performance on a concept learning task. Implications concerning potency of social reinforcers and reevaluation of performance deficit in terms of non-intellective factors were noted.
33. MAGNETIC PROPERTIES OF BASALTS FROM DSDP LEG 49

Rock magnetism is the study of the fundamental magnetic properties of the magnetic minerals present in rocks. In submarine basalts the dominant carriers of the magnetic signal are titanomaghemites, which are titanomagnetites that have been oxidized to varying degrees at low temperatures. They are single phase and retain the spinel structure of the original titanomagnetite. High-temperature oxidation is generally absent in submarine basalts. Our knowledge of the magnetic properties of titanomaghemites is very limited. The most exhaustive study is that by Readman and O'Reilly (1972), who examined some of the magnetic properties of synthetic samples; but although their samples spanned the whole composition range of the titanomaghemites, their study was limited by the necessity for keeping grain size small if one is to produce single-phase oxidation products. The mean grain size in their samples was about 0.1 μm. So until a method is found to produce large-grain synthetic titanomaghemites, we are confined to studies of the natural grains in submarine basalts.
1 Blue Intensity based experiments for reconstructing North 1 Pacific temperatures along the Gulf of Alaska 2 3

Climate in the Gulf of Alaska (GOA) reflects large-scale ocean-atmosphere variability of the North 14 Pacific climate system. Ring-width (RW) records from the GOA have yielded a valuable long-term perspective for 15 North Pacific changes on decadal to longer time scales in prior studies, but express a broad winter to late summer 16 seasonal response. Similar to the highly climate-sensitive maximum latewood density (MXD) proxy, the Blue 17 Intensity (BI) parameter has recently been shown to correlate well with year-to-year warm-season temperatures for a 18 number of sites at northern latitudes. Since BI records are much less expensive and labor intensive to generate than 19 MXD, such data hold great potential value for future tree-ring studies in the GOA and other regions at mid-to-high 20 latitudes. Here we highlight the potential for improving tree-ring based reconstructions using combinations of RW 21 and BI-related parameters (latewood BI (LWB) and delta BI (DB)) from an experimental sub-set of samples from 22 eight mountain hemlock (Tsuga mertensiana) sites along the GOA. This is the first such study for the hemlock 23 genus using BI data. We find that using either LWB or DB can improve the amount of explained temperature 24 variance by > 10% compared to RW alone although the optimal target season changes to June-September, which 25 may have implications for studying ocean-atmosphere variability in the region. However, one challenge in building 26 these BI records is that resin extraction did not remove colour differences between the heartwood and sapwood, so 27 long term trend biases, expressed as relatively warm temperatures in the 18 century, were noted when using the 28 LWB data. Using DB appeared to overcome these trend biases resulting in a reconstruction expressing 18-19 29 century temperatures ca. 0.5C cooler than the 20/21 centuries. This cool period agrees well with previous 30 dendroclimatic studies and the glacial advance record in the region. Continuing BI measurement in the GOA region 31 must focus on sampling more trees per site (> 20) and more sites to overcome site specific factors effecting climate 32 response while sub-fossil material will extend the reflectance records back over 1000 years. DB appears to capture 33 long term secular trends that agree with other proxy archives in the region but great care is needed when 34 implementing different detrending options. Finally, more experimentation is needed to assess the utility of DB for 35 different conifer species around the Northern Hemisphere. 36 37
Studying hot exozodiacal dust with near-infrared interferometry

Since our first detection of a resolved near-infrared emission around the main sequence star Vega, which we identified as the signature of hot dust grains close to the sublimation limit, we have been systematically searching for similar signatures around a magnitude-limited sample of nearby main sequence stars with the FLUOR instrument at the CHARA array. About 40 targets with spectral types ranging from A to K have been observed within the last 6 years, leading to first statistical trends on the occurence of the bright exozodi phenomenon as a function of spectral type. Our target sample is balanced between stars known to harbour cold dust populations from space-based missions (e.g., Spitzer, Herschel) and stars without cold dust, so that the occurence of abundant hot dust can also be correlated with the presence of large reservoirs of cold planetesimals. In this paper, we present preliminary conclusions from the CHARA/FLUOR survey. We also discuss the first results obtained in 2011/2012 with the new PIONIER visiting instrument at the VLTI, which is now used to extend our survey sample to the Southern hemisphere and to fainter targets. A first measurement of the exozodi/star flux ratio as a function of wavelength within the H band is presented, thanks to the low spectral resolution capability of PIONIER. Finally, we also briefly discuss our plans for extending the survey to fainter targets in the Northern hemisphere with an upgraded version of the FLUOR beam combiner.
The Role of Wealth in the Economy: the 2002 Annual Meeting Papers of the Royal Netherlands Economic Association

This study is an introduction to and summary of the 2002 Annual Meeting papers of the Royal Netherlands Economic Association. The general theme of this year's Annual Meeting is 'The role of wealth in the economy'. It is covered by 5 papers, which address the following topics: (i) household portfolio behaviour, (ii) the link between household savings and house prices, (iii) pension savings from a macro perspective, (iv) capital structure and corporate investment, and (v) wealth effects and monetary policy. All papers mainly concentrate on the Dutch situation, with the exception of (v), which focuses on the euro area. The study not only gives a brief summary of each of the Annual Meeting papers, but also seeks to provide the reader with a broader perspective by emphasising international stylised facts and (recent) developments in the relevant literature.

Impact of Air Humidity Fluctuation on the Rise of PM Mass Concentration Based on the High-Resolution Monitoring Data

ABSTRACTHourly particulate matter mass concentrations and meteorological parameters, recorded by the China National Environmental Monitoring Center (CNEMC) and China Observatory, between June 2013 and March 2016 in Beijing, Xi’an, Shanghai and Guangzhou were examined to explore correlations. Characteristics of a rapid (abrupt) rise in PM2.5 mass concentration during early stage of a serious urban PM pollution event were examined and compared with pollution events with a gradual (accumulative) rise in PM2.5 mass concentration. The accumulative rise in air pollution is characterized by a prolonged slow PM2.5 growth rate (3–5 µg m–3 h–1), and could eventually lead to middle level pollution (ambient PM2.5 mass concentration of about 150 µg m–3), accompanied with an uncertain temporal variation in SO2, NO2, O3 and CO concentrations. The abrupt rise process is characterized by a short-term high aerosol growth rate (> 10 µg m–3 h–1), and could eventually form severe air pollution (PM2.5 mass concentration exceeds 250 µg m–3), with a constant increase in gaseous pollutants concentrations. The average relative humidity (RH) was observed to have a less impact on the rise of PM2.5 concentration, but the fluctuation in RH was found to have a strong correlation with the rise in PM2.5 concentration. Further analysis has indicated that both abrupt and accumulative rise in PM2.5 mass concentration could be due to the RH fluctuation in atmosphere. The RH variation is important for the study of the fine-particle growth and for prediction of PM pollution episodes.
LA-ICP-MS U-Pb apatite dating of Lower Cretaceous rocks from teschenite-picrite association in the Silesian Unit (southern Poland)

Abstract The main products of volcanic activity in the teschenite-picrite association (TPA) are shallow, sub-volcanic intrusions, which predominate over extrusive volcanic rocks. They comprise a wide range of intrusive rocks which fall into two main groups: alkaline (teschenite, picrite, syenite, lamprophyre) and subalkaline (dolerite). Previous 40Ar/39Ar and 40K/40Ar dating of these rocks in the Polish Outer Western Carpathians, performed on kaersutite, sub-silicic diopside, phlogopite/biotite as well as on whole rock samples has yielded Early Cretaceous ages. Fluorapatite crystals were dated by the U-Pb LA-ICP-MS method to obtain the age of selected magmatic rocks (teschenite, lamprophyre) from the Cieszyn igneous province. Apatite-bearing samples from Boguszowice, Puńców and Lipowa yield U-Pb ages of 103± 20 Ma, 119.6 ± 3.2 Ma and 126.5 ± 8.8 Ma, respectively. The weighted average age for all three samples is 117.8 ± 7.3 Ma (MSWD = 2.7). The considerably smaller dispersion in the apatite ages compared to the published amphibole and biotite ages is probably caused by the U-Pb system in apatite being less susceptible to the effects of hydrothermal alternation than the 40Ar/39Ar or 40K/40Ar system in amphibole and/or biotite. Available data suggest that volcanic activity in the Silesian Basin took place from 128 to 103 Ma with the the main magmatic phase constrained to 128-120 Ma.
Musical Source Separation using Generalised Non-negative Tensor Factorisation Models

A shift-invariant non-negative tensor factorisation algorithm for musical source separation is proposed which generalises previous work by allowing each source to have its own parameters rather a fixed set of parameters for all sources. This allows independent control of the number of allowable notes, number of harmonics and shifts in time for each source. This increased flexibility allows the incorporation of further information about the sources and results in improved separation and resynthesis of the separated sources.
Growth and Competitiveness of Non-Traditional Agricultural Exports in Zambia

This study investigates the determinants of growth and competitiveness of Zambia’s flower exports to three main export destinations—the Netherlands, the UK and Germany—using annual time series data from 1990 to 2010. Acknowledging that time series data are often nonstationary, leading to misleading economic analyses, the study employs cointegration and error correction models to establish factors of conditions growth and competitiveness of Zambia’s flower exports. The results show that supply and competitiveness of flower exports are positively influenced by domestic flower production, real GDP and population of importing countries, relative depreciation of domestic currency and world export prices. In contrast, exports from competing countries and real interest rates were found to negatively influence flower exports. This seems to suggest that monetary policies and exchange rate regimes that promote trade are required for enhancing and fostering an environment favorable for flower production and exporting. In addition, the replacement of Zambia’s flower exports by those from other countries dictates that there must be a quality improvement so the country’s exports can compete favorably with those from other countries.
Endoscopic mucosal resection with anchoring of the snare tip: multicenter retrospective evaluation of effectiveness and safety

Abstract Background Endoscopic mucosal resection (EMR) with snare is the recommended technique to resect non-invasive colorectal neoplastic lesions between 10 and 30 mm in diameter. The objective of EMR is to resect completely the neoplastic tissue en bloc and preferably with free margins (R0), avoiding recurrences. Anchoring the tip of the snare in the submucosa is a technical trick that allows snare sliding to be reduced and larger pieces to be caught. The aim of the present study was to evaluate the effectiveness and safety of anchoring-EMR (A-EMR). Methods This was a retrospective analysis of A-EMR procedures for lesions of diameter between 10 and 30 mm (endoscopic evaluation) performed consecutively in four French centers between May 2017 and January 2018. A-EMR was routinely performed for all EMR using Olympus conventional snares (10 or 25 mm). The primary outcome was evaluation of the proportion of R0 resections. Results A total of 141 A-EMR procedures were performed by 10 operators. Mean lesion size was 19.8 mm. Anchoring was feasible in 96.5 % of cases. There were 81.6 % en bloc resections and 70.2 % R0 resections, with the percentage of procedures decreasing with increasing lesion size (82.8 % < 20 mm, 55.3 % 21 – 30 mm, and 50.0 % > 30 mm, P = 0.002). Complete perforations closed endoscopically occurred in 3/141 cases (2.1 %); none occurred in lesions < 20 mm in size (0 /87). Conclusion The A-EMR technique appears to be promising with a high proportion of R0 for lesions of 10 – 20 mm in size without any perforations. It could also offer an alternative to endoscopic submucosal dissection (ESD), or to hybrid techniques to reach R0 for lesions between 20 and 30 mm in size.
Part II: Prevalences of major skin diseases in cattle, sheep and goats at Adama Veterinary Clinic, Oromia regional state, Ethiopia

Cette etude a ete menee entre Decembre 2006 et Mai 2007 afin d'identifier les principales maladies cutanees des ruminants de la region d'Oromie. Pour cela, 584 bovins, 377 ovins et 295 caprins des 2 sexes (811 femelles et 445 mâles) divises en jeunes et en adultes (266 et 990 respectivement) ont ete examines. La prevalence globale des maladies cutanees a ete de 15.41 % (90 cas) chez les bovins et de 25 % chez les petits ruminants (168 cas), les mâles et les jeunes etant significativement les plus souvent affectes dans les 3 especes etudiees. Chez les bovins, les ectoparasites ont ete principalement responsables des lesions cutanees (77 cas sur 90) et ont infeste de facon privilegiee les mâles et les jeunes, alors que les cas d'ectoparasitisme se sont averes moins frequents chez les petits ruminants (44.6 % des cas) et particulierement chez les chevres (prevalence : 7.78 %). Les principaux ectoparasites identifies dans la region d'Oromie ont ete les tiques (Ambylomma, Boophilus et Hyalomma) chez les bovins et les moutons (avec des prevalences de 6.34 % et 4.77 % respectivement), les poux (Damalina et Linognathus) (3.94 % chez les bovins et 6.40 % chez les petits ruminants) et Demodex a un moindre degre (1.88 % chez les bovins et 1.19 % chez les petits ruminants). La pediculose a preferentiellement affecte les jeunes de facon generale (p < 0.05) et les bovins issus de croisements (p < 0.001). Les autres maladies cutanees n'ont ete que ponctuellement rencontrees chez les bovins (prevalence: 2.20 %) contrairement aux petits ruminants (93 cas sur 168) chez lesquels le risque infectieux etait augmente chez les mâles et les jeunes (surtout les jeunes moutons). Alors que la Lumpy skin disease a ete rarement diagnostiquee chez les bovins, la prevalence des pox virus s'est revelee relativement elevee chez les ovins (10.34 %) et chez les caprins (12.88 %). Les cas d'ecthyma contagieux ont represente 1.76 % des cas observes chez les petits ruminants et la prevalence de la dermatophilose est restee relativement faible allant de 0.53 % chez les chevres a 1.20 % chez les bovins. Cette etude demontre que les maladies cutanees constituent un probleme majeur de sante chez les ruminants dans la region d'Oromie entrainant de lourdes pertes economiques et qu'elles necessitent urgemment la mise en place de procedures de controle.
Patient-reported outcomes for tofacitinib with and without methotrexate, or adalimumab with methotrexate, in rheumatoid arthritis: a phase IIIB/IV trial

Objective To provide the first direct comparison of patient-reported outcomes (PROs) following treatment with tofacitinib monotherapy versus tofacitinib or adalimumab (ADA) in combination with methotrexate (MTX) in patients with rheumatoid arthritis (RA) with inadequate response to MTX (MTX-IR). Methods ORAL Strategy (NCT02187055), a phase IIIB/IV, head-to-head, randomised controlled trial, assessed non-inferiority between tofacitinib 5 mg two times per day monotherapy, tofacitinib 5 mg two times per day+MTX and ADA 40 mg every other week+MTX. PROs assessed included the following: Patient Global Assessment of disease activity (PtGA), Pain, Health Assessment Questionnaire-Disability Index, Functional Assessment of Chronic Illness Therapy-Fatigue and 36-Item Short-Form Health Survey (SF-36) summary and domain scores. Results Substantial improvements from baseline were reported across all PROs in all treatment arms, which, in the majority, met or exceeded minimum clinically important differences. Compared with tofacitinib monotherapy, tofacitinib+MTX combination treatment conferred significantly greater improvements in PtGA, Pain and SF-36 physical component summary scores at month 6. Statistically or numerically greater improvements were often, but not uniformly, reported for combination treatments compared with tofacitinib monotherapy at other time points. Conclusion Treatment with tofacitinib+MTX, ADA+MTX and tofacitinib monotherapy resulted in clinically meaningful improvements in PROs in MTX-IR patients with RA. These were comparatively greater with combination treatments versus tofacitinib monotherapy, although differences between treatment arms were small, limiting our ability to confer clinical meaning. Trial registration number NCT02187055.
SiRNA-Mediated RRM2 Gene Silencing Combined with Cisplatin in the Treatment of Epithelial Ovarian Cancer In Vivo: An Experimental Study of Nude Mice

Introduction: We aimed to explore small interfering (si)RNA silencing of ribonucleotide reductase M2 (RRM2) gene combined with cisplatin for the treatment of human ovarian cancer in nude mice models of subcutaneous transplantation of tumor cells. Methods: After conventional cultivation of human ovarian cancer cell line SKOV3 in vitro, SKOV3 cells were injected into the right back of nude mice by subcutaneous injection to establish the subcutaneous tumor models. Twenty-four tumor-burdened rats were randomly divided into four groups (n=6): siRNA group, siRNA in combination with cisplatin group, cisplatin group, and control group. Intraperitoneal injection of cisplatin and subcutaneous injection of siRNA were performed weekly. Tumor volume was measured, and tumor growth inhibition rate was calculated. RRM2 expression at the mRNA and protein levels was detected by reverse transcription-polymerase chain reaction and immunohistochemistry. Results: In the siRNA group, the tumor volume and tumor growth inhibition rate were 249.60±20.46 mm³ and 36.39%, respectively. The tumor growth inhibition rate and tumor volume were significantly different between the siRNA and control groups (p<0.05). In the cisplatin group, the tumor volume and tumor growth inhibition rate were 249.86±12.46 mm³ and 41.10%, respectively. The tumor growth inhibition rate and tumor volume were significantly different between the cisplatin and control groups (p<0.05). In the siRNA + cisplatin group, the tumor volume reduced to 180.84±16.25 mm³ and the tumor growth inhibition rate was increased to 64.33%, which were significantly different compared with the control group (p<0.01). Significant downregulation of RRM2 mRNA and protein expression in the tumor tissues was detected by reverse transcription polymerase chain reaction and immunohistochemistry assay (p<0.05). Discussion: siRNA alone or combined with cisplatin can effectively inhibit the growth of human ovarian cancer in nude mice models of subcutaneous transplantation of tumor cells. RRM2 gene silencing may be a potential treatment regimen for ovarian cancer in future.
What Does Research Tell Us about Trends in Dissertations on PBL

The aim of this study is to investigate the research trends in dissertations on PBL from 2002 to 2015 in Turkey. For this purpose, the master's and doctorate dissertations in the National Thesis Database of Council of Higher Education (CoHE) were selected for rigorous content analysis. The analysis was utilized to classify the type of study, the learning domains, research methods, research designs, research domains, subject groups, group sizes, length of treatments and data collection instruments. For analysis purposes, frequencies and percentages were calculated for each category. Additionally, the results obtained in these dissertations were examined and reported separately with regards to cognitive, affective and conative domains. According to analysis results; science is the most favorable learning domain, quantitative methodology is more utilized as compared to qualitative and quantitative methods, cognition and affect followed by cognition only are the mostly utilized research domains, subject groups are predominantly at elementary education level and secondly from teacher education, studies preferred to have a group size of 41-80, the treatments on PBL research last mostly four to six weeks, and finally majority of the studies use achievement tests and attitude scales as instruments of measurement.
Momentary Lapses: Moment Expansions and the Robustness of Minimum Distance Estimation

This paper explores the robustness of minimum distance (GMM) estimators focusing particularly on the effect of intermediate covariance matrix estimation on final estimator performance. Asymptotic expansions to order Op(n−3/2) are employed to construct O(n−2) expansions for the variance of estimators constructed from preliminary least-squares and general M-estimators. In the former case, there is a rather curious robustifying effect due to estimation of the Eicker-White covariance matrix for error distributions with sufficiently large kurtosis.
